Renal involvement is common in systemic lupus erythematosus(SLE).Treatment of lupus nephritis includes immunosuppressive and supportive therapy.The intensity of immunosuppressive therapy depends on the clinical and renal pathological disease activity.The long-term targets of treatment are to prevent lupus nephritis relapse and protect renal function.Complete remission is the goal in the induction phase,and long-term treatment is necessary in the maintenance phase.Individualization therapy and the side effects of immunosuppressive agents should be paid more attention.

Objectives To reveal the association between Helicobacter pylori infection and creatinine clearance rate in elderly patients with hypertension.Methods A total of 600 elderly hypertensive patients with different degrees of renal impairment and helicobacter pylori(HP)infection were randomly selected from Department of Health Care,General Hospital of Tianjin Medical University from 2010 to 2015.Serum creatinine concentration detection was conducted and creatinine clearance rate was calculated.Patients were divided into HP infection group(n =254)and non-HP-infection group (n =346).The multiple logistic regression analysis showed the correlation between Helicobacter pylori infection and decreased creatinine clearance rate.Results Creatinine clearance rate was significantly lower in HP-infection group[(61.1 ± 12.7)ml/min] than in non-HP-infection group[(78.5 ± 11.9) ml/min,P =0.014].Multifactorial logistic analysis revealed that Helieobacter pylori infection was significantly associated with decreased creatinine clearance rate(OR=3.5 18,95 ％ CI:1.105～4.918,P =0.011).Conclusions Helicobacter pylori infection is significantly related with decreased creatinine clearance rate in elderly patients with hypertension.

Objective To investigate the mechanism of electroacupuncture in the treatment of non-alcoholic fatty liver disease(NAFLD).Methods Thirty-three male SD rats were randomized into 2 groups:normal control group(n=11,fed with normal food)and experimental rats(n=23,fed with high-fat food).Eight weeks later,3 rats were randomly selected from the 2 groups respectively and killed to undergo pathological examination of the liver.When the establishment of experimental rats was confirmed,the remaining 20 experimental rats were divided into 2 equal subgroups:NAFLD group(fed continuously with high-fat food)and electroacupuncture treatment group(fed continuously with high-fat food and received the treatment 15 min per day,once a day for 4 weeks).Then all rats were killed to detect the serum levels of fasting blood glucose(FBG),fasting insulin(FINS)and free fatty acids(FFA),liver contents of malondialdehyde(MDA),glycerin tripalmitate(TG)and total cholesterol(TC),and the activities of liver superoxide dismutase(SOD)and glutathione(GSH).Liver pathological changes was examined.Results Compared with NAFLD group,electroacupuncture reduced the serum levels of FBG,FINS and FFA(P

Objective To analyze the clinical and pathological characteristics of ANCA associated systemic vasculitis(AASV) with immune complex deposition in kidney and compare with that of pauci-immune AASV. Methods Patients with AASV, admitted in our hospital in last 5 years, were retrospectively studied. The clinical and pathological characteristics were compared between patients with immune complex deposition and patients with pauci-immune deposition. Results There were eitht patients with immune complex deposition (five with IgM deposition, two with IgA deposition and one with IgG deposition) and 32 patients with pauci-immune deposition. There was no significant difference in age, gender, type of ANCA, interval between onset of vasculitis and renal biopsy, clinical manifestations and short-term renal survival rate between the two groups. Patients with immune complex deposition had a higher predromal infection rate ( P

0.05), respectively. Conclusion: IgA1 could bind to HUVEC directly, and the binding capacities of DesIgA1 and Des/DeGalIgA1 to HUVEC were significantly higher than that of normal IgA1. Serum IgA1, especially deglycosylated IgA1, might play some role in vascular lesions of IgAN.

Objective: To investigate the prevalence of anti-endothelial cell antibodies(AECA) and its possible role in the pathogenesis of propylthiouracil (PTU) induced ANCA positive vasculitis. Methods: Sera from 11 patients with PTU induced ANCA positive vasculitis and 10 patients with PTU induced ANCA but without clinical vasculitis were studied. Soluble proteins from in vitro cultured human umbilical vein endothelial cells were used as antigens and immunoblotting technique was performed to identify the specific target antigens. Results: In patients with PTU induced ANCA positive vasculitis group, 10 of the 11 patients in active phase were AECA positive and 7 of the 10 patients turned to negative in remission. AECA consisted of a group of heterogeneous antibodies. In patients with ANCA positive but without vasculitis, none was AECA positive. Conclusion: AECAs recognizing a variety of antigens could be found in sera from patients with PTU induced ANCA positive vasculitis and they had a much closer association with vasculitic disease activity compared with ANCA.

ObjectiveTo observe the effect of reverse acupuncture by stages combined with facilitation techniques on motor function of stroke patients.Methods114 stroke patient were randomly divided into the treatment group (n=68) and control group (n=46). The patients of the treatment group were treated with reverse acupuncture by stages combined with facilitation techniques. Those of the control group were treated with general acupuncture combined with facilitation techniques. The period of treatment of two group was 30 days.ResultsAfter treatment, the scores of motor function and activities of daily living of the treatment group were significantly higher than that of the control group ( P<0.01).ConclusionThe reverse acupuncture by stages combined with facilitation techniques can obviously improve motor function of stroke patients.

Gene knockout by ZFNs (zinc-finger nucleases) is efficient and specific, and successfully applied in more than 10 organisms. Currently, it is unclear whether this technology can be used for knocking-out enhanced green fluorescent protein (EGFP) gene in transgenic goats. Here we constructed and used ZFN-coding plasmids to produce genetic knockouts in the cells of cloned fetus produced from donor cells by microinjection of EGFP gene. Following introduced plasmids into caprine primary cultured fetus fibroblasts by electroporation, targeting of a transgene resulted in sequence mutation. Using the flow cytometric analysis, we confirmed the disappearance of EGFP expression in treated cells. Sequence from PCR products corresponding to targeted site showed that insertion of a G into the exon of EGFP resulted in frame shift mutation. These results suggest that ZFN-mediated gene targeting can apply to caprine fetus fibroblasts, which may open a unique avenue toward the creation of gene knockout goats combining with somatic cell nuclear transfer.

Objective To evaluate the therapeutic effects and dose-effect relationships of different doses of the blood-cooling and blood flow-promoting drugs(凉血活血方) on radiation-induced lung injury of rat.Methods Seventy-two Wistar rats were randomly allocated into four groups: irradiation group(group A),small-dose group(group B,9 g?kg-1?d-1),middle-dose group(group C,18 g?kg-1?d-1) and high-dose group(group D,36 g?kg-1?d-1).All groups were repeatedly exposed to small dose of X-ray in the right hemi-thorax,and then the mice were sacrificed at different time points.The living animal features,the macro-changes of lung were observed,and pulmonary histopathological changes in all the groups were investigated,and the results of observation were compared.Results The symptoms of red patches around the nose and dry stool in groups C and D were less than those of groups A and B.After 26 weeks,lung coefficient in groups B,C and D was the same as that in group A,but right lung wet weights and lung coefficients at each time point in groups B,C and D were significantly lower than those in group A,and during 5th week,the right lung wet weights in groups C and D were obviously lower than the weight in group B(all P
