BACKGROUND:Researches about sub-health status in general community population are rare,especially in minor nationalities.OBJECTIVE:To explore the sub-health status and its risk factors with logistic regression model and negative binomial regression model in Tibetan people.DESIGN,TIME AND SETTING:A cross-sectional study was performed among subjects selected from Songpan county in the Aba Tibetan and Qiang Autonomous Prefecture of Sichuan Province on September 2007.PARTICIPANTS:A total of 1791 Tibetan subjects from were recruited from Songpan county in the Aba Tibetan and Qiang Autonomous Prefecture of Sichuan Province and were involved in this study,among which 1763 subjects completed the sub-health questionnaire.Their average age was 27 years,ranging from 10 to 80.There were 731 male subjects (41.5%)and 1032 female ones (58.5%).All subjects were informed of the survey regimen.METHODS:The sub-health rating scale framed by Chen Qingshan et al was used to assess the sub-health status of subjects with stratified and cluster sampling,including the prevalence rate of sub-health status,the number of sub-health symptoms and various dimensional prevalence.MAIN OUTCOME MEASURES:Risk factors of sub-health status with logistic regression model and negative binomial regression model.RESULTS:There were 1038 subjects suffering from one or more sub-health symptoms,and they were considered as being in the sub-health status with the prevalence of sub-health 58.9%.The split-half reliability and internal consistency of the scale were separately 0.7658 and 0.8154.Logistic regression results indicated that the seniors (P=0.0004),female (P＜0.0001),marriage status (P=0.0008),mental labor (P=0.0021)and smoking (P＜0.0001)were main contributing factors of sub-health status.However,marriage status (P=0.0689)and occupation (P=0.1398)weren't statistically significant in negative binomial regression analyses.CONCLUSION:Tibetan populations living in high altitude are also suffering from sub-health status and should be given more attention.Further more negative binomial regression model could be popularized to analyze sub-health and its influencing factors.

A rapid, sensitive and simple liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed for the simultaneous determination of yogliptin and its metabolite in Wistar rat plasma. Linagliptin and dexamethasone were chosen as the internal standards of yogliptin and its metabolite, (R)-8-(3-hydroxypiperidine- -yl)-7-(but-2-yn-1-yl)-1-((5-fluorobenzo[d]thiazol-2-yl)methyl)-3-methyl- H-purine-2, 6 (3H, 7H)-dione, respectively. After a simple protein precipitation using acetonitrile as the precipitating solvent, both analytes and ISs were separated on a Grace Altima HP C18 column (2.1 mm x 50 mm, 5 microm) with gradient elution using methanol (containing 0.1% formic acid, 4 mmol x L(-1) ammonium acetate)-0.1% formic acid (containing 4 mmol x L(-1) ammonium acetate) as the mobile phase. A chromatographic total run time of 4.4 min was achieved. Mass spectrometric detection was conducted with electrospray ionization under positive-ion and multiple-reaction monitoring modes. Linear calibration curves for yogliptin and its metabolite were over the concentration range of 0.5 to 500 ng x mL(-1) with a lower limit of quantification of 0.5 ng x mL(-1). The intra- and inter- assay precisions were all below 14%, the accuracies were all in standard ranges. The method was used to determine the concentration of yogliptin and M1 in Wistar rat plasma after a single oral administration of yogliptin (27 mg x kg(-1)). The method was proved to be selective, sensitive and suitable for pharmacokinetic study of yogliptin and M1 in Wistar rat plasma.

The drug poisoning is the most common cause of children′s accident.The percentage is increasing every year. Analgesics,non-steroidal anti-inflammatory drugs and antihistamines are the most commonly ingested drugs in children.The principles of management of drug poisoning are:(1)resuscitation and initial stabilization; (2)diagnosis of type of poision.According to recent studies,gastric lavage should not routinely be used in all poisoning cases,instead the use of activated carbon is recommended.For severe or special cases advanced life support technologies such as mechanical ventilation,blood purification,extracorpo-real membrane oxygenation should be considered.

