Objective To analyze the influencing factors of malaria infection of labor service exported to overseas in Langfang City, in order to establish a visualization tool to assist clinicians in predicting the risk of malaria. Methods A total of 4 774 expatriate employees of the Nibei Pipeline Project of the Pipeline Bureau from October 2021 to August 2023 were taken as the subjects, and the gender, age, overseas residence area and Knowledge of malaria controlscores of the study subjects were investigated by questionnaire survey, and the possible risk factors of malaria were screened by logistic regression model. At the same time, the nomogram prediction model was established, and the subjects were divided into the training group and the validation group at a ratio of 2:1, and the area under the curve (ROC) and the decision curve were plotted to evaluate the prediction ability and practicability of the prediction model in this study. Results Among the 4 774 study subjects, 96 cases of malaria occurred, and the detection rate was 2.01%. Junior school （OR=1.723，95% CI:1.361-2.173）， and residence in rural areas（OR=2.091，95%CI:1.760 -3.100）were risk factors (OR>1), while protective measures（OR=0.826，95% CI : 0.781 - 0.901） and high malaria education scores （OR=0.872，95% CI : 0.621 - 0.899）were protective factors.The nomogram prediction model results showed that the area under the curve of the nomogram prediction model in the training group was 0.94 (95% CI : 0.85 - 1.00), while the validation group was 0.93 (95% CI : 0.80 - 1.00). The results of the decision curve showed that when the threshold probability of the population was 0-0.9, the nomogram model was used to predict the risk of malaria occurrence with the highest net income. Conclusion The nomogram prediction model (including gender, education, region, protection and malaria education score) established and validated in this study is of great value for clinicians to screen high-risk patients with malaria.

Objective:To investigate the role of ubiquitin-specific protease 21 (USP21) in enterovirus group A type 71 (EV-A71) infection.Methods:Peripheral blood mononuclear cells (PBMC) were obtained from a cohort of 24 children infected with EV-A71 and 24 healthy children. Expression of USP21 was determined by real-time fluorescence quantitative PCR (qPCR). Additionally, the impact of USP21 overexpression or knockout on EV-A71 replication was evaluated using a combination of qPCR and western blot (WB) analysis. Furthermore, WB was employed to measure the levels of EV-A71 structural protein VP1, phosphorylated interferon regulatory factor 3 (IRF3) and other key molecules in the RIG-I-like receptor (RLR) signaling pathway. Co-immunoprecipitation (Co-IP) was utilized to investigate the effects of USP21 on the ubiquitin levels of EV-A71 nonstructural protein 2A protease (2A pro). Results:In comparison to healthy children, the expression of USP21 mRNA in PBMC of children infected with EV-A71 was notably elevated. The overexpression of USP21 significantly enhanced the cytopathic effects induced by EV-A71, upregulated levels of VP1 mRNA and protein, and facilitated EV-A71 replication, leading to a decrease in cell activity with increasing levels of USP21 transfection. Following the knockout of the USP21 gene, the VP1 mRNA levels were significantly declined in comparison to the control group. Furthermore, the overexpression of USP21 was found to have no impact on the transcriptional activity of EV-A71 2A pro. However, it was observed to enhance the expression of 2A pro protein, reduce the ubiquitination of 2A pro, suppress the protein levels of mitochondrial antiviral signaling protein (MAVS) and melanoma differentiation-associated gene 5 (MDA5), as well as decrease the phosphorylation of IRF3. Additionally, the induction of IFN-β mRNA by EV-A71 infection was downregulated. Conclusions:USP21 has been shown to enhance the replication of EV-A71 through the downregulation of 2A pro ubiquitination, suppression of MAVS and MDA5 protein expression, and inhibition of the interferon signaling pathway.

