ObjectiveTo observe the effect of acupoints stimulation with silver spike point therapy on insomnia.Methods60 patients with insomnia were randomly divided into the trial group and control group with 30 cases in each group. Patients of the trial group were treated by acupoints stimulation with silver spike point therapy and patients of control group were treated only with Clonopin. All patients of two groups were tested with Self-Rating Scale of Sleep (SRSS) before and after treatment.ResultsThe curative effect rate of the trial group was 86.6%; that of the control group was 60%; the curative effect of the trial group was superior to the control group (P<0.05). SRSS difference of the trial group pre-and post-treatment was 12.79±3.20; that of the control group was 10.1±3.89. There was also a significant difference between two groups (P<0.01).ConclusionThe silver spike point therapy has the better curative effect on insomnia than Clonopin.

The study is to prepare taste masking and enteric-coated clarithromycin granules by melting and fluid bed coating technology. Clarithromycin and matrix materials were melted at a certain temperature, and then made into particles by fluidized bed coating. X-ray powder diffraction and scanning electron microscopy were used to identify the crystal and morphology of drug loading granules. In vitro dissolution method was used for the observation of the drug release behavior. The results showed that the drug particles size range was 0.2 - 0.6 mm; the crystal form of clarithromycin in the granule did not change; enteric-coated granules accumulated release in 0.1 mol L(-1) hydrochloric acid in 2 h was less than 10%, while in pH 6.8 phosphate buffer in 1 h was more than 80%. The taste masking and enteric-coated clarithromycin granules not only have good taste masking effect, but also have a good release behavior. It is expected to have better clinical application.

PEG-modified magnetic Fe3O4 (Fe3O4-PEG) nanoparticles were sythesized using a solvothermal reaction and characterized with transmission electron microscopy (TEM) and thermo gravimetric analysis (TGA). The photothermal effect and photothermal destruction of cancer cells were evaluated. Then the doxorubicin loaded Fe3O4-PEG (DOX-Fe3O4-PEG) nanoparticles were prepared. The cytotoxicity and combined chemotherapy/photothermal therapy (PTT) effect were investigated. Uniform PEG coated Fe3O4 nanoparticles with particle size of 155 nm were obtained in the experiment. The loading and release of doxorubicin on Fe3O4-PEG were pH-dependent. The drug loading capacity in water was 21%. The results of MTT indicated a good biocompatiblity of Fe3O4-PEG nanoparticles and high cytotoxicity of DOX-Fe3O4-PEG. In combined therapy experiment, photothermal therapy demonstrated unambiguously enhanced chemotherapy efficacy. In conclusion, the obtained Fe3O4-PEG nanoparticles which exhibit good photothermal effect and drug loading capacity can be used for chemotherapy and photothermal therapy. The synergetic anti-tumor activity indicates the potential for the combined application of chemotherapy and photothermal therapy in cancer treatment.

Objective To discuss the application effect of peer support education in improving theself-management ability of old patients with diabetes. Methods A total of 160 cases of old patients with type 2 diabetes who were treated and hospitalized from June 2014 to August 2015 were selected, then equally divided into observation group and control group through using random number method.Finally, 76 cases were studiedin observation group, while 75 cases in control group. The health education guidance of conventional diabetes had been used in two groups for six months, and the peer support education was also conducted for the patients in observation group on the basis of conventional education. The self-management ability, insulin standard injection knowledge-belief and attitude-behavior/practice (KAP) and glycosylated hemoglobin (HbA1c) value of old patients with diabetes were observed before intervention, 3 months and 6 months later, respectively. Also,the hypoglycemia frequency in two groups was compared during intervention. Results After three months of intervention, the score of diet, exercise management, glucose monitoring, foot care, pharmaceutical administration and smoke for self-management ability in observation group was 4.63 ± 0.92, 4.18 ± 0.97, 2.86 ± 0.96, 2.35 ± 0.59, 4.01 ± 1.43 and 0.62 ± 0.29, respectively, while that of these indicators in control group was 3.69 ± 0.83, 3.52 ± 0.67, 1.75 ± 0.67, 1.63 ± 0.72, 3.05 ± 1.39 and 0.59 ± 0.38. Except smoke (P > 0.05), the differences between two groups were statistically significant (t=2.987-5.965, P < 0.05). After six months of intervention, the score of diet, exercise management, glucose monitoring, foot care, pharmaceutical administration and smoke for self-management ability in observation group was 5.86±0.93, 5.37±0.61, 3.97±0.94, 5.06±0.92, 5.81±0.73 and 0.89 ± 0.31, respectively, while that of these indicators in control group was 3.68 ± 0.96, 3.65 ± 0.95, 1.86 ± 0.88, 2.65±0.88, 3.21±1.13 and 0.81±0.39. The difference was statistically significant (t=9.336-15.633, P<0.01), except smoke (P>0.05). Then, the insulin was normally injected in observation group after six months of intervention, the score of knowledge, attitude and behavior was 5.63 ± 1.87, 43.17 ± 6.03 and 16.57 ± 1.59, while that in control group was 3.76 ± 0.83, 23.71 ± 0.59 and 10.16 ± 0.95. The differences between two groups were statistically significant (t= 8.569, 15.623, 6.751, P<0.01). Also, the level of glycosylated hemoglobin was decreased from (8.17 ± 0.32) % to (7.16 ± 0.41) %, and the difference was statistically significant (t=-3.560, P=0.000).

