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
Selenium (i.e., Se) is a trace element that is vital in poultry nutrition, and optimal forms and levels of Se are critical for poultry productivity and health. This study aimed to compare the effects of sodium selenite (SS), yeast selenium (SY), and methionine selenium (SM) at selenium levels of 0.15 mg/kg and 0.30 mg/kg on production performance, egg quality, egg selenium content, antioxidant capacity, immunity and selenoprotein expression in laying hens. The trial was conducted in a 3 × 2 factorial arrangement, and a total of 576 forty-three-wk-old Hyland Brown laying hens were randomly assigned into 6 treatment groups, with diets supplemented with 0.15 mg Se/kg and 0.3 mg Se/kg of SS, SY and SM for 8 wk, respectively. Results revealed that SM increased the laying rate compared to SS and SY (P < 0.05), whereas different selenium levels had no effect. Organic selenium improved egg quality, preservation performance, and selenium deposition compared to SS (P < 0.05), while SY and SM had different preferences for Se deposition in the yolk and albumen. Also, organic selenium enhanced the antioxidant capacity and immune functions of laying hens at 0.15 mg Se/kg, whereas no obvious improvement was observed at 0.30 mg Se/kg. Moreover, SY and SM increased the mRNA expression of most selenoproteins compared to SS (P < 0.05), with SM exhibiting a more pronounced effect. Correlation analysis revealed a strong positive association between glutathione peroxidase 2 (GPx2), thioredoxin reductases (TrxRs), selenoprotein K (SelK), selenoprotein S (SelS), and antioxidant and immune properties. In conclusion, the use of low-dose organic selenium is recommended as a more effective alternative to inorganic selenium, and a dosage of 0.15 mg Se/kg from SM is recommended based on the trail conditions.

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
The study aimed to investigate whether linoleic acid could improve the intestinal barrier function of squabs under weaning stress conditions. Totally 320 7-day-old weaned squabs were randomly divided into 4 treatment groups, including control group (CON), 0.7% linoleic acid addition group (LA007), 1.4% linoleic acid addition group (LA014) and 2.1% linoleic acid addition group (LA021). At 21d, 8 squabs were randomly selected from each treatment group for sampling and determination. The results showed that adding linoleic acid could improve (P < 0.05) the body weight of weaned squabs, and LA014 had the best effect. With the increase of linoleic acid dosage, villi height and villi area increased linearly or quadratically (P < 0.05), and reached the maximum in LA021 or LA014, respectively. The linoleic acid supplementation could improve the intestinal tight junction of weaned squabs, and the LA014 was the most significant (P < 0.05). With the linoleic acid increasing, the levels of intestinal IL-6 and TNF-αdecreased linearly (P < 0.05), while intestinal IL-10 increased quadratically (P < 0.05) and reached the maximum in LA014. Serum endotoxin and diamine oxidase levels decreased linearly (P < 0.05) and reached the lowest level in LA014. The ultrastructure of villi revealed that the length of ileal microvilli in LA014 was significantly increased (P < 0.05) and the microvilli became dense, and the mitochondria in epithelial cells returned to normal state. Further exploring the mechanism of linoleic acid alleviating intestinal injury caused by weaning stress in squabs, it was found that linoleic acid down-regulated (P < 0.05) the relative protein expression of TLR4, MyD88, phosphorylated JNK and phosphorylated p38, reducing secretion of pro-inflammatory factors IL-6 and TNF-α. This study indicate that linoleic acid could alleviate intestinal barrier injury of early weaned squabs by down-regulating TLR4-MyD88-JNK/p38-IL6/TNF-α pathway.

