A Review] Endothelial cells produce both superoxide and nitric oxide. Nitric oxide and superox- ide are known to react rapidly to form the stable peroxynitrite anion. Peroxynitrite mediates the oxidation of protein, lipid, deoxyribose and inhibits mitochondrial electron transport. Peroxynitrite may break DNA strands and activate poly(ADP - ribose) syntheatase. If the reaction is excessive, it results in a depletion of intracelular NAD+ and ATP. There is ultimately cell death.

Objective:To explore the influence of liquid for post-operative irrigation on the effect of ESS.Method:192 cases with chronic sinusitis and/or nasal polyps of groupIIstageII who had undergone the ESS from September,1998 to June,1999 and completed a3-month follow-up were divided randomly into 3 groups to accept 3 different kinds of irrigation liquid.The evaluation of curative effect was according to the index of HaiKou ESS-97.Result:The curative effect of Herba Houttuyniae group was better than the other two.Conclusion:The post-operative care is important and the irrigation liquid can affect the effect of ESS.

Objective To observe the effect of unilateral ureter obstruction(UUO) on the expression of complement 5a receptor(C5aR) in rat renal tissue,and to investigate the roles played by C5aR in the development of renal intersititial fibrosis.Methods Thirty six male Sprague Dawley rats were randomly assigned into two groups(18 each): sham-operated group and UUO group.The left ureter of the rats in UUO group was obstructed,while in sham-operated group the left ureter was not.Six rats in each group were executed respectively on the 5th,10th and 15th day after surgery.Histological changes in renal tubular interstitium were observed with H.E.and Masson staining,and the expression of C5aR in renal tissues was detected by iminunohistochemical ELiVisionTM plus at each time point.Results Renal tubular dilatation and partial interstitial cells degeneration were found in UUO group on the 5th day after surgery.Necrosis of the interstitial cells was found in renal tubule,and the interstitial fibrosis was found on the 10th day.On the 15th day after surgery diffuse thickening and shrinkage of renal tubular basement membrane and obvious fibrosis were found(P0.05).Conclusion The C5aR expression in renal tissue increases significantly at the early stage of UUO,while the process is slowed down in the later stage.C5aR may take part in the process of renal intersititial fibrosis at the early stage.

Objective To explore the preliminary construction of nursing care quality index based on the characteristics of ophthalmic nursing. Methods Through literature review and experts′discussion, the preliminary construction of nursing care quality index were designed. The Delphi method was used to revise the indicators. Results After two rounds of Delphi procedure, the opinion of the experts became consistent. Questionnaire collecting rates of the two rounds were both 100％, and cooperation index were 0.236 and 0.292 respectively (P<0.01), two first level quality indicators were confirmed, namely ophthalmic care operations (five second level indicators) and health education (four second level indicators). Conclusion The ophthalmic nursing care quality indicators were scientific, reliable and feasible, which could provide objective and quantified basis for the management of nursing care quality.

Malignant tracheoesophageal fistula (MTEF) is pathological communication between the respiratory tracts such as the trachea or bronchia and the esophagus because of malignant tumor dissemination through them.Radiography is an important adjunctive technology in the diagnosis of MTEF,and the location and size of fistula often need the further diagnosis of bronchoscopy and esophagoscopy.The patients are often with an unfavourable prognosis once developed MTEF,and are treated usually with the aim of symptom palliation and life quality improvement.The individual treatment includes esophageal stenting,esophageal exclusion and esophagus bypass,fistula exclusion and repair,radiotherapy and others effective therapy according to the patients condition.These therapies will prolong the life span and improve the life quality of patients.MTEF is not absolute contraindication for chemoradiotherapy.Despite its acute toxicity,this concurrent chemoradiothe rapy protocol appears feasible and effective at closing esophageal malignant fistula,especially in patients in a good general condition and without metastasis.

