BACKGROUNDIn recent years, the prevalence of type 2 diabetes among Chinese population has been increasing by years, directly leading to an average annual growth rate of 19.90% of medical expenditure. Therefore, it is urgent to work on strategies to control the growth of medical expenditure on type 2 diabetes on the basis of the reality of China. Therefore, in this study, we explored the feasibility of implementing bundled payment in China through analyzing bundled payment standards of type 2 diabetes outpatient services.
METHODSThis study analyzed the outpatient expenditure on type 2 diabetes with Beijing Urban Employee's Basic Medical Insurance from 2010 to 2012. Based on the analysis of outpatient expenditure and its influential factors, we adopted decision tree approach to conduct a case-mix analysis. In the end, we built a case-mix model to calculate the standard expenditure and the upper limit of each combination.
RESULTSWe found that age, job status, and whether with complication were significant factors that influence outpatient expenditure for type 2 diabetes. Through the analysis of the decision tree, we used six variables (complication, age, diabetic foot, diabetic nephropathy, cardiac-cerebrovascular disease, and neuropathy) to group the cases, and obtained 11 case-mix groups.
CONCLUSIONSWe argued that it is feasible to implement bundled payment on type 2 diabetes outpatient services. Bundled payment is effective to control the increase of outpatient expenditure. Further improvements are needed for the implementation of bundled payment reimbursement standards, together with relevant policies and measures.

OBJECTIVEThe aim of the study was to review the cases of Kawasaki Disease (KD) and analyze the clinical features especially their cardiac complications.
METHODSTotally 283 patients with KD were hospitalized from 1992 to 2002. Their clinical features and factors associated with increased risk of coronary artery aneurysms were reviewed.
RESULTS(1) Among the 283 KD patients, 186 were male and 97 were female. The male-female ratio was 1.9:1. Most of them (71%) were younger than 3 years old. Seasonal peak was in spring and summer (from May to Aug). Depending on the criteria of KD, 228 (81%) were diagnosed as typical KD and 55 (19.4%) were atypical KD. All patients had fever, lasting for 6.1 days. The most common clinical features were oral mucosal changes (97.5%) and cervical lymphadenopathy (95.4%), conjunctivitis (91.2%). And changes in the extremities (89.8%) and rash (81.5%) were also noted. (2) Before the treatment, coronary artery abnormalities were seen in 103/279 (36.9%), which occurred within 4 - 30 days of fever onset. Two weeks after intravenous gamma globulin (IVIG) treatment, the new cases of coronary artery abnormalities were 28/211 (13.3%). The prevalence of coronary artery aneurysms (CAA) with KD was 4.7%. The risk factors of CAA were male cases (P < 0.05) and fever lasting longer than 9 days (P < 0.05). Other cardiac abnormalities in acute phase included left atrial and ventricular enlargement (40/279, 14.3%) and changes in ECG (57/274, 20.8%). The pericardial effusions were found in 11 cases (3.9%).
CONCLUSIONSCardiac complications of KD occurred in the early period of KD. The new cases of coronary artery abnormalities were 13.3% after IVIG treatment. The risk factors of CAA included male cases and fever lasting for longer time.

OBJECTIVE:
To analyze the clinical effect of Zhuang medicine tendon therapy combined with chiropractic manipulation in treating sacroiliac joint dislocation.
METHODS:
From January 2017 to May 2018, 60 patients with sacroiliac joint dislocation were divided into treatment group and control group according to the order of admission. There were 19 males and 11 females in the treatment group, aged from 23 to 52 (38.97±3.23) years old, with a course of 2 h to 5.1 months, with an average of (2.19±1.12) months. There were 14 males and 16 females in the control group, aged from 26 to 50 (39.07±3.30) years old, with a course of 3 h to 6 months, with an average of(2.41±1.05) months. The treatment group was treated with Zhuang medicine tendon therapy combined with chiropractic manipulation, while the control group was treated with conventional acupuncture and massage. Before treatment, the main clinical symptoms of the patients were lumbosacral pain, posterior superior iliac spine not at the same level and accompanied with dyskinesia. The pelvic separation test and the "4" test were positive. After treatment, the curative effect was evaluated according to the improved Macnab standard and the "score of treatment of lumbar diseases".
RESULTS:
Sixty patients were followed up for an average of 8 months. At the latest follow-up, the clinical effect of modified Macnab was better in the treatment group than in the control group(<0.01). After treatment, the treatment group was better than the control group on lumbar function score (<0.01).
CONCLUSIONS
The treatment of sacroiliac joint dislocation by Zhuang medicine tendon therapy combined with chiropractic manipulation has good clinical effect and is worth further application and development.
