Abstract
Objective Escherichia coli is a common Gram-negative human pathogen. The emergence of E. coli with multiple-antibiotic-resistant phenotypes has become a serious health concern. This study reports the whole-genome sequences of third-generation cephalosporin-resistant (3GC-R) and multidrug-resistant (MDR) E. coli EC6868 and explores the acquired antibiotic-resistance genes (ARGs) as well as their genetic contexts. Methods E. coli EC6868 was isolated from a vaginal secretion sample of a pregnant patient in China. The antimicrobial susceptibility was assessed, and whole-genome sequencing was conducted. The acquired ARGs, insertion sequence (IS) elements, and integrons within the genome of E. coli EC6868 were identified, and the genetic contexts associated with the ARGs were analyzed systematically. Results E. coli EC6868 was determined to belong to ST69 and harbored a 144.9-kb IncF plasmid (pEC6868-1) with three replicons (Col156, IncFIBAP001918, and IncFII). The ESBL gene blaCTX-M-27 was located on the structure "∆ISEcp1-blaCTX-M-27-IS903B", which was widely present in the species of Enterobacteriales. Other ARGs carried by plasmid pEC6868-1 were mainly located on the 18.9-kb IS26-composite transposon (five copies of intact IS26 and one copy of truncated IS26) composing of IS26-mphA-mrx(A)-mphR(A)-IS6100, ∆TnAs3-eamA-tet(A)-tetR(A)-aph(6)-Id-aph(3")-Ib-sul2-IS26, and a class 1 integron, which was widely present on IncF plasmids of E. coli, mainly distributed in ST131, ST38, and ST405. Notably, pEC6868 in our study was the first report on a plasmid harboring the 18.9-kb structure in E. coli ST69 in China. Conclusion The 3GC-R E. coli ST69 strain with an MDR IncF plasmid carrying blaCTX-M-27 and other ARGs, conferring resistance to aminoglycosides, macrolides, sulfonamides, tetracycline, and trimethoprim, was identified in a hospital in China. Mobile genetic elements including ISEcp1, IS903B, IS26, Tn3, IS6100 and class 1 integron were found within the MDR region, which could play important roles in the global dissemination of these resistance genes.

Abstract
Okadaic acid (OA) is one of the most prevalent marine phycotoxin with complex toxicity, which can lead to toxic symptoms such as diarrhea, vomiting, nausea, abdominal pain, and gastrointestinal discomfort. Studies have shown that the main affected tissue of OA is digestive tract. However, its toxic mechanism is not yet fully understood. In this study, we investigated the changes that occurred in the epithelial microenvironment following OA exposure, including the epithelial barrier and gut bacteria. We found that impaired epithelial cell junctions, mucus layer destruction, cytoskeletal remodeling, and increased bacterial invasion occurred in colon of rats after OA exposure. At the same time, the gut bacteria decreased in the abundance of beneficial bacteria and increased in the abundance of pathogenic bacteria, and there was a significant negative correlation between the abundance of pathogenic bacteria represented by Escherichia/Shigella and animal body weight. Metagenomic analysis inferred that Escherichia coli and Shigella spp. in Escherichia/Shigella may be involved in the process of cytoskeletal remodeling and mucosal layer damage caused by OA. Although more evidence is needed, our results suggest that opportunistic pathogens may be involved in the complex toxicity of OA during OA-induced epithelial barrier damage.

