Objective: To understand the current status of psychological sub health among secondary vocational school students and explore its related factors, so as to provide a scientific basis for improving their mental health. Methods: From September to December 2024, a convenience sampling method was used to conduct a questionnaire survey among 5 141 secondary vocational school students from 16 schools across 8 provinces and municipalities (Fujian, Chongqing, Guangdong, Guangxi, Hubei, Jiangxi, Shanghai, Zhejiang). A self designed questionnaire was used to collect data on students demographic characteristics and lifestyle behaviors. The Multidimensional Sub health Questionnaire of Adolescents was adopted to assess psychological sub health status. Multivariate binary Logistic stepwise regression analysis was performed to explore the related factors of psychological sub health among secondary vocational school students. Results: The detection rate of psychological sub health among secondary vocational school students was 11.0%, with detection rates of emotional problems, conduct problems, and social adaptation difficulty being 12.3 %, 12.5%, and 9.5%, respectively. Logistic regression analysis revealed that boys and students whose fathers had an educational level of primary school or below, and junior high school, had relatively lower risks of developing psychological sub health or emotional problems, conduct problems, and social adaptation difficulty ( OR =0.55-0.64, all P <0.05). Conversely, students with urban household registration, those with left behind experience, those with poor self rated family economic status, those from other family structures, those classified as overweight and obesity, and those with sleep disorders, frequent consumption of sugar sweetened beverages, frequent consumption of takeout/delivery food, smoking, alcohol consumption, and low to moderate physical activity levels exhibited significantly higher risks across psychological sub health or emotional problems,conduct problems, and social adaptation difficulty ( OR =1.25-4.79, all P <0.05). Conclusions The psychological sub health condition of secondary vocational school students should not be neglected. Psychological sub health of secondary vocational school students is related to multiple factors such as demographic characteristics and lifestyle behaviors. Multi dimensional intervention measures should be implemented to improve their mental health.

[Objective] To explore the predictive value of HALP score for prognosis in patients with multiple myeloma (MM). [Methods] A retrospective analysis was conducted on laboratory indicators and related clinical data of newly diagnosed multiple myeloma (NDMM) patients, treated at the Affiliated Hospital of North Sichuan Medical College from January 2016 to October 2023, prior to their first treatment. The HALP score was calculated, and the optimal cutoff value for HALP was determined using X-tile software. Survival analysis was performed using Kaplan-Meier curves for high HALP and low HALP groups. Univariate and multivariate analyses were conducted using the Cox regression model, and a forest plot was generated using Graphpad Prism to illustrate factors that may impact patient prognosis. The predictive ability of HALP score combined with β2-microglobulin and ECOG score for prognosis in MM patients was evaluated using receiver operating characteristic curve (ROC) analysis. [Results] A total of 203 MM patients were included, with the optimal cutoff value for HALP score being 29.15 (P<0.05). Among them, 101 patients were in the low HALP score group, and 102 patients were in the high HALP score group. The results of univariate and multivariate analysis using the Cox regression model showed that a HALP score <29.15 was an independent risk factor for progression-free survival (PFS) and overall survival (OS) (P<0.05). ROC curve analysis indicated that the combination of HALP score with β2-microglobulin and ECOG score had a higher predictive value for prognosis in MM patients compared to using HALP score alone. [Conclusion] The HALP score is closely related to the prognosis of patients with NDMM. A low HALP score indicates a poorer prognosis, while the combination of HALP score with β2-microglobulin and ECOG score provides a higher predictive value when assessed together.

Objective:To analyze the extraction, chemical composition, antioxidant, and anti-inflammatory activity of the TCM formula essential oil for the treatment of upper respiratory tract infections (URTI); To provide a scientific basis for its further development.Methods:The formula essential oil was extracted using the steam distillation method and analyzed for chemical composition by gas chromatography-mass spectrometry (GC-MS). The DPPH, ABTS scavenging ability, and hydroxyl radical scavenging ability of volatile oils were measured. The effect of the essential oil on the viability of RAW264.7 cells was assessed using the CCK-8 assay. ELISA and Western blot methods were used to determine the effects of volatile oil on LPS induced inflammatory cytokines IL-6 and TNF-α.Results:The average extraction rate of the formula essential oil was 1.12%, with a density of 0.973 2 g/ml. Twelve main chemical components were identified, with 1,8-cineole (42.9%) and patchoulol (19.9%) being the predominant constituents. The essential oil exhibited DPPH and ABTS radical scavenging capacities of 52% and 59%, respectively, and a hydroxyl radical scavenging capacity exceeding 70%. Essential oil could reduce the levels of IL-6 and TNF-α ( P<0.05). Conclusion:TCM formula essential oil for the treatment of URTI contains multiple bioactive components and demonstrates significant antioxidant and anti-inflammatory effects.

