Objective To evaluate the clinical effectiveness of combined use of traditional Chinese and Western medicine for chronic pelvic inflammatory diseases.Methods By searching in the major databases of CNKI,ISI Web of Knowledge,VIP Information and Pubmed,we collected data of randomized controlled trials pertaining to combined use of traditional Chinese and Western medicine in the treatment of chronic pelvic inflammatory diseases.Results Twenty-five randomized controlled trials involving totally 3081 patients were collected according to the inclusion criteria,and meta-analysis of the data indicated that combined use of traditional Chinese and Western medicine can be of great value in the management of chronic pelvic inflammatory diseases in comparison with exclusive use of Western medicine [combined odds ratio(OR)was 3.20 with 95% confidence interval(CI)(2.74,3.73),Z=14.85,P＜0.01].Conclusion The clinical evidence derived from the analysis suggests that the combination of traditional Chinese and Western medicine for chronic pelvic inflammatory diseases can be effective with good security.

We studied the function of connexin 43 (Cx43) gene in Xiao Meishan swine bone marrow mesenchymal stem cells (BMSCs) resulting from overexpression. Cx43 eukaryotic expression vector (pEGFP-Cx43) was constructed and transfected into BMSCs by nucleofector, after detecting the transfection efficiency; the expression of Cx43 was verified by RT-PCR, immunofluorescence and western blotting. Furthermore, we detected its cell cycle and apoptosis through flow cytometry. Our results show that pEGFP-Cx43 plasmid was successfully constructed, and green fluorescence in pEGFP-Cx43 transfected BMSCs was highly expressed with 60% transfection efficiency. In transgenic Xiao Meishan swines BMSCs, the expression level of Cx43 mRNA and protein were up-regulated. Meanwhile, the ability of cell proliferation was significantly increased, and the apoptosis rate was significantly reduced. Taken together, Cx43 overexpression could promote the proliferation of Xiao Meishan swine's BMSCs and markedly reduce their apoptosis, which provides evidence for in vivo research.

Produced by bone cells and stored in the matrix.bone ceil growth factor can contribute to the regulation of bone growth.Gene regulation has its role in bone development.Many factors of this kind have been founded recently.They play their role during the bone formation and absorption processes in the way of autocrine and paracrine.The genes of core binding factor α_1(Cbfα_1)and estrogen receptor α(Erα)have been the recent years'hot factors that are related to the bone development,Gene polymorphism refers to variation on gene level which often occurs in the non-coding domain or the domain bearing no important regulatory function in gene order.This article reviewed the research status of the relation between Cbfα_1 and Erα gene polymorphism with bone development.

Objective To analyze the CT and MRI performances of chromophobe cell renal carcinoma,to improve the understanding of the disease.Methods The CT and MRI performances of 16 patients with chromophobe cell renal carcinoma confirmed by post-operation pathology were analyzed retrospectively.Results Among 13 cases examined by CT,8 cases had homogeneous lesion including the homogeneous lesions density of 5 cases higher than that of normal renal parenchyma,and the other 5 cases had inhomogeneous density.After enhanced scan,the uneven essence ingredients were markedly enhanced in homogeneous density and inhomogeneous density cases,and the enhancement degree in arterial phase was lower than that of the renal cortex and higher than that of the renal medulla.Among 8 cases checked by MRI,2 cases had signal homogeneity with long T1 weighted imaging and long T2 weighted imaging signal,of which 5 cases appeared high signal in T1 weighted imaging flat lesions.The enhancement mode were similar with CT.In 5 patients examined by CT and MRI at the same time,their density,signal and the pattern strengthening were similar.Conclusions Chromophobe cell renal carcinoma is a rare malignant renal cell carcinoma,and CT and MRI can reflect the composition and hemodynamic changes.When homogeneity and high density or T1WI appeared high signal,disease was large and necrosis was less,and strengthening belt was appeared in lesions,it is value on diagnosis of chromophobe cell renal carcinoma.

BACKGROUND:Studies on high glucose exposure in human periodontal ligament cel s usual y focus on the biological behaviors, pathways and secretory factors, but whether the metabolic memory is involved is little known. OBJECTIVE:To investigate the metabolic memory of high glucose exposure in human periodontal ligament cel s. METHODS:Human periodontal ligament cel s were primarily cultured and identified. Cel s at 5-8 passages were selected and randomized into four groups. Group A (controls):DMEM containing 5.5 mmol/L glucose for 8 days;group B (5-day memory group):DMEM containing 35 mmol/L glucose for 3 days and DMEM containing 5.5 mmol/L glucose for 5 days;group C (3-day memory group):DMEM containing 35 mmol/L glucose for 5 days and DMEM containing 5.5 mmol/L glucose for 3 days;group D (8-day high glucose group):DMEM containing 35 mmol/L glucose for 8 days. The cel proliferation was detected by cel counting kit-8, the cel apoptosis was determined by flow cytometry, and the levels of total proteins and alkaline phosphatase were investigated using ELISA. RESULTS AND CONCLUSION:Compared with the control group, the cel proliferation in the other three groups was significantly reduced (P<0.05), the number of apoptotic cel s was significantly increased, while the levels of total proteins and alkaline phosphatase were significantly decreased (P<0.05). These results suggest that high glucose causes persistent changes in human periodontal ligament cel s by inhibiting cel viability, increasing the apoptosis and downregulating the levels of the total proteins and alkaline phosphatase

