Chinese herbal medicine compound of flavonoids adjunctive treatment for oral cancer

Oral cancer is a prevalent global issue, with oral squamous cell carcinoma constituting the majority of cases. Standard treatments like surgery, radiotherapy, and chemotherapy are available but may have adverse effects. Molecular gene therapy, focusing on genetic mutations linked to oral cancer, presents a promising alternative.In this study, we evaluated 27 chemotherapeutic drugs and 63 Chinese herbal medicines for their effectiveness, categorized them by their cellular mechanisms, and identified potential adjuvant therapy candidates for oral cancer. Our findings highlight the impact of natural flavonoids on oral cancer cells, inducing apoptosis, and confirming their potential in molecular genetic analysis. In conclusion, the natural compounds present in Chinese herbal medicine, particularly flavonoids, offer a promising avenue to target specific genetic mutations in oral cancer cells. This approach may reduce the risks associated with oral cancer treatment and pave the way for innovative adjuvant therapies.

Role of Nutrients on Platelets Participation in Leukocyte Recruitment and Inflammation Resolution in Inflammatory Diseases, Including Covid-19

Interactions of platelets with circulating cells and vessel walls are implicated in various inflammatory processes. In certain circumstances, the hemostatic and inflammatory functions of platelets may overlap. Platelet–lymphocyte/leukocyte interactions can effectively regulate chronic inflammatory conditions. Platelet extracellular vesicles play a prominent role in thrombosis. In this review, we provide an overview of the molecules associated with platelet–cell interaction and the role of platelet extracellular vesicles in cardiovascular disorders and coronavirus disease 2019, which has posed a significant threat to global health due to infection with severe acute respiratory syndrome coronavirus 2. In addition to recruiting leukocytes to resolve inflammation associated with inflammatory diseases, such as coronavirus disease 2019, nutrients may also play a significant role in human metabolism.

A method for assessing the regional vibratory pattern of vocal folds by analysing the video recording of stroboscopy

Stroboscopy and kymography have been used to examine the motional abnormality of vocal folds and to visualise their regional vibratory pattern. In a previous study (Laryngoscope, 1999), we introduced the conceptual idea of videostrobokymography, in which we applied the concept of kymography on the pre-recorded video images using stroboscopy, and showed its possible clinical application to various disorders in vocal folds. However, a more detailed description about the software and the mathematical formulation used in this system is needed for the reproduction of similar systems. The composition of hardwares, user-interface and detail procedures including mathematical equations in videostrobokymography software is presented in this study. As an initial clinical trial, videostrobokymography was applied to the preoperative and postoperative videostroboscopic images of 15 patients with Reinke's edema. On preoperative examination, videostrobokymograms showed irregular pattern of mucosal wave and, in some patients, a relatively constant glottic gap during phonation. After the operation, the voice quality of all patients was improved in acoustic and aerodynamic assessments, and videostrobokymography showed clearly improved mucosal waves (change in open quotient: mean +/- SD= 0.11 +/- 0.05).

CoMed: a real-time collaborative medicine system

CoMed is a prototype of a real-time collaborative medicine system that allows medical specialists to share patient records and to communicate with each other on the Internet. CoMed consists of a multimedia medical database containing relevant information about laryngeal diseases and a real-time collaboration system including a teleconferencing system, a whiteboard and a chatting system. CoMed is web-based. We adopted the object database O2 and CORBA technologies for the multimedia medical database. Therefore, our system can provide the flexibility, extensibility and location transparency of patient databases. We developed a SeeYou Active X control for the teleconferencing system and a Java applet for the whiteboard and chatting system. CoMed improves the efficiency of the overall system by separating the servers on a UNIX machine and a Windows NT machine. CoMed can be utilized for stand-alone research, for collaborative consultations among medical specialists and for a telemedicine in participation with the patients and medical specialists. Our system can be extended easily into other types of the collaborative systems, such as collaborative distance learning, collaborative science system, etc.

Videostrobokymography: a new method for the quantitative analysis of vocal fold vibration

OBJECTIVES

To develop a new analysis method for the quantitative assessment of vibration of the vocal folds, using conventional videostroboscopic image data.

METHODS

We used prerecorded videostroboscopic images to evaluate quantitatively the vibration of the vocal folds. Successive images were converted as digital images by means of an image-grabbing board, processed for analysis, and reconstructed as kymograms by rearranging the same lines of all processed images along the time axis.

RESULTS

We developed a new technique for evaluating the vibration of the vocal folds. The vibrations of multiple vocal fold regions were easily and objectively evaluated by this technique. The objective parameters, such as open quotient and asymmetry index, could be obtained easily using this technique.

CONCLUSIONS

Videostrobokymography demonstrated objectively the vibrations of several vocal fold regions at the same time. This technique has the potential to be a new tool to analyze and monitor the pathological changes and treatment results of vocal fold movement in a more refined quantitative fashion, using videostroboscopic images.

Development of videostrobokymography for the quantitative analysis of laryngeal vibratory pattern

We developed a new analysis technique for the assessment of irregular vibratory movement of vocal folds. Successive frames of pre-recorded video images from videostroboscopy were transferred to computer memory and vibratory track of one selected point was described as a waveform by displaying the same lines of all frames along the vertical direction. Glottal area waveform, which was normalized with glottal length, was composed to quantitatively assess the overall vibratory pattern of vocal folds. By applying this technique, irregular vibratory patterns of multiple regions, such as asynchronized registration of glottal cycles, could be easily visualized. It would be possible to monitor and analyze the pathologic changes of vocal fold movement by means of this newly developed system.
