ObjectiveTo systematically evaluate the efficacy and safety of Qi-reinforcing and blood-activating/stasis-expelling Chinese patent medicines in the treatment of coronary microvascular disease (CMD). MethodsPubMed, Cochrane Library, CNKI, Wanfang Data, and VIP were searched for the randomized controlled trials (RCTs) on the treatment of CMD with Chinese patent medicines for reinforcing Qi and activating blood/expelling stasis with the time interval from inception to December 31, 2023. The primary outcome indicators included the index of microcirculatory resistance (IMR), coronary flow reserve (CFR), and corrected TIMI flow frame count (cTFC). The secondary outcome indicators included symptomatic efficacy, left ventricular ejection fraction (LVEF), hypersensitive C-reactive protein (hs-CRP), nitric oxide (NO), and adverse events. Cochrane risk-of-bias assessment tool 2.0 (RoB 2.0) and Stata 17.0 were used for literature quality evaluation and meta-analysis of the included RCTs. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used to evaluate the quality of evidence. ResultsA total of 36 RCTs were included in this study, involving 3 029 patients. Compared with conventional Western medicine alone, the combined use of Chinese patent medicines for reinforcing Qi and activating blood/expelling stasis and Western medicine reduced the IMR [mean difference (MD)=-5.93, 95% confidence interval (95%CI) [-8.73,-3.14], n=382, P<0.01], cTFC (MD=-9.35, 95%CI [-13.94,-4.76], n=618, P<0.01), and hs-CRP [standard mean difference (SMD)=-1.50, 95%CI [-1.90,-1.11], n=1 483, P<0.01], improved the CFR (SMD=1.14, 95%CI [0.08,2.19], n=304, P=0.03), symptomatic efficacy [relative risk (RR)=1.36, 95%CI [1.21,1.53], n=756, P<0.01], LVEF (MD=4.39, 95%CI [2.31,6.47], n=533, P<0.01), and NO (SMD=3.16, 95%CI [2.07,4.25], n=946, P<0.01) of CMD patients. In terms of safety, the combined therapy reduced the occurrence of adverse events in CMD patients (RR=0.49, 95%CI [0.29,0.82], n=591, P=0.01). GRADE showed moderate quality evidence for adverse events, low quality evidence for cTFC, symptomatic efficacy, LVEF, and NO, and very low quality evidence for IMR, CFR, and hs-CRP. ConclusionBased on microcirculatory function indicators, the combined use of Qi-reinforcing and blood-activating/stasis-expelling Chinese patent medicines and Western medicine may further improve the coronary microvascular function in CMD patients with good safety. The above conclusions remain to be verified with high-quality clinical trials.

Currently,human health due to corona virus disease 2019(COVID-19)pandemic has been seriously threatened.The coronavirus severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)spike(S)protein plays a crucial role in virus transmission and several S-based therapeutic approaches have been approved for the treatment of COVID-19.However,the efficacy is compromised by the SARS-CoV-2 evolvement and mutation.Here we report the SARS-CoV-2 S protein receptor-binding domain(RBD)inhibitor licorice-saponin A3(A3)could widely inhibit RBD of SARS-CoV-2 variants,including Beta,Delta,and Omicron BA.1,XBB and BQ1.1.Furthermore,A3 could potently inhibit SARS-CoV-2 Omicron virus in Vero E6 cells,with EC50 of 1.016 pM.The mechanism was related to binding with Y453 of RBD deter-mined by hydrogen-deuterium exchange mass spectrometry(HDX-MS)analysis combined with quan-tum mechanics/molecular mechanics(QM/MM)simulations.Interestingly,phosphoproteomics analysis and multi fluorescent immunohistochemistry(mIHC)respectively indicated that A3 also inhibits host inflammation by directly modulating the JNK and p38 mitogen-activated protein kinase(MAPK)path-ways and rebalancing the corresponding immune dysregulation.This work supports A3 as a promising broad-spectrum small molecule drug candidate for COVID-19.

Medical Journal of Peking Union Medical College Hospital 2024;15(2):387-393
Traditional pancreatobiliary endoscopy surgery is limited by the fact that capturing image information is time-consuming, inefficient, and susceptible to the level of the practitioner. Artificial intelligence, however, provides an efficient and accurate method of automatic image recognition for pancreaticobiliary endoscopic surgery, thus assisting clinicians to achieve rapid and accurate clinical predictions and guiding clinical decision-making. Moreover, artificial intelligence has great potential for applications in many aspects such as quality control and training of procedure. This paper provides an overview of the current status and research progress in the application of artificial intelligence in pancreatic and biliary endoscopic techniques, with the hope of offering new ideas and methods for improving the current clinical diagnosis and treatment pattern and realizing precision medicine for pancreatobiliary diseases.

