Objective To explore the changes of plasma melatonin(MT)level in hypoxic-ischemic encephalopathy(HIE)neonates,and elucidate the function of rnelatonin in the pathogenesis and the prognosis of HIE.Methods Fourty HIE neonates were divided into 2 groups,20 mild HIE neonates and 20 moderate or severe HIE ones.The femoral vein blood were collected in 48 h and on 7 d after birth in mild HIE group,and in 48 h,on 7 d and(14±4)d after birth in moderate on severe HIE group.Twenty normal term infants served as control group.The level of plasma MT was determined with enzyme-labeled immunosorbent assay.Results Compared with control group[(8.003±1.840)ng/L],The MT level in mild HIE group in 48 h after birth[(13.311±4.025)ng/L]was higher(P＜0.01),but there was no difference on 7 d[(6.605±1.269)ng/L](P＞0.05);The MT level in moderate or severe HIE group in 48 h after birth[(5.487±1.997)ng/L]was lower(P＜0.01),but it was higher on 7 d[(16.201±5.594)ng/L](P＜0.01),there was no difference on(14±4)d[(6.799±1.765)ng/L](P＞0.05).Conclusion MT may have protective action on HIE.The prognosis of HIE with rising MT level in 48 h after birth is better than that with lower MT level.

Objective: To investigate the mechanism of vascular endothelial growth factor ( VEGF)165 and hepatocyte growth factor (HGF) improving cardiomyocyte proliferation in experimental porcine after myocardial infarction (MI).
Methods: The MI model was established by left anterior descending artery ligation in 15 male pigs and the animals were divided into 3 groups, n=5 in each group. Control group, the pigs received normal saline injection at the infarct and peri-infarct zones. VEGF group, the pigs received (1×1010 ) pfu of viral titers of Ad-VEGF injection. HGF group, the pigs received (1×1010 ) pfu of viral titers of Ad-HGF injection. The myocardial perfusion and cardiac function were examined by SPECT, the protein expressions of VEGF165 and HGF were measured by Western blot analysis, cardiomyocyte proliferation was analyzed by immunolfuorescence and immunoprecipitation method.
Results: ① Compared with Control group, the expressions of VEGF165 and HGF were higher at the infarct and peri-infarct zones in both treatment groups; ② Both treatment groups had better cardiac function and myocardial perfusion; ③ Both treatment groups had improved cardiomyocyte proliferation at the infarct and peri-infarct zones.④VEGF165 promoted cardiomyocyte proliferation via p27 pathway;⑤HGF promoted cardiomyocyte proliferation via p21 and p27 pathways.
Conclusion: VEGF165 and HGF could improve myocardial perfusion and function in experimental porcine after MI, VEGF165 and HGF promote cardiomyocyte proliferation via different pathways.

Objective:This study was conducted to evaluate the roles of internal mammary sentinel lymph node biopsy (IM-SL-NB) in the treatment of breast cancer patients with clinically positive axillary lymph nodes. Methods:This study is a one-armed clini-cal research conducted from June 2013 to October 2014. A total of 64 breast cancer patients from Shandong Cancer Hospital with clini-cally positive axillary lymph nodes were enrolled in the study. All patients underwent axillary lymph node dissection. Meanwhile, IM-SLNB was performed in all patients using the new injection method of radiotracer. Results:Among the 64 enrolled patients, the visual-ization rate of internal mammary lymph node was 59.4%(38/64). For the 38 patients who were subjected to visualization of the internal mammary node, the detection rate was 100%(38/38), and the incidence of complications was 7.9%(3/38). The metastasis rate of inter-nal mammary lymph node was 21.1%(8/38). Patients with upper inner quadrant tumors and metastasis of more axillary lymph nodes had a significantly higher chance of developing sentinel lymph node metastasis (P<0.001 and P=0.017, respectively) than the other pa-tients. The clinical benefit rate of the above mentioned treatment was 59.4%. Among the patients, 12.5%(8/64) received extra internal mammary radiotherapy, whereas 46.9%(30/64) patients avoided the unnecessary internal mammary radiotherapy. Conclusion:IM-SL-NB should be performed in breast cancer patients with clinically positive axillary lymph nodes because IM-SLNB could provide the ac-curate indication of radiation to the internal mammary area, especially for the patients with upper inner quadrant tumors and those with a suspiciously high level of axillary lymph node metastasis.

