ABSTRACT

OBJECTIVE: To investigate the mechanism by which Sini decoction (, SND) improves renal fibrosis (Rf) in rats based on transforming growth factor ß1/Smad (TGF-ß1/Smad) signaling pathway. METHODS: Network pharmacology was applied to obtain potentially involved signaling pathways in SND's improving effects on Rf. The targets of SND drug components and the targets of Rf were obtained by searching databases, such as the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCSMP) and GeenCard. The intersection targets of two searches were obtained and underwent signaling pathway analysis using a Venn diagram. Then experimental pharmacology was utilized to prove and investigate the effects of SND on target proteins in the TGF-ß1/Smad signaling pathway. The Rf rat model was established by unilateral ureteral occlusion (UUO). The expression levels of transforming growth factor, matrix metalloproteinase-9 (MMP-9), matrix metal protease-2 (MMP-2), connective tissue growth factor (CTGF), and tissue inhibitor of metalloproteinase-1 (TIMP-1) were determined by Masson staining of rat renal tissue, and immunohistochemical methods. The expression levels of Smad3, Smad2, and Smad7 in renal tissue were determined by Western blotting (WB). The mechanism of the improving effects of SND on Rf was investigated based on TGF-ß1/Smad signaling pathway. RESULTS: A total of 12 drug components of Fuzi (Radix Aconiti Lateralis Preparata), 5 drug components of Ganjiang (Rhizoma Zingiber), and 9 drug components of Gancao (Radix Glycy et Rhizoma) were obtained from the database search, and 207 shared targets were found. A total of 1063 Rf targets were found in the database search. According to the Venn diagram, in total, 96 intersection targets were found in two database searches. The metabolic pathways involved included TGF-ß signaling pathway, phosphatidylinositol-3-kinase/serine-threonine protein kinase signaling (PI3K/Akt) pathway, and hypoxia-inducible factor-1 (HIF-1) signaling pathway. Masson staining analysis showed that compared with the model group, the renal interstitial collagen deposition levels in the SSN and SND groups were significantly lower (P < 0.05). Immunohistochemical analysis, compared with the control group, the positive cell area expression levels of MMP-9/TIMP-1 and MMP-2/TIMP-1 in the kidney tissue of the model group were significantly decreased (P < 0.05, P < 0.01), and the positive cell area expression levels of CTGF and TGF-ß1 were significantly increased (P < 0.01). Compared with the model group, the positive cell area expression levels of MMP-9/TIMP-1 and MMP-2/TIMP-1 in the kidney tissue of the SSN and SND groups were significantly increased (P < 0.05, P < 0.01), and the positive cell area expression levels of CTGF and TGF-ß1 in the kidney tissue were significantly decreased (P < 0.05, P < 0.01). WB results showed that the SSN group and the SND group could reduce the expression of Smad2 and Smad3 (P < 0.05) and increase the expression of Smad7 (P < 0.05).

ABSTRACT

AIM: To explore the mechanism of action of alkaloid components of compound kushen Injection (CKI) in the treatment of lung cancer based on serum metabolomics, network pharmacology, and molecular docking techniques. METHODS: A lung cancer model was established in C57 mice by inoculation of Lewis mouse lung cancer tumor strain. Thirty male mice were randomly divided into normal group, model group and CKI group. The drug was administered by tail vein injection once daily for 17 consecutive days. Mouse serum was examined by ultrahigh performance liquid chromatography tandem mass spectrometry (LC-MS) metabolomics, and several multivariate statistical analyses including principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA), combined with databases such as the human metabolic database (HMDB) and related literature to identify and identify differential metabolites, the relevant metabolic pathways were searched for by the metaboanalyst online tool. Using network pharmacology, construct the“component-target-disease”network of CKI in the treatment of lung cancer. Molecular docking method was used to verify the interaction between potential active ingredients and core targets. Serum metabolomics was jointly analyzed with network pharmacology to construct a“metabolite-germinal-enzyme-gene” network. RESULTS: Through metabolomics technology, 16 differential metabolites associated with lung cancer were screened from serum, and CKI addback these differential metabolite levels compared with the model group. Metabolic pathways mainly involve retinol metabolism, tryptophan metabolism, glycerophospholipid metabolism and other metabolic pathways. Network pharmacology analysis indicated that CKI treatment of lung cancer mainly targets STAT3, MAPK3, and MAPK1, which are closely related to proteoglycans, cellular senescence, and HIF − 1 signaling pathways in cancer. CONCLUSION: This article explains the mechanism of CKI in treating lung cancer from the perspective of metabonomics and network pharmacology, and provides basis for further study of CKI.

