Objective To analyze the epidemiological and spatial clustering characteristics of varicella in Changzhou from 2018 to 2024, and to provide a theoretical support for the formulation of prevention and control measures. Methods The reported case information of varicella in Changzhou from 2018 to 2024 was collected through the China Information System for Disease Control and Prevention, and the three-dimensional distribution characteristics were analyzed. The incidence trend was analyzed by Joinpoint regression, and the spatial autocorrelation analysis was performed by Arc GIS 10.5 software. The spatiotemporal scanning analysis was carried out with SaTScan 10.1.2 software. Results From 2018 to 2024, a total of 42,132 cases of varicella were reported in Changzhou, with an average annual incidence of 116.25/100,000. The reported incidence showed a downward trend, with an annual percentage change (APC) of -21.96% (95%C1: -32.63%~-9.33%, P<0.01). The incidence showed a “bimodal distribution”, and the age group was mainly under 15 years old (29,086 cases, accounting for 69.04%). The difference in incidence between men and women was statistically significant (χ2= 92.83, P<0.001), and the incidence gradually decreased with age ( χ2trend=112771.44, P<0.001). Global autocorrelation analysis showed that there was spatial aggregation in the six years (P<0.05), and local autocorrelation analysis showed that most of the towns (streets) in the three central urban areas of Tianning District, Zhonglou District, and Xinbei District, as well as some towns (streets) in Liyang City, Wujin District, and Economic Development Zone were high-high aggregation areas. Spatiotemporal scanning analysis showed that the first type of aggregation area was most of the towns (streets) in Tianning District, Zhonglou District and Xinbei District (23, accounting for 92%), and some towns (streets) in Wujin District and Economic Development Zone (RR=3.76, P<0.001), and the second type of aggregation area was most of the towns (streets) in Liyang City (7, accounting for 70%) (RR=3.66, P<0.001). Conclusion The reported incidence of varicella in Changzhou City shows a downward trend, with multiple spatial and temporal clusters. The prevention and control of varicella in high-risk clustering areas, peak hours and high-risk populations should be strengthened, and intervention measures should be taken as soon as possible.

ObjectiveTo study the regulatory effects of Yinchenhao Tang combined with Yinchen Zhufu Tang on the expression of regulatory T (Treg)/helper T 17 (Th17) cells cultured in vitro from the patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). MethodsFresh peripheral blood was collected from the patients with HBV-ACLF for the separation of peripheral blood mononuclear cells (PBMCs). Immunomagnetic beads were used to isolate primary Treg and naive CD4+ T cells. After in vitro expansion, naive CD4+ T cells were induced to differentiate into Th17 cells. Rats were treated with the clearing method (Yinchenhao Tang), warming method (Yinchen Zhufu Tang), and combination of clearing method with warming method (Yinchenhao Tang combined with Yinchen Zhufu Tang, also known as Wenyang Jiedu Huayu Prescription), respectively, and then the medicated plasma samples were collected. Meanwhile, blank plasma was collected from the rats treated with normal saline. Cells were classified into blank, clearing method (5.04 g·kg-1), warming method (6.21 g·kg-1), and combination of clearing method with warming method (17.1 g·kg-1) groups and treated with corresponding plasma. The frequency of Treg/Th17 cells was detected by flow cytometry. The level of transforming growth factor-β (TGF-β) was measured by the enzyme-linked immunosorbent assay. The cytometric bead array (CBA) was employed to measure the levels of interleukin-10 (IL-10), interleukin-17A (IL-17A), tumor necrosis factor-α (TNF-α), and interleukin-23 (IL-23). The mRNA and protein levels of Forkhead box P3 (FoxP3) and retinoic acid-related orphan receptor-gamma t (ROR-γt) were determined by Real-time PCR and Western blot, respectively. ResultsCompared with the blank group, the combination of clearing method with warming method group showed decreased frequency of Treg and Th17 cells, lowered levels of Treg cytokines (TGF-β and IL-10) and Th17 cytokines (TNF-α, IL-17A, and IL-23), and down-regulated mRNA and protein levels of FoxP3 and ROR-γt (P<0.01). Compared with the clearing method group, the combination of clearing method with warming method group showed decreased Treg cell frequency and down-regulated mRNA and protein levels of FoxP3. Meanwhile, the combination group showed decreased Th17 cell frequency, lowered levels of TGF-β, IL-10, TNF-α, IL-17A, and IL-23, and down-regulated mRNA and protein levels of ROR-γt (P<0.05, P<0.01). Compared with the warming method group, the combination of clearing method with warming method group showed decreased frequency of Treg cells and down-regulated mRNA and protein levels of FoxP3. Meanwhile, the combination group showed decreased Th17 cell frequency, declined levels of TGF-β, IL-10, TNF-α, IL-17A, and IL-23, and down-regulated mRNA and protein levels of ROR-γt (P<0.05). ConclusionThe combination of clearing method with warming method can down-regulate the expression of specific cytokines of Treg and Th17 cells, inhibit the over activation of Treg and Th17 cells, and reduce the secretion of cytokines such as TGF-β, IL-10, TNF-α, IL-17A, and IL-23, thereby alleviating inflammation and improving the prognosis of the patients with liver failure.

