Objective:To explore the influence of infusion drop speed on the efficacy of tiopronin for injection combined with sol-vents in the treatment of abnormal liver function. Methods:Totally 74 patients were randomly divided into the observation group and the control group with 37 ones in each. The infusion drop speed was 60-65 drops per minute in the observation group, and that was 30-35 drops per minute in the control group, and the infusion time was controlled in 1h in the observation group and 2h in the control group. The clinical effect and the improvement of liver function were compared between the two groups after a treatment course of 4 weeks. Results:The total effective rate of the observation group(83. 78%) was obviously higher than that in the control group(56. 76%) (P<0. 05) after the treatment, and ALT, AST and TBIL of liver function indices were improved obviously except for ALB in the two group, and the difference was statistically significant between the two groups(P<0. 05). Conclusion:Tiopronin for injection can effectively improve the clinical effect by strictly controlling the time and drop speed of infusion.

Objective To assess the effectiveness of tension-free vaginal tape obturator tape(TVT-O)as treatment of SUI by means of a systematic review and meta analysis.Methods Using the search terms"TVT,TVT-O,SUI,RCT,TOT",the literature in Chinese and English from January 2001 tO March 2007 on the difference of TVT and TVT-O was searched from MEDLINE,PUBMED,EMBASE,Google Scholar,CNKI,WAN FANG DATA,and criteria randomized controlled trials(RCTs)were studied by Meta-analysis in RevMan 4.2.At the same time,Ors of randomized model and fixed model were calculated tO evaluate the sensitivity.Results There were six RCTs that compared TVT-O with TVT.When compared by Subjective cure,TVT-O at 1-17 months were no better than TVT(OR 0.67;95% CI 0.40,1.13).Adverse events such as bladder injuries (OR 0.15;95% CI 0.03,0.66)was less common,where as groin/thigh pain(OR 8.61;95% CI3.03,24.52)was more common;but there were rio significant difference in de novo urgency(OR=1.16;95% CI 0.54,2.47),urinary retention(OR=0.54;95% CI 0.24,1.20)or urinary tract infection(OR=1.07;95% CI 0.61,1.87)between the tWO groups.Conclusions There is no significant difference between TVT and TVT-O.TVT-O group had no bladder injuries complications,but groin/thigh pain was more common.

Objective: To study the effect of gamma irradiation on the permeability of the blood brain barrier(BBB) in rat brains. Methods:The right caudate nucleuses of Sprague Dawley rats were irradiated by OUR XGD gamma units.Maximum dosages of 20,50,75 and 160 Gy were given using a 4 mm collimator.Immunohistochemistry with antibody of serum albumin was used for detecting the extravasation of endogenous serum components.Ultrastructural changes of BBB were observed through injection of lanthanum nitrate into blood vessels. Results: Extravasation of albumin and BBB opening in the right caudate nucleuses were detected as early as 12 h after irradiation at 50,75 and 160 Gy,and were detected 1 d after irradiation at 20 Gy.Immunoreactivity and emematous water reached their maximum after 3 d, gradually decreased during the following few days,and disappeared by day 7(20,50 Gy) or day 14(75 Gy).Irradiation at 160 Gy elicited persistent extravasation of albumin and BBB opening for 14 d. Conclusion: These are transient impairments to BBB after irradiation at 20,50,75 Gy,and persistent impairments after irradiaton at 160 Gy.

This article was aimed to study the intestinal absorption about main active ingredients of pectolinarin and pectolinarigenin in Carboned Cirsium japonicum DC. The absorption rate and absorption rate constant were taken as indicators. The intestinal absorption of pectolinarin and pectolinarigenin were compared by everted rat intestinal sac method among different parts of the small intestine. The results showed that the absorption rate constant of pectoli-narin among duodenum, jejunum, ileum and colon parts were 0.505 1 ± 0.192 7, 0.936 0 ± 0.187 2, 0.732 0 ±0.133 5, 0.251 3 ± 0.027 6 (μg·h-1·cm-2). The absorption rate constant of pectolinarigenin among the duodenum, je-junum, ileum and colon were 0.059 1 ±0.008 3, 0.093 3 ±0.029 2, 0.112 3 ± 0.035 6, 0.029 4 ± 0.009 1 (μg·h-1·cm-2). It was concluded that the absorption of both ingredients increased over time. The absorption of both ingredi-ents in the jejunum and ileum was higher than other parts of the small intestine. The absorption rate of pectolinarin in the entire small intestine was much higher than the absorption rate of pectolinarigenin.

