Cancer immunotherapy is a new approach to cancer treatment. Dendritic cells, the most potent antigen-presenting cells found in humans, have attracted a lot of researches. However, dendritic cells are insufficient to cross-present self-antigens in-vivo. To improve the dendritic cells' antigen-presenting capabilities and the anti-tumor effect, in vitro preparation of dendritic cell vaccine and combination with pro-apoptotic treatments such as chemotherapy are being used.

Objective To compare the advantages and disadvantages between the Mammotome ( MMT ) and conventional resection operation in the diagnosis and treatment of breast tumors . Methods A total of 288 patients during the period from February to July of 2014 were divided into MMT group ( 137 cases ) and control group ( 151 cases ) according to patient ’ s willingness .The surgical and post-operative results , postoperative complications and burden of disease were compared between the two groups . Results As compared to the control group, the MMT group had shorter operation time [(28.3 ±9.1) min vs.(37.5 ±14.2) min, t =-6.472, P=0.000], larger amount of tissue cut [(29.2 ±8.1) g vs.(16.5 ±7.9) g, t=13.462, P=0.000], lower visual analogue scales at one day after surgery [(4.2 ±3.6) points vs.(4.9 ±1.5) points, t=-2.189, P=0.029], lower incidence of postoperative breast shape change [10.2% (14/137) vs.55.0% (83/151), χ2 =64.392, P =0.000], and higher patient satisfaction scores [(7.2 ±1.8) points vs.(5.3 ±2.9) points, t=6.601, P=0.000], but more intraoperative bleeding [(22.3 ± 4.3) ml vs.(12.6 ±5.9) ml, t=15.807, P=0.000], higher incidence of postoperative breast hematoma [9.5% (13/137) vs. 2.6%(4/151),χ2 =6.050, P=0.014], and higher total costs [(5.12 ±1.97) ×103 yuan vs.(3.18 ±2.01) ×103 yuan, t=8.258, P=0.000]. Conclusion The MMT operation has advantages of short time , more cut tissue volume, mild postoperative pain, good postoperative breast shape , and high patient satisfaction , but disadvantages of easy development of hematoma and high total costs.

Objective To observe feature of clinic and imageology in patients with unstable angina pectoris after radiation therapy to chest. Methods The study enrolled 58 patients who had unstable angina pectoris. Twenty-eight patients were in the postradiation therapy to chest group, 30 patients were in the common unstable angina pectoris group. All patients underwent multislice spiral CT(MSCT) examination and coronary angiography (CAG). After one year follow-up, the levels of brain natriuretic peptide (BNP) and ventricular wall motion score index (WMSI) were measured , the incidence of cardiovascular events were observed in all patients. Results Calcific, multi-vessel, thrombotic disease and dissection were significantly different between the two groups, when one year follow-up , the levels of BNP were higher in the postradiation therapy to chest group than those in the common unstable angina pectoris group [ (234.31 ± 121.39) ng/L vs (124.74 ±37.81) ng/L] WMST, incidence of the first heart failure, angina pectoris recurrence and revascularization were significantly different too (P< 0.05 ). Conclusions The complex lesions are major in the postradiation therapy to chest. Moreover, because radiation injures the heart valves and myocardium,these patients' long-term prognosis are worst.

Objective To study the changes of T-C of apolipoprotein CⅢ (ApoCⅢ)-455C gene and to de-tect the relationship between essential hypertension (EH) and the quantity of ApoCⅢ-455C gene. Methods 606 subjects were divided into hypertension group(n=306) and non-hypertension group(n=300). And the two groups 606 were divided into subgroup A (n=90) who had hypertension companied with hypertriglyceridem, subgroup B (n=216)who had hypertension only, subgroup C (n=51) who had hypertriglyceridem only and subgroup D (n= 249) who had none of the two diseases, by the concentration of triglycerides (TG) (TG≥1.69 mmol/L). The quan-tity of ApoCⅢ-455 C was detected by Real Time PCR. TC, TG, HDL-C, LDL-C, ApeA, ApoB 100, ApoCⅢ, ApoE, blood glucose,plasma insulin and waist circumference were measured in all cases. Results There was no difference in the quantity of ApoCⅢ-455C gene between group B and the group D [(45.16±5.97) vs (46.21±6.13)] (P>0.05). The concentration of ApoCⅢ, ApoB100 and the quantity of ApoCⅢ-455C gene in group A were higher than those in group B [0.14±0.03]g/L, (95.00±15.69)g/L, (28.13±4.11) vs (0.09±0.03)g/L,(81.22± 11.87)g/L,(45.16±5.97)(P<0.01)]. It was similar in ApoE [(0.05±0.01) g/L vs (0.04±0.01)g/L] and LDL-C [(2.54±0.61)mmol/L vs (2.15±0.41)mmol/L] (P<0.05). Conclusions The quantity of ApoC Ⅲ-455C gene is not related to EH.

