Objective To evaluate the efficacy of Huachansu tablets combined with transarterial chemoembolization(TACE)for treatment of primary hepatocellular carcinoma(HCC)and prognostic influence factors.Methods One hundred and eight patients with HCC were recruited according to the inclusion and exclusion criteria.Patients were randomly divided into treatment group and control group.The treatment group was treated with Huachansu tablets combined with TACE,and the control group was treated with TACE alone,with overall survival time(OS)and progression-free survival time(PFS)as the evaluation indexes.The COX regression analysis was used to evaluate the survival and prognostic effects and their influence factors in both groups.Results A total of 108 HCC patients were enrolled.The OS was 13.5 months in treatment group and 9.2 months in control group;the PFS was 6.8 months in treatment group and 5.3 months in control group,and the differences were significant statistically(all P<0.05).Multivariate COX regression analysis showed that Child-Pugh grade and cirrhosis were the independent risk factors for PFS in HCC patients.Child-Pugh grade were the independent risk factors for OS in HCC patients.ALBI is a protective factor for OS in HCC patients.Conclusions The treatment of HCC by Huachansu tablets combined with TACE can delay the progression of HCC and prolong PFS and OS of the patients with HCC.Child-Pugh grade,cirrhosis status,and ALBI were important factors affecting the prognosis of the patients with HCC.

Objective:To exlplore the association between the baseline luteinizing hormone/follicle stimulating hormone (LH/FSH) ratio of polycystic ovary syndrome (PCOS) and in vitro fertilisation-embryo transfer outcomes.Methods:This was a retrospective cohort study. A total of 2 868 PCOS patients were enrolled, all of the participants were patients in The First Affiliated Hospital of Anhui Medical University Hospital from October 2015 to October 2021. Propensity score matching (1∶2.5) was conducted to regulate the non-random allocation of patients. Data were extracted from the hospital′s medical records. Patients with baseline LH/FSH ratio>2 were deemed as study group, patients with baseline LH/FSH ratio≤2 were deemed as control group. Single factor analysis was applied to compare the differences of pregnancy outcomes between two groups.Results:After propensity score matching (1∶2.5), there were no statistically significant differences in baseline data between the two groups (all P>0.05), indicating that the data were comparable. In the study group, the total dose of gonadotropin (Gn) and duration of Gn were lower than those of the control group ( t=4.989, P<0.001; t=3.267, P=0.001), the rate of in vitro maturation was higher than that of the control group ( χ2=4.938, P=0.026), the number of retrieved oocytes and cleavage were higher than those of the control group ( t=-2.305, P=0.021; t=-2.816, P=0.005), but there were no differences in the number and rate of high-quality embryos between the two groups ( t=-1.636, P=0.102; t=-0.123, P=0.902). The incidence of moderate to severe ovarian hyperstimulation syndrome in the study group was significantly higher than that in the control group ( χ2=17.277, P<0.001). Regardless of fresh embryo transfer or frozen-thawed embryo transfer cycles, the incidences of gestational diabetes mellitus in the study group were higher than those in the control group ( χ2=9.174, P=0.002; χ2=4.204, P=0.040) of singleton pregnancy. In the fresh embryo transfer cycle, the clinical pregnancy rate [30.30% (20/66) vs 47.75% (53/111)] and delivery rate [30.30% (20/66) vs 46.85% (52/111)] in the study group were lower than those in the control group ( χ2=5.198, P=0.023; χ2=4.695, P=0.030). In the frozen-thawed embryo transfer cycle, the delivery rate in the study group was higer than that in the control group [59.41% (423/712) vs 55.04% (1 053/1 913); χ2=7.526, P=0.023]. The clinical pregnancy rate and delivery rate of fresh embryo transfer cycle in the study group were significantly lower than those of frozen-thawed embryo transfer cycle ( χ2=21.308, P<0.001; χ2=20.871, P<0.001), but there were no significant differences in the control group (all P>0.05). Conclusions:PCOS patients with a higher basal LH/FSH ratio are more likely to develop moderate to severe ovarian hyperstimulation syndrome after controlled ovarian stimulation and have a higher incidence of gestational diabetes mellitus. Better pregnancy outcome could be obtained by frozen-thawed embryo transfer.

Itaconate is a pivotal intermediate metabolite in the tricarboxylic acid (TCA) cycle of immune cells. It is produced by decarboxylation of cis-aconitic acid under the catalysis of aconitate decarboxylase 1 (ACOD1), which is encoded by the immune response gene 1 (IRG1). Itaconate has become a focal point of research on immunometabolism. Studies have demonstrated that itaconate plays a crucial role in diseases by regulating inflammation, remodeling cell metabolism, and participating in epigenetic regulation. This paper reviewed the research progress in itaconnate from its chemical structure, regulatory effects on different diseases, and mechanisms, proposes the future research directions, aiming to provide a theoretical basis for the development of itaconate-related drugs.

