Abstract:Mental health examination is a way to evaluate the mental health status of the examinee in health examination, providing basis for the adjustment of psychological status for early diagnosis and early treatment. However, mental health examination in China is still in its infancy, and the evaluation processes, methods, and tools vary greatly among different institutions. Therefore, based on relevant literatures, this expert consensus summarizes how to scientifically and normatively carry out mental health examination from 8 aspects: purpose and role, implementation path, information collection, core evaluation dimensions, basic project recommendations, ethical norms, result feedback, and after-examination services, aiming to provide reference for the implementation of mental health examination in health examination institutions.

Abstract:Due to the influence of objective environmental stimuli, individuals in isolated and confined environments (ICE) are prone to negative emotions and stresses, resulting in a strong sense of isolation and separation. Therefore, studying the impact of long-term ICE tasks on individual mental health and the methods and mechanisms of psychological regulation are beneficial for improving the psychological health level of the members and helping them better adapt to the environment to complete tasks. By analyzing the individual coping strategies, adaptation skills, emotional regulation, and team management for ICE, the psychological regulation of long-term ICE tasks can be roughly summarized into 3 stages: pre task preparation, in task support, and post task readjustment. Using psychological health checklists, isolated and confined extreme-questionnaire and other scales for monitoring, implementing strategies to promote positive emotions and task orientation, allowing a mediating role in resilience, cultivating appropriate humor, and effective communication and conflict management among teams are all important ways to adapt to ICE.

Abstract:Objective To investigate the status and influencing factors of mental health services in primary and secondary schools in Shanghai, so as to provide evidence for training professional mental health teachers and delivering mental health services to children and adolescents effectively. Methods Totally 422 mental health teachers from 14 districts of Shanghai were investigated with a self-designed questionnaire on mental health services in primary and secondary schools. Pearson Chi-square test and Student’s tt test were used to compare the differences in sohool mental health services and influencing factors among mental health teachers with different educational backgrounds, and a structural equation model was constructed to analyze the influencing factors of students’ access to mental health services. Results The major of mental health teachers were mainly applied psychology (n=124, 29.38%), education (n=117, 27.73%), and developmental and educational psychology (n=65, 15.40%). The top 3 mental health problems for students were social, interpersonal or family problems, anxiety, stress or school phobia, and adjustment issues. The organizations that had signed agreements or cooperated with school to provide mental health services were primarily the district mental health centers (n=376, 89.10%), community health centers (n=155, 36.73%) and local hospitals (n=106, 25.12%). The proportions or scores of mental health teachers with master’s degree were significantly higher than those with bachelor’s degree for school mental health services, prevention and early intervention programs, data collection, and influencing factors of students’ access to mental health services (all P<0.05). The need for mental health services (n=328, 77.73%) and the number of students served (n=314, 74.41%) were increased, while the funds for mental health services (n=212, 50.24%) and the number of school mental health staff (n=226, 53.55%) remained unchanged in the past 3 years. A structural equation model with 3 dimensions of school, family and society was constructed for influencing factors of students’ access to mental health services (χ2/df=2.708, root mean square error of approximation=0.064, normalized fitting index=0.947, goodness-of-fit index=0.946, adjusted goodness of fit index=0.912, comparing fitting index=0.965, relative fitting index=0.926, Tucker-Lewis index=0.952, increasing fitting index=0.966, root mean square residual=0.046). Conclusion Mental health services in primary and secondary schools in Shanghai has achieved remarkable progress. Post-employment training for full-time mental health teachers needs to be strengthened. The supply of school mental health resources should be guaranteed from multiple pathways, such as coordination of school, family and society, and medicine-education alliance. Special funds for mental health should be guaranteed.

