Objective: To analyze the survival of newly diagnosed malignant tumors in cancer registration areas of Hubei Province from 2013 to 2015. Methods: From January 1, 2013 to December 31, 2015, all newly diagnosed malignant tumors were collected from cancer registration areas in Hubei Province, and patients were followed up using a combination of active and passive methods. Cancer survival was analyzed using the strs package in Stata software. Observed and expected survival were calculated using the life table and Ederer Ⅱ methods, and the difference in survival rate of patients with different sex, age, urban and rural areas and different cancer species was compared. Results: From 2013 to 2015, 83 987 new malignant tumors were diagnosed in cancer registration areas in Hubei Province, including 45 742 males (54.46%) and 38245 females (45.54%). The overall 5-year relative survival rate was 41.46%, 34.43% for men and 49.63% for women. With the increase of age, the observed survival rate and relative survival rate of patients of different genders showed a decreasing trend. The 5-year relative survival rate of patients with malignant tumors was 47.58% in urban areas and 26.58% in rural areas. The observed survival rate and relative survival rate in rural areas were significantly lower than those in urban areas. The overall 5-year relative survival rates for common malignancies were 20.61% for lung cancer, 15.36% for liver cancer, 22.89% for esophageal cancer, 34.92% for gastric cancer, and 54.87% for colorectal cancer. In addition, the 5-year relative survival rates of common malignant tumors in women were 78.65% for breast cancer and 52.55% for cervical cancer. Conclusions: In Hubei Province, the survival rate of malignant tumors is different among different genders, regions, age groups and cancer species. Prevention and treatment and health education should be strengthened for malignant tumor patients in rural areas and those with high incidence and low survival rate such as liver cancer and lung cancer, and relevant strategies should be formulated according to the gender and age distribution characteristics of different cancer species.

Objective: To investigate the relationship between body mass index (BMI) and sexual development in Chinese children. Methods: A nationwide multicenter and population-based large cross-sectional study was conducted in 13 provinces, autonomous regions and municipalities of China from January 2017 to December 2018. Data on sex, age, height, weight were collected, BMI was calculated and sexual characteristics were analyzed. The subjects were divided into four groups based on age, including ages 3-<6 years, 6-<10 years, 10-<15 years and 15-<18 years. Multiple Logistic regression models were used for evaluating the associations of BMI with sexual development in children. Dichotomous Logistic regression was used to compare the differences in the distribution of early and non-early puberty among normal weight, overweight and obese groups. Curves were drawn to analyze the relationship between the percentage of early puberty and BMI distribution in girls and boys at different Tanner stages. Results: A total of 208 179 healthy children (96 471 girls and 111 708 boys) were enrolled in this study. The OR values of B2, B3 and B4+ in overweight girls were 1.72 (95%CI: 1.56-1.89), 3.19 (95%CI: 2.86-3.57), 7.14 (95%CI: 6.33-8.05) and in obese girls were 2.05 (95%CI: 1.88-2.24), 4.98 (95%CI: 4.49-5.53), 11.21 (95%CI: 9.98-12.59), respectively; while the OR values of G2, G3, G4+ in overweight boys were 1.27 (95%CI: 1.17-1.38), 1.52 (95%CI: 1.36-1.70), 1.88 (95%CI: 1.66-2.14) and in obese boys were 1.27 (95%CI: 1.17-1.37), 1.59 (95%CI: 1.43-1.78), and 1.93 (95%CI: 1.70-2.18) (compared with normal weight Tanner 1 group,all P<0.01). Analysis in different age groups found that OR values of obese girls at B2 stage and boys at G2 stage were 2.02 (95%CI: 1.06-3.86) and 2.32 (95%CI:1.05-5.12) in preschool children aged 3-<6 years, respectively (both P<0.05). And in the age group of 6-10 years, overweight girls had a 5.45-fold risk and obese girls had a 12.54-fold risk of B3 stage compared to girls with normal BMI. Compared with normal weight children, the risk of early puberty was 2.67 times higher in overweight girls, 3.63 times higher in obese girls, and 1.22 times higher in overweight boys, 1.35 times higher in obese boys (all P<0.01). Among the children at each Tanner stages, the percentage of early puberty increased with the increase of BMI, from 5.7% (80/1 397), 16.1% (48/299), 13.8% (27/195) to 25.7% (198/769), 65.1% (209/321), 65.4% (157/240) in girls aged 8-<9, 10-<11 and 11-<12 years, and 6.6% (34/513), 18.7% (51/273), 21.6% (57/264) to 13.3% (96/722), 46.4% (140/302), 47.5% (105/221) in boys aged 9-<10, 12-<13 and 13-<14 years, respectively. Conclusions: BMI is positively correlated with sexual development in both Chinese boys and girls, and the correlation is stronger in girls. Obesity is a risk factor for precocious puberty in preschool children aged 3-<6 years, and 6-<10 years of age is a high risk period for early development in obese girls.

OBJECTIVE: The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire (FFQ) among Chinese children aged 12-17 years. METHODS: A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls (24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children (N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients (ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. RESULTS: For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman's correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from -0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. CONCLUSION The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.

