Objective　To analyze the clinicopathological features of angiolymphoid hyperplasia with eosinophilia (ALHE). Methods　The pathological specimens of 7 cases of ALHE collected in our department from 1950 to 1999 were sectioned, stained and observed. Results　There were 3 pathological characteristics in ALHE: ①massive hyperplasia of capillaries in the dermis; ②the endothelial cells proliferated and swelled, projecting into vascular cavity like tombstones; ③mixed infiltration of lymphocytes and eosinocytes in the vessels. Conclusion　ALHE is a disease with local benign proliferated vessels, whose etiology and pathogenesis is still unknown. It is necessary to grasp the pathological changes of ALHE to distinguish it from other diseases.

OBJECTIVE To assess the efficancy of Yangxue Qingnao granules on simvastatin-induced vascular injury model in zebrafish. METHODS Since statins can inhibit vascular development in zebrafish,in this study,we developed a novel animal model using 1 to 3 day post-fertilization larval zebrafish by optimizing the doses and duration of simvastatin exposure.Five pro-angiogenic drugs with a variety of mechanisms were tested to validate the newly developed zebrafish model. Zebrafish was treated with different concentration of Yangxue Qingnao granules( 62.5,125 and 250 μg·mL-1)for 2 d then tested for the area of subintestinal vein vessels. RESULTS Vascular regeneration promoting effect of five pro-angiogenic drugs (calycosin, astragaloside, chlorogenic acid, ferulic acid and Panax Notoginseng Saponins)were 8-48%,24-51%,35-58%,28-75% and 37-69%,respectively.In 62.5,125 and 250 μg·mL-1Yangxue Qingnao granules group,vascular regeneration promoting effect were 21% (P>0.05), 84%(P<0.01) and 53%(P<0.01). CONCLUSION Our results demonstrate that the zebrafish vascular injury model validated in this study could be used for in vivo angiogenesis studies and drug screening and for assessing pro-angiogenic drugs with different mechanisms.Yangxue Qingnao granules could promote the vascular regeneration in zebrafish.

Cerebral ischemia is due to cerebral blood supply disorders caused by ischemia and hypoxia resulting in localized ischemic brain necrosis or brain softening of the disease, leading to irreversible brain damage and subsequent loss of neuronal function is a serious threat to human health One of several diseases. For patients with cerebral ischemia, often the lack of effective and extensive treatment. In addition, cerebral ischemia with morbidity, morbidity and mortality are characterized by high, so by the medical profession at home and abroad attention. As a traditional Chinese medicine, cordyceps sinensis (CS) is a complex of ergot fungus, which is parasitized on the larvae of the bat-moth family. The compound is composed of cordycepin, cordyceps polysaccharide, cordyceps sinensis peptides, ergosterol, mannitol, fatty acids and trace elements such as a variety of ingredients, with a wide range of pharmacological effects. Over the years, domestic and foreign scholars on the pharmacological effects of cordyceps sinensis were more comprehensive study of its prevention and treatment of cerebral ischemia is also deepening, found that cordyceps sinensis on cerebral ischemia with anti-inflammatory, reduce oxidative damage and neuronal ischemia damage, reduce neuronal apoptosis, improve memory cognition, reduce thrombosis, inhibit NO production, enhance mitochondrial energy supply, scavenging free radicals and other prevention and treatment. But no relevant review. In this paper, the domestic and foreign literatures on the prevention and treatment of cerebral ischemia by cordyceps sinensis were summarized, analyzed and summarized in order to provide useful information for the research and further development of cordyceps sinensis.

Objective To analyse the diagnosis and treatment of testicular torsion. Methods The clinical data of 66 cases of testicular torsion were retrospectively analysed. Results Among the 66 cases,32(48.5%) paid the first medical visit within 10 h,and 24(36.4%)were confirmed diagnosis at the first visit.False negative results occurred with color Doppler flow imaging(CDFI),and 8 testicles were damaged due to the false negative diagnosis.Thirty-three patients without prophylactic contralateral orchidopexy were followed up for 6 months to 20 years,and one experienced recurrent torsion. Conclusion The testicular torsion must be considered when a sudden acute scrotum pain is occurred.Testicular damage is closely related to the torsion time,and delayed medical intervention contributes to the testicular damage.Highly suspected cases should be performed surgical exploration timely due to the false negative results with CDFI.Prophylactic contralateral orchidopexy is recommended.

OBJECTIVETo study the protective effect of dl-tetrahydropalmatine(dl-THP) on liver injury induced by carbon tetrachloride (CC4) in mice.

METHODMice were administracted with dl-tetrahydropalmatine ip 20, 40 mg x kg(-1) daily for 9 d respectively, and then actue liver injury model was induced by 0.1% carbon tetrachloride ip 20 mL x kg(-1). The mice were killed 17 h after injection ip of CCl4, serum alanine and aspartate aminotransferase (ALT and AST) activity were measured, and maleic dialdehyde (MDA) and superoxide dismutase(SOD) activity in liver were detected.

RESULTdl-THP significantly reduced the level of serum ALT and AST, inhibited lipoperxidation in liver, while increased SOD activity in liver tissue. Degeneration of hepatocytes was obviously prevented in mice treated with dl-THP, and the liver histological structure was well maintained.

CONCLUSIONdl-THP has inhibitory effects on liver injury induced by CCl4 in mice. The mechanisms may be related with its effects of reducing lipid peroxidation product.
