Abstract
OBJECTIVE Anxiety is a prevalent comorbidity in lung cancer (LC) patients associated with a decline in quality of life. Dehydroepiandrosterone (DHEA), a neuroactive steroid, levels rise in response to stress. Prior research on the association between DHEA and anxiety has yielded contradictory results and no study has investigated this association in LC patients. METHODS A total of 213 patients with LC were recruited from a general hospital. Data on demographic and cancer-related variables were collected. Using the Chinese version of the Hospital Anxiety and Depression Scale (HADS), the degree of anxiety was determined. Cortisol, DHEA, and Dehydroepiandrosterone sulfate (DHEA-S) levels in saliva were measured. Adjusting for confounding variables, a multivariate regression analysis was conducted. RESULTS 147 men and 66 women comprised our group with an average age of 63.75 years. After accounting for demographic and treatment-related factors, anxiety levels were significantly correlated with, post-traumatic stress symptoms (PTSSs) (β = 0.332, p < 0.001) and fatigue (β = 0.247, p = 0.02). Association between anxiety and three factors, including DHEA, PTSSs, and fatigue, was observed in patients with advanced cancer stages (III and IV) (DHEA β = 0.319, p = 0.004; PTSS β = 0.396, p = 0.001; fatigue β = 0.289, p = 0.027) and those undergoing chemotherapy (DHEA β = 0.346, p = 0.001; PTSS β = 0.407, p = 0.001; fatigue β = 0.326, p = 0.011). CONCLUSIONS The association between anxiety and DHEA remained positive in advanced cancer stages and chemotherapy patients. Further study is necessary to determine whether DHEA is a potential biomarker of anxiety in LC patients.

Abstract
BACKGROUND Positive fluid balance and tissue fluid accumulation are associated with adverse outcomes in sepsis. Vascular endothelial growth factor (VEGF) increases in sepsis, promotes vascular permeability, and may affect tissue fluid accumulation and oxygenation. We used near-infrared spectroscopy (NIRS) to estimate tissue hemoglobin (Hb) oxygenation and water (H2O) levels to investigate their relationship with serum VEGF levels. MATERIAL AND METHODS New-onset severe sepsis patients admitted to the intensive care unit were enrolled. Relative tissue concentrations of oxy-Hb ([HbO2]), deoxy-Hb ([HbR]), total Hb ([HbT]), and H2O ([H2O]) were estimated by near-infrared spectroscopy (NIRS) for three consecutive days and serum VEGF levels were measured. Comparisons between oliguric and non-oliguric patients were conducted and the correlations between variables were analyzed. RESULTS Among 75 eligible patients, compared with non-oliguric patients, oliguric patients were administrated more intravascular fluids (median [IQR], 1926.00 [1348.50-3092.00] mL/day vs. 1069.00 [722.00-1486.75] mL/day, p < 0.001) and had more positive daily net intake and output (mean [SD], 1,235.06 [1303.14] mL/day vs. 313.17 [744.75] mL/day, p = 0.012), lower [HbO2] and [HbT] over the three-day measurement (analyzed by GEE p = 0.01 and 0.043, respectively) and significantly higher [H2O] on the third day than on the first two days (analyzed by GEE p = 0.034 and 0.018, respectively). Overall, serum VEGF levels were significantly negatively correlated with [HbO2] and [HbT] (rho = - 0.246 and - 0.266, p = 0.042 and 0.027, respectively) but positively correlated with [H2O] (rho = 0.449, p < 0.001). Subgroup analysis revealed a significant correlation between serum VEGF and [H2O] in oliguric patients (rho = 0.532, p = 0.003). Multiple regression analysis determined the independent effect of serum VEGF on [H2O] (standardized coefficient = 0.281, p = 0.038). CONCLUSIONS In severe sepsis, oliguria relates to higher positive fluid balance, lower tissue perfusion and oxygenation, and progressive tissue fluid accumulation. Elevated serum VEGF is associated with worsening tissue perfusion and oxygenation and independently affects tissue fluid accumulation.

Abstract
A proton (H+) and zinc ion (Zn2+) co-insertion model is put forward in this study to elucidate the capacity origin of an aqueous zinc ion battery (ZIB) based on a heavily loaded (∼15 mg cm-2) cathode, which consists of Na2V6O16·3H2O (NVO) embedded particularly in the macropores of activated carbon cloth (ACC), coupled with a highly stable Zn/In anode. The confinement effect of these porous channels not only prevents the detachment of NVO from ACC but also well mitigates its volume change resulting from H+ and Zn2+ co-intercalation, which collectively render the stability of NVO/ACC markedly enhanced. Moreover, the bicontinuous structure of NVO/ACC, as a result of the self-interlacing of intrapore NVO, which is first engineered into the nanobelts, and their interlocking with the carbon fibers of ACC, simultaneously giving rise to a solid and a holey framework, is favorable to the electron and ion transport throughout the entire electrode. The synergistic effect of such facile charge transfer kinetics and the high packing density of NVO in the cathode endows ZIBs with not only a good rate performance but also an exceptional areal capacity amounting to 4.6 mAh cm-2, far surpassing those reported for additional vanadium-based counterparts reported in the literature.

Abstract
Objective: To estimate the risk for type 2 diabetes mellitus (T2DM) death attributed to insufficient whole grain intake in seven regions of China from 2005 to 2018. Methods: Based on China National Nutrition and Health Surveys and China Adult Chronic Disease and Nutrition Surveillance, ordinary Kriging method and locally weighted regression were used to estimate the level of whole grain intake of Chinese residents from 2005 to 2018. Based on the results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 and Chronic Diseases Risk Factors Surveillance in China, we calculated the population attributable fraction (PAF), attributable death number and attributable mortality rate of T2DM due to insufficient whole grain intake in people aged ≥20 years in different regions of China, and we used the 2010 Chinese census data to compare the changes in T2DM deaths attributed to insufficient intake of whole grains in seven regions of China. Results: The whole grain intake levels of Chinese people over 20 years old in 2002, 2010 and 2015 were 19.0 g/d, 14.3 g/d and 19.8 g/d, respectively. The estimated overall whole grain intake level was 20.1 g/d in Chinese residents in 2018, and the intake level was 19.4 g/d in men and 20.8 g/d in women. Among the seven regions, the intake level was highest in northern China (47.4 g/d) and lowest in southwestern China (6.0 g/d). In 2018, the PAF was lowest in northern China (12.8%) and highest in southwestern China (19.3%). From 2005 to 2018, the PAF varied in the seven regions, and the PAF in northeastern China fluctuated around 18.5%. Other regions showed downward trends, especially in northern China and northwestern China, decreased by 26.4% and 21.2%, respectively. Over the past 14 years, the number of attributable deaths in the seven regions showed upward trends, with the highest annual average growth rate of 6.7% in southern China and the lowest annual average growth rate of 2.4% in northern China. In 2018, the standardized T2DM mortality rate attributed to insufficient whole grain intake in China was 3.13/100 000, and the attributable mortality was 3.21/100 000 in men and 3.05/100 000 in women. The standardized attributable mortality rate was highest in southwestern China (3.97/100 000) and lowest in northern China (1.78/100 000). From 2005 to 2018, the standardized attributable mortality rate increased by 11.5% in men and decreased by 8.1% in women. The standardized attributable mortality rate in southwestern, southern and central China increased by 23.7%, 21.3% and 4.2%, respectively. The standardized attributable mortality rate in northern, northwestern, eastern and northeastern China decreased by 20.9%, 11.0%, 4.5% and 3.9%, respectively. Conclusion: The whole grain intake level of Chinese residents was low, and the whole grain intake of residents in all seven regions should be increased, especially in the southwest, and men should have more whole grain intake than women to reduce the death risk in patients with T2DM.

