Objective To investigate the clinical and imaging features of right-side non-thrombotic iliac vein compression syndrome(NIVCS),and to evaluate the efficacy of endovascular treatment.Methods The clinical data and imaging materials of lower extremity venography from January 2019 to February 2024 in Affiliated Nanjing Gaochun People's Hospital,Jiangsu University were retrospectively analyzed.The patients with clinically diagnosed right-side NIVCS who received endovascular treatment were selected for this study.The clinical features and imaging findings,technical success rate,postoperative clinical improvement,and stent patency rate were analyzed.Results The median follow-up time was 30.2 months(3-58 months).A total of 24 patients with right-side NIVCS(aged 42-73 years)were enrolled in this study.Of the 24 patients,22(91.7％)were male and only 2(8.3％)were female,the proportion of male was significantly higher than that of female(P＜0.001).According to Clinical Etiologic Anatomic Pathophysiologic(CEAP)grading,14 patients were of grade C3,9 patients were of grade C,and one patient was of grade C.Imaging examination showed that the most frequent site of compression was the proximal end of the external iliac vein(15/24,62.5％),the second frequent site of compression was the proximal part of the common iliac vein bifurcation(5/24,20.8％).The most common external pressure structure was the internal and external iliac arteries(14/24,58.3％),the second common external pressure structure was external iliac artery and sacrum(5/24,20.8％).The technical success rate was 100％,and only one stent was implanted in each patient(diameter of 12-14 mm and length of 80-90 mm).The most commonly used stent was the Smart control(19/24,79.2％).During follow-up period,the remission rate of edema was 85.7％(18/21),the ulcer healing rate was 100％(1/1),and all stents remained patent.Conclusion Right-side NIVCS is more commonly seen in male patients.Because the compression site is usually located at the distal end of iliac vein,thus,the implanted stent may rarely affect blood flow in the contralateral iliac vein.Therefore,endovascular treatment is a safe and effective method for right-side NIVCS.

Objective To analyze the influencing factors of poor incision healing in postoperative patients with breast cancer.Methods The clinical data of 150 patients with breast cancer diagnosed by the Department of Nail Milk surgery of the Fifth affiliated Hospital of Xinjiang Medical University from January 2016 to December 2023 were retrospectively analyzed.According to the postoperative wound healing,the patients were divided into two groups:good healing group(n=94)and poor healing group(n=56).The general data,operation-related data and clinicopathological characteristics of the two groups were collected for univariate analysis,and the single-factor indexes with statistical significance were analyzed by multivariate Logistic analysis to screen the risk factors of poor incision healing after operation.The statistically significant indexes of regression analysis were analyzed by receiver operating characteristic(ROC)curve to further explore its predictive value in poor incision healing after breast cancer operation.Results The data of the two groups were compared and analyzed.Multivariate Logistic regression analysis showed that BMI,diabetes,age,axillary lymph node dissection and hemoglobin were independent risk factors for poor incision healing(P＜0.05).ROC curve analysis of independent risk factors showed that when the age was more than 57.5,the area under the curve(AUC)was 0.635,the sensitivity was 55.4％,the specificity was 68.1％,and the critical value was 57.5.When BMI＞24.9 kg/m2,the area under the curve(AUC)was 0.735,the sensitivity was 87.5％,the specificity was 61.7％,and the critical value was 24.9(P＜0.001).When hemoglobin＜101.5 g/L,the area under the curve(AUC)was 0.829,the sensitivity was 57.1％,the specificity was 94.7％,and the critical value was 101.5 g/L(P＜0.001).Conclusion BMI,diabetes,hemoglobin,age and axillary lymph node dissection are independent risk factors for poor wound healing after breast cancer operation.When BMI＞24.9 kg/m2,age＞57.5 years old and hemoglobin＜101.5 g/L,it can predict the occurrence of poor incision healing in patients with breast cancer.

This report described a periviable extremely preterm infant who received Nirsevimab before discharge for preventing respiratory syncytial virus infection. The infant was born at 22?3 weeks' gestation with a birth weight of 360 g. Nirsevimab was administered on January 12, 2025 (110 days after birth, corrected gestational age of 38?2 weeks) at the Women and Children's Medical Center of Southern Medical University (Shenzhen Maternity & Child Healthcare Hospital). No local or systemic adverse reactions were observed following administration. Follow-up until 1 year and 2 months of age (November 2025) revealed no occurrence of respiratory syncytial virus infection.

Objective To explore the application value of glucocorticoid in the treatment of elderly patients with severe pneumonia(SP)and respiratory failure(RF).Methods A retrospective analysis was performed on the clinical data of 208 elderly patients with SP and RF in the hospital between January 2022 and December 2023.According to use of glucocorticoid or not,patients were divided into non-hormone group(n=83)and hormone group(n=125).According to propensity score matching method,there were 71 patients in each group.The clinical indexes,disease improvement,blood gas indexes,laboratory biochemical indexes and prognosis were compared between the two groups.Results The ventilator use time and length of hospital stay in hormone group were shorter than those in non-hormone group(P<0.05).After 7 d of treatment,score of Glasgow coma scale(GCS),oxygen-ation index(P/F),blood oxygen saturation(SaO2)and lymphocyte count(TLC)in hormone group were higher than those in non-hormone group,while scores of acute physiological and chronic health evaluation Ⅱ(APACHE Ⅱ)and sequential organ failure assessment(SOFA),partial pressure of carbon dioxide(PaCO2),blood lactic acid (LAC)and procalcitonin(PCT)were lower than those in non-hormone group(P<0.05).The survival curves showed that 28 d survival rate in hormone group was higher than that in non-hormone group(P<0.05).Cox pro-portional hazard model showed that no use of glucocorticoids was an independent risk factor of 28d death in elderly patients with SP and RF(P<0.05).Conclusion Glucocorticoid can shorten ventilator use time and length of hospital stay,alleviate disease severity,promote the recovery of blood gas indexes,improve biochemical indexes and increase survival rate in elderly patients with SP and RF.

Ulcerative colitis （UC） is a chronic intestinal disease with unknown etiology， with main symptoms of abdominal pain， diarrhea， mucus， pus， and blood in the stool. It can be accompanied by various complications and has a high risk of developing to colon cancer. In recent years， the incidence of UC and related colon cancer has been increasing， which seriously affects human health and quality of life. The operation， immunosuppressant， etc. are the main approaches in the modern clinical treatment of UC and related colon cancer， but these methods all have different toxic and side effects， and the therapeutic effect is not ideal. For many years， traditional Chinese medicine （TCM） has attracted much attention in the treatment of UC and related colon cancer due to its slightly toxic side effects and remarkable curative efficacy. Huangqintang， derived from the Shang Han Lun （伤寒论）， is composed of Scutellariae Radix， Paeoniae Radix Alba， Glycyrrhizae Radix et Rhizoma， and Jujubae Fructus with the functions of clearing heat， checking diarrhea， harmonizing the middle， and relieving pain， and has a significant effect on the treatment of UC. Huangqintang has complex compositions and plays roles with multiple targets and pathways. According to the literature and the research results of this research group for many years， it was found that the mechanism of Huangqintang in the treatment of UC and related colon cancer was presumably related to the protection of the intestinal mucosal barrier， inhibition of inflammatory response， promotion of mitophagy， inhibition of oxidative stress， regulation of intestinal flora， cell cycle， and gene expression， suppression of cell proliferation， and promotion of apoptosis. To provide theoretical references for an in-depth study of the mechanism and clinical use of Huangqintang， this paper reviewed the research advances in recent years.
