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.

Objective To generate an autoimmune cholangitis animal model and investigate whether CXCR3 and its ligand were involved in the pathogenesis of primary biliary cirrhosis (PBC). Methods Female C57BL/6 wild-type (WT) mice and CXCR3 knockout (CXCR3-/-) mice were injected with 5 mg/kg of poly I:C intra-peritoneally twice a week for 24 consecutive weeks. Liver specimens were collected to evaluate the degree of cell infiltration. AMA was assayed by ELISA. Differences in pathology were compared between CXCR3-/- mice and wild-type. Student's test was used to assess the differences. Results Anti-mitochon-drial antibody (AMA) and alkaline phosphatase (ALP) level were elevated significantly in the sera of all poly Ⅰ:C injected mice compared with control mice. AMA titers in serum were increased in the poly I:C injected WT mice compared with that of the control mice at week 8, 16, and 24 respectively (0.70±0.41 vs 0.17±0.04,0.48±0.35 vs 0.19±0.07, 0.69±0.44 w 0.20±0.06, P＜0.01). There was no significant difference between AMA titers in the serum of WT PBC mice and CXCR3-/- PBC mice (0.70±0.41 vs 0.56±0.25, 0.48±0.35 vs 0.46±0.35, 0.69±0.44 vs 0.85±0.34). Serum alkaline phosphatase (ALP) levels were raised among the poly I:Cinjected WT mice compared with WT controls (115±33) vs (65±7) U/ml; (119±32) vs (70±9) U/ml; (133±52) vs (77±10) U/ml. The serum ALP levels in CXCR3-/- PBC mice were (106±29), (112±29)and (122±60) U/ml at week 8, 16 and 24 respectively. There was no significant difference in ALP level between WT and CXCR3-/- mice PBC model. Considerable numbers of infiltrating cells were detected at the portal areas 8weeks after poly I:C injection, which progressed up to 24 weeks. At week 24, the interlobular bile ducts were lost and bile-plug were evident. Compared to WT mice model, this results revealed that CXCR3-/- mice, had fewer foci of inflammation and significant reduction in total inflammatory cells in their livers than those of the WT mice at 8, 16 and 24 weeks after injection of poly I:C. At week 24, there were no cholestasis orgranulomas in CXCR3-/- mice of PBC models. Compared to the control model, CXCL10 serum level was increased in PBC model. With the disease progression, CXCL10 serum level was elevated gradually. In comparison with wild mice, CXCR3-/- mice model had a higher serum level of CXCL10. At week 24, there was significant difference of CXCL10 serum level between wild-type mice and CXCR3-/- mice model. Conclusion In conclusion, these findings indicate that, CXCR3-/- mice might have a delayed onset and ultimately could not recruit sufficient effector cells to the liver for inflammation development.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

OBJECTIVETo investigate clinical effects of strategy by stages for preventing respiratory complications of patients with acute cervical spinal cord injury (ACSCI).

METHODSFrom September 2009 to May 2013,the clinical data of 91 patients with ACSCI underwent surgery were retrospectively analyzed. Among the patients, 42 patients were divided into in-stages group, including 30 males and 12 females with an average age of 50 years old (ranged 28 to 76) which were treated with strategy by stages for preventing respiratory complications; others 49 patients which were not treated with the strategy regarded as control group, including 38 males and 11 females with an average age of 47 years old (ranged 30 to 77). All of them had definite history of trauma, and were admitted to orthopaedics within 48 h after trauma. In in-stages group, respiratory muscle strength training, high-dose ambroxol using and other treatment were performed to prevent respiratory complilcations according to preoperative, intraoperative and postoperative stage. While in control group, there were no systematic and effective measures utilized. Chi-square test was used to evaluate the difference for respiratory complications rate, the rate of tracheostomy or intubation and mortality caused by the respiratory complications between two groups.

RESULTSTen patients developed with respiratory complications in in-stages group (7 patients with pneumonia, 1 with atelectasis and 2 with respiratory failure), among which 3 patients underwent tracheostomy or intubation. In control group, 24 patients developed with respiratory complilcations (15 with pneumonia,3 with atelectasis and 6 with respiratory failure), among which 11 patients underwent tracheostomy or intubation. There was significant difference between two groups (χ2 = 6.12, 4.07; P = 0.013, 0.044). Five patients died because of respiratory complications, one case were in in-stages group and 4 in control group. There was significant difference between two groups (χ2 = l.39, P = 0.238).

CONCLUSIONThe strategy by stages is an effective method for preventing respiratory complications of ACSCI and can reduce the respiratory complications rate and improve the prognosis of respiratory complications.

