Prevalence and factors associated with motoric cognitive risk syndrome in community-dwelling older Chinese: a cross-sectional study. Eur J Neurol 2020; 27:1137-1145. [PMID: 32301557 DOI: 10.1111/ene.14266] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Accepted: 04/13/2020] [Indexed: 12/18/2022]
Abstract
BACKGROUND AND PURPOSE A recently proposed pre-dementia syndrome, motoric cognitive risk (MCR) syndrome, is characterized by cognitive complaints and slow gait, and increases the risk of dementia and mortality. The aim of the present study was to explore the prevalence of and factors associated with MCR syndrome in elderly community-dwelling Chinese subjects. METHODS The Ningbo Community Study on Aging recruited 953 Chinese community-dwelling participants aged ≥ 65 years from November 2016 to March 2017. Handgrip, Five-Times-Sit-to-Stand (FTSS) test time and body composition, as well as comprehensive geriatric evaluation, were measured as potentially independent factors associated with MCR syndrome. RESULTS The prevalence of MCR syndrome was 12.8% in men and 12.6% in women, and high prevalence of MCR syndrome was not associated with age or sex. Multiple logistic regression analysis by sex showed that a 1-SD increase in FTSS test time in males and females was associated with 45% (95% confidence intervals, 19-76; P < 0.01) and 20% (95% confidence intervals, 9-33; P < 0.01) higher risk of having MCR syndrome, respectively, whereas handgrip strength was inversely correlated with MCR syndrome in males [odds ratio (OR), 0.91; P = 0.02] but not females (P = 0.06). Moreover, the relationship of arm fat mass and MCR syndrome was statistically significant in both sexes (OR, 1.69-1.77), but leg fat mass was only associated with MCR syndrome (OR, 1.56; P = 0.02) in men. CONCLUSIONS Handgrip, FTSS test time and body composition were associated in a sex-specific manner with MCR syndrome in elderly community-dwelling Chinese subjects. Our results on MCR syndrome are novel and should be considered as important information in future studies.

Global coronavirus disease 2019: What has daily cumulative index taught us? Int J Antimicrob Agents 2020; 55:106001. [PMID: 32360230 PMCID: PMC7188627 DOI: 10.1016/j.ijantimicag.2020.106001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 04/21/2020] [Accepted: 04/21/2020] [Indexed: 01/12/2023]
Abstract
In addition to the absolute case number, a rapid increase in the number of COVID-19 cases within a short time results in insufficiency of healthcare systems and further negatively affects patient outcomes. This study was conducted to investigate the association between the outcomes of COVID-19 patients and daily cumulative index (DCI), which was defined as the average daily number of new cases of COVID-19 and calculated by cumulative cases/number of days between the first reported case and March 6, 2020, by country. Spearman's rank correlation analyses were conducted to evaluate the relationship between mortality, incidence, and DCI. In this study, DCI was positively correlated with incidence (adjusted risk ratio [aRR] = 1.01, 95% confidence interval [CI] = 1.00-1.02, P < 0.01). Higher correlation was observed between mortality and DCI (mortality rate: r = 0.397, P = 0.018; mortality per 1 000 000 people: r = 0.0.428, P = 0.004) than between disease incidence and DCI. DCI remained statistically significantly associated with mortality per 1 000 000 people after adjustment of Health Care Index (aRR = 1.02, 95% CI = 1.01-1.03, P < 0.001) or Healthcare Access and Quality Index (aRR = 1.02, 95% CI = 1.01-1.04, P < 0.01. Reducing DCI through strict infection control measures can help slow the number of new COVID-19 cases and further improve outcomes in COVID-19 patients.

Abstract
BACKGROUND Among adults undergoing contemporary noncardiac surgery, little is known about the frequency and timing of death and the associations between perioperative complications and mortality. We aimed to establish the frequency and timing of death and its association with perioperative complications. METHODS We conducted a prospective cohort study of patients aged 45 years and older who underwent inpatient noncardiac surgery at 28 centres in 14 countries. We monitored patients for complications until 30 days after surgery and determined the relation between these complications and 30-day mortality using a Cox proportional hazards model. RESULTS We included 40 004 patients. Of those, 715 patients (1.8%) died within 30 days of surgery. Five deaths (0.7%) occurred in the operating room, 500 deaths (69.9%) occurred after surgery during the index admission to hospital and 210 deaths (29.4%) occurred after discharge from the hospital. Eight complications were independently associated with 30-day mortality. The 3 complications with the largest attributable fractions (AF; i.e., potential proportion of deaths attributable to these complications) were major bleeding (6238 patients, 15.6%; adjusted hazard ratio [HR] 2.6, 95% confidence interval [CI] 2.2-3.1; AF 17.0%); myocardial injury after noncardiac surgery [MINS] (5191 patients, 13.0%; adjusted HR 2.2, 95% CI 1.9-2.6; AF 15.9%); and sepsis (1783 patients, 4.5%; adjusted HR 5.6, 95% CI 4.6-6.8; AF 12.0%). INTERPRETATION Among adults undergoing noncardiac surgery, 99.3% of deaths occurred after the procedure and 44.9% of deaths were associated with 3 complications: major bleeding, MINS and sepsis. Given these findings, focusing on the prevention, early identification and management of these 3 complications holds promise for reducing perioperative mortality. Study registration: ClinicalTrials.gov, no. NCT00512109.

Abstract
It has been 2 months since the first case of coronavirus disease 2019 (COVID-19) was reported in Wuhan, China. So far, COVID-19 has affected 85 403 patients in 57 countries/territories and has caused 2924 deaths in 9 countries. However, epidemiological data differ between countries. Although China had higher morbidity and mortality than other sites, the number of new daily cases in China has been lower than outside of China since 26 February 2020. The incidence ranged from 61.44 per 1 000 000 people in the Republic of Korea to 0.0002 per 1 000 000 people in India. The daily cumulative index (DCI) of COVID-19 (cumulative cases/no. of days between the first reported case and 29 February 2020) was greatest in China (1320.85), followed by the Republic of Korea (78.78), Iran (43.11) and Italy (30.62). However, the DCIs in other countries/territories were <10 per day. Several effective measures including restricting travel from China, controlling the distribution of masks, extensive investigation of COVID-19 spread, and once-daily press conferences by the government to inform and educate people were aggressively conducted in Taiwan. This is probably the reason why there was only 39 cases (as of 29 February 2020) with a DCI of 1 case per day in Taiwan, which is much lower than that of nearby countries such as the Republic of Korea and Japan. In addition, the incidence and mortality were correlated with the DCI. However, further study and continued monitoring are needed to better understand the underlying mechanism of COVID-19.

Abstract
For more than one hundred years, the surgery and non-surgery around acute necrosis pancreatitis, early and late stage-operative surgery have been strive explored, and every change in treatment concept, technological progress and breakthrough in efficacy have been gradually summarized and improved in practice.Clinical practice and basic research gradually clarified the understanding of the pathological physiological process of acute necrosis pancreatitis "two peaks of death", greatly improved the treatment of early organ failure, deepened the understanding of the diversity of pathological of local complications of acute necrosis pancreatitis, and changed the treatment mode of necrosis pancreatitis. A modern comprehensive treatment system has been gradually formed. That is, in the early stage of the disease, to prevent and control multi-organ failure as the main axis; In the later stage, to explore the best surgical intervention time as the main axis, the implementation of micro-invasive and open combination of intervention strategy, and strive to explore and improve the success rate of one-time surgery. At present, China's treatment level of acute necrosis pancreatitis in many large-capacity centers is in the forefront of the world. Through the Pancreatic Surgery Group of Surgery Society of Chinese Medical Association's tour of the Guide and a large number of academic exchanges, the level of treatment of necrosis pancreatitis in China's primary hospitals is also constantly improving. Therefore, we have reasons to believe that the day when China's acute necrotizing pancreatitis diagnosis and treatment level can break further will not be far away.

