Objective To evaluate the efficacy of radiosynovectomy with 32P colloid in haemophilic synovitis of adolescents. MethodsRadiosynovectomy with 32P colloid was primary performed on 26 male haemophilic patients(26 joints),whose average age was 16 years(11 to 21 years).The average dose of 32P colloid was 2.1 mCi(1.0 to 3.0 mCi). Results After 6-month interval,haemarthrosis was reduced by no less than 30% in 23 patients,with a total efficacy of 88.5%.The mean frequency of haemarthrosis was reduced from 1.9 per month of presynovectomy to 0.3 per month of postsynovectomy(P

Objective To evaluate the localization of mitral valvular(MV)prolapse by transthoracic echocardiography(TTE),transesophageal echocardiography(TEE)and explore the interrelationship between the different subregions of MV prolapse and mitral regurgitation(MR).Methods Total of thirtythree patients with MV prolapse and more than moderate MR were included.TEE was used to further judge the location of scallop lesions and the result of both TTE and TEE were compared with the surgical findings respectively.The relationship between the different subregions of MV prolapse and MR was analyzed.Results Compared with the surgery findings,the accuracy rate of TTE and TEE in diagnosis of MV prolapse was 100％ qualitatively,80％ for TTE and 94％ for TEE in localizing the diseased region with the anterior and posterior MV,the result of TEE was significantly different from TTE(P＜0.05).MR level was related to the location of MV prolapse.Conclusions Compared with the TTE,TEE had more advantages in localizing the position of the MV prolapse.Mitral regurgitation is related to the location of MV prolapse.

0.05).At different time points after ischemia-reperfusion,the expression of cytochrome C and activation of caspase-3 were lower in the transgen mice than that in the wild type rats.Conclusions Under standard condition,overexpression of bcl-xl could significantly reduce the infarct area and improve neurological function in transgene mice than those in the wild type rats.The effect of overexpression of bcl-xl might be realized through inhibiting the apoptosis of neuron,and the mechanism might be that the overexpression of bcl-xl inhibit the release of cytochrome C and the activation of caspase-3.

Objective:To investigate the protective effect of intensity-modulated radiotherapy (IMRT) on salivary gland function in nasopharyngeal carcinoma (NPC) patients. Methods:In total, 101 NPC patients who were admitted from March 2010 to November 2012 were enrolled in this study. The parotid gland, the submandibular gland, and the oral cavity were sketched as the organs at risk (OARs). The patients were treated with IMRT and were evaluated through a face-to-face interview using a dry mouth assessment ques-tionnaire during the follow-up visits at 3, 6, 12, 18, and 24 months. The dose volume histogram of the salivary gland of the patients was also considered. Results:The mean doses (MDs) in the parotid gland were 37.4 and 33.8 Gy in the affected and uninjured sides, respec-tively. Meanwhile, the MDs in the submandibular glands were 51.6 and 45.7 Gy in the affected and uninjured sides, respectively. The MD of the oral cavity was 38.2 Gy. At 6 months after the treatment, the symptom of xerostomia was significantly improved in 77.2%of the patients (78/101). One year later, only less than 5%of the patients complained of having G3 or higher-grade xerostomia. Conclu-sion:With time, xerostomia significantly improved after the radiotherapy. At least one of the V30 to V35 of the parotid gland was≤50.0%, whereas at least one of the V40 to V45 of the submandibular glands was≤66.7%~50.0%. The MD for the oral cavity should be<40 Gy to effectively protect salivary gland function.

Objective To evaluate the effectiveness of the comprehensive intervention program of Xinjiang and to analyze the main problems to provide references for the adjusting on the intervention strategies in future work.Methods Based upon the combination of reviewing literatures,field investigations and questionnaires,an overall evaluation was made on the effectiveness of the program,supportive policies and intervention measures,etc.Results Some progressions had been achieved in the early days.However,in recent years,the negligence of the work and failed coordination between the related governments,and unbenefitting policies for iodinated salt,were the main obstacles for the progress.Conclusions To improve the progress of controlling iodine deficiency disorders,the government should fully carry on its responsibility,giving supports both of policy and funds.Salt administrative sector should make favourable policies to benefit the local population.And health sector should coordinate the related sectors,and reinforce the health education and surveillance.

Objective To investigated the protective ways of intensity modulated radiotherapy (IMRT)for submandibular gland function in patients with nasopharyngeal carcinoma.Methods From March 2010 to November 2012,101 patients with nasopharyngeal carcinoma were enrolled into study.They were treated with IMRT and evaluated by face to face dry mouth questionnaire during the follow-up of 3,6,12,18,24 and more than 24 months,meanwhile,their dose volume histogram of submandibular gland were taken into consideration.Results The average contralateral median dose and that of ipsilateral submandibular gland were (45.69±7.22) Gy and (51.64±8.20) Gy,respectively,and the V35,V40,V45,V50 were 95.82 ％,69.99 ％,46.90 ％,25.50 ％,and 100 ％,96.50 ％,82.24 ％,60.98 ％,respectively.There were positive relationship between the xerostomia grading of 3,6,and 12 months after radiotherapy and the average dose of submandibular gland or the V35,V40,V45,V50.After 6 month,the xerostomia in 77.2 ％ (78/101) was significantly improved,and after 12 months,less than 5 ％ of patient complained about G3 or more grade of xerostomia.Conclusions When using IMRT in nasopharyngeal carcinoma,it' s necessary to reduce the irradiated volume and the dose of submandibular gland.It is confined that the median dose of contralateral submandibular gland should be less than 40-45 Gy,and V40 or V45 ≤66.7 ％ or ≤50 ％,which can effectively protect the function of salivary gland.

ObjectiveTo identify the early predictors of refractory epilepsy (RE). MethodsAll 173 epileptic patients with correct diagnosis and reasonable treatment were enrolled. The 106 patients were classified as drug non-responsive epilepsy (DNR-EP). The remaining 63 patients were classified as drugresponsive epilepsy (DR-EP). With multiple logistic regression, the clinical characteristics between the two groups were compared to identify the early predictors of RE. ResultsMultiple logistic regression analysis demonstrated that more than 10 seizures before treatment (OR =4. 46, 95％ CI 1.60-12. 40, P =0. 004),mental retardation at early time ( OR =19. 87, 95％ CI 3. 60-109. 78, P =0. 001 ) and abnormal electroencephalogram(EEG) with epileptiform wave after treatment ( OR =7.57, 95％ CI 2. 54-22. 56,P ＜0. 01 ) were independent predictors of RE.Response to initial therapy was a protective factor of RE (OR=0.05, 95％ CI 0.018-0. 139, P＜0.01). ConclusionPatients who have many seizures before treatment, mental retardation at the early time, epileptiform abnormality in EEG after treatment and who are resistant to initial therapy are likely to develop into refractory epilepsy.

OBJECTIVETo investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).

METHODSWe reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.

RESULTSThe patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.

CONCLUSIONUMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.
