Synergetic response on herbal and probiotic applications: a review.

Herbs and their by-products are important traditional medicines and food supplements; they provide numerous beneficial effects for animals. Consequently, probiotics are living cell organisms, nontoxic, and friendly microbes. Probiotics have numerous beneficial activities such as inhibition of pathogens, enhancement of the immune system, growth, disease resistance, improving water quality, reducing toxic effects, synthesis of vitamins, prevention of cancer, reduction of irritable bowel syndrome, and more positive responses in animals. Herbal and probiotic combinations have more active responses and produce new substances to enhance beneficial responses in animals. Herbal and probiotic mixture report is still limited applications for animals. However, the mechanisms by which they interact with the immune system and gut microbiota in animals are largely unclear. This review provides some information on the effect of herbal and probiotic blend on animals. This review discusses current research advancements to fulfill research gaps and promote effective and healthy animal production.

Synergistic interaction of nanoparticles and probiotic delivery: A review.

Nanotechnology is an expanding and new technology that prompts production with nanoparticle-based (1-100 nm) organic and inorganic materials. Such a tool has an imperative function in different sectors like bioengineering, pharmaceuticals, electronics, energy, nuclear energy, and fuel, and its applications are helpful for human, animal, plant, and environmental health. In exacting, the nanoparticles are synthesized by top-down and bottom-up approaches through different techniques such as chemical, physical, and biological progress. The characterization is vital and the confirmation of nanoparticle traits is done by various instrumentation analyses like UV-Vis spectrophotometry (UV-Vis), Fourier transform infrared spectroscopy, scanning electron microscope, transmission electron microscopy, X-ray diffraction, atomic force microscopy, annular dark-field imaging, and intracranial pressure. In addition, probiotics are friendly microbes which while administered in sufficient quantity confer health advantages to the host. Characterization investigation is much more significant to the identification of good probiotics. Similarly, haemolytic activity, acid and bile salt tolerance, autoaggregation, antimicrobial compound production, inhibition of pathogens, enhance the immune system, and more health-beneficial effects on the host. The synergistic effects of nanoparticles and probiotics combined delivery applications are still limited to food, feed, and biomedical applications. However, the mechanisms by which they interact with the immune system and gut microbiota in humans and animals are largely unclear. This review discusses current research advancements to fulfil research gaps and promote the successful improvement of human and animal health.

Comparative Effect of Chemical and Green Zinc Nanoparticles on the Growth, Hematology, Serum Biochemical, Antioxidant Parameters, and Immunity in Serum and Mucus of Goldfish, Carassius auratus (Linnaeus, 1758).

Recently, nano feed supplement research has great attention to improving healthy aquatic production and improving the aquatic environment. With the aims of the present study, chemical and green synthesized nanoparticles are characterized by various instrumentation analyses, namely UV-Vis spectrophotometry (UV-Vis), X-ray diffraction (XRD), Fourier transform infra-red (FTIR) spectroscopy, and scanning electron microscope (SEM). After characterization analysis of these nanoparticles utilized in aquatic animals, the composition ratio is as follows: controls (without ZnO-NPs (0 mg/L)), T1 (0.9 mg/L ZnO-NPs), T2 (1.9 mg/L ZnO-NPs), T3 (0.9 mg/L GZnO-NPs), T4 (1.9 mg/L GZnO-NPs). SEM investigation report demonstrates that the structure of the surface of green synthesized zinc oxide nanoparticles (GZnO-NPs) was conical shape and the size ranging was from 60 to 70 nm. Concerning hematological parameters, the quantity of hemoglobin increased in different doses of green zinc nanoparticles, but the values of MCV and MCH decreased somewhat. However, this decrease was the highest in the T2 group. Total protein and albumin decreased in T2 and triglyceride, cholesterol, glucose, cortisol, creatinine, and urea increased, while in T3 and T4 groups, changes in biochemical parameters were evaluated as positive. Mucosal and serum immunological parameters in the T2 group showed a significant decrease compared to other groups. In zinc nanoparticles, with increasing dose, oxidative damage is aggravated, so in the T2 group, a decrease in antioxidant enzymes and an increase in MDA were seen compared to other groups. In this regard, the concentration of liver enzymes AST and ALT increased in the T2 group compared with control and other groups. This can confirm liver damage in this dose compared with control and other groups. This research work suggests that green synthesized form of zinc nanoparticles in higher doses have less toxic effects in comparison to the chemical form of zinc nanoparticles and can act as suitable nutrient supplements in aquatic animals.