Abstract
Lung ischemia-reperfusion injury (LIRI) is a common and severe clinical complication. As the injury occurs, the pulmonary afferent nerves play an important role in regulating respiratory functions under pathophysiological conditions. The purpose of this study was to examine expression of proteinaseactivated receptor-2 (PAR2) and transient receptor potential A1 (TRPA1) in pulmonary vagal afferent nerves of LIRI and further to determine molecular mediators linking activation of PAR2 and TRPA1. A rat model of LIRI was used. Enzyme-linked immunosorbent assay (ELISA) and Western blot analysis were employed to examine pro-inflammatory cytokines (PICs, i.e., IL-1β, IL-6 and TNF-α), and the protein levels of PIC receptors, PAR2, TRPA1, and intracellular signals. In the results, IL-1β, IL-6 and TNF-α along with their receptors were amplified in afferent nerves of LIRI rats as compared with control rats. Sensory PAR2 and TRPA1 were also upregulated by LIRI. Blocking PAR2 by infusion of FSLLRY-NH2 attenuated upregulation of TRPA1 via intracellular signals, namely p38-MAPK and JNK. Moreover, blocking individual PIC receptor attenuated PAR2 and TRPA1 in pulmonary vagal afferent nerves. Our data showed specific signaling pathways leading LIRI to activation of PIC signal and activation of PAR2 and TRPA1 in pulmonary vagal afferent nerves via intracellular mediators. Targeting one or more of these signaling molecules may present opportunities to improve the abnormalities in vagal afferent nerve-mediated respiratory functions observed as LIRI occurs.

Abstract
The fungal microbiota from self-retained soil and tongue coating of 18 patients with precancerous lesions of upper gastrointestinal (PLUG) were sequenced. The diversity of α, β in and the structure of the microbial community were analyzed, and the association of them was quantified by using the Spearman rank correlation method. The richness index (1.67±2.79) and the diversity index (0.25±0.10) of the fungal microbiota from tongue coating of PLUG patients were significantly lower than those from soil (4.00±4.69; 0.99±0.18) (all P values<0.001). The relative abundance of 11 taxa from tongue coating of these PLUG patients was positively associated with that from soil (all P values<0.05).

Abstract
Objective: To investigate the changes of surgical invitations on necrotizing pancreatitis in recent 14 years by reviewing single center data. Methods: One thousand and eighty patients with necrotizing pancreatitis who received surgical invitation were involved in the study.All the patients were treated at Department of Pancreatic Surgery,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology from January 2005 to December 2018. Six hundred and seventy-eight were males and 402 were females. The median (range) age of the study patients was 45 (20-76) years.The etiology of the disease was related to cholelithiasis in 335 cases(31.02%), hyperlipemia in 302 cases(27.96%), alcohol in 226 cases(20.93%), endoscopic retrograde cholangiopancreatography in 28 cases(2.59%), pregnancy in 50 cases(4.63%), idiopathic factors in 72 cases(6.67%) and other causes in 67 cases(6.20%). The patients were divided into two groups according to the time of admission. Group 1 included 1 475 patients that admitted from January 2005 to December 2010, and group 2 included 1 539 patients that admitted from January 2011 to December 2018. The surgical interventions, morbidity and mortality of the two group were compared, and χ(2) test was used for the statistical test. Results: Two hundred and sixty-six among the 1 080 cases were treated with drainage procedures because of the pseudocyst.One hundred and seventy-five drainage procedures were performed between January 2005 and December 2018, which account for 11.87%(175 /1 475) of all patients of necrotizing pancreatitis; 91 drainage procedures were performed between January 2011 and December 2018,which account for 5.91%(91/1 539) of all patients of necrotizing pancreatitis. Eight hundred and fourteen cases received surgical intervention for infection of necrotizing tissues. Of these cases, 410 cases received percutaneous catheter drainage(PCD) of retroperitoneal fluid or residual infection. Debridement of necrotic tissues was performed on 756 cases. Of these cases, 32 cases received minimal invasive retroperitoneal debridement with/without denotes video assistant,4 cases received transluminal endoscopic debridement, 21 cases received laparoscopic debridement, and 709 cases received open laparotic debridement.Three hundred and sixty-five cases were admitted to our institute during January 2005 to December 2010, and the other 391 cases were admitted to our institute from January 2011 to December 2018. Of the first period, all debridement were performed with open laparotic procedures. Of the second period,debridement were performed with open laparotic procedures and minimal invasive procedures. The average times of surgical invasion, morbidity of principal local complications and mortality of the two periods were 1.27 and 1.34,28.22%(103/365) and 29.92%(117/346),and 6.03%(23/365) and 6.91%(27/346), respectively. Conclusions: Minimal invasive procedures can be considered for debridement in patients with necrotizing pancreatitis in some selected conditions.The involvements of minimal invasive procedures in treatment of necrotizing pancreatitis don't decrease the morbidity of principal local complications and mortality in recent years. Rational surgical procedures and appropriate surgical timing are the keys to improve the efficacy of necrotizing pancreatitis.

Abstract
Necrotizing pancreatitis is a complicated disease with multiple clinical outcomes. Although it's hard to select appropriate treatment strategies, it's still an important branch in improving the curative effect. The pathology and outcome of local complications of necrotizing pancreatitis show great diversity and individualized differences in different patients and stages of pathogenesis. Currently, a variety of treatment strategies for local complications of necrotizing pancreatitis, including minimally invasive treatment and laparotomy, can be selected. Removal of infected and necrotic tissues and adequate drainage of peripancreatic effusion are the basic principles. In clinical practice, minimally invasive and laparotomy strategies should be dialectically implemented according to the specific conditions and indications of patients. And we should avoid unilaterally emphasizing one method over the other or invariably using one method to deal with all patients' conditions. Clinical practice has proved that the choice of operation time is more decisive than the selection of debridement method to the success of treatment for local complications of necrotizing pancreatitis. As long as the operation time is appropriate, any debridement method can achieve good results. Therefore, we should avoid the overemphasis on debridement method, and ignore the significance of operation time for patients. In clinical practice, we are supposed to attach importance to the timing of intervention and selection of intervention methods according to the specific conditions of patients.

Risk of sepsis among patients with COPD treated with fixed combinations of inhaled corticosteroids and long-acting Beta2 agonists. Aging (Albany NY) 2019; 11:6863-6871. [PMID: 31509517 PMCID: PMC6756880 DOI: 10.18632/aging.102217] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Accepted: 08/14/2019] [Indexed: 11/25/2022]
Abstract
This study aimed to compare the effect of budesonide/formoterol and fluticasone/salmeterol on the risk and outcomes of sepsis in COPD patients. We conducted this study using the Taiwan National Health Insurance Research Database. We included COPD patients prescribed with budesonide/formoterol or fluticasone/salmeterol between 2004 and 2011. Outcomes including sepsis and mortality were measured. 10,267 COPD patients who received fluticasone/salmeterol and 6,844 patients who received budesonide/formoterol were enrolled into this study and then subsequence were adjusted by propensity score weighting. The incidence of sepsis was 5.74 and 4.99 per 100 person-years for the patients receiving fluticasone/salmeterol and budesonide/formoterol, respectively. Fluticasone/salmeterol was associated with higher risk of sepsis (aHR, 1.15; 95%CI, 1.07-1.24) and septic shock (aHR, 1.14; 95%CI, 1.01-1.29) than budesonide/formoterol. Besides, fluticasone/salmeterol was associated with higher risk of death (aHR, 1.090; 95%CI, 1.01-1.18) than budesonide/formoterol. Patients receiving fluticasone/salmeterol had a significant higher risk of sepsis related respiratory organ dysfunction, lower respiratory tract infection, genitourinary tract infection, bacteremia and skin infection. In conclusion, long-term treatment with budesonide/formoterol was associated with lower rates of sepsis and deaths than fluticasone/salmeterol in patients with COPD.

