AlM: To investigate the risk factors of diabetic retinopathy ( DR) in type 2 diabetes patients.METHODS:A total of 380 cases of type 2 diabetes were selected from January 2014 to June 2014, divided into DR group (126 cases) and non-diabetic retinopathy ( NDR) as control group (254 cases), all patients were underwent medical history, physical examinations, laboratory and assistance examinations. The prevalence and single factor and multiple factors of DR were analysed by the logistic regression model.RESULTS: The univariate logistic regression analysis showed that DR was associated with diabetes duration, systolic blood pressure, triglyceride, total cholesterol, low - density lipoprotein, urine protein, intraocular pressure, carotid intima - media thickness, peripheral neuropathy disease was the related risk factors for DR. ln multiple logistic regression analysis, only duration was the related risk factors for DR.CONCLUSlON:The occurrence of DR is the outcome of combined action of multiple factors, duration is an independent risk factor for occurrence of DR.

With the rapid development of medical science,‘ faithfulness,expressiveness and elegancy' theory has been endued with novel implications and can guide the translation of medical English.A translation of medical English with high quality should contain faithful information,grammatically complete sentences and understandable words as well as maintain the stylistic features of Chinese abstract,which lead to the speciality and rigour of the article.The guiding role of ‘ faithfulness,expressiveness and elegancy' theory in the understanding and translation of English papers was discussed in this article with common problems selected from medical journals.Several suggestions were proposed to the translators of medical English on the practice of the theory.

Thirty six patients with hypertriglyceridemia and impaired glucose regulation or newly diagnosed type 2 diabetes, whose fasting plasma glucose was ≤8.0 mmol/L, were treated by fenofibrate for 3 months. Lipid profile, insulin during intravenous glucose tolerance test and oral glucose tolerance test ( including glucose) were measured before and after treatment After treatment, lipid profile was significantly improved. Insulinogenic index (△I30/△G30) and acute insulin response were significantly increased (98. 9vs. 129. 2, 3558.9 vs. 4783. 3 pmol · L - 1 · min - 1, respectively, P ＜ 0. 05 ). Fasting insulin and insulin resistant index in homeostasis model assessment ( HOMA IR) decreased ( 128. 6 vs. 84. 8 pmol/L, 4. 8 vs.3.0, respectively, P ＜0. 05 ). The improvement of insulin secretory function was more significant in patients with higher triglyceride (TG ＞ 3. 3 mmol/L). These results indicate that short-term lipid-lowering treatment with fenofibrate can improve β-cell function and insulin resistance. Patients with higher triglyceride are likely to achieve more benefit from lipid-lowering treatment.

Objective To observe the clinical effects by endoscopic implantation of accurate and slow-release particles for advanced esophageal carcinoma. Methods Under endoscopy, we dividing the whole focus into several layers by each 1.0 cm and implanting one slow-release particles (about 10 mg) in each point whose interval is 1.0 cm. One course of treatment includes three-time implantation and each treatment needs four weeks, by the way the details depend on the state of illness. In this research, all of patients complete the treatment smoothly. By comparing the patients’ situation before treatment, three-month treatment and six-month treatment, which include the remission of clinical symptom, the changing of focus area, the improvement of swallow function, untoward effect and life quality, et al. Results The results show several test indexes changed a lot. When treated for 3 months and 6 months, the levels of focus area and swallow difficulty classification were decreased significantly (P < 0.05) as compared with those before treatment; but the patients’ life quality didn’t have significant statistical difference (P > 0.05), by the way there isn’t individual difference appearing because of a little short of testing time and a few of samples. In addition, the WBC had a significant statistical difference between before treatment and three-month treatment (P < 0.05), and the ratio of complication didn’t have a significant change. Conclusions Endoscopic implantation of 5-Fu slow-release particles for the treatment of advanced esophageal carcinoma is a safety, high efficacy, low toxic and good tolerant palliative treatment.

