Coronavirus Disease 2019 (COVID-19) is caused by 2019 novel coronavirus (2019-nCoV). Type I and type III interferons, as important available clinically used broad-spectrum antiviral drugs, have been considered as promising candidate drugs for the treatment and prevention of COVID-19. In early 2020, more than 40 clinical trials, including the World Health Organization (WHO) SOLIDARITY study, have been launched in the world to explore the clinical efficacy and application method of interferons in the treatment of COVID-19. Meanwhile, animal models and human clinical specimens were used in many laboratories to explore the immunologic role and mechanistic function of interferons in COVID-19. However, the conclusion of the studies in the past three years were not consistent and even contradictory albeit numerous data were accumulated by the scientific community, which reflects the complexity of the role and function of interferons in COVID-19. Recently, the results of four large high-quality randomized controlled phase III clinical trials were reported. In this review, we systematically summarize and analyze the complicated and contradictory data from the level of immunopathological mechanism and clinical trials. We clarify that the heterogeneous clinical outcome of 2019-nCoV infection is closely related to the level and production time of interferons and that interferons are protective in the early stage of COVID-19 but may cause immunological damages in the late stage which may exacerbate inflammation. Further high-quality prospective clinical trials that strictly control confounding factors are still warranted to finally elucidate the precise role and clinical application of interferons in COVID-19.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective:To sort out the development context of precision nursing and compare and analyze the advantages and shortcomings in this field at home and abroad, so as to provide reference for the development of precision nursing in China.Methods:Through Web of Science core collection and CNKI database, literature related to precision nursing at home and abroad from January 1, 2012 to December 31, 2022 was retrieved. CiteSpace software was used to draw a scientific knowledge map for visualization analysis.Results:A total of 509 literatures in Chinese and 1 037 literatures in English were detected, and the annual number of publications showed a significant upward trend since 2015. The high-yielding institutions were mostly located in the United States, and the distribution of domestic institutions was relatively dispersed. From the perspective of research hotspots and frontiers, foreign research focused on health promotion and disease prevention research oriented by biological information, while Chinese research focused on individualized nursing research oriented by patient needs.Conclusions:In recent 10 years, the research of precision nursing in China has developed rapidly, but relatively speaking, the depth and breadth of its research still need to be improved. Chinese research should learn from the experience of foreign precision nursing practice and explore the mode of precision nursing that conforms to national conditions in China.

Objective:To systematically review the risk prediction model for vaginal delivery failure in low-risk primiparas, so as to provide reference for clinical practice and future research.Methods:Literature on the risk prediction model for vaginal delivery failure in low-risk primiparas was retrieved from China National Knowledge Infrastructure, WanFang Data, China Biology Medicine disc, PubMed, Embase, Cochrane Library, CINAHL, Web of Science and so on. The search period was from the establishment of the database to September 20, 2023. Two researchers independently screened literature, extracted data, and evaluated the risk of bias in the included studies.Results:A total of 10 articles were included, involving 14 models. Twelve models were constructed using Logistic regression, and the area under the receiver operating characteristic curve of the models ranged from 0.680 to 0.847. Common predictive factors of the model involved age of pregnant woman, height of pregnant woman, pre-pregnancy body mass index, gestational weight gain, gestational week, fetal birth weight, induction method, fetal biological measurements, and pre-delivery cervical Bishop score.Conclusions:The predictive performance of the vaginal delivery failure risk prediction model for low-risk primiparas is good, but the model construction method is relatively simple, and the overall bias risk is high. The model needs to be further optimized through machine learning, artificial intelligence, and other means, and extensively validated externally.

OBJECTIVE To study the effects of Dianxianqing granules on the tau protein in P301S mice by regulating mitophagy. METHODS Totally 36 P301S mice were randomly divided into model group， Dianxianqing granule group （12.48 g/kg）， donepezil hydrochloride group （positive control， 1.3 mg/kg）， with 12 mice in each group； another 10 C57BL6 mice were selected as control group. Administration groups were given relevant drug solutions intragastrically， and control group and model group were given constant volume of water intragastrically. The gavage volume was 20 mL/kg， once a day， for consecutive 5 months. During the experiment， the general condition of mice was observed in each group. After the last medication， the learning and memory ability was determined by Y maze test and Morris water maze test； HE staining was used to observe the morphological changes in brain tissue， and Nissl staining was used to observe the structure of neural cells and the number of Nissl bodies in cerebral tissue. Immunohistochemistry was used to detect the expressions of phospho-tau serine 202/threonine 205 （abbreviated as AT8） in brain tissue. Western blot assay was used to determine the expressions of mitophagy-associated proteins [PTEN-induced putative kinase-1 （PINK1）， Parkin， microtubule-associated protein 1 light chain 3B （LC3B）， p62]， synaptic-associated proteins [postsynaptic density protein-95 （PSD-95）， synaptophysin （SYP）， and growth-associated protein-43 （GAP-43）] and the phosphorylation of tau protein [expressed by the phosphorylation levels of serine 199 （Ser199） and Ser202] in brain tissue. RESULTS The mice in E-mail：lnzyxyqy2003@163.com model group showed symptoms such as white hair， decreased body mass， and lower limb paralysis， with incomplete hippocampal structures in their brain tissue， as well as incomplete cell membrane edges and cell structures； the spontaneous alternating response rate， the times of crossing platform， the number of Nissl bodies， the protein expressions of PINK1， Parkin， LC3B， SYP， GAP-43， and PSD-95 were decreased significantly， compared with control group； swimming latency （fourth and fifth day）， the protein expressions of AT8 and p62，the phosphorylation levels of Ser199 and Ser202 were increased or lengthened significantly， compared with control group （P＜0.05 or P＜0.01）. Compared with model group， the above symptoms and indexes of mice were improved significantly in administration groups （P＜0.05 or P＜0.01）. CONCLUSIONS Dianxianqing granules can effectively improve cognitive impairment in P301S mice，the mechanism of which may be associated with inducing mitochondrial autophagy， reducing the hyperphosphorylation of tau protein， up-regulating the expression of synaptic-associated proteins in brain tissue，and repairing damaged neural cells.

