ObjectiveTo observe the clinical efficacy and safety of Yuyin Lidan granules （YYLD） in preventing the recurrence of common bile duct stones （CBDS） in patients with liver and gallbladder dampness-heat syndrome following endoscopic retrograde cholangiopancreatography （ERCP）. MethodsThis randomized， parallel， controlled trial enrolled postoperative CBDS-ERCP patients who met the inclusion and exclusion criteria. Sixty-four patients were randomly assigned to an observation group or a control group， with 32 cases in each. Both groups received conventional Western medical treatment after ERCP， while the observation group additionally received YYLD for 8 weeks. The follow-up period lasted for 1 year. The efficacy indicators included bile bilirubin levels， traditional Chinese medicine （TCM） syndrome scores， clinical efficacy rate， pancreatitis and inflammation markers， postoperative liver function， and CBDS recurrence rate at 1-year follow-up， which were used to jointly evaluate the clinical efficacy and safety of both groups. ResultsA total of 56 patients completed the study and were included in the final analysis， i.e.， 29 in the observation group and 27 in the control group. Baseline characteristics were comparable between the two groups. Compared with pre-treatment and with the control group after treatment， the bile bilirubin level in the observation group significantly decreased （P<0.05）. After treatment， the clinical cure and marked improvement rates were higher in the observation group than in the control group， showing a statistically significant difference in overall clinical efficacy （P<0.05）. Compared with pre-treatment， the primary and secondary symptoms in the observation group， as well as the primary symptom and the secondary symptom of nausea and vomiting in the control group （weeks 4 and 8）， were significantly reduced （P<0.05）. Compared with the control group after treatment， the observation group showed significant reductions in the primary symptom of loose stools/constipation （day 5 and week 4） and in three secondary symptoms， i.e.， bitter taste and sticky dry mouth， abdominal distension and poor appetite （throughout the treatment period）， and general heaviness and fatigue （day 5 and week 4）， with statistical differences （P<0.05）. Compared with pre-treatment， both groups showed decreased lipase and urinary amylase levels （P<0.05）. However， no significant between-group differences were observed in pancreatitis or inflammation-related indices after treatment. Compared with pre-treatment， all liver function indicators in the observation group and alanine aminotransferase （ ALT ）， γ-glutamyl transferase （ γ-GT ）， alkaline phosphatase （ALP）， and conjugated bilirubin in the control group significantly decreased at weeks 4 and 8 （P<0.05）. Compared with the control group after treatment， only serum total bilirubin and unconjugated bilirubin were significantly reduced in the observation group during the treatment period （P<0.05）. ConclusionYYLD combined with conventional Western medical treatment can effectively regulate bilirubin metabolism （in bile and serum）， improve TCM clinical symptoms， and prevent CBDS recurrence after ERCP in patients with liver and gallbladder dampness-heat syndrome. This regimen is safe and effective and is worthy of further clinical research and promotion.

