Objective:To explore the categories and characteristics of health behaviors of community residents in Dongfang City, Hainan Province, and to analyze the influencing factors of different categories.Methods:From March to May 2023, 795 community residents of Dongfang City were selected for the study using a simple random sampling method. General Information Questionnaire, Chinese version Short of Health Promotion Lifestyle Profile-Ⅱ, Health Conception Scale, and Self-rated Abilities for Health Practice Scale were used to conduct the survey. Cluster analysis was used to explore the health behavior categories of community residents, and a decision tree model was applied to analyze the influencing factors of different categories.Results:A total of 830 questionnaires were distributed, and 795 valid questionnaires were recovered, with a valid recovery rate of 95.78%. The health behaviors of 795 community residents in Dongfang City were divided into four categories of comprehensive behavior group (26.04%, 207/795), healthy behavior group (37.23%, 296/795), risky behavior group (18.99%, 151/795), and poor health behavior group (17.74%, 141/795). The decision tree model showed that exercise efficacy, gender, ethnicity, and clinical health concepts were the factors influencing different health behavior categories of community residents in Dongfang City ( P<0.05), with exercise efficacy being the core factor. Conclusions:There is heterogeneity in the health behavior of community residents in Dongfang City. Community healthcare workers can implement targeted health promotion measures according to the behavioral characteristics of the population.

The morbidity of gout is increasing year by year,and it has become a common and frequent disease.Once induced,the pain will reach its peak within 24 hours,which leading unsufferable pain to the patients.Buccal needling is a new micro-needling therapy created by Professor WANG Yongzhou's team,which was discovered and summarized in clinical practice of acupuncture after years of research.Buccal needling exerts certain efficacy in the treatment of acute gout.The progress of gout is related to the three levels of"body,qi and spirit".This paper discusses buccal needling in the treatment of acute gouty arthritis from the view of biological holographic theory,generalized triple energizer theory,and the theory of the integration of spirit and body,thus to provide certain reference for the further development of buccal needling in the treatment of pain-related diseases.

Objective To analyze the differences in aging-related information between Chinese and American drug instruction for common chronic disease in the elderly,and to propose policy recommendations for the aging-related drug instruction in China.Methods Ten common chronic disease treatment drugs for elderly patients were selected,and through the random sampling method,the drug manuals of one domestic manufacturer were randomly selected for each drug by the random number method,and one American drug manual was selected as a sample from the dailymed website,and the information related to elderly people in the various items of the drug manuals was statistically analyzed by using Excel for comparative analysis.The average reading level of the patient version of the U.S.drug instructions was calculated using the Readability Formulas Scoring System;the readability of the Chinese drug instructions was assessed by the Health Education Text Material Suitability Scale.Results Compared with the U.S.drug instruction,the drug instruction for common chronic diseases of the elderly in China were updated less frequently and at a slower pace;the drug instruction with information on medication for elderly patients were fewer than those of the U.S.drug instruction,and the content of the drug instruction was not well documented;and the drug instruction were poorly readable,which was not conducive to the comprehension of the elderly patients.Conclusion China is in urgent need of reforming the aging of drug instructions,and it is recommended that,for chronic disease medications for elderly patients,we should increase the number of clinical trials conducted on the elderly,improve and complete the drug information for the elderly in the drug instructions,and produce"drug instructions for elderly patients"that are suitable for the elderly to read and understand.

Objective This study is focused on ultrasound multimodality examination,which refers to the combined use of three ultrasound examination modalities,ultrasound(US),acoustic radiation force impulse(ARFI)imaging,and contrast-enhanced ultrasound(CEUS).The purpose of this study is to analyze the value of applying ultrasound multimodality examination in the differential diagnosis of benign and malignant breast non-mass-like lesions(NMLs).Methods Cases of breast NMLs were analyzed retrospectively,and the nature of all the lesions was verified by pathological examination.Based on the gray-scale ultrasound image characteristics,the cases were classified into types Ⅰto Ⅴ,and type Ⅰ and type Ⅱ were further classified into 4 subtypes,Ⅰa,Ⅰ b,Ⅱ a,and Ⅱ b,according to whether there was also calcification,and the proportion of malignant cases in each subtype was statistically analyzed.Logistic regression models of US,US+ARFI,US+CEUS,and US+ARFI+CEUS for the diagnosis of malignant cases were established,ROC curves were drawn,the area under the curve(AUC)was calculated,and comparisons were made accordingly.The detection rate of malignant NMLs without calcification(atypical malignant NMLs)by the combination examination of US,ARFI,and CEUS was analyzed.Results A total of 407 cases were included in the study.All subjects were female,aged 22 to 81 years,with the average age being(47.0±1 1.0)years.There were 220 benign cases and 187 malignant cases.Ranked from the highest to the lowest,the malignancy proportion of the different types wasⅠb＞Ⅱb＞Ⅲ＞V＞Ⅰa＞Ⅱa＞Ⅳ.The malignant proportion of the low echo area with calcification was significantly higher than that of the lesions without calcification.The AUC(95％confidence interval[CI])for diagnosing malignant cases with the logistic regression models of US,US+ARFI,US+CEUS,and US+ARFI+CEUS were 0.895(0.862-0.927),0.908(0.878-0.937),0.921(0.893-0.948),and 0.927(0.902-0.952),respectively.Comparison of the AUC of the 4 regression models showed significant differences(P＜0.001).The detection rate of US for NMLs without calcification was 80.7％.When US was used in combination with ARFI and CEUS,86.4％of the malignant NMLs lesions without calcification could be detected if the lesion CEUS score was 4 or 5 points or if shear-wave velocity(SWV)≥4.28 m/s.Conclusion Breast NMLs with calcification show high risks of malignancy,and a pathological examination is always recommended for a conclusive diagnosis.Ultrasound multimodality examination can improve the diagnostic accuracy of breast NML without calcification.

