Abstract
BACKGROUND Coronary heart disease (CHD) has become a worldwide public health problem. Genetic factors are considered important risk factors for CHD. The aim of this study was to explore the correlation between CYP4A22 gene polymorphism and CHD susceptibility in the Chinese Han population. METHODS We used SNPStats online software to complete the association analysis among 962 volunteers. False-positive report probability analysis was used to confirm whether a positive result is noteworthy. Haploview software and SNPStats were used for haplotype analysis and linkage disequilibrium. Multi-factor dimensionality reduction was applied to evaluate the interaction between candidate SNPs. RESULTS In overall and some stratified analyses (male, age ≤ 60 years or CHD patients complicated with hypertension), CYP4A22-rs12564525 (overall, OR = 0.83, p-value is 0.042) and CYP4A22-rs2056900 (overall, OR = 1.22, p-value is 0.032) were associated with the risk of CHD. CYP4A22-4926581 was associated with increased CHD risk only in some stratified analyses. FPRP indicated that all positive results in our study are noteworthy findings. In addition, MDR showed that the single-locus model composed of rs2056900 is the best model for predicting susceptibility to CHD. CONCLUSION There are significant associations between susceptibility to CHD and CYP4A22 rs12564525, and rs2056900.

Abstract
Diabetic kidney disease is one of the complications of diabetes mellitus, which can eventually progress to end-stage kidney disease. The increasing prevalence of diabetic kidney disease has brought huge economic burden to society and seriously jeopardized public health. Ferroptosis is an iron-dependent, non-apoptosis-regulated form of cell death. The regulation of ferroptosis involves different molecular mechanisms and multiple cellular metabolic pathways. In recent years, ferroptosis has been proved to be closely related to the occurrence and development of diabetic kidney disease, and can interact with pathological changes such as fibrosis, inflammation, oxidative stress, and disorders of glucose and lipid metabolism, destroying the structure, form and function of the inherent cells of the kidney, and promoting the progression of the disease. Traditional Chinese medicine has a long history of treating diabetic kidney disease with remarkable curative effect. Current scholars have shown that the oral administration of traditional Chinese medicine and the external treatment of Chinese medicine can regulate GPX4, Nrf2, ACSL4, PTGS2, TFR1 and other key signaling molecules, curb ferroptosis, and prevent the progressive deterioration of diabetic kidney disease. In this paper, the mechanism of ferroptosis and diabetic kidney disease and the prevention and treatment of traditional Chinese medicine are analyzed and summarized, in order to provide new ideas and new plans for the treatment of diabetic kidney disease.

Abstract
Rapid and sensitive dengue non-structural protein 1 (NS1) detection assay is essential for the treatment of disease and currently releases high medical cost burdens. To address the limitations of conventional LFIA strips, we have developed an improved Sup35NM-Z-based LFIA that immobilizes antibodies on cellulose membranes in an orientated manner to increase the sensitivity of LFIA strips. A dual-functional Sup35NM nanofibril was fabricated by fusion with the antibody binding domain; resultant nanofibril from the amyloid Sup35NM was sprayed on the T-line to orientate the capture antibody and produces fluorescence signals. Antibody binding analysis showed that self-assembly of the Sup35NM monomer does not affect the binding activity of the Z-domain with the antibody. The NS1 for DENV-2 infection was chosen as a model target antigen to assess the feasibility of the Sup35NM-Z-domain-based LFIA platform. Under optimal conditions, the Sup35NM-Z-domain-based LFIA detected NS1 within 15 min with a detection limit of 1.29 ng/ml, while the detection limit of traditional LFIA with the same concentration of anti-NS1-Ab1 on the T-line by conventional physical adsorption was 2.20 ng/ml, 1.7 times higher than that of Sup35NM-Z-domain-based LFIA. As compared to traditional LFIAs, the Sup35NM-Z-based LFIA had a wide detection range of 1.29-625 ng/mL. The LFIA's clinical performance in identifying NS1 was also assessed using 15 clinical samples. The LFIA accurately recognized positive and negative samples, equal to 86.7% accuracy. The developed Sup35NM-Z-domain-based LFIA in this study offers great potential for the identification of target markers because of its greatly improved sensitivity and wider detection range.

Abstract
Background: Prenatal diagnosis and genetic counseling play an important role in preventing and controlling birth defects. No reports were found of prenatal diagnosis of couples carrying both the thalassemia and deafness genes. In this study, we presented the prenatal screening and diagnosis of a couple with both thalassemia and deafness genes, contributing to better genetic counseling. Case Report: A couple visited our hospital for a routine prenatal examination. As required by the policy in our region, they underwent screening and genetic diagnosis for thalassemia. Meanwhile, they did not accept the recommendation to test for spinal muscular atrophy and deafness genes. The female was confirmed to be a Hb Quong Sze (Hb QS) carrier (αQSα/αα, βN/βN), and the male had Hb H disease combined with β-thalassemia (--SEA/αCSα, βCDs41-42 (-TTCT)/βN). A prenatal diagnosis of the fetus revealed a Hb CS heterozygote. Subsequent complementary testing showed that the male was a double heterozygote of the GJB2 gene c.299_300delAT combined with c.109G>A, and Sanger sequencing confirmed that the female was a carrier of c.508_511dup in the GJB2. Fortunately, the chorionic villi results indicated that the fetus was only a carrier of deafness. Conclusion: Since both partners carried thalassemia and deafness genes, the couple required prenatal diagnosis for the respective mutations. Expanded carrier screening (ECS) is a more advanced technology that can detect multiple disease genes simultaneously.

Abstract
PURPOSE The research aimed to detect the association between single nucleotide polymorphisms (SNPs) in CYP4V2 gene and coronary heart disease (CHD) risk. METHODS This case-control study included 487 CHD subjects and 487 healthy individuals. Logistic regression was performed to analyze the connection between five SNPs in CYP4V2 (rs1398007, rs13146272, rs3736455, rs1053094, and rs56413992) and CHD risk, and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to evaluate the connection. RESULTS As a result, we found that rs56413992 T allele (OR = 1.36, 95% CI = 1.09-1.70, p = 0.007) and CT genotype (OR = 1.40, 95% CI = 1.06-1.83, p = 0.017) were significantly associated with an increased risk of CHD in the overall analysis. Precisely, rs56413992 was linked to an elevated risk of CHD in people aged > 60, males, smokers and drinkers. The study also indicated that rs1398007 was linked to an increased CHD risk in drinkers. In addition, rs1053094 was correlated with a decreased risk of CHD complicated with diabetes mellitus (DM), and rs1398007 was correlated with a decreased risk of CHD complicated with hypertension (HTN). CONCLUSION This study was the first to experimentally demonstrate that CYP4V2 rs56413992 was associated with the risk of CHD, which will provide a certain reference for revealing the pathogenesis of CHD.

Abstract
Ischemic stroke is one of the main causes of mortality and disability worldwide. However, the majority of patients are currently unable to benefit from intravenous thrombolysis or intravascular mechanical thrombectomy due to the limited treatment windows and serious complications. Silent mating type information regulation 2 homolog 1 (Sirt1), a nicotine adenine dinucleotide-dependent enzyme, has emerged as a potential therapeutic target for ischemic stroke due to its ability to maintain brain homeostasis and possess neuroprotective properties in a variety of pathological conditions for the central nervous system. Animal and clinical studies have shown that activation of Sirt1 can lessen neurological deficits and reduce the infarcted volume, offering promise for the treatment of ischemic stroke. In this review, we summarized the direct evidence and related mechanisms of Sirt1 providing neuroprotection against cerebral ischemic stroke. Firstly, we introduced the protein structure, catalytic mechanism and specific location of Sirt1 in the central nervous system. Secondly, we list the activators and inhibitors of Sirt1, which are primarily divided into three categories: natural, synthetic and physiological. Finally, we reviewed the neuroprotective effects of Sirt1 in ischemic stroke and discussed the specific mechanisms, including reducing neurological deficits by inhibiting various programmed cell death such as pyroptosis, necroptosis, ferroptosis, and cuproptosis in the acute phase, as well as enhancing neurological repair by promoting angiogenesis and neurogenesis in the later stage. Our review aims to contribute to a deeper understanding of the critical role of Sirt1 in cerebral ischemic stroke and to offer novel therapeutic strategies for this condition.

