Objective To investigate the inhibitory effects of Snail—— a zinc finger transcription factor, anti-sense plasmid on the invasion of ovary carcinoma cell lines in vitro. Methods Four human ovarian carcinoma cell lines ES-2,OVCAR3,HO8910,HO8910PM were analyzed for the expression of Snail and E-cadherin mRNA by RT-PCR.Then anti-Snail plasmid transfection was introduced into HO8910 cells using lipofectin 2000 reagent to investigate the inverse correlation between E-cadherin and Snail expression, and the inhibitory effects of anti-sense Snail were also detected by Transwell motility assay and Matrigel invasion assay. Results The results demonstrated the presence of Snail mRNA in ES-2,HO8910,HO8910PM detected by RT-PCR. By contrast, E-cadherin mRNA was only detected in OVCAR3 by RT-PCR.The inverse relationships were further observed by transient transfection of anti-sense Snail into HO8910 cells, which showed the down-regulated expression of Snail and the re-expression of E-cadherin. The Snail mRNA levels were 0.897?0.005,0.865?0.010,0.338?0.014 after 0,24,48 h of transfection and that of E-cadherin were 0,0.130?0.001,0.217?0.005 respectively, the difference was significant between different time points (P

Objective To investigate the influence of rosuvastatin on inflammatory factors and immune func-tion in chronic obstructive pulmonary disease(COPD)with pulmonary heart disease.Methods 80 COPD patients with pulmonary heart disease were randomly divided into two groups,40 cases in each group.The control group was treated with conventional medicine comprehensive treatment,the observation group was given rosuvastatin based on the control group.The inflammatory cytokines (TNF -α,IL -1 and hs -CRP)changes,immunoglobulin IgM,IgG and IgA changes situation,and heart,lung function changes related indicators were compared between the two groups before and after the treatment.Results After treatment,the TNF -α,IL -1 and hs CRP levels of the observation group were significantly lower than those before treatment(t =145.5,35.35,57.5,all P <0.05)and those of the control group(t =160.75,11.45,32.99,all P <0.05).After treatment,the IgM,IgG and IgA levels of the observa-tion group were significantly lower than those before treatment (t =4.89 of 18.29,3.42,all P <0.05)and those of the control group (t =2.55 9.67,2.342,all P <0.05 ).After treatment,the FEV1 ,FEV1 /FVC and LVEF of the observation group were significantly higher than those before treatment(t =40.44 33.64,33.79,all P <0.05),while the PAP level was significantly lower than that before treatment (t =24.12,P <0.05),and the FEV1 ,FEV1 /FVC and LVEF of the observation group were significantly higher than those of the control group after treatment(t =16.30, 15.82,18.72,all P <0.05),while the PAP level was significantly lower than that of the control group after treatment (t =13.43,P <0.05).Conclusion Combined rosuvastatin therapy for COPD patients with pulmonary heart disease can effectively reduce body inflammatory response,improve immune function and myocardial contractility,so it can promote functional recovery of heart and lung in patients.

ObjectiveTo investigate feasibility of use of glucose injection instead of glucose powder in oral glucose tolerance test (OGTT). MethodsSixty healthy adult volunteers without history of diabetes were recruited for a standard OGTT with 75 g anhydrous glucose powder first. One week later, they were randomly divided into two groups, each of the one group (30 volunteers) orally took seven ampoules (20 ml/ampoule) and each of the other group (30 volunteer) took 7.5 ampoules of 50％ glucose injection for OGTT again, as compared to those with standard OGTT.Plasma levels of glucose and insulin were examined to evaluate whether different forms and dosage of glucose had similar results in OGTT. ResultsIn 23 volunteers with normal glucose tolerance, their plasma levels of glucose were ( 4. 8 ± 0. 4 ), ( 6. 7 ±0. 6), (5.9 ±0. 8), (5.5 ±0. 9) and (4. 8 ±0. 9) mmol/L at 0, 30, 60, 120 and 180 min after oral load with 75 g anhydrous glucose powder, respectively.

Twenty-two cases of high serum level of insulin were found from 60 volunteers with standard OGTT, with their logarithmic transformation of serum insulin of 2.2±0.6, 4.7 ±0.5, 4.9±0.7, 4.2 t 1.0 and 2. 8 ±0.9 at0, 30, 60, 120 and 180 min after oral load with 75 g anhydrous glucose powder, respectively; 10 of 22 volunteers were found with high serum insulin level of its logarithmic transformation of 2. 4 ± 0. 6, 4. 7 ± 0. 5, 4. 7 ± 0. 3, 4. 1 ± 0. 8 and 2. 8 ± 1.1 at 0,30, 60, 120 and 180 min after oral load with seven ampoules of 50％ glucose injection, respectively ; and 12 of 22 volunteers were found with high serum insulin level of its logarithmic transformation of 1.9 ± 0. 5,4. 5 ± 0. 6, 4. 6 ± 0. 6, 3. 7 ± 1.0 and 2. 4 ± 0. 9 at 0, 30, 60, 120 and 180 min after oral load with 7. 5ampoules of 50％ glucose injection, respectively; with no significant difference between varied methods.There also was no statistically significant difference in occurrence of adverse effects between these three OGTT methods. ConclusionsEither seven or 7. 5 ampoules of 50％ glucose injection can substitute 75 g anhydrous glucose powder in OGTT, with similar test results and safety.

