Objective To analyze the prevalence status of cardiometabolic risk factor (CMRF) and its aggregation among workers engaged in new forms of employment. Methods A total of 5 429 new employment workers (including couriers, online food delivery workers, and ride hailing drivers) who underwent health medical examinations at a tertiary hospital in Beijing City were selected as the research subjects using the judgment sampling method. Data on waist circumference, blood pressure, blood glucose, and blood lipid levels were collected to analyze their CMRF [central obesity, elevated blood pressure, elevated blood glucose, elevated triglycerides, and reduced high-density lipoprotein cholesterol (HDL-C)] and their aggregation (with ≥ 2 of the above 5 risk factors) status. Results The detection rates of central obesity, elevated blood pressure, elevated blood glucose, elevated triglycerides, and reduced HDL-C were 61.2%, 38.2%, 29.5%, 40.9% and 22.6%, respectively. The detection rates of CMRF aggregation was 57.8%. The result of multivariable logistic regression analysis showed that male, age ≥45 years, smoking, overweight, and obesity were risk factors for CMRF aggregation (all P<0.05). Conclusion The detection rate of CMRF and its aggregation among workers with new forms of employment in Beijing City is relatively high. Targeted prevention and control efforts should be strengthened for high-risk populations, especially males, workers aged ≥45 years, smokers, and those who are overweight or obese.

Objective To investigate the predictive value of the expression levels of YY1 transcription fac-tor(YY1)and microRNA(miR)-181a-5p in peripheral blood mononuclear cell for adverse pregnancy out-comes in gestational diabetes mellitus(GDM).Methods A total of 200 patients with GDM were enrolled as the GDM group.100 healthy pregnant women who underwent prenatal examinations during the same period were selected as the control group.The expressions levels of YY1 and miR-181a-5p in peripheral blood mono-nuclear cell were detected by fluorescent quantitative PCR.Receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of YY1 and miR-181a-5p for adverse pregnancy outcomes in GDM pa-tients.Results Compared with the control group,the expression levels of YY1 and miR-181a-5p in peripheral blood mononuclear cell of GDM group were obviously decreased(P＜0.05),and the incidence rates of post-partum hemorrhage,macrosomia and neonatal hypoglycemia in GDM group were obviously higher(P＜0.05).Multivariate Logistic regression analysis showed that age and poor blood glucose control were inde-pendent risk factors for adverse pregnancy outcomes in GDM patients(P＜0.05),and the expression levels of peripheral blood mononuclear cell YY1 and miR-181a-5p were independent protective factors for adverse preg-nancy outcomes in GDM patients(P＜0.05).ROC curve results showed that the area under the curve(AUC)of the expression levels of YY1 and miR-181a-5p in peripheral blood alone and in combination in predicting ad-verse pregnancy outcomes in GDM patients was 0.717,0.751 and 0.832,respectively,and the AUC of their combination was obviously higher than that of the two alone(P＜0.05).Conclusion The decreased expres-sion levels of YY1 and miR-181a-5p in peripheral blood mononuclear cell of GDM patients could increase the risk of adverse pregnancy outcomes,YY1 and miR-181a-5p are closely related to adverse pregnancy outcomes in GDM patients,and both could be used as predictors of adverse pregnancy outcomes in GDM patients.

Objective To explore the safety and feasibility of intravenous dexmedetomidine(Dex)combined with targeted infusion of remifentanil in endoscopic retrograde cholangiopancreatography(ERCP)anesthesia in older adult patients.Methods From January to August 2021,98 older adult patients(≥65 years old)undergoing ERCP were randomly divided into TRP and TRD groups.The TRP group was anesthetized with target-controlled infusion of propofol and remifentanil and the TRD group was treated with Dex combined with target-controlled infusion of remifentanil.mean arterial pressure(MAP),heart rate(HR),electrocardiogram(ECG),respiratory rate(RR),pulse oxygen saturation(SpO2),bispectral index(BIS)before anesthesia induction(T0),immediately after induction of anesthesia(T1),endoscopic introduction(T2),duodenal papilla intubation(T3),endoscopy withdrawal(T4)and postoperative awakening(T5)were observed.Arterial blood gas analysis at different time points(T0,every 15 min after anesthesia induction and T5),PaO2,and PaCO2,were recorded at the above mentioned time points;and the remifentanil concentration in target-controlled infusion,operation time,recovery time(from infusion of remifentanil to consciousness recovery),anesthesia recovery time(from consciousness recovery to leaving the operating room),intraoperative body movement,Aldrete scores out of the room,Visual Analogue Scale(VAS)at 60 min after surgery,occurrence of post-operative adverse reactions,as well as the satisfaction of anesthesiologists,endoscopists,and patients were recorded.Results Compared with the TRP group,MAP at T1 and T3,SpO2 and RR at T1,T2,T3,and T4,and BIS at T2,T3,T4,and T5 increased,whereas HR at T1,T2,T3,and T4 decreased;the number of mandibular rests,incidence of hypoxemia,Aldrete score,and satisfaction increased,whereas the VAS score at 60 min after surgery decreased in the TRD group(P<0.05).There were no statistically significant differences in postoperative adverse reactions,PaO2 and PaCO2,target-controlled infusion remifentanil concentration,operation time,recovery time,and anesthesia recovery time between the two groups.Conclusion Compared with the target-controlled infusion of propofol-remifentanil,intravenous infusion of Dex combined with target-controlled infusion of remifentanil can reduce the incidence of hypoxemia in older adult patients during ERCP surgery,and the anesthesia regimen can meet the anesthesia needs of ERCP surgery,which is safe and feasible.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

