Objective: To develop a health literacy evaluation scale for Chinese high school students, providing a tool for dynamic monitoring of health literacy among high school students and evaluating the effectiveness of health school construction. Methods: Through theoretical research, an evaluation index system for health literacy of Chinese high school students was constructed. Two rounds of Delphi expert consultations were conducted to quantitatively screen the items, and the item pool was revised based on expert opinions to compile the health literacy evaluation scale for Chinese students. Two focus group interviews were held to collect suggestions from health educators, high school teachers, and high school students regarding optimized scale length, question types, difficulty and wording of the scale. The scale was revised accordingly. A pilot survey was conducted in Beijing and Tianjin in November 2024, and the reliability and validity of the scale were evaluated based on the pilot survey data. Results: The response rate in both rounds of Delphi expert consultations was over 80%, and the expert authority coefficient was over 0.70. The expert opinions were highly concentrated, and the dispersion was small. The revised item pool based on expert opinions contained 39 items. The revised scale based on the suggestions and opinions collected from the focus group interviews had a moderate number of questions and difficulty level. The pilot survey obtained 800 valid responses, with the response rate of 89.39%. The Cronbach α coefficient of the scale was 0.911, χ 2/df =3.321, the root mean square error of approximation was 0.054, the adjusted goodness-of-fit index was 0.991 , and the factor loadings of some items were less than 0.40. Conclusion The health literacy evaluation scale for Chinese high school students demonstrates scientific rigor and practical applicability, with good internal consistency and structural validity.

Objective: To develop and validate a health literacy assessment scale for junior high school students, providing an effective tool for evaluating and monitoring health literacy among Chinese adolescents. Methods: Based on school health education policy documents, a health literacy assessment framework was constructed, comprising five horizontal and four vertical dimensions. From May to June and August to September in 2024, the framework was refined through Delphi expert consultations and focus group discussions, leading to the development of the Health Literacy Assessment Scale for Junior High School Students. In September 2024, a convenience sample of 625 students from three junior high schools in Beijing and Tianjin completed the questionnaire. Item analysis, reliability, and validity tests were conducted to evaluate the scale. Results: The recovery rate for two rounds of expert consultation questionnaires was 100%. The expert authority coefficients ( Cr ) were 0.86 and 0.87 respectively (both >0.70), with Kendall W values of 0.34 and 0.27 ( P <0.05). The focus group discussions followed a rigorous structure, and after multiple rounds of item screening and revision, the version 3.0 of the junior high school students health literacy assessment scale was developed, comprising 57 items. Three items that failed to meet the comprehensive screening criteria were preliminarily removed, and the final scale contained 54 items. The scale demonstrated excellent reliability, with an overall Cronbach s α coefficient of 0.92 and split half reliability of 0.93. Confirmatory factor analysis [ χ 2/df =2.094, root mean square error of approximation ( RMSEA )=0.042, comparative fit index ( CFI )=0.911, Tucker Lewis index ( TLI )=0.907] indicated good model fit indices. Conclusions The preliminary development of the health literacy assessment scale for junior high school students follows a rigorous item screening process with well designed dimensions, demonstrating good reliability and validity, thus serving as an appropriate evaluation tool for adolescent health literacy.

