Objectives:To observe the influence of PN treatment on the postoperative patients of advanced ovarian cancer. Methods:The patients were divided into two groups.Thirty cases of patients(PN group) were treated with PN after the operation for the ovarian cancer.Thirty five cases of patients(control group) were treated regularly without PN.The biochemical indicators,complications and mortality rate were compared between the two groups. Results:The biochemical indicators in PN group were better than those in control group.The incidence of complications and mortality rate in PN group were significantly lower than those in control group. Conclusions:PN can improve the general status of postoperative patients with advanced ovarian cancer and decrease the complication incidence and motality rate.

Objective To compare clinical outcome of microvascular decompression (MVD) and percutaneous balloon compression (PBC) by using a prospective cohort study in order to provide a reliable evidence for the clinical decision-making. Methods Patients with trigeminal neuralgia hospitalized at Hangzhou First People′s Hospital in 2010 were chosen as database for cohort study. The patients were divided into MVD group (30 cases) and PBC group (30 cases). The clinical efficacy was followed by independent observers for 36 months after surgery. Chi-square test for hierarchical data, t test for quantitative data, and Kaplan-Meier plot for clinical outcomes were applied in the research. The endpoint was follow-up accomplishment or severe occurrence. Results Sixty patients were included in the research till the endpoint. The general records before surgery were almost the same with the literature records. By comparing painless period, mild and severe relapse, MVD group was superior to PBC group (P < 0.05). As for the painless survival period, MVD group was 96.7% of pain free after 1 year, 93.3% after 3 years, while PBC group was 90.0% after 1 year and 83.3% after 3 years. Regarding 3 years of follow-up, the relapse seemed occurred after 1 year in both groups. Conclusions As a curative and nondestructive procedure , MVD is more effective and has longer lasting pain free period , which should be considered as the first choice of treatment for trigeminal neuralgia in healthy people.

BACKGROUND: A large number of researches have confirmed that hypertension, vascular nephrosclerosis and chronic systemic inflammatorome were the importance factors of chronic allograft dysfunction. Hyperuricemia is associated with primary hypertension and vascular nephrosclerosis, and can result in chronic systemic inflammatorome, but it was uncertain whether post-transplantation hyperuricemia and its lesion influence the long term graft function. OBJECTIVE: To investigate the prevalence of hyperuricemia in renal transplant recipients (RTRs) before and after transplantation and the influence of hyperuricemia on long term graft function. METHODS: A total of 216 renal transplant recipients [146 males with the mean age of (40.98±11.09) years and 70 females with mean age of (40.01±11.62) years]with normal renal function after transplantation were selected from PLA Center of Kidney Transplantation and Dialysis, the 181 Hospital of Chinese PLA. In order to compare the influence of different hyperuricemia status on the long term graft function, the patients were divided into 4 groups according their pre-transplant baseline and post-transplant serum uric acid (SUA) levels, SUA normal group, pre-transplant high SUA group, post-transplant high SUA group and both pre-transplant and post-transplant high SUA group. The patients were also divided into 3 groups according to their post-transplantation SUA level to study the influence of SUA on the long term graft function, normal SUA group, hyperuricemia (SUA < 500 μmol/L) group and hyperuricemia (SUA > 500 μmol/L) group. Effects of hyperuricemia and SUA levels pre-and post-transplantation on long term graft function were observed. RESULTS AND CONCLUSION: Hyperuricemia existed in 34.2% male RTRs and 37.7% females before transplantation, while it existed in 36.2% male RTRs and 42.4% females at the first month post-transplantation when they had normal Scr levels. The incidence rate of post-transplant hyperuricemia in female RTRs was significantly higher than male RTRs (P < 0.05). The average post-transplantation SUA levels in both male and female RTRs were significantly higher than those before transplantation (P < 0.01). At follow-up end, the pre-transplantation SUA levels did not significantly influence on the long term graft function (P > 0.05), meanwhile the RTRs with continuous post-transplant hyperuricimia had poorer long term graft function than those with normal post-transplantation SUA levels. It is indicated that hyperuricemia is more common in post-transplantation recipients, especially in female RTRs, when compared to pre-transplantation, and post-transplantation hyperuricemia often existed in renal transplant recipients with normal graft function. Furthermore it is suggested that post-transplantation hyperuricimia, but not pre-transpiantation hyperuricemia, could also act as a factor inducing chronic renal allograft dysfunction.

