BACKGROUND:Periprosthetic infection after artificial joint replacement is a disastrous complication for a patient. Currently, during treating for the periprosthetic infection, most of patients need two-stage revision, which bring about enormous physical and psychological pain for patients, and a heavy burden for the families and society. To make matters worse, the effect is not very perfect, and some of these cases require multi-stage revision, even amputation. OBJECTIVE:To investigate the therapeutic effect of vacuum sealing drainage combined with iodophor douche for the infection after artificial joint replacement. METHODS:Nine cases (six knees and three hips) of infection after artificial joint replacement were col ected, with an average age of 63.4 years. Infection occurred at 7 days-14 months, and a median time of 1 month after replacement. Al patients suffered from purulent or purulent blood secretion. Fistula formed in two cases and incision and drainage sites were not healed in one case. According to the bacterial culture results, above symptoms were accorded with clinical diagnosis of prosthesis infection. The prosthesis was remained for debridement. Vacuum sealing drainage was performed. Iodophor douche (30-50 mL) was conducted every day. The drainage tube at proximal end was occluded for 30 minutes, and then vacuum sealing drainage was performed. Al patients were regularly fol owed up to assess the therapeutic effects of vacuum sealing drainage combined with prosthesis infection after replacement. RESULTS AND CONCLUSION:(1) Except that one case was stil in treatment, one case was dead, and one case of tumor prosthesis was failure and final y amputated, the remaining six patients were healed. (2) The time of vacuum sealing drainage and iodophor douche was 10 to 84 days, with the median time of 57 days. No adverse reactions or complications occurred. Al healed patients were fol owed up for 12-60 months, without recurrence. (3) These results indicated that vacuum sealing drainage combined with iodophor douche retained the prosthesis to the greatest degree, is simple, safe, and effective for the infection after artificial joint replacement, needs a low cost, and is a kind of therapy for prosthesis infection after artificial joint replacement.

Objective To explore the surgical treatment of ankle fracture.Methods 326 cases with ankle joint fracture in our hospital treated by surgical treatment were followed up.There were 182 males and 43 females,aged from 7 ~ 75 years.The patients with medial malleolus fracture were cut through postero-medial process,and the lagged screw,absorbed screw,or tension band wire were used.Patients with bimalleolus and trimalleolus fracture were cut through medial and lateral two incision.When the fracture line of the fibula is high,the triangular needle,kirschner wire,plate and the screw,remember alloy were used,when the fracture line of the fibula was high,1 ~ 2 cortical or cancellous bone lagged screw were used.The patients with diastasis of inferior tibiofibular syndesmosis were cut through lateral process,1 lagged screw was used through 3 layer cortical bone.After the operation,the plaster or brace was used according to the stability of the fracture,then systemic functional exercises.Results All the patients were followed up from 4 ~ 120 months,according to the ankle-hind foot score of American Orthopedic Foot and Ankle Society Score(AOFAS),their clinical treatment results were assessed.In 225 cases,excellent and good rate was 86.7%.Connclusion Proper approach,anatomy reduction,articular surface recovery to smooth,stable internal fixation,necessary external fixation and systemic rehabilitation were the key aspects to the surgical treatment.Good result of most of the patients with fracture of the ankle joint can be obtained.

[Objective] To disuse the traumatic mechanism,clinical feature and treatment of the occult osteochondral avulsion of the posterior ankle joint.[Method]The data of 6 patients had been reviewed.From 2003.9 to 2006.6,6 patients had been treated,including 4 male and 2 female,with the average ages of 31.7 years(27~38 years).They all had injury history of their ankle but no fracture or dislocation had been found in X-ray film immediatey after the trauma.Four of them had been treated by plastic cast fixation of their ankle for 3 weeks,2 received treatment without fixation,but all the patients suffered pain and tenderness in the medial-posterior or the lateral-posterior of the ankle with leg or/and food radiation.The symptoms were persistent even when they were rest.The diagnosis of osteochondrl avulsion fracture had not been made until they were admitted in 4 mouth to 1 year after the injury.The fractured bone debris were showed by X-ray film and CT scan.All patients had been treated by operation of ablating the fractured fragment.[Result]All symptoms in the ankle had disappeared 2~3 days after the operation and no recurrence during 6 mouth to 2 years follow up.[Conclusion]It shoud be attaching importance to the occult osteochondral avulsion in early time after ankle injury,and when the diagnosis is made,operation is the appropriate treatment.

OBJECTIVE:To establish a RP-HPLC method to simultaneously determine the contents of piperacillin and taz_obactam METHODS:Using ? Bondapak C18 column as fixed phase,a mixture of methanol and purified water(34 5∶65 5)as mobile phase,and caffeine as internal standard,detecting wavelength:220nm,flow rate:1 0ml/min RESULTS:The linear rangs of piperacillin and tazobactam were 40~200?g/ml and 5 0~25 0?g/ml respectively The average recovery and RSD (n=5) were (100 2?0 61)% for piperacillin and (99 03?0 90)% for tazobactam CONCLUSION:This method is rapid,simple and accurate

A spectrophotometric method for the determination of calcium in milk, hair and urine was developed using metal complezing dye orthocresolphth-alein complexone(OCPC).The organic matter in the tested sample was destroyed by digestion. An aliquot of the digested solution was mixed with color developing reagent, alkaline OCPC, cantaining 8-quinolinol to suppress interference such as magnesium, and the absorbance was measured at 570 nm.The coefficients of variation were 0.87, 3.6 and 1.2% for milk, hair and urine samples; and the analytical recoveries of calcium from milk, hair and urine averaged 100.4, 101.0 and 98.5% respectively. The calcium content of milk and hair determined by this method was closely correlated with that of the ICP-AES method (r =0.994, p
