Objective To observe the therapeutic effect of exenatide combined with metformin therapy in type 2 diabetes with nonalcoholic fatty liver disease.Methods 50 patients with type 2 diabetes and nonalcoholic fatty liver disease were randomly divided into experimental group and control group with 25 cases in each.The control group were treated with metformin, the experimental group were treated with exenatide on the basis of metformin.Before treatment and at the end of 12-week treatment, patients height, weight, body mass index(BMI), waistline(WC), glycated hemoglobin(HbA1c), fasting blood glucose(FBG),fasting C-peptide(FCP), triglyceride(TG), cholesterol(TCH), high density lipoprotein(HDL), low density lipoprotein(LDL),systolic pressure(SBP), diastolic pressure(DBP), alanine aminotransferase(ALT), superoxide dismutase(SOD), liver lipid contents(LFC) were detected.Results Baseline data were not significantly different between the two groups.Compared to baseline, WC, HbA1c, FBG and LFC in experimental group and control group were obviously improved after treatment(P<0.05), and the experimental group improved more significantly than control group(P<0.05).Conclusion Exenatide combined with metformin has an obvious therapeutic effect on BMI, WC, HbA1c, FBG, FCP, SBP, TG, TCH, HDL, LDL, LFC than mere metformin treatment in treatment of type 2 diabetes with nonalcoholic fatty liver disease.

Objective To investigate the morphological changes of bone marrow megakaryocytes in patients with bacterial and fungal infection.Methods Totally 76 patients with microorganism infection from the Second Affiliated Hospital,Zhejiang University School of Medicine from January 2008 to August 2009 were enrolled,including 56 bacteria infected patients and 20 fungal infected patients.All patients received bone marrow examinations,and were positive in microorganism culture.Thirty subjects without infection,hematological disease and other severe diseases were randomly selected as controls.The number and function of megakaryocytes were examined retrospectively, and the size, nuclear lobulation, and vacuolar degeneration of megakaryocytes were quantitative analyzed and compared among the groups.Results The size,nuclear lobulation,vacuolar degeneration,and Yat nuclear of megakaryocytes in bacterial infected group were 2.20 ±0.21,2.11 ±0.23,0.51 ±0.11 and 0.74 ±0.11 respectively,those in fungal infected group were 2.21 ±0.16,2.10 ±0.19,0.52 ±0.10 and 0.79 ±0.10 respectively;while those in control group were 1.40 ±0.10,1.36 ±0.12,0.28 ±0.06 and 0.54 ±0.09 respectively.The differences between bacterial infected group and control were of statistical significance(t values were 14.52,12.19,9.33 and 6.61 respectively,P ＜ 0.05),and the differences between fungal infected group and control were of statistical significance(t values were 16.27,12.34,7.85 and 6.49 respectively,P ＜ 0.05).The size,nuclear lobulation,and vacuoles of megakaryocytes in gram-negative(G-)bacteria group were 2.29 ±0.20,2.22 ±0.26 and 0.57 ±0.10,while those in the gram-positive(G+)bacteria group were 2.13 ±0.20,2.04 ±0.18 and 0.46 ±0.09,and the differences were also significant(t values were 2.07,3.03and 3.56 respectively,P ＜ 0.05).The production of platelet by megakaryocytes in bacterial infected group,in fungal infected and the control were 31.4 ±7.6,32.4 ±6.4 and 41.3 ±5.5,and the differences between bacterial infected group and control,fungal infected group and control were significant(t values were 4.78and 3.98 respectively,P ＜ 0.05).The production of platelet in G-bacteria group was 28.0 ± 6.7,while that in G + bacteria group was 34.4 ± 7.2,and the difference was also of statistical significance(t = 2.41,P ＜0.05). Conclusion Bacterial infected patients have increased megakaryocytes cell body,nuclear lobulation,obvious vacuolar degeneration,Yat nuclear and decreased platelet production function,which are more significant in G- bacteria infected group.