Objective:To understand the gene carrying rate of neonatal genetic deafness in Dalian area, and to analyze the pedigree of 6 newborns with positive deafness gene test, to provide a reference basis for preventing genetic deafness.Methods:A total of 1 536 newborns born in Dalian Women′s and Children′s Medical Center (Group) from January to October in 2022 were retrospectively enrolled to detect the 4 genes of hereditary deafness, including GJB2, GJB3, SLC26A4 (PDS) and MT-RNRI (12SrRNA). Among them, 6 newborns with hereditary deafness were tested for NGS Panel gene.Results:A total of 85 deafness gene mutations were detected in 1 536 newborns, with the total carrying rate of 5.53% (85/1 536). Thirty-two cases of GJB2 mutations with carrying rate of 2.08% (32/1 536); 4 cases of GJB3 mutation of 0.26% (4/1 536); 32 cases of SLC26A4 (PDS) gene mutations of 2.08% (32/1 536); 14 cases of MT-RNRI (12SrRNA) mutations with carrying rate of 0.91% (14/1 536); 2 cases had compound heterozygous mutations of GJB2/GJB3, with a carrier rate of 0.13% (2/1 536); 1 cases had compound heterozygous mutations of GJB2/SLC26A4 (PDS), with a carrier rate of 0.07% (1/1 536); 1 case of compound heterozygous mutation in three-gene and a heterozygous mutation in KCNQ4 were detected in NGS Panel testing for hereditary deafness.Conclusions:Homozygous mutation and compound heterozygous mutation are the main factors of autosomal recessive gene deafness, and the NGS Panel gene detection is of great significance for gene traceability and the detection of rare deafness gene.

Objective:To analyze the results of the joint screening of newborn hearing and deafness genes in Dalian to provide a reference for the prevention and control of hereditary deafness.Methods:Eight hundred and forty-two neonates born in Dalian Women and Children′s Medical Group from January 1, 2022 to May 30, 2022 were screened retrospectively, using AABR (automatic brainstem evoked potential). And 20 mutation sites of common genetic deafness 4 genes , including GJB2, GJB3, SLC26A4 (PDS) and mitochondrial genes associated with drug-induced deafness (MT-RNRI)(12SrRNA), were detected by high-throughput sequencing.Results:Among the 842 newborns, 840 passed hearing screening (99.8%); 36 cases (4.3%) passed the hearing screening but not the hearing loss gene screening; 804 cases passed through the both screening (95.5%); 2 cases (0.24%) failed in the both screening. 38 cases of deafness gene mutations were detected, with a total carrying rate of 4.51% (38/842). Among them, the carrying rates of heterozygous mutations in GJB2, GJB3, SLC26A4 (PDS), MT-RNRI (12SrRNA) were 1.90%, 0.24%, 1.30%, and 0.95%, respectively. The carrying rates of GJB2/GJB3 composite heterozygous mutations were 0.12%.Conclusions:The combined screening of neonatal hearing and deafness genes can reduce the missed rate of hearing screening. The carrier rate of neonatal deafness gene in Dalian is 4.51%, with the highest GJB 2 carrier rate, followed by SLC26A4 (PDS) carrier rate.

Objective:To compare the efficacy and safety between WangShiBaoChiWan and mosapride in the treatment of functional dyspepsia (FD).Methods:From September 2019 to September 2020, patients with postprandial fullness and early satiation who met the Rome Ⅳ criteria for FD diagnosis were enrolled from 15 hospitals, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical College. The subjects were randomly divided into WangShiBaoChiWan (experimental) group and mosapride (control) group in the ratio of 1∶1. The treatment regimens were WangShiBaoChiWan+ mosapride simulator, WangShiBaoChiWan simulator+ mosapride, respectively with a treatment period of 2 weeks. The primary efficacy outcome was the improvement rates of main symptoms before and after treatment, the secondary efficacy primary efficacy outcome was the total clinical effective rate and the change of the single symptom score. And the safety indicator included adverse events. Independent sample t-test, paired t-test and chi-square test were used for statistical analysis. Results:A total of 251 FD patients were enrolled in the full analysis set, including 124 in the experimental group and 127 in the control group; 241 FD patients were in the per-protocol analysis set, including 117 in the experimental group and 124 in the control group. The analysis of per-protocol analysis set showed that the improvement rates of the main symptoms of the experimental group and the control group were (66±29)% and (60±30)%, respectively, and the difference was not statistically significant ( P>0.05). The improvement rate of the main symptoms of the experimental group reached 117% of that of the control group, which exceeded the expected non-inferiority standard of 80%. The total clinical effective rates of the experimental group and the control group were 76.07% (89/117) and 75.81% (94/124), respectively, and the difference was not statistically significant ( P>0.05). The results of full analysis set showed that the incidence of adverse events of the experimental group and the control group was 1.62% (2/124) and 1.57% (2/127), respectively, and the difference was not statistically significant ( P>0.05). There were no serious adverse events in the two groups. Conclusion:The improvement rate of the main symptoms of WangShiBaoChiWan is not inferior to that of mosapride in the treatment of FD, and it has good safety.

