INTRODUCTION: Health literacy plays an essential role in one's ability to acquire and understand critical medical information in the coronavirus disease 2019 (COVID-19) infodemic and in other pandemics. We aimed to summarise the assessment, levels and determinants of pandemic-related health literacy and its associated clinical outcomes. METHODS: A systematic review was performed in Medline ® , Embase ® , PsycINFO ® , CINAHL ® and four major preprint servers. Observational and interventional studies that evaluated health literacy related to the novel COVID-19, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) were included. Items used in health literacy instruments were grouped under the themes of knowledge, attitudes and practices. Determinants of health literacy were grouped into five domains: sociodemographic, medical, psychological/psychiatric, health systems-related and others. RESULTS: Of the 2,065 articles screened, 70 articles were included. Of these, 21, 17 and 32 studies evaluated health literacy related to COVID-19, SARS and MERS, respectively. The rates of low pandemic health literacy ranged from 4.3% to 57.9% among medical-related populations and from 4.0% to 82.5% among nonmedical populations. Knowledge about the symptoms and transmission of infection, worry about infection, and practices related to mask usage and hand hygiene were most frequently evaluated. Sociodemographic determinants of health literacy were most frequently studied, among which higher education level, older age and female gender were found to be associated with better health literacy. No studies evaluated the outcomes associated with health literacy. CONCLUSION The level of pandemic-related health literacy is suboptimal. Healthcare administrators need to be aware of health literacy determinants when formulating policies in pandemics.

OBJECTIVE To observe the clinical efficacy of Yangyin Jiedu Decoction in the prevention and treatment of acute ra-diation-induced oral mucositis(RTOM).METHODS A total of 80 inpatients who were diagnosed with head and neck tumors by pathological examination and received radiotherapy in the Department of Radiotherapy,Affiliated Hospital of Nanjing University of Chi-nese Medicine from November 2021 to September 2023 were selected and randomly divided into an observation group and a control group with 40 cases in each group.The control group was given mouthwash treatment from the onset of RTOM symptoms until the symp-toms disappeared;the observation group was given Yangyin Jiedu Decoction from the first day of radiotherapy on the basis of the treat-ment of the control group until the end of radiotherapy.During the treatment,the onset time,duration and incidence of grade Ⅱ-ⅣRTOM in the two groups were observed;the pain numerical rating scale(NRS)score,Karnofsky performance status(KPS)score,body mass index(BMI)changes were evaluated;and the levels of serum inflammatory factors[C-reactive protein(CRP),interleukin 6(IL-6),interleukin 1β(IL-1β),tumor necrosis factor α(TNF-α)]were detected.RESULTS After radiotherapy,RTOM ap-peared in both groups to varying degrees.The incidence of grade Ⅱ-Ⅳ RTOM,the onset time,duration and NRS score of RTOM in the observation group were significantly better than those in the control group(P<0.05,P<0.01).After radiotherapy,the levels of se-rum CRP,IL-6,IL-1β and TNF-α in the observation group were lower than those in the control group(P<0.05,P<0.01).After radiotherapy and 1 month of follow-up,the KPS score and BMI in the observation group were higher than those in the control group(P<0.05,P<0.01).CONCLUSION Yangyin Jiedu Decoction can decrease the incidence and severity of RTOM in patients with head and neck tumors,shorten its duration,improve the quality of life of patients,downregulate the level of inflammatory cytokines,and has a preventive effect on RTOM caused by radiotherapy in patients with head and neck tumors.

Objective To investigate the effect of serum uric acid(SUA)on all-cause mortality and cardio-cerebrovascular diseases mortality in maintenance hemodialysis(MHD)patients.Methods Clinical data were retrospectively collected from MHD patients in Zhongshan Hospital,Fudan University from January 1,2015,to December 31,2016.The patients were categorized into low SUA group(SUA ≤ 399 μmol/L),medium SUA group(SUA 400-460 μmol/L),and high SUA group(SUA≥461 μmol/L)according to the tertiles of SUA level.The clinical data and laboratory examination results were compared among the three groups.The survival curves were plotted by Kaplan-Meier,and log-rank test were used to compare the survival rates among the three groups.Multivariate Cox regression was used to analyze the associations between SUA and all-cause mortality and cardio-cerebrovascular diseases mortality in MHD patients.Results A total of 436 MHD patients were enrolled,including 149 in low SUA group,144 in medium SUA group,and 143 in high SUA group.The median follow-up time was 59.7(38.4,60.9)months.During the follow-up,130 deaths were recorded,of which 90(69.2％)were due to cardio-cerebrovascular diseases.Kaplan-Meier survival analysis showed that the all-cause survival rate and cardio-cerebrovascular diseases survival rate of patients in low SUA group were lower than those in medium SUA group and high SUA group(P＜0.05).After adjusting for age,gender,comorbidities and other factors,the multivariate Cox regression analysis showed that the risk of all-cause mortality in patients decreased by 2.6％(HR=0.974,95％CI 0.952-0.996,P=0.022)and the risk of cardio-cerebrovascular diseases mortality decreased by 3.7％(HR=0.963,95％C1 0.937-0.991,P=0.008)for each 10 μmol/L increase in SUA level.The risks of all-cause mortality and cardio-cerebrovascular diseases mortality were significantly higher in low SUA group compared to high SUA group(HR=1.841,95％CI 1.138-2.979,P=0.013;HR=2.353,95％CI 1.288-4.300,P=0.005).Conclusions Low SUA level is independently associated with all-cause mortality and cardio-cerebrovascular diseases mortality in MHD patients.

