Nowadays,one of the most challenging aspects of retinoblastoma (RB) therapy is how to control the resistant or recurrent viable vitreous seeds,for which intravenous chemotherapy appears to be ineffective.Recently,intravitreal chemotherapy offers another option to control advanced stage and vitreous seeds of RB,and may be a promising new approach to RB therapy.However,intravitreal injection for RB patients raises considerable controversy due to concerns of possible extraocular extension along the injection route,and should not replace the primary standard of care for bilateral RB or group E eyes of RB.Close follow-up and further studies are needed to determine appropriate indications,to determine the effective drugs and concentrations,to optimize RB therapy protocols and to investigate the relationship between long-term efficacy and toxicities.

Objective The purpose of this study was to examine the relationship between acute mountain sickness ( AMS) and AMS susceptibility indices before ascent to high altitude and to evaluate their predictive value for AMS. Methods A total of 314 healthy male a-dults were voluntarily enrolled. Their 22 physiological and mental indices of AMS susceptibility were obtained before exposure high altitude. The diagnoses of AMS were based on the Lake Louise score ( LLS) ,an international standard scoring system for AMS. According to the char-acteristics of selected AMS susceptibility indices and the strong fault tolerance of neural network theory, the learning vector quantization ( LVQ) neural network method was adopted to build the prediction model of susceptibility to AMS. Results The results showed the sensitiv-ity of the LVQ model which distinguishes subjects with no-AMS reached 95. 00%,the average correct-prediction precision ultimately reached 72. 22%. The result of prediction is believable. Conclusion The builded LVQ model provide a scientific method for screening crowd who quickly ascend to high altitude,and also can lead to an effective preliminary screening of susceptibility to AMS.

Objective To study the effects of di-butyltin dilaurate (DBTD) exposure on pregnancy outcome in Wistar rat and evaluate it's effect on sexual development of fetuses. Methods Timed pregnancy rats were treated with corn oil or DBTD (10, 20, 30 mg/kg body weight) from days 12-19 of gestation. On gestational day (GD) 20, dams were sacrificed to investigate the pregnancy outcome. Results There was a downtrend in weight of dams on GD20 as the DBTD exposure dose increased. The weight of dam's utero significantly decreased in 30 mg/kg group. A significant decrease in fetal weights was observed in all DBTD groups, and fetal sizes in 20, 30 mg/kg groups. Exposure to DBTD from GD 12-19 resulted in a distinct increase in normalized anogenital distances in female fetuses, but no effects were seen in male ones. DBTD exposure did not result in external malformations, however, delayed ossification of fetal phalanges was observed in all DBTD treated groups. Dead fetuses and absorbed embryos were observed in 20, 30 mg/kg DBTD groups. Conclusion The results of the present paper show that DBTD exposure has some adverse effects on fetal development and may exert a masculinizing effect on female fetuses.

Objective: To compare the different therapeutic effects of acupuncture and Phenolphthalein for constipation due to intestinal qi stagnation. Methods:A total of 50 patients with constipation due to intestinal qi stagnation were randomly divided into an acupuncture group and a medication group by the random digital table, 25 cases in each group. The patients in the acupuncture group were treated by puncturing Gongsun (SP 4), Sanyinjiao (SP 6), Taichong (LR 3), Zusanli (ST 36), Shangjuxu (ST 37), Hegu (LI 4), Lieque (LU 7), and Tianshu (ST 25), once every day, and 7 d as one course, for continuous 3 courses; while the patients in the medication group were given Phenolphthalein, 7 d as one course, for continuous 3 courses. Compared the Cleveland clinic constipation score (CCS) between the two groups after one course, 3 courses and 3 months after the treatment, as well as the frequency of defecation within one week. Results:After one week of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significantly in the patients of the medication group than in those of the acupuncture group (P<0.01). After 3 weeks of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significant in the patients of the acupuncture group than in those of the medication group (P<0.05). Three months after the end of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significantly in the patients of the acupuncture group than in those of the medication group (P<0.05). Conclusion:Acupuncture and medication are effective in the treatment of constipation due to intestinal qi stagnation. Their short-term therapeutic effect is similar, but the long-term therapeutic effect is better in the acupuncture group than in the medication group.
