ObjectiveTo investigate the influence of histone deacetylase 3 (HDAC3) on the occurrence, development of psoriasis-like inflammation in mice, and the relative immune mechanisms. MethodsHealthy C57BL/6 mice aged 6-8 weeks were selected and randomly divided into 3 groups: control group (Control), psoriasis model group (IMQ), and HDAC3 inhibitor RGFP966-treated psoriasis model group (IMQ+RGFP966). One day prior to the experiment, the back hair of the mice was shaved. After a one-day stabilization period, the mice in Control group was treated with an equal amount of vaseline, while the mice in IMQ group was treated with imiquimod (62.5 mg/d) applied topically on the back to establish a psoriasis-like inflammation model. The mice in IMQ+RGFP966 group received intervention with a high dose of the HDAC3-selective inhibitor RGFP966 (30 mg/kg) based on the psoriasis-like model. All groups were treated continuously for 5 d, during which psoriasis-like inflammation symptoms (scaling, erythema, skin thickness), body weight, and mental status were observed and recorded, with photographs taken for documentation. After euthanasia, hematoxylin-eosin (HE) staining was used to assess the effect of RGFP966 on the skin tissue structure of the mice, and skin thickness was measured. The mRNA and protein expression levels of HDAC3 in skin tissues were detected using reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB), respectively. Flow cytometry was employed to analyze neutrophils in peripheral blood and lymph nodes, CD4+ T lymphocytes, CD8+ T lymphocytes in peripheral blood, and IL-17A secretion by peripheral blood CD4+ T lymphocytes. Additionally, spleen CD4+ T lymphocyte expression of HDAC3, CCR6, CCR8, and IL-17A secretion levels were analyzed. Immunohistochemistry was used to detect the localization and expression levels of HDAC3, IL-17A, and IL-10 in skin tissues. ResultsCompared with the Control group, the IMQ group exhibited significant psoriasis-like inflammation, characterized by erythema, scaling, and skin wrinkling. Compared with the IMQ group, RGFP966 exacerbated psoriasis-like inflammatory symptoms, leading to increased hyperkeratosis. The psoriasis area and severity index (PASI) skin symptom scores were higher in the IMQ group than those in the Control group, and the scores were further elevated in the IMQ+RGFP966 group compared to the IMQ group. Skin thickness measurements showed a trend of IMQ+RGFP966>IMQ>Control. The numbers of neutrophils in the blood and lymph nodes increased sequentially in the Control, IMQ, and IMQ+RGFP966 groups, with a similar trend observed for CD4+ and CD8+ T lymphocytes in the blood. In skin tissues, compared with the Control group, the mRNA and protein levels of HDAC3 decreased in the IMQ group, but RGFP966 did not further reduce these expressions. HDAC3 was primarily located in the nucleus. Compared with the Control group, the nuclear HDAC3 content decreased in the skin tissues of the IMQ group, and RGFP966 further reduced nuclear HDAC3. Compared with the Control and IMQ groups, RGFP966 treatment decreased HDAC3 expression in splenic CD4+ and CD8+ T cells. RGFP966 treatment increased the expression of CCR6 and CCR8 in splenic CD4+ T cells and enhanced IL-17A secretion by peripheral blood and splenic CD4+ T lymphocytes. Additionally, compared with the IMQ group, RGFP966 reduced IL-10 protein levels and upregulated IL-17A expression in skin tissues. ConclusionRGFP966 exacerbates psoriatic-like inflammatory responses by inhibiting HDAC3, increasing the secretion of the cytokine IL-17A, and upregulating the expression of chemokines CCR8 and CCR6.

Objective:
To explore the intervention effect of schoolbased horticultural activities combined with fancy rope skipping on the health behaviour of fourthgrade primary school students, so as to provide a reference method for childrens health promotion.