0.05).Conclusion:All the results of the five measurement methods showed that the condyle was located in the center of the fossa with a variation in the healthy adults in intercuspal position.The CBCT image of the sagittal middle layer of the joint could show the joint space accurately and has an important value in the research related to the changes of TMJ space.

OBJECTIVETo investigate the dangerous anastomasis between the external carotid artery and the intracranial arteries.

METHODSAngiograms of the external carotid artery in 250 cases were analyzed, including 35 cases of moyamoya and 215 cases of head and neck lesions.

RESULTSThe 35 cases of moyamoya, 14 middle meningeal arteries (MMA) were found to participate in the blood supply of the brain. In addition, 11 superficial temporal arteries and 7 occipital arteries supplied the brain. All the cases with ligated external carotid artery (ECA) had the pharyngo-occipital anastomasis. Moreover, the ophthalmic arteries in three cases were found to originate from the MMA.

CONCLUSIONSThe external carotid artery has a variety of anastomasis with the internal carotid artery (ICA) and the vertebral artery. Under such circumstances, special measures must be taken to circumvent inadvertent intracranial embolization.

Objective To evaluate the relationship between neoadjuvant chemotherapy (combination of taxanes and anthracyclines ) induced-neutropenia and the efficacy of neoadjuvant chemotherapy and long-term survival in operable breast cancer patients. Methods Two hundred and eleven patients received 4 cycles of neoadjuvant chemotherapy (combination of taxanes and anthracyclines).Clinicopathological characteristics were compared between patients with neoadjuvant chemotherapy-induced neutropenia and patients without neutropenia. The efficacy of neoadjuvant chemotheray and long-term survival rate were analyzed. Results Among 211 patients there were 51 (24. 2% ) cases suffering from neutropenia and 160 (75.8%) cases were of no-neutropenia. The response to chemotherapy in patients with neutropenia were more effective than in no- neutropenia ones ( P ＜ 0. 05 ). The 5-year disease-free survival (DFS) in patients with neutropenia was 82. 4%, while the 5-year disease-free survival ( DFS) with nonneutropenia was 60% ( P ＜ 0. 01 ). Additionally, the 5-year overall survival ( OS ) in patients with neutropenia was 90. 2% and in patients with non-neutropenia patients was 67. 5% ( P ＜ 0. 01 ).Conclusions Chemotherapy-induced neutropenia during neoadjuvant chemotherapy combination of taxanes and anthracyclines in patients with operable breast cancer has a better prognosis. The sensitivity of tumors given to chemotherapeutic drugs could be evaluated by chemotherapy-induced neutropenia.

Objective To investigate the effects of a new c-Met inhibitor SU11274 on apoptosis and motility of c-Met-positive basal-like breast cancer cells MDA-MB-231. Methods The concentrations of SUl1274 were set to 0,0.1,1,10 and 20 μmol/L.Morphological change of apoptotic cells was analyzed by Hoechst33342,MitroTrackerRed and Yo-pro-1 staining.The apoptotic rate of MDA-MB-231 cells were determined by Annexin V/PI double-staining. The expression of apoptosis related proteins (Bcl-XL,Caspase-3 and PARP) and phosphorylation levels of c-Met and Akt were analyzed by Western blot.The capability of motility were measured by wound-healing assay and chemotaxis assay. Results After treatment by SU11274( 10 μmol/L) for 48 h,shrinking apoptotic cells of MDA-MB-231 was observed by flurescent microscope and nuclear fragmentation was seen.Annexin V/PI double-staining showed SU11274induced apoptosis of MDA-MB-231 cells (P ＜ 0.05 ),and the apoptotic rates were (7.3 ± 0.9) ％,( 14.1 ±0.6) ％,(35.5 ± 4.4) ％ and (48.2 ± 5.3 ) ％,respectively.SU11274 downregulated the expression of Bcl-XL and promoted the dissection of Caspase-3 and PARP in a dose dependent relationship.SU11274 prolongs the wound-healing time,decreases the migration cell count (P ＜ 0.05 ) and effectively inhibits the phosphorylation of c-Met and its downstream key proteins Akt in a dose-dependent manner.Conclusions C-Met inhibitor SU11274 induces apoptosis and inhibits the motility of c-Met-positive basallike breast cancer cell line MDA-MB-231,probably through inhibiting phosphorylation of c-Met/PI3K/Akt.

