Objective To establish a method of primary culture of human preadipocyte in a serum-free medium. Methods Collangenase digestion was used to dispart preadipocyte.The cells were identified by microscopy stained by oil red O and determination of the activity of Glycerol-3-phosphate dehydronase(G-3-PDH). Results The primary cultured human preadipocyte proliferated in the aserum-free medium successfully.In the differential serum-free medium the cells turned to be round on the 4 th day.The adipose drops began to cumulate in the cells,and to the most quantity until the 21 st day.Conclusion The human preadipocyte can be primarily cultured and induced to differentiate in serum-free medium,which is the base for researching the effects of hormones and factors to the proliferation and differentiation of preadipocyte.

Objective:To study the effect of interleukin-11(IL-11),ciliary neurotropic factor (CNTF) and transforming growth factor-β (TGF-β) on the hGH gene promoter activity in rat pituitary MtT/S cells and the interaction with pituitary-specific transcription factor Pit-1.Methods:Stable transformed MtT/S cell line which contains hGH gene promoter -484-30 bp and luciferase reporter gene firstly established,then the concentration of GH in the medium and lysate of MtT/S cells and luciferase activities in MtT/S cells were measured after treatment these cells with the above cytokines,the effects of cytokines on secretion and synthesis of GH,and the promoter activity of the hGH gene were observed.Results:The results showed that IL-11(20 nmol/L),CNTF(10 nmol/L) and TGF-β(5 nmol/L) regulated secretion and synthesis of GH,and the luciferase expression in stable transformed MtT/S cells.IL-11 and CNTF had the stimulatory effect,whereas TGF-β had the inhibitory effect.Neither overexpression of Pit-1 nor inhibiting Pit-1 expression affected the regulatory role of these cytokines.Conclusion:IL-11,CNTF and TGF-β regulate the GH production in pituitary MtT/S cell line by regulating the hGH gene promoter activity.Pit-1 may not be involved in these actions.

Dongting Lake area is one of the major marshland schistosomiasis endemic areas in China. In recent years spatial epidemiology is widely used in the research of schistosomiasis which is a new opportunity to break through the current wander-ing situation of schistosomiasis control. In this article both the generalized and Dongting-Lake-specific epidemic indicators of schistosomiasis are reviewed to provide the basis to construct the schistosomiasis Geographic Information System GIS database of Hunan Province.

Objective To discuss the success rate of external cephalic version (ECV) for breech presentation in singleton pregnancies and the factors influencing ECV,and complications induced by ECV.Methods A prospective study was conducted which included 204 pregnant women who underwent regular prenatal examinations and delivered in Nanjing Drum Tower Hospital between March 1,2011 and February 29,2012.The 204 cases were single pregnancy with breech presentation identified by ultrasound during 32-37+6 weeks of gestation,and without other indications for cesarean section (CS).According to willingness of the participants,204 cases were divided into two groups.The 101 pregnant women who refused EVC (control group) were asked to practice knee-chest position twice a day; and 103 pregnant women volunteered to undergo EVC (ECV group) during 32-37+6 weeks of gestation.The proportion of cephalic presentation at delivery,CS rate and the incidence of PROM,premature delivery and cord around the neck were compared between the two groups.Factors influencing the success rate of ECV were analyzed.Chi-square or adjusted Chi-square test were used for statistical analysis.Results The proportion of cephalic presentation at delivery in the ECV group was higher than that in the control group [68.9％ (71/103) vs 29.7％ (30/101),x2=31.39]; the CS rate in the ECV group was lower than that in the control group [49.5％ (51/103) vs 78.2％ (79/101),x2=18.18],as was the rate of CS due to breech presentation [62.7％ (32/51) vs 89.9％ (71/79),x2=13.86],all P＜0.05.The success rates in frank breech presentation,complete breech presentation and incomplete breech presentation were 77.1％ (37/48),72.7％ (24/33) and 45.5％ (10/22),respectively (x2=7.37,P＜0.05),and the success rate in frank breech presentation was higher than that in incomplete breech presentation (x2=6.84,P＜0.017).No significant differences were observed in the success rates between primiparas and multiparas [67.7％ (63/93) vs 8/10,x2=0.19],placenta attached at front wall of uterus and other attachment sites [61.0％ (25/41) vs 74.2％ (46/62),x2=2.01],and EVC performed at 32-35+6weeks of gestation and 36-37+6 weeks [70.5％ (62/88) vs 9/15,x2=0.65],allP＞0.05.No significant differences were observed for the incidence of PROM [7.8％ (8/103) vs 6.9％ (7/101)],premature delivery [2.9％ (3/103) vs 2.0％ (2/101)] and cord around the neck [17.5％ (18/103) vs 21.8％ (22/101)] between the ECV and control group (x2=0.05,0.19 and 0.60,all P＞0.05).Conclusions ECV for breech presentation in singleton pregnancies can effectively correct the fetal position and reduce the CS rate.ECV performed after 32 weeks of gestation does not increase the risk of PROM and premature delivery.

