Objective To examine the characteristics of the prevalence of congenital cleft lip with/without cleft palate in the ethnic Tibetan population and to provide support for the precise prevention and treatment of cleft lip with/without cleft palate in the Tibetan population.Methods The clinical data of Tibetan patients with cleft lip with/without cleft palate were collected and the clinical characteristics of the patients were analyzed.The patients'age ranged from 2 months to 51 years old.All the subjects were admitted to West China Stomatology Hospital,Sichuan University for the treatment of cleft lip with/without cleft palate between January 2016 and August 2023.Most of the subjects came from Sichuan Province and the Tibet Autonomous Region.Results A total of 1 051 patients were enrolled and children aged under 12 months(460 cases)accounted for the largest proportion.Among the subjects,383 had cleft lip only(36.44%),140 had cleft palate only(13.32%),and 528 had cleft lip with cleft palate(50.24%).The male-to-female ratios of patients with cleft lip only(0.99∶1),cleft palate only(0.54∶1),and cleft lip with cleft palate(1.67∶1)exhibited significant differences(P＜0.001).However,there was no significant difference in the male-to-female ratio in patients with cleft lip only or those with cleft lip with cleft palate when the subjects were divided into two groups according to whether they had unilateral or bilateral cleft lip with/without cleft palate.Most of the patients with bilateral cleft lip were female,while most of the patients with unilateral cleft lip and unilateral or bilateral cleft lip with cleft palate were male.The unilateral cleft lip with/without cleft palate was located predominantly on the left side.Syndromic cleft lip with/without cleft palate accounted for 3.43%of all the cases and the most common concomitant deformity was congenital heart disease.3.81%(40 cases)of the patients had a family history.In the patients with cleft lip only and those with cleft palate only,the proportion of patients having parents with corresponding phenotypes was higher than those of other phenotypes of cleft lip with/without cleft palate.Regarding the birth time distribution of the children with cleft lip with/without cleft palate,Spring saw the highest number of births of these children(311 cases,29.59%),while Winter saw the lowest number of births(231 cases,21.98%).Conclusion The cases of cleft lip with/without cleft palate in the ethnic Tibetan population are predominantly cleft lip and palate.Unilateral cleft lip only or cleft lip with palate is predominantly located on the left side.Lip disease phenotypes may be more heritable.

Objective Congenital cleft lip and palate is a common birth defect that seriously affects the lives of the afflicted children and their families.Previously,no research has been done to investigate the pathogenic characteristics of cleft lip and palate among ethnic minorities,for example,Tibetans,a minority ethnic group with a large population in China.This study aims to investigate the relationship between the occurrence of cleft lip and palate in Tibetans and Han Chinese in western China and the distribution of ABO blood groups and Rh blood groups to provide a theoretical basis for the precise prevention and treatment of cleft lip and palate.Methods In this study,statistics on Tibetan patients with cleft lip and palate,some Han patients with cleft lip and palate,and normal controls from western China were retrospectively collected.All participants were patients from West China Stomatology Hospital,Sichuan University.All patients with cleft lip and palate received treatment at the hospital between January 2016 and September 2023.The normal controls were outpatients or inpatients who did not have cleft lip and palate,and who received treatment at the hospital between January 2020 and October 2023.Information on the A,B,O,and AB blood groups and Rh positive and negative blood groups of the patients was collected and compared with that of the normal controls.The incidence of different phenotypes,including cleft lip alone,cleft palate alone,and cleft lip with cleft palate,in patients of blood groups A,B,O and AB were statistically analyzed by Chi-square test.Results A total of 1227 Tibetan patients with cleft lip and palate,4064 Han patients with cleft lip and palate,and 5360 normal controls were included in the study.Among all the patients with cleft lip and palate,1863 had cleft lip alone,1425 had cleft palate alone,and 2003 had cleft lip with cleft palate.The ABO blood group distribution of Tibetan patients with cleft lip and palate was characterized as O＞B＞A＞AB,with Rh positive blood group accounting for 100%,blood type O accounting for 41.15%,and blood type B accounting for 30.64%.The blood group distribution of the Han patients with cleft lip and palate was characterized as O＞A＞B＞AB,with Rh positive blood group accounting for 99.58%,blood type O accounting for 35.78%,and type A accounting for 30.54%.There was a significant difference in ABO blood groups between Tibetan and Han patients with cleft lip and palate(P＜0.005),but no significant difference in Rh blood groups.The ABO blood group distribution of the Tibetan patients with cleft lip and palate showed an obvious difference from that of the control group,while those of the Han patients with cleft lip and cleft palate and the control group did not show obvious differences.In the analysis of the subtypes,it was found that the blood group distribution in the subtypes of cleft lip alone,cleft palate alone,and cleft lip with cleft palate in the Tibetan population was O＞B＞A＞AB,while that in the Han Chinese population was O＞A＞B＞AB.There were differences in blood group distribution between Tibetans and Hans of the subtypes of cleft lip alone and cleft lip with cleft palate(P＜0.001),but there was no difference in blood group distribution in the population of cleft palate-only subtype.The proportion of blood type O in Tibetan patients with cleft lip and palate was significantly higher than that in the Han patients with cleft lip and palate.The blood group distribution of Tibetan patients with cleft lip and palate in Sichuan Province,Xizang Autonomous Region,and Qinghai Province was always O＞B＞A＞AB.Tibetan patients from Shiqu County and Baiyu County,Ganzi Tibetan Autonomous Prefecture and Chaya County,Qamdo City were predominantly of blood type B,and those from other regions were mainly of blood type O.Conclusion There were significant differences in the phenotype composition and ABO blood group distribution between the Tibetan and Han populations with cleft lip and palate in western China.The distribution of blood group O in the population with cleft lip and palate was higher than that in the normal population,and the same trend was observed for different phenotypes.However,differences between Tibetan and Han populations in ABO blood group distribution were only found in the phenotypes of cleft lip only and cleft lip with palate.Tibetans with blood type O are more prone to cleft lip deformity than Han people,and the effect in the phenotype of cleft lip with palate is less pronounced than that in the phenotype of cleft lip only.

