The plant AT-rich sequence and zinc-binding protein (PLATZ) family is composed of plant-specific zinc finger-like transcription factors, which play important roles in plant growth, development, and stress tolerance. In this study, to gain a better understanding of the PLATZ gene in C. sinensis and elucidate its response under drought and high temperature conditions, the PLATZ gene family of the C. sinensis cultivar 'Tieguanyin' was systematically identified, and a total of 12 CsPLATZ family members were identified. Expasy online and other bioinformatics tools were used to analyze the members of the PLATZ gene family in terms of protein physicochemical properties, phylogenetic relationships, cis-acting elements, gene structures, and intra- and inter-species collinearity. The results of phylogenetic analysis classified the CsPLATZ family members into 2 subfamilies. The conserved domains and gene structures of PLATZ family members within the same subfamily had a high degree of consistency, whereas a certain degree of diversity was observed among the subfamilies. Twelve PLATZ genes were unevenly distributed across 7 chromosomes of C. sinensis and the promoter regions of these genes had multiple cis-acting elements related to hormone and stress responses. The collinearity analysis showed that there were 4 pairs of duplication events in the CsPLATZ gene family, all of which were segmental duplications. Based on this gene family, C. sinensis had a closer evolutionary relationship with A. thaliana than with O. sativa. The transcriptome analysis showed that the expression levels of CsPLATZ family members varied in different tissue samples of C. sinensis. 6 genes (CsPLATZ-1, CsPLATZ-2, CsPLATZ-3, CsPLATZ-4, CsPLATZ-6, and CsPLATZ-8) with high expression in shoots, young leaves, and roots were selected for high temperature and drought stress treatments, and their expression was quantified by qRT-PCR. The results indicated that the six genes might play important roles in the response to drought stress. In addition, CsPLATZ-2 and CsPLATZ-8 might have important functions in the response to high temperature stress. The results of this study will contribute to a better understanding of the biological functions of PLATZ genes and their possible roles in the growth, development, and stress responses of C. sinensis.

ObjectiveTo investigate the effect of dapagliflozin on liver lipid metabolism and gut microecology in mice with metabolic associated fatty liver disease （MAFLD）， and to clarify its potential mechanism. MethodsA total of 50 male C57 mice were randomly divided into Control group， type 2 diabetes+MAFLD group （MAFLD group）， dapagliflozin group （DAPA group）， meldonium group （THP group）， and dapagliflozin+meldonium group （DAPA+THP group）， with 10 mice in each group. High-fat diet combined with streptozotocin was used to establish a mouse model of MAFLD. Treatment outcomes were assessed based on histopathology and biochemical parameters such as blood glucose and blood lipid levels， and the transcriptomic and metagenomic analyses were used to identify differentially expressed genes and the changes in gut microbiota. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the least significant difference t-test was used for comparison between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups， and the Nemenyi test was used for comparison between two groups. ResultsHistopathological examination showed that the mice in the MAFLD group had excessive lipid deposition and hepatocyte steatosis； compared with the MAFLD group， the DAPA group had a significant improvement in hepatocyte steatosis， while the THP group and the DAPA+THP group had a less significant improvement compared with the DAPA group. Compared with the Control group， the MAFLD group had a significant increase in fasting blood glucose （P<0.05）， significant increases in the serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， malondialdehyde， total cholesterol， triglyceride， and low-density lipoprotein cholesterol （P<0.05）， and a significant reduction in high-density lipoprotein cholesterol （P<0.05）. Compared with the MAFLD group， the DAPA group， the THP group， and the DAPA+THP group had significant reductions in the serum levels of ALT and AST （P<0.05）. The results of 16S rRNA sequencing showed that compared with the Control group， the MAFLD group had significant changes in gut microbiota， with an increase in Firmicutes and a reduction in Bacteroidetes， as well as reductions in S24-7 and Erysipelotrichaceae and an increase in Lactobacillaceae. The levels of the above flora were upregulated to normal levels in the DAPA group， the THP group， and the DAPA+THP group. The liver transcriptomic analysis showed that the enriched metabolic pathways included steroid hormone biosynthesis， bile secretion， inflammatory mediator regulation of TRP， fatty acid elongation， and lipid biodegradation processes， and the related genes mainly involved the key targets of lipid metabolism such as Acot2， Angptl4， Scd2， and Npc1l1. ConclusionDapagliflozin can alleviate MAFLD through the pathways such as steroid hormone biosynthesis， bile secretion， inflammatory mediator regulation of TRP， and fatty acid elongation， as well as by regulating gut microbiota homeostasis.

