Abstract
OBJECTIVES The aim of the present study is to investigate the associations between the Asian Working Group for Sarcopenia (AWGS) sarcopenic definition, and its individual criteria, and risk of cardiovascular disease (CVD) and all-cause mortality in the Chinese elderly. METHODS Longitudinal analysis of 1,264 participants aged 60 years or older at baseline (2013-2014) living in suburban areas, China. Sarcopenia was defined according to the recommended algorithm of AWGS. Muscle mass was measured by a direct segmental multifrequency bioelectrical impedance analysis. Muscle strength was assessed by handgrip strength, and physical performance measured via usual walking speed. RESULTS Cox proportional hazard models were used to assess the risk of CVD and all-cause mortality. After 40 months of follow-up, forty-eight deaths (4.2%) died in this cohort. The mortality rate with sarcopenia was 4.7% in men and 3.8% in women. After adjusting for potential confounders, the risk of all-cause death was 4.15 times higher in subjects with sarcopenia. Furthermore, low muscle mass (HR: 2.62, 95% CI 1.34-5.13) and low grip strength (HR: 5.79; 95% CI 2.28-14.71), but not walking speed, were found to be significantly associated with all-cause mortality. Risk of CVD mortality was significantly greater in sarcopenia. Low grip strength and low walking speed were associated with 11 times (HR: 11.03, 95% CI 1.58-77.02) and 13 times (HR: 13.02; 95% CI 1.18-143.78) higher risk of CVD mortality. CONCLUSIONS Sarcopenia and components of sarcopenia were associated with greater CVD and all-cause mortality. Pertinent prevention or rehabilitation programs projects should look to promote healthy aging in different types of sarcopenia group.

Abstract
Neopterin is primarily synthesized and released by activated macrophages/monocytes upon stimulation with interferon-γ and is considered as a marker for macrophage activation. This study aimed to analyze the serum levels of neopterin in patients with dermatomyositis (DM) in association with clinical manifestations, laboratory data and patient prognosis. One hundred and eighty-two consecutive DM patients and 30 healthy controls were retrospectively enrolled into the study. Serum levels of neopterin were significantly increased in DM patients compared to healthy controls (P < 0·001). High serum neopterin levels were associated with anti-melanoma differentiation-associated gene (MDA5) antibody, rapidly progressive interstitial lung disease (RP-ILD) and characteristic DM cutaneous involvement. Longitudinal assessment of serum samples revealed that the serum neopterin levels were closely correlated with disease severity (β = 30·24, P < 0·001). In addition, a significant increase in serum neopterin concentration of non-survivors was observed when compared to that of survivors (P < 0·001). Receiver operator characteristic curves showed that serum neopterin could distinguish non-survivors and survivors at an optimal cut-off level of 22·1 nmol/l with a sensitivity and specificity of 0·804 and 0·625, respectively (P < 0·001). Kaplan-Meier survival curves revealed that DM patients with serum neopterin > 22·1 nmol/l had a significantly higher mortality compared to the patient group with serum neopterin < 22·1 nmol/l (log-rank P < 0·001). Multivariate regression analysis identified high serum neopterin concentration to be an independent risk factor for poor prognosis in DM (adjusted hazard ratio = 4·619, 95% confidence interval = 2·092-10·195, P < 0·001). In conclusion, increased serum levels of neopterin were significantly associated with RP-ILD and reduced survival in DM patients, suggesting it as a promising biomarker in disease evaluation of DM.