Protective effect of breviscapine against brain injury induced by intrauterine inflammation in preterm rats and its mechanism / 中国当代儿科杂志

OBJECTIVES@#To study the protective effect of breviscapine against brain injury induced by intrauterine inflammation in preterm rats and its mechanism.@*METHODS@#A preterm rat model of brain injury caused by intrauterine inflammation was prepared by intraperitoneal injections of lipopolysaccharide in pregnant rats. The pregnant rats and preterm rats were respectively randomly divided into 5 groups: control, model, low-dose breviscapine (45 mg/kg), high-dose breviscapine (90 mg/kg), and high-dose breviscapine (90 mg/kg)+ML385 [a nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor, 30 mg/kg] (n=10 each). The number and body weight of the live offspring rats were measured for each group. Hematoxylin-eosin staining was used to observe the pathological morphology of the uterus and placenta of pregnant rats and the pathological morphology of the brain tissue of offspring rats. Immunofluorescent staining was used to measure the co-expression of ionized calcium binding adaptor molecule-1 (IBA-1) and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) in the cerebral cortex of offspring rats. ELISA was used to measure the levels of interleukin-6 (IL-6), interleukin-8 (IL-8), and interleukin-1β (IL-1β) in the brain tissue of offspring rats. Western blotting was used to measure the expression of Nrf2 pathway-related proteins in the brain tissue of offspring rats.@*RESULTS@#Pathological injury was found in the uterus, and placenta tissue of the pregnant rats and the brain tissue of the offspring rats, and severe microglia pyroptosis occurred in the cerebral cortex of the offspring rats in the model group. Compared with the control group, the model group had significant reductions in the number and body weight of the live offspring rats and the protein expression levels of Nrf2 and heme oxygenase-1 (HO-1) in the brain tissue of the offspring rats (P<0.05), but significant increases in the relative fluorescence intensity of the co-expression of IBA-1 and NLRP3, the levels of the inflammatory factors IL-6, IL-8, and IL-1β, and the protein expression levels of NLRP3 and caspase-1 in the brain tissue of the offspring rats (P<0.05). Compared with the model group, the breviscapine administration groups showed alleviated pathological injury of the uterus and placenta tissue of the pregnant rats and the brain tissue of the offspring rats, significant increases in the number and body weight of the live offspring rats and the protein expression levels of Nrf2 and HO-1 in the brain tissue of the offspring rats (P<0.05), and significant reductions in the relative fluorescence intensity of the co-expression of IBA-1 and NLRP3, the levels of the inflammatory factors IL-6, IL-8, and IL-1β, and the protein expression levels of NLRP3 and caspase-1 in the brain tissue of the offspring rats (P<0.05). The high-dose breviscapine group had a significantly better effect than the low-dose breviscapine (P<0.05). ML385 significantly inhibited the intervention effect of high-dose breviscapine (P<0.05).@*CONCLUSIONS@#Breviscapine can inhibit inflammatory response in brain tissue of preterm rats caused by intrauterine inflammation by activating the Nrf2 pathway, and it can also inhibit microglial pyroptosis and alleviate brain injury.

