Exploring Modern Mechanism of Treating Diabetic Retinopathy and Coronary Heart Disease from Perspective of Blood Stasis Under Viewpoint of Treating Different Diseases with the Same Method / 中国实验方剂学杂志

Diabetic retinopathy（DR） and coronary heart disease（CHD） are both major chronic vascular complications that seriously jeopardize the health of the population and often occur together in clinical practice， it is of great clinical value to actively explore the association between the two in the process of disease development and methods of prevention and treatment of modern medicine and traditional Chinese medicine（TCM）. According to TCM， the heart and eyes physiologically communicate with each other by taking Qi， blood and veins as bridges， blood stasis obstructing collaterals is the common TCM etiology of DR and CHD， whose mechanism involves inflammation， oxidative stress and endothelial dysfunction. Promoting blood circulation and removing blood stasis plays an important role in the same treatment for different diseases and prevention and treatment of comorbidities， possibly by inhibiting the expression of interleukin-1β（IL-1β）， endothelin-1（ET-1） and hypoxia inducible factor-1α/vascular endothelial growth factor（HIF-1α/VEGF）， regulating phosphatidylinositol 3-kinases/protein kinase B/mammalian target of rapamycin（PI3K/Akt/mTOR） pathway， initiating adenosine monophosphate（AMP）-activated protein kinase/silent information regulator 1（AMPK/SIRT1） and nuclear transcription factor erythroid 2-related factor 2/heme oxygenase-1（Nrf2/HO-1） signaling pathways， inhibiting Hippo/Yes-associated protein（Hippo/YAP） signaling pathway， inhibiting mitochondrial permeability transition pore and anti-platelet agglutination for treating DR and CHD， which provides a multi-component， multi-pathway and multi-target selection strategies and ideas for the prevention and treatment of DR and CHD by TCM from a biological perspective. Based on this， subsequent studies should focus on constructing clinically relevant comorbidity models， conducting multicenter prospective studies， and fully utilizing artificial intelligence technology to gain a deeper understanding of the relationship between the two diseases， so as to elucidate the mechanism of promoting blood circulation and removing blood stasis in preventing and treating panvascular diseases.

Comparison on Rat Models of Acute Cerebral Infarction Due to Stasis Combined with Toxin Complicated with Cerebral-cardiac Syndrome / 中国实验方剂学杂志

ObjectiveTo observe and compare the electrocardiogram index， myocardial morphology， and connexin 43 （Cx43） expression of two rat models of acute cerebral infarction （ACI） due to stasis combined with toxin complicated with cerebral-cardiac syndrome （CCS）， and to provide experimental evidence for the research on the occurrence mechanism of cardiac diseases induced by ACI and the clinical diagnosis and treatment of CCS. MethodSixty SPF-grade male SD rats were randomized into six groups （n=10）： normal ， syndrome of stasis combined with toxin induced by carrageenin combined with dry yeast （CA/Y）， multi-infarct induced by micro-embolism （ME）， middle cerebral artery occlusion （MCAO）， CA/Y+ME， and CA/Y+MCAO groups. The model of syndrome of stasis combined with toxin was established by intraperitoneal injection with carrageenan （CA） at 10 mg·kg-1 on the first day and subcutaneous injection with dry yeast （Y） suspension （2 mg·kg-1） on the second day of modeling. Twenty-four hours after the modeling of ACI， the electrocardiograms （ECGs） of rats in each group were collected and the number/percentage （%） of abnormal ECG was calculated. The infarct area of the brain was evaluated by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and myocardial injury was assessed by hematoxylin-eosin （HE） staining. Immumohistochemical staining and Western blot were employed to determine the expression of Cx43 in the myocardium. ResultA certain number of rats in each model group presented abnormal ECG. Compared with the normal group and CA/Y group， CA/Y+MCAO group had the highest rate of abnormal ECG （P<0.01）. Compared with the normal， CA/Y， ME， and CA/Y+ME groups， the CA/Y+ME and CA/Y+MCAO groups showed decreased amplitudes of P-wave and T-wave， shortened P-R interval， and extended Q-T interval， which were particularly obvious in the CA/Y+MCAO group （P<0.05， P<0.01） and in accordance with the cerebral infarction area and pathological changes. The expression of Cx43 was up-regulated in both CA/Y+ME and CA/Y+MCAO groups， especially in the CA/Y+MCAO group （P<0.01）. ConclusionThe two rat models of ACI due to stasis combined with toxin complicated with CCS can be used to study the mechanism of heart diseases caused by cerebrovascular diseases and the therapeutic effects of Chinese medicines with the functions of resolving stasis and detoxifying. Moreover， the CA/Y+MCAO method has higher abnormal electrocardiogram rate， severer myocardial pathological injury， and higher expression of Cx43 protein. The models can be chosen according to specific experimental purpose.

