ABSTRACT

Zanthoxylum belongs to the Rutaceae family, and there are 81 Zanthoxylum species and 36 varieties in China. Most of the Zanthoxylum plants are used as culinary spice. In recent years, scholars in China and abroad have carried out in-depth research on Zanthoxylum plants, and found that the peculiar numbing sensation of Zanthoxylum plants originates from amides. It is also determined that amides are an important material basis for exerting pharmacological effects, especially in anti-inflammatory analgesia, anesthesia and other aspects. In this paper, 123 amides in 26 Zanthoxylum plants and their pharmacological activity that have been reported were summarized, which provided scientific reference for the clinical application of Zanthoxylum plants and the research and development of new drugs, and also facilitated the sustainable development and utilization of Zanthoxylum plant resources.

ABSTRACT

OBJECTIVE@#The study aimed to estimate the benchmark dose (BMD) of coke oven emissions (COEs) exposure based on mitochondrial damage with the mitochondrial DNA copy number (mtDNAcn) as a biomarker.@*METHODS@#A total of 782 subjects were recruited, including 238 controls and 544 exposed workers. The mtDNAcn of peripheral leukocytes was detected through the real-time fluorescence-based quantitative polymerase chain reaction. Three BMD approaches were used to calculate the BMD of COEs exposure based on the mitochondrial damage and its 95% confidence lower limit (BMDL).@*RESULTS@#The mtDNAcn of the exposure group was lower than that of the control group (0.60 ± 0.29 vs. 1.03 ± 0.31; P < 0.001). A dose-response relationship was shown between the mtDNAcn damage and COEs. Using the Benchmark Dose Software, the occupational exposure limits (OELs) for COEs exposure in males was 0.00190 mg/m 3. The OELs for COEs exposure using the BBMD were 0.00170 mg/m 3 for the total population, 0.00158 mg/m 3 for males, and 0.00174 mg/m 3 for females. In possible risk obtained from animal studies (PROAST), the OELs of the total population, males, and females were 0.00184, 0.00178, and 0.00192 mg/m 3, respectively.@*CONCLUSION@#Based on our conservative estimate, the BMDL of mitochondrial damage caused by COEs is 0.002 mg/m 3. This value will provide a benchmark for determining possible OELs.

ABSTRACT

OBJECTIVE@#To develop a few-shot learning (FSL) approach for classifying optical coherence tomography (OCT) images in patients with inherited retinal disorders (IRDs).@*METHODS@#In this study, an FSL model based on a student-teacher learning framework was designed to classify images. 2,317 images from 189 participants were included. Of these, 1,126 images revealed IRDs, 533 were normal samples, and 658 were control samples.@*RESULTS@#The FSL model achieved a total accuracy of 0.974-0.983, total sensitivity of 0.934-0.957, total specificity of 0.984-0.990, and total F1 score of 0.935-0.957, which were superior to the total accuracy of the baseline model of 0.943-0.954, total sensitivity of 0.866-0.886, total specificity of 0.962-0.971, and total F1 score of 0.859-0.885. The performance of most subclassifications also exhibited advantages. Moreover, the FSL model had a higher area under curves (AUC) of the receiver operating characteristic (ROC) curves in most subclassifications.@*CONCLUSION@#This study demonstrates the effective use of the FSL model for the classification of OCT images from patients with IRDs, normal, and control participants with a smaller volume of data. The general principle and similar network architectures can also be applied to other retinal diseases with a low prevalence.