Abstract
Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

Abstract
Objective: To investigate the incidence, risk factors, and outcomes of hyperlactatemia after pulmonary endarterectomy (PEA) under deep hypothermic circulatory arrest (DHCA). Methods: From December 2016 to January 2022, patients receiving PEA in China-Japan Friendship Hospital were enrolled in the study. Arterial blood samples were analyzed intraoperatively. Multivariate logistic regression analysis was performed to identify the predictors of intraoperative lactate elevation as well as major factors influencing the clinical outcome of the surgery. Results: A total of 110 patients (69 males and 41 females) were enrolled, aged (50.6±12.8) years. Receiver operating characteristic curve yielded an optimal cut-off lactate level of 7 mmol/L for predicting major postoperative complications (re-operation, re-intubation, postoperative renal failure requiring renal replacement therapy, wound infection, stroke, atrial fibrillation, and perioperative extracorporeal membrane oxygenation usage within 48 hours after surgery). Thirty-nine patients (35.5%) had an intraoperative peak arterial lactate level of≥7 mmol/L. According to intraoperative peak arterial lactate level, the patients were divided into two groups (<7 mmol/L and≥7 mmol/L). There were no statistically significant differences in age, sex and body mass index between the two groups (all P>0.05). Intraoperative peak lactate level was associated with prolonged mechanical ventilation time (r=0.262, P=0.008) and intensive care unit length of stay (r=0.304, P=0.002). Multivariate logistic regression analysis identified three key variables associated with lactate level≥7 mmol/L: DHCA duration (OR=1.186, 95%CI: 1.027-1.370, P=0.020), nadir hematocrit (HCT) (OR=0.580, 95%CI: 0.341-0.988, P=0.045) and preoperative pulmonary vascular resistance (PVR) (OR=1.096, 95%CI: 1.020-1.177, P=0.012). Patients with lactate≥7 mmol/L carried a higher rate of major complications (P=0.001). For patients with lactate≥7 mmol/L, 41.0% (16 out of 39 cases) had major complications, while for patients with lactate<7 mmol/L, only 14.1% (10 out of 71) had major complications. There was no statistically significant difference in mortality (8.5% vs 10.3%, P=0.753) between patients with different lactate levels. Moreover, intraoperative peak lactate level was a predictor of postoperative combined morbidity (OR=1.625, 95%CI: 1.176-2.245, P=0.003). Conclusion: High intraoperative lactate levels are associated with higher preoperative PVR, lower nadir HCT, and longer DHCA duration. Intraoperative lactate levels are independently associated with increased combined morbidity.

Abstract
Purpose Previous retrospective studies reported that proton-pump inhibitors (PPIs) may decrease the efficacy of first-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) including gefitinib and erlotinib. Afatinib had a wider soluble pH range, with possible fewer interactions with antacids. However, clinical data were limited. Thus, this study aimed to evaluate the negative impact of PPIs on afatinib. Patients and Methods This retrospective cohort study included patients who are newly diagnosed with non-small cell lung cancer (NSCLC) from 2014 to 2019 using the Chang Gung Research Database. We identified patients who were treated with first-line afatinib and analyzed the association between the PPI and afatinib treatment outcomes. Results A total of 1418 patients were treated with first-line afatinib and followed up for 6 years. First-line afatinib was administered to 918 eligible patients, and 330 had afatinib with PPIs. The combination use of PPIs and afatinib significantly decreased the overall survival (OS) compared with that of patients using afatinib only (median OS: 33.2 and 25.1 months, p < 0.01) and multivariate analyses (Combination use: hazard ratio: 1.29; 1.05-1.59, p = 0.01). The percentages of patients who were able to receive 2nd line therapy also significantly decreased in afatinib with PPI cohort. Conclusion The concurrent use of PPIs was associated with lower OS in patients with EGFR-mutant lung cancer under the first-line afatinib treatment but not associated with TTF.

Abstract
Aim Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKIs)-associated Clostridioides difficile infection (CDI) among lung cancer patients have been reported in case reports and adverse events reporting system databases in the United States and Japan, but clinical data remained insufficient. This study aims to evaluate CDI in lung cancer patients receiving EGFR-TKIs. Methods We conducted a retrospective cohort study using multi-institutional electronic medical records database. We included patients aged older than 20 years diagnosed with lung cancer and treated with EGFR-TKIs (gefitinib, erlotinib, afatinib). We defined EGFR-TKI initiation date as the index date and occurrence of diarrhea with CDI or without CDI as the event date. We followed patients from the index date until the event date, ICU admission, death, or 12/31/2019. Results We included 2242 diarrhea patients, 51 were EGFR-TKI with CDI cohort, and 2191 were diarrhea without CDI cohort. Patients who were concurrently taking antibiotics (hazard ratio [HR], 3.30; 95% CI, 1.67-6.5) and systemic steroids (HR, 4.9; 95% CI, 2.65-9.06) had an increased risk of CDI. First-generation EGFR-TKIs tended to be associated with an increased risk of CDI compared with afatinib (HR, 1.81, 95% CI, 0.94-3.47). EGFR-TKI with CDI had a higher ICU admission rate (HR, 3.42, 95% CI, 1.98-5.91) and mortality rate (HR, 2.34, 95% CI, 1.67-3.28) than diarrhea without CDI. Conclusion Patients with CDI had higher ICU admission rates and mortality rates than those without CDI. Concurrent use of antibiotics and systemic steroids were risk factors for CDI among patients with lung cancer receiving EGFR-TKIs. Afatinib was not associated with a higher risk of CDI than first-generation EGFR-TKIs.

Abstract
PURPOSES This study investigated the prevalence and clinical outcomes of pulmonary bacterial co-infections and secondary bacterial infections in patients with severe influenza pneumonitis. METHODS We retrospectively analyzed the data of adult patients with severe influenza pneumonitis admitted to medical ICUs. Bacterial co-infections and secondary bacterial infections were identified. The risk factors of bacterial infection were evaluated. The outcomes of patients regarding co-infection or secondary bacterial infection were analyzed. RESULTS We identified 117 critically ill patients with laboratory-confirmed influenza pneumonitis admitted to the medical ICUs. Klebsiella pneumoniae (31.4%) and Staphylococcus aureus (22.8%) were the most identified bacteria in patients with bacterial co-infection. A high proportion of methicillin-resistant Staphylococcus aureus (17.1%) was noted. Liver cirrhosis and diabetes mellitus were the independent risk factors for bacterial co-infection. Acinetobacter baumannii (30.7%) and S. aureus (23.1%) were the most often identified bacteria in patients with secondary bacterial pneumonia. Patients with secondary bacterial infections had a longer duration of mechanical ventilation, and longer ICU and hospital stay. CONCLUSIONS High rates of drug-resistant bacterial co-infections and secondary bacterial infections were identified in patients with severe influenza pneumonitis requiring ICU care and were associated with more morbidity in these patients.