Abstract:Objective To investigate the status of learning burnout, mental health and coping styles of adolescents with learning difficulties, and analyze its influencing factors, so as to provide guidance for preventing and correcting adolescents’ learning difficulties. Methods A questionnaire survey was conducted among 102 adolescents with learning difficulties. The general information was collected with a self-designed questionnaire. The learning burnout, mental health and coping styles were investigated by the adolescent learning burnout scale, symptom checklist 90 (SCL-90), and middle school students’ coping style scale. The scores of learning burnout, mental health and coping styles among adolescents with learning difficulties with different demographic characteristics were compared, and linear regression analysis was used to explore the influencing factors of learning burnout, mental health and coping styles. Results The total score of adolescent learning burnout scale of 102 adolescents with learning difficulties was 55.71±9.86, and the average score of SCL-90 was 2.60±0.80. In coping styles, the score of problem solving was 19.11±6.08, seeking help was 19.94±10.22, enduring was 8.86±2.06, avoiding was 14.31±4.15, venting was 10.35±3.06, and fantasizing was 6.75±3.22. Females were more likely to suffer from learning burnout and mental health problems, while males were more likely to use problem solving coping style (all P<0.05). Individuals with poor family economic status were more likely to use venting coping style, while those with better family economic status were more likely to use fantasizing coping style (both P<0.05). Individuals with good family relationship had less learning burnout, while those with poor family relationship were more inclined to use venting coping style (both P<0.05). Individuals from divorced families had more serious mental health problems, while those from intact families were more inclined to use problem solving coping style (both P<0.05). Learning burnout and mental health problems were more serious in individuals who experienced major changes during their growth period (both P<0.05). Individuals with shorter nighttime sleep duration had more serious learning burnout and mental health problems (both P<0.05). Those who had not experienced lockdown or isolation during the epidemic of coronavirus disease 2019 were more likely to use problem solving coping style (P<0.05). Linear regression analysis showed that gender, family relationship and nighttime sleep duration were the influencing factors of learning burnout (all P<0.05). Nighttime sleep duration, major changes during the growth period and gender were the influencing factors of mental health (all P<0.05). Family situation was the influencing factor of problem solving in coping styles, and family relationship was the influencing factor of venting in coping styles (both P<0.05). Conclusion Adolescents with learning difficulties have obvious learning burnout and poor mental health. Factors such as gender, family relationship, and sleep duration should be emphasized in the future.

Abstract:Objective To evaluate the inhibitory effect of Sisheng decoction on the hippocampal neuron injury induced by electromagnetic radiation in rats. Methods Rats were irradiated with electromagnetic radiation sources for 4 weeks, with low-, medium-, and high-dose radiation power densities of 10, 20, and 40 mW/cm2, respectively. The Morris water maze was used to evaluate the effect of Sisheng decoction on the learning and memory decline caused by electromagnetic radiation in rats, with physiological saline as the blank control and anduolin capsule as the positive control. TUNEL kit and flow cytometry were used to detect the level of apoptosis in hippocampal neurons of rats with electromagnetic radiation injury, and reactive oxygen species (ROS) kit and flow cytometry were used to detect the ROS content in hippocampal neurons of rats. Results The results of the Morris water maze test showed that on the 7th day after high-dose radiation, the average escape latency (AEL) of the rats in the blank control group was significantly longer than that in the Sisheng decoction group and anduolin group, and the AEL of the rats in the anduolin group was significantly longer than that in the Sisheng decoction group (all P<0.05). On the 3rd day after medium-dose radiation, the AEL of the rats in the blank control group was significantly longer than that in the Sisheng decoction group and anduolin group (both P<0.05); on the 14th and 28th days, the AEL of the rats in the blank control group and anduolin group was significantly longer than that in the Sisheng decoction group (all P<0.05). After exposed to low-dose radiation, there was no significant difference in AEL between the blank control group and the Sisheng decoction or anduolin groups (both P>0.05). The apoptosis test result confirmed that the apoptosis rates of hippocampal neurons in rats exposed to high- and medium-dose radiation were significantly higher than that exposed to low-dose radiation (both P<0.05). After exposed to high-, medium-, and low-dose radiation, the neuronal apoptosis rates of the rats in the anduolin group and Sisheng decoction group were significantly lower than those in the blank control group (all P<0.05). After exposed to high-dose radiation, the apoptosis rate of neurons of the rats in the Sisheng decoction group was significantly lower than that in the anduolin group (P<0.05). There were no significant differences in ROS contents in hippocampal neurons among rats under high-, medium-, or low-dose radiation (P>0.05). However, the ROS contents in neurons of the anduolin group and Sisheng decoction group were significantly lower than that in the blank control group (both P<0.05). After exposed to medium-dose radiation, the ROS inhibition effect of the Sisheng decoction group was stronger than that in the anduolin group (P<0.05). Conclusion Sisheng decoction can inhibit the apoptosis of hippocampal neurons in rats, reduce the ROS content in their cells, and alleviate the injury to learning and memory caused by electromagnetic radiation in rats.

