OBJECTIVE: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pain in patients undergoing modified radical mastectomy for breast cancer. METHODS: A total of 140 female patients scheduled for unilateral modified radical mastectomy for breast cancer undergoing general anesthesia were randomized into a TEAS group (70 cases) and a sham TEAS group (70 cases, 2 cases dropped out). Patients in both groups received TEAS or sham TEAS at bilateral Neiguan (PC6), Zusanli (ST36), and Danzhong (CV17), respectively, from 30 min before anesthesia induction until the end of surgery, and on 1st, 2nd, and 3rd days after surgery for 30 min a time, once a day. On 1st, 2nd, and 3rd days after surgery, the pain visual analogue scale (VAS) score was observed; on 3, 6, 12 months after surgery, the incidence rate of chronic pain was observed; before surgery, and on 1st, 3rd, and 7th days after surgery, the serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10 were detected; the number of analgesia pump press, rescue analgesia, and the occurrence of adverse reaction after surgery were recorded in the two groups. RESULTS: In the TEAS group, the VAS scores on 1st and 2nd days after surgery, and the incidence rates of chronic pain on 3 and 6 months after surgery were lower than those in the sham TEAS group (P<0.05). On 1st, 3rd, and 7th days after surgery, the serum levels of TNF-α, IL-6, and IL-10 were increased compared with those before surgery in both groups (P<0.05, P<0.01); the above indexes in the TEAS group were lower than those in the sham TEAS group (P<0.05). The number of analgesia pump press and the incidence rate of rescue analgesia after surgery in the TEAS group were lower than those in the sham TEAS group (P<0.05). There was no statistically significant difference in the incidence of adverse reactions after surgery between the two groups (P>0.05). CONCLUSION TEAS can effectively improve both the postoperative acute pain and chronic pain in patients undergoing modified radical mastectomy for breast cancer, the mechanism may relate to inhibiting the inflammatory reaction.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Objective:To investigate the genotype and epidemiological characteristics of human metapneumovirus (HMPV) among hospitalized cases with acute respiratory infections (ARI) in children in Changchun City, Jilin Province, China.Methods:From June 2019 to June 2023, throat swabs of ARI inpatients in Changchun Children′s Hospital were collected, and their epidemiological and clinical information were also collected. Quantitative reverse transcription-PCR was used to identify HMPV-positive cases, followed by the amplification of the G gene and genetic analysis in the HMPV-positive cases.Results:A total of 3 311 children hospitalized with ARI were included in this study. Their age ranged from 0 to 17 years old, and the M ( Q1, Q3) of age was 2 (1, 3) years. About 1 811 (54.70%) cases were males. A total of 167 HMPV-positive cases were detected with a positive rate of 5.04%, of which 92.81% (155/167) were children under 5 years old. The positive rate of HMPV in 2019 was 6.37% (30/471), which dropped to the lowest in 2020 (2.31%, 10/432). The HMPV-positive rate was then rebounded in 2021 (4.70%, 60/1 277) and 2022 (4.56%, 21/461), which increased to 6.87% (46/670) in 2023. The difference in HMPV-positive rate among each year was statistically significant ( P<0.05). The prevalence peak of HMPV varied in different years, showing either a unimodal or bimodal distribution in one year. A total of 79 HMPV G gene sequences were obtained, of which subtype A and subtype B accounted for 48.10% and 51.90%, respectively. All of the subtype A sequences were clarified as A2c duplicated variants, and subtype B was mainly B2 genotype. Besides, subtypes A and B were prevalent alone or co-circulated in different years, and there was a subtype replacement pattern in HMPV. Conclusion:The positive rate of HMPV in hospitalized ARI cases in children is significantly different from 2019 to 2023 in Changchun City. Notably, there are certain switch patterns of HMPV subtypes A and B in different years.

