Aim: To establish a linear additive model for the predication of in vitro sinomenine hydrochloride release from the combination of immediate release, enteric-coated and sustained-release pellets based on the release profiles of each pellet type. Methods: Immediate release pellets were manufactured by extrusion/spher-onization technology. The operation of bottom-spraying in the fluid-bed equipment was conducted to enteric-coating using Eudragit~(R) L-30D-55 and sustained-release coating using Surelease~(R) . In vitro sinomenine hydrochloride release profiles of both uncoated and coated pellets were fitted to the chosen mathematical equations offered by the curve fitting toolbox of Matlab~(R) before a linear additive model was created based upon the best-to-fitting equations. The proportion of each pellet type in the combined format to generate the desired 24 h sinomenine hydrochloride release profile was solved by Matlab~(R). The predicted and assayed sinomenine hydrochloride release from the polled pellets was compared. Results: It was shown that the actual sinomenine hydrochloride release profiles of each pellet type were approximate to those of predicted ones. A linear additive model of the appropriate mathematical equations of each pellet was proven to be capable of controlling in vitro release of sinomenine hydrochloride multiple-unit pellets. Conclusion: A multiple-unit combined system of the selected pellets, as a novel sustained-release system, was successfully prepared. In vitro release performance of the calculated combination of each pellet type could be guaranteed by this approach in designing sustained-release drug delivery system.

Objective: This study aimed to translate the English version of the Perceived Competence Scale for Disaster Mental Health Workforce (PCS-DMHW) into Chinese, and to test its reliability and validity in Chinese mental health workers. Methods: With the consent of Professor Choi, Keimyung University, Korea, and the authorization of the scale, the English version of PCS-DMHW was translated, retranslated and culturally debugged to form the Chinese version of PCS-DMHW. The general information questionnaire and the Chinese version of PCS-DMHW scale were used to investigate 706 mental health workforce from 9 tertiary hospitals in Sichuan province in China from March 24, 2020 to April 14, 2020. The Cronbach’s α coefficient was used to evaluate the internal consistency reliability of the scale, and the test-retest correlation coefficient r was used to evaluate the test-retest reliability of the scale. The content validity indexes (CVI) and exploratory factor analysis (EFA) was used separately for evaluating the content validity and structure validity of the scale. Results: The Cronbach’s α coefficient of the Chinese version of PCS-DMHW total scale, individual competences and organizational competences subscale was 0.978, 0.956, and 0.964, respectively. The test-retest reliability of the total scale, individual competences and organizational competences subscale was 0.949, 0.932 and 0.927, respectively. The item-level CVI of all scale were ranged from 0.833–1.000, the scale-level CVI (S-CVI)/universal agreement of the total scale, individual competences and organizational competences subscale was 0.833, 0.875, and 0.857, respectively, and the S-CVI/average was 0.972, 0.979, and 0.976, respectively. EFA showed that two principal components were extracted from the subscale of individual competences and organizational competences. Conclusion The Chinese version of PCS-DMHW has good reliability and validity, and can be widely used in China.

Objective To evaluate the efficacy of rescue treatment for recurrent esophageal cancer after radical esophagectomy, and to provide insights into the development of comprehensive treatment for esophageal cancer.Methods The clinical data of 218 patients who were confirmed with recurrent metastatic esophageal cancer after R0 resection and received rescue treatment in our hospital from 2004 to 2014 were retrospectively reviewed.The survival rate was determined by the Kaplan-Meier method.Univariate and multivariate prognostic analyses were performed using the log-rank test and Cox proportional hazards model, respectively.Results The median post-recurrence follow-up time was 53 months.The 1-and 3-year overall survival (OS) rates after recurrence were 57.2% and 24.4%, respectively.Among the 163 patients with local recurrence, the 1-and 3-year OS rates were 70% and 42% for patients treated with chemoradiotherapy (n=40), 55% and 24% for those with radiotherapy alone (n=106), and 23% and 8% for those with supportive therapy (n=13)(chemoradiotherapy vs.radiotherapy alone P=0.045, radiotherapy alone vs.supportive therapy P=0.004;none of the patients who were treated with chemotherapy alone survived for one year or more).Univariate analysis showed that N staging, TNM staging, and post-recurrence rescue treatment regimen were independent prognostic factors for esophageal cancer (all P=0.001).On the other hand, multivariate analysis indicated that only rescue treatment regimen was the independent prognostic factor for esophageal cancer (P=0.013).Conclusions Rescue chemoradiotherapy or radiotherapy alone can bring significant survival benefits for patients with recurrent and metastatic, especially locally recurrent, esophageal cancer following radical esophagectomy.

