The records of 10 consecutive cases that sustaining traumatic CCF were retrospectively reviewed.The age of cases ranged from 18 to 55 years old, and all of them were complicated with fracture of orbit and base of skull.The causes of injuries, the characteristics of ocular manifestations,the findings in CT or cerebral angiography, and methods of treatment of CCF were analysed. The results showed that 9 cases were cured by operation (90%). The cavernous sinus fistulae were closed. The ocular signs such as exophthalmos, vascular murmur in eyelid and conjunctival swelling disappeared.One case had remaining exophthalmos.Nine patients who were cured were followed up for 6 months to 10 years.No ocular signs recurred in all cases. In 2 cases there were mild complications.It suggested that the pulsating exophthalmos,vessel murmur in eyelid and marked conjunctival vessel dilatation were the characteristics of ocular manifestations in CCF. Endovascular embolization with detachable balloon or spring coil is currently the treatment of choice and it is efficacious and safe in traumatic CCF.

Objective To evaluation the anatomy relationship between thoracic artery and coronary artery by using 256 layer spiral CT angiography. Methods The angiographic images of thoracic aortic and coronary artery angiography were re?vealed in 200 patients with chest pain. Values of the major branch length, diameter, length of the aorta-coronary artery by?pass on both sides of the thoracic artery and coronary artery were measured. Results The diameter of thoracic artery was (2.52±0.38) mm, and the length of thoracic artery from the starting point to terminal was (190.12 ±1.90) mm. There were no significant differences in the thoracic artery lumen diameter and length between both sides. The inner diameters of left anteri?or descending coronary artery, left circumflex, diagonal branch, right coronary artery and the posterior interventricular branch were (2.82 ±0.25), (2.60±0.12), (2.22±0.25), (3.02±0.27) and (2.35±0.35) mm respectively. There were no significant differences in thoracic artery diameters except for the right coronary artery diameter, which was higher than that of the thorac?ic artery. About free transplantation the length from 2cm above in the ascending aorta starting to the halfway point of anterior descending coronary artery, to the atrioventricular node along the left circumflex way, to the atrioventricular node along the right coronary artery and from the atrioventricular node to halfway point of posterior interventricular branch was shorter than that of thoracic artery (P<0.05). About situ transplantation in addition to the length from the thoracic artery start department to the point of anterior descending compared with the thoracic artery length, there were no statistical significance ( P>0.05). The length from the thoracic artery start department to the left-hand atrioventricular node, to the right coronary artery atrio?ventricular node was higher than that of the thoracic artery length (P<0.05). Conclusion The branches of internal thoracic artery and coronary artery are similar. About situ transplantation is suitable for the wall blood vessels before the heart. With free thoracic artery transplantation, its length can meet any bridging from the ascending aorta to the coronary arteries.

Objective To study the value of 256-slice spiral CT (MSCT) in internal thoracic artery. Methods The angiographic images of 107 patients who were suspected thoracic and abdominal aortic diseases were retrospectively ana-lyzed. The running rule and branches of internal thoracic artery on both sides were observed. Each side of the internal thorac-ic artery was divided into 3 sections according to the running rule. The lumen diameter, vessel length and its branches were measured in three segmental vascular of the internal thoracic artery. The lumen diameter of the diaphragmatic artery diame-ter,and the distance between internal thoracic artery and each border of the sternum were also measured. Results Both sides of the internal thoracic and diaphragmatic arteries were shown in 107 patients (100%). There were significant differenc-es in vascular lumen diameter of intrathoracic artery of both sides (P＜0.05). There were no significant differences between both sides of the corresponding segments (P>0.05). The left internal thoracic artery was significantly longer in the left side than that of right side (P＜0.05). There were no significant differences between the diameter of diaphragmatic arteries and the distance between the internal thoracic artery and the sternal edge of two sides (P>0.05). Conclusion The application of 256-slice spiral CT angiography can clearly show the running rule and anatomical features of internal thoracic artery ,and provide a relatively important clinical information.

Objective To analyze the common causes leading to lung infection following renal transplantation and provide targeted preventive measures to reduce the incidence of lung infection.Methods The clinical data of 561 recipients who underwent renal transplantation from January 2006 to February 2011 were retrospectively analyzed.The recipients were divided into two groups:group Ⅰ,from January 2006 to December 2009 (n =416) ; group Ⅱ,from January 2010 to February 2011 (n =145).The causes possibly leading to lung infection which took place 3 days before the appearance of the clinical symptoms were offered by the patients who suffered lung infection of group Ⅰ.And then the causes were summarized and analyzed to formulate the specific and comprehensive measures to prevent the infection.Finally the measures were applied to recipients in group Ⅱ from January 2010.After applying the measures for 14 months,the incidence of lung infection in group Ⅱ was counted and compared with that in group Ⅰ to see the preventive effect.Results There were 58 cases of lung infection in group Ⅰ (58/416,13.9％) and 12 cases in group Ⅱ (12/145,8.3％). There was significant difference in the incidence of lung infection between two groups (x2 =4.0361,P＜0.05).All of the recipients with lung infection were hospitalized in six months after the transplantation.The causes leading to lung infection of 58 cases in group Ⅰ were as follows:6 cases due to being excessively tired,3 cases due to guest visiting,12 cases due to abrupt change of weather,9 cases due to exposure to public place,8 cases due to returning to hospital,6 cases due to close contact with children,5 cases due to close contact with animals,and the other 9 cases without specific causes found.Conclusion The incidence of lung infection following renal transplantation can be notably reduced by the application of targeted and concrete health propaganda education and preventive measures based on analysis on the specific causes of infection.