Abstract
Microcystin-leucine arginine (MCLR) is a phycotoxin produced by cyanobacteria. As a hepatotoxin, increasing evidence suggests that it has some negative effects on the mammal gastrointestinal tract, but further studies are warranted. In this study, we investigated the effects of MCLR on the intestinal epithelial microenvironment by oral administration of MCLR. As expected, MCLR at doses of 200 and 400 μg kg-1 bw showed hepatorenal toxicity in rats but without significant gastrointestinal symptoms. MCLR exposure decreased the thickness of the colonic epithelial mucus layer, and down-regulated the expression of main mucin protein (MUC2), cytoskeletal assembly-related genes (Arpc1a, Enah) and cytoskeletal stability-related genes (Ptk2, Prkca, Actn1, Pxn, Tln1, Cttn, Vcl) in colonic tissue to varying degrees, but did not affect the expression of cell connection-related genes including Zo1, Ocln, Cldn2 and Cdh1. In addition, MCLR exposure had a limited effect on gut bacterial diversity but clearly enriched specific bacteria. Prevotella, which plays a crucial role in balancing health and disease, was inhibited, whereas Muribaculaceae concerning the epithelial barrier, was promoted. Together, our findings demonstrate that MCLR exposure can weaken the colonic epithelial barrier by interfering with the stability of the cytoskeleton, which in turn exacerbates the homeostasis maintenance in the intestinal microenvironment.

Abstract
RATIONALE Salvianolic acid B (Sal B), the Q-marker in Salvia miltiorrhiza, was proved to present an obvious anti-diabetes effect when treated as a food intake. Until now, the metabolism feature, tissue distribution and anti-diabetes mechanism of Sal B have not been fully elucidated. METHODS The metabolites of Sal B in rats were profiled using ultrahigh-performance liquid chromatography coupled with time-of-flight mass spectrometry. The potential anti-diabetes mechanism of Sal B was predicted by network pharmacology. RESULTS A total of 31 metabolites were characterized in rats after ingestion of Sal B at a dosage of 40 mg/kg, including 1 in plasma, 19 in urine, 31 in feces, 0 in heart, 0 in liver, 0 in spleen, 1 in lung, 1 in kidney and 0 in brain. Among them, 18 metabolites were reported for the first time. Phase I reactions of hydrolysis, hydrogenation, dehydroxylation, hydroxylation, decarboxylation and isomerization, and phase II reactions of methylation were found in Sal B. Notably, decarboxylation and dehydroxylation were revealed in Sal B for the first time. The pharmacology network results showed that Sal B and its metabolites could regulate ALB, PLG, ACE, CASP3, MMP9, MMP2, MTOR, etc. The above targets were involved in insulin signaling pathway, PI3K-Akt signaling pathway, HIF-1 signaling pathway, TNF signaling pathway, etc. CONCLUSIONS: The metabolism feature of Sal B in vivo was systematically revealed, and its anti-diabetes mechanism for further pharmacological validations was predicted based on metabolite profiling and network pharmacology for the first time.

Abstract
RATIONALE Characterizing the functional mechanism of quality control marker (Q-marker) was of great importance in revealing the primary pharmacological mechanism of herbs or the other complex system, and drug-related metabolites always contribute to the pharmacological functions. Cortex Phellodendri was used as a core herb in the treatment of diabetes mellitus (DM). As a Q-marker of Cortex Phellodendri, the role of phellodendrine in DM was still unclear. Thus, the characterization of phellodendrine-related metabolites in vivo and the subsequent induced functional mechanism exerted great importance in elucidating the anti-DM mechanism of Cortex Phellodendri. METHODS An ultra-high-performance liquid chromatography-coupled time-of-flight mass spectrometry (UHPLC/Q-TOF MS) method was developed to profile metabolites of phellodendrine in rats. The potential pharmacological mechanism against DM was predicted by network pharmacology. RESULTS A total of 19 phellodendrine-related metabolites were screened out in rats for the first time. Among them, M4, M5, M9, and M12 were regarded as the primary metabolites. Meanwhile, phase I metabolic reactions of hydroxylation, demethylation, and isomerization and phase II reactions of glucuronidation and sulfation occurred to phellodendrine; glucuronidation and hydroxylation were the two main metabolic reactions. Moreover, the potential targets of phellodendrine and three main metabolites (M4, M5, and M12) were predicted by a network pharmacological method, and they mainly shared 52 targets, including PDE5A, CHRNA3, SIGMAR1, F3, ESR1, DRD1, DRD2, DRD3, and DRD4. Furthermore, Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that calcium signaling pathway, cGMP-PKG signaling pathway, and cAMP signaling pathway were regarded as the core mechanism of phellodendrine to treat DM. CONCLUSION The metabolic feature of phellodendrine in vivo was revealed for the first time, and its anti-DM mechanism information for further pharmacological validations was also supplied. It also gave a direction to further elucidation of pharmacological mechanism of Cortex Phellodendri in treating DM.

