ObjectiveTo investigate the mechanism of Biejiajian Wan in the intervention of primary liver cancer based on long non-coding RNA SNHG5 （lncRNA SNHG5）/micro RNA-26a-5p （miRNA-26a-5p）/glycogen synthase kinase-3β （GSK-3β） signal axis. MethodDouble luciferase reporting assay was used to verify the targeted interaction between lncRNA SNHG5 and miRNA-26a-5p， miRNA-26a-5p， and GSK-3β in HepG2 cells. Nude-mouse transplanted tumor model of human HepG2 were established and randomly divided into model group， Biejiajian Wan low-dose group （0.5 g·kg^-1）， medium-dose group （1.0 g·kg^-1）， and high-dose group （2.0 g·kg^-1）， and sorafenib group （100 mg·kg^-1）， with 10 mice in each group. The mice were given intragastric administration of normal saline or drug for 28 days， and the tumor volume was measured at different time. Hematoxylin-eosin （HE） staining was used to observe the histological changes of tumors. The nucleic acid levels of lncRNA SNHG5， miRNA-26a-5p， GSK-3β， and β-catenin mPNA in tumor tissue were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. The protein expression levels of GSK-3β and β-catenin in tumor tissue were detected by western blot. ResultCompared with the SNHG5-WT （wild type） + miRNA NC （negative control） group， the relative luciferase activities of the SNHG5-WT + miRNA-26a-5p mimic group were decreased （P<0.05）. Compared with the GSK-3β-WT + miRNA NC group， the relative luciferase activity of the GSK-3β-WT + miRNA-26a-5p mimic group was decreased （P<0.05）. Compared with the model group， the tumor volume of Biejiajian Wan low-dose， medium-dose， and high-dose groups was significantly decreased （P<0.05， P<0.01）. Compared with the model group， the cells in the tumor tissue of nude mice in each dose group of Biejiajian Wan were sparsely arranged with necrocytosis， which showed concentration-dependent changes. Compared with the model group， the expression levels of lncRNA SNHG5， GSK-3β， and β-catenin were decreased （P<0.05， P<0.01）， while the expression of miRNA-26a-5p was increased in each dose group of Biejiajian Wan （P<0.05， P<0.01）. Compared with the model group， the protein expression levels of GSK-3β and β-catenin were decreased in each dose group of Biejiajian Wan （P<0.05， P<0.01）. ConclusionBiejiajian Wan may affect the necrosis of liver cancer cells through lncRNA SNHG5/miRNA-26a-5p/GSK-3β signal axis and thus play an anti-tumor role. This research will provide more theoretical basis for the clinical application of Biejiajian Wan.

ObjectiveThis study aims to explore risk factors for the development of major adverse cardiovascular and cerebrovascular events （MACCEs） in middle-aged and elderly patients with type 2 diabetes mellitus complicated with stable angina pectoris （T2DM-SAP） based on real-world clinical data in traditional Chinese medicine （TCM）， so as to develop a COX proportional risk prediction model and visualize the predicted results using a nomogram. MethodBased on the clinical scientific research information sharing system， the medical records of 586 T2DM-SAP patients （45-94 years old） were collected from January 2012 to December 2019， including age， gender， course of disease， major medical history， laboratory examination， tongue image， pulse image， TCM syndrome， and major treatment drugs. MACCE outcome indicators of patients were obtained by telephone follow-up and re-hospitalization records. The data was divided into a training set and a validation set according to 7∶3. In the training set， COX univariate analysis was used to determine the risk factors for MACCE in T2DM-SAP patients， and then variables were screened by forward-backward stepwise regression method， so as to establish a MACCE risk prediction model and construct a nomogram. The predictive efficacy of the model was reflected by the C-index， receiver operating characteristic （ROC） curve， calibration map， and clinical decision curve. ResultThe history of cerebrovascular disease ［Hazard ratio （HR）=1.983， 95% confidence interval （CI，1.314-2.993）］， low-density lipoprotein （LDL-C/mmol·L^-1）≥4.1［HR=2.683， 95%CI（1.461-4.925）］， dull red tongue ［HR=1.955， 95%CI（1.273-3.002）］， dull purple tongue ［HR=4.214， 95%CI（2.017-8.803）］， white thick coating ［HR=3.030， 95%CI（1.634-9.293）］， thin and weak pulse ［HR=2.233， 95%CI（1.283-3.888）］， and syndrome of wind-phlegm blocking collaterals ［HR=2.007， 95%CI（1.179-3.418）］ were found to be risk factors in middle-aged and elderly T2DM-SAP patients. Insulin ［HR=0.604， 95%CI（0.399-0.914）］， glycosidase inhibitor ［HR=0.627， 95%CI（0.409-0.962）］， and TCM treatment ［HR=0.328， 95%CI（0.214-0.503）］ were protective factors in middle-aged and elderly T2DM-SAP patients. The prediction model was constructed based on the above risk factors. The C-index of the model was 0.818 （95% CI 0.777 -0.859） in the training set and 0.814 （95% CI 0.773-0.855） in the validation set， and the change of C-index over time was plotted. The AUC of patients for 5， 10， 15 years in the training set was 0.71， 0.67， and 0.61. The AUC of patients for 5， 10， and 15 years in the validation set was 0.60， 0.68， and 0.63， respectively. The calibration map and clinical decision curves of 5， 10， 15 years were drawn in the training set and the validation set， respectively. The model was well calibrated and clinically effective. ConclusionThe history of cerebrovascular disease， LDL， dull red tongue， dull purple tongue， white thick coating， thin and weak pulse， and syndrome of wind-phlegm blocking collaterals are risk factors for MACCE in middle-aged and elderly T2DM-SAP patients， and insulin， glycosidase inhibitors， TCM treatment are protective factors for MACCE in middle-aged and elderly T2DM-SAP patients. A clinical prediction model is established accordingly. This model has good discrimination， calibration degree， and clinical effectiveness and provides a scientific basis for the prevention and treatment of MACCE in middle-aged and elderly T2DM-SAP patients.

