Long non-coding RNA CASC2 upregulates PTEN to suppress pancreatic carcinoma cell metastasis by downregulating miR-21. Cancer Cell Int 2019; 19:18. [PMID: 30675129 PMCID: PMC6335738 DOI: 10.1186/s12935-019-0728-y] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Accepted: 01/04/2019] [Indexed: 12/21/2022] Open
Abstract
Background The mechanism of pancreatic cancer metastasis remains poorly understood. Recently, lncRNA CASC2 has been demonstrated to be a tumor suppressor in various types of cancer. This study aimed to explore the mechanism of CASC2 in the regulation of pancreatic cancer metastasis. Methods The expression levels of CASC2 and miR-21 in pancreatic cells were detected by qRT-PCR. Using specific expression vectors, including mimics or shRNA, the expression levels of CASC2, miR-21 and PTEN in pancreatic cells were altered. The association between CASC2, miR-21 and PTEN was detected. Then, cell migration and invasion were assessed using the transwell assay. Results CASC2 expression was downregulated in the pancreatic cancer cell lines CAPAN-1, BxPC-3, JF305, PANC-1 and SW1990 compared with levels in normal human pancreatic HPDE6-C7 cells. CACS2 overexpression inhibited the migration and invasion of PANC-1 cells and significantly inhibited the expression of miR-21 and PTEN. MiR-21 was a direct target of CACS2. The overexpression of miR-21 significantly abolished the antimetastatic effects of CASC2 on PANC-1 cells. Moreover, the downregulation of PTEN significantly abolished the antimetastatic effects of CASC2. Conclusion CASC2 functions as a tumor suppressor in pancreatic cancer cells to inhibit tumor cell migration and invasion. Our work revealed a novel regulatory mechanism of the CASC2/miR-21/PTEN axis that may be important in pancreatic cancer.

Abstract
The skin has many important roles in dairy cattle, and skinfold thickness could be used as an indicator of body fat deposition. The objectives of this study were to estimate genetic parameters of skinfold thickness and to explore its association with body condition score (BCS) and milk production traits in a Chinese Holstein population. Skinfold thicknesses over the neck (STN) and the last rib (STR), BCS, and test-day records of milk production traits were available for 6,416 lactating Holstein cows in the summers of 2015 and 2016 in Beijing, China. Multi-trait animal models were used to estimate variance and covariance components using the DMU software. The average STN was 7.15 ± 1.28 mm, and the average STR was 11.76 ± 1.95 mm (mean ± standard deviation). Estimated heritability was 0.13 ± 0.03 for STN and 0.26 ± 0.04 for STR. We detected a high genetic correlation (0.79 ± 0.08; heritability ± standard error) between STN and STR. Genetic correlations between skinfold thickness and BCS were low to moderate: 0.18 between STR and BCS, and 0.33 between STN and BCS. Genetic correlations between skinfold thickness and milk yield, milk fat percentage, and milk protein percentage were negligible, ranging from -0.02 to 0.15. Collectively, skinfold thickness is characterized as a trait with moderate heritability. Skinfold thickness is sensitive to changes in body condition or fat deposition across parities and lactation stages in milking cows, and we confirmed the complementary nature of skinfold thickness and BCS genetically as well as phenotypically by comparing their changing trends throughout lactation and across lactations. The use of skinfold thickness, together with BCS, can assist in the monitoring of changes in body fat deposition to achieve higher management precision.

Abstract
Objectives Given the function of adiponectin (ADIPOQ) on the inflammatory condition of obesity and osteoarthritis (OA), we hypothesized that the ADIPOQ gene might be a candidate gene for a marker of susceptibility to OA. Methods We systematically screened three tagging polymorphisms (rs182052, rs2082940 and rs6773957) in the ADIPOQ gene, and evaluated the association between the genetic variants and OA risk in a case-controlled study that included 196 OA patients and 442 controls in a northern Chinese population. Genotyping was performed using the Sequenom MassARRAY iPLEX platform. Results The single nucleotide polymorphism (SNP) rs182052 was found to be potentially associated with knee OA risk (additive model: odds ratio = 1.38; 95% confidence interval 1.07 to 1.76; p = 0.012). Furthermore, a non-significant association was observed for rs182052 and body mass index with regard to OA risk in interaction analyses (p = 0.063). Similarly, no significant interaction was detected for rs182052 and age with regard to OA risk (p = 0.614). Conclusion These findings suggest that the SNP rs182052 in the ADIPOQ gene may potentially modify individual susceptibility to knee OA in the Chinese population. Further studies are warranted to investigate our findings in more depth. Cite this article: L. Jiang, X. Zhu, J. Rong, B. Xing, S. Wang, A. Liu, M. Chu, G. Huang.

