AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

Objective To investigate etiology and clinical features of acute pancreatitis (AP) in young patients. Methods In total, 423 patients with AP admitted to Renmin Hospital of Wuhan University, Wuhan, Hubei province during January 2006 to December 2009 were retrospectively analyzed, 55 cases aged 34 years or less as young group and another 55 cases aged more than 34 years as middle- and elderly-age group. Their etiology, clinical features and illness scores based on some standard criteria were assessed. Results Proportion of varied etiologies of AP in young group was different from that in middle- and elderly-age one (x2 = 17. 107, P = 0. 009) , mainly as biliary and idiopathic pancreatitis in young group and as biliary and alcoholic pancreatitis in middle- and elderly-age one. Incidence of diet-related and idiopathic pancreatitis were higher in young group than that in middle- and elderly-age one ( x2 =4. 853, P = 0. 028 and x2=4. 274, P = 0. 039 ). Scores of the acute physiology and chronic health evaluation II ( APACHE II ) , Ranson criteria and the bedside index for severity in acute pancreatitis ( BISAP) were all lower in young group than those in middle- and elderly-age one (t = 5. 381 , P = 0. 000; t = 4. 388 , P = 0. 000 and t=3. 083, P = 0. 003 ) . There was no statistically significant difference in scores of computed tomography severity index ( CTSI) between young group and middle- and elderly-age one (t = ±0. 750, P > 0. 05 ) . Recurrence rate of AP was lower in young group than that in middle- and elderly-age one ( x2 =4. 251, P = 0. 039). Cholecystitis was more complicated in young group, pregnancy was more complicated in young group (x2 =4. 151 , P =0. 042) , and elevated blood glucose was more complicated in middle- and elderly-age one (x2 = 13. 285 , P = 0. 000 ) . Conclusions Etiology of AP varies in young patients with more dietary factors, occurrence of systemic complications and risks for death are lower in young group than those in middle- and elderly-age one, and there was no statistically significant difference in local complications and severity of illness between the two groups.

Objective To quantify the concentration of peripheral blood plasma neutrophil gelatinase-associated lipocalin (NGAL) in patients with acute pancreatitis (AP) and to explore its value in assessment of the severity of AP.Methods From June 2011 to March 2012,83 patients with AP were selected,among those 43 cases were mild acute pancreatitis (MAP) and 40 were severe acute pancreatitis (SAP).The control group included 30 healthy individuals.The peripheral blood of patients with AP and healthy controls was collected,and plasma was isolated after centrifuged.The concentration of NGAL in plasma was detected by enzyme-linked immunosorbent assay (ELISA).The t-test was performed for comparison between groups.The correlation between the concentration of NGAL in plasma and clinical parameters of AP was analyzed by Spearman rank order correlation analysis.The diagnosis value of the concentration of NGAL in SAP was evaluated by receiver operating characteristic (ROC) curve and area under the curve (AUC).Results The concentration of plasma NGAL in AP group ((10.30± 5.97)nmol/L) was higher than that in healthy control group ((1.94±1.35) nmol/L) and the difference was statistically significant (t=11.924,P＜0.01).The concentration of plasma NGAL in SAP group ((14.61 ±5.28) nmol/L) was higher than that in MAP group ((6.27±-3.09) nmol/L) and healthy control group,the differences was statistically significant (t=8.677 and 14.539,both P＜0.01).The concentration of plasma NGAL of AP patients was positively correlated with acute physiology and chronic health evaluation-Ⅱ score,Ranson score,bedside index for severity in acute pancreatitis score,computed tomography (CT) severity index,C-reactive protein,white blood cells and the days of hospitalization (r=0.651,0.556,0.514,0.620,0.320,0.458 and 0.346,all P＜0.05).The area under the ROC curve of plasma NGAL concentration in diagnosis of SAP was 0.926 (95％CI:0,870-0.983).The cutoff value of plasma NGAL level in diagnosis of SAP was 8.44 nmol/L.The sensitivity and specificity was 87.5 ％ and 88.9％,respectively.Conclusions Plasma NGAL level is correlated with the severity of patients with AP.NGAL may be one of the markers for the early diagnosis of SAP.

Aim To observe the effects of cytokine signaling inhibition protein-3(SOCS3) on the liver fibrosis progression and reverse.Methods C57BL/6 mouse model was established by subcutaneous injection of carbon tetrachloride(CCl4).After a successful model of fibrosis, one-month normal diet was given to induce the reverse fibrosis model, while normal mice of the same gender and weight were as control group.Mice were sacrificed at 1, 2, 3, 4, 5, 6, 7, 8 weeks, respectively, then the liver tissue was harvested for the observation of its injury by hematoxylin and eosin(HE) staining.Then Masson staining was applied for the detection of changes in collagen, and the immunohistochemistry(IHC) for the observation of type Ⅰ Collagen(Colla-1), alpha smooth muscle actin(α-SMA), transforming growth factor beta 1(TGF-β1) and SOCS3 protein expression.In vitro formation of fibrosis was induced by TGF-β1 stimulating HSC-T6 cell lines, which was then reversed by MDI medium, with co-incubation of HSC-T6 cells with plasmid in the process of the reverse.Western blot was employed to detect SOCS3, Colla-1, α-SMA, TGF-β1 expression.Results The expression of SOCS3 and TGF-β1 increased in mouse model of fibrosis with the worsening fibrosis process and decreased in the reverse process.Over-expression SOCS3 in the reverse process reduced the development of liver fibrosis;meanwhile, the expression of TGF-β1 was also reduced accordingly.Conclusion SOCS3 may influence the development of the liver fibrosis and its reverse via regulating the expression of TGF-β1.