Objective:To evaluate the clinical application and biomechanical characteristics of zygomatic implant supported prosthesis (ZIP) in restoring unilateral maxillary defect and to provide theoretical support for clinical treatment.Methods:A total of 8 patients with unilateral maxillary defect admitted to the Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to June 2018 were selected. Inclusion criteria: unilateral maxillary defect, 18 to 70 years old, no systemic chronic disease, no radiotherapy history, healthy residual dentition, no moderate to severe periodontitis, no loose teeth, and no obvious malocclusion. Two zygomatic implants were implanted on the affected side, and the defects were restored with removable prostheses (RP) immediately after the operation. ZIP was manufactured and placed 6-12 months after implantation. And then, the quality of life after wearing RP and ZIP was evaluated with Dental Impact on Daily Living scale (DIDL). The subjective feelings of patients were evaluated from five aspects of appearance, pain, oral comfort, eating and chewing and general performance. The results were statistically analyzed by independent sample t test. A three dimension model of skull was established with the CT data of a 25-year-old healthy male and the models of zygomatic implants and prosthesis were constructed at the same time. In this composite model, a 150 N vertical force was loaded on the occlusal surface of the prosthetic prosthesis to simulate the bite force, and the stress distribution and concentration points of the zygomatic implant, prosthetic clasps, palatal plate, abutment and other parts were analyzed. The differences between RP and ZIP restoration were compared. Results:A total of 8 patients with unilateral maxillary defect were selected, including 5 males and 3 females, aged from 18 to 63 years, with an average of 48.9 years. A total of 16 zygomatic implants were implanted in 8 patients, and ZIP repair was completed 9-10 months after operation. The result of DIDL scale showed that, in terms of appearance, oral comfort, eating and chewing, general performance, the score of ZIP group was 0.79±0.15, 0.70±0.15, 0.63±0.24, 0.73±0.13 respectively, all of which were significantly higher than those of RP group -0.41±0.22, 0.35±0.22, -0.09±0.34, 0.30±0.19 respectively. Nevertheless, the score of ZIP group in terms of pain was 0.29±0.15, which was lower than that of RP group (0.48±0.23). Except for pain, the other differences were statistically significant ( P<0.05). The biomechanical analysis showed that, compared with RP group, the stress of ZIP was distributed mainly in the zygomatic implants. And the stress of palatal plates, clasps and abutments was reduced significantly and distributed evenly, with no obviously stress concentration point. Conclusions:ZIP can improve appearance, reduce discomfort and increase mastication efficiency. It is a better choice for unilateral maxillary defect restoration.

Objective: To investigate the automatic implicit attitude and explicit stigma of mental illness, and the intervention effectiveness on the stigma of mental illness in college students. Methods: Single category implicit association test(SC-IAT) and questionnaire survey were used to study the degree of implicit and explicit mental illness stigma among 30 college students of Peking University, and investigated the effect of two strategies, education and contact.Data were analyzed by SPSS 22.0 with t-test and variance analysis. Results: The D values of SC-IAT in the three dimensions of cognitive evaluation, emotional response and behavioral tendency of college students were 0.29±0.37, 0.24±0.43, and 0.10±0.43.There was a statistically significant difference between the cognitive evaluation dimension, the emotional response dimension and 0(t=4.069, P<0.01; t=2.925, P<0.01). There was no statistically significant difference between the implicit stigma and the 0 in the behavioral tendency dimension(t=1.423, P=0.167). In the explicit stigma, the mercy dimension score(1.94±0.61) was lower than the median, and the difference was statistically significant(t=-12.286, P<0.01), while the scores of anger dimension(4.62±0.44) and fear dimension (4.55±0.31) were higher than the median(t=13.243, 3.200, both P<0.01). There were no significant differences in the values of implicit and external stigma among pre-intervention, education intervention and after contact(P>0.05). The correct rates of questions "Which of the following situations do you think are considered mentally unhealthy? " and "Which of the following disorders are mental illnesses" (42±13)%, (54±13)%) increased after receiving educational intervention ((49±12)%, (64±13)%), the difference was statistically significant (F=3.682, P<0.05; F=3.576, P<0.05). Conclusion College students have implicit mental illness stigma, educational and contact intervention strategies can help improve college students' understanding of relevant knowledge, and cannot improve the level of implicit stigma of college students on mental illness.

