Aim To establish and evaluate the simple and effective animal model of rheumatoid arthritis in SD rats induced by heat-killed mycobacterium tuberculosis H37Ra(Mtb).Methods SD rats were immunized s.c.at the base of the tail with Mtb(1 mg/rat) in mineral oil,and then body weight,blood routine,clinical signs of arthritis were observed regularly.And also hind paw volume in SD rats with AA was tested.Meanwhile,T-lymphocyte subset was determined by flow cytometry in peripheral blood,the level of TNF-?in serum and IL-1 and IL-6 and vascular endothe-lial growth factor(VEGF) in joint tissue were tested by ELISA.The ankle pathological change and radiographic evidence of the hind paws of SD rats were observed to evaluate the AA model effects and availability in SD rats.Results When compared with normal control rats,the total number of white blood cells,platelets and monocytes in peripheral blood and ratio of CD4/CD8 was markedly raised after immunization with Mtb.But body weight of model rats was significantly low from day 14 to 28 after injection of Mtb.The inflammatory arthritic lesions such as edema and erythema in the paws appeared after 9~10 d.The peak of inflammation was 14~16 d.The level of TNF-?in serum and IL-1,IL-6 and VEGF in joint tissue was significantly higher in SD rats with Mtb than that in normal control rats at d 28.The histopathological examination revealed cellular infiltration,synovial and cartilage hyperplasia in ankle joints of SD rats.Conclusions The model induced by Mtb in SD rats is more similar in clinical characterization of rheumatoid arthritis in human being.It is a more efficient and simpler manipulative procedure for screening of new anti-arthritis drugs and experimental studying of anti-rheumatoid arthritis.

Considering the fact of rapidity and concentration of aging of population, Chinese government has regarded it as an important strategic issue. However, how to get a dignified ending still a big problem for the old age today. This article tries to explore the possibility of advance care planning (ACP) approved under the background of aging of population in China based on general report of Chinese government deal with aging of population and existed facts. Though the researches on this topic have grown rapidly, the government legal system is still close to it in this moment, and in the process of practice constantly, it will be a perfect research. It is certain that the legislation of ACP in China will has a long way to go, but in the view of the advancement of death with dignity, palliative care, we still can predict a bright future of ACP.

In order to search for a more potent and less toxic antifungal agent, five novel sulconazole analogues were synthesized by changing 1-imidazolyl and p-chlorobenzyl in sulconazole structure. The results of preliminary biological tests show that analogues Ⅰ and Ⅱ possess more potent antifungal activities and wider antifungal spectra than sulconazole.

Acupoint compatibility is a basic element for acupuncture prescription and an important link for clinical acupuncture workers to obtain a therapeutic effect. Studying factors influencing the effect of acupoint combination and ascertaining its concept and connotation are of important significance for studying the mechanism of acupuncture action. By sorting out, summing up and analyzing relevant modern literature, it is found that factors influencing the effect of acupoint combination are those affecting the therapeutic effects of combination of two or more than two acupoints. Its contents include five aspects: combination mode, combination effect, stimulation method, time factor and body status. Analysis and induction show that acupoint selection is the primary task in studying factors influencing the effect of acupoint combination.

Primary insomnia (PI) is now a nonorganic sleep disorder that seriously affects the quality of life of people around the world and attracts the attention of medical circles at home and abroad. Western medicine treatment has side effects such as drug dependence and withdrawal rebound and cannot obviously improve the quality of sleep and life, while acupuncture has a good therapeutic effect on PI. This article explores the latest research status of acupuncture treatment for PI. Chinese Journal Net (CNKI, VIP and Wanfang) was mainly searched to retrieve and sum up recent five years’ literature about the study of acupuncture treatment for PI. The results show that acupuncture has an advantage in producing a short-term marked therapeutic effect on PI and being of a high total efficacy rate and can effectively treat primary insomnia.

Objective To study the effect of high intensity focused ultrasound(HIFU)ablation on microvessel density(MVD)and vascular endothelial growth factor(VEGF)in rabbit hepatcocellular carcinoma (HCC)models.Methods The VX2 t umor cells were planted in the hepatic left-central lobe on 30 rabbits.All animals were divided into two groups randomly:HIFU group(n=25)and control group(n=5).The MVD and the expression of VEGF in the HCC was detected by immunohistochemical SABC methods in control group and 0,1,3.7,16 d after the operation in HIFU group.Results The MVD and the expression of VEGF in the HCC tissue after HIFU treatment in the HIFU group were decreased significantly as compared with those in the control group (P<0.01).However,there was no significant difference in MVD and the expression of VEGF in the HCC tissue after HIFU treatment in the HIFU group among the different time points(P>0.05).Conclusions HIFU treatment can effectively destroy the micovessel,repress the neovascularization and reduce the blood supply of the HCC.

BACKGROUND:C2 transpedicle screw fixation for Hangman fractures has been paid more attention due to reliability and no loss of physiological function.However,there are lacks of biomechanical evidences for indication treatment because the fixation is single segmental.OBJECTIVE:To investigate the biomechanical stability of C2 transpedicle screw fixation for Hangman fractures.DESIGN,TIME and SEITING:This was a contrast study which was performed at the General Key Laboratory of Biomechanics,First Military Medical University of Chinese PLA from May to August 2004.MATERIALS:AO-universal titanium alloy transpedicle screw of 18 25 mm in length and 3.5 mm in diameter was adopted in this study.Six fresh C1-C4 cervical vetebrae samples were ordiually made into type Ⅰ,ⅡA,and Ⅱ Hangman fracture models.METHODS:After transpedicle screw fixation.Hangman fracture models were measured by non-destroyed style with spinal anterior flexion/posterior extension,left/right lateral curvature,and left/right axial direction.Loading/unlonding circulation was performed three times during each testing.Kinematics indicators were measured on the 3rd circulation.MAIN OUTCOME MEASURES:Spinal motor images at zero load and maximal load were obtained with laser photoscanning(0.1% in precision),and the corresponding systematic software was adopted to calculate 3D range of movement.RESULTS:The relative stability of type Ⅰ Hangman fracture models after C2 transpedicle screw fixation was 100.62%(inflexion),96.91%(posterior extension),99.19%(lateral curvature),and 97.12%(rotation)as compared to control group (P>0.05).The relative stability of type Ⅱ Hangman fracture models after C2 transpedicle screw fixation was 47.84%(inflexion),21.29%(posterior extension),65.98%(lateral curvature),and 41.69%(rotation)as compared to control group (P<0.05).CONCLUSION:Biochemical evaluation suggests that type Ⅰ and Ⅱ A Hangman fractures do fit for C2 transpedicle screw fixation,and the fixation may generate well physiological fixation or stability.However,stability of type Ⅱ Hangman fracture is poor,so it is not suitably adopted single transpedicle screw fixation.
