Abstract
Objective: To understand the seasonal distribution of patient hospitalization due to asthma exacerbation in 7 geographic areas in China. Methods: This was a retrospective study which involved patients hospitalized for asthma exacerbation in 29 hospitals throughout 7 geographic areas in the mainland of China (northeast, north, central, east, south, northwest and southwest). The numbers of asthmatic patients and total inpatients of the respiratory department of each hospital were recorded. The monthly ratio of asthmatic patients to the total inpatients in every area was calculated and compared. Results: During the study period, 6 480 patients were admitted for asthma exacerbation, accounting for 3.14% of all the 206 135 patients admitted to the respiratory departments in the 29 hospitals. The ratio of asthmatic patients to total inpatients in the northeast area (5.61%) was highest, and the ratio in east area was lowest (1.97%). Statistical analysis showed that the difference among different areas was significant (P<0.000 1). In most areas, both the number and proportion of hospitalized asthmatic patients peaked in spring (February-April) and autumn (September-October). In the northeast area, east area and south area, the peaks in spring were more obvious, while in the north area and southwest area, the peaks in autumn were more obvious. In the northwest area the peaks occurred in winter (December-January) and summer (June-August), respectively. The differences in hospitalization due to asthma among different months were significant in the northeast, north, and southwest areas (P<0.005). Conclusion: The number of patients hospitalized for asthma exacerbation fluctuated with season in different areas in China. In most areas, more asthmatic patients were admitted to hospitals in spring and autumn.

Abstract
Objective: To understand the epidemiological and etiological characteristics of mumps in Fujian province, 2005-2017. Methods: All the reported mumps cases were collected through the National Notifiable Disease Information Management System, 2005-2017. Active search and interviews were conducted to collect the information on vaccination of mumps. Throat swab specimens were collected for cells culture, genotyping and gene sequence analysis on mumps virus (MuV). Results: A total of 83 959 cases of mumps were reported in Fujian province from 2005 to 2017, with an average annual incidence of 17.6 per 100 000. Since 2007, the incidence appeared increasing but then decreasing, reaching the lowest level (7.5 per 100 000), after the setup of a monitoring program. Annually, the onset time of mumps showed an obvious two seasonal peaks, one from April to July, with a weakening trend, and the other from October to January with a rising trend. Most of the mumps cases occurred among students, kindergarten and scattered children (89.2%, 5 814/6 517), children aged 5-9 years (38.8%, 2 527/6 517), with cases reported from every region. Program from the pathogen surveillance showed that the transmission chain of G genotype mumps virus did exist in Fujian. Data from the sequence analysis revealed that mutations in the nucleotide of G genotype strain in 2015 had led to mutation of 6 amino acid sites in the SH gene coding region, resulting in the differences appearing in both nucleotide and amino acid homology with type A vaccine strain. Conclusions: The incidence of mumps decreased annually, in Fujian. Prevention programs should focus on primary and secondary school students. In Fujian province, we also noticed the transmission chain of mumps G genotype with some amino acid mutations in the SH gene coding region. Monitor programs on both epidemiologic and etiology, should be strengthened.

Abstract
Objective: To study the seasonal characteristics of patients hospitalized for asthma exacerbation in China. Methods: This was a retrospective study which involved patients hospitalized for asthma exacerbation in 29 hospitals throughout mainland China during 2013-2014. The number of patients hospitalized for asthma exacerbation in each hospital was calculated, as well as the ratio of asthmatic patients to all the hospitalized patients. The analysis by month was conducted. The number and ratio of asthmatic patients in the northern and southern cities were calculated respectively. Results: During the study period, there were 6 480 patients hospitalized for asthma exacerbation, accounting for 3.14% (6 480/206 135) of all the hospitalized patients of the respiratory department in 29 hospitals. The analysis by month showed that the ratio of patients hospitalized for asthma exacerbation was highest in March (3.49%), then declined from April to June, then rose again from July, reaching a second peak at September (3.28%), and then declined again from October to December. The ratio of asthmatic patients in every month was higher in northern cities than in southern cities. Conclusions: The ratio of patients hospitalized for asthma exacerbation in China fluctuates with the changes of seasons, and March and September are the two peak months. Northern cities have a higher ratio of asthmatic patients than southern cities.

