ABSTRACT

To establish an ultra high performance liquid chromatography coupled with pre-column derivatization method for simultaneous determination of 17 kinds of free amino acid concentrations in CHO cell which expressed high levels of programmed death protein-1 (PD-1) antibody, and its amino acid metabolism was analyzed by this method. Using 6-aminoquinoline-N-hydroxysuccinimidyl carbamate (AQC) as a derivatization reagent, the free amino acids in different concentrations of amino acid standards or cell lines were transformed into stable UV-absorbent compounds, which were separated by gradient elution through ACQUITY UPLC BEH C18 (2.1 mm × 100 mm, 1.7 μm) column. The flow rate was set at 0.7 mL·min-1, the column temperature at 55 ℃, the loading amount of sample at 1 µL, the UV detection wavelength at 260 nm, and then the free amino acid concentration in cell lines which expressed PD-1 antibody was determined by external standard method. According to the changes of amino acids concentration during the process of cell culture, the amino acid metabolism was analyzed. The results showed that pre-column derivatization high performance liquid chromatography could completely separate 17 kinds of amino acids within 11 minutes, has good linear relationship (R2 ≥ 0.999 3) in the range of 0.75-500 μmol·L-1, the limits of detection was 0.1-0.3 μmol·L-1, the limits of quantitative was 0.5-1 μmol·L-1. The established method is quickly and reproducibility. Amino acid metabolism revealed that methionine, isoleucine and leucine may be the restrictive factors of expression for cell line. This method can be used for detection changes of free amino acid concentration in cell line.

ABSTRACT

This study aimed to investigate the biological effects and underlying mechanisms of the total ginsenosides from Panax ginseng stems and leaves on lipopolysaccharide(LPS)-induced acute lung injury(ALI) in mice. Sixty male C57BL/6J mice were randomly divided into a control group, a model group, the total ginsenosides from P. ginseng stems and leaves normal administration group(61.65 mg·kg~(-1)), and low-, medium-, and high-dose total ginsenosides from P. ginseng stems and leaves groups(15.412 5, 30.825, and 61.65 mg·kg~(-1)). Mice were administered for seven continuous days before modeling. Twenty-four hours after modeling, mice were sacrificed to obtain lung tissues and calculate lung wet/dry ratio. The number of inflammatory cells in bronchoalveolar lavage fluid(BALF) was detected. The levels of interleukin-1β(IL-1β), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) in BALF were detected. The mRNA expression levels of IL-1β, IL-6, and TNF-α, and the levels of myeloperoxidase(MPO), glutathione peroxidase(GSH-Px), superoxide dismutase(SOD), and malondialdehyde(MDA) in lung tissues were determined. Hematoxylin-eosin(HE) staining was used to observe the pathological changes in lung tissues. The gut microbiota was detected by 16S rRNA sequencing, and gas chromatography-mass spectrometry(GC-MS) was applied to detect the content of short-chain fatty acids(SCFAs) in se-rum. The results showed that the total ginsenosides from P. ginseng stems and leaves could reduce lung index, lung wet/dry ratio, and lung damage in LPS-induced ALI mice, decrease the number of inflammatory cells and levels of inflammatory factors in BALF, inhibit the mRNA expression levels of inflammatory factors and levels of MPO and MDA in lung tissues, and potentiate the activity of GSH-Px and SOD in lung tissues. Furthermore, they could also reverse the gut microbiota disorder, restore the diversity of gut microbiota, increase the relative abundance of Lachnospiraceae and Muribaculaceae, decrease the relative abundance of Prevotellaceae, and enhance the content of SCFAs(acetic acid, propionic acid, and butyric acid) in serum. This study suggested that the total ginsenosides from P. ginseng stems and leaves could improve lung edema, inflammatory response, and oxidative stress in ALI mice by regulating gut microbiota and SCFAs metabolism.