OBJECTIVE: To compare the clinical efficacy on cervical spondylosis of nerve root type with qi stagnation and blood stasis treated with warming needle with different lengths of moxa stick. METHODS: Six hundred patients with cervical spondylosis of nerve root type with qi stagnation and blood stasis were randomly divided into 4 groups: a 4 cm length group (150 cases, 5 cases dropped off, 2 cases suspended), a 3 cm length group (150 cases, 6 cases dropped off, 2 cases suspended), a 2 cm length group (150 cases, 6 cases dropped off), and a routine acupuncture group (150 cases, 6 cases dropped off). Warming needle with moxa stick in the length of 4 cm, 3 cm and 2 cm was delivered in the 4 cm length group, the 3 cm length group and the 2 cm length group, respectively. In the routine acupuncture group, simple acupuncture was applied. The acupoints selected in the above groups included Dazhui (GV 14) and bilateral Jiaji (EX-B 2) of C₅ and C₇, Fengchi (GB 20), Jianzhen (SI 9), Quchi (LI 11), Zhongzhu (TE 3), etc. In each group, the intervention was delivered once daily and 5 times a week. One course of intervention was composed of 2 weeks and 2 courses were required. The TCM syndrome score, the score of clinical assessment scale for cervical spondylosis (CASCS), the score of the brachial plexus traction test of the affected upper limb, F wave occurrence rate and conduction velocity of the ulnar nerve, the median nerve and the radial nerve of the affected upper limb were compared before and after treatment in the patients of each group. The levels of serum inflammatory factors, i.e. interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor α (TNF-α) and hypersensitive C-reactive protein (hs-CRP), were measured before and after treatment in the patients of each group. The clinical cfficacy was evaluated in the 4 groups. RESULTS: After treatment, the results of TCM syndrome evaluation, i.e. the scores of neck pain, activity limitation and upper limb numbness and pain, as well as the total scores; and the scores of brachial plexus traction test were reduced when compared with those before treatment in each group (P<0.01, P<0.05). The scores of subjective symptoms and adaptability, and the total scores of CASCS were elevated in comparison with those before treatment in each group (P<0.01, P<0.05). In the 4 cm length group, compared with the other 3 groups, the scores of neck pain and activity limitation for TCM syndrome evaluation, and its total score were lower (P<0.05, P<0.01); and the scores of subjective symptoms and adaptability, and the total score of CASCS were higher (P<0.05, P<0.01). The score of the brachial plexus traction test in the 4 cm length group was lower than that of the routine acupuncture group (P<0.05). After treatment, F wave occurrence rates and conduction velocity of median nerve and radial nerve were increased when compared with those before treatment in each group (P<0.05, P<0.01). F wave occurrence rate and conduction velocity of the radial nerve in the 4 cm length group were higher than those of the other 3 groups (P<0.05), and those of the median nerve were higher when compared with the routine acupuncture group (P<0.05). After treatment, the levels of serum IL-1β, IL-6 and TNF-α were all reduced when compared with those before treatment in each group (P<0.01, P<0.05); the level of serum IL-6 in the 4 cm length group was lower than those of the other 3 groups and serum level of TNF-α was lower compared with that in the routine acupuncture group (P<0.05). The total effective rate of the 4 cm length group was 78.3% (112/143), which was higher when compared with the 3 cm length group (67.6%, 96/142), the 2 cm length group (65.3%, 94/144) and the routine acupuncture group (53.5%, 77/144), respectively (P<0.05). CONCLUSION Warming needle with moxa stick of 4 cm in length effectively relieves the clinical symptoms of cervical spondylosis of nerve root type with qi stagnation and blood stasis, improves the nerve function of the upper limbs, and reduces the inflammatory responses caused by nerve compression. The clinical efficacy of this therapy with moxa stick of 4 cm in length is superior to the warming needle with moxa sticks of 3 cm and 2 cm, as well as the routine acupuncture.

