Objective: To understand the epidemiological and spatial clustering characteristics of hand-foot-mouth disease in Pingxiang City, Jiangxi Province from 2013 to 2023, so as to provide the evidence for improving hand-foot-mouth disease prevention and control measures. Methods: Data of hand-foot-mouth disease cases in Pingxiang City from 2013 to 2023 were collected from the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Demographic, temporal, and regional distribution characteristics were described. The trend in incidence was analyzed using the average annual percent change (AAPC). The spatial clustering and aggregation patterns of hand-foot-mouth disease were identified using global and local spatial autocorrelation analyses. Results: A total of 58 020 hand-foot-mouth disease cases were reported in Pingxiang City from 2013 to 2023, with an average annual incidence of 289.71/105. No significant trend in the reported incidence of hand-foot-mouth disease was observed (AAPC=-7.398%, P>0.05). Among them, 33 892 were males and 24 128 were females, with infants aged 0-<3 years accounting for 70.59% of the total (40 958 cases). The peak incidence occurred mainly from May to June and from September to December. Luxi County had the highest average annual reported incidence of 677.10/105. Spatial autocorrelation analysis indicated significant spatial clustering of hand-foot-mouth disease in 2018, 2019, 2021, and 2022 (Moran's I=0.314, 0.339, 0.381, and 0.668, all P<0.05). High-high clustering areas were primarily identified in 7 townships (streets) of Anyuan District, 2 in Xiangdong District, 4 in Shangli County, and 1 in Luxi County. Conclusions The reported incidence of hand-foot-mouth disease in Pingxiang City from 2013 to 2023 remained stable overall, with higher susceptibility among young children and peak incidence during summer and autumn. Spatial clustering of hand-foot-mouth disease was observed, expanding northward and southwestward from Anyuan District as the core area.

Objective To investigate the relationship between combined plasma ferritin and triglyceride (TG) concentrations in early pregnancy and the risk of gestational diabetes mellitus (GDM). Methods A total of 1 000 pregnant women who had antenatal care at the Sixth Hospital of Wuhan from January 2021 to January 2023 were selected as the research subjects. The cut-offs of ferritin and TG were analyzed by using unrestricted cube splines. All participants were divided into 4 groups according to the cut‐off values of ferritin and TG. Associations between combined ferritin and TG concentrations and GDM risk were estimated using multivariable logistic regression models. Results A total of 158 (15.8%) participants were diagnosed with GDM. The ferritin and TG levels in early pregnancy of pregnant women in the GDM group were significantly higher than those in the non-GDM group (P<0.05). After adjusting for potential confounders, the OR for the risk of developing GDM after combining ferritin with TG was 2.35 (1.65, 3.35). Couclusion The increase in plasma ferritin and TG concentrations in early pregnancy is positively correlated with the increased risk of GDM. Pregnant women with high plasma ferritin (˃65.7 ng/mL) and high TG (˃1.9mmoL/L) have the greatest risk of GDM.

Objective:To investigate the effect of mobile phone dependence on suppression control under the conditions of emotional loss and cognitive loss in college students.Methods:A total of 553 college students were recruited,and 108 in the mobile phone dependence group and 194 in the non-dependent group were screened with the Mobile Phone Addiction Tendency Scale(MPATS).Ninety-nine of them were selected to participate in experi-ment 1,and the effect of emotional loss on the inhibitory control,and 101 students were selected to participate in ex-periment 2 to investigate the effect of cognitive loss on the inhibitory control.The GO/NOGO paradigm was used to compare the correct rate and response of different mobile phones dependent on college students under different emo-tional and cognitive depletion conditions.Results:In experiment 1,the main effect of emotional loss was statistically significant[F(1,55)=6.16,178.91;Ps＜0.05],the inhibition control accuracy rates were lower and reaction tim-es were shorter in the high emotional loss group than in the low emotional loss group.In experiment 2,the main effect of the group was statistically significant[F(1,57)=17.90,19.06;Ps＜0.001],the accuracy rates of inhibi-tion control were lower and the inhibition control reaction times were longer in the mobile phone-dependent group than in the non-dependent group.The interaction between groups and cognitive loss types was statistically significant[F(1,57)=7.95,P＜0.01],and the inhibition control accuracy rates of the mobile phone-dependent group were lower under high cognitive loss.Conclusion:Emotional loss and cognitive loss could reduce the inhibition and con-trol ability of individuals,and the mobile phone dependence group is more likely to be affected in the case of cogni-tive loss.

