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 report a case of Majocchi's granuloma induced by var. raubitschekii of Trichophyton rubrum, and to evaluate the relationship between deep and superficial fungal infection with genotyping technique. Methods The patient underwent physical, pathological and mycologic examination,which included microscopic observation, fungal culture, and urease reaction. The sequence of intertranscribed spacer (ITS) of rDNA was analysed by PCR and sequencing. Isolates from affected toes and tissue as well as one reference strain and six clinical strains of T. rubrum, were subjected to analysis of the tandem repeat subelement(TRS-1) in nontranscribed spacer(NTS)of rDNA by PCR. Results A 48-year-old female patient presented with a 2-month history of red papules and nodular lesions on the back, buttock and thigh,as well as a 3-year history of onychomycosis which had become more severe after a liver transplantation 9 months before. Pathological and mycologic examinations confirmed the diagnosis of Majocchi's granuloma. The pathogen was identified as var. raubitschekii of T. rubrum by microscopic examination, fungal culture, positive urease reaction and the sequence of ITS. As shown by the amplications of TRS-1 of NTS, the genotypes of strains from affected nails and tissue were identical, but differed from those of other clinical strains of T.rubrum. Conclusions There is a polymorphism in TRS-1 of rDNA NTS of T. rubrum, with the genotypes of isolates from affected nails and tissue being identical, which suggests they are of the same origin.

Objective To investigate the accuracy of myeline base protein (MBP) in evaluation of brain injury in patients undergoing cardiac surgery performed under CPB. Methods Thirty-two ASA Ⅱ- Ⅳ patients of both sexes (20 males, 12 females) aged 59-76 yr weighing 52-72 kg undergoing coronary artery bypass grafting (CABG) under CPB were studied. Patients with history of neurological disease were excluded. Preoperative National Institute of Health stroke scale (NIHSS) score ≤ 9. According to postoperative NIHSS score on 2nd postoperative day, the patients were divided into 3 groups: group A no neurological deficit ( NIHSS score 0-9 );group B mild neurological deficit (NIHSS score 10-19) and group C moderate or severe neurological deficit (NIHSS score 20-45). Blood samples were taken from internal jugular vein before CPB (T0), at 30 min of CPB (T1), at the discontinuation of CPB (T2), and at 1, 6, 24 h after discontinuation of CPB (T3-5) for determination of the plasma MBP concentration. The duration of operation, CPB time, aortic cross-clamping time were recorded.Results In group B the plasma MBP level peaked at 6 h after CPB (T4) and then decreased rapidly while in group C the plasma MBP level exceeded the normal upper limit at T2 and kept increasing till 24 h after CPB (T5 ).The plasma MBP level decreased at T1-3.5 in group A as compared with the normal upper limit. The plasma MBPlevel was significantly higher at T3-5 in group B and at T1-5 in group C than in group A and at T1-5 in group C than in group B. Linear regression analysis indicated that there was positive correlation between plasma MBP level and CPB time at T5. NIHSS scores were positively correlated with plasma MBP level at T1 , T2, and T5. Conclusion MBP can early reflect the severity of brain injury in patients undergoing cardiac surgery under CPB.
