?Ocular trauma related glaucoma is one of secondary glaucoma, which can lead to serious visual loss. According to the complex clinical findings and pathogenesis of ocular trauma related glaucoma, we divide traumatic secondary glaucoma into hyphema related glaucoma, angle recession related, lens injury related, adhesion and proliferation related. The treatment of secondary traumatic glaucoma with ocular trauma were different, specific treatment measures should be given according to the specific case to protect visual function.

Objective To investigate the value for the level mensuration of von Willebrand factor antigen (vWF:Ag) in stroke risk assessment in the patients with non-valvular atrial fibrillation (AF).Methods 180 non-valvular AF patients were selected from the Tianjin medical university general hospital from the 2009 to 2011 for retrospective cohort study,112 males and 68 females in the group,age 61-87 years.Using the IL ACL-9000 blood coagulation instrument assay the level of vWF:Ag.Using ROC curve to analyze the diagnosis performance of vWF:Ag,using Cox regression analysis model to evaluate the of vWF:Ag effect on prognosis,using x2 test to analyze the relevance between vWF:Ag and clinical pathological factors.Compared the patients group with CHADS2 score with the patients group with CHA2DS2VASc score date using t test.Results vWF:Ag levels were control group (112 ± 34)％,paroxysmal AF group (119 ±31)％,the persistent AF group (179 ± 47)％,permanent AF group (217 ± 56)％,atrial fibrillation associated with stroke group (235 ± 104)％ respectively.There was no difference between the paroxysmal AF group and control group (q =1.75,P ＞ 0.05) ; vWF:Ag level was higher in persistent atrial fibrillation group than in paroxysmal AF group (q =10.10,P ＜ 0.01); permanent atrial fibrillation group was higher than that of the persistent AF group (q =5.21,P ＜ 0.01).The optimum cut-off point with vWF:Ag for stroke diagnosis was 188.5％,the area under ROC curve =O.843 (95％ confidence interval:0.785-0.901).In Cox regression multianalysis,the vWF:Ag (HR =0.405; 95％ CI =0.268-0.716; P =0.026),the congestive heart failure(HR =2.901 ; 95％ CI =1.837-3.951 ; P =0.001),stroke/transienl ischemic attack (HR =4.665 ; 95 ％ CI =2.837-7.291 ; P =0.000),age (HR =0.474 ; 95 ％ CI =0.211-0.765; P =0.039),the Cox analysis showed that vWF:Ag was the independent prognosis factor for stroke in AF patients.Inx2 analysis,there was the relationship between the level of the vWF:Ag and the congestive heart failure/LVdysfunction (x2 =8.227,P ＜ 0.01),hypertension (x2 =3.305,P ＜ 0.05),age (x2 =7.581,P ＜ 0.01),diabetes mellitus (x2 =6.730,P ＜ 0.01),stroke/ transient ischemic attack/thromboembolism (x2 =4.825,P ＜ 0.05),vascular disease (x2 =4.126,P ＜ 0.05).Compared the subjects with CHADS2 (score =1) with the CHA2DS2VASc(score =1),the level of the vWF:Ag was higher in patients with CHADS2 score =1 (t =4.283,P ＜ 0.01).Conclusion There was relationship between the level of vWF:Ag and main pathologic factors in patients with AF,and changed with the condition,high vWF:Ag level was an independent predictor of stroke risk,and had superior reference value for in assessment of stroke in patients with atrial fibrillation.

Wnt signals widely exist in live creatures,involved in many physical or pathological processes,including the cell prolif-eration, differentiation and apoptosis. Recent studies show that Wnt/β-catenin signaling pathway may play an important regula-tory role in the protective effects of neurovascular unit in ische-mic stroke. Some chemicals,such as sulindac and estradiol,and some compound traditional Chinese medicine which contains gly-coside( e. g. rhodiola rosea ) , volatile oil ( e. g. turmeric ) and compound prescription ( e. g. Dan Long Xing Nao Fang ) can protect the neurovascular unit by regulating the pathway. This aims to review the research progress of the protective effects of Wnt/β-catenin signaling pathway on the neurovascular unit in is-chemic stroke,with combination of chemicals and traditional Chi-nese medicine which can protect the neurovascular unit via Wnt/β-catenin signaling pathway. It aims to provide the methodology basis for elucidating the mechanism of drugs,and also provide a new idea for researching the new drug which can reduce the dis-ability rate caused by sequela of stroke.

Objective To explore the effects of improved preparation before urodynamic examination in the elderly patients with voiding disfunction.Methods Totally 424 elderly patients underwent urodynamic examination after improvement of the preparation approach according to pathophysiological characteritics of the elderly patients,and 248 elderly patients before the approach improved in our center were collected as control.The compliance,discontinuation and repetition rate of urodynamic examination were compared between the two groups.Results The compliance of patients who used the improved preparation approach was significantly higher than control (92.5％ vs.59.3％,x2=106.428,P＜0.001).Whereas the discontinuation and repetition rates of urodynamic examination in the improved group were decreased as compared with control group ( 1.2％ vs.6.9％,x2 =14.176,P=0.0002; 8.5％ vs.21.4％,x2 =21.487,P＜0.001).Conclusions The improved preparation approach according to the pathophysiological characteritics of elderly patients is worthy to popularize in the urodynamic centers.