Objective:To compare and analyze the efficacy of bilateral and unilateral posterior vocal cord resection with CO 2 laser under endoscopy in the treatment of bilateral vocal cord paralysis. Methods:This case series study retrospectively analyzed the data of 110 patients with bilateral vocal cord paralysis who underwent endoscopic CO 2 laser posterior cordotomy at the Department of Otolaryngology-Head and Neck Surgery, the First Affiliated Hospital of Naval Medical University, from October 2016 to January 2023. The cohort consisted of 36 males [mean age (45.5±9.1) years, range 24-72 years] and 74 females [mean age (47.2±10.1) years, range 22-67 years]. Among them, 47 patients underwent simultaneous bilateral posterior cordotomy (bilateral cordotomy group), while 63 patients underwent unilateral posterior cordotomy (unilateral cordotomy group). Pre-and postoperative indicators, including swallowing function, glottal size, and vocal function (subjective and objective assessments), were compared between the two surgical approaches. The Wilcoxon signed-rank test was used to analyze changes in swallowing function, glottal size, and vocal function (subjective and objective assessments) within each group before and after surgery, whereas the Mann-Whitney U test was utilized to assess differences between groups. Results:Postoperative follow-up was 1-5 years [median follow-up time was 1.6 (1.3, 2.0) years].The one-time extubation rate was 71.4%(45/63)in the unilateral posterior vocal cord resection group and 87.2%(41/47)in the bilateral posterior vocal cord resection group, significantly higher in the bilateral group ( χ2=3.94, P<0.05). One week after surgery, the swallowing function score of unilateral cordotomy group was 2 (1, 2.5) points, which was significantly better than that of bilateral cordotomy group [2 (1.5, 3) points, Z=-2.118, P<0.05], and the swallowing function score of both groups returned to normal 3 months after surgery. There were no significant differences in preoperative glottic closure during inhalation, auditory perceptual evaluation (GRBAS), objective voice analysis, and Voice Handicap Index-10 (VHI-10) between the two groups ( P>0.05). Postoperatively, the maximum transverse diameter of the posterior glottis during inspiration in the unilateral cordotomy group was 4.49 (4.24, 4.77) mm, significantly smaller than that in the bilateral cordotomy group, which was 5.05 (4.52, 5.62) mm ( Z=-4.103, P<0.05). Among the GRBAS parameters, G (grade of hoarseness), B (breathiness), and A (asthenia), as well as VHI-10 scores and objective voice analysis parameters [jitter, shimmer, harmonic-noise ratio (HNR), and maximum phonation time (MPT)], were significantly better in the unilateral cordotomy group compared to the bilateral cordotomy group, with statistically significant differences ( P<0.05). Conclusions:Unilateral posterior vocal cord resection using CO 2 laser is simple and feasible for the treatment of bilateral vocal cord paralysis, with shorter recovery time, maximal preservation of laryngeal phonatory function, and fewer complications compared to bilateral resection. However, the one-time extubation rate is higher with bilateral resection, reducing the need for a second surgery and associated patient discomfort. This study offers guidance for clinical decision-making in the surgical management of bilateral vocal cord paralysis.

Objective To establish the drug use evaluation(DUE)criteria for aspirin enteric-coated tablets and provide a reference for the rationally clinical application of aspirin enteric-coated tablets.Methods DUE criteria for aspirin enteric-coated tablets were established from three aspects of indications,medications and medication results with reference to drug instructions of aspirin enteric-coated tablets,related guidelines,expert consensus and literature,and through Delphi method.A retrospective analysis was conducted to evaluate the medical records of patients who took aspirin enteric-coated tablets from January 2021 to June 2022 in Fuqing Hospital affiliated to Fujian Medical University.Results A total of 1 071 medical records were included.683 cases fully met the DUE criteria,with a rational rate of 63.77％.Irrational drug use mainly included inappropriate indications(6.26％),off-label drug use without approval(28.48％),contraindications(1.03％),inappropriate usage and dosage(1.68％),drug interactions with potential clinical significance(0.65％)and other inappropriate drug use(2.71％).Conclusion The established DUE standard for aspirin enteric-coated tablets has strong scientific practicability and feasibility.The irrational rate of aspirin enteric-coated tablets in this hospital is high.Corresponding intervention measures should be formulated to ensure the safety of clinical medication.

