Objective To investigate the means which can prevent postoperative incision infection of elderly patients with obstructive colorectal cancer. Methods Sixty-seven cases of elderly patients with obstructive colorectal cancer adopting surgical treatment were divided into two groups, including experimental group with 37 cases and control group with 30 cases. Put self-made negative pressure drainage tube with side-hole into subcutaneous interspace of abdominal incision of experimental group alter operation, kept continuous negative pressure drainage 7-10 d and pull out the self-made subcutaneous negative pressure drainage tubes till drainage volume decreased obviously. The abdominal wall incisions of the control group were given conventional suture. Results Incision infection occurred in only one case (2.7%) and no incision dehiscence occurred in the experimental group, and incision healing time was (9.36 ± 2.18) d. Incision infection occurred in 7 cases (23.3%) in the control group, of which there were 3 cases (10.0%) of wound dehiscence, incision healing time was (12.25 ±4.06) d. Incision infection rate of the two groups had significant difference (χ2= 6.706,P < 0.05), incision dehiscence rate of the two groups had no significant difference (P 0.05), incision healing time of the two groups had significant difference (t = 6.676, P < 0.05). Conclusion Using the self-made subcutaneous negative pressure drainage tube and keeping it continuous negative pressure drainage after operation can be effective in preventing incision infection of elderly patients with obstructive colorectal cancer, and promote wound healing.

Objective To explore the safety,efficacy and clinical significance of stenting with cerebral protection devices for carotid artery stenosis.Methods 14 patients with carotid artery stenosis were treated by intra-arterial stents implanted.All of them used cerebral protection of filter devices.Results 18 self-expandable stents were successfully implanted in 14 patients.Of them,stroke ictus caused by microemboli in 2 patients ,and they recovered after treatment for 1~3 d,6 patients had transient bradycardia and hypotension.No cerebral infarction could be seen in all cases during the follow-up period.Conclusion Carotid setenting with cerebral protection devices is an effective and safe method in treating carotid stenosis,and it is helpful to reduce the neurological complication.

In recent years,with the development of neuroimaging and the progress in related clinical studies,people have had a better understanding of posterior circulation ischemia.This article reviews the progress in the causes,mechanisms,clinical manifestations,diagnosis, treatment and prognosis of posterior circulation ischemia.

Objective To compare the difference of serum heme oxygenase-1 (HO-1) and carbon monoxide(CO) levels between the patients with coronary heart disease(CHD) caused chronic heart failure(CHF) and CHD patients with normal cardiac function,and further to explore the protective mechanism of HO-1/CO system during the pathogenesis process of CHF.Methods Ninety-one patients with CHF were selected as the observation group and 72 CHD cases with normal cardiac function were taken as the control group.The concentration of HO-1 was determined by ELISA arid the Chalmer S method was used to detect serum CO concentration.The general clinical data of the two groups were recorded by the using the heart failure questionnaire.And the liver and kidney functions,blood lipids,NT-proBNP,BNP and cardiac echocardiography examination were performed.Results The serum HO-1 level in the observation group was (8.13±0.27)ng/mL,which was higher than (2.80±0.52)ng/mL in the control group;the CO level in the observation group was (0.35±0.06)mg/L,which was lower than(0.59±0.07)mg/L in the control group,the difference was statistically significant(P＜0.01);the HO-1 level in the observation group was gradually increased with the increase of cardiac function grade (P＜0.01);while the CO level was decreased with the increase of cardiac function grade (P＜0.01).Conclusion The serum HO-11evel in the patients with CHF is highly expressed with the heart failure aggravation;endogenous CO is gradually decreased due to consumption after cardiac failure aggravation.

Objective To investigate the inhibitory effects of PPARγ ligand rosiglitazone in vivo of mice which were transplanted the human gastric carcinoma cells line MGC803 into subrenal-capsule.Methods To establish kunming mouse tumor modles of MGC803 cells transplanted into subrenal-capsule and assay the inhibiting growth effects of 50 mg／kg rosiglitazone which were continuously poured into mice gastric for five days by the dissect microscope and HE stain.Results Rosiglitazone could inhibit the growth of MGC803 cells transplanted into subrenal-capsule of mice in vivo by inhibiting proliferation and inducting apoptosis,the tumor inhibitory rate was 62.9％.Conclusion PPARγ ligand rosiglitazone can inhibit the growth of MGC803 cells transplanted into subrenal-capsule of mice in vivo.
