Abstract
Objective: To assess the clinicopathological features, immunophenotype, molecular characteristics and differential diagnosis of primary cardiac synovial sarcoma (PCSS). Methods: Five cases of PCSS were collected at Guangdong Provincial People's Hospital from 2008 to 2023, and their clinicopathological features were summarized. Immunohistochemical staining, fluorescence in-situ hybridization (FISH) and next-generation sequencing (NGS) were performed, and relevant literatures were reviewed. Results: The cases were found in four males and one female, ranging in ages from 16 to 51 years (median 30 years). Two cases were located in the pericardium, two in the right ventricle, and one in the left ventricle. Follow-up data were available in four cases. All the four patients died of disease at 3, 7, 13 and 26 months, respectively, after diagnosis. The tumor maximum diameter ranged from 6.0 to 14.0 cm in (mean 10.0 cm). Microscopically, three cases were monophasic and two cases were biphasic. Immunohistochemically, all cases were immunoreactive for EMA, vimentin, bcl-2 and CD56. The tumor cells were variably positive for pan-cytokeratin, SS18-SSX, SOX2, TLE1, CD99, synaptophysin, calretinin and calponin. FISH showed the presence of SS18 rearrangement in all the cases. NGS detected SS18-SSX gene fusion in three cases (SS18-SSX1 in one and SS18-SSX2 in two). Conclusions: PCSS is an exceedingly rare neoplasm, and should be distinguished from other various malignant epithelial and mesenchymal tumors. The clinical history, histopathological and immunohistochemical features, and molecular findings are all essential to the definitive diagnosis of PCSS.

Abstract
OBJECTIVE Adequate sleep is closely related to people's health. However, with increasing age, the quality of sleep worsens. At the same time, among elderly individuals, frailty is also a disturbing factor, which makes elderly individuals more vulnerable to negative factors. To explore the relationship between the two, we conducted this study. METHODS In this paper, independent genetic variations related to insomnia, sleep duration and daytime sleepiness were selected as IVs, and related genetic tools were used to search published genome-wide association studies for a two-sample Mendelian randomization (TSMR) analysis. The inverse-variance weighted (IVW) method was used as the main Mendelian randomization analysis method. Cochran's Q test was used to test heterogeneity, MR‒Egger was used to test horizontal pleiotropy, and the MR-PRESSO test was used to remove outliers. RESULTS According to our research, insomnia (OR = 1.10, 95% CI 1.03-1.17, P = 2.59e-97), long sleep duration (OR = 0.66, 95% CI 0.37-1.17, P = 0.02), short sleep duration (OR = 1.30, 95% CI 1.22-1.38, P = 2.23e-17) and daytime sleepiness (OR = 1.49, 95% CI 1.25-1.77, P = 0.96e-4) had a bidirectional causal relationship with frailty. CONCLUSIONS Our research showed that there is a causal relationship between sleep disturbances and frailty. This result was obtained by a TSMR analysis, which involves the use of genetic variation as an IV to determine causal relationships between exposure and outcome. Future TSMR studies should include a larger sample for analysis.

Abstract
The interaction between human serum albumin (HSA) and hispidin, a polyketide abundantly present in both edible and therapeutic mushrooms, was explored through multispectral methods, hydrophobic probe assays, location competition trials, and molecular docking simulations. The results of fluorescence quenching analysis showed that hispidin quenched the fluorescence of HSA by binding to it via a static mechanism. The binding of hispidin and HSA was validated further by synchronous fluorescence, three-dimensional fluorescence, and UV/vis spectroscopy analysis. The apparent binding constant (Ka) at different temperatures, the binding site number (n), the quenching constants (Ksv), the dimolecular quenching rate constants (Kq), and the thermodynamic parameters (∆G, ∆H, and ∆S) were calculated. Among these parameters, ∆H and ∆S were determined to be 98.75 kJ/mol and 426.29 J/(mol·K), respectively, both exhibiting positive values. This observation suggested a predominant contribution of hydrophobic forces in the interaction between hispidin and HSA. By employing detergents (SDS and urea) and hydrophobic probes (ANS), it became feasible to quantify alterations in Ka and surface hydrophobicity, respectively. These measurements confirmed the pivotal role of hydrophobic forces in steering the interaction between hispidin and HSA. Site competition experiments showed that there was an interaction between hispidin and HSA molecules at site I, which situates the IIA domains of HSA, which was further confirmed by the molecular docking simulation.

Abstract
BACKGROUND AND AIMS The older people bears a severe burden of disease due to frailty and depressive symptoms, however, the results of association between the two in the older Chinese people have been conflicting. Therefore, this study aimed to investigate the developmental trajectories and interactions of frailty and depressive symptoms in the Chinese middle-aged and older adults. METHODS The study used four waves of data from 2011, 2013, 2015 and 2018 in the China Health and Retirement Longitudinal Study (CHARLS) database, focused on middle-aged and older people ≥ 45 years of age, and analyzed using latent growth models and cross-lagged models. RESULTS The parallel latent growth model showed that the initial level of depressive symptoms had a significant positive predictive effect on the initial level of frailty. The rate of change in depressive symptoms significantly positively predicted the rate of change in frailty. The initial level of frailty had a significant positive predictive effect on the initial level of depressive symptoms, but a significant negative predictive effect on the rate of change in depressive symptoms. The rate of change in frailty had a significant positive predictive effect on the rate of change in depressive symptoms. The results of the cross-lagged analysis indicated a bidirectional causal association between frailty and depressive symptoms in the total sample population. Results for the total sample population grouped by age and gender were consistent with the total sample. CONCLUSIONS This study recommends advancing the age of concern for frailty and depressive symptoms to middle-aged adults. Both men and women need early screening and intervention for frailty and depressive symptoms to promote healthy aging.

Abstract
Trace amine-associated receptor 1 (TAAR1) senses a spectrum of endogenous amine-containing metabolites (EAMs) to mediate diverse psychological functions and is useful for schizophrenia treatment without the side effects of catalepsy. Here, we systematically profiled the signaling properties of TAAR1 activation and present nine structures of TAAR1-Gs/Gq in complex with EAMs, clinical drugs, and synthetic compounds. These structures not only revealed the primary amine recognition pocket (PARP) harboring the conserved acidic D3.32 for conserved amine recognition and "twin" toggle switch for receptor activation but also elucidated that targeting specific residues in the second binding pocket (SBP) allowed modulation of signaling preference. In addition to traditional drug-induced Gs signaling, Gq activation by EAM or synthetic compounds is beneficial to schizophrenia treatment. Our results provided a structural and signaling framework for molecular recognition by TAAR1, which afforded structural templates and signal clues for TAAR1-targeted candidate compounds design.

Abstract
AIMS AND OBJECTIVES To describe dyadic psycho-social intervention measures and to evaluate their influence on stroke survivors and caregiver's functional independence, quality of life, depression, anxiety, self-efficacy and coping ability. BACKGROUND Because of the importance of dyadic intervention and the seriousness of the psycho-social problems of stroke survivors and caregivers, understanding the influence of dyadic psycho-social interventions is vital. DESIGN A systematic review and meta-analysis based on PRISMA guidelines. DATA SOURCES Nine databases were systematically searched for randomized controlled trials submitted from 1910 to 4 July 2022. METHODS The included papers were evaluated for quality, and quantitative data were standardly extracted and analysed by meta-analysis, followed by synthesis. The meta-analysis was carried out using Review Manager 5.4 software. RESULTS Fifteen randomized controlled trials were included (n = 2190 for patients, and n = 1933 for caregivers). Study results showed that dyadic psycho-social interventions significantly alleviated the depressive symptoms of patients, obviously improved the ability to function independently of patients and more quickly alleviated the care burden of caregivers. CONCLUSIONS This study provided moderate support for the benefits of dyadic psycho-social intervention in improving survivor and caregiver's functional independence, quality of life, depression, anxiety, self-efficacy and care burden. Nevertheless, due to limitations of the study, it was deemed necessary that this topic is studied further. RELEVANCE TO CLINICAL PRACTICE This review suggests that dyadic psycho-social interventions should be considered as effective strategies for decreasing psycho-social problems of stroke survivors and caregivers, and provides evidence for the formulation of targeted intervention programs. The personalized implementation of such interventions should be the focus of clinical practice. NO PATIENT OR PUBLIC CONTRIBUTION There was no patient or public contribution.

