Evidence-Based Dampness-Heat ZHENG (Syndrome) in Cancer: Current Progress toward Establishing Relevant Animal Model with Pancreatic Tumor / 中国结合医学杂志

Cancer is one of the deadliest diseases affecting the health of human beings. With limited therapeutic options available, complementary and alternative medicine has been widely adopted in cancer management and is increasingly becoming accepted by both patients and healthcare workers alike. Chinese medicine characterized by its unique diagnostic and treatment system is the most widely applied complementary and alternative medicine. It emphasizes symptoms and ZHENG (syndrome)-based treatment combined with contemporary disease diagnosis and further stratifies patients into individualized medicine subgroups. As a representative cancer with the highest degree of malignancy, pancreatic cancer is traditionally classified into the "amassment and accumulation". Emerging perspectives define the core pathogenesis of pancreatic cancer as "dampness-heat" and the respective treatment "clearing heat and resolving dampness" has been demonstrated to prolong survival in pancreatic cancer patients, as has been observed in many other cancers. This clinical advantage encourages an exploration of the essence of dampness-heat ZHENG (DHZ) in cancer and investigation into underlying mechanisms of action of herbal formulations against dampness-heat. However, at present, there is a lack of understanding of the molecular characteristics of DHZ in cancer and no standardized and widely accepted animal model to study this core syndrome in vivo. The shortage of animal models limits the ability to uncover the antitumor mechanisms of herbal medicines and to assess the safety profile of the natural products derived from them. This review summarizes the current research on DHZ in cancer in terms of the clinical aspects, molecular landscape, and animal models. This study aims to provide comprehensive insight that can be used for the establishment of a future standardized ZHENG-based cancer animal model.

Investigation on the pharmacological mechanisms of Shirebi granules in treating gouty arthritis with damp-heat syndrome based on crosstalk of Wnt/β-catenin signaling / 药学学报

Gouty arthritis is a type of metabolic rheumatic disease caused by autoimmune abnormalities. Currently, the use of Western medicine in the clinical treatment of gouty arthritis has been associated with a high risk of adverse reactions. Therefore, there is a growing interest in exploring therapeutic drugs from traditional Chinese medicine as a potential alternative. According to the theory of traditional Chinese medicine, gouty arthritis has been classified as damp-heat arthralgia syndrome. Shirebi granules has been found to have good clinical efficacy in treating gouty arthritis. However, its underlying pharmacological mechanisms remain unclear. To address this problem, the study first established the interaction network of candidate targets for Shirebi granules, which is used to treat damp-heat syndrome of gouty arthritis. Then, the key candidate targets of Shirebi granules for treating gouty arthritis with damp-heat syndrome were screened by calculating the topological features of the network nodes. Then, the functional mining of the key candidate targets revealed that the candidate targets of Shirebi granules may intervene in the biological process of inflammatory response and lipid metabolism through the crosstalk of Wnt/β-catenin signaling. To verify the effectiveness of Shirebi granules in treating gouty arthritis with damp-heat syndrome, a rat model was established. The results demonstrated that the granules significantly improved the severity of arthritis in rats with this condition, reduced joint inflammation, gait score, swelling index, increased mechanical pain threshold (P < 0.05), and reduced the content of serum inflammatory factors IL-1β, IL-6, and TNF-α in gouty arthritis rats with damp-heat syndrome (P < 0.01) gouty. It was also found that Shirebi granules effectively alleviated the symptoms of dampness heat syndrome such as local joint fever and dry mouth by reducing the temperature of the joints in acute gouty arthritis with damp-heat syndrome (AD) rats, increasing the threshold of heat pain, increasing water intake (P < 0.01), and inhibiting abnormal changes in the content of fatty acid oxidation related enzymes (P < 0.01). Western blot analysis showed that Shirebi granules increased the protein expression levels of Wnt and β-catenin (P < 0.01) while decreasing the protein expression of p65, p-p65 and PPARγ (P < 0.01) in rats with gouty arthritis and damp-heat syndrome. The results showed that Shirebi granules may reverse the "inflammation-immune" imbalance and lipid metabolism disorder by regulating the crosstalk of Wnt/β-catenin signaling, and play a role in alleviating the severity of the disease. This study provides a methodological reference for elucidating the pharmacological mechanisms of traditional Chinese medicine formulas. It also presents research ideas for the appropriate clinical use of Chinese patent medicines and the development of new clinical drugs for gouty arthritis therapy. The animal welfare and experiment procedures of this study were performed in accordance with the regulations of the Experimental Animal Ethics Committee of Experimental Research Center, China Academy of Chinese Medical Sciences (grant No. ERCCACMS11-2302-08).

