OBJECTIVE: To evaluate the efficacy and safety of Huashi Baidu Granules (HSBD) in treating patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant. METHODS: A single-center retrospective cohort study was conducted during COVID-19 Omicron epidemic in the Mobile Cabin Hospital of Shanghai New International Expo Center from April 1st to May 23rd, 2022. All COVID-19 patients with asymptomatic or mild infection were assigned to the treatment group (HSBD users) and the control group (non-HSBD users). After propensity score matching in a 1:1 ratio, 496 HSBD users of treatment group were matched by propensity score to 496 non-HSBD users. Patients in the treatment group were administrated HSBD (5 g/bag) orally for 1 bag twice a day for 7 consecutive days. Patients in the control group received standard care and routine treatment. The primary outcomes were the negative conversion time of nucleic acid and negative conversion rate at day 7. Secondary outcomes included the hospitalized days, the time of the first nucleic acid negative conversion, and new-onset symptoms in asymptomatic patients. Adverse events (AEs) that occurred during the study were recorded. Further subgroup analysis was conducted in vaccinated (378 HSBD users and 390 non-HSBD users) and unvaccinated patients (118 HSBD users and 106 non-HSBD users). RESULTS: The median negative conversion time of nucleic acid in the treatment group was significantly shortened than the control group [3 days (IQR: 2-5 days) vs. 5 days (IQR: 4-6 days); P<0.01]. The negative conversion rate of nucleic acid in the treatment group were significantly higher than those in the control group at day 7 (91.73% vs. 86.90%, P=0.014). Compared with the control group, the hospitalized days in the treatment group were significantly reduced [10 days (IQR: 8-11 days) vs. 11 days (IQR: 10.25-12 days); P<0.01]. The time of the first nucleic acid negative conversion had significant differences between the treatment and control groups [3 days (IQR: 2-4 days) vs. 5 days (IQR: 4-6 days); P<0.01]. The incidence of new-onset symptoms including cough, pharyngalgia, expectoration and fever in the treatment group were lower than the control group (P<0.05 or P<0.01). In the vaccinated patients, the median negative conversion time and hospitalized days were significantly shorter than the control group after HSDB treatment [3 days (IQR: 2-5 days) vs. 5 days (IQR: 4-6 days), P<0.01; 10 days (IQR: 8-11 days) vs. 11 days (IQR: 10-12 days), P<0.01]. In the unvaccinated patients, HSBD treatment efficiently shorten the median negative conversion time and hospitalized days [4 days (IQR: 2-6 days) vs. 5 days (IQR: 4-7 days), P<0.01; 10.5 days (IQR: 8.75-11 days) vs. 11.0 days (IQR: 10.75-13 days); P<0.01]. No serious AEs were reported during the study. CONCLUSION HSBD treatment significantly shortened the negative conversion time of nuclear acid, the length of hospitalization, and the time of the first nucleic acid negative conversion in patients infected with SARS-COV-2 Omicron variant (Trial registry No. ChiCTR2200060472).

For patients with severe coronary thrombosis burden,when conventional methods still cannot restore ideal blood flow,excimer laser coronary angioplasty(ELCA)can be used as an important auxiliary method for percutaneous coronary intervention(PCI).It can reduce the occurrence of slow blood flow or no-reflow,increase coronary blood flow,improve myocardial perfusion,and achieve higher immediate and clinical success rates.This article introduced the diagnosis and treatment of 3 patients with massive right coronary artery thrombosis treated with ELCA combined with thrombus aspiration.All 3 patients successfully opened blood vessels,significantly reduced the thrombus load,and achieved good immediate and clinical effects.No complications such as vascular perforation and cardiac tamponade occurred during the treatment.

Objective:To investigate the clinical features and risk factors of multiple organ dysfunction syndrome (MODS) caused by wasp sting.Methods:A retrospective cohort study was conducted to collect the general data of wasp sting patients who had a clear history of wasp sting disease and clinical manifestations from June 2016 to December 2020 and were first diagnosed as wasp sting in hospital. Patients with hematological diseases, malignant tumors, severe liver and kidney dysfunction, cardiac insufficiency, and patients who had received hormone therapy before admission were excluded. Patients who were unable to obtain effective laboratory results due to hemolysis or other reasons within 48 h of admission were also excluded. The white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), hemoglobin count (HB), myoglobin (Mb/MYO), activated partial thromboplastin time (APTT), albumin (ALB), K, Na, and Cl of the blood samples collected within 48 h after admission were recorded. Patients were divided into the MODS group and non-MODS group according to whether MODS occurred during hospitalization. Uni- and multivariate analysis were used to analyze the factors affecting the occurrence of MODS in wasp sting patients during hospitalization, and the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive effect of myoglobin level on the occurrence of MODS in wasp sting patients during hospitalization.Results:Mb, WBC, NEU, APTT and serum potassium in the MODS group [3890.00 (1416.90-4057.00) ng/mL, (21.99 ± 8.18) × 10 9/L, (19.61 ± 7.33)× 10 9/L, (93.75 ± 45.77) s, and (4.99 ± 0.95) mmol/L] were significantly higher than those in the non-MODS group [73.50 (34.30-264.20) ng/mL, (13.40 ± 4.14)× 10 9/L, (11.18±4.73)× 10 9/L, (37.00 ± 17.16) s, and (4.05 ± 0.56) mmol/L] (all P < 0.05); blood chlorine and ALB [(101.50 (98.25-105.00) mmol/L and (35.36 ± 6.44) g/L)] were significantly lower than those in the non-MODS group [(105.00 (103.00-107.00) mmol/L and (40.71 ± 5.48) g/L)] (all P < 0.05). Multivariate logistic regression analysis showed that NEU ( OR = 0.729, 95% CI: 0.542~0.981), Mb ( OR = 0.999, 95% CI: 0.998~1.000), and APTT ( OR = 0.951, 95% CI: 0.921~0.982) were independent risk factors for MODS in wasp sting patients. ROC curve analysis showed that NEU, Mb and APTT could be used to evaluate the occurrence of MODS in wasp sting patients. Among them, Mb had the highest predictive value (AUC = 0.950, 95 % CI: 0.891~0.982). The optimal cutoff value of Mb for predicting the occurrence of MODS in wasp sting patients was 515.30 ng/mL, and the corresponding sensitivity and specificity were 90.62% and 87.23%, respectively. Conclusion:Mb is an independent risk factor for MODS in wasp sting patients, which can be used as a good predictor of MODS in wasp sting patients.

