ObjectiveTo explore the current situation of forensic ethics practice and education by designing a questionnaire on forensic ethics， with a view to exploring the path of forensic ethics education construction. MethodsA total of 667 valid questionnaires were collected using the online survey method， basically covering various regions across the country and all sub-specialties of forensic medicine. Descriptive analysis was used to analyze the relevant data. ResultsMost practitioners had relevant ethical reflections in the process of forensic practice. 69.12% of the respondents indicated that they had studied the relevant rules， but approximately half stated that there were no corresponding ethical norms or standard operating manuals. The specific behaviors violating ethics in different units were diverse. 23.04% of the respondents reported that they had encountered unethical behaviors， but only 4.9% of them reported such violations. In terms of forensic ethics education， 87.75% of the respondents believed that there were issues with the current model of forensic ethics education. Meanwhile， the respondents showed a high degree of recognition for receiving forensic ethics education， with 84.15% of respondents expressing willingness to participate in relevant courses. More than half of respondents were willing to participate in forensic ethics education during undergraduate studies， new employee training， and regular post-employment training. ConclusionCurrently， there is a problem of ethical neglect in forensic work in China. Combining ethics courses with professional courses at the practitioner training stage and providing regular training at the practice stage are effective measures to popularize forensic ethics knowledge， enhance ethical awareness， and improve the quality of practice.

Background/Aims: Liver transplantation is the most effective treatment for the sickest patients with acute-on-chronic liver failure (ACLF). However, the influence of donor age on liver transplantation, especially in ACLF patients, is still unclear. Methods: In this study, we used the data of the Scientific Registry of Transplant Recipients. We included patients with ACLF who received liver transplantation from January 1, 2007, to December 31, 2017, and the total number was 13,857. We allocated the ACLF recipients by age intogroup I (donor age ≤17 years, n=647); group II (donor age 18–59 years, n=11,423); and group III (donor age ≥60 years, n=1,787). Overall survival (OS), graft survival, and mortality were com-pared among the three age groups and the four ACLF grades. Cox regression was also analyzed. Results: The 1-, 3-, and 5-year OS rates were 89.6%, 85.5%, and 82.0% in group I; 89.4%, 83.4%, and 78.2% in group II; and 86.8%, 78.4%, and 71.4% in group III, respectively (p<0.001).When we analyzed the different effects of donor age on OS with different ACLF grades, in groupsII and III, we observed statistical differences. Finally, the cubic spline curve told us that the relative death rate changed linearly with increasing donor age. Conclusions Donor age is related to OS and graft survival of ACLF patients after transplanta-tion, and poorer results were associated with elderly donors. In addition, different donor ages have different effects on recipients with different ACLF grades.

As a common pathological state in clinical practice， Chong Mai Wei Bing （冲脉为病） is typically manifested as rebellious qi and a sense of urgency. It often involves various diseases caused by the disorder of qi circulation. From the perspectives of theoretical foundation， pathological characteristics， and clinical differentiation and treatment， this paper elaborates on the characteristics of Chong Mai （冲脉） as the cause of disease， including three main manifestations： upward qi surge， upward yin fire， and upward water-qi. Among these， the upward qi surge is further categorized into four aspects： Chong Qi （冲气） counterflow， counterflow of stomach qi， counterflow of kidney qi， and counterflow of liver qi. Three major treatment methods are proposed： pacifying the Chong Mai and reversing the counterflow， consolidating Chong Mai to subdue fire， and warming Chong Mai to resolve qi and promote water flow. This paper summarizes its practical application in clinical diagnosis and treatment， aiming to deepen the understanding of the functional and pathological mechanisms of Chong Mai， and to provide insights and methods for the traditional Chinese medicine diagnosis and treatment of various diseases.

Objective To investigate the effect of teaching method using students as standardized patients on clinical practice teaching of neurology.Methods We randomly assigned 80 undergraduate majoring in clinical medicine into two groups:a control group where students were instructed with traditional clinical teaching methods,and an experimental group where students acted as standardized patients.Following the clinical placement,we administered an Objective Structured Clinical Exam-ination(OSCE)and a satisfaction survey to all participants.Results The experimental group performed significantly better than the control group in history taking and neurological examination in the OSCE(P＜0.05).The results of the questionnaire showed that the experimental group scored significantly higher than the control group in improving clinical thinking,stimulating learning interest,and improving communication skills(P＜0.05).Conclusion The teaching methods using student as standardized pa-tients in the process of clinical practice in neurology helps to improve the history taking and neurological physical examination skills of clinical students,yielding good educational outcomes.

