ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

ObjectivesTo investigate the molecular epidemiological characteristics of HIV-1 infection among men who had sex with men (MSM) in Taizhou City, Zhejiang Province, and to provide a scientific reference for acquired immune deficiency syndrome prevention and control efforts. MethodsThe research subjects were all newly reported MSM population in Taizhou City from 2020 to 2023. Blood samples without antiviral therapy were collected. The HIV-1 pol gene was amplified and sequenced, and the sequences were submitted to the Stanford University drug resistance database to identify the mutation sites and drug resistance. MEGA 11.0 software was used to analyze the nucleic acid sequences, construct phylogenetic tree, and calculate genetic distance of gene sequences. The molecular transmission network diagram of HIV-1 was constructed using Cytoscape_v3.10.1, and the influencing factors of network entry were analyzed by logistic regression. ResultsA total of 363 newly reported HIV-infected MSM patients were included, with a median age [M (P₂₅, P₇₅)] of 34 (26,47) years old. The majority had an educational level of junior high school or below (55.65%). A total of eight subtypes were found, mainly CRF07_BC and CRF01_AE. The primary drug resistance rate was 10.47% (38/363). The optimal molecular network gene distance was 0.019, with a network access rate of 42.70% (155/363), and a total of 47 molecular clusters were formed. Multivariate logistic analyses showed that compared with the CRF01_AE subtype, the clustering risk of CRF07_BC subtype was higher (OR=1.916, 95%CI: 1.191‒3.109), cases with drug resistance had a higher risk of cluster formation than those without drug resistance (OR=2.011, 95%CI: 1.006‒4.080), and recent infected patients had a lower risk of entering the largest molecular cluster than long-term infected patients (OR=0.376, 95%CI: 0.137‒0.928). ConclusionThe newly diagnosed infections among the MSM population are active in Taizhou City, Zhejiang Province, with a high level of primary drug resistance. Individuals carrying drug-resistant strains are more likely to cluster. Drug resistance monitoring should be strengthened to prevent further spread of drug-resistant strains in the network.

Objective To establish in vitro the small intestinal organoid culture system and to investigate the effect of lipopolysaccharide(LPS)on the growth of small intestinal organoids and the secretion of inflammatory factors.Methods In vitro,the small intestinal crypt cell mass of C57BL/6 mice was aseptically isolated,collected and embedded in organoid matrix.Under the support of complete medium,the small intestinal organoids with three-dimensional multi-leaf structure with small intestinal epithelioid structure were formed.The small intestinal organoids were subcultured after 5-7 d culture.On the third day after passage,the small intestinal organoids were randomly divided into different mass concentrations of LPS groups(0,150,175,200,225,250,275 and 300 mg/L).After 24 h and 48 h of LPS induction,morphological changes of small intestinal organoid growth and differentiation were observed.CCK-8 method was used to detect the effect of different time points and mass concentrations of LPS on the proliferative activity of small intestinal organoids after induction of inflammation.The effects of four different mass concentrations of LPS(0,175,200 and 225 mg/L)on expression levels of granulocyte-macrophage colony stimulating factor(GM-CSF),interleukin(IL)-1α,IL-6 and IL-10 in organoid culture supernatant at different times were detected by enzyme-linked immunosorbent assay(ELISA).Results The mouse small intestinal organoid culture system was preliminarily constructed.After different time and mass concentration of LPS induced inflammation of small intestinal organoids,it was observed by morphology that small intestinal organoids would have different degrees of expansion and apoptosis in lumen.The proliferation,differentiation and budding of damaged intestinal epithelial crypts or intestinal stem cells were also inhibited to varying degrees,indicating that the growth of small intestinal organoids would be limited to varying degrees after induced inflammation.The proliferation activity of small intestinal organoids decreased to varying degrees after 24 h and 48 h of LPS induction at 175-225 mg/L(P＜0.05),but the cell viability was still greater than 50%.The levels of IL-1α,IL-6 and GM-CSF partially increased after induction with 200 mg/L and 225 mg/L LPS for 24 h and 48 h(P＜0.05).The level of IL-10 decreased after induction with 200 mg/L LPS for 24 h and 48 h(P＜0.05).Conclusion In this study,a model of intestinal inflammatory injury in vitro induced by LPS with different mass concentrations and time points is preliminarily constructed,which provides a more reliable research platform for the mechanism research of intestinal diseases and the screening of effective drugs in the future.