Abstract
Objective: To explore the incidence and the risk factors of post-polypectomy bleeding and polyp recurrence after colonoscopic high-frequency electrocoagulation snare polypectomy. Methods: Clinical data of 1 826 children who underwent colonoscopic high-frequency electrocoagulation snare polypectomy in the Children's Hospital, Zhejiang University School of Medicine from January 2009 to December 2020 was retrospectively analyzed. Demographic characteristics, endoscopic manifestations, pathological features, diagnosis, occurrence of post-polypectomy bleeding and polyp recurrence were collected. The associated risk factors were analyzed by Logistic regression. Results: A total of 1 826 children (1 191 males and 635 females) with 1 967 polypectomies were included. The age was 4.6 (3.2, 6.4) years at initial diagnosis. According to the initial colonoscopy, 1 611 children (88.2%) had solitary polyps, 1 707 children (93.5%) had pedicled polyps, 1 151 children (63.0%) had polyps involving the rectum, and 1 757 children (96.2%) had hamartomatous polyps. Polyposis syndromes were diagnosed in 73 children (4.0%). The post-polypectomy bleeding occurrence was 3.8% (75/1 967). Polyps recurred in 88 children (4.8%). Girls (OR=2.01, 95%CI 1.26-3.23) and sessile polyps (OR=2.28, 95%CI 1.15-4.49) were risk factors for post-polypectomy bleeding (both P<0.05). Multiple polyps (OR=17.49, 95%CI 9.82-31.18), right-colon involvement (OR=3.44, 95%CI 1.89-6.26) and non-hamartoma (OR=2.51, 95%CI 1.04-6.07) were risk factors for polyp recurrence (all P<0.05). Conclusions: Colonoscopic high-frequency electrocoagulation snare polypectomy has low incidence of post-polypectomy bleeding and polyp recurrence. Female patients and sessile polyps have higher risk for post-polypectomy bleeding. Multiple polyps, right-colon involvement and non-hamartoma polyps increase the risk for polyp recurrence.

Abstract
ROS1 fusion genes are rare but important driver genes in lung cancer. Owing to their rarity, many clinicopathological features and treatment responses for each ROS1 fusion variant are still largely unknown and require further investigation. RNA is the preferable template for the ROS1 fusion gene screening, but deterioration of RNA in FFPE often makes the detection challenging. To resolve the difficulty, a targeted chromosomal breakpoint sequencing method was developed for searching the ROS1 fusion gene, and was compared with fluorescence in situ hybridization, immunohistochemistry, RT-qPCR using 260 lung cancer samples of Southern Taiwan. The results showed that ROS1-altered cases were present at low frequencies, did not share distinct clinicopathological features, and often carried other driver mutations. The performance of the targeted sequencing assay was superior to the RT-qPCR in ROS1 fusion gene identification when the cDNAs were from FFPE samples, but long-read DNA sequencing and fresh-frozen samples would be better to revolve all fusion genes. Precise determination of all ROS1 fusion variants and concomitant driver mutations using both genomic DNA and RNA would be required to help improve the treatment of patients with ROS1 alterations.

Abstract
Background Sleep disturbances are common and symptomatic burden in patients with breast cancer, but they are poorly documented and managed in routine clinical practice. This descriptive and cross-sectional study evaluated factors associated with post-treatment sleep disturbances in patients with breast cancer. Patients and Methods Patients with breast cancer who underwent standard treatment were enrolled and surveyed for their basic demographic data and precancerous and cancer treatment-related factors; they were also administered self-report questionnaires including the Family Adaptation, Partnership, Growth, Affection, Resolve questionnaire; Impact of Event Scale; Center for Epidemiologic Studies Depression Scale; and Maudsley Personality Inventory. Their sleep disturbances were evaluated using the Pittsburgh sleep quality index (PSQI). Independent sample t test and chi-square tests were used to compare the variables between patients with or without sleep disturbance, and multivariate logistic regression analyses were conducted to detect the independent factors. Results In total, 448 patients, including 145 with PSQI ≤ 5 and 303 with PSQI > 5, completed the investigation. Multiple logistic regression analysis revealed that significantly more patients with sleep disturbances demonstrated psychological distress, severe pain, depression, and impact of stress events than patients without sleep disturbances (adjusted odds ratios [95% confidence intervals]: 2.83 [1.135–7.067], P = 0.026; 1.14 [1.023–1.280], P = 0.018; 1.08 [1.036–1.133], P < 0.001; and 1.03 [1.002–1.051], P = 0.037, respectively). Conclusion Patients with breast cancer showed 67.6% prevalence of sleep disturbances after treatment. The patients with sleep disturbances were more likely to have previously experienced psychological disturbances, severe pain, depression within 5 years after diagnosis. After diagnosis for more than 5 years, higher distress caused by traumatic events still associated with sleep disturbances.

Abstract
OBJECTIVE Data regarding the prevalence of depression and anxiety among cancer patients, especially before cancer diagnosis, remains scarce. This study investigated the prevalence of these conditions and associated drug use among cancer patients pre- and post-diagnosis. METHODS This population-based cohort study using data from Taiwan's National Health Insurance Research Database recruited patients with a registered cancer diagnosis and matched control between January 1, 2000, and December 31, 2011. We compared the prevalence of anxiety and depressive disorders between cancer patients and non-cancer participants during a 2-year period both pre- and post-diagnosis by Pearson's chi-square test. Psychiatric medication use was also examined for the associated mental condition. RESULTS We examined participants diagnosed with liver (N = 17,154), colorectal (N = 30,391), breast (N = 40,036), gynecological (N = 23,218), and lung (N = 15,671) cancer. Before the cancer diagnosis, the prevalence of depression was higher in non-cancer participants than in gynecological cancer patients (p = 0.018) but anxiety is higher in liver, colorectal, and lung cancer patients when compared to non-cancer participants (p < 0.05). After the cancer diagnosis, the prevalence of anxiety and depression became significantly higher in all enrolled cancer patients than non-cancer participants (p < 0.05). Similar results were observed in psychiatric medication use trends. CONCLUSIONS This study proposed that patients with liver, colorectal, and lung cancer had an increased risk of developing anxiety, which might be a sentinel diagnosis. The participants had a significantly higher level of anxiety and depressive disorder post-diagnosis, which highlights the importance of the care for both mental and physical conditions in cancer management.

Abstract
Mutations that lead to constitutive activation of key regulators in cellular processes are one of the most important drivers behind vigorous growth of cancer cells, and are thus prime targets in cancer treatment. BRAF V600E mutation transduces strong growth and survival signals for cancer cells, and is widely present in various types of cancers including lung cancer. A combination of BRAF inhibitor (dabrafenib) and MEK inhibitor (trametinib) has recently been approved and significantly improved the survival of patients with advanced NSCLC harboring BRAF V600E/K mutation. To improve the detection of BRAF V600E/K mutation and investigate the incidence and clinicopathological features of the mutation in lung cancer patients of southern Taiwan, a highly sensitive and specific real-time quantitative PCR (RT-qPCR) method, able to detect single-digit copies of mutant DNA, was established and compared with BRAF V600E-specific immunohistochemistry. Results showed that the BRAF V600E mutation was present at low frequency (0.65%, 2/306) in the studied patient group, and the detection sensitivity and specificity of the new RT-qPCR and V600E-specific immunohistochemistry both reached 100% and 97.6%, respectively. Screening the BRAF V600E/K mutation with the RT-qPCR and V600E-specific immunohistochemistry simultaneously could help improve detection accuracy.

