Objective To study the proliferation and migration of vascular smooth muscle cell (VSMC) after transferred angiotensin Ⅱ (AngⅡ) type 2 receptor (AT2R) gene. 　Methods The recombinant adenoviral vector, AdCMV-AT2R, containing rat AT2 receptor gene was constructed by homologous recombination, and transfered to rat VSMC in vitro. The expression of AT2R mR NA was detected by RT-PCR. The rate of expression and the change of cell cycle in VSMC were analysed by flow cytometry. These assays including cell devision index. Incorporation of bromodeoxyuridine(BrdU) and 3-(4,5-dimethyl-thiazol-2-yl)2,5-diphenyltetrazolium bromide( MTT) were used to determine the proliferation of VSMC. The modified Boyden's chamber method was used to test the migration of VSMC. The r e-organization of F-actin in VSMC was analysed by confocal microscopy. 　Results RT-PCR showed that the expression of AT2R mRNA increased substantially in transferred VSMC, and the peak value of expression rate is about 89.51% at 48 hours. When the expression of AT2R is at peak value, the ratio of S, G2 and M periods was reduced from 31.7% to 13.9%(P<0.05). The OD values of MTT and BrdU incorporation were reduced by 61.4% and 51.6% respectively(P<0.0(1). the number of VSMC migration was reduced by 62.2%(P<0.05) and the expression of F-actin was also decreased signific antly. 　Conclusion AdCMV-AT2R induced high level expression of AT2 receptor in cultured rat VSMC and its expression can significantly inhibit the proliferation and migration of rats VSMC in vitro.

Objective To compare four PCR genotyping method for Clostridium botulinum,and provide the reliable method for detection and identification of Clostridium botulinum from surveillance and foodborn poisoning in Sichuan Province.Methods Six strains of C.botulinum types A,B and E were used to compare four PCR genotyping method-one muhiplex PCR method was from US FDA,two multiplex PCR method and one real-time PCR method were from ISO,and the differences were preliminarily analyzed.Results Three multiplex PCR method could detect C.botulinum types A,B and E in a single reaction.The expected bands for type A were vague using ISO multiplex PCR method 1,whereas bright expected bands could be obtained in the identification of C.botulinum by the other two multiplex PCR method.Real-time multiplex PCR method could detect different types of C.botulinum simultaneously;however,classification should be carried out separately because fluorescent labels were the same.Conclusion Multiplex PCR method from FDA and multiplex PCR method 2 from ISO were relatively simple and could be recommended for C.botulinum surveillance in Sichuan Province.

Objective To investigate the impacts of mecobalamin on plasma inflammatory factors (plasma high-sensitivity C-reactive protein (Hs-CRP) and carotid artery plaques in patients with H type hypertension.Methods Forty-eight acute ischemic stroke patients who were diagnosed with H type hypertension in the People's Hospital of Taixing were collected,and they were randomly divided them into treatment group and control group,and 24 cases of each group.Patients in both groups were given conventional therapies,including treatment of anti platelet aggregation,plaque stability and reduced plaque treatment.While patients in the treatment group were given additional oral drug of mecobalamin,500 μg each time,three times a day,6 months in all.Each case was evaluated at the second day of hospitalization,four weeks later,eight weeks later,three months and sixth months later.The examination items involved included level of plasma homocysteine(Hcy),level of hsCRP and conditions of carotid artery plaques under ultrasonography.Results Aafter four weeks,eight weeks,three months and sixth months therapy,there were significant differences between treatment group and control group in terms of Hcy (t =4.049,3.896,6.052,6.159 ; P ＜ 0.05) and the level of hs-CRP (t =37.249,28.376,26.454,0.522P ＜ 0.01).Afrter three months and sixth months therapy,compared to the control group,the carotid artery plaques were obviously reduced,and the differences were statistically significant (t =2.309,2.434 ; P ＜ 0.05).Conclusion Mecobalamin can reduce the level of plasma homocysteine,then lead to reductions of levels of plasma inflammatory factors and volume of carotid artery plaques.