ABSTRACT

OBJECTVE To study the improvement effects of obacunone on renal interstitial fibrosis (RIF) in unilateral ureteral obstruction (UUO) model mice, and to investigate its mechanism based on ferroptosis mediated by nuclear factor erythroid 2- related factor 2(Nrf2)/glutathione peroxidase 4 (GPx4) signaling pathway. METHODS Thirty mice were randomly divided into sham operation group, model group, irbesartan group (positive control, 20 mg/kg), obacunone low-dose and high-dose groups (10, 40 mg/kg), with 6 mice in each group. Except for sham operation group, UUO model was established by ligation of unilateral ureter in other groups. After operation, administration groups were given intraperitoneal injection of relevant medicine, and sham operation group and model group were given intraperitoneal injection of constant volume of normal saline, once a day, for 7 consecutive days. The levels of creatinine (Cr) and blood urea nitrogen (BUN), the content of malondialdehyde (MDA) and the activities of total superoxide dismutase (T-SOD) in serum and the concentration of Fe2+ in renal tissue were all detected. HE staining and Masson staining were performed to observe the morphology and the fibrosis of renal tissues. Immunohisto- chemical staining was used to determine expressions of the fibronectin (Fn), α-smooth muscle actin (α-SMA), GPx4 964083717@qq.com and Nrf2 in renal tissue. Western blot and real-time quantitative polymerase chain reaction (RT-qPCR) were used E-mail:834300205@qq.com to detect the protein and mRNA levels of Fn, α-SMA, Nrf2, GPx4 and SLC7A11 in the renal tissues. RESULTS Compared with sham operation group, serum levels of Cr and BUN, the concentration of Fe2+ in renal tissue, the protein and mRNA levels of Fn and α-SMA in model group were increased significantly (P<0.05), while the activity of T-SOD in serum, protein and mRNA expressions of Nrf2, GPx4, SLC7A11 in kidney tissue were significantly decreased (P<0.05); in the kidney tissue, the renal tubules were dilated, the collagen deposition was obvious, the fibrous bands were thicker and darker, and the renal interstitial inflammatory cells infiltrated significantly. After intervened with obacunone, the levels of above indexes (except for mRNA expression of SLC7A11 in obacunone low-dose group) in serum and renal tissue were reversed significantly (P<0.05), and pathological damage and collagen deposition of kidney tissue were alleviated. CONCLUSIONS Obacunone can improve renal interstitial fibrosis of UUO model mice, the mechanism of which may be associated with activating the Nrf2/GPx4 pathway and then inhibiting ferroptosis to relieve RIF in UUO model mice.

ABSTRACT

Bile acids (BAs) are a group of endogenous steroid molecules that regulate lipid, glucose and energy metabolism. They play an important role in maintaining body homeostasis and physiological functions as key signaling molecules for host and gut microbial metabolism. The accurate characterization and quantification of BAs in vivo is of great importance in basic and clinical research. Over the past decades, enzymatic assay, enzyme-linked immunoassay, nuclear magnetic resonance (NMR), chromatography, and other related techniques have been developed and applied to the detection of BAs. The diverse structures of BAs, the existence of isomers and the complex matrix of biological samples pose great challenges for the detection of endogenous BAs. Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) is a robust analytical technique that combines the rapid separation capacities of UPLC with the powerful structural identification capabilities of MS/MS, facilitating the more rapid separation, characterization and accurate quantitative of target analytes in biological samples. UPLC-MS/MS has been widely used in the quantitative analysis of BAs in recent years for its high selectivity, high sensitivity, and high accuracy. This paper summarized the biosynthetic pathways of BAs, sample pretreatment methods, common analytical detection techniques, and highlights the current status of the application of UPLC-MS/MS technology in the analysis of endogenous BAs over the past five years, to provide a reference for the accurate detection of endogenous BAs and further research development and application.

ABSTRACT

OBJECTIVE To develop an individualized medication list for elderly patients by evidence-based pharmacy method, and to support clinical decisions on rational use of METHODS Firstly, drugs with risk genetic information were screened out by systematically reviewing evidence-based pharmacy information. Secondly, researchers investigated the included drugs in lists from different data E- sources. Drugs included in three or more data sources and drugs proposed by the expert committee were then included in the medication list. Thirdly, for the drugs included in two data sources, researchers designed questionnaires to investigate the necessity of drug-related gene testing. According to the scoring results of the expert questionnaire, drugs with higher scores were included in the list. Data sources included real-world data (list of high frequency medication in hospitals, high frequency medication for elderly outpatients and inpatients in National Health Care Claims Data, drugs related to frequent medication errors and so on) and evidence-based pharmacy evidence (the websites of Clinical Pharmacogenomics Implementation Consortium, Dutch Pharmacogenetics Working Group, Food and Drug Administration and so on). RESULTS The study obtain 68 drugs with risk genetic information which were included in three data sources. Combined with 23 drugs proposed by the expert committee, a list containing 74 drugs was preliminarily formed after de-duplication. A total of 37 drugs included in two databases with risk genetic information were scored through the questionnaire survey to form a supplementary list of 26 drugs. This is the final composition of the list of 100 drugs developed in this study. Among them, there are 43 drugs for the central nervous system, 15 drugs for the cardiovascular system, 12 anti-tumor drugs and so on. Twelve drugs were included in six or more data sources, which mainly consisted of drugs for digestive system, all proton pump inhibitors. CONCLUSION In this study, a list of 100 commonly used drugs which require individualized medication for the elderly was developed by evidence-based pharmacy method. The drug list will be updated in time as available evidence changes, and can provide guidance for rational use of medicines for elderly patients.

