Objective: To understand the knowledge, attitude, and current status of vaccination of herpes zoster vaccination among urban residents aged 25 years and above in China. Methods: In August to October 2022, a convenience sampling method was used to survey residents aged 25 years and above at 36 community centers in 9 cities across China. Questionnaires were used to collect basic information, knowledge, and attitude toward herpes zoster and its vaccination, as well as vaccination status and reasons for non-vaccination among residents. Results: A total of 2 864 urban residents were included in the study. The total score of residents' cognition of herpes zoster and its vaccine was 3.01±2.08, and the total score of their attitude was 18.25±2.76. Factors such as being male (β=-0.45, P<0.001), older than 40-59 years (β=-0.34, P=0.023) or ≥60 years (β=-0.68, P<0.001), married (β=-0.69, P=0.002) were negatively associated with knowledge score. The educational level of high school or secondary school (β=0.44, P=0.036), college (β=0.65, P=0.006), bachelor's degree and above (β=1.20, P<0.001), annual net household income ≥120 000 Yuan in 2021 (β=0.42, P=0.020), having urban employee medical insurance (β=0.62, P=0.030), having public or commercial medical insurance (β=0.65, P=0.033), and having a history of chickenpox (β=0.29, P=0.025) were positively associated with knowledge scores. Being male (β=-0.38, P=0.008) and not remembering a history of chickenpox (β=-0.49, P=0.012) were negatively associated with attitude scores. Annual net household income in 2021 was between 40 000-80 000 Yuan (β=0.44, P=0.032) or between 80 000-120 000 Yuan (β=0.62, P=0.002) or ≥120 000 Yuan (β=0.93, P<0.001), and a history of herpes zoster (β=0.59, P=0.004) were positively associated with attitude scores. Of the 2 864 residents surveyed, only 29 (1.01%) had received the herpes zoster vaccine, with a vaccination rate of 1.70% for those aged 50 years and above, with the main reason for non-vaccination being lack of knowledge about the herpes zoster vaccine, followed by the high price. 42.67% of the population said they would consider getting the herpes zoster vaccine in the future. Conclusion: Low knowledge of herpes zoster and its vaccine, positive attitudes towards the preventive effects of herpes zoster and its vaccine, and extremely low vaccination rates among the urban population in China call for multiple measures to strengthen health education and vaccination recommendations for residents, especially for the elderly, low-education and low-income populations.

Objective:To assess the altered right atrial(RA) function using two-dimensional speckle-tracking imaging(2D-STI) in patients with persistent pulmonary hypertension of the newborn(PPHN), and investigate the diagnostic value of different right heart strain parameters in PPHN.Methods:Ultrasound images of 42 newborns with clinically confirmed diagnosis of PPHN in the neonatal intensive care unit of Shenzhen Children′s Hospital (median gestational age 37 + 1 weeks, median age 6 d) and 30 normal newborns (control group, median gestational age 37 + 3 weeks, median age 6.5 d) from January 2020 to January 2023 were retrospectively analyzed, all with gestational age ≥34 gestational weeks. 2D-STI was applied to evaluate RA function: RA strain(RA LS) and area change fraction(RA FAC), where RA LS included RA reservoir strain (εs), RA conduit strain (εe) and RA active contract strain (εa), while evaluating right ventricle(RV) function: RV global longitudinal strain(RV GLS), RV FAC, etc. And the degree of pulmonary artery pressure(PAP) was assessed by tricuspid regurgitation velocity(TRV). The above parameters were compared between the PPHN group and the control group, and the correlations between RA function parameters, RV function parameters and PAP in PPHN group were analyzed. The area under ROC curve (AUC) was used to compare the accuracy of each parameter in the evaluation of impaired cardiac function in PPHN patients. Results:Compared with the control group, RA function (εs, εe, εa and RA FAC) were impaired in PPHN patients (all P<0.05). εs was positively correlated with RV GLS, RA FAC ( r=0.494, 0.356, both P<0.05) and negatively correlated with minimum right atrial area (RAA min), pulmonary artery diameter (PAD), and tricuspid annular internal diameter ( rs=-0.285, r=-0.495, -0.396; both P<0.05); εe was negatively correlated with PAD ( rs=-0.256, P<0.05); εa was positively correlated with RV GLS ( r=0.499, P<0.05) and negatively correlated with PAD and tricuspid annular internal diameter ( r=-0.390, -0.380; both P<0.05); RA FAC was positively correlated with RV GLS ( r=0.365, P<0.05) and negatively correlated with PAD and tricuspid annular internal diameter ( r=-0.439, -0.328; both P<0.05). RA LS and RA FAC had no correlations with TRV-estimated PAP ( P>0.05). ROC analysis showed that the sensitivity and specificity of εs<40.50% for diagnosing PPHN was 0.905 and 0.800, respectively, with an AUC of 0.929; the sensitivity and specificity of RV GLS<18.55% for diagnosing PPHN were 0.905 and 0.900, respectively, with an AUC of 0.963; εs combined with RV GLS was the best indicator for early detection of right heart functional impairment in PPHN, with sensitivity and specificity of 0.905 and 1.000, respectively, and AUC was 0.985. Conclusions:RA function and RV function are both impaired in PPHN patients. εs combined with RV GLS is the best indicator for early assessment of right heart function impairment and diagnosis of PPHN.

