Objective To explore the levels of serum leptin and insulin and their relationships with growth and development in premature infants.Methods The serum leptin and insulin concentrations of 37 premature infants were examined by the radioimmunoassay(day 1 and day 10,respectively),and anthropometric measurements were performed at birth.The blood sugar and triglyeride,cholesterol were tested at the same time.Twenty full-term newborn without severe diseases were controlled in 24 h after delivery and the level of leptin and insulin of them were detected,too.The results were analyzed by SPSS 10.0 software.Results The leptin and insulin levels in preterm infants were significantly lower than those in full-term infants[(6.45?2.24)?g/L vs(8.56?1.33)?g/L,(5.84?1.07)IU/L vs(10.85?5.24)IU/L Pa0.05).Serum leptin was positive correlation with serum insulin(Pa0.05).Conclusions Serum leptin and insulin can be the markers that reflect intrauterine nutrition status of preterm infants and the growth and development of fetus.A dipoinsular axis may be functional before 34 weeks gestation without maturity.The changes of leptin and insulin concentrations are useful for metabolism and growth in preterm infants.

AIM: To analyze the application on frequency domain optical coherence tomography ( OCT ) technology of pathologic myopia optic disc neurosensory retinal thickness changes and its relationship with axis oculi, sex and age, and help for the early diagnosis of pathological myopia and primary open angle glaucoma.
METHODS:Collected 96 eyes of normal eyes ( axis oculi 23-24mm) and 153 eyes of pathologic myopia eyes ( axis oculi 25-27mm 80 eyes, >27mm 73 eyes). We measured the thickness of nerve fiber layer of the optic disc by OCT and analyzed their relationship with axis oculi, sex and age with multiple linear regression analysis.
RESULTS: The observation group showed significant smaller average thickness of peripapillary, superior, inferior, nasal than the control group ( P<0. 05 ); the difference in the temporal quadrant between the groups were no statistically significant differences (P>0. 05); The partial correlation coefficient of peripapillary average thickness of nerve fiber layer and axis oculi was -1. 31, gender was 5. 21, age was -0. 12.
CONCLUSION:The thickness of nerve fiber layer of the optic disc in the pathologic myopia eyes are decreased than normal eyes, axis oculi, sex and age are influenced factors. The pathologic myopia patients should use different index combined with optic nerve fiber layer thickness decreased to help for the diagnosis of early primary open angle glaucoma.

A test was conducted to examine the effect of several electron donors such as glucose, sodium acetate, Fe0, Fe0+glucose and Fe0+sodium acetate on reductive dechlorination of 2,4-dichlorophenol (2,4-DCP) through inoculating the unacclimated anaerobic mixed bacteria. The optimum condition and sus-tainability of Fe0 as electron donor was also been discussed. The results showed that, Fe0+glucose enhanced the dechlorination of contaminant effectively compared to glucose. Sodium acetate, Fe0 and Fe0+sodium acetate were all effective electron donors and Fe0 was the optimum, the optimum initial pH was 8.0 and quantity of added Fe0 was 2.0 g/L. 4-CP was the mainly intermediate product for 2,4-DCP dechlorination. Fe0 could support the electron for reductive dechlorination of 2,4-DCP continuously. In contrast, when so-dium acetate as electron donor, the effect of dechlorination was inferior to Fe0 with the consumption of sodium acetate.

OBJECTIVETo elucidate the molecular mechanism of Wendan Tang in prevention of lipid metabolism disorder in adult rats.

METHODOn the basis of hyperlipidemia rat models, triglycerides (TG), total cholesterol (TC) in serum, activities of lipase (LA), lipoprotein lipase (LPL), hepatic lipase (HL) in liver, parts of hemogram and hepatic LDLR mRNA levels were investigated 21 days after the feeding of atherogenic diet.

RESULTWendan Tang significantly reduced the serum TG, TC and increased the activity of LPL and LA, but caused no chang in HL. The result of RT-PCR test showed that high fat and high cholesterol feeding could significantly induce the reduction of LDLR mRNA levels, while Wendan Tang could increase hepatic LDLR density.

CONCLUSIONWendan Tang can prevent disorder of lipid metabolism by regulating TC, TG, LDL-c through upregaulation of LDLR transcription level and improving antioxidant ability.

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

OBJECTIVETo evaluate the effect of cemented long stem bipolar prosthetic prosthesis in the management of unstable intertrochanteric fractures in the elderly.

METHODSA retrospective analysis of 23 elderly cases of uncemented long-stem prosthetic replacement for unstable intertrochanteric fractures was conducted. Of the 23 elderly patients, 6 had type IIA fracture by Evans-Jenson classification, 11 had type IIB fractures, and 6 had type III fractures.

RESULTSOne patient died due to severe respiratory failure during the follow-up period. The patients were followed up for 6 to 10 months (mean 15 months), and no dislocation, infection, loosening or sinking of the prosthesis was found in the followed-up cases with a Harris score reaching 84.8.

CONCLUSIONCemented long-stem bipolar prosthetic prosthesis replacement is effective for management of unstable intertrochanteric fractures in the elderly.

OBJECTIVETo investigate the characteristics of supracondylar fracture of humerus in children and to explore the effect of closed reduction and internal fixation at radial side on the fracture.

METHODSThe children with fractures of Gartland type II and type III in our hospital from June 2010 to June 2013 were reviewed. There were 28 males and 7 females, ranging in age from 1 year and 1 month to 2 years and 6 months, with an average of 2 years and 1 month. According to Gartland classification, 19 cases were type II, 16 cases were type III. There were 3 patients with radial nerve injuries, and 5 patients with anterior interosseous nerve injuries. There were no vascular injuries. All the patients were treated with closed reduction and three Kirschner fixation at the radial side, followed by the plaster external fixation with elbowed flexion at 90 °. The X-ray examination was performed at the second day after operation. The joint function exercise began about at 2 to 3 weeks after operation when the plaster fixation was removed, and opportune time for removal of Kirschners depends on the situation of fracture healing. The operation time, nerve recovery, and the elbow joint function were observed.

RESULTSAll the children were followed up, and all the fractures had bony union. According to Flynn score system at the final follow-up, 28 patients got an excellent result, 4 good, 1 poor and 2 bad.

CONCLUSIONThree Kirschner fixation at the radial side for the treatment of supracondylar fracture of humerus has advantages of minimally invasive, shorter time of hospitalization, simple removal of the internal fixation and reliable therapeutic effects.