Abstract
Objective: To study the clinicopathological characteristics of lung salivary gland-type tumors (SGT), and to compare with the corresponding primary SGT in salivary glands. Methods: Twenty-three cases of lung SGT were retrieved from the files of Peking University First Hospital from January 2004 to September 2018. The morphology, immunophenotype, genotype and outcome of these cases were analyzed. Results: The 23 patients included 13 males and 10 females, with age range of 13-79 years (median 54 years). There were 11 cases of adenoid cystic carcinoma, 10 cases of mucoepidermoid carcinoma (MEC), one case each of clear cell carcinoma and myoepithelioma. The morphology and immunophenotype of lung SGT were very similar to their counterparts in salivary gland. MYB rearrangement was detected in one of 11 adenoid cystic carcinomas. MAML2 rearrangement was detected in all the MECs. EWSR1 rearrangement was detected in the one case of clear cell carcinoma. Of patients with adenoid cystic carcinoma, the survival time was more than 60 months (three cases), 52 months (one case), and 12-36 months (three cases). There was no recurrence and death in seven cases of MEC with follow-up results. One case of clear cell carcinoma recurred after 52 months of follow-up. Conclusions: Although the SGT of lung and their counterparts in salivary gland are very similar in their morphology, immunophenotype, genotype and prognosis, there are also some differences between each other. MYB rearrangement can be detected in most adenoid cystic carcinomas of salivary gland, but rarely in lung adenoid cystic carcinoma. The prognosis of patients with lung MEC is better than that of patients with salivary gland MEC, while the prognosis of patients with lung adenoid cystic carcinoma is worse than that of patients with salivary gland adenoid cystic carcinoma.

Abstract
OBJECTIVE Circular RNAs (circRNAs) have emerged as crucial regulators for tumor progression. However, the effects of circRNAs are not entirely clear in cervical cancer (CC). The objective of this study was to investigate the function and regulation mechanism of circular RNA SMARCA5 (circSMARCA5, also named hsa_circ_0001445) in cervical cancer. PATIENTS AND METHODS circSMARCA5 and miR-620 expressions were analyzed by qRT-PCR assay. The cell proliferation, cell cycle, migration, invasion abilities were measured by CCK-8 and colony formation, Flow cytometry, Wound-healing and transwell assays. In addition, the interaction between circSMARCA5 and miR-620 was accessed by luciferase reporter assay. RESULTS The results indicated that circSMARCA5 was downregulated in CC; overexpression of circSMARCA5 inhibited CC cell proliferation, migration and invasion, and induced cell cycle arrest. In addition, we found that circSMARCA5 could bind to miR-620 and significantly downregulated its expression. Furthermore, the results revealed that circSMARCA5 suppressed proliferation and invasion by miR-620 in CC. CONCLUSIONS We suggested that circSMARCA5/miR-620 regulatory axis is involved in the development of CC and may serve as a potential therapy target.

Abstract
Objective: By comparing and analyzing the differential sites of single nucleotide polymorphisms (SNP) between pregnant women with hypothyroidism and normal controls, the possible pathogenesis of hypothyroidism during pregnancy was explored. Methods: A total of 53 pregnant women with hypothyroidism during pregnancy from January 2018 to October 2018 were enrolled. A total of 50 pregnant women who underwent concurrent delivery and matched age with the case group were selected. Whole blood scans were performed on blood samples from two groups of subjects using the Illumina ASA chip to analyze the SNP with significant differences between the two groups. The human genome database hg19_dbsnp_version150 was employed to locate related genes. The association of related genes with thyroid dysfunction and pregnancy complications were analyzed. Results: A total of 13 SNPs were found in the study: rs4668077 (P=2.87E-05) in CERS6, rs6717546 (P=5.92E-05) in UGT1A1, rs1965358(P=7.78E-05) in CASR, rs916801 (P=9.22E-05) near CXCL14, rs6886845 (P=8.67E-05)near MAT2B, rs76245053 in GRIK2 (P=2.07E-05), rs6977642 (P=2.10E-05)in HDAC9, rs6949597 (P=3.68E-05) near ATXN7L1, rs11186331 (P=2.08E-05) in HTR7, rs2415551 (P=4.53E-05) near FBXO33, rs75850124 (P=9.24E-05) and rs76519339 (P=9.24E-05)in MIR4527, rs1014971 (P=3.24E-05) near CBX6 were statistically significant in the hypothyroidism group compared with the control group. Conclusions: The related gene UGT1A1 is related to the metabolism of thyroxine in the liver. CASR, CXCL14 and CBX6 are related to reproductive ability. CXCL14, CASR, HBAC9 and CERS6 are related to metabolic syndrome, and GRIK2, HTR7 and FBOX33 are related to neuropsychiatric diseases. Abnormal serum thyroxine levels during pregnancy may be associated with abnormal metabolism of thyroxine caused by UGT1A1 mutation. Genes associated with reproduction, metabolism, and neuropsychiatric disorders suggest a pathogenic link between hypothyroidism and infertility, metabolic syndrome, and neuropsychiatric disorders.

