Objective To study the expression and significance of indoleamine-2,3-dioxygenase(IDO)in non-small-cell lung cancer(NSCLC).Methods Thirty-eight cases of lung cancer tissues and 10 cases of paracancerous normal lung tissue were collected.The semiquantitative immunohistochemistry was used to detect the positive rate of IDO and fluorescent quantitative PCR to detect the level of IDO mRNA in the lung tissues respectively.Results The positive rate of IDO and the level of IDO mRNA in NSCLC group were significantly higher than in paracancerous normal lung tissues(P＜0.05).There was no significant difference in the positive rate of IDO and the level of IDO mRNA between the adenocarcinoma group and the squamous cell carcinoma group(P＞0.05).Statistically,there was significant difference in positive rate of IDO and the level of IDO mRNA among low,middle and high differentiation groups(P＜0.05).There was significant difference in positive rate of IDO and the level of IDO mRNA between the lymph node metastasis and non-metastasis groups(P＜0.05).Conclusion The high expression of IDO in NSCLC is correlated with the degree of differentiation and the metastasis of lymph nodes,but not with the pathological types.

Objective To find out if different doses of melatonin have different roles in the cause or treatment of idiopathic scoliosis, and to illuminate whether melatonin can be a substitution in the treatment of pinealectomized chickens. Methods Fifty Little-Shaoxing chickens, in which pinealectomy was performed when 3-day-old, were divided into five groups. Ten served as control group, were kept in light-dark (12h: 12h) cycle, 500 lx in daytime and 0-5 lx in nighttime after surgery. Ten served as M-5 group, were given 5 mg/kg (5 milligrams per kilogram of body weight) melatonin twice every day. Ten as M-10 group, given 10 mg/kg melatonin abdominally twice every day, ten as M-20 group, given 20 mg/kg melatonin twice every day, and ten as M-40 group, given 40 mg/kg melatonin twice every day. The light-dark (12h: 12h) cycle was the same as control group. Radiological examinations were performed on all chicken spines for scoliosis when at 3 months old. Measured of the angle of the scoliosis was taken by Cobb's technique, and the data was analyzed by statistical software. Results Overall, there was 25 chickens developed to scoliosis in all when the chickens were 3 months. The attack rate was only 56%; this rate was consistent throughout all experimental groups. In the control group, 6 chickens had obvious scoliosis, and 5 in M-5 group, 5 in M-10 group, 4 in M-20 group, and 5 in M-40 Group. And the average Cobb's angle of control group was 26.7?. There were 23.5?, 21.7?, 24.5? and 23.2? in M-5, M-10, M-20 and M-40 respectively. There was no statistical significance in the average Cobb's angle and the incidence of scoliosis among all groups. It was determined that neither the prevalence nor the pattern of the scoliosis was affected by the therapy in any of the experimental groups. Conclusion Different dose of melatonin can't reduce the rate of scoliosis in the pinealectomized chickens, and also can't prevent the development of the experimental scoliosis. The results of this study raise doubts regarding the role of melatonin in the development of scoliosis after pinealectomy in the young chicken. Melatonin acting as a vicarious therapeutic tool in the treatment of idiopathic scoliosis is premature, deserved further research.

[Objective] To introduce a method of arthroscopic synovectomy in chronic synovitis of the knee in patients with hemophilia A and to evaluate its clinical value.[Method]Arthroscopic synovectomy was performed in 25 patients with hemophilia A from Sept.2002 to Jan.2007.Sufficient factor replacement was used and systematic rehabilitation exercise was emphasized.HSS scores were used to evaluate the efficiency of the operation.Insall standard was used to determine the difference between groups according to Outerbridge grading of the cartilage.[Result]Twenty-three patients were followed up.The mean period of follow-up was 27 months.The average frequency of hemarthrosis reduced from 23.4 times per year preoperatively to 9.8 times per year postoperatively(P

[Objective]To compare the changes in femoral bone tunnel after arthroscopically assisted hamstring ACL reconstruction with different graft fixations and investigate the relation with clinical effect.[Method]Eighty-eight cases in three groups were included and underwent hamstring ACL reconstruction with different femoral graft fixations for average 16.5 months follow-up evaluation.Twenty-six cases in group A received Endobutton fixation,twenty-two cases(group B) received interference screw,and forty cases(group C)received Rigidfix system.Femoral bone tunnel diameters at the articular line level,the widest point,1 cm away from tunnel aperture on sagittal MRI were compared at one week postoperatively.Lysholm score was used to evaluate the clinical effect.[Result]Tunnel enlargement after ACL surgery was noted in the three groups.At the femoral widest point and 1 cm away from tunnel aperture,the tunnel enlargement was larger in group B and smaller in group C.At the femoral articular line level,the bone tunnel enlargement in group C was smallest.There was no difference between those of groups A and B.The shape of femoral tunnel was lineal in groups A and C,and conical in group B.No significant difference was found by Lysholm score.[Conclusion]The type of graft fixation is a major factor in the development of tunnel enlargement after ACL surgery.No correlation between graft fixation,bone tunnel enlargement and clinical effect has been found.

