ABSTRACT

ABSTRACT Introduction: Vitamin E supplementation may protect against exercise-induced muscle damage (EIMD) through possible inhibition of free radical formation and cell membrane stabilization. However, there is no systematic review of this topic. This fact maintains academic stalemates that may have a resolution. Objective: This systematic review with meta-analysis aims to provide a comprehensive literature review on the hypothesis of the benefit of vitamin E supplementation on oxidative stress and muscle damage induced by aerobic exercise. Methods: A random-effects model was used, weighted mean difference (WMD) and 95% confidence interval (CI) were applied to estimate the overall effect. Results: The results revealed a significant effect of vitamin E supplementation on reducing creatine kinase (CK) and lactate dehydrogenase (LDH). In addition, a subgroup analysis resulted in a significant decrease in CK concentrations in trials with immediate and <24 hours post-exercise CK measurement; <1000 at daily vitamin E intake; ≤1 at weekly intake; 1 at six weeks and >6 weeks experimental duration, studies on aerobic exercise and training were part of the crossover study. Conclusion: Vitamin E can be seen as a priority agent for recovery from muscle damage. Evidence Level II; Therapeutic Studies - Investigating the results.

ABSTRACT

ObjectiveTo explore the potential mechanism of Polygonati Rhizoma on the treatment of osteoporosis (OP) based on network pharmacology and molecular docking method and to verify the mechanism by experiments. MethodThe main active ingredients and corresponding targets of Polygonati Rhizoma were screened out from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) 2.3 by conditional searching. The treatment targets were obtained from the genes related to OP and DisGeNET 7.0. The potential target genes of Polygonati Rhizoma for treating OP were obtained by the crossing of the corresponding targets and the treatment targets. Cytoscape 3.7.1 was used to construct the “Polygonati Rhizoma-active ingredient-potential target” network. The protein-protein interaction (PPI) analysis was carried out by STRING 11.0, and the PPI network was constructed. Metascape 3.5 was used to conduct Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of the key targets. The core ingredients and key targets of Polygonati Rhizoma were selected for molecular docking by AutoDock Vina 1.1.2. Finally, the effect of β-sitosterol on osteogenic differentiation of MC3T3-E1 cells in rats was observed. ResultTwelve active ingredients and 32 potential targets of Polygonati Rhizoma for OP treatment were screened out. Six active ingredients including baicalein and β-sitosterol and key targets including protein kinase 1 (Akt1), tumor suppressor p53 (TP53), vascular endothelial growth factorA (VEGFA), proto-oncogene Jun (JUN), matrix metalloproteinase-9 (MMP-9), and proto-oncogene c-Fos (FOS) were obtained by Cytoscape 3.7.1 topological analysis. A total of 995 GO entries and 181 signaling pathways involving the response to reactive oxygen species and regulations of growth were obtained from GO and KEGG enrichment analyses. The results of molecular docking showed that the core active ingredients possessed good binding activities with the respective key targets. The results of cell experiments showed that β-sitosterol promoted the osteogenic differentiation at the concentration of 2.5 μmol·L-1 and 5 μmol·L-1. ConclusionPolygonati Rhizoma had the therapeutic effect on treating OP by regulating inflammation, oxidative stress, apoptosis, and metabolism. The β-sitosterol significantly promoted the osteogenic differentiation of MC3T3-E1 cells.

ABSTRACT

AIM:To evaluate the underlying aetiology and clinical characteristics of retinal detachment(RD)in school-age pediatric monocular RD.METHODS:Patients with RD and contralateral blind(monocular RD)aged 7-14 years, from November 2015 to May 2021 in our hospital were retrospectively reviewed. Demographic characteristics and etiology of RD, clinical type, surgical modality, type of intraocular tamponade, pre-and postoperative visual and anatomical outcomes were recorded and evaluated.RESULTS: There were 27 children(27 eyes)with monocular RD at least 6mo follow-up. The average age at presentation was 10.63±2.30 years. Familial exudative vitreoretinopathy(FEVR)(11/27, 41%), postoperative congenital glaucoma(6/27, 22%)and Stickler syndrome(3/27, 11%)were main underlying etiologies. Among them, rhegmatogenous retinal detachment(RRD)comprised 78%(21/27)of the patients, of which 81% patients(17/21)had proliferative vitreoretinopathy(PVR)C3 or worse. Pars plana vitrectomy(PPV)was done in 85%(23/27)of the patients, of which 83%(19/23)received silicone oil tamponade. Best corrected visual acuity(BCVA, LogMAR)worse than 1.7 was seen in 78%(21/27)of the patients at final visit, and 82%(22/27)had reattached retina, but 41%(11/27)of the patients remained status of silicone oil tamponade at last visit.CONCLUSION:School-age pediatric monocular RD is often associated with underlying congenital or hereditary conditions, and often presented with severe RD and severe PVR reaction which needed vitrectomy combined with silicon oil tamponade, and with poor visual and anatomical short-term prognosis.

