Effects of rhGLP-1 (7-36) on Akt/GSK3 signaling pathway in hepatocytes / 中华内分泌外科杂志

Objective:To observe the effect of rhGLP-1 (7-36) on Akt/GSK3 signaling pathway in hepatocytes.Methods:Human HL7702 cell line was cultured to the logarithmic growth stage and divided into experimental group and blank control group. The cultures were incubated with 100nM medium containing rhglp-1 (7-36) and without rhglp-1 (7-36) for 90min. The levels of Akt, Glycogen synthase Kinase 3 (GSK3) and Glycogen synthase (GS) in the two groups were detected by Western Blot.Results:Compared with blank control group, the protein expression of p-Akt (Thr308) in experimental group (1.81±0.28) was significantly increased ( P=0.01), but the protein expression of Akt and p-Akt (Ser473) was not significantly changed. The protein expression levels of p-GSK3α (Ser21) (1.27±0.09) and p-GSK3β (Ser9) (1.24±0.09) in the experimental group were significantly increased ( P=0.003, 0.002), while the protein expression levels of GSK3α and GSK3β were not significantly changed. The protein expression level of p-GS (Ser641) (0.70±0.16) was decreased in the experimental group ( P=0.03), but the protein expression level of GS did not change significantly. Conclusion:Glp-1 can inhibit GSK3/GS signaling pathway, activate GS activity and promote glycogen synthesis.

Comparison of the effectiveness and pregnancy outcomes of labor induction with dinoprostone or single-balloon catheter in term nulliparous women with borderline oligohydramnios / 中华医学杂志(英文版)

BACKGROUNDS@#At present, there is no consensus on the induction methods in term pregnancy with borderline oligohydramnios. This study aimed to compare the effectiveness and pregnancy outcomes of labor induction with dinoprostone or single-balloon catheter (SBC) in term nulliparous women with borderline oligohydramnios.@*METHODS@#We conducted a retrospective cohort study from January 2016 to November 2018. During the study period, a total of 244 cases were enrolled. Of these, 103 cases were selected for induction using dinoprostone and 141 cases were selected for induction with SBC. The pregnancy outcomes between the two groups were compared. Primary outcomes were successful vaginal delivery rates. Secondary outcomes were maternal and neonatal adverse events. Multivariate logistic regression was used to assess the risk factors for vaginal delivery failure in the two groups.@*RESULTS@#The successful vaginal delivery rates were similar between the dinoprostone group and the SBC group (64.1% [66/103] vs. 59.6%, [84/141] P = 0.475), even after adjustment for potential confounding factors (adjusted odds ratio [aOR]: 1.07, 95% confidence interval [CI]: 0.57-2.00, P = 0.835). The incidence of intra-amniotic infection was lower in the dinoprostone group than in the SBC group (1.9% [2/103] vs. 7.8%, [11/141] P < 0.001), but the presence of non-reassuring fetal heart rate was higher in the dinoprostone group than in the SBC group (12.6% [13/103] vs. 0.7%, [1/141] P < 0.001). Multivariate logistic regression showed that nuchal cord was a risk factor for vaginal delivery failure after induction with dinoprostone (aOR: 6.71, 95% CI: 1.96-22.95). There were three factors related to vaginal delivery failure after induction with SBC, namely gestational age (aOR: 1.51, 95% CI: 1.07-2.14), body mass index (BMI) >30 kg/m2 (aOR: 2.98, 95% CI: 1.10-8.02), and fetal weight >3500 g (aOR: 2.49, 95% CI: 1.12-5.50).@*CONCLUSIONS@#Term nulliparous women with borderline oligohydramnios have similar successful vaginal delivery rates after induction with dinoprostone or SBC, with their advantages and disadvantages. In women with nuchal cord, the risk of vaginal delivery failure is increased if dinoprostone is used in the induction of labor. BMI >30 kg/m2, large gestational age, and estimated fetal weight >3500 g are risk factors for vaginal delivery failure after induction with SBC.

