BackgroundAnxiety disorder is a common mental disorder, with its prevalence showing a continuous upward trend, significantly affecting the quality of life and social function of patients. Due to the lack of objective and reliable biomarkers in clinical practice, the early identification and treatment of anxiety disorder have been somewhat limited. Plasma proteins have the potential to serve as biomarkers for mental diseases, however, the causal relationship between them and anxiety disorder remains unclear. ObjectiveTo identify the plasma proteins that have a causal relationship with anxiety disorders, and to elucidate the associated biological pathways, in order to provide references for the search for biomarkers of anxiety disorders and the exploration of potential therapeutic targets. MethodsBased on the protein quantitative trait locus (pQTL) data of 4 907 plasma proteins covering 35 559 Icelandic individuals from the deCODE database, and the genome-wide association studies (GWAS) data of 50 486 patients with anxiety disorders and 330 460 healthy controls, the inverse-variance weighted (IVW) method was used as the main analysis method, supplemented by MR-Egger method, weighted median method, simple model method, and weighted model method for bidirectional Mendelian randomization analysis. Enrichment analysis of gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways was conducted for the related proteins. Sensitivity analysis was performed using Cochran's Q test, MR-Egger intercept test, MR-PRESSO test, and leave-one-out analysis to evaluate the robustness of the results. ResultsA total of 10 plasma proteins were identified as significantly associated with anxiety disorders. Among these, SPATA9 (OR=0.856, 95% CI: 0.784–0.934, P<0.01) and PDE5A (OR=0.911, 95% CI: 0.864–0.961, P<0.01) were identified as protective factors, while CRYGD (OR=1.209, 95% CI: 1.095–1.334, P<0.01), BTN3A3 (OR=1.045, 95% CI: 1.018–1.073, P<0.01), SERPINB13 (OR=1.102, 95% CI: 1.040–1.168, P<0.01), ERBB4 (OR=1.283, 95% CI: 1.109–1.484, P<0.01), LSAMP (OR=1.096, 95% CI: 1.037–1.158, P<0.01), ICOSLG (OR=1.283, 95% CI: 1.104–1.490, P<0.01), DNAJB11 (OR=1.172, 95% CI: 1.076–1.277, P<0.01), and TREML1 (OR=1.115, 95% CI: 1.054–1.179, P<0.01) were identified as risk factors. The sensitivity analysis showed that the results were robust, with no heterogeneity (Cochran's Q test P>0.05) or pleiotropy (MR-Egger intercept test P>0.05). Enrichment analysis indicated that these plasma proteins were enriched in biological processes such as T-cell signal transduction, lymphocyte proliferation, cell membrane structure and synaptic function, as well as the intestinal immune network that produces IgA and the ErbB signaling pathway. ConclusionThis study identified 10 plasma proteins associated with anxiety disorders. The functions of these plasma proteins involve multiple biological processes such as neural development and immune regulation.

