Rheumatoid arthritis (RA) is a kind of chronic, progressive, multiple, invasive autoimmune disease with two chief cclinical manifestations arthrosynovitis and ex-arthrosis, easy to occur in middle-aged women, also occur in children and the elderly, is characterized by progressive and break out repeatedly. RA pathogenesis is complex, there is no special treatment, used in treatment of R drug varied, new drugs and new therapies also emerge in endlessly, main including non-steroidal anti-inflammatory drugs (NSAIDs), slow action anti-rheumatism medicine (SAARDs), glucocorticoids (GCs), biological agent, traditional Chinese medicine and traditional Chinese medicine preparations, domestic market for rheumatoid main drug treatment are NSAIDs, SAARDs, GCs, traditional Chinese medicine and traditional Chinese medicine preparations. Traditional Chinese medicine and traditional Chinese medi- cine preparations for the treatment of RA have its unique advantages, show the characteristics of overall adjustment, multi-level and multiple targets, and also can alleviate and against side effects of western medicine. In recent years, more and more get people's atten- tion. This paper reviewed the research progress and treatment features of commonly used therapeutic agents for the treatment of RA in recent years, which provides reference and basis for future medicine anti-RA.

OBJECTIVETo observe the effect of Yangxue Qingnao Granule (YQG) on the expression of CD11b in CA1 region of hippocampus of vascular dementia rats, and to explore its regulation on microglias.

METHODSTotally 144 SD rats were randomly divided into the sham-operation group, the vascular dementia model group (model), and the YQG treated group (treated). The vascular dementia rat model was prepared by modified Pulsinelli's four-vessel occlusion. Rats in the sham-operation group and the model group were administered with normal saline -(at the daily dose of 10 mL/kg) by gastrogavage, while those in the treated group were administered with YQG (0.32 g/mL, at the daily dose of 10 mL/kg) by gastrogavage. All administration was performed once per day for 8 successive weeks. The expression of CD11b in CA1 region of hippocampus of vascular dementia rats was detected at week 1, 2, 4, and 8, respectively.

RESULTSCompared with the sham-operation group, the expression of CD11b in CA1 region of hippocampus of vascular dementia rats were significantly enhanced in the model group at each time point (P < 0.01). Compared with the model group, the expression of CD11b in CA1 region of hippocampus of vascular dementia rats significantly decreased in the treated group at each time point (P < 0.01), especially at week 2.

CONCLUSIONObvious activation and proliferation of microglias could be seen in CA1 region of hippocampus of vascular dementia rats, and YQG could inhibit activation and proliferation of microglias.

Objective To observe the changes of the peripheral blood T lymphocyte subsets following acute spinal cord injury and investigate the possible mechanism of these changes. Methods The SCI models of rats were made by Allen's method. Forty SD rats were divided into four groups, ie,normal control group, sham operation group, 100 g·cm group and 200 g·cm group. The expressions of CD4 and CD8 subsets of the peripheral blood T lymphocyte of the injured rats were determined by immunofluorescence labelling and flow cytometry at different times after injury. Results It was found that the expression of CD4 was significantly reduced to (30.40±4.76)% in 100 g·cm group and to (26.54± 9.34) % in 200 g·cm group, which were significantly lower than that of normal control group ( P ＜0.01 ). At 36 hours after injury, the ratio of CD4/CD8 was significantly reduced to 1.81 ± 0.55 in 100 g·cm group and and 1.29 ± 0.50 in 200 g·cm group, with statistical difference (P ＜ 0.05).Conclusions The immunoreaction is significantly depressed at the early stage of acute spinal cord injury. The severer injury results in more significant decrease of CD4 and ratio of CD4/CD8. The changes of CD4 and CD4/CD8 ratio can be used to indicate the severity of spinal cord injury.

