Objective Ultrasonongraphy and mammography were employed to estimate the pathological response of patients with breast cancer ,who had been accepted neoadjuvant chemotherapy .According to the pres-ent study ,we can provide additional evidence on therapeutic effect on evaluation of neoadjuvant chemotherapy and better selection of regime for breast cancer .Methods One hundred Thirty-six patients who were previously dia-gosed diagnosed with primary breast cancer were included in this study .All subjects were female with clearly pathological detection and accepted neoadjuvant chemotherapy about 4 to 6 cycles regardless of regime .The resid-ual tumor size was evaluated by mammography and /or ultrasonography before operation .Tumor size measured by image were compared with pathological size to predicting the accuracy of two types of imaging .Results Forty one of 116 records were undetectable imaging by mammogram and 19 of 106 records were undetectable by ultrasound which were considered a pathologic complete response .Sixty one(62.24%)of 98 patients who were accepted de-tection of mammogram and ultrasound would be predicted the tumor size by mammogram .Eighty three(84.69%) of 98 patients would be predicted the residual tumor by ultrasound .31 and 59 were accurately evaluated by mam-mogram and ultrasound , respectively .The result indicated that ultrasound was more accurate than mammogram (60.20%vs.31.63%,χ2 =16.11,P<0.001).The correctly rate was 92.85%(91/98)for ultrasound and 68. 37%(67/98) for mammogram.The diagnosis efficiency of ultrasound was more higher than mammogram ,even though there was no different significance between the two methods (χ2 =2.028,P=0.164).Conclusion Ultra-sonongraphy in estimating the residual tumor size after neoadjuvant chemotherapy of patients with breast cancer displays more accurately than mammography .

Objective To explore the interventional treatment method for complex and refractory lymphatic malformation in children.Methods The clinical data of 78 cases with complex and refractory lymphatic malformation during January 2013 to January 2016 in our department were retrospectively analyzed.The lesions involved the neck in 28 cases,maxillofacial regions in 19 cases,the chest and armpit in 8 cases,the limb in 7 cases,the pelvic cavity and retroperitoneal space in 6 cases,the superior mediastinum in 3 cases,the hypogloeeis in 3 cases and scrotum or perineum region in 4 cases.All the children underwent ultrasound or MRI imaging studies preoperatively.The interventional procedures included:(1) Percutaneous puncture of the LM for sclerotherapy.The lesions were punctured with 20 G needle under the guidance of DSA or ultrasound and the correct positions were confirmed with angiography.The liquid of the lesions was extracted as far as possible.The dosage of sclerosing agents was adjusted according to the size of lesion.The dose of Laurolacrogol injection was 1/10—1/5 of the amount of the liquid in the lesions and the maximum of Laurolacrogol foam was ≤8 ml(20 mg).The dose of Pingyangmycin was ≤ 8 mg.(2) The drainage catheter placement and sclerotherapy.Percutaneous catheter drainage under ultrasound guidance or by surgery was conducted.The liquid in the lesions was drained by retaining the catheter for 1-4 weeks,and sclerotherapy was applied for several sessions during this period.(3) Treatment for one time a week,2 times a session.The interval of every two sessions was 4 weeks.The sclerosing agents included:Laurolacrogol Injection or Pingyangmycin for the lesions with high tension,Laurolacrogol foam for the lesions with low tension,Pingyangmycin for the microcystic lesions.Statistical analysis was conducted using SPSS20.0 software.Results A total of 208 sessions of sclerotherapy for 78 LM patients were performed and average session was (3.0±0.8).Nine patients used Lauromacrogol foam,23 patients used Lauromacrogol Injection,39 patients used pingyangmycin,while combined treatment was conducted in 7 patients.Laurolacrogol injection was used in 20 cases,Pingyangmycin in 29 cases and combination therapy in 5 cases for the high tension lesions in the neck,maxillofacial,chest and armpit.The low tension lesions of pelvic cavity and retroperitoneal space in 6 cases and of superior mediastinum in 3 cases were placed with draining catheters,and treated with sclerotherapy with Laurolacrogol foam.Three cases with hypogloeeis LM was neonates,who were treated with Laurolacrogol injection.The lesions on the limb and scrotum or perineum region were almost microcystic,were treated with Pingyangmycin in 9 cases and with combination therapy in 2 cases.The total curative rate was 97.4％ (76/78),total effective rate was 100％ (78/78).Imaging examinations showed that the cavities were closed or only a small amount of residual sclerotic lesions were present.Clinical examinations showed that the surface masses almost disappeared.The follow up period was 6 months to 2 years.There were no serious complication and adverse reactions occurred.Conclusions Interventional treatment is a safe,effective,and minimally invasive treatment for the complex and refractory lymphatic malformation.In order to receive the best treatment effect,we should use targeted therapy for different region and type of LM.

