Effectiveness and safety of Governor vessel acupuncture therapy for post-stroke cognitive impairment: A meta-analysis of randomized controlled trials.

Objective: The purpose of this study was to evaluate the effectiveness of Governor vessel acupuncture (GV Ac) in treating post-stroke cognitive impairment (PSCI).

Methods: There was a total of seven databases examined. Four English databases (Cochrane Library, PubMed, Embase, and Medline) and three Chinese databases (Chinese National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical Databases (VIP), and Wan Fang Database) contain all randomized controlled trials (RCTs) comparing Governor vessel acupuncture to other treatments or none acupuncture for PSCI.

Hyperbaric Oxygen Improves the Survival and Angiogenesis of Fat Grafts after Autologous Fat Transplantation.

Objective: Currently, autologous fat transplantation (AFT) still has a low graft survival rate. Elevation of the AFT graft survival rate is a challenge. This study investigated the effect of hyperbaric oxygen (HBO) on AFT.

Hierarchical porous carbon prepared from biomass through a facile method for supercapacitor applications.

The porous carbon with angstrom-sized pores is important in supercapacitor applications, because of its high pack density and high specific capacitance. In this paper, a facile method is proposed for the preparation of hierarchical porous carbon with high-volume angstrom-sized pores. Onion, as the typical biomass in this research, is used as carbon precursor.

[Effects of Electroacupuncture and Moxibustion Pretreatment on Expressions of HSP 27, HSP 70, HSP 90 at Different Time-points in Rabbits with Myocardial Ischemia-reperfusion Injury].

Objective: To observe the effect of electroacupuncture (EA) and moxibustion (Moxi) pretreatment on expression of myocardial heat shock protein (HSP) in acute myocardial ischemia-reperfusion injury (MIRI) rabbits.

Methods: A total of 72 New Zealand rabbits were randomly divided into 4 groups:sham operation, MIRI model, EA pretreatment and Moxi pretreatment (=18 rabbits in each group) which were further divided into 0, 24 and 48 h (time-point) subgroups (=6 in each). The MIRI model was established by occlusion of the anterior descending branch (ADB) of the left coronary artery for 40 min and reperfusion for 60 min.

Diagnostic accuracy of ultrasonograph guided fine-needle aspiration cytologic in staging of axillary lymph node metastasis in breast cancer patients: a meta-analysis.

Purpose: To evaluate the diagnostic accuracy of ultrasonograph and fine-needle aspiration cytologic examination (USG-FNAC) in the staging of axillary lymph node metastasis in breast cancer patients.

Methods: We conducted an electronic search of the literature addressing the performance of USG-FNAC in diagnosis of axillary lymph node metastasis in databases such as Pubmed, Medline, Embase, Ovid and Cochrane library. We introduced a series of diagnostic test indices to evaluate the performance of USG-FNAC by the random effect model (REM), including sensitivity, specificity, likelihood ratios, and diagnostic odds ratios and area under the curve (AUC).

Lack of association between the CYP1A1 Ile462Val polymorphism and endometrial cancer risk: a meta-analysis.

Purpose: Any association between the CYP1A1 Ile462Val polymorphism and endometrial cancer risk remains inconclusive. For a more precise estimate, we performed the present meta-analysis.

Methods: PUBMED, OVID and EMBASE were searched for the studies which met inclusion criteria.

[Study on electro-degradation of new conjugated polymer PFO-BT15 light emitting diodes].

In the present paper electroluminescence spectrum and Raman spectrum were used to study electro-degradation of polymer light emitting devices (PLEDs) of PFO-BT15, a new and high-efficiency emitting polymer synthesized by the institute of polymer optoelectronic material & devices (IPOM) in South China University of Technology. The PLEDs with a configuration of ITO glass/PEDOT(120 nm)/PFO-BT15(80 nm)/Ba(4 nm)/Al(200 nm) emitted green light at 550 nm when 5 V dc voltage was applied. Three of those devices were used to study the electro-degradation mechanism of PLEDs.

[Study on the oxidation of solutions of aniline and phenol on Ti/SnO2-Sb2O5 electrode by UV-Vis spectroscopy and HPLC].

The electrocatalytic oxidation and degradation of phenol and aniline were studied at Ti/SnO2-Sb2O5 electrode by UV-Vis spectroscopy and high performance liquid chromatography (HPLC). It is shown that hydroquinone, benzoquinone and maleic acid are the same intermediates and products during oxidation of both aniline and phenol. This indicates that the oxidation of the two compounds probably has the same degradation routes.

[Study of poly (3,4-ethylene dioxythiophene) : poly (styrene sulfonate) by in-situ resonance Raman spectroscopy].

Poly (3,4-ethylene dioxythiophene) (PEDOT): Poly (styrene sulfonate) (PSS) has attracted a lot of interest for application in organic electronics due to good stability and high electronic conductivity in its doped state. Indeed, thin layers of PEDOT:PSS was regularly used in light emitting diodes (PLEDs) as hole injection and transportation layer. Here, Doping and dedoping states of PEDOT:PSS were studied by absorbance spectra and Raman spectra.

[Pathomorphological observation of the hypertrophic scar induced by injury to conical structure in female red Duroc pig].

Unlabelled: To further explore the relationship between hypertrophic scar and injury to conical structure of skin and the pathogenesis of hypertrophic scar, and to reproduce an optimal animal model of hypertrophic scar.

Methods: The back of two FRDP pigs were shaved, and a piece of normal skin was harvested for the observation of conical structure of skin. Skin wounds with depth of 0.

[Application of depth-analysis of confocal Raman micro-spectroscopy to chirography identification].

Depth analysis of confocal Raman micro-spectroscopy was applied to chirography identification. The result indicated that depth analysis has potential application to forensic science field, especially in longitudinal identification of ink and inkpad. No matter what the spatial distributions of the signature pen and inkpad are, confocal Raman micro-spectroscopy can longitudinally distinguish those spatial differences.

The authors report Raman degradation study of polymer light-emitting devices under ambient conditions. In order to investigate the chemical degradation reaction in polymer light-emitting diode (PLEDs) devices, the chemical structure of the poly (2-(4-Ethylhexyl) phenyl-1, 4-phenylene vinylene) (P-PPV) polymer was analyzed by micro-Raman spectroscopy during the lifetime of the devices. The evidence for the reduction of conjugation length is provided by Raman spectroscopy.

[Research of image spectrometer using linear variable interference filter].

In the present work we have designed a small-size portable imaging spectrometer using linear variable interference filter, with CCD camera as picture sensor, and micromotion stage to bring along interference filter which scan across every pixel of CCD array. The difference column pixel in the picture which we get at every step is monocolour partial image under different wavelength, with the step by step, these column monocolour pixels change the wavelength. And finally we reassembled these images and get the whole monocolour image with different wavelength.
