Chinese Medicine Involving Triple Rehabilitation Therapy for Knee Osteoarthritis in 696 Outpatients: A Multi-Center, Randomized Controlled Trial.

Objective: To determine the effects of Chinese medicine (CM) involving triple rehabilitation therapy on the progression of knee osteoarthritis (KOA).

Methods: A total of 722 patients recruited from 38 community health service centers located in China from March 2013 to March 2017 were randomly divided into treatment and control groups equally, using a cluster randomization design. Health education combined with CM involving triple rehabilitation therapy for KOA (electro-acupuncture, Chinese medicinal herb fumigating-washing, and traditional exercises) was administered in the treatment group while conventional rehabilitation therapy (physical factor therapy, joint movement training, and muscle strength training) was administered in the control group.

[Effect of naringin of Drynaria Rhizome, a Chinese medical component of Zhuanggu Jianxi Recipe containing serum on caveolin-p38MAPK signal pathway in IL-1β induced rabbit degenerated chondrocytes].

Objective: To observe the effect of naringin of Drynaria Rhizome, a Chinese medical component of Zhuanggu Jianxi Recipe (ZJR) containing serum on caveolin-p38MAPK signal factors (such as caveolin-1, p-p38, p-ATF-2, IL-1β, and TNF-α) in IL-1β induced rabbit degenerated chondrocytes, and further to explore its mechanism for protecting articular cartilages.

Methods: Naringin of Drynaria Rhizome was obtained and analyzed by HPLC-TOF/MS. Four weeks old New Zealand rabbits were killed and their bilateral knee joints were isolated aseptically.

[In vitro culture and identification of IL-1beta induced degeneration of cartilage cells in New Zealand white rabbits knee joint].

Objective: To explore and identify the method for IL-1beta induced New Zealand rabbit knee chondrocyte degeneration, thus providing experimental bases for Chinese medical research on osteoarthritis from in vitro cultured chondrocytes.

Methods: Under aseptic conditions, bilateral knee joint cartilage was collected from 4-week old New Zealand rabbits. Chondrocytes were separated by type II collagenase digestion and mechanical blowing method.

Zhuanggu Jianxi Decoction () limits interleukin-1 β-induced degeneration chondrocytes via the caveolin-p38 MAPK signal pathway.

Objective: To evaluate the effect of Zhuanggu Jianxi Decoction (, ZGJXD) on interleukin-1 β (IL-1 β)-induced degeneration of chondrocytes (CDs) as well as the activation of caveolin-p38 mitogen-activated protein kinase (MAPK) signal pathway, investigating the possible molecular mechanism that ZGJXD treats osteoarthritis.

Methods: Serum pharmacology was applied in the present study, where ZGJXD was orally administrated to New Zealand rabbits and then ZGJXD containing serum (ZGJXD-S) was collected for following in vitro experiments. CDs were isolated aseptically from New Zealand rabbits and then cultured in vitro.

[Experimental study on the effects of inactivated and un-inactivated pharmaco-serum of diabetic rats fed with Chinese herbs Qianggubao decoction on the proliferation of osteoblast cultured in vitro].

Objective: To study the effect of inactivated and un-inactivated pharmaco-serum of diabetic rats fed with Chinese herbs Qianggubao decoction on the proliferation of osteoblast cells (OB)cultured in vitro.

Methods: OB was isolated from the skull of newly born SD rats aged 1 to 2 days by means of Trypsin-collagenase digestion and identified by image analysis under inverted microscope, V-G collagen staining, ALP staining, calcification nod staining etc. After the OB was identified, in activated and un-inactivated pharmaco-serum of diabetic rats fed with Qianggubao decoction of ferent phase (rats were fed with medicine 3 days or 5 days after last fed with medicine 1 hour or 3 hours) and concentration (5%, 10%, 20%) were added to the OB and incubated.

[Experimental study on the effects of pharmaco-serum of diabetic rats fed with Chinese herbs qianggubao decoction ([Chinese characters: see text]) on osteoblast culture in vitro].

Objective: To investigate the optimum phase and dose of pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) on the differentiation and mineralization of osteoblast (OB). METHODS (OB) was isolated from the skull of 10 newly born SD rats aged 1 to 2 days by means of Trypsin-collagenase digestion. After the OB was identified, different kinds of pharmaco-serum of diabetic rats fed with inactive Qianggubao decoction ([Chinese characters: see text]) of different phase (rats were fed with medicine three days or five days after last fed with medicine one hour or three hours) and concentration (5%, 10%, 20%) were added to the OB and incubated.