Abstract
Sex cord tumor with annular tubules (SCTATs) is a rare sex cord stromal tumor in the ovary. SCTAT combined with adult granulosa cell tumor (AGCT) is even rarer. Here, we report a unique case of ovarian tumors with mixed AGCT and SCTAT components. Due to the unusual coexistence, molecular testing was separately performed on each ovary. Both SCTAT and AGCT components were found to have STK11 germline mutation. Furthermore, the AGCT component had an additional FOXL2 somatic mutation. Based on medical history and molecular testing we conclude that the ovarian tumors were associated with Peutz-Jeghers syndrome (PJS). Thus, we present the first report of bilateral PJS-associated SCTAT combined with unilateral AGCT.

Abstract
BACKGROUND The catenin beta 1 gene (CTNNB1) plays a crucial role in the malignant progression of various cancers. Recent studies have suggested that CTNNB1 hyperactivation is closely related to the occurrence and development of bladder cancer (BCa). As a member of the deubiquitinating enzyme (DUB) family, ubiquitin C-terminal hydrolase L3 (UCHL3) is abnormally expressed in various cancers. In this study, we discovered that UCHL3 is a novel oncogene in bladder cancer, suggesting it is a promising target against bladder cancer. METHODS We utilized CRISPR‒Cas9 technology to construct cell lines with UCHL3 stably overexpressed or knocked out. The successful overexpression or knockout of UCHL3 was determined using Western blotting. Then, we performed CCK-8, colony formation, soft agar and Transwell migration assays to determine the impact of the UCHL3 gene on cell phenotype. RNA-seq was performed with UCHL3-depleted T24 cells (established via CRISPR-Cas9-mediated genomic editing). We analyzed differences in WNT pathway gene expression in wild-type and UCHL3-deficient T24 cell lines using a heatmap and by gene set enrichment analysis (GSEA). Then, we validated the effect of UCHL3 on the Wnt pathway using a dual fluorescence reporter. We then analyzed the underlying mechanisms involved using Western blots, co-IP, and immunofluorescence results. We also conducted nude mouse tumor formation experiments. Moreover, conditional UCHL3-knockout mice and bladder cancer model mice were established for research. RESULTS We found that the overexpression of UCHL3 boosted bladder cancer cell proliferation, invasion and migration, while the depletion of UCHL3 in bladder cancer cells delayed tumor tumorigenesis in vitro and in vivo. UCHL3 was highly associated with the Wnt signaling pathway and triggered the activation of the Wnt signaling pathway, which showed that its functions depend on its deubiquitination activity. Notably, Uchl3-deficient mice were less susceptible to bladder tumorigenesis. Additionally, UCHL3 was highly expressed in bladder cancer cells and associated with indicators of advanced clinicopathology. CONCLUSION In summary, we found that UCHL3 is amplified in bladder cancer and functions as a tumor promoter that enhances proliferation and migration of tumor cells in vitro and bladder tumorigenesis and progression in vivo. Furthermore, we revealed that UCHL3 stabilizes CTNNB1 expression, resulting in the activation of the oncogenic Wnt signaling pathway. Therefore, our findings strongly suggest that UCHL3 is a promising therapeutic target for bladder cancer.

Abstract
Since its first application in 2016, spatial transcriptomics has become a rapidly evolving technology in recent years. Spatial transcriptomics enables transcriptomic data to be acquired from intact tissue sections and provides spatial distribution information and remedies the disadvantage of single-cell RNA sequencing (scRNA-seq), whose data lack spatially resolved information. Presently, spatial transcriptomics has been widely applied to various tissue types, especially for the study of tumor heterogeneity. In this review, we provide a summary of the research progress in utilizing spatial transcriptomics to investigate tumor heterogeneity and the microenvironment with a focus on solid tumors. We summarize the research breakthroughs in various fields and perspectives due to the application of spatial transcriptomics, including cell clustering and interaction, cellular metabolism, gene expression, immune cell programs and combination with other techniques. As a combination of multiple transcriptomics, single-cell multiomics shows its superiority and validity in single-cell analysis. We also discuss the application prospect of single-cell multiomics, and we believe that with the progress of data integration from various transcriptomics, a multilayered subcellular landscape will be revealed.

Abstract
The gastrointestinal microbiota, a complex ecosystem, is involved in the physiological activities of hosts and the development of diseases. Birds occupy a critical ecological niche in the ecosystem, performing a variety of ecological functions and possessing a complex gut microbiota composition. However, the gut microbiota of wild and captive birds has received less attention in the same region. We profiled the fecal gut microbiome of wild wintering whooper swans (Cygnus Cygnus; Cyg group, n = 25), captive black swans (Cygnus Atratus; Atr group, n = 20), and mute swans (Cygnus Olor; Olor group, n = 30) using 16S rRNA gene sequencing to reveal differences in the gut microbial ecology. The results revealed that the three species of swans differed significantly in terms of the alpha and beta diversity of their gut microbiota, as measured by ACE, Chao1, Simpson and Shannon indices, principal coordinates analysis (PCoA) and non-metricmulti-dimensional scaling (NMDS) respectively. Based on the results of the linear discriminant analysis effect size (LEfSe) and random forest analysis, we found that there were substantial differences in the relative abundance of Gottschalkia, Trichococcus, Enterococcus, and Kurthia among the three groups. Furthermore, an advantageous pattern of interactions between microorganisms was shown by the association network analysis. Among these, Gottschalkia had the higher area under curve (AUC), which was 0.939 (CI = 0.879-0.999), indicating that it might be used as a biomarker to distinguish between wild and captive black swans. Additionally, PICRUSt2 predictions indicated significant differences in gut microbiota functions between wild and captive trumpeter swans, with the gut microbiota functions of Cyg group focusing on carbohydrate metabolism, membrane transport, cofactor, and vitamin metabolism pathways, the Atr group on lipid metabolism, and the Olor group on cell motility, amino acid metabolism, and replication and repair pathways. These findings showed that the gut microbiota of wild and captive swans differed, which is beneficial to understand the gut microecology of swans and to improve regional wildlife conservation strategies.

Abstract
Recently, there have been growing concerns over the integration of recombinant adeno-associated virus (rAAV) used in gene therapy. Wild-type adeno-associated virus (AAV) site specifically integrates into AAVS1 site of human genome, while rAAV randomly integrates into host chromosomes at low frequencies. This research aims to study the random integration events of rAAV6-EGFP packaged in Sf9 insect cells. Baculo-Sf9 manufacturing platform has the advantages of high-density suspension culture of Sf9 insect cells and large-scale production of rAAV vectors. In this study, we used different doses of Baculo-Sf9 produced rAAV6-EGFP to transduce HEK293T cells and A549-implanted tumors in vitro and in vivo. Using flow cytometry and fluorescence microscopy, we studied their EGFP gene expression efficiencies and EGFP fluorescence intensities. Using inverse nested PCR and DNA sequencing, random integration sites of rAAV6-EGFP genome into human chromosomes were identified. In vitro results showed that gene expression efficiencies became stable after 20 days and random integration frequencies were 0.2-4.2%. Both in vitro and in vivo results indicated that random integration of Baculo-Sf9 rAAV6 was dose-dependent. Sequencing results showed two random integration sites, which were on human chromosomes 8 and 12. The findings suggest that we should use as low dose of rAAV vector as possible for safe gene therapy.

Abstract
Spatial transcriptomics technologies developed in recent years can provide various information including tissue heterogeneity, which is fundamental in biological and medical research, and have been making significant breakthroughs. Single-cell RNA sequencing (scRNA-seq) cannot provide spatial information, while spatial transcriptomics technologies allow gene expression information to be obtained from intact tissue sections in the original physiological context at a spatial resolution. Various biological insights can be generated into tissue architecture and further the elucidation of the interaction between cells and the microenvironment. Thus, we can gain a general understanding of histogenesis processes and disease pathogenesis, etc. Furthermore, in silico methods involving the widely distributed R and Python packages for data analysis play essential roles in deriving indispensable bioinformation and eliminating technological limitations. In this review, we summarize available technologies of spatial transcriptomics, probe into several applications, discuss the computational strategies and raise future perspectives, highlighting the developmental potential.

