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.

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.

·AIM: To study the therapeutic effect of surgical treatment for traumatic cataract.·METHODS: Seventy-three cases(73 eyes) traumatic cataract were performed multi-operation combined cataract extraction, including insertion of a capsular tension ring(CTR), vitreoretinal surgery, ocular foreign body extraction and intraocular lens(IOL) implantation.·RESULTS: Of 73 patients, twenty-seven cases were blunt trauma, while 46 cases were penetrating injuries. Three months after surgery, the final best spectacle-corrected visual acuity(BSCVA) in 5 patients (7%) were 0.05 or less, seventeen(23%) 0.05 to 0.3, while 49(67%) 0.3 or more. There were 93% cases relieved from blindness. Atrophy of eyeball occurred in two cases(3%). Mean follow-up time was 7.8(range 3-15) months.·CONCLUSION: Useful vision can be restored in a proportion of traumatic cataracts after prompt and rational surgical intervention as well as appropriate treatment of sight-threaten complications.

The risk factor of dental fluorosis are mainly related to the cancen tration of fluoride in the drinking water,the supplements of fluoride,nutrition states and regime,the time of fluoride exposure.Other factor such as the period of mother's milk feeding,the altitude of resident,the environmental pollution,the education degree of parents,and the level of health service of the community are also contributed to the development of dental fluorosis.Besides,the knowledge of dentists,the health habits of individual,the condition of economic,and so on is somehow the risk factor of dental fluorosis.The chances of fluoride exposure will become more often as the prosperous of the society.Thus any health policy of the complement of fluoride should be adapted to local conditions.

Objective:To understand the roles of PTHrP in the pathogenesis of temporomandibular joint after over mechanical loading. Methods:Fifteen adult New Zealand rabbits were subjected to traction between the mandibular ramus and zygomatic arch in the postero-superior direction unilaterally using elastic force. The rabbits were killed respectively at 2, 4 and 6 weeks and the histologic changes were observed by Hematoxylin & Eosin staining. The expression of PTHrP in the condyle of TMJ was observed by immunohistochemistry. Results:Stronger expression of PTHrP could be found in proliferation cell layers and upper hypertrophy cell layers in the early stage after operation, and weaker expression in mid stage, but stronger near the chondrocyte clusters. Conclusion:It is suggested that PTHrP might relate to the regeneration of condyle cartilage.

Objective The facial soft tissue features were studied in Urumqi adolescent with skeletal Ⅱ malocclusion by using a polar coordinate system. Methods Sixty samples of Urumqi adolescent with skeletal Ⅱ malocclusion were selected, each one underwent cephalometrics analysis and 32 cephalometric parameters from the samples were measured. The mean and standard deviations of each measurement were compared by statistical analysis (t-test). Results Polar distance in male was larger than female, showing significant difference between male and female. Po-Ns/Po-Li, Po-Ns/Po-Bs, Po-Ns/PoPgs, Po-Ns/Po-Gns, and Po-Ns/Po-Mes showed significant difference between male and female. Polar angles in female were larger than male, with a significant difference between male and female.Conclusion Statisticalstudies on features of facial soft tissue show significant differences between male and female. The polar coordinate analysis system is a good index to study the growth magnititude and direction of facial soft tissue during growth and development or before treatment and after treatment.

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.
