The viscosity property of Cr^3＋, Al^3＋, and compound ion cross-linked polymer gel solution in the anaerobic and aerobic environment was investigated aiming at meeting the practical demand of the oil field. The viscosity reserving effect after adding the biocide and the gelation in the anaerobic and aerobic environments was also studied in the paper. The results indicate that the viscosity of the cross-linked polymer gel solution caused by the water produced in aerobic environment is higher than that in anaerobic environment, and that the viscosity value of the cross-linked polymer gel solutions after adding biocides has improved to some extent and polymer gel has gelated well in anaerobic environment.

OBJECTIVE: To evaluate the effectiveness of an adjuvant therapy from Traditional Chinese Medicine for supplementing Qi and promoting blood circulation(CMSQPBC) on left ventricular remodeling in patients after myocardial infarction(MI).METHODS: Randomized controlled trials were identified in the Cochrane Library, Embase, Web of Science, PubMed, China National Knowledge Infrastructure Database, Chinese Biomedical Literature Database, China Science and Technology Journal Database, Wanfang databases, reviews, and reference lists of relevant articles. The weighted mean difference(WMD) was calculated for changes in the left ventricular ejection fraction(LVEF), LV end-diastolic volume(LVEDV) and LV end-systolic volume(LVESV) from baseline to follow-up(> 3 months) by using random-effects Meta-analysis. The primary outcome was change in LVEF, and secondary outcomes were changes in LV dimensions including LVEDV and ***: A total of 10 trials(enrolling 854 participants, median follow-up six months) evaluated the association between CMSQPBC and changes in LV function and volume. Compared with the control group, CMSQPBC significantly improved LVEF(854 patients;WMD: 4.97%, 95% CI: 3.78-6.15;P luSION: CMSQPBC may reverse deleterious pathological remodeling after myocardial infarction. Higher quality and more rigorous randomized trials with larger sample sizes are needed to further confirm the findings.