Abstract
Objective: To investigate warning symptoms of asthma attack and evaluate asthma self-management status of asthma patients in urban China. Methods: A multi-center, cross-sectional, questionnaire-based survey was carried out from 30 general hospitals dispersed in 30 provinces of mainland China (except for Tibet) during Oct 2015 to May 2016. Information of frequency and warning symptoms of asthma attack, the time from warning symptoms to asthma attack, the impact of asthma attack and asthma self-management were collected from asthma patients of outpatient department. Results: Altogether 3 875 asthmatic outpatients were recruited. 78.1% (3 026/3 875) of the patients reported restriction of exercise and daily activities during asthma exacerbation. 82.5% (3 160/3 829) of the patients had warning symptoms before asthma attack, the most common warning symptoms were cough, chest tightness and shortness of breath. The median time from warning symptoms to asthma attack was 2 h, the mean time was 90 h. Only 4.4% (167/3 829) of the patients had definite confidence to control asthma when symptoms deteriorated. 76.7% (2 937/3 828) of the patients used medications to control asthma when asthma symptoms deteriorated. Medication choice: inhaled corticosteroid (ICS) + formoterol 45.8% (1 776/3 875), short-acting beta-agonist (SABA) 23.9% (927/3 875). Conclusions: Most asthma patients have warning symptoms before asthma attack, the most common symptoms are cough, chest tightness and shortness of breath. The proportion of patients conducting effective asthma self-management remains low.

Abstract
Objective: To assess the overall asthma control level in urban China. Methods: A multi-center, cross-sectional, questionnaire-based survey was carried out in 30 provinces in China (except Tibet). Asthmatic outpatients who met the inclusion criteria were recruited consecutively from 30 sub-centers from October 2015 to May 2016. Data of demographic characteristics, asthma control, asthma management, asthma exacerbations and self-management, and disease perception were collected by face-to-face interviews. Results: Totally 3 875 asthmatic outpatients were recruited. Asthma control level was assessed according to GINA 2015. The prevalence of asthma control was 28.5%(1 099/3 854). Among 10 cities, which were also involved in the asthma control survey in 2008, the level of asthma control improved from 28.7% in 2008 to 39.2%(533/1 361) in 2016. The rate of hospitalizations due to asthma exacerbations was 26.4%(1 017/3 858) and the rate of emergency visits was 22.4%(864/3 858). Among adult patients, 18.4%(568/3 092) of them had been absent from work while 63.6%(63/99) adolescent patients had been absent from school because of asthma attacks in the previous year. Conclusion: Although the level of asthma control in China is still far from ideal at present, the status has been improved in some cities. Poorly controlled asthma resulted in increase of hospitalizations, emergency department visits and work/school absences.

Abstract
Objective: To study the characteristics of patients hospitalized for asthma exacerbation in 29 teaching hospitals in China and to evaluate the hospitalization costs of these patients. Methods: This was a retrospective study and involved patients hospitalized for asthma exacerbation in 29 hospitals throughout China during 2013-2014. Information about the demographic features, conditions before the admission, the outcome, the complications, and the costs was collected using the pre-designed case report form. The influencing factors of the hospitalization costs were analyzed. Results: 3 240 asthmatic patients (1 369 males and 1 871 females) were included and data were analyzed. There were 41.5% (1 346/3 240) patients who had a history of previous hospitalization or emergency department visits during the last year. Only 28.0% (907/3 240) patients had used asthma-controlling medications regularly before the admission. Seventy-three(2.3%) patients were admitted to ICU and used mechanical ventilation. Mortality among these patients hospitalized for asthma exacerbation was 0.25% (8/3 240). The median hospitalization costs was 9 045(6 431, 13 035) RMB. The costs of medications, examinations and treatment accounted for 52.1%, 27.6%, and 9.6% respectively. The costs of asthma medications accounted for only 22.7% of the total medication costs, while the costs of antibiotics accounted for 44.0%. The patients who were admitted to ICU, used mechanical ventilation, complicated with pneumonia, or had a history of hospitalization or emergency department visits during the last year due to asthma exacerbations tended to cost more. Conclusion: In this study, we demonstrated that only a minority of the patients had used asthma controllers regularly before the admissions with exacerbations. The in-hospital mortality of asthma patients in this study was much lower than that reported in other countries. The average cost of hospitalization was much higher than the yearly cost of maintenance therapy. Medication was the predominant component of the total hospitalization costs, and the costs of antibiotics made up the major part of the total medication costs.

