RESUMO
<p><b>OBJECTIVE</b>To evaluate the value of D2+ lymph node dissection for patients with distal advanced gastric cancer.</p><p><b>METHODS</b>Clinicopathological data of 305 cases with distal advanced gastric cancer receiving D2+(n=68) or D2(n=237) lymph node dissection in the Tianjin Cancer Hospital from January 2003 to December 2007 were analyzed retrospectively. The overall 5-year survival rate between the 2 groups.</p><p><b>RESULTS</b>The median survival was 36 months and the 5-year overall survival rate was 40.3% in all patients. The 5-year overall survival rates in the D2+ and D2 groups were 50.4% and 37.4% respectively, and the difference was statistically significant(P=0.049). In multivariate prognostic analysis however, the extent of lymph node dissection was not identified as an independent prognostic factor(P=0.174). Subgroup analysis showed that 5-year survival rate of D2+ group was significantly higher as compared to D2 group for the following subgroups: maximum diameter of tumor larger than 4 cm(43.9% vs. 27.0%), Borrmann type III(-IIII((55.5% vs. 30.1%), poorly differentiated and undifferentiated tumor (49.8% vs. 37.0%), T4 stage (47.8% vs. 31.0%), N2 stage (53.3% vs. 13.9%), N3 stage (20.0% vs. 9.6%) and positive No.6 lymph nodes (33.1% vs. 16.0%).</p><p><b>CONCLUSION</b>Compared with D2 lymph node dissection, D2+ lymph node dissection may benefit some patients with large, poorly differentiated, or late-stage tumor.</p>

Objective To investigate the clinical efficacy of neoadjuvant chemotherapy regimens of TA or AC in the treatment of locally advanced triple negative breast cancer. Methods Data of 99 women with stageⅡ/ Ⅲ locally advanced triple negative breast cancer treated in the Centre Hospital of Cangzhou from Jan. 2006 to Dec. 2011 were retrospectively analyzed. These patients were divided into two groups based on the regimen of the neoadjuvant chemotherapy. Fifty-two cases were received TA regimen(Docetaxel 75 mg/ m2 and pirarubicin 50 mg/ m2 )and 47 cases were received AC( pirarubicin 50 mg/ m2 ,cyclophosphamide 600 mg/ m2 ). IV drip infusion was administered in both groups for 4 cycles before surgery,with 3 weeks for each cycle. The efficacy after treatment,the 2 year recurrence rate and overall survival rate after operation were compared between the two groups. Results The response rates in TA group were 88. 46% ,higher than that of AC group(57. 45% ),and the difference was statistically significant(χ2 = 12. 260,P < 0. 001). Furthermore,the rate of pathological grade 4 and 5 in TA group were 42. 3%(22 / 52)was superior to AC group(23. 4%(11 / 47);P = 0. 046). The 2-year recurrence rate and survival rate in TA group were 23. 08%(12 / 52)and 84. 62% ,as same as that in AC group ((27. 66%(13 / 47)and 80. 85% ;χ2 = 0. 400;P = 0. 53). Conclusion TA and AC are both effective in terms of females with stage Ⅱ/ Ⅲ locally advanced triple negative breast cancer treat with neoadjuvant chemotherapy. Moreover,TA is superior to AC. However,there is no statistical difference of 2-years recurrence rate and survival rate between two groups.
