OBJECTIVE Based on comment texts from the Weibo platform， this study adopts the text mining method to systematically analyze the public’s emotional attitudes and core concerns of “medical insurance reimbursement”， and explore the public’s real experiences and feedback in the implementation of the current system. METHODS With “medical insurance reimbursement” as the keyword， Python web crawler technology was used to collect Weibo comment texts from December 2023 to April 2025. Word frequency analysis， sentiment analysis， semantic network analysis and Latent Dirichlet Allocation （LDA） topic models were adopted to mine the in-depth features of comment texts and investigate the public’s concerns and emotional attitudes toward “medical insurance reimbursement”. RESULTS A total of 3 645 valid comment texts were obtained. The overall emotional of the public toward “medical insurance reimbursement” was weakly positive： 66.4% of the comments contained positive emotions， and 32.4% contained negative emotions. Semantic network analysis indicated that positive public emotions mainly centered on the achievements of medical insurance reform and the improvement of security level， while negative emotions mainly focused on reimbursement rules， economic burden and the implementation of medical insurance policies. The LDA model identified eight core themes， mainly including access of new drugs to medical insurance catalogs， medical insurance support for traditional Chinese medicine and biomedicine， disputes over medical insurance coverage of specific medical items， cross-regional medical treatment and medical insurance settlement， medical insurance reimbursement and medical burden， as well as the approval of innovative drugs and medical insurance payment. CONCLUSIONS The public generally holds a positive attitude toward “medical insurance reimbursement”， yet still has many expectations in terms of policy implementation. On the premise of guaranteeing the sustainability of medical insurance funds， it is suggested to further improve the transparency and fairness of the reimbursement process， and promote the scientific， standardized and efficient development of the medical insurance system. Meanwhile， attention should be paid to public opinion feedback on social media， and the policy communication mechanism should be strengthened， so as to enhance the public’s sense of gain and trust in the medical insurance system.

Objective To establish a rat model of Alzheimer's disease (AD) expressing human triple mutant amyloid precursor protein (APP) in the hippocampus, and to provide a model for the study of disease mechanisms and drug development. Methods Twenty-four 12-week-old SPF-grade female SD rats were randomly divided into a blank control group, a virus control group and an experimental group, with eight rats in each group; among them, the experimental group received a stereotaxic injection of adeno-associated virus (AAV) carrying the human triple mutant APP and NanoLuc luciferase genes into the hippocampus. In vivo imaging was used to observe viral expression in the brains of rats in each group, the novel object recognition test was used to assess the recognition memory of the rats in each group, real-time fluorescent quantitative PCR was used to detect the expression level of the APP gene, HE staining was used to examine the brain histopathology, Nissl staining was used to assess the hippocampal lesions, and immunohistochemistry was used to detect the deposition of amyloid β-protein (Aβ). Results In vivo imaging showed that reporter fluorescence was detected in the brains of rats in both experimental and virus control groups. Fluorescence quantitative PCR showed that the expression level of the APP gene was significantly increased in the brains of rats in the experimental group (P<0.01). Novel object recognition test revealed that the recognition memory of rats in the experimental group was significantly reduced compared with that of the blank control group (P<0.01). Six months after recombinant AAV virus infection, HE staining and Nissl staining of brain tissues showed that the number of neurons and Nissl bodies in the CA1 region of the hippocampus in the experimental group was reduced and disorganized; immuno-histochemistry testing of the CA1 region of the hippocampus and the pyramidal cell layer of the experimental group revealed prominent brown deposits, indicating Aβ protein deposition. Conclusion The rat model successfully established by stereotaxic injection and AAV-mediated delivery of human triple mutant APP gene exhibits typical AD features, providing a valuable animal model for studying AD pathology and developing drug therapies targeting Aβ protein deposition.

Objective To investigate the adverse pregnancy outcomes of fetuses with increased nuchal translucency(NT).Methods A total of 376 pregnant women at the Third Affiliated Hospital of Zhengzhou University from May 2023 to January 2024 were selected as research subjects,who had a diagnosis of fetal NT ≥ the 95th percentile and complete pregnancy outcomes for singleton pregnancies.The fetuses were divided into simple thickening group(n=320)and thickening with structural abnormalities group(n=56)based on NT ultrasound results.The interventional prenatal diagnosis outcomes and pregnancy outcomes of two groups were compared.Results The rate of chromosomal abnormalities and the incidence of adverse pregnancy outcomes were higher in thickening with structural abnormalities group compared to simple thickening group with statistically significant differences(P＜0.05).The overall incidence of adverse pregnancy outcomes in NT thickened fetuses was 31.65％,but after excluding chromosomal abnormalities and structural malformations,the good pregnancy outcome rate in NT thickened fetuses was 98.09％.Conclusion NT thickening is associated with adverse pregnancy outcomes in fetuses,and the risk of poor fetal outcome is further increased when NT thickening combined with structural abnormalities in early pregnancy,but the pregnancy outcome is better in fetuses with NT thickening after excluding chromosomal abnormalities and structural malformations.

