50 000 bp)was extracted from frozen gastric cancer tissue and their corresponding normal samples and used for RLGS assay.The genome DNA was digested by methylation-sensitive restriction enzyme Not Ⅰ, and labeled by radioisotope ~(32)p,then separated by two-dimensional electrophoresis and autoradiography. Experimental conditions for each step were optimized step by step.DNA fragment sequences for the dots on scanning profile were identified according to the human RLGS database.Results RLGS assay was set up and used to get the RLGS profiles of the representative tested samples successfully.These profiles can display more than 1 200 available dots averagely,the profiles of high quality DNA sample can display more than 1 800 dots which is the average level at an excellent RLGS lab,discrepant dots which had weaken or enhanced signals and their sequence information were obtained.The result can be reproduced.Conclusion The RLGS assay is established,stabilized for detection of DNA methylation of tissue samples.

AIM:To establish an HPLC-ELSD method for determing dulcitol and astragaloside in Compound Fufangteng Capsules(Radix et Rhizoma Ginseng rubra,Radix Astragali,Herba Euonymi,etc).METHOD:Chro-matographic conditions included Lichrospher 5-NH_2 column(250 mm?4.6 mm,5 ?m)and the mobile phase consisting of a mixture of acetonitrile-water(91 ∶9).The flow rate of mobile phase was 1.0 mL/min.The column tempe-rature was at 28 ℃.Detector:PL-ELS2100 ELSD(Eva:65 ℃,Ned:50 ℃,gas flow:0.9 L/min).RESULTS:The linear ranges of dulcitol and astragaloside were 2.91-29.1 ?g(r= 0.999 8)and 1.03-10.3 ?g(r= 0.999 1),respectively.The average recoveries of dulcitol and astragaloside were 99.24% and 103.17% with corresponding RSD of 2.6 % and 1.8%(n=6),respectively.CONCLUSION:The method is steady and with good repeatability,and can be used to determine the content of dulcitol and astragaloside in Compound Fufangteng Capsules.

Objective To analyze the type of acid-base disturbance caused by severe pneumonia in newborn infants .Methods Venous blood of neonate with severe pneumonia(SP group) were collected to detect serum electrolyte and blood gas analysis 12 hours before and after oxygen therapy .The results of serum electrolyte and blood gas were compared 12 hours before and after oxygen therapy ,and the results of acid-base disturbance between SP group and control groups were compared.Results There were mostly metabolic acidosis incorporated respiratory acidosis in all neonate in SP group,which were with increased anion gap (AG) and obviously higher than that of control group(t=1.27 P

Objective To evaluate the relationship between damages of visual field and retinal nerve fibre layer(RNFL)thickness in primary open angle glaucoma(POAG)with high myopia.Design Retrospective,case-controlled study.Participants POAG group with high myopia(21 eyes of 17 cases),POAG group with non-high myopia(17 eyes of 16 cases),high myopia group without POAG(25 eyes of 20 cases)and normal control group(19 eyes of 17 cases).Methods The static central visual fields were tested with Humphrey 750 automated perimetry and thickness of RNFL was measured with optical coherent tomography(OCT).Main Outcome Measures Mean deviation(MD),pattern standard deviation(PSD)and mean sensitivity at upper,lower,nasal and temporal quadrants in total deviation probability plots.Thickness of RNFL at upper,lower,nasal and temporal quadrants.Results There were more obvious general depression of sensitivity in total deviation probability plots of the early POAG with high myopia than those of POAG without high myopia,and the early visual field defects of glaucoma in pattern deviation probability plots of this group.MD of POAG with high myopia was more than those of others(P＜0.05).The differences of MD,PSD and mean sensitivity between POAG with high myopia and others were significant(P＜0.05).Mean sensitivities in each quadrant of POAG without high myopia were similar to those of high myopia(P＞0.05).The thickness of RNFL of POAG with high myopia was thinner than those of others and the thickness of RNFL of normality was thicker than that of others.The correlationship between mean sensitivity and the thickness of RNFL in each quadrant was significant(P＜0.05).Conclusion Pattern deviation probability plots is an important favor for judgement of the visual field changes in POAG with high myopia.The relationship between RNFL thickness with OCT and visual field damage may provide clinically relevant information in diagnosis of POAG with high myopia

Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

Objective To assess the contractility of levator ani muscle in postpartum female using pelvic floor three-dimensional ultrasound and to provide an effective imaging basis for the change of levator ani muscle contractility in postpartum female.Methods Totally 75 postpartum women (55 underwent spontaneous vaginal delivery and 20 underwent selective cesarean delivery) and 40 nulliparas were examined by pelvic floor three-dimensional ultrasound.The images were obtained at rest and at maximal levator ani muscle contraction.The sagittal hiatal length (L) on the two-dimensional sagittal images,the area of levator hiatus (A) and the circumference of levator hiatus (C) were measured on the three-dimensional images,and the difference value between rest and contraction were calculated to get the △L,△A,△C.Then the △L,△A,△C between different groups were compared.Results The △L,△A,△C in spontaneous vaginal delivery group and selective cesarean delivery group were smaller than those in nulliparas group (P ＜0.05),and there was no statistical difference between spontaneous vaginal delivery and selective cesarean delivery group (P ＞ 0.05).Conclusions Three-dimensional ultrasound can effectively assess the the contractility of levator ani muscle,the levator ani muscle contractility of postpartum female was poorer than nulliparas,and between spontaneous vaginal delivery and selective cesarean delivery women there is no obvious difference.
