Objective:To explore the adverse cardiac event risk signals in arsenical for injection, improve the clinical understanding of the cardiac toxicity of arsenical.Methods:The risk signals of adverse cardiac events associated with arsenical for injection were mined using 3 methods, including reporting odds ratio (ROR) method, proportional reporting ratio (PRR) method, and the Medicines and Healthcare Products Regulatory Agency (MHRA) comprehensive standard method based on data in Shandong Provincial Center of Adverse Drug Reaction Monitoring (Shandong data) in China from the first quarter of 2003 to the fourth quarter of 2022 and the data in US FDA Adverse Event Reporting System (FAERS) database from the fourth quarter of 2003 to the third quarter of 2023. The definition of risk signal in ROR and PRR method was the number of adverse event reports ≥3 and the lower limit of 95% confidence interval ( CI) of ROR and PRR >1. The definition of risk signals in MHRA comprehensive standard method was the number of adverse event reports ≥3, PRR>2, and χ2>4. Results:There were a total of 358 reports on arsenical for injection in Shandong data, of which 275 (76.8%) were related to arsenious acid and sodium chloride injection, and 83 (23.2%) were related to arsenic trioxide for injection. Among the 358 reports, adverse cardiac reactions were reported in 25 reports (7.0%), and severe cases accounted for 28.0% (7/25). There were a total of 1 294 reports on ATO in FAERS, and adverse cardiac events were reported in 418 reports (32.3%), of which severe cases accounted for 62.2% (260/418). The signal mining results form 275 reports on arsenious acid and sodium chloride injection in Shandong data showed that QT interval prolonged, chest tightness, cardiopalmus, and palpitations were risk signals. Among them, the signal strength of QT interval prolonged was the strongest. A total of 35 adverse cardiac event signals were mined in FAERS data, of which the signal strength of QT interval prolonged and long QT syndrome were the strongest. In addition, the strength of 6 arrhythmia signals (bradyarrhythmia, supraventricular premature contraction, ventricular premature contraction, torsade de pointes, ventricular tachycardia, and atrioventricular block) and 6 cardiac organic lesion signals (pericarditis, endocarditis, pericardial effusion, myocarditis, mitral regurgitation, and cardiac enlargement) also ranked high.Conclusions:Arsenical for injection is strongly associated with cardiotoxicity, and the proportion of severe cases is relatively high. The cardiotoxicity mainly affects the QT interval, and can also manifest as various types of arrhythmias and some cardiac organic lesions.

OBJECTIVE To analyze the dose-adjusted concentrations of Posaconazole oral suspension in patients undergoing hematopoietic stem cell transplantation （HSCT） and their influential factors. METHODS Data were collected from hospitalized HSCT patients admitted to the First Affiliated Hospital of Shandong First Medical University （Shandong Provincial Qianfoshan Hospital） from January 2021 to April whtwhm@yeah.net 2023 who took Posaconazole oral suspension for the prevention of invasive fungal disease （IFD） and received blood concentration of posaconazole. The rate of concentration attainment and clinical failure rate of posaconazole for the prevention of IFD were evaluated， and one-way and multiple linear regression analyses were performed for the influential factors of dose-adjusted concentrations （C0/D） of posaconazole. RESULTS A total of 44 patients were enrolled； the mean C0 of posaconazole in patients was （0.99±0.94） µg/mL， and 20 patients had a C0≥0.7 μg/mL， with a concentration attainment rate of 45.45% for the prevention of IFD； 13 cases were clinical failures， with a clinical failure rate of 29.55%. Of 24 patients who did not achieve C0/D of posaconazole for IFD prophylaxis， one patient was a clinical failure despite timely dose adjustment of posaconazole in seven patients； seven of the thirteen patients who did not undergo dose adjustment were clinical failures； and the remaining four patients were switched to other antifungal agents. The results of univariate analysis showed that gender， body mass index （BMI）， renal function， combined use of sodium phenytoin， omeprazole and metoclopramide had a significant effect on the C0/D of posaconazole （P＜0.05）； the results of multivariate linear regression analysis showed that gender， BMI and combined use of sodium phenytoin were the independent factors affecting the C0/D of posaconazole （P＜0.05）. CONCLUSIONS Significant individual differences are reflected in the blood concentration of Posaconazole oral suspension； gender， BMI and combined use of sodium phenytoin are independent factors affecting the C0/D of posaconazole.

