Asian Spine Journal 2025;19(1):64-73
Methods:
This study enrolled 40 patients with AIS, 20 patients with congenital scoliosis (CS), and 20 patients with spinal degenerative disease (SDD). All patients underwent open posterior surgery in our hospital, and a paravertebral muscle (multifidus muscle) biopsy was performed intraoperatively. This study included many indexes that describe muscle, especially dystrophin staining. The above pathological results were compared among the AIS, CS, and SDD groups. The correlation between the Cobb angle and Nash–Moe classification and the above pathological results was analyzed in patients with AIS.
Results:
Significant reductions in the dystrophin staining of dystrophin-1 (p<0.001), dystrophin-2 (p<0.001), and dystrophin-3 (p<0.001) were observed in the AIS group than in the CS and SDD groups. The higher the Nash–Moe classification in the AIS group, the more significant the loss of dystrophin-2 (p=0.042) in the convex paraspinal muscles. Additionally, a significantly positive correlation was observed between the reductions of dystrophin-2 on the concave side of the AIS group and Cobb angle (p=0.011).
Conclusions
Dystrophin protein deficiency in the paraspinal muscles plays a crucial role in AIS formation and progression. The severity of scoliosis in patients with AIS is correlated with the extent of dystrophin loss in the paravertebral muscles. Therefore, dystrophin dysfunction may be relevant to AIS occurrence and development.

Early identification of adolescent depression requires objective biomarkers. This study investigated the functional near-infrared spectroscopy (fNIRS) activation patterns and mismatch negativity (MMN) characteristics in adolescents with first-episode mild-to-moderate depression. We enrolled 33 patients and 33 matched healthy controls, measuring oxyhemoglobin (Oxy-Hb) concentration in the frontal cortex during verbal fluency tasks via fNIRS, and recording MMN latency/amplitude at Fz/Cz electrodes using event-related potentials (ERP). Compared with healthy controls, the depression group showed significantly prolonged MMN latency [Fz: (227.88 ± 31.08) ms vs. (208.70 ± 25.35) ms, P < 0.01; Cz: (223.73 ± 29.03) ms vs. (204.18 ± 22.43) ms, P < 0.01], and obviously reduced Fz amplitude [(2.42 ± 2.18) μV vs. (5.65 ± 5.59) μV, P = 0.03]. A significant positive correlation was observed between MMN latencies at Fz and Cz electrodes ( P < 0.01). Oxy-Hb in left frontopolar prefrontal channels (CH15/17) was significantly decreased in patient group ( P < 0.05). Our findings suggest that adolescents with depression exhibit hypofunction in the left prefrontal cortex and impaired automatic sensory processing. The combined application of fNIRS and ERP techniques may provide an objective basis for early clinical identification.

The accurate and timely detection of biochemical coagulation indicators is pivotal in pulmonary and critical care medicine. Despite their reliability, traditional laboratories often lag in terms of rapid diagnosis. Point-of-care testing (POCT) has emerged as a promising alternative, which is awaiting rigorous validation. We assessed 226 samples from patients at the First Affiliated Hospital of Guangzhou Medical University using a Beckman Coulter AU5821 and a PUSHKANG POCT Biochemistry Analyzer MS100. Furthermore, 350 samples were evaluated with a Stago coagulation analyzer STAR MAX and a PUSHKANG POCT Coagulation Analyzer MC100. Metrics included thirteen biochemical indexes, such as albumin, and five coagulation indices, such as prothrombin time. Comparisons were drawn against the PUSHKANG POCT analyzer. Bland-Altman plots (MS100: 0.8206‒0.9995; MC100: 0.8318‒0.9911) evinced significant consistency between methodologies. Spearman correlation pinpointed a potent linear association between conventional devices and the PUSHKANG POCT analyzer, further underscored by a robust correlation coefficient (MS100: 0.713‒0.949; MC100: 0.593‒0.950). The PUSHKANG POCT was validated as a dependable tool for serum and whole blood biochemical and coagulation diagnostics. This emphasizes its prospective clinical efficacy, offering clinicians a swift diagnostic tool and heralding a new era of enhanced patient care outcomes.

