Abstract
BACKGROUND MiR-150-5p is one of the miRNAs in the expression profile of miRNAs, and in many previous studies, it has been shown that miR-150-5p may play an important role in peripheral blood dendritic cells (DCs) of allergic rhinitis (AR) patients. We sought to investigate the role and mechanism of miR-150-5p in regulating DC function by modulating EGR2 and influencing T cell derivation to promote AR development. METHODS The expression of miR-150-5p and EGR2 in AR patients was examined by real-time quantitative polymerase chain reaction (qRT-PCR), the expression of IL-4 cytokines in the supernatant of AR patients was tested by enzyme-linked immunosorbent assay (ELISA), and the expression of eosinophils in the supernatant of AR patients was measured by HE staining. The expression of EGR2 was detected by immunohistochemistry and fluorescent m-immunohistochemistry. RESULTS MiR-150-5p expression was up-regulated and EGR2 expression was down-regulated in peripheral blood DCs from AR patients. miR-150-5p upregulated DCs, which promoted T-cell differentiation. miR-150-5p further regulated EGR2, which suppressed DCs and caused alteration of T-cell differentiation, in turn triggering the occurrence of AR. CONCLUSION MiR-150-5p and its target gene EGR2 are involved in the development of AR, and DCs foster T-cell differentiation in peripheral blood of AR patients.

Abstract
Objective: To explore the non-bacterial pathogen distribution, epidemiological characteristics, and clinical features of acute respiratory infections in children in Sichuan Province. Methods: Using a retrospective cohort study method, this study selected hospitalized children diagnosed with acute respiratory infections at West China Second Hospital of Sichuan University from February 2019 to January 2021, and tested 13 pathogens using polymerase chain reaction (PCR)-fragment analysis. The children were divided into infant group (<1 year old), toddler group (1 year old ≤ age <3 years old), preschool group (3 years old ≤ age <6 years old) and school-age group (6 years old ≤ age <18 years old). The distribution of pathogen positive rates, seasonal epidemic characteristics, clinical characteristics, and some laboratory test indicators were analyzed in children. Statistical analysis was performed on the results using SPSS 22.0 software, with count data expressed as percentages and inter group comparisons using SPSS 22.0 software χ2 Inspection. Results: A total of 2 922 pediatric patients were included in this study, with 1 748 (59.8%) positive for pathogens detected. Among them, 1 391 (79.6%) were detected as a single pathogen, and 357 (20.4%) were detected as a mixture of two or more pathogens. The most commonly detected pathogens were rhinovirus (HRV) (39.7%), syncytial virus (RSV) (22.8%), and parainfluenza virus (PIV) (12.5%). Pathogen positivity is more common in children under 6 years old (χ2=146.59, P<0.001), with a slightly higher positivity rate in male children (61.3%, 1 047/1 707) than in female children (57.7%, 701/1 215) (χ2=3.91, P=0.048), and compared with pathogen negative children, positive children are more prone to symptoms such as cough, wheezing, and shortness of breath (χ2=259.15, 366.06, 12.48, P<0.001). The distribution of different pathogens varies among children of different age groups, and HRV is more common in children aged 1-3 and 3-6 years old (χ2=9.74, P<0.001), while RSV is more common in children under 1 year old (χ2=178.63, P<0.001), while mycoplasma pneumoniae (MP) and influenza virus (InfA/B) are less common in children under 1 year old (χ2=92.54, 12.90,22.21, P<0.01). The prevalence of multiple pathogens showed seasonal changes. HRV showed a high prevalence trend in spring and autumn, while the prevalence of RSV infection was mainly seen in autumn and winter festivals. The positive rate of different pathogens after the outbreak of novel coronavirus pneumonia was significantly lower than that before the outbreak (χ2=252.68, P<0.001). Conclusion: The detection rate of non-bacterial respiratory pathogens in children in Sichuan Province from 2019 to 2021 is high, which is prone to symptoms such as cough, wheezing, and shortness of breath, with HRV and RSV being the main types. The positive rate of respiratory pathogens varies among different age groups, genders, and seasons.

