Objective To evaluate the absorbed doses of lower-neck and supraclaviclar subclinical target and the normal tissues of nasopharyngeal carcinoma using three different intensity-modulated radiation therapy (IMRT) techniques. Methods Three radiotherapy techniques were single tangential low neck-supraclavicular field technique (tech1), seven portal IMRT in which the gantry angles are 180°, 150°, 120°, 90°, 270°, 210°(tech2) and 240°and eight portal IMRT in which the gantry angles are 180°, 150°, 120°,90°,0°,270°,210°and 240°(tech3). The dose distribution of lower-neck and supraclaviclar subclinical target and normal tissues were analyzed through the dose-volume histograms, high dose volumes were analyzed using V60 (volume of accepted > 60 Gy/all volume × 100%). The delivery efficiencies were evaluated by means of the total number of segments and MUs. Results The V60 of PTV2 were 65%, 10% and 3% in tech1, tech2 and teeh3 respectively. The maximum doses of spinal cord were 42.0, 48.9 and 45.1 Gy in techl, tech2 and tech3 respectively. The average doses of trachea were 32.92, 52.17 and 36.56 Gy in techl, tech2 and tech3 respectively. Conclusions Tech1 is simple method, but the dose distribution is very nonuniform. Tech2 is better than the Tech1, but the spinal cord and trachea receive the highest doses in three strategies. Tech3 uses less number of segments and MUs than Tech2, and has the best dose distribution.

Objective To evaluate the feasibility,safety,post-operative short and long-term outcomes of laparoscopic-assisted D2 radical distal gastrectomy in treating advanced gastric carcinoma without serosal invasion.Method From May 2007 to May 2013,54 cases of advanced gastric antral cancer without serosal invasion underwent laparoscopic-assisted D2 radical distal gastrectomy (laparoscopic group),54 demographically and pathologically-matched cases undergoing open surgery served as control.The surgical risk,post-operative recovery and follow-up results were compared.Result Surgery was successful in all patients.The mean operation time in laparoscopic group and open group was (168 ± 31) mins and (157 ±20) min respectively,the difference was significant (t =2.237,P =0.027) ; Intra-operative blood loss was (151 ± 56) ml and (213 ± 86) ml (t =4.45,P =0) ; Post-operative intestinal function recovery time was (2.7 ± 0.7) d and (3.4 ± 0.5) d (t =5.4,P =0) ; Lymph node dissection number was (26.4 ± 4.2) and (24.8 ±5.2) (t =1.769,P=0.08).Post-operative complication rate was 4％ and 11％ (P =0.142).There was no perioperative mortality in either group.Post-operative pathological stage of Ⅰ B,Ⅱ A,Ⅱ B,ⅢA was 8,17,24,5 cases in laparoscopic group and 9,14,23,8 cases in open surgery group.108 cases were followed up from 7 to 79 months.In laparoscopic group,8 cases had local recurrence or distal mestastasis,and 4 cases died from tumor; In open group,9 cases had local recurrence or distal mestastasis,and 6 cases died from tumor.Conclusions Laparoscopic-assisted D2 radical distal gastrectomy in treating advanced gastric cancer without serosal invasion is feasible,safe and advantageous in minimal invasion and rapid recovery,with good short and long-term outcomes.

Objective To evaluate the imaging diagnosis value of glomus tympanicum tumors.Methods Images of 10 patients with surgically and pathologically confirmed glomus tympanicum tumors were reviewed.The image characteristics and diagnostic value were summarized.Results In 8 patients with high resolution CT scan and 2 patients with routine CT scan,soft tissue nodules within the tympanic cavity were identified on axial or coronal images in 7 of them.And in 3 patients with chronic tympanitis,glomus tympanicum tumors were not differentiated on CT images.Eight patients had undergone MR examination,on T2WI the tumors were moderate hyperintense(n=6)and hyperintense(n=2),and the tumors were enhanced obviously after contrast.In 3 patients with chronic tympanitis,moderate high signal of the tumor can be differentiated with the high signal of tympanitis on T2WI.On contrast MRI,the signal of enhanced tumor or unenhanced tympanitis was identified clearly.Conclusion On diagnosis of glomus tympanicum tumors,MRI is prior to CT,especially in patient with glomus tympanicum and tympanitis.

BACKGROUND:Liushen Pil is a traditional Chinese herbal formula, has the effects of heat-clearing and detoxicating, eliminating stagnation, detumescence and al eviating pain. Modern pharmacology verifies that Liushen Pil has anti-inflammatory, analgesic, cardiac, anti-viral, anti-tumor effects, and has been extensively used in the treatment of various infectious diseases and malignant cancer. OBJECTIVE:To investigate the inhibitory effects of Liushen Pil on esophageal cancer xenografts, and effects on microvessel density and vascular endothelial growth factor expression. METHODS:After reproducing nude mouse models of human esophageal cancer, 48 nude mice were randomly divided into high-dose Liushen Pil group, moderate-dose Liushen Pil group, low-dose Liushen Pil group, cisplatin group, model group and blank group. According to medication regimen, drugs were given. The growth of transplanted tumor of nude mice was dynamical y observed in each group. The nude mice were sacrificed after 20 days of treatment. Neoplasm weight was taken and the tumor-suppressing rate was calculated. Immunohistochemistry was used to detect microvessel density and the expression of vascular endothelial growth factor. RESULTS AND CONCLUSION:The weight of transplanted tumor was significantly lower in the high-dose Liushen Pil group, moderate-dose Liushen Pil group, low-dose Liushen Pil group, and cisplatin group than in the model group (P<0.05). Microvessel density and the expression of vascular endothelial growth factor were obviously lower in the each Liushen Pil group than in the model group, but not as apparent as that in the cisplatin group. Results suggested that Liushen Pil can inhibit the growth of the esophageal cancer xenografts. Liushen Pil can down-regulate the expression of vascular endothelial growth factor and reduce microvessel density, which is one of the tumor-inhibiting mechanism of Liushen Pil .
