Objective:To evaluate the effect of radiotherapy combined with neoadjuvant chemotherapy on patients with upper esophageal carcinoma.Methods:Forty-five patients with upper esophageal carcinoma were divided into two groups randomly. There were 23 patients in neoadjuvant chemotherapy plus radiotherapy group(CR),and 22 patients in radiotherapy group(R).The regimen of neoadjuvant chemotherapy including cisplatin and 5-fluorouracil was administered.Two to three weeks after two cycles of chemotherapy,the patients were irradiated.Carmofur in CR group was administered in the period of late-course radiotherapy for four weeks,and the methods of radiotherapy were identical in two groups.Results:The 1,2,3-year survival rates were 73.91%,56.52% and 47.83% for CR group and 59.09%,31.82% and 18.18% for R group,and survival rates differed significantly(?2=4.8112、P =0.0283)in two groups;however,more serious side effects were in CR group,but they could be tolerated by patients.Conclusions:Neoadjuvant chemotherapy with PF regimen plus radiotherapy may improve the outcome of upper esophageal carcinoma.

Objective To Search for the induced factors and therapeutic strategies for ovarian hyperstimulation syndrome(OHSS).Methods 38 cases with OHSS were retrospectively analyzed.Results All cases had symptoms of stomach and intestine,hcmachrosis and ascitic fluid.Human serum albumin through intravenous dripping was one of the most successful treatment as plasma expanders through restoration of effective blood volume.Paracentesis was necessary for critical OHSS patients with severe ascites and hydrothorax.Herus could decrease the cost of albumin significantly.Conclusions OHSS was the severe complication of ovarian stimulation.All patients with OHSS got completely recovered through intense care and effective treatment.

Specific activation of toll-Like Receptor 9 (TLR9) by ligand CpG DNA/ODN can initiate downstream signaling.The activation of TLR9 signaling is regulated by Granulin,high-mobility group box-1 (HMGB1) and soluble TLR9.Interestingly,TLR9 is no longer only presented in the immune cells,but also expressed in many kinds of tumor cells.TLR9 is involved inmaintaining and promoting the malignant biological behaviors of tumor cells.Elucidation of the function of TLR9 inherent signaling pathways in the tumor cells will provide a novel idea for oncotherapy.

AIM:To optimize the processing parameters of Semen raphani by uniform design. METHODS:In order to compare the change of Semen raphani in quality before and after simple stir-frying,allyl glucosinolate was selected as the internal standard. The relative content of glucosinolate was determined by HPLC and the processing parameters were optimized. RESULTS:The glucosinolate content gradually decreased as the processing time increased,maxima in HPLC peak area appeared at 200-250 ℃ and in the range of 1-1. 5 min and the content of glucosinolate in the processed Semen rahani was 4. 2 times as great as that in the non-stir-frying. CONCLUSION:It shows that the optimized processing of Semen raphami is beneficial for the conservation of glucosinolates.

The idiopathic macular hole ( lMH ) is research priority associated with the regenerate quickly of vitrectomy. The unaided visual acuity and the best corrected visual acuity is partial for the visual acuity of the patient with lMH. The mechanism and clinical significance of modern visual function measurements associated with lMH, including contrast sensitivity, visual field, multifocal electroretinogram, and stereoscopic vision, have been introduced. These measurements could be of great value in early diagnosis of lMH, assessment of surgical indication and evaluation of visual performance after vitrectomy. They would also be helpful to the analysis of postoperative impaired visual function and its management. Having an adequate understanding of the contents and significance of visual function is helpful to the improvement of lMH surgery techniques and postoperative visual acuity.

