OBJECTIVE:To explore the lessons of plate fixation failure and the experiences of retreatment. METHODS:Computer-based online search of CNKl,CBM,VlP,Wiley,Elsevier,Springer and Kluwer databases were performed with of "plate,failure,breakage" to retrieve literature (1999/2008). RESULTS:The risks of plate fixation failure were hidden in the whole procedure of fracture treatment and rehabilitation course. The integrated evaluation and composite methods should be used in retreatment. CONCLUSION:Strict interal fixation indication,resonable internal/external fixation methods should be emphasized on fracure treatment. Precise principles understanding,perfect operative skills,biological osteosynthesis methods should be emphasized on plate implanting. A step-by-step rehabilitation course and regular follow-up should be emphasized on post-operation. A bone graft plus vascularized periosteal flap transplanting method would greatly increase the bone union rate in retreatment.

ObjectiveTo analyze the expression and significance of Ets－ 1 (E26 transformation－specific) in chondrosareoma and osteochondroma of the jaws.MethodsEts－ 1 expression was de-tected by immunohistochemistry in 20 cases of chondrosarcoma and 8 cases of osteochondroma of thejaws.Results12 of the 20 cases of chondrosarcoma (t50%) showed an Ets－ 1 positive reastion. Thepositive rates of grade Ⅱ and grade Ⅲ were significantly higher than that of grade Ⅰ ( P < 0.05 ). Re-current cases showed a higher Ets － 1 positive rate than primary ones ( P < 0.05 ). Ets － 1 was presentin 12.5 % (1/8) osteochondroma. The positive rate was significantly different between chondrosarcomaand osteochondrorna ( P < 0.05 ).ConclusionThe results indicate that Ets－ 1 is overexpressed inchondrosarcoma of the jaws and correlated with its pathological grade and recurrence.

Objective To research community residents TCM constitution and impaired glucose regulation and diabetes,for providing the basis of the community carrying out the adjustment of biased constitution,prevention and treatment of impaired glucose regulation and diabetes.Methods The cross-sectional survey was conducted in Hualin Street,Liwan District,Guangzhou,and 1882 cases of elderly residents over the age of 45 were surveyed on their TCM constitution and blood sugar.According to the Chinese constitution scale survey all cases were divided into gentleness type,yang-deficiency type,qi-deficiency type,dampness-heat type,phlegm-dampness type,yin-deficiency type,qi-depression type,blood-stasis type,and special diathesis type.Divided according to the level of their blood glucose,all cases were classified to normal blood glucose,impaired glucose regulation and diabetes.Logistic regression analysis was conducted to study the relation between TCM constitution and impaired glucose regulation and diabetes mellitus.Results The ratio of phlegm-dampness type in glucose regulation damage and diabetes was much higher than normal blood sugar,the value was 10.07％,19.10％ and 4.98％ respectively.The ratio ofyin deficiency type in diabetes was higher than normal blood sugar,the value was 16.85％and 12.27％,respectively.Compared with gentleness type,a logistic regression analysis model showed that the risk of impaired glucose regulation of phlegm (OR 2.08; 95％CI 1.80 to 2.36) and diabetes (OR 4.39; 95％CI 3.56 to the risk of 5.42) were significantly increased in phlegm-dampness type,and the risk of diabetes (OR 1.62; 95％CI 1.31 to 1.99) was significantly increased in yin deficiency type.Excluded the influence of gender,age,eating habits,the second models showed similar results to the first model,with the phlegm of impaired glucose regulation (OR 1.95,95％CI 1.68 to 2.27),diabetes (OR 4.01,95％CI 3.22 to 5.00),yin deficiency diabetes (OR 1.55,95％CI 1.25 to 1.93) all similar to the first model.Conclusion Phlegm-dampness type and yin-deficiency type are the main TCM constitutions that influencing glucose regulation impairment and diabetes.

