ObjectiveTo explore the correlation between the occurrence of cardiovascular events in rheumatoid arthritis（RA） and traditional Chinese medicine（TCM） syndrome. MethodsThe cross-sectional study selected 6713 RA patients from 122 centres nationwide， in which general information such as name， gender， age， height， body weight， and course of disease were collected by completing a questionnaire； patients were classified into eight types of syndrome according to the information of their four examinations，i.e. wind-dampness obstruction syndrome， cold-dampness obstruction syndrome， dampness-heat obstruction syndrome， phlegm-stasis obstruction syndrome， stasis-blood obstructing collateral syndrome， qi-blood deficiency syndrome， liver-kidney insufficiency syndrome， and qi-yin deficiency syndrome. According to the occurrence of cardiovascular events， they were divided into the occurrence group and the non-occurrence group， and the condition assessment data and laboratory examination indexes were recorded. The test of difference between groups was used to analyse the possible risk factors for the occurrence of RA cardiovascular events， and binary logistic regression was used to analyse the correlation between TCM syndromes and RA cardiovascular events. ResultsA total of 6713 RA patients were included， including 256 cases in occurrence group and 6457 in non-occurrence group. There was no statistically significant difference between groups in terms of height， gender， insomnia， appetite， white blood cell（WBC）， hemoglobin（HGB）， platelets（PLT）， rheumatoid factor（RF）， anti-cyclic peptide containing citrulline（CCP）， alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， γ-glutamyl transpeptidase（GGT）， urea creatinine（CREA）， and glucose（GLU）（P＞0.05）. The TCM syndromes between groups showed significant statistic differences（P＜0.05）. Patients in occurrence group had longer disease duration， heavier body weight， and older age； more severe conditions such as disease activity（DAS-28）， number of painful joints（TJC）， number of swollen joints（SJC）， health questionnaire scores（HAQ）， visual analog scores（VAS）， restlessness， and fatigue； higher blood sedimentation rate（ESR）， low-density lipoprotein（LDL-C）， triglyceride（TG）， total cholesterol（TC）， D-Dimer， and lower high-density lipoprotein（HDL-C）（P＜0.05）. The distribution of syndrome types showed that dampness-heat obstruction syndrome accounted for the largest proportion of patients in both groups and was higher in RA cardiovascular events. Logistic regression analysis showed that the occurrence of RA cardiovascular events was strongly associated with dampness-heat obstruction syndrome［OR=5.937， 95%CI （4.434， 7.949）， P＜0.001］. ConclusionThe occurrence of RA cardiovascular events were associated with TCM syndromes， and the probability of cardiovascular events in the RA patients with dampness-heat obstruction syndrome was 5.937 times higher than patients with other TCM syndromes.

Objective:To assess the impact of reducing the mesh density on the overall volume and trueness of single-crown restora-tions.Methods:15 single-crown restorations were included,and their mesh density in 3D software was simplified by 75％,50％,25％,10％and 5％respectively.The overal volume,file size and mesh edge length of the restorations with different reduction levels were compared.Deviation analysis was conducted by curving clipping the area of the shoulder,tissue surface(except for the shoulder)and occlusal surface of the restorations and compared with those of the corresponding regions in the non-simplified restorations.Trueness was assessed using the root mean square(RMS)values for the volume and trueness of different areas.Results:Reducing the mesh den-sity did not significantly affect the overal volume of the single-crown restorations(P＞0.05),but it had a significant impact on the file size(P＜0.001),mesh edge length(P＜0.001)and the trueness of the shoulder(P＜0.001),tissue surface(except for the shoulder)(P＜0.001)and occlusal surface(P＜0.001)areas.Conclusion:Reducing the mesh density had little impact on the overall volume of the restorations but significantly affected their trueness.

