AIM: To investigate the anti - tumor effect of Weimaining (WMN) on a murine Lewis lung carcinoma (3LL) and the influence on the cell cycle. METHODS: The inhibitory rate of WMN in 3LL growth was detected by replicating the model of 3LL. The effect of the drug on 3LL cell cycle and the influence of the drug on the expression of cy clin D1 protein were investigated by flow cytometry and immunohistochemical staining. RESULTS: The results showed that the inhibitory rate of drug in 3LL is 19. 14%, 33.59%, 40. 63% and 51.56% respectively at dosage ranging from 100,cells in G0 -G1 phase and decreases the expression of cyclin D1 protein. CONCLUSION: WMN inhibits the growth of 3LL cells in vivo by decreasing the expression of cyclin D1, blocking the cells in G0 - G1 phase and preventing the cells transition from G1 to S phase while DNA is replicated.

METHODS: The anti-metastasis effect of weimaining in vivo was detected in the grafting lung metastasis model of murine Lewis lung carcinoma. The effects of the drug on the expression of CD34 and E-cadherin were investigated by immunohistochemical staining and RT-PCR. RESULTS: Weimaining effectively inhibited the lung metastasis of 3LL at a concentration of 250 mg?kg -1?d -1, significantly suppressed the expression of CD34 and increased the expression levels of E-cadherin protein and mRNA in 3LL cells. CONCLUSIONS: Weimaining inhibits the metastasis of murine Lewis lung carcinoma (3LL) in vivo via increasing the expression of E-cadherin and decreasing microvessel density of tumor tissue.
4.Isolation and structure identification of grape seed polyphenols and its effects on oxidative damage to cellular DNA.
Acta Pharmaceutica Sinica 2004;39(11):869-875
AIMTo isolate polyphenols from grape seeds and to evaluate their antioxidant effects.
METHODSPure compounds were isolated by using Diaion HP20, Toyopearl HW40 chromatography repeatedly, as well as semi-preparative RP-HPLC, from ethyl acetate extract of grape seeds. IR, MS, NMR, CD, X-Ray crystal diffraction spectral analysis were used to identify the structures. The antioxidant effects of different type of structures were screened by reducing power and DPPH (alpha,alpha-diphenyl-beta-picrylhydrazyl) free radical scavenging tests. Then, SCGE (single cell gel-electrophoresis) technique was used to investigate the effects of these potent antioxidant phytochemicals on cellular DNA oxidative damage with mice spleen cells, damage was induced by H2O2.
RESULTSEleven compounds were obtained including 3 novel structures, viniferones A, B and C. Proanthocyanidin B4, catecin, epicatechin and gallic acid showed strong antioxidant power, and at lower concentration (10 micromol x L(-1), 25 micromol x L(-1)), they can prevent cellular DNA damage, while 150 micromol x L(-1) catechin induced damage by itself.
CONCLUSIONViniferones A, B and C were reported for the first time. That polyphenols investigated were shown to be good cellular DNA oxidative damage-preventing phytochemicals at lower concentration, could be used to explain the nutrient effect of grape seed polyphenols at certain degree. At the same time, higher concentration of polyphenols can induce oxidative damage, suggesting that dose is one factor to determine the nutrient effects.

OBJECTIVETo explore the diagnostic value of the radiologic characteristics of osteoporotic Kummell's disease.
METHODSTotal 16 patients with pathologically confirmed osteoporotic Kummell's diseases were reviewed from May 2010 to May 2012, including 4 males and 12 females with the mean age of 73.4 years (ranged, 67 to 83 years old). Radiologic imagings of all patients, including X-ray, CT and MRI, were analyzed retrospectively.
RESULTSIntravertebral linear clefts could be seen on the AP and lateral X-ray films of vertebrae. Sagittal and axial CT scans demonstrated the vacuum cleft phenomenon with liquid and air was identified within the vertebral body. Sagittal MRI showed the callapsed vertebral segment and the area of fluid signal with clear and intact border within the vertebral body. The fluid signal was low on T1-weighted images and high on T2-weighted images and stir images, which was corresponding to an intravertebral vacuum cleft.
CONCLUSIONThe radiologic characteristics of Kurmmell's diseases can provide valuable evidences for the early diagnosis.

Methods Through multi-stage randomized cluster sampling,a face-to-face study with standard questionnaire was carried out among residents aged above 15 years,from June to December 2008,with descriptive nature. Results Totally,44 686 people,with 21 524 males and 23 162 females at age 15 and over were investigated,including 34 391 of them from rural areas and 10 295 from the urban population. Data regarding rates on ever smoked and current smoking,regular smoking,heavy smoking,and average numbers of cigarettes smoked per day,types of tobacco products smoked,rates on quitting smoking successfully,relapse,passive smoke exposure etc.,were 22.45%,21.40%,15.49%,9.49%,15.09/d,4.68%,5.91% and 14.12% respectively. There were no significant differences in the rates of overall smoking,current smoking and regular smoking among urban and rural residents (P>0.05). However,rates of successfully quitting smoking and passive smoke exposure in the urban areas were higher than those in the rural areas (P<0.05). Rates regarding relapse,heavy smoking and average numbers of cigarettes smoked per day in the rural areas were higher than those in the urban areas(P<0.05). Rates on smoking,current smoking,regular smoking,heavy smoking,relapse and average numbers of cigarettes smoked per day were higher in males than those in females (P<0.05). Rates of quitting smoking successfully and passive smoke exposure were higher in females than those in males (P< 0.05). The major types of tobacco products smoked by people aged 15 years old and above were cigarettes (85.17%),and Chinese pipes (3.24%). Conclusion Smoking was quite common in people from Xuzhou. Our data suggested that health education should be strengthened and sustainable intervention measures be developed and implemented to control the tobacco use in the area.

OBJECTIVETo develop a quick identification method for the sun-dried and sulfur-fumigated Angelicae Sinensis Radix used by Fourier transform infrared spectroscopy (FTIR) combined with second derivative infrared spectroscopy.
METHODThe alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Angelicae Sinensis Radix were analyzed by using FTIR, the further analysis was used by second derivative infrared spectroscopy.
RESULTThere existed differences between their infrared spectra either extracted by ethanol or water, while the distinctions were more obvious after analyzing their alcoholic and aqueous extracts through high resolution of second derivative infrared spectroscopy. Infrared spectra showed that the absorption peaks of Angelicae Sinensis Radix were significantly reduced and a new absorption peak appeared after sulfur-fumigated process in alcoholic extracts, while both of them changed markedly in the "fingerprint region" ranging from 1 000 to 400 cm(-1) in aqueous extracts. Second derivative spectra showed that the absorption peaks of sulfur-fumigated Angelicae Sinensis Radix extracted by ethanol weakened and disappeared at about 3 578 cm(-1) and 3 541 cm(-1), while both of them differed significantly from each other ranging from 1 400 to 1 200 cm(-1) as well as 800 cm(-1) to 600 cm(-1), difference also existed between them extracted by water ranging from about 3 900 to 3 850 cm(-1) and 3 800 to 3 750 cm(-1).
CONCLUSIONThe FTIS method combined with second derivative can be utilized to distinguish sun-dried and sulfur-fumigated Angelicae Sinensis Radix efficiently, conveniently and accurately, and provide a basis for identification and quality control of Angelicae Sinensis Radix.
