ABSTRACT
ObjectiveTo examine the current status of preschoolers' eating behaviors and investigate its correlation with family cohesion and adaptability. MethodsA cross-sectional study was conducted involving 21，954 preschoolers and their families from Pingshan District， Shenzhen， between September 2021 and December 2021. A general demographic questionnaire， the Chinese version of Family Adaptability and Cohesion Evaluation Scale Ⅱ （FACESⅡ-CV） and Chinese Preschoolers’ Eating Behavior Questionnaire （CPEBQ） were used to collect the relevant information. Multiple linear regression was used to analyze the association of family cohesion and adaptability with eating behaviors of preschoolers. ResultsTypes of family cohesion and adaptability were significantly correlated with all the 7 dimensions of preschoolers' eating behaviors， including food fussiness （R2=0.252， F=114.457， P<0.001）， food responsiveness （R2 = 0.111， F =24.973， P<0.001）， eating habit （R2= 0.304， F =139.658， P<0.001）， satiety responsiveness （R2 = 0.259， F =105.332， P<0.001）， external eating （R2 = 0.182， F =50.150， P<0.001）， emotional eating （R2 = 0.234， F =91.084， P<0.001） and initiative eating （R2 = 0.349， F =168.608， P<0.001）. After adjusting for confounding factors， our study showed that types of family cohesion and adaptability were independent predictors of preschoolers' eating behaviors （P<0.05）. ConclusionsTypes of family cohesion and adaptability have a significant predictive effect on the 7 dimensions of preschoolers' eating behaviors. Higher scores of family cohesion and adaptability imply stronger initiative eating ability and less poor dietary behaviors in preschoolers.

ABSTRACT
Biosimilars are biological medicinal products that are highly similar to an already licensed reference product in terms of quality, safety, and efficacy. BAT1706 is being developed by Bio-Thera Solutions, Ltd. as a proposed biosimilar candidate to bevacizumab reference product (Avastin®). Bevacizumab acts by specifically binding to vascular endothelial growth factor A (VEGF-A), and preventing the interaction of VEGF-A with its receptors on the surface of endothelial cells, then blocking the downstream signaling pathway mediated by ligand-receptor, and inhibiting endothelial angiogenesis, thus inhibiting tumor growth. Comprehensive analytical characterization studies incorporating orthogonal analytical techniques were performed to compare the in vitro functional activities of BAT1706 and Avastin®. BAT1706 and Avastin® showed highly similar binding activity to multiple VEGF-A isoforms and equivalent VEGF-A neutralizing activity, as well as inhibitory activity of VEGF receptor (VEGFR)-2 tyrosine kinase autophosphorylation. Both products exhibited similar binding of the Fcγ receptors and a lack of Fc-related effector functions such as antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Overall, the results demonstrate that BAT1706 and Avastin® are highly similar in terms of in vitro functional activities.

ABSTRACT
Objective@#To estimate the incidence and mortality of bladder cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR).@*Methods@#There were 449 cancer registries submitted bladder cancer new cases and deaths occurred in 2014 to NCCR. After evaluating the data quality, 339 registries′ data were finally accepted for analysis. According to the national population data of 2014, the nationwide incidence and mortality of bladder cancer were estimated by stratification in the area (urban or rural), gender, and age. Chinese population census in 2000 and Segi′s population were used for age-standardized incidence/mortality rates.@*Results@#All 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas). The percentage of morphologically verified cases and death certificate-only cases were 74.86% and 1.45%, respectively. The mortality to incidence ratio was 0.41. The estimates of new bladder cancer cases were 78 100 in China in 2014, with a crude incidence rate of 5.71/100 000. The age-standardized incidence rates by China standard population (ASR China) and world standard population (ASR world) of bladder cancer were 3.61/100 000 and 3.56/100 000, respectively. Cumulative incidence rate of bladder cancer in China was 0.41%. The crude and ASR China incidence rates in urban areas were 6.88/100 000 and 4.07/100 000, respectively, whereas those were 4.29/100, 000 and 2.96/100 000 in rural areas. The estimates of bladder cancer deaths caused by bladder cancer were about 32 100 in China in 2014, with a crude mortality rate of 2.35/100 000. The ASR China and ASR world mortality rates were both 1.30/100 000 with a cumulative mortality rate (0-74 years old) of 0.12%. The crude and ASR China mortality rates were 2.79/100 000 and 1.41/100 000 in urban areas, respectively, whereas those were 1.81/100 000 and 1.14/100 000 in rural areas.@*Conclusions@#The incidence and mortality pattern of bladder cancer were different in urban and rural areas. The incidence and mortality were higher in urban areas than that in rural areas, and higher for male than for female. We should focus on strengthening the prevention and control of bladder cancer in key population, especially men in urban areas.
ABSTRACT
Lung cancer is one of the most important malignant tumors in the world. The morbidity and mortality rank the first in all kinds of cancer. Long non-coding RNA (lncRNA) is at least 200 nt long and has no protein coding capacity. It plays an important role in the epigenetic regulation, cell cycle regulation, the regulation of cell differentiation, and many other life activities. The studies indicate that dysregulation of lncRNAs in non-small cell lung cancer (NSCLC) tissue and blood circulation is associated with the occurrence and development of cancer. The lncRNAs play an significant role in proliferation, differentiation, migration and apoptosis of the tumor cells. Explore the potential mechanism between lncRNAs and NSCLC is beneficial for the early diagnosis, target therpy and improve prognosis. Therefore, the study aims to demonstrate the latest studies on the lncRNAs related to occurence, diagnosis, therpy and prognosis of NSCLC. It can help to deeply understanding of lncRNA, and provide new ideas for the prevention of NSCLC.

