Abstract
Objective: We planned to evaluate the effectiveness of moving epidemic method (MEM) in calculating influenza epidemic threshold of 7 climatic zones in China mainland. Methods: The positive rate of influenza virus was obtained from the National Influenza Surveillance Network System from 2010/2011 to 2017/2018. We divided the 31 provinces into 7 climatic zones according to previous literatures and applied MEM to calculate the influenza epidemic threshold of 2018/2019 influenza season for these climatic zones. Sensitivity, specificity, positive predictive value and negative predictive value were calculated to evaluate the effectiveness of MEM. Results: Pre-epidemic threshold (the positive rate of influenza virus) varied from 9.66% (temperate zone) to 16.36% (subtropical zone) for 2018/2019 influenza season. The gap between pre-epidemic and post-epidemic thresholds was less than 5% except for plateau zone. The sensitivity was 86.16% (95CI:66.81%-98.23%), the specificity was 94.92% (95CI: 91.13%-98.41%), the positive predictive value was 89.87% (95%CI: 84.39%-94.38%), the negative predictive value was 92.96% (95%CI: 84.46%-99.17%). Conclusion: Overall, moving epidemic Method performs well in calculating influenza epidemic threshold in China, much better than the previous study.

Abstract
Objective: To systematically review the mortality burden study of influenza in mainland China. Method: "influenza", "flu", "H1N1", "pandemic", "mortality", "death", "fatality", "burden", "China" and "Chinese" were used as keywords, and a systematic literature search was conducted to identify articles in three English databases (PubMed, Web of Science and Embase) and three Chinese database (CNKI, WanFang and VIP) during 1990-2018 (excluding Hong Kong, Macao and Taiwan). The language of literature was restricted to Chinese and English. The inclusion criteria were human-oriented researches with method based on population, and research indexes included mortality and excess mortality. The exclusion criteria were non-primary research materials, predictive research and research on the burden of avian influenza related deaths. A total of 17 literatures were included, and the basic information to descriptive characteristics, methodology of modeling and the corresponding results were extracted. Results: All the 17 studies adopted indirect statistical models, with 14 of which adopted the regression model, and all the research index was excess mortality. All causes (16 studies), respiratory and circulatory diseases (14 studies) and pneumonia and influenza (10 studies) were the main causes of death associated with influenza. Influenza associated mortality burden in the elderly was higher, with the lowest excess mortality rates of all causes, respiratory and circulatory diseases, pneumonia and influenza being 49.57, 30.80 and 0.69 per 100 000 people, and the highest rates being 228.16, 170.20 and 30.35 per 100 000 people, respectively. In the non-elderly, the corresponding lowest rates were -0.27, -0.08 and 0.04 per 100 000 people respectively, and the highest rates were 3.63, 2.6 and 0.91 per 100 000 people, respectively. The influenza-related excess mortality was higher in the north, with a minimum of 7.8 per 100 000 and a maximum of 18.0 per 100 000, and slightly lower in the south, with a minimum of 6.11 per 100 000 and a maximum of 18.7 per 100 000. There were also differences in deaths caused by different influenza virus subtypes, with influenza A(H3N2) and influenza B virus possibly posing a heavier mortality burden. Conclusions: Studies on influenza mortality burden is mainly based on indirect model and urban level in China. The mortality burden of influenza in the elderly, the northern and subtype A(H3N2) and B were more severe.

Abstract
Objectives: To understand the status of studies about influenza economic burden in mainland China and summarize their major results. Methods: The words of influenza, flu, cost, economic, burden, effectiveness, benefit, utility, China, and Chinese, were used as search keywords. Journal papers published during 2000-2018 were searched from Chinese electronic databases (CNKI and Wanfang) and English electronic databases (PubMed, Web of science, EconLit and Cochrane Library). The language of literature was restricted to Chinese and English. A total of 23 effective documents were included, and the descriptive characteristics, research indexes and methods included in the literature were analyzed. The monetary unit used in this review is Chinese Yuan (CNY). Results: The 23 study sites were mainly in the relatively developed and populous regions. The total cost per capita of laboratory-confirmed influenza,of all age-group was reported in 6 literatures, and only 4 literatures reported it in out-patients (range: 768.0-999.9 CNY), Only one study reported this indicator in inpatients (9 832.0 CNY). One literature reported the total cost per capita of influenza-like illness,, which was 205.1 CNY. And one literature reported that the direct medical cost of inpatients per capita in children under 5 years of age was 6 072.0 CNY while two literature reported this index for the elderly over 60 years of age, ranging from 14 250.0 to 19 349.1 CNY. Four articles reported the economic burden of influenza in urban and rural areas, one of which showed that the related expenses of urban influenza inpatients accounted for 31% of the average annual income, while which for the rural flow was 113%. Conclusion: The average economic burden of lab-confirmed influenza case is higher than that of influenza-like illness, and there are differences in outpatient indirect expenses and inpatients direct medical expenses. The direct medical burden for the hospitalized 60-years-and-beyond influenza case group is heavier thar other age group. By region, the influenza associated individual economic burden in rural area is higher than that of urban area..