OBJECTIVE: To study the hematologic and molecular features of 14 patients with hemoglobin (Hb) variants, so as to provide reference data for its laboratory screening. METHODS: A total of 1 029 samples were screened by high performance liquid chromatography (HPLC) on the Bio-Rad VariantⅡHPLC system. GAP-PCR and reverse dot blot (RDB) were used to detect common mutation of α and β globin gene in Chinese. DNA sequencing for α and β globin gene was simultaneously performed in samples with abnormal spectrum peak and negative thalassemia gene. RESULTS: In 1 029 samples, 10 types of structural Hb variants were detected in14 cases (1.36%), including 1 case of Hb E / β- thalassemia, 1 case of Hb E /α- thalassemia (HbH disease), 2 cases of HbG-Taipei, 2 cases of Hb Q-Thailand, 2 cases of Hb Youngstown, 1 case of Hb Guangzhou-Hangzhou, 1 case of Hb M-Boston, 1 case of Hb G-Siriraj, 1 case of Hb J-Baltimore, 1 case of Hb J-Sicilia and 1 case of Hb Tamano. CONCLUSION The occurrence of abnormal structural Hb variants with many genotypes in Shanghai is unique. Except for Hb E, Hb Youngstown, and Hb M-Boston, other types of heterozygous are normal in phenotypes, and symptoms such as hemolysis and anemia often occur when other diseases are combined.

All 50/1 830(2.7%) patients underwent surgery after unsuccessful enema reduction, including 42 cases of primary intussusception, and 8 cases of secondary intussusception. The complication of intestinal perforation occurred in 3 cases (0.16%), and there were no deaths.Conclusions:Ultrasound-guided enema reduction for pediatric acute intussusception is an effective and safe method without radiation exposure, and can be used as the preferred method for non-operative treatment of intussusception.

