Objective To evaluate the risk of cardiovascular adverse events using nonsteroidal anti-inflammatory drugs during the perioperative period.Methods A systematic review of formally published in English and Chinese literature was conducted by using computerized database on PubMed, Web of Science, Medline, Cochrane Library, CNKI and Wanfang database.The literature about controlled clinical study of nonsteroidal anti-inflammatory drugs in perioperative use, a prospective cohort study and a retrospective review were collected.The cardiovascular risk was evaluated by the number of adverse cardiovascular events cases (myocardial infarction, angina, myocardial ischemia, arrhythmia) occurred during the period of drug use.The relevant data was extracted and their heterogeneity was tested.Results A total of 8 articles including 15 623 patients met the inclusion criteria, including 5 articles (n=13 019) on non-selective nonsteroidal anti-inflammatory drugs, and 3 articles (n=2 604) about selective (cyclooxygenase 2) COX-2 inhibitors.Nonsteroidal anti-inflammatory drugs used in the perioperative or a short term would reduce the risk of adverse cardiovascular events (OR=0.59, 95%CI 0.45-0.77, P=0.000 1), non-selective nonsteroidal anti-inflammatory drugs using in the perioperative or a short term would reduce the risk of adverse cardiovascular events, the difference being statistically significant (OR=0.42, 95%CI 0.31-0.58, P＜0.001).A selective COX-2 inhibitor using in the perioperative or short-term might increase cardiovascular adverse events (OR=2.53, 95%CI 1.26-5.09, P=0.009).Conclusion Non-selective nonsteroidal anti-inflammatory drugs should be chosen for patients at high risk of adverse cardiovascular events during the perioperative period.

Objective To study the expression of microtubule-associated protein-2 (MAP-2) in the CA3 region of the hippocampus and any effect of acupuncture combined with exercise training on the recovery of learning and memory after experimental cerebral infarction.Methods Eighty Wistar rats were randomly divided into a sham-operation group (n = 8 ) and an operation group (n = 72 ) subdivided randomly and equally into a model group, an exercisetraining group and an acupuncture plus exercise training group, with 24 rats in each group. After right middle cerebral artery occlusion or a mock operation, the expression of MAP-2 in the CA3 region of the hippocampus was detected with immunohistochemistry 1, 3 and 5 weeks after the operation. Learning and memory function was assessed at the 5th week post operation.Results MAP-2- positive fibers were arranged in an orderly way and distributed densely in the shamoperation group. After cerebral infarction, number of MAP-2 positive neurons and dendrite fibers decreased in the CA3 region of the affected side. A week after the operation, MAP-2 positive fibers had increased significantly in the acupuncture plus exercise group compared with the model group and the exercise group. At the 3rd and 5th week post operation, expression of MAP-2 and optical density had increased significantly compared with the model group and the exercise training group. At the 5th week post operation, Y maze discrimination and learning tests showed that learning and memory had improved significantly more in the acupuncture plus exercise training group compared with the model group and the exercise training group.Conclusions Exercise training combined with acupuncture can promote changes in dendritic plasticity and increase MAP-2 expression in the CA3 region after cerebral infarction. This may be correlated positively with the recovery of learning and memory after cerebral infarction, at least in rats.

Phenol-Chloroform method was used to extract DNA from human peripheral blood, and a combination of polymerasechain reaction and restriction fragment length polymorphism were used to analyze the distribution of genotypes and alleles of the polymorphism site of hepatic lipase. Results The genotype and allele distribution of HL-514C/T polymorphism were significantly different between the whole CHD group and control group(P

Tumors are believed to consist of a heterogeneous population of tumor cells originating from rare cancer stem cells (CSCs). However, emerging evidence suggests that tumor may also originate from non-CSCs. To support this viewpoint, we are here to present definitive evidence indicating that the number of tumorigenic tumor cells is greater than that of CSCs in tumor, and tumor can also derive from non-CSCs. To achieve this, an idealized mathematical model was employed in the present study and theoretical calculation revealed that non-CSCs could initiate the occurrence of tumor if their proliferation potential was adequate. Further, experimental studies demonstrated that 17.7%, 38.6% and 5.2% of tumor cells in murine B16 solid melanoma, H22 hepatoma and Lewis lung carcinoma, respectively, were potentially tumorigenic. Thus, based on the aforementioned findings, we propose that the scarce CSCs, if exist, are not the sole source of a tumor.
