Objective To explore the role of night waking in the cognitive development of infants and young toddlers. Method A total of 116 infants aged 2 to 30 months were randomly selected in Yiwu, Zhejiang from December 2011 to February 2013. Social-demographic factors were investigated through questionnaire;sleep information were collected via the Brief Infant Sleep Questionnaire (BISQ);Cognitive development was assessed in all infants using Baley development scale. Results The mean age was 12.99 month-old. 50.86%(59/116) were males. Ocassional night waking was reported in 5.26%, one night waking in 29.82%, multiple night waking accounted in 64.91%of children under one year old. Ocassional night waking was reported in 32.20%, one night waking in 45.76%, multiple night waking in 22.03%of children over one year old. The frequency of night waking was signiifcantly different between children under one year old and children over one year old (P<0.01). The average duration of waking was 0.49±0.31 h in children under one year old, and 0.31±0.48 h in children older than one year old, and the difference was signiifcantly different (Z=4.35, P<0.001). In children over one year old, the more frequent night waking, the lowered MDI scores (F=3.98, P=0.024). The waking duration was negatively correlated with MDI scores in children over one year old (r=-0.26, P=0.035). Neither night waking duration nor night waking frequency had signiifcant correlation with MDI scores in children under one year old. Multivariable linear regression conifrmed that night waking was an independent inlfuential factor of MDI and PDI scores in children over one year old. Conclusions Persistent night waking should warrant attention.

For the purpose of revealing the mechanism of the reduction of yeasts ethanol production rate after entrance of post-log phase, we used microarray to study expression profiles of the yeast Saccharomyces cerevisiae during the transition from mid-log growth phase to post-log growth. The results demonstrate that the global pattern of gene expression is very stable during the mid-log phase. However, a dramatic metabolic remodeling was found when the yeast entries post-log phase, during which many of amino acid synthesis and metabolism related genes are up-regulated, moreover, ion transport, energy generation and storage related genes are also up regulated during this phase, while a large number of genes involved in transposition and DNA recombination are repressed. Central metabolic pathways also engage in metabolic remodeling, within which the genes involved in succinate and a-ketoglutarate synthesis pathways are up regulated, accordance with those of amino acid synthesis and metabolism. These results demonstrate that the increasing demand for amino acids in post-log phase lead to a metabolic transition into TCA cycle and glyoxylate cycle, which subsequently reduce the ethanol production rate. This suggests a global insight into the process of yeast ethanol fermentation.

Objective To observe the changes of soluble triggering receptor expressed on myeloid cell-1 (sTREM-1)and inflammatory mediators in serum of senile patients with hospital-acquired pneumonia and explored the state of local inflammatory response in HAP. Methods Twenty senile patients with HAP and twenty healthy controls were in-cluded. Serum sTREM-1, nuclear factor-κB (NF-κB) and interleukin-8 (IL-8) were detected on day 1, 5, 10. Com-bined with CPIS score to analyze the correlation of these indicators and the severity and prognosis of pneumonia. Re-sults The concentrations of sTREM-1, NF-κB and IL-8 in serum were significantly higher than those in controls. There was a significant positive correlation between the sTREM-1, NF-κB and IL-8 and CPIS score. Conclusion sTREM-1, NF-κB and IL-8 is a good marker in diagnosing pneumonia. The levels of sTREM-1, NF-κB and IL-8 have a positive correlation with severity of HAP.

Objective:To investigate the prognosis of patients with initially resectable gastric cancer liver metastasis (GCLM) who were treated by different modalities, and analyze the influencing factors for prognosis of patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 327 patients with initially resectable GCLM who were included in the database of a nationwide multicenter retrospective cohort study on GCLM based on real-world data from January 2010 to December 2019 were collected. There were 267 males and 60 females, aged 61(54,68)years. According to the specific situations of patients, treatment modalities included radical surgery combined with systemic treatment, palliative surgery combined with systemic treatment, and systemic treatment alone. Observation indicators: (1) clinical characteristics of patients who were treated by different modalities; (2) prognostic outcomes of patients who were treated by different modalities; (3) analysis of influencing factors for prognosis of patients with initially resectable GCLM; (4) screening of potential beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. The propensity score matching was employed by the 1:1 nearest neighbor matching method with a caliper value of 0.1. The forest plots were utilized to evaluate potential benefits of diverse surgical combined with systemic treatments within the population. Results:(1) Clinical characteristics of patients who were treated by different modalities. Of 327 patients, there were 118 cases undergoing radical surgery plus systemic treatment, 164 cases undergoing palliative surgery plus systemic treatment, and 45 cases undergoing systemic treatment alone. There were significant differences in smoking, drinking, site of primary gastric tumor, diameter of primary gastric tumor, site of liver metastasis, and metastatic interval among the three groups of patients ( P<0.05). (2) Prognostic outcomes of patients who were treated by different modalities. The median overall survival time of the 327 pati-ents was 19.9 months (95% confidence interval as 14.9-24.9 months), with 1-, 3-year overall survival rate of 61.3%, 32.7%, respectively. The 1-year overall survival rates of patients undergoing radical surgery plus systemic treatment, palliative surgery plus systemic treatment and systemic treatment alone were 68.3%, 63.1%, 30.6%, and the 3-year overall survival rates were 41.1%, 29.9%, 11.9%, showing a significant difference in overall survival rate among the three groups of patients ( χ2=19.46, P<0.05). Results of further analysis showed that there was a significant difference in overall survival rate between patients undergoing radical surgery plus systemic treatment and patients undergoing systemic treatment alone ( hazard ratio=0.40, 95% confidence interval as 0.26-0.61, P<0.05), between patients undergoing palliative surgery plus systemic treatment and patients under-going systemic treatment alone ( hazard ratio=0.47, 95% confidence interval as 0.32-0.71, P<0.05). (3) Analysis of influencing factors for prognosis of patients with initially resectable GCLM. Results of multivariate analysis showed that the larger primary gastric tumor, poorly differentiated tumor, larger liver metastasis, multiple hepatic metastases were independent risk factors for prognosis of patients with initially resectable GCLM ( hazard ratio=1.20, 1.70, 1.20, 2.06, 95% confidence interval as 1.14-1.27, 1.25-2.31, 1.04-1.42, 1.45-2.92, P<0.05) and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy were independent protective factors for prognosis of patients with initially resectable GCLM ( hazard ratio=0.60, 0.39, 0.46, 95% confidence interval as 0.42-0.87, 0.25-0.60, 0.30-0.70, P<0.05). (4) Screening of potentinal beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Results of forest plots analysis showed that for patients with high-moderate differentiated GCLM and patients with liver metastasis located in the left liver, the overall survival rate of patients undergoing radical surgery plus systemic treatment was better than patients undergoing palliative surgery plus systemic treatment ( hazard ratio=0.21, 0.42, 95% confidence interval as 0.09-0.48, 0.23-0.78, P<0.05). Conclusions:Compared to systemic therapy alone, both radical and palliative surgery plus systemic therapy can improve the pro-gnosis of patients with initially resectable GCLM. The larger primary gastric tumor, poorly differen-tiated tumor, larger liver metastasis, multiple hepatic metastases are independent risk factors for prognosis of patients with initial resectable GCLM and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy are independent protective factors for prognosis of patients with initially resectable GCLM.
