Objective　To investigate the effect of turning scleral flap of self-body over drainage in trabeculectomy.Methods　The surgery was performed on one eye of a rabbit while　the other eye of the same rabbit was conducted with the routine trabeculectomy as the control group. The filtering bleb, intraocular pressure and pathology were observed. Results　The intraocular pressure in the experimental eye was much lower than that in the control group 3～12 weeks after the operations (P＜0.05).As it was within 2 weeks after the surgeries, but there was no significant filtering difference (P＞0.05).The rate of eyes with functional bleb in the experimental group was significantly higher than that in the control group at the postoperative 2～7 weeks .Conclusion　This study suggests the turning of self-body over drainage surgery can help to maintain filtering function for a long time and to prevent complication after filtering surgery.

To investigate the expression of Toll-like receptor (TLR) 2 and 4 mRNA in local tissues of model of oropharyngeal candidiasis in mice and to explore the potential role of TLR2 and TLR4 in earlier period of immune response, a murine model of oropharyngeal candidiasis inoculated by cotton wool balls saturated with Candida albicans was established. Mice were sacrificed at the indicated time points and the oropharyngeal tissues were excised. The expression of TLR2 and TLR4 mRNA was detected by RT-PCR. The results showed that low level of TLR2/4 mRNA could be detected in oropharyngeal tissues, but they were markedly up-regulated 6 h after inoculation, peaking after 12-24 h. Tissue TLR4 mRNA was gradually down-regulated 24-48 h, while TLR2 mRNA levels remained high up to the 72nd h. These data suggested that oropharyngeal infection of Candida albicans could result in up-regulation of TLR2/4 mRNA expression in local tissues, which might play important roles in earlier period of immune response.

Objective The aim of this study is to retrospectively analyze perioperative managements of very-low-birth-weight(VLBW) preterms with hemodynamic significant patent ductus arteriosus (hsPDA).Methods Between January 2006 and December 2011,totally 22 VLBW preterms with hsPDA underwent surgical ductal ligation.There were 12 boys and 10 girls.The median gestatianal age was 29 weeks (24 + 5-32 +6 weeks).The birth weight was (1103 ± 228) g(640-1440 g).The Apgar score was 6.1 ± 2.2 at 1 minute,8.6 ± 1.2 at 5 minutes.The average ductal size was (3.79 ± 1.01)mm (2.0-5.9 mm)、(2.69 ± 0.84) mm/kg(1.23-4.23 mm/kg),left atrial diameter to aortic root ratio(LA:AO) was 1.69 ± 0.41.The median weight at surgery was 1500 g(640-2100 g),average (1512 ±539) g.The median age at surgery was 24 days (11-167 days).Results 1 case death because of anesthetic accident.The average hospitalization days were (67.1 ± 36.1) days.The days of ventilation treatment after surgery were 2-44 days,15 cases (68.2％) weaned from mechanical ventilation within seven days after surgeries.The complications includes pulmonary hemorrhage (18.2％),necrotizing enterocolitis (13.6％),septicemia(22.7％),broncho-pulmonary dysplasia (63.7％),brain injury(18.1％),retinopathy of prematurity (31.8％),pneumonia (86.4％) and metabolic acidosis (45.5 ％).Conclusion For VLBW preterms with hsPDA,early diagnosis and early interfere are key points.Surgical PDA ligation is a promising option to avoid severe complications when medical treatments are ineffective.