Objectives To compare the effect of one-stage revision and two-stage revision for the treatment of culture-negative peripros-thetic joint infection after total hip arthroplasty.Methods A retrospective study was conducted with the clinical data of 41 patients who had chronic periprosthetic joint infection after total hip arthroplasty and then underwent one or two-stage revision surgery from February 2006 to February 2014.The patients were divided into two groups according to different surgical way,namely the 16 patients who received the one-stage revision surgery were regarded as the OSR group,and the other 25 cases who underwent the two-stage revision surgery were regarded as the TSR group.The clinical efficacy of the two surgical way were assessed with Harris Hip score,visual analogue scale (VAS),and rate of infection clearance.Results The average duration of follow up was 29.7 months (9 to 48 months).At the last follow-up,Harris Hip score of TSR group was higher than that of the OSR group,and the difference was statistically significant (P =0.04),and the VAS score of TSR group was lower than that of the OSR group with statistical differences (P =0.02).Additionally,the rate of infection clearance in TSR group was significantly higher than OSR group (P =0.04).Conclusion Culture-negative periprosthetic joint infection can be effectively controled by one or two-stage revision surgery.However,patients got a better prognosis after two-stage revision surgery.

Objective To observe the effects of intra-articular ozone injection on the secretion of tumor necrosis factor (TNF)-α,Interleukin (IL)-6,IL-17A,and vascular endothelial growth factor (VEGF) in the serum of rats with collagen-induced arthritis (CIA) and explore the therapeutic mechanism of ozone in RA treatment.Methods Thrity-two Wistar rats were randomized into 4 groups,including the ozone groups that receivedintra-articularinjection of 40 μg/ml ozone (O3 group),a blank control group (normal group),a methotrexate (MTX) group (MTX group) anda collagen-induced arthritismodel (CIA group).All the rats,except for those in the blank control group,were subjected to hypodermic injection of bovine collagen Ⅱ and complete Freund's adjuvant to induce CIA.Ozone treatment was administered once weekly for 3 weeks starting at 14 days after the model were established.MTX group were treated with methotrexate 0.9 mg/kg,once a week,a total of three weeks.The swelling degree of the foot were observed,and the serum contents of TNF-oα,IL-6,IL-17A and VEGF were detected.One-way analysis of variance or Kruskal-Wallis test was used to evaluate the experimental data.Results At the end of treatment,the degree of foot swelling was reduced significantly in rats with O3 group compared with that in the CIA group [(4.21±0.14) ml vs (9.12±0.17) ml,t=8.43,P=0.023].The serum concentration of TNF-α,IL-6 and VEGF showed significant difference between the CIA group and the O3 group[91.55(86.55,98.53) pg/ml vs 14.45 (12.55,16.15) pg/ml,x2=6.216,P=0.002;145.08(37.44± 362.82) pg/ml vs 5.84(5.47,15.93) pg/ml,x2=13.136,P=0.004;51.56(46.09,74.10) pg/ml vs.36.22(32.18,41.69) pg/ml,x2=3.732,P=0.002].There was no statistically significant difference between the O3 group and MTX group [14.45(12.55,16.15) pg/ml vs [12.45(11.80,15.60) pg/ml,x2=0.243,P＞0.05;5.84(5.47,15.93) pg/ml vs 7.86(5.25,15.23) pg/ml,x2=0.058,P＞0.05;36.22(32.18±41.69) pg/ml vs 40.17(35.47,50.73) pg/ml,x2=0.516,P＞0.05].The serum concentration of IL-17A showed no significant difference between the normal group,the CIAgroup,the MTX group and the O3 group (F=1.827,P=0.165).Conclusion Intra-articular injecfion of 40 μg/ml ozone can attenuate synovitis in rats with CIA,the mechanism may relate to the inhibition of TNF-oα,IL-6 and VEGF in the serum.

Objective To investigate the association of interleukin-6 (IL-6) with depression using meta analysis. Methods A systematic literature search was conducted to examine depression and interleukin-6 in Chinese patients us-ing“depression”and“interleukin-6”in Databases including PubMed, CBM, VIP, CNKI and WanFang Data. A me-ta-analysis was performed to analyze correlation between depression and interleukin-6 using RevMan 5.2.8 software. Results A total of 9 studies were recruited, involving 432 depression patients and 277 healthy controls. The results of meta-analysis showed that concentration of IL-6 was higher in depression patients than in healthy controls(SMD=1.48, 95%CI:0.78~2.18,P<0.05). Subgroup analysis in the first-episode subgroup and the non first-episode subgroup showed that concentration of interleukin-6 was higher in depression patients than that in controls [the first-episode subgroup (SMD=1.94,95%CI:0.07~3.81,P<0.05), the non first-episode subgroup (SMD=1.26,95%CI:0.60~1.93,P<0.05)]. Conclusion There is a good correlation between depression and the serum IL-6 concentration. Due to the small number of studies and heterogeneity in different studies, the present meta-analysis has not yet confirmed the quantitative correla-tion between IL-6 and depression.
