The studies on Internet public opinions in domestic library and information field from 2004 to 2013 were analyzed by subject analysis,which showed that studies on the hot spots of Internet public opinions using bibliometrics and knowledge map were rather mature while studies on how library and information science provides the theoretical support for Internet public opinions in its service were immature. The problems in studies on Internet public opinions in library and information field should be further studied, including their objectives, theoretical support, techniques and application.

Objective To set up CEAP system for the diagnosis of portal hypertention.Methods Based on CEAP system from American Venous Forum,the clinical and pathologic classification of Budd-Chiari syndrome from Xu,the clinical and pathologic data of 251 cases of portal hypertension were analyzed retrospectively.Results According to the results of imaging examination [(Doppler ultrasound,percutaneous splenoportography,selective angiography of mesenteric artery,multi-slice spiral CT(MSCT) three dimensional(3D) reconstruction],clinical and pathological data,CEAP system for the diagnosis of portal hypertention was defined as follows: Clinical manifestation(C) including mild and severe types;Etiology(E)(congenital,primary,secondary);Anatomy(A) consists of liver,inferior vena cava,hepatic veins,and portal vein system;Pathophysiology(P) could have liver fibrosis/cirrhosis,obstruction,thrombosis,intrahepatic collateral circulation and tumors.Conclusions CEAP system for correct diagnosis,classification as well as the individual treatment is of great practical importance,and could be wide application.

OBJECTIVE To study drug resistance status of infected bacteria in abdominal surgical wound for their countermeasures. METHODS The abdominal surgical infection of a hospital was investigated from Jan 2000 to Dec 2004.Bacterial isolation and identification were carried out complying with National Operation Procedure of The Clinical Laboratory.Drug sensitivity test was performed with KB method. RESULTS The infection rate was 4.1%.The species were predominated by Gram-negative bacilli(71.1%),especially Escherichia coli(17.2%),Pseudomonas aeruginosa(16.7%) and Klebsiella pneumoniae(12.7%),and they all beared high antibiotics resistance. CONCLUSIONS Special attention should be paid to abdominal surgical wound infection.

Objective To investigate the diagnostic value of intraductal ultrasonography for the quality of biliary stricture.Methods Data of the patients who had received operation because of biliary stricture after IDUS examination from 2006 to 2010 were collected.IDUS results were compared with those of operation.Results There were 43 cases of malignant strictures and 6 benign strictures in total.The sensitivity,specificity,positive predictive value,negative predictive value and diagnostic accuracy of intraductal uhrasonography for the quality of biliary stricture were 97.7％ ( 42/43 ),83.3％ ( 5/6 ),97.7％ ( 42/43 ),83.3％ (5/6) and 95.9％ (47/49),respectively,which were significantly higher than conventional imaging like ultrasound B,CT and MRCP.Twenty one cases in 32 were diagnosed as malignant biliary stricture with cytological brushing,with the diagnostic accuracy of 65.6％.All cases had been diagnosed by IDUS.Conclusion Intraductal ultrasonography is of high diagnostic value for biliary stricture.However,cytological brushing based on IDUS is of limited diagnostic value for malignant biliary stricture.

Objective To study the influence of different time of lavipeditum with traditional Chinese medicine on recovery of gastrointestinal function right after cesarean section, to find the best lavipeditum time and improve the therapeutic effect of lavipeditum with traditional Chinese medicine. Methods 388 cases parturents after cesarean section were selected and were randomly divided into the observation group(200 cases)and the control group(188 cases)according to their bed number. The observation group began lavipeditum with Chinese medicine 6 hours after operation, and was scheduled 7:00-8:00 in the morning, 21:00-22:00 in the evening, lasted 20 minutes every time for consecutive 3 to 5 days. the control group started lavipeditum with Chinese medicine one day after operation, and continued lavipeditum any time they wanted. lasted 20 minutes every time for consecutive 3 to 5 days. Recovery of intestinal function were com-pared between the two groups. Results Postoperative recovery time of bowel sounds, anal exhaust time for the first time, the first defecation time, appetite and sleep quality three days after operation in the observation group were beuer compared with the control group. Conclusions Timing of lavipeditum with Chinese medicine is more effective for recovery of gastrointestinal function after cesarean section, it embodies the importance of time medicine and reach best aims.

Objective To investigate the relationships between the neck circumference and cardiovascular risk factors of middle-aged and elder people in a community. Methods Altogether 9 665 community residents ( age≥40 years) were enrolled in the present study. The height, weight, neck circumference, waist circumference, blood pressure, total cholesterol, triglycerides, low density lipoprotein-cholesterol ( LDL-C ) , high density lipoprotein-cholesterol ( HDL-C) , blood glucose, glycosylated hemoglobin, and fasting insulin were measured, and documented in the questionnaire along with other basic information. After adjusted for age, Pearson correlation coefficient was used to analyze the relationship between the neck circumference and the binary variables of cardiovascular risk factors. SPSS16.0softwarewasusedforstatisticalanalysis. Results (1)Theneckcircumferenceswere(37.11±2.79)cm in male and (32. 79 ± 2. 31) cm in female;which were higher in males than females. In both males and females, after adjusted for age, the neck circumference was positively correlated to waist circumference, body mass index, blood pressure, plasma glucose, LDL-C, triglycerides, and insulin resistance, the neck circumference was negatively correlated to HDL-C(all P<0. 05);The neck circumference of males was positively correlated to total cholesterol(P<0. 01);The neck circumference of females was not correlated with total cholesterol(P>0. 05). (2) After adjusted for body mass index and the waist circumference, the neck circumference of males increased with the risk of diabetes ( OR=1. 14, 95% CI 1. 02-1. 28);while the higher neck circumference of females increased the risk of hypertension (OR=1.17,95% CI1.08-1.27),diabetes(OR=1.24,95% CI1.13-1.37),dyslipidemia(OR=1.17,95%CI 1.09-1.27),andinsulinresistance(OR=1.15,95% CI1.06-1.26). Theneckcircumferenceexertedhigher impact on women than it did on men. Conclusion The neck circumference is associated with the cardiovascular risk factors. This association in females is stronger than that in males. The neck circumference seems to be an independent indicator for the cardiovascular risk.