ABSTRACT

Objective To investigate the occupational lead exposure and blood lead levels of workers in a lead-acid battery factory in Wuhan in 2020 and analyze the influencing factors of blood lead, and to provide reference for the blood lead intervention of the workers in the lead-acid battery factory. Methods The blood lead test results of 320 occupational lead-exposed workers in the factory were investigated and the influencing factors were analyzed. Results Among the 320 blood lead samples collected, 4 people had blood lead≥400 μg/L, accounting for 1.25%, and 89 people had blood lead≥200 μg/L, accounting for 27.81%. Among them, there were 235 males with a median blood lead of 155.10 μg/L, and 85 females with a median blood lead of 82.40 μg/L. The Wilcoxon rank sum test results of two independent samples showed that the overall blood lead level of male employees was higher than that of female employees, and the difference was statistically significant (P 50 years old. Using the Bonferroni method to adjust the significance level for pairwise comparison, it was found that there were significant differences in the blood lead concentrations between the group under 40 years old, the group of 40 - 50 years old, and the group of over 50 years old ( P < 0.016 after adjustment). The employees were classified into different workshops, including 38 samples from the administrative workshop , 40 samples from the charging workshop, and 242 samples from the assembly workshop. Using the Bonferroni method to adjust the significance level for pairwise comparison, it was found that the blood lead concentrations in the administrative workshop, the charging workshop, and the assembly workshop were statistically different ( P <0.016 after adjustment). Conclusion The age, gender, and type of work of the employees in the battery factory all have a certain impact on the blood lead level. It is necessary to continuously improve the management of the labor hygiene operation system and strengthen the self-protection level of the workers, and regularly carry out occupational hygiene inspection and health monitoring.

ABSTRACT

Kidney is a highly vascularized organ and peritubular capillary network constitutes the critical component of its microvascular system. Peritubular capillaries, as the main vessels for blood supply in renal tubules and renal interstitium, involve in important physiological processes in renal tubules such as energy metabolism, substance secretion and reabsorption. In recent years, it has been demonstrated that ischemia-reperfusion injury, rejection and renal fibrosis during kidney transplantation would result in compromised structural integrity and decreased number in peritubular capillaries, thus leading to interstitial fibrosis in renal allograft, which would seriously affect the long-term stability of renal function in the renal allograft. Therefore, we reviewed the structure and function of peritubular capillary, peritubular capillary and ischemia-reperfusion injury, rejection and renal allograft fibrosis, focusing on the mechanism for peritubular capillary injury in kidney transplantation and the specific changes manifested, with the aim of providing a reference for preventing and treating perioperative complications in kidney transplantation and improving the long-term prognosis of grafts.

ABSTRACT

Objective:To study the short-term clinical outcomes of different courses of antenatal corticosteroids (ACS) for preterm twins.Methods:From January 2017 to December 2021, preterm twins with gestational age (GA) 24-34 weeks admitted to the neonatal ward of our hospital and received ACS were retrospectively studied. The infants were assigned into single-course group, partial-course group and multiple-course group according to ACS courses. The short-term clinical outcomes were compared among the groups. SPSS software version 25.0 was used for statistical analysis.Results:A total of 286 infants were enrolled in this study, including 128 in single-course group, 89 in partial-course group and 69 in multiple-course group. Compared with single-course group, the risks of neonatal respiratory distress syndrome (RDS) in both partial-course group ( OR=2.332, 95% CI 1.028-5.293, P=0.043) and multiple-course group ( OR=3.872, 95% CI 1.104-13.584, P=0.034) were higher. The birth length in multiple-course group ( β=-0.016, 95% CI -0.029 - -0.002, P=0.024) was lower than single-course group. Conclusions:The risks of neonatal RDS in preterm twins are higher in partial-course and multiple-course of ACS. A full course of ACS should be used to prevent neonatal RDS until further evidence of effectiveness is available.

