Environmental safety technologies of dry cleaning and risk assessment of solvent residue control embody the green consumption's social environmental beneficiary. The safety assurance of dry cleaning with the combination of life cycle analysis and clean production offer dry cleaning industries an efficient way to get rid of health, environmental and social problems from hazardous solvent on the basis of pollution prevention and treatment during production and consumption period.

Objective To study the influence of continous ven ovenuous hemofiltration on patients with multiple organ dysfunction syndrome.Methods 64 patients with MODS were divided into CVVH group(34) and IHD group(30)between 1999-12~2003-12.The serum BUN,Cr,iron,blood pressure,ar rhythmia were monitored during treatment and KT/V was also calculated after each therapy.APACHE-Ⅱ score was assessed before and after the treatment and the pr ognosis of each patient was recorded as well.Results CVVH group had more stable hemodynamics than IHD group; there was no significant difference in the removal of BUN and Cr in the two grou ps.The survival time of CVVH group was longer than IHD,and APACHE-Ⅱ score of C VVH group was lower than that in IHD group,17.23?6.86 verse 20.91?5.77 ( P

Objective In order to discuss the evaluation of generalized sterization for dental handpieces. Methods The generalized sterization for dental handpieces were used inclued collection dental handpieces, automatically cleaned, dried and distilled with oil, packed with paper or plastics and sterized with pulse-vuccum. Results All the indexes were fitted to the standard after the generalized sterization among the dental handpieces. The valid rate was 100%. Conclusions Generalized sterization for dental handpieces are effective measures to guarantee the clinical sterization quality.

Objective To observe the effect and efficacy of DPP-4 inhibitor saxagliptin on nonalcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus.Methods Forty patients with newly diagnosed with type 2 diabetes complicated with NAFLD were divided into two groups:the saxagliptin group and the metformin group.On the basis of dietary and exercise therapies,the saxagliptin group received 0.005 g of saxagliptin daily and the metformin treatment group received 0.85-1.70 g of metformin daily.The levels of glycosylated hemoglobin(HbA1 c),triglyceride (TG),blood pressure (BP),alanine aminotransferase (ALT),liver CT and liver/spleen CT were observed before and 3 months after treatment.Results After treatment for 3 months,the TG,ALT,liver CT and liver / spleen CT of the metformin group and the saxagliptin group were significantly higher than those before treatment(P＜0.05).There was no significant difference in the TG,ALT and liver CT values between the two groups(P＞ 0.05).Conclusion In the state of diabetes mellitus complicate with nonalcoholic fatty liver,saxagliptin has a certain effect on relieving fatty liver.

OBJECTIVE To investigate the clinical degree of satisfaction to sterilizing-supplying center,and to consummate the development of the transition of its decentralized administration to centralized pattern.METHODS We designated the questionnaire of degree of satisfaction(DOS) and carried out the investigation.RESULTS The initiated DOS was 90.6%,the DOS in mid-stage(2006-2007) was 97.3%,and the DOS in the latest stage(2008) was 99.1%.CONCLUSIONS Centralized administration is effective pattern for the development of sterilizing-supplying center and important to ensure the quality of sterile materials and service for clinical medicine.

AIM: The effects of YIGU capsule on proliferation and IGF-I mRNA protein expressions in osteoblasts were studied. METHODS: (1) Forty 12-month old Sprague-Dawley female rats were divided randomly into four groups (YIGU capsule high dose group, medium dose group and low dose group; saline group), the drug-containing serum and control serum were prepared. (2) The new-born Sprague-Dawley rat osteoblasts were cultured with different YIGU capsule drug-containing serum at different concentrations and different exposure time. MTT method was used to observe proliferation of osteoblasts. (3) RT-PCR method was used to measure the relative IGF-I mRNA levels and ELISA method was used to measure IGF-I secretion at different exposure time. (4) ELISA method was used to measure IGF-I secretion at different exposure time. RESULTS: (1) Proliferation of osteoblasts was more than the control groups after 48, 72 and 96 h, respectively (P

AIM: The effects of benefiting-bone Capsule (BBC) containing serum on IL-6 mRNA and protein expression in osteoblasts were studied.METHODS: (1) The neonate Sprague-dawley rat osteoblasts were cultured and divided into three groups: group Ⅰ (containing deactivating serum with BBC), group Ⅱ (containing deactivating serum without BBC) and group Ⅲ (DMEM medium group); (2) RT-PCR was used to measure the relative IL-6 mRNA levels; (3) The radioimmunoassay method was used to examine IL-6 protein in the supernatant of the cultured osteoblasts. RESULTS: (1) The relative IL-6 mRNA levels was lower in group I than the control ( P

OBJECTIVE To reinforce the administration in the management of reusable medical appliances,and to ensure the quality of sterile.METHODS Every step of the integral sterilization were monitored.RESULTS The quality of every link in the course and the end quality of the reusable medical appliances were assured.All the pass-rates of routine examination and sample examination of our hospital and CDC in Zhuhai were 100%.CONCLUSIONS The process of integral sterilization in the management of reusable medical appliances can ensure the quality of sterile materials,and can prevent the nosocomial infections and guarantee the safety of patients.

This article discussed how to separate examination from teaching but at the same time prevent the content of examination being out of joint with teaching when developing the warehouse and review course wares of the examination of emergency medical science,as well as how to make use of a computer to manage the warehouse and review course wares of emergency call medical science examination.

ObjectiveTo investigate the correlation of radial artery and serum osteoprotegerin (OPG) expression and vascular calcification in patients with end stage renal disease.MethodsDiscarded radial arteries were gathered from 43 patients with end stage renal disease(end stage renal disease group)during arterial venous fistula plasty,including 24 patients with no calcification,13 patients with mild to moderate calcification and 6 patients with severe calcification,20 patients with dialysis and 23 patients without dialysis.Discarded arteries from 9 patients with upper limb trauma were chosen as control group.The yon Kossa staining,alizarin red staining and OPG immunohistochemical staining were taken and serum OPG level was measured for all the patients.ResultsSerum OPG level was significantly higher in end stage renal disease group than that in control group [(216.47±83.78) ng/L vs.(57.15±23.22) ng/L,P＜ 0.01 ].Serum OPG level in patients with no calcification,mild to moderate calcification and severe calcification[ ( 152.21±32.21 ),(248.31±53.86),(368.44±53.57) ng/L] and OPG staining value ( 1,2,4 scores) were increased gradually as vascular calcification more serious (P＜ 0.01 ).There was a positive relationship between serum OPG and vascular calcification value(alizarin red staining:r =0.517,P ＜ 0.01 ; yon Kossa staining:r =0.677,P＜ 0.01 ).Serum OPG level and OPG staining value in patients with dialysis were higher than those in patients without dialysis [ (283.57±79.02 ) ng/L vs.( 152.46±30.89 ) ng/L,2 scores vs.1 score,P ＜ 0.01 ].ConclusionsThere is relationship between serum OPG level,OPG expression of radial artery and vascular calcification.