Abstract
Objective: To establish Chinese diet balance index for preschool children(DBI_C), and evaluate the dietary quality of Chinese preschool children. Methods: DBI_C was established according to the methods establishing DBI_16 and the recommended intake of different kinds of food for preschool children. Three scoring methods [low bound score (LBS), high bound score (HBS), diet quality distance (DQD)] were used to evaluate the dietary quality of preschool children selected from the 2010-2012 China National Nutrition and Health Surveillance. Scores [P50(P25, P75)] were compared to reflect the diet quality of preschool children in different regions. Results: DBI_C scores for cereals of preschool children from big city, middle and small city, normal rural area, and poor rural area were 0.0 (-2.0, 6.0), 0.0 (0.0, 6.0), 4.0 (0.0, 10.0), and 10.0 (2.0, 12.0), respectively (P<0.001), indicating that the intakes of cereals of preschool children were adequate. Scores for animal food of preschool children from four types of location were 0.0 (-2.0, 2.0), 0.0 (-6.0, 2.0), -4.0 (-6.0, 0.0), and -6.0 (-8.0,-2.0), respectively (P<0.001), indicating that the intakes of animal food of rural preschool children were inadequate. Scores for vegetable and fruit, milk and soybean were both less than 0 (P<0.001), indicating that the intakes of these food were insufficient in both urban and rural area. Scores of LBS, HBS and DQD were 24.0 (18.0, 30.0), 8.0 (3.0, 13.0) and 33.0(26.0, 39.0). Children without diet insufficient problem in four type of location accounted for 30.8%, 7.8%, 4.3% and 1.1%, respectively (P<0.001). Children without diet excessive problem accounted for 54.0%, 57.3%, 52.9% and 32.6%, respectively (P<0.001). Children without diet imbalance problem were 10.6%, 1.1%, 1.3% and 0.3%, respectively (P<0.001). Conclusion: Diet quality of urban preschool children is better than that of rural preschool children. Dietary imbalance is the main problem among Chinese preschool children.

Abstract
BACKGROUND Dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS) concentrations were reported to decrease in patients with advanced cancer. However, the clinical significance of DHEA and DHEAS concentrations in patients with NSCLC receiving chemotherapy (CT) has not been sufficiently documented. OBJECTIVE To evaluate the correlation between mental health and hormone concentrations on patients with advanced non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS The present study was a cross-sectional analysis based on a self-reported psychological investigation. Salivary samples were collected from 22 patients with advanced NSCLC after CT and 17 healthy controls. The concentrations of DHEA, DHEAS, and cortisol were analyzed to investigate their associations with the results of self-reported questionnaires on psychological health. RESULTS Patients with advanced NSCLC exhibited significantly higher Patient Health Questionnaire (PHQ-9) and Startle, Physiological arousal, Anger, and Numbness-Chinese version (SPAN-C) scores, poorer health conditions, lower sleep quality, and more severe fatigue after CT than did healthy controls, and salivary concentrations of DHEA and DHEAS were significantly lower among patients after CT than among controls. DHEAS concentrations were negatively associated with depression scores (PHQ-9, r = -0.496, P = 0.019) and fatigue scores (Brief Fatigue Inventory-Taiwan, r = -0.562, P = 0.006). CONCLUSION Patients with advanced NSCLC after CT had lower DHEA and DHEAS concentrations than did controls. Lower DHEAS concentrations were associated with higher fatigue and depression scores.

Abstract
Purpose Concurrent proton pump inhibitor (PPI) use might reduce the plasma concentration of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs). Clinically, the adverse effect of PPIs on patients with non-small cell lung cancer (NSCLC) treated with first-line EGFR TKIs remains controversial. This study was conducted to evaluate whether the combined use of gefitinib with PPIs affected NSCLC outcomes. Patients and methods We performed a nationwide cohort study of patients newly diagnosed with NSCLC between 1997 and 2013 using the Taiwan Cancer Registry and Taiwan National Health Insurance databases. We identified patients who were treated with first-line EGFR TKIs and analyzed the association between use of PPIs and TKI treatment outcome. We defined the coverage ratio of PPIs as duration of PPI treatment in days divided by duration of TKIs in days. Patients who exhibited an overlap of >20% between PPI and TKI usage days were defined as having a high coverage ratio. Results A total of 1278 patients were treated with first-line gefitinib, 309 of which took PPIs at the same time and 145 had a high PPI coverage ratio. Patients had similar time to failure regardless of their PPI coverage ratio during gefitinib treatment. However, higher PPI coverage ratio significantly decreased overall survival (OS) compared with that of patients with a lower PPI coverage ratio or no PPI treatment in univariate analysis (median OS, 13.5, 16.7, and 21.8 months, respectively, p<0.01) and multivariate analyses (high coverage ratio HR: 1.67; low coverage ratio HR: 1.29). Exposure to PPIs during first line gefitinib treatment significantly decreased overall survival of patients with NSCLC. Conclusion Concurrent use of PPIs was associated with lower overall survival in patients with EGFR-mutant NSCLC under first-line gefitinib treatment.

Abstract
Somatic mutations of MET gene are emerging as important driver mutations for lung cancers. To identify the common clinicopathological features of MET exon 14 skipping mutations and amplification and clarify whether the two MET gene alterations cause protein overexpression were investigated using 196 lung cancer samples of Taiwan through real time-qPCR/sequencing, fluorescence in situ hybridization, and immunohistochemistry. The two MET gene alterations are both present in low frequency, ~1%, in the studied lung cancer population of Taiwan. MET exon 14 skipping mutations were identified from two early-stage patients, who were both relatively advanced in age, and did not carry other driver mutations. One was an adenocarcinoma and the other was a rare carcinosarcoma. Three gene amplifications cases were identified. Neither of the two MET gene alterations would lead to protein overexpression; hence, direct detection in nucleic acid level would be a preferred and straightforward solution for the identification of skipping mutations. The presence of MET exon 14 mutations in minor histological types of lung cancers urge to extend screening scope of this mutation in lung cancer and treatment response evaluation in clinical trials. These would be important next steps for the success of MET target therapy in clinical practice.

Abstract
Objective: To investigate the incidence of asymptomatic sinusitis in children by magnetic resonance imaging. Method: Collected the head MRI of 1-12 years old children. According to the examination site,the MRI group and the pituitary MRI group (both sinus level) were included.The nasal-sinusitis-like changes in the field were used as positive criteria. Statistical analysis was conducted on the test results. Result: In 3 900 children with MRI, the positive rate of sinusitis was 30.21%. The positive rate increased from 2 years old to 3 years old and remained at the age of 11 years.The higher positive rate was slightly decreased at 12 years old; 1 228 cases of pituitary MRI examination, the positive rate of nasal-sinusitis was 38.27%, the positive rate increased significantly from the age of 2, reached the peak at 6 years old, and then fell back, still kept high positive rate, the lowest to 12 years old. The positive rate of total sinusitis was 32.14%. No obvious difference was found between two groups. Conclusion: Children's skull and pituitary MRI imaging suggests that the positive rate of nasal-innocuous sinusitis is related to age, peaking at 3 to 8 years old, and then gradually decreasing.