Abstract
Most of the existing robots would find it difficult to stretch and transform all parts of their body together due to rigid components and complex actuation mechanisms inside. Here, we presented a highly transformable liquid-metal composite (LMC) that is easy to change shape in large magnitude and resume its original state again according to need. When subject to heating, part of the ethanol droplets embedded in the composite would change phase and then actuate. We demonstrate the flexible transformation of LMC-made octopus from a two-dimensional shape into several predictable three-dimensional shapes freely on a large scale (even up to 11 times its initial height) through remote wireless heating, which needs no sophisticated operating system at all. Further, several designed behaviors, such as movement of octopus and entangling objects of soft robots, are also realized. Theoretical analysis of the heating-induced liquid-vapor transition of the embedded ethanol droplet interprets the mechanisms involved. The present findings open a new way to fabricate functional transformable composites that would find significant applications in developing future generation soft robots.

Abstract
Objective: To study the treatment of patients hospitalized for asthma exacerbation in China. Methods: This was a retrospective study and involved patients hospitalized for asthma exacerbation in 29 hospitals throughout China during Jan 2013 to Dec 2014. Information of the demographic features, the severity of the exacerbation, the medicine prescribed during the hospitalization and the use of mechanical ventilation were collected and analyzed. Results: During the study period, there were 3 240 patients hospitalized for asthma exacerbation, and 1 369(42.3%) of them were males 1 871(57.7%)were females. Patients of mild, moderate, severe, and life-threatening exacerbation counted for 41.7%, 37.8%, 19.2% and 1.0%, respectively of the total patients. Of all the patients, 72.6% used bronchodilators by nebulizer, 70.8% used inhaled corticosteroids by nebulizer, 60.5% used intravenous corticosteroids, 17.3% used oral corticosteroids, and 80.5% used antibiotics. The percentages of patients using systemic corticosteroids and antibiotics were higher in patients with more severe exacerbation. In patients with mild exacerbation, there were 74.9% and 52.2% who used antibiotics and systemic corticosteroids, respectively. A total of 73 patients (2.3%) used mechanical ventilation, and 62 of them used noninvasive ventilation, 16 used invasive ventilation, and 5 used both. Conclusions: Nebulizer therapy has been accepted as the main administration route of medicine in the treatment of asthma exacerbation. A large amount of patients used antibiotics and systemic corticosteroids during hospitalization, indicating there may be some overuse of these medicines.

Abstract
Objective: In order to evaluate disease perception of asthma patients in urban China and provide evidence for further specific patient education. Methods: A multi-center, cross-sectional, questionnaire-based survey was carried out in 30 general hospitals dispersed in 30 provinces of mainland China (except for Tibet) during Oct 2015 to May 2016. Information of disease perception [Question 1: the disease nature of asthma; Question 2: medication choice of first-line in chronic asthma; Question 3: the occasion of using short-acting aerosols of receptor agonists; Question 4: perception of asthma treatment goal; Question 5: reason for not using peak flow meter (PFM)] were collected from asthma patients of outpatient department. These results were compared with the same type of survey results from 2007-2008. Results: Altogether 3 875 asthmatic outpatients were recruited. 69.0% (2 660/3 857) of the patients had right perception on the disease nature of asthma, 60.2% (2 321/3 857) of the patients considered inhaled corticosteroids (ICS)/inhaled corticosteroids plus long-acting beta2-agonists (ICS+ LABA) as daily-used first-line medication for chronic asthma. 85.7% (3 277/3 823) of the patients had right perception on the condition of using short-acting beta2-agonists (SABA). 75.4% (2 761/3 661) of the patients had right perception on asthma treatment goal. Only 10.1% (388/3 837) of the patients used PFM. Of the reasons for not using PFM, 65.2% (2 518/3 860) of the patients chose doctors never introduced. Among the 10 cities, which were also involved in the asthma control survey in 2007-2008, 71.1% (968/1 361) of the patients had right perception on the disease nature of asthma, 61.6% (839/1 362) of the patients considered ICS/ICS+ LABA as daily-used first-line medication for chronic asthma. 88.7% (1 207/1 361) of the patients had right perception on the condition of using SABA. 74.5% (1 013/1 360) of the patients had right perception on asthma treatment goal. 17.9% (244/1 360) of the patients used PFM. Of the reasons for not using PFM, 76.2% (931/1 221) of the patients chose doctors never introduced. Compared to the survey conducted in 2007-2008, the perception on disease nature and medication choice as daily-used first-line medication for chronic asthma significantly improved, the perception on occasion of using SABA and asthma treatment goal was comparable, while the rate of PFM usage showed no significant improvement. In reasons of not using PFM, doctors never introduced ranked the first. Conclusions: Compared to the similar survey conducted in 2007-2008, the overall status of disease perception of asthma patients has been improved in urban China, while the rate of PFM usage showed no significant improvement. Asthma education on asthma and asthma self-management should be further pushed forward.

