ABSTRACT
Objective To investigate the expression level and diagnostic value of serum DNA polymerase α(DNA pol α)in Alzheimer's disease(AD),and analyze its diagnostic efficacy in AD.Methods A total of 100 patients of dementia of Alzheimer's type(DAT)and 43 patients of mild cognitive impairment(MCI)from Xuanwu Hospital Capital Medical University from March 2019 to April 2023 were included in this study,and 68 healthy individuals of the same age group were collected as the HC group.The expression level of DNA pol α was detected in each group,and the diagnostic value of DNA pol α in AD was analyzed by receiver oper-ating characteristic(ROC)curve.Results The expression level of DNA pol α in DAT group was higher than those in the MCI group(P＜0.05)and the HC group(P＜0.001).The expression level of DNA pol α showed an increasing trend as AD progressed.The expression level of DNA pol α was negatively correlated with Mini Intelligent Mental State Examination Scale(MMSE)score and Montreal Cognitive Assessment Scale(MoCA)score(r=-0.155 3,-0.203 7,P＜0.05).The area under the curve(AUC)of DNA pol α for diagnosing DAT was 0.682,and the sensitivity was 0.900.The AUC for diagnosing MCI was 0.546,and the sensitivity was 0.977.The AUC for differential diagnosis of MCI and DAT was 0.664,the sensitivity was 0.780,and the specificity was 0.535.Conclusion The expression level of DNA pol α is significantly increased in AD patients with DAT,and its expression level is related to the progression of AD,suggesting that DNA pol α has the pos-sibility to be a potential blood biomarker for the diagnosis of AD.
ABSTRACT
Abstact:Objective To investigate the gene expression differences between left-sided colon cancer and right-sided colon cancer and the mechanism differences between the colorectal cancer core drug pairs of Sophorae Flavescentis Radix-Sargentodoxae Caulis-Scutellariae Barbatae Herba acting on left-sided and right-sided colon cancer.Methods The transcriptome data of 134 patients with left-sided colon cancer and 194 patients with right-sided colon cancer from The Cancer Genome Atlas(TCGA)were downloaded,and the R software was applied to realize the differential gene analysis of the two groups and the enrichment analysis of Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway;the BATMAN-TCM database was used to obtain the active ingredients and targets of the drug pair of Sophorae Flavescentis Radix-Sargentodoxae Caulis-Scutellariae Barbatae Herba,and based on the different genes of the left-and right-sided colon cancers,KEGG enrichment analysis of the drug pair-left/right-sided colon cancers was performed respectively,and the protein-protein-interaction(PPI)network was constructed to compare the differences of the biosignaling pathways enriched by the drug pairs for the treatment of left-and right-sided colon cancers,as well as the differences of the key target points.Results There were 6 051 differentially expressed genes common to left-and right-sided colon cancers relative to normal paracancerous tissues,1958 differentially expressed genes specific to left-sided colon cancer,and 1739 differentially expressed genes specific to right-sided colon cancer;14 KEGG-enriched pathways specific to left-sided colon cancer,and 23 KEGG-enriched pathways specific to right-sided colon cancer.There were 85 active compounds in the drug-pair of Sophorae Flavescentis Radix-Sargentodoxae Caulis-Scutellariae Barbatae Herba,corresponding to a total of 469 targets.The drug-pair-left-sided colon cancer targets were enriched in 10 KEGG signaling pathways,with the key targets being DRD2,CACNA1C,HTR3A,COMT,and TH;and the drug-pair-right-sided colon cancer targets were enriched in 1 KEGG signaling pathway,with the core targets being HTR3A,DRD2 TH,AGT,GRIN2B.Conclusion There are gene expression differences between left-and right-sided colon cancers:left-sided colon cancer is associated with abnormal immune function,abnormal AMPK signaling pathway and other mechanisms,and right-sided colon cancer is associated with neutrophil extracellular trap formation,alcoholism,abnormal Hippo signaling pathway and other mechanisms.In addition to regulating cell cycle and essential amino acid metabolism and other mechanisms,Sophorae Flavescentis Radix-Sargentodoxae Caulis-Scutellariae Barbatae Herba drug pairs have specific effects on regulating the intestinal endocrine function of the left-sided colon cancer,inhibiting inflammatory response of the right-sided colon cancer,and may also have mood-regulating effects on patients with colon cancer.
