Digestive tract reconstruction is the main part of gastrointestinal surgery. With the rapid development of technology and widely application in stapling device, more and more surgeons are using stapled anastomosis. Stapled anastomosis is associated with shorter operating time and hospital stay than hand-sewn anastomosis. However, it is not easy to select suitable ones from various staplers and use them correctly. Choice and reasonable application of staplers for anastomosis in gastrointestinal surgery are summarized and evaluated in this article.

Objective To evaluate the diagnostic value of positron emission tomography(PET) with the use of 18 F-fluorodeoxyglucose(FDG) in patients with gastic malignancy. Methods 18 F-FDG PET examination was performed for twenty three patients suspected to be suffering from gastric malignancy,and the results were evaluated against histopathological staging. Results The diagnostic accuracy of primary lesion by PET was 87.0%. When using a mean standard uptake value (SUVmear and SUVmax) with a cut-off of 2.5,the sensitivity was 86.2%(19/23)and 91.3%(21/23),respectively. The accuracy in identifying lymph node metastases and distant metastases by PET was 78.9%(15/19) and 7/8,respectively. Conclusion PET scanning is sensitive in the diagnosis of primary malignant lesion and metastatic lesion in patients suspected to have gastric cancer. It provides a valuable reference in the diagnostic evaluation,option of surgical strategy,and treatment in patients with gastric carcinoma.

Objective To study the changes in the endothelial reserve capacity to release tissue plasminogen activator (tPA) and nitric oxide (NO) and its relation to vasodilation and to diabetic angiopathy. Methods The capacity of vascular endothelium to release tPA and NO was examined by venous occlusion of the upper arm. Brachial artery diameter was measured at baseline, during postocclusion reactive hyperemia (flow-mediated endothelium-dependent), and after sublingual nitroglycerol administration (endothelium-independent), using a high resolution ultrasound technique in 15 control subjects and 23 patients with type 2 diabetes mellitus. Vasodilation was expressed as the percentage change relative to the baseline diameter, while endothelial tPA and NO release was expressed as the percentage change relative to the baseline tPA and NO levels. Thickness of the intima of carotid artery was measured using ultrasound imaging. Results There was no significant difference in endothelium-independent vasodilation between control subjects and diabetics. However, significant reductions in endothelium-dependent vasodilation (P

Objective To determine the distribution and antibiotics resistance characteristic of pathogens in urinary tract infections in aged female diabetics patients and provide scientific basis for clinicians in selecting effective antibiotics. Methods Pathogenic bacteria, isolated from specimens of 107 elderly female diabetic cases with urinary tract infections, were identified and drug susceptibility tests were performed by VITEK-32 analysator. Results Among all 107 kinds of isolated bacteria,the ratio of gram-negative bacteria was 74. 8% ( 80/107 ), predominated by Escherichiacoli ( accounting for 48. 6% [52/107] ); the ratio of gramposition bacterias was 13. 1% (14/107) and eumycetes was 12. 1% (13/107). In antibiotic resistance analysis,the gram negative bacteria showed higher drug-resistance to the some common-antibiotics, such as ampicililin,cefazolin,cefuroxime-sodium and cefuroxime axetil ( ＞ 70. 0% ), while they were sensitive to imipenem and amikacin( ＜ 10. 0% ). The gram positive bacteria were most sensitive to vancomycin (0%), followed by Linezolid(7.7% ). Conclusion Escherichiacoli were the major pathogenic bacteria in urinary tract infections in aged female diabetic patients, with higher drug resistance. Therefore, drug resistance monitoring should be carried out according to the variety of pathogenic bacteria so as to guide rational use of antibiotics and decrease drug resistance.

The diagnostic evidence on clinical diseases and theoretic basis of moving cupping therapy were ex- plored in the paper. By the observation of the local reaction, such as skin appearance and color, the affected location, duration of sickness and nature of disease were judged. Different moving cupping methods were selected for different disorders. It was discovered that the property of syndromes should be recognized by the palpation on skin and muscle in the moving cupping therapy so that the pathogenesis and treating principle could be carefully determined. The moving cupping therapy is the important component of body surface therapy. Skin reaction observation and syndrome differentiation is the essential guidance of the moving cupping therapy.

?-MSH is an endogenous neuropetide that is effective of all categories of expreimental inflammation. The mechanisms underlying the anti-inflammatory influence of ?-MSH are reviewed in the article. ?-MSH suppresses inflammation in the CNS and periphery by downregulating the activation of NF-?B, then inhibiting production of proinflammatory cytokines, nitric oxide, chemokines and adhension molecules, and increasing synthesis of anti-inflammatory cytokines. ?-MSH is useful in the treatment of many pathological situations in humans.

α-MSH is an endogenous neuropetide that is effective of all categories of expreimental inflammation. The mechanisms underlying the anti-inflammatory influence of α-MSH are reviewed in the article. α-MSH suppresses inflammation in the CNS and periphery by downregulating the activation of NF-κB, then inhibiting production of proinflammatory cytokines, nitric oxide, chemokines and adhension molecules, and increasing synthesis of anti-inflammatory cytokines. α-MSH is useful in the treatment of many pathological situations in humans.

Objective To evaluate the clinical effectiveness of perioperative fast-track surgery(FTS)program and nutrition support in the elderly patients with gastric cancer.Methods Totally 42 patients were equally randomized into FTS group(receiving perioperative FTS program)and control group(receiving a conventional therapy).The postoperative first defecation time,postoperative hospital stay,hospitahzation expenditure,and postoperative complications were compared between these two groups.Results The postoperative first defecation time and postoperative hospital stay were(75.4±24.3)hours and(11.2±3.2)days in FIS group and(98.0±22.6)hours and(14.4±4.6)days in control group(P=0.0165,P=0.0004;respectively).The hospitalization expenditure was significantly lower in FTS group than in control group[(3.66±0.48)×104 vs.(4.56±0.78)×104 RMB yuan;P=0.0001].The incidence of postoperative complications in FTS group was also significantly lower than that in control group(9.5% vs.28.6%,P=0.0422).Conclusion Perioperative FTS program can accelerate postoperative rehabilitation,shorten hospital stay,lower hospitalization expenditure,and reduce the incidence of postoperative complications.