By studying the varieties of peony and analyzing the prescription of Huangqin decoction, the authors explored the differences between Paeoniae Radix Alba and Radix Paeoniae Rubra in varieties, origin, processing method and clinical efficacy and compare their efficacies to define Paeoniae Radix Alba or Paeoniae Radix Rubra in Huangqin decoction recorded in Treatise on Febrile Diseases. In the study, the authors clarified the development and change of the variety in various historical periods according to the earliest ancient herbal book recording the variety and the development sequence of main herbs, and made clear the relations between Paeoniae Radix Alba and Paeoniae Radix Rubra. The modern application of Paeoniae Radix Alba started in the Song Dynasty. Although it was processed in different ways from Paeoniae radix Rubra, they shared the same original plant varieties. On the basis of the historical origin, botanical origin, producing place and processing method, the authors made clear the evolvement of peony varieties, discussed and analyzed the developments and changes for the combined to the separate administration of Paeoniae Radix Alba and Paeoniae Radix Rubra and defined the peony variety in Huangqin decoction. Through the textual research on ancient herbal books, the authors confirmed that more than 2 000 years ago, Paeoniae Radix Alba didn't appear when Treatise on Febrile Diseases was written. According to the records in Miscellaneous Records of Famous Physicians that "its roots were collected and dried in February and August", it was inferred that the use of Paeoniae Radix Rubra conformed to the historical facts.

Objective To summarize the experience of diagnosis and treatment of iatrogenic injury by ureteroscopic surgery.Methods Retrospective analysis of 13 cases with iatrogenic injury by ureteroscopy from December 2008 to December 2011,including 8 men and 3 women,aged 15 to 75 years.Among the 13 cases (Holmium laser lithotripsy under ureteroscope),there were 5 cases of ureterostoma severe disruption,4 cases of submucosa injury,2 cases of perforation,1 case of disruption,and 1 case of sleeve exfoliation of mucosa.Results Among these 13 cases with iatrogenic injury by ureteroscopy,10 cases underwent double J drainage (drainage duration:60 days),and 3 cases underwent open surgery immediately.There was no hydronephrosis when examined by IVU after six months to two years follow-up.Conclusions The skills and techniques of surgical operation should be improved when performing ureteroscopic operation,and it is essential to be familiar with ureteric dissection and alignment,which can avoid ureteric injury.Indwelling D-J tube is very important in dealing with mild ureteral injury secondary to ureteroscopes.Surgical intervention should be given to severe cases of ureteric injury in time.

In order to investigate the effect of Polo-like kinase-1 (Plk1) depletion on cell cycle progression and cell growth in lung cancer cells, a recombinant plasmid containing antisense RNA targeting Plk1 (pcDNA3-Plk1) was transfected into A549 cells by lipofectine. RT-PCR and Western-blot were used to detect the Plk1 gene expression. Cell proliferation was evaluated by direct cell counting and bromodeoxyuridine (BrdU) labeling. Cell cycle distribution and apoptosis were examined by flow cytometry, and the inhibition rate (IR) by vinorebline (NVB) was determined by MTT assay. The results showed that after transfection of pcDNA3-Plk1 into A549 cells, the expression levels of Plk1 mRNA and protein were greatly decreased. In pcDNA3-Plk1 transfected groups, abnormal morphological changes of cells and growth inhibition were observed, and the BrdU labeling index was significantly lower than in the control groups (P<0.05). Cells in pcDNA3-Plk1 transfected groups were arresed in G2/M phase and apoptosis was detectable 72 h post transfection. IR induced by vinorebline in pcDNA3-Plk1 transfected groups was significantly higher than in other groups. These data suggested that antisense RNA targeting Plk1 could suppress the Plk1 expression, and therefore, significantly inhibit cell proliferation and induce cell cycle arrest and apoptosis. Moreover, it sensitized lung cancer cells to chemotherapy.