A Retrospective Clinical Study on the Correlation between the Theory of Five Movements and Six Climates， and Kidney Deficiency with Governor Vessel Cold Syndrome and Kidney Deficiency Damp-Heat Syndrome in Ankylosing Spondylitis / 中医杂志

ObjectiveTo explore the relationship between the kidney deficiency and governor vessel cold syndrome and the kidney deficiency damp-heat syndrome in ankylosing spondylitis （AS） patients and the five evolutive phases and six climatic factors of their birth and onset year based on the theory of five movements and six climates （FMSC）. MethodsTotally 1791 patients with AS who were admitted to China-Japan Friendship Hospital from September 2010 to September 2020 and met the diagnostic and inclusion criteria were selected in this study. The clinical data were classified into two types of syndromes， kidney deficiency and governor vessel cold syndrome and the kidney deficiency damp-heat syndrome based on the diagnostic criteria of traditional Chinese medicine syndromes. The date of birth and the year of disease onset were converted into FMSC symbols according to the perpetual almanac （《万年历》）， and the two could be converted into the terrestrial branch， year evolutive phase， host evolutive phase， guest evolutive phase， host climatic qi， guest climatic qi， celestial manager qi， guest climatic qi adding to fixed host qi， combined analysis of five evolutive phases and six climatic factors， solar terms， and season of the date of birth， as well as the terrestrial branch， year evolutive phase， and celestial manager qi of the year of disease onset. Univariate analyses were performed using the two independent samples t-test or the Mann Whitney U-test， the Pearson （Pearson） χ2 test， or one-way logistic regression analyses， and variables for which statistical significance existed in the one-way analyses were included in the multivariate logistic regression analyses. General conditions， clinical manifestations， physical signs， laboratory indicators ［including C reactive protein （CRP）， erythrocyte sedimentation rate （ESR）， and humans leukocyte antigen B27 （HLA-B27）］， measurement （including occipital wall distance， jaw peduncle distance， finger-to-ground distance， thoracic range of motion， and Schober experiment）， and distribution of FMSC of birth and disease onset between AS patients with kidney deficiency and governor vessel cold syndrome and with the kidney deficiency damp-heat syndrome were compared， and the association between FMSC and AS patients with kidney deficiency and governor vessel cold syndrome and the kidney deficiency damp-heat syndrome was studied. ResultsThe differences in ESR， CRP， chest mobility， occurrence of achilles tendon enthesitis， and peripheral arthritis between the two groups of patients were statistically significant （P＜0.05）. Single factor analysis found that taking kidney deficiency and governor vessel cold syndrome as control the following FMSC factors increases the risk of developing kidney deficiency damp-heat syndrome： excess of water in year evolutive phase at birth， excess of wood in host evolutive phase at birth， excess of wood in guest evolutive phase at birth， excess of wood in year evolutive phase of onset， deficiency of metal in year evolutive phase at birth （OR = 2.000， P = 0.004）， excess of metal in host evolutive phase at birth （OR = 1.745， P = 0.024） or excess of wood （OR = 1.781， P = 0.023）， deficiency of fire in guest evolutive phase at birth （OR = 1.689， P = 0.049） or deficiency of wood （OR = 1.901， P = 0.018） or excess of metal （OR = 2.163， P = 0.004）， excess of water in year evolutive phase at the disease onset （OR = 1.880 ， P = 0.013） or deficiency of wood （OR = 1.707， P = 0.022）. Multivariate logistic regression analysis found that the risk of developing kidney deficiency damp-heat syndrome in AS was increased by deficiency of metal in year evolutive phase at birth， excess of metal in host evolutive phase at birth， higher level of ESR， greater the chest mobility， incidence of concomitant Achilles tendon enthesitis and peripheral arthritis. ConclusionThe year evolutive phase and host evolutive phase at birth play a significant role in the development of kidney deficiency and governor vessel cold syndrome AS. Risk of developing kidney deficiency damp-heat syndrome can be increased by excess of water or deficiency of metal in year evolutive phase at birth， and excess of wood or excess of metal in host evolutive phase at birth and the kidney deficiency damp-heat syndrome in ankylosing spondylitis.