Background::The pharmacokinetic and clinical behaviors of many proton pump inhibitors (PPIs) in peptic ulcer treatment are altered by CYP2C19 genetic polymorphisms. This non-inferiority study evaluated the efficacy and safety of the novel PPI anaprazole compared with rabeprazole. We also explored the influence of Helicobacter pylori ( H. pylori) infection status and CYP2C19 polymorphism on anaprazole. Methods::In this multicenter, randomized, double-blind, double-dummy, positive-drug parallel-controlled, phase III study, Chinese patients with duodenal ulcers were randomized 1:1 to receive rabeprazole 10 mg + anaprazole placebo or rabeprazole placebo + anaprazole 20 mg once daily for 4 weeks. The primary efficacy endpoint was the 4-week ulcer healing rate assessed by blinded independent review. Secondary endpoints were the proportion of patients with improved overall and individual duodenal ulcer symptoms at 4 weeks. Furthermore, exploratory subgroup analysis of the primary endpoint by H. pylori status and CYP2C19 polymorphism was conducted. Adverse events were monitored for safety. Non-inferiority analysis was conducted for the primary endpoint. Results::The study enrolled 448 patients (anaprazole, n = 225; rabeprazole, n = 223). The 4-week healing rates were 90.9% and 93.7% for anaprazole and rabeprazole, respectively (difference, -2.8% [95% confidence interval, -7.7%, 2.2%]), demonstrating non-inferiority of anaprazole to rabeprazole. Overall duodenal ulcer symptoms improved in 90.9% and 92.5% of patients, respectively. Improvement rates of individual symptoms were similar between the groups. Healing rates did not significantly differ by H. pylori status or CYP2C19 genotype for either treatment group. The incidence of treatment-emergent adverse events was similar for anaprazole (72/220, 32.7%) and rabeprazole (84/219, 38.4%). Conclusions::The efficacy of anaprazole is non-inferior to that of rabeprazole in Chinese patients with duodenal ulcers.Registration::ClinicalTrials.gov, NCT04215653.

Objective:To explore the expression of miR-216a in patients with acute pancreatitis (AP) associated with acute lung injury (ALI) and its influence on endothelial cells permeability.Methods:40 AP patients admitted in Department of Gastroenterology of the First Affiliated Hospital of Navy Medical University from December 2015 to March 2016 were collected and were classified into AP with ALI (AP-ALI group, n=13) and AP without ALI (AP group, n=27) according to the presence or absence of ALI. 8 normal volunteers were enrolled in the control group. Blood samples were collected and the plasma samples were separated. Plasma RNA was extracted. miR-216a level in plasma was detected by RT-PCR. Plasma exosomes were extracted by exosome extraction kit and identified by the electron microscopy. Exosome RNA was extracted. miR-216a level in exosome was detected by RT-PCR. Plasma exosomes of AP-ALI patients were co-cultured with human umbilical vein endothelial cells (HUVEC, AP-ALI-HUVEC group) and anti-miR-216a transfected HUVECs (AP-ALI-anti-miR-216a HUVEC group) for 24 hours, respectively, and untreated HUVECs served as control group. Trans-endothelium electrical resistance (TEER) was measured by Millicell Ers-2 epithelial volt-ohmmeter to evaluate the cell permeability. Results:RT-PCR results showed that the expression level of plasma miR-216a in AP-ALI group (14.45±1.64) was significantly higher than that in AP group (11.08±1.6) and the control group (5.37±1.54) ( P<0.01). Under electron microscope, plasma exosomes were goblet like vacuoles, with the size of about 50-90 nm. The plasma exosomal miR-216a level in the AP-ALI group (14.03±1.58) was significantly higher than that in the AP group (10.86±1.31) and the control group (5.01±0.79), and the difference was statistically significant ( P<0.01). The resistance value of HUVEC in the control group was referred as 1, and the resistance ratio of HUVEC in AP-ALI-HUVEC group was 0.74±0.04, which was significantly lower than that of HUVEC in AP-ALI-anti-miR-216a HUVEC group (1.02±0.08), the difference was statistically significant ( P<0.01). Conclusions:miR-216a was highly expressed in plasma exosomes of AP patients with ALI. miR-216a can increase endothelial cell permeability, which may be associated with ALI during AP.