Abstract:Objective To compare the tumor and renal function outcomes of patients with localized renal cancer at least 10 years after laparoendoscopic single-site radical nephrectomy (LESS-RN) or conventional laparoscopic radical nephrectomy (CL-RN). Methods Totally 31 pairs of T1a-T2a localized renal cancer patients treated with LESS-RN or CL-RN in The First Affiliated Hospital of Naval Medical University (Second Military Medical University) during 2009-2012 were matched by age, body mass index, and tumor size. Baseline characteristic, surgical data, pathological results, and follow-up information were analyzed to evaluate the long-term outcomes between the 2 groups. Results There were no significant differences between the LESS-RN and CL-RN groups in operative time ([179.7±43.0] min vs [172.6±50.9] min, P=0.349), estimated blood loss (100[50, 200]mL vs 100[50, 150]mL, P=0.871), or hospital stay (6[5, 7]d vs 7[6, 9]d, P=0.080). Only 1 intraoperative complication occurred in both groups, while no postoperative complication occurred in the LESS-RN group and 3 in the CL-RN group. The follow-up time was (138.0±9.0) months in the LESS-RN group and (137.8±9.8) months in the CL-RN group (P=0.730). The overall survival rate (80.6% vs 74.2%, P=0.181), cancer-specific survival rate (93.6% vs 96.8%, P=0.554), change in creatinine level (32 [17, 45] μmol/L vs 20[5, 47]μmol/L, P=0.098) or estimated glomerular filtration rate ([60.2±20.9]mL·min-1· (1.73 m2)-1 vs[66.7±27.8]mL·min-1·(1.73 m2)-1, P=0.342) were not significantly different between the 2 groups. Conclusion LESS-RN is a safe and feasible surgical method for localized renal cancer with long-term tumor efficiency and renal function outcomes comparable to CL-RN.

Abstract:Objective To explore the risk factors of acute non-simple appendicitis in children, and to establish a prediction model. Methods Retrospective analysis was performed with the clinical data of 582 children with acute appendicitis who underwent laparoscopic appendectomy and were diagnosed by pathology in our hospital from Jan. 2018 to Dec. 2019. According to the intraoperative findings and pathological types, the patients were divided into non-simple appendicitis group (382 cases, including suppurative, gangrene and perforation) and simple appendicitis group (200 cases). The clinical data of the 2 groups were compared and statistically significant variables were used for multivariate logistic regression analysis to identify risk factors of acute non-simple appendicitis, and finally to establish a logistic regression prediction model. The performance of the prediction model was assessed by receiver operating characteristic (ROC) curve. Prospective validation of the prediction model was conducted with 160 patients with acute appendicitis undergoing appendectomy in our hospital from Jan. to Dec. 2020. Results Of the 582 patients, 382 (65.6%) had non-simple appendicitis. Multivariate logistic regression analysis demonstrated that white blood cell (WBC) (odds ratio[OR]=1.305, 95% confidence interval[CI]1.189-1.432, P<0.001), neutrophil percentage (NP) (OR=1.046, 95% CI 1.012-1.080, P=0.007), C reactive protein (CRP) (OR=1.046, 95% CI 1.010-1.082, P=0.011), and albumin (ALB) (OR=0.973, 95% CI 0.952-0.995, P=0.014) were independent risk factors for non-simple appendicitis in children. The logistic regression equation based on the 4 factors was logit(P)= —5.614+0.263×WBC+0.045×NP+0.045×CRP—0.027×ALB. The probability model was P=1/(1+Exp[—5.614+0.263×WBC+0.045×NP+0.045×CRP—0.027×ALB]). The Hosmer-Lemeshow test indicates that this model has high fitting degree (P=0.622). The area under curve of the ROC curve for the prediction model was 0.931 (95% CI 0.896-0.957, P<0.001), with a sensitivity of 0.830 and a specificity of 0.905. Prospective validation showed that the sensitivity and specificity of the prediction model were 0.882 and 0.820, respectively. Conclusion Increased white blood cell count, neutrophil percentage and CRP level, and hypoalbuminemia are independent risk factors for acute non-simple appendicitis in children. The prediction model based on the above factors has good diagnostic value and can help differentiate between acute simple and non-simple appendicitis.