Objective To investigate the relevant risk factors for,clinical manifestation and treatment responses of symmetric acral keratoderma in 9 patients.Methods Clinical data were collected from 9 outpatients with symmetric acral keratoderma.Skin lesions were photographed,tissue specimens were obtained from the lesions and subjected to fungal and histopathological examinations.The patients were given topical treatment.Results There were 8 males and 1 female in these patients with an average age of 28.2 years and age at onset of 24.6 years.The disease duration varied from 2 months to 16 years.The lesions were predominantly distributed on the dorsum of both hands and wrists symmetrically and circularly.Ankles were the third popular site involved.Generally,the lesions were aggravated in summer,spontaneously cured in winter.Most of the patients had a history of occupational contact with plastics or rubber.Some patients suffered from ichthyosis vulgaris.Microscopic examination for fungal element was negative.Histopathology revealed epidermal hyperkeratosis,acanthosis and mild papillomatosis.The urea and Vitamin E cream mixed with clobetasol propionate cream at a ratio of 1 ∶ 1 proved to be effective.Conclusions Ichthyosis vulgaris may be a risk factor for symmetric acral keratoderma.The whitening of lesions after short exposure to water may be a kind of physical phenomenon with the involvement of water and air.Topical steroids may serve as the first-line treatment choice for symmetric acral keratoderma.

Objective To investigate the multi-organ lesions and the occurrence of coronary aneurysms in children with Kawasaki disease(KD).Methods 92 pediatric inpatients with KD were enrolled and studied.The organs involved and coronary aneurysms(CAA)were determined by checking blood routine,urine routine,stool routine,chest X-ray,electrokardiogram,liver function,echocardiogram,and clinical manifestation.Results The incidence of various organs involved in 92 patients with KD:heart 71.7%;lung 37.0%;liver 34.8%;brain 12.0%;kidney 18.5%;gastrointestinal tract 15.2%;spleen 2.2%;gallbladder 1.1%;joints 9.8%.In addition,the rate of two organs involved simultaneously was 40.2%,three and more 34.8%.The incidence of CAA in brain lesion,joints lesion and pericardial effusion complications of KD was 45.5%,44.4%,and 41.7%,respectively.Conclusions The data shows that the incidence of heart involvement in the sick-children with KD is highest,and other organs,such as lung,liver,kidney,gastrointestinal tract,brain and joints are involved in turn.The incidence of 2 and more organs involved simultaneously amounts to75.0%.CAA is the most serious complication of KD.Our study suggests that the incidence of CAA is obviously high in these lesions of brain,joints and pericardial effusion involvement in KD.

Objective To study the biological effects of nucleic transcript factor NF-?B/RelB gene silencing on bone marrow derived dendritic cells(BMDCs).Methods For constructing a new type of DCs,RNAi RelB DC,mouse BMDCs were cultured through IL-4 and GM-CSF cytokine inducing system and were purified with CD11c positive immunomicrobeads by flow cytometer,and RelB gene was silenced with PCR expression cassettes.The RelB RNA interference effect in DCs was proved at both mRNA and protein levels.The biological characteristics of RNAi RelB DCs were investigated by means of cell morphology,cell surface markers and mixed lymphocyte reaction ability.The cell microstructure was observed using scanning electron microscopy and transmission electron microscopy.The cell surface markers,such as MHC-Ⅱ,CD86 and CD40,were detected by flow cytometer.The mixed lymphocyte reaction ability,as well as the ability of DCs in stimulating allogeneic T cells proliferation,was detected by 3H-TdR incorporation method.Results RNAi RelB DCs seemed to have fewer and shorter spikes and many folds under scanning electron microscopy.Many phagocytic vacuoles were observed in the cytoplasm under transmission electron microscopy.DCs surface molecules,MHC-Ⅱ,CD86 and CD40,were expressed at a relatively lower level compared with the control DCs.This RNAi RelB DCs also showed weak allogeneic T cells stimulating ability in vitro in MLR.Conclusion The dendritic cells derived from bone marrow are characterized the biological features and immunological function of immature DC with silencing of RelB gene.This kind of RNAi RelB DCs may be used to induce immunotolerance as a novel tolerogenic DCs.

Thyroid-like papillary adenocarcinoma is an extremely rare neoplasm in the nasopharynx. We present a case with a pedunculated tumor in the nasopharyngeal vault. Complete tumor resection via nasal endoscopy was performed subsequently. Postoperative histopathological examinations and immunohistochemical studies confirmed the diagnosis of thyroid-like papillary adenocarcinoma. This rare neoplasm demonstrated a distinct etiology and nature from typical nasopharyngeal carcinomas and should be managed mainly by surgical resection.
