Expert consensus on Tongsaimai Tablets/Capsules in treatment of peripheral vascular diseases in clinical practice / 中国中药杂志

Tongsaimai Tablets/Capsules are composed of Lonicerae Japonicae Flos, Angelicae Sinensis Radix, Achyranthis Bidentatae Radix, Codonopsis Radix, Dendrobii Caulis, Astragali Radix, Scrophulariae Radix, and Glycyrrhizae Radix et Rhizoma, and are effective in promoting blood circulation, removing blood stasis, supplementing Qi, and nourishing Yin. It is widely used in the treatment of peripheral vascular diseases. With 40 years of clinical application, it has accumulated substantial research data and application experience. Its good clinical efficacy and pharmacoeconomic benefits in improving the clinical symptoms of peripheral vascular diseases have been confirmed by relevant research. Meanwhile, this drug has also been recommended by many expert consensus, guidelines, and teaching materials, serving as one of the most commonly used Chinese patent medicines in clinical practice. To further improve the understanding of the drug among clinicians and properly guide its clinical medication, the China Association of Chinese Medicine took the lead and organized experts to jointly formulate this expert consensus. Based on the questionnaire survey of clinicians and the systematic review of research literature on Tongsaimai Tablets/Capsules with clinical problems in the PICO framework, the consensus, combined with expert experience, concludes recommendations or consensus suggestions by GRADE system with the optimal evidence available through the nominal group technique. This consensus defines the indications, usage, dosage, course of treatment, medication time, combined medication, and precautions of Tongsaimai Tablets/Capsules in the treatment of peripheral vascular diseases, and explains the safety of its clinical application. It is recommended for clinicians and pharmacists in the peripheral vascular department(vascular surgery), traditional Chinese medicine surgery(general surgery), and endocrinology department of hospitals at all levels in China.

P38MAPK pathway regulates COX-2 and caspase-3 expression in a mouse model of Parkinson disease / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the effect of p38 mitogen-activated protein kinase (p38MAPK) on the expression of COX-2 and caspase-3 in the substania nigra (SN) of mice with MPTP-induced Parkinson disease (PD).</p><p><b>METHODS</b>C57BL/CN mice were treated with MPTP to prepare a subacute PD model, and their behavioral changes following the treatment were observed. Immunohistochemistry and Western blotting were performed to detect the expression of tyrosine hydroxylase (TH), COX-2 and phosphorylation of P38MAPK in the SN and their changes following treatment with SB203580, a specific inhibitor of P38MAPK.</p><p><b>RESULTS</b>The 7-day model group showed typical symptoms of PD with decrements of TH-positive neurons and TH protein level in the SN of the midbrain by about 65% and 75%, respectively (P<0.01). In the 3-day model group, the COX-2-, caspase-3- and phosphorylated P38MAPK-immunoreactive cells and their protein levels in the SN increased markedly with obvious loss of TH-positive neurons. Administration of SB203580 obviously lessened the above changes (P<0.01).</p><p><b>CONCLUSION</b>P38MAPK regulates the inflammation and apoptosis in the SN of the mouse model of subacute PD, and SB203580 may provide some neuroprotective effect.</p>
