Humane orientation, work-family conflict, and positive spillover across cultures.

Although cross-national work-family research has made great strides in recent decades, knowledge accumulation on the impact of culture on the work-family interface has been hampered by a limited geographical and cultural scope that has excluded countries where cultural expectations regarding work, family, and support may differ. We advance this literature by investigating work-family relationships in a broad range of cultures, including understudied regions of the world (i.e., Sub-Saharan Africa, Southern Asia). We focus on humane orientation (HO), an overlooked cultural dimension that is however central to the study of social support and higher in those regions. We explore its moderating effect on relationships between work and family social support, work-family conflict, and work-family positive spillover. Building on the congruence and compensation perspectives of fit theory, we test alternative hypotheses on a sample of 10,307 participants from 30 countries/territories. We find HO has mostly a compensatory role in the relationships between workplace support and work-to-family conflict. Specifically, supervisor and coworker supports were most strongly and negatively related to conflict in cultures in which support is most needed (i.e., lower HO cultures). Regarding positive spillover, HO has mostly an amplifying role. Coworker (but not supervisor) support was most strongly and positively related to work-to-family positive spillover in higher HO cultures, where providing social support at work is consistent with the societal practice of providing support to one another. Likewise, instrumental (but not emotional) family support was most strongly and positively related to family-to-work positive spillover in higher HO cultures.

Application of cocrystal separation technology in the separation and purification of genistein-puerarin-daidzein ternary system / 药学学报

Cocrystal separation technology is a technology that utilizes coformers to selectively form cocrystals with target compounds and separate them from mixed systems. Our study used puerarin (PUE), daidzein (DDZ), and genistein (GEN) as model drugs, which have similar structures and are the main isoflavones in Pueraria lobata root. The separation and purification processes in the modern traditional Chinese medicine (TCM) of these three components use conventional column chromatography, recrystallization, and other technologies, which have the issues of lengthy separation cycles, high solvent consumption, and inefficient preparation. Different with existing separation technology, our team used the early-found cocrystal separation method to design a step-by-step extraction and separation experiment of GEN-PUE-DDZ ternary mixture. Caffeine and L-proline were added to the mixed system in turn, GEN-caffeine cocrystal and PUE-proline cocrystal were prepared by suspension method. The cocrystals precipitated out of the solution. The purities of the GEN-caffeine cocrystal and the PUE-proline cocrystal could achieve 93% (the purity of GEN) and 99% (the purity of PUE). Besides, the purity of DDZ could also be increased by 6.76 times. This study proposed a simple operating, low cost and wide application range separation method different from the traditional separation method and realized the separation of structurally similar chemical components in TCM, laying a foundation for the application of cocrystal technology in the separation and refining of TCM.

Objective@#To explore the effectiveness of preventive treatment for latent tuberculosis infection (LTBI) patients, so as to provide reference for the management and preventive treatment of clustered epidemic in schools.@*Methods@#Data came from the school tuberculosis outbreak of a boarding high school in Kaizhou District, Chongqing, which occurred between June 2017 and March 2018 among 2016 grade high school teachers and students for investigation and analysis. The total incidence, LTBI patients, and the incidence after preventive treatment for 5 years were followed up.@*Results@#A total of 34 cases of pulmonary tuberculosis from June 2017 to March 2018. A total of 1 357 individuals were screened for 6 concentrated contact screenings, with a confirmed tuberculosis rate of 2.43%, a tuberculosis skin test (TST) positive rate of 27.41%, and a strong TST positive rate of 7.39%. Among them, the confirmed tuberculosis rate and TST positive rate in the first case class were much higher than those in other classes, with statistically significant differences ( χ 2=286.30, 98.59, P ＜0.01). 88 cases of LTBI were found, with 31 cases receiving preventive treatment (35.23%), of which 28 completed preventive treatment (90.32%). After five years of follow-up, 73 cases of pulmonary tuberculosis were diagnosed in 2016 by the school senior high school, with a incidence rate of 0.98/10 2 (person/person years). Fifteen of the 88 LTBI patients were diagnosed with pulmonary tuberculosis, and the incidence rate was 3.33/10 2 (person/person years). The incidence rate of the preventive treatment group was 0.7/10 2 (person/person years)lower than that of the medical observation group 4.5/10 2 (person/person years), with a statistically significant difference ( χ 2=4.31, P ＜0.05).@*Conclusion@#The classes with higher TST positive rate and strong positive rate have higher incidence rate. Improving the preventive treatment rate of LTBI patients can effectively reduce the incidence rate of tuberculosis.

