OBJECTIVE: To observe the clinical effect of Tiaoshen Guben holistic therapy of acupuncture and moxibustion (holistic treatment with acupuncture and moxibustion by adjusting the mind and consolidating the root) on comorbidity of depression and insomnia. METHODS: Twenty-four patients with comorbidity of depression and insomnia were included and treated with Tiaoshen Guben holistic therapy of acupuncture and moxibustion. Acupuncture was applied to Baihui (GV20), Guanyuan (CV4), bilateral Neiguan (PC6), etc. The refined moxibustion therapy was delivered at Zhongwan (CV12), Qihai (CV6), bilateral Yongquan (KI1), etc. Subcutaneous embedding therapy with thumb-tack needle was adopted at bilateral Xinshu (BL15), bilateral Pishu (BL20), etc. The intervention was operated once every other day, 3 treatments a week, and for 6 consecutive weeks. Before and after treatment completion, and in 1 month after treatment, Pittsburgh sleep quality index (PSQI) and Hamilton's depression scale (HAMD-17) were adopted to assess sleep quality and depression symptoms in the patients, respectively. Before and after treatment completion, using functional magnetic resonance imaging (fMRI), the functional connectivity (FC) of locus coeruleus (LC) in brain regions was evaluated; and the levels of serum norepinephrine (NE), cortisol (CORT), adrenocorticotropic hormone (ACTH) and corticotropin releasing hormone (CRH) were detected. RESULTS: Compared with the scores before treatment, PSQI and HAMD-17 scores after treatment completion and in 1 month after treatment were reduced (P<0.01); and strengthened FC was revealed between the right LC and the pars opercularis of the left inferior frontal gyrus, as well as the lateral occipital lobe region. After treatment completion, serum NE was elevated (P<0.01), the levels of CORT, ACTH and CRH were reduced (P<0.01). Before and after treatment completion, the difference in FC between the right LC and the pars opercularis of the left inferior frontal gyrus was negatively correlated with the differences in PSQI score (r = -0.484, P = 0.016) and HAMD-17 score (r = -0.233, P = 0.027). CONCLUSION Tiaoshen Guben holistic therapy of acupuncture and moxibustion can effectively alleviate depression symptoms and improve sleep quality in the patients with comorbidity of depression and insomnia, which is obtained probably through reducing the levels of serum CORT, ACTH and CRH, increasing serum NE, strengthening the FC of the right LC with the pars opercularis of the left inferior frontal gyrus and the lateral occipital lobe region.

Early correction of childhood malocclusion is timely managing morphological, structural, and functional abnormalities at different dentomaxillofacial developmental stages. The selection of appropriate imaging examination and comprehensive radiological diagnosis and analysis play an important role in early correction of childhood malocclusion. This expert consensus is a collaborative effort by multidisciplinary experts in dentistry across the nation based on the current clinical evidence, aiming to provide general guidance on appropriate imaging examination selection, comprehensive and accurate imaging assessment for early orthodontic treatment patients.

Objective To investigate the effects of cyclic stretch on migration of MC3T3-E1 cells and its related mechanism. Methods The strain loading system was used to stretch MC3T3-E1 cells cultured in vitro with 15% amplitude, to simulate the mechanical condition in vivo. The wound healing assay was used to detect the migration of MC3T3-E1 cells. Western blotting was used to test Runx2 expression. RNA interfering was used to decrease Runx2 expression. Results Cyclic mechanical stretch with 15% amplitude, 1.25 Hz frequency and lasting for 24 hours could promote the migration of MC3T3-E1 cells and increase the expression level of Runx2. Runx2 interference inhibited the migration of MC3T3-E1 cells in static culture condition. Interference with Runx2 expression in MC3T3-E1 cells could partially reduce the positive effect of cyclic mechanical stretch on cell migration. Conclusions Cyclic stretch can promote the migration of MC3T3-E1 cells, and Runx2 may play an important role in this process. This study provides experimental basis for finding innovative clinical treatment method to promote fracture healing.

Objective To investigate the synergistic effects of pathologically elevated cyclic stretch and platelet-derived microvesicles (PMVs) on migration of vascular smooth muscle cells (VSMCs) and the potential role of calcium in this process. Methods The FX-5000T strain loading system was used to apply cyclic stretch to VSMCs with magnitudes of 5% and 15%, which simulated physiological and hypertensive situation respectively in vitro; wound healing assay was used to analyze VSMCs migration; Ca2+-free medium was used to remove extracellular calcium; 2-APB (an antagonist of IP3R) was used to inhibit the release of intercellular stored calcium; GSK219 (an antagonist of TRPV4) and Nifedipine (an inhibitor of L-type voltage-gated calcium channel) were applied to block the activity of respective calcium channel; thrombin was used to stimulate platelets in vitro which simulated the hypertensive activation of PMVs in vivo. ResultsCompared with 5% cyclic stretch, 15% cyclic stretch significantly promoted VSMC migration. Removal of extracellular calcium inhibited VSMCs migration, but the application of GSK219 and Nifedipine did not affect the migration up-regulated by 15% cyclic stretch; while 2-APB which inhibited the release of intracellular stored calcium could also repress VSMCs migration under 15% cyclic stretch. PMVs further promoted VSMC migration under 15% cyclic stretch condition, and both extracellular calcium and intercellular stored calcium were involved in this process. Conclusions Both intracellular and extracellular calcium play important roles in VSMC migration induced by 15% cyclic stretch, and PMVs synergistically participate in the above process. The study is aimed to provide new mechanobiological insights into the molecular mechanism and clinical targets of vascular remodeling in hypertension.
