Objective: To analyze the characteristics of first-visit cases of herpes zoster in Zhoushan City, Zhejiang Province from 2021 to 2023, so as to provide the reference for improving herpes zoster prevention and control measures. Methods: Data on the incidence and vaccination of first-visit herpes zoster cases at all levels of public medical institutions in Zhoushan City from 2021 to 2023 were collected through the Zhoushan Comprehensive Health Information Platform and Zhoushan Immunization Program Information Management System. The incidence and outpatient proportion were calculated. The population distribution, seasonal distribution, and clinical consultation status of first-visit herpes zoster cases were described. Results: From 2021 to 2023, a total of 15 156 first-visit herpes zoster cases were reported in Zhoushan City, with an average annual incidence of 5.36‰. The incidences for each year were 5.78‰, 5.29‰ and 5.02‰, respectively, and the outpatient proportions were 0.15%, 0.14% and 0.11%, respectively, showed decreasing trends (both P<0.05). The number of doses of recombinant herpes zoster vaccine or live attenuated herpes zoster vaccine administered were 130, 312, and 633, respectively. The main consultation department was dermatology, with 11 004 cases (72.60%). The primary clinical diagnosis was visceral herpes zoster, with 5 901 cases (38.94%). A total of 1 936 cases (12.77%) had at least one underlying medical condition. The mean age of onset was (56.08±16.23) years, and the incidence showed an upward trend with increasing age (P<0.05). There were 7 386 male cases and 7 770 female cases, with a male-to-female ratio of 0.95∶1. The incidence among males aged ≥50 years was lower than that among females (6.53‰ vs. 8.69‰, P<0.05). The onset of the disease exhibited a significant seasonal pattern, with a peak period from June 21st to August 21st, covering 75% of the cases Conclusions From 2021 to 2023, the incidence and outpatient proportion of herpes zoster in Zhoushan City decreased. Summer was the peak season for onset, and women and the elderly were the key populations. It is necessary to strengthen the collaborative diagnostic and treatment capabilities of key departments such as dermatology and enhance the enthusiasm for vaccination among key populations.

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.

INTRODUCTION: Achieving low-density lipoprotein cholesterol (LDL-C) levels is key to preventing atherosclerotic cardiovascular events. However, many high-risk cardiovascular patients still experience poor LDL-C goal attainment and receive suboptimal lipid-lowering therapy (LLT) prescriptions. Herein, we evaluated LLT prescription patterns, LDL-C goal attainment and cardiovascular mortality among this population group in Singapore. METHODS: This prospective observational cohort study included 555 patients with ischaemic heart disease (IHD) admitted to the hospital in 2020. The LLT prescriptions, corresponding LDL-C levels and cardiovascular outcomes were assessed over a 24-month period. RESULTS: Most participants were male (82.3%), with 48.5% identified as Chinese. High-intensity statin prescriptions increased from 45.4% at hospital admission to 87.1% at discharge and remained stable at approximately 80% at 6, 12, and 24 months post-discharge. Combination LLT prescriptions increased from 12.3% at discharge to 33.8% by 24 months. Ezetimibe was the most commonly prescribed second-line LLT (40.8%), followed by inclisiran (1.09%) and anti-proprotein convertase subtilisin/kexin type 9 monoclonal antibody therapies (0.87%). Over 24 months, LDL-C goal attainment rates were 22.1% for LDL-C < 1.4 mmol/L and 47.2% for LDL-C < 1.8 mmol/L. Multivariable Cox proportional hazards regression indicated that achieving LDL-C < 1.8 mmol/L goal was associated with a reduction in all-cause mortality at 24 months (hazard ratio 0.53, 95% confidence interval 0.30-0.94, P = 0.030). CONCLUSION Treatment gaps in lipid management persist in 80% of the study population, indicating that statin monotherapy alone is insufficient to achieve LDL-C goals. Greater efforts to improve LDL-C goal attainment rates in high-risk cardiovascular patients are imperative.