Objective To systematically evaluate the efficacy and safety of video-assisted thoracoscopic surgery (VATS) with different numbers of ports in the treatment of spontaneous pneumothorax. Methods We conducted a comprehensive search of CNKI, PubMed, The Cochrane Library, Web of Science, EMbase, Wanfang Data, and the Chinese Medical Journal Full-text Database for clinical controlled trials on VATS with different port numbers for spontaneous pneumothorax, from their inception to March 2023. Two researchers independently screened the literature and assessed its quality.The Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of cohort and case-control studies, and the Cochrane risk-of-bias tool was used to evaluate randomized controlled trials (RCT). Meta-analysis was performed using RevMan 5.4.1 software. Results A total of 107 studies were included, comprising 35 RCT, 2 cohort studies, and 70 case-control studies. All cohort and case-control studies included in the analysis had NOS scores≥7. The meta-analysis revealed that compared to two-port VATS (2P-VATS) and three-port VATS (3P-VATS), single-port thoracoscopic surgery (SPTS) was associated with less intraoperative blood loss (SMD=–1.58, 95%CI: –1.93 to –1.22, P<0.001; and SMD=–1.59, 95%CI: –2.03 to –1.14, P<0.001, respectively), shorter postoperative hospital stay (SMD=–1.05, 95%CI: –1.29 to –0.82, P<0.001; and SMD=–1.08, 95%CI: –1.39 to –0.77, P<0.001), shorter duration of postoperative chest tube drainage (SMD=–0.75, 95%CI: –1.00 to –0.50, P<0.001; and SMD=–1.23, 95%CI: –1.72 to –0.75, P<0.001), fewer postoperative complications (OR=0.34, 95%CI: 0.26 to 0.45, P<0.001; and OR=0.47, 95%CI: 0.33 to 0.68, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P<0.05). The operative time for SPTS was shorter than that for 2P-VATS (SMD=–0.53, 95%CI: –0.90 to –0.16, P=0.005) but showed no significant difference compared to 3P-VATS (P=0.21). When comparing 2P-VATS with 3P-VATS, 2P-VATS demonstrated less intraoperative blood loss (SMD=–1.02, 95%CI: –1.81 to –0.22, P=0.01), shorter postoperative hospital stay (SMD=–0.59, 95%CI: –1.11 to –0.06, P=0.03), shorter duration of chest tube drainage (SMD=–0.46, 95%CI: –0.85 to –0.08, P=0.02), fewer postoperative complications (OR=0.36, 95%CI: 0.22 to 0.59, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P≤0.05). Conclusion Both SPTS and 2P-VATS are effective and safe surgical options for spontaneous pneumothorax, deserving further promotion and application in clinical practice. However, due to limitations in the quantity and quality of the included studies, more large-sample, high-quality research is needed to validate these findings.

To explore the advantages of traditional Chinese medicine (TCM) and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications (DMC), refine key pathophysiological insights and treatment principles, and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine, hosted by the China Association of Chinese Medicine, was held in Beijing, 2024. Experts in TCM, Western medicine, and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis, diagnostic and treatment challenges, and mechanism research related to DMC, ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development, research prioritization, and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM, strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Chinese Journal of School Health 2026;47(1):65-69
Objective:
To explore the effects of personality and sleep quality with psychological distress of junior and senior high school stduents, so as to provide a reference basis for precise interventions of junior and senior high school students mental health.
Methods:
In October 2023, a convenience sampling method was used to select 9 034 students aged 12-17 from Shiyan City as the study subjects. The Pittsburgh Sleep Quality Index (PSQI) and Kessler Psychological Distress Scale (K10) were used to collect information on sleep quality and psychological distress of junior and senior high school stduents. Between group comparison was conducted by using t-test and Chi-square test. Generalized linear models were employed to analyze the interaction and joint effects of personality and sleep quality on psychological distress.
Results:
The generalized linear model analysis showed that the interaction between personality and sleep quality on psychological distress was statistically significant of junior and senior high school students(effect size=0.80, P <0.01). The general linear model analysis indicated that, after adjusting for variables such as age, gender, screen time, and daily sitting time with the extroverted and good sleep quality group as the reference, the introverted and poor sleep quality group had the largest mean difference in psychological distress scores (difference=0.51, P <0.05). When stratified by sleep quality, psychological distress scores were higher in the introverted and neutral personality groups with both poor and good sleep quality compared to the extroverted group (poor sleep quality: introverted difference=3.71, neutral difference=1.14; good sleep quality: introverted difference=2.23, neutral difference=0.57, all P < 0.05). When stratified by personality, psychological distress scores were higher in the poor sleep quality groups for introverted, neutral, and extroverted individuals compared to their good sleep quality counterparts (differences=8.66, 7.83, 7.34, all P < 0.05 ).
Conclusions
Personality and sleep quality have interactive and joint effects on psychological distress of junior and senior high school stduents. Personalized psychological interventions should be developed based on personality and sleep quality.

