Objective To investigate the way of improving the diagnosis and cure rate of pulmonary synovial sarcoma.Methods One case of pulmonary synovial sarcoma was selected,at the same time accompanied with 80 cases of pulmonary synovial sarcoma with complete data referenced from China Journal Full-text Database on October 2012 were retrospectively studied.The main clinical manifestations,imaging characteristics were analyszed.According to the pathology,immunohisochemistry and molecular biology for diagnosis and discrimination,in order to reduce the misdiagnosis.Results All of 81 patients,40 male cases and 41 female cases,the main clinical manifestations were chest pain,difficult breathing,hemoptysis and cough.In individual cases without any discomfort.All cases had not been accurately diagnosed before surgery.Ultimately diagnosis of patients depend on histopathology and immunohistochemistry.Conclusions Pulmonary synovial sarcoma shows different clinical symptoms but specific imaging characteristic and maybe confused with other pulmonary tumors or inflammation.Histopathological,immunophenotypic and fusion gene detection is the mainly technics for diagnosis.Surgery is the primary therapy,patients undergoing uncompletely resection have a poor prognosis.

OBJECTIVETo study the activation of platelets in children with Kawasaki disease (KD) at molecular level.

METHODSThe expression of platelet surface glycoproteins CD(41), CD(42a), CD(61), CD(62p) and CD(63) in 20 KD patients was measured by flow cytometry before and at 1, 2, 3 week after treatment with aspirin and high-dose (1 approximately 2 g/kg) intravenous gamma-globulin (IVIG).

RESULTSThe expression of glycoprotein CD(41), CD(42a), CD(61), CD(62p) and CD(63) were higher in KD group than in control group. Aspirin and IVIG could not inhibit these high expression of glycoproteins. Higher expression of CD(62p) was observed in patients with coronary artery injury.

CONCLUSIONPlatelets were highly activated in KD patients which may be one of the most important pathophysiological step in KD. It provided a theoretical basis for treatment of KD with antagonist of glycoprotein of platelets. Obviously increase of CD(62p) can be taken as a criterion for predicting coronary artery injury in KD patients.

Objective: To investigate the clinical characters and diagnosis and treatment in patients with vesicoenteric fistula. Methods: Two patients with vesicoenteric fistula were admitted to the Affiliated Hospital of Shanxi Datong University in 2012 and 2019, at the same time 64 cases with complete data referenced from China Journal Full-text Database from September 2001 to December 2018 were retrospectively studied. The pathogeny, main clinical manifestations, relevant examination, treatment methods and prognosis were analyzed, to explore the best diagnosis and treatment of vesicoenteric fistula. Results: Among all of 66 patients, there were 49 males and 17 females. The pathogeny included intestinal cancer in 31 cases (46.97%), Crohn disease in 11 cases (16.67%), intestinal diverticulitis in 10 cases (15.15%), bladder cancer in 8 cases (12.12%), appendicitis and other inflammatory diseases in 5 cases (7.58%) and intraoperative injury in 1 case (1.52%). The main clinical feature included recurrent urinary tract infection in 45 cases (68.18%), fecaluria in 43 cases (65.15%), abdominal pain in 16 cases (24.24%) and pneumaturia in 16 cases (24.24%). Forty-one cases underwent CT examination, and the diagnostic rate was 58.54% (24/41); 47 cases underwent cystoscopy, and the diagnostic rate was 55.32% (26/47); 34 cases underwent cystography, and the diagnostic rate was 44.12% (15/34). Six cases (90.91%) were treated with surgery, and no perioperative death occurred. Twenty-eight cases were followed up, and the mean follow-up time was 4.1 years. Seven cases died of tumor recurrence and metastasis; 2 cases died of other basic diseases such as cardiovascular and cerebrovascular diseases. No other patients with benign vesicoenteric fistula died during follow-up. Conclusions The major cause of vesicoenteric fistula is intestinal malignancy, which shows emblematic clinical symptoms, and specific imaging characteristic. CT, cystoscopy and cystography are the main diagnostic technique. Surgical intervention is the major therapeutic choice, and the prognosis depends on the primary disease.