Abstract
Objective: To investigate the diagnostic value of endoscopic ultrasonography (EUS), Fibroscan, acoustic radiation force impulse (ARFI), and aspartate aminotransferase-to-platelet ratio (APRI) and their combination for early stage liver cirrhosis. Methods: Three hundred and twenty-two hospitalized patients who had been diagnosed with chronic viral liver disease from March 2016 to April 2018 were included. According to the clinical diagnosis, patients were divided into chronic hepatitis and the early stage liver cirrhosis group (Child-Pugh A grade). All patients were examined by Fibroscan to detect liver stiffness measurement (LSM), ARFI to detect liver virtual touch tissue quantification (VTQ) value, esophagogastroduodenoscopy and EUS to detect esophagogastric varices, laboratory and imaging examination. The index of EUS, Fibroscan, ARFI, and APRI was analyzed and the regression model was established by binary logistic regression, and the diagnostic efficacy of the above index and regression model for early stage of cirrhosis was evaluated by the area under a receiver operating characteristic curve (AUROCs). Results: An early stage cirrhosis group had significantly higher detection rate with EUS (esophagogastric varices), Fibroscan (LSM), ARFI (VTQ) and APRI than chronic hepatitis group [76.7% vs. 10.7%, 10.4 (7.8, 17.3) vs. 6.1 (5.2, 8.4) kPa, 1.71(1.48, 2.07) m/s vs. 1.25(1.14, 1.43) m/s and 0.65 (0.38, 1.15) vs. 0.38(0.26, 0.62), respectively]. The corresponding chi-square test were 140.86, Z = -9.069, Z = -9.948 and Z = -5.764, respectively and the differences were statistically significant (P < 0.01). The areas under the receiver operating characteristic curve and regression model were 0.830 (0.783 ~ 0.877), 0.793 (0.744 ~ 0.841), 0.821 (0.775 ~ 0.868), 0.686 (0.628 ~ 0.744) and 0.947 (0.925 ~ 0.969) for the diagnosis of early stage cirrhosis, respectively. Among them, the regression model of three indices (EUS, LSM and VTQ) had the largest AUROCs (0.947) and the corresponding sensitivity and specificity were 0.878 and 0.867, respectively. Conclusion: The combination of EUS, LSM and ARFI had a superior diagnostic value for early stage liver cirrhosis, and may improve the diagnosis rate and reduce the misdiagnosis rate.

Abstract
Background Latent tuberculosis infection (LTBI) is a precursor of active tuberculosis diseases and an important issue in the United States and worldwide. The association between vitamin D deficiency and LTBI is poorly understood. Methods From 2011 to 2012, the National Health and Nutrition Examination Survey (NHANES) assessed LTBI (according to tuberculin skin testing and QuantiFERON®-TB Gold In-Tube) and measured serum levels of vitamin D. We evaluated the association between LTBI and vitamin D using multivariate logistic regression models adjusted for known confounders. Results The LTBI group had a lower 25-hydroxyvitamin D [25(OH)D] level than the non-LTBI group (p=0.0012). The adjusted risk of LTBI was significantly higher among participants with serum 25(OH)D levels <12 ng/ml (adjusted OR [aOR], 2.27; 95% CI, 1.40-3.66) and 12-19 ng/ml (aOR, 1.75; 95% CI, 1.25-2.46) compared to those with a level ≥30 ng/ml. The higher risk of LTBI among the participants with serum 25(OH)D levels <12 ng/ml and 12-19 ng/ml remained unchanged in both male and summer season subgroups. Conclusions A low serum 25(OH)D level was significantly associated with the risk of LTBI in this US cohort.

Abstract
Background This study aims to compare the effects of single inhaler triple therapy comprised of inhaled corticosteroids (ICSs), long-acting β2-agonists (LABAs), and long-acting muscarinic receptor antagonists (LAMAs) with dual therapies comprised of either LABA/LAMA, ICS/LABA or separate ICS/LABA plus LAMA triple therapy. Methods The Pubmed, Embase, and Cochrane databases were searched up to October 31st 2018. Only randomized controlled trials were included in the meta-analysis. The primary outcome was the rate of moderate-to-severe chronic obstructive pulmonary disease (COPD) exacerbations. Results Seven studies fulfilling the inclusion criteria were included in the meta-analysis. Single inhaler triple therapy was associated with a significantly lower risk of COPD exacerbation compared with LABA/LAMA (rate ratio, 0.69; 95% confidence interval [CI] 0.55 to 0.87, I2=85%), and ICS/LABA (rate ratio, 0.81; 95% CI 0.73 to 0.89, I2=29%) dual therapy. Single inhaler triple therapy led to a more significant improvement in lung function and quality of life compared with LABA/LAMA and ICS/LABA dual therapy. Single inhaler triple therapy was associated with a higher risk of pneumonia compared with LABA/LAMA (risk ratio, 1.38, 95% CI 1.14 to 1.67, I2=0) dual therapy. Conclusions The use of single inhaler triple therapy for COPD patients can result in lower rates of moderate or severe exacerbations of COPD as well as improved lung function and quality of life compared with dual therapy with LABA/LAMA or ICS/LABA.

Abstract
Objective: To compare the prognostic efficiency of Lugano staging, TNM staging and Musshoff staging systems in patients with primary gastrointestinal diffuse large B-cell lymphoma(PGI-DLBCL) and investigate its clinical features and prognosis. Methods: The clinical data of 110 patients with PGI-DLBCL in Tianjin Medical University Cancer Institute and Hospital from May 2008 to August 2017 was retrospectively analyzed. The stage of lymphoma was assessed following Lugano staging, TNM staging and Musshoff staging systems respectively. The prognostic value was compared mainly according to the situation of 5-year overall survival (OS)and the influence of different clinical features on prognosis of patients was also investigated. Results: The median age of the whole study was 55(range 17-92) years old. With a median follow-up time of 36 (range 1-115) months, the median progression-free survival (PFS) was 35 (range 0-86) months, and the median overall survival was 37 (range 2-104) months. The 5-year OS rate of Lugano stagingⅠ, Ⅱ, Ⅲ and Ⅳ were 77.6%, 73.4%, 69.7%, 12.2% (χ(2)=63.395, P<0.001) respectively. The 5-year OS rate of TNM staging Ⅰ, Ⅱ, Ⅲ and Ⅳ were 77.6%, 75.9%, 25.0%, 9.3% (χ(2)=65.802, P<0.001) respectively. The 5-year OS rate of Musshoff stagingⅠ, Ⅱ, Ⅲ and Ⅳ were 84.5%, 68.4%, 25.0%, 9.3% (χ(2)=66.966, P<0.001) respectively. By Cox multiple-factors analysis, Lugano staging system was the only independent prognosis risk factor for PFS (HR=4.987, 95%CI: 1.421-17.498, P=0.009) and OS (HR=5.659, 95%CI: 1.563-20.485, P=0.008) of PGI-DLBCL. Univariated analysis revealed that the factors affecting PFS and OS of patients with PG-DLBCL include B-symptom, Eastern Cooperative Oncology Group performance status (ECOG PS), the number of extranodal lesions, serum lactate dehydrogenase (LDH), International prognostic index (IPI) score, staging and therapeutic regimen(all P values of PFS and OS<0.05). Patients with PG-DLBCL who received chemotherapy alone showed a better survival than others (PFS P=0.004; OS P<0.001); the factors affecting PFS and OS of patients with PI-DLBCL include β2-microglobulin(β2-MG), serum albumin(ALB) levels, LDH and staging (all P values of PFS and OS<0.05). Therapeutic regimen didn't affect those patients' survival (PFS P=0.661, OS P=0.720). The additional use of Rituximab failed to improve the survival of patients with PG-DLBCL and PI-DLBCL respectively (all P values of PFS and OS>0.05). Conclusions: Compared with TNM staging and Musshoff staging systems, Lugano staging system provides the best prognostic value in PFS and OS for patients with PGI-DLBCL. Accompany with B-sympto, higher ECOG PS score, more extranodal lesions, increased LDH, higher IPI score and later period are negative factors for PG-DLBCL. Increased β2-MG and LDH, lower ALB level and later period are negative factors of PI-DLBCL.

