Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Based on data mining technology, the acupoints compatibility rules of acupuncture for depression diseases were explored. The randomized controlled trial (RCT) articles regarding acupuncture for depression diseases published from establishment of database to September 2nd, 2022 were searched in CNKI database, Wangfang database, VIP database, SinoMed database, PubMed, EMbase, Web of Science and Cochrane Library. The use frequency of acupoints, meridian tropism, selection of special acupoints and acupoint association rules for five common depression diseases, including primary depression, post-stroke depression, menopausal syndrome, psychoneurosis and anxiety disorder, were analyzed by Python programming language. Cytoscape software was used to analyze the acupoint association and the disease-acupoint co-occurrence network. As a result, totally 387 articles were included, and 319 acupoints prescriptions for the above five common depression diseases were extracted, involving 159 acupoints. The use frequency of acupoints was 2 574 times in total. The frequently-used acupoints were Baihui (GV 20), Sanyinjiao (SP 6), Taichong (LR 3), Neiguan (PC 6), Shenmen (HT 7), Yintang (GV 24⁺), Zusanli (ST 36), Hegu (LI 4), Sishencong (EX-HN 1) and Taixi (KI 3), etc. The frequently involved meridians were the governor vessel, foot-taiyang bladder meridian, foot-taiyin spleen meridian, and foot-jueyin liver meridian. The frequency of the special acupoints from high to low was crossing points, five-shu points, yuan-primary points, back-shu points, luo-connecting points, and eight confluent points, etc, which were often used in combination with "Baihui (GV 20)-Yintang (GV 24⁺)" (the highest degree of association). At the same time, the analysis of the co-occurrence network of depression diseases and acupoints showed that the core acupoints group of acupuncture for depression diseases were Baihui (GV 20), Taichong (LR 3), Shenmen (HT 7), Zusanli (ST 36), Neiguan (PC 6) and Sanyinjiao (SP 6). In conclusion, acupuncture treatment for depression diseases has gradually formed a rule of acupoint compatibility, with special acupoint as the main body and "unblocking the governor vessel, and regulating the spirit and qi " as the main therapeutic principle.

Human RNase A (human RNase A) superfamily contains 13 members (RNase 1~RNase 13) with different biological activities. In addition to the conserved catalytic sequence, its protein structure also has a significant diversity of sequences, which determines that human ribonuclease A can exert biological functions other than ribonuclease activity. Human RNase A superfamily members are expressed in various immune cells such as eosinophils, neutrophils, monocytes, and macrophages and can be secreted to exert various biological functions, including anti-microbial activity, promote host defense, participate in angiogenesis and sperm maturation, etc. Some members of the human ribonuclease A superfamily can exert antimicrobial and antiparasitic activities through direct actions such as hydrolysis of viral RNA, inhibition of viral replication, destruction of bacterial cell walls, promotion of microbial aggregation, damage to parasitic cell membranes and mitochondrial membranes, and indirect actions mediated by host innate immune cells, thereby participating in host defense. This article reviews the antimicrobial (including viruses, bacteria, and fungi) and antiparasitic activities of human ribonuclease A and their mechanisms of action. It also prospects the prospects of human ribonuclease A as an active antimicrobial substance and innate immune molecule for the treatment of severe and drug-resistant microbial infections.

Objective:To explore the biological basis underlying the different syndromes of nontraumatic osteonecrosis of the femoral head (NONFH) according to the molecular interaction network associated with syndromes and the corresponding prescriptions. Method:A total of 30 NONFH patients and 10 healthy controls were enrolled in the present study. The gene expression profiles associated with different syndromes of NONFH were detected by microarray analysis. Then, the molecular interaction networks of the differentially expressed genes of different syndromes were constructed to identify the crucial syndrome-related genes. After collecting the phenotype-related genes and the candidate targets of the corresponding prescriptions of different syndromes from Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0 (http://www.tcmip.cn/), the molecular interaction network associated with syndromes and the corresponding prescriptions were constructed and the biological basis of each syndrome was analyzed by functional enrichment analysis. Result:The crucial genes associated with the phlegm-stasis blocking collateral syndrome were mainly involved into the bone and lipid metabolism, and the regulation of immune-inflammation balance and circulation. Consistently, the candidate targets of the corresponding prescription-Jianpi Huogu prescription might play roles in the metabolism of osteogenesis, dissipating phlegm, activating circulation to remove blood stasis, relieving pain and inflammatory response. In addition, our data revealed that the stagnation of meridians syndrome-related genes could be mainly involved into the regulation of circulation and inflammatory response, as well as the metabolism of lipid and bone. Accordingly, the corresponding prescription of this syndrome-Huoxue Tongbi Formula could exert the regulatory effects on osteogenesis and inflammatory response, as well as the activation of the circulation and qi-invigorating. Moreover, the crucial genes associated with the liver and kidney deficiency syndrome played roles in various pathological processes during NONFH, such as the abnormal bone and lipid metabolisms, the immune-inflammation imbalance, and the blocked blood circulation, which were in line with our findings on the pharmacological mechanisms of the corresponding prescription of this syndrome-Bushen Zhuanggu formula. Conclusion:The current study indicated that the phlegm-stasis blocking collateral syndrome may be mainly associated with the abnormal bone and lipid metabolisms. The molecular mechanisms underlying the stagnation of meridians syndrome may be the imbalance of "immune-inflammation" and the blocking circulation. Furthermore, the liver and kidney deficiency syndrome may be not only associated with the abnormal bone and lipid metabolisms, but also implicated into various biological pathways-related to inflammation and circulation. Interestingly, the pharmacological mechanisms of the corresponding prescriptions may be in accord to the biological basis of each syndrome.