Dammarane-type triterpenoid saponins isolated from Gynostemma pentaphyllum ameliorate liver fibrosis via agonizing PP2Cα and inhibiting deposition of extracellular matrix / 中国天然药物

Gypenosides, structurally analogous to ginsenosides and derived from a sustainable source, are recognized as the principal active compounds found in Gynostemma pentaphyllum, a Chinese medicinal plant used in the treatment of the metabolic syndrome. By bioactive tracking isolation of the plants collected from different regions across China, we obtained four new gypenosides (1-4), together with nine known gypenosides (5-13), from the methanol extract of the plant. The structures of new gypenosides were elucidated by one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) spectra, complemented by chemical degradation experiments. Through comprehensive evaluation involving COL1A1 promoter assays and PP2Cα activity assays, we established a definitive structure-activity relationship for these dammarane-type triterpenoids, affirming the indispensability of the C-3 saccharide chain and C-17 lactone ring in effectively impeding extracellular matrix (ECM) deposition within hepatic stellate cells. Further in vivo study on the CCl4-induced liver damage mouse model corroborated that compound 5 significantly ameliorated the process of hepatic fibrosis by oral administration. These results underscore the potential of dammarane-type triterpenoids as prospective anti-fibrotic leads and highlight their prevalence as key molecular frameworks in the therapeutic intervention of chronic hepatic disorders.

Dietary Patterns for Prevention and Treatment of Cardiometabolic Disease： Interpretation and Thinking Based on Traditional Chinese Medicine Theory / 中国实验方剂学杂志

Cardiometabolic disease （CMD） is a clinical syndrome in which there is a causal relationship between metabolic abnormalities and cardiovascular damage. The incidence and mortality rates of CMD remain high despite the use of potent pharmacologic interventions and clinical therapeutic approaches. There is an urgent need for effective evidence-based comprehensive management measures to improve patients' lifespan and quality of life. From the concept of "nourishing through food" proposed in the Huangdi's Internal Classic （Huang Di Nei Jing） to the widespread application of modern dietary patterns such as dietary restriction， plant-based diets， and Jiangnan cuisine， dietary regulation plays a significant role in preventing diseases， early treatment of existing diseases， and recovery. This article systematically reviewed the traditional Chinese medicine （TCM） theory related to dietary patterns， elucidated the cutting-edge evidence and mechanisms of modern dietary patterns like dietary restriction in preventing and treating CMD， and explored the strategy of integrating TCM theory with dietary patterns， aiming to establish a new food-nutrition-medicine approach that combines traditional Chinese and western medicine and provide novel insights and directions for the clinical management of CMD.

Establishment and Evaluation of Animal Models of Combined Stasis and Toxin Syndrome / 中国实验方剂学杂志

