Chinese Journal of Primary Medicine and Pharmacy 2024;31(5):686-690
Objective:To investigate the association between fasting blood glucose (FBG) variability and the risk of developing gestational diabetes mellitus.Methods:Ninety patients with gestational diabetes mellitus admitted to Jiaxing Maternity and Child Health Care Hospital between January 2022 and April 2023 were included in this study. Based on the blood glucose results obtained from the 75 g oral glucose tolerance test, these patients were divided into two groups: the normal blood glucose group (Group A, n = 56) and the elevated blood glucose group (Group B, n = 34). Multivariate logistic binary regression analysis was conducted to identify independent risk factors for gestational diabetes mellitus. Additionally, an analysis was conducted to investigate the association between long-term fasting blood glucose standard deviation (SD FBG), coefficient of variation (CV FBG), average successive variability of fasting blood glucose (ASV FBG), and the severity of gestational diabetes mellitus. Results:The FBG levels [(6.83 ± 1.03) mmol/L vs. (4.62 ± 0.58) mmol/L], 1-hour postprandial blood glucose [(13.03 ± 1.39) mmol/L vs. (11.42 ± 1.04) mmol/L], and 2-hour postprandial blood glucose [(10.23 ± 1.51) mmol/L vs. (9.42 ± 0.74) mmol/L] between the two groups ( F = 887.43, 144.76, 10.39, all P < 0.05). Furthermore, the glycated hemoglobin levels were significantly elevated in Group B [(7.19 ± 1.01) mmol/L] compared with Group A [(5.03 ± 0.42) mmol/L, t =14.15, P < 0.05). When compared with Group A, patients in Group B exhibited significantly higher values for ASV FBG [(0.58 ± 0.23) mmol/L vs. (0.36 ± 0.26) mmol/L], SD FBG [(0.55 ± 0.38) mmol/L vs. (0.41 ± 0.21) mmol/L], and CV FBG [(9.43 ± 2.45) mmol/L vs. (6.94 ± 1.31) mmol/L] ( t = 4.06, 2.25, 6.28, all P < 0.05). Additionally, the age and pre-pregnancy body mass index were significantly higher in Group B compared with Group A ( t = 3.82, 7.53, both P < 0.05). Age, pre-pregnancy body mass index, fasting blood glucose, 1-hour postprandial blood glucose, 2-hour postprandial blood glucose, glycated hemoglobin, ASV FBG, SD FBG, and CV FBG were identified as risk factors for severe gestational diabetes mellitus ( OR = 1.230, 1.887, 301.406, 3.957, 1.947, 41.861, 5.421, 2.057, all P < 0.05). Furthermore, SD FBG, ASV FBG, and CV FBG were positively correlated with the severity of gestational diabetes mellitus ( r = 0.234, 0.555, 0.408, all P < 0.05). Conclusion:Fasting blood glucose variability is positively correlated with the risk of developing gestational diabetes mellitus. Age, pre-pregnancy body mass index, fasting blood glucose, 1-hour postprandial blood glucose, 2-hour postprandial blood glucose, glycated hemoglobin, ASV FBG, SD FBG, and CV FBG are also risk factors affecting the severity of gestational diabetes mellitus.

Tumor metastasis depends on the dynamic balance of the actomyosin cytoskeleton. As a key component of actomyosin filaments, non-muscle myosin-IIA disassembly contributes to tumor cell spreading and migration. However, its regulatory mechanism in tumor migration and invasion is poorly understood. Here, we found that oncoprotein hepatitis B X-interacting protein (HBXIP) blocked the myosin-IIA assemble state promoting breast cancer cell migration. Mechanistically, mass spectrometry analysis, co-immunoprecipitation assay and GST-pull down assay proved that HBXIP directly interacted with the assembly-competent domain (ACD) of non-muscle heavy chain myosin-IIA (NMHC-IIA). The interaction was enhanced by NMHC-IIA S1916 phosphorylation via HBXIP-recruited protein kinase PKCβII. Moreover, HBXIP induced the transcription of PRKCB, encoding PKCβII, by coactivating Sp1, and triggered PKCβII kinase activity. Interestingly, RNA sequencing and mouse metastasis model indicated that the anti-hyperlipidemic drug bezafibrate (BZF) suppressed breast cancer metastasis via inhibiting PKCβII-mediated NMHC-IIA phosphorylation in vitro and in vivo. We reveal a novel mechanism by which HBXIP promotes myosin-IIA disassembly via interacting and phosphorylating NMHC-IIA, and BZF can serve as an effective anti-metastatic drug in breast cancer.