Background and purpose:Whether axillary sentinel lymph node biopsy (ASLNB) could replace axillary lymph node dissection (ALND) in patients who converted after neoadjuvant chemotherapy (NAC) from cN+ to ycN0 is still contentious, and the previous study only evaluated the pathological status of ALN without internal mammary lymph node (IMLN) condition. This study is to evaluate roles of ASLNB and internal mammary sentinel lymph node biopsy (IM-SLNB) in breast cancer patients after NAC.Methods:From Jan. 2012 to Dec. 2014, 60 breast cancer cT1-4N0-3M0patients who were scheduled for neoadjuvant chemotherapy (NAC) and agreed to accept surgery after NAC from our department were enrolled into the retrospective study. Patients with cN0 before NAC and ycN0 after NAC underwent ASLNB (group A). Patients with cN+ received NAC and ycN0 after NAC (group B) were treated with ASLNB and ALND. Only patients whose clinical nodal status remained positive (ycN+) after NAC underwent ALND without ASLNB (group C). All the patients received radiotracer injection and patients in group A and group B received blue dye injection additionally. Meanwhile, IM-SLNB would be performed for all patients with IM-SLN visualization.Results:The number of patients enrolled in group A, group B and group C was 6, 45 and 9 cases respectively. The accuracy rate of ASLNB in group A was 100% (6/6). Only one patient was axillary sentinel lymph node (ASLN) positive performed ALND. With combination of blue dye and radiolabeled colloid, the accuracy rate of ASLNB in group B was 100% (48/48) and the false negative rate (FNR) was 17.9% (5/28). The FNR in patients with 1, 2 and>2 SLNs examined was 27.3% (3/11), 20.0% (2/10) and 0% (0/7). All of the ALNs were positive in group C. The visualization rate of IM-SLN was 63.3% (38/60). The detection rate of IM-SLNB was 97.4% (37/38) and the metastasis rate was 8.1% (3/37). The incidence of complications was 5.3% (2/38).Conclusion:ASLNB can be performed either before or after preoperative chemotherapy for patients with cN0 disease. Among women with cN+ converted to ycN0 who had 3 or more SLNs examined, the FNR could return to be less than 10%. Those patients whose nodes are still ycN+ should perform ALND. IM-SLNB should be performed routinely in all breast cancer patients after NAC, for it might help to make clear of the nodal staging and the pathological status of IM-SLN and provide the accurate indication of radiation to the internal mammary area in case of under-stage and under-/over-treatment, expecting to develop the deifnition of pathological complete response (pCR).

Objective To explore the clinical variables associated with the shrinkage modes of primary breast tumor in women after neoadj uvant chemotherapy (NAC ), and to develop a nomogram for predicting non-concentric shrinkage mode(NCSM).Methods Sixty-one women with pathologically proven solitary invasive ductal carcinoma (ⅡA-ⅢC)were recruited. Breast specimen was prepared with PMSS, and residual tumors were microscopically outlined,scanned and registered by Photoshop CS 5 software.The 3D model of residual tumors was reconstructed with 3D-DOCTOR 4.0 software to evaluate the shrinkage mode.17 factors such as age and body mass index and menopausal status were chosen as independent variables,and the clinic-pathologic shrinkage mode was considered as dependent variable. A Logistic regression model was used to construct the nomogram. Results Primary tumor stage,lymph node down-staging, PR and mammographic malignant calcification before NAC were independent predictors of clinic-pathologic shrinkage mode (β:1.538,OR:4.656,95%CI:1.414-15.328,P=0.011;β:1.555,OR:4.735, 95%CI:1.082-20.722,P=0.039;β:-1.707, OR:0.181, 95%CI:0.044-0.741,P = 0.017;β:- 1.405, OR:3.808, 95% CI:0.06 - 0.998,P = 0.048, respectively ). The nomogram predicting the risk of NCSM showed a good concordance index(0.869),and its conformity of mean absolute error was 0.039. Conclusion Based on the clinicopathological findings of primary breast tumor, a nomogram to predict shrinkage modes after NAC in breast carcinoma patients is constructed.The statistical tool is helpful for individually selecting the patients who can be treated with BCT after NAC.

OBJECTIVETo investigate the clinical features and treatment in patients of marginal zone lymphoma (MZL)with monoclonal immunoglobulin (McIg).

METHODSThe clinical data of MZL patients with McIg, including 3 cases diagnosed and treated in Beijing Anzhen Hospital from Jan 2007 to Dec 2014 were retrospectively studied, meanwhile 36 patients searched from literatures were reviewed.