Abstract
Objective: To explore the repair methods of complex facial defect wounds involving paranasal sinuses and their clinical effectiveness. Methods: A retrospective observational study was conducted. From January 2020 to May 2022, 5 patients admitted to the Department of Burns and Plastic Surgery of Xiangya Hospital of Central South University and 4 patients admitted to the Department of Burns and Plastic Surgery of Chenzhou First People's Hospital with complex facial defect wounds involving paranasal sinuses met the inclusion criteria, including 6 males and 3 females, aged 35-69 years, including 4 patients with titanium mesh exposure combined with paranasal sinuses injury and 5 patients with tumor involving paranasal sinuses. After an adequate assessment of the damage by a multiple discipline team, titanium mesh removal, paranasal sinus debridement, and paranasal sinus mucosa removal were performed in patients with exposed titanium mesh, and radical tumor resection was performed in patients with tumors, with postoperative skin and soft tissue defects areas of 5.0 cm×2.5 cm to 18.0 cm×7.0 cm, anterior paranasal sinus wall defects/absence areas of 3 cm×2 cm to 6 cm×4 cm, and sinus cavity depths of 1 to 4 cm. Depending on the perforator course of the descending branch of the lateral circumflex femoral artery, the anterolateral femoral chimeric flap or anterolateral femoral myocutaneous flap (with flap area of 9 cm×4 cm to 19 cm×8 cm, muscle size of 5 cm×3 cm×3 cm to 11 cm×6 cm×3 cm) was transplanted to repair the defect, and the donor site wound was sutured directly. The type of tissue flap transplanted, the blood vessel of the recipient area, and the vascular anastomosis way during the operation, the recovery of the donor and recipient areas and the occurrence of complications after operation were observed. The appearance and blood supply of the recipient area and the recurrence of ulcers and tumors were followed up. Results: The anterolateral femoral myocutaneous flap transplantation was performed in 6 patients, and the anterolateral femoral chimeric flap transplantation was performed in 3 patients. The blood vessels in recipient areas were facial arteries and veins in 3 cases and superficial temporal arteries and veins in 6 cases. The superficial temporal arteries and veins were bridged with blood vessels in tissue flaps by flow-through way in 2 patients, and end-to-end anastomosis of blood vessels in donor and recipient areas was performed in 7 patients. After operation, all the tissue flaps survived, and the facial defect wounds were well repaired without cerebrospinal fluid leakage or paranasal sinus secretion leakage, no intracranial infection occurred, and the wounds in donor areas were healed well. Follow-up of 6-35 months after operation showed that all the patients had good blood supply in the recipient area, and the shape was acceptable; 4 patients with exposed titanium mesh had no recurrence of ulceration, and 5 patients with tumor had no local tumor recurrence or metastasis. Conclusions: Based on an adequate assessment of the extent of paranasal sinuses involved in the facial wound and the nature of the defect, good clinical effects can be achieved by using the anterolateral femoral muscle flap or the anterolateral femoral chimeric flap transplantation to repair complex facial defect wounds with open paranasal sinuses.

Abstract
In response to physical, chemical, and/or biological stimuli, considerable tissue self-degradation occurs in abalone, causing severe post-harvest quality loss. During this process, the extracellular matrix (ECM) is greatly degraded by endogenous proteases. The main component of the ECM is collagen, primarily type I collagen. Although the activity of matrix metalloproteinases (MMPs), which can specifically degrade collagen, is precisely regulated by tissue inhibitors of MPs (TIMPs), indicating that MMPs and TIMPs play crucial roles in the regulation of tissue self-degradation, few studies have reported the interaction between MMPs and TIMPs. In this study, we reveal collagenases to participate in postmortem tissue self-degradation of Haliotis discus hannai by degrading type I collagen. The recombinant MMP-1 catalytic domain (rMMP1c) of abalone with high purity and enzyme activity is expressed using a prokaryotic expression system. The optimum temperature and pH for rMMP1c are 37 °C and 7.0, respectively. The thermal denaturation temperature of rMMP1c is 67.0 ± 0.9 °C. Ethylenediamine tetraacetic acid (EDTA) and 1,10-phenanthroline can completely inhibit rMMP1c activity, while Ba2+, Ca2+, and Mg2+ can significantly elevate it. TIMP is also expressed using HEK 293F cells. Recombinant TIMP (rTIMP) shows good inhibitory activity toward rMMP1c. Inhibition kinetics analyses reveal rTIMP to be a competitive inhibitor of rMMP1c. Biolayer interferometry reveals that rTIMP can effectively bind with rMMP1c, with an equilibrium dissociation constant value of 263 nM. rMMP1c effectively degrades type I collagen γ-β-α chains in turn, and rTIMP can significantly inhibit rMMP1c degradation activity. These results provide a theoretical basis for the study of MMP and TIMP interaction and elucidate the possible mechanism for abalone tissue self-degradation.

Abstract
OBJECTIVE To investigate the diversity and composition of microflora in laboratory-reared Aedes albopictus at different developmental stages and larval habitat waters. METHODS The larval habitat waters and different developmental stages of laboratory-reared A. albopictus were collected, and the V3 and V4 regions of the bacterial 16S rRNA gene were sequenced using Illumina Miseq next-generation sequencing. The abundance and diversity of the microflora were examined using alpha diversity index in A. albopictus at different developmental stages, and the difference in the microflora compositions was compared in A. albopictus at different developmental stages using principal component analysis (PCA). In addition, the species composition and relative abundance of microflora in A. albopictus at different developmental stages were described using histograms and Venn diagrams. RESULTS A total of 16 phyla, 30 classes, 72 orders, 129 families and 224 genera of bacteria were detected in larval habitat waters and different developmental stages of A. albopictus. The highest bacterial diversity was seen in larval A. albopictus, with Chao index of 125.20 ± 30.48 and Shannon diversity index of 2.04 ± 0.39, which were comparable to those (Chao index of 118.52 ± 15.07 and Shannon diversity index of 2.15 ± 0.30) in larval habitat waters (t = 0.35 and -0.41, both P values > 0.05). The bacterial abundance and evenness were significantly greater in female adults than in male adults (Chao index: 42.50 ± 3.54 vs. 18.50 ± 2.13, t = 8.23, P < 0.05; Shannon diversity index: 1.25 ± 1.67 vs. 0.50 ± 0.05, t = 6.00, P < 0.05). Proteobacteria, Bacteroidota, Actinobacteriota and Finnicutes were four common phyla of bacteria at each developmental stage of A. albopictus, with Proteobacteria dominated at the pupal stage (90.36%), Bacteroidota dominated at the adult stage (46.01% in female adults and 86.11% in male adults), and Actinobacteriota dominated at the larval stage (32.10%). Elizabethkingia and Rahnella 1 were common dominant genera of bacteria at each developmental stage of A. albopictus, with Rahnellal as the major component at the pupal stage (87.56%), Elizabethkingia as the main component at the adult stage (46.01% in female adults and 86.11% in male adults, respectively), and Microbacteria as the dominant bacterial genus at the larval stage (12.11%). In addition, Delftia, Elizabethkingia, Romboutsia, Serratia, Rahnella 1, Enterococcus and Microbacterium were common genera of bacteria at each developmental stage of A. albopictus, with Edaphobaculum dominated at the larval stage (17.54%) and Sphingobacterium dominated in larval habitat waters (13.93%). CONCLUSIONS There are differences in the composition of symbiotic bacteria at different developmental stages of A. albopictus; however, similar microflora diversity is maintained at the phylum level. The microflora diversity is comparable in larvae and larval habitat waters of A. albopictus.

Abstract
Objective: To explore the clinical characterist ics and risk factors of hemorrhage complicated by hemoperfusion therapy in patients with acute poisoning. Methods: In January 2021, the clinical data of 196 patients with acute poisoning who received hemoperfusion therapy in the Second Affiliated Hospital of Air Force Military Medical University from January 2018 to December 2020 were analyzed, and the patients were divided into bleeding group and non-bleeding group according to whether the patients were complicated with bleeding. Multivariate logistic regression was used to analyze the independent risk factors for hemorrhage in patients treated with hemoperfusion. Results: A total of 21 patients in the bleeding group and 175 patients in the non-bleeding group were included. There was no significant difference in general data such as gender, age, and body mass index between the two groups (P>0.05) . Organophosphorus pesticides (χ(2)= 4.56, P=0.030) , HA230 perfusion device (χ(2)=4.12, P=0.042) , platelet count (t=-2.33, P=0.009) and activated partial thromboplastin time (t=14.53, P<0.001) at 2 h of perfusion were the influencing factors of hemorrhage in patients with acute poisoning treated with hemoperfusion. Among them, organophosphorus pesticides, 2 h perfusion activated partial thromboplastin time ≥35 s and other factors were independent risk factors forcomplicated bleeding (P<0.05) . Conclusion: Patients with acute poisoning, especially organophosphorus pesticide poisoning, are at greater risk of bleeding during hemoperfusion therapy. Monitoring of changes in activated partial thromboplastin time should be strengthened and the dose of anticoagulants should be adjusted in time to reduce the risk of bleeding.

Abstract
An artificial light-harvesting system with two-step sequential energy transfer was constructed in aqueous media based on cyano-substituted p-phenylenevinylene derivative (PPTA) and bis-(p-sulfonatocalix[4]arenes) (BSC4) supramolecular polymers formed through host-guest interactions, in which two different fluorescent dyes, eosin Y (EY) and sulforhodamine (SR101), were employed as energy acceptors. The obtained artificial light-harvesting system can achieve an efficient two-step energy transfer process from PPTA-BSC4 to EY and then to SR101 with high energy-transfer efficiencies of up to 36.6% and 40.8%, respectively. More importantly, the harvested energy from the PPTA-BSC4 + EY + SR101 system can be used to promote the dehalogenation of α-bromoacetophenone with a yield of 89% in aqueous solution.