Abstract
BACKGROUND Cuproptosis is a new type of programmed cell death involved in the regulation of neuroendocrine tumors, immune microenvironment, and substance metabolism. However, the role of cuproptosis-related genes (CRGs) in Hepatocellular carcinoma (HCC) remains unclear. METHOD Through multiple bioinformatics analysis, we constructed a prognostic gene model and competing endogenous RNA (ceRNA) network. The correlation between CRGs and prognosis, immune infiltration, immune checkpoints, microsatellite instability (MSI) and tumor mutational burden (TMB) was analyzed by Kaplan-Meier curve, univariate Cox, multivariate regression, and Spearman's analysis in HCC patients. Besides, the qRT-PCR and immunohistochemistry assays were used to determine prognostic CRGs mRNA and protein expression in HCC. RESULTS We established a novel 3-gene signature related to CRGs for evaluating the prognosis of HCC patients. HCC patients with high risk scores had a poor prognosis with an area under the curve of 0.737, 0.646, and 0.634 on 1-year, 3-year, and 5-year receiver operating characteristic curves. Significant correlation was observed between prognostic CRGs and immune infiltration, immune checkpoints, MSI and TMB. We also developed five ceRNA networks to regulate the occurrence and progression of HCC. CDKN2A, DLAT, and PDHA1 protein expression was up-regulated in HCC versus normal tissues. Besides, the mRNA expression levels of CDKN2A, DLAT, GLS, and PDHA1 were elevated in the HCC cell lines compared to the normal liver cell lines. CONCLUSIONS This novel prognostic CRGs signature could be accurately predict the prognosis of patients with HCC. The ceRNA regulatory network might be potential prognostic biomarkers and therapeutic targets for HCC patients.

Abstract
OBJECTIVES This systematic review was conducted to estimate the respective prevalence of gonorrhea among two high-risk populations in China and determine the epidemiological features of gonorrhea in them. STUDY DESIGN Systematic review. METHODS PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang databases were searched to identify studies published between January 1, 1990, and October 31, 2022, with gonorrhea prevalence tested by polymerase chain reaction among female sex workers (FSWs) and men who have sex with men (MSM). Meta-regression and subgroup analyses were used to investigate potential factors of heterogeneity across studies. Trend analysis of prevalence was conducted by the Jonckheere-Terpstra method. RESULTS We identified 88 prevalence data points from 49 studies in China, with 30,853 participants of FSWs and 5523 participants of MSM. Pooled prevalence of gonorrhea among FSWs and MSM were 6.9% (95% confidence interval: 4.6-9.7%) and 2.5% (95% confidence interval: 1.5-3.7%), respectively. The subgroup analyses showed there were period, regional, and specimen collection methods diversities among FSWs, and diversities of the regions and specimen collection anatomical sites were found among MSM, in which the prevalence of rectum and pharynx was significantly higher than the urethra. A decreasing trend in the prevalence of gonorrhea was seen among FSWs (z = -4.03) from 1999 to 2021, not found for MSM in China. CONCLUSION The prevalence of gonorrhea is high in two high-risk groups in China, with extragenital infections requiring particular attention. The findings of this study will provide evidence to formulate national policy and guidance for gonorrhea prevention and control.

Abstract
BACKGROUND Previous studies have revealed the significant roles of SHC SH2 domain-binding protein 1 (SHCBP1) in occurrence and progression of cancers, but there is no pan-cancer analysis of SHCBP1. METHODS In this study, we explored the potential carcinogenic role of SHCBP1 across 33 tumors from the TCGA and GTEx databases. We investigated SHCBP1 expression, prognosis, genetic alterations, tumor mutational burden (TMB) score, microsatellite instability (MSI) and tumor microenvironment from TIMER2, GEPIA2, UALCAN and cBioPortal databases. Moreover, the cellular functions and potential mechanisms were evaluated by GO and KEGG analysis. Besides, the mRNA expression of SHCBP1 was examined using qRT-PCR assay in gastrointestinal cancers. RESULTS SHCBP1 was significantly upregulated in various cancers, and apparent relationship existed between SHCBP1 and survival prognosis in patients. The TMB, MSI, and tumor microenvironment analysis indicated that SHCBP1 was closely related to immune checkpoints, immune targets, as well as CD4+ naive T cell, CD8+ T cell, and neutrophil. Moreover, the cellular functions of SHCBP1 were mainly in regulating cell cycle motor protein activity. In addition, we validated that SHCBP1 mRNA expression was over-expressed in gastrointestinal cancers. CONCLUSIONS This study was the first to systematically determine the prognostic value of SHCBP1, providing a forward-looking perspective on immunotherapy and cellular processes in pan-cancer.