Mechanism of Flemiphilippinin D Regulating Inflammatory Response in CIA Rats Through TLR2/MyD88/NF-κB Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo observe the effect of Flemiphilippinin D on collagen-induced arthritis （CIA） in rats and explore its mechanism. MethodForty rats were randomly divided into normal group， CIA group， methotrexate （MTX） group （1.35 mg·kg-1）， low-dose Flemiphilippinin D group （1.5 mg·kg-1）， and high-dose Flemiphilippinin D group （3.0 mg·kg-1）， with eight rats in each group. Except for the normal group， the CIA model was induced by type Ⅱ collagen. Each group was given corresponding liquid medicine or normal saline， once a week in the MTX group， and once a day in the Flemiphilippinin D groups for a total of 28 days. The arthritis score and joint swelling degree of rats were experimentally recorded. Pathological changes in the ankle joint of rats were observed by hematoxylin-eosin （HE） staining. Serum levels of inflammatory cytokines interleukin （IL）-1β， IL-6， IL-8， and tumor necrosis factor （TNF）-α were detected by enzyme-linked immunoabsorbent assay （ELISA）， and the mRNA expression of Toll-like receptor 2 （TLR2）， myeloid differentiation factor 88 （MyD88）， and nuclear transcription factor-κB （NF-κB） p65 were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and the protein expressions of TLR2， MyD88， and NF-κB p65 were detected by Western blot. ResultCompared with the normal group， the ankle joint of the CIA group was significantly swollen， and the clinical score of arthritis and the degree of joint swelling were significantly increased （P<0.01）. The ankle joint tissue structure was significantly damaged， and the levels of inflammatory factors IL-1β， IL-6， IL-8， and TNF-α in serum were significantly increased （P<0.01）. The mRNA levels and protein levels of TLR2， MyD88， and NF-κB p65 were significantly increased（P<0.01）. Compared with the CIA group， arthritis clinical score and joint swelling of rats in each administration group were significantly reduced （P<0.05， P<0.01）， and the pathological changes in the ankle joint were significantly improved. The contents of serum IL-1β， IL-6， IL-8， and TNF-α were significantly decreased （P<0.05， P<0.01）. The mRNA levels and protein levels of TLR2， MyD88， and NF-κB p65 in the ankle joint were significantly decreased （P<0.05， P<0.01）. ConclusionTo a certain extent， Flemiphilippinin D can reduce the expression of inflammatory factors in rheumatoid arthritis rats and play a good therapeutic effect. It works perhaps by inhibiting the activation of the TLR2/MyD88/NF-κB signaling pathway and thus shows an anti-inflammatory effect.

Mechanistic study on the solubility enhancement of puerarin by coamorphous technology / 药学学报

Puerarin (PUE), as an isoflavone component, has a wide range of pharmacological activities, while its poorly aqueous solubility limits the development of solid oral dosage forms. In this study, PUE along with nicotinamide (NIC) were prepared into the coamorphous system by solvent-evaporation method and characterized by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR). In addition, its dissolution behavior and solubilization mechanism were also investigated. PUE-NIC coamorphous was a single homogeneous binary system, with a single glass transition temperature at 35.1 ℃. In comparison to crystalline PUE, during the dissolution process, coamorphous PUE-NIC not only exhibited the "liquid-liquid phase separation" (LLPS) phenomenon, but the formation of Ap type complexation (1∶1 and 1∶2) between PUE and NIC molecules was also verified, which significantly improved the solubility of PUE and prolonged the supersaturation time, and would benefit its absorption.

MiR-183-5p Promotes Proliferation, Metastasis and Angiogenesis in Breast Cancer Cells through Negatively Regulating Four and a Half LIM Protein 1 / 한국유방암학회지