PANoptosis, a newly defined form of cell death, is characterized by the simultaneous occurrence and crosstalk of apoptosis, pyroptosis, and necroptosis. It has emerged as a promising therapeutic target for various diseases. Ovarian dysfunction is marked by oligomenorrhea or amenorrhea, elevated gonadotropin levels, and diminished estrogen levels, often accompanying subfertility or infertility. Additionally, it can manifest with perimenopausal syndrome and increase the risks of osteoporosis, cardiovascular disease, and cognitive impairments, seriously impacting patients' quality of life. While current studies have reported that ovarian hypofunction is associated with apoptosis, pyroptosis, or necroptosis, a systematic investigation into the relationship between PANoptosis and ovarian hypofunction is still absent. This review aims to elucidate the potential link between these two phenomena, providing new insights into the mechanisms underlying ovarian hypofunction and potential treatment strategies.

Objective::To examine the impact of hypertensive disorders of pregnancy (HDP) on offspring metabolomics.Methods::We searched five databases: PubMed, Ovid Embase, MEDLINE, Web of Science, and China National Knowledge Infrastructure, and included studies that reported metabolomics among human offspring born to HDP-complicated pregnancies.Results::Database search yielded 4054 articles, and after full-text screening, ten observational studies met inclusion criteria. Half of the studies had a sample size of less than 100 and were all observational studies in preeclampsia (PE) and gestational hypertension.Neonates were the most focused group in all included studies. Offspring born to HDP-complicated pregnancies exhibited statistically significant variations in blood metabolomics compared to their counterparts, characterized by amino acids, lipids, carnitine, and others (e.g., 1α,25-(OH) 2-D). Most studies reported a significant increase in differential metabolites of offspring born to HDP-complicated pregnancies. Four studies ( n = 1109) measured lipids-related metabolites, and all consistently showed that offspring born to PE-complicated pregnancies had significantly higher concentrations than non-PE exposed offspring. Conclusion::The existing evidence suggests an intergenerational effect of HDP on offspring metabolomics. Long-term follow-up studies are needed to advance the health effects of related adverse health outcomes and inform the prevention of offspring’s health.

Objective:To investigate the role of speckle-type POZ(pox virus and zinc finger protein) protein (SPOP) in enterovirus 71 (EV71) infection.Methods:Immunoprecipitation analysis was employed to examine the impact of SPOP on the ubiquitin level of EV71 non-structural protein 2A protease (2A pro), while the phosphorylation level of IFR3 protein was assessed through Western blot. Cells were either overexpressed or knockdown of SPOP, followed by infection with EV71. RT-qPCR was utilized to analyze the transcription level of IFN-β, and the transcription level and protein level of EV71 structural protein VP1 were determined using RT-qPCR and Western blot, respectively. Results:The inhibition of EV71 infection in RD cells was observed following transfection with HA-SPOP. Additionally, it was found that the ubiquitin level of EV71-2A pro increased in a gradient-dependent manner. Subsequent transfection with shSPOP plasmid for endogenous SPOP knockdown resulted in a dose-dependent decrease in the levels of melanoma differentiation-associated gene 5 (MDA5), mitochondrial antiviral signaling (MAVS), and p-IRF3. Conversely, transfection with HA-SPOP plasmid led to a dose-dependent increase in the levels of MDA5, MAVS, and p-IRF3. The expression of SPOP, whether high or low, had an impact on the expression of IFN-β in cells. Additionally, the levels of VP1 mRNA or protein were found to be inhibited or increased. Conclusions:SPOP plays a role in increasing the ubiquitination level of EV71-2A pro, which in turn promotes the phosphorylation level of IRF3 and secretion of IFN-β. This effect is achieved by inhibiting the cleavage of 2A pro against key molecules MAVS and MDA5 in the RLR signaling pathway, ultimately leading to the inhibition of EV71 replication.