ObjectiveTo compare the diagnostic accuracy of five different weighting methods of Chinese medicine syndrome and then analyze their diagnostic efficacy and characteristics， by taking Diagnostic Standard for Type 2 Diabetes Mellitus （T2DM） with Dampeness-heat Syndrome （abbreviated as diagnostic standard） as an example. MethodsData from expert questionnaire on the diagnostic standard and a cross-sectional survey of 1021 patients were collected. The comparative diagnostic test accuracy （CDTA） method was used to calculate the area under the ROC curve （AUC）， area under the PR curve （AUPR）， accuracy （ACC）， sensitivity， and specificity of five commonly used weighting methods in two categories， including knowledge-driven weighting methods （expert scoring synthesis method， analytic hierarchy process， and precedence chart method） and data-driven weighting methods （logistic regression contribution method and entropy weighting method）. ResultsAmong 1021 patients with T2DM， 389 cases were diagnosed as dampness-heat syndrome. The expert scoring synthesis method， analytic hierarchy process method， and precedence chart method were basically consistent in the weight scores of each item. The expert scoring comprehensive method， analytic hierarchy process method， and entropy weighting method have a smaller difference in the weight scores of each item， while there was larger difference in the weight scores of each item of the precedence chart method and the logistic regression contribution method. The AUC （95% CI）， AUPR， ACC， sensitivity， and specifi-city of the expert scoring synthesis method were 0.913 （0.893， 0.932）， 0.851， 0.870， 0.868 and 0.875， respectively； while those of the analytic hierarchy process method were 0.910 （0.890， 0.930）， 0.838， 0.879， 0.848 and 0.896； of the precedence chart method were 0.919 （0.900， 0.937）， 0.858， 0.875， 0.871 and 0.875； of the logistic regression contribution method were 0.867 （0.842， 0.891）， 0.792， 0.853， 0.769 and 0.898； and of the entropy weighting method were 0.895 （0.873， 0.916）， 0.820， 0.869， 0.802 and 0.908. ConclusionThe knowledge-driven weighting methods are better than the data-driven weighting methods in terms of diagnostic efficacy and reflecting expert experience.

Effect of different suspension moxibustion methods on syndrome characteristics of rats with rheumatoid arthritis of heat bi syndrome based on "moxibustion can be used for heat syndrome" / 中国针灸

OBJECTIVE@#To observe the effects of different suspension moxibustion methods on the syndrome characteristics and inflammatory factors of rats with rheumatoid arthritis (RA) of heat bi syndrome and to prove the concept of "moxibustion can be used for heat syndrome".@*METHODS@#Among seventy Wistar rats, 12 rats were randomly selected as a normal group, and the remaining rats were induced by collagen combined with wind, dampness, and heat environmental stimulation to establish the RA model of heat bi syndrome. Forty-eight rats with successful model establishment were further randomly divided into a model group and three moxibustion groups (mild moxibustion group, rotating moxibustion group and sparrow-pecking moxibustion group), with 12 rats in each group. The acupoints "Quchi" (LI 11), "Dazhui" (GV 14) and ashi point were used in all moxibustion groups, with mild moxibustion, rotating moxibustion, and sparrow-pecking moxibustion intervention given respectively, each acupoint was treated with moxibustion for 10 min a day, and 6 days were considered one course of treatment, with a total of three courses. After the intervention, the arthritis index (AI), the Evans blue (EB) extravasated volume in the soft tissue of the right hind paw, and the levels of tumor necrosis factor (TNF)-α and interleukin (IL)-10 in the serum were measured by ELISA in each group. The volume of the bilateral hind paw was measured; the infrared thermal imaging was collected to analyze the temperature of the plantar area of the bilateral foot pads, and the reaction time of plantar heat pain was calculated before and after modeling, as well as after the 1st, 2nd and 3rd courses of interrention. The ankle dorsiflexion angle of the right hind foot was also measured before and after modeling, as well as after the intervention.@*RESULTS@#After modeling, compared with the normal group, the rats in the model group had more high-temperature areas in the bilateral hind limbs, abnormal AI score, abnormal bilateral hind paw volume, abnormal temperature of the plantar area of the bilateral foot pads, abnormal foot pain response time, abnormal right hind ankle dorsiflexion angle, abnormal right hind paw soft tissue EB extravasation, and abnormal serum TNF-α and IL-10 levels (P<0.01, P<0.05). After the intervention, compared with the model group, the rats in each moxibustion group had decreased or disappeared high-temperature areas in the bilateral hind limbs, EB extravasated volume in the soft tissue of the right hind paw was reduced (P<0.05), and the right ankle dorsiflexion angle was increased (P<0.05), serum level of TNF-α was reduced, and level of IL-10 increased (P<0.05); the AI scores in the mild moxibustion group and the sparrow-pecking moxibustion group was decreased (P<0.01, P<0.05). After the 1st, 2nd and 3rd courses of intervention, compared with the model group, the bilateral hind paw volume of rats in each moxibustion group was decreased (P<0.05, P<0.01), and plantar heat pain reaction time was increased (P<0.05). After the 2nd course and the 3rd course of intervention, the temperature of the right hind paw pad area was decreased in each moribustion group (P<0.05); after the 3rd courses of intervention, the temperature of the left hind paw pad area was decreased in the mild moxibustion group (P<0.05).@*CONCLUSION@#Suspension moxibustion could adjust the serum levels of TNF-α and IL-10 to improve the syndrome characteristics of RA rats of heat bi syndrome, such as joint redness, swelling, heat, pain and activity restriction. The effect of mild moxibustion is the most prominent. The findings could provide scientific basis for "moxibustion can be used for heat syndrome".