Objective To investigate the clinical significance of serum S100 calcium binding protein(S100 A4)and S100A12 in patients with severe traumatic brain injury(sTBI).Methods A total of 147 sTBI pa-tients admitted to Handan Central Hospital from March 2021 to March 2023 were selected as the sTBI group,and 50 healthy subjects who underwent physical examination in Handan Central Hospital during the same pe-riod were selected as the control group.The correlation between S100A4,S100A12 levels and brain injury markers and the influencing factors of early death in sTBI patients were analyzed,and the predictive value of serum S100A4 and S100A12 for early death in sTBI patients was studied.Results The serum levels of S100A4,S100A12,myelin basic protein(MBP),S100B and neuron specific enolase(NSE)in sTBI group were significantly higher than those in control group(P＜0.05).The serum levels of S100A4 and S100A12 were positively correlated with MBP,NSE and S100B in sTBI patients(P＜0.05).Multivariate Logistic regression analysis showed that decreased Glasgow coma scale(GCS)score on admission and increased serum levels of S100A4,S100A12,MBP,NSE and S100B were risk factors for early death in sTBI patients(P＜0.05).Receiv-er operating characteristic curve showed that the combination of serum S100A4 and S100A12 with GCS score,MBP,NSE and S100B was superior to any single detection in predicting early death in sTBI patients.Conclu-sion The serum levels of S100A4 and S100A12 are increased in sTBI patients,which are related to the aggra-vations of brain injury and early death.The combined detection of S100A4 and S100A12 has a good predictive value for early death in sTBI patients.

Premature ovarian insufficiency(POI),also known as"ovarian insufficiency",has an incidence of 1％～5％.The incidence has been on the rise in recent years,seriously affecting women's physical and mental health and quality of life.At present,the cause and mechanisms of POI are still unclear,and the method and applications of model construction are also confusing.Most models have some shortcomings in pertinence and stability.The limitations greatly limit research into the clinical diagnosis and treatment of POI.This paper summarizes and discusses the etiology and pathogenesis of POI and the construction of POI animal models to provide a comprehensive reference for those studying POI.

OBJECTIVE To investigate the improvement mechanism of caudatin on liver injury of rats. METHODS SD rats were randomly divided into blank group， model group， caudatin low-dose and high-dose groups （25， 50 mg/kg）， with 6 rats in each group. Diethylnitrosamine （DEN） was injected intraperitoneally three times per week for eight weeks to establish liver injury model of rats. At 5th week of modeling， the rats received relevant medicine or 0.5% sodium carboxymethylcellulose intragastrically for 4 weeks. The levels of liver function indexes [alanine transaminase （ALT）， aspartate transaminase （AST）， total protein （TP） and total bilirubin （TBI）] and inflammatory factors [interleukin （IL-6）， tumor necrosis factor α （TNF-α）， IL-1β] in serum were detected； the histopathological morphological changes of rat liver were observed； the positive protein expressions of nuclear factor κB （NF-κB） and 78 kDa glucose regulatory protein （Grp78） in liver tissue were also determined； the expressions of endoplasmic reticulum stress-related protein Grp78， C/EBP homologous protein （CHOP）， activating transcription factor 6 （ATF6） and inositol requiring enzyme 1α （IRE1α） and the level of protein kinase R-like endoplasmic reticulum kinase robertluoyi@126.com （PERK） in liver tissue were detected. RESULTS Compared with blank group， serum levels of ALT， AST， TBI， IL-6， TNF-α and IL-1β and positive expressions of NF-κB and Grp78 in liver tissue as well as protein expressions of Grp78， CHOP， ATF6 and IRE1α， PERK protein phosphorylation level were all increased significantly in model group （P＜0.05）， while the serum level of TP was decreased significantly （P＜0.05）. The disordered structure of liver lobule， swollen liver cells， unclear intercellular boundary were observed and accompanied by inflammatory cell infiltration. Compared with model group， most of the above indexes were significantly reversed in caudatin groups （P＜0.05）； the structure of hepatic lobule was relatively complete and clear， the cells were arranged orderly， and the infiltration of inflammatory cells was also reduced. CONCLUSIONS Caudatin has a significant improvement effect against DEN-induced liver injury in rats， the mechanism of which may be associated with inhibiting endoplasmic reticulum stress and inflammatory reaction.

