Objective To evaluate the elderly coronary in-stent restenosis risk factors and the incidence of restenosis. Methods Coronary angiography in 143 cases of patients with coronary heart disease were randomly selected, analyzing the characteristics of coronary heart disease, and 89 patients of them were reviewed coronary angiography, restenosis was observed, and the restenosis factors including age, sex, hypertension, diabetes, hyperlipidemia and coronary lesions, stent properties were analyzed. Results Statistical multi-vessel disease in patients with coronary heart disease was 73.9% ,restenosis rate was 23.5%. One narrow and contrast the age of the patients without stenosis and no statistically significant difference between lipids. The number of diabetes cases in the two comparison groups,stent length and stent volume were significant different. One bare stent restenosis rate was significantly higher than the drug-eluting stent group. Conclusion The results showed that diabetes ,stent length,multiple stents, stent restenosis,were the relevant factors of coronary restenosis.

BACKGROUND:There may be tumor stem cells during metastasis and recurrence of liver cancer.The number of tumor stem cells is very few,so it is difficult to be identified.Thy-1 is a surface marking protein of oval cells.Specific marker can indirectly confirm the existence of tumor stem cells in the tumor,which is a focus in recent studies.OBJECTIVE:To study whether Thy-1 positive marked oval cells was expressed in hepatoma carcinoma cells,and investigate its screening and identification.METHODS:Flow cytometry was used to identify that Thy-1 positive expression in hepatoma carcinoma cells HepG2 and BEL-7402 and normal hepatocytes QSG-7701.Immunomagnetic bead sorting was utilized to select hepatoma carcinoma cells with Thy-1.Immunofluorescence was used to identify selected efficiency.Naked mouse inoculated with hepatoma carcinoma cells in the skin test was assigned to three groups.In the Thy-1~+ cells group,naked mice were inoculated with Thy-1~+ cells (5×10~5/mouse)underneath the skin of the back.In the HepG2 cell positive control group,naked mice were inoculated with HepG2 cells(0.5×10~7/mouse)underneath the skin of the back.In the Thy-1' cells negative control group,naked mice were inoculated with Thy-1~- cells(0.5×10~7/mouse)underneath the skin of the back.Tumorigenicity in each group was observed one month later.RESULTS AND CONCLUSION:Thy-1 expression in hepatoma carcinoma cells HepG2 and BEL7402 was significantly greater compared with normal hepatocytes QSG7701(P＜ 0.05).Positive rate of immunofluorescence staining was 85% in the Thy-1~+ cell group,1% in the HepG2 cell positive control group,0% in the Thy-1~- cell negative control group.There were nubble of five mice in HepG2 cell positive control and Thy-1~+ groups,and the volume was large.However,there was one nubble in Thy-1~- group,and the volume was significantly small(F=144.568,P＜ 0.05).Results indicated that hepatoma carcinoma cells contained Thy-1 labeled positive oval cells-like stem cells,which may be tumor stem cells in hepatoma carcinoma cells.

Objective To evaluate the clinical application value of flow fluorescence assay in determination of serum pepsinogenⅠ and Ⅱ.Methods The precision of flow fluorescence assay in the detection of serum pepsinogen Ⅰ and Ⅱ were evaluated. Methodology comparison were conducted between flow fluorescence assay and enzyme-linked immunosorbent assay(ELISA)kit through detecting clinical samples.The reference ranges for PGⅠ and PGⅡ/PGⅠ ratio of healthy population were established. The levels of PGⅠand PGⅡ/PGⅠ ratio were detected in serum samples of patients suffering superficial gastritis,atrophic gastritis and gastric cancer.Results The within-run and between-run coefficient of variation of PGⅠ were 4.26%-5.35% and 6.73%-7.75%,respectively.And those of PGⅡ were 5.48% - 6.42% and 8.46% -8.85%,respectively.Methodology comparison be-tween flow fluorescence assay and ELISA demonstrated good linear correlations.The linear equation wasY =0.91 1X -22.635(r=0.966,P <0.05)and Y =0.892X -0.548(r=0.980,P <0.05)for PGⅠ and PGⅡ,respectively.The lower limit of the reference range of PGⅠ and PGⅡ/PGⅠ ratio were 32.77 ng/mL and 4.1 6,respectively.The PGⅠ and PGⅠ /PGⅡ ratio of patients suf-fering atrophic gastritis and gastric cancer were statistically significantly lower than those in patients suffering superficial gastritis (P <0.05).Conclusion The flow fluorescence assay could conduct simultaneous detection of PGⅠ and PGⅡwith good methodo-logical performance and high efficiency.The determination of PGⅠ and PGⅡlevels through flow fluorescence assay could provide laboratory basis for the screening and diagnosis of atrophic gastritis and early gastric cancer.

