Objective: To develop the Adolescent Peer Bullying Knowledge-Attitude-Practice (KAP) Questionnaire and to evaluate its reliability and validity, so as to provide an effective tool for evaluating the KAP level regarding peer bullying among adolescents. Methods: A preliminary framework was developed through literature review, expert consultation, and group discussions. In September 2024, 2 203 students in grades 7 to 9 from two regular junior high schools in Anhui Province were selected using cluster sampling for a preliminary survey aimed at questionnaire development, including item screening and reliability and validity testing. Results: The initial KAP questionnaire on adolescent peer bullying consisted of 25 items: two items, "Behavior 6" and "Behavior 7", were excluded as their correlation coefficients with the total KAP score being only 0.08 and 0.05, respectively, falling below the preset criteria(0.4). The final questionnaire comprised 23 items, divided into three dimensions: knowledge, attitude, and behavior. Reliability testing showed that the overall Cronbach α coefficient of the questionnaire was 0.89, with Cronbach α coefficients for the knowledge, attitude, and behavior dimensions being 0.91, 0.67 and 0.79, respectively. The overall splithalf reliability of the questionnaire was 0.87, with split half reliabilities for the knowledge, attitude, and behavior dimensions being 0.82, 0.64 , and 0.66, respectively. Testretest reliability ranged from 0.82 to 0.97. Confirmatory factor analysis results indicated that the questionnaire had RMSEA=0.062, NFI=0.924, CFI =0.931, with good discriminant validity. Conclusion The developed KAP questionnaire on adolescent peer bullying demonstrates good reliability and validity and can be used as an assessment tool for evaluating the KAP level regarding peer bullying among adolescents.

Objective: To evaluate the effectiveness of a family-school-community integrated intervention based on the microsystem theory in reducing peer bullying among junior high school students, so as to provide empirical evidence and feasible pathways for junior high school students bullying prevention and control in China. Methods: A combining convenience with clustering method was employed to select 6 268 students from three regular junior high schools in Fuyang and Anqing cities, Anhui Province, as the study subjects in October 2024, and randomly assigned by drawing lots to three groups: family-school-community integrated intervention ( n =2 063), school only intervention ( n =1 864), and control group ( n =2 341). From October 10, 2024, to January 10, 2025, the intervention was implemented for three months using posters, brochures, and videos, with one session every half month, each lasting 40 minutes. The family-school-community integrated intervention group received multi level interventions involving families, schools, and communities, while the school only intervention group received only school based interventions. The control group received routine school health education but no other interventions. Before and after the intervention, data on peer bullying among junior high school students were collected using the Peer Bullying Scale, and comparison of detection rate of peer bullying by Chi square test. Results: After the intervention,group comparison results showed that the incidence rates of various types of peer bullying in the family-school-community integrated intervention group, the school only intervention group, and the control group all showed statistically significant differences ( χ 2=28.61-66.85, all P <0.05). The detection rates of verbal bullying ( 7.51 %), relational bullying (5.62%), physical bullying (3.34%), cyberbullying (1.75%), being bullied (10.81%), verbal bullying others (2.67%), relational bullying others (1.55%), physical bullying others (1.36%), cyberbullying others (1.41%), and overall peer bullying (3.64%) in the family-school-community integrated intervention group were all lower than those in the control group (12.52%, 11.58%, 6.24%, 5.00%, 19.14%, 7.56%, 4.49%, 4.53%, 3.80%, 9.40%); additionally, the detection rates of verbal bullying others, overall peer bullying , verbal bullying, and being bullied , in the family-school-community integrated intervention group were all lower than those in the school only intervention group (4.67%, 6.65%, 13.14%, 16.42%), with statistically significant differences ( χ 2=30.04, 48.49, 19.75, 34.60, 58.89, 52.65, 31.32, 37.37, 24.14, 58.26; 11.25, 18.53, 33.93, 26.41, all P <0.016 7). Group comparison showed that in both intervention groups, the majority of peer bullying behaviors decreased after the intervention ( χ 2=4.86-171.01, all P <0.05). Conclusions The family-school-community integrated intervention based on the microsystem can effectively reduce peer bullying among junior high school students, with better efficacy than the single school intervention. The model can serve as a practical reference for establishing a multi level prevention and intervention system for junior high school students bullying in China.

