Primary intestinal lymphangiectasia is a rare disease, which is characterized by the obstruction of lymphatic return, dilated lymphatics and distorted structure of villi. Lymph fluid leaks into the small bowel lumen as a result of the obstruction of lymphatics and elevated pressure of lymphatics, and leads to malabsorption and loss of proteins. The causes and pathogenesis of PIL are not clear, hut the abnormal immunologic mechanism has got people's attention. Recently, the endoscopic technique has been improved, and the diagnosis rate of PIL has increased obviously. Antisecosis is the basic and effective treatment, especially for children.

Objective To evaluate two regimes of transient intensive insulin therapy in newly diagnosed type 2 diabetic patients with severe hyperglycemia.Methods Sixty-eight newly diagnosed type 2 diabetic patients with fasting plasma glucose(FPG)≥10.0 mmol/L and glycated hemoglobin A1c (HbA1c)≥8.0％were randomized to either cantinuous subcutaneous insulin infusion(CSII)group or multiple daily injection(MDI)group.Glycemic control,daily dose of insulin,body mass index(BMI),the mean area under the insulin curve(AUC),β-cell function(HOMA-β)and insulin resistence(HOMA-IR) were compared before and after treatment.Results There were no significant differences between two groups in days reaching glycemic control and BMI.The maximal insulin dose for glycemic control in CSII group was(0.53±0.06)U·kg-1·d-1 and that in MDI group was(0.71±0.04)U·kg-1·d-1(t= 11.100,P＜0.01).After CSII and MDI treatment,HOMA-β and the mean AUC of insulin were significantly increased(P＜0.01),but there was no significant difference between two groups(P＞0.05).No significant changes in HOMA-IR were observed before and after treatment or between two groups.There were no severe hypoglycemic episodes in two groups and mild hypoglycemic episodes were 0.34％(13/3806)in CSII group and 1.09％(44/4045)in MDI group.Conclusions The excellent glycemic control can be reached by short.terra CSII and MDI treatment in newly diagnosed type 2 diabetic patients with severe hyperglycemia.Lower insulin dose and less mild hypoglycemic episodes seem to be the advantage of CSII regime than MDI regime.β-cell function can be dramatically improved in both therapy regimes.

Objective:To compare the effects of different anesthesia methods on stress hormones and hemodynamic changes in the patients with gynecological laparoscopic surgery. Methods:Retrospective analysis was carried out. Totally 145 patients with gynecolog-ical laparoscopic surgery were divided into two groups according to the anesthesia method, the control group with 72 cases was given routine remifentanyl propofol intravenous anesthesia, and the observation group with 73 cases was given routine propofol isoflurane com-posite anesthesia. Such hemodynamic indices as SBP, DBP and HR, and plasma NE, E, cort and AT II levels at different time points in the two groups were studied and compared, and adverse drug reactions were also observed in the two groups. Results:The BP and HR at T2 and T3 time point in the two groups were significantly lower than those at T0 time point (P<0. 05), and those in the obser-vation group were lower than those in the control group at the same time point(P<0. 05). The levels of NE, E, cort and ATⅡat T2 and T3 time point in the two groups were significantly higher than those at T0 time point (P<0. 05), while the increase in the observa-tion group was lower than that in the control group (P<0. 05). The incidence of adverse drug reactions (ADR), such as respiratory depression, hypertension, bradycardia and so on, and the total incidence of ADR in the observation group were both lower than those in the control group (P<0. 05). Conclusion:Compared with remifentanyl propofol intravenous anesthesia, propofol isoflurane composite anesthesia can keep the hemodynamic stability more effectively and reduce the stress reaction with fewer ADR and promising safety, which is worthy of wider application in clinics.
