Objective To investigate the dynamic expression of nitric oxide synthase(NOS) in the apoptosis of primary cultured rat cortical neruons following hypoxia/reoxygenation(H/R) and the protective role of extract of ginkgo biloba(EGB). Methods The cortical neurons of E16-17 days fetal rat were primarily cultured.The apoptosis model of primary cultured cortical nurons following H/R was established by using W-G staning,electromicroscopy,TUNEL staining.The dynamic expression of NOS different H/R times was investigated with NADPH-diaphorase histochemical method. Results H/R can cause apoptosis of primary cultured rat cortical neurons.In the experiment of H-2R-0,H-4R-0, H-6R-0,H-8R-0 and H-2R 18,H-4R 18,H-6R 18 H-8R 18,the apoptosis cells occurred after 4 hour hypoxia.The increasing of apoptosis cell acted as time-dependence and the peak value was at H-8R 18.The expression of NOS increased both after 2 hour hypoxia and reoxygenation 18 hour after 8 hour hypoxia compared with the normal control group.EGB could inhibit the increasing and decrease the percentage of apoptosis.Conclusion The apoptosis of primary cultured rat cortical neurons could be induced by H/R.The increasing of NO might be one of the mechannisms of apoptosis.EGB could singnificantly inhibit the apoptosis by means of inhibiting the expression of NOS and reducing the production of NO.;

OBJECTIVETo investigate the effect of light intensity on growth and photosynthetic of Chrysanthemum morifolium.
METHODThe growth characteristics of C. morifolium were measured under different treatments (100%, 80%, 60%, 40% and 20% of full sunlight). The photosynthetic characteristics and chlorophyll fluorescence parameters of leaves under different light intensity were determined by a LI-6400 photosynthesis system and a PAM-2100 chlorophyll fluorescence system.
RESULTWith the reduction of irradiance, the diameter of the stem reduced, plant height, leaf length, leaf width and length/width raised, assimilation product increased; Content of photosynthetic pigment increased between light intensity 100%-40% reduced under 20% treatment, chlorophyll a/b decreased. Light compensation point (LCP), apparent quantum yield (AQY) increased first and reduced later, photosynthesis rate (P(n)), stomatal conductance (G(s)), intercellular CO2 concentration (C(i)) and transpiration rate (T(r)) decreased, stomatal limitation value (L(s)) rose. Chlorophyll fluorescence parameters F(v)/F(m) increased, phiPS II, F(v)'/F(m)', ETR and qP increased between irradiance 100%-60%, NPQ decreased, such as phiPS II decreased and NPQ increased when irradiance was lower than 40%.
CONCLUSIONWeak light condition was unfavorable to the growth of C. morifolium and the light conditions of culture should be control between 80%-60% of full sunlight.

OBJECTIVETo compare the clinical effect of the double eyelid blepharoplasty with central minimal incision and with three minimal incisions. Methods: From Jul. 2010 to May 2012, 268 cases (Group A) received double eyelid blepharoplasty with central minimal incision, while 102 cases (Group B) underwent double eyelid blepharoplasty with three minimal incisions. Photos were taken immediately, and 1,2, 4, 8,12 weeks after operation. Operation time, recovery time and postoperative complications were evaluated and recorded. The operation time and recovery time were analyzed by Wilcoxon rank sum test. The postoperative complications were analyzed by chi square test. The satisfactory degree was analyzed by t test.
RESULTSThe operation time in Group A was (25.63 ± 3.74) min, compared with that (29.90 ± 4.13) min in Group B (Z = -8.011, P <0.01). Meanwhile, the recovery time in Group A was shorter than that in Group B (Z = -15.887, P <0.01). The occurrence rate of postoperative complications,including hematoma,recurrence and scar hyperplasia in Group A was also lower than that in Group B. At the same time, the satisfactory degree in Group A was(97.302 ± 1.764), which was higher than that(88.628 10.880) in Group B (t = 12.650, P <0.05).
CONCLUSIONSThe double eyelid blepharoplasty with central minimal incision, which is suitable for all cases except those who has serious blepharochalsais, has more advantages than double eyelid blepharoplasty with three minimal incisions.

Objective:
To explore mediation of emotional regulation in the association between aggression behavior and non-suicide self-injury among rural middle school students.
Methods:
A multi-stage stratified random cluster sample of 14 291 middle school students from 15 cities in five provinces of China (Anhui, Yunnan, Guangdong, Heilongjiang, Hubei). A structured questionnaire was used to assess non-suicide self-injury, emotional regulation and aggressive.
Results:
During the past year, about 28.51% of participates reported self-injury, with 13.39% of them had 5 times or more. The five dimensions of aggressive behavior were positively correlated with non-suicide self-injury(P<0.01), emotional regulation was negatively correlated with non-suicide self-injury(P<0.01). The mediating effect of emotional regulation between aggression (physical aggression, verbal aggression, indirect aggression, anger and hostility) and non-suicide self-injury was found significant, the ratio of whose were 25.93%, 22.73%, 19.61%, 27.55% and 18.80%, respectively.
Conclusion
Emotional regulation plays a mediating role in adolescent self-injury and aggression, indicating self-injury and aggression could be prevented by enhancing emotional regulation among adolescents.

RESULTThe linear response ranged from 1.02-20.48 mg x L(-1) for quercetin (r = 0.9994, n = 5), 1.03-20.54 mg x L(-1) for luteolin (r = 0.9992, n = 5), 1.12-22.40 mg x L(-1) for apigenin (r = 0.9995, n = 5), 1.01-20.22 mg x L(-1) for acacetin (r = 0.9998, n = 5), respectively. Recoveries were 101.3% with RSD 1.3% for quercetin, 100.62% with RSD 1.4% for luteolin, 98.42% with RSD 1.7% for apigenin and 99.02% with RSD 0.8% for acacetin. A significant difference (alpha = 0.01) among the contents of four flavonoids and total flavonoids was found.
CONCLUSIONThe method is quick, simple and repeatable for simultaneous determination of quercetin, luteolin, apigenin and acacetin in Flos Chrysanthemi Indici.

OBJECTIVETo study the effect of light intensity on physiological and biochemical characteristics of Chrysanthemum morifolium at the vegetative stage.
METHODThe dynamic response of physiological and biochemical indexes of Ch. morifolium were measured under different treatments (100%, 80%, 60%, 40% and 20% of the full sunlight) at the vegetative stage.
RESULTThe physiological and biochemical indexes of Ch. morifolium showed dynamic changes with the progress of growth and the increase of the treatment time. The soluble sugar content decreased when the light intensity reduced, and had a significant positive correlation with the light intensity. Soluble protein content rose firstly and fell later, malondialdehyde content increased, superoxide dismutase and catalase activity decreased initially and increased afterwards.
CONCLUSIONProper shading benefits the nitrogen accumulation of Ch. morifolium at the vegetative stage, and reduces the strength of stress condition. The suitable light environment for growth of Ch. morifolium at the vegetative stage is about 80%-60% of full sunlight and the optimum treatment time is 20-40 days.
