Objective To investigate the potential effect of 4-amino-pynidine(4-AP)on human cervical carcinoma cell line HeLa to 252Cf neutron ray.Methods HeLa cells were treated with 4-AP(0,1,5,10,20 mmol/L,respectively)and then exposed to 0.67 Gy 252Cf neutron ray.The effect of 4-AP on proliferation of HeLa cells was assessed by MTT assay.Cell apoptosis were detected by flow cytometry.Reverse transcription polymerase chain reaction(RT-PCR)and Western blotting were used to investigate the levels of HIF-1? mRNA and protein of HeLa cells treated with 4-AP(0,20 mmol/L)and 0.67 Gy 252Cf neutron ray.Results After HeLa cells treated with 0,1,5,10,20 mmol/L 4-AP were exposed to 0.67 Gy 252Cf neutron ray for 48 h,their inhibitory rate was 0,(38.81 ?3.45)%,(46.63?3.88)%,(63.58?6.19)%,(77.51?8.87)%,and their apoptotic rate was(3.15?0.85)%,(8.01?1.19)%,(16.00?1.58)%,(47.20?3.18)%,(62.56?4.27)%,respectively,suggesting 4-AP may inhibit the proliferation of HeLa cells and induce their apoptosis in a dose-dependent manner(P0.05).However,after treated with 20 mmol/L 4-AP and exposed to 0.67 Gy 252Cf neutron ray for 24,48 and 72 h,the optical density ratio of HIF-1? mRNA/?-actin of HeLa cells was(0.401?0.121),(0.364?0.142),(0.257?0.137),(0.165?0.099),while the optical density ratio of HIF-1? protain/?-actin were(0.879?0.117),(0.645?0.115),(0.312?0.114),(0.130?0.118),showing that the levels of HIF-1? mRNA and protein both declined(P

Objective: To observe the therapeutic efficacy of tuina plus cupping on chronic fatigue syndrome (CFS). Methods: A total of 100 CFS patients meeting the inclusion criteria were randomly divided into a treatment group and a control group according to the random number table in the sequence of visit, with 50 patients in each group. The treatment group was treated with tuina plus cupping therapy, 3 times a week. The control group was given oral tablets of wild American ginseng lozenges. After 3 months of treatment, the score of fatigue questionnaire scale (FS-14) was observed and the efficacy was evaluated. Results: The total effective rate was 92.0％ in the treatment group, versus 76.0％ in the control group and the difference between the two groups was statistically significant (P<0.05). After treatment, the FS-14 scores of the two groups decreased, and the intra-group differences were statistically significant (both P<0.05). The change of FS-14 score after treatment in the treatment group was more significant than that in the control group (P<0.05). Conclusion: Tuina plus cupping is effective for CFS, and can improve fatigue symptoms significantly.

BACKGROUND: Bronchial asthma is one of those diseases that are significantly affected by meteorological factors. There is close relationship between asthma attack and meteorological factor. There have been some studies on the relationship between asthma and meteorological factors at home and abroad, but the results are various due to different area conditions.OBJECTIVE: To analyze the relationship between asthmatic attack and meteorological factors in children in Qingdao city.DESIGN: Observational experiment.SETTING: The Affiliated Hospital of Qingdao University Medical College.PARTICIPANTS: Altogether 445 inpatient children, 307 males, 138 females, aged ＜ 14 years, who were diagnosed of asthma attack definitely, of the Affiliated Hospital of Qingdao University Medical University, Qingdao Haici Hospital,Qingdao Children Hospital between January 1st 2000 and December 31st 2004 were retrieved.METHODS: The asthmatic attack time of 445 children patients with asthmatic attack of Qingdao city and concurrent month mean temperature, air pressure, relative humidity, wind speed and other meteorologic al data were collected.Seasonal rhythm of asthmatic attack in children and the relationship between asthmatic attack and meteorological factors were analyzed with circular distribution analysis and linear regression analysis, respectively.MAIN OUTCOME MEASURES: ①Month attack information of 445 asthma patients. ② Circular distribution analysis results of asthmatic attack time. ③ Linear regression analysis results about the relationship between asthma attack and meteorological factors.RESULTS: ① Data revealed that asthmatic attack in Qingdao city focused on November, December, January and February, which took up 47.9% of total amount in that year. There were 307 male patients (incidence 3.12%)in a year,female patients only 138 cases (incidence 1.51%), which revealed that boys have a higher incidence of asthma attack than girls. ②The peak season of incidence of asthmatic attack was found in winter and peak season for male and female patients was in January and December, respectively (P ＜ 0.05). ③ Higher incidence of asthmatic attack of children was related with higher air pressure, lower temperature, lower relative humidity(r =0.435, -0.320, -0.296, all P ＜ 0.05).CONCLUSION: The incidence of asthma attack presents seasonal rhythm in Qingdao city and it is influenced by climate conditions. Therefore, enough consideration of meteorological factors should be paid on preventive works for asthma.

Background Nearly over 40 years have elapsed since the original findings of visual cortical plasticity,but none of drug has been found for curing amblyopia effectively. Objective The goal of this study was to investigate the effects of different dose of levodopa on flash visual evoked potential(F-VEP)and morphology of visual cortex cells in monocular deprivation rat and explore the possible mechanism of curing amblyopia.Methods Monocular deprivation model were established by suturing eyelids of 30 2-week-old Sprague Dawley(SD)rats for 4 weeks.The 30 SD rats were then divided into 3 groups randomly and 10 rats for each group.Normal saline.20 ms/kg levodopa,80 ms/kg levodopa were intragastrically administered once per day after modeling respectively for 4 weeks.F-VEP was recorded after establishment of model and administration of drug respectively.The rats were sacrificed and the visual cogex was obtained for histological examination,and TUNEL technique was used to assess the structural change of visual cortex.Results The latency of P1 wave was significantly longer in the deprived eye than the normal eyes(P<0.05).After administration of levodopa,the latent periods of Pl wave in the deprived eye were obviously shortened in comparison with before administration of levodopa in 20 ms/kg and 80 mg/kg levodopa group (P<0.05).The difference values of latent period of P1 wave between before and after administration of drug showed statistically significant change in three groups(P<0.05).No evidently alterations were found in the amplitude differences of N1 P1 and P1 N2 waves among three groups(P>0.05).The number and structure of neurons in contralateral visual cortex of non-deprived eye were normal.However,the numbers of neurons in deprived eye were significantly less and presented the signs of para-apoptosis in normal saline group.In 20 mg/kg levodopa groups,the alterations of number and morphology in neurons of rat visual eogex were slight.TUNEL assay revealed that the numbers of positive neurons in contralateral visual codex of non-deprived eye were 2.20±1.23.while those in deprived eye were 53.7±9.36,27.20 4±5.96 and 10.70±3.23 in normal saline group,20 mg/kg and 80 mg/kg levodopa group respectively,showing a significant difference among them(P>0.05).After usage of levodopa,the numbers of positive neurons was negatively correlated with the difference value of P,latent period of VEP(r=-0.815,P=0.000).Conclusion Levodopa has a therapeutic effect on rat deprived eye,and its possible mechanism is inhibiting the para-apoptosis of neurons and participating in the development and plasticity of visual system.
