ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction （清肺渗湿汤） combined with western medicine for patients with bronchial asthma of heat wheezing syndrome， and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group， each group with 43 participants. The control group received conventional western medicine， and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group， 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness； secondary outcome measures included traditional Chinese medicine （TCM） syndrome score， asthma control test （ACT） score， pulmonary function indices such as forced expiratory volume in 1 second （FEV₁）， forced vital capacity （FVC）， peak expiratory flow （PEF）， serum inflammatory factor levels including interleukin-4 （IL-4）， tumour necrosis factor-α （TNF-α）， and high-sensitivity C-reactive protein （hs-CRP）， and immune function indices including CD3⁺， CD4⁺， CD8⁺， CD4⁺/CD8⁺. All outcome measures were evaluated before and after treatment. Vital signs were monitored， and electrocardiography， blood routine， urine routine， liver function， and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% （39/40）， which was significantly higher than that of the control group （85.0%， 34/40， P＜0.05）. After treatment， both groups showed decreased TCM syndrome scores， IL-4， TNF-α， hs-CRP， and CD8⁺ levels， as well as increased ACT scores， CD3⁺， CD4⁺， CD4⁺/CD8⁺， FEV₁， FVC， and PEF levels （P＜0.05 or P＜0.01）. Moreover， the improvements in these indices were more significant in the treatment group than in the control group （P＜0.05 or P＜0.01）. No significant abnormalities in safety indicators were observed in either group， and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms， pulmonary function， and clinical effectiveness， with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

This paper summarized Professor ZHOU Zhaoshan's clinical experience in treating bronchial asthma （abbreviated as asthma） by stages with dampness-draining method. It is believed that pathogenic dampness is the key pathological factor in the onset of asthma. Dampness accumulates into water， which gathers into rheum； the condensed rheum forms phlegm， which lingers in the lungs. When external pathogens trigger the latent phlegm， phlegm and qi become mutually obstructed， leading to airway obstruction， disrupted qi movement， and upward reversal of lung qi， thereby resulting in asthma attacks. The treatment emphasizes a stage-based approach. During acute attacks， the main syndromes include cold-damp obstructing the lungs， damp-heat accumulating in the lungs， and shaoyang （少阳） constraint with heat. For the syndrome of cold-damp obstructing the lungs， a self-formulated Wenfei Shenshi Decoction （温肺渗湿汤） is used to warm the lungs and disperse cold， drain dampness and relieve panting； for the syndrome of damp-heat accumulating in the lungs， a self-formulated Qingfei Shenshi Decoction （清肺渗湿汤） is employed to clear the lungs and expel heat， drain dampness and relieve asthma； and for the syndrome of shaoyang constraint with heat， a self-formulated Chaihu Shenshi Decoction （柴胡渗湿汤） is administered to harmonize the shaoyang， clear heat and drain dampness. During the remission stage， treatment is based on the underlying kidney-deficiency constitution， and a self-formulated Bushen Shenshi Decoction （补肾渗湿汤） is formulated to tonify the kidneys and drain dampness， improve qi reception and relieve panting.

