Objective To analysis the flash electroretinogram (FERG) of diabeic retionpatby patients. Method 90 cases of DR patients were selected. According to the partial signs and the overall symptoms, the patients can be divided into three syndromes - dry heat by yin deficiency, deficiency of both qi and yin, deficiency of yin and yang. FERG were detected. Result There was close relation between the occurrence and development of DR and the evolution of the syndrome from yin deficiency to yang involved by deficient yin. Retina actional potential will change along with the change of syndrome. Conclusion The retina actional potential which recorded by FERG can be used as an objective criterion of syndrome differentiation, thus we can establish a diagnosis and treatment system of DR.

Objective To evalute the indication and clinical application value of microwave abla-tion in spleen-preserving surgery in treament of patients with traumatic rupture.Methods The clinical data of 45 patients with traumatic splenic rupture were retrospectively analyzed.Spleen preserving surgery was feasible by preoperative CT evaluation and intraoperative observation.36 patients received simply mi-crowave ablation,and 9 cases received microwave ablation assisted partial splenectomy.Postoperative com-plications were observed,and the changes of platelet in peripheral blood were detected before and after op-eration in the 3 th,7th,14th day to evaluate the function of spleen.Results 15 patient was complicated with left pleural effusion,1 patient was complicated with splenic fossa fluid associated with infection.Dur-ing the follow-up of at least 2 months,No patients had postoperative bleeding,hemoglobinuria,gastrointes-tinal leak,deep vein thrombosis and pancreatic leak complications,no deaths.Seven days after microwave ablation spleen-preserving surgery,blood platelet count were significantly higher than the levels before the operation (P <0.05)in spleen-preserving patients.Platelets were no statistically significant after operation in the 3 th,14thday compared with the preoperative(P >0.05).The CT scan and the ultrasonic examina-tion that reviewed after operation in the 30-60th day showed good in spleen imaging in spleen-preserving patients,No patients had portal vein thrombosis.Conclusion Microwave ablation spleen-preserving sur-gery in the treatment of partial traumatic splenic rupture will be a safe and effective operation which could expand the spleen-preserving indication and be used in clinical practice.

Objective To study the hypoxia-inducible factor-1α (HIF-1α) expression in the col-lagen induced arthritis(CIA) model and its role in rheumatoid arthritis (RA) pathogenesis. Methods We established CIA model, and taked CIA model of the ankle joint to have them HE staining and HIF-1α immu-nohistochemistry staining, then the HIF-1α expression in the tissues of RA was observed. Results The ex-pression of CIA synovial membrane of rat and the lower synodal both was expressed in HIF-1α. The positive expression of HIF-1α reached the highest volume in the first 21 days. Then, with the disease progression, the expression gradually decreased, which was in significantly positive relation with the synovial pathology score, synovial hyperplasia and angingenesis rating score, however, the expression was no positively correla-ted with the inflammatory infiltration. Conclusion The expression of HIF-1α in RA tissue is positively re-lated with inflammation severity, It indicates that HIF-1α is closely related to the occurrence and develop-ment of RA.

Objective To evaluate the effect and patient 's tolerance on late-course high-dose radiotherapy (LCHDRT) combined with concurrent chemotherapy for locally advanced non-small cell lung cancer (NSCLC).Methods 73 NSCLC patients were entered into this study from May 2000 to May 2006.The treatment regime consisted of conventional radiotherapy first (40 Gy,20 f,4 w),followed by LCHDRT (24-30 Gy,6 f,2 w,tumor α/β =10 Gy,BED =81.6-93 Gy) combined with concurrent chemotherapy.Conventional irradiation field encompassed the primary lesion,hilum of lung and mediastinal lymph drainage region.LCHDRT focused on the primary lesion only,with ≥95 ％ isodose curve covering the planning target volume (PTV) and the target dose was prescribed to PTV.Supraclavicular metastases lymph node was treated by 6 MV X-ray and electron beam to a total dose of 65-70 Gy.Chemotherapy regime consisted of vinorelbine (25 mg/m2,d1,8 iv) and cisplatin (30 mg/d,d1-3,iv gtt) in the lst and 5th weeks.Results Leukopenia and radiation-induced pneumonitis,as shown by the WHO staging system were the most common acute toxicities.In V20≤25 ％,17.2 ％ (5/29) patients happened radiation-induced pneumonitis only.But in V20 ＞ 25 ％ and ≤ 30 ％,65.9 ％ (29/44) happened radiation-induced pneumonitis (x2 =16.63,P ＜ 0.01).It showed that patients accompany increment of V20,the happening rate of radiation-induced pneumonits probability was increased.The other acute toxicities such as nausea,fever,radiation-induced esophagitis,hemoglobin decrease and thrombocytopenia were mainly grade 1 or 2.After symptomatic treatment,all patients completed the planned treatment without interruption except 4 patients above 70 old years of grade 3 radiation-induced pneumonitis.Late lung radio-fibrosis was 34.3 ％ (25/73).Before the end of the second month after treatment,the complete response (CR) and partial response (PR) rates were 17.8 ％ (13/73) and 69.9 ％ (51/73),respectively,with CR+PR rate of 87.7 ％.The 1-,3-,5-year local control and overall survival rates as monitored by the x2 test method were 82.2 ％,60.3 ％,50.7 ％ and 57.5 ％,23.3 ％,13.7 ％,respectively.Conclusion LCHDRT combined with concurrent chemotherapy shows a promising results,but the rational time-dose-fraction model still need further observation.

