Objective:To investigate the correlation between the single nucleotide polymorphism (SNP) of the PLCE1 gene and children with primary nephrotic syndrome (PNS) in Guangxi Zhuang Autonomous Region. Methods:This study was a retrospective study, a case-control study was used to select 155 cases of PNS in Guangxi Zhuang children attending the Affiliated Hospital of Youjiang Medical University for Nationalities from January 2017 to January 2021 (PNS group), and 100 healthy Guangxi Zhuang children who were physically examined during the same period (healthy control group). Genotyping of PLCE1 SNP rs3765524, and rs2274223 were performed using the second-generation gene sequencing technology, and their correlation with the development of PNS was analyzed. Logistic regression analysis was used for correlation analysis, and Chi- square test or Fisher′ s exact probability method was used for comparison between groups. Results:(1)Compared with the healthy control group, PLCE1 rs3765524 was correlated with the risk of PNS in children of PNS group, and the TT genotype may reduce the risk of PNS in the co-dominant model ( OR=0.435, 95% CI: 0.238-0.794, P=0.007). There were no significant differences in the genotype of PLCE1 rs2274223 and the frequency of allele distribution between PNS group and healthy control group (all P>0.05). (2) A strong linkage disequilibrium existed at PLCE1 SNP rs3765524 and rs2274223.(3) There were no significant differences in the frequency of the distribution of haplotypes AC, AT and GT between PNS group and healthy control group (all P>0.05). Conclusions:PLCE1 SNP rs3765524 is correlated with the risk of PNS in children in Guangxi Zhuang Autonomous Region, and the TT genotype may be a protective factor for PNS in children in Guangxi Zhuang Autonomous Region.

Establishment and preliminary evaluation of a fluorescent recombinase-aided amplification/CRISPR-Cas12a system for rapid detection of Plasmodium falciparum / 中国血吸虫病防治杂志

Objective To establish a fluorescent assay for rapid detection of Plasmodium falciparum based on recombinaseaided amplification (RAA) and CRISPR-Cas12a system,and to preliminarily evaluate the diagnostic efficiency of this system.. Methods The 18S ribosomal RNA (rRNA) gene of P. falciparum was selected as the target sequence, and three pairs of RAA primers and CRISPR-derived RNA (crRNA) were designed and synthesized. The optimal combination of RAA primers and crRNA was screened and the reaction conditions of the system were optimized to create a fluorescent RAA/CRISPR-Cas12a system. The plasmid containing 18S rRNA gene of the P. falciparum strain 3D7 was generated, and diluted into concentrations of 1 000, 100, 10, 1 copy/μL for the fluorescent RAA/CRISPR-Cas12a assay, and its sensitivity was evaluated. The genomic DNA from P. vivax, P. malariae, P. ovum, hepatitis B virus, human immunodeficiency virus and Treponema pallidum was employed as templates for the fluorescent RAA/CRISPR-Cas12a assay, and its specificity was evaluated. Fifty malaria clinical samples were subjected to the fluorescent RAA/CRISPR-Cas12a assay and nested PCR assay, and the consistency between two assays was compared. In addition, P. falciparum strain 3D7 was cultured in vitro. Then, the culture was diluted into blood samples with parasite densities of 1 000, 500, 200, 50, 10 parasites/μL with healthy volunteers’ O-positive red blood cells for the RAA/CRISPR-Cas12a assay, and the detection efficiency was tested. Results The Pf-F3/Pf-R3/crRNA2 combination, 2.5 μL as the addition amount of B buffer, 40 min as the RAA reaction time, 37 °C as the reaction temperature of the CRISPR-Cas12a system were employed to establish the fluorescent RAA/CRISPR-Cas12a system. Such a system was effective to detect the plasmid containing 18S rRNA gene of the P. falciparum strain 3D7 at a concentration of 1 copy/μL, and presented fluorescent signals for detection of P. falciparum, but failed to detect P. ovum, P. malariae, P. vivax, T. pallidum, hepatitis B virus or human immunodeficiency virus. The fluorescent RAA/CRISPR-Cas12a system and nested PCR assay showed completely consistent results for detection of 50 malaria clinical samples (kappa = 1.0, P < 0.001). Following 6-day in vitro culture of the P. falciparum strain 3D7, 10 mL cultures were generated and the fluorescent RAA/CRISPR-Cas12a system showed the minimal detection limit of 50 parasites/μL. Conclusion The fluorescent RAA/CRISPR-Cas12a system is rapid, sensitive and specific for detection of P. falciparum, which shows promising value for rapid detection and risk monitoring of P. falciparum.