BACKGROUND:Restenosis after angioplasty severely limited the application and long-period therapeutic effects of percutaneous coronary intervention. Changes in smooth muscle cel phenotype and their proliferation are important mechanisms of restenosis after angioplasty.
OBJECTIVE:To use bal oon in vivo transduction of osteopontin short hairpin RNA (OPN-shRNA), to inhibit osteopontin expression at the injured blood vessels of a rabbit model of experimental atherosclerosis, and to prevent restenosis after angioplasty.
METHODS:A total of 20 rabbit models of atherosclerosis were established and randomly equal y assigned to empty plasmid group and OPN-shRNA plasmid group. The plasmid recombinant OPN-shRNA and empty plasmid were transferred to the ventral aorta by bal oon.
RESULTS AND CONCLUSION:After bal oon dilatation, specific green fluorescence was detected in the layer of vascular smooth muscle in the two groups. Moreover, with prolonged time of transfection, fluorescence intensity gradual y decreased. Compared with the empty plasmid group, the expanded artery lumen area obviously increased in the OPN-shRNA plasmid group, and plaque burden evidently reduced. Results indicated that bal oon catheter used in regional blood vessels in rabbit models of atherosclerosis could successful y transduce OPN-shRNA plasmid. The restenosis of the expanded blood vessels lessened, and thrombus burden relieved. It is of great importance to prevent the occurrence of restenosis after angioplasty in rabbit models.

Objective To investigate the clinical characteristics in chronic severe hepatitis B patients with HbeAg-positive and HbeAs-negative.Methods A total of 95 chronic severe hepatitis B cases were retrospectively analyzed.The clinical information,hepatic function,hepatic fibrosis and HBV DNA in HBeAg-negative and HBeAgpositive groups were analyzed.Results of the 95 cases,54(57% ) were HBeAg-negative and 41(43% ) were HBeAg-positive.No significant differences were found on age,ALB,TB,CHE,indexes of hepatic fibrosis and the ratio of complications between HBeAg-negative group and HBeAg-positive group.Compared with HBeAg-positive group,there were significantly higher levels of ALT(198.25±215.37)U/L vs(400.37±413.59)U/L],AST[(254.78±269.16)U/L vs(578.14±600.23)U/L] and lower level of HBV DNA[(6.17×10~6±8.24×10~1)copies/ml vs (2.39×10~5±6.75×10~1) copies/ml] in HBeAg-negative group(P<0.05).The anteroposterior diameter of the left liver and the thickness of right liver were(65.12±12.43)mm and(95.37.±12.69)mm in the HBeAg positive fatal chronic severe hepatitis B before the terminal phase,vs(56.78±11.04)mm and(89.34.±9.23)mm in the HBeAg negative group,and the former is longer than the later(P<0.05).Conclusion Tissue injury is more serious and the level of HBV DNA is lower in HBeAg-negative patients than HBeAg-positive patients.Liver size of HBeAg negative group reduces more significantly than HBeAg positive group before terminal phase.

Objective To explore therapeutic effects and mechanisms of radical scavenger edaravone on experimental cerebral hemorrhage.Methods Two hundred-forty male SD rats were divided randomly into four groups:control group,cerebral hemorrhage group,edaravone treatment group before operation (A) and edaravone treatment group after operation (B).Experimental cerebral hemorrhage model was made according to the method reported by Rosenberg.Water quantity contained in brain and nervous missing sign were observed,meanwhile the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in brain tissue were measured.Results Compared with cerebral hemorrhage group,nervous missing sign and water quantity contained in brain obviously changed in edaravone treatment group (P

Objective:To study the relationship between dynamic Hoffmann's sign(DHS) and the early diagnosis of cervical spondylotic myelopathy. Methods:Patients with neck, shoulder and back pain (218 cases) were employed in this investigation. Among them, 96 cases had positive reaction to DHS test and they received 3 7 years follow up as study group. The other 122 cases negative to DHS test were taken as control group. The clinical data included the patient's symptoms and signs, sagittal diameter of cervical spinal canal, Pavlov rate, angular displacement and horizontal displacement between cervical vertebral, etc . Results:There were 72 cases in study group developed cervical spondylotic myelopathy and needed operation during follow up. Meanwhile, 11 cases in control group received surgical treatment. The incidence of stenosis of cervical spinal canal, herniation of cervical intervertebral disc and instability of cervical spine in DHS group were significantly higher than that of the control group. Conclusion:DHS is closely related to the onset of cervical spondylotic myelopathy. The patients should be followed up closely if they present positive reaction to DHS, and should be operated on early when their neurological symptom is progressing.