Abstract
Bacterial quorum sensing (QS) plays a crucial role in chemical communication between bacteria involving autoinducers and receptors and controls the production of virulence factors in bacteria. Therefore, reducing the concentration of signaling molecules in QS is an effective strategy for mitigating the virulence of pathogenic bacteria. In this study, we demonstrated that carvacrol at 15.625 μg/mL (1/4 MIC), a natural compound found in plants, exhibits potent inhibitory activity against QS in Chromobacterium violaceum, as evidenced by a significant reduction (62.46%) in violacein production. Based on its impressive performance, carvacrol was employed as a natural QS inhibitor to suppress the pathogenicity of Aeromonas hydrophila NJ-35. This study revealed a significant reduction (36.01%) in the concentration of N-acyl-homoserine lactones (AHLs), a QS signal molecular secreted by A. hydrophila NJ-35, after 1/4 MIC carvacrol treatment. Moreover, carvacrol was found to down-regulate the expression of ahyR/I, two key genes in the QS system, which further inhibited the QS system of A. hydrophila NJ-35. Finally, based on the above results and molecular docking, we proposed that carvacrol alleviate the pathogenicity of A. hydrophila NJ-35 through QS inhibition. These results suggest that carvacrol could serve as a potential strategy for reducing the virulence of pathogenic bacteria and minimizing the reliance on antibiotics in aquaculture.

Abstract
Background The pathophysiological mechanism of ischemic stroke is complex. Traditional risk factors cannot fully or only partially explain the occurrence and development of IS. Genetic factors are getting more and more attention. Our study aimed to explore the association between CYP4F2 gene polymorphism and susceptibility to IS. Methods A total of 1322 volunteers were enrolled to perform an association analysis through SNPStats online software. Using FPRP (false-positive report probability) to detect whether the result is a noteworthy finding. The interaction of SNP-SNP in IS risk was assessed by multi-factor dimensionality reduction. Statistical analysis of this study was mainly completed by SPSS 22.0 software. Results Mutant allele "A" (OR = 1.24) and genotype "AA" (OR = 1.49) or "GA" (OR = 1.26) of CYP4F2-rs2108622 are risk genetic factors for IS. Rs2108622 is significantly associated with an increased risk of IS among subjects who are females, aging >60 years old, with BMI ≥24 kg/m2, and smoking or drinking volunteers. CYP4F2-rs3093106 and -rs3093105 are associated with susceptibility to IS among smoking, drinking subjects, or IS patients complicated with hypertension. Conclusion CYP4F2-rs2108622, -rs3093106, and -rs3093105 are associated with an increased risk of IS.

Abstract
Introduction Ischemic stroke (IS) is a multifactorial and polygenic disease, which is affected by genetic factors. In this study, we explored the role of CYP19A1 single nucleotide polymorphisms (SNPs) in IS in the Chinese population. Methods 1302 subjects (651 controls and 651 cases) were recruited in this case-control study. Four candidate SNPs (rs28757157 C/T, rs3751592 C/T, rs3751591 G/A, rs59429575 C/T) of CYP19A1 were selected by the 1000 genomes project database. The association between CYP19A1 SNPs and IS risk was assessed using logistic regression analysis with odds ratio (OR) and 95% confidence intervals (CIs). False-positive report probability (FPRP) analysis further verified the positive results. The interaction of SNP-SNP was analyzed by multi-factor dimensionality reduction (MDR) to predict is risk. Results In the research, CYP19A1 loci (rs28757157 and rs3751591) were associated with the occurrence of IS. The two variants conferred an increased susceptibility to IS in the subjects aged over 60 years old, smokers and drinkers. Rs28757157 was related to the risk of IS in females, non-smokers and subjects with BMI less than 24, while rs59429575 was related to the risk of IS in males and subjects with BMI greater than 24. Conclusion The study revealed that there is a significant association between CYP19A1 loci (rs28757157 and rs3751591) and IS risk in the Chinese Han population, providing a theoretical basis for further exploring its specific role in the pathogenesis of IS.

Abstract
Objective: To establish and optimize a TaqMan-probe quantitative real-time PCR (qPCR) assay for the detection of 7 important Rickettsiales pathogens and simultaneous identification of the infection types. Methods: Based on the ompB gene of Rickettsia prowazekii, Rickettsia mooseri and spotted fever group rickettsiae, the groEL gene of Orientia tsutsugamushi, the 16S rRNA of Ehrlichia chaffeensis, the gltA gene of Anaplasma phagocytophilum and the com1 gene of Coxiella burnetii, we synthesized primers and TaqMan-probes and optimized the reaction system and reaction process to same solution. The sensitivity, specificity and reproducibility of this assay were evaluated and the assay was used for the detection of simulated and actual samples. Results: The Ct value of the standard curves of the 7 pathogens showed a good linear relationship with the number of DNA copies (all R2 >0.990 0), the minimum detection limit was 10 copies/μl, showing good specificity. In the 96 tick nucleic acid extracts, Coxiella burnetii was detected in 1 sampleand spotted fever group Rickettsiae was detected in 3 samples. In the 80 blood samples from patients with undefined febrile illness, Orientia tsutsugamushi was detected in 1 sample and spotted fever group rickettsiae was detected in 2 samples. Conclusions: In this study, based on the established TaqMan-probe qPCR assay, the reaction system and reaction condition of the 7 important pathogens of Rickettsiales were optimized to the same solution. This method overcomes the shortcomings of using different reaction systems and reaction conditions for different pathogens, which can precisely identify the species of 7 important pathogens of Rickettsiales in clinical sample detections and is important for the infection type identification and laboratory detection time reduction to facilitate precise treatment of the patients.

Abstract
Drug-induced liver injury (DILI) is one of the most common adverse drug reactions that may seriously threaten the health of children and is receiving increasing clinical attention day by day. There is still no independent diagnosis and treatment guideline for DILI in children, but its clinical features are not completely similar to those in adults. This article reviews the epidemiology, clinical features, diagnosis, and treatment progress in order to provide a reference for the management of DILI in children.

Abstract
OBJECTIVES We aimed to discuss the correlation between the Hemophilia Early Detection Ultrasound in China (HEAD-US-C) score and the Hemophilia Joint Health Score version 2.1 (HJHS 2.1) of the knee joint in patients with hemophilia. METHODS We included 70 male patients with hemophilia admitted to The Second Hospital of Shanxi Medical University; the patients' bilateral knee joints were evaluated using the HEAD-US-C score and HJHS. We analyzed factors influencing hemophilia arthropathy of the knee and examined the correlation between the HEAD-US-C score and HJHS. RESULTS The joint injury severity was positively correlated with age and the number of bleeds (P < .001). Further, the HEAD-US-C score and HJHS differed according to the severity (both P < .001), but not type (P = .163 and P = .283, respectively), of hemophilia. There was a significant correlation between the HEAD-US-C score and HJHS (P < .001). CONCLUSIONS Overall, all joint lesions observed on ultrasound corresponded to clinical joint functional abnormalities. Therefore, the HEAD-US-C is important for hemophilic arthropathy evaluation and is useful in explaining abnormal joint function.