Total Glucosides of Paeony Regulate Immune Imbalance Mediated by Dermal Mesenchymal Stem Cells in Psoriasis Mice / 中国结合医学杂志

OBJECTIVE@#To investigate the therapeutic effects of total glucosides of paeony (TGP) on psoriasis based on the immunomodulatory effect of dermal mesenchymal stem cells (DMSCs).@*METHODS@#A total of 30 male BALB/c mice were divided into 6 groups (n=5 in each) by a random number table method, including control, psoriasis model (model, 5% imiquimod cream 42 mg/d), low-, medium- and high-dose TGP (50, 100, and 200 mg/kg, L, M-, and H-TGP, respectively), and positive control group (2.5 mg/kg acitretin). After 14 days of continuous administration, the skin's histopathological changes, apoptosis, secretion of inflammatory cytokines, and proportion of regulatory T cells (Treg) and T helper cell 17 (Th17) were evaluated using hematoxylin-eosin (HE) staining, TdT-mediated dUTP nick end labeling staining, enzyme-linked immunosorbent assay, and flow cytometry, respectively. DMSCs were further isolated from the skin tissues of normal and psoriatic mice, and the cell morphology, phenotype, and cycle were observed. Furthermore, TGP was used to treat psoriatic DMSCs to analyze the effects on the DMSCs immune regulation.@*RESULTS@#TGP alleviated skin pathological injury, reduced epidermis layer thickness, inhibited apoptosis, and regulated the secretion of inflammatory cytokines and the proportion of Treg and Th17 in the skin tissues of psoriatic mice (P<0.05 or P<0.01). There was no significant difference in cell morphology and phenotype between control and psoriatic DMSCs (P>0.05), however, more psoriatic DMSCs remained in G0/G1 phase compared with the normal DMSCs (P<0.01). TGP treatment of psoriatic DMSCs significantly increased cell viability, decreased apoptosis, relieved inflammatory response, and inhibited the expression of toll-like receptor 4 and P65 (P<0.05 or P<0.01).@*CONCLUSION@#TGP may exert a good therapeutic effect on psoriasis by regulating the immune imbalance of DMSCs.

Relationship between Dining Place, Iodine Source, and Iodine Nutrition in School-Age Children: A Cross-Sectional Study in China / 生物医学与环境科学（英文）

OBJECTIVE@#This study assesses the impact of iodine-rich processed foods and dining places on the iodine nutritional status of children.@*METHODS@#School-aged children (SAC) in seven provinces in China were selected by school-based multi-stage sampling. Urinary iodine, salt iodine, and thyroid volume (TVOL) were determined. Questionnaires were used to investigate dining places and iodine-rich processed foods. The water iodine was from the 2017 national survey. Multi-factor regression analysis was used to find correlations between variables.@*RESULTS@#Children ate 78.7% of their meals at home, 15.1% at school canteens, and 6.1% at other places. The percentage of daily iodine intake from water, iodized salt, iodine-rich processed foods, and cooked food were 1.0%, 79.2%, 1.5%, and 18.4%, respectively. The salt iodine was correlated with the urinary iodine and TVOL, respectively (r = 0.999 and -0.997, P < 0.05). The iodine intake in processed foods was weakly correlated with the TVOL (r = 0.080, P < 0.01). Non-iodized salt used in processed foods or diets when eating out had less effect on children's iodine nutrition status.@*CONCLUSION@#Iodized salt remains the primary source of daily iodine intake of SAC, and processed food has less effect on iodine nutrition. Therefore, for children, iodized salt should be a compulsory supplement in their routine diet.

Preventive and reparative functions of host-associated probiotics against soybean meal induced growth, immune suppression and gut injury in Japanese seabass (Lateolabraxjaponicus).

