Journal of Zhejiang Chinese Medical University 2016;40(10):747-749
Objective] Summarize the experience of diagnosis and treatment of plasma cell mastitis by Gu ’s surgery department. [Method] By collecting medical records, from the teachers, pathogenesis, to summarize the inheritance and development of diagnosis and treatment of plasma cell mastitis by Gu ’s surgery department three generations, according to the present situation, analysis of the problems existing in the treatment of the disease. [Results] The disease was first discovered and reported by Dr.Gu Bohua in the domestic.Gu’s surgery department gradually gropes for a set of solution method in treatment of plasma cell mastitis after three generations from the treatment based on the external therapies in the initial, to later, internal and external therapies, at present based on the internal therapies. Clinical studies have found that the internal and external therapies have advantages of high cure rate, short treatment time, but the scar is larger, while the internal therapies in the long treatment cycle achieve the same cure rate, but the scar is smaller, less expensive. But the exploration of the cause of the disease, diagnosis and standardized treatment is still fraught with problems. [Conclusion]Developing by three generations, Gu ’s surgery department provides a more complete mentality and pragmatic value in treating plasma cell mastitis.

Objective To investigate the inhibitory effect of dendritic cells (DCs) and homologous cytokine-induced killer cells (CIKs) on the growth and liver metastasis of human primary malignant melanoma of the small intestine. Methods A histologically intact liver metastasis fragment derived from a surgical specimen of patients with primary malignant melanoma of the small intestine was implanted in the mucous layer of small intestine in nude mice to construct the liver metastasis model of the malignant melanoma. Peripheral blood mononuclear cells from healthy donors and patients with malignant melanoma of the small intestine were isolated. DCs and CIKs were separately produced according to corresponding culture method, and the DC-CIKs were harvested after coculorthotopically implanted in 56 nude mice, and 72 hours later, all the mice were equally divided into normal saline group (0.3 ml), mitomycin treatment group (400 μg/0.3 ml), healthy donor CIK group (6 × 107/0.3 ml),healthy donor DC-CIK group (3 × 107/0.3 ml), autologous CIK treatment group (6 × 107/0.3 ml), autologous DC-CIK group (6 × 107/0. 3 ml) and DC-CIK (6 × 107/0.3 ml) + mitomycin (400 μg/0. 3 ml) treatment group. Mice in the experimental groups were administered the agents once daily by vena caudalis injection for 28 days. Mice were sacrificed 72 hours after treatment, and the orthotopic xenografts were removed for weighing,and the liver metastases were simultaneously evaluated by macroscopy and microscopy. All data were analyzed using the analysis of variance, LSD test and chi-square test. Results A liver metastatic model of human primary malignant melanoma of the small intestine ( HSIM-0603 ) was established. Of the control group, healthy donor CIK group, healthy donor DC-CIK group, autologous CIK treatment group, autologous DC-CIK group and DC-CIK +mitomycin group, the tumor weights were ( 1.18 ± 0. 17), (0.71 ± 0.06), (0.68 ± 0. 15 ), (0. 43 ± 0.08 ),(0.67 ± 0.07 ), (0.37 ± 0.08 ) and (0.20 ± 0.05 ) g, respectively; the tumor inhibition rates were 0, 39.82%,42.37%, 65.56%, 43.22%, 68.64% and 83.05%, respectively; liver metastases were detected in 8, 8, 5,4, 4, 3, 2 rats, respectively, in the above mentioned groups. There were significant differences in the tumor weight, tumor inhibition rate and liver metastasis rate among the seven groups (F = 152. 300, x2= 200. 538,94. 325, P < 0.05 ). Conclusions The liver metastatic model could be applied to the studies on the pathogenesis,invasion, metastasis and treatment of human primary malignant melanoma of the small intestine. DC-CIK has the potential in inhibiting the growth and liver metastasis of the malignant melanoma of the small intestine.

Objective To replicate an ideal animal model for exploring pathogenesis and experimental treatment of malignant lymphoma of small intestine. Methods Fresh lymphoma tissues derived from primary lesion and liver metastasis of malignant lymphoma of human small intestine obtained during operation were respectively transplanted into mucosa of small intestine and subcutaneous space in the interscapular region in nude mice. Tumorigenicity, invasion and metastasis of transplanted tumors were observed. Morphology (light microscopy, electron microscopy and immunohistochemistry), karyotype analysis, DNA quantitative assay (FCM) were also studied. Results From five patients of malignant lymphoma of small intestine, tumor tissue from 3 patients was successfully transplanted. According to the new classification of the World Health Organization, a strain of high metastatic model of orthotopically transplanted malignant lymphoma in nude mice (HSIL-0101) and another of subcutaneously transplanted highly metastatic model were reproduced from the same human neoplasm (non-Hodgkin B cell type); orthotopically Pathological study showed that the tumor was high-grade large B-cell lymphoma. Histochemitry showed that it was CD19, CD20, CD22 and CD45 positive, and CD3 and CD7 negative. The number of chromosome is ranged from 55 to 59; DI (DNA Index) was 1.47~1.61 (ie, heteroploid). HSIL-0101 and HSIL-0102 had been passaged for 32 and 38 generations in nude mice separately. 357 nude mice were transplanted. Rate of growth of neoplasm transplantation and resuscitation rate of liquid nitrogen cryopreservation were both 100%. In HSIL-0101, metastasis rate of liver and lymph node was 100%. In HSIL-0102, metastasis rate of liver was 63.5% and metastasis rate of lymph node was 62.7%. Transplanted tumors invasively grew in small intestine and subcutaneous region of nude mice. Blood metastasis was found (liver and spleen metastases). There were also lymph metastasis and seeding metastasis in the peritoneal cavity. Conclusions The study first successfully established spontaneous high metastasis models of malignant lymphoma of human small intestine in nude mice by orthotopic and subcutaneous transplantation. HSIL-0101 and HSIL-0102 could be used to carry out the research on pathogenesis, invasion, metastasis, and experimental therapy of malignant lymphoma of small intestine.

Objective To study the synergistic effect of endostatin (YH-16) and irradiation on human non-small cell lung cancer (NSCLC) cell line A549 and the expression level of vascular endothefial growth factor. Methods ① A549 cells were exposed to various concentrations of endostatin for different time. The optimal concentration giving ≤20% inhibition concentration (IC20) by MTT assay was selected. ② The cells were divided into 4 groups:control group,chemotherapy alone,radiotherapy alone,and radio-chemotherapy group. All groups were exposed in distinct treatment,the cells survival fraction and the plating efficiency of the four groups provided to select the optimal radiotherapy dosage. ③ The radio-chemotherapy group had been exposed to endostatin for 48 hours,followed by irradiation at 48 hours with various doses:0,2,4,6,8 Gy. After 14 days,the cell clonogenic survival curves and the SER were evaluated. ④ Detect the different groups' VEGF value by ELISA kit. Results Incubating cells in 200 mg/L endostatin culture medium the value of SER radiated by linear accelerator in 2 Gy after 48 h were 1.61 and 1.04. And endostatin with proper dosage and radio-exposure time could decrease the VEGF level. Conlusion It is suggested that endostatin enhances the radiosensitivity of NSCLC A549 cell line in vitro (SER=1.61,1.04). The enhancement depends on the time of exposure drug. The optimal radiation time should be 48 hour after exposure.
