Cervical cancer is women's common malignant tumor.With the extensive application of screening and early surgery,cervical cancer incidence declines year by year,but no decrease mortality trend.The patient died of cancer metastasis and recurrence.E-cadherin is the central link of intercellular adhesion,and junction complex has been confirmed by a large number of literature and closely associates cervical cancer development.This review summarizes the relevant research between E-cadherin and the occurrence and development of cervical cancers.

Objective To investigate in evaluation of various capacity requirement of probationer nurs-ing students by nurses in operation room in order to improve clinical teaching work. Methods A self-de-signed questionnaire was applied, 191 qualified teaching nurses from nine grade three A general hospitals in Beijing were invited to fdl the questionaires. The results underwent subsequent analysis. Results The teach-ers had high expectations for various capacity of the probationer nursing students. Conclusions Clinical teachers should establish feasible teaching scheme according to the existing teaching syllabus in order to in-crease teaching quality, make students gain new insights through reviewing old materials, so that they can mas-ter various technique in operation room in short time.

Objective To prepare the supersaturation self-emulsifying drug delivery system(S-SEDDS) containing silymarin and to evaluate its basic properties.Methods With the time of self-emulsifying,the consequence of color visual examination and particle size as parameters,the optimum formulations of silymarin SSEDDS were screened by solubility test,compatibility tests and pseudo ternary phase diagrams.The silymarin concentration was determined by HPLC.The in vitro dissolution characteristics of silymarin S-SEDDS were investigated with silymarin SEDDS as control.Results The optimum silymarin S-SEDDS was composed of medium chain triglycerides(MCT) 40%,Cremophor RH40(ethoxylated hydrogenatedcastor oil) 48%,Labrasol 12%.The time of self-emulsifying was less than 3 min,the average particle diameter was 49.6 nm,the adding amount of hydroxypropyl methylcellulose(HPMC) was 50 mg/g,and the average content of silymarin was 39.3 mg/g.The in vitro dissolution test of silymarin S-SEDDS showed that the presence of a small amount of cellulosic polymer effectively sustained a metastable supersaturated state by retarding precipitation kinetics.Conclusion The designed formulation of silymarin S-SEDDS is reasonable and provides a strong foundation for further development of new preparations.

Objective To investigate the radioprotective function and its mechanism of Sulforaphane (SF) in mice acute radiation-induced lung injury.Methods Totally 40 female C57BL/6J mice were equally divided into 5 groups randomly.Group A,treated by SF 3 mg/kg plus radiation;group B,treated by SF 5 mg/kg plus radiation;group C,treated by SF 10 mg/kg plus radiation;radiation group with a single dose of 12 Gy in 6 MV X-ray by a linear accelerator,and control group with sham radiation.The mice in drug group were administered intraperitoneally with different concentration of SF every other day from 7 d before irradiation to 7 d after irradiation,while the same volume of DMSO plus physiological saline solvent was given in the control and radiation groups.After being sacrificed at 14 d of SF administration,the pathomorphological changes of mice were observed in trauma lung tissue,the positioning and expression of NLRP3 was observed by immunohistochemical staining,the levels of IL-6,TNF-α and TGF-β1 in bronchoalveolar lavage fluid (BALF) were measured by ELISA,the expressions of NLRP3 and IL-1β mRNA in lung tissue were assayed by qRT-PCR,the expressions of NF-κB p65,NLRP3 and IL-1β proteins in lung tissue were assayed by Western blot,the activity of NF-κB was detected by EMSA.Results In comparison with radiation group,there was an obvious amelioration in pathological injury of lung tissue in the treatment groups:the expression of NLRP3 in lung tissue decreased;the concentration of NLRP3 in the drug intervention group (SF 10 mg / kg) markedly decreased (F =42.750,P ＜ 0.05).the IL-6,TNF-a and TGF-β1 levels in BALF decreased (tIL-6 =-62.65-21.00;tTNF-α =-32.18-16.57;tTGF-β1 =-58.22-46.11,P ＜ 0.05);the expressions of NLRP3 and IL-1β mRNA markedly decreased (tNLRP3 =-6.56-5.68;tIL-1β =-29.75--21.20,P ＜ 0.05),and the expressions of NF-κB p65,NLRP3 and IL-1β proteins decreased (tNF-κB p65 =-34.00--1.71,tNLRP3 =-25.01--16.91,tIL-1β =-73.70--55.14,P ＜ 0.05);the relative expressions of NF-κB p65 and NLRP3 were reduced in a dose-dependent manner (r =0.945,0.926);and the activity of NF-κB were obviously reduced (tNF-κB =-38.68,-614.82,-2 831.40,P ＜ 0.05).Conclusions Sulforaphane effectively alleviates the RILI in lung of mice by downregulating the expressions of inflammatory factor NLRP3.

