Objective: To investigate the changes of gallbadder motive function in diabetics. Method: The size of gnllbadder,recovering rate,echo and half-empty time after fat food were compared and statistically analyzed between 22 healthy individuals and 20 diabetics with ultrssonograph. Results:The gallbadder recovering rate was similar between the healthy individuals and diabetics (P>0.05), but the rate of cholecystitis (30%) and choletethiasis (35%) of diabetics were higher than those in healthy individuals, the gallbadder half-empty time after fat food was obviously slower in diabetics (46.1+12.9 min)than those healthy individuals (27+4.4 mmin). Conclusions: The diabetics had obvious gallbadder motive funciion obstruction and higher rates of chronic cholecystitis and choletethiasis with ultrasonograph observations.

Objective To investigate the distribution and effect of endothelial nitric oxide synthase (eNOS) on the zero-stress state of carotid arteries in rats at different ages.Methods Morphometry and microstructure of carotid artery in 3-month-old,6-month-old and 12-month-old Sprague-Dawley rats were studied quantitatively by histological method and computer image analysis.Immunohistochemistry and the NADPH-diaphorase reaction were used to localize the endothelial nitric oxide synthas (eNOS) in different age rats.The changes of opening angle in the zero-stress state was also observed.Results With increasing age,there was a significant reconstruction changes in morphometric parameters and microstructure parameters of the carotid arteries in rats.While the expression of eNOS protein of endothelium and vascular smooth muscle cells were decreased.Compared with 3-month-old rats,the zero-stress state.of opening angle in 6-month-old and 12-month-old group were increased.However,pre-incubation of vessel rings with L-arginine (30 mmol/L),a substrate of eNOS,attenuated the changes of the zero-stress state.Conclusions The results suggest that the carotid arterial wall in different age rats shows unequal growth and different zero-stress state eNOS may be involved in the age-related changes of zero-stress state of the carotid artery in aged rats.The results may provid an experimental base for vascular transplantation and vascular reconstruction.

To obtain fusion protein of Mycobacterium bovis with high purity, the recombinant prokaryotic expression vector for Mb2277 gene was constructed and the immunogenicity of its products was initially investigated in the present study.A pair of primer was designed according the gene sequence Mb2277 from the genomic DNA of M.Bovis in GenBank. and was amplified by PCR using DNA of M.Bovis 93006 strain as template. The PCR product and pET-28a(+) was then digested by BamHⅠ and EcoR Ⅰdouble enzyme. To constructed a prokaryotic expression plasmid, the purified Mb2277 was cloned to pET28a(+). Then the recombinant plasmid was transformed into competent cell of E.coli BL21(DE3).The bacteria were induced by IPTG and its lysates were analyzed by SDS-PAGE and Western-blotting. In this way, the prokaryotic expression plasmid for M. bovis Mb 2277 protin was obtained, and a expression band with molecular of 25 ku could be found in SDS-PAGE analysis. As demonstrated by Western blotting this expression product showed excellent reactivity with rabbit immune sera against M. bovis.

Objective To investigate the differences in clinical, laboratory and therapeutic aspects of primary Sjogren's syndrome (pSS) between young/middle-age group and old group.Methods The 84 pSS patients were divided into the young and middle-age group (n=54) and the old group (n = 30). The differences in clinical features, laboratory indices and drug therapy were retrospectively analyzed. The chi-square test was used for statistical analysis. Results The positive incidences of xerostomia, dry eye symptom and rampant teeth were 80.0%, 76.7% and 43.3%respectively in the old group. And they were all significantly higher than in young and middle-aged group (57.4%, 51.9% and 20.4%, all P＜0. 05). The positive rates of rheumatoid factor (RF)elevation, antiRo/SSA and antiLa/SSB antibodies were 13. 0%, 36.7% and 16.7% in the old group,and significantly lower than in young and middle-age group (44.4%, 59.3% and 42.6%, all P＜0.05). The incidences of leukopenia and thyroid gland involvement were much lower in the aged group (13.3% and 10.0%) than in the young and middle-age group (48. 1% and 37.0%, P＜0. 05). The percentage of patients receiving hydroxychloroquine as the main medicine was much lower in the aged group than in the young and middle-age group (16.7% vs. 40. 7%, P＜0. 05), while percentage of treatment with exclusive glucosides of Paeony Capsules was much higher (33.3% vs. 14.8%, P＜0.05). There were no statistical differences between two groups in ophthalmological examination,immunoglobulin level and sialography. Conclusions Those pSS patients with late onset exhibit more abnormalities in clinical parameters, but fewer in immunological parameters, which may be helpful in estimating prognosis and pathogenetic factors in pSS.