BackgroundSuicidal behavior in adolescence and early adulthood is a major public health concern， and suicide attempts are found to be associated with reasons for living and self-control， whereas there remains a striking lack of empirical research exploring the association among the three in college students. ObjectiveTo explore the relationship among suicide attempts， reasons for living and self-control， and to inform targeted efforts to prevent the development of suicidal behavior. MethodsFrom April to May 2023， a sample of 775 college students from 10 colleges and universities in Shaanxi province， Sichuan province and Chongqing municipality were selected using random sampling method. All students were subjected to complete Self-Control Scale （SCS）， the Reasons for Living Inventory for Adolescents （RFL-A）， and the self-administered Suicide Attempt Questionnaire. Spearman correlation analysis was utilized to examine the correlation among the above scales in students， and mediation analysis was performed using Mplus 8.3. ResultsA total of 738 college students （95.32%） completed the effective questionnaire survey.Suicide attempts were detected in 99 college students （13.41%）. SCS score was positively correlated with RFL-A score （r=0.329， P<0.01）， and SCS score and RFL-A score were both negatively correlated with the risk of suicide attempts （r=-0.194， -0.285， P<0.01）. The indirect mediation effect value of self-control on the relationship between reasons for living and suicide attempts was -0.059 （95% CI： -0.105~-0.018）， accounting for 11.07% of the total effect. There was a gender difference in the mediating effect of self-control， among which the effect was significant in male group， with an indirect effect value of -0.089 （95% CI： -0.163~-0.030） and accounting for 15.72% of the total effect， whereas the mediating effect was not significant in female group （95% CI： -0.407~0.115）. ConclusionReasons for living can negatively predict suicide attempts among college students， and self-control may play a mediating role in the relationship between reasons for living and suicide attempts among college students， and the mediating effect of self-control appears to be statistically significant only in male but not in female students.

Objective: To analyze the relationship between Toll like receptor ( TLR ) 9 and TLR 7 gene polymorphisms among children with hand-foot-mouth disease in a medical institution of Jinan City from 2020 to 2023, so as to provide reference for prevention of hand-foot-mouth disease. Methods: Data of 284 preschool children aged 3-6 with hand-foot-mouth disease, including the season pattern, clinical manifestations, pathogen distribution, were collected in department of pediatric infectious diseases of the Second Children & Women s Healthcare of Jinan from 2020 to 2023. The distribution conditions of TLR 9 and TLR 7 genotypes of enterovirus 71 (EV71) subtype and coxsackievirus A16 (CA16) subtype were compared by Chi square test. Hardy Weinberg equilibrium test was used to characteristic sample population distribution, and Logistic regression analysis in the additive genetic model was adopted to evaluate the relationship between TLR 9 and TLR 7 gene polymorphisms with hand-foot-mouth disease subtype. Results: The time to admission after symptom onset with hand-foot-mouth disease among 284 children was mostly >2-4 d ( 45.42% ), followed by ≤2 d ( 44.72% ). The season pattern was mostly in summer (58.10%). The severity was mostly mild ( 69.72% ), and the main clinical manifestations were skin rash (100.00%) and fever (65.49%). The majority pathogen was EV71 (60.56%). Hardy Weinberg equilibrium test showed good population representation ( P >0.05). Logistic regression analysis was applied to analyze the relationship between TLR9 rs 187084 locus and hand-foot-mouth disease subtypes under the additive genetic model after adjusting for age and gender of the study population, and it was found that compared with those without C allele, each additional C allele increased the risk of CA16 subtype hand-foot-mouth disease by 109% ( OR=2.09, 95%CI =1.13-3.27). Analysis of relationship between TLR 7 rs 3853839 locus and hand-foot-mouth disease subtype showed that compared with those without C allele, the risk of EV71 subtype hand-foot-mouth disease increased by 57% for each additional C allele ( OR=1.57, 95%CI = 1.10 -2.11) ( P <0.05). Conclusions From 2020 to 2023, children with hand-foot-mouth disease in a medical institution of Jinan City is mostly mild and caused by EV71 infection. The polymorphism of rs 3853839 locus of TLR 7 may be related to EV71 infection in children with hand-foot-mouth disease, and the polymorphism of rs 187084 locus of TLR 9 may be related to CA16 infection.

