Background The high work intensity and possible subsequently increased susceptibility to occupational hazards of calcium carbide plants may lead to hypertension in workers, but there are few studies on the relationship between occupational hazard exposure and hypertension in workers involving the production process of calcium carbide. Objective To explore the influence of occupational hazards on the incidence of hypertension in calcium carbide plants. Methods Using historical cohort design, the employees of a calcium carbide factory in the western part of Inner Mongolia Autonomous Region were selected as research subjects. According to the pre-determined inclusion and exclusion criteria, the study population comprised an exposure group of 377 employees (including furnace workers, inspection workers, and maintenance workers) exposed to dust, noise & carbon monoxide, and a control group of 388 employees (including central control workers, electricians, and administrative personnel) without above-mentioned exposure. The total sample size was 765 participants. The follow-up period was from April 2011 to October 2022, and the study endpoint was defined as the conclusion of the follow-up period or diagnosed hypertension in annual occupational health examination. Information on general demographic characteristics, living habits, and work status was collected from all study subjects. Cox proportional hazards regression model was used to analyze the association between occupational hazard exposure and the risk of hypertension among the calcium carbide plant employees. Results The average age, mean systolic and diastolic blood pressure, proportion of males, smoking rate, and alcohol consumption rate in the exposure group were higher than those in the control group (P<0.05). Compared to baseline, both systolic and diastolic blood pressure levels increased in the exposure group and the control group at the end of the follow-up (P<0.05). At the end of the follow-up, the average differences between systolic/ diastolic blood pressure and baseline values in the exposure group were higher than those in the control group (P<0.05). During the follow-up period, a total of 223 cases of hypertension occurred, with a total follow-up of 2785 person-years, resulting in an incidence density of 8007.18 per 100000 person-years, an average age of onset of (35.90±8.22) years, and an average working age of onset of (2.69±1.97) years. The incidence density in the exposure group was 128.71% higher than that in the control group, and the risk of hypertension in the exposure group was 2.115 times that of the control group. The risk of hypertension was 2.199 times higher for men than for women, 1.344 times higher for those aged 30 and above than for those under 30, 1.546 times higher for smokers than for non-smokers, and 1.750 times higher for drinking workers than for non-drinking ones. The results of Cox proportional hazards regression modeling indicated that the hazard ratio (95%CI) of hypertension among the employees exposed to dust, noise, and carbon monoxide was 2.254 (1.703, 2.982), 1.594 (1.107, 2.295), and 1.567 (1.079, 2.274), respectively, when different covariates (gender, age, smoking, and alcohol consumption) were included. The results of Log-rank test showed that there were statistically significant differences in the distribution of disease-free survival between the exposure group and the control group (P<0.05). Conclusion Occupational exposures to dust, noise, and carbon monoxide may increase the risk of hypertension among calcium carbide plant workers.

Objective To investigate the gene expression profile of cervical exfoliated cells from woman treated by artificial cycle,and their potential association with endometrial receptivity in order to screen specific biomarkers closely related to the receptivity.Methods A total of 19 female patients were enrolled from those preparing for frozen embryo transfer(FET)at the Reproductive Center of First Medical Center of Chinese PLA General Hospital from February 2024 to October 2024.Under the artificial cycle frozen embryo transfer protocol,the endometrial tissues were collected on the 4th day after progesterone administration(P+4)to verify their endometrial receptivity status.Additionally,cervical exfoliated cells were collected on the 4th day(P+4)and the 6th day(P+6)after progesterone administration.RNA sequencing(RNA-Seq)was used to detect gene expression profiles.Differentially expressed genes(DEGs)were identified using the criteria of|log2fold change|＞1 and a false discovery rate(FDR)＜0.05,followed by bioinformatics analysis.The protein-protein interaction(PPI)network of DEGs was constructed using R software(4.4.1)and analyzed with gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)analyses.The candidate genes were identified based on the PPI network using Cytoscape software.Quantitative reverse transcription PCR(RT-qPCR)was employed to validate the target candidate genes both in vitro and in vivo.Results The rsERT confirmed that all 19 women were in state of endometrial receptivity at P+6.RNA-Seq identified 3 458 DEGs in cervical exfoliated cells between P+4 and P+6.The up-regulated DEGs were mainly enriched in the pathways associated with immune response and cell differentiation,and the down-regulated ones were mainly enriched in the pathways associated with lipid metabolism and cell proliferation.Using maximal clique Centrality(MCC)algorithm in the PPI network,the top 20 genes were selected.Among them,6 genes,such as IFIT2,OASL,MX1,RSAD2,IFIT1 and IFIT3,tied for the first place,and the 6 genes all belong to interferon-stimulated genes(ISGs).qRT-PCR indicated that the above 6 genes showed significantly higher expression levels in the cervical exfoliated cells at the P+4 stage than the cells at the P+6 stage(P＜0.05).Conclusion There are changes in the expression levels of the genes related to immunity and cytoskeleton remodeling in cervical exfoliated cells during the endometrial receptivity phase.The decrease in the expression of ISGs may serve as a potential biomarker for endometrial receptivity.

