Objective Compare the value of multislice CT perfusion imaging (MSCTPI)?color brain atlas (CBA)?visual evoked potential mapping (VEP-M) in the diagnosis of acute cerebral infarction.Methods After routine CT was performed,the 27 cases of acute cerebral infarction underwent MSCTPI?CBA?and VEP-M respectively.Results The examination of MSCTPI showed that abnormal perfusion changes were in accordance with clinical symptoms;the examination of CBA showed that in 32 scale local high power shadow presented on the power of ??? of lesion;the examination of VEP-M showed the prolongation of latency of P100?degrade of amplitude on the lesion of the chart,the power of the lesion degraded obviously on the map of distribution of power,and distribution asymmetry.Conclusion Combined use of MSCTPI?CBA?VEP-M in the diagnosis of acute cerebral infarction can remedy the defects and improve diagnostic rate of acute cerebral infarction further.

Objective: To study the effects of enzymolytic extracts of abalone (EEA) on memory of mice, and compared with water extracts of abalone (WEA). Methods: Mice were given EEA or WEA once daily lasting 10 d. Their step-down latency (SDL) and escape latency (EL) in a passive avoidance , and food-hunting time in a maze were determined. Results: EEA 2-8 ml/kg lengthened SDL by 13.7 %-105.3 %, shortened EL by 40.0 %-60.0 % and food-hunting time by 28.3 %-49.4 %, in a dose-dependent manner. EEA reversed ethanol-induced disturbance of memory retrial in a passive avoidance and NaNO2-induced disruption of memory retention in a passive avoidance and maze. Significant action of WEA was not observed until the dose of WEA was increased to 8 ml/kg. Conclusion: EEA improves learning and memory, more effective than WEA.

Objective:To investigate the long-term risk of esophageal cancer from fresh fruit consumption. Methods:In 1985, a total of 29,479 participants aged between 40 and 69 years old were recruited for this study. Demographic characteristics, lifestyle, history of diseases, and food intake frequency were surveyed at the baseline and were then followed up. Through December 31, 2015, a median of 31.79 years of observation was obtained. The primary endpoint was death from esophageal cancer. The hazard ratio and 95%confi-dence intervals for fresh fruit consumption were calculated using a Cox proportional hazard model. Results:Overall, 31.09%of partici-pants reported consuming fresh fruit more than once every week. Compared with participants who never or rarely consumed fresh fruit, those who consumed fresh fruit more than once a week had a lower long-term risk of esophageal cancer. Death rate decreased to 7%among those who ate fresh fruit more than once a week, especially among males (11%) and those with positive smoking history (13%). Conclusion:Fresh fruit consumption is associated with a lower risk of death from esophageal cancer, but the etiological mecha-nism needs to be investigated further.

ObjectiveTo assess the effects of testicular sperm and epididymal sperm on the outcomes of ICSI for patients with obstructive azoospermia.

METHODSWe searched PubMed, MEDLINE, EMBASE, Cochrane, CNKI, VIP, CBM, and Wanfang Database up to December 2015 for published literature relevant to ICSI with testicular or epididymal sperm for obstructive azoospermia patients. According to the inclusion and exclusion criteria, two reviewers independently conducted literature screening, data extraction and quality assessment of the included trials, followed by meta-analysis with the RevMan 5.3 software.

RESULTSA total of 14 studies were identified, involving 1 278 patients and 1 553 ICSI cycles. ICSI with epididymal sperm exhibited a significantly higher fertilization rate than that with testicular sperm (RR = 1.08, 95% CI 1.05－1.11, P<0.01). No statistically significant differences were observed between the epididymal and testicular sperm groups in the rates of cleavage (RR = 1.04, 95% CI 0.99－1.10, P = 0.13), good-quality embryo (RR = 1.01, 95% CI 0.93－1.09,P = 0.85), implantation (RR = 1.14, 95% CI 0.75－1.73, P = 0.55), clinical pregnancy (RR = 1.14, 95% CI 0.98－1.31, P = 0.08), and miscarriage (RR = 0.86, 95% CI 0.53－1.39,P = 0.54).

CONCLUSIONSICSI with epididymal sperm yields a markedly higher fertilization rate than that with testicular sperm, but has no statistically significant differences from the latter in the rates of cleavage, good-quality embryo, implantation, clinical pregnancy, and miscarriage in the treatment of obstructive azoospermia.