Objective:To develop a risk prediction model of acute cerebral infarction (ACI) in patients with type 2 diabetes mellitus (T2DM).Methods:It was a cross-sectional study. The clinical data of 798 patients with T2DM hospitalized in the Department of Endocrinology and Neurology of Shanxi Bethune Hospital from August 2021 to October 2023 were collected. Based on whether they had concurrent ACI, the patients were divided into T2DM with ACI group (case group) and pure T2DM group (control group). The patients were then allocated to a training set ( n=558) and a validation set ( n=240) in a 7∶3 ratio by the sample functions in R software. LASSO regression was employed to screen and optimize variables, and a multivariate logistic regression analysis was used to establish the nomogram prediction model. The discriminative ability, calibration, and clinical usefulness of the risk prediction model were assessed with receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis, respectively. Results:LASSO regression identified gender, age, systolic blood pressure, fasting plasma glucose (FPG), albumin (ALB), and carotid vascular condition as the variables for prediction. The multivariable logistic regression analysis showed that female ( OR=0.489, 95% CI: 0.308-0.778) and ALB ( OR=0.846, 95% CI: 0.795-0.901) were protective factors for ACI occurrence in T2DM patients, while age ( OR=1.051, 95% CI:1.025-1.077), systolic blood pressure ( OR=1.047, 95% CI: 1.034-1.059), FPG ( OR=1.185, 95% CI: 1.089-1.288), and carotid plaque ( OR=7.359, 95% CI: 3.050-17.756) were risk factors. The area under the ROC curve (AUC) for risk of ACI in the training set was 0.863(95% CI: 0.833-0.893), and it was 0.846(95% CI: 0.797-0.896) for the validation set. Calibration curves and the Hosmer-Lemeshow goodness-of-fit test indicated good model fit (training set χ2=8.311, P=0.404; validation set χ2=3.957, P=0.861). Decision curve analysis showed that the clinical effectiveness of the model was higher when the threshold probabilities of the training set and the validation set was 0.02-0.93 and 0.12-0.99, respectively. Conclusion:In this study, a prediction model of ACI risk in T2DM patients was successfully established.

Objective:To understand the loss to follow-up of children born to pregnant women with HIV infection (HIV-exposed children) and analyze its influencing factors in China in 2019.Methods:The data were collected from the follow-up records of pregnant women with HIV infection and their children reported by the national "Management Information System for the Prevention of HIV, syphilis and Hepatitis B Mother-to-Child Transmission" in 2019. HIV-exposed children were defined as those who were not followed up after birth or who were not followed up at 18 months of age and who were not followed up at 21 months of age. The univariate and multivariate influencing factors of loss to follow-up of children born to HIV-infected pregnant women were analyzed by χ2 test and logistic regression model. SPSS 25.0 software was used for statistical analysis. Results:The number of HIV-infected pregnant women was 5 039, the number of live-born children was 5 035, the number of loss to follow-up children within 18 months of age was 283, and the loss to follow-up rate children was 5.62%(283/5 035). The results of multivariate logistic regression analysis showed that the rate of loss to follow-up of exposed children born to pregnant women who worked as farmers (animal husbandry and fishery) (a OR=0.34, 95% CI: 0.22-0.53), unmarried (a OR=0.47, 95% CI: 0.24-0.93), first marriage (a OR=0.38, 95% CI: 0.22-0.67), remarriage (a OR=0.36, 95% CI: 0.20-0.67) and cohabiting (a OR=0.47, 95% CI: 0.23-0.97), and knew they had HIV infection before this pregnancy (a OR=0.53, 95% CI: 0.40-0.70) was lower. Han nationality (a OR=1.52, 95% CI: 1.09-2.13), primary school (a OR=2.06, 95% CI: 1.10-3.89) and junior middle school (a OR=1.81, 95% CI: 1.03-3.17) educational level, non-use of antiviral drugs (a OR=6.21, 95% CI: 4.32-8.93) and delivery in township (street) level midwifery institutions (a OR=5.72, 95% CI: 1.61-20.27) had higher rates of loss to follow-up among infants born to HIV-infected pregnant women. Conclusions:HIV-exposed children still have a specific rate of loss to follow-up in China in 2019. In order to further reduce the rate of loss to follow-up, it is of great significance to improve the detection rate of HIV before pregnancy and the rate of antiviral drugs used in pregnant women with HIV infection, which is of great significance for the effective implementation of comprehensive intervention measures of prevention of mother-to-child transmission of HIV.

Recently,the substance P(SP)/neurokinin-1 receptor(NK-1R)system has been found to be involved in various human pathophysiological disorders including the symptoms of coronavirus disease 2019(COVID-19).Besides,studies in the oncological field have demonstrated an intricate correlation between the upregulation of NK-1R and the activation of SP/NK-1R system with the progression of multiple carcinoma types and poor clinical prognosis.These findings indicate that the modulation of SP/NK-1R system with NK-1R antagonists can be a potential broad-spectrum antitumor strategy.This review updates the latest potential and applications of NK-1R antagonists in the treatment of human diseases and cancers,as well as the underlying mechanisms.Furthermore,the strategies to improve the bioavailability and efficacy of NK-1R antagonist drugs are summarized,such as solid dispersion systems,nanonization,and nanoencapsulation.As a radiopharmaceutical therapeutic,the NK-1R antagonist aprepitant was originally developed as radioligand receptor to target NK-1R-overexpressing tumors.However,combining NK-1R antagonists with other drugs can produce a synergistic effect,thereby enhancing the therapeutic effect,alleviating the symptoms,and improving patients'quality of life in several diseases and cancers.
