To investigate amethod which could prolong the efficient time of morphine and decrease side effect. Met hods:100 patients were randomly divided into four groups, receiving the different dispensation of analgesia. Analgesic solutions were given into epi dural space 510 minutes before operation was finished. Analgesic efficiency, efficient time, and side effects were recorded. esult: Sol utions diluted with hypertonia glucose injection might prolong the efficient time obviously (P＜0.01). When combined with bupivacaine or scopolamine the sid e effects were decreased. Conclusion: Morphine combined wi th bupivacaine or scopolamine diluted with hypertonis glucose injection, used in epidural analgesia, can bring longer efficient time and less side effects.

OBJECTIVETo screen differentially expressed genes and identify potential signaling pathway in Asian people with breast cancer.

METHODSFive gene microarray datasets of Asian people with breast cancer, GSE6367, GSE9309, GSE15852, GSE33447 and GSE45255, were downloaded from GEO. Microarrays with 318 breast cancer and 60 normal breast tissues were used for analysis of differentially expressed genes and pathway. 32 pairs of breast cancer patients' specimens were used to validate the differentially expressed genes by real-time PCR.

RESULTSAnalysis of the large sample of microarray data identified 436 differentially expressed genes in breast cancer tissues, while 259 of these genes were up-regulated and the other 177 down-regulated. Pathway analysis showed that metabolism-related signaling pathway may be involved in the development of breast cancer in Asian people. The expressions of KRT19, ADIPOQ, CFD, RBP4, LPL, ABCA8 and CD36 genes were confirmed by real-time PCR.

CONCLUSIONThis study shows differential gene expression profile and potential signaling pathway in Asian people with breast cancer. CD36 gene may be closely related to the Asian breast cancer. ABCA8 gene may be a new disease gene in Asian breast cancer.

Objective To compare the long-term survival outcomes of patients with T_1-2N₀M₀ duodenal neuroendocrine tumor (DNET) after endoscopic resection (ER) or surgical resection (SR). Methods Patients diagnosed with T_1-2N₀M₀ DNET between January 1, 2004, and December 31, 2015, were extracted from the SEER database. Kaplan-Meier survival curve and log-rank test were used to compare overall survival (OS) rate and cancer-specific survival (CSS) rate between patients undergoing ER or SR. Propensity score matching (PSM) was used to reduce grouping differences, and multivariate Cox regression was used to analyze factors affecting OS and CSS before and after PSM. Results A total of 656 patients were included, with 457 in ER group and 199 in SR group. Before PSM, there was no significant difference in the 5-year OS rate between the ER and SR groups (88.9% vs 89.6%), but there was a significant difference in the 5-year CSS rate (99.3% vs 96.9%, P＝0.017). Before PSM, multivariate Cox regression analysis showed advanced age was an independent risk factor for decreased OS (P＜0.001). After PSM, there was no significant difference between the ER group (n＝187) and SR group (n＝187) in 5-year OS rate (90.2% vs 88.9%) or CSS rate (98.9% vs 96.7%). After PSM, multivariate Cox regression also showed advanced age was an independent risk factor for decreased OS, while resection method was not an independent factor for OS or CSS. Conclusions There is no significant difference in OS or CSS after endoscopic treatment and surgical treatments for patients with T_1-2N₀M₀ DNET, and advanced age is an independent factor for OS.
