Abstract:
[Abstract]Objective To explore the effect and mechanism of Bajitianwan on preventing D-galactose (D-gal)-induced osteoblast bone loss.   Methods  Osteoblasts isolated from 24hold Wistar rats were injured by D-gal and intervened with Bajitianwan extract. The osteoblastic proliferation and differentiation were determined by MTT and alkaline phosphatase (ALP), respectively. The cell reactive oxygen species (ROS) levels were detected by DCFH-DA fluorescent probes. The expression of cellular oxidation-related protein nuclear factor erythroid 2-related factor 2 (Nrf2), phosphorylated protein kinase B (p-AKT), protein kinase B (AKT), heme oxygenase-1 (HO-1), and NADPH quinone oxidoreductase 1 (NQO1) were detected by Western blotting. The intranuclear expression of Nrf2 protein was measured by immunofluorescence.   Results  Bajitianwan extract had significantly increased the osteoblastic proliferation and differentiation, and significantly reduced the intracellular ROS level. Bajitianwan extract had activated the PI3K/AKT pathway via activating the phosphorylation of AKT in osteoblasts, and promoted NQO1 and HO-1 expression. In addition, Bajitianwan had significantly promoted the expression of Nrf2 in the nucleus of osteoblasts, activating Nrf2 signaling pathway, and further promoted bone formation.   Conclusion  This study confirmed that Bajitianwan could prevent D-gal injured osteoblastic bone loss for the first time. The mechanism might be related to the regulation of oxidative stress associated PI3K/AKT and Nrf2 signaling pathway.

Abstract:
Glioma is a common primary malignant brain tumor. At present, the main clinical treatment is surgical resection combined with radiotherapy and chemotherapy. Due to the selective permeability of the blood-brain barrier and the characteristics of multi-drug resistance of tumor cells, the therapeutic effect is not ideal. In recent years, studies have found that borneol could open the blood-brain barrier and promote the infiltration of chemotherapy drugs. When borneol is combined with or co-carried with chemotherapy drugs, chemotherapy drugs could target more glioma tissues and increase efficacy. The preclinical studies on the combination of borneol and chemotherapy drugs in recent years were reviewed in this article, in order to provide useful reference for the treatment of glioma.

Abstract(250) HTML(112) PDF (1182KB)(1)
Abstract:
The transcription factor ZNF24 (also known as ZNF191 or KOX17) is a member of the Krüppel-like zinc finger transcription factor family, with a leucine-rich (Leu) SCAN domain (also known as LeR domain) at the N-terminus and four consecutive typical Kruppel-like zinc finger modities at the C-terminus. ZNF24 is a multifunctional transcription factor involved in the regulation of kinase transcriptional activity, vascular proliferation and development, especially in tumorigenesis and tumor progression. ZNF24 plays an important and complex dual-directional regulation role (promoting and inhibiting) in tumor development, invasion and metastasis by regulating the transcriptional expression of different target genes (such as VEGF, Wnt8B, Twist1, β-catenin and DGL1, etc.) and the competitive binding with protein factors (such as β-catenin). Therefore, elucidating the mechanism of ZNF24 in tumors would provide clues and ideas for the treatment of tumors. The researches status of ZNF24 in tumors were summarized in this paper.

Abstract:
  Objective   To optimize the microwave-assisted extraction process of green tea polyphenols.   Methods   The extraction yield of tea polyphenols was figured up by building the standard curve of gallic acid and examining the concentration of tea polyphenols in green tea extract with the introduction of a correction factor. The effects of four single factor levels of microwave extraction time, microwave output power, liquid-to-material yield, and ethanol volume fraction on the extraction yield of tea polyphenols were primarily studied in this experiment. The response surface was applied to further optimize the extraction process of green tea polyphenols after exploring the appropriate range of four single factor levels.   Results   The optimal extraction process was as follows: extraction time 37 s, microwave output power 350 w, material - liquid yield 1:45 (g/ml), ethanol volume fraction 55%, and the actual extraction yield of tea polyphenols was 25.65%, which was not much different from the theoretical value.   Conclusion   The microwave-assisted green tea polyphenol extraction process optimized by response surface methodology is time-saving and practicable, and the extraction yield is high.

