Objective:To investigate the influencing factors and medication compliance of hypertension.Method: 3 grade-Ⅲand 15 grade-Ⅱgeneral hospitals in Anhui Province were selected by random sampling.732 outpatients with a hypertension course of 6 months or above were interviewed during July and October of 2004 with the medication compliance schedule.All data were input into computers with the software Epi info 6.04,and analyzed with SPSS 11.5.Result:①The medication compliance schedule had high reliability and validity,which could be used in the surveys of medication compliance of hypertension.②The medication compliance rate of the 732 patients was only 46.4%.③Trust in medical pro- fessionals,more attention paid to the disease,more knowledge of non-compliance harm,satisfactory family income,and longer consulting time were the common advancing factors in improving the medication compliance,but a longer duration of the medication regimen,a larger number of preparations and drugs,and higher frequency of taking medicine were the bloc- king factors.Conclusion:The medication compliance of hypertensives was generally not good,and it was influenced by many factors.It is necessary that medical professionals,patients,families and society all take part in its improvement.

Aim To explore the effect of 4-amino-2-trifluoromethyl-phenyl retinate(ATPR)on proliferation,differentiation activity in K562 cell line,and to research the mechanisms.Methods Cell proliferation was assessed by MTT assay.Cell differentiation index was analyzed by NBT reduction test.Morphologic changes were observed by Wright's staining in the light microscope. Cell cycle was determined by FCM.The mRNA expression of Cyclin D1,Cyclin E,CDK2,CDK4,CDK6,P21cip1,P27kip1,P57kip2,PCNA mRNA were detected by RT-PCR.While the protein expression of cyclin D1 and CDK4 was detected by Western blot.Results The growth of K562 cells was inhibited in a dose-dependent manner.NBT reduction test indicated that the ATPR could induce differentiation of K562 cells and increase the positive cell ratio.Morphologic changes were observed after Wright's staining using inverted phase contrast microscope.The proportion of cells in G0/G1 phase increased while S phase cells decreased.Cell cycle progression was blocked in the G1 phase.The expression of Cyclin E,cyclin D1,CDK2,CDK4,CDK6 mRNA decreased,while PCNA,P21 cip1,P27 kip1 change was not obvious,but P57 (kip2) mRNA expression was increased.Cyclin D1 and CDK4 protein expressions were reduced as well.Conclusions ATPR inhibits the growth of K562 cells and induces differentiation.P57 kip2 plays a key role in differentiation.Moreover,high level of P57kip2 is regulated via inhibiting its degradation through reducing proteasome-dependent proteolysis,and ATPR plays a role in cell cycle arrest.

The atomic force microscope (AFM) with an atomic resolution is a powerful tool for biological structure. The probe is an important part that determines the resolution of AFM. Carbon nanotube is becoming an ideal AFM probe due to its unique structure physical and chemical properties. Carbon nanotube AFM probes can be made by manual assembly or chemical vapor deposition. Several proteins, nucleic acids and cells have been investigated with carbon nanotube probes. Not only the high-resolution images but also the determination of specific DNA sequence and haplotype were acquired. Carbon nanotube AFM probe will increasingly play an important role in biological studies.

Objective:To explore the relationships among 4 primary indicators in the performance assessment and evaluation system of tertiary public hospitals.Methods:A questionnaire survey was employed to collect data on healthcare professionals'perceptions of the rationality of performance evaluation indicators.Structural equation modeling(SEM)and Amos 21.0 Statistical Software were utilized for data analysis,with the mediation effects tested using the Bootstrap method.Results:A total of 826 valid questionnaires were obtained.Medical quality,operational efficiency,and sustainable development had a positive impact on satisfaction.Operational efficiency and sustainable development played a chain-mediated role in the process of medical quality influencing satisfaction evaluation,namely"medical quality → operational efficiency → sustainable development → satisfaction".Conclusion:It helps to flexibly apply and deepen the integration of knowledge in the field of enterprise management into the field of hospital management,helps hospitals to scientifically formulate internal performance evaluation programs under the premise of limited resources,and provides new ideas for the country to optimize the performance appraisal index system of tertiary public hospitals.

Objective It explores the importance and effectiveness perception of 55 third-tier indicators in the cur-rent performance evaluation system.Methods From the perspective of those being assessed,it employs survey ques-tionnaires,Importance Performance Analysis(IPA),and focus group interviews to conduct research on the impor-tance and effectiveness perception.Results The overall perception of the importance and effectiveness of third-tier in-dicators is relatively high,and the performance evaluation indicator system can effectively assess the development level of level-3 public hospitals.There is a general discrepancy between the perception of importance and effective-ness.Some third-tier indicators face issues of insufficient perception of both importance and effectiveness.Conclu-sion Performance evaluation policy formulation based on the implementation of policies and after excluding the scores of indicators closely related to stakeholders can re-monitor and analyze indicators.This allows for the addition or removal of third-tier indicators,adjustment of indicator weights,optimization of indicator content,precision in mea-suring indicators,and improvement of the performance evaluation effectiveness of level-3 public hospitals.
