Postoperative Adjuvant Transarterial Chemoembolization Plus Tyrosine Kinase Inhibitor for Hepatocellular Carcinoma: a Multicentre Retrospective Study.

Purpose: This study aimed to assess the efficacy and safety of adjuvant transarterial chemoembolization (TACE) plus tyrosine kinase inhibitor (TKI) treatment in patients with hepatocellular carcinoma (HCC) with a high risk of early recurrence after curative resection. Patients and Methods: Patients from multiple centres were divided into postoperative adjuvant TACE with (n=57) or without (n=142) TKI administration groups. The disease-free survival (DFS) curve was depicted by the Kaplan-Meier method, and the difference between the two groups was tested using the log rank test. Univariate and multivariate Cox analyses were performed to identify independent risk factors for DFS. Additionally, three propensity score analyses were performed to minimise the potential confounding factors to facilitate a more reliable conclusion. Adverse events (AEs) were assessed according to the Common Terminology Criteria for Adverse Events, version 4.0. Results: The 1-and 2-year DFS rates of the TACE plus TKI treatment group were 45.5% and 34.9%, respectively, which were significantly better than those of the TACE alone group (26.8% and 18.3%, respectively). Multivariate analysis identified adjuvant TACE plus TKI treatment as an independent prognostic factor for DFS (hazard ratio: 0.611, 95% confidence interval: 0.408-0.915, P=0.017). Further analysis based on the various propensity score methods yielded similar results. Subgroup analysis showed that patients with tumour diameter ≥5 cm, tumour number <3, absence of hepatic vein tumour thrombus and bile duct tumour thrombus, ruptured tumours, and stage IIIB could benefit more from TACE plus TKI treatment (all P<0.05). Some patients (33.33%) experienced grade ≥3 AEs in the TACE plus TKI group. Conclusion: TACE plus TKI treatment can reduce the incidence of early recurrence with tolerable adverse events in HCC patients at high risk of recurrence after hepatectomy and may be an appropriate option in postoperative anti-recurrence treatment.

Controllable local electronic migration induced charge separation and red-shift emission in carbon nitride for enhanced photocatalysis and potential phototherapy.

Electronic migration can be tailored by carefully manipulating the local electron donating and withdrawing nature of carbon nitride for charge separation and red-shift emission. A high yield of H2 (5 mmol h-1 g-1) with an apparent quantum yield of 20.98% at 420 nm and a preliminary study on phototherapy by labeling cell membranes are simultaneously provided.

[The influence of elective course of emergency treatment for medical students on the cultivation of first aid knowledge and skill of cardio-pulmonary resuscitation].

OBJECTIVE: To investigate the influence of elective course of emergency treatment for medical students on the cultivation of first aid knowledge and skills of cardio-pulmonary resuscitation. METHODS: Senior students major in medicine of our university were randomly divided into observation group and contrast group with 30 students in each group according to whether an elective course of emergency treatment was given or not. All of them then received a test of first aid knowledge and cardio-pulmonary resuscitation skills. RESULTS: The theoretical exam scores in observation group and contrast group were respectively 78.5+/-9.1 and 46.7+/-15.6. The scores in observation group were significantly higher than that in contrast group (P < 0.01). Cardio-pulmonary resuscitation skills scores in observation group and contrast group were respectively 7.32+/-0.83 and 6.63+/-0.91. The scores in observation group were significantly higher than that in contrast group (P < 0.01). The number of failure for closed cardiac massage in 60 times in observation group and contrast group was respectively 5.06+/-0.58 and 5.77+/-0.63. The number of mouth to mouth artificial respiration in 4 times in observation group and contrast group was 0.92+/-0.16 and 1.10+/-0.17, respectively. There were notable differences in the number of failure in resuscitation maneuvers between two groups (both P < 0.01), observation group being obviously poorer than contrast group. CONCLUSION: An elective course of emergency treatment given to medical students plays an important role in the cultivation of first aid knowledge and skills in cardio-pulmonary resuscitation. It is therefore necessary that emergency medicine is included as a required course in medical college.