Objective:To understand the real experience and feeling of Intensive Care Unit (ICU) nurses after delirium assessment using Cornell Assessment of Pediatric Delirium (CAPD) , so as to provide reference and evidence for improving pediatric ICU delirium assessment.Methods:Using the purposive sampling method, a total of 11 ICU nurses who used CAPD for pediatric delirium assessment in a ClassⅢ Grade A children's specialized hospital in Shanghai from February to April 2020 were selected as the research objects. Phenomenological research method in qualitative research was used to conduct face-to-face and semi-structured in-depth interviews with the research subjects. Colaizzi 7-step analysis method was used to collect and sort the data and analyze and refine the topics.Results:ICU nurses' cognition in pediatric delirium assessment could be classified into four themes, including changes of ICU nurses' cognition of pediatric delirium assessment, obstacles to pediatric delirium assessment, promoting factors for pediatric delirium assessment, and ICU nurses' concern about the collaborative intervention of medical team after the positive delirium assessment.Conclusions:The main manifestations of ICU nurses in this study are the lack of understanding of the evaluation of delirium, the obstacles encountered in the evaluation process, and the lack of collaboration between the medical and nursing team. In order to improve the convenience and accuracy of ICU nurses' assessment of delirium, it is recommended to strengthen the training of medical staff for delirium, gradually optimize the obstacles to the implementation of the assessment, encourage the cooperation of medical teams and develop a delirium assessment process in line with children's ICU according to the working situation and mode of ICU.

A quail-origin subtype of the influenza virus was isolated from a human-infecting H7N9 subtype of the avian influenza virus found in a live poultry market and was given the name A/Quail/Hangzhou/1/ 2013 (H9N2). We analyzed the whole genome of this virus and its biologic characteristics. Sequence analyses suggested that the: HA and NS genes belonged to a CK/BJ/1/94-like lineage; NA, NP, PA and PB1 genes belonged to a SH/F/98-like lineage; M and PB2 genes belonged to a G1-like lineage. Analyses of key amino acids showed that the cleavage site in HA protein was PSRSSR ↓ GL, and that the HA protein had a human receptor-binding site with Leu226. Deletion of amino acids 69 - 73 was detected in the stalk of NA protein, the M2 protein had an Asn31 mutation, and the NS1 protein had two mutations at Ser42, Ala149. The intravenous pathogenicity of this virus was 0.36. A study in chickens suggested that all inoculated birds shed the virus from the trachea and cloaca on the third day post-infection (p. i. ) until 11 days. All chickens that had direct contact shed the virus on the second day p. i. until 8 days. Results of virus reisolation suggested that lung and tracheal tissues could shed the virus in 5 days, whereas the other organs could shed the virus in 3 days. These results suggest that this virus strain is H9N2 subtype LPAIV, whose lineage is prevalent in mainland China. This research provides evidence on how to monitor and prevent the H9N2 subtype of the avian influenza virus.

Objective To investigate the characteristics of activation-induced cytidine deaminase (AID) expression level in de novo acute leukemia (AL) patients, chronic myeloid leukemia chronic phase (CML-CP), chronic myeloid leukemia blastic crisis (CML-BC) patients and leukemia cell lines. Methods The expression level of AID mRNA was measured in 89 cases of newly-diagnosed acute lymphoblastic leukemia (ALL) patients, 79 cases of de novo acute myeloid leukemia (AML) patients, 5 cases of CML-BC patients, 5 cases of CML-CP patients and leukemia cell lines NB4, THP-1, KG-1, Raji, K562 by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR), bone marrow mononuclear cells of 16 normal healthy donors were used as the control group. Results The expression levels of AID mRNA in 89 cases of ALL and 79 cases of AML were 0.006-7 463.175 and 0.005-69.107, the median expression levels were 3.785 and 1.812, the expression level of AID mRNA in the normal control group was 0.146-4.707, and the median expression level was 1.483, respectively. The AID expression levels of ALL, B-ALL, Burkitt leukemia, M4 patients and Raji cells were significantly higher than those of the normal control group (all P <0.05). Nevertheless, the AID mRNA expression levels of M3 patients and NB4, KG-1 cells were lower than those of the normal control group (all P <0.05). Furthermore, the AID mRNA expression levels of K562 cell were strikingly higher than that of the CML-CP patients (P<0.001), so were those of CML-BC, chronic myeloid leukemia myeloid blast crisis (CML-MBC), chronic myeloid leukemia lymphoblastic blast crisis (CML-LBC) patients. Conclusion AID gene shows high expression level in B-ALL, Burkitt leukemia and M4, low expression level in M3 and KG-1 cells, and obvious high expression level in CML-BC.
