Background Allograft rejection is a main cause of failure of penetrating keratoplasty,especially in the patient with high risk of rejection condition.Previous study on allograft rejection mechanism focused on limbal and corneal neovascularization,but these factors did not explain all the phenomena of allograft rejection.Research found that immune cells appeared in iris and ciliary body when rejection occurred,but the relationship between these immune cells and allograft rejection is unclear Objective This study was to evaluate the relationship between diversity of vascular permeability in the iris and ciliary body and allograft rejection after penetrating keratoplasty.Methods Seventy clean eight-week-old BALB/c mice were divided into allogeneic corneal transplantation group (60 mice) and blank control group (10 mice).Allogeneic corneal transplantation was performed with the same age of C57BL/6 mice as donor and BALB/c mice as the recipients.The grafts were examined under the slit lamp microscope and scored based on the criteria of Hegde.The mice were sacrificed and iris and ciliary tissue were obtained 5,10 days and rejection after surgery.Immunohistochemistry and reverse transcription PCR (RT-PCR) was used respectively to detect the expression diversities of occludin,zonula occludens protein-1 (ZO-1),matrix metalloproteinase-9(MMP-9),major histocompatibility complex-Ⅱ (MHC-Ⅱ),and CCR5,CCR7 and their mRNA in iris and ciliary body.Image-J image analysis software was used to calculate the quantity of positive cells on iris wholemount,and absorbance of target genes (A values).The use and care of the experimental animals complied the ARVO Resolution on the Use of Animals in Research.Results The mean survival time of corneal gratts was (17±3) days after operation.The mean score was 0.6 in 5 days and 0.5 in 10 days,and 3.3 in 18 days after operation.Expression of ZO-1 reduced significantly,and that of MMP-9 increased obviously at the time of rejection.MHC Ⅱ + cells were scattered in iris and ciliary body in normal mice,and the number of the positive cells (cells/field) was increased after operation with a peak value when rejection occurred.A significant difference was seen between normal mice and rejection mice (1559.67±350.29 vs.4021.83±495.18) (P=0.000).The expressions of occludin mRNA and ZO-1 mRNA in the iris and ciliary body decreased obviously in the rejection mice.Compared with normal mice,theA value of ZO-1 and occluding were 36.74±3.13 vs.110.11±11.88 and 57.54±3.41 vs.59.90±3.50respectively,with significant differences between them (all P＜0.05).The expressions of MMP-9 mRNA,CCR5 mRNA and CCR7 mRNA in the iris and ciliary body increased gradually with the time lapse after operation and peaked when the rejection appeared.The A value of MMP-9 mRNA,CCR5 mRNA and CCR7 mRNA were significantly higher than those of normal mice (20.29±1.19 vs.2.77±0.85 for MMP-9 mRNA; 35.43±2.56 vs.9.11±0.29 for CCR5 mRNA,and 60.83±0.87 vs.0.89 ±0.95 for CCR7 mRNA) respectively (all P＜0.05).Conclusions The permeability of vascules in the iris and ciliary body increase during the allograft rejection after penetrating keratoplasty.Increased antigen presenting cells were also detected.

The skin ulceration syndrome of sea cucumber is a kind of desease induced by bacterium.In order to investigate the bacterium of infected sea cucumber and detect the N-acyl-homoserine lactones(AHLs) se-cretion of the bacterium,7 bacterial strains were isolated from the infected sea cucumber.These strains were identified by physiological-biochemical characteristics and 16S rDNA sequence.Results show that strain C6 belongs to Tenacibaculum,strain 4 belongs to Shewanella putrefaciens group,strain TB belongs to Vibrio,strain BP2,BP3,BP4 and BP6 belong to Pseudoalteromonas,respectively.AHLs were detected with strain Agrobacterium tumefaciens KYC55.Among these bacterial strains,strain C6,4,TB,BP3 and BP4 can se-cret AHLs,while strain BP2 and BP6 can’t.And the AHLs activity differs,from the highest to the lowest are 4,TB,BP4,BP3 and C6.

Objective To explore the value of color doppler ultrasonography by bed side in the early diagnosis of HIE in full term neonates.Methods The changes of cerebral parenchymal and cerebral arterial blood stream parameter on 35 cases of neonates clinically diagnosed HIE of mild and moderate degree and 40 cases of normal newborns on the 24,48 and 72 hours after birth were observed by color doppler ultrasonography by bed side.Results 1.The cerebral parenchyma was even echo in normal newborns,but it was maldistributed and reinforced in mild asphyxia neonates and it was more serious in moderate degree.The echo of cerebral parenchyma in mild degree was near normal in 48 hours after birth,while the echo of cerebral parenchyma in moderate degree was still maldistributed and reinforced in 48 and 72 hours after birth.2.There was obvious changes in the cerebral arterial blood stream parameter and hemodynamics of the asphyxia newborns compared with normals.The systolic peak velocity(Vs)and end diastolic velocity(Vd)of the cerebral arteries in mild and moderate degree were obviously lower than that of control group in 24,48 hours after birth(Pa0.05).3.Resistance index(RI)of the cerebral arteries in mild and moderate degree were higher than that of control group in 24,48 hours after birth(Pa0.05).Conclusion Color doppler ultrasonography by bed side is a convenient,noninvasive method for diagnosing HIE.