OBJECTIVETo identify differentially expressed genes between chronic phase and blast crisis in chronic myeloid leukemia, explore the mechanism and screen potential biomarkers of disease progression.

METHODSThe differences in the gene expression profiles of bone marrow mononuclear cells between chronic phase and blastic crisis were examined using DNA microarray. PANTHER database, Genomatix database and Bibliosphere software were used to analyze and predict the critical genes or transcription factors during disease progression. Some of the genes or transcription factors were selected for verification by semi-quantitative RT-PCR.

RESULTSIn blastic crisis, 68 of the 1176 tested genes were obviously up-regulated. Sixteen of these differential genes were selectively expressed in leukocyte membranes. CD40, CCR3, LGALS3, RGS3, CEACAM3 and the related transcription factors RAC1, CTNNB1, TP53, and NF-κB, all as the nodes of the entire regulatory network, were presumed to play key roles in disease progression. The results of RT-PCR were consistent with the microarray data and showed high expression of CEACAM3, RGS3, CTNNB1 and RAC1 in blastic crisis.

CONCLUSIONA group of genes have been identified to very likely play key roles or serve as biomarkers in the transition from the chronic phase to blastic crisis in chronic myeloid leukemia.

Objective: This study explored whether anxiety and core self-evaluation mediate the relationship between negative life events and depressive symptoms in adolescents of the Yi ethnic minority in China. Methods: In this cross-sectional study, a convenience sample of 627 Yi adolescents 10–19 years old (252 males, 40.2%) from primary, middle and high schools in Liangshan Prefecture in China completed the Adolescent Self-Rating Life Events Checklist (ASLEC) to report on negative life events, the Second Edition of the Beck Depression Inventory (BDI-II) to report on depressive symptoms, the Core Self-Evaluations Scale (CSES) to describe core self-evaluation, and the Screen for Child Anxiety-Related Emotional Disorders (SCARED) to report anxiety symptoms. Results: In Pearson correlation analysis, total score and dimension subscores on the ASLEC correlated positively with total score and dimension subscores on the SCARED survey as well as with total score on the BDI. Total ASLEC score and dimension subscores correlated negatively with total CSES score. Mediation analysis indicated that negative life events affected depressive symptoms directly, as well as indirectly via core self-evaluation (mediating effect was 0.087; 95% confidence interval [CI], 0.063–0.113; p<0.001). The chain-mediated pathway effect was significant (mediating effect was 0.017; 95% CI, 0.011–0.026; p<0.001). Conclusion Yi adolescents in Liangshan Prefecture show certain prevalence of anxiety and depression, and they score relatively low on core self-evaluation. In this ethnic group, negative life events can affect depressive symptoms directly as well as indirectly through chain-mediated effects of anxiety and core self-evaluation.

Objective To explore the incidence and related predictive factors for acute symptomatic esophagitis in patients with locally advanced non?small cell lung cancer ( NSCLC ) treated with intensity?modulated radiation therapy ( IMRT) . Methods Data were collected retrospectively from 256 patients with inoperable or unresectable stage Ⅲ NSCLC treated in our hospital between January 2007 and December 2011. The radiotherapy target volume included primary lung cancer and lymphatic drainage area involved,with a median dose of 60 Gy in 30 fractions (50-70 Gy).Of all the patients,109 patients (42.6%) received concurrent chemotherapy. Grade ≥2 acute esophagitis ( AE ) ( symptomatic esophagitis ) which occurred during radiotherapy and within 3 months after completion of radiotherapy served as the outcome event. National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0( NCI?CTCAE3.0) was used to evaluate the grade of AE. The logistic regression model was used to analyze the predictive factors. Results A total of 174 patients ( 68%) had treatment?related grade ≥2 AE;154 patients ( 60. 2%) had grade 2 AE and 20 patients (7.8%) had grade 3 AE.The median dose when grade≥2 AE occurred was 30 Gy (11?68 Gy).For grade≥2 AE,multivariate analysis showed that esophageal V5?V60,mean dose,and age were independent predictive factors (P=0.021,0,0.010).For grade ≥3 AE,multivariate analysis showed that esophageal V50?V60 ,concurrent chemotherapy,and body mass index ( BMI) were independent predictive factors ( P= 0.010,0.003,0.019 ) . Old age and higher BMI were the protective factors for grade≥2 and ≥3 AE, respectively. Conclusions For patients with locally advanced NSCLC treated with IMRT, esophageal V50—V60 and concurrent chemotherapy are predictive factors for grade ≥3 AE,and esophageal V50 has a high predictive value for both grade ≥2 and ≥3 AE.