Abstract
In late December 2019, the COVID-19 pandemic caused a great threat to people's lives worldwide. As a special category of the population, pregnant women are vulnerable during emergencies. This study was designed to explore whether or not the COVID-19 pandemic has influenced maternal and infant outcomes. We collected maternal characteristics, laboratory results, condition in the third trimester, maternal outcome, fetal or neonatal outcomes, and characteristics of amniotic fluid, umbilical cord and placenta from pregnant women and fetals or newborns in the first affiliated hospital of Jinan university from 24 January to 31 March 2020 (peak period), chose the same types of data at the hospital during the same period in 2019 and 1 January-23 January 2020 (prior to the outbreak of COVID-19 in 2020) as a control. Our study focused on uncomplicated singleton pregnancies among women not infected by COVID-19. The results demonstrated that there was not an increase in adverse outcomes of pregnant women and newborns during the COVID-19 pandemic; This might be associated with the updated design of major epidemic prevention and control systems in Guangzhou, and the extension of pregnant women's rest time during the third trimester of pregnancy. Nevertheless, the survey showed an increased incidence rate of 25-hydroxyvitamin D and zinc deficiency in newborns during the epidemic, implying that pregnant women should participate in appropriate physical exercise, increase their exposure to outdoor sunlight and improve nutrition intake to ensure healthy newborns during the quarantine period. Our study has provided some guidance for maternal management during the COVID-19 pandemic.

Abstract
Food additives are widely used in our daily life, and the side-effects caused by them have gained extensive attention around the world. Notably, constituent-oriented metabolites, in some sense, always contribute to pharmacological changes, inducing toxicity, therapeutic effects, etc. Characterization of the metabolites and their potential functions is of great importance to the practical applications. In this work, an integrated strategy by combining metabolite profiling and network pharmacology was applied to characterize the metabolic features and reveal pharmacological changes of neohesperidin dihydrochalcone (NHDC) in vivo to demonstrate its pharmacological mechanism and potential functions. As a result, a total of 19 metabolites (3 in plasma, 19 in urine, 8 in feces, 3 in heart, 5 in liver, 0 in spleen, 1 in lung, 2 in kidneys and 2 in brain) were screened and 18 of them were characterized for the first time. Phase I metabolic reactions of hydrolysis and phase II reactions of glucuronidation, sulfation, glutamylation, N-butyryl glycylation and lactylation were the main metabolic reactions of NHDC in vivo. Moreover, the results analyzed by network pharmacology revealed that, in addition to common pathways (steroid hormone biosynthesis) of NHDC, metabolites' targets were involved in pathways in cancer, ovarian steroidogenesis, proteoglycans in cancer, PI3K-Akt signaling pathway and progesterone-mediated oocyte maturation, indicating that these functional changes might result in potential novel functions or other side-effects, such as a disorder of steroid hormones. Our work provided the metabolic features and functional modifications of NHDC in vivo for the first time, and meaningful information for further pharmacological validations or potential functions is supplied.

Abstract
OBJECTIVE We present the prenatal diagnosis of a class II 1q21.1 microdeletion in monozygotic (MZ) twins with discordant phenotypes. CASE REPORT A monochorionic diamniotic twin pair presented with discordant ultrasound anomalies; twin A had cardiovascular abnormalities, while twin B did not. No specific complications were noted in the twins during pregnancy. A single nucleotide polymorphism array revealed an identical class II 1q21.1 microdeletion inherited from a phenotypically normal mother and identified the twins as MZ. The deleted region encompassed both the proximal 1q21.1 thrombocytopenia absent radius syndrome region and the distal 1q21.1 recurrent microdeletion region. No other rare copy number variants (CNVs) were identified, and concordance was observed in the CNVs between the twins. CONCLUSION Discordant cardiovascular abnormalities may occur in MZ twins carrying the same class II 1q21.1 microdeletion. Further studies involving discordant MZ twins are needed to determine the modifying factors of the phenotypic heterogeneity of the microdeletion.