Abstract
OBJECTIVE To investigate the distribution and density of Culex mosquito populations and the resistance of Culex pipiens pallens to insecticides in Jiangsu Province in 2018 and 2019. METHODS During the period from June to October in 2018 and 2019, six counties (districts, cities) were sampled in southern, northern and central Jiangsu Province as surveillance sites. The density of Culex mosquitoes was measured overnight using the light trapping technique. In addition, Culex pipiens pallens mosquitoes were collected from Hai'an of Nantong City and Yandu District of Yancheng City, central Jiangsu Province, and the sensitivity of female first filial generations to dichlorodiphenyltrichloroethane (DDT), malation, proposur, beta cypermethrin and deltamethrin was tested using the standard WHO insecticide susceptibility test assay. RESULTS A total of 104 423 Culex mosquitoes were captured in six surveillance sites of Jiangsu Province in 2018 and 2019, and Culex quinquefasciatus (49.11%), Culex pipiens pallens (28.38%), and Culex tritaeniorhynchus (21.04%) were predominant species. The density of Culex mosquitoes started to increase since early June, peaked in July and tended to be low in late October. Culex pipiens pallens mosquitoes captured from Hai'an was susceptible to malation, while those from Yandu District were moderately resistant to malation. Culex pipiens pallens mosquitoes from both Yandu and Hai'an were moderately resistant to proposur, and were resistant to DDT, beta cypermethrin and deltamethrin. CONCLUSIONS Culex quinquefasciatus, Culex pipiens pallens and Culex tritaeniorhynchus are predominant Culex species in Jiangsu Province. Culex pipiens pallens is resistant to DT, beta cypermethrin and deltamethrin in central Jiangsu Province.

Abstract
OBJECTIVE To analyze the changes of small molecular metabolites in the larvae of a deltamethrin-sensitive strain of Anopheles sinensis following exposure to deltamethrin, so as to provide the scientific basis for investigating the metabolic pathway and screening metabolic markers of deltamethrin in An. sinensis. METHODS The 50% and 75% lethal concentrations (LC50 and LC75) of deltamethrin against the larvae of a deltamethrin-sensitive strain of An. sinensis were calculated in laboratory. The type and content of An. sinensis larvae metabolites were detected using high performance liquid chromatography and mass spectrometry (LC-MS/MS) following exposure to deltamethrin at LC50 and LC75 for 30 min and 24 h, and the changes of metabolites were analyzed. RESULTS The LC50 and LC75 values of deltamethrin were 4.36 × 10-3 µg/mL and 1.12 × 10-2 µg/mL against thelarvae of a deltamethrin-sensitive strain of An. sinensis. Following exposure of the larvae of a deltamethrin-sensitive strain of An. sinensis to deltamethrin at LC50 and LC75 for 30 min, the differential metabolites mainly included organic oxygen compounds, carboxylic acid and its derivatives, fatty acyl and pyrimidine nucleotides, with reduced glucose levels. Following exposure for 24 h, the differential metabolites mainly included organic oxygen compounds, carboxylic acid and its derivatives, aliphatic acyl and purine nucleotides, with increased glucose level detected. CONCLUSIONS Carbohydrate, carboxylic acid and its derivatives, fatty acyls, amino acids and their derivatives may play important roles in deltamethrin metabolism in the larvae of a deltamethrin-sensitive strain of An. sinensis.

Abstract
Objective: To explore the repair methods and clinical effects of full-thickness burn wounds deep to tendon or even bone in fingers. Methods: A retrospective non-randomized controlled trial was conducted on the 98 patients with full-thickness finger burns deep to tendon or even bone who met the inclusion criteria and were hospitalized in Xiangya Hospital of Central South University from January 2010 to December 2019. Among the 98 patients, there were 81 males and 17 females, aged from 1 to 72 years, with 160 fingers involved. The wound area of each of affected fingers ranged from 2.0 cm×1.5 cm to 12.0 cm×3.5 cm, and the maximum wound area after merging the affected fingers was 12.0 cm×10.0 cm. For adult hands with multiple full-thickness burn wounds deep to tendon or even bone in multiple fingers or children with full-thickness finger burns deep to tendon or even bone, pedicled abdominal flaps were selected. For adults with single or two fingers with full-thickness burns deep to tendon or even bone, the pedicled internal hand flaps and free tissue flaps were selected. The free tissue flap repair requires good vascular conditions in the recipient area with arteries and veins available for anastomosis. For thumb nail burns deep to tendon or even bone or partial absence of the thumb after burns, the thumbs were reconstructed with the first toenail flap or dorsal foot flap with the second toe. In this study, 45 pedicled abdominal flaps were used to repair the wounds in 91 fingers, 37 pedicled internal hand flaps were used to repair the wounds in 37 fingers, 26 free tissue flaps were used to repair the wounds in 28 fingers, 3 first toenail flaps were used to reconstruct 3 patients' thumb nails and to repair hand wounds, and 1 dorsal foot flap with the second toe was used to reconstruct 1 patient's thumb and to repair hand and wrist wounds. The tissue flap area was from 2.0 cm×1.5 cm to 20.0 cm×10.0 cm. The wound in the donor site was repaired by direct suture or full-thickness skin grafting from the medial upper arm of the affected limb or split-thickness skin grafting from the outer thigh. The postoperative survival of the tissue flap, postoperative complications, and appearance and function of the flap donor site were observed. For the patients who were followed up, their finger functions were evaluated at the last follow-up using the trial criteria for replantation function evaluation of the amputated finger issued by the Hand Surgery Society of the Chinese Medical Association, and the satisfaction of the patients was investigated using the Efficacy Satisfaction Scale. Data were statistically analyzed with Kruskal-Wallis H test and Nemenyi test. Results: Of the 112 tissue flaps, 104 tissue flaps survived completely and had good blood circulation; 1 pedicled thumb dorsal ulnar reverse island flap, 1 pedicled finger artery cutaneous branch reverse island flap, and 1 free grafted anterolateral thigh perforator flap were slightly necrotic at the end, which were repaired with outer thigh split-thickness skin graft after dressing change and granulation tissue growth; 2 free grafted tarsal external artery flaps and 1 pedicled thumb dorsal ulnar reverse island flap suffered from postoperative venous return obstruction, which survived after partial suture removal and heparin saline cleansing of the wound; 1 pedicled modified dorsal metacarpal artery retrograde island flap and 1 free grafted peroneal artery perforator flap were necrotic, which were repaired by a pedicled abdominal flap and a lateral upper arm flap free transplantation respectively in stage Ⅱ. After transplantation, the tissue flaps had good shape, soft texture, and good elasticity, without bloating. There was no functional disorder in the flap donor site, and only slight scar remained. A total of 117 fingers of the 72 patients received 3-24 months of outpatient or telephone follow-up. At the last follow-up, the excellent and good rates of function evaluation of fingers repaired with pedicled abdominal flap, pedicled internal hand flap, and free tissue flap were respectively 77.3% (51/66), 96.3% (26/27), and 95.8% (23/24). The function of fingers repaired with free tissue flap and pedicled internal hand flap was significantly better than that with pedicled abdominal flap (P<0.01). The satisfaction of patients with fingers repaired by free tissue flaps was significantly higher than that by pedicled abdominal flap (P<0.05). Conclusions: According to the specific situation of full-thickness burn wounds deep to tendon or even bone in fingers, the pedicled abdominal flap is used to repair the multiple full-thickness burn wounds deep to tendon or even bone in multiple fingers of adult or the full-thickness burn wounds deep to tendon or even bone in fingers of children, the pedicled internal hand flap or free tissue flap is used to repair the full-thickness burn wounds deep to tendon or even bone in single or two fingers of adult patients, and the first toenail flap or the dorsal foot flap with the second toe is used to reconstruct the thumbs with full-thickness burn deep to tendon or even bone, with high postoperative tissue flap survival rate and few complications. The functional recovery of the affected finger is better after repair with free tissue flap and pedicled internal hand flap, and the patients' satisfaction is the highest after free tissue flap repair.

