Objective To investigate the expression of Cyclin F in clear cell renal cell carcinoma (ccRCC), its clinicopathological characteristics, and its effect on the biological behavior of renal cancer cell lines Methods RT-qPCR and Western blot were used to detect the mRNA and protein expression of Cyclin F in fresh ccRCC specimens. Immunohistochemistry assay was performed to detect the expression of Cyclin F protein in 80 paraffin samples. CCK-8 assay, scratch assay, and flow cytometry were conducted to determine the effects of Cyclin F overexpression on the proliferation, migration, and apoptosis of renal cancer cell lines. Results The expression of Cyclin F in cancer tissues was higher than that in adjacent tissues at the mRNA level (P<0.0285). The expression of Cyclin Fprotein in cancer tissues was lower than that in adjacent tissues (P<0.001). The analysis of clinicopathological parameters showed that the low expression of Cyclin F was correlated with WHO/ISUP grade, Ki67 index, and age (P=0.041, 0.047, 0.008,). In vitro experiments confirmed that overexpression of Cyclin F promoted the proliferation (P<0.001) and migratory ability (24 h P=0.003, 48 h P=0.0058) of the RCC 786-O cell line, while inhibiting apoptosis (P=0.0019). Conclusion The low expression of Cyclin F protein in ccRCC tissuesis associated with high ISUP grade, high Ki67 index, oldage, and prognosis of patients.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To elucidate the impact of chronic kidney disease(CKD)on the clinical outcomes of patients with left main coronary artery disease(LMCAD)undergoing intravascular ultrasound(IVUS)-guided percutaneous coronary intervention(PCI).Methods This retrospective study enrolled consecutive patients with LMCAD who underwent IVUS-guided PCI at Wuhan Asia Heart Hospital between January 2017 and December 2020.Patients were stratified into CKD and non-CKD groups according to the presence of CKD.Clinical data were systematically retrieved from the electronic health record system.Demographic,clinical,and angiographic characteristics were compared between groups.The primary endpoint was major adverse cardiovascular events(MACE),defined as a composite of all-cause mortality,myocardial infarction,and ischemic stroke.Results A total of 325 LMCAD patients[mean age(62.56±9.86)years;73.54％male]were included,with 31 patients(9.54％)in the CKD group.During a median follow-up of 5 years,CKD patients exhibited significantly older age[(70.13±9.77)years vs.(61.77±9.54)years,P＜0.001],higher prevalence of three-vessel disease(64.52％vs.38.10％;P=0.040)and left main bifurcation lesion(45.16％vs.37.76％,P=0.011),greater IVUS-detected calcification burden(P=0.029),and higher median SYNTAXⅡ scores[(34.10(30.30,39.25)vs.26.75(22.42,31.58),P＜0.001)].The cumulative incidence of MACE was significantly higher in the CKD group compared to the non-CKD group(32.26％vs.9.18％,P＜0.001).Univariate Cox regression analysis and Kaplan-Meier survival curves confirmed a 5.877-fold increased risk of MACE in CKD patients(95％CI 2.765-12.494).After adjusting for age and cardiac function,CKD remained an independent predictor of MACE(HR 3.611,95％CI 1.634-7.978).Conclusions LMCAD patients with concomitant CKD present with advanced age,impaired cardiac function,more extensive coronary disease,and severe calcification.The presence of CKD is associated with a significantly worse long-term prognosis.

Aim To investigate the role of triggering receptor expressed on myeloidcells 2(TREM2)in syn-aptic plasticity induced by cocaine addiction.Methods C57BL/6J mice and Trem2 knockout mice were uti-lized in this study to evaluate the alterations in postsyn-aptic density protein 95(PSD-95)and synapsin 1(SYN1)within the cortex and hippocampus of co-caine-addicted mice by using immunological tech-niques.Results HE staining and Nissl staining showed increased neuronal damage in the hippocampus and cortex of mice after cocaine addiction.The results of immunohistochemistry and fluorescence of PSD-95 and SYN1 were consistent with the expression trend of Western blot.In the wild type mouse model,the ex-pression level of PSD-95 in the hippocampus and cortex was lower than that in the saline group,and the ex-pression of SYN1 was higher than that in the saline group.In the knockout mouse model,the expression levels of PSD-95 and SYN1 in the hippocampus and cortex were significantly higher than those in the saline group after cocaine addiction.The expression levels of PSD-95 and SYN1 in the hippocampus and cortex of cocaine knockout mice were higher than those of co-caine wild type mice.Conclusion Cocaine addiction can change the synaptic plasticity,and TREM2 plays a regulatory role in the synaptic plasticity of hippocampus and cortex in mice with cocaine injury.TREM2 is ex-pected to be a new target for studying the mechanism of cocaine addiction.

Objective To explore the factors leading to early admission for delivery among low-risk and full-term primiparas from both the perspectives of pregnant women and healthcare professionals,and to formulate targeted interventions for reference in ameliorating early admission trend among these primiparas.Methods Using purposeful sampling,we enrolled 11 medical staff members and 13 pregnant women from the Department of Obstetrics,Obstetrics and Gynecology Hospital,Fudan University for semi-structured in-depth interviews.Content analysis was utilized to organize and analyze the collected data.Results From the perspective of pregnant women,the reasons were categorized into personal and environmental factors.Personal factors included cognition related to delivery and variability in the perception of labor contraction pain.Environmental factors included the difficulty in verifying the authenticity of labor-related information on the internet,the transmission of anxiety among family members,the convenience of obtaining medical resources,the lack of clear medical advice,and limited access to auxiliary equipment resources.From the perspective of healthcare professionals,the reasons were categorized into three aspects:factors related to pregnant women,i.e.,anxiety about delivery and fear of unknown pain during delivery;factors related to medical staff,i.e.,differences in medical practice and the provision of excessive information with insufficient pertinence in education;and objective factors,i.e.,primiparas were incapable of utilizing objective criteria to discern the start of delivery,and the convenience of accessing medical resources.Conclusion Factors leading to early admission for delivery among low-risk and full-term primiparas are personal factors,environmental factors,factors related to medical staff,and objective factors.To standardize the delivery admission timing,enhance prenatal health education,and develop outpatient support system will help assisting pregnant women in choosing an appropriate time for hospital admission.