ABSTRACT

With the aging of population and the development of social economy, the incidence of chronic wounds is increasing day by day, while the incidence of burns and trauma remains at a high level, making wound repair an increasingly concerned area in clinical practice. Thymosin β4 is a naturally occurring small molecule protein in vivo, which is widely distributed in a variety of body fluids and cells, especially in platelets. Thymosin β4 has biological activities of promoting angiogenesis, anti-inflammation, anti-apoptosis, and anti-fibrosis, and has many important functions in wound repair. Thymosin β4 has been observed to promote the healing of various wounds, such as burns, diabetic ulcers, pressure ulcers. This paper will review the molecular structure, mechanism of wound healing promotion, pharmacokinetics, and clinical application of thymosin β4, aiming to introduce its potential in wound treatment and the shortcomings of current researches.

ABSTRACT

The damage of sweat glands in patients with extensive deep burns results in the loss of thermoregulation, which seriously affects the quality of life of patients. At present, there are many researches on the repair of sweat gland function, but the mechanism of human sweat gland development has not been fully clarified. More and more studies have shown that the cascaded pathways of Wnt/β-catenin, ecto- dysplasin A/ectodysplasin A receptor/nuclear factor-κB, sonic hedgehog, and forkhead box transcription factor jointly affect the development of sweat glands, and it has been reported that the cascaded signaling pathways can be used to achieve the reconstruction of sweat adenoid cells in vitro. This article reviews the signaling pathways that affect the development of sweat glands and their involvement in the reconstruction of sweat adenoid cells in vitro.

ABSTRACT

Objective: To explore the value of cerebral hypoxic-ischemic injury markers in the early diagnosis of sepsis associated encephalopathy (SAE) in burn patients with sepsis. Methods: A retrospective case series study was conducted. From October 2018 to May 2021, 41 burn patients with sepsis who were admitted to Zhengzhou First People's Hospital met the inclusion criteria, including 23 males and 18 females, aged 18-65 (35±3) years. According to whether SAE occurred during hospitalization, the patients were divided into SAE group (21 cases) and non-SAE group (20 cases). The gender, age, deep partial-thickness burn area, full-thickness burn area, and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores of patients were compared between the two groups. The serum levels of central nervous system specific protein S100β and neuron specific enolase (NSE) at 12, 24, and 48 h after sepsis diagnosis (hereinafter referred to as after diagnosis), the serum levels of interleukin-6 (IL-6), IL-10, tumor necrosis factor α (TNF-α), Tau protein, adrenocorticotropic hormone (ACTH), and cortisol at 12, 24, 48, 72, 120, and 168 h after diagnosis, and the mean blood flow velocity of middle cerebral artery (VmMCA), pulsatility index, and cerebral blood flow index (CBFi) on 1, 3, and 7 d after diagnosis of patients in the two groups were counted. Data were statistically analyzed with chi-square test, analysis of variance for repeated measurement, independent sample t test, and Bonferroni correction. The independent variables to predict the occurrence of SAE was screened by multi-factor logistic regression analysis. The receiver operating characteristic (ROC) curve was drawn for predicting the occurrence of SAE in burn patients with sepsis, and the area under the curve (AUC), the best threshold, and the sensitivity and specificity under the best threshold were calculated. Results: The gender, age, deep partial-thickness burn area, full-thickness burn area, and APACHE Ⅱ score of patients in the two groups were all similar (χ2=0.02, with t values of 0.71, 1.59, 0.91, and 1.07, respectively, P>0.05). At 12, 24, and 48 h after diagnosis, the serum levels of S100β and NSE of patients in SAE group were all significantly higher than those in non-SAE group (with t values of 37.74, 77.84, 44.16, 22.51, 38.76, and 29.31, respectively, P<0.01). At 12, 24, 48, 72, 120, and 168 h after diagnosis, the serum levels of IL-10, Tau protein, and ACTH of patients in SAE group were all significantly higher than those in non-SAE group (with t values of 10.68, 13.50, 10.59, 8.09, 7.17, 4.71, 5.51, 3.20, 3.61, 3.58, 3.28, 4.21, 5.91, 5.66, 4.98, 4.69, 4.78, and 2.97, respectively, P<0.01). At 12, 24, 48, 72, and 120 h after diagnosis, the serum levels of IL-6 and TNF-α of patients in SAE group were all significantly higher than those in non-SAE group (with t values of 8.56, 7.32, 2.08, 2.53, 3.37, 4.44, 5.36, 5.35, 6.85, and 5.15, respectively, P<0.05 or P<0.01). At 12, 24, and 48 h after diagnosis, the serum level of cortisol of patients in SAE group was significantly higher than that in non-SAE group (with t values of 5.44, 5.46, and 3.55, respectively, P<0.01). On 1 d after diagnosis, the VmMCA and CBFi of patients in SAE group were significantly lower than those in non-SAE group (with t values of 2.94 and 2.67, respectively, P<0.05). On 1, 3, and 7 d after diagnosis, the pulsatile index of patients in SAE group was significantly higher than that in non-SAE group (with t values of 2.56, 3.20, and 3.12, respectively, P<0.05 or P<0.01). Serum IL-6 at 12 h after diagnosis, serum Tau protein at 24 h after diagnosis, serum ACTH at 24 h after diagnosis, and serum cortisol at 24 h after diagnosis were the independent risk factors for SAE complicated in burn patients with sepsis (with odds ratios of 2.42, 1.38, 4.29, and 4.19, 95% confidence interval of 1.76-3.82, 1.06-2.45, 1.37-6.68, and 3.32-8.79, respectively, P<0.01). For 41 burn patients with sepsis, the AUC of ROC of serum IL-6 at 12 h after diagnosis for predicting SAE was 0.92 (95% confidence interval was 0.84-1.00), the best threshold was 157 pg/mL, the sensitivity was 81%, and the specificity was 89%. The AUC of ROC of serum Tau protein at 24 h after diagnosis for predicting SAE was 0.92 (95% confidence interval was 0.82-1.00), the best threshold was 6.4 pg/mL, the sensitivity was 97%, and the specificity was 99%. The AUC of ROC of serum ACTH at 24 h after diagnosis for predicting SAE was 0.96 (95% confidence interval was 0.89-1.00), the best threshold was 14.7 pg/mL, the sensitivity was 90%, and the specificity was 94%. The AUC of ROC of serum cortisol at 24 h after diagnosis for predicting SAE was 0.93 (95% confidence interval was 0.86-1.00), the best threshold was 89 nmol/L, the sensitivity was 94%, and the specificity was 97%. Conclusions: Serum Tau protein, ACTH, and cortisol have high clinical diagnostic value for SAE complicated in burn patients with sepsis.

