Objective: To investigate the effective of Sanhua decotion(三化汤) on early brain water content,penetration of blood brain-barrier and the expression of aquaporin4(AQP4) in rats with acute cerebral ischemia/reperfusion(I/R).Methods: The string inserting method was employed to reproduce the rat model of focal cerebral I/R SD rats were randomly divided into sham operation group,model group and Sanhua decotion group.After I/R,each group was then divided into 6 hours,12 hours,24 hours,48 hours and 72 hours five subgroups.The brain water content was detected by the ratio of wet/dry weight to evaluate cerebral edema and the blood-brain barrier(BBB) damage was observed by Evan′s blue(EB) staining.The AQP4 mRNA and protein expressions were measured by reverse transcription-polymerase chain reaction(RTPCR) and immunohistochemistry respectively.Results: Compared with sham operation group,the brain water content,EB content,AQP4 protein and AQP4 mRNA expressions were increased at every time point after I/R in the model group(P

Objective To analyze the effect of salvia tetramethylpyrazine on hemorheology in patients with vertebrobasilar transient ischemia attack (VB-TIA). Methods 84 patients with VB-TIA were divided into observation group and control group, 42 cases in each group. They both received the treatment of Ginkgo-diyidamolum injection. The observation group were treated by salvia tetramethylpyrazine, and the control group were treated by compound Danshen injection. The therapeutic effect of the two groups and the changes of blood rheology were compared. Results The clinical remission rate of the observation group was significantly higher than that of the control group, and the time of onset and symptoms of the drug were shorter than those of the control group (P < 0.05). The blood flow velocity of vertebral basilar artery in the two groups were significantly higher than those in the observation group (P < 0.05). After treatment, the hemorheology of the two groups were significantly improved, the high shear viscosity and low shear viscosity, platelet aggregation rate, erythrocyte deformation index, erythrocyte aggregation index and blood haematocrit of observation group improved more obviously (P < 0.05). The incidence of adverse reactions in the two groups was not statistically significant. Conclusion Salvia tetramethylpyrazine could effectively shorten the drug onset time, improve the blood velocity of vertebrobasilar artery, recover blood rheology and stability on the condition of not increasing the adverse reactions, which has a positive effect on the clinical remission rate.

Hemangioma of the penile head is rare. This paper reported a patient, 16 years old, who was admitted to hospital due to the discovery of multiple masses on the head of the penis for more than two years. Physical examination showed that three vascular mass-like masses were distributed along the coronal sulcus at the 3, 9, and 12 points of the penile head, and the larger one was about 10 mm×5 mm size, blue-purple, soft, and painless. Ultrasound examination suggested that the patient had a penile head hemangioma. Surgical resection was performed, and the postoperative pathological diagnosis was penile head hemangioma.The follow-up of 3 months showed that the wound healed well without recurrence, and the penile head appearance was not obviously deform.
