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 investigate the long-term outcome of anterior decompression and bone graft fusion for cervical spondylotic myelopathy(CSM) and factors affecting the outcome. Methods: Two hundred and forty-five patients with CSM were treated with anterior cervical decompression and auto iliac bone graft fusion, of whom 31 had a second operation between 4 months and 2 years after operation. Follow-up studies were carried out within 5 to 15 years after operation, averaging 6.8 years. Results: Function evaluation: excellent in 118 cases (48.16%), good in 71 (28.98%), passable in 35 (14.29%) and poor in 21 (8.57%). According to the 40 points score method, there was an average of 8 point increase in all cases, of which 101 were between 36 to 40 points, 54 between 31 to 35 points. Conclusion: The long-term outcome of surgical treatment for CSM is definite. Significant factors affecting the outcome include timing of operation, degree of pathology and technique of surgery.

Objective To evaluate the effectiveness of one-stage debridement for cervical tuberculosis at different segments.Methods Clinical data of 54 patients (male 20,female 34) with cervical tuberculosis treated by one-stage debridement from Jan 1998 to Dec 2011 were reviewed retrospectively.The average age of these patients was 45.4 years (range,26-75 years).Among them,12 cases were involved in single level (C2 1 case,C4 2 cases,C5 3 cases,C6 4 cases,C7 2 cases); 36 cases in the adjacent two levels (C1,2 3 cases,C2,3 2 cases,C3,4 5 cases,C4,5 6 cases,C5,6 14 cases,C6,7 5 cases,C7T1 1 case); 5 cases in three levels(C4 6 2 cases,C5-7 2 cases,C3,5,6 1 case)and 1 case in four levels (C4-7).Five cases were involved in other spinal levels (T6 1 case,T 3 cases,L3,4 1 case).Comorbidity of cervical ossification of the posterior longitudinal ligament was found in 1 case.Before surgery,the mean VAS and JOA scores were 5.9 (range,4-9) and 10.5 (range,7-12) respectively and the mean Cobb angle of lesion segment was 26.7°± 9.1°.All cases underwent regular anti-TB treatment preoperatively,and surgical treatment were performed when blood sedimentation (ESR) was lower than 50 mm/1 h.According to the segmental involvement,different surgical approaches were performed including anterior debridement with anterior or anterior-posterior internal fixation and fusion,submandibular approach debridement with posterior occipital cervical fusion or atlantoaxial fusion.Results Mean follow-up duration was 27.3 months (range,13-52 months).Symptoms were improved significantly in all cases.Mean time of union was 3.2 months (range,2-4 months).At the last follow-up,the mean VAS and JOA scores were 5.9 (range,4-9)and 10.5 (range,7-12) respectively,and the mean Cobb angle of lesion segment was 6.8°.Regular anti-TB treatment was performed postoperatively for 18 to 20 months.Intraoperative esophageal injury was found in one case of upper cervical tuberculosis which was cured uneventfully after gastrointestinal tubation for 1 week.No cervical tuberculosis recurrence,graft loosening or pseudarthrosis was found in follow-up.Conclusion With preoperative anti-TB treatment,cervical tuberculosis can be treated by one-stage foci debridement according to the segmental involvement and deformity.Postoperative regular anti-TB treatment is a crucial factor for the final recovery of cervical tuberculosis.

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 review the relevant causes for and treatment of nerve injuries in the anterior cervical surgery. Methods From January 2008 to December 2009,859 cages of cervical spondylosis,ossification of cervical posterior longitudinal ligament and cervical spine trauma were treated by anterior cervical surgery.This study retrospectively analyzed the clinical data of seven cases who were with worsened symptoms of spinal cord injury and related nerve injury. Results Of 859 cases,five cases(0.58%)were with spinal cord injury,one(0.12%)with recurrent laryngeal nerve injury and one (0.12%)with laryngeal nerve injury.Hematoma occurred in four cases after surgery caused spinal cord injury and all the four patients recovered to normal after removal of the hematoma and timely treatment with mythylprednisolone and hyperbaric oxygen.Cervical spine trauma was worsened in one patient after the anterior cervical surgery.The patient restored to its original level of spinal cord gradually through some measures such as tracheotomy,ventilator support,hormone therapy and hyperbaric oxygen treatment.Laryngeal nerve injuries in two cases recovered to normal after conservative treatment with hormone,dehydration and other drugs within three months after surgery. Conclusions Anterior cervical surgery of cervical spondylosis,ossification of cervical posterior longitudinal ligament and cervical spine trauma are likely to induce the related nerve damage.The good prognosis can be obtained under timely prevention and treatment.

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.
