Objective To evaluate the clinical efficacy of the bipolar plasmakinetic system in transurethral resection for bladder tumors (TURBt). Methods 57 patients aged 38 to 82 (42 male and 15 female; mean age, 58.2 years) with bladder tumors were treated by the bipolar plasmakinetic system. Single tumor was noted in 38 patients and multiple tumors in 19. Results All the patients received only one TURBt. The mean operation time was 22 min and mean hospital stay was( 5 ± 0.36 )days. 55 patients were followed up and 2 were lost. 12 patients relapsed within 24 months of follow-up. 8 had to receive second transurethral resection and 4 required radical cystectomy. Conclusions The bipolar plasmakinetic system in TURBt is minimally invasive, effective and safe. 相似文献

Forty-four cases of
benign prostate hyperplasia were underwent using transurethral electrovaporization of
prostate (TUVP). The average age of the patients was 71.3,and the mean operation time
was 55min. The mean indwelling catheter time was 54h, capable of voiding fredy after the
removal of the catheter. International prostate symptom score(I-PSS) dropped from 28.9
before the procedure to 7.2 postoperatively. Qmax increased from 4.9ml/s to
18.3ml/s. Neither transurethral resection syndrome nor severe bleeding occurred in the
patients. TUVP was daimed to be effective and safe with less bleeding and few
complications and less trauma to the patients 相似文献

Summary The single-dose plasma kinetics of diflunisal was studied in healthy young and old subjects, in patients with rheumatoid arthritis,
and in patients with renal failure. The plasma and urine kinetics of the glucuronidated metabolites of diflunisal were studied
in the healthy elderly subjects and in the patients with renal failure. In addition, the multiple-dose plasma kinetics of
diflunisal was assessed in healthy volunteers and in patients with rheumatoid arthritis.
After a single dose of diflunisal the terminal plasma half-life, mean residence time and apparent volume of distribution were
higher in elderly subjects than in young adults. No difference was observed in any pharmacokinetic parameter between age-matched
healthy subjects and patients with rheumatoid arthritis.
The elimination half-life of unchanged diflunisal was correlated with the creatinine clearance (r=+0.89) and its apparent total body clearance exhibited linear dependence on creatinine clearance (r=+0.78).
In patients with renal failure, the terminal plasma half-life and mean residence time of diflunisal were prolonged. The renal
and apparent total body clearances were lower, the mean apparent volume of distribution was higher and the mean area under
the concentration-time curve extrapolated to infinity (AUC) was greater in the renal failure patients than in controls.
The plasma concentration of the glucuronidated metabolites rapidly rose to levels above those of unchanged drug in renal patients,
whereas they were lower than those of unchanged diflunisal in controls. The AUC (0–96 h) of diflunisal glucuronides in the
patients was four-times that in controls, and the terminal elimination half-life of the glucuronides was prolonged in them.
The renal excretion and clearance of diflunisal glucuronides were reduced when renal function was impaired.
After multiple dosing, the pre-dose steady-state plasma-concentration increased with decreasing creatinine clearance (r=-0.79). When the plasma concentration exceeded 200 μmol·1−1, the elimination half-life was doubled, due to partial saturation of diflunisal conjugation. This finding suggests that lower
doses could be used in long-term treatment.
Thus, old age and arthritic disease appear to have little influence on the kinetics of diflunisal in the absence of renal
functional impairment. Ordinary doses can be given for short term treatment of elderly patients with or without RA. In patients
with renal failure, however, reduced doses of diflunisal are recommended. 相似文献

