Aim To study the effects of preconditioning with desflurane, sevoflurane and isoflurane on adenosine triphosphate (ATP) in anoxia-reoxygenation myocardial cells. Methods Rat ventricular myocytes, cultured for 4~5 days, were randomly allocated to five groups: Control group, anoxia-reoxygenation group and groups preconditioned with 1.5 MAC desflurane, sevoflurane or isoflurane following anoxia-reoxygenation. The content of intracellular ATP ,the activities of lactic dehydrogenase(LDH) and creatine kinase(CK), and the cell viability were measured at the end of experiment.Results Preconditioning with 1.5 MAC desfllurane, sevoflurane or isoflurane significantly attenuated the great reduction in ATP and cell viability and the increase of LDH and CK caused by anoxia-reoxygenation. There was a positive correlationship between ATP and cell viability,and a negatiue correlationship between LDH and CK (r was 0.83, -0.87 and -0.82 respectively, P

Objective To investigate the relationships between serum concentration of RBP-4 and the parameters of inflammatory, lipid metabolism, insulin resistance in patients with T2DM. Methods 71 patients newly diagnosed with T2DM and 34 subjects with normal glucose tolerance (NGT) were enrolled in this cross-sectional study. Additionally, another subset analysis was performed. Subjects were divided into normal weight (NW) and overweight or obesity (OW/OB) group on the basis of BMI. Serum RBP-4 was measured with ELISA. Serum concentrations of hs-CRP, free fatty acids (FFA), triglyceride (TG), total cholesterol (TC) and insulin were measured in fasting status. Insulin resistance was assessed by HOMA-IR. Results Ln (HOMA-IR) and the concentrations of TG, FFA, In(hs-CRP) in T2DM were significant-ly higher than that of NGR group[1.20±0.38 vs 0.76±0.34,(2.74±2. 20)mmol/L vs (1.88±1.41),(0. 80±0. 29)mmol/L vs (0.61±0.22)retool/L,0.62±1.00 vs -0. 17±1.07] . InRBP-4 showed a positive relationship with In (HOMA-IR) ( r =0. 382, P <0. 05), but no association with TC, TG, FFA and In(hs-CRP). In the group of T2DM, InRBP-4 showed a positive relationship with FFA ( r =0. 242, P <0.05) and In (hs-CRP) ( r =0.346, P <0.01), but no association with TC, TG and In (HOMA-IR). There were no relationships between InRBP-4 and In (HOMA-IR), TC, TG, FFA and In (hs-CRP)in NW, while in OW/OB group, InRBP-4 showed a positive relationship with In (HOMA-IR) ( r =0. 290,P < 0. 05 ) and In (hs-CRP) ( r = 0. 295, P <0.05 ), but no association with TC, TG and FFA. In a mul-tiple linear regression analysis, In( hs-CRP), TC, TG, FFA or In(HOMA-IR) was not the independent de-terminant of InRBP-4 in any group. Conclusion In patients with T2DM, InRBP-4 is positively correlatedwith In (hs-CRP) and FFA, and it may be a new marker of inflammation.

Acetabular is an important human joint for weight bearing. Quadrilateral plate is a crucial structure of medial acetabulum with special morphology and important function. Quadrilateral plate fractures are common fracture in acetabulum. Quadrilateral plate fracture is hard to expose and reduction because it is in the medial of acetabulum. At the same time,the bone in the quadrilateral plate is not easy to fixed for thinning bones and adjacent to the articular cavity. The operator should know well about the anatomy and choose the suitable internal fixation. After quadrilateral plate fractures, the femur head maybe displace medially even break into pelvis. That make reduction and treatment always be a challenge. With different kinds of fractures,the efficacy of treatment is not the same. This paper intend to review the relation of anatomic features,approaches, internal fixations, key point of treatment and efficacy.

