Objective To compare the efficacy of postoperative chemotherapy in combination with radiotherapy and simple radiotherapy in malignant glioma.Methods 82 patients with malignant glioma resection patients were randomly divided into observation group and control group,there were 41 patients in each group.The control were treated with simple three-dimensional conformal radiotherapy.The observation group were given temozolomide chemotherapy on the basis of three-dimensional conformal radiotherapy.The effects and adverse reactions were observed.Results Total effective rate of observation group was 63.4％ (26/41),significantly higher than that in the control group 34.1％ (14/41) (x2 =8.2439,P ＜ 0.01);gastrointestinal adverse reaction rates of the observation group was 100.0％,significantly higher than 58.5％ of the control (P ＜ 0.01),the difference of bone marrow suppression in two groups had no statistically significant (P ＞ 0.05).Conclusion Although with a higher incidence of gastrointestinal reactions,postoperative chemotherapy with radiotherapy have reliable effect,it is worth using in the condition of appropriate and timely symptomatic and supportive treatment.

Objective:To observe therapeutic effect of maleic acid levamlodipine (amlodipine) on inflammatory fac‐tor levels in patients with essential hypertension (EH) .Methods :According to random number table method ,a to‐tal of 84 EH patients were randomly and equally divided into nifedipine group (received nifedipine treatment ) and amlodipine group (received maleic acid levamlodipine treatment ) ,both groups were treated for 12 weeks .Blood pressure ,serum levels of tumor necrosis factor α(TNF‐α) ,interleukin‐6 (IL‐6) and high sensitive C reactive protein (hsCRP) were measured and compared between two groups before and after treatment .Results:Before treatment , there were no significant difference in blood pressure ,serum levels of TNF‐α,IL‐6 and hsCRP between two groups , P>0.05;after treatment ,all above indexes significantly reduced in both groups compared with before treatment ,P<0. 01 all .Compared with nifedipine group ,there were significant reductions in systolic blood pressure [ (136. 9 ± 13.4) mmHg vs . (128.3 ± 12.5) mmHg] ,diastolic blood pressure [ (88.4 ± 7.1) mmHg vs . (82.7 ± 6.8) mm‐Hg] ,serum levels of TNF‐α [ (10.85 ± 2.56) ng/L vs . (8.61 ± 2.37) ng/L] ,IL‐6 [ (18.92 ± 4.61) ng/L vs . (13.73 ± 4.18) ng/L] and hsCRP [ (7.95 ± 2.38) mg/L vs . (5.89 ± 2.24) mg/L] in amlodipine group , P<0.01 all .Conclusion:Amlodipine can more significantly reduce levels of TNF‐α,IL‐6 and hsCRP ,inhibit inflammatory reaction than those of nifedipine and contribute to blood pressure control in patients with essential hypertension .

Objective To analyze the biological characteristics and morphologic features between the mouse models using MDA-MB-231 cells established by injecting tumor cell suspension or implanting tumor tissues. Methods Twenty BALB/c mice were randomly divided into two groups,with 10 in each group.The orthotopic models of breast cancer were established by injection of tumor cell suspension or implantation of tumor tissues in the fat pad of right second breast in the nude mice of the two groups,respectively.The time of tumor formation,success rate,tumor growth rate,shape,central tumor necrosis,blood vessel distribution and tumor ulceration were compared between the two groups of models.The histological features of the tumors were also observed. Results There were no significant difference in the success rate between the two methods.In the group of tumor tissues implantation,the tumors formed in an earlier time with various shape configurations,and they were hypovascular and vulnerable to central necrosis with the resultant superficial ulcerations.However,in the group with injection of tumor cell suspension,the tumors formed later with a regular shape,and the superficial ulceration was rare and not vulnerable to central tumoral necrosis since the tumors were abundant in blood vessels resulting in adequate nourishment.There were no significant difference in the pathological findings between the two groups. Conclusion The nude mouse models of breast cancer can be successfully established by both tumor tissues implantation and tumor cell suspension injection,with identical biological characteristics and fairly different morphological features.The investigators are well advised to choose the more appropriate one according to the purpose of the experiments.

Objective: To provide anatomic data for management of pterygopalatine fossa lesions via endoscopic transnasal approach. Methods: Fifteen (30 sides) formalin-preserved human skulls were subjected to microsurgical dissection to evaluate the exposure scopes of 3 different endoscopic surgery approaches: endonasal middle meatal transpalatine approach, endonasal middle meatal transantral approach, and endonasal inferior turbinectomy transantral approach. Meanwhile, 20 (40 sides) dry skulls were dissected and the related measurements were obtained. Results: The 3 approaches allowed for different exposure of the pterygopalatine fossa structure. The mean distances from foramen rotundum to anterior nasal spur, superior orbital fissure, and optic canal were (61.86±3.67)mm,(3.56±0.75) mm, and (11.23±1.24) mm, respectively. Conclusion: The 3 endoscopic approaches are safe and effective for resection of different pterygopalatine fossa lesions and foramen rotundum serves as a landmark for safe management of the pterygopalatine fossa.
