BacKground:RectaI carcinoid is a rareIy seen neuroendocrine tumor. TiII now,there is controversiaI for the treatment modaIities of rectaI carcinoids with diameter between 1-2 cm. Aims:To study the expression of Ki-67 in rectaI carcinoids and the efficacy and safety of endoscopic resection. Methods:A totaI of 83 rectaI carcinoid patients with tumor diameter Iess than 1. 5 cm were enroIIed. AII patients were pathoIogicaIIy diagnosed and underwent endoscopic mucosaI resection from Jan. 2008 to Dec. 2013 at Chongqing Three Gorges CentraI HospitaI and Wuhan Tongji HospitaI. The medicaI records were retrospectiveIy reviewed and expression of Ki-67 in tumor tissue was assessed by immunohistochemistry. Results:AII patients underwent preoperative endoscopic uItrasonography. Tumors were Iimited to mucosa or submucosa, and no muscuIaris propria invoIvement or metastasis was seen. The mean foIIow-up duration was 38 months,and no recurrence or metastasis occurred. Ki-67 was IowIy expressed in aII rectaI carcinoids(0. 84% ± 0. 67%). When tumors were grouped by size,no significant differences in gender,age,tumor site and Ki-67 expression IeveI were seen between <1. 0 cm group and 1. 0-1. 5 cm group(P >0. 05). Furthermore,when tumors were grouped by a cutoff vaIue of mean Ki-67 index 0. 84%,differences in cIinicopathoIogicaI parameters between the two groups were not significant either( P >0. 05 ). Conclusions:Ki-67 is IowIy expressed in rectaI carcinoids Iess than 1. 5 cm in diameter enroIIed in this study,which denoted an inactive proIiferation. For rectaI carcinoids with diameter Iess than 1. 5 cm,with Iow Ki-67 expression and without muscuIaris propria invoIvement and metastasis, IocaI endoscopic excision is an effective and safe treatment modaIity.

Objective To analyze related factors for pacemaker pocket infection in elderly patients after implantation of permanent pacemakers and to provide a theoretical basis for preventing pacemaker pocket infection.Methods Pacemaker pocket infection and related factors were analyzed for 412 patients who received implantation of permanent pacemakers from Apr.2010 to Jun.2013 in the Department of Cardiology.Results With 5 cases of pacemaker pocket infection,the rate of infection was 1.2％.The infected patients were older than the uninfected patients [(74.5±4.2) years vs.(60.3±6.6) years,t=4.781,P＜0.01].The rate of infection was higher in patients who had undergone operations twice or more than in patients who had undergone one operation [10.0％ (3/300) vs.0.5％ (2/382),x2=10.583,P＜0.01].The rate of infection was higher in patients with the operation lasting 2 hours or longer than in patients with the operation time shorter than 2 hours [(3.8％ (4/106) vs.0.3％ (1/306),x2=7.802,P＜0.01].The rate of infection was higher in patients with pocket hematoma than in patients without pocket hematoma [16.7％ (3/18) vs.0.5％(2/394),x2=37.492,P＜0.01].Independent risk factors for pacemaker pocket infection included pocket hematoma (OR=6.193),number of operations≥2 (OR=2.594),operating time≥2 hours (OR=2.265) and age of 75 years or older (OR =2.193).Conclusions Pocket infection after implantation of permanent pacemakers is related to pocket hematoma,number of operations,operating time and age.

BACKGROUND:Neural stem cel transplantation provides an important way to treat sequela of traumatic brain injury, but the timing for treatment is inconclusive.
OBJECTIVE:To explore the clinical effect of neural stem cel transplantation in the treatment of sequela of traumatic brain injury and the choice of the best treatment time.
METHODS: Totaly 178 patients with sequela of traumatic brain injury who underwent neural stem cel transplantation were divided into three groups as per the timing for neural stem cel transplantation: group A (with 6 months after injury,n=60), group B (6-12 months after injury,n=59), and group C (over 12 months after injury,n=59). Improvement in clinical symptoms and scores on function independent measure (FIM) were recorded and compared in the three groups.
RESULTS AND CONCLUSION:The total effective rate of group A was significantly higher than that in groups B and C (P < 0.05). FIM scores were significantly improved in the three groups after cel transplantation (P < 0.05). At 3 months after the fourth transplantation, the FIM score in the group A was significantly higher than that in the other two groups, and the incidence of adverse reactions in the group A was significantly lower than that in the other two groups (P < 0.05). These findings indicate that neural stem cel transplantation at different timing can al harvest certain clinical effects, but the best timing for neural stem cel transplantation is within 6 months after injury.
