AIM: To evaluate the effects of over-expression of cellular repressor of E1A-stimulated genes(CREG) mediated by retrovirus on neointima formation in injured rat carotid.METHODS: The pluronic F127 containing pLNCX/CREG or pLNCX/GFP retroviral vectors was placed around the injured rat carotid.The neointima,media areas and the intima to media ratio were calculated.Expressions of CREG,SM ?-actin and Ki-67 were detected.RESULTS: The GFP expression was observed at day 2 in pLNCX/GFP groups.The expression of exogenous CREG was also significantly increased in arteries at day 2 after pLNCX-CREG infection.Over-expression of CREG significantly suppressed neointima formation,attenuated the expression of Ki-67 and up-regulated SM ?-actin expression.CONCLUSION: Over-expression of CREG inhibits VSMCs proliferation and promotes VSMCs differentiation after vascular injury.It suggests that modulation of CREG expression or activity may be a viable approach to treat neointimal restenosis after percutaneous coronary intervention.

OBJECTIVE To map a comprehensive metabolic pathway of herbacetin in rats, specifically, to elucidate the biotransformation of herbacetin in vivo and to simultaneously monitor the pharmacokinetic process of both parent drug and its major metabolites. METHODS liquid chromatography/ion trap mass spectrometry (LC/MSn) and ultra-liquid chromatography coupled with mass spectrometry (UPLC/MS) were combined in the current study for qualitative and quantitative determinations of herbacetin and its metabolites in bile, urine and feces after both oral and intravenous administration of herbacetin to rats. Enzyme kinetic studies on the intestinal and hepatic metabolism of herbacetin were further conducted to elucidate metabolic profiles of herbacetin in rat tissues and organs. Additionally, plasma concentration profiles of herbacetin and its metabolites in rats were obtained to characterize the overall pharmacokinetic behavior of herbacetin. RESULTS It was found that herbacetin was excreted primarily from rat urine in the form of glucuronide-conjugations. Subsequent in vitro enzyme kinetic studies and in vivo pharmacokinetic investigations suggested an extensive hepatic metabolism of herbacetin and the high exposure of herbacetin- glucuronides in systemic circulation. The clearance, half- life and bioavailability of herbacetin in rats were determined as (16.4±1.92)mL·kg-1·min-1, (11.9±2.7)min, and 1.32%, respectively. On basis of these findings, a comprehensive metabolic pathway of herbacetin in rats was composed. In addition, a physiology based pharmacokinetic (PBPK) model was successfully developed with the aid of the GastroPlus to simulate the pharmacokinetic process of herbacetin in rats. Application of the PBPK modeling can provide a useful starting point to understand and extrapolate pharmacokinetic parameters among different species, populations, and disease states. CONCLUSION After oral administration, herbacetin was subjected to colonic degradation and extensive first pass metabolism, with glucuronidation as its dominating in vivo metabolic pathway.

OBJECTIVE To investigate the effect of hypoxia on the pharmacokinetic process of salidrosidein rats and to explore its underlying mechanisms. METHODS The Caco-2 cell monolayerwas exposed to 1% oxygen (O2) concentration for 24 h to build the hypoxiccell model. The transportation mode of salidroside was investigated with the aid of this hypoxia model by detecting the apparent permeability coefficient(Papp). Healthy Sprague Dawley (SD) rats were exposed to 9% O2 for 72 h for the construction of hypoxic rat model. Liver sample was subsequently collected from the hypoxic rats with an aim to identify enzymes responsible for salidroside metabolism. The expression levels of sali?droside-transporting and salidroside-metabolizing enzymes, including Sodium-dependent glucose cotrans?porters (SGLT1), β-glucosidase (GBA3)and sulfotransferase (SULT2A1), were thereafter detected by RT-PCR and Western blot. The metabolic activity of GBA3 and SULT2A1 was monitored by rat liver microsome incubation.In addition, the renal function of rats under hypoxia was assessed by detecting concentrations of blood urea nitrogen and creatinine. RESULTS The AUC and t1/2 values of salidroside in hypoxic rats were more than doubled, while the in vivo clearance was significantly reduced. Mechanistic study demonstrated that the PappA- B/PappB- A eualsto 10.3, indicating the potential active transport of salidrosile. The expression of SGLT1 and GBA3 was significantly decreased, which indicated a reduced metabolism of salidroside under hypoxia. Moreover, rat under hypoxia was found to suffer from renal dysfunction, with an abnormal value of blood urea nitrogen. CONCLUSION Due to the reduced metabolism and the abnormal renal function under hypoxia, the systemic exposure of salidroside in rats was signifi?cantly enhanced.

