[Variation in Phosphorus Concentration and Flux at Zhutuo Section in the Yangtze River and Source Apportionment].

Phosphorus (P) is a pollutant of great concern in the Yangtze River Basin. The Xiangjiaba Reservoir and Xiluodu Reservoir on the lower reach of the Jinsha River began to operate in 2012 and 2013, respectively, which greatly changed the concentrations of suspended sediment and characteristics of P form and transport in the reservoirs and the downstream reach from Yibin to Jiangjin of the Yangtze River. The Zhutuo section is representative in the water quality of the Yibin-Jiangjin reach, which can not only reflect the comprehensive effects of the formation of the two reservoirs and changes in the aquatic environment in the Min-Tuo Rivers but also reflect the quality of water flowing into the Three Gorges Reservoir.

Inhibition of autophagy enhances the radiosensitivity of nasopharyngeal carcinoma by reducing Rad51 expression.

Radiotherapy has long been considered as the mainstay of treatment for nasopharyngeal carcinoma (NPC). However, locoregional recurrence or distant metastasis may occur in some patients due to the radiation resistance of cancer cells. Autophagy plays a vital role in protecting cells against radiation.

[Study on treatment of simulant dairy processing wastewater using FCR multilevel contact oxidation system].

This study applied new helical-fibrous fillers as carrier to treat simulant dairy industrial wastewater in order to improve the ability of nitrogen removal and decontamination. Based on multilevel oxidation system where the food chain was formed by different kinds of microbe, removal ratio and removal mechanism of COD, TN, NH4+ -N, TP under different HRT and effect of sludge reduction were discussed. When COD of influent was 842-1843 mg/L, TN concentration was 36.

[Phase II clinical trial of home-produced Nedaplatin in treating advanced esophageal carcinoma].

Background & Objective: Nedaplatin is a second-generation anticancer drug containing organic platinum. Clinical researches in overseas showed that Nedaplatin is an anticancer drug with broad spectrum and high efficiency, especially in treating esophageal carcinoma. But the therapeutic efficacy and toxicity of home-produced Nedaplatin in China are unclear.

[Treatment of mix gas containing butyl acetate, n-butyl alcohol and phenylacetic acid from pharmaceutical factory by bio-trickling filter].

The bio-trickling filter packed with ZX02 stuffing is used to treat the mix gases containing butyl acetate, n-butyl alcohol and phenylacetic acid(BBP), which are discharged from Penicillin workshop of Pharmaceutical Factory. The reactor was operated for 110 days to investigate the effect of influent load, retention time and spray water on the removal of BBP and the biodegradation characteristics. The reactor displayed preferential utilization of BBP, when the maximum influent load of BBP were 229.

[Phase II clinical trial of nedaplatin in advanced non-small cell lung cancer].

Background & Objective: The aim of this study was to observe the efficacy and the side effects of nedaplatin in treatment of non-small cell lung cancer (NSCLC).

Methods: This is a multi-center phase II clinical trial. The previously chemotherapy treated patients with NSCLC were administrated nedaplatin alone.
