Objective To evaluate the diagnostic value of uroflowmetry of specific bladder capacity in the detection of early diabetic cystopathy (DCP). Methods One hundred and nine patients with type 2 diabetes mellitus (DM) and 48 normal control subjects (control group) were completed the uroflowmetry in bladder capacity about 300 ml. The patients with DM were divided into DM course≥10 years group and DM course<10 years group, glycated hemoglobin (HbA1c)≥7%group and HbA1c<7%group according to the course and HbA1c. The volume leading to first bladder sensation, maximal flow rate (MFR) and average flow rate (AFR) of bladder capacity about 300 ml, and residual urine volume afteremptyingwere measured by uroflowmetry. Results Among the 109 patients with DM, 74 cases (DCP group) had residual urine, and the incidence of DCP was 67.89% (74/109). Thirty-five cases (no-DCP group) had no residual urine. In control group, 8 cases had residual urine. The MFR and AFR in DCP group and no-DCP group were significantly lower than those in control group: (14.44 ± 5.90) and (17.38 ± 5.93) ml/s vs. (23.73 ± 5.81) ml/s, (9.52 ± 4.97) and (10.38 ± 4.46) ml/s vs. (15.88 ± 4.95) ml/s, and the MFR and AFR in DCP group were significantly lower than those in no-DCP group;the residual urine volume in DCP group was significantly higher than that in no-DCP group and control group: 26 (15 - 40) ml vs. 0 and 0 (0 - 51) ml, and there were statistical differences (P<0.05). The MFR and AFR in DM course ≥ 10 years group (27 cases) and DM course < 10 years group (82 cases) were significantly lower than those in control group:(13.34 ± 5.48) and (16.07 ± 6.09) ml/s vs. (23.73 ± 5.81) ml/s, (8.62 ± 3.28) and (10.19 ± 4.96) ml/s vs. (15.88 ± 4.95) ml/s, and the residual urine volume was significantly higher than that in control group:18 (0-75) and 15 (0-30) ml vs. 0 (0-51) ml. The MFR in DM course ≥ 10 years group was significantly lower than that in DM course< 10 years group, and the residual urine volume was significantly higher than that in DM course < 10 years group. There were statistical differences (P<0.05). The MFR and AFR in HbA1c≥7%group (92 cases) and HbA1c<7% group (17 cases) were significantly lower than those in control group: (15.51 ± 5.98) and (15.53 ± 6.60) ml/s vs. (23.73 ± 5.81) ml/s, (9.92 ± 4.74) and (9.88 ± 4.72) ml/s vs. (15.88 ± 4.95) ml/s, and the residual urine volume was significantly higher than that in control group: 17 (0 - 35) and 0 (0 - 24) ml vs. 0 (0 - 51) ml. There were statistical differences (P<0.05). There were no statistical differences between HbA1c ≥ 7% group and HbA1c < 7% group (P>0.05). There were no statistical differences in volume leading to first bladder sensation (P>0.05). Conclusions MFR decrease detected with the technology of uroflowmetry specific bladder capacity may be widely used in screening early DCP.

Objective To examined the relationship between the Fast Plasma Glucose(FPG) and the Postprandial Plasma Glucose(PPG) by analyzing 3 588 OGTT and IRT,and assessed the role of PPG in the diagnosis of type 2 diabetes.Methods Data of OGTT and IRT in 3 588 patients from 2000-Jan to 2007-June were collected and the distribution of the patients evaluated with cut-points of fasting plasma glucose by 5.6 mmol/L,6.1 mmol/L & 7.0 mmol/L and postprandial plasma glucose by 7.8 mmol/L and 11.1mmol/L were analyzed.T-test and corrected t-test of two independent samples have been done with SPSS 11.5.Results By WHO standard,3 097 T2DM were diagnosed.Of 2654 T2DM patients diagnosed by FPG≥7.0 mmol/L,54 patients showed 2 h PG0.05).202 cases were NGT(but hyperinsulinemia and/or delayed insulin secretion were found in 113 of them,55.94%).Other 289 cases were IFG and/or IGT.In the 291 cases diagnozed with 1 h PG≥11.1 mmol/L and 2 h PG

