Objective To investigate the relationship between maternal serum lipid levels and newborn weight in pregnant women with single positive diabetic screening test. Methods On the basis of 75 g oral glucose tolerance test (OGTT), 406 pregnant women during 24-28 gestational week whose 50 glucose challenge test (GCT)≥7.8 mmol/L were separated to gestational diabetes mellitus (GDM) group with 115cases, gestational impaired glucose tolerant (GIGT) group with 60 cases,and GCT (+) group with 231 cases.The serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol(LDL-C), apolipoprotein A1 (ApoA1) and apolipoprotein B (ApoB) were measured at the same time. Results Serum TG concentration was significantly higher in GDM group than that in GIGT group and GCT(+) group(P＜0.01).The level of HDL-C, ApoB in GDM group were lower than those in GIGT group and GCT(+) group (P＜0.01). In the 231 women with positive diabetic screening but normal glucose tolerance who delivered at term, the incidence of macrosomia was significantly higher in those with TG levels higher than 3.5 mmol/L (25.0%, 11/44) than in mothers who TG levels were lower than 3.5mmol/L (11.2%, 21/187) (P=0.017). Multiple regression analysis (stepwise) showed that the independent risk factors of macrosomia was the level of TG and ApoB (F=7.677,P=0.006;F = 7.842,P = 0.001 ).Conclusion Among pregnant women with single positive diabetic screening test,maternal serum TG and ApoB are independently associated with neonatal birth weight.

In order to enhance their core competitiveness,hospitals will deal with medical service suppliers,patients,counterpart hospitals and other stakeholders constantly.Such multiple value activities constitute a patient-oriented and hospital-centered value group.Hospitals have to constantly meet the demand of patients in the provision of medical services,and patients will be satisfied through their own participation in medical activities,thus realize the increase of their value.The pattern of mutual value creation between hospitals and patients forms the new hospital-patient relationship.It is an important condition for the hospitals to gain competitive advantages in the medical service provision through the two models of value maximization and organization minimization,and is also profitable for the formation of a harmonious relationship between doctors and patients.

OBJECTIVETo investigate the clinical value of pleural biopsy in the etiological diagnosis of pleurisy in children.

METHODTotally 213 cases with pleurisy, who underwent pleural biopsy and hospitalized in Children's Hospital of Chongqing Medical University from January 2007 to April 2014 were enrolled into this study. Clinical symptoms, imaging manifestations, pleural fluid characteristics, the results of pleural biopsy and postoperative complications were retrospectively analyzed to evaluate the clinical value and security of pleural biopsy in making the etiological diagnosis of pleurisy.

RESULT(1) Of the 213 cases, 144 were boys and 69 were girls, their mean age was (6. 5 ± 4. 1) years. (2) Two hundred and thirteen patients had a surgical pleural biopsy under general anesthesia, the cause of 97 cases (45. 5%) were made clear by histopathological examination, including 35 purulent pleurisy, 55 tuberculous pleurisy and 7 paragonimus infection. For the remaining 83 (41. 3%) cases a final diagnosis was made based on the full analysis of clinical data, including 63 cases of purulent pleurisy, 3 cases of tuberculous pleurisy and 17 cases of paragonimiasis pleurisy but for 33 patients no exact cause was found at the end. (3) The mean operating time of the biopsy was (1. 4 ± 0. 6) hours. Seventy one (33. 3%) patients required blood transfusion during or after the operation. Thirty one (14. 6%) cases used the ventilator after surgery, and the ventilator supporting time was (6. 6 ± 5. 8) hours on average. The wound healing reached grade A in 200 cases (93. 9%), grade B in 13 cases (14. 6%). Postoperative complications included pneumothorax in 92 cases (43. 2%), subcutaneous emphysema in 18 cases (8. 5%), bronchopleural fistula in 3 cases(1. 4%). The average days of hospitalization was (17. 7 ± 7. 1) d.

CONCLUSIONPleural biopsy is of great diagnostic value in the etiological diagnosis and differential diagnosis of pleurisy in children, and it is considered reasonable to be used in the clinical practice when appropriate.

Objective To investigate the distribution and antimicrobial resistance of pathogens isolated from lower respiratory tracts of early onset and late-onset ventilator-associated pneumonia (VAP)patients in intensive care unit. Methods A retrospective analysis was performed on data collected from1324 patients admitted to the ICU in the Third People' s Hospital in Wenzhou from July 2008 to December 2011 who received invasive mechanical ventilation.Patients were divided into early-onset pneumonia group (EOP,≤ 4 d mechanical ventilation ) and late-onset pneumonia group (LOP, ＞ 4 d mechanical ventilation).x2 or t test was performed to compare the pathogen distribution and antimicrobial resistance between two groups.Results In 1324 patients,552 (41.7％) suffered from VAP,including 74 ( 5.6％ )patients with EOP,382 (28.9％) patients with LOP,and 96 (7.3％) patients with both EOP and LOP.The top 6 pathogens in EOP group were Acinetobacter baumannii ( 72,22.6％ ),Pseudomonas aeruginosa (45,14.1％ ),Klebsiella pneumoniae (32,10.0％ ),Canidia albicans ( 31,9.7％ ),Burkholderia cepacia ( 31,9.7％ ) and Staphyloccocus aureus ( 28,8.8％ ) ; and in LOP group were Acinetobacter baumannii (235,21.2％ ),Canidia albicans (201,18.1％ ),Pseudomonas aeruginosa ( 111,10.0％ ),Candida glabrata ( 86,7.8％ ),Klebsiella pneumoniae ( 81,7.3％ ) and Staphyloccocus aureus ( 46,4.2％ ).Staphylococcus aureus infection in EOP group was more common than that in the LOP group (x2 =10.780,P =0.002),but the separation rate of Candida albicans in EOP group was significantly lower than that in the LOP group (x2 =12.907,P =0.000).Gram-negative bacteria isolated from EOP or LOP group were both highly resistant to most commonly used antibacterial agents,especially for Acinetobacter baumannii and Pseudomonas aeruginosa strains. Most Staphyloccocus aureus strains were methicillin-resistant strains (EOP:67.9％,19/28; LOP:63.0％,29/46).Canidia albicans and Candida glabrata were sensitive to most antifungal agents.Conclusion For both EOP and LOP groups,the majority of pathogens isolated from lower respiratory tract are Gram-negative bacteria,and drug resistance is serious.

