Abstract
There is as yet no consensus as to the best choice among the three treatment options (maintenance, complete chemotherapy-free intervals [CFIs], and continuous) for metastatic colorectal cancer (CRC). We performed a meta-analysis of six trials (N = 2, 454 patients) to compare the safety and efficacy of those three treatment strategies. Maintenance appeared to offer an advantage over CFI with respect to progression-free survival (PFS) (hazard ratio [HR]: 0.53, 95% confidence interval [CI], 0.40–0.69). PFS and overall survival (OS) were comparable between the maintenance and continuous strategies (HR: 1.18, 95% CI, 0.96–1.46; HR: 1.05, 95% CI, 0.98–1.27, respectively), as was OS between the maintenance and CFI strategies (HR: 0.84; 95% CI, 0.70–1.00). The incidence of grade 3/4 toxicity, including neutropenia, neuropathy, hand-foot syndrome and fatigue, was lower with maintenance than with continuous therapy. A maintenance regimen utilizing bevacizumab-based doublets appeared to confer a slight advantage over bevacizumab monotherapy with respect to PFS (P = 0.011). Maintenance appeared to reduce cumulative grade 3/4 toxicity as compared to the continuous strategy, while showing comparable efficacy. Bevacizumab-based doublets appeared to be of particular value in patients with metastatic CRC.

Abstract
OBJECTIVE To compare brain-derived neurotrophic factor (BDNF) levels between offspring of individuals with bipolar disorders (BD) and healthy controls (HCs) and investigate the effects of BDNF levels and body mass index (BMI) on brain structures. METHOD Sixty-seven bipolar offspring and 45 HCs were included (ages 8-28). Structural images were acquired using 3.0 Tesla magnetic resonance imaging. Serum BDNF levels were measured using enzyme-linked immunosorbent assay. Multivariate and univariate analyses of covariance were conducted. RESULTS Significantly higher BDNF levels were observed among bipolar offspring, relative to HCs (P > 0.025). Offspring status moderated the association between BDNF and BMI (F1 =4.636, P = 0.034). After adjustment for relevant covariates, there was a trend for a significant interaction of group and BDNF on neuroimaging parameters (Wilks'λ F56,94 =1.463, P = 0.052), with significant effects on cerebellar white matter and superior and middle frontal regions. Brain volume and BDNF were positively correlated among HCs and negatively correlated among bipolar offspring. Interactions between BDNF and BMI on brain volumes were non-significant among HCs (Wilks'λ F28,2 =2.229, P = 0.357), but significant among bipolar offspring (Wilks'λ F28,12 =2.899, P = 0.028). CONCLUSION Offspring status and BMI moderate the association between BDNF levels and brain structures among bipolar offspring, underscoring BDNF regulation and overweight/obesity as key moderators of BD pathogenesis.

Abstract
RATIONALE Cronkhite-Canada Syndrome (CCS) is an idiopathic, nonhereditary syndrome haracterized by gastrointestinal (GI) polyposis and ectodermal changes including alopecia, onychatrophia, and pigmentation. CCS colon polyps were previously considered to be benign neoplasms. However, serrated adenoma was reported to be associated with malignant neoplasms in some cases of gastric and colorectal carcinomas, and esophageal cancers. Although malignant colon and gastric cancer have been reported in CCS, reports of distant metastasis have been rare in CCS. PATIENT CONCERNS A 58-year-old male was referred from a nearby hospital with diarrhea and weight loss. The patient was hypoproteinemia (17.9 g/L), and multiple polyps were observed in the large intestine. He also had alopecia, onychatrophia, and dysgeusia. DIAGNOSES The presence of multiple polyps and associated symptoms of alopecia, onychatrophia, pigmentation, and dysgeusia informed the diagnosis of CCS. INTERVENTIONS He was treated with 20mg dexamethasone acetate per day for about 3 months, 10 mg for about 9 month, 5 mg for about 1 year, and then maintained on 5 mg daily. Three years after starting treatment, colonoscopy revealed colon cancer and colon adenomas. A sigmoidectomy revealed 4 well-differentiated adenocarcinomas of the ulcerating type in the sigmoid colon, and tubularadenomas throughout the rest of the large intestine. He was treated with FOLFOX6 for 6 months. At this stage liver metastasis was found. A right hepatectomy was performed confirming hepatic metastasis of colonic adenocarcinoma, which was GPC-3(-), CD34(-), CK20(+), CDX-2(+), Hep(-), CK19(+), and CK8(+).The patient received 3 courses of hepatic arterial infusion chemotherapy. OUTCOMES The patient's status has been stable for more than 2 years, and there was no tumor recurrence or metastasis occurred. LESSONS CCS is a rare cause of multiple polyposis most often treated with hormone therapy. Regular follow-ups are very important to ensure discovery of malignant tumors at an early stage. Studies with longer-term observations and larger sample sizes will be required to confirm these observations. However, characterization of molecular markers for the early detection of malignant transformation that might allow less invasive and more cost-effective surveillance of colon cancer is urgently sought.

