This study is to investigate the anti-tumor activities of a novel cyclophosphamide derivate 4, 6-diphenyl cyclophosphamide (9b) in vivo and in vitro, and its possible mechanism of action. The inhibitory effects of 9b on human hepatoma cell line HepG2, human breast carcinoma cell line MCF-7 and human myeloid leukemia cell line K562 were measured by MTT assay in vitro. Cell cycle distribution and apoptotic rate were evaluated by flow cytometry. To evaluate the anti-tumor effect of 9b in vivo, mouse model bearing inoculated H22 tumor was established. The results indicated that 9b could inhibit the proliferation of HepG2, MCF-7 and K562 cells in a dose and time dependent manner. The ICo50 values of 9b were 32.34 micromol.L-1 to HepG2 cells, 87.07 micromol.L-1 to MCF-7 cells and 149.10 micromol.L-1 to K562 cells after incubation for 48 h. The results of flow cytometry indicated that after being treated for 48 h with different concentrations of 9b, the ratios of HepG2, MCF-7 cells at the Go/G1 phase and K562 cells at the G0/Gl phase and G2/M phase increased significantly compared with control group, and the apoptotic rate increased with the increase of the concentration of 9b. 9b could significantly reduce tumor weight of H22 solid tumor mouse model in vivo. To summarize, 9b showed significantly anti-tumor activity in vivo and in vitro, of which the mechanism might be associated with the change of cell cycle distribution and induction of tumor cell apoptosis.

OBJECTIVETo explore the protective effect and mechanism of total flavones of Bidens pilosa L. (TFB) on IgA1 induced injury of venous endothelial cells in Henoch-Schönlein purpura (HSP) children patients. METHODS Human umbilical venous endothelial cells (HUVECs) were taken as subject. They were intervened by normal IgA1 and HSP children patients' serum IgA1, and added with different concentrations TFB at the same time. Then they were divided into the blank control group, the normal control group, the HSP IgA1 group, and HSP IgA1 plus TFB (1.0, 0.5, 0.25 mg/mL) groups. Levels of TNF-α and IL-8 in supernate were detected by ELISA. The NO level was detected by nitrate reductase method. mRNA and protein expressions of NF-κB and ICAM-1 in HUVECs were detected by fluorescent quantitative PCR and Western blot respectively.

RESULTSCompared with the normal control group and the blank control group, levels of IL-8, TNF-α, and NO all significantly increased in the HSP group (P < 0.05). Compared with the HSP group, levels of IL-8, TNF-α, and NO significantly decreased after intervention of TFB (1.0 and 0.5 mg/mL; P < 0.05, P < 0.01). Results of fluorescent quantitative PCR and Western blot showed, as compared with the blank control group and the normal control group, mRNA and protein expressions of NF-κB and ICAM-1 in HSP children patients' serum IgA1 induced venous endothelial cells significantly increased with statistical difference (P < 0.05, P < 0.01). Compared with the HSP group, mRNA and protein expressions of NF-KB and ICAM-1 were obviously down-regulated after intervention of TFB (1.0, 0.5, 0.25 mg/mL), with statistical difference (P < 0.05, P < 0.01).

CONCLUSIONTFB could protect vascular damage by inhibiting in vivo high expression of NF-κB, reducing the production of IL-8, TNF-α, and NO in vascular endothelial cells of HSP children patients.

There were statistical differences of vision of the two groups before and after treatment (P<0. 05), and there were no statistical differences of the two groups between the two groups after treatment (P>0. 05). The cornea, sclera, wound healing time of the observation group were less than the control group, and there were statistical differences between the two groups ( P < 0. 05 ). The incidence of complications was 13. 8% in the control group and 3. 2% in observation group, with statistically significant difference (P<0. 05).
CONCLUSlON: The application effect of microscopic pterygium resection combined with MMC is remarkable, and the joint of 0. 2mg/mL concentration of MMC is more safe and effective, and is worth popularizing in clinical application.