Abstract
β decay of proton-rich nuclei plays an important role in exploring isospin mixing. The β decay of ^{26}P at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in ^{26}Si are unambiguously identified through β-delayed two-proton emission (β2p). Angular correlations of two protons emitted from ^{26}Si excited states populated by ^{26}P β decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the ^{26}Si IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in β-decay experiments.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a major human health concern. Increasing evidence has demonstrated that ubiquitin ligase E4B (UBE4B) may be involved in the occurrence and development of various human cancers and may affect prognosis. However, the specific role and mechanism of UBE4B in HCC is unclear. METHODS A pan-cancer analysis of UBE4B expression, clinicopathological features, and prognosis was performed using bioinformatics techniques. Subsequently, the expression, prognosis, and correlation of UBE4B and its upstream miRNAs and lncRNAs were analyzed. We investigated the relationship between UBE4B expression and immune cell infiltration, immunomodulatory factors, and chemokines in HCC. The expression levels of UBE4B and its upstream lncRNAs (FGD5-AS1, LINC00858, and SNHG16) and miRNAs (hsa-miR-22-3p) were evaluated in HCC cell lines using qRT-PCR. RESULTS UBE4B expression increased in HCC and was correlated with a poor survival rate in patients with HCC. A ceRNA network was established to identify the UBE4B-hsa-miR-22-3p-FGD5-AS1/LINC00858/SNHG16 regulatory axis in HCC. UBE4B expression was significantly associated with immune cell infiltration, immunomodulators, chemokines, and their receptors in HCC. The mRNA expression of FGD5-AS1, LINC00858, SNHG16, and UBE4B was higher in the HCC cell lines (7721 and HepG2) than in the normal hepatocyte line (LO2), and the expression of hsa-miR-22-3p mRNA showed a decreasing trend. CONCLUSIONS Our findings showed that upregulation of UBE4B was associated with poor prognosis and tumor immune infiltration in HCC. These findings will aid in understanding the relevant functions of UBE4B and provide new strategies for drug development and exploration of prognosis-related biomarkers.

Abstract
Background Hepatocellular carcinoma (HCC) is a major public health problem in humans. The imbalance of mitochondrial function has been discovered to be closely related to the development of cancer recently. However, the role of mitochondrial-related genes in HCC remains unclear. Methods The RNA-sequencing profiles and patient information of 365 samples were derived from the Cancer Genome Atlas (TCGA) dataset. The mitochondria-related prognostic model was established by univariate Cox regression analysis and LASSO Cox regression analysis. We further determined the differences in immunity and drug sensitivity between low- and high-risk groups. Validation data were obtained from the International Cancer Genome Consortium (ICGC) dataset of patients with HCC. The protein and mRNA expression of six mitochondria-related genes in tissues and cell lines was verified by immunohistochemistry and qRT-PCR. Results The six mitochondria-related gene signature was constructed for better prognosis forecasting and immunity, based on which patients were divided into high-risk and low-risk groups. The ROC curve, nomogram, and calibration curve exhibited admirable clinical predictive performance of the model. The risk score was associated with clinicopathological characteristics and proved to be an independent prognostic factor in patients with HCC. The above results were verified in the ICGC validation cohort. Compared with normal tissues and cell lines, the protein and mRNA expression of six mitochondria-related genes was upregulated in HCC tissues and cell lines. Conclusion The signature could be an independent factor that supervises the immunotherapy response of HCC patients and possess vital guidance value for clinical diagnosis and treatment.

Abstract
Background Anillin (ANLN) is an actin-binding protein that is essential for cell division and contributes to cell growth and migration. Although previous studies have shown that ANLN is related to carcinogenesis, no pan-cancer analyses of ANLN have been reported. Accordingly, in this study, we evaluated the carcinogenic roles of ANLN in various cancer types using online databases. Methods We evaluated the potential carcinogenic roles of ANLN using TIMER2 and Gene Expression Omnibus databases with 33 types of cancers. We further investigated the associations of ANLN with patient prognosis, genetic alterations, phosphorylation levels, and immune infiltration in multiple cancers using GEPIA2, cBioPortal, UACLAN, and TIMER2 databases. Additionally, the potential functions of ANLN were explored using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. Reverse transcription quantitative polymerase chain reaction and immunohistochemistry were used to determine ANLN mRNA and protein expression in colorectal cancer (CRC), gastric cancer (GC), and hepatocellular carcinoma (HCC) cell lines. Results ANLN was overexpressed in various tumor tissues compared with corresponding normal tissues, and significant correlations between ANLN expression and patient prognosis, genetic alterations, phosphorylation levels, and immune infiltration were noted. Moreover, enrichment analysis suggested that ANLN functionally affected endocytosis, regulation of actin cytoskeleton, and oxytocin signaling pathways. Importantly, ANLN mRNA and protein expression levels were upregulated in gastrointestinal cancers, including CRC, GC, and HCC. Conclusions Our findings suggested that ANLN participated in tumorigenesis and cancer progression and may have applications as a promising biomarker of immune infiltration and prognosis in various cancers.