ABSTRACT

OBJECTIVE To prepare Xiongzhi shigao decoction soluble microneedles, characterize it and investigate its transdermal properties in vitro. METHODS Two-step centrifugal method was used to prepare Xiongzhi shigao decoction soluble microneedles. The formability and mechanical property of the microneedles were evaluated from aspects of stroma fluidity, microneedle formability, needle hardness, etc. The appearance, mechanical strength, dissolution performance, skin barrier recovery performance and drug loading of the prepared microneedles were characterized by using active components of the soluble microneedle (chlorogenic acid, ferulic acid, notopterol, imperatorin, ligustilide, isoimperatorin) as indicators. The in vitro transdermal performance was investigated by Franz diffusion cell. RESULTS The soluble microneedle tips of Xiongzhi shigao decoction prepared in this study were conical, evenly distributed and of the same thickness, with good mechanical properties; the tip of the needle could be almost completely dissolved after being penetrated into the skin of rats for 2 hours, and the skin barrier recovery performance was good; the drug loading of chlorogenic acid, ferulic acid, notopterol, imperatorin, ligustilide and isoimperatorin were (87.04±1.12), (67.69±1.23), (20.65±0.17), (35.00±0.11), (153.83±0.21) and (23.52±0.50) μg per patch respectively. The results of in vitro transdermal study showed that cumulative release rates of 6 active components in this microneedle after 72 hours were 36.94%, 56.72%, 19.36%, 57.98%, 11.06% and 35.19%, respectively. CONCLUSIONS Xiongzhi shigao decoction soluble microneedles are prepared successfully in this study and have good formability, mechanical properties and pliable backing, which can significantly promote the transdermal drug delivery.

ABSTRACT

OBJECTIVE To evaluate the qualit y of Xihuang pills ,and to screen the differential markers affecting its quality . METHODS Using muskone as internal reference ,the content of α-pinene and other 4 components were determined by quantitative analysis of multi -components by single marker (QAMS),and compared with the results of external standard method . The fingerprints of 13 batches of Xihuang pills were established by gas chromatography (GC)method. Cluster analysis (CA)and orthogonal partial least squares discriminant analysis (OPLS-DA) were performed by SPSS 25.0 software and SIMCA 14.1 software. The variable importance projection (VIP)value greater than 1 was used as the standard to screen differential markers affecting the quality of the samples . RESULTS The contents of α-pinene,octyl acetate and β-elemene measured by QAMS were 0- 0.628 4,0.378 0-2.679 4 and 0.320 9-0.815 4 mg/g,respectively. The contents of α-pinene,octyl acetate ,β-elemene and musk ketone measured by external standard method were 0.001 5-0.627 1,0.378 0-2.594 7,0.329 2-0.837 0 and 0.385 7-0.806 0 mg/g, respectively. The relative error of the content determination results of the two methods was less than 4%. There were 26 common peaks in 13 batches of Xihuang pills ,and 3 common peaks ,such as octyl acetate ,β-elemene and musk ketone ,were identified ; their similarities were 0.912-0.946. 13 batches of samples could be divided into two categories (S1-S2,S6-S10,S13 were clustered into one category and S 3-S5,S11-S12 were clustered into one category ). VIP values of peak 7,11,10,17 and 16 were all greater than 1. CONCLUSIONS The content of 4 components such as α-pinene in Xihuang pills combined with GC fingerprint and chemical pattern recognition analysis can be used to evaluate the quality of Xihuang pills . The components corresponding to 5 common peaks such as peak 7 may be differential markers affecting the quality of the samples .

