Objective To examine the effect of carbon dioxide pneumoperitoneum on local pancreas pathological changes, serum levels of amylase, IL-6, E-selectin and P-selectin in rats with severe acute pancreatitis (SAP). Methods Fifty healthy male SD rats were randomly divided into 3 groups: CO2 experiment group ( n =20): SAP was induced by injecting 5% sodium taurocholate through retrogradely common biliopancreatic ducts via duodenal papilla,and then CO2 pneumoperitoneum was established at a pressure of 12 mmHg for 30 min; SAP group ( n = 20): The rats were treated as same as CO2 experiment group, excepting CO2 pneumoperitoneum; Control group (n = 10): Abdomen was incised and nothing was done to duodenum and pancreas except for moving them softly. The blood samples were gathered for examining serum levels of amylase, IL-6, E-selectin and P-selectin, and histopathologic examination of pancreas was done.Results Compared with control group, the pancreatic pathologic histology score, serum levels of amylase,IL-6, E-selectin and P-selectin were significantly higher in the CO2 experiment group and SAP group (P =0.000). The levels of IL-6 were significantly lower in CO2 experiment group compared to SAP group (P =0. 000). There was no significant difference between CO2 experiment group and SAP group in pancreatic pathologic histology score( P =- 0.294), the levels of serum amylase ( P = 0.073 ), E-selectin and P-selectin. Conclusions CO2 pneumoperitoneum has no adverse effect on the changes of pathological histopathology and the levels of IL-6, E-selectin and P-selectin in SD rats with SAP.

Objective To investigate gene mutations of the epidermal growth factor receptor of tumor tissue and peripheral blood in non-small-cell lung cancer, and to compare the consistency of EGFR mutations in tumor tissue and peripheral blood, fluorescence quantitive polymerase chain reaction (FQ-PCR) was performed according to standard procedure. Methods 112 peripheral blood and 87 tumor tissue of NSCLC were detected by FQ-PCR, among which 45 cases were analyzed using peripheral blood-tumor tissue matched samples. The relationship between clinical efficacy and EGFR mutations Was analyzed. Results Our results showed that there is 32 mutations in EGFR in 112(28.6%)of the patients'peripheral blood samples and 27 mutations in EGFR in 87(31.O%)tumor tissue. EGFR mutations were mainly found in adenocarcinoma and non-smokers in NSCLC (P<0.05). The consistency of EGFR mutation between tumor tissue and peripheal blood reached 71.4%. The clinical outcome of mutations Was significantly effective(P

Objective To investigate the relationship between serum adipocyte fatty acid binding protein (FABP4),insulin resistance and maternal complications in patients with gestational diabetes mellitus (GDM) with satisfactory glucose control.Methods 60 cases of pregnancy between 24 and 28 weeks of OGTT diagnosed GDM pregnant women were selected.30 cases with satisfactory blood sugar control were selected as satisfactory blood sugar control group,30 cases with unsatisfied blood sugar control were selected as unsatisfied blood glucose control group.Healthy control group was selected from 24 to 28 weeks of healthy pregnancy in 30 patients.Fasting serum FABP4,fasting blood glucose(FPG) and fasting insulin(FINS) were measured in three groups of pregnant women after 24 to 28 weeks and pregnant term.To calculate the insulin resistance index (HOMA-IR) of the steady state model,and record and observe the complications of the three groups.Results In the satisfactory blood glucose control group,the incidence rates of pregnant hypertensive disorders,excessive amniotic fluid,premature rupture of membranes,postpartum hemorrhage,cesarean section,macrosomia,neonatal asphyxia,neonatal hypoglycemia,hyperbilirubinemia of newborn were 10.0％,6.7％,13.3％,6.7％,23.3％,16.7％,10.0％,16.7％,10.0％,which were significantly lower than those in the unsatisfied blood glucose control group (23.3％,20.0％,23.3％,16.7％,33.3％,33.3％,20.0％,30.0％,36.7％),the two groups had significant differences(x2 =4.33,6.12,6.01,3.97,7.41,5.46,10.02,4.79,9.22,all P ＜ 0.05).The incidence rates of pregnant hypertensive disorders,excessive amniotic fluid,macrosomia between the satisfactory blood glucose control group (10.0％,6.7％,16.7％) and healthy control group(3.3％,0.0％,6.7％) had statistically significant differences (x2 =7.45,8.46,4.69,all P ＜ 0.05).The incidence rates of postpartum hemorrhage,premature rupture of membranes,cesarean section,neonatal asphyxia,neonatal hypoglycemia,neonatal hyperbilirubinemia between the satisfactory blood glucose control group (6.7％,13.3％,23.3％,10.0％,16.7％,10.0％) and healthy control group(10.0％,10.0％,20.0％,6.7％,13.3％,3.3％) had no statistically significant differences (all P ＞ 0.05).Pregnant 24 ～ 28 weeks,FABP4,FINS,FPG and HOMA-IR of the satisfactory blood glucose control group were (1.78 ± 0.33) ng/mL,(12.35 ± 0.48) mIU/L,(5.51 ± 0.96) rmmol/L,(3.88 ± 0.55),which of the unsatisfied blood glucose control group were (2.36 ± 0.08) ng/mL,(13.92 ± 1.17) mIU/L,(5.46 ±0.74)mmol/L,(3.95 ± 1.17),the differences between the two groups were not statistically significant (all P ＞ 0.05),and compared with the healthy control group,the differences were statistically significant(t =15.32,10.36,11.54,7.34,all P ＜ 0.05).After term pregnancy,the FINS,HOMA-IR of the satisfactory blood glucose control group were still higher than those in the healthy control group,the differences were statistically significant(all P ＜ 0.05).However,FABP4,FPG between the satisfactory blood glucose control group and healthy control group had no statistically significant differences (all P ＞ 0.05).Conclusion With the control of blood glucose levels,decreased in patients with GDM FABP4,fasting blood glucose,glycosylated hemoglobin level,but high insulin resistance still persists and glycemic control satisfaction does not completely reduced the occurrence of the complications in both mothers and neonates.

