To optimize the Scutellaria baicalensis extraction process, the filter paper method and the bacteriostatic ratio method were adopted to determine the in vitro bacteriostatic efficacy of water extracts and 60% alcohol extracts from S. baicalensis. The quantitative analysis of multi-components by single-marker (QAMS) was used to determined the contents of four active components, baicalin, wogonoside, baicalein and wogonin. In addition, with the bacteriostatic ratio and the overall desirability of the contents of four active components as indexes, the orthogonal experiment was adopted to detect the effect of water addition, extraction frequency and extraction time. The optimal extraction process was to add 12 times of water for the first time, 10 times of water for the second time, extract for 2 time, 2 h for each time. This optimization process is stable and feasible, with a higher bacteriostatic ratio in extracts.

Objective To understand the current situation of occupational exposure and occupational safety attitudes among nursing students in Kunming Medical University, and to find effective interventions to improve nurses' occupational safety,and to reduce occupational exposure.Methods 854 students in Kunming Medical University were investigated by a questionnaire survey, including Demographic characteristics, Occupational exposure conditions, Occupational safety attitude and Gathers, quit intention . The correlations between occupational safety attitudes and occupational exposure were analyzed with Simple Linear Correlation.Results There were 94.30%female respondents,and only 5.70%male respondents.The average age of respondents was 22.52±2.90 years. The Simple Linear Correlation analysis showed that correlation between Negative attitude and occupational exposure was positive correlated, the occupational exposure and Support from managers, and Optimistic were negative correlation ( <0.05) .Conclusions Occupational safety and attitude are related to occupational exposure. Nursing students should apply standardized operation to improve the professional quality and ability. Schools should strengthen the education of occupational protection for nursing students. Hospital management should regularly organize nurses to study occupational exposure protection knowledge,give full affirmation of the nurse's achievements in the work, and offer certain reward appropriately.

OBJECTIVETo explore the experimental conditions for H2O2 to injure astrocytes and the effect of baicalin in protecting neurons and astrocytes from oxidative stress injury.

METHODSNeurons and astrocytes from forebrain of rats were cultured in vitro and treated with H2O2, baicalin and combination of the two, respectively. The cell viability or survival rate was determined using MTT.

RESULTSEffects of H2O2 in different concentrations on survival rate of astrocytes showed significant difference (F = 28.569, P < 0.01) in a dose-dependent manner. Degrees of H2O2 injury, with the same concentration of H2O2, on cells with different seeding density were also significantly different (F = 5.439, P < 0.01), and dose-dependently. Baicalin didn't influence the survival rate of neurons and astrocytes when the concentration was within 2.5-40 mumol/L (for neurons, F = 0.49, P > 0.05; for astrocytes, F = 1.001, P > 0.05), but baicalin showed significant antagonism to the injury of oxidative stress (for neurons, F = 24.384, P < 0.01; for astrocytes, F = 5.000, P < 0.01). The higher the concentration of bainalin, the higher the cell survival rate.

CONCLUSIONA model of astrocytes oxidative injury induced by H2O2 is established. Baicalin shows no toxicity on neurons and astrocytes when the concentration is within 2.5-40 mumol/L, but could antagonize the H2O2 caused oxidative injury on cells in a dose-dependent manner.

BACKGROUNDSurgical interventions are the main treatment for primary congenital glaucoma (PCG). This study aimed to compare the efficacy and safety between viscocanalostomy and mitomycin C (MMC)-trabeculectomy in patients with PCG.

METHODSA total number of 43 patients with PCG who underwent either viscocanalostomy (group 1) or MMC- trabeculectomy (group 2) between June 2003 and June 2008 were retrospectively reviewed. The patients' intraocular pressures (IOPs) were examined before surgery and on day 1, week 1, month 1, month 6, and month 12 post-operative. Mean horizontal corneal diameters, success rates, intra- and post-operative complications were compared between the two groups.

RESULTSPre-operative IOPs were (31.96 ± 3.90) mmHg in group 1 and (32.56 ± 4.00) mmHg in group 2. At the last visit, IOPs were (16.78 ± 2.20) mmHg and (15.77 ± 2.60) mmHg, respectively (P < 0.001); the complete success rates of group 1 and group 2 were 45.9% and 67.4%, respectively, and the difference was not statistically significant (P = 0.158). There were no major complications occurred in the two groups.

CONCLUSIONSBoth viscocanalostomy and trabeculectomy can lower IOP in PCG patients effectively. Although there was no major complications occurred in both groups, viscocanlostomy may decrease the probability of postoperative haemorrhage, hypotony, cataract, or choroid effusion.

OBJECTIVETo investigate the significance of prostate specific antigen (PSA) examination in seminal plasma of infertile patients.

METHODSEighty-five infertile patients were collected randomly. The level of PSA in seminal plasma was detected by ELISA method. The correlations between PSA and several seminal parameters including sperm density, motility and acid phosphatase (ACP) were analyzed.

RESULTSThe PSA, ACP concentrations and sperm motility in 65 cases of abnormal liquefaction patients were obviously lower than those in normal liquefaction patients(P < 0.01). But there were no significant differences in sperm density among the three groups(P > 0.05). PSA levels were significantly correlated with ACP and sperm motility(P < 0.01).

CONCLUSIONSThe seminal PSA in infertile patients is markedly correlated with semen liquefaction. The abnormal quality and quantity of PSA can result in a depression of sperm motility and subinfertility.

OBJECTIVETo study the burning characteristics of moxa stick.

METHODSA self-designed moxa stick burning temperature measuring device, which was assembled with ALTEC intelligence digital setter and SJ-600 thermocouple, was used to conduct next four experiences: 1) embedding a thermocouple inside a moxa stick to measure peak burning temperature; 2) pulling a thermocouple embedded in the moxa stick at the proper rate to detect combustion stability; 3) elucidating temperature distribution of transverse section by measuring the temperature in the center, radius midpoint and lateral; 4) drawing temperature-time-space curves by pulling the thermocouples in the former three observation points.

RESULTSThe experiment indicated that the burning temperature peak of three-year moxa stick (Hubei Herbal Medicine St. Qichun Technology Co., Ltd.) was 848 degrees C which had good combustion stability. Furthermore, the temperature in the center, radius midpoint and lateral of transverse section were 843 degrees C, 731 degrees C and 410 degrees C, respectively, and its burning temperature-time-space curves was drawn, which showed the real-time burning temperature and the peak burning temperature and were regarded as ultimate indice to integrate the formers.

CONCLUSIONThe measuring system elaborately reflecting the burning features of moxa stick may provide reference for manufacture industry of moxa stick quality criteria for its convenience and accuracy.

OBJECTIVETo investigate the expression of proline-rich tyrosine kinase-2 (Pyk2) in human primary colorectal carcinoma (CRC) and it's prognostic significance.

METHODSThe expression of Pyk2 was retrospectively examined with immunohistochemistry (IHC) in 108 tissues of primary CRC. The correlation of Pyk2 expression to prognosis and relevant clinical factors were analyzed.

RESULTSThe rate of Pyk2 low-expression in CRC was 56.5% (61/108). The expression of Pyk2 correlated significantly to the histological grade (P < 0.05) and the TNM stage (P < 0.05), while no correlation between Pyk2 expression and age, tumor size (P > 0.05). Patients with Pyk2 over-expression had significantly higher 5-year survival rate (66.0%) than those with Pyk2 low-expression (31.4%). Pyk2 expression, together with carcinoma histologic grade and TNM stage were prognostic factors to CRC on the multivariate analysis.

CONCLUSIONSPyk2 expression can be a prognostic factor to the CRC patients together with other predictors.
