MicroRNA-451 (miR-451) is significantly lowly expressed in glioma,gastric cancer,colorectal cancer,liver cancer and other tumor tissues.Upregulation of miR-451 can significantly inhibit tumor cell proliferation,invasion and metastasis as well as increasing tumor cell apoptosis and improving radiotherapy and chemotherapy sensitivity and other biological effects.

Objective To explore the effect of intensive statin on platelet activity and inflammation factors 24 h after rat myocar‐dial infarction .Methods Seventy Sprague‐Dawley rats were randomly divided into five groups (n= 14):Sham‐operated group (SHAM group);AMI group(control group) ,general group;intensive statin therapy group ;general and intensive statin therapy group;established AMI rat model by ligation of left anterior descending branch of coronary artery .The general group ,general and intensive statin therapy group was fed atorvastatin by 10 mg · kg -1 · d-1 with distilled water 2 mL by intragastric gavage daily for two weeks .The intensive statin therapy group ,general and intensive statin therapy group was fed atorvastatin by 50 mg/kg with distilled water 2 mL by intragastric gavage 12 h before surgery .Serum PAC‐1 ,CD62p ,TNF‐α,hs‐CRP was measured at the time of 24 h of postoperation .Results TNF‐α,hs‐CRP ,PAC‐1 and CD62p levels in control group were significantly higher than the SHAM group and intensive statin group 24 h after the LADS were ligated(P<0 .05);and the factors of intensive statin group were signifi‐cantly lower than that of control group(P<0 .05) .There was no significant difference between the intensive statin group and gener‐al‐intensive group in the concentration of serum TNF ,hs‐CRP and the relative expression of PAC‐1 and CD62p(P> 0 .05);and there was no significant difference between normal group and control group in all the four factors (P>0 .05) .Conclusion Intensive statin therapy before acute myocardial infarction could decrease the level of inflammation factors and inhibit platelet activity postop‐eration .

BACKGROUND: Cell apoptosis and ventricle reconstitution following myocardial infarction are of mutual cause-effect, and they cause vicious cycle. How to reduce the apoptosis events following myocardial infarction is one of keys to saving heart function.OBJECTIVE: To observe the effect of umbilical cord blood mesenchymal stem cell (UCBSMC) transplantation on remaining myocardial tissue of dogs with acute myocardial infarction.DESIGN: A randomized controlled observation.SETTING: Department of Cardiothoracic Surgery, Xinhua Hospital.MATERIALS: This study was carried out in the Central Laboratory of Xinhua Hospital from October 2005 to May 2007.Thirty-six adult hybrid dogs, male and female in half, were provided by the Animal Experimental Center of Xinhua Hospital.METHODS: Thirty-six dogs were divided into cell transplantation group and control group, with 18 dogs in each according to table of random digit. Mesenchymal stem cells were isolated from the umbilical cord blood of full-term pregnant hybrid dogs, cultured and amplified. Then, they were labeled with Laz gene, in vitro induced with 5-azacytidine, and transplanted into the dogs with acute myocardial infarction in the cell transplantation group. Rats in the control group were injected with the same amount of normal saline. Each dog was euthanized by anesthesia for harvesting myocardial specimen 1,4 and 8 weeks after transplantation.MAIN OUTCOME MEASURES: ① Remaining and apoptosis index detected by TUNEL method. ② Myocardial cell volume and histomorphology detected by confocal microscopy. ③ Histological change of myocardial collagen network detected by haematoxylin-basic fuchsin-picric acid staining.RESULTS: Thirty-six involved experimental dogs all entered the stage of final analysis. ①The apoptosis index in the cell transplantation group was significantly lower than that in the control group 1, 4 and 8 weeks after cell transplantation (P ＜0.05). ② Myocardial cell volume in the cell transplantation group 1, 4 and 8 weeks after cell transplantation was significantly larger than that in the control group (P ＜ 0.05). ③ Collagen fiber in the myocardial tissue of dogs in the cell transplantation group was arranged in order and regularly, and in contrast that in the control group was not, and fibers in the control group fused partially.CONCLUSION: UCBSMC transplantation reduces the apoptosis of myocardial cells, promotes the hypertrophy of remaining myocardial cells, regulates myocardial collagen network and improves heart function.

OBJECTIVE: To observe the correlation between traditional Chinese medicine (TCM) syndromes ("deficiency of qi and yin" and "deficiency of liver yin and kidney yin") and A267G in 5'-untranslated region within exonal of megsin gene, and to search the substantial genetic basis for micro-differentiation of TCM syndromes in primary immunoglobulin A nephropathy (IgAN). METHODS: A total of 120 IgAN cases meeting the diagnostic criteria were enrolled. The sequence of single nucleotide polymorphism (SNP) of A267G in 5'-untranslated region within exonal of megsin gene was tested. The correlation between SNP and TCM syndromes was observed. RESULTS: There were 83 cases carrying GG genotype, 34 cases carrying GA genotype and 3 cases carrying AA genotype in 120 cases of primary IgAN. There was a high proportion of "deficiency of liver yin and kidney yin" in IgAN cases with AA and GA genotypes, and a high proportion of "deficiency of qi and yin" in IgAN cases with GG genotype (P<0.01). Odds ratio in TCM syndrome distribution between GG genotype and GA plus AA genotype was 9.800, and 95% confidence interval was 3.969-24.199. The discrepancy also resided in IgAN patients with different genders and ages. CONCLUSION: A267G in 5'-untranslated region within exonal of the megsin gene may be one of the substantial genetic basis for differentiating "deficiency of liver yin and kidney yin" syndrome and "deficiency of qi and yin" syndrome in primary IgAN.

Abundant experiences have already been accumulated in treatment of stroke with acupuncture. Development of rehabilitation theory also brings unprecedented opportunity and challenge to acupuncture. Combined with the modern rehabilitation theory and practice, it is very helpful to deepen the understanding on treatment of acupuncture for cerebral apoplexy and enhance the therapeutic effect in clinic by studying the mechanism of acupuncture treatment, opportunity of intervention, selection of acupoints, needling manipulations and quantity of stimulations etc. Through analysis on the necessity and the way of combination of acupuncture and modern rehabilitation, it is concluded that rehabilitation evaluation, rehabilitation phases and obstacle analysis should be taken as references by acupuncturists to reinforce the therapeutic effect and creditability of acupuncture treatment on cerebral apoplexy.
