ObjectiveTo investigate the risk factors for atherosclerosis （AS） in rheumatoid arthritis （RA） patients and its correlation with traditional Chinese medicine （TCM） syndromes. MethodsA cross-sectional study was conducted， enrolling 16,082 RA patients from 122 medical centers nationwide. Patient demographics， disease assessment data including disease activity （DAS-28）， tender joint count （TJC）， swollen joint count （SJC）， patient's global assessment （PGA）， evaluator's global assessment （EGA）， and visual analogue scale （VAS）， major clinical symptoms including insomnia， loss of appetite， irritability， and fatigue， and laboratory indicators including blood routine， inflammatory markers， liver and kidney function， metabolic indices， and coagulation markers were collected through questionnaire. Based on the four examinations in TCM， patients were classified into eight TCM syndromes， which were wind-damp obstruction， cold-damp obstruction， damp-heat obstruction， phlegm-stasis obstruction， blood stasis obstructing the collaterals， qi-blood deficiency， liver-kidney insufficiency， and qi-yin deficiency. Patients who experienced AS events were included in the event group （564 cases）， while those without AS events were included in the non-event group （15,518 cases）. Intergroup difference tests were used to screen potential risk factors， and binary logistic regression analysis was employed to assess the correlation between TCM syndromes and rheumatoid arthritis with atherosclerosis （RA-AS）. ResultsCompared to the non-event group， patients in the event group had longer disease duration， higher body weight， and older age （P＜0.05）， and showed significantly higher DAS28， TJC， SJC， PGA， EGA， VAS， ESR， low-density lipoprotein cholesterol （LDL-C）， triglycerides （TG）， total cholesterol （TC）， and D-dimer levels， and lower high-density lipoprotein cholesterol （HDL-C）， with more severe symptoms of insomnia， irritability， and fatigue （P＜0.05）. Damp-heat obstruction syndrome was the most prevalent in both groups， with a higher proportion in the event group （393/564， 69.68%） than in the non-event group （4578/15,518， 29.50%） showing significant difference （P＜0.05）. Logistic regression analysis showed that patients with damp-heat obstruction syndrome had a 5.326-fold higher risk of developing RA-AS compared to those without this syndrome （OR=5.326， 95%CI 4.517 to 7.089， P＜0.001）. ConclusionThe occurrence of RA-AS is associated with TCM syndromes， disease activity， inflammatory markers and lipid metabolic indices， and damp-heat obstruction syndrome is an independent risk factor for RA-AS.

Objective:To establish a stable rat model of sequelae of pelvic inflammatory disease(SPID)with clinical characteristics,and to provide a reliable experimental model for the study of the pharmcological effect and mechanism of SPID.Methods:Twenty-four 7-week-old SD rats were divided into sham operation group,model-A(108 cfu/mL mixed bacterial solution,0.2 mL),model-B(109 cfu/mL mixed bacterial solution 0.2 mL),and model-C(108 cfu/mL E.coli 0.2 mL).The weight of the rat's uterine was weighed and the uterine index was calculated.The automatic hematology analyzer was used to detect the blood routine;hematoxylin-eosin staining(HE)and masson staining were used to detect uterine pathlogical changes in rats.Enzyme-linked immunosorbent assay(ELISA)was used to detect interleukin-1β(IL-1β),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in rat uterine tissue homogenates.Western blot was used to detect the expression of proteins related to NF-κB signaling pathway.Results:Compared with the sham operation group,the uterine index of model-A,model-B,and model-C were significantly increased(P＜0.05,P＜0.01).The levels of WBC and NE in the model-A increased significantly(P＜0.01).The level of LY in model-B decreased significantly(P＜0.01).The levels of IL-1β,TNF-α in model-A,model-B,and model-C were significantly increased(P＜0.01).The levels of IL-6 in model-A and model-B were significantly increased(P＜0.05,P＜0.01).The collagen volume fraction of model-A and model-B were significantly increased(P＜0.01).Mechanism study indicates that the expression levels of p-IKKβ/IKKβ,p-IκBα/IκBα and p-p65/p65 in model-A were significantly increased(P＜0.01),and the expression levels of IκBα/β-actin were significantly decreased(P＜0.01).The expression level of p-IKKβ/IKKβ in model-B was significantly increased(P＜0.01).Conclusions:A stable rat model of SPID that conforms to clinical characteristics can be successfully constructed by combining 0.2 mL of mixed bacterial solution with a concentration of 108 cfu/mL and mechanical injury.This modeling method intervened in the expression of the NF-κB inflammatory signaling pathway.

Objective To explore the application of goal-directed fluid therapy based on pulse pressure variation rate(PPV)combined with low central venous pressure(LCVP)technique in liver surgery.Methods A total of 86 patients who underwent liver lobe/segment resection in our hospital from January 2022 to December 2023 were included,and randomly divided into two groups by random sequence method.Patients in the conventional group were treated with LCVP technique,while patients in the test group were given PPV goal-directed intervention on the basis of the conventional group.The surgical indicators,hemodynamic indicators,cognitive function,adverse reactions and recovery of gastrointestinal function of patients in the two groups were compared.Results There was no statistically significant difference in the operation time,Pringle maneuver time,first postoperative exhausting time or first postoperative defecation time of patients between the two groups(P>0.05).However,the intraoperative blood loss,intraoperative fluid infusion volume and hospital stay of patients in the test group were all less/shorter than those in the conventional group(P<0.05).Compared with the time point of T0,patients in the two groups showed increased heart rate(HR)but decreased mean arterial pressure(MAP)and central venous pressure(CVP)at time points of T1 and T2(P<0.05).There was no statistically significant difference in the HR or MAP of patients between the two groups at time points of T0,T1,T2 and T3(P>0.05).At time points of T1 and T2,the CVP of patients in the test group was lower than that in the conventional group(P<0.05).One day after operation,the mini-mental state examination(MMSE)score of patients in the test group was higher than that in the conventional group(P<0.05).The MMSE scores 7 days after operation of patients in the two groups were higher than those 1 day after operation(P<0.05).Patients in the test group had a lower total incidence of adverse reactions and a shorter recovery time of gastrointestinal function than those in the conventional group(P<0.05).Conclusion The goal-directed fluid therapy based on PPV combined with LCVP technique has a good application effect in liver surgery,which can reduce intraoperative blood loss and fluid infusion volume of patients,shorten hospital stay,increase hemodynamic stability,improve postoperative cognitive dysfunction,and promote the recovery of gastrointestinal function,with a relatively high treatment safety.

