Objective To investigate the risk of permanent hair dye use for connective tissue disease ( CTD ) with positive antinuclear antibodies ( ANA ).Methods We conducted a population-based case-control study to analyze 440 CTD patients from the department of our hospital.Four hundreds and forty patients' relatives or friends who were free from any CTD were selected as controls.Patients and controls were matched in sex and age.A face-to-face interview was adopted to finish questionnaires about subjects' demographic data and the use of permanent hair dye.Data about the duration,frequency,times of usage and allergy related to hair dye were collected.Medical history was also reviewed,such as the diagnosis,disease course,primary symptoms,serum tests and organ involvements.Statistical analysis was performed by SPSS 17.0 software using x2 test and Logistic regression.Results The association between the use of permanent hair dye and CTD did not reach statistical significance (OR=1.282,95％CI 0.966-1.700,P=0.085 ),when the relationship of hair dye use with systemic lupus erythematosus (SLE) was tested,the same result (OR=1.092,95％CI 0.795-1.500,P=0.587 ) could be revealed.Conclusion This preliminary study has shown that the use of permanent hair dye couldn't induce the occurrence of CTD.

Objective: To explore the trend of blood pressure among children and adolescents and its correlation with pubertal development and nutritional status, so as to provide a scientific basis for developing prevention strategies targeting early stage hypertension. Methods: In September 2023, a multi stage random cluster sampling was used to select 20 241 primary and secondary school students aged 7-18 years from 57 schools in Jinzhong, whose height, weight, and blood pressure were measured. The Chi square test for trend was used to analyze the change trend in the detection rate of elevated blood pressure and hypertension in children and adolescents with the development of adolescence puberty, and the Logistic regression was used to analyze the correlation between elevated blood pressure and hypertension and nutritional status. Results: The prevalence of elevated blood pressure was 17.3% among children and adolescents. The middle and late pubertal groups had the highest prevalence (23.2% and 24.3%), followed by the early pubertal group (19.5%) and the prepuberty group (10.8%) ( χ 2 trend =372.86， P <0.01). The prevalence of hypertension was 14.8%, with the highest prevalence reported in the late pubertal group (22.4%), followed by the middle pubertal group (18.9%), and the early pubertal (13.0%)/prepuberty (12.2%) groups ( χ 2 trend =175.43， P <0.01). The prevalence of elevated blood pressure and hypertension increased with pubertal development, regardless of gender, region, or nutritional status ( χ 2 trend =9.21-771.90, P <0.01). Overweight and obesity were influencing factors of elevated blood pressure and hypertension among children and adolescents during all stages of pubertal development ( OR =1.2-2.8， P <0.01). Conclusion The prevalence of elevated blood pressure and hypertension among children and adolescents during pubertal development is high, showing an increasing trend with pubertal development.

This study was carried out to defect the effects of acupuncture and moxibustion therapy on the proliferation and differentiation of neural stem cells in the olfactory bulb of senescence-accelerated mouse P8. Immunofluorescence double staining methods(BrdU/Nestin, BrdU/MAP-2 and BrdU/beta-tubulin III) were used. The results show that both acupuncture and moxibustion could improve proliferation of neural stem cells, but only moxibustion could induce differentiation of neural stem cells into neuron.

Objective To explore the effects of different acupoints,different target organs,and different interventions on acupoint efficacy based on ACU&MOX-DATA platform;To illustrate and visualize whether the above factors have the characteristics of"specific effect"or"common effect"of acupoint efficacy.Methods The multi-source heterogeneous data were integrated from the original omics data and public omics data.After standardization,differential gene analysis,disease pathology network analysis,and enrichment analysis were performed using Batch Search and Stimulation Mode modules in ACU&MOX-DATA platform under the conditions of different acupoints,different target organs,and different interventions.Results Under the same disease state and the same intervention,there were differences in effects among different acupoints;under the same disease state,the same acupoint and intervention,the responses produced by different target organs were not completely consistent;under the same disease state and acupoint,there were differences in effects among different intervention measures.Conclusion Based on the analysis of ACU&MOX-DATA platform,it is preliminary clear that acupoints,target organs,and interventions are the key factors affecting acupoint efficacy.Meanwhile,the above results have indicated that there are specific or common regulatory characteristics of acupoint efficacy.Applying ACU&MOX-DATA platform to analyze and visualize the critical scientific problems in the field of acupuncture and moxibustion can provide references for deepening acupoint cognition,guiding clinical acupoint selection,and improving clinical efficacy.

Marsdenia tenacissima injection, a standard Marsdenia tenacissima extract (MTE), has been approved as an adjuvant therapeutic agent for various cancers. Our previous study showed that MTE inhibited the proliferation and metastasis of prostate cancer (PCa) cells. However, the underlying mechanisms and active ingredients of MTE against PCa were not completely understood. This study revealed that MTE induced significant decreases in cell viability and clonal growth in PCa cells. In addition, MTE induced the apoptosis of DU145 cells by reducing the mitochondrial membrane potential and increasing the expression of Cleaved Caspase 3/7, Cyt c, and Bax. In vivo, DU145 xenografted NOD-SCID mice treated with MTE showed significantly decreased tumor size. TUNEL staining and Western blot confirmed the pro-apoptotic effects of MTE. Network pharmacology analysis collected 196 ingredients of MTE linked to 655 potential targets, and 709 PCa-associated targets were retrieved, from which 149 overlapped targets were screened out. Pathway enrichment analysis showed that the HIF-1, PI3K-AKT, and ErbB signaling pathways were closely related to tumor apoptosis. Western blot results confirmed that MTE increased the expression of p-AKT^Ser473 and p-GSK3β^Ser9, and decreased the expression of p-STAT3^Tyr705in vitro and in vivo. A total of 13 compounds in MTE were identified by HPLC-CAD-QTOF-MS/MS and UPLC-QTOF-MS/MS. Molecular docking analysis indicated that six compounds may interact with AKT, GSK3β, and STAT3. In conclusion, MTE induces the endogenous mitochondrial apoptosis of PCa by regulating the AKT/GSK3β/STAT3 signaling axis, resulting in inhibition of PCa growth in vitro and in vivo.