Study on active components and mechanism of shikonin in prevention and treatment of blood heat syndrome / 中国药理学通报

Aim To systematically evaluate the heat-clearing mechanism of Arnebiae Radix on two mouse models of blood heat syndrome. Methods The drug-forming molecules were screened by comprehensive network pharmacology methods, and the correlation between drug efficacy and related factors and targets was evaluated on the mouse model of short effect blood heat syndrome constructed by 2, 4-dinitrophenol (DNP) and the mouse model of severe blood heat syndrome (heat stroke) constructed by high temperature combined with lipopolysaccharide (LPS). Results A total of 277 shikonin related targets were collected, mainly involving biological processes such as inflammatory reaction, oxidation reaction and coagulation reaction. Shikonin, a representative compound, significantly improved the main syndromes of mice with blood heat syndrome, reduced the levels of inflammatory factors IL-1β, IL-6 and TNF-α in the two models, and reduced the contents of oxidative damage indexes LPO and MDA, and the two showed correlation. The main mechanism was to inhibit the expression of NF-ΚB p65 and up-regulate the expression of Nrf2. Conclusions Shikonin plays a pharmacological role in the prevention and treatment of blood heat syndrome by inhibiting inflammation and improving antioxidant capacity, which provides a pharmacological basis for shikonin in the prevention and treatment of blood heat syndrome.

Correlation of traditional Chinese medicine to reduced re-admission risk in ankylosing spondylitis patients with dampness-heat syndrome: a retrospective cohort study / 中国中药杂志

This study aimed to analyze the impact of traditional Chinese medicine(TCM) on the risk of re-admission for ankylosing spondylitis(AS) patients with dampness-heat syndrome. In this study, a telephone follow-up was conducted on 1 295 AS inpatients, and after screening and exclusions, 1 044 successfully followed-up patients were included. A retrospective cohort study was conducted using propensity score matching(PSM), and a Cox proportional risk model was employed to assess the effect of various factors on the risk of re-admission for AS patients with dampness-heat syndrome. Kaplan-Meier survival curves were used to analyze the effect of TCM intervention time on re-admission. The incidence rate of dampness-heat syndrome in AS patients was found to be 51.3% in this study. After 1∶1 PSM, 385 AS patients with dampness-heat syndrome and 385 AS patients without dampness-heat syndrome were included for analysis. The results indicated that the re-admission rate was higher for patients with dampness-heat syndrome compared with those without dampness-heat syndrome(P<0.05). AS patients with dampness-heat syndrome in the TCM group had a lower admission rate than those in the non-TCM group(P=0.01). The cox proportional risk model demonstrated that TCM was an independent protective factor, as it reduced the risk of re-admission by 35%(HR=0.35, 95%CI[0.26, 0.95], P<0.05). Moreover, the subgroup with high exposure(time to use Chinese medicine >12 months) had a significantly lower risk of re-admission than that with low TCM exposure(time to use Chinese medicine ≤12 months). The re-admission rate for AS patients with dampness-heat syndrome was higher than that without dampness-heat syndrome, and TCM was identified as a protective factor in reducing the risk of re-admission. Furthermore, a longer duration of TCM intervention was associated with a lower risk of re-admission.

