Objective To observe the effects of tissue factor pathway inhibitor(TFPI) on thrombosis formation in rabbit carotid arteries after ballon injury. Methods Fouty rabbits with the weight 2.5-3.0 kg were respectively divided into 4 groups, Ad-TFPI, Ad-LacZ, PBS and normal control groups. The normal control group was not given any treatment and other 3 groups were given 0.2 ml Ad-TFPI, Ad-LacZ or PBS reproduced by the Dispatch catheter respectively after the PTCA balloon iniury on the right carotid arteries. Ten days after gene transfer the repeated balloon injury was performed in the 3 groups, and the first balloon injury was performed in the normal control group by the same method. The carotid blood flow was recovered immediately after the injury. Thirty minutes later all the animals were sacrificed. The injured carotid arteries and one part of contralateral normal artery were cut down, scissored along the long axis, flattened and fixed in the 2% glutaral. The platelet aggregation and thrombosis formation on the luminal surfaces was observed under electron microscope. Results The electron microscope results showed that the vascular endothelial cell structure was integrated and lined up in order in the nomal artery which had no any injury. After the balloon injury in the normal control group, the structure of the endothelial cell was disintegrated, and there was some platelet aggregation but no fibrosis formation. A large amount of platelet aggregated but no fibrosis formed in Ad-TFPI group after the repeated balloon injury. A large amount of fibrosis formed and red cells piled up in the Ad-LacZ and PBS group. The positive rate of thrombosis formation among groups had siginificant differences(χ2=14.95, P<0.01). The positive rate in Ad-TFPI group(20%) was lower than that in Ad-LacZ group(80%, χ2=7.20, P<0.01) and PBS group(70%, χ2=5.05, P<0.05), but was higher than that in the normal control group(10%, χ2=0.39, P>0.05). The positive rate in Ad-LacZ group(80%) was higher than in the normal control group(10%, χ2=9.90, P<0.01) and in the PBS group(70%, χ2=0.27, P> 0.05). The positive rate in PBS group(70%) was higher than that in the normal control group(10%, χ2=7.50, P< 0.01). Conclusions The repeated balloon injury method can cause a large amount of fibrosis formation in the rabbit carotid. TFPI gene inhibits thrombosis formation in balloon-injured rabbit carotid arteries.

Objective To investigate the effect of hyperacute intensive antihypertensive treatment on the prognosis of intracerebral hemorrhage in basal ganglia region. Methods From January 2013 to December 2015,100 patients with intracerebral hematoma in basal ganglia region (onset ≤3 h)at the Neurological Intensive Care Unit,the First Affiliated Hospital of Dalian Medical University were enrolled prospectively. They all randomly received the intensive antihypertensive or standard antihypertensive treatment voluntarily. They were divided into either an intensive antihypertensive group or a standard antihypertensive group according to the random number table (n = 50 in each group). Within 1 h after beginning to treatment,the target systolic blood pressure was controlled in 130 -140 mmHg in the intensive antihypertensive group,the target systolic blood pressure was controlled in 160 -180 mmHg in the standard antihypertensive group,and the target systolic blood pressure was maintained respectively in the following 7 d. Head CT was performed gain at 24 h after treatment. The intracranial hematoma expansion was evaluated. The National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS)were used to
evaluate their prognoses. The differences of the cumulative mortality in both groups were compared at the same time. Results The incidences of hematoma expansion of the intensive antihypertensive group and the standard antihypertensive group were 12. 0% (6/ 50)and 30. 0% (15/ 50)respectively. There was significant difference between the 2 groups (χ2 = 4. 882,P = 0. 027). There were no significant differences in NIHSS scores within or between both groups at each time points (all P > 0. 05). They were followed up for 90 d,no adverse events occurred in both groups. The favorable prognosis rates of the neurological function were 36. 0% (18 / 50)and 18. 0% (9 / 50)respectively in the intensive antihypertensive group and the standard antihypertensive group. There was significant difference between the 2 groups (χ2 = 0. 411,P =0. 043). Kaplan-Meier curves showed that the cumulative mortality at 24 h,within 7 d and 90 d in the intensive antihypertensive group and the standard antihypertensive group were 4. 0% (2 / 50),6. 0%(3 / 50),and 10. 0% (5 / 50),respectively,those of the standard antihypertensive group were 10. 0%(5 / 50),24. 0%(12 / 50),and 30. 0%(15 / 50),respectively. The results of Log-rank test found that there was significant difference in cumulative mortality between the 2 groups (χ2 =6.280,P =0.012). Conclusions The intensive antihypertensive treatment in the hyperacute cerebral hemorrhage is safe and feasible in basal ganglia region. It contributes to improve prognosis of neurological function,and reduce the incidence of hematoma expansion and the 90 d cumulative mortality.