ABSTRACT
Objective:Migraine and tremor share some genetic mutation sites,and clinical studies have also confirmed their correlation.This study aims to explore the clinical and electrophysiological characteristics of migraine patients with concomitant tremor,and to analyze the relevant influential factors of tremor occurrence. Methods:We retrospectively analyzed the clinical data of 217 migraine patients who visited the Third Affiliated Hospital of Qiqihar Medical University from June 2022 to October 2023.The Clinical Rating Scale for Tremor(CRST),Numerical Rating Scale(NRS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9)were respectively used to assess the tremor symptoms,degree of headache,anxiety,and depression of patients.All patients underwent routine head MR scanning and electromyography examination,and were divided into a migraine with tremor group and a migraine without tremor group based on the electromyogram examination. Results:The migraine with tremor group and the migraine without tremor group were included 52 patients(23.96%)and 165 patients(76.04%),respectively.Compared with the migraine without tremor group,the migraine with tremor group had a longer course and duration of headache,higher frequency of headache attacks,higher NRS score,GAD-7 score,and PHQ-9 score,and fewer weekly physical exercises.The differences were statistically significant(all P<0.05).There were no statistically significant differences in the presence or absence of prodromal headache and white matter hyperintensities(WMHs)between the 2 groups(both P>0.05).The evaluation results of the CRST showed that out of 217 migraine patients,39 patients(17.97%)were accompanied by tremors.The electromyographic results showed that all 52 migraine patients with tremors had upper limb tremors,including 28 migraine patients with postural tremors and 24 migraine patients with static tremors.Compared with the migraine patients with static tremors,the migraine patients with postural tremors had lower average frequency,peak frequency,and headache onset frequency(all P<0.05).Multiple linear regression analysis showed that frequency of physical exercise,duration of illness,frequency of headache attacks,NRS score,GAD-7 score,and PHQ-9 score were risk factors for migraine patients with concomitant tremors(all P<0.05). Conclusion:Patients with migraine mainly experience upper limb postural tremors.Reduced physical exercise,long course of disease,long duration of headache,frequent headache attacks,severe headache,anxiety,and depression are risk factors for migraine patients with concomitant tremors.
ABSTRACT
Objective To summarize the aortographic features of child patients with Kawasaki disease(KD)complicated by coronary artery lesion(CAL)who were treated at the Wuhan Children's Hospital of China.Methods The clinical data of 30 child patients with early recovery stage KD complicated by CAL,who received aortic angiography examination at Wuhan Children's Hospital of China between June 2016 and June 2023,were retrospectively analyzed.Preoperative echocardiography was adopted to evaluate the severity of CAL,and aortic angiography under laryngeal mask general anesthesia was performed.Results Successful aortic angiography examination was accomplished in all the 30 child patients with KD complicated by CAL.After angiography,the CAL risk classification results showed that grade I was seen in 5,grade Ⅱ in 7,grade Ⅲ in 12,grade Ⅲ in 4,and grade V in 2 child patients.Of all child patients,old coronary thrombosis was found in one(grade Ⅲb),and coronary artery stenosis with collateral circulation formation in one(grade Ⅴ).The CAL was located at the proximal segment(n=15),middle segment(n=3)and distal segment(n=2)of the right coronary artery,at the left main coronary artery(n=12),and at the proximal segment of left coronary artery anterior descending branch(n=9).Electrocardiography showed sinus rhythm(n=17),sinus arrhythmia(n=4),right bundle branch block(n=4),atrial premature beat(n=1),ventricular premature beat(n=2),T-wave change(n=1),and Q-wave change(n=1,coronary lesion grade V,echocardiography suggested left heart enlargement).No cardiac enlargement,cardiac functional insufficiency,or valvular regurgitation signs were observed in the remaining child patients.Conclusion It is clinically safe and feasible to perform aortic angiography examination in child patients with early recovery stage KD complicated by CAL.In this series of child patients with KD,CAL mainly occurs at the proximal segment of coronary artery,especially at the proximal segment of right coronary artery as well as at the left main artery and left anterior descending branch.