Abstract
Abstract
Aims
The possibility of endovascular reconstruction of aortic valve, sinus of Valsalva, and ascending aorta by a minimal-invasive single endograft has not been proven in vivo. Combining our own long-term experiences from transcatheter aortic valve replacement (TAVR) and Thoracic Endovascular Repair (TEVAR) for ascending and arch dissection, we designed the special endo-graft: a novel one-piece valved-fenestrated-bifurcated endografting, and tried to endovascularly reconstruct the area from Left ventricular outflow tract to aortic arch in animal experiments.
Methods and results
For 20 healthy adult female pigs weighed between 62.3±2.2 kilograms, we did aortic compute tomography angiography (CTA) examinations and measured morphologic parameters of aortic root. Then we accordingly customized the valved-fenestrated-bifurcated endograft. The endograft was delivered through transapical access and endovascularly reconstructed the segment from aortic valve to proximal part of aortic arch. The overall technical success rate was 95% because of one case of delivery system failure. Instant transesophageal echography (TEE) and aortic CTA confirmed ideal position of the endograft, satisfactory function of aortic valve, and the patency of coronary arteries in all subjects. During follow-up, 12 subjects were sacrificed according to the plan and seven were followed up for 8.1±3.6 months. There was one unplanned death of cardiac infection (unplanned mortality: 5.3%). Follow-up re-examinations (aortic CTA, cardiac ultrasound, and electrocardiogram) found no adverse events. Among 12 sacrificed subjects, there was no evidence of fenestrations alignment lost and no myocardial ischemia according to the pathological analysis.
Conclusion
The novel one-piece valved-fenestrated-bifurcated endografting might be feasible for minimal-invasive reconstruction of aortic root in animal models, thus provided a prospect to simultaneously treat pathologies involving aortic valve and aortic root in endovascular way.

Abstract
Canine kobuvirus (CaKoV) is a newly emerging virus in dogs, which relates to the diarrhea of dogs. To investigate the CaKoV infection in dog population, fecal samples of dogs were collected from three provinces of China in 2015. The results of genetic analysis based on the complete VP1 gene showed that six CaKoVs isolates in this study were closely related with the Chinese canine originated isolate CH1 (90.6%-91.9% nucleotide identities). The phylogenetic analysis demonstrated that the Chinese isolates clustered into a unique branch compared with isolates from other countries. The present study suggested that the CaKoVs had established infection in Chinese dog population. The systematic epidemiological investigation should be further carried out to evaluate the prevalence of the CaKoV infection in China.

Abstract
Objective: To predict the tumor neoantigen peptides in hepatocellular carcinoma (HCC), and examine their specific immune effects against the tumor cells without injury to normal cells. Methods: The data of whole-genome sequencing and exome sequencing of HCC tumor and matched non-tumor liver tissues were analyzed to confirm the HCC-associated somatic mutations. Based on the HLA phenotype of the patients, we used NetMHC software to predict the neoantigen epitopes with high binding affinity to their MHC-I molecules. The predicted peptides with mutation sites included were synthesized. GPL10687 platform was applied to examine the gene expression difference between tumor and normal tissues of the selected genes in GSE25097, one of the GEO databases. The quantitative real-time PCR (qRT-qPCR) and immunohistochemistry were used to confirm the expressions in tumors and normal tissues of the selected genes. By using the predicted peptides, we induced the generation of antigen-specific CD8(+) cytotoxic T lymphocytes (CTLs) and examined their specific effects against tumor cells. Results: The mutation frequency of TP53 (tumor protein p53) was 40%, and LAMA3 (Laminin Subunit Alpha 3) was 8% in the analyzed HCC tissues. In GSE25097 database, TP53 and LAMA3 mRNA levels in tumors were 1.57±0.02 and 1.37±0.10, which were significantly increased than those in matched no-tumor tissue (0.54±0.01 and 0.36±0.01, P<0.05). The differences of expression levels of TP53 and LAMA3 in tumor and no-tumor tissues were validated by using qRT-qPCR and immunohistochemistry in 10 HCC tissues. The mRNA levels of TP53 and LAMA3 in tumors were 0.24±0.03 and 0.13±0.06, which were significantly elevated than those in matched no-tumor tissue (0.11±0.01 and 0.01±0.01, P<0.05). Among the Chinese population, HLA-A2 and HLA-A11 and HLA-A24 accounted for 70%, representing the major MHC-I molecules. The CTLs induced by predicted peptides showed cytotoxicity to the targets pulsed with mutated peptide, with no effect on the target pulsed with normal peptide and on normal cells. Conclusions: TP53 and LAMA3 existed relative higher mutation frequency in HCC, and expressed higher in tumor tissues. The induced CTLs by predicted peptides derived from mutation-associated protein could specific kill the target cells without injury to normal cells.