Objective To observe the influence of insulin therapy on the short-term prognosis of patients with acute ST-elevation myocardial infarction (ASTEMI) complicated with hyperglycaemia.Methods A total of 128 patients with ASTEMI complicated with hyperglycaemia were randomized into 2 groups:treatment group and control group.There were 64 patients(50.0％ )in the treatment group and 64 patients(50.0％ ) in the control group.All of the patients were given anticoagulants,antiplatelet drugs,statins,beta-receptor blockers,nitrates and angiotensin-converting enzyme inhibitors (ACEI)or angiotensin receptor blocker (ARB) Moreover,the patients in the treatment group were given extra 50 U insulin ( Novolin R) in 50 ml saline by venous infusion.In the treatment group,Venous blood samples were obtained before and 7 days after treatment to determine the fasting blood glucose and hs-CRP in serum; the levels of fasting blood glucose and hs-CRP and short-term prognosis were compared between the 2 groups.ResultsThe levels of fasting blood glucose in the treatment group were decreased significantly after treatment ( [ 5.4 ± 0.8 ] mmol/L vs [ 11.6 ± 2.3 ] mmol/L,P ＜0.01),but there was no significant change in the control group( [ 10.7 ± 2.1 ] mmol/L vs [ 11.2 ± 2.7]mmol/L,P ＞ 0.05 ).The levels of hs-CRP in both groups were decreased significantly after treatment (P ＜0.05),but it was much more obvious in the treatment group( [ 6.2 ± 1.5 ] mg/L vs [ 8.7 ± 1.8 ] mg/L,P ＜0.05).The incidence of major adverse cardiac events(MACE) during a 3 months′ follow-up in the treatment group was significantly lower than that in the control group ( 12.50％ vs 34.38％,P ＜ 0.05 ).Conclusion Insulin therapy can improve the short-term prognosis in patients with ASTEMI complicated with hyperglycaemia.

Objective To study the effect of macrophage, its stimulating factor, granulocyte macrophage colony-stimulating factor (GM-CSF), the combination of GM-CSF and macrophage on the survival of rat deep epigastric perforator flap (DEP). Methods The stable animal model of DEP flap in Sprague-Dawley rat mimicing human deep inferior epigastric perforator flap in breast reconstruction was established. The rats were treated with subcutaneous injection of recombined rat GM-CSF or rat peritoneal macrophages, respectively, or combination of GM-CSF/ Macrophages. Normal saline was used as parallel negative control. The rats were sacrificed and flap specimens were harvested on day 7 after operation, the flaps survival area were measured by the method of rubbings and the survival proportion of flaps were calculated, Von Will brand factor were detected by immunohistochemistry and microvessel density (MVD), and were calculated with microscopic study, and collagen were stained and quantified by Masson staining. Results Survival proportion of flaps in group GM-CSF (53.08% ± 8. 76% ) was not different with that in macrophages group (47. 95% ± 4. 92% ), and both of these two groups were significantly higher than parallel negative control group (43.28% ± 5.27% ) but significantly lower than combination GM-CSF/ macrophages group ( 61.68% ± 6. 60% ). For MVD, flap in GM-CSF group ( 24. 82 ± 4. 18 ) was not significantly different with macrophages group (24.30 ± 3.02 ), and both of these two groups were significantly higher than group parallel negative control (21.37 ± 2.65 ) but significantly lower than combination GM-CSF/macrophages group ( 29. 82 ± 4. 74). Collagen deposition in the flaps in GM-CSF group (17. 25% ± 2. 85% ) were significantly higher than parallel negative control group (14.41% ± 2. 89% ), macrophages group ( 12. 69% ± 3.55% ) were lower than parallel negative control group but there was no significant difference. That in combination GM-CSF/macrophages group (20.31% ± 3.01% )was significantly higher than GM-CSF group ( P < 0. 05 ). Conclusion Treatment with rat GM-CSF or macrophage can significantly promote the survival of the flaps. Combined application of GM-CSF and macrophage could synergetically promote the survival of the flaps, the vasculogenesis and the collagen deposition.