Abstract:
Diabetic nephropathy (DN) is a common microvascular complication of type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM), which is also the main cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD). However, the treatment methods are limited at present. More and more evidences have indicated that inflammatory response is involved in the pathogenesis and progression of diabetic nephropathy (DN).Several anti-inflammatory strategies that target specific inflammatory mediators (transcription factors, pro-inflammatory cytokines, chemokines, adhesion molecules) and intracellular signaling pathways have shown benefits in the DN rodent model. The mechanisms related to inflammation in the development and progression of DN were summarized and new strategies to prevent or treat DN based on inflammation were briefly discussed in this review.

Abstract:
  Objective  To explore the effects of Cordyceps sinensis extract (CSE) on osteoporosis and RANKL-mediated osteoclastogenesis.   Methods  Bone marrow-derived macrophages (BMMs) was isolated from the Bone marrow of C57BL/6 mice. CSE was added in osteoclast differentiation. Osteoclasts were stained by tartrate-resistant acid phosphatase (TRAP). The nearly mature osteoclasts were planted on hydroxyapatite plates and the area of bone lacunae was observed by microscope. The F-actin belt was stained by DAPI and phylloeptide and the number of nuclei was observed by confocal microscopy. The expressions of DC-STAMP, ATP6V0D2, TRAP, CTSK, and NFATC1 were detected by q-PCR. The protein expression of the MAPK pathway was detected by Western Blot. The in vivo experiments were carried out by administering CSE to the ovariectomized mice daily through gavage. After 6 weeks of intervention, mouse femurs were taken for morphological analysis. Peripheral blood was taken for ELISA.   Results  CSE represses osteoclastogenesis, bone resorption, F-actin belts formation, osteoclast specific gene expressions and MAPK signaling pathways in vitro. In vivo study indicated that CSE prevents OVX-induced osteoporosis and preserves bone volume by repressing osteoclast activity and function. It also increases the serum ALP, BGP content, and reduces TRAP content.   Conclusion  CSE can attenuate osteoclast formation and OVX-induced osteoporosis, suggesting potential clinical therapeutic effects for osteoporosis.

Abstract:
Objective To explore the function of short-chain dehydrogenases/reductases (SDRs) in safflower flavonoid, especially hydroxysafflower yellow A (HSYA) biosynthesis.   Methods  SDRs involved in HSYA biosynthesis pathway were screened based on safflower transcriptome database and metabolome database. The expression pattern was analyzed by qRT-PCR. The overexpression vector was constructed by seamless cloning technology, then genetically transformed to the Yunnan Weishan safflower strain by Agrobacterium gv3101. The transgenic T2 generation plants were positively verified, and the gene expression of corolla SDRs was analyzed. The content of secondary metabolites was assayed by UPLC-Q-TOF/MS.   Results  Three SDRs genes named CtSDR1, CtSDR2 and CtSDR3 involved in HSYA biosynthesis pathway were screened. Their expression in safflower from high to low was corolla > leaf > stem > root. The expression level in corolla increased gradually with corolla development. qRT-PCR analysis of corolla with positive verification of genome insertion sequence showed that the transcription level of CtSDR3 in corolla of T2 positive plants increased by 2~3 times compared with the blank control group, and the content of secondary metabolite HSYA increased by 7.1%~16.6% (P< 0.05).   Conclusion  CtSDR3 may be involved in the biosynthesis of flavonoids, especially HSYA, in safflower. It provides the support data for explaining the function of CtSDR3 in HSYA biosynthesis pathway.

