Abstract
OBJECTIVES Frailty has become an independent risk factor for adverse outcomes in critically ill patients. This study aimed to explore the predictive ability of two electronic medical record-based frailty assessment tools, the Hospital Frailty Risk Score (HFRS) and Frailty Index based on physiological and laboratory tests (FI-lab), for long-term adverse prognosis in older critically ill survivors. DESIGN Retrospective observational study. SETTING AND PARTICIPANTS 9,082 critically ill survivors aged ≥ 65 years. MEASUREMENTS The HFRS and the 33-item FI-lab were constructed based on the published literature. Cox and logistic regression models assessed the association between frailty and 1-year mortality and post-discharge care needs. RESULTS 2,586 patients died within 1 year of follow-up. In fully adjusted models, frailty assessed using both the HFRS (per point, hazard ratio [HR] 1.06, 95% confidential interval [CI] 1.05-1.06; intermediate frailty risk, HR 2.00, 95% CI 1.78-2.25; high frailty risk, HR 3.06, 95% CI 2.68-3.50) and FI-lab (per 0.01 points, HR 1.03, 95% CI 1.03-1.03; intermediate frailty risk, HR 1.59, 95% CI 1.44-1.76; high frailty risk, HR 2.30, 95% CI 2.06-2.57) was associated with mortality. Addition of frailty indicators improved the predictive validity of the Sequential Organ Failure Assessment score for mortality (HFRS alone ∆ C-index 0.034; FI-lab alone ∆ C-index 0.016; HFRS and FI-lab combined ∆ C-index 0.042). The HFRS but not the FI-lab was associated with higher probability of post-discharge care needs. CONCLUSION Both the HFRS and FI-lab could independently predict 1-year mortality in older critically ill survivors. Adding the HFRS to the SOFA score model improved it more than adding the FI-lab. The greatest improvement was achieved when both frailty indicators were used together. These findings suggest that electronic medical record-based frailty assessment methods can be useful tools for predicting long-term outcomes in older critically ill patients.

Abstract
Objectives
This study aims to compare the clinical effectiveness of transforaminal endoscopic spine system (TESSYS) technique combined with selective nerve root block (SNRB) in treating patients with far lateral lumbar disc herniation (FLDH) and patients with central or paracentral herniation (C/PDH). Patients and methods
Between June 2015 and June 2019, a total of 204 patients (80 males, 124 females; mean age: 62.3±5.4 years; range, 51 to 66 years) with a herniated disc were included. Of these, 22 consecutive adult patients with FLDH formed the FLDH group, while 182 patients with C/PDH formed the C/PDH group. Considering that FLDH was a rare type of LDH and occurred outside the spinal canal, the patients with LDH in the spinal canal (C/PDH) were selected as the controls in our study. All cases received ultrasound-guided SNRB to identify the diseased disc and treated by the TESSYS technique. Data including demographics, duration of operation, duration of hospital stay, surgical cost, complications, Visual Analog Scale (VAS) scores for the back and leg, and Oswestry Disability Index (ODI) scores and the modified MacNab criteria were analyzed. Results
The FLDH group presented the similar clinical outcomes and costs with the C/PDH group. No significant differences in the VAS score, ODI score, and Macnab score were observed between the groups (p>0.05 for all). Both groups showed the significantly improved postoperative VAS scores on Day 3, at 1, 3, 6, and 12 months compared to baseline. The postoperative ODI scores at 6 and 12 months were also significantly improved (p<0.05). At the final follow-up at 12 months, the FLDH group showed the MacNab criteria rating excellent and good of 81.8% and C/PDH group showed 84.62%. Conclusion
The FLDH patients presented the comparable clinical effectiveness with C/PDH patients. Based on these findings, the TESSYS technique combined with ultrasound-guided SNRB for FLDH is safe and feasible with caution, although the risk of nerve root injury may be worried.