Methods:
Eightyfive primary school students in grade 4 of a primary school in Changsha City were selected in March 2023 by using multistage cluster random sampling method and randomly divided into an intervention group (43 students) and a control group (42 students). The intervention group implemented a 12week comprehensive intervention of "schoolbased gardening combined with pattern skipping, once a week 90 min/time including routine practice (weeks 1-5,7-11; the contents were vegetable and plant management, theoretical knowledge learning of pattern skipping practice, etc.) and parent-child activities (weeks 6 and 12; vegetable salad making, synchronized jumping rope competition, etc.), and the control group maintained the regular curriculum. Moderate to vigorous physical activity (MVPA) and sleep duration were monitored by accelerometers in grade 4 primary school students, combined with questionnaires to assess fruit and vegetable intake and video screen behaviour, and generalised estimating equations were used to analyse the data.
Results:
After the intervention, there were interaction effect for school day MVPA time (Wald χ2group×time=8.27), vegetable intake (Wald χ2group×time=4.35), and video screen time (Wald χ2group×time=13.27) in both groups (P<0.01). After the intervention, the MVPA time in the intervention group increased from 30.00 (20.00,60.00) min to 40.00 (30.00, 60.00) min from school day; vegetable intake increased from 99.85 (33.95, 229.48) g to 190.15 (131.05, 279.48) g; and video screen time increased from 225.00 (110.00, 313.75) min to 60.00 (30.00, 142.50) min (Z=-4.51, -2.00, -3.84, P<0.05). However, there were no statistical differences in MVPA time, fruit intake and sleep time before and after intervention in the intervention group on weekends (Z=-1.35, -0.85, -0.24, P>0.05).
Conclusion
Schoolbased horticultural activities combined with an integrated intervention of fancy rope skipping can significantly improve physical activity, vegetable intake and video screen behaviours on weekdays in grade 4 primary school children, in order to provide a basis for multidimensional health promotion.

ObjectiveThis study aims to explore the effect of ultrasound-guided superficial parasternal intercostal plane block on the quality of recovery and postoperative analgesia in patients undergoing sternotomy cardiac surgery. MethodsA total of 64 patients undergoing sternotomy cardiac surgery were selected for this study. They were randomly divided into two groups: one group received a superficial parasternal intercostal plane block with ropivacaine (the ropivacaine group), while the other was given normal saline (the normal saline group). The primary outcome was the Quality of Recovery-15 (QoR-15) score on postoperative day 1 in both groups, accompanied by a comparative analysis of the pain score and opioid usage. ResultsCompared with the normal saline group, the ropivacaine group exhibited a significantly higher QoR-15 score on postoperative day 1[(89.60±13.24) vs (81.18±12.78), P=0.012]. The numerical rating scale at rest was significantly lower[(3.03±0.72) vs (4.26±0.93), P<0.001], and the numerical rating scale during coughing was also significantly reduced [(4.40±0.89) vs (5.44±1.05), P<0.001]. Concurrently, the cumulative morphine equivalent consumption during the initial 24 h postoperatively was significantly lower in patients who were administered the ropivacaine [14.15 (4.95~30.00) mg vs 40.50 (19.25~68.18) mg, P=0.002], and there was also a notable decrease in the rescue analgesia [0.00 (0.00~0.00) mg vs 0.00 (0.00~100.00) mg, P=0.007]. ConclusionUltrasound-guided superficial parasternal intercostal plane block can significantly enhance the overall quality of recovery in patients undergoing sternotomy cardiac surgery on postoperative day 1. The technique contributes to improved postoperative analgesic effects and a reduction in opioid usage, thereby facilitating early postoperative recovery.

To learn anxiety, depression, sleep quality and quality of life among patients with primary pruritus ani, and to analyze their correlation with anal itching symptom, so as to provide insights into the prevention and treatment of primary pruritus ani.
Methods:
Patients with primary pruritus ani were selected from anorectal department of the First Affiliated Hospital of Zhejiang Chinese Medical University. The Visual Analogue Scale, pruritus frequency score, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index and Dermatology Life Quality Index (Chinese version) were used in the survey. Spearman rank correlation analysis was employed to analyze the correlation between the degree and frequency of pruritus ani with, anxiety, depression, sleep quality and quality of life.
