BACKGROUND:In vitro experiments suggest that LIM mineralization protein-1 (LMP-1) gene can increase the expression of LMP-1 protein in osteoporotic bone marrow mesenchymal stem cells. OBJECTIVE:To investigate the LMP-1 expression in osteoporotic bone marrow mesenchymal stem cells transfected with RV-LMP-1-GFP in vitro. METHODS:Twelve SD female rats were selected and subjected to bilateral ovariectomy for establishment of osteoporosis models. After 2 months of feeding, bilateral femurs, tibiae, and humeri of rats were taken to isolate and culture bone marrow mesenchymal stem cells. Passage 3 cells were taken and randomly divided into ovariectomized group and LMP-1 transfection group. Another six rats only underwent removal of the same amount of fat tissue around the ovary, and passage 3 cells which were harvested as those in the former two groups served as sham group. RT-PCR and western blot assay were performed to determine the expression of LMP-1 protein and mRNA. RESULTS AND CONCLUSION:Under an inverted fluorescence microscope, transfected bone marrow mesenchymal stem cells from osteoporotic rats showed green fluorescent expression. The three groups al could express LMP-1 at the protein and mRNA levels. The expression levels of LMP-1 protein and mRNA in the LMP-1 transfection group were significantly higher than those in the ovariectomized group and sham group (P<0.05), but there was no statistical difference between the latter two groups (P>0.05). The successful expression of the RV-LMP-1-GFP gene in osteoporotic SD rat bone marrow mesenchymal stem cells was realized at the protein and mRNA levels;moreover, the expression of LMP-1 was increased dramatical y. These findings indicate that LMP-1 gene is successful y transferred into osteoporotic SD rat bone marrow mesenchymal stem cells, and significantly elevates the expression of LMP-1 mRNA and protein.

OBJECTIVE:To investigate the characteristics and regulation of antibiotics-induced ADR in our hospital and ex-plore effective prevention measures,in order to provide reference for safe and rational use of antibiotics in the clinic. METHODS:111 antiobiotics-induced ADR reports were collected from our hospital during 2012-2014,and analyzed in terms of patient’s gender and age,route of administration,drug category,organs/systems involved in ADR,etc. RESULTS:The patients aged <10 years old and >60 years old took up the highest proportion,accounting for 27.93% and 25.23%,espectively. ADR induced by intrave-nous route of administration had the highest incidence,accounting for 84.68%;cephalosporins-induced ADR was the most,account-ing for 26.13%;lesion of skin and its appendents was main antibiotics-induced ADR,accounting for 44.92%. CONCLUSIONS:Clinical pharmacists should provide technical support to doctors and nurses to aviod the occurrence of ADR.

Objective To investigate the relationship between blood concentration of sodium valproate and the anti‐epileptic effect and the influencing factors of blood concentration of sodium valproate ,and to provide evidence for clinical individual adminis‐tration .Methods The blood concentrations of 133 cases of patients treated with sodium valproate were determined in the affiliated Yongchuan hospital of Chongqing medical university ,the monitoring results of blood concentration were statistically analyzed ,and the anti‐epileptic effect of 133 cases of patients were observed and analyzed .Results The epilepsy of 80 cases of patients were con‐trolled ,accounted for 60 .15% of the total number;in the 69 cases of patients within the effective blood drug concentration (50-100 mg/L) ,the epilepsy of 51 cases of patients were controlled ,accounting for 38 .35% .In the 44 cases of patients whose blood drug concentration were less than 50mg/L ,the epilepsy of 26 cases of patients were not controlled .The distribution of blood concentra‐tion between men and women were similar .The blood concentrations among each age group were different ,the blood concentrations of 52 .87% patients in the adult group were below or above therapeutic range that were 39 .13% in the minor group .The adverse reactions were increase with the increase of blood concentration .Conclusion There are differences between the blood concentrations of sodium valproate and clinical effect ,the reasonable individual administration should be conducted according to the patient′s blood concentrations of sodium valproate ,the epilepsy control situation of patients and the patients′age .

The regulatory effect of CD3 McAb on the human fetal thymocyte proliferative response toTPA was investigated.It was shown that the CD3 McAb couldn't induce human fetal thymo-cyte proliferative response,but suppressed PHA-induced human fetal thymocyte proliferativeresponse and promoted TPA-induced proliferative response,in a dose dependent manner.Ex-ogenous rHuIL—2,but not rHuIL—1 ,could enhance the proliferative response to CD3 McAb.These results have significances for understanding the expression of CD3 antigen and it's func-tions.
