OBJECTIVE To investigate the reasonable use of antibacterial in department of orthopedics.METHODS The patients in our department were registered according to the inventory of antibacterial use made by the hospital infection monitoring network of Medical Administration Bureau,Ministry of Health of the People′s Republic of China,the(operative) incision was classified according to Clinical Surgery.The data of reasonable use of antibacterial were(obtained) after evaluation and(analysis).RESULTS Of the 257 patients in our study,79.37% of them were used antibacterial,20.62% were not used antibacterial,24.50% were used antibacterial for therapy,75.49% were used antibacterial for infection(prevention);95.09% were used systematically;74.50% were reasonable(usage,) 25.49% were unreasonable usage;of the 204 patients who were used antibacterial,only 34 patients were tested by drug sensitivity trial,and the others were used by experience.CONCLUSIONS In order to use antibacterial reasonably,we suggest two points,one is that the medicine management department should workout a feasible antibacterial use institution and mass(evaluation) criterion,take mass examination regurally,and connect the bonus to the examination result;the other is that we should enhance the management of antibacterial market,avoid the improper competition,rise the morality view of the doctor,and suggest them to use antibacterial reasonably(according) to the scientific theory.

OBJECTIVE To study the characteristic of the lower respiratory tract infection in patients with the cerebral hemorrhage and hypertension,and find out the measures of prevention and control. METHODS The discharged patients with the cerebral hemorrhage and hypertension from Jan 2002 to Dec 2004 underwent retrospective investigation and analysis for the sites and reasons and the results of bacterial culture. RESULTS The incidence of the lower respiratory tract infection in patients with the cerebral hemorrhage and hypertension was 55.55%.Major infection factors correlated with neurogenic pulmonary edema, irritable hyperglycemia,bulbar paralysis,etc.The Gram-nagative bacteria were predominant among the pathogens. CONCLUSIONS The infections are interrelated with many factors.Abiding by the principle of using antibiotic and the strict aseptic manipulation may reduce the occurrence of the infection,but treating the primary affection and the comprehensive therapy are important measures for reducing infection.

Objective To investigate the correlation of serum ereatine kinase iseenzyme-MB (CK-MB) and recent cardiac events(30 days, 180 days) and late cardiac events (360 days) in patients with acute coronary syndrome (ACS). Methods Serum creatine kinase (CK) and CK-MB in 168 patients with ACS were measured, and these patients were divided into four groups according to the levels of CK and CK-MB. The occurrence of cardiac events analysis of CK and CK-MB was followed up for 30, 180 and 360 days and the relationship between the occurrence of cardiac events and the levels of CK and CK-MB were studied. Results There was statistical correlation between increased CK-MB and abnormal ECG Q wave, ST segment change (P< 0.05), 168 patients had followed up 30, 180 and 360 days, in which cardiac events happened in 57 common patients (64 examples), 27 examples (16.1%) happened in the recent cardiac event, and 37 examples(22.0%) happened in the late cardiac event. The cardiac event and CK-MB elevation had statistical correlation (P<0.05). Conclusion ACS patients with increased CK-MB levels prompt a poor prognosis, and could be an independent indicator of recent and late cardiac events in patients with ACS.

Objective To investigate the effect of estrogen on expression of matrix GLA protein (MGP)in ovariectomized Sprague-Dawley(SD)rats and the role of estrogen in improving postmenopausal osteoporosis.Methods Thirty-six SD female rats were allocated into 3 groups randomly,every 12 rats in ovariectomized group(OVX group),estrogen group(E group)and control group(sham group).Rats in OVX and E group all underwent bilateral ovariectomy,those rats in E group were given by estradiol benzoate intramuscularly after 3 weeks of ovariectomy.Rats in sham group underwent bilateral lipectomy near the ovary.All rats were kept the urine and the serum every three weeks and were sacrificed after 15 weeks.The pathology changes of uterus,lumbar vertebral bones were observed by immunohistochemistry.Bone mineral density(BMD)of lumbar vertebra of rats was determined by dual energy X ray absorptiometry(DEXA).The content of MGP in serum and urine was determined by ELISA.Expression of underearboxylated matrix GLA Protein(MGP)was detected by immunohistochemistry.Relative quantification of MGP mRNA expression in lumbar vertebra bone was detected by Fluorescent real-time quantitative polymerase chain reaction.Results(1)After 15 weeks of ovariectomized,the endometrium of uterus and lumbar vertebra exhibit remarkable pathologic changes in OVX group.The serum estrogen of(454±66)pmol/L in OVX group were lower than in(527 ±77)pmol/L in sham group and(556 ±80)pmol/L in E group significantly (P ＜ 0.05).The BMD of lumbar vertebra of(0.263 ± 0.030)g/cm2 in OVX group were lower than (0.295 ±0.024)g/cm2 in sham group and(0.279 ±0.024)g/cm2 in E group significantly(P ＜0.01).(2)The serum MPG protein in OVX group and E group showed decreased trends after ovariectomized,which were(104 ±64)ng/L in OVX group and(134 ±6)ng/L in E group at 9 weeks,which reached statistical difference(P ＜ 0.05).However,MGP in urine in sham group did not exhibit significant difference after 15 weeks of surgery(P ＞0.05).The MGP in urine of E group showed increased trends after 12 weeks of surgery,which reached(110.0 ±3.4)ng/L at 15 weeks,in the mean time,it was found that(86.5 ±2.5)ng/L of MGP in urine in OVX group,which showed significant difference(P ＜ 0.05).(3)MGP could be observed in lumbar vertebra in OVX group by immunochemistry staining.In the other two groups,the expression of MGP was not dominant.(4)Relative quantification of MGP mRNA expression in lumbar vertebra was defined as 1 in OVX group,when compared with 0.289 ±0.260 in E group and 0.103 ±0.098 in sham group,the difference showed statistically significant(P ＜ 0.01).Conclusion Estrogen could increase the expression of MGP mRNA and protein in ovariectomized rats and might play an important role in improving postmenopausal osteoporosis.
