Objective:To probe the effect of Alisol Monoacetate A and Alisol Monoacetate B on the synthesis and metabolism of cholesterol in HepG2 cell line.Methods:Controlled with Lipitor,different concentration of Alisol Monoacetate A and B were added to HepG2 cell line model,then collected and detected the contents of cholesterol in the cell lysate and cultured medium after 24h's cultivation.Results:The cytotoxicity of Alisol Monoacetate A and B appeared at least 10% when its concentration was higher than 10?M,more than 70% when its concentration was 50?M.The contents of cholesterol in HepG2 cell lysate increased from 24.4,26.7,32.3 and 38.3?g/mg protein corresponding with the concentration of 0?M,3?M,10?M and 20?M respectively,which showed the positive dose-effect relationship.However,the contents of cholesterol in the cultured medium manifested no difference.Conclusion:Alisol Monoacetate A and B could enhance the metabolic activity of mitochondria and increase the synthesis of cholesterol in HepG2 cell line.

Objective To estimate the effect of itermittent subglottic secretions drainage(ISSD)on management of artificial airway to prevent tube-related pulmonary pneumonia.Methods One hundred ICU patients with intubation for artificial airway were divided equally into control and experiment group by random digits table.Both were managed with construction of artificial airway and besides the experiment group received ISSD. The two groups were compared in terms of incidence and occurrence time of catheter-related pneumonia, time for airway opening and ICU stay.Result The incidence and the occurrence time of pneumonia, time for airway opening and ICU stay time in the experiment group were significantly lower or shorter than those in the control group with statistical difference(all P<0.05).Conclusion ISSD is effective in decreasing the incidence of catheter related pneumonia, shortening the occurrence time of catheter related pneumonia and ICU stay time for the patients with artificial airway.

Objective To establish a multi-drug resistant model of temporal lobe epilepsy,and to observe the changes of γ-aminobutyric acid (GABA) receptor expression in the hippocampal tissues so as to explore its effects in pharmacoresistant epileptogenesis.Methods One hundred rats were selected to prepare the amygdaloid kindled model of epilepsy by chronic stimulation of amygaloid basal lateral nucleus.After the kindled model of epilepsy was prepared successfully(n =52),pharmacoresistant epileptic rats were selected according to their response to the phenobabital and phenytoin.The selected pharmacoresistant epileptic rats (n =8)were sacrificed and the hippocampus was removed to determine the GABA receptor expression,and the same number of pharmacosensitive epileptic rats was used as control.Results The pharmacoresistant epileptic rats displayed degenerative and necrotic hippocampal neurons.The arrangement of hippocampal neurons was disordered,and the structural characteristics of the arrangement of the hippocampal neurons disappeared.The gray values of GABAA-positive neurons in the hippocampal tissues (141.15 ± 14.72) increased significantly compared with the pharmacosensitive epileptic rats (92.56 ± 5.17; t =3.380,P =0.006).Western blot method demonstrated that the band of GABAA became narrowed and thin.The relative quantity of GABAA in the hippocampal tissues (0.38 ± 0.08) decreased significantly as compared with the pharmacosensitive epileptic rats (0.88 ± 0.18).A significant difference was observed (t =5.420,P =0.002).Conclusions GABA receptor expression might be decreased in the hippocampal tissues of pharmacoresistant epileptic rats.It might play a certain role in the formation of pharnmacoresistant epilepsy.

