ABSTRACT
Objective To observe the changes of carbohydrate antigen 19-9 (CA19-9) in type 2 diabetes mellitus (T2DM) patients,and determine the positive boundary value of CA19-9 for differentiating digestive tract malignant tumor and T2DM.Methods The clinical data of 300 cases were retrospectively analyzed.The patients were divided into 3 groups:group A with 100 T2DM patients,group B with 80 tumor patients and group C with 120 non-tumor and non-diabetic mellitus normal people.Chemiluminescence was used to determine the serum CA19-9 level,and the results of the 3 groups were analyzed.Results The serum CA 19-9 levels in group A and group B were significantly higher than that in group C [(21.38 ± 18.23),(32.21 ± 19.00) kU/L vs.(11.21 ± 10.08) kU/L],and there were statistical differences (P ＜0.05).Furthermore the serum CA 19-9 level in group B was significantly higher than that in group A,and there was statistical difference (P ＜ 0.05).The serum CA19-9 level was associated with fasting plasma glucose (r =0.527,u =5.144,P ＜ 0.01),2 h postprandial blood glucose (r =0.617,u =6.044,P ＜ 0.01),fasting insulin (r =0.427,u =4.144,P ＜ 0.01),and glycosylated hemoglobin (r =0.507,u =4.881,P ＜ 0.01),while the serum CA19-9 level was not associated with serum creatinine and courses of T2DM.CA19-9 ROC curve was used to determine 45.0 kU/L as the positive boundary value between the group A and group B.Conclusions The serum CA 19-9 level of T2DM patients is higher than that of normal people,but lower than that of patients with digestive tract malignant tumor.The serum CA 19-9 level is associated with blood glucose and glycosylated hemoglobin.The 45.0 kU/L as serum CA19-9 level positive boundary value can significantly improve the diagnosis value of digestive tract malignant tumor.
ABSTRACT
Spillage of cyst contents during surgical operation is the major cause of recurrence after hydatid cyst surgery. Instillation of a scolicidal agent into a hepatic hydatid cyst is the most commonly employed measure to prevent this complication. SB202190 is a pyridinyl imidazole derivative and is known to be a specific inhibitor of p38 MAPK. In the present study, the scolicidal effect of SB202190 was investigated. Freshly isolated Echinococcus granulosus protoscolices were subjected to SB202190 treatment (10, 20, 40, and 80 microM), and the effects on parasite viability were monitored by trypan blue staining. Corresponding effects were visualized by scanning and transmission electron microscopy. Dose-dependent protoscolex death within a few days of SB202190 treatment was observed. Although the in vitro scolicidal effect of SB202190 was satisfactory, the in vivo efficacy of this drug and also possible side effects remain to be further investigated.

Objective To study the efficacy of different anti-adhesion agents used in preventing tubal obstruction after recanalization.Methods Five hundred and eight patients with tubal obstruction were divided into 245 cases in control group,108 cases in chitosan group;113 cases in sodium hyaluronate group and 42 cases in lipiodol group.The patients in control group were injected with anti-inflammation agents after recanalizatian,while other groups were injected with chitosan,sodium hyaluronate or lipiodol at dose of 2-3 ml in every therapeutic group.The rate of location of tubal obstruction and tubal recanalization were recorded during operation.Then patients in every group were followed up on tubal patency after 3 months,and pregnancy rate after 12 months.Results Among 1016 fallopian tubes in 508 patients,there were 330 tubes occlusion at isthmus portion and 563 tubes occlusion at interstitial portion of fallopian tube.Thirtyseven fallopian tubes were ablated because of ectopic pregnancy,86 fallopian tubes were unobstructed.(1)The recanalization rate were 95.7% (179/187) in chitosan group,97.9% (191/195) in sodium hyaluronate group,98.7% (75/76) in lipiodol group and 97.7% (425/435) in control group,which did not show statistical difference (P＞0.05).(2) The rates of tubal patency after 3 months of 91.7% (99/108) in chitosan group and 88.5% (100/113) in sodium hyaluronate group were significantly higher than 71.4% (30/42) in lipiodol group and 74.3% (182/245) in control group (P ＜0.05).(3)The rates of intrauterine pregnancy after 12 months were 48.1% (52/108) in chitosan group and 41.6% (47/113) in sodium hyaluronate group,which were significantly higher than 23.8% (10/42) in lipiodol group and 24.1% (59/245) in control group (P ＜ 0.05).Conclusion Chitosan and sodium hyaluronate could be effective to prevent tubal obstruction after interventional recanalization and increase pregnancy rate.
ABSTRACT
Objective To investigate the effect of lipid ultrasonic microbubble on the cellular absorption rate of antiparallel phosphorothioate triplex-forming oligonucleotide(TFO) and the expression of the tissue factor(TF) in endothelial cells.Methods The GT21-apsTFO,specific to the gene sequence of the shearing stress response element,was synthesized and the lipid ultrasonic microbubble carrying TFO was constructed.The ECV304 cells were divided into 4 groups:control group(SSRE),received shear stress only for 6h;TFO+ ultrasonic irradiation group(TFO+U),treated with 60?l TFO in final concentration of 0.2?mol/L and ultrasonic irradiation for 30s simultaneously;TFO-lipid microbubble group(TFO-M),treated with 60?l lipid microbubble loaded with TFO in final concentration of 0.2?mol/L;and TFO-lipid microbubble + ultrasonic irradiation group(TFO-M+U),treated with 60?l lipid microbubble loaded with TFO(final concentration was 0.2?mol/L) and ultrasonic irradiation for 30s simultaneously.Cells in the last 3 groups were treated with shear stress for 6h with pressure of 1.2Pa 24h after transfection.The fluorescent microscope was used to observe the cellular absorption rate of TFO.The immunofluorescence method and RT-PCR were employed to determine the protein and mRNA expressions of TF.Results The transfection efficiency of the TFO was higher in TFO-M+U group(38.83%?6.52%) than in TFO-M group(9.50%?2.88%) and TFO+U group(12.66%?3.01%,P
ABSTRACT
Objective To evaluate the function of vascular endothelial growth factor (VEGF) and other clinical indexes to forcast ovarian hyperstimulation syndrome (OHSS). Method Collecting the serum and follicular fluid (FF) of 42 cases in the in vitro fertilization and embryo transfer (IVF-ET) cycles and then analysis the relationship of the clinical and detected indexes between the OHSS (10 cases) and the non-OHSS (32 cases). Results The concentration of VEGF in FF?E 2 on the day of human chorionic gonadotropin (hCG) injection, basal luteinizing hormone (LH) and the number of ovum retried much higher in the OHSS than in the non-OHSS. Conclusions The concentration of VEGF in FF of OHSS cases is higher than that of controls, supporting the role of VEGF as a mediator of OHSS. Therefore VEGF in FF is a forcast index of OHSS.