This study aimed to explore the anti-depressant components of Rehmanniae Radix and its action mechanism based on network pharmacology combined with molecular docking. The main components of Rehmanniae Radix were identified by ultra-high performance liquid chromatography-quadrupole/Orbitrap high resolution mass spectrometry(UPLC-Q-Orbitrap HRMS), and the related targets were predicted using SwissTargetPrediction. Following the collection of depression-related targets from GeneCards, OMIM and TTD, a protein-protein interaction(PPI) network was constructed using STRING. GO and KEGG pathway enrichment analysis was performed by Metascape. Cytoscape 3.7.2 was used to construct the networks of "components-targets-disease" and "components-targets-pathways", based on which the key targets and their corresponding components were obtained and then preliminarily verified by molecular docking. Rehmanniae Radix contained 85 components including iridoids, ionones, and phenylethanoid glycosides. The results of network analysis showed that the main anti-depressant components of Rehmanniae Radix were catalpol, melittoside, genameside C, gardoside, 6-O-p-coumaroyl ajugol, genipin-1-gentiobioside, jiocarotenoside A1, neo-rehmannioside, rehmannioside C, jionoside C, jionoside D, verbascoside, rehmannioside, cistanoside F, and leucosceptoside A, corresponding to the following 16 core anti-depression targets: AKT1, ALB, IL6, APP, MAPK1, CXCL8, VEGFA, TNF, HSP90 AA1, SIRT1, CNR1, CTNNB1, OPRM1, DRD2, ESR1, and SLC6 A4. As revealed by molecular docking, hydrogen bonding and hydrophobicity might be the main action forms. The key anti-depression targets of Rehmanniae Radix were concentrated in 24 signaling pathways, including neuroactive ligand-receptor interaction, neurodegenerative disease-multiple diseases pathway, phosphatidylinositol 3-kinase/protein kinase B pathway, serotonergic synapse, and Alzheimer's disease.

Objective: To observe the gadolinium imaging findings of inner ear in patients with sudden deafness and to analyze its clinical features. Methods: From November 2017 to July 2020, 21 patients with sudden deafness in the People's Hospital of Dongsheng District, Ordos City were selected as the research objects, including 14 males and 7 females, aged 36-76 years, with a median age of 50 years. The course of disease was 1-19 days, with an average of 5.5 days. The patients received audiology tests, laboratory examination, and intravenous gadolinium angiography, each of whom was scanned twice by 3D-FLAIR sequence: once before intravenous gadolinium injection, and once again 4.5-6.0 h after intravenous gadolinium injection. The following corresponding clinical treatment was given. The imaging manifestations and clinical features were observed. Results: Among 21 cases of sudden deafness in acute stage, the signal intensity of 11 cases was significantly higher than that of the contralateral ear, and 2 cases had vestibular labyrinthine hydrops. In laboratory examination, only 2 cases of total deafness had increased WBC count and faster erythrocyte sedimentation rate, and the rest had no abnormality. The hearing types of 21 patients with sudden deafness were: total deafness in 8 cases, flat decline in 10 cases, low frequency decline in 1 case, high frequency decline in 2 cases. The total effective rate was 57% (12/21). The hearing types of 11 patients with abnormal gadolinium angiography were total deafness in 5 cases, flat decline in 5 cases and high frequency decline in 1 case. The total effective rate was 64% (7/11). Conclusion: Gadolinium angiography is abnormal in some patients with sudden deafness, and the permeability of blood labyrinth barrier may be increased, which is worthy of further study.

Uterine sarcoma is a rare uterine malignant tumor characterized by extremely aggressive behavior with a high recurrence rate and poor prognosis. It remains very challenging to distinguish uterine sarcomas from uterine fibroids prior to surgery because of the similar clinical manifestations and the lack of specific imaging features and tumor markers. An integrated analysis algorism including risk factors,symptoms,imaging analysis(pelvic ultrasound and MRI),and endometrial biopsy is helpful for the preoperative differential diagnosis between uterine sarcomas and uterine leiomyomas.
