Abstract
Objective: To evaluate the efficacy of 23 valent pneumococcal polysaccharide vaccine (PPV23) inoculation against community-acquired pneumonia (CAP) among the elderly aged 60 years old and above in Shanghai. Methods: A prospective cohort study was conducted using a stratified random sampling from October 2013, in which 1 214 and 2 387 elderly people aged 60 and above were selected as the inoculation group and control group, respectively. And a unified questionnaire was used to investigate the basic information of the subjects in the inoculation group and the control group. From October 2013 to December 2018, the subjects were followed up at home or by telephone for a total of 20 times, mainly for whether they had CAP during the observation period. Multivariate logistic regression model was used to calculate RR and 95%CI of CAP incidence between inoculation group and control group for comparing. Results: There were 556 males (45.8%) in the inoculation group and 1 012 males (42.4%) in the control group. And the incidence density of CAP in the inoculation group was lower than that of the control group (0.848/100 person-years vs. 1.452/100 person-years), and the vaccine protection rate was 41.6%, with a statistically significant difference [RR (95%CI)= 0.584 (0.428-0.790), P<0.001]. After adjusting for age, RR (95%CI) was 0.699 (0.507-0.956), and the difference was still statistically significant (P=0.025).Further stratified analysis showed that the vaccine protective rates of PPV23 in the 60-69 year-old group, the 70-79 year-old group and the ≥80 year-old group were 36.7%, 21.6% and 26.0%, respectively, but only in the 60-69 year-old group showed statistical difference (RR=0.633, 95%CI=0.399-0.990, P=0.045). Conclusion: To a certain extent, the incidence of CAP can be reduced by inoculation of PPV23 in elderly population aged 60 and above in Shanghai, and it should be further recommended in elderly population of low age.

Abstract
Objective: To understand the project personnel's attitude towards the 23-valent pneumococcal polysaccharide vaccination program for the elderly in Shanghai and its conversion to routine vaccination and to explore its influential factors, so as to provide reference for the further development of the program. Methods: In 2016, a one-to-one questionnaire survey was conducted among the people involved in the project in the 9 districts of Shanghai and the data of demographic characteristics, cognition of pneumococcal pneumonia and PPV23, evaluation of the project, support rate of the project and its conversion to routine vaccination of the project personnel were collected. Results: Among the 2005 respondents, 28.6% (574 persons) of them were male, 85.5% (1 714 persons) of them supported the free vaccination for the elderly, and 69.5% of them (1 394 persons) supported the routine vaccination. For the 23-valent pneumococcal polysaccharide vaccination program, people under 55 years old, in Qingpu District, with poor cognition of pneumonia and 23-valent pneumococcal polysaccharide vaccine (PPV23) or having lower evaluation of the project's scientificity or enforceability had lower support rate than others, and the OR (95%CI) were 0.38 (0.19-0.75), 0.21 (0.10-0.43), 0.16 (0.06-0.41) and 0.26 (0.10-0.69). People believing that the elderly were susceptible to pneumococcal pneumonia and PPV23 was safe and reliable, and those who were willing to vaccinate the elderly at home had higher support rate, and the OR (95%CI) were 2.30 (1.18-4.47), 2.84 (1.62-4.69) and 5.60 (3.74-8.38). For the program's conversion to routine vaccination, people under 35 years old, in Qingpu District, in the vaccination clinic, and those believing that the project was not scientific and difficult to implement had low support rate, and the OR (95%CI) were 0.56 (0.32-0.98), 0.48 (0.26-0.89), 0.26 (0.12-0.59), 0.58 (0.42-0.79) and 0.50 (0.30-0.81); people with technical secondary school or senior school, in Jiading, Putuo or Minhang District, believing that PPV23 was effective in the prevention of pneumococcal pneumonia in the elderly, and those who were willing to vaccinate the elderly with PPV23 had higher support rate, and the OR (95%CI) were 1.63 (1.11-2.39), 2.28 (1.71-3.03), 1.69 (1.25-2.28) and 4.10 (2.86-5.88). Conclusion: The support rate of pneumococcal vaccination project for the elderly in Shanghai needs to be improved, especially its conversion to the routine vaccination.

