Objective To analyze the correlation of serum estradiol (E2),testosterone (T),estradiol/testosterone (E2 /T) ratio and BMD(Bone mineral density), bone turnover markers in postmenopausal women, and then to provide a theoretical basis for the pathogenesis of postmenopausal osteoporosis.It might point to a new diagnostic indicator for postmenopausal osteoporosis (PMOP).MethodsFrom October 2014 to September 2016, 283 cases of postmenopausal women were recruited from the Renmin Hospital of Wuhan University.Bone mineral density was measured by dual energy X-ray absorption apparatus, and the recruiters were classified into three group: normal controls (95 cases), osteopenia (94 cases) and osteoporosis group (94 cases).Serum calium (Ca),alkaline phosphatase (ALP),and propetide of type-Ⅰ procollagen (PINP) and β C-terminal cross-linked telopeptide of type I collagen (β-CTX) were detected by Roche cobas 6000 analyzer.Serum E2 and T were measured by Siemens Advia Centaur XP analyzer.All statistical analyses were carried out using SPSS 15.0 software.Results Compared with the normal controls, Serum E2[(22.65±5.35)pg/ml vs (18.64±6.18 )pg/ml,(17.04±6.73) pg/ml,P<0.01]and E2/T ratio (9.03±3.21 vs 7.44±1.78,6.67±1.50,P=0.01) were significantly decreased in the group of osteopenia and osteoporosis.But the bone turnover marker PINP was significantly increased[(38.92±19.23) ng/ml vs (43.94±15.52) ng/ml,(46.28±19.21) ng/ml,P=0.04].Correlation analysis results showed that serum E2 and E2/T ratio was negatively correlated with PINP (r=-0.273,P<0.05;r=-0.284,P<0.05),but positively associated with total hip BMD(r2=0.053,P=0.001;r2=-0.136,P<0.001).Multiple linear regression analysis showed serum E2 and E2/T ratio could explain 17.6% and 28.9% of the total hip BMD variance after adjustment for age, BMI and years after menopause.The area under curve (AUC) of combined E2 and E2/T as a indicator for the diagnosis of PMOP was 0.824 (95% CI:0.765-0.884,P<0.01), which was significantly better than that of E2 or E2/T (P<0.01) only.Conclusions Serum E2 and E2/T ratio was negatively correlated with PINP, but positively associated with total hip BMD.The decrease of serum E2 and E2/T ratio showed a strong association with PMOP.The combined detection of E2 and E2/T is expected to be a valuable indicator for the prediction of PMOP and to monitor the process of osteoporosis.

Objective To observe the effects of simultaneous bilateral central venous intubation on chest drainage for bilateral malignant pleural effusion induced by primary non-small lung cancer and summarize the nursing measures. Methods Totally 65 patients with bilateral malignant pleural effusion were randomized into experiment group and control group. In the former group, chest drainage was done using bilateral central venous intubation and in the latter, unilateral chest drainage was used. The two groups were compared in terms of effectiveness rate, time for intubation, remission duration and hospitalization. Results The time for remission duration, hospital stay and time for intubation were all significantly shorter than those of the control group (all P<0.05). There were no significances in curative effect and adverse reactions between the two groups. Conclusion Chest drainage using simultaneous bilateral intubation for bilateral malignant pleural effusion induced by primary non-small lung cancer can be effective in shortening the time for remission, intubation and hospitalization. But it causes no more adverse reaction.

Objective To explore the effect of comprehensive rehabilitation combined with self- efficacy training on hemiplegics after stroke. Methods 60 ischemic stroke patients following hemiplegia were divided into three groups: control group 1 (n=20), control group 2 (n=20), and experiment group (n=20). All the patients received routine rehabilitation, the control group 2 received tasks analysis approach,and the experiment group received tasks analysis approach and self-efficacy training. All the patients were evaluated by Fugl-Meyer Assessment (FMA), Berg Balance Scale (BBS), Self- rating Depression Scale (SDS), Self- rating Anxiety Scale (SAS), modified Barthel Index (MBI) and General Self-efficacy Scale (GSES) before and 8 weeks after treatment. Results The scores of FMA, BBS, SDS, SAS, MBI and GSES improved significantly in the experiment group than in the control group 1 and the control group 2 after treatment (P<0.05). Conclusion Comprehensive rehabilitation combined with self-efficacy training can improve the ability of mood and motion, and the activities of daily living of ischemic stroke patient with hemiplegia.

