The effect on the growth and phenol degradation of the thermophilic strain BF80 by seventeen different metal ions were studied. The results showed that the metal ions certainly affected the growth and phenol degradation of the strain BF80. At the concentration of 0.01%,contrasting to the comparison,the growth and phenol degradation of the strain BF80 were restrained intensively by the metal ions of Cu2+,Zn2+,Co2+,Ba2+,Hg2+,Ni2+,Ag+,Al3+. The metal ions of Cr2+ restrained the phenol degradation of BF80 strongly while Cr2+ restrained the growth of BF80 faintly. The metal ions of Sn2+,Fe2+,Fe3+,Pn2+ restrained the growth and phenol degradation of the strain BF80 at a certain concentration,and the effect of inhibition in-creased with the increase of the concentrations of the metal ions. At the low concentration of Mn2+ or Mo2+,the growth and phenol degradation of the strain BF80 were increased,but if the concentration beyond the 0.1%,the growth and phenol degradation of the strain BF80 were inhibited. At the different concentration of Ca2+ or Mg2+,the growth of the strain BF80 were increased and the phenol degradation were accelerated,but the max rate of phenol degradation by BF80 was not influenced obviously. When the medium was added themixture of metal ions of Mo2+ and Mn2+,the strain BF80 grew better,but the rate of the phenol degradation was lower than that of single Mo2+ and Mn2+.

OBJECTIVETo compare the differences in the clinical efficacy between Guan's quadruple therapy for kidney disease and the conventional western medication in the treatment of chronic renal failure (CRF).

METHODSEighty patients were randomized into an observation group and a control group, 40 cases in each one. In the observation group, besides the physician instruction of low protein and low phosphorus diet in the two groups, Guan's quadruple therapy for kidney disease was applied, including (1) the isolated herbal moxibustion at Shenshu (BL 23) and Pishu (BL 21), or Ganshu (BL 18), Zusanli (ST 36) and Guanyuan (CV 4) alternatively; (2) acupuncture at the auricular points such as shen (CO10), jiaogan (AHR6), Shenshangxian (TG2), fei (CO14) and pizhixia (AT4); (3) injection of mixture of astragalus injection and lidocaine injection at Feishu (BL 13), Pishu (BL 21), Shenshu (BL 23) and the others; (4) modified Shenshuai Yihao decoction according to syndrome differentiation. In the control group, the conventional western medication was used. After 6 months of treatment, the differences were observed between the two groups in the clinical efficacy, serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine (Ccr) and 24 h urine protein quantitation (UPQ).

RESULTSIn the observation group, after treatment, the remarkably effective rate was 50.0% (20/40) and the total effective rate was 82.5% (33/40), which were superior to 25.0% (10/40) and 45.0% (18/40) in the control group (both P < 0.05). After treatment, the levels of Scr, BUN and 24 h UPQ were reduced apparently (all P < 0.05), and the level of Ccr was increased apparently in the two groups (both P < 0.05). After treatment, the levels of Scr, BUN and 24 h UPQ were reduced much more apparently in the observation group as compared with those in the control group (all P < 0.05).

CONCLUSIONGuan's quadruple therapy for kidney disease achieves a better efficacy on CRF compared with the conventional western medication. This therapy improves renal functions, relieves clinical symptoms and physical signs and benefits the life quality of patients.

This article briefly reviews their biochemical characteristics, isolation, gene cloning, biological and neuropharmacological activities, as well as their potential applications.

