Objective To explore the effect of atorvastatin application on serum ferritin(SF)levels in elderly male patients with acute coronary syndrome(ACS)and its clinical significance. Methods 120 elderly male patients treated in Department of Cardiology in Cangzhou People's Hospital were randomly divided into treatment group and control group(60 cases in each group). All the patients in the two groups took the standard treatment of coronary heart disease,and the patients in treatment group were additionally given atorvastatin 20 mg orally,once-daily for 1 month. After 1 month of treatment,the changes in SF and lipid levels before and after treatment were determined. Results The total cholesterol(TC),low density lipoprotein(LDL)and SF levels of the two groups after treatment were significantly decreased compared with those before treatment. After treatment,triacylglycerol (TG)was decreased,and high-density lipoprotein(HDL)was increased significantly in treatment group,while in the control group,after treatment TG was increased and HDL was decreased. Compared between treatment and control groups after treatment,the differences in SF,TC,TG,HDL and LDL levels were statistically significant〔SF(μg/L):174.33±99.87 vs. 255.66±100.34,TC(mmol/L):4.23±0.60 vs. 5.15±0.56,TG(mmol/L):1.98±0.64 vs. 2.00±1.03,HDL(mmol/L):1.13±0.14 vs. 1.09±0.22,LDL(mmol/L):2.45±0.33 vs. 3.35±0.50,P<0.05 or P<0.01〕. Conclusion In elderly male hospitalized patients with ACS,the level of SF is significantly higher than normal,after atorvastatin specification treatment,the blood fat and SF levels are significantly lower,thus the SF inducing myocardial damage may be reduced and the risk of recurrence of acute coronary events can be decreased.

Objective To investigate the relationships between level of serum ferritin(SF)/blood lipid and the degree of coronary artery stenosis in elderly patients with acute coronary syndrome(ACS),and evaluate the value of SF in the diagnosis of coronary heart disease. Methods ①One hundred and twenty-five elderly patients with ACS(65 males,60 females)underwent coronary angiography examination,and the total cholesterol(TC), triglycerides(TG),high-density lipoprotein(HDL-C),low density lipoprotein(LDL-C)and SF were determined;according to the results of coronary angiography,the degree of coronary artery stenosis was obtained by using the Gensini score and the degrees of severity of stenosis were divided into three groups:light(42 cases),medium (45 cases)and severe(38 cases). The differences in levels of SF and blood lipids among the three groups were observed,and the relationships between the level of SF/blood lipids and various degrees of coronary artery stenoses were analyzed.②The elderly patients with ACS were divided into two groups,male and female,to compare the SF numerical value and Gensini score between the two groups. ③The SF numerical value and Gensini score of 65 senile male cases with ACS were compared to those of 60 middle aged male cases with the same disease. Results ①Variance analysis showed that SF,TC,LDL-C distribution had significant differences among light,medium and severe groups〔SF(μg/L):147.287±73.838,162.313±94.882,290.421±194.501;TC(mmol/L):4.423±0.900,4.998±0.740, 5.032±1.009;LDL-C(mmol/L):3.150±0.799,3.439±0.839,3.902±1.053,all P<0.01〕,while TG,HDL-C distribution among these groups had no such statistically significant differences(all P>0.05);in elderly patients with ACS,SF was positively correlated with Gensini score(r=0.355,P=0.000),while there was no correlation between Gensini score and any one of the following lipids:TC,TG,LDL-C,HDL-C(r=0.090,-0.170,0.256,-0.060,P=0.532,0.092,0.089,0.537).②The comparisons of SF value and Gensini score between senile male and senile female patients with ACS showed no significant differences(all P>0.05).③The comparisons of SF value and Gensini score between senile and middle aged male patients with ACS also showed no significant differences(all P>0.05). Conclusion The occurrence of ACS has certain correlation with SF and lipids,the degree of severity in coronary artery lesion is associated with SF,and there are no differences in age and sex in relation to the value of SF in the diagnosis of ACS.

Objective To investigate the change of HR,RR and arterial blood gas in the treatment of BiPAP ventilation in patients with acute pulmonary.Methods Fifty eight patients with acute pulmonary edema were randomized into two groups.The control group(n =29)were given conventional general treatment only,but treatment group(n =29)were given BiPAP ventilation besides conventional treatment.4 h later,heart rate (HR),respiratory rate(RR),SaO2,pH,PaO2 and PaCO2 were compared between the two groups.Hospitalization duration and incidence of invasive mechanical ventilation were recorded after discharge.Results Compared with pre-treatment,HR,RR,SaO2 and PaO2 in treatment group were improved significantly(HR 124 ± 12 beat/min vs 83 ±6 beat/min,t =5.372,P ＜0.01)(RR 37 ±5 beat/min vs 19 ± 8 beat/min,t =4.285,P ＜0.01)(SaO2 81.4％ ±5.4％ vs94.1％ ±4.2％,t=2.731,P＜0.05)(PaO2 53.2±5.4 mm Hg vs 89.1 ±8.5 mm Hg,t=5.763,P ＜0.O1).And these four indicators were also improved in control group after treatment,(HR 123 ± 10 beat/min vs 95 ± 8 beat/min,t =t =3.459,P ＜ 0.01)(RR 36 ± 7 beat/min vs 24 ± 6 beat/min,t =3.127,P ＜0.01)(SaO2 81.8％ ±5.7％ vs 88.3 ±4.5％％,t =2.314,P ＜0.05)(PaO2 53.5 ±4.6 mm Hg vs 72.8 ±9.5 mm Hg,t =3.756,P ＜0.01).HR,RR,SaO2 and PaO2 in treatment group were more significantly improved than that of control group(P ＜ 0.01 or P ＜ 0.05).Hospitalization duration in treatment group was significantly shorter than that of control group(9 d vs 15 d,t =3.763,P ＜ 0.01).The incidence of invasive ventilation were lower than that of control group too(but P ＞ 0.05.Conclusion These results suggested that BiPAP ventilation can regulate HR RR and blood gas value to accetable levels,shorten hoptipitalization duration and reduce the incidence of invasive ventilation.It is proved to be an effective therapeutic technique in the treatment of acute pulmonary edema patients.

In order to study the way of evaluating human performance under heat and cold stresses, we developed a wearable physiological monitoring system-intelligent belt system, capable of providing real-time, continuous and dynamic monitoring of multiple physiological parameters. The system has following features: multiuser communication, high integration, strong environment adaptability, dynamic features and real time physiological monitoring ability. The system uses sensing belts and elastic belts to acquire physiological parameters, uses WIFI to build wireless network monitoring for multiuser, and uses Delphi to develop data processing software capable of real-time viewing, storagng, processing, and alerting. With four different intensity-activity trials on six subjects and compared with standard laboratory human physiological acquisition instruments, the system was proved to be able to acquire accu-rate physiological parameters such as ECG, respiration, multi-point body temperatures, and body movement. The system worked steadily and reliably. This wearable real-time monitoring system for human heat and cold stresses can solve the problem facing our country that human heat stress and cold stress monitoring technology is insufficient, provide new methods and new ways for monitoring and evaluation of human heat and cold stresses under real task or stress environment, and provide technical platform for the study on human ergonomics.