Objective To explore the effects of skill-training on social function in patients with schizophrenia recession. Methods 60 patientswith schizophrenia recession were divided into 2 equal groups (n=30) for 1-year treatment. The control group was treated only withdrugs, and the treatment group was treated with skill-training in addition. The patients were assessed with the Scale of Social Skill of ChronicSchizophrenic Inpatients (SSSI) and the Positive and Negative Symptom Scale (PANSS) before, 6 months and 12 months after treatment.Results The total scores of PANSS decreased significantly in the treatment group compared with the control group (P<0.01). The scores ofSSSI decreased significantly in the treatment group after treatment. However, there was no significant differences in the control group (P>0.05) 6 months after treatment, but was 12 months after treatment (P<0.05). Conclusion Based on the medicine treatment, skill-training mayimprove the flinched mental symptom to remain the social function.

Objective To investigate the changes of serum N-terminal-pro-B-type natriuretic peptide (NT-proBNP) concentration in patients with Graves' disease (GD) and its clinical significance. Methods Two hundred and sixty-nine patients with GD were enrolled in this study. Serum concentrations of thyroid hormones,TRAb, and NT-proBNP were measured. Results Serum NT-proBNP levels were positively associated with FT3(r=0.260, P<0.01), FT4(r=0.297,P<0.01) and heart rate (r=0.251, P<0.05) independent of age,sex and body mass index (BMI). The difference of serum NT-proBNP concentrations between newly-onset and treated patients existed (P<0.01) after the adjustment for thyroid hormone levels, age, sex and BMI. Serum FT4level exerted a significant impact on NT-proBNP level (P <0.01). Serum NT-proBNP increased even in patients with controlled thyroid function. Conclusion Serum NT-proBNP level in patients with GD increases with elevation of FT4 independent of sex, age and BMI. The measurement of serum NT-proBNP concentration appears to be helpful to monitor the alteration of vascular stiffness and fluid volume in GD patients, and may provide useful evidence for early intervention of cardiovascular disease induced by hyperthyroidism.

Objective To compare the clinical efficacy and safety of domestic orlistat and imported orlistat in Chinese overweight and obese patients. Methods In a randomized, double-blinded and positive-controlled study, 228 adults (BMI 24-< 40 kg/m~2) evaluated at seven research centers were randomized to receive domestic orlistat or imported orlistat 120 mg 3 times a day with an energy-controlled diet for 24 weeks. Results After 24 weeks, domestic orlistat treated patients got significant weight-loss (5.0±3.7) kg, which was comparable with that of imported orlistat treated patients (4.5±3.5) kg (P=0.3922).Compared with the findings before treatment, there was significant decrease of systolic blood pressure (4.4±11.5)mm Hg (1 mm Hg=0.133 kPa) and serum levels of TC (0.54±0.79) mmol/L and LDL-C (0.32±0.64) mmol/L in the domestic orlistat treated group(compared with levels of baseline, P< 0. 0001). There was no significant difference between the two groups in the changes of blood pressure and lipid levels. Both groups had similar adverse event profiles, most of which were mild and transient gastrointestinal events. There were no serious adverse events in beth groups. Conclusions Domestic orlistat combined with a light low-energy diet promoted significant weight loss, which was comparable with that of imported orlistat after 24 weeks of treatment. There was also improvement in blood pressure and serum levels of TC and LDL-C. Domestic orlistat was as effective and safe as imported orlistat in the treatment of obesity.