Abstract
Objective: To study the mortality and death-related risk factors of patients hospitalized for asthma exacerbation in Chinese urban areas. Methods: A retrospective study was carried out in 29 hospitals of 29 provinces throughout mainland China. Patients hospitalized for asthma exacerbation during 2013-2014 in each hospital were included. For each patient, information about demography, admission time, comorbidities, severity of diseases, intense care unit (ICU) admission, use of mechanical ventilation and the outcome was obtained. The mortality of patients hospitalized for asthma exacerbation was calculated, and the basic information and causes of death of the patients who died were summarized. The death-related risk factors and numbers of comorbidities were compared between the patients who survived and those who died during hospitalization. Results: A total of 3 240 patients (median age 57.0) were included and among them 8 patients (median age 68.5) died. The mortality of patients hospitalized for asthma exacerbation was 0.25%. All the patients who died were admitted during the winter and spring. One patient died of acute myocardial infarction, one of cardiac shock, one of tension pneumothorax, one of sudden death, one of respiratory failure and three of unknown causes. The average number of comorbidities of patients who died was 1.10, larger than that of patients who survived (0.83) (P>0.05). More patients had diabetes, coronary artery diseases and hypertension as comorbidities in the patients who died (2/8) than those who survived[7.6% (246/3 232), 7.6% (246/3 232), 22.6% (731/3 232), respectively](all P>0.05). Conclusions: The in-hospital mortality of patients hospitalized for asthma exacerbation of China in this study is low. The patients who died are much older, and with more comorbidities, and a higher percentage of comorbidities such as diabetes, coronary artery diseases, and hypertension.

Abstract
Objective: To investigate the expression of mismatch repair (MMR) proteins (MLH1, MSH2, MSH6 and PMS2) in colorectal cancers and to explore the relationship between MMR expression and clinicopathologic features. Methods: Six hundred and fifty-eight colon cancers were collected from January 2016 to January 2017 at Shengjing Hospital of China Medical University. Of the 658 patients there were 409 male and 249 female. The patients were 20 to 92 years old, with average age of (63±5) years old. Expression of MLH1, MSH2, MSH6 and PMS2 protein was detected by immunohistochemical method. Immunohistochemistry for BRAF V600E was performed in colorectal cancers with loss of MLH1 protein expression. Relationship between MMR protein expression and clinicopathologic features was analyzed statistically. Results: Forty-four cases of 658 cases (6.7%) lost at least one MMR protein expression. Expression deficiency rates of MLH1, MSH2, MSH6 and PMS2 were 4.1%(27/658), 2.3%(15/658), 2.4% (16/658), and 4.3% (28/658), respectively. MMR expression deficiency mainly consisted of combined loss of MLH1/PMS2 (61.4%, 27/44) and MSH2/MSH6 (34.1%, 15/44). Two unique mutations were identified including one MSH6-deficient(2.3%, 1/44) and PMS2-deficient(2.3%, 1/44). Seven cases (25.9%, 7/27) had positive BRAF V600E expression, suggesting BRAF gene mutation related sporadic colorectal cancers. No correlation was observed between the expression of MMR and depth of tumor infiltration, lymph node metastasis, vascular tumor emboli, clinical stage or hematogenous metastasis (P>0.05). MMR status was associated with tumor cell differentiation, histological type and tumor location (P<0.01). Tumors with combined MLH1 and PMS2 loss were associated with mucinous differentiation (P=0.049, P=0.013) and located in the right hemi-colon (P=0.006, P=0.002). Combined MSH2 and PMS2 loss was related to gender, while loss of MSH2 protein was observed more frequently in female patients (P=0.048) and loss of PMS2 protein was seen more frequently in male patients (P=0.031). Conclusions: Patients with MMR protein deficiency have a younger onset age and poorly differentiated tumors. Most tumors are located in the right hemi-colon and have mucinous differentiation.