OBJECTIVE To analyze the influential factors on trough concentration （cmin） and area under the drug concentration time curve （AUC） of voriconazole （VRZ） in pediatric patients with thalassemia undergoing hematopoietic stem cell transplantation （HSCT）. METHODS A total of 60 pediatric patients with thalassemia undergoing HSCT who used VRZ for prevention or treatment of invasive fungal infection were collected in our hospital from January 2021 to January 2024. The plasma concentration of VRZ was measured by high-performance liquid chromatography and the AUC was calculated. The factors affecting cmin and AUC of VRZ were analyzed using multiple linear regression. RESULTS A total of 120 cases of VRZ cmin in 60 pediatric patients was obtained and 27 cases of VRZ AUC in 26 pediatric patients were obtained. The median concentration of VRZ cmin was 0.31 mg/L； 46 cases had a cmin in 0.5-5 mg/L（ 38.33%）， 2 cases had a cmin＞5 mg/L（ 1.67%）， and 72 cases had a cmin＜0.5 mg/L. The median AUC of VRZ was 11.68 mg·h/L. The patient’s body weight， HSCT postoperative days， lymphocyte count， and combined use of phenytoin sodium， tacrolimus or cyclosporine had significant effects on VRZ cmin （P＜0.05）. Lymphocyte count and combined use of phenytoin sodium had significant effects on VRZ AUC （P＜0.05）. CONCLUSIONS The body weight， HSCT postoperative days， lymphocyte count， and combined use of phenytoin sodium， tacrolimus or cyclosporine are independent factors affecting VRZ cmin. Lymphocyte count and combined use of phenytoin sodium are independent factors affecting VRZ AUC.

ObjectiveTo investigate the pathogenic spectrum and molecular characteristics of infectious diarrhea among children in Putuo District of Shanghai from 2018 to 2023， and to provide scientific basis for the prevention and control of infectious diarrhea in children. MethodsFecal samples from the cases visited sentinel hospitals for children’s diarrheal disease in Putuo District， Shanghai， were collected from January 2018 to December 2023. A total of 11 species of bacteria were isolated and cultured， and 5 species of viruses were detected by real-time fluorescent polymerase chain reaction （PCR）. The molecular typing of some positive strains was analyzed by the standard pulsed-field gel electrophoresis （PFGE） method. The polymerase-capsid protein linkage region of some norovirus-positive samples was amplified by reverse transcription PCR， and was sequenced and analyzed by bioinformatics software. The Chi-square test and Fisher’s exact probability test were used to compare the pathogen-positive rates in 2018‒2019 and 2020‒2023. ResultsOf the 707 cases of children with infectious diarrhea， the total positive rate was 47.67%， with a single bacterial positivity rate of 16.27%， a single viral positivity rate of 22.63%， and a mixed positivity rate of 8.77%， respectively. The dominant pathogens were rotavirus （10.75%）， norovirus （10.33%）， enteropathogenic Escherichia coli （8.06%）， Salmonella （6.36%）， enteroaggregative Escherichia coli （5.52%）， and Campylobacter （5.23%）. Bacterial infections were predominant in summer and fall， and viral infections were predominant in winter and spring. The total positive rate decreased in 2020‒2023 compared with that of 2018‒2019 （χ²=5.753，P<0.05）. Thirty-seven strains of Salmonella， 81 strains of diarrheagenic Escherichia coli， and 19 strains of Campylobacter were completed for the molecular typing analysis by PFGE， which were classified into 28， 80 and 18 banding types， respectively， with a wide range of banding similarity. Nineteen copies of norovirus GⅡ group gene sequences were analyzed and classified into 5 genotypes， which were mainly GⅡ.Pe-GⅡ.4 and GⅡ.P16-GⅡ.2 types. ConclusionRotavirus， norovirus， diarrheagenic Escherichia coli， Salmonella， and Campylobacter are the dominant pathogens of infectious diarrhea in children in Putuo District of Shanghai. The pathogen spectrum shows a trend of seasonal epidemic characteristics， with a diversity of molecular characteristics of some pathogens. Surveillance and monitoring on molecular characteristics of the pathogens of infectious diarrhea in children should be strengthened in different seasons， so as to provide a laboratory basis for the prevention and control of infectious diarrhea.