ObjectiveTo investigate the iodine nutritional status of pregnant women,newborn heel blood thyroid stimulating hormone(TSH) level and their relationship with urinary iodine(UI) level during pregnancy in Zhoupu and Kangqiao districts of Pudong New Area of Shanghai.Methods A total of 993 urinary samples(the first,second and third trimesters of pregnancy were 200 people,respectively),breast feeding(193 people) and non-pregnant women (200 people) in Zhoupu and Kangqiao districts of Pudong New area were collected from Apr 2009 to Dec 2010.Two hundred copies of neonatal heel blood samples were collected.Median of UI was measured by arsenic-cerium catalysis.TSH in neonatal heel blood was analyzed 72 h after birth by time resolved fluoroisnmunoassay(TRFIA).ResultsMedian UI of all pregnant women was 161.35 μg/L,and that in third trimesters of pregnancy( 126.35 μg/L) was lower than that of the first,the second,the breast feeding and non-pregnant women (178.80,180.50,167.90,163.40 μg/L,all P＜ 0.05).The percentage of UI level less than 150 μg/L in the third trimester[57.5％(115/200) ] was higher than that of the first[39.0％(78/200) ],the second[39.5％(79/200) ],the breast feeding [ 16.6％ (32/193) ] and non-pregnant women [ 23.0％ (46/200) ],respectively (all P ＜ 0.05).The percentage of UI level higher than 300 μg/L in the first [9.0％(18/200)],the second[8.0％(16/200) ] and the third trimester [ 5.0％ ( 10/200 ) ] of pregnancy was lower than that of the breast feeding [ 20.2％ (39/193) ] and nonpregnant [20.5％(41/200) ] women,respectively(all P ＜ 0.05).The level of neonatal heel blood TSH was(2.92 ± 1.83)mU/L,the range was 0.01 - 9.76 mU/L,11.0％(22/200) of the neonates heel blood TSH level(5 mU/L)exceeded the ratio of World Health Organization (WHO) standard ( ＜ 3％ ) suitable for iodine nutrition.Conclusions The overall level of iodine nutrition among pregnant women in Zhoupu and Kangqiao districts of Pudong New Area of Shanghai is in the appropriate range,but the pregnant women in the third trimester is in mild iodine deficiencies,and the neonates in these districts may be prone to iodine deficiency.Monitoring of iodine nutrition of pregnant women should be strengthened and iodine supplementation should be done scientifically.

Objective To identify predictors of prescription initiation and persistence of warfarin in non-valvular atrial fibrillation ( NVAF ) patients with high risk of stroke ( CHA2 DS2-VASc≥2 ) . Methods NVAF patients consulted in our hospital from Aug , 2011 to Apr, 2015 were enrolled.Patients who underwent radiofrequency catheter ablation were excluded . Patients were divided into two groups (warfarin group and non-warfarin group).Logistic regression was used to estimate the predictors of initiation warfarin prescription.Kaplan-Meier survival and Cox proportional hazards model was performed to determine rate of warfarin persistence and its associated factors .Results A total of 622 AF patients were enrolled and 490 patients with CHA2DS2-VASc≥2.Ten patients lost follow up and 480 patients were followed up with a mean follow-up period of ( 40.0 ±11.55 ) months.Of which 245 NVAF patients ( 51%) had a warfarin prescription.Patients with ischemic stroke ( OR 2.447 , 95%CI 1.435-4.171 , P=0.001 ) , heart failure ( OR 2.009 , 95%CI 1.084-3.724 , P=0.027 ) and persistent AF ( OR 2.231 , 95%CI 1.448-3.437 , P=0.0001 ) had a higher likelihood of warfarin prescription .Anemia ( OR 0.479 , 95%CI 0.238-0.964 , P=0.039), concommitant Traditional Chinese Medicine (TCM) use (OR 0.638, 95%CI 0.456-0.891, P=0.008 ) and longer distance to hospital ( OR 0.759 , 95%CI 0.610-0.945 , P=0.014 ) decreased the likelihood of warfarin prescription . One hundred and seventy-six ( 71.8%) warfarin users continued persistent therapy and the overall proportion of warfarin persistence was 78.3% for one year , 71.0% for 3 years.Seventy-six existing warfarin users continued the warfarin therapy (80%, 76/95),one hundred new users showed persistence to therapy ( 66.7%, 100/150 ) .Warfarin use before enrollment significantly increased warfarin persistence than new prescription ( P =0.008 ) .Variables associated with higher discontinuation were new prescription ( HR 1.786 , 95% CI 1.029-3.100 , P=0.039 ) , TCM use ( HR 1.687 , 95%CI 1.201-2.37 , P=0.003 ) and longer distance to hospital ( HR 1.446 , 95% CI 1.121-1.865, P=0.005).Conclusions In anticoagulation clinic, concommitant TCM use, distance to hospital and other factors were associated with warfarin initiation prescription and persistence .Identifying factors associated with warfarin treatment could help in developing adherence of patients .

Objective To observe the protection of human lens epithelial cells(HLEC) by different polar alkaloids extracted from Herba Dendrobii(HD).Methods We extacted the Herba Dendrobii powder with ethanol,and then treated the extract with falling-film concentration,acidification,salting out,chloroform extraction,and washing with water.Different polar alkaloids were extracted from HD after the above treatment.The protective effect of HD alkaloids was observed on HLEC,which were cultured with DMEM medium containing 10% fetal calf serum.Ten groups were set up for the experiment: normal control group,model group,high-and low-dose water-soluble alkaloids groups,high-and low-dose fat-soluble alkaloids groups,high-and low-dose low-polar alkaloids group,and high-and low-dose weak-polar alkaloids groups.The high-dose dosage of the alkaloids was 25.0 ?g/L and low-dose dosage was 12.5 ?g/L.Methyl thiazolyl tetrazolium(MTT) assay was used to evaluate the proliferation of HLEC under the different conditions of interventions.Results The single-factor experiments showed that the highest extracting rate of HD alkaloids was obtained under the conditions of extracting the powder with 80% ethanol for 3 times and for 3 hours.The results of protective experiment showed that the proliferation of HLEC in the model group was inhibited by hydrogen peroxide(H2O2),and the inhibitive rate was lower in low-dose fat-soluble alkaloids group than that in the model group(P
