增色方联合毫火针治疗对白癜风患者抗氧化应激反应及生活质量的影响

目的:探讨增色方联合毫火针治疗对白癜风患者抗氧化应激反应及生活质量的影响。方法:选取本院2023年6月~2024年5月收治的100例白癜风患者,随机分为2组,西医组50例采用0.1%他克莫司软膏治疗,中西医组50例采用0.1%他克莫司软膏 + 增色方联合毫火针治疗。对比2组患者的中医证候积分、皮损面积、抗氧化应激反应[超氧化物歧化酶(SOD)、丙二醛(MDA)]、生活质量[皮肤病生活质量指数(DLQI)]、总体疗效。结果:2组治疗后中医证候积分的各项评分均较本组治疗前降低,中西医组低于西医组,P Objective: To explore the effects of Zengse Fang combined with Haohuo Needle therapy on antioxidant stress response and quality of life in vitiligo patients. Method: 100 vitiligo patients admitted to our hospital from June 2023 to May 2024 were randomly divided into two groups. The Western medicine group (50 cases) was treated with 0.1% tacrolimus ointment, while the Chinese and Western medicine group (50 cases) was treated with 0.1% tacrolimus ointment + color enhancing formula combined with filiform needle. Compare the traditional Chinese medicine syndrome score, skin lesion area, antioxidant stress response (superoxide dismutase (SOD), malondialdehyde (MDA)), quality of life (Dermatological Quality of Life Index (DLQI)), and overall efficacy between two groups of patients. Result: After treatment, the scores of traditional Chinese medicine syndrome scores in both groups decreased compared to before treatment, with the Chinese and Western medicine group being lower than the Western medicine group, P < 0.05. The area of skin lesions in both groups decreased compared to before treatment, and the Chinese and Western medicine group was smaller than the Western medicine group, P < 0.05. The SOD in both groups increased compared to before treatment, and MDA decreased compared to before treatment. The SOD in the Chinese and Western medicine group was higher than that in the Western medicine group, and MDA was lower than that in the Western medicine group, P < 0.05. The DLQI scores in both groups decreased compared to before treatment, with the Chinese and Western medicine group being lower than that in the Western medicine group, P < 0.05. The total effective rate in the Chinese and Western medicine group was higher than that in the Western medicine group, P < 0.05. Conclusion: The combination of Zengse Fang and Haohuo Needle has a good effect on treating vitiligo, which can alleviate patient symptoms, reduce skin lesion area, improve antioxidant stress response indicators, and improve quality of life. It is worth using.

增色方联合毫火针治疗对白癜风患者血清中IFN-γ及CXCL-10影响的研究

目的探讨干扰素-γ(IFN-γ)、CXC趋化因子配体10(CXCL10)在气滞血瘀型白癜风患者外周血中的表达及增色方联合火针治疗白癜风的临床疗效。方法选取2019年5月至2021年8月在黄石市中心医院皮肤科就诊的120例证气滞血瘀型白癜风患者作为研究对象。按数字表法随机分为增色方治疗组(n=40)、毫火针治疗组(n=40)和联合治疗组(n=40)。增色方治疗组单纯口服中药增色方治疗,毫火针治疗组单纯外用毫火针治疗。联合治疗组在口服增色方的基础上外用毫火针治疗。疗程三个月,观察三组患者临床疗效,检测三组患者外周血IFN-γ、CXCL10表达水平并进行分析比较,并随访患者复发率情况。结果联合治疗组治疗后外周血IFN-γ、CXCL10水平均低于增色方治疗组和毫火针治疗组治疗后IFN-γ、CXCL10水平,差异具有统计学意义(P<0.05);且联合治疗组复发率同增色方治疗组和毫火针治疗组相比明显降低,差异具有统计学意义(P<0.05)。结论在口服增色方的基础上外用毫火针治疗气滞血瘀型白癜风患者,疗效确切且复发率低,其作用机制可能是通过调控IFN-γ、CXCL10的表达发挥调节机体免疫平衡,减少白癜风患者表皮和体内的炎症反应。

Dark Color ZnO Quasi-One-Dimensional Nanostructures Grown by Hydrothermal Method and Modulation of their Optical Properties

Zinc oxide has a large energy gap and thus it has potential application in the field of solar cells by tuning the absorption of sunlight. In order to enhance its absorption of sunlight,dark color zinc oxides have been prepared by traditional hydrothermal method directly using a zinc foil as both source and substrate. We found that we could tune the optical properties of ZnO samples by changing the temperature. In particular, increasing temperature could significantly reduce the reflectivity of solar energy in the visible range. We speculate that the phenomenon is relevant to the sharp cone morphology of the ZnO nanorods grown on the surface of Zn foils, which furthermore enhance refraction and reflection of light in the nanorods. The capacity to improve the light absorption of ZnO may have a bright application in raising the efficiency of solar cells.

Black or Green?Economic Growth Patterns in China under Low Carbon Economy Targets

Achieving dual goals of economic growth and carbon emission reduction is a major issue in China. In this paper we deifne three economic growth patterns （green growth, brown growth and black growth） according to the relationship between economic scale and carbon emissions, and then trace the historical trajectory of economic growth over the last 40 years. Granger causality is used to test China’s economic growth and carbon emission linkage. We argue that green growth means that the rate of carbon emission reduction is faster than the increase in GDP. When carbon intensity reduction is slower than GDP growth, brown growth occurs. Black growth occurs when both carbon intensity and economic scale increase. For China, we denote the four periods of black growth （1971–1977）, brown growth （1978–2001）, black growth （2002–2004）, and brown growth （2004–2010）. Granger causality tests indicate that mutual causality between carbon emissions and economic growth exists in the short term, but not the long term. In order to achieve the goals of economic growth and carbon intensity reduction, it is necessary for China to actively participate in global carbon reduction activities, technological innovation and ecological civilization construction.

Improved single image dehazing using dark channel prior

An improved single image dehazing method based on dark channel prior and wavelet transform is proposed. This proposed method employs wavelet transform and guided filter instead of the soft matting procedure to estimate and refine the depth map of haze images. Moreover, a contrast enhancement method based on just noticeable difference(JND) and quadratic function is adopted to enhance the contrast for the dehazed image, since the scene radiance is usually not as bright as the atmospheric light,and the dehazed image looks dim. The experimental results show that the proposed approach can effectively enhance the haze image and is well suitable for implementing on the surveillance and obstacle detection systems.
