Objective To investigate the changes of first-phase insulin secretion and its components in the first-degree relatives of Chinese type 2 diabetics with normal glucose tolerance and their correlation with type 2 diabetes. Methods The first-degree relatives of type 2 diabetes (Group B, n=35), newly diagnosed type 2 diabetic patients (Group C, n=35) and health subjects (Group A, n=21) were recruited. Immune reactive insulin (IRI), proinsulin (PI), and true insulin (TI) were determined during intravenous glucose tolerance test (IVGTT) in each subjects. IRI was determined with radioimmunoassay kit, while PI and TI with ELISA kits. Results (1) For the fasting sera, the levels of IRI and PI showed significant differences (both P

Objective:To investigate the therapeutic medication for inpatients with cancer pain, and compare with the latest cancer treatment guidelines to improve the rational drug use. Methods:By a retrospective study, the medical record analysis for the inpatients with cancer from October to December in 2014 was performed, and the incidence of pain and the therapeutic medication were investiga-ted and the rationality of drug use was evaluated based on the latest cancer pain treatment guidelines. Results:The incidence of cancer pain was 25. 46% of 774 cases with new cancer, and 76. 58% of the patients with cancer pain were treated with analgesic drugs. In ac-cordance with the guidelines for the treatment scheme, there was no significant difference between the Opioid-Naive group ( guide group 1) and the Opioids-Tolerant group (guide group 2) in the combination therapy, while there was significant difference in the drug selec-tion and the time of administration. In the guide group 1 the proportion of oxywdone controlled-release tablets was signiticantly higher than that in the guide group 2, the ratio of taking the medicine on time in the guide group 1 was also higher than that in the guide group 2. Both groups showed difference from the guidelines in the pain assessment and titration and specific analgesic drug use. Conclusion:The findings indicate the difference between the pain treatment and the guidelines in therapeutic medication of cancer pain, and the propaganda and education of relevant knowledge should be strengthened to promote the treatment standard.

Identification and determination of hyoscine in Zhichuanling Injection were carried out by TLC. It was suggested that TLC-colorimetry could be sued to determine hyoscine content. The method showed a good separation,high specificity,but lower requirement for apparatus.

Objective Through the determination of the insulin receptor and its signal transducers,we tried to find the defects in the common pathway of insulin signal transduction in type 2 DM and to lay a foundation to discover the pathogenesis and effective drugs.Methods Using 32 P-labeling method to determine the activity of TPK and MAPK.Using Fluo 3-AM as fluorescent probe to determine intracellular calcium of patients with type 2 DM.Using photometry to determine the concentration of NO.Results The activities of TPK,MAPK remarkably descended and the concentration of NO also greatly descended compared with healthy people.The concentration of intracellular calcium increased compared with healthy people.Conclusion The defects of the related signal molecule in insulin signal transduction of type 2 DM existed.

Objective:To detect the pain status and the pain management of home-based advanced cancer patients, and to investigate the key factors impacting the satisfaction on pain management.Methods:Totally the data of 138 cases from the hospice department in the duration from Jan. 2019 to Jun. 2019 were collected and analyzed by χ2 test with SPSS 23.0. Results:109 cases in 138 cases received analgesics treatment before, 54.13% of these participants expressed satisfaction with the effect of their pain management, and 45.87% showed unsatisfied on their pain management. Cancer clinical stage and PMI (pain management index) were both detected to be the significant factors for satisfaction of pain management ( P<0.05, P=0.029; P<0.01, P=0.001) . Conclusions:Cancer clinical stage and PMI are found to be related to the satisfaction for pain management. The percentage of patients who use opioids increased. while there was still a part of patients suffering from inadequacy of pain management. The pain management for home-based advanced patients needs to be paid more attention by medical staff.

BACKGROUND:Anticancer drug deguelin delays the embryonic development of zebrafish, but its exact mechanism is not yet clear.
OBJECTIVE:To explore expression differences in genes and signaling pathways in deguelin-treated zebrafish embryos.
METHODS:Zebrafish embryos were harvested from zebrafish fed according to the Zebrafish Book. Zebrafish embryos at 2-cel stage were selected and divided into two groups:control group treated with dimethyl sulfoxide incubator liquid, and experimental group treated with 0.6μmol/L deguelin. Total RNA was extracted from the two groups at sphere stage. Then, gene chip technique was used to detect differential y expressed genes in the deguelin-treated zebrafish embryos. Real-time quantitative PCR was employed to validate microarray cluster analysis and pathway analysis to explore the mechanism of action of deguelin.
RESULTS AND CONCLUSION:Chip results showed that 407 genes were upregulated more than three times and 461 genes were downregulated more than three times after deguelin treatment. PCR validation results were consistent with those of the chip. Fourteen pathways were identified by KEGG pathway analysis. Deguelin may play an important role by intervening cel metabolism growth and differentiation.

Objective: To investigate the relationship between HLA-DR4/1 subtypes and T cell responses to type Ⅱ collagen or anti-CⅡ263-272 antibodies. Methods: Peripheral blood mononuclear cells and sera were obtained from 70 rheumatoid arthritis (RA) patients. T cell proliferative responses to CⅡ263-272 were evaluated by 3H thymidine incorporation assay. Antibodies specific to CⅡ263-272 were determined by ELISA. HLA-DR4/1 subtypes were analyzed by PCR-SSP. Results: In HLA-DR4/1 positive group, T cell proliferative responses to CⅡ263-272 were observed in 55.6% RA patients and anti- CⅡ263-272 antibodies were present in 66.7% RA patients. In HLA-DR4/1 negative group, T cell proliferative responses to CⅡ263-272 were observed in 30.3% RA patients and anti-CⅡ263-272 antibodies were present in 34.8% RA patients. The number of positive antibodies to CⅡ263-272 or T cell proliferative responses to CⅡ263-272 in HLA-DR4/1 positive group were higher than in negative group. Conclusion: There is a relationship between HLA-DR4/1 subtypes and T cell responses to CⅡ263-272 or anti-CⅡ263-272 antibodies.
