[Objective] To resolve the ambiguities of HLA genotyping generated by next generation sequencing (NGS) using nanopore sequencing technology. [Methods] A total of 38 samples with ambiguous HLA genotyping by NGS in our laboratory were collected, and HLA-A, -B, -C, -DRB1, -DRB3/4/5, -DQA1, -DQB1, -DPA1 and -DPB1 loci in these samples were amplified using primers in the same commercial NGS HLA genotyping kit, then subjected to third-generation library construction, and sequenced on the nanopore sequencer. The sequencing data were converted into Fastq files and analyzed by software, and the genotypes of 11 HLA loci were obtained. The ambiguities were counted directly. [Results] The high-resolution genotyping at the second domain of 11 HLA loci of 38 samples using the third generation sequencing (TGS) were consistent with the results of the NGS method at a rate of 100%. The genotypes for the HLA-A, -B, -C, -DRB3, -DRB4, -DQA1 and -DPA1 loci by TGS were all only one result, and the discrimination rate for ambiguities of the HLA-A, -B, -C, and -DQA1 loci (all caused by the difficulty in phasing due to the short NGS read length) was 100%. Among the HLA-DRB1, -DRB5, -DQB1 and -DPB1 loci, the discrimination rate of TGS for the ambiguities caused by non-amplification of exon 1 was 0% and by the short NGS read length was 100%. [Conclusion] Nanopore technology was used to identify the ambiguities of 11 HLA loci in this study, and the ambiguities caused by the short read length disadvantage of the NGS method could be solved effectively and the accuracy of HLA genotyping would be improved.

OBJECTIVE To evaluate the cost-utility of ciclesonide （CIC） versus budesonide （BUD） for the maintenance treatment of mild to moderate bronchial asthma. METHODS From the perspective of Chinese health service system， a Markov model was established based on the data from a clinical trial in China and some literature. The cycle length was 1 week， the time horizon was 60 years. A discount rate of 5% per year was applied. Cost-utility analysis was performed on therapeutic scheme of CIC and BUD using three times of China’s per capita gross domestic product （GDP） in 2023 as the threshold of willing-to-pay （WTP）. One-way sensitivity analysis， probabilistic sensitivity analysis and scenario analysis were applied to test the uncertainty of basic analysis. RESULTS Compared with BUD scheme， the incremental cost of the CIC scheme was 9 401.67 yuan， and the incremental quality-adjusted life years（QALYs） were 0.001 3； incremental cost-effectiveness ratio （ICER） was 6 928 868.26 yuan/QALY， far beyond the threshold of WTP 268 074 yuan/QALY. One-way sensitivity analysis showed that the usage， dosage and unit price of CIC and BUD were parameters that had a significant impact on ICER； probabilistic sensitivity analysis showed that the basic analysis results were relatively robust； scenario analysis showed that， when the price of CIC reduced to 159.95 yuan/branch， the probability of CIC scheme having economics was similar to that of BUD scheme. CONCLUSIONS At the current price， CIC is not economical compared with BUD for the maintenance treatment of mild to moderate asthma， using three times of China’s GDP in 2023 as the threshold of WTP.

Objective: To explore the impact of sleep quality, experience of childhood maltreatment, and their interaction on depressive symptoms among middle school students, so as to provide the reference for early intervention of depressive symptoms among middle school students. Methods: From September to December 2023, a questionnaire survey was conducted among 1 231 students from two secondary schools in Harbin, Heilongjiang Province by a convenient sampling method. The survey included general demographic information, Childhood Trauma Questionnaire Short Form, Pittsburgh Sleep Quality Index and Short Version of Center for Epidemiological Studies Depression Scale. The Chi square test was used to analyze the differences in depressive symptom, sleep quality and childhood maltreatment among students with different demographic characteristics. Correlation analysis was conducted using Logistic regression, and interaction analysis was performed by both additive and multiplicative interaction models. Results: The detection rate of depressive symptoms among middle school students was 22.7%, and the rate for high school students (35.2%) was significantly higher than that for middle school students (17.0%) ( χ 2=50.35, P <0.01). The detection rates of depressive symptoms among middle school students with a history of childhood maltreatment and poor sleep quality were 45.8% and 44.0%, respectively. Multivariate Logistic regression analysis showed that compared to students without a history of childhood maltreatment, students with a history of childhood maltreatment had a higher risk of depressive symptoms ( OR =4.49，95% CI =3.31~ 6.09 , P <0.01);students with poor sleep quality had a higher risk of depressive symptoms than students with good sleep quality ( OR = 5.99，95% CI =4.37~8.22, P <0.01).The interaction results showed that the presence of childhood maltreatment and poor sleep quality had an additive interaction on the occurrence of depression in middle school students. Compared with students without childhood maltreatment and having good sleep quality, students with childhood maltreatment and poor sleep quality had a 22.49 times higher risk of developing depression ( OR =22.49，95% CI =14.22~35.59, P <0.01). Conclusion Depressive symptoms among middle school students are associated with childhood maltreatment and poor sleep quality, and there is an additive interaction between childhood maltreatment and poor sleep quality on the impact of depressive symptoms.

