Hypercoagulable state (HCS) after kidney transplantation is one of the common and serious complications in kidney transplant recipients, which has attracted increasing attention in recent years. HCS refers to the abnormal and excessive activation of blood coagulation function, leading to the increased risk of thrombosis. After kidney transplantation, the combined effects of hemodynamic changes, surgical trauma and severe rejection increase the incidence of HCS, not only raising the risk of thrombosis but also potentially causing graft failure and affecting the postoperative survival rate of patients. This article reviews the influencing factors, clinical manifestations, diagnostic methods and preventive strategies of HCS after kidney transplantation, aiming to provide a theoretical basis for optimizing perioperative management and improving the prognosis of patients.

Objective To investigate the relation between obstructive sleep apnea(OSA)and tinnitus.Meth-ods The data of subjects aged 20 years or above who participated in tinnitus and sleep questionnaire survey from the 2005-2008 and 2015-2018 National Health and Nutrition Surveys(NHANES)had been used,the people at risk of OSA were selected via the STOP-Bang questionnaire,and the association between the people at risk of OSA and tinnitus was determined by a Logistic regression model.Results Among the 5 183 participants,83.3％(4 320/5 183)and 16.7％(863/5 183)were classified into the non-tinnitus and tinnitus group,respectively.The tinnitus group had higher STOP-Bang scores(3.71±1.51)than those of the group without tinnitus(2.81±1.62)(P＜0.001).The observed prevalence rates of tinnitus in the low-risk,middle-risk and high-risk group were 8.1％(175/1 973),20.5％(435/1 689),27.8％(253/658),respectively.The multivariate Logistic regression model showed that patients with middle-risk and high-risk of OSA had an increased risk of tinnitus compared with low-risk group,with the OR values and confidence intervals of 2.348(1.920～2.871)and 3.136(2.488～3.953),respec-tively(P＜0.001).Conclusion People at risk of OSA are independently risk factors of tinnitus.Higher risk of OSA is associated with higher prevalence and higher risk of tinnitus.

Objective:To investigate the efficacy and safety of fluoroscopically-guided percutaneous gastrostomy (FGPG) for establishing enteral nutrition access in the treatment of esophageal fistula after radiotherapy for cervical esophageal cancer (CEC).Methods:A retrospective analysis was conducted on the clinical data of 54 patients who underwent FGPG due to esophageal fistula after radiotherapy for CEC at our department from November 2009 to August 2019. All patients received endoscopy before radiotherapy, and CEC was pathologically confirmed. Enteral nutrition support was offered through a gastrostomy tube postoperatively. The success rate of FGPG, complications, and healing of perforation were recorded and analyzed.Results:FGPG was successfully performed in all 54 patients (100%). During the 12-month follow-up, 50 patients (92.6) survived while four (7.4%) died. Among 36 patients with esophagomediastinal fistula, 32 (88.9%) healed in a median of 12 weeks; of 18 patients with esophagotracheal fistula, 8 (44.4%) healed in a median of 18 weeks. Thus, patients with esophagomediastinal fistula had a significantly higher healing rate ( P<0.01) and shorter healing time ( P=0.017). Gastrostomy tube-related complications were minimal, and no serious complication was noted. Conclusions:FGPG is effective for the treatment of esophageal fistula after CEC radiotherapy and may be an alternative treatment for esophageal fistula.

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.

Background and Aims:CNLC stage IIIb hepatocellular carcinoma(HCC)is often accompanied by extrahepatic metastases and carries a poor prognosis.The optimal treatment strategy for these patients remains controversial,and the role of local therapy lacks robust evidence.This study aimed to compare overall survival(OS)between patients receiving combined local and systemic therapy versus systemic therapy alone,and to assess the prognostic impact of oligometastatic status and the cumulative duration of no evidence of disease(NED).Methods:A retrospective analysis was conducted on 76 CNLC stage IIIb HCC patients treated at Xiangya Hospital from January 2017 to December 2023.Forty patients received systemic therapy plus local therapy(local therapy group),and 36 received systemic therapy alone(no local therapy group).OS was compared between the two groups.Subgroup analyses were performed for oligometastatic and non-oligometastatic patients to evaluate the benefit of local therapy.In the local therapy group,the correlation between cumulative NED duration and OS was also examined.Results:The 1-,2-,3-,and 5-year OS rates were 89.0%vs.66.7%,64.3%vs.25.6%,35.3%vs.8.7%,and 8.3%vs.0.0%for the local therapy and no local therapy groups,respectively,with a statistically significant difference(P=0.003).Among oligometastatic patients,the local therapy group had significantly better OS than the no local therapy group(P=0.008),whereas no significant difference was observed in non-oligometastatic patients(P>0.05).Multivariate analysis identified oligometastases as an independent prognostic factor(HR=2.213,P=0.045).In the local therapy group,cumulative NED duration was strongly correlated with OS(r=0.851,P<0.001).Local therapy was well tolerated,with no treatment-related deaths observed.Conclusion:For CNLC stage IIIb HCC patients with well-controlled intrahepatic disease,local therapy can significantly prolong survival,particularly in those with oligometastases.Achieving and maintaining NED may represent an important therapeutic goal in this patient population.

Objective To study the effect and molecular mechanism of vitamin D(VitD)on Tfh cells of MRL/lpr lupus mice.Methods C57/B6 mice and MRL/lpr lupus mice were transfected with siRNA to construct VDR knockout mouse models.Splenic Tfh cells of C57/B6 mice and MRL/lpr lupus mice were divided into control group,lupus group and VDRsiRNA lupus group(treated with vitamin D 0,1 and 10 nmol·L-1,respectively)by siRNA transfection.The percentage of Tfh cells was detected by flow cytometry.MRL/lpr lupus mice Peyer node Tfh cells were randomly divided into 7 groups,blank control group,vitamin D dose groups of 1 and 10 nmol·L-1,paricalcitol group(VitD 10 nmol·L-1+PA),VDRsiRNA control group,VDRsiRNA group(VitD 10 nmol·L-1),CaN inhibitor group(VitD 10 nmol·L-1+CsA),and incubated for 72 h.The concentration of calcium ions in Tfh of each group was detected.The expressions of AT1R,NFAT,CaN and P-CaN in Tfh cells were determined by Western blotting.Results The percentage of Tfh cells decreased significantly with the increase of vitamin D dose.Vitamin D CaN reduce the intracellular calcium concentration of Tfh,up-regulate the expression of AT1 protein in Tfh cells,and down-regulate the expression of CAN,P-CaN and NFAT protein in a dose-dependent manner,and the effect is more obvious when combined with PA.Conclusion Vitamin D may regulate the activation of follicular T helper cells in MRL/lpr mice via the Ca-CaN-NFAT pathway.