Abstract
Objective: To compare the short-term outcomes of CO₂ laser and conventional laryngeal microsurgery for vocal cord cyst. Method: Patients with vocal cord cyst were divided randomly into two groups. One group was treated with CO₂ laser (laser group) and the other underwent Micro-flap surgery(Micro-flap group). For the objective assessment, Amulti-dimensional voice program module for voice spectrum analysis was used. Result: In the laser group, there were no significant differences between the preoperative and 1 week postoperative parameters of Jitter, Shimmer and HNR(P>0.05). However,the parameters of G and VHI-10 were significantly different between the laser group and Micro-flap group(P<0.05). The objective data of the laser group pre-and post-surgery showed that the voice recovery of the laser group was significantly better than that of the Micro-flap group after 1 to 3 months of follow-up(P<0.05). But no significant differences of the parameters of G and VHI-10 was noted between the laser group and Micro-flap group(P>0.05). Conclusion: CO₂ laser laryngeal microsurgery for vocal cord cyst can significantly improve pronunciation quality.

Abstract
Objective: To understand clinical characteristics of children with pneumococcal meningitis (PM) in China and to analyze the drug sensitivity of Streptococcus pneumoniae isolates and associated impacts on death and sequelae. Methods: The clinical data, follow-up results and antimicrobial sensitivity of isolated strains of 155 children (including 98 males and 57 females, age ranged from 2 months to 15 years) with PM in 10 tertiary-grade A class hospitals of Infectious Diseases Surveillance of Pediatrics (ISPED) from 2013 to 2017 were collected and analyzed retrospectively. Patients were divided into different groups according to the following standards: ≤1 year old group,>1-3 years old group and >3 years old group according to age; death group and non-death group according to the death within 30 days after PM diagnosis; complication group and non-complication group according to the abnormal cranial imaging diagnosis; sequelae group and no-sequelae group according to the follow-up results. Bonfereoni chi-square segmentation and Kruskal-Wallis H test were used for statistical analysis. Results: There were 64 cases (41.3%) in the ≤1 year old group, 39 cases in the >1-3 years old group (25.2%), and 52 cases (33.5%) in the >3 years old group. The most common clinical manifestation was fever (151 cases, 97.4%). The mortality was 16.8% (26/155) during hospitalization. The neurological complication rate was 49.7% (77/155) during hospitalization, including the most common complication, subdural effusion and (or) empyema in 50 cases (32.3%) and hearing impairment in 6 cases. During follow-up after discharge, no death was found and focal neurological deficits were found in 47 cases (30.3%), including the frequent neurological sequelae: cognitive and mental retardation of different degree in 22 cases and hearing impairment in 14 cases (9.0%). The rate of cure and improvement on discharge was 74.8% (116/155) and the lost to follow-up rate was 8.4% (13/155). The proportions of died cases, neurological complications during hospitalization and proportions of peripheral white blood cell count <12 × 10(9)/L before admission in ≤1 year old group were significantly higher than those in >3 years old group (25.0% (16/64) vs. 5.8% (3/52), 75.0% (48/64) vs. 25.0% (13/52), 48.4% (31/64) vs. 15.4% (8/52), χ(2)=7.747, 28.767, 14.044; P=0.005, 0.000, 0.000). The proportions of headache, vomiting, neck resistance and high risk factors of purulent meningitis in >3 years old group were significantly higher than those in ≤ 1 year old group (67.3%(35/52) vs. 1.6%(1/64), 80.8% (42/52) vs. 48.4% (31/64), 69.2% (36/52) vs. 37.5% (24/64), 55.8% (29/52) vs. 14.1%(9/64), χ(2)=57.940, 12.856, 11.568, 22.656; P=0.000, 0.000, 0.001, 0.000). Streptococcus pneumoniae isolates were completely sensitive to vancomycin (100.0%, 152/152), linezolid (100.0%, 126/126), moxifloxacin (100.0%, 93/93) and ofloxacin (100.0%,41/41); highly sensitive to levofloxacin (99.3%, 142/143) and ertapenem (84.6%, 66/78); moderately sensitive to ceftriaxone (48.4%, 45/93), cefotaxime (40.0%, 44/110) and meropenem (38.0%, 38/100); less sensitive to penicillin (19.6%, 27/138) and erythromycin (4.2%, 5/120). The proportions of non-sensitive strains of penicillin (21/21) and meropenem (17/18) in the death group were significantly higher than those (90/117, 45/82) in the survived group(χ(2)=4.648 and 9.808, P=0.031 and 0.002). Conclusions: The children's PM is mainly found in infants under 3 years old in China. Death and neurological complications are more common in PM children under 1 year old. The clinical manifestations and peripheral blood inflammatory markers of PM patients under 1 year old are not typical. Fever is the most common clinical manifestation and subdural effusion and (or) empyema is the most common complication. Long-term hearing impairment is common in PM and the follow-up time must be prolonged. The dead PM cases had high in sensitive rates to penicillin and meropenem.

