OBJECTIVETo investigate the effect of Ermiao Recipe (, EMR) with medicinal guide Angelicae Pubescentis Radix (APR) on the homing of bone marrow stem cells (BMSCs) to focal zone in osteoarthritis (OA) rats.

METHODSForty-eight Sprague-Dawley rats were randomly assigned to the sham-operated, model, EMR, and EMR plus APR groups (12 rats in each group). The OA rat model was induced by anterior cruciate ligament transection and medial meniscus resection. All rats were injected with recombinant human granulocyte colonystimulating factor [rhG-CSF, 30 μg/(kg·d) for continuous 7 days], and rats in the EMR and EMR plus APR groups were treated with EMR or EMR plus APR at 1.6 or 1.9 g/(kg·d) for 3 or 6 weeks, respectively. Cartilage histopathologic changes were observed by hematoxylin and eosin staining. Chondrocytes apoptosis and cartilage matrix components were tested by transferase-mediated deoxyuridine triphosphate-biotin nick end labeling assay and special staining. Interleukin-1β (IL-1 β), tumor necrosis factor α (TNF-α), bone morphogenetic protein 2 (BMP-2), and transforming growth factor beta-1 (TGF-β1) in serum were detected by enzyme-linked immunosorbent assay or radioimmunoassay assay. Matrix metalloproteinase (MMP)-13, tissue inhibitors of metalloproteinase (TIMP)-1, bromodeoxyuridine (BrdU), cluster of differentiation 34 (CD34), and stromal cell derived factor 1 (SDF-1) were measured by immunohistochemistry assay.

RESULTSEMR and EMR plus APR significantly inhibited articular cartilage damage and synovium inflammation in OA rats at 3 or 6 weeks of treatment, the most obvious changes in these parameters were found in the EMR plus APR group. At 6 weeks, compared with EMR treatment, EMR plus APR remarkably inhibited chondrocytes apoptosis and the release of IL-1β and TNF-α, obviously decreased MMP-13 expression, and significantly increased expressions of proteoglycan, collagen, type II collagen and TIMP-1, serum levels of BMP-2 and TGF-β1 as well as expressions of BrdU, CD34 and SDF-1 in cartilage articular (P<0.01 or P<0.05).

CONCLUSIONThe medicinal guide APR improved the therapeutic effects of EMR on OA rats by promoting directional homing of BMSCs to focal zone.

This paper collected the traditional Chinese medicine (TCM) prescriptions of osteoporosis and osteoarthritis from CNKI to set up database and used TCM inheritance system to analyze the composing principles in prescriptions. We collected 103 and 106 prescriptions for osteoporosis and osteoarthritis respectively, then analyzed inherent principles between herbs in prescriptions by using the TCM inheritance system, and obtained the frequency of each herb, and drug combinations of two diseases' prescriptions. The result showed that the principles in TCM prescriptions of osteoporosis and osteoarthritis are similarities, buch as tonifying kidney and invigorating the circulation of blood, but differences of the specific drugs. That is to say, tonifying kidney is the main method of osteoporosis treatment, however, invigorating the circulation of blood is the main method of osteoarthritis treatment.

Thirty-one dogs with patellar luxation (grades 2 and 3) were categorized into three groups. Group 1 (G.1; n = 12) had sodium hyaluronate (SHA) intra-articularly injected into the stifle joint that received surgery. Group 2 (G.2; n = 10) received SHA twice: first after surgery and then 1 week later. Group 3 (G.3; n = 9) served as a control, without injection. Blood was collected before injection and then once a week for 4 weeks after injection for evaluation of chondroitin sulfate (CS-WF6) and hyaluronan (HA). The results revealed significantly (p < 0.05) improved clinical scores by the end of week 4 in G.1 and G.2 relative to G.3; however, there was no significant difference between G.1 and G.2. There was a significant decrease (p < 0.05) in serum CS-WF6 levels beginning at week 2 in G.1 and G.2. At weeks 3 and 4, serum HA in G.1 and G.2 differed from that in G.3 (p < 0.05). No significant difference (p > 0.05) was observed in serum biomarkers between G.1 and G.2. In conclusion, intra-articular injection with SHA after joint surgery may improve homeostasis of the joint, retarding the process of OA.

