Objective To investigate the clinical characteristics of elderly patients with multiple myeloma and their prognostic factors.Methods 100 multiple myeloma patients with age≥ 60 years and 100 multiple myeloma patients with age <60 years who admitted in our hospital from December 2007 to December 2015 were collected as research subjects.100 patients with age ≥60 years were divided into elderly multiple myeloma group,100 cases with aged <60 years were divided into non -elderly multiple myeloma group.The clinical data and laboratory results of two groups were compared,the prognosis factors in elderly patients with multiple myeloma were analyzed.Results The incidence rate of ISS stage Ⅰ -Ⅱ in elderly multiple myeloma group (45.0%)was lower than non -elderly multiple myeloma group (60.0%),the incidence rate of stage Ⅲ was higher than non -elderly multiple myeloma group (χ2 =4.511,P <0.05).The infection incidence of elderly multiple myeloma group(30.0%)was higher than non -elderly multiple myeloma group(15.0%)(χ2 =10.452,P <0.05 ).The hemoglobin,serum albumin contents of elderly multiple myeloma group [(83.7 ±19.8)g/L,(27.89 ±6.87)g/L]were less than non -elderly multiple myeloma group[(92.1 ±22.5)g/L,(33.15 ±7.69)g/L](t =4.297,4.426,all P <0.05).The calcium content,the propor-tion of bone marrow plasma cells,serum creatinine and blood β-microspheres protein levels of elderly multiple mye-loma group [(2.51 ±0.41)mmol/L,(39.43 ±18.64)%,(182.24 ±125.47)μmol/L,(9.02 ±6.24)mg/L]were higher than non -elderly multiple myeloma group [(2.36 ±0.48)mmol/L,(37.45 ±19.86)%,(143.25 ± 116.43)μmol/L,(5.87 ±3.41)mg/L](t =5.945,4.196,4.375,4.264,all P <0.05).The median survival time of elderly multiple myeloma patients were significantly correlated with the patients'age,the proportion of plasma cells in bone marrow,blood β2 -microglobulin,albumin,and ISS staging (χ2 =4.125,3.254,8.542,5.748,9.244,all P <0.05).Conclusion The condition of elderly myeloma patients is more serious,age,proportion of plasma cells in bone marrow,blood β2 -microglobulin,albumin and ISS stage affect myeloma patients prognosis.

Objective To investigate the expression of survivin and its correlation with tumor thymidine kinase and axillary lymph node metastasis in breast cancer. Methods Expression of survivin and cytosolic thymidine kinase(TK) in 60 cases of breast cancer(28 cases with axillary lymphonode metastasis) were measured by immunohistochemistry. Results There was expression of survivin in breast cancer; labeling index(LI) of TK in breast cancer cells with positive expression of survivin was significantly higher than that with negative expression of survivin;the positive percent of survivin expression in breast cancer with axillary lymph node metastasis was higher than that without axillary lymph node metastasis. Conclusions The expression of survivin in breast cancer is related to TK and axillary lymph node metastasis.

Objective To investigate if vascular endothelial growth factor-D(VEGF-D) and endostatin(ES) promote angiogenesis in colorectal cancer(CRC). Methods One hundred and five patients undergoing CRC surgery were enrolled in this study. CRC and normal tissue microarray were produced and measured for VEGF-D and ES by immunohistochemmical staining.Results VEGF-D and ES expression were stronger in CRC tissues than in control normal mucosa. MVD was higher in cancer tissues than in normal ones. ES down-regulated expression was associated with less invasiveness, positive lymph node metastasis, distant metastasis and in cases of early Dukes′ stage, while the expression of VEGF-D in corresponding tissues was on the opposite to ES. MVD increased along with tumor invasion, lymph involvement, distant metastasis and late Dukes′ stage. Conclusions VEGF-D in accord with ES promotes the angiogenesis and progression of CRC.

Objective To construct the expression vector of early growth response-1 promoter-macrophage inflammatory protein 3? (pEgr-1-MIP-3?, pEM) to study MIP-3? expression in transfected Lewis lung cancer cells. Methods MIP-3? cDNA was inserted into plasmid with Egr-1 promoter by directional cloning. The vectors were transfected into Lewis lung cancer cells with liposomes. The expression of MIP-3? in transfected Lewis lung cancer cells induced by electron ray irradiation at different doses were confirmed by RT-PCR and Western blotting. Results The recombinant vector was sequenced, and the result indicated the correct insertion in the expression vector. After electron ray irradiation at different doses, MIP-3? expression in the transfected Lewis lung cancer cells increased significantly. Conclusion Electron ray can enhance the expression of MIP-3? in Lewis lung cancer cells. This has laid the experimental foundation for the studies of pEM for radio-genetic therapy in vivo.