Objective To analyze the differences in bone serum protein between patients with osteoporosis accompanied by obstructive sleep apnea syndrome(OSAS)and those with osteoporosis only using proteomics.Methods A total of 80 osteoporosis patients who attended our hospital between June 2022 and June 2024 were enrolled.Based on their polysomnography results,the participants were divided into an OSAS and osteoporosis comorbidity(OSAS-osteoporosis)group(n=42)and an osteoporosis only group(n=38).Propensity score matching was applied to incorporate covariates in logistic regression so that the individual characteristics of the two groups of patients were generally balanced.Following the matching procedure,a final cohort of 20 matched pairs was obtained and subsequently utilized for further analysis.The mass spectrum was obtained using laser desorption ionization mass spectrometry.Principal component analysis(PCA)was performed to assess differences in metabolic patterns between groups.Partial least squares discriminant analysis(PLS-DA)and orthogonal PLS-DA(OPLS-DA)were employed for further data analysis.Variable importance in projection(VIP)scores of each substance were calculated with OPLS-DA to screen the metabolites showing inter-group differences.Heatmaps were generated to visualize metabolic profile differences between the OSAS-osteoporosis group and the osteoporosis group.Enrichment pathway analysis was conducted on the differential identified metabolites.Results After propensity score matching,individual characteristics between the groups were well balanced.Mass spectrometry revealed significant differences between the OSAS-osteoporosis and osteoporosis groups.In the PCA score plot,the separation trend of the two groups was not significant.The PLS-DA score plot showed a discernible separation trend,with R2 and Q2 lower than those of the corresponding results of the real model,confirming the reliability of the model.OPLS-DA showed that the total R2X of the model was 0.635,R2Y was 0.879,and O2Y was 0.728,showing obvious separation trends between the two groups.A total of 16 differential metabolites were identified,including stearyl-oleyl-glycerol phosphate choline,phosphate choline,L-histidine,erucamide,2'-deoxyuridine,1-palmitoyl glycerol,thymine,tyramine,L-pyroglutamic acid,L-glutamic acid,myristate,glycerol-3-phosphate,caprylic acid,pregnenolone,L-arginine,D-4-hydroxyphenylglycine,and isobutyric acid.Heatmaps showed significant differences in metabolic profiles between the OSAS-osteoporosis group and the osteoporosis group.Pathway enrichment analysis showed that 27 metabolic pathways were involved.27 metabolic pathways.Under the conditions of P<0.05 and pathway impact>0.2,the three most significant metabolic pathways identified included mainly alanine,aspartate,and glutamate metabolism,arginine biosynthesis,and histidine metabolism.Conclusion Significant differences were observed in the metabolic profiles between patients with both OSAS and osteoporosis and those with osteoporosis alone.

Objective:To explore the relationship between risk perception and health promoting lifestyle profile in population with cardiovascular disease (CVD), and construct a prediction model for clinical screening and targeted intervention.Methods:A cross-sectional survey method was used to select 272 people at moderate and high risk of CVD from the Second Affiliated Hospital of Zhejiang University School of Medicine from March to August 2022. The general information questionnaire, Chinese version of Attitude and Beliefs about Cardiovascular Disease Knowledge and Risk Questionnaire (ABCD-C), and Health Promoting Lifestyle Profile-II (HPLP Ⅱ) were used. Based on multiple regression analysis, a nomogram model for health promoting lifestyle in high-risk CVD population was constructed.Results:Among 272 participants, male 150 cases, female 122 cases, aged (60.58 ± 10.64) years old. The total ABCD-C score was (56.57 ± 5.69), and the total HPLP Ⅱ score was (111.92 ± 12.47). ABCD-C score was significantly positively correlated with HPLP Ⅱ score ( r=0.556, P<0.01). The median of HPLP Ⅱ total score (111 points) was used as the cut-off point for low level of health-promoting lifestyle (≤111 points) and high level of health-promoting lifestyle (>111 points), and used it as the dependent variable, smoking ( OR=0.215, 95% CI 0.104-0.446) was a barrier factor for participants to adopt healthy lifestyle; being married ( OR=14.237, 95% CI 1.963-103.238), having a family average monthly income higher than 5 000 yuan ( OR=4.101, 95% CI 1.369-12.288), higher score of CVD prevention knowledge ( OR=1.660, 95% CI 1.373-2.007), perceived benefits and intention to change physical activity ( OR=1.445, 95% CI 1.255-1.663), perceived benefits and intention to change healthy diet ( OR=1.322, 95% CI 1.058-1.654) were promoting factors. Conclusions:The health-promoting lifestyle of populations at risk for CVD is above-average, influenced by factors such as smoking, marital and economic status, risk attitudes, and beliefs. Utilizing the nomogram model for early screening and targeted risk communication among key populations may contribute to improving their health behavior.