Objective This study aimed to investigate the factors influencing the personal burden rate incerebral ische-mic patients,compare the difference in the burden rate among the patients with varying degrees of cerebral ischemia,provide a reference for establishing a personal burden rate evaluation,and propose suggestions for control its increase.Methods The medi-cal insurance data were collected from 8164 discharged patients in a tertiary hospital in Tianjin between January and December 2022.With the data,the Generalized Linear Model was utilized to analyze the factors affecting the personal burden rate across different Diagnosis Related Groups(DRGs).Results Statistically significant differences were observed in the cost structure a-mong different DRGs.Age,length of hospital stays,total hospitalization cost,hospital admission mode,number of hospitaliza-tions,and type of medical insurance significantly impacted the personal burden rate.The personal burden rate was inversely cor-related with age and length of hospital stays,but directly correlated with the total hospitalization cost.The patients admitted from emergency,first-time hospitalization,and those covered by the basic medical insurance program for urban employees had a lower personal burden rate.Conclusion Hospitals should establish diverse personal burden rate performance evaluation standards for patients with different types of medical insurance,incorporating factors such as average length of hospital stays and average hospi-talization cost.A more equitable hospital internal assessment plan should be developed by considering patients admitted to differ-ent departments and aligning with the characteristics of clinical pathways.Medical institutions should minimize self-funded pro-jects under declared medical insurance,increase the enrollment of cases in DRGs,and promote tiered diagnosis and treatment to reduce the personal burden rate for patients.

ObjectiveTo evaluate the clinical efficacy and safety of Tripterygium wilfordii polyglycoside tablets （TWP） in the treatment of rheumatoid arthritis （RA） in the real world. MethodDiagnosis and treatment data of patients with RA in Chinese medicine rheumatology registration research information platform information database （CERTAIN） from January 1，2019 to January， 2024 were collected. According to the inclusion and exclusion criteria， data were screened. The included data were divided into an exposure group and a control group according to the use of TWP or not. Propensity score matching （PSM） was used in both groups to keep the baseline balanced and comparable. The disease activity score （DAS28-ESR） of 28 joints based on the erythrocyte sedimentation rate （ESR）before and after treatment was compared between the two groups， as well as health assessment questionnaire （HAQ），visual analogue scale （VAS），tender joint count （TJC），swollen joint count （SJC）， patient's global assessment （PGA），evaluator's global assessment （EGA），laboratory indexes， clinical curative effect， and adverse reactions. ResultA total of 3 978 patients were included，including 929 in the exposure group and 3 049 in the control group. Before PSM，there were significant differences in demographic information，DAS28-ESR score，PGA，EGA，HAQ，VAS scores，SJC， and TJC between the two groups （P<0.05）. After successful PSM matching，922 patients in the exposure group and 922 patients in the control group were included. There was no significant difference in demographic information and DAS28-ESR between the two groups before treatment，and the differences in other indexes between the two groups decreased to varying degrees. After treatment，the DAS28-ESR，PGA，EGA，HAQ，SJC，TJC，VAS scores， ESR，and IgG immune index of the two groups were significantly lower （P<0.01）. Compared with those in the control group after treatment，the DAS28-ESR，PGA，EGA，HAQ，VAS scores， and ESR in the exposure group after treatment decreased more significantly （P<0.05，P<0.01）. There was no significant difference in TJC in the exposure group after treatment. However， TJC in the exposure group was significantly higher than that in the control group before treatment （P<0.05）. In terms of TJC reduction，the exposure group performed better than the control group. There was no significant difference in SJC and IgG between the exposure group and the control group after treatment. After treatment，the clinical symptoms of poor appetite，insomnia and many dreams，upset，fatigue，and fear of wind and cold in the two groups were improved. Except that the proportion of women in the exposure group was higher than that in the control group （P<0.01），there was no significant difference in the incidence of other adverse reactions between the two groups after treatment. ConclusionTWP to treat RA can effectively reduce DAS28-ESR，PGA，EGA，HAQ，TJC，and VAS scores and improve the general symptoms. Except for the women at childbearing age with fertility requirements that TWP is not applicable，it shows good security.

