Objective To observe the effect of new moist dressings on pressure ulcers after spinal cord injury. Methods 58 spinal cord injured patients complicated with pressure ulcers were divided into observation group (n=29) and control group (n=29). The observation group accepted moist dressings, while the control group accepted routine dry dressings, TDP and ultraviolet irradiation. The incidence of im provement were recorded 2 weeks after treatment, and the time of healing were compared. Results 11 cases cured, 17 cases relieved in the observation group, and it was 5 and 18 cases in the control group, respectively (P<0.05). It spent (26.69±16.48) days to cure in the observa tion group, and (38.24±22.47) days in the control group (P<0.05). Conclusion The moist therapy may promote the cure of pressure ulcers af ter spinal cord injury, and shorten the time of cure.

Metabolic syndrome( MS) is a group of clinical symptoms,which is based on the pathophysiol-ogy of insulin resistance that mainly includes obesity,hyperglycemia,hypertension,dyslipidemia,nonalcoholic fatty liver disease and other components.In recent years,many studies have suggested that the occurrence of colorectal cancer( CRC) is closely related with the MS components.This article reviews the research progress on the associa-tion between the major components of MS and the pathogenesis of CRC.

Objective To investigate the effect of pantoprazole (proton pump inhibitor, PPI) and gefarnate (gastric mucosa protectant) on the prevention of upper gastrointestinal bleeding in patients undergoing post-percutaneous coronary intervention (PCI) dual anti-platelet therapy.Methods This research included 1263 patients taking enteric aspirin and clopidogrel after PCI.The cases were divided into 4 groups: routine treatment group (n=332), PPI group (n=318), gastric mucosa protectant group (n=299), and PPI+gastric mucosa protectant group (n=314).A follow-up for 6 months was observed including gastrointestinal symptoms, upper gastrointestinal bleeding, major adverse cardiac events (MACE), and adverse reactions.Results There were 52 cases of upper gastrointestinal bleeding within 6 months, including 21 cases from routine treatment group, 9 from PPI group, 15 from gastric mucosa protectant group, and 7 from PPI+gastric mucosa protectant group.The incidence of upper gastrointestinal bleeding among the 4 groups within 6 months was statistically different (X2=8.883, P=0.031).The routine treatment group had significant higher rate than the PPI group and the gastric mucosa protectant group (P<0.05), while among other groups there was no significant difference (P>0.05).The upper gastrointestinal bleeding occurred within 3 postoperative months in 34 out of 52 cases (65.4%).There was no statistical significance among the four groups in regard to bleeding occurrence time (X2=4.212,P=0.648).Conclusions Patients undergoing post-PCI dual anti-platelet treatment can reduce the incidence of gastrointestinal bleeding by taking pantoprazole or combined with gefarnate.Intervention against upper gastrointestinal bleeding should start on the first day after PCI and last for a minimum of 3-6 months.

Objective To investigate the expression of Rap1 GTPase-activating protein 1 (Rap1GAP),matrix metalloproteinase 2 (MMP-2) and matrix metalloproteinase 9 (MMP-9),and their relation with clinical patterns in colorectal carcinoma.Methods Immunohistochemistry was used to detect the expression of Rap1GAP,MMP-2 and MMP-9 in colorectal carcinoma,villous adenoma,tubular adenoma and normal colorectal tissue,and their relationship with clinicopathological parameters was analyzed.Results The positive rate of Rap1GAP expression was 30.4 ％ (14/46),77.8 ％ (14/18),69.6 ％ (16/23) and 95.2 ％ (20/21) in colorectal carcinoma,villous adenoma,tubular adenoma,and normal colorectal tissue,respectively (x2 =30.659,P=0.000).The figures were 71.7 ％ (33/46),55.6 ％ (10/18),52.2 ％ (12/16) and 9.5 ％ (2/21) for the positive rate of MMP-2 expression (x2 =22.459,P =0.000),as well as for 76.1％ (35/46),61.1％ (11/18),56.5 ％ (13/23) and 14.3 ％ (3/21) for the positive rate of MMP-9 expression,respectively (x2 =22.643,P =0.000).In patients with colorectal carcinoma,the expression of Rap1GAP was correlated with tumor differentiation (x2 =5.275,P =0.022),but not sex,age,or lymphatic metastasis (all P ＞ 0.05).The expression of MMP-2 and MMP-9 were correlated with lymphatic metastasis (x2 =6.661,P =0.010;x2 =8.475,P =0.040),but not sex,age or tumor differentiation(all P ＞ 0.05).There was a negative correlation between expression of Rap1GAP and MMP-2,MMP-9 in colorectal carcinoma,respectively (r =-0.424,P =0.003;r =-0.294,P =0.048),but no correlation between the expression of MMP-2 and MMP-9 (r =0.101,P =0.505).Conclusions Rap1GAP,MMP-2 and MMP-9 play important roles in the malignant biological behavior of colorectal carcinoma,and the expression of Rap1GAP is negatively correlated with MMP-2 and MMP-9.The interactions among the three affect the occurrence and development of colorectal carcinoma.

Objective To discuss the advantages of balloon combined with stent-assisted steel-coil embolization in treating intracranial wide-necked aneurysms located at artery bifurcation sites. Methods The clinical data of 20 patients with intracranial wide-necked aneurysms located at artery bifurcation sites (25 aneurysms in total), who were admitted to the First Affiliated Hospital of Kunming Medical University during the period from January 2014 to May 2014 to receive balloon combined with stent-assisted steel-coil embolization treatment, were retrospectively analyzed. Among the 20 patients, 16 had a history of subarachnoid hemorrhage and 4 had no history of subarachnoid hemorrhage. A total of 25 intracranial aneurysms located at artery bifurcation were detected; the locations included basilar terminal bifurcation (n=14), middle cerebral artery (MCA) bifurcation (n=8) and internal carotid artery (ICA) bifurcation (n=3). Three dimensional DSA was performed immediately and three months after the treatment , and the manifestations were evaluated according to Raymond classification. The clinical efficacy at three months after the treatment was assessed with the modified Rankin scale (mRS). Results Three dimensional DSA performed immediately after the balloon combined with stent-assisted steel-coil embolization treatment showed that among the 25 intracranial wide-necked aneurysms located at artery bifurcation 21 belonged to Raymond gradeⅠ, 2 belonged to Raymond grade Ⅱand 2 belonged to Raymond grade Ⅲ. Follow-up DSA performed three months after the treatment revealed that 20 aneurysms were Raymond grade Ⅰ, 3 aneurysms were Raymond gradeⅡand 2 aneurysms were Raymond grade Ⅲ. Three months after the treatment the mRS score was 0 point in 17 patients and one point in one patient, and the prognosis of these patients was good; the mRS score was 4-6 points in 2 patients, and the prognosis of the two patients was poor. Conclusion For the treatment of intracranial wide-necked aneurysms located at artery bifurcation sites, balloon combined with stent-assisted steel-coil embolization has obvious advantages.
