Objective To explore clinical methods for preventing the recurrence of biliary pancreatitis.Methods Clinical data of 112 consecutive cases of acute biliary pancreatitis from January 1999 to July 2001 treated in this hospital were analyzed retrospectively.Before admission all the patients had no history of biliary pancreatitis or cholecystectomy.According to whether or not an endoscopic sphincterotomy(EST) or cholecystectomy was given,the patients were divided into 4 groups: Conservative Group(n=45),EST Group(n=22),Cholecystectomy Group(n=29),and Combination Group(n=16).The recurrence rates of pancreatitis of the 4 groups were compared each other.Results The 112 patients were followed for 16~30 months(mean,18.5 months).Recurrence of pancreatitis was found in 12 patients in the Conservative Group(26.7%,12/45) and in 2 patients in the Cholecystectomy Group(6.9%,2/29).No recurrence was seen in the EST Group and the Combination Group.As compared with the Conservative Group,both EST and cholecystectomy significantly decreased the recurrence rate of biliary pancreatitis.The 2 recurrent patients in the Cholecystectomy Group were given an endoscopic retrograde cholangiopancreatography(ERCP),by which small common bile duct calculi were found.Conclusions Common bile duct calculus is the major cause of recurrence of biliary pancreatitis.Both EST and cholecystectomy can decrease the recurrence rate of biliary pancreatitis.EST is suitable for elderly high-risk patients because of its minimal invasion.

Objective [WT5”BZ] To evaluate the role of duodenoendoscopy in the diagnosis and treatment of acute pancreatitis with gallstone (AP).[WT5”HZ] Methods [WT5”BZ] 45 AP cases were randomized into group of endoscopic retrograde cholangiopancreatography (ERCP) (n=20) and non ERCP group (n=25). All patients were further stratified into mild and severe subgroups according to APACHE Ⅱ scores. All cases were given supportive treatment combined with traditional Chinese medicine. The patients in ERCP group received ERCP within 24 hours of admission. If stones were found, endoscopic sphincterotomy (ES) was performed to extract the stones by basket. In cases with multiple stones or if no stone could be immediatly identifiable, endoscopic naso billiary drainage (ENBD) was applied.[WT5”HZ] Results [WT5”BZ]In patients with severe AP, the morbidity, length of hospital stay and cost were significantly lower in ERCP treatment subgroup than those without ERCP treatment (all P

Objective To investigate current situations,influencing factors and related strategies in insufficient bowel preparation for colorectal endoscopy in diabetic patients.Methods A total of 325 diabetic patients who were going to undergo colorectal endoscopy in our hospital were included as the research subjects from January 2021 to December 2022.The demographic,sociological and clinical data of the patients were collected to review and analyse the current situation of inadequate bowel preparation for colorectal endoscopy by convenience sampling method.The influencing factors of inadequate bowel preparation were analysed so as to provide references for formulating relevant interventional strategies for bowel preparation.Results The rate of inadequate bowel preparation in the 325 diabetic patients was found at 25.85%(84/325).The risk factors of insufficient bowel preparation included male(OR=2.157),age(OR=1.212),poor education(OR=2.811),constipation(OR=2.469),outpatients(OR=2.213),low score in activity of daily living(ADL,OR=0.858)and lower score in walking function(OR=0.701)(P<0.05 for all the factor).Conclusions The insufficient bowel preparation in patients with diabetes is at a higher level.The influencing factors of the insufficient bowel preparation include male,age,poor education,constipation,outpatients,lower score in activity of daily living and lower score in walking function.Medical staff should take measures corresponding to the influencing factors in order to reduce the influence upon an insufficient bowel preparation and ensure a smooth colonoscopy.