ABSTRACT

Background/Aims@#We aimed to investigate the comfort, safety, and endoscopic visibility during esophagogastroduodenoscopy (EGD) afforded by a modified 4-hour semifluid and 2-hour water (“4+2”) fasting protocol. @*Methods@#In this parallel group, endoscopist-blinded, randomized controlled trial, outpatients undergoing unsedated diagnostic EGD from 10:30 AM to 12:00 PM were randomly assigned to either a “4+2” protocol group or a conventional fasting group. The participants’ comfort during the fasting period and procedure was measured using the visual analog scale, and mucosal visibility was measured by endoscopists using the total visibility score. Satisfaction was defined as a visual analog scale score of ≤3. The primary outcome was the participants’ comfort during fasting. @*Results@#One hundred and six and 108 participants were randomized to the “4+2” protocol and control groups, respectively. Participants’ comfort before EGD was significantly higher in the “4+2” protocol group measured by both the proportion of satisfaction (86.8% vs 63.9%, p=0.002) and the visual analog scale score (median [interquartile range]: 1.0 [1.0–2.0] vs 3.0 [1.0–4.0], p<0.001). The proportion of satisfaction during EGD also significantly improved (59.4% vs 45.4%, p=0.039) in the “4+2” protocol group. The total visibility score was unaffected by the fasting protocol (5.0 [4.0–5.0] vs 4.0 [4.0–5.0], p=0.266). No adverse events were observed during the study. @*Conclusions@#The “4+2” protocol was more comfortable and provided equal mucosal visibility and safety compared with conventional fasting for unsedated EGD.

ABSTRACT

The study investigated the effect of Buyang Huanwu Decoction(BYHWD) on endogenous biomarkers in the urine of rats with chronic inflammation induced by lipopolysaccharide(LPS) using ultra-high performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS), aiming to elucidate the molecular mechanism underlying the therapeutic effect of BYHWD on chronic inflammation from a metabolomics perspective. Male SD rats were randomly divided into a normal group, a model group, and low-, medium-, and high-dose BYHWD groups(7.5, 15, and 30 g·kg~(-1)). The model group and BYHWD groups received tail intravenous injection of LPS(200 μg·kg~(-1)) on the first day of each week, followed by oral administration of BYHWD once a day for four consecutive weeks. Urine samples were collected at the end of the administration period, and UPLC-Q-TOF-MS was used to analyze the metabolic profiles of the rat urine in each group. Multivariate statistical analysis methods such as principal component analysis(PCA), partial least squares-discriminant analysis(PLS-DA), and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to analyze the effect of BYHWD on endogenous metabolites. One-way ANOVA and variable importance for the projection(VIP) were used to screen for potential biomarkers related to chronic inflammation. The identified biomarkers were subjected to pathway and enrichment analysis using MetaboAnalyst 5.0. A total of 25 potential biomarkers were screened and identified in the rat urine in this experiment. Compared with the normal group, the model group showed significant increases in the levels of 14 substances(P<0.05) and significant decreases in the levels of 11 substances(P<0.05). BYHWD was able to effectively reverse the trend of most endogenous biomarkers. Compared with the model group, BYHWD significantly down-regulated 13 biomarkers(P<0.05) and up-regulated 10 biomarkers(P<0.05). The metabolic products were mainly related to the biosynthesis of pantothenic acid and coenzyme A, tryptophan metabolism, retinol metabolism, and propionate metabolism. BYHWD has therapeutic effect on chronic inflammation induced by LPS, which may be related to its ability to improve the levels of endogenous metabolites, enhance the body's anti-inflammatory and antioxidant capabilities, and restore normal metabolic activity.

