The angiotensin converting enzyme (ACE) gene is one of the main candidate genes of the genetic predisposition study of stroke,however,the correlation between the ACE gene polymorphism and stroke remains controversial.This article reviews the advances in research on the correlation between the ACE gene polymorphism and stroke in recent years.

Objective To explore the clinical feature,treatment and prognosis of neonatal small intestinal atresia.Methods Retrospective study was carried out of 80 neonatal small intestinal atresias over the last 14 years,including diagnosis,treatment and prognosis.Results Of them,62 cases were healed(77.5%),18 cases were dead(22.5%),24 cases(30%)associated with other anomalities.The living cases were followed up for 6 months to 3 years.These symptoms had not relapse.Conclusions Satisfactry effect can be obtained by early diagnosis and operative treatment.Sonography is an ideal way for early finding intestinal atresias in a fetus.End-to-end single layer anastomosis is an ideal way for monointestinal atresia,and poly-end-to-end single layer anastomosis plus long gastrointestinal silicone tube for supporting is an ideal way for multipal intestinal atresia.

ObjectiveTo assess the value of stent-assisted angiopl asty in the treatment of extracranial carotid stenosis.Methods A total o f 164 cases of ex tracranial carotid stenosis from October 2000 to December 2002, including 146 ca ses of carotid bifurcation stenosis, 13 cases of extracranial internal carotid s tenosis, and 5 cases of common carotid stenosis, were treated by self-expandable stent placement and angioplasty.ResultsStent placement and angioplasty was successfully accomplished in all the 164 patients. The degree of stenosis was re duced from (78 8?13 6)% before the treatment to (10 2?7 5)% after the oper atio n. There were 1 case of transient ischemic attack (TIA) (0 6%) and 1 case of mi n or stroke (0 6%) during the peri-operative period, but no death or major stroke took place. Follow-up for 3～30 months (mean, 8 9 months) in 145 cases found no T IA, cerebral apoplexy or death. Forty-five patients were followed by digital sub traction angiography (DSA) 6 months after the treatment, and asymptomatic re-ste nosis occurred in 1 case (2 2%).ConclusionsEndovascular ste nt-assisted angio plasty for extracranial stenosis is safe and effective, with favorable short-ter m outcomes.

Objective To establish a model of bone cancer pain in rats and to evaluate the role of voltage gated sodium channel Nav1.8 in the course of bone cancer pain by observing the expression of Nav1.8 in dorsal root ganglion in the model with bone cancer pain.Method Female SD rats received intra-tibial injection of syngenetic Walker256 mammary gland carcinoma cells in different concertration(103/?l,104/?l or 105/?l).Pain threshold of mechanical hyperalgesia and thermal hyperalgesia were tested at 1d,3d,5d,7d,10d,and 14d after cell injection.The development of the bone tumor was verified by pathological examination 14d after cell injection.The L5-6 DRG was obtained from normal rats and rats with bone cancer pain.Expression of voltage gated sodium channel Nav1.8 was investigated by RT-PCR.Result Intra-tibial injection of Walker256 cells produced a rapidly expanding tumor within the boundaries of the tibia,causing marked remodeling of the bone.Rats receiving intra-tibial injection of Walker256 cells displayed gradual development of both mechanical and thermal hyperalgesia 7-14 days after the injection.The expression of Nav1.8 in DRG was up-regulated in the model of bone cancer pain in rats(P

Objective To study the urban elder people's cancer-spectrum in Chongqing from 1991 to 1998 in order to obtain the first-hand data and references for the prevention and the treatment of carcinoma in the seniles. Methods The data of population and death causes were collected with cluster sampling method in the communities of business, culture and industry in Chongqing. Their mortality rate, disease-specific mortality rate and the sequence of the death causes were analyzed. Results Their first death causes was cancer (mortality rate 811.95/105 persons, accounted for 21.25% of all death causes). The mortality rate of five cancers was as follows: lung cancer (282.45/105), esophagus cancer(119.47/105), liver cancer(108.41/105), stomach cancer (73.75/105) and intestine cancer (55.31/105). The prevalence of different cancer between male and female at different communiteis was different. Conclusions It is very important to strengthen the protection of the environment and advocate the healthy life mode in order to lower the mortality rate by cancer in urban seniles.

Objective: To summarize the experience in the treatment of candidiasis albicans. Methods: 95 cases aged 5 months～78 years old with candidiasis albicans were treated by fluconazole and polyactin A etc, the Candida albicans were examined by smear examination.Results: The rate of cure was 35.79 %, that of improvement was 57.89%, the clearance rate of Candida albicans was 80.59%.Conclusion: The Cadida albicans is opportunistic pathogen. Fluconazole is effective in the treatment of candidiasis albicans.

Objective Endovascular stenting or combined stenting and Guglielmi detachable coils packing for the treatment of intracranial fusiform and wide necked aneurysms were reported to access the feasibility of the procedures.Methods The coronary stents were implanted across the neck of 3 vertebral fusiform aneurysms and 6 wide necked aneurysms. Microcatheters were introduced into the aneurysm sacs through stent mesh, and finally GDCs were used to embolize the aneurysms. Results The stents were precisely deployed resulting in total occlusion of 7 cases with more than 90% occlusion in 2 cases. All patients recovered well with patency of the parent arteries.Conclusions Endovascular therapy with combined stent implantation and microcoil placement maybe a valid alteration for the treatment of intracranial fusiform or wide necked aneurysms.

Objective To analyze the causes, prevention and treatment of repture druing procedure for intracranial aneurysm embolization with GDC.Methods All the seven patients were embolized. Six patients were ruptured during the procedure and continuously embolized until the bleeding was halted. Another one was identified by post procedure CT. Results Four patients recovered unevent fully with one only suffering from mild deficit. Another 2 patients died of hyper intracranial pressure within one week. Conclusions Rupture during procedure of intracranial aneurysm embolization with GDC may be related to manipulation, properties of the parent artery and arneurysm. Continuous embolization with GDC will provide favorable prognosis for the patients.

Objective To evaluate the endovascular embolization treatment of large and giant ophthalmic aneurysms. Methods Three aneurysms were embolized with coils only and 5 aneurysms were treated with stent placement togather with subsequent coiling. Results In the 3 aneurysms treated only with GDC, total embolization was achieved in 1 and partial embolization in 2. In the stent placement and coiling case, 4 aneurysms were densely packed and another one was partially packed. Conclusions Combined stenting and coiling is effective and safe for the treatment of large and giant ophthalmic artery aneurysm with the preservation of parent artery.