ObjectiveTo screen and establish animal models of combined stasis and toxin syndrome based on the comparison of three modeling methods， i.e.， carrageenan （Ca）， Ca combined with dried yeast （Ca+Yeast）， and Ca combined with lipopolysaccharide （Ca+LPS）. MethodForty SPF male SD rats were randomly divided into normal group， Ca group， Ca+Yeast group， and Ca+LPS group， with 10 rats in each group. The Ca group， Ca+Yeast group， and Ca+LPS group received an intraperitoneal injection of Ca （10 mg·kg-1） on the first day. The Ca+LPS group received an intraperitoneal injection of LPS （50 μg·kg-1） on the second day， and the Ca+Yeast group received a subcutaneous injection of dry yeast suspension （2 mg·kg-1） on the back on the second day. The rectal temperature of each group was dynamically observed after modeling. After 24 hours of modeling， the macroscopic evaluation indexes， including tongue manifestation， pulse， and black tail length in each group were observed. The PeriCam PSI imaging system was used to detect the blood flow perfusion of the rat tail. The automatic hemorheology analyzer was used to measure the whole blood viscosity and plasma viscosity of each group. The PL platelet function analyzer was used to detect the platelet aggregation rate of the rats. The enzyme-linked immunosorbent assay （ELISA） was used to detect the interleukin-6 （IL-6） level in the rat plasma. The myocardial tissue， brain tissue， and lung tissue of each group of rats were observed by hematoxylin-eosin （HE） staining. ResultCompared with the normal group， all three model groups showed varying degrees of black tail （P<0.05， P<0.01）， reduced blood flow perfusion at the tail end （P<0.05， P<0.01）， decreased R， G， and B values of tongue manifestation （P<0.05， P<0.01）， and increased maximum platelet aggregation rate （P<0.05， P<0.01）. The pulse amplitudes of the Ca+Yeast group and the Ca+LPS group were lower than that of the normal group （P<0.05， P<0.01）. In addition， the average rectal temperature of the Ca+Yeast group increased after 24 hours of modeling （P<0.01）， and the low-， medium-， and high-shear whole blood viscosity and plasma viscosity increased （P<0.05， P<0.01） as compared with those in the normal group. Additionally， the expression level of the plasma inflammatory factor IL-6 was significantly up-regulated （P<0.05）. Pathological morphology results showed that the Ca+Yeast group had the most severe pathological changes， with small foci of myocardial fiber dissolution， inflammatory cell infiltration， and fibroblast proliferation observed. In the hippocampal area， the neurons were sparse and had undergone red degeneration. In the small focus of the lung interstitium， lymphocytes and neutrophils were infiltrated. ConclusionThe animal model of combined stasis and toxin syndrome was properly established using Ca+Yeast.

Background@#and Purpose We aimed to determine the clinical features of Miller Fisher syndrome (MFS) in southern China and compare them with those presenting in other countries. @*Methods@#We collected the medical records of patients diagnosed with MFS during 2013–2016.We analyzed the age, sex, onset season, precursor events, clinical symptoms and signs, findings of nerve conduction studies (NCS), cerebrospinal fluid (CSF), therapeutic remedies, nadir time, and length of hospital stay of patients with MFS in southern China. We concurrently compared the differences between urban and rural areas and between patients with incomplete ophthalmoplegia (IO) and complete ophthalmoplegia (CO). @*Results@#The study enrolled 72 patients: 36 from rural areas and 36 from urban areas, and 50 males and 22 females. The mean age at onset was 47.72 years, and 30 (41.7%) and 21 (29.2%) patients developed MFS in spring and winter, respectively. The typical triad of ophthalmoplegia, ataxia, and areflexia was observed in 50 (69.4%) patients. A history of upper respiratory tract infection 1 week before onset was found in 52.8% of the patients, while 5.6% experienced gastrointestinal infections and 48 (73.8%) exhibited albuminocytological dissociation in the CSF study. Only 26 (36.1%) patients presented abnormalities in NCS. Moreover, restricted outward eyeball movement presented in 83.5% of the patients with classic MFS and acute ophthalmoplegia, and bilateral symmetrical ophthalmoplegia presented in 64.2%. With the exception of the higher proportion of NCS abnormalities in urban areas (47.2% vs. 25.0%), urban and rural differences were insignificant regarding sex ratio, age at onset, high-incidence season, precursor events, disease characteristics, and albuminocytological dissociation in the CSF. Furthermore, patients with CO were older than those with IO (64.53±7.69 vs. 43.19±14.40 years [mean±standard deviation], p<0.001). @*Conclusions@#The patients with MFS were mostly male and middle-aged, and most presented in winter and (especially) spring. More than half of the patients had clear precursor events, most of which were classic MFS with the typical triad. More than 70% of the patients presented albuminocytological dissociation in the CSF. NCS abnormalities were uncommon in MFS. The age at onset was lower in patients with IO than in patients with CO; bilateral symmetrical extraocular muscle paralysis was the most common symptom, and the external rectus was the most frequently involved muscle.

