Background The main cause of filtering surgery failure is over proliferation of fibroblasts in filtering channels,leading to excessive fibrosis and scar formation.Researches determined that p38 mitogen-activated protein kinase(MAPK) signaling pathway plays an important role in fibroblast phenotype transition. Objective The present study was to investigate the inhibitory effect of p38 MAPK inhibitor on myofibroblasts transdifferentiation and the extracellular matrix synthesis after filtration surgery in rabbit eyes. Methods Trabeculectomy was performed on 24 eyes of 12 clean New Zealand white rabbits to establish the filtering operative models.The models were randomized into model group,SB203580 group and mitomycin C ( MMC ) group.1 ml SB203580 ( 0.2 g/L) was conjunctively injected at the end of operation in the rabbits of the SB203580 group,and the cotton piece with 0.2 g/L MMC solution was placed on the operative area for 3 minutes intraoperatively in the rabbits of the MMC group.The bleb appearances were examined under the slit lamp microscope,and intraocular pressure(IOP) was measured with Icare tonometer I,3,7,10,14 days after operation.0.2 ml aqueous humor was extracted and the conjunctive tissue at the filtering area was obtained 14 days after operation for the detection of α-smooth muscle actin (α-SMA) and fibronectin protein by ELISA.Expression of ACTA2 mRNA,connective tissue growth factor(CTGF) mRNA and alpha2 chain of type Ⅰ collagen( COL1A2 )mRNA in conjunctive tissue was assayed with fluorescence real-time PCR. Results Vascularization of fibrosis of filtering bleb were obvious in the eyes of the model group,and the bleb was flat and diffuse in the eyes of the SB203580 group and MMC group on 14 days following operation.No significant difference was seen in IOP before trabeculectomy among these three groups( F=0.065,P=0.937 ).IOP was gradually elevated with the increase of time after operation ( F =32.873,P =0.030 ).ELISA assay showed that α-SMA level in conjunctiva was lower in the SB203580 group and MMC group compared with the model group,and that of MMC group was significant lower than the SB203580 group( P<0.05 ).Fibronectin level in conjunctiva was lower in the SB203580 group and MMC group compared with the model group,and that of MMC group was significant lower than the SB203580 group (P<0.05).Fluorescence real-time PCR showed that expressions of the ACTA2 mRNA,CTGF mRNA and COL1A2 mRNA were significantly different among the three groups( P<0.01 ),with the highest expression in model group and the lowest expression in the MMC group ( P < 0.05 ). Conclusions Fibrotic reaction after trabeculectomy can be suppressed by inhibiting p38 MAPK signal pathway.The mechanism of SB203580 is to reduce the synthesis of myofibroblasts transdiffercntiation and extracellular matrix.

Objective To explore the clinical and pandemic features and respiratory pathogen co-infection characteristics of children infected with influenza virus A (Flu A) in year 2009.Methods A retrospective study of hospitalized children with flu-like clinical symptoms in 2009 was conducted.The peripheral blood serum was analyzed to detect common respiratory agents,inclucding Flu A,respiratory syncytial virus,adenovirus,influenza virus B,parainfluenza virus 1,2 and 3,chlamydia pneumonia and mycoplasma pneumonia,klebsiella pneumonia (KP),haemophilus influenza and legionella pneumophila by using indirect immunofluorescence test for the antibody detection (IgM).And a standard medical history was recorded,including epidemiological data,clinical manifestation,and the length of hospital stay,white blood count and chest X-ray elsewhere.All specimens were collected in Department of Pediatrics,Zhongnan Hospital of Wuhan University,from Jan.2009 to Dec.2009.Results Flu A was detected in 234 of the 599 (39.1%,234/599 cases) flu-like children.The mean age was 48.8 months (range from 3 to 167 months).The detection rate in less than 1-year-old group (11.1%,18/162 cases) was obviously lower than that of the older groups (P < O.001).Especially for the group < 6 months,there was only 1 infant (1.43%,1/70 cases) with Flu A positive.Compared with Flu A negative group,the main clinical features of children with Flu A positive group were fever(78.2%,183/234 cases,P =0.013) and cough(76.5%,179/234 cases,P =0.04),however asthma (14.1%,33/234 cases,P =0.003)and diarrhea (6.0%,14/234 cases,P = 0.001) cases were less.The detection rates of Flu A reached a peak of 57.0% in November and December,and a secondary peak of 45.0% in May and June.Flu A infection children less than 1 year old were simple in etiology.The children were older,the etiology was more complex.The primary coinfection pathogen was KP (53.8%,126/234 cases) and Flu B(48.3%,113/234 cases).Compared Flu A coinfection with or without KP,there was no difference between these 2 groups in the clinical features.Conclusions Intfluenza A is the main pathogen of hospitalized children with flu-like symptoms in 2009.Children over 1 year old age were the major infection groups of Flu A.The detection rates of Flu A reached peaks in May to June and November to December.Flu A positive children were prone to KP coinfection.