Objective To observe the correlation between fat fraction(FF)and T2 value of multifidus muscle and Pfirrmann grade of L4-5 intervertebral disc in patients with lumbar muscle strain.Methods Totally 200 L4_5 intervertebral discs in 200 patients with lumbar muscle strain were retrospectively enrolled,including 6 cases of Pfirrmann grade Ⅰ,61 of grade Ⅱ,52 of grade Ⅲ,56 of grade Ⅳ and 25 cases of grade V.Based on modified DIXON quantification(mDIXON-Quant)and T2 mapping,FF and T2 value of multifidus muscle were calculated and compared among intervertebral discs with different Pfirrmann grades,and the correlations between the above parameters and Pfirrmann grade of intervertebral disc were analyzed.Results Significant differences of left,right and bilateral multifidus muscles FF,as well as of T2 values in left and bilateral multifidus muscles were found among L4-5 intervertebral discs with different Pfirrmann grades.Multifidus muscle FF was moderately positively correlated with Pfirrmann grade of L4-5 intervertebral disc(r=0.538,P＜0.05),while T2 value was weakly positively correlated with Pfirrmann grade of L4-5 intervertebral disc(r=0.202,P＜0.05).Conclusion FF of multifidus muscle was moderately positively correlated with Pfirrmann grade of L4-5 intervertebral disc,while T2 value of multifidus muscle was weakly positively correlated with Pfirrmann grade of L4-5 intervertebral disc in patients with lumbar muscle strain.

Background and Aims:To overcome the limitations of the transoral endoscopic thyroidectomy vestibular approach,such as restricted operative space and high complication risks,our team proposed a modified technique—endoscopic thyroidectomy via oral vestibule and submandibular approach(ETOSA).Preliminary studies have confirmed its safety and feasibility.This study aims to systematically evaluate the key factors affecting postoperative complications and operative time in ETOSA,explore the interactions among these variables,and construct a learning curve model to support its broader clinical adoption.Methods:A retrospective analysis was conducted on 125 patients with papillary thyroid carcinoma who underwent ETOSA at Xiangya Hospital,Central South University,between March 2022 and March 2023.Clinical characteristics,surgical parameters,and postoperative complications were extracted.A random forest model was employed to identify the major influencing factors for complications and operative time,as well as their interaction effects.Partial dependence plots based on case sequence were used to generate the learning curve.Results:All 125 patients successfully underwent ETOSA with no conversion to open surgery.The median operative time was 95.0 min,and the median intraoperative blood loss was 15.0 mL.The overall postoperative complication rate was 16.0%,with no cases of permanent hypoparathyroidism or hypocalcemia.The average neck appearance score was 1.05,indicating high patient satisfaction.The random forest analysis identified case number,surgical extent,lymph node yield(LNY),Hashimoto's thyroiditis(HT),and body mass index(BMI)as the key predictors of postoperative complications,while surgical extent,case number,LNY,HT,and blood loss were the key factors affecting operative time.A significant positive interaction was observed between case number and both surgical extent and HT,particularly in the first 20 cases,suggesting a higher risk during the early learning phase.The learning curve analysis indicated that surgical proficiency stabilized after 20 cases.Operative time and complication rate in the proficient phase were significantly lower than those in the learning phase(90.0 min vs.102.5 min;11.4%vs.40.0%,both P<0.05).Conclusion:ETOSA is a safe and feasible technique characterized by minimal invasiveness,favorable cosmetic outcomes,and a relatively short learning curve.case number,surgical extent,LNY,HT,BMI,and blood loss are key factors affecting complications and operation time.

OBJECTIVE: To observe the clinical efficacy of meridian sinew manipulation releasing technique combined with heat-sensitive moxibustion for simple obesity. METHODS: Twenty-nine patients with simple obesity were selected, on the basis of the conventional treatment, the patients were treated with meridian sinew manipulation releasing technique on the affected meridian sinews in the abdomen and lower limbs, about 30 min a time. After releasing, using the moxibustion sensation localization method in the abdominal regions with high heat-sensitivity frequency (including acupoints such as Zhongwan [CV12], Tianshu [ST25], Qihai [CV6], Guanyuan [CV4]), 2 heat-sensitive acupoints were selected for moxibustion and moxibustion was applied at each acupoint for 40 min, or until the heat-sensitive moxibustion sensation disappeared. The patients were treated once every other day for a total of 20 times. The weight, body mass index (BMI), body fat rate, waist circumference and hip circumference of the patients before and after treatment were observed, and the clinical efficacy was evaluated after treatment. RESULTS: After treatment, the weight, BMI, body fat rate, waist circumference and hip circumference of the patients were decreased compared with those before treatment (P<0.05). The total effective rate was 93.1% (27/29). CONCLUSION Meridian sinew manipulation releasing technique combined with heat-sensitive moxibustion can effectively treat simple obesity, the treatment from the perspective of meridian sinews provides a new idea and plan for simple obesity.

The liver regenerative capacity is crucial for patients with end-stage liver disease following partial hepatectomy (PHx). The specific bacteria and mechanisms regulating liver regeneration post-PHx remain unclear. This study demonstrated dynamic changes in the abundance of Parabacteroides distasonis (P. distasonis) post-PHx, correlating with hepatocyte proliferation. Treatment with live P. distasonis significantly promoted hepatocyte proliferation and liver regeneration after PHx. Targeted metabolomics revealed a significant positive correlation between P. distasonis and β-hydroxybutyric acid (BHB), as well as hyodeoxycholic acid and 3-hydroxyphenylacetic acid in the gut after PHx. Notably, treatment with BHB, but not hyodeoxycholic acid or 3-hydroxyphenylacetic acid, significantly promoted hepatocyte proliferation and liver regeneration in mice after PHx. Moreover, STAT3 inhibitor Stattic attenuated the promotive effects of BHB on cell proliferation and liver regeneration both in vitro and in vivo. Mechanistically, P. distasonis upregulated the expression of fatty acid oxidation-related proteins, and increased BHB levels in the liver, and then BHB activated the STAT3 signaling pathway to promote liver regeneration. This study, for the first time, identifies the involvement of P. distasonis and its associated metabolite BHB in promoting liver regeneration after PHx, providing new insights for considering P. distasonis and BHB as potential strategies for promoting hepatic regeneration.
