Objectives This study aimed at finding cut if reperfusion could be identified by long term VLP,using digital Holter ECG.Methods 24 hour 3 channel digital Holter recorders were performed on 38 patients with AMI before thrombolytic therapy,then the patients were divided into successful reperfusion group and unsuccessful reperfusion group.Every parameter was comparied between the two groups.Results VLP parameters showed a gradual improvement in the acute phase of MI in patients with successful reperfusion compared with those of unsuccessful reperfusion and that a significant difference between these two groups became evident from 2～3 hour after thrombolysis.Conclusions Our investigation certifies that successful reperfusion reduces VLP positive rate significantly 2～3 hours after thrombolysis.Thus,long term ventricular late potential may be helpful for identification of the reperfusion in AMI patients.In the mean time,Our study is performed before the formation of myocardial fibrous scar in AMI patients,it breaks up the traditional concept that VLP only developed from the formation of myocardial fibrous scar.

Drug for cholestasis therapy is extremely limited.Ur-sodeoxycholic acid is currently the only FDA approved drug to treat primary biliary cirrhosis,whereas its efficacy is limited to early stage of the disease.Therefore,developing novel drugs re-presents a major goal for both pharmaceutical industry and aca-demic researchers.Targeting nuclear receptors in cholestasis is an intriguing approach since these receptors are critically in-volved in the regulation of bile acid homeostasis.This review summarizes the roles of individual nuclear receptors in cholestasis and evaluates their potential clinical application.

Objective: To study the effect on cytotoxicity and drug resistance by blocking ERCCl gene expression in o-varian cancer cell lines. Methods: ERGC1 antisense expression vector was constructed and transfected into human ovarian cancer cell lines. Northern blotting and Western blotting were used to detect the RNA and protein expression level in the cells. Luciferase assay system was used to reveal the host cell reactivation function. MTT assay was used to study the effect on cytotoxicity and drug resistance in the cell lines. Results: After transfection of the antisense ERCCl, Northern and Western blotting indicated that the RNA and protein expression level of ERCCl was obviously decreased. Luciferease assay showed reduced DNA-damage repair capacity as assessed by host cell reactivation. MTT assay also showed decreased drug resistance to cisplatin in the lines. Conclusion: Transfection of antisense ERCCl may enhance the cisplatin cytotoxicity by disturbing the NER pathway in cisplatin-resistant cell lines.

[Objective]To investigate the relationship of baseline antimullerian hormone(AMH)and live birth rate of IVF/ICSI and further explore the prognostic effect of AMH on live birth rate.[Methods]All non-polycystic ovary patients who underwent their first embryo transfers in our unit and had basal serum AMH evaluated between 2010 and 2015 were evaluated in this retrospective study. Patients were grouped according to their AMH level,i.e. low AMH group with AMH less than 1.1 ng/mL(n = 485),middle AMH group with AMH between 1.1 ng/mL and 7.0 ng/mL (n = 1 989),and high AMH group with AMH higher than 7.0 ng/mL (n=468). For age subgroup analysis,patients were stratified as follow:group A(age≤29 years),group B(30~34 years),group C(35~39 years)and group D(over 40 years). We compared clinical outcomes between AMH groups in different age groups usingunivariate and multivariate analysis. ROC analysis was utilized to assess predictive value of AMH on live birth rate.[Results](1)In both fresh and frozen embryo transfers,baseline AMH was significantly related to clinical outcomes. The lower AMH was,the lower implantation rate,clinical pregnancy rate,and live birth rate. However,higher miscarriage rate was observed. All difference reached statistically significant.(2)In age subgroup analysis,we demonstrated AMH was related to live birth rate in patients in group A,B, and C,regardless of fresh or frozen embryo transferred. In those over 40 years,AMH was related to live birth rate in frozen cycles (P < 0.05)but not fresh cycles(P = 0.092). The further multivariate analysis confirmed the above results after controlling po?tential confounding variables.(3)The AUC of ROC analysis for AMH predicting live birth rate were 0.647,0.633 for fresh and fro?zen cycles respectively.[Conclusion]Baseline AMH as one of excellent ovarian reserve markers ,was significantly related to live birth rate in fresh or frozen cycles. Baseline AMH was an independent prognostic factor of live birth rate,but its predictive value on live birth rate was of limited clinical value.

Purpose To retrospectively analyze and summarize the image features of rare ovarian clear cell carcinoma (OCCC), and to provide basis for clinical diagnosis. Materials and Methods CT and MRI features of 30 cases of OCCC confirmed by pathology were retrospectively analyzed. Sixteen of all the patients underwent pre- and post-contrast CT scan. And 14 patients underwent pre- and post-contrast MRI scans. Results ① CT features: unilateral mass was revealed in 15 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 8 to 23.7 cm, mean (12.86±3.96) cm. One mass was irregular, 4 masses revealed incomplete capsule, and 4 masses had septa in the mass. CT value of cystic part of the mass was 20-30 HU, and which of solid part was 28-53 HU. On post-contrast CT images, the septa and solid component of the mass showed marked enhancement and delay enhancement, while the cystic component showed no enhancement. ② MRI features: Unilateral mass was revealed in 13 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 9.2 to 30.0 cm, mean (14.03±4.72) cm. One mass was irregular, 2 masses revealed incomplete capsule, and 2 masses had septa in the mass. The cystic component showed heterogenous signal intensity on T1WI, and high signal intensity on T2WI. There was no enhancement on post-contrast images. The solid component showed iso-intensity on T1WI, high signal intensity on T2WI, and diffused restricted on diffusion-weighted images. There was markedly enhancement on post-contrast images. ③ Blood supply of the tumor: In 8 cases, the branch of enlarged ipsilateral ovarian artery fed the tumors. In other 16 cases, the masses were surrounded by enlarged ipsilateral ovarian vein. Conclusion The characteristic CT and MRI features of OCCC include: a cystic solid mass with complete capsule; the solid component projects into the cavity, which could be hypervascular and marked enhanced.