Abstract
Meta-analysis was conducted to systematically assess the effectiveness and safety of programmed cell death protein-1 or ligand-1 (PD-1 or PD-L1) antibodies versus docetaxel alone in advanced non small cell lung cancer (NSCLC). In addition, the prognostic significance of PD-L1 expression in advanced NSCLC was also investigated. 5 eligible studies including 3579 patients were identified through comprehensive search of multiple databases. The results showed that pooled hazard ratios (HR) for overall survival (OS) and progression free survival (PFS) were 0.69 (95% CI: 0.63-0.75; p < 0.001) and 0.87 (95% CI: 0.80-0.94; p < 0.001), between PD-1/PD-L1 antibodies and docetaxel treatment arms, respectively. The pooled relative risk (RR) value for objective response rate (ORR) was 1.53, (95% CI: 1.16-2.01, p = 0.003). Further, subgroup analysis based on PD-L1 expression indicated that pooled HR for OS was significant with 0.66(95% CI: 0.59-0.74, p < 0.001) for PD-L1≥1%. However, PD-L1 < 1% had HR value of 0.79 (95% CI: 0.67-0.93, p = 0.006). Our study concluded that advanced NSCLC patients benefited more with PD-1/PD-L1 antibodies than docetaxel in the second line treatment. PD-L1≥10% in tumor tissues is sufficient to show significant improvement in patient's outcome with PD-1/PD-L1 antibodies compared to docetaxel. Moreover, PD-1/PD-L1 antibodies treatment showed significant decrease in conventional chemotherapy adverse events, but increased immune-associated adverse effects.

Abstract
Background This retrospective study investigated the association between the Charlson comorbidity index (CCI) score and the survival of patients with stage IIIB-IV (advanced, non-resectable) non-small cell lung cancer (NSCLC) who also did not have gene mutations in epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK). Methods The records of 165 patients (28–80 y, median 61 y) who met the above criteria and were admitted to Beijing Friendship Hospital Capital Medical University from 1 May 2010 to 1 October 2014were reviewed. Associations between baseline variables and the CCI score were assessed via univariate and multivariate logistic regression analysis. Overall survival was defined as the time from the first clinic visit to death from any cause, or to the end of follow-up. Survival curves were estimated via the Kaplan-Meier method and compared with the log-rank test. Results Logistic regression analyses indicated that smoking and performance status were independently associated with the CCI score. Smoking was associated with an increased risk of mortality (odds ratio (OR) 4.12 (95% confidence interval [CI] 1.92–8.84) compared to non-smokers), as was performance status 2 (ambulatory, capable of self-care, unable to perform any work activities; active for >50% of waking hours) (OR 2.22 (95% CI, 1.14–4.33) compared to performance status 1). Univariate Cox’s regression analyses showed that the hazard ratios were significantly associated with the CCI score (P = 0.009), smoking (P = 0.042), and male gender (P = 0.021). Conclusion The CCI score is an important prognostic factor for the prediction of overall survival in patients with stage IIIB-IV NSCLC who are negative for EGFR and ALK gene mutations.

Abstract
The neuro-anatomical substrates of major depressive disorder (MDD) are still not well understood, despite many neuroimaging studies over the past few decades. Here we present the largest ever worldwide study by the ENIGMA (Enhancing Neuro Imaging Genetics through Meta-Analysis) Major Depressive Disorder Working Group on cortical structural alterations in MDD. Structural T1-weighted brain magnetic resonance imaging (MRI) scans from 2148 MDD patients and 7957 healthy controls were analysed with harmonized protocols at 20 sites around the world. To detect consistent effects of MDD and its modulators on cortical thickness and surface area estimates derived from MRI, statistical effects from sites were meta-analysed separately for adults and adolescents. Adults with MDD had thinner cortical gray matter than controls in the orbitofrontal cortex (OFC), anterior and posterior cingulate, insula and temporal lobes (Cohen's d effect sizes: -0.10 to -0.14). These effects were most pronounced in first episode and adult-onset patients (>21 years). Compared to matched controls, adolescents with MDD had lower total surface area (but no differences in cortical thickness) and regional reductions in frontal regions (medial OFC and superior frontal gyrus) and primary and higher-order visual, somatosensory and motor areas (d: -0.26 to -0.57). The strongest effects were found in recurrent adolescent patients. This highly powered global effort to identify consistent brain abnormalities showed widespread cortical alterations in MDD patients as compared to controls and suggests that MDD may impact brain structure in a highly dynamic way, with different patterns of alterations at different stages of life.

Abstract
Colorectal cancer (CRC) is the fourth leading cause of cancer-induced mortality. Histone deacetylase 2 (HDAC2) is involved in prognosis and therapy of CRC. This study aimed to explore novel therapeutic targets for CRC. The alteration of HDAC2 expression in CRC tissues was estimated by qRT-PCR. After lentivirus transfection, HDAC2 knockdown was confirmed by western blot analysis. The effect of HDAC2 knockdown on cell proliferation was then assessed by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Screened by TargetScan, microRNA (miR)-455 was predicted to bind to 3′UTR of HDAC2 and the prediction was verified by luciferase assay. Finally, cells were transfected, respectively, with miR-455 mimics or miR-455 negative control (miR-NC) and the expression of HDAC2, cell proliferation and apoptosis of transfected cells were respectively evaluated by western blot analysis, MTT assay and flow cytometry. Results showed that the HDAC2 expression was up-regulated in CRC tissues (P<0.05). HDAC2 knockdown significantly decreased cell viability at day 3 (P<0.05), day 4 (P<0.01), and day 5 (P<0.001) after infection. Then, miR-455 was verified to directly target HDAC2, resulting in a significant difference in luciferase activity (P<0.01). Moreover, miR-455 decreased the expression of HDAC2 (P<0.01). miR-455 remarkably decreased cell viability at day 3 (P<0.05), day 4 (P<0.01), and day 5 (P<0.001) after transfection while inducing cell apoptosis (P<0.001). In conclusion, miR-455 inhibited cell proliferation while inducing cell apoptosis by targeting HDAC2 in CRC cells.

