Purpose:To study the expression of telomerase,p53 and p16 genes in non small cell lung cancer(NSCLC). Methods:The expression of telomerase, p53 and p16 genes were examined in 40 NSCLC cases by SP and TRAP methods, respectively. Results:The positive expression rates of telomerase,p53 and p16 genes in NSCLC were 92.5%, 37.5% and 66.7%, respectively. The positive expression rate of p53 gene correlated closely with the T and pathological staging of NSCLC ( P 0.05). Telomerase activity was correlated with the expression rate of p53 gene and pathological stages but negatively correlated with the ages of NSCLC patients( P

Objective To investigate the effect of atorvastatin on the expressions of solubility P-selectin(sP-selectin) and high sensitive C reactive protein(hs-CRP) in patients with percutaneous coronary intervention (PCI),and to explore the protective effect of atorvastatin on myocardium.Methods A total of 100 acute coronary syndrome patients having underwent successful PCI were enrolled in this study.All patients were divided into 3 groups by random digits table method:standard treatment group (group A,30 patients,atorvastatin 20 mg),low-dose atorvastatin pretreatment group (group B,35 patients,preoperative 12 h and 2 h atorvastatin 40 mg and 20 mg,respectively) and high-dose atorvastatin pretreatment group (group C,35 patients,preoperative 12 h and 2 h atorvastatin 80 mg and 40 mg,respectively).The level of sP-selectin was measured with ELISA.The level of hs-CRP was measured with latex enhanced immunoturbidimetry.Results Before operation,the levels of sP-selectin in group A,B,C were (2.32 ±0.40),(2.51 ± 0.33),(2.47 ± 0.28) μ g/L.After 6 and 12 h of operation,the levels of sP-selectin in group A,B,C were (4.12 ± 0.75),(3.34 ± 0.42),(3.31 ± 0.46) μ g/L and (5.64 ± 1.07),(4.08 ± 0.74),(3.84 ±0.48) μg/L.The levels of sP-selectin in group A,B,C after operation were significantly higher than that before operation (P ＜ 0.05).At the same time point,the levels of sP-selectin in group B,C after operation were significantly lower than that in group A (P＜ 0.05).Before operation,the levels of hs-CRP in group A,B,C were (4.32 ±0.51),(4.46 ±0.57),(4.29 ±0.43) mg/L,after 6 and 12 h of operation,the levels of hs-CRP in group A,B,C were (8.91 ± 1.34),(7.44 ± 1.06),(7.28 ±0.95) mg/L and (13.66 ± 1.49),(8.08 ± 1.14),(7.92 ± 1.04) mg/L.The levels of hs-CRP in group A,B,C after operation were significantly higher than that before operation (P＜ 0.05).At the same time point,the levels of hs-CRP in group B,C after operation were significantly lower than that in group A (P ＜ 0.05).The analysis of Pearson correlation showed,the level of sP-selectin was positively related with hs-CRP (r =0.753,P ＜0.01).The incidence of perioperative myocardial infarction was 23.3％ (7/30),5.7％ (2/35) and 2.9％ (1/35) in group A,B and C,respectively.The incidence in group A was significantly higher than that in group B and C (P ＜ 0.05).But there was no significant difference between group B and group C (P＞ 0.05).Conclusion The atorvastatin pretreatment can decrease the levels of sP-selectin and hs-CRP in patients after PCI,which play an important role in myocardium protection.

Objective To study the effect and value of hepatoarterical catheter chemotherapy in treating gastric carcinoma with liver metastasis. Methods A total of 31 cases of gastric carcinoma with liver metastasis undergoing radical operation were preoperatively randomly divided into 2 groups: Regional infusion chemotherapy (treatment group, 17 cases) and peripheral venous chemotherapy (control group, 14 cases). Results The short-term effectiveness of the treatment group was 88.3 %(15/17). The survival rates of 1, 2, 3 year were 88.2 %, 62.7 %, 28.9 %, respectively. However, the short-term effectiveness of the control group was 28.6 %(4/14). The survival rates of 1, 2, 3 year were 68.1 %, 38.9 %, 13.0 %, respectively. There was obvious difference between the two groups (χ~2 = 12.87, P <0.05;χ~2 =5.511, P<0.01). Conclusion Hepatoarterical catheter chemotherapy is effective for gastric carcinoma with liver metastasis undergoing radical operation and has less toxic side effects.

ObjectiveTo observe effect of estradiol on respiratory of ovariectomized rats.Methods30 adult female rats were randomly divided into ovariectomy group (group A), estradiol group (group B) and sham ovariectomy group (group C). Rats of group B were injected with 17-β estradiol (20μg/kg/d), that of group A and group C were injected only with normal saline (0.1ml/d). After 6 weeks, effect of estradiol on respiratory of ovariectomized rats was assessed with testing level of rats' serum estradiol and discharge frequency and integrated amplitude of phrenic nerve. ResultsThe level of serum estradiol of group A was significantly decreased compared with group B and group C (P<0.01). Discharge frequency and integrated amplitude of phrenic nerve of group A were decreased compared with group B and group C (P<0.05).ConclusionEstradiol can excite respiratory responses in ovariectomized rats.

