Chinese Journal of Dermatology 2016;49(11):815-817
Objective To detect serum levels of 25 ? hydroxyvitamin D (25 [OH] D) and matrix metalloproteinase 9(MMP?9)in patients with chronic spontaneous urticaria(CSU), and to explore their significance. Methods Totally, 56 patients with CSU and 25 healthy controls were enrolled into this study. High?performance liquid chromatography tandem?mass spectrometry(LC?MS/MS)and enzyme?linked immunosorbent assay(ELISA) were performed to measure serum levels of 25(OH)D and MMP?9 respectively in these subjects. Statistical analysis was carried out by two independent samples t?test or Wilcoxon rank sum test for comparisons of the above indexes between the two groups, and by Spearman rank correlation analysis for assessment of relationships between the serum levels of 25(OH)D and MMP?9 as well as between the two indexes and disease severity. Results Of the 56 patients, 19 were diagnosed with mild CSU, 26 with moderate CSU and 11 with severe CSU. Compared with the control group, the patient group showed significantly lower serum levels of 25(OH)D(21.74 ± 6.04 vs. 30.17 ± 2.21μg/L, P<0.05), but significantly higher serum levels of MMP?9(Median[P25-P75]:291.55[166.18-594.46]vs. 138.46[94.27-233.12]μg/L, P<0.05). In the patient group, the serum level of 25(OH)D was negatively correlated with that of MMP?9 (rs=-0.26, P<0.05), but uncorrelated with the severity of CSU(rs=-0.20, P>0.05);the serum level of MMP?9 was positively correlated with the severity of CSU(rs=0.27, P<0.05). Conclusion Vitamin D and MMP?9 may play a role in the occurrence of CSU.

Objective To explore the possible causes that result in serum-resistance of patients with syphilis. Methods Cerebrospinal fluid(CSF) routine and biochemistry, RPR, TPPA, and immunological function in 25 patients with syphilis serum-resistance were detected after giving the standard therapy, and radiographic examination of multiple internal organs was performed as well. All patients were treated with 24 million units of Penicillin G per day by intravenous drip for 14 days followed by muscle injection of Bicillin 2.4 million units weekly for 3 weeks after leaving hospital. Blood serum RPR was reexamined 3 and 6 months after treatment, respectively. Results Among 25 patients CSF-TPPA was positive in 11 cases, all patients' CSF-RPR were negative, CSF-WBC and CSF-Pr increased in 7 patients, serum IgM level increased and C3 decreased in 10 cases (40%), and CD_3+CD_8+ cell count increased and NK cell count decreased in 21 cases (84%). The regurgitation of bicuspid valve, tricuspid valve and aortic value was found in 3 patients. The RPR titers in all patients did not decrease after treatment according to neurosyphlis. Conclusion Asymptomatic neurosyphilis and immune disorder may be causes of serum-resistance of syphilis.

Objective·To observe changes of exhaled nitric oxide (FeNO) level in patients with chronic obstructive pulmonary disease (COPD) before and after inhaled corticosteroid (ICS) therapy and to explore the correlation of FeNO level with inflammation and pulmonary function indexes. Methods·Seventy COPD patients at stable stage who underwent ICS therapy (the COPD group) were enrolled. Levels of peripheral blood eosinophil (Eos) and neutrophil (N), FeNO, PEF, FEV1 and FEV1/pred before and after treatment were measured. Fifty healthy volunteers who received physical examination at the same time served as controls (the control group). The relationship between these indexes and clinical efficacy and the correlation between FeNO level and inflammation or pulmonary function indexes were analyzed. Results·The COPD group had significantly higher FeNO, Eos, and N levels before treatment, significantly lower PEF, FEV1 and FEV1/pred after treatment (P<0.05), and remarkably better indexes after treatment (P<0.05) compared with the control group. Indexes of the effective group and the improved group were significantly better than that of the ineffective group after treatment. Results of correlation analysis showed that before treatment, the FeNO level was positively correlated with peripheral blood Eos and N levels (P<0.05) and negatively correlated with PEF, FEV1 and FEV1/pred (P<0.05). After treatment, the FeNO level was positively correlated with peripheral blood Eos and N levels (P<0.05) and the correlation of the FeNO level with PEF, FEV1 and FEV1/pred was not statistically significant (P>0.05). Conclusion·The FeNO level increased significantly in patients with COPD at stable stage and is a sensitive index of airway inflammation. Combined with lung function test, it's useful for evaluating the efficacy of ICS and guiding treatment.