Awareness of diabetes knowledge and its influencing factors among health examination population / 中华健康管理学杂志

Objective:To investigate the awareness of diabetes knowledge among the health examination population and its influencing factors.Methods:A cross-sectional study. From september to november 2022, the subjects of six health examination centers located in six different cities (Beijing, Shanghai, Tianjin, Chongqing, Xiamen, Hangzhou) in China were investigated in the form of questionnaires to investigate the awareness of diabetes core information and the level of trust to different information sources of diabetes knowledge. According to the questionnaire results, the subjects were divided into a high awareness group of diabetes core information and a low awareness group. Logistic regression was used to analyze the influencing factors of diabetes core information awareness; the t-test was used to compare the trust degree of the two groups to different information sources. Results:A total of 9 315 people were included in the six centers, including 4 932 men (52.90%) with an average age of (39.36±12.64) years and 4 383 women (47.10%) with a mean age of (37.47±11.85) years. Only 36% of the people had high awareness of diabetes core information; variables such as gender, age, education level, physical examination frequency in the past three years, package price of this physical examination, self-evaluation of diabetes knowledge, diabetes status, and city of residence were variables that affect the level of awareness of core information related to diabetes (all P<0.05). Compared with the low awareness group of diabetes core information, the high awareness group trusted professional medical staff ( t=-9.597, P<0.05) and community health promotion more ( t=-5.014, P<0.05), but did not trust the emerging popular science propaganda means, such as WeChat official accounts/WeChat groups/QQ groups, Internet web page, Tiktok/Kwai and other short video APPs. Conclusion:The awareness rate of diabetes knowledge among the health examination population is low, and it is affected by many factors; Health education on diabetes knowledge should be carried out for people undergoing physical examination.

Objective To observe the risk factors of in-hospital mortality in patients with acute myocardial infarction complicated with cardiogenic shock after primary percutaneous coronary intervention (PCI).Methods Totally 111 cases of acute myocardial infarction complicated with cardiogenic shock received acute PCI from 2009 to 2015 in Beijing Anzhen Hospital were enrolled.The cases were divided into the in-hospital death group (31 cases) and the in-hospital survival group (80 cases).The general information,clinical indicators,range of myocardial infarction,coronary lesions and management,complications,drug treatment and equipment assistance of the two groups were compared,and logistic regression analysis was used to analyze the risk factors of in-hospital mortality.Results The proportions of age ≥ 75 years,hyperlipidemia,serum creatinine ＞ 110 μmol/L,LVEF ＜ 40％,anterior myocardial infarction,three-vessel lesions of coronary artery,post-PCI TIMI flow grade ＜3,acute liver injury and acute kidney injury in the in-hospital death group were significantly higher than those in the in-hospital survival group (P ＜ 0.05).The proportion of IABP used in the in-hospital death group was significantly higher than that in the in-hospital survival group (P ＜ 0.05).There were no significant differences in the distribution of culprit lesion and the treatment of stenoses in nonculprit arteries between the two groups (P ＞ 0.05).Multivariate logistic regression analysis showed that age ≥ 75 years,threevessel coronary lesions,post-PCI TIMI flow grade ＜3 and acute renal injury were independent risk factors for hospital mortality (P ＜ 0.05).Conclusions Age ≥ 75 years,three-vessel lesions of coronary artery,post-PCI TIMI flow grade ＜3 and acute kidney injury were independent risk factors of in-hospital death in patients with acute myocardial infarction complicated with cardiogenic shock after primary PCI.

