OBJECTIVE Employing biological and chemical monitoring methods in steam sterilization qualification tests,to assure the qualification of the steam sterilizers. METHODS BI PCD and B-D test pack for three consecutive testings in empty chamber were used to qualify steam sterilizers. RESULTS Biological and chemical monitoring methods were the most effective monitoring techniques for steam sterility assurance. CONCLUSIONS The qualification tests should be executed exactly with the introduction of steam sterilizer in OR sterile supply division to assure medical safety.

Objective To investigate the predictive values of hypoxia-induced factor(HIF)- 1α and vascular endothelial growth factor (VEGF) in patients with type 2 diabetic kidney disease, and its relationship between HIF-1α, VEGF and glomerular filtration rate (eGFR). Methods Seventy-six patients with type 2 diabetic kidney disease were divided into two groups:DKD1 group [eGFR>90 mL/(min·1.73 m2),n=48] and DKD2 group [60 mL/(min·1.73 m2)0.05). Serum levels of HIF-1α and VEGF were significantly higher in DKD2 group than those of DKD1 group (P<0.05). There were negative correlation between VEGF and HIF-1αlevels with eGFR level (r=-0.59, P<0.01;r=-0.55, P<0.01). ROC curve showed that serum VEGF and HIF-1αlevels were above the opportunity diagonal. The diagnostic sensitivities of HIF-1 to DKD1 and DKD2 were 92.1%and 87.4%. The diagnostic specificities of HIF-1 to DKD1 and DKD2 were 91.7%and 85.4%. The diagnostic sensitivities of VEGF to DKD1 and DKD2 were 96.1%and 86.2%, and specificities were 93.3%and 89.1%. Conclusion Serum levels of VEGF and HIF-1αchange with the severity of diabetic nephropathy are likely to be an early predictor for the progression of diabetic kidney disease.

Xanthelasma palpebrum is the most common type of xanthoma that develops mainly on the inner epicanthus of upper eyelids with symmetrical distribution. The lesion tends to be permanent, progressive and cosmetically disfiguring. The recommended treatment has been surgical excision, local treatment with chemicals, and carbon dioxide laser. All of the mentioned treatment have some disadvantages including scarring, pigmentary change and need for local anesthesia. We describe the treatment of xanthelasma palpebrum with the pulsed dye laser which coagulates the hyperpermeable vessels so that the lipid leakage could be blocked and prevent recurrence and further progression.

Objective_ To investigate the effect of resting heart rate on the progression to diabetes in impaired glucose regulation patients. Methods A total of 638 patients with impaired glucose regulation, from January 2011 to December 2012 in our endocrinology clinic, were selected for the study. According to the resting heart rate, patients were divided into four groups:<66 beat/min group, 66 to 69 beat/min group, 70 to 75 beat/min group, and>75 beat/min groups. All patients'baseline data were collected. The incidences of diabetes in different resting heart rate groups were compared, and the relationship between resting heart rate and the progression to diabetes was estimated using multiple regression analysis. Results In 704 patients with impaired glucose regulation, 636 patients have been completed 2 years follow-up, or reached the end of follow-up ( diagnosed as diabetes ) , the follow-up rate was 90. 34%. During two years follow-up, the incidence of diabetes of<66 beat/min group, 66 to 69 beat/min group, 70 to 75 beat/min group, and>75 beat/min group were 16. 2%, 19. 4%, 25. 0%, and 33. 0%, respectivlely. And the Cochran Armitage trend test showed that χ2 =11. 109, P=0. 001, the difference was statistically significant ( P<0. 05). According to blood glucose monitoring, the 636 patients with impaired glucose regulation were divided into impaired fasting glucose group, impaired glucose tolerance group and impaired fasting glucose combined with impaired glucose tolerance group:the Cochran Armitage trend test showed that, with the resting heart rate accelerating, the incidence of diabetes increased. The incidence of diabetes in impaired fasting glucose combined with impaired glucose tolerance group was higher than that of impaired fasting glucose group and impaired glucose tolerance group ( P=0. 062, 0. 113). The average resting heart rate in 68 impaired glucose regulation patients progressed to diabetes was (79.8±8.3)beat/min,andin568non-diabetescases,itwas(74.5±7.2)beat/min(t=-5.043,P<0.01). With the use of patients progressing to diabetes as the dependent variable, different resting heart rate group as independent variables, and resting heart rate<66 beat/min group as a reference, the logistic regression analysis showed that the risk of the progression to diabetes increased with the resting heart rate levels. Conclusion Higher resting heart rate is linked to higher risk of diabetes in patients with impaired glucose regulation.