BACKGROUND:According to different locations of lumbar disc herniation,it can be classified into many types.Among them,patients with intradural sac type lumbar disc herniation have severe clinical symptoms,which greatly affect their quality of life.Therefore,this article studies the risk factors for its onset,and improving the preoperative diagnostic rate is of great significance for the treatment and prevention of this disease.OBJECTIVE:To explore the risk factors for intradural lumbar disc herniation.METHODS:A retrospective analysis was conducted on 15 patients with intradural lumbar disc herniation(herniation group)admitted to three hospitals in Xuzhou city from May 2014 to November 2022.Propensity score matching was used to match patients with lumbar disc herniation who did not protrude into the dura mater in a ratio of 1:4.A total of 59 patients were selected and included in the non-herniation group.Clinical data were observed in the two groups.Univariate and binary logistic regression analysis,multiple linear regression,and PROBIT regression analysis were utilized to identify the relevant risk factors for intradural lumbar disc herniation.RESULTS AND CONCLUSION:(1)The results of univariate analysis showed that the average disease course,proportion of segments,modified Pfiirmann grading,sacral tilt angle,proportion of previous lumbar spine surgery history,and proportion of heavy manual workers,proportion of lumbar spinal stenosis,redundancy of the cauda equina,and ossification of the posterior longitudinal ligament all showed statistical differences in the herniation and non-herniation groups(P＜0.05).(2)Multivariate regression analysis showed that duration of disease,protruding segment,history of lumbar surgery,modified Pfiirmann grading,cauda equina redundancy,and lumbar spinal stenosis were independent risk factors for intradural lumbar disc herniation.(3)Based on the influencing factors,an receiver operating characteristic curve was constructed,with an area under curve of 0.956(95％CI:0.913-0.998),indicating good discrimination.(4)There was a significant correlation between the duration of the disease,the protruded segment,the history of lumbar spine surgery,the modified Pfirmann classification,cauda equina redundancy,lumbar spinal canal stenosis,and the incidence rate of intradural lumbar disc herniation.

Objective To investigate the efficacy and safety of tirofiban in the treatment of branch atheromatous disease(BAD)in elderly patients.Methods A retrospective analysis was conducted on 215 elderly BAD patients admitted to our department from June 2021 to June 2023.According to their treatment,they were divided into tirofiban group 1(55 cases)and control group 1(160 ca-ses).Using propensity score matching in a ratio of 1∶1 algorithm for adjustment,the differences in baseline features between the two groups were eliminated,and there were finally 53 cases in the tirofiban group 2 and 53 cases in the control group 2 after matching.The NIHSS scores before treatment and at 24 h and 7 d after treatment were collected.All of them were followed up for 90 d,and modified Rankin scale(mRS)was applied to evaluate the prognosis.Results The tirofiban group 1 had significantly lower NIHSS score at 24 h and 7 d after treatment and shorter length of hospital stay than the control group 1(P＜0.05,P＜0.01),so were in the tirofiban group 2 than the control group[3(1,4)vs 3(2,6),1(0,3)vs 1(1,4),8(6,10)d vs 9(8,11)d,P＜0.05].The proportion of mRS score ≤1 was obviously larger in the tirofiban group 1 than the control group 1(P＜0.01).The tirofiban group 2 obtained notably larger proportions of mRS score≤1 and≤2(71.7％vs 43.4％,P=0.003;79.2％vs 60.4％,P=0.034),and smaller proportion of mRS≥4(5.7％vs 20.8％,P=0.045)when compared with the control group 2.Logistic regression analysis indicated that in the patients without diabetes and those non-smoking,tirofiban was associated with increased good outcomes(OR=0.266,95％CI:0.090-0.788,P=0.017;OR=0.341,95％CI:0.107-0.931,P=0.046).Conclusion Tirofiban may effectively improve the clinical outcomes in the elderly BAD patients.But further randomized controlled trials are needed for verification.

Objective:To explore genomic features associated with gemcitabine sensitivity, patient-derived organoid models of biliary tract cancer (BTC) were established and characterized.Methods:This is an experimental study. The tissue specimens of BTC were collected from patients who underwent surgical resection at the Department of Hepatobiliary and Pancreatic Surgery,the Second Affiliated Hospital of Zhejiang University School of Medicine between January 2020 and December 2023. The tumor organoids were cultured in vitro and histologically characterized. Drug sensitivity testing was performed using gemcitabine,cisplatin,paclitaxel,fluorouracil,and lenvatinib etc. to evaluate cell viability. The correlation between the drug sensitivity of organoids and clinical therapeutic response was analyzed.Results:Thirty-eight patient-derived organoids (PDO) models were successfully established from 43 biliary tract malignancy patients with complete follow-up data,including gallbladder cancer PDO 14 cases,distal bile duct cancer PDO 16 cases,intrahepatic cholangiocarcinoma PDO 8 cases,achieving an overall success rate of 88.4%. Drug sensitivity testing (DST) was performed on the successfully generated PDO,with 35 models successfully completing DST experiments. The overall consistency rate between drug responses in PDOs and clinical survival outcomes in corresponding patients was 8/14. Transcriptomic analysis of gemcitabine-sensitive vs. gemcitabine-resistant PDO identified 71 differentially expressed genes in the resistant group,the significantly up-regulated genes including GLDC, LINC01595, IL-27, ANGPTL3, CYP7A1,and AKR1C1;the significantly down-regulated genes including P2RY2,LIPC,and ECHDC3. Conclusion:A biobank of patient-derived organoids of BTC has been established,which demonstrates its potential as preclinical models and tools for predicting chemotherapy responses for BTC patients.

