ObjectiveThrough the study of cervical lesions vagina inmage to investigate the micro-syndrome identified methods for cervical lesions. MethodsThrough the methods of retrospective study, collecting cases of HR-HPV infection (HC Ⅱ positive) and colposcopy detection, the objective evaluation of micro-syndrome differentiation was primarily established. ResultsRGB mode quantitative analysis for colposcopy images showed category 3 (the purple samples) occupied 44.4%, category 2 (the red samples)occupied 12.6%; category 1 (the white samples) occupied 43%. ConclusionsRGB mode quantitative analysis for colposcopy images was appropriate exploration of micro-differentiation in cervical lesions. There is a close relationship between traditional Chinese medicine syndrome and mucosai color differentiation by colposcopy.

Objective To discuss the effect of Qingdushuan on SiHa cells of cervical cancer proliferation and protein expression in PTEN-MDM2-p53 network from the level of cell biology and molecular biology. Methods SiHa cells were cultivated with 4% containing serum. Normal control group, blank serum group, Qingdushuan group, Baofukang group and interferon group were established. The influence of inhibiting and proliferating SiHa cell was detected by MTT assay. Three protein expression was detected by Western blot method. Results After cultured with drug containing serum, the number of cells decreased, 4% concentration of serum for 72 h was the strongest. Compared with the control group, there were significant differences (P
5. Research and application of non-clay low damage temporary bridging drilling/completion fluids system
Academic Journal of Xi'an Jiaotong University 2009;21(3):176-183
Following the basic theory of protecting gas-reservoirs from damage with the temporary bridging technology, inert calcium carbonate (CaCO3) particles, whose diameter is consistent with the size of pores or apertures in the reservoir, were selected as the bridging agent, and modified resolvable starch was selected as filtration loss reducing particles to form the non-clay low damage temporary bridging drilling/completion fluids system (NLTDFS). Under the simulated condition of the well bottom during real drilling, NLTDFS was used to conduct dynamic and static damage experiments of cores for 48 hours, respectively, and then the experimented cores were permeated with pure nitrogen from the undamaged end to the damaged one to measure their recovery of permeability. The results showed that the permeability recovery rate of the core reached 90% or so, and the damaged depth was less than 1 cm, which demonstrates that NLTDFS has higher temporary bridging effectiveness and lower damage to the gas-reservoir than other drilling fluids system. NLTDFS has been used to drill many horizontal wells, and four of them have obtained high yield of natural gas. The yield of natural gas of LP1 well reached 85 × 104 m 3/day after completion with the rump pipe. The formation of the stable well wall and smooth drilling led to an API loss less than 4 mL and an HTHP loss less than 15 mL.
