Coptidis Rhizoma, as a bulk medicinal material, is in great demand in clinical practice. Its quality is uneven in the market due to the mixture of genuine, counterfeit and adulterants. Therefore, it is particularly important to establish a quality control system for Coptidis Rhizoma. Based on the concept of Chinese medicine quality marker(Q-marker), the potential quality markers of Coptidis Rhizoma were analyzed and predicted from the perspective of chemistry and pharmacology. The sources of the Q-markers of Coptidis Rhizoma were identified by literature retrieval. The potential Q-markers were then screened through the visualization of the "components-targets-pathways" network. High performance liquid chromatography(HPLC) was used to establish a multi-indicator qualitative and quantitative control method featuring fingerprints for 10 batches of Coptidis Rhizoma. A supervised mode of orthogonality partial least squares method-discriminant analysis(OPLS-DA) was used to screen the main marker components that caused differences between groups. The literature review results showed that the alkaloids were the main source of Coptidis Rhizoma Q-markers.The fingerprints of 13 common peaks were successfully established, and berberine, palmatine, berberine and epiberberine were selected as Q-markers of Coptidis Rhizoma, and their contents were determined.Based on the concept of the Q-marker of traditional Chinese medicine, the four components can be selected as the Q-marker of Coptidis Rhizoma after comprehensive consideration. The results of this study are not only conducive to the quality evaluation of Coptidis Rhizoma on the market, but also provide a reference for the overall quality control of Coptidis Rhizoma and lay foundation for the future exploration of the mechanism of Coptidis Rhizoma.

Objective: To analyze and summarize the diagnosis, treatment and prognosis of granulomatosis with polyangiitis (GPA) with nasal symptoms as the first clinical manifestation. Methods: The data of 18 patients of GPA with nasal mucosal symptoms as the first clinical manifestation from the Department of Otorhinolaryngology Head and Neck Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University between 2005 and 2019 was collected, including 8 males and 10 females, aged from 5 to 68 years. Nasal endoscopy, imaging examination, laboratory examination, immunological and histopathological examination of nasal mucosa were completed. All patients were treated with glucocorticoid combined with cyclophosphamide and were followed up for 2 to 15 years. Descriptive statistical method was used for analysis. Results: All the 18 patients had the nasal mucosal symptoms as the first clinical manifestation, including nasal obstruction, running nose and epistaxis. Nasal endoscopy showed swelling, erosion, scab and bleeding of nasal mucosa, and 6 cases had nasal septal perforation. Nasal sinus CT scan showed high density shadow of sinus, as well as hyperostosis and osteosclerosis. CT imaging features of pulmonary showed nodular lesion or patchy infiltration in 12 patients and cavitation was found in 6 cases. Laboratory results showed that 13 cases were positive for anti-neutrophil cytoplasmic antibodies (ANCA), and 5 cases were negative. During follow-up period, thirteen patients were symptomatic controlled and survived; two patients died of disease progression; one patient gave up treatment and died; two patients were lost to follow-up. Conclusions: Nasal symptoms are the first clinical manifestation of GPA. Early diagnosis and early treatment with glucocorticoid combined with cyclophosphamide can effectively improve the survival rate.

ObjectiveTo understand the situation of nosocomial infection in cancer hospitals and its changing trend, so as to provide a basis for adjusting the focus of nosocomial infection prevention and control in cancer hospitals. MethodsData of nosocomial infection quality control indices of Sun Yat-sen University Cancer Center from 2019 to 2021 were obtained through the nosocomial infection monitoring system, and the changes of these indices across the three years were analyzed by Chi-square test and Cochran-Armitage trend test. ResultsFrom 2019 to 2021, the incidence rates of nosocomial infection in this hospital were 0.80%, 0.78% and 0.57%, which decreased significantly year by year (P<0.001). Among them, surgical site and respiratory system infection were more common, accounting for 35.75% and 31.08%, respectively. Gram-negative bacteria and fungi were the main pathogens. The incidence rate of multidrug-resistant bacteria in hospital increased year by year, from 0.08‰ to 0.14‰ (P<0.001), among which methicillin-resistant staphylococcus aureus, carbapenem-resistant Enterobacter and bacteria producing ultra-broad spectrum β-lactamase (ESBLs) bacteria increased significantly. The incidence rates of three-tube associated infections were no different across 3 years (P>0.05), which were still at high levels. ConclusionFrom 2019 to 2021, the prevention and control of nonsocomial infection in the cancer hospital has been improved overall. Meanwhile, the infections of respiratory system and surgical sites, ESBLs related multidrug-resistant bacteria and three-tube are weak links in cancer specialized hospitals, which need to be emphasized and improved.