Objective:To evaluate the application effect of non opioid anesthesia using ketamine in endoscopic submucosal dissection under general anesthesia of gastroscopy and laryngeal mask.Methods:Sixty patients who underwent elective endoscopic submucosal dissection under general anesthesia gastroscopy and laryngeal mask at Nanjing Medical University Affiliated Nanjing Hospital from January to December 2022 were randomly divided into a conventional anesthesia group and a non opioid anesthesia group using a random number table method, with 30 cases in each group. The conventional anesthesia group used opioid drugs, while the non opioid anesthesia group used ketamine instead of opioid drugs. We recorded the incidence of postoperative nausea and vomiting in two groups of patients; Recorded the mean arterial pressure (MAP) and heart rate (HR) of two groups of patients before anesthesia (T 0), during intubation (T 1), at the start of surgery (T 2), and after surgery (T 3); We also recorded the lowest pulse oxygen saturation (SpO 2) after extubation in two groups of patients; At the same time, the surgical time, propofol dosage, extubation time, monitoring time in the anesthesia and resuscitation unit (PACU), incidence of postoperative nausea and vomiting, patient satisfaction, and other adverse reactions were recorded. Results:The difference in surgical time, MAP and HR from T 0 to T 3, and the lowest SpO 2 after extubation between the conventional anesthesia group and the non opioid anesthesia group was not statistically significant (all P>0.05); Compared with the conventional anesthesia group, the non opioid anesthesia group had a lower incidence of postoperative nausea and vomiting, lower dosage of propofol, shorter extubation time and PACU monitoring time, and higher patient satisfaction (all P<0.05); Both groups of patients had no serious adverse reactions. Conclusions:The application of ketamine in endoscopic submucosal dissection during non opioid anesthesia of gastroscopy laryngeal mask has certain advantages over conventional use of opioid drugs, including fast postoperative recovery, low incidence of nausea and vomiting, and high patient satisfaction.

AIM To explore the effects and mechanism of Polygoni multiflori Radix Preparata(PMRP)ona rat model of post-stroke depression(PSD).METHODS The models of middle cerebral artery occlusion(MCAO)established by thread embolism method were then randomly divided into the model group,the positive drug(fluoxetine)group,and the low-dose and high-dose PMRP groups,with 10 rats in each group,in contrast to the 10 rats of the sham operation group.After 7 days of MCAO modeling,the rats underwent their 21-day PSD modeling except those of the sham operation group,during which the rats had their the neurological functions and behaviors assessed on the 1st,7th,14th and 21st day;and their cerebral infarction area and brain water content detected on the 21st day.HE staining,Nissl staining and immunohistochemical staining were used to observe the pathological morphology of cerebral ischemic penumbra.ELISA and Western blot were applied in the detections of the cerebral protein expressions of aquaporins(AQP3,AQP4,AQP5)and brain-derived neurotrophic factor(BDNF).RESULTS Compared with the model group,the high-dose PMRP group displayed improved neurological functions and behavioral scores(P＜0.05,P＜0.01),and reduced cerebral infarction area and brain water content(P＜0.05).Compared with the model group,each treatment group demonstrated clearer brain structure in ischemic penumbra,smaller intercellular space,increased neuron counts,decreased cerebral protein expressions of AQP3,AQP4 and AQP5(P＜0.05,P＜0.01),and increased BDNF protein expression(P＜0.05).CONCLUSION PMRP can reduce the depression of PSD rats by improving the microenvironment of neurons to promote their growth and survival,and eliminating the brain edema to enhance neurological functions via reduced protein expressions of AQP3,AQP4 and AQP5,and increased BDNF protein expression.

