    Mu ZHANG;Erqin DAI;Yafang ZHANG;Yajun YU;Xinqiang SONG;

    This paper elaborated the chemical components, biological metabolism, and progress in the field of drug development of green tea polyphenols, mainly in the prevention and treatment of cancer, neurodegenerative diseases, and diabetes. The potential anti-tumor activity of tea polyphenols can be achieved through intervening in various stages of tumor generation, development, and metastasis. However, the development of tea polyphenols as a therapeutic drug still faces many challenges, such as low bioavailability. Nanoparticle-based drug delivery systems have particular advantages over the simple tea polyphenols. Since there are emerging safety issues and potential local drug overdose effects, it is necessary to determine the actual dosage and pharmacological mechanism of the drug after encapsulating the nanoparticles.

    Chao ZENG;Meiyuan LU;Tingting MO;Bing WU;Qingtong LAN;

    [Objectives] To study the anti-inflammatory effects of extracts from different parts of Ficus pumila L. [Methods] Inflammatory models of xylene-induced ear swelling, glacial acetic acid-induced celiac capillary permeability and carrageenan-induced toe swelling were established to evaluate the effects of extracts from different parts of F. pumila L. on inflammation. The inflammatory model of ear swelling in mice with bilateral adrenalectomy induced by xylene was established to determine whether its anti-inflammatory effect depends on hypothalamus-pituitary-adrenal axis(HPAA) system. [Results] Compared with the blank control group, except that there was no statistical significance in the low dose group(P>0.05), the high and middle dose groups of extracts from different parts of F. pumila L. had significant inhibitory effects on xylene-induced ear swelling in mice. The high, middle and low dose groups of F. pumila L. extract could significantly increase the celiac capillary permeability of mice induced by glacial acetic acid, and significantly inhibit the toe swelling induced by carrageenan. Compared with the blank control group, the high and middle dose groups of extracts from different parts of F. pumila L. could significantly inhibit xylene-induced ear swelling and carrageenan-induced toe swelling in bilateral adrenalectomy mice. [Conclusions] The extracts from different parts of F. pumila L. had anti-inflammatory activity, and its anti-inflammatory effect was independent of hypothalamus-pituitary-adrenal axis(HPAA) system.

    [Objectives] To explore the protective effects and mechanism of Yinzhihuang combined with metformin on nonalcoholic fatty liver diseases(NAFLD) based on PPAR-α signaling pathway. [Methods] 54 male SD rats were randomly divided into 2 groups, namely normal group(12 rats) and high-fat feed group(42 rats). After 8 weeks, 2 rats were randomly selected from each group. After pathological examination confirmed the success of the NAFLD model, the high-fat feed group was divided into model group, Yinzhihuang(9 000 mg/kg), metformin group(200 mg/kg), Yinzhihuang combined with metformin group(4 500 mg/kg+100 mg/kg), 10 rats in each group. Except the normal group and the model group, the other groups were given treatment drugs at the same time, one time a day, on the fifth weekend of the experiment, at the last time of administration, fasting but giving water for 16 h, then collected blood and liver tissue. Biochemical method was used to detect AST and ALT in serum and SOD, MDA, GSH-px biochemical indicators in liver tissue; enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of TNF-α, IL-6 and TGF-β in liver tissue; Western blot was used to detect the expression of peroxisome proliferators-activated receptor-α(PPAR-α) protein in rat liver tissue. [Results] Compared with the model group, the serum levels of ALT, AST and MDA in liver tissue of model group rats were significantly increased; the levels of SOD and GSH-px in liver tissue were significantly increased; TNF-α and IL-6 and TGF-β contents in liver tissue were significantly increased. [Conclusions] Both Yinzhihuang and metformin have a therapeutic effect on NAFLD rats, and the effect of combined application of the two is significantly better than the intervention effect of Yinzhihuang or metformin alone, the mechanism is possibly associated with the regulation of PPAR-α signaling pathway.

