Exploring the "gene-metabolite" network of ischemic stroke with blood stasis and toxin syndrome by integrated transcriptomics and metabolomics strategy.

A research model combining a disease and syndrome can provide new ideas for the treatment of ischemic stroke. In the field of traditional Chinese medicine, blood stasis and toxin (BST) syndrome is considered an important syndrome seen in patients with ischemic stroke (IS). However, the biological basis of IS-BST syndrome is currently not well understood. Therefore, this study aimed to explore the biological mechanism of IS-BST syndrome. This study is divided into two parts: (1) establishment of an animal model of ischemic stroke disease and an animal model of BST syndrome in ischemic stroke; (2) use of omics methods to identify differentially expressed genes and metabolites in the models. We used middle cerebral artery occlusion (MCAO) surgery to establish the disease model, and utilized carrageenan combined with active dry yeast and MCAO surgery to construct the IS-BST syndrome model. Next, we used transcriptomics and metabolomics methods to explore the differential genes and metabolites in the disease model and IS-BST syndrome model. It is found that the IS-BST syndrome model exhibited more prominent characteristics of IS disease and syndrome features. Both the disease model and the IS-BST syndrome model share some common biological processes, such as thrombus formation, inflammatory response, purine metabolism, sphingolipid metabolism, and so on. Results of the "gene-metabolite" network revealed that the IS-BST syndrome model exhibited more pronounced features of complement-coagulation cascade reactions and amino acid metabolism disorders. Additionally, the "F2 (thrombin)-NMDAR/glutamate" pathway was coupled with the formation process of the blood stasis and toxin syndrome. This study reveals the intricate mechanism of IS-BST syndrome, offering a successful model for investigating the combination of disease and syndrome.

Clinical report on 5 cases of advanced malignancies with blood stasis and toxin treated by collateral disease theory.

BACKGROUND: "Collateral disease theory", as an important theory of traditional Chinese medicine, is often used in the clinical treatment of tumors, showing a remarkable effect, especially in advanced malignancies with blood stasis and toxin. METHODS: In this study, we analyzed 5 cases of advanced malignancies, and discussed the efficacy of collateral disease theory in advanced malignancies with blood stasis and toxin. The 5 cases were suffered from right lung squamous cell carcinoma, left lung squamous cell carcinoma, stage IV endometrial carcinoma, right submandibular lymphatic follicular lymphoma and right lower lung cancer, respectively. Combining with the pathogenesis of collateral disease in traditional Chinese medicine dialectically and taking insect medicine as an example, traditional Chinese medicine was prescribed. Furthermore, the application effect of "collateral disease theory" in malignancy with blood stasis and toxin was explored. RESULTS: After treated with traditional Chinese medicine, the tumor lesions in the 5 cases were reduced to varying degrees. CONCLUSION: The treatment based on "collateral disease theory" is effective for advanced malignancy with blood stasis and toxin, but this finding needs to be verified by prospective studies.

Clinical Efficacy of Dahuang Zhuyu Decoction for Oral Administration and Enema on Severe Acute Pancreatitis with Syndromes of Blood Stasis, Toxin and Its Effect on Serum Inflammatory Factors / 中国实验方剂学杂志

Objective::To observe the clinical efficacy of Dahuang Zhuyu decoction for oral administration and enema on severe acute pancreatitis with syndromes of blood stasis and toxin and its effect on serum inflammatory factors. Method::Sixty eight patients with severe acute pancreatitis with syndromes of blood stasis and toxin who were admitted in Henan Provincial People's Hospital from September 2017 to December 2018 were randomly divided into treatment group (34 cases) and control group (34 cases). The control group was treated with western medicine. The treatment group was treated with Dahuang Zhuyu decoction for oral administattion and enema in addition to the therapy of the control group. Both groups were treated for 7 days. Before and after treatment, abdominal pain, bloating, nausea and vomiting were scored separately, serum amylase (AMS), lipase (LPS), interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) were detected, and abdominal pain disappearance time, bloating disappearance time and exhaust recovery time were recorded. Result::After treatment, the abdominal pain score, abdominal distension score, nausea and vomiting score, serum AMS, LPS, IL-6 and TNF-α were lower than those before treatment (P<0.05), and those in treatment group was lower than those in control group (P<0.05). After treatment, IL-10 level in both groups was higher than those before treatment (P<0.05), and that in treatment group was higher than that in control group (P<0.05). The disappearance time of abdominal pain, the disappearance time of abdominal distension and the recovery time of exhaust were shorter in treatment group than in control group (P<0.05). The total effective rate of the treatment group was higher than that of the control group (P<0.05). Conclusion::Dahuang Zhuyu decoction for oral administration and enema for severe acute pancreatitis with syndromes of blood stasis and toxin can alleviate clinical symptoms, reduce amylase and lipase levels, inhibit the expression of pro-inflammatory factors, promote the expression of anti-inflammatory factors, restore intestinal function, and improve clinical efficacy.

Professor SHAN Zhaowei's Four Methods in the Differentiation and Treatment of Chronic Atrophic Gastritis / 浙江中医药大学学报

[Objective]To explore the clinical experience of professor SHAN Zhaowei treatment of chronic atrophic gastritis(CAG). [Method] To analyze SHAN Zhaowei professor from the perspective of four different pathogenesis of syndrome differentiation of CAG. To sum up professor SHAN Zhaowei 's clinical experience in the treatment of chronic atrophic gastritis, inheritance of Meng He YiPai essence. [Result] Professor SHAN Zhaowei treats CAG in qi, deficiency, blood stasis and toxin from four different pathogenesis to syndrome differentiation of traditional Chinese medicine treatment of CAG, mediation or insufficiency of qi activity, health, and remove stasis coating, detoxification cancer, the first emphasis on TCM four diagnosis, tongue mirror each other, differentiation is exquisite, precision, protecting stomach qi, along with the differentiation to add and subtract, insipid, but with magic effect. [Conclusion] The unique pathogenesis differentiation method in the treatment of CAG and the clinical experience for CAG of Professor SHAN Zhaowei is worth learning and promotion.
