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

OBJECTIVE:To study the chemical constituents of Zingiberis Rhizoma.METHODS:The compounds of Zingiberis Rhizoma were classified and purified by silica gel,Sephadex LH-20 column chromatography and thin layer chromatography (TLC).The structure of compounds were analyzed and identified according to chemical property and spectrum data.RESULTS & CONCLUSIONS:Five compounds were isolated from Zingiberis Rhizoma,i.e.methyl-6-gingerol (1),4-gingerol (2),β-eudesmol (3),2,5-dihydroxybisabola-3,10-diene (4),6-shogaol (5).The compounds 2,3,4 are isolated from Zingiberis Rhizoma for the first time.

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.

Objective To evaluate the changes in plasma S-100β protein concentration in patients undergoing cardiac surgery performed with cardiopulmonary bypass (CPB).Methods ASA Ⅱ or Ⅲ patients aged 60-77 yr weighing 55-75 kg with national institutes of health stroke scale(NIHSS) ＜ 10 undergoing coronary artery bypass grafting with CPB were enrolled in this study.Cerebral function was evaluated and scored using NIHSS at 2 d after operation.The patients were divided into 3 groups according to NIHSS scores:group A uncomplicated (NIHSS score 0-9),group B mild brain injury (NIHSS score 10-19) and group C moderate and severe brain injury (NIHSS 20-45).Plasma S-100β protein concentration was measured before CPB,at 30 min of CPB,the end of CPB and 1 h,6 h,24 h after CPB.The duration of operation,CPB time,aortic cross-clamping time and length of ICU stay and hospital stay were recorded.Results Ten patients in groups A and B and 12 in group C completed the trial.Plasma S-100β protein concentration was significantly increased during and after CPB as compared with the baseline at T0 and peaked at T3 (groups A,B) and T4 (group C).The plasma S-100β protein concentration was highest in group C and lowest in group A.The duration of operation,CPB time,aortic cross-clamping time and length of ICU stay and hospital stay were longest in group C and shortest in group A.Conclusion Plasma S-100β protein concentration can be used as a marker of cerebral injury after cardiac surgery performed with CPB and the concentration measured at 6 h after CPB is more significant in evaluating the degree of cerebral injury and prognosis.
