Two non-destructive instrumental methods, infrared spectroscopy (IR) and X-ray diffraction (XRD), were studied for quality evaluation of Lobelia chinensis Lour. (L. chinensis). We obtained the IR spectra and XRD patterns of L. chinensis collected from different sources. The similarity of samples was analyzed by cal-culating the cosine coefficient. The cosine values were in the range of 0.83–0.90, indicating that the main components of L. chinensis samples are similar. Sample L1 and L6 showed a slightly lower similarity than that of L2, L3, L4, L5 detected by the two methods, which revealed that IR and XRD methods exhibited analogous detection ability for quality evaluation of L. chinensis. The two methods could be highly re-commended as simple and rapid detection means for quality evaluation of L. chinensis.

Accurate segmentation of oral surgery-related tissues from cone beam computed tomography(CBCT)images can significantly accelerate treatment planning and improve surgical accuracy.In this paper,we propose a fully automated tissue segmentation system for dental implant surgery.Specifically,we propose an image preprocessing method based on data distribution histograms,which can adaptively process CBCT images with different parameters.Based on this,we use the bone segmentation network to obtain the segmentation results of alveolar bone,teeth,and maxillary sinus.We use the tooth and mandibular regions as the ROI regions of tooth segmentation and mandibular nerve tube segmentation to achieve the corresponding tasks.The tooth segmentation results can obtain the order information of the dentition.The corresponding experimental results show that our method can achieve higher segmentation accuracy and efficiency compared to existing methods.Its average Dice scores on the tooth,alveolar bone,maxillary sinus,and mandibular canal segmentation tasks were 96.5%,95.4%,93.6%,and 94.8%,respectively.These results demonstrate that it can accelerate the development of digital dentistry.

Anaplastic thyroid carcinoma(ATC)is the most aggressive malignancy with poor prognosis.The pathogenesis of ATC is complex,and there is no effective treatment at present.In recent years,with the deep understanding of the genetic(such as BRAF V600E,TP53,TERT,PIK3CA mutations,etc.)and epigenetic(such as histone methylation,histone deacetylation,microRNA regulatory pathways,etc.)changes driving ATC,molecular targeted therapy has brought new hope to ATC patients.This article reviews the molecular mechanisms of ATC and the latest achievements in targeted therapy and other therapies.

Objective:To investigate the value of brainstem auditory evoked potential (BAEPs) combined with cochlear electrogram (ECochG) monitoring in the protection of auditory function during microvascular decompression (MVD) for patients with facial spasm (HFS).Methods:Clinical data of 908 patients with HFS who received MVD treatment in our hospital from January 2018 to December 2020 were retrospectively analyzed. The patients were divided into BAEPs group ( n=309), ECochG group ( n=301) and BAEPs+ECochG group ( n=298) according to the different methods of auditory nerve function monitoring. Waveform extraction rate, mean extraction time, amplitude, latency, intraoperative warning effect of 3 monitoring methods, as well as hearing status immediately after surgery and during follow-up were compared in patents from the 3 groups. Results:(1) The overall waveform extraction rate in ECochG group and BAEPs+ECochG group was significantly higher than that in BAEPs group, and the average waveform extraction time in ECochG group and BAEPs+ECochG group was significantly shorter than that in BAEPs group ( P<0.05). The amplitude of compound action potential (CAP) wave in ECochG group was significantly higher than that of V wave in BAEPs group, and the latency of CAP wave was also significantly earlier than that of V wave ( P< 0.05). (2) A total of 48 patients of the 288 patients in the BAEPs group showed warning signs; a total of 73 of the 292 patients in the ECochG group showed warning signs; and a total of 65 of the 292 patients in the BAEPs+ECochG group showed warning signs. (3) There was significant difference in hearing grading (American Association of Otolaryngology Head and Neck Surgery [AAO-HNS] grading) among the 3 groups immediately after surgery ( H=18.041, P=0.000), and the average rank suggested that the hearing of patients in the BAEPs+ECochG group was superior to the other two groups. All patients were followed up for an average of 15 months (ranged 3-24 months); there was still a significant difference in AAO-HNS grading among the 3 groups ( H=29.625, P=0.000), and the hearing of patients in the BAEPs+ECochG group was still superior to the other two groups. Conclusion:The combined application of ECochG and BAEPs monitoring can reflect the changes of intraoperative hearing impairment comprehensively, accurately and timely, which is of great significance for the protection of auditory function in HFS patients during MVD.
