Objective To explore the effects of exercise nursing intervention on renal transplant recipients.Methods A convenient sample of 64 renal transplant recipients during rehabilitation period were divided into the experimental group and the control group with 32 cases in each group.The experimental group received routine care and rehabilitation exercise,while the control group just received routine care.The body mass index(BMI),blood pressure and heart rate were measured in the two groups.Results Before intervention the differences of BMI,heart rate,blood pressure between the two groups were not statistically significant.However,after intervention,the BMI and blood pressure of the experimental group were lower than those of the control group,but there was no significant differences in heart rate.Conclusions Rehabilitation exercise nursing intervention contributes to raise recipients' quality of life and promote whole rehabilitation.

BACKGROUND:Extensive research has been concentrated on the reconstruction of periodontium under orthodontic force. However, there are no reports regarding the expression of heat shock protein 70 (HSP70) in rat periodontium during orthodontic tooth movement. OBJECTIVE:To investigate the expression of HSP70 in rat periodontium during orthodontic tooth movement. METHODS:Rat orthodontic tooth movement models were established using NiTi extension spring with the force of 50 g. The orthodontic periodontium was col ected at 1, 3, 5, 7, 10 and 14 days after exerting force to detect the expression of HSP70. RESULTS AND CONCLUSION:According to immunofluorescence staining, the expression of HSP70 in the periodontal tissues was increased on day 1 after exerting force, and reached the highest level on day 5, then decreased to the initial level on day 14. These results suggest that the expression of HSP70 is evoked by orthodontic force, and it may play a role in periodontal remodeling.

BACKGROUND: A large number of cytokines produce in the periodontium on the tension side during orthodontic tooth movement, participate in periodontal remodeling, and make the tooth move to its normal position, thus achieving alveolar remodeling. Heat shock protein 27 (HSP27) is reported to be involved in the periodontal remodeling. OBJECTIVE: To investigate the expression of HSP27 in the rat periodontium on the tension side during the orthodontic tooth movement.METHODS: The rat models of orthodontic tooth movement were constructed using NiTi coil spring with the force value of 50 g. The periodontal samples were collected at 1, 3, 5, 7, 10 and 14 days after exerting force to detect the expression level of HSP27 in the periodontium on the tension side.RESULTS AND CONCLUSION: Immunofluorescence staining results revealed that the expression level of HSP27 in the periodontal tissues began to increase at the 1st day after exerting force, reached the highest level at the 3rd day, and then fell to the initial level at the 5th day. To conclude, HSP27 is evoked by orthodontic force early, and it may play a role in periodontal remodeling.

The improvement of quality management for medical equipment is an important part in overall quality management for modern hospital under the new circumstance of medical reform.The principles and approaches of evidence-based medicine were applied to quality management for medical equipment.In the view of generalized quality management,the core thoughts and basic framework of evidence-based quality management for medical equipment were put forward.The foundation of evidence-based management system was discussed including organization structure,PDCA quality management cycle,quality evidence procedure and overall quality-evaluating index system.

OBJECTIVE:To establish a HPLC method for determining the contents of rhein and emodin in Jianfei Jiangzhi tablets.METHODS:Stationary phase was Waters Symmetry C 18 (250mm?4.6mm;5?m),mobile phase was menthol-0.01%H 3 PO 4 (90∶10),detection wavelength440nm,flow rate1.0ml/min and column temperature30℃.RESULTS:There was good linearity in range of0.108?g～0.468?g for rhein and in range of0.180?g～0.480?g for emodin.The average recoveries of rhein and emodin were99.7%and98.6%respectively;RSD were1.93%and2.19%respectively.CONCLUSION:This method is rapid and accurate.It can be applied to effective control of the quality of Jianfei Jiangzhi tablet.

Objective This study aimed to study the effect of intra-brachial nitroglycerin administration via the angiography catheter on radial artery spasm in transradial percutaneous coronary intervention. Methods From patients undergoing transradial percutaneous coronary intervention (TRI) and succeeding in coronary angiography (CAG), 810 patients who needed percutaneous coronary intervention (PCI) (including Percutaneous Transluminal Coronary Angioplasty and/or stent implantation) were erolled, including 413 patients in the study group and 397 patients in the control group. When coronary angiography completed, positioned the angiography catheter over brachial artery and patients in the group received an administration of 400μg nitroglycerin via the angiography catheter. The control group received an administration of 400μg nitroglycerin via the sheath. The incidence of RAS were recored and compared. Resultes Baseline characteristics were similar between two groups. In the study group, the incidence of RAS was signiifcatively lower (18 vs. 33, P=0.021). Conclusions Intra-brachial nitroglycerin administration via the angiography catheter can prevent RAS during the insertion of guiding catheter in TRI.

Objective: To establish a GC method for the determination of content and content uniformity of memantine hydrochloride dispersible tablets.Methods: The sample was dissolved in water, alkalified by sodium hydroxide solution and extracted by methylene chloride.An HP-5 gas chromatography column (50 m×0.32 mm, 1.05 μm) was used.The column temperature was programming increased, and the initial temperature maintained at 120 ℃ for 3 min, and then raised to 220 ℃ at a rate of 10℃·min-1 and maintained for 7 min.A hydrogen flame ionization detector (FID) was used and the split ratio was 1∶1.The inlet temperature was 230 ℃ and the detector temperature was 260 ℃.The injection volume was 1 μl and the carrier gas was nitrogen with high purity at a flow rate of 3.0 ml·min-1.Adamantane was used as the internal standard, and the internal standard method was used for the calculation.Results: The calibration curve was linear over the range of 0.05-1.0 mg·ml -1 (r=0.999 7).The detection limit and the limit of quantification was 1.1 ng and 3.3 ng, respectively.The average recovery was 100.2% (RSD =0.73%, n=9).Conclusion: The method has the advantages of simple operation, small extraction process toxicity, little environmental pollution, high accuracy and high specificity, and can be used for the determination of content and content uniformity of memantine hydrochloride dispersible tablets.
