Chinese Journal of Practical Internal Medicine 2000;0(11):-
Objective To explore the change of plasma orexin-A levels in patients with chronic obstructive pulmonary disease(COPD).Methods Lung function test and blood gas analysis were performed in 15 obese COPD patients,20 COPD patients without obesity,20 obese controls and 20 normal healthy adults(control group).In both obese COPD group and obese group,the body mass index(BMI)was higher than 25 and there was no significant difference in BMI.The plasma was deproteinized by chromatography,and the plasma orexin-A levels were determined by radioimmunoassay.Results The plasma orexin-A levels in the obese COPD group[(8.82?1.90)ng/L]and the non-obese COPD group[(8.69?1.84)ng/L]were significantly higher than those in the obese group[(7.18?1.45)ng/L(P 0.05).Plasma orexin-A levels in patients with COPD correlated negatively with partial pressure of oxygen(PaO_2)(r = -0.527 ,P

Objective To investigate the effect of low molecular weight heparin calcium combined with breviscapini in treating a-cute exacerbation of elderly chronic pulmonary heart disease and its mechanism.Methods 86 patients with acute exacerbation of elderly chronic pulmonary heart disease in our hospital from October 2011 to June 2013 were randomly divided into two groups. There were no significant differences in age,gender and disease condition between the two groups.44 cases were in the therapy group and the other 42 cases were in the control group.Both two groups received the routine therepy.On this basis the therapy group was added with low molecular weight heparin calcium and breviscapini.Then the improvement of clinical symptoms and the changes of plasma nitric oxide (NO)and endothelin-l (ET-1)after treatment were observed in the two groups.Results The total effective rates in the therapy group and the control group were 90.1%and 71.4% respectively;the levels of plasma NO and ET-1 after treatment in the two groups were significantly improved,but the improvement in the therapy group was better than that in the control group with the statistical difference between them(P <0.05).Conclusion Low molecular weight heparin calcium combined with breviscapini can significantly improve the symptoms in the ederly pulmonary heart disease,decrease the lung arterial press,re-lieve the load of right ventricle and affect the levels of plasma NO and ET-1 with less adverse reactions.

Objective To find out factors influencing voluntary blood donation activities and establish the most appropriate method for recruiting blood donors. Methods Questionnaire investigation of donors and data analysis by SPSS+ software. Results In Chengdu city, 2385 residents' knowledge on nonrenumerated blood donation was as follows: among the 2385 residents, the percentage of people who knew the government policies of blood donation was high (87.5%), but the percentage having common knowledge of blood donation was only 29.4%, of risk behavior was 32.5%. Among the 1349 participants who had donated blood, the percentages having common knowledge of blood donation and risk behavior were 33.4% and 38.1% respectively, compared to the 1036 participants who never donated (24.2% and 25.1%, respectively)(P

Objective To form the basis of establishing a strategy for safe blood donor recruitment and to identify and subdivide the structures of donors.Methods Demographic data of blood donors, and blood testing results of HBsAg, anti-HCV, anti-HIV, and syphilis, from Nov. 2004 to Jun. 2005, were collected and analyzed.Results Among the 45270 voluntary blood donors, the total positive test rate were 3.11%, which was related to age, level of education and occupation of blood donors. About 76.7% of donors were young people, aged from 18 to 30. As the age increased, female donors were less than male ones. Among all the donors, 81.6% received higher education, which had lower positive test rate than those with lower level of education. Among the 45270 donors, farmers had the highest positive test rate; workers and service people came the second; students and medical staff had the lowest. As to donors with incomplete record, the positive test rate was higher than those with complete record.Conclusion During blood donor recruitment, quality control is important. People younger than 30, with student or higher education background, are relatively safe to recruit.

Objective To investigate the relationship between myeloperoxidase(MPO) and ankle brachial index(ABI) in patients with htypehypertension.Methods A total of 133 patients were enrolled in this study,and divided in to htypehypertention group(n=72),non-htypehypertension group(n=30) and normotension group(n=31).Their Hcy,ABI and MPO levels were measured and compared.Results The ABI in htypehypertention group and non-htypehypertension was significantly lower than that in normotension group (P<0.05),ABI in non-htypehypertension group was lower than that of htypehypertonsion group(P<0.05).MPO and CRP in the htypehypertension group was significant higher that those of normotension group(P<0.05).The ABI was negatively related with the serum MPO and CRP levels in htypehypertention group (r=-0.712,-0.722,P<0.05).Conclusion ABI is closely related with MPO,and play an important role in diagnosis of artery function impairment and high risk of htypehypertension patients.

Objectives To investigate the clinical features of Guillain-Barré syndrome (GBS) in children from Shen-zhen. Methods The clinical manifestations, results of electrophysiological tests and prognosis of 28 GBS patients from July 2002 to July 2012 were retrospectively analysed. Results Of 28 children, 16(57.1%) had preceding acute upper respiratory infection for 3-14 days but no patient had acute gastroenteritis. One had received HBV vaccination in 2 weeks before the onset of GBS. The peak season for GBS is spring. According to the clinical presentations and the neurophysiological results 17 patients had demyelinating neuropathy, 5 acute motor axonal neuropathy, 2 acute motor sensory axonal neuropathy, 3 Miller-fisher syndrome, and 1 polyneuritis cranialis. 14 (50.0%) patients suffered from pain in limbs which is the most nota-ble symptom in the early stage. Intravenous immune globulin (IVIG) and steroids were given during the acute phases in the majority of the patients, and assisted ventilation was performed in 2 patients due to respiratory muscle paralysis. No diffe-rence was found in Hughes scores, average hospitalization durations, and the prognosis between patients with GBS variants patients and patients with classic GBS. Conclusions Children with GBS in Shenzhen area have different clinical features.

Objective To design a kind of aseptic drainage device with safe practice and accurate measurement for clinical nurses. Methods The experiment group included 63 cases using drainage device with accurate measurement,and control group included 63 cases using disposal drainage bag with scale of visual measurement.The accuracy of drainage liquid measurement was compared between two groups,and bacterial culture was made for the drainage liquid of two groups.Results The measurement error of experiment group and control group was(3.31±1.8)mL and(56.0±5.8)mL,respectively.The difference was significant(t=-4.593,P<0.01).The bacterial culture results showed no obvious difference between two groups(positive rate were 15.9%vs 17.5%,χ2=0.057,P>0.05). Conclusion The accurately measured aseptic drainage device is convenient for nurses to practice in clinics,and its application can reduce workload of nurses and decrease the occurrence of pollution.