Objective To systematically evaluate the efficacy and safety of single-port thoracoscopic surgery (SPTS) in the treatment of spontaneous pneumothorax. Methods Computer searches were conducted in PubMed, The Cochrane Library, Web of Science, Embase, CNKI, WanFang, and the Chinese Medical Association databases to collect randomized controlled trials (RCTs) and cohort studies on the comparison of efficacy and safety of SPTS and three-port thoracoscopic surgery (TPTS) for the treatment of spontaneous pneumothorax from their inception to March 2024. The Cochrane RCT bias risk assessment tool and the Newcastle-Ottawa Scale (NOS) were used to assess the quality of RCTs and cohort studies, respectively. Meta-analysis was performed using RevMan 5.4.1. Results A total of 68 studies were included, comprising 23 RCTs and 45 cohort studies with a total of 5403 patients. The NOS scores of the cohort studies were 7-8 points. Meta-analysis results showed that compared with TPTS, SPTS had less intraoperative blood loss [SMD=−1.58, 95%CI (−1.93, −1.22), P<0.001], shorter postoperative hospital stay [SMD=−1.05, 95%CI (−1.29, −0.82), P<0.001], shorter postoperative drainage tube placement time [SMD=−0.75, 95%CI (−1.00, −0.50), P<0.001], fewer postoperative complications [OR=0.34, 95%CI (0.26, 0.45), P<0.001], fewer postoperative recurrences [OR=0.48, 95%CI (0.32, 0.72), P<0.001], and less pain at 24, 48, and 72 h postoperatively [SMD=−1.71, 95%CI (−2.13, −1.30), P<0.001; SMD=−1.70, 95%CI (−2.35, −1.06), P<0.001; SMD=−1.72, 95%CI (−2.16, −1.29), P<0.001]. Conclusion SPTS is safe and effective in the treatment of spontaneous pneumothorax with high clinical value and can be further promoted in clinical practice. Considering the limitations in the number and quality of included studies, researches with larger sample sizes and higher quality are needed to validate the above conclusions.

ObjectiveTo investigate the value of liver stiffness measurement (LSM) and spleen stiffness measurement (SSM) measured by two-dimensional shear wave elastography (2D-SWE) in the diagnosis of severe portal hypertension (SPH) and high-risk varices (HRV), and to provide a basis for noninvasive assessment of portal hypertension. MethodsA prospective study was conducted among 78 patients with cirrhotic portal hypertension who were treated in Liver Research Center of Beijing Friendship Hospital, Capital Medical University, from December 2019 to April 2023. According to hepatic venous pressure gradient (HVPG), the patients were divided into 6 mmHg≤HVPG<12 mmHg group, 12 mmHg≤HVPG<20 mmHg group, and HVPG ≥20 mmHg group. All patients underwent gastroscopy and 2D-SWE within 1 week after HVPG measurement, and SWE-LSM and SWE-SSM measured by 2D-SWE were recorded. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between multiple groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. With HVPG and gastroscopy findings as the gold standard, the receiver operating characteristic (ROC) curve was plotted and the area under the ROC curve (AUC) was calculated to evaluate diagnostic performance, while the DeLong test was used for comparison of AUC. The Pearson or Spearman correlation analysis was used to investigate the correlation between variables, and the linear regression analysis and the Logistic regression analysis were used to investigate the influencing factors for HVPG and HRV. ResultsThe mean HVPG was 18.1±6.4 mmHg for the patients enrolled in this study, and HRV was observed in 62 patients (79.5%). Both SWE-LSM and SWE-SSM were significantly positively correlated with HVPG (r=0.413 and 0.633, both P<0.001), with an AUC of 0.812 and 0.902, respectively, in the diagnosis of HVPG≥12 mmHg and an AUC of 0.804 and 0.789, respectively, in the diagnosis of HVPG≥20 mmHg (all P>0.05). The multivariate linear regression analysis showed that SWE-SSM was an independent influencing factor for HVPG (β=0.17, P<0.001). In the diagnosis of HRV, only SWE-SSM showed a significant positive correlation with HRV (r=0.432, P<0.001), with a better diagnostic performance than SWE-LSM in terms of AUC (0.808 vs 0.642, Z=2.775, P=0.006). The multivariate Logistic regression analysis showed that platelet count was an independent influencing factor for HRV (odds ratio=0.97, P=0.014). ConclusionSWE-SSM is closely correlated with both HVPG and HRV, showing a good performance in the diagnosis of SPH and HRV, and therefore, it is expected to become an effective noninvasive tool for assessing portal hypertension.