Objective To observe the changes in the transforming growth factor-beta 1 (TGF-β1 ) mRNA expression in the lung in a dog model of cardiopulmonary bypass(CPB)-induced acute lung injury. Methods Thirty-six healthy adult mongrel dogs of both sexes weighing 15-16 kg were randomly assigned into control group and CPB group ( n = 18 each) . Lung injury was produced by CPB according to the method described by Williams. Six animals were killed at each of the following time points: before CPB (T0 ) and 30 and 60 min after termination of CPB (T1 , T2) in each group. Lung specimens were obtained for microscopic examination and determination of TGF-β1 mRNA expression (by RT-PCR) and MDA content. The lungs were lavaged and the protein concentration in the brancho-alveolar lavage fluid (BALF) was determined and pulmonary permeability index (PPI) was calculated. Results Microscopic examination showed massive inflammatory cell infiltration, alveolar capillary dilatation, congestion, widened alveolar septum, massive RBC in the alveolar space and focal atelectasis in the lung in CPB group. The TGF-β1 mRNA expression and MDA content and PPI were significantly higher in CPB group than in control group. The TGF-β1 mRNA expression and MDA was positively correlated to PPI (MDA: r = 0.867, P < 0.01; PPI: r = 0.821, P < 0.01) . Conclusion TGF-β1 mRNA expression in the lung is significantly up-regulated after CPB and is an important factor contributing to CPB-induced acute lung injury.

At present, the research regarding repair of spinal cord mainly focuses on tissue engineering. Neural tissue engineering materials provide three-dimensional template for tissue regeneration and also environment for synthesis of extracellular matrix. This paper summarizes the types of nerve transplant materials and the research progress in application for treatment of spinal cord injury, so as to provide theoretical evidence for repair of spinal cord injury. But some problems exist in application of nerve cell scaffold materials for repair of spinal cord injury: poor mechanical properties lead to slow degradation speed, causing difficulties in tissue reconstruction with respect to velocity and in subsequent reconstruction of porous three-dimensional scaffold. In recent years, novel biomaterials with specific repair function have been made by the engineering method through combining the biological molecule with specific signal identification function and available materials, which is an advanced projeot in the current field of biomaterials.

Objective To investigate the effect to the blood supply of the gastrocnemius if ligating the medial or lateral artery, and provide theory base for the sural artery flap repairing the soft tissue defects of legs injuries.Methods The anatomical study involved 16 fresh adult cadaver lower legs ligating the medial or lateral gastrocnemius vessel, the arteries of which were perfused with the Meglumine Diatrizoatis Mucilage,and then carried out the cross-sectional analysis of the CTA, the bifurcation, location length, diameter and perforator of the sural artery were recorded by dissection.To observe the anastomosis with gastrocnemius vessel in artery pipeline foundry made by 1 specimen.Results The consistent with the result of the angiography was the gastrocnemius can completely get enough blood supply from some anastomotic arteriole when ligating one side of the sural vessel.Under normal circumstances, the blood supply of gastrocnemius muscle mainly supplied by sural artery.In the case of the sural vessel was cut off, the blood supply of gastrocnemius come from the anastomotic arteriole between medial and lateral artery and the soleus.The anastomotic arteriole from soleus has larger diameter, but less quantity, and was invariably deteced in the lower third of the gastrocnemius muscle constantly.A lot of anastomotic arteriole were found between the muscle heads, and it was also invariably deteced in the lower third of the gastrocnemius muscle, communicating with the surai neurovascular axis, the average external diameter was less than 0.5 mm.Conclusion The blood supply of the gastrocnemius are enough when ligating the medial or lateral artery.