Zearalenone(ZEN) is a toxic metabolite produced by Fusarium culmorum, F. graminearum, F. tricinctum, and other fungi, with estrogenic characteristics. Exposure to or ingestion of ZEN during pregnancy can cause reproductive dysfunction, miscarriage, stillbirth, and malformation, and seriously endanger human life and health. The detection methods for ZEN in the Chinese Pharmacopoeia(2020 edition) are liquid chromatography(LC) and liquid chromatography-mass spectrometry(LC-MS), and it is stipulated that ZEN should not exceed 500 μg in 1 000 g of Coicis Semen. Although these detection methods by instruments can achieve the qualitative and quantitative analysis of ZEN in Coicis Semen, their high detection cost and long periods hinder the rapid screening of a large number of samples in the field. In this study, the synthesized ZEN hapten was conjugated with bovine serum albumin(BSA) and ovalbumin(OVA) to obtain the complete ZEN antigen. By virtue of antibody preparation techniques, ZEN monoclonal antibody 4F6 was prepared, which showed 177.5%, 137.1%, and 109.7% cross-reactivity with ZEN structural analogs zearalanol, zearalenone, and α-zearalenol, respectively, and no cross-reactivity with other fungal toxins such as aflatoxin. Direct competitive enzyme-linked immunosorbent assay(dcELISA) based on ZEN monoclonal antibody 4F6 was developed for the determination of ZEN in Coicis Semen with an IC_(50) of 1.3 μg·L~(-1) and a detection range of 0.22-21.92 μg·L~(-1). The recoveries were 83.91%-105.3% and the RSD was 4.4%-8.0%. The established dcELISA method was used to determine the ZEN residuals in nine batches of Coicis Semen samples, and the results were validated by LC-MS. The correlation between the two detection methods was found to be 0.993 9, indicating that the established dcELISA could be used for the rapid qualitative and quantitative detection of ZEN residuals in Coicis Semen.

Objective: To characterize the incidence density of systematic lupus erythematosus (SLE) in Yinzhou District of Ningbo from 2016 to 2021, and compare the age and gender specific differences. Methods: A retrospective cohort study was conducted based on the related data from 2015 to 2021 collected from the Health Information Platform of Yinzhou. Suspected SLE cases in local residents were identified by fuzzy matching of International Classification of Diseases 10th edition code "M32" or Chinese text "lupus". The classification criteria from Systemic Lupus International Collaboration Clinics-2012 and The European League Against Rheumatism/American College of Rheumatology-2019 were used for case verification. SLE cases were identified with specific algorithm based on verification results, and new cases were identified with 1 year as the washout period. The incidence density and 95%CI were estimated by Poisson distribution. Results: From 2016 to 2021, a total of 1 551 921 permanent residents were registered in Yinzhou, in whom 51.52% were women. The M(Q1,Q3) age at enrollment was 40.38 (27.54, 53.54) years. The M(Q1,Q3) of follow-up person-years was 3.83 (0.41, 5.83) years. There were 451 new SLE cases, in which 352 were women (78.05%). The 6-year incidence density was 8.14/100 000 person-years (95%CI: 7.41/100 000 person-years-8.93/100 000 person-years) for the total population, 3.68/100 000 person-years (95%CI: 2.99/100 000 person-years-4.48/100 000 person-years) for men and 12.37/100 000 person-years (95%CI: 11.11/100 000 person-years- 13.73/100 000 person-years) for women. The incidence density in men appeared a small peak at 20-29 years old, and began to increase with age from 40 years old. The incidence density in women was highest in age group 20-29 years (16.57/100 000 person-years) and remained to be high until 30-79 years old. The incidence density of SLE in Yinzhou show no significant temporal trend from 2016 to 2021 (men: P=0.848; women: P=1.000). Conclusions: The incidence density of SLE in Yinzhou from 2016 to 2021 was similar to those of other areas in China. SLE has a high incidence in women, especially in the young and elderly, suggesting that more attention should be paid to the diagnosis and treatment of SLE in women.
