[Risk assessment of nonylphenol exposure in vegetable oil of residents in six cities of Shandong Province in 2014-2015].

OBJECTIVE: To investigate the level of nonylphenol dietary exposure in vegetable oils of 6 cities in Shandong Province and to evaluate the contribution of risk. METHODS: The data of Total Dietary Study and Health Status Survey of Shandong Province and nonylphenol test data were used to evaluate the exposure. A total of 3468 people from6 cities of Shandong province were selected for food survey by stratified multistage cluster random sampling method in 2014-2015. The consumption of vegetable oil was investigated by weighing and accounting method. Nonylphenol content in dietary samples was detected by high performance liquid chromatography-mass spectrometry( HPLC-MS). RESULTS: The exposure level of nonylphenol in vegetable oil was 0-0. 44 µg/kg, and the risk index of the highest point of exposure was 0. 088. CONCLUSION: Risk caused by vegetable oil intake of nonylphenol in Shandong Province 6 city residents is extremely low.

Prevalence of severe obesity and its association with elevated blood pressure among children and adolescents in Shandong, China.

BACKGROUND: Childhood obesity has increased markedly during the past decades; however, data on the prevalence of severe obesity in children and adolescents are limited. The present study examined the prevalence of severe obesity and its association with elevated blood pressure (BP) among children and adolescents in Shandong, China. PATIENTS AND METHODS: A total of 44 630 (22 404 boys and 22 226 girls) students aged 7-18 years participated in the study. BMI cut-off points recommended by the International Obesity Task Force were used to define class I-III obesity. Relatively high BP status was defined as systolic BP and/or diastolic BP of at least 95th percentile for age and sex. RESULTS: The prevalence rates of class I, class II, and class III obesity were 6.67, 1.47, and 0.42% for boys and 2.88, 0.64, and 0.18% for girls, respectively; boys had a higher prevalence than girls (P<0.01). Substantial urban-rural disparities exist in childhood obesity; urban boys and girls had a higher prevalence of class I and class II obesity than their rural peers (P<0.05). Severe obesity is associated with elevated BP; the prevalence of relatively high BP increased from 39.93% (boys) and 39.53% (girls) in the class I obese group to 50.54% (boys) and 53.66% (girls) in the class III obese group (P<0.05). CONCLUSION: Although the current prevalence of severe obesity was at a relatively low level, but we should not relax our vigilance to the obesity epidemic. Our findings also emphasize the importance of the prevention of severe obesity to prevent future-related problems such as hypertension in children and adolescents.

Nutritional therapy and effect assessment of infants with primary intestinal lymphangiectasia: Case reports.

RATIONALE: Intestinal lymphangiectasia (IL) is a rare enteropathy involving the expansion and rupture of intestinal lymphatic channels. Although several reports have studied cases of primary IL (PIL), this condition is very rare, and is even less commonly encountered in infants. This study aimed to investigate the nutritional therapy and effect assessment of chylous reflux disorder caused by PIL in infants. PATIENT CONCERNS: Infantile patients were enrolled in the Affiliated Beijing Shijitan Hospital of the Capital Medical University between January 2012 and March 2014. The minimum age of onset was 4 months and the maximum age of onset was 16 months, with an average age of 4.9 months. DIAGNOSES: All children were inpatient who had been diagnosed with chylous reflux syndrome (chylothorax and/or chylic abdomen) caused by PIL. INTERVENTIONS: Retrospective analysis and individualized nutrition therapy of these cases were carried out. Finally, nutritional therapy and prognosis of PIL were assessed and summarized. OUTCOMES: All the children survived, showed improvement in the serum total protein, albumin, and HGB levels after nutritional therapy. After comprehensive nutritional therapy, we were able to achieve diarrhea control for all the 9 patients, and after treatment, the children passed soft, yellow stools 1 to 2 times/d. After treatment, the height and weight of all patients increased to within the normal ranges of the World Health Organization standard chart. The mean serum albumin level reached 41.3 g/L. All nutrition-related indicators were found to have significant improvement compared with the baseline levels. LESSONS: The results revealed that nutritional therapy for the 9 children with PIL was effective, and it may be able to improve the clinical syndromes and symptoms of children with PIL and promote recovery.

Concentrations and health risk assessment of rare earth elements in vegetables from mining area in Shandong, China.