OBJECTIVETo evaluate the effect of laparoscopic surgery in resection of suspected gastrointestinal stromal tumors.

METHODSA retrospective analysis was conducted among 50 patients with suspected gastrointestinal stromal tumors. All the patients underwent laparoscopic tumor resection. Thirty-eight of the patients had a preoperative diagnosis of gastric submucosa tumor by gastroscopy, and 12 had a diagnosis of small intestinal tumor by small intestinal endoscopy. The surgical procedure, operative time, estimated blood loss, time for passage of flatus, time for eating, postoperative hospital stay, operative complications, pathology and the results of follow-up were analyzed.

RESULTSIn these cases, the mean operative time was 90.84-/+26.69 min, with the mean estimated blood loss of 57.80-/+67.48 ml, mean time for passage of flatus of 50.90-/+18.87 h, mean time for eating of 2.94-/+0.79 days, and postoperative hospital stay of 8.62-/+3.56 days. No patient developed surgical complications, and all the lesions showed negative results on the margins of the resection.

CONCLUSIONAs a minimally invasive surgical approach, laparoscopic resection of suspected gastrointestinal stromal tumors reduces the intraoperative blood loss, promotes postoperative recovery of the patients and achieves R0 resection without causing serious complications.

OBJECTIVETo evaluate the feasibility, safety, radicality and short-term outcome of laparoscopic total mesorectal excision(TME) in comparison with open procedure for the middle-lower rectal cancer.

METHODSFrom November 2005 to October 2008, 93 patients with middle-lower rectal cancer received laparoscopic total mesorectal excision (LTME group), while 105 patients underwent conventional open TME (OTME group). The operative procedures, clinicopathological data and short-term outcome were collected and compared between the 2 groups.

RESULTS(1) Comparison of surgical procedures. The demographic data of LTME and OTME groups were comparable (P >0.05). Four (4.3%) patients were converted to open procedure in LTME group. The anal sphincter preserved procedure accounted for 82.8% in LTME group and 81.9% in OTME group. The difference was not significant (P >0.05). (2) Comparison of perioperative surgical data. The mean operating time was (164.6+/-35.6) min in LTME group, significantly longer than that in OTME group (141.9+/-29.4) min (P <0.001). The operative blood losses were (51.4+/-20.2) ml and (180.0+/-64.7) ml in LTME and OTME group respectively, the difference was significant (P <0.001). The analgesia requirement, time for bowel movement retrieval, time to liquid food intake, time to resuming early activity and hospital stay in LTME group were significant lower or shorter than those in OTME group (P <0.001). There was no operative death in both groups. (3) Comparison of operative complications. The overall morbidity rate was 11.8% in LTME group, and 12.4% in OTME group, the difference was not significant (P >0.05). The major complications were equivalent between two groups. (4) Comparison of specimen. No significant differences were observed between two groups in terms of specimen length, lymph node harvest and negative distal margin. (5) Follow-up results. The mean follow-up time was 19 months. The recurrent rate and overall survival rate were 4.4% and 97.8% in LTME group, with no significant difference compared to those in OTME group (7.3% and 97.9%, P >0.05).

CONCLUSIONSLaparoscopic TME for middle-low rectal cancer is safe and feasible, and can potentially offer all the benefits of a minimally invasive approach and achieve satisfactory oncological outcome,which may lead to a better future of the TME technique.
