Autoimmune hepatitis （AIH） is an immune-mediated chronic liver inflammatory disease with unknown pathogenesis， and intestinal barrier dysfunction is considered an important factor. Meanwhile， there are sex and age differences in the incidence rate of AIH， suggesting that hormone may be involved in regulation. On this basis， this article focuses on the association between estrogen， intestinal barrier， and immune homeostasis， systematically reviews the evidence that estrogen deficiency disrupts intestinal barrier homeostasis， and further summarizes the potential mechanism of estrogen in regulating the development and progression of AIH via intestinal barrier.

OBJECTIVE To evaluate the clinical comprehensive value of four Chinese patent medicines （Xuezhikang， Zhibitai， Zhibituo， Jiangzhiling） in the treatment of hyperlipidemia， and provide a reference for rational clinical drug use. METHODS A clinical comprehensive evaluation index system was established in accordance with the Evidence and Value： Impact on Decision-Making （EVIDEM） framework and Technical Guideline for Clinical Comprehensive Evaluation of Cardiovascular Drugs （2022 edition， trial implementation）. CNKI， Wanfang data， VIP， PubMed， ScienceDirect， Embase and official websites were retrieved to collect the literature such as drug instructions， guidelines and consensus statements， and systematic reviews/meta-analyses for the four Chinese patent medicines. A comprehensive evaluation was conducted from seven dimensions： effectiveness， safety， economy， suitability， accessibility， innovation and characteristics of traditional Chinese medicine. RESULTS This evaluation index system included 7 first-level indicators， 15 second-level indicators and 30 third-level indicators. Xuezhikang achieved the highest comprehensive evaluation score of 81.4 points， and was classified as class Ⅰ recommendation. Zhibitai with 76.0 points and Zhibituo with 60.9 points were both classified as class Ⅱ recommendation. Jiangzhiling with 48.8 points was classified as class Ⅳ recommendation. CONCLUSIONS Xuezhikang demonstrates the optimal clinical comprehensive value for treating hyperlipidemia. Zhibitai exhibits certain advantages in terms of safety and characteristics of traditional Chinese medicine； Zhibituo shows a moderate performance in all aspects； Jiangzhiling has a relatively low score. Appropriate medicines can be selected clinically according to actual conditions and patients’ characteristics.

ObjectiveTo investigate the protective effects and mechanisms of Bushen Zhuyun prescription （BSZY） on abortion rats with kidney deficiency-corpus luteum inhibition syndrome. MethodsAn abortion rat model with kidney deficiency-corpus luteum inhibition syndrome was constructed. Pregnant mice aged 8-10 weeks were randomly divided into a control group （Control）， a model group （Model）， low-dose BSZY （BSZY-L）， medium-dose BSZY （BSZY-M）， and high-dose BSZY （BSZY-H） groups （2.57， 5.14， 10.28 g·kg^-¹）， and a Zishen Yutai Pill （ZSYT） group （1.575 g·kg^-¹）. Hematoxylin-eosin （HE） staining was used to evaluate histopathological changes in ovarian and decidual tissue of rats in each group. Enzyme-linked immunosorbent assay （ELISA） was employed to measure levels of estrogen （E₂）， progesterone （P）， luteinizing hormone （LH）， prolactin （PRL）， and follicle-stimulating hormone （FSH） in serum. The candidate targets of BSZY were obtained from the Traditional Chinese Medicine System Pharmacology Platform （TCMSP） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP） v2.0 databases， while disease targets for recurrent spontaneous abortion （RSA） were retrieved from GeneCards， DrugBank， Online Mendelian Inheritance in Man （OMIM）， and Therapeutic Target Database （TTD）. The intersection targets were identified by the Venny 2.1.0 platform. Pathway enrichment analysis was conducted based on the Metascape database to predict the potential mechanisms of BSZY. Additionally. Western blot was used to verify the effects of BSZY on the expression of estrogen receptor （ERα）， phosphatidylinositol 3-kinase （PI3K）， and protein kinase B （Akt） and explore its protective mechanism on RSA rats. ResultsCompared with the control group， the model group exhibited significantly decreased uterine， ovarian， and embryonic wet weights （P<0.05， P<0.01）， with an abortion rate of 57.18%. The ovarian tissue showed varying degrees of reduction in primordial follicles， primary follicles， mature follicles， and corpora lutea， along with a large number of atretic follicles. The endometrium was thinner， and decidual tissue exhibited cellular edema and disorganized arrangement. In contrast， compared with the model group， the BSZY groups at all doses and the ZSYT group demonstrated increased uterine， ovarian， and embryonic wet weights， along with a reduced abortion rate. The number of primordial follicles， primary follicles， mature follicles， and corpora lutea increased， while atretic follicles decreased. The endometrium thickened， and decidual tissue displayed normal cellular structure with tight arrangement. Additionally， the model group showed significantly decreased levels of E₂， P， PRL， and FSH in serum （P<0.05， P<0.01）， along with a decreasing trend in LH level. In contrast， the BSZY groups at all doses exhibited significantly elevated levels of E₂， P， LH， PRL， and FSH in serum （P<0.05， P<0.01）. Network pharmacology predictions suggested that BSZY may exert protective effects against abortion in rats by activating the ERα/PI3K/Akt signaling pathway. Western blot results confirmed that BSZY significantly upregulated the expression of ERα， PI3K， and p-Akt proteins （P<0.05， P<0.01）. ConclusionBSZY has a protective effect on the abortion rats with kidney deficiency-corpus luteum inhibition syndrome， possibly by activating the ERα/PI3K/Akt signaling pathway to reduce ovarian apoptosis and regulate endocrine function， thereby lowering the abortion rate.

