Objective To investigate the clinical efficacy of Bushen Tongdu Capsule for treating patients with rheumatoid arthritis (RA, TCM syndrome of kidney-deficiency with cold). Methods Totally 71 RA patients were randomly divided into treatment group (36 cases) that was treated with Bushen Tongdu Capsule and control group (35 cases) that was treated with tripterygium glycosides tablet. Both groups were treated for 12 weeks. The signs and symptoms, the state of illness, and laboratory index were observed before and after treatment. Results The total effective rate was 72.22% (26/36) in the treatment group, and 62.86% (22/35) in the control group, without statistical significance (P>0.05). After treatment, simplified disease activity index, TCM syndrome integrals, tender joint count, swollen joint count, overall evaluation from patients, overall disease evaluation from doctors, rest pain, morning stiffness time, average hands grip strength, 20 m walking time, healthy condition questionnaire score, and C-reactive protein were significantly improved in both groups (P<0.01, P<0.05). Compared with control group, TCM syndrome integrals changed more significantly, with statistical significance (P <0.05). Conclusion Bushen Tongdu Capsule can relieve symptoms and signs of RA patients (TCM syndrome of kidney-deficiency with cold) effectively.

Many microbial pathogens,including those responsible for major enteric infections,exploit oligosaccharides that are displayed on the surface of host cells as receptors for toxins and adhesins. Blocking crucial ligand receptor interactions is therefore a promising therapeutic strategy. One approach is to express molecular mimics of host receptors on the surface of harmless recombinant bacteria that can survive in the gut. These recombinant probiotics bind bacterial toxins in the gut lumen with very high avidity,thereby preventing disease.

Fermentation property and kinetic analysis of the inhibition of in vitro growth of pathogenic Escherichia coli K88, O138 by Lactobacillus intestinalis isolated from porcine intestine mucus were investi-gated. The results of fermentation showed that L1 result in a pH of 3.90 within 12 h and a large amount of lactic acid production, with the concentration of 104.08 mmol/L. Kinetic analysis of the antibacterial activity of L1 metabolic product toward K88, O138 showed that CFUS display strong antibacterial activity toward K88, O138; the antibacterial activity of L1 CFUS was higher than the lactic acid control samples and was mainly due to the production of lactic acid; K88, O138 had the tolerance property toward pH 4.5.

Objective To understand the situation of oxidative stress among diabetic nephropathy (DN) patients and observe the antioxidative effect of losartan at increasing dose in DN patients. Methods Thirty type 2 DN patients who neither smoked and nor took antioxidants were selected. The study began with an initial 4-6 weeks screening-treatment. Eligible patients then received losartan 50 mg/d daily for 8 weeks followed by losartan 100 mg/day daily for an additional 8 weeks. Blood glucose and blood pressure were closely monitored over the whole study period. All patients were followed up every other weeks, their 24-hour urine samples,fresh urine and venous blood sample were collected to measure urinary protein and creatinine excretion, urinary 8-OHdG, SOD, TAOC and MDA excretion , serum SOD, TAOC , MDA and other blood biochemistry parameters. Urinary 8-OHdG was determined by capillary electrophoresis and liquid phase chromatography. Results The total 24 hours urinary 8-OHdG excretion and the serum MDA concentration were higher than the normal values. The serum and urine SOD concentrations were lower than the normal values. There was an improvement in urinary 8-OHdG,serum and urine SOD, serum and urine MDA levels with losartan therapy. Compared with losartan 50 mg/d, the antioxidative effect of losartan 100 mg/d was more noticeable. Obvious decrease in 24-hour proteinuria on exposure to losartan was found, without severe adverse effect. Conclusions Oxidative stress damage is active in DN patients. Losartan has antioxidative effect on DN patients. Compared with losartan 50 mg/d, the antioxidative effect of losartan 100 mg/d is more marked, without increasing side effect. Losartan's antioxidative effect may be involved in its beneficial mechanisms on DN.

BACKGROUND:Previous studies have applied long-bone mechanical separation method to obtain osteoclasts, which are terminal y differentiated cells and cannot further proliferate. Therefore a large number of osteoclasts can be harvested with bone marrow cells inducing culture method and RAW264.7 cells inducing culture method to meet clinical requirements.
OBJECTIVE:To investigate the optimal method of receptor activator of nuclear factor kappa-B ligand (RANKL) induced osteoclast precursors to differentiate into mature osteoclasts.
METHODS:After bone marrow cells were isolated from mouse, RANKL and macrophage colony stimulating factor were added into the medium together, or RAW264.7 cells were cultured with RANKL to induce osteoclasts. The osteoclast precursors were treated with different concentrations of RANKL to observe the number of generated osteoclasts and evaluate the dose-effect relationship between RANKL and osteoclastogenesis. Annexin V-FITC and propidium iodide staining were used for flow cytometry to analyze the mononuclear-macrophage apoptosis during osteoclastogenesis.
RESULTS AND CONCLUSION:When 10μg/L RANKL was used, the peak of osteoclastogenesis appeared at days 6-7;when the concentration of RANKL was up to 100μg/L, the peak appeared at days 4-5. The number of new osteoclasts was dose-dependent on the RANKL concentration. 50μg/L of RANKL was the turning point in the fitted curve from osteoclastogenesis and RANKL concentration. After the RANKL concentration was more than 150μg/L, the number of osteoclasts slowed down obviously. RANKL can induce monocyte-macrophage to form osteoclasts and promote monocyte-macrophage apoptosis. The highest number of osteoclasts would be obtained to each unit of RANKL when monocyte-macrophage cells were cultured with 30μg/L of RANKL in the same vaccination density (104/cm2). Experimental findings indicate that, RAW264.7 cells or bone marrow cells inducing culture methods are simple and feasible, the optimum cellseeding density was 104/cm2;the appropriate stimulation concentration of RANKL was 30-50μg/L.