Abstract
Objective: To compare the efficacy of induction chemotherapy with or without autologous hematopoietic stem cell transplantation (auto-HSCT) for newly diagnosed young diffuse large B cell lymphoma (DLBCL) patients. Methods: The retrospective study was performed in 90 cases of young patients (≤60 years) with newly diagnosed DLBCL and an age-adjusted International Prognostic Index (aa-IPI) score of 2 or 3. All of them were treated with R-CHOP (32 cases, rituximab combined with CHOP), dose-intensive regimens (DA-EPOCH, Hyper CVAD/MA or ESHAP) combined with or without rituximab (25 cases), and consolidated with up-front auto-HSCT (33 cases), respectively. The efficacy and the potential predictors were evaluated. Results: ①The median age of 90 patients was 43 (18-60) years old. The median follow-up time was 42 (3-110) months. ②The 5-year progression-free survival (PFS) for R-CHOP group, dose-intensive chemotherapy group and auto-HSCT group were (33.5±10.7) %, (55.3±10.1) % and (65.8±13.6) % (P=0.012), the 5-year overall survival (OS) were (49.7±9.0) %, (61.6±10.2) % and (78.6±7.8) % (P=0.035), respectively. There was no significant difference in 5-years PFS and OS between the R-CHOP group and dose-intensive chemotherapy group (P=0.519, P=0.437) compared with that of the dose-intensive chemotherapy group, auto-HSCT group has higher 5-year PFS (P=0.042). ③ When stratified with IPI score, the high-risk group treated with auto-HSCT (26 cases) showed similar 5-years PFS and 5-years OS to those in the low-risk group with chemotherapy alone (12 cases were in R-CHOP group and 8 cases were in dose-intensive chemotherapy group) [5-years PFS were (62.3 ±14.3)%, (58.3 ±18.6)% and (51.4±18.7)%, respectively, P=0.686; 5-years OS were (69.2±13.9)%, (62.5±15.5)% and (58.3±18.6)%, respectively, P=0.592]. ④However, the high-risk group treated with auto-HSCT (26 cases) showed superior 5-years PFS (P=0.002) and 5-years OS (P=0.019) compared to the high-risk group with chemotherapy alone (20 cases were in R-CHOP group and 17 cases were in dose-intensive chemotherapy group) [5-years PFS were (62.3±14.3)%, (41.1±13.5)% and (21.9±11.6)%, respectively; 5-years OS were (69.2±13.9)%, (51.5%±14.0)% and (35.4±13.6)%, respectively]. ⑤In the univariate analysis, as a whole, patients diagnosed with GCB subtype had higher 3-years PFS (P=0.022) and 3-years OS (P=0.037) compared to non-GCB subtype patients; in subgroup analysis, patients diagnosed with GCB subtype had higher 3-years PFS and 3-years OS compared to non-GCB subtype both in R-CHOP group (P=0.030, P=0.041) and dose-intensive chemotherapy group (P=0.044, P=0.047), but not in auto-HSCT group (P=0.199, P=0.093). ⑥In the multivariate analysis, different molecular classification (GCB/non-GCB) was an independent predictor for PFS and OS both in R-CHOP group [HR=0.274 (95% CI 0.094-0.800), P=0.018; HR=0.408 (95% CI 0.164-1.015), P=0.045] and dose-intensive chemotherapy group [HR=0.423 (95% CI 0.043-1.152), P=0.048; HR=5.758 (95% CI 0.882-6.592), P=0.035]. However, there was no significant difference in PFS and OS for auto-HSCT group between GCB/non-GCB patients. Conclusion: Induction chemotherapy followed by up-front auto-HSCT has significant effect on efficacy for young and untreated patients with high risk DLBCL. Combined with induction chemotherapy followed by up-front auto-HSCT could improve the prognosis of non-GCB patients.

Abstract
Objective: A retrospective analysis of the predictive value of acoustic radiation force impulse (ARFI) elastography for esophageal varices in post-hepatitis B cirrhosis patients. Methods: 124 patients with post-hepatitis B cirrhosis who were admitted to Tianjin Second People's Hospital from August 2016 to August 2017 were selected. According to the shape of esophageal varices under gastroscopy and the risk of bleeding, patients were divided into 4 groups, none, mild, moderate and severe. In ARFI mode, the VTQ function was used to detect the VTQ values of the liver and spleen. The receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the diagnosis of esophageal varices by VTQ values of the liver and spleen. Analysis of variance was performed on the data between the groups, and χ (2) test was performed for categorical data. Results: The difference in liver VTQ values between groups were statistically significant (F = 12.623, P < 0.01). There was a statistically significant difference in VTQ values between spleens (F = 9.022, P < 0.01). The liver VTQ predicts that the AUC value of mild esophageal varices in patients with cirrhosis was 0.701 (0.575-0.827); moderate varices was 0.802 (0.701-0.902); severe varices was 0.885 (0.784-0.986). The best cutoff value was 2.235, the specificity was 97.37%, the negative predictive value was 88.10%, and the accuracy was 90.16%. The VTQ value of spleen predicts the AUC value of mild esophageal varices in patients with liver cirrhosis was 0.688 (0.539-0.798); moderate varices were 0.762 (0.651-0.873); severe varices were 0.800 (0.671-0.928). The best cutoff value was 2.885, the specificity was 84.21%, and the negative predictive value was 82.05%. Conclusion: The application of ARFI elastography in the determination of VTQ values of liver and spleen has certain predictive value for esophageal varices and it might be useful for primary screening of esophageal varices in post-hepatitis B cirrhosis patients.

Abstract
OBJECTIVES To investigate the common causes of death after drinking and the precautions for forensic identification. METHODS By reading alarm records, visiting investigations, on-site investigation transcripts, medical examination records and identification documents, the sex, age, corpse examination, toxic (drug) analysis and cause of death in 13 cases of post-drinking death were retrospectively analyzed. RESULTS In 13 cases of post-drinking abnormal death, the causes of death were mainly drowning after drinking and asphyxia induced by stomach contents reflux. However, when accompanied by injury or other toxic poisoning, competition of death causes often occured. CONCLUSIONS Combining the case and on-site inspection, a comprehensive systematic corpse examination and toxic (drug) analysis is of great significance for the forensic identification of cadavers of non-acute ethanol poisoning after drinking.

Abstract
Objective: To assess the prognostic value of (18)F-FDG PET/CT and its relationship with clinical features in newly diagnosed MM patients. Methods: A total of 123 patients with newly diagnosed MM in Tianjin Medical University Cancer Institute and Hospital from September 2008 to December 2017 were retrospectively reviewed. The overall survival (OS) and progression free survival (PFS) were estimated by Kaplan-Meier analysis and the distribution of OS and PFS were compared using log-rank test. Cox regression was used to identify the independent prognostic factors. Results: Of all 123 patients, there were 43 patients (35.0%) who had extramedullary diseases (EMD). Compared to the patients without EMD, the PFS (24.5 months vs 37.8 months, P<0.05) and OS (30.1 months vs 51.4 months, P<0.05) of the patients with EMD at diagnosed was significantly inferior. In multivariate analysis, β2-MG≥5.5 mg/L, age≥65, EMD on (18)F-FDG PET/CT and without CR at the ending of treatments were the four factors leading to poor prognosis. According to the above four factors, the patients were regrouped into low risk, medium risk and high risk groups, the significant difference existed (P<0.01) in these groups. Conclusion: (18)F-FDG PET/CT is helpful in predicting the prognosis of newly diagnosed MM patients.

Abstract
This is a preliminary report on the use of the modified Airway Management Device in 50 spontaneously breathing patients undergoing elective day care surgery. We were successful in establishing a clear airway in all 50 patients, 46 of these patients had a patent airway on the first attempt. All patients were successfully managed with the Airway Management Device throughout the surgery. Partial airway obstruction during maintenance of anaesthesia occurred in three cases requiring only minor manipulations. Our result showed that the Airway Management Device may be used as an alternative airway management in anaesthesia.

Abstract
The aim of this prospective, double-blind, randomized, placebo-controlled clinical trial was to investigate whether the administration of ketamine before induction with propofol improves its associated haemodynamic profile and laryngeal mask airway (LMA) insertion conditions. Ninety adult patients were randomly allocated to receive either ketamine 0.5 mg.kg-1 (n=30), fentanyl 1 μg.kg-1 (n=30) or normal saline (n=30), before induction of anaesthesia with propofol 2.5 mg.kg-1. Insertion of the LMA was performed 60s after injection of propofol. Arterial blood pressure and heart rate were measured before induction (baseline), immediately after induction, immediately before LMA insertion, immediately after LMA insertion and every minute for three minutes after LMA insertion. Following LMA insertion, the following six subjective endpoints were graded by a blinded anaesthestist using ordinal scales graded 1 to 3: mouth opening, gagging, swallowing, movement, laryngospasm and ease of insertion. Systolic blood pressure was significantly higher following ketamine than either fentanyl (P=0.010) or saline (P=0.0001). The median (interquartile range) summed score describing the overall insertion conditions were similar in the ketamine [median 7.0, interquartile range (6.0–8.0)] and fentanyl groups [median 7.0, interquartile range (6.0–8.0)]. Both appeared significantly better than the saline group [median 8.0, interquartile range (6.75–9.25); P=0.024]. The incidence of prolonged apnoea (>120s) was higher in the fentanyl group [23.1% (7/30)] compared with the ketamine [6.3% (2/30)] and saline groups [3.3% (1/30)]. We conclude that the addition of ketamine 0.5 mg.kg–1 improves haemo-dynamics when compared to fentanyl 1 μg.kg–1, with less prolonged apnoea, and is associated with better LMA insertion conditions than placebo (saline).

