Clinical efficacy of Matrine and Sodium Chloride Injection in treatment of 40 cases of COVID-19 / 中国中药杂志

In this paper, we analyzed medical records of 40 patients with coronavirus disease 2019(COVID-19), in order to explore the clinical efficacy of Matrine and Sodium Chloride Injection in the treatment of COVID-19. The investigation was based on the results of a previous animal test, which was aimed to investigate and confirme the clinical efficacy of Matrine and Sodium Chloride Injection in the treatment of COVID-19. The animal test demonstrated that Matrine and Sodium Chloride Injection has a significant therapeutic effect on the human coronavirus pneumonia for the model mice. The lung inhibition index reached up to 86.86%. The evaluation was conducted on 40 confirmed cases of COVID-19 treated at Jingzhou Hospital of Infectious Disease(Chest Hospital) of Hubei Pro-vince from January 30~(th) to March 21~(th), 2020. In these cases, patients were treated with other integrated Chinese and Western medicines regimens in the recommended Matrine and Sodium Chloride Injection diagnosis and treatment regimen. The clinical manifestations, laboratory data, nucleic acid clearance time, and imaging data were compared and analyzed before and after treatment. After administration with Matrine and Sodium Chloride Injection, the clinical symptoms of 40 cases were alleviated markedly, and their blood analysis and biochemical indexes returned to normal. The lung CT showed more than 50% of lesion absorption rate, and the viral nucleic acid test showed the average clearance time of patients was 16.6 days, and the average length of hospital stay was 25.9 days. After administration with Matrine and Sodium Chloride Injection, the symptoms of cough and fatigue were alleviated significantly, and the appetite was significantly improved compared with before, especially for patients with gastrointestinal symptoms. Additionally, laboratory indicators, especially absolute value and ratio of lymphocytes and CRP were significantly alleviated. According to the chest CT for short-term review, the absorption of lung lesions was faster than before, especially for grid-like and fibrotic lesions. Compared with antiviral drugs, such as Abidol and Kriging, the nucleic acid clearance time was significantly shorter than the cases treated with Matrine and Sodium Chloride Injection. The clinical effective rate of 40 cases was 100.0%. We believed that Matrine and Sodium Chloride Injection have a good clinical effect in the treatment of COVID-19, and suggested increasing the clinical application and further conducting large-sample-size cli-nical verification.

Effect of Rhizoma coptidis and Radix rehmanniae with different ratio on pharmacokinetics of berberine in rats / 中国中药杂志

<p><b>OBJECTIVE</b>To study the effect of Rhizoma Coptidis and Radix Rehmanniae with the different ratio on the pharmacokinetics of berberine in rats.</p><p><b>METHOD</b>24 rats were grouped to 4 groups randomly. Decoction, in which the proportion of Rhizoma Coptidis to Radix Rehmanniae is 1:0, 1:1, 1:4, 1:8 differently, was intragastrically given to the 4 groups. HPLC was used to determine concentration of berberine in serum. We adopted DAS 2.0 to analysis pharmacokinetic parameters of berberine.</p><p><b>RESULT</b>The concentration-time curves was all fitted to two-compartment model with a weight of 1/C2. Difference of 4groups in C(max), AUC(0-t), AUC(0-infinity), is significant (P <0.05).</p><p><b>CONCLUSION</b>Radix Rehmanniae of large dose can effectively enhance berberine's bioavailability in rats.</p>

Effects of Jiantaiye on estrogen receptor and mRNA expressions in uterus of mice with embryo implantation dysfunction / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the effect of Jiantaiye (JTY) on the expression of estrogen receptor (ER) and ER mRNA in uterus of mice with embryo implantation dysfunction.</p><p><b>METHODS</b>Embryo implantation dysfunction mouse models were induced with mifepristone and treated with JTY. All animals were sacrificed on day 8 of pregnancy. The endometrial ER and ER mRNA expressions were assessed by immunnohistochemical SP method and semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>Area ratio and absorbency of ER in the JTY treated group's gland and stroma were higher than those of the model group, quite similar to those of the normal control's, and ER mRNA expression in treated group's uterus was significantly higher than that in the models, but it was not significantly different from the normal control.</p><p><b>CONCLUSION</b>JTY improves the endometrial development by increasing ER and ER mRNA expressions of uterus of mice with embryo implantation dysfunction.</p>

Effects of jiantai liquid on the expression of estrogen/progesterone receptors in embryo implantation dysfunction mice endometrium / 中国中药杂志

<p><b>OBJECTIVE</b>To explore the mechanism of Jiantai liquid on the endometrium development of embryo implantation dysfunction mice.</p><p><b>METHOD</b>The model of embryo implantation dysfunction mice was induced by mifepristone and treated by Jiantai liquid. All animals were sacrificed on day 8 of pregnancy. Estradiol and progesterone concentrations in serum and endometrium tissue homogenates were measured by radioimmunoassay method, the endometial expressions of estrogen receptor (ER)and progesterone receptor (PR)assessed by immunohistochemical SP method.</p><p><b>RESULT</b>There were no significantly differences in the estradiol and progesterone concentrations in serum and uterus tissue homogenates among three groups( P > 0.05). Absorbency and area rate of ER, PR in model group' s gland and stroma were higher than those in model group(P < 0.05), which was similar with the control group( P > 0.05).</p><p><b>CONCLUSION</b>Jiantai liquid increase the implantation rate and improve the endometrial development by increasing the expressions of ER, PR in endometrium of embryo implantation dysfunction</p>

Effect of jiantai liquid on expression of estrogen and progesterone receptors in uterus of mice with embryo implantation dysfunction induced by mifepristone / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the molecular mechanism of jiantai liquid (JTL) in improving endometrial receptivity of mice with embryo implantation dysfunction (EID).</p><p><b>METHODS</b>Mice model of EID induced by mifepristone were intervened with JTL (Twig of Chinese Taxillus, Red Sage root, Chinese Angelica, Milkvetch root, Chuanxiong rhizome), and sacrificed on day 8 of pregnancy. The endometrial estrogen receptor (ER) and progesterone receptor (PR) protein and their gene expressions were assessed by Western blot and semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>Levels of ER and PR protein and their gene expressions in the JTL treated group were significantly higher than those in the model group respectively (all P < 0.05), and showed insignificant difference from those in the normal control group (all P > 0.05).</p><p><b>CONCLUSION</b>JTL could promote the development of endometrium and improve the embryo implantation by way of regulating the levels of ER and PR protein and gene expression in mice with EID.</p>
