ABSTRACT

Two cardenolide glycosides, corotoxigenin 3-O-[β-D-glucopyranosyl-(1→4)-6-deoxy-β-D-glucopyranoside] (1) and coroglaucigenin 3-O-[β-D-glucopyranosyl-(1→4)-6-deoxy-β-D-glucopyranoside] (2), were isolated from the seed fairs of Asclepias curassavica. The structures of 1-2 were determined based on the combination of the analysis of their MS, NMR spectroscopic data and acid hydrolysis. The inhibitory effects of compounds 1 and 2 on human colorectal carcinoma cells (HCT116), non-small cell lung carcinoma cells (A549) and hepatic cancer cells (SMMC-7721) were evaluated. The results showed that both compounds 1 and 2 significantly inhibited the viability, proliferation, and migration of A549, HCT116 and SMMC-7721 cells, suggesting that compounds 1 and 2 can be applied in the treatment of lung, colon and liver cancers in clinical practice. This study may not only provide a scientific basis for clarifying the active ingredients in A. curassavica, but also help to understand its antitumor activity, which can promote the application of A. curassavica in clinical treatment of various cancers.

ABSTRACT

Network Meta-analysis was used to evaluate the efficacy and safety of different oral Chinese patent medicines combined with transcatheter arterial chemoembolization(TACE) in the treatment of primary liver cancer. Randomized controlled trials of oral Chinese patent medicines for primary liver cancer were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and EMbase databases from inception to May 2020. According to the Cochrane recommendation standard, the quality of the included articles was evaluated, and the data were analyzed by RevMan, R software and GeMTC software. A total of 10 kinds of oral Chinese patent medicines and 68 RCTs were included. Network Meta-analysis results showed that: as compared with TACE alone, 10 kinds of oral Chinese patent medicines combined with TACE showed advantages in effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence. In the pairwise comparison of oral Chinese patent medicines, the results showed that Cidan Capsules were superior to Jinlong Capsules and Xihuang Pills in 1-year survival rate. According to the probabi-lity ranking results: Shenyi Capsules and Ganfule were more obvious in improving the effective rate; Cidan Capsules and Shenyi Capsules were more effective in improving the 1-year survival rate; Pingxiao Capsules and Shenyi Capsules had better efficacy in improving 2-year survival rate; Huaier Granules and Shenyi Capsules had better efficacy in improving the quality of life; Huisheng Oral Liquid and Ganfule were more effective in reducing the incidence of adverse reactions(such as nausea, vomiting and leukocytosis). The current evidence showed that oral Chinese patent medicine combined with TACE was superior to TACE alone in efficacy and safety. In terms of the effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence, the optimal treatment measures were Shenyi Capsules, Cidan Capsules, Pingxiao Capsules, Huaier Granules and Huisheng Oral Liquid in turn. However, due to the limitations of the research, the current level of evidence is not high, and clear conclusions and evi-dence strength still need to be further verified and improved by high-quality researches.

ABSTRACT

To systematically evaluate the efficacy and safety of Huaier Granules in the adjuvant treatment of primary liver cancer. The databases of CNKI, Wanfang, VIP, CBMdisc, PubMed, Cochrane Library and EMbase were searched by computer to screen out the randomized controlled trial on Huaier Granules combined with Western medicine in the treatment of primary liver cancer from the establishment of the databases to January 2020. Data extraction and quality evaluation were conducted for the included literature. Meta-analysis was conducted with RevMan 5.3 software, and evidence quality evaluation was conducted for the outcomes by GRADE profiler software. A total of 24 articles were included, with a total sample size of 2 664 cases. Meta-analysis showed that as compared with Western medicine alone, Huaier Granules combined with Western medicine could improve the objective remission rate(RR=1.38, 95%CI[1.26, 1.51], P<0.000 01), disease control rate(RR=1.29, 95%CI[1.10, 1.52], P=0.002) and 6-month survival rate(RR=1.20, 95%CI[1.10, 1.32], P<0.000 1), 1-year survival rate(RR=1.39, 95%CI[1.23, 1.58], P<0.000 01), 2-year survival rate(RR=1.95, 95%CI[1.28, 2.96], P=0.002), KPS score(MD=17.15, 95%CI[6.47, 27.83], P=0.002) and the improvement rate of KPS score(RR=2.02, 95%CI[1.47, 2.77], P<0.000 1), AFP decline rate(RR=1.40, 95%CI[1.20, 1.62], P<0.000 1), CD3~+(MD=17.34, 95%CI[9.28, 25.40], P<0.000 1), CD4~+(MD=8.62, 95%CI[1.59, 15.64], P=0.02), CD8~+(MD=1.95, 95%CI[-3.93, 7.82], P=0.52), CD4~+/CD8~+(MD=0.42, 95%CI[-0.33, 1.17], P=0.27); reduce the level of AFP(MD=-71.57, 95%CI[-80.42,-62.72], P<0.000 01), recurrence rate(RR=0.76, 95%CI[0.67, 0.85], P<0.000 01), and incidence of adverse reactions(RR=0.60, 95%CI[0.41, 0.89], P=0.01) in patients with primary liver cancer. According to the GRADE system, the evidence for outcome measures was low to very low. The results show that Huaier Granules have certain efficacy and high safety in adjuvant treatment of primary liver cancer, but its effect in reducing adverse reactions and improve immunity remains to be verified. Due to the poor quality of the included studies and evidences, the conclusions still need to be further verified by multi-center, large sample, and randomized double-blind controlled studies.

