Advances in clinical transformation research has facilitated discovery of a number of novel somatic mutations and aberrant intracellular signaling pathways involved in malignant proliferative B-cell lymphoma.Meanwhile,small molecular inhibitors targeting those mutation genes or signaling pathways have also been shown to be effective in treating relapsed and refractory B-cell non-Hodgkin lymphoma.This paper reviewed important discoveries in clinical transformation research in lymphoma field in 2013.

Objective To investigate the related factors and preventive measures of nasopharyngeal massive hemorrhage in patients with nasopharyngeal carcinoma after radiotherapy. Methods Clinical data of 43 nasopharyngeal massive hemorrhage patients with nasopharyngeal carcinoma after radiotherapy were analyzed retrospectively. Results Thirty-nine cases(90.7 %) had abroad skull base invasion due to tumor, 36 cases (83.7%) received high dose of radiation, and 13 cases (30.2 %) were accompanied by diabetes. Conclusion Tumor location is the major factor for nasopharyngeal massive hemorrhage, while radiation dosage, fractionation patterns and diabetes are the secondary factors. The measures in cluding hyperfractionation, overall dose control and blood sugar regulation should be taken for the high risk patients. Prevention is more important than salvage.

Rituximab in the combination of CHOP regimen has been widely used as the standard treatment of several kinds of B cell non-Hodgkin lymphoma (B-NHL),but there are still about 1/3 of the late B-NHL patients become primary and secondary resistant to the drug.Recently,many translational research progress in malignant lymphoma promoted the development of promising candidate drugs for the treatment of lymphoma.The advances in translational research field were summarized in this manuscript.

OBJECTIVE:To provide experience and reference for the reform ofintegration of medicine and nursingunder the strategy ofHealth China 2030. METHODS:By literature analysis,the demand characteristics and supply situation ofinte-gration of medicine and nursingservice model in China were analyzed. The development bottleneck ofintegration of medicine and nursingservice model in China was discussed to put forward countermeasures and suggestions. RESULTS&CONCLUSIONS:Integration of medicine and nursingis a new model of the development of pension services in China. Throughout whole country, it is still in the stage of exploration and practice. There are some problems,such as serious inadequate beds,low participation of private pension institutions,pension service quality ofintegration of medicine and nursinghaving to be improved,weak market competition of pension institutions,social forces participation having to be improved,big demand gap of medical and nursing staff,inadequate high-quality medical and nursing talent. A clear positioning ofintegration of medicine and nursingservice model in China should be put forward andintegration of medicine and nursingmonitoring system should be improved. It is suggested to establish service complaint mechanism of pension institutions,encourage the active participation of diverse social forces,broaden the financing channels ofintegration of medicine and nursing,build service information sharing platform ofintegration of medi-cine and nursing,establish electronic health records for the elderly and set up maintenance personnel training mechanism so as to promote the rapid development of the reform ofintegration of medicine and nursing.

Objective To observe the treatment and outcomes of gastric stump cancer(GSC) after subtotal gastrectomy,and to analyse the possible related factors for the development of GSC. Methods The clinical data of 693 patients with subtotal gastrectomy were retrospectively analysed.The development,treatment and outcomes of GSC were observed,and the possible factors associated with the development of GSC were analysed. Results Seventy-six cases of GSC emerged in the 693 patients with subtotal gastrectomy.Fifty-one of the 76 cases were perfomed radical operations(n=36) or palliative resection(n=15).No death was found during the perioperative period,and the median survival time was 32.7 and 14.2 months,respectively.Those 25 without surgical management died 3 to 11 months after the development of GSC.Among the 76 cases with GSC,stomach was found as the original site of ulcer in 59(22.3%,59/259),and duodenal bulb in the other 17(3.9%,17/434)(P

