RESUMEN
Objective To investigate the effectiveness of 4M1E refined management method in reducing dispensing time of outpatient prescription in outpatient pharmacies under the implementation of a long-term prescription policy.Methods The hospital started to implement 4M1E refinement management in July 2022.Ten thousand prescriptions were randomly selected for each of the pre-implementation(from January to June 2022)and post-implementation(from July to December 2022)human-machine hybrid dispensing windows.The dispensing time of a single prescription,the volume of prescriptions dispensed and the number of drugs prescribed during peak periods,the use of intelligent equipment,and patient satisfaction before and after imple-mentation were compared.Results After implementation,the single prescription drug dispensing time at the mixed human-ma-chine dispensing window was reduced from(96.88±1 401.17)s to(55.84±526.24)s(P<0.01);The number of prescriptions dispensed in the window increased from(135.20±21.06)to(147.19±21.24)prescriptions per 2 h,and the number of drugs pre-scribed increased from(871.74±215.61)to(1 008.53±267.87)prescriptions per 2 h during peak hours.The rate of straight prescription and the rate of equipment automation have been greatly improved.Outpatient satisfaction was higher than before man-agement.The data showed statistical differences(P<0.05).Conclusion Under long-term prescription pressure,hospital outpa-tient pharmacies can greatly reduce prescription dispensing time and improve patient satisfaction after applying the 4M1E fine management method.
RESUMEN
Objective:To evaluate the diagnostic performance of radiomics model based on contrast-enhanced ultrasound(CEUS) in predicting pathological complete response(pCR) after neoadjuvant chemoradiotherapy(nCRT) in patients with locally advanced rectal cancer(LARC).Methods:One hundred and six patients with LARC who underwent total mesorectal excision after nCRT between April 2018 and April 2023 in the First Affiliated Hospital of Guangxi Medical University were retrospectively included, the patients were randomly divided into a training set of 63(14 pCR patients) and a validation set of 43(12 pCR patients) in a 6∶4 ratios. Radiomics features were extracted from the tumors′ region of interest of CEUS images based on PyRadiomics. Intra-class correlation coefficient(ICC), Mann-Whitney U test, and least absolute shrinkage and selection operator(LASSO) algorithms were used to reduce features dimension. Finally, 7 radiomics features relevanted to pCR were selected to construct an ultrasomics model using elastic network regression, based on the R language. A combined model was constructed by jointing clinical feature. The performance of the models was assessed with the area under the ROC curve(AUC). Results:The AUC of the ultrasomics model and the combined model was 0.695(95% CI=0.532-0.859) and 0.726(95% CI=0.584-0.868) respectively in the training set. The AUC of the ultrasomics model and the combined model was 0.763(95% CI=0.625-0.902) and 0.790(95% CI=0.653-0.928) respectively in the validation set. Both univariate and multivariate Logistic regression analyses showed that CA199( P<0.05) and ultrasomics score( P<0.001) could be an independent predictor of pCR after nCRT in patients with LARC. Conclusions:The CEUS-based radiomics scores has certain predictive value for whether LARC patients achieve pCR after nCRT, and may provide a non-invasive imaging biomarker for predicting LARC patients achieve pCR after nCRT.
RESUMEN
Aim To explore the differential expression genes (DEGs) and potential therapeutic drugs of neutrophilic asthma (NA) based on bioinformatics analysis and molecular docking. Methods The gene expression profiles of NA were obtained from GEO database, and the differential expression genes were screened. The protein-protein interactions (PPI) of DEGs were obtained from STRING database, and the hub genes were screened by Cytoscape according to the degree of DEGs. The GO and KEGG pathway analysis were performed by DAVID database. Finally, molecular docking technology was used to screen the potential therapeutic drugs for the treatment of NA. Results A total of 147 DEGs were obtained from NA patients compared with healthy people in GEO database. Ten hub genes were screened from PPI network, including CXCL8, FPR2, CXCL1, TNFRSF1B, CXCR1, etc. Go enrichment analysis showed that DEGs were mostly associated with inflammation, immune response and chemotaxis, etc. KEGG pathway analysis indicated that the DEGs were mainly involved in cytokine-cytokine receptor interaction and complement and coagulation signaling pathways. Molecular docking showed that paeoniflorigenone and triptolide had good binding activity with C8B and PLAU. Conclusion Complement and coagulation cascades may become a new therapeutic target of NA. The two screened compounds paeoniflorigenone and triptolide may be potential therapeutic drugs for the treatment of NA.
