Objective: To investigate the effects of the cooperative actions of isoflavone, vitamin C and E on the expression of acute C reactive protein (CRP) and interleukin 6 (IL-6) in the patients with typeⅡdiabetic mellitus (DM). Method: Ninety six patients with DM were divided randomly into 4 groups, DM control group(B), and groups receiving low(C), medium (D) , and high (E) dose of the compound antioxidant of isoflavone, vitamin C and E respectively. Another 24 healthy subjects served as normal control group (A). Observe the changes of the levels of CRP and IL-6 during oral glucose tolerance test (OGTT). Results: The peak of serum levels of CRP and IL-6 in the patients of DM control group and lower dosage group appeared 1 h after OGTT and were significantly higher than the 0 h value (P

In this paper, we analyze the status of the medical device testing and the situation of the unqualifie varieties by sorting out the situation of the national medical device supervision and inspection from 2013 to 2016. We analyze the results of the inspection deeply, and find that the safety risk points exists in the quality of the medical device testing products and management system, product technology requirements, the national standards, industry standards or other aspects, then explain one by one with typical examples. At the same time the corresponding suggestions are put forward to production companies and regulators respectively on the existing problems.

Objective To evaluate the feasibility and efficacy of preoperative sequential transcatheter arterial chemoembolization (TACE) followed by selective portal venous embolization (PVE) in patients with marginally resectable hepatocellular carcinoma (HCC).The aim was to find out whether this combined procedure helped to increase the rate of extended radical liver resection.Methods From March 2009 to November 2016,29 patients with HCC which were marginally resectable underwent preoperative TACE combined with PVE were included into this study.All these patients were subsequently assessed to undergo radical hepatectomy.The complications,laboratory results,volume changes of each liver lobe and patient survival were analyzed.Results TACE combined with PVE was successful in all the 29 patients.There were no major complications.After the procedure,the volumes of the tumor and the part of the liver to be resected decreased to certain degree.The remnant liver volume (RLV) increased remarkably.The RLV were (395.4 ±58.7) cm3 and (599.2 ±75.2) cm3 before and after the procedure,respectively.The difference was significant (P < 0.05).19 patients underwent radical hemihepatectomy or trisectionectomy,with a resection rate of 65.5% (19/29).There were sufficient surgical margins in all the resected tumors.After operation,the 1-,3-,and 5-year survival rates were 58.8%,35.5% and 17.6%,respectively.Conclusion For HCC patients who had marginally resectable HCC,preoperative TACE combined with PVE efficiently controlled the growth of the tumors,decreased the volume of the liver lobe with tumor,increased the RLV,and made it possible for a planned two-stage radical hepatectomy with sufficient surgical margin and better survival in a significant proportion of patients.

Objective:To evaluate the performance of aldosterone testing in China through the External Quality Assessment (EQA) and improve the testing quality of aldosterone.Methods:Two kinds of EQA program for aldosterone were carried out in China, one of which is Routine EQA and the other is Trueness verification scheme. Lyophilized sera with 5 concentration levels were used as quality control of Routine EQA. The results were grouped according to the instrument. Target values and the coefficient of variation ( CV) were calculated in each group. Trueness verification scheme was verified by using frozen human sera of 3 concentration levels determined by the reference method, and the bias of each instrument group from the target value was calculated. Results:272 laboratories submitted the testing results, and 91.6% of laboratories used chemiluminescence method. The maximum CV was obtained by radioimmunoassay and liquid chromatography mass spectrometry, and the robust CVs were 14.6%-33.4% and 43.5%-53.9%, respectively. For chemiluminescence methods, the robust group CV was less than 10%. The results of the Trueness verification scheme showed that liquid chromatography mass spectrometry method was the most accurate method, with biases of -7.9%, 8.9% and -0.7% for the three quality controls. Diasorin system had the more accurate results deviated from the target by 58.7%, 7.9% and -2.1%, respectively. The results of other chemiluminescence methods were negatively correlated with the sample concentration, and one of them with a bias of 479%. Conclusions:The accuracy and comparability of aldosterone among laboratories in China are not satisfactory. Reagent manufacturers and laboratories should pay more attention to EQA, with the aldosterone results traceable to SI unit, and improve the test quality of aldosterone.
