0.05).No partial side-effect of the medicine were discorvered in the observation process.Conclusion Long-term inspiration of low-dose GCS to treating the babies and infants with asthma has reliable security.

With the existence of capsules,lens regeneration occurs in some mammals after extracapsular lens extraction.It is usually thought that lens regenerates from resident lens epithelial cells (LECs) in the capsule.However,lens regeneration dose not mean simple redupilication of development,and transparency of the lens is affected by irregular growth,migration and transdifferention of the resident LECs.Previous studies mainly focus on the dysplasia of LECs,but update theory about lens regeneration is proposed to be associated with stem cells.Some views and suggestions in lens regeneration are concerned in current researches to better illuminate the mechanism and therapy of posterior capsular opacity.

Abstract?AIM:To compare the loss of peripapillary retinal nerve fiber layer ( RNFL ) thickness measurements by spectral-domain optical coherence tomography ( SD -OCT ) in healthy individuals and glaucoma patients with or without progression.? METHODS: A total of 60 eyes, comprising 36 glaucomatous eyes with primary open angle glaucoma (POAG) and 24 healthy controls, were included in the study over a 2-year period.All eyes underwent at least 4 serial RNFL measurements performed by Cirrus OCT every half a year over a period of 2a.Visual field ( VF) testing was performed by using the Swedish interactive threshold algorithm( SITA) Standard 30-2 program of the Humphrey field analyzer within the same week as the optic disc/RNFL photography. By masked comparative analysis of VF test results and optic disc/RNFL photographs, the eyes were classified into non -progressive and progressive glaucoma cases. Longitudinal loss of RNFL thickness was compared.?RESULTS: The mean follow-up time was 2.1 ±0.3a. Seventeen from 36 subjects were identified as progressors. Mean rates of change in average RNFL thickness were significantly higher for progressors compared with nonprogressors (2.46μm/a vs.1.21μm/a;P <0.001 ). Inferior quadrant RNFL thickness were significantly correlated with MD reduction in glaucoma eyes with progression(r=0.423, P=0.03).? CONCLUSION: Longitudinal measurements of RNFL thickness using SD-OCT show a pronounced reduction in patients with progression compared with patients without progression.Inferior RNFL thickness parameters might be more important in discriminating eyes with progressive glaucomatous optic nerve damage.

To investigate the clinical risk factors of cardiac diastolic dysfunction in type 2 DM, Doppler echocardiographic examinations were performed on 63 male patients.With a routine 2 dimensional echocardiograph, mitral and pulmonary venous flow velocity were recorded. The patients were classified into DM, IGT and NGT based on well standardized criteria of WHO. All analyses were performed by the SPSS/PC or Windows Release 9.0 Statistical Package. The risk factors of impairment of diastolic function were analyzed by regression. Results showed that the levels of blood glucose and insulin were independent risk factors for diabetic cardiac diastolic dysfunction.

Objective To compare prognosis of esophageal cancer patients with simple radiation or chemoradiotherapy.Methods Retrospective analysis 266 cases of esophageal cancer patients from June 2005 to June 2007 of,including 128 with simple radiotherapy,138 with chemotherapy during the same period,157 cases of general radiotherapy,intensity-modulated radiotherapy,109 cases of Kaplan-Meier method for calculation of survival,Log-Rank method on the clinical factors of single factor analysis,Cox regression model with factor analysis.Two groups,clinical material and adverse reaction were compared with chi-square test.Results The median survival time of the radiation group was 25 months,chemoradiotherapy group of the median survival time was 28 months.Follow-up with 1,3,5 years were 231,106,82 cases.The 1,3,4 years OS rate were 86.8 ％ (200/231),12.8 ％ (14/106),9.0 ％ (7/82).Disease-free survival (DFS) rates were 39.8 ％ (92/231),7.9 ％ (8/106),15.8 ％ (13/82).No local relapse survival (LRFS) rates were 30.8 ％ (71/231),16.2 ％ (17/106),23.7 ％ (19/82).No distant metastasis (DMFS) survival rates were 47.0 ％ (109/231),11.3 ％ (12/106),13.9 ％ (11/82).Single factor analysis results show that age,disease length,X-ray parting,different radiation method were 5 years OS independent prognostic factors.Age,disease length were DFS independent prognostic factors.Lesion length,different radiation method were LRFS independent prognostic factors for survival,lesion length and X-ray parting were without distant metastases independent prognostic factors for survival.Multiple factors analysis results showed that age,disease length,pathological type were 5 years OS related factors,and age,disease length,different treatment methods were DFS related factors,only lesions length was DMFS related factors,lesion length,different chemotherapy method was DMFS related factors of survival.The rate of serious adverse reaction of the chemoradiotherapy group was higher than radiotherapy group,the difference had statistical significance.Conclusion The chemoradiotherapy increase DFS rate,and at the same time,the incidence of adverse reaction also increases,but 5 years OS rate doesn't increased obviously.

