Objective:To analyze the curative effect of suppression expression of URG4 on cervical cancer mice and the possible mechanisms.Methods:The expression of URG4 were analyzed in cervical cancer tissues and para-carcinoma tissues.16 male BALB/c nude mice were divided into Group A ( inoculated with URG4-siRNA SiHa cells) and Group B ( inoculated with SiHa cells) . After 4 weeks,mice were executed and analyzed.Results:The expression of URG4 were higher in human cervical cancer tissues than that in para-carcinoma tissues ( P<0.05).After experiment,Group A had a lower tumor weight,but a higher body weight than these of Group B,the difference was statistically significant (P<0.05).Group A mice had a lower levels of URG4 in tumor than that of Group B mice (P<0.05).Group A mice had a lower levels of Ki67 in tumor than that of Group B mice,the difference was statistically significant (P<0.05).Group A mice had lower levels of CyclinD1,β-catenin and C-myc in tumor than these of Group B mice (P<0.05). Conclusion:The expression of URG4 in cervical cancer tissue is up-regulation.Suppression expression of URG4 can suppress tumor growth in vivo,which may though suppress the Wnt/β-catenin signaling pathway.

Inflammatory bowel disease (IBD) is a group of intestinal chronic non-specific inflammatory disease with unknown etiology, and includes ulcerative colitis (UC) and Crohn''s disease (CD).Studies have indicated that environmental factor, genetic factor, disorder of immunity are associated with the pathogenesis of IBD.More and more basic and clinical studies focus on treatment with helminths in IBD.The accumulated evidences have shown that helminths infection has beneficial effects on the alleviation of IBD and is relatively safe.This article reviewed the advances in study on helminths in the treatment of IBD.

Objective To study the regional homogeneity (ReHo) of default-mode network (DMN) in patients with minimal hepatic encephalopathy (MHE) with resting state fMRI.Methods Eighteen MHE patients and eighteen healthy controls (HC) underwent standard resting state fMRI scan.The resting state fMRI data were analyzed with the ReHo method to observe the changes of DMN in the patients in contrast to the controls.Results Compared to healthy controls,MHE patients showed lower ReHo in bilateral MPFC/anterior cingulate cortex(V=13.257 cm3;MNI coordinates=3,24,66;t=-3.493 7),bilateral precuneus/posterior cingulate cortex(V=4.752 cm3;MNI coordinates=9,-54,45;t=-2.634 1),while higher ReHe in right medial prefrontal cortex(V=5.049 cm3;MNI coordinates=21,63,6;t=4.017 5).Conclusion In MHE patients,there is abnormal neuron activation in the widespread DMN regions under resting state, which indicated abnormal spontaneous activity consistency within DMN and endogenous brain function injury in MHE patients.ReHo can be used to observe DMN changes in MHE patients.

Objective To explore the method of the major hospital indexes examination using clinical pathway as an opportunity.Methods Based on the material of our hospital from 2008 to 2010,reference the data of the same level hospital in Xinjiang Uygur Autonomous Region,we set the benchmark and formulated the examination standard of three examination indexes:average length of stay (ALOS),average hospitalization expense and drug proportion.Meanwhile,we took the subentry incentives to give the corresponding reward to clinical departments according to the decreases rate compared with the benchmark monthly.Results ALOS,average hospitalization expense and drug proportion of department and the whole hospital were obviously decreased compared with the same period last year,and the differences were statistically significant (Medical system:t =27.479,14.462,11.362,all P ＜ 0.01 ; Surgical system:t =18.944,16.029,12.071,all P ＜ 0.01).Conclusion After using the examination methods and combining clinical pathway,the effects are obvious,which can effectively shorten ALOS,reduce average hospitalization expense and drug proportion,so as to relieve the patients' economic burden.