Abstract:
  Objective  To study the effect of traditional Chinese medicine, Syngnathus on learning and memory impairment induced by D-galactose in aging mice and its mechanism of action.  Methods  HPLC was used to determine the content of DHA, the active ingredient in anti-learning and memory impairment in Syngnathus. The aging mouse model was prepared by intraperitoneal injection of D-galactose (D-gal). Morris water maze test and Western blot were used to detect the ability of learning and memory, biochemical indicators and protein expression related to oxidative damage in the hippocampus, and to explore the protective effect and mechanism of Syngnathus on learning and memory impairment in aging mice.  Results  HPLC results showed that the DHA content in Syngnathus was 7.7613 mg/g (calculated as crude drug), accounting for about 47% of the total composition. Morris water maze results showed that Syngnathus could reduce the escape latency of learning and memory-impaired aging mice and increase the target quadrant swimming time, the proportion of swimming distance and the number of times of crossing the platform, and improve the learning and memory impairment of mice. In addition, Syngnathus can activate the AKT/FOXO1/SOD2 signaling pathway in the hippocampus of aging mice with learning and memory impairment, promote the expression of oxidative stress pathway-related proteins, and improve the learning and memory impairment in aging mice by reducing the degree of oxidative damage in the hippocampus of aging mice.  Conclusion  This study found that Syngnathus is rich in DHA, which has the effect of improving learning and memory impairment induced by D-galactose in aging mice, and preliminarily clarified that its mechanism of action is related to anti-oxidation. Experimental evidence is provided.

Abstract:
As an increasingly mature analytical technique, surface-enhanced Raman spectroscopy has the ability to identify, detect, and even quantitatively measure many single substances in nature. However, in the actual sample analysis, the tested samples were often a mixed system of various substances, and it was impossible to accurately characterize the components of the mixed system only by relying on SERS technology. Therefore, SERS combined with other techniques to accurately determine the measured substances has become an inevitable trend. Through the combination, the deficiency of SERS in detection and characterization was improved, and the purpose of efficient, sensitive and accurate determination of substances to be measured was achieved.

Abstract:
  Objective  To explore the molecular targets and associated potential pathways of Kunxian capsule in the treatment of rheumatoid arthritis (RA) based on network pharmacology.  Methods  The constituents of Kunxian capsule were searched by Traditional Chinese Medicine Systems Pharmacology Database, Analysis Platform (TCMSP) and a high-throughput experiment- and reference-guided database of traditional Chinese medicine(HERB).The potential active ingredients and targets were retrieved based on TCMSP database. RA related gene targets were retrieved through GeneCards database and OMIM database. Venn online software was used to obtain the common target of drugs and diseases. The “compound-target” network diagram was constructed with Cytoscape software. String database was used to draw the protein interaction (PPI) network. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the intersection network were conducted by Bioconductor Database.   Results  81 active ingredients and 913 targets were identified. 228 targets were obtained after removing the duplicates. 4494 target genes directly related to RA were obtained from the GeneCards databases and OMIM databases. 162 genes were obtained from the intersection of component-target and disease-target. It was revealed that five ingredients including quercetin, luteolin, kaempferol, β-sitosterol and triptolide are the main active ingredients in Kunxian capsule. AKT1, IL-10, STAT3, CASP8 and CDKN1A may be the main therapeutical targets. The results of GO and KEGG enrichment analysis showed that the mechanism of Kunxian capsule is mainly related to the regulation of reactive oxygen metabolism, the regulation of kinase activity, and IL-17 signaling pathway. The important biological processes and signaling pathways include infection, inflammation and immunity.   Conclusion  This research preliminarily explored the mechanism of Kunxian capsule in the treatment of RA by network pharmacology and suggested that the overall regulation is characterized by multi-components, multi-targets, and multi-channels. It provided some ideas for further molecular biology experiments.

  Objective  To study the acute toxicity of tetrodotoxin to zebra fish.   Methods  The maximum non-lethal concentration (MNLC) and 10% lethal concentration (LC10) determinations were used to assess the acute toxicity of tetrodotoxin.   Results  According to the simulation calculation of Origin 8.0 software, the MNLC was 8.62 µmol/L and 15.2 µmol/L for LC10. Under the experimental conditions, tetrodotoxin at a concentration of 16.0 µmol/L and above induced pericardial edema and arrhythmia, leading to the death of zebra fish. The target organs for acute toxicity of tetrodotoxin were the heart and liver. The main manifestations were pericardial edema, arrhythmia, and delayed yolk sac absorption. The toxicity appeared at a concentration of 0.958 µmol/L.   Conclusion  Tetrodotoxin has heart and liver toxicity to zebra fish, and its toxicity is dose-dependent.