To investigate the concentrations of rare earth elements in vegetables and assess human health risk through vegetable consumption, a total of 301 vegetable samples were collected from mining area and control area in Shandong, China. The contents of 14 rare earth elements were determined by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The total rare earth elements in vegetables from mining and control areas were 94.08 µg kg-1 and 38.67 µg kg-1, respectively, and the difference was statistically significant (p < 0.05). The leaf vegetable had the highest rare earth elements concentration (984.24 µg kg-1 and 81.24 µg kg-1 for mining and control areas, respectively) and gourd vegetable had the lowest rare earth elements concentration (37.34 µg kg-1 and 24.63 µg kg-1 for mining and control areas, respectively). For both areas, the rare earth elements concentration in vegetables declined in the order of leaf vegetable > taproot vegetable > alliaceous vegetable > gourd vegetable. The rare earth elements distribution patterns for both areas were characterized by enrichment of light rare earth elements. The health risk assessment demonstrated that the estimated daily intakes (0.69 µg kg-1 d-1 and 0.28 µg kg-1 d-1 for mining and control areas, respectively) of rare earth elements through vegetable consumption were significantly lower than the acceptable daily intake (70 µg kg-1 d-1). The damage to adults can be neglected, but more attention should be paid to the effects of continuous exposure to low levels of rare earth elements on children.

Assessment of successful smoking cessation by psychological factors using the Bayesian network approach.

The association between psychological factors and smoking cessation is complicated and inconsistent in published researches, and the joint effect of psychological factors on smoking cessation is unclear. This study explored how psychological factors jointly affect the success of smoking cessation using a Bayesian network approach. A community-based case control study was designed with 642 adult male successful smoking quitters as the cases, and 700 adult male failed smoking quitters as the controls. General self-efficacy (GSE), trait coping style (positive-trait coping style (PTCS) and negative-trait coping style (NTCS)) and self-rating anxiety (SA) were evaluated by GSE Scale, Trait Coping Style Questionnaire and SA Scale, respectively. Bayesian network was applied to evaluate the relationship between psychological factors and successful smoking cessation. The local conditional probability table of smoking cessation indicated that different joint conditions of psychological factors led to different outcomes for smoking cessation. Among smokers with high PTCS, high NTCS and low SA, only 36.40% successfully quitted smoking. However, among smokers with low pack-years of smoking, high GSE, high PTCS and high SA, 63.64% successfully quitted smoking. Our study indicates psychological factors jointly influence smoking cessation outcome. According to different joint situations, different solutions should be developed to control tobacco in practical intervention.

Comparison of conventional medicine, TCM treatment, and combination of both conventional medicine and TCM treatment for patients with chronic obstructive pulmonary disease: study protocol of a randomized comparative effectiveness research trial.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) affects millions worldwide. Although many therapies exist and are being developed to relieve symptoms and reduce mortality, few data are available to understand which of the therapeutic alternatives is the most cost-effective for COPD patients in everyday clinical practice, especially for traditional Chinese medicine (TCM). Comparative effectiveness research can help patients, clinicians, and decision-makers make best informed treatment decisions where such evidence was previously lacking. This study aims to compare the effectiveness and economic evaluation of three treatments: (1) conventional Western medicine; (2) TCM treatments, which have been evaluated and have certain effect; and (3) a combination of both conventional Western medicine and TCM treatments, and then determine which treatment is the most suitable for COPD patients. METHODS/DESIGN: A multicenter, pragmatic, randomized, controlled trial is adopted. A total of 360 patients will be recruited and randomly assigned to one of the three treatments group, with 120 in each group. Patients in the conventional Western medicine group will be given Salbutamol, Formoterol, Salmeterol/fluticasone, respectively, according to the guidelines. For the TCM group, patients will be given Bufei granule, Bu-Fei Jian-Pi granule, Bu-Fei Yi-Shen granule, and Yi-Qi Zi-Shen granule based on their corresponding TCM syndrome patterns, respectively. For the combination of conventional medicine and TCM treatments group, patients will be given a combination of conventional Western medicine and TCM granules. Treatments in each group are recognized as a whole comprehensive intervention. After the 26-week treatment, another 26 weeks will be followed up. The outcome measures including the frequency and duration of acute exacerbations, lung function, dyspnea, exercise capacity, quality of life, and economic evaluation will be assessed. DISCUSSION: It is hypothesized that each of the three treatments will have beneficial effects in reducing the frequency and duration of acute exacerbations, improving exercise capacity and psychosocial function of COPD patients. In addition, the combination of conventional medicine and TCM treatments may be most suitable for COPD patients with better effectiveness and economic evaluation.
