ABSTRACT

Objective: Fufang Biejia Ruangan Tablet (FBRT) is widely used for the treatment of liver fibrosis. However, Hominis Placenta (HP), as an important adjuvant of FBRT, has been restricted for medicinal using due to the limited availability, ethical controversy and safety issues. The present study aimed to investigate the therapeutic effects of novel FBRT (N-FBRT) with sheep placenta (SP) as substitute for HP on liver fibrosis and explore its possible mechanisms. Different dosages of SP in N-FBRT were also evaluated. Methods: Rats were subcutaneously injected with CCl

ABSTRACT

Type Ⅰ sialidosis is a neurosomatic disorder related to the storage of lysosomal and induced by shortage of neuraminidase. It is an autosomal recessive disorder, maybe heterogeneous in its onset, clinical manifestations and prognosis. A case of type Ⅰ sialidosis with a missense mutation in the α-N-acetyl-neuraminidase (NEU1) gene is reported. The patient was characterized by reduced visual acuity, ataxia and subcortical myoclonus. Although the macular cherry red spots were not detected in the male patient, his bilateral visual evoked potential showed severely prolonged latencies of P100, which was consistent with continuous decline of his visions. Finally, he was treated with carbamazepine and clonazepam with moderate improvement in the symptom of myoclonus. In order to make the definite diagnosis, the importance of a clinical history integrating all the patient′s clinical manifestations and the mutation in NEU1 gene was highlighted. Regardless of being an uncommon disorder, the burden for those patients with sialidosis was significant. Therefore, this diagnosis in the relevant setting should always be considered.

ABSTRACT

Objective To establish nasopharyngeal carcinoma cell line (CNE1) with eIF1 gene stable over-expression and to study its effects on the proliferation and migration of nasopharyngeal carcinoma cells.Methods EIF1 over-expression vector was constructed by adopting the pEGFPC1 eukaryotic expression system for transfecting nasopharyngeal carcinoma CNE1 cells.Thus the stably transfected EIF1-elF1 and its control cells were obtained.The over-expression situation of eIF1 in these cells was verified by real time fluorescence quantitative PCR(qPCR) and Western blot.The proliferation and migration activity of CNE1-eIF1 cells were tested by adopting the cell proliferation and migration tests.Results The enzyme digestion electrophoresis identification and sequencing showed that the pEGFPC1-eIF1 eukaryotic expression vector was successfully constructed.After mRNA and protein expression identification,compared with the reloading plasmid transfection group,the eIF1 gene mRNA and protein expression levels in nasopharyngeal carcinoma cell line CNE1 stably over-expressing eIF1 were up-regulated by 2.85 folds and 2.58 folds respectively (P< 0.05),while its proliferation and migration activities were down-regulated by 55 % and 36 % respective (P< 0.05).Conclusion The nasopharyngeal carcinoma cell line over-expressing elF1 is successfully constructed,the eIF 1 over-expression could significantly down-regulate the proliferation and migration activities of nasopharyngeal carcinoma cells,suggesting that eIF1 has potential anti-tumor effect.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of refining temperatures and amounts of sheep's oil used in processing Epimedii Folium on Kedney-yang deficiency rats.</p><p><b>METHOD</b>The corticosterone was subcutaneous injected to establish the kidney yang deficiency rat model. With the temperatures and amounts of sheep's oil were 250 degrees C/30%, 120 degrees C/30% and 120 degrees C/20% respectively, the crude drug and three kinds of pressed Epimedii Folium were extracted by water and used as examined samples while total flavonoid of Epimedii Folium was used as positive control. After examined samples and control samples were intragastirc administrated, the pharmacologic action was analyzed.</p><p><b>RESULT</b>As compared to crude drug, all of the aqueous extracts of processed Epimedii Folium have stronger effect of warming kidney and enhancing yang, especially the Epimedii Folium processed by sheep's oil with refining temperatures 120 degrees C and amounts of sheep's oil 30%. Its mechanism might be related to improving the insufficiency of hypothalamic-pituitary-adrenal-thymus (HPAT) axis suppression.</p><p><b>CONCLUSION</b>The refining temperature of sheep's oil can affect the quality of excipients and processed drugs. The results may be useful in explaining the mechanism of Epimedii Folium processing and establishment of pharmaceutical standard of sheep's oil used as processing excipients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the anaphylaxis and hemocytolysis of 6 kinds of tween-80 injection from different source.</p><p><b>METHOD</b>The Hartley albinism guinea pig was used to carry on the active systematic anaphylaxis (ASA) and the passive cutaneous anaphylaxis (PCA). The in vitro hemolytic experiment and the hemocytolysis was observed by means of spectrophotometry on the domestic rabbit.</p><p><b>RESULT</b>The result of ASA and PLA of 6 kinds of tween-80 injection from different source assumed the negative. In observation time, the temolysis rate of 3 kinds of tween-80 injection are more than 5%, while the others are also more than 5% only in the highly concentrated test tube.</p><p><b>CONCLUSION</b>Six kinds of tween-80 injection from different source have not caused the immune-mediated anaphylaxis, but it may have hematolysis tendency on intravenous injection. The hemocytolysis of tween-80 may not be entirely caused by the impurities. It is worthy of further study that the physical and chemical properties of the product itself and the undeserved concentration is doubtful whether there is also some internal relations with the generation of hemolytic.</p>
