Objective To explore the value of the combined detection of four tumor markers of serum CA125,CA153,CA199 and CEA in the diagnosis of epithelial ovarian carcinoma(EOC).Methods The serum levels of CA125,CA153,CA199 and CEA were detected before operation in 54 cases of ovarian cancer and 68 cases of ovarial benign lesion and 55 healthy women as the con-trol group,by using chemiluminescent immunoassay(CLIA).The statistical software SPSS 13.0 and MedCalc 10.4.0.0 were used to retrospectively analyze the results.Results The sensitivity,specificity and accuracy of the single index detection and the com-bined detection were calculated.The sensitivity,specificity and accuracy of CA125 were 96.3%,64.7% and 78.7% respectively, which were higher than other single index′s.In the combine detection,the sensitivity and accuracy of the combined detection of CA125 and CA153 were 99.1% and 79.5% respectively,which were higher than those in the optimal single index CA125 and the other combined detection(P <0.05).Conclusion The combined detection of CA125 and CA153 is superior to the CA125 single in-dex detection in the diagnostic value for EOC.

Differential diagnosis of benign and malignant ascites is of a great value in determining etiology, evaluating prognosis, and determining therapy regimens. There are many diagnostic methods for ascites, but up to now, no method can achieve high sensitivity and specificity and meet the requirements of clinical economics and feasibility at the same time. Therefore, searching for an ideal method for differential diagnosis of ascites has become an important topic of current research. This article describes the clinical value of diagnostic methods, such as molecular biological detection, cytological examination, combined determination of tumor markers, and routine tests, in the differential diagnosis of benign and malignant ascites, analyzes the diagnostic efficiency of related biomarkers, and points out that combined determination of various parameters has an increased value in the differential diagnosis of benign and malignant ascites.

OBJECTIVE To investigate the effect of norepinephrine (NE) on expression of interleu?kin-6 (IL-6) in human macrophages and explore its pro-inflammatory and pro-atherosclerotic mecha?nisms. METHODS Murine U937 macrophages were cultured and stimulated with 0.01-10μmol·L-1 of NE for 6, 9, 12, 24 and 48 h. The IL-6 mRNA level of 24 h was analyzed by RT-PCR, and IL-6 protein expression in the supernatant at 0, 6, 9, 12, 24 and 48 h was detected by ELISA. After 24 h, intracellular reactive oxygen species (ROS) generation was observed by DCF fluorescence. The cells were pretreated with antioxidant N-acetylcysteine (NAC), complexⅡinhibitor thenoyltrifluoroacetone (TIFA) and NADPH oxidase inhibitor diphenyleneiodonium (DPI) for 1 h, and stimulated with different concentrations of NE for 24 h, before the level of IL-6 protein was detected by ELISA. RESULTS The expression of IL-6 mRNA and protein increased with the concentration NE 0.01-10 μmol · L-1 and incubation time. IL-6 mRNA and protein levels in macrophages were 2.62 and 4.47-fold those in cell control group when treated with NE 1.0μmol·L-1 for 24 h. Meanwhile, as the concentration of NE increased, the generation of ROS was 1.87, 2.56, 2.91 and 5.36-fold that of cell control group (P<0.01). NAC 10 mmol · L-1 and DPI 10 μmol · L-1 significantly antagonized the effect of NE on IL-6 expression, but TIFA had no effect. CONCLUSION NE upregulates IL-6 expression, which may contribute to the formation and develop?ment of atherosclerosis via ROS mediated by NADPH oxidase in macrophages.

Objective To investigate the effects of short-term continuous subcutaneous insulin infusion (CSII) in newly diag-nosed type 2 diabetes mellitus(T2DM ) and to evaluate the treatment regimen conversion after CSII therapy .Methods 72 patients with newly diagnosed T2DM were treated with CSII for 2 weeks .Then they were randomly divided into two groups :the basal insu-lin group(glargine) and the oral anti-diabetic drug(OAD) group .Both groups were followed up for 2 years .Blood glucose ,insulin and HbA1c were measured before and after CSII and during the 2-year follow-up .Results CSII significantly controlled the glucose levels ,reduced the TG ,TC ,LDL levels and the homeostasis model assessment of insulin resistance ( HOMA-IR) and increased the homeostasis model assessment of insulin secretion (HOMA-IS)(all P< 0 .05) .During 1-year follow-up ,HbA1c in the glargine group and the OAD group was (6 .13 ± 0 .47)% and(6 .21 ± 0 .38)% respectively .During 2-year follow-up ,the HbA1c values in the two groups were (6 .91 ± 0 .57)% and(6 .43 ± 0 .62)% respectively .T HOMA-IR and HOAM-IS obtained the long tern improve-ment without significant body weight increase .Conclusion Short-term intensive insulin therapy can effectively control the blood glucose ,improve the sensitivity of insulin and the β-cell function ;after CSII ,adopting basic insulin and oral antidiabetic drugs can a-chieve the ideal glycemic control .

AIM:To compare the clinical efficacy of three combined surgical treatments for cataract induced by silicone oil -filled eye.
METHODS: The data of 75 eyes of 75 patients with cataract induced by silicone oil-filled eye were reviewed. Those patients were divided into group A, B, C. The patients in group A were treated by phacoemulsification combined with silicone oil removal through pupil and IOL implantation, the patients in group B were treated by phacoemulsification combined with silicone oil removal through 23G vitrectomy system and IOL implantation, the patients in group C were treated by phacoemulsification combined with silicone oil removal through 20G vitrectomy system and IOL implantation. The operation time, intraocular pressure, best corrected visual acuity ( BCVA ) , discomfort days and complications before and after the surgery were compared.
RESULTS: The differences of the intraocular pressure were not statistically significant between the three groups after the surgery. The BCVA of the three groups were all improved, but the differences were not statistically significant between three groups. The differences in postoperative complications showed no statistically significant. Otherwise, group A and B cost less operation time. The discomfort days of group A were less than other groups.
CONCLUSION: Three different surgical methods were safe and effective, appropriate surgical approach could be chosen according to the patients' clinical manifestations. For patients with cataract induced by silicone oil-filled eye whose retina recovered well, phacoemulsification combined with silicone oil removal through pupil and IOL implantation is a time-saving, safe and effective method.
