ObjectiveTo investigate the knowledge of stroke in patients with first stroke. Methods259 patients with first stroke were investigated with questionnaire. ResultsMost patients knew that hypertension was a risk factor of stroke, early treatment of stroke was important and hemiplegia was the frequent early symptom of stroke. They lacked other knowledge of stroke such as other risk factors, standards of hypertension, and so on. ConclusionIt is important to improve the knowledge of stroke in patients.

Objective To explore the role and significance of standardized scheme for diagnosis and treatment of pulmonary thromboembolism(PTE).Methods The clinical data of 163 consecutive PTE patients who were treated in our hospital from Jan.1972 to Dec.2006 were retrospectively reviewed.The patients were divided into group A and group B based on the time of application of standardized treatment and diagnosis for PTE.The clinical data of the two groups were analyzed and compared.Results The main risk factors included deep vein thrombus,operation,injury,fracture and tumors,etc.Dyspnea was the most important clinical symptoms.The incidences of dyspnea in group A and B were 92.5% and 84.6%,respectively.The diagnostic case and the ratio of final diagnosis in group B was increased compared to those in group A on an annual basis.The median time for diagnosis was shortened(P

Objective To improve the diagnosis and treatment of eosinophilic lung disease.Methods Patients who were diagnosed with eosinophilic lung disease and hospitalized in the First Affiliated Hospital of Guangxi Medical University Hospital were retrospectively analyzed from January 2004 to August 2012.Data of etiology,clinical manifestation,imaging and pathological features,diagnosis and treatment were recorded.Results A total of 25 patients were diagnosed with eosinophilic lung disease including 9 chronic eosinophilic pneumonia,6 churg-strauss syndrome,and 10 cases of parasitic infection of which two patients were the simple pulmonary eosinophilia (L(o)ffler syndrome).Eosinophil counts in peripheral blood and bronchoalveolar lavage fluid (BALF) were increased.Arterial gas analysis showed varying degree of hypoxemia,which pulmonary function tests showed restrictive,obstructive,mixed ventilatory dysfunction.Chest CT showed bilateral flaky,streak or flake diffuse ground-glass infiltrates and reticular opacities.Results of pulmonary biopsy or skin biopsy identified diffuse eosinophil infiltration.Corticoidsteroid therapy alone or combined with immunosuppressive agents were both effective.Conclusion (1) Liver fluke and other food-borne parasites are the most common causes in eosinophilic lung disease; followed by unexplained chronic acidophilic granulocyte pneumonia; (2) In addition to histopathological evidence,the diagnosis of eosinophilic lung disease was made comprehensively based on clinical features,laboratory test,the BALF analysis,and imaging data.

Objective: To study the effects of ginger oleoresins(GO) on blood lipids in hyperlipidemic mice and the platelet aggregation in rats.Methods: The rat platelet aggregation was induced by ADP and AA in vitro, and the inhibition by GO was tested by light transmission. The animal model of hyperlipidemia was establised by feeding Kunmimg mice with high lipid feed stuff. The effects of GO on serum lipid and hepatic MAD in hyperlipidemic mice was investigated. Results: GO could effectively inhibit rat platelet aggregation induced by ADP and AA in vitro, which were 58.9%,97.5% respectively, and in dose dependant manner. Besides, GO could also significantly decrease serum TC, LDL, AS index and hepatic MDA in hyperlipidemic mice, which were 16.45%, 60.45%,37.30% and 54.27% respectively, and showed no side-effect on liver. Conclusion: Long-term consumption of GO can effectively modulate blood lipids, prevent thrombosis and AS.

ObjectiveTo compare the clinical effect of posterior circumferential fusion with versus without intertransverse process fusion on lumbar instability in aged patients. MethodsThe elderly with lumbar instability were treated with the posterior instrumented circumferential fusion technique in 80 cases. Among 58 patients followed up for at least 2 years, 28 cases (group A)underwent posterior circumferential fusion with intertransverse process, while 30 cases (group B)without intertransverse process. X-ray examination was used before and 1, 3, 6, 12 and 24 months after operation to evaluate the fusion condition of the bone graft, and visul analogue scale (VAS) and Oswestry disability index (ODI) questionnaire were applied to assess the pain of center back and leg,and the conventional activity.ResultsThe operation time and blood loss were more in group A[(185.3±56.6) min and (376.3±92.9) m1] than in group B [(146.4±46.3) min and (234.3±64.5)ml (t=12.37, 37.49, P＜0.01)]. All the 58 cases were followed for at least 2 years. The 27 cases (96.4％) of group A and 28 cases (93.3％) of group B got bone fusion (x2 =0.004, P＞0.05).There were marked differences in the VAS of center back at 1 and 3 months after operation between the 2 groups (t=3.178, 2.158, both P＜0.05), while no difference at the other 3 time point. VAS about the leg pain and the ODI showed no differences between group A and B after operation (all P＞0.05). ConclusionsFor the lumbar instability in the elderly, the posterior circumferential fusion with or without intertransverse process fusion can achieve a similar high rate of fusion and satisfactory clinical results,andtheposteriorcircumferentialfusionwithoutintertranaverseprocess is recommended for less trauma.
