ObjectiveTo assess the relationship between central obesity and metabolic syndrome (MS) in community population.MethodsOne thousand and fifty-three individuals aged≥18 (mean,45.6),including 542 men and 511 women,were recruited for questionnaire survey and medical exarmnation from 4 communities of Hangzhou during March and November 2007.Their blood pressure,waist circumference,serum glucose,lipid profile,and other biochemical markers were measured.All data were used for variance analysis.ResultsThe prevalence of MS,central obesity,hypertension,and diabetes mellitus (DM) was 11.2%,23.6%,30.5%,and 8.5%,respectlvely.The prevalence of MS,DM,and hypertension was increased with waist circumference(P<0.05).Waist circumference was positively correlated to body mass index (BMI).systolic blood pressure(SBP),diastolic blood pressure(DSP),fasting blood sugar,total cholesterol,and triglyceride (r=0.812,0.649,0.712,0.657,0.598,and 0.676,respectively),although negativelv with high-density lipoprotein cholesterol(r=-0.578).Waist circumference also showed positive rclationship with the number of lipid metabolism abnormity(r=0.658,P<0.01).CondusionFor Hangzhou community population.central obesity might be one of the risk factors of MS.

Objective To probe into the clinical features, ways of diagnosis and treatment measures of concurrent paratyphoid fever A after renal transplantation. Methods The 5 patients were all town or village people under the county level. After the operation, the immunosuppressive scheme of ciclosporin A (or Tacrolimus) + mycophenolate mofetil (MMF) + prednisone acetate was adopted. One case was caused by catching cold and the rest 4 had no any distinct inducement. Five patients fell ill respectively at the 5th, 7th, 7th, 9th and 14th month after the operation. On the admission, the 5 patients suffered from gastrointestinal symptoms such as vomiting and diarrhea to varying degrees; 3 from toxic symptoms such as fever, intolerance of cold, hypodynamia and headache; 3 from symptoms of the respiratory system such as stuffy nose and congestion of throat; 1 from elevation of blood pressure; 1 from relative slow pulse. In 3 patients with decrease of urine volume, 1 suffered from gross hematuria, swelling of transplanted area of the kidney, pain on pressure and rise of blood pressure. Only 1 patient's paratyphoid fever A antibody in the Widal's test gastroenteritis or untoward reaction of MMF and the curative effect was bad. After definite diagnoses,the combined treatment of the third-generation cephalosporin and FQNS were given to all of them.After treatment for 7-10 days, the symptoms in all patients all disappeared. During the treatment, 1 patient was diagnosed as acute rejection and given the methylprednisolone shock for 3 days. After that, the patient's graft function was improved; 3 patients suffered from relatively great fluctuation of blood concentration of immunosuppressive agent and toxic symptoms such as decrease of the graft function, etc. After adjustment of dosage, their indicators of renal function became normal. Conclusion Early symptoms and accessory examinations of paratyphoid fever A after renal transplantation lack specificities. Diagnosis of paratyphoid fever A after renal transplantation mainly depends on blood culture. Drugs of first choice include FQNS and the third-generation cephalosporin. During the treatment, the doctor should closely monitor blood concentration of the immunosuppressive agent.

ABSTRACT:Objective To assess the effect of prolonged laparoscopic surgery on peritoneal mesothelial cells and fibrinolysis in humans.Methods We examined prospectively 1 6 consecutive patients who underwent laparoscopic surgery (LAP)and 2 1 patients who underwent conventional open surgery (OP)for high-medium rectal cancer with curative intent.During the procedure,biopsy of the parietal peritoneum was made before operation and at 45 min,90 min,and 120 min after operation.The tissue-type plasminogen activator (tPA)and plasminogen activator inhibitor-1 (PAI-1 )were determined by enzyme-linked immunosorbent assay in peritoneal tissues.The cellular injury was detected by LDH assay.The proliferation was quantified by MTT assay.Results PAI-1 activity in the peritoneal tissue was significantly lower in LAP group than in the OP group.tPA activity decreased after 45min of open surgery,but there was no significant change in the LAP group.With time extension,the LDH activity increased and the proliferation of the mesothelial cells decreased.Conclusion Preservation of a prolonged hypofibrinolytic state by inhibition of PAI-1 up-regulation during LAP may predispose patients to less postoperative peritoneal adhesion. The cellular injury becomes apparent and the proliferation is inhibited during prolonged laparoscopic surgery.

Objective To investigate the duodenum absorptive character of monosialotetrahexosylganglioside sodium (GM1) in rats.Methods The contents of phenolsulfonphthalein (as indicators) and GM1 were determined with ultraviolet-visible (UV) method and high performance liquid chromatography (HPLC) method in rats with in situ cycle intestinal perfusion model.Results The ratio of duodenum absorption of GM1 was 10％ in 2 h after cycle and 22％ in 6 h after cycle,respectively.The Ka was (0.030± 0.012)h,and absorption t1/2 was (25.50 ± 8.56)h in 8 h after cycle.Conclusions GM1 is absorption in rat duodenum,and the accumulate absorption of GM1 is almost linearly related to the cycle time.The absorption dynamics of GM1 may be first-order kinetic process.