Objective:To develop and examine the reliability and validity of the adolescent health literacy evaluation scale under public health emergencies (AHLES-PHE) in junior middle school students.Methods:The initial version of AHLES-PHE was formed by combining the characteristics of public health emergencies and adolescent health literacy.The expert version of AHLES-PHE was formed by two rounds of Delphi expert consultation.Totally 1 729 adolescent students from three junior middle schools in Changzhou City were tested.The formal version of AHLES-PHE was formed through item analysis and factor analysis (structural validity). The content validity of the formal version of AHLES-PHE was evaluated by specialist analysis and sensibility analysis, and its correlation validity with the everyday health information literacy (EHIL) was tested.The internal consistency reliability, parity split-half coefficient and test-retest reliability were calculated.Results:(1)Item analysis: the correlation coefficient between the scores of each item and the total score of AHLES-PHE expert version was 0.420 to 0.722 ( P<0.01), and the CR of decision value was 10.140 to 66.980 ( P<0.01). (2)Validity analysis: the formal version of AHLES-PHE with 45 items and 8 factors was obtained by exploratory factor analysis.The 8 factors could explain 61.30% of the total variation.The fitting indexes of the confirmatory factor analysis model were χ2/ df=3.325, RMSEA=0.052, GFI=0.853, CFI=0.912, TLI=0.904, NFI=0.880.Sensibility analysis of the formal version of AHLES-PHE showed the Cronbach's α ranged from 0.957 to 0.958.The correlation coefficient between the total score of AHLES-PHE formal version and the total score of EHIL was 0.340 ( P<0.01). (3)Reliability analysis: the Cronbach's α coefficient and parity split-half coefficient of the formal version of AHLES-PHE were 0.958 and 0.975, respectively.The test-retest reliability of the formal version of AHLES-PHE was 0.753 ( P<0.01). Conclusion:The formal version of AHLES-PHE developed in this study has good reliability, structural validity and content validity, and the correlation validity with EHIL is common.This scale has a certain degree of applicability to the assessment of health literacy for junior middle school students under public health emergencies.

Abstract Health literacy is closely related to the response to public health emergencies. This paper begins with health literacy evaluation tools in adults, then focuses on recent progress made in health literacy evaluation tools in adolescents from the perspective of public health emergencies. The development of adolescent health literacy evaluation tools, health education and health literacy from the perspective of public health emergencies should be greatly enhanced, helping adolescents to better respond to public health emergencies and maintain their physical and mental health.

Tea green leafhopper(TGL),Empoasca onukii,is of biological and economic interest.Despite numerous studies,the mechanisms underlying its adaptation and evolution remain enig-matic.Here,we use previously untapped genome and population genetics approaches to examine how the pest adapted to different environmental variables and thus has expanded geographically.We complete a chromosome-level assembly and annotation of the E.onukii genome,showing nota-ble expansions of gene families associated with adaptation to chemoreception and detoxification.Genomic signals indicating balancing selection highlight metabolic pathways involved in adaptation to a wide range of tea varieties grown across ecologically diverse regions.Patterns of genetic vari-ations among 54 E.onukii samples unveil the population structure and evolutionary history across different tea-growing regions in China.Our results demonstrate that the genomic changes in key pathways,including those linked to metabolism,circadian rhythms,and immune system functions,may underlie the successful spread and adaptation of E.onukii.This work highlights the genetic and molecular basis underlying the evolutionary success of a species with broad economic impacts,and provides insights into insect adaptation to host plants,which will ultimately facilitate more sustain-able pest management.