Objective:To investigate the effect of sevoflurane combined with propofol general anesthesia on immune function and cognitive function in patients undergoing laparoscopic inguinal hernia repair.Methods:A total of 120 patients with laparoscopic inguinal hernia repair treated in Wuxi Ninth People's Hospital Affiliated to Soochow University from January 2021 to March 2022 were randomly divided into control group and observation group.They were operated under general anesthesia.Control group were given pro-pofol intravenous pump,and observation group were given sevoflurane combined inhalation+propofol intravenous pump.The vital signs(mean arterial pressure,heart rate),postoperative pain(VAS score),immune function[T cell subsets(CD3+T,CD4+T,CD8+T,CD4+T/CD8+T),IgG,IgA,IgM],cognitive function(MMSE score,incidence of cognitive impairment)and adverse reac-tions(nausea and vomiting,dizziness,drowsiness,respiratory depression and body movement)were observed.Results:The mean ar-terial pressure at 10 min after laryngeal mask implantation,at the beginning of operation and 10 min after laryngeal mask removal in the two groups were lower than that before anesthesia induction(P<0.05),the heart rate at the beginning of operation in the control group was lower than that before anesthesia induction(P<0.05),and the mean arterial pressure and heart rate in each time period in the two groups were similar(P>0.05);the VAS scores of the observation group were lower than those of the control group(P<0.05);The levels of CD3+T,CD4+T,CD4+T/CD8+T,IgG,IgA,IgM in the observation group were higher than those in the control group(P<0.05),and CD8+T was lower than those in the control group 1 day after operation(P<0.05);the MMSE score and the incidence of cog-nitive impairment were similar in the two groups 1 day after operation(P>0.05);the incidence of adverse reactions in the two groups were similar(P>0.05).Conclusion:Sevoflurane combined with propofol general anesthesia has a good effect in laparoscopic inguinal hernia repair.It can stabilize patients'intraoperative vital signs,reduce postoperative pain,improve immune function indexes,and does not increase the incidence of postoperative cognitive impairment and adverse reactions.

Aim To explore the effects of Kui Jie Kang(KJK)on modulating the farnesoid X receptor(FXR)pathway in the gut microbiota and bile acid metabolism in mice with ulcerative colitis(UC).Methods Mice were subjected to DSS-induced UC and randomly as-signed to the control(CON),model(MOD),and two KJK-dosed groups(KJK.H at 12.8 g·kg-1,KJK.L at 3.2 g·kg-1).Mouse body weight was recorded,and disease activity index(DAI)was scored.The his-topathological changes in colonic tissue were observed via HE staining,and the number of goblet cells and mucosal layer repair were assessed using PAS and Al-cian blue staining.Bile acid content in feces was measured using LC-MS/MS,gut microbiota composition was analyzed by 16S rRNA gene sequencing,and the expression of FXR target genes and related proteins was detected by RT-qPCR and Western blot.Results KJK significantly ameliorated colonic shortening,de-creased disease activity index in UC mice,reduced his-topathological scores,increased the number of goblet cells and mucus secretion,altered the levels of primary and secondary bile acids,and increased the relative a-bundance of beneficial bacteria such as Lactobacillus.Additionally,it significantly upregulated the expression of FXR and FGF15 mRNA and protein in colonic tissue and downregulated the expression of hepatic CYP7A1 mRNA,and the correlation analysis in this study clearly revealed a significant correlation between bile acid me-tabolism disorders and gut microbiota imbalance in UC.Conclusion KJK activates the intestinal FXR-FGF15-CYP7A1 pathway,thereby regulating bile acid metabolism and restoring gut microbiota balance,which may be key to its improvement of UC.

Objective:To conduct a scoping review of studies on the application of exercise interventions in the rehabilitation of patients with hemophilic arthropathy (HA) .Methods:A systematic search was conducted in PubMed, Web of Science, Cochrane Library, Embase, CINAHL, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc. The search period was from the database inception to March 1, 2024. Relevant literature was screened, summarized, and analyzed.Results:A total of 31 studies were included. The study population mainly consisted of adult patients with moderate to severe hemophilia suffering from elbow, knee, and ankle arthropathy, who were in a stable bleeding phase without coagulation factor inhibitors. Exercise types included resistance training, aerobic exercise, balance/proprioceptive exercises, and flexibility training. The exercise intensity was predominantly low to moderate. The duration of each session was mostly 30-60 minutes, with a frequency of 2-5 times per week and a total intervention period of 4-12 weeks. Exercises were mostly conducted in medical institutions under face-to-face supervision. Exercise interventions led to varying degrees of improvement in mobility, balance/proprioceptive function, joint function, cardiopulmonary fitness, psychological well-being, and quality of life.Conclusions:Exercise interventions for patients with hemophilic arthropathy are diverse, demonstrating safety, feasibility, and efficacy. Future research should focus on a multidisciplinary, exercise-centered rehabilitation approach, standardizing evaluation criteria, and dynamically monitoring the rehabilitation process to develop standardized exercise rehabilitation protocols.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.
