Radiation-induced skin injury refers to the acute and chronic skin damage caused when skin is exposed to radiation. Radiation-induced skin damage may be created by nuclear disaster, radiation accident, radiation therapy, occupational exposure and so on. Approximately 95% of patients receiving radiotherapy will eventually develop into radiation-induced dermatitis during or after the treatment. As a consequence, how to appropriately prevent and remedy radiation-induced skin injury is of great practical significance. According to traditional Chinese medicine, radiation-induced skin injury belongs to fire, heat and toxin, blocking Qi and blood, injuring the muscle surface, affecting the distribution of Qi, blood and body fluid in the body, and damaging the function of viscera. This paper summarizes the cognition and development of traditional Chinese medicine theory of radiation-induced skin injury, as well as the research progress of internal and external treatment of traditional Chinese medicine, so as to provide a basis for the research and treatment of radiation-induced skin injury with traditional Chinese medicine.

Objective To investigate the related risk factors for small artery occlusion (SAO) and its 2 subtypes. Methods The clinical and imaging data in 291 patients with first-ever stroke who met the TOAST criteria of large artery atherosclerotic stroke (LAA) or SAO were collected from the Nanjing Stroke Registry Prog-am from December 2009 to November 2010. All the patients were divided into a LAA group (n = 120) and a SAO group (n = 171). The latter was redivided into either a lacunar infarction with ischemic leukoaraiosis (ILA) subgroup (n = 84)or an isolated lacunar infarction (ILI) subgroup (n = 87). The risk factors of the LAA group and SAO group and its subgroups were compared. Multivariate logistic regression analysis was conducted and the independent risk factors were screened. Results The mean age in the SAO group was larger than that in the LAA group. The proportion of the patients with hypertension and the serum homocysteine (Hcy) level were significantly higher than those in the LAA group (all P <0. 05). Multivariate logistic analysis showed that the advanced age (odds ratio, [OR] = 1.041,95% confidence interval [CI] 1.02-1.06, P = 0.045), hypertension (OR = 2. 912,95% CI 1. 11-6. 46, P =0. 031) and increased plasma Hcy (OR = 1. 109, 95% CI 1. 11-1. 32, P =0. 001) were the independent risk factors for SAO. The advanced age (OR = 1. 047,95% CI 1.00-1.09, P = 0.043), hypertension (OR = 2. 632, 95% CI 1.08-6.41, P= 0.033) and increased plasma Hcy (OR = 1. 211, 95% CI 1. 11-1. 32, P <0. 001) were the independent risk factors for ILA, while the hypercholesterolemia (OR =0. 136, 95% CI 0. 05-0. 37, P <0. 001) was the independent risk factor for ILI. Conclusions The advanced age, hypertension and increased plasma Hcy level may play important roles in the pathogenesis of SAO. The hypercholesterolemia is an independent risk factor for ILI, while advanced age, hypertension and increased plasma Hcy level are the independent risk factors for ILA.

OBJECTIVETo observe the effect of cold or hot properties of traditional Chinese medicines (TCM) on biological effect indexes, and analyze the contribution of variables on cold or hot properties, in order to preliminarily establish the discrimination mode for the biological effects of cold or hot properties.
METHODRats were randomly divided into the blank control group, cold TCM groups (Coptidis Rhizoma, Scutellariae Radix, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix and Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex and Evodiae Fructus), and orally administered with 10 mL x kg(-1) of corresponding TCM water decoctions for 30 d, twice a day. Altogether 53 biological effect indexes correlated to cold or hot properties of traditional Chinese medicines were founded by searching literatures. The data warehouse were established by using data-mining software Clementine12.0. Data of the blank control group, cold TCM groups (Coptidis Rhizoma, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix, Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex) were selected into a training set. C5.0 algorithm and C&R classification and regression algorithm were adopted to define the importance of variable, create the decision trees, and test hot or cold properties of Evodiae Fructus and Scutellariae Radix.
RESULTAccording to C&R classification and regression algorithm, SDH activity of livers was the most important hot or cold property, with the significance closed to 30%. It was followed by triglyceride, liver Na' -K' -ATPase enzyme, muscle glycogen and platelet distribution width, with the accuracy up to 97.39% in models. C5.0 algorithm showed that liver SDH activity was the most important hot or cold property, with the significance closed to 40%. It was followed by triglyceride, GOT, muscle glycogen and liver Na(+)-K(+)-ATPase enzyme, with the accuracy up to 98.26% in models. The possibilities that Evodiae Fructus is in hot property and Scutellariae Radix is in cold property were 100. 00% and 77.78% by using both C&R classification and regression algorithm and C5.0 algorithm.
CONCLUSIONThe SDH activity of liver is the most important biological effect index to distinguish cold and hot properties of TCMs. The discrimination pathway or mode of cold and hot properties is closely related to energy metabolism.

Objective To compare the changes of physiological parameters after cardiac arrest caused by asphyxia with that of cardiac arrest induced by ventricular fibrillation in rats and assess the values of the parameters on predicting ROSC and 24 h survival rate. Method Two groups of Sprague-Dwaley rats, which randomly (ramdom number) included 30 animals in each group, were investigated. Cardiac arrest were induced by asphyxia (AS group) or ventricular fibrillation(VF group). PETCO2, aortic pressure, left ventricular pressure and ECG of limb lead Ⅱ were recorded continuously, dP/dt4o was calculated with the windaq software. The parameters were compared between the two groups at baseline, precordial compression(PC) 10 s, PC 1 min, PC 3 min, ROSC 1 h and ROSC 2 h. The relations were explored between the parameters and ROSC/24 h survival rate. Results PETCO2,aortic pressure, left ventricular pressure and ECG have distinctive changes in the two groups. In group VF, PETCO2 of ROSC rats at BL, PC 1 min and PC 3 min were higher than those of Non-ROSC rats (P < 0.05); PETCO2of 24 h survival rats at ROSC 1 h and ROSC 2 h were higher than those of 24 h death rats (P < 0.05), which were not observed in the group AS. dP/dt40 and - dP/dt40 at ROSC 1 h and ROSC 2 h in group VF were higher than those in group AS (P < 0.05). Conclusions Physiological parameters after cardiac arrest caused by asphyxia or that of cardiac arrest induced by ventricular fibrillation in rats have unique features respectively. PETCO2 in cardiac arrest caused by ventricular fibrillation may predict ROSC and 24 h survival rate. Researchers have to select the appropriate cardiac arrest model according their research purposes and clinical requirments.