Abstract
Human epidermal growth factor receptor 3 (HER3) is closely involved in tumor progression and is an important target of therapy. To evaluate the prognostic significance of HER3 in malignant solid tumors, we searched the PUBMED, EMBASE and CNKI databases for relevant studies written in English or Chinese up to December 2015. Fifteen studies comprising 2964 patients were identified. The HER3+ rate ranged from 9.0-75.1 % in malignant solid tumors: 30.3-75.1 % in breast cancers, 51.1-74.5 % in colorectal cancers, 13.7-59.0 % in gastric cancers, and 54.5-74.4 % in cervical cancers. For patients with a malignant solid tumor, the death risk was higher for those with a HER3+ tumor than for those with a HER3− tumor (HR 1.60, 95% CI: 1.27 - 2.02, P < 0.001). Subgroup analysis revealed this was also the case for patients with digestive or gastric cancer (HR 1.78, P < 0.001; HR 2.18, P < 0.001). By contrast, HER3 had no prognostic significance in colorectal or breast cancer (HR 1.52, P = 0.296; HR 1.23, P = 0.108). HER3+ is thus associated with poor survival in overall and in gastric cancer. The prognostic significance of HER3+ in other tumors is uncertain and deserves further study.

Abstract
Objective: To isolate exosomes from the serum of colon cancer patients and identify RNAs in the small vesicles. Methods: ExoQuick-TC™ Exosome Precipitation Solution was used for exosome isolation and the shapes of exosomes were observed under a transmission electron microscope. Mass spectrometry was used to identify the classification of miRNAs encapsulated in exosomes, and the expression levels of miRNA-21,-133a, and -181b in exosomes were detected by RT-PCR. Results: Exosomes isolated from serum of colon cancer patients were circular-or oval-shaped and vary in size with a diameter of 40-100 nm. Mass spectrometry shows that the main RNAs in exosomes are small RNAs; the levels of these small RNAs in exosomes are significantly higher compared with fresh serum. There is still a tiny amount of small RNAs in exosome-free serum, but the amounts are significantly lower than that in exosomes. No more RNAs were detected in the repeated freezing and thawing serum, but there were still some RNAs detectable in the exosomes extracted from these serums. MiRNA-21, -133a and -181b can be detected in exosomes, and the level of miRNA-21 is associated with early diagnosis of colon cancer. Conclusion: This study proves that commercial kits for exosome separation are more convenient and time-saving and that mass spectrometry is capable of identifying the miRNAs in exosomes. Compared with direct extraction of miRNAs from the serum, the method of isolating exosomes from the serum firstly and then extracting miRNAs from the exosomes can enhance the stability and integrity of their inner miRNAs. Also, we demonstrate that the exosomal miRNA-21 expression is associated with the early diagnosis of colon cancer.

Abstract
In this study, we explore the correlations between indoor climate change and human thermal adaptation, especially with regard to the timescale and weighting factors of physiological adaptation. A comparative experiment was conducted in China where wintertime indoor climate in the southern region (devoid of space heating) is much colder than in the northern region (with pervasive district heating). Four subject groups with different indoor thermal experiences participated in this climate chamber experiment. The results indicate that previous indoor thermal exposure is an important contributor to occupants' physiological adaptation. More specifically, subjects acclimated to neutral-warm indoors tended to have stronger physiological responses and felt more uncomfortable in moderate cold exposures than those adapted to the cold. As for the driving force of thermal adaptation, physiological acclimation is an important aspect among all the supposed adaptive layers. However, the physiological adaptation speed lags behind changes in the overall subjective perception.

Abstract
BACKGROUND Some studies have demonstrated that subjects with chronic burnout showed cognitive impairments; however, cognitive performance in burnout has been under-investigated. Increasing evidence show that brain-derived neurotrophic factor (BDNF) plays a critical role in cognitive function. We hypothesized that decreased BDNF may be associated with cognitive impairments in burnout, which has not been investigated yet. The aim of the present study was to examine the association of BDNF with cognitive impairment in burnout. METHOD Using a cross-sectional design, 712 healthy subjects were recruited from a general hospital and they were all measured with the Maslach Burnout Inventory (MBI). We assessed part of subjects on the repeatable battery for the assessment of neuropsychological status (RBANS) (n=192) and serum BDNF levels (n=127). RESULTS 30.5% of the subjects had burnout. Compared to those non-burnout subjects, the burnout subjects were younger, had significant lower BDNF levels (p=0.003) and scored lower on immediate memory, RBANS total score and attention (all p<0.05). Interestingly, after the Bonferroni correction, there were negative correlations between BDNF and MBI total score or reduced professional accomplishment (PA). Moreover, BDNF was positively associated with immediate memory, attention and RBANS total score. Further multiple regression analysis showed that BDNF was an independent contributor to the RBANS total score and attention, and BDNF and MBI depersonalization (DP) were independent contributors to immediate memory. In addition, there was mediating effect of BDNF in the relation between burnout and cognitive impairments. CONCLUSIONS Our results suggest that burnout is associated with significant cognitive impairments and decreased BDNF. Moreover, decreased BDNF is associated with cognitive impairments in burnout.

