Objective:To test whether the constructed intervention model of advance care planning (ACP) for patients with advanced cancer can be successfully implemented and the preliminary intervention effect, which provides reference for empirical research.Methods:32 cases of advanced cancer patients and 25 cases of their families at the Fifth Affiliated Hospital of Zunyi Medical University, Zhuhai were selected. The patients were subdivided into the experimental group and the control group by random number table method. The control group received routine nursing, while the experimental group adopted the intervention model of "VIP for future care" on the basis of customary nursing. We measured the main outcome indicators: enrollment rate, consent rate, completion rate and loss of follow-up rate and secondary outcome indicators: decision-making certainty, end-of-life care preference and post-intervention satisfaction of patients and their families, within 1 week and 1 month after intervention.Results:The enrollment rate, consent rate and loss of follow-up rate were 74.6% (206/276), 36.9% (76/151)and 15.6% (5/32), respectively. After intervention, the completion rates of the experimental group and the control group were 16/16 and 15/16 within one week, and 14/16 and 13/16 within one month. All of the family members were conducted during the follow-up period. The intervention mode of "VIP for future care" had a statistically significant difference in decision-making certainty between the two groups of patients ( β=0.63, 95% CI 0.08-1.18, P<0.05), no statistically significant difference in end-of-life care preference between the two groups of patients and their families ( P>0.05), and had a statistically significant difference in "whether to recommend this project to others" between the two groups ( χ2 value was 4.167 , P<0.05). Conclusions:On the premise of sufficient preparation, the "VIP for future care" intervention mode can be successfully implemented in advanced cancer patients in mainland China, can improve the decision-making certainty of patients and the satisfaction of patients and their families, and it is recommended. And should be applied to ACP intervention for patients with advanced cancer.

Objective:To study the effect of Compound Duzhong Jiangu Granules on joint function, quality of life and inflammatory factors in patients with Kashin-Beck disease.Methods:By group design, 135 patients with Kashin-Beck disease in Chongxin County, Pingliang City, Gansu Province, were selected and divided into intervention group (100 cases treated with Compound Duzhong Jiangu Granules, 12 g/bag, 1 bag/time, 3 times/day, treatment for 1 month) and control group (35 cases treated with ibuprofen, 0.3 g/capsule, 1 capsule/time, 2 times/day, treatment for 2 weeks) according to the randomized, single-blind principle. The changes of joint dysfunction index score, joint function improvement rate, total scores of Kashin-Beck disease quality of life (KBDQOL) and scores of each dimension were analyzed before treatment, 1 month and 3 months after treatment. The serum levels of interleukin-6 (IL-6), nuclear factor κB (NFκB)-p65, inducible nitric oxide synthase (NOS2), nitric oxide (NO), and prostaglandin E2 (PGE2) were detected by enzyme-linked immunosorbent assay before treatment and 1 month after treatment.Results:The total scores of joint dysfunction index of the intervention group and the control group 1 month after treatment and 3 months after treatment were lower than those before treatment, but 3 months after treatment was higher than 1 month after treatment ( P < 0.001). One month after treatment, the total effective rates of joint function improvement in the intervention group and the control group were 68.00% (68/100) and 54.55% (18/33), respectively; 3 months after treatment, the total effective rates of the intervention group and the control group were 36.00% (36/100) and 39.39%(13/33), respectively. The total scores and scores of each dimension of KBDQOL were not significant for the main effect of the group ( P > 0.05), but significant for the main effect at the time point ( P < 0.05), and there was no interactive effect ( P > 0.05). There were significant differences in the scores of social support and mental status dimensions in the intervention group at different time points ( P < 0.001). And in the intervention group, the total score, the scores of physical function, activity limitation, economy and overall health dimensions were statistically significant between before treatment and 1 month after treatment, 1 month after treatment and 3 months after treatment( P < 0.05); however, there was no significant difference between before treatment and 3 months after treatment ( P > 0.05). One month after treatment, the serum PGE2 levels of both groups were decreased ( P < 0.05), and there was no difference in other inflammatory factors at different groups and time points ( P > 0.05). Conclusion:Compound Duzhong Jiangu Granules can effectively inhibit the inflammatory reaction of patients with Kashin-Beck disease, promote the improvement of joint function and improve the quality of life in various aspects.

Relying only on the ethics committee to protect subjects is not enough, and the construction of the subject protection system is an inevitable trend for the protection of subjects’ rights. This paper elaborated on the current situation of Chinese subject protection system from four aspects: the lack of laws and regulations and administrative supervision, the insufficient attention of hospitals, poor construction of the subject protection system, and the absence of responsibilities of relevant personnel. Then this paper put forward countermeasures from three aspects: improving laws and regulations and strengthening supervision, mobilizing relevant departments to participate, and strengthening relevant training, in order to standardize the construction of the subject protection system and promote the development of the subject protection work.

OBJECTIVE: To investigate the difference of tumor formation in different mouse strains bearing patient-derived xenograft of esophageal squamous cell carcinoma(ESCC) and establish a better animal model for preclinical study of individualized treatment of ESCC. METHODS: The tumor tissues collected from 22 ESCC patients were used to establish tumor-bearing mouse models in B-NDG (NSG) mice and BALB/c nude mice. The tumor formation rate and tumor formation time were compared between the two mouse models, and HE staining, immunohistochemistry and genome sequencing were carried out to assess the consistency between transplanted tumor tissues in the models and patient-derived tumor tissues. RESULTS: The tumor-bearing models were established successfully in both NSG mice (50%, 11/22) and BALB/c nude mice (18.18%, 4/22). The average tumor formation time was significantly shorter in NSG mice than in BALB/c nude mice (75.95 91.67 days, < 0.001). In both of the mouse models, the transplanted tumors maintained morphological characteristics identical to those of patient-derived ESCC tumors. Genetic analysis showed that the xenografts in NSG mice had a greater genetic similarity to the patients' tumors than those in BALB/c nude mice ( < 0.0001). CONCLUSIONS Mouse models bearing xenografts of patient-derived ESCC can be successfully established in both NSG mice and BALB/c nude mice, but the models in the former mouse strain can be more reliable.