Objective To probe a simple, safe, and minimally invnsive method to treat ectopic pregnancy with preservation of the organs. Methods Superselective catheterization of uterine artery through cannulation of right femoral artery was achieved in 56 patients with ectopic pregnancy. Location of the lesions involved, feeding arteries, and active bleeding were observed on angiography. 150 mg of methylamine neopterin diluted in 100 ml of saline water was infused slowly into the target artery. Small gelatin spongy particles with size of 0.5 mm in diameter were used to embelize the uterine artery until its branches were totally obliterated. Follow-up was undertaken to observe the results of the treatment. Results Suporselective uterine arterial infusion and embolization were successfully performed in all 56 patients without any related complications. Active bleeding in the peritoneum in 33 cases ceased soon after embolization. The embryos in 13 patients were confirmed to have died by ultrasound two days after the procedure. Beta-HCG value dropped to below 5 U/L within two to twelve days. Hemorrhage in the peritoneum dissolved after seven days in all cases. Mixed mass disappeared after one month. Histerosalpingography was performed three months after the procedure in 19 patients and patent fallopians were demonstrated in 11 patients. Conclusions Superselective uterine arterial infusion and embolization is a minimally invasive procedure, which can be used to effectively treat ectopic pregnancy by disabling the ectopic embryo and embelizing leaking arteries with the advantages of preserving the fallopian tubes.

Objective To investigate the effects of neutrophil gelatinase associated lipocalin(NGAL) on renal tubular epithelial cells apoptosis and apoptosis-regulated protein fas,bcl-2 in rat renal ischemia reperfusion injury (IRI).Methods Renal IRI models of rats were established.Rats were randomly divided into 3 groups,including control group,IRI model group and NGAL group.The pathological change of kidney tissue was investigated by hemotoxylin-eosin staining.Renal tubular epithelial cells apoptosis was detected by TUNEL method.Expression of fas and bcl-2 was measured by real-time PCR and Western blotting.Results Compared with IRI model group,NGAL group showed a decreased number of renal tubular epithelial cells apoptosis [(8.6±3.4)/HP vs (20.8±3.7)/HP,P＜0.05],down-regulated fas mRNA (2.34±0.51 vs 6.84±2.34,P＜ 0.05),fas protein (0.65±0.05 vs 0.95±0.08,P＜0.05) and up-regulated bcl-2 protein (0.33±0.05 vs 0.24±0.03,P＜0.05),but the bcl-2 mRNA had no significant change.Conclusion NGAL can protect renal tubular epithelial cells in renal IRI,which may be associated with decreasing cell apoptosis and adjusting protein expression by apoptosis-regulated cytokines.

Objective To explore the effect and mechanism of metastasis associated gene 1 (MTA1) on epithelial-mesenchymal transition(EMT) of esophageal squamous cell carcinoma(ESCC).Methods Lentivirus infection method was used to establish the MTA1 knocking out cell line (LV3-shMTA1-KYSE410) and the MTA1 overexpressing cell line (LVS-MTA1-KYSE450).Western Blot was used to measure the expression of MTA1 and the proteins associated with EMT process.Furthermore,the expression and localization of E-cadherin and Vimentin were observed by immunofluorescence assay under confocal microscope.Finally,the wound healing method was performed to confirm the changes of migration ability of the established cell lines.Results When KYSE-450 cells were overexpressed MTA1,the expression level of E-cadherin was down-regulated while Vimentin was up-regulated,and the migration ability was enhanced (0.91 ± 0.00 vs.0.23 ± 0.04,P ＜0.05).When MTA1 was knocked out in KYSE-410 cells,the results were the opposite (0.19±0.01 vs 0.53±0.01,P ＜0.05).Conclusion Overexpression of MTA1 may promote the process of epithelial-mesenchymal transition and enhance the migration ability of ESCC.

