Objective:This study aims to simplify the Brief Patient Experience with Treatment and Self-Management (Brief PETS) by creating a Chinese version of the Brief PETS and evaluating its reliability and validity in a population of individuals with type 2 diabetes mellitus (T2DM).Methods:Following Mapi guidelines, the simplified Chinese version of the PETS scale was translated and culturally adapted. Simplified Chinese version of PETS and the Chinese version of the Treatment Burden Questionnaire (TBQ) were administered to T2DM patients recruited from community health centers in four regions of China between June and August 2022 by cluster sampling. Validity was assessed using content, construct, criterion-related, and discriminant validity, while reliability was evaluated using internal consistency and split-half reliability.Results:The Chinese short version of the PETS consists of 11 dimensions and 32 items, namely, medical information, medication, medical appointments, health management, medication side effects, diet, exercise, medical expenses, health care system, social roles, and physical and mental exhaustion. A total of 311 questionnaires were initially collected, with 289 valid responses finally analyzed after excluding ineligible surveys. The Cronbach′s α coefficient and the split-half reliability coefficient were 0.914 and 0.818 respectively. The content validity index (CVI) was 0.60-1.00, and S-CVI/Ave=0.84. Criterion validity showed that the total score of the Chinese simplified version of PETS was significantly correlated with the total score of TBQ ( r=0.804, P<0.01); discriminant validity was good ( P<0.01); nine male factors were extracted by exploratory factor analysis, which explained a total of 75.28% of the total variance, and each of the nine factors fitted different themes in the existing conceptual framework of the burden of care for T2DM with good construct validity. Conclusion:The Chinese version of the PETS scale demonstrates good reliability and validity, and can comprehensively explain the treatment burden of T2DM patients in primary healthcare settings in China.

Objective:To investigate the research competence and training needs of young general practitioners (GPs) in Guangdong province.Methods:A questionnaire survey on research competence and training needs was conducted in December 2020 among GPs from one selected economically developed area and one selected less developed area in Guangdong Province.Results:A total of 172 young GPs were included in the study. The survey showed that 75.6% (130/172) and 76.2% (131/172) respondents thought that participation in scientific research and research literacy were important, but only 11.9% (21/172) had participated in research project, among whom 81.0% (17/21) undertook data collection. The basic score of evidence-based medicine was 24.00(21.00, 28.00), and 55.2% respondents (95/172) were able search literature when they encountered problems and 43.7% (77/172) used domestic databases. The self-assessment score of scientific research ability was 14.00(12.00, 17.00), the score of research training needs was 41.00(31.00, 49.50), and the scores of "scientific research topic selection, scientific research design, statistical analysis, organization and implementation, and paper writing" were generally high. There was significant difference in the total scores of the two scales of evidence-based medicine basis and scientific research ability self-assessment among respondents with different educational background ( P<0.05). The basic score of evidence-based medicine of orientation-trained GPs was higher than that of non-orientation-tranined GPs; the average score of research training needs in female respondents was higher than that in males ( P<0.05). Conclusions:The study suggests that young general practitioners have inadequate experience in research participation and organization, and low self-ratings of research competence, but generally high personal efficacy in research. It is recommended that appropriate training content and well-organized intervention should be developed for young GPs.

PURPOSE: Developing a risk prediction model for invasive fungal disease based on an analysis of the disease-related risk factors in critically ill patients in the intensive care unit (ICU) to diagnose the invasive fungal disease in the early stages and determine the time of initiating early antifungal treatment. METHODS: Data were collected retrospectively from 141 critically ill adult patients with at least 4 days of general ICU stay at Sun Yat-sen Memorial Hospital, Sun Yat-sen University during the period from February 2015 to February 2016. Logistic regression was used to develop the risk prediction model. Discriminative power was evaluated by the area under the receiver operating characteristics (ROC) curve (AUC). RESULTS: Sequential organ failure assessment (SOFA) score, antibiotic treatment period, and positive culture of Candida albicans other than normally sterile sites are the three predictors of invasive fungal disease in critically ill patients in the ICU. The model performs well with an ROC-AUC of .73. CONCLUSION: The risk prediction model performs well to discriminate between critically ill patients with or without invasive fungal disease. Physicians could use this prediction model for early diagnosis of invasive fungal disease and determination of the time to start early antifungal treatment of critically ill patients in the ICU.