Objective To observe urinary iodine levels in the rat model for excessive iodine intake and monophagia.Methods Wistar rats were randomly divided into 8 groups:normal diet control group(NC),10-fold iodine + normal diet group(10 HI-N),50-fold iodine + normal diet group(50 HI-N),100-fold iodine + normal diet group(100 HI-N),monophagia control group(MC),10-fold iodine + monophagia group(10 HI-M),50-fold iodine + monophagia group(50 HI-M),100-fold iodine + monophagia group(100 HI-M).The excessive iodine intake groups exposed to 1 400,7 600,15 350 ?g/L I-through drinking water presented higher levels of daily iodine intake,which were 10,50,100 times of those in control groups.During the exposure period,the body weights of the rats were measured weekly,the levels of urinary iodine were determined at the second,the fourth and the sixth month.Results The body weights of the excessive iodine intake groups with monophagia were lower than that of the NC group.In normal diet groups and monophagia diet groups,the levels of urinary iodine increased with the increase of iodine intake.The levels of urine iodine in 50 HI-M group and 100 HI-M group were significantly higher than those of the related groups with higher iodine intake.Conclusion The experimental animal model of excessive iodine intake and monophagia are successfully established in the present research,with physical retardation and higher urinary iodine.

Objective To conduct an investigation on diabetes nutrition knowledge, attitude and practice in outpatients with type 2 diabetes, understand the nutritional knowledge and dietary behaviors in patients with type 2 diabetes to guide individualized nutrition education. Methods The diabetes nutrition Knowledge, Attitude and Practice(KAP) questionnairewas designed based onChinese dietary guidelines (2007)andChinese diabetes medical nutrition therapy guidelines (2013). Data of out-patients with type 2 diabetes from January to March 2015 were collected. The method of investigation was face-to-face interview. Results Totally 915 patients were enrolled into this survey(male 495 and female 420). The mean BMI was (27.23 ± 3.18)kg/m2, glycosylated hemoglobin A1c (HBA1c) was (8.03 ± 2.17)%. Among the questions on knowledge, only on 4 questions the rate of awareness was over 80%, and there was a misunderstanding on diet, only 54.10%of diabetes patients believed that diabetes diet should be balanced and reasonable, rather than just limiting staple food and meat. Patients generally could realize the importance of diet for diabetes treatment. For questions on practice, the rate of reaching the standard generally was not over 80%. The rate of correct answers was not significantly different among different age groups, gender, and durations. There was a linear correlation between the rate of correct answers and glycosylated hemoglobin (P=0.043), the correlation coefficient was-0.258. The higher the rate of correct answers, the lower the level of glycosylated hemoglobin. Conclusion Outpatients with type 2 diabetes had good awareness level about diabetic nutritional knowledge and attitude but the awareness level of balanced diet needs to improve, the awareness rate on behavior was relatively low.

Objective To study the abnormalities of noninvasive urodynamios in early diabetes eystopathy (DCP) and provide diagnosis evidences in its early stage. Methods According to the disease course (less or more than 1 year), 85 patients with type 2 diabetes mellitus (T2DM) were divided into new lydiagnosed diabetic group and non-newly diagnosed diabetic group. Thirty healthy cases were involved in normal control group. All of them were checked with the technology of noninvasive urodynamics to measure maximal flow rate, average flow rate, the volume leading to first bladder sensation and residual urine volume. Results As to the 32 newly diagnosed diabetic group, maximal flow rate was (18.4±6.9) ml/s, and average flow rate was (10.6 ± 5.3) ml/s, 18 cases were detected to have bladder residual urine, with the average residual urine volume of (13.2 ± 17.3) ml, and the DCP detection rate was 56.2%(18/32). As to the 53 non-newly diagnosed diabetic group, maximal flow rate was (14.7 ± 6.6) ml/s, and average flow rate was (9.5±4.7) ml/s,38 cases were detected to have bladder residual urine, with the average residual urine volume of (19.3 ± 18.4) ml, and the DCP detection rate was 71.7%(38/53). There was no residual urine detected in normal control group. Their maximal flow rate was (25.7 ± 5.9) ml/s, and average flow rate was (18.0 ± 4.9)ml/s. Compared with that in normal control group, maximal flow rate, average flow rote and residual urine volume decreased in both newly diagnosed diabetic group and non-newly diagnosed diabetic group(P< 0.01). As compared with that in newly diagnosed diabetic group, maximal flow rate in non-newly diagnosed diabetic group decreased obviously (P< 0.05). Conclusions The abnormalities of urodynamics may happen in the early stage of diabetes, and maximal flow rate may be as the most sensitive index. With the new technology of noninvasive urodynamies, we DCP can be diagnosed in early stage and evaluated the function of bladder dynamically.

