Erectile dysfunction(ED) is a common condition in men from 40 to 70 years of age,and during the last decades intensive research has highlighted clinical practice and public sectors.The development of Sildenafil,Vardenafil and Tadalafil have made the first class of agents capable of treating ED with convenient oral administration available.In the past years intracavernosal and intraurethral agents have been developed,but their clinical use was limited due to its invasiveness,and with high discontinuation rates.Gene therapy will be an effective method in future.

BACKGROUND: A great deal of free radicals can be induced,which results in peroxidation of the whole body. The antioxidant activity and the abilities of scavenging free radicals of proanthocyanidins(GSP) have been well documented,but related researches about the protective role in radiation damage were less reported.OBJECTIVE: To investigate the protective role of GSP combined with casein in 60Co-y radiation-induced peroxidative damage.DESIGN: Observing and comparative study based on animal model.SETTING: Nutrition Department of Daping Hospital Affiliated to the Third Military Medical College of Chinese PLA.MATERIALS: This study was carried out in the Third Institution of Field Operation Surgery, the Third Military Medical College of Chinese PLA.Eighty healthy Wistar rats,clearage,were adopted,ith weight from 180 to 220 g,half male and half female were adopted.METHODS: Rats were divided into four groups: normal control group,irradiation group,GSP group and GSP + casine group with 20 rats each. Rats in GSP group were fed routinely and supplemented with 1% GSP for 10days,which was replaced by 1% GSP and 5% casein. All rats except those of control group were exposed to whole-body 60Co-g amma-radiation at a dose of 7 Gy. Seven days later,6 survival rats randomly selected from each group were killed.MAIN OUTCOME MEASURES: The level of serum malondialdehyde (MDA), activities of serum superoxide dismutase(SOD),spleen index and the number of peripheral white blood cell(WBC).RESULTS: Serum MDA was obviously increased,accompanied by obviously attenuated SOD activity after irradiation; the level of MDA in both GSP group and combined group was found lower than that in irradiation group with statistical significance between them(P<0.01), the activity of SOD was significantly higher than that of irradiation group(P<0.01 ) . Markedly atrophic pathological change in spleen could be observed in irradiated rats,and meanwhile spleen index declined with the number of WBC notably decreased. But spleen index in both GSP group and combining group was markedly higher than irradiation group(P<0.05),and the same comparing result could also be found in the number of WBC(P<0.01 ).CONCLUSION: Peroxidative impairments could be obviously attenuated,and decrement of WBC could also be improved by single GSP or alternatively GSP combined with casein,with the latter showing greater effects in respect of improving immune function following irradiation,cellular chemical imbalance,and consequently the life quality.

Idiopathic thrombocytopenic purpura (ITP),as a heterogeneous autoimmune disease,is the most common bleeding disorder,of which etiology and pathogenesis are still unclear. Health related quality of life are severely affected,especally in chronic patients . Studys on chronic idiopathic thrombocytopenic purpura pathogenesis ,both in China and abroad,have found that genetic factors may be involved in the occurrence and prognosis of the disease. The paper gives a review from the follow aspects,such as its risk factors,relationship between genetic polymorphisms or expression levels and chronic ITP susceptibility and seriousness,the role of epigenetic,researchs about chronic and refractory ITP,et al.

Objective:To explore the effect of sodium cantharidate vitamin B6 injections in the adjuvant treatment of advanced cer-vical cancers. Methods:Totally 60 cases of advanced cervical cancer patients were randomly divided into the observation group and the control group, and the control group was given common DP chemotherapy and radiotherapy, while the observation group was given sodium cantharidate vitamin B6 injections additionally. After the 6-week treatment, the short-term curative effect, bone marrow inhibi-tion adverse reaction, immune function and life quality were compared between the two groups. Results:The short-term curative effect in the observation group was 66. 7%, which was significantly higher than that in the control group (40%)(P<0. 05). The degree of adverse reaction was significantly lower than that in the control group with statistical significance (P<0. 05). After the treatment, CD8 +, NK cells and CD8 + / CD4 + in the two groups were significantly improved, and those in the observation group were all better than those in the control group (P<0. 05). The improvement of life quality in the observation group was more notable than that in the control group with statistical significance (P <0.05). Conclusion: Sodium cantharidate vitamin B6 injections can significantly in-crease the short-term curative effect and immune function, decrease bone marrow inhibition and improve life quality of advanced cervi-cal cancer patients.