Objective To establish and evaluate 3 kinds of minimally-invasive valve implantation model in vivo.Methods A novel tissue engineered heart valve(TEHV) manufactured by branched polyethylene glycol cross-linked acellular porcine valve and a minimally-invasive valve implantation system according to the design of Corevalve revalving system were adopted.After anesthesia,18 adult male goats were randomly divided into 3 groups: the ulrasound-directed orthotropic group (group A,n =6),angiography-directed orthotropic group (group B,n =6) and direct-released heterotopic group (group C,n =6),and all received minimally-invasive valve implantation orthotropically or heterotopically.4 weeks later,the valvular function was evaluated by CTA and/or echocardiography.Results All 3 kinds of caprine model were successfully constructed.The operation success rate of each group was A: 66.7％,B: 50.0％ and C: 100.0％,respectively(multiple x2 analysis,group A and B P ＞0.05; group A and C,group B and C,P ＜0.05).The operation-time of each group was A: (79 ± 18) min,B:(61 ±23) min,C: (45 ± 15) min(one-way ANOVA,P ＜0.05).The survival rate at4 weeks was A: 100％,B: 100％ and C: 83.3％ (multiple x2 analysis,P ＞ 0.05).Echocardiography and CTA proved the short-term function of implanted TEHV was satisfactory.Conclusion All 3 kinds of caprine valve implantation model can be established without cardiopulmonary bypass and blood transfusion.The devices and equipments required in group A is relatively simple,but the procedure cost longer time for it is hard to determine the right position by ultrasound.The application of angiography made the positioning much easier in group B while the procedure had to be performed in specific operation room with angiographic apparatus.Group C did rely on neither special equipments nor complex operation,but the valve leaflets cannot work normally,so this model was only suitable for testing in vivo characteristics such as biocompatiblities.

Objective To investigate the protective effect of sirolimus pretreatment against liver ischemia-reperfusion(I/R)injury in rat model and the possible mechanism.Methods Forty-eight male SD rats were randomized into four groups (12/group):A:sham group with saline,B:sham group with sirolimus,C:saline-operated group,D:sirolimus-operated group.The rats were pretreated with either saline or sirolimus (2 mg·kg~(-1)·d~(-1))by oral gavage for two weeks．The rat partial liver model of I/R injury was established,and the samples were collected at the 24th h after the I/R The serum ALT and AST levels were determined,the histologic changes were observed by HE staining under the light microscopy,the frequency of CD4~+ CD25~+ T cells among mononuclear cells in liver tissue was analyzed by using flow cytometry,the expression of Foxp3 mRNA was detected in liver tissue by real-time PCR,and the serum TGF-β,IL-10 levels were measured by enzyme-linked immunosorbent assay (ELISA).Results Serum ALT and AST levels were significantly decreased and the histological damage was significantly alleviated in the sirolimus-operated group as compared with saline-operated group(P<0.05).The percentage of CD4~+ CD25~+ T cells among mononuclear cells in groups A,B,C,and D was(6.12±1.87)%,(22.36±6.75)%,(4.53±1.02)% and(13.29±3.16)% respectively in liver tissue The expression levels of the Foxp3 mRNA were significantly higher in sirolimus group than in saline group(P<0.05).The ELISA showed that sirolimus could significantly increase the levels of TGF-β and IL-H)(P<0.05).Conclusion Pretreatment of sirolimus can effectively protect against liver ischemia-reperfusion injury in rats,which may be related to induction of CD4~+ CD25~+ Foxp3~+ T regulator cells by sirolimus,and the increase of TGF-β and IL-10 secretion to inhibit the imflammatory response.

Forest musk deer (Moschus berezovskii), a rare wild medicinal animal, is listed under the category of the state key protected wildlife list of China. Musk, secreted by the musk glands, is with high economic and medicinal value and used as precious traditional medicine in China. In order to meet the needs of musk in Chinese traditional medicine, forest musk deer farming was conducted in 1950s, but the research progress on musk secretion mechanism was slow. Therefore, by reviewing the histological and anatomical structure of forest musk deer musk gland, the relationship between sex hormones and the musk secretion process, and the molecular mechanism of the musk secretion, the existing problems in investigating the musk secretion mechanism were analyzed and the development trends in this field were also discussed, in order to provide a reference for further studies on the musk secretion mechanism and improve musk production of forest musk deer.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.

METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.

RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.

CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.