Objective Explore changes in polysaccharides in Jiangxiangru before and after ginger juice preparation,and evaluate polysaccharide anti-inflammatory and antioxidant activities before and after processing.Methods The contents of Jiangxiangru polysaccharide(JXRPs)and Ginger juice processed of Jiangxiangru polysaccharide(JZJXRPs)before and after processing were determined by phenol-sulfuric acid method.We used the swelling model in rats and endotoxin(LPS)to establish the RAW264.7 mouse macrophage inflammation model.The optimal administration concentration was determined using a cell proliferation(MTT)assay.Enzyme-linked immunosorbent assay(ELISA)were used to measure Interleukin-6(IL-6),Interleukin-12(IL-12),Nitric oxide(NO),Interleukin-4(IL-4),and Interleukin-10(IL-10).Bleeding time of mice by tail cutting was observed to evaluate the hemostatic effect.The ability to remove 1,1-diphenyl-2-picryl-hydrazyl radical(DPPH)and 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate)(ABTS)was used to evaluate in vitro antioxidant activity.Results The contents of JXRPs and JZJXRPs were 13％and 22％,respectively.In swollen rats at 4 h after injection,compared with the model group,200 mg/kg JXRPs and 100 mg/kg JZJXRPs significantly reduced rat swelling(P＜0.05).In vitro anti-inflammation assessment showed that the polysaccharides before and after processing significantly inhibited secretion of IL-6,IL-12,and NO(P＜0.01)and promoted secretion of IL-4 and IL-10(P＜0.01),and also that processing post-effects were stronger.The hemostatic experiment show that,compared with the control group,JXRPs increased hemostasis,but without a significant difference,and no significant difference was found using JZJXRPs,although high doses showed a trend to increase hemostasis.In vitro antioxidant activity showed that JXRPs and JZJXRPs had different scavenging abilities for DPPH and ABTS with IC50 values of JXRPs of 0.2215 and 0.2110 mg/ml,respectively,and IC50 values of JZJXRPs of 0.1651 and 0.1884 mg/mL,respectively.Conclusions After Jiangxiangru is produced in ginger juice,it promotes dissolution of polysaccharides and increases polysaccharide content.Anti-inflammatory,hemostasis,and antioxidant capacities are stronger in JZJXRPS than JXRPS,which lays the foundation for follow-up research and clinical applications of JXRPS.

A skill assessment tool for laparoscopic left lateral sectionectomy skills was constructed consisting of 5 primary indicators and 23 secondary indicators. AHP analysis showed that the concordance rate of each matrix of the secondary indicators was <0.1, meeting the consistency test requirements. Conclusions:The assessment tool for laparoscopic left lateral sectionectomy skills developed in this study is objective and reliable for evaluating the surgical skills of novice surgeons.

Objective To investigate the effects of MCSO on physiological behavior and antioxidant index in D.melanogaster.Methods One-day-old wild type D.melanogaster was divided into control group,0.25％,0.5％,1％,2％and 4％dose groups,as well as male and female groups.The control group was exposed to the base medium,and each dose group was exposed to the MCSO medium added with 0.25％,0.5％,1％,2％and 4％concentrations,respectively.The optimal dosage concentration and time of administration were investigated by climbing experiment.Then the flies were divided into control group,model group and MCSO group.The model group was established by depriving the flies of sleep through repeated nocturnal light stimulation.Period of drug treatment,appetite test,negative geotaxis ability test,stress test,olfactory memory test,and sleep-wake rhythm detection were used to explore the effects of MCSO on their physiological behavior.The activities of super oxidase dismutase(SOD),catalase(CAT),and malondialdehyde(MDA)were detected by enzyme-linked immunosorbent assay.Results MCSO enhanced the locomotory ability of 30-day-old D.melanogaster(P＜0.01),increased the activity of SOD and CAT(P＜0.01),and decreased the concentration of MDA(P＜0.01).Improve olfactory memory of senile fruit flies.After sleep deprivation,the night sleep time of female Drosophila model group was reduced(P＜0.05),and that of male Drosophila model group was reduced(P＜0.01).After feeding MCSO,the night sleep time of female drosophila model group was extended(P＜0.05),and that of male drosophila model group was extended(P＜0.01).Conclusions MCSO had a certain antioxidant effect,prolonging the sleep time and improving the olfactory memory of sleep-deprived Drosophila.

