Introduction: The contribution of the family environment to childhood obesity in Malaysia is not well known. This paper describes the study, methodology and results of a pilot study to assess the feasibility of conducting a study on diet and lifestyle factors among Malay primary school children and their main caregiver(s) in regard to body weight status.
Methods: The Family Diet Study used a cross-sectional design and targeted a minimum of 200 Malay families at five national primary schools in the Klang Valley, Malaysia using a multi-stage sampling method. Participants were Malay families with children aged 8 to 12 years and their main caregiver(s). Data on socio-demographic, dietary intake, parental child feeding practices, physical activity and anthropometric measures were collected predominantly at schools with follow-up 24-h dietary recalls collected by phone. Details of recruitment, inclusion criteria, assessments and statistical analyses are also discussed.
Results: Eleven families provided data by answering questionnaires, recalling diet intake and participating in anthropometric measures. The results showed overall feasibility of the study protocol but required some modifications prior to implementation of the main study. Mothers were the main parent involved in family food procurement, preparation and mealtime supervision. Snacking was not commonly reported and fruit and vegetables intakes were generally infrequent.
Conclusion: The most novel component of this study was the comprehensive collection of data from both children and their main caregiver(s) within the context of the family. Detailed information on dietary and lifestyle aspects will help to elucidate factors associated with obesity aetiology in Malay children.

OBJECTIVES:To determine the agreement between 1) ear examination findings of the otorhinolaryngologist using an otoscope and trained elementary school nurses using a penlight, 2) hearing screening findings of the otorhinolaryngologist and elementary school nurses, both using the Philippine National Ear Institute (PNEI) Method of 512 Hz Tuning Fork Test (TFT) and 3) PNEI Method of 512 Hz TFT findings and screening audiometry findings.
METHODS:In this continuing study, nurses residing in the venue of the study, and previously trained in ear examination using a penlight and hearing screening using the PNEI 512 Hz TFT, conducted these in school children who attended the hearing screening and medical mission. Otoscopy, PNEI Method of 512 Hz TFT, and screening audiometry were then conducted on the children by the otolaryngologist. The nurses and the otolaryngologist performed independent and blinded assessments.
RESULTS:Eighteen nurses and ninety children participated in the study. Data subjected to Kappa statistics showed good agreement between nurses and otorhinolaryngologist's findings in the examination of the external canal and tympanic membrane and in PNEI Method of 512 Hz TFTs, and between the PNEI Method of 512 Hz TFT and screening audiometry.
CONCLUSION:PNEI methods of penlight ear examination and 512 Hz TFT may be effective tools for early detection of common ear conditions and hearing screening in Filipino school children. These may be conducted in the school setting not only by otorhinolaryngologists but also by adequately trained school nurses.

Objective: To investigate the effect of heterogeneous nuclear ribonucleoprotein K (hnRNP K) and its interaction with human papillomavirus 16 (HPV16) on cervical intraepithelial neoplasia (CIN). Methods: The participants included 67 women with normal cervix (NC), 69 women with CINⅠ and 68 women with CINⅡ/Ⅲ in a community cohort of pathologically diagnosed women established in Jiexiu of Shanxi province, from June 2014 to June 2015. A structured questionnaire was used to collect the demographic data of the subjects and the related factors of cervical lesions. Cervical exfoliated cells and cervical tissues from biopsy or surgery were selected. The infection status of HPV16 was detected by flow-through hybridization. The protein expression levels of hnRNP K were evaluated by Western blot. SPSS 23.0 software was used to collate and analyze the data. To study the differences in demographic characteristics, related factors, hnRNP K protein and HPV16 infection among NC, CINⅠand CINⅡ/Ⅲgroups, χ(2) test, trend χ(2) test, and Kruskal-Wallis H test were conducted. Multiple comparisons of hnRNP K protein in three groups were completed by using the Bonferroni method. The OR and its 95%CI of hnRNP K, HPV16 and CIN were calculated by using the unconditional logistic regression models. Two-way interactions between hnRNP K protein and HPV16 infection on CIN were analyzed by using additive model and related indicators. Results: HPV16 infection rates were 10.4% in women with normal cervix, 14.5% in women with CINⅠ and 41.2% in women with CINⅡ/Ⅲ, respectively. The differences among three groups were significant (P<0.001). Moreover, the infection rates of HPV16 gradually increased with the increasing severity of CIN (trend χ(2)=18.512, P<0.001). The differences in protein expression of hnRNP K among three groups were significant (H=48.138, P<0.001) and the expressionincreased with the development of cervical lesionss (trend χ(2)=21.765, P<0.001). Results from the interaction analysis indicated that there were additive effects between high expression of hnRNP K protein and HPV16 in CINⅡ/Ⅲ group compared with normal group (API=0.639, 95%CI: 0.083-1.196). In contrast, no such additive effect was found in CINⅠ group. Conclusions: HPV16 infection and over-expression of hnRNP K protein were associated with the increased risk of cervical intraepithelial neoplasia. There might be interaction between hnRNP K protein overexpression and HPV16 infection existed on the progress of CINⅡ/Ⅲ.