Abstract
Objective: To construct the recombinant adenoviral containing fructose 1, 6-biphosphatase 1 (FBP1), and to investigate whether FBP1 has effect on autophagy and proliferation in liver cancer cells (HepG2). Methods: FBP1 cDNA sequence was amplified by PCR and cloned in adenovirus vector pAdTrack-TO4, and then recombinant adenovirus plasmid pAdTrack-FBP1 was constructed. The recombinant adenovirus plasmid was transfected into HEK293 cells by Lipofectamine 3000. High-titer of recombinant adenovirus AdFBP1 was obtained by packaging and amplification. HepG2 cells were infected with recombinant adenovirus AdFBP1, and the Mock and AdGFP group were set at the same time. Western blot and confocal laser scanning microscopy were used to observe the effect of FBP1 on the level of autophagy in hepatocellular carcinoma cells, and the effect of FBP1on the proliferation was observed by MTS and colony formation assay. A t-test and one-way ANOVA were used to compare the mean between group. Results: A high-titer recombinant adenovirus FBP1 was successfully constructed. Western blot and confocal laser scanning microscopy showed that the level of autophagy in AdFBP1 group was significantly lower than that in AdGFP group. Western blot results showed that LC3-II protein expression level in AdGFP was 1.10 ± 0.10 and 0.30 ± 0.01 in AdFBP1 group, F = 90.36, P < 0.01. Confocal laser scanning microscopy analysis showed that the average number of autophages in AdGFP was 28.33 ± 1.53 and 12.33 ± 1.53 in AdFBP1group, F = 97.40, P < 0.01. In addition, the results of colony formation assay and MTS assay showed that the proliferation of liver cancer cells in the AdFBP1 group was significantly inhibited compared with the AdGFP group. The results of colony formation showed that the cell clones in the AdGFP group was 65.66 ± 2.57 and 34.00 ± 2.00 in AdFBP1 group, F = 141.50, P < 0.01. MTS results showed that the absorbance of AdGFP group at 96h was 39.13 ± 2.21 and 30.61 ± 3.33 in AdFBP1 group, F = 7.80, P < 0.05. Conclusion: FBP1 inhibited the autophagy and proliferation in liver cancer cells (HepG2).

Abstract
OBJECTIVES To investigate the fetal adverse pregnancy outcomes (APOs) and the predictive value of umbilical arterial Doppler ultrasonography in the third trimester in pregnant women with lupus nephritis (LN). METHODS A retrospective cohort study enrolling 203 LN patients from 2007 to 2017 was performed. Ultrasonic parameters were recorded. RESULTS Fetal APOs occurred in 103 patients (103/203, 50.7%). Sixty-six pregnancies (66/203, 32.5%) ended with preterm births. The incidence rate of intrauterine growth restriction (IUGR) was 18.2% (37/203). Fetal distress was noted in 23 pregnancies (23/203, 11.3%). All the Doppler parameters elevated in patients with IUGR, fetal distress, and composite conditions. Resistance index (RI) indicated the highest risk of IUGR and composite APOs. The cutoff values were 0.66 and 0.67, respectively. Sensitivities were 51.4% and 33.7%, and specificities were 87.4% and 92.1%. Peak velocity of the umbilical arteries at end-systole (Vmax, abbreviated as S) to that at end-diastole (Vmin, abbreviated as D) (S/D) ratio was also a best predictor for IUGR, with the optimal cutoff value of 2.88. Sensitivity and specificity were comparable with RI. Pulsatility index (PI) over 0.84 was an ideal indicator for fetal distress with an optimal combination of sensitivity (89.5%) and specificity (51.6%). CONCLUSIONS Fetal complications were frequent in patients with LN. Umbilical arterial Doppler ultrasonography was a useful measure to predict late IUGR, fetal distress, and the composite APOs.