Abstract
Objective: To explore the clinical features and complications of foreign bodies in the upper gastrointestinal tract in children and to investigate the effectiveness of endoscopic management. Methods: Data of patients with foreign bodies in upper gastrointestinal tract were collected retrospectively at Endoscopy Center, the Children's Hospital, Zhejiang University School of Medicine, from January 2011 to December 2016. Clinical characteristics, the types of foreign bodies, the location and duration of foreign body impaction were summarized. The risk factors of complications and endoscopic removal failure were analyzed by using Logistic regression analysis. Results: A total of 1 334 patients (825 males and 509 females) were enrolled. The median age was 2.5 years, with a range from 0.25 to 15 years and peak age 1-3 years. Twenty patients had esophageal diseases. The most common foreign body ingested was coin (n=964, 72.3%). Foreign bodies were most commonly located in the esophagus (n=1 002, 75.1%), especially in the upper esophagus (n=857, 85.5%). The duration of foreign body impaction ranged from 3 hours to 5 years. Among 1 334 patients, 252 patients (18.9%) developed complications, including ulcers (n=101, 40.0%) and perforations(n=13, 5.2%). The success rate of endoscopic removal was 96.6% (n=1 288). By Logistic regression analysis, sharp foreign body ingestion (OR=6.893, 95%CI: 4.421-10.746) , esophageal impaction (OR=5.253, 95%CI:3.352-8.233) and foreign body impaction longer than 24 hours (OR=4.336, 95%CI:3.091-6.082) were risk factors of complications. Sharp foreign body ingestion was the risk factor of endoscopic failure (OR=5.372, 95%CI:2.773-10.406) . Conclusions: Coin is the most common foreign body in upper gastrointestinal tract. Sharp foreign bodies impacted in the esophagus over 24 hours increase the risk of complications. Endoscopic removal of foreign bodies from the upper gastrointestinal tract in children has a high success rate. Sharp foreign body ingestion increases the risk of failure in endoscopic removing.

Abstract
Objective: To understand the prevalence of alcohol drinking and influencing factors in female adults in China. Methods: At the 150 survey sites where 2010-2012 Chinese nutrition and health surveillance was conducted, a face to face questionnaire survey was conducted in female adults selected through multi-stage stratified cluster random sampling. Sample weights was assigned to each participant based on the study design by using national population census data in 2009. The complex sampling and unconditional multivariate logistics regression analysis was conducted to identify the influencing factors for the prevalence of alcohol drinking in the female adults. Results: A total of 75 518 participants were included in this study. The prevalence of drinking in female adults was 13.9% (95%CI: 11.7-16.2) in urban area and 13.3% (95%CI: 9.4-17.2) in rural area. The prevalence of frequent drinking was 13.9% (95%CI: 9.9-17.9) in women in urban area and 14.2% (95%CI: 10.8-17.6) in women in rural area. The prevalence of excessive drinking was 11.1% (95%CI: 7.5-14.8) in women in urban area and 12.8% (95%CI: 9.1-16.4) in women in rural area. The prevalence of wine drinking in women in urban area was significantly higher than in women in rural and had positive correlation with income and education levels. The social and economic factors influencing drinking behavior of the female adults included occupation, drinking behaviors of family members and smoking behavior. Those who were engaged in agriculture, production and transportation (OR=0.72, 95%CI: 0.56-0.94, P=0.016), housework (OR=0.59, 95%CI: 0.44-0.78, P<0.001) and other work (OR=0.61, 95%CI: 0.43-0.85, P=0.004) had lower drinking prevalence. Whereas those whose family members had drinking behavior (OR=2.66, 95%CI: 2.17-3.26, P<0.001) and those who were current smokers (OR=4.32, 95%CI: 2.95-6.34, P<0.01) had higher drinking prevalence. Conclusions: The prevalence of drinking, frequent alcohol drinking and excessive drinking were relatively low in female adults in China. Occupation, drinking behaviors of family members and smoking behavior were the main factors influencing the prevalence drinking behavior in female adults in China.

Abstract
Objective: To explore the effects of N-(4-hydroxyphenyl) retinamide (4HPR), 4HPR liposome (4HPR-L), and 4HPR lipid microbubble (4HPR-LM) combined with ultrasound on proliferation, apoptosis, and cell cycle of human keloid fibroblasts (Fbs). Methods: (1) 4HPR-L and 4HPR-LM were prepared by hydration ultrasonic method. The appearance morphology, particle size distribution, Zeta potential, loading drug concentration, encapsulation efficiency, and drug loading rate of 4HPR-L were investigated by high performance liquid chromatography, dynamic light scattering, and transmission electron microscope. (2) Human keloid Fbs were cultured and divided into 13 groups by random number table (the same grouping method below), with 6 wells in each group. Cells in control group were given no treatment, while cells in 12 ultrasound groups including 0.5 W 30 s group, 0.5 W 60 s group, 0.5 W 120 s group, 0.7 W 30 s group, 0.7 W 60 s group, 0.7 W 120 s group, 1.0 W 30 s group, 1.0 W 60 s group, 1.0 W 120 s group, 1.5 W 30 s group, 1.5 W 60 s group, and 1.5 W 120 s group were treated by ultrasound with corresponding parameters. The cells viability was measured by a microplate reader after 24 hours of routine culture. Another batch of human keloid Fbs were divided into 5 groups, with 6 wells in each group. Cells in control group were given no treatment, while cells in 1, 10, 20, and 50 μg/mL blank lipid microbubble groups were treated with blank lipid microbubbles in corresponding mass concentration. The cells viability was measured as before after 24 hours of routine culture. Another batch of human keloid Fbs were divided into 6 groups, with 12 wells in each group. Cells in control group were given no treatment, while cells in 1, 10, 20, 50, and 100 μg/mL 4HPR-L groups were added with 4HPR-L carrying corresponding mass concentration of 4HPR. The cells viability in 6 wells of each group was detected after 24 and 48 hours of routine culture, respectively. Another batch of human keloid Fbs were divided into 4 groups, with 6 wells in each group. Cells in control group were given no treatment, while cells in 4HPR, 4HPR-L, and 4HPR-LM+ ultrasound groups were treated with 4HPR, 4HPR-L, and 4HPR-LM (all the mass concentration of 4HPR was 20 μg/mL), respectively, and cells in 4HPR-LM+ ultrasound group were given 0.5 W 60 s ultrasound treatment immediately after drug administration. The cells viability was measured as before after 24 hours of routine culture. (3) Another batch of human keloid Fbs were divided into control group, 4HPR group, 4HPR-L group and 4HPR-LM+ ultrasound group, with 3 wells in each group, and the cells in each group were treated as before. Apoptosis of the cells was detected by flow cytometer after 24 hours of routine culture. (4) Another batch of human keloid Fbs were grouped and treated as in (3), and then the cell cycle distribution was detected by flow cytometer after 24 hours of routine culture. Data were processed with one-way analysis of variance and t test. Results: (1) 4HPR-L particles had a spherical or spheroidal structure and were uniform in size, with particle size of (100.1±1.3) nm and Zeta potential of (-34.3±2.3) mV. The mass concentration of 4HPR in 4HPR-L solution was about 1 400 μg/mL, with the encapsulation efficiency of (95.8±1.2)% and drug loading rate of (8.3±0.4)%. (2) The viability of cells in the 12 ultrasound groups was higher than 93.0%, and the viability of cells in 1, 10, 20, and 50 μg/mL blank lipid microbubble groups was higher than 95.0%. The viability of cells in 1 μg/mL 4HPR-L group at administration hour 24 was similar to that at 48 (t=0.393, P>0.05). The viability of cells in 10, 20, 50, and 100 μg/mL 4HPR-L groups at administration hour 24 was significantly higher than that at administration hour 48 (t=44.593, 22.961, 32.224, 35.337, P<0.01). The viability of cells in 4HPR group, 4HPR-L group, and 4HPR-LM+ ultrasound group was (47.3±0.7)%, (42.3±1.7)%, and (38.6±0.8)%, respectively. The viability of cells in 4HPR group was significantly higher than that in 4HPR-L group and 4HPR-LM+ ultrasound group (t=4.551, 15.895, P<0.05 or P<0.01). The viability of cells in 4HPR-L group was significantly higher than that in 4HPR-LM+ ultrasound group (t=-3.360, P<0.05). (3) The percentages of total apoptotic cells in 4HPR group, 4HPR-L group, and 4HPR-LM+ ultrasound group were (32.8±2.4)%, (42.5±2.4)%, and (58.5±6.3)%, respectively, which were significantly higher than the percentage of control group [(14.9±1.6)%, t=8.748, 13.637, 9.500, P<0.01]. The percentages of total apoptotic cells in 4HPR-L group and 4HPR-LM+ ultrasound group were significantly higher than the percentage in 4HPR group (t=4.049, 5.393, P<0.05 or P<0.01), and the percentage of total apoptotic cells in 4HPR-LM+ ultrasound group was significantly higher than that in 4HPR-L group (t=3.371, P<0.01). (4) The percentage of G2/M phase cells in 4HPR group was higher than that in control group, but there was no statistically significant difference (t=2.107, P>0.05). The percentage of G2/M phase cells in 4HPR-L group was significantly higher than that in 4HPR group or control group (t=18.169, 30.026, P<0.01). The percentage of G2/M phase cells in 4HPR-LM+ ultrasound group was significantly higher than that in 4HPR-L group, 4HPR group, and control group (t=4.932, 25.854, 66.231, P<0.01). Conclusions: 4HPR can inhibit proliferation, induce apoptosis, and arrest G2/M phase of human keloid Fbs, and the effects of 4HPR-LM combined with ultrasound are better than those of 4HPR-L and free 4HPR.