Objective To explore the relationship between the expression of thrombospondin-2 (TSP-2), the changes of MVD and angiogenesis in non-small cell lung cancer (NSCLC). Methods By using SP immunohistochemical staining, the expression of TSP-2 and microvessel counting were evaluated in surgically resected specimens from 55 patients with NSCLC and 30 patients' pancancerous tissues, using the anti-TSP-2 and anti-CD34 monoclonal antibodies respectively. Results Active angiogenesis took place in NSCLC tumor tissues. Microvessel density (MVD) was associated with metastasis and clinical stage of NSCLC. Expression level of TSP-2 in the tumor tissues of 55 NSCLC patients was significantly higher than that in the pancancerous tissues from other 30 patients (149.10?2.94 vs. 145.70?4.74, P

Objective To analyze the outcomes of radiotherapy for 74 patients with intracranial ger-minoma. Methods Between 1990 and 2007,74 patients with intracranial germinoma(9 pathologically diag-nosed and 65 clinically diagnosed) were treated with radiotherapy in our hospital. The median age at diagno-sis was 15 (range 5-45) years. Radiation treatment fields varied among patients, including craniospinal irra-diation(CSI), whole brain irradiation, whole ventricular irradiation with primary tumor boost, and involved-field irradiation only to the primary tumor plus margin. The dose was 38.5 -50.0 Gy to the tumor,18-25 Gy to the whole brain/ventricular,and 21-25 Gy to the whole spinal cord in fractions of 1.6-2.0 Gy per day,5 fractions per week. Results The median follow-up time was 80(range 12-168) months and the fol-low-up rate was 97%. Fourteen patients had been followed up for over 10 years. The 1-,5- and 10-year o-verall survival rates were 99% ,96% and 93%. The corresponding disease free survival rates were 97%, 90% and 83%, respectively. Relapses occurred in 9 patients. For the 6 patients with in-field relapse, the dose to the tumor was 38.5-40.0 Gy in 3 patients, 41-45 Gy in 2 and 46-50 Gy in 1. Relapse in the spinal cord was found in 3 patients and none of them received spinal irradiation. Twenty-one patients re-quired hormonal replacement therapy because of radiation induced hypofunction of prehypophysis. Conclu-sions Radiotherapy alone is a curative treatment for intracranial germinoma. The proper dose should be de-termined by tumor numbers and the examination of cerebrospinal fluid.

OBJECTIVE:To investigate clinical efficacy and safety of Teng medicine combined with Gongyankang granules in the treatment of chronic pelvic inflammatory disease(CPID). METHODS:A total of 141 CPID outpatients were selected from our hospital during Jul. 2015-Jun.2016,other patients were divided into control group(65 cases)and observation group(76 cases)ac-cording to random number table. Control group was given Gongyankang granules 9 g orally,bid;observation group additionally re-ceived Teng medicine hot compress on lower abdomen for 30 min until it was cool,once a day,on the basis of control group. Both groups began the medication since third day after the menstrual period,for consecutive 20 d. TCM syndrome,local sign scores and clinical efficacies were compared between 2 groups before and after treatment,and the occurrence of ADR and recur-rence were observed in 2 groups. RESULTS:Before treatment,there was no statistical significance in TCM syndrome scores or lo-cal sign scores between 2 groups (P>0.05). After treatment,TCM syndrome scores and local sign scores of 2 groups were de-creased significantly,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). Clinical total response of observation group were 92.11％,which were significantly higher than 70.77％ of control group, rate recurrence rate of observation group were 2.99％,which were significantly under than 15.79％ of control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Teng medicine hot compress combined with Gongyankang granules show significant efficacy for CPID,can improve TCM syndrome and local sign and reduce recurrence rate with good safety.

Objective To investigate the inhibitory effects of silencing expression ofEZH2 gene on the cell proliferation of human QBC939 cells and its mechanisms. Methods The targeting siRNA was designed and trans-fected into QBC939cells. The expressions of EZH2 mRNA and protein were detected by real-time qPCR and west-ern blotting,respectively. The ability of cellproliferationwas analyzed by MTT assay and plate clone formation assay. Cell apoptosis and cycle percentage weremeasured by flow cytometry. Cell senescence was assessed byβ-galactosi-dase dyeing.The expressions of H3K27me3,P14ARF,P16INK4a,P53,P21 and E2F1 proteinwere determined by West-ern blotting.Results Compared with the control group ,the expressions of mRNAand protein were significantly elevat-ed in experimental group. The ability of cellproliferation in the experiment group was significantly down regulated , which could also cause a rise of G1/S phase ,but not a marked variation of apoptosis rate. Silencing EZH2 would induce a obvious senescence phenotype in QBC939 cells. EZH2-siRNA transferredcould also down-regulate the expressions of H3K27me3 and E2F1 protein,while up-regulating the expressions of P14ARF,P16INK4a,P53 and P21 protein in QBC939 cells.Conclusions Silencing EZH2 could induce a significant inhibition on cell proliferation of QBC939 cells,the mechanism of which may be associated with the senescence pathway regulation.