Objectives:This study aims to investigate the impact of different Low-Density Lipoprotein cholesterol(LDL-C)levels on progression of intermediate coronary stenosis,and the associated risk factors leading to the progression of such lesions. Methods:Data were collected on 219 consecutive patients admitted at the Fuwai Central China Vascular Hospital from January 2020 to February 2021,underwent angiographic examinations and diagnosed with intermediate coronary stenosis,with at least one follow-up angiography after 11 months.Offline quantitative flow ratio(QFR)analysis was performed on these cases.Patients were divided into two groups:LDL-C controlled group(LDL-C<1.8 mmol/L,148 patients with 191 vessels)and LDL-C uncontrolled group(LDL-C≥1.8 mmol/L,71 patients with 98 vessels).Coronary artery QFR and anatomical indicators such as minimal lumen diameter,minimal lumen area,percentage diameter stenosis,percentage area stenosis were compared within and between the groups.Further analysis was performed to identify influencing factors leading to changes in coronary physiological parameters derived from QFR. Results:Within the LDL-C controlled group,there was no significant difference in the QFR values of the vessels compared to baseline(P>0.05),whereas in the LDL-C uncontrolled group(P<0.05),a notable decline in QFR was observed.Patients in the LDL-C controlled group had lower rates of maximum diameter and area stenosis and higher minimum lumen diameter and area(all P<0.05).Through multifactorial Logistic regression analysis,it was found that a body mass index＞28 kg/m2,LDL-C≥1.8 mmol/L,and a history of myocardial infarction were independent risk factors leading to the decline in QFR(all P<0.05). Conclusions:It was found that patients in the LDL-C controlled group had higher coronary artery QFR,minimum lumen diameter and area,lower rates of maximum diameter and area stenosis.

Objective:To investigate the influence of varied oxygen (O 2) concentration environments on the phenotypic transformation of pulmonary artery smooth muscle cells (PASMC) and the mechanism of pulmonary hypertension. Methods:Primary rat PASMC were isolated and cultured through the process of enzymatic digestion. Following identification, the stable passaged PASMC were subjected to a 6-hour incubation in sealed containers with normal O 2 content (group C) and relative O 2 content comprising 55% (group H55), 75% (group H75), and 95% (group H95). mRNA and protein expression of α-Actin (α-SMA), smooth muscle 22α (SM22α), osteopontin (OPN), and matrix metalloproteinase-2 (MMP-2) were measured using real-time quantitative PCR and western blot analysis. Results:The H55 group displayed no significant difference from the C group in terms of mRNA and relative protein expression levels for α-SMA, SM22α, OPN, and MMP-2 (all P>0.05). On the other hand, groups H75 and H95 exhibited a reduction in mRNA and relative protein expression of α-SMA and SM22α, along with an increase in mRNA and relative protein expression of OPN and MMP-2 when compared with both the C and H55 groups (all P<0.05). The H95 group showed a higher relative mRNA expression of MMP-2 as compared to the H75 group ( P<0.05). Conclusions:Oxygen concentration environments of 75% or higher can serve as the foundation for the pathogenesis of pulmonary hypertension, essentially by inducing a phenotypic transformation in PASMC towards adopting a robust secretory function. This induction is contingent upon the concentration of oxygen present.

Objective To construct a predictive model of thrombus clearance rate to guide the selection of therapeutic strategies for acute lower extremity venous thromboembolism patients by studying the clinic data of patients who underwent AngioJet mechanical thromboaspiration surgery.Methods By calculating the thrombus clearance rate in 83 VTE patients treated with AngioJet surgery,correlation analysis of clinical data,combined with the characteristic factors in the LASSO regression model,multiple logistic regression analysis was applied to build a prediction model of thrombus clearance rate column line graph,and the accuracy of the prediction model was evaluated using C index,calibration curve and decision curve.Results VTE type was significantly correlated with thrombus clearance rate,and the predictors in the column line plot contained:age,sex,thrombus type,surgical history,tumor history,and smoking history.The model showed great predictive power and high accuracy with a C-index of 0.795(95％CI:0.682 3-0.905 7).Decision curve analysis showed that prediction of thrombus clearance by column line plot for AngioJet procedure was effective when the threshold probability was in the range of 0.02-0.63.Conclusion In the correlation analysis,VTE type was significantly correlated with thrombus clearance.The results of this study showed that the AngioJet thrombus aspiration procedure was able to achieve a high rate of thrombus clearance in men older than 65 years with a history of tumors,a central thrombus type,no history of surgery,and no history of smoking.