Objective To evaluate the application efficacy of structured symptom intervention program in patients with chronic kidney disease(CKD)during the peri-dialysis period.Methods A non-simultaneous control study was conducted on 151 peri-dialysis outpatients having not yet initiated dialysis and being followed up who were subjected with convenience sampling from Department of Nephrology of Second Affiliated Hospital of Army Medical University from April to September 2024.According to the time period of their visits,the patients who visited from April to June 2024 were assigned into a control group(n=75),and those from July to September 2024 into an experimental group(n=76).The control group received conventional symptom intervention(telephone symptom reporting+health education),while the experimental group received the intervention as the control group and a structured symptom intervention program covering 4 evidence-based modules:symptom identification,assessment,intervention,and outcome.The efficacy of above treatments was evaluated before and at 3 months after intervention.Dialysis symptom index was used to assess the degree of symptom distress and the number of symptoms.MOS 36-Item Short Form Health Survey(SF-36)was employed to evaluate the quality of life.The differences in clinical indicators and endpoint events were compared between the 2 groups after intervention.Results The experimental group obtained more significant reduction in the total score of symptom distress than the control group(P=0.021).After intervention,the number of symptoms was decreased in both groups(P<0.001),but no statistical difference was observed between the groups.The score of mental health dimension in SF-36 was obviously improved in the experimental group(P=0.004),which was notably better than that in the control group(P=0.033).The experimental group exhibited significantly higher prealbumin level than the control group(P=0.019),and stable albumin level,which was significantly decreased in the control group(P=0.035).The incidence of endpoint events was remarkably lower in the experimental group than the control group(P=0.028).Conclusion The structured symptom intervention program implements intervention through a closed-loop symptom module,which can effectively alleviate the symptom distress of patients during the peri-dialysis period,improve mental health and reduce the short-term risk for endpoint events.

Dementia in traditional Chinese medicine （TCM） mainly presents amnesia and dullness. Alzheimer's disease and vascular dementia belong to the category of dementia in TCM. These progressive neurological diseases have a complex etiology and a long course， and the drugs that can reverse the disease course remain to be developed. Therefore， early intervention plays a vital role in delaying the disease progression. Apathy refers to a lack of motivation that leads to the attenuation or disappearance of goal-directed behaviors， cognitive functions， and emotional responses. Clinical studies have suggested that apathy exists in the early stage of a variety of neurodegenerative diseases， being one of the key symptoms to the early diagnosis of dementia. The severity of apathy is related to the severity of dementia. Therefore， early diagnosis and treatment of apathy are of great significance to the prevention and treatment of dementia. The preclinical research on apathy in dementia is still in its infancy， and the systematic evaluation method has not been prescribed. The clinical diagnosis and treatment are also in the exploratory stage， and the complex pathophysiological mechanisms of apathy and dementia development have not been fully elucidated. This article reviews the research progress of apathy in dementia， the apathetic behaviors of dementia animal models， the behaviors of patients with apathy， and the treatment methods in recent years and summarizes the research status of apathy in dementia. This review aims to provide a theoretical basis for exploring the behavior of apathy in dementia and conducting preclinical research and evaluation of the pathogenesis and to lay a foundation for the treatment of apathy in dementia.

Objective To investigate the impact of healthy eating patterns on the mortality rate and in-cidence rates of end-stage kidney disease(ESKD)and cardiovascular disease(CVD)in the patients with chronic kidney disease(CKD)by meta analysis.Methods The studies on the relationship between the dietary patterns on the mortality,and the incidence rates of ESKD and CVD in the patients with CKD were retrieved from PubMed,Embase,Cochrane Library,CNKI,Wanfang Database and VIP Database.The retrieval time was from the database establishment to January 2023.The two researchers independently screened the literatures,ex-tracted the data and conducted the literature quality evaluation.The RevMan5.3 software was used for the meta-analysis of the included literatures.Results A total of 10 studies were included in this study,involving 27 291 patients.The results showed that the mortality(HR=0.70,95％CI:0.57-0.87,Z=3.18,P=0.001)and the ESKD incidence rate(HR=0.80,95％CI:0.71-0.91,Z=3.44,P＜0.001)and CVD inci-dence rate(HR=0.77;95％CI:0.61-0.97,Z=2.21,P=0.003)had statistical differences between the pa-tients with high dietary score and the patients with low dietary score.Conclusion Persisting in the healthy dieta-ry patterns could decrease the mortality rate,and incidence rates of ESKD and CVD in the patients with CKD.