Objective To investigate the effect of sevoflurane pretreatment on the expression of tight junction protein Occludin and ZO-1 in the lung following ischemia-reperfusion (I/R) injury in rats. Methods Ninty-six adult male Wistar rats weighing 250-350 g were randomly divided into 4 groups ( n = 24 each): group Ⅰ sham operation (group S);group Ⅱ I/R; group Ⅲ sevoflurane (group Sevo) and group Ⅳ Sevo + I/R. The animals were anesthetized, tracheostomized and mechanically ventilated. Right femoral vein and left carotid artery were cannulated for BP monitoring, blood sampling and drug and fluid administration. Lung I/R was induced by clamping left pulmonary hilum for 45 min followed by 120 min reperfusion in group Ⅱ and Ⅳ. In group Ⅲ the animals inhaled 2.2 % sevoflurane for 30 min. In group Ⅳ the animals inhaled 2.2 % sevoflurane for 30 min before lung ischemia. Six animals were killed at the end of 45 min ischemia (T1), and 60 and 120 min of reperfusion (T2, T3 ). The lungs were immediately removed for determination of W/D lung weight ratio and the expression of Occludin and ZO-1 protein (by Western blot). Tissues of lung were obtained for observation of histopathology with light microscope. Lung permeability index (LPI) was calculated. Another 6 animals were killed at 120 min of reperfusion for lung lavage. Results I/R significantly increased W/D ratio and LPI and significantly reduced Occludin and ZO-1 protein expression in the lung tissue as compared with group C and Sev. Sevoflurane pretreatment significantly attenuated the I/R-induced changes. The pathological damage to the lung tissue was significantly less in group SP than in I/R. Conclusion Sevoflurane pretreatment may protect the lungs from I/R injury by up-regulating the expression of Occludin and ZO-1.

Objective To evaluate the risk urodynamic factors of upper urinary tract deterioration in children with neurogenic bladder dysfunction secondary to myelodysplasia. Methods Urodynamic and imaging studies were performed in 32 children with myelodysplasia. Results 18 patients had ureterohydronephrosis and 4 of them had vesicoureteric reflux.Of 19 children with detrusor leak point pressure higher than 40 cmH 2O and bladder compliance less than 40ml/cmH 2O, upper tract deterioration was revealed in 17.In contrast,of 13 patients with detrusor leak point pressure less than 40 cmH 2O and bladder compliance higher than 40 ml/cmH 2O, only one had bilateral ureteral dilatation( P

Objective To probe the reasons of failure of caged cervical intervertebral fusion and define the indications, operative techniques and short term results of the revision surgery. Methods Twenty-seven cases of caged cervical fusion were revised. The indication for fusion was cervical disc herniation in four cases and cervical spondylotic mylopathy in 23 cases. Of the 27 cases, there were 8 single levels, 15 double levels, 4 three levels. The intervals from revision to primary fusion were 2-25 months, 10.3 months in average. Patients presented discomfort (22 cases) and local pain of neck and shoulder (9 cases) or paralysis (19 cases) preoperatively. JOA grade was mean 11.6 points before revision. Radiographic examination showed the mean lordosis loss was 7.1 mm, the mean interbody height loss was 3.9 mm. 24 patients presented kyphosis. Occluded neighboring cages were found in multilevel cases. Nonunion was founded in 6 cases, unstable in 9 cases, compression still existed in 19 cases. Removal of cages and then decompression, bone grafting and anterior plating fixation were performed in 23 cases (29 cages). 16 patients underwent further posterior fixation. Posterior revisions underwent in another 4 cases (9 cages), including laminectomy and reshaping the lordosis and lateral mass screw plating fixation. Results All the cases were followed-up from 4 to 26 months, 11.7 months in average. The local symptoms released in 81% patients. Nerural deficit symptoms improved in 58% patients. Mean JOA grade was 14.2 points after revision. In 23 cases of anterior approach revisions, 17 cases obtained bone healing within 3 months, while 6 cases got delayed union. The kyphosis was corrected, and the intervertebral height increased 3 mm in average. There were no nerural impaction or failed internal fixation. Conclusion Deficient decompression, sinking of the cage into the cancellous bone of the vertebral body and subsequent kyphosis and bone graft nonunion consist of the main causes for revision surgery. The indications of revision are aggressive neurologic symptom, unstable or deformity of the cervical spine. Cage removal, completely decompression, bone grafting and secure fixation are major steps of revision procedure. In case of more than 3 fusion levels, further posterior fixation is advised.
