Objective To investigate the clinical effect of non-steroidal anti-inflammatory drugs and αl-adrenergic antagonist on treating patients with ureteral stones.Methods A total of 128 patients with ureteral colic due to ureteral stones were randomly divided into control and treatment group,and 64 cases in each group.Both two groups were treated with tamsulosin 0.4 mg oral,intravenous injection of saline 1000 mL Patients in treatment group were received intramuscular non-steroidal anti-inflammatory drugs(10 mg) and patients in control group were received pethidine hydrochloride(10 mg).Ultrasound exam were performed after 6-8 h to evaluate the stone expulsive rate.Extracorporeal shock wave lithotripsy and other treatment were underwent when the stone was still not discharge.Results The effective rate of analgesia was 96.9％ (62/64) in treatment group and 100％ (64/64) in control group(x2 =2.03,P =0.50).The stone expulsion rate in treatment group was 28.1％ (18/64),higher than that in control group(12.5％ (8/64),x2 =4.83,P =0.05).Conclusion It is effective to relive ureteral cohc with non-steroidal anti-inflammatory drugs only,and it is better than pethidine in promote stone expulsion when they both used with α1-adrenergic antagonist.

Objective To observe the expression and significance of hypoxia inducible factor (HIF)-1α,matrix metalloproteinase(MMP)-9 and transforming growth factor(TGF)-β1 in liver tissues of rats with hepatic fibrosis and the effects of TGF-β1 vaccine on the expressions of HIF-1α,MMP-9 and TGF-β1.Methods The hepatic fibrosis rat model was set up by dimethylnitrosamine (DMN).The rat model was injected with TGF-β1 vaccine.The expressions of HIF-1α,MMP-9 and TGF-β1 were detected by immunohistochemistry in rat fibrosis tissues after 6 weeks.Results The expressions of HIF-1α,MMP-9 and TGF-β1 in fibrosis model group and TGF-β1 vaccine group were all significantly higher than control group(P＜0.01),which was positively correlated with the fibrosis degree(r=0.911,0.814 and 0.836,respectively,P＜0.01).However,the expressions of HIF-1α,MMP-9 and TGF-β1 in TGF-β1 vaccine group were all significantly decreased than fibrosis model group (t=2.62,4.03,3.43;P＜0.01).Conclusion During the development of liver fibrosis,HIF-1α promotes the transcriptions and expressions of MMP-9 and TGF-β1.

Objective To investigate the therapeutic effects and mechanisms of interleukin-10 (IL-10) gene-modified dendritic cells (DC-IL-10) in mice with liver fibrosis. Methods DC-IL-10 was constructed in vitro, the phenotype and function of which were evaluated by flow cytometry. BALB/c mice were treated with intraperitoneal injection of carbon tetrachloride(CCl4)to establish liver fibrotic model. DC-IL-10 was administrated via tail vein. Animals were divided into 4 groups including normal dendritic cell (DC) control , liver fibrosis only, negative lentiviral transfection DC (DC-mock) and DC-IL-10. Liver function, cytokine secretion, T lymphocyte differentiation and liver histomorphology were tested. Real-time PCR and western blot were used to analyze the effect of DC-IL-10 on Wnt/β-catenin signaling pathway and its role in liver fibrosis. Results When compared with DC control and DC-mock, the expression of DC-IL-10 surface stimulating molecules (major histocompatibity complex-Ⅱ, CD80, CD86) were significantly decreased (F=14.708, 22.503, 12.595, respectively, all P<0.05), and DC-IL-10 significantly inhibited T lymphocyte proliferation (F=50.295, P<0.05). When compared with liver fibrosis group, serum alanine aminotransferase and aspartate transaminase were decreased in DC-IL-10 treated group (all P<0.05), other parameters including inflammatory factors (tumor necrosis factor α, IL-6, IL-1β) reduced (all P<0.05), the proportion of regulatory T cells (Treg) increased (F=6.742, P<0.05), pathological damage improved, the expression of Wnt3a, α-SMA and β-catenin mRNA and protein significantly reduced in DC-IL-10 treatment group(all P<0.001). Conclusions DC-IL-10 induces elevation of Treg for immune tolerance, as well as inhibition of inflammatory response, block of Wnt/β-catenin signaling pathway, which translates into improvement of liver fibrosis.

