Currently adopted surgical approaches of laparoscopic combined organ resection for gastrointestinal cancer include laparoscopic pancreaticoduodenectomy and gastrectomy, laparoscopic gastrectomy combined distal pancreatectomy and splenectomy, laparoscopic gastrectomy and cholecystectomy, laparoscopic rectal anterior resection and total hysterectomy with bilateral salpingo-oophorectomy, and laparescopic colorectal and hepatic metastases resection. Satisfactory clinical outcomes of these procedures for gastrointestinal cancer were obtained in the reported cases. However, the number of cases in current studies on laparoscopic combined organ resection for gastrointestinal cancer was too small and no control groups involved, and multicenter clinical trials were not yet conducted. In conclusion, the future of laparoscopic combined organ resection for gastrointestinal cancer is promising, while its feasibility and safety require further investigation.

Objective To investigate the correlation between stenosis or occlusion of vertebralbasilar artery and the location of infarctions in pontine. Methods All 139 patients with acute pontine infarction who were admitted to the Department of Neurology,Xuanwu Hospital,Beijing,during February,2005 and September,2007 were studied. All patients received the examinations of head MRI and digital subtraction angiography (DSA). Patients with possible cardiac embolism were excluded from the study. All the cases were then divided into four groups: A( paracentral artery group); B (short rotary artery group); C (long rotary artery group) and D (combined group). Results In all 139 cases,78 cases (56. 1% ) were in A group,3 (2. 2% ) in B group,7 (5.0%) in C group and 51 (36.7%) in D group. Fifty-six cases (40. 3% ) have occlusion in vertebral artery,60 cases (43.2%) have stenosis of vertebral artery. Cases having stenosis or occlusion in basilar artery are 14 cases (10. 1% ) each. Sixteen cases (11.5%) have unimpaired vertebral-basilar artery. A group is related to occlusion of vertebral artery and basilar artery and unimpaired artery ( x2 =3. 945,6. 824,4. 485 ,P = 0. 043,0. 021,0. 041 respectively). D group is related to occlusion of basilar artery ( x2 = 10. 952,P = 0. 006). Logistic binary analysis found that A group is more related with occlusion of vertebral artery ( OR = 2. 261 ),while D group is more related to occlusion of basilar artery ( OR = 15. 750). Conclusions There is a significant correlation between stenosis or occlusion of vertebral-basilar artery and the locations of infarctions in pontine. The physicians are suggested to perform the examinations on cerebral vessels such as brain MRI or DSA in patients with infarctions in pontine.

Sentinel lymph node (SLN), the hypothetical first regional lymph node or group of lymph nodes to received lymphatic drainage from a primary tumor, can predict the likelihood of further nodal involvement. SLN mapping was initially applied to the treatment of breast cancer and melanoma, and it also shows gratifying effect on thyroid cancer, pancreatic cancer and gastrointestinal tumors. The development of SLN mapping in colorectal cancer has brought us a new approach to design personalized operation and adjuvant therapy plans. However,various SLN mapping techniques in colorectal cancer available present fluctuant navigation performances, which need to be replaced by an economical, convenient and accurate tracing technique. Hopefully the optimized SLN mapping can play a more important role in the management of increasing occurred early colorectal cancer.

Objective To investigate the risk factors with placental abruption in patients with preeclampsia.Methods Retrospective analysis on medical documents of 219 patients treated in Peking University Third Hospital from Jan.1994 to Dec.2008.Patients were divided into 3 groups, including 52 cases with severe preeclampsia terminated following placental abruption, 130 cases only with severe preeclampsia and 37 cases with unexplained placental abruption without preeclampsia.One hundred and multivariate regression analysis were used to identify the risk factors for placental abruption in patients with preeclampsia.Results (1) When compared with those in control group, univariate analysis showed that gravidity, parity, history of preeclampsia, second and third trimester pregnancy loss, history of autoimmune disease, chronic hypertension disease, lack of regular antenatal care, fetal growth restriction (FGR) and raises of umbilical artery Doppler resistance were risk factors associated with placental abruption.Logistic regression analysis showed that lack of a regular antenatal care ( OR = 45.348, 95% CI: 17.096 - 120.288,P = 0.000 ), FGR ( OR = 27.087, 95% CI: 5.585 - 131.363, P = 0.000 ) and second/third trimester pregnancy loss( OR = 16.068, 95% CI: 1.698 - 152.029, P = 0.015 ) were independent risk factors with placental abruption.(2) When compared with those in preeclampsia patients without placental abruption,the history of preeclampsia ( OR = 3.715,95% CI: 1.096 - 12.596, P = 0.035 ) and lack of a regular antenatal care( OR = 2.509,95% CI:1.173 -5.370,P =0.018) were risk factors for placental abruption in preeclampsia.Conclusion Lack of regular antenatal care, FGR, history of preeclampsia and second/third trimester pregnancy loss were risk factors associated with placental abruption in patients with preeclampsia.

Objective To assess the influence of the wall motion state and the infarct size of myocardial on left atrial(LA) function in patients with myocardial infarction(MI), and to investigate the main determinants of LA function. Methods LA function of the small area of MI group (group A), the large area of MI group (group B) and control.group were compared,and the influence of the infarct size on LA function was evaluated. The correlation between parameters of LA function and wall motion score index (WMSI) was analyzed. Stepwise regression was made to determine the influencing factors of LA function. index (VpreⅠ),LA active emptying volume index (AEVI), LA ejection force index (EFI) of group A and group B were larger than those of control group,and the parameters of group B were also larger than those of group A(P<0.05). LA passive emptying fraction (PEF) and atrial expansion index (AEI) of group A and group B were smaller than those of control group,and the parameters of group B were also smaller than regression equation. Conclusions With the increasing of areas of infarction and the aggravating of wall motion sate,the LA remodeling aggravated. The boost pump function of LA augmented, and the function of conduit and reservoir of LA was reduced. Wall motion state, LV remodeling and LV diastolic function were the major determinants of augmented LA function in MI patients.
