The Effect of Female Sex on Short-Term Outcomes of Patients Undergoing Off-Pump Versus On-Pump Coronary Artery Bypass Grafting

ABSTRACT Introduction: According to the American Heart Association guideline for coronary artery bypass grafting (CABG), female patients undergoing on-pump CABG (ONCAB) are at higher risk of short-term adverse outcomes than male patients. However, whether off-pump CABG (OPCAB) can improve the short-term outcome of female patients compared to ONCAB remains unclear. Methods: We conducted a meta-analysis to study the effect of the female sex on short-term outcomes of OPCAB vs. ONCAB. A total of 31,115 patients were enrolled in 12 studies, including 20,245 females who underwent ONCAB and 10,910 females who underwent OPCAB. Results: The in-hospital mortality in female patients who underwent OPCAB was significantly lower than in those in the ONCAB group with (2.7% vs. 3.4%; odds ratio [OR] 0.76; 95% confidence interval [CI] 0.65-0.89) and without (OR 0.68; 95% CI 0.52-0.89) adjustment for cardiovascular risk factor. The incidence of postoperative stroke in female patients who underwent OPCAB was lower than in those in the ONCAB group (1.2% vs. 2.1%; OR 0.59; 95% CI 0.48-0.73) before cardiovascular risk factor adjustment but was not significant (OR 0.87; 95% CI 0,66-1.16) after adjustment. There was no significant difference in the incidence of postoperative myocardial infarction between women who underwent OPCAB and those in the ONCAB group (1.3% vs. 2.3%; OR 0.88; 95% CI 0.54-1.43). Conclusion: In contrast to the American Heart Association CABG guideline, female patients who had OPCAB don't have unfavorable outcomes compared with the ONCAB group.

Research progress of new isothermal amplification technology in rapid diagnosis of Plasmodium and other parasites / 中国热带医学

@#Abstract: At present, nucleic acid detection technology based on the PCR principle is commonly used to detect malaria parasites, the existing Plasmodium detection methods mainly include microscopy, antigen immunoassay, and nucleic acid detection,but due to the long detection time, high personnel and equipment requirements, and other shortcomings, its popularization, and application at the grassroots level are limited. What challenges previous Plasmodium detection methods are the lack of experienced professionals and advanced equipment at the grassroots as well as the requirement of rapid detection of large samples under extreme conditions. The isothermal amplification technology developed in recent years has potential application prospects due to its simplicity, rapidity, high sensitivity, and high specificity. This article attempts to review the principles, characteristics, and prospects of various isothermal amplification technologies, and on this basis, focuses on the introduction of recombinase polymerase amplification (RPA) and recombinase⁃aided isothermal amplification (RAA) assay technologies and proposes the use of such recombinant enzyme amplification technologies to achieve rapid and accurate diagnosis of common Plasmodium species possibility and imagination.

Clinical value and surgical method of the pancreatic cancer with PV/SMV invasion / 中华普通外科杂志

Objective To investigate the clinical value and surgical methods of pancreaticoduodenectomy (PD) combined with portal vein (PV)/superior mesenteric vein (SMV) resection and reconstruction in the treatment of pancreatic cancer with PV/SMV invaded by tumor.Methods The clinical data of 21 patients of pancreatic cancer with PV/SMV invaded by tumor (group A) and 62 patients of pancreatic head cancer without PV/SMV invaded by tumor (group B) in the same period were collected and analyzed retrospectively from Jan 2014 to Apr 2017.There were no distinct invasion of celiac artery (CA),hepatic common artery (HCA) and superior mesenteric artery (SMA) in two groups of pancreatic cancer patients.The patients of group A underwent PD combined with PV/SMV resection and reconstruction,and the patients of group B were only treated with PD surgery.The complication rate and overall survival time after PD was compared between the 21 patients of pancreatic cancer with PV/SMV invaded by tumor and the 62 patients of pancreatichead cancer without PV/SMV invaded by tumor.'Results The average overall survival time of 21 patients of pancreatic cancer with PV/SMV invaded by tumor (group A) was 19.2 months,specifically with 1-year survival rate of 57.1％ (12/21),2-year survival rate of 28.6％ (6/21),and 3-year survival rate of 14.3％ (3/21).Meanwhile,the average overall survival time of group B was 19.4 months,specifically with 1-year survival rate of 58.1％ (36/62),2-year survival rate of 30.6％ (19/62),and 3-year survival rate of 14.5％ (9/62).The results indicated that no differences for overall survival time of patients treated with PD including 1,2,3-year survival rate between two groups were found (P ＞ 0.05).Conclusions For pancreatic cancer accompanied by PV/SMV invasion without invasion of SMA,CA and HCA,PD combined with PV/SMV resection and reconstruction are safe and feasible surgical procedures.The surgical reconstruction method was determined according to the location and length of the invaded vessels,and also there were no significant differences on the complication rate and overall survival time after PD between the pancreatic cancer patients with invasion of PV/SMV and the pancreatic head cancer patients without invasion of PV/SMV.

Homeostatic interplay between electrical activity and neuronal apoptosis in the developing neocortex / 基础医学与临床

An interesting feature of neural development in most animal species is that the number of neurons ini-tially produced is greater than the number of neurons belonging to the mature circuits. In the first two weeks of life, a significant number of neurons are eliminated in a short period through apoptosis. Although we have been very clear that in the peripheral nervous system(PNS),neurotrophic factors and apoptosis play an important role in controlling the neurons survival, but the situation in central nervous system (CNS) remains unknown. In the rodent cortex, the peak of apoptosis coincides with spontaneous, synchronous neural activity pattern. In this arti-cle, we review the recent research results which proved the important role of electrical activity in the brain cortex neuron survival, described the function of Ca2+and neurotrophic factors in translating electrical activity into pro-survival signals, and finally discuss the clinical impact of the tight relation between electrical activity and apopto-sis of neurons.