ABSTRACT

Objective: To investigate the effects of continuous goal-directed analgesia on fluid resuscitation during shock stage in patients with massive burns, providing a basis for rational optimization of analgesia protocols in patients with burn shock. Methods: A retrospective case series study was conducted. One hundred and thirty-six patients with massive burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital from January 2015 to December 2020, and the patients were divided into continuous analgesia (CA) group (68 cases,with average age of 44 years old) and intermittent analgesia (IA) group (68 cases,with average age of 45 years old) according to whether sufentanil injection was continuously used for intravenous analgesia during the shock stage. The patients in the 2 groups were predominantly male. Before and at 72 h of treatment, the severity of disease and trauma pain of patients in the 2 groups were scored by the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and the visual analogue scale (VAS). Hematocrit, heart rate, mean arterial pressure (MAP), central venous pressure (CVP), oxygen saturation in central venous blood (ScvO2), rehydration coefficient, blood lactate value, hourly urine output, and the adverse reactions such as hypotension, nausea, vomiting, dizziness, skeletal muscle tonicity, respiratory depression, bradycardia, pruritus, and drug addiction of patients in the 2 groups during the treatment were recorded at the 1st, 2nd, and 3rd 24 h post-injury. Data were statistically analyzed with analysis of variance for repeated measurement, paired or independent sample t test, Bonferroni correction,chi-square test and Mann-Whitney U test. Results: Before treatment, APACHE Ⅱ and VAS scores of patients in the 2 groups were close (with t values of -0.67 and 0.32, respectively, P>0.05); At 72 h of treatment, APACHE Ⅱ and VAS scores of patients in CA group were 8.5±2.2 and 2.5±1.6, both of which were significantly lower than (15.2±3.0) and (7.9±2.0) of patients in IA group, respectively (with t values of -14.94 and -17.46, respectively, P<0.01). Compared with the pre-treatment period, the APACHE Ⅱ and VAS scores of patients in IA group decreased significantly at 72 h of treatment (with t values of 11.35 and 30.59, respectively, P<0.01); the changes in APACHE Ⅱ and VAS scores of patients at 72 h of treatment in comparison with those of patients before treatment in CA group were all similar to those of patients in IA group (with t values of 4.00 and 4.82, respectively, P<0.01). Compared with those of patients in IA group, there were no significant changes in CVP, hematocrit, heart rate, ScvO2, and MAP of patients in CA group at all three 24 h post-injury (with t values of <0.01, 0.12, 2.10, 1.55, 0.03; 0.13, 0.22, <0.01, 0.17, 0.49; 0.63, 0.06, 0.04, 2.79, and 2.33, respectively, P>0.05). Compared with those of patients in IA group at the 1st 24 h post-injury, CVP, ScvO2 and MAP of patients were significantly higher at the 2nd and 3rd 24 h post-injury (with t values of -10.10, -9.31, -8.89; -10.81, -4.65, and -9.43, respectively, P<0.01), and the heart rate of patients was significantly lower at the 2nd and 3rd 24 h post-injury (with t values of 7.53 and 7.78, respectively, P<0.01), and the hematocrit of patients decreased significantly only at the 3rd 24 h post-injury (t=15.55, P<0.01); the changes of CVP, ScvO2, MAP and heart rate of patients at the 2nd and the 3rd 24 h post-injury, and HCT of patients at the 3rd 24 h post-injury, in comparison with those of patients at the 1st 24 h post-injury in CA group were similar to those of patients in IA group (with t values of -12.25, -10.24, -8.99, 9.42, -8.83, -7.53, -11.57, 10.44, and 12.91, respectively, P<0.01). Compared with those of patients in IA group, the rehydration coefficient of patients in CA group was significantly higher only at the 3rd 24 h post-injury (t=5.60, P<0.05), blood lactate value of patients in CA group was significantly lower at the 1st and 2nd 24 h post-injury (with t values of 4.32 and 14.52, respectively, P<0.05 or P<0.01), the hourly urine output of patients in CA group increased significantly at the 1st, 2nd, and 3rd 24 h post-injury (with t values of 