Objective To evaluate the effect of amniotic products after transcervical resection of uterine adhesions (TCRA). Methods This study was carried out in 57 patients with intensive degree of intrauterine adhesions (IUA) who had been treated by TCRA between Jun. 2013 to Jun. 2014. These patients were devided into two groups randomly. In group amnion, 29 patients were placed amniontic scaffold balloon after TCRA;in group balloon, 28 patients were placed Foley′s balloon after TCRA. The two groups′balloons were taken out after TCRA 7 days. All patients were taken artificial cycle treatment. The uterine cavity form and the menstruation of 2 groups were observed in 3 months after TCRA. Results In group amnion, IUA score dropped from 10.1±0.5 preoperatively to 3.2±1.5 postoperative (P<0.01), in group balloon, IUA score dropped from 10.1 ± 0.5 preoperatively to 6.3 ± 2.5 postoperative (P<0.01). In group amnion, the menstrual score increased from 13.3 ± 4.4 preoperatively to 32.6 ± 5.5 postoperative (P<0.01), in group balloon, the menstrual score increased from 11.1±5.8 to 26.5±5.6 (P<0.01). The menstrual improvement of group amnion was better than that of group balloon significantly (P=0.002). In group amnion, the recurrence rate of adhesion was 21%(6/29), in group balloon, the recurrence rate of adhesion was 36%(10/28). There was no significant difference (P=0.248). The pregnancy rate of group amnion was 28%(8/29), the pregnancy rate of group balloon was 21%(6/28). The difference of pregnancy rate in two groups was not significant (P=0.760). Conclusion This small sample observation indicate that amniotic products used in the treatment of intensive IUA could improve menstrual, reduce the recurrence of adhesion, but the impovement of the pregnancy rate should be confirmed by large sample observation.

A novel method for the determination of metallic elements in environmental samples was developed based on the matrix-assisted plasma surface sampling atomic emission spectrometry ( AES system) . A piece of filter paper was used as sample substrate. By direct interaction of the plasma tail plume with the filter paper surface, the filter paper absorbed energy from the plasma source and released combustion heating to the analytes originally present on its surface, thus to promote the atomization and excitation process. Surface sampling was performed in both cases of liquid and solid state analytes. Therefore, no flow injection system was required and sample pretreatment process was simplified. The proposed method provides several advantages, including fast analysis speed ( about 240 samples/h ) , little sample consumption (μL or μg level) , simplicity in instrument design, and also ease of system operation. These advantages made it attractive as a potential miniaturized AES system for in situ and high-throughput elemental analyses. Quantitative analysis of metal ions were achieved in this study for elements Ag, Au, Ba, Cd, Cr, Cu, Eu, La, Mn, Ni, Pb, Sr and Y. Under optimal conditions, the LOD values of the 13 elements ranged from 1. 0 to 88 μg/L. The repeatability, expressed as relative standard deviation ( RSD) from 10 replicates, ranged from 2. 3% to 6. 8%. To validate the proposed method, the system was employed to determine metal elements in standard reference materials of environmental samples. The content of each element was well in agreement with the certified values.

This article presented a series of cases using vascularized interpositional periosteal-connective tissue ( VIP-CT) flap with guide bone regeneration ( GBR) in peri-implant soft and hard tissue reconstuction at the esthet-ic zone of maxillary. Fifteen cases with bone and soft tissue defects underwent VIP-CT flap with GBR in the implant treatment. And the attached gingiva width was evaluated before treatment and six months and eighteen months after the operation. The width of attached gingival of six months and eighteen months after surgery was significantly dif-ferent from the preoperative value (P<0. 05). However, no statistically significant difference could be found at six months and eighteen months postoperative. The application of VIP-CT flap could increase the width of attached gin-giva around implants and the short-term effects were stable and favorable.

GRP78/Bip,which was first identified by scientists in 1977,is a major endoplasmic reticulum (ER)chaperone that has a variety of function.In tumor tissue,GRP78 is high expression and ectopic expression;participate in the development of tumor,ER-stress state and ectopic distribution on the cell surface,in the form of receptors involved in signal transduction. Therefore,GRP78 as an tumor therapeutic targets,biomarkers of tumor and prognosis of tumor biological markers,plays an important role in the tumor research.In recent years,domestic and foreign scholars have found that in the non-cancer disease (viral infectious disease cardiovascular disease diabetes neurodegenerative disease etc),GRP78 is high expression,indicate its application prospect.This article makes a brief overview on the molecular biological characteristics of GRP78,role in tumor pathogenesis and therapeutic significance and application prospect in non-tumor disease.

Objective: To construct a high effective eukaryotic expre ss ing vector containing mcpr1 gene. Methods: mcpr1 gene w as amplified by PCR from the plasmid T-easy/ mcpr1, then PCR product was in serted into eukaryotic expressing vector pcDNA3.1/V5-His B. The positive recomb inant was identified by PCR analysis, HindIII and BamHI restriction analysis and Sequence analysis. Results: A 400 bp DNA fragment was amplified from the recombinant.

Conclusion: The eukaryotic expressed vector pcDNA3.1/V5-His B/ mcpr1 has been successfully reconstructed.

Objective To investigate how the independent components(ICs)energies of multichannel local field potentials(LFPs) code event base on the analysis of ICA of the cortical LFPs of rats. Methods Taking the event point as the zero point, 15-channel LFPs between the span of ±500ms recorded from the prefrontal cortex of rats were decomposed into 15 ICs. The energies of the ICs were computed in a 50-ms window. By sliding the window with step of 25 ms, a dynamic distribution mapping of the 15 ICs' energies was established. ICs with distinctly increased energies during the span of ±200 ms, which indicating that these ICs energies coded event,were selected as the targets. The corresponding channels of these ICs were determined consequently via the inverse transformation of ICA. Results Considering each trail of the repetitious analysis for the same segment of data, the spatial localization of the dominate function region(s) turned out to be relatively stable in spite of the uncertainty of the number and sequence of the target IC(s) due to the ambiguities of the decomposition of ICA.Meanwhile, the analysis results of a series of data segments showed satisfactory correspondence between data segments and dominate function regions. Conclusion The ICs' energies of multichannel LFPs are able to code events in working memories; It is valid for ICA to identify the coding patterns of multichannel LFPs to events; ICA is capable to localize the dominate function regions of event coding with satisfactory robustness.

Objective To discuss the value of video-assisted thoracoscopic repair in the treatment of pectus excavatum in children.Methods Thoracoscopic sternum elevation with an internal steel bar(Nuss procedure) was performed in 45 children with pectus excavatum.Preoperatively,a curved steel bar was prepared and the site of incision and the lowest part of the depression were labeled with methylene blue.Under right-sided thoracoscopic vision,the bar was inserted into the retrosternal tunnel thereby correcting deformity. Results The steel bar was placed safely in all the 45 patients.The operation time was 35~80 min(mean,60 min).The intraoperative blood loss was less than 5 ml.The length of postoperative hospital stay was 4~10 days(mean,7 days).Forty children were followed for 3~30 months(mean,16.5 months).Short-term complications included pneumothorax in 1 patient and pneumonia in 1 patient.Long-term complications included bar shift after 1 year in 1 patient and persistent sternal pain in 2 patients(which had been cured by oral and local analgetic administration).The bar had been removed in 10 children,all of whom had good cosmetic results.Conclusions Video-assisted thoracoscopic Nuss procedure is safe and effective in the management of pectus excavatum in children,with advantages of short operation time,simple performance,satisfactory cosmetic results,and fewer complications.