Objective: To investigate the effects of Shenqi Yizhi Granules on PI3K/AKT signaling pathway in Aβ1-42 bilateral hippocampal injection of AD model rats. Methods: A rat model of AD was established by bilateral hippocampus injection of Aβ1-42. Shenqi Yizhi granules were used for 60 days. Morris water maze was used to detect the learning and memory function of each rat. HE staining was used to observe the pathological changes of rat hippocampal CA3 area. Immunohistochemistry was used to detect the expression of PI3K and AKT protein in hippocampus. The relative expression levels of PI3K mRNA and AKT mRNA were detected by RT-PCR. Results: Compared with the blank group, the escape latency of the model group was significantly prolonged, and the number of entering the platform, the time and percentage of crossing the platform quadrant decreased significantly (P ＜ 0.05). At the same time, the vertebral cells in the hippocampal CA3 area were disordered and the neurons showed obvious lesions. PI3K/AKT showed significant inhibition at both protein and gene levels (P ＜ 0.05). After intervention with Shenqi Yizhi Granule, the escape latency of the model rats was significantly shortened, and the number of entering the platform and the time of crossing the platform quadrant were significantly increased (P ＜ 0.05). Conclusion: Shenqi Yizhi Granules can improve the cognitive function of Aβ1-42 bilateral hippocampus injection in AD rats, and its mechanism may be related to activation of PI3K/AKT signaling pathway in brain.

AIM To observe the effects of Qibao Meiran Oral Liquid (Polygoni multiflori Radix Praeparata,Angelicae sinensis Radix,Psoraleae Fructus,etc.) on learning and memory function,hippocampus tissue pathological morphology,SOD activity and carbonyl protein content in SAMP8 mice.METHODS Twenty-seven SAMP8 mice were randomly and equally divided into model control group,donepezil hydrochloride group and Qibao Meiran Oral Liquid group.Another nine SAMR1 mice were selected as normal control group.Mice were given successive intragastric administration for 60 days.On the 56th day,the passive avoidance test was adopted,and the learning and memory capacities were determined after 5 d;The pathological morphology was observed by HE staining;ELISA assay was used to detect the activity of SOD and the content of carbonyl protein in brain tissue.RESULTS Compared with the model control group,the escape latency of mice in the Qibao Meiran Oral Liquid group was significantly prolonged,and the number of errors decreased significantly (P ＜0.01);the pathological morphology of hippocampus tissue was significantly improved;SOD activity increased significantly,and carbonyl protein content decreased significantly (P ＜ 0.01).CONCLUSION Qibao Meiran Oral Liquid can not only improve the learning and memory function of SAMP8 mice,but also reduce the degree of hippocampus tissue degenerative disease.

Objective To evaluate the clinical outcomes and report the second-look arthroscopic findings of reconstructed anterior cruciate ligament (ACL) using deep-frozen allograft.Methods Sixty-six patients undergoing ACL reconstruction using deep-frozen allograft in our institute with at least twelve months follow-up from January 2012 to March 2016 were included and received second-look arthroscopy.The patients consisted of 51 males and 15 females with an average age of 30.6 years (range,18 to 55 years) at the time of ACL reconstruction.Knee functions were evaluated by Lysholm score and International Knee Documentation Committee (IKDC) score.Knee stability was evaluated by drawer test,Lachman test and KT-1000 arthrometer.Second-look arthroscopic evaluation was performed in all patients,focused on continuity of the reconstructed ACL,the synovial coverage and subjective tension of the graft,and the prevalence of cyclops-like lesion and other changes after reconstruction procedures.Resuits All patients were followed up for average 18.3 months (range,12 to 36 months).Thirty-one patients underwent second-look arthroscopy from 12 to 18 months,and the other 35 patients underwent second-look arthroscopy from 18 to 36 months after ACL reconstruction.No infection,rejection reaction and other serious complication were reported after operation.The knee range of motion was normal in all cases,except that 10° extension limitation in one case.The Lysholm score significantly improved from preoperative 54.95±9.01 to 12 months postoperatively 86.14±5.86,and the IKDC improved from 54.79±9.12 to 85.11±5.77.Lachman test was positive in 8 cases,but negative in 58 cases postoperatively.KT-1000 arthrometer measurement showed that the side-toside difference significantly improved from preoperative 6.70± 1.24 mm to postoperative 1.52± 1.02 mm.Complete discontinuity occurred in 2 cases of the reconstructed grafts,graft tear in 4 cases.Cyclops-like mass was identified in 2 cases.The overall synovial coverage was slightly better in the patients who were followed up more than 18 months than those less than 18 months.However,there was no significant difference among the groups in the field of graft tension.The patients with taut grafts showed statistically better KT-1000 values (1.14±0.35 mm) than those with lax grafts (2.95±1.38 mm).Conclusion Frozen allograft could be a reasonable choice for ACL reconstruction.However,the graft integration and remodeling could tend to be slow.

