E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.

Objective: To observe the clinical effect of Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method versus ordinary acupuncture on superficial fascia for treating neck type cervical spondylopathy in Kyrgyz. Methods:A total of 64 Kyrgyz patients conforming to the diagnostic criteria of neck type cervical spondylopathy were included. The patients were randomized into a Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and a conventional acupuncture group, with 32 cases in each group. Patients in the Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were treated with Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method to stimulate the superficial fascia, the stimulation sites were primarily located at bilateral sides of the cervical vertebra as well as the trigger points in shoulder-neck region; patients in the conventional acupuncture group were punctured at the same acupoints, with twirling reducing method, and the depth of insertion was determined by the treated region. Patients in both groups received treatment every day for a succession of 5 d as a course, with a 2-day interval between 2 courses, and the whole treatment lasted for 3 courses. After 3 courses of treatment, the McGill pain questionnaire (MPQ) and neck disability index (NDI) were measured to compare the clinical effect between the two groups. Results: After treatment, scores of MPQ and NDI scale dropped when compared with those before treatment, and the differences showed statistical significance (allP<0.05); scores of MPQ and NDI in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were substantially lower than those in the conventional acupuncture group, and the differences showed statistical significance (allP<0.05). The total effective rate was 96.9％ in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and the cured rate was 78.1％, which were higher than 81.3％ and 40.6％ in the conventional acupuncture group, and the differences showed statistical significance (bothP<0.05). Conclusion: Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method by stimulating superficial fascia to treat cervical spondylopathy in Kyrgyz can produce a better clinical effect than conventional acupuncture treatment, and is effective in improving pain and stiffness in patients, and thus is worth clinical popularization.

Objective To evaluate the nutritional status of iodine of pregnant and lactating women in coastal and inland areas of Zhejiang province,and to provide scientific basis for iodine supplementation.Methods In 2009,five coastal cities,five coastal counties and three inland areas from Zhejiang province were selected by the cluster sampling method,and one sub-district(township) was randomly selected in each city (county),then one community (village) was randomly selected in each sub-district (township).Thirty pregnant women,thirty lactating women and fifty children aged 8 - 10,were randomly selected in each community(village) as the investigation objects to collect instant urine samples to detect urine iodine,and to collect thirty resident edible salt and some water samples to detect salt iodine and water iodine,if the numbers of water source were more than 5 then 1 water sample was collected by their location of east,south,west,north and center in each community(village),otherwise,the numbers of water samples collected were equal to the number of community (village).Results The medians of salt iodine of coastal city,coastal county and inland area were 28.42,25.29,and 33.24 mg/kg,respectively,and the medians of water iodine correspondingly were 5.41,11.52,and 2.80 μg/L,respectively.The medians of urinary iodine of pregnant and lactating women in Zhejiang province were 148.72 and 161.34 μg/L,respectively,which were less than that of children aged 8 - 10(231.02 μg/L,Z =8.57,8.24,all P ＜ 0.017).The medians of urinary iodine in pregnant women from different areas were ranked in order as inland areas(211.42 μg/L),coastal counties (150.51 μg/L) and coastal cities (123.33 μg/L,Z =2.80,5.31,2.42,all P ＜ 0.017),and in lactating women,the medians of urinary iodine in inland areas( 197.43 μg/L) was higher than that in coastal cities( 139.64 μg/L,Z =4.03,P ＜ 0.017).Conclusions The overall levels of iodine nutrition in lactating and pregnant women in Zhejiang province are in the appropriate level,but that of the pregnant women in the coastal cities is inadequate.

The endophytic microorganisms found widely in many kinds of plants mediate various effects to theirs hosts. In this study, seven different dominant endophytes (SDE01 to 07) isolated from a Hy-peraccumulator-Solanum nigrum L. were resistant to Cd2+, and the strain SDE06 survived even in the medium containing 80 mg/L of Cd2+. Bacteria strain SDE06 was identified as Bacillus sp.. The removal of Cd2+ of SDE06 in different conditions were studied. Under the optimal conditions, the incubating time was 36 h, the solution pH 6.0, the temperature was 37?C and the Cd2+ concentration of medium was 20 mg/L, the highest removal rate was up to 80.2% at this condition.