Ten-eleven translocation 1 (TET1) protein is an alpha-ketoglutaric acid (α-KG) and Fe²⁺-dependent dioxygenase. It plays a role in the active demethylation of DNA by hydroxylation of 5-methyl-cytosine (5-mC) to 5-hydroxymethyl-cytosine (5-hmC). Ten-eleven translocation 1 (TET1) protein is involved in maintaining genome methylation homeostasis and epigenetic regulation. Abnormally expressed TET1 and 5-mC oxidative derivatives have become potential markers in various biological and pathological processes and a research focus in the fields of embryonic development and malignant tumors. This paper introduces the structure and demethylation mechanism of TET1, reviews the research status of epigenetic regulation by TET1 in embryonic development, immune responses, stem cell regulation, cancer progression, and nervous system development, and briefs the upstream regulatory mechanism of TET1, hoping to provide new inspirations for further research in related fields.

Objective:To understand the status of psychological capital and disaster preparedness of clinical nurses and analyze the relationship between them.Methods:From August to October 2020, 508 clinical nurses were selected from 8 Class Ⅲ hospitals in Zhejiang province by convenience sampling method. General information questionnaire, nurses' psychological capital questionnaire and disaster preparedness questionnaire were used. A total of 508 questionnaires were sent out and 503 valid questionnaires were collected with an effective rate of 99.01%.Results:The total score of disaster preparedness score of 503 clinical nurses was (179.53±41.11) points, mean items score was (3.99±0.91) points, psychological capital was (91.86±14.68) points, mean items score was (4.49±0.73) points. Correlation analysis showed that nurses' psychological capital was positively correlated with disaster preparedness ( r value was 0.610, P<0.05). Regression analysis showed that psychological capital, department, working years, whether participated in disaster training and disaster event rescue had significant impact on disaster preparedness of clinical nurses ( t values were 2.002-16.770, P<0.01 or 0.05). Conclusions:The knowledge, skills and post disaster management of clinical nurses are still deficient. Psychological capital affects the level of disaster preparedness of nurses to a certain extent. Nursing managers should formulate targeted intervention measures to enhance the level of psychological capital of nurses, so as to better improve the disaster preparedness of clinical nurses.

Objective To understand the status of type 2 diabetes mellitus (T2DM) patients′ trust in their family physicians, and to explore the role of the trust on patients′ medication adherence. Methods A total of 1078 patients with T2DM were recruited by cluster and systematic sampling method, from ten rural communities in Sanlong township in Yancheng city and five rural communities of Pingchao township in Nantong city, during February to April in 2018. The survey covered their trust behavior and attitude scale (PTBAS), and an 8-item Morisky medication adherence scale ( MMAS-8). Both measurement data and enumeration data were subject to descriptive analysis by mean ± SD and proportion respectively. Multiple linear regression was employed to explore the determinants of trust in physicians. Ordered logistic regression analysis was used to explore the relationship between patient-physician trust and medication adherence. Results The mean scoring of patients′ trust and medication adherence was 20. 16 ± 2. 13, 7. 07 ± 1. 54 respectively. 55. 40 percent of the patients had high medication compliance, 28. 53 percent of them had medium compliance and 16. 07 percent had poor compliance. Multiple linear regression analysis showed that the patient′s occupation, course of disease, self-reported health status and mental health status influenced their trust behavior (P < 0. 05). Ordered logistic regression analysis showed that each 1 point increase in patient′s trust in physicians, the medication compliance increased by 11. 0％ (OR = 1. 110, P < 0. 001). Medication adherence is also affected by age, employment status, course of illness, and mental health status. Conclusions Diabetes patients′ trust in their family physicians improves their medication adherence.

OBJECTIVETo investigate the effects of a recombinant adenovirus-mediated triple mutant hypoxia-inducible factor-1α (HIF-1α) on the proliferation and vascular endothelial growth factor (VEGF) expression in human microvascular endothelial cells (hMVECs).

METHODSThe adenovirus vector of the triple mutant HIF-1α (Ad-HIF-1α(564/402/803)), adenovirus vector of wild-type HIF-1α (Ad-HIF-1α(nature)), Ad-lacZ and Ad-Null were amplified in HEK293A cells, and the adenoviruses were purified and titrated. Dual luciferase reporter assay system was employed to detect the transcriptional activities of wild-type and triple mutant HIF-1α. After infection of the hMVECs with the adenoviruses, the cellular protein expressions of HIF-1α and VEGF were detected using Western blotting, and the cell proliferation was assessed by MTS assay.

RESULTSThe transcriptional activity of the triple mutant HIF-1α was significantly higher than that of wildtype HIF-1α in the infected hMVECs (P<0.001). The protein levels of HIF-1α and VEGF in cells infected with Ad-HIF-1α(564/402/803) were significantly higher than those in cells infected with other adenoviruses, and HIF-1α dose-dependently up-regulated VEGF protein expression. The absorbance was significantly higher in Ad-HIF-1α(564/402/803) group than in the other groups (P<0.01) on the third and fifth days after infection.

CONCLUSIONThe recombinant adenovirus-mediated triple mutant HIF-1α expression is stable under normoxic condition. The triple mutant HIF-1α can up-regulate the expression of VEGF protein in hMVECs to promote the cell proliferation.
