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.

Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

ObjectiveTo understand the status of parasitic infection in the food sold on market in Qingpu District of Shanghai, and to provide an evidence for the development of prevention and control strategies for parasitic infection applicable to Qingpu District. MethodsAquatic products, meat products and other foodstuffs sold on online shops, at farm product markets, supermarkets/foodstores and restaurants were sampled in Qingpu District, Shanghai, during 2015‒2023, based on the administrative division of Qingpu District. The parasitic infection in the food samples were examined using pressing method and digestion for detecting metacercariae in freshwater products and pickled products, using dissection microscopy for Anisakis larvae in seawater products, Taenia cysticercus and Trichinella encysted larvae in meat products. ResultsA total of 1 079 samples of food products were examined during 2015‒2023, with a total parasite infection rate of 13.44%. The total parasite infection rate of freshwater fish products was 3.40% (16/471), and the difference of parasite infection rates between different freshwater fish species was statistically significant (χ²=229.609, P=0.001). The total infection rate of Clonorchis sinensis was 3.18% (15/471), which had been detected in Pseudorasbora parva, Cyprinidae rhodeus, and Carassius auratus, with a positive rate of 77.78% (7/9), 50.00% (5/10) and 3.90% (3/77), respectively. Metorchis orientalis was detected in in Pseudorasbora parva, with a positive rate of 33.33% (3/9). The positive rate of Gnathostoma spinigerum (third-stage larvae) was 0.81%. Paragonimus metacercariae were not detected in the freshwater shrimps and crabs. The infection rate of seawater fish products was 26.46%. The difference of parasite infection rate in seawater fishes was statistically significant (χ²=109.181, P=0.001). A total of 53 pork and beef samples were tested, none was detected with Trichinella larva cysts, Taenia solium metacercariae, and Taenia saginata metacercariae. The total infection rate of pickled yellow mud snail products was 58.11% (43/74). Paragonimus metacercariae was not detected in any of the pickled aquatic product samples. ConclusionThere are different degrees of parasitic infection in freshwater products, seawater products and pickled aquatic products in Qingpu District of Shanghai. The risk of parasite infection from raw or undercooked foods is high. Health education on healthy dietary practices such as throughly cooked food should be strengthened for local residents.

Objective: To investigate the effects of different storage temperatures and durations on the activities of coagulation factor Ⅷ (Factor Ⅷ, FⅧ) and coagulation factor Ⅸ (Factor Ⅸ, FⅨ) after whole blood collection, so as to provide data support for the optimal storage conditions. Methods: A total of 16 mL of whole blood was collected from each of the 20 healthy volunteers at our blood center and aliquoted into 8 sodium citrate anticoagulant tubes. Two tubes were immediately centrifuged for the measurement of FⅧ and FⅨ activity levels. The remaining 6 tubes of whole blood were respectively stored under room temperature and low-temperature conditions. At 2, 4, and 6 h, the whole blood samples were centrifuged and analyzed for FⅧ and FⅨ activity levels. The mean values of the two immediately tested tubes were used as the control group, while other tubes were designated as the experimental groups for comparison. Statistical analysis was performed using SPSS 26.0. Results: The activity of FⅧ in whole blood remained stable after 4 hours of storage at both room temperature and low temperature (116.53±25.95 vs 125.22±27.33, 109.77±23.23 vs 125.22±27.33) (P>0.05 for both). However, by 6 hours, FⅧ activity showed a statistically significant decline compared to the control group (108.65±22.92 vs 125.22±27.33, 100.46±20.19 vs 125.22±27.33) (P<0.05 for both), though the room temperature group results were closer to the control values. The activity of FⅨ in whole blood remained stable after 6 hours of storage under both conditions (97.14±19.48 vs 96.76±19.67, 97.10±17.45 vs 96.76±19.6) (P>0.05 for all comparisons). Conclusion: For whole blood samples after collection, storage at either room temperature or low temperature for up to 4 hours does not compromise the accuracy of test results. When stored for 6 hours, FⅨ activity remains stable, whereas FⅧ activity decreases significantly. Notably, FⅧ activity demonstrates better stability at room temperature than under low-temperature conditions within the 6-hour storage.

Chronic heart failure （CHF） is the terminal stage of various heart diseases， with high morbidity， mortality， and hospitalization rate. According to the theory of collateral diseases， the core pathogenesis of CHF is blood stasis of collaterals， water retention and stagnation， and pathogen accumulation in collaterals. Accordingly， the treatment should focus on reinforcing healthy Qi to warm Yang， activating blood to dredge collaterals， and excreting water to alleviate edema. On this basis， Qili Qiangxin capsules （QLQX） are created. This prescription can effectively treat chronic heart failure. Modern studies have shown that QLQX contains a variety of pharmacological components such as flavonoids， alkaloids， terpenoids， phenylpropanoids， phenolic acids， and cardiac glycosides. QLQX can improve the cardiac function， inhibit myocardial fibrosis， improve hemodynamics， mitigate inflammation， reduce cardiomyocyte apoptosis， and regulate the nervous system， with mild adverse reactions. This study analyzed the etiology and pathogenesis of CHF based on the theory of collateral diseases， explored the relationship between the prescription and syndrome， and delved into the material basis and mechanism of QLQX in the treatment of CHF， aiming to provide reference for the clinical application and scientific research of QLQX.