Abstract
Aeromonas hydrophila is a Gram-negative bacterium that widely exists in various aquatic environments and causes septicemia in fish and humans. Resveratrol, a natural polyterpenoid product, has potential chemo-preventive and antibacterial properties. In this study, we investigated the effect of resveratrol on A. hydrophila biofilm formation and motility. The results demonstrated that resveratrol, at sub-MIC levels, can significantly inhibit the biofilm formation of A. hydrophila, and the biofilm was decreased with increasing concentrations. The motility assay showed that resveratrol could diminish the swimming and swarming motility of A. hydrophila. Transcriptome analyses (RNA-seq) showed that A. hydrophila treated with 50 and 100 μg/mL resveratrol, respectively, presented 230 and 308 differentially expressed genes (DEGs), including 90 or 130 upregulated genes and 130 or 178 downregulated genes. Among them, genes related to flagellar, type IV pilus and chemotaxis were significantly repressed. In addition, mRNA of virulence factors OmpA, extracellular proteases, lipases and T6SS were dramatically suppressed. Further analysis revealed that the major DEGs involved in flagellar assembly and bacterial chemotaxis pathways could be regulated by cyclic-di-guanosine monophosphate (c-di-GMP)- and LysR-Type transcriptional regulator (LTTR)-dependent quorum sensing (QS) systems. Overall, our results indicate that resveratrol can inhibit A. hydrophila biofilm formation by disturbing motility and QS systems, and can be used as a promising candidate drug against motile Aeromonad septicemia.

Abstract
Objective: To analyze the epidemiological characteristics of typhus in China from 1950 to 2021, and discuss the challenges in typhus prevention and control in China and suggest future prevention and control strategies. Methods: Based on the reported data of typhus from 1950 to 2021 in China from the Infectious Disease History Database of China Public Health Science Data Center and the National Notifiable Infectious Disease Reporting Information System of Chinese Center for Disease Control and Prevention, we conducted a descriptive statistical analysis. Mann-Kendall test and circular distribution method were used to analyze the incidence, mortality and case fatality of typhus to reveal the temporal, spatial and population distributions and diagnosis of typhus in China. Results: From 1950 to 2021, a total of 452 965 typhus cases and 7 339 typhus deaths were reported in China, with the cases numbers exceeding 10 000 in 14 years of the 1950s, 1960s and 1980s, respectively. Since 1990s, the reported cases and incidence rate of typhus have decreased dramatically and the most cases were sporadic. However, the reported typhus cases in Anhui, Hubei, Hunan Provinces showed significant uptrends. Although typhus could occur all the year round, but the seasonality was observed with the incidence mainly in summer and autumn. For different provinces from the north to the south, the peaks of typhus' monthly incidence tended to shift to earlier dates. The male to female ratio of the cases was 1.01∶1 (18 529∶18 366). However, more cases occurred in women in recent years. The cases aged ≤9 years accounted for the highest proportion (18.9%), but the number of cases aged ≥50 years showed an upward trend. Most cases were farmers with the proportion increasing year by year. Moreover, the cases in students and scattered-living children also accounted for relatively higher proportions. The median of the interval between onset and diagnosis of typhus was 6 days. Most cases were clinically diagnosed, while the proportion of laboratory-confirmed cases was low and most laboratory cases were confirmed by Well-Felix reaction. Conclusions: Although the incidence and mortality of typhus in China has decreased significantly, the risk for local typhus outbreaks still exists. The prevention and control of typhus still face many challenges. It is indispensable to strengthen the pathogen detection and surveillance for typhus in China.

Abstract
Aeromonas hydrophila is a significant pathogen to freshwater farmed animals, and antibiotics are usually used to control the bacterial septicemia caused by A. hydrophila. Due to the severe situation of development and spread of antibiotic resistance, there are stricter restrictions on antibiotics used in aquaculture. To evaluate the feasibility of glycyrrhetinic acid β (GA) as an alternative therapy against bacterial infection, in this study, an A. hydrophila isolated from diseased fish is used to test the antibacterial, anti-virulence activity and therapeutic effect of GA in vitro and in vivo, respectively. Results showed that GA did not affect the growth of A. hydrophila in vitro, while it could down-regulate (p < 0.05) the mRNA expression of the hemolysis-related genes hly and aerA, and significantly inhibited (p < 0.05) hemolytic activity of A. hydrophila. In addition, in vivo test showed that oral administration of GA was ineffective in controlling acute infections caused by A. hydrophila. In conclusion, these findings suggested that GA was a potential anti-virulence candidate against A. hydrophila, but the application of GA for the prevention and treatment of A. hydrophila-related diseases was still a long way.

Abstract
AIMS To assess the difference in survival between fertility-sparing surgery (FSS) and radical surgery and explore pregnancy outcomes after FSS in stage I malignant sex cord-stromal tumours (MSCSTs). MATERIALS AND METHODS We carried out a multicentre retrospective cohort study on patients who were diagnosed with MSCSTs and the tumour was confined to one ovary. The patients were divided into FSS and radical surgery groups. Inverse probability of treatment weighting (IPTW) was used to balance variables between the two groups. Kaplan-Meier analysis was used to compare the difference in disease-free survival (DFS). Univariate and multivariate Cox regression analysis was used to find risk factors of DFS. Univariate logistic regression analysis was used to assess risk factors of pregnancy. RESULTS In total, 107 patients were included, of whom 54 (50.5%) women underwent FSS and 53 (49.5%) received radical surgery. After IPTW, a pseudo-population of 208 was determined and all of the covariates were well balanced. After a median follow-up time of 50 months (range 7-156 months), 10 patients experienced recurrence and two died. There was no significant difference in DFS between the two groups, both in unweighted (P = 0.969) or weighted cohorts (P = 0.792). In the weighted cohort, stage IC (P = 0.014), tumour diameter >8 cm (P = 0.003), incomplete staging surgery (P = 0.003) and no adjuvant chemotherapy (P < 0.001) were the four high-risk factors associated with a shorter DFS. Among 14 patients who had pregnancy desire, 11 (78.6%) women conceived successfully; the live birth rate was 76.9%. In univariate analysis, only adjuvant chemotherapy (P = 0.009) was associated with infertility. CONCLUSIONS On the premise of complete staging surgery, FSS is safe and feasible in early stage MSCSTs with satisfactory reproductive outcomes.

Abstract
Objective: To compare the differences to determine resting energy expenditure (REE) measured with indirect calorimetry and REE predicted by formula method and body composition analyzer in patients with decompensated hepatitis B cirrhosis, so as to provide theoretical guidance for the implementation of precision nutrition intervention. Methods: Patients with decompensated hepatitis B cirrhosis who were admitted to Henan Provincial People's Hospital from April 2020 to December 2020 were collected. REE was determined by the body composition analyzer and the H-B formula method. Results: were analyzed and compared to REE measured by the metabolic cart. Results A total of 57 cases with liver cirrhosis were included in this study. Among them, 42 were male, aged (47.93 ± 8.62) years, and 15 were female aged (57.20 ± 11.34) years. REE measured value in males was (1 808.14 ± 201.47) kcal/d, compared with the results calculated by the H-B formula method and the measured result of body composition, and the difference was statistically significant (P = 0.002 and 0.003, respectively). REE measured value in females was (1 496.60 ± 131.28) kcal/d, compared with the results calculated by the H-B formula method and the measured result of body composition, and the difference was statistically significant (P = 0.016 and 0.004, respectively). REE measured with the metabolic cart had correlation with age and area of visceral fat in men (P = 0.021) and women (P = 0.037). Conclusion: Metabolic cart use will be more accurate to obtain resting energy expenditure in patients with decompensated hepatitis B cirrhosis. Body composition analyzer and formula method may underestimate REE predictions. Simultaneously, it is suggested that the effect of age on REE in H-B formula should be fully considered for male patients, while the area of visceral fat may have a certain impact on the interpretation of REE in female patients.