Abstract
Objective: There is no effective therapy for patients with advanced medullary thyroid carcinoma (MTC). Vandetanib,a novel multitargeted receptor tyrosine kinase inhibitor, has previously shown antitumor activity in phase Ⅱ studies of patients with advanced MTC. This study was to evaluate the efficacy and the safety of vandetanib on advanced MTC. Methods: This study was an open, international multi-center phase Ⅲ clinical trial and the study number was NCT01298323. The single-center study was a sub-group analysis of the international study, which was conducted on 9 pathologically confirmed advanced MTC patients by Cancer Hospital Chinese Academy of Medical Sciences between March 2012 and October 2017. Vandetanib (300 mg) was orally administered daily till death or withdrawal. The efficacy was evaluated according to RECIST criteria and the adverse events were evaluated according to NCI criteria. Results: The objective response rate was 3/9,and the disease control rate was 4/9. The median progression-free survival was 44 months. All patients who had the elevated levels of calcitonin (CTN) and carcino-embryonic antigen (CEA) before treatment began to show the decreases in the level of CTN and CEA after 3 months and later showed again the increases in the levels of both tumor markers with tumor progression. By ROC curve analysis, CTN was of statistically significance(P<0.05, 95%CI 0.558-0.834), but CEA was not(P>0.05). Adverse events were generally mild (grade 1 or 2),including hypertension (9 cases),skin rash (9 cases), and diarrhea (6 cases). Two patients developed grade 3 elevation of serum glutamate pyruvate transaminase and one patient developed grade 3 elevation of drug-related bowel disease. No grade 4 drug-related adverse event occurred. Conclusions: Vandetanib is effective and well tolerated for patients with locally advanced or metastatic MTC who have no chance for surgery. This indicates the increase of CTN is clinically relevant to disease progression, but the number of patients are extremely low, and, therefore further research is needed. Long-term use of vandetanib may cause resistance.

Abstract
1. The aim of the present study was to investigate the effects of different starch sources (corn, wheat, and rice) on the blood glucose level, glycogen content of liver and muscle, expression of GSK-3β and FAS mRNA, abdominal fat weight and abdominal fat deposition in broiler chickens. 2. A total of 360, one-day-old AA (Arbor Acres) broiler chickens were randomly assigned to three treatment groups, each with six replicates, consisting of 20 chickens per replicate, and fed either a corn-, wheat- or rice-based diet for 21 days. The chickens were then subdivided into groups A and B, and the chickens in these two subgroups were processed or sampled for 28 days, respectively. 3. The results indicated that post-prandial time significantly affected the glucose concentration, glycogen content in the liver and breast muscle and expression of GSK-3β and FAS mRNAs (P < 0.05). The expression of the GSK-3β gene in the chicken liver of the corn-based diet group was higher (P < 0.05) than that in the wheat-based diet group, and the expression of the FAS gene in the corn-based diet group was lower (P < 0.05) than that in the wheat-based and rice-based diet groups. Abdominal fat weight and deposition in the corn-based diet group were lower than those of the wheat-based and rice-based diet groups, but these differences were not significant (P > 0.05). 4. The results suggested that the efficiency of glucose absorption in animals might have an effect on the fat deposition efficiency in the liver and that diets with different starch sources might affect fat deposition in chickens.

