ObjectiveThis study aims to analyze animal models of anxiety disorder based on the clinical characteristics of anxiety disorder in traditional Chinese and Western medicine， systematically assess the clinical compatibility， and provide suggestions for the construction of animal models with a high degree of clinical compatibility between traditional Chinese and Western medicine. MethodsRelevant literature on animal models of anxiety disorder was retrieved from global databases. Scoring scales were developed according to the etiology， pathogenesis， and diagnostic criteria of anxiety disorder in both traditional Chinese and Western medicine. The animal models of anxiety disorder in the literature were analyzed， and their clinical compatibility was systematically assessed to identify reference-worthy models. ResultsThe average clinical compatibility of existing animal models of anxiety disorder was 42.13% for traditional Chinese medicine and 50.94% for Western medicine. Among these， the chronic unpredictable mild stress （CUMS） model had the highest compatibility with both traditional Chinese and Western medicine. However， current models rarely reflect the clinical syndromes of traditional Chinese medicine in depth， and show limitations in syndrome differentiation. ConclusionThe existing animal models of anxiety disorder are mostly established using single-factor approaches， which fail to comprehensively simulate the onset process and physiopathological characteristics of anxiety disorder. These models also neglect the syndrome-based indicators emphasized in traditional Chinese medicine. In the future， the model development should incorporate the clinical characteristics of syndromes in both traditional Chinese and Western medicine， establish standardized evaluation criteria for anxiety disorder models， and utilize multifactorial approaches to enhance the representativeness of animal models in traditional Chinese medicine.

Objective: To explore the association between serum nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), NIMA-related kinase 7 (NEK7) and pulmonary fibrosis among patients with coal workers' pneumoconiosis, so as to provide a basis for the assessment of the degree of pulmonary fibrosis. Methods: Coal workers with pneumoconiosis hospitalized in the Second Affiliated Hospital of Xuzhou Medical University from July 2022 to July 2023 were selected by simple random sampling. Data such as age, stage of pneumoconiosis, and dust-exposure duration were collected through the hospital's electronic medical record management system. Venous blood was collected to detect the levels of serum NLRP3 and NEK7. High-resolution computed tomography (HRCT) image data of the chest were obtained through the hospital's imaging reporting system. The left and right lungs were divided into 6 pulmonary regions according to the upper, middle, and lower parts. The pulmonary fibrosis score was quantified according to the proportion of the pulmonary area occupied by HRCT manifestations of pulmonary fibrosis, including reticular shadows, pleural and interlobular septal thickening, traction bronchiectasis, and honeycombing. The association between the levels of serum NLRP3, NEK7, and pulmonary fibrosis was analyzed using a multiple linear regression model. Results: A total of 81 patients with coal workers' pneumoconiosis were included, all of whom were male, with a mean age of (71.46±11.69) years. There were 48, 28, and 5 cases in stage Ⅰ, stage Ⅱ, and stage Ⅲ of pneumoconiosis pathological staging, accounting for 59.26%, 34.57%, and 6.17%, respectively. There were 45 cases of tunneling and coal mining, accounting for 55.56%. There were 41 cases with dust exposure years of ≥30 years, accounting for 50.62%. The median serum NLRP3 and NEK7 in patients with coal workers' pneumoconiosis were 2.01 (interquartile range, 2.33) ng/mL and 0.98 (interquartile range, 0.83) ng/mL. The median score of pulmonary fibrosis was 5.00 (interquartile range, 5.50) points. After adjusting for age, stage of pneumoconiosis, type of work and dust-exposure duration, multiple linear regression analysis showed that serum NLRP3 (β'=0.649) and NEK7 (β'=0.346) were positively correlated with the pulmonary fibrosis score. Conclusion The increase in the levels of serum NLRP3 and NEK7 in patients with coal workers' pneumoconiosis is related to the increase in the degree of pulmonary fibrosis.

