ObjectiveTo measure the distance from the surface of Fengfu （GV 16） to the deep important bony structures in children aged 4 to 8 years based on CT three-dimensional reconstruction technology， thereby providing imaging reference data for clinical acupuncture safe operations in terms of different age groups and needle insertion angles. MethodsCervical CT image data were collected from healthy children aged 4 to 8 years with five age groups （4-， 5-， 6-， 7-， 8-year-old groups）， 20 cases in each group. The images were imported into Mimics 21.0 software for three-dimensional reconstruction. The straight-line distances from the skin model surface of the Fengfu （GV 16） to the first underlying bony barrier （such as the lower edge of the occipital bone， the posterior arch of the atlas vertebra） were measured at intervals of 5° on both the transverse section （0° ± 35°） and the sagittal section （40° upward to 40° downward on the diagonal）. The correlation between the measured distance， age， and angle was analyzed. ResultsIn the transverse and sagittal sections， the measured distance from the skin surface to the underlying bone of Fengfu （GV 16） at each angle increased with age. In the transverse section， the increase was relatively small within the 0° to 20° angle range， whereas a more pronounced increase was observed when the angle exceeded 20°； at measurement angles of 30° to 35°， the distance of the skin surface to the bone at Fengfu （GV 16） in the 7- and 8-year-old groups was significantly greater than that in the 4-year-old group （P＜0.05）. In the sagittal section， the measured distance from the skin surface to the bone at Fengfu （GV 16） was shortest and changed greatly at oblique upward angles of 15° to 40° within each age group， and increased markedly at near-vertical angles of 0° to 10°； it was longest at oblique downward angles of -40° to -5° and showed relatively gradual changes. ConclusionThis study obtained the imaging distance data from Fengfu （GV 16） to the surrounding bony structures in children aged 4 to 8 years through three-dimensional modeling， finding that this distance has clear age and angle dependence， which can provide quantitative evidence for developing individualized and precise safe acupuncture schemes at Fengfu （GV 16） in pediatric clinical practice.

Objective:To evaluate the role of necroptosis in paclitaxel-induced cognitive dysfunction in mice.Methods:Thirty SPF healthy male C57BL/6N mice, aged 6-8 weeks, weighing 20-25 g, were divided into 3 groups ( n=10 each) using a random number table method: vehicle control group (Veh group), paclitaxel group (PTX group), and paclitaxel+ a specific inhibitor of necroptosis Necrostatin-1 group (P+ N group). In PTX group and P+ N group, paclitaxel 10 mg/kg (diluted to 5 mg/ml in anhydrous ethanol and castor oil [1∶1], and further diluted to 1 mg/ml in 0.9% normal saline before use) was intraperitoneally injected daily for 7 consecutive days to induce cognitive dysfunction. P+ N group received an intraperitoneal injection of Necrostatin-1 6.5 mg/kg (diluted to 10 mg/ml in dimethyl sulfoxide, and further diluted to 1 mg/ml in 0.9% normal saline before use) at 2 h before paclitaxel administration every other day, 4 times in total. Veh group received the equal volume of solvent at the matched time points as previously described in P+ N group. After establishment of the model, spontaneous locomotor activity was assessed using the open field test, followed by the novel object recognition test and the Morris water maze to evaluate the cognitive function. The animals were sacrificed after the end of the Morris water maze test, and the hippocampal tissues were collected for determination of the expression of necroptosis-related proteins receptor-interacting serine/threonine-protein kinase 1 (RIPK1), RIPK3, mixed lineage kinase domain-like protein (MLKL), and phospho-MLKL (p-MLKL) (by Western blot analysis) and contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) (double immunofluorescence staining) and for observation of the localization of programmed necrosis cells (using enzyme-linked immunosorbent assay). Results:There were no significant differences in the total distance traveled and mean movement speed in the open field test or swimming speed in the Morris water maze test among the three groups ( P>0.05). Compared to Veh group, the time spent in the central zone in the open field and time spent in the original platform quadrant were significantly shortened, the discrimination index was decreased, the escape latency was prolonged, the number of crossing the original platform was reduced, the expression of RIPK1, RIPK3, MLKL and p-MLKL was up-regulated, the contents of TNF-α and IL-1β were increased, and the number of RIPK1-positive neurons was increased in PTX group ( P<0.05). Compared to PTX group, the time spent in the central zone in the open field test and time spent in the original platform quadrant were significantly prolonged, the discrimination index was increased, the escape latency was shortened, the number of crossing the original platform was increased, the expression of RIPK1, RIPK3, MLKL and p-MLKL was down-regulated, the contents of TNF-α and IL-1β were decreased, and the number of RIPK1-positive neurons was decreased in P+ N group ( P<0.05). Conclusions:Necroptosis in hippocampal neurons can lead to neuroinflammation, thus contributeing to paclitaxel-induced cognitive dysfunction in mice.

Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Objective:To explore the relationship between maternal rejection and internet addiction in college students, as well as the chain mediating role of rejection sensitivity and adaptability.Methods:From March to May 2024, a total of 1 119 college students were surveyed using the short-form Egna Minnen av Barndoms Uppforstran for Chinese(s-EMBU-C), internet addiction test(IAT), rejection sensitivity questionnaire(RSQ), and the China college student adjustment scale(CCSAS).SPSS 26.0 statistical software was used for independent sample t-test, one-way ANOVA, Pearson product moment correlation, and multiple linear regression analysis, and PROCESS 4.0 macro program was used for chain mediation analysis. Results:(1)Maternal rejection (11.19±2.97) was positively correlated with internet addiction (44.89±9.74)( r=0.60, P<0.01) and rejection sensitivity (102.93±55.63)( r=0.63, P<0.01), while negatively correlated with adaptability (200.19±14.18)( r=-0.56, P<0.01) among college students. Rejection sensitivity was positively correlated with internet addiction ( r=0.75, P<0.01) and negatively correlated with adaptability ( r=-0.76, P<0.01). Adaptability was negatively correlated with internet addiction ( r=-0.68, P<0.01). (2)Maternal rejection had a significant direct effect on internet addiction among college students (effect value=0.193, 95% CI=0.145-0.241), accounting for 32.06%(0.193/0.602) of the total effect. Rejection sensitivity mediated the relationship between maternal rejection and internet addiction (effect value=0.290, 95% CI=0.232-0.357), accounting for 48.17%(0.290/0.602) of the total effect. Adaptability also mediated this relationship (effect value=0.028, 95% CI=0.009-0.053), accounting for 4.65%(0.028/0.602) of the total effect. Additionally, there was a chain mediation effect of rejection sensitivity and adaptability on the relationship between maternal rejection and internet addiction (effect value=0.091, 95% CI=0.052-0.130), accounting for 15.12%(0.091/0.602) of the total effect. Conclusion:Maternal rejection can directly influence internet addiction in college students, and it can also indirectly influence internet addiction through the independent mediating effects of rejection sensitivity and adaptability, as well as through the chain mediating effects of both rejection sensitivity and adaptability.

Objective:To analyze the comorbidity patterns between thyroid dysfunction and other common cardiometabolic diseases.Methods:In this cross-sectional study, 93 967 participants aged 18 years or older who underwent thyroid function tests at the Health Checkup Center of China-Japan Friendship Hospital between 2017 and 2024 were included. The comorbidity patterns between thyroid dysfunction and six common cardiometabolic diseases of obesity, diabetes, hypertension, dyslipidemia, hyperuricemia, and non-alcoholic fatty liver disease (NAFLD) were described systematicly. The logistic regression models was used to analyze the association between thyroid dysfunction and these cardiometabolic diseases.Results:The detection rates of subclinical hyperthyroidism, overt hyperthyroidism, subclinical hypothyroidism, and overt hypothyroidism in those participants was 1.9%, 0.9%, 3.7% and 1.1%, respectively. The proportion of the paticipants with subclinical hyperthyroidism, overt hyperthyroidism, subclinical hypothyroidism, and overt hypothyroidism who had at least one comorbid cardiometabolic disease was 67.5%, 64.8%, 73.5%, and 77.6%, respectively; the proportion of those participants with two or more concurrent cardiometabolic diseases was 38.6%, 36.7%, 42.8%, and 47.5%, respectively; and the proportion with three or more concurrent cardiometabolic diseases was 19.0%, 18.1%, 22.9%, and 27.5%, respectively. After adjusting for age and gender, the participants with overt hypothyroidism (≥2 comorbidities: OR=1.7, 95% CI: 1.5-1.9;≥3 comorbidities: OR=1.8, 95% CI: 1.5-2.1) or subclinical hypothyroidism (≥2 comorbidities: OR=1.3, 95% CI: 1.2-1.4;≥3 comorbidities: OR=1.3, 95% CI: 1.2-1.4) had a significantly higher risk of multiple cardiometabolic diseases when compared with euthyroid individuals. Analysis of comorbidity patterns revealed that individuals with overt hyperthyroidism ( OR=1.8, 95% CI: 1.0-3.1) and subclinical hyperthyroidism ( OR=1.5, 95% CI=1.0-2.2) had a significantly higher risk of the “NAFLD+hypertension” comorbidity complex when compared with euthyroid individuals. Similarly, individuals with overt hypothyroidism ( OR=1.7, 95% CI: 1.2-2.3) and subclinical hypothyroidism ( OR=1.3, 95% CI: 1.1-1.5) had a significantly higher risk of the “dyslipidemia+NAFLD+hyperuricemia” comorbidity complex when compared with euthyroid individuals. Conclusion:Individuals with thyroid dysfunction exhibit a high prevalence of comorbid cardiometabolic diseases, highlighting the need for future research on integrated management strategies for multimorbidity in this population.
