Objective: To observe the effect of Tuina (Chinese therapeutic massage) on creatine kinase (CK), mitochondrial Ca2+ concentration, and ultrastructure of skeletal muscle in delayed onset muscle soreness (DOMS) model rats.Methods: A total of 130 healthy male Sprague-Dawley rats were randomly divided into a blank group, an exercise control group, a pre-exercise Tuina group, and a post-exercise Tuina group. According to the time points for sample collection, the exercise control group was divided into a 0 h exercise control group, a 24 h exercise control group, a 48 h exercise control group, and a 72 h exercise control group; the pre-exercise Tuina group was further divided into a 0 h pre-exercise Tuina group, a 24 h pre-exercise Tuina group, a 48 h pre-exercise Tuina group, and a 72 h pre-exercise Tuina group; and the post-exercise Tuina group was divided into a 0 h post-exercise Tuina group, a 24 h post-exercise Tuina group, a 48 h post-exercise Tuina group, and a 72 h post-exercise Tuina group. Rats in all groups except for the blank group received DOMS modeling. Professionals performed Nie-Pinching manipulation and finger Nian-Twisting manipulation on the lower limbs of the rats. The samples were collected at 0 h, 24 h, 48 h, or 72 h after exhaustive exercise for each pre-exercise Tuina group. The samples were collected at 0 h, 24 h, 48 h, or 72 h after Tuina for each post-exercise Tuina group. The changes in serum CK, skeletal muscle mitochondrial Ca2+ concentration, and Ca2+-adenosine triphosphatase (ATPase) were determined. The ultrastructure changes of skeletal muscles in each group were observed by a transmission electron microscope. Results: The electron microscope showed that compared with the exercise control group, the skeletal muscle structures of the pre-exercise Tuina group and the post-exercise Tuina group were significantly improved, and the overall performance of skeletal muscle in the pre-exercise Tuina group was more similar to that of the blank group. The level of serum CK in the pre-exercise Tuina group and the post-exercise Tuina group was significantly lower than that in the exercise control group (P<0.01). The Ca2+ concentration of skeletal muscle in the 24 h, 48 h, and 72 h pre-exercise Tuina groups was lower than that in the post-exercise Tuina group at the same time point (P<0.01). The Ca2+-ATPase concentration of skeletal muscle in the 24 h and 72 h pre-exercise Tuina groups was lower than that in the post-exercise Tuina group at the same time point (P<0.05).Conclusion: Tuina effectively prevents muscle damage caused by heavy exercise and long-term exercise, which may be related to the increase of skeletal muscle Ca2+-ATPase activity and mitochondrial Ca2+ transport.

Objective: To explore the expression of the A_2A adenosine receptor and the inflammatory cytokines interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) in human degenerative nucleus pulposus (NP) cells after they have been treated with a pulsed electromagnetic field (PEMF). Methods: Human degenerative NP cells were cultured in vitro and treated using an 0.8mT PEMF with a pulse frequency of 50Hz. The pulse width was 150μs and the exposure time was 30min, repeated 5 times at 12 hour intervals. The expression of the A_2A adenosine receptor in NP cells was determined using western blotting and reverse transcription polymerase chain reactions. The expression of the inflammatory cytokines IL-1β and TNF-α were detected using enzyme-linked immunosorbent assays (ELISA). The human degenerative NP cells were also treated with an antagonist and agonist of the A_2A adenosine receptor, and the expression of IL-1β and TNF-α were also determined using ELISA. Results: After the PEMF treatment the expression of the A_2A adenosine receptor increased significantly, while the expression of IL-1β and TNF-α decreased significantly. However, the A_2A adenosine receptor antagonist reversed the inhibitory effect of the PEMF on the expression of IL-1β and TNF-α, while the agonist played an opposite role. Conclusion A PEMF can significantly inhibit the expression of IL-1β and TNF-α in human degenerative NP cells, which could be related to up-regulation of the expression of the A_2A adenosine receptor in those cells.

Objective To investigate the effect of acupuncture on the morphology of the dry eye rabbit's cornea and the nuclear factor κB(NF-κB)signaling pathway of the corneal tissue to analyze the mechanism of acupuncture on dry eyes.Methods Twenty-four healthy New Zealand rabbits,without restriction on sex,were randomly divided into four groups,including a blank group,a model group,an acupuncture group,and a sham acupuncture group,with 6 in each group.Rabbits in the blank group were not treated;rabbits in the other three groups were treated with scopolamine hydro-bromide 2.0 mg·kg-1 by subcutaneous injection at 8:00,11:00,14:00 and 18:00 each day for 35 consecutive days un-til the end of the experiment.Rabbits in the sham acupuncture group were treated with sham acupuncture on the 22nd day after successful modeling by quickly pricking acupoints(Jingming BL1,Cuanzhu BL2,Sizhukong SJ23,Taiyang EX-HN5 and Tongziliao GB1)with a blunt acupuncture needle,once a day,for a total of 14 days.Rabbits in the acupuncture group were treated with acupuncture at the same acupoints as the sham acupuncture group after successful modeling.The corneal fluorescence staining was conducted on Days 0,21,28 and 35 after modeling.On Day 35,corneal confocal microscope ex-aminations were conducted.Then,the rabbits were sacrificed,the corneal morphological changes were observed by light microscope and transmission electron microscope,and the expression of corneal NF-κB protein was detected by Western blot.Results Compared with the model group,the score of rabbit corneal fluorescein staining in the acupuncture group and blank group decreased on the 28th and 35th days after modeling,and the differences were statistically significant(all P＜0.05).The results of the confocal microscope examination on Day 35 after modeling showed that,compared with other groups,there were a large number of globular immune cells and activated stromal cells with unclear boundaries and irregu-lar sizes in the stromal layer and inflammation in the area with irregular intercellular space in the model group and the sham acupuncture group.In the acupuncture group,the morphology of stromal layer cells improved,the cells were slightly acti-vated,and there were no obvious abnormalities in the corneal nerve morphology.On the 35th day after modeling,the re-sults of the light microscope showed that,the surface of the corneal tissue in the model group and the sham acupuncture group showed hyperkeratinized flat epithelial cells,lymphocyte infiltration,increased number of focal epithelial cell layers,and epithelial cell detachment.In the acupuncture group,there were 4-6 layers of epithelial cells in the corneal epitheli-um,and epithelial shedding decreased.In addition,the lymphocyte infiltration decreased compared with the model group.On the 35th day after modeling,the results of the transmission electron microscope showed that abnormal microvilli oc-curred and epithelial cells were absent in the corneal epithelial cells of rabbits in the model group and the sham acupuncture group,the cell space was widened,the rough endoplasmic reticulum was severely expanded,and desmosomes were dis-banded with mitochondrial swelling.In the acupuncture group,the microvilli structure of epithelial cells was sparse and short,local deletion was still observed,the rough endoplasmic reticulum was slightly expanded,and no obvious swelling of mitochondria was observed.On the 35th day after modeling,the Western blot examination results showed that,compared with the blank group,the expression of p-NF-κB p65 was up-regulated in both the model group and sham acupuncture group(both P＜0.05);compared with the model group and sham acupuncture group,the expression of p-NF-κB p65 in the acupuncture group was down-regulated(both P＜0.05).Conclusion Acupuncture can inhibit the NF-κB signaling path-way to play an anti-inflammatory role and relieve corneal inflammation and injury of dry eye rabbit models.
