Objective To observe indicators of hemorheology and blood gas analysis of COPD( chronic obstructive disease) patients complicated by CI(cerebral infarction) in acute exacerbation time and the relationship between them.Methods 46 patients with COPD complicated by CI in acute exacerbation time(complications group) and 44 patients with COPD in acute exacerbation time(COPD group) blood rheology indicators,fibrinogen(Fg) ,D-di-mer(DD) and blood gas analysis were detected.And 45 cases of health-related physical check (control group) were recruited for comparison.Results Compared with the control group,complication group,COPD group of whole blood viscosity,plasma viscosity,hematocrit,platelet adhesion rate,Fg,and DD levels were significantly increased,the difference was significant(P<0.05) ;The complications group of whole blood viscosity,Fg,and DD levels were significantly higher than COPD group;Fg and DD and blood PaCO2 correlated( r Fg =0.36,P<0.01 ,rDD =0.510,P<0.01).Conclusion Patients with chronic obstructive pulmonary disease and cerebral infarction in acute exacerbation time had abnormal coagulation status,and improving ventilation and early application of anticoagulant drug therapy,could reduce the chronic obstructive pulmonary disease,the occurrence of cerebral infarction.

Objective To investigate and analyze the characteristics of stressor that the undergraduate nursing students have to face at the clinical work in grade A hospitals , then to provide the scientific basis for clinical teaching management and reduce the pressures of undergraduate nursing students. Methods Questionnaires werehanded outto 80 undergraduate nursing students and datawere collected in the condition of their consents. Results The undergraduate nursing students had the higher scores on the dimensions of Patient Care and Nursing Work and stayed the pressure above average. Male and female undergraduate nursing students had the different top 5 stressors, the difference was statistical significance (t=2.434-3.644, P < 0.05). Conclusions The clinical teaching should care for the different stressors of male and female to reduce work and psychological pressure by taking effective measures, and give more attention to strengthen capacity-building of professional practice.

OBJECTIVE:To provide reference for establishment of delivery way of essential drugs in China.METHODS:Related information and literatures were reviewed in order to analysis the characteristics of 3 kinds of delivery ways,i.e.Songjiang Shanghai delivery way,Beijing community medicine delivery way,Zhejiang community delivery way from background,the difficulty of actualization,pros and cons of the delivery way.RESULTS & CONCLUSION:3 kinds of delivery ways which have their own advantage and disadvantage should be adopted according to actual situation.The government of provinces may summarize the experience and innovate to establish a delivery way of essentical drugs.

Objective To explore the clinical significance of combined detection of serum procalcitonin (PCT)and interleukin 6 (IL-6 )in patients with lower limbs long bone open fractures before and after emergency debridement fixation and postoperative reg-ular antibiotics treatment.Methods Patients with lower limbs long bone open fractures within 8-24 h after injury were divided in-to wounds fester group,wounds contamination group and wounds non-contamination group.Serum PCT and IL-6 levels were detec-ted and compared between patients group and control group.Results Before treatment,PCT and IL-6 levels in wounds contamina-tion group and wounds fester group were higher than control group (P<0.05 or P<0.01),but those in wounds non-contamination group were not different with control group (P>0.05).After treatment,PCT and IL-6 levels in wounds fester group and wounds contamination group were decreased,but those in non-contamination group were with a trend of fluctuation.In the first day of treatment,PCT and IL-6 levels in contamination and fester group were higher than control group (P<0.05 or P<0.01),but there was no significant differences,compared with the levels before treatment(P>0.05).PCT and IL-6 levels in non-contamination group,compared with control group and levels before treatment,were not significantly different (P>0.05).In the third day of treatment,PCT and IL-6 levels in the three patient groups were higher than control group (P<0.05 or P<0.01).PCT and IL-6 levels in fester and contamination group were not significantly different with the levels before treatment (P>0.05).PCT and IL-6 levels in non-contamination group were significantly higher than the levels before treatment (P<0.05).In the fifth day of treat-ment,with the improvement of disease condition,PCT and IL-6 levels decreased significantly.PCT and IL-6 levels in fester and contamination group were significantly higher than control group (P<0.05),but lower than the levels before treatment (P<0.05).PCT and IL-6 levels in non-contamination group were higher than control group and the levels before treatment (P>0.05). Conclusion Wounds infection could onset in patients combined with lower limbs long bone open fractures and soft tissue open inj u-ry.Dynamic monitoring of PCT and IL-6 levels might be significant for early prediction of bacteria infection,rational use of antibi-otics and promote healing of wounds and fractures.

The author earmarked institutional defects as the key to China's medical and health system reform during the economic reform.Main progress and fruits of this reform during the past three years are listed as follows:theory and system innovation,initial establishment of the primary healthcare security system of nationwide coverage,establishment and implementation of the essential drug system,establishment and perfection of the primary healthcare system,equity of primary public health service,and general startup of public hospitals reform.In addition,the author identified such reform roadblocks and challenges as growing conflicts between the demand and supply of healthcare services,resistance for furthering the system reform,conflicts in drug production and circulation,lack of top-tier design for public hospital reform,and lack of systematic planning for talent development.

Objective To observe the clinical efficacy of Tongxinluo Capsule on hypertension with interaction of phlegm and blood stasis, context stagnation or Qi deficiency and blood stasis, and its impact on blood rheology. Methods One hundred and forty-seven cases of hypertension were randomly divided into treatment group (74 cases) and control group (73 cases). Both groups were given conventional antihypertensive and lipid-lowering treatment, and the treatment group was given Tongxinluo Capsule additionally. Symptom score, blood pressure, lipid and rheology of two groups were observed before and after treatment. Results There was no significant difference between before and after treatment in hemorheology and blood lipid of two groups (P

29 aged patients of transvenous endocardial pacemaker implantation have been performed during 1981-1988. Elderly group consisted of 29 cases with 19 males and 10 females with age ranging from 60-86 years. The indications for permanent pacing in this series included. (1) Sinus bradycardia (2 cases), (2) Sinus bradycardia, sinus arrest and/or sinoatrial block (2. cases), (3) Brady-tachyarrhythmia (It cases), (4) Bifaseicular block (2 cases), (5) Trifascicu lar block (3 cases), and (6) Complete AV block (9 cases). All 29 cases were symptomatic (syncopal attacks). They required permanent pacing. They have been followed up for 2 to 90 (average 39) months. The incidence of complications has been relatively low. A pacing mortality during the follow-up period was not seen in this series.A clinical assessment was made with emphasis on some special features in elderly individuals. In the elderly bradyarrbythmia was usually due to fibrosis and sclerosis of the conduc-tion system rather than to ischaemic heart disease. In the elderly the implantation of a pacemaker was indicated for any symptomatic bradycardia. Age was not a contraindication for permanent pacing
