Objective:To investigate the efficacy and safety of metformin in the treatment of elderly patients with diabetes. Meth-ods:Totally 72 cases of elderly patients with diabetes in our hospital from January 2012 to December 2012 were randomly divided into the observation group and the control group. The observation group was received metformin, and the control group was given repaglin-ide. The efficacy and safety of the two groups were compared. Results:After the treatment, blood sugar of fasting, 2h after meals and 10:00 p. m. in the observation group and the control group was significantly decreased (P<0. 05), and blood sugar of fasting in the observation group was significantly lower than that in the control (P<0. 05), while that of the other time points was without significant difference (P>0. 05). The HbA1c levels before and after the treatment in the observation group was with statistically significant differ-ence (P<0. 05), and those in the control group was without significant difference (P>0. 05). The incidence of adverse reactions in the observation group was lower than that in the control group(P<0. 05). Conclusion:Effect of metformin in the treatment of elderly patients with diabetes is remarkable and safe, which is worthy of further promotion and application.

Objective To analyze the change of the shear stress in atherosclerotic carotid artery of rabbits and its effect on the plaque and intimia-media pathological morphology. Methods Totally 36 male Japanese White rabbits were randomly divided into blank control group (n=6), sham operation control group (n=6) and the surgery group (n=24). The blank control group was fed by normal diet. The sham operation control group was fed by the high-cholesterol diet. The surgery group was fed by high-cholesterol diet and treated by air-drying. In the 2nd, 4th, 8th and 12th week after operation, the hemodynamic parameters were measured using Color Doppler Flow Imaging. Blood viscosity was determined and the degree of artery stenosis was showed by digital subtraction angiography (DSA). The stenosis rate, mean shear stress, intimia-media ratio and mean integrated optical densities (IOD) of media smooth muscle cells (SMC) were calculated respectively. Results The typical atherosclerotic plaque was presented in surgery group. The thickness of media and mean IOD of SMC were increased at the 2nd week after operation. However, following the increase of the stenosis rate and shear stress, the flow field was changed on the stenotic artery. The pathological morphology showed the character of vulnerable plaque such a large lipid core, thin fibrous cap, and plaque rupture at 4th, 8th week after operation. The media showed atrophy and became thin, mean IOD of SMC was decreased. Statistic analysis showed significant difference in the 2 week group compared with other group. Conclusion Following the increase in the degree of stenosis, the flow shear stress is increased, turbulent flow presents, and flow field changes on the stenotic artery. Thus the plaque become unstable , and the vessel occurs remodeling.

The quality of pharmaceutical care can be enhanced and the incidence of disputes can be reduced or evaded through institutionalized management, standardized operation and humane concern showed to patients etc.

Objective To explore how to apply SWOT analysis method for analysis in nursing management in special wards,to develop individualized measures,and to evaluate the clinical quality of care. Methods Using SWOT analysis method to investigate the internal strengths factors,internal weaknesses factors,external opportunities factors,and external threats factors and arranged as a matrix in accordance with a certain order,and used systems analysis methods to analyze the factors matching each other,to dr aw the appropriate conclusions,and to develop appropriate countermeasures.30 patients before and 40 patients after the application of SWOT analysis method were selected for effect comparison. Results After the implementation of SWOT analysis method primary care,I-level care,health education quality,satisfaction degree of patients and ward management score were better than those before the implementation. Conclusions SWOT analysis method was intuitive and simple to use.It possesses balance and systematieness,which is suitable for clinical care management.

Objective To evaluate the systolic function of left ventricle in myocardial infarction(MI)patients with ventricular aneurysm and the changing law of blood flow in ventricle with regional abnormality of wall movement by vector flow mapping (VFM).Methods Tirty-one MI patients with ventricular aneurysm and 35 healthy participants were enrolled in this study.The characteristic of vector and streamline,and the changing of the velocity gradient in left ventricular outflow tract (LVOT), and the average flow quantity through aneurysm neck were detected in the isovolumic contraction period, the rapid ejection period and the slow ejection period by VFM.Results The distinction between aneurysm and control group was mainly the persistance of vortex in aneurysm.The size of vortex in aneurysm was highly correlated with that measured by 2-D ultrasound(P ＜0.01).The percentage of vortex duration to cardiac cycle in patients group was significantly greater than that in control group(P ＜0.01).In the early systolic contraction the velocity gradient in LVOT in patients with ventricular aneurysm was smaller than that of control group(P ＜0.05).The average flow through aneurysm neck was notablely decreased compared with control group(P ＜0.01).Conclusions VFM can reveal the hemodynamics of left ventricle with aneurysm directly as well as quantitively measure the regional velocity and flow quantity.VFM can evaluate the systolic function of left ventricle exactly.

Objective:To discuss the effect of amlodipine combined with atorvastatin in the treatment of elderly patients with acute cerebral infarction hypertension. Methods:Totally 86 cases with acute cerebral infarction hypertension were randomly divided into the treatment group (43 cases) and the control group (43 cases). The control group received amlodipine 5mg, po, qd, and the treatment group was given atorvastatin 20mg additionally, po, qd. After the one-month treatment, the efficacy of the two groups was studied and compared, and the changes in neural function defect scale, blood pressure, blood lipids and CRP were also investigated. Results:Af-ter the treatment, the total effective rate and the total effective rate of antihypertensive effect in the treatment group were both signifi-cantly higher than those in the control group (P<0. 05). The neurological deficit scores of the two groups were significantly higher than those before the treatment (P<0. 05), and those of the observation group was significantly higher than those of the control group (P<0. 05). The blood pressure of the two groups was both decreased after the treatment(P<0. 05), and the decrease in the treat-ment group was more significant (P<0. 05). TC, TG, LDL-C and CRP levels of the two groups had significant decrease after the treatment (P>0. 05), and those in the treatment group was significant lower than those in the control group (P<0. 05). Conclu-sion:Amlodipine combined atorvastatin in the treatment of elderly patients with acute cerebral infarction hypertension shows significant effect with low incidence of adverse drug reaction, which is worthy of wider application.

Breast cancer and thyroid diseases are common diseases in women.It is reported that breast cancer and thyroid diseases have some relevance.Breast cancer patients have relatively high incidence of thyroid dysfunction,thyroid node and thyroid cancer,which are easily misdiagnosed for lacking of obvious clinical manifestations and will affect the treatment and prognosis of breast cancer.In breast cancer patients,screening and diagnosis of thyroid function and disease through thyroid function detection and ultrasound examination should be strengthened.

AIM: To investigate the mutagenicity of cadmium and zinc and the effect of zinc on the mutagenicity of cadmium. METHODS: The frequency of sister chromatid exchange (SCE) induced by cadmium, zinc and the combination of cadmium and zinc were observed in cultured human lymphocytes. RESULTS: Cadmium induced the increase in frequency of SCE in human lymphocytes from the concentration 1?10~(-8) mol/L to 1?10~(-6) mol/L, but zinc had a negative result. Zinc reduced the frequency of SCE induced by cadmium at the concentration from 1?10~(-6) mol/L to 1?10~(-4) mol/L and a relationship between dose and effect was also observed. CONCLUSION: Zinc inhibits the mutagenicity of cadmium in cultured human lymphocytes.