ABSTRACT

To investigate the hepatoprotective effect of Schisandrae Chinensis Fructus (SCF) on CCl₄-induced liver injury, observe its effect on serum metabolites, explore its scientific connotation in liver preservation and find the biomarkers for hepatoprotective effect of SCF. Liver injury model was established by using CCl₄. The pathological sections of liver tissues were observed and the contents of alanine transaminase (ALT) and aspartate transaminase (AST) in serum were determined. The metabolic skills were adopted based on ultra performance liquid chromatography time-of-flight mass spectrometry (UPLC-Q-TOF-MS), principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) for screening and identification of biomarkers related to liver injury. The results showed the metabolites in blank group, model group and administration group could be easily distinguished, 50 differential compounds were identified and 7 possible metabolic pathways of liver protection were enriched. In this experiment, the hepatoprotective effect of SCF was verified, and the related metabolic pathways such as amino acid metabolism, vitamin metabolism and glycerophospholipid metabolism were discussed.

ABSTRACT

Objective·To investigate the relationship between serum level of caveolin-1 (Cav-1) and early neurological deterioration (END) in patients with acute cerebral infarction. Methods·A total of 126 consecutive patients with acute cerebral infarction were recruited from July 2016 to January 2017 in Department of Neurology, the First Affiliated Hospital of Chongqing Medical University. The serum Cav-1 levels of all patients were detected by enzyme-linked immunosorbent assay (ELISA) test. The neurological deficits were assessed by the National Institutes of Health Stroke Scale (NIHSS) and the Glasgow Coma Scale (GCS) at the same time. Compared with the admission baseline NIHSS score, if second motor NIHSS score increased ≥ 1 point or the total NIHSS score increased ≥ 2 points within 3 days after hospitalization, they were classified as END group, otherwise they were classified as non-END group. Multivariable Logistic regression analysis was used to examine the independent predictors of END in the patients. Receiver operating characteristic (ROC) curves were obtained to explore Cav-1 levels in predicting END. Results·Serum Cav-1 levels in END group were significantly higher than those in non-END group [(29.88±19.57) ng/mL vs (16.08±13.37) ng/mL, P=0.000]. Based on the ROC curves, the best cut-off point of serum Cav-1 for predicting END was 16.55 ng/mL. The sensitivity and specificity were 73.33% and 74.07%, respectively. Multivariable Logistic regression analysis showed that Cav-1≥16.55 ng/mL remained an independent predictor of END (OR=4.936, 95%CI 1.608-15.155, P=0.005). Conclusion·Serum Cav-1 is an independent predictor of END in patients with acute cerebral infarction.

ABSTRACT

OBJECTIVE: To prepare and evaluate resveratrol-loaded mesoporous silica nanoparticles modified by amino (NH2-MSN-RES) to improve the bioavailability of resveratrol. METHODS: Mesoporous silica nanoparticles modified by amino (NH2-MSN) were synthesized by the modified Stober method. The structure of the nanoparticles were analyzed and characterized by FT-IR, Malvern particle size analyzer, and TEM. By introducing the innovative preparation process of repeated saturated solution adsorbing method, RES was encapsulated into NH2-MSN in larger amount. Dialysis bag method was used to investigate the in vitro drug release characteristics and MTT method was used to investigate the cytotoxicity on Caco-2 cells. The transport ability of the carrier was investigated by the Caco-2 cells monolayer model. Finally, the pharmacokinetics of NH2-MSN-RES was studied in rats. RESULTS: The particle size distribution of NH2-MSN was uniform with an average value of (98.4±2.8) nm, and the Zeta potential was (13.2±1.8) mv. Within the scope of 0-20 μg·mL-1, NH2-MSN had no obvious toxicity on Caco-2 cells. After 8 times of repeated adsorption, the drug loading of NH2-MSN-RES reached up to (19.26±2.51)%. In the drug release experiment, the cumulative release quantity of NH2-MSN-RES was 73.3% within 48 h, indicating sustained-release characteristics. NH2-MSN-RES had good ability of transmembrane transport in the Caco-2 cell monolayer model, and the two-way apparent permeability coefficient (Papp) was much larger than the RES solution. In the pharmacokinetic study, RES solution complied with one-compartment model, whereas NH2-MSN-RES complied with two-compartment model, indicating that the carrier changed the pharmacokinetic characteristics of RES. The AUC0-∞ of NH2-MSN-RES was 2.58-fold of that of RES solution, what's more, the t1/2, tmax, and ρmax of NH2-MSN-RES were significantly greater than those of RES solution. CONCLUSION: NH2-MSN is synthesized by modified Stober method successfully. Repeated saturated solution adsorbing method could effectively improve the drug loading. NH2-MSN-RES improves the bioavailability of RES prominently. NH2-MSN will be a promising nano-material for oral drug delivery carrier.