Background Erythropoietin (EPO) was proved to be express in hematopoietic tissue and nervous system and play the effects of stimulating blood cell production and protecting nervous tissue.Researches showed that EPO is expressed in the embryon brain of animal.However,whether EPO exist in nervous-derived retina and its action on retina with the development is concerned. Objective This research was to investigate the expression of EPO during the embryonic development period of rat retina and explore the role of EPO in retina development process.Methods Clean Wistar rats with pregnancy for 12 days,16 days and 20 days were collected,and the embryonic 12-day rats (E12 d,5 rats),embryonic 16-day rats (E16 d,5 rats) and embryonic 20-day rats ( E20 d,5 rats) were obtained by caesarean operation,and 5 12-month W istar rats were used as controls.The rats were sacrificed by cervical dislocation and the retinal sections were prepared in the different-embryo-phase (12 d,16 d,20d) and growth phase.The expression of EPO protein and mRNA in rat retina was detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR),respectively.The feed and use of the animals followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results EPO was positively expressed in the cytoplasm and nuclei in the neuroepithelial layer and pigment epithelium of every-embryo-phase rats but only in retinal ganglion cell layer in 12-month-old rats.The gray scale values of EPO expression in retina were 105.55±10.35,99.35± 8.71,83.27± 7.84and 30.30± 3.80 in E12 d rats,E16 d rats,E20 d rats and 12-month-old rats respectively with a statistically significant difference (F=76.13,P＜0.01 ).RT-PCR revealed that the relative values of EPO mRNA expression in retina were 0.876±0.10,0.861 ±0.09 and 0.256±0.03 in E16 d rats,E20 d rats and 12-month-old rats respectively,presenting a elevated value in embryonic rats compared with adult rats ( P =0.00).Gel imaging deletion showed that the A value of EPO amplification products was highest in E16 d rats and lowest in adult rats.Conclusions The expression of EPO appears a high to low fashion during the embryonic development of Wistar rats,which is closely associated with the developing procedure of retina.

Objective The mortality rate of the children after surgical repair of congenital heart disease associated with acute renal injure has been reported to be 30％-79％.Peritoneal dialysis is the common treatment method for those patients,but the optimal time to initiate peritoneal dialysis is still controversial.The aim of this study was to investigate the clinic outcome of early peritoneal dialysis to the children following cardiac surgery.Methods We performed a retrospective chart of children following cardiac surgery from January 2008 to December 2009.The total number was 4561,62 of them were performed PD treatment.Data on the PD treatment children were collected from pre-operation to hospital discharge.Early peritoneal dialysis group was defintes as PD initiated at operation room or the interval between the end of operation to starting peritoneal dialysis less than 3hrs.the others were traditional PD group.Results The whole PD treatment rate was 1.36％,15 patients died.The mortality were 10.71％ (3/28) in early PD and 35.29％ (12/34) in conditional PD group respectively (P =0.036).2 patients were met RIFLE(risk,injury,failure,loss,and end-stage renal disease,RIFLE)classification as failure grade in early PD group while 10 patients in traditional PD group (P =0.001).After PD treatment 24hrs,the Vasoactive-Inotrope Scores and serum creatinine values were much lower in the early PD group children than those in the traditional PD group[(19.00 ±2.39) vs(37.00±5.22),P=0.002;(50.51 ±21.84) vs(130.13±76.09),P=0.001)].Conclusion This study shows that early PD can prevent the children after congenital heart surgery to develop AKI,and reduce the severity of the clinic status.Early intervention with PD is associated with low mortality.

Objective To investigate effect of serum apoptosis factor and long-term effect on medical abortion patients by sequential misoprostol. Methods 80 cases of early pregnancy patients who required termination pregnancy, were selected and randomly divided into 2 groups.40 cases in control group were treated with mifepristone 25mg oral, misoprostol 600μg, 4 times a day.40 cases in experiment group were treated with sequential use of misoprostol.Effect of medical abortion, survivin and caspase-3 were compared after 7d treatment.Gynecological inflammation, dysmenorrhea and infertility were compared for 2 years.Results Compared with control group, complete abortion rate of the experiment group was higher (P<0.05).The incidence of adverse drug reactions of the experiment group was lower than control group (P<0.05) after 2 years follow.up.Compared with the control group, HCG,E3 and P of experimental group were lower (P<0.05).After 7 days of medication,survivin decreased,caspase-3 increased,compared with control group, survivin of the experiment group was lower, caspase-3 was higher ( P<0.05 ) .Conclusion Misoprostol sequential can improve the success rate of medical abortion abortion, reduce the complications of abortion, presumably with the inhibition of survivin expression, is associated up regulation of caspase-3 levels.