Objective:To investigate the efficacy and safety of endoscopic resection of infratemporal fossa mass and to determine the indications for surgery.Methods:A retrospective case series study was conducted, including a total of 29 patients who underwent endoscopic surgery to treat infratemporal fossa mass in the Department of Rhinology of Beijing Tongren Hospital, Capital Medical University, from April 2008 to December 2021. Ten males and 19 females were included in the study, with age of (46.5±13.7) years. Pre-and post-operative sinus CT, sinus or nasopharyngeal enhanced MRI were evaluated, respectively. The main outcome measurements were the total resection of mass and the incidence of surgery-related complications.Results:Among the 29 cases of infratemporal fossa mass, 22 were schwannomas, 3 were cysts, 2 were neurofibromas, 1 was pleomorphic adenoma and 1 was basal cell adenoma. Preoperative imaging showed well-defined lesion boundaries, and postoperative pathology confirmed the benign nature of all cases. The endoscopic transnasal approach was used in 28 patients, while the combination of the transnasal approach and the transoral approach was used in 1 patient. Complete tumor removal was achieved in all cases with a 100% resection rate. The average follow-up time was 38 months (7-168 months), and no tumor recurrence was observed.Conclusions:The Endoscopic transnasal approach is a safe and effective surgical approach for the treatment of benign tumors or masses in the infratemporal fossa.

Objective:To analyze the efficacy of endoscopic surgery for frontal sinus meningoencephalocele and cerebrospinal fluid (CSF) leaks, and to explore endoscopic surgical strategy.Methods:A total of 35 patients with frontal sinus meningoencephalocele and CSF leaks who underwent endoscopic transnasal surgery at Beijing Tongren Hospital, Capital Medical University between May 2007 and December 2023 were enrolled in this retrospective case series, including 29 males and 6 females, with the age of (35.23±15.76) years. High-resolution sinus CT and magnetic resonance cisternography were undertaken before surgery. The primary outcome measure was the success rate of endoscopic surgical repair. Statistical analysis was conducted using SPSS 27 and GraphPad Prism 8 software.Results:Of the 35 cases, 21 (60.0%) were traumatic, and 14 (40.0%) were non-traumatic. The most common defect was in the posterior frontal sinus wall (24 cases, 68.6%), with a defect size of (10.4±4.8) mm 2. Twenty-six cases (74.3%) underwent endoscopic transnasal Draf Ⅱa-Ⅲ frontal sinusotomy, and 9 cases (25.7%) underwent endoscopic transnasal Darf Ⅱb-Ⅲ frontal sinusotomy combined with frontal trephination. The average follow-up time was (84.72±57.42) months. The success rate of one-time endoscopic repair was 97.1% (34/35). One patient required a second procedure, resulting in an overall success rate of 100%. Thirty-three patients had a widely patent frontal sinus ostium postoperatively, while two experienced stenosis. Conclusions:Endoscopic surgery is effective for treating frontal meningoencephalocele and CSF leaks while preserving frontal sinus drainage. Combined frontal trephination is recommended for defects that are difficult to repair using the conventional transnasal approach.

Objective　To explore the characteristics of toxic heavy metal pollution in atmospheric PM2.5 (Particulate matter 2.5) during winter in Nanning City and to evaluate the health risks for the population. Methods　Atmospheric PM2.5 samples were continuously collected in the urban areas of Nanning from January to February 2019. The concentrations of seven toxic heavy metals, including cadmium (Cd), arsenic (As), chromium (Cr), lead (Pb), nickel (Ni), mercury (Hg), and manganese (Mn) in atmospheric PM2.5 were analyzed by X-ray fluorescence spectrometry. The pollution characteristics of toxic heavy metals were studied by geo-accumulation index and enrichment factor methods, and their health risks to children and adults were assessed using the health risk assessment model of the United States Environmental Protection Agency. Results　The mass concentration of atmospheric PM2.5 in Nanning in winter 2019 was (44±29) μg/m3, which was generally at a low level. Different degrees of pollution were found for Hg, Cd, As, Cr, and Pb in PM2.5, with Hg and Cd being more seriously polluted. Hg and Cd were highly enriched in PM2.5, followed by Pb with moderate enrichment. These three elements mainly originated from man-made pollution. As, Cr and Ni were mildly enriched and affected by both natural and anthropogenic sources. The non-carcinogenic risks were in the order of As>Pb>Hg>Cr>Cd>Mn>Ni. The total non-carcinogenic risks for the three populations were all less than 1, which is within acceptable limits. The carcinogenic risks were ranked as Cr>As>Cd>Ni, with Cr, As, and Cd posing carcinogenic risks to children and adults ranging from 1×10-6 to 1×10-4. Moreover, the total carcinogenic risks of heavy metals (Cr, As, Cd, and Ni) were higher than 1×10-4 for children, indicating a potential carcinogenic risk. Conclusions　The mass concentration of PM2.5 and heavy metal elements in Nanning City during the winter of 2019 was relatively low, but the pollution of heavy metals still exists. The non-carcinogenic risk of heavy metals is within an acceptable range, but the carcinogenic risk poses a potential danger to children.