Abstract:Objective To analyze the influencing factors of the prognosis of invasive breast cancer by using machine learning algorithms and construct prognostic model. Methods The clinical and pathological data of 24 584 patients with invasive breast cancer from 2010 to 2015 were collected from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate analysis and logistic regression analysis were used to screen the prognostic variables. Five machine learning classification algorithms including logistic regression, decision tree, support vector machine, random forest and artificial neural network were used to establish the prediction model of survival prognosis. The prediction ability of each modeling method was evaluated. Sensitivity, specificity, accuracy and area under curve of receiver operating characteristic curve were used as evaluation indexes of the model. Results Among the 21 model input variables, histological grade, T stage, N stage, M stage, brain metastasis, expression status of human epidermal growth factor receptor 2 and surgical treatment had great impacts on the survival prognosis of patients with invasive breast cancer. Among the prognostic models constructed by 5 machine learning algorithms, random forest and artificial neural network models had better predictive effects. Conclusion The prognosis model of invasive breast cancer constructed by machine learning algorithm has good prediction effect, which can assist doctors to judge the prognosis and treatment effect of patients with invasive breast cancer.

Abstract:Objective To investigate the mediation effects of positive coping style and self-esteem on the relationship between mental resilience and fatigue. Methods A total of 1 092 males were selected by cluster sampling, and were surveyed using multidimensional fatigue inventory scale, the Connor-Davidson resilience scale, simplified coping style questionnaire, and Rosenberg self-esteem scale. Pearson correlation analysis was used to explore the relationship between variables, and hierarchical linear regression was used to analyze the predictive value of mental resilience, positive coping style, and self-esteem for fatigue. Structural equation model was constructed to investigate the mediation roles of positive coping style and self-esteem in the relationship between mental resilience and fatigue. Results A total of 1 065 valid questionnaires were collected, with an effective rate of 97.53%. The results of Pearson correlation analysis suggested that fatigue was negatively associated with mental resilience, positive coping style, and self-esteem (r=—0.619, —0.538, —0.589; all P<0.01), and positively associated with negative coping style (r=0.340, P<0.01); mental resilience was positively correlated with positive coping style and self-esteem (r=0.706, 0.583; both P<0.01), but not correlated with negative coping style (r=0.014, P>0.05). Self-esteem was negatively correlated with negative coping style (r=—0.181, P<0.01), and positively correlated with positive coping style (r=0.474, P<0.01). The results of hierarchical linear regression showed that mental resilience could independently explain 38.3% of the variance of fatigue (P<0.01), and self-esteem and positive coping style could explain an additional 9.2% variance of fatigue (P<0.01). The model fit index of structural equation model was χ2=31.404, df=7, χ2/df=4.486, with the comparative fit index being 0.994, Tucker-Lewis index being 0.998, and root mean square error of approximation being 0.014. The mediation effect analysis showed that the mediation effects of positive coping style (P=0.01) and self-esteem (P<0.001) were significant, with that of self-esteem being greater than that of positive coping style (P=0.007), and the direct effects of mental resilience was significant (P<0.001). Conclusion Self-esteem and positive coping style have partial mediation effect on the relationship between mental resilience and fatigue, and the mediation effect of self-esteem is greater, suggesting that mental resilience, self-esteem and positive coping style are protective factors of fatigue. Carrying out resilience training, improving self-esteem, and adopting positive coping style can reduce the fatigue.