OBJECTIVETo observe the metabolic, regulatory and anti-oxidative effects of modified Bushen Huoxue Decoction (BSHXD), a Chinese herbal medicine for kidney (Shen)-reinforcement and blood-activation, on an osteoarthritis (OA) rabbit model.

METHODSA rabbit model for knee joint OA was established by the classic Hulth's method. The OA model rabbits were randomized into 5 groups: the model control group, the positive control group treated with glucosamine sulfate, and the three BSHXD treated groups treated respectively with low, moderate, and high doses of BSHXD. In addition, a normal control group and a sham-operated group were set up. Experimental animals were sacrificed after a 7-week treatment, and pathological changes in cartilaginous tissue were estimated using the Mankin criteria. Hydroxyproline (Hyp) and malonaldehyde (MDA) contents in blood serum and urine, as well as superoxide dismutase (SOD) activity and nitric oxide (NO) content in blood serum and knee joint synovial homogenates were detected.

RESULTSMankin scoring showed insignificant statistical differences between the various treatment groups (P >0.05), but all were better than the model control group (P <0.05). Serum and urinary contents of Hyp and MDA as well as serum and synovial levels of NO were significantly lower, but the SOD activity in blood serum and synovial tissue was higher in the BSHXD treated groups than in the model group P <0.01); the effect of BSHXD was dose-dependent to some extent.

CONCLUSIONThe modified BSHXD shows an effect of improving cartilage metabolism in experimental rabbits with OA, and possesses osteo-chondric protective effects in antagonizing peroxidation injury.

OBJECTIVETo observe the therapeutic effect of parthenolide (PTL) on rabbit knee arthritis (KOA) and its effects on serum expression of interleukin-1beta (IL-1beta) and contents of tumor necrosis factor-alpha (TNF-alpha).

METHODSEight rabbits were randomly selected from 40 healthy pure-bred New Zealand rabbits as the normal control group. The KOA model was established in the rest 32 rabbits by plaster cast fixation of the right hind limb extension position. After modeling they were randomly divided into 4 groups, i.e., the model control group, the high dose PTL group, the middle dose PTL group, and the low dose PTL group, 8 in each group. Serum contents of IL-1beta and TNF-alpha were detected using enzyme-linked immunosorbent assay.

RESULTSCompared with the model group, IL-1beta and TNF-alpha concentration decreased in the 3 PTL groups (P < 0.01). The decrement was positively correlated with PTL concentrations (IL-1beta: r = 0.55, P < 0.01; TNF-alpha: r = 0.56, P < 0.01). The inhibition reached the peak when the PTL concentration arrived at 20 micromol/L.

CONCLUSIONSPTL could down-regulate the blood IL-1beta and TNF-alpha concentrations of KOA rabbits. Besides, the decrement was positively correlated with the PTL concentration.

BACKGROUND: Estrogens act on estrogen receptors distributed in articular cartilages, synovial membrane, and ligaments, which are thought to be related with degenerative changes. Meanwhile, progesterone is known to have a weak anabolic action on bone formation This study evaluates the effects of estrogen and progesterone hormone on bone/cartilage turnover in ovariectomized (OVX) rats. METHODS: Thirty-five 7-month-old female Sprague-Dawley rats were randomly divided into 5 groups and then ovariectomized bilaterally except the sham control group. The first and the second group acting as controls did not receive hormonal therapy, the third group received estrogen, the fourth group received progesterone, and the fifth group received combination of both hormones 10 weeks after surgery. Evaluations were done using the serum levels of cartilage oligomeric matrix protein (COMP) for cartilage turnover, collagen type I C-telopeptide (CTX-1) and osteocalcin (OC) for bone turnover at 11, 15, 19 weeks after OVX and histology using the Osteoarthritis Research Society International (OARSI) osteoarthritis (OA) cartilage histopathology assessment system. RESULTS: Significantly less cartilage degradation (decreased levels of COMP) was found in the combined hormone treated group in comparison with OVX group. Similarly, both hormonal treatment resulted in increased bone formation and decreased bone resorption i.e., a low overall bone turnover status (decrease in the serum OC and CTX-1 levels). CONCLUSIONS: Combined estrogen and progesterone therapy was found to be convincing in terms of reducing the severity of OA in this experimental model.

OBJECTIVETo observe the therapeutic efficacy of Qianggu Granule (QGG), Diacerein Capsule (DC), and QGG + DC in treating knee osteoarthritis (KOA, belonging to Gan-Shen insufficiency induced vein stasis syndrome), and to explore the clinical advantages of QGG + DC.

