Objective To explore the effect of microsurgery for refractory temporal lobe epilepsy . Methods A retrospective analysis was made in 102 patients with refractory temporal lobe epilepsy from January 2005 to December 2011.The patients received comprehensive preoperative localization , intraoperative frontotemporal pterional incision , and microsurgical resection of epileptogenic focus .The efficacy was evaluated according to the Engel standards .Indications such as self-care ability, learning ability, and working ability were used to evaluate the quality of life , which were recorded and compared before and after operation . Results Follow-up was accomplished in all the 102 cases for a duration of 1 year and 9 months to 7 years.There were no mortality and serious complications .The effects evaluations at 1 year after operation showed complete disappearance of symptoms ( levelⅠ) in 61 cases (59.8%), almost disappearance (level Ⅱ) in 17 cases (16.7%), symptoms improvement more than 75% (level Ⅲ) in 13 cases (12.7%),and ineffective (level Ⅳ) in 11 cases (10.8%), bearing an effective rate of 89.2% (91/102) and a good-and-excellent rate of 76.5%(78/102).At one year and nine months postoperatively , 6 patients could not take care of themselves , 32 patients obtained partial self-care, and 64 patients had complete self-care,as compared with which there were 21 patients, 67 patients, and 14 patients preoperatively, respectively, having significant differences before and after surgery (Z =-7.001, P =0.000). Statistical significances were obtained before and after operation in 67 cases of children and adolescents with learning ability ( Z=-3.747, P =0.000) and in 35 adult cases with working ability ( Z =-2.564, P =0.010). Conclusions Microsurgical treatment is an effective method for refractory temporal lobe epilepsy .Patients ’ quality of life can get significant improvement after surgery.

Desmoid tumor also known as aggressive fibromatosis,are rare fibroblastic tumors which are derived from deep fascia planes or muscuofascia structures.Resectable extra-abdominal and abdominal desmoid tumor should always be treated with the aim of achieving a negative margin through wide radical resection with margins above 2 cm.Ifthis is not feasible,function-sparing surgical resection is suggested.Adjuvant radiation should be considered for patients with positive margins,recirrent tumors or unresectable diseases.Intra-abdominal desmoid tumor is common in patients with familial adenomatous polyposis.It has a high recurring rate after surgical resection and therefore a high dosage of tamoxifen and sulindac are recommended as first-line treatment.Due to the variable nature of the outcome and vague reaction to drug therapy,individualized treatments,including the wait and see policy,has been widely investigated and thought to be a promising strategy for the future.

Objective: To compare the expression levels of FOXP3 mRNA in the peripheral blood mononuclear cells(PBMC) of hepatitis B patients and healthy persons.Methods: Real-time fluorescence relative quantitative RT-PCR was used to determine the FOXP3 mRNA levels in the PBMCs from 25 patients with chronic hepatitis B and 11 healthy subjects.Results:The FOXP3 mRNA levels were significantly higher in the hepatitis B patients than in the normal subjects(P0.05).Conclusion: The high expression of FOXP3 might be an important factor for the persistence of HBV infection.

Objective To explore expression of Beclin1, autophagy-related protein 1 (Atg1), mammalian target of ra-pamycin (mTOR) in squamous cell carcinoma (SCC) and adenocarcinoma of lung and to analyse relationship among these three factors. Methods Immunohistochemical stainning was applied to detect expression of Beclin1, Atg1 and mTOR in 82 samples of SCC and adenocarcinoma of lung (lung cancer group) and 17 samples of paraneoplastic normal lung tissues (con-trol group). Correlations of expression of Beclin1, Atg1 and mTOR were analyzed in SCC and adenocarcinoma of lung. Re-sults The expression of Beclin1 was significantly lower in lung cancer group than that in control group(52.44%vs 94.12%, P＜0.01). There were significant differences of the differentiation, TNM stages and lymph node metastasis in lung cancer group compared with those in control group. And Beclin1 expression showed a decreasing trend with malignant and invasive of tumors. mTOR expression in lung cancer tissue with lymph nod metastasis is higher than that in the tissue without lymph node metastasis(P＜0.01). Atg1 expression in lung cancer tissue with larger mass is less than that in lung cancer tissue with small lumps(P＜0.01). Beclin1 Expression was positively correlated with the Atg1 expression in SCC(r=0.609,P＜0.01). Beclin1 and Atg1 expressions were both negatively correlated with mTOR expression in SCC(r=-0.617,-0.444,P＜0.01). Beclin1 expression was positively correlated with Atg1 expression in adenocarcinoma(r=0.458,P＜0.01). Beclin1 and Atg1 expression were both negatively correlated with mTOR expression in adenocarcinoma(r=-0.497,-0.541,P＜0.01). Conclu-sion Beclin1, Atg1 and mTOR expression showed a strong correlation in lung cancer, and clinicopathological change of lung SCC and adenocarcinoma may be related to autophagy.

Objective:To investigate the Prostaglandin E2(PG-E2),Leukotrienes B4(LT-B4)、Platelet activating factor(PAF) and vascular endothelial growth factor (VEGF) levels in the model of UC rats serum,and the changes after the Mesalazine,clostridium, and montmorillonite powder treatment intervention ,in order to understand the significance of the four inflammatory factors in UC rats and the interference effect of the above three drugs on the four inflammatory cytokines .Methods:100 rats were randomly divided into normal group(A),model group(B),Mesalazine group(C),clostridium group(D)and montmorillonite group(E),The levels of the plasma PG-E2,LT-B4,PAF and VEGF were measured by ELISA .The different changes of the four cytokines were compared in the different groups.Results:①The scores of DAI and the levels of the plasma PGE2,LTB4,PAF and VEGF in the B,C,D and E group were higher than ones in A group(P<0.05).②Compared B group,the scores of DAI and the levels of plasma PGE2,LT-B4,PAF and VEGF in B,C,D and E group were lower ( P<0.05 ) .③Compared the efficacy among mesalazine , clostridium and montmorillonite powdergot treating UC , mesalazine and montmorillonite powder got the best results ( P<0.05 ) .The efficacy between mesalazine and montmorillonite was similar.Conclusion:①The PGE2,LT-B4,PAF and VEGF are very active higher in the blood of rats with UC and have a positive correlation with inflammation .②Mesalazine, clostridium and montmorillonite powder may renovate the damage of inflammatory tissues of rats with UC , and relieve the symptoms of inflammation , and also shorten the duration of inflammation by reducing exudation of proinflammatory cytokines PGE 2,LTB4,PAF and VEGF.

Objective To analyze the typical and atypical X-ray findings and improve the understanding of the atypical features of breast cancer . Methods The mammographic manifestations of 61 patients with breast cancer were retrospectively analyzed . Results The X-ray findings were as follows: mass (n=39); microcalcification (n=30);localized tortuosity or disturbance of mammary gland architecture (n=4), star sign (n=3),asymmetrical and localized increased density (n=3) without mass and/or microcalcification.Conclusion Mass and microcalcification are very important and typical signs for diagnosing breast cancer, but some atypical X-ray findings can be found, including: localized disturbance of mammary gland architecture, star sign, asymmetrical and localized increased density, sometimes one of these X-ray findings is the only sign of malignancy. To recognize atypical X-ray findings of breast cancer is valuable for improving diagnostic rate.
