Objective To observe the clinical efficacy of small-dose ranitidine hydrochloride and diphenoxy- late compositae in the combined treatment of diarrhea-predominant irritable bowel syndrome(D-IBS).Methods A prospective,randomized controlled clinical trial was designed.150 D-IBS patients according to RomeⅡcriteria were randomly divided into combined treatment group and control group.The combined treatment group(74 patients)re- ceived ranitidine hydrochloride,0.15g,each evening and diphenoxylate compositae,1 piece,each evening.The control group(76 patients)received diphenoxylate compositae,1 piece,rid.This study consisted of a 2-week baseline period, a 3-week treatment period,followed by a 2-week follow-up period.The main efficacy variable was assessed by per- ception of overall symptom during the previous weeks.Secondary efficacy variables included severity of diarrhea,ab- dominal pain and distention and other symptoms.Results After treatment of 3 weeks,the efficacy of the combined treatment group was better than that of the control group(x~2=5.10,P

Objective:To study the clinicopathological features of mixed epithelial and stromal tumor of the kidney(MESTK). Methods:Clinical and pathological characteristics of one case of MESTK was stu-died. Results:A case of MESTK which uncommonly occurred in a 16-year old adolescent male presented with dysuria and a large mass in the right renal region without a history of estrogen/progestogen treatment and/or obesity or urogenital surgery. Radiology revealed a large cystic/solid mass within the right kidney. Grossly, it was well demarcated and had a solid and cystic appearance on sectioning. Microscopically, the tumor was composed of a mixture of stromal and epithelial components. The epithelial component was composed of flat to columnar cells forming glands or tubules. The stromal components essentially consisted of bland, loosely packed spindle cells in an edematous and myxoid background. In some areas, there were smooth muscle cells forming bands and fascicles but no ovarian-type stroma was present. Immunohistochemical staining revealed that the epithelial components were positive for AE1/AE3 and focally positive for estrogen receptor(ER),progesterone receptor(PR), CD10 and Vimentin, whereas the stromal components were positive for ER, PR, Desmin and smooth muscle actin(SMA). Both epithelial and stromal components were negative for HMB-45, S-100,?-inhibin and WT-T. Five months after resection, the patient was well without evidence of recurrence. Conclusion:MESTK occurred in a pubertal male, as in the current case, supports the hypothesis that proliferation of remnants of the primitive mesenchyme in the kidney in situation of sex-steroid abnormity may play an important role in the pathogenesis of male MESTK.

AIM To study the influence of chronic stress on the level of CNTF and CNTF mRNA in hippocampal neurons of rats. METHODS The chronic stress model was established by chronic unpredictable mild stress, openfield test was performed to detect the behavior of rats. Immunohistochemistry and in situ hybridization were used to observe the level of CNTF and CNTF mRNA. RESULTS Compared to control group, the CNTF like immunoreactivity and signals of CNTF mRNA in situ hybridization in the hippocampal neurons of chronic stress group were significantly decreased. CONCLUSION These results show that chronic stress can significantly decrease the level of CNTF and CNTF mRNA in the hippocampal neurons of rats.

Objective To explore the blood-saving and conservation effect and clinical prognosis of extracorporeal circulation circuits designed individually by using medical polymeric materials for adults and infants in cardiac surgical procedures.Methods A total of 41 new extracorporeal circulation circuits designed based on the operation requirements,including 20 for adults and 21 for infants,were applied on adults and infants (body weight less than 10 kg),and the results were compared with that of the conventional circuits on adults (20) and infants (19)respectively.Total priming volume,priming and intraoperative blood products consumption,pump pressure,intraoperative blood hemoglobin (Hb) level,free Hb (f-Hb),platelet (Plt) count,mixed venous oxygen saturation (SvO2),colloid osmotic pressure (COP),lactate (Lac) level,Hb level after modified ultrafiltration,endotracheal intubation time and ICU time were all collected in two groups.Results Priming volume,priming and intraoperative blood consumption and f-Hb level in the blood-saving and conservation circuits group were significantly lower than that of conventional circuits group (P＜0.05).There were no significant differences (P＞0.05) between the two groups in pump pressure,intraoperative blood Hb level,Plt,SvO2,COP,Lac level,Hb level after modified ultrafiltration,endotracheal intubation time and ICU time.Conclusions The minimized blood conservation extracorporeal circulation circuit plays an important role in reducing priming volume and blood transfusion.It maintains a normal level of hemodynamics,oxygenation and tissue perfusion level during cardiopulmonary bypass in cardiac surgery for adults and infants.Red blood cell destruction can be reduced by improving blood compatibility,and physical data are all stabilized intra and post operation.This new circuit is secure,with its better outcome,expected in application.

Objective:To observe the clinical efficacy of morpholine nidazole in the treatment of infection after radical resection of perianal abscess.Methods:Thirty patients diagnosed with perianal abscess were randomly divided into the observation group(given intravenous infusion of morpholine nidazole) and the control group(given intravenous infusion of ornidazole).Results:There was no significant difference in postoperative wound infection rate between the observation group and the control group ( P>0.05). There was significant difference in wound healing quality between the two groups on the 2 d and 7 d after the operation ( P<0.05). There was no significant difference in WBC and neutrophil counts between the two groups ( P>0.05), and the WBC and neutrophil counts in the two groups were significantly lower on the 7th day after the operation than before the treatment, and the observation group was significantly lower than the control group ( P<0.05). After treatment, there was no significant difference in the clearance rate of escherichia coli, klebsiella pneumoniae, bacteroides fragile and staphylococcus aureus in the observation group ( P>0.05), but there was significant difference in the overall bacterial clearance rate compared with the control group ( P<0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group ( P<0.05). Conclusions:The use of morpholinidazole in patients with perianal abscess is effective and safe.

OBJECTIVETo investigate the impact of hepatic steatosis on virologic response in chronic hepatitis B (CHB) patients treated with pegylated interferon-alpha (PEG-IFNa).

METHODSNinety-six naive patients positive for hepatitis B e antigen (HBeAg) and with biopsy-proven CHB were administered PEG-IFNa-2a or PEG-IFNa-2b for 48 weeks. Virologic response (HBeAg clearance and hepatitis B virus (HBV) DNA less than 5 log10 copies/ml) and biochemical response (alanine transaminase (ALT) normalization) were compared between patients with (n=34) and without (n=62) steatosis.

RESULTSThe HBV DNA titer in the steatosis group was significantly lower than that of the non-steatosis group (6.961.27 vs. 7.541.28 log10 copies/ml; t=2.161, P=0.033). After 48 weeks of PEG-IFNa treatments, there was no significant difference in HBeAg seroconversion or the percentage of undetectable HBV DNA (less than 3 log10 copies/ml) between steatosis and non-steatosis patients. However, the steatosis patients presented with a significantly lower complete response rate (virologic response plus biochemical response) compared to non-steatosis patients (26.5% vs. 48.4%; x² =4.373, P=0.037). Of the 45 CHB patients with undetectable HBV DNA after 48 weeks of treatment, seven did not achieve ALT normalization. The rate of patients with non-biochemical response was significantly higher in the steatosis group than in the non-steatosis group (33.3% vs. 6.67%; P=0.032).

CONCLUSIONHepatic steatosis does not affect the virologic response, but does affect the biochemical response in CHB patients treated with PEG-IFNa for 48 weeks.
