Objective To investigate the diagnosis of intracranial artery fenestration and its other vascular anomalies with CT angiography ( CTA ) . Methods The image data of 653 patients examined with head CTA and 39 patients diagnosed as intracranial artery fenestration in Zhongshan Hospital Affiliated to Sun Yat-sen University from January 2013 to January 2014 were analyzed retrospectively. The incidence, location,morphology of intracranial artery fenestration, and other vascular anomalies were analyzed. Results (1) In 653 patients,39 (5. 97%) with 41 artery fenestrations were detected. The detection rates of basilar artery fenestration was 3. 37% (n=22),vertebral artery fenestration was 0. 31% (n=2),anterior cerebral artery fenestration was 1. 22% (n =8),anterior communicating artery fenestration was 0. 61%(n=4),and middle cerebral artery fenestration was 0. 76% (n=5),respectively. The post-circulation fenestration was mainly convex lens type (66. 67%,n =17),the anterior-circulation fenestration was mainly fissure type (76. 47%,n=24),and there was significant difference (χ2=7. 411,P<0. 05). (2) In the 39 patients,22 complicated other vascular anomalies. Most of them were unilateral or bilateral fetal-type posterior cerebral arteries (n=10),and followed by aneurysms (n=5). The locations of 5 aneurysms were far from the fenestration,3 located in the communicating segment of internal carotid artery,1 in the top of basilar artery,and 1 in the M2 segment of bilateral middle cerebral arteries. Conclusion CTA can intuitively and clearly reveal the intracranial artery fenestration and other vascular anomalies. But there is no significant correlation between arterial fenestration and vascular anomalies.

Objective To understand the status of field feces in Jingzhou City, so as to provide the evidence for improving the control measures to interrupt the transmission routes of schistosomiasis. Methods The distribution of field feces was investigated in 27 schistosomiasis endemic villages in Gong’an,Jianli,Jiangling,Honghu and Shishou counties(cities)from 2010 to 2012. The schistosome positive status of the field feces was surveyed with the hatching method. Results There were 1 366 field feces and the average density was 0.089 2 feces per 100 square meters in this survey. The cattle feces,human feces,dog feces and elk feces respectively accounted for 99.71%,0.07%,0.15% and 0.07% in the survey. The infection rates of the field feces were 1.46%and 2.42%in the channels and bottomlands,respectively(P>0.05). The average rate of infected field feces was 3.21%in 2010,0.36%in 2011,and 1.60%in 2012,and the difference between 2010 and 2012 was not statistically significant(P>0.05). Conclusions The main field feces come from cattle,and the main distribution of infected field feces is in channels and bottom-lands. Therefore,the management of cattle and treatment of field feces should be strengthened.

Objective To evaluate the effect of the clinical nursing path integrated with the holistic nursing on advanced schistosomiasis patients with ascites. Methods A total of 226 advanced schistosomiasis patients with ascites were randomly di?vided into a control group and an experimental group (113 cases each group). The subjects in the experimental group were nursed by the clinical nursing path integrated with the holistic nursing,while those in the control group were nursed only by the holistic nursing. Then the clinical relevant indexes of the two groups were observed,and the quality of life of the patients before and after hospital discharge was assessed. Results The improvement rate,satisfaction degree,and awareness rate of health knowledge of the patients in the experiment group were 93.8%,100%and 97.4%,respectively,which were significantly higher than those of the control group(all P<0.05). The mortality rate and the complication rate of the patients in the experimental group were 0 and 2.7%,respectively,which were significantly lower than those of the control group(both P<0.05). In addi?tion,the average hospitalization days and the hospitalization cost of the experiment group were(12.2 ± 0.7)d and(4 725.0 ± 310.1)Yuan respectively,which were less than those of the control group(both P<0.01). When 6 months after the discharge from hospital,the quality of life of the patients in the experimental group in various fields was significantly better than that of the control group(all P<0.05). Conclusions The clinical nursing pathway integrated with holistic nursing can effectively improve the improvement rate and decrease the mortality of the advanced schistosomiasis patients with ascites;meanwhile,it can short?en the hospitalization time and save the hospitalization cost. Therefore,this nursing model is suitable for popularization and ap?plication in the treatment and nursing work of the advanced schistosomiasis assistance.