OBJECTIVETo investigate the clinical effects of close reduction and minimally invasive percutaneous plate osteosynthesis in treating proximal humerus fractures in the aged.

METHODSFrom February 2012 to December 2013,39 patients with proximal humerus fractures were treated with minimally invasive percutaneous plate osteosynthesis (MIPPO group, 21 cases) and open reduction internal fixation (ORIF group, 18 cases). Including 17 males and 22 females in the study, and aged from 67 to 88 years old with an average of (71.8 ± 5.2) years old. In MIPPO group, there were 11 males and 10 females with an average age of (70.0 ± 5.3) years old;and in ORIF group, there were 10 males and 8 females with an average age of (72.0 ± 4.2) years old. Operation time, blood loss during operation, fracture healing time and postoperative complications were recorded. The functions of the shoulder joints were assessed according to Constant-Murley score at final follow-up.

RESULTSAll the patients were followed up from 11 to 27 months with an average of 18.1 months. The mean blood loss of the MIPPO group was (176.0 ± 57.4) ml,while the ORIF group was (356.0 ± 66.9) ml (t = 7.22,P = 0.01). The operation time of the MIPPO group was (47.4 ± 14.9) min, while the ORIF group was (92.7 ± 15.8) min (t = 0.79, P = 0.03). Fracture healing time in the MIPPO group and ORIF group was (17.6 ± 5.8), ( 21.7 ± 4.9) weeks, respectively (P < 0.05). The mean Constant-Murley score at final follow-up was 89.7 ± 14.5 in MIPPO group, and 81.8 ± 13.2 in ORIF group (P < 0.05).

CONCLUSIONMIPPO has advantages of little trauma, less blood loss, rapid recovery, less vascular damage and so on and can effectively treat the proximal humerus fracture in the aged.

BackgroundBiological behavior of choroidal melanoma is closely related with angiogenesis.The microcirculation pattern in which tumor cells may be involved is different from neovascularization.ObjectiveThis study was to observe the microcirculation pattern of the choroidal melanoma tissue and analyze its relationship with the clinical pathology factor and the degree of cellular proliferation.Methods Forty-eight specimen of choroidal melanoma tissue were collected at Beijing Tongren Eye Centre from November 1997 through March 2006.Periodate acid Schiff staining was used to determine the microcirculation pattern of choroidal melanoma.The morphology of the tumor cells and the distribution of microcirculation pattern in the tumor were observed under a fluorescence microscopy with 544 nm wavelength,and the Ki-67 expression in the tumor was detected by immunochemistry.The relationships between the choroidal melanoma clinical pathology factor with Ki-67 expression and microcirculation pattern were evaluated by multiple stepwise regression model.ResultsA total of 9 kinds of microcirculation patterns were found by periodate acid Schiff staining.The occurring rate of loop- or network-like vascular pattern showed a significant elevation in the tumor tissue with epithelial cells in comparison with the tumor with spindle-like cells (66.7％ vs.30.6％ ) ( P=0.027 ).The expression rates of Ki-67 were 18.961 ± 10.995 and 19.481 ± 12.167 in the tumor tissue with loop- or network-like microvascular pattern,and those in the tumor tissue without loop- or network-like microvascular pattern were 10.261 ±5.669 and 12.021 ± 6.802,presenting significant differences between them ( P =0.000,P =0.010).Loop-like microvascular pattern was determined as the risk factor of the proliferation and metastasis of choroidal melanoma by multiple stepwise regression analysis (P=0.002).ConclusionsAmong the nine microcirculation patterns in choroidal melanoma,networks pattern is the most fashion,and Ki-67 expression is more strong in the tumor with epitheliod cells,suggesting that this microcirculation pattern is associated to the malignant degree and extent of proliferation in choroidal melanoma.

Objective To study the technique and clinical significance of percutaneous biopsy of transplanted liver guided by CT.Methods 19 transplanted liver were undergone 25 times of percutaneous biopsy and the pathomorphologic changes were demonstrated by HE staining.Results The successful rate of the percutaneous biopsy was 100% for all the 25 times of this procedure,including acute rejection on 9 episodes,preservation perfusion retrauma in 6,bile duct strictures in 4,drug-induced injury in 4,chronic rejection in 1 and acute hepatic necrosis in 1.Conclusions CT-guided percutaneous biopsy is an important method for diagnosing transplanted liver injury and providing great value for distinguishment of the causes for transplanted liver injury.(J Intervent Radiol,2007,16:855-857)