Abstract
Differentiated thyroid cancer (DTC) is the most frequently diagnosed thyroid cancer. With the development of the imaging technology and fine needle aspiration, early diagnosis rate of DTC is increasing. Most patients have favorable prognosis for DTC's low-invasion. TNM staging is more widely used for predicting mortality than predicting recurrence. In 2008, it was suggested that recurrence risks for DTC should be assessed based on the results of dynamic monitoring treatment response. The validity of dynamic risk stratification (DRS) has been supported by different researches in various countries and DRS is recommended in 2015 American Thyroid Association Management Guidelines. Long-term DRS in patients with DTC make individual management possible.

Abstract
Objective: To explore the ability of computed-tomography (CT) radiomic features to predict the Epidermal growth factor receptor (EGFR) mutation status and the therapeutic response of advanced lung adenocarcinoma to EGFR- Tyrosine kinase inhibitors (TKIs) treatment. Methods: A retrospective analysis was performed on 253 patients diagnosed as advanced lung adenocarcinoma, who underwent EGFR mutation detection, and those with EGFR sensitive mutation were treated with TKIs. Using the Lasso regression model and the 10 fold cross-validation method, the radiomic features of predicted EGFR mutation status and the screening of TKIs for sensitive populations were obtained. 715 radiomic features were extracted from unenhanced, arterial phase and venous phase, respectively. Results: The area under curve (AUC) values of the multi-phases including unenhanced, arterial phase and venous phase of the EGFR mutation status validation group were 0.763, 0.807 and 0.808, respectively. The number of radiomic features extracted from the multi-phases were 5, 18 and 23, respectively, which could distinguish the EGFR mutation status. The AUC values of the multi-phases of the EGFR-TKIs sensitive validation group were 0.730, 0.833 and 0.895, respectively. The number of radiomic features extracted from the multi-phases were 3, 7 and 22, respectively, which can be used to screen the superior population for TKIs treatment. The efficiency of radiomic features extracted from venous phase in predicting EGFR mutant status and EGFR-TKIs sensitivity was significantly superior than those of unenhanced and arterial phase. Conclusions: The radiomic features of CT scanning can be used as the radiomics biomarker to predict the EGFR mutation status of lung adenocarcinoma and to further screen the dominant population in TKIs therapy, which provides the basis for targeted therapy.

Abstract
Objective: To study serum zinc level in pregnancy and umbilical cord blood and their association with newborn birth weight. Methods: Pregnant women accepting obstetric examination in Ma'anshan Maternal and Child Care Center were recruited from May 2013 to September 2014. The follow up was conducted during their first, second and third trimesters of pregnancy and the self-designed questionnaire was used to collect information of social and demographic characteristics. Blood samples in the first, second pregnancy period and umbilical cord blood samples were collected and serum concentrations of zinc were assayed. 3 239 mother-infant entered the final analysis. We divided serum zinc level into low (<P(25)), medium (P(25)-P(75)) and high (>P(75)) groups according to their exposure concentrations at each trimesters. Non-conditional multivariate logistic regression model was conducted to evaluate the association between serum zinc level in first, second trimesters of pregnancy and umbilical cord blood with small for gestational age (SGA) and large for gestational age (LGA). Results: Serum zinc level in P(50) (P(25)-P(75)) during the first, second trimesters and cord blood were 1 016.18 (907.09-1 145.60), 813.36 (732.47-897.89) and 903.44 (808.71-1 015.64) μg/L, respectively. The prevalence of zinc deficiency during the first, second trimesters and cord blood were 1.5% (44/2 957), 15.9% (492/3 087) and 6.5% (176/2 707), respectively. The prevalence of total SGA and LGA were 9.7% (313/3 239) and 16.5% (536/3 239), respectively. Compared to high-level serum zinc group, the risk of SGA (OR (95%CI) in low-level serum zinc group during first trimesters was 1.51 (1.05-2.19)). Serum zinc level among second pregnancy period and umbilical cord blood had no statistically significant effect on SGA and LGA (both P values >0.05). Conclusion: Zinc nutritional status of pregnant women in Ma'anshan city was at a good level. The low serum zinc level in first trimester increased the risk of SGA.

