Objective:To explore the barriers and facilitators for family members to inform elderly cancer patients of their condition.Methods:From August 2020 to September 2021, a total of family members of 16 elderly cancer patients admitted to the Renmin Hospital of Wuhan University were selected by convenient sampling. Semi-structured qualitative interview was conducted with the patients' family members. Colaizzi 7-step analysis method was used to analyze, sort out and refine the data.Results:A total of 8 themes were extracted. Barriers included integrating the patient's personality and experience to speculate the patient's acceptance, it was predicted that the sadness would be aggravated after being informed according to the current condition, lack of support and communication barriers. Facilitators included conjecture based on the patient's personality and willingness, there was a need to know the condition, maintaining family atmosphere and family culture and reference to relevant external information.Conclusions:There are many barriers and facilitators in the condition notification of elderly cancer patients. Medical and nursing staff and family members should not blindly conceal patients' condition. We should pay attention to patients' expression and respect their wishes, and provide personalized information and care strategies based on their past experience and current situation.

OBJECTIVETo describe the incidence and related risk factors of fatty liver disease in the general population of Northwest China.
METHODSThe study was a cross-sectional survey with multiplestage stratified cluster and random sampling. All participants were 18 years or older and resided in northwest provinces of China.Demographic and behavioral data was gathered by questionnaire.Clinical data such as height, body weight, waist circumference, biochemical function (standard tests) and liver status (ultrasonographic examination) were also collected.
RESULTSAmong the 2 300 total study participants, 1 523 were habitual drinkers (total drinking rate: 66.2%). This population of drinkers was composed almost exclusively of males. There were 201 cases of alcoholic liver disease (total prevalence:8.7%), represented by mild alcoholic injury (prevalence: 4.2%), alcoholic fatty liver (3.8%), alcoholic hepatitis (0.5%), and alcoholic cirrhosis (0.3%).When examined according to provinces of residence, the prevalence of alcoholic liver disease followed this pattern: Shaanxi (14.0%), Gansu (8.6%), and Xinjiang autonomous region (5.0%). Of the total 337 cases of nonalcoholic fatty liver disease (total prevalence: 14.7%), the prevalence by province was: Shaanxi (18.5%), Gansu (10.3%), and Xinjiang autonomous region (16.6%). Individuals with alcoholic liver disease had significantly higher mean age (years), body weight, body mass index (BMI), waist circumference, average daily alcohol intake, and level of aspartate aminotransferase (AST), and alanine aminotraasferase (ALT) (vs. Those with no liver disease, P less than 0.05). Individuals with nonalcoholic fatty liver disease had significantly higher mean age (years), height, body weight, BMI, waist circumference, level of AST and ALT, and presence of obesity, abdominal obesity, hyperlipidemia, diabetes mellitus and hypertension (vs. Those with no liver disease, P less than 0.05). Multiple logistic regression demonstrated that alcoholic liver disease was closely related to age, sex, and average daily alcohol intake. The prevalence of nonalcoholic fatty liver disease was positively correlated to age, female sex, hyperlipidemia, diabetes mellitus, and BMI.
CONCLUSIONThe drinking-rate and prevalence of fatty liver disease is high in Northwest China, but the most prevalent type is nonalcoholic fatty liver disease.Fatty liver disease is closely related to age, sex, average daily alcohol intake, hyperlipidemia, diabetes mellitus, and BMI.

Tertiary lymphoid structures (TLS) are ectopic lymphoid structures in cancers that are largely associated with favourable prognosis. However, the prognostic value of TLSs in oral squamous cell carcinoma (OSCC) is largely unknown, and the association between tumour infiltrating lymphocytes (TILs) and TLSs has been rarely explored in OSCC. In this study, associated markers of TLS, including peripheral node address (PNAd) in high endothelial venules, CD20 in B cells and CD3 in T cells, were examined in 168 OSCC patients, and survival analysis was performed between TLS-positive and TLS-negative cohorts. We detected the presence of TILs by staining CD8+ cytotoxic T cells and CD57+ NK cells as well. TLSs appeared as highly organized structures in 45 (26.8%) cases. TLS-positive patients had a better 5-year overall survival (OS) rate (88.9% vs. 56.1%, P < 0.001) and relapse-free survival (RFS) rate (88.9% vs. 63.4%, P = 0.002). Moreover, the presence of TLS was an independent prognostic factor for both the 5-year OS rate (hazard ratio [HR] = 3.784; 95% confidence interval [CI], 1.498-9.562) and RFS rate (HR = 3.296; 95% CI, 1.279-8.490) in multivariate analysis. Furthermore, a higher density of CD8+ T cells and CD57+ NK cells was found in TLS-positive sections than in TLS-negative counterparts (P < 0.001), and their combination provided a higher predictive accuracy (AUC = 0.730; 95% CI, 0.654-0.805). In conclusion, our results suggest that TLS is an independent positive prognostic factor for OSCC patients. These findings provide a theoretical basis for the future diagnostic and therapeutic value of TLSs in OSCC treatment.

Existing traditional Chinese medicine (TCM)-related databases are still insufficient in data standardization, integrity and precision, and need to be updated urgently. Herein, an Encyclopedia of Traditional Chinese Medicine version 2.0 (ETCM v2.0, http://www.tcmip.cn/ETCM2/front/#/) was constructed as the latest curated database hosting 48,442 TCM formulas recorded by ancient Chinese medical books, 9872 Chinese patent drugs, 2079 Chinese medicinal materials and 38,298 ingredients. To facilitate the mechanistic research and new drug discovery, we improved the target identification method based on a two-dimensional ligand similarity search module, which provides the confirmed and/or potential targets of each ingredient, as well as their binding activities. Importantly, five TCM formulas/Chinese patent drugs/herbs/ingredients with the highest Jaccard similarity scores to the submitted drugs are offered in ETCM v2.0, which may be of significance to identify prescriptions/herbs/ingredients with similar clinical efficacy, to summarize the rules of prescription use, and to find alternative drugs for endangered Chinese medicinal materials. Moreover, ETCM v2.0 provides an enhanced JavaScript-based network visualization tool for creating, modifying and exploring multi-scale biological networks. ETCM v2.0 may be a major data warehouse for the quality marker identification of TCMs, the TCM-derived drug discovery and repurposing, and the pharmacological mechanism investigation of TCMs against various human diseases.