ABSTRACT

OBJECTIVE@#To explore the efficacy and survival of venetoclax based (VEN-based) regimen in the treatment of acute myeloid leukemia(AML).@*METHODS@#A retrospective study was conducted in patients who received VEN-based regimen and completed at least 1 course of efficacy evaluation at the The First Affiliated Hospital of Nanchang University from July 2019 to July 2022. The incidence of complete remission (CR)/CR with incomplete hematologic recovery (CRi) rate, objective remission rate(ORR) and survival of patients with different risk strati- fication and gene subtypes were analyzed.@*RESULTS@#A total of 79 patients were enrolled, including 43 patients with newly diagnosed unfit AML (unfit AML) and 36 relapsed/refractory AML (R/R AML). The median age of the patients was 62(14-83) years old. 36 out of 79 patients achieved CR/CRi and the ORR of the whole cohort was 64.6%. The CR/CRi rate of unfit AML patients was significantly higher than that of R/R AML patients (60.5% vs 27.8%, P=0.004). In unfit AML cohort, the patients with NPM1 and IDH1/2 mutations were benefited, 8 out of 9 patients ahcieved CR/CRi, 7/8 and 5/8 patients achieved minimal residual disease (MRD) negativity, respectively. Six out of 9 patients with TET2 mutation achieved CR/CRi, 3/6 patients achieved MRD negativity. In R/R AML cohort, 2 out of 3 patients with RUNX1 mutation achieved CR/CRi, without MRD negative, while the CR/CRi rate of patients with other gene mutations was lower than 40%. The median follow-up time was 10.1(95%CI: 8.6-11.6) months. In whole cohort, the median overall survival (mOS) time was 9.1 months and the relapse free survival (RFS) time was not reached. The mOS and RFS of unfit AML patients were significantly longer than those of R/R AML patients (14.1 vs 6.8 months, P=0.013; not reached vs 3.3 months, P=0.000). In unfit AML cohort, the mOS of patients with NPM1 or IDH1/2 mutations was not reached, while that of patients without NPM1 or IDH1/2 mutations was 8.0 months (P=0.009; P=0.022). Furthermore, the mOS of patients with TP53 mutaion was significantly shorter than that of patients without TP53 mutation (5.2 vs 14.1 months, P=0.049). In R/R AML cohort, there was no significant difference in mOS between patients with mutation in each gene subtype and those without gene mutation (P>0.05). All patients had hematology adverse reactions, 91.1% patients had AE grade≥3. The most common non-hematology adverse reactions was infection, with an incidence of 91.1%. VEN-based regimen was tolerable for AML patients.@*CONCLUSION@#VEN-based regimen can achieve a high response rate, especially in unfit AML with acceptable safety, and some patients can achieve MRD negative. It is also effective in NPM1-, IDH1/2-positive patients with long survival time.

ABSTRACT

OBJECTIVE@#To investigate the mechanism of drug reversing resistance of Agaricus blazei extract FA-2-b-β on T cell acute lymphoblastic leukemia (T-ALL) cell lines.@*METHODS@#Cell proliferation was detected by CCK-8 assay; the apoptosis, cell cycle mitochondrial membrane potential, and intracellular rhodamine accumulation were detected by flow cytometry, and apoptosis-related gene and protein expression were detected by qPCR and Western blot; the membrane surface protein MDR1 was observed by immunofluorescence microscopy.@*RESULTS@#Different concentrations of FA-2-b-β significantly inhibited proliferation and induced apoptosis of CCRF-CEM and CEM/C1 (P<0.05), and CCRF-CEM cell cycle were arrested at S phase, and CEM/C1 cells were arrested at G0/G1 phase. Western blot and qPCR results show that FA-2-b-β inhibited ABCB1、ABCG2、CTNNB、MYC and BCL-2 expression, but upregulated Bax expression. In addition, FA-2-b-β reversed the resistance characteristics of CEM/C1 drug-resistance cells, which decreased mitochondrial membrane potential, and significantly increased the intracellular rhodamine accumulation, and weakening of the expression of the membrane surface protein MDR1. With the Wnt/β-catenin inhibitor (ICG001), the process was further intensified.@*CONCLUSION@#Agaricus Blazei Extract FA-2-b-β inhibits cell proliferation, promotes apoptosis, regulates the cell cycle, reduces mitochondrial energy supply, and down-regulate MDR1 expression to reverse the resistance of CEM/C1, which all suggest it is through regulating the Wnt signaling pathway in T-ALL.