Objective::To analyze fetal renal abnormality genetic features and the prenatal characteristics of the 17q12 microdeletion syndrome.Methods::This prospective cohort study examined prenatal ultrasound findings of renal abnormalities in pregnant women who underwent single nucleotide polymorphism (SNP) array or copy number variation sequencing (CNV-seq) testing on amniotic fluid or fetal tissue at Tianjin Central Obstetrics and Gynecology Hospital between January 2016 and August 2022. The study cohort comprised women with advanced maternal age, fetal ultrasound anomalies, high-risk non-invasive prenatal testing results, or suspected 17q12 microdeletion syndrome. Comprehensive clinical data, including maternal age, detailed ultrasound findings, and pregnancy outcomes, were systematically collected. SNP-array analysis was conducted using an Affymetrix CytoScan 750 K Array Chip to identify CNVs and loss of heterozygosity, while CNV-seq was performed on the Illumina HiSeq 2000 platform. Detected variants were classified according to the American College of Medical Genetics and Genomics guidelines. Statistical analyses were performed using SPSS version 27.0.Results::Abnormal renal development was identified in 141 patients, among whom 26 exhibited hyperechogenic kidneys (HCK). Of these, 12 cases were associated with 17q12 microdeletion syndrome, while the remaining 14 were linked to other chromosomal abnormalities. When excluding patients with HCK, those diagnosed with polycystic kidney disease demonstrated a higher prevalence of chromosomal abnormalities compared to those with multicystic dysplastic kidney and renal dysplasia. Although isolated conditions such as horseshoe kidney, hydronephrosis, ectopic kidney, and unilateral kidney typically presented with normal chromosomal findings, the incidence of chromosomal abnormalities increased when these conditions coexisted with other anomalies. A detailed analysis of the correlation between 17q12 microdeletion syndrome and HCK revealed that 12 out of the 14 patients diagnosed with 17q12 microdeletion syndrome exhibited HCK. Genetic testing confirmed the syndrome in seven patients, with five cases attributed to novel mutations and two cases resulting from inherited mutations.Conclusion::Fetal HCK was closely associated with the 17q12 microdeletion syndrome, and polycystic kidney disease showed a higher rate of chromosomal abnormalities. Chromosome test results were mostly normal in patients with other renal abnormalities, such as kidney dysplasia, horseshoe kidneys, hydronephrosis, kidney deficiency, and ectopic kidneys. Prenatal diagnosis is recommended, especially in cases of non-isolated fetal renal abnormalities. This study provides strong evidence supporting a link between fetal renal abnormalities and genetic syndromes.

Objective To establish a method for inducing mouse bone marrow monocytes differentiating into Kupffer cells in vitro,for the study of Kupffer cells.Methods Monocytes were separated from mouse bone marrow and induced by transforming growth factor 1(TGF-β1),macrophage colony-stimulating factor(M-CSF)and delta-like protein 4(DLL4).Induced monocyte-derived Kupffer cells(iMoKCs)were identified by real-time fluorescent quantitative polymerase chain reaction(qPCR),immunofluorescence staining and flow cytometry.Immunofluorescence staining and flow cytometry were used to evaluate the phagocytic capacity of iMoKCs.Cell counting kit-8(CCK-8)was used to evaluate the proliferation capacity.Results Bone marrow monocytes were isolated,after 24 h combined induction,iMoKCs express C-type lectin domain family 4,member f(CLEC4F),C-type lectin domain family 1,member b(CLEC1B)and V-set and immunoglobulin domain containing 4(VSIG4)at mRNA level,and protein CLEC4F.Phagocytic function of iMoKCs were detected by flow cytometry,and nearly 80% of total iMoKCs show bioparticle acceptance.The number of iMoKCs were detected by CCK-8,the counts were 1.4,2.0 and 2.9 times of the initial number(0 h)at 24,48 and 72 h.Conclusion These cells display the immunophenotype of Kupffer cells and show the ability of phagocytosis and proliferation induction through M-CSF,TGF-β1 and DLL4,which could replace primary Kupffer cells for in vitro research.

