OBJECTIVE:To explore the characteristics and clinical application of alginate dressing to provide better biological dressing for clinical wound healing.METHODS:A computer-based online search of CNKI,Medline,Wanfang,Science Direct,and Ei databases was performed for related articles published between January 1960 and October 2009,with the key words "alginate,dressing,clinical application"in Chinese and English.Studies regarding characteristics and clinical application of alginate dressing were included.Repetitive and Meta analysis were excluded.In addition,related books were manually searched.RESULTS:A total of 65 articles were collected,17 were included,and 48 repetitive or Meta analyses were excluded.Alginate is natural polysaccharide carbohydrate extracted from sea tangle,and alginate dressing is soft non-textile fiber refined from seaweed.It contains 85% natural alginate fiber and 15% sodium tvlose.It can absorb effusion,form gelate,and exchange Na+/Ca2+ with effusion.Alginate dressing has been widely used in bedsore treatment,anal fistula nursing,stoma nursing,and diabetic foot nursing.Compared with traditional dressing,infection rate of alginate dressing is lower due to good impermeability,promotion of regional vessel proliferation and blood supply,as well as moist and slightly acidic environment which benefits neutrophil function enhances disinfection.Moreover,it can be used in wound healing following abdominal region operation and abscess incision drainage.CONCLUSION:Alginate dressing provides appropriate environment for wound growth,retains active materials in diffusion,promotes active material release,benefit necrotic tissue solution and cell proliferation and differentiation,as well as epithelial cell migration.Moreover,it maintains hypoxia state of wound,stimulates newly generated capillary growth,and promotes granulation tissue growth.

Objective The purpose of the study was to investigate the correlation in incidence and severity between peripheral arterial disease(PAD) and coronary artery disease and stroke in Chinese people,in order to assess the essentiality of Ankle Brachial Index(ABI) examination for all the patients.Methods Patients hospitalized to Departments of Cardiology,Neurology and Vascular Diseases from March 2006 to December 2007 were enrolled.ABI was measured,and the disease history was collected.Ejection fraction(EF),coronary arteriography and ultrasound examination of the cervical artery were recorded to analyze the relationship between them and ABI.The prevalence of decreased ABI was calculated.Results In 132 patients hospitalized in the Department of Cardiology,the prevalence of ABI

Objective To investigate the clinical pathology characteristics of the p27 and C-myc protein expression in lung squamous cell carcinoma and adenecarcinoma as well as the correlation between the expressions of them. Method The expressions of p27 and C-mye protein in tumor tissue of 35 cases excised during pulmonectomy for lung squamous cell carcinoma and adenocarcinoma patients were examined using immunochemical method,and compared with 10 cases of normal lung tissue. Results The total positive rate of p27 protein was 17.1%(6/35 ) in 35 eases of tumor tissue, but 90.0%(9/10) in normal lung tissue, and there was significant difference (P< 0.05 ). Between high-moderate and low differentiated tissue,the positive rate had significant difference (P = 0.005). There was no significant difference of p27 protein expression in patients with different tumor size and histology types, as well as with or without lymph nodes metastasis (P > 0.05 ). The total positive rate of C-myc protein was 85.7% (30/35) in tumor tissue, but no expression existed in normal lung tissue (P < 0.05). There was significant difference of C-myc expressions between the tissue with and without lymph nodes metastasis (P =0.013),but there was no significant difference in various tumor size, differentiated degree, as well as histology type(P> 0.05). The expression of p27 and C-myc in lung squamous cell carcinoma and adenecareinoma showed negative correlation.Conclusions The expression of p27 protein is positive in normal lung tissue, but shows outstanding decrease in lung squamous cell carcinoma and adenocarcinoma tissue. Its expression correlates with the differentiated degree. The expression of C-myc is negative in normal lung tissue but shows significant increase in lung squamous cell carcinoma and adenocareinoma tissue and its expression correlates with lymph nodes metastasis. C-myc may be a valuable marker in evaluating prognosis.

