Objective To investigate the emergency treatment and correlation factors of aqueous misdirection during glaucoma and cataract surgery in glaucoma patients.Design Retrospective case series.Participants 126 cases(132 eyes)of angle-closure glaucoma patients with aqueous misdirection during surgery,100 cases(100 eyes)of angle-closure glaucoma patients without aqueous misdirection during surgery and 100 cases(100 eyes)of senile cataract patients.Methods We performed pars plana vitreous water-bag aspiration or anterior vitrectomy on glaucoma patients with aqueous misdirection during surgery.All the factors in observation group and control groups were compared and analyzed by logistic regression.Main Outcome Measures Preoperative highest intraocular pressure(HIOP),intraocular pressure after maximum dose(IOP),anterior chamber depth(ACD),lens thickness(LENS),axial length (AXL),mean keratometry(K),intraocular lens diopter within-0.5D corrected by SRK-T formula(IOLD).Results Among all the 132 angle-closure glaucoma eyes whose posterior chamber pressures were increased during surgery,we performed pars plana vitreous water-bag aspiration in 123 eyes(93.18%),and anterior vitrectomy in 9 eyes(6.8%).Postoperative complications included shallow anterior chamber in 20 eyes(7 eyes with malignant glaucoma,9 eyes with choroidal detachment,4 eyes with delayed local suprachorodal hemorrhage),and vitreous local hemorrhage in 1 eye.Means of all the observation indexes on three groups showed significant difference(all P
5. Treatment of intracranial arterial lesions with covered stents
Chinese Journal of Cerebrovascular Diseases 2006;3(9):388-394
Objective: We present our preliminary experience on the treatment of intracranial arterial lesions with covered stent in a series of patients. Methods: 20 patients have been treated by using Jostent coronary covered stent deployed in the parent artery across the lesions, which included aneurysms, iatrogenic or traumatic arterial injury, and traumatic carotid-cavernous fistula (TCCF). The profile of stent was determinded with the diameter of parent artery and the length of lesion. 5 cases of intradural vertebral aneurysms, 7 internal carotid artery (ICA) aneurysms (1 petrous, 2 cavernous, 2 ophthalmic, 2 supracliniodal segment), 1 iatrogenic ICA injury, 3 traumatic ICA aneurysms, 3 traumatic carotid cavernous fistula and 1 ICA cavernous segment stenosis with spontanous CCF were treated. 21 Jostent covered stent had been used. Combination of bare stent and covered stent were used in 3 cases. Results: Technical success were achieved in 17 cases. Each case had one lesion. Lesions were excluded from circulation in 14 cases. There were 3 cases with lesion reminants or endoleakage just after treatment, but disappeared soon in the follow-up angiography. No complication was found in successful cases. Covered stent deployment were failed in 3 cases. One had transient slight paraplegia. There was no severe complication or death. Conclusion: Excluding the lesion from circulation with covered stent has been proved to be an effective reconstructive treatment of intracranial arterial lesions. Further research and development are needed to make the indication even broader.

Objective To investigate the expression of aquaporin-3 (AQP3) in tongue tissues of rats with experimental severe acute pancreatitis (SAP) and regulating effects of emodin. Methods Rat models with SAP were established by injecting 5% sodium taurocholate retrogradely into gallbladder and pancreas. SD male rats were randomly divided into sham-operation group, model group, and emodin group. After model establishment, rats in the emodin group received gavage with emodin 20 mg/kg each day, while rats in the model group and sham-operation group received gavage with normal saline. The mental state, thick greasy tongue fur and mortality of rats were observed every day after model establishment, and 5 days later, protein and genetic expression of AQP3 were detected by Western blot and RT-PCR. Results Compared with the model group, the mortality and the thick greasy tongue fur significantly decreased, the protein and genetic expression of AQP3 significantly decreased in the emodin group (P<0.05). On the 5th day, 11 rats in the model group survived, and 5 rats had thick greasy tongue fur. Compared with the sham-operation group, the protein and genetic expression of AQP3 in the model group were higher (P<0.05). Conclusion Emodin can improve the severity of SAP and decrease the incidence of thick greasy tongue fur significantly by reducing the protein and genetic expression of AQP3.

Objective To explore the clinical value of the duplex ultrasonography (duplex US) for evaluating the re-stenosis after peripheral arterial bypass grafting. Methods Eighty prosthetic grafts of sixty-three patients with femoral-pop-liteal arterial bypass grafting were follow-up regularly by duplex US. They were divided into non significant stenosis group (n=56), the significant stenosis group (n=15) and occlusion group (n=9) according to the tube diameter and arterial blood flow-ing parameters, which changed postoperatively. The diagnostic results were compared and analyzed between duplex US and digital subtraction angiography (DSA). The peak flow velocity of middle grafts (MG) to 40 cm/s was defined to evaluate risk of graft occlusion. Results The diagnostic coincidence rate of duplex US and DSA for grafts stenosis classification was 90%. The diagnostic sensitivity of duplex US to grafts stenosis was 91.7%, and the specificity was 92.9%. The positive pre-dictive value was 84.6%for grafts stenosis, and the negative predictive value was 96.3%, the false positive rate was 16.7%, and the false negative rate was 8.3%. The grafts occlusion rate was higher in MG<40 cm/s group than that of MG≥40 cm/s group. Conclusion There was a good consistency with Duplex US and DSA for the diagnosis of peripheral artery bypass graft restenosis. Duplex US showed characteristics of non-invasive, simple and easily accepted by patients.

Objective To optimize human acellular dermal matrix(ADM) and evaluate its biological characters. Methods Human skin was treated with hypertonic saline followed by NaOH maceration(group A), hypertonic saline followed by sodium dodecyl sulfate (SDS) detergent(group B) or Dispase Ⅱ followed by Triton X-100(group C), the resulting ADM were sectioned, and then were stained by special immunohistochemistry method. The cytotoxicity of them were evaluated by methyl thiazolyl tetrazolium (MTT) colorimetry and then cell compatibility was analyzed by cell culture;The optimized ADM resulted was choosen for use. Fibrablasts(FBs)were transfected with adenovirus vector encoding green fluorescent protein gene(Ad-GFP)and the growth of them on the optimized ADM was observed by fluorescent microscopy. Results Collagen and elastic fibers can still be observed in three kinds of ADM. The cells in dermis can be disintegrated both in group A and C, but not in group B. The cytotoxicity scores of the ADM prepared in group A and B were grade 0 or grade 1, while that of group C was more than grade 1.The ADM prepared by NaCl-NaOH maceration had good biocompatibility. There was statistical difference in adhering number of NIH3T3 cells in group A and B. NIH3T3 cells grew well in group A and the resulted ADM was optimized. FBs transfected with Ad-GFP grew well in the optimized ADM. Conclusion The ADM prepared by NaCl-NaOH maceration was a good tissue engineering biomaterial with a little cytotoxicity and rich in resouce.
