Objective To determine the efficacy of coronary artery bypass grafting (CABG) in children with coronary obstructive disease subsequent to Kawasaki disease. Methods Between Feb 2005 and Sep 2009, 6 children with ischemic heart disease due to Kawasaki disease comprised the study group. The age of patients at operation was ranged from 6 to 12 years with a mean of ( 8.0 ± 2.3 ) years. The preoperative EF was ranged from 0.33 to 0.71 with a mean of 0.57 ± 0.15. There was one case with moderate mitral valve regurgitation. Results All patients survived the procedures. The mean number of bypass graft was 2.0 ±0.6,with 4 internal thoracic arteries and 7 radial arteries. Mitral valve repair was employed in 1 case. The cardisc function ( NYHA and EF) was significantly improved postoperatively. Postoperative CTA showed no graft disease in all cases. Conclusion CABG using the arterial grafts can provide attractive mid-term results in patients with obstructive coronary arteries associated with Kawasaki disease.

Objective:To investigate the relationship of expression of vascular endothelial growth factor (VEGF) and clinical features in patients with intracranial aneurysm and arteriovenous malformation (AVM).Methods:A total of 64 patients with AVM and intracranial aneurysm,who were treated in First Hospital of Shijiazhuang from February 2011 to November 2015,were chosen as research subjects,AVM were 32 cases and intracranial aneurysm were 32 cases.The samples were sectioned for VEGF immunohistochemical staining;the location and intensity of staining were recorded;the positive indexes were computed.The VEGF expression of different age and Hunt&Hess classification in patients with intracranial aneurysms were analysed;the VEGF expression of different diameters,ages,Spetzler classification in patients with AVM were analysed.Results:There were no statistical differences in the VEGF expression of different ages in patients with intracranial aneurysms (P＞0.05);the VEGF expression of different Hunt&Hess classification in patients with intracranial aneurysms was statistical difference (P＜0.05).The positive rate of VEGF in the artery of AVM was lower than that in the vein,the difference was statistically significant (P＜0.05).There were no statistical differences in the VEGF expression of the different Spetzler classification,different diameters and different ages in patients with AVM (P＞0.05).Conclusion:The expression of VEGF in the vein and the artery of patients with AVM is different,the expression of VEGF is not correlated with the age of intracranial aneurysm and the size and age of AVM.VEGF cannot be used as a predictor in the patients with intracranial aneurysms and AVM.

0.05).However,the level of PRG-1 protein in cerebral cortex of experimental group was significantly higher than that of control group at 7 d(t=2.347,P=0.041).Conclusion The up-regulated expression of PRG-1 in cerebral cortex may be associated with the recurrent neonatal seizure-induced brain damage.

Objective To observe the feasibility, safety and efficacy of percutaneous coronary intervention (PCI) for treatment of chronic total occlusions (CTO)by only the guidewire versus by the guidewire dependent on balloon. Methods The 108 patients with CTO confirmed by coronary angiography and treated with PCI from March 2009 to March 2011 were enrolled in this study, including 59 cases with old myocardial infarction, 22 unstable angina cases and 27 stable angina cases. The clinical data, outcomes of PCI, perioperative complications and incidence of major adverse cardiac events (MACEs) during follow-up were retrospectively analyzed between group A (only by the guide wire) and group B (by guide wire dependent on balloon). Results The 88 of 108 patients (81.5%) got successful operations. The success rate of CTO was a little higher in group B than in group A [80.0%(52/65) vs. 83.7%(36/43), P＞0.05]. The rate of total complications was more in group A than in group B [10.8%(7/65) vs. 2.3%(1/43), P＜0.05]. No death occurred during operation, no MACE occurred after operation in hospital and no patients underwent emergency coronary artery bypass graft (CABG) in the two groups. Conclusions The PCI for treatment of CTO used by the guidewire dependent on balloon shows a safety and effecary.

