【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.

Objective To assess the value of carcinoembryonic antigen (CEA) level,liquid based cytology examination and combining 2 methods in predicting advanced pancreatic cystic neoplasms (PCNs).Methods The clinical data of 78 patients pathologically confirmed with PCN who underwent surgical resection after EUS-FNA and cyst fluid analysis in Shanghai Changhai Hospital,from January 2006 to June 2017 were collected and analyzed,including 32 (A-PCNs) patients and 46 non A-PCNs patients.The comparisons on the CEA level in the cyst fluid and liquid based cytology between the two groups were performed.ROC curve for CEA level in cyst fluid was applied and under curve area was calculated.Sensitive,specificity and accuracy were applied to assess the diagnosis value of 2 methods in predicting A-PCNs.Results In 35 patients,the difference on cyst fluid CEA level was statistically significant between 9 A-PCNs and 26 non A PCNs patients) [(1419.9 ± 1416.9) μg/L vs (316.0 ± 475.2) μg/L,P =0.049].Based on ROC curve,CEA ＞ 418.9 ng/ml could help to predicting A-PCNs with the sensitivity of 85.7％,specificity of 73.1％,and accuracy of 75.8％ as the cutoff value,and the area under ROC curve was 0.863.Liquid based cytology were performed in 27 A-PCNs patients and 33 non A PCNs patients,and the positive rate had statistical difference between 2 groups (48.1 vs 9.1％,P =0.001).The sensitivity,specificity and diagnostic accuracy for liquid-based cytology for diagnosing A-PCNs were 48.1％,90.9％,and 55.1％.Cyst fluid CEA combined with liquid based cytology can effectively diagnose A-PCN,and the sensitivity,specificity,and diagnostic accuracy were 100％,64.7％ and 76.0％.Conclusions Liquid-based cytology and cyst fluid CEA level were useful in predicting A-PCNs to a certain degree.Combining 2 methods could improve the sensitivity and accuracy in predicting A-PCNs.

Objective To explore the effects of systematic nursing intervention on psychology and quality of life in primary liver cancer patients undergoing surgery. Methods From January 2014 to December 2016, a total of 160 primary liver cancer patients undergoing surgery were selected as subjects by purposive sampling. All of the patients were divided into observation group and control group by the random number table, 80 cases in each group. Patients of control group were treated with the perioperative conventional nursing. On the basis, patients of observation group accepted systematic nursing intervention. We assessed patients in two groups with the SDS, SAS, Quality of Life of Cancer Patient Core Scale before and after intervention. Results After intervention, the score of SDS and SAS of patients in the observation group was lower than that of the control group with significant differences (P<0.01). Besides, the score of general health, physical functioning, role functioning, emotional functioning, cognitive functioning of patients in the observation group were significantly higher than those of the control group (P<0.05). Conclusions Systematic nursing intervention can improve negative emotions and quality of life of patients ,which is worthy of generalization and application.

Objective:The aim of this paper is to analyze and evaluate the equity and utilization efficiency of public health resource allocation in 31 provinces and cities in China, and provides reference and basis for public health resource allocation planning. Methods:The allocation of public health resources was evaluated by cluster anal-ysis and used data envelopment analysis was to explore the efficiency of public health resource allocation. Results:The degree of aggregation of public health resources in densely populated and economically developed provinces and cities were greater than or close to 1 , and the difference with the population concentration was mostly less than 0 . The degrees of aggregation in less economically backward provinces were less than 1 , and the difference with the popula-tion concentration was mostly more than 0 . The average technical efficiency of public health resource allocation was 0. 44, and the mean of pure technical efficiency and scale efficiency were 0. 74 and 0. 64 respectively. Conclusion:The degrees of aggregation of public health resources in economically developed provinces and cities are higher, but the corresponding population is poorly distributed based on population distribution. For economically backward prov-inces and cities, the geographical availability of public health resources is poor. In addition, due to unreasonable re-source allocation structure and proportion, public health resources configuration efficiency is relatively low.

