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.

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 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.

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 observe the bone mineral density(BMD)in type 2 diabetic women and discuss the methods for evaluation of BMD.Methods BMD was measured by dual-energy X-ray absorptiometry(DEXA)at skeletal regions of supine and lateral spine,left femur neck and left hip in 484 type 2 diabetic women and 868 healthy women.The relation of BMD of healthy women in skeletal regions with age changes was found to fit a cubic regression model.Results The peak BMD of lateral spine and hip appeared at 25-34 and 35-44 years old respectively.BMD in diabetic women was not different from age-matched healthy women.The BMD values of the different age stages in diabetic women showed no difference(P>0.05)as compared with healthy women,and decreased with the age increase.The numbers of damaged bone sites were increased with the age increase.The BMD difference values between peak value and values of different age stages showed no difference between diabetic and healthy women groups(P>0.05).Conclusion The changes of BMD in type 2 diabetic women show no difference from age-matched healthy women.And in both diabetic and healthy women,BMD decreases with age increasing.

Objective To observe the effect of Cyclosporine A on the brain immunoligical reject reaction of transgenic cellular transplant in rats with experimental brain hemorrhage.Methods We established the brain hemorrhagic models of rats and the models were divided into group A (treated with Cyclosporin A) and group B (without treatment) randomly after transplanting brain cells modified by NGF gene. The levels of CD~+_4, CD~+_8T cells subsets in peripheral blood were examined by using flow cytometry at 15 d after transplantation. The expressions of MHC-classⅡantigens and infiltration of CD~+_4, CD~+_8T lymphocyte subsets were examined by SP immunocytochemical stain.Results The count of CD~+_4, CD~+_8T lymphocyte and CD~+_4/CD~+_8 in peripheral blood were 29.20?3.97, 20.65?2.02 and 1.41?0.86 in group A, and were 47.39?3.01, 28.30? 2.36 and 1.68?0.69 in group B, respectively.There were significant differences between the two groups (all P

Objective To study pathological diagnostic value of forceps and brush biopsy cytological examination by percutaneous transhepatic cholangiodrainage(PTCD) for malignant obstructive jaundice.Methods From April 2005 to April 2006,24 cases of obstructive jaundice underwent PTCD and stent insertion in biliary tract.Tissue pathological examination by forceps and brush was done during PTCD.Results 24 cases received forceps biopsy,of whom,14 cases received brush cytological examination at the same time.All of the 24 cases of forceps biopsy obtained pathological tissue and the pathological results as follows: adencarcinoma in 15 cases,4 cases had allotype cells,regarded as positive results;inflammation tissue in 1 case,which was restenosis after stent insertion;fibrous tissue in 1 case;tissue obtained was cholangioepithelia in 3 cases,in which 1 case was diagnosed as lymph node metastasis of peripheral head of pancreas after gastric cancer operation,2 cases were diagnosed as cholangiocarcinoma,the positive rate of forceps biopsy being 79.2%(19/24).4 cases of cytological examinations by brush showed tumor cells in 2 cases,allotype cells in 2 cases,regarded as positive results,the positive rate being 28.6%(4/14),and others were negative results.Conclusions Intracholangio-biopsy by PTCD offers the advantages of simplicity,safety,higher accuracy and less complications.Pathological diagnosis can be obtained at the same time during reducing-jaundice therapy by PTCD.