Objective To investigate the distribution of insulin resistance (HOMA-IR) index and its influencing factorsamong middle and old aged people with normal glucose and to provide the basis for early screening and prevention of type 2diabetes. Methods A total of 229 residents were selected with health records showed normal blood glucose (fasting bloodglucose < 7.0mmol/L, postprandial 2h blood glucose<11.1 mmol/L) and more than 40 years old from July, 2012 to June,2015. Height, weight, waist and hip circumference, and the fasting plasma glucose (FPG), insulin (FINS), lowdensity lipoprotein (LDL), uric acid, tumor necrosis factor (TNF) and interleukin -6 (IL-6) were recorded to analyzethe distribution of HOMA-IR and its influencing factors. Results Totally 229 people were included, of which 113 were male(49.34%), 116 female(50.66%) . The average age was(63.58 + 8.85) years old. The average HOMA-IR index was 0.94(1.08) and there were 21 people that HOMA-IR exceed the standard (HOMA-IR≥2.68), accounting for 9.17%.TheHOMA-IR index of different gender, age, waist circumference, hip circumference, uric acid in the elderly had significantdifference (P < 0.05) .Multiple linear regression analysis showed that HOMA-IR index was positively correlated withfemale, waist circumference and IL-6 and was negatively correlated with age. Conclusion The possibility of IR was higherin women with relatively low age, female, central obesity and high IL-6 levels among the middle and old aged people withnormal blood glucose.

In this study, we investigated the protective effect of the antioxidant N-acetyl-L-cysteine (NAC) on the lung inflammation caused by ozone (O) exposure in mice. Thirty-two C57BL/6 mice were randomly divided into control group, Ogroup, O+NAC group and NAC group. Mice were exposed to O(1.0 ppm) or fresh air for 3 h on the day 1, day 3 and day 5, respectively. NAC (100 mg/kg) was intraperitoneally applied to the mice 1 h before each exposure. At 24 h after the 3-time exposure, the alveolar wall structure was severely damaged and the infiltrated inflammatory cells were apparent perivascularly and peribronchiolarly. Significant increases in the total white blood cell count, macrophage, lymphocyte and neutrophil counts, as well as total protein concentration were observed in the bronchoalveolar lavage fluid (BALF) (P < 0.05). The IL-6, IL-8 (P < 0.01) and MDA levels (P < 0.05) in the lung homogenates were elevated coherently. Administration of NAC could attenuate the alveolar wall structure damage induced by Oexposure and reduce the amount of infiltrated inflammatory cells, total and differential leukocyte counts (P < 0.05), as well as the IL-6, IL-8 (P < 0.01) and MDA release (P < 0.05). Western blotting results showed that the Oexposure up-regulated the p38 MAPK and NF-κB p65 protein expression in the lung tissue of mice (P < 0.05), which could be alleviated by NAC (P < 0.05). These results indicated that NAC could protect against O-induced pulmonary inflammation in mice. The beneficial effect of NAC might be related with the p38 MAPK and NF-κB p65 signal pathway.

To investigate the effect and possible mechanism of echinacoside-containing serum on the osteogenic differentiation in rat bone marrow mesenchymal stem cells. Rat bone marrow mesenchymal stem cells were cultivated by the whole bone marrow adherence method. The 3rd generation of cells were divided into 3 groups: the blank control group, the classic osteogenic-induced group and the 10% echinacoside-containing serum group. The expression of alkaline phosphatase and osteocalcin were detected by ELISA. The ex- pression of ZHX, protein was detected by Western blot technique. RT-PCR technique was used to detect the expression of ZHX₃mRNA. According to the result, the expressions of the alkaline phosphatase and osteocalcin in the classic osteogenic-induced group and the 10% echinacoside-containing serum group were significantly higher than that of the blank control group (P <0. 01). And expressions of the alkaline phosphatase activity and osteocalcin in the 10% echinacoside-containing serum group were significantly higher than that in the classic osteogenic-induced group (P < 0.01). Meanwhile, the classic osteogenic-induced group and the 10% echinacoside-containing serum group showed obviously higher ZHX₃ protain and mRNA expression than that of the black control group, with significant differences (P < 0.01); the 10% echinacoside-containing serum group showed obviously higher ZHX₃ protain and mRNA expression than that of the classic osteogenic-induced group, with a significant difference (P < 0.01). In conclusion, 10% echinacoside-containing serum can promote the differentiation of the bone marrow mesenchymal stem cells cultured in vitro. Its mechanism may be correlated with the increase in the ZHX₃expression.

OBJECTIVETo investigate the clinical feasibility of cell-free fetal DNA (cffDNA)-based noninvasive prenatal diagnosis of β-thalassemia.

METHODSNine samples of amniotic fluid were obtained to detect the 8 common and 9 relatively rare mutation sites of β-thalassaemia in Guangdong Province. The maternal blood samples were also collected for extracting and purification of the cffDNA, and a duplex PCR was performed using 3 pairs of primers and the fetal β-globin genotype was analyzed by reverse dot-blot hybridization.

RESULTSAmong the 9 cases, 5 showed fetal genotypes of β-thalassemia inherited from the father by examination of the amniotic fluid, and 2 fetuses were identified to have β-thalassemia genes inherited from the father determined based on the cffDNA in the maternal blood.

CONCLUSIONSThe cffDNA-based noninvasive prenatal diagnosis is feasible for β-thalassemia, but the contamination of the maternal background DNA results in a low detection rate.
