OBJECTIVE:To study the factors affecting the compatible stability of amphotericin B(AmB)and 5%glucose injec-tion from different manufacturers,and to provide reliable evidence for the selection of solvent carrier of AmB. METHODS:After the combination of AmB and 5%glucose injection from different manufacturers(manafactarer A,B,C,D,E),it was shielded from light with room temperature(25℃)for 0,1,2,4,6 and 8 h. HPLC was conducted to determine the content changes of AmB in samples and observe the character,clarity and pH values. RESULTS:With the prolonging of time,insoluble impurities were detected in AmB and 5%glucose injection with the pH value less than 4.2 and the content of main drugs was decreased. Only 5%glucose injection from manufacturer A was in line with the requirements of AmB compatibility. CONCLUSIONS:The compatible stability of AmB and 5%glucose injection is closely related to pH values. It is suggested that manufacturers of infusions make clear descriptions of the pH value to select suitable infusions and safe drugs.

To study the influence of individualized medication guidance based on an Short Messaging Service( SMS) platform on the medication compliance in the patients with diabetes. Methods: Totally 100 cases of diabetic patients from the outpa-tient section were randomly divided into two groups using a number method with 50 ones in each, namely odd number was in the obser-vation group and even number was in the control group. The observation group was given pharmaceutical guidance based on the SMS technology platform by pharmacists, and the control group was given telephone follow-up once a week to understand the medical situa-tion. At the beginning of the study and after three-month treatment, the medication compliance in the two groups was evaluated, and the control situation of blood glucose was also compared. Results:There was no significant difference in the medication compliance be-tween the two groups at the beginning (P>0. 05). After the 3-month treatment, the blood glucose and medication compliance between the two group had statistical significance (P<0. 01). Conclusion:Based on a mobile phone short message technology platform, indi-vidualized clinical pharmaceutical guidance can significantly improve the medication compliance in diabetic patients.

AIM:Studies on totipotential stem cells using primordial germ cells (PGCs) have the same application prospect as embryonic stem cells, especially for the animals difficult to isolate embryonic stem cells from blastula. In vitro culture condition of embryo germ cells is the key to control this. This study designs a method to effectively amplify PGCs of mice in vitro and establishes an effective culture method of PGCs. METHODS: Experiments were carried out in the Department of Histology and Embryology of Chongqing Medical University and Key Laboratory of Biochemistry and Molecular Pharmacology from October 2006 to August 2007. ①Clean Kunming pregnant mice (embryos 0.5 dpc) were provided by Animal Experimental Center of Chongqing Medical University. Experimental procedures met the animal ethical standards. ②Allantois and surrounding tissues of 8.5 day post coitum (dpc) embryos, the hindhut and surrounding tissues of 9.5 dpc and 10.5 dpc embryos, the gonadal ridges and surrounding tissues of 11.5 dpc and 12.5 dpc embryos were collected and digested with 0.25%pancreatin-0.02%EDTA, then the cells were cultured in the plastic petridishes which are pretreated with 0.1% gelatine. The formation ratio of primary and the first passaged Embryonic germ (EG) clones were compared among those different time points. The SSEA-1 positive ratio of isolated cells was compared between the two days by immunohistochemical method. The assays of clone numbers counting and MTT were used to compare the different proliferation ability of PGCs from the 11.5 dpc and 12.5 dpc embryos. The effects of expanding PGCs from 11.5 dpc and 12.5 dpc embryos by those two ways above were compared. The EG clones were analyzed by the expression of alkaline phosphatase and the immunologic marker SSEA-1,the undifferentiated marker Nanog and the differentiation ability in vitro were also tested. RESULTS:①The formation ratio of primary and the first passaged EG clone from 11.5 and 12.5 dpc embryos was higher than that from 8.5 to 10.5 dpc embryos and efficiency of expansion was increased (P 0.05). On the third day, the number of the primary EG clones from 11.5 dpc embryos was higher than that from 12.5 dpc embryos (P 0.05), but the two groups had different characteristics. ④The EG clones have representative morphology with high level of alkaline phosphatase activity and SSEA-1, Nanog expression, which can differentiate into the cystic embryoid body. CONCLUSION: 11.5 dpc and 12.5 dpc mouse embryos, especially 11.5 dpc embryos are the optional time points to expand PGCs efficiently. Co-culturing with the tissue and isolating the gonadal ridges both of these two ways are practicable.

AIM: To study the effect of genistein on c-myc mRNA expression induced by oxidized low density lipoprotein (ox-LDL) in human vascular endothelial cells (ECV304). METHODS: LDL were isolated from healthy human plasma by gradient ultracentrifugation and oxidized by CuSO4. ECV304 cells were exposed to ox-LDL 200 mg*L-1 in the presence or absence of genistein 100 μmol*L-1 for 1, 2, and 4 h in vitro. Northern blot was employed to measure c-myc mRNA levels of ECV304. RESULTS: In response to ox-LDL 200 mg*L-1, c-myc mRNA expression in ECV304 increased by 3 fold for 1h and 3.3 fold for 2 h and decreased below the control level at 4 h. Expressions of c-myc stimulated by ox-LDL in the presence of genistein 100 μmol*L-1 for 1 h and 2 h were separately 80 percent and 60 percent of that in the absence of genistein 100 μmol*L-1. CONCLUSION: Genistein can effectively inhibit c-myc mRNA expression in ECV304 induced by ox-LDL.