Objective:To investigate the clinicopathological features, diagnosis, genetic alterations, and biological behaviors of hamartomatous inverted hyperplastic polyp (HIHP) in the gastrointestinal tract.Methods:The clinical, sonographic, endoscopic and pathologic data of 10 HIHP cases diagnosed at the First Affiliated Hospital of Air Force Medical University, Xi′an, China from January 2013 to March 2024 were collected. Their clinicopathological features and histological morphology were analyzed. The cases were further divided into 3 histologic subtypes. Follow-up information was collected to analyze the relationship between histological subtype and prognosis.Results:There were 5 males and 5 females in this cohort. The age of onset was 45-68 years, with a median age of 60.5 years. The polyp-involved sites included 2 cases in gastric fundus, 6 cases in gastric body, 1 case in gastric antrum, and 1 case in duodenum. Digestive endoscopy showed mucosal protrusion lesions in all cases, except 1 case (case 10) of shallow depression on the surface, with the maximum diameter ranging 0.5-2.5 cm. Endoscopic ultrasonography showed multilocular cystic low-density shadows, with septal enhancement (case 4). The preoperative clinical diagnosis was gastric polyp, ectopic pancreas or gastrointestinal stromal tumor. Two cases showed type 1 morphology (i.e., connected with the mucosa, with clear smooth muscle boundaries). One of them (case 10) had a clear opening to form a vase-like morphology, while the other (case 4) had no obvious opening with the surface mucosa. Three cases showed type 2 morphology (i.e., not connected with the mucosa, with clear smooth muscle boundaries). Five cases showed type 3 morphology (i.e., not connected with the mucosa, without clear smooth muscle boundaries or hyperplastic smooth muscle that separated hyperplastic glands showing lobular configuration). Among them, one case of duodenal lesions (case 9) showed gastric type gland hyperplasia and expansion, including gastric fossa, gastric fundic gland and pyloric gland, with various arrangement and combination, accompanied by smooth muscle hyperplasia. In case 10, there was leiomyomatous proliferation in the stroma. The cases 2 and 4 had atypical glandular structures and cell morphology, but immunohistochemistry showed wild-type expression pattern of p53 and a Ki-67 proliferation index of less than 1%, suggesting that it was reactive atypia secondary to inflammation. The results showed that 3 cases had different gene mutations, and no recurrent gene change was identified. All patients survived without disease during the follow-up period of 1-130 months.Conclusions:HIHP is a benign lesion and has no consistently detectable genetic alterations. The histological characteristics of gastrointestinal polyps are complex. Especially, the types 1 and 3 of HIHP have unique gross and microscopic features, which require combination of proper endoscopic sampling and histological examination to correctly classify them.

Objective To investigate the diagnostic and therapeutic value of single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis therapy in the treatment of acute uncomplicated appendicitis.Methods A retrospective analysis was conducted on the clinical data of 39 patients with acute uncomplicated appendicitis who underwent single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis treatment at the Endoscopy center of the hospital from September 2022 to September 2024.Observe the endoscopic manifestations,the rate of maternal and child basket stone removal,the rate of appendiceal stent implantation,the technical success rate,the clinical success rate,the operation time,the hospital stay,the incidence of complications,the visual analogue scale(VAS)score 6 hours after the operation,and the inflammatory indicators 24 hours after the operation.Results In 28 cases(71.8%),congestion and edema could be seen at the opening of the appendix under colonoscopy.In 10 cases(25.6%),pus could be seen flowing out of the opening of the appendix under colonoscopy.In 32 cases(82.1%),a large amount of pus could be seen in the lumen of the appendix under subscopy.In 20 cases(51.3%),appendiceal fecalith could be seen in the lumen of the appendix under subscopy.The technical success rate of single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis treatment was 100.0%(39/39).The operation time was(21.08±7.49)min;Hospital stay:(3.97±2.08)days;Eight cases(20.5%)of patients underwent endoscopic maternal basket stone removal.Appendiceal stent implantation was performed in 14 cases(35.9%)of patients.The clinical success rate is 97.4%(38/39).One patient's clinical symptoms and inflammatory indicators did not improve after the operation,and was transferred to the surgery department for appendectomy.The VAS score of 38 patients was less than 3 points 6 hours after the operation,and the abdominal pain symptoms were significantly relieved.The white blood cell count and the percentage of neutrophils 24 hours after the operation decreased significantly compared with those before the operation,and the differences were statistically significant(P<0.05).None of the 39 patients had complications.The postoperative follow-up was(5.94±4.03)months,and recurrence occurred in 3 cases(7.7%).Conclusion single-use mother-baby choledocoscope-assisted endoscopic retrograde appendicitis therapy is safe and effective in the diagnosis and treatment of acute uncomplicated appendicitis,which is worthy of further promotion and popularization in clinical practice.