[Objective]To investigate the significance of the high-risk human papilloma virus (HPV)detection in the screening and diagnosis of cervical lesions.[Methods] The high-risk HPV DNA test results of 797 patients with cervical lesions who all accepted cytology and histopathology test were collected and analyzed retrospectively.[Results]The high-risk HPV DNA positive rates in cervicitis,cervical intraepithelial neoplasia(CIN)Ⅰ,CIN Ⅱ,CIN Ⅲ and cervical cancer were 53.41％(188/352),70.91％(117/165),87.63％(85/97),97.90％(140/143),97.50％(39/40),respectively.The sensitivity and negative predictive value of the high-risk HPV DNA detection for CIN Ⅱ and more serious lesions were 96.66％(318/329),93.29％(153/164),respectively.The detection rate of CIN Ⅱ and more serious lesions in patients with atypical squamous cells of undetermined significance(ASCUS)and positive high-risk HPV DNA was 30.03％(94/313),while the rate in patients with negative high-risk HPV DNA was 1.55％(2/129).[Conclusions] The more serious the cervical lesion is,the higher high-risk HPV DNA positive rate is.It is most closely related with CIN 11 and cervical cancer.The high-risk HPV DNA detection has high sensitivity and negative predictive value for CIN Ⅱ and more serious lesions.The high-risk HPV DNA detection has high negative predictive value in CIN Ⅱ and more serious lesions in ASCUS.

Objective To investigate the development and the risk factor of hip dislocation about children with cerebral palsy. Methods 90 children with cerebral palsy were divided with Chinese version of Gross Motor Function Classification System （GMFCS） and type of cerebral palsy. Their femoral head migration percentage was measured. Results The quadriplegia children were in the biggest risk of hip dislocation, hemiplegia children were the minimum; GMFCS Ⅰ children were in the lowest risk of hip dislocation, GMFCS Ⅴ children were the highest. Conclusion The abnormal development of the hip is correlative with the type of cerebral palsy and motor function in spastic cerebral palsy children.

[Objective]To study the association between the polymorphisms in the promoter region of Osteopontin(OPN)with hepatitis B virus(HBV)-related HCC.[Methods]A total of 225 cases diagnosed with hepatitis B virus(HBV)-related HCC and 200 age-matched patients with HBV infection without HCC were collected. Three polymorphisms(-156delG/G,-443T/C and-616T/G)in the Osteopontin promoter were genotyped using direct sequencing.[Results]The frequency of-156delG/delG genotype in the HCC group was higher than that of in the control group (P = 0.003). There was a significantly increased frequency of the allele-156delG(P<0.001)in HCC patients. Logistic regression analysis was performed to show an increase HCC risk associated with the delG variant genotype(OR1.64;95%CI 1.25~2.16). There were no differences between the groups in the genotype distributions and allele frequencies of SNP-443T/C and-616T/G.[Conclusion]Our findings suggest that allele-156delG in the Osteopontin promoter may be a marker for risk of HCC with HBV infection in Chinese Han population.

Objective To explore the relationship between the levels of leptin and leptin receptor in placental and intrauterine growth retardation.Methods Eighty seven newborns were studied .Auxological data(birth weight, length and biceps, triceps, subscapular and iliac skinfold thickness) were obtained and recorded.According to birth weight ,the subjects were divided into :the small for gestational age(SGA)group and the appropriate for gestational age (AGA) group.The levels of leptin and leptin receptor mRNA in 87 placental tissue were assayed by reverse transcription-polymerase chain reaction(RT-PCR).Results 1. The level of leptin receptor mRNA in placental was 0.894?0.291, which was positively related to the birth weight and body fat content (r=0.651,0.581,both P

Objective To determine the prevalence of female urinary incontinence among Chinese people in different areas. Methods A sampling survey of urinary incontinence was conducted on 668 female adults in a Beijing community,the Uygur region and a residential district inside the First Hospital of Peking University with questionnaire. Results The prevalence of female urinary incontinence was 46.5%(94/202) in the Beijing community,43.8%(134/306) in the Uygur Region and 40.6%(58/143) in the residential district inside the First Hospital of Peking University.The ratios of those who consulted with doctors to the separate surveyed population were 24.5%(23/94),29.1%(39/134),13.8%(8/58),respectively. Conclusions The prevalence of female urinary incontinence is similar in different population.Only a few of these women went to doctors,especially among the hospital staff and workers.