Abstract
Objective: To explore the prevalence and clinical characteristics of postprandial hypotension(PPH) in patients with essential hypertension and coronary heart disease. Methods: A total of 197 patients with essential hypertension and coronary heart disease, who had been treated in the First Department of Cardiology of the Second Hospital of Hebei Medical University from December, 2013 to December, 2014 were included. The patients' blood pressure before breakfast, lunch and dinner and 30, 60, 90, 120 minutes after the meal were monitored. Subjects were classified into PPH group (n=37) and non-PPH group (NPPH, n=160) according to postprandial decrease in systolic blood pressure, to explore the clinical characteristics and related factors and the major adverse cardiac and cerebral vascular events of PPH. Results: Among 197 patients, 37 cases (18.8%) showed at least once postprandial decline in systolic blood pressure greater than and equal to 20 mmHg. The incidence of PPH after breakfast and dinner were higher than lunch (P<0.05). There was no significant difference in the incidence of PPH among different age groups, among patients accompanied with different diseases, and among patients with different dining position (all P>0.05). According to the baseline systolic blood pressure, patients can be divided into 4 groups(<120 mmHg, 120-129 mmHg, 130-139 mmHg, >140 mmHg), the higher the level of the baseline systolic blood pressure was, the higher the incidence of PPH was. And the incidence of major adverse cardiac and cerebral vascular events in patients during hospitalization were increased by PPH. Conclusions: The prevalence of PPH in the patients with essential hypertension and coronary heart disease is 18.8%. The incidence of PPH after breakfast and dinner is higher than lunch. The baseline systolic blood pressure is considered to be the risk factor of PPH. And PPH could lead to an increase of the incidence of major adverse cardiac and cerebral vascular events.

Abstract
Objective: To investigate the current perception of disease among asthmatic patients in Chinese urban areas, and to address its association with asthma control. Methods: This was a nationwide, multi-center, cross-sectional study covering 30 third-level, grade A hospitals in 30 provinces, municipalities and autonomous regions (not including Tibet) across Chinese mainland. The survey was carried out from October 2015 to May 2016. Asthmatic outpatients were selected to receive face-to-face questionnaire survey on asthma control including Asthma Control Test (ACT) score, classification of asthma control level[according to the Global Initiative for Asthma (GINA) 2015 classification system, as assessed by the physician completing the survey], perception of asthma (including question 1: nature of asthma as a disease; question 2: selection of first-line therapeutic agents to be regularly used daily for asthma; question 3: appropriate timing of the use of short-acting aerosols of β(2) receptor agonists; and question 4: therapeutic goals for asthma). Results: A total of 3 875 asthmatic outpatients were included; among them, 69.0% (2 660/3 857) were aware that asthma is "an airway inflammatory disorder resulting from the combined effects of heredity and environment" ; 60.2% (2 321/3 857) considered "inhaled glucocorticoids or their compound preparations" to be the first-line therapeutic agents to be regularly used daily for patients with persistent chronic asthma; 85.7% (3 277/3 823) considered it appropriate to use short-acting aerosols of β(2) receptor agonists "as needed in the event of disease aggravation or acute exacerbation" ; and 75.4% (2 761/3 661) were aware that asthma "can be adequately or completely controlled in the long term" . The ACT score[20 (16, 23) vs 19 (16, 22) points; Z=-3.928, P<0.001]and asthma control rate (29.92% vs 25.31%; χ(2)=8.616, P=0.003) were significantly higher, and the rate of uncontrolled asthma (19.92% vs 23.48%; χ(2)=6.267, P=0.012) was significantly lower among the 2 660 (69.0%) patients correctly answering question 1 than among the 1 197 (31.0%) patients giving incorrect answer. The ACT score[21 (17, 23) vs 19 (15, 22) points; Z=-9.190, P<0.001] and asthma control rate (32.66% vs 22.20%; χ(2)=49.614, P<0.001) were significantly higher, and the rate of uncontrolled asthma (18.40% vs 25.00%; χ(2)=24.267, P<0.001) was significantly lower among the 2 321 (60.2%) patient correctly answering question 2 than among the 1 536 (39.8%) patients giving incorrect answer. Conclusions: Compared to previous surveys, there has been improved perception of disease among asthmatic patients in Chinese urban areas. Correct perception of disease is favorable for improving asthma control level.

