The blood and urine estrogen (E2) and progesterone (P) were measured in 133 patients with fibrocystic disease (FCD) of breast and 17 healthy subsjects during menstrual cycle phases. According to the characteristics of the secretion, the patients were divided into five types. Type A (54 patients): The secretion peak of E2 and P appeared beforehand and secretion of P was prolonged and E2 decreased significantly in ovulatory phase. Type B (16 patients): The secretion peak of E2 disappeared in ovulatory phase although the secretion of P was normal. Type C (16 patients): The secretion peak of P deferred its disappearance and maintained at higher level till pre-menstrual period and sc did E2: the secretion of E2 decreased in ovulatory phase. Type D (41 patients): The secretion peak of E2 in ovulatory phase was normal but could not return to normal level in pre-menstrual period, in the mean time the secretion of P also deferred its disappearance. Type E (6 patients): There was no secretion of P and the blood and urine concentrations of E2 deccreased in all phases. The average value of E2 in the patients with FCD was compared with that of healthy subjects. The concentration of E2 in all the patients increased in follicular and pre-menstrual phases. However, the concentration of E2 in ovulatory phase was much lower in the patients than in healthy subjects.

The expression and activity of CYP2C9 and CYP2C19 enzymes are different at different ages, which has a direct effect on clinical drug use in pediatric patients. It has vital significance to further research the change rules of CYP2C9 and CYP2C19 and the influence of gene polymorphism on drug metabolism in the process of development for improving the efficacy and rationality of pediatric medication.

Objective This study is to identify the presence of superoxide anion-generating system in human lens epithelial cells using arachidonic acid (AA) as the stimulator.Design Experimental study.Participants Human lens epithelial cells B3 (HLE B3). Methods Confluent human lens epithelial cells (HLE B3) were subjected to stimulation by AA and its derivatives.The generation of su- peroxide anion was quantified with a luminometer (LumiStar BMG) immediately upon AA and its derivatives addition.Cells preloaded with superoxide dismutase (SOD) or mannitol were used as negative controls and cells mixed with 3% ethanol (solvent for AA) were used as baseline.Cells were preloaded with inhibitors 30 minutes before luminometer measurement.A time-and concentration-depen- dent study on the AA-stimulated activation of mitogen-activated protein kinase (MAPK) was carried out using western blot analysis. Main Outcome Measures Superoxide generation,phosphorylation of MAPK.Results AA at dosage of 30-150 mM proportionally in- duced luminescence in HLE B3 cells,but was ineffective in cells preloaded with SOD or mannitol.DPI,a non-specific NADPH oxidase inhibitor eliminated AA-induced superoxide anion generation partially.Leinoleic acid,stearic acid,eicosa-11Z,14Z,17Z-trienoic acid (20:3) and eicosa-11Z,14Z-dienoic acid (20:2) were ineffective.The generation of superoxide anion was not contributed by cyclooxyge- nase or the cytochrome p450 pathway since indomethacin (inhibitor for cyclooxygenase) or ketoconazole (inhibitor for cytochrome p450) could not eradicate the stimulatory effect of AA.While CDC,a specific inhibitor for lipoxygenase could eliminate superoxide generation partially.The specific inhibitor for 5-lipoxygenase AA861 completely blocked the generation of superoxide anion.Western blot analysis of the cell lysate showed that AA at the concentrations of 30-150 mM progressively activated ERK and JNK.They were transiently ac- tivated between 2.5-30 minutes.The activations of ERK and JNK were dose-dependent and time-dependent.Conclusions Inhibition of superioxide anion generation may be a new approach to block lens epithelial cell proliferation and post-capsule opacification.

Cerebral palsy (CP) is one of the most common causes of physical disability among children all over the world.It is often accompanied by hypophrenia,epilepsy,abnormal behaviors,visual auditory disorder,emotional disturbance,facial disfunction,developmental delay,malnutrition,poor lung function,hypoimmunity,and so on.Also hip abnormalities are important issues.The hip subdislocation,dislocation and pain largely influence the daily life of the patients.Early detection and therapy offer a great hand to ease the degree of disability and enhance rehabilitation effect.Surgical management and rehabilitation training have significant count on maintaining the hip function and improving daily life quality.The lesion severity,treatment timing,individual differences and cooperation degree of parents are main factors of prognosis.This contribution summarizes the symptoms,radiographic parameter changes and treatments of CP.

Objective To study the effect of clopidogrel on intimal hyperplasia of rabit arta injured by balloon and its mechanism.Methods Twelve New Zealand rabbits were established as atherosclerosis plaques rupture models and were evenly divided in to the high-cholesterol group and the clopidogrel group.Another 6 rabbits were set as the control.Serum cholesterol and triglyceride levels were taken in the beginning,before and after surgery.Meansurement alsincluded the changes in macrophage count and collagen levels in the plaques,changes of plasma fibrinogen and P-selectin levels as well as changes in activity of t-PA and PAI-1.The changes of intima thickness and the degree of stenosis were recorded.Results Compared to the control group,the high-cholesterol group and the clopidogrel group had higher average macrophages count and collagen levels in the plaques.The clopidogrel group had less macrophages count in the plaques than the high-cholesterol group;however,the clopidogrel group had higher levels of collagen in the plaques than the high-cholesterol group.The plasma level of P-selectin reduced in the clopidogrel group after plaques rupture.The activity of t-PA remained uncharged in the clopidogrel group but increased in the high cholesterol group.Compared to pre-treatment level,the activity of PAI-1 increased in the high-cholesterol group but reduced in the clopidogrel groups after atherosclerosis plaques rupture.The thickness of vessel intima increased in both the high-cholesterol group and the clopidogrel group,however,the degree of intima thickening and vessel stenosis is less in the clopidogrel group compared to the high-cholesterol group.Conclusion Clopidogrel relieves inflammation reaction by inhibitting thrombogenesis and the movement of macrophages in atherosclerosis plaques,thus minimizes the degree atherosclerosis and vessel intima hyperplasia.