The recovery rate of total radioactivity in urine and feces was calculated according to the weight and radioactivity concentration of urine and feces collected at each time interval. RESULTS: After a single 300 mg oral of radio-labeled CT-707 552 h (23 d) as a suspension in a fasted state, the mean AUC

Objective:To explore the effect of discharge preparation service strategy in hospital-community chronic disease management of patients with liver cirrhosis.Methods:From January 2018 to May 2019, the convenience sampling was used to select 162 patients with compensatory cirrhosis hospitalized in the Department of Infectious Diseases, Puyang People's Hospital of Henan Province. Patients were randomly divided into observation group and control group, with 81 cases in each group. Control group used routine management, and observation group carried out the discharge preparation service strategy. We compared the differences in re-admission rate and laboratory indicators between two groups after discharge.Results:Within 6 months after discharge, the re-admission rates of patients in observation group and control group were 4.94% (4/81) and 20.99% (17/81) respectively, and the difference was statistically significant (χ 2=9.246, P<0.05) . Six months after discharge, prealbumin of observation group was (226.48±27.52) mg/L higher than that of control group, and alanine aminotransferase of observation group was (90.26±6.72) U/L lower than that of control group, and differences were statistically significant ( t=5.482, -6.834; P<0.05) . Conclusions:Discharge preparation service strategy can reduce the re-admission rate of patients with liver cirrhosis and delay the progression of the disease, which is worthy of clinical application.

Hepatocellular carcinoma (HCC) is highly heterogeneous in nature and has been one of the most common cancer types worldwide. To ensure repeatability of identified gene expression patterns and comprehensively annotate the transcriptomes of HCC, we carefully curated 15 public HCC expression datasets that cover around 4000 clinical samples and developed the database HCCDB to serve as a one-stop online resource for exploring HCC gene expression with user-friendly interfaces. The global differential gene expression landscape of HCC was established by analyzing the consistently differentially expressed genes across multiple datasets. Moreover, a 4D metric was proposed to fully characterize the expression pattern of each gene by integrating data from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx). To facilitate a comprehensive understanding of gene expression patterns in HCC, HCCDB also provides links to third-party databases on drug, proteomics, and literatures, and graphically displays the results from computational analyses, including differential expression analysis, tissue-specific and tumor-specific expression analysis, survival analysis, and co-expression analysis. HCCDB is freely accessible at http://lifeome.net/database/hccdb.

Objective To investigate the effect of daily quality checklist on intensive care unit (ICU) the incidence of severe patients with hospital associated infection (HAI). Methods A historical control study was conducted. In Tianjin Fifth Center Hospital from June 2016 to May 2017, 286 severe patients with mechanical ventilation (MV) and using ICU daily quality checklist were assigned as the experimental group, and from June 2015 to May 2016, 291 severe patients who did not use the daily quality checklist were selected as the control group. In the control group, the routine treatment, nursing care and ward rounds were the daily ordinary work; in the experimental group, the severe disease ICU quality checklist system was strictly carried out, and every day the doctor and nurse on duty applied the checklist to assess and verify the medical quality given to the patient, including sedation, analgesia, MV, glycemic control, nutrition, etc 16 items. The incidences of ventilation associated pneumonia (VAP), catheter-related bloodstream infection (CRBSI), catheter-associated urinary tract infection (CAUTI), 28-day mortality, time of MV and the length of ICU stay were compared between the two groups. Results Compared with the control group, the incidences of VAP, CRBSI and CAUTI of experimental group were obviously decreased (VAP: 1.78‰ vs. 5.09‰, CRBSI: 1.46‰vs. 5.21‰; CAUTI: 1.39‰ vs. 4.41‰, all P ＜ 0.05), the time of MV and the length of ICU stay in experimental group were significantly shorter than those in the control group [the time of MV (days): 7.81±2.74 vs. 10.62±3.67, the length of ICU stay (days): 8.40±1.94 vs. 11.35±2.47, both P ＜ 0.05]; there was a decreasing tendency of 28-day mortality in experimental group compared with that in control group [5.24% (15/286) vs. 6.19% (18/291)], but no statistical significant difference was seen (P ＞ 0.05). Conclusion Implementation of daily quality checklist can effectively decrease the incidence of HAI in ICU patients, reduce the time of MV and the length of ICU stay.
