Objective To explore the imaging characteristics of pigmented villonodular synovitis(PVNS) of knee joint.Methods X-ray,CT and MR imaging features of PVNS of knee confirmed by operation,arthroscope and pathology were retrospectively analysed with literatures review.Results X-ray could only show the swelling of the joint cpasules,the destruction,defect and sclerosis of the bone under the articular surface.CT could show the soft tissue nodules in joint cavity projected from joint capsule.MRI was sensitive in showing the thickened synovium of joint and joint effusion,the soft tissue nodules and thickened synovium of joint were iso-or low signal intensity on T1WI,isointensity in one and low or slight hyperintensity in 4 on T2WI.Multiple haemosiderin deposit nodules were seen in the thickened synovium,which were low signal intensity on T1WI and T2WI in 4 cases,and the nodules were enhanced obviously on contrast-enhanced MR images.Conclusion MRI possesses obviously in diagnosis of PVNS of knee joint than X-ray and CT,which is helpful in diagnosis and differential diagnosis of PVNS of knee joint.

OBJECTIVE:To probe into a feasible work mode for special clinical pharmacist of hypertension.METHODS:Clinical pharmacists' works were summarized by considering the experience of clinical pharmacists and examples of pharmaceutical care in hypertension wards.RESULTS&CONCLUSIONS:Special pharmacists of hypertension should participate in clinical treatment team,check prescription every day and acquaintance with status quo of patients' medication so as to carry out pharmaceutical care suitability.It also should find out and resolve situation of ADR in time and master the characteristics of hypertension.

OBJECTIVE:To investigate the influence factors of plasma concentration of digoxin(SDC)and application of it in our hospital in order to promote rational use of digoxin. METHODS:445 cases treated with digoxin were collected from our hospital and plasma concentration of digoxin was detected. Multiple stepwise regressions were used to analyze current application of digoxin,relationship between SDC and factors including age,gender(Gen),departments(Dept),drug combination(Drug),serum creatinine concentration(SCR),dose. RESULTS:SDC was relation with age,gender(Gen),departments(Dept),drug combination(Drug),serum creatinine concentration(SCR),dose. CONCLUSION:There are many influence factors of SDC which are different among individual patients. In our survey,16.2% patients taking digoxin occurs adverse reactions. The most common adverse reaction is nausea and poor appetite. We should pay attention to arrhythmia caused by digoxin. The SDC of surgical inpatients were higher than that of medical inpatients(P

OBJECTIVE To learn the disinfection and sterilization for dental instruments and to provide scientific basis for related regulations according to the scheme made by Beijing Center for Disease Prevention and Control.METHODS To investigate some dental medical units by adopting investigation form,inquirement,checking about the record for disinfection equipment including such items as air,the surface of used material,hands,etc.RESULTS Altogether 39 dental medical units including 9 hospitals,21 joint clinics and 9 private medical units were investigated with 96.11%,88.79%,and 70.97% qualified rates,respectively.CONCLUSIONS In private dental units the qualified rate for disfection is poor,disinfection instruments are short,and the professionals knowledge related to disfection is little.As a result,strengthening monitoring and guidance to prevent hospital infection should be carried out at once.