Abstract
BACKGROUND BSN-37, a novel antimicrobial peptide (AMP) containing 37 amino acid residues isolated from the bovine spleen, has not only antibacterial activity but also immunomodulatory activity. Recent evidence shows that long non-coding RNAs (lncRNAs) play an important role in regulating the activation and function of immune cells. The purpose of this experiment was to investigate the lncRNA and mRNA expression profile of mouse macrophages RAW264.7 stimulated by bovine antimicrobial peptide BSN-37. METHODS The whole gene expression microarray was used to detect the differentially expressed lncRNA and mRNA between antimicrobial peptide BSN-37 activated RAW264.7 cells and normal RAW264.7 cells. KEGG pathway analysis and GO function annotation analysis of differentially expressed lncRNAs and mRNA were carried out. Eight kinds of lncRNAs and nine kinds of mRNA with large differences were selected for qRT-PCR verification, respectively. RESULTS In the current study, we found that 1294 lncRNAs and 260 mRNAs were differentially expressed between antibacterial peptide BSN-37 treatment and control groups. Among them, Bcl2l12, Rab44, C1s, Cd101 and other genes were associated with immune responses and were all significantly up-regulated. Mest and Prkcz are related to cell growth, and other genes are related to glucose metabolism and lipid metabolism. In addition, some immune-related terms were also found in the GO and KEGG analyses. At the same time, real-time quantitative PCR was used to verify selected lncRNA and mRNA with differential expression. The results of qRT-PCR verification were consistent with the sequencing results, indicating that our data were reliable. CONCLUSION This study provides the lncRNA and mRNA expression profiles of RAW264.7 macrophages stimulated by antimicrobial peptide BSN-37 and helps to provide a reference value for subsequent studies on lncRNA regulation of antimicrobial peptide BSN-37 immune function.

Abstract
OBJECTIVES To report the hematolgocial and molecular features of a nove β-globin variant in a Chinese fimaly. METHODS The proband was a 19-year-old Chinese man whose Hb analysis by HPLC for thalassemia revealed an abnormal peak. Hb analysis was performed by HPLC and CE. Gap-PCR and PCR-reverse dot blot hybridization (PCR-RDB) were used to detect the common mutations in Chinese population. DNA sequencing was used to determine the Hb variant. RESULTS The Hb variant and Hb A can be separated but co-elutes with Hb F by the CE method. However, the variant can be separated from Hb A0, Hb F, and Hb A2 using HPLC. DNA sequencing showed a mutation of codon 3 in the β-globin gene. His wife's HPLC revealed a high value of Hb A2, which proved to be the Hb E using PCR-RDB. CONCLUSION It was the first report of the mutation, so we named it Hb Jiangnan according to the place of residence of the proband. It can be separated by HPLC but not CE. Hb Jiangnan can cause an increased level of Hb A2.

Abstract
Purpose COVID-19 posed a threat to the public’s physical and mental health, and under outbreak control, the opportunities to go outside of the elderly have been reduced and making it more difficult to access health information and detrimental to their health management. This study aims to assess the current status of health information literacy (HIL) among older adults in the community in the context of COVID-19 and to identify its associated factors. Methods A cross-sectional survey was conducted from April to July, 2021, for which 617 community elderly members were recruited in Chenzhou, China. Data were collected through a general information questionnaire, The Chinese residents’ HIL self-rated scale and a reliability evaluation form. Results The average score of HIL was 75.87 ± 9.85, and after processed by the 100-point system, we found 84.12% (519/617) of the participants scored less than 60 points, which indicates that the overall level of HIL among the community elderly is low. Multiple linear regression showed that age, gender, education, annual family Income, living arrangement, and chronic disease status (β = –0.341, –0.296, 0.384, 0.327, 0.296, 0.356, respectively; all P < 0.001) were significantly associated with the level of HIL found among the community elderly, out of which education was the most important associated factor. Conclusion The overall HIL level among the community elderly was low in Central China during the COVID-19 pandemic. Our results further prove the need for tailor-made health education programs for this group, with particular attention paid to the low-educated and low-income among them. Those measures must highlight on three aspects of health information search, evaluation, and application skills to offer useful experiences that improve the HIL level of the elderly and strengthen their ability to cope with emerging public health events.

Abstract
Aeromonas hydrophila is a ubiquitous Gram-negative opportunistic pathogen in the freshwater environment and the most common cause of bacterial septicemia in aquaculture. In this study, we investigated the impact of carvacrol, a natural monoterpenoid found in herbs, on the virulence of A. hydrophila in vitro and the antibacterial effect in combination with antibiotics. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of carvacrol against A. hydrophila NJ-35 were 125 µg/mL and 250 µg/mL, respectively. Carvacrol could inhibit the virulence factors (biofilm, protease, exopolysaccharide, and hemolysin) of A. hydrophila, and the antibiofilm potential of carvacrol was further verified by microscopic detection. Transcriptional analyses showed that the gene expression of flaB, ompA, aha, ahp, ela, act, aerA, AhyR, and hly were marked as downregulated. The checkerboard assay results showed that carvacrol did not have an antagonistic effect in combination with antibiotics (florfenicol, enrofloxacin, thiamphenicol, or doxycycline hydrochloride) commonly used in aquaculture but possessed an additive-synergistic effect with neomycin sulfate. In vivo studies demonstrated that carvacrol protected grass carp (Ctenopharyngodon idella) from A. hydrophila infection. Our results indicated that carvacrol possessed significant anti-bacterial and anti-virulence effects on A. hydrophila.

Abstract
Background Hemoglobin H (Hb H) disease is a moderate‐to‐severe form of α‐thalassemia (α‐thal), and parts of patients may require intermittent transfusion therapy, especially during intercurrent illness. However, rare Hb H diseases remain undetected using routine methods being outside of the testing scope. In this study, we present an approach to detecting Hb H disease by long molecule sequencing (LMS). Methods A total of 206 known genotype samples were collected and carried to blind detected by LMS on the PacBio Sequel platform. Circular consensus sequencing reads were aligned to the hg19 reference genome using Free‐Bayes finished LMS. LMS accuracy would be compared with routine methods, including Gap‐PCR and PCR‐Reverse dot blot hybridization (PCR–RDB). Results The assay could detect carriers of both deletion and point mutations. It had an overall accuracy of 100% when compared with routine methods. In addition, LMS detected six mutations based on routine methods and corrected three case results. Hb H diseases were identified using LMS, whether a common or rare genotype, a deletion or non‐deletion genotype. However, two cases of Hb H disease were misdiagnosed using routine methods. Conclusions Long molecule sequencing can be suggested as a rapid and reliable assay to detect probable carriers of hemoglobinopathies. LMS accurately identified the common and rare genotypes of Hb H disease.