Abstract
Lonicerae japonicae flos.(LJF) was widely used as a drug to treat upper respiratory tract infection or a tea to clear heat in Asian countries for thousands of years. Despite of its curative effects confirmed by modern pharmacological methods, its functional materials and mechanism against influenza were still unclear and needed further investigation. In this study, an integrated strategy based on in vivo substances profiling and network pharmacology was proposed and applied to screen out the potential anti-influenza substances and mechanism of LJF. An UHPLC/Q-TOF MS method was utilized to profile the chemical components in LJF and their metabolites in rats. The targets of absorbed prototypes were predicted by Swiss Target Prediction, and they were further analyzed by String and Kyoto Encyclopedia of Genes and Genomes (KEGG). As a result, a total of 126 chemical components mainly featuring three chemical structure types were characterized, including 70 iridoid glycosides, 17 caffeoylquinic acids, 24 flavonoids, and 15 other types compounds. Among them, ten N-contained iridoid glycosides were characterized as potential novel compounds. Moreover, 141 xenobiotics (74 prototypes and 67 metabolites) were clearly screened out in rat plasma and urine after ingestion of LJF. Phase II reactions (sulfation, glucuronidation, methylation) and phase I reactions (dehydroxylation, hydrogenation, hydrolysis, N-heterocyclization) were the main metabolic reactions of LJF in rats. Further, a total of 338 targets were predicted and TNF, PTGS2 and EGFR were the three main targets involved in the pathology of influenza. In addition to normal NF-κB pathway, T cell signal pathway and mTOR signal pathway were the other patterns for LJF to achieve its anti-flu effects. Our work provided the meaningful data for further pharmacological validation of LJF against influenza, and a new strategy was also proposed for minimizing the process to reveal the mechanism and functional basis of TCMs.

Abstract
Traditional Chinese medicine was widely used in China since its definite effects and therapy. The components of TCM were absorbed into the circle system as the format of prototypes or metabolites, which contributed to the therapy or side effects. Declaring the functional changes in this process was of great importance to the clinical applications. In this work, an integrated strategy based on metabolites' profiling and network pharmacology was proposed for exploring the pharmacological changes of compounds in vivo. Arctiin, the main component in Fructus Arctii with various kinds of bioactivities, was used as an example. An ultra-performance liquid chromatography coupled with time-of-flight mass spectrometry and metabolynx™software was applied to characterize the metabolites of arctiin in rats at a dosage of 100 mg/kg; network pharmacology was applied to characterize the functional changes. As a result, fifty-three metabolites (32 in plasma, 40 in urine, 19 in bile, 20 in feces, 1 in brain, 12 in liver and 4 in lungs) were screened out and characterized, and 3 of them were unambitiously identified by comparison with standard substances. Among them, 38 metabolites were reported for the first time. It was found the major metabolic pathways of arctiin in rats were demethylation, lactone-opening and phase II conjugations with sulfate and glucuronide.It also confirmed that M14, M15, M18, M23, M22, M43 and M45 were the major circulating forms of arctiin in rats following oral administration. In addition to the above metabolic reactions, phase I reactions of hydrolysis, demethylation, dehydroxylation were also observed, and dehydrogenation were first revealed metabolic patterns of arctiin in rats. Meanwhile, in addition to the main targets of arctiin (MTOR, EGFR and MAPK14), its metabolites targeted additional 392 targets with additional functions of anti-hepatitis B or viral carcinogenesis (SRC, CAPS3, PIK3CA, CDK4, ESR1, MMP9 and ERBB2). The above results provided very important information for understanding the metabolism and functional changes of arctiinin vivo, and supporting data for further pharmacological evaluation. Our work also provided a newsight for elucidation of functional changes of TCMs in vivo.