A 56-day feeding trial was conducted to examine the preventive and reparative functions of host-associated probiotics against high soybean meal (SM)-induced negative effects in Japanese seabass (Lateolabrax japonicus). Fish continuously fed low SM (containing 16% SM) and high SM (containing 40% SM) diets were named as positive (PC) and negative (C) control, respectively. Preventive functions of probiotics were evaluated by continuously feeding diets LF3 (Lactococcus petauri LF3 supplemented in high SM diet, group PLF3) and LF4 (Bacillus siamensis LF4 supplemented in high SM diet, group PLF4), while reparative functions were estimated by feeding the high SM diet during 0-28 days, then feeding diets LF3 (group RLF3) and LF4 (group RLF4) until day 56. Compared with the group PC, suppressed growth and immunity, and damaged intestinal health were observed in the group C on days 28 and 56. Fish in groups PLF3 and PLF4, rather than in groups RLF3 and RLF4, showed higher growth compared with the group C and displayed similar immune status to the group PC, indicating that the initial and continued application of probiotic LF3 and LF4 can efficiently improve high SM induced growth and immune deficiency in Japanese seabass, but probiotics had limited reparative benefits when they were administrated at the middle of the feeding trial (28 d). Furthermore, probiotics showed good preventive functions and limited reparative functions on gut health via improving intestinal morphology and inflammation markers, for example, decreasing diamine oxidase activity and d-lactate content, while up-regulating anti-inflammatory TGF-ß1 expression and down-regulating pro-inflammatory TNF-α, IL-1ß, and IL-8 expressions. Moreover, dietary supplementation of probiotics (especially on day 56) could effectively shape the gut microbiota, such as significantly decreasing abundances of opportunistic pathogens (phylum Actinobacteria, genera Pseudomonas and Moheibacter on day 28, phylum Proteobacteria, genus Plesiomonas on day 56), significantly increasing gut microbial diversity and abundances of possible beneficial bacteria (phylum Bacteroidetes and genus Lactobacillus on day 28, phyla Firmicutes, Bacteroidetes and Cyanobacteria, genera Bacillus, Lactobacillus and Bacteroides on day 56). In conclusion, we evidenced for the first time that host-associated L. petauri LF3 and B. siamensis LF4 can provide effectively preventive and certain reparative functions against high SM-induced adverse effects in L. japonicus.

[Screening of differentially expressed genes for colorectal cancer and prediction of potential traditional Chinese medicine: based on bioinformatics].

This study screened and analyzed the differentially expressed genes(DEGs) between colorectal cancer(CRC) tissues and normal tissues with bioinformatics techniques to predict biomarkers and Chinese medicinals for the diagnosis and treatment of CRC. The microarray data sets GSE21815, GSE106582, and GSE41657 were downloaded from the Gene Expression Omnibus(GEO), and the DEGs were screened by GEO2 R, followed by the Gene Ontology(GO) tern enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis of the DEGs based on DAVID. The protein-protein interaction network was constructed by STRING, and MCODE and Cytohubba plug-ins were used to screen the significant modules and hub genes in the network. UCSC, cBioPortal, and Oncomine were employed for hierarchical clustering, survival analysis, Oncomine analysis, and correlation analysis of clinical data. Coremine Medical was applied to predict the Chinese medicinals acting on hub genes. A total of 284 DEGs were screened out, with 146 up-regulated and 138 down-regulated. The up-regulated genes were mainly involved in cell cycle, NLRs pathway, and TNF signaling pathway, and the down-regulated genes were related to mineral absorption, nitrogen metabolism, and bicarbonate reabsorption in proximal tubules. The 15 hub genes were CDK1, CDC20, AURKA, MELK, TOP2 A, PTTG1, BUB1, CDCA5, CDC45, TPX2, NEK2, CEP55, CENPN, TRIP13, and GINS2, among which CDK1 and CDC20 were regarded as core genes. The high expression of CDK1 and CDC20 suggested poor prognosis, and they significantly expressed in many cancers, especially breast cancer, lung cancer, and CRC. The expression of CDK1 and CDC20 was correlated with gender, tumor type, TNM stage, and KRAS gene mutation. The potential effective medicinals against CRC were Scutellariae Radix, Scutellariae Barbatae Herba, Arnebiae Radix, etc. The significant expression of CDK1 and CDC20 can help distinguish tumor tissues from normal tissues, and is related to survival prognosis. Thus, the two can be used as biomarkers for the diagnosis and treatment of CRC. This study provides a reference for related drug development.

