Objective To study the cytochemical changes of hepatocytes in mice exposed to hypoxia. Methods The mice were divided into two groups(n=45, all males, hypoxia group=36, control group=9). The mice of the hypoxia group lived in hypoxia (O 2:10%). Using imaging analytical instrument LEICA-500IW, We observed cytochemical changes of the hepatocytes. The PAS, LDH, cytochrome oxidase, Mg 2+ dependent ATPase activity of hepatocytes was assayed. Results Compared with the controls, the LDH activity of hepatocytes increased dramatically, the longer the hypoxic time, the higher the LDH activity of the hepatocytes; the cytochrome oxidase activity of hepatocytes decreased sharply, the longer the hypoxic time, the lower the cytochrome oxidase activity of the hepotocytes.Conclusion Hypoxia can injury the hepatocytes of the mice and result in sharp changes of the hepatic cytochemistry.;

This article was aimed to research the processing methods of Mongolian Meng-Gen-Wu-Su. Ancient and modern literatures which are related to the processing methods of Meng-Gen-Wu-Su were reviewed, summa-rized and sorted . The results showed that the traditional Mongolian Me ng-G e n-W u-Su processing method began in the eighteenth century in the book of Bi Y ong Y ao Ji Zhu Pin . The processing methods of all previous dynas-ties can be classified into three steps, which are descaling, detoxicating and specific drug processing. The pro-cessing methods contain soft, heat, cold, even, obvious, fierce, slow, white, black, speed and hard method. Among these 11 kinds of processing methods from all previous dynasties, some of them use the same processing name but the processing method are different; and some of them use different processing name but the processing methods are the same. Hence, there are 7 kinds of processing methods according to the processing content. Among them, the sulfur processing of Me ng-G e n-W u-Su is widely applied . This processing method is still used today and it can be divided into two kinds, which are the heat process and cold process. This method was originated from the fierce processing and even processing method in the book of Gan Lu Si Bu. And steps of descaling and detoxicat-ing in the processing are ignored. Other processing methods have rarely been used or not used at all. It was con-cluded that the sulfur processing method of Mongolian Me ng-G e n-W u-Su is still used until now .

Meng-Gen-Wu-Su (mercury)-18-composition pill was firstly recorded in the book of Gan-Lu-Si-Bu with the name of Jin-18 pill . The name of Me ng-G e n-W u-Su ( mercury )-18-composition pill was firstly recorded in the book of Me ng-Y i-Jin-G ui . Its composition and dosage had always been adjusted in the later dynasties . Until the issue of the book Ne i-Me ng G u-Me ng Che ng-Y ao Biao-Zhun , the composition and dosage of Meng-Gen-Wu-Su was promulgated. In different periods, the Meng-Gen-Wu-Su consisted of 17, 18 or 19 kinds of herbs. There are at least five different types of herbs appeared in the Meng-Gen-Wu-Su-18-composition pill. But 16 kinds of medicinals such as mercury, He-Zi, Cao-Wu, Liu-Huang, Qing-Ma-Zi, Jue-Ming-Zi, Bai-Yun-Xiang, Mu-Xiang, Shi-Chang-Pu, Su-Ge-Mu-Le, Shi-Gao, Rou-Dou-Kou, Ding-Xiang, Cao-Guo, Hong-Hua, Hei-Yun-Xiang are fixed in the composition. The proportion of Meng-Gen-Wu-Su-18-composition pill is inconsistent in different periods. The significant difference of drug dosage proportion are Liu-Huang and Bai-Yun-Xiang, followed by Qing-Ma-Zi, Jue-Ming-Zi, Cao-Guo, Wen-Guan-Mu. The Meng-Gen-Wu-Su-18-composition pill and Jin-18 pill from the book of Gan-Lu-Si-Bu are same prescription with the same composition but different names. The composition and dosage proportion of Meng-Gen-Wu-Su-18-composition pill from the book of Meng-Yi-Jin-Gui and He-Li-Le Jing-Zhu Jie-Y i Nan-Jing are the same with the same prescription name .

