RESUMO
Objective::To observe the clinical efficacy of Gandouling decoction on hepatic function of patients with phlegm and blood stasis type Wilson's disease. Method::From January 2015 to December 2017, totally 72 cases of phlegm and blood stasis type Wilson's disease admitted to Encephalopathy Center in the First Affiliated Hospital of Anhui University of Chinese Medicine were randomly divided into treatment group and control group, with 36 cases in each group. Patients in both groups were injected with sodium dimercaptopropane sulfonate for routine treatment. At the same time, patients in control group received Hugan Tablets, and patients in treatment group received Gandouling decoction for a total of 6 treatment courses. Before and after treatment, traditional Chinese medicine(TCM)syndrome effective rate, serum enzyme index [alanine aminotransferase(ALT), aspartate aminotransferase (AST), alkaline phosphatase(AKP)], bilirubin metabolism index [total bilirubin(TBIL)], liver fibrosis index [laminin(LN), hyaluronic acid(HA), collagen type IV(CⅣ), procollagen type Ⅲ peptide(PⅢP)]and blood coagulation index [fibrinogen (FBG), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) ]were observed. Result::TCM syndrome effective rates of treatment group and control group were 86.11%(31/36) and 63.98%(23/36) respectively, with a significant difference between two groups (P<0.05). ALT, AST, AKP, TBIL decreased in two groups after treatment (P<0.01), and the effects of ALT, AST, AKP, TBIL in treatment group were significantly better than those in control group (P<0.01), liver fibrosis index decreased in both groups after treatment (P<0.01), and the effect in treatment group was significantly better than that in control group (P<0.01). Blood coagulation indexes were improved to different degrees in both groups (P<0.05, P<0.01), and there were significant differences between treatment group and control group in decreasing PT, APTT, TT levels (P<0.05, P<0.01) and increasing FBG level (P<0.01). Conclusion::Gandouling decoction can significantly improve hepatic function of patients with phlegm and blood stasis type Wilson's disease, which is manifested in improving serum enzymes and bilirubin indexes, reversing liver fibrosis, promoting clotting factors and reducing bleeding tendency, in order to delay the progress of the disease and improve the life quality of patients.
RESUMO
OBJECTIVE:To investigate the clinical characteristics and rules of allergic reaction caused by anti-copper treat-ment with Sodium dimercaptoproane sulfonate(DMPS)injection,and to provide reference for diagnosis,treatment and monitoring of drug-induced allergic reaction. METHODS:By using retrospective analysis,allergic reaction reports of DMPS injection were se-lected from our hospital during Jan. 2013-Dec. 2015 were analyzed statistically. RESULTS:A total of 131 cases of allergic reaction were reported. The average age of the patients was(23.26±9.63)years old,mainly concentrated on 10-39 years old(87.79%). Al-lergic reaction mainly occurred in the first and second courses of treatment,accounting for 71.76%. For systems-organs involved, skin and its appendages disorders had the highest proportion (85.90%),being mainly the lesion of limbs (27.45%) and body (22.22%) involved;followed by systemic damage (12.33%). Clinical manifestations of systemic impairment were mainly fever, with rash or itching at the same time frequently. 131 patients had good outcome after treatment. The symptoms of 115 patients (87.79%)disappeared in 7 d. Serious cases accounted for 25.19%. The proportion of drug allergy history,the rate of anti-copper treatment failure with allergy prevention or desensitization therapy,and symptom duration in patients with severe ADR were higher or longer than that in general ADR cases,the difference was statistically significant(P<0.05). CONCLUSIONS:The allergic reac-tion of DMPS injection increased the difficulty of anti-copper treatment. ADR monitoring should be strengthened in the process of using DMPS,specially for the history of allergies and the first,second treatment courses of patients.