Abstract
Objective: To evaluate the safety of 23 Valent Pneumococcal Polysaccharide Vaccine (PPV23) among eldly people aged 60 and above in Shanghai. Methods: A total of 1 310 660 monitoring data of adverse events following immunization (AEFI) of PPV23 among people aged 60 and above were collected through the National AEFI Surveillance System from September 14, 2013 to December 31, 2017 in Shanghai. And the descriptive epidemiological methods were used for analysis. Results: 433 cases of AEFI were reported from September 14, 2013 to December 31, 2017, with the incidence rate of AEFI was 33.04/100 000 doses. The general reactions were reported as 392 cases (90.53%), with 17 cases of abnormal reactions (3.93%), 23 cases of coincidences (5.31%) and 1 case of psychogenic reactions (0.23%). The reported incidence rates of general reactions and abnormal reactions of free PPV23 inoculation among elderly people in urban areas were 41.31 per 100 000 doses and 1.91/100 000 doses, respectively, which were higher than those in suburban areas (24.18/100 000 doses, 1.32/100 000 doses) and exurban areas (27.84/100 000 doses, 0.59/100 000 doses). The reported incidence rate of general reaction in females (35.38/100 000 doses) was higher than that in males (24.06/100 000 doses), and the reported incidence rate of abnormal reaction in males (1.58/100 000 doses) was higher than that in females (1.03/100 000 doses). The reported incidence rates of general and abnormal reactions were the highest in 60-64 years old group (62.65/100 000 doses and 4.87/100 000 doses, respectively). In addition, all patients with general reactions or abnormal reactions were better or cured. Conclusion: PPV23 vaccination is safe among people aged 60 and above in Shanghai.

Abstract
Objective: To investigate the predictive factors of poor prognosis in children with acute kidney injury (AKI) treated with renal replacement therapy (RRT). Methods: In this retrospective case-control study, the clinical data were collected from 134 pediatric patients (82 male, 52 female) with AKI treated with RRT in six tertiary hospitals from May 2015 to June 2018. According to the serum creatinine level at discharge, the patients were divided into the favorable outcome group and unfavorable outcome group. The data of sex, age, primary diseases, AKI stage, time from diagnosis of AKI to start of RRT (h) and whether to start RRT within 24 hours, urine volume and complications between the two groups were compared. Continuous variables were compared by t test and Mann-Whitney U test, and percentage or proportions were compared by Chi square test. The predictive factors of adverse prognosis were analyzed by using univariate and unconditional binary logistic regression analysis. Results: The average age of the 134 AKI patients was (6±4) years. There were 114 patients (85.0%) in the favorable outcome group and 20 patients (15.0%) in the unfavorable outcome group. No statistically significant differences were found between the two groups in terms of sex (χ(2)=2.596, P=0.107), age (t=0.718, P=0.474), primary disease (χ(2)=2.076, P=0.722), AKI stage (χ(2)=0.004, P=0.998), time from diagnosis of AKI to start RRT (h) (P=0.745), whether to start RRT within 24 hours (χ(2)=0.016, P=0.899), urine volume (χ(2)=3.118, P=0.374), fluid overload (χ(2)=0.014, P=0.905), multiple organ dysfunction syndrome (MODS) (χ(2)=2.972, P=0.085), acidosis (χ(2)=3.204, P=0.073), hyperkalemia (χ(2)=2.829, P=0.093), the level of blood urea nitrogen (t=1.351, P=0.179) and serum creatinine (P=0.901) at the beginning of RRT. In the unfavorable outcome group, the proportion of patients with mechanical ventilation (45.0% (9/20) vs. 12.3% (14/114), χ(2)=12.811, P<0.01) and the incidence of extra organ injury (≥3) (30.0% (6/20) vs. 10.5% (12/114), χ(2)=6.365, P=0.041) were higher than those in the favorable outcome group. Logistic regression analysis showed that mechanical ventilation (OR=12.540, 95%CI: 3.376-46.577, P<0.01) and hyperkalemia (OR=4.611, 95%CI: 1.265-16.805, P=0.021) were the predictive factors of poor prognosis in patients with AKI treated with RRT. Conclusion: Mechanical ventilation and hyperkalemia may predict a poor prognosis in AKI patients treated with RRT.