Abstract
Objective: To study the clinical characteristics of outpatients with hand, foot and mouth disease (HFMD) caused by different serotypes of enteroviruses. Methods: This was a prospective study. From February 2017 to March 2018, 563 outpatients with HFMD were enrolled by systematic sampling in the Department of Infectious Diseases, Henan Children's Hospital. Throat swabs were collected to determine the serotypes via PCR. Demographic, clinical, and laboratory data were collected by standard questionnaire. All cases were followed up twice at 2 and 9 weeks after the initial outpatient visit through telephone interview. A total of 563 cases were enrolled and 555 (98.6%) cases were positive for human enteroviruses, including 338 (60.9%) males. Analyses were stratified by enterovirus serotypes, Chi square test or Fisher's exact test, Rank sum test was used for comparison among different groups. Results: The age of 555 cases was 24.2 (16.4, 41.3) months. Among them 44.0% (224 cases) were identified as coxsackievirus (CV)-A6, while 189 cases, 35 cases, 14 cases and 73 cases were identified as CV-A16, enterovirus (EV)-A71, CV-A10 and other serotypes, respectively. Fever (≥37.5 ℃) was present in 51.4% (285/555) of laboratory confirmed cases. The proportions of fever in cases of CV-A6 (68.9%(168/244)) and CV-A10 (12/14) were significantly higher than those in cases of CV-A16 (31.7%(60/189),χ(2)=57.344,14.313,both P=0.000), other serotypes (43.8%(32/73),χ(2)=15.101 and 8.242, P=0.000 and 0.004) and EV-A71 (37.1%(13/35), χ(2)=13.506 and 9.441, P=0.000 and 0.002) respectively. There was no significant difference between CV-A6 and CV-A10 in presentation of fever (χ(2)=1.785, P=0.182). There were 359 cases (64.7%) with eruptions in mouth, hands, feet and buttocks. Cases infected with EV-A71 had the highest proportions (74.3%(26/35)) of rash emerging simultaneously in mouth, hands, feet, and buttocks. The proportion in cases of CV-A16, CV-A6, CVA10 and other serotype were 73.5% (139/189), 61.9% (151/244), 7/14 and 49.3% (36/73), respectively. The proportion of rash on other parts of body, such as face, limbs or torso in cases infected with CV-A6 (16.8% (41/244)) was the higherest and the proportion in cases of CV-A16, EV-A71, CV-A10 or other serotypes were 8.5% (16/189) , 5.7% (2/35) , 1/14, 6.8% (5/73) , respectively. None of these cases developed serious complications. Desquamation occurred in 45.5% (179/393) cases 7.5 (5.0, 9.0) days after disease onset and 13.5% (53/393) cases showed onychomadesis 31.0 (18.0, 33.5) days after disease onset. The proportion of desquamation and onychomadesis associated with CV-A6 (64.2% (95/148) and 31.8% (47/148)) was significantly higher than CV-A16 (31.8% (49/154) and 1.3% (2/154), χ(2)=33.601 and 52.482, both P=0.000) and other serotypes (38.0%(19/50) and 6.0%(3/50),χ(2)=10.236 and 12.988, P=0.001 and 0.000). Desquamation appeared more in cases of CV-A6 than in cases of CV-A10 (2/11,χ(2)=9.386, P=0.002), with the proportion of onychomadesis higher in CV-A6 than in EV-A71 (3.3% (1/30),χ(2)=11.088, P=0.001). Conclusion: Clinical manifestation such as fever, rash emerging parts, desquamation and onychomadesis are different among outpatient HFMD cases infected with CV-A16, CV-A6, EV-A71, CV-A10 and other enteroviruses.