Objective To investigate the correlation between subacromial space and acromial shoulder impingement syndrome (SIS).Methods The clinical and imaging data of 40 patients with SIS were collected and retrospectively reviewed.The shape of acromion and tears of rotator cuff of all patients were classified.A cromion-Humerus (A-H) distance was measured.Results Among 40 patients,there were 9 cases of type Ⅰ,12 cases of type Ⅱ,19 cases of type Ⅲ.32 patients had subacromial space narrowing.7 cases had calcification in the supraspinatus tendon and 10 patients had acromioclavicular joint ostcoarthritis.There were 17 cases of type Ⅰ,15 cases of type Ⅱ,18 cases of type Ⅲ of tears of rotator cuff.6 patients had subacromial bursa thickening,5 patients had subacromial-deltoid sac fluid and 10 patients had the joint capsule fluid.2 patients had jointlabrum avulsion,3 patients had the supraspinatus muscle atrophy and 4 patients had Bankart Lesion.There was no significant difference was found in A-H distance measured with X-ray and MRI(P =0.137 0).There was positive correlation between the A-H distance and class of rotator cuff(r =0.545,P =0.000 1).Conclusion There exists some correlation between subacromial space and SIS.The diagnosis and class of SIS can be assessed according to narrowing range of subacromial space.

Objective:To analyze the levels of individual doses to radiation workers receiving medical radiation exposure in hospitals in Jiangxi province, so as to provide reference for radiation protection.Methods:The radiation workers of different types in medical institutions in Jiangxi were investigated from 2014 to 2018, involving diagnostic radiology, radiotherapy, nuclear medicine and interventional radiology. Statistical analyses were made of the individual doses to medical radiation workers in the province.Results:The total number of monitored workers were 23 833 with average annual individual effective dose of 0.316 mSv. NR1 and NR5, the ratios of the number of workers receiving annual individual doses exceeding 1 and 5 mSv to the total monitored workers were 4.32% and 0.10%, respectively. During the five-year period, the average annual individual effective dose showed a upward and then downward trend, with peak appearing in 2017. A total of 17 909 diagnostic radiologists were monitored, accounting for 75.14% of the total number of monitored workers. The average annual individual effective dose received by workers was 0.329 mSv, the highest, in interventional radiology, followed by diagnostic radiology 0.318 mSv, nuclear medicine 0.283 mSv, and radiotherapy 0.269 mSv, respectively. There were statistically significant differences among radiation workers of different types ( χ2=489.39, P<0.001). Conclusions:The average annual individual effective dose to the radiation workers in medical institutions in Jiangxi province meets the relevant national standards, but with an upward trend in nuclear medicine. The higher levels of individual doses to radiation workers are seen in primary and secondary hospitals. It should be strengthen the oversight of radiation workers in nuclear medicine and in primary and secondary hospitals.

Objective To explore the epidemical pattern of acute schistosomiasis in Poyang Lake area so as to provide the scientific evidence for control-strategy-making. Methods The data of acute schistosomiasis in 12 counties along Poyang Lake from 1960 to 2007, including the data of 2 special investigations from 1982 to 1984 and from 1987 to 1989 were collected and analyzed with the retrospective investigation methods. Results There were 29 864 cases of acute schistosomiasis in 12 counties of Poyang Lake area from 1960 to 2007, accounting for 85.5% of the total acute schistosomiasis cases of Jiangxi Province. The largest number of cases existed in Yugan County, accounting for 18. 7%. The peak of acute schistosomiasis prevalence was in 1987 with 2 088 cases. However, the case of acute schistosomiasis declined significantly, keeping at a low level, since 1990. During the 2 special investigations, the people whose age were lower than 30 years old, were the susceptible populations of acute schistosomiasis (86. 1% and 82. 9% , respectively) , most of them were peasants and students, and the infection rates were 57. 4% and 21.2%, 61.7% and 21. 8%, respectively. Fishing and swimming were the main infection ways, with the infection rates of 43.0% and 44.9% , respectively. The peak season of infection was from April to October. Conclusions The river bank and continent of Poyang Lake are the main infection areas, the spring and autumn are the main epidemic seasons and the susceptible populations are the peasants, fishmen and young students. It is very important to enhance the comprehensive prevention and treatment measures in the key areas and population for schistosomiasis control.