Abstract
OBJECTIVES To collect single piece of dandruff with microscopes to improve the regular EZ-tape method for DNA extraction and genotyping, increase the utilization of samples, reduce the miss rate as well as the proportion of genotyping results of mixed stains. METHODS The insides of the hats worn by two volunteers were stuck by EZ-tape and scotch tape respectively. DNA on EZ-tape was directly extracted using traditional method. Single piece of dandruff was collected from the scotch tapes under microscope. The two kinds of methods were both performed under continuous oscillation and standing digestion, respectively. DNA was extracted through Chelex-100 method, and STR genotypes were obtained after amplification and electrophoresis. The results of STR genotypes obtained by EZ-tape method and single piece of dandruff analytical method were compared. RESULTS Miss detections happened in 11 samples (45.8%) by EZ-tape method and only single-source typing results were obtained. Ten samples (41.7%) showed the genotype results of mixed stain and six of which showed allele insertions and deletions. The genotype results were obtained successfully using the single piece of dandruff analytical method, and two samples showed mixed stain genotype. The number of exact typing processed by oscillation was higher than that by standing digestion ( P<0.05). CONCLUSIONS The oscillation during the DNA extraction process is in favour of the DNA releasing. Single piece of dandruff analytical method can be used to obtain single-source STR genotype with high successful ratio and low miss rate. This method can be a collection method of special samples such as dandruff in forensic practice.

Abstract
AIMS Whether lung adenocarcinoma subtype has influence on lymph node involvement in small-sized lung cancer is still unclear. If it has, we want to clarify the extent of the impact. METHODS We identified 2268 operable lung adenocarcinoma patients with tumor size ≤ 3 cm who had undergone a lobectomy and systematic nodal dissection at Shanghai Chest Hospital between July 2012 and December 2014. The histologic subtypes of all patients were classified according to the IALSC/ATS/ERS classification. The relationship between lymph node involvement and clinicopathologic characteristics was evaluated. RESULTS Lymph node involvement (pN1+ pN2) was found in 7 of 220 (3.2%) patients with tumor size ≤ 1.0 cm, 173 of 1196 (14.5%) patients with tumor size >1.0, ≤2.0 cm, and 265 of 852 (31.1%) patients with tumor size > 2.0, ≤3.0 cm. Among all 2268 patients, the percentages of lymph node involvement (pN1+ pN2) were: 47.6%, 47.2%, 24.0%, 18.9%, 18.1%, 0%, 0%, and 0% for solid predominant (Sol), micropapillary predominant (MIP), variants of invasive adenocarcinoma (VIA), papillary predominant (Pap), acinar predominant (Aci), lepidic predominant (Lep), minimally invasive adenocarcinoma (MIA), adenocarcinoma in situ (AIS), respectively. For Sol and MIP, the percentages of lymph node involvement were significantly higher than other subtypes, 50.0% and 66.7% in tumor size ≤ 1.0 cm, 42.0% and 38.6% in tumor size > 1.0, ≤2.0 cm, 52.2% and 55.7% in tumor size > 2.0, ≤3.0 cm. CONCLUSION Our study revealed that lung adenocarcinoma subtypes had important role in lymph node involvement for the patients with small-sized lung cancer.

Abstract
Achieving a very strong magnetic anisotropy in a 3d material is a difficult, but not an impossible task. It is difficult because there is no general recipe (necessary condition) for a strong anisotropy in a band magnet. Several strategies can be pursued in this situation. One of them is to re-examine the less studied 3d compounds, somewhat neglected since the discovery of the Nd-Fe-B magnets 30 years ago. As an example, a single crystal of (Fe0.7Co0.3)2B has been investigated in this work.

