ABSTRACT

This paper aimed to study the effect of Erjing Pills on the improvement of neuroinflammation of rats with Alzheimer's di-sease(AD) induced by the combination of D-galactose and Aβ_(25-35) and its mechanism. SD rats were randomly divided into a sham group, a model control group, a positive drug group(donepezil, 1 mg·kg~(-1)), an Erjing Pills high-dose group(9.0 g·kg~(-1)), and an Erjing Pills low-dose group(4.5 g·kg~(-1)), with 14 rats each group. To establish the rat model of AD, Erjing Pills were intragastrically administrated to rats for 5 weeks after 2 weeks of D-galactose injection. D-galactose was intraperitoneally injected into rats for 3 weeks, and then Aβ_(25-35) was injected into the bilateral hippocampus. The new object recognition test was used to evaluate the learning and memory ability of rats after 4 weeks of intragastric administration. Tissues were acquired 24 h after the last administration. The immunofluorescence method was used to detect the activation of microglia in the brain tissue of rats. The positive expressions of Aβ_(1-42) and phosphory protein Tau~(404)(p-Tau~(404)) in the CA1 area of the hippocampus were detected by immunohistochemistry. The levels of inflammatory factors interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), and interleukin-6(IL-6) in the brain tissue were determined by enzyme-linked immunosorbent assay(ELISA). Toll-like receptor 4(TLR4)/nuclear factor kappa B(NF-κB)/nucleotide-binding oligomerization domain-like receptors 3(NLRP3) pathway-associated proteins in the brain tissue were determined by Western blot. The results showed that as compared with the sham group, the new object recognition index of rats in the model control group decreased significantly, the deposition of Aβ_(1-42) and p-Tau~(404) positive protein in the hippocampus increased significantly, and the levels of microglia activation increased significantly in the dentate gyrus. The levels of IL-1β, TNF-α, and IL-6 in the hippocampus of the model control group increased significantly, and the expression levels of TLR4, p-NF-κB p65/NF-κB p65, p-IκBα/IκBα, and NLRP3 proteins in the hippocampus increased significantly. Compared with the model control group, the Erjing Pill groups enhanced the new object recognition index of rats, decreased the deposition of Aβ_(1-42) and the expression of p-Tau~(404) positive protein in the hippocampus, inhibited the activation of microglia in the dentate gyrus, reduced the levels of inflammatory factors IL-1β, TNF-α, and IL-6 in the hippocampus, and down-regulated the expression levels of TLR4, p-NF-κB P65/NF-κB P65, p-IκBα/IκBα, and NLRP3 proteins in the hippocampus. In conclusion, Erjing Pills can improve the learning and memory ability of the rat model of AD presumably by improving the activation of microglia, reducing the expression levels of neuroinflammatory factors IL-1β, TNF-α, and IL-6, inhibiting the TLR4/NF-κB/NLRP3 neuroinflammation pathway, and decreasing hippocampal deposition of Aβ and expression of p-Tau, thereby restoring the hippocampal morphological structure.

ABSTRACT

Objective: To analyze the residents' sense of acquisition (recognition, perceptibility and satisfaction) and influencing factors in China's Sanitary City Initiative. Methods: A cross-sectional survey was conducted from December 2020 to February 2021. The data about the residents' sense of acquisition were collected by using questionnaire from 2 465 residents who were aged ≥18 years and had lived in local communities for at least one year in 31, 14 and 16 cities with national sanitary city title in eastern, central and western China the influencing factors of residents' sense of acquisition in China's Sanitary City Initiative were analyzed by using multivariate multilevel model. Results: The total score of residents' sense of acquisition in China's Sanitary City Initiative was 231.15±32.45. After converting the scores according to the 100-score standardized method, the results showed that the recognition score, perception score and the satisfaction score were 85.02, 59.08 and 61.42, respectively. The results of influencing factors analysis showed that education level, gender, marital status, age, prevalence of physical exercise and self-assessment of health status were correlated with the scores of residents' recognition (β:1.24-2.54,all P<0.05); the concentration of inhalable fine particles , the green coverage of built-up area, the level of GDP per capita and the type of residential community, prevalence of physical exercise and self-assessment of health status were correlated with the score of residents' perception (β:1.76-8.86,all P<0.05); the concentration of inhalable fine particles , the green coverage of built-up area, the level of GDP per capita and the type of residential community, education level, prevalence of physical exercise and self-assessment of health status were correlated with the score of residents' satisfaction (β:1.34-6.26,all P<0.05). Conclusions: The total score of residents' sense of acquisition in China's Sanitary City Initiative was relatively high, indicating that the policy has been widely recognized. The detailed management of policy implementation should be strengthened in the future, and more attention needs to be paid to actual needs of the residents to further improve the residents' sense of acquisition in China's Sanitary City Initiative.