RESUMO
Objective To investigate the effect of gastrointestinal Roux-en-Y gastric bypass surgery on blood sugar and insulin function of patients with type-2 diabetes mellitus.Methods Twenty-seven cases of gastric cancer patients with type-2 diabetes and undergone Roux-en-Y bypass the gastrointestinal treatment in the centre hospital of Cangzhou were selected as our subject.Body mass index (BMI),Glycosylated hemoglobin (HBA1c),Fasting and glucose (FPG),fasting insulin (FINS),Fasting C-peptide (FCP) levels were measured.Glucose (2 hPG),insulin (2 hINS) and C-peptide (2 hCP) levels were detected after 2 h for oral use 75 g glucose.Homeostasis model was applied to assess insulin resistance index (HOMA-IR).Results No significant change was seen in terms of BMI between before and after surgery.Compared to before surgery,the levels of FPG((7.58 ±0.84) mmol/L),2 hPG((10.43 ± 1.88) mmol/L),HbA1c((7.56 ± 1.15)%) and HOMA-IR(4.55 ±0.76) were lower in patients at 3 months after surgery ((9.93 ± 1.57) mtmol/L,(13.89± 2.13) mtmol/L,(9.88 ± 1.66) %,(4.55 ± 0.76),respectively,P < 0.05 or P < 0.01).FPG ((6.56± 0.80) mmol/L),2 hPG ((8.57 ± 1.32) mmol/L),HbA1 c ((6.37 ± 1.24) %),HOMA-IR (4.03 ± 0.45)of patients after 6 months were lower than that of before surgery and 3 months after surgery (P < 0.05 or P<0.01).However,the levels of FINS ((13.67 ± 1.96) mU/L),FCP((2.62 ±0.87) μg/L),2 hINS((49.91± 5.14) mU/L) and 2 hCP ((6.28 ± 1.65) μg/L) were higher in patients with 3 months after surgery compared to that of before surgery ((11.08 ± 1.69) mU/L,(1.78 ± 0.61) μg/L,(36.05 ± 4.03) mU/L,(4.28 ± 1.48) μg/L,P < 0.01).Meanwhile those indices after 6 months (FINS:(15.88 ± 2.05) mU/L,FCP:(3.30 ±0.68) μg/L,2 hINS:(67.40 ±5.68) mU/L,2 hCP:(9.39 ± 1.52) μg/L) were higher than that of before surgery and 3 months after surgery(P < 0.01).Conclusion Roux-en-Y gastrointestinal bypass can effectively reduce blood sugar level and improve the situation of Pancreatic Beta-cell function of gastric cancer patients with type-2 diabetes.
RESUMO
Objective To explore metabolic characteristics of and risk factors for newly diagnosed type 2 diabetes mellitus(T2DM) combined with non-alcoholic fatty liver disease (NAFLD).Methods One hundred and forty-two cases of newly diagnosed T2DM were divided into two groups according to whether they have comorbid NAFLD:group A (without NAFLD,n =79) and group B (combined with NAFLD,n =63).Data collected included body height,body weight,blood pressure,fasting plasma glucose (FPG),blood lipid,serum uric acid (UA),HbA1c and fasting insulin,body mass index and insulin resistance index with homeostasis model(HOMA-IR) were calculated to compare the clinical and biochemical parameters between groups A and B.Results (1) The difference of age and blood pressure between groups A and B were not statistical different (P > 0.05).Compared with group A,BMI ((26.79 ± 1.93) kg/m2 vs (24.61 ± 2.46) kg/m2,t =5.76),FINS((15.49±2.44) mU/L vs (13.20±2.17) mU/L),t =5.91),HOMA-IR((6.74± 1.32) vs (5.65 ±1.10),t =5.37),glycerin trimyristate (TG) ((2.94 ± 0.65) mmol/L vs (1.74 ± 0.46) mmol/L),t =12.86),low density lipoprotein cholesterin (LDL-C) ((3.46 ±0.73) mmol/L vs (2.78 ±0.86) mmol/L,t =5.07) and UA((342.41 ±71.49) mmol/L vs (312.98 ±66.24) mmol/L,t =2.54) were significantly higherand hight density lipoprotein cholesterin (HDL-C) ((0.99 ± 0.17) mmol/L vs (1.21 ± 0.29) mmol/L,t =5.33) was significantly lower in group B (P < 0.05).(2) Using whether to combined with NAFLD as dependent variable,and BMI,FINS,HOMA-IR,TG,LDL-C,HDL-C and UA as independent variable,logistics regression analysis showed that BMI,HOMA-IR and TG were risk factors for NAFLD(OR =2.838,19.241,and 2.019 respectively,P < 0.05).Conclusion Newly diagnosed type 2 diabetes mellitus combined with NAFLD have more obvious dyslipidemia and insulin resistance.Obesity,insulin resistance,hyper-triglyceridemia are risk factors for newly diagnosed type 2 diabetes mellitus combined with NAFLD.