Results:
Sixty patients with primary pruritus ani were investigated, including of 7 males and 53 females, with an average age of (34.37±10.30) years. The patients with mild, moderate and severe pruritus accounted for 28.33%, 48.33% and 23.34%, respectively. The patients with pruritus frequency of grade 1, 2 and 3 accounted for 51.67%, 38.33% and 10.00%, respectively. The patients with anxiety, depression, and coexistence of anxiety and depression accounted for 18.33%, 13.33% and 10.00%, respectively. The patients with very good, good, average and poor sleep quality accounted for 15.00%, 46.66%, 30.00% and 8.34%, respectively. No, mild, moderate and severe impacts on quality of life among the patients accounted for 10.00%, 46.66%, 33.34% and 10.00%, respectively. The degree of pruritus was positively correlated with anxiety (rs=0.405, P=0.001), depression (rs=0.343, P=0.007), sleep quality (rs=0.293, P=0.037) and quality of life (rs=0.338, P=0.008). However, there was no significant correlation between the frequency of pruritus with the above factors (all P>0.05).
Conclusion
The degree of pruritus in patients with primary pruritus ani is related to anxiety, depression, sleep quality and quality of life.

ObjectiveBody fluid stains left at crime scenes are frequently trace amounts, while the identification of body fluids through real time fluorogenic quantitative technique often necessitates the repeated detection within the limited sample, as multiple miRNA markers are the basis for the identification. Based on the goal of both the throughput and efficiency improvement of miRNA analysis in trace samples, a duplex real time fluorogenic quantitative PCR assay system was designed to accurately quantify two miRNAs simultaneously, and the system should be further verified by actual sample for the body fluid identification. MethodsThe duplex real time fluorogenic quantitative PCR system of miR-451a to miR-21-5p was established with specially designed primers and probes, and the concentrations of the primers and probes were both optimized. The specificity, sensitivity and reproducibility of the system were validated, while its capability for body fluid identification was assessed using the miR-451a to miR-21-5p ratio. ResultsThe optimized assay system exhibited excellent specificity and repeatability, with coefficients of variation consistently below 8% for both intra- and inter-batch variability. The amplification efficiency of miR-451a and miR-21-5p reached 71.77% and 74.81%, respectively, with high and relatively consistent results. By utilizing this duplex real time fluorogenic quantitative PCR assay system, a total of 58 body fluid samples were analyzed, exhibiting a discrimination rate of 100% between blood and non-blood samples, as well as between peripheral blood and menstrual blood samples. Moreover, the results, obtained from single real time fluorogenic quantitative PCR assay system and duplex real time fluorogenic quantitative PCR assay system, showed no statistically significant difference with randomly selected blood samples (n=20). Compared to previous single real time fluorogenic quantitative PCR assay system, the sensitivity of duplex real time fluorogenic quantitative PCR assay system exhibited remarkable improvement. A minimum input of only 0.1 ng total RNA was sufficient for accurate detection of peripheral blood and menstrual blood samples, while saliva, semen, and vaginal secretion required only 1 ng total RNA for precise identification purposes. Additionally, the duplex real time fluorogenic quantitative PCR assay system successfully differentiated between different types of body fluids in simulated samples under natural outdoor conditions. ConclusionThe duplex real time fluorogenic quantitative PCR assay system effectively reduced both the time and material costs by half compared to the single system, especially suitable for the examination of body fluid stains left at crime scenes, solving the contradiction between the trace amount and the multiple sample volumes demand of repeated real time fluorogenic quantitative PCR. The duplex real time fluorogenic quantitative PCR assay successfully distinguished blood and other body fluid, as well as peripheral blood and menstrual blood samples, which maintains an equivalent capability for body fluid identification with half sample, time and reagent consumption. This system provides an efficient tool for identifying suspicious body fluids, as well as a foundation for more multiplexed real time fluorogenic quantitative PCR assay system research.