Abstract
Objective: To explore the relationship between meat consumption and metabolic syndrome (MS) in Chinese adults aged ≥18 years. Methods: The data were obtained from 2010- 2012 National Nutrition and Health Survey. A total of 34 923 subjects who completed the dietary survey, the physical examination and had the testing results of blood sugar and blood lipid levels were enrolled in this study. MS was defined according to the diagnostic criteria of China Diabetes Society 2013. The prevalence ratios of MS and each form of MS and related 95%CI were calculated after post stratification weight according to the population data (2009) released by the national bureau of statistics. Results: The average meat intake among subjects was 94.8 g/d. People who had meat consumption between 100 g/d and 199 g/d had the lowest prevalence of MS, abdominal obesity and hyperglycemia. As the meat consumption increased, the prevalence of MS in men increased. Men who had meat consumption of ≥300 g/d had a higher risk of MS than those who had low level of meat consumption, with prevalence ratio equaled to 1.46 (95%CI: 1.14~1.87). Similar trend was not observed in women. Conclusion: Moderate intake of meat is associated with reduced risk of MS in Chinese adults.

Abstract
Objective: To understand the prevalence of alcohol drinking in 20-79 years old males with different educational backgrounds and smoking behaviors in different areas of China. Methods: A multi-stage cluster random sampling survey was conducted in 150 surveillance sites in 2010-2012 Chinese nutrition and health surveillance in China. At least 1 000 subjects were selected in each surveillance site. Alcohol drinking prevalence and pattern information were collected by using personal health and food frequency questionnaire in face to face interviews. Results: A total of 60 791 males aged 20-79 years were surveyed. The prevalence of alcohol drinking was 57.8% (58.3% in rural area, 57.3% in urban area). The mean daily alcohol intake level was 32.7 g (33.3 g in rural area, 32.1 g in urban area). The rate of almost drinking every day and daily alcohol intake level were highest among males aged 50-59 years. Mean daily alcohol intake level, rate of almost drinking every day and excessive drinking decreased with the increase of education level. Non-smokers had higher rate of never drinking and lower prevalence of drinking and excessive drinking, lower mean daily alcohol intake level, and lower rate of almost drinking every day compared with current and past smokers. Conclusions: Alcohol drinking was common in males aged 20-79 years in China, and, the difference was not obvious between rural residents and urban residents. The differences in daily intake level of different alcohol drinks among males with different characteristics had certain significance. Significant difference in excessive drinking was found among different age groups, those with different education levels and those with different smoking history.

Abstract
The aim of the present retrospective cohort study was to elucidate the clinical presentation of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) responders and non-responders in lung adenocarcinoma patients with common EGFR mutations. The cohort included 131 lung adenocarcinoma patients with common exon 19 or exon 21 EGFR mutations, who were receiving first-line EGFR-TKI therapy. The patient characteristics, treatment regimen and outcomes were recorded and analyzed. Of the 131 patients, 104 (79.3%) responded to treatment, while 27 (20.7%) did not. A significantly longer median progression-free survival (PFS) [14.3, 95% confidence interval (CI): 12.2-18.4 vs. 5.7, 95% CI: 2.7-9.9 months; P<0.001] and overall survival (OS) (42.2, 95% CI: 28.1-58.1 vs. 11.5, 95% CI: 8.3-19.7 months; P<0.001) were observed in responders compared with non-responders. In responders, bone [hazard ratio (HR)=1.87, 95% CI: 1.11-3.20, P=0.021] and pleural (HR=2.40, 95% CI: 1.37-4.22, P=0.002) metastasis were independent factors of PFS. Exon 19 mutations (HR=0.38, 95% CI: 0.19-0.76, P=0.006), Eastern Cooperative Oncology Group performance status score ≥2 (HR=3.53, 95% CI: 1.42-8.75, P=0.007) and bone metastasis (HR=2.01, 95% CI: 1.05-3.85, P=0.034), were independent factors of OS. In non-responders, smoking (HR=3.97, 95% CI: 1.13-13.91, P=0.031) was an independent factor of PFS. Different survival-associated factors were observed between EGFR-TKI responders and non-responders. The development of new treatment strategies should be advocated in EGFR-TKI non-responders.