Single-cell RNA Sequencing Reveals Thoracolumbar Vertebra Heterogeneity and Rib-genesis in Pigs / 基因组蛋白质组与生物信息学报·英文版

Development of thoracolumbar vertebra (TLV) and rib primordium (RP) is a common evolutionary feature across vertebrates, although whole-organism analysis of the expression dynamics of TLV- and RP-related genes has been lacking. Here, we investigated the single-cell transcriptome landscape of thoracic vertebra (TV), lumbar vertebra (LV), and RP cells from a pig embryo at 27 days post-fertilization (dpf) and identified six cell types with distinct gene expression signatures. In-depth dissection of the gene expression dynamics and RNA velocity revealed a coupled process of osteogenesis and angiogenesis during TLV and RP development. Further analysis of cell type-specific and strand-specific expression uncovered the extremely high level of HOXA10 3'-UTR sequence specific to osteoblasts of LV cells, which may function as anti-HOXA10-antisense by counteracting the HOXA10-antisense effect to determine TLV transition. Thus, this work provides a valuable resource for understanding embryonic osteogenesis and angiogenesis underlying vertebrate TLV and RP development at the cell type-specific resolution, which serves as a comprehensive view on the transcriptional profile of animal embryo development.

OBJECTIVE：To establis h the fingerprint of Lonicera japonica polysaccharide，and to investigate in vitro inhibitory effect of it on respiratory syndrome virus （RSV）. METHODS ：Polysaccharide from L. japonica was prepared by water extraction and twice alcohol precipitation method. After hydrolysis with trifluoroacetic acid ，derivatization with hydroxylamine hydrochloride and pyridine ，the fingerprint was established by GC method. The determination was performed on HP- 5 capillary column ，and the detector was flame ionization detector ；the temperature of the sample inlet was 250 ℃；the temperature of the detector was 300 ℃ （programmed temperature ）；the carrier gas was nitrogen （flow rate of 50 mL/min）；split sampling was adopted （split ratio of 60∶1）；the sample size was 2.0 μL. Using rhamnose as reference substance，GC fingerprint of 12 batches of L. japonica （S1-S12） was drawn ，and the similarity evaluation was performed with Similarity Evaluation System of TCM Fingerprint （2012 edition）. Cluster analysis and principal component analysis were conducted by using SPSS 21.0 software. Using ribavirin as positive control ， half effective concentration （EC50）and treatment index （TI）as indexes ，MTT assay was used to investigate in vitro inhibitory effect of L. japonica polysaccharide on RSV. RESULTS ：There were 12 common peaks in GC fingerprint of 12 batches of L. japonica. The similarity was greater than or equal to 0.994. Seven common peaks were identified ，such as rhamnose ，arabinose， fucose，mannose，glucose，galactose，inositol hexaacetate. According to the cluster analysis ，12 batches of samples could be divided into two categories ，i.e. S 1，S7，S10 and S 11 clustered into one category ，and others clustered into one category. In principal component analysis ，the eigen values of 3 principal components were all greater than 1 （5.659，2.745，1.724 respectively），and their cumulative contribution rate was 84.400％. The comprehensive score of S 12 was the highest ，the second was S 5，and the lowest was S 11. EC 50 of total polysaccharide ，80％ alcohol precipitated polysaccharide ，50％ alcohol precipitated polysaccharide and 20％ alcohol precipitated polysaccharide of L. japonica （No. S 12） were 0.76，0.61，1.03，3.04 g/L， respectively；TI were 15.36，18.51，11.69，4.22，respectively. EC 50 of 80％ ethanol alcohol precipitated polysaccharide was the lowest，and its TI was close to that of positive control （20.08）. CONCLUSIONS ：Established fingerprint provides reference for the quality evaluation of L. japonica . L. japonica polysaccharide has a certain inhibitory activity on RSV in vitro ，and the 80％ alcohol precipitated polysaccharide has the strongest activity.

Association between fresh fruit consumption and glycemic control in patients with type 2 diabetes / 中华流行病学杂志

Objective@#To investigate the association between fresh fruit consumption and status of glycemic control, among patients with type 2 diabetes mellitus (T2DM).@*Methods@#Using the stratified cluster sampling method, a cross-sectional study was conducted among 19 473 diabetic patients who were under the Disease Management Program related to the National Basic Public Health Service in Changshu county, Huai’an and Qinghe districts of Huai’an city from December 2013 to January 2014, under the combination of fasting plasma glucose (FPG) and haemoglobin A1c (HbA1c) methods, the glycemic control status in T2DM patients was assessed. Multiple logistic regression method was used to explore the relationship between fresh fruit consumption and status of glycemic control among T2DM patients.@*Results@#62.4% of the T2DM patients reported their amount of fruits intake in the past year. Both the levels of FPG and HbA1c decreased in T2DM patients, when the frequency and amount of fresh fruit consumption were increasing. Compared with patients who did not take fresh fruits, the risk of poor glycemic control in patients with fresh fruit consumption of 1-4 times/week and ≥5 times/week decreased 20% (OR=0.80, 95%CI: 0.73-0.87) and 30% (OR=0.70, 95%CI: 0.62-0.80), respectively. Patients with fruit consumption of 50-99 g/day and ≥100 g/day had lower risk of poor glycemic control, with ORs (95%CI) as 0.71 (95%CI: 0.62-0.83) and 0.68 (95%CI: 0.59-0.78), respectively.@*Conclusions@#The association of fresh fruit intake and glycemic control was statistically significant in patients with type 2 diabetes. With the increase of frequencies and amounts of fresh fruit consumption, the levels of FPG and HbA1c showed a decreasing trend. Our findings suggested that fresh fruit intake seemed helpful for glycemic control.