Abstract
Objective:To evaluate the effect of systemic and intratympanic dexamethasone combination therapy on sudden deafness.Method:A total of 98 patients randomly divided into three groups: an intravenous corticosteroid (systemic corticosteroid monotherapy group); an intratympanic corticosteroid (IT monotherapy group); and a combination therapy group (IT plus systemic combination group). All patients were treated additionally with ginkgo-damole and mecobalamine and proton pomp inhibitor. An audiometry was performed before and after the therapies in all patients. Result:Of the total of 98 patients, 39 were receiving systemic corticosteroids, 28 received intratympanic(IT) corticosteroids, and 31 were receiving a combination of the two. A total of 65 patients (66.3%) responded positively to corticosteroid therapy. No significant differences were observed between the three groups (systemic group, IT and combination therapy group) in their overall response to treatment (P=0.61). Patients who suffered from concomitant tinnitus and dizziness responded less positively to the treatment (P=0.00). Positive family history of SSNHL seems to be negative prognostic factors in the response to treatment (P=0.02).The response to treatment was not related to the initial severity of hearing loss (P=0.68) and pattern (P=0.28). Conclusion:This study did not find any difference in the rate of hearing improvement between systemic, intratympanic, and combined corticosteroid therapy for sudden hearing loss.

Abstract
OBJECTIVES Findings regarding the benefits of fruit and vegetables (FV) on weight control are inconsistent and little is known among Chinese populations. Therefore, we examined the relationship between change in FV consumption, weight, and change in body mass index (BMI) among Chinese adults, participants of the China Health and Nutrition Survey (CHNS). STUDY DESIGN A prospective cohort study. METHODS Two waves of CHNS conducted in 2006 and 2011 were used. Continuous FV consumption increase was considered as the exposure and changes in weight and BMI as outcomes. Change in FV consumption was categorized into quintiles. Analysis of covariance and multiple linear regression models, after controlling for potential confounders such as energy intake, physical activity, and smoking, were used to describe the relationship between change in FV consumption and change in weight and BMI. RESULTS A total of 4357 participants aged 18-65 years were included in this study. The respective weight and BMI gains in male individuals were 1.81 kg and 0.73 kg/m2 in the fifth quintile of FV change relative to individuals in the first quintile (3.67 kg for weight gain and 1.48 kg/m2 for BMI gain). An increase in FV consumption by 100 g was associated with a 211 g weight loss (B = -2.11; 95% confidence interval [CI], -3.34, -0.89, P < 0.001) and a decrease in BMI by 0.94 kg/m2 (B = -0.94; 95% CI, -1.36, -0.46, P < 0.001) in men; and a 140 g weight loss (B = -0.14; 95% CI, -0.97, 0.69, P = 0.74) and a decrease in BMI by 0.29 kg/m2 BMI (B = -0.29; 95% CI, -0.63, 0.06, P = 0.11) in women. CONCLUSIONS Increase in FV consumption was associated with statistically significant weight loss and decrease in BMI among Chinese men, and, although suggested, weight loss among women was not significant. Considering the protective effect of FV on human health, increasing FV consumption in the Chinese population is recommended.