Abstract
Objective: To investigate the changes in protein expression in patients with 1-bromopropane (1-BP) poisoning using high-throughput proteomic technique and to screen out protein markers. Methods: Serum samples were collected from 3 patients with 1-BP poisoning and 15 controls. The label-free proteomic tech-nique was used for the quantitation and identification of proteins expressed in these samples, and the results were compared between the patients with 1-BP poisoning and the control population. The bioinformatics tools were used to analyze the function of differentially expressed proteins. Results: Compared with the control popula-tion, the patients with 1-BP poisoning had >2-fold upregulation of 38 proteins and >2-fold downregulation of 68 proteins. The differentially expressed proteins were mainly involved in immune response, signal transduction, and stress response. Conclusion: The proteins screened out may be potential protein markers for 1-BP poison-ing, which provides reliable and precise methods and thoughts for the diagnosis of 1-BP poisoning.

Abstract
Background Prognostic factors aid in the stratification and treatment of cancer. This study evaluated the prognostic significance of human epidermal growth factor receptor (HER) family members (HER1–4) expression in patients with operable pancreatic cancer. Methods The expression of individual HER proteins in patient tissue specimens was detected by immunohistochemistry staining. Patient follow-up time was between 1.0 and 78.1 months. Results Positive expression of HER1, HER2, HER3 and HER4 was detected in 41.4, 60.0, 24.3 and 65.7% of cases, respectively. Kaplan–Meier analysis revealed that HER3 positive expression was associated with decreased median survival time (12.0 vs. 25.6 months for HER3 positive and negative groups, respectively; P = 0.013). Cox’s regression confirmed that positive HER3 expression was an independent predictor of poor survival (RR = 3.684, P = 0.001). In contrast, HER4 negative patients had a significantly decreased median survival time when compared with HER4 positive patients (11.4 vs. 25.6 months, respectively; P = 0.027). However, HER4 was not an independent predictor of survival. No significant association between HER1 or HER2 expression and survival was observed (P = 0.626 & P = 0.859, respectively). Conclusions HER3 is an independent prognostic marker for patients with operable pancreatic cancer. HER4 may also be of potential prognostic value in this disease and deserves further attention.

Abstract
OBJECTIVE To explore the safety and efficacy of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in preventing chemotherapy-induced neutropenia in patients with breast cancer and non-small cell lung cancer (NSCLC), and to provide the basis for clinical application. METHODS According to the principle of open-label, randomized, parallel-group controlled clinical trial, all patients were randomized by 1∶1∶1 into three groups to receive PEG-rhG-CSF 100 μg/kg, PEG-rhG-CSF 6 mg, or rhG-CSF 5 μg/kg, respectively. The patients with breast cancer received two chemotherapy cycles, and the NSCLC patients received 1-2 cycles of chemotherapy according to their condition. All patients were treated with the combination chemotherapy of TAC (docetaxel+ epirubicin+ cyclophosphamide) or TA (docetaxel+ epirubicin), or the chemotherapy of docetaxel combined with carboplatin, with a 21 day cycle. RESULTS The duration of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg and PEG-rhG-CSF 6 mg groups were similar with that in the rhG-CSF 5 μg/kg group (P>0.05 for all). The incidence rate of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group, and G-CSF 5 μg/kg group were 69.7%, 68.4%, and 69.5%, respectively, with a non-significant difference among the three groups (P=0.963). The incidence rate of febrile neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg/kg group were 6.1%, 6.4%, and 5.5%, respectively, showing no significant difference among them (P=0.935). The incidence rate of adverse events in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg / kg group were 6.7%, 4.1%, and 5.5%, respectively, showing a non-significant difference among them (P=0.581). CONCLUSIONS In patients with breast cancer and non-small cell lung cancer (NSCLC) undergoing TAC/TA chemotherapy, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF at 48 hours after chemotherapy show definite therapeutic effect with a low incidence of adverse events and mild adverse reactions. Compared with the continuous daily injection of rhG-CSF 5 μg/kg/d, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF has similar effect and is more advantageous in preventing chemotherapy-induced neutropenia.

Abstract
Maternal post-traumatic stress disorder (PTSD) increases the risk of adverse neurodevelopmental outcomes in the child. Epigenetic alternations may play an essential role in the negative effects of PTSD. This study was aimed to investigate the possible epigenetic alterations of maternal PTSD, which underpins the developmental and behavioral impact. 24 pregnant Sprague-Dawley (SD) rats were randomly grouped into PTSD and control groups. Open-field tests (OFTs), elevated pull maze (EPM) assays, gene expression profile chip tests, and methylated DNA immunoprecipitation sequencing (MeDIP-Seq) were performed on the offsprings 30 days after birth. The results showed that PTSD offsprings had lower body weights and OFT scores than control offsprings. Enzyme-linked immunosorbent assays showed that serotonin receptor (5-HT) and dopamine levels were significantly lower in PTSD offsprings than in control offsprings. In contrast, corticosterone levels were higher in the PTSD group than in the control group. In a comparison of the PTSD group versus the control group, 4,160 significantly differentially methylated loci containing 30,657 CpGs were identified; 2,487 genes, including 13 dysmethylated genes, were validated by gene expression profiling, showing a negative correlation between methylation and gene expression (R = -0.617, P = 0.043). In conclusion, maternal PTSD could delay the physical and behavioral development of offsprings, and the underlying mechanism could contribute to changes in neurotransmitters and gene expression, owing to dysregulation of whole-genome methylation. These findings could support further clinical research on appropriate interventions for maternal PTSD to prevent methylation dysregulation and developmental retardation.

