[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.

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.

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.

Objective. To investigate the mechanism of tazarotene in active psoriasis vulgaris. Methods. HB-EGF protein in active psoriatic lesions before and 10 days after the treatment of tazarotene was detected by immunohistochemistry. Results. There was nearly no expression of HB-EGF in psoriatic lesions (9.1%), but after the treatment by tazarotene, there was expression of HB-EGF not only in basal layer (95.5%), but also focal expression in suprabasal layers of epidermis (77.3%). Conclusion. Tazarotene inhibit proliferation and induce apoptosis of keratinocytes through upregulating expression of HB-EGF in psoriatic epidermis.

BACKGROUND:It can be confirmed by the clinical trial that chronic plantar fasciitis can be treated by extracorporeal shock wave.There are some different explains for the mechanism of action.OBJECTIVE:To introduce the mechanism of action and clinical application of extracorporeal shock wave in the treatment of chronic plantar fasciitis.RETRIEVAL STRATEGY:A computer-based search was conducted in PUBMED,HighWire and Springer databases for articles published before August 2007 with the key words of "chronic plantar fasciitis,extracorporeal shock wave application" in English by the first and second authors.Inclusive criteria:articles were selected firstly based on the mechanism of action and clinical application of extracorporeal shock wave for chronic plantar fasciitis.Exclusive criteria:articles out-of-date and repeated were removed.LITERATURE EVALUATION:Sixty-five relevant articles were collected,and twenty-five met the inclusive criteria.Of them,4 articles were review,and others were about the mechanism of action and clinical application of extracorporeal shock wave for chronic plantar fasciitis.DATA SYNTHESIS:①Someone believed that high energy shock wave selectively damaged unmyelinated sensory nerve fibers.Low energy shock wave could inhibit the conduction of sensory nerve ending by releasing calcitonin-gene-related peptide and producing neurogenic inflammation.It also could play a long-term analgesic effect by making the changes in regional flow of the brain,regulating pain memory and reducing local stimulatory response.②There are many reports on short-term and long-term outcomes,different energy levels,local anesthetic drug,the depth of plantar fasciitis and therapeutic place.CONCLUSION:It is effective to treat chronic plantar fasciitis by extracorporeal shock wave.Different approaches can bring us different therapeutic outcomes.

During lymphocyte development antigen receptor genes undergo V(D)J recombination to obtain antigen binding specificity and diversity. This process is not only controlled by genetic factors, such as tissue- and stage- specificity of RAG-1/2 protein, germline transcriptional activity and ACEs, but also regulated at epigenetic level. The chromatin accessibility of recombinase is associated with the chromatin configuration around the targeted gene segments. Thus, activation of V(D)J recombination requires the recruitment of remodeling complexes for changing the accessibility in the localized chromatin. Moreover, docking of remodeling complexes, which serve for creating active chromatin environment, relies on certain patterns of chromatin modification. Some recent findings regarding epigenetic regulation mechanisms in V(D)J recombination, such as CpG methylation, histone modification, nucleosome remodeling and nuclear topology were reviewed.