ABSTRACT

This study investigated the effect of guarana on plasma lipid metabolites in obese rats and analyzed its mechanism in the treatment of dyslipidemia in obesity. High-fat diet was used to establish obese rat models, and the therapeutic effect of guarana on obese rats was evaluated by measuring body weight, white fat, liver weight, and lipid content, as well as observing liver histomorphology. Lipid metabolites in plasma of rats in each group were detected by UHPLC-Q-TOF-MS lipidomics. The protein expressions of fatty acid synthase, acetyl-CoA carboxylase 1, triglyceride synthesis enzyme, carnitine palmitoyltransferase Ⅰ, and acetyl-coenzyme A acyltransferase 2 in rat liver were detected using Western blot. The results revealed that guarana significantly reduced body weight, white fat, and liver weight of obese rats due to high-fat diet, and alleviated dyslipidemia and liver steatosis. Lipidomics showed that some triglycerides and phospholipids were significantly elevated in the high-fat model group, and part of them was reduced after guarana treatment. Western blot found that guarana inhibited the expression of hepatic fatty acid and triglyceride synthesis-related proteins and increased the expression of fatty acid β-oxidation-related proteins. Abnormalities in triglyceride and phospholipid metabolism are the main characteristics of plasma lipid metabolism in obese rats induced by high-fat diet. Guarana may regulate partial triglyceride and phospholipid metabolism by inhibiting hepatic fatty acid and triglyceride synthesis and increasing fatty acid β-oxidation, thereby improving rat obesity and dyslipidemia.

ABSTRACT

Objective: To investigate the efficacy and safety of adrenocorticotropic hormone (ACTH) in children with frequently relapsing or steroid-dependent nephrotic syndrome. Methods: The clinical data of 38 children with frequently relapsing or steroid-dependent nephrotic syndrome who were admitted to the Department of Nephrology, the Children Hospital, Zhejiang University School of Medicine from January 2015 to December 2020 were retrospectively analyzed. The general information, clinical manifestations, laboratory data of the children and follow-up (till 12 months after treatment) were collected. The patients were divided into ACTH group and Glucocorticoid (GC) group according to treatment plan. Cumulative remission, average recurrence rate, GC dosage, height and weight change and peripheral blood CD19+B lymphocyte count were compared between the two groups to evaluate the efficacy and adverse reactions of ACTH. Fisher's exact test, t test or rank sum test was used for comparison between groups. Results: Among the 38 patients, 28 were male and 10 were female, aged 84 (24, 180) months; 19 were in ACTH group and 19 were in GC group. The cumulative remission rate of 12 months in ACTH group was higher than that in GC group (9/19 vs. 2/19,χ²=6.81,P=0.009), the average recurrence rate was lower than that in GC group ((0.7±0.8) vs. (1.7±1.1) times, t=-3.27, P=0.011), and the average dosage of GC was lower than that in GC group ((0.27±0.16) vs. (0.51±0.27) mg/(kg·d), t=-3.21, P=0.014). The increase in height was higher than that in the GC group (4 (3,5) vs. 3 (2, 3) cm/year, Z=2.58, P=0.010), and the peripheral blood CD19+B lymphocyte count was lower than that in the GC group ((223±149)×106 vs. (410±213)×106/L,t=-3.35, P=0.009). In safety, 19 cases had transient decreased urine volume, 7 cases had hyperglycemia, and 3 cases had hypertension during the infusion of ACTH, which could be relieved after drug withdrawal. Conclusion: ACTH has a better effect on children with frequently relapsing or steroid-dependent nephrotic syndrome, which can improve cumulative sustained remission rate, lower relapses rate and decrease the dosage of GC, with good safety.

