The ethical review of clinical research involving mental disorders in the ethical governance of scientific and technological has obvious particularities， especially in the field of artificial intelligence and brain-computer interfaces which are reflected in the impact on mental autonomy， the impaired informed consent ability of participants with severe mental disorders in research， and other aspects. In addition， the stigma of illness， the use of placebo， and psychological assessment methods in clinical research have also drawn attention to the ethical review of psychiatry. In 2020， the Beijing Municipal Health Commission issued the Guidelines for Ethical Review of Clinical Research Involving Mental Disorders （Guidelines）. Shen Yucun’s Psychiatry， compiled in 2023， revised the application of the Guidelines in the context of ethical governance. An analysis was conducted on the purpose and significance of its issuance and revision， its scope of application， the principal responsibility of ethical review in medical and health institutions， and the key content of ethical review in psychiatry， to improve the quality of ethical review in clinical research involving mental disorders and promote the standardized development of clinical research in psychiatry.

AIM: To explore the diagnostic value of 18 MHz color Doppler ultrasonography for epiretinal membrane.METHODS: A total of 44 cases(80 eyes)of patients with proposed diagnosis of cataract and vitreous opacity by fundus examination in our hospital between January 2020 and January 2022 were collected, and the affected eyes were examined by optical coherence tomography(OCT)and 18 MHz color Doppler ultrasonography, and the differences in the diagnostic sensitivity, specificity, and accuracy were compared between 18 MHz color Doppler ultrasonography and OCT for the diagnosis of epiretinal membrane.RESULTS: In the 80 eyes detected by 18 MHz color Doppler ultrasonography, 62 had epiretinal membrane and 18 had non epiretinal membrane. Totally 54 eyes were confirmed to have epiretinal membrane by OCT, 13 eyes were not diagnosed with epiretinal membrane, 5 eyes were missed diagnosis, and 8 eyes were misdiagnosed. The diagnostic consistency between 18 MHz color Doppler ultrasonography and OCT was high(Kappa=0.892, P<0.05); the 18 MHz color Doppler ultrasonography detection sensitivity of epiretinal membrane was 92%, specificity was 62%, missed diagnosis rate was 8%, misdiagnosis rate was 38%, and accuracy was 84%; compared with OCT detection, 18 MHz color Doppler ultrasonography detected a lower specificity, correct rate, positive prediction accuracy, negative prediction accuracy, and higher misdiagnosis rate(all P<0.05), and the difference in diagnostic sensitivity compared with leakage rate was not statistically significant(all P>0.05).CONCLUSION: 18 MHz color Doppler ultrasonography has some value in identifying epiretinal membrane lesions and is consistent with OCT testing.

Focal choroidal excavation(FCE)is an elusive clinical sign characterized by a localized structural depression in the choroid. It has been increasingly recognized with the widespread use of optical coherence tomography(OCT), though its pathogenesis remains incompletely understood and may involve congenital developmental anomalies or acquired factors(such as inflammation or tumor compression). Studies indicate that FCE can occur independently or secondary to various chorioretinal diseases(e.g., central serous chorioretinopathy, choroidal osteoma, age-related macular degeneration, etc.). Clinically, it has also been observed that FCE may be associated with the development of choroidal neovascularization(CNV). Potential mechanisms linking FCE and CNV include: 1)mechanical traction-hypoxia-signaling pathway activation; 2)disruption of the retinal pigment epithelium(RPE)-Bruch's membrane-choroid complex barrier; 3)structural collapse induced by inflammatory scar contraction. Anti-vascular endothelial growth factor(VEGF)therapy is currently the mainstay of treatment for CNV secondary to FCE. By reviewing relevant domestic and international literature, this paper seeks to elucidate the possible pathological relationship between FCE and CNV, with the goal of facilitating early identification of high-risk patients and optimizing anti-VEGF treatment strategies. It also highlights the limitations of current research(such as sample heterogeneity and lack of histological validation of typing criteria), and suggests future directions, such as multicenter studies and molecular mechanism investigations, to support the development of personalized diagnostic and therapeutic approaches.

Insufficient future liver remnant volume remains a critical limitation for single-stage resection in patients with hepatic malignancies. The techniques for promoting future liver remnant hypertrophy to realize two-stage hepatectomy include portal vein embolization， associating liver partition and portal vein ligation for staged hepatectomy， and portal vein ligation. In recent years， the application of auxiliary liver transplantation has further facilitated two-stage total hepatectomy. This article systematically reviews the clinical applications of these techniques and analyzes their advantages and limitations， so as to provide a reference for optimizing clinical decision-making.