Gender differences in antidepressant effect of raw Rehmanniae Radix / 中国中药杂志

For the first time, this study evaluated the gender differences and mechanisms of the antidepressant effects of raw Rehmanniae Radix(RRR) based on the classic depression model with traditional Chinese medicine syndrome of Yin deficiency and internal heat. The depression model with Yin deficiency and internal heat was established by the widely recognized and applied method of thyroxine induction of the classic depression model with Yin deficiency and internal heat(chronic unpredictable mild stress). Male and female mice were simultaneously treated with RRR. The study analyzed indicators of nourishing Yin and clearing heat, conventional antidepressant efficacy test indicators, and important biomolecules reflecting the pathogenesis and prevention and treatment mechanisms of depression, and conducted a correlation analysis of antidepressant efficacy, Yin-nourishing and heat-clearing efficacy, and biological mechanism in different genders, thereby comprehensively assessing the antidepressant effects of RRR on depression of Yin deficiency and internal heat, as well as its gender differences and mechanisms. RRR exhibited antidepressant effects in both male and female mouse models, and its antidepressant efficacy showed gender differences, with a superior effect observed in females. Moreover, the effects of RRR on enhancing or improving hippocampal neuronal pathology, nucleus-positive areas, postsynaptic dense area protein 95, and synaptophysin protein expression were more significant in females than in males. In addition, RRR significantly reversed the abnormal upregulation of nuclear factor(NF)-κB/cyclooxygenase 2(COX2)/NOD-like receptor thermal protein domain associated protein 3(NLRP3) pathway proteins in the hippocampus of both male and female mouse models. The antidepressant effects of RRR were more pronounced in depression female mice with Yin deficiency and internal heat syndrome, possibly due to the improvement of neuronal damage and enhancement of neuroplasticity. The antidepressant mechanisms of RRR for depression with Yin deficiency and internal heat syndrome may be associated with the downregulation of the NF-κB/COX2/NLRP3 pathway to reduce neuronal damage and enhance neuroplasticity.

Clinical symptoms and distribution characteristics traditional Chinese medicine syndromes of pulmonary nodules / 中国中药杂志

A cross-sectional study method combined with two types of traditional Chinese medicine(TCM) syndrome differentiation methods was adopted to investigate the clinical symptoms and distribution characteristics of TCM syndromes in patients with pulmonary nodules from the perspectives of number, size, nature, and stability of pulmonary nodules by using the χ~2 test, systematic clustering and Apriori algorithm correlation analysis. The common clinical symptoms of pulmonary nodules were fatigue(77.35%) and irritability(75.40%), and 40 symptoms were clustered into 3 groups(digestive system symptoms, respiratory system symptoms, and emotional and systemic symptoms) and 8 major symptom categories. The proportion of cold and heat in complexity syndrome(63.43%) was higher based on cold-heat syndrome differentiation. The top two syndromes were Qi deficiency syndrome(88.03%) and Qi depression syndrome(83.17%) based on disease syndrome differentiation. Yang deficiency syndrome(60.52%) was more than Yin deficiency syndrome(50.16%). There were higher proportions of phlegm syndrome(78.67%) and Yang deficiency syndrome(69.33%) of so-litary pulmonary nodules in terms of the number of pulmonary nodules. In terms of size, the proportion of phlegm syndrome decreased as the mean diameter of pulmonary nodules increased, while the proportions of Yang deficiency syndrome and blood stasis syndrome increased. The distribution of Qi depression syndrome was more in those with mean diameter<10 mm(85.02%, P=0.044) and cold syndrome was more in those with mean diameter ≥10 mm(16.67%, P=0.024). In terms of the nature of pulmonary nodules, the proportions of Qi depression syndrome and heat syndrome decreased with the increase in solid components of pulmonary nodules, while the proportions of Yin deficiency syndrome and cold and heat in complexity syndrome increased. The blood stasis syndrome accounted for a higher proportion of pulmonary nodules with solid components. In terms of the stability of pulmonary nodules, dampness syndrome(72.97%), blood stasis syndrome(37.84%), and cold and heat in complexity syndrome(70.27%) accounted for higher proportions. In addition, patients with new nodules presented higher proportions in Qi inversion syndrome(52.00%, P=0.007) and cold and heat in complexity syndrome(66.00%, P=0.008). Meanwhile, 11 syndromes were associated and 4 common compound syndromes were obtained(Qi deficiency and depression syndrome, Qi depression and phlegm coagulation syndrome, Qi deficiency and phlegm coagulation syndrome, and Qi deficiency and dampness obstruction syndrome). Qi deficiency syndrome and Qi depression syndrome could be associated with other syndromes. The results show that the main clinical symptoms of pulmonary nodules are fatigue and irritability. The main TCM syndromes of pulmonary nodules are Qi deficiency syndrome, Qi depression syndrome, Yang deficiency syndrome, and cold and heat in complexity syndrome. The distribution of TCM syndromes is significantly correlated with the size of pulmonary nodules and the presence or absence of new nodules. The common compound syndromes are Qi deficiency and depression syndrome, Qi depression and phlegm coagulation syndrome, Qi deficiency and phlegm coagulation syndrome, and Qi deficiency and dampness obstruction syndrome.

