Objective To assess the treatment of splenic artery aneurysms (SAA) and prognosis.Methods Clinical data of 18 SAA patients treated in our hospital from 1999 to 2011 were retrospectively analyzed. Results There were 18 patients diagnosed as SAA,including 7 males and 11 females.The average age was 53.8 ± 7.3 years.8 patients were asymptomatic found by routine physical examination,7 patients complained upper left abdominal pain,3 cases suffered from aneurysm rupture. Diagnosis was established by three-dimensional computed tomography angiography (3DCTA) in 14,Digital subtraction angiography (DSA) in 3 and magnetic resonance angiography (MRA) in 1 patient.Three patients with ruptured splenic artery aneurysm underwent emergent operations,11 patients underwent elective surgery or interventional therapy.Surgical procedures included aneurysmectomy and splenectomy in 4 patients,distal pancreatectomy in 5 cases; aneurysmectomy and splenic artery ligation in one patient; and aneurysmectomy with splenectomy and colon resection in 1 case.Interventional embolization by coils of the splenic aneurysm in 3 patients.The remaining 4 being asymptomatic and with tumor diameter less than 2 cm were put on a close follow-up.There was no perioperative mortality.Two were lost to follow-up.16 cases were followed-up for averaging 3.2 years. 1 patient died of cerebral hemorrhage after four years. Conclusions Splenic artery aneurysms was a rare disease and with usually occult symptoms,but rupture can leads to abdominal apoplexy.Open surgery and minimally invasive endovascular treatment is effective and offers a good prognosis.

BACKGROUND:At present, spinal cord ischemia/reperfusion injury is considered as the main reason for secondary paralysis after spinal decompression, and to control the levels of stress-related proteins and excitatory amino acids plays an important role in the treatment of spinal cord ischemia/reperfusion injury. OBJECTIVE:To investigate the expression level of protein disulfide-isomerase A3 (PDIA3) after spinal cord ischemia/reperfusion injury in rabbits. METHODS:Thirty-six New Zealand white rabbits were enrolled, the models of spinal cord ischemia/reperfusion injury were established using Zivin's method, and were then randomized into six groups (n=6 per group). The rabbit abdominal aorta in control group was exposed without vascular occlusion and then the abdominal cavity was closed 30 minutes later. In experimental groups, the abdominal aorta was blocked for 30 minutes, followed by 0, 6, 12, 24 and 48 hours of reperfusion, and then the abdominal cavity was closed. The neurological function was evaluated with a modified Tarlov score. The L3-5lumbar vertebrae were removed, and PDIA3 was screened by two-dimensional fluorescence differential gel electrophoresis combined with mass spectrometry, and then its temporal and spatial changes in the spinal cord were detected by western blot assay and immunohistochemistry. RESULTS AND CONCLUSION:The function of hind limbs was improved in all the experimental groups after spinal cord ischemia/reperfusion injury, and the modified Tarlov scores reached the peak at 24 hours after schemia/reperfusion injury, and decreased slightly at 48 hours. The expression of PDIA3 in the control group showed clear imprinting, which was slightly strengthened at 0 hour, became more strengthened at 6-12 hours, significantly reduced to the minimum level at 24 hours, and returned to the level of 6-12 hours at 48 hours after ischemia/reperfusion. Immunohistochemical results showed that there was visible PDIA3 in the cytoplasm of neurons, and the expression level in the interneurons was significantly higher than that in the motor neurons. These results suggest that upregulated PDIA3 appears in the development and progression of spinal cord ischemia/reperfusion injury, indicating that PDIA3 is closely related to spinal cord ischemia/reperfusion injury, which can be used as a new diagnosis and treatment target.

The process flow and the main devices of a new two-stage dry-fed coal gasification pilot plant with a throughout of 36 t/d are introduced in this paper. For comparison with the traditional one-stage gasifiers, the influences of the coal feed ratio between two stages on the performance of the gasifier are detailedly studied by a series of experiments. The results reveal that the two-stage gasification decreases the temperature of the syngas at the outlet of the gasifier, simplifies the gasification process, and reduces the size of the syngas cooler. Moreover, the cold gas efficiency of the gasifier can be improved by using the two-stage gasification. In our experiments, the efficiency is about 3%-6% higher than the existing one-stage gasifiers.

OBJECTIVE:To compare the quality control index between Jinzhen Suanzao teabag and decoction,and explore the alternative supplement of teabag to decoction. METHODS:The test sample solutions of Jinzhen Suanzao teabag and decoction were prepared by hot-maceration method and water-decoction method. The contents of water soluble extract and total flavonoids were de-termined and compared between 2 kinds of preparation. The leaching rates of teabag were investigated at different soak time(0,5, 10,15,20,25,30 min) to optimize soaking time. RESULTS:The average content of water soluble extract were 50.56% and 44.45%(P<0.05) respectively for the teabag and decoction. The total flavonoids content were 0.64 mg/g and 0.69 mg/g (P<0.05). The dissolution amount of teabag were increasing and leaching rate increased within first 20 min,and reached balance gradu-ally 25 min later. CONCLUSIONS:According to the convenience of use and results of each index,the difference in quality control index is not great between 2 kinds of preparation. Teabag can be as the supplement of decoction.