ABSTRACT
Objective@#The National Central Cancer Registry (NCCR) collected esophageal data of local cancer registries in 2013 to estimate the incidence and mortality in China.@*Methods@#Data submitted from 347 registries were evaluated and 255 registries' data are qualified by NCCR. Data of incidence and mortality were stratified with areas (urban/rural), gender and age group. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality.@*Results@#All of 255 cancer registries covered a total of 226 494 490 population (111 595 772 in urban areas and 114 898 718 in rural areas). The morphology verified cases (MV%) of esophageal cancer accounted for 75.51% and 1.64% of incident cases were identified through death certifications only (DCO%) with mortality to incidence ratio of 0.75. The estimates of new esophageal cancer cases and deaths were 277 thousand and 206 thousand in China, respectively. The crude incidence rate of esophageal cancer in Chinese cancer registration areas was 20.35/105 (28.15/105 in male, 12.15/105 in female), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population were 13.64/105 and 13.82/105 with the cumulative incidence rate (0-74 age years old) of 1.77%. The esophageal cancer incidence and ASIRC were 13.38/105 and 8.74/105 in urban areas whereas in rural areas, they were 28.44/105 and 19.56/105, respectively. In rural areas, the crude incidence rate of esophageal cancer was 2.13 times higher than that in urban areas, and after age-standardized it remained 2.24 times higher. The esophageal cancer mortality in Chinese cancer registration areas was 15.17/105 (20.86/105 in male and 9.20/105 in female), age-standardized mortality by Chinese standard population (ASMRC) and by world standard population were 9.95/105 and 9.98/105, with the cumulative mortality rate (0-74 age years old) of 1.20%. The esophageal cancer mortality and ASMRC were 10.12/105 and 6.46/105 in urban areas, whereas in rural areas, they were 21.05/105 and 14.16/105, respectively. In rural areas, the esophageal cancer mortality and ASMRC were 2.08 and 2.19 times higher than those in urban areas. Esophageal cancer was the sixth common cancer and the fourth leading causes of cancer death, accounting for about 7.52% of all cancer cases and 9.26% of all cancer deaths.@*Conclusions@#Esophageal cancer is one of the most common cancers in China. Screening and early detection are important to reduce the incidence and mortality.
ABSTRACT
Background and purpose: Colorectal cancer is one of the most common gastrointestinal cancers. There were about 1.36 million new cases of colorectal cancer, which was the third highest incidence of malignant tu-mors of the world in 2012. It was the fourth leading cause of cancer death and became a serious threat to human health. The aim of the study was to estimate the colorectal cancer burden in Hebei Province with the data of cancer registries areas and analyze the trend of colorectal cancer mortality rates with three of the Hebei Province death retrospective surveys. Methods: Nine cancer registries in Hebei Province submitted cancer registry data from 2010 to 2012 to the Hebei Provincial Cancer Registry Center. The pooled data were stratified by gender and age (0, 1-4, 5-9, 10-14…80+). Proportions and incidence/mortality rates for colorectal cancer were calculated. Incidence and mortality rates were age-standardized to Chinese population census in 2000 and world Segi's population standard. Colorectal cancer mortal-ity data during the periods 1973-1975, 1990-1992 and 2004-2005 were extracted from the death retrospective surveys and analyzed. Mortality and incidence rate data from Cixian County from 1988 to 2012 and Shexian County from 2000 to 2012 were obtained in each county and analyzed using Joinpoint regression model. Results: The estimated number of newly diagnosed colorectal cancer cases and deaths from 2010 to 2012 in cancer registry areas of Hebei Provinc were 2303 and 1229, respectively. The crude incidence rate of colorectal cancer was 16.48/100000 (male 18.12/100000 and female 14.77/100000). The age-standardized incidence rate by Chinese population census (ASRC) in 2000 was 13.74/100000. The colorectal cancer mortality rate was 8.79/100000 (male 10.23/100000 and female 7.31/100000). The age-standardized mortality rate by Chinese population census (ASRC) in 2000 was 7.59/100000. The mortality rates of colorectal cancer displayed a significant increasing trend in Hebei Province from 1973-1975 to 2010-2012, with an increased rate of 28.03%. In Cixian County, the annual percentage change (APC) of colorectal cancer incidence rate was 3.55, while the APC of colorectal cancer mortality rate was 1.64 for males from 1988 to 2012. In Shexian County, the APC of colorectal cancer incidence rates were 4.68 and 9.17 for males and females from 2000 to 2012, respectively;the APC of colorectal cancer mortality was 5.61 for males in Shexian County. Conclusion: The incidence and mortality rates of colorectal cancer showed an increasing trend in Hebei Province over the past 40 years. It is an important task that colorectal cancer screening is strengthened to reduce morbidity and mortality of the colorectal cancer in Hebei Province.

