The goal of the consensus initiated by the European Crohn’s and Colitis organisation(ECCO)was to establish the European consensus guidelines for surgical treatment of ulcerative colitis. The consensus covered four parts:the preoperative phase,intraoperative phase,postoperative phase and special situations. This consensus guideline was published in“Journal of Crohn’s and Colitis”and posted on the websites of ECCo in 2015. Interpretation of main points of this consensus was presented in this paper.

Objective:To explore diagnostic value of dynamic electrocardiogram (DCG) combined esophageal electro‐physiological examination (EEE) for sick sinus syndrome (SSS) .Methods :A total of 74 cases suspecting SSS ,who presented 24h mean heart rate <55 beats/min in DCG ,were selected .After DCG examination ,all subjects received EEE . Diagnostic value of single and combined examinations wereexplored .Results:Compared withthe SSS positive rate of single DCG and single EEE(87.8% ,86.5% ) ,theSSS positive rate ofDCG combined EEE(97.3% ) was sig‐nificantly rose ,P<0.05 both .Conclusion:Dynamic electrocardiogram combined esophageal electrophysiological ex‐amination can evaluate sinus node function from different angles ,which can significantlyincrease SSS diagnose rat .

Objective:To detect tenascin(TN) expressions and its effect in salivary gland tumor. Methods:The expressions of TN was examined in 8 chronic inflammations of salivary glands, 50 benign adenomas and 57 malign adenomas by Envision immunohistochemical technique. Results:Expression level of TN in the malign adenomas was higher than that in benign adenoma and chronic sialadenitis; higher in low differentiation than that in high differentiation and higher in lymphatic metastasis groups than that without lymphatic metastasis groups. No obviously difference was found between soakage inside the blood vessel and nerves and without soakage. Conclusion: TN might regulate cell attachment of epithelial cells in adenomas, and involve in adenomas' histogenesis and development.

Objective To investigate the diagnostic value of a double action MR contrast agent——gadobenate dimeglumine (Gd-BOPTA) for focal liver lesion and biliary system disease.Methods Articles about Gd-BOPTA in CNKI and PubMed for the past few years were searched and the value of Gd-BOPTA in the diagnosis of focal liver lesion and biliary system disease was summarized.Results For focal liver lesion,Gd-BOPTA not only can reveal blood supply of the lesion,but also reveal the hepatocellular functional status in the lesion.For biliary system,biliary excretion of Gd-BOPTA can be used to evaluate the anatomic structure of bile duct,function of gallbladder and biliary system disease.Conclusions Gd-BOPTA has an important value in the diagnosis of focal liver lesion and biliary system disease.Gd-BOPTA may have wider applications in the future.

Objective To investigate the chemical constituents of Polygala fallax.Methods The chemical constituents were isolated and purified via silica gel and Sephadex LH-20 column chromatography as well as recrystallization.Their structures were determined on the basis of spectral analysis and physicochemical properties.Results Six compounds were isolated and identified as 3-O?-D-glucopyranosyl senegenic acid(Ⅰ),tenuifolin(Ⅱ),presenegenin(Ⅲ),1,7-dimethoxy-2,3-methylenedioxy xanthone(Ⅳ),sinapinic acid(Ⅴ),ferulic acid(Ⅵ).Conclusion Compounds Ⅲ—Ⅵ are isolated from P.fallax for the first time.Compound Ⅰ is a new triterpenoid saponin,named fallaxsaponin A.

Objective To observe the change and relation between heart rate variability (HRV) and renin-angiotensin-aldostemne system (RAAS) under epidural anesthesia.Methods 16 cases patients ASAⅠ-Ⅱwere chose for epidural anesthesia.HRV,MAP and RT had been monitoring at pre-anesthesia (T1),15 min after inducing (T2),1 min after incising (T3),1 min pre-probing (T4),5 min after dragging uterus (T5), 1min after cutting uterus (T6) and the end point (T7).At same time,renin angiotensin and aldostemne were measured by drawing radial arterial blood when it was T1,T2,T3,T5,T7.Results Comparing with T1,LF/ HF increased significantly (P

Objective To study the changes of corneal sensitivity in diabetic and nondiabetic subjects after phacoemulsification. Methods This trial involved 42 diabetic subjects(42eyes)and 46 nondiabetic subjects(46 eyes)with cataract.All eyes were underwent phacoemulsification.Corneal sensitivities were tested before surgery and 1 day,1 week,1 month,3 month,6 month after surgery.Results The corneal sensitivity of diabetic subjects was greatly reduced at 1 day,1 week,1 month,3 month after surgery(P＜0.05),and returned to the preoperative values at 6 month(P＞0.05).The corneal sensitivity of nondiabetic subjects was reduced at 1 day,1 week,1 month af- ter surgery(P＜0.05),and returned to the preoperative values at 3 month(P＞0.05).The corneal sensitivity of diabetic subjects was lower than nondiabetic subjects before surgery(P＜0.05).The reduced range of corneal sensitivity in diabetic subjects was greater than that of nondiabetic subjects(P＜0.05).Conclusions The corneal sensitivity is decreased and the recovery is postponed after poacoemul- sification in diabetic subjects.

With the increasing frequency of international exchanges and cooperations,students from foreign countries,such as India and Pakistan,have come to our country for their higher degree education.We studied retrospectively and explored the teaching methods of Histology in English,and further provide our thoughts and viewpoints on improving the teaching qualities of foreign students.

Objective To discuss fluvastatin intervention on ventricular remodeling and plasma brain natri-uretic peptide( BNP) levels in dilated cardiomyopathy( DCM) .Methods 64 cases of DCM patients were selected and randomly divided into the intervention group and control group,each group in 32 cases.Both groups were treated with conventional drug therapy, including angiotensin-converting enzyme inhibitors,β-blockers, diuretics, etc.In conven-tional drug treatment intervention group based on the use of fluvastatin 40mg/d.Intervention in both groups before and 6 months after the intervention,plasma BNP levels were examined and ventricular remodeling indicators,analyzed and compared using Pearson Univariate correlation of each index.Results The total efficiency of the intervention group was higher than that of the control group(87.51%vs 65.63%,χ2 =4.730,P<0.05);6 months after the interven-tion groups,plasma BNP levels were significantly decreased left ventricular ejection fraction(LVEF),left ventricular end systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD) and relative wall thickness(RWT) were significantly improvements.BNP levels and LVEF and RWT was negatively correlated( r=-0.45,-0.39,all P<0.05);Positively correlated with LVESD and LVEDD showed(r=0.35,0.44,all P<0.05),the difference was statistically significant.Conclusion Fluvastatin intervention can significantly reduce plasma BNP levels in DCM and improve ventricular remodeling.
