OBJECTIVETo observe the effect of SHENG MAI ZHUSHEYE on the movement parameters and viability of human sperm in vitro.

METHODSWe collected sperm samples from 33 normal fertile men, divided each into two, and cultured them in vitro with SHENG MAI ZHUSHEYE + Hams-F10 and Hams-F10 alone, respectively. Then we measured the straight line velocity (VSL), curvilinear velocity (VCL), average path velocity (VAP) and the amplitude of lateral head displacement (ALH) of the sperm by computer-aided semen analysis at 0.5, 1, 2, 4, 8 and 12 h. And the sperm viability was detected.

RESULTSVCL was significantly higher at 8 h (P < 0.05) and very significantly higher at 12 h (P < 0.01) in the SHENG MAI ZHUSHEYE + Hams-F10 group than in the Hams-F10 group. VSL, VAP and ALH were significantly increased in the former group at 4, 8 and 12 h as compared with the latter (P < 0.05). The sperm viability was significantly decreased in the Hams-F10 group at 12 h (P < 0.05).

CONCLUSIONSHENG MAI ZHUSHEYE can improve sperm movement parameters and increase sperm viability in vitro.

Objective To investigate the performance of triple rule-out with(M-slice spiral CT in the combined examination of pulmonary artery,thoracic aorta and coronary artery for patients with acute chest pain.Methods Seventy patients who presented with acute chest pain were included in the study.All of the patients underwent retrospective ECG-gated 64-slice computed tomography triple rule-out examination to evaluate the pulmonary arteries,thoracic aorta and coronary arteries.Multi-planar reconstruction(MPR), maximum intensity projection(MIP),curved-planar reconstruction(CPR)and volume rendering(VR) were used to display pulmonary arteries,thoracic aorta and coronary arteries.We evaluated the image quality of coronary artery and the enhancement of the pulmonary artery and thoracic aorta to estimate if the examination can fulfill the clinical demand for the differential diagnosis of acute chest pain.Results The mean scan time was(8.5?1.0)s,and the dose of contrast medium injected was 100 ml.There were 95.7%(67/70)of patients whose CT values detected in the pulmonary artery and thoracic aorta after enhancement were ≥200 HU.The image quality of 85.8%(720/839)coronary segments was classified as excellent,8.6%(72/839)as good,and 5.6%(47/839)as poor.There were 20 cases with coronary stenoses≥50%,2 cases with pulmonary embolism,and 2 cases with aortic dissection.Conclusion The triple ride-out examination with 64-slice spiral CT could depict pulmonary artery,thoracic aorta,and coronary artery in 8 s with good image quality.It has great potential in the etiological diagnosis for the patients with acute chest pain.

OBJECTIVETo explore the categories of drugs causing hepatotoxicity and analyze the clinical and histological features of the corresponding drug-induced liver injury (DILI), in order to gain insights into potential diagnostic factors for DILI.

METHODSA total of 138 DILI patients treated at our hospital from April 2008 to April 2010 were retrospectively analyzed. The responsible drug for each DILI case was recorded. The Roussel Uclaf Causality Assessment Method (RUCAM) had been used to diagnose DILI. Only cases that had scored as highly probable or probable (more than or equal to 6 points by RUCAM) were included in this study. The patients' general condition, clinical manifestations, and serum biochemical and immunological parameters were assessed. Sixty-six of the patients underwent liver biopsy, and were assessed for liver pathological changes. Clinical and laboratory test data were collected and used to classify the total 138 cases as hepatocellular injury, cholestatic, or mixed hepatocellular-cholestatic types.

RESULTSWithin our patient population, the leading cause of DILI was Chinese herb medicine, accounting for 53.62% of cases. Antibiotics were implicated in 7.97% of cases, and dietary supplement in 6.52% of cases. Correlation between the clinical features and histological injury pattern was stronger at the time of biopsy (more than or equal to 3 days after laboratory results) (kappa = 0.63, P less than 0.05) than at the onset of DILI (kappa = 0.25, P less than 0.05). All modified hepatic activity index (HAI) necroinflammatory scores and fibrosis scores were more severe in the cholestatic and mixed injury types than in the hepatocellular injury type (P less than 0.01 and P less than 0.05, respectively).