Metabolomic Analysis of Urine in Rat Model with Spleen-stomach Damp-heat Syndrome / 中国实验方剂学杂志

ObjectiveTaking the rat model of spleen-stomach damp-heat syndrome（SSDHS） as the research object， this study aimed to investigate the potential biomarkers of SSDHS and the related metabolic pathways based on urine metabolomics， and tried to reveal the essence of SSDHS at the level of endogenous small molecular metabolites. MethodSixteen SD rats were randomly divided into normal and model groups. The normal group was fed normal chow and the model group was fed with 200 g·L-1 honey water daily， and lard and Chinese Baijiu alternately on alternate days for 17 days. The SSDHS model rats were exposed to external dampness-heat environment with temperature at 30-34 ℃， relative humidity of 95% for 2 h at the same time every day from the 10th day for 7 d. Then， the model was evaluated by observing the general conditions of the rats， measuring the contents of motilin（MTL） and gastrin（GT） in plasma by enzyme-linked immunosorbent assay（ELISA）， and examining the histopathology of gastronitestinal tissues. In additon， the urine metabolomics analysis was performed by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）， and the detection conditions was as follows：ACQUITY™ UPLC BEH C18 column（2.1 mm×100 mm， 1.7 μm）， mobile phase of 0.1% formic acid aqueous solution（A）-0.1% formic acid acetonitrile solution（B） for gradient elution （0-3 min， 1%-18%B； 3-8 min， 18%-40%B； 8-10 min， 40%-100%B）， the flow rate of 0.4 mL·min-1， electrospray ionization（ESI） in positive and negative ion modes， scanning range of m/z 50-1 000. The univariate and multivariate statistical analysis were constructed for screening inter-group differential ions， the element composition was calculated according to the precise relative molecular weight， and ion information was matched with databases such as Human Metabolome Database（HMDB） to identify biomarkers. Kyoto Encyclopedia of Genes and Genomes（KEGG） database was used to obtain the biological information of metabolites， and their associated metabolic pathways were analyzed by MetaboAnalyst 5.0. ResultCompared with the normal group， the rectal temperature of the model group increased significantly（P<0.01）， the levels of plasma MTL and GT decreased significantly（P<0.05， P<0.01）， and pathological changes such as bleeding， congestion and inflammatory infiltration in the gastric and colonic tissues. A total of 25 differential metabolites such as L-histidine， citric acid and isocitric acid were found to be the potential biomarker of SSDHS by urine metabolomics， 13 of which were phase Ⅱ metabolites of endogenous substances（glucuronic acid conjugates， sulfuric acid conjugates and acetyl conjugates）， involving the metabolic pathways of histidine metabolism， tricarboxylic acid cycle， glyoxylate and dicarboxylate metabolism. ConclusionSSDHS primarily causes disorders of histidine metabolism， tricarboxylic acid cycle， glyoxylate and dicarboxylate metabolism， as well as the imbalance of the activation/inactivation of endogenous metabolites， which may involve the immune response， material and energy metabolism， inflammatory response and intestinal flora， and may provide a basis for the establishment and application of SSDHS model.

Regan Syrup has the effect of clearing heat, releasing exterior, benefiting pharynx and relieving cough, and previous phase Ⅱ clinical trial showed that the efficacy of Regan Syrup high-dose and low-dose groups was better than that of the placebo group, and there was no statistically significant difference in the safety between the three groups. The present study was conducted to further investigate the efficacy and safety of the recommended dose(20 mL) of Regan Syrup in the treatment of common cold(wind-heat syndrome). Patients who met the inclusion and exclusion criteria were selected and divided into the test group(Regan Syrup+Shufeng Jiedu Capsules placebo), positive drug group(Regan Syrup placebo+Shufeng Jiedu Capsules) and placebo group(Regan Syrup placebo+Shufeng Jiedu Capsules placebo) at a 1∶1∶1 using a block randomization method. The course of treatment was 3 days. A total of 119 subjects were included from six study centers, 39 in the test group, 40 in the positive drug group and 40 in the placebo group. The onset time of antipyretic effect was shorter in the test group than in the placebo group(P≤0.01) and the positive drug group, but the difference between the test group and the positive drug group was not significant. The test group was superior to the positive drug group in terms of fever resolution(P<0.05), and had a shorter onset time of fever resolution than the placebo group, but without obvious difference between the two groups. Compared to the positive drug group, the test group had shortened disappearance time of all symptoms(P≤0.000 1). In addition, the test group was better than the positive drug group and the placebo group in relieving symptoms of sore throat and fever(P<0.05), and in terms of clinical efficacy, the recovery rate of common cold(wind-heat syndrome) was improved in the test group compared to that in the placebo group(P<0.05). On the fourth day after treatment, the total TCM syndrome score in both test group and positive drug group was lower than that in the placebo group(P<0.05). There was no significant difference in the incidence of adverse events between three groups and none of them experienced any serious adverse events related to the study drug. The results indicated that Regan Syrup could shorten the onset time of antipyretic effect, reduce the time of fever resolution, alleviate the symptoms such as sore throat and fever caused by wind-heat cold, reduce the total score of Chinese medicine symptoms, and improve the clinical recovery rate with good safety.

