Purpose To explore the clinicopathologic characteristics, pathologic diagnosis and differential diagnosis of extraskeletal myxiod chondrosarcoma. Methods The clinical and pathological features were studied with HE and immunohistochemical staining in 5 cases of extraskeletal myxoid chondrosarcoma, and the related literatures were also reviewed. Results Extraskeletal myxoid chondro-sarcoma was male predominance (4 males: 1 female), and the age ranged from 32 to 62 years with an average of 52 years. Four tumors occurred in thigh and another in chest. Histologically, the neophlasm were composed of round and oval cells. Immunohisto-chemically, the tumor cells were positive for vimentin in five cases, synaptophysin expressed in one case, S-100 showed focal positivity in two cases, but negative for CK, p63, EMA, CD34, SMA in all cases. Molecular genetics detection shows chromosome exchange be-tween number 9 and 22. Conclusion Extraskeletal myxoid chondrosarcoma is a rare tumor which has no special characteristics in clinical and iconography, and its diagnosis mainly depends on the histopathologic features, immunohistochemistry and molecular genet-ics. Extraskeletal myxoid chondrosarcoma grows slowly, but have a high tendency for local recurrence and metastases.

Objective To observe the clinical curative effect of drug combined with psychological treatment on patients with sleep disorders after stroke.Methods A total of 180 cases of eligible patients with sleep disorders were included and randomly di-vided into control group and treatment group.Control group were treated with conventional vascular drug(estazolam,2 mg,before sleep);treatment group increased anxiolytic and sedative hypnotic drugs(venlafaxine,dexzopiclone)compared to control group.Af-ter 14 days,sleep quality,NIHSS were compared both within the treatment group and between the two groups.Results The Bar-thel index,NIHSS and PSQI of two groups had significant differences,and those index of treatment group before and after treat-ment had significant differences too(P <0.05).Conclusion Combined conventional cerebrovascular drugs with Venlafaxine,dexzo-piclone as well as psychological treatment significantly improved sleep quality of patients with acute stroke.

Objective:To investigate the role of planning risk volume (PRV) in estimating the radiation dose for various cardiac substructures (CS). Methods:The CS of 23 patients with left-sided breast cancer who underwent postoperative intensity-modulated ra-diotherapy (IMRT) was delineated. PRV was expanded from CS with an additional margin determined by the mean amplitude of cardi-ac motion. Two IMRT plans were designed. The volume, mean dose, maximal dose (D2%), and standard deviation of CS and its PRV were calculated. Results:In comparison to the volume of CS, the PRV of the heart, specifically the left ventricle, increased by 50%to 80%, whereas the PRV of the main coronary arteries and sub-branches increased by 18.7 times to 42.6 times. In the two IMRT plans, the mean dose to the heart, anterior myocardial territory, anterior descending artery, and their corresponding PRVs ranged from 9.4 Gy to 11.4 Gy, 11.0 Gy to 17.5 Gy, and 22.6 Gy to 27.8 Gy, respectively. The D2%to CS and its PRV was 24.5 Gy to 36.2 Gy, 28.2 Gy to 38.8Gy, and 36 Gy to 45 Gy. The mean dose and D2%to the coronary arteries, including both left and right main coronary arteries, right marginal artery, and left circumflex artery, were 8.6 Gy to 14.9 Gy and 12.5 Gy to 23.7 Gy, respectively. The difference of the mean dose and D2%to CS and its corresponding PRVs was 2.5%to 12.5%and 8.0%to 43.1%, respectively. Compared with the stan-dard deviation of the radiation dose to CS, majority of the standard deviation to PRVs increased significantly. Conclusion:The radia-tion dose difference between CS and its corresponding PRVs is<12%.

Methods Immunohistochemical techniques were adopted to study the expression of bag-1 in ICC tissue ( n=48) and para-hepatocarcinoma bile duct ( control group, n=25). Results Expression of bag-1 in the ICC group was significantly higher than that in the control group. In the ICC group (P

Photobiomodulation therapy (PBMT) is the use of red or near-infrared light to heal, restore, and stimulate physiological processes that repair damage caused by trauma or a disease. PBMT is widely used in sports injuries, arthritis, neuropathic pain, and back and neck pain. In recent years, PBMT is a safe and effective tool for toxic reactions associated with cancer treatment, such as oral mucositis in patients undergoing chemo-radiotherapy for head and neck cancer or stem cell transplantation, radiation-associated dry mouth, taste disorders, radiation dermatitis, post-radiotherapy fibrosis, and lymphedema associated with head and neck cancer and breast cancer. However, the equipment and optimal dosimetric parameters for PBMT have not been fully defined and need to be further explored.

