RET gene is an important oncogene,which is closely associated with the development of various types of human tumors. The mainly mechanisms of RET gene associated tumor are mutation and over-expression of wild type. Activated RET protein participates in the proliferation,apoptosis,metastasis through some signal pathways and influences the tumorigenesis and development.

[Objective]To investigate the clinical effect of saddle-shaped condylar plate in treating the fracture of the femoral intercondylar and supracondylar.[Method]Thirty-two cases with the fracture of the femoral intercondylar and sapracondylar,who were selected randomly were fixed by saddle-shaped condylar plates after reduction,of which 8 cases of patellar fractures accompanied with ipsilateral fracture of the femoral condylar.[Result]All cases were completely healed during the follow-up study of 4 months to 2 years,all cases achieved bone union in 5～9 months.[Conclusion]The design of the plate conforms to the principle of biomechanics and is good for the heal of the fracture.The saddle-shaped structure makes the plate and the cannular bone tangent as fixing so it can reduce the putrescence of the bone which is caused by pressure;The arch-bridge-shaped juncture and the mechanical bolts which are fixed across can strengthen the power of anti-bending and anti-rotation of the broken ends of the fractured bone.The stability of the fixation enables the patient do the functional exercise after the operation as soon as possible.It has definite clinical value and is worth of popularization.

Objective To investigate the changes of the activity and the distribution of the rat cardiac calcineurin (CaN) which is the signalling molecule of the hypertrophy induced by the external aldosterone(Ald), and to detect the mechanism of the regulation of CaN. Methods 21 male wister rats were randomly divided into 3 groups: group Ald(7 rats), treated with Ald 18?g/d, peritoneal injection (i p) for 4 weeks; group spironolactone (spiron) (7 rats), treated with Ald and with spiron 20mg?kg -1 ?d -1 oral for 4 weeks; and group control (7 rats). The plasma concentrations of Ald, angiotensin Ⅱ(Ang Ⅱ)and endothelin(ET), blood levels of NO, the tissue activity of the CaN and distribution of CaN A? in the myocardium of the left ventricle, were detected in the rats by the radioimmunoassay , by the nitrate assay, by the chromophoric assay and by the immunohistochemistry, respectively. Results The concentration of the plasma Ald increased by 1 62 times, the blood NO - 3 concentration was deceased, the ratio of Ald over NO - 3( Ald/ NO - 3) increased by 2 95 times, and the cardiac tissue levels of CaN activity was were 1 47 times higher, in the rats treated with ald than in the normotensive rats. CaN A? distributed over cardiac cytoplasm, and the positive dyeing of the local CaN A? in the cytoplasm was thick near the cell membrane in the rats treated with Ald. The treatment with spiron could decreased the blood levels of the AngII?Ald/ NO - 3?ET/NO - 3?AngII/ NO - 3 and the tissue activity of myocardial CaN, positive dyeing of the local CaN A? in the cytoplasm, and increased blood NO - 3 concentration. Conclusion The aldosterone may be the main stimuli factor which can damage the balance of the blood active factors, and then make a novel cardiac hypertrophic signalling molecule calcineurin activated and redistributed in the cytoplasm of the rat left ventricular myocardium

0.05).) Conclusions Coxsackie virus is the most common pathogen in patients with viral meningitis in Chaoshan district, and the organization of disease prevention and scientific research and clinical medical should attach importance to it.

BACKGROUND: Patient subjective satisfaction is of great significance for the clinical use of implant denture.OBJECTIVE: To investigate the patient satisfaction with single or bridge crown for repair of consecutive missing posterior teeth in the maxilla.METHODS: We selected 203 patients with consecutive missing of maxillary first and second molar teeth, who had received single (n=99) or bridge (n=104) crown for implant restoration 1 year ago. All patients were surveyed with a subjective satisfaction questionnaire and visual analogue scale.RESULTS AND CONCLUSION: There was no significant difference in sex and age (35-64 years) between the two groups. Food impaction ratio and crown off ratio were higher in the bridge crown group than the single crown group.Noticeably, most patients did not have the habit of using dental floss. The overall satisfaction scores were 88.96% in the single crown group and 85.32% in the bridge crown group, respectively. Four indexes with less than 80 scores in the two groups were that I dare to use the implant teeth to bite hard food, my implant teeth are easily cleaned, it takes me less time to clean my implant teeth than natural teeth, and I think the dental implant price is acceptable. Results from the analysis of variance showed that food impaction influenced chewing effect (P=0.047), made the use of dental floss difficult (P=0.031), made patients discomfort (P=0.038), and the use of dental floss could enhance the cleaning effect on dental implant (P=0.019), and largely reduced brushing bleeding (P=0.029). In conclusion, patients with missing maxillary posterior teeth can obtain higher satisfaction after single crown or bridge crown repair. However, food impaction and crown off become more serious after repair with bridge crown, while the repair with single crown exhibits better performance.

Aerospace nutrition and food hygiene is a subject elucidating the effect of aerospace envi-ronment on nutrition and food hygiene which is closely related to health of flight personnel. The teaching work should be in the aim of raising battle effectiveness and enforcing the primary professional capability of students. The most required theory and techniques in both peacetime and wartime was the priority of teach-ing fulfilling mainly through practical or in-site learning. The examination was composed of test paper, ex-periments and health propaganda. The teaching evaluation relied on feed-back of the army on which the teaching plan was revised. Survey in three straight years indicated the exploration enhanced teaching quality significantly.

BACKGROUND:The incidence of femoral head necrosis after internalfixation in femoral neck fracture is at highlevel, but the risk factors are stil under discussion. OBJECTIVE:To retrospectively propose and analyze the relative risk factors of femoral head necrosis after internal fixationwithfemoral neck fracture in patients younger than60years old. METHODS:Data from199 patients with femoral neck fractures,younger than60years,undergoingclosed reduction and internal fixation were analyzed retrospectively.Seven factors including age, sex, body mass index, Garden classification, fracture seasons, reduction quality and weight-bearing time after internal fixation were statisticalyanalyzedto evaluate their correlation with femoral head necrosis. RESULTS AND CONCLUSION:The incidence of femoral head necrosis was 13.1%amongthe199 cases. Body mass index, Garden classification, fracture seasons, reduction quality were significantly associated with femoral head necrosis. The age, sex and weight-bearing time wereinsignificantly associated with femoral head necrosis. In multivariate logistic regression analysis, Garden classification, reduction quality and fracture seasons (winterversussummer) hadoverteffectson development of femoral head necrosis. These results suggest that Garden classification and reduction quality make an important effect on the healing of femoral neck fracture. In addition, fracture in winter may be the risk factor of the femoral head necrosis after internal fixation in femoral neck fracture.

Septic arthritis of the sternoclavicular joint(SCJ) is a rare condition and accounts for 0.5％-1.0％ of septic arthritis.SCJ infections often require surgical intervention.Diabetes mellitus,rheumatoid arthritis,intravenous drug use,intraarticular injection and immunosuppressive disorders are predisposing factors.Staphylococcus aureus and Pseudomonas aeruginosa are the most common bacteriologies.Early diagnosis of SCJ infection requires a high index of suspicion and a confirmatory CT or MRI scan.The characteristic imaging features include intramedullary and soft tissue gas,sequestra,soft tissue swelling and destruction or widening of joint space.Management strategies have ranged from conservative antibiotic therapy to en-bloc resection of the sternoclavicular joint with or without ipsilateral pectoralis major muscle transposition.The shoulder function in most patients were well preserved.