Abstract
BACKGROUND Esophageal cancer is a common and aggressive malignant tumor. This study aimed to investigate the association between human papillomavirus (HPV) Types 16 and 18 and esophageal carcinoma (EC) in the world population by conducting a meta-analysis. MATERIALS AND METHODS Computerized bibliographic and manual searches were performed to identify all eligible literatures between 1982 and 2014. PUBMED (http://www.ncbi.nlm.nih.gov/pubmed/) and CNKI (http://www.cnki.net/) were the primary sources of case-control studies, and key words used include human papillomavirus, HPV, esophageal, esophagus, cancer, carcinoma, and tumor. All searches were performed by reviewing articles and abstracts cited in the published systematic reviews and case-control studies. Prospective studies that reported relative risk (RR) estimates with 95% CIs for the association between HPV and EC were included. RESULTS Thirty-three randomized studies were identified, and the main features of these trials were included in this systematic review. HPV infection rate in the EC group was 46.5%, while HPV infection rate in the control group was 26.2% (OR = 1.62; 95% CI, 1.33-1.98). In China, the merger OR value was 1.62 (95% CI: 1.26-2.07); while in the Asian region, the merger OR value was 1.63 (95% CI: 1.29-2.04). There were statistical differences in HPV testing due to different detection methods such as PCR, IHC and ISH. In the PCR detection group, the merger OR value was 1.61 (95% CI: 1.33-1.95). CONCLUSIONS These results indicate that HPV infection and the incidence of EC are closely associated.

Abstract
This study was aimed to determine the risk factors of Carbapenem-resistant Enterobacteriaceae (CRE) nosocomial infections and assess the clinical outcomes. A case-case-control design was used to compare two groups of case patients with control patients from March 2010 to November 2014 in China. Risk factors for the acquisition of CRE infections and clinical outcomes were analyzed by univariable and multivariable analysis. A total of 94 patients with CRE infections, 93 patients with Carbapenem-susceptible Enterobacteriaceae (CSE) infections, and 93 patients with organisms other than Enterobacteriaceae infections were enrolled in this study. Fifty-five isolates were detected as the carbapenemase gene. KPC-2 was the most common carbapenemase (65.5 %, 36/55), followed by NDM-1 (16.4 %, 9/55), IMP-4 (14.5 %, 8/55), NDM-5 (1.8 %, 1/55), and NDM-7 (1.8 %, 1/55). Multivariable analysis implicated previous use of third or fourth generation cephalosporins (odds ratio [OR], 4.557; 95 % confidence interval [CI], 1.971-10.539; P < 0.001) and carbapenems (OR, 4.058; 95 % CI, 1.753-9.397; P = 0.001) as independent risk factors associated with CRE infection. The in-hospital mortality of the CRE group was 57.4 %. In the population of CRE infection, presence of central venous catheters (OR, 4.464; 95 % CI, 1.332-14.925; P = 0.015) and receipt of immunosuppressors (OR, 7.246; 95 % CI, 1.217-43.478; P = 0.030) were independent risk factors for mortality. Appropriate definitive treatment (OR, 0.339; 95 % CI, 0.120-0.954; P = 0.040) was a protective factor for in-hospital death of CRE infection. Kaplan-Meier curves of the CRE group had the shortest survival time compared with the other two groups. Survival time of patients infected with Enterobacteriaceae with a high meropenem MIC (≥8 mg/L) was shorter than that of patients with a low meropenem MIC (2,4, and ≤ 1 mg/L). In conclusion, CRE nosocomial infections are associated with prior exposure to third or fourth generation cephalosporins and carbapenems. Patients infected with CRE had poor outcome and high mortality, especially high meropenem MIC (≥8 mg/L). Appropriate definitive treatment to CRE infections in the patient is essential.

Abstract
OBJECTIVES To explore the differences in the features and impact on quality of life (QOL) of non-motor symptoms (NMS) of tremor dominant (TD) and postural instability gait disorder (PIGD) phenotypes early Parkinson's disease (PD), as well as the determinants of poor QOL for TD and PIGD phenotypes. METHODS This cross-sectional study recruited 301 patients with early PD and 101 healthy controls. Specific assessments used for NMS included NMS scale (NMSS), the Hamilton Rating Scale for Depression (HRSD-24), the Hamilton Anxiety Scale (HAMA), the Mini-Mental state examination (MMSE), and Addenbrooke's Cognitive Exam-Revised (ACE-R). QOL was evaluated with the PD Quality of Life Questionnaire (PDQ-39). RESULTS Tremor dominant phenotype patients were 117 (38.9%), and PIGD were 155 (51.5%). Compared with TD patients, patients with PIGD had higher frequency of NMS (9.0 ± 5.3 vs 6.7 ± 4.6, P < 0.001), NMSS total scores (39.6 ± 34.5 vs 24.4 ± 22.7, P < 0.001) and more poorly for PDQ-39 summary index (19.2 ± 14.0 vs 13.8 ± 11.5, P = 0.001). There was no difference in the impact of NMS measured with NMSS on QOL between PIGD and TD phenotypes. PIGD phenotype had little impact on poor QOL once the effect of depression was taken into account. Depression was a primary negative predictor for QOL in both TD and PIGD patients (Beta: 0.697 and 0.619, respectively, P < 0.001). CONCLUSIONS PIGD phenotype had a higher prevalence of NMS and worse QOL than TD phenotype. Depression is related to a dramatic decline in QOL in both TD and PIGD phenotype patients with PD.

