Chinese Journal of Neurology 2015;48(6):514-520
Objective To discuss the correlation of Wiskott-Aldrich syndrome (WAS) with autoimmune disease of the central nervous system and its possible pathogenesis by reporting one case of the disease and reviewing related literature.Methods One case of WAS complicated with demyelinating disease of the central nervous system was reported.The patient' s clinical symptoms,laboratory examinations (such as blood tests,immune function tests,etc) and imaging features were analyzed.The patient's blood DNA was extracted and performed gene testing.And related literature was reviewed.Results The patient showed typical clinical symptoms of WAS,including eczema,thrombocytopenia and immune deficiency,complicated with demyelinating disease of the central nervous system.The DNA testing showed C400G > C p.(ALa134Pro) mutation,which is a missense mutation.The 134th amino acid in protein was changed from alanine to proline.The patient also showed the symptoms of demyelinating disease of the central nervous system,which drew our attention.This was the first report on WAS complicated with demyelinating disease of the central nervous system,which was perhaps caused by a gene mutation.Conclusions WAS complicated with demyelinating disease of the central nervous system is possibly resulted from the gene mutation,which leads to the expression disorder of WAS protein.And then non-red hematopoietic cells lead to signal transduction and cytoskeleton recombination disorders in response to environment stimulus,which produces lymphocytes immigration,signal transduction and immune synaps formation disorders.

Purpose:To explore the problems in the treatment of the elderly patients suffering from colonic carcinoma.Methods:182 cases of elderly patients aged over 70 who received operation for colonic carcinoma during Jan 1994 to Dec 1998 were analyzed retrospectively. Results:176 cases underwent resections (resection rate 96.7%), of which 129 cases(70.9%)had radical resection and 47 cases(25.8%)palliative resection. 6 cases(3.3%)experienced simple colostomy or bypass. Postoperative complications were found in 67 cases (36.8%),of which 8 cases died during perioperation period(mortality rate 4.4%). Conclusions:Old age is not the major determining factor when considering surgical operation as the treatment for colonic carcinoma patients. In order to enhance resection rate especially radical resection rate and survival rate,to diminish postoperative complications and mortality, and thus to improve the quality of life for the elderly colonic carcinoma patients, a series of measures must be taken. First, diagnosis and treatment of the associated conditions must be emphasized. Second, full preoperative preparations with appropriate choice of the time and procedure for operation, as well as exact operation principles must be followed. Finally, intensive monitoring during the perioperative period and prevention and treatment of postoperative complications were also important factors to be considered.

Objective To find out the significance of different radiologieal examinations in the di-agnosis of the prostate carcinoma through studying their radiological misdiagnosis rate. Methods By searching for patients having radiological examination results in the database of prostate carcinoma in Tianjin,got the patients whose examination results were different from prostate carcinoma. Analyzed the misdiagnosis rate of each kind of imaging diagnosis using x2-test retrospectively. Results In all patients searched, the misdiagnosis rate of transabdominal ultrasonography, transrectal uhrasonography (TRUS), CT , MRI was 45.1%, 10.1%, 34.5% and 7.5% respectively. Statistical analysis showed that the misdiagnosis rate of MRI was the lowest, then TRUS, and CT. Transabdominal ultrasonography had the highest misdiagnosis rate. There was not significant difference between MRI and TRUS. Conclusions As an efficient and important screening method, transabdominal ultrasonography still need to get a higher definite diagnosis rate. TRUS don't have obvious advantages over pelvis MRI in the diagnosis of prostate carcinoma except its usefulness in the biopsy of prostate. Pelvis MRI is still the most important imaging diagnosis of prostate carcinoma and should be first choice because of its noninvasive intervention, convenience and lowest misdiagnosis rate.

Vorapaxar,a novel antagonist of the protease-activated receptor 1 (PAR-1 ),can inhibit the clotting process. Deuterium-labeled vorapaxar was required for the analysis of clinical sample as an internal stand-ard. Starting for unlabeled vorapaxar,four-step reactions including hydrolysis,condensation,transesterification and hydrogen-deuterium exchange were carried out to synthesize [D8]vorapaxar effectively for the first time. All intermediates and final products were confirmed by NMR and high resolution mass spectrometry (HRMS).Impor-tantly,the prepared [D8]vorapaxar could meet the requirements of sample analysis as the internal standard.

Objective To describe the characteristics of radiation induced mucositis in patients withhead and neck cancer ( HNC) during radiotherapy, and analyze the effect of radiation induced mucositis on diet patterns and weight change and the influencing factors for radiation induced mucositis. Methods Patients with HNC treated with radiotherapy in one cancer hospital were recruited. Data were collected before, during and at the end of the radiotherapy, which included radiation induced oral and pharyngeal mucositis, pain during eat-ing, diet patterns and weight. Results Two hundred and two patients were completely investigated and 43.5%and 34. 2% of the patients suffered from moderate to severe (≥grade 2) oral mucositis and pharyngeal mucosi-tis, respectively during the radiotherapy. At the end of radiotherapy, 53. 5% and 51. 5% of the patients suffered from moderate to severe oral mucositis and pharyngeal mucositis (≥grade 2 ) , respectively. Oral and pharyngeal mucositis were significantly correlated with pain during eating, diet patterns and weight ( P<0. 05) . Tumor site was the main reason that affected the severity of mucositis ( Wald χ2 =26. 033, 14. 216;P<0.001). Conclusion Radiation induced mucositis was gradually aggravated with radiotherapy progress, which is closely related to pain during eating, change of diet patterns and weight loss. The severity of mucositis is re-lated to the tumor site. Measures should be taken to strengthen the management of adverse reactions and nutri-tional status of patients.
