OBJECTIVETo perform a comparative analysis of the reactivation rate of hepatitis B virus (HBV) infection and related risk factors after treatment of HBV-related hepatocellular carcinoma (HCC) by radiofrequency ablation (RFA) or hepatic resection.

METHODSWe retrospectively analyzed the HBV reactivation rate and related risk factors of a cohort of 218 patients treated for HBV-related HCC between August 2008 and August 2011; the study population consisted of 125 patients who received RFA and 93 patients who received hepatic resection. Comparisons were made using the unpaired Student's t-test for continuous variables and the x2-test and Fisher's exact test for categorical variables. Univariate and multivariate logistic regression analysis was used to assess risk factors.

RESULTSTwenty patients showed HBV reactivation following treatment, but the incidence was significantly lower in the RFA group than in the hepatic resection group (5.6% vs. 14.0%, 7/125 vs. 13/93, x2 = 4.492, P = 0.034). The univariate and multivariate analysis indicated that no antiviral therapy (OR = 11.7; 95% CI: 1.52-90.8, P = 0.018) and the treatment type (i.e. RFA or hepatic resection) (OR = 3.36; 95% CI: 1.26-8.97, P = 0.016) were significant risk factors of HBV reactivation. Subgroup analysis showed that the incidence of HBV reactivation was lower in patients who received antiviral therapy than in those who did not for both the RFA group and the hepatic resection group but the difference was not significant in the former group (1/68 vs. 19/150, x2=7.039, P = 0.008 and 0/33 vs. 7/92, x2 = 2.660, P = 0.188, respectively). However, the incidence of HBV reactivation in patients who did not receive antiviral therapy was higher than in those who did receive antiviral therapy in the hepatic resection group (12/58 vs. 1/35, x2 = 5.773, P = 0.027).

CONCLUSIONThe incidence of HBV reactivation was lower in patients who received RFA than in those who received hepatic resection to treat HBV-related HCC. Antiviral therapy prior to the hepatic resection treatment may be beneficial for reducing the incidence of HBV reactivation.

OBJECTIVETo examine the prevalence of obesity phenotypes and cardiometablic disorders (CDs) among children aged 6- 17 in Beijing from 2004 to 2013.

METHODSData were obtained from two cross-section surveys, which were conducted in 2004 and 2013. In 2004, by using stratified cluster sampling design, 20 primary or middle schools were selected from 7 districts (Xicheng, Dongcheng, Chaoyang, Haidian, Daxing, Pinggu, and Yanqing) in Beijing, and 20 554 school children aged 6-17 were recruited, with weight, height, waist circumference and blood pressure measured. Fasting plasma glucose (FPG), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) were measured in 962 subjects from one school. In 2013, by using the same sampling design, 7 211 students from two districts (Haidian and Dongcheng) were surveyed with weight, height, waist circumference and blood pressure measured, and fasting plasma glucose and lipid profile (TC, TG, HDL-C, LDL-C) were measured for 1 344 subjects in the same school measured in 2004. Student's-t test was used to analyze the difference in body mass index(BMI), WC, and waist to height ratio (WHtR) among children between 2004 and 2010. Chi-square test was used to analyze the difference of hypertension, impaired fasting glucose(IFG), dyslipidemia, and metabolic disorders clustering between 2004 and 2010, and among different types of obesity; logistic regression model was used to analyze the association between three types of obesity and risks of cardiovascular metabolic disorders.

RESULTSIn boys, BMI ((20.3 ± 4.4) vs (19.4 ± 4.2) kg/m(2), t=11.18, P<0.001), WC ((70.6 ± 12.8) vs (66.7 ± 11.8) cm, t=17.20, P<0.001) and WHtR (0.451 ± 0.064 vs 0.437 ± 0.059, t=11.64, P<0.001) were significantly higher in 2013 than those in 2004. Similarly in girls, BMI ((18.9 ± 3.6) vs (18.7 ± 3.7) kg/m(2), t=12.21, P<0.001), WC ((64.5 ± 9.6) vs (63.0 ± 9.3) cm, t=8.15, P<0.001) and WHtR (0.430 ± 0.047 vs 0.423 ± 0.047, t=14.13, P<0.001) were also significantly higher in 2013 than those in 2004. The prevalence of combined obesity rose from 8.27% (1 697/20 526) in 2004 to 10.74% (774/7 209) in 2013, and central obesity from 3.08% (632/20 526) to 4.44% (320/7 209). The prevalence of hypertension (10.78%(313/1 344) vs 4.29% (42/962), χ(2)=36.76, P<0.001), IFG(49.54%(664/1 344) vs 6.45%(63/962), χ(2)=506.61, P<0.001), high TC(11.53%(155/1 344) vs 5.03%(49/962), χ(2)=28.31, P< 0.001), high TG(7.51%(101/1 344) vs 3.59%(35/962), χ(2)=29.59, P<0.001) were significantly higher in 2013 than those in 2004. Subjects with combined obesity had higher risks of hypertension (OR=5.88, 95% CI: 4.42-7.82), high TG (OR=7.12, 95%CI: 4.35-11.64), low HDL-C (OR=3.04, 95%CI: 1.55-5.95), high LDL-C (OR=2.27, 95% CI: 1.22-4.02), CDs≥2 (OR=3.07, 95% CI: 2.09-4.50), comparing to children without obesity.

CONCLUSIONThe prevalence of types of obesity and obesity-related metabolic disorders, except for low HDL-C and high HDL-C, were significantly higher in 2013 than those 2004 among chlildren aged 6-17 year in Beijing. Children with combined obesity had higher prevalence of metabolic disorders.