Objective To analyze the association between lifestyle and the risk of type 2 diabetes(T2D)among adult residents.Methods The data was sourced from the Shanghai Suburban Adult Cohort and Biobank.A total of 42 096 adult residents who had not developed T2D were recruited from four districts of Shanghai(Songjiang,Jiading,Minhang,and Xuhui)between 2016 and 2019.The follow-up ended on Feb 28,2023.A structured questionnaire was used to collect information on six lifestyle-related items,including smoking,alcohol consumption,BMI,waist circumference(WC),physical activity,and diet.The unhealthy lifestyle scores(UHLS)were calculated by counting the number of all the unhealthy lifestyle items,with a range of 0-6.New-onset T2D events diagnosed by physicians were obtained through the medical information system.Cox proportional hazards regression model and restricted cubic spline model were utilized to evaluate the association between unhealthy lifestyles and the risk of T2D incidence.Results About 28.1%of the participants led 4-6 unhealthy lifestyles.A total of 1 752 new T2D cases were identified during 218 513.4 person-years of follow-up.Analysis of single unhealthy lifestyle showed that abnormal WC(HR=1.5,95%CI:1.4-1.7)and abnormal BMI(HR=1.3,95%CI:1.2-1.5)were associated with an increased risk of T2D.Compared with individuals with a UHLS of 0-1,those with a UHLS of 3 and 4-6 had 30%(95%CI:1.1-1.6)and 50%(95%CI:1.2-1.8)higher risks of T2D,respectively.Each additional unhealthy lifestyle was associated with a 10%increase in T2D incidence risk(HR=1.1,95%CI:1.1-1.2).Conclusion The risk of T2D in adult residents increases with the cumulative number of unhealthy lifestyles.Adult residents with abnormal WC or BMI,or have three or more unhealthy lifestyles accumulated,will increase the risk of new-onset T2D.

We reported the clinical,imaging,and treatment process of a patient with severe cranial penetrating injury caused by a nail from a nail gun that accidentally shot into the eye and penetrated into the skull while working.The patient was admitted to the Qingpu Branch of Zhongshan Hospital,Fudan University after being injured by the nail gun.The patient was admitted to the hospital 1 hour after injury with coma.After admission,the foreign body was completely removed and part of the hematoma was cleared through emergency surgery.After surgery,there were high-risk complications such as cerebral edema peak,intracranial hypertension,intracranial infection,cerebrospinal fluid leakage,and intracranial pseudoaneurysm.The patient eventually regained consciousness and was transferred to rehabilitation treatment.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

Background and Aims:Body mass index(BMI),an important indicator of nutrition and health,is closely associated with postoperative complications.This study was performed to investigate the relationship between preoperative BMI and severe complications in patients undergoing liver resection for hepatolithiasis,aiming to provide preoperative guidance for clinicians,reduce the risk of postoperative complications,and ensure surgical safety and efficacy.Methods:The clinical data of 484 patients with hepatolithiasis who underwent liver resection between May 2006 and December 2022 at the First Affiliated Hospital of Army Medical University and Beijing Tsinghua Changgung Hospital were retrospectively collected.Patients were classified into low BMI group(≤18.4 kg/m2),normal BMI group(18.5-24.9 kg/m2),and high BMI group(≥25.0 kg/m2)based on preoperative BMI.Baseline characteristics,overall complications,severe complications,and other postoperative outcomes were compared between the normal BMI group and the low group as well as the high BMI group.Risk factors for severe complications after liver resection were analyzed.Results:Among the 484 patients,79(16.3％)were in the low BMI group,328(67.8％)in the normal BMI group,and 77(15.9％)in the high BMI group.The high BMI group had significantly higher ASA score,preoperative albumin level,and proportion of hypertension compared to the normal BMI group(all P＜0.05).Baseline characteristics in the low BMI group showed no significant differences compared to the normal BMI group(all P＞0.05).The incidence rates of overall complications were not significantly among the three groups(P＞0.05).However,the high BMI group had significantly higher incidence rates of severe complications(Clavien-Dindo grade Ⅲ-Ⅳ),postoperative infections,liver failure,and bile leakage compared to the normal BMI group;the low BMI group had significantly higher rates of perioperative blood transfusion,postoperative infections,liver failure,and reoperation compared to the normal BMI group(all P＜0.05).Univariate and multivariate Logistic regression analyses identified high BMI and preoperative total bilirubin ≥54 pmol/L as independent risk factors for severe complications after liver resection in patients with hepatolithiasis(both P＜0.05).Conclusion:Preoperative BMI is closely associated with the occurrence of complications after liver resection in patients with hepatolithiasis,with high BMI being an independent risk factor for severe complications.To mitigate the risk of severe complications,clinical practice should prioritize monitoring and management of individuals with high BMI and other risk factors