Pathogenesis of Gouty Arthritis and Intervention with Chinese Medicines： A Review / 中国实验方剂学杂志

Gouty arthritis （GA） is the metabolic rheumatism caused by purine metabolism disorder， which can be acute or chronic. The main manifestations of GA include recurrent redness， swelling， heat pain， and dysfunction of the affected joints. According to the theory of modern medicine， GA is closely associated with the increase in uric acid， the participation of inflammatory cytokines， the weakening of antioxidant response， apoptosis， and the imbalance of intestinal flora and bone metabolism， whereas the specific pathogenesis remains unclear. GA is characterized by easy diagnosis， difficult treatment， and high recurrence rate， which seriously affects the life quality of patients. Colchicine， corticosteroids， non-steroidal anti-inflammatory drugs， and selective cyclooxygenase-2 inhibitors are the commonly used western medicines for this disease， which demonstrate remarkable short-term therapeutic effect. However， long-term use of these medicines will bring serious adverse reactions. Chinese medicines， with high safety and causing few adverse reactions， have a variety of active components which can act on multiple pathways and targets to exert synergistic effects， thus attracting wide attention. This paper systematically reviews the literature reporting the Chinese medicines in improving antioxidant response， reducing chondrocyte apoptosis， and regulating intestinal flora and bone metabolism， aiming to further clarify the pathogenesis of GA and provide a scientific basis for the clinical application of Chinese medicines in the prevention and treatment of GA.

Metabonomics and its application in Chinese medicine processing / 中国中药杂志

Chinese medicine processing is a procedure to process medicinal materials under the guidance of traditional Chinese medicine(TCM) theories by using unique methods in China. The medicinal materials can only be used clinically after proper processing. With the development of the modernization of TCM, it is difficult to solve the problems in the inheritance, development, and internationalization of Chinese medicine processing. Metabonomics, a new omics technology developed at the end of the last century, is used to infer the physiological or pathological conditions of the organism with the methods such as NMR and LC-MS via investigating the changes in endogenous small molecule metabolic network after the organism is stimulated by external environment. Metabonomics coincides with the holistic view of TCM because it displays the characteristics of integrity, comprehensiveness, and dynamics, and it has been widely applied in the field of Chinese medicine processing in recent years. This study summarized the application of metabonomics in the processing mechanism and quality control of Chinese medicine processing and prospected the development of this technology in the field of Chinese medicine processing.

Strategy of nutrition intervention on Duchenne muscular dystrophy / 中华临床营养杂志

Duchenne muscular dystrophy (DMD) is a fatal X-linked genetic disease caused by complete absence of Dystrophin due to mutation of DMD gene. Typical symptoms are progressive muscle loss which cause slow walking, gait abnormalities, falls, and difficult squatting. The adult patients often died from the respiratory and cardiovasucula failure in their early life stage.The early introduction of steroids has altered the natural history of the disease, but can exacerbate weight gain in a population already susceptible to obesity. Prior to commencing steroids, anticipatory guidance for weight management should be provided. Malnutrition is a feature of end stage disease requiring a multidisciplinary approach, such as texture modification and supplemental feeding. Micronutri- ent requirements are yet to be determined but, as a result of corticosteroid treatment, vitamin D and calcium should be supplemented. The multidisciplinary management of boys with DMD including nutrition treatment has progressed significantly and improved the life qulity of both patients and their parents.

