Objective To observe the effect of ciclosporin(CsA) treatment on children with refractory nephrotic syndrome(NS).Met-hods Combination treatment of CsA[3-5 mg/(kg?d)] and prednisone were given 55 cases with refractory NS,in which including steroid-dependent NS(SDNS) 3 cases,steroid-resistant NS(SRNS) 22 cases,frequent-relapses NS(FRNS) 30 cases.Concentration of CsA was maintained 100-200 ng/L.Course of treatment was 10 months,the dose was tapered gradually in 4 months.Scr,BUN,Alb,ALT,Ccr,Chol,24 hours urine protein quantitation was measured before and after CsA treatment.Side effect of CsA was observed at the same time.SPSS 13.0 software was used to analyze the data.Results Forty-one cases(74.5%) were complete remission,6 cases(10.9%) were partial remission,total effective rate was 85.5%.Remission rate was 97.6% in simple type NS,50.0% in nephritis type NS,100% in SDNS and FRNS groups,63.6% in SRNS group.In group minimal change disease(MCD),the remission rate was 100.0%,while 60.0% in group mesangial prolife-rative glomerulonephritis(MsPGN),and 42.9% in group focal segmental glomerulosclerosis(FSGS).Fifteen cases(31.9%) relapsed when the dose of CsA was tapering.The adverse effects included hairiness(55 cases),gum hypertrophy(16 cases),hypertension(9 cases),gastroi-ntestinal tract reaction(8 cases),but no obvious nephric adverse effects were observed during the treatment process.Conclusion CsA is safe and effective on refractory NS children,especially to those with SDNS,FRNS and MCD.

Objective To study the distribution of IL-10 and TNF gene polymorphisms in patients with gastroduodenal diseases in Hubei Han ethnic and their association with Helicobacter pylori (Hp) infection. Methods Six hundred and five patients with gastroduedenal diseases (196 chronic gastritis, 189 gastroduodenal ulcer and 220 gastric cancer) as well as 624 healthy controls were genotyped with PCR-RFLP method for IL-10-1082,-819,-592 and TNFα-308, lymphotoxin-α (LTα) Nco Ⅰ and AspH Ⅰ gene polymorphisms. Hp infection status was determined with ELLS& Results (1) There was significant difference of IL-10-1082 AG + GG genotype among the gastric cancer group with the non-malignant gastric diseases groups and healthy control group (P <0. 05). There was no significant difference of IL-10-592 and -819 gene polymorphisms among gastric cancer patients,non-malignant gastric disease patients and healthy controls (P>0. 05). The genotype frequencies of IL-10-819 were the same as those of IL-10-592. (2) Frequency of IL-10-1082 AG + GG genotype in gastric cancer patients with positive Hp was significantly higher than that in the other three groups (P < 0. 05). (3) Frequency of LTα Nco I AG genotype in gastric cancer patients with Hp infection was signiilcandy higher than that in Hp positive healthy controls (P < 0. 05). There were no other associations between TNFα-308, LTα Nco Ⅰ and AspH Ⅰ gene polymorphisms and Hp infection in gastroduodenal diseases. Conclusions (1) Allele AG + GG of IL-10-1082 was associated with gastric cancer in Han nationality of Hubei province. (2) IL-10-1082 AG + GG,LTct Nco ⅠAG heterozygous genotype may be associated with Hp infection in patients with gastric cancer in Han nationality of Hubei province.

AIM:To investigate the role of high glucose in primary hepatocytes of mice fed with a high fat di-et.METHODS:Male C57BL/6J mice were fed a high fat (45%of calories) diet ad libitum for 6 weeks to induce hepatic steatosis.Primary hepatocytes were isolated from the mouse liver by the 2 step collagenase perfusion method .The cells were incubated in low glucose ( 5 mmol/L ) , low glucose plus mannitol ( 30 mmol/L ) , or high glucose ( 35 mmol/L ) DMEM medium for 12 h.The cell viability , apoptosis , mitochondrial membrane potential , and caspase enzymatic activities were measured.Furthermore, proteins related to the stress-sensitive signaling pathway of regulating high glucose-induced apoptosis in primary hepatocytes were determined by Western blotting .RESULTS:Incubation with 35 mmol/L glucose re-sulted in a significant decrease in cell viability and an increase in apoptosis , whereas mannitol had no significant effect on the cell viability or apoptosis .A progressive depolarization of the mitochondria , an increase in cytosol cytochrome C and a dramatic decrease in mitochondrial cytochrome C in high-glucose stressed hepatocytes were observed .The enzymatic activi-ties of caspase-9 and caspase-3, but not caspase-8, were significantly increased in high glucose-stressed hepatocytes ( P<0.05).High glucose treatment suppressed the expression of Bcl-2 and Bcl-xL, while it increased the expression of the pro-apoptotic factor Bax .CONCLUSION:High glucose stress reduces mitochondrial membrane potential , initiates mitochon-dria-mediated apoptotic pathways and promotes apoptosis of hepatocytes with steatosis .This may be an important pathologi-cal mechanism of hyperglycemia-induced progression of nonalcoholic fatty liver disease .

Objective To develop a new method, capillary electrophoresis(CE) based on molecular beacon(MB),for rapid detection of polymerase chain reaction(PCR).To explor the roles of the IL-13 gene exon4 A2044G single nucleiotide polymorphism(SNP) in the pathogenesis of bronchial asthma.Methods The IL-13 exon 4 was amplified by PCR with genomic DNA used as templates from 20 healthy persons and 32 patients with dominantly allergic familial history living in the north of china.Then separating the amplification with capillary electrophoresis followed by hybridization of molecular beacons into the PCR product which were sequenced in the end. Results Detected with CE-MB method,there was significant difference in the distribution of A/G in IL-13exon 2044,A allele frequency was higher in asthma compared with normal controls,same as sequencing. Conclusion The method of capillary electrophoresis based on molecular beacon(MB-CE) is able to be developed as a clinical detecting method for genetic variation diseases.IL-13 A2044G SNP is important in the asthmatic mechanism.

OBJECTIVE:To provide reference for further formulation of the rational use of vancomycin. METHODS:Retro-spective analysis was conducted on the related information of discharged patients who intravenously used vancomycin from Jun. 2013 to Dec. 2014. RESULTS:178 patients were enrolled,with average age of 59.6 and 73.60% male,who were mainly with lung infectious(74.72%). Support examinations were sufficient before using of vancomycin. 66.29% patients were empirically giv-en vancomycin with pathogenic detection rate of 85.39%. 71.91% patients were conducted therapeutic drug monitoring with only 47.54% of first blood samples achieved the target range. CONCLUSIONS:Vancomycin application is generally rational in our hos-pital. However,issues like duration of empirical therapy,rational therapeutic monitoring,and individualized start dosing still need to be noticed.