ObjectiveTo investigate the differential expression of intestinal flora in patients with different traditional Chinese medicine (TCM) syndrome types (Yang Huang syndrome, Yin-Yang Huang syndrome, and Yin Huang syndrome) of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) and clarify the biological basis of jaundice and Yin Huang syndrome in liver failure. MethodsA total of 20 cases of HBV-ACLF patients were included in the Yang Huang group, 20 cases in the Yin-Yang Huang group, 16 cases in the Yin Huang group, and 20 healthy adult volunteers. 16S rRNA gene sequencing was used to detect the diversity, species distribution, and differences of the subjects' intestinal flora, and bioinformatics analysis was conducted. ResultsCompared with those in the healthy control group, the species richness and diversity of intestinal flora in the HBV-ACLF Yang Huang group, Yin-Yang Huang group, and Yin Huang group were significantly reduced, and there were significant differences in the composition of intestinal flora compared with healthy volunteers. However, there were no significant differences in the species richness, diversity, and composition of intestinal flora among the three groups. LEfSe analysis showed that compared with the healthy control group, the HBV-ACLF Yang Huang group showed significant enrichment of Staphylococcus aureus(P<0.01). Yin-Yang Huang group showed significant enrichment of s_Ileibacterium valens(P<0.05,P<0.01), and the Yin Huang group showed significant enrichment of Enterococcus faecium and Streptococcus sali varius(P<0.05). These strains may be biomarkers between the three groups of patients and the healthy control group. Compared with that in the Yin-Yang Huang group, Tyzzerella_nexilis was significantly enriched in the Yang-Huang group, and Streptococcus lactiae was significantly enriched in the Yin-Yang Huang group. Compared with that in the Yang-Huang group and the Yin-Yang Huang group, Enterococcus faecalis was significantly enriched in the Yin Huang group. The above strains may be biomarkers among the three groups of patients, and Enterococcus faecium may be a biomarker for the transition from the Yang Huang group to the Yin Huang group. ConclusionsThere are significant differences in the intestinal flora between patients with HBV-ACLF Yang Huang syndrome, Yin-Yang Huang syndrome, and Yin Huang syndrome. Enterococcus faecium is significantly enriched in the Yin Huang syndrome group, suggesting that dysbiosis of the intestinal flora may be the biological basis for jaundice and Yin Huang syndrome in liver failure.

Compared with that in the dampness-heat amassment syndrome group, the Treg/Th17 cell ratio decreased in the Qi-deficiency and stasis jaundice syndrome group, spleen-kidney Yang deficiency syndrome group, and liver-kidney Yin deficiency syndrome group (P<0.05). Compared with that in the Qi-deficiency and stasis jaundice syndrome group, the Treg/Th17 cell ratio increased in the spleen-kidney Yang deficiency syndrome group and liver-kidney Yin deficiency syndrome group (P<0.05). Compared with the spleen-kidney Yang deficiency syndrome group, the Treg/Th17 cell ratio in the liver-kidney Yin deficiency syndrome group increased (P<0.05). (3) Compared with those in the healthy control group, the levels of Treg-related cytokines IL-10 and TGF-β, as well as Th17-related cytokines TNF-α, IL-17A, and IL-23, were elevated in patients with various TCM syndrome types of HBV-ACLF (P<0.05). There was no significant difference in TNF-α levels among different TCM syndrome types. Compared with those in the heat-toxin amassment syndrome group, the levels of IL-10, TNF-β, IL-17A, and IL-23 in the dampness-heat amassment syndrome group, Qi-deficiency and stasis jaundice syndrome group, spleen-kidney Yang deficiency syndrome group, and liver-kidney Yin deficiency syndrome groups increased (P<0.05). Compared with those in the dampness-heat amassment syndrome group, the levels of IL-10, TGF-β, IL-17A, and IL-23 increased in the Qi-deficiency and stasis jaundice syndrome group, spleen-kidney Yang deficiency syndrome group, and liver-kidney Yin deficiency syndrome group (P<0.05). Compared with those in the Qi-deficiency and stasis jaundice syndrome group, the levels of IL-10, TGF-β, IL-17A, and IL-23 in the spleen-kidney Yang deficiency syndrome group increased (P<0.05), while those in the liver-kidney Yin deficiency syndrome group decreased (P<0.05).