Effect of endothelial cell-targeted soluble Notch ligand hD1R protein on the proliferation of acute myeloid leukemia cells / 中华血液学杂志

Objective@#To evaluate the effects of endothelial cell-targeted soluble Notch ligand hD1R protein on the proliferation of acute myeloid leukemia (AML) cells.@*Methods@#The expression levels of Notch1, Notch2, Notch3, Notch4, Hes1 in bone marrow CD34+ cells from 24 cases of untreated AML (AML group) and 9 healthy controls (control group) were determined by real time quantitative polymerase chain reaction (PCR) . Recombinant hD1R protein was first induced and purified. Bone marrow CD34+ cells were co-cultured on human umbilical vein endothelial cells (HUVEC) supplemented with a cocktail containing 5 types of human cytokines (5GF) and soluble hD1R. The cultured cells were tested under different culture conditions including PBS group (PBS replaces HUVEC) , hD1R group, 5GF group, GSI group (hD1R plus GSI) . Proliferation and apoptosis of cultured cells were also analyzed. Real time quantitative PCR was used to test the expression levels of Hes1 and Bcl-2 in cultured cells.@*Results@#The expression levels of Notch1 and Hes1 in primary AML patients were significantly lower, and Notch4 expression was higher compared to the control group (P<0.05) . Cell counting showed a remarkable decrease of AML cells number in the culture with hD1R compared with that in the PBS group[ (0.74±0.13) ×105 vs (2.16±0.21) ×105, P<0.01]. FACS analysis showed that the percentage of AML cells was (18.48±2.51) % in apoptosis, which was higher than that of control cells (3.19±0.58) % after co-culture with hD1R. AML cells in the hD1R group underwent significantly increased apoptosis compared with those in the PBS one (P<0.05) . Moreover, apoptosis of AML cells in the GSI group was lower than that in the hD1R one (P<0.05) . Apoptosis in the PBS group also decreased compared with that in the 5GF one (P<0.05) . Finally, hD1R up-regulated Hes1 expression and inhibited Bcl-2 one in the AML cells.@*Conclusion@#hD1R effectively activated Notch signaling and down-regulated Bcl-2 mRNA in AML cells, which lead to cell apoptosis.

On the achievement of comprehensive control targets among type 2 diabetic patients managed by communities in Jiangsu province / 中华内分泌代谢杂志

Objective To explore the control levels of blood glucose,blood lipid,blood pressure(BP),and body mass index(BMI)in the community-managed patients with type 2 diabetes in Jiangsu and to provide the basis for better management of type 2 diabetes in communities. Methods From December 2013 to January 2014,20 053 patients with type 2 diabetes and have received disease management according to the National Basic Public Health Service were recruited in Changshu County of Suzhou City, Huai'an and Qinghe Districts of Huai'an City. Questionnaire survey, anthropometric and laboratory measurements were conducted. According to the Chinese guidelines for type 2 diabetes prevention and treatment(2013),the control levels of blood glucose,blood lipid,BP, and BMI were assessed. Results Among 20 053 patients with type 2 diabetes,the proportions for controlled fasting plasma glucose(FPG) and HbA1Cwere 31.4% and 41.9% respectively,and 25.3% of the patients simultaneously achieved goals of FPG and HbA1Ccontrol. There were 23.9%,55.7%,75.5% and 24.2% of the patients met goals for total cholesterol (TC), triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), and low-density lipoprotein-cholesterol(LDL-C), respectively. Only 10. 3% of the patients achieved all the 4 targets of blood lipid. Furthermore,there were 25.4% and 35.9% patients achieved BP and BMI targets respectively,and the control rates for BP and BMI of females were higher than those of males(all P<0.05). Less than 1% of the patients had all eights indices controlled at target levels. Conclusions The achievement of comprehensive targets among community patients with type 2 diabetes remains poor in Jiangsu. Follow-up and management of type 2 diabetes should be strengthened in communities,health education and comprehensive intervention on disease complications should also be reinforced accordingly.