Abstract
OBJECTIVE The aim of this study is to evaluate the feasibility and aesthetic results when comparing two cosmetic approaches that were employed in parotidectomy according to the tumour location with the traditional Blair approach. DESIGN Retrospective study. SETTING Tertiary Referral Centre. PATIENTS Seventy-six patients were included in the study. RESULTS The degree of satisfaction with the cosmetic incision approach was significantly higher than that with the traditional Blair approach. The incidence of transient facial paralysis and salivary fistula were not statistically significant when compared with those in the traditional incision in 6-month follow-up post-operatively. DISCUSSION Conventional parotidectomy using the traditional Blair incision (or its modification) usually leaves a visible scar in this region, which can have major adverse impacts on the social or psychological well-being of an individual. To achieve better aesthetic results, according to the location of the benign parotid tumour, two formal cosmetic approach incisions could be performed in parotidectomy, which was superior to the traditional Blair incision. The authors propose that these two cosmetic approaches for parotidectomy can be both technically feasible and safe.

Abstract
Despite the rocketing rise in power conversion efficiencies (PCEs), the performance of perovskite solar cells (PSCs) is still limited by the carrier transfer loss at the interface between perovskite (PVSK) absorbers and charge transporting layers. Here, we propose a novel in situ passivation strategy by using [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) to improve the charge dynamics at the rear PVSK/CTL interface in the n-i-p structure device. A pre-deposited PCBM-doped PbI2 layer is redissolved during PVSK deposition in our routine, establishing a bottom-up PCBM gradient that is facile for charge extraction. Meanwhile, the surface defects are in situ-passivated via PCBM-PVSK interaction, which substantially suppresses the trap-assisted recombination at the rear interface. Due to the synergistic effect of charge-extraction promotion and trap passivation, the fabricated PSCs deliver a champion PCE of 20.10% with attenuated hysteresis and improved long-term stability, much higher than the 18.39% of the reference devices. Our work demonstrates a promising interfacial engineering strategy for further improving the performance of PSCs.

Abstract
Acetylation is an important, reversible posttranslational modification to a protein. In a previous study, we found that there were a large number of acetylated sites in various nutrient storage proteins of the silkworm haemolymph. In this study, we confirmed that acetylation can affect the stability of nutrient storage protein Bombyx mori apolipophorin-III (BmApoLp-III). First, the expression of BmApoLp-III could be upregulated when BmN cells were treated with the deacetylase inhibitor panobinostat (LBH589); similarly, the expression was downregulated when the cells were treated with the acetylase inhibitor C646. Furthermore, the increase in acetylation by LBH589 could inhibit the degradation and improve the accumulation of BmApoLp-III in BmN cells treated with cycloheximide and MG132 respectively. Moreover, we found that an increase in acetylation could decrease the ubiquitination of BmApoLp-III and vice versa; therefore, we predicted that acetylation could improve the stability of BmApoLp-III by competing for ubiquitination and inhibiting the protein degradation pathway mediated by ubiquitin. Additionally, BmApoLp-III had an antiapoptosis function that increased after LBH589 treatment, which might have been due to the improved protein stability after acetylation. These results have laid the foundation for further study on the mechanism of acetylation in regulating the storage and utilization of silkworm nutrition.

Abstract
Over the years, ad-hoc procedures were used for designing SNP arrays, but the procedures and strategies varied considerably case by case. Recently, a multiple-objective, local optimization (MOLO) algorithm was proposed to select SNPs for SNP arrays, which maximizes the adjusted SNP information (E score) under multiple constraints, e.g. on MAF, uniformness of SNP locations (U score), the inclusion of obligatory SNPs and the number and size of gaps. In the MOLO, each chromosome is split into equally spaced segments and local optima are selected as the SNPs having the highest adjusted E score within each segment, conditional on the presence of obligatory SNPs. The computation of the adjusted E score, however, is empirical, and it does not scale well between the uniformness of SNP locations and SNP informativeness. In addition, the MOLO objective function does not accommodate the selection of uniformly distributed SNPs. In the present study, we proposed a unified local function for optimally selecting SNPs, as an amendment to the MOLO algorithm. This new local function takes scalable weights between the uniformness and informativeness of SNPs, which allows the selection of SNPs under varied scenarios. The results showed that the weighting between the U and the E scores led to a higher imputation concordance rate than the U score or E score alone. The results from the evaluation of six commercial bovine SNP chips further confirmed this conclusion.