Bronchial asthma (asthma) is a heterogeneous disease characterized by airflow limitation, airway remodeling, and recurrent symptoms such as wheezing, shortness of breath, chest tightness, and cough. Its prevalence is gradually increasing, and a portion of patients are still poorly controlled, leading to a serious social and medical burden. Modern studies have proposed the concept of the "lung-gut axis", which is based on the crosstalk between microorganisms and their metabolites in the lungs and large intestine, and have indicated that microbial dysbiosis in these organs may affect the onset and progression of asthma. Traditional Chinese medicine (TCM) has found the phenomenon of lung-intestinal comorbidity and put forward the importance of "lung-intestinal coordination therapy" in the treatment of lung-related diseases. It has been found that intestinal flora and their metabolites can modulate immune responses through the lung-gut axis, demonstrating great potential for predicting asthma susceptibility, anticipating phenotypes, assessing asthma severity, and guiding treatment. TCM comopunds that embody lung-intestinal coordination therapy, including herbal formulas, single herbs, acupuncture, moxibustion, acupoint application, and spinal pinching therapy, has been shown to regulate intestinal flora, improve metabolism, regulate immunity, alleviate lung inflammation, reduce mucus secretion, inhibit airway remodeling, effectively alleviate symptoms, and delay lung function decline. Based on "lung-intestinal coordination therapy", this paper used intestinal flora as the entry point to summarize the underlying mechanisms of TCM in asthma treatment and highlighted the pivotal role of intestinal flora in asthma, providing a new idea for its clinical treatment through the intestinal flora .

AIM: To investigate how angles kappa and alpha affect postoperative visual quality in patients with multifocal intraocular lens(mIOLs)implantation.METHODS: Retrospective cases series. A total of 46 patients(46 eyes)who underwent phacoemulsification were subsumed. The correlation between Preoperative angles kappa and alpha, wave-front aberrations and objective visual quality of cornea, internal, and total eye after surgery were analyzed using iTrace.RESULTS: The magnitude of angle kappa was negatively correlated with internal and total modulation transfer function(MTF)at 3 mm; the magnitude of angle kappa was positively correlated with astigmatism, trefoil, higher-order aberrations(HOAs)of both internal and total eye at 3 mm. The magnitude of angle alpha was negatively correlated with total MTF and total Strehl ratio at 3 mm. The magnitude of angle alpha was positively correlated with corneal coma at 5 mm, internal astigmatism at both 3 mm and 5 mm, and total spherical aberration(SA)at 3 mm. Multivariate linear regression analysis showed that, among candidate independent variables(kappa, alpha, astigmatism, SA, coma, trefoil, and HOAs), astigmatism is the only independent factor for altering corneal MTF at 3 mm and 5 mm; astigmatism and HOAs emerged as independent factors for altering internal MTF at 3 mm and 5 mm, and total MTF at 3 mm; astigmatism, SA and HOAs emerged as independent factors for altering total MTF at 5 mm.CONCLUSION: With greater preoperative angle kappa or angle alpha, patients who accept mIOL implantation tend to have larger internal astigmatism and HOAs, which resulting in poor visual quality, especially those with small pupil size.