Objective:To describe the prevalence of food allergy among children aged 0-5 years in China and to explore related influencing factors.Methods:Multistage stratified random sampling method was used to collect data from 275 surveillance sites of the China National Nutrition and Health Survey of Chinese children and lactating mothers programs in 31 provinces (autonomous regions and municipalities) of China in 2016-2017. A total of 70 107 participants aged 0-5 years were included in this study. The study collected information of participants' demographic characteristics and food allergies by face-to-face questionnaire. The prevalence of food allergy was analyzed, using the complex data weighting method. The logistic regression models were used to analyze the influencing factors related to food allergy.Results:The overall prevalence of self-reported food allergy among children aged 0-5 years was 4.81%. Prevalence rates in infants aged 0-5 months, and 6-23 months and preschool children aged 2-5 years were 0.81%, 4.68% and 5.26%, respectively. The results of logistic analysis showed that there was a significantly positive correlation between factors including children from 6 months to 5 years old, urban area, southwest area, first-born, mothers with college education or above, and the prevalence of food allergy in children. Shrimp, poultry eggs, crab shellfish, fruit, milk and fish appeared the common allergic foods in children aged 0-5 years, with prevalence rates of self-reported food allergy as 1.55%, 1.25%, 0.99%, 0.97%, 0.87% and 0.86%, respectively. The proportion of single food allergy in children with allergies was 69.85%.Conclusions:Among children aged 0-5 years, the prevalence of self-reported food allergy increases with age, in China. Foods that is prone to allergies include fish, shrimp, crab, shellfish, poultry eggs, milk and fruits, etc. Most allergies were only caused by single food in children, under observation.

Objective To investigate the role of SIRT1/autophagy pathway in mediating the regulatory effect of lncRNA SOX2OT on 5-fluorouracil(5-FU)resistance in cholangiocarcinoma cells.Methods HCCC-9810 cells were used to construct a 5-FU-resistant cell model(HCCC-9810/5-FU cells),and the expression levels of lncRNA SOX2OT and SIRT1 mRNA and the protein expressions of SIRT1,Beclin1,LC3 and P62 were detected with qRT-PCR and Western blotting.The effects of transfection with a SOX2OT mimic on drug resistance and cell migration of HCCC-9810/5-FU cells were detected using CCK-8 assay and wound healing assay,and the changes in expressions of SOX2OT,SIRT1,Beclin1,LC3 and P62 were detected.Rescue experiment was performed by co-transfection of HCCC-9810/5-FU cells with both a SOX2OT-overexpressing plasmid and si-SIRT1 to confirm the role of SIRT1 in SOX2OT-mediated regulation of 5-FU resistance.A RNA pulldown assay was used to verify the targeted binding between SOX2OT and SIRT1.Results The proliferation of HCCC-9810 cells was significantly inhibited after treatment with different concentrations of 5-FU(P<0.05).The 5-FU-resistant cells showed significantly increased protein expressions of SIRT1,Beclin1 and p62,an increased LC3Ⅱ/LC3Ⅰ ratio,and enhanced expressions of SIRT1 mRNA and SOX2OT(P<0.05).Transfection of the resistant cells with SOX2OT mimic significantly enhanced cell migration and increased the protein expressions of SIRT1,Beclin1 and p62,the LC3Ⅱ/LC3Ⅰratio,and expression levels of SIRT1 mRNA and SOX2OT(P<0.05),and these changes were obviously attenuated by SIRT1 knockdown,which also resulted in lowered 5-FU resistance of the cells without significantly affecting the expression level of SOX2OT(P>0.05).RNA pulldown assay suggested that SOX2OT could directly bind to SIRT1.Conclusion LncRNA SOX2OT enhances 5-FU resistance in HCCC-9810 cells by promoting autophagy through up-regulating SIRT1 expression.