Abstract
Objective: To explore the dynamic changes of Distress Thermometer scores and the relationship between psychological distress and quality of life in Chinese early breast cancer patients during chemotherapy. Methods: This prospective study enrolled 110 Chinese postoperative early breast cancer patients between March 2019 and December 2019. The psychological distress and quality of life (QOL) of patients were assessed by using the psychological distress management screening tool and the patient quality of life scale. Logistic regression model was used to analyze the influencing factors of psychological distress degree. The correlation between distress thermometer (DT) score changes and quality of life was analyzed by Pearson correlation analysis. Results: In total, 96 valid cases were analyzed. Before chemotherapy, 47 cases (49.0%) had DT score ≥4 points. After 2 cycles of chemotherapy, 40 cases (41.7%) had DT score ≥4 points. Thirty-four patients (35.4%) had DT score ≥4 points after chemotherapy. The DT score after chemotherapy was lower than that before chemotherapy and after 2 cycles of chemotherapy. Univariate analysis showed that income level and pathological stage were still significant related to the detection of DT score ≥4 points after chemotherapy (P<0.05). The changes of DT scores before and after chemotherapy were negatively correlated with the changes of quality of life ( r=-0.298, P=0.003). Conclusions: The detection rate of psychological distress in patients with early breast cancer during chemotherapy showed a decreasing trend. Income level and tumor stage are significant factors affecting the psychological distress of patients. There is a significant correlation between the psychological distress and the quality of life during chemotherapy. We should pay attention to the evaluation and monitoring state of psychological distress of patients during chemotherapy.

Abstract
OBJECTIVE The mechanism of acquired gene mutation plays a major role in resistance to endocrine therapy in hormone receptor (HR)-positive advanced breast cancer. Circulating tumor DNA (ctDNA) has been allowed for the assessment of the genomic profiles of patients with advanced cancer. We performed this study to search for molecular markers of endocrine therapy efficacy and to explore the clinical value of ctDNA to guide precise endocrine therapy for HR-positive/human epidermal growth factor receptor-2 (HER-2)-negative metastatic breast cancer patients. METHODS In this open-label, multicohort, prospective study, patients were assigned to four parallel cohorts and matched according to mutations identified in ctDNA: 1) activation of the phosphatidylinositol-3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) signaling pathway preferred mTOR inhibitor combined with endocrine therapy; 2) estrogen receptor 1 (ESR1) mutation preferred fulvestrant; 3) HER-2 mutations preferred pyrotinib; and 4) no actionable mutations received treatment according to the clinical situation. In all cohorts, patients were divided into compliance group and violation group. The primary outcome measure was progression-free survival (PFS), and the secondary outcome measure was overall survival (OS). RESULTS In all cohorts, the combined median PFS was 4.9 months, and median PFS for the compliance and violation groups was 6.0 and 3.0 months, respectively [P=0.022, hazard ratio (HR)=0.57]. Multivariate Cox regression model showed the risk of disease progression was lower in compliance group than in violation group (P=0.023, HR=0.55). Among the patients with HER-2 mutations, the median PFS was 11.1 months in the compliance group and 2.2 months in the violation group (P=0.011, HR=0.20). There was no significant difference in the median PFS between patients who did and did not comply with the treatment protocol in patients with activation of the PI3K/AKT/mTOR or ESR1 mutation. CONCLUSIONS The results suggest that ctDNA may help to guide the optimal endocrine therapy strategy for metastatic breast cancer patients and to achieve a better PFS. Next-generation sequencing (NGS) detection could aid in distinguishing patients with HER-2 mutation and developing new treatment strategies.

