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.

Objective To explore influence of hypertriglyceridemia on serum NO ET-1 and the grade of the pathology severity in rats with severe acute pancreatitis. Methods 36 SD rats were randomly divided into 2 groups, group A (HLSAP group) , group B (SAP group). Severe acute pancreatitis was constructed by retrograde injection of 5% na-taurocholate. Blood samples were taken from all subjects to measure triglyceride, ET-1 and NO, pancreatic tissue samples were taken from head of pancreas and stained with H. E. , the degree of pancreatic damage was observed according to the point score of Schmidt and Pozsar's methods. Results In group A, the concentration of ET-1 increased more obviously than that in group B at 4 hour and 8 hour period(P ＜0. 05). The concentration of NO declined both in group A and group B at 12 hours period,but it had a great decline in group A. Animals with hyperlipidemia and severe acute pancreatitis developed significantly higher(P ＜0. 05) ET-1 than the animals of the non-hyperlipamic severe acute pancreatit group in 4 hours and 8 hours period. NO declined in group A and group B at 12 hours period, group A have significantly higher(P ＜0. 05) decline than group B in NO. The histological degree of pancreatic damage were significantly higher in group A than that in the group B at all times. Conclusions Mircrocirculation disorder had existed disorder in the early of SAP. Hypertriglyceridemia could incrase ET-1 and NO earlier and higher in severe acute pancreatitis, and then decline in the late stage. Hypertriglyceridemia intensified the pathologichistological degree of pancreatic damage.

AIM To express recombinant human cytochrome P450 3A4 mutants CYP3A4.3, CYP3A4.4, CYP3A4.5 and CYP3A4.18, and to employ them for in vitro metabolism studies of CYP3A4. METHODS Use Bac-to-Bac baculovirus expression system to recombinant baculovirus carrying cDNA of CYP3A4 mutants CYP3A4.3, CYP3A4.4, CYP3A4.5 and CYP3A4.18. Spodoptera frugiperda 9 (Sf9), cells were co-infected by recombinant viruses of CYP3A4 mutants, human NADPH-P450 oxidoreductase and cytochrome b5 to obtain recombinant proteins CYP3A4.3, CYP3A4.4, CYP3A4.5 and CYP3A4.18 with metabolic activity. RESULTS The mRNA transcription of CYP3A4 mutants in Sf9 cells were validated by RT-PCR. Testosterone and 7-benzyloxy-4-(trifluoromethyl) coumarin were metabolized by the lysates of Sf9 cells infected by the recombinant viruses. CONCLUSION CYP3A4 mutants CYP3A4.3, CYP3A4.4, CYP3A4.5 and CYP3A4.18 with metabolic activity were successfully expressed by baculovirus-insect cell expression system. The results indicated that recombinant CYP3A4. 5 showed lower activity comparing to the wild type protein towards testosterone, while CYP3A4. 18 with higher activity, and for CYP3A4.3 and CYP3A4.4 showing similar activity to the wild type protein.

OBJECTIVE:To establish a bacterial endotoxin test for ofloxacin injection METHODS:Interference tests in ofloxacin injection were performed with limulus test agents provided by different factories RESULTS:Ofloxacin injection did not interfer with bacterial endotoxin CONCLUSION:Bacterial endotoxin test can take the place of pyrogen test for ofloxacin injection

Objective To assess the effects of intraventricular conduction abnormality on left ventricular function in dilated cardiomyopathy. Methods The study composed of 3 groups,16 patients of dilated cardiomyopathy (DCM) without wide QRS complexes, 16 patients of DCM with complete left bundle branch block(CLBBB),and 16 age-matched healthy individuals,all showing sinus rhythm and being complicated with mitral regurgitation. Pre-ejection contraction time(PET), left ventricular ejection time(LVET), left ventricular filling time(LVFT), myocardial performance index(MPI), mitral regurgitation time(MRT), stroke volume(SV) were recorded with pulsed or continuous-wave Doppler. Pulse tissue Doppler imagining(TDI) was performed to measure the time dispersity of electromechanical motion of left ventricular in systole and diastole on the atrial-ventricular annulus with mapping techniques. Results Time dispersity of electromechanical motion of adjacent left ventricular segments in systole[((77.9)?(13.6))ms vs ((52.1)?(13.2))ms vs ((28.3)?(7.2))ms, P

The concept of golden mean (Zhong Yong), i.e. moderation, is the highest principle of moral cultivation in Confucianism. It entails an exclusive methodology in addressing politics, philosophy and everything in the universe. This concept has permeated into all aspects of traditional Chinese culture. As an ancient therapy, tuina is an important part of Chinese medicine and has its characteristic theory and methods. Just like Chinese medicine, tuina has long been greatly influenced by the concept of golden mean. To better promote the development of tuina, it’s necessary to investigate the historical evolution of tuina and the concept of golden mean as well as the influence of ‘golden mean’ idea on tuina manipulation, mechanism and treatment.

In recent years, there is some new recognition about the origin of prostatic carcinoma, prostatic carcinoma has been considered as a stem cell disease. Prostate cancer stem cells have close relationship with prostatic carcinoma formation, advancement, relapse, metastasis and drug resistance. As the development of science and technology continues, studies on the isolation and correlated phenotype identification of prostate cancer stem cells have lead us to further recognize prostate cancer stem cells, as well pave a new way for the diagnosis and therapy of clinical prostatic carcinoma.

BACKGROUND:Biomechanical studies on elderly subtrochanteric fracture by different fixation ways were more, but study on relatively proximal femoral nail antirotation-II (PFNA) and Asia 2 femur nail (A2FN) fixation for femoral subtrochanteric fractures in the elderly was less. OBJECTIVE:To study the biomechanical analysis of intramedul ary nail PFNA-II and A2FN fixation for elderly femoral subtrochanteric fractures. METHODS:Three-dimensional finite element models of femoral subtrochanteric fractures fixed by PFNA-II and A2FN in the elderly were established. Three-dimensional finite element analysis was used to analyze stress distribution and displacement after femoral subtrochanteric fractures by PFNA-II and A2FN fixation. RESULTS AND CONCLUSION:(1) The overal maximum stress, nail maximum stress and hip screw or spiral blade maximum stress values of PFNA-II intramedul ary fixation system were higher than that of A2FN intramedul ary fixation system. The distal locking maximum stress value and femoral head surface maximum stress values of PFNA-II intramedul ary fixation system were lower than that of A2FN intramedul ary fixation system. (2) The maximum displacement of PFNA-II intramedul ary fixation system was mainly concentrated in the large trochanter and femoral head pole. The maximum displacement of A2FN intramedul ary fixation system was mainly concentrated in the large trochanter. The maximum displacement of PFNA-II intramedul ary fixation system was higher than that of A2FN intramedul ary fixation system. The maximum axial displacement of PFNA-II intramedul ary fixation system was higher than that of A2FN intramedul ary fixation system. The maximum sagittal displacement of PFNA-II intramedul ary fixation system was higher than that of A2FN intramedul ary fixation system. The maximum coronal displacement of PFNA-II intramedul ary fixation system was higher than that of A2FN intramedul ary fixation system. (3) The lateral fissure, front fissure and rear fissure of PFNA-II intramedul ary fixation system were higher than that of A2FN intramedul ary fracture fixation system, but the difference was less pronounced. (4) The maximum stress value on fracture section of PFNA-II intramedul ary fracture fixation system was lower than that of A2FN intramedul ary fixation system. (5) Results showed that A2FN intramedul ary fixation system for intertrochanteric fractures has better biomechanical stability than PFNA-II intramedul ary fixation system for intertrochanteric fractures.
