Objective Using DRG to analyze the impacts on inpatient costs of a hospital in Guangzhou as incurred by clinical pathway management. Methods As performed by BJ-DRGs, we selected DRG grouping information and medical record homepage information of the inpatients discharged from a tertiary hospital in Guangzhou in 2016. Then we compared the impacts of clinical pathway management on overall inpatients costs and the difference of inpatient costs for the DRG group. Results The median of inpatient costs in the clinical pathway group was 9239.41 yuan, was lower than that of control group which was 12358.06 yuan, and the difference was statistical difference (P<0.001). Cost composition analysis found that the costs of treatment, examination, medicine, surgery and the others in the clinical pathway group were much lower than that of the control group, while the cost of materials was relatively high. Among the 14 DRG group study, there were 6 DRG groups which the inpatient costs of the clinical path group was obviously lower than the control group. Conclusion The implementation of clinical pathway management may reduce the inpatient costs and change the makeup of costs. Therefore, combining with DRG, we actively promote the refined management of clinical pathway, which may effectively control the costs of diseases and the unreasonable growth of medical expenses.

Objective To investigate the immunophenotype features of children with acute B-lymphoblastic leukemia(B-ALL) combined with fusion gene expressing after to analyze the results of the 43 fusion genes. Methods Real-time fluorescent probe PCR assay was used for the detection of fusion genes in 120 cases of children from Shenzhen Children's Hospital with B-ALL newly or recurrently diagnosed from Oct 2016 to Dec 2018. Multi-parameter flow cytometry(FCM) was used for the detection of the immunophenotype in children with B-ALL. Results Of all the 120 cases, the fusion genes were detected at positive rate of 37.5%(45/120), included TEL/AML1 27 cases, E2 A/PBX1 7 cases, BCR/ABL1 6 cases, MLL 4 cases, TLS/ERG 1 cases. The positive rate of leukemia fusion gene had statistically difference among fusion genes positive groups based on age(P<0.01). There was no statistically difference in the gender distribution(P>0.05). The expressing of CD19 was at positive rate of 100% in all of the groups. The rate of the common-B-ALL was the highest B-ALL subtype in the TEL/AML1 positive groups(77.8%). The stem /progenitor associated antigen CD34 was at positive rate of 81.5%. The pre-B-ALL was the main subtype in the E2 A/PBX1 group, which was no expression of the known T-ALL associated antigen MyAg antigen. There was statistically difference in the positive rate of MyAg expression among all of the groups(P<0.01), with the highest rate in the BCR/ABL1 group(100%). Conclusion There were certain distribution features in age composition and immunophenotype of children with B-ALL carrying five kinds of common fusion genes. The characteristic changes of the immunophenotype of B-ALL may be used to predict the expression of fusion genes and improve the accuracy of fusion genes by the supplementary role of immunophenotype analysis.

Objective To detect the expression of peripheral blood circulating tumor cells CTC in patients with primary liver cancer and to explore the dynamic changes of CTC and its predictive effect on postoperative recurrence and metastasis of primary cancer. Methods The number of CTC in peripheral blood was measured in 134 patients with primary liver cancer and 72 patients with benign liver disease, the expression of AFP was detected, and the correlation between CTC and AFP was analyzed. Then 86 patients with primary liver cancer were selected from 134 patients with primary liver cancer who underwent radical hepatectomy. The values of CTC and AFP in evaluating recurrence and metastasis of primary liver cancer before and after operation were analyzed by CTC and AFP, in peripheral blood of these 86 patients. Results The positive rates of CTC in peripheral blood of patients with primary liver cancer were higher than that of patients with benign liver disease(P< 0.05). The levels of CTC in patients with primary liver cancer were related to AFP level, lymph node metastasis and the number of tumor nodules, but not to age, sex, tumor diameter, differentiation degree, liver cirrhosis and TNM stage. The survival analysis of CTC and AFP in patients with primary liver cancer showed that the early recurrence and metastasis of primary liver cancer after radical resection were closely related to the positive rate of CTC and AFP, and the positive rate of CTC was more effective than that of AFP positive in the diagnosis of recurrence and metastasis after operation, and the combination of the two had the highest predictive value for recurrence and metastasis. Conclusion CTC may be used as a better index to monitor postoperative recurrence and metastasis of primary liver cancer than traditional tumor markers. The combined detection prediction value of tumor markers is higher.