Discussion on Treatment of Diarrhea of Intestinal Dampness-heat Syndrome and of Cold-dampness Disturbing Spleen Syndrome with Different Methods： Based on Intestinal Microbiota Function / 中国实验方剂学杂志

ObjectiveTo study the changes of microbiota in different intestinal niches in the instance of diarrhea with intestinal dampness-heat syndrome and cold-dampness disturbing spleen syndrome， so as to provide objective evidence for treating diarrhea with different methods from the perspective of intestinal flora. MethodThe 16S rRNA gene high-throughput sequencing data of model mice with diarrhea of the two syndromes and the model mice after prescription intervention were retrieved from National Center for Biotechnology Information （NCBI）， and the intestinal dominant bacteria and microbial functions were compared among groups. Spearman's correlation coefficient among the microorganisms in each group was calculated and the co-occurrence networks of intestinal microbiota were constructed to study the interaction of the microbiota. ResultThe microbiota imbalance in intestinal contents of mice with diarrhea of intestinal dampness-heat syndrome was characterized by the enrichment of Muribaculum and Aerococcus， while the imbalance in intestinal mucosa was manifested by the enrichment of Gram-negative Neisseria， Capnocytophaga， and Prevotella （P<0.05）. However， after the treatment with Gegen Qinliantang， the microbiota in two distinct ecosystems was characterized by the enrichment of Lactobacillus and the abundance of Streptococcus in intestinal mucosa was increased. The microbiota imbalance in intestinal contents of diarrhea with cold-dampness disturbing spleen syndrome was characterized by the enrichment of Lactobacillus （P<0.01） and Clostridium sensu stricto 1， while the intestinal mucosa was dominated by the increase of Candidatus arthromitus and Enterobacter. However， after the treatment with Huoxiang Zhengqi powder， the intestinal contents were characterized by Lactobacillus enrichment， while the intestinal mucosal flora was featured by the enrichment of C. arthromitus， Pseudomonas， and Bacillus. Overall， the contribution of dominant bacteria in intestinal mucosa to the difference was higher than that in intestinal contents， and more dominant bacteria in the intestinal mucosa interacted with other bacteria. ConclusionMicrobiota imbalance is different for diarrhea of different syndromes， and the therapeutic effects of corresponding prescriptions are also different. In addition， the microbiota imbalance has different characteristics between intestinal niches for mice with diarrhea of the same syndrome. Therefore， intestinal flora may be one of the biological bases for exploring the characteristics of "treating the diarrhea with different methods" in Chinese medicine.

Effect of Modified Da Chaihutang on FXR/FGF15/FGFR4 Signaling Pathway in Mice with Cholesterol Gallstone Differentiated into Damp-Heat Syndrome / 中国实验方剂学杂志