Objective To investigate the acute phase adverse effects and influencing factors of adverse effects of diphosphonate treatment in the elderly patients with primary osteoporosis.Methods A total of 208 patients [male 25 patients,female 183 patients,age 60 ～ 93 with a average of (75.51 ± 7.73) years] with primary osteoporosis were selected from 1 Jan 2012 to 30 Nov 2015,admitted to Department of Geriatrics.According to the serious condition of osteoporosis and willingness of patients,208 patients were divided into zoledronic acid treatment group,alendronate treatment group,and pamidronic acid group,and received corresponding diphosphonate treatment.All kinds of adverse reactions of diphosphonate in each treatment group were closely to be observed after administration of diphosphonate in 3 days and 7 days.Results The incidence rate of adverse reactions in the zoledronic acid treatment group (59/134,44.03％;60/134,44.78％) was obviously higher than that in the alendronate treatment group (1/57,1.75％;1/57,1.75％),and the pamidronic acid group (3/17,17.65％;3/17,17.65％) after treatment of diphosphonate in three and seven days (P ＜ 0.05).In different generations,the incidence rate of adverse reactions in the zoledronic acid group and the pamidronic acid group after treatment of diphosphonate in three and seven days was not statistically significant (P ＞ 0.05).There were three patients suffering from severe acute kidney injure (AKI) and three patients suffering from hypokalemia in the 134 patients treatment with zoledronic acid.Conclusions There are obvious differences in the incidence rate of acute phase adverse reactions in the osteoporosis patients who received different treatment policy (P ＜ 0.05).The safety issues in the kidney function and electrolyte abnormality (such as hypokalemia) should be paid much enough attention in the primary osteoporosis patients who receive zoledronic acid treatment.

Objective: To explore the influence of estradiol benzoate in induction of BALB/c mouse systemic lupus erythematosus model. Methods: Gonadectomied BALB/c mice were immunized with homologous spleen cell activated by concanavalin A three times,and at the same time injected with different doses estradial benzoate. Serum antinuclear antibody, antihistone antibody and estradiol in serum and kidney tissue homogenate were detected by enzyme linked immunosorbent assay. Kidney lesions were detected by hematoxylin-eosine(HE) and periodic acid-Schiff(PAS) staining, and by transmission electron microscope for detecting electron-dense agent as well as by direct fluorometric method for detecting immunoglobulin G antigen-antibody complex. Results: BALB/c mice immunized with homologous spleen cells activated by concanavalin A all developed systemic lupus erythematosus, but a statistically significant variation was observed in both autoantibody production and kidney damage were observed with a statistically significant variatron in the groups receiving different dosage of estradiol benzoate group(P

Background Oxidative damage may cause the functional dysfunction and death of retinal vascular endothelial cells(RVECs),and further leads to the development of retinal vascular diseases.Fufang xueshuantong has a therapeutic effect on retinal vascular diseases,but little is known about its molecular mechanism.Objective The goal of this study was to investigate the protective effects and mechanism of fufang xueshuantong on injury of human RVECs induced by tert-butyl hydroperoxide(t-BHP).Methods Human RVECs were isolated from healthy donor eyes and primarily cultured and then identified by flow cytometry.The third to fifth generations of cells were used in this experiments.The fufang xueshuantong solution of 0.0625,0.1250,0.2500,0.5000 and 1.0000 g/L were added in the cuhure plate with 5 × 104/L cells respectively in the experimental groups,and t-BHP of 75,100,200 and 300 μ.mol/L were added in the model control groups.MTT was used to detect the A490and survival rate of RVECs.The apoptotic rate and death rate of the cells were evaluated by double staining of Annexin V-FITC/PI.Morphology of human RVECs were examined using invert microscopy and Hoechst33258 staining.The expressions of nitro tyrosine (a marker of oxidative damage of protein)and 8-OHdG(a marker of oxidative damage of DNA)in human RVECs were assessed by the immunofluorescence staining.Western blot was used to detect the expressions of nuclear factorkappa B(NF-KB),p53,bcl-2 and bax after 6,12,24 hours t-BHP action.This study was approved by the Ethic Committee of Zhongshan Ophthalmic Center.Results No significant difference was found in A490value among the normal control group,0.0625,0.1250,0.2500,0.5000 and 1.0000 g/L fufang xueshuantong groups(F =1.989,P＞0.05).The survival rates of the cells were lower in 75,100,200 and 300 μmol/L t-BHP groups compared with corresponding fufang xueshuantong groups(t =14.57,13.82,21.51,32.64,P＜ 0.01).The percentages of normal cells were evidently lower in 75,100,200 and 300 μmol/L t-BHP compared with corresponding fufang xueshuantong groups(t=14.908,5.495,17.165,26.330,P＜0.01).The numbers of deformation and death of the human RVECs increased as the elevated concentration of t-BHP,but those in fufang xueshuantong groups were less than the t-BHP groups under the invert microscopy.Compared with t-BHP groups,the expressions of nitro tyrosine,8-OHdG,NF-KB,p53 and bax were lower but the expression of bcl-2 was higher in human RVECs with the statistically significant differences(P＜0.05).Fufang xueshuantong at the concentration of 0.2500 g/L showed maximally protective effect on human RVECs.Conclusions Fufang xueshuantong protects human RVECs against the t-BHP-induced injury through downregulating the expression of NF-kB,p53,bax and up-regulating the express of the bcl-2 protein.