Objective: To explore the relationship between abnormal expression of fragile histidine triad (FHIT) gene and methyl-CpG-binding protein 2 (MeCP2) as well as their interaction on cervical cancerization. Methods: A total of 73 patients with cervical squamous cell carcinoma (SCC), 113 patients with cervical intraepithelial neoplasia (CIN Ⅰ, n=45; CINⅡ/Ⅲ, n=68) and 60 women with normal cervix (NC) were included in the study. Real time PCR and Western blot were performed to detect the expression levels of mRNA and protein about FHIT and MeCP2, respectively. The methylation status of FHIT gene CpG island was tested by methylation-specifc PCR (MSP). Kruskal-Wallis H test, χ(2) test, trend χ(2) test and Spearman correlation analysis were conducted with software SPSS 20.0. The interaction was evaluated by generalized multifactor dimensionality reduction (GMDR) model. Results: With the deterioration of cervical lesion, the methylation rates of FHIT gene CpG island (χ(2)=18.64, P<0.001; trend χ(2)=18.08, P<0.001) increased gradually, while the expression levels of FHIT mRNA (H=27.32, P<0.001; trend χ(2)=12.65, P<0.001) and protein (H=47.10, P<0.001; trend χ(2)=29.79, P<0.001) decreased gradually. There was a negative correlation between the methylation rates of FHIT gene CpG island and the expression level of FHIT protein (r=-0.226, P<0.001). The levels of MeCP2 mRNA (H=26.19, P<0.001; trend χ(2)=11.81, P=0.001) and protein (H=69.02, P<0.001; trend χ(2)=47.44, P<0.001) increased gradually with the aggravation of cervical lesions. There was a positive correlation between the expression level of MeCP2 protein and the FHIT mRNA Ct ratio (r=0.254, P<0.001). Expression of proteins were negatively correlated between MeCP2 and FHIT (r=-0.213, P=0.001). The results analyzed by GMDR model showed that there were interactions among high MeCP2 protein expression, the CpG island methylation of FHIT and mRNA and protein expression in CINⅡ/Ⅲ group, and among high MeCP2 mRNA and protein expression, the CpG island methylation of FHIT and low mRNA and protein expression in SCC group. Conclusion: High expression of MeCP2 mRNA and protein, the CpG island methylation and low mRNA and protein expression of FHIT could increase the risk of cervical carcinogenesis, and there might be a synergistic effect on cervical carcinogenesis.

Objective: To study the prevalence and characteristics of overweight and obesity among Chinese children aged 0-5 years, in 2010-2013. Methods: Data was from the'China Nutrition and Health Surveillance-0-5-Years-Old Children and Lactating Women'project in 2013. Stratified multistage cluster sampling method was used to select 55 districts/counties from 30 provinces (autonomous regions, municipalities) with the sample size of children as 32 862. Definition of overweight and obesity were according to both the WHO 2006 growth standard in children less than 5-year-old and the WHO 2007 growth reference in children of 5-years-old. Results: were calculated by complex weight based on national census from the National Bureau of Statistics in 2010. Results The overall prevalence of overweight was 8.4% among the 0-5-year-old in 2013, with 9.4% in boys and 7.2% in girls. Both of the rates from urban and rural areas were the same, as 8.4%. The prevalence rates of overweight in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups appeared as 13.0%, 11.1%, 8.3%, 6.0%, 4.8%, 3.9% and 15.9%, respectively. The rates of overweight in low, medium and high income families were 8.0%, 8.8% and 8.9%, respectively. The prevalence of obesity was 3.1% among the 0-5-year-old, with 3.6% in boys and 2.5% in girls. There was no significant difference seen in urban (3.3%) and rural areas (2.9%). The prevalence rates for obesity in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups were 5.8%, 3.8%, 2.5%, 1.6%, 1.2%, 1.3% and 7.8%, respectively. The rates of obesity in low, medium and high income families were 2.8%, 3.3% and 3.5%, respectively. Conclusion: The prevalence rates of both overweight and obesity were increasing among the 0-5-year-olds in China, suggesting that it is necessary to timely conduct the surveillance and intervention programs on overweight and obesity in this target population.

