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 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.

·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 investigate the clinical characteristics of neonatal tuberous sclerosis complex (TSC).Methods A total of 134 patients were admitted and diagnosed as TSC in Beijing Children′s Hospital,Capital Medical University from September 2006 to September 2015.The clinical characteristics of TSC in 8 patients who had clinical symptoms initiating from the neonatal period (skin lesion,neurologic abnormality,etc.) were analyzed,so as to conduct the auxiliary examinations (skin biopsy,ultrasonic cardiogram,cranial imaging) and the follow-up results.Results Among 8 patients,4 were diagnosed as TSC in the neonatal period while other 4 were diagnosed at later period from 4 months to 14 years old.Six patients had skin lesions in neonatal period,accounting for 75% of 8 patients,with predominant symptoms:hypomelanotic macules (5 cases),angiofibroma (2 cases),and shagreen patch (1 case).Cardiac abnormalities in neonatal period mainly included cardiac rhabdomyoma,which were characterized by high incidence,multi-regional occurrence,and wide distribution,noticed in 4 patients (50%).Ultrasonic cardiogram showed a mass in 4 patients with moderate-strong echo,uniform texture and clear boundary,and slight effect on tricuspid valve blood flows (in 1 case).Electrocardiogram abnormalities were found in 1 case,like atrial premature beats with intraventricular aberrant conduction,and accelerated atrial escape.Neurologic abnormality of neonatal TSC could present convulsive seizures.Cranial imaging lesions showed subependymal nodules (3 cases),leukodystrophy (2 cases),and giant-cell astrocytoma (1 case).Evidence for TSC2 gene positive and heterozygous mutation was identified in 1 case.The nucleic acid mutation site was at c.268C>T (E4),and the amino acid mutation was p.90Q>X.The mutant effect was nonsense mutation,which could lead to premature termination of protein translation.Conclusion The clinical characteristics of neonatal TSC may involve multi-system lesions,most commonly seen in the skin,cardiac,and ner-vous system.Neonatal physical examinations,cranial CT/magnetic resonance imaging and cardiac ultrasound screening should be done for the suspected TSC patients,and genetic diagnosis may contribute to the early diagnosis of the disease.

OBJECTIVETo compare differences of therapeutic effect between acupuncture method of tonifying-qi and dredging-meridian and conventional acupuncture method.

METHODSSeventy cases of blepharospasm were randomly divided into an observation group and a control group, 35 cases in each one. Cuanzhu (BL 2), Yuwei (Extra) through Yuyao (EX-HN 4), Xinming 1 (Extra), Sibai (ST 2) and Yintang (GV 29) were selected as main acupoints. The acupuncture method of tonifying-qi and dredging-meridian was applied in the observation group, which was an acupuncture manipulation that could achieve strong needling sensation of qi arrival combined with electric-impulse stimulation. The conventional acupuncture method was applied in the control group. The treatment was given once every other day, 10 times as a session for continuous three sessions in both groups. The severity of blepharospasm was compared before and after treatment in two groups and clinical therapeutic effect was assessed. Follow-up visit was performed after half a year to observe the recurrence rate.

RESULTSThe cured and markedly effective rate was 77.1% (27/35) in the observation group, which was superior to 51.4% (18/35) in the control group (P < 0.05). Among cured and markedly effective patients in both groups, the recurrence rate was 20.0% (4/20) in the observation group, which was inferior to 54.5% (6/11) in the control group (P < 0.05) in the follow-up visit.

CONCLUSIONThe acupuncture method of tonifying-qi and dredging-meridian could effectively improve severity of blepharospasm, which has superior short-term and long-term effects to conventional acupuncture method.

Objective We analyzed the incidence and treatment of symptomatic vasospasm after early endovascular therapy of ruptured aneurysms by endovascular embolization.Methods 329 patients classified as Hunt-Hess grades Ⅰto Ⅲ were embolized within 72 hours after aneurysm rupture. Symptomatic vasospasm was diagnosed as the onset of delayed neurological deterioration with evidence of angiographic or transcranial Doppler studies. Results Symptomatic vasospasm occurred in 62 patients (18.2%). Both Hunt-Hess grade and Fisher's scale before treatment correlated with the incidence of cerebral vasospasm. Among the 62 patients suffered from symptomatic vasospasm, 41 patients recovered well, 13 were moderately disabled, 6 were severely disabled and 2 patients died. Conclusions The incidence of symptomatic vasospasm was relatively low as compared to conventional open surgery. lumber puncture cerebral spinal fluid drainage may play an important role in reducing the incidence of cerebral vasospasm.
