Résumé
As the research of traditional Chinese medicine （TCM） on knee osteoarthritis （KOA） is progressing， researchers have discovered that a variety of Chinese medicines can delay the progress of KOA by regulating signaling pathways at the molecular level. The Chinese medicines and their active ingredients mentioned in this article are associated with the signaling pathways in KOA. They can regulate the levels of targeted molecules via different signaling pathways to inhibit cartilage inflammatory cytokine， apoptosis， and cartilage matrix degradation and promote chondrocyte autophagy， so as to reduce the synovial inflammatory edema and delay cartilage degeneration. This paper systematically reviews the studies about the TCM intervention of KOA. Baicalein can reduce the inflammatory cytokines and apoptosis and promote the autophagy of chondrocytes by blocking the phosphatidylinositol-3 kinase/protein kinase （PI3K/Akt） signaling pathway. Cornuside I can decrease the phosphorylation activity of Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3） pathway to reduce synovial inflammation and delay cartilage matrix degeneration. Salvianolic acid A can reduce inflammation and cartilage matrix degradation by inhibiting the phosphorylation of the nuclear factor-κB （NF-κB） pathway. Emodin can reduce the activity of Wnt/β-catenin pathway to inhibit the decomposition of collagen and proteoglycan. Myristicoside can inhibit apoptosis by blocking the p38 mitogen-activated protein kinase （p38 MAPK） signaling pathway. Akebia saponin D can enhance the activity of nuclear factor E2-related factor 2/heme oxygenase 1（Nrf2/HO-1） pathway to inhibit oxidative stress in chondrocytes. The saponins in Achyranthis Bidentatae Radix reduce cartilage matrix degradation by enhancing the transforming growth factor-β （TGF-β）/Smad signaling pathway. Crocin inhibits the cartilage inflammation and apoptosis factor increase by stimulating the activity of hippo-Yes-associated protein （Hippo-YAP）. Ligustrazine blocks the Notch pathway to improve the morphology and abnormality of chondrocytes. Oleanolic acid reduces the destruction and degeneration of cartilage matrix via the estrogen signaling pathway. The above summary aims to provide references for future clinical and experimental research on KOA.
Résumé
Objective To observe the clinical efficacy of thunder-fire moxibustion at Dazhui (GV14) and Shenshu (BL23) in treating mild cognitive impairment (MCI) due to ischemic cerebral stroke. Method Sixty patients with MCI due to ischemic cerebral stroke were randomized into a treatment group and a control group, 30 cases each. The control group was intervened by joint treatment plus cognitive training, while the treatment group was by thunder-fire moxibustion in addition to that given to the control group. The two groups were evaluated by the Montreal Cognitive Assessment (MoCA), Mini-Mental State Examination (MMSE) and Wechsler Memory Scale (WMS), the major symptoms were observed, and the clinical efficacies were compared between the two groups. The two groups were both treated for 8 weeks. Result The total effective rate was 80.0%in the treatment group, versus 70.0% in the control group, and the difference was statistically significant(P<0.05). Conclusion The selected acupoints can improve the cognition and activities of daily living (ADL) in MCI patients;thunder-fire moxibustion at Dazhui and Shenshu plus cognitive training can produce a better clinical efficacy than dry cognitive training. Therefore, we can combine thunder-fire moxibustion with modern rehabilitation to enhance the therapeutic efficacy in preventing and treating MCI.

Objective To investigate the clinical efficacy of Nazi method of midnight-midday ebb flow plus warm needling moxibustion in treating transient ischemic attack (TIA). Methods Sixty patients with transient ischemic attack were randomly allocated to treatment and control groups, 30 cases each. The control group received routine medication and the treatment group, Nazi method of midnight-midday ebb flow plus warm needling moxibustion in addition. The main clinical symptoms were observed by TCD monitoring of microembolic signals in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results After treatment, the positive rate of microembolus monitoring was 3.3%in the treatment group and 20.0%in the control group;there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the traditional Chinese medical syndrome score in the two groups (P<0.05). There was a statistically significant post-treatment difference in the traditional Chinese medical syndrome score between the treatment and control groups (P<0.05). The total efficacy rate was 96.7% in the treatment group and 80.0% in the control group;there was a statistically significant difference between the two groups (P<0.05). At six months after treatment, the rate of disappearance of TIA, the rate of recurrence of TIA and the rate of occurrence of cerebral infarction were 90.0%, 6.7%and 3.3%, respectively, in the treatment group and 60.0%, 20.0%and 20.0%, respectively, in the control group;there were statistically significant differences between the two groups (P<0.05). Conclusions Nazi method of midnight-midday ebb flow plus warm needling moxibustion can decrease the positive rate of microemboli and shorten transient ischemic attack to prevent cerebral infarction in patients with transient ischemic attack.

ObjectiveTo seek an effective method in treating urinary retention due to incomplete spinal cord injury.Method Forty patients were randomized into two groups. Twenty subjects in the treatment group were intervened by alignedneedling at Jiaji points (EX-B2) plus warm needling; the other 20 subjects in the control group were by aligned needling at Jiaji points (EX-B2) alone. ResultAfter intervention, urinary retention symptoms were improved in both groups (P<0.05), and the improvement in the treatment group was more significant than that in the control group (P<0.05); the totaleffective rate was 85.0% in the treatment group versus 55.0% in the control group, and the difference was statistically significant (P<0.05).ConclusionAligned needling at Jiajiplus warm needling can produce a more significant efficacy than aligned needling at Jiajialone in treating urinary retention after incomplete spinal cord injury.
Résumé
Objective To evaluate Janus kinase (JAKs) and Suppressors of cytokine signaling(SOCSs) expression in myocardium after endurance training. Methods 30 male Sprague-Dawley rats undertook 10 weeks grade treadmill training program and were sacrificed at 0 and 24 h respectively after the last exercise. JAK1,JAK2,JAK3 and SOCS1 ,SOCS2,SOCS6 expression in the myocardium were determined by im munohistochemistry method. Results The percentage of JAK1 positive cell significantly increased immediately after last running and recovered to the sedentary level 24 hrs after exercise;The percentage of JAK2 positive cell significantly increased immediately after last running and continuously at a higher level 24 hrs after exercise (P0.05). The percentage of SOCS1 and SOCS2 positive cell also significantly increased both immediately and 24 hrs after exercise (P0.05). Conclusion Endurance training could induce different responses of JAK1,JAK2 and JAK3. The increased expressions of JAK1 and JAK2 might indicate the changes of JAK/STAT signal pathway in regulating myocardial function. The increased expressions of SOCS1 and SOCS2 after endurance training might indicate the increased exertion in regulating JAK/STAT signal pathway in cardiac muscle.