Objective To understand the key risk factors of schistosomiasis transmission in Jingzhou City,so as to provide the evidence for improving the treatment of these risk factors. Methods Each village of six counties was investigated and 3 envi-ronments were surveyed each village for the distribution of Oncomelania snails and animal stools in the field. The results were ana-lyzed and the risk factors of schistosomiasis transmission were assessed. Results The density of living snails was 0.43 snails per 0.1 m2,the frequency of the frames with snails was 9.12%,and no schistosome infected snails were found. All of the animal stools collected from the field were from bovines. The schistosome positive rate of animal stools was 37.50%(3/8)among the environ-ments,and the schistosome infection rate of stools was 8.11%(3/37). The schistosome infection rate of animal stools was 0 near the residence living sites,and the positive rates were 12.50%and 8.33%in the ditches and slopes,respectively(χ2=0.07,P>0.05). Conclusions Bovine is still the main infectious source of schistosomiasis,i.e. the main risk factor of the disease transmis-sion. Therefore,the strategy of controlling bovine should be strengthened.

A survey on schistosomiasis conducted in sampled 453 out of 1971 villages in Jingzhou City in the year of 2006. Miracidia hatching test demonstrated that the prevalence in human population was 3.9% (12 006/310 232), with sporadic cases of acute schistosomiasis, and the prevalence in cattle was 10.2%(270/2 651). The mean density of living snails was 0.67/0.11 m2(1 988/1 054 597) with a density of infected snails of 0.001 9/0.11 m2(1 988/713 486). In comparison to those of 2004, prevalence in humans decreased by 40.0%, prevalence in cattle increased by 22.3%; the snail-ridden area increased by 4.0%, but the mean density of living snails increased by 68.5% and the infected snail density increased by 18.8% with a decrease of 36.4% in snail infection rate. Consequently, there is an urgent need in controlling schistosome infection in cattle.

Objective To develop a Jingcen DY?1 type spraying tanker for Oncomelania hupensis snail control and evaluate its effect of field application as well as the cost. Methods The currently available tractor was used as a vector,and the mechan?ical and electrical equipments and containers were integrated with shafts,pipelines and electric lines to produce a spraying tank?er for snail control,with the functions of carrying people and molluscicides,generating electric power and getting water,mixing stocking solutions,adjusting molluscicide solutions evenly,and spraying drugs. The volume of the molluscicide solution,flow rate of water injection,and the flow rate,range and advance speed of the spray gun were tested,and the solution concentrations of molluscicide in the tanker and at the muzzle of the spray gun at different time were detected. Meanwhile,the molluscicidal ef?fect and cost of the spraying tanker were analyzed by the field test. Results The volume of the liquid storage pot of the Jingcen DY?1 type spraying tanker was 1 800 L,the flow rate of water injection was 400 L/min,the flow rate and the spray range of the standard spray gun were 110-200 L/min and 19.70-23.50 m,respectively,the efficiency of drug spraying of the spraying tanker was 6 000 m2/h,and the ratio of spray width(m)to march speed(m/min)was 1∶200. When 5 min post mother liquid recirculat?ing ,the average concentration of the molluscicide at the upper? ,middle? and lower?layers of the liquid storage pot was (1 030.39 ± 43.00)mg/L,with a variation coefficient of 4.17%. The average concentration of the molluscicide in the spraying process(spraying for 2,4,6,8,9 min)was(953.00 ± 68.87)mg/L,with a variation coefficient of 7.22%. The concentration of the residual drug in the liquid storage pot post spraying was 1 000.43 mg/L,which reached the effect concentration for snail con?trol. After spraying for 7 days in the field,the average density of living snails reduced by 88.20% as compared to that before spraying,and the adjusted mortality of snails was 87.65%. The unit cost of Jingcen DY?1 spraying tanker was 0.086 7 Yuan/m2, which reduced by 58.20% as compared to that of the conventional spraying tanker. Conclusions Jingcen DY?1 type spraying tanker for snail control which integrates various equipments together can effectively control the concentration and dose of the mol?luscicide,and the machine is labor?saving,efficient,economic and well adapted,and is worthy to be widely applied.