ABSTRACT
Objective:To study the effects of endoplasmic reticulum stress (ERS) and autophagy mechanisms in the pathogenesis of necrotizing enterocolitis (NEC).Methods:A total of 39 newborn SD rats were randomly assigned into 3 groups: the NEC group (NEC model: artificial feeding+hypoxic stimulation+intragastric injection of lipopolysaccharides), the ERS antagonist group (NEC model+intraperitoneal injection of 4-phenylbutyric acid) and the ERS inducer group (NEC model+intraperitoneal injection of tunicamycin). After successful modeling, the rats were sacrificed and intestinal tissues were obtained. The intestinal pathology was observed using electronic microscope. Intestinal fatty acid binding protein (I-FABP) was detected using ELISA. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to examine mRNA levels of glucose-regulated protein 78 (GRP78) and oxygen-regulated protein 150 (ORP150). Western-blot was used to detect p62 and autophagy-related proteins (microtubule-associated protein 1 light chain 3 (LC3)Ⅱ and LC3Ⅰ) and LC3Ⅱ/LC3Ⅰ ratio was calculated.Results:(1) For all 3 groups, the pathological scores of rat intestines were≥2. (2) The ERS inducer group showed significantly higher clinical score, pathological score, I-FABP level, GRP78 and ORP150 mRNA levels and LC3Ⅱ/ LC3Ⅰ ratio than the NEC group and ERS antagonist group, and the NEC group higher than the ERS antagonist group ( P<0.05). The p62 level in the ERS inducer group was significantly lower than the NEC group and the ERS antagonist group, and the NEC group lower than the ERS antagonist group ( P<0.05). (3) The LC3Ⅱ/ LC3Ⅰ ratio was positively correlated with clinical score, pathological score and I-FABP level ( P<0.05). The p62 level was negatively correlated with clinical score, pathological score and I-FABP level ( P<0.05). The mRNA levels of GRP78 and ORP150 were positively correlated with clinical score, pathological score and I-FABP level ( P<0.05). LC3Ⅱ/ LC3Ⅰ ratio was positively correlated with the mRNA levels of GRP78 and ORP150 ( P<0.05). The p62 level was negatively correlated with the mRNA levels of GRP78 and ORP150 ( P<0.05). Conclusions:ERS is associated with the pathogenesis of NEC. Inhibition of ERS can reduce autophagy and improve intestinal barrier function and clinical symptoms of NEC.

Compared with the control group, the observation group had a significantly higher total score of the six-dimension scale of nursing performance and significantly higher scores of each dimension ( P<0.05). Compared with the control group, the observation group had a significantly higher total score of the self-rating scale of self-directed learning and significantly higher scores of the dimensions of learning awareness, learning behavior, learning strategies, and learning evaluation ( P<0.05). Compared with the control group, the observation group had a significantly higher total score of satisfaction with teaching and significantly higher scores of each dimension ( P<0.05). Conclusions:The combination of the 5E teaching model and flipped classroom is suitable for the standardized training of emergency nurses and can help to improve their clinical nursing ability and self-directed learning ability, with a relatively high degree of satisfaction with teaching.
ABSTRACT
The prevalence of diabetes mellitus in China has recently been increasing year by year,and spontaneous skin ulcers in diabetic patients,as one of the most serious complications,often develop on the patient's extremities represented by foot ulcers.Due to the complexity and variety of its pathogenesis,it leads to poor clinical outcomes and difficulty in healing.Thus,pa-tients often face the risk of amputation and death.Therefore,the exploration of mechanisms of the vascular pathogenesis of diabetic delayed-healing wounds and targeted screening of therapeutic agents has become a current research hotspot.Herein,in this paper,we briefly review the role of impaired angiogenesis and vascular dysfunction in diabetic skin ulcers,and the research progress of classical hypoglycemic and natural compounds against vascular lesions is preliminarily summarized to provide a theoretical basis for effective clinical treatment.