Abstract
Objective The aim of this study was to investigate the impact of COPD on the outcomes of patients with advanced chronic kidney disease (CKD). Patients and methods All patients with advanced CKD from 2000 to 2010 were identified from the Taiwanese National Health Insurance Research Database. Associations between COPD and the risk of long-term dialysis and all-cause mortality were assessed. Results A total of 33,399 advanced CKD patients were enrolled, of whom 31,536 did not have COPD (non-COPD group) and 1,863 had COPD (COPD group). The incidence of end-stage renal disease (ESRD) was higher for those with COPD than those without COPD (744.2 per 1,000 person-years vs 724.6 per 1,000 person-years, adjusted HR [aHR] 1.04; 95% CI 0.96–1.12). The cumulative incidence rates of ESRD were similar between the COPD and non-COPD groups (log-rank test, P=0.356). Overall, the patients with COPD had a higher risk of death than those without COPD (151.7 per 1,000 person-years vs 125.5 per 1,000 person-years, aHR 1.22; 95% CI 1.11–1.33). The cumulative mortality rate was higher in the COPD group than in the non-COPD group (log-rank test, P<0.001). Conclusion COPD increased the risk of mortality among the advanced CKD patients in this study, especially the elderly and male patients. In contrast, COPD did not increase the risk of ESRD among the advanced CKD patients.

Abstract
Objective:To observe the effects of sleep body posture on subjective sleepiness in patients with OSAHS.Method: We assessed the sleeping body position, the sleep structure, position specific AHI and the Epworth Sleepiness Scale (ESS) in a total of 90 patients with OSAHS. The patients were grouped according to AHI: mild OSAHS (5≤AHI<15), moderate (15≤AHI<30) and severe (AHI≥30). The polysomnography data and clinical characteristics were compared between each group.Result: There was statistically significant difference in arousal index,MinSpO2,REM% and NREM% among three groups (F value was 12.10,43.67,15.81,13.17,respectively,P<0.05). Compared with supine,the severe OSAHS group had significantly bigger changes in MinSpO2, REM% and NREM%(t value was 3.02,2.41,2.90,respectively,P<0.05). For mild-to-moderate groups,there was no correlation between the ESS and the AHI at any position(P>0.05). For severe group,the ESS was significantly correlated with L-AHI(r=0.454,P<0.01);the REM L-AHI and NREM L-AHI was also significantly correlated with ESS of severe group (r=0.522 and 0.425,P<0.01). Conclusion:The sleep body posture had significant effects on sleep structure and respiratory events in severe OSAHS group. The L-AHI was found to have a closer association with daytime sleepiness in severe OSAHS than other groups.

Palbociclib enhances radiosensitivity of hepatocellular carcinoma and cholangiocarcinoma via inhibiting ataxia telangiectasia-mutated kinase-mediated DNA damage response. Eur J Cancer 2018; 102:10-22. [PMID: 30103095 DOI: 10.1016/j.ejca.2018.07.010] [Citation(s) in RCA: 49] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 07/12/2018] [Accepted: 07/13/2018] [Indexed: 12/15/2022]
Abstract
AIM Palbociclib is an oral cyclin-dependent kinase 4/6 inhibitor, which is efficacious in treating breast cancer. Currently, there are numerous active clinical trials testing palbociclib alone or in combination with other medications for treating various types of malignancies. Here, we evaluated the anti-cancer effect of palbociclib in combination with radiation therapy (RT) for treating human hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) and addressed the molecular mechanism behind the combination therapy. METHODS Immunofluorescence staining of γH2AX or 53BP1 was used to determine the effect of palbociclib on double-strand break (DSB) repair. Clonogenic assays, sphere formation and cell death ELISA were performed to study the sensitising effect of palbociclib on radiation-induced cytotoxicity. Signal alteration in DSB repair pathways was examined by Western blot analysis. Finally, we evaluated the in vivo anti-cancer activity and the associated molecular events of the combination therapy in a preclinical HCC xenograft model. RESULTS Palbociclib affected the kinetics of DNA repair and enhanced the radiation sensitivity of HCC and CCA cells. Importantly, we found that palbociclib inhibits ataxia telangiectasia-mutated (ATM) kinase, the key upstream kinase responding to RT-induced DSBs. Furthermore, we showed that the inhibitory effect of palbociclib on RT-induced ATM kinase activation is mediated by protein phosphatase 5 (PP5). Both in vitro and in vivo investigations revealed that the inhibition of the PP5-ATM axis by palbociclib after DNA damage is responsible for the synergism between palbociclib and RT. CONCLUSION Our findings provide a novel combination strategy against liver cancer cells. Clinical trials using palbociclib as an adjuvant in RT are warranted.

Abstract
Objective: To summarize the clinical characteristics and treatment efficacy of the first reported case of a Chinese boy with stimulator of interferon genes (STING) associated vasculopathy with onset in infancy (SAVI). Methods: Sanger sequencing of the gene TMEM173 was performed based on systemic evaluation and clinical analysis of a highly suspected SAVI child admitted to Peking Union Medical College Hospital. A literature search (search terms included 'STING''SAVI''autoinflammatory diseases' and 'interferonopathy') was conducted using Chinese literature database, EMBASE and PubMed to include recently published SAVI studies (searched from January 2010 to December 2017). Results: A 14-year-old boy who had a history of chronic dry cough along with decreased activity tolerance after birth presented with growth retardation, chilblain lesions on the ear, telangiectasia of multiple skin areas and long clubbed fingers. His C-reactive protein was 21 mg/L, erythrocyte sedimentation rate was 78 mm/1h, and IgG was 22.16 g/L. The high-resolution computed tomography (HRCT) revealed interstitial lung diseases and echocardiography showed pulmonary artery hypertension, with a level of 61 mmHg (1 mmHg=0.133 kPa). Genetic mutation of TMEM173 (c.463G>A, p.V155M) was confirmed by Sanger sequencing. His activity tolerance increased to some extent after treatment with tofacitinib at a dose of 5 mg twice a day. Our review yielded 8 publications (8 English and 0 Chinese) . To date 20 cases have been reported worldwide, who mostly presented with skin and lung involvement as well as growth retardation. Conclusions: SAVI has been included within the spectrum of interferonopathy, which is a kind of autoinflammatory diseases as well. Typical clinical features include chilblain skin lesions, interstitial lung disease, growth retardation, elevated IgG levels, and increased inflammation markers. Janus kinase (JAK) inhibitors may offer benefit for SAVI patients.

