Objective To observe the effect of combination treatment of lamivudine,tripterygium glycosides and ahalysantinfarctasum on hepatitis B virus associated glomerulonephritis(HBV-GN)in children.Methods Sixty cases with HBV-GN were divided into 2 groups randomly.The observation group was treated with lamivudine(100 mg/d),tripterygium glycosides [0.5 mg/(kg?d)],and ahalysantinfarctasum [0.01 U/(kg?d),3 d];the control group were treated with tripterygium glycosides 0.5 mg/(kg?d)only.The effect was judged after treatment according to clinical research guide principle of chronic nephritis treated with new Chinese materia medica and clinical research guide principle of viral hepatitis treated with new Chinese materia medica.Statistic analysis were performed with the PEMS 3.1 for windows statistic program package.Values were considered statistically significant at P

Objective Cancer radio-therapy may induce bone damage of the patients.collagen type I gene expressions in osteoblast after radiation indicates the influence of radiation on the function of early and late osteoblast.Methods Bone marrow stromal cells were differentiated into osteoblasts in vitro.and the characteristics was indentified.The collagen type I expressions in early and late stage osteoblasts exposed to 1～4Gy radiation were examined by RT-PCR.Results Compared to control group,collagen type I gene expressions increased in early osteoblast after 1～3 Gy radiation (P＜0.05),while the gene expressions in late osteoblast that cultured 10 days decreased.Collagen type I gene expression in late stage ostoblast after 4 Gy irradiation was greatly higher than that in early stage osteoblast (P＜0.01).Conclusion After 1～3 Gy irradiation,the collagen type I expression in early osteoblast was enhanced,indicating the increased ability of bone formation.The exposure to 1～3 Gy decreased collagen type I expression in late osteoblast and weakened the ability of bone formation.The result of high expression of collagen type I in late osteoblast after 4 Gy irradiation may be the manifestation of compensatory function.

Objective:To investigate the expression of HIF-1?and its relationship with angiogenesis in osteosarcoma.Methods: Osteosarcoma MG-63 cells were cultured in vitro under hypoxia and mimic hypoxia conditions.Thirty paraffin-embedded osteosarcoma tissues and 20 fresh frozen osteosarcoma specimens were collected.The mRNA and protein expression of HIF-1?and VEGF were detected by RT-PCR,Western blotting,ELISA,and immunohistochemistry methods.The mean vessel density(MVD)were also calculated.Results:The mRNA level of HIF-1?had no change under hypoxia and minic hypoxia conditions,whereas the protein expression was increased dramaticaly.The mRNA and protein expression of VEGF was significantly increased under hypoxia and minic hypoxia conditions.The positive rate of HIF-1?mRNA(90%)and VEGF(100%)in 20 fresh frozen tissues were higher than those of the para-tumor tissues(P

Results All pa-tients were free from infection,reamputation and fracture-related complication. Conclusion After the arrival of large number of the wounded in the station hospitals.efficient organization of station hospitals,comprehensive evaluation of the patients'condition,effective detailed therapeutic plans and careful man-agement of the medical complications can attain sound results.

To evaluate the efficacy and safety of new drugs of traditional Chinese medicine (TCM) for acute upper respiratory tract infection (common cold).

One hundred and fifty patients with impacted upper-ureteral calculi were treated with ureteroscopic lithotripsy (URSL group,n =58),percutaneous nephrolithotomy (PCNL group,n =42) or retroperitoneal laparoscopic ureterolithotomy (RPLU group,n =50) from April 2011 to August 2015.The operative time,length of postoperative hospital stay,stone-free rate and the incidence of postoperative complications were observed and compared among three groups.The stone-free rate of URSL group one month after surgery was 77％,which was significantly lower than PCNL (95％) and RPLU groups (100％) (P ＜ 0.05).But the operative time and length of postoperative hospital stay of URSL group [(37.2 ± 5.6)min,(3.9-±0.8)d] were significantly shorter than PCNL group[(75.2 ±6.7) min,(7.9 ±0.9))d] and RPLU group [(65.3 ± 6.1) min,(8.7 ± 0.9) d] (all P ＜ 0.05).The postoperative complication rates of three groups were 8％,10％ and 10％,respectively.