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Background With urbanization and residential space expansion, ecological environment and human health issues have become hot social topics. Forest health, as a way of seeking health in nature, has begun to receive public attention in the context of the gradually increasing sub-healthy population and various psychological and physical diseases at a young age. Objective To systematically evaluate the effects of forest therapy on selected physical and mental health indicators. Methods Relevant research literature was retrieved from domestic and international databases (China National Knowledge Infrastructure, Wanfang Database, China Biomedical Literature Service System, Web of Science, ScienceDirect, PubMed, Embase, and Cochrane Library), with a time range from database establishment to January 31, 2023. Relevant data were extracted for meta-analysis to explore the relationship between forest therapy and selected psychological and physiological indicators. Results A total of 85 articles were included, and the meta-analysis results showed that better scores of Profile of Mood States, Positive and Negative Affect Scale, Beck Depression Inventory, and State Trait Anxiety Scale were found in the forest group than those in the urban group (P<0.05); the levels of systolic blood pressure, diastolic blood pressure, heart rate, sympathetic nerve indicator [ln (LF/HF)], salivary cortisol, and serum inflammatory factors were lower in the forest group than in the urban group, while parasympathetic nerve indicator [ln (HF)] level was higher in the forest group than in the urban group (P<0.05). The results of subgroup analysis showed that the changes in heart rate (SMD=−1.62, 95%CI: −2.41, −0.82), ln (HF) (SMD=1.29, 95%CI: 0.73, 1.85), ln (LF/HF) (SMD=−1.49, 95%CI: −2.13, −0.86), and salivary cortisol (SMD=−0.53, 95%CI: −0.81, −0.25) were more significant when the duration of forest therapy was ≤ 0.5 h, the recovery effect on emotional state was better in the >0.5~3 h group (such as tension SMD=−2.40, 95%CI: −3.21, 1.59), and the reduction effects on systolic blood pressure (SMD=−0.53, 95%CI: −1.03, −0.03) and diastolic blood pressure (SMD=−0.42, 95%CI: −0.88, 0.04) were better in the >3 h group. Seated meditation showed better recovery effects on multiple indicators of Profile of Mood States (such as fatigue SMD=−2.26, 95%CI: −3.07, −1.45), while walking showed better recovery effects on physiological indicators such as blood pressure (systolic blood pressure SMD=−0.57, 95%CI: −1.07, −0.06; diastolic blood pressure SMD=−0.72, 95%CI: −1.36, −0.07) and heart rate (SMD=−1.51, 95%CI: −2.38, -0.64). Except for blood pressure, the health benefits of forest therapy in the younger age group were generally better than those in the middle-aged and elderly group. Conclusion Relaxed and comfortable psychological feeling is reported when practicing forest therapy; it can lower blood pressure and heart rate, regulate the autonomic nervous system; it can also reduce the release of stress hormones and lower serum levels of inflammatory factors, exerting an auxiliary recovery effect on cardiovascular and immune system disorders. At the same time, the therapy duration, form, and age of the subjects have a certain impact on the effects of forest therapy practice.

Objective:This study comprehensively analyzed the genomic characterizations of human parainfluenza virus type 3 (HPIV3) strains circulating in six provinces and cities of China (Beijing, Henan, Jilin, Anhui, Gansu, and Shandong) during the period of 2019-2020. The aim was to elucidate the intricate genetic variations and molecular evolutionary trends within the HPIV3 genome.Methods:Based on genotypic differentiation, genetic divergence, and spatial and temporal distribution, 12 representative HPIV3 strains (including 7 of C3a subtype, 2 of C3b subtype and 3 of C3f subtype) were selected from the aforementioned provinces, and the complete genome sequence was successfully obtained by overlapping amplification of fragments using nested RT-PCR. Subsequently, a complete genome database of global representative HPIV3 strains was constructed and analyzed using bioinformatics tools.Results:The length of complete genome of the 12 HPIV3 strains in the present study varied between 15 227 bp and 15 370 bp, the G+ C content ranged from 35.1% to 35.3% and the nucleotide identity intermediated from 97.6% to 99.6%. Compared with the prototype strain (GenBank accession number: NC_001796.2), the nucleotide identity of 12 HPIV3 strains ranged from 94.2% to 94.5%. Analysis of the complete genome of HPIV3 available in China and globally showed that the genomic variation of HPIV3 was mainly shaped by substitution mutations, and no base deletions or gene recombination were observed.Only a six-base insertion (ATTAAA) was found in the F gene’s 3′UTR region of a representative strain originating from Jilin province (CHN/Jilin036/2019/C3b) in this study, and its potential pathogenic significance needs to be further investigated. Amino acid analysis of the encoded proteins revealed that the C3a lineage of HPIV3, widely prevalent both in China and worldwide, exhibits lineage-specific mutation sites in the N, P and L proteins. Furthermore, within the Chinese prevalent C3a strains, a distinctive mutation site (N216S) in L protein was also identified. Notably, specific variant sites have not been found in Chinese C3b and C3f branch strains. Based on the complete genome, the comprehensive evolutionary analysis showed that the time to the most recent common ancestor (tMRCA) of global HPIV3 strains was estimated to 1927 (95% HPD: 1901-1945), with an average molecular evolutionary rate of 5.29 × 10 -4 substitutions/site/year, while the average molecular evolutionary rate of HPIV3 strains in China is 5.24 × 10 -4 substitutions/site/year. In addition, each gene of HPIV3 was subjected to negative selection pressure, with the P, HN and F genes showing the most significant nucleotide variation and higher rates of molecular evolution than the other genes. Conclusions:This study reveals that the complete genome of HPIV3 strains circulating in six provinces and cities of China tend to evolve conservatively. Moreover, substitution emerge as the main driving force for molecular evolution of HPIV3.

