Objective To evaluate the effect of consecutive diet nursing intervention on elderly patients with type 2 diabetes. Methods 56 elderly type 2 diebetes patients were randomly selected in control group and were given conventional type 2 diabetes management. The other 56 patients in experimental group were not only given routine care, but also 3 months of consecutive diet nursing intervention. At the 1st and 3rd month, assessment of blood glucose test and quality of life were conducted by all patients conducted. T test, chi-square test were used in the statistics. Results In experimental group, the controlling effect of fasting plasma glucose and 2-hour postprandial blood glucose have been significantly improved. 3 months after the consecutive diet nursing intervention, fasting plasma glucose of control and experimental groups were (7.18±0.89) mmol/L and (6.37±0.74) mmol/L (P=0.027). After 1 months of the consecutive diet nursing intervention, 2-hour postprandial blood glucose of control group and the experimental group were (11.69 ± 1.58) mmol/ L and (9.03 ± 2.13) mmol/ L (P = 0.028) respectively. After 3 months of intervention, the number were were (12.12±2.36) mmol/L and (8.36±1.65) mmol/L respectively (P<0.01). In the experimental group, the therapeutic dimension of quality of life has been gradually decreased and the difference was statistically significant. Conclusions Consecutive diet nursing intervention can effectively improve the blood glucose control of elderly type 2 diabetes patients.

Objective To investigate the necessity to test the hearing of patients whose initial symptom is tinnitus with pure tone audiometer. Methods To analyze the results of pure tone audiometer of 218 tinnitus patients.Results Among 218 cases of tinnitus patients,a total of 123 patients with abnormal hearing,among 95 cases of patients with normal hearing, except for 50 cases of tinnitus, no other cause of disease. Conclusion Among the normal hearing tinnitus patients, we should do further hearing test for them if they are not identified a clear cause of disease,such as auditory brainstem response,otoacoustic emission and other necessary checks to clear the reasons for tinnitus or the position of the unusual auditory system. It is important for early diagnosis and treatment of tinnitus. But the pure-tone audiometer should be a routine examination when tinnitus patients come for the first visit.

Objective To investigate the effects of artesunate (Art) on cell proliferation, apoptosis, nuclear factor (NF)-κB and monocyte chemotactic protein 1 (MCP-1) expressions induced by high glucose in rat renal mesangial cells (HBZY-1), and the mechanism thereof. Methods HBZY-1 cells were cultured and divided into normal glucose group (5.6 mmol/L), high glucose group (25 mmol/L) and high glucose with different concentrations of Art (10 mg/L, 20 mg/L, 30 mg/L) groups. MTT assay was used to detect the cell proliferation after 48 h. The apoptotic rate was evaluated by flow cytometry with Annexin V-FITC/PI double stains. The protein levels of NF-κB and MCP-1 in the cell culture supernatant were determined using ELISA. Results High glucose induced apoptosis and proliferation in HBZY-1 cells, and the expressions of NF-κB and MCP-1 in the supernatant were also increased (P<0.05). After treatment with Art, the proliferation was obviously abolished, and the apoptosis was increased, and the expressions of NF-κB and MCP-1 in the supernatant were decreased in HBZY-1 cells. The effects of Art showed a dose-dependent manner (P<0.05). Conclusion Artesunate treatment can reverse the effect of high glucose in HBZY-1 cells in a dose-dependent manner, which may provide a new therapeutic strategy for diabetic nephropathy.

The pGenesil-1-Beclin1 eukaryotic expression vectors were constructed to establish an SH-SY5Y cell line stably expressing shRNA-Beclin1. The shRNA was connected to pGenesil-1 to construct the recombinant plasmid pGenesil-1-Beclin1, which was transformed into JM109 E. coli. Positive clones were identified by digestion with restriction endonuclease and DNA sequencing. SH-SY5Y cells were cultured by the conventional method. The pGenesil-1-Beclin1 and pGenesil-1 plasmids were transfected into SH-SY5Ycells, and the cells were screened by G418 until the stable G418-resistant monoclonal cells were acquired. Beclin1 mRNA and Beclin1 protein were detected by RT-PCR and Western blot analysis respectively. The results of restriction endonuclease analysis and DNA sequencing confirmed the correct construction of the eukaryotic expression vector pGenesil-1-Beclin1. Two SH-SY5Y transfected cell lines were successfully selected. Compared with the control group, RT-PCR and Western blot showed that the expression of Beclin1 mRNA and protein were down regulated 71.28% ± 1.45% (P < 0.05)and 75.50% ± 2.63% (P < 0.05), respectively. The results indicated that the eukaryotic expression vector pGenesil-1-Beclin1 was successfully constructed and the SH-SYSY cell lines with inhibited Beclin1 expression were established. It provides a useful cell model for studying the biological function of Beclin1.

Conclusion P204 and RAS signal pathway participates in IFN-α regulation of apoptosis of VSMCs in rats.

Objective To investigate the effects of artesunate (Art) on cell apoptosis, tumor necrosis factor-alpha (TNF-α) and interleukin-8 (IL-8) expression induced by high glucose in rat renal tubular epithelial cells (NRK-52E). Methods NRK-52E cells were cultured and divided into normal control group, high glucose group, high glucose with different concen?trations of Art (10 mg/L, 20 mg/L and 30 mg/L) groups, and high glucose with Ena (5 mg/L) group. MTT assay was used to de?tect the cell proliferation. The apoptotic rate was evaluated by flow cytometry with AnnexinV-FITC/PI double stains. The pro?tein levels of TNF-αand IL-8 in the cell culture supernatant were determined using ELISA. Results High glucose inhibit?ed NRK-52E proliferation, induced its apoptosis, and the expressions of TNF-αand IL-8 in the supernatant. Application of Art obviously abolished the effects of high glucose, and the effects of Art were showed in dose-dependent manner. Conclu?sion Art can suppress high glucose-stimulated cell apoptosis, enhance TNF-αand IL-8 expression in NRK-52E cells. The anti-inflammatory action and immune regulation of Art could be a novel approach of treating diabetic nephropathy.