Abstract
Research has shown that a stable thermal environment with tight temperature control cannot bring occupants more thermal comfort. Instead, such an environment will incur higher energy costs and produce greater CO2 emissions. Furthermore, this may lead to the degeneration of occupants' inherent ability to combat thermal stress, thereby weakening thermal adaptability. Measured data from many field investigations have shown that the human body has a higher acceptance to the thermal environment in free-running buildings than to that in air-conditioned buildings with similar average parameters. In naturally ventilated environments, occupants have reported superior thermal comfort votes and much greater thermal comfort temperature ranges compared to air-conditioned environments. This phenomenon is an integral part of the adaptive thermal comfort model. In addition, climate chamber experiments have proven that people prefer natural wind to mechanical wind in warm conditions; in other words, dynamic airflow can provide a superior cooling effect. However, these findings also indicate that significant questions related to thermal comfort remain unanswered. For example, what is the cause of these phenomena? How we can build a comfortable and healthy indoor environment for human beings? This article summarizes a series of research achievements in recent decades, tries to address some of these unanswered questions, and attempts to summarize certain problems for future research.

Abstract
Both chemotherapy and epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) are widely applied for the treatment of non-small cell lung cancer (NSCLC), but the efficacy of these two treatments in combination is not yet clear. Thus, we sought to evaluate the efficacy of the intercalated combination of these two treatments in NSCLC. The PubMed database, EMBASE, Cochrane Controlled Trials Register, and Chinese Biomedical Database were systematically searched by two researchers for randomized clinical trials (RCTs) that examined the intercalated combination of chemotherapy and EGFR TKIs in NSCLC. Ten studies involving 1,660 patients were included in this systematic review. The statistical results showed that the intercalated combination of chemotherapy and EGFR TKIs significantly improved overall survival (OS) (hazard ratio (HR) = 0.83, 95% confidence interval (CI): 0.70–0.98), progression-free survival (PFS) (HR = 0.65, 95% CI: 0.51–0.84), and the objective response rate (ORR) (risk ratio (RR) = 1.90, 95% CI: 1.22–2.98) compared to chemotherapy alone. Similarly, compared to EGFR TKIs monotherapy, the intercalated combination of chemotherapy and EGFR TKIs seemed superior to EGFR TKIs alone in terms of PFS, ORR and DCR (PFS: HR = 0.75, 95% CI: 0.62–0.91, ORR: RR = 1.49, 95% CI: 1.12–2.00 and DCR: RR = 1.33, 95% CI: 1.15–1.54) in advanced NSCLC therapy.

Abstract
Background The combination of chemotherapy and epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) currently has become the hotspot issue in the treatment of non-small lung cancer (NSCLC). This systematic review was conducted to compare the efficacy and safety of the synchronous combination of these two treatments with EGFR TKIs or chemotherapy alone in advanced NSCLC. Methods EMBASE, PubMed, the Central Registry of Controlled Trials in the Cochrane Library (CENTRAL), Chinese biomedical literature database (CNKI) and meeting summaries were searched. The Phase II/III randomized controlled trials were selected by which patients with advanced NSCLC were randomized to receive a combination of EGFR TKIs and chemotherapy by synchronous mode vs. EGFR TKIs or chemotherapy alone. Results A total of six randomized controlled trials (RCTs) including 4675 patients were enrolled in the systematic review. The meta-analysis demonstrated that the synchronous combination group of chemotherapy and EGFR TKIs did not reach satisfactory results; there was no significant difference in overall survival (OS), time to progression (TTP) and objective response rate (ORR), compared with monotherapy (OS: HR = 1.05, 95%CI = 0.98–1.12; TTP: HR = 0.94, 95%CI = 0.89–1.00; ORR: RR = 1.07, 95%CI = 0.98–1.17), and no significant difference in OS and progression-free survival (PFS), compared with EGFR TKIs alone (OS: HR = 1.10, 95% CI = 0.83–1.46; PFS: HR = 0.86, 95% CI = 0.67–1.10). The patients who received synchronous combined therapy presented with increased incidences of grade 3/4 anemia (RR = 1.40, 95% CI = 1.10–1.79) and rash (RR = 7.43, 95% CI = 4.56–12.09), compared with chemotherapy, grade 3/4 anemia (RR = 6.71, 95% CI = 1.25–35.93) and fatigue (RR = 9.60, 95% CI = 2.28–40.86) compared with EGFR TKI monotherapy. Conclusions The synchronous combination of chemotherapy and TKIs is not superior to chemotherapy or EGFR TKIs alone for the first-line treatment of NSCLC.

Abstract
The efficacy and toxicity of oxaliplatin-based versus carboplatin/cisplatin-based doublets in patients with previously untreated nonsmall cell lung cancer (NSCLC) have been compared.We searched published randomized controlled trials of oxaliplatin-based or carboplatin/cisplatin-based medications for NSCLC. A fixed effect model was used to analyze outcomes which were expressed as the hazard ratio for overall survival (OS) and time-to-progression (TTP), relative risk, overall response rate (ORR), disease control rate (DCR), 1-year survival, and the odds ratios for toxicity were pooled.Eight studies involving 1047 patients were included. ORR tended to favor carboplatin/cisplatin but the effect was not significantly different compared with oxaliplatin doublets (P = 0.05). The effects of OS, TTP, DCR, and 1-year survival between the 2 regimens were comparable. Oxaliplatin doublets caused less grade 3/4 leukocytopenia and neutropenia. Grades 3 to 4 nonhematological toxicities and grades 3 to 4 hematological toxicities showed little difference between oxaliplatin doublets and carboplatin/cisplatin doublets.Meta-analysis shows that the efficacy of oxaliplatin doublets is similar to that of other currently used platinum doublets. The lack of significant differences in the statistic analysis does not preclude genuine differences in clinical efficacy, because higher diversities between the studies covered differences between the 2 groups in each study. Oxaliplatin combined with a third-generation agent should be considered for use as alternative chemotherapy in patients who cannot tolerate conventional platinum-based regimens because the toxicity profile is much more favorable.

