OBJECTIVE To mine the adverse drug events （ADE） signals for gilteritinib， and provide a reference for safe drug use in clinic. METHODS ADE reports with gilteritinib as the primary suspected drug were extracted from the FDA Adverse Event Reporting System （FAERS） database from February 1st， 2018 to December 31st， 2023. Reporting odds ratio （ROR） and proportional reporting ratio （PRR） were applied to detect the risk signals from the data in the FAERS database. The classification and statistics of collected signal data were conducted by using the preferred term （PT） and systemic organ class （SOC） in ADE terminology set of the Medical Dictionary for Regulatory Activities （24.1 edition）. RESULTS Totally， 2 755 gilteritinib-related ADE reports were collected from the database， involving 676 ADE signals （95 positive signals）， 313 PTs and 25 SOCs. Among them， nine signals were not recorded in the package insert. The top 5 PTs consisted of abnormal liver function， decreased platelet count， febrile neutropenia， pneumonia and myelosuppression. The top 6 SOCs for positive signal counts were examinations， general disorders and administration site conditions， respiratory， thoracic and mediastinal disorders， infections and infestations， heart organ disorders， and nervous system disorders. ADEs not recorded in the drug package insert included pneumonia， myelosuppression， decreased blood cell count， sepsis， hemorrhage， infection （not specifically referred to）， septic shock， respiratory failure， and aspergillosis. CONCLUSIONS In addition to paying attention to common ADEs such as liver dysfunction and thrombocytopenia， it is necessary to monitor ADEs with strong signals that are not mentioned in the drug instructions when using gefitinib， such as pneumonia， bone marrow suppression， cytopenia， sepsis， bleeding， infection （not specifically referred to）， septic shock， respiratory failure， Aspergillus infection， elevated serum creatinine and interstitial lung disease.

Objective To understand the respiratory protection competency of staff in hospitals.Methods Staff from six hospitals of different levels and characteristics in Beijing were selected,including doctors,nurses,medical technicians,and servicers,to conduct knowledge assessment on respiratory protection competency.According to exposure risks of respiratory infectious diseases,based on actual cases and daily work scenarios,content of respira-tory protection competency assessment was designed from three aspects:identification of respiratory infectious di-seases,transmission routes and corresponding protection requirements,as well as correct selection and use of masks.The assessment included 6,6,and 8 knowledge points respectively,with 20 knowledge points in total,all of which were choice questions.For multiple-choice questions,full marks,partial marks,and no mark were given respective-ly if all options were correct,partial options were correct and without incorrect options,and partial options were correct but with incorrect options.Difficulty and discrimination analyses on question of each knowledge point was conducted based on classical test theory.Results The respiratory protection competency knowledge assessment for 326 staff members at different risk levels in 6 hospitals showed that concerning the 20 knowledge points,more than 60％participants got full marks for 6 points,while the proportion of full marks for other questions was relatively low.Less than 10％participants got full marks for the following 5 knowledge points:types of airborne diseases,types of droplet-borne diseases,conventional measures for the prevention and control of healthcare-associated infec-tion with respiratory infectious diseases,indications for wearing respirators,and indications for wearing medical protective masks.Among the 20 knowledge questions,5,1,and 14 questions were relatively easy,medium,and difficult,respectively;6,1,4,and 9 questions were with discrimination levels of ≥0.4,0.30-0.39,0.20-0.29,and ≤0.19,respectively.Conclusion There is still much room for hospital staff to improve their respiratory protection competency,especially in the recognition of diseases with different transmission routes and the indications for wearing different types of masks.