7.Advances in recurrence risk assessment of gastrointestinal stromal tumor.
Chinese Journal of Gastrointestinal Surgery 2022;25(12):1138-1143
Identification of prognosis-related risk factors and accurate assessment of risk stratification in patients with gastrointestinal stromal tumor (GIST) is of great significance not only for establishing a reliable prognostic model and developing a follow-up plan but also for selecting potential populations benefiting from neoadjuvant therapies. Although several risk stratification models have been established, it is still challenging to accurately assess patients' risk of recurrence, and the performance of these prediction models still needs to be improved. This review focused on the latest studies in recurrence risk assessment for GIST patients, and summarized potential predictive markers and recurrence risk models related to tumor-related characteristic parameters, novel laboratory examinations, radiological imaging signatures and molecular pathological features, which could provide a reference for accurate risk stratification and individualized targeted therapies for GIST patients.

Objective: To optimize the warning threshold values of common communicable diseases in Gansu province, and improve the early warning effect. Method: An early warning model was set up for influenza, scarlet fever, other infectious diarrheal diseases, dysentery, typhoid and paratyphoid, viral hepatitis type E and hand foot and mouth disease (HFMD) respectively in Gansu by using the moving percentile method and cumulative sum method. By calculating the sensitivity, specificity, predictive value of positive test, predictive value of negative test, Youden' index and receiver-operating characteristic curve, the optimum early warning threshold values for communicable diseases in Gansu were selected. Results: The optimum early warning boundary values of influenza, scarlet fever, other infectious diarrheal diseases, dysentery, typhoid and paratyphoid, and viral hepatitis type E were P(90), P(80), P(95), P(90), P(80) and P(90) respectively. The optimum early warning parameters of HFMD were k=1.2, H=5σ. Under the optimum early warning boundary values/parameters, the early warning sensitivities of influenza, scarlet fever, other infectious diarrheal diseases, dysentery, typhoid and paratyphoid, viral hepatitis type E and HFMD were 86.67%, 100.00%, 91.67%, 100.00%, 100.00%, 100.00% and 100.00%, the specificities were 86.49%, 62.22%, 75.00%, 100.00%, 97.92%, 89.13% and 74.47%. The predictive values of positive test were 72.22%, 29.17%, 52.38%, 100.00%, 80.00%, 54.55% and 29.41%, and the predictive values of negative test were 94.12%, 100.00%, 96.77%, 100.00%, 100.00%, 100.00% and 100.00%, and the Youden' indexes were 0.73, 0.62, 0.67, 1.00, 0.98,0.89 and 0.74. Receiver-operating characteristic curve showed that the values/parameters of this warning boundary were the points closest to the upper left of the coordinate diagram. Conclusion: The early warning thresholds of influenza, other infectious diarrheal diseases, dysentery and hepatitis E in Gansu may be raised appropriately and the early warning parameters of HFMD need to be adjusted to improve the effectiveness of early warning.

Objective: To investigate the infection pattern and etiological characteristics of a case of human infection with highly pathogenic avian influenza A (H7N9) virus and provide evidence for the prevention and control of human infection with highly pathogenic avian influenza virus. Methods: Epidemiological investigation was conducted to explore the case's exposure history, infection route and disease progression. Samples collected from the patient, environments and poultry were tested by using real time reverse transcriptase-polymerase chain reaction (RT-PCR). Virus isolation, genome sequencing and phylogenetic analysis were conducted for positive samples. Results: The case had no live poultry contact history, but had a history of pulled chicken processing without taking protection measure in an unventilated kitchen before the onset. Samples collected from the patient's lower respiratory tract, the remaining frozen chicken meat and the live poultry market were all influenza A (H7N9) virus positive. The isolated viruses from these positive samples were highly homogenous. An insertion which lead to the addition of multiple basic amino acid residues (PEVPKRKRTAR/GL) was found at the HA cleavage site, suggesting that this virus might be highly pathogenic. Conclusions: Live poultry processing without protection measure is an important infection mode of "poultry to human" transmission of avian influenza viruses. Due to the limitation of protection measures in live poultry markets in Guangzhou, it is necessary to promote the standardized large scale poultry farming, the complete restriction of live poultry sales and centralized poultry slaughtering as well as ice fresh sale.

Objective: To analyze the reasons for the fluctuations in the percentage of outpatient or emergency visits for influenza-like illness (ILI) during the Spring Festival and National Day in 2014-2018 surveillance season. Methods: ILI surveillance data was collected during the period of Spring Festival and National Day in mainland China, and downloaded from Chinese Influenza Surveillance Information System, during the 2014-2018 surveillance season. Results: There was no significant difference noticed in the number of ILI reports in the festival week with weeks before or after in both the southern and northern provinces. The number of outpatient visits was much less than that of the week before and after, but the number of emergency visits was statistically significantly increased. Conclusion: In the holiday peak of ILI%, the major causes was the impact of holiday-off at sentinel hospitals, resulting in a large reduction in the number of outpatient visits in the consulting room during the festivals.