BACKGROUND:Cross-sectional area and fat infiltration are the standard parameters for quantifying paravertebral muscle,but it is too cumbersome and time-consuming to introduce new quantifying indicators. OBJECTIVE:To investigate the relationship between paravertebral muscle and spinopelvic sagittal parameters and the predictive value of lumbar indentation value for sagittal balance in patients with isthmic spondylolisthesis.METHODS:The study included 87 patients diagnosed with spondylolisthesis,all of whom had grade Ⅱ spondylolisthesis according to Meyerding classification,including 40 males and 47 females,with a mean age of (51.4±9.1) years. The sagittal vertical axis,pelvic incidence angle,pelvic inclination angle,sacral inclination angle,lumbar lordosis,thoracic kyphosis,and the difference between pelvic incidence and lumbar lordosis were measured. The total cross-sectional area,functional cross-sectional area,and fat infiltration of lumbar paracolateral muscles were measured. Pearson correlation analysis was used to investigate the correlation between sagittal parameters and paravertebral muscle measurements. Multiple linear regression was used to analyze the effects of lumbar indentation value,age,sex,and body mass index on spinopelvic sagittal balance. The receiver operating characteristic curve was used to find the best cut-off point of the indentation value of the lumbar spine,and the relationship of sagittal vertical axis and pelvic incidence with lumbar lordosis was evaluated.RESULTS AND CONCLUSION:(1) According to Pearson correlation analysis,the total cross-sectional area of the multifidus muscle was significantly correlated with lumbar lordosis (r=0.464,P<0.01) and the difference between pelvic incidence and lumbar lordosis (r=-0.306,P<0.01). The functional cross-sectional area of multifidus muscle was significantly correlated with lumbar lordosis (r=0.367,P<0.01) and the difference between pelvic incidence and lumbar lordosis (r=-0.228,P<0.05). The indentation value of lumbar spine was significantly correlated with the sagittal vertical axis (r=-0.300,P<0.01),lumbar lordosis(P=0.417,P<0.01),thoracic kyphosis (r=0.351,P<0.01),and the difference between pelvic incidence and lumbar lordosis (r=-0.319,P<0.01). (2) According to multiple linear regression analysis,the indentation value of lumbar spine was independently correlated with the difference between pelvic incidence and lumbar lordosis and the sagittal vertical axis. 55％ (11/20) of patients with lumbar indentation value ≤11.5 mm had sagittal vertical axis ≤ 50 mm,while 96％(64/67) of patients with lumbar indentation value>11.5 mm had sagittal vertical axis ≤ 50 mm. 30％ (6/20) of patients with the difference between pelvic incidence and lumbar lordosis ≤ 11.5 mm had the difference between pelvic incidence and lumbar lordosis ≤ 10°,while 66％ (44/67) of patients with lumbar indentation value>11.5 mm had the difference between pelvic incidence and lumbar lordosis ≤ 10°. (3) It is concluded that both total cross-sectional area and functional cross-sectional area were significantly correlated with lumbar lordosis and the difference between pelvic incidence and lumbar lordosis. Lumbar indentation value,as a new indicator for the evaluation of paravertebral degeneration,was independently correlated with the sagittal vertical axis and the difference between pelvic incidence and lumbar lordosis,and had certain predictive value for postoperative sagittal plane correction. It was a simple and practical method for the evaluation of spinopelvic sagittal plane and paravertebral muscle degeneration. The degeneration of the paravertebral muscle is related to spinopelvic sagittal balance.