Objective To study the clinical significance of fecal smear examination on diagnosing intestinal flora imbalance in infantile diarrhea.Methods A sterile cotton swab was used to spread a layer of fresh feces quantum satis from a sterile container on a clean slide;the smear was fixed and stained with Gram′s methods after it was air-dried,then the specimen was observed with a microscopy(field lens 100 ? eye lens 10) and recorded.Results In the acute diarrhea group(40 cases),the distribution feature of 3 floras on the fecal smears:≥50% Gram-negative bacilli in 6 cases(15%),≥50% Gram-positive cocci in 30 cases(75%) and ≥68% Gram-positive bacilli in 4 cases(10%).In the delayed and chronic diarrhea group(62 cases),the distribution feature of 3 floras on the fecal smears:≥50% Gram-negative bacilli in 7 cases(11.29%),≥50% Gram-positive cocci in 44 cases(70.97%) and ≥68% Gram-positive bacilli in 6 cases(9.68%).In the normal control group(32 cases),the distribution feature of 3 floras on the fecal smears:≥50% Gram-negative bacilli in 1 case(3.13%),≥50% Gram-positive cocci in 1 case(3.13%),and ≥68% Gram-positive bacilli in 17 cases(53.13%).For the distribution of 3 floras in the 3 groups,chi-squared test was performed,and the results showed that the difference was significant in Gram-positive cocci(?~2=47.76 P0.05).Conclusions Acute,delayed or chronic diarrhea can lead to flora imbalance.In order to timely and rapidly know the flora imbalance in children with diarrhea,clinically the simple,easily operated and practical smear staining method shall be widely applied.

OBJECTIVETo study the clinicopathologic features of different variants of primary focal segmental glomerulosclerosis (FSGS).

METHODSOne hundred and two cases of FSGS were retrieved from the archival files of Peking University First Hospital during the past 6-year period. The pathologic findings were reviewed and the degrees of active and chronic changes were assessed by morphometric analysis. The histopathologic patterns were then correlated with clinical manifestations.

RESULTSAmongst the 102 cases of primary FSGS studied, 55.9% belonged to the NOS (not other specified) variant, while the perihilar, cellular, tip and collapsing variants accounted for 6.9%, 25.5%, 4.8% and 6.9% respectively. The level of proteinuria in the cellular and tip variants were much higher than that in the NOS variant; and the incidence of nephrotic syndrome in the tip and collapsing variants was higher than that in the other three variants (chi(2) = 12.23, P < 0.05). The activity score of the cellular and collapsing variants was also higher than that of the other three variants (P < 0.05). The interval between disease onset and renal biopsy diagnosis in the perihilar variant was longer than that in the other variants. The chronicity score of this variant was higher than that of the tip and NOS variants (P < 0.05). On the other hand, the total scores of active and chronic changes of the tip variant was lower than that of the cellular and collapsing variants (P < 0.05); and its chronic score was lower than that of the NOS and perihilar variants (P < 0.05).

CONCLUSIONSThe NOS variant is the commonest morphologic pattern seen in primary FSGS. The cellular and collapsing variants are the patterns associated with active lesions, while perihilar variant is the pattern associated with chronic lesions. The tip variant shows mild pathological changes compared with the other patterns.

OBJECTIVETo evaluate the value of dual source computed tomography coronary angiography (DSCT-CA) on detecting in-stent restenosis (> 50% luminal narrowing) in symptomatic patients referred for quantitative coronary angiography (QAC).

METHODSFifty five patients (43 males) with chest pain after coronary stent implantation within 6 - 12 months were evaluated by DSCT-CA and QAC. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of DSCT-CA were calculated using coronary angiography as gold standard.

RESULTSEighty nine stents were implanted. In-stent restenosis was evidenced in 28 stents (31.5%) by QAC. The sensitivity, specificity PPV and NPV of DSCT-CA for the diagnosis of in-stent restenosis was 89%, 87%, 76% and 95%, respectively. Diagnostic efficiency was not affected by heart rate and the sensitivity was 0.94 vs. 0.82, the specificity 0.88 vs. 0.90, the PPV 0.76 vs. 0.75 and the NPV 0.97 vs. 0.93 (all P > 0.05) between patients with heart rate < 70 beats/min and patients with heart rate ≥ 70 beats/min. The sensitivity (84% vs. 100%), specificity (81% vs. 96%), PPV (70% vs. 90%) and NPV (91% vs. 100%) were similar between overlapping or bifurcations stents and single stents. The specificity (100% vs. 80% vs. 66%) and PPV (100% vs. 95% vs. 53%) were significantly higher in the groups with stents ≥ 3.50 mm, stents 3.00 mm than in stents ≤ 2.75 mm (both P < 0.05).

CONCLUSIONDiagnostic efficiency of in-stent restenosis with DSCT-CA in the large diameter stent is better than in the small diameter stent and the diagnosis efficacy is not affected by heart rate and stent distribution.