Abstract
Objective: To explore the gene mutation characteristics and detailed clinical presentations of hyperglycemia caused by GCK mutations in 10 patients. Methods: The clinical and follow-up data of 10 patients with hyperglycemia caused by mutation of GCK gene were reviewed. The patients were ascertained between January 1, 2014 and August 31, 2018 at the Department of Pediatrics, the First Affiliated Hospital of Zhejiang University and Ningbo Women & Children's Hospital. Clinical data were collected, including age, gender, main complaint, family history, fasting blood glucose, fasting blood insulin, 2-hour blood glucose, 2-hour blood insulin after oral glucose tolerance test, glycosylated hemoglobin, anti-glutamic acid decarboxylase antibody and body mass index. Mutations of GCK gene were detected by Sanger sequencing or high-throughput sequencing of diabetes-related genes in the patients and their family members. Results: There were ten patients, 8 of them were male, 2 were female.The ages at diagnosis varied between 4.7 to 12.3 years. The patients usually did not have obvious clinical symptoms of diabetes mellitus. Most of them were unexpectedly found to have hyperglycemia and with impaired glucose metabolism in three consecutive generations. The fasting blood glucose of patients was 6.8-7.7 mmol/L, 2-hour postprandial blood glucose was 7.8-11.6 mmol/L. Fasting blood insulin was 0.5-8.5 mU/L, glucose tolerance test results showed that 2 h postprondial blood insulin was 1.3-55.4 mU/L. The level of glycosylated hemoglobin was 6.1%-6.8%. Anti-glutamic acid decarboxylase antibody was negative in all patients. The GCK mutations identified in patients and one of their parents were located at exon5 (4 cases), exon9 (2 cases), exon2 (1 case), exon4 (1 case), exon6 (1 case) and exon7 (1 case). Conclusions: Most of the hyperglycemia patients caused by GCK mutations did not have typical clinical symptoms of diabetes. The fasting blood glucose was slightly elevated. Abnormal glucose tolerance test results were found in all 10 patients. Three consecutive generations of family had impaired glucose metabolism. GCK mutations located at exon 5 were common in 10 cases. There was no correlation between type of mutations and plasma glucose levels in domestic and international researches. When fasting glucose was found abnormal in clinic, a complete family history should be taken and the GCK gene should be sequenced to confirm the diagnosis in time.

Abstract
OBJECTIVE To investigate the correlation of osteoporosis (OP) with matrix metalloproteinase-1 (MMP-1) gene polymorphism. PATIENTS AND METHODS A total of 199 patients as observation group (OP) and 180 healthy subjects (control group) were enrolled in the study, and the general data, the expression levels of serum calcium, serum phosphate and MMP-1 were collected and determined. The bone mineral density was determined using a bone sonometer, and the method of TaqMan-MGB probe was adopted for the detection of gene polymorphism of MMP-1 rs494379. RESULTS The level of serum calcium and bone mineral density were lower in observation group than those in control group (p>0.05), while the levels of serum phosphate and MMP-1 were higher than those in control group (p>0.05). There were differences in rs494379 genotype and allele in MMP-1 gene between the two groups (p<0.05). In the analysis of the genetic model, the dominant models between the two groups were different (p<0.05), while there were no differences in the recessive model and additive model (p>0.05). The MMP-1 level was higher in rs494379 AA genotype than that in GG, GT genotype in MMP-1 gene. CONCLUSIONS Gene polymorphism of MMP-1 rs494379 has a correlation with the occurrence of OP.

