Objective To investigate epidemic infections of the three infective diseases such as Hepatitis C, Syphilis, AIDS in the pregnant women in Xinyi.Methods The anti-hepatitis C virus antibody (anti-HCV), anti-Treponema pallidum antibody (anti-TP) and anti-human immunodeficiency virus (anti-HIV) were tested on the samples from 9,092 pregnant women hospitalized for birth delivery in the obstetric departments of hospitals and obstetric clinics.Results The detection rates of the three infective diseases were1.54 ‰ (14/9092) for anti -HCV, 5.83 ‰(53/9092) for anti-TP, and 0.55 ‰(5/9092) for anti-HIV.There was no statistically signifi-cant difference in the infection rate by the three pathogens among the age group.Conclusion The infection rates of HCV, TP and HIV are high among the pregnant women in Xinyi.The prenatal screening should be further strength-ened to promote the prenatal and postnatal care.

Background Thyroid-associated ophthalmopathy (TAO) is a kind of clinically common and incurable ocular disease,and its incidence is at top place.The etiology and pathologic mechanism of TAO are still unknown because of shortness of replicative animal models and difficulty to acquire the ocular tissues in the early stage of the disease.To better understand the pathogenesis of TAO and investigate effective treatable measures, an appropriate animal model should be developed.Objective This study was to immunize female BALB/c mice with the recombinant plasmid of human thyroid-stimulating hormone receptor (TSHR) extracellular domain in cationic liposomes for the establishement of TAO models.Methods Thirty-two 6-to 8-week-old female BALB/c mice were randomly assigned to four groups according to computer random allocation.pcDNA3.1 +/hTSHR289 of 100 μg in an adjuvant cationic liposomes was injected via anterior tibialis muscle and peritoneal cavity separately in the recombinant plasmid injection group in 0, 3,6 weeks, and pcDNA3.1 or cationic liposomes was injected in the liposomes injection group or the blank plasmid group in the same way, respectively, and normal saline solution was injected in the blank control group.Body weight of the mice was measued before and 1 month,2,3 and 4 months after initial injection.The manifestations were observed after modeling.The mice were sacrificed 17 weeks after initial injection,and the histopathology examination was carried out on the thyroid gland and orbital tissue.The heart blood was collected from the mice,and serum contents of total thyroxin 4 (TT4) and thyroid-stimulating hormone (TSH)were assayed by ELISA.Results Protrusion, eyelid swell and keratitis occurred in 12 eyes of 6 mice in the recombinant plasmid injection group after immunization.A significant difference in the body weight of the mice was found among the blank control group, blank plasmid group, liposomes injection group and recombinant plasmid injection group (Fgroup =3.425, P =0.028), and the body weight was considerably reduced in the recombinant plasmid injection group in comparison with the blank control group, blank plasmid group,liposomes injection group (Ftime =0.838 ,P=0.023).The serum levels of TT4 were (7.75±1.00), (7.96±0.76), (6.76±1.10) and (4.43±2.88) μg/dlin the blank control group, liposomes injection group, blank plasmid group, and recombinant plasmid injection group, and those of TSH were (6.36±2.58),(4.83±3.96),(6.63±1.71) and (1.60 ±1.76) ng/ml, showing significant differences among the groups (F =7.150, P＜0.001;F =5.521, P＜0.01) , and the serum levels of TT4 and TSH were remarkably lower in the recombinant plasmid injection group than those of the blank control group,liposomes injection group and blank plasmid group (all at P ＜ 0.05).Histopathology revealed the lymphocyte infiltration of thyroid gland in 6 mice and proliferation of orbital adipose tissue, infiltration of lymphocytes and mastocytes,deposition of hyaluronic acid as well as swell, breakage and inflammatory cell infiltration of extraocular muscle in 15 eyes of the recombinant plasmid injection group.Conclusions A murine model of TAO can be successfully induced by immunization with recombination plasmid pcDNA3.1 +/hTSHR289 and cationic liposomes.The histopathology characteristics and ocular findings of the animal models are similar to human TAO.

