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.

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.

Twenty-five dogs were included in a randomized, double-blind trial to assess the efficacy of doxycycline (DOX) orally administered twice a day at 4 mg/kg/day (n = 12) for the treatment of osteoarthritis of the hip. Chondroitin sulfate (CS; 525 mg/day) was used as a positive control (n = 13). Dogs were re-examined monthly for 6 months after initiation of treatment. The assessment protocol included clinical score, radiographic findings and serum osteoarthritis biomarkers. Dogs treated with DOX showed statistically significant improvements (p < 0.05) in lameness, joint mobility, pain on palpation, weight-bearing and overall score at 2, 6, 4, 4 and 4 months, respectively, after treatment. Biomarker levels of CS-WF6 epitope and hyaluronan were significantly increased and decreased (p < 0.05) at 2 and 3 months after treatment compared to pretreatment. These results showed that DOX had a positive therapeutic effect in dogs with osteoarthritis.

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 determine the levels of CC chemokine ligand 5 (CCL5) in serum and synovial fluid (SF) from patients with rheumatoid arthritis (RA) and their relations with disease activity and medication.

METHODSCCL5 in serum and SF was quantified by enzyme-linked immunosorbent assay (ELISA) in 28 RA patients and 21 osteoarthritis (OA) patients. In RA patients, the correlations of CCL5 levels in serum and SF with disease activity were analyzed. Meanwhile, the serum CCL5 levels among RA patients treated with disease-modifying antirheumatic drugs (DMARDs), Tripterygium Glucosides, and other Chinese herbs without disease-modifying effects were also compared.

RESULTSCCL5 levels in both serum and SF of RA patients were significantly higher than those of OA patients (P < 0.05). Moreover, the level of CCL5 was higher in SF than that in serum of RA patients (P < 0.01). Serum CCL5 level was correlated significantly with the number of swollen joints (r = 0.3329, P < 0.05), erythrocyte sedimentation rate (r = 0.4001, P < 0.05), and C reactive protein (r = 0.3735, P < 0.01). In addition, the level of CCL5 had a trend of lower in patients treated with DMARDs or Tripterygium Glucosides than those treated with other Chinese herbs, although the difference was not significant among those patients due to the small number of patients in each group.

CONCLUSIONSIn RA patients, the expression of CCL5 increases and correlates with some clinical and laboratory parameters of RA, which indicate that CCL5 plays an important role in RA and may serve as a useful marker of disease activity. DMARDs and Tripterygium Glucosides might exert their clinical effects through reducing CCL5 production in RA.

OBJECTIVETo investigate the mechanism of Tougu Xiaotong Granula (TXG) on prevention and treatment of knee osteoarthritis.

METHODSFifty New Zealand rabbits were randomly divided into 6 groups. Except those in the normal control group, all the rabbits were replicated into knee osteoarthritis model using modified Hulth method. They were administered by gastrogavage once every day respectively with 100 ml of normal saline to the rabbits in the normal group and those in the model group, with 10 g of Zhuanggu Guanjie Pill to those in the control group, and 5 g, 10 g and 20 g of TXG to those in the three TXG tested groups (tested group 1, 2 and 3). The levels of interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) and metalloproteinase 3 (MMP-3) in joint fluid, the blood content of malondialdehyde (MDA) and nitric oxide (NO) absorbance as well as the SOD activity in synovia were observed.

RESULTSOverexpressions of IL-1, IL-6, TNF-alpha and MMP-3 in joint fluid, increased blood content of NO and MDA were shown in the 8th and 16th week, and decreased SOD activity in synovia was shown in the 16th week of the experiment in all the model rabbits, as compared to those in the normal group, the difference was significant respectively (P < 0.05 or P<0.01). After 8 weeks of treatment, the levels of IL-1, TNF-alpha, MMP-3, NO and MDA in the control group, tested group 2 and 3 were significantly different to those in the model group respectively (P < 0.05, P < 0.01), and significant difference was also shown in the comparisons of those indexes between the control group and the tested group 1 vs the tested group 3 (P < 0.05). As for the level of IL-6, significant difference was shown in comparisons of the model group with the control group, tested group 2 and 3 in the 8th and 16th week of the treatment (P < 0.05 or P < 0.01), also in comparison of the tested group 3 with the tested group 1 in the 8th week, and in that of the tested group 2 with the control group and the tested group 1 in the 16th week (P < 0.05).

CONCLUSIONTXG could effectively postpone the degeneration of cartilage through effectively inhibiting the biological effects of cytokines, MMP-3 and oxygen free radical.

OBJECTIVETo observe the therapeutic efficacy and safety of Gubitong Recipe (, GBT) in treating osteoarthritis (OA) of knee joint.

METHODSNinety patients with knee osteoarthritis were equally assigned, according to a randomizing digital table, to the treatment group and the control group. The treatment group was treated with GBT Decoction one dose every day and the control group with glucosamine sulfate 500 mg thrice a day, respectively, for eight successive weeks. Besides, diclofenac sodium could be given as supplementary dugs with the dosage used recorded if necessary. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC, an index reflecting the degree of joint pain, stiffness, and dysfunction) in patients was assessed before and after treatment, and the patients' symptoms were evaluated by visual analogue scale (VAS) as well. Moreover, erythrocyte sedimentation rate (ESR), blood C-reactive protein (CRP), blood and urinary routine tests, liver and kidney function examination, and the adverse reaction that occurred during the treatment period were observed.

RESULTSWOMAC index and integral VAS value were lowered in both groups after treatment, showing significant statistical difference as compared with before treatment (P<0.05), but the decrement of WOMAC index in the treatment group was more significant than that in the control group (P<0.05). ESR and CRP levels remained unchanged in all patients, and the proportion and mean dosage of diclofenac sodium used were similar in the two groups. No evident adverse reaction occurred during the treatment period.

CONCLUSIONGBT is an effective and safe recipe for the treatment of osteoarthritis of knee joint, which could alleviate the joint pain, stiffness, and dysfunction.

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.

The interleukin-33 (IL-33)/ST2 pathway has emerged as an intercellular signaling system that participates in antigen-allergen response, autoimmunity and fibrosis. It has been suggested that IL-33/ST2 signaling has been involved in the pathogenesis of rheumatoid arthritis (RA), because IL-33 and its receptor have been specifically mapped to RA synovium. The aim of this study was to determine the levels of IL-33 and sST2 in sera and synovial fluids in patients with RA. The serum level of IL-33 was significantly higher in patients with RA (294.9 +/- 464.0 pg/mL) than in healthy controls (96.0 +/- 236.9 pg/mL, P = 0.002). The synovial fluid level of IL-33 was significantly higher in RA patients than in osteoarthritis patients. The level of serum sST2 was higher in RA patients than in healthy controls (P = 0.042). A significant relationship was found between the levels of IL-33 and IL-1beta (r = 0.311, P = 0.005), and IL-33 and IL-6 (r = 0.264, P = 0.017) in 81 RA patients. The levels of IL-33, sST2 and C-reactive protein decreased after conventional disease-modifying antirheumatic drugs treatment in 10 patients with treatment-naive RA. Conclusively, IL-33 is involved in the pathogenesis of RA and may reflect the degree of inflammation in patients with RA.