Objective To explore the optimal ratio of Baitong decoction based on efficacy,clarify its spectrum-effect relationship,and identify its potential quality markers.Methods An ulcerative colitis(UC)model in mice was established using dextran sulfate sodium.The efficacy of Baitong decoction with varying drug ratios was assessed by evaluating the apparent score,pathological score and inflammatory factor changes of UC in each group of experimental animals.The fingerprints of Baitong decoction with different ratios were established by high performance liquid chromatography(HPLC),and the relationship between the content of each substance and its efficacy was analyzed by partial least squares regression to determine the potential quality markers of Baitong decoction.Results Baitong decoction was most effective in relieving ulcerative colitis when the mass ratio of Fuzi,Ganjiang and Congbai was 1∶2∶2.The fingerprinting identified 14 common peaks across 7 ratios,with 9 peaks were found to be associated with the remission of ulcerative colitis by partial least squares regression analysis.Conclusion The optimal ratio of Fuzi,Ganjiang and Congbai for treating UC is 1∶2∶2.The spectrum-effect relationship analysis suggested that the quality markers of Baitong decoction may be the substances represented by peak 2(benzoylaconine),3,5,6,8(mesaconine),9(aconitine),10(hypaconitine),13(10-gingerol)and 14.

Objective:To evaluate the preventive effect of indwelling pancreatic duct guide wire through nasobiliary drainage catheter for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in cholelithiasis patients with small-caliber pancreatic duct.Methods:The clinical data of 127 patients with gall bladder and common bile duct stones undergoing ERCP and elective laparoscopic cholecystectomy in the Cholelithiasis Center of Shanghai East Hospital Affiliated to Tongji University from January 2019 to June 2023 were analyzed retrospectively, including 55 males and 72 females, aged (56.95±10.86) years old. According to the preventive methods of PEP, patients were divided into the guide wire group (indwelling pancreatic duct guide wire through nasobiliary drainage catheter), stenting group (nasobiliary catheter with 5Fr 5 cm single pigtail pancreatic duct stent) and conventional group (nasobiliary catheter). The incidence of post-ERCP hyperamylasemia (PEH) and PEP were compared.Results:The incidence of PEH in the guide wire group was lower than that in the conventional group [17.8% (8/45) vs. 43.5% (10/23), P=0.023], and also lower than that in the stenting group [17.8% (8/45) vs. 32.2% (19/59)], despite no statistical significance ( P=0.337). The incidences of PEH were comparable in the stenting group and conventional group [32.2% (19/59) vs. 43.5% (10/23), P=0.096)]. The incidence of PEP in the guide wire group was lower than that in both the stenting group [6.7% (3/45) vs. 23.7% (14/59), P=0.030]. and conventional group [6.7% (3/45) vs. 30.4% (7/23), P=0.025]. The incidences of PEP were comparable in the stenting and conventional group [23.7% (14/59) vs. 30.4% (7/23), P=0.532]. Conclusion:Compared to the preventive pancreatic duct stenting, indwelling pancreatic duct guide wire through nasobiliary drainage catheter can effectively prevent the PEH and PEP in high-risk patients with a small-caliber pancreatic duct.

