Objective To analysis the features of Montreal classification,serum markers,treatment and prognosis of Chinese patients with Crohn's disease(CD),and to estimate the relationships between clinical classification and anti-sarccharomyces cerevisiae antibody(ASCA),treatment and prognosis.Methods A retrospective study of 102 consecutive definite CD eases were performed and all subjects were classified into subtypes according to Montreal classification.The results of ASCA,extra-intestinal manifestation,treatment and disease behavior at follow-up were recorded and compared among different subtypes.Results The A2 subtype(52.9%)was dominated in Chinese CD patients.Ileocolon location(40.2%)and stricture lesion (53.9%)were common.The complication rate was dependent on disease course(P＜0.05),and intestinal fistula was associated with disease location(P=0.074).B1 subtype had higher progressive rate than B2 subtype(P=0.018).ASCA was not associated with disease loeation,disease behavior,treatment and disease progression(P＞0.05).Conclusions Crohn's disease mainly attack young people with male predominance.Early-onset CD patients have higher ASCA positive rate and disease progressive rate.The disease behavior progresses associated with disease course,and the rate of complication and the increase of surgery.The penetrating behavior is the main cause for surgery.Montreal classification is useful to predict the disease course,the need for surgery as well as the prognosis.

Objective To retrospectively evaluate the diagnostic accuracy of endoscopic ultrasonog raphy ( EUS) in pancreatic cancer, analyze the value of EUS in measurement of tumor diameters, TNM staging, and investigate the effectiveness of endoscopic ultrasonography-guided fine needle aspiration ( EUS-FNA). Methods All the data adopted from the patients underwent EUS in PUMC Hospital between 1997 and 2003. Eighty-eight patients with a final diagnosis of pancreatic cancer (56 is proven by surgical pathology, 10 by surgical findings and 22 by clinical diagnosis) and 47 patients with a final diagnosis of benign pancreatic disease were included and analyzed. Results The sensitivity, specificity, accuracy, positive and negative predictive values of EUS in the diagnosis of pancreatic cancer were 95. 5% , 59. 6% , 83. 0% , 81. 6% and 87. 5% respectively. Tumor diameters measured by EUS (2. 8?1. 0)cm were obviously smaller than those by surgical findings (6.5 ? 2. 9) cm. For TNM stage, compared with surgical findings, the accordance rates of EUS in T and N staging were 43. 1% and 61. 1% respectively. The accuracy of EUS-FNA in the diagnosis of pancreatic cancer was 76. 5% ( 13/17). Conclusions The sensitivity of EUS in pancreatic cancer is highest among all imaging procedures. Tumor diameters measured through EUS are smaller than those by surgery.

Objective To investigate the effects of nicardipine on apoptosis in ischemia?reperfusion myocardium of rabbits. Methods Forty New Zealand rabbit were randomly divided into 4 groups:control group(group A),ischemia group(group B),ischemia?reperfusion group(group C),ni?cardipine treatment group(group D). Ischemia?reperfusion model was established by left circumflex branch coronary artery ligation for 40 min,fol?lowed by 120 min reperfusion. Apoptotic cardiomyocyte was detected using the analysis for the exposure of phosphatidyl?serine ( Annexin V)meth?od. Results Myocardial cell damage was lower in D group than that in group B and group C from pathology(P<0.01). The myocardial cell apopto?sis in group D is less than that of group B and group C(P<0.01),but higher than that of group A(P<0.05). Myocardial cell necrosis is lower than group B and group C(P<0.01),and no difference was found comparing with group A(P>0.05). Conclusion Nicardipine horizon can reduce the myocardial cell apoptosis in rabbits with myocardial ischemic reperfusion injury.

20 cup-years) were found to have increased risk for pancreatic cancer (OR 3.681; 95%CI 1.604～8.443). Daily diet with high meat intake was also linked to pancreatic cancer. About 18.49% of the pancreatic cancer patients had diabetes mellitus compared to the control group of 5.77% (P=0.0003). Typical symptoms of pancreatic cancer were anorexia, upper abdominal pain, bloating, jaundice and weight loss. The high risk score of the two groups were 80.6 (95% CI 74.9～86.3) and 7.4(95% CI 6.0～8.7) (P

Objective To evaluate the value of intraduetal ultrasonography (IDUS) in diagnosing biliary and pancreatic disorders. Methods The findings by endoscopic retrograde cholangiopancreatography (ERCP) and IDUS from 19 patients with suspected biliary and pancreatic disorders from July 2006 to August 2007 in our hospital were analyzed retrospectively. Results Of the 19 patients, 17 had obstructive jaundice (including 6 eases of cholangiocarcinoma, 2 pancreatic adenocareinoma, 2 gallbladder carcinoma, 2 chole-docholithiasis with bile duct stricture, 2 autoimmune pancreatitis, 1 papillary adenocarcinoma, 1 papillary adenoma, and 1 sclerosing cholangitis) and 2 intraduetal papillary mueinous tumor (IPMT). The diagnosis was confirmed by surgery and pathological findings in 11 patients. The diagnostic accuracy of ERCP and IDUS was 73. 7% (14/19) and 84. 2% (16/19), respectively, and that of ERCP combined with IDUS was 89. 5% (17/19). The sensitivity and specificity of ERCP to differentiate benign bile duct strictures from ma-lignant ones were 100. 0% (11/11) and 83.3% (5/6), respectively; and those of IDUS were 100. 0%(11/11) and 100. 0% (6/6), respectively. The sensitivity and specificity of ERCP in diagnosing cholan-gioeareinoma were 83.3% (5/6) and 60% (3/5), respectively; and those of IDUS were 100. 0% (6/6) and 40. 0% (2/5), respectively. Conclusion Combination of ERCP with IDUS can improve the diagnostic accuracy of pancreaticobiliary disorders. Additionally, IDUS shows higher sensitivity and specificity in differ-entiation between benign and malignant bile duct strictures, but it is still difficult to identify the etiologic factors of malignant bile duet strictures by IDUS.