Abstract
ATP acts as a canonical activator to induce NLRP3 (NOD-like receptor family, pyrin domain containing 3) inflammasome activation in macrophages, leading to caspase-1/gasdermin D (GSDMD)-mediated pyroptosis. It remains unclear whether ATP can induce pyroptosis in macrophages when the NLRP3 pathway is blocked by pathogenic infection. In this study, we used cellular models to mimic such blockade of NLRP3 activation: bone marrow-derived macrophages (BMDMs) treated with NLRP3-specific inhibitor MCC950 and RAW264.7 cells deficient in ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain) expression. The results showed that ATP treatment induced lytic cell death morphologically resembling canonical pyroptosis in both MCC950-treated BMDMs and RAW264.7 cells, but did not cause the activation of caspase-1 (by detecting caspase-1p10 and mature interleukin-1β) and cleavage of GSDMD. Instead, both apoptotic initiator (caspase-8 and -9) and executioner (caspase-3 and -7) caspases were evidently activated and gasdermin E (GSDME) was cleaved to generate its N-terminal fragment (GSDME-NT) which executes pyroptosis. The GSDME-NT production and lytic cell death induced by ATP were diminished by caspase-3 inhibitor. In BMDMs without MCC950 treatment, ATP induced the formation of ASC specks which were co-localized with caspase-8; with MCC950 treatment, however, ATP did not induced the formation of ASC specks. In RAW264.7 cells, knockdown of GSDME by small interfering RNA attenuated ATP-induced lytic cell death and HMGB1 release into culture supernatants. Collectively, our results indicate that ATP induces pyroptosis in macrophages through the caspase-3/GSDME axis when the canonical NLRP3 pathway is blocked, suggestive of an alternative mechanism for combating against pathogen evasion.

Abstract
Objective: To investigate the prevalence of physical activity and its influencing factors in rural residents in Shanxi and Chongqing. Methods: In four counties (districts) of Shanxi and Chongqing, local residents aged ≥18 who lived there for more than one year and had no plan to migrate to other areas in 2 years were surveyed through face to face questionnaire interviews to collect the information about their daily physical activity time, sedentary time, related knowledge and attitude, and others. Results: The physical inactivity rate of the residents was 14.9%, and 88.7% of residents never took daily physical activity. The average sedentary time was (3.91±2.06) hours. The results of multivariate analysis showed that education level, per capita monthly income and activity degree were the factors influencing physical inactivity. Conclusion: The proportion of people who never took daily physical activity in the survey area was higher than the average level in rural areas in China, so measures should be taken to improve the overall rate of physical activity. For people who have exercise willingness, but have no practice, and those who have already increased their physical activities, targeted guidance is needed on the basis of strengthened health education.

Abstract
The burgeoning of the life insurance industry in Taiwan cannot be attributed solely to a rise in incomes, but also to increasing urbanization and industrialization, aggressive marketing strategies introduced by U.S. life insurance companies, and important changes in values that make it increasingly acceptable to own life insurance. The growing use of life insurance can be considered part of a transition from informal, familial care of the elderly to formal market mechanisms to protect the financial security of loved ones, including a widowed spouse, and as one component of the pattern of intergenerational relations. We use data from the 1991-92 Telephone Followup to the 1989 Survey of Health and Living Status of the Elderly in Taiwan to explore the extent to which familial resources and socioeconomic/demographic characteristics influence the propensity of elderly persons to own life insurance. We also consider motivations for and against the ownership of insurance, and if insurance is currently held, the relationship of the beneficiary to the respondent. We conclude with suggestions for additional data that can help resolve a number of issues raised in this exploratory study.

Abstract
Never-married women have been regularly excluded in official national surveys of fertility in China, even in light of evidence of increasing premarital sexual activity. Likewise, never-married women in the United States were consistently excluded from national fertility surveys prior to 1982 because of the perceived sensitivity of questions about contraceptive use and sexual activities. Data on sexual and fertility behavior from all women of reproductive age, regardless of marital status, can provide direct measures of sexual activity and unintended pregnancies, as well as facilitate modeling of social networks underlying the sexual transmission of diseases. China's need for such information, however sensitive, will become more difficult to ignore given increasing pressures to attend to the health needs of their never-married but sexually active population.
