ObjectiveTo perform a predictive analysis of the quality marker（Q-Marker） for the anticoagulant activity of Kunning granules. MethodThe chemical components of Kunning granules were analyzed by ultra high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry（UHPLC-Q-TOF-MS/MS） on a Waters ACQUITY UPLC HSS T3 column（2.1 mm×100 mm， 1.8 μm） with the mobile phase of acetonitrile（A）-25 mmol∙L^-1 ammonium acetate aqueous solution（B） for gradient elution （0-5 min， 5%-22%A； 5-10 min， 22%-30%A； 10-15 min， 30%-95%A； 15-20 min， 95%-5%A； 20-30 min， 5%A）， flow rate of 0.2 mL∙min^-1， column temperature at 30 ℃， injection volume of 1 μL， electrospray ionization（ESI）， positive and negative ion detection modes. Interaction analysis between the targets of chemical components and the targets of abnormal uterine bleeding（AUB） was performed by network pharmacology， and the key components were screened through network topology analysis. The fingerprints of 10 batches of Kunning granules were established by high performance liquid chromatography（HPLC）， the anticoagulant activity of the granules was determined by blood coagulation method and fibrinogen plate method， and the spectrum-effective relationship was established. The components co-occurring in the topological analysis and spectrum-effective relationship were selected as Q-Markers， and their anticoagulant activities were verified and confirmed. ResultA total of 475 chemical components were identified from Kunning Granule， of which 22 key components such as salvianolic acid B， paeoniflorin， naringin and neohesperidin， were the potential material basis for the treatment of AUB. The spectrum-effective analysis showed that peaks 7（paeoniflorin）， 9（naringin）， 10（neohesperidin） and 11（salvianolic acid B） were the optimal principal components， and in vitro activity test showed that these four components could better characterize their anticoagulant activity. ConclusionSalvianolic acid B， paeoniflorin， neohesperidin and naringin may be Q-Markers for the anticoagulant activity of Kunning granules.

Objective     To analyze the clinicopathological characteristics of thymoma patients and the influencing factors for prognosis. Methods     Thymoma patients who received treatment in Sichuan Cancer Hospital from March 2015 to March 2021 were collected. Clinical data of the patients were analyzed using Kaplan-Meier and Cox regression analyses. Results     A total of 177 patients were included. There were 89 males and 88 females aged 17-88 (52.3±13.0) years, including 160 surgical patients and 17 non-surgical patients. There were 160 patients survived, 17 died of thymoma, and 5 had recurrence and metastasis. Overall, the 1-year, 3-year and 5-year progression-free survival rates were 94.4%, 88.7%, 88.1%, respectively; the 1-year, 3-year and 5-year overall survival rates were 94.9%, 91.5%, 91.0%, respectively. The Kaplan-Meier analysis showed that World Health Organization classification, clinical symptoms, Masaoka-Koga staging, treatment methods and surgery were statistically associated with progression-free survival; clinical symptoms, age, treatment methods and surgery were statistically associated with overall survival (P<0.05). Patients with younger age (P=0.018), without clinical symptoms (P=0.039), and with surgical treatment (P=0.004) had higher overall survival rates; those patients undergoing surgery had a higher progression-free survival rate (P=0.002). Conclusion     Age, clinical symptoms and surgical treatment are independent factors influencing the prognosis of patients with thymoma.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.