ObjectiveTo observe the effect of modified Da Chaihutang on cholesterol gallstone （CS） in mice due to damp-heat based on the farnesoid X receptor （FXR）/fibroblast growth factor 15 （FGF15）/fibroblast growth factor receptor 4 （FGFR4） pathway and explore the molecular biological mechanisms of CS differentiated into damp-heat syndrome from the perspective of correspondence between prescription and syndrome. MethodForty-eight six-week-old mice were randomly divided into the blank group， model group， modified Da Chaihutang （23.4 g·kg-1） group， and ursodeoxycholic acid （0.12 g·kg-1） group， with 12 mice in each group. The ones in the latter three groups were exposed to "internal dampness + external dampness + high-cholesterol diet" for 12 weeks for inducing CS due to damp-heat. Mice in the modified Da Chaihutang group and ursodeoxycholic acid group were gavaged with the corresponding drugs， while those in the model and blank groups with the same amount of normal saline for a total of four weeks. Before and after modeling， mice in each group were subjected to open field tests for determining their activities and mental states. Such general conditions as body mass， food intake， fur， and urine and stool of mice in each group were observed and recorded weekly for judging the damp-heat syndrome. After the intervention， the sampled liver and gallbladder tissues of mice in each group were stained with hematoxylin-eosin （HE） staining， and the serum γ-glutamyltransferase （GGT）， alkaline phosphatase （ALP）， and total bilirubin （TBIL） were determined. The total cholesterol （TC） and total bile acid （TBA） contents in bile were measured by enzyme-linked immunosorbent assay （ELISA）. The mRNA and protein expression levels of FXR， FGF15， FGFR4， and cholesterol 7α-hydroxylase gene （CYP7A1） were assayed by real-time fluorescence quantitative polynucleotide chain reaction （Real-time PCR） and Western blot. ResultCompared with the blank group， the model group exhibited enlarged gallbladder， brown turbid bile with flocculent precipitation visible to the naked eye， obvious damp-heat syndrome， lipoid degeneration in the liver tissue， rough and thickened gallbladder wall， elevated ALP， GGT， and TBIL in serum （P<0.01） and TC in bile （P<0.01）， reduced TBA （P<0.01）， up-regulated FXR， FGF15， and FGFR4 mRNA and protein expression in ileum （P<0.05， P<0.01）， and down-regulated CYP7A1 mRNA and protein expression （P<0.01）. Compared with the model group， the two medication groups displayed improved bile turbidity， and the bile in the modified Da Chaihutang group became clearer. After intervention， the damp-heat syndrome of mice in the modified Da Chaihutang group was significantly alleviated. The liver and gallbladder lesions of mice in the two medication groups were significantly relieved， manifested as reduced serum ALP， GGT， and TBIL （P<0.01）. The reduction in ALP and TBIL of the modified Da Chaihutang group was more significant （P<0.01）. The TC contents in the bile of mice from the two medication groups were significantly lowered， whereas the TBA contents were elevated （P<0.01）， with more significant changes present in the modified Da Chaihutang group （P<0.01）. The mRNA and protein expression levels of FXR， FGF15， and FGFR4 in the modified Da Chaihutang group were down-regulated （P<0.05， P<0.01）， while the mRNA and protein expression levels of CYP7A1 rose （P<0.05）， except that the elevation in FGF15 and FGFR4 protein expression and reduction in CYP7A1 protein expression were not significant. The mRNA and protein expression levels of FXR， FGF15， and FGFR4 in the ursodeoxycholic acid group all decreased， among which the reduction in FXR was remarkable （P<0.05）， and the mRNA and protein expression levels of CYP7A1 were significantly up-regulated （P<0.05）. ConclusionModified Da Chaihutang significantly improves the stone， liver function， bile composition， abnormal cholesterol-bile acid metabolism， and damp-heat syndrome in the model mice of CS differentiated into damp-heat syndrome， which may be related to its regulation of key factors FXR， FGF15， FGFR4， and CYP7A1 mRNA and protein expression in the cholesterol-bile acid metabolism pathway.

Objective To investigate the regulatory effect of Jiedu Huayu Tongfu prescription on intestinal homeostasis in patients with hepatitis B cirrhosis with liver-gallbladder damp-heat syndrome, as well as its effect on endotoxin, inflammatory factors, and cellular immune function. Methods A total of 72 patients who attended The First Affiliated Hospital of Henan University of Chinese Medicine from June 2019 to January 2021 and met the diagnostic and inclusion criteria were enrolled as subjects and then randomly divided into observation group and control group, with 36 patients in each group. In the treatment group, 2 patients were lost to follow-up, 2 patients were excluded, and 32 patients completed the study; in the control group, 2 patients were lost to follow-up, 1 patient was excluded, and 33 patients completed the study. In addition to the basic treatment including antiviral therapy and liver-protecting treatment, the patients in the observation group were given Jiedu Huayu Tongfu granules, and those in the control group were given oral administration of Bifidobacterium tetravaccine tablets; the course of treatment was 4 weeks for both groups. The 16S rDNA sequencing technique was used for sequencing of fecal flora, and the two groups were measured in terms of the changes in liver function [alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), and albumin (Alb)], endotoxin (ET), levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), and T lymphocyte subsets (CD3 + T, CD4 + T, CD8 + T, and CD4 + /CD8 + ) after treatment. For normally distributed continuous data with homogeneity of variance, the paired t -test was used for comparison within each group, and the independent samples t -test was used for comparison between two groups; the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data. The chi-square test was used for comparison of categorical data. Results The observation group had a significantly higher overall response rate than the control group (87.5% vs 60.6%, χ 2 =-2.299, P =0.022). After treatment, both groups had significant reductions in ALT, AST, and TBil and a significant increase in Alb (all P 0.05). Conclusion Jiedu Huayu Tongfu prescription, in combination with etiological and basic treatments, can alleviate clinical symptoms, reduce liver injury, and improve cellular immune function in patients with hepatitis B cirrhosis with liver-gallbladder damp-heat syndrome. Jiedu Huayu Tongfu prescription can improve the imbalance of intestinal flora by increasing the abundance of the probiotic bacteria such as Firmicutes, Lactobacillus, and Bifidobacterium and the pathogenic bacteria such as Bacteroidetes and Cercozoa, and its effect in further improving liver and immune function may be associated with the regulation of intestinal microecology.
