OBJECTIVE:To discuss the effects of different intensive treatment on B islet cell function in patients with newly diagnosed type 2 diabetes. METHODS: 54 patients who had been newly diagnosed as having type 2 diabetes were randomly assigned to receive Insulin aspart 30 or Glimepiride combined with Metformin (oral hypoglycemic agent). The blood glucose, glycosylated hemoglobin (HbA1c), and B islet cell function in two groups before and after treatment were followed. RESULTS: After treatment, blood glucose and glycosylated hemoglobin (HbA1c) in both group lowered significantly (P

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 examine the advanced oxidation protein products (AOPP) in patients with acute coronary syndrome(ACS) and discuss the relationship between oxidative stress with the development of atherosclero-sis(AS). Methods Plasma were collected in 59 acute myocardial infarction (AMI) patients including 35 patients underwent selective PCI,24 patients underwent emergency PCI,43 unstable angina pectoris(UA) patients and 10 non-coronary artery disease (non-CAD) patients. All cases underwent coronary angiography (CAG). Plasma was collected immediately,post-24 hours and post-48 hours after admission. AOPP was determined by measurements of absorbance (A) at 340 nm under acidic conditions via spectrophotometry. Results AOPP was (236.42±30.41) ( n = 35 ), ( 207.84±29.50 ) mmol/L ( n = 35 ), ( 227.79 ± 35.18 ) mmol/L ( n = 31 ) respectively immediately, post-24 hours and post-48 hours after admission in AMI ( selective PCI ), ( 239.95 ±39.94 ) mmol/L ( n = 43 ), (175.92 ±29.46) mmol/L(n =38) ,and (156.54 ±28.29) mmol/L(n =35) in UA group and (57.41 ± 13.60) mmol/L( n = 9 ), (56.11 + 11.90) mmol/L ( n = 10 ) and ( 61.75 ± 12.28 ) mmol/L ( n = 8 ) in non-CAD group. Compared with normal group ( without CAD ) , significantly higher plasma AOPP was detected in AMI ( selective PCI) and UA patients ( P < 0.05 ). AOPP level was significantly increased in AMI selective PCI patients as compared with that of emergency PCI group immediately and post-24 hours after admission( P <0.01 ) ,and post-48 hours after admission( P < 0.05 ), but there was no statistical significance between emergency PCI and UA group( P > 0.05 ). Conclusions Oxidative stress is an important step in the development of atherosclerosis, and the higher levels of AOPP in ACS patients show that AOPP may be as good markers in these patients.

Objective To explore the value of interphase fluorescence in situ hybridization(FISH) in the detection of trisomy 8 in patients with hematologic disorders. Methods Seventy-seven patients were vestigated by directly labeled centrome DNA probes specific for 8 chromosome. The results were compared with that of conventional cytogenetic (CC) analysis. Results The proportion of trisomy 8 of 77 cases of hematologic disorders detected by FISH is higher than by G-banding karyotyping and FISH could offer the result when conventional cytogenetic methods failed to diagnose. Conclusion Interphase FISH is more sensitive in the detection of trisomy 8 than CC, and FISH displays its superiority in the detection of small clone.

Objective To survey the cognitive attitude and participation intention for stakeholders of public hospitals,in order to provide basis for public hospitals social evaluation.Methods 621 stakeholders of public hospitals were subject to the questionnaire survey.Results 76.7%(475/619) stakeholders held it as necessary to independently launch the public hospitals social evaluation,and held that the evaluation subjects selection should be professional(83.8%),independent(67.7%),authoritative (55.6%),and proactive(46.1%).The survey also recommended that social evaluation of public hospitals should have such indexes as government investment (80.2%),social supervision (76.0%),and information disclosure system(7 1.1%).The overall willingness rate of stakeholders to participate in the public hospital social evaluation was 7 1.6%.Conclusions Development of the social evaluation index system of public hospitals and diversified evaluation subj ects are key to developing the theory and practice system of public hospitals social evaluation.