Aim The pharmacokinetic parameters and relative bioavailability of capsule A(Maiwei Pharmaceutical Co Ltd, Beijing, China) and capsule B (Xianjing Pharmaceu-tical, Hunan, China) were studied. Methods A single oral dose of 600 mg gemfibrozilof these two kinds of capsules was given to 12 chinese healthy male volunteers in anopen, randomized crossover study. Plasma levels were determined with HPLC-UVmethod. Results The plasma concentration-time curve was fitted to 1-compartmentopen model with a first order and lag time absorption and the major pharmacokineticparameters of capsules A and B were shown respectively as following: C max(32. 69?5. 67 )and (29. 41?2. 60) mg?L-1; Tmax (1. 01?0. 14) and (1. 13?0. 37) h, t1/2ka(0. 46 ? 0. 18) and (0. 62 ? 0. 20) h; C max (1. 11 ? 0. 32) and (1. 32 ? 0. 26) h; MRT(2. 14 ? 0.27) and (2. 37 ? 0.26) h; AUC (91.7 ? 13.2) and (82.2 ? 7. 38) mg?h? L-1. There were no significantly differences between the pharmacokinetic parame-ters of capsule A and B. The relative bioavailability of the capsule A was (110 ? 9) % ascompared to the capsule B. Conclusion The two kinds of capsules have the equivalentbiological effects.

Objective To discuss the application value of texture analysis of conventional MRI in differential diagnosis of orbital lymphoma from inflammatory pseudotumor.Methods The conventional MRI data of 15 patients with lymphoma and 17 patients with inflammatory pseudotumor proven by pathology or clinical follow-up were retrospectively reviewed.The texture features of lesions based on axial T1WI,fat-saturated T2WI and contrast enhanced fat-saturated T1WI were extracted by manually drawn ROIs with software MaZda.The subsets of optimized texture parameters were chosen by four different methods:Fisher coefficient,probability of classification error and average correlation coefficient (POE+ ACC),mutual information measure (MI) and the combination of the above three methods (FPM),respectively.Linear discriminant analysis (LDA) and nonlinear discriminant analysis (NDA) were performed for texture classification.The texture features from the sequence with the best classification result of orbital lymphoma and inflammatory pseudotumor were compared.Results The optimal texture parameters were mainly derived from co occurrence matrix and run-length matrix on T1WI and T2WI.The optimal texture parameters were mainly derived from co-occurrence matrix and histogram on contrast enhanced T1WI.The best classification of MRI texture was obtained within T2WI with lowest classification error of 1.56％ achieved by FPM in combination with NDA.Comparing the texture parameters of orbital lymphoma and inflammatory pseudotumor on T2WI,the angular second moment and long length emphasis were significantly higher in orbital lymphoma (both P＜0.005),while the entropy and short length emphasis were significantly lower in orbital lymphoma (both P＜0.005).Conclusion It is feasible to use texture analysis on conventional MRI for the differentiation of orbital lymphoma and inflammatory pseudotumor.

Objective To evaluate the in vitro biological safety of acellular spinal cord scaffold so as to provide theoretical basis for constructing the ideal tissue engineering scaffold of spinal cord.Methods A piece of thoracic spinal cord for 2 cm removed from SD rats was harvested and then was treated by freezing and thawing and chemical extraction with 3% sodium deoxyeholate and 1 KU/ml DNaseI and RNaseA. Gross observation and histological examination of the acellular spinal cord scaffold were carried out to learn the condition of the extracellular matrix scaffold. The biological safety of the acellular spinal cord scaffold was evaluated. Results In cross section, network of the extracellular matrix was presented in the scaffold. The cells, myelin and axons disappeared after the spinal cord was treated with sodium deoxycholate, DNaseI and RNaseA. Typical network of empty tubes were viewed in longitudinal sections. General toxic reaction, pyrogen test, hemolysis test and cytotoxicity test were conforming to the standard of materials. Conclusion As neotype tissue engineering material, the acellular spinal cord scaffold has satisfactory biological safety.

Recent researches show that follicle stimulating hormone (FSH) plays an important regulatory role in the angiogenesis of ovarian cancer by influencing the level of some factors such as hypoxia inducefactor-1 ( HIF-1 ) ,vascular endothelial growth factor (VEGF). Meanwhile, recent studies report that FSH and FSH receptor(FSHR) may also participate in the angiogenesis of other solid tumors like lung cancer. FSH is closely related to the tumor angiogenesis, which provides a novel therapeutic target for anti-angiogenesis thera-py.
