Enormous electro-optic effect in paraelectric nanodisordered KTaNbxO crystal.

Recent experiments have revealed that the order of the electro-optic (EO) effect depends on the frequency of electric field in paraelectric nanodisordered KTaNbxO (KTN) crystal. Through the dielectric frequency spectrum under the bias electric field, enormous linear and quadratic EO effects were discovered at the resonance frequencies, which changed the perception that only the quadratic EO effect exists. Applying just a small AC electric field of 6 V/mm, the effective linear EO coefficient reached 478 pm/V at 609 kHz, and the effective quadratic EO coefficient reached 4.

Severity of albuminuria as an early indicator for wound healing in type 2 diabetic foot ulcers.

This study aimed to investigate the relationship between the severity of albuminuria and wound healing in type 2 diabetic foot ulcers. A total of 121 patients with diabetic foot ulcers were recruited from January 2015 to June 2017 and divided into nonproliferation and proliferation groups according to their healing status. Univariate and multivariate logistic regression were performed to assess the risk factors of wound proliferation.

Baseline and early 3D-CUBE volume reconstruction of locally advanced rectal cancer to predict tumor response after neoadjuvant chemotherapy.

Purpose: To explore whether volumetric measurements of 3D-CUBE sequences based on baseline and early treatment time can predict neoadjuvent chemotherapy (NCT) efficacy of locally advanced rectal cancer (LARC).

Material And Method: 73 patients with LARC were enrolled from February 2014 to January 2018. All patients underwent MRIs during the baseline period before NCT (BL-NCT) and the first month of NCT (FM-NCT), and tumor volume (TV) was measured using 3D-CUBE, and tumor volume reduction (TVR) and tumor volume reduction rate (TVRR) were calculated.

Using competing risk and multistate model to estimate the impact of nosocomial infection on length of stay and mortality in burn patients in Southeast China.

Objective: Due to the defects in skin barrier function and immune response, burn patients who survive the acute phase of a burn injury are at a high risk of nosocomial infection (NI). The aim of this study is to evaluate the impacts of NI on length of stay (LOS) and hospital mortality in burn patients using a multistate model.

Design And Setting: A retrospective observational study was conducted in burn unit and intensive care unit in the First Affiliated Hospital of Wenzhou Medical University, Wenzhou, China.

[Carotid artery stenosis treated with modified carotid endarterectomy: report of two cases].

Based on standard carotid endarterectomy, we performed modified carotid endarterectomy in two cases of carotid artery stenosis by changing the direction of the carotid artery incision to avoid restenosis of the internal carotid artery without using a patch. The two patients recovered smoothly without any complications. Compared with eversion or patch endarterectomy, this modified carotid endarterectomy avoids restenosis of the carotid artery and shortens operation time.

Hairy/enhancer of Split Homologue-1 Suppresses Vascular Endothelial Growth Factor-induced Angiogenesis via Downregulation of Osteopontin Expression.

Angiogenesis plays a critical role in the progression and vulnerability of atherosclerotic plaques; however, the orchestration of angiogenesis in atherosclerotic plaque formation remains unclear. The results of microarray analysis, real-time PCR and immunohistochemical analyses showed that Hairy/enhancer of split homologue-1 (Hes-1) expression was significantly decreased, while that of osteopontin (OPN) was increased, in atherosclerotic plaques. Meanwhile, immunofluorescence results demonstrated that both Hes-1 and OPN were expressed in endothelial cells (ECs) of neovessels in atherosclerotic plaques.

[Application of lock-in photocarrier radiometry in solar cells].

Lock-in PCR was introduced to investigate the industrial solar cell. Laser-induced infrared photocarrier radiometry (PCR) is a dynamic near-infrared (NIR) modulated photoluminescence imaging (PL), which has proven to be an effective non-contact methodology for tie measurement of transport properties in semiconductors. Lock-in carrierography (LIC) is a dynamic NIR InGaAs-camera-based photocarrier radiometric PL imaging method recently introduced as an imaging extension of PCR.

Target recognition of ladar range images using even-order Zernike moments.

Ladar range images have attracted considerable attention in automatic target recognition fields. In this paper, Zernike moments (ZMs) are applied to classify the target of the range image from an arbitrary azimuth angle. However, ZMs suffer from high computational costs.

Objective: To investigate the clinical value of local regional administration of urokinase and argatroban through small saphenous vein (SSV) catheter in the treatment of acute deep venous thrombosis in the lower limb (LDVT).

Methods: Fifty-six patients with acute LDVT were prospectively randomized into the study group (21 cases, 24 limbs) and control group (35 cases, 36 limbs) for treatment with urokinase and argatroban regionally administered via the SSV catheter and with the same agents given via the peripheral vein, respectively. The patients were examined for changes in serum fibrinogen (FBG) and D-dimer and the perimeter of the affected limbs, and the complications in relation to the agents were observed.

[Experience with endovenous laser treatment combined with high ligation and Muller's phlebectomy for C3-6 grade primary superficial varicose in the lower limbs].

Objective: To summarize the experience with endovenous laser treatment(EVLT) combined with high ligation and Muller's phlebectomy for primary superficial varicose in the lower limbs.

Methods: In 95 patients with C3-6 grade primary superficial varicose in 146 lower limbs, the extent of varicose was accurately marked, the guiding wires were manipulated precisely, and the proximal great saphenous veins (GSV) were ligated after exsanguinations. The stems of the GSV were ablated with laser with the lower limbs lift up and pressed hard along the stems, and Muller's incisions were carefully planned.