Objective To assess the value of hemofiltration in the prevention of contrast induced nephropathy(CIN) post percutaneous coronary intervention(PCI) in severe chronic kidney disease stages(CKD) patients. Methods We evaluated 30 CKD patients who underwent PCI followed by bedside hemofiltration. We measured serum creatinine levels before PCI, 24 hours, 72 hours, and one week after PCI, and calculated creatinine clearance(CrCl) according to Cockcroft and Gault equation.We observed the incidence of CIN, and the short term clinical efficacy of hemofiltralion. Results The average age of the 30 patients was (72.87 ± 8.71) years old, with 21 (70%) male patients. The stages of CKD among the patients included CKD 3 (3 patients, 10%), CKD 4 (20 patients, 66.7%) and CKD 5 (7 patients, 23.3%). The average duration of hemofiltration was (7.5±4.1) hours. Serum creatinine before PCI, 24 hours, 72 hours and 1 week after PCI was (498.7±143.7)μmol/L, (353.2±128.0)μmol/L, (450.0±132.2)μmol/L, (488.0±145.7)μmol/L respectively,and CrCl was (20.3±10.2) ml/min, (36.5±14.3) ml/min, (28.3±10.4) ml/min, (21.0±10.3) ml/min respectively. There was no CIN. Mean follow-up was (3.1 ± 2.6) months. There was no new cardiovascular events, and no new patients need to rely on long term hemodialysis. Conclusions For patients with severe renal insufficiency, hemofiltration may reduce the incidence of CIN, It is an alternative preventive measures to prevent CIN.

Objective To evaluate the diagnostic value of non-invasive imaging modalities to evaluate lower limb arterial disease associated with diabetes.Methods Two hundred and twenty seven patients (292 lower limb arteries) with lower limb arterial disease due to diabetes underwent both DSA and one of the pre-operative imaging modalities including CTA,CE-MRA and DUS were included in this study.The diagnostic consistency of CT angiography(CTA),contrast enhanced magnetic resonance angiography (CE-MRA) and Doppler ultrasonography(DUS) compared with DSA were calculated respectively.CTA was performed in 169 lower limb arteries,while 123 in CE-MRA and DUS in 192.DSA was used as the gold standard.Consistency analysis was performed to evaluate the three imaging modalities with lower limb artery classified as Grade 1,Grade 2 and Grade 3.Results The sensitivity of CTA to evaluate mild stenosis in Grade 1 to Grade 3 was 100%(56/56),97.6%(82/84) and 93.8%(30/32) respectively,while 100%(19/19),94.4% (34/36)and 61.5% (8/13) for severe stenosis.The diagnostic accuracy of mild and severe stenosis was 95.9% (162/169) to 99.4% (168/169),which showed good consistency with the result of DSA with Kappa value of 0.760 to 0.916,and P<0.05.The sensitivity of CE-MRA to evaluate mild stenosis in Grade 1 to Grade 3 was 93.2%(68/73),97.2%(103/106) and 93.2% (69/74)respectively,while 91.3% (21/23),80.8% (42/52)and 42.1% (8/19)for severe stenosis.The diagnostic accuracy of mild and severe stenosis was 86.2% (106/123) to 96.7% (119/123),which showed good consistency with the result of DSA with Kappa value of 0.767 to 0.868 and P<0.05.The sensitivity of DUS to evaluate mild stenosis in Grade 1 to Grade 3 was 89.9% (62/69),88.8% (87/98) and 79.2% (42/53) respectively,while 73.1% (19/26),84.8% (39/46) and 44.4% (8/18) for severe stenosis.The diagnostic accuracy of mild and severe stenosis was 89.7% (174/194) to 93.8% (182/194),which showed good consistency with the result of DSA with Kappa value of 0.476 to 0.864 and P<0.05.Conclusions The non-invasive imaging modalities,namely CTA,CE-MRA and DUS all have good diagnostic consistency compared with DSA.CTA is superior to CE-MRA and DUS in evaluating the severe stenosis of lower limb arterial disease in diabetes patients.
