Objective To investigate the effect of propofol on nNOS expression after focal cerebral ischemia-reperfusion in rats and the possible mechanism of protective effect of propofol on brain. Method Seventy-eight male Wistar rats, weighting 250 ~ 300 g, were randomly divided into 3 groups:(1)Sham operation group (S group, n=6) was performed with scham operation; (2) Ischemia-reperfusion group (group I-R, n=36) was subjected to 2-hour right middle cerebral artery occlusion and then reperfusion was followed, saline (1 mg/kg) was injected into the right lateral cerebral ventricle using microsyringe before reperfusion;(3) Propefol group (group P, n=36) was injected with propofol (1mg/kg) into the right lateral cerebral ventricle using microsyringe right after ischemia. Group I-R and group P were divided into 3 subgroups according to the reperfusion time: 1 h, 3 h and 6 h. The neurological function of all rats were tested before reperfusion. The cerebral infarction area of the whole brain was calculated with TIC staining (n=6). The pathological change of brain was observed from HE staining (n=6) and the nNOS protein expression was obtained by immuno- histochemical method (n=6). Results Compared with I-R group, the neurological function was better in group P(P

To improve ethanol production in Saccharomyces cerevisiae,an integration plasmid pUPGKAT with PGK promoter(phosphoglycerate kinase promoter),adh1 gene(the coding sequences of alcohol dehydrogenaseⅠ) and CYC1 terminator(Cytochrome c transcription terminator) was constructed.Firstly,a fusion fragment composed of PGK promoter and adh1 gene was generated by over lap extension PCR and ligated into pUG6 resulting in plasmid pUPGKA.Subsequently,CYC1 termi nator was amplified from pSH65 by PCR and ligated to the SpeⅠand SacⅡrestriction site of pUPGKA.To integrate PGK-adh1-CYC1 into S.cerevisiae genome,pUPGKAT was digested by TthⅢⅠand the lin-earized plasmid was used to transform S.cerevisiae YS2-△adh2(adh2 disrupted strain) by lithium acetate method.The yeast mutant YS2-△adh2-adh1 which had the adh1 gene placed under the PGK promoter and harbored the adh2 deletion was constructed.Anaerobic fermentation showed overexpression of adh1 by PGK promoter resulted in a 8.84% higher ethanol production compared to YS2-△adh2.

Acyl carrier protein is an essential component involved in the biosynthesis of DHA(Docosahexaenoic Acid) via PKS(Polyketide synthase) pathway,which takes the growing acyl chain from one enzyme to another.One cDNA clone,with high homology of ACP,was isolated from Schizochytrium sp.FJU-512 cDNA library.The deduced amino acid sequence contained 142 residues with isoelectric point of 5.04 and had the 4'-phosphopantetheine prosthetic(4'-PP) binding site.The target fragment was digested with BamHⅠ/HindⅢand inserted into the expression vector pET-30a resulting in the plasmid pET-30a/acp.The recombinant vector was transformed into E.coli BL21(DE3) and induced by IPTG.SDS-PAGE analysis demonstrated that ACP was effectively expressed.

To develop an ophthalmic preparation of Shedan, an in situ forming gel was prepared with the formulation containing 18% of poloxamer 407 and 5% of poloxamer 188 by response surface designs plus central composite designs. The rheology results showed that LVE range gamma should limited within 0.5%, Shedan high-frequency region, and the thixotropy recovery time is less than 5 seconds. The phase transition temperature was 33.25 °C according to curve of storage modulus and loss modulus determined by temperature scanning. Surface tension and osmometer of it determined by surface tension meter and dew point osmometer were 36.43 mN · m(-1), and 320.6 mOsm · kg(-1), respectively. Fluorescein sodium was selected as the marker to monitor the corneal residence time, and the results showed that Shedan gel could prolong drug residence for 180 min. In line with zero-order kinetics, releases of muscone and salvianolic acid B in vitro depends on gels erosion. The results of rabbit ocular irritation experiments suggested that Shedan in situ forming gel was biocompatible and nonirritant. In conclusion, a novel Shedan in situ forming gel was developed and characterized for potential drug treatment of retinal vein occlusion.