Purpose@#Four and a half LIM protein 1 (FHL1) is involved in breast cancer (BC) development, but the regulatory mechanism involved remain unclear. In the present study, we examined the role of FHL1 in BC development. @*Methods@#The expression of FHL1, miR-183-5p, and miR-96-5p in BC tissues was analyzed using StarBase analysis. FHL1 expression in BC tissues, a normal human breast epithelial cell line, and BC cell lines was detected using quantitative reverse transcription polymerase chain reaction (qRT-PCR). The relationship between FHL1 and miR-183-5p/miR-96-5p was analyzed via Pearson's rank correlation, TargetScan, and a dual-luciferase reporter assay. BT549 and MDA-MB-231 cells were transfected with either FHL1 and miR-183-5p mimics, or siFHL1 and a miR-183-5p inhibitor, respectively. The viability, colony number, migration, invasion, and tube length of BT549 and MDA-MB-231 cells were examined using cell counting kit-8, colony formation, wound-healing, Transwell, and tube formation assays, respectively. The levels of FHL1, vascular endothelial growth factor (VEGF), p53, E-cadherin, N-cadherin, and vimentin were quantified using western blotting and qRT-PCR. @*Results@#FHL1 expression was downregulated in BC tissues and cells, whereas miR-183-5p and miR-96-5p were upregulated in BC tissues (negative correlation with FHL1 expression).FHL1 overexpression inhibited the viability, colony number, migration, and invasion of BC cells and the expression of VEGF, N-cadherin, and vimentin, and increased the expression of FHL1, p53, and E-cadherin in BT549 cells. Furthermore, a miR-183-5p mimic reversed these effects of FHL1 overexpression, whereas FHL1 silencing caused opposite results to those observed in MDA-MB-231 cells; however, this was reversed by a miR-183-5p inhibitor. @*Conclusion@#Our study suggests that miR-183-5p promotes cell proliferation, metastasis, and angiogenesis by negatively regulating FHL1 in BC.

Bioinformatics analysis of differentially expressed circRNAs and microRNA-1 in HepG2 cells / 医学研究生学报

ObjectivecircRNAs play an important role in tumor development, but the relationship between circRNAs and hepatocellular carcinoma remains to be further explored. The present study aimed to bioinformatically analyze the target gene of microRNA-1. Another aim was to screen circRNAs that are associated with target genes and differentially expressed in hepatocellular carcinoma cells, as well as provide theoretical basis for clinical screening of molecular markers and targeted therapies related to hepatocellular carcinoma.MethodsThe miRNA related database used for the prediction of microRNA-1 target genes, and the bioinformatic analysis of the target genes of microRNA-1 involved functional enrichment analysis and signal transduction pathway enrichment. Then, the circRNAs, which are related to the downstream target genes of microRNA-1, are screened through the circRNA database.ResultsThe number of microRNA-1 target genes was 230 in miRNA related database. Through GO analysis, it was found that the target genes of microRNA-1 had a strong tendency in regulation, and were mainly enriched in three aspects: biological function, biological process and cell localization.The target genes of microRNA-1 are involved in the function of proteins, regulation of biosynthesis, cofactor binding, enzyme regulation and other biological processes. Predicted target genes of miRNA-1 were significantly enriched in cancer signaling pathways, hepatitis B occurrence, endocytosis and splicing pathways. Further, 21 circRNAs related to the target gene of microRNA-1 were found in three circRNA databases, wherein hsa_circ_0004651 was highly expressed in hepatocellular carcinoma cell line HepG2 and its pavent gene was hnRNPD.ConclusionMicroRNA-1 influence the occurrence of hepatocellular carcinoma development through the regulation of protein and enzyme. Hsa_circ_0004651 may affect the development of hepatocellular carcinoma with microRNA-1 and its parental gene hnRNPD.

Imaging Features of the Whole Uterus Volume CT Perfusion and Influence Factors of Blood Supply: A Primary Study in Patients with Cervical Squamous Carcinoma.

RATIONALE AND OBJECTIVES: To explore the imaging features of whole uterus volume CT perfusion (vCTP) and the influence factors of blood supply in cervical squamous carcinoma (CSC). MATERIALS AND METHODS: vCTP was performed on a 640-slice computed tomography system in 43 patients with CSC diagnosed by biopsy, and 24 cases of them underwent magnetic resonance imaging. The size of the tumor was measured on vCTP and magnetic resonance (MR) images. Perfusion parameters, including arterial blood flow (AF), blood volume, and permeability surface (PS), were measured by two radiologists, using interclass correlation coefficient to evaluate the interobserver reliability. The difference of tumor size and perfusion data was analyzed by paired t test and rank sum test. The correlation of perfusion parameters with some factors was analyzed by Pearson or Spearman correlation analysis. RESULTS: Tumor sizes were not significantly different between vCTP and MR images. The interclass correlation coefficient of each parameter was 0.818-0.945. The AF value of CSC was significantly higher than normal uterine body, and the blood volume and PS values of CSC were not statistically different compared with those of normal uterine body. There was no significant difference in AF value of CSC among different FIGO stages and pathological grades. The AF and PS values of CSC were negatively correlated with the age of the patients. CONCLUSION: The vCTP could accurately shows the size of the CSC with use of MR as the reference standard, and its perfusion parameters have good measurement stability; the CSC was hypervascular, but this trend was less pronounced in older women.