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

Objective To analyze negative lymph nodes of 34 non-small cell lung cancer(NCLC) patients with total correction by means of fluorescent quantitation PCR and immunohistcchemistry,and to form molecular bi- ology staging.Methods Clinical data and tissue samples of 193 lymph nodes were collected from 34 patients under- going resection for non-small cell lung cancer.Using fluorescent quantitation reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry method,lymph nodes were examined for CEA gene mRNA,P53 and CK to form molecular biology staging.All the patients were followed-up for an average of forty months.Results The CEAmRNA was identified in 21.7% (42/193) lymph nodes negative patients from 17 patients(17/34,50%); TMN staging was up-regulated in 8 patients;positive lymph nodes were increased in 9 patients.P53 and AE1/AE3 were identified 9.8%(19/193) from 11 patients,18.6 % (36/193)from 15 patients,separately;TMN staging was up-regulated in 2 patients of P53 examination and 5 patients of AE1/AE3 analysis;positive lymph nodes were in- creased in in 7 patients of P53 examination and 11 patients of AE1/AE3 analysis.There was obvious statistical sig- nificance in them,but the molecular biology staging based on the three markers was not an independent factor on re- currence and metasis of lung cancer.Conclusion CEAmRNA.P53 and AE1/AE3 analysis could find lung cancer micrometasis more sensitively to form molecular biology staging which was relative to the prognosis,but not an inde- pendent prognostic indicator.It might be good to the therapy strategy after operation.

Objective To learn the prevalence and trends of Brucella disease in Ningxia, in order to provide scientific basis for effective control of the disease. Methods Data of Brucella cases reported through city network from 2004 to 2009 in Yinchuan city, Shizuishan city, Wuzhong city, Guyuan city and Zhongwei city of Ningxia were reviewed and retrospectively analyzed. The data included demographic characteristics, treatment conditions and medical history so on related information. Analytical indicators include reported incidence;with patients' gender, age, regional distribution, urban and rural distribution;become chronic and associated factors;distribution of the cases reporting unit and so on. Results From 2004 to 2009, Ningxia had reported 349 cases of Brucellosis, no deaths, the annual incidence rates reported were 0.017/10 million, 0.543/10 million, 0.151/101 (295/54);The proportion of 34- to 40-year-old age group was higher than other age groups(27.5%, 96/349);Occupational distribution of patients was mainly farmers and herdsmen(70.2% ,245/349), in regional distribution of the patients, the highest percentage was Wuzhong city(61.9%,216/349), followed by Yinchuan city(22.9%,80/349);The proportion of patients in rural areas(97.4% ,340/349) was higher than urban(2.6% ,9/349);the proportion of patients converted to chronic was 11.2% (39/349). With age, the chance of patients converted to chronic was in a decreasing trend(odds ratio was 0.966);cases reported by Centre for Disease Control and Prevention accounted for 74.8%(261/349), by hospital accounted for 25.2%(88/349). Conclusions The reported incidence of Brucellosis in Ningxia is in a rapid upward trend year by year, the patients is mainly young men, the rate of converted to chronic is higher and the ability of hospital in founding and reporting of the cases is weaker.Comprehensive measures should be taken to increase funding, strengthen monitoring, and continuously improve the level of awareness and diagnosis of medical personnel for further strengthen the prevention and control of Brucellosis.

Objective To learn the plague's host animals and parasitic flea composition, and to investigate the natural foci of plague in Xiji county in order to provide basic information for plague prevention and control. Methods The Citellus alaschanicus density, nocturnal rodents, the body flea, the burrow track flea, the nest flea were investigated in 8 townships (town) of Xiji county from June 11 2007 to July 25 2007. Specimens of small mammalian, fleas were collected for bacteriological and serological testing. Results The average density of the main host Citellus alaschanicus was 0.85 per hectare. The nocturnal mouse capture rate was 0.80%(24/2987).The survey found 16 species of small mammals that belonging to 3 orders, 9 families and 16 species with Citellus alaschanicus the dominant species. The Citellus alaschanicus had 2.84 fleas per body. Four families and 16 species of fleas were identified in the areas. The Citellus alaschanicus and Citellophilus Tesquorum Mongolicus were the dominant species. Plague bacteriology and serology tests were negative.