The incidence and mortality rates of lung cancer remain high, making it the leading cause of cancer-related deaths. In women, the predominant histological subtype is lung adenocarcinoma, commonly associated with epidermal growth factor receptor (EGFR) mutations, and EGFR-tyrosine kinase inhibitors (EGFR-TKIs) can significantly improve patient prognosis. Metastasis of primary lung cancer to the endometrium is extremely rare and is often misdiagnosed as a primary reproductive system tumor, and its occurrence indicates poor prognosis. This article reports a case of an advanced lung adenocarcinoma patient with EGFR mutation, who developed abnormal vaginal bleeding after EGFR-TKIs treatment failure, and biopsy confirmed endometrial metastasis. A review of similar cases is also presented.

OBJECTIVE To conduct a reevaluation of the systematic review(SR)/meta-analysis on the use of Xianling gubao capsules(XLGBC)for knee osteoarthritis(KOA),and provide evidence-based support for the clinical use of the drugs.METHODS Computerized searches including CNKI,Wanfang Data,VIP,China Biomedical Literature Database,the Cochrane Library,PubMed,Embase and Web of Science were conducted to collect systematic reviews(SR)or meta-analyses of XLGBC for the treatment of KOA from the inception to May 31st,2024.The report quality,methodological quality,risk of bias and evidence quality were assessed using the PRISMA 2020 statement,AMSTAR 2 scale,ROBIS tool and GRADE tool,respectively.A comprehensive quality analysis of the quantitative results from the SR/meta-analysis was also performed.RESULTS A total of five SR/meta-analyses were included.The evaluation results based on the PRISMA 2020 statement showed that one study report was relatively complete(21 points),while four studies had deficiencies(18-20 points).The assessment using the AMSTAR 2 scale indicated that the methodological quality of all five studies was rated as very low.According to the ROBIS tool evaluation,the risk of comprehensive bias in all five studies was classified as high.GRADE tool evaluation revealed that among 49 outcome indicators,5(10.2％)were rated as moderate-quality evidence(10.2％),12 as low-quality evidence(24.5％),and 32 as very low-qualitv evidence(65.3％).The results of comprehensive quality analysis showed that the clinical efficacy,visual analogue scale score,pain relief time,comprehensive indexes of knee joint function,the levels of inflammatory factors and the incidence of adverse events in patients with XLGBC combined with conventional treatment were significantly better than conventional treatment alone(P＜0.05).CONCLUSIONS Compared with conventional treatment,XLGBC in combination with conventional treatment for KOA may have some efficacy and safety advantages.However,due to the low quality of evidence for the outcome indicators included in the studies,the conclusions should be interpreted with caution.

Abstract： Objective　To analyze the epidemiological characteristics of scrub typhus in Hainan Province from 2008 to 2023, forecast the epidemic trend in 2024, and provide a scientific basis for the prevention and control measures of scrub typhus in Hainan Province. Methods　The data of scrub typhus cases reported in Hainan Province from 2008 to 2023 were collected. Descriptive epidemiological methods were employed to analyze the temporal, spatial, and population distribution characteristics of scrub typhus. The simple moving average, seasonal decomposition, and seasonal autoregressive moving average (SARIMA) models were used to progressively deconstruct and analyze the epidemic patterns of scrub typhus in Hainan Province from 2008 to 2023 and predict its incidence trend in 2024. Results　A total of 4 300 scrub typhus cases were reported in Hainan Province from 2008 to 2023, with an average annual reported incidence of 2.75/100 000, and the annual reported incidence showed an increasing trend (Z=0.517, P=0.006). The population distribution characteristics were mainly among individuals aged 50-<70 years and those engaged in agriculture, forestry, fishery, and animal husbandry, with statistically significant differences (all P<0.001). There was an obvious seasonality in the temporal distribution, with cases primarily occurring from April to November, and peaking in October. In terms of regional distribution, the top four cities and counties with the highest cumulative reported cases were Qionghai City (826 cases), Wenchang City (558 cases), Chengmai County (486 cases), and Haikou City (452 cases), accounting for 54.00% of the total number of cases, and there were statistically significant differences in the number of reported cases among different cities (χ2=7 755.55, P<0.001). The SARIMA (1,0,2)(0,1,1)12 model fitted the incidence of scrub typhus in Hainan Province from 2008 to 2023 and predicted 364 cases in 2024, roughly equivalent to the number of cases in 2023. Conclusions　The incidence of scrub typhus in Hainan Province shows an overall increasing trend. Individuals aged 50-<70 years and those engaged in agriculture, forestry, fishery, and animal husbandry are the high-risk populations, with a prolonged peak incidence period. The number of predicted cases for 2024 is expected to remain consistent with 2023. Therefore, scientific interventions targeting high-risk populations before the peak incidence may improve the effectiveness of scrub typhus prevention and control.