Abstract
BACKGROUND Readiness for hospital discharge is associated with patients' health outcomes after they return home. However, little is known about this association among cancer patients receiving oral chemotherapy at home. This study aimed to examine whether patients' reported readiness for hospital discharge was associated with symptoms and non-routine utilization of post-discharge services among cancer patients receiving oral chemotherapy at home. METHODS A prospective study was conducted, and 151 cancer patients receiving oral chemotherapy were recruited from a provincial level hospital in South China between October 2018 and December 2019. The primary outcome was readiness for hospital discharge assessed by the Readiness for Hospital Discharge Scale-Short Form on the day of discharge. The secondary endpoints were symptoms assessed by MD Anderson Symptom Inventory and non-routine utilization of post-discharge services within one cycle of chemotherapy at home (21 days). RESULTS Among these 151 participants, 74.2% of them reported as ready for discharge. Patients who were employed, lived in suburban area or villages, had a higher Eastern Cooperative Oncology Group score, took Tegafur as oral chemotherapy, and took oral chemotherapy for the first time reported lower readiness for hospital discharge. These five factors explained 28.1% of variance in readiness for hospital discharge. Patients who were not ready for discharge were prone to report higher symptom severity (p = 0.038). No differences in non-routine utilization of post-discharge services were found between the readiness versus non-readiness for discharge groups (p = 0.891). CONCLUSIONS Most cancer patients receiving oral chemotherapy at home were ready for discharge, which was influenced by employment status, residence status, Eastern Cooperative Oncology Group score, type of oral chemotherapy drug, and the experience of taking oral chemotherapy at home. Patients with lower readiness reported worse symptom severity at home. Routine assessment was suggested to recognize unready patients, and more extensive preparations for discharge were recommended to help them manage symptoms at home.

Abstract
Driven by the urgent need for adaptive infrared (IR) electrochromic devices, the improvement in electrochromic performance based on polyaniline (PANI) conducting polymers has become an outstanding challenge. In recent years, the acid doping strategy has been proven to increase the IR modulation ability of PANI, in particular for the Bronsted acid doping. Herein, the effects of copper ions, a Lewis acid, on the structure and electrochromic properties of polyaniline were investigated. Compared to pure polyaniline, the Cu-doped PANI porous films show better IR modulation ability. With the increasing concentration of copper ions, the Cu-doped PANI porous films exhibit a trend in volcanic patterns for the emittance variation (∆ε), depending on the number of polarons and bipolarons. The optimal IR emissivity (ε) modulation obtained on Cu-doped PANI films shows the ∆ε modulation of 0.35 and 0.3 in the wavelength range of 8-14 µm and 2.5-25 µm, superior to previously reported pure sulfuric acid-doped PANI. Furthermore, a flexible IR electrochromic device was fabricated with the present Cu-doped PANI porous films. The modulation of the emittance variation varied between 0.513 and 0.834 (∆ε = 0.32 in ranges of wavelength 8-12 µm), suggesting the great potential for applications in military camouflage and intelligent IR thermal management. We believe that the results in this work will provide a novel perspective and avenue for improving the IR modulation ability of electrochromic devices based on polyaniline conducting polymers.

Abstract
Objective A retrospective case-control study was performed to observe the effect and clinical significance of early electroacupuncture combined with enhanced recovery after surgery (ERAS) on pain perception and dysfunction after total knee arthroplasty (TKA). Methods About 100 patients who diagnosed with TKA from February 2019 to April 2021 were enrolled in our hospital. The patients were arbitrarily assigned into control group and study group. The former group was cured with electroacupuncture in the early stage, and the latter group was intervened on the basis of early electroacupuncture combined with the concept of ERAS. The curative effect, the time of getting out of bed for the first time after operation, the time of postoperative rehabilitation, postoperative rehabilitation cost, pain score and knee joint function score, range of motion (ROM) of knee joint, low shear of whole blood viscosity, plasma viscosity, fibrinogen level, and postoperative complications were compared. Results There exhibited no statistical difference in clinical data. In terms of the treatment effects, there were 27 cases of markedly effective, 22 cases of effective, and 1 case of ineffective in the study group, and the total effective rate was 98.00%; in the control group, 15 cases were markedly effective, 28 cases were effective, and 13 cases were ineffective, and the total effective rate was 86.00%. Compared to the control group, the total effective rate of the study group was higher (P < 0.05). And the first time to get out of bed and the postoperative rehabilitation time in the study group were lower. Compared to the control group (10113.42 ± 524.83) yuan, the postoperative rehabilitation cost in the study group (12401.71 ± 530.77) yuan was higher. In terms of the scores of VAS and HSS, there exhibited no remarkable difference before treatment (P > 0.05). After treatment, the VAS score lessened and the HSS score augmented the study group VAS score (1.76 ± 0.28); the score in the control group was lower compared to the control group (3.45 ± 0.36), and HSS scoring (83.48 ± 11.23) points higher compared to the control group (65.82 ± 10.44) points (P < 0.05). The ROM of knee joint augmented successively at the 1st, 2nd, 4th, and 8th week after treatment comparison between groups, the ROM of the knee joint in the study group at the 1st, 2nd, 4th, and 8th week was (49.47 ± 3.60)°, (64.38 ± 5.32)°, (86.93 ± 6.72)°, and (104.20 ± 9.11)°, is higher compared to the control group (46.53 ± 3.41)°, (61.52 ± 5.20)°, (78.42 ± 6.45)°, and (98.77 ± 8.67)° (P < 0.05). One day after operation, there exhibited no remarkable difference in whole blood viscosity low shear, plasma viscosity, and fibrinogen level (P > 0.05). However, there exhibited no remarkable difference in plasma viscosity and fibrinogen level at 1 day and 7 days after operation (P > 0.05). Seven days after operation, the whole blood viscosity, plasma viscosity, and fibrinogen in the study group were lower (P < 0.05). The probability of postoperative complications was compared. In the study group, there were 2 cases of limb swelling and pain, 1 case of joint stiffness, and no swelling and pain complicated with deep venous thrombosis, and the total incidence was 6.00%. In the control group, there were 5 cases of limb swelling and pain, 3 cases of joint stiffness, and 3 cases of swelling and pain complicated with deep venous thrombosis, with a total incidence of 22.00%. The incidence of adverse reactions in the study group was lower (χ 2 = 5.317 P < 0.05). Conclusion Early electroacupuncture combined with ERAS is of positive significance to the patients after TKA, which can reduce the pain, enhance the function of the knee joint, and promote the ROM of the knee joint, and can effectively shorten the first time out of bed and postoperative rehabilitation time and reduce whole blood viscosity low shear, plasma viscosity, and fibrinogen level, but the overall rehabilitation cost is high, and clinical application should be combined with the actual situation of patients.

Abstract
The activation of artemisinin and its derivatives (ARTs) to generate ROS and other free radicals is mainly heme- or ferrous iron-dependent. ARTs induce ferroptosis in tumor cells, although the involvement of ferroptosis in malaria remains unclear. We found that three typical inducers of ferroptosis (erastin, RSL3 and sorafenib) could effectively mimic DHA inhibition on the growth of blood-stage parasites, which exhibited synergistic or nearly additive interactions in vitro with DHA, while the combination of DHA with ferroptosis inhibitors (deferoxamine, liproxstatin-1) had an obvious antagonistic effect. DHA, similar to ferroptosis inducers, can simultaneously induce the accumulation of ferroptosis-associated cellular labile iron and lipid peroxide. However, deferoxamine and liproxstatin-1 reduced the increase in ferrous iron and lipid peroxide caused by DHA. These results suggested that ferroptosis might be an effective way to induce cell death in parasites and could be a primary mechanism by which DHA kills parasites, with almost 50% contribution at low concentrations. These results provide a new strategy for antimalarial drug screening and clinical medication guidance.

