Objective To investigate the feasibility,safety and efficacy of sirolimus-eluting stent implanting in diabetic patients with ST-segment elevation myocardial infarction(STEMI)treated by emergency percutaneous coronary intervention(PCI).Methods One hundred and six diabetic patients with STEMI treated by emergency PCI were included into this study.The incidence of major adverse cardiovascular event(MACE),stent thrombosis and restenosis was evaluated.Results Totally 105 patients were successfully treated by emergency PCI and there were no complication during the procedure.Totally 134 sirolimus-eluting stents were successfully implanted on 110 target lesions.There was one subacute stent thrombosis in 106 patients during one month.One-month follow-up result showed that the MACE was 4.72% and the death rate was 3.77%.The MACE was 10.38% and the death rate was 3.77% one year later.One-year angiography follow-up showed that restenosis rate was 11.54%.Conclusion Implanting sirolimus-eluting stent in STEMI patients during emergency PCI is safe and effective.Sirolimus-eluting stent can reduce restenosis rate and MACE in diabetic patients with STEMI treated by emergency PCI.

Objective To evaluate the diagnostic and differential diagnotic values of DSA features for inflammatory pseudotumor of the liver(IPL). Methods An retrospectively comparative analysis of 12 hepatic inflammatory pseudotumors confirmed surgicopathologically from May 2002 to March 2007 with DSA features and correlative imaging data were carried out. Results 10 cases consisted of only 1 lesion and other 2 cases with multiple lesions were opacified initially at the late arterial phase,with prominent peripheral ring-like staining at portovenous and parenchymal phases and less dense opacification in the central region; furthermore heterogenous staining occurred in 5 cases. Conclusions DSA is probable the most appropriate method for the diagnosis and differential diagnosis of hepatic inflammatory pesudotumor.

Objectives: The aim of this study was to define whether growth hormone therapy would reduce the course of postoperative fatigue (POF) in aged patients (60～80 years old) with nutritional support. Methods: Forty aged patients who underwent partial gastrectomy or other operations were randomized into two groups. All patients were treated with the same nutritional support formula.A group of patients was treated with rhGH for 7 day from the third day after operation, and control group treated with placebo.The score of POF, nitrogen balance, transferrin level and body weight were monitored. Results: Score of POF in rhGH group on day 7 and 14 after operation was lower than that in control group(P0.05). Conclusions: Aged patients with rhGH after major operation can recover more rapidly from POF.

Objective This study was designed to describe the localization and the extent of lumbar disc herniations (LDH) by three-dimensional radiological classification and to investigate their potential correlation with symptom and function evaluation.Methods The study retrospectively analyzed 261 patients (284 segments of herniated discs) who were diagnosed with LDH by computerized tomography (CT) or magnetic resonance imaging (MRI) from January 2006 to April 2010.There were 162 males and 99 females,with an average age of 42.1 years old (range,14-67 years) and the mean duration of history is 14.6 months (range,1-38 months).There were 35 cases of heavy manual workers,133 cases of moderate manual workers,and 93 cases of comfortable manual workers.The data were consisted of 188 MRI and 73 CT reports.The three-dimensional radiological classification was applied to describe the localization and the extent of LDH.Oswestry disability index (ODI) scores,Japanese Orthopaedic Association (JOA) scores and visual analogue scores (VAS) were applied to evaluate the vertebral symptom and function.The relationship between three-dimensional radiological classification and their functional status was probed.Results Herniations of lumbar discs located mainly sagittally at Level Ⅰ (151 segments,53.2％) and Level Ⅲ(122 segments,43.0％); horizontally at Area 2 (209 segments,73.6％)and Area 3 (61 segments,21.5％); and frontally at Area b (162 segments,57.0％),Area a (78 segments,27.5％) and Area c (41 segments,14.4％).The ODI scores at visit were 56.91％±13.62％,ranging from 20％ to 90％;JOA scores were ranging from 0 to 24 (mean,13.57±4.68); while VAS scores were ranging from 3 to 10 (mean,6.09±1.89).There was no significant difference on ODI scores,JOA scores and VAS scores between different herniation locations.Conclusion According to the three-dimensional radiological classification,most of the lumbar disc herniations located at Level Ⅰ sagittally,Area 2 horizontally,and Area b frontally.Clinical symptoms and lumbar function did not depend on the location of the lumbar disc herniations by the three-dimensional classification.