Objective To retrospectively analyze the serum enzymes in childhood amputees as a result of earthquake,and to discuss their clinical significance.Methods From 150 children amputees who were victims of Sichuan Wenchuan earthquake in 2008 and Sichuan Lushan earthquake in 2013,45 cases with complete records of serum enzymes examinations were reviewed retrospectively.They were divided into three groups:amputation group (n=6),fasciotomy decompression group (n =5),general trauma without injury to extremity group (n =34).Serum enzyme examination data were compared for statistical analysis to find the difference among groups.Ten children who were not victims of earthquake were selected from department of orthopaedics to serve as controls,and 20 adult amputees as a result of earthquake served as another control group.Results There were significant differences in injury severity scale (ISS) and the contents of all serum enzymes,including aspartate transaminase (AST),alanine aminotransferase (ALT),creatine kinase (CK),lactate dehydrogenase (LDH),and hydroxybutyrate dehydrogenase (HBDH),between the amputation group and other patients (FISS=15.474,P＜0.001 ; FAST=10.770,P＜0.001 ; FALT=12.799,P＜0.001 ; FcK=12.848,P＜0.001; FUDH=13.126,P＜0.001; FHBDH=13.186,P＜0.001),and the difference in amputation group was even more significant.AST,LDH,HBDH in childhood amputees group were significantly higher than those in adult amputation group.The contents of ALT and CK were slightly increased.Serum enzyme contents were found to be significantly helpful for prediction of disease condition and prognosis.It was also found that CK was extremely helpful in assessing the degree of illness in patients with severe trauma,especially in patients complicated by severe soft tissue injury.In all the groups,of patients,it was found that CK rose from (129 ± 62) U/L in non-earthquake induced trauma group to (44 208 ± 39 788) U/L in earthquake amputation group,and it was thus increased more than 300 times.Its highest value even reached 117 513 U/L,which was more than 840 times of the normal.If a timely amputation or muscle compartment decompression was performed,CK might decline rapidly down to the normal value.Conclusions The comprehensive and continuous assessment of serum enzymes is mandatory during the treatment of children with acute trauma.It is of important clinical significance to correctly judge the condition and to determine optional treatment measures.

Background Aberrant proliferation of residual lens epithelial cells (LECs) is one of main causes of posterior capsular opacification (PCO).Researches indicated that Wnt3a signaling pathway promote proliferation of epithelial cells,but its effect on LECs is still unclear. Objective The present study was to investigate the effects of Wnt3a on proliferation of human LECs and its mechanism and to provide a new gene target in the prevention and treatment of PCO. Methods Human LECs line (SRA01/04 cells ) was cultured and then incubated to 6-well plate at the density of 4×105/well.A human Wnt3a cDNA expressing vector targeted human LECs was constructed to increase the Wnt3a expression in SRA01/04 cells,and pcDNA3-HA expression vector was used as the control group.The expression of Wnt3a was identified by Western blot assay after transfected.The growth and proliferation of SRA01/04 cells were detected by MTT and flow cytometry (FCM).The expressions of β-catenin,cyclin D1 and c-myc in the cells were detected by Western blot assay.β-Catenin expression was localized using immunofluorescence assay,and the expression and localization of proliferating cell nuclear antigen ( PCNA ) were analyzed by immunocytochemistry for the exploration of the active mechanism of Wnt3a to proliferation of LECs.Results Human Wnt3a cDNA expression vector was designed successfully and transiently transfected to SRA01/04 cells,and Wnt3a/SRA01/04 cells and pcDNA3-HA/SRA01/04 cells were obtained.The expression of Wnt3a was verified in the Wnt3a transfected group compared with the control group.MTT indicated that the cell proliferating rate was significantly different between the Wnt3a transfected group and the control group ( Fgroup =15.235,P =0.005 ;Ftime =369.677,P =0.000),and that in various time points after transfected was significantly different (t =20.843,P=0.001 ;t =26.214,P＜0.001 ;t=25.177,P=0.001 ;t =35.516,P＜0.001 ;t =615.056,P＜0.001 ).The proportion of SRA01/04 cells in G1 phase was 51.74％ in the Wnt3a cDNA transfected group,with a significantly decrease in comparison with 79.44％ of the control group.However,the proportion of SRA01/04 cells in S phase in the Wnt3a cDNA transfected group was higher than that of the control group (36.23％ versus 12.34％ ).The positive expression rate of PCNA protein in SRA01/04 was (47.00％ ±7.58％ ) in the Wnt3a cDNA transfected group and ( 16.00％ ±3.61％ ) in the control group with a significant difference between them (t =8.256,P＜0.01 ).After 48 hours of transfection of the Wnt3a cDNA,the expression amount of β-catenin proteins was higher and the immunofluorescence was stronger in cell nucleus,and the expressions of cyclin D1 and c-myc proteins were elevated in Wnt3a/SRA01/04 cells. Conclusions The overexpression of Wnt3a activates the Wnt/β-catenin signaling pathway and downregulates the expression of a subset of target genes,including cyclin D1 and c-myc,which plays an important role in promoting the proliferation of human LECs.