OBJECTIVE To investigate the efficacy and safety of aerosol inhalation of polycolistin B in the treatment of severe pneumonia combined with mechanical ventilation， and to provide a reference of real-world data for clinical drug therapy. METHODS A retrospective cohort study was conducted to analyze the clinical data of 87 patients with severe pneumonia combined with mechanical ventilation at the First Affiliated Hospital of Shandong First Medical University from January 2021 to February 2023. According to route of administration， all patients were divided into combined group （24 cases， receiving aerosol YXH2021ZX013） inhibition of polycolistin B combined with intravenous dripping） and routine group （63 cases， intravenous dripping of polycolistin B alone）. The differences in efficacy （mortality，clinical response rate and bacterial clearance rate）and safety （elevated serum creatinine， bronchospasm and skin pigmentation） were compared between two groups； the influential factors of primary outcome index as mortality were analyzed through univariate analysis and multivariate Logistic regression analysis. RESULTS In terms of efficacy， there were no statistical differences in mortality（37.50% vs. 41.27%， P＝0.749）， clinical response rate （54.17% vs. 55.56%， P＝0.907） and bacterial clearance rate （45.83% vs. 44.44%， P＝0.907） between the two groups. In terms of safety， the incidence of bronchospasm in the combined group was significantly higher than that of the routine group （12.50% vs. 0， P＝0.028）， but the differences in incidence of elevated serum creatinine and skin pigmentation between two groups were not statistically significant （P＞0.05）. Univariate analysis showed that the moralities were higher in the case of infected with Acinetobacter baumannii， Klebsiella pneumoniae and combined use of quinolones （P＜0.05）； multivariate Logistic regression analysis showed that infection with A. baumannii （OR＝3.36， P＝0.014） and combined use of quinolones （OR＝3.54， P＝0.013） were independently associated with mortality （P＜0.05）. CONCLUSIONS For severe pneumonia patients with mechanical ventilation， intravenous dripping of polycolistin B combined with aerosol inhalation does not show superior efficacy compared with intravenous dipping of polycolistin B alone， but significantly increases the incidence of bronchospasm. Infection with A. baumannii and combined use of quinolones are independent risk factors for the increase of mortality.

The theoretical basis was provided for the further development and utilization of the iridoids in Morinda genus.

Objective To observe the efficacy of mesalazine combined with probiotics in the treatment of ulcerative colitis. Methods 60 patients with ulcerative colitis who were admitted to our hospital from May 2015 to May 2017 were selected randomly. These patients were divided into two groups according to the treatment method: mesalamine com bined with probiotic group(combination therapy group, n=30) and mesalamine alone treatment group (n=30). The clinical symptom score, endoscopic score, serum CRPlevel, clinical efficacy, incidence of adverse reactions and recurrence in both groups were statistically analyzed. Results Compared with those before treatment, the clinical symptom score, en doscopic score and serum CRPlevel were significantly lower in both groups after treatment(P＜0. 05); After treatment, clinical symptom score, endoscopic score and serum CRPlevel were significantly lower in the combination therapy group than those in the treatment alone group(P＜0. 05). The total effective rate in the combination therapy group was 93. 3％(28/30), significantly higher than 63. 3％(19/30) in the treatment alone group(P＜0. 05). The recurrence rate was 13. 3％ (4/30), significantly lower than that of 33. 3％(10/30) in the treatment alone group(P＜0. 05). However, the incidence rates of adverse reactions in the two groups was 6. 7％(2/30) and 10. 0％(3/30) respectively, which were not significantly different(P＞0. 05). Conclusion The efficacy of mesalazine combined with probiotics in the treatment of ulcerative colitis is more significant than that of mesalazine alone. At the same time, it is also more effective in improving the clinical symptoms, reducing the serum CRPlevel and recurrence rate in the patients, and will not increase the patients' adverse reactions to a great extent, so it is worthy of promotion and application in clinical settings.

OBJECTIVE: To investigate the significance and relationship between the expression of FOXC1 and clinicopathological features, and to explore its correlation with E-cadherin. METHOD: Immunohistochemical SP method was used to detected the expression of FOXC1 in nasopharyngeal carcinoma tissues and nasopharyngitis tissues. RESULT: (1) Immunoreaction to FOXC1 was mainly located in nucleus of nasopharyngeal carcinoma cells. The positive expression rate of FOXC1 in nasopharyngeal carcinoma tissues was 85.3% (81/95), which was significantly higher than that in nasopharyngitis tissues (59.4%) (P < 0.05). (2) The expression of FOXC1 was not related to patients' age and gender, clinical stage of cancer and lymph node metastasis (P > 0.05). (3) There was a correlation between the expression of FOXC1 and down-regulated expression of E-cadherin in nasopharyngeal carcinoma tissues (P < 0.05). CONCLUSION FOXC1 may play an important role in generation and progression of nasopharyngeal carcinoma, there may be a correlation between the expression of FOXC1 and down-regulated expression of E-cadherin, also FOXC1 may play an important role in the process of EMT in nasopharyngeal carcinoma by regulating E-cadherin.
