ObjectiveTo explore the mechanism of Buzhong Yiqitang on pyroptosis in autoimmune thyroiditis （AIT） mice based on the NOD-like receptor hot protein domain related protein 3 （NLRP3）/cysteinyl aspartate specific proteinase-1（Caspase-1）/Gasdermin D （GSDMD） pathway. MethodSixty NOD.H-2^h4 mice were divided into normal group， model group， low， medium， and high dose groups （4.10， 8.19， 16.38 g·kg^-1）of Buzhong Yiqitang， and selenium yeast tablet group （0.26 mg·kg^-1）， with 10 mice in each group. Except for the normal group， all other groups were given 0.05% NaI by gavage for eight weeks to establish a model and then received the drug treatment for eight weeks. The serum levels of thyroid peroxidase antibody （TPO-Ab） and thyroglobulin antibody （TgAb） were detected using enzyme-linked immunosorbent assay （ELISA） method. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in mouse thyroid tissue. The immunohistochemical method was used to detect the protein expression of NLRP3， Caspase-1， interleukin-1β （IL-1β）， and interleukin-18 （IL-18）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of NLRP3， Caspase-1， IL-1β， and IL-18. Western blot was used to detect the levels of pyroptosis-related proteins in thyroid tissue. ResultCompared with the normal group， the serum levels of TPO-Ab and TgAb in the model group were significantly increased （P<0.01）. Thyroid follicles either increased in a cubic shape or were damaged and atrophied， with a large number of lymphocytes infiltrating around the follicles. Compared with the model group， the levels of TPO-Ab and TgAb in other groups were significantly reduced （P<0.01）， and the morphology and structure of follicles were improved. The degree of lymphocyte infiltration was reduced. Among them， the medium dose group of Buzhong Yiqitang had the most significant reduction and improvement effect. Compared with the normal group， the positive products and mRNA expression of NLRP3， Caspase-1， IL-1β， and IL-18 proteins in the thyroid tissue of the model group significantly increased （P<0.01）， and the protein expression levels of NLRP3， cleaved Caspase-1， IL-1β， IL-18， and GSDMD-N were significantly increased （P<0.05， P<0.01）. Compared with the model group， the positive products and mRNA expression of NLRP3， Caspase-1， IL-1β， and IL-18 proteins in other groups were significantly reduced （P<0.05， P<0.01）， with the most significant reduction effect in the medium dose group of Buzhong Yiqitang. The protein expression levels of NLRP3， cleaved Caspase-1， IL-1β， IL-18， and GSDMD-N were significantly reduced （P<0.05， P<0.01）. ConclusionBuzhong Yiqitang can improve AIT， and its mechanism may be achieved by regulating the NLRP3/Caspase-1/GSDMD signaling pathway to inhibit pyroptosis.

We studied the patients diagnosed with X-linked hypophosphatemicrickets(XLH) and treated with burosumab in Peking Union Medical College Hospital from January 2021 to December 2022. In addition, we described the clinical characteristics of the patients, the changes of clinical indexes before and after burosumab treatment, and the adverse drug reactions during treatment. We also evaluated the efficacy and safety of burosumab for XLH. The results showed that three children XLH patients and one adult XLH patients received burosumab treatment. After treatment, the serum phosphorus level of all patients increased; the serum phosphorus of 3 children patients increased above the lower limit of the reference value range; the serum alkaline phosphatase(ALP) of all patients was lower than that of before treatment; the serum ALP of one adult patient was close to the normal range after 2.5 years of treatment. One child patient showed small crystals in kidney through ultrasound 48 weeks after treatment; one child and one adult showed increased serum parathyroid hormone(PTH)level before treatment and serum PTH continued increasing after treatment. Finally, it may be concluded that burosumab increased serum phosphorus levels in XLH patients, kept the level relatively stable, and reduced serum ALP levels. No serious adverse reactions occurred during treatment, in order to provide reference for the use of burosumab in patients with XLH.

