Objective To compare the saccharometabolism with the pancreatic islets functions and insulin resistance index in children with severe stress. Methods Thirty children with severe stress and 30 healthy children in control group were tested. The levels of fasting blood glucose (FBG), fasting insulin (FINS) and fasting C - peptide (FCP) were detected by radioimmunoassay respectively and insulin sensitivity index (ISI), insulin resistance index (IR) and fasting blood cell function index (FBCI) were calculated statistically. Results There were significant differences between the children with severe stress and the normal controls in the levels of FINS, FCP and FBG,(all P0.05). Conclusion There is insulin resistance with the significant decrease in the insulin sensitivity index and significant increase in insulin resistance index in the children with severe stress, which may cause the disorder in glucose metabolism in children with severe stress.

OBJECTIVETo investigate the relationship between the promoter polymorphism of IL-4 and IL-6 and chronic rhinosinusitis (CRS).
METHODSOne hundred and twenty-three patients with CRS and 239 healthy controls in Shanghai region were chosen in this study. The genotype of IL-4 gene -33T>C and -590C>T were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method and the genotype of IL-10 gene -1082A>G was determined using amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) method. Statistical calculations were performed using SAS 8.2 software.
RESULTSSignificant differences were found in genotype distribution of -33T>C and -590C>T between the CRS group and the control group (χ2=6.6013, P=0.0102, χ2=6.6013, P=0.0304), and -33T>C remained significant following application of the Bonferroni correction (P<0.025). The relative risks of CRS with -33T>C and -590C>T were 1.818(P=0.0236, 95%CI 1.084-3.050) and 1.838 (P=0.0147, 95%CI 1.127-2.997). There was linkage disequilibrium (LD) between the -33T>C and -590C>T. The coefficient of linkage disequilibrium (D') was 0.77 and the related coefficient (r2) was 0.54. The -33T/-590T haplotype was associated with CRS and the relative risk was 1.653 (P=0.0130, 95%CI 1.107-2.469). There were only two genotypes of IL-10 gene-1082A>G and the frequencies of the AA and AG genotypes were not different between the CRS and control groups.
CONCLUSIONThe promoter polymorphism of IL-4 -33T>C and -590C>T were associated with the susceptibility of CRS and the -33T/-590T haplotype was a risk factor for CRS, but there were no association between the -1082A>G and CRS.

OBJECTIVETo study the combination of trans-anal intersphincteric resection and transabdominal total mesorectal excision for anus-retained ultra-low rectal tumors.
METHODSClinical data of 34 ultra-low rectal tumor patients without external anal sphincter involved, who underwent the combination surgery, were retrospectively analyzed.
RESULTSThe distance from the distal incisal margin of the rectum to the inferior margin of the tumor ranged from 1.8 cm to 3.0 cm on an average of 2.1 cm. For pathological types, there were 23 cases of adenocarcinoma (9 well differentiated and 14 moderately differentiated), 1 papillary carcinoma, 2 rectal stromal tumor, 5 rectal villous adenoma with neoplasia and 3 giant villous adenoma. For pathological stages, there were 18 cases at stage pTNM I, 5 at IIA, 1 at IIB, 4 at IIIA, 1 at III and for T grading, there were 15 cases at stage T1, 5 at T2, 8 at T3, 1 at T4. In these 34 patients, there were 3 cases with postoperative anastomotic stenosis, 2 with postoperative anastomotic rupture, 2 with rectovaginal fistula and no operative death. Because of the dysfunction of bowel control, bowel frequency varied from 3 to 12 in the early stage after operation, but with the recovery of anus function, bowel frequency decreased and ranged form 1 to 5 times a day and the time of formed bowel control could be more than 5 min in 6-12 months after operation. However, patients underwent total resection of internal anal sphincter still suffered from incontinence of loose stool after 1 year. After operation, anastomotic recurrence was found in 1 case in 5 months, liver metastasis in 1 case in 10 months and 28 months respectively, cardiac sudden death in 1 case in 26 months.
CONCLUSIONThe combination of trans-anal ISR and trans-abdominal TME for anus-retained ultra low rectal tumor is not only coincident with radical tumor principle but also retains the function of anus, on the premise of the strict indication.