24.65, 13.12, and 5.63, respectively, P<0.05 or P<0.01). Compared with the those of patients at the 1st 24 h post-injury, the rehydration coefficient of patients in IA group decreased significantly at the 2nd and the 3rd 24 h post-injury (with t values of 33.98 and 36.91, respectively, P<0.01), the blood lactate values of patients in IA group decreased significantly at the 2nd and the 3rd 24 h post-injury (with t values of 8.20 and 11.68, respectively, P<0.01), and the hourly urine output of patients in IA group was significantly increased at the 2nd and the 3rd 24 h post-injury (with t values of -3.52 and -5.92, respectively, P<0.01); the changes of rehydration coefficients and blood lactate values of patients at the 2nd and the 3rd 24 h post-injury in comparison with those of patients at the 1st 24 h post-injury in CA group were similar to those of patients in IA group (with t values of 35.64, 33.64, 9.86, and 12.56, respectively, P<0.01), but hourly urine output of patients in CA group increased significantly only at the 3rd 24 h compared with that of patients at the 1st 24 h post-injury (t=-3.07, P<0.01). Adverse reactions such as hypotension, nausea, vomiting, dizziness, bradycardia, and pruritus occurred rarely in patients of the 2 groups, and none of the patients had skeletal muscle tonicity, respiratory depression, or drug addiction. The incidence of adverse reactions of patients in CA group was similar to that in IA group (χ2=0.08, P>0.05). Conclusions: Continuous goal-directed analgesia can effectively relieve pain and improve vital signs of patients with large burns. Meanwhile it has little impact on volume load, which can assist in correcting ischemia and hypoxia during the shock period and help patients get through the shock period smoothly.

ABSTRACT

Objective: To quantitatively evaluate myocardial work in patients with hepatitis B cirrhosis by using left ventricular pressure-strain loop. Methods: 70 cases with hepatitis B cirrhosis who were hospitalized in Henan Provincial People's Hospital from March to December 2020 were selected as the study group. Patients were divided into three subgroups according to the Child-Pugh score of liver cirrhosis (Child-Pugh class A, B, and C groups: 25, 25, and 20 patients, respectively). At the same time, 25 healthy volunteers were included as the control group. Global longitudinal strain (GLS), global myocardial work index (GWI), global work efficiency (GWE), global constructive work (GCW), and global wasted work (GWW) were obtained by applying pressure-strain loops. The differences were analyzed and compared among the four groups parameters. Results: Compared with the control group, the Child-Pugh class A group had decreased GLS, while Child-Pugh class B and C had decreased GLS, GWI, GWE, GCW, and increased GWW, and the differences were statistically significant (P<0.05). Compared with Child-Pugh class A group, Child-Pugh class B group had decreased GLS, GWE, and increased GWW, while Child-Pugh class C group had decreased GLS,GWI, GWE, GCW, and increased GWW, and the differences were statistically significant (P<0.05). Compared with Child-Pugh class B group, Child-Pugh class C group had decreased GLS, GWI, GWE, GCW, and increased GWW, and the differences were statistically significant (P<0.05). Conclusion: The pressure-strain loop can detect early myocardial dysfunction, and has a certain value in the diagnosis, treatment and prognosis evaluation of myocardial function changes in patients with hepatitis B cirrhosis.

ABSTRACT

Aortoiliac occlusive disease (AIOD) refers to the stenosis and occlusion of the distal abdominal aorta and(or) bifurcation of the aortoiliac artery,which is mainly caused by atherosclerosis,leading to pelvic and lower limb ischemia.Open surgery has always been the main treatment for complex AIOD.However,in recent years,with the development of endovascular surgery technologies and medical instruments,its treatment concept has been greatly changed.More and more clinical evidence has proved that the long-term efficacy of endovascular therapy is not inferior to that of traditional open surgery,so minimally invasive endovascular therapy has become the preferred treatment for AIOD.

