Objective To compare the success rate, the one-time success rate, the average required time and the incidence of complications of two methods in oronasal conversion of nose biliary duct in naso-biliary drainage. Methods 60 cases of patients with ENBD in the ERCP in our department from March,2008 to March, 2010 were divided into the study group and the control group by random. The patients with sleeving the gastric tube by the guidewire during oronasal conversion of nose biliary duct were considered as the study group, and the patients using the traditional method were considered as the control group. The success rate of sleeving gastric tube, the one-time success rate of grasping, the average required time and the adverse reactions of the two groups were compared. Results The success rate of the study group was 100%, and the control group was 90%, there was no statistical significance. The one-time success rate of the study group was 76.7%, higher than 46.7% of the control group. The average required time of the study group were (1.3±0.3) min, shorter than (5.1±0.7) min of the control group. The incidence of complications in the study group were 13.3%, lower than 93.3% of the control group. Conclusions To sleeve the gastric tube by the guidewire can increase the one-time success rate of grasping the gastric tube, shorten time of grasping the gastric tube and significantly reduce discomfort of patients.

Inhibitor of growth (ING) family proteins belong to candidate tumor suppressor proteins. The ING proteins participate in PtdInsPs-mediated lipid signaling and hormone signaling pathways. They are associated with histone acetyltransferase, histone deacetylase and play a role in chromatin remodeling and gene transcription regulation. ING proteins regulate cell growth, apoptosis and DNA damage repair in p53 dependent manner; thus linking the processes of cell cycle regulation, apoptosis and cellular aging through epigenetic regulation of gene expression.

Objective: To investigate the awareness of knowledge about HPV infections and the willingness to HPV vaccination among male university students in Tongzhou District, Beijing Municipality, so as to provide insights into the formulation of the HPV vaccination strategy among males. Methods: A total of 997 male university students in Tongzhou District were selected as the study subjects using a multi-stage stratified cluster random sampling method, and a self-designed questionnaire was used to investigate the awareness of HPV infections and HPV vaccine, and willingness to HPV vaccination. In addition, the factors affecting the willingness to HPV vaccination were identified. Results: A total of 935 subjects were enrolled, with a mean age of (19.08±1.38) years, and there were 570 subjects with a Beijing household registration (60.96%). Among the 313 male university students that had heard of HPV, the awareness of HPV and HPV-related diseases was 59.42%, and among the 300 male university students that had heard of HPV vaccines, the awareness of HPV vaccines was 75.33%. The willingness to HPV vaccination was 38.50%, and the willingness was high among male university students with a non-Beijing household registration ( χ2=3.971, P=0.046 ), high household annual income ( χ2trend=6.219, P=0.013 ), short distance to vaccination clinics ( χ2=19.238, P<0.001 ), having heard of HPV ( χ2=11.188, P=0.001 ), having heard of HPV vaccine ( χ2=14.548, P<0.001 ), awareness of HPV and related diseases ( χ2=16.855, P<0.001 ) and awareness of HPV vaccine ( χ2=19.299, P<0.001 ). Conclusions The awareness of HPV and HPV vaccines and the willingness to HPV vaccination are low among male university students in Tongzhou District. Improving the correct recognition of HPV and HPV vaccines and the access to vaccination services are helpful to improve the willingness to HPV vaccination among male university students.

Objective To determine the level of ieptin (LEP) and soluable leptin receptor (sLEP-R) in the peripheral blood of rheumatoid arthritis (RA). The change of LEP/sLEP-R in patients with RA and the relationship between LEP/sLEP-R with osteoporosis is also investigated. Methods Sixty-four patients with RA and 60 normal controls were involved. Levels of LEP and sLEP-R were measured by ELISA. Bone mineral density (BMD) of non-dominant forearm, lumbar vertebrae(L_(1～4)) and hip were measured by dual energy X-ray absorptiometry. Results ① Compared with normal controls, the level of LEP in RA increased significantly,but the level of sLEP-R in RA decreased significantly (P<0.01). ② BMD of all detected regions in RA were significantly reduced than those in the normal controls (P<0.01). There was a higher incidence of osteoporosis in patients with RA (35.9%) than in normal controls (15.0%)(P<0.01). ③ There was a positive lineary correlation between age and the level of LEP in the peripheral blood of RA (P<0.01). There was negative lineary correlations between BMD and level of LEP in the peripheral blood of RA (P<0.05). There was a negative lineary correlation between age and level of sLEP-R in the peripheral blood of RA (P<0.01). There was positive lineary correlation between BMD and level of sLEP-R in the peripheral blood of RA (P<0.05). There was no correlations between clinical or laboratory parameters and level of LEP/sLEP-R in the peripheral blood of RA. ④ Analysis of Logistic Regression showed that the level of sLEP-R in the peripheral blood of RA was an independent protective factor for the occurrence of osteoporosis in RA (OR=3.089, P=0.017, 95%CI: 0.017-7.108). Conclusion The level of LEP in RA increases significantly, while the level of sLEP-R decreases significantly. There is a closely correlation between bone metabolism status and the level of LEP or sLEP-R in RA. The level of sLEP-R in the peripheral blood of RA is an independent protective factor for the occurrence of osteoporosis in RA.

Objective To compare the QTc and QTcd between type 2 diabetic and non-diabetic patients with post-myocardial infarction (post-MI) ,and to compare the QTcd in type 2 diabetic patients with post-MI treated with insulin,sulfonylurea,mefformin,or diet alone. Methods We measured the QTc and QTcd through simultaneous 12-lead Electrocardiogram in 138 post-MI patients,including 70 type 2 diabetic (of which,23 were assigned to re-ceive insulin,20 glipizide,16 mefformin,11 diet control) and 68 non-diabetic patients. Result Compared with post-MI patients without diabetes,those with type 2 diabetes had significantly higher QTc [(377.2±24.3) ms vs (342.9±27.5)ms,t=7.79,P<0.01] and QTcd [(48.8±19.7)ms vs (40.3±26.6)ms,t=2.14,P<0.05]. There were no significant difference between the mefformin group and the diet control group (P>0.05). The QTc and QTcd in the insulin group were significantly higher than those in the other three group s(P<0.05),and the QTc and QTcd in the glipizide group were higher than those in the mefformin group or diet control group(P<0.05,and P<0.01,respectively). Conclusion Type 2 diabetes is associated with an additional increase in the QTcd in post-MI patients,suggesting higher mortality risk in post-MI patients with type 2 diabetes. Insulin and glipizide may in-crease the QTc and QTcd in post-MI patients with diabetes. These effects were more significant in the insulin therapy group.
