[Objective] To discuss the clinical effect of nasal intestinal obstruction(IO) conduct catheterization on IO after ovarian cancer operation. [Method] Choose 25 cases of IO after ovarian cancer operation, randomly divide them into treatment group 10 cases and control one 15 cases. The control group take general nasogastric tube imbedding, the treatment group take nasal IO conduct catheterization;observe their post-operational complications and clinical cure effect. [Result] On complications in control group, 8 cases had electrolyte disturbance, with complication rate 53.33%, the part of clinical symptoms was re-lieved, the IO signs did not disappear or were reduced partly with X-ray;5 cases were cured clinical y, 3 had marked effect, 3 were effective, 4 had no effect, the total effective rate was 73.33%;for the treatment group, al cases were successful y imbedded and made decompression and drainage, there ’s no severe side effects after imbedding tube, the IO symptoms were effectively relieved;1 case was transferred to operation;6 cases were cured clinical y, 3 had marked effect, 1 was effective, 0 had no effect, the total effective rate was 100%;after cathetering, there ’s no severe complications, among which, 2 cases had electrolyte dis-turbance, the post-operation complication rate was 20%. The comparison of complication rate and clinical effective rate of both groups had difference of sta-tistical meaning. [Conclusion] Nasal IO conduct imbedding treating IO after ovarian cancer operation had more effect on relieving IO symptoms and reduc-ing complications than nasogastric tube.

Objective To investigate the expression patterns of osteopontin (OPN) , vascular endothelial growth factor-A (VEGF-A) , and hypoxia-inducible factor-1α (HIF-1α) in primary hepatocellular carcinoma (HCC) and determine the clinical significance of this differential expression profile.Methods Immunohistochemical staining of OPN, VEGF-A, and HIF-1α was carried out on primary HCC tissues from 90 patients, HCC-adjacent cirrhosis tissues from 20 of those patients, and normal liver tissues from 15 healthy controls.Correlations between expression levels and HCC clinicopathological characteristics were assessed by Spearman's correlation coefficient.Results The majority of HCC tissues showed positive immunostaining for OPN (69/90, 76.67%) , VEGF-A (64/90, 71.11%) , and HIF-1α (66/90, 73.33%) .OPN-and VEGF-A-positivity were significantly higher than the results from the cirrhosis tissues and normal tissues.HIF-1α-positivity was similar between the HCC and cirrhosis tissues, but both were significantly different from the normal tissues.The differential expressions of OPN, VEGF-A, and HIF-1α were significantly correlated with tumor thrombus, capsular integrity, tumor differentiation and stage, and metastasis (P<0.05) .Conclusion HCC tissues overexpress OPN, VEGF-A, and HIF-1α and this differential profile may be related to HCC progression.Future investigations of this triad of factors may provide novel insights into the biological characteristics of HCC and reveal important targets of molecular therapy.

Analysising of the students' role will contribute to improve the quality of clinical teaching.The core of the students' role is “student”,they are the principal part of the learning activities.At the same time,students have on the shoulders the practice role of clinical nurse.The remarkable thing is that the students have kinds of needs of different levels,they should be regarded as the holistic person who have the individual otherness and commonness and the inimitable value.The characteristic of students can influence their behaviors in clinical activities.

Background Studies showed that traumatic optic neuropathy (TON) can activate and induce immuno-inflammatory response,while T helper cell 17 (Th17), a CD4+ T lymphocyte, is associated with immunoinflammatory response.However,the effects of Th17 on the development of TON are unclear.Objective This study was to observe the changes of Th17 lymphocytes in spleen and the expression of interleukin-17 (IL-7) in retina in TON rats.Methods Seventy male 4-week-old SD rats were randomly divided into normal control group, sham operation group and TON 1-, 3-,7-, 14-and 28-day group according to random number table.The optical nerves of the right eyes were exposed and impacted at a 25° angle by using fluid percussion injury (FPI) device with the average force (699.1±60.8) kPa to create the TON models in the TON groups,and only optical nerves were exposed in the sham operation group.Flash visual evoked potential (F-VEP) was recorded and the amplitude and latency were measured to evaluate the function of optical nerves of the rats.The rat splenocyte suspension in various groups was prepared for the detection of Th17 cells by flow cytometry, and the expression of IL-17 protein was detected by immunochemistry.Results No significant differences were found in the amplitudes and latencies of P2 wave, proportion of Th17 cells and the IL-17 positive cell numbers in retina between the normal control group and sham operation group (P =0.829,0.830,0.856,0.496).The amplitudes of P2 wave were significantly lower, and the latencies of P2 wave were significantly longer in the TON groups than those in the sham operation group (all at P＜ 0.05).The proportions of Th17 positive CD4+ T lymphocytes were (0.94±0.13)％,(1.80±0.18)％,(1.98± 0.20)％ ,(2.34±0.20)％ ,(2.11±0.13)％ ,(1.92±0.18)％ in the sham operation group,TON 1-day group,TON 3-day group,TON 7-day group,TON 14-day group and TON 28-day group, respectively, showing significant differences between the sham operation group and various TON groups (all at P＜0.05).In addition, the IL-17 positive cell numbers in retina were 796.326 ± 100.028, 1 673.416 ± 188.021,1 892.431 ± 151.026,2 420.454 ± 256.024,1 996.429±177.022 and 1 629.410±127.023 in the sham operation group,TON 1-day group,TON 3-day group,TON 7-day group,TON 14-day group and TON 28-day group, respectively, showing significant differences between the sham operation group and various TON groups (all at P＜0.05).Conclusions In rats of TON, the proportion of Th17 cell in splenocytes and the expressions of IL-17 in retina are increased,suggesting that Th17 and IL-17 participate in the progression of TON.