Objective: To describe the baseline characteristics of School-based Cardiovascular and Bone Health Promotion Program(SCVBH) in Beijing. Methods: Children and adolescents were selected in 30 schools (8 primary schools, 21 middle schools and one 12-year education school) from Dongcheng, Tongzhou, Fangshan and Miyun districts of Beijing by using a stratified cluster sampling method. 15 391 students in grade 1 to 4 from primary schools, grade 1 from junior and senior high schools were enrolled in the investigation with an exclusion of students who were not able to participate due to trauma or other uncomfortable physical conditions. The baseline survey including a questionnaire survey, physical examination and blood biochemical test was conducted from September 2017 to January 2018. Obesity, blood pressure, fasting blood glucose, lipid, bone density and grip were evaluated. Results: The prevalence of obesity, hypertension, hyperglycemia (impaired fasting glucose and diabetes), dyslipidemia, lower bone density were 22.3%(3 394), 14.8%(2 248), 10.4%(1 490), 20.3%(2 919) and 2.1%(316) in total respectively, and 27.2%(2 081), 16.3%(1 244), 12.8%(922), 22.2%(1 595) and 1.2%(94) for boys, 17.3%(1 313), 13.3% (1 004), 7.9%(568), 18.4%(1 324) and 2.9%(229) for girls. Boys had higher prevalence of obesity, hypertension, hyperglycemia, and dyslipidemia and lower prevalence of low bone density than girls (all P values <0.05) The mean of body mass index, systolic blood pressure, fasting plasma glucose and grip of boys were significantly higher than that of girls (all P values <0.05).The mean of body mass index, systolic blood pressure, fasting plasma glucose and grip of boys were significantly higher than that of girls (all P values <0.05), the mean of fat mass percentage, total cholesterol, triglyceride, high density lipoprotein-cholesterol and low density lipoprotein-cholesterol of boys were significantly lower than those of girls (all P values <0.05). Conclusion The prevalence of risk factors of chronic cardiovascular disease was high and the low bone density was appearing in children and adolescents in this study. The promotion of cardiovascular and bone health should be implemented in children and adolescents.

Objective To explore the influences of situation-background-assessment-recommendation communication mode for caring behavior and caring load of hemodialysis patients home caregivers. Methods A total of 216 caregivers who took care of hemodialysis patients were selected in our hospital for treatment and were averagely divided into observation group ( implement personalized education plan for nursing education ) and control group ( implement routine nursing education) . We compared caring behavior and caring load between two groups by LC-GADs and caregiver′s pressure load scale. Results The 5 abstract behavior dimensions in patients of observation group including endorsement, evaluation, guidance, form a regular, keep balance were (3. 25 ± 0. 52), (3. 58 ± 0. 41), (3. 49 ± 0. 50), (3. 21 ± 0. 71), (3. 45 ± 0. 48) which were higher than those of the control group, the differences were statistically significant ( t = -7. 364, -4. 011, -9. 025, -4. 254,-3. 896;P<0. 01); the specific behavior scores in observation group were significantly higher than that of control group as well (P <0. 01). In the observation group, emotions and economic stress, the body and personal time pressure, psychological pressure and family relationship were (1. 82 ± 0. 35), (1. 93 ± 0. 35), (1.85 ±0.54) and (1. 68 ± 0. 45) which were lower than those of the control group (t =4. 365, 3. 563, 3. 657, 4. 615; P <0. 01). Conclusions Caregivers of hemodialysis patients receive situation-background-assessment-recommendation communication mode which can obviously improve caregivers caring behavior, reduce caregivers caring load, and improve the quality of care.

OBJECTIVEFindings from the previous studies have suggested a relationship between ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP-1) or plasma cell membrane glycoprotein 1 (PC-1) gene single nucleotide polymorphism (K121Q, rs1044498) and genetic susceptibility to obesity. However, such relationship is not reproduced by some currently available studies. In this context, the present study is aimed to quantitatively analyze the association of K121Q variant with obesity in all published case-control studies in European adult populations.

METHODSPublished literature from PubMed, EMBASE, and ISI web of science databases were retrieved. The studies evaluating the association of ENPP1/PC1 gene K121Q polymorphism with obesity were included, in which sufficient data were presented to calculate the odds ratio (OR) with 95% confidence intervals (CIs).

RESULTSTen case-control studies meeting the inclusion criteria identified a total of 24,324 subjects including 11,372 obese and 12,952 control subjects. The meta-analysis results showed a statistically significant association of K121Q with obesity [OR (95%CI): 1.25 (1.04-1.52) P=0.021] under a recessive model of inheritance (QQ vs. KK+KQ) without heterogeneity or publication bias.

CONCLUSIONSThe results from the present study have indicated that ENPP1/PC1 Q121 variant may increase the risk of obesity and that more well-designed studies based on a larger population will be required to further evaluate the role of ENPP1/PC1 gene K121Q polymorphism in obesity and other related metabolic syndromes.

