ABSTRACT

OBJECTIVE To evaluate the efficacy, safety and cost-effectiveness of generic drugs and original drugs of voriconazole. METHODS The information of patients who used voriconazole generic drugs selected in National Centralized Drug Procurement (generic drug group) or non-selected original drugs (original drug group) in the treatment of fungal infection was collected from the our hospital. The propensity score matching was carried out to eliminate bias. The comprehensive efficacy was evaluated according to clinical efficacy, image findings and microbiological test, and stratified analysis of different populations was conducted based on fungal species, underlying diseases, etc., the efficacy of different stratifications was evaluated. Evaluation of safety was performed by using the incidence of adverse reactions. The total cost, defined daily doses (DDDs) and defined daily dose cost (DDDc) were used to evaluate the cost-effectiveness. RESULTS A total of 436 patients were included, and there were 190 patients in each group after matching. In terms of efficacy, the effective rates of voriconazole generic drugs and original drugs were 62.63% and 59.47% (P=0.528); in terms of safety, the incidence of adverse reactions caused by generic drugs and original drugs of voriconazole was 13.68% and 7.89%, respectively(P=0.069). In terms of cost-effectiveness, the average total cost of generic drugs was 4 636.26 yuan, and that of original drugs was 8 613.20 yuan (P<0.001). After the implementation of National Centralized Drug Procurement, replacement rate of generic drugs increased to 87.30%, and DDDc decreased by 59.08%. CONCLUSIONS The efficacy and safety of voriconazole generic drugs are similar to those of original drugs in the treatment of fungal infection, and it is more cost-effective in terms of treatment cost.

ABSTRACT

<p><b>OBJECTIVE</b>To study the mercury accumulation in injured skin rats induced by Badu Shengji San (BDSJS), a traditional Chinese medicine preparation for external use.</p><p><b>METHOD</b>Injured skin rats were treated with BDSJS for consecutively 4 weeks. During the 4 weeks and the following 4 weeks after the drug withdrawal, samples were collected for determining mercury contents in blood, urine and kidney, with urinary N-acetyl-beta-D-glucosaminidase(NAG) and beta2-microglobulin (beta2-MG) as indicators of renal toxicity and serum biochemical indicators of hepatic and renal functions. Additionally, activated partial thromboplastin time (APTT), prothrombin time (PT) and kidney and renal pathological changes were also observed.</p><p><b>RESULT</b>Compared to injured skin rats, mercury contents of blood, urine and kidney were increased significantly in low, middle and high-dose BDSJS groups administered for consecutive 4 weeks. The levels of mercury showed decreases in urine (89%, 78%, 93%) and kidney (55%, 51%, 57%), and blood mercury concentration recovered to the normal range in low, middle and high-dose BDSJS groups after the drug withdrawal for 4 weeks. Kidney coefficient and beta2-MG were remarkably increased and renal tubular epithelial cell swelling could be found in the high-dose group, and kidney coefficient, beta2-MG and renal morphology basically recovered to the normal levels after the drug withdrawal for 4 weeks.</p><p><b>CONCLUSION</b>The administration of BDSJS for consecutively 4 weeks can cause mercury accumulation in blood and mainly in kidney. Once the accumulated mercury concentration of kidney reaches a certain level, renal tubular epithelial cells would be injured. 1.1 mg x cm(-2) of BDSJS is proved to be safe and 2.2 mg x cm(-2) can cause mild but reversible injury in the function of kidney which can be recovered after drug withdrawal for 4 weeks.</p>