Objective To investigate the effect of CYP3A5 on the proliferation of pancreatic cancer cells and its underlying mechanisms.Methods The protein expression of CYP3A5 in five pancreatic cancer cell lines BxPC-3,FG,MDA28,8902 and PANC1 was detected by Western blotting.The PANC1 cells with the lowest protein expression of CYP3A5 and the BxPC-3 cells with highest expression of CYP3A5 were transfected with CYP3A5 overexpression plasmid and CYP3A5 targeted-siRNA (siRNA-CYP3A5),respectively.CCK-8 and cloning formation assay were used to investigate the role of CYP3A5 overexpression and knockdown in the proliferation of pancreatic cancer cells.The changes of the protein and mRNA expression of cell cycle regulating gene cyclin E,cyclin D1 and apoptosis related gene Bcl-2 were detected by Western blotting and PCR,respectively.Results CYP3A5 protein expression in PANC1 cells increased significantly after the transfection of CYP3A5 overexpression plasmid (1.66 ± 0.14 to 1,P =0.0021),which greatly decreased in BxPC-3 cells transfected with siRNA CYP3A5 (0.18 ± 0.02 to 1,P ＜0.0001).A450 values of the CYP3A5 overexpression group and the empty plasmid group in PANC1 cells cultured for 48 and 72 h were 1.36 ±0.05 vs 1.15 ± 0.03,2.1 ± 0.09 vs 1.42 ± 0.03,respectively,which were significantly higher in CYP3A5 overexpression group than empty plasmid group,and the differences were statistically significant (P value ＜ 0.005 or 0.001).The A450 values of BxPC-3 cells in CYP3A5-siRNA transfected group and siRNA-NC transfected group were 0.62 ±0.01 vs 0.77 ± 0.03、0.83 ± 0.01 vs 1.18 ± 0.02,respectively,which in The CYP3A5-siRNA transfection group was significantly lower than that of siRNA-NC transfection group,and the difference was statistically significant (P ＜ 0.05 or ＜ 0.001).The clone formation rate of PANC1 cells in the overexpression group was (19.33 ± 0.58)％,which was significantly higher than that in the empty plasmid group (9.67±0.63) ％,and the clone formation rate in CYP3A5-siRNA group was (8.5± 0.8)％,which was significantly lower than that of group siRNA-NC (16± 0.6)％,and the differences were statistically significant (P ＜0.01).The protein expression of cyclin D1 in CYP3A5 overexpression PANC1 cells was 2.00 ± 0.11,which was obviously higher than 1.00 in empty plasmid group (P ＜0.01).The protein expression of cyclin D1 in siRNA CYP3A5 BxPC cells was 0.45 ±0.04,which was obviously lower than 1.00 in siRNA NC group,and the difference was statistically significant (P＜0.01).However,CYP3A5 overexpression or inhibition did not influence the relative expression of cyclin D1 mRNA and cyclin E,Bcl-2 pretein expression.Conclusions CYP3A5 can promote the proliferation of pancreatic cancer cells by up-regulating cyclin D1 protein expression.