Objective:This study aimed to explore the status of radiological Kashin-Beck disease (KBD) among school-aged children in Chamdo City, Tibet, through a 3-year monitoring survey, providing epidemiological evidence for prevention and control strategies.Methods:The target areas for this study were Luolong, Bianba, and Basu counties in Chamdo City, Tibet Autonomous Region, identified as having the most severe historical cases of KBD. Children aged 7-12 years attending school were enrolled as study subjects. Anteroposterior X-ray films of the right-hand were taken, and radiological diagnoses were made based on the "Diagnosis of Kashin-Beck Disease" criteria (WS/T 207-2010). Two experienced researchers independently reviewed the X-rays, and intra- and inter-group consistency were assessed using weighted Kappa values and percentage agreement. Cross-sectional surveys were conducted in 2017 and 2020 to describe the X-ray detection rates of KBD, and logistic regression analysis was employed to construct a predictive model of risk factors for radiological KBD cases.Results:In 2017, a total of 5,711 children aged 7-12 years in Chamdo City, Tibet, participated in the baseline cross-sectional survey (average age 9.2 years, 48.0% female), with 28 cases of radiological KBD. The age- and gender-standardized prevalence rate was 0.527%. In 2020, 6,771 participants (average age 9.3 years, 49.5% female) underwent a second cross-sectional survey, with 9 cases of radiological KBD and a standardized prevalence rate of 0.134%. Logistic regression analysis indicated that older age [ OR=2.439, 95% CI(1.299, 4.580), P=0.006] and female gender [ OR=8.157, 95% CI(1.016, 65.528), P=0.048] were independent risk factors for radiological KBD cases. Conversely, higher residential altitude, under the premise of Tibet's high altitude, was a protective factor [ OR=0.995, 95% CI(0.990, 0.999), P=0.032). Conclusion:The radiographically positive detection rate of KBD among school-aged children in Chamdo City, Tibet Autonomous Region, is at an extremely low level and showing a declining trend, reaching the historical standard in 2020. Considering the absence of positive signs in affected children, it suggests that local KBD has been effectively eliminated.

【Objective】 To construct a nomogram survival prediction model for patients with locally advanced renal cell carcinoma based on SEER database (n=7893), so as to provide reference for future prognosis study. 【Methods】 Case data were downloaded from the SEER database, and divided into the experimental group and validation group with a ratio of 7∶3 by simple randomization.The clinical information was analyzed, independent risk factors influencing prognosis were screened, and the overall survival (OS) and tumor-specific survival (CSS) were mapped.Model performance was evaluated using consistency index, area under the receiver operating characteristic curve (AUC), internal and external validation, and calibration curves. 【Results】 Patients’ age, tumor size, disease progression tpye, TNM stage, number of positive lymph nodes, marital status and pathological type were significantly correlated with OS and CSS (P<0.01).Based on the above predictors, the internal verification AUC of the 1-, 3- and 5- year OS nomogram model was 0.809, 0.721 and 0.715, respectively.The internal validation AUC of the nomogram model for 1-, 3- and 5- year CSS was 0.802, 0.745 and 0.735, respectively.The external validation AUC of the OS nomogram model was 0.792, 0.628 and 0.620 at 1, 3 and 5 years, respectively, and the external validation AUC of CSS was 0.943, 0.803 and 0.737 at 1.3 and 5 years, respectively, showing good model differentiation and accuracy. 【Conclusion】 The prediction performance of the nomogram model is good, and it can provide reference for individualized treatment.

Background The incidence of mental disorders is steadily increasing.However,antipsychotic medications,commonly used in treatment,can lead to drug-induced amenorrhea in female patients.This side effect significantly reduces medication adherence and increases the risk of disease recurrence.Therefore,addressing drug-induced amenorrhea in female patients has become an urgent problem requiring effective solutions.Objective To explore the efficacy and safety of traditional Chinese medicine compound in treating antipsychotic-induced amenorrhea,so as to provide guidance for the treatment of this condition using traditional Chinese medicine compound.Methods On September 4,2022,a computerized search was conducted on across multiple databases,including China National Knowledge Infrastructure,VIP Database,Wanfang Database,China Biomedical Literature Database,PubMed,Cochrane Library and Embase,and randomized controlled trials(RCT)of traditional Chinese medicine compound in treating antipsychotic-induced amenorrhea were collected.The quality of the included literature was assessed using Cochrane 5.3 bias risk assessment tool.Meta-analysis was performed to assess the total effective rate,cure rate,incidence of adverse reactions and recurrence rate using RevMan 5.3.Results Ultimately,22 RCT involving 1879 patients were included.Meta-analysis results showed that the total effective rate(RR=1.29,95%CI:1.16～1.44)and cure rate(RR=1.62,95%CI:1.45～1.80)of traditional Chinese medicine compound or its combination with western medicine in treating antipsychotic-induced amenorrhea were significantly higher compared to western medicine alone.Moreover,the incidence of adverse reactions(RR=0.56,95%CI:0.41～0.76)and recurrence rate(RR=0.16,95%CI:0.06～0.42)were significantly lower than those of western medicine alone.Conclusion Traditional Chinese medicine compound may offer benefits in ameliorating antipsychotic-induced amenorrhea and its safety is better than simple western medicine treatment.