Analysis on potential factors of small for gestational age of Zhuang ethnicity in Wuming District of Nanning / 中华疾病控制杂志

Objective To understand the prevalence of small for gestational age (SGA) in Zhuang population, and to analyze the potential factors of SGA. Methods A total of 3 839 live births in the Wuming District People’s Hospital and Wuming Maternal and Child Health Hospital from January 2016 to January 2018 were recruited. Random Forest, 2 test and Logistic regression model were used for statistical analyses. Results The incidence of SGA was 9.6% (368/3 839), and it was 6.9% (142/2 049) and 12.6% (226/1 790) for male and female infants respectively. Random Forest method showed that second-trimester intrauterine growth restriction’s importance score was the highest, but gestational week’s was the lowest. Also, seven important variables were selected by this method. Unconditional logistic regression analysis showed that parity <2, the height of mothers <1.55 m, insufficient gestational weight gain, second-trimester intrauterine growth restriction were risk factors for SGA, but pre-pregnancy BMI ≥18.5 kg/m2 and male infants were protective factors. Conclusions The incidence of SGA is slightly higher, among the Zhuang population in Guangxi. SGA is affected by many factors. Therefore, it is necessary to evaluate the status of intrauterine growth and adopt comprehensive measures to control and reduce the incidence of SGA.

OBJECTIVE: To investigate the effects of different dose compatibility of Scutellaria baicalensis-Rheum palmatum-Coptis chinensis based on Sanhuang Xiexin decoction (shorted for Xiexin decoction) on dissolution rate of baicalin and baicalein, and to provide reference for studying chemical mechanism of TCM compound dose composition compatibility. METHODS: HPLC method was used to determine the contents of baicalin and baicalein. By fixing the dose of S. baicalensis (3 g), using the dose of R. palmatum and C. chinensis as factors, dissolution rate of baicalin and baicalein as response value, two-factor and five-level central composite test was designed. The optimal dose compatibility of S. baicalensis-R. Palmatum-C. chinensis was optimized by response surface method, and compared with the dissolution rate of baicalin and baicalein in classic dose Xiexin decoction (S. baicalensis 3 g, R. Palmatum 6 g, C. chinensis 3 g). RESULTS: When the doses of S. baicalensis, R. palmatum, C. chinensis were 3, 1. 76, 0. 17 g, total dissolution rate of baicalin and baicalein was the highest in extract. The average total dissolution rate of baicalin and baicalein in validation test was 21. 89％ (RSD=0. 46％, n=3),and the relative error was 2. 88％ with the predicted value of 22. 54％. Compared with the classical dose of Xiexin decoction, the total dissolution rate of baicalin and baicalein in the optimum dose of S. baicalensis-R. Palmatum-C. chinensis in extract was increased by 47. 21％. CONCLUSIONS: The different dose compatibility of S. baicalensis-R. Palmatum-C. chinensis based on Xiexin decoction influence the dissolution of baicalin and baicalein to certain extent. When the doses of S. baicalensis, R. palmatum, C. chinensis are 3, 1. 76, 0. 17 g, dissolution rate of baicalin and baicalein are higher than that of classic dose.

Outcomes of pregnancy among women with alpha-thalassemia minor: A retrospective study of Pingguo county in Guangxi Zhuang Autonomous Region / 中华流行病学杂志

Objective To investigate the association between the value of α-thalassemia minor and the outcomes in pregnant women.Methods A total of 445 pregnant women with α-thalassemia minor were selected as thalassemia group in the Pingguo County Maternal and Child Health Hospital of Guangxi from January 2011 to December 2015,with ratio of 1 ∶ 4 healthy pregnant women was randomly recruited as non-thalassemia group.Clinical characteristics and pregnancy outcomes of the two groups were retrospectively analyzed using methods including t test,x2 test,and logistic regression model and ROC curve.Results There were no significant differences noticed in factors as age,BMI,gestational age and educational level of the two groups.Hemoglobin of the thalassemia group was significantly lower than that of the non-thalassemia group (P＜0.001).Differences on parity,ethnicities or occupation were statistically significant.Results from univariate analysis showed that the proportions of low birth weight,small for date infant and 1 min Apgar score ＜7 were higher in the thalassemia group,but the ratio of adverse pregnancy outcomes was comparable on parameters as preterm birth,stillbirth,macrosomia.Findings from the unconditional logistic regression showed that pregnancy complicated with α-thalassemia minor appeared a risk for both newboms with low birth weight (aOR=2.29,95％CI:1.32-3.95) and small for date infant (aOR=2.11,95％ CI:1.16-3.84).The ROC curve showed that α-thalassemia minor combined with multiple indicators presented a certain predictive value on neonatal birth weight.Conclusion Pregnancy complicated with α-thalassemia minor was likely to increase the risk of birth weight loss in newborns,suggesting that prenatal care for pregnant women with thalassemia be strengthened,in order to reduce the incidence of adverse pregnancy outcomes.