The main constituents of a typical medicinal herb,Polygonum muMflorum (Heshouwu in Chinese),that induces idiosyncratic liver injury remain unclear.Our previous work has shown that cotreatment with a nontoxic dose of lipopolysaccharide (LPS) and therapeutic dose of Heshouwu can induce liver injury in rats,whereas the solo treatment cannot induce observable injury.In the present work,using the constituent "knock-out" and "knock-in" strategy,we found that the ethyl acetate (EA) extract of Heshouwu displayed comparable idiosyncratic hepatotoxicity to the whole extract in LPS-treated rats.Results indicated a significant elevation of plasma alanine aminotransferase,aspartate aminotransferase,and liver histologic changes,whereas other separated fractions failed to induce liver injury.The mixture of EA extract with other separated fractions induced comparable idiosyncratic hepatotoxicity to the whole extract in LPS-treated rats.Chemical analysis further revealed that 2,3,5,4'-tetrahydroxy trans-stilbene-2-O-β-glucoside (trans-SG) and its cis-isomer were the two major compounds in EA extract.Furthermore,the isolated cis-,and not its trans-isomer,displayed comparable idiosyncratic hepatotoxicity to EA extract in LPS-treated rats.Higher contents of cis-SG were detected in Heshouwu liquor or preparations from actual liver intoxication patients associated with Heshouwu compared with general collected samples.In addition,plasma metabolomics analysis showed that cis-SG-disturbing enriched pathways remarkably differed from trans-SG ones in LPS-treated rats.All these results suggested that cis-SG was closely associated with the idiosyncratic hepatotoxicity of Heshouwu.Considering that the cis-trans isomerization of transSG was mediated by ultraviolet light or sunlight,our findings serve as reference for controlling photoisomerization in drug discovery and for the clinical use of Heshouwu and stilbene-related medications.

Objective To investigate the effect of precondition with Toll-like receptor 4 monoclonal antibody (TLR4mAb) on lipopolysaccharide (LPS) -induced acute lung injury in mice.Methods A total of 45 male BALB/c mice were randomly divided into 3 groups:the control group ( group C),the sepsis group (group S) and the pretreatment group (group P).Mice in the group P and group S were injected intraperitoneally with LPS ( 10 mg/kg) to produce acute lung injury models.Mice in the group P was injected intraperitoneally with TLR4mAb (5 μg/g) 1 h before the injection of LPS.Expression of TLR4mRNA in lung tissue,expression of TNF-α and IL-6 in serum,water content of lung,and the pathomorphologic changes of lung were detected after 6 h,12 h and 24 h.One-way ANOVA was used for inter-group comparison and two-way ANOVA was used for intra-group comparison.Results Compared to group C,water content significantly increased at 12 h and 24 h in group S and group P; compared to group S,water content significantly decreased in group P at 12 h and 24 h.Compared to group C,the expression of IL-6 and TNF-α significantly increased in group S and group P at 6 h,12 h and 24 h; compared to group S,the expression of IL-6 and TNF-α significantly decreased at 6 h,12 h and 24 h in group P.Compared to group C,the expression of TLR4 mRNA increased significantly in group S and group P at 6 h,12 h and 24 h; compared to group S,the expression of TLR4 mRNA decreased significantly in group P at6 h,12 h and 24 h.Compared to group S,pathological damage of the lung was improved significantly in group P.Conclusions Precondition with TLR4mAb can attenuate LPS-induced acute lung injury,suppress the expression of inflammatory factors.Regulation of TLR4 pathway may be a promising therapeutic strategy for ALI.