Resistance of tumor cells is a complex biological process involving multiple mechanisms and factors, in which anti-apoptosis is the most important cause of drug resistance. Previous studies have shown that the DNA binding activity of Runt related transcription factor 3 (RUNX3) increased prominently in Herceptin resistant gastric cancer cells (NCI N87R) while the relevance of which to drug resistance has not yet been confirmed. In this study, we employed CRISPR/Cas9 to establish RUNX3 knock-out cell line (△RUNX3/NCI N87R) to investigate the functions of RUNX3 in Herceptin resistance of NCI N87R cells and its potential mechanisms. We investigated proteomics profiling of △RUNX3/NCI N87R cells based on label free quantitative proteomics. Differentially expressed proteins were screened out according to fold change and significance level between △RUNX3/NCI N87R and NCI N87R cells. Pathway enrichment analysis was done using GeneAnalytics database, and gene ontology analysis was conducted by DAVID Bioinformatics Resources database. Protein-protein interaction networks were constructed based on STRING database. The results showed that △RUNX3/NCI N87R cells increased the sensitivity to Herceptin. Proteomic data demonstrated that the expression of 577 genes changed significantly in △RUNX3/NCI N87R cells, among which 191 genes were up-regulated while 386 ones down-regulated comparing with NCI N87R cells. Pathway analysis showed that autophagy, cell cycle, apoptosis, mitochondrial fatty acid β oxidation, neurogenic locus notch homolog protein 1 (NOTCH1), mammalian target of rapamycin (mTOR), Hedgehog and DNA damage response pathways exhibited notable changes based on pathway enrichment ratio and significance level (P < 0.05). These results indicated that RUNX3 knock-out altered multiple signaling pathways of NCI N87R cells. Western blotting manifested that the expression of autophagy regulatory molecules autophagy-related protein (ATG) 13, 7 and BECN1 increased remarkably while cell cycle molecules serine/threonine-protein kinase Chk2 (CHEK2) and apoptosis regulator Bcl-2 (BCL2) decreased prominently in △RUNX3/NCI N87R cells. The p-AKT expression decreased significantly in △RUNX3/NCI N87R cells compared with NCI N87R cells (P < 0.01) and was suppressed by Herceptin. These results indicated that RUNX3 knock-out altered cell cycle, increased inhibition to p-AKT by Herceptin, promoted autophagy and induced cell apoptosis of NCI N87R cells. These results suggested that RUNX3 may be a potential therapeutic target for reversing or reducing Herceptin resistance in gastric cancer cells.

Objective:To explore the pathogenic variants of a family with syndromic deafness by high-throughput sequencing.Methods:The family was from Puyang City, Henan Province, and had four members, including two with syndromic deafness. The proband and his sister had congenital deafness, and their parents had normal phenotypes. The clinical phenotype of the family was characterized using clinical examinations and pedigree analysis. The clinical examinations included imaging examination, audiometry (pure tone audiometry, acoustic immittance, brainstem auditory evoked potential, and otoacoustic emission), vestibular function test, and ophthalmic examination (visual acuity test, visual field test, fundus examination, visual evoked potential, and electroretinogram). Target exome sequencing of 129 known deafness genes and bioinformatics analysis were used to screen suspected pathogenic variants. Sanger sequencing and minigene assay were used to verify and functionally investigate the mutation detected, respectively. According to the standards and guidelines for interpreting genetic variants proposed by the American College of Medical Genetics and Genomics, the variants c.6049G>A and c.8699A>G were classified as pathogenic/likely pathogenic, and the variant c.9856C>G was classified as variants of uncertain significance.Results:The probands and his sister had severe sensorineural hearing loss with decreased binocular vision, night blindness, decreased peripheral visual field sensitivity and partial visual field defect, and normal vestibular function. Both of them had three CDH23 mutations, including CDH23 (NM_022124.5) c.6049G>A (p.Gly2017Ser),c.9856C>G (p.His3286Asp), and c.8699A>G (p. Asp2900Gly), The first two were inherited from the father, and the last one was from the mother. The missense variants c.9856C>G and c.8699A>G were not included in the gnomad database. The missense mutation c.6049G>A was located in the last position of exon 46 and was predicted to affect splicing by bioinformatics software. The minigene experiment showed that the mutation cause exon skipping of exon 46, resulting in an abnormal protein. Conclusions:Compound heterozygous variations of the CDH23 are the leading cause of USH1D in the family. This study confirms that the compound heterozygosity of splicing and missense variants of the CDH23 gene could lead to USH1D.

Objective:To develop and evaluate the effect of Professional Care APP for stroke patients at home. Methods:Professional Care APP 1.0 was developed by reviewing literature, analyzing APP function and consulting expert, and combined with the findings at the early stage. And then it was upgraded to APP 2.0 after a 4-week trial in 10 stroke patients at home, which included two parts: patient-side and medical-side. The patient-side provided health education, rehabilitation guidance, medication reminder, online consultation and so on. From December, 2017 to June, 2018, 77 stroke patients in a community in Zhengzhou, China were conveniently selected and randomly divided into control group (n = 39) and intervention group (n = 38). The control group received routine community follow-up, and the intervention group received Professional Care APP 2.0, for 12 weeks. Results:After a 12-week intervention, the level of knowledge and medication compliance was significantly higher in the intervention group than in the control group (t > 4.205, P < 0.001). The score of demand for professional care was significantly lower in the intervention group than in the control group (t = -18.183, P < 0.001). The intervention group made a good evaluation for APP in usefulness, ease of learning, usability, credibility, acceptability and satisfaction. Conclusion:Professional Care APP can meet the professional care needs, and improve the level of knowledge on disease and medication compliance for stroke patients at home. The patients' evaluation for APP is ideal.