Abstract:Hepatocellular carcinoma is the most common type of primary liver cancer, characterized by rapid progression, strong invasion, and diverse treatments. However, due to the large number of genes involved in its development and complicated mechanism, treatment resistance inevitably emerges, leading to ineffective therapeutic effects. Up to now the drug resistance mechanism has not been completely clarified. Long noncoding RNAs (lncRNAs) are a new class of noncoding RNAs with multiple biological functions, and may be involved in the development, transformation, and invasion of hepatocellular carcinoma through gene mutation, as well as in drug resistance by influencing the immune microenvironment of tumors and regulating the biological functions of tumor cells. In this paper, we reviewed the roles of lncRNAs in the chemotherapy, targeted therapy and immunotherapy resistance of hepatocellular carcinoma, hoping to provide new insight for drug resistance in hepatocellular carcinoma.

Abstract:Hepatobiliary and pancreatic tumors are high-incidence diseases of the digestive system with high malignancy and poor clinical prognosis. Failure to achieve radical resection and sufficient dissection of lymph nodes during surgical treatment is the main reason for tumor recurrence and metastasis. Indocyanine green (ICG) fluorescence staining has been commonly used in the detection of liver function and the evaluation of effective liver blood volume in the past. In recent years, it has been gradually applied to the intraoperative diagnosis, treatment and monitoring of hepatobiliary and pancreatic tumor metastases, in order to achieve better radical results of surgery. This paper reviews the application of ICG fluorescence staining in hepatobiliary and pancreatic tumor metastases based on related literatures.

Abstract:Objective To investigate the effect of 40 m hyperbaric air exposure on brachial artery function of divers. Methods Five divers were enrolled and exposed to hyperbaric air with a maximum pressure of 40 m for a total of 190 min. The brachial artery diameter, systolic peak velocity (SPV) and resistance index (RI) were measured by Doppler ultrasonography before and after hyperbaric air exposure, and flow-mediated dilation (FMD) was calculated to evaluate the effect of hyperbaric air exposure on brachial artery function. Results Compared with before hyperbaric air exposure, the brachial artery diameter was decreased (P>0.05), RI and FMD were increased slightly (P>0.05), while SPV was decreased significantly (P<0.05) after hyperbaric air exposure. Conclusion Exposure to hyperbaric air at 40 m can lead to brachial artery contraction, increase resistance, and decrease flow velocity, but it has a slight impact on the brachial artery function, with no significant change in FMD.

Abstract:Objective To study the effect of a new type of anti-injury thoracic puncture and catheterization equipment in the treatment of closure hemopneumothorax. Methods Four healthy adult beagles were randomly divided into 2 groups: group 1 and group 2, with 2 beagles in each group, and the cross-control method was used to conduct the experiment. Two groups of beagles were used to establish hemopneumothorax models. In the group 1, the left thoracic cavities of beagles were treated with traditional closed thoracic drainage surgery, while the right thoracic cavities were treated with a new type of anti-injury thoracic puncture and catheterization equipment. In the group 2, the left thoracic cavities of beagles were treated with a new type of anti-injury thoracic puncture and catheterization equipment, while the right thoracic cavities were treated with traditional closed thoracic drainage surgery. After 1 month of treatment, the experimental methods of the 2 groups were exchanged. The intraoperative puncture and catheterization time, maximum angle of thoracic catheterization, postoperative incision inflammation stimulation, postoperative extubation time, and postoperative complications of the 2 methods were compared. Results Compared with the traditional closed thoracic drainage surgery, the new type of anti-injury thoracic puncture and catheterization equipment had obvious advantages in reducing the time of puncture and catheterization ([47.13±11.56] s vs [88.13±16.84] s, P=0.002), adjusting the maximum angle of thoracic catheterization ([118.38±11.07]° vs [102.25±9.92]°, P=0.015), reducing the inflammatory stimulation of incision, and shortening the postoperative extubation time ([47.00±2.70] h vs [51.62±3.52]h, P=0.019). Conclusion The new type of anti-injury thoracic puncture and catheterization equipment has certain advantages in the treatment of closure hemopneumothorax, and is suitable for the evacuation and first aid of a large number of wounded or battlefield patients.