Abstract
Recent evidence revealed that Hunner-type interstitial cystitis (HIC) is a robust inflammatory disease potentially associated with enhanced immune responses and histologically characterized by epithelial denudation and lymphoplasmacytic infiltration with frequent clonal expansion of infiltrating B cells. To date, few animal models that reproduce the histological and clinical correlates of HIC have yet been established. In the present study, we aimed to develop a novel animal model for HIC via autoimmunity to the bladder urothelium using the transgenic mouse model (URO-OVA) that expresses the membrane form of the model antigen ovalbumin (OVA) as a self-antigen on the bladder urothelium. OVA-specific lymphocytes (splenocytes) were generated by immunization of C57BL/6 mice with OVA protein and injected intravenously into URO-OVA mice. The splenocytes from OVA-immunized C57BL/6 mice showed increased interferon (IFN)-γ production in response to OVA stimulation in vitro. URO-OVA mice adoptively transferred with OVA-primed splenocytes developed cystitis exhibiting histological chronic inflammatory changes such as remarkable mononuclear cell infiltration predominantly composed of T and B lymphocytes, increased vascularity, and mucosal hyperemia in the bladder at days 7-28 with a peak at day 21 tested. No systemic inflammation was found in cystitis-induced URO-OVA mice, nor was any inflammation found in wild-type C57BL/6 mice adoptively transferred with OVA-primed splenocytes. Along with bladder inflammation, URO-OVA mice demonstrated significantly increased pelvic nociceptive responses, voiding dysfunction, and upregulated mRNA expression levels for IFN-γ, tumor necrosis factor-α (TNF-α), and substance P precursor in the bladder. This model reproduces the histological and clinical features of human HIC, providing a novel model for HIC research.

Abstract
TanSat is the 1st Chinese carbon dioxide (CO2) measurement satellite, launched in 2016. In this study, the University of Leicester Full Physics (UoL-FP) algorithm is implemented for TanSat nadir mode XCO2 retrievals. We develop a spectrum correction method to reduce the retrieval errors by the online fitting of an 8th order Fourier series. The spectrum-correction model and its a priori parameters are developed by analyzing the solar calibration measurement. This correction provides a significant improvement to the O2 A band retrieval. Accordingly, we extend the previous TanSat single CO2 weak band retrieval to a combined O2 A and CO2 weak band retrieval. A Genetic Algorithm (GA) has been applied to determine the threshold values of post-screening filters. In total, 18.3% of the retrieved data is identified as high quality compared to the original measurements. The same quality control parameters have been used in a footprint independent multiple linear regression bias correction due to the strong correlation with the XCO2 retrieval error. Twenty sites of the Total Column Carbon Observing Network (TCCON) have been selected to validate our new approach for the TanSat XCO2 retrieval. We show that our new approach produces a significant improvement on the XCO2 retrieval accuracy and precision when compared to TCCON with an average bias and RMSE of -0.08 ppm and 1.47 ppm, respectively. The methods used in this study can help to improve the XCO2 retrieval from TanSat and subsequently the Level-2 data production, and hence will be applied in the TanSat operational XCO2 processing.

Abstract
Background Cervical cancer (CC) is one of the most common female malignancies over the world. Microtubule-associated protein 7 (MAP7) belongs to the family of microtubule-associated proteins (MAPs) which involve in microtubule dynamics and are critical in several important cellular and intracellular activities. This study aimed to investigate the expression and potential role of MAP7 in CC. Methods The expression level of MAP7 in CC tissues and normal tissues were analyzed using the data obtained from The cancer genomes atlas (TCGA) and genotype-tissue expression (GTEx) databases. The prognostic value of MAP7 in patients with CC was analyzed by Kaplan–Meier analysis, Univariate and Multivariate analyses. Moreover, the influences of MAP7 expression alteration on the viability and motility of Caski, HeLa and C-33A cells was measured by CCK8 assay, colony formation assay, scratch assay, and transwell migration and invasion assays. Flow cytometry was conducted to determine cell apoptosis. Western blot was performed to evaluate the impact of MAP7 on the expression of apoptotic-related proteins as well as mitogen-activated protein kinase (MAPK) signaling pathway-related proteins. In vivo tumorigenicity assay was performed to explore the influence of MAP7 on tumor growth. Results Up-regulation of MAP7 was observed in CC tissues and high MAP7 expression was positively correlated with worse prognosis. Multivariate analyses suggested that MAP7 expression can be served as an independent predictor for overall survival of patients with CC. Knockdown of MAP7 markedly suppressed Caski and HeLa cell viability, migration and invasion while notably induced cell apoptosis. Furthermore, depletion of MAP7 in Caski and HeLa cells elevated the expression levels of Active-caspase 3 and Bax, but declined the level of Bcl-2. Whilst, overexpression of MAP7 in C-33A cells presented the opposite outcomes. Additionally, knockdown of MAP7 significantly decreased the phosphorylation of mitogen-activated protein kinase kinase (MEK) and extracellular signal-regulated kinase (ERK) in Caski and HeLa cells, and overexpression of MAP7 increased their phosphorylation in C-33A cells, indicating that MAP7 may regulate the MAPK signaling pathway in CC cells. In vivo assays revealed that knockdown of MAP7 remarkably repressed the growth of CC tumors. Conclusion The results of the present study suggest that MAP7 functions as a promoter during the occurrence and progression of CC, and that MAP7 may serve as a promising therapeutic target in CC.