Objective To investigate the effect of Guizhi Fuling Capsule on NF-κB and MAPK signaling pathway in lipopolysaccharide(LPS)-induced rat endometritis model.Methods The rats were randomly divided into 6 groups according to body weight,namely sham-operation group,model group,positive group(dexamethasone,2.5 mg·kg-1),Guizhi Fuling Capsule high-dose,medium-dose and low-dose groups(0.54,0.27,0.14 g·kg-1),with 10 rats in each group.The sham operation group and the model group were given 0.5%CMC-Na by gavage,and the other groups were given corresponding drugs by gavage once a day for 7 consecutive days.One hour after the last administration,the animals were anesthetized by intraperitoneal injection of 10%chloral hydrate.The rats in the sham operation group only underwent laparotomy and abdominal closure.The left uterus of the rats in the other groups was scratched and injected with a syringe(1.0 μg·μL-1)LPS normal saline solution 0.25 mL.24 hours after LPS injection,the uterine tissues of rats were collected and the pathological changes and MPO,TNF-α,IL-1β,IL-6 were measured in uterine tissues.The expression levels of NF-κB p65,IκBα,ERK,p38 and their phosphorylated proteins were measured in uterine tissues.Results Compared with sham operation group,histopathological score,MPO,TNF-α,IL-1β and IL-6 levels in model group were significantly increased(P<0.01),and NF-κBp65,IκBα,ERK,p38 protein phosphorylation levels were significantly increased(P<0.01).Compared with model group,Guizhi Fuling capsule significantly decreased pathological score of uterus,TNF-α,IL-1β,and IL-6 levels(P<0.01),and significantly decreased NF-κBp65,IκBα,ERK,p38 protein phosphorylation levels(P<0.01).Conclusion Guizhi Fuling capsule plays an anti-inflammatory role in endometritis by inhibiting the transmission of NF-κB and MAPK signaling pathways and inhibiting the secretion of inflammatory factors IL-1β,TNF-α and IL-6 in uterine tissue.

OBJECTIVES: During the coronavirus disease 2019 (COVID-19) pandemic, a growing prevalence of racial and ethnic discrimination occurred when many Americans struggled to maintain healthy lifestyles. This study investigated the associations of racial and ethnic discrimination with changes in exercise and screen time during the pandemic in the United States. METHODS: We included 2,613 adults who self-identified as non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, or Hispanic from the Health, Ethnicity, and Pandemic study, a cross-sectional survey conducted among a nationally representative sample of United States adults between October and November 2020. We assessed self-reported racial and ethnic discrimination by measuring COVID-19-related racial and ethnic bias and examined its associations with changes in exercise and screen time using multivariable logistic regression models. We analyzed data between September 2021 and March 2022. RESULTS: COVID-19-related racial and ethnic bias was associated with decreased exercise time among non-Hispanic Asian (odds ratio [OR], 1.46; 95% confidence interval [CI], 1.13 to 1.89) and Hispanic people (OR, 1.91; 95% CI, 1.32 to 2.77), and with increased screen time among non-Hispanic Black people (OR, 1.94; 95% CI, 1.33 to 2.85), adjusting for age, sex, education, marital status, annual household income, insurance, and employment status. CONCLUSIONS Racial and ethnic discrimination may have adversely influenced exercise and screen time changes among racial and ethnic minorities during the COVID-19 pandemic in the United States. Further studies are needed to investigate the mechanisms through which racial and ethnic discrimination can impact lifestyles and to develop potential strategies to address racial and ethnic discrimination as a barrier to healthy lifestyles.