Objective To investigate the voiding patterns of term and preterm newborns and whether voiding in term and preterm neonates was accompanied by any cortical arousal. Methods Between May 2013 and September 2013,64 hospitalized newborns at Neonatal Intensive Cave Unit in the Frist Affiliated Hospital of Zhengzhou University were recruited in this study. In these patients,31 cases were term newborns(20 male,11 female)and 33 cases were preterm newborns(19 male,14 female). The term and preterm newborns gestational ages at birth were(38. 2 ± 1. 2) weeks and(32. 1 ± 1. 6)weeks,weighted(3. 3 ± 0. 4)kg and(1. 7 ± 0. 3)kg,respectively and postnatal ages at study were[4 - 16(10. 5 ± 3. 6)]days and[4 - 16(11. 2 ± 3. 1)]days. The voiding volume(VV),post - void residual volumes(PRV),body movement rate and voiding frequency(VF)in 4 hours as well as the volume of milk and liquid fed at the same time frame were recorded and analyzed,retrospectively. At the same time electrocardiogram(ECG)and electroencephalogram(EEG)were recorded. The changes of heart rate(HR),EEG frequency,respiratory frequency (RF)during the 5 s period and 30 s before and after voiding onset were compared respectively. For cortical arousal definition the recommendations of the International Pediatric Work Group on Arousals(2005)were used. Results A total of 184 times of voiding were recorded. In preterm newborns,the VV and body movements rate were significantly lower compared with the term newborns[(21. 8 ± 7. 9)mL and(41 ± 21)% vs(26. 4 ± 8. 7)mL and(62 ± 19)% , t = 3. 75,4. 20,all P ﹤ 0. 05]. However,the VF and PRV were significantly higher in preterm newborns[(1. 7 ± 0. 9) mL and(3. 2 ± 1. 1)times vs(1. 2 ± 0. 7)mL and(2. 6 ± 0. 9)times,t = 2. 47,2. 38,all P ﹤ 0. 05]. Bladder voiding in these infants happened only during QS. In term newborns,HR frequency was higher during the 5 s interval before and after voiding onset when compared with the 30 s period before voiding onset[(152 ± 6)times/ min and(152 ± 5) times/ min vs(147 ± 6)times/ min,t = 5. 30,5. 76,all P ﹤ 0. 05]and the EEG frequency[(2. 6 ± 0. 1)Hz and (2. 6 ± 0. 1)Hz vs(1. 5 ± 0. 1)Hz,t = 70. 0,70. 0,all P ﹤ 0. 05]. While the HR and EEG frequency of preterm neo-nate was not changed before and after bladder voiding onset. The RF of both term and preterm neonates were not changed before and after bladder voiding onset. Conclusions The voiding patterns between term and preterm were sig-nificantly different and cortical arousal was found only in term neonates,which indicate the term newborns have better mature bladder function and development of nervous system.

Objective To compare the efficacy of continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) on polycystic kidney disease (PKD) patients with end-stage renal disease (ESRD). Methods Retrospective analysis was made on 29 patients with PKD who carded out dialysis therapy for over 3 months in our department from January 2001 to December 2007. They were divided into the CAPD group (10 cases, 34.5%) and HD group (19 cases, 65.5%). Ten cases of non-PKD CAPD patients were randomly selected as the control, who matched the CAPD group in terms of age and gender. The patient information was recorded, such as general data, initial dialysis data, comphcations, survival time, quit of dialysis or death, etc. Kaplan-Meier method and Log-rank test were adopted to analyze the survival rate. Results The survival rates of 1-, 3- and 5-year for the CAPD group were 90%, 75% and 25% respectively, while for the HD group were 94.4%, 67.6%, and 48.3%, and for the control were 83.3%, 44.4% and 22.2% respectively, with no significant differences among 3 groups (P>0.05). group and the control were quite similar. The incidence of peritonitis for the CAPD group (0.62 times/patient year) was similar to that for the control (0.30 times/patient year)(P>0.05). The duration of the lust peritonitis[(23.5±4.0) months vs (20.0±15.8) months] and the catheter exit-site infection (0 time vs 1 time) for two groups were similar as well (P>0.05). One patient had hernia in CAPD group and no patient in control group had hernia. The incidence of peritoneal dialysate leakage was similar between these two groups. In the HD group, two patients (10.5%) had cerebral hemorrhage resulting in death, and 10 patients (52.6%) had cystic hemorrhage, 5 out of whom underwent operation due to repeated cystic hemorrhage and 2 cases received unilateral nephrectomy because of severe hemorrhage. No patient in CAPD group had cerebral hemorrhage but 1 patient (10%) had cystic hemorrhage and recovered after conservative treatment. The hemorrhage complication incidence of CAPD group was significantly lower than that of HD group (P<0.05). Conclusions The prognosis and complication incidence in PKD and non-PKD patients treated with CAPD are similar. The prognosis of PKD patients treated with CAPD or HD is also similar, and the risk of hemorrhage complications of PKD patients treated with CAPD may be decreased compared with those treated with HD. PKD patients can choose HD or PD as the initial therapy of ESRD unless existence of hernia or intolerance. PKD is not the contraindication of PD.