Correlation between drug -resistance gene mutations and hepatocellular carcinoma in patients with hepatitis B virus infection / 临床肝胆病杂志

Objective To investigate the correlation between hepatitis B virus (HBV)drug -resistance gene mutations and hepatocellular carcinoma (HCC).Methods The clinical data of treatment -experienced patients,who underwent examination for HBV drug -resistance gene mutations in Beijing Ditan Hospital from January 1 to December 31,2013,and still had detectable HBV DNA after being treated with nucleos(t)ide analogues,were collected.All the patients were followed up,and the development of HCC was considered as the clinical out-come.The correlation between drug -resistance gene mutations and the development of HCC in patients with HBV infection was analyzed. The chi -square test was used for comparison of categorical between groups,the t -test was used for comparison of continuous data between two groups,and the log -rank test was used for comparison of the incidence of HCC between two groups.Results A total of 227 patients were enrolled in this study.According to the results of the detection of HBV drug -resistance gene mutations,103 patients (103 /227, 45.37%)had no drug -resistance gene mutations and 124 (124 /227,54.63%)had drug -resistance gene mutations.There were no sig-nificant differences between the mutation group and the non -mutation group in HBV DNA load (5.19 ±1.60 log10 IU /ml vs 5.44 ±1.75 log10 IU /ml,t =-1.134,P =0.258)and the percentage of patients with liver cirrhosis (24.19% (30 /124)vs 16.50% (17 /103),χ2 =2.026,P =0.155).The median follow -up was 28 months (range 4 -58 months),and the incidence of HCC was 7.49% (17 /227).A-mong the patients with HBV drug -resistance gene mutations,12 (12 /124,9.68%)developed HCC,and among those without HBV drug-resistance gene mutations,5 (5 /103,4.85%)developed HCC.Among the patients who developed HCC,70.59% (12 /17)had HBV drug -resistance gene mutations at baseline;among the patients who did not develop HCC,53.33% (112 /210)had HBV drug -resistance gene mutations at baseline.Conclusion The patients with poor control of HBV DNA during antiviral therapy have a comparable incidence of HCC to those not treated with antiviral therapy,with a relatively high risk of developing HCC;the treated patients with HBV drug -resist-ance gene mutations may have a higher risk of HCC than those without such mutations,which needs to be confirmed by the studies with a longer follow -up period and a larger sample size.

Compatibility Rule of Herb-pair in Rhubarb Based on Anti-inflammation Function / 医药导报

Objective To study compatibility rule of herb-pair in rhubarb after compatibilities with fructus aurantii Immaturus,Chinese goldthread rhizome,moutan cortex,peach seed and kansui radix stir-baked with vinegar, and to observe its anti-inflammation and acute toxicity. Methods Mice were gavaged by 15,30 g?kg-1 rhubarb and rhubarb, rhubarb frutus aurantii immaturus rhizoma coptidis, radix et rhizoma rhei peony, rhubarb, semen persicae and rhubarb extracts from euphorbia kansui, respectively, in the morning and evening once, for 7 d.The effects of five different compatibility of Rhubarb on acute inflammation were observed in the mouse paw swelling induced by carrageenan. The classical method were used to determine acute toxicity of rhubarb and the contents of five different compatibility of rhubarb. Results Compared with the control group, the contents of five different compatibility of rhubarb with high and low dosage groups(30,15 g?kg-1 ) could inhibit the paw edema in mice,reduce NO and MDA production and enhanced activity of SOD in mice inflammatory tissue. The LD50 was not determined. Calculated by crude drug content, the MLD of rhubarb compatibilities with fructus aurantii immaturus, Chinese goldthread rhizome,moutan cortex,peach seed and kansui radix stir-baked with vinegar were 145.33,142.30,117.53,103.45, 113.09,182.36 g?kg-1 respectively, which were respectively equal to 581,569,470,418,452 ,729 times of people, s daily dried medicinal herb dosage. Conclusion The five different herb-pair have anti-inflammation effects after compatibility of Rhubarb, and it got best effects when rhubarb compatibility with kansui radix stir-baked, the next were rhubarb compatibility with Chinese goldthread rhizome and moutan cortex. It was basic security and low toxicity of herb-pair in rhubarb after compatibilities.