ABSTRACT

Objective To explore the potential targets of triclosan in the treatment of nonalcoholic fatty liver disease(NAFLD) and to provide new clues for the future research on the application of triclosan. Methods The targets of triclosan and NAFLD were obtained via network pharmacology.The protein-protein interaction network was constructed with the common targets shared by triclosan and NAFLD.The affinity of triclosan to targets was verified through molecular docking.Gene ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment were carried out to analyze the key targets and the potential mechanism of action.NAFLD model was established by feeding male C57BL/6J mice with high-fat diet for 12 weeks.The mice were randomly assigned into a model group and a triclosan group [400 mg/(kg·d),gavage once a day for 8 weeks].The hematoxylin-eosin(HE) staining was used for observation of the pathological changes and oil red O staining for observation of fat deposition in mouse liver.Western blotting was employed to detect the protein level of peroxisome proliferator-activated receptor alpha(PPARα) in the liver tissue. Results Triclosan and NAFLD had 34 common targets,19 of which may be the potential targets for the treatment,including albumin(ALB),PPARα,mitogen-activated protein kinase 8(MAPK8),and fatty acid synthase.Molecular docking predicted that ALB,PPARα,and MAPK8 had good binding ability to triclosan.KEGG pathway enrichment showcased that the targets were mainly enriched in peroxisome proliferator-activated receptor signaling pathway,in which ALB and MAPK8 were not involved.Triclosan alleviated the balloon-like change and lipid droplet vacuole,decreased the lipid droplet area,and up-regulated the expression level of PPARα in mouse liver tissue. Conclusion PPARα is a key target of triclosan in the treatment of NAFLD,which may be involved in fatty acid oxidation through the peroxisome proliferator activated receptor signaling pathway.

ABSTRACT

OBJECTIVE@#To investigate the correlation of intraplaque neovascularization (IPN) detected by carotid contrast-enhanced ultrasound (CEUS) with revascularization in patients following percutaneous coronary intervention (PCI).@*METHODS@#This study was conducted among 105 patients who were followed up for more than 12 months after PCI. All the patients received CEUS examination for assessment of carotid plaque formation and IPN, which were compared between patients with revascularization (REV group, n=27) and those without revascularization (N-REV group, n=78). ROC curve was used to analyze the diagnostic efficacy of CEUS for predicting revascularization. Univariate and multivariate logistic regression analyses were performed to identify the risk factors associated with revascularization.@*RESULTS@#In the REV group, the IPN score was 0 in 1 (3.7%) patient, 1 in 8 (29.6%) patients, 2 in 15 (55.6%) patients and 3 in 3 (11.1%) patients. Significant differences were noted between REV and N-REV groups in plaque length (15.70±6.93 vs 12.10±6.64, P < 0.05), maximum plaque thickness (3.69±1.12 vs 3.14±1.18, P < 0.05) and IPN (1.74±0.71 vs 0.87±0.63, P < 0.001). IPN score was identified as an independent risk factor for revascularization in patients following PCI, and at the cutoff value of 1.5, its sensitivity, specificity, positive predictive value, and negative predictive value for predicting the occurrence of revascularization were 74%, 89%, 69%, and 91%, respectively, with an AUC of 0.848 (95% CI: 0.703-0.905, P < 0.001).@*CONCLUSION@#CEUS allows noninvasive and semi-quantitative assessment of neovascularization in carotid artery plaques, and IPN detected by CEUS is correlated with the risk of revascularization in patients following PCI.

