Objective To improve the recognition of treatment of adult T lymphoblastic lymphoma (TLL) with Hyper-CVAD regime.Methods The turnovers of 7 cases treated with Hyper-CVAD regime were summarized.Results Among the 7 cases,1 case died after the first unfinished chemotherapy,1 case gained complete remission before autologous stem cell transplantation but relapsed after transplantation,3 cases gained complete remission until now,2 cases without transplantation relapsed and then gave up following treatments after treating with ICE regime or the virgin regime,but the therapeutic effects were poor.Conclusions Adult TLL should get early chemotherapy treatments,and some special characteristics should be noted,the treatment does not relate to the stage,the chemotherapy treatment should be carried out regularly and enough,radiation of mediastinum mass can be applied after 4 cycles of Hyper-CVAD regime,choose suitable transplantation method.

Nasopharyngeal carcinoma (NPC), a common head and neck neoplasm in southern China,is mostly treated with radiotherapy, however, it can not be completely cured by chemoradiotherapy. Recent investigation on NPC suggests that the nasopharyngeal carcinoma stem cells can be differentiated to heterogeneous cancer cells that have a strong ability for self renovation and further contribute to the development and progression of tumor itself which is closely related to drug resistance, recurrence and metastasis of NPC. Wnt/β-catenin, Notch, Hedgehog, NF-κB and mTOR signaling pathways play important roles in cancer stem cells. Study on nasopharyngeal carcinoma stem cells targeted therapies and its related pathways provides a new strategy for the clinical treatment of NPC.

Retinoblastoma(RB)is the most common intraocular malignancy of children with extremely poor prognosis. MicroRNAs are small non-coding single-stranded RNAs in eukaryotic cells, which regulate the expression of gene by mRNA degradation or translation inhibition. MicroRNAs, acting as oncogenes or tumor suppressor genes, are associated with the occurrence and development of RB directly, which is vital for the early diagnosis and clinical targeted therapy of RB. This review summarized the expression of microRNAs in RB and the related mechanism.

As children are extremely sensitive to the bad taste of medicine,they have poor compliance with the bitter medicine.It is of great importance to develop the approaches of taste masking for the research of paediatric drug formulations.Besides,taste masking technology is one of the main barrier to develop children pharmaceutic preparation.This article provides an overview of the advance in taste masking technology of oral paediatric medicine in recent years,and introduces five types of taste masking technology in terms of drug,preparation and the bitter taste transduction,including principle and characteristics of these approaches,as well as their application in formulations,so as to provide some references for the development of paediatric medicine.

ObjectiveTo investigate the mechanisms of N-acetylcysteine protection against liver injury caused by biliary tract obstruction in rats. MethodsSeventy-two Wistar rats were divided randomly into the following three groups: (1) Rats received choledochus ligationon and N-acetylcysteine by intraperitoneal injection (DBL+NAC); (2) Rats received choledochus ligationon only; (3) sham operation. Six rats were killed each time after 1 d, 3 d, 5 d and7 d and their liver function was tested by TBA-40FR Automatic Chemistry Analyzer. In addition, NO production was detected by Griess Reagent System. ResultsWhen the period of biliary duct obstruction is extended, serum AST,ALT,TBIL, DBIL, NO and TNF-α increase but the increase in serum ALT,AST,NO and TNF-α(P＜0. 05) is more prominent in group DBL than group DBL+NAC at any given time. Conclusions N-acetylcysteine can effectively protect against liver injury in rats with obstructive jaundice, and this may be achieved through down-regulation of TNF-α and NO in hepatocytes.

Objective To investigate the relationship between single nucleotide polymorphism (SNP) of Fas ligand (FasL) and fulminant hepatitis B in Han Chinese. Methods HBV infected subjects were enrolled in this case-control study, including 233 cases of inactive HBsAg carrier, 68 patients with fulminant hepatitis B,100 cases of spontaneous hepatitis B clearance, 102 patients with hepatitis B virus (HBV) related cirrhosis and 112 patients with HBV related primary hepatocellular carcinoma. The blood samples and clinical data were collected. FasL-844T/C polymorphisms of enrolled subjects were examined by TaqMan real time fluorescent genotyping polymerase chain reaction (RT-PCR). A adjusted odds ratios (OR)and 95% confidence intervals (CI)were calculated using the Logistic regression model. Results After adjusting the factors of gender and age, binary Logistic regression analyses indicated that the genotype frequencies of FasL-844 CC,CT,TT in inactive HBsAg carriers were 50. 64% ,39. 91% and 9. 44% respectively, and those in cases of fulminant hepatitis B were 79. 41%, 17. 65% and 2. 94%, respectively. The analysis also revealed that FasL-844CC genotype in inactive HBsAg carriers was high risk factor of developing fulminant hepatitis B (OR =4. 729,95%CI:0. 510 - 21. 282,P = 0. 043), while there were no statistic significances in other cases (P>0. 05). Conclusion The inactive HBsAg carriers harboring FasL-844CC may have greater susceptibility to fulminant hepatitis B, which need arouse high attention.

Objective To summarize the experiences in laparoscopic inguinal hernia repairing for adult patients. Methods Clinical data of 512 hernia cases admitted in our center from March 2007 to Sep 2010 were retrospectively analyzed.There were 437 cases of single-sided hernia,including 281 indirect inguinal hernia,86 direct inguinal hernia,15 femoral hernia,16 combined inguinal hernia and 39 recurrent hernia.There were also 75 cases of double-sided inguinal hernia,including 3 recurrent hernia.There were 41 acute incarcerated hernia cases.The average postoperative follow up time was(29 ± 12) months. Results 507 cases underwent successful laparoscopic repair,and 5 cases were converted to open procedure.There were 238 TAPP and 269 TEP in laparoscopic operations.The average operative time for TAPP was (69 ±19) min,and (58 ±15) min for TEP.The average length of postoperative stay was (5.0 ± 1.5) days.The percentage of resuming normal activity after 2 weeks and 4 weeks were 95.7％ (485/507) and 99.0％(502/507).The most common postoperative complications were seroma (9.7％,49/507),transient paresthesia (4.1％,21/507) and chronic pain (0.8％,4/507).The recurrence rate was 0.6％ (3/507).Conclusions Laparoscopic repair of inguinal hernia has the advantage of less trauma,faster recovery,and lower recurrence rate.
