Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of non-Hodgkin's lymphoma.An uncommon subset with myc and either bcl-2 or bcl-6 rearrangement,also known as ‘double-hit’ lymphomas,is considered very aggressive clinical course and poor prognosis despite high-intensity chemotherapy.Recently,these lymphomas have received increased attention.This review explores the existing literatures for the involved genes with their functions,clinical features,diagnosis and treatment.

Objective:In order to improve operator’s cognitive level for standardized disinfection, this paper will focus on analyzing and interpreting the disinfection procedures for some common dialysis machines.Methods: This paper will interpret and compare the disinfection procedures for three brands of dialysis machines in the following aspects: the choice of the disinfectant, the disinfection method, the concentration of the disinfectant and the injected volume of the disinfectant, etc.Results: The procedures of hot disinfection with citric acid were used completely in those three brands of dialysis machine, and the procedure of sodium hypochlorite need been used periodically to remove the proteins and other organic matter.Conclusion:Although the dialysis machines provide almost complete and efficient disinfection procedures, but the operator should need to select the most suitable procedures according to their practical situation. If the operators cannot master the disinfection procedures and have not noticed the importance of it, the wrong operator will lead to incomplete disinfection, affect the normal operation of the dialysis machines and increase the risk of cross-infection.

CONCLUSIONS Realizing a sound organization improving hospital infection management staff and intensive training,increaseing the investment and strengthening th supervision and inspection are in accordance with the law and guide management of patients in rural areas to be assured of a secure medical establishment.

Radiotherapy has become one of the most important treatments for cervical carcinoma. In recent years,because of the organ motion,anatomical changes and setup errors et cetera,the accurate external beam radiotherapy( EBRT)may regard to the difference between the actual dose delivery and the pre-treatment plan,which not only causes target less,but also brings additional doses to the organs at risk( OAR). By using of image guidance and individual modelling,adaptive radiotherapy( ART)can analyze the parameters of target position,volume and dose and adjust optimized plans for the follow-up treatment based on aforesaid feedbacks and enable the enhancement of the local control rate while reducing the incidence of the side reaction.

Objective A total of 86 cases with advanced gastric cancer were randomly divided into XELOX(capecitabine plus oxaliplatin) and FOLFOX4 (5-fluorouracil,leucovorin,and oxaliplatin)groups (n =43 each).The immediate efficacies were evaluated by the criteria of Response Evaluation Criteria In Solid Tumors (RECIST).Adverse reactions were compared between two groups.The overall effective rate were 56％ and 51％ in XELOX and FOLFOX4 groups.And there was no significant inter-group difference (P ＞ 0.05).The incidences of myelosuppression and nausea,vomiting in XELOX group were lower than those in FOLFOX4 group (P ＜ 0.05).And other adverse reactions had no inter-group statistical difference (P ＞ 0.05).Both chemotherapies were comparable in immediate efficacies for advanced gastric cancer.However,XELOX chemotherapy had a lower incidence of adverse reactions and it is more tolerable and compliant for patients.

Abdominal aortic aneurysm (AAA) is a common fatal aortic disease.The rupture of AAA is the procession affected by multiple factors.Besides physiological,pathological and biochemical changes,morphological and biomechanical alteration can also influence this procession.The progress of rupture risk evaluation through morphological and biomechanical characteristics of AAA were reviewed in this article.

Objective To investigate the effects of electroacupuncture at Neiguan point (PC6) and Jianshi point (PC5) combined with granisetron on chemotherapy-induced nausea and vomiting. Methods Seventy-two tumor patients undergoing chemotherapy were randomly divided into an electroacupuncture group (38 patients) and a false electroacupuncture group (34 patients). The electroacupuncture group received electroacupuncture at PC6 and PC5 (1 h, bid) combined with granisetron (3 mg, i.v.) 30 min before chemotherapy, and repeat one time after 12 h. The false electroacupuncture group received electroacupunctur at false PC6 and false PC5, and other treatment same as the electroacupuncture group. Both groups were treated for 3 days. The nausea and vomiting frequencies and clinical effects were compared between the two groups. Results The vomiting frequency in the electroacupuncture group was significantly lower than that in the false electroacupuncture group on day 2 (0.37 ± 0.75 vs. 1.12 ± 2.13;t=2.034, P=0.046). The nausea degree in the electroacupuncture group was significantly lower than that in the false electroacupuncture group on day 2 (1.21 ± 0.93 vs. 1.88 ± 0.59;t=3.596, P=0.001) and day 3 (1.26 ± 0.92 vs. 1.68 ± 0.53; t=2.293, P=0.025). The total effective rate in the electroacupuncture group was significantly higher than those in the false electroacupuncture group on day 2 (76.3% vs. 64.7%; χ2=12.390, P=0.006) and day 3 (73.7%vs. 64.7%;χ2=12.313, P=0.006). Conclusions Electroacupuncture at PC6 and PC5 combined with granisetron can attenuate chemotherapy-induced nausea and vomiting.

