Abstract?AlM:To compare the effects of different adjustable suture in glaucoma trabeculectomy on early tear film function.?METHODS:Sixty-eight cases of primary glaucoma ( 76 eyes) during January 2012 to June 2014 in our hospital were selected and divided into exposure conjunctival suture group ( 34 cases, 36 eyes ) and embedded conjunctival suture group ( 34 cases, 40 eyes ) according to treatment. Adjustable suture exposed conjunctival suture and embedding conjunctival suture was given to two groups, respectively. lntraocular pressure ( lOP ) before and after treatment 7, 14, 30d were observed and Schirmer test, tear break-up time, No Hikaru sensitivity and the occurrence of adverse reactions after treatment 1, 30d were recorded.?RESULTS: After the treatment, the mean lOP of two groups were decreased significantly ( P < 0. 05 ). The average lOP after treatment of 1d in the two groups were not statistically different (P>0. 05), after treatment 7, 14, 30d embedded conjunctival suture group was significantly higher than that of exposure conjunctival suture group ( P<0. 05). After 1d of treatment, Schirmer test, tear break-up time, No Hikaru sensitivity of two groups compared no significant difference (P<0. 05). After treatment 7, 14, 30d embedded conjunctival suture group Schirmer test, tear break- up time, was significantly superior to expose conjunctiva suture group (P<0. 05). The 30d package after treatment of conjunctival suture group buried adverse reaction rate was significantly lower than that of exposed conjunctival suture group (P<0. 05).? CONCLUSlON: Trabeculectomy operation with adjustable thread embedding conjunctival suture has few effects on the tear film function in patients with early postoperative complications, lower, and operation effect is better than that of exposed conjunctival suture.

According to the transcriptome dataset of Panax notoginseng, the key geranylgeranyl pyrophosphate synthase gene (GGPPS) in terpenoid backbone biosynthesis was selected to be cloned. Using specific primer pairs combining with RACE (rapid amplification of cDNA ends) technique, the full-length cDNA sequence with 1 203 bp, which containing a 1 035 bp open reading frame, was cloned and named as PnGGPPS. The corresponding full-length DNA sequence contained 2 370 bp, consisted of 1 intron and 2 exons. The deduced protein PnGGPPS contained 344 amino acids and shared more than 73% identity with GGPPS from Ricinus communis and Salvia miltiorrhiza. PnGGPPS also had specific Aspartic acid enrichment regions and other conserved domains, which belonged to the Isoprenoid-Biosyn-C1 superfamily. The quantitative real-time PCR showed that PnGGPPS expressed in different tissues of 1, 2, 3 years old root, stem, leaf and 3 years old flower, and the expression level in 3 years old leaf was significant higher than that in other organs, which suggested that it might not only be involved in the regulation of the growth and development, but also be associated with the biosynthesis of chlorophyll and carotenoids, the development of chloroplast, the shade habit and the quality formation of P. notoginseng.

OBJECTIVETo evaluate that the effect of formula of removing both phlegm and blood stasis in improving cardiac function of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome.

METHODTotally 36 Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Danlou tablet group, and Tanyu Tonzhi Fang(TYTZ) groups with doses of 2. 0, 1. 0 and 0. 5 g kg-1, with six in each group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary heart disease model of phlegm-stasis cementation syndrome. After the operation, they were administered with drugs for 8 weeks. The changes in the myocardial ischemia were observed. The changes in the cardiac function and structure were detected by cardiac ultrasound and noninvasive hemodynamic method.

RESULTCompared with the normal control group, the model group showed significant increase in myocardial ischemia and SVR and obvious decrease in CO, SV and LCW in noninvasive hemodynamic parameters (P <0.05 or P <0.01). The ultrasonic cardiogram indicated notable decrease in IVSd, LVPWs, EF and FS, and remarkable increase in LVIDs (P<0. 05 orP<0.01). Compared with the model group, TYTZ could reduce the myocardial ischemia, strengthen cardiac function, and improve the abnormal cardiac structure and function induced by ischemia (P <0. 05 or P <0. 01).

CONCLUSIONTYTZ shows a significant effect in improving cardiac function of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome. The clinical cardiac function detection method could be adopted to correctly evaluate the changes in the post-myocardial ischemia cardiac function, and narrow the gap between clinical application and basic experimental studies.

This study is to investigate the effect of baicalin (BL) against oxidative injury stress of SH-SY5Y cells induced by H2O2 and the possible mechanism. SH-SY5Y cells were pre-incubated with baicalin (25, 50, and 100 micromol x L(-1)) for 12 h prior to exposure to H2O2 (150 micromol x L(-1)) for 24 h. The viability of SH-SY5Y cells was measured by MTT assay. The contents of LDH and NO were determined. The percentage of apoptotic cells was assessed by flow cytometry (FCM). The content of Caspase-3 was tested by immunofluorescence histochemical method. BL at 50 and 100 micromol x L(-1) separately increased the cell viability and up-regulated SIRT1, reduced the contents of LDH, NO, Caspase-3 and the apoptotic percentage of SH-SY5Y cells. This study results suggest that baicalin could inhibit the H2O2-induced neuronal apoptosis. The further mechanism studies show that baicalin inhibit apoptosis via reducing Caspase-3 expression and up-regulating SIRT1.

OBJECTIVETo research the mechanism of TX0201 abstracted from heart-regulating formula in the treatment of rat with Alzheimer's disease (AD).

METHODThe rat models of AD were induced by A beta(1-40) injected into the bilateral amygdale. All rats were divided into five groups at random, namely control group, model group, heart-regulating formula group, TX0201 group and aricept group. The rats were intragastrically treated with different solution respectively for 20 days. The effect of TX0201 on spatial learning and memory ability of these rat models was investigated with the method of Morris water maze. By using the method of RT-PCR, the expression of apoptosis associated genes (such as Bcl-2 and Bax) in cerebral cortex and hippocampus of rats were examined.

RESULTHeart-regulating formula, TX0201 and aricept could significantly improve the spatial learning and memory ability of rats. Heart-regulating formula could comprehensively redress the abnormal expression of Bax mRNA and Bcl-2 mRNA in cerebral cortex and hippocampus. TX0201 could rectify the abnormal expression of Bax mRNA in cerebral cortex and hippocampus. Aricept could regulate the abnormal expression of Bax mRNA in cerebral cortex.

CONCLUSIONTX0201 could ameliorate the learning and memory ability of these model rats by alleviating neuron apoptosis by means of regulating the abnormal expression of Bax mRNA in brain.