ABSTRACT
Objective To explore the clinical significance and antimicrobial resistance of group B Streptococcus(GBS)isolated from midstream urine culture,aiming to provide a basis for the diagnosis and treatment of clinical urinary tract infection(UTI).Methods Information about GBS strains isolated from midstream urine culture of in-patients and outpatient in a hospital in Nanjing from February 2020 to December 2022 were retrieved through labora-tory information system,strains with complete data were screened out.Case data,urine routine,and antimicrobial susceptibility testing results were reviewed.Results A total of 9 081 non-repetitive bacterial strains were detected from midstream urine culture,including 425 GBS strains,accounting for 4.7％,ranking sixth.Strains with incom-plete data were excluded,a total of 365 patients were included in the study.169(46.3％)were males and 196(53.7％)were females,with an average age of(55.4±15.2)years.365 patients who were detected GBS were from 17 de-partments,with the highest proportion being department of urology(n=237,64.9％).The underlying diseases of patients mainly included hypertension(n=136),diabetes(n=95),urolithiasis(n=120)and urinary tumors(n=98).211 patients underwent urological surgery,all were treated with antimicrobial agents before surgery,and 205 patients underwent indwelling urinary catheters after surgery;9 patients were detected GBS from urine during the middle and advanced stage of pregnancy.36.4％(n=133),38.9％(n=142)and 24.7％(n=90)patients had GBS colony count ≤104 CFU/mL,104-105 CFU/mL,and ≥105 CFU/mL,respectively.Patients with symptoms of UTI accounted for 24.9％(n=91),and asymptomatic bacteriuria accounted for 75.1％(n=274).The incidence of UTI symptoms in males was lower than that in females(19.5％vs 29.6％,P＜0.05).As the GBS colony count in urine culture increased,the proportion of patients with symptoms of UTI showed an upward trend(P＜0.05).On the day of urine culture,the positive rates of urine routine white blood cells,leukocyte esterase,and nitrite were 53.2％,50.1％,and 3.8％,respectively.The positive rates of urine occult blood,leukocyte esterase,white blood cells,and urine protein in patients with symptomatic UTI were all higher than those with asymptomatic bacteriuria patients(all P＜0.05).No GBS were found to be resistant to penicillin,ampicillin,vancomycin,linezolid,and tigecycline.The resistance rate to levofloxacin and moxifloxacin was about 40％,and resistance rate to tetracycline and clindamycin was over 60％.Conclusion GBS isolated from urine is more common in non-pregnant adults,and only a small percentage have symptoms of UTI.The results of urine culture and urine routine should be comprehen-sively judged based on patient's clinical symptoms and signs.GBS in urine is susceptible to multiple antimicrobial agents,and clinical medication should be adopted rationally based on antimicrobial susceptibility testing result.
ABSTRACT
Objective To investigate the implementation of surveillance,prevention and control measures for healthcare-associated infection(HAI)in maternal and child healthcare(MCH)institutions,and provide policy evi-dence for optimizing HAI prevention and control in MCH institutions.Methods Stratified sampling was conducted among the MCH institutions at provincial,municipal and county levels in 8 provinces/autonomous regions.A uni-fied questionnaire was designed and the online survey was conducted through"Questionnaire Star".Results The data from 123 MCH institutions were included in the analysis.90.24％of the MCH institutions carried out compre-hensive surveillance on HAI.The ratios of MCH institutions which implemented targeted surveillance on HAI in neonatal intensive care unit(NICU),surgical site infection,multidrug-resistant organisms(MDROs)and HAI in intensive care units(non-NICU excluded)were 89.66％,85.96％,80.77％,and 74.19％,respectively.51.22％MCH institutions adopted information surveillance system on HAI cases.94.31％MCH institutions carried out surveillance on hand hygiene compliance.Over 90％MCH institutions carried out surveillance on environment hy-giene in high-risk departments.71.54％MCH institutions conducted centralized cleaning,disinfection,sterilization and supply for reusable medical instruments in the central sterile supply department(CSSD).Over 90％MCH insti-tutions established three-level pre-examination triage systems.86.18％set up transitional wards.MCH institutions generally adopted a management model with established effective communication,full appointment visits,and sepa-rate visits for special medical groups,such as registered pregnant women,high-risk newborns,healthcare groups,and long-term rehabilitation patients.However,the ratio of institutions conducting on-line follow-up visits was less than 50％.Conclusion MCH institutions have generally carried out comprehensive and targeted surveillance on HAI.Information surveillance need to be facilitated.Hand hygiene and environmental hygiene surveillance has been popularized to a certain extent at all levels of MCH institutions.The cleaning,disinfection,sterilization,and supply processes of reusable medical devices in a few MCH institutions are not standardized.Special medical populations get effective management.On-line healthcare is to be further promoted.

ABSTRACT
Objective To explore specific magnetic resonance imaging(MRI)features of somatic symptoms in depression by comparing the differences of brain gray matter volume in depression patients with and without somatic symptoms using voxel-based morphometry(VBM).Methods A total of 52 depression patients were recruited and divided into somatic and no somatic symptoms group according to the patient health questionnaire-15 score(＞9 and≤9,respectively).Forty gender-age-matched healthy volunteers were recruited as the control group.All subjects underwent MRI scanning.Imaging data were analyzed to explore the differences in brain gray matter between groups using VBM.Results Compared with control group,gray matter volume increased in the right superior temporal gyrus,and decreased in the right inferior orbitofrontal gyrus,right inferior temporal gyrus,left inferior orbitofrontal gyrus,and left superior temporal gyrus for depressive patients with somatic symptoms(P＜0.001);gray matter volume increased in the right middle temporal gyrus,and decreased in the right superior temporal gyrus and right inferior temporal gyrus for depressive patients without somatic symptoms(P＜0.001).Only the volume in the right tongue and left cingulate gyrus increased in depressive patients with somatic symptoms compared with that in patients without somatic symptoms(P＜0.01).Conclusion VBM-MRI has demonstrated increased volume in the tongue and cingulate gyrus in the somatic symptoms of depression.
