Objective To evaluate mid-term clinical and radiographic outcomes associated with cementless total hip arthroplasty(THA) in a consecutive series of patients with osteonecrosis of the femoral head. Methods This study examined the mid-term (equal to or more than 5 years) results of THA. From January 1998 to March 2001, a series of 71 patients (80 hips) who had undergone THA with cementless components in our hospital were involved in this study. All patients were evaluated both clinically and radiographically. Clinical outcomes were evaluated according to Harris evaluation score. Components migration, bone changes around the implant, the polyethylene wear rate and direction of the acetabular polyethylene wear were measured radiologically. Kaplan-Meier analysis was performed to evaluate the survival of the femoral and acetabulum components. End point was radiographical loosening or revision of the acetabular component, and revision of the femoral component for any reason. Results 62 hips in 54 patients were followed up at least 5 years. The mean Harris hip score improved from preoperation (44.0?8.4) points to (92.4?5.7) points at the time of final follow-up. No component was seen to be loose radiographically or had been revised because of any reason at the time of final follow-up. Only one focal area of pelvic osteolysis in one patient and twelve small focal areas of femoral osteolysis in another patient were identified. The mean linear wear rate was (0.125?0.074) mm/year. When loosening was used as the end point for failure, the survival rate of the acetabular and femoral components was 1.0 (95% confidence interval, 0.98 to 1.00) in both groups. Conclusion Cementless THA in patients with osteonecrosis of the hip had a satisfactory clinical and radiographic outcome at a minimum of five years follow-up. Because polyethylene wear and osteolysis can not avoided, radiographical follow-up for cementless components is very important.

OBJECTIVE:To improve the accuracy of the Cetirizine hydrochloride syrup pediatric dose for children. METH-ODS:The dosage of Cetirizine hydrochloride syrup for children with chronic urticaria was accurately measured and compared with before and after pharmacists’intervention. RESULTS:The dosage before and after pharmacists’intervention was significantly high-er than prescribed dosage,the dosage after intervention was lower than before intervention,the differences were statistically signifi-cant(P<0.05). CONCLUSIONS:It is commonly existed that the dosage to children is higher than the prescribed dosage. It is sug-gested that doctors should strictly follow the printed label to make a prescription,pharmacists should strengthen the guidance and in-tervention on medication,and pharmaceutical manufacturers can manufacture suitable Cetirizine hydrochloride preparations special-ly for children to improve drug compliance and dosage accuracy.

To determine the regulatory effect of ? opioid receptor stimulation on ? adrenoceptor signaling and its underlying mechanism, single ventricular myocytes were isolated from the heart of rat subjected to chronic hypoxia for 4 weeks. The electrically induced [Ca 2+ ] i transient were measured using a spectrofluorometric method. RT PCR was used to determine the mRNA of ? opioid receptor, and Western blot was used to determine the Gi and Gs protein. ? adrenoceptor stimulation with isoproterenol increased the amplitude of the electrically induced [Ca 2+ ] i transient in myocytes of normoxic rats. U50488H, a selective ? opioid receptor agonist, significantly inhibited the effect of isoproterenol. In the heart of chronically hypoxic rats, the inhibition of U50488H was blunted. RT PCR revealed no significant change in mRNA of ? opioid receptor. Western blot showed no change in Gi protein. While biologically active Gs small protein decreased significantly. The results indicate that the negative modulation of ? opioid receptor on ? adrenoceptor is attenuated in the heart of chronically hypoxic rat. The decrease in Gs protein may be partially responsible for the attenuation.

Background The application of femtosecond laser in the corneal refractive surgery has made great progression recent years,but the morphology characteristic of corneal stroma surface after making-flap of femtosecond laser is closely concerned.Objective This study was to analyze the influence of photodisrnption of femtosecond laser on the corneal stroma surface and to investigate the effect of different laser pulse energy on the sudace ultrastructure of corneal stroma.Methods Corneal flaps were made with Visu Max femtosecond laser in 16 fresh porcine eyes with the pulse energy 125 nJ,155 nJ and 195 nJ respectively,and Moria-M2 microkeratome was used as control.Scanning electron microscopy (S-3400N Hitachi High-Technologies Corp) was used to observe and compare the ultrastructural characteristic of corneal stroma bed surface after making of corneal flap.Results The corneal strnma was evaporated and created a smooth surface when photodisrnption happened in the femtosecond laser group.Residual tissue bridges could been exhibited among the cavitation bubbles under the scanning electron microscope.Corneal strnma surface was smooth in the 125 nJ pulse energy group,but some tissue bridges still were visible.In the 155 nJ pulse energy group,much more smooth surface was seen without tissue bridges and mechanical damages on the corneal surface.However,the surface quality was worse and many tissue bridges and grooves existed in the 195 nJ pulse energy group.In addition,different sizes of slots caused by big cavitation bubbles were visible with the round and oval shape.The edges were regular and sharp with small damage zone after cutting with femtoseeond laser.However,many elevated fibril tissues could be seen on the corneal surface after making of flap with microkeratome.Many crimp and irregularity tissues were found on the surface.Blunt surface and indentations appeared in the cutting edge.Conclusions The mierostrueture of corneal stroma surface is more smoother after making of corneal flap with fentosecond laser in comparison with microkeratome.Pulse energy of 155 nJ is preferably during the making-flap with femtosecond laser.