The aim of this paper was to investigate the effects of curcumin on the proliferation,migration,invasion and apoptosis of human gastric cancer cells and to explore the potential mechanisms. SGC7901,MKN45 and NCI N87 cells lines were cultured under different concentrations of curcumin( 2. 5,5,10,20,40,80 and 160 μmol·L~(-1)) at different time points( 12,24,48 and 72 h),and the effect of curcumin on cell proliferation was detected by CCK-8 assay. The migration and invasiveness of cells were determined by wound healing and Transwell assays,the apoptosis rate was assessed by flow cytometry,the expression of N-cadherin,E-cadherin,snail1,Wnt3 a,p-β-catenin,p-LRP6,Bcl-2 and Bax were detected by Western blot,and the enzymatic activity of caspase-3,caspase-8 and caspase-9 was evaluated via caspase kit. RESULTS:: indicated that the proliferation of MKN45 cells was significantly inhibited by curcumin in a dose-and time-dependent manner( IC50= 21. 93 μmol·L~(-1)). Moreover,curcumin could inhibit the migration and invasion of MKN45 cells,downregulate the expression of N-cadherin,snail1,Wnt3 a,p-β-catenin,p-LRP6 and Bcl-2,and upregulate the expression of E-cadherin and Bax,it could increase the activity of caspase-3,caspase-8,caspase-9 and induce apoptosis as well. The potential mechanism is through inhibiting the Wnt3 a/β-catenin/EMT pathway,regulating Bcl-2 signaling and caspase pathway,which might provide new potential strategies for gastric cancer treatment.

BACKGROUNDSH3TC2, PMP2, and BSCL2 genes are related to autosomal recessive (AR) Charcot-Marie-Tooth (CMT) disease type 1, autosomal dominant (AD)-CMT1, and AD-CMT2, respectively. Pathogenic variants in these three genes were not well documented in Chinese CMT patients. Therefore, this study aims to detect SH3TC2, PMP2, and BSCL2 pathogenic variants in a cohort of 315 unrelated Chinese CMT families.

METHODSA total of 315 probands from 315 unrelated Chinese CMT families were recruited from the Department of Neurology of Third Xiangya Hospital and Xiangya Hospital. We screened for SH3TC2 pathogenic variants in 84 AR or sporadic CMT probands, PMP2 pathogenic variants in 39 AD or sporadic CMT1 probands, and BSCL2 pathogenic variants in 50 AD or sporadic CMT2 probands, using polymerase chain reaction and Sanger sequencing. All these patients were out of 315 unrelated Chinese CMT families and genetically undiagnosed after exclusion of pathogenic variants of PMP22, MFN2, MPZ, GJB1, GDAP1, HSPB1, HSPB8, EGR2, NEFL, and RAB7. Candidate variants were analyzed based on the standards and guidelines of American College of Medical Genetics and Genomics (ACMG). Clinical features were reevaluated.

RESULTSWe identified three novel heterozygous variants such as p.L95V (c.283C>G), p.L1048P (c.3143T>C), and p.V1105M (c.3313G>A) of SH3TC2 gene and no pathogenic variants of PMP2 and BSCL2 genes. Although evaluation in silico and screening in the healthy control revealed that the three SH3TC2 variants were likely pathogenic, no second allele variants were discovered. According to the standards and guidelines of ACMG, the heterozygous SH3TC2 variants such as p.L95V, p.L1048P, and p.V1105M were considered to be of uncertain significance.

CONCLUSIONSSH3TC2, PMP2, and BSCL2 pathogenic variants might be rare in Chinese CMT patients. Further studies to confirm our findings are needed.