Objective To demonstrate the manifestations on positron emission tomographycomputed tomography (PET-CT) at different stages in anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis.Methods PET-CT was performed in 10 patients with anti-NMDAR encephalitis at different clinical stages,and the images were analyzed to investigate the relation of metabolic patterns in the images with clinical presentations.Results Except for normal PET-CT images in 2 patients,images in 8 patients at early stage of the disease showed generally increased 2-[18F] fluoro-2-Deoxy-D-glucose(18F-FDG) uptake at frontal and temporal lobe,basal ganglion and cerebellum,indicating hyper-metabolism in these areas,while 2 of them also had mixture of hyper-and hypo-metabolism in parietal-occipital region.In longitudinal analysis of PET-CT images in these 8 cases,starting at basal ganglion,18 F-FDG uptake gradually decreased bilaterally,prominently at left dominant hemisphere and right cerebellum.Conclusions During the course of anti-NMDAR encephalitis,18F-FDG metabolism markedly increases at early stage and then gradually declines at late stage,at frontal,temporal,parietal and occipital lobes,basal ganglion and cerebellum,predominantly at left dominant hemisphere and right cerebellum.However,in relapsing anti-NMDAR encephalitis,18 F-FDG metabolism in brain does not show these characteristics.

Objective To investigate the regulation on cell cycle related factor such as Cyclins and P21waf/cip1 by inhibiting histone deacetylase(HDAC)with valproic acid sodium(VPA).Methods HepG2 hep-tocellular carcinoma cells.BGC-823 gastric carcinoma cells and MCF-7 breast cancer cells were cultured with O.75-4.00 mmoL/L VPA for 48 h in vivo.and the cell cycle was analyzed by flow cytometry with PI assay.The protein and mRNA expression of Cyclin A,Cyclin D1,Cyclin E and P21waf/cip1 were analyzed by indirect immu-nofluorescence technique and RT-PCR.respectively.Results Compared with control groups,VPA at concen-trations 0.75-4.00 mmol/L exerted a significant inhibiting effect on G1 phase of HepG2,BGC-823 and MCF-7 cells(P<0.001).and the effect was dose dependent.Cyclin A was down-regulated both at mRNA and protein level in HepG2 and BGC-823 cells(P<0.001),but no difference in MCF-7 cells(P>0.05).Cyclin D1 was down-regulated both at mRNA and protein level(P<0.001)and P2lwaf/cip1 was up-regulated both at the mRNA and protein level in the three cell lines(P<0.001);Conversely,protein and mRNA expression of Cyclin E were unchanged upon treatment with VPA(P>0.05).Condusion Acetylization of histone intervened with VPA can regulate Cyclin D1 and P21waf/cip1 expressions obviously.To the expression of Cyclin A,it shows some difference according to the histogenesis and phenotypes of different carcinoma types.But there is not any obvious function on Cyclin E.Down-regulating Cychn D1 and up-regulating P21waf/cip1 may be the common target path-way in the inhibition of cell cycle G1 phase exerted by VPA.

according to the difference of femoral eccentricity on the affected and healthy sides. In the reduction group (30 cases), the difference value was <-5 mm. In the normal group (87 cases), the difference value was -5-5 mm. In the increased group (45 cases), the difference value was > 5 mm. Femoral stem and femoral prosthesis type were compared among different groups. SF-12 scale score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Harris score were evaluated and compared before and after replacement. RESULTS AND CONCLUSION:Standard eccentricity of femoral prosthesis mainly accounted for 77%, 63% and 73% in the reduction group, normal group and increased group, respectively (P > 0.05). No significant difference in average eccentricity was detected in each group between the affected and healthy sides (P> 0.05). WOMAC score was significantly higher after replacement than that before replacement in three groups (P < 0.05). No significant difference in WOMAC score was found among three groups before replacement (P > 0.05). No significant differences in pain and stiffness were detected among three groups after replacement (P > 0.05), and significant differences in physical function were found (P < 0.05). The physical function was highest in the normal group. No significant difference in SF-12 scale score was seen in the three groups before and after replacement (P > 0.05). The physical ability score was elevated after replacement in the three groups (P < 0.05). Mental scores were significantly elevated in reduction and normal groups (P < 0.05). The excelent and good rate of Harris score was significantly higher in the increased group (96%) than in the reduction group (70%) and normal group (87%) (P < 0.05). These findings indicate that the increased eccentricity contributed to the pain easement after total hip arthroplasty and promoted functional recovery. The decreased eccentricity could worsen patient’s pain, and was not conducive to the restoration of joint function after replacement.