AIM:To investigate the molecular mechanism of wogonin on the growth and invasion of oral squa -mous-cell carcinoma (OSCC) cell line SCC-4.METHODS:After treatment with various doses (0, 20, 40, 60, 80 and 100 mg/L) of wogonin for the indicated time , MTT assay was used to evaluate cell viability .The cell apoptosis was detec-ted by flow cytometry with Annexin V and propidium iodide (Annexin V/PI) double staining.The cell invasion ability was analyzed by Transwell assay .The activation of Wnt/β-catenin signaling molecules was assessed by Western blot .RE-SULTS:Wogonin inhibited the viability and invasion of SCC-4 cells but promoted cell apoptosis in a dose-and time-de-pendent manner .Wogonin treatment obviously decreased the activation of β-catenin.Moreover, the expression of down-stream targets cyclin D1, matrix metalloproteinase-2 (MMP-2) and MMP-9 were obviously down-regulated, accompanied by the up-regulation of anti-apoptotic protein Bcl-2.Wnt/β-catenin activator LiCl remarkably attenuated the inhibitory effect of wogonin on the activation of Wnt/β-catenin signaling molecules .Importantly, the inhibition of cell growth and in-vasion ability by wogonin treatment was dramatically attenuated after LiCl exposure .CONCLUSION: Wogonin blocks SCC-4 cell growth and invasion mainly by regulating Wnt/β-catenin signaling , indicating that it is a potential suppressor for OSCC and may be a potential target for the development of anti-OSCC therapy .

OBJECTIVETo explore etiologic fraction (EF) and interaction of serum hepatitis B surface antigen (HBsAg) carriage and other risk factors for primary hepatocellular carcinoma (PHC) in Wenzhou, Zhejiang, China.
METHODS1:1 matched case-control study was carried out in Wenzhou, with 180 cases of PHC and 180 controls. EF and interactions of serum positive HBsAg [HBsAg(+)] and other risk factors for PHC were analyzed by Mantel-Haenszel stratified method and conditional multiple logistic regression.
RESULTSSerum HBsAg(+), poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events all were risk factors for PHC, with EFs of 0.728, 0.245, 0.224, 0.084, and 0.234, respectively. There existed interactions of HBsAg(+) with other risk factors, including poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events, with etiologic fractions attributable to interaction [EF (A x B)] of 0.770, 0.630, 0.848, and 0.627, and indices of interaction of 0.789, 0.638, 0.852, and 0.634, respectively.
CONCLUSIONSMain risk factor for PHC in Wenzhou, Zhejiang, China could include HBsAg(+), poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events. HBsAg(+) plus any of the following factors, such as poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events, could increase the risk of PHC.

OBJECTIVETo evaluate the perineal rectosigmoidectomy(Altemeier procedure) in the emergent management of acute incarcerated rectal prolapse.
METHODSClinical and follow-up data of 9 patients with acute incarcerated rectal prolapse undergone Altemeier procedure were retrospectively analyzed.
RESULTSThe mean operation time was 1.7 (range 1.0-1.5) hours. The mean total blood loss during surgery was 109 (50-200) ml. The mean time to the first bowel movements was 2.8(1-6) days after surgery. The hospital stay was 5.3(3-10) days. There were no postoperative complications such as anastomotic leakage, intra-abdominal infection, or urogenital dysfunction. One patient developed thrombosis in the mesorectum and one patient had symptoms of anal discomfort. After a mean follow-up of 3.5(5 months-6.5 years) years, no patient had recurrent prolapse. Six months after operation, anal function was Kirwan grade I( in 8 cases and grade II( in 1 case. All the patients were satisfied with the result.
CONCLUSIONAltemeier procedure can result in good postoperative anal function when treating incarcerated rectal prolapse, which should be the first choice in emergency treatment.

OBJECTIVETo investigate the value of protective stoma in intersphincteric resection (ISR) for ultra-low rectal cancer.
METHODSClinical data of 56 ultra-low rectal cancer patients without involvement of external anal sphincter treated during January 1999 to July 2009 with trans-anal ISR plus trans-abdominal total mesorectum excision and coloanal anastomosis were retrospectively analyzed. The patients were divided into two groups based on whether they received protective ostomy: ostomy group (16 cases) and ostomy-free group (40 cases). The postoperative complications as well as anal functional restoration were compared between the two groups.
RESULTSSixteen cases (32.1%) of the 56 patients received protective stoma. The complication rate of anastomosis and anus complication rate in the ostomy-free group were significantly higher than those in ostomy group [35.0% (14/40) and 40.0% (16/40) vs. 1/16 and 1/16; P < 0.05]. In the ostomy-free group, one patient developed anastomotic dehiscence and tumor recurrence, the patients was given permanent colostomy, and the other three patients with lesions in the anastomosis and anus received ostomy and secondary surgical treatment, with a reoperation rate of 10.0% (4/40). The anal function of patients in the two groups were both decreased after the operation. The rate of patients got Kirwan grade I anal sphincter function in the 3rd, 6th and 12th month after protective stoma operation was 11/16, 13/15 and 11/13 in the ostomy group, respectively; and those were 30.0%, 37.5% and 45.0% in the ostomy-free group, respectively. Anal function was significantly better in the ostomy group than that in the ostomy-free group during the same postoperative period (P < 0.05).
CONCLUSIONProtective stoma can avoid anastomotic leakage following ISR for ultra-low rectal cancer, and alleviate the suffering of anal incontinence in the early postoperative period, and is conducive to the restoration of anal function.