Objective To explore therapeutic effects of different interventional approaches to neonatal Kasabach-Merritt syndrome (K-MS) Methods A retrospective analysis of therapeutic effects of different interventional approaches to K-MS in 12 neonates from May 2010 to August 2014. All the patients received local treatment (n=5), chemoembolization (n=4) and combined local treatment and endovascular chemoembolization (n=3), respectively, depending on size, location and blood supply of K-MS. The K-MS patients with angioma measuring< 5 cm, 5 to 10 cm and >5 cm received local treatment, endovascular chemoembolization and combined local treatment and endovascular chemoembolization, respectively. The patients were categorized as cured, improved and clinical inefficient, respectively, based on therapeutic effect. The criteria for cured patients were: (1) angioma faded completely or mostly; (2) the platelet count stabilized within the normal range; (3)no recurrence for more than six months. The criteria for improved patients were: (1) angioma shrinked significantly; (2) the platelet stabilized within the normal range. The criteria for clinical inefficient patients were: (1) agioma no obviously shrinked, the platelet count has no improvement over 2 months after interventional approaches. Results All the 12 patients with K-MS were cured and had no complication. Of the 12 patients, 5 patients received local treatment had decreased localized tension and ecchymosis of hemangioma at the first day of therapy, were cured after 2 to 7 courses of therapy. Of the 4 patients received endovascular chemoembolization, 3 were cured after one course of treatment, 1 had recurrent disease one month later after one course of therapy and were cured after the second course of treatment.One had recurrent disease a month later after one course of treatment and were cured after the second course of treatment. Three received combined local treatment and endovascular chemoembolization, angioma shrinked significantly and increased platelet count after the first course of treatment, and 2 to 3 courses local treatment were combined, hemangioma faded and platelet count stabilized within the normal range after 2 to 3 courses of local treatment. Conclusions Interventional therapy is the most effective treatment of neonatal K-MS.There are different interventional approaches to optimize treatment of neonatal K-MS depending on sizes, location and blood supply of K-MS.

BACKGROUND: Tumor-adopted immunity and gene transduction technique are used to introduce tumor necrosis factor-α vector into carrier cells, which are then re-infused into the body so that cancer cells can be killed by tumor necrosis factor-α more directly and effectively with fewer side effects on the other tissues due to high local expression.OBJECTIVE: To study the bioactivity of in vitro cultured tumor necrosis factor-α transduced tumor-infiltrating lymphocytes as well as the inhibitory effects on cancer cells of cancer-loaded rats infused in different ways.DESIGN: A randomized controlled study based on experimental animals.SEETING: Cancer Research Institute of China Medical University.MATERIALS: This study was carried out at the Cancer Research Institute and the Experimental Animal Department, China Medical University,between January 2000 and December 2001. TJ8510 cell line (human brain glioblastoma cell line) was provided by the Neurological Research Institute of Tianjin Medical University Affiliated Hospital. The experimental animals were 36 BALB/C nude mice congenitally having no thymius.METHODS: Based on the establishment of tumor necrosis factor-α retroviral transduction system and the preparation of cartier cells tumor-infil-trating lymphocytes, the monoclonal virus cell line PLC-2 and PLJC-5available were used to introduce marked gene NeoR and targeted gene tumor necrosis factor-α into tumor-infiltrating lymphocytes, respectively.Then cell proliferation, tumor necrosis factor expression and in vitro antitumor activity were examined. After cancer cell inoculation, the 36 nude mice were randomly divided into 6 groups: local infusion control group, local tumor-infiltrating lymphocytes infusion group, local tumor necrosis factor-tumor-infiltrating lymphocytes infusion group, venous infusion control group, venous tumor-infiltrating lymphocytes infusion group and venous tumor necrosis factor-tumor-infiltrating lymphocytes infusion group, and the therapeutic effects on the cancer-loaded mice were observed.proliferation and tumor necrosis factor-α expression in tumor-infiltrating oR-tumor-infiltrating lymphocytes and tumor necrosis factor-tumor-infiltrating lymphocytes was not significantly different from each other (P ＞ 0.05).NeoR-tumor-infiltrating lymphocytes, though not significantly different (P ＞0.05), significantly differ from that of tumor necrosis factor-tumor-infiltrating lymphocytes (P ＜ 0.01); moreover, tumor necrosis factor-tumor-infiltrating lymphocytes were found to express higher tumor necrosis factor-α conactivity did not significantly differ between tumor-infiltrating lymphocytes and NeoR-tumor-infiltrating lymphocytes (P ＞ 0.05), but obviously increased come of the animal experiment: 40 days after tumor necrosis factor-tumorinfiltrating lymphocytes infusion, cancer size in local tumor necrosis factortumor-infiltrating lymphocytes infusion group was found smaller than that in local infusion control group [(307±42) and (2 048±278) mm3, P ＜ 0.01],and it was also smaller in venous tumor necrosis factor-tumor-infiltrating lymphocytes infusion group than that in venous control group [(954±195)and (1 989±305) mm3 , P ＜ 0.05].CONCLUSION: Tumor necrosis factor-α gene transduced tumor-infiltrating lymphocytes could effectively express tumor necrosis factor, exerting higher and in vivo anti-tumor effects than tumor-infiltrating lymphocytes in cancer-loaded nude mice. No obvious inhibitory effects on the growth of subcutaneous solid carcinoma could be observed in nude mice after venous infusion of human brain glioblastoma tumor-infiltrating lymphocytes, but the inhibitory effects became obvious due to venous infusion of tumor necrosis factor-tumor-infiltrating lymphocytes and significant due to local tumor necrosis factor-tumor-infiltrating lymphocytes infusion, indicating that local infusion is the preferable way in the treatment of glioblastoma by immuno-gene therapy.

