Objective To quantify the incidental irradiation dose (ⅡD) to lymph node stations of esophagus when treating patients with T1-4N0 M0 thoracic esophageal squamous cell carcinoma (ESCC) with a dose of 60 Gy/30f.Methods Twenty-nine patients with medically inoperable T1-4N0M0 thoracic ESCC were treated with three-dimensional radiotherapy on involved-field.The conformal CTV was re-created using a 3 cm margin in the proximal and distal direction (following the course of the esophagus) beyond the barium esophagogram,endoscopic examination and CT defined GTV and a 0.5 cm margin in the lateral and anteroposterior directions of the CT defined GTV.The PTV encompassed 1 cm proximal and distal margins,0.5 cm radiaI margin on the basis of CTV.Cervical,mediastinal and abdominal lymph nodes were delineated respectively.Equivalent uniform dose (EUD) and other dosimetric paraneters were calculated for each nodal station.Nodal region whose metastasis rate is greater than 5% was considered a high risk lymph node subgroups.Results Under a 60 Gy dose prescription,the median Dmean and EUD,V40 and V50 were ≥40 Gy,≥85% and ≥75% in most of the high risk nodal regions.For the subgroups whose EUD were less than 40 Gy,most of the ⅡD of these regions was significantly associated with the length and location of esophageal tumor (r =0.892,P =0.000).Conclusions Lymph node stations nearby of ESCC received considerable ⅡD with involved-field irradiation which could control subclinical lesions.But more clinical studies should be needed.

Two-dimensional electrophoresis(2-DE) is an important technique in proteomics research.The 2-DE system for proteome of Monascus ruber was established by comparing and analyzing the infection caused by different kinds of mediums,lysis buffer and the condition of rehydration.By cultivating the Monascus ruber with YES for 6 days,extracting total protein by TCA-acetone,lysis buffer with 8 mol/L urea,2 mol/L thiourea,4 % CHAPS,1 % DTT and 2 % Bio-lyte,an ideal 2-DE map with higher resolution and better legibility was obtained,which laid a foundation for the further studies on proteome of Monascus ruber.

Objective:To analyze the cause of the blood heat syndrome in psoriasis.Methods: Made the investigation form about information of psoriatic patients through DME method and reference both Chinese and foreign documents,analyzed main component of data by SAS software.Results: The first main component of blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion;the second main component is family history;the third main component is dampness;the forth main component is the allergy to the food;the fifth is outside irritation.Through the corresponding investigation we found that food include hot food,beef,sheep and sea food,emotion problem include over work and stress,dampness include work and living in humid place for long time,outside stimulus meant chemical stimulus.Conclusion: The main cause of the blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion,family history,humidity,allergy to the food and chemical stimulus in order.

Objective To study the effects of Guhong injection on the expression of vascular endothelial growth factor (VEGF) in the cortex 14 days after cerebral ischemia-reperfusion. Methods 30 male Sprague-Dawley rats were divided into sham group (n=6), ischemia group (n=6), aceglutamide injection group (n=6), Honghua injection group (n=6) and Guhong injection group (n=6). The middle cerebral arteries of all the rats were occluded for 2 hours and reperfusion, except the sham group. Drugs were administered once a day 24 hours after reperfusion. The expression of VEGF in cortex was detected with enzyme-linked immunosorbent assay (ELISA) 14 days after reperfusion. Results The expression of VEGF decreased in the ischemia group compared with the sham group (P<0.001), and it increased both in the aceglutamide and Guhong injection groups compared with the ischemia group (P<0.05). Conclusion Guhong injection can significantly increase the expression of VEGF in the cortex 14 days after ischemia-reperfusion, which may be one of the ways for neuro-protection.

AIM:To discuss Daidzein intravitreal injection whether has protective and recovery effects on acute nerve damages.
METHODS:After the crush models of acute optic nerve were set up, 72 males SD rats were divided into 4 groups randomly as common group without surgery, FBS negative control group, Daidzein treatment group ( 10μmol/L, 100μmol/L, 1000μmol/L ) and positive control group using rats nerve growth factor ( mNGF, 100ng/mL ). Three days after interference, all experimental animals were executed. HE staining was used to evaluate morphologic change of the retina, immunohisochemical staining and western-blot tests for identifying and quantifying the distinct expression of Caspase-3 and GAP-43 among the groups.
RESULTS: Compared with the normal group and negative control group, retinal morphology of different concentrations of each Daidzein treatment group and positive control group was more complete, the expression of Caspase-3 protein was relatively lower, the expression of GAP-43 protein was relatively higher, the differences have statistically significance (P<0. 05).CONCLUSION: Daizein injection in the vitreous cavity has the capacity of protection and restoration in rat's acute nerve damages.
