Objective To observe the changes of serum sphingosine-1-phosphate (S1P) level in asthmatic patients with different severity of bronchial asthma, and to explore the evaluation value of S1P on the severity of asthma.Methods A prospective observational study was conducted. Fifty-two patients with asthma admitted to Department of Respiratory Medicine of the First Affiliated Hospital of Jiamusi University from November 2015 to January 2017 were enrolled. According to the severity of the disease, the patients were divided into mild, moderate and severe groups. In the same period, 25 healthy subjects were served as healthy control group. All the subjects got the peripheral venous blood collection in the morning fasting, the level of serum S1P was determined by enzyme linked immunosorbent assay (ELISA), the peripheral blood eosinophil (EOS) was counted, and the pulmonary function test was performed. The correlation among the parameters was analyzed by Pearson correlation analysis. Receiver operating characteristic curve (ROC) was plotted, and the value of serum S1P on evaluating the severity of asthma was analyzed.Results Fifty-two asthma patients were enrolled, including 17 patients of the mild, 19 of the moderate, and 16 of the severe. Compared with the healthy control group, serum S1P level and peripheral blood EOS in different degree asthma groups were significantly increased, and forced expiratory volume in 1 second (FEV1) was decreased significantly; and with asthma exacerbations, serum S1P levels and peripheral blood EOS were gradually increased [mild, moderate and severe S1P (nmol/L) were 1537.0±120.3, 1980.7±149.5, 2202.2±117.2 (F= 274.624, P= 0.001); EOS (×109/L) were 0.13±0.06, 0.20±0.07, 0.37±0.14 , respectively (F= 44.093,P = 0.001)], and FEV1 was decreased gradually [mild, moderate and severe were 0.89±0.05, 0.63±0.06, 0.42±0.10, respectively (F= 159.756,P = 0.001)]. Correlation analysis showed that there were significant positive correlations between serum S1P level and peripheral blood EOS in patients with mild, moderate and severe asthma (r value was 0.696, 0.746,0.508, allP < 0.05), and negatively correlations with FEV1 were found (r value was -0.761, -0.655, -0.815, all P < 0.01). There was no significant correlation between serum S1P level and EOS, FEV1 in healthy control group (r value was 0.324 and -0.048, bothP> 0.05). ROC curve analysis showed that the area under curve (AUC) of serum S1P for assessing mild, moderate and severe asthma was 0.948, 1.000, 1.000, respectively; when the cut-off of S1P was 1181.8, 1534.2, 1708.6 nmol/L, the sensitivity was 88.2%, 100%, 100%, and the specificity was 88.0%, 100% and 100%, respectively.Conclusions During asthma attack, the serum S1P level was gradually increased with the exacerbation of the disease. Serum S1P level has significant evaluative effect on the severity of asthma.

This study was aimed to observe bronchial asthma patients in remission after treatment of traditional Chi-nese medicine(TCM) with four diagnostic information, syndrome differentiation and changes oflung function indicators, in order to explore the efficacy evaluation with TCM characteristics. TCM tongue manifestation instrument, TCM in-quiry scale, pulse-taking instrument, acoustic diagnostic information collection system, and spirometer were used in thecollection of 33 bronchial asthma cases in remission before and after treatment (1~5 months) basedon four diagnos-tic information and lung function indexes. Single-factor analysis of variance and other methods were used in the analysis of four diagnostic parameters and lung function indexes before and after treatment. The results showed that after TCM treatment, there were significant changes on indexes such as facial complexion, tongue sub-region color, color of tongue coating and other parameters. There was significant difference in the acoustic parameters before and after treatment. After TCM treatment, the frequency of lung system symptom such as nasal obstruction was decreased. There was no significant difference on changes of pulse-taking indexes among asthma patients before and after treat-ment. After treatment, the FEV1.0% of asthma patients was increased,whichindicated that asthma ventilatory function had been improved to some extent. It was concluded that TCM objective test provide an effective basis for the diag-nosis of bronchial asthma on aspects such as TCM syndrome, disease change observation and clinical evaluation.

To investigate the protein and mRNA expression of pancreas/duodenal homeobox-1 (PDX-1), a transcription factor as a marker for pancreatic stem cells, in pancreatic ductal cells of rats after partial (90%) pancreatectomy and evaluated the significance of the PDX-1 expression. Western blot and Reverse transcriptase-polymerase chain reaction (RT-PCR) were used to detect the expression of PDX-1 protein and mRNA respectively. PDX-1 protein was only faintly detected in pancreatic ductal cells on the day 1 after partial pancreatectomy. On the day 2 and 3 after operation in operation group, a 2-3 fold increased PDX-1 protein was observed, corresponding to the characteristic 42-kD protein in Western blot. There was significant difference between operation group and sham-operation group (P<0.05). PDX-1 protein expression on the day 5 and 7 after operation had already been no difference from control group (P>0.05). RT-PCR revealed the PDX-1 mRNA expression showed no significant difference between operation group at various time points and sham-operation group (P> 0.05). These results indicate that there was overexpression of PDX-1 in the cells of pancreatic epithelium during the regeneration of remnant pancreas after partial pancreatectomy in adult rats, suggesting the pancreatic stem cells in pancreatic ductal epithelial cells are involved in the regeneration of remnant pancreas and the expression of PDX-1 in ductal cells was regulated posttranscription.
