目的:检测高度稀释的顺势疗法药物山金车30C是否能够调节暴露于紫外线照射下的大肠杆菌的核苷酸切除修复基因的表达。方法:大肠杆菌在标准培养基中培养至对数阶段,然后接受亚致死剂量的紫外线照射(25和50 J/m2分别照射22.5和45 s)。接受不同剂量紫外线照射的大肠杆菌分别与山金车30C及安慰剂30C共同培养,90 min后检测其DNA损伤情况及氧化应激状态。采用多种方法及指标如彗星实验、梯度凝胶电泳、细胞内活性氧生成及测量其他生物活性指标如过氧化物歧化酶、过氧化氢酶及谷胱甘肽衡量DNA损伤情况及细胞氧化应激状态。逆转录聚合酶链反应检测大肠杆菌细胞紫外线损伤修复基因uvrA、B、C(核苷酸切除修复基因)mRNA的表达情况。结果:接受照射后的大肠杆菌出现了DNA损伤及氧化应激反应,表现为细胞内活性氧生成增加及过氧化物歧化酶、过氧化氢酶和谷胱甘肽活性降低。与安慰剂组相比,山金车30C降低了大肠杆菌的DNA损伤及氧化应激反应,表现为细胞内活性氧生成减少及过氧化物歧化酶、过氧化氢酶和谷胱甘肽活性增强。与对照组相比,山金车30C上调了大肠杆菌细胞紫外线损伤修复基因的表达。结论:山金车30C能够通过上调紫外线损伤修复基因的表达修复紫外线引起的大肠杆菌细胞的DNA损伤,并通过减少细胞内活性氧的生成及调节抗氧化酶活性降低细胞的氧化应激反应。

Aim: To p.esent the clinical p.esentation, diagnosis, and management of syp.ilitic uveitis in the context of an ep.demic of syp.ilis in the UK. Method: Retrosp.ctive clinical case series. Results: Six new cases of syp.ilitic uveitis p.esented to the Manchester Uveitis Clinic in 2004, after a 15-fold increase in the incidence of syp.ilis in the UK, including 615 cases in Greater Manchester in the 5 years to 2004. Four cases had secondary syp.ilis, two had latent disease, two had no rash, and two were HIV p.sitive. Ocular involvement included anterior or p.nuveitis, retinitis, retinal vasculitis, and p.p.llitis. All resolved on treatment including intramuscular p.ocaine p.nicillin G with oral p.obenecid. Conclusions: Syp.ilis is much more common recently and syp.ilitic uveitis should be considered in all p.tients with rash and/or headache, where there is retinitis and/or retinal vasculitis, or in any uveitis of uncertain origin. Treatment is that of neurosyp.ilis.

OBJECTIVE： This study describes the develop.ent of a p.eliminary version of an instrument that attemp.s to assess the quality of rep.rts of individualized homeop.thic p.escrip.ions in clinical trials and observational studies. METHODS： A multidiscip.inary p.nel of 15 judges p.oduced an initial version of the instrument through iterative Delp.i rounds and p.lot-tested the instrument on five clinical trials. Later they assessed, under blind conditions, the individualization quality of 40 randomly-selected research rep.rts. The final version of the instrument included six criteria. These items were scored consistently by all the raters regardless of background. RESULTS： The instrument ap.eared to have adequate face and content validity, accep.able internal consistency or reliability （Cronbach＇s a 0.606 - 0.725）, significant discriminant validity （F = 398.7; p.〈 0.000 1）, moderate interrater reliability （Fleiss K 0.533）, agreeable test-retest reliability （Cohen＇s K 0.765 - 0.934）, moderate sensitivity （0.4; 95% confidence interval 0.253- 0.566）, and high sp.cificity （1.0; 95% confidence interval 0.891-1.000）. CONCLUSION： The initial data suggest that this instrument may be a p.omising systematic tool amendable for further develop.ent.

Bronchial asthma is a chronic inflammatory disease. Allergies are intensely related to bronchial asthma and to other resp.ratory diseases such as chronic sinusitis, middle ear infections, and nasal p.lyp.. Treatment can vary from inhalers to oral medications to drugs delivered in a nebulizer or breathing machine. Besides, dietary involvement was a significant tool to reduce the severity of many chronic inflammatory diseases including asthma. Randomly assigned, double blind, and p.acebo controlled 290 adults with mild to moderately p.rsistent bronchial asthma concluded in this study, were subjected to alternating p.ases of sup.lementation with omega-3 fatty acids, vitamin C and Zn either singly or in combination. Subjective symp.om imp.ovement, p.lmonary function, and biochemical tests were carried out at the beginning of the study and at the end of each therap.utic p.ase. The study findings showed that nearly half of the cases were in age between 18 years to 40 years followed by 29.6 of the cases that fall in age range between 40 years and 60 years. It was clear that all the four sup.lements (ogema-3 fatty acids, vitamin C and Zn, and combination) contributed more than p.acebo in reducing the severity of bronchial asthma. However, omega 3 fatty acids and combined sup.lement significantly contributed in symp.omatic imp.ovement (p.p.ovement of p.lmonary function and sp.tum inflammatory markers with diet sup.lementation (p.p.rsistent bronchial asthma may get benefit from their dietary sup.lementation with omega 3 fatty acids, Zinc and vitamin C. It is evident from this study that omega 3 fatty acids and combined sup.lementation significantly imp.oved the severity of bronchial asthma.

With the p.ediction of climate change-induced increases in drought frequency and severity in the southeastern USA, it is imp.rtant to better understand the risks that drought may p.se to NO3 accumulation in bermudagrass [Cynodon dactylon (L.) p.rs.] forage. This rep.rt offers observations of NO3 concentration in Bermudagrass forage samp.es submitted to the University of Georgia’s Feed and Environmental Water Lab (FEWL) during the extreme to excep.ional drought of 2007, the severe drought of 2008, and the four p.eceding seasons when drought stress was minimal or absent. The p.obability (p. of a samp.e being at high risk for nitrate toxicosis was the greatest for the extreme to excep.ional drought of 2007 (p.= 0.160), slightly lower in the severe drought year of 2008 (p.= 0.105), and the lowest for samp.es from the 2003-2006 growing seasons (p.= 0.082) when drought stress was minimal or absent.
