Objective To probe into the effect of systematic nursing model on treatment compliance and clinical efficacy of elderly patients with diabetes. Methods 100 elderly patients with diabetes in our hospital were selected from January 2008 to December 2010.The patients were divided into the study group and the control group randomly,50 cases in each group.The patients in the control group were treated with conventional care model,while the patients in the study group were treated with systematic nursing model.The compliance,clinical treatment effect,and improvement of clinical indicators were compared and ana lyzed in two groups respectively. Results Compared with the control group,treatment compliance indexes such as self-monitoring,diet control,medication compliance,exercise therapy in the study group were significantly improved,the difference was statistically significant.Compared with the control group,the clinical efficacy of patients in the study group was significantly improved.Compared with the control group,the FBG,PBG and HbAlc were improved significantly,the difference was statistically significant. Conclusions Systematic nursing model plays a positive role in promoting treatment compliance and clinical effects of elderly patients with diabetes mellitus.The interventions need to be further enriched and perfected.

In order to explore the effects of testicular infection of murine cytomegalovirus (MCMV) on mature sperm viability at different periods following MCMV inoculation in mice, 91 BALB/c mice without MCMV infection were randomly divided into two groups: an experimental group (n = 56) and a control group (n = 35). The mice in the experimental group were treated by inoculating MCMV intratesticularly, while those in the controlled group were directly inoculated with DMEM without MCMV. The mice in both groups were sacrificed separately on the day 1, 1. 5, 2, 4, 6, 9 and 14 post-inoculation (D1) 1. 5, 2, 4, 6, 9 and 14 PI). The MCMV M83 mRNA gene was detected in the testis by in situ hybridization (ISH) with MCMV late-mRNA probe labeled with digoxin. Sperm viability of mature sperm in the epididymis cauda was measured. The results demonstrated the positive signal of ISH of MCMV was found mainly in the cytoplasm of the testicular interstitial cells and spermatogenic cells in the experimental group. Compared with that in the controlled group, the sperm viability in the experimental group was decreased significantly on D1 PI and D1.5 PI (P < 0.05). No statistically significant difference in the sperm viability was found after D2 PI between two groups (P > 0.05). This suggested that sperm viability in mice might be descended significantly shortly after MCMV infection and might return to normal with time, indicating that MCMV acute infection might temporarily degrade sperm quality and influence procreation transiently.

This study was aimed to establish the TLC identification method of Radix Mirab ilis himalaic a. The β-sitosterol and daucosterol were used as the reference substances. The single-factor test was used. A variety of factors which affected TLC were systematically investigated to filter out the best TLC conditions for identification of different batches of medicines. The results showed that the best TLC conditions were as follows: silica gel G plates, extraction solvent (methanol), reagent (5% sulfuric acid in ethanol), extraction method (ultrasonic extraction with methanol), ex-tracted time (30 min), the agent (petroleum ether-ethyl acetate-acetone (5:2:1)) and sample volume (6 μL). It was concluded that the method, which had high separation degree, was reproducible and simple. It can be used as the quality control of Radix Mirab ilis himalaic a.

This study was aimed to apply the electronic nose (E-nose) in the research of traditional Chinese medicine (TCM). The discussion was made on difficulties of using E-nose. The solution plan was proposed and the discrimination model was established. It provided a simple, rapid and effective analysi method in the identification of TCM. It also provided new ideas for the research and application of gas sensor arrays. E-nose was used in the ex-traction of TCM scent characteristics. Based on ion mobility spectrometry of MOS sensor, the fingerprint of TCM scent was established. The maximum response value of the sensor was used as analysis index. According to the diffi-culties of identification, two solution plans were proposed. Firstly, different detectors were employed to complete the classification. Secondly, radial basis function (RBF) and random forests (RF) were combined and then a cascade classifier was constructed in order to achieve the maximum of information obtained in conditions where the number of measurements, metal oxide semiconductor sensors in E-nose was limited. The results showed that both plans were accurate and practical with relatively high upper correct judge rate and better cross-validation (The highest upper correct judge rates were 95% and 100%, 96% and 80%, respectively). It was concluded that this study firstly ap-plied cascade classifier in the establishment of TCM identification by E-nose. With limited amount of sensors, the maximum information was received through data mining. Using E-nose in the identification of TCM was rapid and accurate. The established pattern recognition method was maneuverable with accurate identification rate and stability compared to conventional sensory identification method. It provided a simple and rapid analysis method for the iden-tification of TCM.

Objective To compare differences and similarities of the content of trigonelline in Himalaica mirabilis of either wild or cultivated materials from different places. Methods An HPLC method was established to determine the content of trigonelline in Himalaica mirabilis. ZORBAX XDB-CN column (4.6 mm×250 mm, 5 μm) was used, with mobile phase of acetonitrile-0.03%acetic acid (85∶15), flow rate of 0.8 mL/min, detection wavelength of 265 nm, determination wavelength of 360 nm, and column temperature of 30 ℃. Results Regression calculation was made on peak area with the reference solution concentration, and then got the regression equation A=23.409C-26.398, r=0.999 8. Trigonelline showed good linear relation with peak area among the range of 2.004-200.400 μg/mL. The average recovery of trigonelline was 99.57%, RSD=1.11%. Conclusion There was no significant difference in the content of trigonelline of either wild or cultivated materials from different places. This study laid the foundation of application of the cultivated Himalaica mirabilis.