[Methods] 60 Kunming mice were divided into normal group, model group, control group(bifendate) and TFP low, medium and high dose groups according to random number table method, with 10 mice in each group. On the first day of modeling, mice were injected with 0.2 mL of BCG solution(12.5 mg/mL) through the tail vein, and on the eleventh day, 0.2 mL of LPS(37.5 μg/mL) were injected into the tail vein to prepare a mouse model of immune-mediated liver injury; from the first day of modeling, the normal group and the model group were administered intragastrically with the corresponding volume of distilled water, and the bifendate group and the TFP high, medium, and low dose groups were administered intragastrically with the corresponding doses once a day for 11 d. After the last time administration, fasting but giving water for 16 h, took blood from eyes, then collected the liver tissue. The levels of alanine transaminase(ALT) and aspartate transaminase(AST) in serum were detected by biochemical method; transforming growth factor-β1(TGF-β1), intercellular adhesion molecule-1(ICAM-1), interleukin-6(IL-6) and interleukin-1β(IL-1β) expression levels in liver tissue were detected by enzyme-linked immunosorbent assay(ELISA); phosphorylated protein tyrosine kinase JAK-2(p-JAK2), phosphorylated signal transducer and activator of transcription 3(p-STAT3) protein expression levels were detected by Western Blot method; the degree of liver tissue lesions was detected by HE staining. [Results] Compared with the model group, the levels of ALT and AST in the serum of mice in each dose group of TFP(high dose 600 mg/kg, medium dose 400 mg/kg, and low dose 200 mg/kg) were reduced, and the activities of T-SOD and GSH-Px were increased; the content or expression of β1, ICAM-1, IL-6, IL-1β decreased, and the expression of p-JAK2 and p-STAT3 protein decreased; pathological sections showed that the degree of inflammatory necrosis and the degree of lesions in the liver tissues of each dose group of TFP were reduced by varying degrees. [Conclusions] TFP has a protective effect on BCG+LPS-induced immune-mediated liver injury in mice. The mechanism may be related to regulating the phosphorylation level of JAK2 and inhibiting the inflammatory reaction, thereby regulating the TGF-β1/STAT3 signaling pathway and improving the immune-mediated liver injury.

Novel Coronavirus

  • Discussion on the Selection of ACEI and ARB for the Patients with COVID-19 and Hypertension from ACE2

    Jinfeng CHEN;Zhongyi LEI;Chaofeng LIU;Hong FAN;Peng LEI;Xueping WU;Xiaoyong YU;Yanfen ZHOU;Jiejun HOU;

    With the wide spread of COVID-19, some studies have confirmed that novel coronavirus enters the cell through the binding of spike protein and ACE2 protein, which has the risk of causing the virus to enter the cell to accelerate its transmission. ACEI and ARB are the key drugs for the treatment of hypertension and are widely used in clinic. They are good for ventricular and vascular remodeling in patients with hypertension, coronary heart disease and heart failure. ACEI and ARB drugs may increase the expression of ACE2 in lung tissue and increase the risk of aggravation of the disease. According to the advice of hypertension experts: for mild ordinary COVID-19 patients with hypertension, we can consider discontinuing ACEI and ARB drugs, while for severe COVID-19 patients with hypertension, ACEI and ARB drugs should be stopped immediately.

    [Objectives] This paper aimed to investigate the effect of Tuina combined with sling exercise therapy(SET) and psoas & abdominal training on serum 5-hydroxytryptamine(5-HT) and β-endorphin(β-EP) levels in patients with nonspecific low back pain(NLBP). [Methods] Total 46 patients with NLBP who visited the Tuina Department of the First Affiliated Hospital of Hainan Medical University from August 2019 to May 2020 were randomly and evenly divided into control group and treatment group. On the basis of Tuina therapy, the patients in the control group and treatment group were treated with psoas & abdominal training and SET, respectively. After the treatment, the serum 5-HT and β-EP levels of the patients were detected. [Results] The serum 5-HT and β-EP levels in the treatment group were significantly improved compared with the control group(P<0.05). [Conclusions] The nerve & muscle reconstruction techniques of Tuina combined with SET or psoas & abdominal training can improve serum 5-HT and β-EP levels in patients with NLBP.
