Objective To investigate the necessary and feasibility of fistulous tissue-saving anorectoplasty for low anorectal malformation with fistula in children.Methods The clinical data of 67 cases of low anorectal malformation with fistula were analyzed retrospectively, there were 59 girls with rectovestibular fistula, 8 boys with rectoperineal fistula. The patients′ average age were 10 months, ran -ging from 3 months to 16 years. The clinical manifestations of all patients were intractable constipation, or out of position of anus. Cut-back procedure had been performed on 4 patients in infancy. The anterior sagittal anorectoplasty was performed in all cases.Results In all cases returned for follow-up at 3 and 6 months after operation, the longest was 8 years. The postoperative course of 65 patiens was uneventful without wound infection, and had a normal-looking perineum, other 2 cases with anal rupture in operation were with sagittal wound infection resulted from perforation in repairing anus, and formed finally rectoperineal fistula with a normal-looking anus. Sixty-four cases (95.5%) had good continence by 5-6 score, another 3 cases (1 boy, 2 girls) with intractable constipation defecated with help of Glycerinum.Conclusions The fistulous tissue-saving anterior sagittal anorectoplasty is a reliable and feasible procedure for low anorectal malformation with fistula. This operation provides good results.

OBJECTIVETo investigate the efficacy of Chinese medicine Huangban Bianxing Recipe (HBR) for treatment of choroidal neovascularization (CNV).

METHODSEighty patients (97 eyes) suffered from CNV were assigned to two groups, the treated group treated by HBR orally taken one dose every day and the control group treated with ginkgo leaf tablet 1 tablet (19.2 mg) thrice a day, all for 3 months. The best corrected visual acuity (BCVA), fundus hemorrhagic area were measured; the neo-genetic vascular leakage area determined by fluorescent fundus angiography (FFA); and the out-layer high reflective band thickness (OHRBT) estimated by optical coherent tomography (OCT) were recorded before and after treatment.

RESULTSAfter treatment, in the treated group, BCVA was improved, with an effective rate of 67.12%, while in the control group, it was 33.33%, the former was better than the latter significantly (P < 0.05). The effective rate in reducing fundus hemorrhagic area in the two groups (85.11% vs 47.62%) and that in the CNV closure showed by FFA (67.50% vs 37.50%) were also superior in the treated group (P < 0.05). Besides, OCT showed that the OHRBT reduced significantly after treatment in the treated group (P < 0.01).

CONCLUSIONHBR can improve the vision, reduce the CNV leakage in the macular region, and advance the absorption of fundus hemorrhage in CNV patients.

Objective To establish a closed-chest pulmonary embolism-reperfusion animal model by Swan-Ganz catheter and to explore the mechanisms of pulmonary embolism(PE)-reperfusion injury(RI). Methods Experiments were made on 14 mongrel dogs,ranging in weight from 15 to 18 kg,anesthetized with 3% pentobarbital sodium.The dogs were intubated with I.D.7 endotracheal tubes.Under sterile conditions,a 7 F Swan-Ganz catheter via the external jugular vein was positioned in the unilateral pulmonary diaphragmatic lobe(DL)artery.Occlusion/reperfusion of the DL artery was controlled with 1.2 ml diluted contrast agent filled into/drawn from the balloon.After the 24 h PE,the balloon was deflated to result in 4 h reperfusion of the DL.Measurements of blood gases and tumor necrosis factor-?(TNF-?)were made at normal condition,at 24 h PE and at 4 h reperfusion.Thin-section CT scans were performed at normal condition,24 h PE,30 min,1,2,3 and 4 h reperfusion,respectively.At the end of each experiment, tissue specimens of bilateral diaphragmatic lobes were obtained for both wet/dry(W/D)weight ratio and for pathological study.Results Reperfusion pulmonary edema(RPE)was an acute,mixed,noncardiogenic edema that was observed in all 14 dogs who had been successfully established as PE/RI animal models.RPE demonstrated heterogeneous ground-glass opacifications that predominated in the areas distal to the recanalized vessels.It manifested pathologically as an edematous lung infiltrated by inflammatory cells.The mean ofPaO_2 and TNF-? of 4 h reperfusion was(81?4)mm Hg(l mm Hg=0.133 kPa)and(16.0? 2.5)pg/ml,which were significantly different(P