ABSTRACT

Liposomes have made remarkable achievements as drug delivery vehicles in the clinic. Liposomal products mostly benefited from remote drug loading techniques that succeeded in amphipathic and/or ionizable drugs, but seemed impracticable for nonionizable and poorly water-soluble therapeutic agents, thereby impeding extensive promising drugs to hitchhike liposomal vehicles for disease therapy. In this study, a series of weak acid drug derivatives were designed by a simplistic one step synthesis, which could be remotely loaded into liposomes by pH gradient method. Cabazitaxel (CTX) weak acid derivatives were selected to evaluate regarding its safety profiles, pharmacodynamics, and pharmacokinetics. CTX weak acid derivative liposomes were superior to Jevtana® in terms of safety profiles, including systemic toxicity, hematological toxicity, and potential central nerve toxicity. Specifically, it was demonstrated that liposomes had capacity to weaken potential toxicity of CTX on cortex and hippocampus neurons. Significant advantages of CTX weak acid derivative-loaded liposomes were achieved in prostate cancer and metastatic cancer therapy resulting from higher safety and elevated tolerated doses.

ABSTRACT

Tumor metastasis is responsible for chemotherapeutic failure and cancer-related death. Moreover, circulating tumor cell (CTC) clusters play a pivotal role in tumor metastasis. Herein, we develop cancer-specific calcium nanoregulators to suppress the generation and circulation of CTC clusters by cancer membrane-coated digoxin (DIG) and doxorubicin (DOX) co-encapsulated PLGA nanoparticles (CPDDs). CPDDs could precisely target the homologous primary tumor cells and CTC clusters in blood and lymphatic circulation. Intriguingly, CPDDs induce the accumulation of intracellular Ca

ABSTRACT

Pediatric patients usually require intravenous infusion maintenance fluid. Currently, maintenance fluid with 1/5 tension, 1/2 tension, and isotonic contraction were commonly used and lfuid with 1/5 tension and even with no tension is still commonly used. In recent years, a large number of high quality randomized controlled trials and meta analyses showed that compared with the traditional low tension maintenance lfuid, 1/2 tension or isotonic maintenance lfuid can effectively reduce the incidence of acute hyponatremia and the adverse reactions such as hypernatremia while hypernatremia were not caused. A number of national guidelines also recommend the use of 1/2 tension or isotonic contraction as a standard for maintaining liquid. In this paper, the present status and recent progress in the use of intravenous maintenance lfuid in pediatric patients were reviewed.

ABSTRACT

Objective To explore the influence factors of poor myocardial perfusion in patients with ST-segment elevation myocardial infarction( STEMI) after primary percutaneous coronary intervention(PCI). Methods One hundred and forty-three patients with first STEMI who were on admission from April 2010 to May 2014 and underwent primary PCI within 12 hours were enrolled as our subjects. According to the sum-ST-segment resolution(sumSTR)and TIMI myocardial perfusion grade(TMP)after primary PCI,all patients were divided into well myocardial perfusion group( sumSTR ≥ 50% or TMP 2 - 3 grade)and poor myocardial perfusion group(sumSTR < 50% and TMP 0 - 1 grade). The influence factors between two groups were collected and analyzed,including sex,age,pain to balloon time,blood pressure on admission,left ventricular ejection fraction,leucocyte count,neutrophil ratio(NR),high-sensitivity C-reactive protein(hs-CRP),blood lipid,and the history of hypertension,diabetes mellitus. Results The leucocytes count,NR,hs-CRP in patients of poor myocardial perfusion group were(11. 60 ± 3. 57)× 109 / L,0. 84 ± 0. 06 and 9. 80 ± 11. 37 mg/ L,higher than those in well myocardial perfusion group((9. 51 ± 2. 59)× 109 / L,0. 77 ± 0. 11 and(3. 83 ± 5. 58)mg/ L),and the differences were significant(t = 3. 497,P = 0. 001;t = 3. 390,P = 0. 001;t = 3. 973,P < 0. 001). Multiple linear regression analysis showed that neutrophil ratio was independent risk factor of sumSTR in STEMI patient after primary PCI(P = 0. 000). Conclusion The increase of leucocyte count,NR and hs-CRP are related to the poor myocardial perfusion after primary PCI. The increase of neutrophil ratio is an independent risk factor of poor myocardial perfusion.