Abstract
Objective: To explore the clinical value of 3D-DSA technology in the diagnosis and treatment guidance of hepatic artery chemoembolization. Methods: Liver cancer patients in the treatment groups were collected to receive 3D-DSA imaging guidance at the Affiliated Hospital of Xuzhou Medical University between March and May 2017. In addition, routine 2D-DSA imaging was selected for treatment-received group. Intra-operative blood vessels and tumor-like lesions were observed. The total exposure dose (CAK, unit mGy), cumulative irradiation intensity per unit area (DAP, unit mGy.cm2) and dosage of contrast agent (ml) were calculated separately for two groups of patients. The same senior physicians and technicians operated both groups of patients. Comparisons of measurement were analyzed by t-test and chi-square test was used for count data. Results: Data of twenty patients were collected from the two groups. Tumor location, target vessels structure and shape of development were clear in all patients in the treatment group. The control group had 17 cases of tumor development and the target vascular structure was clear in 16 cases. CAK mean treatment group was lower than control group (554.11 + 38.87) mGy and (644.53 + 26.70) mGy, and DAP mean treatment group was lower than the control group (125.25 + 7.54) mGy·cm(2) and (143.49 + 6.18) mGy·cm(2). The two groups were compared (P value < 0.05), and the differences were statistically significant. The mean dose of contrast agent in the two groups were lower than control group (64.42 + 3.92) ml, (70.79 + 4.47) ml, and the differences between the two groups were statistically significant (P < 0.05). Conclusion: 3D-DSA imaging technology can provide effective diagnosis and guidance in the treatment of hepatic artery chemoembolization. It can effectively reduce the radiation exposure dose and radiation intensity, and it is of high clinical value for interventional embolization of liver cancer.

Abstract
The lateral habenula (LHb) is a key brain region involved in the pathophysiology of depression. It is activated by stimuli associated with negative experiences and is involved in encoding aversive signals. Hyperactivity of LHb is found in both rodent models of depression and human patients with depression. However, little is known about the underlying molecular mechanisms. Here we show that in LHb neurons, p11, a multifunctional protein implicated in depression, is significantly upregulated by chronic restraint stress. Knockdown of p11 expression in LHb alleviates the stress-induced depression-like behaviors. Moreover, chronic restraint stress induces bursting action potentials in LHb neurons, which are abolished by p11 knockdown. Overexpression of p11 in dopamine D2 receptor-containing LHb neurons of control mice induces depression-like behaviors. These results have identified p11 in LHb as a key molecular determinant regulating negative emotions, which may help to understand the molecular and cellular basis of depression.

Abstract
BACKGROUND Activated T cells and dendritic cells (DCs) occur in atherosclerotic plaques. Proprotein convertase subtilisin kexin 9 (PCSK9) targets the LDL-receptor (LDLR) and results in increased LDL levels. We here investigate immune effects of PCSK9 on OxLDL induced DC maturation and T-cell activation. METHODS T cells were isolated from carotid specimens of patients undergoing carotid endarterectomy or from peripheral blood of healthy individuals. Human peripheral blood monocytes were differentiated into DCs. Naïve T cells were cocultured with pretreated DCs. The effects of PCSK9 and its inhibition by silencing were studied. RESULTS OxLDL induced PCSK9 in DCs and promoted DC maturation with increased expressions of CD80, CD83, CD86 and HLA-DR and the scavenger receptors LOX-1 and CD36. T cells exposed to OxLDL-treated DCs proliferated and produced IFN-γ and IL-17, thus with polarization to Th1 and/or Th17 subsets. Silencing of PCSK9 reversed the OxLDL effects on DCs and T cells. DC maturation was repressed, and the production of TNF-α, IL-1β and IL-6 was limited, while TGF-β and IL-10 secretion and T regulatory cells were induced. OxLDL induced miRNA let-7c, miR-27a, miR-27b, miR-185. Silencing PCSK9 repressed miR-27a and to a lesser extent let-7c. PCSK9 silencing enhanced SOCS1 expression induced by OxLDL. Experiments on T cells from carotid atherosclerotic plaques or healthy individuals showed similar results. CONCLUSIONS We demonstrate immunological effects of PCSK9 in relation to activation and maturation of DCs and plaque T cells by OxLDL, a central player in atherosclerosis. This may directly influence atherosclerosis and cardiovascular disease, independent of LDL lowering.