Abstract
Appreciation of the importance of Akkermansia muciniphila is growing, and it is becoming increasingly relevant to identify preventive and/or therapeutic solutions targeting gut-liver-brain axes for multiple diseases via Akkermansia muciniphila. In recent years, Akkermansia muciniphila and its components such as outer membrane proteins and extracellular vesicles have been known to ameliorate host metabolic health and intestinal homeostasis. However, the impacts of Akkermansia muciniphila on host health and disease are complex, as both potentially beneficial and adverse effects are mediated by Akkermansia muciniphila and its derivatives, and in some cases, these effects are dependent upon the host physiology microenvironment and the forms, genotypes, and strain sources of Akkermansia muciniphila. Therefore, this review aims to summarize the current knowledge of how Akkermansia muciniphila interacts with the host and influences host metabolic homeostasis and disease progression. Details of Akkermansia muciniphila will be discussed including its biological and genetic characteristics; biological functions including anti-obesity, anti-diabetes, anti-metabolic-syndrome, anti-inflammation, anti-aging, anti-neurodegenerative disease, and anti-cancer therapy functions; and strategies to elevate its abundance. Key events will be referred to in some specific disease states, and this knowledge should facilitate the identification of Akkermansia muciniphila-based probiotic therapy targeting multiple diseases via gut-liver-brain axes.

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
Early weaning stress has been reported to impair intestinal health in mammals. Like mammals, weaning of the pigeon squab, an altricial bird, is associated with social, environmental and dietary stress. However, understanding of weaning stress on intestinal functions is very limited in altricial birds, especially in squabs. This study was aimed to evaluate the effects of early weaning stress on intestinal microbiota diversity, architecture, permeability, the first line defense mechanisms, mucosal barrier functions, and immune cell responses. A total of 192 newly hatched squabs were randomly allocated into two groups, one weaned on day 7 and the other remained with the parent pigeons. Mucosal tissue and digesta in ileum, as well as blood samples, were collected from squabs (n = 8) on days 1, 4, 7, 10, and 14 postweaning. Our results showed that weaning stress induced immediate and long-term deleterious effects on both growth performance and intestinal barrier functions of squabs. Early weaning significantly increased ileal bacterial diversity and alters the relative abundance of several bacteria taxa. Weaning stress can also cause morphological and functional changes in ileum, including an atrophy in villi, an increase in permeability, and a variation in the mRNA expression of genes encoding mucins, immunoglobulins, tight junction proteins, toll-like receptors, and cytokines, as well as the concentration of secretory IgA. We concluded that the impaired intestinal barrier functions accompanied with early weaning stress seems to be the main reason for the poor growth rate after weaning in squabs. In addition, the disturbance of intestinal microbiota of early weaning stress in squabs coincided with dysfunction of intestinal mucosal barrier and activation of inflammation cell responses that were possibly mediated via the activation of toll-like receptors.

Amino Acid and Fatty Acid Metabolism Disorders Trigger Oxidative Stress and Inflammatory Response in Excessive Dietary Valine-Induced NAFLD of Laying Hens. Front Nutr 2022; 9:849767.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a chronic and metabolic liver disease and commonly occurs in humans with obesity and type 2 diabetes mellitus (T2DM); such a condition also exists in animals such as rodents and laying hens. Since the pathogenesis of fatty liver hemorrhagic syndrome (FLHS) of laying hens is similar to human NAFLD, hen's FLHS is commonly selected as a study model of NAFLD. Altered circulating amino acids, particularly elevated branched-chain amino acids (BCAAs) and aromatic amino acids (AAAs), are consistently reported in patients with NAFLD and T2DM. How long-term dietary individual BCAA, such as valine, impacts amino acid and fatty acid metabolism remains unknown. In this study, we demonstrated that when laying hens are fed with dietary valine at different levels (59, 0.64, 0.69, 0.74, and 0.79%) in a feeding trial that lasted for 8 weeks, long-term exposure to excessive valine diets at 0.74 and 0.79% levels could induce amino acid imbalance, impair amino acid metabolism, increase fatty acid synthesis, and inhibit fatty acid utilization. Long-term intake of excessive dietary valine could result in impaired amino acid metabolism via inhibiting C/EBP-β/asparagine synthetase (Asns). This process is mediated by downregulating the general control nonderepressible-eukaryotic initiation factor 2α- activating transcription factor (GCN2-eIF2α-ATF4) pathway and elevating corresponding circulating BCAAs and AAAs levels, which could ultimately result in amino acid imbalance. High levels of dietary valine stimulated lipid deposition by suppressing the GCN2-eIF2α-ATF4-fibroblast growth factor-19 (FGF19)-target of rapamycin complex 1 (TORC1) signaling pathway to promote fatty acid synthesis, repress fatty acid utilization, and eventually accelerate the development of NAFLD. The Spearman correlation analysis revealed that circulating amino acid imbalance is significantly associated with fatty acid metabolism disorder and enhanced oxidative stress. The inhibition of the GCN2-TORC1 pathway induced autophagy suppression to trigger liver oxidative stress and inflammatory response. In conclusion, our results revealed the adverse metabolic response to excessive dietary valine mediated by amino acid and fatty acid metabolism disorders. This study also suggested reducing dietary valine as a novel approach to preventing and treating NAFLD in humans and FLHS in laying hens.