Objective: To discuss possible ethical and boundary issues when contacting clients through WeChat in different situations. Methods: Self-made questionnaires were utilized to investigate 194 counselors' (18 counselors gave clients their job WeChat ID, 64 counselors gave their private WeChat ID, and 115 counselors do not give WeChat toclients) attitudes and behaviors of encountering multiple relationship issues when using WeChat Results: For WeChat boundary, counselors who had job WeChat ID would post more private photos and videos on the post than counselors with no job ID and without ID(P <0.01). Although 41％ of counselors would use WeChat during the counseling and other related activities, only 10％ of the counselors had job ID. Counselors with no ID tended to accept clients breaking the boundaries through other ways (P <0.01). Conclusion: The study indicates that counselors have encountered ethic issues of multiple relationships when using WeChat Counselors who only have private WeChat ID should increase their sensitivity of the boundary issues in the use of WeChat.

Objective: To explore school counselors' attitude and decision-making towards dual relationship and confidentiality. Methods: Totally 123 school counselors (27 males and 96 females, aged 20 to 60 years old, 41 primary and secondary counselors, 82 college counselors) filled up of self-designed Questionnaire for School Psychological Consultants on Dual Relationship and Confidentiality Rules, and the related factors which could influence the school counselors' attitude and their decision-making in dual relationship and confidentiality in the counseling work. Results:Totally 71.5％ (n =88) school counselors chose not to accept other relationships with students after counseling, 14.6％ (n = 18) school counselors chose to accept other relationships with students after counseling. The school counselors who had not accepted supervisioneasier to answer as "accept other relationship may raise clients self-esteem or feelings" than those had got supervision (P <0.05). The school counselor believed that the confidentiality agreement should be breached of the top 3(suicide attention, drug use and bad gangs). Counselors easier to breach confidentiality agreements on situation of students had suicide plans than situation of students had plans to run away from home(P <0.001). Conclusion:This study shows that two factors, including supervision and differential clients "issue may have effect on school counselors" attitudes and decision-making towards dual relationship and confidentiality situation in their counseling practice.

Objective:To investigate the impact of China's Mental Health Law on the work of psychological counseling in colleges and universities, and to explore ways to improve the law. Methods: Totally 12 heads of college and university counseling centers in Beijing were conducted with semi-structured interviews. The average age of the interviewees was (40 ±7) years old, with master or doctor degrees in psychology or related disciplines. The method of content analysis was used to analyze the interviewees' understanding of the " Mental Health Law". Results: All of the 12 interviewees had gained some understanding of the "Mental Health Law", and accordingly amended the regulation of their counseling centers. Also, interviewees suggested the positive and negative impacts brought by the law, such as enhancing practitioners' legislative sense, clarifying their responsibilities and boundaries as college and university counseling, as well as difficulties to distinguish psychotherapy and psychological counseling, ambiguity in the legality of working with students who were diagnosed with mental disorders. Moreover, interviewees threw out suggestions on improving the law from the aspect of industry standard, supervision department and vocational qualification. Conclusion: The execution of "Mental Health Law" improves practitioners' legislative sense, clarifies their responsibility. Nevertheless, it does not clearly distinguish psychotherapy from psychological counseling, and be lack of regulation on the psychological counseling industry.

Objective: To investigate the ethical decision-making process of breaking confidentiality when counselors dealing with self-inflicted injury and suicide issues in college situation. Methods: A semi-structural interview was addressed to 10 counselors from 7 college counseling centers in Beijing, among whom with (10 ± 8) years of experience on average in this field. Content analysis method was used to transcription of the interviewing data. Results: Totally 8 counselors had received ethical training more or less, and attached great importance to ethical codes. There were still some conflicts between school regulations and confidentiality rules in 7 university counseling centers. Different counselors varied greatly in decision-making on breaking confidentiality when facing college students' self-inflicted injury and suicide. Faced with conflicts between college demands and confidentiality principles, counselors could take the professional standpoint and consider more of the interests of students. Conclusion: The decision-making process on self-inflicted injury and suicide confidentiality breakthrough needs to be standardized. College's attention and support to the counseling work should be strengthen and enhance ethical awareness.

Objects:To investigate the current situation of counselors'implementation and their attitude to informed consent in Beijing.Methods:Eleven counselors who worked in Beijing were interviewed,the average of their working years was (7.4 ± 4.4).A semi-structured interview was used to learn about their practicing processes in and viewpoints on informed consent,and their interview transcripts were analyzed through qualitative method.Results:The results could be categorized into four categories,including the content of informed consent,the influential factors of informed consent,problems and confusions,and the significance of informed consent.The crucial role of informed consent in psychotherapy was generally recognized by counselors,and they could obey the related rules as well.The therapists had some confusion and problems about informed consent,such as the form and length,the consent for special population and online consultation.Conclusion:Basically,the counselors in Beijing could comply with the ethical standards of informed consent.However,they also suggest that certain limitations of these rules should be noticed.