Objective:To evaluate the efficacy of vitamin D supplementation for prevention of spontaneous bacterial peritonitis (SBP) in patients with decompensated liver cirrhosis of hepatitis B.Methods:A total of 172 patients with decompensated cirrhosis of hepatitis B admitted in Jinhua Hospital affiliated to Zhejiang University School of Medicine from January to December 2021 were randomly divided into two groups with 86 cases in each group. Patients in both groups received conventional antiviral and symptomatic treatment; while patients in the intervention group received additinal oral vitamin D drops (800 IU/d) for 6 months. After 6 months of treatment, the incidence of SBP and the serum biochemical indexes were compared between two groups. SPSS 21.0 statistical software was used for data analysis.Results:After 6 months of treatment, the incidence of SBP in the intervention group(5.81%, 5/86) was significantly lower than that in control group(30.23%, 26/86)( χ2=19.210, P<0.01). The serum 25-(OH)D level in intervention group was significantly higher than that in the control group ( t=13.425, P=0.018), while the levels of CRP, PCT and IL-6 in intervention group were significantly lower than those in control group ( t=17.312, 10.353 and 12.218, P<0.01 or <0.05). Conclusion:Vitamin D adjuvant therapy can increase serum 25-(OH)D level, decrease serum CRP, PCT and IL-6 levels, and effectively reduce the incidence of SBP in patients with decompensated cirrhosis of hepatitis B.

OBJECTIVE: To analyze the roles of multidisciplinary team (MDT) in the diagnosis and treatment of suspected cases of coronavirus disease 2019 (COVID-19). METHODS: The clinical data of 48 patients with suspected COVID-19 admitted in Jinhua Municipal Central Hospital from January 21, 2020 to March 20, 2020 were retrospectively analyzed. RESULTS: In the 48 suspected cases, 18 were diagnosed with COVID-19, and 30 were excluded. Each of the confirmed cases were discussed among MDT for 2 to 12 times with an average of (4.7±3.2) times; while for non-COVID-19 patients were discussed for 2 to 4 times with an average of (2.3±0.6) times. With the guidance of MDT, one COVID-19 patient was transferred to designated provincial hospital after effective treatment; one patient complicated with acute cholecystitis underwent gallbladder puncture and drainage; and COVID-19 was excluded in a highly suspected patient after alveolar lavage fluid examination. Except one transferred patient, all 17 confirmed COVID-19 patients were cured and discharged. There was no cross-infection occurred in suspected patients during the hospitalization. There were no deaths and no medical staff infections. CONCLUSIONS The efficiency of diagnosis and treatment for suspected COVID-19 patients can be improved with MDT, particularly for complicated cases.

OBJECTIVE: To analyze the roles of multidisciplinary team (MDT) in the diagnosis and treatment of suspected cases of corona virus disease 2019 (COVID-19). METHODS: The clinical data of 48 patients with suspected COVID-19 admitted in Jinhua Central Hospital from January 21, 2020 to March 20, 2020 were retrospectively analyzed. RESULTS: Of the 48 suspected cases, 18 were diagnosed with COVID-19, and 30 were excluded. Each of the confirmed cases were discussed among MDT for 2 to 12 times with an average of (4.7±3.2) times; while for non-COVID-19 patients were discussed for 2 to 4 times with an average of (2.3±0.6) times per case. With the guidance of MDT, one COVID-19 patient was transferred to designated provincial hospital after effective treatment; one patient complicated with acute cholecystitis underwent gallbladder puncture and drainage; and COVID-19 was excluded in a highly suspected patient after alveolar lavage fluid examination. Except one transferred patient, all 17 confirmed COVID-19 patients were cured and discharged; there was no cross-infection occurred in suspected patients during the hospitalization; there were no deaths and no medical staff infections. CONCLUSIONS The efficiency of diagnosis and treatment for suspected COVID-19 patients can be improved under MDT mode, particularly for complicated and refractory cases.
