This paper presented the effects of experimental hyperinsulinemia on the main apolipoproteins (At, B) and on tbe process of reverse cholesterol transport in rabbit, which consisted of 1) uptake of cholesterol from peripheral tissue by HDL; 2) cholesterol esterification and 3) cholesterol ester transfer. The results showed that insulin could significantly decrease both serum and lymph Apo A1 levels and inhibit all the three steps of reverse cholesterol transport. The larger the dose of insulin, the greater the effects. Apo B did not seem to be influenced by insulin. It was further demonstrated by a series of statistical analyses that insulin had both direct and indirect inhibitory actions, to different extent, on each of the three main steps of reverse cholesterol transport.

Enteric nervous system consists of myenteric and submucous plexuses. Myenteric plexus mainly innervates the enteric motion; submucous plexus modulates the gastrointestinal secretion and local blood flow. P2 (ATP) receptors exist in both of the above plexuses and play an important role under physiological and pathophysiological conditions. This article reviews the distribution, function and pharmacological characteristics of different P2 receptors, in an effort to provide new evidence for studying the role of P2 receptors in the diagnosis and therapy of enteric diseases.

Objective:To study the effect of increased expression of Fas on the killing of ? cells Methods:The level of Fas expression and apoptosis of human ? cells strain (NIT) were detected by FACS Results:There is no Fas expression on NIT But Fas expression can detected by culturing NIT with IFN ? and/or TNF ? The apoptosis of NIT induced by sFasL and anti Fas correlates with the level of Fas expression Conclusion:Fas expression induced by cytokine may represent a factor for the initiation of ? cells destruction

Objective To analyze the serum level of 25-hydroxy vitamin D [25-(OH) D] in pregnant women in Nanjing and its relationship with age,gestational week,pre-pregnancy body mass index (BMI) and season,so as to provide some guidance on clinical application of vitamin D measurement and supplementation.Methods 880 pregnant women (in 21-36 gestational weeks) regularly visiting antenatal clinic in Obstetrics and Gynecology Hospital Affiliated to Nanjing Medical University were selected from January to December 2015.Their serum 25-(OH)D concentrations were measured by enzyme-linked immunosorbent assay (ELISA).Results The mean serum 25-(OH) D concentration in these pregnant women was (42.03 ± 19.22) nmol/L and sufficient in only 42 (4.77％).Vitamin D levels showed seasonal variation (P =0.0164),with the levels in summer [(44.61 ±23.57) nmol/L] and autumn [(43.43 ± 19.31) nmol/L] being higher than spring [(39.68 ± 16.91) nmol/L] and winter [(39.65 ± 13.36) nmol/L].There was no statistically significant difference in serum vitamin D level among different gestational weeks (P =0.929 4).There was statistically significant difference in serum vitamin D level among different age groups (P =0.038 3).Vitamin D level was not associated with pre-pregnancy BMI.Conclusions Vitamin D deficiency is highly prevalent among pregnant women in Nanjing.We suggest vitamin D testing be carried out more actively.

Objective To explore the feasibility of artificial silastic framework(SF)in repair of large area of tracheal wall defects.Methods Twenty healthy adult dogs with tracheal defects for 2.5 cm?6.0 cm-3.0 cm?6.0cm were randomly and equally divided into experimental group(repaired with SF combined with sternohyoid fasciae)and control group(repaired with T-silastie tubule combined with sternohyoid fascial flap).After the operation,the animals were sacrificed at the 4th,8th,16th,24th, and 48th weeks respectively for harvesting the tracheae that were used for tracbeoscopically observing in- flammatory reaction of the repaired defect area and light microscopically observing epithelium healing on the repaired defect area.Results In the experiment group,the repaired trachea was smooth,without proliferation of granulation;and at the 8th week,the repaired defect area was covered with epithelial cells,with good functional recovery of respiration,phonation and deglutition.In the control group,there was obvious proliferation of granulation on the tracheal surface near anterior and posterior ends of T-silas tic tubule.The animals were under asphyxia to die with extraction of T-silastic tubule.Conclusions SF has excellent tracheal skeletal function.In the meantime,SF combined with sternohyoid fasciae is a simple but effective method for repair of large area of tracheal wall defects.

