RESUMO
ObjectiveTo observe the clinical efficacy of modified Shenqi Pill （肾气丸） plus Tongdu Tiaoshen Acupuncture （通督调神针刺） in the treatment of neurogenic bladder after spinal cord injury of kidney-yang deficiency syndrome. MethodsForty-six patients were randomly divided into 23 cases each in the control group and the treatment group. Both groups were given conventional treatment， i.e. oral methylcobalamin tablets （0.5 mg each time， 3 times a day） and paraplegic conventional acupuncture （once a day， 6 consecutive days a week）. The control group was given simple bladder function rehabilitation training on the basis of the conventional treatment； and the treatment group was given modified Shenqi Pill orally （1 dose a day， 150 ml each time， taken warmly in morning and evening） and Tongdu Tiaoshen Acupuncture （once a day， 6 consecutive days per week） in addition to what were given to the control group. The treatment course lasted for 4 weeks. The 24 h urination frequency， 24 h urine leakage frequency， 24 h single urine volume， bladder residual urine volume， international lower urinary tract symptom （LUTS） score， traditional Chinese medicine （TCM） syndrome score were compared between the two groups， and clinical effectiveness and TCM syndrome effectiveness were compared between the two groups after treatment. ResultsTwenty patients in each group were finally analyzed in this study. The number of 24 h urination， the number of 24 h urine leakage， bladder residual urine volume， LUTS score， and the TCM syndrome scores decreased after treatment in both groups， and the 24 h single urine volume increased （P＜0.01）； and much more improvement was found of each index in the treatment group than in the control group （P＜0.05 or P＜0.01）. The total clinical effectiveness and TCM syndrome effectiveness in the treatment group was 85.00% （17/20） respectively， which were statistically significantly higher than 45.00% （the total clinical effectiveness， 9/20） and 60.00% （TCM syndrome effectiveness， 12/20） in the control group （P＜0.01）. ConclusionModified Shenqi Pill plus Tongdu Tiaoshen Acupuncture can signi-ficantly improve the clinical symptoms of neurogenic bladder patients after spinal cord injury of kidney-yang deficiency syndrome， having better effectiveness than simple bladder function rehabilitation training， and its mechanism may be related to the improvement of the injured nerve function innervating the bladder.
RESUMO
The association rules in data of traditional Chinese medicine prescriptions were analyzed using SQL Server 2008,which showed that 17 core compatible drug pairs were in line with the association rules.For example,platycodon grandiflorum combined with liquorice,known as Liquorice and Platycodon Decoction,can treat the principal and secondary aspects of a disease by ventilating the lungs and resolving the phlegm,removing the toxic substances and relieving the sore throat.Mining compatible drug pairs by analyzing their association rules can provide evidence for their clinical application.
RESUMO
Objective To evaluate the effect of selenomethionine (Se-Met) against ultraviolet B (UVB)-induced oxidative damage to human HaCaT keratinocytes,and to explore its possible mechanisms.Methods Cultured HaCaT cells were divided into several groups:normal control group receiving no treatment,Se-Met groups treated with Se-Met at concentrations of 1,10,50,100,200 nmol/L and 1 μmol/L for 24 hours respectively,UVB groups irradiated with UVB of 30,60 and 90 mJ/cm2 respectively,Se-Met + UVB groups treated with Se-Met at concentrations of 1,10,50,100,200 nmol/L and 1 μmol/L for 24 hours firstly,then irradiated with UVB of 30,60 and 90 mJ/cm2 respectively.Subsequently,methyl thiazolyl tetrazolium (MTT) assay was performed to estimate cellular proliferative activity,flow cytometry to detect cell apoptosis,colorimetry to evaluate superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and to determine malondialdehyde (MDA) levels.Statistical analysis was carried out by using factorial design analysis of variance (ANOVA),one-way ANOVA and least significant difference (LSD) test.Results Factorial design ANOVA showed that UVB radiation had an inhibitory effect on the proliferative activity of HaCaT cells (F =128.04,P ＜ 0.05),which significantly decreased along with the increase of UVB doses,with significant differences between the three UVB groups (P ＜ 0.05).Se-Met pretreatment also affected cellular proliferative activity (F =5.95,P ＜ 0.05),which was significantly increased in Se-Met (10 nmol/L-1 μmol/L) + UVB groups compared with the UVB groups at corresponding doses (all P ＜ 0.05).There was no significant interaction effect on cellular proliferative activity between UVB radiation and Se-Met pretreatment (F =1.65,P ＞ 0.05).The apoptosis rate of HaCaT cells in the 30-mJ/cm2 UVB group was 31.9％ ± 2.67％,significantly higher than that in the normal control group (4.1％ ± 0.67％,P＜ 0.05) and in the 10-,50-,100-,200-nmol/L and 1-μmol/L Se-Met + 30-mJ/cm2 UVB groups (21.9％ ± 3.72％,17.2％ ± 1.67％,4.6％ ±-0.85％,7.5％ ± 1.86％ and 13.5％ ± 1.95％ respectively,all P ＜ 0.05).Similarly,SOD and GSH-Px activities were significantly weaker (both P ＜ 0.05),while MDA levels were higher (all P ＜ 0.05) in the 30-mJ/cm2 UVB group than in the normal control group;however,there was a significant increase in SOD and GSH-Px activities but a decrease in MDA levels in the Se-Met (10 nmol/L-1 μmol/L) + 30-mJ/cm2 UVB groups compared with the 30-mJ/cm2 UVB group (all P ＜ 0.05).Conclusions Se-Met can reduce UVB-induced oxidative damage to HaCaT cells,likely by enhancing antioxidase activity and decreasing oxygen radicals.
RESUMO
AIM: To investigate the protective effect of sodium selenite ( Na2 SeO3 ) on human keratinocytes under ultraviolet-B (UVB) irradiation.METHODS: The cultured HaCaT cells were divided into 4 groups: (1) normal control group;(2) Na2 SeO3 group:pretreated with Na2 SeO3 at doses of 10 nmol/L, 50 nmol/L, 100 nmol/L, 200 nmol/L and 1 μmol/L for 24 h;(3) UVB group: irradiated with UVB at doses of 300, 600 and 900 J/m2; (4) Na2SeO3 +UVB group:after pretreated with Na2SeO3 for 24 h, irradiated with UVB at doses of 300, 600 and 900 J/m2.The cell pro-liferation was detected by MTT assay .The apoptotic rates of HaCaT cells treated with UVB at dose of 300 J/m2 were as-sessed by flow cytometry .RESULTS:Compared with normal control group , the cell proliferation activity in UVB group de-creased significantly ( P<0.05 ) .The cell activity was inversely correlated with the irradiation intensity .No significant difference of the cell activity between Na 2 SeO3 group and normal control group was observed .The cell proliferation in Na2SeO3 +UVB group was higher than that in UVB group significantly (P<0.05).Na2SeO3 at concentration of 100 nmol/L showed the strongest activity to promote cell proliferation .After 300 J/m2 UVB irradiation, the apoptotic rate in Na2SeO3+UVB group decreased significantly ( P<0.05) compared with UVB group .The inhibitory effect of Na 2 SeO3 at concentra-tion of 100 nmol/L on apoptosis was the strongest .CONCLUSION: The damage of human keratinocytes by UVB irradia-tion is in a dose-dependent manner .The photoprotection performance of Na 2 SeO3 reduces the damage of human keratino-cytes induced by UVB irradiation .
