To provide an effective approach to select, develop, interpret and apply well-designed quality indicators. Then to promote the continual improvement of laboratory quality and to assure patient safety. We focused on the quality cycle of selecting, development, implementation and processing for quality indicators. And some examples for essential activities in the development and use of quality indicators were shown. Through the presentation of process and examples, we put forward an organized approach that provides the laboratory with a plan to structure its development of quality indicators to gather useful information. Quality indicators are important. However, they should be integrated with internal review plan, External Quality Assessment (EQA) and the process of activities in plan. Only then can we really promote the continual improvement of quality.

ObjectiveTo evaluate the two common anesthesia techniques used in the hip joint replacement surgery (HJRS) and provide references to the most reasonable choice for them. MethodsTo undertake a retrospective study on 34 patients that received continuous epidural anesthesia(CEA) or combined intravenous and inhaled anesthesia(CIIA)respectively in HJRS. Results and Conclusions CEA had higher incidence of bone cement reaction than that of CIIA, whereas there was no significant difference in blood loss and the anesthesia efficacy between them. CIIA seemed to be easier to be performed. CIIA sounds more reasonable than CEA in HJRS although both of them are safe anesthesia techniques.

BACKGROUND: Some studies have revealed that plasma levels of D-dimer and fibrinogen are closely related to blood coagulation status before any occurrence of cardiovascular disease and cerebrovascular disease.OBJECTIVE: To investigate the difference in plasma levels of D-dimer and fibrinogen, two markers of prethrombosis, between elderly patients with cardiovascular or cerebral vascular disease and elderly and younger healthy persons.DESIGN: Case analysis based on patients.SETTING: Cadre ward of a military general hospital of Chinese PLA.PARTICIPANTS: From October 2000 to March 2002, 153 patients with cardiovascular disease and 116 patients with cerebral vascular disease, aging over 60 years, hospitalized in the Second Cadre Ward of the General Hospital of Shenyang Military Area Command of Chinese PLA were selected into this study. Meanwhile, healthy persons with normal results of physical examination conducted in this hospital were selected as controls. Of all the control persons,68 with an age less than 60 years were allocated into the younger control group and the other 98 persons were allocated into the elderly control group.METHODS: On the second day after hospitalization, a venous blood sample was taken from each patient. For those receiving medications of aspirin, their venous blood samples were taken on the 4th day after withdrawal. The plasmas of the samples were measured by using STA Compact, a fully automatic coagulation analyzer(Diagnostica Stago) and the auxiliary kit. The level of D-dimer was detected by employing the immunoturbidimetry assay(ITA) And the concentration of fibrinogen was measured by using the magnetic bead technologies.MAIN OUTCOME MEASURES: The plasma levels of D-dimer and fibrinogen were detected in each group.RESULTS: All the 435 participants entered the statistical analysis procedure. The plasma levels of D-dimer and fibrinogen of elderly control group [(0.91 ±0.51) mg/L and (3.69±1.25) g/L] were significantly higher than those of the younger control group[0.48 ± 0. 15) mg/L and(3.12±0.76) g/L] (t=2.39-2.66, P ＜ 0.05) .The plasma levels of D-dimer and fibrinogen of the elderly cardiovascular group [ (1.35 ± 0. 72) mg/L and(4. 16 ± 1.30) mg/L] and the elderly cerebral vascular group [(1.16±0.98) mg/L and(4.05±1.98) g/L]were significantly higher, as compared with the elder control group and the younger control group( t = 4.23-5.41, P ＜ 0.01 ).CONCLUSION: Compared to the younger control group, the plasma levels of D-dimer and fibrinogen of elderly population increase significantly, especially in those with cardiovascular disease or cerebral vascular disease.