Abstract
Ketamine exposure can lead to selective neuroapoptosis in the developing brain. p66ShcA, the cellular adapter protein expressed selectively in immature neurons, is a known pro-apoptotic molecule that triggers neuroapoptosis when activated. Sprague-Dawley rats at postnatal day 7 were subcutaneously injected in the neck with ketamine 20 mg/kg, six times at 2-hour intervals. At 0, 1, 3, and 6 hours after final injection, western blot assay was used to detect the expression of cleaved caspase-3, p66ShcA, and phosphorylated p66ShcA. We found that the expression of activated p66ShcA and caspase-3 increased after ketamine exposure and peaked at 3 hours. The same procedure was performed on a different group of rats. At the age of 4 weeks, spatial learning and memory abilities were tested with the Morris water maze. Latency to find the hidden platform for these rats was longer than it was for control rats, although the residence time in the target quadrant was similar. These findings indicate that ketamine exposure resulted in p66ShcA being activated in the course of an apoptotic cascade during the neonatal period. This may have contributed to the deficit in spatial learning and memory that persisted into adulthood. The experimental protocol was approved by the Institutional Animal Care and Use Committee at the University of Texas at Arlington, USA (approval No. A13.008) on January 22, 2013.

Abstract
BACKGROUND The protein kynureninase (KYNU) has recently been reported to participate in the pathological processes of various diseases. AIM To explore the expression and the biological function of KYNU in cutaneous squamous cell carcinoma (cSCC). METHODS Expression of KYNU in cSCC cell lines and tissues was firstly evaluated based on the Gene Expression Omnibus and the Oncomine databases. Quantitative reverse transcription-PCR was performed to determine the mRNA expression of KYNU in cSCC cell lines. Small interfering RNA (siRNA) was used for silencing KYNU. The effect of KYNU on the growth and motility of cSCC cells was determined by cell counting kit-8, wound-healing and Transwell assays, and western blotting was used to determine the protein expression of KYNU, AKT, phosphoinositide 3-kinase (PI3K), phosphorylated (p)-AKT and p-PI3K. RESULTS KYNU was significantly upregulated in cSCC tissues and cell lines. Knockdown of KYNU using siRNA noticeably suppressed the proliferation, migration and invasion ability of SCL-1 cells (P < 0.01). Western blotting revealed that phosphorylation of AKT and PI3K was markedly inhibited after silencing KYNU. The ratios of p-AKT/AKT and p-PI3K/PI3K were significantly decreased in the si-KYNU group compared with the control group. CONCLUSION Depletion of KYNU could inhibit the growth of cSCC cells, possibly through modulating PI3K/AKT pathway. These data indicate that KYNU takes a key part in the malignant progression of cSCC, and could be considered as a promising therapeutic target for cSCC treatment.

