Journal of Chinese Physician 2009;11(4):456-457
Objective To study the relationship between serum macrophage migration inhibitory factor (MIF) levels and clinical features in the patients with colorectal cancer. Methods Enzyme-linked immunosorbent assays was used to detect the concentration of MIF in sera of 75 patients with colorectal cancer (35 case with primary colorectal cancer and 40 cases with lymphnode metastasis of colorectal cancer) and 40 healthy controls. The relationship between serum MIF levels and clinical features was analyzed. Results Serum MIF was found to be significantly elevated in the patients with colorectal cancer(mean value 31.2ng/ml) compared with healthy subjects (mean value 13.6ng/ml) (P <0. 001). The levels of MIF in colorectal cancer were significantly correlated with advanced clinical progression pathology stages (P <0. 05) and lymph node metastasis (P < 0. 05). Conclusions Increased expression level of MIF in serum may promote the pathogenesis of colorectal cancer and M1F is closely associated with the stages and lymph node metastasis of colorectal cancer.

Objective To evaluate the value of vascular intervention in the diagnosis and management of hemobilia. Methods With Seldinger's technique ,digital subtraction angiography of superior mesenteric artery and hepatic arteriography were performed on 3 patients with hemobilia, two of whom manifested hemobilia after the operation of liver trauma and one of whom did after the operation of command bile duct stones . Arteriography showed the bleeding vascular branch, the false aneurysm and the arteriovenous fistula. And then a small catheter was put into the bleeding focus. The bleeding branch arteries were selectively embolized with embolus of n-butyl cyanoacrylate (NBCA),PVA granule,spring wire loop and gelatin sponge. Results Two cases showed diffuse bleeding focus and another showed a local bleeding focus. Two cases had expression of false aneurysm and one showed expression of ateriovenous fistula. The artery branches of the bleeding focus were successfully embolizated and the hemobilia stopped immediately. Conclusions Vascular intervention is an effective method for the diagnosis and management of hemobilia.

Objective To characterize the electroanatomical mapping and to assess the value of radiofrequency ablation of atrial tachycardia (AT) in left atria. Methods Nine patients with AT in left atria were studied. Three-dimensional electroanatomical maps were constructed in left atrium using electroanatomical mapping system (Carto). The type of AT (focal or macroreentrant) was identified by the electroanatomical maps, and the ablation targets were at the earliest activation sites or the isthmus of circuit. Results There were ten ATs in 9 cases. The relatively early A waves were recorded in middle, distal or proximal parts of coronary sinus catheter. Nine focal ATs were diagnosed. The activation maps demonstrated that the earliest activation sites were at the ostium of pulmonary veins ( n =5), posterior area of left atrium ( n =2), ostia of left atria appendage ( n =1) or left atria appendage ( n =1) respectively. One macroreeentrant AT was diagnosed, whose circuit propagated through the isthmus, formed by the right superior pulmonary vein and fossa ovalis. Eight focal ATs were all ablated successfully at the earliest activation sites, and one AT from left atria appendage was ablated unsuccessfully. Line of ablation was performed at the isthmus of the macroreentrant AT. During a period of 6-30 months follow-up, one patient with focal AT recurred and underwent another ablation with successful result. No complication occurred. The procedure time and the fluoroscopic time were 90-140 min, 8-16 min respectively in successful cases. Conclusion These results suggest that electroanatomical mapping of AT in left atria may facilitate rapid and accurate identification of the type of AT and guide ablation safely or effectively with less fluoroscopic time and higher success rate, especially in unsuccessful cases with conventional technique.

OBJECTIVE:To explore the effects of dual-phase insulin aspart with different dosing regimens on the related indica-tors of type 2 diabetic (T2DM) patients with poor glycemic control. METHODS:70 T2DM patients with poor glycemic control were randomly divided into group A and group B. All patients were given metformin and stopped other antidiabetic drugs;based on it,group A was additionally given Dual-phase insulin aspart injection,0.5 U/(kg·d),in the morning and evening before a meal by subcutaneous injection;group B was given Dual-phase insulin aspart injection,0.5 U/(kg·d),once before lunch time for 6-10 U and other twice in the morning and evening before a meal by subcutaneous injection. Both groups were treated for 12 weeks. Glu-cose control rate,glucose control time,and glucose indicators,daily fluctuations of glucose before and after treatment and incidenc-es of hypoglycemia and adverse reactions in 2 groups were observed. RESULTS:Glucose control rate in group B was significantly higher than group A,glucose control time was significantly shorter than group A,incidence of hypoglycemia was significantly low-er than group A(P<0.05). After treatment,glucose indicators and daily fluctuations of glucose in 2 groups were significantly lower than before,and group B was lower than group A(P<0.05). There were no obvious adverse reactions during treatment. CONCLU-SIONS:Conpared with 2 times a day,Dual-phase insulin aspart with 3 times a day for administration can effectively improve the glucose control rate and glucose levels in the treatment of T2DM patients with poor glycemic control,with good safety.
