Objective To determine if the shortened exposure of oocytes to sperm can influence the insemination rate and the results of IVF-ET. Methods A total of 217 women were included.They were divided into study group (105 cases) and control group (112 cases). In study group the shortened insemination was used.The oocytes were washed 2 hours after the insemination and transferred into the fresh medium.In control group the classical procedure was used.The oocytes were inseminated by ICSI.The number of retrieved oocytes,fertilized oocytes,the number of embryos were counted and the pregnancy rate was evaluated. Results There was no statistically significant difference between the study and control group in the number of retrieved oocytes (1163 vs 1752),number of embryos (1084 vs 1097),and pregnancy rate ( 42.9% vs 42.9%). Conclusions The shortened exposure of oocytes to sperm is a simple and effective way in IVF-ET.

Objective To evaluate the effects of hydrogen-rich saline on chronic inflammatory pain in rats.Methods Thirty-two male Sprague-Dawley rats,aged 8-10 weeks,weighing 200-250 g,were randomly divided into 4 groups (n =8 each) using a random number table:control group (group C);complete Freund's adjuvant (CFA) group;hydrogen-rich saline group (group H2);CFA + hydrogenrich saline group (CFA+H2 group).Chronic inflammatory pain was induced by injecting CFA 100 μl into the plantar surface of the left hindpaw in CFA and CFA + H2 groups.In H2 and CFA + H2 groups,0.6 mmol/L hydrogen-rich saline 5 ml/kg was injected intraperitoneally once a day for 7 consecutive days starting from 1 day after injection of CFA,while the equal volume of normal salinc was given instead of hydrogen-rich saline in C and CFA groups.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 1 day before CFA injection and 1,3 and 7 days after CFA injection.The rats were sacrificed after the last measurement of pain threshold on day 7 after CFA injection.The left lumbar segments (L4 5) of the spinal cord were removed for determination of nuclear factor E2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) expression by Western blot.Results Compared with C group,no significant change was found in the MWT,TWL and expression of Nrf2 and HO-1 in H2 group,and the MWT was significantly decreased,the TWL was shortened,and the expression of Nrf2 and HO-1 was up-regulated in CFA and CFA+H2 groups.Compared with CFA group,the MWT was significantly increased,the TWL was prolonged,and the expression of Nrf2 and HO-1 was up-regulated in CFA+H2 group.Conclusion Hydrogen-rich saline can alleviate chronic inflammatory pain in rats,and activation of Nrf2/ARE signaling pathway in the spinal cord is involved in the mechanism.

Objective: To observe the clinical effect of Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method versus ordinary acupuncture on superficial fascia for treating neck type cervical spondylopathy in Kyrgyz. Methods:A total of 64 Kyrgyz patients conforming to the diagnostic criteria of neck type cervical spondylopathy were included. The patients were randomized into a Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and a conventional acupuncture group, with 32 cases in each group. Patients in the Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were treated with Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method to stimulate the superficial fascia, the stimulation sites were primarily located at bilateral sides of the cervical vertebra as well as the trigger points in shoulder-neck region; patients in the conventional acupuncture group were punctured at the same acupoints, with twirling reducing method, and the depth of insertion was determined by the treated region. Patients in both groups received treatment every day for a succession of 5 d as a course, with a 2-day interval between 2 courses, and the whole treatment lasted for 3 courses. After 3 courses of treatment, the McGill pain questionnaire (MPQ) and neck disability index (NDI) were measured to compare the clinical effect between the two groups. Results: After treatment, scores of MPQ and NDI scale dropped when compared with those before treatment, and the differences showed statistical significance (allP<0.05); scores of MPQ and NDI in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were substantially lower than those in the conventional acupuncture group, and the differences showed statistical significance (allP<0.05). The total effective rate was 96.9% in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and the cured rate was 78.1%, which were higher than 81.3% and 40.6% in the conventional acupuncture group, and the differences showed statistical significance (bothP<0.05). Conclusion: Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method by stimulating superficial fascia to treat cervical spondylopathy in Kyrgyz can produce a better clinical effect than conventional acupuncture treatment, and is effective in improving pain and stiffness in patients, and thus is worth clinical popularization.

Objective:To evaluate the role of the left ventricular ejection fraction (LVEF) in coronary artery bypass grafting(CABG)patients. Methods: From 2004 to 2005,215 patients underwent CABG and there were 36 cases with LVEF0.40(normal LVEF group). Correlative data of the two groups were compared and analyzed statistically. Results: Compared with the normal EF group, the EuroSCORE of the low EF group was much higher (mean 6.4?1.7) and many more patients of the low EF group had concomitant moderate to severe mitral valve insufficiency and aneurysm that needed simultaneous surgical operation(55.6%).Two patients died in hospital(5.5%)in the low EF group whereas five patients in the normal EF group(2.8%, P

Objective:To develop a method for the determination of palladium in bendamustine hydrochloride by GFAAS. Meth-ods:The sample was destroyed by heat, and the content of palladium was determined by GFAAS with the detection wavelength of 247. 6 nm. Results:The absorbance and the content of palladium showed a good linear relationship within the range of 20-60 ng· ml-1(r=0. 998 4). The average recovery of palladium was 102. 9%(RSD=1. 7%, n=9). Conclusion: The method is sensitive and simple, which can be used for the determination of palladium in bendamustine hydrochloride.

Objective To investigate the effect of galectin-3 (Gal-3) on the pathogenesis of primary biliary cirrhosis (PBC).Methods The clinic data of 72 PBC patients at different stages were analyzed and the serum levels of Gal-3 were detected in 72 PBC patients and 20 controls by enzyme linked immunosorbent assay (ELISA).Independent t-test,variance analysis,LSD-t and Pearson correlation analysis were adopted for data analysis.Results The serum Gal-3 levels were significantly higher in PBC patients than those of healthy controls [(855±634) pg/ml,(463±446) pg/ml,P<0.05].With the progression of disease,the levels of Gal-3,platelets,hemoglobin,albumin,IgM and complement C3 gradually declined,but the level of total bilirubin gradually elevated(P<0.05).There was positive correlation between Gal-3 and immunoglobin IgM,complement C3 levels (r=0.330,P=0.005; r=0.357,P=0.002).There was negative correlation between Gal-3 and total bilirubin levels (r=0.350,P=0.003).Conclusion The Gal-3 can participate in the immune-mediated inflammation of PBC and the formation of liver fibrosis.The levels of Gal-3,platelet count,hemoglobin,albumin,IgM,complement C3 and total bilirubin could be regarded as laboratory parameters for the evaluation of the disease severity and prognosis.
