Objective:To identify genetic etiology of ischemic stroke(IS)based on pleiotropy of obe-sity related genes.Methods:A discordant sib-pair study was designed based on the Fangshan family co-hort in Beijing.Body mass index(BMI)polygenic risk score(PRS)was first constructed under different P values.Using the polygenic transmission disequilibrium test(pTDT),we then compared the actual BMI genetic risk of siblings with IS to their expected risk,to analyze whether higher BMI was over-trans-mitted to siblings with IS.The single nucleotide polymorphism(SNP)that comprised the PRS over-trans-mitted with IS and that corresponded to the highest heritability of IS were identified as a pleiotropy SNPs set between BMI and IS.This set was then utilized as a candidate set to identify and verify risk SNPs as-so-ciated IS by transmission disequilibrium test.Finally,we identified independent genomic risk loci and mapped to genes,we then explored the biological function of the identified risk loci and genes by func-tional annotation and pathway enrichment.Results:A total of 541 participants were enrolled,with an average age of(58.4±8.1)years,including 326 discordant sib pairs of ischemic stroke.Compared with non-IS participants,IS participants with males,education level below junior high school,hypertension and hyperlipidemia accounted for a higher proportion(P＜0.05).For all the BMI PRS,we found that the actual genetic risk of BMI in siblings with IS was higher than their expectation,suggesting that genetic risk associated with high BMI was over-transmitted with IS.Compared with other SNP sets,the set(P＜5 × 10-4)corresponded to the best analytical statistics of pTDT and the highest heritability of IS and was identified as the pleiotropy SNP set between BMI and IS.Within this set,there were 45 SNPs having linkage and association with IS,which were located in 43 independent genomic risk loci and mapped to 40 genes.These genes were significantly enriched in the lipid metabolism pathway.The rs2232852 cor-rected by multiple tests was mapped to CYB5R1 and ADIPOR1,which were related to lipid metabolism and the ferroptosis pathway.Conclusion:Pleiotropy between BMI-related genes and IS was observed.Forty-five SNPs were found with linkage and association with IS in the pleiotropy gene set and mapped to 40 genes,which were functionally enriched in lipid metabolic pathways.The rs2232852 corrected by multiple tests during association analysis validation was mapped to CYB5R1 and ADIPOR1,which were related to lipid metabolism and the ferroptosis pathway,suggesting that lipid metabolism and ferroptosis played an important role in the development of IS.

Objective To investigate the protective effect of Notch1-regulated microglial polarization against epileptic seizure in mice.Methods The pentylenetetrazole(PTZ)kindling models of epilepsy were established in mice with normal(Notch1normal)and high(Notch1over)expression of the Notch1 protein,with Racine grade Ⅳ set as the standard,to evaluate the effect of Notch1 expression on sei-zure susceptibility.Microglial activation and polarization in the temporal lobe tissues of mice were detected using immunofluorescence staining,and the levels of inflammatory cytokines in the temporal lobe tissues was detected using an enzyme-linked immunosorbent assay.Results High Notch1 expression showed high resistance to seizures.Compared with the Notch1normal+Sal group,the relative fluorescence intensity of Iba1,CD16,and Arg1 proteins in the temporal lobes of mice in the Notch1normal+PTZ group,as well as the TNF-α,IL-6,and IL-10 levels significantly increased(P＜0.05).Compared with the Notch1nornal+PTZ group,the relative fluorescence intensity of Iba1 and CD16 proteins in the temporal lobes of mice in the Notch1over+PTZ group significantly decreased(P＜0.05),the relative fluorescence intensity of Arg1 protein significantly increased(P＜0.05),the TNF-α and IL-6 levels significantly decreased(P＜0.05),and the IL-10 level further increased(P＜0.05).Conclusion High Notch1 protein expression significantly enhanced M2-type microglial polari-zation,inhibited M1-type microglial polarization,and increased resistance to seizure susceptibility in mice.

Objective To address the challenges of constructing large language models for traditional Chinese medicine(TCM)classics,which are complex and expensive to fine-tune,this study explores a lightweight fine-tuning method for such models,aiming to develop a question-answering model centered on TCM classics,particularly various editions of Shang Han Lun through the ages.Methods Dataset construction involved designing prompts to guide GPT-4 in generating Q&A pairs based on Shang Han Lun and integrating them with the ShenNong_TCM_Dataset and cMedQA2 datasets.Five general-purpose large models were selected for Lora fine-tuning.The best model was chosen through evaluation,and the performance of multiple quantized versions was validated.Results After fine-tuning,the BLEU,ROUGE-1,ROUGE-2,and ROUGE-L metrics for the Qwen-7B-Chat model improved by 17.61,19.63,14.3,and 21.4,respectively,compared to the base model.Conclusion The selected model in this study is capable of effectively understanding and utilizing professional terms and concepts from TCM classics,such as Shang Han Lun,to provide accurate answers to user queries.Compared to similar models,it requires lower fine-tuning costs and computational power,contributing to the dissemination of TCM knowledge and the development of intelligent systems.