OBJECTIVE: To investigate gene-therapy for human hepatocellular carcinoma with adenovirus vectors by double suicide gene CD/TK. METHODS: Double suicide gene CD/TK was liberated from eukaryotic vectors pCEA-CD/TK and subcloned into shuttle vectors, and the transfer plasmid pAdtrack-CMV-CD/TK was formed after linearizing with Pac 1. It was recombinated with pAdeasy-1 in bacteria BJ5183. The identified adenovirus plasmid was digested by Pac1 and was transfected into 293 cells to pack the adenoviruses. After PCR determination, its titre was measured, and the infection rate and efficacy were tested in human hepatocellular carcinoma cells. RESULTS: pAdtrack-CMV-CD/TK and pAd-CD/TK were tested by endonuclease digestion. Ad-CD/TK was produced in 293 cells, and the human hepatocellular carcinoma cells (SMMC7721) infected by Ad-CD/TK were killed after 5-FC was used, and bystander effects were observed. CONCLUSION: Recombinant adenoviruses with CD/TK fusion suicide gene have a high infection rate and efficacy for human hepatocellular carcinoma cells.

[Objective] The study was conducted to investigate the effect of micronized fenofibrate on acute insulin response in the subjects with impaired glucose metabolism and hypertriglyceridemia. [Methods] Fifty-three subjects were randomly (2:1 ratio) allocated to fenofibrate group (n=36, including IFG 3 cases, IGT 19 cases, IFG/IGT 6 cases, T2DM 8 cases) or control group (n = 17, including IFG 1 case, IGT 9 cases, IFG/IGT 4 cases, T2DM 3 cases) without any intervention for 3 months. Fasting blood samples were collected for measuring fasting plasma glucose (FPG), free fatty acids (FFA), and lipid profile. IVGTTs were carried out with measurement of plasma insulin before and after treatment. Acute insulin response (AIR), the maximum insulin concentrations (C_(INS,MAX)) to fasting insulin (FINS) ratio (C_(INS,MAX)/FINS) and values of the maximum insulin concentrations increment (△C_(INS)) during IVGTT were calculated as indexes of first-phase insulin secretion. HOMA insulin resistance index (HOMA IR) was used for assessing insulin resistance. [Results] After 3-month treatment, the lipid profile was evidently improved in fenofibrate group. Levels of trigiyceridemia (TG), low-density lipoprotein cholesterol and FFA were significantly reduced and high-density lipoprotein cholesterol increased significantly. Waist circumference was also significantly declined. No change of above indicators was found in control group. In fenofibrate group, C_(INS,MAX)/FINS and △C_(INS) were significantly increased (median 8.4 pmol/L vs. 5.3 pmol/L, 808±473 pmol/L vs. 660±472 pmol/L, both P<0.0001), along with great improvement of AIR (5 585±3 441 pmol·L~(-1)·min~(-1) vs. 4 444±3 642 pmol·L~(-1)·min~(-1), P<0.0001). The level of FINS and HOMA IR was also markedly reduced (108±65 pmol/L vs. 166±115 pmol/L, P = 0.002; 3.8±2.3 vs. 6.0±4.2, P = 0.001). In contrast, there were modest declining in acute insulin response (AIR: 4 313～1 943 pmol·L~(-1)·min~(-1) vs. 5 362±2 861 pmol·L~(-1).min~(-1); C_(INS,MAX)/FINS: median 4.6 vs. 7.0, P= 0.01; △C_(INS): 641±286 pmol/L, vs. 720±321 pmol/L, P= 0.003 9) and increasing HOMA IR (7.8±4.2 vs. 5.6±3.2, P<0.000 1) in control group after 3-month follow-up. The improvement of AIR was correlated with the decreasing of plasma FFA and TG (r=0.41, 0.36, P = 0.002, 0.014), but no correlation with the changing of FPG and HOMA IR. [Conclusions] These results indicated that sbort-term lipid-lowering treatment with fenofibrate evidently improved acute insulin response and alleviated insulin resistance in subjects with impaired glucose metabolism and hypertriglyceridemia. Moreover, the improvement of insulin secretion capacity may be mainly due to the relieving of iipotoxity resulting from finofibrate.