Objective To evaluate the distribution of neuropeptide Y and its receptors in the cardinal ligament and uterosaeral ligaments in women with and without pelvic organ prolapse(POP).Methods Sixteen patients with pelvic organ prolapse entered the study.All patients were evaluated by pelvic organ prolapse quantitation(POP-Q).Group A consisted of six patients with grade Ⅰ,Ⅱ POP,and group B comprised ten patients with grade Ⅲ,Ⅳ POP.Eight nonfunctional ovarian tumor patients without POP were recruited as control subjects.Biopsies of cardinal ligament and uterosacral ligament were obtained from each woman during surgery.Immunohistochemical study with polyclonal antibody against a general nerve marker S-100 and neuropeptide Y was performed on paraffin-embedded sections of all the samples.In addition,mRNA levels of the human NPY-Y1 and NPY-Y2 receptors were assessed in both patients and controls.Results (1)NPY immunoreactivities were identified in both cardinal ligament and uterosacral ligament. NPY immunoreactive nerve fibers were insignificantly lower in POP patients(P＞0.05).The distribution pattern of NPY was similar in cardinal ligament and uterosacral ligament ( P＞0. 05 ). (2)mRNAs encoding the NPY-Y1 and NPY-Y2 receptors were detected in the pelvic supporting tissues. Besides the expected NPY-Y1 PCR products, an additional 97 bp long amplicon originating from an alternative splicing event was found in most tissues studied. (3)In cardinal ligaments, mRNA encoding NPY-Y1 receptor had a significant difference between group A(3.9±1.0)and B (6. 0±1.5), and between control (3.4±0.9) and group B (P = 0. 019,P = 0. 004), while there was no significant difference between group A and controls(P =0. 082). In uteresacral ligaments, mRNA encoding NPY-Y1 receptor had no significant difference between Group A(6. 0±1.1) and B (6. 3±0. 7), or between group A and controls(4. 8±0. 7;P = 0. 151 ,P = 0. 690);while there was a significant difference between group B and controls (P = 0. 016).(4) mRNA encoding NPY-Y2 receptor had no significant difference between controls (0. 49±0. 34, 0. 61±0. 15 ), group A (0. 56±0. 21,0. 67±0. 13) and group B (0. 85±0. 43, 0. 69±0. 21 ) patients in cardinal ligament and uterosacral ligaments ( P＞0. 05 ). (5) mRNA encoding NPY-Y1 ( P = 0. 084 ) and NPY-Y2 (P=0.470) receptors had no significant difference between cardinal ligament and uterosacral ligament.Conclusions There are NPY and NPY receptors in cardinal and uterosacral ligaments. The increased expression of NPY Y1 receptor may be related to local blood flow reduction and structural changes of pelvic supporting tissue.

Objective To study cancer metastasis in mesorectum and ischiorectal loss in cases of ultra-low rectal cancer and evaluate the rationale of Miles procedure. Methods Whole-mount slice and tissue mieroarray technique were used to study the dissected specimen from 23 cases of uhra-low rectal cancer for metastatic lymph nodes. Result 415 lymph nodes were harvested in 23 mesorectum specimen, 169 and 59 lymph nodes were metastasic and micrometastasie respectively. 12 eases were diagnosed with metastasis, 4 cases were found to have micrometastasis. Metastatic lymph nodes in the lateral and anterior mesorectum were 29.0% (49/169) and 17.2% (29/169) respectively. There were 2 patients with metastasis and 1 with micrometsstssis in ischiorectal fossa lymph nodes, accounting for 13% patients. Conclusion Regional metastasis exists in ultra-low rectal cancer and its incidence varies in different location of mesorectum and ischiorectal fessa. The value of Miles procedure as the standard therapy for ultra-low rectal cancer should undergo an evaluation.

Objective To investigate the prevention and management of anastomotic leakage in patients with middle and lower rectal cancer after neoadjuvant therapy.Methods In this study,50 cases of middle or lower rectal carcinoma underwent anus preserving radical resection and anastomosis after a 4 cycles of chemotherapy with FOLFOX and 46 Gy(2 Gy×23)radiotherapy.Anastomotic leakage,the prevention and management of this complication were analyzed retrospectively.Results All these 50 patients received low anterior resection after chemoradiotherapy,among the 19 cases receiving prophylactic ileac stoma simultaneously,there was no anastomotic leakage,whereas anastomotic leakage developed in 4 out of the 31 patients who did not receive prophylactic ileac stoma,including concomitant rectovaginal fistula in 2 cases.All these fistulae were cured conservatively.Conclusion Concomitant treatment of FOLFOX regimen and RT in neoadjuvant setting of rectal cancer could increase the rate of anal interior sphincter reservation,prophylactic ileac stoma helps to reduce the rate of anastomotic leakage after a anus-preserving low anterior resection of the cancer.
