Objective To analyze the epidemiological characteristics and spatiotemporal clustering of varicella in Lu'an City from 2005 to 2023, and to provide a scientific basis for optimizing varicella prevention and control strategies. Methods Data on varicella cases were collected through the Chinese Center for Disease Control and Prevention Information System. Descriptive epidemiology, temporal trend analysis, seasonal analysis, spatiotemporal clustering analysis, and spatial autocorrelation analysis were conducted using QGIS, JoinPoint, SaTScan and GeoDa software. Results The average annual reported incidence rate of varicella in Lu'an City from 2005 to 2023 was 34.55/100,000, showing a trend of initial increase followed by a decrease. The peak incidence occurred from October to January of the following year (RR=1.97, LLR=1743.95, P=0.001). Students aged 0 to 19 was the primary affected group. Spatiotemporal scan analysis revealed four types of spatiotemporal clusters, with the cluster in Jin'an District from October 2017 to December 2023 being particularly prominent (RR=2.87,LLR=1734.15,P<0.001). Spatial autocorrelation analysis indicated significant clustering of varicella cases in the main urban area (Moran's I=0.216,Z=4.786,P=0.003). Conclusion The incidence of varicella in Lu'an City exhibits distinct seasonal and spatial clustering, and schools and kindergartens in the main urban area are the key to varicella prevention and control. It is necessary to enhance the monitoring of disease outbreaks during peak periods and in key areas, and to increase the two-dose vaccination rate for varicella in areas with case aggregation and among key populations.

OBJECTIVE:
Asthma imposes a significant global health burden. This study examines changes in the asthma-related disease burden from 1990 to 2021 and projects future burdens for 2050 under different scenarios.
METHODS:
Using data from the Global Burden of Disease 2021 study, we analyzed asthma incidence, prevalence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2021. We projected the disease burden for 2050 based on current trends and hypothetical scenarios in which all risk factors are controlled. Temporal trends in age-standardized incidence, prevalence, mortality, and DALY rates were explored using Annual Percent Change.
RESULTS:
In 2021, the age-standardized rates for asthma incidence, prevalence, mortality, and DALYs in China were 364.17 per 100,000 (95% uncertainty interval [ UI]: 283.22-494.10), 1,956.49 per 100,000 (95% UI: 1,566.68-2,491.87), 1.47 per 100,000 (95% UI: 1.15-1.79), and 103.76 per 100,000 (95% UI: 72.50-145.46), respectively. A higher disease burden was observed among Chinese men and individuals aged 70 years or older. Compared to the current trend, a combined scenario involving improvements in environmental factors, behavioral and metabolic health, child nutrition, and vaccination resulted in a greater reduction in the disease burden caused by asthma.
CONCLUSION
Addressing modifiable risk factors is essential for further reducing the asthma-related disease burden.

