Protective mechanism of Yinchenzhufu decoction against cholestatic liver injury induced by lithic acid based on network pharmacology / 药学学报

Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1β, non-receptor tyrosine kinase Src, interleukin-6, etc. GO (gene ontology) and KEGG (kyoto encyclopedia of genes and genomes) enrichment analysis indicated that YCZFD may regulate the tumor necrosis factor signaling pathway, nuclear factor-κB signaling pathway, bile secretion, and other related factors to ameliorate the cholestatic liver injury. AutoDockTools software was used to perform molecular docking verification on the core targets and components of YCZFD. To verify the results of network pharmacology, UPLC-MS/MS method was used to determine the effect of YCZFD on levels of bile acid profiles in mouse liver tissues. It was found that treatment with YCZFD significantly reduced the content of free bile acids, taurine bound bile acids, and total bile acids in the liver tissues of cholestatic mice. Then, results from real time PCR and Western blot also found that YCZFD can upregulate the expression of hepatic nuclear receptor farnesoid X receptor, metabolizing enzyme (UDP glucuronidase transferase 1a1), and efflux transporters (bile salt export pump, multidrug resistance-associated protein 2, multidrug resistance-associated protein 3, etc) in cholestasis mice, promote bile acid metabolism and excretion, and improve bile acid homeostasis. Moreover, YCZFD can also inhibit pyroptosis and inflammation by regulating NOD-like receptors 3 pathway, thereby inhibiting cholestatic liver injury.

The specificity of body surface temperature of relevant back-shu points in patients with chronic persistent asthma based on infrared thermal imaging technology / 中国针灸

OBJECTIVE@#To detect the body surface temperature of the relevant back-shu points in patients with chronic persistent asthma by infrared thermal imaging technology, and observe the specific changes of the body surface temperature of the relevant back-shu points under the condition of lung disease.@*METHODS@#Forty-five patients with chronic persistent asthma (observation group) and 45 healthy subjects (control group) were selected. The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) were measured by BK-MT02A medical infrared thermography.@*RESULTS@#The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in the observation group was higher than that in the control group (P<0.01, P<0.05). The body surface temperature of bilateral Feishu (BL 13) and Geshu (BL 17) was higher than that of ipsilateral Pishu (BL 20) and Shenshu (BL 23) in the two groups (P<0.01, P<0.05). There was no statistically significant difference in body surface temperature between ipsilateral Feishu (BL 13) and Geshu (BL 17), between ipsilateral Pishu (BL 20) and Shenshu (BL 23) (P>0.05).@*CONCLUSION@#The pathological increase of body surface temperature of Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in patients with chronic persistent asthma indicates that above acupoints have specificity in reflecting lung diseases. The Feishu (BL 13) and Geshu (BL 17), which have significantly increased body surface temperature, not only provide objective basis for the pathological pathogenesis of "deficiency in origin and excess in symptom" in patients with chronic persistent asthma, but also reflect the different expressions of different acupoints on the same meridian for the lung diseases.

Components of drugs in acupoint sticking therapy and its mechanism of intervention on bronchial asthma based on UPLC-Q-TOF-MS combined with network pharmacology and experimental verification / 中国中药杂志

UPLC-Q-TOF-MS combined with network pharmacology and experimental verification was used to explore the mechanism of acupoint sticking therapy(AST) in the intervention of bronchial asthma(BA). The chemical components of Sinapis Semen, Cory-dalis Rhizoma, Kansui Radix, Asari Radix et Rhizoma, and Zingiberis Rhizoma Recens were retrieved from TCMSP as self-built database. The active components in AST drugs were analyzed by UPLC-Q-TOF-MS, and the targets were screened out in TCMSP and Swiss-TargetPrediction. Targets of BA were collected from GeneCards, and the intersection of active components and targets was obtained by Venny 2.1.0. The potential targets were imported into STRING and DAVID for PPI, GO, and KEGG analyses. The asthma model induced by house dust mite(HDM) was established in mice. The mechanism of AST on asthmatic mice was explored by pulmonary function, Western blot, and flow cytometry. The results indicated that 54 active components were obtained by UPLC-Q-TOF-MS and 162 potential targets were obtained from the intersection. The first 53 targets were selected as key targets. PPI, GO, and KEGG analyses showed that AST presumedly acted on SRC, PIK3 CA, and other targets through active components such as sinoacutine, sinapic acid, dihydrocapsaicin, and 6-gingerol and regulated PI3 K-AKT, ErbB, chemokine, sphingolipid, and other signaling pathways to intervene in the pathological mechanism of BA. AST can improve lung function, down-regulate the expression of PI3 K and p-AKT proteins in lung tissues, enhance the expression of PETN protein, and reduce the level of type Ⅱ innate immune cells(ILC2 s) in lung tissues of asthmatic mice. In conclusion, AST may inhibit ILC2 s by down-regulating the PI3 K-AKT pathway to relieve asthmatic airway inflammation and reduce airway hyperresponsiveness.