OBJECTlVE To investigate the improvement effect of rosigIitazone(ROm)against cis-pIatin(DDP)-induced nephropathy in rats and its mechanim of resistance to oxidative stress. METHODS Invitro:the survivaI rate of HEK293 ceIIs was measured with mTT assay incubated with DDP 0.4 -100 μmoI·L-1 aIone or with DDP 25 μmoI·L-1 and ROm 0.01-1000 μmoI·L-1 for 48 h. Then the content of maIondiaIdehyde(mDA)and the activity of gIutathione(GSH)in HEK293 ceIIs co-incubated with DDP 25 μmoI·L-1 and ROm 100 μmoI·L-1 were assayed using chromatometry. In vivo:sixty maIe SD rats were randomIy divided into normaI controI group,modeI group(DDP 5 mg·kg-1 )and modeI+ROm 5,10 and 20 mg·kg-1 groups. The modeI of DDP-induced nephropathy was estabIished by taiI vein injection of DDP 5 mg·kg-1 ,once a week,for 3 times. After the first injection,the rats in modeI+ROm 5,10 and 20 mg·kg-1 groups were ig given ROm 5,10 and 20 mg·kg-1 ,once a week,for 8 weeks. The bIood urea nitrogen(BUN)and creatinine(Cr)were assessed with an automatic biochemicaI anaIyzer. Nitric oxide(NO)and mDA content,GSH and superoxide dismutase( SOD)activities in the kidney tissue were determined using chromatometry and histopathoIogicaI changes in renaI tissues were detected by hematoxyIin-eosin staining. RESULTS In vitro:IC50 of DDP to HEK293 ceII survivaI for 48 h was 21.0 μmoI·L-1 . Co-incubation with ROm 1-1000 μmoI·L-1 and DDP 25 μmoI·L-1 for 48 h couId signifi-cantIy increase the totaI ceII survivaI rate compared with DDP 25 μmoI·L-1 group(P﹤0.05,P﹤0.01), whiIe co-incubation with ROm 100 μmoI·L-1 and DDP 25 μmoI·L-1 for 48 h couId significantIy decrease the IeveI of mDA(P﹤0.01)and increase GSH activity(P﹤0.01),respectiveIy. In vivo:compared with normaI group,serum BUN and Cr content in modeI group were significantIy increased(P﹤0.01),renaI tissue GSH and SOD activities decreased(P﹤0.01),renaI tissue mDA content increased(P﹤0.01), and renaI tissue NO IeveI and NOS activity aIso decreased significantIy(P﹤0.05). Compared with modeI group,serum BUN content in modeI+ROm 5,10 and 20 mg·kg-1 decreased from(17.0±1.3)mmoI·L-1 to 14.0±4.1,11.2±1.8 and(6.1±1.0)mmoI·L-1(P﹤0.01),serum Cr content in modeI+ROm 10 and 20 mg·kg-1 decreased from(124.6±39.8)mmoI·L-1 to 49.0±5.2 and(47.1±2.9)mmoI·L-1(P﹤0.01), renaI tissue GSH and SOD activities in modeI+ROm 10 and 20 mg·kg-1 group increased significantIy (P﹤0.05,P ﹤ 0. 01),mDA IeveI decreased(P﹤0.05,P ﹤ 0. 01),NO IeveI and NOS activity aIso increased(P﹤0.05,P﹤0.01),and renaI pathoIogicaI tissue damage couId be improved. CONCLUSlON ROm pIays a protective roIe in rat kidney damage caused by DDP,which may be reIated to improving oxidative stress resistance of the kidney.

Attenuated Salmonella can be used not only as live vaccines but also as vectors for exogenous genes. As vectors, attenuated bacteria can deliver genes directly to tumor tissues, leading to the expression of the cloned genes and induction of specific anti-tumor immunologic responses to inhibit tumor growth. Using attenuated Salmonella as a vector offers a new approach for vaccine development.