Objective To study the toxicity and efficacy of induction chemotherapy followed by concurrent cisplatin chemotherapy and three dimensional conformal radiotherapy (3DCRT) for inoperable locally advanced non-small cell lung cancer (LA-NSCLC). Methods Totally 76 patients with LA-NSCLC received two cycles induction chemotherapy followed by 3DCRT with a median dose of 68 Gy (64 to 74 Gy).During the 3DCRT, cisplatin (25 mg/m2, weekly) was given intravenously for 6-7 times. Results The CR rate, PR rate and overall response rate of induction chemotherapy were 3% ,42% and 45%. After the concurrent chemoradiation, the corresponding figures were 10%, 62% and 72%. The median survival time (MST) and median progression-free survival (PFS) of all patients were 16.6 months and 10.3 months. The 1-, 2- and 3-year overall survival (OS) and PFS rates were 67% , 35% , 21% and 42% , 15%, 6%. Of patients with stage ⅢA and stage ⅢB disease,the MST were 19.7 months and 15.6 months, the PFS were 10.8 months and 9.4 months. The major treatment-related toxicities included radiation esophagitis, radiation pneumonitis, nausea ( or vomiting) and leukopenia. The major pattern of treatment failure was distant metastasis. Forty-five patients (59%) experienced the local recurrence or/and distant metastasis, including 4 (9%) with in-field failure, 38 (84%) distant metastasis and 3 (7%) malignant pleural effusion. Conclusions Induction chemotherapy followed by concurrent weekly cisplatin and 3DCRT for inoperable locally advanced NSCLC results in encouraging outcomes and acceptable tolerance.

Objective: To investigate the expression of BRCA-associated protein 1 (BAP1) in malignant mesothelioma, non-small cell lung cancer and carcinosarcoma, and its application in the differential diagnosis. Methods: Twenty-two cases of malignant mesothelioma including 17 epithelioid type, 2 sarcomatoid type and 3 biphasic type were collected.As the study control, 80 non-small cell lung cancers infringement pleural membrane(including 40 lung adenocarcinomas and 40 lung squamous cell carcinomas) and 15 carcinosarcomas were included. BAP1 expression was detected using immunohistochemical method. A differential diagnosis antibody panel, including calretinin, WT1, CK5/6, D2-40, CAM5.2, CEA, TTF1, Napsin A, p63 and p40 was tested in all cases. Results: All 80 cases of non-small cell lung cancer and 15 cases of carcinosarcoma were BAP1 positive. In contrast, 64% (14/22) of malignant mesotheliomas lost BAP1 expression (P<0.01). Addition of BAP1 to the mesothelioma marker panel, the diagnostic accuracy of malignant mesothelioma was enhanced to 93%. Focal expression of BAP1 in tumors suggested multiclonal evolution of mesothelioma. Conclusions Loss of BAP1 expression helps to confirm the diagnosis of malignant mesothelioma whereas all non-small cell lung cancer expresses BAP1. It is therefore recommended that BAP1 can be used in conjunction with other immunohistochemical markers to improve the diagnostic accuracy of malignant mesothelioma.

This research work was aimed to improve the performance of magnetic induction tomography (MIT) system by designing a high-performance excitation source and the optimal excitation coil. A new type excitation source with adjustable output was designed, and then the power circuit was simulated by the software ICPA. Focused and solenoid coils were designed in accordance with the design principle of coil, then the optimal excitation coil was proved by measuring the magnetic field distribution and the experimentation of phase detection using neuron cell models. At the stated excitation frequency, the parameters of the excitation source are output power 0.035 W-31.4 W, steady output peak current over 1 A, frequency stability 10(-9), and THD amplitude less than -51dB. When compared with other coils, the focused discal excitation coil is most effective for phase detection with the use of neuron cell models. The excitation source can produce the stated frequency sine wave with higher frequency stability, lower THD and wider adjustable output power. The phase difference between normal cell model and edema cell model was more significant by measurement using focused discal coil.