ObjectiveTo analyze the status of DACH1 gene promoter methylation and explore its association with the expression of DACH1 gene promoter methylation and clinical significance of endometrium carcinoma(EC).Methods From February 2004 to August 2008,a total of 80 EC tissue samples with comprehensive surgical pathology staging were collected and used for this study.Twenty normal endometrium tissues in 2008 were abtained from the fractional curettage because of dysfunctional uterine bleeding as control.All samples were confirmed pathologically.Methylation specific PCR (MSP) was performed to detect the promoter methylation of DACH1 gene,and analyze its influence on the expression of DACH1 and the relationship between DACH1 promoter methylation and clinicopathological factors in EC.DACH1 protein expression was detected by western blot.Chi-square test and Pearson test were used for statistical analysis.ResultsThe rate of promoter methylation of DACH1 gene in the EC tissues was significantly higher than that in the normal endometrium issues (30％ vs.5％,P ＜ 0.05).There was an association between the expression of DACH1 and DACH1 gene promoter methylation ( r =- 0.30,P ＜ 0.01 ).There was statistical difference between the methylation of DACH1 and the pathological grade ( P ＜ 0.05 ) or histological type ( P ＜0.05).But DACH1 gene methylation was not related with the age,stage,myometrial invasion depth and lymphnode metastasis (P ＞ 0.05 ).Conclusions DACH1gene promoter methylaion could lead to a decrease or absence in the DACH1 expression in EC.The promoter methylation of DACH1 gene may induce the inhibition of DACH1 expression,which might be one of the mechanisms of DACH1 gene inactivation in human EC.

Objective To summarize primary experiences of integrated fetal diagnosis and postnatal treatment for the transposition of the great arteries (TGA). Methods Five fetus were diagnozed as TGA at(28.4 ±4.4) weeks of gestation via fetal echocardiography. The mean age of the pregnant women was (28.4 ±3.0) years old. Delivers were taken by caesarean at (36.5 ±1.8) weeks of gestation. The body weight of neonates was (2468 ±442) grams. All neonates were transported to the department of neonatology and re-checked by echocardiography. 3 cases were TGA with intact ventricular septum, 2 cases were TGA with ventricular septal defect. Prostaglandin and mechanical ventilation were applied if oxygen saturation was lower. The standard arterial switch procedure was performed under cardiopulmonary bypass with moderate hypothermia. Results The mean age for patients at surgery was (9. 0 ±6. 2) days ( ranged 2-19 days). Three neonates survived, 2 preterm neonates died. One with body weight 1770 g, 2 days after operation was died of sudden heart arrest and failure of resuscitation. Another was treated by mechanical ventilation and prostaglandin after delivery and underwent operation at the second postnatal day, the neonate appeared low cardiac output and high serum lactate postoperatively and died in the third day. Conclusion The integrated fetal diagnosis and postnatal treatment for TGA could prevent severe cyanosis and emergency transportation after parturition. The lack of any link in the cooperation among the multidisciplinary team could affect the benefits for the TGA neonates provided by prenatal diagnosis.

Objective To find out the present situation and influence factor in core capabilities of nurses of blood purification, and offer reference frame for evaluation, selection, authentication and engagement of nursing post. Methods Core capability training module for nurses of blood purification was selected as theoretical basis for rough draft of evaluation index system establishment. The selected index underwent expert consultation with Delphi method. Results Four hierarchy were confirmed after 3 rounds of consultation (N1-1,N 1-2, N2, N3). Each hierarchy had three evaluation indexes, knowledge, technology and clinical practice. Number of grade one evaluation indexes of each hierarchy was 5,5,4; 5,5, 4;5,5,5; 5,5,1. Number of grade two evaluation indexes was 20,20,24;20,20,20;25,25,48;23,24,14.Only N1- 1,N1-2 and N2 had grade three evaluation indexes, 16, 5, 13 respectively. Conclusions Preliminary establishment of core capability evaluation index system can basically evaluate capability of nurses of blood purification.

In order to study the susceptibility of murine vaginal mucosa to Candida albicans under different conditions, vaginal lavage fluid and vaginal tissue of mice were observed and compared between murine models with normal immune system (estrogen-treated mice) and immunosuppressed murine model, and between primary infection model of vaginal candidiasis and secondary infection one. The average level of colony forming unit (CFU) from the immuosuppressed group was higher than that from estrogen-treated group at each time point and the peak time was delayed. The differences between the two groups were statistically significant (P < 0.05) from the fourth day after inoculation. A significant difference existed in the average level of CFU between the control group and the estrogen-treated group (P < 0.05), and between the control group and the immuosuppressed group (P < 0.01). It was concluded that the vaginal mucosa from the immunosuppressed mice is more susceptible to Candida albicans and no difference is found in susceptibility between mice with primary infection and secondary infection.