Aim To study the anti-tumor effect of 20(S)-Protopanaxadiol(PPD)at different concentration on human liver cell line SMMC-7721 in vivo and in vitro.Methods The subcutaneous transplantable tumor model of human liver cancer in nude mice was established and the anti-tumor effect was calculated.Cell growth rate was determined with MTT assay.The apoptosis was analyzed by FITC-AnnexinⅤ/PI and Hoechst33342 staining method,and the activity of Caspase-3 was detected.Results In vivo,PPD could obviously inhibit the growth of transplanted tumor.In vitro,PPD induced inhibition of human liver cancer SMMC-7721 cells was time-dependent and dose-dependent.The apoptotic body was observed by Hoechst33342 staining.PPD could induce cell apoptosis of SMMC-7721,and the increase of Caspase-3 activity was observed in each PPD group.Conclusion PPD could inhibit the growth of human liver cancer SMMC-7721 cells in vivo and in vitro by up-regulating the activity of Caspase-3 and inducing the cell apoptosis.

Malignant tumor is one of the main causes for death in the world at present as well as a major disease seriously harming human health and life and restricting the social and economic development. There are many kinds of reports about traditional Chinese medicine patent prescriptions, empirical prescriptions and self-made prescriptions treating cancer, and prescription rules were often analyzed based on medication frequency. Such methods were applicable for discovering dominant experience but hard to have an innovative discovery and knowledge. In this paper, based on the traditional Chinese medicine inheritance assistance system, the software integration of mutual information improvement method, complex system entropy clustering and unsupervised entropy-level clustering data mining methods was adopted to analyze the rules of traditional Chinese medicine prescriptions for cancer. Totally 114 prescriptions were selected, the frequency of herbs in prescription was determined, and 85 core combinations and 13 new prescriptions were indentified. The traditional Chinese medicine inheritance assistance system, as a valuable traditional Chinese medicine research-supporting tool, can be used to record, manage, inquire and analyze prescription data.

The effect of water extracts of Euphorbia hirta on the histological features and expressions of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) in the rat articular cartilage was investigated. Arthritis was induced in rats using Freund's Complete Adjuvant containing heat-killed M. tuberculosis, and treated with water extracts of E. hirta. Paraffin tissue sections of the arthritic joints were evaluated. The extent of cartilage degeneration was found to be greatest in rats treated with the highest dosage of E. hirta, followed by rats in the untreated group. Rats treated with the intermediary and low dosages of Euphorbia hirta showed improved histology. MMP-13 levels were found to be decreased with decreasing dosages of E. hirta. TIMP-1 levels were found to increase with decreasing dosages of E. hirta. MMP-3 levels fluctuated without any appreciable pattern. Low dosages of E. hirta seem to be beneficial in reducing cartilage degeneration in cases of arthritis.