Platinum-based chemotherapy resistance is a key factor of poor prognosis and recurrence in hepatocellular carcinoma (HCC). Herein, RNAseq analysis revealed that elevated tubulin folding cofactor E (TBCE) expression is associated with platinum-based chemotherapy resistance. High expression of TBCE contributes to worse prognoses and earlier recurrence among liver cancer patients. Mechanistically, TBCE silencing significantly affects cytoskeleton rearrangement, which in turn increases cisplatin-induced cycle arrest and apoptosis. To develop these findings into potential therapeutic drugs, endosomal pH-responsive nanoparticles (NPs) were developed to simultaneously encapsulate TBCE siRNA and cisplatin (DDP) to reverse this phenomena. NPs (siTBCE + DDP) concurrently silenced TBCE expression, increased cell sensitivity to platinum treatment, and subsequently resulted in superior anti-tumor effects both in vitro and in vivo in orthotopic and patient-derived xenograft (PDX) models. Taken together, NP-mediated delivery and the co-treatment of siTBCE + DDP proved to be effective in reversing chemotherapy resistance of DDP in multiple tumor models.

Objective:To investigate the clinical characteristics of patients with combined oxidative phosphorylation deficiency type 4 (COXPD4) related to TUFM gene variation, in order to improve clinicians′ understanding of the disease. Methods:A case of COXPD4 with cystic leukodystrophy admitted to the Children′s Hospital of Zhengzhou University in June 2021 was taken as the study subject, and her clinical characteristics and genetic testing results were retrospectively analyzed. The "combined oxidative phosphorylation deficiency type 4" " TUFM gene" "cystic leukodystrophy" "combined oxidative phosphorylation deficiency 4" "COXPD 4" " TUFM" and "cystic leukodystrophy" were used as keywords, and the documents on COXPD4 related to TUFM gene mutations were reviewed from Wanfang Data Knowledge Service Platform, CNKI, PubMed Document Database, and National Center for Biotechnology Information (NCBI) until August 2021. The COXPD4 patients that have been reported internationally were analyzed for clinical features and variant types. Results:The patient was a 2-month-old girl with clinical manifestations of delayed development and progressive aggravation, elevated lactic acid in serum and cerebrospinal fluid, and diffuse white matter dysplasia with multiple cystic lesions in cerebral magnetic resonance imaging (MRI). Whole exome sequencing showed TUFM gene complex heterozygous variants c.684_684+4delGGTGA and c.1105C>T, which had not been reported in the past. A total of 5 cases of COXPD4 were reported in 4 English literatures. Together with 1 case in this study, there were 4 cases with detailed clinical history data, including 1 male and 3 females. The clinical manifestations were severe early-onset lactic acidosis and developmental lag, and 3 cases were accompanied by progressive infantile encephalopathy. Among them, 3 cases underwent head MRI examination, all of which showed diffuse white matter signal with multiple cystic lesions, 2 cases with basal ganglia involvement and multiple cerebellar gyri deformity. Genetic test indicated different types of TUFM gene variation. Conclusions:COXPD4 is a rare hereditary mitochondrial disease. For cases with COXPD4 clinical and imaging features, TUFM gene mutations can be screened first.

Objective:To investigate the clinical phenotype and genotypic characteristics of Legius syndrome.Methods:The clinical data of a child with precocious puberty and scattered café-au-lait macules admitted to Department of Neurology of the Children′s Hospital Affiliated to Zhengzhou University in July 2021 were retrospectively analyzed. Trio-whole exome sequencing (trio-WES) was used for genetic analysis to confirm the molecular diagnosis of the family. The relevant literature was reviewed to summarize the clinical characteristics of the disease.Results:The proband was a 10-year and 9-month-old girl, presenting with more than 5 café-au-lait macules with diameter>5 mm on the face and trunk, freckles in the axillary, without Lisch tubercles of iris and tumor signs of neurofibromatosis type 1, diagnosed as central precocious puberty at the age of 8. trio-WES results of the family revealed a spontaneous heterozygous nonsense mutation c.751(exon7) C>T in SPRED1 gene, causing a nonsense mutation in the amino acid sequence p.Arg251Ter (p. Ter251 *). Literature review showed a total of 88 pathogenic mutations were reported in SPRED1 gene, including frameshift mutations (41/88), nonsense mutations (31/88), splice mutations (7/88), missense mutations (6/88), and others (3/88), and no mutational hotspots were found. Clinical phenotype was as follows:>5 café-au-lait macules accounted for 92.8% (168/181), armpit and inguinal freckles 43.5% (73/168), macrocephaly 21.4% (31/145), learning disability 18.0% (30/166), psychomotor retardation 13.8% (22/159), lipoma (adult) 13.7% (21/153), Noonan facial sign 12.1% (21/173), and tumor phenotype of neurofibromatosis type 1 was not reported. Conclusions:The central precocious puberty phenotype of Legius syndrome was not reported in China. The clinical phenotype of Legius syndrome was mild, with a large variation, but without neurofibromatosis type 1 tumor phenotype. Genetic testing can be beneficial for early diagnosis of Legius syndrome.
