Objective To investigate the effects of combination therapy with ACEI and aldosterone receptor antagonist on Cys-C and urinary microprotein regulation.Methods Patients were randomly divided into two groups.The control group received benazepine hydrochloride only.The experimental group received benazepine and spironolactone treatment.The blood pressure,renal function,24 h urinary protein,Cys-C,GFR,urinary microprotein and the correlation of GFR with Cys-C and urinary microprotein were recorded.Results There was no statistically significant difference between two groups in blood pressure(P>0.05).After treatment,the renal function of the experimental group was significantly improved compared to that of the control group.The 24 h urine protein,Cys-C and urinary microprotein were significantly lower in the experimental group than the control group(P<0.05).GFR was negatively correlated with Cys-C and urinary microprotein.Conclusion The com-bination therapy of ACEI and aldosterone receptor antagonist can improve renal function and reduce 24 h hematuria.GFR fil-tration ability was significantly improved with the reduction of Cys-C and urinary microprotein.

AIM: To assess the role of surface free radicals and electromotive voltage of fibrous mineral dusts in rabbit pulmonary alveolar macrophage injuries induced by fibrous mineral dusts. METHODS: Changes in cell death ratio, malandialdehyde (MDA) and cellur electrophoresis ratio, lactate dehydrogenate (LDH)and superoxide dismitase(SOD) activities were determined, the technique of cell culture and Scanning electron Microscopy were used to examine the change of membranous permeability, charge and cellular shape. RESULTS: Fibrous wollastonite and tabulate clinoptilolite, which had no OH-, had no cytotoxicity, while fibrous sepiolite, fibrous palygorskite, fibrous brucite and chrysolite asbestos damaged pulmonary alveolar macrophages in various degrees because of the different OH- levels. All the six fibrous mineral dusts changed the cellular electrophoresis ratio. CONCLUSION: The surface electromotive voltage of fibrous mineral dusts is not an important factor, and the cytotoxicity of them may be related to OH- levels on the mineral dust surface.

Objective To investigate the regulation of IFN-γ to Th17 response in Chlamydia muridarum (Cm) lung infection in mice. Methods A murine model of pneumonia induced by intranasal inoculation of Cm was used for this study. Anti-mouse IFN-γ McAbs were used to neutralize endogenous IFN-γfollowing Cm lung infection. Control group received the same dose of isotype antibody (IgG2a). Mice were sacrificed at day 7 postinfection. Chlamydial growth in the lung was assessed by immunoenzyme technique.IL-17 and IL-23 mRNA expression in the lung was assayed by RT-PCR and the proliferation of IL-17 + CD4 +T cells in the spleen was assayed by intracellular cytokine staining. Results IFN-γ-neutralized mice exhibited serious disease course, include greater body weight loss, higher organism growth and much more severe pathological changes in the lung compared with control mice. The mRNA expression of IL-17 and IL-23 in the lung and the proliferation of IL-17 + CD4 + T cells in the spleen significantly decreased in the IL-17- neutralized mice. Conclusion IFN-γ was protective in Cm lung infection through up-regulating the antigen specific Th17 responses.

Laparoscopic cholecystectomy (LC) is the first preferred treatment of benign gallbladder diseases such as gallbladder stones and gallbladder polyps, however bile duct injury is a serious complication of LC. Although bile duct injury is a rare complication, improper treatments will seriously affect the quality of life or even threaten life. Therefore, the prevention and correct treatments of bile duct injury in LC are crucial. Based on domestic and overseas researches, the authors investigate risk factors for bile duct injury in LC, share experiences of timely detection, diagnosis and treatment, so as to provide references for hepatic and biliary surgeons.

Objective:To study the expression of forkhead box P1 (FOXP1) in intrahepatic cholangiocarcinoma (ICC), and its clinicopathological and prognostic significance.Methods:The clinical data of ICC patients treated with radical resection at Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 1, 2013 to December 12, 2019 were retrospectively analysed. Of 48 ICC patients, there were 24 males and 24 females, with age of (59.1±10.1) years old (range 42 to 83 years old). Their clinicopathological data, including age, gender, tumor size, degree of differentiation, and staging were recorded. Immunohistochemical method was used to detect the expression of FOXP1 protein in ICC cancer tissues and the corresponding adjacent normal tissues. Kaplan-Meier method was used to calculate survival rates and to construct survival curves of patients. Cox regression model was used to analyze factors affecting prognosis of patients.Results:Forty-eight ICC cancer tissues and 40 corresponding paracancerous tissues were collected. The positive rates of FOXP1 proteins in ICC were significantly lower than the adjacent normal tissues [54.2%(26/48) vs. 92.5%(37/40), χ 2=15.76, P<0.05]. The degrees of tumor differentiation, lymph node metastasis, organ invasion and TNM staging were related to expression of FOXP1 ( P<0.05). Forty-two patients were followed-up with a median follow-up time of 11.5 (7.75, 19.25) months. Cox multivariate analysis revealed that invasion to adjacent organs, lymph node metastasis, high TNM staging (stage Ⅲ) and negative expression of FOXP1 were independent risk factors affecting overall survival of ICC patients. The overall survival and recurrence-free survival of FOXP1-positive ICC patients were 17.5 months and 15.5 months, which were significantly higher than the 14.0 months and 11.1 months, respectively, in FOXP1-negative patients. Conclusion:Negative FOXP1 expression was closely correlated with aggressive biological behavior and poor prognosis of ICC. FOXP1 may be used as new diagnostic and therapeutic targets.