ObjectiveTo analyze the failure of antiretroviral therapy (ART) and drug resistance characteristics among the newly reported HIV-infected patients in Taizhou City from 2020 to 2022. MethodsBlood samples, sociodemographic characteristics and ART information of the newly reported HIV-infected patients who received ART for ≥6 months in Taizhou City from 2020 to 2022 were collected for the detection of recent infections and HIV-1 genotypic drug resistance. Multivariate logistic regression analysis was used to analyze the influencing factors of treatment failure. The gene sequences of cases with failed ART were submitted to the HIV drug resistance database of Stanford University to determine the drug resistance mutation sites and drug resistance characteristics. ResultsAmong the 1 023 newly reported HIV-infected patients receiving ART, the median age （P₂₅，P₇₅） was 47 (33, 58) years, 81.4% were male, 66.4% (679/1 023) were infected through heterosexual transmission, 74.7% had a WHO clinical stage Ⅰ/Ⅱ, 62.2% had a baseline CD4 count of >200 cell·μL^-1, 94.4% (966/1 023) received an immediate ART, and 78.7% were long-term infected. Among the 66 patients with treatment failure (6.5%), the likelihood of treatment failure was lower in those with homosexual transmission (OR=0.39, 95%CI: 0.17‒0.84) and without history of sexually transmitted disease (STD) (OR=0.45, 95%CI: 0.24‒0.92), but higher in those with a baseline CD4 count of ≤200 cell·μL^-1, delayed ART (OR=3.19, 95%CI: 1.24‒7.52), and primary drug resistance (OR=4.69, 95%CI: 1.68‒11.89). Among the 36 HIV-infected patients with virological failure, 27 sequences were successfully amplified, with a successful amplification rate of 75.0% (27/36). The total drug resistance rate was 55.6% (15/27), of which the drug resistance rates of nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs) were 37.0% (10/27), 51.9% (14/27) and 3.7% (1/27), respectively. Among the NNRTIs, the degree of resistance to efavirenz and nevirapine was consistent, with a majority (51.9%) of highly drug-resistant. K103N and M184V were the most common mutation sites, but PIs mutations occured less frequently. A total of 8 genotypes of HIV-1 were detected, in which subtype CRF01_AE accounted for 37.0% (10/27), followed by CRF07_BC [14.8% (4/27)], CRF08_BC [14.8% (4/27)] and subtype C [14.8% (4/27)]. ConclusionDuring the period from 2020 to 2022, the newly reported HIV-infected individuals in Taizhou City were predominated by long-term infections. Immediate initiation of ART can reduce the risk of treatment failure in HIV-infected individuals. Virological treatment failures are primarily associated with resistance to NRTIs and NNRTIs. It is recommended to strengthen active detection and promptly initiate ART to minimize the occurrence of ART failure. Simultaneously, there is a need to intensify drug resistance detection targeted for those with treatment failure, so as to provide a scientific guidance for drug replacement.

ObjectiveTo reveal the influence of Jianchangbang characteristic processing method on the change process of volatile components and the processing mechanism of reducing toxicity and increasing efficiency of Magnoliae Officinalis Cortex（MOC） by studying the changes in the composition and content of volatile components during the processing of ginger processed Xingpo pieces. MethodSamples of raw products， ginger juice moisturized products and stir-fried and heap moisturized products of MOC were taken according to the set time points， and headspace gas chromatography-mass spectrometry（HS-GC-MS） was used to determine the contents of volatile components in the samples， and the relative content of each component was obtained by peak area normalization. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were performed on the sample data using SIMCA 14.1 software， and the differential components during the processing were screened with variable importance in the projection（VIP） value>1 as the indicator. ResultA total of 68 volatile components were identified in the samples， among which some of the chemical components with similar structures showed similar trends of changes， and there was also the phenomenon of interconversion between compounds. Compared with the raw products， the contents of 42 components in ginger juice moisturized products increased， while the contents of 25 components decreased， 19 components were unique， and 4 components were unique to the raw products. Compared with ginger juice moisturized products， MOC in the early stage of piling had three unique components， and the contents of 11 components such as cyclosativene and （+）-α-pinene increased， and the contents of 5 components such as tricyclic terpene and α-curcumene decreased， and ginger juice moisturized products had four unique components. Compared with the early stage of piling， in the later stage， the contents of 8 components such as （+）-α-pinene and camphene significantly increased， while the contents of 6 components such as linalool and α-selinene significantly decreased. During the processing of MOC， there were significant changes in the chemical composition of the samples before and after 20 days. The differences between ginger juice moistening and the early stage of piling， the early stage and the later stage of piling could be clearly distinguished. ConclusionDuring the preparation process of ginger processed Xingpo pieces， the addition of ginger juice can reduce the contents of stimulating components， and the contents of active components continue to increase in several stages， such as the addition of ginger juice， frying and heap moisturizing， the quality of the decoction pieces may change significantly at about 20 d of processing. This study can provide a research basis for exploring the processing mechanism of ginger processed Xingpo pieces.