RESUMEN
Objective@#To investigate the effect of tumor deposits (TD) on the prognosis of patients with stage III colon cancer, and to explore whether TD number included into regional lymph node count can predict the prognosis more accurately.@*Methods@#A retrospective cohort study was carried out. Case inclusion criteria: (1) primary colon cancer; (2) undergoing colon cancer radical operation; (3) definite pathological diagnosis; (4) colon cancer stage III according to AJCC 8th edition; (5) complete follow-up data; (6) without preoperative neoadjuvant treatment. Clinicopathological data of 296 patients undergoing colon cancer radical operation from January 2005 to December 2008 in the Cancer Hospital of Chinese Academy of Medical Sciences were retrospectively collected. The effect of TD and its amount on the prognosis was evaluated. Colon cancer TNM staging method based on the 8th edition of AJCC was compared with the modified TNM staging (mTNM) adjusted by the number of TD. The differences of the disease-free survival (DFS) and overall survival (OS) between groups were also examined. The Kaplan-Meier curve was used to analyze the survival, and prognostic factors were analyzed by Cox univariate and multivariate analyses.@*Results@#Among 296 patients with stage III colon cancer, 78 patients had TD. The median number of TD was 2 (1-10). Tumor T stage, N stage, vascular tumor thrombus and preoperative carcinoembryonic antigen (CEA) were associated with TD in patients with colon cancer (all P<0.05). The right hemicolon appears likely to have TD than left hemicolon, but the difference was not statistically significant (P=0.059). The median follow-up of the whole group was 71 (6-102) months. During the follow-up period, 129 patients (43.6%) had recurrence or metastasis, and 111 patients died (37.5%). The 5-year DFS in TD group was 44.9%, which was lower than that in the non-TD group (60.6%), with statistically significant difference (P=0.003). The 5-year OS in TD group was 50.0%, which was also lower than 67.0% in the non-TD group, and the difference was statistically significant (P=0.002). According to TD number, patients were divided into 3 groups: 1 TD (25 cases), 2-3 TD (32 cases), ≥4 TD (21 cases). The 5-year DFS in these 3 groups was 68%, 56.3%, and 0, respectively (P<0.001), and 5-year OS was 76%, 59.4%, and 4.8% respectively (P<0.001). Univariate analysis showed that TD presence (95% CI: 1.234-2.694, P=0.003) and TD number (95% CI: 3.531-14.138, P<0.001) were associated with the prognosis of patients with stage III colon cancer. At the same time, age, tumor N stage, tumor location, chemotherapy, and preoperative CEA elevation were also associated with the prognosis of stage III colon cancer patients (all P<0.05). Multivariate analysis revealed that TD presence (HR=1.957, 95%CI: 1.269-3.017, P=0.002) and TD number (HR=8.020, 95% CI: 3.414-18.842, P<0.001) were still independent risk factors for the prognosis of patients with stage III colon cancer.According to the TD number counted as metastatic lymph nodes, in 78 patients with TD, 24 patients were upstaged in N stage, and 16 patients upstaged from TNM stage IIIB to stage IIIC. For 16 stage IIIB cases with staging modification, 30 unadjusted stage IIIB cases with TD, and 148 stage IIIB cases without TD, the 5-year OS was 37.5%, 73.3% and 76.4%, respectively with significant difference (P<0.001). However, for 16 patients adjusted as stage IIIC (mTNM), 32 patients with unchanged stage IIIC with TD (TNM, AJCC 8th edition), and 63 stage IIIC cases without TD, the 5-year OS was 37.5%, 36.4%, and 41.3%, respectively without significant difference (P=0.707).@*Conclusions@#TD presence and TD number are independent risk factors for prognosis of stage III colon cancerpatients. TNM staging evaluation with lymph node number including TD number can predict the prognosis of patients more accurately.

<p><b>OBJECTIVE</b>To explore the relationship between DNA mismatch repair (MMR) and clinicopathologic features and prognosis in patients with stages II and III colon cancers.</p><p><b>METHODS</b>The clinical and pathological data of 440 patients with stage II/III colon cancer after radical resection were retrospectively reviewed and analyzed. Immunohistochemical staining was used to assess the expression of MMR proteins (MLH1, MSH2, MSH6 and PMS2), and the correlation between DNA MMR and clinicopathological features and prognosis of colon cancers was analyzed.</p><p><b>RESULTS</b>Of the 440 tumor samples tested for DNA mismatch repair status, 90 (20.5%) demonstrated defective DNA mismatch repair and 350 (79.5%) had proficient DNA mismatch repair. Defective DNA mismatch repair (dMMR) was associated with young patients (≤ 60), proximal colon cancer, stage II, poorly differentiated adenocarcinoma and mucinous adenocarcinoma (P<0.05 for all). Among the 440 patients, 126 (28.6%) cases had recurrence or metastasis and 93 (21.1%) died during the median follow-up of 61.0 months. The five-year disease-free survival (DFS) rate was 82.2% among the patients with tumor exhibiting dMMR, significantly higher than that in patients with tumors exhibiting pMMR (68.9%, P=0.02). The univariate and mutlivariate analyses showed that the MMR status is an independent factor affecting 5-year disease-free survival and overall survival (OS) in colon cancer patients (P<0.05 for both).</p><p><b>CONCLUSIONS</b>Defective DNA mismatch repair (dMMR) is associated with patients with proximal colon cancer, stage II and poorly defferentiated adenocarcinoma and mucinous adenocarcinoma.