Abstract
Endometriosis is a condition characterized by the presence of endometrial tissues outside the uterus. Endometriotic stromal cells (ESCs) are known to undergo regeneration and are linked to the causation of endometriosis. Activation of stromal cells by local inflammatory cytokines is proposed to be one of the mechanisms of endometriosis development. Takeda-G-protein-receptor-5 (TGR5) is a G protein-coupled bile acid receptor that plays multiple roles in various cells and tissues. In this study, we show that activation of TGR5 by its specific agonist, INT-777, protects ESCs from inflammation and oxidative stress induced by tumor necrosis factor-α (TNF-α). TGR5 is fairly expressed in cultured ESCs, and TNF-α treatment suppresses TGR5 expression. Activation of TGR5 by its synthetic agonist, INT-777, dramatically reduces the production of pro-inflammatory cytokines and adhesion molecules by TNF-α, including interleukin-6 (IL-6), interleukin-8 (IL-8), monocyte chemoattractant protein-1 (MCP-1), intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1). Moreover, INT-777 suppresses TNF-α-induced NADPH oxidase 4 (NOX4) expression and ameliorates cellular oxidative stress. Mechanistically, our findings demonstrate that INT-777 suppresses TNF-α-induced c-Jun N-terminal kinase (JNK) activation via suppression of p-JNK. INT-777 inhibits TNF-α-induced activation of the activator protein-1 (AP-1) pathway owing to its suppression of c-Jun and c-fos as well as transfected AP-1 promoter. INT-777 also inhibits nuclear factor-κB (NF-κB) activation as revealed by its suppression of TNF-α-induced nuclear p65 accumulation and NF-κB promoter. Collectively, our data indicate that activation of TGR5 by its agonist has protective effects against inflammation and reactive oxygen species (ROS) in cytokine-induced activation of ESCs. Therefore, INT-777 may have an implication in the clinical treatment of endometriosis.

Abstract
Objective: To access the influence of voice disorders on children's voice-related quality of life through the parental version of pediatric voice handicap index (pVHI). Methods: From April 2017 to March 2018, a total of 192 children with voice disorders (dysphonic group) and 111 children without voice disorders (control group) were enrolled in this work. Parents of children in both groups were asked for fill out the questionnaire containing the parental version of pVHI and the data of non-normal distribution were analyzed by Mann-Whitney U test. Spearman test was used for correlation analysis. Results: (1)Vocal cord nodule was the most common voice disorder in children, and boys were more susceptible to voice disorder than girls in this study (70.3%(135/192) vs 29.7%(57/192)). (2)The most common voice abuse or misuse habit was "Shouting loudly". (3)In dysphonic group, the scores of function, physiology, emotion and total were higher than those in control group (all P<0.05). (4)In dysphonic group, there was a weak correlation between the parents' overall evaluation of the children's voice status and the three dimensions of the parental version of pVHI (function: r=0.339, physiology: r=0.334, emotion: r=0.208, all P<0.001). Conclusions: Voice disorders can cause a negative impact on children's quality of life. Parental version of pVHI can be used to assess the voice-related quality of life in children with voice disorders.

Abstract
Background Ovarian cancer is a prominent public health problem which affects people all around the world. Platinum-based chemotherapy is a common treatment for ovarian cancer, however, the effectiveness of chemotherapy varies from patient to patient. The excision repair cross complementation group 1 (ERCC1) protein may mediate chemotherapy resistance. A meta-analysis was conducted to explore whether platinum-based chemotherapy effectiveness could be attributed to the ERCC1 C19007T polymorphisms. Methods Seven major databases (EMBASE, Web of Science, Pubmed, Springer Link, Chinese National Knowledge Infrastructure (CNKI), EBSCO and Science Direct databases) were searched for eligible studies. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to evaluate the results. Results In this meta-analysis, 1169 subjects (425 non-responders and 744 responders) from 8 studies were included. The overall OR (C vs. T alleles) using random model was 1.07 (95% CI 0.75-1.52, P = 0.7), which was not statistically significant. Moreover, there was no significant difference in the analysis by race. Conclusion There is no association between the ERCC1 C19007T polymorphism and platinum-based chemotherapy effectiveness in ovarian cancer. The polymorphism did not have a significant impact on platinum-based chemotherapy in non-responders and responders.