Objective To investigate the impact of meteorological factors on rodent density in Hainan Province, and to provide scientific evidence for preventing and controlling rodent infestations and rodent-borne diseases in Hainan Province. Methods Data on rodent density and meteorological factors in Hainan Province from 2012 to 2022 were collected. Pearson's correlation or Spearman's rank correlation coefficients were used to analyze the relationship between rodent density and meteorological factors, and a generalized additive model was applied to assess the impact of meteorological factors on rodent density and their lag effects. Results From 2012 to 2022, the rat density in Hainan Province fluctuated between 1.96% and 4.32%, with an average density of 3.47%, showing no significant upward or downward trend (Ftrend=4.00, P=0.08). The brown rat was identified as the predominant rodent species in Hainan Province. Monthly average sunshine duration and monthly average precipitation impacted the current month's rodent density (P<0.05), with rodent density increasing with the growth of monthly average sunshine duration. When monthly precipitation was within 300 mm, rodent density remained relatively stable; however, with monthly precipitation between 300 and 500 mm, rodent density decreased with an increase in monthly precipitation, while exceeding 500 mm, monthly rat density showed an upward trend. Monthly average atmospheric pressure, sunshine duration, evaporation, precipitation, average temperature, and relative humidity all exhibited lag effects on rodent density (P<0.05). Rodent density lagged by one month decreased with an increase in average atmospheric pressure; rodent density lagged by three months initially decreased and then increased with an increase in monthly average sunshine duration, with a turning point at 150 hours; rodent density lagged by three months decreased with an increase in monthly evaporation; the impact interval of monthly precipitation on rodent density one month later was mainly between 200 and 300 mm; rodent density lagged by three months increased with temperatures rise but decreased steadily after 28 °C; rodent density lagged by one month decreased with an increase in relative humidity. Conclusions Monthly average sunshine duration and precipitation have certain effects on current month rat density, and monthly average atmospheric pressure, monthly sunshine duration, monthly evaporation, monthly precipitation, monthly average temperature, and monthly relative humidity all have lag effects on rodent density.

