Objective: To explore the psychological experience of patients with aortic dissection facing rescue of follow patients in CCU, so as to provide evidences for proposing appropriate nursing countermeasures and responding measures. Methods: A qualitative study was used on 16 patients with aortic dissection within 24 hours when the rescue of follow patients was in CCU through semi-structured in-depth interviews and the interview data were collected and analyzed by Colaizzi content analysis. Results: The enlargement of somatic discomfort symptoms. The various emotional. The different coping strategies. The inner needs. Conclusions When rescuing patients with other aortic dissection in CCU, medical staffs should pay more attention to the distress of physical discomfort symptoms such as pain, promote their benign mood during rescue and encourage patients to adopt positive coping styles. At the same time, constructing a reasonable social and family support ways to help patients recover physically and mentally, ensure the quality of nursing services and patient safety, and improve their hospitalization comfort.

BACKGROUND: Highly expressed in various human cancers, circular RNA Protein Kinase C Iota (circPRKCI) has been reported to play an important role in cancer development and progression. Herein, we sought to reveal the prognostic and clinical value of circPRKCI expression in diverse human cancers. METHODS: We searched the Pubmed, Web of Science, and the Cochrane Library databases from inception until May 16, 2021. The relationship between circPRKCI expression and cancer patients' survival, including overall survival (OS) and disease-free survival (DFS), was assessed by pooled hazard ratios (HR) with corresponding 95% confidence interval (CI). The correlation between circPRKCI expression and clinical outcomes was evaluated using odds ratios (OR) with corresponding 95% CI. The data were analyzed by STATA software (version 12.0) or Review Manager (RevMan 5.3). RESULTS: A total of 15 studies with 1109 patients were incorporated into our meta-analysis. The results demonstrated that high circPRKCI expression was significantly related to poor OS (HR = 1.96, 95% CI: 1.61, 2.39, P <0.001) when compared with low circPRKCI expression in diverse human cancers. However, elevated circPRKCI expression was not associated with DFS (HR = 1.34, 95% CI: 0.93, 1.95, P = 0.121). Furthermore, the patient with a higher circPRKCI expression was prone to have a larger tumor size, advanced clinical stage, and lymph node metastasis, but it was not significantly correlated with age, gender, and distant metastasis. CONCLUSION Elevated circPRKCI expression was correlated with worse OS and unfavorable clinical features, suggesting a novel prognostic and predictive role of circPRKCI in diverse human cancers.

OBJECTIVETo investigate the clinical characteristics, pathological classification and prognostic factors of gastrointestinal neuroendocrine neoplasms (GI-NENs).

METHODSClinicopathological data of 119 GI-NENs patients at Shanghai Renji Hospital from November 2007 to December 2016 were analyzed retrospectively. According to the classification and grading criteria of the WHO Neuroendocrine Tumor 2010 edition, patients were classified pathologically to realize the malignant degree of tumors. The overall survival rate was calculated by Kaplan-Meier curve, the prognostic risk factors were analyzed by Cox regression model, and the factors including the platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR) were included in the analysis in addition to the routine clinicopathological factors.

RESULTSOf 119 patients with GI-NENs, there were 83 cases (69.7%) of male and 36 cases (30.3%) of female. The age of patients ranged from 24 to 86 (median 61) years. Tumor locations included the stomach(n=70, 58.8%), duodenum(n=10, 8.4%), small intestine(n=2, 1.7%), appendix(n=3, 2.5%), colon(n=12, 10.1%), and rectum(n=22, 18.5%). The tumor diameter was 0.6 to 20 cm, the mean diameter was 5.4 cm, and the median diameter was 4 cm. There were 25 cases of G1 neuroendocrine tumor (NET), 7 cases of G2 NET and 87 cases of G3 neuroendocrine carcinoma (NEC). Among the 119 patients, 113 cases (95%) had complete follow-up, and the median follow-up was 75 (1 to 112) months. The 5-years overall survival rate was 58.4%. The survival rate of G1 NET, G2 NET and G3 NEC were 100%, 71.4%, 44.4%, and the difference was statistically significant (P=0.000). Univariate analysis showed that age ≥61 years (P=0.000), tumor located in the stomach, duodenum and colon (P=0.041), tumor size ≥4 cm (P=0.002), pathology classification of G3 NEC (P=0.000), late TNM staging (P=0.000) and blood PLR ≥133 (P=0.017) were associated with lower 5-year survival rate, but blood NLR level was not(P=0.263). Multivariate analysis showed that the patient age (HR=3.036, 95%CI: 1.548 to 5.956, P=0.001), the pathology classification(HR = 1.852, 95%CI:1.099 to 3.122, P=0.021), lymph node metastasis (HR=2.635, 95%CI:1.198 to 5.797, P=0.016) and distant metastasis (HR=2.685, 95%CI:1.383 to 5.214, P=0.004) were independent risk factors affecting the prognosis of patients, but the blood PLR level was not (HR=1.735, 95%CI: 0.947 to 3.176, P=0.074).