Exploration on Evaluation System for Traditional Medicine Patent / 世界科学技术-中医药现代化

So far, an evaluation system for the patent value of traditional medicine is in absence. For this reason, an evaluation system had been established in this paper, by taking advantage of unique attributes of traditional medicine. This system consisted of 10 key indexes equipped with the algorithm for the calculation of original value and comparative value. The comparative value of patent was easier to show the value difference among patents. In consideration of strong correlation between the legal value, technical value, and economic value of the patent and be-tween evaluation indexes thereof, three kinds of value were combined together without discrimination for integral e-valuation. Besides, with inclusion of specific indexes in this field, the non-specific indexes related or indexes un-available were excluded. Because there is no personal rating involved, this evaluation system is appropriate for the automatic evaluation of patents of traditional medicine and other fields .

Cell membrane chromatography and its application progress in studies of traditional Chinese medicines / 中国中药杂志

As a novel bioaffinity chromatography technique, cell membrane chromatography (CMC) was first established by Professor He in 1996, with which combined high performance liquid chromatography, cytobiology, and receptor pharmacology. The cell membrane stationary phase (CMSP) consists of porous silica coated with active cell membranes. By immersing silica into a suspension of cell membranes, the whole surface of silica was covered by the cell membranes. In CMC, the interaction of drugs or compounds with the immobilized cell membrane or its receptors is investigated using liquid chromatography. In general, with the aim to provide scientific foundation for further development and application, this paper mainly focuses on the characteristics of the cell membrane stationary phase (CMSP), the CMC analytical system, and its applications in traditional Chinese medicines (TCMs) about CMC. With the development of CMC, the breakthrough progress of it in studying active components of TCMs field is expectant.

Situation of epidemic prevention in the late Qing dynasty in Shanghai / 中西医结合学报

To study the implementation of the epidemic prevention by the authorities of the concession and late Qing dynasty through investigation of the prevention and treatment of pestilence in Shanghai from 1872 to 1911, this paper analyzes the issues concerning municipal administration, inspection and disinfection, food sanitation, vaccination, regulatory legislation and health promotion, etc. The experiences are summarized in the study. The lessons drawn from what the concession authority did to prevent pestilence imply that the implementation of health promotion should be carried out according to the variation of the time, location and population, and that traditional Chinese medicine should be involved in the prevention and treatment of pestilence.

Protective effects of yishen ruanjian power on renal interstitial fribrosis in chronic aristolochic acid induced nephropathy rat model / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the protective effects of Yishen Ruanjian Power (YRP) on renal interstitial fibrosis in rats with chronic aristolochic acid induced nephropathy (CAAN).</p><p><b>METHODS</b>Eighteen male SD rats were divided into 3 groups, 6 in each group. Water solution of Caulis Aristolochia Manshuriensis (CAM) Liquid Extract were given to the mice in the model group by gastrogavage to make CAAN animal model. For those in the TCM group, decocted water solution of YRP was given by gastrogavage after the mice being modeled with the above-mentioned method. Tap water was given by gastrogavage to the mice in the control group. Body weight, 24-hr urinary protein excretion and beta2 microglobulin (beta2-MG), and serum creatinine (r) were determined at the end of the 1st, 4th, 8th, 12th and 16th week. At the end of the 16th week, the rats were sacrificed and the pathological figure of their kidneys were observed by Masson staining. Transforming growth factor-beta1 (TGF-beta1), connective tissue growth factor (CTGF), plasminogen activator inhibitor-1 (PAI-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and type I collagen (Col I ) in kidney tissue were determined by RT-PCR and immunohistochemical method, respectively.</p><p><b>RESULTS</b>At end of the 1st week, urinary protein excretion, urinary beta2-MG and SCr in the model group were significantly increased to the levels higher than those in the control group (P < 0.01 or 0.05). Relative area of interstitial fibrosis was significantly enlarged in the model group at the end of the 16th week (P<0.01), and at the same time, the mRNA and protein expression of TCF-beta1, CTGF, PAI-1, TIMP-1 and Col I in kidney tissue were significant up-regulated (P<0.01). After intervention with YRP, the above-mentioned up-regulated parameters, except 24-hr urinary protein excretion, were all significantly inhibited (P <0.01 or 0.05).</p><p><b>CONCLUSION</b>YRP could inhibit the accumulation of extracellular matrix in renal interstitial tissue, so as to alleviate the renal interstitial fibrosis and improve the renal function.</p>