Abstract
Objective: To evaluate the clinical value of aspirin as a prophylactic for transplant renal artery stenosis (TRAS). Methods: From January 2017 to November 2019, clinical data of 307 patients who had undergone renal transplant in Zhengzhou University People's Hospital were collected. Patients were divided into two groups: the treatment group (124 recipients who had taken oral aspirin 100 mg/d after transplant) and the control group (183 recipients who had not taken aspirin after transplant). The general data, incidence of initially diagnosed and confirmed TRAS, type of renal artery anastomosis vessels, duration of stenosis, location of stenosis, and complications were compared between the two groups. The treatment group was further divided into two subgroups, the early group (92 recipients) and the delayed group (32 recipients), according to the time of starting aspirin after operation. Subgroup analysis was performed. Results: Among all 307 patients included, there were 241 males and 66 females, aged 19-64 years. There were no statistical difference between the treatment and control groups in terms of gender, age, comorbidities, number of arterial vessels, type of graft, and acute rejection all P>0.05. Among 46 initially diagnosed TRAS patients, 13 (10.5%) and 33 (18.0%) cases were in the treatment and control group respectively, with no statistically significant difference in stenosis rate (P>0.05). The number of confirmed TRAS patients was 1 (0.8%) and 24 (13.1%) in the treatment and control group respectively, with statistically significant difference in stenosis rate (P<0.001). The proportion of patients with bleeding disorders in the treatment group was slightly higher than that in the control group (13.7% vs 8.7%), and the proportion of infarct diseases was slightly lower than that in the control group (1.6% vs 4.9%). But there was no significant difference in aspirin-related complications between the two groups (P>0.05). Subgroup analysis showed that there was no significant difference in initially diagnosed and confirmed TRAS and aspirin-related complications between the early group and the delayed group (all P>0.05). Conclusions: Oral low-dose aspirin after kidney transplantation can effectively reduce the incidence of TRAS, without increasing the risk of aspirin-related complications.

Abstract
Quality-of-life improvements have resulted in increasing attention being paid to research on antiaging and antioxidation. Polyphenols are natural antioxidants with excellent biological activities, such as antioxidation and scavenging of free radicals and antiviral activity. Abundant availability and low toxicity of polyphenols have attracted the attention of researchers. In this paper, the antioxidant activities of flavonoids, phenolic acids, stilbenes and lignan polyphenols are analyzed, the corresponding antioxidant mechanisms are investigated, and the antioxidant effects of polyphenols are systematically reviewed. Thus, an effective reference based on the recent literature is compiled for the study of the antioxidant mechanisms of polyphenols that provides a significant theoretical basis for the development of products that are components of polyphenols.

Abstract
The RNA-binding protein tristetraprolin (TTP) is an anti-inflammatory factor that prompts the mRNA decay of target mRNAs and is involved in inflammatory diseases such as rheumatoid arthritis (RA). TTP is regulated by phosphorylation, and protein phosphatase 2A (PP2A) can dephosphorylate TTP to activate its mRNA-degrading function. Some small molecules can enhance PP2A activation. Short interfering RNA (siRNA) targeting TTP expression or PP2A agonist (Arctigenin) was administered to monosodium urate (MSU) crystal-induced J774A.1 cells, and the expression of inflammatory related genes was detected by RT-PCR and Western blot assays. The effects of Arctigenin in mouse models of acute inflammation induced by MSU crystals, including peritonitis and arthritis, were evaluated. The data indicated that TTP expression levels and endogenous PP2A activity were increased in MSU-crystal treated J774A.1 cells. TTP knockdown exacerbated inflammation-related genes expression and NLRP3 inflammasome activation. However, PP2A agonist treatment (Arctigenin) suppressed MSU crystal-induced inflammation in J774A.1 cells. Arctigenin also relieved mitochondrial reactive oxygen species (mtROS) production and improved lysosomal membrane permeability in MSU crystal-treated J774A.1 cells. Moreover, TTP knockdown reversed the anti-inflammatory and antioxidant effects of Arctigenin. Oral administration of Arctigenin significantly alleviated foot pad swelling, the number of inflammatory cells in peritoneal lavage fluids and the production of IL-1β in the mouse model of inflammation induced by MSU crystals. Collectively, these data imply that targeting TTP expression or functional activity may provide a potential therapeutic strategy for inflammation caused by MSU crystals.

Abstract
Abstract
Although prostate cancer patients initially respond to androgen deprivation therapy, they eventually progress to lethal castration resistant prostate cancer (CRPC), characterized by restoration of the androgen receptor (AR) signaling despite castrate levels of circulating androgens. Mechanisms proposed to underlie CRPC include AR crosstalk with alternative signaling pathways. Among these, the Sonic hedgehog (SHH)Hedgehog (HH) pathway, an essential signaling axis in prostate development and homeostasis, has been implicated in prostate cancerCRPC progression. SHH pathway is regulated by transcription factors and effectors Glioma-associated oncogene family zinc finger (GLI) proteins 1, 2, and 3. Previous studies reported that GLI1 and GLI2 drive androgen-independent growth of prostate cancer by upregulating androgen-stimulated genes. However, whether and how GLI3 plays a role in prostate cancer progression remains unclear. In the present study, we investigated the role of GLI3 in the progression of prostate cancer cells. Like GLI2, GLI3 is the a downstream transcriptional factor effector of the SHH signaling pathway that can exist as a full-length activator form or a cleaved repressor form. Our data showed an increase in GLI3 expression in prostate cancer cells growing under androgen deprived conditions. Thuserefore, we hypothesize that androgen deprivation leads to activation of the SHH signaling pathway which consequently activates GLI3 to promote androgen-independent growth of prostate cancer cells. We showed that knockdown of GLI3 repressed while overexpression of GLI3 promoted androgen-independent growth of prostate cancer cells. GLI3 knockdown also resulted in regression of castration-resistant outgrowth of xenograft tumors in mice. Additionally, transcriptomic analysis of GLI3 knockdown cells revealed that the SHH signaling pathway and epithelial mesenchymal transition (EMT) genes are altered suggesting that GLI3 regulates androgen-independent growth of prostate cancer cells through canonical SHH signaling pathway and likely contributes to prostate cancer metastasis. Lastly, our data demonstrated a physical and functional relationship between GLI3 and AR suggesting a functional crosstalk between SHH signaling and AR signaling pathways in advanced prostate cancer.

Abstract
Selenium is a trace element necessary for the growth of organisms. Moreover, selenium supplementation can improve the immunity and fertility of the body, as well as its ability to resist oxidation, tumors, heavy metals, and pathogenic microorganisms. However, owing to the duality of selenium, excessive selenium supplementation can cause certain toxic effects on the growth and development of the body and may even result in death in severe cases. At present, increasing attention is being paid to the development and utilization of selenium as a micronutrient, but its potential toxicity tends to be neglected. This study systematically reviews recent research on the toxicological effects of selenium, aiming to provide theoretical references for selenium toxicology-related research and theoretical support for the development of selenium-containing drugs, selenium-enriched dietary supplements, and selenium-enriched foods.

Abstract
Many studies in modern times claim that the name " 100-day cough" is from traditional Chinese medicine, and even think that there is a description of pertussis as early as the Sui Dynasty classics. By reviewing the original texts of the classics, we found that these interpretations are not exactly. The description of the pertussis and the chronological distribution of the literature in traditional Chinese books are similar to those of Western medicine. They started about 500 years ago, and then become more detailed and specific. The domestic medical community has a variety of nomenclature for this disease, and there is no sign or evidence to uniformly use "100-day cough" as the disease name. The literature records suggest that "100-day cough" first became a more recognized disease name in Japan, and through the direct input of medical education, entered the modern medical textbooks of western medicine in China.