Clinical application of barium radiography and computed tomography-based short-term outcome evaluation criteria in esophageal cancer / 中华放射肿瘤学杂志

Objective To explore and improve the feasibility and prognostic value of barium radiography and computed tomography (CT)-based evaluation criteria in evaluation of the short-term efficacy of radiotherapy for esophageal cancer,and to provide a basis for clinical application.Methods The short-term treatment outcomes of 529 patients with esophageal carcinoma receiving three-dimensional radiotherapy from 2004 to 2015 were evaluated by the 2013 version of barium radiography and CT-based evaluation criteria.The local control (LC) and survival rates were calculated using the Kaplan-Meier method.The log-rank test was used for data analysis and univariate prognostic analysis.The agreement between two evaluation criteria was measured by the Kappa coefficient.Results According to the results of the survival analysis in all the patients using the evaluation criteria for short-term treatment outcomes,the 3-,5-,7-,and 9-year LC rates were 78.6％,69.8％,69.8％,and 63.4％ in the complete response (CR) group (n=52),and 56.4％,47.9％,46.2％,and 42.4％ in the partial response (PR) group (n=409),respectively;the 3-,5-,7-,and 9-year overall survival (OS) rates were 62.7％,49.1％,39.8％,and 39.8％ in the CR group,and 29.5％,21.6％,20.6％,and 19.5％ in the PR group,respectively;the median OS time was 50,17,and 5 months in the CR group,PR group,and non-response group (n=12),respectively (P=0.000).According to CT measurements,the short diameter of residual metastatic lymph node after radiotherapy was between 0.37-3.40 cm (median value=0.82 em).All patients were divided into groups based on the short diameter of residual metastatic lymph node after radiotherapy with a gradient of 0.5 cm.Patients with short diameters of residual metastatic lymph node of ≤ 1.00 cm had a significantly higher OS rate than those with short diameters of residual metastatic lymph node of＞ 1.00 cm (P =0.000).The lymph node volume of 1.00 cm3 in the original criteria was replaced by the short diameter of residual metastatic lymph node of 1.00 cm after radiotherapy and treatment outcomes were re-evaluated using the new criteria.The CR group still had significantly higher LC and OS rates than the PR group (P=0.000).There was a good agreement between the two evaluation criteria (Kappa =0.863).Conclusions The barium radiography and CT-based evaluation criteria for short-term treatment outcomes can accurately evaluate the short-term outcomes and predict prognosis in patients with esophageal carcinoma.Replacing the volume in the original criteria with the short diameter of residual metastatic lymph node after radiotherapy achieves similar results in prognostic prediction.

Association between the accumulation of metabolic syndrome abnormal components and arterial pulse wave velocity among adult individuals undergoing routine health examination / 中华心血管病杂志