CONCLUSIONChinese herbal medicine, dietary supplements and antibiotics were the main causes of DILI in our patient population. The clinical and histological features correlated well, especially at later stages of DILI. The degree of inflammation and fibrosis was significantly higher in cholestatic and mixed hepatocellular-cholestatic injury types than in the hepatocellular injury type. Assessment of both clinical and pathological features may represent a more accurate diagnostic method for DILI.

OBJECTIVETo perform genome-wide linkage analysis for an ethnic Han Chinese pedigree with schizophrenia in order to locate the susceptibility genes.

METHODSGenomic DNA was extracted from 4 mL of peripheral blood using conventional phenol-chloroform method. Illumina Infinium Linkage 24 BeadChips chip was used for determining the genotypes through detection of single nucleotide polymorphisms (SNPs). After processing the raw data using Illumina BeadStudio software, two-point nonparametric linkage analysis and two-point parametric linkage analysis were performed with Merlin software.

RESULTSBy two-point nonparametric linkage analysis, 27 sites with high LOD scores (LOD=0.63-0.75, P U+003C 0.05) were identified. Among these, 3 SNPs(rs993694, rs992690 rs1861577) were located in 12p12.3 region, whilst the remainders were located in 4p12-q22 region. Two-point parametric linkage analysis under a dominant model has yielded almost identical results.

CONCLUSIONChromosomal regions 4p12-q22 and 12p12.3 probably contain susceptibility genes for schizophrenia.

OBJECTIVE: To explore the effect of miR-143 regulating matrix metalloproteinase(MMP)-13 expression on migration and invasion of osteosarcoma cells. METHODS: The mouse osteosarcoma cell line 143B cells were cultured in 96-well plates, and blank group, negative group, positive group, and intervention group were set up. Then, the blank group did no treatment 50 μg miR-143 mimic was added to positive group, negative group added equal mimic NC (control sequence of miR-143 mimic), the intervention group was added 50 μg miR-143 mimic and 10 μg MMP-13 protein, all groups continued to culture for 3 to 6 hours, and finally the serum was aspirated to treat for half an hour. The protein expressions of miR-143 and MMP-13 in each group were measured by fluorescence quantitative PCR experiment and Western blot experiment, respectively, and the invasion and migration abilities of cells were measured by Transwell and scratch experiments. RESULTS: The expression of MMP-13 protein in the positive group and the intervention group was significantly lower than that in the blank group, and the positive group was lower than the intervention group (P<0.05);The mean numbers of invasive cells in blank group, negative group, positive group and intervention group were (1 000.01±44.77), (959.25±46.32), (245.04±4.33), (634.06±33.78) cells/field, respectively;the scratch healing rate of the positive group and the intervention group was significantly lower than that of the blank group, and the positive group was lower than the intervention group (P<0.05). CONCLUSION MMP-13 is a target of miR-143, which can reduce the migration and invasion ability of osteosarcoma cells by inhibiting the expression of MMP-13.

Objective To study the clinical efficacy and safety of direct intraventricular administration of recombinant tissue plasminogen activator (rt-PA) in patients with intraventricular hemorrhage (IVH). Methods A series of 10 patients with IVH, admitted to our hospital from November 2005 to October 2007, was studied for the effect of direct intraventricular administration of rt-PA. In all patients, ventriculostomy was performed in unilateral or bilateral ventricles through frontal burr holes as soon as the IVH was diagnosed on CT. Four or 6 h later, 4 to 8 mg rt-PA was slowly injected through the ventricular catheter. The injection was repeated at 12-24 h intervals until serial CT scans showed a substantial reduction of intraventricular blood. CT scan was conducted at 24-48 h after injection of rt-PA. The outcome of patients was evaluated according to Glasgow Outcome Scale (GOS)on day 30 after IVH. Results The total dose of rt-PA per patient ranged from 13 to 24 mg. On day 30after IVH, 4 patients had a good recovery, 3 patients were moderately disabled, 2 were severely disabled,and 1 was in a vegetative state, and no patient died. There were no hemorrhagic and intracranial infectious complications resulted from treatment, and no catheter became obstructed With blood clot.Conclusions Intraventricular administration of rt-PA can speed the resolution of intraventricular blood clot, keep the ventricular drainage catheter open, reduce the space-occupying effect of the blood clot.Intraventricular administration ofrt-PA is effective and safe, and can improve the patients' prognosis.