Abstract
Abstract
Background
Postoperative complications have a great impact on the postoperative course and oncological outcomes following major cancer surgery. Among them, infective complications play an important role. The aim of this study was to evaluate whether postoperative infective complications influence long-term survival after liver resection for hepatocellular carcinoma (HCC).
Methods
Patients who underwent resection with curative intent for HCC between July 2003 and June 2016 were identified from a multicentre database (8 institutions) and analysed retrospectively. Independent risk factors for postoperative infective complications were identified. After excluding patients who died 90 days or less after surgery, overall survival (OS) and recurrence-free survival (RFS) were compared between patients with and without postoperative infective complications within 30 days after resection.
Results
Among 2442 patients identified, 332 (13·6 per cent) had postoperative infective complications. Age over 60 years, diabetes mellitus, obesity, cirrhosis, intraoperative blood transfusion, duration of surgery exceeding 180 min and major hepatectomy were identified as independent risk factors for postoperative infective complications. Univariable analysis revealed that median OS and RFS were poorer among patients with postoperative infective complications than among patients without (54·3 versus 86·8 months, and 22·6 versus 43·2 months, respectively; both P < 0·001). After adjustment for other prognostic factors, multivariable Cox regression analyses identified postoperative infective complications as independently associated with decreased OS (hazard ratio (HR) 1·20, 95 per cent c.i. 1·02 to 1·41; P = 0·027) and RFS (HR 1·19, 1·03 to 1·37; P = 0·021).
Conclusion
Postoperative infective complications decreased long-term OS and RFS in patients treated with liver resection for HCC.

J Endocrinol Invest 2019; 42:673-685. [PMID: 30387079 DOI: 10.1007/s40618-018-0968-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2018] [Accepted: 10/13/2018] [Indexed: 02/06/2023]
Abstract
PURPOSE Evidence showed that benign thyroid disease was one of the risk factors for thyroid cancer. However, the results of some studies were inconsistent and were previously meta-analyses of case-control studies. Therefore, we performed a meta-analysis of prospective studies to investigate the relationship between benign thyroid diseases and thyroid cancer risk. METHODS All eligible studies were identified via systematic searches of multiple literature databases. The combined RR (relative risk)/HR (hazard ratio) or SIR (standardized incidence ratio) with 95% confidence interval was calculated. Heterogeneity was assessed with the I2 test. Publication bias and subgroup analyses were also performed. RESULTS Twelve studies were eligible for inclusion in the meta-analysis. The pooled RR/HR of thyroid carcinoma in benign thyroid diseases was 4.39 (95% CI 3.22-5.55). The pooled SIR of thyroid carcinoma in benign thyroid diseases was 5.98 (95% CI 4.09-7.86). Subgroup analysis was performed using the type of benign thyroid diseases. Effect value was RR/HR: hyperthyroidism (RR/HR = 3.89, 95% CI = 1.69-6.08), hypothyroidism (RR/HR = 2.72, 95% CI = 1.04-4.41), and goiter (RR/HR = 22.18, 95% CI = 12.09-32.28). Effect value was SIR: hyperthyroidism (RR/HR = 5.96, 95% CI = 1.88-10.03), goiter (RR/HR = 7.65, 95% CI = 6.94-8.37), and thyroiditis (RR/HR = 3.25, 95% CI = 1.62-4.89). CONCLUSIONS Our study has shown that benign thyroid diseases might be associated with increased risk of thyroid cancer, especially in hyperthyroidism, hypothyroidism, and goiter. However, further investigation is needed to better understand the underlying biological mechanisms.