Abstract
Objective: To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy. Methods: A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO's recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics. Results: A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant (P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% (OR=1.42, 95%CI: 1.07-1.88, P=0.015), 46% (OR=1.46, 95%CI: 1.13-1.88, P=0.004), and 64% (OR=1.64, 95%CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study (P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age (OR=2.87, 95%CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 (OR=1.59, 95%CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes (OR=1.58, 95%CI: 1.18-2.13, P=0.002) and premature delivery (OR=1.52, 95%CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM (OR=5.34, 95%CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM (OR=1.44, 95%CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia (OR=4.11, 95%CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia (OR=1.46, 95%CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery (OR=1.47, 95%CI: 1.13-1.92, P=0.004). Conclusions: Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.

Abstract
Objective: To assess the relationship between body mass index (BMI) and death risk of cardiovascular disease (CVD) in rural male population. Methods: 22 282 men aged 40 years older in Tanghe county and Fenghuang county from the cohort of the "Prospective Study on Adult Behavior and Health Risk Factors in China" were selected as subjects of this study. Cox regression model was used to calculate the hazard ratios (HRs) of the death of CVD during the follow-up period with different BMI groups at baseline. Results: The average follow-up period in the two counties was (19.1±8.7) years and 10 828 (48.6%) people died during the follow-up period. 4 504 deaths were attributed to CVD. Among the deaths of CVD, 1 279 cases died of ischemic heart disease (IHD), ischemic stroke (IS) died in 1 201, cases died of died of 1 317 hemorrhagic stroke (HS), other 707 cases. Compared to population with BMI<18 kg/m(2), Cox regression model (adjusting factors of region, age, nationality, education level, occupation, smoking, drinking, blood pressure, blood pressure, etc.) showed that people with BMI between 20-22 kg/m(2) had the lowest risk of CVD death (HR=0.95, 95%CI: 0.83-1.09). But the difference was not statistically significant among each BMI group (P>0.05). The risk of IHD death was the lowest in the population with BMI between 20-22 kg/m(2) (P<0.05) (HR=0.64, 95%CI: 0.52-0.80). There was no statistically significant difference between the risk of IHD death in the population with BMI≥24 kg/m(2) and that in the population with BMI<18 kg/m(2) (P>0.05). There was no statistically significant difference between the risk of IS death and BMI (P>0.05). The death risk of HS in the population with BMI between 18-24 kg/m(2) was higher than that in the population with BMI<18 kg/m(2) (P<0.05). The death risk of the population with BMI between 26-28 kg/m(2) was the highest (HR=1.88, 95%CI:1.18-2.99). Conclusions: The mortality risk of CVD and IHD was the lowest in lean or normal weight group, and HS was higher in overweight group. Maintaining a reasonable weight can reduce the risk of death in patients with CVD.

Abstract
Objective: To explore the clinical effects of simultaneous reconstruction of multiple joint scar contracture deformity of limb. Methods: From January 2010 to June 2018, 24 patients with multiple joint scar contracture deformity of the same limb were reconstructed in simultaneous operations in Xiangya Hospital of Central South University, including 16 males and 8 females, aged 3-42 years, with 15 patients having deformities in the upper limbs and 9 patients having deformities in the lower limbs. One operation was performed to repair contracture deformity of axillary fossa and elbow in 3 patients, cubital fossa and palmar of wrist in 4 patients, cubital fossa and hand in 5 patients, palmar of wrist, palm, and palmar of finger in 3 patients, groin and medial knee in 2 patients, popliteal fossa and posterior ankle in 1 patient, and anterior ankle and dorsum of foot in 6 patients. After the release of various joint scar contractures, the area of skin defect was 140 to 580 cm(2). Autologous full-thickness skin grafts were used in 7 patients, autologous medium-thickness skin grafts were used in 4 patients, autologous full-thickness skin grafts combined with local skin flaps were used in 9 patients, and allogeneic acellular dermal matrix and autologous thin skin grafts were used in 4 patients. Comprehensive measures for rehabilitation were taken and the survival of the skin graft was observed after operation. Six months to eight years after the operation, all the patients were followed up for the functions of the affected limbs, among which the functions of the upper limbs were evaluated according to the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association. The joint mobility, walking, and squatting function of lower extremity were examined after operation. Recurrence of contractures in all the affected limbs and reoperation were recorded. Results: The grafts survived after operation in 22 patients. Two patients had necrosis in small full-thickness skin area, of which one was healed by skin grafting after debridement, and the other one was healed after dressing changes. The deformity of scar contracture at each repaired joint was completely or partially corrected. During a follow-up for 6 to 96 months, the upper limb functions of 15 patients were rated excellent in 12 patients and good in 3 patients. Among the 9 patients of lower limb scar contractures, except for one 3-year-old child who experienced recurrence of medial knee scar contracture and underwent surgical release and skin grafting 5 years later, the remaining 8 patients basically recovered normal joint functions with pretty good outcomes. Conclusions: For continuous scar contracture deformity of multiple joints of the same limb, simultaneous surgical release and skin grafting can reduce operation frequency and obtain better outcomes of surgical operation.

Abstract
1. Birds' newly oviposited blastoderms can survive several weeks in a dormant state during low-temperature storage. Previous studies demonstrated that there is a critical temperature range from 19 to 27°C for chicken embryos. Within this range, the embryo will diapause in a dormant state; once the temperature rises above this range, the blastoderm will break dormancy. 2. Clarifying the mechanism that initiates duck embryo developmental recovery from blastoderm dormancy will be helpful to change temperature control to improve hatching in poultry production. It was hypothesised that there might be some temperature-sensitive genes involved in initiating duck embryo developmental recovery from blastoderm dormancy. 3. To test this hypothesis, the transcriptome of the newly oviposited duck blastoderm and duck embryo (incubated for 48 hours) were sequenced to screen for differentially expressed genes with functions that had been predicted by bioinformatics. 4. The results showed that there were 2416 differentially expressed genes between the two groups, 53 of which were involved in temperature-sensitive pathways. The protein-protein interaction network combined these 53 temperature-sensitive genes and another group of 65 genes, which enriched the development pathway. These results suggested that temperature-sensitive genes may be involved in growth and development related pathways.

Abstract
The Keggin-type polyoxometalates (POMs) are effective catalysts for oxidative desulfurization (ODS) and confining these POMs in metal-organic frameworks (MOFs) is a promising strategy to improve their performances. Herein, postsynthetic modification of POMs confined in MOFs by adding thiourea creates more unsaturated metal sites as defects, promoting ODS catalytic activity. Additional modification by confining 1-butyl-3-methyl imidazolium POMs in MOFs is performed to obtain higher ODS activity, owing to the affinity between electron-rich thiophene-based compounds and electrophilic imidazolium compounds. The ODS catalytic activities of four Zr-MOF-based composites (bottle around ship) including phosphomolybdate acid (PMA)/UiO-66, [Bmim]3 PMo12 O40 /UiO-66, PMA/Thiourea/UiO-66, and [Bmim]3 PMo12 O40 /Thiourea/UiO-66 are therefore investigated in detail. In order to explore the catalytic mechanism of these MOF composites, their microstructures and electronic structures are probed by various techniques such as X-ray diffraction, thermogravimetric analysis, Fourier transform infrared, Raman, scanning electron microscope, transmission electron microscope, BET, X-ray photoelectron spectroscopy, EPR, UV-vis, NMR spectra, and H2 -temperature-programmed reduction. The results reveal that phosphomolybdate blues and imidazolium phosphomolybdate blues with different Mo5+ /Mo6+ ratios with the Keggin structure are confined in defected UiO-66 for all four composites. This approach can be applied to design and synthesize other POMs/MOFs composites as efficient catalysts.

