Objective To investigate the clinical efficacy and safety of sitagliptin combined with metformin in treating patients with type 2 diabetes with non-alcoholic fatty liver diease (NAFLD).Methods Sixty-five patients with type 2 diabetes with non-alcoholic fatty liver admitted into our hospital from June 2012 to June 2015 were randomly divided into two groups.Thirty-three patients in control group were treated with metformin only,and thirty-two patients in observation were treated with sitagliptin combined with metformin.The changes in body mass index (BMI),fasting plasma glucose (FPG),2-hour postprandial glucose (2hPG),Hemoglobin Ale (HbAlc),homeostasis model assessment of insulin resistance (HOMA-IR),and liver function index including that aminopherase of alanine acid (ALT),aminopherase of aspartic acid (AST),gamma-glutamyl transterase (GGT),triglyceride (TG),and total cholesterol (TC) were detected before and after 16 weeks of treatment.And the total effective rate and safety were analyzed and compared.Results After treatment,HOMA-IR,FPG,2hPG,HbA1c,ALT,AST,GGT,TG,and TC were remarkable improvement (P ＜ 0.05),and HOMA-IR,HbA1c,AST,ALT,GGT,and TG were significantly better than those of control (P ＜ 0.05).Additionally,the total effective rate in observation group with 90.9％ was significantly higher than that of control group with 42.4％ (P ＜ 0.05).And difference in incidences of adverse effect between observation group with 15.6％ and control group with 9.1％ were not significant.Conclusion Sitagliptin combined with metformin treatment had a good ability on treating patients with type 2 diabetes with NAFLD by improvement of metabolic syndrome and liver function.

Objective To evaluate the clinical safety and efficacy of Cheatham-Platinum(CP)covered stent in treatment of aortic coarctation.Methods The therapeutic efficacy was retrospectively analyzed in 15 patients with aortic coarctation who were treated by BIB balloon dilation and CP covered stent implantation.Results All patients were well recovered,the stent did not appear displaced,folded,aorta dissection and rupture.The pressure difference was 5-10 mm Hg(1 mm Hg=0.133 kPa)between proximal part and distal end after operation.Following up(20±12)months,the therapy efficacy of all the patients was stable and there was no fracture,removal,aortic stenosis or dysarteriotony.Heart ultrasounds demonstrated good close of the cases with patent ductus arteriosus.Conclusion CP covered stent is a safe and available clinical therapy,featured by minimum aorta injuries.

Objective To investigate the expression of Smad5 gene in the cochlea and to identify its location. Methods Reverse transcription polymerase chain reaction (RT-PCR) was employed to detect the expression of Smad5, the in situ hybridization and the immunohistochemical technique were used to localize the Smad5 messenger RNA and the Smad5 protein in mouse cochlea. Results Smad5 gene expressed in cochlea at a high level. Smad5 expression was concentrated in supporting cell, hair cell, spiral ganglion, epithelium of stria vascularis and basilar membrane. Conclusion The Smad5 proteins exist in the mouse cochlea and it may be involved in the cochlear formation and the differentiation of hair cell. Smad5 might be an essential factor for the development of normal cochlea.

Objective To investigate the possible role of leukocytes, a important cellular component of the blood, in the induction of microcirculatory disturbances in noise-exposed cochleae. Methods Guinea pigs were exposed to a 4 kHz narrow band noise at 115 dB SPL for 4 hours, and the exposed cochleae were collected at 2 or 4 days after the noise exposure. Several techniques (cell viability assay, fluorescent labeling for blood plasma and for hair cell nuclei) were used to examine morphological changes in microvessels in the spiral lamina and in the stria vascularis as well as the hair cell nuclei. Results In noise-exposed cochleae, aggregatad leukocytes were found in the vessels of the spiral lamina. In the up-stream of the vessels with aggregated leukocytes, red blood cells were tightly packed, causing an increase in vessel diameters. Most leukocytes were located within the lumen of vessels, but some of them infiltrated the spiral lamina, usually alongside the vessels. Cell viability, assessed by trypan blue staining, showed that these plugged leukocytes lost their viability. In contrast, no leukocytes aggregated in the vessels of the stria vascularis, nor did leukocytes lose their viability. Conclusion In the cochleae exposed to intense noise, leukocytes were trapped in the vessels of the spiral lamina, leading to disturbance of blood flow. The involvement of leukocytes in local damaging processes and the fate of leukocytes need further studies.

To observe the morphological changes in hair cell nuclei in guinea pigs following noise exposure, guinea pigs were exposed to 4 kHz narrow band noise at 115 dB SPL for 4h. The cochleae were collected for the examination of the hair cell nuclei 14 days after the noise exposure. A fluorescent dye, Hoechst 33342,a fluorescent dye, was used to label the nuclear DNA and the specimens were examined under a fluorescence microscope for quantitative assessment of hair cell nuclear damage. There were three types of morphological changes in the damaged hair cell nuclei: nuclear swelling, nuclear condensation (karyopyknosis) and nuclear missing. Nuclear swelling was more frequent than nuclear missing. Nuclear condensation was less frequently found. The results suggested that complicated, long term and non synchronous biological processes might be involved in noise induced hair cell damage. A large number of hair cells with swollen nuclei, which might recover afte wards,still could be seen in the cochlea two weeks after noice exposure.

Objective:To investigate the effect of short term and intensive insulin pump on the blood lipid and glucose levels of patients with type 2 diabetes.Methods:76 patients with type 2 diabetes were selected and divided into two groups according to different administration.The control group (38 cases) was given routine insulin aspart treatment.The observation group (38 cases) was treated by insulin pump.The blood and lipid indexes and ADL score before treatment,at 1 week and 2 weeks after treatment were compared between two groups.Results:After treatment,the levels of FPG,HbAlc,TC,TG and LDL-C were lower than those before treatment and the level of HDL-C was increased in both groups.The levels ofFPG,HbAlc,TC,TG,LDL-C of observation group were lower than those of the control group,and the level of HDL-C of observation group was higher than that of control group (P＜0.05).At 1 week,2 weeks after treatment,the ADL scores of both groups were significantly improved,and the ADL score of observation group was higher than that of the control group (P＜0.05).Conclusion:Short term intensive insulin pump could significantly improve the blood glucose and lipid metabolism disorders in patients with type 2 diabetes,and improve the ability of daily life.

A new, convenient, and rapid method for kinetic measurement of human fibrinolysis was established. The alteration of absorbance (A) in the process of blood coagulation and lyses was automatically scanned and recorded using a UV2000 spectrophotometer connected to a computer. The parameters of human fibrinolysis kinetics were established. Urokinase at 20 U/mL was the optimal concentration used. There was significant difference in fibrinolysis kinetics and plasma plasminogen concentration between 22 normal subjects and 27 patients with acute myeloblastic leukemia (P<0.05 and <0.01 respectively). The coefficience of variation was (5.24+/-1.51)%. This method could also be used to measure the plasma fibrinogen concentration at the same time. It was concluded that this method was stable and was capable of providing dynamic, direct experimental data and multiparemeters for clinicians. It was also valuable in evaluating the anti-and pro-fibrinolytic capcity of patients' plasmas, allowing for monitoring of therapy, choice of drugs and adjustment of drug concentrations.