Objective:To analyze the early identification, clinical characteristics, diagnosis and treatment of gestational hypertension crisis combined with adrenal disease.Methods:The clinical data of 23 patients of HCP complicated with adrenal disease admitted from Jul. 2009 to Jul. 2019 were retrospectively studied. The clinical characteristics, imaging characteristics, treatment and clinical transfer were studied.Results:The occurrence of all the 23 cases were acute. Among them, 16 cases had eclampsia combined with Cushing’s syndrome, 4 cases were pregnancy combined with primary aldosteronism (PA) and extreme hypokalemia, and 3 cases had eclampsia combined with pheochromocytoma (PHEO) . After admission, the patients were given symptomatic support treatment for sedation, analgesia, blood pressure control, dehydration, cranial pressure reduction, electrolyte balance and spasmolysis, and patients with severe preeclampsia and preeclampsia terminated their pregnancy in time. After treatment, 3 patients gave live birth, 12 received postpartum surgical treatment and 10 received drug treatment. The clinical symptoms improved and imaging examination suggested the lesions in the brain narrowed and disappeared, except one patient had major cerebral hemorrhage and died of multiple organ failure.Conclusions:In case of HCP and severe hypokalemia, relevant examinations should be improved in combination with symptoms to comprehensively diagnose whether it is complicated with adrenal diseases. The treatment methods and process of HCP with adrenal diseases need to be optimized, so as to judge the timing of termination of pregnancy, and minimize the impact on mother and fetus.

Objective:To investigate the prognosis and influencing factors of secondary cytoreductive surgery (SCS) combined with chemotherapy in the treatment of recurrent ovarian cancer.Methods:A total of 102 patients with recurrent ovarian cancer admitted to our hospital from Jun. 2012 to Jun. 2015 were selected and grouped according to treatment methods. 31 patients who received paclitaxel/carboplatin (TC) chemotherapy were included in the control group, and 71 patients who received SCS combined with TC chemotherapy were included in the observation group. Clinical efficacy and 5-year survival outcome of the two groups after treatment, were compared and factors affecting the prognosis of the observation group were analyzed.Results:The total effective rate, 1-year survival rate, 3-year survival rate, and 5-year survival rate of the observation group were significantly higher than those of the control group. The median survival time of the observation group was 52 months and was significantly longer than that of the control group by 17 months ( P<0.05) ; There was no statistical difference between the death group and the survival group in terms of age, pathological type, tissue differentiation, recurrence tumor size, or location of recurrence tumors. The number of patients with FIGO stage IV, more than 3 recurrent tumors, ascites and residual lesion size >1 cm in the death group were significantly larger than those in the survival group. The serum CA125 level of patients in the death group was significantly higher than that in the survival group. Logistic regression analysis showed that the number of recurring tumors>3, with ascites, and residual lesions>1 cm, and high level of CA125 were independent risk factors for death after SCS combined with TC chemotherapy ( P<0.05) . Conclusions:SCS combined with chemotherapy can effectively improve the therapeutic effect, relieve the clinical symptoms, improve the survival rate of patients, and prolong the survival time of patients. The prognosis of SCS combined with chemotherapy is affected by the number of recurrent tumors, the presence or absence of ascites, the size of residual lesions, and CA125 level. The prognosis and survival of patients can be improved by adopting appropriate treatment.

Objective To study the trends of lung cancer mortality among adult residents in Macheng City, Hubei Province from 1984 to 2018． Methods Mortality data was extracted from Macheng City disease surveillance points (DSPs) system and China Demographic Yearbook. The age-period-cohort (APC) model and Intrinsic Estimator algorithm were used to estimate the age effect, period effect and cohort effect of lung cancer mortality. Results The age effect coefficient of lung cancer mortality increased with age from 20 to 74 years old. The mortality risk of the 70-74 group was 42.62 times that of the 20-24 group. The period effect coefficient of lung cancer mortality also continued to rise with time. The cohort effect coefficient was parabolic, and residents born in 1939-1943 had the highest coefficient (1.298 4). Conclusion The risk of lung cancer death of adult residents in Macheng City significantly increased with the year and the rapid development of socio-economics.