ABSTRACT

OBJECTIVE@#To investigate whether astragalus polysaccharides (APS) combined with berberine (BBR) can reduce high-fat diet (HFD)-induced obesity in mice.@*METHODS@#Except for normal mice, 32 HFD-induced obese mice were randomized into HFD, APS (1,000 mg/kg APS), BBR (200 mg/kg BBR), and APS plus BBR (1,000 mg/kg APS plus 200 mg/kg BBR) groups, respectively. After 6-week treatment (once daily by gavage), the obesity phenotype and pharmacodynamic effects were evaluated by histopathological examination of epididymal fat, liver, and colon using hematoxylin-eosin staining and serum biochemical analyses by an automated chemistry analyzer. The feces were collected at the 12 th week, and taxonomic and functional profiles of gut microbiota were analyzed by 16S ribosomal ribonucleic acid (16S rRNA) sequencing.@*RESULTS@#Compared with HFD group, the average body weight of APS plus BBR group was decreased (P<0.01), accompanied with the reduced fat accumulation, enhanced colonic integrity, insulin sensitivity and glucose homeostasis (P<0.05 or P<0.01). Importantly, APS combined with BBR treatment was more effective than APS or BBR alone in improving HFD-induced insulin resistance (P<0.05 or P<0.01). 16S rRNA sequence-based analysis of fecal samples demonstrated that APS combined with BBR treatment exhibited a better impact on HFD-induced gut microbiota dysbiosis, exclusively via the enriched abundances of Bacteroides, which corresponded to the large increase of predicted bacterial genes involved in carbohydrate metabolism.@*CONCLUSION@#APS combined with BBR may synergistically reduce obesity and modulate the gut microbiota in HFD-fed mice.

ABSTRACT

Wound healing is a dynamic process that involves a series of molecular and cellular events aimed at replacing devitalized and missing cellular components and/or tissue layers. Recently, extracellular vesicles (EVs), naturally cell-secreted lipid membrane-bound vesicles laden with biological cargos including proteins, lipids, and nucleic acids, have drawn wide attention due to their ability to promote wound healing and tissue regeneration. However, current exploitation of EVs as therapeutic agents is limited by their low isolation yields and tedious isolation processes. To circumvent these challenges, bioinspired cell-derived nanovesicles (CDNs) that mimic EVs were obtained by shearing mesenchymal stem cells (MSCs) through membranes with different pore sizes. Physical characterisations and high-throughput proteomics confirmed that MSC-CDNs mimicked MSC-EVs. Moreover, these MSC-CDNs were efficiently uptaken by human dermal fibroblasts and demonstrated a dose-dependent activation of MAPK signalling pathway, resulting in enhancement of cell proliferation, cell migration, secretion of growth factors and extracellular matrix proteins, which all promoted tissue regeneration. Of note, MSC-CDNs enhanced angiogenesis in human dermal microvascular endothelial cells in a 3D PEG-fibrin scaffold and animal model, accelerating wound healing in vitro and in vivo. These findings suggest that MSC-CDNs could replace both whole cells and EVs in promoting wound healing and tissue regeneration.

ABSTRACT

Objective:To investigate the efficacy of hemodiafiltration combined with hemoperfusion in the treatment of secondary hyperparathyroidism (SHPT) in patients undergoing maintenance hemodialysis (MHD).Methods:A total of 40 patients with SHPT undergoing MHD who received treatment at the Blood Purification Center of The First Affiliated Hospital of Anhui University of Science and Technology from February 2021 to March 2023 were included in this prospective cohort study. They were randomly divided into a control group and an observation group ( n = 20/group).The control group received a single high flux hemodialysis, while the observation group used a combination of hemodialysis filtration and hemoperfusion for 3 months. In both groups, the changes in hemoglobin, blood urea nitrogen, serum creatinine, serum calcium, serum phosphorus,and parathyroid hormone levels were compared before and after dialysis. Results:After dialysis, the hemoglobin level in the observation group was (119.45 ± 5.27) g/L, which was significantly higher than (106.30 ± 6.52) g/L in the control group ( t = -7.02, P < 0.001). The serum phosphorus level in the observation group was (1.18 ± 0.17) mmol/L, which was significantly lower than (1.52 ± 0.22) mmol/L in the control group ( t = 5.49, P < 0.001). The parathyroid hormone level in the observation group was (122.14 ± 40.57) ng/L, which was significantly lower than (168.78 ± 78.27) ng/L in the control group ( t = 2.39, P = 0.023). Conclusion:Hemodiafiltration combined with hemoperfusion can reduce clinical symptoms, increase hemoglobin level, and reduce phosphorus and parathyroid hormone levels in patients with SHPT undergoing MHD, which deserves clinical promotion.