Objective:To explore the relationship between anxiety and mental resilience of caregivers for community-dwelling dementia patients.Methods:Patients in four communities who met the diagnostic criteria for Alzheimer's disease(AD)were randomly selected and their caregivers served as study subjects.General characteristics, anxiety and resilience of caregivers(n=592)were investigated with a questionnaire developed by ourselves, the Generalized Anxiety Disorder-7 Scale(GAD-7), and the Conner-Davidson Resilience Scale(CDRISC).Results:There were 592 subjects in the study, with 185 cases(31.3%)having anxiety.Differences in manifestations of anxiety existed between caregivers for AD patients in different age groups( P<0.01). Anxiety levels were also influenced by AD patient caregivers' gender, educational level and blood relationship to the patient( P<0.05). The differences were reflected in tenacity( F=72.58), strength( F=82.19), optimism( F=12.57)and the total elasticity score( F=162.88). The Spearman correlation was used to analyze the association of caregiver anxiety with caregivers' general characteristics and domains of psychological resilience.The results showed that anxiety was negatively correlated with gender( r=-0.09, P<0.05), education level( r=-0.112, P<0.01), blood relationship( r=-0.122, P<0.01), psychoelasticity and three other domains( r=-0.457, -0.495, -0.208, -0.60, all P<0.01), but was positively correlated with age( r=0.127, P<0.01). Logistic regression analysis showed that psychoelasticity was a protective factor for anxiety in caregivers for community-dwelling AD patients( β=-0.323, P<0.05). Conclusions:While treating Alzheimer's patients, clinicians can consider psychotherapy measures to improve the psychological resilience of their caregivers.

OBJECTIVETo detect and study the types of Borrelia burgdorferi sensu lato in ticks and rodents from Da Xing-An Mountains Forest areas of China.
METHODSNested PCR was performed to amplify 5S-23S rRNA intergenic spacer of B. burgdorferi. Positive products were analysed by restriction fragment length polymorphism (RFLP) and single strand conformation polymorphism (SSCP), specimens showing unique RFLP profile were sequenced and analysed.
RESULTS1336 Ixodes persulcatus, 144 Dermacento silvarum, 144 Haemaphysalis concinna and 145 rodents of 9 species were collected from 16 sections of Da Xing-An Mountains Forest areas of China. Specific fragments were amplified from 293 I. persulcatus and 6 D. silvarum and 5 rodents of 4 species. B. burgdorferi was not detected in H. concinna. Among the positively tested I. persulcatus, 209 contained B. garinii genospecies and 45 contained B.afzelii genospecies based on RFLP. Moreover, B.garinii genospecies consisted of B. garinii 20047 and B. garinii NT29. 17 adult I. persulcatus were simultaneously infected with B. garinii 20047 and B. garinii NT29. Nine adult I. persulcatus were simultaneously infected with B. garinii 20047 and B. afzelii. Four adult I. persulcatus were simultaneously infected with B. garinii 20047 and B. garinii NT29 and B. afzelii. Two D. silvarum were infected with B. garinii 20047, 1 D. silvarum with B. garinii 20047, 2 D. silvarum with B. afzelii. 3 rodents were infected with B. garinii 20047 while 2 rodents were infected with B. garinii NT29. Mixed infection was not found in D. silvarum and rodents. In addition, nine I. persulcatus and one D. silvarum specimens showed unique RFLP pattern. Data from sequential analysis showed that they all belonged to B. garinii. PCR-SSCP profiles of 5S-23S rRNA intergenic spacer of B. burgdorferi in the positive specimens exceeded 36 types; B. garinii 20047 showed 16 types while B. garinii NT29 showing 11 types, B. afzelii showing 9 types. SSCP profiles of the specimens coinfected with multiple B. burgdorferi was relatively complex.
CONCLUSIONThe infection of B. burgdorferi was found in the ticks and rodents in Da Xing-An Mountains Forests areas. The infection rate of I. persulcatus was high. B. garinii was predominant genospecies, and the population of B. burgdorferi was heterogeneous in the area. Mixed infections of different B. burgdorferi genospecies in ticks were found. I. persulcatus and Clethrionomys rufocanus were possibly served as major vector and major host for B. burgdorferi, respectively, suggesting that further study is needed to confirm the coinfection in humans and animals in this region.

OBJECTIVETo investigate the prevalence of Anaplasma phagocytophilum in rodents from forest areas in northeastern China.
METHODSPCR amplification, followed by sequence analysis was carried out. The sequences of 16S rRNA and gltA gene fragment amplified from rodent specimens were compared with corresponding part of the sequences deposited in GenBank.
RESULTSA total number of 276 rodents were tested, including 102 in Jilin province, 61 in Helongjiang province and 113 in Inner Mongolia autonomous region. The positive rates were 8.82%, 1.64% and 0.00%, respectively. The infection rate in rodents infected by ticks was 11.30 times higher than that in rodents without ticks (P = 0.002). The S. A. phagocytophilum 16S rRNA sequences from rodents in Jilin and Heilongjiang were identical and differed in 3-5 bases compared with the corresponding parts of A. phagocytophilum from America, Sweden and Japan. Compared with the sequences registered in GenBank, the nucleotide sequence of gltA varied from 87%-97% and its deduced amino acid sequence changed from 84%-99%.
CONCLUSIONA. phagocytophilum infection was presented in rodents from Jilin and Heilongjiang province.