Objective To analyze the setup errors of external?beam and intracavitary radiotherapy for cervical cancer based on the data of cone?beam computed tomography ( CBCT) , and to provide a basis for clinical practice. Methods Sixty patients with stage ⅡA?ⅢB cervical cancer who were admitted to our hospital and underwent external?beam and intracavitary radiotherapy from March to June, 2015 were enrolled as subjects. Sixty patients with stage ⅡA?ⅢB cervical cancer undergoing conventional external?beam radiotherapy within the same period were also enrolled. The CBCT?based setup errors, containing setup errors in x, y, and z directions and three?dimensional vector deviation, in the initial treatment were obtained from each patient. Comparison of errors between the two treatment approaches was made by independent?samples t test. Results Fitting the data to a linear model revealed that the setup errors in x, y, and z directions increased with the increase in the distance between the position reference point and the center point of the target volume. External?beam radiation combined with intracavitary radiation had significantly reduced setup errors in x, y, and z directions than the conventional external?beam radiation ( 0.13± 0?12 vs. 0.31± 0?24, P=0?000;0.23±0?18 vs. 0.47±0?36, P=0?001;0.18±0?11 vs. 0.27±0?18, P=0?001). Conclusions In order to reduce the setup errors, CT scan needs not only a reference marker as close as possible to the center of the tumor, but also a reliable and accurate approach for postural fixation.

Objective To establish the gas chromatographic(GC) fingerprint of oleic acid of Whitmania pigra Whitman for its quality control. Methods Ten batches of Whitmania pigra from different sources and processed by different methods were analyzed with Agilent 6890N gas chromatography detector on DB-WAX(30 mm × 0.32 mm × 0.25μm)column at the vaporizing temperature of 270℃, column temperature of 130℃and flame ionization detector (FID) temperature of 280℃. We used a software of Similarity Evaluation System for Chromatographic Fingerprint of TCM(Version of 2004A) published by Chinese Pharmacopoeia Commission to calculate GC similarity. Results Oleic acid content of Whitmania pigra processed by different methods had significant differences (F2,7 = 7.350, P = 0.019). The oleic acid content of samples dried after washing with clean water significantly differed from that of the samples processed by alumen or the slices dried naturally(P = 0.021, P= 0.009). The similarity of the fingerprints was in the range of 0.458 - 0.998. The similarity of samples from Lipu of Guangxi Province was the lowest. Conclusion The fingerprints of most of the samples have very high similarity. The established GC fingerprints can be used to effectively identify the qualified or inferior Whitmania pigra products, which will provide some reference for the quality control of Whitmania pigra.

Objective: To analyze the effects of Clostridium difficile toxin B (TcdB) on the proliferation and apoptosis of colon cancer cell line SW480 and the possible mechanisms related to cell apoptosis. Methods: SW480 cells were treated with different concentrations of TcdB. Cell proliferation was detected by MTT assay. Cell apoptosis and mitochondrial membrane potential were measured with flow cytometry. Results: TcdB significantly inhibited the proliferation of SW480 cells in a time-concentration dependent manner and the inhibition rate reached 46.36% at 48 h. Flow cytometry results showed that TcdB could induce the apoptosis of SW480 cells in a time-concentration dependent manner and a 20.83% apoptosis rate was induced by 800 ng/ml of TcdB at 48 h. Conclusions TcdB could inhibit the proliferation and induce the apoptosis of colon cancer SW480 cells, and the possible mechanisms might be relate to the initiation of mitochondrial apoptosis pathway.

Objective:To investigate the detection of suspected occupational diseases in the occupational health examination population in Hangzhou, and to establish a two-level logistic model of influencing factors.Methods:In October 2018, the information of physical examinees was collected through the 2015-2017 occupational health examination and reexamination database of Hangzhou Hospital for the Prevention and Treatment of Occupational Disease. MlwiN 2.02 software was used to establish a 2-level logistic model of suspected occupational diseases, with the occupational hazard factors as the level 2 unit and the employees as the level 1 unit. χ 2 test was used to compare the detection rates of suspected occupational diseases with different characteristics. The trend of detection rates of suspected occupational diseases with age and working age were tested by Cochran-Armitage trend test. Results:The morbidity rate of suspected occupational diseases in 2965 workers was 59.6% (1767/2965) , and the rates caused by different occupational hazardous factors were significantly difference (χ 2=1615.27, P<0.01) , that caused by noises was the highest (98.0%, 1206/1231) , and the next was the dust (87.5%, 70/80) . The rate in male was 61.5% (1532/2492) , and that in female was 49.7% (235/473) , they were significantly difference (χ 2=22.96, P<0.01) . The rates of suspected occupational diseases increased with the ages ( Z=8.77, P<0.01) and working years ( Z=3.62, P<0.01) . The multivariate analysis by 2-level logistic model indicated that gender, age and working year were all no significant, instead the level 2 unit random effect was significant (χ 2=4.77, P<0.05) . Conclusion:Suspected occupational diseases will occur in clusters in occupational hazardous factors. The influence of occupational hazardous factors on suspected occupational diseases was more than that of personal characteristics.