ABSTRACT

Professor WU Zhong-chao's clinical experience of "dredging stagnation and collaterals" acupuncture for migraine is summarized. Professor WU proposes that occiput-nape dysfunction, meridians-tendons dysfunction and stagnation of collaterals due to obstruction of excess-evil could lead to migraine. As such, migraine is treated by comprehensive treatment of adjusting occiput-nape functional zone, relaxing meridians-tendons and blood-letting combined with fire acupuncture.

ABSTRACT

Median arcuate ligament syndrome(MALS)is compression of the celiac trunk by the median arcuate ligament.Median arcuate ligament release is the corner stone for the surgical treatment of MALS.Open surgery,laparoscopic surgery,and robot-assisted surgery have been developed,among which laparoscopic surgery has been proposed as the preferred approach in view of its minimal trauma and short hospital stay.Auxiliary celiac plexus neurolysis could further alleviate the patient's discomfort.Moreover,vascular reconstitution is of vital importance in the case of persistent stenosis in the celiac artery despite of median arcuate ligament decompression.Vascular reconstruction has satisfactory long-term patency rate,while endovascular treatment is less invasive.This article aims to summarize the consensuses and advances and shed light on the surgical treatment of MALS.

ABSTRACT

BACKGROUND@#Fetal weight is an important parameter to ensure maternal and child safety. The purpose of this study was to use three-dimensional (3D) limb volume ultrasound combined with fetal abdominal circumference (AC) measurement to establish a model to predict fetal weight and evaluate its efficiency.@*METHODS@#A total of 211 participants with single pregnancy (28-42 weeks) were selected between September 2017 and December 2018 in the Beijing Obstetrics and Gynecology Hospital of Capital Medical University. The upper arm (AVol)/thigh volume (TVol) of fetuses was measured by the 3D limb volume technique. Fetal AC was measured by two-dimensional ultrasound. Nine cases were excluded due to incomplete information or the interval between examination and delivery >7 days. The enrolled 202 participants were divided into a model group (134 cases, 70%) and a verification group (68 cases, 30%) by mechanical sampling method. The linear relationship between limb volume and fetal weight was evaluated using Pearson Chi-squared test. The prediction model formula was established by multivariate regression with data from the model group. Accuracy of the model formula was evaluated with verification group data and compared with traditional formulas (Hadlock, Lee2009, and INTERGROWTH-21st) by paired t-test and residual analysis. Receiver operating characteristic curves were generated to predict macrosomia.@*RESULTS@#AC, AVol, and TVol were linearly related to fetal weight. Pearson correlation coefficient was 0.866, 0.862, and 0.910, respectively. The prediction model based on AVol/TVol and AC was established as follows: Y = -481.965 + 12.194TVol + 15.358AVol + 67.998AC, R2adj = 0.868. The scatter plot showed that when birth weight fluctuated by 5% (i.e., 95% to 105%), the difference between the predicted fetal weight by the model and the actual weight was small. A paired t-test showed that there was no significant difference between the predicted fetal weight and the actual birth weight (t = -1.015, P = 0.314). Moreover, the residual analysis showed that the model formula's prediction efficiency was better than the traditional formulas with a mean residual of 35,360.170. The combined model of AVol/TVol and AC was superior to the Lee2009 and INTERGROWTH-21st formulas in the diagnosis of macrosomia. Its predictive sensitivity and specificity were 87.5% and 91.7%, respectively.@*CONCLUSION@#Fetal weight prediction model established by semi-automatic 3D limb volume combined with AC is of high accuracy, sensitivity, and specificity. The prediction model formula shows higher predictive efficiency, especially for the diagnosis of macrosomia.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03002246; https://clinicaltrials.gov/ct2/show/NCT03002246?recrs=e&cond=fetal&draw=8&rank=67.