Molecular Mechanism of Modified Guizhi Fulingwan Intervention on Uterine Fibroids in Rats Based on micRNA Expression Profiling / 中国实验方剂学杂志

Objective:To explore the molecular mechanism of modified Guizhi Fulingwan in rats with uterine fibroids. Method:Seventy-two female adult SD rats of SPF grade were randomly divided into a model group， a normal group， and a preventive administration group. The model group and preventive administration group were established by estrogen and progestin loading method. After successful modeling， the rats in the model group were randomly divided into a western medicine group （mifepristone）， the high-dose traditional Chinese medicine（TCM） group， and a low-dose TCM group. All the rats were dosing as required once a day for 28 consecutive days. Hematoxylin-eosin（HE）staining was used to observe the morphological changes of the uterus. The micRNA gene chip was used to detect the expression profile of uterine micRNA gene. Differential expressions of micRNA were screened by bioinformatics methods. Gene function enrichment was used to predict the possible signaling pathways in rats with uterine fibroids by modified Guizhi Fulingwan. Result:Compared with the normal group， microRNA of the model group was 1 up-regulated and 9 down-regulated. Compared with the model group， microRNA of the high-dose group of TCM group was 2 up-regulated and 1 down-regulated， in the preventive administration group， 9 was up-regulated and 2 was down-regulated. Gene function enrichment analysis indicated that four signaling pathways were closely related to uterine fibroids. They were mitogen-activated protein kinase （MAPK） signaling pathway， Wnt signaling pathway， mammalian rapamycin target protein （mTOR） signaling pathway and vascular endothelial cell growth factor （VEGF） signaling pathway. Conclusion:Modified Guizhi Fulingwan affected the expression profile of micRNA in rat model of uterine fibroids induced by estrogen and progesterone， suggesting that modified Guizhi Fulingwan may involve in a variety of biological processes such as signal transduction and gene regulation in the treatment of uterine fibroids.

Research Progress on G2/M Arrest in Breast Cancer Cells by Active Compounds of Traditional Chinese Medicine / 中国实验方剂学杂志

The global incidence of breast cancer has increased year by year. Breast cancer has the highest mortality rate in female patients with malignant tumors. Traditional Chinese medicine（TCM） has made great contribution to health of human being， improving the overall curative effect， reducing the patients' pain， improving the quality of life and alleviating adverse reactions in patients. TCM and its active compounds can inhibit the proliferation of breast cancer cells by inducing cell cycle arrest， invasion， metastasis and reversing multidrug resistance. The effect of the compounds in TCM is obvious on inducing the arrest of the breast cancer cells cycle. It′s a novel method to fight against breast cancer by influencing the progress of the breast cancer cell cycle and inducing the cell cycle arrest in breast cancer cells. Lots of studies have shown that the G2/M phase checkpoint which transition from gap-phase （G2 phase） to mitotic phase （M phase） in the cell cycle is the key point for cell survival or death. Many antitumor drugs can inhibit the proliferation of tumor cells through the cell cycle arrest. We summarized the domestic and foreign literatures in recent years， and comprehensively explained the research progress on the related regulatory molecules in G2/M arrest. In addition， we summarized and sorted out the researches on the methods and ways of alkaloids， polysaccharides， terpenes， flavonoids， saponins and other active compounds of TCM in inducing the G2/M arrest of human breast cancer cells. By summarizing the active compounds of various Chinese medicines in inducing G2/M arrest of breast cancer cells， and reviewing the research progress on mechanism of active TCM compounds for inhibiting the proliferation of breast cancer cells， we will， in this paper， investigate the mechanism of active TCM compounds for inhibiting the proliferation of breast cancer cells through inducing G2/M arrest of human breast cancer cells， so as to provide a scientific basis for in-depth research on the anti-breast cancer mechanism of the active compounds in TCM.