Objective:To assess the efficacy and safety of skin care products containing mandelic acid and niacinamide in the management of mild to moderate acne.Methods:A total of 50 patients with mild to moderate acne were prospectively enrolled at Xijing Hospital, Air Force Military Medical University, from June to October 2020. Participants were randomly assigned into an observation group and a control group using a random number table method, with each group comprising 25 individuals. The observation group consisted of 3 males and 22 females, with a mean age of (22.5±3.2) years; the control group also included 3 males and 22 females, with a mean age of (22.9±2.8) years. The control group received conventional acne treatment without any additional skin care interventions apart from daily facial cleaning; conversely, the observation group was treated with skin care products containing mandelic acid and niacinamide alongside standard treatment protocols. At weeks 2, 4, and 8 post-treatment, objective assessments utilizing skin property system and VISIA complexion analysis system were conducted to evaluate changes in lesion count as well as recovery of skin barrier function between both groups; additionally, patients completed adverse reaction record forms.Results:No significant differences were observed regarding gender distribution, age demographics, disease duration or severity between the two groups ( P>0.05). After 8 weeks of treatment, the rates of effective improvement for skin lesions and acne were observed to be 84.0% (21/25) in the observation group compared to 56.0% (14/25) in the control group for lesion improvement, and 84.0% (21/25) versus 44.0% (11/25) for acne improvement, respectively. When compared to the control group, the observation group demonstrated significantly higher rates of effective improvement in both skin lesions and acne ( P<0.001).VISIA analysis revealed that pore size scores as well as violet scores decreased significantly after eight weeks in comparison to controls ( P=0.035; P=0.027). CK results indicated reduced transepidermal water loss along with diminished sebum levels within the observation cohort relative to controls ( P=0.009; P=0.042). Skin erythema along with symptoms such as dryness or burning sensations occurred among five patients (three from the observation cohort while two belonged to controls) with no serious adverse reactions reported across either study arm. Conclusions:Skin care products incorporating mandelic acid and niacinamide can serve effectively as adjunctive treatments for mild-to-moderate acne with enhancing clinical outcomes accompanied by minimal adverse effects.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Background::Patients who undergo coronary artery bypass grafting (CABG) are known to be at a significant risk of experiencing long-term adverse events, emphasizing the importance of regular assessments. Evaluating health-related quality of life (HRQoL) serves as a direct method to gauge prognosis. Our objective is to ascertain the prognostic significance of consecutive HRQoL assessments using the Physical Component Summary (PCS) and Mental Component Summary (MCS) derived from the Short-Form 36 (SF-36) health survey in CABG patients.Methods::The study population consisted of 433 patients who underwent isolated elective CABG at Fuwai Hospital between 2012 and 2013. SF-36 assessments were conducted during both the hospitalization period and follow-up. The primary endpoint of the study was all-cause mortality, while the secondary outcome was a composite measure including death, myocardial infarction, stroke, and repeat revascularization. We assessed the relationships between the PCS and MCS at baseline, as well as their changes during the first 6 months after the surgery (referred to as ΔPCS and ΔMCS, respectively), and the observed outcomes.Results::The patients were followed for an average of 6.28 years, during which 35 individuals (35/433, 8.1%) died. After adjusting for clinical variables, it was observed that baseline MCS scores (hazard ratio [HR] for a 1-standard deviation [SD] decrease, 1.57; 95% confidence interval [CI], 1.07–2.30) and ΔMCS (HR for a 1-SD decrease, 1.67; 95% CI, 1.09–2.56) were associated with all-cause mortality. However, baseline PCS scores and ΔPCS did not exhibit a significant relationship with all-cause mortality. Notably, there was a dose-response relationship observed between ΔMCS and the likelihood of all-cause mortality (HRs for the 2nd, 3rd and 4th quartiles compared to the 1st quartile, 0.33, 0.45 and 0.11, respectively).Conclusions::Baseline MCS and changes in MCS were independent predictors for long-term mortality of CABG. Better mental health status and recovery indicated better prognosis.

Bronchopulmonary dysplasia(BPD)is a chronic respiratory system disease that causes respiratory failure and death in premature infants, and hyperoxic exposure is the main risk factor for its occurrence.Cellular senescence describes a state of cell cycle blockade, and in recent years studies have confirmed that exposure to hyperoxia can cause cellular senescence.Cellular senescence plays a crucial role in the development of the lung epithelium, lung interstitium, pulmonary vasculature, and airways, and abnormal development of these tissues is associated with the development of BPD.Therefore, this paper takes cellular senescence and BPD as the starting point to review the mechanism of hyperoxia-induced cellular senescence in the occurrence and development of BPD and the anti-aging drugs currently applied in clinical practice, in order to provide a new direction for the prevention and treatment of BPD.

Oxygen therapy is a common therapeutic method to improve oxygenation of premature infants, but long-term exposure to high oxygen can cause damage to immature organs and abnormal development.In addition to bronchopulmonary dysplasia and retinopathy, high oxygen levels will increase the risk of chronic kidney disease and hypertension in adulthood.High oxygen exposure can lead to kidney damage and developmental abnormalities in premature infants, including reduced number and increased volume of glomeruli, renal cell apoptosis, and abnormal development of renal tubules.The mechanism may be related to abnormal signaling pathways related to renal development.This article reviews the relationship between hyperoxia and kidney development and the possible mechanism of kidney disease, in an attempt to provide theoretical reference for early clinical intervention.
