Objective To summarize the clinical experience of nasal endoscopic treatment for refractory epistaxis. Methods .A retrospective analysis was made on 258 patients with refractory epistaxis treated with intranasal endoscopic exploration and hemostatic treatment from January 1998 to December 2004 in this hospital. Results .Hemorrhage was found on the nasal septum and the lateral nasal wall in 118 and 47 patients, respectively. Nose bleeding resulted from intranasal tumor in 8 patients. The site of bleeding was not clearly identified in 85 patients. Of the 258 patients, 257 responded to the treatment (99.6%) and 1 died ( 0.4%).Recurrent bleeding occurred in 43 patients. The incidence of recurrent bleeding was significantly higher in patients with unknown bleeding sites than in clearly diagnosed patients (?2=17.689,P=0.000). Conclusions .The emphasis of nasal endoscopic treatment for refractory epistaxis should be laid on the initial management, during which the bleeding site should be carefully identified. For patients with repeated nose bleeding, a combination treatment, including endoscopic filling-up of the anterior nasal cavity, endoscopic embolization of anterior and posterior nose, or embolization of the internal maxillary artery, is necessary.

ObjectiveTo observe the effect ofTong Du acupuncture-moxibustion, conventional acupuncture, and medication on the bone marrow stem cells (BMSCs) mobilization markers CD34+and CD133+, neurological deficit score in patients with ischemic stroke.Method Totally 120 eligible subjects with ischemic stroke were randomized into aTong Du acupuncture-moxibustion group (group A), a conventional acupuncture group (group B), and a medication group (group C), 40 in each group. In addition to the conventional medication given to all three groups, patients in group A also received moxibustion at Baihui (GV20), bloodletting at Dazhui (GV14), and acupuncture at Fengchi (GB20), Quchi (LI11), Hegu (LI4), Zusanli (ST36), and Sanyinjiao (SP6); patients in group B also received acupuncture at Fengchi, Quchi, Hegu, Zusanli, and Sanyinjiao; group C received patent Chinese medicine Tong Xin Luo capsules. The intervention lasted 14 d in all three groups. The CD34+and CD133+and neurological deficit score were evaluated and compared before and after intervention.Result The three treatment methods all significantly increased the level of CD34 + and CD133+in peripheral blood (P<0.05,P<0.01); the intergroup comparisons showed significant differences among the three groups (P<0.05), and the level in group A was significantly different from that in group B and C (P<0.05), while there was no significant difference between group B and C (P>0.05); the three treatment methods all improved the neurological deficit score to various extent, and the result in group A was significantly different from that in group B and C (P<0.05,P<0.01), and there was also a significant difference between group B and C (P<0.05).ConclusionsTong Du acupuncture-moxibustion, conventional acupuncture, and medication can influence the BMSCs and neurological deficit to different extent; the effect ofTong Du acupuncture-moxibustion on the BMSCs and neurological deficit is more significant than that of the conventional acupuncture and medication, suggesting thatTong Du acupuncture-moxibustion method should have advantage in treating cerebral infarction.