The diagnosis and treatment process conformed to the cervical cancer diagnosis and treatment norms, and there were a total of 594 patients with no previous cervical surgery history,including 463 cases in the premenopausal group and 131 cases in the menopausal group, and the age, contact bleeding, gynecological examination, HR-HPV, liquid-based thin layer cytology, colposcopy and biopsy results, and post-cervical cone surgery pathological results were compared and analyzed, and multivariate Logistic regression analysis was carried out for statistically different factors to identify the clinical pathological characteristics of postmenopausal HSIL patients. T-test was used for the comparison between measurement data groups with normal distribution, and rank sum test was used for the comparison between measurement data groups with non normal distribution. Counting data use χ 2 test or Fisher exact probability method. Logistic regression analysis was used in multivariate analysis. Results:There was no significant difference in the positive rate of contact bleeding (12.98%(17/131)) and HR-HPV (77.86%(102/131)) between postmenopausal group and non postmenopausal group (11.45%(53/463) and 80.56% (373/463))(χ 2 values were 0.23 and 0.46; P values were 0.632 and 0.496). The proportion of cervical columnar epithelium displacement (43.51% (57/131)) and abnormal liquid-based thin-layer cytology (87.79%(115/131)) in the postmenopausal group were lower than those in the non postmenopausal group (64.36%(298/463) and 93.74%(434/463)). There was significant difference between the two groups (χ 2 values were 18.46 and 5.16; P values were < 0.001 and 0.023). The positive rate of ECC (62.60%(82/131)), cervical type Ⅲ transformation area (73.28%(96/131)), the proportion of pathological upgrading after conization (9.92%(13/131)) and the positive rate of cutting edge after conization (24.43%(32/131)) in menopausal group were higher than those in non menopausal patients (46.22%(214/463), 26.78%(124/463), 1.73%(8/463) and 5.40%(25/463)). There were significant differences between the two groups (χ 2 values were 10.95, 94.68, 20.11 and 42.62; P values were 0.001, <0.001, <0.001 and <0.001). Multivariate Logistic regression analysis showed a high proportion of cervical type Ⅲ transformational zones ( OR=6.569, 95% CI 4.130-10.446), high ECC positivity ( OR=1.978, 95% CI 1.250-3.128), the positive rate of cone incision margins was high ( OR=4.581, 95% CI 2.386-8.794), the proportion of pathological escalation after cone surgery ( OR=4.612, 95% CI 1.557-13.668) and the proportion of smooth cervical appearance were high ( OR=0.464, 95% CI 0.294-0.731), which was the clinicopathological feature of postmenopausal HSIL ( P values were <0.001, 0.004, <0.001, 0.006 and 0.001). Conclusion:There were differences in HSIL in patients before and after menopause, clinical symptoms and screening manifestations were atypical, and lesions are easy to involve the cervical canal, the positive rate of the cut margin after coneectomy was high, and the proportion of pathological escalation was high, so more aggressive intervention should be taken for women diagnosed with precancerous cervical lesions after menopause

