Objective To culture human pituitary adenoma cells to provide some useful experimental foundations to practice pituitary adenoma cells as donor cells in the extracranial implantation. Methods Human pituitary adenoma cells obtained by operation were cultured in vitro, and their growth state was dynamically observed. Immunohistochemical staining and RIA were used to evaluate their functional status. Results The cultured pituitary adenoma cells still had secretory function in vitro. 6 cases of GH adenoma cells secreted a large amount of GH, 5 cases of PRL adenoma cells secreted a large amount of PRL, and 3 cases of pituitary adenoma cells without function could also secrete a small quantity of FSH, LH and PRL. Conclusion 14 cases of cultured human pituitary adenoma cells had secretory function in vitro, which provides the useful experimental data to perform extracranial implantation with pituitary adenoma cells as donor cells.

OBJECTIVE:To optimize the formula of piribedil hydrochloride orally disintegrating tablets and to investigate their related indexes.METHODS:Taking the contents of crospovidone(PVP XL)(disintegrating agent),amylum pregelatinisatum(loading agent) and Gum Acacia(glidant) as factors,the disintegrating time(td),the wet time(t) and the suspend stability(?A) as the evaluate indexes to carry on the orthogonal experimental to optimize the formula.The dissolution curve of the optimized formula was drawn.RESULTS:The optimized formula for the piribedil hydrochloride orally disintegrating tablets were as follows:the contents of crospovidone(PVP XL),amylum pregelatinisatum and Gum Acacia were 15%,20%,and 15% respectively.The prepared orally disintegrating tablets disintegrated completely within 30s and dissolved basically within 2min.CONCLUSION:The prepared preparation can meet the related standards specified of China Pharmacopeia.

Partial immunoactivities of peptidoglycan(PG)isolated from lactic acid bacteria were investigated.PG isolated from strain Z8 and Z17 of lactic acid bacteria respectively,had similar immunoactivities.The phagocytic function of M?(macrophage)increased markedly and serum lysozyme activity was significantly enhanced by injection of PG-extracts on mice.Investigation of immuno-enhancing effects of PG on vaccine of Newcastle disease in chickens showed that the hemagglutination inhibition levels of PG were higher than that of the control and the level was maintained for a longer time as compared to the control.

Based on the analysis of current condition of local medical schools and medi-cal talents demand at the grassroots level,this paper indicates that,taking students’personality development as a breakthrough point,with practice platform construction as main part,supple-mented by multi-knowledge hierarchy and scientific and cultural exposure,backed by workable policy.

Inflammation is a defensive reaction and the most common pathological manifestation of dry eye.In addition,excessive inflammatory response is considered to be the most common pathogenic factor and main cause of dry eye.Currently,the active mechanism of anti-inflammatory drugs has been well-known,and topical antiinflammatory therapy for dry eye is exerting a role at certain extend.However,some adverse responses of these drugs are emerging during the treating procedure.Therefore,it is emphasized that a large sample size of and multicenter randomized-controlled clinical trial is needed to identify the different effects of various anti-inflammatory drugs for different types of dry eye diseases,which will offer a basis for standardized anti-inflammatory treatment for dry eye.

Objective To observe the long term effects of triancinolone acetonide(T-A)as a substitution for prednisone,a maintenance therapy in treating children with nephrotic syndrome(NS).Methods Twenty-five children with idiopathic NS(10 children with simple type NS and 15 children with nephritic type NS).Prednisone treatment for 4-8 weeks would bring remission,and immunosupression was added if remission failed.Then oral prednisone was reduced to 2 mg/kg per alternate day for 2 weeks,followed by a small dose of T-A(0.5-1.0 mg/kg)intramuscular injection,once a year per month for the first year,and every other month for the second year,as for the 8 frequently relapse cases,it would be every 3 months for the third year,other 17 cases stopped T-A intramuscular injection in the third year.Two weeks after T-A treatment stopped using prednisone.The relapse and the side-effects was observed through the observation of 25 NS children's clinical manifestation,routine urine test,and biochemistry variation before and during the T-A treatment,along with a 6 to 10 years follow-up survey after T-A therapy stopped.Statistical analysis was performed by using SPSS 10.0 software.Results 1.Median dose of T-A was 0.97 mg/kg per time,total doses of T-A was 18.1 mg/kg(13.5-24.4 mg/kg).2.There were 16 relapse cases by prednisone treatment,while 7 relapse cases by T-A treatment for 2 years,there existed a significant comparison(P0.05).4.There were only 4 relapsed cases in the 6-10 years of follow-up observation,the difference was sharp compared with the 16 relapsed cases before T-A treatment(P

Objective:To explore the curative effect of acupuncture combined with huanglian wendan decoction on the mild cognitive impairment after stroke.Methods:100 patients with mild cognitive impairment after stroke were enrolled in our hospital from June 2013 to August 2016 and randomly divided into two groups.The control group (n=50) accepted nimodipine,and the study group (n=50)accepted huanglian wendan decoction combined with acupuncture treatment based on the control group.The MMSE and MSSS scores were evaluated and compared,and the improvement of cognitive dysfunction and nervous dysfunction,quality of life were compared and analyzed.Results:After treatment,the MMSE,ADL scores of patients were remarkably decreased compared with those before treatment (P＜0.05),and the decreasing degree of study group was significantly higher than those of the control group (P＜0.05).The MSSS,MBI scores of both groups were significantly increased compared with those before treatment (P＜0.05),and the increasing degree of study group was significantly higher than those of the control group (P＜0.05).The effective rates of improvement in cognitive dysfunction and nervous dysfunction,quality of life of study group were significantly higher than those of the control group (P＜0.05).Conclusions:Huanglian wendan decoction combined with acupuncture treatment was effective for the mild cognitive impairment after stroke and could improve the quality of life.

AIM: To investigate the inhibitory effect of vector-based RNA interference(RNAi) on the expression of melanoma associated antigen A3(MAGEA3) protein in hepatocellular carcinoma cells and on apotposis of hepatocellular carcinoma cells.METHODS: A vector for transcribing specific small hairpin RNA(shRNA) targeting MAGEA3 gene was constructed,introduced into hepatocellular carcinoma MEL-ED1 cells by Lipofectamine 2000.The MAGEA3 protein and mRNA expression levels of MEL-ED1 cells were detected by Western blotting and RT-PCR, respectively.The cell apoptosis was studied by DNA fragmentation,electron microscopy,TUNEL assay,and annexin V/PI staining.RESULTS: The vector of RNA interference was successfully constructed and MAGEA3 expression was descreased significantly in MEL-ED1 cells.After the shRNA expression vector was transfected into the MEL-ED1 cells,the expression of MAGEA3 gene was inhibited significantly(by 90%).DNA fragmentation,electron microscopy and TUNEL assay showed classic apoptosis characters in the MEL-ED1 cells transfected with pSilencer-MAGEA3 plasmid with an apoptosis rate of 21.41% ?1.98%,significantly higher than those in the negative control group transfected with pSilencer-neo and in the non-transfected group(both P