Objective To establish the animal model of gestational diabetes mellitus (GDM to observe the long-term effect of maternal hyperglycemia and postnatal overfeeding on the metabolism of offsprings. Methods Streptozotocin (STZ, 50 mg/kg) was administered to Wistar rats intraperitoneally on the 5th day of gestation to induce animal GDM model. Offsprings were allocated into 3 groups: Group CP (n=8) were exposed to normal maternal hyperglycemic environment, group DP-1 (n=8) exposed to intrauterine hyperglycemia and every 8 pups breast-fed by one GMD mother and group DP-2 exposed to intrauterine hyperglycemia and every 4 pups breast-fed by one GDM mother (n=8). Weight gain between 3-10 weeks were recorded, OGTT at 10 weeks and hyperinsulinemia-euglycemia clamp technique was performed, and plasma insulin level was measured by ELISA at 11 weeks. Results Offsprings in DP-1 and DP-2 group had greater weight gain than group CP at 3-10 weeks after birth [(6.68±1.70)% and (6.03±1.85)% vs (4. 74±0.93)%, P< 0. 05], but no difference was found among the three groups in OGTT results (P> 0. 05). The baseline plasma insulin level was lower in the DP-1 group than in the DP-2 and CP group [(0. 76± 0. 37)μg/L vs (1.13±0. 25)μg/L and (1.06±0. 14)μg/L](P<0. 05). GIR60-120 was higher in DP-1 Offsprings of Wistar rats, exposed to intrauterine hyperglycemia, experience excessive weight gain at 3-10 weeks after birth. Overfeeding in early life expedites the decrease of insulin sensitivity in these offspings.

Objective To study the effect of intrauterine hyperglycemia on leptin level and offspring development in rats.Methods Female and male adult Wistar rats were mated,streptozotocin (STZ,50 mg/kg) was administered intraperitoneally on 5th day of gestation to induce diabetic model,diabetic pups (DP) were exposed to intrauterine hyperglycemia;control pups(CP) were exposed to controls,which was injected with citrate buffer,8 pups were choosed from each group.Weight gain between 3-10 weeks were recorded.Plasma leptin was detected by enzyme-linked immunosorbent assay (ELISA) when the rats were 11 weeks old,and the expression of leptin receptor in hypothalamus was measured at protein level by histomorphology and mRNA level measured by realtime PCR[expressed with integral absorbance(IA)]in 11weeks in order to discuss the relation of leptin and offspring development.Results The fasting blood glucose level was significantly higher in diabetic mother compared with the controls[(28.3±5.1) mmol/Lvs.(6.3±1.4) mmol/L,P＜0.05].However,there was no difference between the fasting blood glucose level in DP group and CP group[(5.1±0.8) mmol/L vs.(5.3± 0.6) mmol/L,P ＞ 0.05].The growth rate between 3-10 weeks was significantly higher in DP group 649.7% than CP group 479.2%,P ＜0.05.The base insulin level was lower in DP group[(0.76±0.37) μg/L vs.(1.06±0.14)μg/L,P ＜ 0.05];while there was no difference in plasma leptin and the expression of ieptin receptor in hypothalamns[(113±37) μg/L vs.(128±40) μg/L,P ＞0.05].The growth rate was not associated with plasma leptin in DP group (r=-0.501,P=0.311) but associated in CP group (r=-0.553,P=0.001).The protein level of DP group (4125±414) did not significantly differ from that of CP group (4244±511).The median of mRNA of leptin receptor in hypothalamus in DP group did not altered significantly compared with that of CP group(1.25 vs 1.80,P＞0.05).Conclusions Intrauterine hyperglycemia accelerated growth rate of offsprings between 3 and 10 weeks,however,plasma leptin was not discreased,which indicated leptin resistance.Intrauterine hyperglycemia did not influence the expression of leptin receptor in hypopthalamus in offsprings,this suggested the leptin resistance may be not caused by the quantity of leptin receptors.