ObjectiveTo investigate whether there exists gender differences in mechanical pain hypersensitivity induced by the subcutaneous injection of macrophage colony-stimulating factor （M-CSF） in normal mice and to explore the preliminary mechanism. MethodsThirty 10-week-old C57BL/6J mice were randomly divided into three groups， (n = 10 mice/group, half male and half female). The albumin control group （BSA， 0.3 μg）， low dose M-CSF group （L M-CSF， 0.075 μg） and high dose M-CSF group （H M-CSF， 0.3 μg） received 50 μL BSA or M-CSF injected subcutaneously into the left medial thigh once daily for 3 consecutive days. Before and after drug administration， von-Frey mechanical sensitivity test was used to detect the mechanical paw withdrawal threshold （PWT） in each group. Immunofluorescence was performed to examine the expression changes of Ionized calcium-binding adaptor molecule 1 (Iba1) in skin， calcitonin gene-related peptide （CGRP） and phosphorylated ERK1/2 （p-ERK） in L5-L6 DRG and lumbar spinal dorsal horn. ResultsIn female mice， only high dose of M-CSF caused mechanical allodynia， whereas in male mice both doses produced marked allodynia. Mechanically， high-dose M-CSF induced massive aggregation of subcutaneous macrophages （marked by Iba1） in male and female mice， but more dramatic dependence in female mice. Similar gender differences were also found in the increase of p-ERK and CGRP expression in dorsal root ganglion （DRGs）. Notably， CGRP expression was especially elevated in the fibers of DRG in male mice. Correspondingly， the expressions of p-ERK and CGRP⁺ terminals in the superficial spinal dorsal horn of male mice were significantly higher than those of female mice after M-CSF treatment. ConclusionSubcutaneous injection of M-CSF triggers sexual dimorphism in mechanical pain hypersensitivity, which is related with differential changes in peripheral macrophage expansion and sensitization of the nociceptive pathway.

INTRODUCTION: Despite the challenges related to His bundle pacing (HBP), recent data suggest an improved success rate with experience. As a non-university, non-electrophysiology specialised centre in Singapore, we report our experiences in HBP using pacing system analyser alone. METHODS: Data of 28 consecutive patients who underwent HBP from August 2018 to February 2019 was retrospectively obtained. The clinical and technical outcomes of these patients were compared between two timeframes of three months each. Patients were followed up for 12 months. RESULTS: Immediate technical success was achieved in 21 (75.0%) patients (mean age 73.3 ± 10.7 years, 47.6% female). The mean left ventricular ejection fraction was 53.9% ± 12.1%. The indications for HBP were atrioventricular block (n = 13, 61.9%), sinus node dysfunction (n = 7, 33.3%) and upgrade from implantable cardioverter-defibrillator to His-cardiac resynchronisation therapy (n = 1, 4.8%). No significant difference was observed in baseline characteristics between Timeframe 1 and Timeframe 2. Improvements pertaining to mean fluoroscopy time were achieved between the two timeframes. There was one HBP-related complication of lead displacement during Timeframe 1. All patients with successful HBP achieved non-selective His bundle (NSHB) capture, whereas only eight patients had selective His bundle (SHB) capture. NSHB and SHB capture thresholds remained stable at the 12-month follow-up. CONCLUSION Permanent HBP is feasible and safe, even without the use of an electrophysiology recording system. This was successfully achieved in 75% of patients, with no adverse clinical outcomes during the follow-up period.

INTRODUCTION: The antinuclear antibody (ANA) test is a screening test for systemic autoimmune rheumatic disease (SARD). We hypothesised that the presence of anti-DFS70 in ANA-positive samples was associated with a false-positive ANA test and negatively associated with SARD. METHODS: A retrospective analysis of patient samples received for ANA testing from 1 January 2016 to 30 June 2016 was performed. Patient samples underwent ANA testing via indirect immunofluorescence method and anti-DFS70 testing using enzyme-linked immunosorbent assay. RESULTS: Among a total of 645 ANA-positive samples, the majority (41.7%) were positive at a titre of 1:80. The commonest nuclear staining pattern (65.5%) was speckled. Only 9.5% of ANA-positive patients were diagnosed with SARD. Anti-DFS70 was found to be present in 10.0% of ANA-positive patients. The majority (51/59, 86.4%) of patients did not have SARD. Seven patients had positive ANA titre > 1:640, the presence of anti-double stranded DNA and/or anti-Ro60. The presence of anti-DFS70 in ANA-positive patients was not associated with the absence of SARD (Fisher's exact test, p = 0.245). CONCLUSION The presence of anti-DFS70 was associated with a false-positive ANA test in 8.6% of our patients. Anti-DFS70 was not associated with the absence of SARD.