ABSTRACT

OBJECTIVE@#To observe the effect of five-element acupuncture on the cognitive function repair of migraine patients with depression/anxiety disorder.@*METHODS@#The migraine patients with depression/anxiety disorder (19 cases, 5 cases dropped off) were taken as the observation group, and received five-element acupuncture twice a week for 8 weeks. Healthy subjects (19 cases) were selected by demographic data matching as the control group. The cognitive function was evaluated with the event related potential (ERP) technique, and the latency and amplitude of visual evoked potential P300 were adopted as the observation indexes. The headache days (every 4 weeks), headache intensity [visual analogue scale(VAS) score], and headache impact test-6 (HIT-6) score, Hamilton depression scale (HAMD) score and Hamilton anxiety scale (HAMA) score were used as the observation indexes for curative effect.@*RESULTS@#Before the treatment, latency of target stimulus at Fz [ (417.5±34.3) ms] in the observation group was extended compared with the healthy subjects of the control group [(388.6±42.1) ms, @*CONCLUSION@#There are some cognitive impairments in migraine patients with depression/anxiety disorder. Five-element acupuncture not only relieves headache, anxiety and depression effectively, but also improves the activation level of the frontal lobe. It significantly repairs the impaired cognitive function.

ABSTRACT

BACKGROUND@#Prenatal evaluation of fetal lung maturity (FLM) is a challenge, and an effective non-invasive method for prenatal assessment of FLM is needed. The study aimed to establish a normal fetal lung gestational age (GA) grading model based on deep learning (DL) algorithms, validate the effectiveness of the model, and explore the potential value of DL algorithms in assessing FLM.@*METHODS@#A total of 7013 ultrasound images obtained from 1023 normal pregnancies between 20 and 41 + 6 weeks were analyzed in this study. There were no pregnancy-related complications that affected fetal lung development, and all infants were born without neonatal respiratory diseases. The images were divided into three classes based on the gestational week: class I: 20 to 29 + 6 weeks, class II: 30 to 36 + 6 weeks, and class III: 37 to 41 + 6 weeks. There were 3323, 2142, and 1548 images in each class, respectively. First, we performed a pre-processing algorithm to remove irrelevant information from each image. Then, a convolutional neural network was designed to identify different categories of fetal lung ultrasound images. Finally, we used ten-fold cross-validation to validate the performance of our model. This new machine learning algorithm automatically extracted and classified lung ultrasound image information related to GA. This was used to establish a grading model. The performance of the grading model was assessed using accuracy, sensitivity, specificity, and receiver operating characteristic curves.@*RESULTS@#A normal fetal lung GA grading model was established and validated. The sensitivity of each class in the independent test set was 91.7%, 69.8%, and 86.4%, respectively. The specificity of each class in the independent test set was 76.8%, 90.0%, and 83.1%, respectively. The total accuracy was 83.8%. The area under the curve (AUC) of each class was 0.982, 0.907, and 0.960, respectively. The micro-average AUC was 0.957, and the macro-average AUC was 0.949.@*CONCLUSIONS@#The normal fetal lung GA grading model could accurately identify ultrasound images of the fetal lung at different GAs, which can be used to identify cases of abnormal lung development due to gestational diseases and evaluate lung maturity after antenatal corticosteroid therapy. The results indicate that DL algorithms can be used as a non-invasive method to predict FLM.