Objective:To investigate the relationship between problem behaviorand father-child relationship in 4-6-year-oldchildren. Methods:Totally 102 children were recruited in a kindergarten in Beijing,with 36 aged four,36 aged five,30 aged six and 55 being boys and 47 being girls. Child Behavior Checklist (CBCL)was used to measure preschoolers'problem behaviors,and Family Relations Index (FRI)was adopted to assess children's rela-tionship with their fathers. Results:There were 41,49,and 12 children being classified as negative,neutral and posi-tive father-child relation respectively. Kruskal-Wallis Test revealed that there was no significant difference in scores of 3 CBCL subtests and 8 factors (P>0. 05 )among 4-,5-,and 6-year-old children. Children with negative father-child relationship scored higher on CBCL problem behavior subtests than those with neutral father-child relationship[30. 5 (7. 0,58. 0)vs. 16. 0 (0. 0,69. 0),P<0. 05 ]. They alsoscored higher on withdrawn behavior than children with neutralor positive father-child relationship [3. 0 (0. 0,4. 0)vs. 1. 0 (0. 0,6. 0),1. 0 (0. 0,4. 0),P<0. 05] . Mann-Whitney U Test manifested that boys scored higher in attention problem than girls (P<0. 0 1 ),but no gen-der difference was found in the other problem behaviors. Kruskal-Wallis Test showed that boys with negative father-child relationship scored higher than those with neutral father-child relationship on problem behavior subtest,anxie-ty-depression,attention problem,and internalized problem (Ps<0. 05 ). Boys with negative father-child relationship scored higher than those with neutraland positivefather-child relationship on withdrawn behavior (Ps <0. 05 ). No difference was found whether in CBCL subtests or problem behavior factors for girls with different types of father-child relationship. Conclusion:It suggests that the children with negative father-child relationship display more problem behavior and withdrawn symptoms;boys have more attention problems than girls;compared with girls, boys'problem behavior may be more closely related to therelationship with their father.

Objective To establish new classification criteria for early rheumatoid arthritis (E-RA) based on large samples of early inflammatory arthritis patients and to evaluate the value of this criteria in China.Methods Patients who had arthritic complaints with disease duration less than one year were enrolled.They were divided into RA group and non-RA group according to the clinical diagnosis by experienced rheumatologists.The clinical and laboratory parameters were analyzed and those with high sensitivity or specificity were selected as the new classification criteria.Statistical analysis was carried out by using t test,x2 test and Logistic regression.Results ① A total of 803 patients with early inflammatory arthritis were included in this study.Five hundreds and fourteen patients were diagnosed as early RA and 251 were diagnosed as other rheumatic diseases,and the diagnosis of 38 patients remained unestablished by the end of follow-up.② New E-RA classification criteria were established based on the parameters with high sensitivity and/or specificity.The sensitivity of the new E-RA criteria was 84.4％,which was higher than 1987 ACR criteria (58.0％),while the corresponding specificities were similar,which were 87.4％ and 93.6％ respectively.③ Compared with the complex scoring system of 2010 ACR/EULAR criteria,the E-RA criteria was more simple and practical.The diagnostic sensitivity and specificity of E-RA criteria were higher than those of 2010 ACR/EULAR criteria reported in the literatures.④ New classification criteria based on scoring system using Logistic regression analysis was established.The sensitivity of this criteria was 86.4％,which was higher than 1987 ACR criteria (58.0％).Conclusion The diagnostic value of the E-RA criteria developed in this study for early RA is better than 1987 ACR criteria,and is more simple than 2010 ACR/EULAR criteria.It may be used as a new classification criteria for early RA diagnosis.

OBJECTIVETo investigate the pathogenesis and immunogenicity of H9N2 influenza virus A/Guangzhou/333/99 (a reassortant of G1 and G9 viruses isolated from a female patient in 1999) in a mouse model of infection.

METHODSMice were infected with increasing virus titers. Viral load in the lungs and trachea was determined by EID50 assay. Pulmonary histopathology was assessed by hematoxylin-eosin staining. Anti-HI antibody titers and T-cell responses to viral HA were determined by ELISPOT and confirmed by flow cytometry.

RESULTSMice presented a mild syndrome after intranasal infection with A/Guangzhou/333/99 (H9N2) influenza virus. Virus was detected in the trachea and lungs of mice harvested on days 3, 6, and 9 post-infection. A T-cell response to viral HA was detected on day 6 and H9 HA-specific CD(4+) T-cells predominated. Seroconversion was detected after 14 days and antibody persisted for at least 28 weeks.

CONCLUSIONOur results suggest that H9N2 (A/Guangzhou/333/99) can replicate in the murine respiratory tract without prior adaptation, and both humoral and cell-mediated immunity play an important role in the immune response.