ABSTRACT

Non-Camellia tea is a part of the colorful Chinese tea culture, and is also widely used as beverage and medicine in folk for disease prevention and treatment. In this study, 37 samples were collected, including 33 kinds of non-Camellia teas and 4 kinds of teas (Camellia). Traditional functions of non-Camellia teas were investigated. Furthermore, non-Camellia teas of original plants were characterized and identified by molecular methods. Four candidate regions (rbcL, matK, ITS2, psbA-trnH) were amplified by polymerase chain reaction. In addition, DNA barcodes were used for the first time to discriminate the commercial non-Camellia tea and their adulterants, and to evaluate their safety. This study showed that BLASTN and the relevant phylogenetic tree are efficient tools for identification of the commercial non-Camellia tea and their adulterants. However, some sequences from original plants have not been found and there is a limitation of sequence number of original plants in GenBank. Submitting more original plant sequences to the GenBank will be helpful for evaluating the safety of non-Camellia teas.

ABSTRACT

This study was aimed to optimize the best extraction technology of traditional Chinese medicine (TCM) Biminkang and establish the HPLC-ELSD method for determination of Astragaloside Ⅳ content. This test used heat-ing reflux which preferred ethanol as solvent extraction, extraction rate as an index to extract. By the single factor ex-periment, three factors which affect extraction rate greater were selected from the solvent concentration, extraction time, liquid ratio and extraction times. And then L9(34) orthogonal test was used to design the extraction technology of compound preparation Biminkang. HPLC-ELSD was performed on Diamonsil C18 column (250 mm í 4.6 mm, 5 μm) with H2O(A)-acetonitrile(B) (0~45 min: 22%B, 45~60 min: 22%~32%B) as mobile phase, flow rate was at 1.0 mL·min-1. The temperature of drift tube was 100℃ and the flow rate of N2 was 2.5 L·min-1. The column temperature was 30℃. The results showed that the best extraction technology of compound preparation Biminkang was liquid-solid ra-tio of 8 mL·g-1, ethanol concentration of 70%, 1.5 h for each extraction time, and extracted for three times. The re-sults showed that the presence of ethanol concentration and extraction times affected significantly. The ultimately de-termined optimal extraction conditions were as follows. The liquid-solid ratio of 8 mL/g, ethanol concentration of 70%, 1.5 h for each extraction time, and extracted for two times. The linear range of Astragaloside Ⅳ content was from 0.87 μg to 8.72 μg. And the regression equation was Y = 1.545 4X + 5.875 9, r = 0.999 7. The average re-covery rate was 95.05%. The RSD was 2.64%. It was concluded that the optimized extraction technology was stable, reasonably practicable, and suitable for industrial production.

