ABSTRACT
Objective To explore the protective effect and mechanism of vitamin D combined with puerarin on liver fibrosis.Methods The rats were divided into normal control group (C),tetrachloromethone group (CCl4),vitamin D group (V),puerarin group(P) and vitamin D combined with puerarin group(V+P).After 8 weeks,the rats were sacrificed and blood and liver samples were collected.The level of blood hyaluronic acid(HA) was tested.The hydroxyproline(Hyp) level in the liver was measured.The liver paraffin sections were made and examined by the sirius red staining.The mRNA levels of collagen Ⅰ and collagen Ⅲ in the liver tissue were detected by RT-PCR,and the levels of NF-κB and TNF-α in the liver were detected by Western blot.Results The CCl4 group appeared obvious liver fibrosis.The liver fibrosis degree was significantly improved in the group V,P and V+P,the blood HA level and liver Hyp level were reduced.The mRNA levels of collagen Ⅰ and collagen Ⅲ as well as the protein levels of NF-κB and TNF-α in the liver were significantly decreased.Among them.The liver fibrosis improvement degree in the V+P group was most significant.Conclusion Vitamin D combined with puerarin can protect rat liver fibrosis induced by CCl4 and its mechanism may be related with reducing the activation of hepatic stellate cells(HSC) and decreasing the collagenous fibers secretion.
ABSTRACT
Objective To investigate the incidence of adverse drug reaction (ADR)in patients in a hospital,and evaluate ADR-related factors,so as to provide references for the prevention of ADR and reducing of risk factors in drug use. Methods 223 clinically reported ADR cases were collected from January 1,2011 to December 31,2011, patients'age,types and administration routes of drugs relating to ADR,and ADR-involved organs and systems were analyzed.Results Of 223 patients with ADR,211(94.62% )received intravenous drip,3 received intravenous injec-tion,2 received intramuscular inj ection,and 7 received oral administration. ADR mainly occurred within 1-30 mi-nutes after taking the medicines,39(17.49% )occurred within 1-4 minutes,45(20.18% )within 5-9 minutes,80 (35.87% )within 15-29 minutes. Of organ or system involved by ADR,skin and its appendage damages were com-mon (93 cases),followed by gastrointestinal tract (62 cases)and systemic damage (45 cases);single organ and sys-temic damage were most common (184 cases,82.51% ). 123 cases (55.16% )of ADR were caused by antimicrobial use,60 cases (26.91% )were induced by Chinese medicine injection;Of top 10 ADR-inducing medicines,7 were an-timicrobial agents and 3 were traditional Chinese medicine injections,levofloxacin lactate and sodium chloride injec-tion ranked first(23 cases,10.31% ).Conclusion The occurrence of ADR is related to multiple factors,reporting and surveillance of ADR should be strengthened,the use of antimicrobial agents and traditional Chinese medicine should be rational,thereby reduce the occurrence of ADR.