Objective To investigate the correlation between de nove anti-endothelial cell antibodies (AECA) and adverse events after renal transplantation and the effect of transplanted renal function within six months after operation.Methods The expression of AECA in serum of 85 renal transplant recipients was detected by indirect immunofluorescence assay (ⅡF) before and 1 day,3 days,7 days,15 days and 1 month after renal transplantation.The patients were divided into double positive group (AECA positive before and after surgery),single positive group (postoperative de nove AECA positive) and negative group (preoperative and postoperative AECA negative) according to AECA test results.The occurrence of adverse events in each group such as DGF,rejection,infection and so on,as well as the serum creatinine levels were recorded at each time point within six months.Results Of the 85 recipients,29 were positive for AECA,including 19 in the double positive group,10 in the single positive group,and 56 in the negative group.The incidence of rejection in single positive group (30％) was higher than that in the rest two groups (5.3％ for double positive group,and 17.9％ for negative group),but there was no statistically significant difference (P =0.21).The incidence of DGF in the single positive group,double positive group and negative group was 70.0％,26.3 ％ and 32.1 ％ respectively.The positive rate of the single positive group was significantly higher than that of the rest two groups (P =0.04),and the duration of DGF was significantly longer in the single positive group than that of the rest two groups (P＜0.01).The incidence of infection in the single positive group,double positive group and negative group was 20.0％,21.1％ and 8.9％respectively,and there was no significant difference among the three groups (P =0.31).As compared with the double positive group and the negative group,the serum creatinine level was significantly increased in the single positive group at 1st week,1st month,3rd month and 6th month after operation (P =0.02,P =0.04,P =0.04 and P =0.02 respectively).Conclusion Postoperative AECA can increase the risk of DGF,prolong the duration of DGF,and affect the recovery of renal function within 6 months after renal transplantation.

Objective To identify and rename one strain stored in National Center for Medicine Culture Collections ( CMCC) and used for tracheitis vaccine production. Methods The test strain CMCC (B)29108 and the type strain DSM30007T were cultured on NA medium. Characteristics in morphology, physiology, biochemistry and fatty acid profile were compared between the two strains. Phylogenetic analysis was based on 16S rRNA and rpoB gene sequences, together with the DNA-DNA hybridization assay. Results A Comparative analysis of a partial sequence of the 16S rRNA gene sequence revealed that the CMCC( B) 29108 strain was closed to the Acinetobacter species and showed the highest similarity with the type strain Acinetobacter baumannii DSM30007T. Moreover, the CMCC(B)29108 strain was highly similar to type strain DSM30007T in morphology, physiology, biochemistry and fatty acid profile. On the phylogenetic tree based on 16S rRNA and rpoB gene of all Acinetobacter members, the CMCC(B)29108 strain steadily clustered into one independent branch only with the DSM30007 T strain with a DNA-DNA hybridization value of 100%. Conclusion The CMCC(B)29108 strain that is one of the strains used for the production of tracheitis vac-cine should be assigned to the species of Acinetobacter baumannii based on its phenotypic, phylogenetic and chemotaxonomic characteristics.

OBJECTIVETo compare the therapeutic effects between the Hwato neuro and muscle stimulator (SXDZ-100) and the regular electronic stimulator (SDZ-II) on chronic functional constipation.

METHODSSixty-four cases of chronic functional constipation were randomly divided into a (SXDZ-100) observation group (n = 33) and SDZ-II control group (n = 31). For the SXDZ-100 group, under the considerations of patients' endurance, Zhigou(TE 6) and Tianshu (ST 25), Zusanli (ST 36) and Shangjuxu (ST 37) were punctured and then the courle of acupoints on the same side were connected with SXDZ-100 apparatus in reinforcing and reducing by twirling and rotating manipulation wave for 30 min, while in the control group SDZ-II apparatus was applied in the same way mentioned above with disperse-dense wave at frequency of 1Hz/20Hz for 30 min. By means of clinical therapeutic effect evaluation and clinical symptom score, the contrast between two groups can be made.

RESULTSAlthough the total effective rates were both 100.0%, the rate of short term effects in SXDZ-100 group (54.6%, 18/33) is significantly higher than that in SDZ-II group (29.0%, 9/31) (P < 0.05). After the treatment, the clinical symptom scores in both groups decreased significantly (both P < 0.05). And the therapeutic effective indices of the SXDZ-100 group were significantly higher than those of the SDZ- II group (P < 0.05).

CONCLUSIONThe therapeutic effect of Hwato neuro and muscle stimulator (SXDZ-100) on chronic functional constipation is superior to that of a regular electronic stimulator (SDZ-II).