Abstract
Objective: To examine the clinical treatment methods and short- and mid-term results of traumatic aortic injury (TAI). Methods: The clinical data of 30 patients suffering from TAI who were admitted to Department of Cardiothoracic Surgery, General Hospital of Eastern Theater Command from January 2010 to December 2018 were summarized and analyzed retrospectively. All patients were diagnosed as TAI by aortic CT angiography. There were 20 males and 10 females, aging (46.4±15.2) years (range: 17 to 76 years). One patient was diagnosed as extensive intramural hematoma (IMH). The other 29 cases had aortic intimal injury, and the primary intimal tear of all these patients was located in the isthmus of descending aorta. There were 2 cases of ulcer-like changes combined with IMH, and 27 cases of traumatic aortic dissection (TAD) including 23 cases of localized TAD and 4 cases of extensive TAD. Endovascular repair, artificial vascular replacement or conservative treatment were performed according to the patient's specific condition. The patients were followed up in outpatient or by telephone. The clinical data of all the patients of the in-hospital treatment and during follow-up period was analyzed retrospectively. Results: One patient with IMH was treated conservatively. Surgical intervention was performed in 29 cases with intimal injury, of which 14 cases underwent emergency surgery on the day of admission or the next day, and 15 cases underwent elective surgery. Twenty-seven cases underwent thoracic endovascular aortic repair (TEVAR), and 2 cases underwent artificial vascular replacement. Nine cases suffered combined operations in early or late stage. All patients were cured and discharged with in-hospital stay of (13.2±5.4) days (range: 7 to 30 days). There was no in-hospital death. Two patients underwent tracheotomy, and the rest had no serious complications. Up to the last follow-up in June 2019, 4 patients were lost to follow-up, and the remaining 26 patients were followed up for (50.6±34.1) months (range: 6 to 112 months) and survived healthily without new aortic events. Conclusions: Most of TAD cases are ascribed to Stanford type B aortic dissection, and a satisfactory short-term and mid-term result can be achieved by emergency TEVAR in most patients. Some patients can achieve good long-term results by open surgery with artificial vascular replacement.

Abstract
The development of high-efficiency and stable electrocatalysts is significant for energy conversion and storage. The oxygen evolution reaction (OER), a pivotal half reaction, is seriously limited in its practical applications due to its sluggish kinetics and thus an excellent electrocatalyst for OER is urgently required. In this paper, we design a novel Co3O4 nanomesh (Co3O4 NMs) with high density grain boundaries (GBs), which functions as a highly efficient and steady OER electrocatalyst. The optimal Co3O4 NMs-500 can achieve a low overpotential of 295 mV at a current density of 10 mA cm-2, and a small Tafel slope of 31 mV dec-1, which exceeds the commercial Ir/C, as well as the majority of other catalysts reported in the literature. The Co3O4 NMs-500 also exhibit promising durability, with a negligible decline in activity after 18 h of operation. Detailed studies indicate that the presence of GBs leads to more exposed active sites and the enhanced adsorption of intermediate species on Co3O4 NMs-500, thereby improving the OER's catalytic activity. This work not only relates to the activity-GBs relationship, but also opens up a unique perspective for the design of the next generation of electrocatalysts.

Abstract
Education in people's early lives are positively related to their cognitive function, but its modulating effects on detailed cognition domains, its interaction with leisure activities and the associated brain changes have yet to be investigated. This report used data from 659 cognitively normal community dwelling elderly who completed neuropsychological tests, leisure activities measurement, and 78 of them underwent structural and diffusion MRI scans. We found that: (i) the highly educated elderly had a better cognitive functioning in multi-domains, higher frequencies of participation in knowledge-related leisure activities, and slower age-related reductions of executive function; (ii) the intellectual and social types of leisure activities mediated the association between education and multiple cognitive domains, including memory, language, attention and executive function; (iii) there was a significant age by education interaction on the gray matter volume of the anterior brain regions and white matter integrity; and (iv) the interaction between age and education affected cognition indirectly through white matter integrity analyzed using structural equation model. Overall, our results revealed that high education in early life served as a protective factor in aging that may help to postpone cognitive and brain reserve decline in cognitively normal aging.

Abstract
Objective: To investigate the characteristics and prognostic value of peripheral blood T lymphocyte subsets in patients with severe influenza. Methods: This was a single-center cross-sectional study in influenza patients admitted to Peking Union Medical College Hospital from August 2017 to April 2018. Peripheral blood lymphocyte subsets were detected by flow cytometry in both patients and 108 healthy controls. Influenza patients were divided into mild group and severe group. Severe patients were further classified into alive and fatal subgroups. Results: A total of 42 influenza patients were recruited in this study, including 24 severe cases (6 deaths). The remaining 18 cases were mild. The peripheral blood lymphocyte counts and lymphocyte subset counts (B, NK, CD4(+)T, CD8(+)T) in either mild patients[795 (571,1 007), 43 (23,144), 70 (47,135), 330 (256,457), 226 (148,366) cells/μl respectively] or severe patients[661 (474,1 151),92 (52,139), 54 (34,134), 373 (235,555), 180 (105,310) cells/μl respectively] were both significantly lower than those of healthy controls [1 963 (1 603,2 394),179 (119,239), 356 (231,496), 663 (531,824), 481 (341,693) cells/μl respectively]. Meanwhile, the T cells and CD8(+)T counts in fatal patients [370 (260,537) cells/μl and 87 (74,105) cells/μl] were significantly lower than those in severe and alive patients [722 (390,990) cells/μl and 222 (154,404) cells/μl]. CD8(+)HLA-DR/CD8(+)and CD8(+)CD38(+)/CD8(+)T cell activating subgroups in mild cases[(53.7±19.2)% and 74.8% (64.1%,83.7%) respectively] were significantly higher than those in severe cases[(38.5±21.7)% and 53.3% (45.3%,67.2%) respectively].Moreover,CD8(+)HLA-DR/CD8(+)count in severe and alive group was higher than that in fatal group [(46.1±19.1)% vs. (18.2±14.6)%, P<0.01]. Logistic regression analysis showed that CD8(+)T cell count (OR=0.952, 95%CI 0.910-0.997, P=0.035) and CD8(+)HLA-DR/CD8(+)T (OR=0.916, 95%CI 0.850-0.987, P=0.022) were both negatively correlated with mortality.Peripheral blood lymphocyte counts in mild cases rapidly decreased within 1 day after diagnosis, and returned to the basic level one week later. Conclusions: All peripheral blood lymphocyte subsets (T,B,NK) in patients with influenza are significantly reduced. These findings are consistent with the immunological characteristics of respiratory viral infections, in which peripheral lymphocytes (especially T cells) migrate to respiratory tract in the early stage and circulate to the peripheral blood after recovery. The activated CD8(+)T cell counts in peripheral blood are negatively correlated with the severity of disease, which could be considered as a prognostic indicator of severe influenza.

Abstract
BACKGROUND Among the protective factors for cognitive decline related to aging and Alzheimer's disease, education level is one of the most prominent. However, the mechanisms underlying the protective effects of education on cognition remain to be elucidated. In this study, we aimed to systematically assess the role of Functional Connectivity (FC) of resting-state brain networks playing in the cognition-protection effect of education. METHODS Data from a battery of neuropsychological tests and functional magnetic resonance imaging in resting-state were acquired in 77 cognitively normal elderly participants from local communities in Beijing, China. Six resting-state networks related to primary function or complex cognition were extracted through independent component analysis. We then explored the relationships between education level, cognition, and FC of these networks. RESULTS We found that education level was positively associated with a wide range of complex cognitive domains including general mental status, episodic memory, language, attention, executive function and visuospatial processing, and it showed significantly negative correlations with FC of multiple areas in the Default Mode Network (DMN) and Left Frontal-parietal Network (LFP) which are related to complex cognition. And regional connectivity of DMN was significantly negatively correlated with episodic memory performance. Further mediation analysis suggested that higher education level was associated with higher episodic memory performance through lower regional connectivity of DMN. CONCLUSION Our findings indicate that inhibitory modulation in the resting-state brain networks related to complex cognition is one of the main routes through which education exerts its protective effects on cognition in normal aging.

