ABSTRACT
Objective To study the pharmacokinetics of raltitrexed using different ways of drug delivery, including femoral venous infusion, hepatic artery perfusion, hepatic artery injection of lipiodol suspension, hepatic artery perfusion followed by embolization with Gelfoam. Methods According to the administration way of raltitrexed, a total of 40 New Zealand rabbit models with VX2 liver tumor were randomly divided into group A (femoral venous perfusion), group B (hepatic arterial perfusion), group C (hepatic artery injection of lipiodol suspension), and group D(hepatic artery perfusion followed by embolization with Gelfoam). Drug concentration in plasma were determined by using LC-MS/MS method and the pharmacokinetic parameters were calculated. Results After administration of raltitrexed, the Tmax was 5 minutes in all 4 groups. In group A, B, C and D, the values were (5.88±1.39), (7.31±2.60), (9.86±5.10) and (7.19±2.27) respectively, with group C having the longest t1/2 value, which was significantly different with that of group A (P＜0.05); the (ng·ml-1·h-1) values were (2 056.40± 139.17), (1 389.21±180.28), (911.84±105.62) and (1 133.41±181.42)respectively, with the value of group A being obviously higher than that of group B, C and D (P＜0.05) and the value of group C being the lowest; the AUC0-t(ng· ml-1·h-1) values were (5 482.72±1 007.07), (4 156.99±1 475.77), (2 785.13±1 107.36) and (3 903.64±947.25) respectively, with the value of group A being remarkably higher than that of group B, C and D (P＜0.05) and the value of group C being the lowest. Conclusion Compared with the femoral vein infusion way, the ways of hepatic artery infusion, hepatic artery lipiodol suspension injection and hepatic artery perfusion followed by embolization with Gelfoam may promote more raltitrexed to deposit in the tumor area, thus, the curative effect is enhanced, the drug concentration in plasma is lowered and the side effects are alleviated.
ABSTRACT
Objective To evaluate the clinical effect of the transurethral resection of the prostate (TURP) reserving anterior lobe of the prostate .Methods A total of 736 cases of benign prostatic hyperplasia (BPH ) patients from Guizhou Aerospace Hospital were averagely randomly divided into the observation group and control group .Control group was treated with traditional TURP with the anterior lobe reseated ;while observation group was treated with the similar method to the control group ,but retained the anterior lobe .The clinical therapeutic effects and postoperative complications were observed .Results The maximum flow rate ,re-sidual urine volume and the international prostate symptom score in observation group did not show any statistical significance com -pared with that in control group after surgery (P> 0 .05) .The prevalence rate of temporary incontinence in observation group (1 .09% ) was lower than that in control group(5 .16% ) ,with significant difference(P0 .05) .Conclusion TURP reserving the anterior lobe can effectively reduce the incidence of temporary urinary incontinence ,there-fore ,this method could be spread in the clinical practice .
ABSTRACT
OBJECTIVE:To investigate the distribution and drug resistance of High-level Aminoglycoside Resistance Enterococcus spp (HLAR) in hospital infection. METHODS:The clinical specimens collected from 2004 to 2007 in our hospital were isolated by routine method. Identification of the bacteria and Antimicrobial susceptibility test were performed using automatic microbiology analysis system. RESULTS:Of the total 292 strains of Enterococcus which induced HLAR in hospital infection,Enterococcus faecalis (E.faecalis) represented 49.3% (144/292) and Enterococcus faecium (E.faecium) 41.4% (121/292). 27.4% (80/292) were from intensive care unit,17.5% (51/292) the department of nephrology and 8.9% (26/292) the neurosurgery department. The urinary system infection represented 29.8% (87/292) in hospital infection. The antimicrobial resistance of E.faecium was significantly higher than that of E.faecalis against quinolones and ?-lactamase antibiotics,but the antimicrobial resistance of E. faecalis was higher than that of E,faecium(P
ABSTRACT
OBJECTIVE:To optimize the water extraction process for Shenshu yangwei capsule.METHODS:The decoction conditions were optimized by orthogonal design with table L9(34)taking the yield of Hesperidin as index.RESULTS:The optimal watering extraction conditions of Shenshu yangwei capsule were as follows:adding 8 times amount of water,then extracting for 3 times with 1 h for each time.CONCLUSION:The water extraction technology of Hesperidin is simple,with complete extraction and high yield of Hesperidin,thus applicable for industrialized large-scale production.
ABSTRACT
OBJECTIVE: To establish a new pattern of ward round record for clinical pharmacist and rational use of drug. METHODS: The new pattern of ward round record was established according to domestic and foreign history pattern, The Principle and Proposed Pattern of Clinical Medication History in China, disease course record. This new pattern focused on patients’ disease and medication changes. A case of cardiovascular department was taken as example. RESULTS: Established ward around record contained two parts, i.e. first page and record chart. CONCLUSION: Established pattern is concise and practical and covers essential medical information. It makes communication more easily between pharmacist and doctors and meets the needs of clinical pharmacy practice.
ABSTRACT
To investigate the effect of Jianpiyiqi prescription on the expression of heat shock proteins (HSPs) and the changes of HSPs in gastric-ulcerated rats, the rat model of chronic gastric ulcer was induced by acetic acid. The SABC immunohistochemical method was used to observe HSP70 of mucosa around the gastric ulcer. Imaging analysis was performed. Western dot blot was used to detect HSPs contents in the plasma and gastric mucosal homogenate in each group. The results showed that HSP70 contents of the mucosa around the gastric ulcer in the model group and ranitidine-treated group were increased as compared with control group (P<0.01). Jianpiyiqi could increase the expression of HSP70 of the mucosa around the gastric ulcer further as compared with that in the model group and ranitidine-treated group (P<0.01). The HSP70 contents in the serum and mucosa in the model group and ranitidine-treated group were increased as compared with control group (P<0.01, P<0.05 respectively). HSP70 of serum and mucosa in the Jianpiyiqi-treated group was higher than in the model group and ranitidine-treated group (P<0.05, P<0.01 respectively).It was concluded that HSP might play a role in the process of pathophysiology of gastric ulcer. Jianpiyiqi could enhance gastric ulcer-healing through the protective mechanism of HSPs.