ObjectiveTo investigate the mechanism by which Shengjiang Pingchuan Zhike pills (SPZP) alleviate airway injury in the rat model of cough variant asthma (CVA) via regulating autophagy through activating the adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR)/Unc-51-like autophagy activating kinase 1 (ULK1) signaling pathway based on transcriptomics, thus providing experimental evidence for the clinical application of SPZP. MethodsForty SPF-grade SD rats were enrolled in the present study and randomly via the random number table method assigned into four groups: a blank group, a model group, a SPZP (2 160 mg·kg-1·d-1) group, and a positive drug (montelukast sodium, MTL, 0.9 mg·kg-1·d-1)group, with 10 rats in each group. After one week of adaptive feeding, the rat model of cough variant asthma (CVA) was established by two-week sensitization with ovalbumin (OVA) and aluminium hydroxide, followed by capsaicin atomization challenge. Rats in the blank group received an equal volume of normal saline during modeling. Upon successful modeling, rats in the SPZP group and positive drug group were administrated with SPZP suspension and MTL solution, respectively, while those in the blank and model groups received the same dose of normal saline by gavage. The whole intervention lasted for 21 consecutive days. After the intervention, general behaviors of rats in each group were observed. Pulmonary function indicators were subsequently detected. Hematoxylin-eosin (HE) staining was performed to visualize the pathological morphology of the lung tissue, and periodic acid-Schiff (PAS) staining was adopted to evaluate airway mucus secretion. Transcriptomic sequencing was conducted to screen differentially expressed genes in the lung tissue across groups. The levels of inflammatory cytokines including interleukin (IL)-4, IL-5, immunoglobulin E (IgE), and interferon-γ (IFN-γ) in the bronchoalveolar lavage fluid (BALF) were quantified by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence staining was used for detecting the co-localization of autophagy-related protein Beclin-1 and phosphorylated mammalian target of rapamycin (p-mTOR). Transmission electron microscopy was employed to count autophagosomes and observe mitochondrial morphological changes in the lung tissue. Western blot assay was utilized to measure the expression levels of AMPK/mTOR/ULK1 axis-related proteins, including AMPK, phosphorylated adenosine monophosphate-activated protein kinase (p-AMPK), mTOR, phosphorylated mammalian target of rapamycin (p-mTOR), ULK1, and phosphorylated Unc-51-like autophagy activating kinase 1 (p-ULK1) as well as the autophagy biomarkers Beclin-1 and selective autophagy adaptor protein p62 in lung specimens. ResultsCompared with the blank group, the model group exhibited markedly elevated cough frequency accompanied by wheezing and stridor, dull fur, poor mental activity, diminished motor activity, accelerated respiratory rate, and weakened sensory response and mobility to external stimuli, accompanied by a declining tendency of body mass. Meanwhile, the model group exhibited decreased dynamic lung compliance, increased airway resistance (P<0.01), severe pathological damage and excessive mucus secretion in the lung tissue (P<0.01), and elevated levels of IL-4, IL-5, and IgE and declined level of IFN-γ in the BALF (P<0.01). Ultrastructural observation revealed damaged mitochondrial morphology and a sharp reduction in the number of autophagosomes in the lung tissue. In addition, the expression of p-AMPK, p-ULK1, and Beclin-1 were downregulated, whereas p-mTOR and p62 were highly expressed (P<0.05, P<0.01) in the model group. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses demonstrated significant enrichment of AMPK, mTOR, and autophagy-related pathways. Compared with the model group, both the positive drug group and SPZP group obtained visible improvements in general behavioral manifestations and obvious recovery of pulmonary function indicators (P<0.05), alleviated pulmonary pathological lesions and suppressed excessive airway mucus secretion (P<0.05), recovered levels of inflammatory cytokines in the BALF (P<0.05), restored mitochondrial morphology, increased autophagosomes, upregulated expression levels of p-AMPK, p-ULK1, and Beclin-1, and downregulated expression levels of p-mTOR and p62 (P<0.05). ConclusionSPZP can effectively ameliorate airway inflammation and improve the pulmonary function in the rat model of CVA by activating the AMPK/mTOR/ULK1 signaling pathway, enhancing autophagy in the lung tissue, and inhibiting excessive airway mucus secretion and immune inflammatory imbalance.