Abstract
Tooth brushing is necessary to maintain oral health. Little research has been carried out to explore microbial diversity in toothbrushes and to study the potential impact of these bacteria on human health. In the present study, 20 participants were enrolled, and the microbial diversity in their oral cavity and toothbrushes was investigated using high-throughput sequencing. Our results indicate that 1,136 and 976 operational taxonomic units (OTUs) were obtained from groups CB (samples from toothbrushes of participants using traditional Chinese medicinal toothpaste) and AB (samples from toothbrushes of those using antibacterial toothpaste), respectively. The pathogens Acinetobacter baumannii, Staphylococcus aureus, and Candida albicans were identified on toothbrushes. The presence of these pathogens increases the chance for the host to get infectious diseases, neurodegenerative diseases, cardiovascular diseases, and cancers. Moreover, our in vitro results indicate that traditional Chinese medicinal toothpaste and antibacterial toothpaste can not only inhibit the growth of pathogens but also markedly inhibit the growth of probiotics Lactobacillus salivarius and Streptococcus salivarius. Therefore, the inhibitory effect of toothpaste on probiotics, together with the existence of pathogens in toothbrushes, indicates a potential risk of tooth brushing for people in a sub-healthy state.

Abstract
OBJECTIVE To investigate the effects of hyperkalemia on the brain after I/R in h transient middle cerebral artery occlusion (tMCAO) model. MATERIALS AND METHODS A total of 120 adult male SD rats were randomly assigned to four groups: (1) hyperkalemia 80 µg/g (HK80) group; (2) hyperkalemia 40 µg/g (HK40) group; (3) normal saline (NS) group; (4) sham (SH) group. The concentration of serum K+ was elevated in HK80 and HK40 groups. The transient middle cerebral artery occlusion (tMCAO) model was used to assess the effect of hyperkalemia on the brain after I/R. After 24 h reperfusion, the infarct volume and cell damage of rat's I/R brain tissue sections were analyzed. The concentration of K+, Ca2+ and calmodulin (CaM), the activity of Ca-ATPase, the expression of Western blot of Ca2+/calmodulin-dependent protein kinase II (CaMKII) and Na+/Ca2+ exchanger 1 (NCX1), were also measured. RESULTS After 24 h reperfusion, compared with NS group, the two-hyperkalemia groups (HK80 and HK40) were with less infarct volume and cell damage, higher concentration of K+ but lower Ca2+ and CaM compared with NS group. The activity of Ca-ATPase was also elevated, the expression of CaMK II and NCX1 were down-regulated in the two hyperkalemia groups. CONCLUSIONS Hyperkalemia could also ameliorate the brain I/R injury by alleviating calcium overload inhibiting the activity of NCX1, lowering the concentration of Ca2+.

Abstract
BACKGROUND Hb I and Hb Shaare Zedek are rare hemoglobin variants in the Chinese population. High-performance liquid chromatography (HPLC) is a widely used technique for screening of thalassemias and hemoglobin variants in Chinese primary hospitals. However, some rare hemoglobin variants cannot be effectively separated by HPLC. Here, we report one case of Hb I and one case of Hb Shaare Zedek which could not be detected by HPLC but required capillary electrophoresis (CE) in our hospital. METHODS Two blood samples with high Hb F level were analyzed by HPLC as part of routine screening, and then globin genes were analyzed using Gap-PCR, PCR-Reverse dot-blot (RDB), and DNA sequencing. Subsequently, samples were analyzed by CE and results compared to HPLC. RESULTS In case 1, results were as follows: Hb F 16.9%, Hb A0 72.5% (failed to show the value of Hb A in HPLC) and Hb A2 2.2% for HPLC. No mutations were detected using Gap-PCR and PCR-RDB, but there was a mutation of codon (CD) 16 in the α2 globin gene (AAG>GAG, corresponds to Hb I) by DNA sequencing. CE showed Hb A2 1.9%, Hb A 74%, Hb I 24.1%. In case 2, results were as follows: Hb F 11.0%, Hb A0 76.6%, and Hb A2 4.7% for HPLC. It showed a CD 41 - 42 mutation of the β-globin gene (-TTCT) using PCR-RDB and the CD 56 mutation in α2/α1 globin gene (AAG>GAG, corresponding to Hb Shaare Zedek) with DNA sequencing. CE displayed Hb A2 4.5%, Hb A 84.6%, Hb F 0.4%, Hb Shaare Zedek 10.5%. CONCLUSIONS Hb I and Hb Shaare Zedek cannot be separated by HPLC because of co-elution with Hb F. However, they were identified and quantified using CE. As a general precaution, therefore, and owing to the existence of rare variants that may co-elute with normal hemoglobin fractions, it is recommended to use at least two complementary methods for the diagnostic detection of hemoglobin species.

Abstract
Delicate architecture of active material enables improving the performacne of lithium ion batteries. Environmental-friendly Fe2 O3 anode has high theoretical specific capacity (1007 mAh g-1 ) in lithium ion batteries, but suffers from structural collapsing and poor electronic conductivity. Herein, we design an unique hierarchical iron oxide by regulating the initial precursor prussian blue and targeting hollow-shell structures with full consideration of temperature controls. Among them, Fe2 O3 with a sheet-crossing structure at 650°C, affords obvious advantages of improved electronic conductivity, short ionic diffusion length, prevented particle agglomeration, and buffer volume change. Thus, we achieve a superior discharge specific capacity of 611 mAh g-1 at 500 mA g-1 . Regulating hierarchical structure of prussian blue-assisted oxides enables effectively enchancing Li storge performance. LAY DESCRIPTION: Nanoparticle self-assembly, one of bottom-up methods is often used to prepare hollow hierarchical structures, whereas it suffers from low productivity and insufficient stability. Hence, we designed a unique hierarchical iron oxide by top-down method with regulating the initial precursor PB and targeting hollow-shell structures through full consideration of temperature controls. Delicate architecture of active material enables improving the performacne of lithium ion batteries. Environmental-friendly Fe2 O3 anode has high theoretical specific capacity (1007 mAh g-1 ) in lithium ion batteries, but suffers from structural collapsing and poor electronic conductivity. Hence, we prepared Prussian Blue (PB) materials with different sizes and calcined them at different temperatures. We found that no matter what the size of PB, the sheet-crossing morphology appeared at 650°C, and the interlaced morphology was the key to improve the performance of lithium batteries. If the size of PB precursor is too large or too small, it has adverse effects on lithium batteries. Only when the size and calcination temperature of PB precursor reach the optimum state, the best performance can be obtained. The calcination PB-K-3 at 650°C has a unique hierarchical structure of sheet-crossing. An obvious advantages include the prevention of particle agglomeration, short ionic diffusion lengths, and buffering volume changes. As a consequence, 611 mAh g-1 was obtained at the current density of 500 mA g-1 . In addition, we observed the structural changes of electrode plates at different reaction potentials, according to the reaction equation of Fe2 O3 +xLi+ +xe→Lix Fe2 O3 . With the proceeding charge process, the voltage increases from 0.01 to 3 V, the lithium ions gradually comes out of the iron oxide electrode surface. Whereas the discharging process reverses the aforementioned phenomena. Even if the changing volumes, however, the shape of cubic blocks for the PB-K-3 is preserved at different potentials. Taking these advantages into account, our designed MOFs-derived struture was an effective way to prepare hollow hierarchical structure with enhanced Li storage performacne. Such work is expected to facilitate the design of new electrode structure of lithium batteries.
