This paper aims to establish a new method of calibration and positioning in quantitative analysis of multicomponents by single marker (QAMS), using Shuanghuanglian oral liquid as the research object. Establishing relative correction factors with reference chlorogenic acid to other 11 active components (neochlorogenic acid, cryptochlorogenic acid, cafferic acid, forsythoside A, scutellarin, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, baicalin and phillyrin wogonoside) in Shuanghuanglian oral liquid by 3 correction methods (multipoint correction, slope correction and quantitative factor correction). At the same time chromatographic peak was positioned by linear regression method. Only one standard uas used to determine the content of 12 components in Shuanghuanglian oral liquid, in stead of needing too many reference substance in quality control. The results showed that within the linear ranges, no significant differences were found in the quantitative results of 12 active constituents in 3 batches of Shuanghuanglian oral liquid determined by 3 correction methods and external standard method (ESM) or standard curve method (SCM). And this method is simpler and quicker than literature methods. The results were accurate and reliable, and had good reproducibility. While the positioning chromatographic peaks by linear regression method was more accurate than relative retention time in literature. The slope and the quantitative factor correction controlling the quality of Chinese traditional medicine is feasible and accurate.

Objective To evaluate the analgesic effect of oxycodone hydrochloride and morphine in preemptive analgesia for abdominal surgery.Methods The 200 patients who received abdominal operation were randomly divided into the oxycodone hydrochloride group (group O) and the morphine group(group M) with 100 patients in each group,and patients of the two groups were given oxycodone hydrochloride and morphine in preemptive analgesia respectively .The VAS, OAA/S and BCS 48 hours after surgery , the frequency of the use of PCIA in 24 hours,the satisfaction of patients ,and the occurrence rate of complications were compared between the two groups .Results There was no significant difference between the two groups in VAS ,BCS,OAA/S,frequency of the use of PCIA and patients satisfaction (P>0.05).The occurrence rate of nausea,vomit,and itch in group O were much lower than that in group M (P<0.05).The occurrence rate of drowsiness in group O was higher than that of group M(P<0.05).Conclusion Compared with morphine,oxycodone hydrochloride has the same analgesia efficiency and less side effect occurrence rate for patients with abdominal operation .

The abnormal expression of MUC15, a novel cell membrane-associated mucin, has been reported to predict poor survival in several cancers. The aim of the present study was to examine the expression of MUC15 in glioma and its correlation with clinicopathological features, including the survival of patients with glioma. The mRNA expression level of MUC15 was determined by RT-PCR, quantitative RT-PCR (RT-qPCR) and Western blotting in seven normal brain tissues and seven glioma tissues, respectively. The protein expression level of MUC15 was immunohistochemically detected in paraffin-embedded samples of 317 glioma tissues and 115 noncancerous brain tissues. The association of MUC15 expression levels with the clinicopathologic features and the prognosis was analyzed. The results showed that both mRNA and protein levels of MUC15 were significantly increased in glioma as compared with those in noncancerous brain tissue. Moreover, MUC15 overexpression was positively correlated with the advanced clinical stages of glioam patients (P<0.01). Furthermore, MUC15 expression levels were significantly correlated with the progression of glioma (P<0.001). Survival analysis indicated that glioma patients with higher MUC15 expression had a significantly shorter overall and 5-year survival time than those with low MUC15 expression. Multivariate analysis suggested that MUC15 overexpression was an independent factor for prognosis (hazard risk: 3.216; P=0.009). It was concluded that MUC15 is overexpressed in glioma tissues. Its overexpression correlates with tumor progression and it is a potentially unfavorable prognostic factor for patients with glioma.

Objective To re evaluate the diagnosis and outcome in patients with inflammatory bowel disease (IBD) by long term follow up at Wuhan University Zhongnan Hospital in Wuhan, China. Methods One hundred patients with ulcerative colitis (UC) and 15 with Crohn's disease (CD) treated in this hospital from 1980 to 1999 were re evaluated with the uniform diagnostic criteria proposed by National Workshop of Chronic Non infectious Intestinal Diseases, 1993. All patients were followed up by questionnaire, telephone and face to face interview 1～16 years after the initial diagnosis. Results Of 115 patients with IBD, 75(65%) were available for follow up study. Of 64 cases of UC, 46 had their diagnosis confirmed, 9 diagnosed as possible UC, and 9 cases were reclassified as other diseases. Of 11 cases with CD, 7 were diagnosed correctly, 2 were possible CD, and 1 were intestinal tuberculosis. In the remaining 55 UC, 3 died and 1 due to complication of UC. Other 52 UC, 37 had relapse. In the 10 patients with CD, 1 died due to complication. In other 9 cases 7 had relapse. In 46 patients with UC and 6 patients with CD there were symptom free or symptoms improved. Conclusions At follow up 1 to 16 years after the diagnosis of IBD, the initial diagnosis of UC and CD was confirmed in 86% and 82% respectively. Relapse rates of UC and CD were 71% and 78% respectively. The prognosis of patients with UC is better with 88% symptom free and improvement, while only 67% of patients with CD were symptom free and symptoms improved.