BACKGROUND:Since cannulated screw has been applied to femoral neck fracture, it is not uncommon that the screw wear penetrates or refunds. What factors affect the stability of cannulated screw for treatment of femoral neck fractures in adults remains unclear. ＜br> OBJECTIVE:To explore factors related to internal fixation failure by cannulated screws in treatment of adult femoral neck fracture and improve the stability of the adult femoral neck fracture by cannulated screws. ＜br> METHODS:A total of 92 adult patients of femoral neck fracture were treated by cannulated screws in our department between June 2007 and June 2011. Their data were retrospectively analyzed. According to clinical information and fol ow-ups, we selected factors such as age, gender, Garden type of fracture, preoperative skeletal traction, timing of surgery, Garden index, standards of pedicle screws, pedicle screw shapes, partial weight bearing time and postoperative complications, which may affect the success rate of cannulated screws for ＜br> treating femoral neck fracture. The selected factors were then grouped and assigned, after unrelated factors were excluded by one-way χ2 analysis, multiariable Logistic regression analysis was performed. ＜br> RESULTS AND CONCLUSION:The involved 92 patients were fol owed up for 18-72 months. According to Harris assessment criteria, hip function was excellent in 28 cases, good in 25 cases, fair in 17 cases, and poor in 22 cases at the final fol ow-up, the excellent and good rate was 58%. Radiographic results showed that, the patients were divided into two groups according to the presence of the displacement, GardenⅠ (n=22) and GardenⅡ (n=29) as a group, and Garden Ⅲ (n=25) and Garden Ⅳ (n=16) as the other group, the fixation failure rate was 12%and 39%, respectively. In normol and abnormal Garden Index groups, the fixation failure rate was 16%and 59%, respectively. In nail position standards and non-attainment standards groups, the fixation failure rate was 19%and 70%, respectively. In the complication and non-complication groups, the fixation failure rate was 14%and 55%, respectively. These factor groups showed significant differences (P＜0.05). Multiariable Logistic regression analysis showed that, Garden type of fracture, Garden index, standards of pedicle screws, and postoperative complications are the risk factors for internal fixation failure using cannulated screws in treatment of the adult femoral neck fracture.

AIM:To contrast analysis of postoperative variation of corneal posterior surface heights after Femtosecond LASlK ( FS - LASlK ) and small incision lenticule extraction ( SMlLE) for high myopia.
●METHODS: Sixty-seven cases of high myopic patients (132 eyes) operated with laser corneal refractive in our hospital from May to Dec. in 2015 (-6. 00D≤spherical equivalent degree≤-10. 00D) were selected and divided into FS-LASlK group and SMlLE group. The thickness of corneal flaps at FS-LASlK and the thickness of map at SMlLE were designed to be 110μm. Corneal posterior surface heights were examined by Pentacam at preoperation, postoperative 3 and 6mo after FS-LASlK and SMlLE operation. Surface height changes after preoperative, postoperative 3 and 6mo were compared by measuring Pentacam corneal analysis system.
●RESULTS: Six months after operation, the FS-LASlK posterior corneal surface height was 6. 47 ± 1. 65mm, significantly higher than 5. 20 ± 1. 32mm before operation. SMlLE posterior corneal surface height was 6. 40 ± 1. 33mm, significantly higher than 5. 18 ± 1. 25mm before operation, the differences were statistically significant( P<0. 05). Six month after surgery, two methods of corneal surface height variation obtained was 1. 29 ± 1. 28mm and 1. 22 ± 0. 89mm, there was no significant difference ( P>0. 05).
●CONCLUSION:After FS-LASlK and SMlLE, the corneal posterior surface is protrusive. FS - LASlK is slightly obvious than SMlLE in early period. The stability of the posterior surface is better after SMlLE.