Objective:
To investigate the association between parenting styles and attention deficit hyperactivity disorder (ADHD) in preschool children,so as to provide a basis for family based interventions for ADHD in the population.
Methods:
Between August and December 2023, a random cluster sampling method was used to recruit 6 454 preschool children from 60 kindergartens in two counties/districts in Wuhu City, Anhui Province. The Swanson, Nolan, and Pelham Rating Scale, version IV was used to assess ADHD symptoms, and the Caregiver Parenting Style Questionnaire was applied to collect data on parenting styles. Multivariate Logistic regression was used to analyze the associations between parenting styles and ADHD subtypes.
Results:
Among the preschool children, 235 were screened positive for ADHD, with a positivity rate of 3.64%. Parenting style scores were as follows:indulgent parenting for 8.00 (7.00, 10.00), authoritative parenting for 38.00 (33.00, 41.00), permissive parenting for 14.00 (11.00, 17.00), authoritarian parenting for 17.00 (14.00, 20.00), and inconsistent parenting 10.00 (7.00, 12.00). Multivariate Logistic regression analysis showed that, after adjustment for confounding factors such as childrens sex, age, and family characteristics, preschool children with authoritarian parenting style were associated with higher odds of hyperactive ( OR = 1.13 ) and combined ADHD subtypes ( OR =1.11), while those with inconsistent parenting style were associated with higher odds of the inattentive subtype ( OR =1.09) (all P <0.01). Indulgent, democratic and permissive parenting styles showed no statistically significant associations with any ADHD subtype ( OR =1.02-1.07, 0.98-1.00, 1.01-1.03, all P >0.05).
Conclusions
Parenting styles are closely associated with the occurrence and subtypes of ADHD in preschool children. Authoritarian and inconsistent parenting styles are potential risk factors for ADHD in preschool children, and modifying adverse parenting styles may serve as an important strategy for family based interventions for ADHD in preschool children.