Objective This study aims to sort out the rare disease drugs in the China's Second List of Rare Diseases,to provide reference for the management of rare disease drug treatment.Methods Up to December 31,2023,based on the China's Second List of Rare Diseases,we sorted out the drugs approved in China with the drug label,or approved by the U.S.Food and Drug Administration(FDA)and the European Medicines Agency(EMA)for the treatment of the above diseases,and developed the second batch of rare dis-ease drug catalog in China.The accessibility,localization and coverage of the national medical insurance were also analyzed.Results From the point of view of diseases,a total of 37 diseases in the China's Second List of Rare Diseases have drug indications approved in China,and 10 diseases have drugs listed by the U.S.FDA/EMA and approved in China,but for off-label use.From the point of view of drugs,there are 55 drug indications ap-proved for the treatment of the China's Second List of Rare Diseases,and 22 drugs listed in the U.S.FDA/EMA and approved in the China,but for off-label use.Among the above-mentioned drugs with domestic approved rare disease indications or approved numbers,39 drugs have at least one domestic approval number for a dosage form,covering 30 rare diseases;37 drugs used for at least one rare disease are included in the national medical insur-ance catalog and are covered by reimbursement,covering 29 rare diseases.Conclusions The list of rare disease drugs in the China's Second List of Rare Diseases was established.The number of rare disease drugs and covered diseases approved by China and the U.S.FDA/EMA has increased,and the number of rare disease drugs and covered diseases that are localized and included in the medical insurance catalog has also continued to increase.

Objective To summarize and analyze what the listing in market of orphan drugs in China,the United States,the European Union,and Japan in 2023,and to provide empirical reference to Chinese phar-maceutical enterprises,pharmaceutical management,and new drug research and development departments.Methods Collect the 2023 drug market data released by official drug regulatory agencies in four countries and international organization-China,the United States,the European Union,and Japan categorize the market of rare disease drugs and and their indications,approval dates,R&D status in China,component therapeutic are-as,and special review and approval pathways were analyzed.Results Findings in 2023,28 orphan drugs were listed in the United States,mostly anti-tumor related,accounting for 32.1％(9 out of 28);17 orphan drugs were listed in the European Union,anti-tumor related accounting for 47.0％(8 of 17);22 listed in Japan;and 45 listed in China.In 2023,over 70％orphan drugs listed in the European Union and Japan entered the phase of clinical trials/marketing and applications/approved clinical applications in China(86.4％from Japan and 70.6％from European Union).Conclusions Currently,there is no qualification accreditation mechanism for orphan drugs in China.However,in 2023,the number of rare disease drugs listed in China was the greatest among the four countries/international organization.It reflects that China's Catalog for Rare Diseases played a guiding role in drug research and development.Meanwhile,the reform of drug approval and review in China and the issue of rare disease catalogs took place in a short period of time,so the review and approval,as well as re-search and development of rare disease drugs are still in the catching up stage.

Objective:To explore the latent profile types of capability-opportunity-motivation-behavior in stroke patients and analyze the influencing factors of different latent profiles.Methods:From January to October 2023, totally 596 stroke patients from the Neurology Department of five ClassⅢ Grade A hospitals in Henan Province were selected by stratified random sampling. The patients were surveyed using a general information questionnaire, the Stroke Prevention Knowledge Questionnaire (SPKQ), the Social Support Rating Scale (SSRS), the WHO's Quality of Life Questionnaire- Brief Version (WHOQOL-BREF), the Short Form Health Belief Model Scale (SF-HBMS), and the Health Promoting Lifestyle ProfileⅡ (HPLPⅡ). Latent profile analysis was used to classify the capability-opportunity-motivation-behavior characteristics of stroke patients, and multiple logistic regression was conducted to explore the influencing factors of different latent profiles.Results:Three latent profiles of capability-opportunity-motivation-behavior in stroke patients were identified, including low capability-opportunity-motivation-behavior with high health beliefs (32.4%, 193/596), moderate capability-opportunity-motivation-behavior with insufficient health beliefs (47.5%, 283/596), and high capability-opportunity-motivation-behavior with lack of social support (20.1%, 120/596). Multiple logistic regression analysis showed that educational level, smoking history, family history, body mass index, and Charlson Comorbidity Index score were influencing factors of different latent profiles ( P<0.05) . Conclusions:Stroke patients exhibit distinct classifications of capability-opportunity-motivation-behavior. Targeted interventions should be conducted based on the characteristics of each category to improve health behavior management outcomes in patients.

Objective:To explore the mediating effect of rumination between self-perceived burden (SPB) and stigma in stroke patients, so as to provide theoretical basis for the development of targeted nursing interventions in clinical practice.Methods:In September 2022, cluster sampling was used to select 1 126 stroke patients admitted to Department of Neurology of five ClassⅢ Grade A hospitals in Henan Province as subjects. General Information Questionnaire, Self-Perceived Burden Scale (SPBS), Stroke Stigma Scale (SSS), and Chinese Version of Event Related Rumination Inventory (C-ERRI) were used to investigate stroke patients. Pearson correlation analysis was used to explore the correlation between SPB, rumination, and stigma. AMOS 28.0 software was used to establish the structural equation model, and Bootstrap method was used to test the mediating effect.Results:A total of 1 126 questionnaires were distributed, and 1 026 valid questionnaires were collected, with a valid response rate of 91.12% (1 026/1 126). SPBS score of 1 026 stroke patients was (28.68±8.32), the SSS score was (40.53±9.48) and the C-ERRI score was (25.43±12.62). Pearson correlation analysis showed that SPB in stroke patients was positively correlated with stigma and rumination ( P<0.01), and rumination was positively correlated with stigma ( P<0.01). Bootstrap mediating effect test showed that rumination partially mediated the relationship between SPB and stigma in stroke patients, accounting for 55.15% of the total effect. Conclusions:SPB of stroke patients both directly affect stigma and indirectly affect stigma through rumination. Clinical nursing workers should promptly evaluate patients' SPB, pay attention to the mediating role of rumination, develop effective psychological intervention programs, implement personalized and targeted nursing measures, relieve patients' stigma, and improve treatment and rehabilitation compliance.