A decade of liver organoids: Advances in disease modeling

Liver organoids are three-dimensional cellular tissue models in which cells interact to form unique structures in culture. During the past 10 years, liver organoids with various cellular compositions, structural features, and functional properties have been described. Methods to create these advanced human cell models range from simple tissue culture techniques to complex bioengineering approaches. Liver organoid culture platforms have been used in various research fields, from modeling liver diseases to regenerative therapy. This review discusses how liver organoids are used to model disease, including hereditary liver diseases, primary liver cancer, viral hepatitis, and nonalcoholic fatty liver disease. Specifically, we focus on studies that used either of two widely adopted approaches: differentiation from pluripotent stem cells or epithelial organoids cultured from patient tissues. These approaches have enabled the generation of advanced human liver models and, more importantly, the establishment of patient-tailored models for evaluating disease phenotypes and therapeutic responses at the individual level.

Study on the Medication Rule of the National Patent of Traditional Chinese Medicine Compound Formula in the Treatment of Depression / 中医杂志

ObjectiveTo explore the medication rules of traditional Chinese medicine compounds for depression in the National Patent Database using data mining， and to provide ideas for the clinical treatment and the development of new drugs for depression. MethodsThe patent data of traditional Chinese medicine compounds for the treatment of depression were searched from inception to July 1st， 2022 on the Patent Publication Announcement website of China National Intellectual Property Administration. The selected traditional Chinese medicine compounds were analyzed by using the data mining section of the ancient and modern medical record cloud platform （V2.3.5） for drug frequency， and based on this， the nature， flavor， channel entry and function of the medicinals were analyzed. Representative high-frequency herbal combinations were obtained through correlation analysis， while the classification of Chinese medicine compounds for depression was analyzed by cluster analysis， and the core combinations of herbs for the treatment of depression were screened out using complex network analysis. ResultsA total of 325 Chinese medicine compounds were included， involving 452 herbs， with a total frequency of 3532 times. The top 10 mostly used herbs were Yujin （Radix Curcumae， 122 times）， Chaihu （Radix Bupleuri， 122 times）， Baishao （Radix Paeoniae Alba， 109 times）， Suanzaoren （Spina Date Seed， 95 times）， Fuling （Poria， 94 times）， Danggui （Radix Angelicae Sinensis， 94 times）， Yuanzhi （Radix Polygalae， 84 times）， Baizhu （Rhizoma Atractylodis Macrocephalae， 72 times）， Shichangpu （Rhizoma Acori Graminei， 71 times）， and Danshen （Salvia Miltiorrhiza， 61 times）. The natures of the herbs were mainly warm （998 times）， neutral （944 times）， slightly cold （596 times） and cold （497 times）； the flavors were mainly sweet （1648 times）， acrid （1392 times）， and bitter （1337 times）； the channels of entry were mainly liver （1695 times）， heart （1521 times）， spleen （1326 times） and lung （1268 times）. The medicinals with the function of soothing liver to relieve constraint， moistening the intestines to promote defecation， calming the heart and the mind， moving qi to relieve constraint were used more frequently. The high frequency herbal combinations by association analysis included “Chaihu （Radix Bupleuri）→ Baishao （Radix Paeoniae Alba）”， “Danggui （Radix Angelicae Sinensis）→Chaihu （Radix Bupleuri）” and “Baishao （Radix Paeoniae Alba）→ Yujin （Radix Curcumae）”. The 22 high frequency medicinals used more than 40 times could be clustered into six categories. Complex network analysis found the core herbal combination for the treatment of depression was the formula of Chaihu （Radix Bupleuri）， Yujin （Radix Curcumae）， Baishao （Radix Paeoniae Alba）， Danggui （Radix Angelicae Sinensis）， Fuling （Poria）， Suanzaoren （Spina Date Seed）， and Xiangfu （Cyperi Rhizoma）. ConclusionTraditional Chinese medicine compounds for the treatment of depression is mainly based on the pathogenesis of constraint， stasis and deficiency， focusing on the liver， heart， spleen and lung， commonly using medicinals with the function of soothing liver to relieve constraint， fortifying spleen and nourishing heart， regulating qi and invigorating blood， and moistening the intestines to promote defecation， which can provide a reference for the clinical treatment and new drug research and development for depression.
