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.

There were 30 cross-sectional studies and 5 cohort studies; and 11 high-quality studies and 24 medium-quality studies. The meta-analysis showed that the demographic factors of lower level of education (OR=2.148, 95%CI: 1.711-2.696), lower economic income (OR=1.897, 95%CI: 1.589-2.264), male (OR=0.877, 95%CI: 0.782-0.985), living alone (OR=2.833, 95%CI: 1.756-4.569) and unmarried (OR=2.784, 95%CI: 1.251-6.196); the medication treatment factors of polypharmacy (OR=1.794, 95%CI: 1.190-2.706), potentially inappropriate medication (OR=2.988, 95%CI: 1.527-5.847), low frequency of daily medication (OR=0.533, 95%CI: 0.376-0.754) and adverse drug reactions (OR=3.319, 95%CI: 1.967-5.602); the disease factors of long course of disease (OR=2.118, 95%CI: 1.643-2.730), more comorbidities (OR=1.667, 95%CI: 1.143-2.431) and cognitive impairment (OR=2.007, 95%CI: 1.401-2.874); and the psychosocial factors of poor belief in taking medication (OR=1.251, 95%CI: 1.011-1.547), poor self-rated health (OR=1.990, 95%CI: 1.571-2.522) and being guided by healthcare professionals (OR=0.151, 95%CI: 0.062-0.368) were the influencing factors for medication compliance in patients with chronic comorbidities. Conclusion The medication compliance in patients with comorbidities of chronic diseases is associated with demographic factors, pharmacological factors, disease factors and psychosocial factors, mainly including living alone, adverse drug reactions, course of disease, number of comorbidities and medication beliefs.

BACKGROUND:The repair process of skin trauma is complex and susceptible to infection,easy to lead to poor healing,is the current difficulty and hot spot in wound repair research,and has received extensive attention in the fields of traditional Chinese medicine and tissue engineering. OBJECTIVE:To investigate the effect of moxibustion and reduced graphene oxide/cerium oxide nanocomposite on promoting the healing of infectious wounds. METHODS:(1)Reduced graphene oxide/cerium dioxide nanocomposites with mass ratios of 2:1,1:1 and 1:2 were synthesized by hydrothermal method.The resulting composites were recorded as G2C1,G1C1 and G1C2,respectively.The photothermal properties,cytotoxicity and antibacterial properties of the three kinds of materials were tested.After taking moxa sticks,three kinds of moxibustion distances were set(3.0-3.5 cm,recorded as moxibustion 1;2.5-3.0 cm,recorded as moxibustion 2;2.0-2.5 cm,recorded as moxibustion 3).Moxibustion was applied to the surface of human skin for 10 minutes to detect the photothermal properties.The antibacterial properties of moxibustion were tested at three different distance intervals.Simultaneously,the back body surface infrared imaging of rats with different mass concentrations of G1C1 material,moxibustion(three kinds of moxibustion distances)and moxibustion 2+G1C1 material was detected.(2)Sixty male Sprague-Dawley rats were selected to model the wound of Staphylococcus aureus infection.48 hours later,they were randomly divided into 10 groups with 6 rats in each group:control group(did not receive any treatment),mupirocin group,moxibustion 2+G1C1 group,moxibustion 1 group,moxibustion 2 group,moxibustion 3 group and 60,80,100,and 120 μg/mL G1C1 groups(The G1C1 group was given 808 nm near-infrared laser irradiation for 10 min/time,and the G1C1 suspension was loaded on the wound surface before each treatment.Each group of moxibustion underwent in-situ suspension moxibustion,and the intervention time was 10 min/time.Moxibustion 2+G1C1 group was loaded with G1C1 suspension on the wound surface before each treatment,and moxibustion was suspended in situ with moxa strips,and the intervention time was 10 min/time).The frequency of treatment was 2 days once.Wound healing,wound colony count and repair were detected after 7 days of intervention. RESULTS AND CONCLUSION:(1)The three kinds of reduced graphene oxide/cerium dioxide nanocomposites had good photothermal properties,and the higher the mass concentration of the composites,the better the photothermal properties.The temperature of the moxibustion 2 group reached 47.6 ℃for 10 minutes without causing thermal damage,which was more suitable for animal experiments.The results of co-culture with NIH-3T3 cells exhibited that 60,80,and 100 μg/mL G1C1 had good biocompatibility.The results of a co-culture experiment with Staphylococcus aureus suspension displayed that G2C1,G1C1 and G1C2 had good antibacterial activity,among which G1C1 group demonstrated excellent antibacterial performance,and the antibacterial rate reached 100％when its mass concentration was 80 μg/mL.60-120 μg/mL G1C1 could effectively remove Staphylococcus aureus biofilm,and the higher the material mass concentration,the better the removal effect.Moxibustion could also effectively remove Staphylococcus aureus biofilm,and the closer the moxibustion was,the better the removal effect.(2)Compared with the control group,the wound area of the mupirocin group,moxibustion 2 group,moxibustion 2+G1C1 group and 80,100 μg/mL G1C1 groups was significantly reduced on day 7 of treatment,and the quality of wound repair was better.Mupirocin,G1C1,moxibustion and moxibustion 2+G1C1 could effectively remove the residual bacteria on the wound surface,and the higher the mass concentration of G1C1,the lower the residual bacteria.Among them,the wound repair efficiency and bacterial residue of 80 μg/mL G1C1 group and moxibustion 2 group were very similar,and the wound repair efficiency of both was better than that of mupirocin group.In addition,it was also observed that the combination of materials and moxibustion had a better ability to clear wound bacteria than that used alone.(3)The results confirm that moxibustion,reduced graphene oxide/cerium dioxide nanocomposites and their combination have good anti-infection and wound healing effects.