Abstract
Seasonal influenza vaccination is the most effective way to prevent influenza virus infection and its complications. Currently, China has licensed trivalent (IIV3) and quadrivalent inactivated influenza vaccine (IIV4), including split-virus influenza vaccine and subunit vaccine. In most parts of China, influenza vaccine is a category Ⅱ vaccine, which means influenza vaccination is voluntary, and recipients need to pay for it. To strengthen the technical guidance for prevention and control of influenza and the operational research on influenza vaccination in China, the National Immunization Advisory Committee (NIAC), Influenza Vaccine Technical Working Group (TWG), updated the 2014 technical guidelines and compiled the "Technical guidelines for seasonal influenza vaccination in China (2018-2019)" , based on most recent existing scientific evidences. The main updates include: epidemiology and disease burden of influenza, types of influenza vaccines, northern hemisphere influenza vaccination composition for the 2018-2019 season, and, IIV3 and IIV4 vaccines'major immune responses, durability of immunity, immunogenicity, vaccine efficacy, effectiveness, safety, cost-effectiveness and cost-benefit. The recommendations include: Points of Vaccination clinics (PoVs) should provide influenza vaccination to all persons aged 6 months and above who are willing to be vaccinated and do not have contraindications. No preferential recommendation is made for any influenza vaccine product for persons who can accept ≥1 licensed, recommended, and appropriate products. To decrease the risk of severe infections and complications due to influenza virus infection among high risk groups, the recommendations prioritize seasonal influenza vaccination for children aged 6-60 months, adults ≥60 years of age, persons with specific chronic diseases, healthcare workers, the family members and caregivers of infants <6 months of age, and pregnant women or women who plan to pregnant during the influenza season. Children aged 6 months to 8 years old require 2 doses of influenza vaccine administered a minimum of 4 weeks apart during their first season of vaccination for optimal protection. If they were vaccinated in previous influenza season, 1 dose is recommended. People ≥ 9 years old require 1 dose of influenza vaccine. It is recommended that people receive their influenza vaccination by the end of October. Influenza vaccination should be offered as soon as the vaccination is available. Influenza vaccination should continue to be available for those unable to be vaccinated before the end of October during the whole season. Influenza vaccine is also recommended for use in pregnant women during any trimester. These guidelines are intended for CDC members who are working on influenza control and prevention, PoVs members, healthcare workers from the departments of pediatrics, internal medicine, and infectious diseases, and members of maternity and child care institutions at all levels.

Abstract
Objective: To analyze the epidemiological characteristics of notifiable infectious diseases among Chinese students from 2011 to 2016 and to provide reference for the effective prevention and control programs on infectious disease among students. Methods: Both morbidity and mortality of notifiable infectious diseases among Chinese students aged 6-22 years from 2011 to 2016 were analyzed, with main characteristics of the disease described. Results: During 2011 to 2016, morbidities of Categories A, B and C infectious diseases among the Chinese students aged 6-22 years showed a decreasing trend, from 248.24/100 000 in 2012 to 158.57/100 000 in 2016. Mortality rates of Category A, B and C infectious diseases had also decreased from 0.12/100 000 in 2011 to 0.07/100 000 in 2016. The average morbidity of the top four diseases from Category A and B infectious diseases appeared as: tuberculosis (16.24/100 000), scarlet fever (9.39/100 000), hepatitis B (7.69/100 000) and bacillary and amebic dysentery (7.15/100 000). The average rates of mortality on the top four diseases appeared as: rabies (0.044 8/100 000), HIV/AIDS (0.027 7/100 000), tuberculosis (0.008 0/100 000) and Japanese encephalitis (0.005 9/100 000). The average rates of morbidity on the top four diseases appeared as: mumps (75.81/100 000), hand-foot-mouth disease (28.55/100 000), other infectious diarrhea (22.41/100 000) and influenza (15.67/100 000) in the Category C. Reported death cases were from hand-foot-mouth disease (11 cases), influenza (9 cases), mumps (1 case) and rubella (1 case). The prevalence rates varied among different student populations, with higher HIV/AIDS, hepatitis B and tuberculosis rates among college and senior high school students, while higher mumps, influenza and hand-foot-mouth disease rates among primary school and junior high school students. Conclusions: Both morbidity and mortality of notifiable infectious diseases among Chinese students aged 6-22 years had decreased significantly in 2011-2016. However, the major infectious diseases had become new challenges among students. HIV/AIDS had become a key infectious disease among college students and the relatively high prevalence of tuberculosis was seen in college and high school students.