RESULTS: A total of 65 articles were collected, 17 were included, and 48 repetitive or Meta analyses were excluded. Alginate is natural polysaccharide carbohydrate extracted from sea tangle, and alginate dressing is soft non-textile fiber refined from seaweed. It contains 85% natural alginate fiber and 15% sodium tvIose. It can absorb effusion, form gelate, and exchange Na~+/Ca~(2+) with effusion. Alginate dressing has been widely used in bedsore treatment, anal fistula nursing, stoma nursing, and diabetic foot nursing. Compared with traditional dressing, infection rate of alginate dressing is lower due to good impermeability, promotion of regional vessel proliferation and blood supply, as well as moist and slightly acidic environment which benefits neutrophil function enhances disinfection. Moreover, it can be used in wound healing following abdominal region operation and abscess incision drainage.CONCLUSION: Alginate dressing provides appropriate environment for wound growth, retains active materials in diffusion, promotes active material release, benefit necrotic tissue solution and cell proliferation and differentiation, as well as epithelial cell migration. Moreover, it maintains hypoxia state of wound, stimulates newly generated capillary growth, and promotes granulation tissue growth.

ObjectiveTo evaluate the efficacy of axillo-axillary bypass grafting for the treatment of contralateral arterial ischemia of upper limb. Method 53 cases underwent axillo-axillary artery PTFE graft bypass among those there were 46 cases of subclavian artery occlusion and 3 cases of subclavian artery aneurysm and 4 cases of trauma. Preoperatively 33 cases suffered from a symptom of extremity ischemia and 18 cases with subclavian artery blood steal. Result Good results were achieved in all cases without any complications. Doppler test showed the gradient of bilateral brachial pressure artery was less 10 mmHg in all cases. ConclusionAxillo-axillary artery PTFE graft bypass is an effective method for subclavian artery reconstruction with less trauma and complications. It is especially suitable for the elders with concomitant heart brain and lung diseases. It is also applicable for cases in which the subclavian arteries are not easily accessible due to artery aneurysm and artery trauma.

Objectives To study the diagnosis, treatment and prognosis of acute peripheral artery injury, and ways to improve the treatment. Methods Clinical data of 211 cases of acute peripheral arterial injuries admitted between January 1988 and June 2002 in Anzhen hospital were analyzed retrospectively. Of the 211 cases,73 cases were with blunt injuries, 99 penetrating injuries, 37 iatrogenic injuries, 2 gunshot injuries. Management procedures included arterial primary or patch repair in 28 cases, ligation alone in 17, end-to-end anastomosis in 41, interposition reverse saphenous vein graft in 37, interposition prosthetic graft in 29, thrombectomy in 14, excision of pseudoanurysm in 36, interventional thrombolytise in 2, ultrosonic-guided packing in 2, conservative management in 2. One hundred and ninety-two patients were cured,10 patients amputed, 4 patients died respectively.Results Ratio of cure,amputation,and mortality was 90.1%,4.74%,1.8% respectively.Amputation rate in blunt injuries was significantly higher than that in penetrarting injuries (P

Objective To summarize our experience in percutaneous transluminal angioplasty(PTA) in the management of thoracoabdominal aortic stenosis of Takayasu's arteritis. Methods From 1987～2001, 12 patients of Takayasu's arteritis with thoracoabdominal aortic stenosis underwent PTA. Aortography and pressure of stenotic segment of arota before and after angioplasty were used to evaluate efficacy. Color Doppler ultrasound examination and Doppler segmental pressure measurement were used in follow-up. Results Success was achieved in all cases without mortality and serious complications except for 1 case of acute thrombosis of iliofemoral artery. The residual stenosis were less than 50% in all cases and the pressure gradient was 5 0mmHg～10 5 mmHg with average pressure being 7 2 mmHg after angioplasty ,although they were 25mmHg～46 mmHg averaging of 37 7 mmHg before angioplasty. All cases were followed up for 9(12～72) months and the result was good without lumen restenosis and obstruction. Conclusions PTA is the first choice for Takayasu's arteritis of thoracoabdominal aortic stenosis of local size and proved to be safe, effectiveand economical. It is also effective for long size cases. It is not necessary to dilate aorta stenosis to normal size, and reducing pressure gradient effectively is enough.

Objective To investigate the effect of intratumor injection of 131 I 3H11 for gastric cancer (GC). Methods 16 patients with GC subjected to endoscopic intratumor injection of 131 I 3H11 as a treatment group; 6 GC patients with FAM chemotherapy as a control group. Histological examination of the postoperative specimens of the two group were comparated. Results In treatment group, 75.0%(12/16) of cases were found to have morphological changes with karyopyknosis, karyorrhexis, coagulation of cytoplasm, and invasion of lymphocyte in mesochyma. Most of these changes were medial; but in control group no obvious morphological change was found. Conclusions The results suggest that GC subjected to endoscopic intratumor injection of 131 I 3H11 preoperatively has promising application in the clinic.