Objective To establish the argatroban drug use evaluation(DUE)criteria and provide reference for the rational use of argatroban in clinical practice.Methods Based on the domestic and foreign drug instructions of argatroban,referring to relevant guidelines and literature,the DUE standard rules were established by expert consultation.Using the established standard rules,the medical records of argatroban in the Fuzhou First Hospital Affiliated with Fujian Medical University from August 2020 to August 2022 were evaluated for the rationality of medication.Results A total of 368 medical records were included,the rational rate of drug use was 48.64％,and the irrational drug use was mainly without indications(46.19％)and inappropriate combination of drugs(4.35％).Conclusion The rational rate of argatroban clinical use in the hospital is not high,and the problems mainly include off-indication drug use and unreasonable combination drug use.Through the establishment and clinical application of DUE standard rules,the clinical use of argatroban can be further standardized and the ability of rational drug use can be improved.

Objective To explore the potential categories and influencing factors of the fear of progression in patients with inflammatory bowel diseases(IBD).Methods IBD patients who received inpatient treatment in a tertiary hospital in Nanjing from July 2022 to July 2023 were selected as the study subjects by convenience sampling method.The General Demographic Information Questionnaire,the Chinese version of the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),the Chinese version of Inflammatory Bowel Disease Self-efficacy Scale(IBD-SES),and Social Support Rating Scale(SSRS)were administered to the participants.We applied one-way ANOVA and Logistic regression analysis to identify the factors associated with the potential categories of the fear of progression.Results A total of 303 retumed questionnaires(out of the 310)were valid,resulting an effective response rate of 97.74％.According to the results of latent profile analysis,we classified the respondents into 3 categories by the fear of progression,namely"low risk fear of disease adaptation group"(n=127,41.91％),"medium risk fear of illness distress group"(n=139,45.88％),"high risk fear of dysfunction group"(n=37,12.21％).3 groups showed statistically significant differences in permanent address,self-rated financial pressure,current disease status and self-efficacy(P＜0.05).Conclusion Patients with IBD had obvious differences in characteristics on the fear of progression.Nursing personnel should formulate personalized intervention strategies based on the classification characteristics of the fear of progression of IBD patients.Moreover,nurses should focus on improving patients'self-efficacy and promoting patients to treat medical care,stress and emotion management correctly.