OBJECTIVETo investigate the clinical application of intersphincter resection (ISR) combined with total mesorectal excision (TME) and colon-anal anastomosis in the treatment for ultra-low rectal carcinoma.
METHODSTo review and analyze retrospectively the data of 34 patients with ultra-low rectal carcinoma (without external anal sphincter involvement) who received treatment of ISR, TME and colon-anal anastomosis.
RESULTSPartial resection of internal sphincter was performed in the patients with a distal edge of the tumor greater than or equal to 2 cm from the dentate line. Subtotal removal of the rectum was performed between 1 cm and 2 cm. Total resection was performed in less than 1 cm or involvement of dentate line. Reconstruction of digestive tract was done by manual colon-anal anastomosis. The average distance from distal excised margin to the tumor was 2.3 (1.8 - 3.2) cm among 34 patients. The pathological types were as follows: 28 cases of adenocarcinoma (11 were well differentiated, 17 moderately differentiated), 1 case of papillary carcinoma and 5 cases of villous adenoma with malignant change. The postoperative pathological stages were: Dukes stage A in 28 cases, stage B in 1 and stage C in 5 cases. The pTNM staging was 28 cases in phase I, 1 in phase IIa, 4 in phase IIIa and 1 in phase IIIb. The T stages of the patients were as following: 16 Tl, 17 T2 and 1 T3. Postoperative anastomotic stenosis occurred in 3 cases, anastomotic dehiscence in 2 cases and rectovaginal fistula in 2 cases. The ability of controlling feces of patients decreased significantly in the early postoperative period, and restored gradually at 6 to 12 months after operation. Anastomotic recurrence occurred in 1 case at 5 months after operation and liver metastasis in 1 case at 40 months.
CONCLUSIONWith strictly grasping indications, radical resection can be attained and anal sphincter preserved by ISR combined with TME and colon-anal anastomosis. It is an effective sphincter-preserving operation.

OBJECTIVETo study the transmission route of severe acute respiratory syndrome (SARS) nosocomial infection.
METHODSTen identified SARS patients were selected from a general hospital in March. Survey was carried out through a standardized questionnaire provided by Chinese Center for Disease Control and Prevention. Contents of the questionnaire would include: history of contact with SARS patient, route of infection, methods used for protection and so on.
RESULTS(1) Distribution os SARS patients were confined to 3 wards: 4, 5, and 6 on the 7, 8, 12, 13 and 14 floors in the west unit of the inpatient building. Most of the inpatients were elderly and having severe original diseases. (2) Index patients were the first generation source of transmission and they infected inpatients and medical staff, making them the second generation. People with latent infection who had close contact with SARS patients might also serve as the possible source of transmission. (3) The major transmission routes were: near distant droplet infection and close contact infection. There was also a clue to the probability of aerosol or droplet nuclei infection through air-conditioning and ventilation system.
CONCLUSIONNosocomial infection appeared to be the main characteristic of the SARS epidemic in the early stage of this hospital. Other than close contact and near space airborne transmission of SARS virus, the possibility of long-distance aerosol transmission called for further epidemiological and experimental studies in the future.

OBJECTIVETo prospectively study the relationship between risk factors and stroke incidence and mortality in the Chinese elderly.
METHODSAn analytic study in a cohort population of 1,268 male retired cadres in a military setting. A health-screening program was carried out for all cadres aged 55 years or older in Xi'an in February 1987. Baseline data on smoking, cholesterol, triglyceride, blood pressure, body mass index (BMI), histories of hypertension, hyperlipidemia and coronary heart disease (CHD), stroke, diabetes and family histories of cardiovascular disease were investigated. Main outcome measures were stroke incidence, stroke and all-cause mortality.
RESULTSThe cohort was followed up until June 30, 2001 and a total number of follow-up person-year was 15,546. During the follow-up period, there were 113 new stroke cases identified and the adjusted incidence was 727 per 100,000 person-year. Forty-five deaths were due to stroke and the adjusted mortality was 289 per 100,000 person-year. Using Cox model analysis, after adjustment on age, total cholesterol, triglyceride, smoking, drinking and physical exercise, we noticed that the systolic pressure, BMI, history of CHD and hyperlipidemia were independent risk factors for stroke incidence and morality.
CONCLUSIONThe incidence and mortality of stroke in this cohort were lower than those in the same age group of general population. Monitoring and controlling body mass index and blood pressure level seemed to be important factors for the prevention of stroke in the elderly.