Abstract
Objective: To investigate the clinical status of lymphoid tissue neoplasms patients with bacteria bloodstream infections, bacteriology and drug susceptibility results, and provide the basis for rational clinical anti-infection option. Methods: A retrospectively analysis of clinical data and bacterial susceptibility test results of patients with bacteria bloodstream infections from September 2010 to December 2014 was conducted. Results: A total of 134 cases including 107 patients with bloodstream infections were enrolled. 84 cases were male, 50 cases were female, the median age was 31 (12-71) years old. 112 cases were agranulocytosis, and 106 cases were severe agranulocytosis (ANC<0.1×10(9)/L) . 27 cases underwent hematopoietic stem cell transplantation, 100 cases received chemotherapy[33 cases with VD (I) CP±L (vincristine+daunorubicin/idarubicin + cyclophosphamide + prednison±asparaginasum) induction chemotherapy, 41 cases with intensive chemotherapy of Hyper-CVAD/MA or MA (mitoxantrone+cytarabine) , 26 cases with other chemotherapy regimens], and 7 cases were infected without chemotherapy. 10 patients discharged from hospital owing to treatment abandoning, 120 cases were cured through anti-infective therapy, 2 patients died of bacteria bloodstream infections, 1 patient died of sudden cardiac, and 1 patient died of GVHD after allogenic hematopoietic stem cell transplantation. A total of 144 strains were isolated, including 108 strains (75.0%) of Gram-negative bacteria and 36 strains (25.0%) of Gram-positive cocci. The susceptibility of Gram-negative bacteria to the carbapenems was 98.00%, and the adjustment treatment rate of carbapenems was 3.0%. The susceptibility of Gram-negative bacteria to the other antibiotics was 60.30%, and the adjustment treatment rate was 90.5%. The susceptibility of Grampositive cocci to the carbapenems was 49.3%, and to glycopeptides and linezolid was 100.0%. Comparing all patients'empirical use of antimicrobial agents with the drugs susceptibility results of blood cultures, 80.1% of the patients'initial drug selection was sensitive. Conclusion: The lymphoid neoplasms patients experienced bacteria bloodstream infections most often after receiving the chemotherapy regimens of treating acute lymphoblastic leukemia. The majority type of bacteria was Gram-negative bacteria. Drug susceptibility test showed that susceptibility of Gram-negative bacteria to the carbapenems was the highest, and the treatment adjustment rate was obviously lower. The susceptibility of Gram-positive cocci to glycopeptides and linezolid was high, and which could be applied to the patients with Gram-positive cocci sepsis on basis of susceptibility results in general.

Abstract
Seasonal influenza vaccination is the most effective way to prevent influenza virus infection and complications from infection. Currently, China has licensed trivalent inactivated influenza vaccine (IIV3) and quadrivalent inactivated influenza vaccine (IIV4), including split-virus influenza vaccine and subunit vaccine. Except for a few major cities, influenza vaccine is a category Ⅱ vaccine, which means influenza vaccination is voluntary, and recipients must pay for it. To strengthen the technical guidance for prevention and control of influenza and operational research on influenza vaccination in China, the National Immunization Advisory Committee (NIAC) Influenza Vaccine Technical Working Group (TWG), updated the 2014 technical guidelines and compiled the "Technical guidelines for seasonal influenza vaccination in China (2018-2019)" . The main updates in this version include: epidemiology, disease burden, types of influenza vaccines, northern hemisphere influenza vaccination composition for the 2018-2019 season, IIV3 and IIV4 immune response, durability of immunity, immunogenicity, vaccine efficacy, effectiveness, safety, cost-effectiveness and cost-benefit. The influenza vaccine TWG provided the recommendations for influenza vaccination for the 2018-2019 influenza season based on existing scientific evidence. The recommendations described in this report include the following: Points of Vaccination clinics (PoVs) should provide influenza vaccination to all persons aged 6 months and above who are willing to be vaccinated and do not have contraindications. No preferential recommendation is made for one influenza vaccine product over another for persons for whom more than one licensed, recommended, and appropriate product is available. To decrease the risk of severe infections and complications due to influenza virus infection among high risk groups, the recommendations prioritize seasonal influenza vaccination for children aged 6-59 months, adults ≥60 years of age, persons with specific chronic diseases, healthcare workers, the family members and caregivers of infants <6 months of age, and pregnant women or women who plan to become pregnant during the influenza season. Children aged 6 months through 8 years require 2 doses of influenza vaccine administered a minimum of 4 weeks apart during their first season of vaccination for optimal protection. If they were vaccinated in 2017-2018 influenza season or a prior season, 1 dose is recommended. People more than 8 years old require 1 dose of influenza vaccine. It is recommended that people receive their influenza vaccination by the end of October. Influenza vaccination should be offered as soon as the vaccination is available. For the people unable to be vaccinated before the end of October, influenza vaccination will continue to be offered for the whole season. Influenza vaccine is also recommended for use in pregnant women during any trimester. These guidelines are intended for use by staff members of the Centers for Disease Control and Prevention at all levels who work on influenza control and prevention, PoVs staff members, healthcare workers from the departments of pediatrics, internal medicine, and infectious diseases, and staff members of maternity and child care institutions at all levels.