Rationale: Search for alternatives to lithium therapy for mood disorders commenced with anticonvulsants, carbamazepine (CBZ) and valproic
acid (VPA), in the late 1970s. The comparative safety and efficacy data of CBZ and VPA monotherapy in patients with bipolar
disorder remain to be established. Objectives: The main objectives of the study were to assess the relative anti-manic efficacy and safety of CBZ and VPA; to study the
feasibility of using either, as a first line anti-manic agent; to investigate and generate clinically relevant parameters
involving therapeutic drug monitoring of the two drugs. Methods: After a 2-day screening period, suitable patients (n=30) were randomly assigned to treatment with CBZ or VPA. Both the drugs were started with an average dose of approximately
20 mg/kg body weight per day. Further increment in dose was carried out at weekly intervals, guided by clinical improvement,
serum levels and treatment emergent adverse events. The primary efficacy measure in the protocol was defined as a change from
baseline to endpoint in total score on the Young Mania Rating Scale. A favourable clinical response was defined a priori as
a decrease of more than 50% from baseline in Young Mania Rating Scale total score. Results: Both CBZ and VPA were found to be efficacious as single first-line anti-manic agents, however VPA proved to be better. Using
the intent-to-treat analysis, the VPA group showed a significant fall in YMRS total scores after week 1 while the CBZ group
showed a significant fall after week 2. In the primary efficacy analysis, valproate group experienced significantly greater
mean improvement in Young Mania Rating Scale total score than the CBZ group. Of the VPA treated patients, 73% showed a favourable
clinical response while 53% of the patients on CBZ responded favourably. In the CBZ group, significantly more patients received
rescue medication during the week 2 and the requirement was quantitatively more as compared to the VPA group. The steady state
serum concentration (Css) of CBZ ranged from 3 to 9 μg/ml; however, it did not appear to correlate with the dose or clinical
response. The Css of VPA ranged from 50 to 100 μg/ml; a linear correlation was found between the dose and serum levels of
VPA as well as between weekly rise in serum levels and clinical response. Weekly dose escalations of VPA also correlated positively
with corresponding rise in serum levels. Significantly more patients in the CBZ group reported adverse events, including nausea,
vomiting and dizziness, than VPA. Conclusions: The findings from this study suggest that both CBZ and VPA monotherapy is feasible for treatment of acute mania; however,
VPA is more efficacious in terms of its early onset of action, lesser requirement for rescue medication and better tolerability.
Further work needs to be undertaken to characterise the manic patients in terms of their differential psychopharmacologic
response profile.

Summary The total and unbound plasma concentrations of phenprocoumon and the prothrombin complex activity were determined in 51 patients
on phenprocoumon.
A 7-fold difference in the dosing rate (10–70 μg/kg/day) was required to maintain the prothrombin complex activity at 11–30%
of normal. The variation in dosing requirement was mainly due to inter-individual differences in the intrinsic clearance of
phenprocoumon and only to a minor degree to differences in sensitivity to it.
On average patients with myocardial infarction required only 2/3 of the daily dose of phenprocoumon of post cardiac surgery
patients and patients with thrombosis and emboli. That difference appeared to be due to higher clearance in surgical patients
and to greater resistance to phenprocoumon in patients with thrombosis and emboli. The total clearance in patients varied
approximately 5-fold. It was better predicted by the interindividual intrinsic clearance (r=0.84) than by the unbound fraction (r=0.15). 相似文献

Objective This study aimed to determine the change of plasma endothelin (ET) in patients with diabetes meUitus .Methods 42 diabetic patients and 50 normal people were included in our study.The diabetic patients were divided into 2 groups, one group with vascular complications, and the other one without. The plasma ET, blood pressure,fasting blood glucose and other intems were measured in these people. Result The plasma ET level was found to be greatly elevated in diabetic patients comparing with the normal people and ET level of diabetic patients with vascular complication was much higher than patients without complications. The plasma ET level had positive correlation with systolic pressure in diabetic patients. Conclusion The result indicated that the high level of plasma ET might play an improtant role in the occurrence and development of vascular complication. The level of plasma ET should be routinely measured in diabetic patients. The patients with high - level plamsa ET should take therapeutic measures to prevent the occurrence of vascular complication. 相似文献