Background: There is still controversy whether the existence of esophageal heterotopic gastric mucosa (EHGM) and its histological type are related to the laryngopharyngeal symptoms. Aims: To analyze the clinical and histological characteristics of EHGM and its correlation with gastroesophageal reflux. Methods: A retrospective study was conducted in consecutive gastroscopy-proved EHGM cases from September 2018 to January 2020 at the Second Affiliated Hospital of Baotou Medical College. Besides clinical data review and questionnaire survey on reflux symptoms, histological typing of EHGM and immunohistochemistry were also performed in some cases. Results: A total of 1 229 cases of EHGM were recruited. The male-to-female ratio was 1.67:1, and middle-aged people were predominant. Most of the heterotopic mucosa were located 15-18 cm away from the incisors, and were mainly single. Two hundred and ninety-four cases (23.9%) were complicated with reflux esophagitis (RE), of which Los Angeles grade A and B accounted for 96.6%. Regurgitation/acid reflux (15.5 %) and heartburn (12.3%) were the most common esophageal symptoms, while extraesophageal symptoms were rare. Histological typing was obtained in 57 cases, of which, 37 (64.9%) were cardia-type, 18 (31.6%) were fundic-type, and 2 (3.5%) were mixed type. There were no significant differences in gender, age, location and number of EHGM, expression levels of H

OBJECTIVE: To study the influence of maternal sex chromosomal abnormalities on the prediction of fetal sex chromosome abnormalities (SCAs) by non-invasive prenatal testing (NIPT). METHODS: Thirty-six pregnant women with a prediction for fetal SCAs by NIPT were verified as false positive after prenatal diagnosis using amniotic fluid samples. With informed consent, these women were subjected to chromosomal karyotyping or copy number variations (CNVs) analysis through high-throughput sequencing. RESULTS: Sex chromosomal abnormalities were found in 8 women, which yielded an abnormal rate of 22.22% (8/36). Among these, 3 had sex chromosome aneuploidies (47, XXX), 4 had sex chromosome mosaicisms, and 1 carried structural chromosomal abnormalities. Reanalysis of the results of NIPT were consistent with the maternal CNVs by large. With the ratio of cffDNA (ChrX)/cffDNA was more than 2, 6 of the eight women were found to harbor sex chromosome abnormalities, and the fetal karyotype was normal. However, with a ratio of less than 2, only 2 of the 38 pregnant women had sex chromosome abnormalities, and 10 of the fetuses were confirmed as positive. CONCLUSION The presence of maternal sex chromosomal abnormalities can greatly influence the result of NIPT, which may also be an important reason for false prediction for fetal SCAs by NIPT. When NIPT indicates abnormal SCAs, it is necessary to analyze maternal sex chromosomes. The ratio of cffDNA(ChrX)/cffDNA may help to determine the source of abnormal signals.

Objective:To investigate the effect of management system on pregnancy outcome in patients with polycystic ovary syndrome (PCOS) of childbearing age.Methods:A total of 1203 patients with PCOS aged 20-45 years were collected in Reproductive Center of Zhongshan Boai Hospital from June 2016 to May 2018. Totally 755 who would like to be included in the long term management system were collected as study group and received basic blood pressure and weight control and serum monitoring, scientific education was performed through WeChat platform established for PCOS management and other methods. Other 448 patients with PCOS were not included in the long-term management system (control group), and their pregnancy outcomes were followed up.Results:The total pregnancy rate of study group was higher than that of control group (25.74% vs.18.13%, P=0.010), and the total abortion rate of study group was lower than that of control group (14.19% vs. 22.58%, P=0.199). Conclusion:Comprehensive management of PCOS patients of childbearing age can improve the public's cognition and acceptance of PCOS as a chronic disease, improve the compliance and pregnancy outcome of PCOS patients.