AIM: To explore the long-term efficacy of Q-factor guided laser epithelial keratomleusis ( LASEK ) for myopia and astigmatism with positive Q-factor.
METHODS: There were 158 eyes which were myopia and astigmatism with positive Q- factor taken in two groups randomly: 86 eyes accepted Q - factor guided LASEK as observation group and 72 eyes accepted routine LASEK as control group. The difference between the two groups about all data was similar. The uncorrected visual acuity ( UCVA ) and the best corrected visual acuity ( BCVA ) as well as diopter, ocular tension, corneal topography, Keratometry value K, aspherical factor Q, Higher-order aberrations ( HOA ) , corneal thickness by ultrasound and, contrast sensitivity ( CS ) , Haze were examined and compared before and after surgery. All the cased were followed up for 14d, 1, 3, 6, 12mo. And there were no statistical difference among the data before surgery.
RESULTS: After 12mo there were no statistical difference between the two groups about UCVA and BCVA. But the safety index of observation group was 1.10, that of control group was 1. 07. The validity index of observation group was 1. 06, that of control group was 0.99. The HOA of observation group was 0. 45±0. 17μm, and that of control group was 0. 72±0.25μm, there was statistically significant difference (t=-8. 193,P=0. 000). Q factor of observation group was 0. 41±0. 17, that of control group was 0. 77±0. 22, there was significant difference (t=11. 377,P = 0. 028). The contrast sensitivity of 3mo post surgery of patients in the observation group returned to the level of before surgery. But in the control group the contrast sensitivity of the patients did not returned until 6mo.
CONCLUSION:Q-factor guided LASEK for myopia and astigmatism with positive Q-factor is stable, safe and effective. The operation allow for reducing the high order aberrations, maintaining the most asphericity of cornea, saving more in corneal tissue, which cause faster recovery of contrast sensitivity, less haze and better visual quality.

Objective To evaluate the relationship between carotid plaque neovascularization and coronary heart disease using contrast-enhanced ultrasound. Methods We studied carotid plaques in 312 patients with coronary artery disease by contrast-enhanced ultrasound [51 patients with acute coronary syndrome (ACS) and 261 patients with stable coronary artery disease (sCAD) ]. We analyzed sonographic features of each plaque, including the enhancement intensity of plaque (A value), the ratio of plaque to carotid artery lumen in enhancement intensity (Ratio), plaque thickness and plaque echo (soft plaque, hard plaque, mixed plaque, calcified plaque). Results The average thickness of plaque in patients with ACS and in patients with sCAD had no significant difference in statistics [(2.6±0.4) mm vs (2.9±0.8) mm, t=-1.903, P=0.058) ]. The group with ACS:soft plaque 43 (84.3%, 43/51), mixed plaque 8 (15.7%,8/51), no hard plaque and calcified plaque. And the group with sCAD:soft plaque 174 (66.7%,174/261), hard plaque 19 (7.3%,19/261), mixed plaques 16 (6.1%,16/261), calcified plaque 52 (19.9%,52/261). The percentage of soft plaque in the acute coronary syndrome group was significantly higher than that in stable coronary artery disease group (χ2=6.274,P=0.012). The A value and Ratio in patients with ACS were prominently larger than those in patients with sCAD [ (11.3±3.2) vs (8.9±3.3) dB, t=7.150,P<0.01;0.6±0.2 vs 0.4±0.2, t=7.419,P<0.01].Conclusion Carotid artery plaque neovascularization density was significantly higher in patients with ACS than that in patients with sCAD by using contrast-enhanced ultrasound, revealing that the neovascularization density is closely related to clinical symptoms of patients with coronary heart disease.

PURPOSE: This study was conducted to investigate the relationship of self-resilience, academic self-concept and test anxiety in undergraduates. METHOD: The participants were 403 undergraduates in H, C University in G City, and K University in S City. Data were collected from March 1 to April 30, 2012, and analyzed using SPSS/WIN 18.0. RESULTS: The mean score per item for self-resilience was 2.77. The mean academic self-concept score was 3.17 and the mean score for test anxiety was 2.38. Self-resilience showed a negative correlation with test anxiety (r=-.186, p<.001) and a positive correlation with academic self-concept (r=.312, p<.001). Academic self-concept showed a negative correlation with test anxiety (r=-.353, p<.001). CONCLUSION: The findings of this study indicate that self-resilience and academic self-concept enhancement programs should be developed to reduce test anxiety in undergraduates and that further study should be done on the effects of such programs.