Abstract
Few studies focused on the relationship between hepatitis B virus (HBV) infection and classical Hodgkin lymphoma (cHL). This study was to evaluate the impact of HBV infection on the treatment outcome and survival of cHL patients. Clinical data of 352 cHL patients treated with ABVD regimen (doxorubicin, bleomycin, vincristine and dacarbazine) between January 2002 and January 2018 were retrospectively collected. According to HBV infection status, the patients were divided into three groups: with HBV infection [hepatitis B surface antigen (HBsAg)-positive], with past HBV infection [HBsAg-negative but anti-hepatitis B core antigen (anti-HBc)-positive], and without HBV infection (HBsAg-negative and anti-HBc-negative). The incidence of HBV infection and past HBV infection in cHL patients were 7.4% (26/352) and 16.5% (58/352), respectively. The median age of patients without HBV infection was lower than those in other two groups (p<0.001). The complete remission rates after first-line therapy were different among 3 groups (65.4% for the group with HBV infection, 87.9% for the group with past HBV infection, and 76.1% for the group without HBV infection, respectively, p=0.049). After a median follow-up of 34.6 months, the 3-year progression-free survival rates for the three groups were 69%, 74% and 80%, respectively (p=0.566) and the 3-year overall survival rates were 72%, 91% and 87%, respectively (p=0.096). No HBV reactivation was observed during chemotherapy among 3 groups, but 1 patient in the group with HBV infection experienced delayed HBV reactivation when prophylactic entecavir was discontinued 12 months after the last cycle of chemotherapy. HBV infection status did not affect the clinical outcome and prognosis of cHL patients, especially in the era of prophylactic antiviral therapy.

Abstract
OBJECTIVE To investigate the effect of long non-coding RNA URHC on the proliferation, apoptosis and invasion of colorectal cancer cells. PATIENTS AND METHODS The expression of lncRNA-URHC in tissues and cells was tested by Real-time quantitative PCR. The expression of lncRNA-URHC was down-regulated by RNA interference (siRNA). The Real-time quantitative polymerase chain reaction (PCR) method was used to detect the interference efficiency. Cell counting kit-8 (CCK-8), flow cytometry, and transwell were used to detect the effect of lncRNA-URHC on the proliferation, apoptosis and invasion of colorectal cancer cells. The effect of lncRNA-URHC on epithelial-mesenchymal transition (EMT)-related markers was detected by Western blot. RESULTS LncRNA-URHC expression was significantly increased in colorectal cancer cells compared with normal cells, and the expression of lncRNA-URHC in colorectal cancer cells was higher than that in the normal cell. After down-regulated the expression of lncRNA-URHC, the proliferation and invasion of colorectal cancer cells were decreased, while cells apoptosis was promoted. Down-regulation of lncRNA-URHC could enhance the expression of E-cadherin and reduce the expression of N-cadherin, vimentin and snail. CONCLUSIONS Down-regulation of lncRNA-URHC can inhibit the progression of colorectal cancer.

Abstract
Thin-film thermoelectrics (TEs) with unique advantages have triggered great interest in thermal management and energy harvesting technology for ambient temperature microscale systems. Although they have exhibited a good prospect, their unsatisfactory performances still seriously hamper their widespread application. Tailoring the porous structure has been demonstrated to be a facile strategy to significantly reduce thermal conductivity and enhance the figure of merit (ZT) of bulk TE materials; however, it is challenging for thin-film TEs. Here, the nanoporous Bi2Te3 thin films with faceted pore shapes and various porosities, pore sizes, and pore intervals are carefully designed and fabricated by evacuating the over-stoichiometry Te atoms. The dependence of the carrier mobility and lattice thermal conductivity on the pore characteristics is investigated. In the case of the pore interval longer than the electron mean free path, the porous structure greatly reduces the lattice thermal conductivity without affecting the electrical conductivity obviously. Phonon specular backscattering that is highly related to the pore characteristics is suggested to be mainly responsible for thermal conductivity reduction, resulting in ∼60% enhancement in ZT at room temperature, that is, from ∼0.42 for the dense film to ∼0.67 for the nanoporous film. The enhanced ZT value is comparable to that of commercial bulk TEs and can be further improved by optimizing the carrier concentrations. This work provides a general approach to fabricate high-performance chalcogenide TE thin-film materials.