“Deficiency cause, cold accumulation, and qi stagnation” originates from Essentials from the Golden Cabinet (《金匮要略》), which is a guiding principle for the pathogenesis of women's diseases, pioneering the differentiation and treatment of women's diseases based on patterns, and having a profound influence on future generations. Following the classical principles and simplifying the complexities, this paper explored the pathogenesis and mechanism of polycystic ovary syndrome (PCOS) from the perspective of “deficiency cause, cold accumulation, and qi stagnation”, and believed that depletion of essence and blood, long-term accumulation of internal cold, and qi constraint and blood stasis are the causes of PCOS, with depletion of essence and blood, and lack of nourishment of zang-fu (脏腑) organs as the root, and cold pathogen invasion, qi constraint and blood stasis as the branch. The main treatment principle is “treating deficiency with supplementation”, and dispelling pathogen while reinforcing healthy qi, along with “treatment of cold by warming” and “treatment of stagnation by dispersing”. This is of great significance for the treatment of polycystic ovary syndrome. Clinically, these methods can be used flexibly to guide treatment and formula selection for PCOS, with the goal of harmonizing qi and blood and regulating menstruation.

ObjectiveTo analyse the clinical characteristics of different traditional Chinese medicine (TCM) syndromes in patients with heart failure based on information from electronic medical record. MethodsA cross-sectional study was conducted to collect clinical data of all inpatients with heart failure in the Department of Cardiology, Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from January 1, 2019 to December 31, 2020. A database of clinical TCM data was established to explore the characteristics of clinical data of basic information, syndromes and syndrome element types, and biochemical indexes. The distribution of TCM syndromes and syndrome elements in heart failure patients were also analysed, and the basic information and biochemical indexes of the patients with top 7 different TCM syndrome types were compared. ResultsA total of 1676 inpatients with heart fai-lure were included. The top 7 TCM syndromes of heart failure were syndrome of phlegm turbidity and blood stasis (477 cases, 28.46%), syndrome of qi deficiency and blood stasis (439 cases, 26.19%), syndrome of qi deficiency and blood stasis with water retention (274 cases, 16.35%), syndrome of yang deficiency with water retention (145 cases, 8.65%), syndrome of qi and yin deficiency (104 cases, 6.21%), syndrome of qi and yin deficiency with blood stasis (80 cases, 4.77%), syndrome of heart yang deficiency (59 cases, 3.52%). Among the 1676 patients, 6 syndrome elements accounted for more than 5%. Blood stasis accounted for the highest proportion of TCM syndrome element type (1292 cases, 77.09%), followed by qi deficiency (919 cases, 54.83%), phlegm (498 cases, 29.71%), water retention (434 cases, 25.89%), yang deficiency (215 cases, 12.82%) and yin deficiency (191 cases, 11.40%). Among the 1676 patients, 1308 cases of acute heart failure mainly showed syndrome of phlegm turbidity and blood stasis (386 cases, 29.51%), and 368 of chronic heart fai-lure mainly showed syndrome of qi deficiency and blood stasis (118 cases, 32.07%). Patients with syndrome of phlegm turbidity and blood stasis had the shortest disease duration of 0.3 months, while those with syndrome of heart yang deficiency had the longest disease duration of 15 months. The proportion of syndrome of phlegm turbidity and blood stasis was the highest in patients with heart failure combined with coronary artery disease, the proportion of syndrome of qi deficiency and blood stasis with water retention was the highest in patients with heart failure combined with atrial fibrillation, and the proportion of patients with syndrome of qi deficiency and blood stasis with water retention and syndrome of yang deficiency with water retention in those applying diuretics during the hospital stay was the highest with more than 86%. The different 7 TCM syndromes showed statistically difference in patients with complications including coronary artery disease, old myocardial infarction, atrial fibrillation, pre and post-admission medication usage including intravenous vasodilators, cardiac stimulants, diuretics, and level of blood chloride, blood urea, blood creatinine, blood bicarbonate, blood albumin, and blood total bilirubin (P<0.05). ConclusionThe most common TCM syndromes in patients with heart failure are syndrome of phlegm turbidity and blood stasis and syndrome of qi deficiency and blood stasis. Different TCM syndromes have different characteristics in gender, disease complications, medication before and after admission, and blood indexes.