Objective: To investigate the short-term efficacy and toxicity of bevacizumab combined with DP or rh-endostatin（recombinant human vascular endostatin injection）combined with DP in locally advanced EGFR wild-type non-small cell lung cancer (NSCLC). Methods: Seventy-two patients with treatment of locally advanced EGFR wild-type NSCLC admitted to the Department of Respiratory Medicine of Zhongshan Hospital Affiliated to Guangdong Medical University from January 2014 to January 2017 were divided into bevacizumab group (34 cases) and rh-endostatin group (38 cases) according to the random number method. The former group was treated with bevacizumab combined with docetaxel and cisplatin, while the latter was treated with rh-endostatin combined with docetaxel and cisplatin. According to RECISIT 1.1 standard, the changes of lesion size before and after treatment in two groups were evaluated. Serum levels of vascular endothelial growth factor (VEGF), carcinoembryonic antigen (CEA), cytokeratin 21-1 fragment (CYFRA21-1), squamous cell carcinoma antigen (SCC) were measured. The adverse reactions during treatment were also evaluated. Results: In bevacizumab group, patients with CR, PR, SD, PD, DCR and ORR were 2 cases, 12 cases, 15 cases, 5 cases, 41.18% and 85.29%, respectively. In rh-endostatin group, patients with CR, PR, SD, PD, DCR, ORR were 2 cases, 16 cases, 14 cases, 6 cases, 47.37% and 84.21%, respectively. The DCR in rh-endostatin group was significantly higher than that in bevacizumab group (P<0.05).The serum levels of VEGF and CEAin rh-endostatin group decreased more obvious than those in bevacizumab group (all P<0.05). The incidence of gastrointestinal reaction, skin reaction and cardiac toxicity in rh-endostatin group was higher than that in bevacizumab group, while the incidence of bleeding in bevacizumab group was higher than that in rh-endostatin group (all P<0.05). Conclusion: In patients with locally advanced EGFR wild-type NSCLC, rh-endostatin combined with DP regimen is better than bevacizumab combined with DPregimen. In clinical practice, corresponding treatment regimen can be selected according to different characteristics of patients, so as to minimize the toxic reaction during treatment and avoid clinical risk.

Objective:To investigate the changes of various cytokines and coagulation function in B cell acute lymphoblastic leukemia(ALL) patients with different CRS scores during CD19-CAR-T cell immunotherapy.Methods:87 patients with B-ALL hospitalized in the First Affiliated Hospital of Soochow University and 30 normal controls were enrolled into this study from July 2018 to October 2020. The age of the patients was 32(20, 56) years old and 36(41.4%) were female. All these coagulation indicators, prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, fibrinogen (Fg) were analyzed by automatic blood coagulation in B-ALL patients before and after treated with CAR-T cell. The ratio of CD19-CAR-T cells and the expression of IL-6, IL-10, IFN-γ, TFN-α, IL-2, IL-4, and IL-17A were analyzed using flow cytometry. The patients′ clinical parameters were detected, and the CRS classification of severity was made according to the standard of consensus.Results:Patients with CRS>3 had prolonged PT and APTT, increased D-dimer, and decreased fibrinogen ( P<0.05). The levels of cytokines of IFN-γ, IL-6, and IL-10 were significantly higher in patients with CRS>3 than that in controls ( P<0.05).The D-dimer level is positively correlated with IL-10. Conclusion:Patients with severe CRS grading have significant coagulation dysfunction in CD19-CAR-T cell immunotherapy. Cytokines IFN-γ, IL-6, and IL-10 may affect coagulation function and CRS grading during CD19-CAR-T cell immunotherapy.

Objective To explore the relationship between iodine and fluoride content in drinking water and the incidence of adult thyroid nodules in Cangzhou,Hebei.Methods According to the previous reports on iodine and fluoride levels in drinking water in Cangzhou,from November 2016 to January 2017,Cangzhou was divided into high iodine,low iodine,normal iodine and fluorine,low iodine and high fluorine,high iodine and high fluorine areas,and according to the different contents of iodine and fluorine in drinking water,high iodine and high fluorine area was further divided into high iodine and high fluorine 1 (iodine:743.30 μg/L,fluorine:4.27 mg/L),2 (iodine:119.31μg/L,fluorine:4.67 mg/L) and 3 (iodine:105.30 μg/L,fluorine:1.64 mg/L) subareas.Subjects who lived for 20 or more years and aged 30 or older,without serious disease and not taken iodized salt were selected.Palpation was used to examine the size,texture,mass,tenderness and mobility of the thyroid gland.The boundary,internal echo,blood flow and quantity of nodules were observed and recorded by color Doppler.Results The prevalence difference of thyroid nodules [36.8％ (629/1 710),32.8％ (636/1 938),25.1％ (427/1 700)] in high iodine,low iodine and normal iodine and fluorine areas was statistically significant (x2 =55.597,P ＜ 0.05).The prevalences of thyroid nodules in both high iodine and low iodine areas were higher than that of normal iodine and fluorine area (P＜ 0.016 7).The prevalence difference of thyroid nodules [43.3％ (749/1 730),39.8％ (712/1 790),34.9％ (623/1 785)] in high iodine and high fluorine 1,2 and 3 subareas was statistically significant(x2 =26.220,P ＜ 0.05).Compared with low iodine area,the prevalence of thyroid nodules [41.2％ (735/1 785)] in low iodine and high fluorine area was increased (x2 =6.288,P ＜ 0.05).Conclusions Both high iodine and low iodine can induce thyroid nodules.In water source areas with high iodine content,both high iodine and high fluorine are the factors inducing thyroid nodules.The prevalence of thyroid nodules in low iodine and high fluorine area is significantly higher than that of low iodine area.