ObjectiveTo investigate the effects of sex hormones( 17 β-estradiol and testosterone)on human omental preadipocytes proliferation and differentiation and on leptin and adiponectin secretions in adipocytes.Methods Omental preadipocytes were cultured and then differentiated into mature adipocytes in vitro.The proliferation and differentiation processes of preadipocyte were observed.The preadipocytes were incubated in the presence of sex hormones and were detected the contents and gene expressions of leptin and adiponectin.ResultsHuman preadipocytes were primarily cultured successfully.Estradiol stimulated preadipocytes proliferation (0.823±0.059 vs 0.276 ±0.032,P＜0.05 ),and inhibited lipid accumulation in cell differentiation ( P＜0.05 ).Testosterone had no significant effect on proliferation of preedipocytes,but inhibited adipogenic differentiation ( P＜0.05).Leptin could be detected during proliferation and differentiation of preadipocytes.Estradiol increased the leptin secretion,whereas testosterone reduced it ( all P ＜ 0.05 ).The adiponectin only could be detected during differentiation.Sex hormones reduced the adiponectin secretion.17β-estradiol stimulated leptin mRNA expression and suppressed adiponectin mRNA expression in adipocytes.Testosterone suppressed the mRNA expressions of leptin and adiponectin (all P ＜ 0.05 ).ConclusionIn vitro,17β-estradiol increases the leptin secretion and mRNA expression whereas reduced the adiponectin secretion and mRNA expression.Testosterone reduced the adiponectin and leptin secretion and mRNA expression.

Objective To investigate into hand hygiene facilities and worker's practice of hand hygiene during 120 ambulance services in a capital city.Methods With the standard Observation Form publicized by the World Health Organization,field observation was carried out to monitor hand hygiene facilities and the practice of hand hygiene in workers during ambulance services provided by four service centers.Results A total of seven ambulances and 80 times of services were observed across a span of 21 days.The provision and position of hand hygiene facilities were found very limited in these ambulances.Of 656 times of presence of indictors for hand hygiene,the overall compliance rate was 3.04％ reflecting the practice of hand hygiene in ambulance workers.The compliance rate was found to be 0 (0/291),1.96％ (1/51),13.64％ (3/22),5.21％ (16/307) and 0(0/2) before touching patients,after body fluids exposure risk,before clean/aseptic procedures and after touching patients' surroundings respectively.Conclusions Poor practice of hand hygiene which was revealed in 120 ambulance services suggests the great need for education and training to improve patient safety and occupational health.

Objective To establish assay methods for the determination of dissolution,content and related substances of vita-min K1 self-nanoemulsifying drug delivery system(VK1-SNEDDS),and investigate the physico-chemical properties of the preparation. Methods The UV method was established to determine the dissolution of VK1-SNEDDS. The content and related substances were de-termined by HPLC. The appearance,self-emulsification time,micro-morphology,droplet size and zeta potential were also investigat-ed. Results The linearity range of established UV and HPLC methods was 0.85-20.4 and 2.16-216μg/ml,respectively,and all the recovery,precision,specificity and sensitivity met requirements. VK1-SNEDDS could disperse quickly after dilution. The transmission electron microscope(TEM)image of the optimized liquid SNEDDS showed that most of the emulsion droplets were of uniform size with no signs of coalescence. Droplet size of optimal formulation was revealed as 47.74 nm with polydispersibility index(PDI)of 0.248,and zeta potential was found to be-20.53 mV. Conclusion VK1-SNEDDS could form homogeneous and stable nanoemulsion when dilut-ed with aqueous phase and increase the dissolution of lipophilic drug. The methods are reliable,accurate and suitable for quality con-trol of VK1-SNEDDS.

Objective To optimize the formulation of metoprolol succinate ( MS) controlled release pellets by central composite design-response surface methodology .Methods MS sustained-release pellets were prepared using sugar pellet cores as starter beads , ethyl cellulose as coating materials and MS itself as a pore former .The formulation of MS sustained-release pellets was optimized by a central composite design with two factors at five levels .These two factors ( two independ-ent variables) were the pore former level and coating level , and the evaluated indexes ( namely dependent variables ) included the in vitro cumulative release percentages of MS at 1, 4, 8, 12 and 16 h, respectively.Results and Conclusion The results of mathematical equation fitting suggested that the second-order quadratic model was the optimal fitting equa-tion.According to the response surfaces , the optimum values at the pore former level and coating level weve ranged from 16%to 18%and 20% to 25%, respectively .The in vitro cumulative release percentage of MS from the pellets at 1 h reached 9.15%,which consequently eliminated the lag phase in the initial release period and exhibited a good sustained-release effect.Central composite design-response surface methodology can be applied to optimizing the coating formulation for MS sustained release pellets .