Objective To probe the oprⅠ gene in rat model with Pseudomonas aeruginosa septicemia by FQ-PCR,and compare the sensitivity and specificity between FQ-PCR and traditional germiculture,and check the change of oprI gene before and after the antibiotic therapy as to rapidly judge its sensitivity.Methods The standard Pseudomonas aeruginosa with five different concentration were prepared,the drug-sensitive test wbre used to find lhe sensitive antibiotics.120 SD rats were random divided into five groups,five different concentrations of Pseudomonas aeruginosa were injecked into the rats with the same volume.Six rats of each group were picked up for taking blood for culture at the time points of Oh,12h,24h,and 48h after narcotization.Finally,the oprⅠ gene of each blood samples were checked with FQ- PCR.72 rats were random divided into three groups,therapeutic group,treated group and control group.Pseudomonas aeruginosa with the concentration of 1×109 CFU/ml were injected into those rats.Sensitive antibiotics,insensitive antibiotics and 0.9% NaCl were given to the therapeutic,treated and control group rats respectively.Six rats of each group were picked up for taking blood for culture at the time point of Oh,12h,24h,and 48h after narcotized.Finally,the oprⅠ gent of each blood sample were checked with FQ-PCR.Results The blood culture were positive in each period of the concentrations 1×109 CFU/ml and 1×108 CFU/ml.Results of FQ-PCR showed that the copy number decreased with time going,all of which were positive.The blood culture were positive at the time points of Oh and 12h with the concentrations of 1×107 CFU/ml and 1×106 CFU/ml,were positive with concentration of 107 CFU/ml at the time point of 24h,but negative with concentration of 107 CFU/m at the time point of 48h,and negative with the concentration of 1×106 CFU/ml at the time points of 24h and 48h.The blood culture were negative in each period of the concentration of 1×105 CFU/ml,and the results of FQ-PCR were negative.The blood culture were positive in each period of both treated and control group,but negative in each period of therhpeutic group,all the results of FQ-PCR were positive.Conclusion The coincidence rate between the method of FQ-PCR and trgditional germicuhure were 100%.Though the sensitivity of FQ-PCR was not increased,the time needed by diagnosis was shorter After treated with effective antibiotic,fhe sensitivity of FQ-PER to diagnosis Pseudomonas aeruginosa septicemia was higher than that of traditional germicuhure,and the experiment time was shorter.Detected the changes of the oprⅠ gene copies number may be helpful to estimate the sensitivity of antibiotic.

Aims The purpose of this study is to investigate thediagnostic value of SWEfor fibrosis in patients with CHBand the factorsinfluencing the accuracy. Methods From July 2013 to October 2015, 261 patients with CHB were recruited from the First Affiliated Hospital of Sun Yat-sen University.All patients received SWE, anthropometry measurement, blood cell count, liver function test and virological indicators measurement. Liver fibrosis was staged from F0 to F4 by METAVIR scorebased onliver biopsy results of 133 CHB patients , while 128 patients were diagnosed as decompensated cirrhosis. Diagnostic accuracyof SWE were evaluated by Receiver Operating Characteristic Curve (ROC) using liver hepatic pathology and decompensated cirrhosis as gold standards. Logistic model was used to find out confounding factors that influence the accuracy of SWE. Results The Area Under ROC (AUC) for liver stiffness measurement with SWE were 0.891, 0.932 and 0.910 for the diagnosis of significant fibrosis (≥ F2), advanced fibrosis (≥F3) and cirrhosis (F4), respectively. A multifactor logistic regression combined modelwas built and showed that hepatic steatosis will decrease the accuracy of SWE. Conclusion SWE could be a valuable method for the noninvasive liver fibrosis assessment. The accuracy of SWE may be influenced by hepatic steatosis.
