Abstract: This paper deals with the distribution of Oribotritia in Xinjiang grasslands,based on a systematical survey of the mites in 17 natural areas during the period of 1983 to 1989.By analysing and comparing the data on the count and population distribution of the mites from 987 spots,it has been found that the distribution of the mites has a regularity characterized by an unbalanced, regional, congregate, seasonal, and environment-dependent distribution.
Electrochemical Therapy of Tumors

Conference Papers in Science , 2013, DOI: 10.1155/2013/858319
Abstract: Application of electric current for the tumor destruction has a long time history. The theory of the direct galvanic current (galvanotherapy, GT) is worked out by B. Nordenstrom in the frame of biologically closed electric circuits (BCECs). Later, GT was extended by chemical considerations (EChT), and, starting with pioneering work of Professor Xin Yu Ling, a wide, intensive application had been developed in China. My objective is showing the principles and practice of the EChT treatment modality for multiple advanced lesions. 1. Introduction The efficacy of electrochemical therapy (EChT) in mice with implanted Jensen sarcoma tumors was reported in 1953 by Reis and Henninger [1]. However, the clinical application of this modality was initiated by the Swedish radiologist, Nordenstrom. In 1983, he published a book in which he described his theory of biologically closed electrical circuits (BCECs) and the results of two decades of research on EChT treatment of malignancies in animals based on this [2]. He also reported the results of EChT in 20 lung cancer patients with 26 tumors in which he used the “skinny needle” he had developed for biopsy purposes as an electrode. Followup after 2 to 5 years revealed that 12 tumors had either disappeared or were markedly reduced in size. This study stimulated interest in utilizing EChT for treating lung malignancies, and Japanese researchers subsequently confirmed Nordenstrom’s results in animals and in several patients [3–7]. Anyway, the real application of the technique widely has begun in China (China-Japan Friendship Hospital as the center of this application) after it was introduced to the country in 1987. Electrodes, which special produced by platinum, were inserted into tumor and connecting them with an apparatus, the current arouse strong chemical reactions around electrodes and led degeneration and necrosis of tumor cells. It is a new type method to treat tumor without surgical resection. The final result is caused by current inducing chemical reactions, so we call it EChT. The advantages of EChT are that it is much safer, easier to administer, less costly than surgical procedures, and can be just as effective in certain instances. In addition, it provides an opportunity to treat tumors in those patients in whom surgery, radiation, and/or chemotherapy has not been successful or may be contraindicated. 2. Experimental Studies on Mechanism of EChT It has been well established that tumor cells are more sensitive to certain changes in the environment than adjacent normal cells. Various treatment approaches,

Abstract: An electrochemical bionic sensor for cholesterol detection is developed with molecular imprinting self-assembled film deposited on the screen printed gold electrode. The surface topography of planar bare gold electrode and thick film bare gold electrode are compared with Scanning Electron Microscope (SEM). The electrochemical characteristics of the electrode during modification are studied with cyclic voltammetry technique. The results show that thick film electrode by screen printing technology is suited to the modification of molecular imprinting self-assembled film, and exhibits obvious amplification at nano level. The response of the sensor to the concentration of cholesterol is detected with chronoamperometric measurements. Cholesterol between 0 and 700 nM are detected with this sensor. The linearity range is from 50 nM to 700 nM with the sensitivity of -4.94 μA/lg(nM)] and linearly dependent coefficient of 0.994. And this cholesterol sensor has high accuracy, which reaches 99.56%.

Abstract: Cr2AlC bulk material was prepared insitu by hot pressing sintering using Cr3C2, Cr and Al as the starting materials. The samples were characterized using X-ray diffraction (XRD) and scanning electron microscope (SEM). The reaction process was investigated by means of differential scanning calorimetry (DSC). The corrosion properties of Cr2AlC in the acid and alkali solutions were obtained by weight loss method. The XRD result shows that high purity Cr2AlC bulk material can be synthesized by hot pressing with n(Cr3C2)∶n(Cr)∶n(Al)=0.5∶0.5∶1.2 at 1350℃ for 2h under 30MPa. The XRD patterns in different temperatures suggest that the reaction process of starting materials is that Al melts at first, then Cr5Al8 generates at 700℃, Cr2AlC is produced with the temperature elevation by the reaction of Cr5Al8 and Cr3C2 at last. SEM images of fracture faces of the sintered sample show the laminated and well plateshaped grains with a mean particale size of 6.4μm. Cr2AlC exhibits low weight loss except immersion in the concentrated H2SO4 and HCl solutions. The weight loss is negligible after immersing samples in the concentrated and dilute NaOH solutions for 150d and the corrosion rates are only 0.4 and 0.7μm/a, respectively.

Abstract: Xiaoyaosan (XYS) decoction is a famous prescription for the treatment of mental disorders in China. In this experiment, we explored the way in which XYS decoction-reverse hippocampus neuron apoptosis in vitro. We used XYS decoction-containing serum to treat oxidative-stress-induced hippocampus neuron apoptosis and used immunofluorescence to determine the concentration of free calcium, mitochondrial membrane potential, and apoptotic rate of neuron. Results showed that 3-hour oxidative stress decrease mitochondrial membrane potential, increase the concentration of free calcium and apoptotic rate of neuron via triggering pathological changes of nucleus such as karyorrhexis, karyopyknosis. Low, medium, high dose of XYS-decoction-containing serum could reverse these phenomenon, and the effect of low-dose XYS-decoction-containing serum was significant in improving mitochondrial membrane potential and apoptotic rate of neuron. These findings suggest that XYS decoction may be helpful in reducing oxidative-stress-induced hippocampus neuron apoptosis.

Abstract: From July 2009 to December 2009, 121 outpatients who presented to or were referred to the Department of Gastroenterology and Hepatology of the Chiayi Gung Memorial Hospital for evaluation of a complaint of EDS thought to be due to liver disease were examined. Demographic data were collected, and physical examinations and liver function tests were performed. Forty-eight patients had liver disease and were excluded. The Chinese Epworth Sleepiness Scale questionnaire (Chinese ESS) and the Chinese Gastroesophageal Reflux Disease Questionnaire (CGERDQ) were then administered to 73 included patients.More than half (56.2%) of the included patients were found to suffer from GERD. Patients with symptoms of GERD had higher mean CGERDQ scores than patients without symptoms of the disorder (18.88 ± 5.49 and 5.56 ± 3.57, respectively; P < 0.001). Patients with symptoms of GERD also had higher mean Chinese ESS scores than patients without symptoms (8.80 ± 5.49 and 3.13 ± 3.50, respectively; P < 0.001). Chinese ESS scores indicative of EDS were observed in 48.8% of patients with symptoms of GERD and in 3.1% of those without symptoms (P < 0.001). Differences between the two groups retained their significance after controlling for potential confounders.A significant percentage of Taiwanese patients who complained of EDS and were admitted to our Hepatology/Gastroenterology Department due to a suspicion of liver disease actually had symptoms of GERD. Further studies are needed to ascertain whether treatment of GERD will effectively resolve EDS in these patients.Gastroesophageal reflux disease (GERD) is a common disorder affecting approximately 10-38% of the adult population in Western countries and an estimated 17% of adults living in Xi'an, Shaanxi province in China [1-3]. Consequences of GERD include, but are not limited to, Barrett's esophagus and adenocarcinoma of the esophagus. In addition, GERD is associated with upper respiratory disease, adversely affects quality of life (QOL)