Objective@#To explore the association between the accumulation of metabolic syndrome (MS) components and abnormal brachial ankle pulse wave velocity (baPWV), and to investigate the effect of accumulation of abnormal metabolic components on abnormal baPWV among adult individuals undergoing routine health examination.@*Methods@#It's a cross-sectional study. Data from 9 201 stratified sampled subjects, aged between 25 to 75 years old, who took part in the annual health checkups in 11 cities of Zhejiang Province from January to December 2016, were analyzed. Blood pressure(BP), fasting plasma glucose(FPG), waist circumference(WC), triglyceride(TG), high-density lipoprotein cholesterols(HDL-C) were defined as MS components. The baPWV was measured by VP-1000 (BP-203RPE Ⅲ) and ΔbaPWV (measured baPWV-reference baPWV/reference baPWV) ×100 (%)> 10% was defined as abnormal. The relationship between MS components and ΔbaPWV was analyzed by linear regression, and impact of accumulation of MS components on ΔbaPWV was analyzed by logistic regression, and the ΔbaPWV in subjects with different levels of MS components were analyzed by analysis of variance.@*Results@#(1) The linear regression analysis demonstrated a positive correlation between ΔbaPWV and MS components including systolic blood pressure, diastolic blood pressure, WC, FPG, TG, while ΔbaPWV was negatively correlated with HDL-C. The β values were 0.518, 0.616, 0.208, 2.778, 1.862, -1.339, respectively (all P<0.001), indicating a strong association between ΔbaPWV and systolic blood pressure, diastolic blood pressure, and FPG. (2) The logistic regression analysis showed that the proportion of abnormal ΔbaPWV was 2.595 times higher in MS individuals than in non-MS individuals (P<0.001). Abnormal ΔbaPWV increased in proportion with increase in numbers of the metabolic components (OR=1.913, 2.884, 3.833, 6.161, 11.176 in individuals with 1,2,3,4,5 metabolic components, respectively, all P<0.001). (3) The logistic analysis suggested that each component of MS could affect baPWV,and OR was 4.68, 2.45 for systolic blood pressure and/or diastolic blood pressure and FPG. All combinations of 2 components of MS also significantly affected baPWV,and OR value was the highest (5.104(95%CI 4.281-6.085), P<0.001) for FPG+BP. All combinations of 3 components of MS significantly affected baPWV,and OR value was the highest(5.385(95%CI 4.245-6.831), P<0.001) for BP+FPG+TG. All combinations of 4 components of MS affected baPWV,and OR value was the highest (6.519(95%CI 4.731-8.984), P<0.001) for BP+FPG+WC+TG. (4) Finally, every component of MS was divided into 3 levels, their impact on abnormal ΔbaPWV was analyzed. Prevalence of abnormal ΔbaPWV significantly increased with the increasing levels of the metabolic components expect for HDL-C, the F values were 1 224.66, 832.89, 192.72, 112.79 and 56.22, respectively (all P<0.001), indicating that higher levels of metabolic components significantly affected the ΔbaPWV.@*Conclusions@#MS and accumulation of abnormal MS components are closely related with abnormal ΔbaPWV, and the combination of BP and FPG have the greatest impact on the abnormal ΔbaPWV. Analysis on the accumulation of MS components might serve as an early indicator of arteriosclerosis.

Analysis of types and metabolic profiles of hyperphenylalaninemia / 中华实用儿科临床杂志

Objective To study the characteristics of hyperphenylalaninemia (HPA) and the differences in blood and urine metabolic index and their correlation.Methods A total of 137 patients with HPA diagnosed by the Pediatric Inherit Metabolism and Endocrine Department,Guangdong Women and Children's Hospital,Guangzhou Medical University from January 2014 to June 2017,were enrolled.Tandem mass spectrometry (MS/MS),gas chromatography/ mass spectrometry (GC-MS) and high performance liquid chromatography (HPLC) were used to analyze the concentration of blood and urine metabolites in children,and the patients were divided into different groups according to the drug load test of tetrahydrobiopterin (BH4) and dihydrobiopterindine reductase (DHPR) deficiency.The HPA metabolite analysis of horizontal concentration by statistical differences and correlation analysis were performed.Results Among the 137 cases of HPA,there were 101 cases (73.7％) of phenylalanine hydroxylase deficiency (PAH),and among them 21 cases (15.3％) were classic phenylketonuria (PKU),37 cases were mild PKU (27.0％),43 cases (31.4％) wcrc mild HPA.Thcrc were 22 cases (16.1％) with BH4 reaction,and 79 cases (57.7％) of non-reactive type.Besides,there were 36 cases (26.3％) of tetrahydrobiopterin deficiency (BH4 D),of which 6-pyruvoyl tetrahydropterin synthase deficiency (PTPS) in 34 cases (24.8％) and dihydrobiopterindine reductase deficiency (DHPR) in 2 cases (1.5％).Urinary phenylacetic acid (r =0.673,P ＜ 0.01),phenyllactic acid (r =0.736,P ＜ 0.01),phenylpyruvic acid (r =0.642,P ＜ 0.01) were significantly correlated with blood phenylalanine (Phe) concentration,and the neopterin (N) (r =0.442,P ＜ 0.01) and biopterin (B) (r =0.398,P ＜ 0.01) had low correlation.Urinary phenylacetic acid,phenyllactic acid and phenylpyruvic acid had no correlation with urinary pterin.There were significant differences among PTPS deficiency group,BH4 response type,and non-reactive type(all P ＜ 0.05),but no significant difference between the BH4 reaction type and the non-reactive group (P ＞ 0.05).Conclusions Through the analysis of the different types of HPA metabolic profiles,it can help to master the incidence and characteristics in the region,within a certain concentration range of blood Phe,the phenylacetic acid,phenyllactic acid,phenylpyruvic acid should not be tested by GC-MS alone.Uterine erythropoietin analysis of BH4D classification and identification of BH4 reaction,non-reactive PKU have a supporting role,so master the metabolic index of various types of concentration and relevance of HPA,it can provide basis for early diagnosis,accurate treatment and follow-up.