Objective To determine the conversion equation for X(copies/ml, lg) quantity values of domestic HCV RNA quantitative fluorescence amplification assays approved by SFDA and Y( IU/ml, lg)reference values of standard substance. Methods The second generation WHO International Standard (NIBSC code:96/798) was mixed with human AB blood type serum to create 7 different dilutions which included 100 000, 50 000, 25 000, 10 000, 5 000, 2 500 and 1 000 IU/ml. Two different batches of each three domestic hepatitis C virus RNA real-time fluorescence quantitative PCR assays and 2 different batches of each assay were employed to detect the 7 different concentration samples with real-time PCR. Each test was performed 4 times repeatedly. Results The correlations between X( copies/ml,lg) values of domestic HCV RNA assays and Y(IU/ml,lg) reference values of standard substance were as follow,Assay A:Y =0. 902 0 X+0.284 9,R2 =0.953 3,P＜0. 01,n =56;Assay B: Y=0. 875 7 X +0.562 4,R2 =0.956 5,P＜0.01,n =56; Assay C: Y = 0. 843 8 X + 0. 560 5, R2 = 0. 945 8, P ＜ 0. 01, n = 56. Conclusions All the conversion equations are different among the quantity value of three assays and the reference values of standard substance, that suggests it is necessary to perform more stringent traceability analysis for the quantity values of 3 assays. Through standardizing the quantity values preliminarily, the conversion equation can enhance the comparability between the quantity values of different assays, and provide a standard of HCV RNA virus load detection for clinical diagnosis and treatment monitoring of HCV infection.

Objective:To screen the ectodysplasin A (EDA)gene mutation in the patients with non-syndromic tooth agenesis and ectodermal dysplasia,and to analyze the phenotype of missing teeth pattern in these two groups of patients.Methods:In the study,174 patients with tooth agenesis (143:non-syn-dromic,31:ectodermal dysplasia)and 451 health control volunteers were enrolled from the clinic,and the genome DNA was extracted from either peripheral blood or oral mucosal swab.The coding region of EDA gene was then amplified by PCR,sequenced and blasted to online NCBI database.The missing teeth were recorded for all patients,and the missing teeth from patients with EDA mutation were com-pared among the different dentition sites.Results:33 patients were identified with EDA mutation.In the non-syndromic patients,13 /143(9.09%)were identified with EDA mutation,while in patients with ec-todermal dysplasia,20 /31 (64.52%)were found with EDA mutation.Ten novel EDA mutations were identified (c.769G >C[p.G257R],c.936C >G[p.I312M],c.223G >A[p.E75K],c.1166C >T[p. P389L],c.133G >C[p.G45R],c.1109G >A[p.E370K],c.914G >T[p.S305I],c.916C >T[p. Q306X],c.602G >T[p.G201V],c.88 -89insG[p.A30GfsX69]).For each dentition site there was no statistic difference in the number of missing teeth between the left and right sides,so the number from both sides were combined later in the analysis.In the patients with EDA mutation,the non-syndromic pa-tients had fewer missing teeth (15.9 ±6.4 missing teeth for each,207 /364 in total)than the patients with ectodermal dysplasia (23.9 ±4.3,478 /560).In the non-syndromic patients with EDA mutation, the maxillay central incisors and first molars were less affected,with the same missing rate as 19.2% (5 /26).While the mandibular central incisors (with a missing rate of 76.9%,20 /26),the maxillary late-ral incisors (the missing rate:88.5%,23 /26 ),the mandibular lateral incisors (the missing rate:80.8%,21 /26),and the maxillary first premolars (the missing rate:80.8%,21 /26)were more likely to be missing.In the ectodermal dysplasia patients with EDA mutation,only maxillary central incisors (the missing rate:60%,24 /40),maxillary canines (the missing rate:70%,28 /40),mandibular ca-nines (the missing rate:67.5%,27 /40),maxillary first molars (the missing rate:65%,26 /40)and mandibular first molars (the missing rate:72.5%,29 /40)had higher possibility of persistence.Teeth at other dentition sites were more likely to be affected (the minimum missing rate:87.5%,35 /40). Conclusion:The findings would help to reveal the EDA gene and its function in ectodermal organogene-sis.
