Poly(3,4-ethylenedioxythiophene)(PEDOT) is one of the most successful conductive polymers that recently has been used in wearable sensors for human health monitoring. In this work, we prepared a series of PEDOT hybrids consisting of PEDOT, sodium poly(styrene sulfonate)(PSSNa) and polyethylene oxide(PEO), and their preparation could be scaled-up via an adapted solid-state polymerization process. The resistance of the as-prepared PEDOT:PSS/PEO hybrid shows clear temperature response, i.e., it decreases almost linearly with the temperature increase. To understand this phenomenon, the in situ synchrotron radiation wide-and small-angle X-ray scattering(WAXS/SAXS) characterizations were undertaken to study the temperature-dependent microstructure change of the PEDOT:PSS/PEO hybrid. It demonstrated that PEDOT formed conductive paths in the hybrids, which were not destroyed by the PEO crystallization. As temperature increased, the PEO crystals' melting and the accompanying reorganization of PEDOT chains endowed the hybrid sample temperature responsiveness. Based on these fundamental knowledges, the hybrid materials were used to fabricate flexible wearable sensor that showing temperature sensing performance with an accuracy of 1 ℃. These findings shed lights on the scalable manufacturing of wearable sensors for body temperature monitoring.

Mineral Chemistry and Geochemistry of Peridotites from the Zedang and Luobusa Ophiolites, Tibet: Implications for the Evolution of the Neo-Tethys

Journal of Earth Science 2015年第6期26卷 893-910页

作者： Qiang Li Bin Xia Jianfeng Li Lianze Xia Qiangtai Huang Zhongyu Xia School of Marine Sciences Sun Yat-Sen University Qingdao institute of Marine Geology guang zhou institute of Geochemistry Chinese Academy of Sciences Department of Earth Sciences Sun Yat-Sen University

We present a new dataset on platinum group elements（PGEs）, whole-rock major and trace elements, and mineral chemistry for the peridotites from the Zedang and Luobusa ophiolite suites, Tibet, in an attempt to better constrain the petrogenesis of the Zedang and Luobusa ophiolites and the tectonic evolution of the Neo-Tethys. Plots of chondrite-normalized PGE, PGE vs. Mg#, and PGE vs. Al_2O_3 suggest that the lherzolite and harzburgite from Zedang and Luobusa have similar PGE characteristics. The Zedang and Luobusa peridotites display U-shaped REE patterns and are enriched in some incompatible elements, indicative of melt-rock interaction. The PGE characteristics may be attributed to partial melting and heterogeneous melt-rock interaction. Mineral chemistry and whole rock major and trace elements data suggest that lherzolite and harzburgite from Zedang and Luobusa have similar geochemical properties. On the spinel Mg# vs. Cr# plot, the composition of the Zedang and Luobusa peridotites is consistent with both abyssal and subduction-zone peridotites. This study indicates that the Zedang and Luobusa peridotites have a similar origin and evolution path： they could have originated from a normal mid-ocean ridge environment and got refertilization in a supra-subduction zone setting.

Background: Serum immunoglobulin A antibodies against Epstein–Barr virus(EBV), viral capsid antigen(VCA?Ig A) and early antigen(EA?Ig A), are used to screen for nasopharyngeal carcinoma(NPC) in endemic areas. However, their routine use has been questioned because of a lack of specificity. This study aimed to determine the distributions of different subtypes of antibody and to illustrate how the natural variation patterns affect the specificity of screening in non?NPC ***: The distribution of baseline VCA?IgA was analyzed between sexes and across 10?year age groups in 18,286 non?NPC participants using Chi square tests. Fluctuations in the VCA?IgA level were assessed in 1056 non?NPC participants with at least two retests in the first 5?year period(1987–1992) after the initial screening using the Kaplan–Meier ***: The titers of VCA?Ig A increased with age(P < 0.001). Using a previous serological definition of high NPC risk, nasopharyngeal endoscopy and/or nasopharyngeal biopsy would be recommended in 55.5% of the non?NPC partici?pants with an initial VCA?Ig A?positive status and in 20.6% with an initial negative status during the 5?year follow?up. However, seroconversions were common; 85.2% of the participants with a VCA?Ig A?positive status at baseline con?verted to negative, and all VCA?Ig A?negative participants changed to positive at least once during the 5?year follow?up. The EA?Ig A status had a high seroconversion probability(100%) from positive to negative; however, it had a low probability(19.6%) from negative to ***: Age? and sex?specific cutoff titer values for serum anti?EBV antibodies as well as their specific titer fluc?tuation patterns should be considered when defining high NPC risk criteria for follow?up diagnostics and monitoring.

Asian Journal of Andrology 2009年第5期11卷 548-556,I0001,I0002页

作者： Xin Gao Jian-Hua zhou Liao-Yuan Li Jian-guang Qiu Xiao-Yong Pu Department of Urology The Third Affiliated Hospital Sun Yat-Sen University Guangzhou 510630 China

In this study we evaluate the oncological and functional results of the largest cohort of patients in China treated by laparoscopic radical prostatectomy （LRP） and with at least 3 years of follow-up. 126 inconsecutive patients （range 56-78 years, median 62.5） who had an LRP were retrospectively analyzed. The mean prostate specific antigen level and Gleason score was 13.4 ng mL^-1 and 6.4, respectively. Twenty-seven patients had unilateral or bilateral nerve preservation and 29 had pelvic lymphadenectomy. Multivariate analysis was used to adjust for differences in clinical and pathological features when comparing the risk for biochemical progression-free survival （bPFS）. Urinary continence was assessed by incontinence questionnaire and erectile function by the Sexual Health Inventory for Men score. The mean operative duration was 250 min and blood loss 354 mL. Five patients received blood transfusion and nine had complications, including rectal injury （two）, ureteral injury （one）, active bleeding （one）, bladder neck stenosis （two）, paralytic ileus （one）, subcutaneous hematoma （one） and port-site hernia （one）. The overall positive surgical margin rate was 20.6% and correlated with pathological stage and Gleason score respectively （P = 0.03, P 〈 0.001 respectively）. All patients had 〉 3 years of follow-up （range 3-6.75 years, mean 4.6, median 4.75）. At 3 years of follow-up, the overall survival rate was 100% and the bPFS was 81.0% in all patients; 124 patients （98.4%） were continent; 22 of 27 patients （81.5%） who underwent nerve preservation retained erectile function. Our series confirms that LRP is an effective, safe and precise technique at Chinese institution.