Objective To evaluate the clinical effect of Tension-free laparoscopic lateral suspension with mesh for pelvic organ prolapse.Methods A total of 85 patients who underwent pelvic organ prolapse were selected as the study group,and 40 patients underwent Laparoscopic sacral fixation surgery(LSC)as the control group in Henan Provincial People's Hospital from March 1,2021 to October 31,2023.The patients were divided into two subgroups:uterine preservation group and uterine resection group and followed up until April 30,2024.The intra-operative conditions and postoperative complications were recorded and analyzed.POP quantitative staging(POP-Q)scores were used for evaluation.Preoperative and postoperative quality of life and therapeutic effect were evaluated using the pelvic floor distress inventory short form-20(PFDI-20),urinary distress inventory-6(UDI-6),colorectal-anal distress inventory-8(CRADI-8),pelvic organ prolapse distress inventory-6(POPDI-6),pelvic floor impact questionnaire-7(PFIQ-7),prolapse and Incontinence sexual function questionnaire short form(PISQ-12).Results The median follow-up time for patients in the study group is 13.13 months,with an objective cure rate of 96.47%and a reoperation rate of 1.18%.The perioperative complication rates are 6.45%for uterine resection and 4.35%for uterine preservation,while the mesh exposure rate is 1.61%for uterine resection.In comparison,the median follow-up time for patients in the control group is slightly longer at 13.76 months,with an objective cure rate of 92.5%and a reoperation rate of 2.5%.The perioperative complication rates are higher at 14.71%for uterine resection and as high as 33.33%for uterine preservation,while the mesh exposure rate is also elevated at 8.82%for uterine resection.Despite these differences,there was no significant disparity in objective cure rates or reoperation rates between the study group and the control group.Furthermore,it was observed that the study group experienced shorter operation times,less bleeding,faster postoperative recovery,shorter hospitalization periods,lower perioperative complications,and reduced mesh exposure rates-especially among patients with uterine preservation.Additionally,intra-group comparisons revealed significant improvements in all POP-Q indicators one year after surgery(P<0.05),along with significantly lower scores on PFDI-20,UDI-6,CRADI-8,POPDI-6,PFIQ-7,and PISQ-12 scales com-pared to pre-surgery levels(P<0.05).However,no significant inter-group differences were noted.Conclusions Tension-free laparoscopic lateral suspension with mesh proves to be an effective surgical approach for treating ante-riorand middle pelvic organ prolapse.It demonstrates few perioperative complications while significantly improving prolapse symptoms and enhancing patient qualityof life.It stands as a viable alternative to sacrocolpopexy,particu-larly beneficial for patients with a preserved uterus.

Objective To retrospectively explore the diagnosis and treatment of severe immune thrombocytopenia(SIT)induced by programmed death-1(PD-1)monoclonal antibody.Methods Three patients with SIT caused by PD-1 monoclonal antibody treatment at Putuo District People's Hospital,Zhoushan City,Zhejiang Province from March 2020 to October 2022 were selected,and the diagnosis and treatment process and disease outcome were analyzed.Results All three patients were diagnosed with malignant tumors after postoperative pathological examination,and SIT was induced after PD-1 monoclonal antibody treatment,of which one patient died,and two patients improved after the treatment.Conclusion PD-1 induced SIT often occurs after 12 weeks,and clinical diagnosis can be confirmed by combining patients'medication history,platelet antibodies,and bone marrow examination.In terms of treatment,combination therapy such as ordered reduction of hormones,thrombopoietin,and platelet receptor agonists can promote the recovery of the patient.In addition,if necessary,CD20 monoclonal antibody therapy can be applied to antagonize platelet antibodies.

ObjectiveTo investigate the effect and mechanism of Zhenwutang on renal oxidative damage in the mouse model of diabetic kidney disease with the syndrome of spleen-kidney Yang deficiency via the nuclear factor erythroid 2-related factor-2 （Nrf2）/heme oxygenase-1 （HO-1）/glutathione peroxidase 4 （GPX4） signaling pathway. MethodTwenty-five 7-week-old SPF-grade male db/m mice and 95 7-week-old SPF-grade male db/db mice were adaptively fed for a week. A blank group was set with the db/m mice without treatment， and the other mice were administrated with Rhei Radix et Rhizoma decoction and hydrocortisone for the modeling of diabetic kidney disease with the syndrome of spleen-kidney Yang deficiency. The modeled mice were randomized into the model， irbesartan （25 mg·kg^-1）， and high-， medium-， low-dose （33.8， 16.9， 8.45 g·kg^-1） Zhenwutang groups （n=15） and administrated with corresponding drugs for 8 weeks. The survival status of mice was observed， and the traditional Chinese medicine （TCM） syndrome score was recorded. The indicators related to spleen-kidney Yang deficiency， fasting blood glucose （FBG）， and renal function indicators were determined. Hematoxylin-eosin staining was employed to observe the histopathological changes of the renal tissue in each group. Biochemical kits were used to determine the oxidative stress-related indicators in the renal tissue. Real-time polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels， respectively， of Nrf2， HO-1， glutamate-cysteine ligase catalytic subunit （GCLC）， and GPX4 in the renal tissue of mice in each group. ResultCompared with the blank group， the modeling increased the TCM syndrome score （P<0.05）， elevated the estradiol （E₂） and FBG levels （P<0.05）， lowered the testosterone （T）， triiodothyronine （T3）， and tetraiodothyronine （T4） levels （P<0.05）， and weakened the renal function （P<0.05）. In addition， the modeling led to glomerular hypertrophy and glomerular mesangial and basal thickening， decreased the catalase （CAT） activity， total antioxidant capacity （T-AOC）， and glutathione （GSH） content （P<0.05）， increased the malondialdehyde （MDA） content （P<0.05）， and down-regulated the mRNA and protein levels of Nrf2， HO-1， GCLC， and GPX4 in the renal tissue （P<0.05）. Compared with the model group， high and medium doses of Zhenwutang decreased the TCM syndrome score and E₂ content （P<0.05）， increased the T， T3， and T4 content （P<0.05）， improved the renal function （P<0.05）， alleviated the pathological changes in the renal tissue， increased CAT， T-AOC， and GSH （P<0.05）， reduced MDA （P<0.05）， and up-regulated the mRNA and protein levels of Nrf2， HO-1， GCLC， and GPX4 in the renal tissue （P<0.05）. ConclusionZhenwutang can improve the general state and renal function and reduce the oxidative damage and pathological changes in the renal tissue of db/db mice with spleen-kidney Yang deficiency by regulating the Nrf2/HO-1/GPX4 signaling pathway.