Abstract
BACKGROUND The economic and clinical benefits of laparoscopic colorectal surgery are proven, yet may be underutilized in appropriate cases, especially in the elderly. Since the elderly constitute the greatest colorectal surgical volume, our goal was to identify trends in utilization and impact of laparoscopy in this cohort. METHODS A national review of elective inpatient colorectal resections from the Premier Inpatient Database between 2010 and 2015 was performed. Patients were included if elderly (≥ 65 years), then grouped into open or laparoscopic procedures. The main outcome measures were trends in utilization by approach and total costs for the episode of care, length of stay (LOS), readmission, and complications by approach in the elderly. Multivariable regression models controlled for differences across platforms, adjusting for patient demographic, comorbidities and hospital characteristics. RESULTS In 70,655 elderly patients evaluated, laparoscopic adoption remained lower than open throughout the study period. Rates increased until 2013, then declined, with increasing rates of open surgery. Laparoscopy was associated with significantly lower mean total costs ($4012 less/case), complications and readmissions (36% and 33% less, respectively), and shorter LOS (2.6 less days) than open cases (all p < 0.0001). When complications occurred, they were less severe and the readmission episodes were less costly with laparoscopy than open colorectal surgery. CONCLUSION The adoption of laparoscopy in the elderly has lagged behind open surgery and even declined in recent years despite being associated with improved clinical outcomes and reduced cost. With this tremendous value proposition to increase use of laparoscopic surgery in the elderly, further work needs to evaluate root causes of the disparity.

Abstract
Abstract
Background
Oxidative stress contributes to adverse atrial remodeling in diabetes mellitus. This can be prevented by the PPAR-γ agonist pioglitazone through its anti-oxidant and anti-inflammatory effects.
Purpose
In this study, the molecular mechanisms underlying these effects were investigated.
Methods
Rabbits were randomly divided into control (C), diabetic (DM), and pioglitazone-treated DM (Pio) groups. Echocardiographic, hemodynamic, electrophysiological, intracellular Ca2+ properties were measured. Serum PPAR-γ levels, serum and tissue oxidative stress and inflammatory markers, mitochondrial morphology, reactive oxygen species (ROS) production rate, respiratory function, and mitochondrial membrane potential (MMP) levels were measured. Protein expression of pro-fibrotic marker transforming growth factor β1 (TGF-β1), and the mitochondrial proteins (PGC-1α, fission and fusion-related proteins) were measured.
Results
Compared with controls, the DM group demonstrated larger left atrial diameter and fibrosis area associated with a higher incidence of inducible AF. Lower serum PPAR-γ level was associated with lower PGC-1α, higher NF-κB and higher TGF-β1 expression. Mn-SOD protein was not different but lower mitochondrial fission- and fusion-related proteins were detected. Mitochondrial swelling, higher mitochondrial ROS, lower respiratory control rate, lower MMP and higher intracellular Ca2+ transients were observed. In the Pio group, reversal of structural remodeling and lower inducible AF incidence were associated with higher PPAR-γ and PGC-1α. NF-κB and TGF-β1 were lower and biogenesis, fission and fusion-related protein were higher. Mitochondrial structure and function, and intracellular Ca2+ transients were improved. In HL-1 cell line, transfected with PGC-1α siRNA blunted the effect of pioglitazone on Mn-SOD protein expression and MMP collapse in H2O2-treated cells.
Conclusion
Diabetes mellitus induces adverse atrial structural and electrophysiological remodeling, abnormal Ca2+ handling and mitochondrial damage and dysfunction. Pioglitazone prevented these abnormalities through the PPAR-γ/PGC-1α pathway.