ABSTRACT

Shikonin, a major component of Lithospermum erythrorhizon and Arnebia euchroma, exhibits antiinflammatory, immunomodulatory and antitumour activities. Although many recent studies have focused on the antitumour effects of shikonin, the exact mechanisms underlying its antitumour and immunomodulatory effects in tumour-bearing mice remain unclear. The aim of the present study was to investigate the antitumour and immunomodulatory effects of shikonin derivatives (ShD) in tumour-bearing mice. Swiss mice inoculated with hepatoma HepA(22) or sarcoma 180 (S(180)) cells were treated with ShD or 5-fluorouracil (5Fu). Survival time, immune organs, natural killer cell activity, lymphocytes, lymphocyte transformation and interleukin (IL)-2 production were analysed. ShD significantly prolonged the survival (median survival time prolonged by >7 days) of tumour-bearing mice in a dose-dependent manner, inhibited the growth of transplantable neoplasms (inhibitory rate, > 33%), and recovered (at [ShD] = 2.5 mg/kg/day) or increased (at [ShD] > 5 mg/kg/day) the number of CD3- and CD19-positive cells. ShD also played a role in protecting the immune organs from damage and reversed or enhanced immune responses, as noted by the nearly normal thymic structure; enlarged splenic corpuscles; and improved natural killer cell activity, lymphocyte transformation and IL-2 production in ShD-treated mice. ShD reduced the tumour load of tumour-bearing mice and protected the immune organs against tumour-induced damage and immune function impairment.

ABSTRACT

Background Researches have demonstrated that ocular hypertension induces the ischemia-reperfusion of retina and further leads to the degeneration of retinal ganglion cells,but its mechanism is beyond understanding.Objective The present study aims to observe the effects of static pressure on the morphology,proliferation activity and viability of cultured retinal microvascular endothelial cells (RMECs) and evaluate the expression of ET-1 and NO in these cells under variant static pressure.Methods RMECs were isolated from 30 healthy Wistar rats and cultured using explant culture method by Ⅷ factor antibody and PECAM-1 antibody.The static pressure of 1.33kPa,2.67kPa,5.33kPa and 10.67kPa was used in culture bottle respectively.The RMECs without static pressure were used as normal control group.The morphology of RMECs under the different static pressure was observed by inverted phase contrast microscopy,and the number of RMECs was counted using the counting plate.Cellular viability was studied by trypan blue staining.The changes of ET-1 and NO_2~-/NO_3~-,two metabolic products of NO,in the medium were detected by radioimmunoassay and Griess's nitrate reductase method.The expression of ET-1,eNOS and iNOS mRNA in RMECs was analyzed by semi-quantitative RT-PCR 24 hours after treatment of variant static pressure.Results Cultured RMECs sticked well at 24 hours and reached to confluence at 48 hours and showed the red fluorescence for Ⅷ factor antibody and PECAM-1 antibody.Enlargement of nuclei,extenders of cell bodies and suspension of RMECs in medium were observed.The number of RMECs was gradually increased.The cell viability was reduced with the raise of static pressure among these four groups(F=12.205,P<0.01;F=11.180,P<0.01).The static pressure increased the content of ET-1 released by RMECs in 2.67kPa,5.33kPa and 10.67kPa of static pressure groups,and concentrations of NO_2~-/NO_3~- in the medium showed a significant increase in 5.33kPa and 10.67kPa of static pressure groups compared with normal and 1.33kPa of static pressure groups(P<0.01).The expressions of ET-1 mRNA,eNOS mRNA and iNOS mRNA were considerably enhanced in 5.33kPa and 10.67kPa of static pressure groups compared with normal control group(P<0.01).Conclusion Raised static pressure causes the alteration of RMGCs structure and morphology.Static pressure could upregulate the expressions of ET-1,eNOS and iNOS mRNA in RMECs and increase the release of ET-1 and NO.This pathway might be one of pathologic mechanisms of retinal injury induced by high intraocular pressure.

ABSTRACT

Based on thermodynamic principle, the critical relative humidity of electrolytes is closely related to their solubility. The authors explored the relationship theoretically and calculated critical relative humidity of 21 electrolytes from their solubility in the light of Raoult's law and extended Wilson model. The results indicate that the critical relative humidity values calculated by Raoult's law can not accord with the reported ones and there is a systematic error in the high concentration range; while these calculated by extended Wilson model are comparable to the reported ones.