Predictive value of IABP SHOCK Ⅱ risk score on in-hospital mortality of patients with cardiogenic shock after ST segment elevation myocardial infarction / 中华急诊医学杂志

Objective To evaluate the predictive value of IABP SHOCK Ⅱ risk score in in-hospital mortality of patients with ST segment elevation myocardial infarction complicated with cardiogenic shock (CS). Methods From August 2011 to August 2013, the clinical data of 89 patients with cardiogenic shock after STEMI treated with primary PCI and then supported by using IABP were retrospectively analyzed. The IABP SHOCK Ⅱ risk score were calculated from the data at admission and primary PCI. Comparisons of general information, medication and intervention, pre/post IABP vital life signs and in-hospital death were carried out among patients with different risk stratifications. Results The area under ROC curve of risk stratification was 0.723. The patients were categorized into low risk group (score 0-2, n=71) and intermediate-high risk group (score 3-9, n=18).The patients in intermediate-high risk group were with advanced age, high rate of diabetes mellitus, history of stroke, renal insufficiency, higher serum lactate and glucose at admission compared with low risk group. And more patients in intermediate-high risk group had impaired post-PCI coronary flow (TIMI flow grade<3). Conclusions The IABP SHOCK Ⅱ risk score is a simple and useful risk score for predicting in-hospital mortality of STEMIpatients complicated with CS. Though the patietns are treated with primary PCI and then supported by IABP, the in-hospital mortality of patients with IABP SHOCK Ⅱ risk score ≥ 3 increases significantly.

Severe anemia, malnutrition, hypotonia and aggravation of the conscious disturbance, methyl malonic acidemia or propionic acidemia? / 中华实用儿科临床杂志

The patient was a 21 days-old baby girl,admitted to Guangdong Women and Children Hospital because of "poor intake,seldom crying and no activity in 1 day".The major clinical manifestations included hypotonia,aggravation of the conscious disturbance,pancytopenia,intractable acidosis and hyperammonemia,so,inherited metabolic disorders should be considered.Screening of inherited metabolic diseases with blood and urine samples,genetic test and active treatments were carried out.After targeted next-generation sequencing,a novel homozygotic frame shift mutation in PCCB gene:c.838_839insC (L280Pfs * 11) was identified,which was validated by Sanger sequencing.This mutation had not been reported in the mutation database,and bioinformatic analysis of this mutation indicated disease-causing.So,the diagnosis of propionic acidemia was identified.The baby was in a critical condition,and despite active treatment,her conscious disturbance was aggravated,and the spontaneous breathing disappeared.Subsequently,the baby died of pneumonia.Propionic acidemia is a relatively common genetic metabolic disease in newborns.The severity and the clinical phenotypes of propionic acidemia varied,which often made the diagnosis difficult.When the baby is presented with developmental delay,hypotonia,recurrent convulsion and vomiting,etc,which can't be explained by common diseases of children,propionic acidemia may be considered.Next generation sequencing analysis of the complicated cases can easily to pinpoint a disease-causing gene,which lays a solid foundation for accurate diagnosis and treatment of the patients.

Influence of the growth traits and virulence genes of Enterococcus faecalis isolate N41 by cocultivation with Salmonella / 中国兽医学报