G protein-coupled receptor (GPR) 40, as one of GPRs family, plays a potential role in regulating glucose and lipid metabolism. To study the effect of GPR40 novel agonist SZZ15-11 on hyperglycemia and hyperlipidemia and its potential mechanism, spontaneous type 2 diabetic KKA^y mice, human hepatocellular carcinoma HepG2 cells and murine mature adipocyte 3T3-L1 cells were used. KKA^y mice were divided into four groups, vehicle group, TAK group, SZZ (50 mg·kg^-1) group and SZZ (100 mg·kg^-1) group, with oral gavage of 0.5% sodium carboxymethylcellulose (CMC), 50 mg·kg^-1 TAK875, 50 and 100 mg·kg^-1 SZZ15-11 respectively for 45 days. Fasting blood glucose, blood triglyceride (TG) and total cholesterol (TC), non-fasting blood glucose were tested. Oral glucose tolerance test and insulin tolerance test were executed. Blood insulin and glucagon were measured via enzyme-linked immunosorbent assay (ELISA). After mice′s execution, liver tissue was harvested to test TG and TC content. Then pathological morphology of liver was observed through hematoxylin-eosin (HE) staining, and the lipid metabolism relative signal pathway was analyzed by Western blot and RT-PCR. The experiments were approved by the Institutional Animal Care and Use Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College. At the same time, Akt phosphorylation level in HepG2 cells and adiponectin in 3T3-L1 cells treated with TNFα were measured with Western blot. The results show that SZZ15-11 not only decreased blood glucose and lipid, improved insulin sensitivity, but also increased fasting blood glucagon and promoted insulin secretion after glucose loading in KKA^y mice. Additionally, SZZ15-11 alleviated hepatic steatosis and liver dysfunction in KKA^y mice. In liver tissue, SZZ15-11 increased AMPKα phosphorylation level and cholesterol metabolism relative gene Abcg8 transcription. In HepG2 cells, SZZ15-11 increased Akt phosphorylation level. In adipocyte 3T3-L1, SZZ15-11 recovered the decreased adiponectin expression by TNFα. This study proved that GPR40 agonist SZZ15-11 could be a candidate compound for regulating glucolipid metabolic disorder.

ObjectiveTo investigate the role and mechanism of action of Yinchenhao Decoction in inhibiting ferroptosis of hepatocytes in mice with autoimmune hepatitis. MethodsA total of 18 specific pathogen-free female C57BL/6 mice were selected and divided into normal group， model group， and treatment group using a random number table， with 6 mice in each group. The mice in the model group and the treatment group were injected with concanavalin A （Con A） via the caudal vein to establish a mouse model of autoimmune hepatitis， and those in the normal group were injected with normal saline. The mice in the treatment group were given prophylactic treatment with Yinchenhao Decoction （4.68 g crude drug/kg） by gavage at 14 days before modeling， and Con A was injected after the last gavage. The levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interferon gamma （IFN-γ）， tumor necrosis factor-α （TNF-α）， iron ion， glutathione （GSH）， reactive oxygen species （ROS）， adenosine triphosphate （ATP）， and malondialdehyde （MDA） were measured； liver index and spleen index were calculated； the expression levels of GPX4 and SLC7A11 were measured； liver histopathological changes were compared between groups. A one-way analysis of variance was used for comparison of normally distributed continuous data between three groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the normal group， the model group had significant increases in liver index， spleen index， ALT， AST， IFN-γ， TNF-α， iron ion， ROS and MDA （all P<0.05） and significant reductions in the content of GSH and ATP and the protein expression levels of GPX4 and SLC7A11 （all P<0.05）. Compared with the model group， the treatment group had significant reductions in liver index， spleen index， ALT， AST， IFN-γ， TNF-α， iron ion， ROS and MDA （all P<0.05） and significant increases in the content of GSH and ATP and the protein expression levels of GPX4 and SLC7A11 （all P<0.05）. HE staining showed that compared with the normal group， the model group showed massive hepatocyte degeneration and necrosis and inflammatory cell aggregation at the portal area， and compared with the model group， the treatment group had alleviation of liver necrosis and inflammatory infiltration. ConclusionLiver injury induced by Con A may be associated with ferroptosis. Yinchenhao Decoction can increase the protein expression levels of SLC7A11 and GPX4 protein and thus inhibit ferroptosis of hepatocytes induced by Con A.