Abstract
Objective: To analyze clinical characteristics and wound repair methods and effects of patients with upper limb electric burns. Methods: Medical records of 136 patients with upper limb electric burn who met the inclusion criteria and hospitalized in our unit from January 2015 to March 2019 were retrospectively analyzed. Proportion in patients with electric burns in the same period, gender, age, admission time, categories, injury causes, injury voltage, burn area and depth of upper limb, simultaneous injury of both upper limbs, and early wound treatment measure of patients with upper limb electric burn were recorded. The main repair methods of each affected limb were classified and recorded. The overall efficacy of the patients was recorded, including postoperative wound complications and healing condition. The patients repaired with distal pedicled flaps and those with free flaps were followed up for 3 to 6 months. The survival rate of flaps were recorded, the function of affected limbs after operation was evaluated, and the satisfaction degree of patients was investigated by Curative Effect Score Table. The amputation rate, age, and burn area of upper limbs of patients caused by high-voltage and low-voltage electricity were compared. Data were processed with Wilcoxon rank sum test, chi-square test, or Fisher's exact probability test. Results: (1) The number of upper limb electric burn patients accounted for 88.3% of 154 patients with electric burns hospitalized in the same period, including 117 males and 19 females, aged 1 year and 2 months to 72 years [(34±18) years], admitted 1 h to 48 d after injury, including 51 electricians, 32 rural migrant workers, 31 students and preschool children, and 22 patients belonging to other categories. Patients of the first two categories were mainly injured by work accidents, and those of the latter two categories mainly suffered from touching power source or power leakage. Among all the patients, 75 cases were injured by high-voltage electric burn, and 61 cases were injured by low-voltage electric burn, with burn area of upper limb from 0.2% to 16.0% [2% (1%, 5%)] total body surface area (TBSA) and area of wounds deep to bone from 0.2% to 15.0% [2% (1%, 5%)] TBSA. Two upper limbs in 54 cases were simultaneously injured, accounting for 39.7%. Early fasciotomy was performed for 73 limbs. (2) Thirteen affected limbs were treated with dressing change, 2 affected limbs were sutured directly after debridement, 56 affected limbs were repaired by skin grafting, 12 affected limbs were repaired by local flap, 45 affected limbs were repaired by distal pedicled flap, 22 affected limbs were repaired by free flap, and 40 affected limbs were amputated (accounting for 21.1%). (3) One case died of pulmonary infection, sepsis, and multiple organ failure after operation, and the rest patients were all cured. One case with avulsion of abdominal flap was repaired by skin grafting after dressing change. The anterolateral thigh flap in one case necrotized after transplantation, which was replaced by pedicled abdominal flap. Seven cases had small erosion on the pedicle or margin after transplantation of abdominal flap and were healed by dressing change. Six cases had local bruising at the distal end after transplantation of abdominal flap and were healed after conservative treatment such as hyperbaric oxygen. The other flaps survived well. (4) The survival rate of distal pedicled flap grafting was 97.8% (44/45), which was close to that of free flap grafting (95.5%, 21/22, P>0.05). The function recovery of affected limb after free flap grafting was better than that of distal pedicled flap grafting (Z=-3.054, P<0.01), but their satisfaction degree of patients was similar (Z=-0.474, P>0.05). (5) Patients with high-voltage electric burn had higher amputation rate, older age, and larger upper limb burn area than those with low-voltage electric burn (χ(2)=4.743, Z=-2.801, -6.469, P<0.05 or P<0.01). Conclusions: Upper extremity electric burn often occurs in children, electricians, and rural migrant workers with high rate of amputation. Teachers and parents should strengthen safety education for children and manage power source of life well. Workers should improve safety awareness and operate standardly. Fasciotomy for relaxation should be performed for electric burn wound as soon as possible, and flap grafting can effectively repair wound after early debridement. The function recovery of affected upper limb repaired with free flap grafting is better.

Abstract
Interrupted time series (ITS) is a statistical method for the quasi-experimental design specific to the outcome of time series, in which the effectiveness of an intervening measure is evaluated by examining change in slope and immediate change in level. The key feature of ITS is that the secular trend of time series prior to the intervention can be effectively controlled so as to accurately estimate the intervention effect. The design principle and statistical method for ITS were illustrated by an example of evaluating halving policy for the expert registration fee in the general hospital of a city. The segmented linear regression was used to fit the above time series data and the results were explained in detail. Meanwhile, the study design and model fitting along with explanations of the results with respect to the effects of two types of successive interventions and on different time-points of an intervention were illustrated as well in this paper. The existed upward or downward trend should be taken into account in order to accurately estimate the intervention effect as it exists in most of the public health surveillance data. Two parameters, known as change in slope and immediate change in level, were employed to evaluate the effect of the intervention. The ITS analysis can be widely applied to the program evaluation as it could enrich methods of the evaluation compared to the traditional model of the program evaluation.

Abstract
The aim of present study was to investigate the effect of different times (5 min (UCPP-5), 10 min (UCPP-10), 20 min (UCPP-20), and 30 min (UCPP-30)) of ultrasound treatment on physicochemical, thermal, and antioxidant properties of chicken plasma protein (CPP). UCPP-20 had the highest fluorescence intensity and the lowest particle size. However, no major changes in the subunit compositions and the secondary structure of UCPPs were presented in SDS-PAGE and circular dichroism. The surface hydrophobicity and sulfhydryl content of UCPPs increased significantly (P < 0.05) as compared to those of CPP. With the increasing time of ultrasound treatment, there were more and deeper holes on the protein surfaces. Furthermore, protein modification by ultrasound could improve the thermal properties of UCPPs. Additionally, UCPPs showed a significant increase in antioxidant properties over CPP, especially UCPP-20. These observations indicated that ultrasound treatment was necessary for modification of CPP to meet the requirements for food processing.

Abstract
Objective: To explore the relationship between genotype and phenotype of ABCB11 deficiency. Methods: Clinical data of two siblings with ABCB11 deficiency were retrospectively analyzed. Related literature from PubMed, CNKI and Wangfang databases was reviewed to date (up to August 2017) with 'ABCB11 gene' or 'bile salt export pump', 'cholestasis' and 'child' as key words. Results: The patients were siblings. Both of them presented as jaundice, pruritus and hepatosplenomegaly since 3 days after birth. Significant laboratory findings on admission of the older sister included high total bilirubin, 170 µmol/L;conjugated bilirubin, 115.8 µmol/L;alanine aminotransferase, 168 U/L;total bile acid 186.3 µmol/L and normal gamma-glutamyl transpeptidase. While routine laboratory data of the younger brother were as follows: total bilirubin, 148.8 µmol/L;conjugated bilirubin, 96.3 µmol/L;alanine aminotransferase, 232.8 U/L;total bile acid 226 µmol/L, and normal gamma-glutamyl transpeptidase.Both received ursodeoxycholic acid and fat-soluble vitamins. Liver pathology of the younger brother showed giant hepatocytes with ballooning degeneration, focal necrosis and intrahepatic cholestasis. Both the patients harbor the same compound heterozygous mutations in ABCB11 gene, c.145C>T (p.Q49X) and c.1510G>A (p.E504K). The sister is 9 years old now, with normal liver function. Jaundice faded around 3 months after birth, pruritus relieved at age 5, and medications was stopped since then. The brother progressed to liver failure after an operation on perianal abscess when he was 8-month-old, and received living-related liver transplantation when he was 9 month and 20 days old (from his mother). Now he is 1 year and 5 months old, with normal liver function. Both are under our follow-up. Literature review revealed 18 ABCB11 deficiency patients from 7 families who had apparent different prognoses, within each family the siblings had the same ABCB11 gene mutation. Seven cases relieved after ursodeoxycholic acid therapy and/or partial external biliary diversion, 5 received orthotopic liver transplantation, 2 developed hepatocellular carcinoma and 4 cases died in childhood. Conclusions: The clinical manifestations of ABCB11 deficiency may vary greatly in patients carrying the same genotype, even in siblings. Patients should be managed in individualized maner.

Abstract
Objective: To explore the clinical value of endoscopic interventional therapy for locally recurrent primary lung adenoid cystic carcinoma (ACC). Methods: The clinical data of 42 patients with locally recurrent ACC were retrospectively analyzed, and the differences of tracheal and bronchial diameter, airway scoring grade and airway obstruction degree before and after treatment were compared among three treatment methods: bronchoscopic interventional therapy + palliative radiotherapy, interventional therapy alone, and non-interventional therapy. Log rank test and Cox proportional risk model multi-factor analysis were used to determine the prognostic factors of ACC patients with local recurrence, and the long-term effect of bronchoscopic interventional therapy on ACC with local recurrence was determined. Results: The median overall survival of 42 patients was 59 months and 5-year survival rate was 54.2%.Univariate analysis showed that vascularized cancer, pleural invasion, pulmonary atelectasis, incisal margin, microscopic classification, tumor diameter, initial TNM stage, ki-67 index, and treatment after local recurrence were associated with long-term survival of ACC patients with local recurrence (all P<0.05). Cox multivariate regression analysis showed that margin status (RR=0.272, P=0.011), tumor diameter (RR=2.586, P=0.005), initial TNM staging (RR=0.369, P=0.035), ki-67 index (RR=3.569, P<0.001), and treatment methods after local recurrence (RR=0.126, P<0.001) were independent factors influencing the prognosis of ACC patients with local recurrence. After three months of treatment, the tracheal bronchus diameters, rating of shortness of breath, and degree of airway obstruction were all improved significantly (all P<0.05), both in the interventional therapy + palliative radiotherapy group [(14.5±2.8 mm, 0.86±0.45, (14.50±10.67)%, respectively], and the interventional therapy alone group [(13.7±2.3) mm, 0.97±0.25, (15.38±12.02)%, respectively]. Meanwhile, the difference before and after non-interventional therapy was not statistically significant (all P>0.05). 5-year overall survival rates were 55.8%, 46.6% and 42.6% for patients undergoing interventional therapy+ palliative radiotherapy, interventional therapy alone, and non-interventional therapy after recurrence, with statistically significant differences (P=0.015). Patients underwent bronchial endoscopic interventional therapy and palliative radiotherapy had the best efficacy of treatment. Conclusion: Endoscopic interventional therapy plus palliative radiotherapy is an effective local palliative treatment for locally recurrent ACC patients, which can rapidly relieve airway stenosis, improve the quality of life of patients and prolong the survival time of patients.