Objective To investigate the expression,synergistic relationship and clinical significance of alcohol de-hydrogenase(ADH1A)and vascular endothelial growth factor-A(VEGFA)in hepatocellular carcinoma(HCC).Methods The expression and correlation of ADH1A and VEGFA in HCC and adjacent normal tissues were ana-lyzed by GEPIA.TCGA and GSEA were used to analyze the pathway of ADH1A in HCC.The clinical and patho-logical data of 84 patients with HCC were collected,and 54 patients with paracancer normal tissue samples were se-lected as controls to analyze the correlation between ADH1A and VEGFA and clinicopathological parameters of HCC.Immunohistochemistry was used to detect the protein expression of ADH1A and VEGFA in cases and con-trols,and the correlation between the expression of ADH1A and VEGFA and the clinical progression and prognosis of patients with HCC was analyzed based on clinical pathological parameters and Kaplan-Meier.Results Bioinfor-matics analysis found that ADH1A was low-expressed in HCC and VEGFA was highly expressed in HCC,and there was a negative correlation between the two(P<0.001);immunohistochemical detection results showed that the expression of ADH1A in HCC tissue was lower than that in normal tissue adjacent to cancer(P<0.01)while the expression rate of VEGFA in HCC tissue was significantly higher than that of normal tissue adjacent to cancer(P<0.01);The recurrence rate of vascular thrombus and HCC patients in HCC group with high expression of ADH1A was lower(P<0.05).The proportion of tumor diameter>5 cm,high TNM stage,microsatellite and G2-G3 dif-ferentiation in HCC tissues in VEGFA high expression group was higher(P<0.05).Kaplan-Meier survival analy-sis showed that patients with high ADH1A expression and low VEGFA expression had a higher five-year survival rate.Conclusion Low expression of ADH1A and high expression of VEGFA in tumor tissues of patients with HCC indicate tumor progression and can be used as one of the prognostic evaluation indicators for patients with HCC.

Objective:To evaluate the impact of preemptive analgesia with ibuprofen on postoperative pain following the extraction of impacted mandibular third molars in a Chinese population, aiming to provide a clinical reference for its application.Methods:This multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted from April 2022 to October 2023 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), and Beijing Chao-Yang Hospital, Capital Medical University (20 cases). It included 82 patients with impacted mandibular third molars, with 41 in the ibuprofen group and 41 in the control group. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups were instructed to take sustained-release ibuprofen capsules as planned for 3 days post-surgery. Pain intensity was measured using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h after surgery, and the use of additional analgesic medication was recorded during days 4 to 6 postoperatively.Results:All 82 patients completed the study according to the protocol. No adverse events such as nausea, vomiting, or allergies were reported in either group during the trial. The ibuprofen group exhibited significantly lower pain scores at 4 h [2.0 (1.0, 4.0) vs. 4.0 (3.0, 5.0)] ( Z=-3.73, P<0.001), 6 h [2.0 (1.0, 4.0) vs. 5.0(2.5, 6.0)] ( Z=-3.38, P<0.001), and 8 h [2.0 (1.0, 4.0) vs. 5.0 (2.0, 6.0)] ( Z=-2.11, P=0.035) postoperatively compared to the control group. There were no statistically significant differences in pain scores between the groups at 30 min, 24 h, 48 h, and 72 h postoperatively ( P>0.05). Additionally, 11 out of 41 patients (26.8%) in the ibuprofen group and 23 out of 41 patients (56.1%) in the control group required extra analgesic medication between days 4 and 6 post-surgery, with the ibuprofen group taking significantly fewer additional pills [0.0 (0.0, 1.0) vs. 1.0 (0.0, 3.0)] ( Z=-2.81, P=0.005). Conclusions:A pain management regimen involving 300 mg of oral sustained-release ibuprofen capsules administered 15 minutes before surgery and continued for 3 d postoperatively effectively reduces pain levels and the total amount of analgesic medication used after the extraction of impacted mandibular third molars. Considering its efficacy, safety, and cost-effectiveness, ibuprofen is recommended as a first-line drug for perioperative pain management, enhancing patient comfort during diagnosis and treatment in a feasible manner.