CONCLUSIONSThe malignant degree of GI-NEN is quite high, and the prognosis of patients is relatively poor. The age, pathological type and TNM staging are closely related to the prognosis of patients. Preoperative blood PLR may play a role in the prediction of prognosis, but preoperative blood NLR is not related with the prognosis of patients.

Objective: To investigate the significance of monitoring imatinib mesylate (IM) plasma concentrations in patients with gastrointestinal stromal tumor (GIST). Methods: A retrospective descriptive study was carried out. Inclusion criteria: (1) patients with GIST confirmed by postoperative pathology or puncture pathology receiving maintenance therapy of IM; (2) administration of same dose of IM for at least 4 weeks (achieving steady - state plasma concentration). Patients who had severe organ dysfunction, received IM generics, or received IM simultaneously with other drugs significantly affecting IM pharmacokinetic were excluded. A total of 185 patients at the GIST Clinic of Renji Hospital, Shanghai Jiaotong University School of Medicine from August 2018 to May 2019 were enrolled, including 114 males (61.6%) and 71 females (38.4%) with a median age of 60 years old (range, 30-89 years), and 63 advanced cases. Patients receiving preoperative or postoperative adjuvant therapy were given IM 400 mg QD; patients with KIT exon 9 mutation or with disease progression during IM 400 mg QD treatment were given IM 600 mg QD. If the patient had adverse reactions such as myelosuppression during the medication, IM would be reduced or given BID per day. The peripheral venous blood was collected (22 to 24 hours after the last dose for patients who took IM QD and 2 hours before the first dose per day for those who took IM BID). IM plasma concentration was measured through high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). Correlation analysis between IM plasma concentration results and clinical data was performed using linear regression analysis. Results: A total of 241 stable blood samples of IM plasma concentration from 185 patients were finally collected. The IM plasma concentrations were significantly different between the doses of 300 mg/d and 400 mg/d [(942.4±433.5) μg/L vs. (1340.0±500.1) μg/L, t=6.317, P<0.001], and between 400 mg/d and 600 mg/d [(1340.0±500.1) μg/L vs. (2188.0±875.5) μg/L, t=3.557, P=0.004]. Among the blood samples of 57 patients receiving IM 300 mg/d, the IM plasma concentration of the advanced patients was significantly lower than that of the non-advanced patients [(795.6±225.8) μg/L vs. (992.2±484.4) μg/L, t=2.088, P=0.042]. Among the 137 blood samples of patients receiving IM 400 mg/d, the IM plasma concentration was higher in patients aged >60 years than those aged ≤60 years [(1461.0±595.3) μg/L vs. (1240.0±380.9) μg/L, t=2.528, P=0.013] and the IM plasma concentration of cases with diarrhea was significantly lower than that of those without diarrhea [(745.8±249.6) μg/L vs. (1382.0±486.9) μg/L, t=6.794, P<0.001]. Gender, primary location, surgical procedure, mutated gene, mutation type, or time of administration was associated with IM plasma concentration no matter in patients taking IM doses of 400 mg/d or 300 mg/d (all P>0.05). Regression analysis showed that body mass (P=0.004 and P=0.019), body mass index (P=0.016 and P=0.042), and body surface area (P=0.007 and P=0.028) were all negatively correlated with IM plasma concentrations in patients taking IM doses of 300 mg/d and 400 mg/d. Within the 137 patients who received a fixed oral dose of 400 mg/d IM, 17 patients received oral 200 mg BID, whose IM plasma drug concentration was not significantly different compared with that of 120 patients who received 400 mg IM QD [(1488.0±408.3) μg/L vs. (1319.0±509.7) μg/L, t=1.307, P=0.193]. Conclusions Monitoring IM plasma concentration is significant throughout the whole process of management of GIST patients receiving IM treatment. In particular, regular monitoring IM plasma concentration and developing appropriate treatment strategies can bring better therapeutic benefits for patients with low doses, diarrhea, advanced condition and older age.