Objective To investigate the effects of Yuye Decoction(YYD)on diabetic nephropathy(DN)rats with Qi and Yin deficiency based on intestinal flora and intestinal mucosal barrier.Methods The content of the active ingredients puerarin,mangiferin and calycosin 7-O-β-D-glucopyranoside in YYD freeze dried powder was tested by HPLC to control the quality of YYD freeze dried powder.Forty-five Wistar rats were randomly divided into normal group(NC group),Qi-Yin deficiency DN group(M group)and YYD administration group(YYD group;5.03 g·kg-1)according to body weight.Intraperitoneal injections of streptozotocin(STZ)at a dose of 25 mg·kg-1 were administered,accompanied by oral gavage of adix Aconiti Lateralis,Citri Reticulatae Pericarpium Viride and Aurantii Fructus for 8 weeks to establish a Qi-Yin deficiency DN model in rats.During this period,rats in the YYD group were also treated with YYD extract.Weekly body weight and blood glucose levels were monitored for each group,along with observations of physical signs,food and water consumption,swimming time,and urine output in the rats.After 8 weeks,serum levels of cholesterol(TC),triglycerides(TG),low-density lipoprotein(LDL-C),high-density lipoprotein(HDL-C),serum creatinine(SCr)and urinary nitrogen(BUN)were analyzed in rats using automatic biochemical analysis.Hematoxylin-eosin staining(HE)was used to observe the pathological changes in the kidney and colon tissues.Enzyme-linked immunosorbent assay(ELISA)was used to measure urine protein concentration and serum levels of IgG,IgM,cAMP and cGMP.16SrDNA sequencing was used to sequence faecal flora and some flora were validated by quantitative real-time fluorescence PCR(qRT-PCR).Western blot method was used to measure the levels of intestinal barrier proteins and inflammatory factor proteins.Results The yield of YYD freeze-dried powder was 27.36%and the content of the active ingredients in YYD was 0.3496 mg·g-1 for puerarin,0.1851 mg·g-1 for mangiferin and 0.0429 mg·g-1 for calycosin 7-O-β-D-glucopyranoside.The results of animal experiments indicated that compared with Qi and Yin deficiency DN rats,YYD significantly improved the symptoms of lethargy and fatigue,increased swimming time,reduced water intake and increased food intake;increased the abundance of Bacteroidetes and decreased the abundance of Firmicutes in feces.Furthermore,according to measurements of blood lipids,blood glucose,renal function,IgG and IgM,as well as cAMP and cGMP,which are the energy homeostasis factors of the body,YYD could significantly improve the levels of these indicators in the model rats.HE staining showed that compared with model rats,YYD remarkably alleviated kidney and colon damage;inhibited the expression of inflammatory factors TNF-α and IL-6 in the kidney and colon,and markedly raised the expression levels of renal and colonic kinetic proteins CHRM3 and 5-HT3A as well as mucosal barrier proteins Occludin and ZO-1.Conclusion YYD play a role in preventing and treating in rats with Qi-Yin deficiency DN,and this effect may be related to YYD correcting intestinal flora dysbiosis,delaying intestinal mucosal damage and improving renal and colonic inflammation in the model rats.

