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.

Triple negative breast cancer (TNBC) has its own exclusive pathological and molecular biological characteristic.At present,the treatment guidelines for triple negative breast cancer is not perfect,and the chemotherapy is the main method.A deeper insight into the targeted therapy of TNBC can improve the curative effect.

1 cases of pleomorphic hyalinizing vascular tumor(PHAT) at the right side of neck soft tissue is reported and related literatures are reviewed.The clinical symptoms of PHAT are mild and non-characteristic,imaging examination and postoperative pathological examination may show specificity of the lesion.It is a kind of soft tissue tumor with malignant tendency.Surgical excision is the main treatment,long-term follow-up is recommended.

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 study the clinical result of Endo-Model rotating-hinge prosthesis in the treatment of severe knee deformity. [Method]Twenty-two patients(10 males and 12 females;12 right knees,8 left knees,and 2 bilateral knees) were selected for total knee arthorplasty using Endo-Model rotating-hinge prosthesis.The average age was 56.2 years.All the patients were evaluated by HSS score system.[Result]All incisions healed at one-stage and all malformations were corrected.The functional result was good.Mile deep vein thrombosis was found in one case after operation.All the patients were followed up for 6-55 months.No infection or prosthetic loosening was developed.[Conclusion]Endo-Model rotating-hinge prosthesis is an effective and reliable prosthesis for severe knee deformity.

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.

Spasticity is a common complication of stroke.It may cause the function and ability of patients to be restricted significantly and affect the quality of life of both patients and their caregivers.The estimated prevalence of poststroke spasticity (PSS) is 19％ to 42.6％.PSS can be usually assessed by the Modified Ashworth Scale,Modified Tardieu Scale,and electromyography.Therapeutic methods of PSS include physical therapy and drug treatment.The treatment options should be individualized.

Circulating tumor cells (CTCs) are present in the peripheral blood,and play an important role in the recurrence and metastasis of lung cancer.As the researches about CTCs and targeted therapy move along,it is found that CTCs can be used as a liquid tumor tissue to guide clinical treatment and have a certain significance in the clinical staging and prognosis evaluation of lung cancer.

Objective To explore MRI appearances of malignant mixed mesodermal tumors (MMMT) of the uterus. Methods All 9 patients with MMMT were proved by pathology. MRI characteristics of MMMTs in 9 patients were analyzed retrospectively.Results Of 9 MMMTs,6 were uterus body-based and 3 were cervical-based.Body-based MMMTs tended to be expansive or infiltrative growth with expanded uterus cavity. Cervical-based.MMMTs tended to be exophytic growth without myometrial infiltration. The tumors presented iso- or low signal on T1WI. The body-based MMMTs presented heterogeneously hyper-intense on T2WI ( n =5 ),hemorrhage ( n =1 ),cystic degeneration and necrosis (n =5) were seen within the tumors. Cervical-based MMMTs presented relative hyper-intense signal on T2WI with band or tree-like hypo-intense signal,without hemorrhage and necrosis. Body-based MMMTs were enhanced more obviously than cervical-based MMMTs.Conclusions The growth pattern,MRI signal and enhancement characteristics of cervix and uterus body MMMTs are different. MRI is helpful for the diagnosis of MMMT.