Objective: To study the correlation between activated partial thromboplastin time (APTT) mixing test results and the inhibitor titers in hemophilia A inhibitor-positive patients. Methods: In this cross-sectional study, 41 patients with severe hemophilia A and inhibitors (and negative for lupus anticoagulant) were included from the hemophilia clinic of Shandong Blood Center from February 2022 to February 2024. All patients underwent APTT mixing test. The Rosner's index (RI, including the immediate RI and the RI after 2-hour water bath incubation [water bath 2h RI]), the time-dependent difference (Δ value), and the corrected percentage were calculated based on results of APTT mixing test. The median (interquartile range) of the corresponding indexes were calculated, and the ROC curves for identification of high inhibitor titers using the four indexes (the immediate RI, the water bath 2h RI, the Δ value, and the corrected percentage) were plotted, The correlations between APTT mixing test and inhibitor titers for coagulation factor Ⅷ (Factor Ⅷ, FⅧ) were investigated. Results: The median (lower quartile, upper quartile) of immediate RI, water bath 2h RI, Δ-value and corrected percentage for FⅧ inhibitor positive patients were 11.0 (5.4, 29.3)%, 45.0 (25.7, 75.0)%, 26.2 (7.6, 41.8) s, and 82.2 (58.5, 91.6)%, respectively. The median (lower quartile, upper quartile) of the immediate RI, water bath 2h RI, Δ-value and corrected percentage were 25.2 (13.0, 37.5)%, 64.1 (44.6, 72.6)%, 38.0 (14.3, 38.3) s, and 66.5 (50.1, 82.1)% for the high-titer inhibitor group, and 5.2 (4.2, 9.4)%, 17.9 (8.8, 28.0)%, 13.0 (7.6, 25.4) s, and 92.3 (88.0, 94.3)% for the low-titer inhibitor group. The AUCs of the ROC curves for discrimination between high and low titer inhibitor were: 0.9105 for immediate RI, 0.9118 for water bath 2h RI, 0.8873 for correcter percentage, and 0.6532 for Δ-value. Conclusion: High-titer inhibitors can be highly suspected in hemophiliac patients with an immediate RI >10% and a water bath 2h RI >45%, and the presence of low-titer inhibitors is suspected in patients with a 4-second < immediate RI <10% and a 13% < water bath 2h RI <45%.

On-site supervision is a risk-based regulatory system that requires the scientific development of supervision plans for quality risks and hidden dangers in pharmaceutical enterprises， the rational allocation of supervision resources based on their risk levels， and the implementation of classified supervision measures. In this study， the quality risk monitoring business support system is set up for pharmaceutical enterprises by establishing the quality risk expert database and quality risk monitoring index system for pharmaceutical enterprises based on the difficulty analysis of on-site drug supervision. Based on this support system， the quality risk classification method， the differentiated spot check strategy and business auxiliary visualization system are established. This support system is used to learn the risk level of pharmaceutical enterprises， so as to innovate supervision methods and optimize monitoring strategies. Taking Jiangxi Province as an example， it is verified that the support system can guide the risk assessment of sample enterprises， can improve the targeting of on-site drug supervision in the process of technical review， scheme editing， on-site implementation and comprehensive evaluation， and can effectively improve the quality and efficiency of supervision.

AIM:To explore the protective effect of Xiaoxuming decoction(XXMD)on synaptic plasticity in the context of cerebral ischemia-reperfusion injury following ischemic stroke.METHODS:An oxygen-glucose depriva-tion/reoxygenation(OGD/R)model was employed in vitro using mouse hippocampal neurons(HT22 cells)to simulate ischemia-reperfusion injury.Cell viability was assessed using a CCK-8 assay to determine the optimal XXMD concentra-tion.The HT22 cells were divided into two groups:control and model(OGD/R).Cellular morphological changes were ob-served using an inverted microscope.The levels of IL-1β,IL-6 and TNF-α in the supernatant were quantified by ELISA.Ultrastructural changes were examined by transmission electron microscopy.Immunofluorescence staining was used to de-tect neuron markers NeuN and synaptic proteins NF200 and MAP2.The protein levels of NF200 and MAP2 were analyzed by Western blot.RESULTS:The highest cell survival rate occurred at an XXMD concentration of 100 mg/L(P<0.05).Compared with control group,the cells in model group exhibited round shape and shrinkage,mitochondrial swelling or vacuolization,and a marked decrease in survival rate.There were significant increases in IL-1β,IL-6 and TNF-α levels(P<0.05).Immunofluorescence intensity and protein levels of NeuN,NF200 and MAP2 were notably reduced(P<0.05).Treatment with XXMD improved cell morphology,ultrastructure and survival rate(P<0.05),and decreased in-flammatory factor levels(P<0.05).Compared with model group,the cells in OGD/R+XXMD group showed significantly increased immunofluorescence intensity and protein levels of NeuN,NF200 and MAP2(P<0.05).CONCLUSION:Xiaoxuming decoction may mitigate OGD/R-induced injury,potentially by inhibiting inflammatory responses and enhanc-ing synaptic plasticity.

The rational use of medical insurance fund(MIF) plays an important role in promoting the high-quality development of public hospitals, and the supervision of MIF is in a trend of under the rule of law, normalization, professionalization and standardization, and unannounced inspection will become the norm. The authors systematically analyzed three main trends of MIF unannounced inspections, namely, gradually increasing intensity, constantly innovating methods, and increasingly serious consequences. The problems exposed in unannounced inspections were sorted out from five dimensions: form of results, severity, scope of attribution, subjective intention, and regulatory screening ideas. The enlightenment of MIF unannounced inspections to hospital management was explored from four aspects: compliance awareness, organizational system, fine management, and daily supervision. It was proposed that public hospitals should transform their roles and positions, improve the working mechanism of departmental collaboration, and achieve fine management in policy understanding, system formulation, process design, information support, data governance, regulatory implementation, personnel training, and performance matching. At the same time, internal simulated unannounced inspections in hospitals should be regarded as a routine work.
