Since the 18th CPC National Congress,General Secretary Xi Jinping has attached great significance to health assistance for foreign countries,and has made a series of important instructions.China's health assistance for foreign countries has entered a new era of development and cooperation,and has made an important contribution to the promotion of building a global community of health for all.The First Affiliated Hospital,Sun Yat-sen University has actively responded to the national strategy and send medical experts to over 11 countries along the"Belt and Road"region,such as Ghana,Equatorial Guinea,Fi-ji,Serbia,Dominica,and so on.The First Affiliated Hospital,Sun Yat-sen University has won awards at home and abroad for its efforts,including the National Advanced Group for health assistance for foreign countries,the National Advanced Individual for health assistance for foreign countries,and the Serbian Government's Gold Medal of Merit.Taking medical experts in Serbia and Dominica as examples,the author focuses on building a global reputation,and summarizes a series of initiatives from The First Affiliated Hospital,Sun Yat-sen University,including the creation of a multi-level and whole-process management system,the cohesion of back-up strength for health assistance for foreign countries.

Objective: To investigate the correlation between skin elasticity and setup error in optical surface image-guided radiotherapy. Methods: The skin elasticity (R7) data of the head, chest and abdomen were extracted and analyzed its correlation with age by systematic literature review. Fifty-four patients diagnosed with nasopharyngeal carcinoma, breast cancer and cervical cancer were recruited in this study. Firstly, the patients were positioned based on the room laser and markers. Subsequently, the patient position was verified by the Varian On-Board Imager, and then C-Rad Catalyst was adopted to obtain surface images in two states (mask or non-mask) as reference images. In the subsequent fraction treatment, after initial positioning, the local calibration was performed by Catalyst, and setup errors in three directions were recorded. Meanwhile, the patient setup was verified by CBCT twice a week. The Pearson correlation analysis was performed to analyze the correlation between setup error and age. Results: The skin elasticity was negatively correlated with aging (P<0.01). The correlation coefficient between random error and age in head-and-neck cancer were 0.645, 0.624 and 0.866 in the AP, SI and LR directions (all P<0.05) for male patients without mask, respectively. The system error was significantly correlated with age in the LR direction (P<0.05) for male patients, and in the AP direction (P<0.05) for female patients with head-and-neck cancer without mask. The setup error had a significant correlation with skin elasticity in male patients with head-and-neck cancer, and the sequence of absolute value of correlation coefficient was LR>SI>AP. Conclusion In optical surface-guided radiotherapy of head and neck cancer, skin elasticity may be a significant index for assessing the setup errors in male patients.

Objective: To investigate the effect of an information module for delirium assessment in ICU. Methods: The information module for delirium assessment was designed according to the route chart of the Confusion Assessment Method for the Intensive Care Unit(CAM-ICU) information assessment. Totally 70 nurses Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were included in the application of the information module. The compliance and accuracy of the delirium assessment and acceptance of nurses' assessment of information module were compared. Results: The information module for delirium assessment was implanted into the clinical critical information system. The rate of compliance and accuracy of delirium assessed was 55.9%(2 728/4 877), 64.2%(231/360) before the application of information module, and 92.0%(4 360/4 740), 92.5%(333/360) after the application of information module. The difference between two groups were statistically significant (χ²=1 611.531, 85.139, P<0.01). The score of nurses′ acceptance of the input method before and after the application of information module were 69.00±4.00, 100.56±3.50, and the difference were statistically significant (t=-49.70, P<0.01). Conclusions The information module for delirium assessment can simplify the assessment process, improve nurses′ compliance and accuracy to assess delirium, optimize critical care management and worth spreading.

BACKGROUNDGallbladder carcinoma (GBC) has a high mortality rate, requiring synergistic anti-tumor management for effective treatment. The myxoma virus (MYXV) exhibits a modest clinical value through its oncolytic potential and narrow host tropism.

METHODSWe performed viral replication assays, cell viability assays, migration assays, and xenograft tumor models to demonstrate that bone marrow-derived stem cells (BMSCs) may enhance efficiency of intravenous MYXV delivery.

RESULTSWe examined the permissiveness of various GBC cell lines towards MYXV infection and found two supported single and multiple rounds of MYXV replication, leading to an oncolytic effect. Furthermore, we found that BMSCs exhibited tropism for GBC cells within a Matrigel migration system. BMSCs failed to affect the growth of GBC cells, in terms of tumor volume and survival time. Finally, we demonstrated in vivo that intravenous injection of MYXV-infected BMSCs significantly improves the oncolytic effect of MYXV alone, almost to the same extent as intratumoral injection of MYXV.

CONCLUSIONThis study indicates that BMSCs are a promising novel vehicle for MYXV to clinically address gallbladder tumors.
