Objective To investigate the risk factors related with postoperative complications following radical gnstrectomy for gastric cancer in cirrhotic patients. Methods In this study, 1474 cases underwent radical gastrectomy for gastric carcinoma in the past six years and the postoperative complications were retrospectively reviewed. The risk factors related with postoperative complications of cirrhotic patients were analyzed by Logistic regressive analysis. Results The postoperative morbidity rates of the 2 groups with or without liver cirrhosis were 51.22% and 23.94% (X2 = 15.955, P<0.01), and the mortality rate was 7.32% and 0.91% (P = 0.009), respectively. The main complications of the group with liver cirrhosis were postoperative aseites (5 cases), hepatic failure (4 cases), wound infection or dehiscence (4 cases), intra-abdominal infection (4 cases), etc, and three patients in the group died from extensive bleeding, jejunal fistula and hepatic failure respectively. Univariate Logistic analysis revealed that age (OR = 1.277, 95% CI:0.991 ~ 1.646), preoperative nscites (OR = 20.900,95% CI: 2.349 - 185.933), the albumin level (OR =0.160,95% CI:0.041 ~ 0.629), Child classification (OR = 9.500,95% CI: 1.046 ~ 86.261), portal hypertension (OR = 4.000,95% CI: 1.057 ~ 15.138), esophageal variees (OR = 4.400,95% CI: 1.095 ~ 17.676), transfusion (OR =3.714,95% CI: 1.021 ~ 13.511) and blood loss (OR = 1.442, 95% CI:1.023 ~ 2.034) were the main factors associated with postoperative complications of the group with liver cirrhosis. Muhivariable Logistic analysis showed that preoperative ascites (OR = 19.213,95% CI: 1.569 ~ 231.255), Child classification (OR = 12.661,95% CI: 0.721 ~ 222.458), esophageal varices (OR =6.008,95% CI:0.857 ~42.097) and blood loss (OR = 1.574,95% (7,1:0.938 ~ 2.640) were the independent risk factors. Conclusion Gastrectomy for gastric carcinoma in cirrhotic patients engenders considerably high postoperative mortality and morbidity. Preoperative ascites, Child classifation, esophageal variees and intraoperative blood loss were factors closely related with postoperative complications.

Objective A previously reported female diagnosed with type A insulin resistance syndrome bearing a heterozygous missense mutation of R1174W in the insulin receptor gene was followed for 7 years since the age of 16 years. Methods Five-hour oral glucose tolerance tests (OGTT) were done on baseline, the 3rd, 6th and 7th year respectively, with serum insulin and C-peptide measured at the same time points. Areas under of curve (AUC) of glucose, insulin and C-peptide were compared between the years.Acute insulin response (AIR) was determined at baseline and the 7th year. The dose response were insulin secretion rates at each time point during OGTT being plotted over the corresponding glucose levels, and the slopes of which quantified the insulin secretion responding to glucose. Results The follow up data showed that the glucose metabolism of the subject did not deteriorate over time with yearly glycosylated hemoglobin A1c (HbAlc) being normal (4.6%-5.5%), and hyperinsulinemic hypoglycemia was a persistent phenomenon observed at 4-5 hours post-load. The fasting and AUCs of serum insulin and C-peptide tended to decline without simultaneously increase of those of plasma glucose. The AIR decreased by 56% as compared to baseline. The dose response curves shifted downward as years went by. Conclusions It supports that with the alleviation of physiological insulin resistance after puberty, the gross hyperinsulinemia tends to ameliorate, and β-cell secretion does not deteriorate over time as glucose homeostasis maintains.

Objective To investigate the current status of type 2 diabetic patients who failed to achieve the glycemic control target, and provide theoretic evidences for making corresponding strategies. Methods The 2 diabetic patients who failed to reach the glycemic target were recruited from 181 hospitals in 26 cities and received a standard questionnaire, the conditions of their blood glucose level, lifestyle intervention, blood sugar monitoring, and drug therapy were recorded. Totally 3 861 questionnaires with complete information were collected. And the causes which account for glycemic control status were analyzed. Results Among these patients, the mean HbA1c was 7.9%, the mean fasting plasma glucose was 8.2 mmol/L, and the mean postprandial plasma glucose was 11.5 mmol/L. Only 25.6% of patients take their diet control strictly as prescribed and 44. 5% of patients have little exercise. 35. 8% and 47.8% of patients did not monitor their fasting and postprandial plasma glucose,respectively. Glycemic control in the patients aged > 60 years was similar to the younger patients, but the hypoglycemia incidence in the elder group reached 35.5%, which was higher than those in the other 2 groups (20.8% and 21.4%, both P<0. 05 ). The proportion of patients with mono-therapy and combination therapy was 46. 1% and 51.7%, while the proportion with combination therapy rose in the patients aged >60 years (58.7%;Compared with the other age-groups, all P<0.05 ). 75 % of patients have adjusted their drug administration regimen since initial treatment. Conclusions Inadequate or inappropriate drug therapy regimen is a major cause responsible for this poor glycemic control status. In addition, the unhealthy life styles, insufficient blood sugar monitoring, and poor compliance were also important causes. Thus, for these patients, it is necessary to further enhance patients' education, to improve life style intervention, as well as to select more effective, safer, and compliant drug therapy regimens. Finally, the glycemic control target for the elder patients should be more flexible.