Objective To explore the correlation between the expression of long non-coding RNA(lncRNA)brain ischemia-related factor(BIRF)and focally amplified lncRNA on chromosome 1(lncRNA FAL1)in serum and the degree of white matter lesions(WML)in patients with cerebral small vessel disease(CSVD).Methods From June 2021 to June 2023,102 CSVD patients admitted to Affiliated Hospital of Chengde Medical University were collected,and these patients were grouped into WML group(n=72)and non WML group(n=30)based on WML diagnostic criteria.According to the Fazekas score,the WML group was further grouped into mild WML group(n=24),moderate WML group(n=36)and severe WML group(n=12).Real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)was applied to detect the levels of lncRNA BIRF and lncRNA FAL1 in serum.Pearson correlation was applied to analyze the correlation between serum lncRNA BIRF and lncRNA FAL1 levels.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum lncRNA BIRF and lncRNA FAL1 levels for severe WML in CSVD patients.Results The age(70.50±5.86 years),history of hypertension(Yes/No,43/29),history of diabetes(Yes/No,45/27),IL-33(68.35±6.80 pg/ml),IL-18(97.78±9.65 ng/L),ubiquitin carboxyl terminal hydrolase L1(UCH-L1)(0.29±0.10 μg/L)and lncRNA BIRF level(2.45±0.30)of patients in the WML group were higher than those in the non WML group(67.10±5.76 years,11/19,9/21,62.48±6.13 pg/ml,92.56±9.37 ng/L,0.24±0.06 μg/L,1.02±0.11),while the expression of serum lncRNA FAL1(0.52±0.10)was lower than that in the non WML group(1.04±0.15),with significant differences(t=2.683,4.518,8.978,4.085,2.510,2.550,25.346,20.500,all P<0.05).The serum lncRNA BIRF levels of CSVD patients in the mild,moderate and severe WML groups(2.23±0.23,2.47±0.31,2.82±0.42)were increased sequentially,while the expression of serum lncRNA FAL1(0.60±0.15,0.51±0.09,0.40±0.04)was decreased sequentially,with significant differences(F=14.913,13.899,all P<0.05).Pearson correlation analysis,the serum levels of lncRNA BIRF and lncRNA FAL1 in patients with WML were negatively correlated(r=-0.603,P<0.001),serum lncRNA BIRF was positively correlated with Fazekas score in WML patients(r=0.483,P<0.001),but serum lncRNA FAL1 was negatively correlated with Fazekas score(r=-0.507,P<0.001).The AUCs of serum lncRNA BIRF and lncRNA FAL1 levels alone and both combination for predicting severe WML in CSVD patients were 0.756(0.641～0.850),0.839(0.733～0.915)and 0.892(0.796～0.953),respectively,and the combination of the two was superior to the detection of serum lncRNA BIRF alone(Z=2.111,P=0.035).Conclusion The serum lncRNA BIRF level is increased and lncRNA FAL1 is reduced in patients with CSVD and WML,and both are related to the degree of WML in CSVD patients.

Objective:To establish a nomogram for preoperative differentiating intrahepatic cholangiocarcinoma (ICC) from hepatocellular carcinoma (HCC) based on clinical, ultrasound, and contrast-enhanced ultrasound (CEUS) data.Methods:A retrospective analysis was conducted on ultrasound and CEUS data of 462 patients who underwent hepatectomy in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2016 to December 2023, including 262 cases of HCC (56.7%) and 200 cases of ICC (43.3%). The data were randomly divided into training set ( n=324) and validation set ( n=138) in a 7∶3 ratio. Univariate analysis was used to initially screen for variables with statistically significant differences between HCC and ICC groups in the training set, and LASSO regression was performed to select the variables with higher coefficients. Logistic regression analyses were then used to predict independent risk factors for ICC. A nomogram was drawn using R software. The performance of the nomogram was then validated using ROC curve, calibration curve, and decision curve analysis (DCA). Results:Univariate analysis showed that there were significant differences in age, gender, liver cirrhosis, HBsAg (+ ), ALP >185 U/L, CA19-9 >27 kU/L, CA242>10 kU/L, irregular shape, border, cholangiectasis, portal vein tumor thrombus, enhanced pattern in arterial phase, clearance time <60 s, intra-tumoral vein between ICC and HCC groups (all P<0.05). The top 10 features were selected for LASSO regression analysis. Logistic regression analysis revealed that gender, cirrhosis, CA19-9>27 kU/L, CA242>10 kU/L, cholangiectasis, clearance time <60 s, intra-tumoral vein and enhanced pattern in arterial phase were risk factors for ICC (all P<0.05). The area under the ROC curve in the training and validation groups were 0.963 and 0.914, respectively. In the training group, the specificity and sensitivity of the nomogram were 0.926 and 0.917, respectively, and in the validation group, they were 0.875 and 0.871, respectively. The calibration curve showed that the prediction effect of the model was in good agreement with the actual situation. DCA showed that the nomogram could increase the net benefit to the different diagnosis of ICC in patients. Conclusions:The nomogram based on clinical, ultrasound and CEUS features has a good predictive value for preoperative identification of ICC and provides reliable evidence for clinical practice.