Abstract
The forensic fingerprint community has faced increasing amounts of criticism by scientific and legal commentators, challenging the validity and reliability of fingerprint evidence due to the lack of an empirically demonstrable basis to evaluate and report the strength of the evidence in a given case. This paper presents a method, developed as a stand-alone software application, FRStat, which provides a statistical assessment of the strength of fingerprint evidence. The performance was evaluated using a variety of mated and non-mated datasets. The results show strong performance characteristics, often with values supporting specificity rates greater than 99%. This method provides fingerprint experts the capability to demonstrate the validity and reliability of fingerprint evidence in a given case and report the findings in a more transparent and standardized fashion with clearly defined criteria for conclusions and known error rate information thereby responding to concerns raised by the scientific and legal communities.

Abstract
BACKGROUND Hepatorenal syndrome is a fatal complication of advanced cirrhosis. Terlipressin is the most widely used treatment method, however, the therapy effects remain inconsonant. We aim to systematically assess the safety and efficacy of terlipressin for hepatorenal syndrome. METHODS We conducted a systematic review and meta-analysis. Randomized controlled trials involving terlipressin for hepatorenal syndrome were included in a systematic literature search. Two authors independently assessed the studies for inclusion and extracted the data. A meta-analysis was conducted to estimate the safety and efficacy of terlipressin for hepatorenal syndrome. RESULTS A total of 18 randomized controlled trials including 1011 patients were included. Hepatorenal syndrome reverse rate was 42.0% in the terlipressin group and 26.2% in the non-terlipressin group. Terlipressin had greater hepatorenal syndrome reverse rate and renal function improvement rate than placebo and octreotide in the management of HRS. Comparing to norepinephrine, terlipressin had similar efficacy, but with more adverse events. No significant difference of the efficacy was found between terlipressin and dopamine treatment. The subgroup analysis for type 1 HRS had the above same results, except that the adverse events were not significant different between norepinephrine group and terlipressin group. CONCLUSIONS Terlipressin was superior to placebo and octreotide for reversal of hepatorenal syndrome and improving renal function, but it had no superiority comparing to norepinephrine.

Abstract
BACKGROUND A link between moral injury (i.e., the psychological distress caused by perceived moral transgressions) and adverse mental health outcomes (AMHO) has been recently proposed. However, the prevalence of exposure to morally injurious events and the associated risk of experiencing AMHO remains understudied. METHOD The impact of exposure to potentially morally injurious experiences (PMIEs) was explored in relation to past-year PTSD and MDD, using the 2013 Canadian Armed Forces Mental Health Survey dataset of Afghanistan mission deployed regular force and reserve personnel. A series of logistic regressions were conducted, controlling for relevant sociodemographic, military, deployment, and trauma-related variables. RESULTS Over half of the deployed personnel endorsed at least one PMIE. Several demographic and military variables were associated with exposure to PMIEs. Those exposed to PMIEs demonstrated a greater likelihood of having past-year PTSD and MDD; feeling responsible for the death of Canadian or ally personnel demonstrated the strongest association with PTSD and MDD. Mental health training was not a moderator for PMIE exposure and AMHO. CONCLUSIONS Exposure to PMIEs during deployments is common and represents an independent risk factor for past-year PTSD and MDD. Improved training that targets moral-ethical dilemmas and treatment interventions that address moral injury expressions is warranted.