METHODSNinety patients in line with the diagnosis standard were randomly assigned to three groups, i. e., the QGG group (30 case, treated by QGG), the Western medicine treatment group (30 case, treated by DC), and the combination therapy group (30 case, treated by QGG +DC). Then the patients' symptoms and signs were scored. Meanwhile, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), tumor necrosis factor alpha (TNF-alpha), comprehensive efficacy, and adverse reactions, etc. were assessed.

RESULTSThe ache could be obviously alleviated, the patients' joint function could be improved, and their quality of daily activities could be elevated in all the 3 groups. There was statistical difference in the symptoms and signs scores, CRP, ESR, and TNF-alpha before and after treatment (P < 0.05). Better effects were obtained in the combination therapy group (P < 0.05). As for the comprehensive efficacy, it was better in the QGG + DC group than in the QGG group and the DC group, showing statistical difference (P < 0.01).

CONCLUSIONSThe comprehensive therapeutic efficacy of applying QGG + DC in treating KOA (belonging to Gan-Shen insufficiency induced vein stasis syndrome) was superior to using QGG or DC alone. Besides, no obvious adverse reaction occurred.

OBJECTIVETo prove the clinical effect and mechanism of Bushen Huoxue Qubi Decoction on treatment of knee-osteoarthritis.

METHODNinty-six knee-osteoarthritic patients accompanied with symptoms of liver and kidney deficiency and blocked main and collateral channels were divided into two groups randomly. Patients in the treatment group (n = 48) were administrated by Bushen Huoxue Qubi Decoction one bag/day for four weeks; and those in the control group (n = 48) were given diacerein (50 mg Bid, Po) and celecoxib (0.2 Qd, Po) for four weeks. The changes of VAS score, Womac score, relative viscosity, aggregation index and IL-1beta, NO, iNOS, LPO, SOD in serum were observed. Adverse effects were determined during follow-up visit and detection for blood routine and hepatic and renal functions.

RESULTIts clinical control rates as per Western medicine and TCM standards for treatment of knee-osteoarthritis and effective rate were 33.3%, 37.5% and 97.9% respectively, which was remarkably higher than those in the control group (18.8%, 20.8% and 95.5%). Their difference showed statistical significance, P<0.05 or 0.01. Bushen Huoxue Qubi Decoction had an effect in obviously improving hemarheological index in 42 days and inhibiting IL-1beta, NO, iNOS and LPO better than the control group, by the contrast of 58.6% vs 47.3%, 50.1% vs 36%, 55.1% vs 41.9% and 46.7% vs 20.6% (P<0.05 or P<0.01). The treatment group also displayed a higher SOD capability the control group (2 514.71 +/- 812.65) vs (2 013.41 +/- 781.3), (P<0.01). Both groups reported no adverse effect.

CONCLUSIONBushen Huoxue Qubi Decoction has a better efficacy on knee-OA than traditional treatment methods (diacereinand + celecoxib) and showed no adverse effect.

This study was conducted to determine if nasal salmon calcitonin has additional beneficial effects on clinical symptoms, serum NO, IL-1beta, matrix metalloproteinase 3, urinary C-terminal telopeptide type II collagen (CTX-II) levels and MRI findings in knee osteoarthritis (OA) when used concomitantly with exercise therapy. Fifty female patients with knee OA were randomized into two groups. The first group (n = 30) received 200 IU/day nasal salmon calcitonin and a home exercise program; the second group (n = 20) received a home exercise program for 6 months. Compared with baseline,while significant improvements were observed in visual analogue scale (VAS), WOMAC pain, physical function scores, 20-m walking time (P < 0.001) and WOMAC stiffness score (P = 0.041) in the first group, walking and resting VAS, and WOMAC physical function scores were improved (P = 0.029) in the second group after treatment. Significantly increased levels of serum NO and urinary CTX-II (P < 0.001) and significant improvements in the area of medial femoral condyle (P < 0.05) were noted only in the first group. There were significant differences in VAS activation values (P = 0.032) and NO levels (P < 0.001) in the favor of the first group. In conclusion, nasal salmon calcitonin may have possible chondroprotective effects besides its known effects on symptoms in patients with knee OA.