Objective To carry out the quality control testing and evaluation for three digital mammography systems.Methods The performance of three digital mammography systems was assessed by applying methods recommended in the European guidelines for quality assurance in breast cancer screening and diagnosis and Chinese specification for testing of quality control in X-ray mammography.The performance of X-ray generator of three digital mammography systems were tested and evaluated.CDMAM 3.4 phantom with four different thickness(30,40,50,60 mm) were exposured in DR,PCM,and CR system,respectively.The average glandular dose (AGD) value was measured and image quality figure (IQF) analysis was performed in each thickness.Results The X-ray machine performance of DR and CR was in accordance with existing standard,however the standard was inappropriate to evaluate part of X-ray machine performance of PCM system.The AGDs for system DR were 1.20,1.42,1.75 and 2.20 mGy for 30,40,50 and 60 mm PMMA thickness,respectively.The respective AGDs for system PCM and CR were 0.82,1.19,1.33,1.70 mGy and 0.59,0.88,1.47,2.19 mGy.For the same phantom thickness sequence,the IQFs were 21.36,21.57,27.25 and 30.58 for system DR,28.02,29.10,35.90,and 41.24 for system PCM,whereas they were 39.78,39.30,43.85 and 48.08 for system CR.Conclusions The AGDs of all three systems were in accordance with the values recommended in European guideline.The AGD and IQF could provide an effective way for performance assessment and constancy checks for digital mammography systems.

BACKGROUND: Models concerning tumor external environment mainly concentrated on laboratory two-dimensional culture and in vitro animal experiment, which lack of three-dimensional stereo.OBJECTIVE: To establish in vitro bone metastasis stereo models of human prostate carcinoma, and to investigate the effect of stem cells on proliferation rate and clustering size of prostate carcinoma cells. METHODS: Bone marrow mesenchymal stem cells (BMMSCs) were extracted from 2 clean grade SD rats. Alginate was used to simulate medullary microenvironment, where prostate carcinoma cells and BMMSCs were co-culturedd. Growth of the cells in the three-dimensional model was observed through microscope and histological sections. The carcinoma cells were transfected with green fluorescent protein. The proliferation of monoclonal cells clustering was observed under light microscope and fluorescence microscope. RESULTS AND CONCLUSION: In the co-culture group, the clustering speed, clustering amount and tumor formation rate were greater that those of the control group. The monoclonal cells clustering was formed at 7.75 days and 6.00 days in the control and co-culture groups, respectively, with cell counts of (95.13±11.63) and (112.53±14.67) after 10 days. The formation rate of fluorescent cell clones was (77.10±6.85)% in the control group and (64.55±6.21)% in the co-culture group, the difference had significance. The results suggested that: the alginate microenvironment is conductive to proliferation and clustering of prostate carcinoma cells and BMMSCs.

Objective To evaluate the early detection of diabetic cystopathy(DCP)with the technology of noninvasive urodynamics.Methods 70 patients with type 2 diabetes mellitus(DM)and 30 normal control subjects were checked with the technology of noninvasive urodynamics.Based on their disease course of less or mole than 5 years.the DM patients were divided into two groups.Maximal flow rate,average flow rate,the volume leading to first bladder sensation and residual urine volume were measured by using noninvasive urodynamic technology.Results Among the 70 DM patients,34 were detected to have bladder residual urine,so the DCP detection rate was 48.6%.In the patients with DCP,the average residual urine volume Was 7-139 ml(30.1±27.1)ml,while there was no residual urine in the normal control group.As compared with the normal control group,maximal flow rate and average flow rate were decreased in all the patients with DM and those with DCP(P＜0.01).After follow up of the disease,the patients with a course of more than five years of disease control had even lower maximal flow rate and average flow rate.Conclusion Maximal flow rate decrease and bladder residual urine detected with the technology of noninvasive urodynamics may be widely used in early detection and early diagnosis of DCP.

After treatment for 3 months in the patients with impaired glucose tolerance (IGT), plasma glucose, insulin and homeostasis model assessment for insulin resistance (HOMA-IR) were decreased both in rosiglitazone therapy group and in the group treated with rosiglitazone combined with body weight control.Those parameters in the latter group were decreased more significantly than those in the former.Rosiglitazone ameliorates the insulin resistance in patients with IGT, which is further improved when combined with body weight control.