Abstract
Collagen VI-related myopathy, caused by pathogenic variants in the genes encoding collagen VI, represents a clinical continuum from Ullrich congenital muscular dystrophy (UCMD) to Bethlem myopathy (BM). Clinical data of 60 probands and their family members were collected and muscle biopsies of 26 patients were analyzed. COL6A1, COL6A2 and COL6A3 exons were analyzed by direct sequencing or next generation sequencing (NGS). Sixty patients were characterized by delayed motor milestones, muscle weakness, skin and joint changes with 40 UCMD and 20 BM. Muscle with biopsies revealed dystrophic changes and showed completely deficiency of collagen VI or sarcolemma specific collagen VI deficiency. We identified 62 different pathogenic variants in these 60 patients, with 34 were first reported while 28 were previously known; 72 allelic pathogenic variants in COL6A1 (25/72, 34.7%), COL6A2 (33/72, 45.8%) and COL6A3 (14/72, 19.4%). We also found somatic mosaic variant in the parent of 1 proband by personal genome machine amplicon deep sequencing for mosaicism. Here we provide clinical, histological and genetic evidence of collagen VI-related myopathy in 60 Chinese patients. NGS is a valuable approach for diagnosis and accurate diagnosis provides useful information for genetic counseling of related families.

Prevalence of transmitted drug resistance among HIV-1 treatment-naive patients in Beijing. Epidemiol Infect 2018; 146:339-344. [PMID: 29345606 PMCID: PMC9134542 DOI: 10.1017/s0950268817003016] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2017] [Revised: 11/01/2017] [Accepted: 11/14/2017] [Indexed: 11/07/2022] Open
Abstract
To optimise patients' outcomes and gain insight into transmitted drug resistance (TDR) among human immunodeficiency virus (HIV)-1 treatment-naive patients in Beijing, the prevalence of TDR was assessed. Demographic and clinical data of 1241 treatment-naive patients diagnosed between April 2014 and February 2015 were collected. TDR was defined using the Stanford University HIV drug resistance mutations database. The risk factors were evaluated by multi-logistic regression analysis. Among 932 successfully amplified cases, most were male (96.78%) and infected through men having sex with men (91.74%). Genotype were CRF01_AE (56.44%), B (20.60%), CRF07_BC (19.96%), C (1.61%) and other genotypes (1.39%). The overall prevalence of TDR was 6.12%. Most frequent mutations occurred in non-nucleoside reverse transcriptase inhibitors (NNRTIs) (3.11%), followed by protease inhibitors (PIs) (2.25%) and nucleoside reverse transcriptase inhibitors (NRTIs) (1.32%). Furthermore, HIV-1 genotype was associated with high risk of resistance, in which genotype C and other genotype may have higher risk for resistance. The prevalence among treatment-naive patients in Beijing was low. Resistance to NNRTIs was higher than with PIs or NRTIs. Continuous monitoring of regional levels of HIV-1 TDRs would contribute to improve treatment outcomes and prevent failures.

Abstract
BACKGROUND Postoperative liver failure remains the main complication and predominant cause of hepatectomy-related mortality for patients undergoing liver resection. AIM Our aim is to investigate whether immediate postoperative Fibrosis-4 could predict postoperative liver failure. METHODS We retrospectively enrolled 1353 consecutive hepatocellular carcinoma patients undergoing radical resection. The characteristics and clinical outcomes were compared between patients with high and low immediate postoperative Fibrosis-4. Risk factors for hepatic failure were evaluated by univariate and multivariate analysis. RESULTS Using a receiver operating characteristic curve, immediate postoperative Fibrosis-4 showed good prediction ability for postoperative liver failure (AUROC=0.647, P<0.001). With the optimal cut-off value of 5.9, the high postoperative Fibrosis-4 group (Fibrosis-4<5.9) had higher postoperative complication (39.1% vs 28.6%, P<0.001), mortality (2.8% vs 0.6%, P<0.001) and liver failure (13.9% vs 6.2%, P<0.001). In addition, patients with high Fibrosis-4 had worse and delayed recovery of liver function. By univariate and multivariate analysis, Fibrosis-4, as well as liver removed volume, total bilirubin and albumin was identified as independent risk factor for postoperative liver failure. CONCLUSIONS Immediate postoperative Fibrosis-4 showed good prediction ability for postoperative liver failure, and required measure should be taken to prevent liver failure when high postoperative Fibrosis-4 appeared.