Abstract: Objective　To explore the tolerance of Aedes albopictus to typical insecticides and mutations in its knockdown resistance (kdr) and acetylcholinesterase number one (ace-1) genes in Hainan Province. Methods　Ae. albopictus larvae were collected from Danzhou, Sanya, Qiongzhong, Qionghai, Changjiang, and Wanning in Hainan Province in 2020 and 2021 to assess their resistance to 10 insecticides. Surviving samples from the resistance tests were examined for mutations in genes encoding acetylcholinesterase (AChE) and voltage-gated sodium channel (VGSC) using DNA Sanger sequencing. Results　The 24-hour corrected mortality rates of adult Ae. albopictus in different areas of Hainan to deltamethrin (0.03%), permethrin (0.40%), Beta-cypermethrin (0.40%), Beta-cypermethrin (0.08%), and lambda-cyhalothrin (0.07%) ranged from 5.56% to 83.33%, 29.89% to 92.22%, 26.67% to 97.78%, 11.11% to 88.89%, and 40.00% to 83.33%, respectively. The mortality rates after 24-hour exposure to propoxur (0.05%), bendiocarb (0.20%), malathion (0.50%), fenitrothion (0.20%), and chlorpyrifos (2.00%) ranged from 94.89% to 100.00%, among which the Ae.albopictus population from Changjiang showed a mortality rate of 97.78% to propoxur, and populations from Sanya, Wanning, and Qionghai showed mortality rates of 94.89%, 96.67%, and 96.67% to malathion respectively. The mortality rate of Ae.albopictus populations in Sanya and Qionghai to fenitrothion was 97.78%, while in other populations, it was 100.00%. Sequencing results showed that the kdr gene exhibited a mutation solely at locus 1534, featuring four alleles: wild-type TTC/F and the mutant types TGT(TGC)/C, TCC/S, and TTG/L with the mutation frequencies of 40.47%, 22.25%, 36.44%, and 0.85%, respectively. There are seven types of these mutations: wild-type homozygotes F/F, wild-type/mutant heterozygotes F/C, F/S, and F/L, mutant heterozygotes S/C, and wild-type homozygotes C/C and S/S, with mutation frequencies of 19.92%, 6.78%, 32.63%, 1.69%, 11.44%, 13.14%, and 14.41%, respectively. Notably, No related amino acid mutations were detected at position 119 of the ace-1 gene. Conclusions　The Ae.albopictus populations in various areas of Hainan Province have developed a high resistance to pyrethroid insecticides such as deltamethrin, permethrin, beta-cypermethrin, and beta-cyfluthrin, but are sensitive or possibly resistant to carbamates and organophosphates insecticides. The resistance gene mutations mainly occur at position 1 534 of the kdr gene, suggesting that its mutation frequency could be a significant factor contributing to resistance in Ae. albopictus in Hainan.

Abstract: Objective　To understand the level of Aedes aegypti resistance in Hainan and to provide a reference for developing local preventive and control measures against the dengue vector Ae. aegypti. Methods In 2020, Aedes aegypti larvae and pupae were collected from Danzhou and Changjiang in Hainan Province and reared to the first filial generation (F1). The adult mosquito contact tube method was used to determine the resistance of Aedes aegypti to commonly used insecticides. The allele-specific PCR (AS-PCR) was used to detect the mutations in V1016G and F1534C knockdown resistance (kdr) gene in Aedes aegypti. Results There was no significant difference in the knockdown rate of Ae. aegypti from Changjiang and Danzhou after 1 hour of exposure to four pyrethroids insecticides, namely deltamethrin (0.03%), permethrin (0.40%), beta-cypermethrin (0.04%) and lambda-cyhalothrin (0.02%). However, the 24-hour mortality rates of Ae. aegypti from Changjiang and Danzhou city were 95.56%, 85.56%, 81.11%, 48.89% and 94.44%, 68.60%, 61.11%, 30.00%, respectively. Except for deltamethrin (0.03%), the other differences were statistically significant. Aedes aegypti in Changjiang showed 100.00% mortality to propoxur (0.03%) and bendiocarb (0.20%), while in Danzhou, these rates were 100.00% and 98.89%, respectively. Ae. aegypti both from Changjiang and Danzhou showed 100.00% mortality to malathion (1.50%) and chlorpyrifos (0.80%), and mortality rates to 0.25% fenthion were 100.00% and 98.89%, respectively. V1016G and F1534C mutations were found in Ae. aegypti from Danzhou and Changjiang with mutation frequencies of 12.50% (20/160) and 97.50% (156/160), showing significant differences (χ2=233.54, P<0.001). In Changjiang, Aedes aegypti exhibited both V1016G and F1534C mutations with frequencies of 20.00% and 100.00%, respectively, whereas in Danzhou, only F1534C mutations occurred with a frequency of 98.75%. Conclusions Ae. aegypti in Hainan Province exhibited varying levels of resistance to four insecticides: deltamethrin, permethrin, beta-cypermethrin, and lambda-cyhalothrin, but showed sensitivity to propoxur, bendiocarb, malathion, and chlorpyrifos. The primary knockdown resistance gene mutation was F1534C.