Abstract
Objective: To explore the oncological safety of immediate breast reconstruction after nipple-areola complex(NAC) sparing mastectomy(NSM+ IBR) in patients with early stage breast cancer, and to analyze the prognostic factors of NSM+ IBR. Methods: From January 2004 to December 2015, the clinical data of 118 cases of stage Ⅰ-ⅡA breast cancer who had undergone NSM+ IBR in Tianjin Tumor Hospital were collected, comparing with 75 cases of Ⅰ-ⅡA breast cancer patients who had undergone immediate breast reconstruction after modified radical mastectomy (MRM+ IBR) at the same period. In addition to the prognosis of these two groups, the prognostic factors were also retrospectively analyzed. Results: The median follow-up were 53 months in the NSM+ IBR group and 51 months in the MRM+ IBR group, respectively. In the NSM+ IBR group, local recurrence, distant metastasis, death and NAC necrosis occurred in 4, 6, 9 and 4 cases during 3 years after operation, respectively. The local recurrence rate (LRR) was 3.4%, 3-year disease-free survival (DFS) rate was 91.5%, and the overall survival (OS) rate was 92.4%. In the MRM+ IBR group, local recurrence, distant metastasis, and death occurred in 1, 4, and 3 cases during 3 years after operation, respectively. The LRR was 1.3%, 3-year DFS was 93.3%, whereas the OS rate was 96.0%. No statistical difference was noted between the two groups (all P>0.05). That HER-2 positive and molecular type correlated with the 3-year DFS (P<0.05) independently and molecular type correlated with OS (P<0.05) independently in the NSM+ IBR group. Conclusions: NSM does not impair patients' prognosis and could ensure oncological safety of patients with early stage breast cancer. IBR could improve female patients' figure and ensure the quality of life. HER-2 status and molecular type are the independent prognostic factors of the 3-year DFS. Molecular type is the independent prognosis factor of OS.

Abstract
The European Male Aging Study (EMAS) has recently defined strict diagnostic criteria for late-onset hypogonadism (LOH) including the levels of serum total testosterone (TT), free testosterone (FT) and three sexual symptoms. However, there is no report on risk factors for LOH using these criteria. In this study, we investigated risk factors for LOH based on these criteria. We recruited 277 men (aged 36-80 years) who completed both a health check-up and two questionnaires (a health and lifestyle questionnaire, and a sexual function questionnaire). Data on parameters, such as systolic blood pressure (SBP), glucose, triglyceride (TG) and high-density lipoprotein (HDL), were obtained from medical records of the hospital in Shantou. TT and sex hormone-binding globulin (SHBG) were measured by chemiluminescent immunoassay, and FT was calculated. TT, FT, age, waist circumference, SBP and glucose showed significant differences between LOH-positive and LOH-negative individuals. Univariate regression analyses showed that age, waist circumference, SBP, glucose and health status were risk factors for LOH. Pearson's correlation analysis revealed that TT was inversely correlated with waist circumference, glucose and SBP, and FT was inversely correlated with age, SBP and health status. In conclusion, age, waist circumference, SBP, glucose and health status were risk factors for LOH.

Abstract
Objective: To investigate the effect of axillary lymph node status in evaluating the prognosis of patients with local recurrence after breast-conserving surgery. Methods: The clinical data of 72 patients with local-regional recurrence who had undergone breast-conserving therapy in Tianjin Cancer Hospital from February 2001 to December 2009 were collected and retrospectively analyzed. These patients were divided into axillary lymph node positive group (23 cases) and negative group (49 cases), according to their axillary lymph node status. Results: Among 72 patients, 21 cases were local recurrence, 35 cases were regional recurrence, and 16 cases were local-regional recurrence. In the axillary lymph node positive group, 7 cases were local recurrence, 10 cases were regional recurrence, 6 cases were local-regional recurrence. In the axillary lymph node negative group, 14 cases were local recurrence, 25 cases were regional recurrence, 10 cases were local-regional recurrence. There was no significant difference between these two groups (P=0.807). Moreover, no significant differences of the age, recurrent site, estrogen receptor (ER) and/or progesterone receptor (PR) status, human epidermal growth factor receptor 2 (HER-2) status, disease-free period, local and systemic therapeutic effect, non-distant metastasis survival between these two groups were observed (P>0.05). However, the overall survival of axillary lymph node positive group after recurrence was significantly lower than that of negative group (P=0.014). Cox multivariate analysis showed that recurrent site is an independent prognostic factor of disease-free survival of patients with regional recurrence after breast-conserving surgery (OR=2.050, P=0.002). The axillary lymph node status and recurrent site were independent prognostic factors of overall survival of these patients (OR=3.469, P=0.003; OR=3.676, P<0.001). Conclusions: Axillary lymph node status is an independent factor of overall survival of patients with regional recurrence after breast-conserving surgery, but it is marginally related with their non-distant metastasis survival.