Objective To investigate the correlation between microalbuminuria (MAU) and obesity and its indexes, including BMI, waist circumference(WC), and waist-to-hip ratio(WHR) , among partial community population in Beijing. Methods A total of 2080 subjects who took physical examination in Beijing, including 810 men and 1270 women with a mean age of(50. 9 ± 13. 1 )years, were enrolled. The informed consent has been achieved from each patients. BMI and WHR were calculated based on collected data of height, weight, WC, and hipline. Urine albumin-creatinine ratio(ACR) within the range of 30-300mg/g was classified as MAU. The subjects were divided into normal albuminuria ( NAU ) group and MAU group. The correlations between MAU and different obesity indexes including BMI, WC and WHR, were analyzed. Results Among the 2080 subjects, there was a positive correlation between BMI (r = 0. 1276,P＜0.01) and ACR, and WC (r = 0.0840, P ＜0.01) and ACR. WHR and ACR was irrelevant ( P ＞ 0. 05 ). In univariate analysis, there was significant difference in BMI ≥ 28 kg/m2 ( OR = 2. 02 ) and WC ≥85 cm (male) or≥80 cm (female) (OR = 1.69 ) between NAU group and MAU group (P ＜ 0. 05 ).There was no significant difference in BMI 24-＜ 28 kg/m2, and WHR ≥0. 90 (male) or ≥0. 85 (female)between NAU group and MAU group( P≥0. 05 ). Multivariate logistic regression analysis revealed that BMI ( OR = 1.06) was an isolated independent risk factor of MAU from age ( OR = 1.01 ), female ( OR = 1.42),systolic blood pressure (OR=1.01), TC (OR=1.93) and HDL-C (OR=0.54). Conclusions Obesity is an independent risk factor of MAU among partial community population in Beijing. The correlation between different obesity indexes and MAU also differs.

Objective To investigate the clinical effect of adductor magnus tendon transposition with arthroscopic in reconstruction medial patellofemoral ligament (MPFL) for the treatment of patellofemoral joint instability of adolescents. Methods Eighteen juvenile patients (21 knees) with patellofemoral joint instability (including chronic patellar dislocation and recurrent patellar dislocation) were treated with adductor magnus tendon transposition for MPFL reconstruction, combined with lateral patellofemoral ligament release. They were followed up for 12- 30 months. The complications, patellofemoral angles and Lysholm scores before and after operation were recorded and compared. Results There was no complications such as wound infection, redislocation, patellofemoral joint instability and epiphyses injured. All patients got excellent knee flexion and extension function. Patella fear tests were all negative. The patellofemoral angles and Lysholm scores after operation were improved significantly than those before operation:(10.3 ± 4.1)° vs. (-3.8 ± 4.9)°, (92.7 ± 3.6) scores vs. (61.5 ±2.4) scores, P<0.01. Conclusions Adductor magnus tendon transposition with arthroscopic in reconstruction MPFL can significantly improve the stability of patellofemoral joints. This is one of the effective methods for the treatment of patellofemoral joint instability of adolescents.

Objective To observe the expressions of thyroid-stimulating hormone receptor (TSHR) protein and mRNA in thyroid gland of lactating rats.Methods Eighty adult Wistar rats (60 females and 20 males),weighting 210-250 g were selected.The 60 female Wistar rats were divided into 6 groups according to their body weight by means of random number table:normal non-pregnant group,lactating for 5,10,15 and 20 days groups and weaning for 5 days group,10 rats in each group.All rats were fed with conventional fodder and tap water freely,and the rats of lactating groups except the normal non-pregnant group cohabited with male rats (3 ∶ 1).Then all rats were killed on the 5th,10th,15th and 20th day after lactation and on the 5th day after weaning to get thyroid tissues.The expressions of TSHR protein and mRNA were determined by immunohistochemical staining and realtime quantitative PCR.Results TSHR protein was expressed in cytoplasm and membrane of rat thyroid follicular cells.The expression of TSHR protein in thyroid gland was significant different statistically between groups (x2 =11.227,P ＜ 0.05); the staining intensity of rat thyroid tissues in the normal non-pregnant gruop (weak,n =2; moderate,n =5; strong,n =3) was stronger than that of rats lactating for 5 days (weak,n =7; moderate,n =3; x2 =5.895,P ＜ 0.05).But the expression of TSHR protein in thyroid tissues in the normal non-pregnant group was not significantly different statistically compared with the expression of TSHR protein in other groups (lactating for 10,15and 20 days) and weaning for 5 days group (all P ＞ 0.05).The expression of TSHR mRNA in thyroid gland was significantly different statistically between groups (F =2.970,P ＜ 0.05); the expression of TSHR mRNA in lactating for 5 days group (0.74 ± 0.13) was lower than that of the non-pregnant group (1.02 ± 0.24,P ＜ 0.05); and the expression of TSHR mRNA in the normal non-pregnant group was not significantly different statistically compared with those of other groups (lactating for 10,15 and 20 days) and weaning for 5 days group (all P ＞ 0.05).Conclusion TSHR is widely expressed in thyroid gland of lactating rats,but relatively lower in early lactation period.