Objective:To investigate the impact of rosacea on patients' quality of life and mental health, and to analyze variations across different subtypes, gender, sun exposure, smoking status, ethnicity, and educational levels, as well as patients' demands for treatment.Methods:It was a cross-sectional study from October 2022 to January 2024, 177 rosacea patients from the Department of Dermatology, the First Affiliated Hospital of Kunming Medical University were surveyed. The cohort comprised 36 males and 141 females, with a median age of 35 (29, 44) years. Data collected through questionnaires included general information, Dermatology Life Quality Index (DLQI), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Patient Need Questionnaire (PNQ). Statistical analysis was conducted on the collected data.Results:The median DLQI score was 10 (3, 15), indicating moderate impact. The median GAD-7 score was 5 (2, 7), suggesting mild anxiety; while the median PHQ-9 score was 6 (2, 9), indicating mild depression. Female patients scored higher in both DLQI and GAD-7 than males ( P<0.05). Papulopustular subtypes had higher DLQI and GAD-7 scores compared to other subtypes ( P<0.01). Patients with lower education levels scored higher in DLQI and GAD-7 than those with higher education ( P<0.01), and non-smokers had higher GAD-7 scores than smokers ( P<0.05). Significant positive correlations were found between DLQI and PHQ-9 ( r=0.39, P<0.01), and DLQI and GAD-7 ( r=0.51, P<0.01), as well as between PHQ-9 and GAD-7 ( r=0.59, P<0.01). Regarding treatment needs, 159 patients (89.8%) expressed a strong desire for a clear diagnosis and treatment plan, and the same number wished for a complete resolution of all skin lesions. Female patients consistently demonstrated significantly stronger demands in all 28 treatment need items (all P<0.05). Conclusions:Rosacea significantly affects patients' quality of life and mental health, particularly among females, individuals with papulopustular subtypes, and those with lower education levels. There is a strong demand for definitive diagnostic and therapeutic plans, especially among female patients.

Objective:To explore the skin conditions, skin diseases, and physiological functions of the facial skin in plateau children.Methods:It was a cross-sectional study. A total of 327 children aged 6-12 years which included 164 males (9.97±2.56 years) and 163 females (10.23±2.05 years) were recruited in this study from six different altitude groups from June 2022 to February 2024 at the Department of Dermatology, the First Affiliated Hospital of Kunming Medical University: Yongren group, Kunming group, Meigu group, Dashanbao group, Lashihai group, and Rikaze group at altitudes of 1 500, 1 800, 2 000, 3 100, 3 500, and 3 800 m. and 76, 63, 21, 34, 64, and 69 children were recruited from each group, respectively. The facial skin characteristics and the transepidermal water loss, stratum corneum hydration, the L * value, and the a * value, which were tested by non-invasive instruments, were collected. Subsequently, meteorological data for the six locations were obtained from CNKI and China Meteorological Data Service Centre, including monthly temperature, monthly humidity, and annual sunshine duration. Finally, all data were analyzed using SPSS 29.0. Results:The top five facial skin diseases in 327 children were telangiectasia (249, 82.57%), freckles (173, 52.91%), nevus (125, 38.23%), pityriasis alba (98, 29.97%), and scars (93, 28.44%). In addition, a total of 15 cases of melasma with a lower score of mMASI were identified in this study. In all the subjects, 7.65% had severe desquamation, 19.57% had moderate desquamation, and 40.98% had mild desquamation. The whole transepidermal water loss value of highland children's face was (6.55±3.95) g·m -2·h -1, the stratum corneum hydration value was (24.19±19.45) au, the L * value was (51.76±4.31) au, the a * value was (15.60±2.29) au. The Dashanbao group was higher than the other 5 groups ( F=18.76, P<0.05), and the stratum corneum hydration of the Lashihai and Rikaze groups was higher than any other groups ( F=157.292, P<0.05), the L * value of the Meigu group was the lowest in any other 5 groups ( F=14.06, P<0.05), the a * value of the Kunming group was lower than other all groups ( F=11.88, P<0.05). Conclusions:The proportion of facial skin diseases varies slightly across altitudes, with significant differences in skin barrier function among the six groups of children with impaired skin barrier function in the highlands.