purpose: to investigate the adhesive properties of renal tubular epithelial cells on matrigel and compared with the following three cases: ischemia、hypoxia and ischemia & hypoxia(I/H).materials and methods: A micropipette aspiration technique was adopted to determine the adhesive mechanics of renal tubular epithelial cells on matrige. results: it showed that the adhesion of renal tubular epithelial cells on matrigel was higher than that of those three model, further more, a different factor was followed by different adhesive mechanic. conclusion: the adhesion of I/H is lower, the ischemia is higher, but all were lower compared with control. It suggested that effect of hypoxia on adhesive properties of renal tubular epithelial cells on matrigel is bigger than that of ichemia.

Objective To observe the effect of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on cholesterol gallstones formation in C57BL/6 mice with diet-induced cholesterol gallstone,and then explore the potential mechanism.Methods Fifty C57BL/6 mice were randomly divided into 5 groups (10 mice in each group),referring to control group,experimental group,experimental plus DHA group,experimental plus EPA group,as well as experimental plus DHA and EPA group.The mice in control group were fed with regular diet,and the rest of the mice with lithogenic diet (LD).Subsequent to feeding the mice with separate diets for two weeks,EPA and/or DHA (70 mg · kg-1 · d-1) were orally administered for eight weeks,while the LD feeding was continued during this period.After a total of 10 weeks,the mice were dissected to observe the gallstone formation.The levels of serum lipids,total cholesterol (TC) and phospholipids (PL) in bile,and TC in the liver were tested,and the protein expression of HMGCR,SRBI,ABCG5/ABCG8,CYP7A1 and ABCB11genes in the liver of mice was measured.Results Compared with the experimental group,the experimental plus EPA group had significantly lower TC in liver (0.033 ±0.008 mmolo/g) and bile (1.807 ±0.381 mmolo/L),and lower relative protein expression levels of HMGCR (0.545±0.098),ABCG5 (0.418±0.089) and ABCG8 (0.501 ±0.151)in liver (P＜ 0.05).The contents of TC in liver and bile,and the protein expression of HMGCR,ABCG5andABCG8 in liver were 0.048 ± 0.006 mmol/g and 2.662 ± 0.339 mmolo/L,and 1.011 ± 0.213,1.037 ± 0.276 and 1.266 ±0.312,respectively.No significant differences were observed between experimental plus DHA group and experimental group (P ＞ 0.05).Conclusions EPA could prevent the cholesterol gallstone formation in mice by decreasing the expression of HMGCR and ABCG5/8 genes in liver,therefore reducing cholesterol synthesis and blocking cholesterol transport from liver to bile as well as diminishing cholesterol content in the bile.However,the inhibition effect of DHA on cholesterol gallstone formation was not obvious.

Objective To analyze the clonal gene rearrangement and complementarity determining region 3 (CDR3) repertoire of TCR β-chain in fine needle aspiration biopsy (FNAB) specimens of lymph node metastasis in patients with breast cancer. Methods The TCR CDR3 region genes of 24 TCR Vβ subfamilies were amplified by utilizing RT-PCR technology, and the CDR3 lengths of TCR β-chain were analyzed with gene scan technology for 2 cases with lymph node reactive hyperplasia and 3 patients with lymph node metastasis of breast cancer. The clonality of T cells presumed by spectra typing was further confirmed by CDR3 sequencing. Results TCR β-chain presented specific repertoire skewing in metastatic lymph node,and only 3-5 TCR Vβ subfamily of T cells were identified, respectively. Clonal expanded T cells, including oligoclonal, polyclonal patterns, in one or more Vβ subfamilies were found in all cases. The oligoclonal expanded T cells had different CDR3 amino acid sequences. Conclusion There are characteristic T cells cloning proliferation and selected usage of TCR Vβ subfamily T cells could be found in metastatic lymph node.The sequences of CDR3 in different TCR clone proliferation are mostly different.