Abstract
OBJECTIVE This study investigated the differences in corpus callosum (CC) volumes between women with early-stage and late-stage bipolar I (BP I) disorder using the criteria previously described in the literature. METHOD We compared women with early- and late-stage BP I using criteria described in the Staging Systems Task Force Report of the International Society for Bipolar Disorders. We included 20 patients with early stage and 21 patients with late-stage BP I and a group of 25 healthy controls. Patients and controls underwent structural magnetic resonance imaging. Information on the clinical features of bipolar disorder was collected using a standardized questionnaire. Anatomical volumes of five regions of CC were compared between the three groups. RESULTS Women with late-stage BP I disorder had reduced posterior CC volumes compared with early-stage bipolar I patients and controls (F = 6.05; P = 0.004). The difference was significant after controlling for age, comorbidity with post-traumatic stress disorder, psychotic symptoms during mood episodes, and current use of medication. CONCLUSION The posterior CC was significantly decreased in volume in women with late-stage bipolar disorder. These findings suggest that CC may be an anatomical target of neuroprogression in the course of bipolar disorder in women.

Abstract
Bloodstream infections and cytokine dysregulation are associated with high rates of morbidity and mortality among patients with influenza virus H7N9 infection. Here, massively parallel RNA sequencing was used to serially analyse plasma viruses and cytokine transcriptomes of a fatal H7N9-related case at successive times throughout the clinical course of infection. The results showed that acute viraemia with H7N9 virus occurred, and the virus was sensitive to antiviral therapy with oseltamivir. In addition, a lot of genome sequences from Acinetobacter baumannii were detected in blood on day 18 after illness onset when the bacteria were cultured. In parallel, longitudinal mRNA expression patterns of host cytokines associated with infection were analysed. This study illustrated the potential of RNA-sequencing to explore the plasma virome and expression profile of the infected host cytokines simultaneously in infectious disease.

Abstract
OBJECTIVES Depression is one of the most common mental disorders and a major public health problem in the Chinese population, especially among women. The current study aims to understand prevalence of depression symptoms and provide detailed epidemiological factors associated with depression among reproductive women in rural areas which was paid less attention in previous surveys. STUDY DESIGN Cross-sectional study. METHODS Face-to-face household interviews were conducted on 1058 women (age: 15-49 years) in rural areas from July 2012 to August 2012. Questionnaires were used to investigate the influencing factors of depression among women. Pearson's χ(2), logistic regression analysis and structural equation modelling (SEM) were applied to analyze the related factors. RESULTS The prevalence of depression among women was 30.7% [95% confidence interval (CI): 27.9%-33.5%]. Compared with non-depressed individuals, those with depression were more likely to be short of social support [odd ratio (OR): 0.940, P < 0.001) and have no one to talk with (OR: 0.366, P < 0.001), to be dissatisfied with the house (OR: 2.673, P < 0.001) and economy (OR: 2.268, P < 0.01) of their family, and to have great pressure (OR: 2.099, P < 0.01), negative life events (OR: 1.485, P < 0.05) and physical diseases (OR: 1.364, P < 0.05). Pressure status, social support assessment, and socio-economic status were negatively related to depression (correlation coefficient: -0.57, -0.27 and 0.17). CONCLUSIONS The high prevalence of depression among reproductive women in rural areas is of particular concern. Factors associated with depression may assist health care administrations to identify and assess high-risk women and target strategies accordingly.

Abstract
The deregulation of claudin-3 has been reported to correlate with the invasion and metastasis of various cancers, but little is known about its expression level and the prognostic value in squamous cell lung carcinoma (SqCC). The purpose of this study is to determine the expression levels and the prognostic value of claudin-3 in completely resected SqCC tissues, and the potential underlying mechanism. The protein expression of claudin-3, E-cadherin, β-catenin, and vimentin in the tumor tissues from 103 patients with surgically resected SqCC was examined using immunohistochemistry, western blots, as well as semi-quantitative estimation. The claudin-3 protein level was significantly associated with E-cadherin, β-catenin, and vimentin protein expression. A decreased claudin-3 protein level was significantly correlated with TNM stage, lymph node metastasis, and disease recurrence. Similarly, downregulation of E-cadherin was significantly correlated with lymph node metastasis and disease recurrence. Decreased β-catenin expression also had a significant correlation with disease recurrence. Univariate analyses indicated that the T stage, lymph node metastasis, the TNM stage, and the expression of claudin-3, β-catenin, and vimentin were significant predictors for overall survival (OS). Moreover, multivariate analyses demonstrated that the TNM stage and protein levels of claudin-3, β-catenin, and vimentin were independent predictors for OS of SqCC patients. Claudin-3 plays an important role in the epithelial-mesenchymal transition of SqCC and might be used as a potential prognostic factor for SqCC.

