Objective Patients with previous failed scoliosis surgery were managed by revision surgery,the reasons, methods and results of revision surgery were evaluated and analyzed. Methods Thir-ty-six patients with previous failed scoliosis surgery underwent revision surgery between June 1996 and Au-gust 2002. There were 15 males and 21 females with an average age of 16.8 years. The patients had 1.57 operations on average (1 for 27 cases, 2 for 8 cases and 3 for 1 case). The reasons for revision surgery were failure of previous instrumentation (6 cases), deterioration of the deformity (18 cases), and unsatisfactory re-sults with previous surgery (12 cases). Thorough radiographic evaluations including plain X-ray, CT scan and MRI were taken for each patient pre-operatively. The preoperative average Cobb angle for scoliosis was 76.2?(52?-108?)?Of 36 patients, there were 11 with kyphosis and the preoperative average Cobb angle was 53?(36?-79?). The involved spines in the deformity were 10.1 on average (8-13 levels). The surgical proce-dures included removal of previous instrumentation in 21 cases, staged trans-thoracic anterior release in 5 cases with rigid curve, and osteotomy passing through articular joints and laminae on previous fusion mass in 18 cases. All patients underwent trans-pedicular fixation and fusion as well. The clinical and radiographic results were evaluated post-operatively. Results All patients underwent surgery safely. The average opera-tive time was 3.8 hours (2.8-5.1 h) and the average blood loss was 817 ml(630-1 800 ml). There were no serious complications such as neurological injury. The average correction was 48? (22?-64?, 56%) for scolio-sis, and 47? (17?-52?, 72%) for kyphosis respectively. All patients were followed up at least 12 months (12-76 months). There was no loss of correction found during follow up and all patients achieved solid fu-sion. At the last follow up, 33 patients (91.7%) were satisfied with the results of revision surgery. Conclusion Revision surgery for failed scoliosis surgery is challenging because of technical difficulties for the procedure and higher risk for neurological injury. Extreme caution must be taken for each patient during pre-operative examination and evaluation. If appropriate surgical procedure including staged anterior re-lease, posterior osteotomy and trans-pedicular fixation is properly selected according individual deformity, the satisfactory results can be achieved.

Over 3 000 pictures on five major parasites(schistosome,filaria,hookworm,leishmania and plas-modium)collected between 1950 and 1990 were edited and a searching system was established. The data can be used with a network-based version through a LAN system in the Institute. The adoption of Digital Computerized Management makes it possible for sharing resources in human parasitology.

To study the necessity and teaching evaluation of clinical medical teaching in dual language,we investigated the students of a five-year medical undergraduate in clinical medicine with a questionnaire.The attitude of medical students on necessity and teaching effect in bilingual teaching was surveyed and analyzed to provide the data and reference to effectively improve the bilingual teaching program.

Objective: During the five years period from 2006 to 2010, the Chinese government had increased the special funding for primary maternal and child health enterprise to analyze the total amount and constitution of the special funding respectively. Methods: From the perspective of special funding investment in the eastern, central and western regions with different levels of economic development, to perform the comparative analysis. Results and Conclusion:The government’s overall investment on maternal and child special funds is in increasing trend, the average per capita amount of special funds invested in west region is higher than the eastern and central region; in the aspect of investment constitution , the central government special funds for women and children is the main source, which accounts for more than 85% of total investment, the reducing and eliminating items in eastern and western regions and the inpatient childbirth subsidy items constitute the major component of special funding for primary maternal and child health in corresponding region. Based on the analysis of investment on the condition of primary maternal and child health , policy recommendations for further development of the cause of women and children are provided.

Objective To summarize the clinical and EEG characteristics of benign epilepsy of childhood with centro-temporal spikes(BECCT). Methods The clinical and EEG data of 78 children with BECCT were retrospectively analyzed. Results The onset age of this disease was 3 to 14 years, and 62 patients aged 5 to 10 years(62/78,80%). The seizures of 72 cases(72/78,92.3%)were associated with sleep. 63 cases(73/78,80.8%)were partial seizures, and 15 cases(15/78,19.2%) were generalized seizures. EEG demonstrated that there were sharp or spike waves of interior discharge in the centro-temporal area of one or two sides, 55.4% cases were positive in awake EEG, and 92% cases were positive in sleep EEG. 93.2% cases were responsive to antiepileptic drugs. Conclusion The characteristics of BECCT were as follows: partial epilepsy related to sleep, partial seizure types and sharp or spike waves of EEG in centro-temporal area. EEG sleep induction test could increase positive diagnostic rate of this disease, and the prognosis of this disease was fine. The early diagnosis is helpful for the patients' prognosis, and can alleviate psychological suffering of the patients and their families.

Objective To analyze the expression of HLJ1 in the tissues of hepatocellular carcinoma(HCC) and the correlation between its expression and clinical pathological characteristic.Methods HLJ1 mRNA expression level was determined in 32 HCC tissues and their associated noncancerous liver tissues by reverse transcription polymerase chain reaction(RT-PCR).The correlation of HLJ1 expression level with clinicopathologic variables was also analyzed.Results HLJ1 mRNA expression level was significantly lower in HCC than in associated noncancerous liver tissue [(1.18?0.82) vs.(1.92?1.15),P

Objective To introduce a new flap of cutaneous branches of posterior tibial artery on the part of superior medial malleolus to repair soft tissues defect on the feet and the ankles Methods From October 1997 to December 2001,a flap with the pedicle called cutaneous branches of posterior tibial artery on the part of superior medial malleolus were used to repair 11 cases which suffered skin and soft tissue defect on the feet and the ankles due to various trauma Results The flaps were survived completely on 10 cases and the flaps distal had about 2 cm necrosis on 1 case,the size of the flap ranged from 28 cn?11 cm to 8 cm?6 cm,all of the 11 cases were evaluated as satisfactory after 6 months to 2 years follow-up Conclusions The new procedure can repair mostly soft tissue defect on the foot and the ankle and does not sacrifice the major arteries. The flap is easy to be performed,and it is an safety and ideal method.