To explore the impact of Salmonella on Enterococcusfaecalis isolate N41 under the coexisting,the growth traits and the transcription of 26 virulence genes of N41 at various growth phases were detected.Salmonella and/or N41 were inoculated and done plate counting,then growth curves were drawn and bacterial total RNA were extracted at given time points,quantitive realtime PCR was used to analyze the RNA transcription levels of 26 virulence genes of N41.The result showed that comparison with single incubation,the bacteria concentration of N41 dropped about 3.9 times,and Salmonella dropped about 110-times.Among 26 virulence genes of N41,the RNA transcription levels of 12 virulence genes such as ebpA,ebpC,rnjB,ace,ebpR,psr and so on were promoted at the four growth phases,but the RNA transcription levels of SlyA and sprE were dropped.Except that the RNA transcription levels of CylL-S,CylL-L,efaA and AS had no significant changes at the four growth phases,the mostly rest genes increased dramatically at post-log phase.This indicated that when incubated together,N41 inhibited the growth of Salmonella significantly,and Salmonella promoted the transcription levels of virulence genes of N41 as a whole.The results lay a foundation for further research on the interaction between bacteria species and the pathogenicity mechanism of Enterococci.

Temporal lobe epilepsy and adult hippocampal neurogenesis / 浙江大学学报·医学版

Temporal lobe epilepsy (TLE) is a common and severe neurological disorder which is often intractable. It can not only damage the normal structure and function of hippocampus, but also affect the neurogenesis in dentate gyrus (DG). It is well documented from researches on the animal models of TLE that after a latent period of several days, prolonged seizure activity leads to a dramatic increase in mitotic activity in the hippocampal DG. However, cell proliferation returns to baseline levels within 3-4 weeks after status epilepticus (SE). Meanwhile, there are two major abnormalities of DG neurogenesis, including the formation of hilar basal dendrites and the ectopic migration of newborn granule cells into the polymorphic cell layer, which may affect epileptogenesis and seizure onset. However, the specific contribution of these abnormalities to seizures is still unknown. In other words, whether they are anti-epileptic or pro-epileptic is still under heated discussion. This article systematically reviews current knowledge on neurogenesis and epilepsy based on the results of studies in recent years and discusses the possible roles of neurogenesis in epileptogenesis and pathologic mechanisms, so as to provide information for the potential application of neurogenesis as a new clinical therapeutic target for temporal lobe epilepsy.

Correlation between vertebral artery dominance and posterior circulation ischemic stroke / 国际脑血管病杂志

Objective To investigate the correlation between vertebral artery dominance (VAD) and posterior circulation ischemic stroke (PCIS).Methods The consecutive patients with acute ischemic stroke hospitalized from November 2013 to October 2015 were collected.All patients underwent MRI and magnetic resonance angiography (MRA).The dominant vertebral artery was defined as having the larger diameter if left and right diameter difference ≥0.3 mm or the vertebral artery connected to the basilar artery in a more straight fashion if the diameter difference ＜ 0.3 mm.They were divided into either an anterior circulation ischemia stroke (ACIS) group or a PCIS group according to the classification criteria of Oxfordshire Community Stroke Project (OCSP).A multivariate logistic regression analysis was performed to investigate the correlation between VAD and PCIS.Results A total of 226 patients withacute ischemic stroke were enrolled,including 172 patients (76.1％) in the ACIS group and 54 (23.9％) in the PCIS group.Fifty-four patients (23.9％) had VAD,including 38 (70.3％) on the left and 16 (29.7％) on the right.The proportion of the patients with VAD in the PCIS group was significantly higher than that in the ACIS group (55.6％ vs.14.0％;x2 =39.115,P ＜ 0.001).Multivariate logistic regression analysis showed that VAD was an independent risk factor for patients occurring PCIS (odds ratio,13.60,95％ confidence interval 6.90-27.01;P＜0.001).Conclusions VAD is closely associated with the occurrence of PCIS,and it is an independent risk factor for PCIS.

Objective To investigate the relationship between plasma cell mastitis and prolactin. Methods The relationship between the lesion area , degree of inverted nipple and prolactin level of 228 plasma cell mastitis patients were observed , as well as their prolactin level before and after treatment , to explore the factors that influence relapse. Results There was no significant statistical relationship between prolactin level and lesions area and degree of inverted nipple. Prolactin level before and after treatment were statistically different (t =2.347,P = 0.02). Menstrual status, nipple status, comorbidities, lesion area and prolactin level were considered, only prolactin level was related with disease recurrence (P = 0.038). Conclusion prolactin level could significantly reduced as the disease cured , but elevated prolactin may lead to relapse of the disease.