BACKGROUND: Hyperlipemia is one of the important risk factors of coronary atherosclerotic cardiopathy. Great attention has been paid on how to explain the correlation between blood lipid and coronary heart disease and the correlation of characteristics and level of blood lipid with coronary heart disease.OBJECTIVE: To probe into the correlation among the characteristics, the level of blood lipid and coronary heart disease in senile people.DESIGN: Case-control observation and stratified analysis.SETTING: Second Cadre Ward of General Hospital of Shenyang Military Area Command of Chinese PLA.PARTICIPANTS: Totally 105 inpatients were selected in coronary heart disease group, diagnosed as coronary heart disease, tallied with WHO Diagnostic Standard on Coronary Heart Diseases, in Second Cadre Ward of General Hospital of Shenyang Military Area Command of Chinese PLA from January 2001 to January 2002. Totally 99 inpatients, by checked, without coronary heart disease and cerebral vascular disorder were selected in the control in the same period.METHODS: 2 mL venous blood was collected in fasting in the morning and the serum was collected after centrifuged at 3 000 r/minute, for 5 minutes. Auto-biochemical analyzer and enzyme kit were used to determine cholesterol, triglycerin, high density lipoprotein cholesterol and low density lipoprotein cholesterol. Compared with the data in the control, the ranges of cholesterol, triglycerin and low density lipoprotein were calculated successively and divided by 10; at the class intervals of 0.53, 0. 39 and 0.29 mmonl/L, the frequency table was worked out. According to the frequency table, P25 (the 25th percentile), P50 (the 50th percentile), P75 (the 75th percentile) and P90 (the 90th percentile) of cholesterol, triglycerin and low density lipoprotein cholesterol were calculated successively. The stratified groups were divided based on P ＜ 25, P25 to PS0, PS0 to P75, P75 to P90 and ＞ P90, by which, the cases belonging to 5 groups were determined in coronary heart disease group and the control respectively. The exposure factor was determined by ＞ P90, compared with other 4 groups, Menta-Haensecel method was used to calculate x2. If the exposure factor was related with coronary heart disease, the relevant coefficient and 95% confidence interval should be calculated. In accordance with the standards (Proposal on Prevention of Abnormal Blood Lipid and Targets of Abnormal Blood lipid on 2-grade Prevention of Coronary Heart Disease), the cases beyond the targets and morbidity were determined in two groups.MAIN OUTCOME MEASURES: Determination of blood lipid, abnormal cases and morbidity in two groups; cases beyond targets of blood lipid and morbidity; stratified comparisons of percentiles in two groups.RESULTS: According to intention measurement, 204 cases entered result and the control, there was no significant difference in cholesterol, triglycerin cases presented hypercholesterolemia, 34.3% cases hypertriglycerlipidemia and 11. 4% cases low density lipoprotein-hypercholesterolemia. It was indicated that the blood lipid was in the normal range among 64. 8% to 88.6% comparison between the cases with cholesterol ≥5.47 mmonl/L and the cases with cholesterol varied from 3.85 to 4.63 mmol/L, the morbidity of coronary heart disease in the former was 2.98 times as high as the latter (x2 = 6.29, 95% confidence interval was 1.27 -6.98) . In the comparison between the cases with cholesterol ≥ 5.47 mmol/L and the cases with cholesterol varied from 4.64 to 5.05 mmol/L, the correlation with coronary Lipid for 2nd Prevention of Coronary Heart Disease, among the patients with coronary heart disease, cholesterol ≥ 4.68 mmonl/L in 54. 2% cases,triglycerin ≥ 1.70 mmol/L in 34. 3% cases and low density lipoprotein ≥ 2.6 mmol/L in 52. 3% cases.CONCLUSION: For senile patients with coronary heart disease, the satisfactory level of cholesterol is 3.85- 4.63 mmol/L. For those with cholesterol ≥ 5.47 mmol/L, compared with those varied from 3.85 to 4.63 mmol/L, the morbidity of coronary heart disease in the former is possibly 2.98 times as same as the latter(x2 = 6.29, 95% confidence interval was 1.27 - 6.98).

Objective:To investigate the anesthetic choice for patients undergoing cesarean section complicated with placenta implantation.Methods: A retrospective case review of the patients with placenta implantation between 2008 and 2013 at Peking University Third Hospital was conducted in the International Classification of Diseases (ICD)-9 codes,excluding natural birth and not first diagnosed in our hospital,a total of 96 cases were incorporated into this study.According to the degree of implantation,they were divided into three groups: accreta group,increta group and percreta group.We analyzed the time from the start of surgery to baby delivery and the anesthetic technique.Results: The accreta group included 49 cases,the increta group 33 cases,and the percreta group 14 cases.The average time from the start of surgery to fetus delivery in the three groups were (6.7±3.0) min,(7.2±4.6) min,and (11.9±4.9) min,and the percreta group was significantly different from the accreta group and the increta group (P<0.05).There were significant differences among the three groups in anesthetic choices (P<0.001): in the accreta group,45 cases (91.8％) underwent spinal anesthesia,2 cases (4.1％) underwent general anesthesia,and 2 cases (4.1％) were converted to general anesthesia after spinal anesthesia during the operation;in the increta group,22 cases (66.7％) underwent spinal anesthesia,4 cases (12.1％) underwent general anesthesia,and 7 cases(21.2％) were converted to general anesthesia after spinal anesthesia;in the percreta group,2 cases (14.3％) underwent spinal anesthesia,2 cases (14.3％) underwent general anesthesia,and 10 cases (71.4％) were converted to general anesthesia after spinal anesthesia.Conclusion: Spinal anesthesia can be used as the first choice of cesarean section complicated with placenta implantation and general anesthesia should be considered in placenta percreta.