Objective Wnt signaling plays an important role in the development and progression of renal cell carcinoma (RCC).This study aimed to evaluate the effects of the Wnt signaling inhibitor 15-oxospiramilactone on the proliferation , migration, cell apoptosis, and cycles of the human RCC cell line 786-0, and to investigate the possible mechanisms of this small molecule acting on RCC in ivtro. Methods We treated 786-0 cells with DMSO ( blank control group ) and 15-oxospiramilactone at the concentrations of1.25μmol/L (low 15 -OSL), 2.5μmol/L (medium 15-OSL), and 5μmol/L (high 15-OSL), respectively, for 72 hours.Then we observed the changes in the proliferation and migration of the 786-0 cells by MTT and scratch-wound assay and determined their apopto-sis and cycles by Annexin V-FITC/PI assay and flow cytometry . Results 15-oxospiramilactone significantly inhibited the growth of the 7860-cells, with the IC 50of 1.088 μmol/L at 72 hours, and decreased their migration distance (P<0.05).After 36 hours of treatment, the apoptosis rates of the 786-0 cells in the low, medium, and high 15-OSL groups were (12.17 ±0.56), (18.54 ± 1.07), and (50.74 ±1.28) %, respectively, significantly increased as compared with (7.85 ±0.42) %in the blank control group (P<0.05), and in an obviously concentration-dependent manner.15-oxospiramilactone remarkably reduced the number of cells in the G0/G1 phase and increased that in the G 2/M phase (P<0.05). Conclusion 15-oxospiramilactone can significantly inhibit the pro -liferation and migration and induce the apoptosis of 786-0cells in vitro.It may be a potential anti-RCC agent.

Objective To analyze the characteristics of preoperative CTO lesions by coronary CT angiography (CCTA) and to compare the lesion characteristics and clinical data of patients with subsequent vs failed PCI.Methods A total of 113 patients were randomly selected and 116 vessels were analyzed by CCTA before PCI.The patients were further investigated as PCI success group vs PCI failure group according to their PCI result.Multivariate logistic regression analysis was used to determine the factors that affected the success of CTO intervention.The ROC curve was used to determine and evaluate the CT-CTO score and J-CTO score for diagnostic efficacy.Results The success rate of PCI was 55.2％.64 lesions were successfully opened,with the success rate of 72.4％.The prevalence of smoking in patients in the PCI failure group was significantly higher than that in PCI success group (65.4％ vs.42.2％,P ＜ 0.05).There were no significant differences between the two groups in age,gender,history of hypertension,diabetes mellitus,and myocardial infarction(P ＞ 0.05).Statistical differences were observed between the PCI success group and the PCI failure group in the presence of occlusion segment head-end bifurcation,occlusion severe incision,severe calcification (calcification ≥ 180°),occlusion segment length ≥ 20 mm,occlusion of calcification lesions,occlusion segment distal shape of the unambiguous of fiber cap shape of the distal occlusion segment under CCTA(P ＜ 0.05).In the PCI failure group,approximately 17.3％ of the patients had previous attempt to open the CTO lesions,which were higher than the PCI success group (9.4％).However,The difference was not statistically significant (P ＞ 0.05).Multivariate logistic regression analysis showed that the unambiguous distal fibrous cap of the occlusion segment and the occlusion of the proximal branch and the occlusion length ≥20 mm were the main factors affecting the failure of CTO intervention.In terms of prediction,the predictive value 30 CT-CTO score yielded a higher area under the ROC curve than that of the J-CTO score (0.8776 vs 0.7387,P ≤ 0.05).Conclusion CT angiography can predict the success rate of intervention for CTO lesions.Compared with J-CTO score,CT-CTO score has a higher predictive value.Unambiguous fiber cap shape,occlusion segment head end bifurcation,occlusion segment length ≥20 mm were the independent risk factors that affecting the success of CTO operation.

OBJECTIVETo explore the expression diversification of CD4(+)CD25(+)CD127(low) regulatory T (Treg) cells and Foxp3 mRNA in the peripheral blood of children with aplastic anemia after the treatment with cyclosporine.

METHODSFifty children with chronic aplastic anemia were enrolled, among whom 30 received cyclosporine treatment (cyclosporine group) and 20 were treated with conventional methods (conventional group). Twenty healthy children were enrolled as the control group. The expression of CD4(+)CD25(+)CD127(low) Treg cells was detected by flow cytometry. The expression of Foxp3 mRNA was detected by real-time Q-PCR.

RESULTSThe expressions of Foxp3 mRNA and CD4(+)CD25(+)CD127(low)Treg cells showed no significant difference between the cyclosporine and the control groups 6 months after treatment. On the contrary, there were significantly lower expressions of both in the conventional group than in the control group (P<0.05). Meanwhile, the cyclosporine group had significantly higher expressions of Foxp3 mRNA and CD4(+)CD25(+)CD127(low) Treg cells than the conventional group (P<0.05).

CONCLUSIONSThe expressions of CD4(+)CD25(+)CD127(low) Treg cells and Foxp3 mRNA in children with aplastic anemia increase after cyclosporine treatment.