Abstract
This study aimed to explore the feasible effect of ezetimibe for postprandial hyperlipidemia (PPHP).Sixty participants were included in this study. Of these, 30 subjects in the intervention group received ezetimibe, while the remaining 30 participants in the control group did not undergo ezetimibe. All patients in intervention group were treated for a total of 2 weeks. Primary endpoints consisted of serum levels of total cholesterol (Total-C), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG). Secondary endpoints included apoB-48, remnant lipoprotein cholesterol (RLP-C), blood glucose, insulin, hemoglobin A1c (HbA1c), and monocyte chemotactic protein (MCP). All outcomes were measured before and after 2-week treatment.After 2-week treatment, participants in the intervention group did not show better outcomes in primary endpoints of Total-C, LDL-C, HDL-C, and TG; and secondary endpoints of apoB-48, RLP-C, blood glucose, insulin, HbA1c, and MCP, compared with subjects in the control group.The results of this study showed that ezetimibe may be not efficacious for participants with PPHP after 2-week treatment.

Abstract
Objective: To investigate the effect of different negative pressure of wound negative pressure dressing (NPD) on the survival of full-thickness skin grafts of patients. Methods: One hundred and eleven patients who need skin grafting, conforming to the inclusion criteria were hospitalized in our unit from August 2012 to March 2017, and their clinical data were retrospectively analyzed. Forty-seven patients hospitalized from August 2012 to October 2015 were assigned into traditional treatment group. Sixty-four patients hospitalized from November 2015 to March 2017 were divided into -9.975 kPa negative pressure treatment group (n=34) and -13.300 kPa negative pressure treatment group (n=30). Patients in traditional treatment group received conventional dressing after full-thickness skin grafting. Patients in -9.975 kPa and -13.300 kPa negative pressure treatment groups received -9.975 kPa and -13.300 kPa NPD based on traditional treatment after vacuum sealing, respectively. Dot necrosis area of skin grafts and erosion and escharosis of graft edges of patients in the three groups on post operation day 10 were observed. The percentage of dot necrosis area of skin grafts and occurrence rate of erosion and escharosis of skin graft edges were calculated, respectively. Data were processed with chi-square test, Fisher's exact test, and Kruskal-Wallis H test. Results: Percentages of dot necrosis area of skin grafts of patients in traditional treatment group and -9.975 kPa and -13.300 kPa negative pressure treatment groups were 17.81%, 3.20%, and 3.00%, respectively. Percentage of dot necrosis area of skin grafts of patients in traditional treatment group was significantly higher than that in -9.975 kPa and -13.300 kPa negative pressure treatment groups (Z=-5.770, -4.690, P<0.001). Percentages of dot necrosis area of skin grafts of patients in -9.975 kPa and-13.300 kPa groups were close (Z=-0.619, P>0.05). The occurrence rates of erosion and escharosis of skin graft edges of patients in traditional treatment group and -9.975 kPa and -13.300 kPa negative pressure treatment groups were 78.7% (37/47), 32.4 (11/34), and 36.7% (11/30), respectively. Erosion and escharosis of skin graft edges of patients in -9.975 kPa and -13.300 kPa negative pressure treatment groups were better than those in traditional treatment group (P<0.001). Erosion and escharosis of skin graft edges of patients in -9.975 kPa and -13.300 kPa negative pressure treatment groups were close (P>0.05). Conclusions: The use of -9.975 kPa and -13.300 kPa NPD in skin grafts after full-thickness skin grafting significantly diminishes the occurrence rates of dot necrosis area of skin grafts and erosion and escharosis of graft edges.

Abstract
Objective: To explore the influence of caregiver burden on quality of life among caregivers for patients with lung cancer in Beijing. Methods: From August to October in 2017, 336 caregivers for patients with primary lung cancer from a large tertiary hospital were recruited to this survey by convenient sampling method. The Caregiver Reaction Assessment (CRA) and the WHO Quality of Life-BREF (WHOQOL-BREF) Instruments were used to evaluate the caregiver burden and quality of life. The demographic characteristics were evaluated using Pearson chi-square or Fisher's exact tests. In addition, using the 4 dimensions of quality of life scale as the dependent variables while the 5 dimensions of caregiver burden and demographic variables as the explanatory variables, we conducted the multiple linear stepwise regression analysis (the defaults were 0.15 for FORWARD and BACKWARD). Results: The scores of family caregivers' esteem, impact on schedule, impact on finances, impact on health and lack of family support were 4.30±0.47、3.55±0.74、3.10±0.91、2.60±0.78、2.32±0.73, respectively. Regression results showed that demographic factors, including marriage, occupation and relationship with patients and impact on health, caregivers' esteem and impact on finances dimensions of caregiver burden were the factors which influenced the quality of life of caregivers. Conclusions: The caregiver burden in patients with lung cancer is mainly focused on impact on schedule and finances. Impact on health, finances and caregivers' esteem (seven items were reverse-scored) are significantly negatively correlated with quality of life of caregivers.

Abstract
Objective: To explore the effect of improved V-Y advancement flap with major artery perforator on repairing several skin and soft tissue defects in whole body. Methods: From March 2015 to June 2017, 4 cases with pressure ulcer in sacrococcygeal region, 4 cases with pressure ulcer at ischial tuberosity, 2 cases with scalp and skull defects at occiput, 1 case with secondary wound after tumor resection in axillary region, and 2 cases with skin and soft tissue defects caused by other trauma were hospitalized, with disease duration ranging from 1 week to 6 months. Bones, blood vessels, or nerves were exposed in wounds of 11 cases. After debridement, wounds with area ranging from 5 cm×4 cm to 15 cm×12 cm were repaired by improved V-Y advancement flap with major artery perforator including occipital artery perforator, arteria glutaea perforator, intercostal artery perforator, and peroneal artery perforator, and the area of flap ranged from 11 cm×5 cm to 35 cm×20 cm. Distal end of flaps additionally carried 1 major artery perforator in 4 cases. Results: All flaps survived well without hemodynamic disorder, and wounds and donor sites healed well. During the follow-up for 3 to 18 months, the flaps were good in appearance with similar color and texture to normal skin around wound and without recurrence of rupture. Conclusions: Compared with traditional V-Y advancement flap, the improved V-Y advancement flap with major artery perforator has the advantages of larger repair area, longer advance distance without tension, simple operation, and good appearance after operation, which is beneficial to clinical application.

Abstract
PURPOSE The updated 2013 American Society of Clinical Oncology/College of American Pathologists guideline recommendations for human epidermal growth factor receptor 2 (HER2) testing have made some major changes in HER2 fluorescence in situ hybridization (FISH) interpretation criteria with additional FISH equivocal cases. Repeat HER2 testing is recommended after initial HER2 FISH equivocal results; however, little is known about its impact on final HER2 status. The aim of this study is to investigate whether reflex test clarifies HER2 status, and to characterize clinicopathological features of the newly defined HER2 equivocal group. METHODS A total of 886 consecutive cases of primary invasive breast cancer conducted with dual-probe HER2 FISH testing between November 2013 and December 2015 were reviewed. HER2 immunohistochemistry (IHC) and FISH testing were performed on a different tissue block or a new specimen after initial HER2 FISH equivocal results. RESULTS Compared to 2007 guideline, 85 (9.6%) cases changed their category by using 2013 guideline. The major change of the 85 cases is that 57 (6.4%) cases in HER2 FISH-negative category changed to equivocal, and the equivocal category cases increased from 36 to 67. HER2 FISH equivocal was significantly associated with HER2 IHC equivocal (2+) and chromosome 17 polysomy (P < 0.01). Repeat testing by IHC and FISH clarified HER2 status in 33 and 42% of HER2 equivocal cases, respectively. Overall 32 (48%) initial HER2 equivocal cases stayed HER2 equivocal after repeat FISH and or IHC testing. These tumors were ER/PR+, with high KI-67 index. CONCLUSION New guidelines classify more HER2 FISH equivocal cases. Repeat HER2 testing clarifies HER2 status in about 50% of initial HER2 FISH equivocal cases. In addition, HER2 equivocal cases merit further study as there is limited information about prognosis and optimal treatment strategy for this population.