Abstract
The study was aimed to evaluate the morphology and immune function development of the jejunum and ileum in squab pigeons (Columba livia), by determining the villus ultrastructure, secretory IgA, and cytokines. Eight squabs were randomly selected and sampled on the day of hatch (DOH), d 7 (D 7), 14 (D 14), and 21 (D 21) post-hatch, respectively. The results showed that under transmission electron microscope, the enterocyte circumference in jejunum and ileum decreased with age. The tight junction involved in enterocyte circumference of jejunal villi plateaued from D 7, whereas that of ileal villi changed irregularly. The microvilli of jejunal and ileal villi was maximum at D 14. Under scanning electron microscope, the villus morphology of jejunum and ileum appeared finger-shaped at DOH. After D 7, the jejunal villi were still finger-shaped whereas the ileal villi were leaflike. The secretory IgA in jejunum was significantly increased at D 21. The TGF-β decreased linearly in jejunum and ileum. The anti-inflammatory cytokines increased linearly and proinflammatory cytokines decreased linearly in jejunum and ileum with age. In conclusion, the morphological changes of jejunal epithelium were concentrated at DOH-D 7 and ileal epithelium at DOH-D 14 mainly. The changes in mucus layer and immune-related factors of jejunum and ileum persisted for almost the entire period.

Abstract
The present study aimed to assess the impact of dietary valine levels on layer production performance, egg quality, immunity, and intestinal amino acid absorption of laying hens during the peak lay period. For this purpose, a total of 960 33-week-old Fengda No.1 laying hens were randomly divided into five experimental groups and fed with valine at the following different levels in a feeding trial that lasted 8 weeks: 0.59, 0.64, 0.69, 0.74, and 0.79%, respectively. Productive performances were recorded throughout the whole rearing cycle and the egg quality, serum indexes, and small intestine transporters expression were assessed at the end of the experiment after slaughter (41 weeks) on 12 hens per group. Statistical analysis was conducted by one-way ANOVA followed by LSD multiple comparison tests with SPSS 20.0 (SPSS, Chicago, IL, USA). The linear and quadratic effects were tested by SPSS 20.0. Egg mass, laying rate, broken egg rate, and feed conversion ratio were significantly improved with increasing dietary valine levels. However, the egg weight, eggshell thickness, albumen height, Haugh unit, and egg yolk color were significantly decreased with increasing dietary valine levels. Serum catalase (CAT), immunoglobulin A (IgA) and IgM levels, and malondialdehyde (MDA) levels were negative responses to valine-treated laying hens. Dietary supplemented valine enhanced the trypsin activity of duodenum chime and promoted the mRNA expression levels of ATB0,+, and LAT4 in the jejunum and corresponding serum free Ile, Lys, Phe, Val, and Tyr level. However, valine treatment significantly downregulated the mRNA expression levels of PePT1, B0AT1, LAT1, and SNAT2 in the small intestines and corresponding serum free Arg, His, Met, Thr, Ala, Asp, Glu, Gly, and Ser level. Our results suggest that 0.79% valine dietary supplementation can improve production performance by promoting amino acid nutrient uptake and utilization, and suggest a supplement of 0.79% valine to diet.

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.