Objective:To evaluate the effect of preemptive analgesia with ibuprofen on postoperative pain following single posterior tooth implantation, aiming to provide a clinical reference for its application.Methods:A multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted. A total of 82 participants were included in the trial, meeting the eligibility criteria from April 2022 to April 2024 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), Beijing Chao-Yang Hospital, Capital Medical University (20 cases). Participants were randomly assigned in a 1∶1 ratio to either the ibuprofen group or the control group, with each group comprising 41 individuals. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups received the same postoperative analgesic regimen for 3 days. Pain scores were assessed using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h postoperatively, and the additional use of analgesic medication was recorded from days 4 to 6 postoperatively.Results:A total of 82 participants were initially enrolled in the study, with 7 dropouts (4 from the control group and 3 from the ibuprofen group), resulting in 75 participants (37 in the control group and 38 in the ibuprofen group) completing the trial. There were no reports of adverse events such as nausea or vomiting among the participants. The ibuprofen group exhibited significantly lower pain scores at 4 h, 6 h and 8 h [1.0 (0.0, 2.0), 1.0 (0.0, 2.0), 1.5 (0.0, 3.0) ] postoperatively compared to the control group 4 h, 6 h and 8 h [2.0 (1.0, 3.0), 3.0 (1.5, 4.0), 2.0 (1.0, 4.0)] ( Z=-1.99, P=0.047; Z=-3.01, P=0.003; Z=-2.10, P=0.036). The proportions of patients requiring additional analgesic medication between days 4 and 6 post-surgery were 18.4% (7/38) in the ibuprofen group and 27.0% (10/37) in the control group, with no significant difference (χ 2=0.79, P=0.373). The median additional medication usage postoperatively was [0.0 (0.0, 0.0) pills] in the ibuprofen group and [0.0 (0.0, 1.0) pills] in the control group, with no significant difference ( Z=-0.78, P=0.439). Conclusions:Preemptive analgesia with ibuprofen effectively reduces postoperative pain following tooth implantation, representing a safe and effective perioperative pain management strategy.

Objective·To study the alterations in vestibular hair cell morphology and function of ATPase plasma membrane Ca2+transporting 2 oblivion(Atp2b2 Oblivion)heterozygous mice at different ages.Methods·Atp2b2 Oblivion heterozygous male mice aged 2 months and 8 months were selected with ten in each kind and C57BL/6J wild-type mice with the same gender,age and number were selected as the control group.Expression patterns of ATP2B2 in vestibular hair cells and numbers of hair cells in the striola zone and the extra striola zone in the two groups of mice at different ages were observed and calculated respectively through immunofluorescence assay.Hair bundle structures were detected by scanning electron microscopy(SEM),and mitochondria and ribbon synapse structures were observed by transmission electron microscopy(TEM).Vestibular evoked potential(VsEP),vestibular evoked myogenic potential(VEMP),rotarod rod test,and balance beam test were adopted for the evaluation of vestibular functions.Results·ATP2B2 was mainly expressed in the hair bundle of vestibular hair cells in the two groups of mice.Hair cell numbers in the striola zone and the extra-striola zone did not exhibit any differences between Atp2b2 Oblivion heterozygous mutant mice and wild-type mice of 2-month-old and 8-month-old.No visible structural abnormality in the hair bundle could be seen through SEM.TEM results implied no morphological abnormality in mitochondria or ribbon synapses in the 2-month-old heterozygous mutant mice,while vacuolar degeneration was discovered in the mitochondria under the cuticular plate in the 8-month-old heterozygous mutant mice with the normal ribbon synapses and the normal mitochondria near the innervation site.VsEP and VEMP thresholds of 2-month-old and 8-month-old Atp2b2 Oblivion heterozygous mutant mice were significantly elevated compared with the wild-type mice.Analysis of VsEP waveform manifested prolonged P1 latency and declined P1N1 amplitude in heterozygous mutant mice(P＜0.05).Results of rotarod rod test and balance beam test acquired from 2-month-old Atp2b2 Oblivion heterozygous mutant mice were not significantly different from the wild-type mice,while the ability of the mutant mice to accomplish the tests descended significantly at 8 months of age compared with the wild-type mice(P＜0.05).Conclusion·Atp2b2 Oblivion heterozygous mutant mice showed defective vestibular electrophysiological function at 2 months old,and abnormalities in vestibule-related behaviors can be detected at 8 months old.The vestibular function ofAtp2b2 Oblivion heterozygous mutant mice deteriorate progressively.