Objective To understand the association between body fat distribution and calcaneal bone mineral density (BMD) in children and adolescents aged 6-16 years in Beijing. Methods Children and adolescents were selected in 30 schools (8 primary schools, 21 middle schools and one 12?year education school) from Dongcheng, Tongzhou, Fangshan and Miyun districts of Beijing by using a stratified cluster sampling method from November 2017 to January 2018. A total of 15 030 students in grade 1 to 4 of primary school, grade 1 of junior and senior middle school were enrolled after excluding subjects who were not able to participate into this study due to trauma or other uncomfortable physical conditions or with missing key values or with diabetes and kidney diseases. Questionnaire survey, body composition and calcaneus bone mineral density were conducted. The relation of fat mass percentage (FMP), trunk to total fat ratio (TrTFR), trunk to limb fat ratio (TrLFR), limb to total fat ratio (LTFR) and viscera to total fat ratio (VTFR) with calcaneus BMD were assessed using the multivariate linear regression models after adjusting for possible confounding effects. The central fat distribution types were divided into 4 groups including type 1: both trunk fat and visceral fat greater than the sex?and age?specific internal P75; type 2: barely trunk fat greater than P75; type 3: barely visceral fat greater than P75; type 4: both trunk fat and visceral fat greater than P75. The central fat distribution types were included into the model in the form of dummy variables to analyze its relationship with calcaneal BMD. The sex?and age?specific z?scores of fat distribution indicators and BMD were calculated. Results A total of 15 030 participants aged (11.4 ± 3.3) years (50.2% boys) were involved in the analysis. In both genders, after adjusting for age, height, lean mass index, smoking, drinking, physical activity, milk intake, vitamin D and calcium supplementation, FMP, TrTFR, TrLFR and VTFR were negatively correlated with calcaneal BMD (all P value<0.05), while LTFR was positively associated with calcaneal BMD (all P values<0.05). Compared to the central fat distribution type 1, the regression coefficients (95% CI ) of type 2, 3 and 4 were-0.253 (-0.418,-0.087),-0.385 (-0.567,-0.204) and-0.428 (-0.487, -0.369) in boys, respectively; the regression coefficients (95% CI) of type 3 and 4 were -0.158 (-0.301,-0.015) and-0.226 (-0.290,-0.163), respectively. Conclusion Body fat distribution and central fat distribution in children and adolescents were correlated with calcaneus bone mineral density.

Objective To investigate the association between blood lipid and calcaneus bone mineral density (BMD) in children and adolescents aged 6-16 years in Beijing. Methods Children and adolescents were selected in 30 schools (8 primary schools, 21 middle schools and one 12?year education school) from Dongcheng, Tongzhou, Fangshan and Miyun districts of Beijing by using a stratified cluster sampling method from November 2017 to January 2018. A total of 14 303 students in grade 1 to 4 of primary school, grade 1 of junior and senior middle school were enrolled after excluding subjects who were not able to participate into this study due to trauma or other uncomfortable physical conditions or with missing key values or with diabetes and kidney diseases. Questionnaire survey, blood lipid and calcaneus BMD were conducted. Multivariate linear regression was applied to quantify the association between calcaneal BMD as a dependent variable and blood lipid level as an independent variable after adjusting for the potential confounding factors. Furthermore, quantile regression was used to analyze the association between blood lipid level and different percentiles (P25, P50 and P75) of ultrasonic velocity values of bone mineral density, and parallel test was conducted for regression coefficients of different percentiles. Results A total of 14 303 participants aged (11.4 ± 3.3) years (49.9% boys) were involved in the analysis. The mean age of 14 303 participants was (11.0±3.3) years. 7 142 boys accounted for 49.9%. The mean±SD of calcaneal BMD, total cholesterol (TC), low density lipoprotein?cholesterol (LDL?C), and high density lipoprotein?cholesterol (HDL?C) were (1 540.9±33.8) m/s, (3.90±0.76), (2.18±0.62), and (1.40±0.32) mmol/L, respectively. The P50 (P25, P75) of triglyceride (TG) was 0.69 (0.49-0.94) mmol/L. After the adjustment of age, height, smoking, drinking, vitamin D and calcium supplementation, dairy intake, physical activity, FMI, and MMI, a significantly inverse association (P<0.05) between TG level and calcaneus BMD was observed in both genders, which the regression coefficients (95%CI ) in boys and girls were -0.064 (-0.085,-0.044) and-0.073 (-0.094,-0.053), respectively. Conclusion The level of BMD was associated with TG in boys and girls. Therefore, it is important to prevent children from hypertriglyceridemia for the bone health promotion.