Abstract
Objective: To explore the association between α-actinin-3 (ACTN3) polymorphism and muscle strength in postmenopausal women. Methods: Five hundred and ninety-eight postmenopausal women with an average of (62.9±7.0) years old in Dongcheng District of Beijing were included. The ACTN3 polymorphism including rs540874, rs618838 and rs2229456 were genotyped by Sequenom Mass Array to explore their associations with muscle strength. One hundred and sixty-three of them were trained with regular Tai chi movement while 271 were administered with elemental calcium 600 mg/d combined with Vitamin D 800 U/d or calcitriol 0.25 μg/d for 2 years. Association between changes of muscle strength and ACTN3 polymorphism were analyzed. Results: The rs540874 genotypes were found to be significantly associated with chair stand test[GG (9.02±3.85) s vs GA (9.27±4.14) s vs AA (9.68±5.00) s, P=0.015]. Right grip strength in women with G allele were likely to be higher compared with A allele, but it was not statistically significant (P=0.056). Multiple linear regression showed that the chair stand test of AA genotype was statistically longer than that of GG and GA genotype (β=2.639, 95% CI: 1.632-4.646, P=0.010). The associations between rs618838, rs2229456 genotypes and muscle strength of both lower and upper limbs were not significant (all P>0.05). In addition, muscle strength of lower limbs of patients with rs540874 genotyped with G allele, rs618838 genotyped with C allele and rs2229456 genotyped with A allele increased significantly after enhanced exercise and vitamin D supplementation (all P<0.05). Conclusions: The rs540874 polymorphism of ACTN3 gene was associated with the muscle function of lower limb in postmenopausal women. The improvement of muscle strength after intervention were possibly correlated with rs540874, rs618838 and rs2229456 polymorphisms.

Abstract
Objectives This study aimed to compare the effects of angiotensin-converting-enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) on the risk of pneumonia and severe exacerbations in patients with COPD. Patients and methods All patients with COPD who used ACEis and ARBs for >90 days between 2000 and 2005 were recruited. Pairwise matching (1:1) of the ACEi and ARB groups resulted in two similar subgroups, with 6,226 patients in each. The primary outcomes were pneumonia and COPD exacerbations, and the secondary outcome was death. Results During the follow-up period, the incidence of pneumonia was 7.20 per 100 person-years in the ACEi group and 5.89 per 100 person-years in the ARB group. The ACEi group had a higher risk of pneumonia (adjusted hazard ratio [aHR], 1.22; 95% CI, 1.15–1.29) than the ARB group. The incidence of severe exacerbations was 0.65 per person-year for the patients receiving ACEis and 0.52 per person-year for those receiving ARBs. The patients receiving ACEis had a higher risk of severe exacerbations (aHR, 1.19; 95% CI, 1.16–1.21) than those receiving ARBs. Similar trends were noted in terms of severe exacerbations requiring hospitalization (aHR, 1.24; 95% CI, 1.21–1.28) or emergency department visits (aHR, 1.16; 95% CI, 1.13–1.18), pneumonia requiring mechanical ventilation (aHR, 1.35; 95% CI, 1.24–1.47), and mortality (aHR, 1.33; 95% CI, 1.26–1.42). Conclusion ARBs were associated with lower rates of pneumonia, severe pneumonia, and mortality than ACEis in patients with COPD.

Abstract
Objective: To evaluate the effectiveness of mumps prevention and control after implementation of two doses mumps-containing combined vaccine (MuCV) policy by analyzing epidemiological characteristics of mumps and mumps antibody levels in general population. Methods: We obtained data on cases of mumps reported during 2004-2015 from National Notifiable Diseases Reporting System (NNDRS). Descriptive analysis methods were used to describe the epidemiological characteristics of mumps during 2004-2015. MuCV immunization information from 2005 to 2015 was obtained from the immunization information management system in Shandong Province. Antibody data of mumps in healthy people were from a cross-sectional survey according to the principle of stratified random sampling from 0 to 60 years old healthy people in 2015. Commercial ELISA kits were used to detect and quantify human IgG antibodies against mumps virus in sera, and the results were analyzed statistically. Results: The average incidence of mumps from 2004 to 2015 was 11.43/100 000 in Shandong. The incidence of mumps in the central region (14.64/100 000) was higher than that in the eastern and western regions (11.14/100 000, 11.33/100 000). The incidence of mumps was still high in 2009-2013 (stage of one-dose MuCV free, 16.07/100 000) with the highest incidence of 25.33/100 000 and 24.45/100 000 occurred in 2012 and 2013 and the cases were mainly 6 to 9 years old group (172.67/100 000). Since the second dose MuCV was introduced into NIP for 6 years old children in May 2013 in Shandong, the incidence of mump decreased significantly in 2014-2015 (7.81/100 000), especially in children of 6-8 years old who were vaccinated with two doses of MuCV (2009-2013 was 114.02/100 000; 2014-2015 was 45.66/100 000) and lower than 3-5 years old vaccinated one doses of MuCV. A total of 1 785 serum samples were collected from the healthy population, the average seroprevalence was 80.62% and Geometric Mean Concentration (GMC) was 38.11 IU/ml (95%CI: 37.03-39.19 IU/ml) . There was no significant difference about seroprevalence in different regions, while the GMC in middle region was significantly higher compared to east and west region. The prevalence and GMC in children aged 19 months-2 years and 3-5 years old who received one dose of MuCV were significantly higher than those of <19 months old children. The GMC (46.88 IU/ml, 95%CI: 39.43-55.74 IU/ml) in children aged 6-9 years old who received the two doses MuCV was significantly higher than that of aged 3-5 years old children (31.71 IU/ml, 95%CI: 27.23-36.93 IU/ml). Conclusion: The incidence of mumps in Shandong was still at a high level in spite of coverage one doses MuCV to children. Compared with the period of the 1 dose MuCV immunization strategy, the incidence the groups coverage two doses MuCV was significantly reduced and lower the groups coverage one dose MuCV, but the prevalence and GMC were higher than that of the groups coverage one dose MuCV.

Abstract
Gallium nitride (GaN) nanowires (NWs) hold technological significance as functional components in emergent nano-piezotronics. However, the examination of their mechanical responses, especially the mechanistic understanding of behavior beyond elasticity (at failure) remains limited due to the constraints of in situ experimentation. We therefore performed simulations of the molecular dynamics (MD) of the mechanical behavior of [Formula: see text]-oriented GaN NWs subjected to tension or compression loading until failure. The mechanical properties and critical deformation processes are characterized in relation to NW sizes and loading conditions. Detailed examinations revealed that the failure mechanisms are size-dependent and controlled by the dislocation mobility on shuffle-set pyramidal planes. The size dependence of the elastic behavior is also examined in terms of the surface structure determined modification of Young's modulus. In addition, a comparison with c-axis NWs is made to show how size-effect trends vary with the growth orientation of NWs.

Abstract
For decades, dental schools in the United States have endured a significant faculty shortage. Studies have determined that the top 2 sources of dental faculty are advanced education programs and private practice. Those who have completed both DDS and PhD training are considered prime candidates for dental faculty positions. However, there is no national database to track those trainees and no evidence to indicate that they entered academia upon graduation. The objective of this study was to assess outcomes of dental school-affiliated oral sciences PhD program enrollment, graduates, and placement between 1994 and 2016. Using the American Dental Association annual survey of advanced dental education programs not accredited by the Commission on Dental Accreditation and data obtained from 22 oral sciences PhD programs, we assessed student demographics, enrollment, graduation, and placement. Based on the data provided by program directors, the average new enrollment was 33, and graduation was 26 per year. A total of 605 graduated; 39 did not complete; and 168 were still in training. Among those 605 graduates, 211 were faculty in U.S. academic institutions, and 77 were faculty in foreign institutions. Given that vacant budgeted full-time faculty positions averaged 257 per year during this period, graduates from those oral sciences PhD programs who entered academia in the United States would have filled 9 (3.6%) vacant faculty positions per year. Therefore, PhD programs have consistently generated only a small pipeline of dental school faculty. Better mentoring to retain talent in academia is necessary. Stronger support and creative funding plans are essential to sustain the PhD program. Furthermore, the oral sciences PhD program database should be established and maintained by dental professional organizations to allow assessments of training models, trends of enrollment, graduation, and placement outcomes.

