Objective To evaluated the surgical techniques and results of open reduction and internal fixation performed for ankle fracture. Methods Eighty-two patients with ankle fracture were treated with open reduction and internal fixation from March 1995 to June 1999. Fifty-eight patients with complete clinical data were analyzed. The patient group consisted of 36 males and 22 females. According to Weber-AO classification, the group was made up of 30 Weber B cases,28 Weber C cases. All patients were evaluated with modified Baird and Jackson scoring system. The relationship between final result and fracture pattern, fixation methods, the time of exercise initiation after operation were analyzed respectively. Results The followed-up period varied from 2 months to 52 months, with an average of 17 months. The number of patients whose results was excellent, good, fair and poor was respectively 31, 18, 6 and 3. The total percentage of good to excellent clinical results was 84.5%. Fifty-four ankles were completely pain free and the remainders had only slight pain after long time walking. Conclusion Operative treatment may provide satisfactory fracture reduction and clinical results for ankle fracture. Correct fracture pattern estimation and proper internal fixation is of importance to achieve and maitain reduction, and then, to gain better long term results.

Objective: To investigate the therapeutic efficacy and mechanisms of ?-sodium aeacine in treating chest trauma.Methods: One hundred and sixty patients with chest trauma were randomly divided into two groups: the control group and the study group.The control group was treated by conventional method,while in addition to the conventional treatment,the study group was also treated with ?-sodium aeacine,10 mg of ?-sodium aeacine in 250 ml 10% glucose solution for intravenous drip,30 to 40 drops/min,twice a day for 10 days(one therapeutic course).Results: The effective and total effective rates of the study group were significantly higher than those of the control group(the effective rate(62.5% vs.22.5%) and the total effective rate(97.5% vs.66.3%),both P

Objective:To investigate the preemptive analgesic effect of flurbiprofen on inflammatory cytokine in patients undergoing cerebral operation.Methods:Forty ASA Ⅰ-Ⅱpatients undergoing cerebral surgery were randomly divided into control group(group C,n=20)and flurbiprofen group(group F,n=20).Flurbipmfen of 10 mL was given intravenously 15 min before skin incision.The values of VAS scores were recorded at 2 h,24 h and 48 h after operation.Blood samples were taken for determination of serum levels of TNF-α,IL-6 and IL-10 immediately before induction of anesthesia(T1,baseline),at 2 h of operation (T2),immediately after the end of operation (T3) and 24 h after operation (T4).The parameters of anaesthesia time,hemorrhage volume,urine volume,transfusion volume and the dosage of remifentanil and propofol were recorded during the period of anaesthesia.Results:The VAS score was lower in group F than that in group C at 2 h and 24 h after operation (P＜0.05),but there was no difference at 48 h after operation between the two groups(P＞0.05).The dosages of remifentanil and propofol were lower during anaesthesia in group F than that in group C(P＜0.05).Compared with T1,TNF-α was significantly increased at T2 and T3 in both groups,and the peak value at T2 (P＜0.05).TNF-α was decreased at T2-T4 in group F than that in group C(P＜0.05).Compared with T1,the levels of IL-6 and IL-10 were significantly increased at T2-T4 in both groups,and the peak value at T3(P＜O.05).The value of IL-6 was decreased and the value of IL-10 was increased at T2-T4 in group F than those in group C (P＜0.05).Conclusion:Flurbiprofen was suitable as a preemptive analgesia and could suppress stress reaction of inflammatory in neurosurgery.

Objective To evaluate clinical application of arterial embolotherapy on hyperthyroidism. Methods 11 patients with hyperthyroidism were performed with thyroid superior and inferior arterial super selective arteriography and interventional embolization by polyvinyl alcohol(PVA),gelfoam particles and wool gianturco coil. Results The procedures were succeeded in 11 patients. After the embolotherapy , the thyroid function gradually returned to normal level in 10 patients. The symptom was not controlled satisfactorily in 1 patient, who underwent the right thyroid inferior arteries superselective arteriography and interventional embolization, and then the thyroid function gradually returned to normal level. No serious complications occurred in all patients. Conclusions Arterial embolotherapy is a safe, simple,symptomless, reliable and very effective for treatment of hyperthroidism.