Abstract:Objective To study the effect of night vision goggle (NVG) on visual performance, so as to provide an experimental basis for NVG ground simulation training. Methods Twenty volunteers with normal vision were recruited. The static distanced visual acuity, depth perceptual error, dynamic visual acuity (DVA; 3.0, 4.5, 6.0, and 7.5 km/h), visual cognition time, and visual search time were measured with NVG in the full moonlight environment (0.1 lx). The effect of NVG on visual performance in the full moonlight environment was assessed by comparing with the same indicators measured with the naked eye in the twilight light environment (15 lx). Also, the ability to judge the positions of red and blue light (2 cd/m2) in a dark room was compared between wearing NVG and the naked eye. Results Compared with the naked eye in the twilight environment, DVA for all 4 speeds (3.0, 4.5, 6.0, and 7.5 km/h) was decreased (all P<0.001), depth perceptual error and visual search time were increased (both P<0.05) in the full moonlight environment with the NVG, whereas there were no significant differences in static distanced visual acuity or visual cognitive time (both P>0.05). The scores of wearing NVG for correctly judging the relationship between red and blue light were significantly lower than those of the naked eye (P=0.001). Wearing NVG was more likely to misjudge the red light closer to them (P=0.001). Conclusion DVA, depth perception and visual search capability are the weak points for NVG to improve the visual performance. NVG ground simulation training should emphasize the search of dynamic targets, recognition, and training of depth perception. Flying with NVG should not use the color light as a cue for distance judgments, and should focus on alternating between NVG and the naked eye to enhance the ability to acquire systematic information and build situational awareness.

Abstract:Objective To investigate the clinical efficacy of distal oblique bundle reinforcement for the treatment of distal radioulnar joint (DRUJ) instability. Methods The clinical data of 24 patients with DRUJ instability treated with distal oblique bundle reinforcement in our hospital from Jan. 2019 to Jan. 2022 were retrospectively analyzed. The age, surgical site, follow-up time, wrist visual analogue scale (VAS), range of motion (pronation+supination) of forearm, the quick disabilities of the arm, shoulder and hand (QuickDASH) score before operation and at the last follow-up, and postoperative complications of the patients were collected. The wrist VAS scores and functional indexes were compared before and after operation. Results The average follow-up time was 12-21 (15.38±2.76) months. The wrist VAS score was 4-8 (6.13±1.08) before operation and 1-3 (1.25±0.53) at the last follow-up, showing improvement after operation (P<0.001). The range of motion (pronation+supination) of forearm was 95°-145° (120.83±14.35)° before operation and 145°-180° (175.21±6.51)° at the last follow-up, also showing increasement after operation (P<0.001). The QuickDASH score was 34-98 (78.58±19.22) before operation and was 10-34 (21.46±6.30) at the last follow-up, with significant difference (P<0.001). One patient had limited forearm pronation and 1 patient had DRUJ instability, which recovered after corresponding treatments. No patients had rejection or infection caused by allogeneic tendon, or important nerve and vascular injuries caused by operation. Conclusion The clinical effect of distal oblique bundle reinforcement is satisfactory, and the incidence of complications is low, indicating it is a safe and effective surgical method for DRUJ instability.

Abstract:Objective To investigate the applicability of the Chinese version of the Edinburgh postnatal depression scale (EPDS) for postpartum depression screening in puerperal women using Rasch analysis, so as to provide reference for the clinical use of appropriate postpartum depression screening tools. Methods A cross-sectional study was conducted on 234 puerperal women in the outpatient department of obstetrics of a tertiary general hospital in Yangzhou, Jiangsu province. Rasch model was used to analyze the unidimensionality, reliability, difficulty and model fit of EPDS items. Results The Chinese version of EPDS had 10 items, and the Cronbach’s α coefficient was 0.812; it had unidimensionality, the reliability of the scale was 0.82, and the point biserial were 0.46 to 0.76. The fitting index of each item of the scale was good, the infit mean square value ranged from 0.64 to 1.29, and the outfit mean square value ranged from 0.62 to 1.34. The range of item difficulty was—2.26 to 3.16, matching well with the depression level of the participants. The options of each item were independent and had good discrimination. Conclusion The Chinese version of EPDS has good reliability and unidimensionality, and has good applicability in screening postpartum depression in puerperal women. Based on Rasch model analysis, it is found that the scale is primarily suitable for postpartum depression patients with mild to moderate severity, being less sensitive to high levels of depression. The effectiveness and sensitivity of the scale in clinical application can be further improved by adding items with higher difficulty levels.