Abstract
Objective:To evaluate the difference of accessing pediatric sleep symptoms and living qualities between 3 diagnostic criteria: American Thoracic Society (ATS), International Classification of Sleep Disorder (ICSD-3), domestic Urumqi criterion (Draft); To investigate the relationship of PSG parameters and quality of life scale OSA-18. Method:Children with snoring who received PSG in Capital Medical University Beijing Tongren Hospital were recruited from Jan 2016 to Apr 2017. Subjects were diagnosed and grouped to SS, ICSD, ATS&ICSD (ATS&ICSD1, ATS&ICSD2) according to 3 criteria: ATS (AHI>5 or OAI>1), ICSD-3 (OAHI≥1) and Urumqi (AHI>5 or OAI>1, with LSaO₂<92%). Subjects' height, weight as well as quality of life scale OSA-18 were recorded. Result:Five hundred and fifteen children were finally included (Male: 350 cases, Female: 165 cases). There were 315, 70 and 130 children in group SS, ICSD, ATS&ICSD respectively. Weights and BMI of ICSD and ATS&ICSD were significantly higher than those of SS (P<0.05), and dysplasia scale of ATS&ICSD was higher than SS (P<0.05); after adjusting height, weight and BMI, sub-scores of sleep disorder were statistically different between 3 groups (P<0.05). Numbers and indexes of respiratory events other than central apneas and hypopneas in group SS, ICSD and ATS&ICSD were increased sequentially and statistically different (P<0.05); numbers and indexes of respiratory events other than mixed apneas in ATS&ICSD2 were significantly higher than that of ATS&ICSD1 (P<0.05). Conclusion:OAHI≥1/h combined with LSaO₂<92% should be used as pediatric OSAHS diagnostic criterion.

Abstract
BACKGROUND Ambulatory surgery has recently gain popularity, as it is a good method of optimizinghospital resources utilization. To support ambulatory surgery, anaesthetic goals nowrevolve around patients' early recovery with minimal pain and nausea, expedientdischarge home and prompt resumption of activities of daily living. In this study, weevaluated the effect of a single pre-induction dose of dexmedetomidine on anaestheticrequirements, postoperative pain and clinical recovery after ambulatory ureteroscopy andureteric stenting under general anaesthesia. METHODS Sixty patients were randomised to receive IV dexmedetomidine 0.5 μg.kg-1 (Group DEX, n = 30) or IV saline (Group P, n = 30). General anaesthesia was maintained with Sevoflurane: oxygen: air, titrated to BIS 40-60. Pain intensity, sedation, rescue analgesics, nausea/vomiting and resumption of daily activities were recorded at 1 h, and postoperative day (POD) 1-5. RESULTS Group DEX patients had significant reduction in sevoflurane minimum alveolar concentration (MAC), mean (SD) DEX vs. Placebo 0.6 (0.2) vs. 0.9 (0.1), p = 0.037; reduced postoperative resting pain at 1 h (VAS 0-10) (mean (SD) 1.00 (1.84) vs. 2.63 (2.78), p = 0.004), POD 1 (mean (SD) 1.50 (1.48) vs. 2.87 (2.72), p = 0.002), POD 2 (0.53 (0.97) vs. 1.73 (1.96), p = 0.001) and POD 3 (0.30 (0.75) vs. 0.89 (1.49), p = 0.001). DEX patients also had less pain on movement POD 1 (3.00 (2.12) vs. 4.30 (3.10), p = 0.043) and POD 2 (2.10 (1.98) vs. 3.10 (2.46), p = 0.040), with higher resumption of daily activities by 48 h compared to placebo, 87% vs. 63%, p = 0.04. CONCLUSIONS We conclude that a single dose of dexmedetomidine was a useful adjuvant in reducing MAC and postoperative pain (at 1 h and POD 1-3), facilitating faster return to daily activities by 48 h.

Abstract
Objective: To study tumors and fertility outcomes after fertility-sparing surgical treatment with borderline ovarian tumors (BOT). Methods: One hundred and nineteen patients with BOT enrolled from 3 hospitals between January 2004 and January 2017 were analysed retrospectively.The clinical data and follow-up results were obtained and analyzed. Results: Among the 119 BOT patients, 55 patients underwent fertility-sparing surgery.The median age was 43 years (interquartile range: 15-80 years). There were 103 patients (86.55%) in stage Ⅰ, and 16 patients (13.45%) in stage Ⅱ and above.The median follow up time was 68 months (range: 4-155). (1)Tumor outcomes: 13 patients recurred and 3 patients died.Progression free survival (PFS) and the overall survival rate had no significant difference between the two groups (85.45% vs 92.19% P=0.309, 96.4% vs 98.4% P=0.492). PFS was related to FIGO stage, invasive implantation and chemotherapy by univariate analysis (P<0.05). The multivariate Cox regression model analysis showed that FIGO stage and invasive implantation were independent prognostic factors for PFS (P<0.05). (2) Pregnancy outcomes: 28 patients had a planned for pregnancy in fertility-sparing group, with 13 (46.43%) of them were pregnancy. Conclusions: FIGO stage and invasive implantation were the important factors of prognosis.Fertility-sparing surgery is safe and feasible to preserve the fertility of young patients.

Abstract
Objective:IgG4-related disease is a newly recognized systemic disease, and its elucidation is progressing. However, little is known about its sinonasal manifestations.The aim of this study was to assess the olfaction of patients with IgG4-related disease.Method:Twenty-two patients with IgG4-related disease underwent the odor stick identification test to measure olfactory function.We analyzed the clinical features, including serum IgG4 levels, involved organs, and sinonasal computed tomography scores to explore the etiology of olfactory dysfunction.Result:Eleven patients with IgG4-related disease were found to have olfactory dysfunction. There were no differences in the clinical features between the olfactory dysfunction group and the normal group.Conclusion:There were no correlation between olfactory function and serum IgG4 level, involved organs or sinonasal computed tomography scores.We found that the prevalence of olfactory dysfunction was high in patients with IgG4-related disease and that it could be reversed.Olfactory dysfunction appears to be a novel important manifestation of IgG4-related disease.

Abstract
Background There is conflicting information regarding the effects of selective and nonselective beta-blocker treatment in patients with COPD. Participants and methods This nested case–control study used the Taiwan National Health Insurance Research Database. We included COPD patients who used inhalation steroid and beta-blockers between 1998 and 2010. From this cohort, there were 16,067 patients with severe exacerbations included in the analysis and 55,970 controls matched on age, sex, COPD diagnosis year, and beta-blockers treatment duration by risk set sampling. Results For the selective beta-blocker users, the current users had a lower risk of severe exacerbations than the nonusers (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.85–0.96). In contrast, for the nonselective beta-blocker users, the current users had a higher risk of severe acute exacerbations than the nonusers (OR, 1.21; 95% CI, 1.14–1.27). A higher risk of severe exacerbation during increasing mean daily dose or within about the initial 300 days was found in nonselective beta-blockers, but not in selective beta-blockers. One selective beta-blocker, betaxolol, had a significantly lower risk of severe exacerbations (OR, 0.75; 95% CI, 0.60–0.95). Two nonselective beta-blockers (labetalol and propranolol) were associated with a significantly higher risk of exacerbations (OR, 1.49; 95% CI, 1.32–1.67 for labetalol; OR, 1.16; 95% CI, 1.10–1.23 for propranolol). Conclusion Selective beta-blockers can be cautiously prescribed for patients with COPD and cardiovascular disease (CVD), however, nonselective beta-blockers should not be prescribed for patients with COPD. Betaxolol may be the preferred choice of suitable selective beta-blocker for patients with COPD, however, labetalol and propranolol should be avoided for patients with COPD.
