ABSTRACT
OBJECTIVE:To observe therapeutic efficacy of Jiangu tongxiao pills in the treatment of osteoarthritis. METH-ODS:72 patients with osteoarthritis were randomly divided into treatment group and control group with 36 cases in each group. Treatment group was given Jiangu tongxiao pill orally,5 g/time,3 times/d;control group was treated with Glucosamine sulfate capsules orally. 0.5 g/time,3 times/d. A treatment course lasted for 7 days,and both group received 4 treatment courses. Clinical ef-ficacy,WOMAC score and VAS score were observed and compared between 2 groups. RESULTS:The total effective rate of treat-ment group(94.44%)was obviously superior to that(83.33%)of control group,with statistical significance(P<0.05). WOMAC score and VAS score of treatment group were lower than those of control group,with statistical significance(P<0.05). CONCLU-SIONS:Jiangu tongxiao pills has good therapeutic efficacy for osteoarthritis.
ABSTRACT
Objective To compare the sensitivity and specificity of venereal disease research laboratory (VDRL) test versus several other laboratory tests in the diagnosis of neurosyphilis. Methods Lumber puncture was conducted to obtain cerebrospinal fluid (CSF) from untreated outpatients with latent syphilis (LS) or serofast outpatients with LS. Then, VDRL test, rapid plasma regain (RPR) test, Treponema pallidum particle agglutination (TPPA) assay, fluorescent treponemal antibody-absorption (FTA-ABS) test and protein quantification were performed on these CSF samples. The sensitivity, specificity, positive predictive value and negative predictive value were compared between VDRL test and four other laboratory tests in the diagnosis of neurosyphilis. Results Totally, 61 cases of latent syphilis were included in this study. The sensitivity, specificity,positive predictive value and negative predictive value were 93.44% (57/61), 99.32%(293/295), 96.61%(57/59), 98.65% (293/297)for CSF-RPR, respectively, 91.80% (56/61), 82.71% (244/295), 52.34% (56/107),97.99 (244/249) for CSF-TPPA, respectively, 93.44% (57/61), 82.71% (244/295), 52.78%(57/108), 98.39%(244/248) for CSF-FTA-ABS, respectively, and 49.18%(30/61), 97.29% (287/295), 78.95% (30/38),90.25% (287/318) for CSF protein quantification, respectively. Conclusions CSF-VDRL cannot be replaced by CSF-RPR, -TPPA, -FTA-ABS, or CSF protein quantification in the diagnosis of neurosyphilis. CSF-RPR shows a high sensitivity and specificity in the diagnosis of neurosyphilis, with an increased diagnostic capability (area under the receiver operating characteristic curve) compared with CSF-TPPA, CSF-FTA-ABS or CSF protein quantification.
ABSTRACT
<p><b>OBJECTIVE</b>To study the cytotoxicity of maitotoxin (MTX) and its protective effects on calcium-channel blocking agents, so as to provide the data for control and treatment of MTX poisoning.</p><p><b>METHODS</b>Cytotoxicity was measured by MTT detecting system, and cytoplasmic free [Ca(2+)]i was measured by F-4500 fluorometry.</p><p><b>RESULTS</b>Incubation with 8 ng/ml MTX for 3 h reduced the survival ratio of LLC-PK(1) cells. The response was found in a time- and concentration-dependent manner, with significant differences as compared with the control group. The MTX-induced increase in [Ca(2+)]i was inhibited by Verapamil and Nifedipine at 5 x 10(-5) mol/L and 1 x 10(-4) mol/L respectively. Both of them significantly reduced the death of the LLC-PK(1) cells.</p><p><b>CONCLUSIONS</b>Cytotoxicity of MTX may be caused by the elevated intracellular [Ca(2+)]i. Calcium-channel blocking agents could protect LLC-PK(1) cells from injury by MTX.</p>