NAC transcription factors involved in plant growth and development, as well as responses to biotic and abiotic stress. RNAi Vectors for SmNAC transcription factors of Salvia miltiorrhiza was constructed by using Gateway cloning technology, in order to further study the function of SmNAC1 transcription factor. According to Gateway cloning technology, the specific fragments of SmNAC1 containing attB adapter was amplified by PCR using ultra-fideling phusion polymerase of NEB. By the BP recombination reaction, the PCR product containing attB was transferred to an donor vector (pENTR/SD/D-TOPO). Finally, SmNACi specific gene was cloned into pK7GWIWG2D plant expression vectors by LR recombination reaction. Experimental results showed that Gateway cloning technology provide a rapid and highly efficient way to clone the interested gene.

Objective:To investigate the anti-inflammatory effects of bitter taste receptor (TAS2Rs) in the treatment of chronic airway inflammation by bitter Chinese medicine.Methods: The experiment was divided into three groups (n=8),namely blank control group,PM2.5 group (the rat models of chronic airway inflammation were established by aerosolized PM2.5 suspension) and PM2.5+limonin group (intervening with the extract from Tangerine peel).The expression of mRNA and protein of inflammatory cytokines and TAS2Rs in bronchial/pulmonary tissue were detected by ELISA,RT-PCR and Western blot respectively.Results: The mRNA and protein expression levels of TNF-α and IL-13 in PM2.5 stimulated group were significantly higher than those in control group,while the TAS2R14 were not significantly changed.The mRNA and protein expression levels of TNF-α and IL-13 in the limonin intervention group was lower than that in the PM2.5 group,and the TAS2R14 were significantly increased.Conclusion: The production and release of inflammatory cytokines in the chronic inflammatory airway can be curbed by inhaling the components of bitter Chinese herbal medicine.And then,the TAS2Rs in the lungs can be activated by the bitter components to increase its expression.Therefore,it is considered that bitter Chinese herbal medicine to play the airway anti-inflammatory effect is achieved through the activation of the airway TAS2Rs.

Objective To explore the impact of ischemic stroke on intestinal barrier changes in dogs.Methods Totally 20 mongrel dogs were divided into 2 groups by random number table with 10 in each.Double silicone cylinders measuring 1.1 mm in diameter and 8 mm in length were placed into their internal carotid arteries in all dogs of group A.Group B served as a control group and received sham operation.Light microscopy was performed for morphological measurement of intestinal epithelial cell.Immunohistochemistry was used to analysis the changes of protein zonula occludens-1(ZO-1)localizing at tight junction of intestinal epithelial cells.Results Ischemic stroke was confirmed by cranial CT scanning in all dogs of group A.Compared with the test results in group B,the occludin and Zo-1 protein levels in group A were significantly lower than those in group B(occludin:0.20 ±0.01 vs 0.22 ±0.01,P =0.007; ZO-1:0.20 ±0.01 vs 0.22 ±0.02,P =0.008).The apoptotic index in group A was significantly higher than in group B(29.04 ± 3.79 vs 6.44 ± 1.24,P =0.002).There was a positive correlation between occludin and ZO-1(R =0.71,P =0.02),and the apoptotic index was negatively correlated with levels of occludin,ZO-1(R =-0.91,P =0.00; R =-0.77,P =0.01).Light microscopy showed that the dogs in group A had intestinal mucousal injuries while no obvious change was detected in group B.Conclusions Dogs with ischemic stroke tend to develop intestinal barrier dysfunction,during which the destruction of tight junction plays a key role.The up-regulated apoptosis of intestinal epithelial cell constitutes one of the cellular bases of intestine injury.
