AIM To investigate the clinical effects of Jingu Xiaotong Powder combined with platelet-rich plasma on patients with knee osteoarthritis.METHODS Ninety-six patients were randomly assigned into control group(48 cases)for 8-week administration of platelet-rich plasma,and observation group(48 cases)for 8-week administration of both Jingu Xiaotong Powder and platelet-rich plasma.The changes in clinical effects,IL-17,SDF-1,TLR4,GSH-Px,NO,ox-LDL,WOMAC scores,TCM syndrome score,AIM2-SF score were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P<0.05).After the treatment,the two groups displayed decreased IL-17,SDF-1,TLR4,NO,ox-LDL,WOMAC scores,TCM syndrome score(P<0.05),and increased GSH-Px,AIM2-SF score(P<0.05),especially for the observation group(P<0.05).CONCLUSION For the patients with knee osteoarthritis,Jingu Xiaotong Powder combined with platelet-rich plasma can reduce IL-17,SDF-1,TLR4 levels,inhibit body inflammation,improve oxidative stress indices,alleviate pain,and enhance clinical efficacy and life quality.
摘要
Anxiety disorders are currently a major psychiatric and social problem, the mechanisms of which have been only partially elucidated. The hippocampus serves as a major target of stress mediators and is closely related to anxiety modulation. Yet so far, its complex anatomy has been a challenge for research on the mechanisms of anxiety regulation. Recent advances in imaging, virus tracking, and optogenetics/chemogenetics have permitted elucidation of the activity, connectivity, and function of specific cell types within the hippocampus and its connected brain regions, providing mechanistic insights into the elaborate organization of the hippocampal circuitry underlying anxiety. Studies of hippocampal neurotransmitter systems, including glutamatergic, GABAergic, cholinergic, dopaminergic, and serotonergic systems, have contributed to the interpretation of the underlying neural mechanisms of anxiety. Neuropeptides and neuroinflammatory factors are also involved in anxiety modulation. This review comprehensively summarizes the hippocampal mechanisms associated with anxiety modulation, based on molecular, cellular, and circuit properties, to provide tailored targets for future anxiety treatment.

Objective:To observe the clinical efficacy of modified Chushi Juanbitang combined with pedicle vertebrotomy on kyphosis of ankylosing spondylitis due to syndrome of dampness-heat obstruction. Method:The 90 cases were randomly divided into control group and observation group, 45 cases in each group. The patients in control group received pedicle vertebrotomy + <italic>Tripterygium</italic> glycosides, and the patients in observation group received pedicle vertebrotomy + modified Chushi Juanbitang. The treatment course was 6 months in both groups. Their bath ankylosing spondylitis disease activity index (BASDAI), bath ankylosing spondylitis measure index (BASMI), imaging index, traditional Chinese medicine syndromes, serum proinflammatory factor, anti-inflammatory factor, bone metabolism index [bone-specific alkaline phosphatase (BALP), tartrate resistant acid phosphatase isomer-5b (TRACP-5 b), bone morphogenetic protein-2 (BMP-2), osteocalcin (BGP)], ossification related proteins [bone morphogenetic protein-7 (BMP-7), dickkopf-related protein-1 (DKK-1), and tissue inhibitor matrix metalloproteinase-2 (TIMP-2), sclerostin(SOST)] were observed and detected. The clinical efficacy, recurrence rate and safety indexes were followed up for 12 months and compared. Result:The total effective rate was 97.73% (43/44) in the observation group, higher than 80.95% (34/42) in the control group (<italic>χ</italic><sup>2</sup>=5.172, <italic>P</italic><0.05). In the comparison with control group after treatment, the BASDAI, BASMI, imaging index, traditional Chinese medicine syndromes, proinflammatory factors, TRACP-5b, BMP-7 and TIMP-2 were lower in observation group (<italic>P</italic><0.05), and the anti-inflammatory factors, BALP, BMP-2, BGP, DKK-1 and SOST were higher in observation group (<italic>P</italic><0.05). During the follow-up for at least 12 months, the recurrence rate was 4.65% (2/43) in observation group, lower than 26.47% (9/34) in control group (<italic>χ</italic><sup>2</sup>=4.261, <italic>P</italic><0.05). There was no significant difference in the incidence of postoperative complications between the two groups. The incidence of adverse reactions was 2.27% (1/44) in observation group, lower than 38.64% (17/44) in control group (<italic>χ</italic><sup>2</sup>=5.763, <italic>P</italic><0.05). Conclusion:Modified Chushi Juanbitang combined with pedicle vertebrotomy is effective in the treatment of kyphosis of ankylosing spondylitis due to syndrome of dampness-heat obstruction.
摘要
The present study was aimed to examine if protein kinase C (PKC) activation is necessarily involved in both the c-fos protein expression in the nocuously-activated c-fos protein-like immunoreactive (Fos-LI) neurons and the concomitant opioid receptor-mediated modulation in the dorsal horn circuitry of the spinal cord. Formalin was injected into a hindpaw of rats 5 min after the rats were pretreated with intrathecal (i.t.) administration of chelerythrine (Chel), an inhibitor of PKC, naloxone (Nal), combined administration of these two (Chel + Nal), or vehicle (n=5 in each group),respectively. By using immunocytochemical techniques, the formalin-induced Fos-LI neurons in the lumbar dorsal horn were calculated 1 h after formalin injection. The results showed that: (1) i.t. Chel significantly reduced the number of Fos-LI neurons in the dorsal horn of the spinal cord on the side ipsilateral to the formalin injection, showing a decrease by 60.3% (P<0.001) as compared to that observed in the i.t.vehicle group; (2) i.t. Nal significantly increased the number of Fos-LI neurons in the ipsilateral dorsal horn, with an increase of 46.0% (P<0.01) as compared to that in the i.t.vehicle group, the highest percentage increase being found in the deeper laminae of the dorsal horn; and (3) i.t. Chel + Nal also exhibited a significant decrease in Fos-LI neurons in the ipsilateral dorsal horn as compared to i.t. Nal group, showing a reduction of 53.2%, a value similar to that in the i.t. Chel group. These results suggest that: (1) PKC plays a role in the c-fos protein expression only in nearly one half of the Fos-LI neurons in the dorsal horn; and (2) PKC is possibly not involved in the concomitant modulation on the nociception mediated by micro- (and also partly delta-) opioid receptors in the spinal cord.