ABSTRACT

BACKGROUND@#High-frequency irreversible electroporation (H-FIRE) is a novel, next-generation nanoknife technology with the advantage of relieving irreversible electroporation (IRE)-induced muscle contractions. However, the difference between IRE and H-FIRE with distinct ablation parameters was not clearly defined. This study aimed to compare the efficacy of the two treatments in vivo.@*METHODS@#Ten Bama miniature swine were divided into two group: five in the 1-day group and five in the 7-day group. The efficacy of IRE and H-FIRE ablation was compared by volume transfer constant (Krans), rate constant (Kep) and extravascular extracellular volume fraction (Ve) value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), size of the ablation zone, and histologic analysis. Each animal underwent the IRE and H-FIRE. Temperatures of the electrodes were measured during ablation. DCE-MRI images were obtained 1, 4, and 7 days after ablation in the 7-day group. All animals in the two groups were euthanized 1 day or 7 days after ablation, and subsequently, IRE and H-FIRE treated liver tissues were collected for histological examination. Student's t test or Mann-Whitney U test was applied for comparing any two groups. One-way analysis of variance (ANOVA) test and Welch's ANOVA test followed by Holm-Sidak's multiple comparisons test, one-way ANOVA with repeated measures followed by Bonferroni test, or Kruskal-Wallis H test followed by Dunn's multiple comparison test was used for multiple group comparisons and post hoc analyses. Pearson correlation coefficient test was conducted to analyze the relationship between two variables.@*RESULTS@#Higher Ve was seen in IRE zone than in H-FIRE zone (0.14 ± 0.02 vs. 0.08 ± 0.05, t = 2.408, P = 0.043) on day 4, but no significant difference was seen in Ktrans or Kep between IRE and H-FIRE zones at all time points (all P > 0.05). For IRE zone, the greatest Ktrans was seen on day 7, which was significantly higher than that on day 1 (P = 0.033). The ablation zone size of H-FIRE was significantly larger than IRE 1 day (4.74 ± 0.88 cm2vs. 3.20 ± 0.77 cm2, t = 3.241, P = 0.009) and 4 days (2.22 ± 0.83 cm2vs. 1.30 ± 0.50 cm2, t = 2.343, P = 0.041) after treatment. Apoptotic index (0.05 ± 0.02 vs. 0.73 ± 0.06 vs. 0.68 ± 0.07, F = 241.300, P  0.05). Electrode temperature variations were not significantly different between the two zones (18.00 ± 3.77°C vs. 16.20 ± 7.45°C, t = 0.682, P = 0.504). The Ktrans value (r = 0.940, P = 0.017) and the Kep value (r = 0.895, P = 0.040) of the H-FIRE zone were positively correlated with the number of hepatocytes in the ablation zone.@*CONCLUSIONS@#H-FIRE showed a comparable ablation effect to IRE. DCE-MRI has the potential to monitor the changes of H-FIRE ablation zone.

ABSTRACT

Pyroptosis, also known as cell inflammatory necrosis, is different from apoptosis, necrosis, and other forms of cell death in morphological characteristics, occurrence, and regulatory mechanism. It is a new type of programmed cell death dependent on Caspase, which has been discovered and confirmed in recent years. Studies have shown that pyroptosis is closely related to the occurrence of liver diseases, and is critical in alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), liver fibrosis, and liver cancer. Pyroptosis causes inflammatory injury of hepatocytes to promote the occurrence and development of liver diseases by activating Caspase-1, cleaving the effector gasdermin-D (GSDMD), and releasing pro-inflammatory cytokines, such as interleukin-18 (IL-18) and interleukin-1β (IL-1β) mainly through the classical NOD-like receptor protein 3 (NLRP3) inflammasome pathway. Clinically, Chinese medicine in the treatment of liver diseases has unique efficacy and low side effects. In the intervention on liver diseases, Chinese medicine blocks the pyroptosis signaling pathway to relieve the liver inflammation by inhibiting the assembly and activation of NLRP3 inflammasome multiprotein complex, blunting the activity of Caspase-1 or Caspase-4/Caspase-5/Caspase-11, and inhibiting the cleavage of GSDMD to reduce the release of pro-inflammatory cytokines such as IL-18 and IL-1β. Therefore, in-depth investigation of pyroptosis facilitates unveiling its role in the occurrence, development, and prognosis of liver diseases, and the enhancement or inhibition of pyroptosis may provide a new strategy for the prevention and treatment of liver diseases by Chinese medicine. At present, NLRP3 inflammasome, a key protein in the classic pyroptosis signaling pathway, has become an anti-liver disease target of Chinese medicine. This study briefly summarized the relationship between pyroptosis and liver diseases and reviewed the intervention of monomers, compound prescriptions, effective fractions and extracts of Chinese medicine in recent years to provide important guidance for further exploring the pathogenic mechanism of pyroptosis and the treatment of liver diseases with Chinese medicine.