Objective To screen the altered gene expression profile of hippocampus after traumatic brain injury(TBI)in rats. Methods Rats(n=3)in experimental group underwent moderate fluid-percussion(F-P)brain injury and the hippoeampus sample in the injured hemisphere was removed and conserved in liquid nitrogen three hours later.The rats(n=5)of the control group underwent the same procedure except for injury.Mfymetrix rat genome 230 2.0 array was used to detect the gene expression profile of hippocampus in two groups and find the altered gene expression profile. Results A total of 159 genes in the experimental group changed significantly(≥2 folds)compared with the control group,of which 136 genes were up-regulated and 23 genes down-regulated. Conclusions The significant gene expression changes of hippocampus,especially a large mount of up-regulated genes,are detected after moderate TBI in rats,suggesting that the secondary injury following TBI is a procedure involving multiple factors.

Objective To set up a rat model with acute traumatic coma and identify the variation of microRNA in mesencephalon. Methods After rats were injured moderately by central fluid percussion system, tissues of the mesencephalon were removed one hour after injury. RNA of brain tissue of the mesencephalon was isolated for microRNA array by using the exiqon microarray system. The data were analyzed statistically by Genepix Pro 6.0 after hybridization results were scanned and fluorescence intensity standardized. Resets Hybridization results showed 33 microRNAs with up-regulated expressions but 38 microRNAs with down-regulated activity. Conclusion Expression of microRNA array shows marked changes in the tissues of the mesencephalon in rats with traumatic coma, as may be injury mechanism of traumatic coma and also a way of neurobiological protection of coma.

OBJECTIVETo explore the difference in the efficacy and effect mechanism of subcortical ischemic vascular disease (SIVD) complicated with depression between acupuncture and medication.

METHODSSixty patients were randomized-into an acupuncture group and a medication group, 30 cases in each one. In the acupuncture group, acupuncture was applied to Baihui (GV 20), Shuigou (GV 26), Fengfu (GV 16), Fengchi (GB 20) and the others, once a day, 6 times a week. The treatment of 4 weeks made one session and totally 2 sessions were required. In the medication group, nimodipine 30 mg, three times a day and fluoxetine 20 mg, once a day were prescribed for oral administration, for 8 weeks totally. Before treatment, at the end of the 4th week and at the end of the 8th week of treatment, cerebral blood flow velocity (CBFV) and solubility CD40 ligand (sCD40L) were determined respectively. The scores in Montreal cognitive assessment (MoCA) and Hamilton' s depression scale (HAMD) were evaluated in the two groups. The efficacies on cognitive function and depression symptoms were compared in the patients between the two groups. Results Compared with the outcome before treatment, mean blood flow velocity (Vm) of middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA) was increased significantly at the end of the 4th week of treatment in the two groups (all P<0.05). At the end of the 8th week, Vm was increased much significantly (all P<0.01). The differences were not significant in comparison between the two groups (all P>0.05). Compared with the expression before treatment, sCD40L was reduced significantly after treatment in the patients of the two groups (all P<0.01), but the differ- ence was not significant between the two groups (all P>0.05). Compared with that before treatment, MoCA score was increased significantly after treatment in the two groups (all P<0.01), HAMD score was reduced sig- nificantly (all P<0.01), the differences were not significant in comparison between the two groups (all P>0.05). The total effective rate of cognitive improvement was 86.7% (26/30) in the acupuncture group and was 80.0% (24/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05). The total effective rate of the improvement in depression was 93.3% (21/30) in the acupuncture group and was 86.7% (26/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05).

CONCLUSIONAcupuncture could significantly increases CBFV and reduces serum sCD40L expressions in the patients of SIVD complicated with depression, and significantly improves cognitive function and relieves depression symptoms. The efficacy of it is similar to that of western medication. The increase of serum sCD40L expression is possibly involved in the occurrence and development of SIVD. Reducing sCD40L expression contributes to the alleviation of damage induced by cerebral ischemia and reperfusion.