Objective To explore the clinical features and diagnosis of primary immunodeifciency disease caused byTyk2 gene mutations.Methods Clinical data from the ifrst case in China diagnosed of primary immunodeifciency disease caused by Tyk2 gene mutation were retrospectively analyzed, and related literature was reviewed.Results One year and 3 month old boy suffered with repeated pulmonary infection, chronic otitis media, intractable eczema like rash, repeated skin abscess, HSV infection, intracellular bacterial infection, and remarkedly increased total IgE. It was detected that compound heterozygous mutations of c.2269C>G in No. 16 exon and c.149delC in No. 3 exon inTyk2 gene. Literature searching found other 8 cases (5 males and 3 females) of immune deifciency patients caused byTyk2 gene defects, all of which hadTyk2 gene homozygous mutations and presented with repeated infection of paranasal sinus and lung. In the 8 cases 6 cases were combined with mycobacterium tuverculosis infection, 4 cases had repeated virus infection, 4 cases had meningonecephalitis, 3 cases had intractable eczema like rash, 2 cases had salmonella enteritis, 1 case had remarkedly increased total IgE, one case had elevated eosinophils, 5 cases were born in intermarriage family and 1 case died of meningitis caused by unknown etiology.Conclusions When patients have repeated paranasal sinus infection and lung infection, combined with intracellular bacterial infection (including mycobacterium tuberculosis infection), and repeated virus infection or intractable eczema like rash, with or without increased total IgE, immunodeifciency disease caused by Tyk2 gene defection should be considered. Gene sequence analysis can assist in early diagnosis.

Objective To investigate the effects of ketamine on anoxia-reoxygenation(A/R)induced glutamate release from cerebral cortex neurons.Methods Primary cultured neurons obtained from cerebral cortex of fetal Wistar rats(16-18 d)were randomly divided into 3 groups:Ⅰcontrol group;ⅡA/R group andⅢketamine pretreatment+I/R group.The control group was not subjected to A/R while A/R group was exposed to anoxic air(95% N_2+5% CO_2)for 5 h followed by 24 h reoxygenation.In groupⅢdifferent doses of ketamine were added to the culture media before anoxia and the final ketamine concentrations were 1,20 and 100?mol?L~(-1) respectively.The extracellular glutamate concentration was detected at the end of 24 h reoxygenation.Results The extracellular glutamate concentration was significantly higher after 24 h reoxygenation in A/R group than in control group.Ketamine 20 and 100?mol?L~(-1) significantly inhibited glutamate release from the neurons induced by A/R in a dose-dependent manner.Conclusion Ketamine can inhibit glutamate release from neurons induced by A/R in a dose-dependent manner.

OBJECTIVE To get knowledge of the drugs resistance change of Pseudomonas aeruginosa in intensive care unit (ICU) from 2001 to 2006, so as to offer the first-hand information to the clinical preventive and therapeutic countermeasures. METHODS The P. aeruginosa antimicrobial susceptibility tests to 15 commonly used antibiotics were performed from 2001 to 2006. RESULTS The most frequent isolates were P. aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii in 2001-2004. Staphylococcus aureus was more than A. baumannii in 2006, and became the major isolated pathogen in the sputum of the ICU patients. The multi-resistant P. aeruginosa increased yearly, and drugs susceptibility to carbapenem had decreased sharply in the past 6 years. CONCLUSIONS It was showed that P. aeruginosa is the major pathogen in the ICU, and the pathogens show the high drug resistance. Doctors should pay more attention to analyze the bacterial resistance profile in order to decrease the incidence of drug resistance and use the antibiotics properly.