Objective The aim of this phase Ⅱ study was to determine the efficacy and safety of combined bortezomib and thalidomide (VT) regime as initial treatment for newly diagnosed multiple myeloma (MM) in China. Methods Thirty-four patients were enrolled in this study and received VT regime up to 21-day cycles. Bortezomib (1.3 mg/m2) was administered intravenously on days 1, 4, 8, and 11, while oral thalidomide ( 100 mg/day) was given from days 1 to 21. The primary end point was clinical response.The secondary end point was safety. Results Among the 34 patients, 20 were male, 14 were female, with a median age of 59 years, and 15 in international stage system (ISS) Ⅲ ,18 in ISS Ⅱ , 1 in ISS Ⅰ . Among them, 28 completed 2 cycles' treatment and achieved an overall response rate (ORR) of 92.9%; 26 were able to complete the planned 8 cycles of therapy. After 8 cycles, the ORR was 100% ( complete response 30. 8%, near-complete response 23.1%, partial response 42. 3%, minimal response 3.8% ). After followed up with a median time of 12 months, the estimated rate without progress of disease was 62%, and the estimated continous remission rate of 12 months was 62%. The median survival time was not achieved. The most common adverse events were mild to moderate ( grades 1, 2). The main toxicities were hematologic (53. 3% ), gastrointestinal ( 40. 0% ), peripheral neuropathy ( 38.0% ), fatigue ( 36. 6% ) and fever (32. 0% ). Conclusions VT regime provides a very high ORR and complete response rate in the treatment of newly diagnosed MM patients. No patients experienced deep venous thrombosis. In conclusion,bortezomib in combination with thalidomide is a very effective regimen for newly diagnosed MM patients and the toxicities are manageable.

Objective As brucellosis epidemic is constantly rising in Harbin in recent years,we analyze the epidemic and surveillance results at municipal surveillance spots of brucellosis from 2008 to 2012,to find out the epidemic characteristics of Harbin brucellosis,and to provide scientific evidences for development of countermeasures.Methods Brucellosis surveillance data which were collected from the National Diseases Surveillance Information Management System from 2008 to 2010,the epidemic characteristics of Harbin brucellosis (including regional,time and population distribution) and the municipal surveillance results in Harbin (including epidemiological investigation and serological surveillance) were analyzed.Results A total of 1348 cases of brucellosis were reported in Harbin from 2008 to 2012,and the incidence of brucellosis increased from 1.79 per 100 000 to 4.62 per 100 000; in addition to Pingfang District (2008-2011) and Fangzheng County(2009 and 2011),all eighteen districts (counties or cities) in Harbin had reported epidemic in the past five years,the highest incidence was in Yilan (382 cases),and the incidence was significantly increased in Shuangcheng(111 cases) and Binxian(73 cases) in 2012; the time of onset focused on March to July,which accounted for 62.54％(843/1348) of annual incidence; age distribution,mainly young adults aged 30 to 60(71.59％,965/1348); gender distribution predominantly male (75.45％,1017/1348) ; occupational distribution farmers(84.87％,1144/1348),and the number of infected students and house workers were also high in the past five years(4.23％,57/1348 and 2.52％,34/1348).In the municipal surveillance spots from 2008 to 2012,13 010 cases were surveyed,of which 2695 cases received serological test,the positive rate was 3.93％ (106/2695),and the positive rate was increasing year by year.Conclusions The incidence of Harbin brucellosis is increasing year by year,onset season mainly in the spring and summer,young men with a high incidence,and farmers are main professional people.Brucellosis has also occurred among students,domestic workers,which should be vigilant.Therefore,we should further strengthen surveillance,timely analyze and report the epidemic,and provide a scientific basis to ensure each measure of eliminating the sources of infection put in place,vigorously develop health education,strengthen inter-departments cooperation,and control the spread of epidemic.

ObjectiveTo investigate the effects of imidapril on the transmural dispersion of repolarization of the noninfarcted myocardium of rabbits after myocardial infarction. MethodsRabbits with left coronary artery ligation were prepared and allowed to recover for 8 weeks. Monophasic action potentials of three layers myocardium in the noninfarcted myocardium in vivo were recorded. Myocytes were isolated from subendocardial, midmyocardial and subepicardial regions of the noninfarcted left ventricular wall and action potentials were recorded using whole-cell patch clamp technique. ResultsCompared with sham group, the monophasic action potential duration (MAPD90) of three layers myocardium were all prolonged. Prolongation of MAPD_ 90 of midmyocardial cell was the most striking and ventricular fibrillation threshold (VFT) was decreased. After treatment with imidapril, the transmural dispersion of repolarization (TDR) decreased and the VFT enhanced. ConclusionImidapril reduced the transmural dispersion of repolarization of noninfarcted area in rabbits after myocardial infarction, which may contribute to its antiarrhythmic efficacy.