Objective To explore a more reasonable and effective therapeutic regimen and evaluate prognostic factors in hepatoblastoma patients after combined therapy.Methods Sixteen patients diagnosed on hepatoblastoma between Jan.2000 and Nov.2007 were reviewed and followed-up.Resection with chemotherapy was taken among 16 cases.Chemotherapy included pre-operation and post-operation.Five cases were cured by transcatheter arterial chemombolization(TACE).Six cases were cured by single chemotherapy(both TACE and single chemotherapy were taken in 2 cases).Five cases weren't cured by pre-operation chemotherapy.Nine cases were subjected to curative resection,3 cases to alleviative resection,2 cases with single chemotherapy,1 case with single TACE,and 1 case refused operation and left hospital.Their mean survival duration was 13.5 months(3-98 months).SPSS 13.0 software was used to analyze the data.Results The total survival rate of cases as stage Ⅳ as lower than cases as stage Ⅰ,Ⅱand Ⅲ.Both alpha-fetoprotein(AFP)100 000 ?g/L cases had worse survival rate.The prognosis of mixed type was better than fetal type,embryonal type and anaplasia type.The survival rate of cases with standard chemotherapy was higher than cases with unstandard chemotherapy.And the surgical resection cases had better survival chance than non-surgical resection cases.The survival rate of surgical residual cases was worse than non-surgical residual cases.Conclusions Chemotherapy can improve the total survival rate and long-term survival rate of hepatoblastoma patients.TACE is a safe and effective choice for hepatoblastoma patients.We need to be alert and make the diagnosis as early as possibe,and treat it early and properly.

Objective To investigate the significance and effect of ultrasonic diagnosis on the autologous bone marrow mesenchymal stem cells (MSC) in angiogenesis. Methods Twenty-four New Zealand rabbits were divided into experiment group (12) and the control group (12). Then rabbit bone marrow MSCs from experiment group were isolated, caltured and marked with Brdu. After ischemic hind limb animal model on all rabbits was set up, autologous bone marrow MSCs were directly injected into the ischemic hind limb muscles in experiment group while same volume normal saline was used in the control group. Two weeks after the implantation of autologous bone marrow MSCs, 2D and color Doppler flow imaging (CDFI) detection were used in rabbit femoral artery of the two groups to observe the inner diameter of the blood vessel, the peak velocity and the acceleration time. The disposition of transplaned cells and the state of angiogenesis in ischemic muscles were assessed using immunofluorescence staining. Results The results of 2D and Doppler ultrasound detection showed the inner diameter of the blood vessel and the peak velocity of the blood current in experiment group obviously higher than that of the control group , and the acceleration time was obviously smaller than that of the control group P<0.01. The immunofluorescence staining showed there were transplanted cells existed in transplanted portion and state of angiogenesis was supurior obviously than that of the control. Conclusions Bone marrow MSCs had the effect to promote angiogenesis. Implantation of autologous bone marrow MSCs was a simple and efficient therapeutic method for the ischemia hind limb. Using high-frequency ultrasound to detect femoral artery may provide a practical and useful method to evaluate the effect on implanted autologous bone marrow mesenchymal stem cells.

The present study aimed to investigate the effect of Glomus versiforme and Trichodema harzianum on the growth and quality of Salvia miltiorrhiza continuous cropping under field conditions. The field plot experiment was conducted, these active components in the plant were analyzed by HPLC, the root diseases incidence rate of S. miltiorrhiza determined by observation and counting, and relative parameters were measured. The data was statistically processed. The result showed that inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum significantly decreased the root diseases incidence rate of S. miltiorrhiza, and combined inoculation of G. versiforme with T. harzianum was better than other treatments. All treatments improved accumulation of active ingredients in root. Inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum significantly increased the content of salvianolic acid B and cryptotanshinone of root (P < 0.05), Inoculation of G. versiforme, T. harzianum and combined inoculation of G. versiforme with T. harzianum significantly enhanced the content of tanshinone I and tanshinone II(A) of the root (P < 0.05). It may conclude that inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum can effectively reduce the root diseases incidence of continuous cropping S. miltiorrhiza, and improve the quality of S. miltiorrhiza.