Objective To observe the effect of acupuncture on post-stroke belching. Method Ninety-six patients with post-stroke belching were randomized into a control group and a treatment group by random number table, 48 cases in each group. The control group was intervened by conventional Western medication, while the treatment group was by acupuncture in addition to the medication given to the control group. The blood Cl﹣ and Ca2﹢ contents, as well as the symptoms score and occurrence of adverse reactions were compared before and after treatment. Result After intervention, the blood Cl﹣ and Ca2﹢ contents increased and the symptoms score decreased to different extent in both groups; except for the blood Ca2﹢ content, there were significant differences in comparing all the parameters between the two groups after intervention (P<0.05); there was a significant difference in comparing the occurrence of adverse reactions between the two groups (P<0.05), and there were less adverse reactions in the treatment group. Conclusion Acupuncture can effectively control the post-stroke belching and reduce the happening of adverse reactions.

Objective To establish a liquid chromatographic-mass spectrometric method ( LC-MS/MS method ) for determination of dextrorphan in human liver microsome. Methods LC-MS/MS was adopted with carbamazepine serving as an internal standard.The separation was performed on Agilent ZORBAX XDB-C18 column (2.1 mm×50 mm, 3.5μm), with mobile phase consisting of 0. 05% formic acid methanol-0. 05% formic acid in gradient elution. Dextrorphan and carbamazepine were detected on multiple reaction monitoring(MRM)mode by transitions from precursor to production(m/z 258.1→199.1, 237.1→194.1). Results The linear range of dextrorphan concentration was 19.22-768 960 ng.L-1(r=0.999 8), and the lowest quantification limit was 19.22 ng.L-1.The relative recoveries were 94.02%-98.74%, and the RSDs of intra-day and inter-day were within 10%.IC50 of psoralen on CYP2D6 was 0.6μmol.L-1. Conclusion The LC-MS/MS method is proved to be rapid, sensitive and reproducible, psoralen is a strong inhibitor of CYP2D6.

Objective To investigate the expression of uPAR and VEGF-C in hepatocellular carcinoma (HCC) and its effect on the biological behavior of HCC. Methods The expression of uPAR and VEGF-C in liver tissue specimen of 33 patients with HCC was detected by immunohistochemical staining. Results The positive expression of uPAR and VEGF-C in HCC tissues was located in cytoplasma of cancer cells. The positive rates of uPAR and VEGF-C were 69.7 %(23/33) and 78.8 %(26/33) respectively in 33 cases of HCC. The expression rates of uPAR and VEGF-C were significantly higher in HCC with metastasis than in HCC without metastasis(P<0.05). But there were not significant correlation between the expression of uPAR or VEGF-C and tumor size, tumor grade, AFP level, hepatic cirrhosis. There was a close correlation between uPAR and VEGF-C in HCC(r=0.676, P<0.01). Conclusion The expression of uPAR and VEGF-C is correlated with metastasis, uPAR and VEGF-C may be signs of aggressive phenotype for evaluating treatment and prognosis of HCC. Examination of these two proteins may be helpful to .judge biological behavior of HCC.

Thirty two rabbits were divided into 4 groups: (1) Normal diet control group, ( 2 ) Hyperlipid diet control group, ( 3 ) Hyperlipid diet group injected with 30 mg/kg GSL, ( 4 ) Hyperlipid diet group injected with 60 mg/kg GSL, The whole expeiment took about 42 days. On 24d all hyperlipid diet were removed, and only normal diet given. At the end of this experiment all rabbits were killed by bleeding and the results showed that GSL could decrease the serum lipids GSL could increase the HDL - C in the rabbits injected with 60 mg/kg GSL. GSL could protect the walls of aortas from the damage of hyperlipid serum. The contents of lipid and MDA in the Walls of aortas were decreased. GSL had the effects of protection on the heart and liver by decreasing of Total Cholesterol and MDA. So we conclude that GSL has the effects of lipid regulation and lipid antipeoxidation on the chronic hy-perjipidemic rabits.