Objective To investigate the iodine nutritional status of targeted population in the high-risk areas of iodine deficiency disorders in Chongqing, so as to provide scientific evidence for establishing prevention and remedial measures. Methods Six towns were selected in Chengkou and Wuxi Counties to found suspected dementia patients born after first Jan, 1997. Two hundred children aged 8-10 years were investigated in every town. The thyroid volume, intelligence quotient(IQ) and urinary iodine of the children were examined. Forty women (pregnant and nursing women) were investigated in every town. The iodine content of salt from their home was measured. The thyroid volume was examined by palpation and B-uhrasound. IQ was measured by combined Raven Test in China(CRT-RC2). Urinary iodine was determined using the acid digest arsenic-cerium contacting method, and iodined salt was detected using direct titration method. Results Six suspected dementia patients were found in the local town hospital. Five eases were excluded. There was 1 case born in other place. The rates of goiter by palpation and B-ultrasound were 9.58%(92/960) and 8.89%(65/731), respectively. The median of urinary iodine of children and women was 319.15 μg/L and 248.42 μg/L, respectively. The mean of IQ of the children was 103.32. The coverage rate of iodine salt from residents was 98.82%(336/340). Conclusions The iodine nutrition of children was good and there is no newly occurred cretinism in Chengkou and Wuxi Counties. Goiter rate and median of urinary iodine aged 8-10 years and of women, coverage rate of iodine salt from resident has meet the standard set for basical elimination iodine deficiency disorders.

The value of adding induction chemotherapy (IC) to concurrent chemoradiotherapy (CCRT) for the treatment of locoregionally advanced nasopharyngeal carcinoma (NPC) remains unclear. In our recent article entitled “Induction chemotherapy plus concurrent chemoradiotherapy versus concurrent chemoradiotherapy alone in locoregionally advanced nasopharyngeal carcinoma: a phase 3, multicentre, randomised controlled trial” published in theLancet Oncology, we reported the results of a phase III, multicenter, randomized controlled trial comparing cisplatin, 5?lfuo?rouracil, and docetaxel (TPF) IC plus CCRT versus CCRT alone in patients with T3?4N1/TxN2?3M0 NPC (ClinicalTrials.gov registration number NCT01245959). The IC?plus?CCRT group showed signiifcantly higher 3?year failure?free survival, overall survival, and distant failure?free survival rates than the CCRT?alone group, with an acceptable toxicity proifle. Our study suggests that adding TPF IC to CCRT could increase survival rates and reduce distant failure in patients with locoregionally advanced NPC. However, long?term follow?up is required to assess the eventual effcacy and toxicity of this strategy, and a more accurate method to determine prognosis is needed to enable better tailoring of treatment strategy for individual patients.

Objective To study the characteristics of work disability and its influencing factors in patients with ankylosing spondylitis (AS). Methods The demographic data, work conditons and disease related characteristics of 277 patients with AS were recorded, and randomly selected from the Department of Rheumatology, Chinese PLA General Hospital from November 2014 to January 2016. Work and productivity activity impair-ment questionnaire (WPAI) was used to survey the work disability and productivity loss, then explore its in-fluencing factors and the relationships between patient-reported outcomes and WPAI scores. Logistic regression was used to analyze the associated factors of work disability. Multivariate linear regression was used to analyze the predictive factors of lose of work productivity. Results The prevalence of work disability was 30.3%. Twenty patients were unemployed because of working disability. Two hudreds patients were employed, with average 36.5 (24.0, 50.0) hours workingtime in the past week. Average AS related absenteeism was 4.4 (0, 10) hour. Average workproductivity loss was 26.4%(2.5%, 40.0%). Logistic multiple regression analysis showed that Bath AS disease activity index (BASDAI), SF-36 physical component summary (PCS) scores might be the important influencing factors among those clinical measures ( OR=1.270, 0.959). Presenteeism and overall work impairment were moderately correlated with patients' global assessment of disease activity (VAS), BASDAI, bath AS functional index (BASFI), SF-36 physical Functioning (PF), SF-36 body pain (BP) and SF-36 Physical Component Summary (PCS) (|r|=0.539-0.648). Linear multivariate analyses indicated that work presente-eismand absenteeismwere significantly associated with BASDAI (P<0.01). Conclusion High prevalence of work disability in patients with AS is noted, which is closely related with disease activity and body function;High attention should be paid to AS patients with work disability.