Aim To investigate whether pioglitazone has protective effect against glutamate induced neurotoxicity in cultured cortical neurons and its possible molecular mechanisms underlying pioglitazone's neuroprotective effects.Methods The cortical neurons were taken from newborn rats and used for experiments 7 days after culture.The neurons were randomly divided into control group;glutamate group; glutamate+piogli-tazone group;glutamate+SP600125 group;SP600125 group.Cell viability was determined by MTT.The morphology change of neurons was observed under a fluorescence microscope with fluorescence dye Hoechst 33258.Immunostaining was used to investigate the expression of phospho-ATF2 in neuronal cells.Western blot was performed to investigate the protein level of phospho-JNK1 and total JNK1.Results Pioglitazone markedly reduced the damage of cortical neurons caused by glutamate.Pioglitazone also significantly inhibited glutamate induced up-regulation of phospho-JNK1 protein level and phospho-ATF2 expression.SP600125, an inhibitor of JNK, antagonized the toxicity induced by glutamate.Conclusions Pioglitazone can protect cultured cortical neurons from glutamate induced damage.The protective effect of pioglitazone appears to be associated with inhibiting the c-Jun N-terminal protein kinase signaling pathway.

Objective:To evaluate the effects of amelogenin(AML)on the migration,adhesion and proliferation of periodontal liga-ment stem cells(PDLSCs).Methods:PDLSCs were cultured with AML at 0.25,50 amd 100 μg/ml respectively.The migration, adhesion and proliferation of the cells were examined by wound healing migration assay,transwell migration assay,attachment assay, MTT assay and cell counting,respectively.Results:AML induced the migration of PDLSCs in a dose-dependent manner(P <0.05), increased the adhesion and proliferation of PDLSCs(P <0.05).Conclusion:AML may promote the migration,adhesion and prolifer-ation of PDLSCs.

Objective To investigate the changes in Wnt/β-catenin,bone morphogenic protein (BMP),estrogen receptor (ER) and insulin-like growth factor (IGF) signaling pathways in bone marrow mesenchymal stem cells (BMSCs) differentiation to the osteoblasts after spinal cord injury (SCI) and understand the mechanism of osteoporosis after SCI.Methods Forty 6-week-old male rats were divided into SCI group (n =20) and control group (n =20) according to the random number table.Rats in SCI group were submitted to laminar osteotomy at T10-12 and given lower thoracic cord sharp transection.In control group,rat lower thoracic cord was only exposed without transaction.Femoral bone marrow density (BMD) of rat right side was determined at postoperative 3 months.Femoral bone marrow was harvested from rat left side.After BMSCs osteoblast differentiation,cells were harvested and used for examining expression of genes associated with the signaling pathways in the two groups using microarray technology and real-time PCR analysis.Results BMD in SCI group was significantly lower in the ephiphyses and metaphyses[(0.176 ± 0.017)g/cm2 and (0.170 ±0.016)g/cm2] compared to that in control group [(0.257 ± 0.023) g/cm2 and (0.196 ± 0.013) g/cm2,P ＜0.05].Microarray and PCR analysis revealed Wnt/β-catenin (eg.Wnt1,Wnt3a,Wnt5a,Lrp5,Ctnnb1,Lef1 and Axin),BMP (Tgfb1 and Bmpr1),IGF -1 (eg.IGF1 R,c-fos and c-Jun),and ER (eg.Esr1) signaling pathways in osteoblasts were significantly down-regulated in SCI group compared to these in control group (P ＜ 0.05).Conclusions The Wnt/β-catenin,BMP,ER,and IGF-1 signaling pathways in osteoblasts are significantly down-regulated after SCI,resulting in profound BMD loss.This indicates that these signaling pathways are implicated in the osteoporosis after SCI.