Objective To study the physiological indicators and arterial blood gas values,and create a reliable data for researchers using beagle dogs.Methods Beagle were sampled before and after Zoletil anesthesia (10 mg/kg) via intramuscular injection.Then aterial blood gas was detected by blood gas analyzer.Then the physiological indicators,including heart rate,blood pressure and body temperature were measured via large animal ECG.Results For blood gas values,the pH value decreased significantly (P ＜ 0.01).pCO2 increased significantly and pO2 decreased significantly,the differences were significantly (P ＜ 0.05).In contrast,levels of Lac and HCO3-remained unaltered,indicating a typical respiratory acidosis.For physiological indicators,blood pressure increased slightly,but not significant.The heart rate increased significantly (P ＜ 0.01) and body temperature decreased significantly (P ＜ 0.01).There was no difference between sexes.Conclusion Zoletil anesthesia causes respiratory arrest and respiratory congestion,which further induced respiratory acidosis.Meanwhile,anesthesia also results in elevated heart rhythm and lower body temperature.These data indicate that warming and airway clear are necessary during anesthesia in Beagles.Moreover,it should be considered about the effects of anaesthetics when comparing differents in animals before and after treatment.

Objective: To evaluate the efficacy and safety of oseltamivir in the treatment of suspected influenza in children. Method: A multicenter, randomized and open-label trial was conducted among 229 individuals with suspected influenza which were collected from the clinic of 5 hospitals in Guangdong province (Guangzhou Women and Children′s Medical Center, Shenzhen Baoan District Maternity and Child Care Service Center, the Second Affiliated Hospital of Shantou University Medical College, Dongguan Maternity and Child Care Service Centre, Yuexiu District Children′s Hospital of Guangzhou) from April to July 2015. They were randomized either to oseltamivir group (oseltamivir 30-75 mg, twice daily for 5 days) or control group who were given symptom relief medicines for 5 days. Result: No significant difference was found between two groups in influenza symptoms of the patients before the treatment(P>0.05). Altogether 229 individuals (114 in oseltamivir group, 115 in control group) were analyzed for efficacy, in which 73 individuals (42 oseltamivir, 31 control), 31.9%, were identified as influenza-infected through laboratory test. No significant difference was found between the two groups in the duration of fever although shortened. In the 229 individuals , the cumulative alleviation proportion between oseltamivir and control group was not significantly different (P>0.05): the median duration of illness was 69.9 hours (95% CI 65.3-91.5) in oseltamivir group and 75.4 hours (95%CI 63.9-91. 7) in control group; the median duration of fever was 40.4 hours (95%CI 31.5-53.4) in oseltamivir group and 44.0 hours (95%CI 33.2-50.0) in control group. In the 73 individuals, the cumulative alleviation proportion between oseltamivir and control group was significantly different (P<0.05). The median duration of illness was 61.2 hours (95%CI 48.0-121. 0) in oseltamivir group, being significantly shorter than that of 116.0 hours (95%CI 91.5-175.0) in control group. But it was not significantly different that the median duration of fever was 32.8 hours (95%CI 24.0-47.0 ) in oseltamivir group and 55.8 hours (95%CI 43.6-78.3 ) in control group (P>0.05). And the median duration of fever in 60 individuals (38 oseltamivir, 22 control) was significantly different between two groups(P<0.05), who had finished a course of taking oseltamivir in the 73 individuals, 34.8 hours (95%CI 24.0-48.5 ) in oseltamivir group being significantly shorter than that of 53.3 hours (95%CI 43.6-104.0 ) in control group. There was certain difference in side effects rate between the two groups (oseltamivir 10%, control 2%, P<0.05). The main side-effects were gastrointestinal symptoms (stomachache, diarrhea, poor appetite, vomiting). Conclusion The duration of illness and fever in suspected influenza patients treated with oseltamivir was shorter than those in the patients treated with no oseltamivir, the difference was not statistically significant, when 31.9% was confirmed with positive result of virus test in suspected influenza in children. But in these patients with positive result of virus test, the duration of illness was significantly shortened with treatment with oseltamivir as compared with no treatment with oseltamivir, and it would be better if full oseltamivir course was completed for reducing the duration of fever. Oseltamivir treatment was safe with mild side effects.