Objective:This study aimed to analyze the genetic variation of the human papillomavirus (HPV) type 39 genomes and to predict and screen the dominant T-cell and B-cell epitopes of the viral early proteins (E1, E2, E6, E7) and late proteins (L1, L2).Methods:A total of 70 full-length sequences of HPV39 variants were retrieved from the clinical samples and the National Center for Biotechnology Information (NCBI) to construct a phylogenetic tree, analyze genetic polymorphisms, and predict the physicochemical properties of the viral proteins. Next, T-cell and B-cell epitopes were predicted using IEDB and ABCpred, and potential dominant epitopes were further selected based on parameters such as the secondary structure of the epitope region, peptide flexibility, hydrophilicity, surface accessibility and antigenicity. Finally, a homology analysis of the potential dominant epitopes was performed with 12 high-risk HPV types.Results:HPV39 variants from different sources can be clustered into two lineages (A and B), each exhibiting distinct mutation patterns. The mutation rate was the highest in E7 and the lowest in E1 among the different viral genes. However, these nucleotide/amino acid mutations did not significantly impact the physicochemical properties of the viral proteins. After prediction and screening, 5 and 6 potential dominant B-cell epitopes were identified in both L1 and L2, respectively. E1, E2, E6, and E7 yielded 18, 10, 4, and 1 potential dominant HLA-I restricted T-cell epitopes, respectively. Additionally, E1, E2, and E6 yielded 7, 3, and 2 potential dominant HLA-II restricted T-cell epitopes, respectively. Homology analysis indicated that T-cell dominant epitopes in E1, E2, and E6, as well as B-cell epitopes in L2, showed high homology (93%-100%) with HPV68, HPV33, HPV45, and HPV59.Conclusions:Bioinformatics analysis and prediction revealed that HPV39 variants can be clustered into two main evolutionary branches, A and B, each exhibiting a specific mutation pattern. The viral proteins contain potential dominant T-cell and B-cell epitopes that can be further investigated, providing valuable theoretical support for the development of HPV39-related peptide-based vaccines and therapeutics.

This study aims to retrospectively analyze the distribution of human papillomavirus (HPV) subtypes and cervical lesion characteristics in female patients at Shenzhen Cancer Hospital. Adopting a retrospective observation research method. Using convenience sampling, the study subjects were selected from women who visited the Shenzhen Hospital of the Chinese Academy of Medical Sciences Cancer Hospital from September 2020 to December 2023.HPV genotyping was performed on cervical exfoliated cells from 6 402 women using rapid nucleic acid hybridization. Additionally, thinprep cytologic test (TCT) was conducted on 845 HPV-positive samples. High-grade squamous intraepithelial lesions (HSIL) were further classified as cervical intraepithelial neoplasia grades 2 or 3 (CIN2/3) through histopathological examination via cervical biopsy or conization. Data were statistically analyzed using χ2 test and two-sided test. The results showed that HPV testing identified 1 205 HPV-positive cases, with an overall positivity rate of 18.8% (1 205/6 402). Among these, the positivity rate for high-risk(HR) HPV was 14.34%(918/6 402), low-risk(LR) HPV was 3.58%(229/6 402), and other HPV types accounted for 0.91% (58/6 402). The most prevalent high-risk HPV subtypes were HPV16, HPV52, HPV39, HPV58, and HPV53, with positivity rates of 3.16% (202/6 402), 2.92% (187/6 402), 1.34% (86/6 402), 1.30%(83/6 402), and 1.05%(67/6 402), respectively. HPV16 had the highest infection rate in cervical malignancies, CIN3, and CIN2/3 groups, with rates of 53.18%(92/173), 47.37%(27/57), and 34.78%(8/23), respectively. Conversely, HPV52 showed the highest infection rate in the atypical squamous cells(ASC), Low-grade squamous intraepithelial lesion(LSIL), and CIN2 groups, at 29.68%(19/64), 23.50%(43/183), and 37.93%(11/29), respectively. Among 845 HPV positive female patients, the pathological diagnosis was squamous cell carcinoma, accounting for 22.13% (187/845), and adenocarcinoma accounting for 1.42%(12/845). HPV infection rates increased with age: 16.39%(97/592) in the ≤30 age group, 14.46%(301/2 082) in the 31-40 group, 17.26%(318/1 842) in the 41-50 group, 23.98%(300/1 251) in the 51-60 group, and 29.76%(189/635) in those over 60. In conclusion,in the female patient population of the Shenzhen Hospital of the Chinese Academy of Medical Sciences Cancer Hospital, HPV16 is associated with cervical cancer and high-grade cervical lesions, while HPV52 is related to low-to moderate-grade cervical lesions. Enhancing HPV screening among adult women is essential for preventing cervical cancer and associated lesions.