Objective To investigate the correlation between skeletal muscle fat content and diabetic peripheral neuropathy(DPN)in patients with type 2 diabetes mellitus(T2DM).Methods 290 patients with T2DM admitted to our hospital were enrolled in this study from January 2023 to February 2024 and divided into two groups according to whether they were complicated with DPN:simple T2DM group(T2DM,n=98)and T2DM with DPN group(DPN,n=192).The general data,biochemical indexes and fat distribution indexes measured based on quantitative CT were compared between the two groups.Spearman correlation was used to analyze the relationship between fat distribution indexes and DPN,logistic regression analysis of influencing factors of T2DM complicated with DPN.Results Age,DM duration,WHR,FIns,insulin resistance index(HOMA-IR)and FF were higher in DPN group than in T2DM group(P<0.05).Ca,subcutaneous abdominal fat area(SFA)and liver fat content were lower in DPN group than in T2DM group(P<0.05).Spearman correlation analysis showed that DPN was negatively correlated with SFA and liver fat content(r=-0.127,-0.123,P<0.05),and positively correlated with FF(r=0.117,P<0.05).Logistic regression analysis showed that without adjusting for confounding factors and adjusting for DM duration,WHR,HOMA-IR,Ca,SFA and liver fat content,FF was an influential factor for DPN in T2DM patients.Conclusions Skeletal muscle FF was associated with DPN in patients with T2DM.

Objective To investigate the karyotypes and the correlation of chromosomal abnormalities in the fetuses with increased nu-chal translucency(NT),so as to provide a basis for prenatal genetic counseling.Methods The clinical data of 386 singleton pregnant women with NT≥2.5mm who underwent invasive prenatal diagnosis at the First Affiliated Hospital of Nanjing Medical University from January 2018 to April 2022 were retrospectively analyzed.The fetuses were grouped according to NT thickness(2.5-3.4,3.5-3.9,4.0-4.9,5.0-5.9,and ≥6.0 mm),fetal ultrasound abnormalities(isolated increased NT,non-isolated increased NT),and maternal age(advanced age ≥35 years,non-advanced age＜35 years).The chi-square test was used to compare the differences of the incidence of fetal chromosomal abnormalities among various groups.Results Among the 386 fetuses with increased NT,chromosomal abnormalities were detected in 87 cases with an overall detection rate of 22.5％(87/386),including chromosomal numerical abnormalities accounted for 82.8％(72/87)and copy number variations(CNVs)accounted for 17.2％(15/87).The detection rates of chromosomal abnormal-ities and numerical abnormalities increased with NT thickness(P＜0.05),while no statistically significant difference of CNV abnormali-ty rates was found(P=0.41).The detection rates of chromosomal abnormalities(36.5％)and CNV abnormalities(14.1％)in the non-isolated increased NT group were significantly higher than those in the isolated increased NT group(18.6％and 1.0％,respective-ly,both P＜0.05).The detection rates of chromosomal abnormalities(34.7％)and numerical abnormalities(31.6％)in the fetuses of advanced maternal age mothers with increased NT were significantly higher than those in the non-advanced age group(18.4％and 14.2％,respectively,both P＜0.05).However,the difference of CNV abnormality rates between the two groups was not statistically sig-nificant(P=0.62).Conclusion The detection rate of fetal chromosomal abnormalities elevated with increased NT thickness.Ad-vanced maternal age and the presence of other ultrasound abnormalities were the high-risk factors for fetal chromosomal abnormalities.The risks of CNV abnormalities may not be significantly correlated with NT thickness or maternal age but associated with the presence of other ultrasound abnormalities.