ABSTRACT

Objective:To investigate the application value of intravoxel incoherent motion (IVIM) imaging in preoperative evaluating perineural invasion (PNI) of esophageal squamous cell carcinoma (ESCC).Methods:The prospective study was conducted. The clinicopathological data of 63 ESCC patients who underwent IVIM imaging before surgery in the Affiliated Cancer Hospital of Zhengzhou University & Henan Cancer Hospital from January 2016 to April 2019 were selected. Patients underwent routine magnetic resonance imaging scan and IVIM sequence examination. The apparent diffusion coefficient (ADC), true diffusion coefficient (D), pseudodiffusion coefficient (D*) and pseudodiffusion fraction (f) values were measured. Observation indicators: (1) situations of enrolled patients; (2) IVIM examination of PNI of ESCC and its diagnostic efficiency. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was analyzed using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. The interclass correlation coefficient (ICC) was used to evaluate cosistency of results. The receiver operating characrteristic curve was used to evaluate diagnostic efficiency. Results:(1) Situations of enrolled patients. A total of 63 patients were selected for eligibility. There were 41 males and 22 females, aged 60(range, 43?74)years. Of the 63 ESCC patients, 17 cases had PNI and 46 cases had no PNI. Cases with well differentiated tumor, moderate differentiated tumor or low differentiated tumor, cases in stage T1, T2, T3, T4 of infiltra-tion depth, cases with or without lymph node metastasis were 0, 6, 11, 0, 3, 13, 1, 15, 2 in patients with PNI, versus 6, 24, 16, 1, 22, 23, 0, 12, 34 in patients without PNI, showing significant differences between them ( Z=?2.32, ?2.49, χ2=19.58, P<0.05). (2) IVIM examination of PNI of ESCC and its diagnostic efficiency. The ADC, D, D*, f values were (2.21±0.33)×10 ?3 mm 2/s, (1.46±0.31)×10 ?3 mm 2/s, 32.50 (15.55,46.75)×10 ?3 mm 2/s, (0.34±0.09)×10 ?3 mm 2/s in patients with PNI, versus (2.45±0.45)×10 ?3 mm 2/s, (1.72±0.38)×10 ?3 mm 2/s, 34.85(23.43,51.20)×10 ?3 mm 2/s, (0.42±0.13)×10 ?3 mm 2/s in patients without PNI, showing significant differences in the ADC, D and f values between them ( t=?2.03, ?2.52, ?2.34, P<0.05) and no significant difference in the D* value between them ( Z=?0.84, P>0.05). The cosistency of ADC, D, D* and f values in the 63 ESCC patients measured by 2 radiologists was good, with the ICC as 0.96, 0.92, 0.89 and 0.95. The receiver operating characrteristic curve demons-trated the best cut-off value of ADC, D and f values were 2.50×10 ?3 mm 2/s, 1.68×10 ?3 mm 2/s and 0.41, with the areas under the curve as 0.67 (95% confidence interval as 0.54?0.79), 0.70 (95% confidence interval as 0.58?0.81) and 0.69 (95% confidence interval as 0.57?0.80), respectively. The combina-tion of D and f value for diagnosing PNI of ESCC had the area under the curve as 0.74 (95% confidence interval as 0.62?0.84), with the cut-off value as 0.20, sensitivity and specificity as 94.1% and 56.5%. Conclusions:IVIM parameters D and f values can evaluate and predict the PNI of ESCC preopera-tively. The combination of D and f values can further improve the diagnostic efficiency.

ABSTRACT

PURPOSE@#COVID-19 is also referred to as a typical viral septic pulmonary infection by 2019-nCoV. However, little is known regarding its characteristics in terms of systemic inflammation and organ injury, especially compared with classical bacterial sepsis. This article aims to investigate the clinical characteristics and prognosis between COVID-19-associated sepsis and classic bacterial-induced sepsis.@*METHODS@#In this retrospective cohort study, septic patients with COVID-19 in the intensive care unit (ICU) of a government-designed therapy center in Shenzhen, China between January 14, 2020 and March 10, 2020, and septic patients induced by carbapenem-resistant klebsiella pneumonia (CrKP) admitted to the ICU of the Second People's Hospital of Shenzhen, China between January 1, 2014 and October 30, 2019 were enrolled. Demographic and clinical parameters including comorbidities, critical illness scores, treatment, and laboratory data, as well as prognosis were compared between the two groups. Risk factors for mortality and survival rate were analyzed using multivariable logistic regression and survival curve, respectively.@*RESULTS@#A total of 107 patients with COVID-19 and 63 patients with CrKP were enrolled. A direct comparison between the two groups demonstrated more serious degrees of primary lung injury following 2019-nCoV infection (indicated by lower PaO@*CONCLUSION@#Critical COVID-19 shares clinical characteristics with classical bacterial sepsis, but the degree of systemic inflammatory response, secondary organ damage and mortality rate are less severe. However, following 2019-nCoV infection, the level of immunosuppression may be increased and thus induce in more death at the later stage of patients' hospitalstay.
