Application Development of Baihui (GV20) Moxibustion in Ancient China: a Data Analysis Study Based on Ancient Books.

Importance: We compile and analyze ancient literature related to Baihui (GV20) moxibustion and summarize the development of its ancient clinical application. Observations: The Chinese Medical Classic (5th edition) was used as the search source to screen and organize articles related to Baihui moxibustion to establish a database. We created indexing norms according to study characteristics and indexed books, dynasties, literary styles, disease key words, matching acupoints, combinations, moxibustion amounts, and moxa cone sizes. SPSS version 24.0 software was used to calculate the index results. A total of 320 articles that met the requirements were finally included and were attributed to 99 ancient books, spanning from the Western Han Dynasty to the Qing Dynasty. A total of 45 keywords were used for disease evidence: the most frequent occurrences were internal medicine (primary category), limb meridians (secondary category), and head diseases (specific patterns). Conclusions and Relevance: Baihui moxibustion has been updated and developed in the literature over the ages, and the method of Baihui moxibustion is diverse. The main treatment rule of Baihui moxibustion considers the whole body and close treatment of partial diseases. Baihui moxibustion also has the rule of following meridian indications, with treatment based on syndrome differentiation and compatible application. Baihui moxibustion alone has a relatively strong effect of raising yang and lifting the sunken, which can treat the sinking of qi and deficiency.

Evaluation of ciliary body morphology and position of the implantable collamer lens in low-vault eyes using ultrasound biomicroscopy.

PURPOSE: To investigate the ciliary body anatomy and position of the implantable collamer lens (ICL) in low-vault eyes and analyze factors related to insufficient vault. SETTING: Zhongshan Ophthalmic Center, Guangzhou, China. DESIGN: Retrospective case-control observational study. METHODS: In this study, 73 eyes of 73 patients with an insufficient vault (<250 µm) were matched with 73 eyes with an ideal vault (250 to 750 µm). Ultrasound biomicroscopy was used to determine the ciliary body morphology and ICL position. The biometric parameters acquired by Scheimpflug tomography were compared. The correlation between the vault and these factors was analyzed, and the least absolute shrinkage and selection operator method was used to screen the risk factors for low vault. RESULTS: The low-vault group had a steeper corneal curvature, thicker lens thickness (LT), higher crystalline lens rise, and shorter axial length (AL) (all P < .005). The ciliary process length (CPL) and maximum ciliary body thickness (CBTmax) were significantly smaller, and the trabecular-ciliary angle (TCA), iris-ciliary angle (ICA), and ciliary sulcus width (CSW) were significantly greater in the low-vault eyes (all P < .005). The low-vault group had more ICL haptics below the ciliary process, and TCA, ICA, CPL, CBTmax, CSW, and haptic position were related to the postoperative vault (all P < .05). CPL, AL, and LT were identified as predictors of a low vault. CONCLUSIONS: Malposition of ICL haptics behind the ciliary process is a risk factor for low vault. A shorter CPL, thicker LT, and shorter AL are significant risk factors for the postoperative low vault.

[Vital pulp therapy of damaged dental pulp].

The development of an expert consensus on vital pulp therapy can provide practical guidance for the improvement of pulp damage care in China. Dental pulp disease is a major type of illness that adversely affects human oral health. Pulp capping and pulpotomy are currently the main methods for vital pulp therapy. Along with the development of minimal invasion cosmetic dentistry, using different treatment technologies and materials reasonably, preserving healthy tooth tissue, and extending tooth save time have become urgent problems that call for immediate solution in dental clinics. This paper summarizes the experiences and knowledge of endodontic experts. We develop a clinical path of vital pulp therapy for clinical work by utilizing the nature, approach, and degree of pulp damage as references, defense and self-repairing ability of pulp as guidance, and modern technologies of diagnosis and treatment as means.
