Objective:To determine expression levels of ubiquitin C-terminal hydrolase-L1 (UCH-L1) and serum glial fibrillary acidic protein (GFAP) in patients with acute cerebral infarction and their clinical significance.Methods:A total of 80 patients with acute cerebral infarction in Chongqing Cancer Hospital from January 2014 to February 2016 were enrolled as an observation group.Another 80 healthy people served as a control group.The expression levels of UCH-L1 and GFAP in the 2 groups were detected.Results:Sensibility and specificity for UCH-L1 and GFAP were 75.0％,87.5％ and 81.3％,90.0％,respectively.Receiver operating characteristic curve areas of UCH-L1 and GFAP were 0.670 and 0.757,respectively.There were no significant significance in age,gender,drinking,smoke,diabetes,and hyperlipidemia in the 2 groups (P＞0.05).High blood pressure rate in the observation group was higher than that in the control group (P＜0.05).Spearson/Pearson analysis showed that serum UCH-L1 and GFAP levels were positively correlated with hypertension,but they were negatively correlated with sex,age,diabetes,hyperlipidemia,alcohol consumption,smoking,and other factors.General data at different time in the observation group was not statistically different (P＞0.05).The expression levels of UCH-L1 and GFAP in the observation group was higher than that in the control group (P＜0.05).UCH-L1 and GFAP levels at different time in the 2 groups were not statistically different (P＞0.05).UCH-L1 and GFAP levels in the light,medium,and heavy groups were higher than those in the control group (P＜0.05),while UCH-L1 and GFAP levels in the medium and heavy groups were higher than those in the light group (P＜0.05).There was significant difference between levels of UCH-L1 or GFAP and infarction size at different time in the observation group (P＜0.05).The results of Pearson correlation analysis showed that the levels of serum UCH-L1 and GFAP were positively correlated (r=0.634,P=0.001).Conclusion:The levels of serum UCH-L1 and GFAP are significantly increased at the early stage of acute cerebral infarction,and they have a certain correlation with the severity of cerebral infarction,which can provide a basis for early clinical diagnosis and treatment.

OBJECTIVETo explore the application value of morphology assessment of sperm from fresh semen in routine in vitro fertilization (IVF).

METHODSWe analyzed the morphology of the sperm from fresh or optimized semen samples and, based on the sperm morphology of the raw semen, allocated 908 IVF cycles due to the pure tubal factor to different groups: morphologically normal sperm (MNS) ≤ 4%, > 4% - ≤ 15%, and > 15% in Trial 1 and MNS ≤ 1%, > 1% - ≤ 2%, > 2% - ≤ 3%, and > 3%-- ≤ 4% in Trial 2. We compared the rates of fertilization, cleavage, high-quality embryo, -blastocyst formation, and pregnancy among different groups.

RESULTSThe total fertilization rate was significantly lower in the MNS ≤ 4% than in the MNS > 4% - ≤ 15% and >15% groups (74.40% vs 78.61% and 80.03%, P < 0.01). Compared with the MNS ≤ 1%, > 1% - ≤ 2%, and > 2% - ≤ 3% groups, the MNS > 3% - ≤ 4% group showed remarkably increased rates of 2PN normal fertilization (77.23%, 78.97% and 78.99% vs 85.47%, P < 0.01), cleavage (95.71%, 96.01% and 97.27% vs 98.73%, P < 0.05), and blastocyst formation (53.85%, 49.01% and 49.55% vs 63.41%, P < 0.01). No statistically significant differences were observed in the rates of clinical pregnancy, implantation, early abortion, live birth, or malformation at birth among different groups (P > 0.05).

CONCLUSIONMNS ≤ 4% affected the total rate of fertilization while MNS ≤ 3% reduced the rate of normal fertilization in IVF. However, even MNS ≤ 1% did not result in fertilization disorder or failure. Therefore, teratozoospermia alone was not an indicator of ICSI and sperm mor- phology assessment had no obvious value for predicting the rates of embryo quality, clinical pregnancy, and live birth in IVF.

BACKGROUNDDonor-pretreatment with ulinastatin may influence the liver graft during cold preservation. The aim of this research was to determine whether pretreatment of donor liver with Ulinastatin can attenuate cold preservation injury, and to explore the mechanism by which Ulinastatin affects the donor liver graft.