Abstract
Aim: To investigate the relationship between mutations of key genes in the EGFR signaling pathway and the prognosis of stage II colorectal cancer patients without chemotherapy. Materials & methods: The incidence of KRAS, NRAS, BRAF, PIK3CA mutations and deficient DNA mismatch repair were assessed in 160 stage II colorectal cancer patients who had been treated by radical operation without adjuvant chemotherapy. Results: Mutations in KRAS, BRAF or PIK3CA were associated with poor prognosis, while the deficient DNA mismatch repair status was not associated with the prognosis. Combining these three markers, the sensitivity of the predicted value for poor progression-free survival and overall survival reached 0.645 (p = 0.002) and 0.709 (p = 0.001), respectively. Conclusion: Knowing the mutation status of KRAS, BRAF or PIK3CA in stage II colorectal cancer can significantly improve the accuracy of prognoses.

Abstract
Objective: To study the acute effects of compound ambient air pollution on small airway lung functions among school children in Shanghai. Method: A longitudinal survey on lung functions was conducted among 233 school-children from three schools (A, B and C, located in innerring, mid-ring and outer-ring areas). Lung function test was performed once a week for 3 times respectively, among children in school A and B in Dec. 2013 and in school C in Dec. 2014. The fourth lung function test was tested in Jun. 2014 and May 2015 in the respective schools. Results: from the lung function would include items as: forced mid-expiratory flow at 25% of forced vital capacity (MEF(25%)), mid-expiratory flow at 50% of forced vital capacity (MEF(50%)), mid-expiratory flow at 75% of forced vital capacity (MEF(75%)) and mid-expiratory flow between 25% and 75% of the forced vital capacity (FEF(25%-75%)). Data regarding the daily air quality real-time of PM(2.5), PM(10), SO(2) and NO(2) in Dec. 2013, Dec. 2014, Jun. 2014 and May. 2015 from the three environmental monitoring spots and meteorological data from the Shanghai Meteorological Service system which were physically close to the three schools, were collected simultaneously. Linear mixed effect model was used to examine the levels of correlation between lung function indicators and ambient air pollutants. Results When confounding factors on meteorology and individuals were controlled, the lag effects and accumulated lag effects were found to have existed between the internal quarter rang (IQR) concentration of PM(2.5) and PM(10) in lag2 day and lag02 days, IQR concentration of SO(2) in lag02 day and IQR concentration of NO(2) lag0 day, when small airway lung functions like MEF(25%), MEF(50%), MEF(75%) and FEF(25%-75%)(P<0.05) were inspected. Results from the two air pollutants model analysis showed that SO(2) and NO(2) presenting interactive effects with PM(2.5), PM(10) and lag effects more significant than the individual SO(2) and NO(2), respectively (P<0.05). Conclusion: Contents on the ambient air pollutants as PM(2.5), PM(10), SO(2) and NO(2) were negatively associated with the lung functions in the small airways of children, in Shanghai.

Abstract
Objective: To investigate the epidemiological features of abnormal urinary fluoride rates in population with occupational exposure, and its relationships with age, work years and gender in Shanghai. Methods: A questionnaire survey was conducted respectively in 4 999 exposed workers and 283 non-exposed people during 2012-2015. Their urine samples were collected in plastic bottles and the fluoride ion selective electrode method was used for urinary fluoride level analysis. Logistic regression model was used to estimate associations between the abnormal rates and demographic/socioeconomic status of the study subjects. Results: In the past 4 years, the abnormal urinary fluoride rates (≥1.6 mg/L) in the population with occupational exposure was about 14.38%, it was about 1.43% in the control groups without occupational exposure. Their geometric mean of urinary fluoride content was 0.95 mg/L and 0.46 mg/L, respectively. The incidences of the abnormal rates in those aged ≥50 years and 34-39 years were 19.15% and 22.39%, respectively. The abnormal rate in males was 16.87%, much higher than that in females (6.85%). The abnormal rate had an upward trend along with the increased work years, especially in those with work years of ≥20 years. The abnormal rate was 23.28% in those with work years of ≥20 years and 13.29% in those with work years of <4 years. The relative risk for abnormal urinary fluoride rates was higher in male group, older age group and longer work year group, the odds ratio was 2.28, 1.10 and 1.13, respectively. Conclusions: Serious challenges exist in occupational health supervision. The relevant national standards should be updated as soon as possible. Males, those aged >50 years, and those with longer work years are the risk groups for intervention measures. More efforts are needed, such as strengthening the innovative application of health examination data and the equalization of basic public health service with comprehensive occupational health supervision programs among off-farm workers in the new medical reform.

Abstract
The objective of this paper was to identify hub genes and pathways associated with retinoblastoma using centrality analysis of the co-expression network and pathway-enrichment analysis. The co-expression network of retinoblastoma was constructed by weighted gene co-expression network analysis (WGCNA) based on differentially expressed (DE) genes, and clusters were obtained through the molecular complex detection (MCODE) algorithm. Degree centrality analysis of the co-expression network was performed to explore hub genes present in retinoblastoma. Pathway-enrichment analysis was performed using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Validation of hub gene expression in retinoblastoma was performed by reverse transcription-polymerase chain reaction (RT-PCR) analysis. The co-expression network based on 221 DE genes between retinoblastoma and normal controls consisted of 210 nodes and 3965 edges, and 5 clusters of the network were evaluated. By assessing the centrality analysis of the co-expression network, 21 hub genes were identified, such as SNORD115-41, RASSF2, and SNORD115-44. According to RT-PCR analysis, 16 of the 21 hub genes were differently expressed, including RASSF2 and CDCA7, and 5 were not differently expressed in retinoblastoma compared to normal controls. Pathway analysis showed that genes in 2 clusters were enriched in 3 pathways: purine metabolism, p53 signaling pathway, and melanogenesis. In this study, we successfully identified 16 hub genes and 3 pathways associated with retinoblastoma, which may be potential biomarkers for early detection and therapy for retinoblastoma.

Abstract
Using live eukaryotic cells, including cancer cells, MCF-7 and HCT-116, normal hepatocytes and red blood cells in anode and potassium ferricyanide in cathode of MFC could generate bio-based electric current. Electrons and protons generated from the metabolic reaction in both cytosol and mitochondria contributing to the leaking would mediate the generation of electric current. Both resveratrol (RVT) and 2,4-dinitrophenol (DNP) used to induce proton leak in mitochondria were found to promote electric current production in all cells except red blood cells without mitochondria. Proton leak might be important for electric current production by bringing the charge balance in cells to enhance the further electron leak. The induced electric current by RVT can be blocked by Genipin, an inhibitor of UCP2-mediated proton leak, while that induced by DNP cannot. RVT could reduce reactive oxygen species (ROS) level in cells better than that of DNP. In addition, RVT increased mitochondrial membrane potential (MMP), while DNP decreased it. Results highly suggested the existence of at least two types of electric current that showed different properties. They included UCP2-mediated and non-UCP2-mediated electric current. UCP2-mediated electric current exhibited higher reactive oxygen species (ROS) reduction effect per unit electric current production than that of non-UCP2-mediated electric current. Higher UCP2-mediated electric current observed in cancer cells might contribute to the mechanism of drug resistence. Correlation could not be established between electric current production with either ROS and MMP without distinguishing the types of electric current.

Abstract
This study was undertaken to investigate the effects of ambient temperature, crude protein levels and their interaction on performance and serum biochemical parameters of broiler chickens. A total of 216 Arbor Acre broiler chickens (108 males and 108 females) were used in a 2 × 3 factorial arrangement and randomly reared at two temperatures (normal temperature: 23 °C; daily cyclic high temperature: 28-32 °C) and fed on three diets with different crude protein levels (153.3, 183.3 or 213.3 g/kg, with constant essential amino acids) from 28 to 42 days of age. Daily cyclic high ambient temperature decreased final body weight, average daily weight gain, average daily feed intake and serum total protein contents (p < 0.001, p < 0.001, p < 0.001, p = 0.008 respectively), but increased feed/gain, mortality, respiratory rate, rectal temperature, serum uric acid contents and serum creatine kinase activity (p = 0.008, p = 0.003, p < 0.0001, p < 0.0001, p < 0.0001, p = 0.003 respectively), irrespective of crude protein levels. At the ambient temperature, reducing crude protein levels resulted in an increase in feed/gain (p < 0.001), but a decrease in serum total protein and uric acid contents. Only serum creatine kinase activity in broiler chickens was interacted by daily cyclic high ambient temperature and dietary crude protein levels (p = 0.003). These results indicated that daily cyclic high ambient temperature had a great effect on performance and serum biochemical parameters in broiler chickens, whereas dietary crude protein levels affected them partially.