Abstract
Objective: To analyze the spatial and temporal distributions of bacillary dysentery in Chongqing, Yichang and Enshi (the Three Gorges Area) from 2005 to 2016, and provide evidence for the disease prevention and control. Methods: The incidence data of bacillary dysentery in the Three Gorges Area during this period were collected from National Notifiable Infectious Disease Reporting System. The spatial-temporal scan statistic was conducted with software SaTScan 9.4 and bacillary dysentery clusters were visualized with software ArcGIS 10.3. Results: A total of 126 196 cases were reported in the Three Gorges Area during 2005-2016, with an average incidence rate of 29.67/100 000. The overall incidence was in a downward trend, with an average annual decline rate of 4.74%. Cases occurred all the year round but with an obvious seasonal increase between May and October. Among the reported cases, 44.71% (56 421/126 196) were children under 5-year-old, the cases in children outside child care settings accounted for 41.93% (52 918/126 196) of the total. The incidence rates in districts of Yuzhong, Dadukou, Jiangbei, Shapingba, Jiulongpo, Nanan, Yubei, Chengkou of Chongqing and districts of Xiling and Wujiagang of Yichang city of Hubei province were high, ranging from 60.20/100 000 to 114.81/100 000. Spatial-temporal scan statistic for the spatial and temporal distributions of bacillary dysentery during this period revealed that the temporal distribution was during May-October, and there were 12 class Ⅰ clusters, 35 class Ⅱ clusters, and 9 clusters without statistical significance in counties with high incidence. All the class Ⅰ clusters were in urban area of Chongqing (Yuzhong, Dadukou, Jiangbei, Shapingba, Jiulongpo, Nanan, Beibei, Yubei, Banan) and surrounding counties, and the class Ⅱ clusters transformed from concentrated distribution to scattered distribution. Conclusions: Temporal and spatial cluster of bacillary dysentery incidence existed in the three gorges area during 2005-2016. It is necessary to strengthen the bacillary dysentery prevention and control in urban areas of Chongqing and Yichang.

Abstract
This study aimed to examine the temporal (hourly within a day and daily over the long term) effects of monensin on CH4 emissions, ruminal fermentation, and in situ alfalfa degradation in dairy goats during dietary monensin supplementation by controlling the confounding effects of feed intake and ambient temperature. Six ruminally cannulated dairy goats were used, and they were housed in environmental chambers and fed a restricted amount of ration throughout the experiment. The experiment included a baseline period of 20 d followed by a treatment period of 55 d with 32 mg of monensin/d. During the whole experiment, CH4 production was measured every 5 d, whereas fermentation characteristics and in situ alfalfa degradation were analyzed every 10 d. The CH4-depressing effect of monensin was time dependent on the duration of treatment, highly effective at d 5 but thereafter decreased gradually until d 55 even though CH4-suppressing effect still remained significant. The decreasing effects of monensin on ruminal acetate proportion and acetate to propionate ratio also faded over days of treatment, and the acetate proportion returned up to the pre-supplementation level on d 50. Monensin supplementation elevated ruminal propionate proportion and decreased the effective ruminal degradability of alfalfa NDF, but both measurements tended to recover over time. The postprandial increase rate of hourly CH4 emissions was reduced, whereas that of propionate proportion was enhanced by monensin supplementation. However, the postprandial responses to monensin in CH4 emission rates, ruminal VFA profiles, and in situ degradation kinetics declined with both hours after feeding and days of treatment. Our results suggest that the CH4-suppressing effect of monensin supplementation in goats was attributed to reductions in both ruminal feed degradation and acetate to propionate ratio, but those reductions faded with time, hours after feeding, and days of treatment.