Abstract
BACKGROUND To establish and validate the scale of quality of life( QOL) fit for Chinese lung cancer patients. METHODS By reviewing the other scales of QOL, we designed the new scale of QOL which include 5 factors with totally 65 items. It referred to biological and psychosocial aspects. Three hundred fifty-five patients with lung cancer were reviewed. The scores were compared with KPS by different group mean t-test. RESULTS Patients and doctors could understand the contents of this scale, except for 2 patients who only accepted elementary education. Significant differencewas observed in total score, gender and emotional well-being among patients in different stage( P < 0. 05) . The functional well-being of stage IV patients was worse than that of other stage patients( P < 0. 05) . The emotional well-being of female patients was worse than that of male patients( P < 0. 05) . CONCLUSIONS This scale is reliable, valid and capable in clinics.

Abstract
Phenothiazine radical cation PTH(+*) and phenothiazine dication PTH(2+) produced by photoinduced electron transfer in phenothiazine/semiconductor systems have been studied by using ESR, UV-visible absorption, and fluorescence spectroscopic methods. It is found that the PTH(+*) was generated by electron transfer from (1)PTH* and (3)PTH* to the conduction band of the semiconductors besides PTH(+*) resulted in the photoionization of PTH as well as PTH(2+) produced by electron transfer from PTH(+*) to the conduction band of the semiconductors successively. Very significant supplementary information provided by UV-visible absorption, ESR, and resonance Raman spectra of PTH(+*) and PTH(2+), which were obtained by oxidation of PTH with lead tetraacetate, not only confirmed the two-step mono-electron-transfer mechanism proposed for interpretation of electron-transfer processes in PTH/semiconductor systems but also demonstrated that the two successive electron-transfer steps were corresponding to the removal of a p-electron at the nitrogen atom and a p-electron at the sulfur atom in the PTH molecule, respectively. Consequently, the nonplanar configuration of the PTH molecule changed into a planar configuration of the PTH(2+). Copyright 2000 Academic Press.

Abstract
BACKGROUND To compare the response and survival time of autologous peripheral blood stem cell assisted high-dose chemotherapy with conventional chemotherapy in treatment of small cell lung cancer (SCLC) and to access treatment-related toxicities of high-dose chemotherapy. METHODS Twenty-seven patients with SCLC at age <= 65 yrs entered this study. Thirteen patients were given at high dose of cyclophosphamide (CTX,3. 0 g/ m(2) ) , etoposide (VP16 ,750 mg/ m(2) ) , carboplatin (CBP ,400 mg/ m(2) ) and cisplatin (DDP ,60 mg/ m(2) ) with autologous peripheral blood stem cell support by G-CSF (300mug/ d for 5 or 6 days) after one to three cycles of conventional chemotherapy with ifosfamide + vindesine + DDP ( IVP regimen) or ifosfamide + VP16 + DDP ( IEP regimen) or CTX+ VP16 + DDP (CEP regimen) . Forteen patients were given two courses of conventional chemotherapy with IVP or CEP or VP16 + DDP(EP regimen) . Patients in stage II and stage IIIA were given irradiation or surgical recection after chemotherapy and others by chemotherapy continuously. RESULTS Response rate to conventional chemotherapy was 78. 6 % after one cycle and 85. 7 % after two cycles respectively , and that to high-dose chemotherapy was 100 %. The difference was not statistically significant ( P > 0. 05) . The survival time was 58 to 569 days for high-dose chemotherapy and 90 to 430 days for conventional chemotherapy respectively , and Log Rank test showed P < 0. 001. The main toxicity of high-dose chemotherapy was bone marrow suppression and all patients occured grade IV leukopenia and 61. 5 % occured grade IV thrombocytopenia , but they recovered in half month after stem cell transplantation and nobody died from high-dose chemotherapy. CONCLUSIONS High-dose chemotherapy with support of autologous peripheral blood stem cell is an effective therapy for SCLC. Patients has higher response and longer survival time and less toxicity.

Abstract
Twelve canine left lung allotransplantation were performed. In the ischemic preconditioning group (Group IP, n = 6), left donor lung was preconditioned with 10 min ischemia followed by 15 min reperfusion using the occuluding left hilum before resection and cold perfusion. The control group (Group C, n = 6) underwent the same treatment but without ischemic preconditioning. Adenine nucleotides (ATP, ADP, AMP) of the donor lung tissue were measured using rHPLC after 2 hr of resection and cold perfusion with Euro-Collins solution (ECS). The results showed that contents of ATP and total adenine nucleotides (TAN) were much higher in Group IP than in Group C (322.9 +/- 61.2, 942.9 +/- 134.5 and 200.0 +/- 50.0, 668.4 +/- 59.6 mumol.g-1 respectively, P < 0.05). Histologic examination of the donor lung in Group IP showed less damage than in Group C after 2 hr of transplantation. The results suggest that IP combined with cold ECS perfusion can reduce the energy metabolism in canine donor lung.