RESULTSOf a total of 39 patients, the ratio of male and female was 1.05∶1 with an average age of 65.1± 12.3 years old. 28 cases (71.8%)were with mucosa associated lymphoid tissue lymphomas (MALTL), 9 cases (23.1% )with nodal marginal zone lymphoma, and 2 cases (5.1%)with splenic marginal zone lymphoma. Nine cases (23.1% )were in the early stage, 30 cases (76.9%)in the advanced stage. The common initial symptom was non-mass lesions (65.5%), such as skin purpura, peripheral neuropathy; 13 patients (33.3% )were accompanied by autoimmune phenomenon, and most were with Sjogren's syndrome. Among MALTL patients, the common primary lesion was in non- gastrointestinal tract (17 cases, 60.7%). Most of patients with McIg were one with McIgM (82.0%); the others with McIgA, Mcκ-light chain, McIgG and double McIg. The level of plasma McIgM was (25.55±21.31)g/L, which was higher in advanced stage patients than in early stage ones [(29.85±20.60)g/Lvs (3.23±2.95)g/L,P= 0.008]. The complete remission (CR)rate was 56.0% and the overall response rate (ORR)92.0%, respectively in 30 patients treated by chemotherapy. At a median follow- up of 10 months, the 3- year progression free survival and the 3-year overall survival were 44.7% and 76.5%, respectively. The rates of ORR and CR in the patients received rituximab- included regimen were seemly better than those without rituximab one (100.0%vs 78.6%, 63.6%vs 50.0%;P>0.05), but no statistic differences were found. The CR rate in patients with McIgM was significantly higher than that with non- McIgM (P=0.026). The plasma McIgM level decreased after chemotherapy (P=0.002).

CONCLUSIONThe MZL with McIg, perhaps a kind of unique subtype, usually occurred in 60 years or older patients. It was often diagnosed in patients of advanced stage and susceptible to autoimmune phenomenon. MALTL in non- gastrointestinal tract was more prone to find McIg. In MZL patients with McIg, McIgM was more common and other McIg rare. Rituximab-included regimen produced a better therapeutic response.

Objective To verify the accuracy of the modified technique for internal mammary sentinel lymph node biopsy ( IM-SLNB) in breast cancer .Methods In the validation study , the radiotracer was injected with the modified technique , and fluorescence tracer was injected into the peritumoral breast tissue .The radioac-tive IM-SLN was identified by preoperative lymphoscintigraphy and γprobe.The radioactive IM-SLN received bi-opsy during operation .The status of the fluorescence tracer was identified by the fluorescence imaging system . Results A total of 162 patients were enrolled from Sep .2013 to Dec.2014.IM-SLNB was performed in 110 pa-tients.The radiotracer and the fluorescence tracer were identified in the same IM-SLN in 94 cases, and the con-cordance rate was 85.5%(Case-base, Spearman coefficient correlation 0.823, P<0.001).Conclusion Dif-ferent tracers injected into the different sites of the intra-parenchyma can reach the same IM-SLN, proving the ac-curacy of the modified technique and the hypothesis of IM-SLN lymphatic drainage pattern ( IM-SLN receives not only the lymphatic drainage from the primary tumor area but the entire breast parenchyma ) .

ObjectiveTo evaluate the risk factors for sentinel lymph node(SLN)metastasis,and assess the value of the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram in predicting SLN metastasis in breast cancer patients.Methods A sentinel lymph node biopsy(SLNB) database containing 1227 consecutive breast cancer patients(412 patients with a positive SLN)was retrospectively analyzed.The value of MSKCC nomogram was predicted by drawing the trend line and calculating the area under the curve(AUC) of receiver-operator characteristic(ROC). Meanwhile,the risk factors of SLN metastasis were evaluated. Results Tumor size,tumor location,histological grade,lymphovascular invasion,mulifocality,ER and PR status were correlated with SLN metastasis( all P ＜ 0.05 ).All the above factors but tumor location were significant independent predictors for SLN metastasis(all P ＜ 0.01 ).The MSKCC nomogram presented AUC value of 0.730 for ROC.Patients with predictive values lower than 16％ had the frequency of 0.9％ for SLN metastasis while patients with predictive values higher than 70％ had the frequency of 96.2％.ConclusionsThe risk factors of SLN metastasis in our study are consistent with those in MSKCC nomogram.MSKCC nomogram is a useful tool in predicting the probability of SLN metastasis for breast cancer patients.Axillary surgery can be avoided in patients with the predictive values lower than 16％,axillary lymph node dissection could be done in patients with the predictive values higher than 70％,and other patients should still undergo SLNB.