Objective: To analyze the relationship between parental psychological control and Internet Gaming Disorder (IGD) among junior high school students, so as to provide evidence for preventing IGD development in adolescents. Methods: From August 2019 to February 2020, a survey was conducted among 1 169 junior high school students from three middle schools in Xian using stratified cluster sampling. The Parental Psychological Control Scale and IGD Scale were administered to assess parental psychological control and IGD prevalence. Univariate and binary Logistic regression analyses were used to explore IGD risk factors and their correlation with parental psychological control. Results: The detection rate of IGD in middle school students was 19.9%(184/1 169). Multivariate Logistic regression revealed that compared to those with lower parental psychological control scores(≤21 points), students with higher parental psychological control scores (>21 points) had a higher risk of IGD (OR=1.82, 95%CI=1.21-2.74), a 1.58fold higher risk of selfperceived gaming addiction (95%CI=1.07-2.30), as well as reduced likelihood of seeking external help to reduce gaming time (OR=0.66, 95%CI=0.47-0.94) (P<0.05). Conclusions Parental psychological control may elevate the risks of IGD and selfperceived addiction while diminishing proactive helpseeking behaviors to reduce gaming time. Parents should enhance communication with adolescents and provide positive guidance to mitigate potential gamingrelated harms.

Xiang thinking is a cognitive approach that reflects the relationships between phenomena and their underlying principles by analyzing their external manifestations through methods such as analogy， reasoning， deduction， and symbolism. This article applied xiang thinking to analyze the etiology and pathogenesis of "wind， fire， phlegm， and blood stasis" in stroke， thereby exploring its impact on the principles of syndrome differentiation and treatment of this condition. Meanwhile， the article traced the construction process of xiang thinking， and interpreted the concept of "toxin pathogen" in traditional Chinese medicine from four perspectives， state， attribute， origin， and law. Furthermore， the relationship between the process of constructing xiang thinking and the origin of etiology， identification methods， pathogenesis evolution， and treatment strategies for stroke with syndrome of combined blood stasis and toxin was explored， so as to provide insights into research on the etiology and pathogenesis of stroke， as well as clinical diagnosis and treatment approaches.

ObjectiveTo investigate the correlation of the serum levels of aminotransferases and their ratios with liver inflammation activity in pediatric chronic hepatitis B （pCHB） patients， and to provide a basis for selecting the dominant population for treatment. MethodsThis study was conducted among 1 267 pCHB patients who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from January 2010 to August 2022 and these patients did not receive antiviral therapy. The patients were analyzed in terms of demographic features， blood routine， blood biochemistry， HBV serological markers， and liver biopsy data. According to liver inflammation activity based on liver biopsy， the patients were divided into no or mild inflammation activity （G0‍ ‍—‍ ‍G1） group and significant inflammation activity （G2‍ ‍—‍ ‍G4） group. The serum levels of aminotransferases and their ratios were compared between groups， and their correlation with liver inflammation activity in pCHB patients was analyzed. Additionally， the patients were stratified by the age， and the relationship between serum aminotransferase levels and liver inflammation activity was analyzed in each age group. For comparison of continuous data between two groups， the independent samples t-test was used when the data were normally distributed， while the Mann-Whitney U test was used when the data were not normally distributed； the chi-square test was employed for comparison of categorical data between two groups. A Spearman’s correlation analysis was performed for correlation assessment. ResultsAmong the 1 267 pCHB patients， there were 468 （36.9%） in the G0‍ ‍—‍ ‍G1 group and 799 （63.1%） in the G2‍ ‍—‍ ‍G4 group， and there were significant differences between the two groups in the levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， AST/ALT ratio， gamma-glutamyl transpeptidase （GGT）， total bilirubin， direct bilirubin， HBeAg quantification， low-density lipoprotein， and platelet count （PLT） （all P<0.05）. The correlation analysis showed that liver inflammation activity was negatively correlated with PLT and low-density lipoprotein （both P<0.05） and was positively correlated with GGT， total bilirubin， direct bilirubin， and HBeAg titer （all P<0.05）， while it was not significantly correlated with ALT， AST， and AST/ALT ratio （all P>0.05）. In the 0‍ ‍—‍ ‍12 years group， the 13‍ ‍—‍ ‍18 years male group， and the 13‍ ‍—‍ ‍18 years female group， liver inflammation activity aggravated with the increases in the serum levels of ALT and AST， and there were significant differences between groups （all P<0.05）. In the 0‍ ‍—‍ ‍12 years group， there was a significant difference in significant liver inflammation activity between the AST/ALT ratio >1 group and the AST/ALT ratio ≤1 group （P<0.001）. Among the 1 267 patients， 447 （35.28%） had an ALT level of <2×upper limit of normal （ULN）， among whom 196 （43.85%） had G≥2 liver inflammation， accounting for 15.47% of all children enrolled. ConclusionLiver inflammation activity is not significantly correlated with ALT， AST， and AST/ALT ratio in pCHB patients， suggesting that the serum levels of aminotransferases cannot truly reflect liver inflammation activity in pCHB patients with an aminotransferase level of <2×ULN. In clinical practice， liver biopsy should be performed for children with an aminotransferase level of <2×ULN to clarify whether antiviral therapy should be performed.