ABSTRACT

Badu Shengji San(BDSJS) is a traditional Chinese medicine (TCM) used for drawing out toxin, eliminating suppuration and promoting granulation. Toxic minerals such as arsenic and lead are the two most important components of BDSJS. Previous hypothesis indicated that according to the compatibility theory of TCM, the toxicity of the entire BDSJS was weaker than that of arsenic and lead, respectively. In the present study, SD rats with injured skin were treated with distilled water and different composition of BDSJS (complete formulations, compatible herbs, mineral medicine containing arsenic and lead, mineral medicine containing arsenic and mineral medicine containing lead) once a day for consecutive 2 weeks. Kidney coefficient and urinary beta-N-acetyl glucosidase (NAG) were used as the indicators of renal toxicity and the content of malondiadehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), glutathione (GSH) and metallothionein (MT) in the renal tissue were measured. Our data showed that kidney coefficient, the severity of renal pathological lesion and MT level in the kidney of the entire BDSJS group decreased significantly compared with arsenic and lead group. Additionally, the NAG content of the entire BDSJS group had the decreased trend. The kidney CuZn-SOD level of the entire BDSJS group had the increased trend, but the MDA, GSH-PX, GSH level had no obvious difference. Our results suggested that compatible herbs in BDSJS relieved renal injury induced by arsenic and lead, and the attenuation mechanism may be related to MT and CuZn-SOD, but not to MDA, GSH-PX and GSH directly.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the anticancer and anti-metastatic effect of Ajuga decumbens extraction (HBG) on breast cancer and to clarify the effect of HBG on MMPs and TIMPs.</p><p><b>METHOD</b>The antitumor and antimetastic effect of HBG was determined using orthotopic 4T1 breast cancer mouse model. Western blot analysis was employed to detect the expression of associated proteins in breast cancer metastasis.</p><p><b>RESULT</b>Administration with 50-200 mg x kg(-1) doses of HBG significantly reduced the tumor weight, tumor volume and numbers of lung tumor nodules in a dose-dependent manner. Tumor metastasis correlated proteins were altered following HBG treatment, MMP-2 and MMP-9 were down-regulated while TIMP-1 and TIMP-2 were up-regulated.</p><p><b>CONCLUSION</b>HBG showed anticancer and antimetastatic effect towards breast cancer through regulating the expression of MMPs and TIMPs. These data sustain our contention that HBG might be used as a potential therapeutic agent.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the effect of Magnolia officinalis and M. officinalis var. biloba on gastrointestinal motility dysfunction.</p><p><b>METHOD</b>The gastrointestinal motility dysfunction induced by atropine and L-Arg were used in this study. The effect of M. officinalis on the gastrointestinal function was evaluated by propulsive motility of the total gastrointestinal tract test by recording the time of excreting carbo medicinalis, the gastric residualrate, the intestinal propulsion rate, the serum levels of D-xylose, motilin (MTL) and gastrin (GAS). ED50 were calculated with Bliss's method.</p><p><b>RESULT</b>M. officinalis and M. officinalis var. biloba improved the gastrointestinal motility, decreased the gastric residual rate, enhanced the intestinal propulsion rate and increased serum levels of D-xylose, motilin (MTL) and gastrin(GAS). The ED50 value of M. officinalis var. biloba was much higher than that of M. officinalis.</p><p><b>CONCLUSION</b>The effect of improving gastrointestinal motility of M. officinalis was proved to be superior to that of M. officinalis var. biloba.</p>

ABSTRACT

BACKGROUND: Application of traditional osteoarthritis animal models was limited by long duplicated time, poor stability, different successful rate, and rough analysis of osteoarthritis.OBJECTIVE: To observe clinical and pathological features of osteoarthritis by modified Hulth modeling way and to determine the stages of ostecarthritis.METHODS: A 2-cm medial longitudinal incision was resected to expose knee joint. Anterior and posterior cruciate ligament and medial collateral ligament were cut off, and medial meniscus was fully cut to reserve articular cartilage., The injured limb was not fixed postoperatively. Animals were allowed to move freely. At one week after surgery, 800 000 U penicillin was used to avoid from infection, 30 mind, twice per day, for 12 successive weeks. The normal group was treated without any treatments. Pathological features were observed using Mankin scores under electron and optic microscope at 4, 6, 8, 10, and 12 weeks postoperatively.RESULTS AND CONCLUSION: Changes of osteoarthritis were observed in the model group at 4 and 6 weeks after operation,showing synovial hyperemia and hyperplasia, increased synovial fluid effusion, cartilage surface roughness, matrix stained tinge,and Mankin score of 3.5-3.8. Intermediate stage changes of osteoarthdUs were found in the model group at 8 weeks after operation, showing synovial hyperplasia, less synovial fluid, flssuration reaching cartilage surface, cartilage cells with tangled and uneven staining matrix, Mankins score of 8-9. Advanced osteoarthritis changes were observed in the model group at 12 weeks after operation, showing severe nodular synovial hyperplasia, less and turbid synovial fluid, osteophyte formation of serious exposure of subchondral bone, cartilage calls reducing the majority of loss of matrix staining, and Mankin score of 12-14. Electron microscopy indicated a coincidence with the histological observation of cell mutation. The rabbit model by Hulth suggested that early change of osteoarthritis occurred at 6 weeks after operation, intermediate stage at 8 weeks, and advanced stage at 12 weeks.This model could be more comprehensive response to osteoarthdtis cartilage degeneration from early compensatory hypertrophy to decompensation after the cartilage cells and matrix reduction, cartilage softened to endarterectomy missing characterized the late changes in the entire process.