ABSTRACT
<p><b>OBJECTIVE</b>To explore the prognostic value of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in patients with gastric cancer.</p><p><b>METHODS</b>591 cases of gastric cancer pathologically diagnosed at the Fourth Hospital of Hebei Medical University in 2006 were included in this study. The clinical information including age and gender, cancer, treatment, and the first blood test information at admission were collected from the medical record room and analyzed. The patients were followed up to March 15, 2012. The survival was calculated by Kaplan-Meier analysis. The differences between groups were compared using Log-rank test. Cox regression was used to analyze the factors which may affect the survival of the patients. Software SPSS 13.0 was used for statistical analysis.</p><p><b>RESULTS</b>In 2006, a total of 591 patients were enrolled in this study in accordance with the inclusion criteria. By the end of the study, 538 cases were followed up. The follow-up rate was 91.0%. Among them 353 cases died of gastric cancer, 185 patients are still alive. In the whole group of 538 cases, the 1-, 3-, and 5-year survival rate was 69.9%, 47.0%, and 37.5%, respectively. In the low NLR group, the 1-, 3-, and 5-year survival rate was 76.1%, 50.1%, and 42.7%, respectively, while those of the high NLR group was 53.1%, 38.6%, and 23.4%, respectively, showing a significant difference between the two groups (P < 0.05). Univariate analysis showed that the survival rate was significantly correlated with age, pathological type, TNM stage, operation, NLR and PLR (P < 0.05 for all). Multivariate analysis showed that TNM stage, operation, NLR and age of patients were independent risk factors for the prognosis of gastric cancer (P < 0.05 for all). According to the sub-site stratified analysis, TNM stage, operation and NLR were independent risk factors for gastric cardia adenocarcinoma (P < 0.05 for all), and age, TNM stage, operation for distal gastric cancer (P < 0.05 for all). PLR was not an independent prognostic factor of survival in patients with gastric cancer.</p><p><b>CONCLUSION</b>NLR may be an independent prognostic factor of gastric cancer.</p>

<p><b>OBJECTIVE</b>To observe the effect of Shuanghuanglian injection on cerebral expression of nuclear factor-kappaB (NF-kappaB) in mice with viral encephalitis.</p><p><b>METHODS</b>The mice with experimental viral encephalitis received treatment with Shuanghuanglian injection at the dose of 0.2, 1.5, and 5 for 5, 10 or 20 consecutive days. The total RNA of the brain tissue was extracted to analyze the protein and mRNA expression of NF-kappaB using Western blotting and RT-PCR, respectively.</p><p><b>RESULTS</b>Compared with the control group, the mice with experimental viral encephalitis showed significantly increased protein and mRNA expressions of NF-kappaB (P<0.01). Treatment with Shuanghuanglian injection at the doses of 0.2 and 1.5 mg/kg significantly lowered NF-kappaB protein and mRNA expressions in the brain of mice with viral encephalitis (P<0.05), and the effect was even more obvious at the dose of 5 mg/kg (P<0.01).</p><p><b>CONCLUSION</b>Shuanghuanglian injection can reduce the expression of NF-kappaB in the brain of mice with viral encephalitis in a dose- and time-dependent manner.</p>