Abstract
Objective: To analyze the clinical characteristics of X-linked inhibitor of apoptosis (XIAP) deficient patients with clinical manifestation of Crohn's disease. Methods: Clinical manifestations, laboratory investigations, genetic testing and therapeutic interventions of one case of XIAP deficiency who was admitted to Department of Gastroenterology in Children's Hospital, Zhejiang University School of Medicine in May 2016 were summarized. PubMed and Chinese database for articles published from January 2016 to June 2017 were searched using the key words of'Crohn's disease'and'XIAP', and the relevant literature was reviewed. Results: The case we reported was a 6-year-1-month-old boy with recurrent bloody stool for 2 months, and abdominal pain with fever for 2 weeks. The patient had a past history of hemophagocytic lymphohistiocytosis (HLH) and epilepsy in the past one year. Complete blood cell count showed mild anemia (Hb108 g/L). The patient had an elevated high-sensitivity C reactive protein (86 mg/L) and erythrocyte sedimentation rate (46 mm/1h) . White blood cells, pus cells and red blood cells were found on routine stool examination. Biochemical panel showed hypoalbuminemia (25.2 g/L) , elevated transaminase (alanine aminotransferase 175 U/L, aspartate transaminase 229 U/L) , hypertriglyceridemia (4.41 mmol/L) , and hyperferritinemia (>1 650.0 μg/L) . Magnetic resonance enterography revealed the intestinal wall thickening and increased enhancement in parts of illeum and colon. Capsule endoscopy revealed multiple ulcers in jejunum. Colonoscopy showed multiple ulcers in colon and the pathological examination revealed chronic inflammation in mucosa of terminal ileum and colon, which was combined with partial necrosis and ulceration. Some phagocytes were seen in bone marrow smears. The patient was given multiple diagnoses, including hemophagocytic lymphohistiocytosis, Crohn's disease, sepsis, epilepsy, severe malnutrition, and hypoproteinemia. The pediatric Crohn's disease activity index (PCDAI) was 37.5. Genetic testing identified a hemizygotic mutation of c.910G>T chrX:123022501 p.G304X in XIAP. The parents had no such mutation. The patient showed response to infliximab with oral intake of mercaptopurine and corticosteroids, and had remission with PCDAI of 0. There were 9 relevant articles (Chinese 0 English 9), which showed 33.3% XIAP deficient patients manifested with inflammatory bowel disease(IBD), who might have other manifestations such as hemophagocytic lymphohistiocytosis or splenomegaly simultaneously or sequentially. Those patients showed poor response to monotherapy. Conclusion: XIAP deficient patients have various clinical manifestations. Genetic testing is important to those male pediatric IBD patients who have the complicated symptoms or little response to standard therapy.

Abstract
Purpose Hypertrophic pulmonary osteoarthropathy (HPOA) is a rare disease that most commonly occurs secondary to lung cancer. However, the clinical significance of HPOA remains unclear. The aim of this study was to evaluate the impact of HPOA on patients with lung cancer in Taiwan. Patients and methods Data regarding lung cancer patients who demonstrated findings of HPOA on bone scintigraphy between 2010 and 2016 were retrospectively analyzed. Pathological confirmation of cases was conducted at Chiayi and Kaohsiung Chang Gang Memorial Hospital. Clinical characteristics, including gender, smoking status, histology subtype, clinical stage, and epidermal growth factor receptor (EGFR) status were investigated. Results We identified 69 lung cancer patients with typical HPOA findings on bone scintigraphy. Among them, 56 were male (81.2%) and 51 were ex-smokers or current smokers (73.9%). Adenocarcinoma was the most common histology subtype (n=42, 60.9%). Of 34 patients subjected to EGFR mutation analysis, only 4 (11.8%) had EGFR-tyrosine kinase inhibitor (EGFR-TKI)-sensitive mutations. Conclusion Male, smoking, and adenocarcinoma were the most common clinical characteristics of lung cancer patients with HPOA in our cohort. However, the proportion of EGFR-TKI-sensitive mutation cases was extremely low.

METHOD Retrospective analysis of disease spectrum, EN approach, preparation, speed and time as well as adverse reactions and outcomes in 47 pediatric patients with gastrointestinal disease underwent EN therapy during July 2014 to March 2015. The nutrition indicators before and after EN therapy were compared by paired t-test. RESULT A total of 47 patients were selected, 27 male (57%) and 20 female (43%), aged 0.8 (0.3, 4.0) years, 9 with mechanical or chemical damage to the esophagus, 7 with inflammatory bowel disease (including ulcerative colitis and Crohn's disease), 6 with chronic diarrhea, 5 with acute pancreatitis, 3 with acute diarrhea and severe malnutrition, 3 with short bowel syndrome, 3 with improper feeding, 3 with feeding difficulties, 3 with protein losing enteropathy, 2 with post-enterostomy, 2 with enterocolitis, 1 with gastroesophageal reflux, were diagnosed. Of 47 cases, 22 were given oral nutrition, 28 were fed with nasogastric tube and 4 with nasojejunal tube feeding, 2 with percutaneous endoscopic gastrojejunostomy tube feeding for each. In these tube-feeding cases, 20 cases were treated with continuous infusion and 21 cases with intermittent infusion. Eleven cases were fed with amino acid formula; 21 cases took the choice of peptide formulations; 16 cases chose whole protein formula, including six cases who chose 3.3-4.2 kJ/ml higher energy density formula, 10 cases selected common energy density formula including breast milk. Twenty-one cases suffered from different degrees of adverse reactions, including vomiting in 7 cases, abdominal pain and bloating in 3, diarrhea in 12, secondary respiratory infections in 5. Five patients were discharged after giving up of treatment by parents due to poor efficacy on primary disease; 3 cases were transferred to other departments for further treatment; 15 cases were discharged with a feeding tube for family nutrition and specialist out-patient treatment. The rest 24 cases were all improved and discharged. There were significant differences in nutrition indicators before and after EN, weight-for-age Z score (WAZ)(-2.3±1.9 vs. -1.9±1.8, t=4.156, P=0.000), weight-for-height Z score (WHZ)(-1.9±1.7 vs. -1.2±1.5, t=3.714, P=0.001), albumin ((35±9)g/L vs.(39±6) g/L, t=3.017, P=0.005) and prealbumin ((0.11±0.05)g/L vs.(0.18±0.07)g/L, t=5.144, P=0.000). CONCLUSION EN is suitable for a variety of children's digestive diseases, which can improve the nutritional status of the patients and was safe for clinical application. As the implementation of EN is simple and has good compliance, family EN is proven to be feasible.

Abstract
This study aimed to elucidate the association of the content of mutant epidermal growth factor receptor (EGFR) deoxyribonucleic acid (DNA) with the treatment response to EGFR-tyrosine kinase inhibitor (TKI) and survival in patients with lung cancer.This retrospective cohort study included 77 lung adenocarcinoma patients with common EGFR mutations from December 2012 to February 2015. The content of mutant EGFR DNA in lung cancer tissues was determined using an Amplification Refractory Mutation System. The association of the amount of mutant EGFR DNA with treatment response, the clinical variables, and the progression-free survival (PFS) after EGFR-TKI therapy were evaluated.Using the amount of mutant EGR DNA above 4.77% as the cut-off value, the sensitivity to predict EGFR-TKI responder is 82.0% and the specificity is 75.0% (area under the curve [AUC]: 0.734, P = 0.003). The high content of mutant EGFR DNA is an independent factor associated with the response to EGFR-TKIs (odds ratio: 13.07, 95% confidence interval [CI]: 3.23-52.11, P = 0.0003). A significantly longer PFS was observed in the group with the high content of mutant EGFR DNA (26.3 months, 95% CI: 12.2-26.3) compared with the low content of mutant EGFR DNA groups (12.3 months, 95% CI: 5.7-14.8, P = 0.0155). A better predictive value of the content of mutant EGFR DNA was noted in patients with exon 19 deletions (AUC: 0.892, P < 0.0001) than exon 21 L858R mutations (AUC: 0.675, P = 0.0856).Our results show that the content of mutant EGFR DNA is associated with the clinical response to EGFR-TKIs, especially in patients with exon 19 deletions mutation.