ABSTRACT

Objective:To investigate the safety and short-term efficacy of laparoscopic pro-ximal gastrectomy (LPG) for proximal gastric cancer and adenocarcinoma of esophagogastric junction.Methods:The retrospective cohort study was conducted. The clinicopathological data of 385 patients with proximal gastric cancer and adenocarcinoma of esophagogastric junction who underwent LPG in the 15 medical centers, including the First Affiliated Hospital of Xiamen University et al, from January 2014 to March 2022 were collected. There were 304 males and 81 females, aged (63±9)years. Of the 385 patients, 335 cases undergoing LPG were divided into the laparoscopic group and 50 cases undergoing open proximal gastrectomy were divided into the open group. Observation indicators: (1) intraoperative and postoperative situations; (2) follow-up; (3) stratified analysis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Intraoperative and postoperative situations. The operation time, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, cases with postoperative pathological staging as stage 0?Ⅰ and stage Ⅱ?Ⅲ, duration of postoperative hospital stay, cases with postoperative early complications were (212±96)minutes, 270, 65, 177, 107, 10(range, 8?14)days, 40 in patients of the laparoscopic group, with 51 cases missing the data of postoperative pathological staging. The above indicators were (174±90)minutes, 39, 11, 22, 28, 10(range, 8?18)days, 10 in patients of the open group.

It was convenient to select 312 lung neoplasms patients treated in the Department of Oncology, First Affiliated Hospital and Second Affiliated Hospital of Air Force Military Medical University the Chinese People′s Liberation Army, from April 2021 to April 2022 as the research subjects. Questionnaires were conducted with Fatalism Scale, Attention to Negative Information Scale, and Templer′s Death Anxiety Scale. Structural equation model were constructed based on self-regulatory executive function models.Results:The total score of fatalism, attentional bias of negative information, and death anxiety of 312 lung neoplasms patients were (61.68 ± 11.92) points, (39.57 ± 5.19) points, and (61.23 ± 9.30) points, respectively. Attentional bias of negative information was significantly positively correlated with fatalism ( r = 0.594, P<0.01). Death anxiety was significantly positively correlated with fatalism and attentional bias of negative information ( r = 0.494, 0.558, both P<0.01). Attentional bias of negative information played a partial mediating role between fatalism and death anxiety, and the mediating effect accounted for 37.7% of the total effect. The value of each fitness index of the mediation effect model was within the acceptable range. Conclusions:Attentional bias of negative information is an intermediary variable between fatalism and death anxiety of lung neoplasms patients. Nursing staff should pay attention to the level of attentional bias of negative information of lung neoplasms patients and carry out targeted nursing interventions from the emotional processing process to reduce the level of death anxiety in patients with lung neoplasms.

ABSTRACT

Objective:To explore the status of social alienation among survivors of nasopharyngeal carcinoma and analyze its influencing factors.Methods:This study was a cross-sectional study. From October 2021 to January 2022, 200 survivors of nasopharyngeal carcinoma reviewed in the radiotherapy department of the First Affiliated Hospital of Guangxi Medical University were investigated by General Data Questionnaire, General Alienation Scale (GAS), Cancer Fatigue Scale (CFS) and Self-Perceived Burden Scale (SPBS).Results:The total score of GAS in survivors of nasopharyngeal carcinoma was (37.47 ± 2.88) points. The total scores of GAS were positively correlated with the total score and each dimension score of CFS and SPBS ( r values were 0.312-0.524, all P<0.01). Multivariable linear regression showed that the duration of diagnosis, whether or not having hearing loss, the number of symptoms, cancer fatigue and self-perceived burden were the main influencing factors of social alienation in survivors of nasopharyngeal carcinoma( t values were -3.99-4.86, all P<0.05), which could explain 49% of the total variation. Conclusions:Clinical medical staff should attach importance to social alienation of surviors of nasopharyngeal carcinoma. More attention should be paid to patients with less than one year of diagnosis, a large number of symptoms and hearing loss, and targeted intervention should be conducted to reduce the degree of social alienation of patients and promote their integration into society.