Increased intestinal barrier permeability, leaky gut, has been reported in patients with autism. However, its contribution to the development of autism has not been determined. We selected dextran sulfate sodium (DSS) to disrupt and metformin to repair the intestinal barrier in BTBR T⁺tf/J autistic mice to test this hypothesis. DSS treatment resulted in a decreased affinity for social proximity; however, autistic behaviors in mice were improved after the administration of metformin. We found an increased affinity for social proximity/social memory and decreased repetitive and anxiety-related behaviors. The concentration of lipopolysaccharides in blood decreased after the administration of metformin. The expression levels of the key molecules in the toll-like receptor 4 (TLR4)-myeloid differentiation factor 88 (MyD88)-nuclear factor kappa B (NF-κB) pathway and their downstream inflammatory cytokines in the cerebral cortex were both repressed. Thus, "leaky gut" could be a trigger for the development of autism via activation of the lipopolysaccharide-mediated TLR4-MyD88-NF-κB pathway.

Objective: To evaluate the impact of bleomycin/etoposide/cisplatin (BEP) and paclitaxel/carboplatin (PC) chemotherapy regimens on the fertility and prognostic outcomes in malignant ovarian germ cell tumor (MOGCT) patients who underwent fertility-sparing surgery (FSS). Methods: A propensity score matching algorithm was performed between the BEP and PC groups. The χ2 test and the Kaplan-Meier method were used to compare the fertility outcome, disease-free survival (DFS) and overall survival (OS). The Cox proportional hazards regression analysis was used to identify risk factor of DFS. Results: We included 213 patients, 185 (86.9%) underwent BEP chemotherapy, and 28 (13.1%) underwent PC chemotherapy. The median age was 22 years (range, 8–44 years), and the median follow-up period was 63 months (range, 2–191 months). Fifty-one (29.3%) patients had a pregnancy plan, and 35 (85.4%) delivered successfully. In the before and after propensity score matching cohorts, there were no significant differences in spontaneous abortion, selective termination of pregnancy, during-pregnancy status, and live birth between the BEP and PC groups (p>0.05). Fourteen (6.6%) patients experienced recurrence, including 11 (5.9%) in the BEP group and 3 (10.7%) in the PC group. Four (1.9%) patients in the BEP group died. Kaplan-Meier analysis revealed no significant differences in DFS (p=0.328) and OS (p=0.446) between the BEP and PC groups, and the same survival results were observed in the after matching cohort. Conclusion The PC regimen is as safe as the BEP regimen for MOGCT patients with fertility preservation treatment, and no differences were observed in fertility and clinical prognosis.

Objective:To investigate the clinical and genetic characteristics of patients with late-onset subtypes (adolescent or adult) of Krabbe disease.Methods:The clinical data of 7 patients with Krabbe disease admitted to Shanghai Jiao Tong University Affiliated Sixth People′s Hospital and Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from September 2006 to June 2021 were analyzed and Sanger sequencing of the galactosylceramidase (GALC) gene (NM_000153) and detection of the activity of GALC were conducted. A total of 61 cases of Krabbe disease reported in domestic literature were reviewed and summarized.Results:Among the 7 patients with Krabbe disease, there were 4 males and 3 females. All of them had lower limb weakness or walking difficulty as the initial symptoms, and presented as spastic paraplegia. The symptoms were relatively mild in patients with late onset. There were 4 out of 5 patients undergoing magnetic resonance imaging examination, who showed abnormal signals: 2 had brain atrophy and the remaining 2 had white matter lesions. A total of 5 GALC gene mutations were detected by genetic analysis. Among these, c.1901T>C (p.L634S), c.908C>T(p.S303F) and c.461C>A(p.P154H) are known variants, while c.50_51insTT (p.M17Ifs) and c.1130delT(p.L337X) are novel variants reported for the first time in this paper.Conclusions:Krabbe disease is a rare neurodegenerative disease with phenotypic heterogeneity, which is inherited in an autosomal recessive mode. The severity of clinical manifestations of Krabbe disease is correlated with the age of onset.