RESUMO
OBJECTIVE: To evaluate the efficacy and safety of sodium dimercaptopropane sulfonate( DMPS) in the treatment of patients with increased urinary mercury. METHODS: By random sampling method,68 patients with elevated urinary mercury were chosen as study subjects. Among them,61 cases were observation subjects working with mercury and 7 cases were chronic occupational mild mercury poisoning. DMPS was used to eliminate mercury by intramuscular injection. The changes of urinary mercury level were observed before and after treatment,and the curative effect was analyzed. RESULTS: The median( the 25 th and 75 th percentiles) of natural voiding urinary mercury was 36. 6( 28. 4,55. 6) μmol / mol creatinine and 24 hours total urine mercury amount was 1 074. 7( 608. 0,1 646. 3) μg / d in the first course of treatment.After 1 to 8 courses of mercury expulsion,the 24 hours total urine mercury amount in 68 patients were lower than the normal reference level( 45. 0 μg / d). The median( the 25 th and 75 th percentiles) of one-time morning urinary mercury level before hospital discharge was 2. 7( 1. 8,4. 0) μmol / mol creatinin,which was lower than the level of natural voiding urinary mercury( P < 0. 05). The first and second course of treatment resulted in the highest decline in urinary mercury,followed by a gradually decreased in urinary mercury in later courses. The number of treatment courses in observation subjects working with mercury was less than that in patients with chronic mild mercury poisoning [( 4. 0 ± 1. 3) vs( 5. 6 ±1. 1) times,P < 0. 05]. There was a positive correlation between the number of treatment courses and the level of natural voiding urinary mercury or 24 hours total urine mercury amount in the first course of treatment( P < 0. 01). The number of courses of mercury expulsion was not related to gender,length of service and age( P > 0. 05). One patient had dizziness and pale after intramuscular injection of DMPS,the symptom was disappeared with symptomatic treatment; 68 patients after treatment have no other adverse reactions. CONCLUSION: Using DMPS as mercury displacement treatment was effective and relatively safe. The change of urinary mercury after DMPS treatment can be used as a basis for establishing clinical standard for patients with increased urinary mercury.
RESUMO
OBJECTIVE To study the changes in matrix metalloproteinase-9 (MMP-9) mRNA, tissue-inhibitor of metalloproteinase-1 (TIMP-1) mRNA and the ratio of MMP-9 mRNA/TIMP-1 mRNA in the lungs of paraquate poisoning rats, and to investigate the protective effects of sodium dimercaptopropane sulfonate (DMPS, Unithiol). METHODS One hundred and twenty male SD rats were divided into 12 groups (n=10) randomly: normal control, DMPS control, PQ poisoning 1, 3, 7, 14 and 28 d model groups, (DMPS+PQ) 1, 3, 7, 14 and 28 d groups. PQ poisoning model was established by intraperitoneal injecting paraquate. The expression of MMP-9 mRNA and TIMP-1 mRNA in lung tissues was detected by RT-PCR. RESULTS ①By observing the changes of action and observing the lung tissues sections, the rats' PQ poisoning models was successfully established. ②The histopathology of lung showed infiltration of inflammatory cell in acute phase(within 2 weeks), the inflammation decreased gradually after 2 weeks, hyperplasia of collagen and pulmonary fibrosis were instead. Howerer, the pathological changes were alleviated obviously in the (DMPS+PQ) groups. ③Compared with the PQ groups, the expression of MMP-9 mRNA and TIMP-1 mRNA in lungs diminished greatly in the DMPS+PQ groups after rats injected DMPS(P<0.05); the ratio of MMP-9/TIMP-1 mRNA was bigger at 7, 14 and 28 d in the DMPS+PQ groups after rats injected DMPS. CONCLUSION Down-regulation of the expression of MMP-9 mRNA and TIMP-1 mRNA and up-regulation ratio of MMP-9 mRNA/TIMP-1 mRNA by DMPS may be one of mechanisms by which pulmonary injury and pulmonary fibrosis are prevented in the acute paraquate poisoning.
RESUMO
To investigate the therapeutic effect of high-dosage γ-aminobutyric acid (GABA) on acute tetramine (TET) poisoning, 50 Kunming mice were divided into 5 groups at random and the antidotal effects of GABA or sodium dimercaptopropane sulfonate (Na-DMPS) on poisoned mice in different groups were observed in order to compare the therapeutic effects of high-dosage GABA with those of Na-DMPS. Slices of brain tissue of the poisoned mice were made to examine pathological changes of cells. The survival analysis was employed. Our results showed that both high-dosage GABA and Na-DMPS could obviously prolong the survival time, delay onset of convulsion and muscular twitch, and ameliorate the symptoms after acute tetramine poisoning in the mice.Better effects could be achieved with earlier use of high dosage GABA or Na-DMPS. There was no significant difference in prolonging the survival time between high-dose GABA and Na-DMPS used immediately after poisioning. It is concluded that high-dosage GABA can effectively antagonize acute toxicity of teramine in mice. And it is suggested that high-dosage GABA may be used as an excellent antidote for acute TET poisoning in clinical practice. The indications and correct dosage for clinical use awaits to be further studied.