ABSTRACT

Objective:To investigate the correlation between triglyceride-glucose (TyG) index and high on-treatment platelet reactivity (HTPR) during clopidogrel treatment in patients with ischemic stroke.Methods:Patients with ischemic stroke who received maintenance dose of clopidogrel (75 mg/d) in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2017 to March 2021 were retrospectively included. The highest quartile (Q4) of the TyG index was defined as insulin resistance. Platelet reactivity was assessed by thromboelastogram and clopidogrel HTPR was defined as the clot strength induced by adenosine diphosphate (MA ADP) >47 mm. Multivariate regression model was used to analyze the independent correlation between TyG index and platelet reactivity. Results:A total of 83 patients were included. The TyG index showed a linear correlation with MA ADP. The patients were divided into 4 groups according to the quartile of TyG index. The incidence of clopidogrel HTPR increased significantly with the increase of the quartile of the TyG index ( Ptrend=0.017). Multivariate analysis showed that there was a significant independent correlation between insulin resistance and clopidogrel HTPR (odds ratio 4.597, 95% confidence interval 1.285-16.446; P=0.019). Conclusions:In patients with ischemic stroke treated with clopidogrel, the incidence of clopidogrel HTPR gradually increases with the increase of the quartile of the TyG index. The insulin resistance assessed by the TyG index is independently associated with clopidogrel HTPR.

ABSTRACT

AIM:To explore the effect of genetic factors on the pathogenesis of keratoconus and its genetic model.METHODS: Genetic epidemiological methods were used to investigate the prevalence of keratoconus in 280 first-degree relatives of 100 patients with keratoconus who attended Henan Eye Hospital between July 2020 and April 2023. The heritability was estimated by Falconer regression method. The general genetic model was calculated using Penrose method, and the genetic model was confirmed by Falconer formula, Edwards approximation formula and the projection formula of San-Duo Jiang's threshold model theory.RESULTS: The results showed that there were 16(5.714%)first-degree relatives of keratoconus probands suffering from keratoconus, and the heritability of keratoconus was(86.100±7.400)%. The S/q score calculated by the Penrose method was 35.348, which was near to 1/(q)1/2, suggesting that the genetic model of keratoconus might be polygenic inheritance. The expected prevalence in first-degree relatives of keratoconus patients by Falconer formula, Edwards approximation formula and the projection formula of San-Duo Jiang's threshold model theory were 5.900%, 7.714% and 5.700%, respectively, which showed no significant differences from the actual prevalence(5.714%), suggesting that keratoconus was a polygenetic disease.CONCLUSION:Genetic factors might play an important role in the pathogenesis of keratoconus, and keratoconus is a polygenetic disease.

ABSTRACT

Although it has become a consensus in the field of colorectal surgery to perform radical tumor treatment and functional protection under the minimally invasive concept, there exist many controversies during clinical practice, including the concept of embryonic development of abdominal organs and membrane anatomy, the principle of membrane anatomy related to right hemicolectomy, D3 resection, and identification of the inner boundary. In this paper, we analyzed recently reported literature with high-level evidence and clinical data from the author's hospital to recognize and review the membrane anatomy-based laparoscopic assisted right hemicolectomy for right colon cancer, emphasizing the importance of priority of surgical dissection planes, vascular orientation, and full understanding of the fascial space, and proposing that the surgical planes should be dissected in the parietal-prerenal fascial space, and the incision should be 1 cm from the descending and horizontal part of the duodenum. The surgery should be performed according to a standard procedure with strict quality control. To identify the resection range of D3 dissection, it is necessary to establish a clinical, imaging, and pathological evaluation model for multiple factors or to apply indocyanine green and nano-carbon lymphatic tracer intraoperatively to guide precise lymph node dissection. We expect more high-level evidence of evidence-based medicine to prove the inner boundary of laparoscopic assisted radical right colectomy and a more rigorous consensus to be established.

ABSTRACT

Objective: To investigate the clinical characteristics of patients with acute phosphine poisoning, and to follow up and evaluate the prognosis of patients. Methods: In May 2022, 12 patients with phosphine poisoning by respiratory inhalation in Beijing Chao-Yang Hospital of Capital Medical University were analyzed. The patients were treated with symptomatic support therapy. Three months later, patients were re-evaluated the symptoms of poisoning, pulmonary function and magnetic resonance imaging (MRI) of the brain to understand the prognosis of the phosphine poisoning. Results: The main symptoms of 12 patients were respiratory and central nervous system symptoms with hypoxia. The symptoms of poisoning improved after treatment. Follow-up found that the patients had different degrees of residual symptoms. Pulmonary function showed increased airway resistance. Airway challenge test was positive in some patients. MRI of the head of some patients showed small ischemic focus in bilateral frontal lobes. Conclusion: Acute phosphine poisoning may cause persistent damage to the respiratory system and central system, and residual symptoms after 3 months.
