ABSTRACT
Objective To make the chromosome karyotype analysis of 130 patients with leukemia by using the improved chromosome short-term culture method.Methods We optimized the main factors with a single factor gradient experiment in short-term culture of bone marrow chromosome, including colchicines concentration, duration of action of colchicines,and hypotonic time.On this basis,we conducted the three-factors and three-level orthogonal experiment to achieve improved bone marrow chromosome preparation system,which was later applied in 130 patients with leukemia in our hospital.Results The orthogonal experiment results showed that the optimum conditions were colchicines concentration of 0.07 μg/mL,colchicines action time of 80 min,and hypotonic time of 35 min during the preparation of the bone marrow chromosome.Using this method,the chromosome preparation success rate reached 97.69% and the detection rate of abnormal karyotype reached 82.3% in the chromosome karyotype analysis.Conclusion Bone marrow chromosome preparation system with colchicines concentration of 0.07 μg/mL and colchicines action time of 80 min,and hypotonic time of 35 min is worthy of clinical promotion.
ABSTRACT
Objective To investigate the therapeutic effect of quercetin on acute gouty arthritis and its influence in re-nal function in rats. Methods Seventy male Sprague-Dawley rats were randomly divided into normal control group, model group, colchicine group (0.5 mg/kg), allopurinol group (20 mg/kg), quercetin 100, 200 and 400 mg/kg groups (n=10 for each group). Rats were administered various drugs by oral gavage once a day for seven consecutive days throughout the experi-ment. On the fifth day, the animal model of acute arthritis was set up by giving monosodium urate crystal combined with hypo-xanthine. The inflammatory reaction was detected by measuring the circumference of right hind leg anklejoint with a tie line method at 0, 2, 6, 12, 24 and 48 h. The swelling ratio was calculated. The serum levels of uric acid (UA),β2-microglobulin (β2-MG), cystatin C (Cys-C), urea nitrogen (Urea) and creatinine (Cr) were detected by colorimetry and enzyme-linked im-munosorbent assay.Rats were sacrificed at the end of experiment, and the kidney was weighed and the renal index was calcu-lated. Results Treatment with quercetin, colchicine or allopurinol can significantly attenuate swelling rate in rats of acute gouty arthritis. The serum levels of UA were significantly higher in colchicine group and quercetin group than those of nor-mal control group and allopurinol group. The serum levels of UA was significantly lower in allopurinol group than that of nor-mal control group. After 48-h modeling, there was no significant difference in serum UA level between seven groups except allopurinol group. The levels ofβ2-MG and Cys-C were the lowest in normal control group than those of other groups. The se-rum levels of Urea and Cr and renal index were the highest in allopurinol group compared with those of other groups ( P<0.05). Conclusion Quercetin shows a significant effect of anti-inflammatory on acute gouty arthritis in rats. The model es-tablishment may lead to different degrees of renal damage. Quercetin has no protective effect against renal injury, and allopu-rinol aggravates kidney injury.
ABSTRACT
Objective To explore the application of the ultraviolet spectrophotometry method in detecting colchicine poisoning serum to provide the basis for clinical diagnosis and treatment of colchicine poisoning.Methods 0.5 mL of serum was taken and added with the extract solution(chloroform∶methanol=95 ∶5)4.0 mL.The sufficient oscillation extraction and high-speed cen-trifugation were performed.Then the organic layer was taken into another test tube for drying by nitrogen.0.2 mL of methanol dis-solved residue was taken and blended.50 μL of the mixed solution was taken for conducting ultraviolet scanning.Results The max-imum absorption peak of serum colchicine was (351 ±1)nm,the concentration within 5.0-40 μg/mL showed linearity,the regres-sion equation wasY =0.050 2X +0.001 3,the correlation coefficient was 0.999 5,the recovery rate was 83.8% -102.8%,the rel-ative standard deviation:3.3% -4.8%.The intra-day and inter-day were 3.22%-4.74% and 3.45%-4.66%,the lowest detec-tion concentration was 1 .0 μg/mL.Conclusion This method is simple to operate,fast in analysis,accurate in the detection result, which provides a simple and accurate detection method for clinical diagnosis of colchicine poisoning.
ABSTRACT
Objective To observe the clinical effect of small dose of colchicine combined with glucocorticoid for acute gouty arthritis. Methods Ninety-two patients with acute gouty arthritis were equally and randomly divided into small doses of colchicine combined with dexamethasone treatment group (treatment group) and conventional large dose colchicine treatment group (control group) between January 2009 and December 2013. The articular lesion scoring and clinical efficacy evaluation were performed at 3, 6, 12, 24, 48, and 72h after treatment. Erythrocyte sedimentation rate (ESR), white blood cells, hepatorenal function and glomerular filtration rate (GFR) were determined before and 72h after treatment respectively. The gastrointestinal adverse events and recurrence rate were observed within one month after treatment. Results The articular lesion scores were significantly decreased at 6, 12, 48, and 72h after treatment in treatment group compared with control group (P0.05). Serum uric acid, glutamic-pyruvic transaminase in serum (SGPT), and GFR did not show any change before and 72h after the treatment, and there was also no significant difference between groups (P>0.05). The incidence of gastrointestinal adverse events were obviously higher in control group (76.1%) compared with that of the treatment group (P<0.05), and the differences was statistically significant. There was no statistical difference in recurrence rate between the control group and treatment group after a follow-up of one month. Conclusions Compared with conventional large dose colchicine, small dose of colchicine combined with dexamethasone can more rapidly and effectively control acute gouty arthritis, with good tolerability and safety, thus being worthy of popularization clinically.
ABSTRACT
OBJECTIVE:To observe the therapeutic effect of pagosid in treating acute gouty arthritis.METHODS:70pa-tients were randomly assigned to treatment with pagosid(treatment group)or colchicine(control group),the onset time of therapeutic effect,symptom amelioration,blood uric acid descending level and adverse drug reactions of the two groups were monitored.RESULTS:There were ameliorated clinical symptoms in both groups;however,the blood uric acid level of the treatment group were reduced,and little adverse reaction involved in this group and the onset of curative effects was slow,which stood at(65.78?30.19)hours.CONCLUSION:Treatment of acute gouty arthritis with pagosid ameliorates hyper-uricemia and mitigates pain and swelling accepted by patients better.
ABSTRACT
Behcet's disease is a multisystematic inflammatory disorder affecting eyes. Visual loss is the most serious effect of Behcet's disease with posterior segment involvement.Because of the disorder's devastating visual consequences, its treatment has received considerable attention.Since the treatment of Behcet's disease has often been unsatisfactory, many different types of treatment have been attempted. We retrospectively reviewed the charts of 28 patients with severe ocular Behcet's disease involving posterior segment.The patients with posterior segment involvement were initially treated with triple regimen (corticosteroid, colchicines, and azathioprine).If intraocular inflammation does not resolve or the inflammatory process recurs, combination with low doses of cyclosporine should be considered (quadruple therapy).Over the course of therapy, visual acuity improved in 25 of 51 eyes (49.01%), remained stable in 14 of 51 eyes (27.45%), and declined in 12 of 51 eyes (23.52%).It improved or maintained the visual acuity in 39 of 51 eyes.There were no serious side effects attributable to triple or quadruple therapy that required withdrawal. The use of corticosteroids, colchicines, azathioprine, and cyclosporine may improve therapeutic efficacy and limit the adverse drug effects, and this combination method appears to be an effective treatment for the ocular complications of Behcet's disease.