Objective:To understand the research status and hotspots in the field of stroke health management at home and abroad, and to provide insights for stroke health management research in China.Methods:Relevant literature on stroke health management published between 2013 and 2023 was retrieved from the Web of Science Core Collection and China National Knowledge Infrastructure databases. CiteSpace 6.1.R6 was used for the visual analysis of the number of publications, authors, institutions, countries, and keywords.Results:A total of 382 relevant articles were included, with 169 in English and 213 in Chinese. The number of publications on stroke health management showed a fluctuating upward trend. Research hotspots and frontiers in stroke health management mainly focused on telemedicine, big data and "Internet+", primary and secondary prevention, risk prediction models, quality of life, and swallowing disorders. Future research trends may focus on management models for post-stroke swallowing disorders, risk identification, and the role of caregivers in remote rehabilitation interventions.Conclusions:Researchers can refer to the research hotspots and trends shown by the visual analysis, with particular attention to health management models for patients with post-stroke swallowing disorders and issues related to remote intervention rehabilitation.

Objective To investigate the risk factors of recurrent stroke in IS patients with CHF.Methods A total of 235 elderly IS patients with CHF admitted to Northern Jiangsu People's Hospital from January 2021 to January 2023 were enrolled in this study.According to LVEF clas-sification,they were divided into reduced ejection fraction HF group(HFrEF,LVEF＜40％,80 patients),intermediate ejection fraction HF group(HFmrEF,40％≤LVEF＜50％,57 patients),and preserved ejection fraction HF group(HFpEF,LVEF≥50％,98 patients).After all of them were followed up for 12 months,the patients with recurrent IS were assigned into the recurrent IS group(42 patients)and those without into the non-recurrent IS group(193 patients).Their gener-al data,laboratory results,clinical endpoint events and other indicators were compared in the above groups.Multivariate logistic regression analysis was applied to identify the related risk fac-tors for recurrent stroke in elderly patients with CHF and IS.Results There were significant differences in women ratio,age,history of smoking and drinking,peripheral vascular disease,RBC count,hemoglobin,hematocrit,LDL-C,prothrombin time,international standardized ratio,BNP,LVEF,LVEDD and LVESD among the three groups(P＜0.05,P＜0.01).The recurrent IS group had obviously larger proportion of diabetes mellitus,longer thrombin time,and larger LAD and RAD when compared with the non-recurrent IS group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that diabetes(OR=0.251,95％CI:0.1 96-1.494,P=0.031)and LAD(OR=1.085,95％CI:1.008-1.169,P=0.031)were independent risk factor for recurrent stroke in elderly patients with CHF and IS.There were no significant differences in follow-up period and incidence of clinical endpoints among the three groups(P＞0.05).Conclusion Diabetes and LAD are independent risk factors for recurrent IS in elderly CHF patients with IS.

Malignant tumors of digestive system are highly prevalent malignant tumors that seriously threaten human health around the world. At present, the curative efficacy and prognosis of traditional treatment methods cannot reach the expectation, so it is urgent to find new targets for cancer treatment and realize targeted therapy for tumors. Abnormal energy metabolism in tumor cells is regarded as a hallmark of cancer, and malignant tumor cells absorb glucose through aerobic glycolysis pathway, and obtain a small amount of energy and produce lactate under the catalysis of a series of enzymes. Lactate dehydrogenase A (Lactate dehydrogenase A, LDHA), as a key enzyme in the aerobic glycolysis pathway of tumor cells, plays an important role in the metabolic changes of tumor cells. Studies have demonstrated that LDHA has high expression characteristics in a variety of tumor cells,and its high expression in clinic is often related to the poor prognosis and high metastasis rate of tumors, which is expected to be a new target for cancer therapy. This article reviews the role of LDHA in the development of digestive system tumors and the research progress of related drugs.