Objective To analyze the clinical characteristics of narcolepsy in children with obesity,and to e-valuate the impact of obesity on narcoleptic children clinically. Methods Forty cases first diagnosed as narcolepsy were recruited in the study who to see doctors at the Department of Neurology,Children's Hospital of Capital Institute of Pediatrics,from July 2012 to January 2015. According to diagnostic criteria for obesity by the body mass index(BMI) growth curve for the Chinese children and adolescents,they were divided into the obese group and the nonobese group. The general clinical data of 2 groups were analyzed,and the related metabolic indexes and the whole night polysomnog-raphy(PSG)of 2 groups were studied. Results In this group,male versus female 3: 1,obesity was found in 21 cases (52. 5% )and nonobesity was found in 19 cases(47. 5% )from the samples. The mean BMI of all patients was (21. 55 ± 3. 11)kg/ m2 . The average BMI of the obese group was(23. 09 ± 2. 46)kg/ m2 ,and BMI of the non - obese group was(19. 85 ± 2. 89)kg/ m2 . Obese children were younger at the onset of disease and by the time of diagnosis age [(7. 94 ± 2. 22)years old,(8. 76 ± 2. 36)years old]than nonobese children[(10. 75 ± 3. 10)years old,(12. 51 ± 2. 88)years old]. The fasting blood glucose and blood lipid in all patients were normal,and there was no significant difference between 2 groups. The total sleep time,sleep efficiency and the ratio of rapid eye movement(REM)phase of the obese group[(397. 45 ± 53. 76)min,(68. 70 ± 8. 90)% ,(18. 37 ± 4. 39)% ]were significantly lower than those of the non - obese group[(449. 95 ± 86. 49)min,(76. 58 ± 13. 60)% ,(22. 19 ± 6. 34)% ]. According to the sleep structure,the percentage of stageⅠnon rapid eye movement(NREM)sleep in the obese group[(20. 90 ± 6. 38)% ] was more than that in non - obese group[(16. 26 ± 4. 22)% ]. There was no difference between the percentage of stageⅡNREM sleep in the obese group[(42. 59 ± 5. 52)% ]and the non - obese group[(38. 54 ± 8. 74)% ]. Stage Ⅲ + Ⅳ(slow wave sleep)NREM sleep ratio in the obese group[(18. 14 ± 6. 97)% ]was significantly lower than that in the non - obese group[(22. 60 ± 5. 69)% ]. Conclusions Obesity is one of the most common comorbids in narcolepsy, which affects more than 50% of narcoleptic children,mostly younger at disease onset. The narcolepsy children with obe-sity has total sleep time decreased,sleep efficiency reduced and sleep structure disorder is more obvious. To improve the realization of obesity in narcolepsy children and early treatment is the key to the success of the therapy.

This paper presents the results of the gross dissection and the histologic observation on the thyroid and parathyroid glands of Rhinopithecus. Specimens used in the studies are composed of R. roxellanae (1 (?), subad.), R. bieti (2 ♀♀, ad.; 1 ♀,juv.) and R. brelichi(2(?)(?),ad.). Besides the position and shape of the gross anatomy of the thyroid and parathyroid glands, attention was paid to the cellular types of the parathyroid glands. Material used for the histologic investigation is stained with HE and the modified Mallory-Azan methods and observed under the light microscopy. The principal results are summarized as follows:1. The thyroid gland consists of two lateral obes. The dimension of the gland measured 18.0?9.0, 15.0?8.0 and 14.0?6.0 mm. in bieti;23.0?9.0 mm. in roxellanae; 25.0?9.0 and 30.0?1.0 mm in brelichi; and one isthmus measures 3.0?10.0, 2.0?10.0 and 2.0?6.0 mm. in bieti; 4.0?6.0 mm. in roxellanae; 5.0?12.0 and 5.0?14.0 mm. in brelichi.The total weight of the gland is 1.0, 0.5 and 0.3g in bieti; 0.9g in roxellanae; 0.9 and 1.8g in brelichi.The isthmus connects the lower edges of two lateral lobes. There is no pyramidal lobe.2. The blood supply is derived from the superior thyroid arteries. There are no inferior thyroid arteries in three kinds. The thyroid venous drainage is by the superior and inferior thyroid veins, there is no median thyroid vein.3. The sizes and shapes of the thyroid vary with species. Each animal possesses two parathyroid glands, one of each side, but their position is also variable in the different animals.4. The follicular epithelium of the thyroid contains two cellular types, viz. the typical follicular epithelial cells and C cells.5. The parathyroid gland of Rhinopithecus is histologically similar to that of Macaca mulatta and man, which contains four basic cellular elements. There is an intermediary cellular type probably a variant of the oxyphil cells.6. Grey blue granules are present in the pale oxyphil cells of the parathyroid glands of both brelichi and bieti.7. There are less oxyphil cells among the parenchymal cells of the parathyroid gland in the subadult roxellanae than in both bieti and brelichi.
