The statistical tests showed there were no difference between the two groups on these indicators (P>0.05)3. The comparison of Damp-heat symptom scores and pro-inflammatory cytokines levels in treatment group and control group after treatmentAfter treatment for 4 weeks, Damp-heat symptom score in treatment group was 2.45±0.99, in control group was 3.85±1.30, symptom scores in the two groups were significantly decreased compared with treatment before, by statistical test, there were significant differences (P<0.01, P<0.05). After treatment Damp-heat symptom score in treatment group was lower than in control group, by statistical test, there was significant differences (P<0.01).After treatment for 4 weeks, the serum hs-CRP level in treatment group and control group was respectively 2.63±0.67ug/L,3.32±0.89ug/L. Compared with treatment before, the serum hs-CRP level in the two groups were significantly decreased, by statistical test, there were statistically significant (P<0.01, P<0.05). The serum hs-CRP level in treatment group was significantly lower than in control group, by statistical test,there was statistically significant (P<0.01).After treatment NF-κB activity in treatment group and control group was respectively 0.54±0.19,0.68±0.23, NF-κB activity in the two groups were significantly decreased compared with treatment before (P<0.01, P<0.05). NF-κB activity in treatment group was also lower than in control group, by statistical test, there was statistically significant (P<0.05).After treatment the serum IL-6 level in treatment group was 23.36±3.64pg/ml, in control group was 34.68±6.79pg/ml, the serum IL-6 level in the two groups were significantly decreased compared with treatment before, the statistical tests showed there were significant difference (all P<0.01). The serum IL-6 in treatment group was significantly lower than in control group, by statistical test, there were significant differences (P<0.01).MCP-1 levels in treatment group and control group was respectively 22.17±3.6pg/ml,25.50±5.02pg/ml, there were significantly decreased compared with treatment before in the two groups, by statistical test, there were significant differences (all P<0.01). MCP-1 levels in treatment group was lower than in control group, the statistical tests showed there was significant difference (P<0.05).At the end of the treatment, the control group and the treatment group were respectively selected 10 cases to detect PBMC IL-6 mRNA expression, the result showed that IL-6 mRNA expression level (0.74±0.19) was significantly lower in treatment group than in control group (0.96±0.23), and there were statistically significant difference (P<0.05).4. The correlation analysis between Damp-heat factors and 24h urinary protein, NF-κB activity, serum IL-6 and urine MCP-1 content By correlation analysis of 40 damp-heat syndrome cases between damp-heat symptom scores and 24h urinary protein, damp-heat symptom scores and NF-κB activity, serum IL-6 and urine MCP-1 content before treatment, the results showed that damp-heat symptom scores was significantly positively correlated with 24h urinary protein (r=0.46,p<0.01), it also positively correlated with NF-κB activity, serum IL-6 and urine MCP-1 content (r Respectively=0.52,0.53,0.42, all p<0.01).Conclusion:1.By analysing 290 PNS cases from 2004.1 to 2010.1 in our hospital, the showed showed that Damp-heat syndrome is the principal syndrome of PNS, the occurrence in this study was 40.69%. 2. From the data of PNS cases’urinary protein, serum protein, lipids, incidence of infection, etc, the results showed that Damp-heat factor is an important reason leading to PNS patients’condition worsen. Damp-heat syndrome and infection are closely interrelated.3. Though comparing the levels of hs-CRP, IL-6, NF-κB, MCP-1 between Damp-heat syndrome group and non Damp-heat syndrome group, comparing changes of Damp-heat symptom scores and pro-inflammatory cytokines expression in Damp-heat syndrome treatment group and control group before and after treatment, analyzing the correlation between Damp-heat symptom scores and pro-inflammatory cytokines,the study showed that hs-CRP、IL-6、MCP-1-. NF-κB in Damp-heat syndrome cases abnormally increase, PNS Damp-heat syndrome is closely related to pro-inflammatory cytokines.更多还原