<p><b>OBJECTIVE</b>To investigate the role of DNA mismatch repair (MMR) as a prognostic indicator of radical resection and a predictor of fluorouracil-based adjuvant therapy benefit in patients with stage II/III colon cancer.</p><p><b>METHODS</b>The clinicopathological characteristics of 172 patients with stage II/III colon cancer who underwent radical resection were retrospectively analyzed. Immunohistochemical staining was used to detect the expression of DNA mismatch repair (MLH1/MSH2/MSH6/PMS2) in the tumor tissues.</p><p><b>RESULTS</b>Among a total of 172 patients, there were 38 (22.1%) cases with defective DNA mismatch repair (dMMR) and 134 (77.9%) cases with proficient DNA mismatch repair (pMMR). Among the 115 patients who did not receive adjuvant chemotherapy, those with tumor displaying dMMR had a better 5-year overall survival (OS) rate and disease-free survival (DFS) rate than the patients with proficient DNA mismatch repair (pMMR) (88.0% vs. 66.7%, P = 0.040; 84.0% vs. 60.0%, P = 0.034). The benefit of adjuvant chemotherapy differed significantly according to the MMR status. Adjuvant 5-Fu chemotherapy improved the 5-year overall survival rate among 134 patients with pMMR (86.4%) than that in patients treated by surgery alone (66.7%, P = 0.012). By contrast, there was no benefit of adjuvant 5-Fu chemotherapy in the patients with dMMR (61.5% vs. 86.4%, P = 0.062), which was even more clear the 5-year disease-free survival rate (53.8% vs. 84.0%, P = 0.038).</p><p><b>CONCLUSIONS</b>MMR status is a predictor of the benefit of adjuvant chemotherapy with fluorouracil in stage II/III colon cancer. Patients with stage II/III colon cancer displaying dMMR have a better prognosis than those with pMMR.</p>

PURPOSE: Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an inflammatory enzyme expressed in atherosclerotic plaques. We investigated the association of circulating Lp-PLA2 with characteristics of vulnerable coronary atherosclerotic plaques. MATERIALS AND METHODS: We recruited 113 patients with either unstable angina (UA, n=59) and stable angina (SA, n=54) by coronary angiography. Thirty-six healthy subjects served as controls. Intravascular ultrasound (IVUS) was used to evaluate the characteristics of coronary atherosclerotic plaque, and serum Lp-PLA2 concentration was measured as well. RESULTS: Lp-PLA2 concentration was significantly higher in both UA and SA patients [(396+/-36) microg/L and (321+/-39) microg/L, respectively] compared with the controls [(127+/-49) microg/L, p<0.01], and higher in UA than SA group. IVUS findings showed that remodeling index (RI) (0.91+/-0.15 vs. 0.85+/-0.11, p=0.005) and eccentricity index (EI) (0.73+/-0.16 vs. 0.65+/-0.22, p=0.039) were larger in UA than in SA group, and fibrous caps were thicker in SA than UA group [(0.91+/-0.23) mm vs. (0.63+/-0.21) mm, p=0.032]. Moreover, Lp-PLA2 correlated positively with EI (r=0.439, p<0.01) and RI (r=0.592, p<0.05) in UA group. There was an inverse relationship between Lp-PLA2 and fibrous cap thickness in both UA (r=-0.587, p<0.001) and SA (r=-0.318, p<0.05) groups. The independent risk factors in UA group were Lp-PLA2 (OR=1.055, 95% CI: 1.03-1.08, p=0.013), LDL-cholesterol (OR=0.032, 95% CI: 0.00-0.05, p=0.041) and fibrous cap thickness (OR=0.008, 95% CI: 0.00-0.45, p=0.019). Lp-PLA2 was strongly associated with both EI and fibrous cap thickness in both groups. CONCLUSION: Serum level of Lp-PLA2 is associated with both eccentricity index and fibrous cap thickness in both UA and SA groups. Elevated levels of circulating Lp-PLA2 might to be a strong risk factor and more serious for unstable angina than stable angina.