Abstract
Thermal motions in supercoiled DNA are studied by Brownian dynamics (BD) simulations with a focus on the site juxtaposition process. It had been shown in the last decade that the BD approach is capable of describing actual times of large-scale DNA motion. The bead model of DNA used here accounts for bending and torsional elasticity as well as the electrostatic repulsion among DNA segments. The hydrodynamic interaction among the beads of the model chain and the aqueous solution is incorporated through the Rotne-Prager tensor. All simulations were performed for the sodium ion concentration of 0.01 M. We first showed, to test our BD procedure, that the same distributions of equilibrium conformational properties are obtained as by Monte Carlo simulations for the corresponding DNA model. The BD simulations also predict with accuracy published experimental values of the diffusion coefficients of supercoiled DNA. To describe the rate of conformational changes, we also calculated the autocorrelation functions for the writhe and radius of gyration for the supercoiled molecules. The rate of site juxtaposition was then studied for DNA molecules up to 3000 bp in length. We find that site juxtaposition is a very slow process: although accelerated by a factor of more than 100 by DNA supercoiling, the times of juxtaposition are in the range of ms even for highly supercoiled DNA, about two orders of magnitude higher than the relaxation times of writhe and the radius of gyration for the same molecules. By inspecting successive simulated conformations of supercoiled DNA, we conclude that slithering of opposing segments of the interwound superhelix is not an efficient mechanism to accomplish site juxtaposition, at least for conditions of low salt concentration. Instead, transient distortions of the interwound superhelix, followed by continuous reshaping of the molecule, contribute more significantly to site juxtaposition kinetics.

Abstract
The aim of this study was to assess whether spectral turbulence analysis (STA) of the signal-averaged electrocardiogram (SAECG) is of prognostic use in patients with idiopathic dilated cardiomyopathy. SAECGs were recorded at presentation in 84 patients with idiopathic dilated cardiomyopathy and STA was performed using 183 Del Mar software. STA was abnormal (> or = 3 of the 4 standard parameters beyond the normal range) in 31 patients (37%). Patients were followed for a mean duration of 24 +/- 18 months (range 1 to 59) during which time 24 (29%) developed progressive heart failure (14 underwent cardiac transplantation), 4 died suddenly or had aborted sudden death, and the others remained clinically stable. Progressive heart failure occurred more often in patients who had an abnormal versus a normal STA result (15 [48%] vs 9 [17%]; p < 0.002). Actuarial survival revealed a 1-year survival of 90% in patients with a normal STA result, and 63% in patients with an abnormal STA result (p < 0.01). The predictive ability of STA to identify patients with progressive heart failure was sensitivity 63%, specificity 77%, positive predictive value 54%, and negative predictive value 83%. Univariate analysis identified peak oxygen consumption as having the largest relative risk for the development of progressive heart failure (9.55, 95% confidence interval [CI] 2.1 to 43.9). Left ventricular end-diastolic dimension (relative risk 4.18, 95% CI 1.5 to 11.4) and STA (relative risk 3.81, 95% CI 1.7 to 8.8) were also significantly associated with the development of progressive heart failure.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two groups of Paragonimus westermani (Tematoda: Platyhelminthes) exist in nature: diploids and triploids. Generally, these two groups live allopatrically, but in Kuandian, Liaoning Province, in the Republic of China, they live sympatrically. In our Chinese experiment on Paragonimus we used metacercariae of P. westermani, which we collected in Kuandian, Xigutai, and performed a cytological analysis. The results were as follows: (1) the P. westermani in Xigutai lived sympatrically as diploids and triploids; (2) all of the small metacercariae were diploids; (3) the large metacercariae were in large proportion triploids; (4) we found one tetraploid specimen in both the medium and the large metacercariae--this was the first time tetraploid lung flukes were discovered; (5) the somatic chromosomes of the tetraploids were different in numbers (4n = 44), but we could not find any difference in the karyotype of haploid sets and that of the diploids and the triploids; (6) unlike the triploids, during their meiosis the tetraploids produced a chromosome pairing, and we found a tendency of the large chromosomes to become quadrivalent; and (7) also unlike the triploids, a great number of spermatids were found in the tetraploid testes. Because of these findings, we can consider tetraploids to be autotetraploids, and these are probably produced by the fertilization of diploids and triploids. We also think that the gametes of tetraploids have a fertilization capability.
