Objective To investigate characteristics of glucose metabolism of non-obese and obese women with polycystic ovary syndrome (PCOS). Methods From May 2006 to April 2009, 1928 PCOS patients treated in Reproductive Medicine Center of Shandong Provincial Hospital Affiliated to Shandong University were enrolled in this study, which were divided into 901 cases [body mass index (BMI) ≥25 kg/m2] in obese group and 1027 cases in non-obese (BMI < 25 kg/m2) group. The prevalence of type 2 diabetes mellitus (T2DM), oral glucose tolerance test, impaired fasting glucose (IFG), impaired glucose tolerance(IGT) were compared between the two groups. Results (1) Blood glucose levels: at the time of fasting, 30, 60, 120 and 180 minutes, the levels of glucose were (5. 3±1.1), (9. 0±2. 4), (9. 3±4. 4),(7.5±2.8) ,(5.3±1.8)mmol/L in obese group and (5.0±0. 8) ,(8.4±3.5),(8.0±4.2),(6.5±3.2) ,(4. 9±1.6) mmol/L in non-obese group, which all showed statistical difference at every time point (P < 0. 01). (2)The level of insulin: at the time of fasting, 30, 60, 120 min, the level of insulin were (13±7), (81±51), (102±65), (83±63) mU/L in obese group and (8±5) ,(57±35) ,(62±44),(46±39) mU/L in non-obese group, which all showed statistical differenceatevery time point (P <0. 01). However, at time point of 180 minutes, the level of insulin did not exhibit significantly difference between obese and non-obese group (P > 0. 05). (3) The prevalence of abnormal glucose metabolism: the rate of IFG was 4. 98% (96/1928). The rate of abnormal glucose tolerance was 23. 08% (445/1928). The rate of IGT were 13.05% (134/1027) in non-obese group and 24. 20% (218/901) in obese group,which also showed remarkable difference (P < 0. 01). The rate of T2DM were 2. 53% (26/1027) in nonobese group and 7.44% (67/901) in obese group, which reached significant difference (P < 0. 01).Conclusion Abnormal glucose metabolism was observed more frequently in overweight or obese PCOS women.

Objective To study the feasibility of engineering cartilage tissue in a tube lined with epithelium and implanting allogenic chondrocytes into a novel scaffold consisting of chitosan nonwoven cloth coated with poly (DL-lactide-co-glycolide)(PLGA).The focus of the present study is to explore a new way of repairing laryngeal and tracheal defects.Methods Allogenic chondrocytes were obtained from the auricles of 1-month-old rabbits.After being cultured in vitro for three to four passages,the cells were implanted into the scaffolds to form composite grafts and then transplanted into the rabbits.After 6,12,and 18 weeks,the general,histological characteristics were investigated.Results The cobweb-like matrix was observed approximately 1 week after the chondrocytes had been implanted into the scaffolds.At 6 weeks,the matrix was secreted,and there were immature chondrocytes in the grafts.At 12 weeks,the allogenic cartilage in the tube lined with epithelium had been created.Chondrocytes were almost mature and the lacunae had formed.At 18 weeks,the neocartilage was similar to native cartilage.Conclusion It is feasible to fabricate allogenic cartilage in a tube lined with epithelium by implanting allogenic chondrocytes into a novel scaffold made of chitosan nonwoven cloth coated with PLGA.

ObjectiveTo explore a minimally invasive,reliable,and efficient method for endotracheal intubation to instill lipopolysaccharide (LPS) for preparation of acute lung injury (ALI) in mice.MethodsA total of 80 BALB/C mice was randomly selected into LPS group ( n =40) and control group (Normal saline,NS; n =40).After a successfully endotracheal intubation,each mouse was instilled by LPS (3 mg/kg) in LPS group,and NS ( 1.5 ml/kg) in NS group,respectively.The one-time success rate and final success rate of the endotracheal intubation,and survival rate were recorded.After 24 hours,the total number of cells in bronchoalveolar lavage fluid (BALF) of left lung was counted with light microscope.The cells were classified and counted after Wright's stain.Total protein concentration in BALF was assayed with a BCA kit.Wet/dry value was calculated after the lung became dry.Artery blood PaO2 was tested and the oxygenation index was counted.ResultsCompared to NS group,the LPS group had the one-time success rate 92.5％,and the final success rate 100％,survival rate 100％,the total number of cells [ ( 10.82±3.51) ×105/mlvs (0.72±0.52)×105/ml.t =-6.294 P ＜0 01]the rate of polymorphonulear leukocytes in total cells [ (93.93 ± 1.77) ％ vs (2.2 ± 0.91 ) ％,t =- 105.565,P ＜ 0.01 ],the rate of mononuclear leukocytes in total cells[ (6.07 ± 1.77)％ vs (97.8 ±0.91 )％,t =- 105.565,P ＜0.01 ],total protein concentration[ (0.49 ± 0.13 ) mg/ml vs (0.29 ± 0.11 ) mg/ml,t =- 2.823,P ＜ 0.05 ],W/D ratio(4.60 ±0.18 vs 4.16 ±0.25,t =-4.793,P ＜0.01 ),PaO2[ (68.57 -±7.23)％ vs(87.00 ±6.33 )％,t =4.571,P ＜ 0.01 ],and oxygenation index [ (326.53± 34.43 )mmHg vs (414.29 ± 30.16)mmHg,t =4.571,P ＜0.01 ].ConclusionsImproved method for endotracheal intubation has high success rate and minimal injury,and instillation of LPS (3 mg/kg)can induce mice ALI successfully.