Objective To supply anatomic foundation for TRAM and DIEP flaps breast reconstruction with both sensory innervation and rectus abdominis muscle function preserved. Methods Dissections of T8～T12 nerves in anterior abdominal wall were performed on 9 embalmed female cadavers (18 sides). By reconstructing DIEP flaps in 15 cases, the natures of the intercostal nerves and the relations with deep inferior epigastric perforators were investigated. Results Most intercostal nerves pierced the rectus abdominis muscle in the lateral one third. There were interconnections between muscular branches of segmental nerves. Sensory branches traveling with vascular perforators were divided into medial branch and lateral branch. The mean length of pure sensory nerve was (27.6?12.2)mm. Conclusion It is possible to preserve sensory innervation by coapting lower intercostal nerves to the 4th thoracic nerve in TRAM and DIEP breast reconstruction. Sparing lateral one third of rectus abdominis muscle does not cause denervated atrophy in the rectus abdominis muscle after TRAM breast reconstruction.

Objective To study the correlation of p53,ki-67 and bcl-2 expression in breast cancer with the clinical response to neoadjuvant chemotherapy,and search for biological markers to guide therapy and predict prognosis.Methods The expression of the p53,ki67 and bcl-2 was examined by immunohistochemical(assay) in samples of breast cancer tissue which taken from 118 cases of operable breast cancer patients.The relationship between p53,ki-67 and bcl-2 and the effect of neoadjuvant chemotherapy was analyzed by(chi-square) test.Results The overall response rate to neoadjuvant chemotherapy was 68.6%.Patients with expression of ki-67 were more likely to respond to treatment.The effect of neoadjuvant chemotherapy had a significantly negative correlation with p53 expression.There was no significant difference between the response to neoadjuvant chemotherapy and bcl-2 expression.Expression of p53 protein was correlated with low(expression) of bet-2.Expression of p53 and ki-67 protein was significantly related.Conclusions The(results) indicated that p53 and Ki-67 expressions are strong prognostic molecular markers that can be a guide for neoadjuvant chemotherapy and prediction of prognosis for patients with breast cancer.

Securin is a multifunctional protein which is encoded by PTTG gene.In the metaphase to anaphase transition during mitosis,Securin is involved in sister chromatid separation.The aberrant expression of Securin is found in many endocrine and related cancers,such as pituitary tomour,thyroid cancer,ovarian cancer,colon cancer et al.The function of Securin in cancer is related to its gene transactivation and association with other poteins like p21,p53.

Objective To observe the clinical efficacy of abdominal acupuncture in treating perimenopausal insomnia.Method Sixty patients with perimenopausal insomnia were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by abdominal acupuncture, while the control group was by regular body acupuncture. The FSH, LH, and E2 contents, and Pittsburgh Sleeping Quality Indext (PSQI) were observed before and after intervention, and the clinical efficacies were compared.Result The total effective rate was 90.0% in the treatment group versus 86.7% in the control group, and the difference was statistically insignificant (P>0.05). The PSQI score was changed significantly in both groups after intervention (P<0.01). After intervention, there was no significant difference in comparing PSQI score between the two groups (P>0.05). The FSH, LH, and E2 contents were significantly changed after intervention in both groups (P<0.01). After intervention, there were no significant differences in comparing FSH, LH, and E2 contents between the two groups (P>0.05).Conclusion Abdominal acupuncture in an effective method in treating perimenopausal insomnia.

Objective To investigate the relationship between regular exercise habit and peak oxygen uptake (VO2 peak ) early after acute ST-elevation myocardial infarction (STEM I).Methods A total of 239 patients who underwent cardiopulmonary exercise testing (CPET) early after STEMI in a single exercise laboratory were enrolled.Influencing factors to VO2peak were analyzed retrospectively.Results There were 53.6％ patients reported to have regular exercise habits before STEMI.No significant difference between patients with and without exercise habit in VO2peak early after STEMI (P =0.317) were found by t test.Mter adjusted by risk factors including demographic features,clinical characteristics and cardiovascular,etc,regular exercise habit was an independent factor for VO2peak (β =1.703,P =0.015 ).Following age-stratification,the significant difference was found between patients with and without exercise habits in VO2peak only in patients aged between 40-49 years old ( P =0.004 ).Conclusions The relationship between regular exercise habit and VO2peak early after STEMI suggests that exercise tolerance of patients with exercise habit will be better than sedentary patients even after STEMI,in particular to patients aged between 40-49 years old.
