Objective To investigate the role of anti apoptosis gene bcl 2 in the survival of cultured uveal melanoma UM cells. Methods Antisense oligodeoxynucleotides (AS ODN) bcl 2 were delivered with cationic lipid to primary cultured UM cells. The inhibitory effect of AS ODN bcl 2 on proliferation of UM cells was examined by 3, 4,5 Dimethyliazol 2,5 diphenyl tetrazolium bromide (MTT) method. Using DNA ladder to determine if the UM cells had been apoptotic. Bcl 2 expression was detected by RT PCR and Westernblot technics. Results The effect of AS ODN bcl 2 in inhibiting the proliferation of cultured UM cells had opposite relation to dosage. It down regulated the mRNA and protein level of bcl 2 gene, and the sense ODN didn′t have this effect. Conclusion AS ODN bcl 2 can down regulate bcl 2 expression, inhibits UM cells proliferation and induces apoptosis.

Objective To systematically evaluate the clinical efficacy and safety of Fufang-Danshen Injection (FD) in the treatment of unstable angina pectoris(UAP). Methods Randomized controlled trials (RCTs) and quasi-RCTs regarding FD in the treatment of UAP were collected through comprehensive searches of China National Knowledge Infrastructure(CNKI), Chinese Scientific Journals Database(VIP), Wan fang Database, Chinese Biomedical Literature Database(CBM), PubMed, Embase and Cochrane Library from January 1979 to December 2013. Two reviewers independently assessed the quality of the included studies by the Cochrane risk of bias, and extracted the information from the included studies. Meta-analysis was conducted with the software Review Manager 5.2. Results A total of 13 studies with 1156 participants were included. In the meta-analysis, ①the total effective rate of UAP:in term of FD+conventional therapy with western medicine(WM)vsWM, the difference between two groups was statistically significant [RR=1.32, 95%CI(1.21, 1.43), P<0.01]; FD+low molecular weight heparin+WM vs WM, difference between two groups was also statistically significant [RR=1.29, 95% CI(1.17, 1.42), P<0.01], which indicated that the efficacy of experimental group was higher than the control group. Other interventions, such as FD+WM vs low molecular weight heparin+WM and FD vs WM, there was no significant difference between two groups. ②the total effective rate of ECG:in term of FD+WM vs WM, the difference between two groups was statistically significant [RR=1.34, 95%CI (1.14, 1.57), P<0.01]; in term of FD vs WM, difference between two groups was statistically significant [RR=1.49, 95%CI(1.13, 1.96), P<0.01], which indicated that experimental group can effectively improve the total effective rate of ECG. ③ frequency of angina attacks:in term of FD+WM vs WM, the difference between two groups was statistically significant [MD=1.07, 95%CI(0.48, 1.66), P<0.01]. No differences between groups existed in other analysis. ④ adverse drug reactions(ADRs):4 articles cleared that there was no ADRs in the studies, 4 studies reported ADRs, which represented headache, nausea, flushing and so on. There were 9 cases in the experimental group, and 9 in control group. Conclusion Based on the meta-analysis, FD was effective and relatively safe for the treatment of UAP in clinical. However, since the articles enrolled in the study were not in high quality, more qualified studies should be conducted for the further assessment of efficacy and safety of FD for UAP.

Objective To systematically evaluate the clinical efficacy and safety of Danshen Chuanxiongqin Injection (DCI) in the treatment of angina pectoris. Methods Randomized controlled trials (RCTs) regarding DCI in the treatment of angina pectoris were searched in CNKI, VIP, Wanfang Database, CBM, PubMed, Embase and Cochrane Library by Feb. 2014. Two researchers independently retrieved the RCTs and extracted the information. The Cochrane risk of bias method was used to assess the quality of the included studies, and a meta-analysis was conducted with Review Manager 5.2 software. Results A total of 12 RCTs with 1145 participants were included. The meta-analysis indicated that the combined use of DCI and conventional treatment with western medicine was more effective in the outcomes of the total clinical effective rate [RR=1.27, 95%CI (1.19,1.35), P<0.000 01], the total effective rate of ECG [RR=1.34, 95%CI (1.23,1.46), P<0.000 01], and decrease of plasma viscosity [MD=-0.15, 95%CI (-0.25,-0.05), P=0.004] and fibrinogen [MD=-0.96, 95%CI (-1.14,-0.78), P<0.000 01]. And there were no adverse drug reaction reports. Conclusion Based on this systematic evaluation, DCI combined with conventional therapy is effective and relatively safe in treating angina pectoris, but it still needs larger samples, multi-center, and high quality RCT to verify.

BACKGROUND:Impaired balance between osteogenesis and adipogenesis of bone marrow mesenchymal stem cels is a crucial pathological mechanism of osteoporosis. Mechanical loads applied to bone tissue can increase bone formation and improve bone strength, and meanwhile lead to the release of extracelular nucleotides, such as adenosine triphosphate.
OBJECTIVE: To determine the effects of adenosine triphosphate on the osteogenic and adipogenic differentiation of bone marrow mesenchymal stem cels and to investigate the underlying mechanisms.
METHODS:The effect of adenosine triphosphate (10, 50, 250 μmol/L) on differentiation of bone marrow mesenchymal stem cels were measured by osteogenic and adipogenic related genes expression, alizarin red staining and oil red O staining. The activation of ERK1/2 signaling pathway by adenosine triphosphate was tested using western blot assay.
RESULTS AND CONCLUSION: Incubation of bone marrow mesenchymal stem cels with adenosine triphosphate resulted in the dose-dependent increase of osteogenic genes expression and calcium deposition, and inhibition of adipogenic genes expression and lipid droplet formation, but had no effects on cel proliferation. Adenosine triphosphate activated ERK1/2 signaling pathway, and U0126 as an ERK1/2 inhibitor restrained the effect of adenosine triphosphate on the differentiation of bone marrow mesenchymal stem cels.

