OBJECTIVE:To improve high-alert medication management in our hospital. METHODS:According to assessment criteria of JCI,referring to the problems of high-alert medication management in our hospital,PDCA(plan,do,check,action)cy-cle method,reverse fishbone diagram and other methods were adopted to formulate and implement relevant countermeasures. Com-pliance rate of 29 departments was evaluated within 12 months after the implementation of countermeasures. RESULTS:Relevant emergency measures were formulated for 2 negative factors by reverse fishbone diagram;whole-course and orderly quality control of high-alert medication was conducted through establishing high-alert medication management institutions,formulating high-alert medication management system and quality measurement criteria,strengthening staff training and education,improving hospital in-formation system,etc. The compliance rate of departments increased from 53% in Jan. to 100% in Jun.(P<0.05),and kept sta-ble until Dec. CONCLUSIONS:PDCA cycle improves the systemization and standardization of high-alert medication management and multiple department cooperation,and contributes to the safety of drug use.

ObjectiveTo evaluate correlation factors of cervical lymph nodes metastasis in thoracic esophageal carcinoma.MethodsLocal-regional metastasis of lymph node for 126 cases with esophageal squamous cell cancer after surgery from 2004 to 2009 were reviewed.Risk factors of cervical lymph nodes metastasis were examined by multiple Logistic regression analysis.ResultsIn 126 cases,supraclavicular lymph node metastasis rate was 43.7％ (55/126).By logistic regression,none of the primary site,T stage,N stage,histological grade,lymph node metastasis rate,lymph node metastasis degree and number of lymph nodes metastatic field was not the high risk of cervical lymph nodes metastasis.In addition,multivariate analysis found that lymph node metastasis in mediastinum region 1 was high risk factor for lymph node metastasis of region 1 ( x2 =12.14,9.27,P =0.000,0.002),lymph node metastasis in region Ⅲ and region 2 were high risk factors for lymph node metastasis of region Ⅱa ( x2 =14.56,8.27,8.02,3.93,P =0.000,0.004,0.005,0.047 ).ConclusionMediastinal para-recurrent nerve lymph node metastasis is a significant predictor for cervical lymph nodes metastasis.

Objective:To evaluate the diagnostic value of serum prostate-specific antigen (PSA) levels and multi-parameter magnetic resonance imaging (mpMRI) in patients with granulomatous prostatitis after intravesical Bacillus Calmette-Guérin (BCG) therapy.Methods:The medical records of eight patients with pathologically proven granulomatous prostatitis in Shandong Provincial Hospital Affiliated to Shandong University from January, 2015 to June, 2020, were enrolled and analyzed in this retrospective study. All 8 patients (ages 47-76, mean 63.6) underwent pelvic mpMRI and serum tPSA levels before TURBT, which showed the results of tPSA, f/t and mpMRI were normal before TURBT (0.45-3.62 ng/ml, 0.20-0.51 and normal signal intensities on T1WI and T2WI, respectively). All patients underwent intravesical BCG therapy after post-TURBT 4-6-weeks’ intravesical gemcitabine therapy as a result of pathologically proven middle and high risk NMIBC via cystoscopy.Results:The results of tPSA levels in all 8 patients were elevated after intravesical BCG therapy after 9-15 months (mean 10.5 months), with 4 patients above 4 (6.77-12.89)ng/ml and 4 patients within the normal ranges(2.02-2.68)ng/ml, and f/t levels decreased to lower than 0.16 (0.09-0.15)in all patients. The mpMRI abnormal signals in all patients were all located in the peripheral zone of prostate. All nodular lesions of prostate mpMRI showed lower signal intensity (SI) on T2WI, higher SI on DWI and lower SI on ADC after BCG therapy. All patients underwent prostate biopsy for abnormal signal on prostate mpMRI. The biopsy pathologic results of all patients were granulomatous prostatitis.Conclusions:When elevated PSA and abnormal signals on prostate mpMRI after intravesical BCG therapy occurred, prostate biopsy may not be required for secondary granulomatous prostatitis patients with non-muscle invasive bladder cancer in combination of clinical history.

Gastric cancer is one of the most common malignant tumors worldwide, with its incidence and mortality rates ranking third among malignant tumors in China. Regulated cell death (RCD) is a type of cell death activated by signal transduction modules and closely connected to the progression and treatment of gastric cancer. Different types of RCD, comprising apoptosis, pyroptosis, ferroptosis, cuproptosis, and autophagy, not only aid in eliminating damaged cells, but also serve a crucial role in suppressing gastric cancer spread. This paper reviews different forms of RCD and their roles in the progression of gastric cancer, so as to provide reference for new diagnosis and treatment strategies of gastric cancer.