Objective:To establish and evaluate a clinical and ultrasound parameters-based nomogram for the preoperative differentiating diagnosis of intrahepatic cholangiocarcinoma (ICC).Methods:A total of 723 patients undergoing hepatectomy in Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2016 to August 2022 were retrospectively screened. A total of 399 patients with hepatocellular carcinoma (HCC, 198 cases) or ICC (201 cases) were enrolled in this study, including 284 males and 115 females, aged (60.5±10.5) years. Through random sampling using computer-generated random numbers, patients were divided into training ( n=279) and validation groups ( n=120) in a ratio of 7∶3. Univariate and multivariate logistic regression were performed to identify factors differentiating ICC, and a nomogram was established using R software based on independent risk factors for ICC. The accuracy of the nomogram was evaluated by receiver operating characteristic curve and calibration curves. Decision curve analysis was performed to assess the net benefit of the model. Results:Multivariate logistic regression analysis showed that irregular shape, cholangiectasis, female, cirrhosis, carbohydrate antigen 242 >10 U/ml, carbohydrate antigen 125 >30 U/ml and alpha-fetoprotein >10 μg/L were independent differentiating factors for ICC (all P<0.05). A nomogram was constructed based on those factors. The nomogram showed a better discrimination between ICC and HCC. The area under the curve of the training group and the validation group were 0.966 and 0.956, respectively. The calibration curve showed that the prediction effect of the model is in good agreement with the actual situation. Decision curve analysis showed that the nomogram was more effective than diagnosing all patients as either HCC or ICC, which yielded a net benefit at the most reasonable threshold probabilities. Conclusion:The nomogram for the preoperative diagnosis of ICC based on clinical and ultrasound features showed a good diagnostic performance.

Objective To investigate the correlation between serum asprosin level and atrial fibrillation. Methods A total of 85 hospitalized patients with atrial fibrillation in the Department of Cardiology of Qingdao Municipal Hospital from October 2021 to October 2023 were selected as atrial fibrillation group, and 86 hospitalized patients with normal sinus rhythm in the same period were selected as non-atrial fibrillation group. Clinical materials and serum asprosin level of patients were collected and compared. Logistic regression analysis was performed to establish a linear stepwise regression model based on potential confounding factors for exploration in the independent risk factors for atrial fibrillation. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of asprosin for atrial fibrillation. Results Serum asprosin level in the atrial fibrillation group, was significantly higher than that in the non-atrial fibrillation group (P < 0.001). The linear stepwise regression model showed that asprosin was an independent risk factor for atrial fibrillation (OR=1.020, 95%CI, 1.005 to 1.036, P=0.01). The ROC curve showed that the area under the curve of serum asprosin in predicting atrial fibrillation was 0.745 (95%CI, 0.670 to 0.819). Conclusions Serum asprosin level is significantly elevated in patients with atrial fibrillation, and asprosin is an independent risk factor for atrial fibrillation. Serum asprosin level has good diagnostic value for atrial fibrillation.

We reported a case of a patient dignosed as tuberculosis and severe malnutrition with coronavirus disease 2019 （critical type） treated with a combination of Chinese medicine and Western medicine. Through the retrospective analysis of the diagnosis and treatment process of this patient， on the basis of Chinese medicine's understanding of the etiology and pathogenesis of “old state” and “deficient state”， the critical coronavirus pneumonia combined with pulmonary tuberculosis and severe malnutrition was mostly due to the physical condition and the invasion of epidemic toxin， resulting in dysfunctions of the internal organs such as the lungs， spleens， kidneys and other organs. Based on the understanding of the cause and mechanism of the coronavirus disease， the treatment combined Chinese and Western medical therapies was given. The western medicine was used with the main treatments of oxygen therapy， anti-viral， intestinal nutritional support， and anti-coagulation， while the Chinese medicine was used by tonifying qi， blood， yin， and yang， warming yang and dissipating cold， and clearing heat and dampness， then tonifying qi， nourishing yin and eliminating heat， in which tonifying middle and replenishing qi ran through the whole process. The integrated treatment eventually improved the patient's symptoms and accelerated the negative conversion of nucleic acid of the coronavirus.