Abstract
Objective: To evaluate the effect of Penehyclidine Hydrochloride Injection on pulmonary ischemia-reperfusion in aortic dissection surgery. Methods: This study was a prospective randomized controlled trial. Between September 2015 and October 2017 in the Second Affiliated Hospital of Zhengzhou University, 60 patients with aortic dissection underwent total arch replacement surgery were randomly divided into penehyclidine hydrochloride group (group A 30 cases) and control group (group B 30 cases). Patients in group A were infused with penehyclidine hydrochloride 0.05 mg/kg after entering the operating room. Patients in group B were infused with the same dose of 0.9% normal saline. Serum tumor necrosis factor (TNF-α), interleukin-6 (IL-6), interleukin-1 (IL-1) and oxygenation index (OI) before anesthesia (T1), before cardiopulmonary bypass (T2), 1 h after cardiopulmonary bypass (T3), the end of cardiopulmonary bypass (T4), 4 h after surgery (T5) and 24 h after surgery (T6) were measured. The time of postoperative ventilator support and ICU staywas recorded. Results: At the time of T4, T5 and T6, the serum levels of TNF-α[(0.10±0.08), (0.13±0.02), (0.23±0.17) mg/L], IL-6[(0.23±0.08), (0.34±0.07), (0.54±0.17) mg/L]and IL-1[(0.62±0.14), (1.02±0.27), (1.44±0.40) mg/L]in group A were significantly lower than those in group B[(0.30±0.09), (0.51±0.19), (0.86±0.02) mg/L; (0.73±0.19), (1.33±0.13), (1.98±0.13) mg/L; (0.93±0.19), (1.43±0.66), (2.04±0.45) mg/L]. The OI was higher in group A[(446.7±267.0), (386.7±169.5), (391.7±227.9) mmHg]than that of group B[(341.2±145.2), (299.5±98.7), (275.0±127.3) mmHg](P<0.05). The time of ventilator support and ICU stay after operation was (3.6 ±1.2)d, (8.4 ± 2.0) d in group A, which was shorter than that in group B[(4.3 ± 1.8), (10.0 ± 2.2) d], and there were statistical differences between the two groups (all P<0.05). Conclusions: In total arch replacement, intravenous penehyclidine hydrochloride injection may decrease the release of serum TNF-α, IL-6, IL-1, improve oxygenation index, reduce lung ischemia-reperfusion injury, shorten the time of ventilator support and ICU stay after operation, and thus improve the prognosis of patients.

Abstract
OBJECTIVES To explore the association between obesity phenotype and the risk of hypertension among Chinese adults. STUDY DESIGN A prospective cohort study. METHODS Two waves of data were collected in 2009 and 2011 by the China Health Nutrition Survey. According to International Diabetes Federation and Chinese obesity criteria, participants were divided into four groups: metabolically healthy non-overweight/obesity (MHNO), metabolically healthy overweight/obesity (MHO), metabolically abnormal non-overweight/obesity (MANO), and metabolically abnormal overweight/obesity (MAO). Logistic regression model was performed to estimate the risk of hypertension with obesity phenotype. RESULTS Among a total of 4604 adults aged 18-65 years at baseline, 467 developed hypertension during the 2-year follow-up period. After adjusting for several potential confounders, significantly increased risks for hypertension were found for participants in MHO (odd ratio [OR]: 1.78, 95% confidence interval [CI]: 1.39-2.27), MANO (OR: 1.71, 95% CI: 1.02-2.86), and MAO (OR: 3.35, 95% CI: 2.54-4.42) group compared with the MHNO group. CONCLUSION Metabolically abnormal individuals, regardless of their body weight status, showed significantly higher risks for hypertension compared with healthy non-overweight/obese group. Furthermore, MHO individuals had significantly increased risk of incident hypertension.

Abstract
The Marangoni flow of room temperature liquid metal has recently attracted significant attention in developing advanced flexible drivers. However, most of its induction methods are limited to an external electric field. This study disclosed a new Marangoni flow phenomenon of liquid gallium induced by the gallium-copper galvanic corrosion couple. To better understand this effect, the flow field distribution of liquid gallium was modeled and quantitatively calculated. Then, the intrinsic mechanism of this flow phenomenon was interpreted, during which natural convection and temperature gradient were both excluded and the galvanic corrosion couple was identified as the main reason. In addition, this conclusion was further confirmed by combining the experimental measurement of liquid gallium surface potential and the thermocapillary effect. Moreover, the temperature condition was found to be an indirect factor to the Marangoni flow. This finding broadens the classical understanding of liquid metal surface flow, which also suggests a new way for the application of soft machines.

