Objective To assess the effects of tegaserod on rat with visceral hypersensitivity. Methods Neonatal SD rats were randomized to receive colonic acetic acid irritation between postnatal days 8 and 21 as visceral hypersensitive model (Group H) or by saline intrarectally as control group (Group C). While rats were grown-up, rectal distention (RD) was performed by a balloon rapidly inflated with increasing volumes of saline (0.4, 0.8 and 1.2 ml) for 20 seconds at five-minute intervals. The 5 subgroups of Group H were injected randomly with saline, vehicle (1-methyl-2-thpyrrolidone) or tegaserod at doses of 0.1, 0.3 and 1 mg/kg i.p., respectively. The 2 subgroups of Group C were injected with saline or tegaserod at dose of 1 mg/kg i.p.. RD was performed 10 min after injection and abdominal withdrawal reflex (AWR) was recorded, and then c-Fos expression in spinal cord (L6-S1) was analyzed quantitatively by immunohistochemistry. Results 1) Compared to saline, vehicle did not affect AWR and c-Fos expression. 2) Compared to saline, tegaserod significantly (P

Objective To evaluate the therapeutic efficacy and side effects of cyclopnosphamide, adriamycin, cisplatin (CAP) or CAP combined with verapamil(VPL) in chemotherapy of patients with advanced lung adenocarcinoma. Methods A total of 56 patients(male: 27, female: 29, average age: 48 years old, age range: 32-78 years old) with stage Ⅲb/Ⅳ lung adenocarcinoma confirmed pathologically from April 1998 to December 2001 were divided into two groups: group A(30 patients), treated with cyclophosphamide (CTX, 600 mg?m -2 ?d -1 ) on days 1 and 8, adriamycin (ADM, 40 mg/m 2) on day 1, and cisplatin (CDDP, 30 mg?m -2 ?d -1 ) on days 1, 2 and 3 and group B(26 patients), treated with the same dose of CTX, ADM and CDDP and an additional oral VPL treatment (60 mg t.i.d . on days 1-7). Each of the 3 cycles was repeated every 21 days. Results The patients in group A had a lower response rate (26.7% vs 38.5%, P

Objective To investigate the accumulation of liver bile acids and bile acid regulated nuclear receptor farnesoid X (FXR) and its target gene cholesterol 7α hydroxylase (Cyp7α1) and small different dimer partner (SHP) in normal rats during pregnancy and lactation .Methods SD rats were maintained in the SPF‐grade facilities for time‐controlled mate .Livers were collect‐ed at Gestation Day (GD) 10 ,14 ,and 19 and Postnatal Day (PND) 1 ,7 ,14 and 21 d .Hepatic bile acids were quantified with a total bile acid assay kit ,and mRNA expression of FXR ,Cyp7α1 and SHP was determined by RT‐PCR .Western blot was used for Cyp7α1 protein quantification .Results In livers of normal rats ,bile acids was not elevated during pregnancy but was increased during lacta‐tion .The bile acid synthesis rate limiting enzyme Cyp7α1 increased during lactation but were normal during pregnancy .SHP was 6 fold higher at the late pregnancy ,and slightly higher during lactation .FXR was increased at postpartum .Conclusion Under normal circumstances ,hepatic bile acid synthesis during pregnancy was controlled by SHP feedback ,while during lactation ,hepatic bile acids increased ,along with increased Cyp7α1 and FXR .

Thebasic ideas for developingChinese herbal specimens databaseand its specific processes were described, the problems in its development were pointed out with measures put forward for their solution.

