Objective To investigate the infectious complications after nonmyeloablative allogeneic peripheral blood stem cell transplantation (NASCT). Methods Ten patients with leukemia received NASCT from HLA-identical or 1-3 antigen mismatched sibling donors with conditioning regimens of Flu/Cy+BU+ALG. Five patients were acute leukemia (AL) and all of them is in complete remission (CR1). Cyclosporine in combination with methotrexate was administered for GVHD prophylaxis. Results WBC recovered to more than 0.5 ?10 9/L during postoperative 10 day to 38 day and platelet recovered to more than 20?10 9/L during postoperative 8 day to 16 day. Bacterial infections occurred in 3 patients (30 %) and cytomegalovirus (CMV) infections in 2 patients (20 %). Varicella zoster virus (VZV) infections occurred in one patient (10 %). No fungal infections were documented. No patients died as a result of infection . Conclusion NASCT is a safe and effective therapeutic method for leukemia. It reduces acute GVHD,regimen-related toxicity and early neutropenia associated with traditional allo-HSCT.

Integrating visualization toolkit and the capability of interaction, bidirectional communication and graphics rendering which provided by HTML5, we explored and experimented on the feasibility of remote medical image reconstruction and interaction in pure Web. We prompted server-centric method which did not need to download the big medical data to local connections and avoided considering network transmission pressure and the three-dimensional (3D) rendering capability of client hardware. The method integrated remote medical image reconstruction and interaction into Web seamlessly, which was applicable to lower-end computers and mobile devices. Finally, we tested this method in the Internet and achieved real-time effects. This Web-based 3D reconstruction and interaction method, which crosses over internet terminals and performance limited devices, may be useful for remote medical assistant.

To study the quantitative structure-activity relationship (QSAR) between the stuctures of 29 flavonoids and the inhibitory activity of their multidrug resistance-associated protein (MRP) 1 and 2 by using the comparative molecular similarity index analysis (CoMSIA). By studying the impact of the combination of different molecular force fields, researchers obtained the molecular force fields that played an important role in inhibiting the activity of MRP1 and MRP2, built the optimized QSAR model, and discussed the structural modification method for flavonoids' multidrug resistance-associated protein inhibitor. The results of the study could not only provide the guidance for new drug R&D, but also help partially discuss the synergy mechanism between MRP1 and MRP2 receptors and traditional Chinese medicines containing flavonoids.

Background and purpose:With the development of the three-dimensional (3D) science, minimally invasive technology is going into the 3D period. While 3D laparoscope system has been widely accepted by surgeons because of its better visual effect and safer operations compared to traditional laparoscope system, this study aimed to evaluate the feasibility of 3D thoracoscope system in minimally invasive surgery for the treatment of thoracic diseases. Methods: A total of 96 cases of thoracic diseases were accomplished with KARL STORZ 3D thoracoscope during Mar. 2014 to Oct. 2014, including 33 cases of lobectomy, 2 cases of segmentectomy, and 10 cases of wedge resection of pulmonary tumor, 27 cases of mediastinal tumor, 20 cases of esophageal tumor and 4 case of esophageal achalasia. The data of operative time, bleeding volume, postoperative chest tube drainage and hospital time and postoperative complications were counted. Results: All the operations were completed successfully, without conversion to open surgery. All the operations cost 30 to 237 min. The operation of local resection lasted 30 to 120 min, with an average of 52 min, the operation of pulmonary lobectomy lasted 63 to 122 min, with an average of 75 min;the operation of mediastinal tumor resection lasted 35 to 125 min, with an average of 77 min;and the operation of esophageal diseases lasted 57 to 237 min, with an average of 189 min. The bleeding volumes were 2 to 85 mL, 15 to 72 mL, 30 to 186 mL and with the average of 50 mL, 47 mL, 118 mL in pulmonary, mediastinal and esophageal operations respectively. The time of postoperative chest tube drainage of each surgery was 1 to 5 days after pulmonary operations, 1 to 3 days after mediastinal operations, and 2 to 6 days after esophageal operations. The postoperative hospital time of pulmonary operation was 2 to 10 days, with an average of 6.3 days;the time of mediastinal operation was 3 to 6 days, with an average of 4.2 days;and the time of esophageal operation was 4 to 19 days, with an average of 13.3 days. No complications and tumor recurrence or metastasis were observed during the followed 3 months. Conclusion: 3D thoracoscope system not only preserves the minimally invasive advantage of video-assisted thoracoscopic surgery (VATS), it can also provide high-definition and stereoscopic vision and better sense of depth which facilitate the operation more precise and safer, thus operation time becomes shorter. Besides, 3D system possesses the advantage of natural vision similar to open surgery, thus it has an easier and shorter learning curve.