Objective: To investigate the influence of TGF-β and IFN-γ on the proliferation, migration and invasion of melanoma cells. Methods: Melanoma cells were cultured in vitro. When tumor cells were confluent about 80% degree, cytokines were added into cell culture media. The concentration of TGF-β and IFN-β was 5ng/mL and 10ng/mL, respectively. Melanoma cells were divided into free-cytokine group, TGF-β group,IFN-γ group, TGF-β and IFN-γ group. Tumor cells in each group were then incubated for 8h, 16h, 24h, 32h,40h and 48h, respectively. After incubation, fixing and staining with SRB, the optical densities and percentage viability were then determined by absorption at 540 nm (A 540). The scarification of tumor cells in each group on the surface was created by a 2001μL pipette tube. The motility of tumor cells in each group was assessed by measuring the distance between scarifications. The speed of the scuffing closure was monitored after 12h.The invasive ability of melanoma cells was observed by transwell cultivation. The tumor cells that invaded through the Matrigel and adhered to the bottom of the outside membrane were determined by absorption at 595 nm (A595). Gelatin zymography assay was used to examine the levels of matrix metalloproteinases-2 (MMP-2) and matrix metalloproteinases-9 (MMP-9) activity when the tumor cells were treated with cytokines after 24h. MMP-2 and MMP-9 activity was demonstrated by gradation in the sodium dodecyl sulfate polyacryl-amide gel electrophoresis (SDS-PAGE) gelatin. MMP-2 and MMP-9 activity was determined by Image analy-sis Software. Results: TGF-β promoted the proliferation, migration and invasion of melanoma cells (P<0.05).However, IFN-γ inhibited the proliferation, migration and invasion of melanoma cells (P<0.05). The effect weakened or disappeared when both of them were used (P>0.05). Conclusion: In vitro, TGF-β may affect the inhibitory effect of IFN-γ on the proliferation, migration and invasion of melanoma cells. This study provided a better understanding of the relationship between tumor and inflammatory factors and established a good ba-sis for future research.

Objective To investigate the risk factors of insulin resistance(IR)and its relationship with metabolic syndrome in patients after lenal transplantation.Methods 133 renal transplant redpients who had not undergone acute rejection,calcinurine intoxication and severe infection,and had normal renal function and no proteinuria at the 6th month post-transplantation,were involved in the study.They had a history of chronic glomerulonephritis as the primary disease of ESRF but rio diabetes mellitus.108 recipients(CsA group)were treated with CsA,mycophenolate mofetil(MMF)and prednisone after transplantation,19 recipients(Tac group)with tacrolimns(Tac),MMF and prednimne,and 6 recipients with Simlimus,respectively.One year later,blood and urine biochemical tests and physical examinations were performed on the recipients,and HOMA calculated.200 cormnunity residents were randomly selected as controls.Results The incidence of MS in the recipients was 33.1%,significantly higher than controls(15.0%).There was no significant difference in the incidence of obesity and overweight between recipients(29.3%)and controls(37.5%).In recipients with obesity or overweight,the insulin-resistance level and urine albumin level,and the incidence of MS weree significantly higher than those without obesity or overweight.The insulin-resistance level in Tac-treated recipients was markedly higher than CsA-treated recipients,and there was a positive correlation between the blood concentration of Tac and insulin-resistance levd.Microalbuminufia-positive recipients had higher insulin-resistance levels.Metabolic syndrome-complicating recipients had higher insulin-resistance levels than those without metabolic synawme,and higher insulinresistance levels existed in recipients with hypertriglyceridemia or hyperchcllesterolemia,hypertension.Conclusion Obesity or overweight,Tac(especially when blood concentration was higher)were risk factors resulting in imulin-resistanee in kidney transplant recipients.It is suggested that insulin-resistance might be involved in the pathogenesis of metabolic syndrome including hypertrglyceridmaia,hypercbolestemlemia and hypertenion.