Objective:To measure the retinal structural and functional parameters of adult Macaca fascicularis, and explore the similarity of the retinal structural and functional parameters between non-human primates and normal human retinas.Methods:Six eyes of 3 5-year-old adult Macaca fascicularis were examined by in vivo detection including color fundus photography, retinal optical coherence tomography (OCT) and electroretinogram (ERG) to determine the thickness of the inner/outer retina at the fovea and 1 000/2 000 μm away from the nasal, temporal, superior and inferior regions of the fovea, the thickness of the retinal nerve fiber layer (RNFL), the area of optic disc, the area of optic cup, the area ratio of cup to disc and the biological parameters of flash ERG.Differences in the above parameters between left and right eyes were analyzed.The similarity of parameters between Macaca fascicularis and human was compared with reference to published literature.The use and care of animals complied with the Regulation on the Management of Experimental Animals.The study protocol was approved by the Institutional Animal Care and Use Committee of Hubei Topgene Biotechnology (NO.IACUC-2019-012). Results:The foveal thickness, optic disc area, cup-disc area ratio, and average RNFL thickness in normal adult Macaca fascicularis were (252.31±4.79)μm, (1.89±0.05)mm 2, 0.14±0.01, and (103.53±0.58)μm, respectively.The b-wave amplitude of dark-adapted 0.01 ERG was (66.75±7.29)μV.The a- and b-wave amplitudes of dark-adapted 3.0 ERG response were (57.15±15.01) and (122.10±25.51)μV, respectively.The a- and b-wave amplitudes, the amplitude of oscillation potentials, and the latency of dark-adapted 10.0 ERG response were (72.98±20.14)μV, (131.67±13.78)μV, (49.98±10.08)μV, and (30.02±5.76)ms, respectively.The a- and b-wave amplitudes of light-adapted 3.0 ERG were (9.16±2.75) and (40.43±5.57)μV, respectively.The latency and the amplitude of the light-adapted 30 Hz flicker was (26.61±1.19)ms and (24.72±5.10)μV, respectively.There was no significant difference in the parameters between left and right eyes (all at P>0.05). The retinal thickness in central fovea, mean RNFL thickness, waveform and amplitude of ERG of Macaca fascicularis were similar to normal human. Conclusions:The structure and function of the retina of adult Macaca fascicularis are similar to those of normal humans.As a laboratory animal for preclinical drug research, in vivo studies of Macaca fascicularis can refer to normal human retinal parameters.

Objective To evaluate the efficacy and safety of neoadjuvant arterial interventional chemotherapy(NAIC)and neoadjuvant intravenous chemotherapy(NIVC)for the treatment of locally advanced cervical cancer(LACC).Methods Randomized controlled trials(RCTs)which fit the theme were included by searching PubMed,Web of Science,Embase,CNKI,and Wanfang databases.After study quality assessment and data extraction,statistical analysis was performed using Stata 17.0,and outcome quality was assessed using the GRADE system.Results A total of 14 RCTs were included,with 1 063 LACC patients.The results of the Meta-analysis showed that NAIC and NIVC had a positive effect on the effectiveness indicators:complete response(CR)[RR=1.23,95％CI(0.91,1.67),P=0.174],partial response(PR)[RR=1.10,95％CI(0.86,1.20),P=0.874],total response(TR)[RR=1.10,95％CI(0.95,1.25),P=0.212],no change(NC)[RR=0.62,95％CI(0.33,1.16),P=0.137]and progressive disease(PD)[RR=1.43,95％CI(0.41,4.99),P=0.574]were not statistically significant.Differences in safety indicators:gastrointestinal reactions[RR=0.96,95％CI(0.76,1.23),P=0.755],hepatic and renal impairment[RR=0.71,95％CI(0.41,1.23),P=0.226]were not statistically significant.While in the incidence of myelosuppression[RR=0.62,95％CI(0.45,0.86),P=0.04],NAIC was superior to NIVC.In addition,the GRADE score results showed CR,PR,TR,and NC were high-quality evidence.Conclusion For LACC patients,the incidence of myelosuppression after treatment with NAIV is lower and safer than that with NIVC,and no significant difference was found between the two in terms of other efficacy and safety indicators.Clinicians should choose the appropriate neoadjuvant chemotherapy regimen based on a comprehensive assessment of the patient's actual condition.