ABSTRACT

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

Objective:To explore the method of sequential sector scan with 2D ultrasound through oral fissure (SSTOF) and its utilization in the cleft palate screening.Methods:Based on features of oral anatomy and ultrasonic beam, SSTOF was designed to screen cleft palate and the accuracy had been verified using specimens of aborted fetuses. This study recruited 7 154 women with singleton pregnancy who were screened for fetal malformations during 20-28 gestational weeks in the First Affiliated Hospital of Anhui Medical University from May 2020 to October 2020. In medical addition to routine screening, these subjects also underwent SSTOF to further verify its feasibility and imaging performance. Follow-up was performed by telephone and medical record review.Results:Clear images of the upper palate were acquired in five specimens of induced fetuses using SSTOF. Except for 56 cases lost to follow-up, a total of 7 098 fetuses were finally enrolled, of which 6 885 acquired satisfactory images using SSTOF, 213 did not due to inappropriate position, with a success image rate of 97%. SSTOF found cleft palate in 31cases, which were all confirmed after birth or induction, noting an accuracy rate of 100%.Conclusion:Sequential sector scan through oral fissure has a high clinical value on cleft palate screening in the second trimester with advantages of clear image, easy operation, and access to section views.

ABSTRACT

Folate receptor(FR)overexpression occurs in a variety of cancers,including pancreatic cancer.In addi-tion,enhanced macropinocytosis exists in K-Ras mutant pancreatic cancer.Furthermore,the occurrence of intensive desmoplasia causes a hypoxic microenvironment in pancreatic cancer.In this study,a novel FR-directed,macropinocytosis-enhanced,and highly cytotoxic bioconjugate folate(F)-human serum albumin(HSA)-apoprotein of lidamycin(LDP)-active enediyne(AE)derived from lidamycin was designed and prepared.F-HSA-LDP-AE consisted of four moieties:F,HSA,LDP,and AE.F-HSA-LDP presented high binding efficiency with the FR and pancreatic cancer cells.Its uptake in wild-type cells was more extensive than in K-Ras mutant-type cells.By in vivo optical imaging,F-HSA-LDP displayed prominent tumor-specific biodistribution in pancreatic cancer xenograft-bearing mice,showing clear and lasting tumor localization for 360 h.In the MTT assay,F-HSA-LDP-AE demonstrated potent cytotoxicity in three types of pancreatic cancer cell lines.It also induced apoptosis and caused G2/M cell cycle arrest.F-HSA-LDP-AE markedly suppressed the tumor growth of AsPc-1 pancreatic cancer xenografts in athymic mice.At well-tolerated doses of 0.5 and 1 mg/kg,(i.v.,twice),the inhibition rates were 91.2%and 94.8%,respectively(P<0.01).The results of this study indicate that the F-HSA-LDP multi-functional bioconjugate might be effective for treating K-Ras mutant pancreatic cancer.

ABSTRACT

The National Medical Products Administration has authorized sodium oligomannate for treating mild-to-moderate Alzheimer's disease.In this study,an LC-MS/MS method was developed and validated to quantitate sodium oligomannate in different biomatrices.The plasma pharmacokinetics,tissue distri-bution,and excretion of sodium oligomannate in Sprague-Dawley rats and beagle dogs were system-atically investigated.Despite its complicated structural composition,the absorption,distribution,metabolism,and excretion profiles of the oligosaccharides in sodium oligomannate of different sizes and terminal derivatives were indiscriminate.Sodium oligomannate mainly crossed the gastrointestinal epithelium through paracellular transport following oral administration,with very low oral bioavail-ability in rats(0.6%-1.6%)and dogs(4.5%-9.3%).Absorbed sodium oligomannate mainly resided in circulating body fluids in free form with minimal distribution into erythrocytes and major tissues.So-dium oligomannate could penetrate the blood-cerebrospinal fluid(CSF)barrier of rats,showing a con-stant area under the concentration-time curve ratio(CSF/plasma)of approximately 5%.The cumulative urinary excretion of sodium oligomannate was commensurate with its oral bioavailability,supporting that excretion was predominantly renal,whereas no obvious biliary secretion was observed following a single oral dose to bile duct-cannulated rats.Moreover,only 33.7%(male)and 26.3%(female)of the oral dose were recovered in the rat excreta within 96 h following a single oral administration,suggesting that the intestinal flora may have ingested a portion of unabsorbed sodium oligomannate as a nutrient.