Objective:To investigate the longitudinal changes and influencing factors of out-of-hospital functional exercise compliance in patients with lumbar disc herniation treated conservatively based on patient-based compliance curve (PBCC) .Methods:From April to September 2020, the convenient sampling method was used to select 88 patients with lumbar disc herniation treated conservatively in Hangzhou Hospital of Traditional Chinese Medicine as the research objects. The score of out-of-hospital functional exercise compliance questionnaire of patients with lumbar disc herniation was measured from the time of discharge, once every 2 weeks, and the PBCC of functional exercise was drawn after continuous measurement to the 24th week , taking time as independent variable ( x) and functional exercise compliance index as dependent variable ( y) . Univariate and multiple linear regression analyses were used to explore the influencing factors of 24-week compliance index. A total of 88 questionnaires were distributed, among which 3 patients withdrew due to surgery and 11 patients were lost to follow-up. A total of 74 valid questionnaires were finally recovered, with an effective recovery rate of 84.09% (74/88) . Results:Within 24 weeks of discharge, the PBCC formula of the total functional exercise score of patients was y=0.005 x3-0.196 x2+1.436 x+59.197 ( R2=0.898, F=26.517, P<0.01) . The PBCC formula of physical exercise was y=0.008 x3-0.337 x2+3.616 x+56.153 ( R2=0.878, F=21.570, P<0.01) . The formula of exercise effect supervision PBCC was y=-0.006 x3+0.309 x2-5.315 x+76.371 ( R2=0.910, F=30.458, P<0.01) . The PBCC formula of actively seeking advice was y=0.012 x3-0.460 x2+3.931 x+44.071 ( R2=0.865, F=19.217, P<0.01) . Except for the PBCC of effect supervision, the changes of other PBCC showed a trend of first increasing and then decreasing. The average compliance index in 24 weeks was (57.73±8.20) , the high peak appeared in the 4th week and the index was (64.08±8.91) . The low peak appeared in the 18th week and the index was (52.42±7.81) . The results of univariate analysis showed that there were statistically significant differences in the compliance level of rehabilitation exercise in patients with lumbar protrusion in different age, education level, course of lumbar protrusion, pain degree, accompanying symptoms, functional exercise methods and disease knowledge ( P<0.05) . The results of multiple linear regression analysis showed that the main influencing factors of functional exercise compliance of patients were disease knowledge, pain degree, course of lumbar protrusion and functional exercise method ( P<0.05) . Conclusions:The functional exercise compliance of lumbar disc herniation patients shows a horizontal "S" -like dynamic change. During the period of decreased compliance, regular rehabilitation guidance and health education, pain management and prevention of recurrence are necessary measures to improve functional exercise compliance of patients.

The liquid chromatography tandem mass spectrometry was used to detect the urinary proteomics of 223 residents aged 40-69 years old who participated in the National Upper Gastrointestinal Cancer Early Detection Program in Linqu County, Shandong Province from November 22 to December 7, 2018, and analyze the alcohol consumption related proteomic profiles and individual urinary protein. There were significant differences in urinary protein profiles between alcohol consumption group and non-alcohol consumption group. The expression of 26 urinary proteins was up-regulated and 20 urinary proteins were down-regulated in alcohol consumption group ( P<0.05). The differentially expressed proteins had enzyme inhibitor activity and phospholipid binding function, and mainly enriched in pathways involving proximal tubule bicarbonate regeneration, complement and coagulation cascade, and cholesterol metabolism. The protein expressions of complement factor I (CFI), angiotensin converting enzyme 2 (ACE2) and protein C inhibitor (SERPINA5) were positively correlated with daily alcohol consumption.
