Research progress on the pharmacological effects and mechanisms of sanggenon C / 中国药房

Sanggenon C is a kind of flavonoid compound mainly extracted from the traditional Chinese medicine Morus alba. The pharmacological effects and mechanisms of sanggenon C are systematically reviewed and summarized， and it is found that this component can improve pulmonary fibrosis by regulating transforming growth factor-β1 and nuclear factor-κB； it can exert anti- tumor effects by inhibiting the proliferation of tumor cells and inducing the apoptosis of tumor cells； it can exert cardioprotective， neuroprotective and hepatoprotective effects by regulating multiple signaling pathways， such as calcineurin/nuclear factor of activated T cells 2， peroxisome proliferators-activated receptor α， and Ras homolog gene family member A/Rho-associated coiled- coil containing protein kinase， enhancing autophagy， reducing inflammatory response and reducing the level of oxidative stress； it can treat osteoporosis by inhibiting osteoclast uptake and promoting osteoblast formation； it has certain inhibitory effect on many enzymes； it can exert anti-inflammatory effects by regulating nuclear factor-κB signaling pathway； it can exert antioxidant effects by scavenging free radicals. However， researches on the pharmacological effects of sanggenon C mostly focus on the cellular and animal field， and the specific mechanism of action is not yet clear. In the future， basic research and clinical trials are still needed to explore and verify.

Mesenchymal stem cells and immune disorders: from basic science to clinical transition / 医学前沿

As a promising candidate seed cell type in regenerative medicine, mesenchymal stem cells (MSCs) have attracted considerable attention. The unique capacity of MSCs to exert a regulatory effect on immunity in an autologous/allergenic manner makes them an attractive therapeutic cell type for immune disorders. In this review, we discussed the current knowledge of and advances in MSCs, including its basic biological properties, i.e., multilineage differentiation, secretome, and immunomodulation. Specifically, on the basis of our previous work, we proposed three new concepts of MSCs, i.e., "subtotipotent stem cell" hypothesis, MSC system, and "Yin and Yang" balance of MSC regulation, which may bring new insights into our understanding of MSCs. Furthermore, we analyzed data from the Clinical Trials database ( http://clinicaltrials.gov ) on registered clinical trials using MSCs to treat a variety of immune diseases, such as graft-versus-host disease, systemic lupus erythematosus, and multiple sclerosis. In addition, we highlighted MSC clinical trials in China and discussed the challenges and future directions in the field of MSC clinical application.

The meta-analysis on the correlation between depression and interleukin-6 / 中国神经精神疾病杂志

Objective To investigate the association of interleukin-6 (IL-6) with depression using meta analysis. Methods A systematic literature search was conducted to examine depression and interleukin-6 in Chinese patients us-ing“depression”and“interleukin-6”in Databases including PubMed, CBM, VIP, CNKI and WanFang Data. A me-ta-analysis was performed to analyze correlation between depression and interleukin-6 using RevMan 5.2.8 software. Results A total of 9 studies were recruited, involving 432 depression patients and 277 healthy controls. The results of meta-analysis showed that concentration of IL-6 was higher in depression patients than in healthy controls(SMD=1.48, 95%CI:0.78~2.18,P<0.05). Subgroup analysis in the first-episode subgroup and the non first-episode subgroup showed that concentration of interleukin-6 was higher in depression patients than that in controls [the first-episode subgroup (SMD=1.94,95%CI:0.07~3.81,P<0.05), the non first-episode subgroup (SMD=1.26,95%CI:0.60~1.93,P<0.05)]. Conclusion There is a good correlation between depression and the serum IL-6 concentration. Due to the small number of studies and heterogeneity in different studies, the present meta-analysis has not yet confirmed the quantitative correla-tion between IL-6 and depression.

Management of cerebral ischemia due to Takayasu's arteritis / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To explore the management of cerebral ischemia caused by Takayasu's arteritis.</p><p><b>METHODS</b>Ninety-three cases treated from June 1984 to September 1999 at the General Post & Telecom Hospital, the Sir Run Run Shaw Hospital, the First Affiliated Hospital of Zhejiang University, the Second Medical College of Beijing University, Beijing An Zhen Hospital, and the Beijing Union Medical College Hospital, including 10 men and 83 women, were reviewed. Of the 93 cases, bypasses from the ascending aorta to the axillary or subclavian artery and from graft to the carotid artery were performed in 47 cases. Subclavian to carotid bypass was performed in six cases. Percutaneous transluminal angioplasty (PTA) was used in five cases and stenting in one.</p><p><b>RESULTS</b>Marked improvement was achieved in 30.3%, fair in 34.9%, improvement in 21.2%, unchanged in 4.6%, and death in 9.0% before discharge; 30.6%, 38.8%, 16.3%, 4.1%, and 2.0% respectively during a mean follow-up of 48 months, and recurrence requiring revision in 8.2%.</p><p><b>CONCLUSION</b>Patients with occlusive lesions of all four cervical arteries always have severe cerebral ischemia and their distal runoff is always unvisualised by angiography. However, we found by exploration that the internal carotid artery is patent in all but one patient. Therefore, an ascending aorta to carotid bypass is feasible in most instances, and this can and should be done when the cerebral perfusion is jeopardized at a time when the patient is in a stable or relatively stable condition. Unfortunately, the cerebral re-perfusion syndrome is still a serious and not completely solved problem.</p>
