The third to sixth passage cells were incubated with 25 ng/ml CSF-1 for 0.5,1,3 and 6 h respectively,then the conditioned medium and cells were collected for ELISA and RT-PCR assay respectively.Results:OPG was expressed in the cytoplasm of human dental follicle cells.GSF-1 at 25 ng/ml and 1 h-exposure down-regulated OPG expression in the cells(P

Objective To study the treatment of renal artery stenting for patients with coronary artery heart disease and renal artery stenosis who need coronary atery bypass graft (CABG) and its effect on preventing acute renal dysfunction after CABG. Methods From April 2001 to January 2005, renal artery stenting was carried out in 82 patients (a total of 104 renal arteries) with CHD and renal artery stenosis who needed CABG. Among the 82 patients, 77 of them accompanied with hypertension and 21 of them had abnormal renal function. Heparin was selected as anticoagulant other than anti-platelet drug and low molecular weight heparin before stenting. Results All of the stents were successfully implanted in 104 renal lesions without complication. Blood creatinine (Cr) reduced in 9 patients with renal dysfunction by the time of discharge. Three patients had blood Cr increased provisionally after stenting. Four patients with normal pre-operational renal function showed transient increase in blood Cr after stenting. All of the patients with transient blood Cr elevation had bilateral renal artery stenosis. Conclusion Renal artery stenosis may cause acute renal failure after CABG. Pre-CABG renal artery stenting may prevent the occurance of acute renal failure after operation.

ObjectiveTo evaluate the clinical efficacy of intravenous catheter in combination with ultraviolet radiation for postherpetic neuralgia (PHN).Methods96 patients with PHN were randonly divided into three groups.Intravenous catheter plus UVB radiation was given in the test group(32 patients).Intravenous catheter or UVB radiation was only given in two control groups (32 patients/group), respectively.ResultsThe total effective rate in the test group was 96.88％ (31/32) and the average onset time was 1.55 days.However,the total effective rate in two control groups was 81.25％ (26/32) and 68.75％ (22/32) ,and the average onset time was 2.48 days and 7.41days.There was a statistical difference observed in curative rate (x2 = 5.33,42.42, P ＜ 0.05 or P ＜ 0.01), the total effective rate(x2 =4.59,8.89,P＜0.05 or P＜0.01) and the average onset time(t =22.96,11.96,all P＜0.01)between the test group and two control groups.Moreove,there was also a statistical difference observed in curative rate (x2 = 22.44, P ＜ 0.001) and the average onset time (t = 29.30, P ＜ 0.01) between two control groups.ConclusionIntravenous catheter in combination with UVB radiation was much better than intravenous catheter or UVB radiation only in the treatment of PHN.

Objective To analyze the glucose and metabolism and perinatal outcome in pregnant women with different extent gestational diabetes mellitus (GDM) of IADPSG diagnostic criteria,and to investigate the necessity to manage mild GDM.Methods Total 368 pregnant women at 24-28 gestational weeks were given 75 g glucose oral glucose tolerance test (OGTT).They were divided into three groups according OGTI result,single abnormal group (GDM1 group,148 cases),combination abnormal group (GDM2 group,120 cases) and normal group (100 cases).The three groups were given determinations of glycosylated hemoglobin,fasting C peptide (FCP),fasting insulin (FINS),total cholesterol (TC),triglyceride (TG),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),apolipoprotein (Apo) A1 and ApoB,calculated homeostasis model of assessment for insulin resistance index (HOMA-IR) and homeostasis beta cell index (HBCI).Results From normal group,GDM1 group to GDM2 group,the fasting plasma glucose,glycosylated hemoglobin,FCP,HOMA-IR,TG were gradually increased [(4.39 ± 0.38),(4.98 ± 0.49),(5.25 ± 0.59) mmol/L; (5.10 ± 0.29)％,(5.27 ± 0.36)％,(5.46 ± 0.46)％ ;(1.37 ±0.67),(1.73 ±0.73),(1.99 ±0.96) μ g/L;1.07 ±0.42,1.26 ±0.54,1.37 ±0.43; (2.77 ±0.67),(3.05 ± 0.78),(3.34 ± 0.92) mmol/L,P ＜ 0.01],while HBCI was gradually decreased (5.93 ± 0.48,5.42 ±0.45,5.29 ± 0.44,P ＜ 0.01).ApoA1 in GDM1 group and GDM2 group were significantly lower than that in normal group [(2.21 ±0.39),(2.15 ±0.35) g/L vs.(2.42 ±0.37) g/L,P ＜0.01],but there was no significant difference between GDM1 group and GDM2 group (P＞ 0.05).ApoB/ApoA1 in GDM2 group was significantly higher than that in normal group and GDM1 group (0.49 ±0.14 vs.0.42 ±0.14 and 0.45 ±0.12,P ＜ 0.01),but there was no significant difference between normal group and GDM 1 group (P ＞ 0.05).There was no significant difference in FINS,TC,HDL-C,LDL-C,ApoB,neonatal weight and the incidence rate of premature delivery among the three groups (P ＞ 0.05).The incidence rates of eclampsism,large for date infant and cesarean section in GDM1 group and GDM2 group were significantly higher than those in normal group [8.1％(12/148) and 14.2％(17/120) vs.2.0％(2/100),14.9％(22/148) and 16.7％(20/120)vs.6.0％(6/100),52.0％(77/148) and 54.2％(65/120) vs.30.0％(30/100),P＜ 0.01].Conclusions Different extent GDM of IADPSG diagnostic criteria has different extent abnormal glucose and lipid metabolism and abnormal perinatal outcome,so it is necessary to diagnose and manage GDM pregnant women even mild GDM.

Objective To investigate the relationship between hepatitis B virus (HBV) infection and hepatic metastasis from colorectal cancer.Methods Published literatures and unpublished conference papers from January 1990 to December 2011 were searched in PubMed,Cochrane library,Wanfang Database and CNKI.Data of the literatures were extracted by a table.All the patients with colorectal cancer were divided into the infected group and the control group according to the patients whether infected by HBV or not.The hepatic metastatic rate was analyzed.The Meta analysis was carried out by using the Review Manager 5.0 software,and the heterogeneity between studies was analyzed using the I2.Random effect regression model or fixed effects regression model was used according to the P value.The funnel plot was drawn to assess the potential for publication bias.The count data were presented by odds ratio (OR) and 95％ confidence intervals (95％ CI).Results Fifty-six articles were retrieved,and 11 of which met the criteria.The number of patients with colorectal cancer was 5622,and 924 were in the infected group,4698 in the control group.There was no statistical difference in the heterogeneity between all the articles (I2 =0,df=10,P ＞ 0.05).The hepatic metastatic rate was 10.61％ (98/924) in the infected group,which was significantly lower than 23.84％ (1120/4698) of the control group (OR =0.35,P ＜ 0.05).The funnel plot showed that there was no obvious publication bias in these studies.Conclusion Patients with colorectal cancer and infected by HBV have lower incidence of hepatic metastasis.