AIM:To evaluate the characteristics of ocular biometric parameters and the distribution of corneal astigmatism(CA)in patients with high myopia before cataract surgery.METHODS:A prospective cross-sectional study was conducted, and 695 cataract patients(695 eyes)with high myopia [defined as an axial length(AL)≥26.00 mm] scheduled to undergo cataract surgery at our hospital from January 2022 to December 2024 were consecutively enrolled, another 695 cataract patients(695 eyes)with normal ALs(22.00 mm ≤AL≤25.00 mm)who underwent cataract surgery at our hospital during the same period were included in the control group. For patients with both eyes eligible, the right eye was used for analysis. Before cataract surgery, IOL Master 700 was used to measure the ocular biometric parameters of both eyes for each patient in the two groups. The medical records and ocular biometric data in the two groups were recorded and collected.RESULTS:There were no statistically significant differences between the two groups in genger, age, corneal diameter, and central corneal thickness(all P>0.05). In the high myopia group, the mean AL was 29.20±2.61 mm, and 252 eyes(34.1%)had AL ≥30.00 mm(extremely high myopia). The mean anterior chamber depth(ACD), lens thickness, vitreous chamber depth(VCD), CA, AL/corneal radius of curvature and VCD/AL in the high myopia group were 3.45±0.40, 4.41±0.47, 21.34±2.60 mm, 1.18±0.78 D, 3.79±0.38, and 0.73±0.03, respectively, which were all greater than those in the control group(all P<0.01). In the high myopia group, 350 eyes(50.4%)had CA ≥1.00 D, 192 eyes(27.6%)had CA ≥1.50 D, and 94 eyes(13.5%)had CA ≥2.00 D, which were all higher than those in the control group(32.8%, 15.1%, and 6.6%, respectively; all P<0.001). In the high myopia group, 87 eyes(12.5%)had flat corneas, 424 eyes(61.0%)had moderate CA, and 40 eyes(5.8%)had high CA. These proportions were all higher than those in the control group(6.0%, 46.9%, and 2.9%, respectively; all P<0.001). In the high myopia group, ACD and ACD/AL were negatively correlated with AL(r=-0.162 and -0.661, respectively; all P<0.001), while both ACD and ACD/AL in the control group were positively correlated with AL(r=0.338 and 0.105, respectively; both P<0.01). In the high myopia group, CA increased with age when the patient's age was ≥50 years(r=0.197, P<0.001), which was consistent with the control group.CONCLUSION: The standardized ocular biometric data of cataract patients with high myopia before cataract surgery are helpful for ophthalmologists to accurately calculate the intraocular lens(IOLs)power and select the appropriate IOL type. The majority of high myopia patients need simultaneous correction of CA during cataract surgery.

INTRODUCTION:
Health literacy plays an essential role in one's ability to acquire and understand critical medical information in the coronavirus disease 2019 (COVID-19) infodemic and in other pandemics. We aimed to summarise the assessment, levels and determinants of pandemic-related health literacy and its associated clinical outcomes.
METHODS:
A systematic review was performed in Medline ® , Embase ® , PsycINFO ® , CINAHL ® and four major preprint servers. Observational and interventional studies that evaluated health literacy related to the novel COVID-19, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) were included. Items used in health literacy instruments were grouped under the themes of knowledge, attitudes and practices. Determinants of health literacy were grouped into five domains: sociodemographic, medical, psychological/psychiatric, health systems-related and others.
RESULTS:
Of the 2,065 articles screened, 70 articles were included. Of these, 21, 17 and 32 studies evaluated health literacy related to COVID-19, SARS and MERS, respectively. The rates of low pandemic health literacy ranged from 4.3% to 57.9% among medical-related populations and from 4.0% to 82.5% among nonmedical populations. Knowledge about the symptoms and transmission of infection, worry about infection, and practices related to mask usage and hand hygiene were most frequently evaluated. Sociodemographic determinants of health literacy were most frequently studied, among which higher education level, older age and female gender were found to be associated with better health literacy. No studies evaluated the outcomes associated with health literacy.
CONCLUSION
The level of pandemic-related health literacy is suboptimal. Healthcare administrators need to be aware of health literacy determinants when formulating policies in pandemics.

This study explores the therapeutic differences and mechanisms of salt-processed Phellodendri Chinensis Cortex in improving insulin resistance(IR) based on network pharmacology, molecular docking, and cellular experiments. The components and intersection targets of Phellodendri Chinensis Cortex in improving IR were collected from databases, and a "drug-component-target-disease" network and protein-protein interaction(PPI) network were constructed to screen core components and targets. A total of 29 active components and 240 intersection targets were identified, of which 13 were core targets. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses were used to identify key signaling pathways, and molecular docking was performed to validate the binding activity between core components and targets. An IR model in HepG2 cells was induced using insulin combined with high glucose, and the effects of Phellodendri Chinensis Cortex before and after salt-processing on cell glucose consumption were evaluated. The expression of proteins related to the mitogen-activated protein kinase(MAPK) and phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT) signaling pathways was detected by Western blot. The cellular experimental results showed that, compared with the model group, glucose consumption in the drug-treated groups was significantly increased(P<0.01), the phosphorylation level of extracellular regulated protein kinase(ERK) was decreased(P<0.05), the phosphorylation levels of PI3K and AKT were increased, and the expression of glucose transporter 4(GLUT4) was also upregulated(P<0.05). Furthermore, the effect of salt-processed Phellodendri Chinensis Cortex was better than that of raw Phellodendri Chinensis Cortex. The study demonstrates that Phellodendri Chinensis Cortex, both before and after salt-processing, improves IR by regulating the expression of related proteins in the MAPK and PI3K-AKT signaling pathways, with enhanced effects after salt-processing.
