Objective To evaluate the clinical feature of adult acute myeloid leukemia with nucleophosmin (NPM1) cytoplastic positive (NPMc+AML), and to investigate the significance of the NPM1 gene mutations regularly in detecting the early relapse. Methods The NPM1 gene mutations was screened by the PCR-capillary electrophoresis in 95 newly diagnosed adult AML patients. 5 complete remission AML patients were selected to detecte the NPM1 gene mutations regularly. Results In 95 cases of adult AML patients, the incidence of the NPM1 mutations was 9.5 % (28/95). The incidence of the NPM1 mutations in patients (≥40-year-old) was higher clearly than it' s in pazients (40-year-old) (λ 2= 6.963, P = 0.012). That in the AML patients with normal karyotype (51.1%) was higher than that in the patients with abnormal karyotype (8.3 %) (λ2= 20.860, P= 0.0000). NPM1 mutations occured with a considerate percentage in AML patients with M5/M2 subtype. In AML with recurrent genetic abnormalities the NPM1 mutations wasn' t found.The white blood cell count, platelet count, lactate dehydrogenase in the NPMc+AML patients were clearly higher than that in the NPMc-AML patients (t were individually 4.132, 4.603, 4.069, P <0.05). The rate of complete remission, relapse-free survival and overall survival in the NPMc+AML patients were also higher than that in the N PMc-AML patients (λ 2 were individually 10.448, 4.146, 4.384, P <0.05). In cases detected regularly NPM1 mutations preceded the hematological relapse about 1.5-2 months. Conclusion NPM1 gene mutations has a higher incidence in adult AML, particularly in normal karyotype AML. The clinical manifestations are older, and higher in white blood cell count, platelet count, and lactate dehydrogenase. The NPM1 mutations in adult AML is a good factor for prognosis. The regular detection of NPM1 mutation could find relapse early.

Objective To investigate the diagnosis and treatment in patients with acute myocardial infarction (AMI) and complicated left ventricular wall rupture (LVWR). Methods A retrospective analysis was made on the clinical features, diagnosis and successful treatment in three AMI patients with LVWR from December 2015 to April 2016. Results Three cases were included in this study. Case 1, the mesh like cardiac rupture after AMI was diagnosed by ultrasonic Doppler. Emergency revascularization was performed due to the combined cardiac shock, and the infarct related artery was opened. The vasoactive drugs were used after revascularization to reduce ventricular pressure load and volume load in the haemodynamic monitoring, and anticoagulation, antiplatelet agents were less used or discontinued to promote local thrombus healing of ventricular rupture. Case 2 was a recurrent myocardial infarction patient. LVWR was diagnosed by ultrasonic Doppler one day after emergency operation. The ruptured ventricular wall was encapsulated by thrombus. The drug therapy was effective in hemodynamic monitoring. LVWR was further confirmed by cardiac CT after clinical stabilization. Case 3 was diagnosed LVWR by ultrasonic Doppler four days after AMI. Because the ruptured ventricular wall was limited by incompletely organized thrombus, and the haemodynamic condition was stable, selective surgical repair of rupture after coronary angiography was performed. Conclusion The effective drug therapy combined with percutaneous coronary intervention and surgical repair can reduce the risk of death in patients with LVWR after AMI.

Objective To compare the accuracy of endoscopic ultrasound (EUS) with double contrast enhanced ultrasound ( DCUS) in the preoperative staging of gastric malignancies. Methods This study included 162 patients with biopsy proven gastric cancer who underwent surgical resection as primary management of their malignancies. All patients underwent DCUS and EUS prior to surgical intervention with the results of the ultrasound findings compared with the pathological stages of the resected specimen. Results Among the 162 gastric cancer patients, there were 42 cases of T1, 49 cases of T2, 56 cases of T3, and 15 cases of T4 tumors. The overall accuracy of DCUS and EUS for the determination of loco-regional tumor infiltration ( T Staging) was 77. 2% and 74. 7% , (χ2 = 0. 273, P = 0. 603). Comparison of ultrasound techniques revealed that DCUS was superior to EUS only for a tumor depth of T3 (χ2 =5. 009, P = 0.025). Lymph nodes were correctly staged with DCUS and EUS in 78.4% and 57. 4% of cases, respectively ( χ2 = 16. 370,P =0.001). Using DCUS, the sensitivity of the technique was 78. 4% with a specificity of 78. 5%. In comparison, EUS had a sensitivity of 49. 5% with a specificity of 69. 2%. DCUS also detected a higher incidence of positive lymph nodes than EUS for poorly differentiated (81. 5% vs. 42. 6% ,χ2 =17. 338, P < 0. 01) and overall tumor types (78.4% vs. 49. 5% , χ2 = 17.523, P < 0. 01). Conclusions Double contrast-enhanced ultrasonography offers another noninvasive approach for the preoperative evaluation of gastric cancer. DCUS was comparable to EUS in tumor depth evaluation. DCUS offers an advantage in the detection of lymph node metastases, especially in poorly differentiated tumors.

Peripheral nerve injury (PNI) is an important clinical complication, which brings long-term physical and psychological pain and economic burden to patients. There is no satisfactory treatment plan for PNI. Although microsurgery technology has been greatly developed, some peripheral nerve defects or ruptures caused by external forces can be repaired by surgery or nerve transplantation. However, due to the weak ability of nerve cell regeneration and surgical operations may cause damage to the injured nerves, the patient's functional recovery may not be able to achieve the desired effect. Therefore, it is urgent to find a safe and effective method to treat PNI. Mesenchymal stem cells have special differentiation potential and can differentiate into a variety of cell types in vitro and in vivo, and have received widespread attention from researchers. In this paper, the research progress of mesenchymal stem cells in nerve injury repair was summarized, and the characteristics, functions of mesenchymal stem cells and the mechanism of action in peripheral nerve injury repair were reviewed.