ABSTRACT

Objective:To investigate the effects of inhibition of Wnt/ β-catenin signaling pathway on paraquat (PQ)-induced transition of human lung fibroblast cell line MRC-5 and related molecular mechanisms.Methods:The MRC-5 cells were divided into three groups. Control group: without drug treatment; PQ group: the cells were treated by PQ (50 μmol/L) for 72 hours to establish cell transition model; PQ+DKK1 group: the cells were treated with PQ (50 μmol/L) and DKK1 (10 ng/mL) for 72 hours. Then, the cells were collected, and the transition related signatures including α-SMA, Vimentin and Collagen I were detected by immunofluorescence and Western blot (WB); Meanwhile, the expression levels of Wnt pathway-related molecules including β-catenin, Cyclin D1 and WISP1 were determined by WB, immunofluorescence and real-time fluorescence quantitative PCR (RT-PCR) during the transition; In addition, the inhibitor of Wnt/β-catenin pathway Dickkopf-1 (DKK1) was applied to block the signaling. Then the expression changes of β-catenin, cyclin D1 and WISP1 were detected by WB to verify the inhibitory effect, and the transition marker molecules including α-SMA, Vimentin and Collagen I were also determined by WB.Results:After 72 hours, compared with the Control group, the expression levels of α-SMA, Vimentin and Collagen I of MRC-5 cells in PQ group were increased significantly ( P<0.05); The expression levels of β-catenin, Cyclin D1 and WISP1 of MRC-5 cells in PQ group were significantly up-regulated ( P<0.05); DKK1 could inhibit the high expression of α-SMA, Vimentin and Collagen I of MRC-5 cells during PQ-induced transition ( P<0.05). Conclusions:DKK1 could inhibit PQ-induced transition of lung fibroblasts by interference with Wnt/β-catenin signaling, which was expected to further inhibit pulmonary fibrosis caused by PQ.

ABSTRACT

Aconiti Kusnezoffii Radix Cocta is one of the most commonly used medicinal materials in Mongolian medicine. Due to the strong toxicity of Aconiti Kusnezoffii Radix Cocta, Mongolian medicine often uses Chebulae Fructus, Glycyrrhizae Radix et Rhizoma to reduce the toxicity, so as to ensure the curative effect of Aconiti Kusnezoffii Radix Cocta while ensuring its clinical curative effect, but the mechanism is not clear. The aim of this study was to investigate the effects of Chebulae Fructus, Glycyrrhizae Radix et Rhizoma and Aconiti Kusnezoffii Radix Cocta on the mRNA transcription and protein translation of cytochrome P450(CYP450) in the liver of normal rats. Male SD rats were randomly divided into negative control(NC) group, phenobarbital(PB) group(0.08 g·kg~(-1)·d~(-1)), Chebulae Fructus group(0.254 2 g·kg~(-1)·d~(-1)), Glycyrrhizae Radix et Rhizoma group(0.254 2 g·kg~(-1)·d~(-1)), Aconiti Kusnezoffii Radix Cocta group(0.254 2 g·kg~(-1)·d~(-1))and compatibility group(0.254 2 g·kg~(-1)·d~(-1),taking Aconiti Kusnezoffii Radix Cocta as the standard). After continuous administration for 8 days, the activities of total bile acid(TBA), alkaline phosphatase(ALP), amino-transferase(ALT) and aspartate aminotransferase(AST)in serum were detected, the pathological changes of liver tissue were observed, and the mRNA and protein expression levels of CYP1 A2, CYP2 C11 and CYP3 A1 were observed. Compared with the NC group, the serum ALP, ALT and AST activities in the Aconiti Kusnezoffii Radix Cocta group were significantly increased, and the ALP, ALT and AST activities were decreased after compatibility. At the same time, compatibility could reduce the liver injury caused by Aconiti Kusnezoffii Radix Cocta. The results showed that Aconiti Kusnezoffii Radix Cocta could inhibit the expression of CYP1 A2, CYP2 C11 and CYP3 A1, and could up-regulate the expression of CYP1 A2, CYP2 C11 and CYP3 A1 when combined with Chebulae Fructus and Glycyrrhizae Radix et Rhizoma. The level of translation was consistent with that of transcription. The compatibility of Chebulae Fructus and Glycyrrhizae Radix et Rhizoma with Aconiti Kusnezoffii Radix Cocta could up-regulate the expression of CYP450 enzyme, reduce the accumulation time of aconitine in vivo, and play a role in reducing toxicity, and this effect may start from gene transcription.

