Objective We investigated scoliosis incidence among junior high school students in Zhongshan city, Guangdong, China and the expression of miR-30e among those with scoliosis. Methods A total 41,258 students were included. From July 2015 to December 2017, all students underwent screening including routine observation of the standing and sitting posture, Adam's forward bend test, dorsal tilt angle measurement, and X-ray examination. Age, sex, height, weight, and body mass index (BMI) were recorded. Reverse transcription-quantitative polymerase chain reaction was used to assess miR-30e expression among students with scoliosis and 200 healthy students. Results Overall, 743 students were diagnosed with scoliosis, with an incidence rate of 1.80%. A total 646 (86.9%) students were diagnosed with idiopathic scoliosis, 38 (5.1%) with congenital scoliosis, and 59 (7.9%) with other scoliosis types. Compared with healthy students, height was significantly greater whereas weight and BMI were significantly lower among students with scoliosis, and expression of miR-30e was significantly lower. However, no significant difference was found in height, weight, BMI, and mean Cobb angle between high/low miR-30e groups. Conclusion The incidence rate for scoliosis was 1.80%, Compared with healthy students, those with scoliosis were taller, had lower weight and BMI, and miR-30e expression was significantly downregulated.

The purpose of this study was to analyze students in understanding ”faith in angels”. Also, the researchers tried to provide handouts with the example and non-example learning model and conventional model. This study employed the mixed-method approach, where the researchers used quantitative and qualitative data in formulating the results. The sample consisted of 68 junior high school students. The sample was determined by a total sampling of students studying Islamic Education at the Bengkulu school. The results showed that the concept of students' understanding of faith in angels was categorized as good. Furthermore, there is no significant difference between the use of the example and non-example model or the conversion model with handouts. The handouts made can make it easier to understand the concept of faith in angels even though they are used using the example and non-example and conventional model. The research with the handout of ”faith in angels” makes it easier for students to learn Islamic Education because it includes the picture and example real-life existence of angels.

Background: We performed an on-site cancer prevention educational program by oncologists focusing on all cancer types, and with emphasis on oral cancer. The program has been long-term supported by charity organizations of the Taiwan Total Cancer Care Foundation, and the Taiwan Cancer Total Care Information Society. Aim: To have a better understanding for cancer-related risk behaviors of our junior high school students in Taiwan, we performed a self-reported questionnaire survey before each educational activity. Methods: The questionnaire survey mainly focused on 3 cancer-related risk behaviors CBA [cigarette smoking (C), betel-nut chewing (B), alcohol drinking (A)], regarding the percentage of “frequent” CBA consumption, “ever-experience” of cancer-related risk behavior, starting time of risk behavior, sources of CBA, and existence of risk behavior among their parents/senior family members. Results: During 2016, 4,589 junior high school students received our on-site educational program whose questionnaires are valid for analysis. Among them, 4,097 and 492 students are from western and eastern towns. Taiwan is geographically divided by the high-altitude Central Mountains into western and eastern towns. Western towns are relatively more urban, while eastern towns are more rural in both industrial and economic development. Questionnaires from 7th, 8th, 9th grade of junior high school students represent 37.1%, 44.0%, and 18.9%. The average body mass index (BMI) is 20.68 and 21.47 in western and eastern towns, respectively. The average BMI of boy students between western & eastern towns shows statistically significant difference of 21.87 (eastern) and 21.01 (western), respectively ( P = 0.005, Pearson χ2), while the average BMI of girl students has only a trend to be higher in eastern towns (20.82) than that in western towns (20.30) ( P = 0.072). The percentage of “frequent” (daily, or 2-6 days per week) consumption of C, B, and A is 2.7%, 0.6%, and 1.3%, respectively. The percentage of “frequent” C consumption shows statistically significant higher in eastern (4.5%) than western (2.5%) towns ( P = 0.009), the percentage of “frequent” B consumption also shows statistically significant higher in eastern (1.6%) than western (0.5%) towns ( P = 0.003). However, the percentage of frequent A consumption has no significant difference between western (1.2%) & eastern (1.8%) towns ( P = 0.257). The percentage of “ever-experience” of A is significantly higher in eastern (5%) than western (3%) towns ( P = 0.001), while the percentage of ever-experience of C has no significant difference between eastern (9%) & western (7%) towns ( P = 0.257), the percentage of ever-experience of B also has no significant difference between eastern (16%) & western (15%) towns ( P = 0.751). Conclusion: Self-reported survey for junior high school students on cancer-related risk behaviors, CBA, revealed that frequent cigarette smoking (C) is the most prevalent (2.7%) one among CBA in Taiwan.