CAFs secreted exosomes promote metastasis and chemotherapy resistance by enhancing cell stemness and epithelial-mesenchymal transition in colorectal cancer. Mol Cancer 2019; 18:91. [PMID: 31064356 PMCID: PMC6503554 DOI: 10.1186/s12943-019-1019-x] [Citation(s) in RCA: 431] [Impact Index Per Article: 86.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2019] [Accepted: 04/10/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Cancer associated fibroblasts (CAFs) are key stroma cells that play dominant roles in tumor progression. However, the CAFs-derived molecular determinants that regulate colorectal cancer (CRC) metastasis and chemoresistance have not been fully characterized. METHODS CAFs and NFs were obtained from fresh CRC and adjacent normal tissues. Exosomes were isolated from conditioned medium and serum of CRC patients using ultracentrifugation method and ExoQuick Exosome Precipitation Solution kit, and characterized by transmission electronic microscopy, nanosight and western blot. MicroRNA microarray was employed to identify differentially expressed miRNAs in exosomes secreted by CAFs or NFs. The internalization of exosomes, transfer of miR-92a-3p was observed by immunofluorescence. Boyden chamber migration and invasion, cell counting kit-8, flow cytometry, plate colony formation, sphere formation assays, tail vein injection and primary colon cancer liver metastasis assays were employed to explore the effect of NFs, CAFs and exosomes secreted by them on epithelial-mesenchymal transition, stemness, metastasis and chemotherapy resistance of CRC. Luciferase report assay, real-time qPCR, western blot, immunofluorescence, and immunohistochemistry staining were employed to explore the regulation of CRC metastasis and chemotherapy resistance by miR-92a-3p, FBXW7 and MOAP1. RESULTS CAFs promote the stemness, epithelial-mesenchymal transition (EMT), metastasis and chemotherapy resistance of CRC cells. Importantly, CAFs exert their roles by directly transferring exosomes to CRC cells, leading to a significant increase of miR-92a-3p level in CRC cells. Mechanically, increased expression of miR-92a-3p activates Wnt/β-catenin pathway and inhibits mitochondrial apoptosis by directly inhibiting FBXW7 and MOAP1, contributing to cell stemness, EMT, metastasis and 5-FU/L-OHP resistance in CRC. Clinically, miR-92a-3p expression is significantly increased in CRC tissues and negatively correlated with the levels of FBXW7 and MOAP1 in CRC specimens, and high expression of exosomal miR-92a-3p in serum was highly linked with metastasis and chemotherapy resistance in CRC patients. CONCLUSIONS CAFs secreted exosomes promote metastasis and chemotherapy resistance of CRC. Inhibiting exosomal miR-92a-3p provides an alternative modality for the prediction and treatment of metastasis and chemotherapy resistance in CRC.

Abstract
Objective: The serotype screening of Shigella flexneri from 1934 to 1965 preserved by the National Center for Medical Culture Collections was carried out, and the molecular characteristics of the serotype conversion strains were studied. Methods: Serotyping of Shigella flexneri in this study was conducted by slide agglutination and multiplex PCR, respectively. The gtrⅡ gene sequence alignment and pulsed field gel electrophoresis typing were performed on the serotype conversion strains. Results: Among the 255 strains of Shigella flexneri preserved in CMCC (B) from 1934 to 1965, 79 were carrying gtrⅡ gene, of which 19 strains and 1 strain were agglutinated with the Y serotype and X serotype, respectively, and furthermore, the multiplex PCR assays results showed serotypes 2a and 2b, respectively, and the strains were considered to have serotype conversion. The 20 strains carrying the gtrⅡ gene showed multiple nucleotide mutations. Besides 3 strains of 3 amino acid mutations, the amino acid sequences of the other 17 strains showed a stop codon in advance, resulting in functional inactivation of gtrⅡ. PFGE analysis revealed that the similarity between the serotype Y strain carrying the gtrⅡ gene and the serotype 2a strain was 75.8%-100%, and the similarity between the serotype X strain carrying the gtrⅡ gene and the serotype 2b strain was 81.6%-100%. Conclusion: Mutations in the gtrⅡ gene are more complicated in serotype-transforming Shigella flexneri serotype Y or X strains. Molecular typing suggests that the serotype-transforming Shigella flexneri serotype Y or X strains may be derived from the Shigella flexneri serotype 2a or 2b, and advance the serotype conversion to 1949.