Abstract
The identification of network targets is one of the core issues used to reveal the molecular mechanism of traditional Chinese medicine (TCM) and is also the grand challenge of modernization of TCM. In this study, a protein–protein interaction (PPI) network was constructed based on the integration of network pharmacology and metabolomics, which was used as an effective approach to elucidate the relationship between disease pathway proteins and the targets of active small-molecule compounds. The intermolecular transfer process of the drug effect of active compounds in Salvia miltiorrhiza (SM) was revealed and visualized using the PPI network. Our study indicates that PTGS2 was the most important disease protein regulated by the active compounds in SM. Furthermore, the drug targets that can be linked to PTGS2 were regarded as direct targets and the direct targets of the active compounds were identified, respectively. Western blot and co-immuno precipitation (Co-IP) were used to verify the results of the network analysis and reveal the intermolecular transfer process of the effect of Tan IIA. Biological validation revealed that Tan IIA-EDN1-PTGS2-anandamide was a major intervention way of Tan IIA on early atherosclerosis (AS). This work provides a new perspective for the discovery of drug targets and the specific approaches regulated by the active compounds in SM on disease pathway proteins, which is beneficial for understanding the mechanism of action of bioactive compounds and expanding their clinical applications. The discovery of drug targets and the specific regulatory manner of active compounds based on a PPI network.![]()

Abstract
Objective: To investigate the efficacy and clinical value of transcatheter arterial chemoembolization (TACE) combined with ultrasound-guided microwave ablation for the treatment of liver cancer in special sites. Methods: The patients with liver cancer in special sites (the liver cancer was adjacent to the gallbladder, dome of diaphragm, gastrointestinal tract, heart, great vessels, and portal vein, with the shortest distance from the tumor to the organ/lumen < 0.5 cm ) were enrolled as treatment group, and the patients with primary liver cancer in normal sites treated in our hospital during the same period were randomly enrolled as control group. They underwent TACE combined with ultrasound-guided microwave ablation. The 6-month, 12-month, 18-month and 24-month survival rates of the patients in two groups were analyzed. Results: The clinical data of 40 patients with liver cancer in special sites, including 9, 7, 5, 11, 3, 3, and 2 patients with liver cancer adjacent to the gallbladder, dome of diaphragm, gastrointestinal tract, portal vein, hepatic vein, inferior vena cava, and heart, respectively, and another 40 patients in control group were collected in the study. The negative rate of alpha-fetoprotein (AFP) was 83.3% in the treatment group and 82.8% in the control group. The 6-month, 12-month, 18-month, and 24-month survival rates were 100.0%, 95.0%, 90.0%, and 80.0%, respectively, in the treatment group, and 100.0%, 97.5%, 92.5%, and 85.0%, respectively, in the control group. Conclusion: TACE combined with ultrasound-guided microwave ablation is as effective for liver cancer in special sites as for those in normal sites, with high safety, and is feasible in clinical application.

Abstract
Drug resistant tuberculosis (TB) infections are on the rise and antibiotics that inhibit Mycobacterium tuberculosis through a novel mechanism could be an important component of evolving TB therapy. Protein kinase A (PknA) and protein kinase B (PknB) are both essential serine-threonine kinases in M. tuberculosis. Given the extensive knowledge base in kinase inhibition, these enzymes present an interesting opportunity for antimycobacterial drug discovery. This study focused on targeting both PknA and PknB while improving the selectivity window over related mammalian kinases. Compounds achieved potent inhibition (Ki ≈ 5 nM) of both PknA and PknB. A binding pocket unique to mycobacterial kinases was identified. Substitutions that filled this pocket resulted in a 100-fold differential against a broad selection of mammalian kinases. Reducing lipophilicity improved antimycobacterial activity with the most potent compounds achieving minimum inhibitory concentrations ranging from 3 to 5 μM (1-2 μg/mL) against the H37Ra isolate of M. tuberculosis.

Abstract
BACKGROUND The impact of excess weight on cardiovascular disease risk in type 1 diabetes patients is unclear. OBJECTIVE This study examined associations of BMI and body composition with cardiovascular risk factors in youth followed prospectively for 18 months. METHODS The sample includes youth with type 1 diabetes (N = 136, baseline age = 12.3 ± 2.5y, glycated hemoglobin = 8.1 ± 1.1%) participating in an 18-month behavioral nutrition intervention trial. BMI, body composition (by dual energy x-ray absorptiometry), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C); triglycerides (TG), c-reactive protein (CRP), 8-iso-prostaglandin-F2alpha (8-iso-PGF2α), adiponectin and systolic and diastolic blood pressure (SBP and DBP, respectively) were assessed at clinic visits every 6 months. Random effects regression models for repeated measures estimated associations of time-varying BMI and body composition with time-varying cardiovascular risk factors, adjusted for treatment assignment and covariates. RESULTS There was no intervention effect on cardiovascular risk factors. Percent body fat was positively associated with TG, LDL-C, CRP, SBP and DBP, while trunk fat mass and trunk %fat were associated positively with TG, LDL-C, CRP, SBP and DBP, and inversely with HDL-C. Higher BMI was associated with greater TG, CRP, SBP and DBP and lower HDL-C. BMI and body composition indicators were unrelated to 8-iso-PGF2α and adiponectin. CONCLUSIONS Excess adiposity is associated with increased cardiovascular risk factors in this sample of youth with type 1 diabetes. Non-significant associations with adiponectin and 8-iso-PGF2α suggest potential differences from the general population in the role of adiposity in cardiovascular health.

