ABSTRACT

This study investigated the effect and mechanism of morin in inducing autophagy and apoptosis in hepatocellular carcinoma cells through the protein kinase B(Akt)/mammalian target of rapamycin(mTOR)/signal transducer and activator of transcription protein 3(STAT3) pathway. Human hepatocellular carcinoma SK-HEP-1 cells were stimulated with different concentrations of morin(0, 50, 100, 125, 200, and 250 μmol·L~(-1)). The effect of morin on the viability of SK-HEP-1 cells was detected by Cell Counting Kit-8(CCK-8). The effect of morin on the proliferation and apoptosis of SK-HEP-1 cells was investigated using colony formation assay, flow cytometry, and BeyoClick~(TM) EdU-488 with different concentrations of morin(0, 125, and 250 μmol·L~(-1)). The changes in the autophagy level of cells treated with morin were examined by transmission electron microscopy and autophagy inhibitors. The impact of morin on the expression levels of proteins related to the Akt/mTOR/STAT3 pathway was verified by Western blot. Compared with the control group, the morin groups showed decreased viability of SK-HEP-1 cells in a time-and concentration-dependent manner, increased number of apoptotic cells, up-regulated expression level of apoptosis marker PARP, up-regulated phosphorylation level of apoptosis-regulating protein H2AX, decreased number of positive cells and the colony formation rate, an upward trend of expression levels of autophagy-related proteins LC3-Ⅱ, Atg5, and Atg7, and decreased phosphorylation levels of Akt, mTOR, and STAT3. These results suggest that morin can promote apoptosis, inhibit proliferation, and induce autophagy in hepatocellular carcinoma cells, and its mechanism of action may be related to the Akt/mTOR/STAT3 pathway.

ABSTRACT

【Objective】 To explore the rational management of contralateral patent processus vaginalis (CPPV) in laparoscopic high ligation of processus vaginalis. 【Methods】 A total of 300 children with unilateral oblique inguinal hernia/hydrocele who received laparoscopic high ligation of processus vaginalis in Baoding Children’s Hospital during Jun.2018 and Jun.2022 were selected and divided into two groups by random number table method, with 150 in either group. In the control group, 53 cases of CPPV were found intraoperatively, which were treated simultaneously. In the study group, 58 cases of CPPV were detected, among which 11 met the indications of high ligation and received simultaneous surgical treatment. The incidence of recurrence was compared between the two groups. 【Results】 After 1 year of follow-up, the recurrence rate was 8.62% in the study group and 1.88% in the control group (P>0.05). The detection rate of CPPV was 23.02% in children with unilateral inguinal hernia, significantly lower than that in children with unilateral hydrocele (49.07%, P<0.001). The detection rate of CPPV was 42.71% in children with left patent processus vaginalis and 32.95% in children with right patent processus vaginalis (P=0.19). The detection rate of CPPV was 62.93% in the age group of 1-2 years, significantly higher than that in other age groups (P<0.001). 【Conclusion】 The incidence of CPPV conversion into oblique inguinal hernia or hydrocele is low. Only children who meet the indications can be treated at the same time during surgery.

ABSTRACT

Cancer still has elevated morbidity and mortality, which undoubtedly impacts the life quality of affected individuals. Remarkable advances have been made in cancer therapy, although the toxicities of traditional therapies remain an obvious challenge. Dahuang Zhechong Pill (DHZCP), developed by Zhongjing Zhang in the Synopsis of the Golden Chamber, represents an effective anticancer traditional Chinese medicine (TCM). In this review, it was found that DHZCP is therapeutically utilized in liver, lung, gastric, pancreatic and other cancers in clinic. Pharmacological evidence showed that its anti-tumor mechanisms mainly involve induced cell cycle arrest, apoptosis and autophagy, as well as suppressed tumor cell proliferation, obstructed angiogenesis and metastasis, enhanced immunity, and reversal of multidrug resistance. The present review provides a solid basis for the clinical application of DHZCP and may promote the wide use of TCM in clinical antitumor application.