The identification of species primordium has been one of the hot issues in the identification of traditional Chinese medicine. Sea snake is one of the most valuable Chinese medicinal materials in China. In order to understand the origin and varieties of sea snake in the market, we studied the molecular identification of 46 sea snakes by cytochrome B(Cytb). After comparison and manual correction, the sequence length was 582 bp, and the content of A+T(58.9%) was higher than that of G+C(41.1%). There exist 197 variable sites and 179 parsimony-informative sites of the sequence. There are 44 kinds of sequence alignment with consistency equal to 100%, and 2 kinds equal to 96%. A total of 408 Cytb effective sequences were downloaded from GenBank database, with a total of 68 species. Phylogenetic tree of a total of 454 sea snake sequences with the samples in this study were constructed by neighbor-joining trees and Bayesian inference method, respectively, which can identify 42 samples of medicinal materials, while 4 samples can not be identified because of their low node support. The results showed that the species of the sea snake medicine were at least from 2 genera and 5 species, namely, Aipysurus eydouxii, Hydrophis curtus, H. caerulescen, H. curtus, H. ornatus and H. spiralis. This study suggested that the original species of commercial sea snake are very complex and can provide insight into the identification of sea snakes.

Mechanism of Astragali Radix-Coptis Rhizoma pair in treating type 2 diabetes mellitus based on network pharmacology / 中国中药杂志

This study aims to explore the main mechanism of Astragali Radix-Coptis Rhizoma pair(hereinafter referred to as the pair) in the treatment of type 2 diabetes mellitus(T2 DM) based on network pharmacology and animal experiment. The main Chinese medicine compound prescriptions for T2 DM were retrieved from CNKI database and the medicinals with high frequency among these prescriptions were screened. The active components in the above medicinals were searched from TCMSP, TCMID, and previous research, targets of the components from SwissTargetPrediction and SEA, and targets for the treatment of T2 DM from DISGENET, TTD, and DrugBank. Thereby, the medicinal-component-disease-target network was constructed with Cytoscape. The targets were input in String database to yield the related proteins and the protein-protein interaction(PPI) network was constructed by Cytoscape. The biological functions of proteins in the PPI network were analyzed by Cluego. Then, high-fat high-sugar diet and 30 mg·kg~(-1) streptozotocin(STZ, intraperitoneal injection, once) were employed to induce T2 DM in rats and the T2 DM rats were classified into the control group, model group, positive drug(metformin) group, and pair group. After one month of administration, the changes of blood glucose and blood lipids [triglyceride(TG), cholesterol(CHO), low density lipoprotein(LDL), high density lipoprotein(HDL)] were detected with biochemical methods and pathological changes of islet and collagen deposition in pancreatic tissue by HE staining and Masson staining, respectively. The result showed that pair can be used for T2 DM treatment. ras-related C3 botulinum toxin substrate 1(RAC1), paraoxonase 1(PON1), beta-galactoside alpha 2,6-sialyltransferase 1(ST6 GAL1), insulin receptor(INSR), sex hormone-binding globulin(SHBG), ileal sodium/bile acid cotransporter(SLC10 A2), endothelin-1 receptor A(EDNRA), peroxisome proliferator-activated receptor A(PPARA), endothelin receptor B(EDNRB), and 5-hydroxytryptamine receptor 2 A(HTR2 A) were the targets of the pair for the treatment of T2 DM. The main biological functions of the pair were regulating the metabolism of blood glucose and li-pids and protecting the cardiovascular system. The fasting blood glucose, and serum TG, CHO, and LDL were higher(P<0.01) and the HDL was lower(P<0.05) in the model group than in the control group on the 7 th, 14 th, and 28 th days. The fas-ting blood glucose and the serum TG, CHO, and LDL decreased(P<0.05) and the serum HDL increased(P<0.05) in the metformin group and the pair group as compared with those in the model group on the 14 th and 28 th days. There were no significant differences in blood glucose, TG, CHO, LDL, and HDL between the metformin group and the pair group. Rats in the model group demonstrated damaged structures of islets and pancreas, obviously increased deposition of collagen in islets and pancreas, and blurred cell boundaries. Metformin and the pair significantly alleviated the damaged structures and collagen deposition. The pair can effectively regulate the disorders of blood glucose and lipid metabolism in T2 DM and protect the structure and functions of pancreas and islets by controlling cardiovascular system, which is worthy of clinical application and can be used for drug development.