Objective To explore the relationship between type 2 diabetes mellitus(T2DM)and thyroid diseases by analyzing the abnormal status of thyroid hormone and antibodies in T2DM patients and the healthy control group.Methods The serum thyroid stimulating hormone (TSH),free triiodothyronine (FT3),free thyroxine (FT4),anti-thyroglobulin antibody (TGAb)and anti -thyroid peroxidase antibody (TPOAb)were measured in 396 patients with T2DM and 411 healthy persons.Results In the healthy group,the incidence rate of abnormal thyroid hormone was 7.5%,in which the male was 5.5% and female was 9.4%,the incidence rate of subclinical hypothyroidism in females was 4.7%,which was higher than 1.5% in males,there was statistically significant difference between them(P <0.05);the positive rate of TPOAb in the healthy control group was 10.2% and the positive rate of TGAb was 6.6%;in T2DM patients,the incidence rate of thyroid hormone abnormalities was 16.2%,which in males and females were 12.3% and 20.5% respectively,among them the incidence rate of subclinical hypothyroidism in females was 9.2%,which was significantly higher than 4.3% in males,the difference had statistical significance (P <0.01),T2DM patients with subclinical hypo-thyroidism accounted for 40.6% of thyroid dysfunction incidence rate;the positive rate of TPOAb was 15.2% and the positive rate of TGAb was 7.1 %.Conclusion The incidence rate of thyroid diseases in T2DM patients is significantly increased compared with the healthy control group,subclinical hypothyroidism in females is predominant;screening thyroid autoantibodies and monitoring FT3,FT4 and TSH at regular intervals in T2DM have the important clinical significance for evaluating the disease condition,jud-ging prognosis and guiding treatment.

Objective To investigate whether area under the curve (AUC) of oral glucose tolerance test (OGTT) could work as a predictor of outcomes of gestational diabetes mellitus (GDM) on condition that blood glucose is controlled. Methods A total of 1 796 women who had a standard antenatal care in Peking University First Hospital and gave single live births from July 1, 2011 to December 31,2 013 were included.They should be diagnosed of GDM by the diagnosis criteria of gestational diabetes published by the Ministry of Health of PRC and diabetes pre-pregnancy excluded. Data were analyzed with SPSS 17.0, grouping by AUC. Results (1)Women with higher AUC had a rising trend of age and a downward trend of gestational weight gain, however, not statistically significant [specifically, in the four group of less than 15.00 mmol·L-1·h-1, 15.00 to 16.79 mmol · L-1 · h-1, 16.80 to 17.99 mmol · L-1 · h-1 and 18.00 mmol · L-1 · h-1 or more, gestational weight gain was (15.3±5.2), (14.1±4.8), (13.5±4.7) and (13.1±4.8) kg]. The prevalence of macrosomia raised while AUC increased. Those with an AUC of lower than 15.00 (mmol·L-1·h-1) had a lower risk of macrosomia (P=0.04) . But those with an AUC of 18.00 (mmol·L-1·h-1) or more had a higher risk of macrosomia (P=0.02). There was a rising trend in premature birth and preeclampsia with AUC increasing but not significant (the prevalence of premature birth was 4.38%, 5.36%, 7.71%and 7.94%while that of preeclampsia was 2.85%, 4.69%, 4.67% and 5.08% in these four groups).(2)The prevalence of macrosomia was 12.76% (54/423) when overweight pre-pregnancy ,significantly higher compared with 5.87%(65/1 107) in normal group. The prevalence of preeclampsia was 5.91%(25/423) and 3.34%(37/1 107) in those two groups, which was also significantly different. The obese group had a statistically highest prevalence of preeclampsia of 9.23%(12/130). (3)AUC (P<0.05, OR=1.113, 95%CI:1.008-1.218), as well as gestational weight gain (P<0.05, OR=1.520, 95%CI:1.279-1.806) and pre-pregnancy BMI (P<0.05, OR=1.183, 95%CI:1.125-1.243) made a difference in the prevalence of macrosomia. Meanwhile, pre-pregnancy BMI made sense in the prevalence of premature labor (P<0.05, OR=1.059, 95%CI:1.003-1.119) and preeclampsia (P<0.01, OR=1.202, 95%CI:1.123-1.286). Conclusions AUC, as well as pre-pregnancy BMI and gestational weight gain have a significant impact on outcomes of GDM, macrosomia especially, though blood glucose is controlled. Meanwhile, AUC might be considered as a predictor of macrosomia.