Objective To analyze the characteristics of somatotypes of South Asian type, North Asian type and East Asian type, and to compare the main differences among them. Methods The characteristics of somatotypes among South Asian type, North Asian type and East Asian type in 29 Chinese Mongolian ethnic groups were compared by using the Heath-Carter anthropometric somatotype. The reasons for differences of South Asian type were that North Asian type were analyzed by using principal component analysis. Results The male groups of North Asian type were endomorphic mesomorph and the South Asian types were balanced mesomorph, while the East Asian types differed greatly from each other.The female groups of North Asian types and the East Asian types were mesomorphic endomorph and the South Asian types were endomorphic mesomorph. The somatotypes of East Asian types were similar to North Asian types but were greatly different from South Asian types.Principal components analysis showed that the main differences between South and North of male groups lied first in ectomorphy and then in endomorphy.The differences between female groups of South and North were mainly on endomorphy. Conclusion The ethnic group of North Asian type is higher than South Asian type in endomorphy but lower in ectomorphy.

Objective To explore the clinical effect of patients of oral and maxillofacial space infection treated with improved closed negative pressure drainage combined with hyperbaric oxygen, and the possibility of using this method to decrease the hospital expenses. Methods 156 patients with oral and maxillofacial space infection were divided into control group, closed negative pressure drainage group and improved closed negative pressure drainage combined with hyperbaric oxygen group by random number table. 52 patients in each group. The granulation tissue growth time, the healing of wound, clinical effect of the 8thday, hospitalization days, wound healing time, antibiotic cost, average cost in hospital were recorded after treatment. Results The average wound healing time of patients in improved closed negative pressure drainage combined with hyperbaric oxygen group was(6.06 ± 0.23)days, while the granulation tissue growth time was(16.13 ± 2.89)days, both of them were much shorter than the control group[(15.46 ± 4.68)days and(28.60 ± 3.50)days respectively],as well as the closed negative pressure drainage group [(7.43 ± 0.75) days and (22.67 ± 4.34) days respectively], and the differences were statistically significant which the F values equaled to 6.213 and 8.451, P values all less than 0.05. The total healing rate of patients in closed negative pressure drainage group and improved closed negative pressure drainage combined with hyperbaric oxygen group were both 100.00%(52/52), the difference was statistically significant compared with control group (χ2=6.89, P<0.05). The average hospitalization days of the patients in the closed negative pressure drainage group and improved closed negative pressure drainage combined with hyperbaric oxygen group were (8.20 ± 1.49) days and (7.45 ± 0.42)days, the antibiotic cost were(5 068.34 ± 1 074.68)RMB and (5 001.00 ± 456.00) RMB, the average total cost were (9 457.43 ± 647.23)RMB and (9 249.00 ± 367.00)RMB, all these indexes were much lower that which in control group[(18.40 ± 5.89)days,(21 000.43 ± 2 036.48) RMB and (31 000.66 ± 2 711.36) RMB], and the differences were statistically significant, F values equaled to 15.221, 29.434 and 81.220 each, P values were all less than 0.01. Conclusions Improved closed negative pressure drainage combined with hyperbaric oxygen method could improve the clinical effect of patients with oral and maxillofacial space infection, speed up the granulation tissue, shorten the in-hospital time as well as reduce the medical cost.

Objective To evaluate the value of clinical data and various methods of diagnostic imaging in the patients with pancreatic cancer. Methods Two hundreds and fifty-six patients with pancreatic cancer admitted into Peking Union Medical College Hospital between 1996 and 2004 were included. The clinical symptom and the accuracy of various imaging methods (B-US, CT, ERCP, EUS, DSA and MRI) in assessing pancreatic carcinoma were analyzed. Results Weight lost was the most common symptom in 79% of patients with pancreatic carcinoma. Jaundice was mostly seen in patients with pancreatic head carcinoma. Upper abdominal pain was in 86% of patients with carcinoma in pancreatic body and tail. The diagnostic accuracies of B-US, CT, ERCP, EUS, DSA and MRI were 83% , 89% , 90% , 91% , 82% and 79% respectively. Conclusion B-US and CT scanning should be undergone in patients with abdominal pain, jaundice and weight lost who were suspected to have pancreatic carcinoma. Further imaging techniques such as EUS, ERCP and MRI should be advised in patients highly suspected to have pancreatic carcinoma, in spite of the results of B-US and CT were negative.

[Objective] To observe the inhibitory effect of acupuncture combined with herbal medicine on hyperplasia of mammary glands in rats. [Methods] Rats were randomized into 6 groups: A (normal) , B (model) , C (acupuncture) , D ( herbal medicine), E (acupuncture combined with herbal medicine) and F (triphenyloxamine) . Rat models of hyperplasia of mammary glands in Group B, C, D, E and F were established by intramuscular injection of estradial benzoate and progesterone. Nipple height in rats were detected before and after treatment. The number of acini in each lobule, the diameter of acinar cavity and duct in the second pair of mammary glands were calculated under light microscope. The expression of estrogen receptor (ER) and progesterone receptor (PR) in the tissues of mammary gland were examined by immunohistochemical method after treatment. [Results] Nipple height in group B was more than that in group A and the scores of ER and PR expressions were also higher (P