ObjectiveTo optimize the existing genetic transformation system of Armillaria gallica to improve the transformation efficiency and lay a foundation for the follow-up research on Armillaria molecular marker-assisted breeding and gene function. MethodThe genetically transformed plasmid pH101-PAgGPD-GFP-TrpC was constructed，transformed into Escherichia coli，amplified， and cultured，and the plasmid was extracted. The extracted plasmid was transformed into four different agrobacteria LBA4404，EHA105，GV3101，and AGL-1，respectively. The transformed agrobacteria were used for impregnating A. gallica，and the agrobacteria with the highest conversion rate were screened out. Then the agrobacterium-mediated genetic transformation system of A. gallica was optimized from the type and concentration of antibiotics，co-culture time，concentration of bacterial solution， and impregnation method. The phenotype profiles of A. gallica under different conditions were observed using Synbiosis ProtoCol 3. ResultThe optimized genetic transformation conditions of A. gallica were as follows： the Agrobacterium strain of EHA105 at absorbance A_{600 nm}=0.6， the co-culture time of 2 d， the infection mode of negative pressure impregnation for 10 min， the primary screening medium of PDA medium containing 400 mg·L^-1 cefotaxime sodium and 10 mg·L^-1 hygromycin，and the secondary screening medium of PDA medium containing 12 mg·L^-1 hygromycin. ConclusionIn this study，the existing genetic transformation system of A. gallica was optimized，and there was a significant difference in the transformation rate before and after optimization （P<0.05）. After optimization，the transformation efficiency of A. gallica was about 4.33%，which was about eight times higher than that before optimization.

Gut microbiota is a bridge between the metabolism and health state of the host,which plays a very important role in maintaining homeostasis. Natural polysaccharides,widely existed in nature,are a kind of biological macromolecules with prebiotics effects,which can improve a degree of physiological status by selectively changing the gut microbiota structure and function,enhancing the content of short chain fatty acids(SCFAs)and decreasing the level of inflammatory cytokines. In addition,the majority of polysaccharides can be degraded by gut microbiota to enhance their bioavailability and to promote the health state of the host. In this paper we discuss the interaction among polysaccharides and gut microbiotanatural,degradation mechanism and review gut microbiota as a target in the treatment of metabolic diseases,so as to provide future prospects of natural polysaccharides as " prebiotics " functional factors in the field of biological medicine and health products.

Objective: To summarize the preliminary experience in the treatment of esthesioneuroblastoma (ENB) and to explore the effect of age, chemotherapy, modified Kadish stage and pathological grade on the prognosis of ENB. Methods: The clinical data of 87 ENB patients from the First Affiliated Hospital of Sun Yat-sen University and Sun Yat-sen University Cancer Center between June 2002 and November 2017 were retrospectively analyzed. The modified Kadish stage was used to evaluate the extent of the lesions, and the Hyams grading system was used for pathological grading. The patients were followed up regularly to evaluate the recurrence and metastasis of the tumor. Cox proportional hazard model was used for univariate and multivariate analyses. Prognostic factors with P<0.05 in univariate analysis were included in multivariate analysis. After controlling the confounding factors, the model coefficients were used to calculate the hazard ratio (HR) and 95% confidence interval (CI). Results: The median follow-up time of ENB patients was 29 months, and the 5-year overall survival rate was 39.3%. In univariate analysis, age, chemotherapy, modified Kadish stage and pathology grade were independent predictors of overall survival, while gender, radiotherapy and surgery were not prognostic factors. Multivariate analysis showed that modified Kadish stage and pathology grade were independent predictors of overall survival rate after excluding confounding factors. Conclusions: Age, chemotherapy, modified Kadish stage and pathological grade are taking important role in the overall survival rate of patients with ENB. Modified Kadish stage and pathological grade are independent predictors of overall survival rate.

Background: Human infections with zoonotic coronaviruses (CoVs), including severe acute respiratory syndrome (SARS)-CoV and Middle East respiratory syndrome (MERS)-CoV, have raised great public health concern globally. Here, we report a novel bat-origin CoV causing severe and fatal pneumonia in humans. Methods: We collected clinical data and bronchoalveolar lavage (BAL) specimens from five patients with severe pneumonia from Jin Yin-tan Hospital, Wuhan, Hubei province, China. Nucleic acids of the BAL were extracted and subjected to next-generation sequencing. Virus isolation was carried out, and maximum-likelihood phylogenetic trees were constructed. Results: Five patients hospitalized from December 18 to December 29, 2019 presented with fever, cough, and dyspnea accompanied by complications of acute respiratory distress syndrome. Chest radiography revealed diffuse opacities and consolidation. One of these patients died. Sequence results revealed the presence of a previously unknown β-CoV strain in all five patients, with 99.8–99.9% nucleotide identities among the isolates. These isolates showed 79.0% nucleotide identity with the sequence of SARS-CoV (GenBank NC_004718) and 51.8% identity with the sequence of MERS-CoV (GenBank NC_019843). The virus is phylogenetically closest to a bat SARS-like CoV (SL-ZC45, GenBank MG772933) with 87.6–87.7% nucleotide identity, but is in a separate clade. Moreover, these viruses have a single intact open reading frame gene 8, as a further indicator of bat-origin CoVs. However, the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV, indicating that these viruses might use the same receptor. Conclusion: A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.