Objective To analyse the clinical features of pelvic insufficiency fractures (PIF) in patients with cervical cancer after radiotherapy and explore the risk factors affecting its occurrence .Methods 55 cases of patients with cervical cancer that used radia-tion therapy as a single treatment were chosen in our hospital from February 2007 to May 2010 and the clinical features were ana-lysed;The fractures of spine ,sacrum ,sacroiliac joint ,ilium and pubis and femoral were observed and the density of fifth lumbar (L5 ) vertebrae ,left and right sacrum were detected via the CT or MRI (Hounsfield Unit)after 2-year follow-up ,the different factors on the incidence of PIF were explored .Results 12 cases (19 sites) of patients in 55 patients occured PIF after follow-up 2years ,the cumulative incidence was 21 .82% ;the distribution of PIF parts were followed :lumbar vertebrae had 5 cases ,sacral had 5 cases ,pu-bis had 4 cases ,sacroiliac joint had 2 cases ,iliac had 2 cases and femoral head had 1 case .The incidence rate of PIF that density of fifth lumbar vertebrae was ≤130 HU and >130 HU were 16 .36% and 5 .45% respectively ,the PIF′incidence rate that density of left side of sacrum was≤ -35 HU and > -35 HU were 18 .18% and 3 .64% respectively ,the incidence rate of PIF that density of right side of sacrum was ≤ -35 HU and > -35 HU were 20 .00% and 1 .82% respectively ,the density of the three parts all had statistical difference on the incidence of PIF (P<0 .05) .Univariate analysis showed that menopausal status and the average density of CT had statistical effects on PIF (P<0 .05);Multiple analysis showed that the average density of CT was the independent factors affecting PIF′incidence after radiotherapy .Conclusion The patients with cervical cancer may occur pelvic insufficiency fracture af-ter radiotherapy ,and its incidence is related to menopausal status and bone mineral density .

Opioid receptors have drawn highly attention to scientists since they were founded in the 1990s.As a member of G protein-coupled receptor family,opioid peptides are the endogenous ligands.It is well known to us that the basic structure consists of extracellular amino residues,seven transmembrane region and the hydroxyl residues of the cell.In recent years,the progress of science laid the foundation for further studies on the function of delta receptor.Aberrant expression of delta opioid receptor in a variety of tumors,and it plays an important role of the occurrence and development of tumors.This review describes the recent research advances on delta opioid receptor and its association with hepatocellular carcinoma.

Objective To investigate the feature of cerebral glucose metabolism of dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD). Methods Twenty-five DLB patients and Thirty-one PDD patients underwent positron emission tomography(PET) with 18F-fluorodeoxyglucose (18F-FDG) showing glucose metabolism. The region of interest (ROI) was selected from frontal cortex, temporal cortex, parietal cortex, occipital cortex, cerebellum cortex and corpora striata. 18F-FDG metabolism ratios between various cerebral regions and cerebellum cortex were compared as an indicator of regional cerebral glucose metabolic patterns.Results FDG metabolism ratio of frontal cortex, occipital cortex, parietal cortex, temporal cortex and corpus striatum decreased similarly in DLB and PPD (P>0.05). FDG metabolism ratio of occipital cortex decreased more significantly in DLB than in PDD (P<0.01). The decrease of FDG metabolism in corpus striatum of DLB was symmetric. For patients with PDD, FDG metabolism in corpus striatum contralateral to onset side decreased more significantly than that of corpus striatum ipsilateral to onset side (P<0.05). Conclusion There are similarities and discrepancies in cerebral glucose metabolism between DLB and PDD. These features may be useful in differential diagnosis between these two kinds of Lewy body disease.
