In developing the Benbutu oilfield in Xinjiang, hole size irregularities were often encountered in the water- and hydrocarbon-containing sections, and these greatly affect the quality of the cementing job and damage the reservoirs. To protect the oil and gas reservoirs in the Benbutu oilfield, an elastic polymer microsphere NWL was developed through soap-free emulsion polymerization and was characterized. A reservoir protective agent CBJ was formulated with NWL, a selected anti water-block agent, a kind of rigid acid soluble nanometer particles (CaCO3) and a petroleum resin in a certain quantity ratio. Laboratory experiment was conducted to evaluate CBL in the aspects such as: the compatibility of CBL with the sizes of formation fractures, the acid solubility and oil solubility of CBL, the compatibility of CBL with the drilling fluids presently used, and the reservoir protection performance of CBL. CBL was also tested in field operations. CBL has the particle size distribution that is suitable for plugging formation fractures, good acid solubility and oil solubility. Drilling fluids treated with CBL have filtration rate reduced by about 20%, and percent permeability recovery by more than 80%. Field application and laboratory study show that CBL has good reservoir protection effect, it can be used to protect the reservoirs of Benbutu oilfield in accordance with the local conditions and maximize the production of oil wells.

Objective To investigate the effect of lactobacillus acidophilus on the expression of nitric oxide (NO) and its oxidative mediators, and to explore the anti-atherosclerosis mechanism of lactobacillus acidophilus. Methods Twentyfour male SPF rats were randomly divided into normal diet group, high-fat diet group and lactobacillus acidophilus group, with 8 rats in each group. The rats in the normal diet group were fed with normal diet, and the high-fat diet group was fed with high-fat diet + intraperitoneal injection of vitamin D3 + immune injury + FeSO4 to establish an atherosclerosis model. The rats in the lactobacillus acidophilus group were intragastrically administered with 0.5 mL of lactobacillus acidophilus per day (1×109 CFU/mL) on the basis of the high-fat diet. Rats were weighed at the 4th, 8th and 12th weekends. After 12 weeks of feeding, the serum was taken from abdominal aorta to detect the contents of oxidized low density lipoprotein (oxLDL), NO, arginine, arginase, and peroxynitrite (ONOO-). The aorta was isolated to observe the morphological change by HE staining. The expressions of eNOS and iNOS mRNA were detected by Real-time PCR, and the expressions of NF-κB p65 subunits were detected by Western blot assay. Results (1) There was no significant difference in body weight between the high-fat diet group and the lactobacillus acidophilus group during the whole experiment (P＞0.05), but both were significantly increased compared with those of the normal diet group (P < 0.01). (2) HE staining showed that the aorta formed a wide range of atherosclerotic lesions in the high-fat diet rats, and the aortic morphology was significantly improved in the lactobacillus acidophilus group. Only endothelial cell proliferation was found, and no smooth muscle cell necrosis was observed in this group. (3) Compared with normal diet group, the serum expressions of oxLDL, ONOO- , arginase, aortic iNOS mRNA and nuclear NF-κB p65 were increased in high-fat diet group (P＜0.01), and the serum arginine content and aortic eNOS mRNA expression levels were decreased (P＜0.01). While lactobacillus acidophilus can just reverse the above changes (P＜0.01). Conclusion Lactobacillus acidophilus may exert anti-atherosclerotic effects by regulating the expression of NOS, increasing NO bioavailability, and protecting endothelial function.

Objective: To investigate the relationship between Bilirubin blood lipid Comprehensive index and apolipoprotein B and the severity of coronary lesions of female patients with coronary artery disease(CAD). Methods: A total of 246 cases of female patients with coronary angiography were divided into 2 sets of groups.(1)According to the results of coronary angiography, the female patients were divided into the CAD group(n=141) and normal control group(n=105);(2)By Gensini scoring system, the female patients were divided into 4 quartile groups: 1 st quartile group(n=35), 2 nd quartile group(n=32), 3 rd quartile group(n=39) and 4 th quartile group(n=35). The blood level of total bilirubin(TBIL), direct bilirubin(DBIL), indirect bilirubin(IBIL), total cholesterol(TC), triglyceride(TG),low density lipoprotein cholesterol(LDL-C), high density lipoprotein cholesterol(HDL-C), apolipoprotein A/B(ApoA/B) level were measured. Bilirubin blood lipid Comprehensive index [TC/(HDL-C+TBIL), LDL-C/(HDL-C+TBIL)] were calculated. Results:(1) The levels of TC, TG, LDL-C and ApoB in CAD group were higher than those of the normal control group; the HDL-C, ApoA, TBIL, DBIL and IBIL were lower than those of the normal control group(P0.05); Compared with the normal group, the ratios of TC/(HDL-C+TBIL)and LDL-C/(HDL-C+TBIL) were increased(P0.05).(2)By Gensini scoring system, the level of TC, LDL-C, ApoB, TBIL, DBIL, IBIL,ratios of TC/(HDL-C+TBIL) and LDL-C/(HDL-C+TBIL) were different among 4 groups(P<0.05).(3)Correlation analysis showed that TC/(HDL-C+TBIL), LDL-C/(HDL-C+TBIL) and ApoB were positively related to Gensini scoring system(r=0.538, P<0.05; r=0.670, P<0.05 and r=0.462, P<0.05). But TBIL, DBIL, IBIL were negatively related to Gensini scoring system(r=-0.485, P0.05; r=-0.564, P0.05 and r=-0.359, P0.05). Conclusions:(1)Bilirubin blood lipid Comprehensive index and apolipoprotein B were significantly higher than the control group, while TBIL, DBIL, IBIL decreased.(2)Bilirubin blood lipid Comprehensive index and apolipoprotein B were positively related to the severity of coronary artery lesions of female CAD patients.

Objective To investigate the action mechanism of the enhanced external counter pulsation (EECP) for treat-ing angina pectoris. Methods Fifty-six patients with chronic ischemic angina pectoris in our hospital from January 2014 to September 2015 were selected and randomly divided into the treatment group(39 cases) and the control group(17 cases). The two groups were performed the routine therapy and examinations. The patients in the treatment group were performed EECP accompa-nied by the medical staff in the whole process. ELISA was adopted to detect MMP-9 and TNF-αlevels. The curative effects of the two groups were comparatively analyzed. Results The effective rate after therapy in the treatment group was 92.3%(36/39), which was higher than 41.2%(7/17) in the control group,the difference was statistically significant(P<0.01);the MMP-9 and TNF-αlevels after treatment in the two groups were superior to those before treatment ,moreover the treatment group was superior to the control group,the difference was statistically significant(P<0.05). Conclusion The EECP therapy can decrease the levels of TNF-αand MMP-9 and improve the symptoms of angina pectoris. [ABSTRACT FROM AUTHOR]