ABSTRACT

This study aimed to investigate the effect and molecular mechanism of sinomenine on proliferation, apoptosis, metastasis, and combination with inhibitors in human hepatocellular carcinoma HepG2 cells and SK-HEP-1 cells. The effect of sinomenine on the growth ability of HepG2 and SK-HEP-1 cells were investigated by CCK-8 assay, colony formation assay, and BeyoClick~(TM) EdU-488 staining. The effect of sinomenine on DNA damage was detected by immunofluorescence assay, and the effect of sinomenine on apoptosis of human hepatocellular carcinoma cells was clarified by Hoechst 33258 staining and CellEvent~(TM) Cystein-3/7Green ReadyProbes~(TM) reagent assay. Cell invasion assay and 3D tumor cell spheroid invasion assay were performed to investigate the effect of sinomenine on the invasion ability of human hepatocellular carcinoma cells in vitro. The effect of sinomenine on the regulation of protein expression related to the protein kinase B(Akt)/mammalian target of rapamycin(mTOR)/signal transducer and activator of transcription 3(STAT3) signaling pathway in HepG2 and SK-HEP-1 cells was examined by Western blot. Molecular docking was used to evaluate the strength of affinity of sinomenine to the target cysteinyl aspartate specific proteinase-3(caspase-3) and STAT3, and combined with CCK-8 assay to detect the changes in cell viability after combination with STAT3 inhibitor JSI-124 in combination with CCK-8 assay. The results showed that sinomenine could significantly reduce the cell viability of human hepatocellular carcinoma cells in a concentration-and time-dependent manner, significantly inhibit the clonogenic ability of human hepatocellular carcinoma cells, and weaken the invasive ability of human hepatocellular carcinoma cells in vitro. In addition, sinomenine could up-regulate the cleaved level of poly ADP-ribose polymerase(PARP), a marker of apoptosis, and down-regulate the protein levels of p-Akt, p-mTOR, and p-STAT3 in human hepatocellular carcinoma cells. Molecular docking results showed that sinomenine had good affinity with the targets caspase-3 and STAT3, and the sensitivity of sinomenine to hepatocellular carcinoma cells was diminished after STAT3 was inhibited. Therefore, sinomenine can inhibit the proliferation and invasion of human hepatocellular carcinoma cells and induce apoptosis, and the mechanism may be attributed to the activation of caspase-3 signaling and inhibition of the Akt/mTOR/STAT3 pathway. This study can provide a new reference for the in-depth research and clinical application of sinomenine and is of great significance to further promote the scientific development and utilization of sinomenine.

ABSTRACT

Objective:To evaluate the short-term outcomes of aortic root repair using a pericardial autograft for acute type A aortic dissection.Methods:Between January 2020 and August 2021, 12 patients underwent aortic root repair using a pericardial autograft for type A aortic dissection. There were 8 males and 4 females, aged from 32.0 to 71.0 years, with a mean of (49.1±13.0) years, weight from 40.0 to 100.0 with a mean of (78.6±20.5) kg. Short-term outcomes were assessed by cardiopulmonary bypass time, cross-clamp time, circulatory arrest time, mechanical ventilation time, ICU time, postoperative stay time. The diameter of Valsalva sinus and aortic regurgitation were assessed before, after operation and during follow-up.Results:There were no postoperative and follow-up death. Cardiopulmonary bypass time was(256.4±60.6)min, ranging from 182.0 to 243.0 minutes; cross-clamp time was(195.0±52.5)minutes, ranging from 127.0 to 284.0 minutes; circulatory arrest time was(19.9±3.6)min, ranging from 15.0 to 25.0 min; mechanical ventilation time was (69.1±72.1)hours, ranging from 6.4 to 250.3 h; ICU time was (143.6±81.7) h, ranging from 56.9 to 288.0 h; postoperative stay time was (12.8±4.1) days, ranging from 8.0 to 20.0 days. One patient had transient paralysis (8.3%), and one patient needed hemofiltration due to acute kidney failure (8.3%), they all completely recovered before discharge. Follow-up time ranged from 10.0 to 21.0 months, with a median of 13 months. Heart function (NYHA) was I to II degrees. The mean diameter of aortic root was (36.7±5.8)mm(27.0-45.0 mm) preoperatively, (35.8±5.1)mm (25.0-44.8 mm) before discharge, and (35.7±5.9)mm (25.1-44.8 mm) during follow-up, respectively. There was no significant difference between them ( P>0.05). The preoperative aortic regurgitation was as follow: severe aortic regurgitation 2, moderate 1, mild to moderate 3, mild 1, trivial 1, none 4; postoperative aortic regurgitation: mild 2, trivial 2, none 8; follow-up aortic regurgitation: mild 3, trivial 1, none 8. Conclusion:Aortic root repair with a pericardial autograft is a safe and effective technique to treat acute type A dissection involving the sinus. Using this technique, residual dissection tissues could be significantly reduced, which subsequently decreases the risk of proximal bleeding, maintains the function of sinus, and increases long-term durability. Short-term results are satisfactory, and the long-term results need further follow-up.

ABSTRACT

The field of two-dimensional (2D) nanomaterial-based cancer immunotherapy combines research from multiple subdisciplines of material science, nano-chemistry, in particular nano-biological interactions, immunology, and medicinal chemistry. Most importantly, the "biological identity" of nanomaterials governed by bio-molecular corona in terms of bimolecular types, relative abundance, and conformation at the nanomaterial surface is now believed to influence blood circulation time, bio-distribution, immune response, cellular uptake, and intracellular trafficking. A better understanding of nano-bio interactions can improve utilization of 2D nano-architectures for cancer immunotherapy and immunotheranostics, allowing them to be adapted or modified to treat other immune dysregulation syndromes including autoimmune diseases or inflammation, infection, tissue regeneration, and transplantation. The manuscript reviews the biological interactions and immunotherapeutic applications of 2D nanomaterials, including understanding their interactions with biological molecules of the immune system, summarizes and prospects the applications of 2D nanomaterials in cancer immunotherapy.