Objective:To analyze the risk factors for central lymph node metastasis (CLNM) in patients with papillary thyroid cancer (PTC) aged 55 years and above, and to construct a predictive model with columnar graph.Methods:This retrospective study included 406 PTC patients aged 55 and above, treated at the First Affiliated Hospital of Zhengzhou University from Nov. 2019 to Feb. 2022. Data on demographic characteristics, disease features, and laboratory test results were collected. Univariate and multivariate logistic regression analyses were used to identify risk factors for CLNM and develop a clinical prediction model and nomogram.Results:The study involved 406 patients, divided into a modeling group (285 patients) and a validation group (121 patients). The predictive model identified independent risk factors for CLNM. In the modeling group, the model demonstrated a ROC AUC of 0.769, with 82.6% sensitivity, 63.0% specificity, and 67.7% accuracy. The validation group showed 66.7% sensitivity, 74.5% specificity, and 72.7% accuracy, with an AUC of 0.760. Hosmer-Lemeshow tests indicated good fit in both groups. Decision curve analysis confirmed the model's clinical decision-making value, showing better performance than traditional strategies and good generalizability and reliability.Conclusions:Sex, maximum tumor diameter, bilateral involvement of thyroid lobes, clinically evident cervical lymph nodes, and local invasion are independent predictive factors for CLNM in patients over 55 with papillary thyroid carcinoma (PTC). A clinical risk stratification nomogram model based on these risk factors demonstrates good predictive performance.

Objective To explore the application of serum signal transducers and activators of transduction 3(STAT3)and SMAD4 expression levels in the early diagnosis and clinical staging of primary glaucoma patients.Methods 86 patients with primary glaucoma admitted to Cangzhou Eye Hospital from August 2021 to May 2023 were selected as the study group,according to the clinical symptoms and visual examination results of the research group,they were divided into mild injury stage(n=30),moderate injury stage(n=34)and severe injury stage(n=22).Another 86 healthy individuals who underwent physical examinations in Cangzhou Eye Hospital during the same period were collected as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to detect the expression levels of serum STAT3 and SMAD4.Multivariate Logistic regression was applied to analyze the relevant factors affecting clinical staging of primary glaucoma,receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum STAT3 and SMAD4 in patients with moderate/severe primary glaucoma injury.Results The expression levels of serum STAT3(13.96±3.45 ng/ml)and SMAD4(11.23±2.85 ng/ml)in the study group were obviously higher than those in the control group(9.83±1.72 ng/ml,7.78±1.95 ng/ml),the differences were statistically significant(F=13.085,17.513,all P＜0.05).The expression levels of serum STAT3(11.88±2.52 ng/ml,13.85±3.51 ng/ml,16.96±4.63 ng/ml)and SMAD4(9.15±1.95 ng/ml,11.23±2.83 ng/ml,14.08±4.12 ng/ml)in patients with primary glaucoma in mild,moderate and severe injury groups were gradually increased,the differences were statistically significant(F=13.085,17.513,all P＜0.05).There was a statistically obvious difference in intraocular pressure among patients with mild,moderate(24.21±5.03 mmHg,28.16±6.31 mmHg,32.26±7.57mmHg),and severe injuries(F=10.577.P＜0.05).serum STAT3[OR(95%CI)=2.728(1.409～5.281)],SMAD4[OR(95%CI)=2.849(1.507～5.387)],and intraocular pressure[OR(95%CI)=2.435(1.094～5.417)]were risk factors affecting clinical staging of primary glaucoma(all P＜0.05).The area under the curve(AUC)of the combined diagnosis of serum STAT3 and SMAD4 for moderate/severe injury in patients with primary glaucoma was 0.963(95%CI:0.899～0.992),which was superior to their respective individual diagnoses(Z =2.558,1.961;P=0.010,0.049),their sensitivity and specificity were 96.43%and 83.33%,respectively.Conclusion The higher the expression levels of STAT3 and SMAD4 in serum,the more severe the clinical symptoms in patients.The combined detection of the two has good diagnostic value for patients with moderate/severe injury.