ABSTRACT
Non-suicidal self-injury is a prevalent pathological behavior in clinical settings,significantly impacting both physical and mental health.Non-suicidal self-injury is closely associated with the abnormal perception of pain.Pain can be classified as physiological pain and social pain.In contrast to healthy people,individuals engaging in non-suicidal self-harm exhibit lower sensitivity to physiological pain but higher sensitivity to social pain.Their physiological pain thresholds are elevated,while their social pain thresholds are reduced.The alterations in pain sensitivity led them to alleviate emotions through a"pain to counter pain"approach.The abnormalities in pain sensitivity among individuals who engage in non-suicidal self-injury are closely linked to their social and psychological factors.Self-criticism,depressive symptoms,and adverse childhood experiences are all associated with the pain sensitivity of non-suicidal self-harm patients.

ABSTRACT
Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis worldwide, characterized by the deposition of IgA in the mesangial area of the glomerulus. At present, the pathogenesis of IgAN is not yet clear, and there has been a lack of specific and recognized treatment plans. In recent years, many domestic and foreign researchers have conducted research on important pathways and key molecules in its pathogenesis, aiming to explore new therapeutic drugs. This review mainly summarizes the latest progress in the treatment of IgAN, including drugs that have been proven effective against IgAN and drugs that are currently being evaluated in clinical studies.
ABSTRACT
Objective:To study the effect of gauze filtration on the content of adipose stem cells in fat gel.Methods:In March 2022, fat samples from 5 patients who underwent abdominal fat aspiration at the Hunan Provincial People′s Hospital were collected, prepared fat ged, the fat gel was filtered 1-5 times with 2 layers of gauze, and the amount of fat gel passing through a 1 ml threaded syringe with a 27 G needle was measured after each filtration. At the same time, the content of fat stem cells in the filtered fat gel was detected by flow cytometry.Results:As the number of filters increases, the amount of fat gel passing through gradually increased. The increasing trend was obvious after the first to fourth filters, and the increasing trend slowed down after the fifth filter. After statistical analysis, the differences between the first filter and the second filter, the second filter and the third filter, and the third filter and the fourth filter were statistically significant ( P<0.05). There was no statistically significant difference between the fourth filter and the fifth filter ( P>0.05). As the number of filters increased, the content of adipose stem cells in the fat gel gradually decreased. The decreasing trend was obvious after the first to third filters, and the decreasing trend slowed down after the fourth filter. After statistical analysis, the differences between the first filter and the second filter, as well as the second filter and the third filter, were statistically significant (all P<0.05). However, there was no statistically significant difference between the third filter and the fourth filter, and the fourth filter and the fifth filter (all P>0.05). Conclusions:The more times gauze is filtered, the better the permeability of fat gel. However, the content of adipose stem cells will significantly decrease in the first three filters. Therefore, the number of times gauze is filtered for fat gel should be minimized as much as possible.
ABSTRACT
Objective To analyze the structural changes and reasons for hospitalization expenditure among patients with thyroid cancer,so as to provide a reference basis for reasonable control of medical costs,making the structure of hospitalisation costs for patients undergoing surgery for thyroid cancer more rational.Methods The degree of structural change and the grey correlation method were used to quantitatively analyze the changes in the structure of hospitalization expenses and the degree of correlation of patients with thyroid cancer surgery in a hospital in Shanxi Province from 2017 to 2022.Results From 2017 to 2022,the hospitalization expenses of thyroid cancer surgery patients in the hospital showed a decreasing trend,and drug fees and consumables fees accounted for a large proportion.Consumables fees and treatment fees showed positive contribution changes,drug fees and diagnosis fees showed negative contribution changes.Nursing fees and general medical service fees showed positive contribution changes,but were not obvious.During the 6-year period,the top two related factors affecting the hospitalization expenses of thyroid cancer patients were drug fees and consumables fees.Conclusion The structure of hospitalization expenses of per thyroid cancer patients tends to be reasonable,but there is still a large room for improvement.It is suggested to continue to strengthen the control of drugs and medical consumables,and clarify the value composition of technical labor and material consumables,so as to further optimize the structure of hospitalization expenses.
