The activities of interleukin 6 (IL 6) and tumor necrosis factor alpha (TNF?) produced by peripheral blood mononuclear cells (PBMCs) in vitro and their relevant levels in sera were measured in 49 patients with psoriasis vulgaris (PV) and in 20 normal controls using bioassay. The relationship between them was also analysed. The results showed that in PV patients the activites of IL 6 and TNF? produced by PBMCs and their serum levels were higher than those in healthy controls. There was a positive linear correlation between the activites in vitro and relevant levels in sera, and a positive linear correlation between serum levels of IL 6 and TNF?. These results indicate that there is dysfunction of cellular immune of PBMCs in PV patients. The increase of serum levels of IL 6 and TNF? may be related to the increased activity of PBMCs, and there may be a synergic action between IL 6 and TNF? in the pathogenesis of psoriasis.

OBJECTIVE:To compare and analyze blood concentration changes of fluorouracil administered to guinea pigs by different paths.METHODS:The peripheral vein and portal vein blood samples of guinea pigs were taken at different time after administered with fluorouracil in3different ways:group A(by arterial infusion),group B(by intravenous infusion)and group C(by celiac infusion).The blood concentration changes were determined and analyzed by HPLC.RESULTS:The portal vein and peripheral vein blood concentrations in group A and B reached peak value5min after administration with flu?orouracil while group C reached peak at10min;the portal vein blood concentrations in group A reached the highest in the first20min while group C showed the highest value in the last30min.CONCLUSION:Arterial infusion combining celiac infusion path was recommended for local chemotherapy;arterial infusion combining intravenous infusion or intravenous infusion com?bining celiac infusion was recommended for the local therapy while giving consideration to systemic chemotherapy.

Objective To evaluate the analgesic effects of continuous infusion of morphine into epidural space(CIEA) on postoperative pain relief after prostatectomy. Methods 40 cases of benign prostate hypertrophy were selected and randomly divided into two groups,experimental group(CIEA),0 2mg/h of morphin was injected into epidural space,control group(MI),50mg of pethidine was injected whenever patient feel pain.VAS(Vision simulate score),frequency and duration of bladder spasm,discontinuance time of bladder irrigation,HR BP and RR,were observed. Results The experimental group was superior to the control group with characteristics of stable analgesic effect,short duration and low frequency of bladder spasm(P

Objective To compare the diagnostic efficiency in showing the responsible blood vessels for neurovascular compression in patients with trigeminal neuralgia by 3D‐FIESTA‐C and 3D‐TOF‐MRA sequences .Methods The imaging data of 60 patients with primary trigeminal neuralgia were analyzed retrospectively .After MRI examination ,all of the patients underwent micro‐vascular de‐compression (MVD) .3D‐TOF‐MRA and 3D‐FIESTA‐C sequences were performed to evaluate the three‐dimensional relationship be‐tween trigeminal nerve and blood vessels through the original and reconstructed image .The intraoperative endoscopic findings were set as the gold standard comparing to the manifestations of 3D‐TOF‐MRA and 3D‐FIESTA‐C .Results The sensitivities of 3D‐TOF‐MRA and 3D‐FIESTA‐C for the diagnosis of the existence of responsible vessels were 85 .7% ,89 .3% ,the specificities were 75 .0% , 100% ,and the accuracies were 85 .0% ,90 .0% ,respectively (P=1 .000) .Furthermore ,the sensitivities of 3D‐TOF‐MRA and 3D‐FIESTA‐C for the diagnosis of the existence of responsible arteries were 94 .1% ,88 .2% (P=0 .244) ,while the sensitivities of the responsible veins were 0 .00% and 88 .2% (P=0 .009) .Conclusion Both the 3D‐FIESTA‐C and 3D‐TOF‐MRA sequences can accurately deter‐mine the existence of responsible vessels in trigeminal neuralgia before surgery .3D‐FIESTA‐C sequence is superior to 3D‐TOF‐MRA for presenting the responsible veins ,which can be used as a supplemental diagnostic tool before operation .

Objective To analyze the urodynamic abnormalities of incontinent stroke patients,and evaluate the effects of acupuncture,moxibustion in combination with physical therapy.Methods One hundred and six in- continent stroke patients were divided into a control group and a treatment group.The control group was treated with conventional methods,and the treatment group with acupuncture,moxibustion and physical therapy modalities such as ultrasound and EMG biofeedback.The Urodynamic examination was performed before and after treatment.Re- sults It was found that the uradynamic abnormalities in the incontinent stroke patients include detrusor hyperreflexia and uninhibited sphincter relaxation.Combined use of acupuncture,moxibustion and physical therapy can significant- ly improve the patients' symptoms.Conclusion Common urodynamic abnormalities.are detrusor hyperreflexia and uninhibited external sphincter relaxation in incontinent stroke patients.Combined use of acupuncture,moxibustion and physical therapy is effective for treating this condition.

Background and purpose:miR-17-92 gene cluster overexpression has been observed in various cancers, such as lung cancer, liver cancer, gastric cancer and prostate cancer. In this study, we established the stable cell line overexpressingmiR-17-92 to explore the inlfuence ofmiR-17-92 on the migration, invasion abilities and cisplatin resistance of the prostate cancer DU145 cells.Methods:miR-17-92 overexpression vectors were constructed. DU145 cells were infected with the viral supernatants produced by Phoenix A packaging system. Real-time lfuorescent quanti-tative polymerase chain reaction (RTFQ-PCR) was conducted to detect the expression level of miR-17-92 in the cells. The migration and invasion abilities were measured by a real-time xCELLigence system. The scratch healing assay was carried out to investigate the migration abilities. The expression of integrin β1 was detected by Western blot, and the activities of matrix metalloprotein-2 (MMP-2) and matrix metalloprotein-9 (MMP-9) were measured by gelatin zymography experiment. The cell growth of the two cell lines after the treatment of cisplatin was detected by a real-time xCELLigence system. The mRNA expression ofERCC1 was measured by RTFQ-PCR. Western blot was conducted to investigate the protein expressions of ERCC1, ERK1/2 and pERK1/2.Results:DU145-miR-17-92 cells migrated faster than DU145-control cells during the 24 h continuous monitoring (P<0.01). The scratch healing assay indicated that DU145-miR-17-92 cells migrated from the edge towards the scratch center faster than DU145-control cells. DU145-miR-17-92 cells invaded through matrigel markedly faster than DU145-control cells (P<0.01). The protein expression level of integrin β1 and the MMP-9 activities in DU145-miR-17-92 cells were increased than those in DU145-control cells. After the treatment of cisplatin, DU145-miR-17-92 cells grew faster than DU145-control cells, presenting cisplatin resistance (P<0.01). The phosphorylation of ERK1/2 in DU145-miR-17-92 cells was constantly at a high level regard-less of the treatment of cisplatin. Compared with DU145-control cells, the expression of drug resistance-related gene ERCC1 was dramatically increased in DU145-miR-17-92 cells after the treatment of cisplatin.Conclusion:miR-17-92 overexpression increases the migration and invasion abilities of the prostate cancer DU145 cells, which is associated with the upregulated expression of integrin β1 and the increased activity of MMP-9. Besides,miR-17-92 overexpression enhances the cisplatin resistance of DU145, which is correlated with the increased phosphorylation level of ERK and the upregulated expression of ERCC1 at both the mRNA and protein levels.