Abstract
Implanting artificial biomaterial implants into alveolar bone defects with individual shape and appropriate mechanical strength is still a challenge. In this study, bioceramic scaffolds, which can precisely match the mandibular defects in macro and micro, were manufactured by the 3-dimensional (3D) printing technique according to the computed tomography (CT) image. To evaluate the stimulatory effect of the material substrate on bone tissue regeneration in situ in a rabbit mandibular alveolar bone defect model, implants made with the newly developed, mechanically strong ~10% Mg-substituted wollastonite (Ca90%Mg10%SiO3; CSi-Mg10) were fabricated, implanted into the bone defects, and compared with implants made with the typical Ca-phosphate and Ca-silicate porous bioceramics, such as β-tricalcium phosphate (TCP), wollastonite (CaSiO3; CSi), and bredigite (Bred). The initial physicochemical tests indicated that although the CSi-Mg10 scaffolds had the largest pore dimension, they had the lowest porosity mainly due to the significant linear shrinkage of the scaffolds during sintering. Compared with the sparingly dissolvable TCP scaffolds (~2% weight loss) and superfast dissolvable (in Tris buffer within 6 wk) pure CSi and Bred scaffolds (~12% and ~14% weight loss, respectively), the CSi-Mg10 exhibited a mild in vitro biodissolution and moderate weight loss of ~7%. In addition, the CSi-Mg10 scaffolds showed a considerable initial flexural strength (31 MPa) and maintained very high flexural resistance during soaking in Tris buffer. The in vivo results revealed that the CSi-Mg10 scaffolds have markedly higher osteogenic capability than those on the TCP, CSi, and Bred scaffolds after 16 wk. These results suggest a promising potential application of customized CSi-Mg10 3D robocast scaffolds in the clinic, especially for repair of alveolar bone defects.

Abstract
OBJECTIVE Hyponatremia is one of the most frequently encountered electrolyte disorder in small cell lung cancer (SCLC) patients. It was shown that some SCLC cell lines could produce atrial natriuretic peptide (ANP) and arginine vasopressin (AVP). The aim of the study was to assess the secretion of ANP, AVP and their relative contributions to hyponatremia in SCLC patients, especially in patients with brain metastases. PATIENTS AND METHODS In total, 194 SCLC patients including 51 patients with brain metastases were collected. The levels of ANP and AVP were measured with radioimmunoassay kits. And then their associations with serum sodium were investigated. The progression-free survival (PFS) was compared between the hyponatremia group and the normal serum sodium group. RESULTS Serum sodium was negatively correlated with the plasma levels of ANP (r=-0.171, p=0.017) and AVP (r = -0.244, p=0.001) in all SCLC patients. In the brain metastatic subgroup, there was also a negative correlation between serum sodium and ANP (r=-0.399, p=0.004), while there was no correlation between serum sodium and AVP (r=-0.232, p=0.101). The occurrence rate of hyponatremia (serum sodium values below 135 mmol/l) in patients with brain metastases (21/51, 41.18%) was higher than that in patients without brain metastases (37/143, 25.87%) (p=0.040). The progression-free survival (PFS) in the hyponatremia group was significantly shorter than that in patients of the group without hyponatremia (p=0.010). Moreover, compared with patients which regained normal serum sodium after the treatment, the PFS of patients still with hyponatremia after the treatment was significantly shorter (p=0.049). CONCLUSIONS ANP might play a leading role in the formation of hyponatremia of SCLC patients with brain metastases. Correcting hyponatremia timely and appropriately could improve SCLC patients' prognosis.
