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.

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.

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.

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.

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.

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.

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.

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.

Objective To investigate the expression of CKLF?2 mRNA in rats′ myocardium at different development phase. Methods Total RNA was extracted from fetal rat hearts at day12 and day 18 after coitus, and from new-born rat hearts right after birth, day 3, day 7 and day 21 after birth, as well as from adult rat hearts. The expression of CKLF?2 mRNA was tested by competitive polymerase chain reaction (CPCR). Results Compared with the postnatal myocardium, the expression of CKLF?2 mRNA obtained its peak level in the 12-day-post coitus, which then decreased gradually to a relatively low level until birth. It increased slightly at birth and subsided to the lowest level in adulthood. Conclusion CKLF?2 probably takes part in the procession of the myocardial proliferation and the development of rat′s heart.