Objective To explore the role of heme oxygenase-1 (HO-1) gene expression on murine experimental abdominal aortic aneurysm (AAA).Methods Wistar rats were divided into hemin (experimental group) and saline (control group) group randomly, and experimental AAA model was established by elastase perfusion. The specimen was obtained at postoperative day 7, and the dilatation rate was calculated. In situ hybridization was applied to detect the expression of HO-1 mRNA in aortic wall, while immunohistochemical staining was used to detect the protein expression of ICAM-1 and HO-1. Results In experimental group, the aorta dilation was inhibited and aneurysm was not observed. In experimental group, HO-1 mRNA and protein expression was strengthened (P

0.05).But its incidence was higher in females than in males after transplantation(P

Objective To analyze the MRI features of hydrosalpinx and to investigate its clinical value.Methods MRI and ultrasound manifestations in 40 patients with hydrosalpinx in 53 fallopian tubes confirmed by operative and pathological findings were analyzed retrospectively,and these findings were also compared with the results of aparoscopy and pathology.Results Among 53 fallopian tubes with hydrosalpinx,bilateral tubes in 13 patients and 27 unilateral tubes in other patients were found.The tubes were botuliform in 32, retort-shaped in 1 6,pouch-shaped in 5.Incomplete separation of the lumen were found in 1 9.In 9 patients with acute salpingitis,1 5 tubes were found with empyema and expansion.In other 31 patients with chronic salpingitis,38 tubes were with hydrops and expansion,14 of whom were with hematocele.The sensibilities of MRI and ultrasound diagnosis for hydrosalpinx were 94.3%(50/53)and 88.7%(47/53)with no statistical differences(P >0.05),however the specificitis were 90.6%(48/53)and 77.6%(41/53)with obvious statistical differences(P <0.05).Conclusion The locating and qualitative diagnosis of MRI for hydrosalpinx is superior to ultrasound.MRI can discriminate the quality of cyst fluid and thus can definitely diagnose the hydrosalpinx caused by acute or chronic salpingitis.

Objective To explore vascular smooth muscle cell(SMC) proliferation and cell apoptosis during the development of abdominal aortic aneurysm(AAA). Methods The animal model of AAA was established in Wistar rats and the specimens were harvested at the 3rd day,and 1、2、3 and 4 week after the model initiation. In situ end-labeling of DNA fragments (TUNEL) was used to detect SMC apoptosis and immunohistochemical staining was applied to investigate the expression of SMC apoptosis markers(bcl-2,bax),proliferating cell nuclear antigen (PCNA) and ?-actin. Results TUNEL-positive and PCNA-positive SMC reached the maximum at 2～3 week and 1 week respectively;The count of TUNEL-positive SMC was less than PCNA-positive SMC during the period of day 3 to 1 week and that was vice versa from 2nd to 4th week with SMC amount significantly decreased;Bcl-2 and bax protein was strongly expressed at 1 week and 3 week after operation(all P

Objective: To investigate the incidence of coutrast media iodixanol-induced delayed adverse reaction with the risk factors in general clinical practice.
Methods: A total of 20,185 patients with contrast iodixanol were recruited from 95 medical centers in China. The risk factors for adverse drug reaction as hypertension, asthma, previous contrast reaction were assessed;the administrative processes as route, injection manner, lfow rate of injection, prior heating of iodixanol were monitored and the demographic information was documented. The immediate adverse reaction within 1 hour of media administration and the delayed adverse reaction from 1 hour to 7 days after administration were recorded. The risk factors for iodixanol-induced delayed adverse reaction were studied by singlevariate and multivariate logistic regression analysis.
Results: The overall iodixanol-induced adverse reaction rate was 1.52%, of which the immediate reaction was 0.58%and delayed reaction was 0.97%. The major delayed reaction was mild and it mostly happened in skin (0.68%) including rash, pruritus and urticaria. Multivariate logistic regression analysis revealed that male gender (OR=0.71, P=0.036), age (OR=0.82, P=0.001), route of administration (OR=0.21, P<0.001), prior heating of iodixanol (OR=1.44, P=0.036), lfow rate of injection (OR=1.28, P=0.001) and previous contrast reaction (OR=16.04, P<0.001) were the independent risk factors for delayed adverse reactions.