Abstract
Background Hepatocellular carcinoma (HCC) is prevalent worldwide and early diagnosis of HCC is critical for effective treatment and optimal prognosis. Methods Serum was screened first by immunoproteomic analysis for HCC-related tumor associated antigens (TAAs). Selected TAAs were clinically evaluated retrospectively in patients with HCC, liver cirrhosis, chronic hepatitis and healthy controls. Levels of autoantibody to the selected TAAs were measured by protein microarrays containing protein antigens of the candidate TAAs. Analyses were done by using receiver operating characteristics (ROC) to calculate diagnostic accuracy. Findings Twenty-two candidate TAAs were assessed by protein microarray analysis in 914 participants with serum α-fetoprotein (AFP) available. Twelve candidate TAAs were statistically different in signal intensity between HCC and controls. Among them, CENPF, HSP60 and IMP-2 showed AUC (area under the curve) values of 0.826, 0.764 and 0.796 respectively for early HCC. The highest prevalence of autoantibody positivity was observed in HCC cases with BCLC tumor stage A, well-differentiated histology and Child-Pugh grade C. Specifically, 73.6% or 79.3% cases of early HCC with negative AFP were positive for autoantibody to CENPF or HSP60. Interpretation Tumor-associated autoimmune reactions may be triggered by early stage HCCs. Measurement of serum autoantibody to TAAs may be complementary to AFP measurements and improve diagnosis of early HCC. Tumor-associated autoimmune reaction may be triggered by early stage HCCs, and TAAs may be potential marker for early HCC. Measurement of autoantibody to TAAs may be complementary to AFP measurements and improve diagnosis of early HCC. Generation of autoantibody to CENPF may result from autoimmune reaction in response to overexpression of CENPF in tumor cell.

Abstract
The correlation between TBX21 gene (T-box transcription factor protein 21; T-bet), which was a pivotal transcriptional regulation gene for Th1/Th2 polarization, and the development risk of esophagus squamous cell carcinoma (ESCC) was assessed in a high-risk Chinese population. A total of 302 ESCC cases and 311 normal controls coming from the highest incidence area of China were enrolled in this study. Three polymorphisms at -1499, -1514, and -1993 located in the TBX21 promoter were identified by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Logistic regression was used to determine whether the inherited variations of the TBX21 gene would associate with the risk and the clinicopathological characteristics of ESCC. Among the ESCC patients, an association between the TBX21 -1514T/C or -1993T/C polymorphisms and the lymph node or distant metastasis was found (odds ratios (ORs) were 9.46 and 4.35, respectively, all P < 0.01). By the log-additive model analysis, the results exhibited that three haplotypes, ACC, ACT, and ATC, were significantly related to the development risk of ESCC (OR = 11.81, 3.44, 2.37, respectively, all P < 0.05). TBX21 gene -1514 and -1993 polymorphisms might be counted as the influential factors for lymph node and distant metastasis to ESCC. Especially, the ACC, ACT, and ATC haplotypes derived from the TBX21 gene would increase the susceptibility to ESCC in the high-risk Chinese population.

Abstract
Over the past decade, a number of ribosomal proteins (RPs) have been found to have a role in activating the tumor suppressor p53 by directly binding to MDM2 and impeding its activity toward p53. Herein, we report that RPL5 and RPL11 can also enhance the transcriptional activity of a p53 homolog TAp73, but through a distinct mechanism. Interestingly, even though RPL5 and RPL11 were not shown to bind to p53, they were able to directly associate with the transactivation domain of TAp73 independently of MDM2 in response to RS. This association led to perturbation of the MDM2-TAp73 interaction, consequently preventing MDM2 from its association with TAp73 target gene promoters. Furthermore, ectopic expression of RPL5 or RPL11 markedly induced TAp73 transcriptional activity by antagonizing MDM2 suppression. Conversely, ablation of either of the RPs compromised TAp73 transcriptional activity, as evident by the reduction of p21 and Puma expression, in response to 5-fluorouracil (5-FU). Consistently, overexpression of RPL5 or RPL11 enhanced, but knockdown of either of them hampered, TAp73-mediated apoptosis. Intriguingly, simultaneous knockdown of TAp73 and either of the RPs was required for rescuing the 5-FU-triggered S-phase arrest of p53-null tumor cells. These results demonstrate a novel mechanism underlying the inhibition of tumor cell proliferation and growth by these two RPs via TAp73 activation.

Abstract
Thymic atrophy has been described as a consequence of infection by several pathogens including highly pathogenic avian influenza virus and is induced through diverse mechanisms. However, whether influenza A(H1N1)pdm09 infection induces thymic atrophy and the mechanisms underlying this process have not been completely elucidated. Our results show that severe infection of influenza A(H1N1)pdm09 led to progressive thymic atrophy and CD4+CD8+ double-positive (DP) T-cells depletion due to apoptosis. The viruses were present in thymus, where they activated thymic innate CD8+CD44hi single-positive (SP) thymocytes to secrete a large amount of IFN-γ. Milder thymic atrophy was observed in innate CD8+ T-cell-deficient mice (C57BL/6J). Neutralization of IFN-γ could significantly rescue the atrophy, but peramivir treatment did not significantly alleviate thymic atrophy. In this study, we demonstrated that thymic innate CD8+CD44hi SP T-cells have critical roles in influenza A(H1N1)pdm09 infection-induced thymic atrophy through secreting IFN-γ. This exceptional mechanism might serve as a target for the prevention and treatment of thymic atrophy induced by influenza A(H1N1)pdm09.
