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 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 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 describe the profile of patients with infective endocarditis (IE) and assess prognostic factors of IE.Methods Clinical and etiology data of 218 patients with IE were collected retrospectively from January 2011 to January 2013.The distribution and antimicrobial susceptibilities of pathogens causing IE were evaluated.Prognostic factors associated with IE were determined by univariate and multivariate regression analysis.Results There were 148 men and 70 women with age of (46.0 ± 14.6)years.Ninety-five (43.6％) of them had heart diseases,including 72 cases (33.0％) of congenital heart disease and 23 cases (10.6％) of chronic rheumatic heart disease.Vegetations were detected by echocardiography in 171 (78.4％) patients.Microorganisms causing IE were identified in 84 cases (38.5％) cases.Streptococcus viridans was the dominant pathogen,accoumed for 63.1％ of all the pathogens,followed by Staphylococcus (13.1％) and Enterococcus (4.8％).Totally 7/11 Streptococcus viridans was susceptible to penicillin,while 100％ susceptible to the third and fourth generation cephalosporins,vancomycin and linezolid.One hundred and eighty cases underwent operations.The in-hospital mortality rate of IE was 3.2％.In univariate regression,health care-associated infection,prosthetic valve,anemia and chest symptoms (distress or pain) were related to the increased risk of mortality in patients with IE,while surgery appeared to be a protective factor.In the logistic regression model,the variables significantly associated with IE prognosis were health care-associated infection (OR =17.03,95％ CI 1.76-164.75,P =0.014) and anemia (Hb ＜ 90 g/L) (OR =13.47,95％ CI 2.46-73.60,P =0.003) and surgery treatment (OR =0.17,95％ CI 0.03-0.97,P =0.047).Conclusions Although Streptococcus viridans is the most common pathogen causing IE,the pathogens of IE become versatile.The antibacterial activity of penicillin against Streptococcus viridans is low.Health care-associated infection and anemia are risk factors of IE prognosis,while surgery treatment is a protective factor of severe IE.

Objective To evaluate the effects of propofol and sevoflurane anesthesia on cognitive function and amyloid beta protein ( Aβ) deposition in hippocampi of aged mice. Methods Thirty?six SAMP8 mice, aged 6 months, weighing 29-32 g, were randomly assigned into 4 groups ( n=9 each) using a random number table: control group ( group C ) , propofol anesthesia group ( group P ) , sevoflurane anesthesia group (group S) and propofol plus sevoflurane anesthesia group (group PS). In group P, propofol 140 mg∕kg was injected intraperitoneally, when righting reflex occurred, additional propofol 70 mg∕kg was given, and when it occurred again, additional propofol 40 mg∕kg was given. Group S continuously inhaled 1% sevoflurane for 120 min. Group PS continuously inhaled 2% sevoflurane for 120 min, and when righting reflex occurred, additional propofol 40 mg∕kg was given. Anesthesia was maintained for 120 min in P, S and PS groups. Before anesthesia and at 7, 14 and 28 days after anesthesia, Morris water maze test was performed, and the escape latency was recorded. Hippocampi were obtained to determine the expression of Aβ using immuno?histochemistry. Results Compared with group C, the escape latency was significantly prolonged at 7 days after anesthesia, and the expression of Aβwas up?regulated at 7, 14 and 28 days after anesthesia in group S, and no significant change was found in the parameters mentioned above in P and PS groups. Compared with the value at 7 days after anesthesia, the expression of Aβ was significantly down?regulated at 14 and 28 days after anesthesia in group S, and no significant change was found in the expression of Aβ at 14 and 28 days after anesthesia in C, P and PS groups. Conclusion Although sevoflurane anesthesia promotes Aβ deposition in hippocampi, it only causes short?term cognitive dysfunction, however, anesthesia with propofol or with propofol in combination with sevoflurane produces no influence in aged mice.

Objective To explore the rehabilitation for dysphagia in young patient after tracheotomy and cricopharyngeal achalasia with-out cough reflex. Methods A child was reviewed, who accepted tracheotomy after resection of cerebellar pilocytic astrocytoma for dyspha-gia. The features characterized as severe silent aspiration and failure of cricopharyngeus muscle relaxation. Therapies included Passy-Muir valve placement, breathing exercises, balloon dilatation, surface electromyography biofeedback, and electrical stimulation. Results The aspi-ration was observed when she drank thin liquid with weak cough reflex, and disappeared as eating thick liquid and paste food, with complete cricopharyngeus muscle opening, 7 weeks after treatment. She was removed the tracheotomy tube and nasal feeding tube 11 weeks after treatment, and got sufficient nutrition by fully oral intake. Conclusion The application of Passy-Muir valve and comprehensive swallowing training is helpful for patient post tracheotomy with silent aspiration in decreasing the risk of aspiration, improving cough reflex and prompt-ing swallowing function.