Abstract
Objective To purify the recombinant protein specific to conserved region of forkhead box O3 (FOXO3) and prepare mouse anti-human FOXO3 polyclonal antibody. Methods The DNA fragment (aa290-472) encoding conserved domain of FOXO3 was amplified by PCR, and subsequently cloned into pET28a vector. Following transformation into E.coli BL21, the soluble fusion protein His-FOXO3 was induced by IPTG and purified by Ni-NTA affinity chromatography. The purified protein was used to immunize BALB/c mice to generate polyclonal antibody. The characteristics of the polyclonal antibody were assessed by ELISA, Western blotting and immunoprecipitation assays. Results We successfully prepared the expression vector pET28a-FOXO3 (aa290-472) and expressed the purified fusion protein in a soluble form. By immunizing mice with the fusion protein, we obtained anti-human FOXO3 polyclonal antibody. ELISA and Western blotting showed that the mouse antibody could recognize specifically the endogenous FOXO3 protein. Conclusion The polyclonal antibody against conserved domain of FOXO3 can identify the endogenous FOXO3 protein. It can be used to analyze the endogenous FOXO3 expression level.

Abstract
Objective: To investigate the clinical and pathological features and prognosis of white lesion of vocal cord. Methods: One hundred and fifty-four cases of white lesion of vocal cord from January 2009 to February 2016 were retrospectively analysed. All the patients had undergone the resection of white lesion of vocal cord resection through retaining laryngoscope under general anesthesia with the specimens pathologically examined. Results: There were 148 males and 6 females in this study. The ages ranged from 36 to 83 years, and the median age was 54.5.There were 103(66.88%) long-term smokers, and 64(41.56%) long-term drinkers. Postoperative pathology showed that chronic mucosal inflammation in 19 cases (12.34%), squamous epithelial hyperplasia in 56 cases(36.36%), mild dysplasia in 25 cases(16.23%), moderate dysplasia in 34 cases(22.08%), severe dysplasia in 12 cases(7.79%), carcinoma in situ in 6 cases(3.90%), and invasive carcinoma in 2 cases(1.30%). The recurrence rate and canceration rate of chronic mucosal inflammation were 0. The recurrence rate of squamous epithelial hyperplasia was 10.71%, the canceration rate was 0.The recurrence rate of mild dysplasia was 8.00%, the canceration rate was 0. The recurrence rate of moderate dysplasia was 20.59%, the canceration rate was 8.82%. The recurrence rate of severe dysplasia was 25.00%, the canceration rate was 16.67%. Conclusions: White lesion of vocal cord is a predominantly male disease. Long-term smokering and drinking are one of common causes. The final diagnosis of white lesion of vocal cord relies on the pathology. Closed observation is necessary for theses dysplasia cases. The majority of which are benign, the operation effect is good.

Abstract
Cervical cancer is the second most common cancer and the third leading cause of cancer-related death among females in less developed countries. Studies have shown that the single-nucleotide polymorphisms of interleukin 6 might be associated with cervical cancer risk. A total of 710 articles from EMBASE, EBSCO, Web of science, PubMed, Springer link, and Chinese National Knowledge Infrastructure databases were reviewed in our study. A meta-analysis on the associations between interleukin 6 rs1800795 polymorphism and cervical cancer risk was carried out by comparison using 5 genetic models. In this systematic review, 5 studies were analyzed. The pooled population included 2735 participants (1210 cases and 1525 controls). The overall odds ratio (G vs C alleles) using fixed-effects model was 0.85 (95% confidence interval 0.75-0.97), P = .02. Our results show that the C genotype of interleukin 6 rs1800795 is associated with higher cervical cancer risk. Our results indicate that interleukin 6 rs1800795 polymorphism might be associated with susceptibility to cervical cancer.