METHODSOne hundred and forty-four Wistar rats were divided into the Ulinastatin treatment group (T group) pretreated with Ulinastatin 50 000 U/kg and control group (C group) treated with 0.9% normal saline via peritoneal injection prior to the anesthetization. After the abdominal cavity was opened and perfused with cold Ringer's lactate solution, the liver was harvested. The harvested liver was preserved in cold Ringer's lactate solution for 0, 2, 6, 24 hours, at which time the liver tissue was sampled for determination of dry weight and wet weight, Na(+)-K(+)-ATPase and Ca(2+)-ATPase activity, lactic acid dehydrogenase (LDH) activity, lactic acid and malondialdehyde levels. Light microscopy and electron microscopy were used to observe liver morphology. The liver cold-preservation solution was taken for measurement of aspartate aminotransferase (AST) and alanine transaminase (ALT) levels. Correlation between ATPase activity and lactic acid level was analyzed by SPSS 13.0 for Windows.

RESULTSThe morphology in the T group had improved cell boundaries vs. the C group at each time point. Dry weight to wet weight in the T group was lower than in the C group at 6 hours (P < 0.05), but the difference was not significant at 24 hours. ALT levels in the T group were lower than that in the C group at 6 hours (P < 0.05) and 24 hours (P < 0.01). AST levels in the T group were lower than those in the C group at 2 hours (P < 0.05), 6 hours (P < 0.01) and 24 hours (P < 0.01). Na(+)-K(+)-ATPase activity in the T group was higher than in the C group and the mean difference between two groups was significant at 0 hour (P < 0.05) and 2 hours (P < 0.05). Ca(2+)-ATPase activity in the T group was higher than in the C group with the mean difference between two groups significant at 2 hours (P < 0.05). The T group had increased lactic acid levels at 0 hour (P < 0.01) and 2 hours (P < 0.05) compared with the C group, but there was no influence on the LDH activity at the same time. There were no obvious differences in the levels of malondialdehyde between the two groups at any time point. A linear correlation between Na(+)-K(+)-ATPase activity and lactic acid levels (r = 0.295, P < 0.05) was found.

CONCLUSIONSDonor-pretreatment with ulinastatin may protect the cells in a liver graft from ischemia injury during cold preservation; the mechanism may be due to its promotion for cell glycolysis and its preservation of ATPase activity.

OBJECTIVETo investigate and compare the clinical significance of (18)F-FDG single-photon emission computed tomography and computed tomography (SPECT-CT) in the diagnosis and staging of lung cancer.

METHODSFrom July 2005 to July 2007, 71 patients with suspected lung cancer received conventional CT and SPECT-CT examination. Fifty-seven of the 71 patients had definite pathological or cytological diagnosis, consisting of 52 malignant lung tumors and 5 benign pulmonary nodules. Forty-three patients underwent surgical resection with different modes. Thirty-seven of the 43 surgically treated patients had available complete data of CT, SPECT-CT and pathological results.

RESULTSTaking the pathological diagnosis as gold standard, the sensitivity, specificity and accuracy of diagnosing pulmonary lesions suspected as lung cancer were 84.6% (44/52), 80.0% (4/5), 84.2% (48/57) for conventional CT and 92.3% (48/52), 80.0% (4/5), 91.2% (52/57) for SPECT-CT, respectively. If taking the pathological TNM staging results as gold standard, the concordance rates of TNM staging with pathological TNM staging results was 59.5% (22/37) for CT and 67.6% (25/37) for SPECT-CT. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of staging hilar and mediastinal lymph nodes were 76.9%, 79.2%, 78.4%, 66.6%, 86.4% for conventional CT versus 61.5%, 75.0%, 70.3%, 57.1%, 78.3% for SPECT-CT (P > 0.05), respectively. There was no statistically significant difference between conventional CT and SPECT-CT in the accuracy of diagnosing and staging for the suspected pulmonary lesions (P > 0.05).

CONCLUSIONSPECT-CT is likely superior to conventional CT in the diagnosing and staging for lung cancer. It can be used as a non-invasive supplementary tool for differential diagnosis between malignant and benign pulmonary lesions and in diagnosis of lymph node > 1 cm in diameter.
