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 explore the blood sugar controlling for elderly patients with fracture and diabetes mellitus. Methods Twenty patients with fracture complicated with diabetes were managed with mental education and diet controlling. Meanwhile nursing measures were done to prevent infections, bedsores and deep vein thrombosis (DVT). Results The fasting blood sugar levels of the 20 elderly patients were well controlled below 7.8 mmol / L. There were no related complications. Conclusion Such nursing measures as psychological counseling and diet control are helpful for a steady maintenance of blood sugar for feasibility of surgical operation, to ensure successful manipulation of the surgical operation. Prevention of infection, bedsore and DVT is critical for ensuring the success of operations.

Objective To investigate the changes of waist muscle density and area in the subjects with spiral CT scan examination,and through the quantitative analysis of different age and gender to get the degree of lumbar muscle degeneration.Methods 240 cases of lumbar CT scan reconstruction images (including the patients suffering from low back pain)were collected.According to the age,20 - 29 years old group,30 - 39 years old group,40 -49 years old group,50-59 years old group,60-69 years old group,and 70-79 years old group were set up.The lumbar transverse psoas muscle,lumbar side muscle,erector spinae cross-sectional areas (CSA)and mean CT values were measured at different levels.Scanning equipment:Toshiba Activion 16-slice spiral CT scanners, acquisition range from the waist 1 to S1.Results ①Compared between the measurement results of the same age groups (except 70-79 years old group),the average CSA of the male at the same level waist was higher than the female (P <0.05).②Compared between the same level groups of 20-29 years,30-39 years and 40-49 years, there were no significant differences (P >0.05).Compared between the same level groups of 50-59 years,60-69 years and 70-79 years,there was no significant difference (P >0.05).③Compared the CSA of man’s erector spinae muscle between 40-49 years group and 50-59 years group,there were significant differences (P <0.05).④Compared the same level CSA of female between 20-29 years,30-39 years,40-49 years,50-59 years,60-69 years,70-79 years groups,and the adjacent groups,there were no significant differences (P >0.05).⑤The same level average density of erector spinae muscle was lowest compared with the psoas major muscle and quadratus lumborum muscle,and falling faster,the psoas major muscle was relatively higher.The same level average density of female’s erector spinae muscle was lower than man’s,specially in 70-79 years group.Conclusion Multi-slice spiral CT can be used to diagnose the lumbar degenerative conditions.

BACKGROUND:PA6 cells are bone marrow stromal stem cells from the mouse skul , and scientists have found that PA6 cells co-cultured with some kinds of stem cells have shown neural differentiation, based on which, PA6 cells can be used for repair of nerve injury. Therefore, researchers give more and more attentions to PA6, but few studies have addressed isolation and culture methods of bone marrow stromal stem cells from the skul . OBJECTIVE:To isolate and culture bone marrow stromal stem cells from the skul of Sprague-Dawley rats and to observe cellular morpholopy in vitro and perform immunofluorescence identification. METHODS:Under sterile conditions, newborn Sprague-Dawley rat’s skul was cut into pieces. Smal skul pieces were washed using Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum. Single cellsuspension was made, and placed in culture flask. The culture medium was changed many times for cellpurification. The second passage of cells was obtained for morphology observation under an inverted microscope. cellsurface markers were detected by using immunofluorescence staining. RESULTS AND CONCLUSION:After the primary culture for 24 hours, cells exhibited adherent growth;after 3 days, cells were increased in number, and presented with irregular shapes, such as polygon, triangle, spindle and flat shape. After passage, cells were uniform in morphology, arranged in radial and bunch patterns, and exhibited strong adherent ability. Some cells grew in cluster, and proliferated faster than primary cells. Immunofluorescence staining showed that cells were positive for CD105, CD73, CD44, CD90, but negative for CD45, D34,CD14, HLA-DR. Results indicate that this method can obtain bone marrow stromal stem cells.

Objective To study MR manifestations of biliary obstructive disease.Methods MR examination (Philips Gyroscan INTERA 1.0T)in 69 patients with biliary obstructive disease were performed.The conventional sequences included:T1WI/FFE,T2WI/TSE,T2WI/SPIR and contrast-enhanced at axial position,coronal B-FFE and MRCP.All images in all cases were compared with the results of operation and pathology.Results 43 cases were benign disorder,of them,42 cases were choledocholithiasis,one case was choledochal cyst.Choledocholithiasis presented as single or multiple round or ovoid with low signal.The direct sign of malignant lesions (26 cases) was the masses with slightly high signal at the obstructive part,the indirect sign of malignant lesions was obstruction or narrow of bile duct. The MR diagnostic accuracy of obstructive location was 100%, and the accuracy for evaluating the causes of obstruction was 89.9%.Conclusion MRCP combining with B-FFE and routine MRI, analysising the direct sign and indirect sign, can improve the diagnostic accuracy of obstructive jaundice.
