AlM:To investigate the features on prolonged central serous chorioretinopathy ( CSCR ) by optical coherent tomography ( OCT ) and to provide the basis of deciding the pathogenetic condition and prognosis. METHODS: Eighty - five patients who had been diagnosed with CSCR were grouped by suffering time as below: 32 patients suffered longer than 6mo as the prolonged and 53 patients with CSCR cured within that time. The imaging features of OCT were compared between the above groups.RESULTS:The incidence rate of neuroepithelial serous detachment extent above 500μm associated with pigmentary epithelial detachment in suffering eye and pigmentary epithelial damage in contralateral eye was significantly different between two groups. However, the incidence rate of neuroepithelial serous detachment extent above 4 000μm was not significant difference.CONCLUSlON:OCT could display clearly the change of every layer of retina with simplicity and visibility, which supplies us a new horizon to diagnose and trace CSCR. We could decide the pathogenetic condition and prognosis in accordance with the features of OCT, to provide references for the diagnosis and treatment of CSCR.

The purpose of the study is to construct R8 peptide (RRRRRRRR) and pH sensitive polyethylene glycols (PEG) co-modified liposomes (Cl-Lip) and utilize them in breast cancer treatment. The co-modified liposomes were prepared with soybean phospholipid, cholesterol, DSPE-PEG2K-R8 and PEG5K-Hz-PE (pH sensitive PEG). The size and zeta potential of Cl-Lip were also characterized. The in vitro experiment demonstrated that the Cl-Lip had high serum stability in 50% fetal bovine serum. The cellular uptake of Cl-Lip under different pre-incubated conditions was evaluated on 4T1 cells. And the endocytosis pathway, lysosome escape ability and tumor spheroid penetration ability were also evaluated. The results showed the particle size of the Cl-Lip was (110.4 ± 5.2) nm, PDI of the Cl-Lip was 0.207 ± 0.039 and zeta potential of the Cl-Lip was (-3.46 ± 0.05) mV. The cellular uptake of Cl-Lip on 4T1 cells was pH sensitive, as the cellular uptake of Cl-Lip pre-incubated in pH 6.0 was higher than that of pH 7.4 under each time point. The main endocytosis pathways of Cl-Lip under pH 6.0 were micropinocytosis and energy-dependent pathway. At the same time, the Cl-Lip with pre-incubation in pH 6.0 had high lysosome escape ability and high tumor spheroid penetration ability. All the above results demonstrated that the Cl-Lip we constructed had high pH sensitivity and is a promising drug delivery system.

According to the requirement of simulated actual combat,based on the traditional contents of sanitary reconnaissance of water source,this paper introduced some practical knowledge and skills in drinking water under emergency,including water source search,utilization,drinking principles and some measures to reduce the loss of body water.These practices enriched and consum- mated the subject of sanitary reconnaissance of water source.

Objective To find the dominant bacteria in mountain-lake water which can inhibit the alga growth by separation, culture,identification.Methods The samples from the lake in Simian Mountain area,Chongqing were collected.Bacteria- increasing culture,separation and identification were conducted to choice the dominant bacteria.With the dominant bacteria,the ecological restoration was conducted in the eutrophicated water in laboratory,the growth of alga was observed and the water quality was determined.Results Citrobacter freundi,Pseudomonas mendocina,Aeromonas veronii,Achromobaeter xylosoxidans were the dominant bacteria in the lake in Simian Mountain area,Chongqing.Compared with the blank water eontrol,the algae growth speed was slower,COD_(Mn)was 7.1 and 7.4 mg/L respectively,the chroma was both 20 degree in the experimental water samples with Citrobacter freundii and Pseudomonas mendocina.Conclusion The algae inhibitory action of Citrobacter freundii and Pseudomonas mendocina in the mountain lake water is obvious.