Objective To investigate the expression and early diagnosis value of CD64 index levels in peripheral blood cells in patients with postoperative traumatic sepsis.Methods A number of 420 trauma patients were enrolled in the study,and they were divided into the postoperative traumatic sepsis group(130 cases)and postoperative general trauma group(290 cases)according to the clinical manifestations. The CD64 levels in peripheral blood were measured by flow cytometry,and the levels of C-reactive protein(CRP)and white blood cell count (WBC)were detected.The diagnostic value of these indexes on postoperative traumatic sepsis were evaluated.Results The CD64 index, CRP and WBC levels in postoperative traumatic sepsis group were significantly higher than postoperative general trauma group(P <0.05). After appropriate treatment,the CD64 index,CRP and WBC levels decreased significantly compared with the preoperative levels(P <0.05). The correlation analysis showed that the CD64 index in peripheral blood and CRP level were positively correlated(r =0.79,P <0.01).How-ever,the CD64 index in peripheral blood and WBC level were of no significant correlation(r =0.028,P >0.05).The ROC curve analysis showed that when CD64 index(7.21)considered as the boundary for early diagnosis of postoperative traumatic sepsis,the sensitivity and spe-cificity of diagnosis for postoperative traumatic sepsis were 85.1% and 87.8%,the area under the ROC curve(AUC)was 0.865(95%CI 0.784 ~0.929),which was significantly better than CRP index.Conclusion The expression of CD64 is higher in patients with postoperative traumatic sepsis,which can be used as an effective indicator for early diagnosis of postoperative traumatic sepsis,and it has an important clin-ical application value.

Objective To establish an animal model of sacral nerve root avulsion in rats and e-valuate its efficiency. Methods A total of 20 adult SD rats (either sex) were chosen at random to es-tablish the sacral nerve root avulsion model by avulsing the fight L4-6 nerve roots out of intervertebral fo-ramina without laminectomy. The left side was set as control group. The models were evaluated in aspects of survival rate, Basso-Beattie-Bresnahan (BBB) scores, somatosensory evoked potential (SEP), horse radish peroxidase (HRP) tracing, bilateral weight and cross section area (CSA) of muscle biceps femo-ris, fiber of triceps surae and anterior tibial muscle. Results Of all, 19 rats were survived but one died, with survival rate of 95.0%. The BBB score was (10.78+3.15) points in experimental group and 21 points in control group. The success rate of establishing animal model was 89.5% ,for there detected no SEP in bilateral cerebral cortex of the wounded extremity of 17 rats. HRP showed positive reaction in the spinal segment of L4-6 in two rats but negative in 17, with success rate of 89.5%. There was statistical difference in aspects of weight and muscle fiber CSA of double biceps femoris, triceps surae and anterior fibial muscle between experimental group and control group. Electron microscope found denervation chan-ges including muscle fiber atrophy, nucleus shifting to (center and muscle satellite cell. Conclusion A-vulsion of L4-6 sacral nerve root out of vertebral canal is a feasible and ideal method to establish the avui-sion model of sacral nerve root injury in rats.

Objective To investigate the prevalence and clinical characteristics of Sj?gren′s syndrome-interstitial lung disease (SS-ILD). Methods 136 patients with SS were studied. Anti-SSA and Anti-SSB antibodies were measured by Western blot. The inpatients had chest X ray, chest HRCT and pulmonary function examined. Results ①pSS-ILD patients with postive anti-SSA antibody were proned to have interstitial lung disease and the ILD were more severe. ②HRCT showed that sSS-ILD were more severe than that of pSS-ILD. ③Lung capacity of pSS-ILD decreased more frequently than sSS-ILD. sSS-ILD mainly had venti-latory function abnormalities. The lung function impairment of both were dominated by small airways dysfunction and decrease of TLCO. Conclusion SS patients should be examined by HRCT and lung function tests should be performed in the course of the disease to find out and treat ILD.

In June 2018, the hyaluronic acid chin augmentation was performed on a 24-year-old female patient in Xi′an Goose Pagoda Beauty Hospital. After surgery, the patient′s left half of the tongue became pale and turned to dark purple thereafter. The patient had pain and discomfort in tongue, accompanying with pharyngeal swallowing difficulty. It was speculated that the refluxed hyaluronic acid from submental artery to the left lingual artery. Hyaluronidase was immediately injected. The thrombolytic, vasodilatory, and prophylactic antibiotic treatment were assisted. After 8 days, the pain of tongue was significantly improved, and the color returned to normal.

With the continuous development of bone tissue engineering, a variety of emerging bone graft materials provided various methods for repairing bone defects. Early and rapid accomplishment of revascularization of materials interior after implantation of bone transplantation materials is a difficulty faced to bone tissue engineering. Blood vessels ingrowth provides the requisite netritional support for the regeneration reconstruction of bone tissue, for this reason, vascularization plays a significant role in bone tissue engineering. However,there is not a golden standard strategy of vascularization at present. Scaffold materials, cells and growth factors still are three indispensable elements in tissue engineering, and are cardinal points of the promoting vascularization strategies. Multiple growth factors or multiple cells combined with scaffolds, which are hot spots, have obtained excellent vascularization. This review focused on the comprehensive strategies for promoting the successful vascularization of tissue engineered scaffolds.
