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 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 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 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 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.

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 By studying the change of the special antibodies titer IgG, IgM and nucleocaspid to SARS corona virus in family clustering cases , searching and testing the special antibody to SARS corona virus in the patients kinfolks Method Testing special antibody titer to SARS corona virus of 14 patients from 5 different families and their 10 kinfolks continuously by IFA and antigen capturing ELISA methods, taken samples in the 7 th , 14 th , 30 th , 60 th , 120 th , 180 th , 210 th ,270 th ,360 th day after SARS patients infected by SARS corona virus, dilute them, and then measure titers of three kinds of antibodies ResultsDuring the testing of IgG antibody titer of the 14 SARS patients by IFA method, in the 120 th day, the average titer is up the highest value, it is 1/1 120; in the 180 th day, the average titer begins to descend, it is 1/262 in the 360 th day, the average titer is 1/71 During the testing of IgM titer, the average titer is 1/32, it is obviously lower than it in IgG testing; the IgM titer of the most SARS patients are disappear after 120 days The average value of nucleocaspid antibody titer is lower than it in IgG antibody But there are some differences in 5 cases While IgG antibody titer begins to descend in the 180th day, nucleocaspid antibody titer begins to ascend obviously, it is up to 1/790 210 th day begins to descend In the meantime, we have tested special antibody to SARS corona virus of their 10 kinfolks (include 2 children) who have contacted with SARS patients closely The samples are taken in the 14 th , 30 th , 60 th day, and all the special IgG, IgM and nucleocaspid antibody to SARS corona virus are negative ConclusionBy testing the special IgG antibody to SARS corona virus of the 14 family clustering cases ,we find the special IgG antibody titer of the SARS patient is higher, and it can remain for a long time As for the nucleocaspid antibody titer of some SARS patients ascend obviously after 180days, we think that it provide useful information for vaccine development and it is necessary for us to study more in the clinic There is no special blood serum antibody to SARS corona virus in their 10 kinfolks of the SARS patients

Objective To investigate the indication,feasibility and clinical effectiveness of stage management of Budd-Chiari syndrome(B-CS). Methods From Feb 2007 to June 2009,32 cases of Budd-Chiari syndrome(9 cases of type Ⅰ,17 cases of type Ⅲa,6 cases of type Ⅲ b)were admitted.Inferior vena cava hypertension(IVCHT)and portal hypertension(PHT)co-existed in all the patients.According to the clinicopathologic classification and hemodynamic compensation,these patients underwent single stage treatment(snrglcal procedure or radioactive intervention)or two-stage management(one.stagesurgical procedure/radioactive intervention plus two-stage surgical procedure/radioactive intervemion).Results Recovery was achieved in all patients without mortality.The main complications were Dleural effusion in 3 cases,acute heart failure in 2 cases and celiac lymphatic leakage in 1 case respectively.which were cured after medical treatment.In 4 months to 2 years follow-up,no recurrent cases were identified and all the patients were in good condition. Condusions Stage management of Budd.Chiari svndrome canalleviate the perioperative risk and clinical effectiveness can be achieved.The hemodynamic compensation is the basis on which stage management is adopted.

Background Researches determined that the pathogenesis of retinal vein occlusion (RVO) is associated with primary open angle glaucoma (POAG) in Caucasian population.However,the relationship between RVO and POAG in Asian population is unclear.Objective This study was to survey the percentage of POAG in RVO patients in China.Methods A prospective cross-sectional observational study based on hospital was performed.Three hundred and seventy five patients with newly diagnosed RVO by fluorescein fundus angiography (FFA) were consecutively enrolled in Peking University Third Hospital from October 2011 to May 2013,and gonioscopy was carried out in all the patients.Glaucoma was diagnosed according to the criteria of the International Society of Geographical and Epidemiological Ophthalmology (ISGEO).RVO was classified into central retinal vein occlusion (CRVO),hemicentral retinal vein occlusion (HRVO) and branch retinal vein occlusion (BRVO) based on fundus photograph and FFA,or classified into arteriovenous crossing RVO (AV-RVO),optic cup RVO (OC-RVO),optic nerve RVO without optical nerve head swelling (NONHS-RVO) and RVO with optical nerve head swelling (ONHS-RVO) based on the sites of venous occlusion.The percentages of POAG in different types of RVO were calculated.This study was approved by Ethic Committee of Peking University Third Hospital,and written informed consent was obtained from each patient before entering study cohort.Results Three hundred and seventeen RVO patients finished screening of glaucoma,with the response rate 84.5％.The percentage of POAG is 8.2％ in RVO patients,including 7.1％ in the CRVO patients,23.5％ in HRVO patients and 6.2％ in BRVO patients.The percentage of POAG was significantly higher in OC-RVO patients (27.9％) and NONHS-RVO patients (13.2％) than that in AV-RVO patients (4.7％) and ONHS-RVO patients (1.3％) (all at P＜0.05).Conclusions The overall percentage of POAG in RVO patients in China is 3-4 times higher than general population.Higher percentage of POAG is found in OC-RVO patients and NONHS-RVO patients,suggesting that pathogenesis of RVO is probably associated with the glaucomatous anatomic changes of optical nerve head.

Objective To investigate the relationship of parity and other reproduction-associated factors with metabolic syndrome(MS) in middle-aged and elderly women in Nanchang community.Methods Female permanent residents over 40 years old were sampled for a routine examination and a questionnaire survey covering basic information,5 894 subjects were enrolled and identified as effective cases.MS was diagnosed according to the standard of China Diabetes Society in 2004.Factors including age,education,profession,marital status,parity,child-bearing history of macrosomia,breastfeeding,menarche age,and menopausal age were analyzed in order to find their relationship with MS.The univariate logistic analysis was followed by binary logistic regression analysis if P＜0.05,and OR value and confidence interval were calculated.Results Univariate logistic regression analysis showed that age,education,profession,parity,breastfeeding,and menopausal age were influencing factors of MS (all P ＜ 0.05).There was no correlation to marital status,miscarriage history,child-bearing history of macrosomia,menarche age with MS(all P＞0.05).Binary Logistic regression analysis showed that the risk of MS increased with age:OR =1.51 (95 ％ CI 0.98-2.32) during 50-59 years,OR =2.10 (95 ％ CI 1.34-3.30) during 60-69 years,and OR =2.63 (95 ％ CI 1.61-4.31) in cases aged over 70 years,as compared to the group aged 40-49 years.The risk in non-manual workers increased about 34 percent OR =1.33 (95 ％ CI 1.04-1.70),compared with manual workers.The risk of MS increased with parity,being OR =1.46 (95％ CI 1.14-1.88),OR =1.78 (95％ CI 1.30-2.43),and OR =1.84 (95％ CI 1.24-2.72),with 2,3,and 4 child-bearings respectively as compared to cases with only one childbearing.The risk of MS was reduced with advancing menopausal age being about 6 percent reduction with each increased year of menopausal age(OR =0.94,95％ CI 0.90-0.99).There was no difference between education,breastfeeding and MS(P＞005).Conclusion Multiple parity,earlier menopausal age,less manual work,and aging seem to be the risk factors of MS in women.