ABSTRACT

Objective::To explore the pharmacological mechanism of Xiao Xianxiongtang in treating type 2 diabetes mellitus (T2DM) by network pharmacology. Method::The main active ingredients, corresponding targets and target genes of Xiao Xianxiongtang were searched on Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) website. Relevant target genes of T2DM were obtained through Gene Cards. The targets of drug active ingredients were mapped to the targets of T2DM, and the intersection targets were obtained as the predictive targets of Xiao Xianxiongtang on T2DM. Cytoscape 3.7.1 software was used to construct the drug active ingredient-intersection target network model and select the key active ingredients. Interactive protein-protein interaction network (PPI) was constructed by STRING website, and key target genes were selected. Gene function analysis (GO) and enrichment analysis based on the Kyoto encyclopedia of genes and genomes (KEGG) pathway were performed on the intersecting targets using DAVID6.8 online tool. Result::Xiao Xianxiongtang had 30 active ingredients, 156 relevant targets, 14 key active ingredients and 18 key target genes on T2DM. GO analysis showed that the biological functions of Xiao Xianxiongtang in the treatment of potential genes of T2DM mainly involved transcriptional regulation, oxidative stress, protein binding and inflammatory reaction. KEGG pathway enrichment showed that the main pathways of Xiao Xianxiongtang in the treatment of T2DM were hypoxia inducible factor-1 (HIF-1) signaling pathway, tumor necrosis factor (TNF) signaling pathway, Toll-like receptor signaling pathway and thyroid hormone signaling pathway, phosphatidylinositol 3 kinase/protein kinase B (PI3K/Akt) signaling pathway, hepatitis B, hepatitis C, tyrosine kinase receptor2(ErbB) signaling pathway, calcium signaling pathway and nuclear factor-kappa B (NF-κB) signaling pathway. Conclusion: Xiao Xianxiongtang is a multi-component, multi-target and multi-pathway process in the treatment of T2DM. It plays an important role in the treatment of T2DM by regulating transcription, oxidative stress, protein binding and inflammatory reaction. Conclusion::The mechanism of Xiao Xianxiongtang in treating T2DM may alleviate insulin resistance, increase insulin sensitivity and reduce blood sugar by inhibiting the secretion of inflammatory factors, participating in anti-inflammatory response, reducing oxidative stress, increasing intracellular calcium concentration, blocking glucagon signaling pathway and activating PI3K/Akt pathway.

This article elaborated the theory of chronic and complex disease treatment based on collaterals. It put forward that complex virtual evil stasis was the common pathogenesis of chronic and complex disease treatment. Combined with articles published in recent 5 years, from the perspective of cytokines and genes, it summarized traditional Chinese medicine (TCM) compound targets in chronic and complex disease treatment. It put forward the transforming growth factor-β1 (TGF-β1), tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), vascular endothelial growth factors (VEGFs), matrix metalloproteinases/tissue inhibitor of metalloproteinase (MMPs/TIMPs) were its high-frequency targets. It provided a basis for future experiment design on chronic and complex disease treatment based on collaterals as well as new drug development.

ABSTRACT

This study was aimed to discuss the anti-inflammatory and immunization properties ofRe-Du-Ning (RDN) injection in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with phlegm-heat stagnated in the lung syndrome. A total of 110 in-patients were collected from January 2012 to December 2013. Cases were randomly divided into the treatment group (basic treatment plan + 20 ml RDN injection + 250 mL of 5% GS injection, once a day, intravenous injection) and the control group (basic treatment plan + 20 ml of 0.9% NS injection + 250 mL of 5% GS injection, once a day, intravenous injection), with 55 cases in each group. The treatment course was 14 days. Observations were made on traditional Chinese medicine (TCM) symptom score, clinical effect, blood routine examination, blood gas analysis and T lymphocyte subgroups before and after the treatment in both groups. The results showed that in the aspects of TCM symptom score and clinical effect, the posttreatment TCM symptom score and total integration in the treatment group were obviously improved compared to the control group except for shortness of breath, dry mouth and thirsty, flushing (P < 0.05). The total effective rate was obviously better than that of the control group. In the aspect of anti-inflammation, the total white blood cell (WBC) count and the normal neutrophil percentage of both pretreatment and posttreatment in the treatment group were obviously decreased compared to pretreatment (P < 0.05). However, there were no statistical differences on WBC count and normal neutrophil percentage compared to posttreatment in the control group. In the aspect of blood gas analysis, the posttreatment PaCO2 and PaO2 of the treatment group were obviously better than the control group (P < 0.05). In the aspect of immune regulation, the posttreatment T lymphocyte subgroups CD3+ and CD4+ of the treatment group were higher than the control group. The expression inhibition / cytotoxic lymphocyte (CD8+) was obviously lower than the control group (P < 0.05). The CD4+ / CD8+ was back to the normal reference level. It was concluded that in the treatment of AECOPD with phlegm-heat stagnated in the lung syndrome, on the basis of western medicine symptomatic treatment plan, RDN injection was assisted to clear heat, relieve toxin and remove phlegm. It can obviously improve patient’s clinical symptoms and increase the clinical therapeutic effects. The treatment was especially targeted to infection-induced respiratory failure patients combined low immunity with possible identified therapeutic effects.
