Objective To detect the pre- and post-treatment levels of serum interleukin (IL-20) in asthmatic patients during the acute exacerbation period and to investigate the role of IL-20 in the pathogenesis of bronchial asthma and relative clinical significance. Methods Forty-five cases of mild to moderate asthma outpatients in the First Affiliated Hospital of Guangxi Medical University from May 2013 to October 2013 were chosen as the asthma group and 32 healthy people who underwent routine physical examination as the control group. All the patients were treated with inhalation salmeterol and fluticasone 50/250 μg/μg (sucking twice a day) together with ventolin if necessary , and even with theophylline sustained-release tablets as the additional treatment in moderate asthma group for 1 week. The serum levels of IL-20 as well as immunoglobulin E (IgE) were detected by ELISA in the asthma group before and after treatment as well as in the control group. Other data including ECP , the number of eosinophil ceils (EOS) and the pulmonary function (FEV1%) were detected as well. The differences of IL-20 levels between the asthma group before and after treatment and the control group were analyzed and the correlation between IL-20 and Ig E, EOS, ECP and FEV1% were analyzed. Results Compared with the healthy control group [(13.58 ± 6.17)pg/L], the levels of IL-20 in the mild and moderate asthma pretreatment group were significantly increased [(23.43 ± 13.60)pg/L and (33.78 ± 22.69)pg/L]. Compared with the mild asthma group, the levels of IL-20 in the moderate asthma pretreatment group were significantly higher. After treatment , the levels of IL-20 [(15.73 ± 8.27)pg/L and (19.64 ± 11.69)pg/L] were decreased respectively in the asthmatic patients. The Pearson correlative analysis showed that there were positive correlations between the levels of 1L-20 and IgE , EOS and ECP respectively and there were negative correlations between IL-20 levels and FEV1%. Conclusion IL-20 may be involved in the pathogenesis of asthma.

Objective To compare the effectiveness,correlativity,and acceptability of the three methods:bone marrow smear,biopsy and flow cytometry in diagnosis of lymphoma patients with bone marrow involvement.Methods 68 cases of early stage lymphoma were studied by observing and comparing positive rates of the three methods:bone marrow smear,biopsy and flow cytometry.Results After confirming the bone marrow involvement,the positive rates for the 68 cases using bone marrow smear,biopsy and flow cytometry were 16.2 ％ (11/68),33.8 ％ (23/68) and 10.3 ％ (7/68) respectively.Bone marrow biopsy had the highest positive rate compared to the other methods.It was statistically significant when comparing the differences of the 3 methods (P ＜ 0.05).According to the correlativity analysis of the 3 methods,bone marrow smear and biopsy correlated with each other (P =0.002),while flow cytometery did not (P =0.270).Conclusions Morphological examination of the bone marrow smear is a fundamental method to test bone marrow involvement in lymphoma.Bone marrow biopsy creates the highest positive rate and has clear advantage compared to the other methods,however,bone marrow smear must be used at the same time as a complement.

AIM: To investigate the effect of heme oxygenase-1 (HO-1)/carbon monoxide (CO) system on pulmonary ischemia-reperfusion injury (PIRI) in rabbits. METHODS: Single lung ischemia and reperfusion animal model was used in vivo. The rabbits were randomly divided into three groups (n=10 in each), control group (C), PIR group (I-R), PIR+ hemin group (H) and PIR+zinc protoporphyrin IX (ZnPP) group (Z). Changes of several parameters which included plasma carboxyhemoglobin (COHb) at different time points, wet to dry ratio of lung tissue weight (W/D), the injured alveoli rate (IAR) and the HO-1 enzymatic activity were measured at 180 min after reperfusion in lung tissue. The tissue slides were also stained by immunohistochemistry (IHC) and in situ hybridization (ISH) for HO-1 to detect the expression of HO-1 in lung and to analyze the optical density. The lung tissue was prepared for electron microscopic observation at 180 min after reperfusion. RESULTS: The plasma content of COHb in I-R, H, and Z group increased in a time-dependent manner after I-R. But the increment of H group was higher than that of I-R group, while that of Z group was lower. The HO-1 activity in lung tissue was highest in H group, followed by IR group, Z group, and C group (P

Objective: To compare tea polysaccharides(TPS) characteristics and their role in scavenging free radicals and reducing blood glucose(BG) in diabetic mice(DM). Methods: TPS was extracted from green,Oolong and black tea which were made from the same fresh leaves from Hubei,Fujian and Yunnan. Then the recovery rate of TPS, contents of neutral sugar, uronic acid and protein were analysed, and scavenging rate of -2Oand 稯H in vitro and hypoglycemic effect were also determined. Results: 1. The yield and contents of neutral sugar, uronic acid and protein of green tea TPS were the highest, and those of black tea TPS were the lowest. Oolong tea TPS acted the best in scavenging-2O and 稯H . 2. The hypoglycemic effect of TPS from Hubei tea was the best . The effect of TPS extracted from semi-fermented Oolong tea and fermented black tea was better than that of non-fermented green tea. 3. There were obvious differences in yield, free radical scavenging rate and effect of reducing BG among TPS extracted from tea in different regions. TPS extracted from Fujian tea had the best effect in reducing BG,but that from Yunnan tea had not. Conclusion: There was remarkable effect of region and process on physico-chemical characteristics,effect of scavenging radical and reducing blood sugar TSP.