Abstract
Encapsulation of transplanted cells within an immunoisolating membrane may provide a new strategy for protecting these cells from recipient immune responses without the use of immunosuppressive drugs. We have previously reported a novel concept of immunoisolation and immunodelusion using recipient cells instead of traditional artificial materials. We developed a chondrocyte sheeting immunodelusive immunoisolated bioartificial pancreas (CSI-BAP) that would enable transplantation of cells across allogeneic and xenogeneic barriers without the cells being recognized as donor cells and without the need for immunosuppression. Recently, we have constructed hybrid cellular spheroids (HCSs) containing cells from two different cell lines (RIN-5F, an insulin-secreting cell line, and Hep-G2, a hepatocellular carcinoma cell line) to enhance the function and biocompatibility of the HCSs. These HCSs were then encapsulated with multiple layers of chondrocyte sheets obtained from the auricular cartilage of Sprague-Dawley (SD) rats. The in vitro ability of the CSI-BAP to secrete insulin was tested before transplantation. Histological evaluation of CSI-BAP chondrocyte microencapsulated immunoisolated islet morphology and viability of allogeneic or xenogeneic cell lines was performed 100 days after the CSI-BAP was transplanted into SD rats. Morphological evaluations revealed good viability of the islets and progression of islet encapsulation. In vitro insulin secretion from the CSI-BAP was well maintained. Additionally, insulin and albumin secretion from the CSI-BAP was confirmed by in vivo immunohistochemical examination. Moreover, the cell lines transplanted into the subcutaneous space in the form of HCSs within the chondrocyte sheets showed good viability of more than 100 days and sustained insulin and albumin secreting ability.

Abstract
Improving human islet transplantation is often limited by the shortage of donors and the side effects of immunosuppressive agents. If immunoisolation is properly used, it can overcome these obstacles. Because artificial materials are adopted in this technique, however, there are still multiple issues with biocompatibility and foreign body reactions. We developed a chondrocyte microencapsulated immunoisolated islet (CMI-islet) that allows living cells to act as the immunoisolating material. To manufacture CMI-islets for xenotransplantation, isolated rat pancreatic islets were placed on low cell-binding culture dishes. Subsequently, expanded canine auricular cartiage primary cells were seeded on these dishes at a high density and maintained in a suspended state via a shaking culture system. Morphological evaluations showed good islet viability and a clear progression of the islet- encapsulation events. When the cells were challenged with glucose, they were able to secrete sufficient insulin according to glucose concentrations. The CMI-islets responded better to the glucose challenge than did nude pancreatic islets and created better glucose-insulin feedback regulation. Moreover, insulin secretion into the culture medium was confirmed over a period of 100 days, showing the survival and secretory capacity of the CMI-islet cells. By microencapsulating pancreatic islets with recipient ear cartilage cells, long-term insulin secretion can be maintained and the response to glucose challenges improved. This new immunodelusion technology differs from other immunoisolation techniques in that the donor tissue is enclosed with the recipient's tissue, thus allowing the transplanted cells to be recognized as recipient cells. This microencapsulation method may lead to developing viable xenotransplantation techniques that do not use immunosuppressive drugs.

Abstract
BACKGROUND In sudden cardiac arrest, the effective maintenance of coronary artery blood flow is of paramount importance for myocardial preservation as well as cardiac recovery and patient survival. The purpose of this study was to directly compare the effects of pulsatile versus non-pulsatile circulation to coronary artery flow and myocardial preservation in a cardiac arrest condition. METHODS A cardiopulmonary bypass circuit was constructed in a ventricular fibrillation model using fourteen Yorkshire swine weighing 25-35 kg each. The animals were randomly assigned to group I (n=7, non-pulsatile centrifugal pump) or group II (n=7, pulsatile T-PLS pump). Extracorporeal circulation was maintained for two hours at a pump flow of 2 L/min. The left anterior descending coronary artery flow was measured with an ultrasonic coronary artery flow measurement system at baseline (before bypass) and at every 20 minutes after bypass. Serologic parameters were collected simultaneously at baseline, 1 hour, and 2 hours after bypass in the systemic arterial and coronary sinus venous blood. The Mann-Whitney U test of STATISTICA 6.0 was used to determine intergroup significances using a p value of <0.05. RESULTS The resistance index of the coronary artery was lower in group II and the difference was significant at 40 min, 80 min, 100 min and 120 min (p<0.05). The mean velocity of the coronary artery was higher in group II throughout the study, and the difference was significant from 20 min after starting the pump (p<0.05). The coronary artery blood flow was higher in group II throughout the study, and the difference was significant from 40 min to 120 min (p<0.05) except at 80 min. Serologic parameters showed no differences between the groups at 1 hour and 2 hours after bypass in the systemic and coronary sinus blood (p=NS). CONCLUSION In the cardiac arrest condition, pulsatile extracorporeal circulation provides more blood flow, higher flow velocity and less resistance to coronary artery than non-pulsatile circulation.

Abstract
The effect of chronic exogenous testosterone (T) treatment on neuromuscular transmission in the diaphragm (Dia) muscle of adult male rats was determined. The contribution of neuromuscular transmission failure (NTF) to Dia fatigue was evaluated by superimposing intermittent direct muscle stimulation on repetitive nerve stimulation of isometric contraction in vitro. T treatment significantly reduced the contribution of NTF to Dia fatigue by approximately 20% (P < 0.001). Fiber type-specific effects on NTF were determined by measuring Dia fiber glycogen levels subsequent to repetitive nerve or muscle stimulation. T treatment had no effect on glycogen depletion in Dia type I and IIa fibers regardless of stimulation route. In the control group, type IIx fibers demonstrated significantly less glycogen depletion after nerve stimulation compared with direct muscle stimulation (P < 0.05), suggesting the presence of NTF. In contrast, T treatment increased glycogen depletion of type IIx fibers during nerve stimulation to levels similar to those after direct muscle stimulation. These data indicate that testosterone treatment substantially improves neuromuscular transmission in the Dia.

Abstract
It has been found that maximum specific force (F(max); force per cross-sectional area) of rat diaphragm muscle doubles from birth to 84 days (adult). We hypothesize that this developmental change in F(max) reflects an increase in myosin heavy chain (MHC) content per half-sarcomere (an estimate of the number of cross bridges in parallel) and/or a greater force per cross bridge in fibers expressing fast MHC isoforms compared with slow and neonatal MHC isoforms (MHC(slow) and MHC(neo), respectively). Single Triton 100-X-permeabilized fibers were activated at a pCa of 4.0. MHC isoform expression was determined by SDS-PAGE. MHC content per half-sarcomere was determined by densitometric analysis and comparison to a standard curve of known MHC concentrations. MHC content per half-sarcomere progressively increased during early postnatal development. When normalized for MHC content per half-sarcomere, fibers expressing MHC(slow) and coexpressing MHC(neo) produced less force than fibers expressing fast MHC isoforms. We conclude that lower force per cross bridge in fibers expressing MHC(slow) and MHC(neo) contributes to the lower F(max) seen in early postnatal development.