Objective:To evaluate the data quality of Shenzhen Type 1 Diabetes Alliance (SZT1D), and to provide a basis for evaluation and improvement for the continuous improvement of data quality.Methods:From December 2018 to July 2021, 697 first-visit type 1 diabetes (T1DM) patients (including 501 in Shenzhen and 196 out-of-Shenzhen) and 120 re-visited T1DM patients (including 113 in Shenzhen and 7 out-of-Shenzhen) who were registered by SZT1D in collaborative research platform network of China Type 1 Diabetes Alliance (hereinafter referred to as China T1D). The data quality was evaluated from three dimensions: data completion, accuracy and revisit. The data completion degree was evaluated by the overall data completion degree and the key indicator completion degree; the data accuracy was evaluated by the probability of abnormal blood glucose value; the patient′s return visit was evaluated by the return visit rate.Results:The main characteristics of T1DM in SZT1D were young and middle-aged adults [age: (34.4±17.1)years] with thin body [BMI: (19.80±3.52)kg/m 2)], half of male and female patients [proportion of male: 52.4%(365/697)]; the main types of diagnosis were classical T1DM [65.22%(150/230)] and latent autoimmune diabetes in adults(LADA) [26.08%(60/230)], and the fasting blood glucose (FPG) [(10.93±6.98)mmol/L] and glycosylated hemoglobin (HbA 1c) [(10.63±3.01)%] were high. The average completion rate of the overall data of the first diagnosed patients in SZT1D was only 60% [(62.9±31.5)%]: the number of patients with overall data completion ≥80% in SZT1D was only 50.2%(350/697); the number of patients with overall data completion ≥80% in Shenzhen was less than that outside Shenzhen [44.3%(222/501) vs 65.3%(128/196), P<0.001]. The key indicators with better completion rate of first-visit were disease course [76.2%(531/697)], age of onset [75.8%(528/697)], family history of diabetes [74.9%(522/697)], etc., but none of them had a completion rate of more than 80%, and the diabetes self-management behavior assessment questionnaire and scale score were completely missing; the frequency of daily blood glucose monitoring [46.1%(231/501) vs 64.3%(126/196), P<0.001], current insulin regimen [44.3%(222/501) vs 63.3%(124/196), P<0.001], number of diabetic ketoacidosis (DKA) since the onset of the disease [45.7%(229/501) vs 64.8%(127/196), P<0.001] and the number of symptomatic hypoglycemia in the past 1 month [39.3%(197/501) vs 63.8%(125/196), P<0.001] were higher in Shenzhen than those reported outside Shenzhen. In addition, the probability of abnormal FPG and postprandial glucose (PPG) [5.2%(24/466); 3.8%(19/236)] were low. The revisit rate was not high [17.2%(120/697)], and the revisit rate in Shenzhen was higher than that outside Shenzhen [22.6%(113/501) vs 3.6%(7/196), P<0.001]. The first revisit rate was 16.2%(113/697) and the second revisit rate was seriously insufficient [1.0%(7/697)]. Conclusions:The data quality of T1DM patients recorded by SZT1D needs to be further improved. Improving the information interconnection between China-T1D and SZT1D, employing quality control personnel and building a systematic data quality evaluation analysis and feedback mechanism are methods to promote the comprehensive, accurate and efficient input of T1DM data and continuously improve the evaluation methods to improve the overall data quality.

Objective:To study the feasibility and safety of percutaneous jejunal drainage in treatment of hepatolithiasis after choledochojejunostomy.Methods:The clinical data of 24 patients with hepatolithiasis after choledochojejunostomy treated by percutaneous jejunal drainage at the Cholelithiasis Center, Shanghai East Hospital Affiliated to Tongji University from May 2021 to May 2022 were retrospectively analyzed. There were 16 males and 8 females, aged (50.46±10.89) years old. Ultrasound and X ray guided percutaneous jejunography was performed under local anesthesia for patients with hepatolithiasis after choledochojejunostomy. Then the fistula was directly dilated to 16.0Fr, and percutaneous jejunal choledochoscopy was performed 3 days later. The success rate, complication rate and stone removal rate were analysed.Results:Twenty-four patients were treated with percutaneous jejunography, with a success rate of 79.2%(19/24), including 19 patients after anterior colonic cholangiojejunostomy with a success rate of 94.7%(18/19), and 5 patients after retrocolonic cholangiojejunostomy with a success rate of 20.0%(1/5). There was no complication including bleeding, intestinal leakage and bile leakage. In 19 patients with successful percutaneous jejunography, the success rate of fistula dilation was 100%(19/19), and there was no complication. Five patients with failed percutaneous jejunography underwent open choledocholithotomy through the jejunal output-loop, and bile leakage occurred in one patient. Thirteen patients with anastomotic stenosis, 5 with intrahepatic biliary strictures, and 6 with anastomotic and intrahepatic biliary strictures were diagnosed by choledochoscopy and selective cholangiography in these 24 patients. After choledochoscopic electrotomy, cylindrical balloon dilation, stone removal, stenting and other treatments, the stenosis relief rate was 100%(24/24), and the clearance rate of intrahepatic bile duct stones was 91.7%(22/24).Conclusion:Percutaneous jejunal drainage was a feasible, safe and minimally invasive method for treatment of hepatolithiasis after choledochojejunostomy. The procedure was especially suitable for patients with anterior colonic cholangiojejunostomy.
