Objective To observe the therapeutic effect of tumor necrosis factor inhibitor (Etanercept) on intractable ankylosing spondylitis (AS) related hip joint lesion. Methods Thirty-five patients with AS with unilateral or bilateral hip joints pain and limitation of joint motion were included into this study. The patients' conditions were not controlled under standard treatment by non-steroidal anti-inflamma-tory drug and antirheumatic medications. The clinical trial was designed as a prospectiveopen study, 35 pati-ents received Etanercept 50 mg once a week for 12 weeks, combined with methotrexate (MTX) 10 mg once a week. Parameters including Harris hip score, Bath ankylosing spondylitis radiologic index-hip (BASRI-hip), Bath ankyiosing spondylitis disc.use activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), Erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were evaluated and side effects were observed before and after the treatment. Results Fifty-five hip joints were involved in 35 patients, in which unilateral hip involvement in 15 patients and bilateral in 20 patients. Harris score of the hips iner-eased significantly from 51±4 before treatment to 86±5 (P=0.000) after treatment ; Before and after treatment, BASDAI changed from 6.4±1.2 to 4.4±0.8 (P=0.000), BASFI was changed from 6.3±1.1 to 3.4±0.8 (P=0.000), before and after treatment ESR was changed from (68±28) mm/l h to (25±6) mm/l h (P=0.001), CRP changed from (59.1±22.3) mg/l, to (6.9±1.1) mg/L (P=0.000) before and after treatment respectively, but BASRI-hip was not changed obviously before and after treatment. No tuberculosis and serious side effects was observed during the treatment and follow-up period. Conclusion Etanercept, when combined with methotrexate, could be used to treatintractahle AS-related hip joint lesions. This regimen could improve the hip joint function and control the disease activity without serious side effects.

Objective To evaluate the efficacy of ultrasonically guided radiofrequency (RF) thermal ablation of hepatic carcinoma (HC) with a clustered electrode. Methods Clinical records on 245 consecutively admitted HC patients who underwent RF tissue ablation therapy were analyzed. The tumor supplying blood flow, changes of tumor size, clinical manifestation, and AFP level were analyzed. Results AFP value decreased significantly in 50% of patients one week after ablation. Tumors less than 5*!cm in diameter became avascularized 1 to 6 months after the therapy, and it was noted that all tumors shrank in size after the therapy. For tumors more than 5*!cm in diameter, RF ablation was used in conjunction with intraarterial chemotherapy and embolization. Conclusion Ultrasound guided RF thermal ablation is an effective, safe, minimally invasive technique for treating malignant hepatic tumors.

[Objective]Giant cell tumor of bone is notorious for its local aggressive behavior and its tendency to recur after operative treatment.Bisphosphonates is the drug of anti-osteoporosis.It is found also have anti-cancer effect recently.We conducted experiment examing the effect of bisphosphonates alendronate on the growth and survival of the cells.To study if bisphosphonates are capable of inducing cells death and significantly inhibiting their growth in vitro.[Method]Cells viability was detected by MTT Assay after the tumor cells were cured with different concentration and different time.Tumor cells apoptosis with in situ TUNEL assay and flow cytometry was detected.The active Caspase-3 was also detected.[Result]After exposure to alendronate,the cells exhibited the characteristic features of cell shrinkage,rounding and partial detachment,and demonstrated the lobulated appearance of apoptotic cells.It was much more prominent while the treating time prolonged or the concentration increased.Alendronate((5 200) M) treatment for 24 h,resulted in 2.79%~31.17% decrease in cell viability,and 11.13%~49.94% for 72 h,respectively.A significant dose-dependent and time-dependent decrease in the number of viable cells was observed in the GCT cells.After Alendronate treat for 24 h,the mean cell population in apoptosis was 14.32% at concentration 5 mmol/l,and 40.24% at 200 mmol/l.It was up to 18.41% and 42.22% respectively after 48 h.In Alendronate-treated GCT cells,Caspase-3 activation was observed.The cell response varied with doses of Alendronate showing the levels of Caspase-3 expression with a dose dependent response.[Conclusion]In conclusion,we demonstrated that bisphosphonate alendronate could inhibit GCT cells in the present study.This response was time-dependent and dose-dependent.Alendronate inducing apoptosis in GCT cells is mediated by the activation of Caspase-3.

Objective To investigate the protective effects of ulinastatin on the lungs in patients undergoing lung resection after chemotherapy for lung cancer.Methods Thirty ASA Ⅱ or Ⅲ patients with lung cancer(Ⅲ a)aged 54-71yr weighing 55-74 kg undergoing lung resection after chemotherapy were randomly divided into 2 groups(n=15 each):Ⅰ ulinastatin group received ulinastatin 10 000 U?kg~(-1) after induction of anesthesia and Ⅱ control group received normal saline instead of ulinastatin.The patients were premeditated with intramuscular pothidine 70 mg and scopolamine 0.3 mg or atropine 0.5 mg.Anesthesia was induced with midazolam 0.05 mg?kg~(-1),fentanyl 4 ?g?kg~(-1) propofol 0.5-1.0 mg?kg~(-1) and vecuronium 0.1 mg?kg~(-1) and maintained with 1%-2% isoflurane inhalation and vecuronium infusion at 0.06-0.08 mg?kg~(-1)?h~(-1).Blood samples were taken after induction of anesthesia(T_1,baseline),at 40 and 90 rain of one-lung ventilation(T_2,T_3) for determination of serum IL-6,IL-8,IL-10 and TNF-? concentrations.Lung specimen was taken from the operated lung at 90 min of one-lung ventilation for microscopic examination with light and electron microscopo.Results Serum IL-6,IL-8,IL-10 and TNF-? concentrations were all significantly increased during one-lung ventilation as compared to the baseline values at T_1 in both groups.Serum IL-6,IL-8 and TNF-? concentrations were significantly lower while Serum IL-10 concentration was significantly higher in ulinastatin group than in control group during one-lung ventilation(P＜0.05).The histopathologic changes of lung tissue were significantly less in group utinastatin than in group control.Conclusion Ulinastatin can effectively protect the lung in patients with lung cancer after chemotherapy by reducing systemic inflammatory response.

Although the treatment has made great progress in breast cancer, there are still many problems. For example, primary or secondary on chemotherapy drug resistance and the limitation of treatment in triple-negative breast cancer. So, targeted therapy has become a new strategy to improve this situation. Previous studies showed that the occurrence of breast cancer may be related to the activation of PI3K/Akt/mTOR signaling pathways, and mTOR is an index to judge the prognosis. Parts of breast cancers can obtain clinical benefit with mTOR inhibitors, and it might be a potential treatment target in breast cancer.