Objective To study 18F-deoxyglucose-positron emission tomography and CT fusion (FDG PET) in three dimensional conformal radiotherapy for non-small -c ell lung carcinoma (NSCLC). Methods Gross tumor volume (GTV) of 13 NSCLC patient s were determined by FDG PET and CT separately (GTV PET-CT and GTV CT ), which were then compared. Results Except 2 patients, all the other patients' GTV PET-CT dif fered from their GTV CT. Compared with GTV CT, GTV PET-CT was in creased by an avera ge of 29.2?cm3 in 5 patients and decreased by an average of 41.6?cm3 in 6 patien ts. Conclusions 18F-deoxyglucose-positron emission tomography, which can improve target definition between benign and malignant lesions in the lung, is proved t o be more sensitive and specific in detecting mediastinal lymph node involvement . FDG PET may provide accurate target definition and improve the local control.

OBJECTIVEThis study aimed to compare the treatment effects of simultaneous surgical treatment and stage operation for patients with craniomaxillofacial fracture combined with other injuries.

METHODSFifty patients with maxillofacial fractures combined with other injuries were chosen and divided into simultaneous (28 patients) and staging (22 patients) operation groups. In simultaneous operation group, maxillofacial fracture reduction, internal fixation, and other parts of the surgery were simultaneously operated by relevant departments jointly. In the staging operation group, maxillofacial fracture reduction and internal fixation were performed after treatment of other injuries. Data on the treatment efficacy and associated injuries of the two groups were statistically analyzed.

RESULTSIn the simultaneous operation group, 26 patients had good occluding relation, the maximum mouth opening was (34.5 +/- 3.7) mm, the symmetry and shape of hard tissues recovered well, and the bone plate of one patient was removed because of internal fixation infection. In the staging operation group, 14 patients had good occluding relation, the maximum mouth opening was (28.5 +/- 3.5) mm, the symmetry and shape of hard tissues poorly recovered, and the bone plates of 5 patients were removed because of internal fixation infection. Statistical significance was determined among occluding relation, maximum mouth opening, postoperative complications, and length of stay of the two groups (P< 0.05). Treatment of the simultaneous operation group was more effective than that of the staging operation group.

CONCLUSIONWhen a patient's condition is relatively stable, simultaneous surgical treatment of multiple specialties should be conducted to treat craniomaxillofacial fracture combined with other injuries.

BACKGROUND:Previous studies have found that the susceptibility genes of adiponectin gene and calpain 10 gene of type 2 diabetes are closely related with the incidence of diabetes in Chinese renal transplantation patients. So, are other susceptibility genes of type 2 diabetes also associated with posttransplantation diabetes mel itus? OBJECTIVE:To investigate the association between the zinc transporter solute carrier family 30 member 8 (SLC30A8) gene polymorphism and the posttransplantation diabetes mel itus. METHODS:A total of 97 patients with posttransplantation diabetes mel itus and 301 patents without posttransplantation diabetes mel itus (control group) were selected, and then the SLC30A8 gene rs13266634 genotype was detected with real-time PCR method. The association between gene polymorphism and posttransplantation diabetes mel itus was analyzed with Logistic regression test. RESULTS AND CONCLUSION:There were significant differences in al ele frequencies and genotype distributions of rs13266634 between the patients with and without posttransplantation diabetes mel itus (P<0.05). After adjustments of age, sex, body weight and body mass index, the incidence of posttransplantation diabetes mel itus of the CC genotype patients was 2.108 times to that of the TT genotype patients (odds ratio=2.108, 95%confidence interval:1.075-4.131, P=0.044);and the incidence of posttransplantation diabetes mel itus of the CC+CT genotype patients was 1.862 times to that of the TT genotype patients (odds ratio=1.862, 95%confidence interval:1.049-3.306, P=0.034). The results suggest that the C-al ele in rs13266634 of SLC30A8 gene is the independent risk factor of posttransplantation diabetes mel itus.