Lactose tolerance test with ethanol(LTTE)described by Arola was performed in 41 healthy children and lactose malabsorption(LM)could be diagnosed if blood galactose(B-gal)was less than 0.3 mmol/L or urine galactose less than 2 mmol/L.Then 138 healthy infants and children and 95 children with acute diarrhea were examined for LM or lactose intolerance(LI)with the urine samples of LTTE and symptom-response score(SRS).It was found that LTTE was reliable in the diagnosis of LM ;the incidence of LM or LI increased with the increase of age in children)and RV enteritis was liable to be complicated with LM or Li.

Objectives To compare the co-infection statues of HSV, HBV and HCV in patients with STD and HIV infection for providing evidence of developing prevention and control strategies. Methods Serum samples confirmed to be infected with HIV/AIDS by Western blot, and serum samples of patients with STDs (syphilis, gonorrhoea and chlamydial infection) were tested for HSV2-IgG, HSV2-IgM, HBsAg and HCV-IgG by ELISA. The detection levels were compared between the two groups. Results Out of 76 specimens in STD group, HSV2-IgG was detected in 24 specimens (31.58%), HSV2-IgM in one specimen (1.32%), HBsAg positive in 8 (10.53%), and HCV antibody positive in 4 (1.32%). In 14 specimens of HIV/AIDS group, HSV2-IgG were detected in 7 (50.00%); HSV2-IgM in 5 (35.71%);8 (578.14%) were positive for HBsAg and 3 (21.43%) for HCV. In a total of 90 specimens, both HSV and HBV were detected in 6 specimens, both HSV-IgM and HBV in 2, and the four above-mentioned antibodies in 2. The infection rates of HSV, HBV and HCV were significantly higher in HIV-infected specimens than those in the STD specimens (P

Objective To determine the solubility and apparent oil/ water partition coefficient of sitafloxacin in different solvents. Methods High performance liquid chromatography (HPLC) was used. The column was Dikma Diamonsil C18 (2) (4. 6 mmí250 mm,5 μm). The mobile phase was 0. 05 mol·L-1 KH2 PO4 solution (pH was adjusted with H3 PO4 to 2. 4)-acetonitrile (7030). The column temperature was set at room temperature. The flow rate was 1. 0 mL·min-1 . The detection wavelength was 295 nm and the injection volume was 10 μL. The solubility of sitafloxacin and the apparent oil/ water partition coefficient at pH 2. 0,4. 3,5. 8,6. 6,7. 4,8. 0,10. 0 and 11. 2 were determined. Results The equilibrium solubility of sitafloxacin in water was 0. 44 mg·mL-1 and the apparent oil/ water partition coefficient was 0. 23 (lgP= -0. 64) at (37±2) ℃ . Sitafloxacin has the lowest equilibrium solubility (0. 13 mg·mL-1 ) and the highest apparent oil/ water partition coefficient in pH7. 4 buffer solution system. At pH>10 and pH<5. 8,the solubility of sitafloxacin increased obviously and apparent oil/ water partition coefficient decreased. Conclusion Sitafloxacin is insoluble in water and also poorly soluble in oil,but its solubility could be improved significantly in acidic or alkaline solution.

Objective:To isolate monocytes from human peripheral blood mononuclear cells( PBMC) ,induce macrophages,and identify the function of macrophages.Methods:Monocytes were isolated from PBMC using magnetic activated cell sorting( MACS) anti-CD14 microbead.Sorted CD14+and CD14-cells were checked by flow cytometer to evaluate the efficiency of sorting.The sorted CD14+cells were cultured in IMDM media with 10%human AB serum and 10 ng/ml M-CSF for 7 days to generate macrophages,which were identified by morphological features and phagocytosis function.Results:A high purity of monocytes was obtained by MACS anti-CD14 microbead.The percentage of CD14+cells was 10% and 85.8% before and after sorting, respectively.The macrophages were approximately 40-45 μm in maximum diameter and had the fried egg colony morphological features after 7 days culture.The lymphoma ( Raji) cells were efficiently engulfed by macrophages.Conclusion: The high purity of CD14+monocytes is isolated from PBMC and monocyte-derived macrophages efficiently engulfed lymphoma cells.
