Medical Journal of Chinese People's Liberation Army , 2011,
Abstract: Objective To investigate the incidence and clinical features of allergic rhinitis in servicemen of Chinese People’s Armed Police Force stationed at Urumqi,Xinjiang Uygur Autonomous Region.Methods Of 2294 soldiers and officers stationed at Urumqi from Jul.to Aug.2010,2194 were enrolled as subjects of present study,and all of them completed the questionnaires.The incidence of allergic rhinitis was assessed by history analysis,skin fast prick and allergen-specific IgE assay.Results Two hundred and three cases were diagnosed as allergic rhinitis,the overall incidence was 9.3%.The incidence of allergic rhinitis was higher in officers(15.9%) than in soldiers(P < 0.05);seeds of Artemisia was the main allergen.Duration of service was positively correlated with the incidence of allergic rhinitis(r=0.8,P < 0.05).The incidence was also correlated with the place the servicemen stationed,showing a high to low tendency from suburbs(15.8%),forested area(7.9%) to urban area(5.7%,P < 0.05).The incidence was higher in servicemen from other regions(9.4%) than in soldiers of local origin(7.2%,P < 0.05),and was higher in Han nationality(10.5%) than in ethnic minorities(2.1%,P < 0.05).Conclusions The incidence of allergic rhinitis in servicemen of Chinese People’s Armed Police Force stationed at Urumqi is 9.3%,and and the incidence varies with the loeality they station.The severity of allergic rhinitis symptom is positively correlated with the duration of service in Urumqi.

Ab initio calculations of electronic structure of anatase TiO2
Chen Qiang,Cao Hong-Hong,

中国物理 B , 2004,
Abstract: This paper presents the results of the self-consistent calculations on the electronic structure of anatase phase of TiO_2. The calculations were performed using the full potential-linearized augmented plane wave method (FP-LAPW) in the framework of the density functional theory (DFT) with the generalized gradient approximation (GGA). The fully optimized structure, obtained by minimizing the total energy and atomic forces, is in good agreement with experiment. We also calculated the band structure and the density of states. In particular, the calculated band structure prefers an indirect transition between valence and conduction bands of anatase TiO_2, which may be helpful for clarifying the ambiguity in other theoretical works.

Histochemistry and cytology of the mucosa of small stomach in Alligator sinensis

Acta Zoologica Sinica , 2008,
Abstract: The small stomach of Alligator sinensis is a small cavity at the juncture of the stomachus pyloricus and duodenum enclosed by pyloric and duodenal circular sphincter. Its physiological function is still unclear. The histochemical components, ultrastructure and cell types of the small stomach were studied with histochemical, electron microscopic and immunohistochemical techniques. The epithelium in all parts of small stomach showed a strongly positive PAS-reaction and weakly AB staining, secreting mainly neutral mucopolysaccharide and a small amount of sulphur acidic mucopolysaccharide. The epithelium of small stomach was formed by surface mucous cells, containing few endocrine cells. Three types of cells including endocrine cell, glandular mucous cell and oxynticopeptic cell were observed in the gastric gland region, 70%–90% of which were endocrine cells. Six types of endocrine cells were detected by immunohistochemical method using seven antisera of gut hormones. They were 5-Hydroxytryptamine(5-HT), gastrin(Gas), glucagon (Glu), substance P(SP), somatostatin(SS) and vasoactive intestinal peptide (VIP) cells respectively. The density of Glu cells was the highest and the density of VIP cells was the lowest, no pancreatic polypeptide(PP) cells were detected. The results of this study suggested that, in terms of histochemical components and cell types, the small stomach of Alligator sinensis is homologous to its stomach; Considering the ultrastructure of oxynticopeptic cells and the percentage of endocrine cells, no tubulovesicle was observed in the oxynticopeptic cells, the percentage of endocrine cells was very high, the small stomach had been specialized, it might not secret gastric acid and may play an important role in the regulation of gastrointestinal function [Acta Zoologica Sinica 54(6):1044 –1050, 2008].

腐蚀科学与防护技术 , 2012,
Abstract: The Ni-nano Al2O3 composite plating was prepared on SUS304 stainless steel. The distribution of Al2O3 particles in the composite plating was examined. The proper amount of particles in the solution, current density as well as stirring speed for electroplating was then determined. Scanning electron microscope (SEM) and X-ray diffraction (XRD) were used to characterize the microstructure, composition and phase constituent of the plating. The results showed that the Ni-Al2O3 composite plating was very compact with small grain size, good adhesive to the substrate and excellent corrosion resistance. Furthermore the high-temperature oxidation resistance of the composite plating was higher than that of the Ni plating.

Abstract: Objective: Danggui, the root of Angelica Sinensis, has traditionally been used for the treatment of women’s reproductive disorders in China for thousands of years. This study was to determine whether Danggui have potential anti-cancer effect on women’s cancer and its potential mechanism. Methods: Danggui was extracted by ethanol. The Cell Titer 96 Aqueous Non-Radioactive Cell Proliferation Assay was used to compare the effects of Danggui on human breast (MCF-7 and 7368) and cervical (CaSki and SiHa) cancer cells with its effects on normal fibroblasts (HTB-125). A revised Ames test was used to test for antimutagenicity. The standard strains of Salmonella typhimarium (TA) 100 and 102 were used in the test. Methyl methane sulfonate (MMS) and UV light were used as positive mutagen controls and ethanol and double distilled water (DDW) as controls. The SAS statistical software was used to analyze the data. Results: Danggui was found to be much more toxic to all cancer cell lines tested than to normal fibroblasts. There was a significant negative dose-effect relationship between Danggui and cancer cell viability. Average viability of MCF-7 was 69.5%, 18.4%, 5.7%, 5.7%, and 5.0% of control for Danggui doses 0.07, 0.14, 0.21, 0.32, and 0.64 ug/ul, respectively, with a Ptrend < 0.0001. Half maximal inhibitory dose (ID50) of Danggui for cancer cell lines MCF-7, CaSki, SiHa and CRL-7368 was 0.10, 0.09, 0.10 and 0.07 ug/ul, Functional Foods in Health and Disease 2012, 2(6):242-250respectively. For the normal fibroblasts, ID50 was 0.58 ug/ul. At a dose of 0.32 ug/ul, Danggui killed over 90% of the cells in each cancer cell line, but at the same dose, only 12.3 % of the normal HTB-125 cells were killed. Revertants per plate of TA 100 decreased with the introduction of increasing doses of Danggui extracts with a Ptrend < 0.0001 when UV light was used as a mutagen. There was no difference in revertants per plate between ethanol and DDW control groups. Conclusions: Danggui could be used as a safe and effective adjuvant therapy to prevent and treat breast and cervical cancers. Anti-cancer effects may be due to its anti-mutagenicity. Danggui should be investigated as a potential adjuvant anti-cancer therapy for women’s cancer treatment and prevention of recurrence.