ABSTRACT

Objective: To investigate the repair effect and JNK/NF-κB,SOX9 mechanisms of vibration exercise with different frequencies on articular cartilage in rats with early knee osteoarthritis. Methods: Forty-eight adult male SD rats were randomly divided into six groups(n=8):model control group(MC),high frequency vibration group 1 (GP1,60 Hz),high frequency vibration 2 group (GP2,40 Hz),medium frequency vibration group (ZP,20 Hz),minor frequency group(DP,10 Hz)and normal control group(NC). Except for NC group,the rats in each group were made into early knee osteoarthritis model after six weeks of knee joint cavity injection of papain solution and 2% mixture l-cysteine on the 1st,4 th and 7th day. Each exercise group was subjected vibration to 40 minutes a day with amplitude of 2~5 mm and 5 days a week. Four weeks later, the articular cartilage of the lateral femoral condyle of the both back leg knee joints were detected by HE staining,serine O staining and Mankin scores for morphological observation. The expression levels of JNK,NF-κB p65 and Sox9 mRNA in articular cartilage of the medial femoral condyle were detected by RT-qPCR,and the protein expressions of JNK,NF-κB p65 and Sox9 were detected by Western blot. Results: Compared with the NC group,the Mankin score in other groups was significantly higher (P<0.01). Compared with the MC group,the Mankin score of each vibration group was significantly lower(P<0.05),the mRNA and protein expressions of JNK and NF-κB p65 in each vibration training group were significantly lower (P<0.01),the expressions of Sox9 mRNA and protein in vibration training group were increased significantly (P<0.01). Compared with the higher frequency group,the Mankin score,the mRNA and protein expressions of JNK and NF-κB p65 of lower frequency group were significantly lower (P<0.05 or P<0.01). But the expressions of Sox9 mRNA and protein were significantly higher (P< 0.05 or P<0.01). Conclusion: Vibration exercise of different frequencies may present varying degrees of cartilage repair impact in rats with early knee osteoarthritis,and the cartilage repair by low-frequency vibration training is better than that by high-frequency vibration. This can be one of the mechanisms on controlling collagen synthesis by down-regulating JNK/NF-κB expression and increasing SOX9 activity of OA articular cartilage.

ABSTRACT

OBJECTIVE@#To systematically review the therapeutic effect of acupuncture and moxibustion on postoperative gastrointestinal dysfunction (GID) of gastric cancer with meta-analysis.@*METHODS@#The articles of randomized controlled trials (RCTs) of acupuncture and moxibustion treatment for postoperative GID of gastric cancer were retrieved from the following databases from the time of database establishment to December 31, 2020, including PubMed, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI), Wanfang database, VIP database and China Biomedical Literature Database (SinoMed). RevMan5.3 software was used for meta-analysis. Using Stata16.0 software, sensitivity analysis and publication bias test were performed.@*RESULTS@#A total of 16 RCTs were included finally, including 1 360 patients, of which, there were 681 cases in the intervention group and 679 cases in the control group. Meta-analysis results showed that acupuncture and moxibustion shortened the time of first flatus (P<0.000 01, MD =-14.52, 95%CI = [-17.31, -11.74]), the time of first bowel sound (P<0.000 01, MD =-10.50, 95%CI =[-13.99, -7.01]) and the time of first defecation (P<0.000 1, MD =-13.79, 95%CI =[-20.09, -7.50]). Meanwhile, acupuncture and moxibustion shortened the time of the first food intake (P<0.000 1, MD =-3.23, 95%CI = [-3.45, -3.00]) and the hospital stay (P<0.000 01, MD =-1.94, 95%CI =[-2.20, -1.69]) after gastric cancer operation, and reduced the incidences of postoperative adverse reactions, i.e. nausea and vomiting (P =0.000 3, RR =0.43, 95%CI =[0.28, 0.68]) and abdominal distention (P =0.000 5, RR =0.41, 95%CI =[0.25, 0.68]).@*CONCLUSION@#Acupuncture and moxibustion can promote the recovery of postoperative gastrointestinal function in the patients with gastric cancer. But, for the comparison among different measures of acupuncture and moxibustion intervention, it needs more high-quality trials for a further verification.

