Hodgkin lymphoma (HL) is a rare subtype of B-cell malignancies, and it often occurs in the youth. About 80 % patients can be cured with the advance of modern therapy. How to further improve the cure rate of HL and minimize adverse reactions are new tasks faced by the clinicians, meanwhile, short-term curative effect and long-term survival rate are worthy of attention. An accurate assessment of disease stage is crucial for the selection of the appropriate therapy. This review discusses the hot issues regarding HL treatments to further improve the precision therapeutics, and to provide more references for clinical treatment.

Objective To construct the autocatalytic caspase-3 and investigate its apoptosis- inducing effect in ovarian cancer in vitro and in vivo.Methods PCR recombination technique was used to construct autocatalytic caspase-3 which is named as rev-caspase-3,and Ad-Max system was used to prepare recombinant adenovirus containing rev-caspase-3,which is named as Ad-rev-easp3.Immunohistochemistry was used to detect active caspase-3 expression.Cell counting kit,flow cytometry and western blot were used to measure cell survival rate,apoptotic rate,cell cycle distribution and the expressions of plT,active subunit of caspase-3,and p85,the poly(adenosine diphosphate-ribose)polymerase(PARP)cleavage segment,respectively.Transmission electron microscope was used to detect cell ultrastrueture,and real time PCR was used to detect apoptosis-related gene expression.Subcutaneous tumor models and abdominally spread tumor models of human ovarian carcinoma were established using AO cells in BALB/c nude mice. The mouse survival rates were measured for abdominally spread tumor models,and the volume of tumor nodules were determined for subcutaneous tumor models following the treatments of rev-caspase-3.Results Active caspase-3 protein was significantly expressed,and the expression levels of active subunit of caspase- 3,p17,and the PARP cleavage segment,p85,were significantly elevated in cells treated with rev-caspase- 3.The decrease of cell survival rate and the increase of cell apoptotic rate were detected following Ad-rev- casp3 treatment.Treatments with Ad-rev-casp3 [ multiplicity of infection(MOI)was 70 ] resulted in survival rate of 30.3% and apoptotic rate of 40.2%.There was a significant increase in cell number of S- phase(56.5%),while there was no significant apoptosis(3.4%)following treatments with Ad-rev-casp3 at a low dosage of MOI=10.Cells treated with rev-caspase-3 displayed significant apoptotic morphology. The levels of active caspase-3 gene expressions(9.44)significantly increased.Rev-caspase-3 treatment significantly prolonged survival,the mean survival duration was(213?16)days,and suppressed tumor growth(tumor growth suppression rate was 70%),when compared with treatment with phosphate buffered saline(PBS).Conclusion Recombinant adenovirus containing rev-caspase-3 can significantly induce apoptosis of ovarian carcinoma cells,suppress tumor growth and prolong the mouse survival duration.

Takayasu arteritis (TA) is a devastating vasculitis of the aorta and its major branches,coronary and pulmonary arteries.The clinical manifestations in children are less specific than in adnlts:the disease in children presents with fever,arthralgias,vomiting,weight loss and hypertension.Conventional angiography,which is recognized as the golden standard in evaluating vascular lesions in TA,combined with computer tomography angiography (CTA),magnetic resonance angiography (MRA),ultrasonography,could not only provide important information for early diagnosis,but also detect disease activity.New immunosuppressive agents and biological therapies,such as TNF-a blocking agents,have been verified to be effective although corticosteroids and conventional immunosuppressive agents are still basic treatment.

Objective To study the expression and its significance of bcl-2 associated death (bad) gene in human optic nerves from traumatic atrophic eyeballs. Methods The optic nerves from 8 normal human donor eyes and 31 traumatic atrophic eyes were studied by immunohistochemistry technique. Results Bad protein was positively expressed in the normal optic nerve myelin sheath and residual myelin portions of optic nerve tissues from traumatic atrophic eyes. The expression of bad protein in the residual portions of myelin sheath was stained significantly stronger than that in normal optic nerves (P0 05). Conclusion Bad might possess the function of promoting the optic nerve atrophy processes in traumatic atrophic eyes.

As one of the serious complications of diabetes, diabetic retinopathy( DR) has become a main eye disease which causes blindness. The occurrence and development of DR is related to many factors. The pathogenesis is complicated, and the mechanism has not been clear. Early data suggest that the occurrence and development of DR has relations with many factors such as blood sugar level, diabetes duration and the environment. Among the factors, mitochondrial dysfunction and oxidative stress is the important mechanisms of DR and has become research focus in recent years. Consequences of mitochondrial dysfunction within cells include elevation of the rate of reactive oxygen species( ROS) production due to damage of electron transport chain proteins, mitochondrial DNA ( mtDNA ) damage, and loss of metabolic capacity. Clear understanding on the mechanism of mitochondrial functional change under high sugar level and oxidative stress response in the occurrence and development of DR is of great significance on prevention and cure of DR. ln this article, the development of mitochondrial metabolism and oxidative stress of DR is reviewed.

Objective To explore systematic intervention methods on life quality of heroin addicts during convalescence stage of drug detoxification period in order to supply evidence for effective nursing intervention. Methods 156 patients accorded with standard were selected by subjective sampling method and were grouped randomly. 78 patients in the control group were given routine nursing,78 patients in the intervention group received systematic intervention including psychological and behavioral intervention and the therapy of physical symptoms. QOLDA was used to evaluate the life quality of all patients. Results The scores of the intervention group were significantly higher than those of the control group, and the intervention group had a higher body mass index (BMI). Conclusions Systematic nursing intervention can perfect the physiological function, mental function and social function, reduce the withdrawal syndrome and adverse effect of heroin addicts, and improve their quality of life.