Objective To investigate the photodynamic effect mediated with 5-aminolevulinic acid (5-ALA) on U251 human glioma cells. Methods Fluorescence microscope and confocal laser scanning microscope were used to detect the localization of Pp Ⅸ in U251 human glioma cells. The cells with/without 5-ALA were irradiated at the wavelength of 635 nm. MTT assay was used to measure the cell survival after laser irradiation. Results 5-ALA cocultured with U251 cells successfully produced endogenous Pp Ⅸthat was observed distributively in the cytoplasm, but not in nuclear region. The overall survival rates of the U251 glioma cells photodamaged by ALA-PDT decreased as the incubation time went by or the 5-ALA concentration increased, while peaked at the incubation time of 6 h and the 5-ALA concentration of 2.0mmol/L. Without one of 5-ALA and light irradiation, the survival rate of the cells had no significant difference compared with that of cells of the control group. Conclusion The 5-ALA-induced PDT appears to be a promising therapy for human glioma. The optimal incubation time may be 6 h and the optimal 5-ALA concentration be 2.0 mmol/L.

OBJECTIVE: To investigate the effect of P53 expression on prognosis of patients with double expressor lymphoma(DEL) and the interaction between the expression of MYC, BCL2 and P53 in diffuse large B-cell lymphoma(DLBCL). METHODS: Eighty-eight patients with newly diagnosed DLBCL from 1st September 2012 to 31th May 2018 in Shanxi Dayi Hospital affiliated to Shanxi Medical University were selected. The expressions of MYC、BCL2、P53、CD10、BCL6、MUM and Ki-67 were tested by immunohistochemistry method. The overall survival of patients was analyzed by the Kaplan-Meier method and compared by the log-rank test. The prognostic effect of MYC, BCL2 and P53 expression was analyzed by univariate and multivariate analysis. RESULTS: Compared with patients without P53 expression, the patients with P53 expression had higher LDH level, higher NCCN-IPI scores, lower response to chemotherapy，poorer overall survival(OS) and a higher rate of death(P<0.05). In patients who had diffuse large B-cell lymphoma associated with MYC, BCL2 expression or MYC/BCL2 double expression， compared with the patients whom without P53 expression, P53 expression associated with a significant worse OS (P<0.05). The patients with concurrent MYC and P53 expression had a worse OS, compared with patients with either P53 or MYC expression(P<0.05). In patients with MYC/P53 co-expression, BCL2 expression did not correlate with poorer survival significantly(P>0.05). Among lymphoma patients with MYC/P53, MYC/BCL2 and BCL2/P53 co-expression, the patients with MYC/P53 co-expression had the worse OS (3 year OS rate：31.6%), followed by the subgroup of patients with MYC/BCL2/P53(3 year OS rate：46.2%), patients with MYC/BCL2/P53 expression(3 year OS rate： 636%) showed a longer OS compared with the other two subgroups（P<0.05）. Multivariate analysis demonstrated that P53 expression and NCCN-IPI were independent prognostic factors in this patient cohort. CONCLUSION P53 and MYC expressions have a synergistically negative prognostic effect in DLBCL patients. P53 expression augments the negative prognostic effect of MYC/BCL2 double expression. Patients with MYC/P53 co-expression have a worse prognosis in comparison with the patients with MYC/BCL2 double expression.

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.