Yigongsan， derived from QIAN Yi’s Key to Therapeutics of Children’s Diseases in the Song Dynasty， is a classic pediatric prescription that is included in the Catalogue of Ancient Classic Prescriptions （the Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine in 2022. This paper verifies and analyzes the historical origin， composition， dosage， processing， decoction method and efficacy of Yigongsan by systematically combing ancient books and modern documents. As a result， Yigongsan is composed of five herbs： Panax ginseng， Poria cocos， Atractylodes macrocephala， Citrus reticulata and Glycyrrhiza uralensis， of which P. cocos should be peeled， A. macrocephala is fried with soil， G. uralensis is roasted with honey while P. ginseng and C. reticulata are raw products. According to the dosage of ancient and modern times， each medicinal herb must be ground into fine powder， 1.6 g for each， added with 300 mL of water， 5 pieces of Zingiber officinale， and 2 Ziziphus jujuba， decocted together to 210 mL， and taken before meals. In ancient books， Yigongsan is used to treat vomiting， diarrhea， spleen and stomach deficiency， chest and abdominal distension， and lack of appetite， etc. Modern research showed that Yigongsan could also be used in the diseases of immune system， respiratory system， blood system， etc.， involving infantile anorexia， asthma， anemia， tumors and so on.

Objective:To carry out the scoping review on the form, function and application effect of decision aids for breast reconstruction of breast cancer patients, so as to provide reference for domestic research on decision aids for breast reconstruction.Methods:According to the scoping review framework, literature was systematically searched on Web of Science, PubMed, Cochrane Library, Embase, Scopus, CINAHL, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc. The retrieval period was from the establishment of the database to January 19, 2024.Results:A total of 14 articles were included, including 8 randomized controlled trials (RCT), four quasi-experimental studies, one qualitative study, and one prospective cohort study. The main forms of decision aids included web-based software programs, mobile applications (APP), decision support groups, or decision support manuals. The evaluation of intervention effectiveness mainly involved indicators such as patient decision regret, decision conflict, satisfaction, acceptance, and patient-reported outcomes.Conclusions:Breast reconstruction decision aids have a certain positive impact on improving patient satisfaction, decision quality, and patient-reported outcomes, but most studies have not examined their long-term effects. The research on decision aids for breast reconstruction in China is still in its infancy. It is suggested that future research should draw on relevant foreign studies to develop and advance high quality and diversified decision aids, and promote their clinical applications.

Objective To explore the early prediction value of related test indicators for non-biliary acute pancreatitis and the influence of interaction of related test indicators on non-biliary acute pancreatitis.Methods A total of 280 patients with the first onset of non-biliary acute pancreatitis who were hospitalized in Jinshan Hospital of Fudan University from July 2019 to July 2023 were divided into mild group and severe group.The severe group included moderately severe and severe patients.Clinical data,tests and examination indicators of first-attack inpa-tients within 48 hours after admission were collected.Through logistics regression analysis,early detection indica-tors related to the severity of non-biliary acute pancreatitis were explored,and the influence of their interaction was studied.Results Single-factor analysis showed that albumin(ALB),thyroxine(T4),serum free triiodothyronine,albumin(ALB),Thyroxine(T4)in both groups.FT3),thyroid stimulating hormone(TSH),serum triglyceride(TG),calcium(Ca)and other indicators were statistically significant(P<0.05);Through multi-factor logistics regression analysis,it was found that the OR values of T4,FT3,TSH,CA and other detection indicators were all less than 1(P<0.05);After controlling for gender,age,history of hypertension,history of diabetes and other factors,the interaction between TG and HbA1c was analyzed,the aOR was 1.500 when only HbA1c was increased(P>0.05),the aOR was 4.488 when only TG was increased(P<0.05),and the aOR was 5.084 when TG and HbA1c were increased simultaneously(P<0.05).Conclusion ALB,T4,FT3,TSH,CA were protective factors of non-biliary AP,and could be used as predictive indicators of the severity of non-biliary acute pancreatitis.Inter-action of HbA1c with TG increases the risk of progression to severe non-biliary acute pancreatitis.

Objective To explore the effect of Traditional Chinese Medicine's five-element music therapy com-bined with individualized emotional counseling intervention in patients with autoimmune liver disease of liver de-pression and spleen deficiency type.Methods 74 patients with autoimmune liver disease of liver depression and spleen deficiency type who were admitted to the hepatology department of a tertiary hospital from January 2021 to February 2022 were selected as research subjects,and they were divided into an experimental group and a control group by a random number table with 37 cases in each group.The control group was given routine treatment and nursing care,as well as Traditional Chinese Medicine's emotional nursing.The experimental group received Tradi-tional Chinese Medicine's five-element music therapy combined with individualized emotional counseling intervention on the basis of routine treatment and nursing care,with an intervention period of 4 weeks.The Generalized Anxiety Disorder Scale(GAD-7),Patient Health Questionnaire Depression Scale(PHQ-9)and Pittsburgh Sleep Quality Index(PSQI)were used to evaluate patients within 24 hours after admission and after 4 weeks of intervention.Results A total of 72 patients completed the study,with 36 in the experimental group and 36 in the control group.Before and after intervention,the scores of GAD-7,PHQ-9,and PSQI in the experimental group were compared,and the dif-ferences were statistically significant(P＜0.001).After the intervention,the GAD-7 score in the experimental group was(7.89±3.15),which was lower than(10.14±4.41)in the control group.The PHQ-9 score was(12.33±4.08)in the ex-perimental group,which was lower than(14.64±5.34)in the control group.The PSQI score was(12.39±3.06)points,which was lower than(14.22±3.37)in the control group,and the differences were statistically significant(P＜0.05).Conclusion The application of Traditional Chinese Medicine's five-element music therapy combined with individual-ized emotional guidance intervention can effectively improve the sleep quality and help alleviate negative emotions in patients with liver depression and spleen deficiency type of autoimmune liver disease.
