Objective: Coronavirus Disease 2019 (COVID-19) has been diagnosed as an epidemic disease characterized by cold and dampness pathogens in TCM clinic. Due to many Chinese medicines with different functions were used in the treatment of COVID-19, it is very important to find the law of application of damp-removing traditional Chinese medicine with high frequency application, with view to providing a reference for the use and research of Chinese medicine to further control the pandemic. Methods: The publicly released diagnosis and treatment programs issued by the National Health Commission and Health Commission of provinces, autonomous regions and municipalities, and Chinese herbs prescription information in these were collected, a database was established, and Excel and Graphpad 8.0 software were used to analyze the frequency of use of various Chinese medicines, the frequency and property characters including five flavors (bitter, pungent, sweet, sour, and salty) and four natures (warm, hot, cool, and cold) and channel tropisms of Chinese medicine for removing dampness. Results: A total of 137 prescriptions of Chinese medicine for treating COVID-19 were collected, including 178 TCMs showing functions of resolving phlegm, relieving cough and asthma, resolving dampness, clearing damp and inducing dieresis, clearing heat, tonifying deficiency, and relieving exterior syndrome, in which the TCMs with the first four functions that we called the dampness-removing TCMs, accounted for 35.78%. Also a number of TCMs in the rest functions showed removing-dampness. The first four functions were divided into subfunctions including aromatic resolving dampness, clearing heat and drying dampness, drying dampness and tonifying spleen qi, drying dampness and removing phlegm, inducing diuresis and relieving swelling, inducing diuresis and relieving exterior syndrome. Among them, the most frequently used TCMs was Ephedrae Herba, followed by Citri Reticulatae Pericarpium, Pogostemonis Herba, Pinelliae Rhizoma, Poria, Scutellariae Radix, and Atractylodis Rhizoma. The property character analysis in the dampness-removing TCMs showed that bitter and pungent were largely present and sour and astringent were absent, warm and hot were dominant; And the lung, spleen, stomach, large intestine, bladder were main channel tropisms. Conclusion: Dampness-removing TCMs are the first important type of traditional Chinese medicine to be considered in the treatment of COVID-19 in Chinese medicine. The application of dampness-removing TCMs in the treatment of COVID-19 needs to be combined with its application law. This study may provide meaningful and useful information on further research to investigate the effective compounds from the dampness-removing Chinese medicine with high frequency application, and also provide a reference for the clinical treatment of COVID-19 accurately against dampness evil with dampness-removing traditional Chinese medicines.

The present study was aimed to investigate the effects of orexin-A and orexin-1 receptor (OX1R) antagonist injected into the fourth ventricle of rats on food-intake and spontaneous physical activity (SPA). Obese rat model was induced by high fat diet. Different doses of orexin-A or SB334867, an OX1R antagonist, were injected into the fourth ventricle of obese and normal rats respectively. SPA and food intake were monitored for 4 h after injection in both light and dark environment. In the light measurement cycle, different doses of orexin-A significantly stimulated feeding and SPA in all injected rats, and the animals' responses showed a dose-dependent manner (P < 0.05-0.01), and compared with those of normal rats, the orexin-A induced food intake and SPA were more pronounced in obese rats. In the dark measurement cycle, different doses of orexin-A had no obvious effect on food intake and SPA in both normal and obese rats (P > 0.05). In the light cycle, different doses of SB334867 significantly decreased food intake and SPA in all rats during 0-2 h and 2-4 h after injection (P < 0.05), but the food intake and SPA in obese rats were significantly greater than those of normal rats. In the dark cycle, different doses of SB334867 showed no obvious effect on food intake and SPA of normal and obese rats (P > 0.05). These results suggest that fourth cerebral ventricle nuclei may be one target for orexin-A and light condition may play an important role in orexin-A and OX1R physiological functional processes.

<p><b>OBJECTIVE</b>To evaluate the expression of nuclear factor-kappaB (NF-kappaB), Ki-67 and matrix metalloproteinase-9 (MMP-9) in calcifying odontogenic cyst (COC), in order to investigate the proliferation and invasion of COC.</p><p><b>METHODS</b>Twenty-six cases of COC were classified into calcifying cystic odontogenic tumor (CCOT), dentinogenic ghost cell tumor (DGCT) and ghost cell odontogenic carcinoma (GCOC) based on the WHO classification of odontogenic tumors in 2005. The specimens of COC and 10 classic ameloblastoma (AB) were examined immunohistochemically to determine the expression of NF-kappaB p65, Ki-67 and MMP-9.</p><p><b>RESULTS</b>NF-kappaB was mainly detected in the cytoplasm of most tumor cells, but was only detected in the nucleus of few tumor cells (rate of nuclear staining < 1%). The expression of Ki-67 was significantly higher in GCOC than in CCOT (P < 0.001), DGCT (P < 0.05) and AB (P < 0.005). MMP-9 was detected both in tumor cells and stromal cells. GCOC showed significantly higher percentage of MMP-9 positive cases in stromal cells than CCOT, DGCT and AB (P < 0.05).</p><p><b>CONCLUSIONS</b>NF-kappaB may minimally affect the progression and invasion of COC. GCOC shows significantly higher proliferative activity and aggressiveness than CCOT and DGCT. MMP-9 in stroma may play a key role in the invasion of GCOC.</p>