The intervention and prevention of perioperative hypothermia is not only reflected in the technical level, but also reveals the important role of humanistic care in the whole intervention work. If perioperative patients have hypothermia, it is likely to cause a series of complications such as postoperative shivering, which seriously threatens the life safety of patients. Prevention and intervention was based on a comprehensive understanding of the causes and hazards of hypothermia, especially the impact on the lives of the elderly. Effective supervision was implemented in the whole process of operation, such as dynamic monitoring of vital signs including body temperature, followed by room temperature regulation, body temperature protection and preoperative and postoperative psychological nursing. At this time, the sense of responsibility, good humanistic care of medical staff are of positive significance to effectively prevent and reduce the probability of perioperative hypothermia and accelerate the postoperative rehabilitation of patients.

Objective:To predict Chinese materia medica that may prevent and treat coronary microvascular dysfunction (CMD) by identifying disease core targets.Methods:CMD- related targets were obtained through GeneCards and OMIM databases. Subnetworks were extracted by using MCODE plugin in Cytoscape 3.9.1. Core targets of subnetworks were obtained by using cytoNCA plugin. GO function and KEGG pathway enrichment analysis for core targets were performed by using Metascape. Coremine Medical database was used to match targets with Chinese materia medica. Obtained Chinese materia medica was screened, and their properties and tastes, meridians and efficacy categories were under statistics.Results:Totally 3 859 disease-related targets were screened and five subnetworks were obtained. An in-depth study of MCODE1 yielded ten core targets, including IL-1β, IL6, TNF, STAT3, AKT1, ACTB, VEGFA, GAPDH, TP53, and ALB. GO functional enrichment analysis showed that these core targets were mainly involved in biological processes, such as positive regulation of gene expression, positive regulation of transcription, DNA template, and negative regulation of gene expression. KEGG pathway enrichment analysis identified 67 signaling pathways, including the AGEs-RAGE signaling pathway, HIF-1 signaling pathway, adipocytokine signaling pathway, fluid shear stress, and atherosclerosis. The researchers identified 36 kinds of Chinese materia medica associated with the ten core targets, including Salviea Miltiorrhizae Radix et Rhizoma, Chuanxiaong Rhizoma, Carthami Flos, Paeoniae Radix Rubra, Coptidis Rhizoma, Ginseng Radix et Rhizoma, Ophiopogonis Radix, Schisandrae Chinensis Fructus, Cinnamomi Cortex, Nelumbinis Semen, and Valerianae Jatamansi Rhizoma et Radix among 880 herbs.Conclusion:This study predicts 36 kinds of Chinese materia medica that have the effect of preventing and treating CMD, which can provide research ideas for the development of new drugs.

Objective To investigate the risk factors for postoperative pulmonary infection in pa-tients undergoing liver transplantation.Methods Clinical data of 1 358 patients who underwent liver trans-plantation for the first time from June 2005 to June 2013 at three clinical medical centers were retrospectively analyzed.Patients were divided into two groups according to whether or not they developed lung infection within 30 days after surgery:the infection group and the non-infection group.General,intrao-perative and postoperative data were collected,and risk factors for pulmonary infection after liver transplan-tation were analyzed using univariate analysis and binary logistic regression.Results Lung infections after liver transplantation occurred in 316 patients(23.3%),of whom 21 patients(6.7%)died.Compared with the non-infection group,the proportion of preoperative diagnosis of chronic severe hepatitis,hepatocellular carcinoma,hepatitis C cirrhosis,congenital liver disease and liver failure,preoperative combined hepatore-nal syndrome,hepatic coma and diabetes mellitus,preoperative creatinine concentration were significantly increased in the infection group(P＜0.05),preoperative total protein and albumin concentrations were significantly decreased(P＜0.05),and the duration of the hepatic-free period,the duration of postoperative awakening,and the duration of postoperative extubation were significantly prolonged(P＜0.05),intraoperative blood loss was significantly increased(P＜0.05),intraoperative urine output was significantly decreased(P＜0.05),the proportion of intraoperative phenylephrine,atropine,lidocaine,and furosemide drugs were significantly decreased(P＜0.05),and postoperative mortality rate was signifi-cantly increased in the infection group(P＜0.05).The results of binary logistic regression analysis showed that chronic severe hepatitis,hepatitis C cirrhosis,liver failure,preoperative diabetes mellitus,intraopera-tive blood loss＞1 900 ml,and postoperative awakening time＞7.3 hours were the risk factors for postoper-ative pulmonary infections in liver transplant patients,and the surgical method(classical non-transfusion in situ liver transplantation),the use of lidocaine during surgery,preoperative total protein＞64.6 g/L,and intraoperative urine volume＞1 800 ml were protective factors for postoperative pulmonary infections in liver transplantation patients.Conclusion Preoperative diagnosis of chronic severe hepatitis,hepatitis C cirrho-sis,liver failure,preoperative combined diabetes mellitus,intraoperative blood loss＞1 900 ml,and post-operative awakening time＞7.3 hours are risk factors for pulmonary infection after liver transplantation.