OBJECTIVE:To stndy the clinical efficacy and safety of somatostatin combined with pantoprazole sodium in the treatment of severe acute pancreatitis(SAP). METHODS:By retrospective analysis,98 patients with SAP were divided into control group and observation group by the different treatment. All patients were treated by routine treatment of SAP. Based on it,patients in control group were given Pantoprazole sodium for injection 40 mg adding into 0.9% sodium chloride injection 100 ml,iv,twice a day;patients in observation group were given Somatostatin for injection 3 mg adding into 0.9% sodium chloride injection 100 ml based on the treatment of control group,by micro intravenous continuous intravenous infusion,0.25 mg/h,twice a day.Both cours-es were 7 d. The clinical data was observed,including clinical efficacy,improvement time of signs and symptoms(remission time of stomachache,recovery time of gastrointestinal function,withdrawal time of ventilator) and tumor necrosis factor-α(TNF-α), high-sensitivity C-reactive protein (hs-CRP),interleukin-8 (IL-8) levels and the incidence of adverse reactions before and after treatment. RESULTS:The total effective rate in observation group was significantly higher than control group,and the improve-ment time of signs and symptoms was significantly shorter than control group,with significant differences(P<0.05). After treat-ment,the inflammatory cytokine levels in 2 groups were significantly lower than before,and observation group was lower than con-trol group,with significant differences(P<0.05). The incidence of adverse reactions in observation group was significantly lower than control group,with significant difference(P<0.05). CONCLUSIONS:Based on the routine treatment,somatostatin combined with pantoprazole sodium has better efficacy than only pantoprazole sodium,with better safety.

Neovascularization plays an essential role in the process of renovation in tissue damage,tumor growth, and hormones action. Parathyroid hormone (PTH) is one of the basic hormones that regulate the serum calcium, phosphorus, and bone metabolism. In recent years, studies involving the neovascularization-mediated effects of PTH on metabolism are becoming more and more popular and wider. Based on recent researches, the purpose of this paper is to summarize the changes of angiogenesis while PTH interacts with its target organs, especially interacts with osseous tissue.

Objective Diabetic mellitus is one of the major threats to human health.The prevalence of diabetes mellitus is growing rapidly worldwide.Patients with diabetes mellitus are at increased risk for cardiovascular diseases.Diabetic cardiomyopathy (DC) is related to diabetes-specific metabolism,but the mechanism is not entirely clear.Recent studies suggest that abnormal myocardial energy metabolism and reduced number of myocardial cells may be the important pathophysiological mechanism that leads to heart function impairment of diabetes patients.Mitochondria are not only an important place generating cellular energy,also involved in the apoptotic and death process of cells.Therefore,mitochondrial dysfunctions play a key role in the process of DC.Mitochondrial permeability transition (MPT) is a center for information exchange within and outside the mitochondria and plays a key role in the maintenance of mitochondrial function.MPT works through the mitochondrial permeability transition pore (MPTP).In our recent studies,it was found that MPTP function changed in DC and its abnormality could be corrected by specific AT I receptor antagonist.These findings are important for better understanding DC.