Objective To investigate the expression and clinical significance of tumor infiltrating dendritic cells(TIDCs) within gastric tumor tissues.Methods Immunohistochemistry(IHC),in-situ hybridization(ISH) and flow cytometry were applied to detect the expression of S100,CD83 mRNA and CD83 on DCs in 45 gastric adenocarcinoma tissues.The co-relationship of the S100 and CD83 expression with clinical(pathological) features was analyzed.Results IHC showed that S100 expression was unevenly distributed(within) 42 cancer tissue and CD83 was only expressed in tumor-adjacent tissue and normal tissue.ISH showed that CD83 mRNA was limitedly expressed within 7 samples.S100 expression had no significant(correlation) with clinical pathological features,while CD83 reversely correlated with TNM stages.Detected by flow cytometry,CD83 was expressed in low level in all 45 gastric cancer tissues and negative correlations were found with lymph node metastasis and TNM stages of gastric cancer(r=-0.879,P

To establish kinetic assay method for the analysis of hemolysis and to investigate dynamic hemolytic process of polysorbate 80. The UV-VIS spectrum of heme changes when hemoglobin is released continuously during the hemolytic process. Therefore, dynamic hemolytic curve was determined as a new way to characterize the kinetic process of interaction between polysorbate 80 and red blood cells. The effect of polysorbate 80 on blood cells could be perfectly investigated by the hemolytic dynamics. Dynamic hemolytic parameters of polysorbate 80 were calculated according to the hemolytic curves. The constants of hemolytic rate and maximum hemolytic rate of polysorbate 80 had fine linear relationships at the range of 1-20 mg x mL(-1) and 5-20 mg x mL(-1), respectively. In comparison with the present official method such as macroscopic observation and static spectrophotometric methods, kinetic spectrophotometry has the advantages of real time, on-line determination, sensitive, objective, good reproducibility and 2-dimensional information acquired. Therefore, as a biological technique, kinetic spectrophotometry could be applied to evaluate the quality of polysorbate 80 and to screen other solubilizing excipients.

Objective To investigate the expression of p21 and p53 in renal interstitial fibrosis rats and the effect of enalapril on it. Methods Sprague-Dawley rats were randomly divided into 3 groups, shame operation rats group, unilateral urethral obstruction and enalapril treatment group. Histological chan-ges were observed by Masson stain. The expression of p21 mRNA and p53 mRNA was detected by RT-PCR. Results With degree of interstitial fibrosis aggravating, the expression of p21 and p53 increasing,p21 and p53 expression of UUO rats at every time point were positive correlative. Enalapril can inhibit the expression of p21 and p53. Concinsion p21 and p53 expression increased in UUO rats renal cortex and enalapril can significantly inhibit its expression, p21 may participate in the pathogenesis of renal tubule-in-terstitial fibrosis through p53 pathway.