ABSTRACT

OBJECTIVE@#To compare the effect among ultrasound-guided electroacupuncture (EA) at suprahyoid muscle group, conventional acupuncture and conventional EA at suprahyoid muscle group on pharyngeal dysphagia after stroke, and to explore its biomechanical mechanism.@*METHODS@#A total of 120 patients with pharyngeal dysphagia after stroke were randomly divided into an observation group, a control-1 group and a control-2 group, 40 cases in each group. The patients in the observation group were treated with ultrasound-guided EA at suprahyoid muscle group; the patients in the control-1 group were treated with EA at Lianquan (CV 23), Wangu (GB 12) and Fengchi (GB 20), etc.; the patients in the control-2 group were treated with EA at suprahyoid muscle group according to anatomical location. The EA in the three groups were discontinuous wave, with frequency of 5 Hz and current intensity of 1 mA. The EA was given for 30 minutes, once a day, 6 times were taken as a course of treatment, and 4 courses of treatment were provided. The video floroscopic swallowing study (VFSS) was performed before and after treatment. The Rosenbek penetration-aspiration scale (PAS) score, the forward and upward movement distance of hyoid bone and thyroid cartilage, Ichiro Fujima ingestion-swallowing function score were recorded in the three groups, and the incidences of subcutaneous hematoma were recorded after treatment.@*RESULTS@#Compared before treatment, the PAS scores were reduced and the Ichiro Fujima ingestion-swallowing function scores were increased after treatment in the three groups (P<0.05); the PAS scores in the observation group were lower than those in the control-1 group and the control-2 group, and the Ichiro Fujima ingestion-swallowing function scores in the observation group were higher than those in the control-1 group and the control-2 group (P<0.05). After treatment, the forward and upward movement distance of hyoid bone and thyroid cartilage in the observation group and the control-2 group was increased (P<0.05), and the forward and upward movement distance of hyoid bone was increased in the control-1 group (P<0.05); the forward and upward movement distance of hyoid bone and thyroid cartilage in the observation group was longer than that in the control-1 group and the control-2 group (P<0.05). The incidence of subcutaneous hematoma in the observation group was 0% (0/40), which was lower than 20.0% (8/40) in the control-1 group and 47.5% (19/40) in the control-2 group (P<0.05).@*CONCLUSION@#Ultrasound-guided EA at suprahyoid muscle group could improve the swallowing function in patients with pharyngeal dysphagia after stroke by increasing the motion of hyoid laryngeal complex. Its effect and safety are better than conventional acupuncture and conventional EA at suprahyoid muscle group.

ABSTRACT

Objective: To investigate ferroptosis in laryngeal squamous cell carcinoma (LSCC) and its regulation by M2 macrophage-derived exosomes. Methods: LSCC and adjacent noncancerous tissue samples were collected from 32 patients treated in the Department of Otorhinolaryngology, Head and Neck Surgery of the Second Affiliated Hospital of Harbin between September 2018 and April 2021, including 26 males and 6 females, aged 43-79 years. The expressions of ferroptosis marker glutathione peroxidase 4(GPX4) in LSCC and adjacent noncancerous tissues were detected by immunohistochemistry and reverse transcriptase-polymerase chain reaction(RT-PCR). The correlations between GPX4 expression and clinicopathological factors in LSCC were analyzed. Biological changes of TU212 cells after treated with ferroptosis-induced agent erastin were detected by transmission electron microscope, cell counting kit-8(CCK-8), clone test, reactive oxygen species(ROS), malondialdehyde(MDA), glutathione(GSH), JC-1, RT-PCR and western blot. Exosomes were isolated from the supernatant of M0/M2 macrophages (M0-exos/M2-exos) and co-incubated with erastin-treated TU212 cells to detect the change of ferroptosis in cells of each group. The data were analyzed by SPSS software of version19.0. Results: GPX4 expression in LSCC tissues was significantly higher than that in adjacent noncancerous tissues (2.04±0.65 vs. 0.99±0.09, F=30.36, P<0.001), and was closely related to T stage and clinical stage (Ⅰ-Ⅱvs.Ⅲ-Ⅳ: 1.75±0.39 vs. 2.18±0.71, F=2.25, P<0.05; T1-2 vs. T3-4: 1.71±0.42 vs. 2.20±0.69, F=2.06, P<0.05). In TU212 cells treated with erastin, mitochondrial crest became smaller, membrane density increased, proliferation rate decreased, intracellular ROS level increased, mitochondrial membrane potential depolarized, GSH content decreased, intracellular MDA level increased and expressions of GPX4 mRNA and protein decreased. Change of M0 into M2 macrophages was induced by IL-4 stimulation. When erastin-treated TU212 cells were incubated with M2-exos, cell proliferation was partially restored and GPX4 expression was enhanced, and also with the recoveries of levels of ROS, MDA and GSH (all P<0.05). Conclusions: Ferroptosis is one of the cell death ways of LSCC. M2-exos may inhibit ferroptosis of LSCC cells.

ABSTRACT

Mitochondria is involved in many important physiological activities such as energy supply, signal transduction, cell differentiation, etc., and plays an significant role in the occurrence and development of diseases. Using mitochondria as a target is a new strategy for cancer treatment. The use of nanotechnology to construct a mitochondrial targeted nano-drug delivery system can improve the solubility of traditional drugs, prolong the half-life of drugs in the body, increase the bioavailability and concentration of drugs at the tumor site, and reduce the toxic and side effects of drugs. It is expected to solve the resistance in the process of tumor treatment. This review focuses on the field of cancer treatment. Firstly, it introduces the mechanism of mitochondrial targeted nano-drug delivery system for cancer treatment. Secondly, it outlines the design ideas, classification and application research of mitochondrial targeted nano-drug delivery systems in the past five years. Finally, it expands the analysis of other studies that target mitochondria, such as bionic vectors, and presents its advantages and disadvantages, which provide a basis for in-depth research on drug delivery systems in the future.