Abstract
Ketamine, a dissociative anesthetic most commonly used in many pediatric procedures, has been reported in many animal studies to cause widespread neuroapoptosis in the neonatal brain after exposure in high doses and/or for a prolonged period. This neurodegenerative change occurs most severely in the forebrain including the anterior cingulate cortex (ACC) that is an important brain structure for mediating a variety of cognitive functions. However, it is still unknown whether such apoptotic neurodegeneration early in life would subsequently impair the synaptic plasticity of the ACC later in life. In this study, we performed whole-cell patch-clamp recordings from the ACC brain slices of young adult rats to examine any alterations in long-term synaptic plasticity caused by neonatal ketamine exposure. Ketamine was administered at postnatal day 4-7 (subcutaneous injections, 20mg/kg given six times, once every 2h). At 3-4weeks of age, long-term potentiation (LTP) was induced and recorded by monitoring excitatory postsynaptic currents from ACC slices. We found that the induction of LTP in the ACC was significantly reduced when compared to the control group. The LTP impairment was accompanied by an increase in the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor-mediated excitatory synaptic transmission and a decrease in GABA inhibitory synaptic transmission in neurons of the ACC. Thus, our present findings show that neonatal ketamine exposure causes a significant LTP impairment in the ACC. We suggest that the imbalanced synaptic transmission is likely to contribute to ketamine-induced LTP impairment in the ACC.

Abstract
OBJECTIVE To assess the diagnostic value of narrow-band imaging(NBI) in the diagnosis of central lung cancer. METHODS Patients (n = 153) suspected of having lung cancer underwent white light bronchoscopy(WLB), NBI and autofluorescence bronchoscopy(AFB) in turn. At least 3 biopsies in each case were taken from sites visualized as lesions. The sensitivity and specificity of NBI, AFB and combination of NBI and AFB were compared. RESULTS There were 106 male (69.3%) and 47 female patients (30.7%). By NBI, 91 and 62 cases were positive and negative respectively. The sensitivity and specificity of NBI were 63.5% (87/137) and 75.0% (12/16) respectively. By AFB, 140 and 13 cases were positive and negative respectively. The sensitivity and specificity of AFB were 94.2% (129/137) and 87.5% (5/16) respectively. By NBI combined with AFB, 133 and 20 cases were positive and negative respectively, the sensitivity and specificity being 95.6% (131/137) and 87.5% (14/16) respectively. The difference of specificity between NBI plus AFB and AFB alone was significant (P < 0.01), but the difference of sensitivity between NBI plus AFB and AFB alone(P > 0.05) was not. The difference of specificity between NBI plus AFB and NBI alone was significant (P < 0.01), but the P value of specificity between NBI plus AFB and NBI was 0.03. CONCLUSION Combination of NBI and AFB could increase the specificity of lung cancer diagnosis compared to AFB alone.

Abstract
Background Our previous work demonstrated that persistent peripheral nociception (PPN) leads to synaptic plasticity and functional changes in the rat hippocampus. The protein kinase mTOR is a critical regulator of protein synthesis-dependent synaptic plasticity in the hippocampus as well as synaptic plasticity associated with central and peripheral pain sensitization. We examined the role of mTOR signaling in pain-associated entorhinal cortex (EC) - hippocampal synaptic plasticity to reveal possible cellular mechanisms underlying the effects of chronic pain on cognition and emotion. Results Subcutaneous injection of bee venom (BV) into one hind paw to induce PPN resulted in sustained (> 8 h) mTOR phospho-activation and enhanced phosphorylation of the mTOR target p70 S6 kinase (S6K) in the hippocampus. The magnitude and duration of long-term potentiation (LTP) in both EC - dentate gyrus (DG) and EC - CA1 synaptic pathways were elevated in BV-treated rats as measured by microelectrode array recording. Moreover, the number of potentiated synapses in the hippocampus was markedly upregulated by BV-induced PPN. Both elevated mTOR-S6K signaling and enhanced LTP induced by BV injection were reversed by systemic injection of the mTOR inhibitor rapamycin (RAPA). Rats injected with BV exhibited markedly reduced ambulation and exploratory activity in the open field (signs of depression and anxiety) compared to controls, and these effects were also reversed by RAPA. Conclusion We suggest that PPN-induced enhancement of synaptic plasticity in EC - hippocampal pathways and the behavioral effects of PPN are dependent on mTOR-S6K signaling.