Objective:To analyze the efficacy and safety of FOLFOX-hepatic arterial infusion chemotherapy (HAIC) combined with targeted immunotherapy for initial unresectable hepatocellular carcinoma.Methods:A retrospective analysis was conducted on the data of initial unresectable hepatocellular carcinoma patients who visited Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from June 2022 to June 2023. A total of 51 patients were enrolled, including 47 males and 4 females, with the age of (56.1±10.7) years. All 51 patients received HAIC combined with immune targeted therapy. After each HAIC combined with immune targeted therapy, the efficacy was evaluated according to the modified response evaluation cirteria in solid tumor (mRECIST). Objective response rate and disease control rate were calculuted. The conversion surgery rate and adverse events during treatment were recorded. Follow up patients' disease progression and survival status, and meanwhile analyze prognosis.Results:According to mRECIST assessment, the number of patients with complete remission, partial remission, disease stability, and disease progression were 4 (7.8%), 27 (52.9%), 14 (27.4%), and 6 (11.8%), respectively. The disease remission rate was 60.8%(31/51), and the disease control rate was 88.2%(45/51). After HAIC combined with immune targeted therapy, 13 patients underwent liver cancer resection, with a surgical conversion rate of 25.5%(13/51). The median progression free survival of 51 patients was 14.2 months, and the median overall survival has not yet been reached. The progression free survival rates of 51 patients at 6 and 12 months were 90.2% and 64.7%, respectively, and the cumulative survival rates at 6 and 12 months were 100% and 86.3%, respectively. During the treatment period, all patients experienced various degrees of adverse reactions, 38(75.5%) patients were grade 1-2 adverse accidents, which could be relieved and controlled after corresponding treatment.Conclusion:FOLFOX-HAIC combined with targeted immunotherapy provides an effective and safe treatment option for unresectable hepatocellular carcinoma, offering surgical resection opportunities for unresectable hepatocellular carcinoma patients.

Objective:To analyze the clinical characteristics and prognostic factors of high-risk neuroblastoma (HR-NB) patients with skeletal metastasis.Methods:The clinical features of 336 newly treated HR-NB patients with skeletal metastases admitted to the Department of Medical Oncology of Beijing Children′s Hospital, Capital Medical University from January 2007 to December 2018 were analyzed retrospectively.Kaplan-Meier method was used for the survival analysis, and Log- Rank test was used for univariate prognosis analysis.The Cox model was used to analyze the multifactorial prognostic analysis. Results:A total of 336 HR-NB patients were recruited, involving 188 males and 148 females with the median age of onset of at 43 (4-148) months.Skeletal metastases affected the viscerocranium (89 cases, 26.5%), neurocranium (193 cases, 57.4%), vertebrae (298 cases, 88.7%), sternum and ribs (183 cases, 54.5%), pelvis (270 cases, 80.4%), upper limbs (182 cases, 54.2%) and lower limbs (240 cases, 71.4%). The 5-year event-free survival (EFS) rate and overall survival (OS) rate were (30.4±2.7)% and (41.3±2.9)%, respectively.Univariate analysis showed a significantly lower 5-year OS rate in skeletal metastatic HR-NB patients with poor prognostic classification, the morphology of neuroblastoma (stroma-poor) and ganglioneuroblastoma (intermixed), high index of mitosis-karyorrhexis index, lactate dehydrogenase≥587 U/L, serum ferritin≥92 μg/L, MYCN amplification and 1p loss of heterozygosity, and metastases in the viscerocranium, neurocranium, vertebrae, sternum and ribs, pelvis, upper limbs and lower limbs (all P<0.05). The 5-year OS rate of HR-NB patients with all 7 regions of skeletal metastases was only (14.2±5.9)%, which was significantly lower than that in patients with a single region metastasis or multi-region metastases[(66.0±10.2)% vs.(43.6±3.4)%, χ2=45.722, P<0.05]. Cox multifactorial analysis showed that MYCN amplification ( HR=4.165, 95% CI: 2.356-7.363) and the viscerocranium metastasis ( HR=2.560, 95% CI: 1.519-4.315) were the independent risk factors affecting the prognosis of HR-NB patients with skeletal metastases (all P<0.05). Conclusions:The prognosis is extremely poor in HR-NB patients with multiple skeletal metastases at the initial diagnosis.The amplification of MYCN and the viscerocranium metastasis are the poor prognostic factors for HR-NB patients with skeletal metastases.