Objective To observe the effect of therapeutics of invigorating spleen and kidney, removing blood stasis and clearing away turbidness on lipid metabolism and renal function in patients with chronic renal failure (CRF). Methods Fifty-eight patients with CRF were randomly divided into the treated group (30 cases) and the control group (28 cases). Both groups were treated with low-protein diets, controlling hypertension and symptomatic treatment. And Chinese drugs for invigorating spleen and kidney, removing blood stasis and clearing away turbidness were given additionally to the treated group. The curative effect, renal function and lipid metabolism were observed after two months. Results TC, TG and APOB in the treated group lowered significantly, HDL-C and APOAⅠraised significantly after treatment (P0.05). The total effective rate and the improvement of renal function in the treated group were better than those in the control group (P

Objective To observe the effect of the therapeutics of warming Yang and inducing diuresis with removing blood stasis and clearing away turbidness in retarding the course of chronic renal failure (CRF). Methods Sixty-five patients with CRF were randomly divided into the treated group (33 cases) and the control group (32 cases). Both groups were treated with low-protein diets,controlling hypertension and symptomatic treatment. And Chinese drugs for warming Yang and inducing diuresis with removing blood stasis and clearing away turbidness were given additionally to the treated group. The time (month) for doubling serum creatinine (SCr) level was taken to evaluate the speed of CRF progression. Results In the treated group,the time for SCr increased from (300.5?99.2) ?mol/L to (602.0?199.6) ?mol/L was (27.6?9.1) months,while in the control group,the time for SCr increased from (296.3?96.8) ?mol/L to (598.8?198.4) ?mol/L was (17.2?5.7) months. Comparision between the tow groups showed significant difference (P

Objective To explore the relationship between angiogenesis and ischemic neurological deficit repair through exogenous interventions,and investigate optimal intervention routes for angiogenesis in cerebral ischemia rats.Methods Totally 240 SD rats were randomly divided into sham operation group,ischemic control group,ischemia and vascular endothelial growth factor(VEGF) group [1 653.3 ng/(g?d),i.p.,for 10 d],ischemia and endothelial progenitor cell transplantation(EPCs) group(2?1010/L,10 ?l),ischemia and anti-VEGF monoclonal antibody group [3 mg/(kg?d),i.p.,for 10 d].Cerebral microvessel density,somatosensory evoked potentials(SEP) and motor evoked potentials(MEP) and behavior were observed in 1,3,7,14,30 and 60 d after injury.Results New blood vessel density of ischemia and VEGF group,ischemia and EPCs group were significantly higher than ischemic control group in all time points besides 1 d after injury(P

Objective To explore effective precautions and interventions for choking in dysphagia patients.Methods Clinical data on f dysphagia patients hospitalized from September 1,1996 to Aug 8,2014 were retrospectively analyzed to correlate choking with gender,age,consciousness,type of aspiration,food-intake pathway and food texture.Results Only 0.17％ of the patients (n =8) were found to have choked,and 6 of them were men.Children,teenagers,the middle-aged and the aged constituted 25％,12.5％,37.5％ and 25％ of the patients respectively.75％ were conscious and 62.5％ displayed silent aspiration.6 cases used oral intake and 2 used nasogastric tube feeding.Among the 8 choking patients,half ate solid food,2 semisolid and 2 liquid food.Six survived and 2 died.Conclusion The risk factors for choking include silent aspiration and oral intake of solid or semisolid food.The successful rescue rate for choking is relatively low,so clinicians should be aware of and try to eliminate these risk factors.

OBJECTIVE To compare the difference of Pseudomonas aeruginosa(PAE) biofilms formation in different conditions including incubated time,temperature,attaching materials,and flowing speed.METHODS PAE biofilms were established in a chemostat-coupled MRD and detected with the method of viable bacteria counting.The number of CFU/disc was measured in different culture time(8h,24h or 72h),different temperature(23℃ or 37℃),different adherent materials(glass or silicone),different flow velocities(30ml/h or 90ml/h) and different culture media(M63 medium,M-H croth or LB broth).RESULTS Keeping the other conditions invariable,the log10CFU/disc of viable bacteria in 8h,24h or 72h biofilms were 4.01?0.26,4.59?0.49 or 5.20?0.47,respectively(P