Objective To investigate the association between single nucleotide polymorphisms (SNP) rs 653765 and rs514049 inADAM10gene and clinical characteristics in asthma in Han Chinese children. MethodsA case-control study was performed in that research, and 221 children with asthma were recruited and an other 236 normal children were recruited as controls. The genotypes of two SNPs in ADAM 10 gene were detected using PCR-RFLP. And all data were analyzed by SPSS 19 . 0 . Results In case-controlled study, we found the frequency of TT genotype in case group was higher than that of controlgroup (P=0 . 028 ), and the frequency of T allele was higher than that of control group (P=0 . 008 ). The genotypes and alleles of rs 514049 was not associated with asthma (P=0 . 604 , 0 . 356 ).There were no difference in serum ADAM 10 levels between asthma and control group (P=0 . 238 ), but in asthma group we found patients with TT genotype may have a higher level ADAM 10 than the one with CC genotype (P=0 . 034 ). The polymorphism of rs 653765 was not associated with the level of C-reaction protein, the number of LYM, IgE and EOS% (P>0 . 05 ). Conclusions The genotype of rs 653765 in ADAM 10 gene was associated with asthma in the central of China, and T allele was a risk factor. The polymorphism of rs 653765 might be associated with the levels of ADAM 10 .

Background and purpose: About 20 cases of BML have been reported in the literature,they occurred in females with history of uterus leiomyoma.BML appears as a histopathologic benign smooth muscle tumor located far from the uterus,often in the lungs.Firstly,it should be confirmed as originating from smooth muscle by immunohistochemistry,Secondly,its primary tumor should be confirmed as benign,with mucoid degenenation,it also should be distinguished from myxoid leiomyosacroma.Methods:We report a case of benign metastasizing leiomyoma,study its clinical,histopathologic and immunohistologic features,discuss the diagnosis and differential diagnosis and give a review of the related references.Results:The case occurred in a forty-two year old female who was found to have bilateral lung nodules after hysterectomy of her uterus leiomyoma six years ago.An open lung biopsy revealed the nodules to consist of proliferating smooth muscle cells with a histopathologic feature similar to her uterus leimyoma,consistent with the diagnosis of BML.Positive staining of estrogen and progesterone receptors was detected in both the uterus leiomyoma and the metastasizing lesions.No significant increase or enlargement of the lung nodules were found seven months after the operation with no therapy except taking Chinese traditional medicine.Conclusions:BML is a rare entity usually occurring in females with history of uterus leiomyoma.It appears as a histopathologic benign smooth muscle tumors distant from the uterus.It is hormone dependent and progresses slowly.

OBJECTIVETo explore the effects of warm needling combined with Zhangmo decoction (see text) on endometrial receptivity in patients with clomiphene (CC)-induced ovulation.

METHODSOne hundred and sixty cases were randomly divided into a CC group (group A), a CC+ progynova group (group B), a CC+ Zhangmo decoction group (group C) and a CC+ Zhangmo decoction + warm needling group (group D), 40 cases in each one. In the Group A, CC alone was applied. In the group B, progynova was jointly used on the 8th day of menstrual cycle. In the Group C, Zhangmo decoction was jointly used on the 5th day of menstrual cycle. In the group D, based on treatment of the Zhangmo decoction, warm needling was applied at Guanyuan (CV 4), Zhongji (CV 3) and Zigong (EX-CA 1) etc. The endometrial thickness and type, pulsatility index (PI), resistance index (RI), ratio of S/D on day of human chorionic gonadotropin (HCG) and pregnancy rate were observed in fou groups.

RESULTSThe PI, RI and S/D in the group C and D were obviously lower than those in group A and B (all P < 0.01). The endometrial thickness was (7.7 +/- 1.49) mm in group B, (8.2 +/- 1.54) mm in group C and (8.9 +/- 1.51) mm in group D, which were significantly different from (6.4 5 +/- 1.26) mm in the group A (all P < 0.01) also there was a significant difference between group C and D (P < 0.05). The rate of endometrial type A was 65.0% in the group D, which was significantly higer than 27.5% in the group A, 32.5% in the group B and 35.0% in the group C (all P < 0.01). The pregnancy rate was 30.0% in the group D, which was obviously higher than 12.5% in the group A, 15.0% in the group B and 17.5% in the group C (P < 0.05). The endometrial thickness and rate of endometrial type A in the pregnant were obviously higher than those in the non-pregnant (both P < 0.01) while PI, RI and S/D was lower than those in the non-pregnant (P < 0.01, P < 0.05).

CONCLUSIONWarm needing combined with Zhangmo decoction could improve endometrial thickness, morphology and uterine spiral artery to improve pregnancy rate, which has superior effect to clomiphene, clomiphene combined with progynova and clomiphene combined with Zhangmo decoction.