Objective To evaluate the effects of a traditional Chinese medicine Rubia cordifolia L.aqueous extract (RCAE) on body weight, fat mass and parameters of glucose and lipid metabolism in high fat diet (HFD)-induced obese rats and its mechanism.Methods pGL3-Enhancer-PPARγ2 (625 bp)-Luc plasmid, a luciferase reportergene expression plasmid containing PPARγ2 promoter was constructed and stably transfected 3T3-L1 preadipocytes were established.PPARγ2 promoter`s activities in these cells were detected after administration with different concentration (0.1 mg/L~1 000 mg/L) of RCAE or with 100 mg/L RCAE for different action time.PPARγ2 mRNA expression in human adipocytes were detected after administration with 100 mg/L RCAE.Meanwhile, HFD-induced obese rats were administrated with low or high dose RCAE to investigate the effects of RCAE on serum glucose, lipid and insulin levels, body weight, visceral fat mass and so on.Results 10 mg/L RCAE could increase luciferase expression in 3T3-L1 cells to 1.43 folds of that in control group (P<0.01) and it reached 3.24 folds of that in control group when the concentration of RCAE was 1000 mg/L (P<0.01).With the administration with 100 mg/L RCAE, the luciferase activity of 3T3-L1 cells peaked at 28 h where it was 2.72 folds of that in control group (P<0.01), and the expression of PPARγ2 mRNA in human adipocytes increased to 2.27 folds of that in control group (P<0.01).Compared with HFD group, low dose RCAE significantly reduced the fasting insulin level, HOMA-IR and visceral fat mass (P<0.05).Conclusions Low dose RCAE significantly reduces the visceral fat mass and ameliorates insulin resistance in HFD-induced obese rats.The potential mechanism may be explained by the stimulation of PPARγ2 promoter activities and the increased expression of PPARγ2 gene.

Objective To assess the value of transesophageal echocardiography (TEE) in left atrial appendage (LAA) closer with Amplatzer Cardiac Plug (ACP).Methods Consecutive 32 atrial fibrillation patients (CHADS2≥1) with high risk bleeding underwent LAA occlusion with ACP LAA occlusion device under the guidance of TEE.Measurements of LAA anchoring area diameter (AAD) and LAA anatomical orifice diameter (AOD) including maximum,minimum values,and LAA depth on 2 dimentional TEE (2D TEE) were conducted before closer device implantation.The outcomes of LAA occlusion were analyzed.Results Among 32 patients,27 cases achieved successful LAA occlusion,including 2 cases with peripheral leakage ≤5 mm,and 5 cases failed occlusion.Among 5 failed closed patients,3 cases with LAA AAD≥ 30 mm,1 case with LAA of short depth,and 1 case with anatomical variation of LAA of low position that access sheath could not be positioned in the LAA.LAA AAD maximum,minimum and LAA depth were (25.9±4.9)mm,(20.0±3.8)mm,(31.0±5.6)mm,respectively,and LAA AOD maximum,minimum diameters were (26.2±6.2)mm,(19.4±4.3)mm,respectively.Among 10 cases with LAA AAD≥30 mm,7 cases achieved successful LAA occlusion,but 3 cases failed.The implanted device diameter was (26.4±3.8)mm,and device compression rate was (7.6±5.5)%.The coefficient of correlation between device diameter and large LAA AAD and AOD is 0.770 and 0.717,respectively.There was no complication but 1 case with pericardial effusion.Conclusions Two dimentional TEE measurements of LAA have clinical guiding significance in the selection of proper size of ACP LAA occluder.The AAD of 2D TEE has the good correlation with ACP occluder′s size,the AADs are important factors which affect the success of LAA occlusion.