Abstract
Integrins, a family of heterodimeric receptors for extracellular matrix, are promising therapeutic targets for ovarian cancer, particularly high-grade serous-type (HGSOC), as they drive tumor cell attachment, migration, proliferation and survival by activating focal adhesion kinase (FAK)-dependent signaling. Owing to the potential off-target effects of FAK inhibitors, disruption of the integrin signaling axis remains to be a challenge. Here, we tackled this barrier by screening for inhibitors being functionally cooperative with small-molecule VS-6063, a phase II FAK inhibitor. From this screening, JQ1, a potent inhibitor of Myc oncogenic network, emerged as the most robust collaborator. Treatment with a combination of VS-6063 and JQ1 synergistically caused an arrest of tumor cells at the G2/M phase and a decrease in the XIAP-linked cell survival. Our subsequent mechanistic analyses indicate that this functional cooperation was strongly associated with the concomitant disruption of activation or expression of FAK and c-Myc as well as their downstream signaling through the PI3K/Akt pathway. In line with these observations, we detected a strong co-amplification or upregulation at genomic or protein level for FAK and c-Myc in a large portion of primary tumors in the TCGA or a local HGSOC patient cohort. Taken together, our results suggest that the integrin–FAK signaling axis and c-Myc synergistically drive cell proliferation, survival and oncogenic potential in HGSOC. As such, our study provides key genetic, functional and signaling bases for the small-molecule-based co-targeting of these two distinct oncogenic drivers as a new line of targeted therapy against human ovarian cancer.

Abstract
Serum hepatitis B surface antigen (HBsAg) quantification can reflect the level of HBV replication and can be used as a surrogate maker for the evaluation of infected cells. Recent studies have shown that HBsAg quantification can help to distinguish the nature history of chronic hepatitis B and predict spontaneous clearance of HBsAg and the risk of progressive liver diseases. The dynamic change in HBsAg helps to predict the therapeutic effects of interferon and nucleoside analogues and sustained virologic response, guide withdrawal, and improve and optimize the therapeutic strategy for chronic hepatitis B in clinical practice. These issues have become the hot topics in recent years. However, the cut-off values of HBsAg level in patient management and various therapeutic strategies have not been determined. This article reviews the research advances in the significance of HBsAg quantification in the natural history and optimized treatment of chronic hepatitis B.

Abstract
INTRODUCTION In China, Wuling capsule, a traditional Chinese medicine consisting of Wuling mycelia of Xylaria nigripes (Kl.) Sacc (a rare type of fungus), is used to treat major depressive disorders. A meta-analysis of randomised controlled trials was performed to compare the efficacy and safety of Wuling capsule alone with Wuling capsule-antidepressant combination in the treatment of major depressive disorders. METHODS Two assessors independently selected studies, extracted data, and conducted quality assessment and data synthesis. Standard mean difference, risk ratio (RR) ± 95% confidence interval (CI), the number needed to treat, and the number needed to harm were analysed. RESULTS A total of 12 randomised controlled trials (880 patients; mean age ± standard deviation, 39.7 ± 12.5 years; male patients, 41%) were identified, including 4 trials with Wuling capsule alone (n = 340) and 8 with Wuling capsule-antidepressant (sertraline, mianserin, mirtazapine, and paroxetine) combination (n = 540). The mean length of trial was 5.7 ± 1.3 weeks. Meta-analysis of symptomatic improvement at last-observation endpoint and study-defined response and remission revealed no significant differences between the Wuling capsule alone and antidepressant monotherapy. The Wuling capsule-antidepressant cotreatment was superior to antidepressant monotherapy in symptomatic improvement at last-observation endpoint (standard mean difference: -0.46, p = 0.001) as well as study-defined response (68.4% vs. 56.0%, RR = 1.23; p = 0.03) and remission (46.5% vs. 34.5%, RR = 1.35; p = 0.05). Wuling capsule was associated with fewer adverse drug reactions than antidepressant monotherapy. CONCLUSIONS Adjunctive Wuling capsule may augment the effects of antidepressants and may be associated with fewer adverse drug reactions. More large-scale and rigorously designed randomised controlled trials with large sample size are warranted to clarify the effectiveness of Wuling capsule for major depressive disorders.
