1.An empirical analysis on the substitution effect of outpatient services on inpatient services
Journal of Peking University(Health Sciences) 2015;(3):459-463
Objective:To study the substitution effect of outpatient services on inpatient services and provide suggestions on designing outpatient policies. Methods:The data were from 13 districts/counties in one area of eastern China from 2007 to 2013 for the new cooperative medical scheme. This study em-ployed a fixed effects model to analyze the impacts of outpatient visit times, expenditure amounts and re-imbursements on inpatient services. Results: One outpatient visit reduced the total amount of inpatient services by 20 Yuan. An increase of 10 000 Yuan outpatient reimbursements saved 9 700 Yuan inpatient expenses. An increase of 10 000 Yuan outpatient expenses led to a decrease of 3 000 Yuan inpatient re-imbursements. The outpatient services did not increase the inpatient hospitalization times significantly. In particular, the effects of the outpatient services were mainly on the inpatient services at the district/coun-ty levels, and no significant impacts on the outpatient services at the city levels. Conclusion:There is a substitution effect of outpatient services on inpatient services. The health insurance departments should take this substitution effect into account and shift more funds on outpatient series, when they design out-patient and inpatient reimbursement policies.
2.Effects of Onodera's prognostic nutrition index(PNI)on the survival of patients with gallbladder carcinoma
Chinese Journal of Clinical Oncology 2014;(22):1450-1453
Objective:To retrospectively evaluate the prognostic risk factors of patients with gallbladder carcinoma and the effect of normal prognostic nutrition index (PNI) on the survival. Methods:We retrospectively analyzed 63 patients with gallbladder carcino-ma treated in our hospital between January 2008 and December 2012. The independent prognostic factors of the patients were calculat-ed by the Cox proportional hazards model. The benefit of normal PNI status on the prognosis was further explored in the patients using survival analysis. Results:Lymph node metastasis, PNI≤50, squamous carcinoma, liver invasion and choledoch invasion were the risk factors of overall survival (OS) in the univariate analysis, while only lymph node metastasis (HR=4.495, 95%CI 2.380~8.488, P<0.001) and PNI(HR=0.195, 95%CI 0.098~0.389, P<0.001) were the dependent influential factors of the prognosis and OS in the multi-variate analysis. The effect of PNI on OS was even more statistically significant different in the younger patients (≤65y) than in the el-der (>65y) (younger group:P=0.011;elder group:P=0.078). Conclusion:The gallbladder carcinoma patients with normal PNI status (>50) have better OS compared to the patients with PNI≤50, with statistical differences between the two. And it is more significant in the patients of the younger group (≤65y), comparing with the elder group. PNI could be taken as a potential prognostic evaluation factor for the gallbladder carcinoma patients and can provide a more comprehensive evaluation of patients' conditions to clinician.

7. Study on fingerprint of Zhishi-Xiebai-Guizhi Decoction by HPLC and determination of 10 index components
Chinese Traditional and Herbal Drugs 2020;51(9):2448-2459
Objective: To establish an HPLC fingerprint analysis method of Zhishi Xiebai Guizhi Decoction (ZXGD) and the content determination method of 10 index components of the decoction, and carry out the relevant evaluation and analysis. Methods: HPLC method was used to establish the fingerprint analysis method of ZXGD and then similarity evaluation was carried out. Ten index components of the decoction were determined, the influence of the change of compatibility of medicinal materials on the content of index components was analyzed. Cluster analysis and other chemometrics methods were used to analyze the relevant data and evaluate the impact and value of quality control related indicators of ZXGD. Results: The similarity of 10 batches of samples ranged from 0.376 to 0.990, and that of five batches was more than 0.9, which indicated that the similarity of 10 batches of samples was quite different. In 10 batches of samples, S1, S2, S3, S5, S6, S8 and S10 were in one group, S4 and S9 were in one group, S7 was in one group. In this study, 30 characteristic peaks were calibrated, and principal components 1-6 was the main factor affecting the quality evaluation of medicinal materials. Among the 30 characteristic peaks, peak 21 (neohesperidin), 26, 29 (honokiol), 3, 23, 17, 30 (magnolol), 5, 24 (coumarin), 28, and 7 were the key components. The results showed that except quercetin, the other nine components had good linear relationship, precision, stability and repeatability in the range of mass concentration. Different compatibilities could increase or inhibit the dissolution of related components in medicinal materials. Conclusion: The HPLC method can be used for the simultaneous determination of ten chemical components in ZXGD. The method is efficient, accurate and reproducible, and can be used for the quality control and evaluation of ZXGD.

Objective To study expression and clinical significance of nm23 genes in primary breast carcinomas. Methods The expression of nm23 was detected by immunohistochemical S-P method in 286 cases of primary breast carcinomas. Results The positive rate of nm23 expression was 65.7%. There was not a significant correlation between the positive rate of nm23 and patients' age, tumor pathological types. There was a significant relation between the expression of nm23 and tumor clinical stage, axillary lymph node metastasis, and the positive rate of nm23 expression in the cases of clinical stage I without axilliary lymph node metastasis was significantly higher than that in the cases of clinical stage III with axilliary lymph node metastasis. Conclusion The expression of nm23 gene was negatively related with clinical stage and axilliary lymph node metastasis in breast carcinomas, which indicated that nm23 gene expression may serve as an index for predicting lymph node metastasis and the prognosis of breast carcinoma.