Abstract:
  Objective  To investigate the influence of renal failure on the area under curve (AUC) and adverse reactions of docetaxel in breast cancer patients, and provide evidence for the dosage of docetaxel in renal failure patients.   Methods  A retrospective study was conducted on 24 patients with breast cancer who had undergone radical mastectomy and received AC-T adjuvant chemotherapy in our hospital from January 2019 to November 2021. According to renal function cases, the patients were divided into two groups: renal failure group (n=5) and normal renal function group (n=19). The clinical characteristics such as gender, age, body weight and body surface area of patients in two groups, docetaxel dose, blood concentration, area under the curve, liver and kidney function, white blood cell count and absolute value of neutrophil before chemotherapy were collected. Single factor linear regression was used to analyze the influencing factors of the AUC of docetaxel. Adverse reactions after chemotherapy with docetaxel including nausea and vomiting, bone marrow suppression, constipation and liver function injury were collected. CTCAE 4.0 evaluation standard was used to evaluate adverse reactions.   Results  The clinical characteristics of creatinine [908.0 (819.0, 1018.0) μmol/L vs 54.8 (52.0, 65.0) μmol/L] and creatinine clearance rate [4.9 (4.3, 5.4) ml /min vs 86.3 (59.3, 92.5) ml/min] of the renal failure group and the normal renal function group have significant difference (P<0.001), while no significant difference (P>0.05) were found in the body surface area [1.4 (1.4, 1.5) m2 vs 1. 6 (1.5, 1.6) m2], docetaxel dose [70.4 (69.4, 73.0) mg/m2 vs 74.4 (72.3, 91.2) mg/m2], body weight [(51.4±3.8) kg vs (51.5±5.5) kg]. Liver function, white blood cells and neutrophils were within the normal range before chemotherapy with docetaxel. There was no significant difference in AUC value [(1.6±0.6) mg·h/L vs (1.8±0.8) mg·h/L] between the two groups after chemotherapy with docetaxel (P>0.05). Linear univariate regression analysis indicated that the blood concentration at the end of docetaxel infusion was significantly associated with AUC of docetaxel (P<0.001), while the body surface area, dose of docetaxel, body weight, liver and kidney function were not correlated with AUC of docetaxel (P>0.05). After chemotherapy with docetaxel, adverse reactions of patients in the two groups: nausea and vomiting (grade I incidence: 40% vs. 57.9%, grade II incidence: 60% vs. 42.1%), myelosuppression (grade I incidence: 60% vs. 84.2%, grade II incidence: 20% vs 15.8%) and constipation (all mild constipation) had no significant difference (P>0.05).   Conclusion  Renal failure did not affect the exposure of docetaxel and the adverse reactions after chemotherapy with docetaxel in breast cancer patients.

Abstract:
  Objective  To evaluate the effect of Ulinastatin injection on inflammation, hemodynamics, oxygenation index (PaO2/FiO2) and prognosis in patients with septic shock.   Methods  A retrospective analysis was performed on clinical data of 109 patients with septic shock from January 2017 to December 2019. Patients were divided into observation group (n=73) and routine group (n=54) according to the treatment regimens. The two groups were given anti-shock treatment according to the relevant guidelines, and observation group was additionally given Ulinastatin. The inflammatory factors, hemodynamic parameters and PaO2/FiO2 and recovery were compared between the two groups before and after treatment.   Results  The levels of IL-6, TNF-α and PCT at 7 d of treatment were significantly decreased in the two groups (P<0.05), and the levels of IL-6, TNF-α and PCT of observation group were lower than that of routine group (P<0.05). At 12 h, 24 h and 72 h of treatment, the MAP, CI and PaO2/FiO2 were significantly increased in the two groups (P<0.05) while the EVLWI and SVRI were significantly decreased (P<0.05), and the MAP and PaO2/FiO2 of observation group at the same time were higher than that of routine group while the EVLWI was lower than that routine group (P<0.05). At 7 d of treatment, the APACHE-II score, mechanical ventilation time and ICU stay time of observation group were lower than that of routine group, and the incidence rates of MODS in the two groups were 4.11% and 14.81% respectively (P<0.05), and the mortality rates were 1.37% and 7.41% respectively (P>0.05).   Conclusion  Ulinastatin could be beneficial in septic shock, which could reduce inflammatory response, improve hemodynamic parameters and microcirculation perfusion, and put a positive effect on promoting rehabilitation and improving prognosis.
