AlM: To analyze the effect of corneal limbus stem cell transplantation and amniotic membrane transplantation in treatment of recurrent pterygium with symblepharon.
METHODS:Totally 80 cases of patients with recurrent pterygium and symblepharon were randomly divided into pterygium resection combined with limbal stem cell transplantation group and pterygium excision with amniotic membrane transplantation group, 40 cases in each group. All patients were followed up for 6mo after the operation, the recurrence rate of pterygium and symblepharon were observed.
RESULTS:There were 2 cases of recurrence in the group of corneal limbus stem cell transplantation (5%), 8 cases of recurrence in the group of amniotic membrane transplantation (20%), with statistical difference between two groups (P<0. 05).
CONCLUSlON:Two kinds operation could significantly reduce the recurrence rate of recurrent pterygium, but the corneal limbus stem cell transplantation group has the lower recurrence rate.

Objective To analyse the problems presented in external quality assessment (EQA)for blood cytomorphology and propose measures for improvement.Methods Statistical analysis was performed on EQA results for blood cytomorphology from 2011 to 2013 in Shaanxi Province,including general information of participant laboratories,coincident rate,and reported incorrect results.EQA for blood cytomorphology was held two times every year in Shaanxi province,with ten pictures inclu-ding bone marrow and peripheral blood smear each time.The compact disc including twenty pictures was given to partici-pants by EMS.Participants reported two EQA results in April and September each year.The center statisticed the EQA re-sults and provided the EQA reports to every participants in June and November.Results Participating laboratories increased from 76 in 2011 to 163 in 2013.The ratio of laboratories with the coincidence rate≥80% was 80%,47%,44%,55%,77%and 96% respectively.The number for single cell with the coincidence rate≥80% was 38.The coincidence rate of peripheral blood cells was higher than that of the bone marrow on the whole.Causes of incorrect results included cell lines’misclassifi-cation,growth stage’s misclassification,insufficient identification of abnormal cytomorphology,and so on.Conclusion The identification of blood cytomorphology was unbalanced in different leveled hospitals in Shaanxi Province.To develop EQA of blood cytomorphology definitely has a positive role in improving the experimenters’skill of identifying cytomorphology.

Objective The goal of this study was to investigate the correlation between the level of serum vitamin D and bone metabolism and disease activity in ankylosing spondylitis(AS) patients,and thus to explore the role of vitamin D in bone metabolism in AS patients.Methods The serum levels of BALP,TRACP-5b,25-(OH)D3 and blood lymphocytes VDR of 80 AS patients were measured by enzyme-linked immunosorbent assay (ELISA) and compared with those of the control group.Bone mineral density (BMD)was measured by dual-energy X-ray absorptiometry (DEXA).The ESR and CRP level of AS patients were also measured.The correlation between those parameters was analyzed and evaluated.Patients were divided into normal,insufficient and deficient subgroups according to the serum 25-(OH)D3 levels for further comparison.Indepondent saimple t test,t'test andx2 test were used for statistical analysis.Results The 25-(OH)D3 of AS patients [(11.9±2.7) μg/L] was significantly lower than that of the control groups [(22.3±7.9) μg/L] (P＜0.05),while the serum levels of BALP [(3.9±2.7) μg/L] and TRACP-5b [(46±25) ng/L] of AS patients were significantly higher than those of the control group [(2.4±1.0) μg/L] (P＜0.05).According to linear correlation analysis,25-(OH)D3 was negatively correlated with CRP (r=0.324,P=0.003).The ESR,BALP,TRACP-5b in the deficient subgroup were higher than those in the normal and insufficient subgroups(P＜0.05).Conclusion The plasma 25-(OH)D3 may decrease in AS patients,and this may activate bone metabolism,results in increased morbidity of osteoporo-sis,and negatively affect disease activity.

AIM: To investigate the levels of IL-18, IL-16, IL-8, eotaxin and the chymase activity in the sputum of asthmatics. METHODS: IL-18, IL-16, IL-8 and eotaxin levels were detected with sandwich ELISA procedures and chymase activity was determined spectrophotometrically (410 nm) by the rate of hydrolysis of N-succinyl-L-Ala-L-Ala-L-Pro-L-Phe-p-nitroanilide (SAAPP). RESULTS: The specific chymase activities in the severe and moderate asthmatics were higher than that in controls. Native protease inhibitors ?_1-antitrypsin (?_1-AT) and soybean trypsin inhibitor (SBTI) inhibited 71.9% and 72.1% enzymatic chymase activity, respectively. The levels of IL-18, IL-16, IL-8 and eotaxin were significantly elevated in the sputum of patients with acute asthma. There were correlations between the levels of IL-8 and IL-16 (r=0.55, P

Objective To investigate the mechanism of Smad ubiquitination-related factor 2 (Smurf2)neddylation. Methods The Smurf2 protein level was tested by overexpression of Nedd8,while the method of immunoprecipitation(IP) and Western blotting were used to analyz Smurf2-Nedd8 modification.The GST-pulldown experiment was conducted to prove protein interactions.The protein was obtained by grinding mouse tissue and Western blotting was used to test the protein expression level.Results Over expression of Nedd8 could lead to the down regulation of the Smurf2′s protein level.Smurf1 and Smurf2 could interact in the GST-pulldown experiment. Smurf1 could enhance Smurf2-Nedd8 modification.The Smurf2′s protein level was up-regulated in mouse tissue of Smurf1 C426A.Conclusion There is some relationship and also difference between Smurf1 and Smurf2.Smurf1 can enhance Smurf2-Nedd8 modification.

Objective To observe the clinical efficacy of suspended moxibustion plus Chinese medication in treating icteric hepatitis. Method Ninety-two patients with icteric hepatitis were randomized into a treatment group and a control group, 46 in each group. The treatment group was intervened by suspended moxibustion plus oral administration of Chinese medication for supplementing yang, tonifying spleen, expelling dampness, and activating blood circulation;the control group was intervened only by the same Chinese medication. The symptom and sign score, and liver function items including TBil and ALT were observed, and the clinical efficacy was compared. Result The symptom and sign scores were significantly changed in both groups after intervention (P<0.05). After intervention, there was a significant difference in comparing the symptom and sign score between the two groups (P<0.05). The TBil and ALT levels were significantly changed after intervention in both groups (P<0.05). The recovery rate and total effective rate were respectively 87.0%and 95.7%in the treatment group versus 76.1%and 82.6%in the control group, and the inter-group differences were statistically significant (P<0.05). Conclusion Suspended moxibustion plus Chinese medication is an effective method in treating icteric hepatitis.