Association between smoking/smoking cessation and glycemic control in male patients with type2 diabetes / 中华流行病学杂志

Objective To explore the association of smoking and smoking cessation with glycemic control in male patients with type 2 diabetes. Methods From December 2013 to January 2014, a total of 7763 male patients with type 2 diabetes, who received national basic public health service in Changshu county of Suzhou city, Huai'an and Qinghe districts of Huai'an city, Jiangsu province, were recruited by cluster sampling. Questionnaire survey and anthropometric measurements were conducted, and fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) levels were measured. Multiple linear regression model was used to evaluate the association of smoking and smoking cessation with glycemic control. Results The prevalence of current smoking was 45.5%in male patients with type 2 diabetes. The levels of FPG and HbA1c increased with number of cigarettes smoked per day compared with non-smokers (P<0.001). Among patients with drug treatment, the average increase of HbA1c level in current smokers with smoking duration ≥30 years and smoking index ≥40 pack-years were 0.27% (95%CI: 0.05%-0.49%) and 0.38% (95%CI: 0.23%-0.53%),respectively. FPG and HbA1c level decreased obviously with smoking cessation years among former smokers (P<0.05). Among the patients receiving no drug treatment, no dose-response relationships were observed between smoking duration, smoking cessation years and levels of FPG and HbA1c. Conclusion Cigarette smoking was negatively related with glycemic control in male type 2 diabetes patients, especially in patients with drug treatment. Smoking cessation may be beneficial for glycemic control. Smoking cessation should be encouraged for diabetes patients as early as possible.

Results The contents of guanosinein in peels of three strains of Trichosanthes kirilowii Maxim. were 0.159 4, 0.159 6, 0.134 1 mg/g, respectively;the contents of adenine were 0.097 1, 0.127 9, 0.093 4 mg/g, respectively. Conclusion There were significient differences in the contents of adenine among three strains of Trichosanthes kirilowii Maxim.. Strain Ⅱ is with higher level of guanosine and adenine, which implies that the breeding of the Chinese medicinal materals is one way to improve the quality of Trichosanthis Exocarpium.

Relationship between central obesity and clustering of cardiovascular risk factors in adults of Jiangsu province / 中华心血管病杂志

<p><b>OBJECTIVE</b>To explore the relationship between central obesity and cardiovascular risk factors and their clustering in adults of Jiangsu province.</p><p><b>METHODS</b>Multi-stratified clustering sampling method was used to sample 8 400 residents aged 18 years and over from 14 diseases surveillance units in Jiangsu province from October to December 2010. Information was obtained with face-to-face interview, physical examination and laboratory testing. A total of 8 380 residents finished the study protocol and their data were analyzed. Central obesity was defined as waist circumference ≥ 85 cm in males or ≥ 80 cm in females. Following complex weighting of the samples, level and proportion of cardiovascular risk factors in group with different waist circumference were analyzed.</p><p><b>RESULTS</b>The prevalence of central obesity among adults in Jiangsu province was 46.2%, the proportion of males and females was 46.4% and 46.1%, respectively (P > 0.05). The prevalence of center obesity varied significantly in residents with different age, area, education and occupation (all P < 0.01). The level of systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein cholesterol and low density lipoprotein cholesterol was also significantly different in residents with different degree of waist circumference (all P < 0.01). The prevalence of hypertension, diabetes, dyslipidemia and clustering of cardiovascular risk factors increased in proportion to increasing waist circumference (all P < 0.05). Multivariate logistic regression analysis showed that the risk of hypertension, diabetes, dyslipidemia and clustering of cardiovascular risk factors was 2.2 (OR = 2.2, 95% CI: 2.0-2.4) and 4.7 (OR = 4.7, 95% CI: 3.9-5.7); 2.1 (OR = 2.1, 95% CI: 1.7-2.5) and 3.8 (OR = 3.8, 95% CI: 3.2-4.5); 2.3 (OR = 2.3, 95% CI: 1.8-2.9) and 4.1 (OR = 4.1, 95% CI: 3.2-5.3); 3.4 (OR = 3.4, 95% CI: 2.9-3.9) and 8.0 (OR = 8.0, 95% CI: 6.2-10.2) fold higher in residents with mild and severe central obesity than residents without central obesity.</p><p><b>CONCLUSIONS</b>The extent of central obesity positively correlates with the prevalence of cardiovascular risk factors and their clustering in adults of Jiangsu province. Comprehensive interventions on obesity serve as an important tool to reduce the cardiovascular risk in adult Jiangshu residents.</p>