Objective To understand the current status of physical activity among urban school-aged children and its association with obesity.Methods 295 pupils,aged 9 to 13 years were selected,using the method of convenience sampling.Data on anthropometric measurements was collected,including weight and height.Questionnaire survey,clinic examination,dietary investigation of school lunch and surveillance on 7-day physical activity by pedometers,were done and Multi-linear regression was used to analyze the relationship between waist to height ratio (WHtR),fat mass percentage (FMP),body mass index (BMI) and physical activity.Single-variable and multiple non-conditional logistic regression modeling were applied to analyze data collected from obesity and physical activities.Results 15.5％ of boys and 13.1％ of girls reached 60 minutes per day of ‘ moderate-vigorous physical activities’.Compared with normal children,overweight/obesity children showed an increase of sedentary activity time,total energy expenditure,and energy expenditure of physical activity.With the increase of 1 hours daily on going to school by private car,WHtR and FMP increased by 0.01 and 2.06 units,respectively.FMP increased 0.89 units among with the increase of sedentary activity time,1 hour daily.BMI and the intake of leafy vegetables (eg.spinach,cabbage)showed a negative correlation.As the frequency of leafy vegetables consumption increased once weekly,BMI fell 0.10 units.After adjustment for sex and age,the risk of overweight/obesity was 3.82-fold (95％CI:1.17-12.47) among children who had sedentary activity time more than 120 min/ d,than those having less than 120 min/d.Conclusion Our data showed that children' s daily physical activity was not enough and measures should be taken to decrease the time of sedentary behavior and increase the energy expenditure through physical activities.

Objective: To explore the relationship between prepregnancy body mass index, weight gain during pregnancy with preschool obesity and body composition in offspring, so as to provide evidence for gestational weight gain and childhood obesity prevention. Methods: A total of 1 333 preschool children were recruited from 3 kindergartens in Tianjin from September to December 2020. Structured questionnaire was used to collect children s lifestyle information. Height, weight and body fat mass of children were assessed, and body fat percentage (FM%), fat mass index (FMI) and non fat mass index (FFMI) were calculated. Maternal medical records were collected and the mothers were grouped according to their prepregnancy weight status and weight gain during pregnancy. χ 2 test, t test, linear regression model and Logistic regression were used to analyze the differences of obesity and body composition among different groups. Results: The prevalence of overweight and obesity in preschoolers was 12.7% and 7.7%. After adjusting maternal age and delivery, gestational age, gender, age and lifestyle of children, the correlation between maternal pre pregnancy BMI,gestational weight gain with obesity and body composition indexes of children in preschool age was statistically significant ( P <0.05). For mothers with normal weight before pregnancy, excessive weight gain during pregnancy increased risk of high FM% and high FMI in offspring ( OR=1.81, 1.68, P <0.05). There was no significant correlation between maternal weight gain during pregnancy with offspring obesity and body composition among mothers with prepregnant overweight or obesity. Conclusion Maternal weight status before pregnancy and weight gain during pregnancy are correlated with obesity and body composition in the preschool age of offspring. It is suggested that mothers should maintain appropriate weight status before and during pregnancy.

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 effects of exercise-psychology-sleep nursing among esophageal cancer patients. Methods? From June 2016 to September 2018, we selected 200 esophageal cancer inpatients with intermediate and advanced stage in Surgery Department at the First Affiliated Hospital of Xi'an Jiaotong University by convenience sampling. All of the patients were divided into control group and experimental group according to admission order, 100 cases in each group. Control group carried out routine nursing. On the basis of routine nursing, experimental group implemented exercise-psychology-sleep nursing. After intervention, the intervention effects were compared with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Revised Piper Fatigue Scale (PFS-R) between two groups. Results? One month after intervention, the scores of function and general health of experimental group were (62.11±3.22) and (67.23±3.74) respectively higher than those of control group; the scores of symptoms and specificity of experimental group were (42.12±2.13) and (43.75±3.21) respectively lower than those of control group; the differences were all statistical (t=101.159,15.053,22.910,3.347;P＜0.01). The scores of cancer related fatigue of experimental group and control group were (3.36±1.25) and (5.14±1.04) respectively with a statistical difference (t=10.663,P＜0.01). Conclusions The application of exercise-psychology-sleep nursing in esophageal cancer patients can improve quality of life and relieve cancer related fatigue of patients which is worthy of being widely used in clinical application.

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.

Extremity compartment syndrome can cause neuromuscular ischemia and deposition of metabolites in the compartment,leading to irreversible lesions which harm limb functions in the end.It is a great challenge for surgeons to make a timely and accurate diagnosis of the syndrome in adults and children.The key is evaluation of the clinical symptoms and intracompartmental pressure.In this paper we summarize the epidemiology,etiology,pathophysiology,and current diagnosis and treatment of acute extremity compartment syndrome of the upper and lower extremities in adults and children.

Objective To investigate the expression and significance of microtubule-associated protein 1 light chain 3 (LC3), an autophagy marker protein, in ameloblastomas. Methods Immunohistochemical methods were employed to evaluate the expression of LC3 in104 cases of ameloblastomas and 20 cases of normal oral mucosal tissues. The results were analyzed by a semiquantitative analysis method. Results The reactivity of LC3 in the epithelial cells of ameloblastomas was positive, and the positivity rate was significantly higher than that in normal oral mucosal tissues (P ＜ 0.05). There were no significant differences between the LC3 expression levels with respect to age, gender, or recurrence (P ＜ 0.05). The positivity rate in mandible ameloblastomas was significantly higher than that in maxilla and gingiva ameloblastomas (P ＜ 0.05). The reactivity for LC3 was significantly higher in solid ameloblastomas than that in the other three tissue types (P ＜ 0.05). Conclusion Autophagic activity in ameloblastomas was higher than that in normal oral mucosal tissues. This suggests that autophagy plays an important role during tumorigenesis, and contributes to the local invasion of ameloblastomas.