Objective:To evaluate the effect of trans-nasal humidified rapid insufflation ventilatory exchange (THRIVE) on the early postoperative atelectasis in patients undergoing prolonged non-intubated intravenous anesthesia for gastrointestinal endoscopic procedures.Methods:In this randomized double-blind controlled trial, 150 patients of either sex, aged 18-80 yr, with American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ and body mass index of 18-30 kg/m 2, scheduled for endoscopic mucosal resection of multiple colorectal polyps at Northern Jiangsu People′s Hospital Affiliated to Yangzhou University from February 18 to June 15, 2024, were divided into 2 groups ( n=75 each) using simple random allocation: THRIVE group (group T) and conventional oxygen therapy group (group C). In group T, the oxygen flow rate was 10 L/min before anesthesia induction and increased to 50 L/min after induction until the end of operation, and the inhaled oxygen concentration was 100%. Group C used conventional mask oxygen inhalation, with an oxygen flow rate of 10 L/min during anesthesia induction and maintenance. Lung ultrasonography was performed immediately before anesthesia induction and after the end of surgery, and the modified lung ultrasound score and diaphragm mobility during quiet breathing were recorded to assess the occurrence of atelectasis and diaphragmatic dysfunction. The lowest intraoperative SpO 2 value, adverse events during surgery and in the postanesthesia care unit (PACU), duration of PACU stay, adverse events within 7 days after operation, hospitalization duration, and satisfaction scores of both patients and endoscopists were recorded. Results:Compared with group C, the postoperative modified lung ultrasound score and incidence of atelectasis and diaphragmatic dysfunction were significantly decreased, the lowest intraoperative SpO 2 value was increased, the incidence of hypoxemia was decreased, the duration of PACU stay was shortened, and endoscopists′ satisfaction scores were increased ( P<0.05), and no statistically significant changes were observed in diaphragm mobility, incidence of other intraoperative adverse events, incidence of adverse events during PACU stay and within 7 days after operation, or patients′ satisfaction scores in group T ( P>0.05). Conclusions:THRIVE can reduce the risk of early postoperative atelectasis and intraoperative hypoxemia, thereby promoting postoperative recovery of patients undergoing gastrointestinal endoscopy under long-term non-intubated anesthesia.

Objective To explore the imaging manifestations of Rosai-Dorfman disease(RDD)in children.Methods A total of 12 children with RDD confirmed by pathology were retrospectively enrolled,including 8 cases underwent non-contrast CT(NCCT)+contrast enhanced CT(CECT),2 cases underwent NCCT+CECT+non-contrast MR(NCMR)+contrast enhanced MR(CEMR),1 case underwent NCCT+NCMR and CEMR,while 1 case underwent NCCT and X-ray examinations.Imaging manifestations of RDD in children were observed.Results Among 12 cases,intranodal type RDD was found in 7 case,extranodal type RDD in 3 cases,and mixed type(with both lymph nodes and extranodal sites affected)RDD were noticed in 2 cases.In 7 cases of intranodal type RDD,NCCT and CECT showed multiple lymph node enlargements in both sides of the neck,with uniform isodensity on NCCT and mild-moderate progressive enhancement in 5 cases,while with low-density necrotic area and ring-shaped enhancement in 2 cases.Among 3 cases of extranodal RDD,the lesion in 1 case involved nasal cavity and posterior group of ethmoid sinuses on CT and MRI,which developed circular soft tissue mass centered on nasal septum with moderate heterogeneous enhancement,also compressed the adjacent bone with destruction.In another case of extranodal RDD,CT showed that the lesion involved left ilium and bilateral parietal bones,with bone destruction accompanied by obvious periosteal reaction and soft tissue mass,which was mildly enhanced.In the rest 1 case of extranodal RDD,CT and X-ray film showed that the lesion involved the upper segment of right femur and left parietal bone,with osteolytic destruction accompanied by layered periosteal reaction.The lesions in both 2 cases of mixed type RDD involved brain(1 case involved left parieto-occipital lobe,1 case involved bilateral temporal lobes,left frontal lobe and bilateral occipital lobes),presented as isodensity on CT and equal or slightly low signal intensity on T 1WI,equal-high mixed signal intensity on T2WI,some shaped like brain gyral with mild edema of surrounding tissue,and nodular or mass-like significant enhancement.RDD involvements of bilateral lung,mediastinum and hilar lymph nodes were also observed in the above 2 cases,chest CT showed multiple nodular or small patchy uniform high-density shadows in bilateral lungs,as well as enlarged mediastinum and hilar lymph nodes.Conclusion Imaging manifestations of pediatric RDD had certain specificity,being helpful to diagnosis.

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.