Abstract
BACKGROUND Vitiligo is a common depigmentation disorder resulting from destruction of melanocytes, and has both genetic and environmental influences. Although genomic analyses have been performed to investigate the pathogenesis of vitiligo, the lipidomics, metabolomics and proteomics of serum have not been reported, and the role of small molecules and serum proteins in vitiligo remains unknown. AIM To study the metabolite and protein profiles in patients with vitiligo and healthy controls (HCs). METHODS Plasma samples from 60 participants (29 patients with vitiligo and 31 HCs) were analysed. Untargeted lipidomics, metabolomics and isobaric tags for relative and absolute quantification-based proteomics were performed using high performance liquid chromatography-tandem mass spectrometry. In addition, to validate differentially expressed metabolites in patients with vitiligo, plasma enzyme-linked immunosorbent assay was performed. RESULTS We identified differential expression of several metabolites and proteins involved in the immune system. Among these metabolites and proteins, lysophosphatidylcholine, platelet-activating factor, sn-glycerol-3-phosphocholine, succinic acid, CXCL4 and CXCL7 were significantly elevated in the plasma of patients with vitiligo, while aspartate was downregulated. CONCLUSION Our study has characterized several serum metabolites and proteins that could be potential candidate biomarkers in vitiligo, and provides a comprehensive insight into the role of immune system and aspartate metabolism in vitiligo.

Abstract
Objective: To investigate the feasibility and significance of modified Killian(MK) method in the clinical diagnosis of congenital pyriform sinus fistula(CPSF) by electronic laryngoscopy. Methods: The following examinations were performed for 30 suspected cases of CPSF, including the traditional electronic laryngoscopy, MK examination(modified Killian position+ head rotation+ the Valsalva maneuver), barium swallow X-ray(BSX) and CT , and a prospective comparison among them were done. Patients were divided into two groups according to their age: young age group(≤14 years old) and older age group (>14 years old). The results of MK examination from the patients were analyzed and the positive diagnostic rates (PDR) between groups were compared by using χ(2) tests. Results: Sinuses in 20 of 30 patients were depicted from pyriform sinus in BSX, and the PDR was 66.7%(20/30). The PRD of CT was 83.3%(25/30). The presence of air bubbles around the upper lobe of the thyroid gland or at the inferomedial edge of cricothyroid joints, morphological changes of thyroid grand as well as pseudo-fistula formation on lower neck were detected clearly on CT. Comparing to the traditional electronic laryngoscopy, the effect of exposing piriform fossa fistula by MK examination is significant(χ(2)=17.05, P<0.05), with the PDR of 13.3%(4/30) and 76.7%(23/30) respectively. Nevertheless, comparing to BSX and CT, there were no statistically significant differences in the effect to diagnose CPSF (χ(2)=0.31, χ(2)=0.10 respectively, P>0.05). The PDR of MK in older group is significantly higher than younger group(χ(2)=6.68, P<0.05). Conclusions: MK examination can clearly reveal the hypopharyngeal anatomical structure and detect the sinus of CPSF .It could be a safe, feasible, convenient and economical method as an application in preoperative diagnosis and follow-up examination of clinical suspected CPSF.

Abstract
Objective To investigate the characteristics and associated factors of invasive fungal disease in patients with systemic lupus erythematosus from Southern China. Methods A retrospective study was performed. Demographic and clinical characteristics, laboratory data, and radiographic manifestations were recorded. Results A total of 45 lupus patients with invasive fungal disease (incidence 1.1%) were included. Twenty-three cases (51.1%) were infected with mold and 22 cases (48.9%) with yeast. Aspergillus spp. (44.4%) and Cryptococcus spp. (33.3%) were common. Aspergillosis mainly occurred in the lung. Cryptococcosis developed in the lung (40.0%), meninges (46.7%) and bloodstream (13.3%). Compared with yeast infection, mold infection tended to develop in patients with active lupus nephritis (65.2% vs. 31.8%, P = 0.03) and the mortality rate was higher (20.0% vs. 0%, P = 0.001). Co-infection with bacteria, virus or superficial fungi occurred in 12 patients (26.7%). Multivariate logistic regression analysis indicated that lymphopenia (odds ratio 2.65, 95% confidential interval 1.14–6.20, P = 0.02) and an accumulated dose of glucocorticoid (odds ratio 1.58, 95% confidence interval 1.10–2.25, P = 0.01) was associated with invasive fungal disease in lupus patients. Conclusion Mold infection tended to develop in patients with active lupus disease with high mortality. Co-infection is not rare. Lymphopenia and an accumulated dose of glucocorticoid are associated with invasive fungal disease in lupus patients.
