Abstract
Multispectral optoacoustic tomography (MSOT) is a beneficial technique for diagnosing and analyzing biological samples since it provides meticulous details in anatomy and physiology. However, acquiring high through-plane resolution volumetric MSOT is time-consuming. Here, we propose a deep learning model based on hybrid recurrent and convolutional neural networks to generate sequential cross-sectional images for an MSOT system. This system provides three modalities (MSOT, ultrasound, and optoacoustic imaging of a specific exogenous contrast agent) in a single scan. This study used ICG-conjugated nanoworms particles (NWs-ICG) as the contrast agent. Instead of acquiring seven images with a step size of 0.1 mm, we can receive two images with a step size of 0.6 mm as input for the proposed deep learning model. The deep learning model can generate five other images with a step size of 0.1 mm between these two input images meaning we can reduce acquisition time by approximately 71%.

Abstract
Traditionally, a high-performance microscope with a large numerical aperture is required to acquire high-resolution images. However, the images' size is typically tremendous. Therefore, they are not conveniently managed and transferred across a computer network or stored in a limited computer storage system. As a result, image compression is commonly used to reduce image size resulting in poor image resolution. Here, we demonstrate custom convolution neural networks (CNNs) for both super-resolution image enhancement from low-resolution images and characterization of both cells and nuclei from hematoxylin and eosin (H&E) stained breast cancer histopathological images by using a combination of generator and discriminator networks so-called super-resolution generative adversarial network-based on aggregated residual transformation (SRGAN-ResNeXt) to facilitate cancer diagnosis in low resource settings. The results provide high enhancement in image quality where the peak signal-to-noise ratio and structural similarity of our network results are over 30 dB and 0.93, respectively. The derived performance is superior to the results obtained from both the bicubic interpolation and the well-known SRGAN deep-learning methods. In addition, another custom CNN is used to perform image segmentation from the generated high-resolution breast cancer images derived with our model with an average Intersection over Union of 0.869 and an average dice similarity coefficient of 0.893 for the H&E image segmentation results. Finally, we propose the jointly trained SRGAN-ResNeXt and Inception U-net Models, which applied the weights from the individually trained SRGAN-ResNeXt and inception U-net models as the pre-trained weights for transfer learning. The jointly trained model's results are progressively improved and promising. We anticipate these custom CNNs can help resolve the inaccessibility of advanced microscopes or whole slide imaging (WSI) systems to acquire high-resolution images from low-performance microscopes located in remote-constraint settings.

Abstract
Breast cancer is the leading cause of cancer-associated deaths among women. Techniques for non-invasive breast cancer detection and imaging are urgently needed. Multimodality breast cancer imaging is attractive since it can integrate advantages from several modalities, enabling more accurate cancer detection. In order to accomplish this, indocyanine green (ICG)-conjugated superparamagnetic iron oxide nanoworm (NW-ICG) has been synthesized as a contrast agent. When evaluated in a spontaneous mouse breast cancer model, NW-ICG gave a large tumor to normal tissue contrasts in multiple imaging modalities including magnetic particle imaging, near-infrared fluorescence imaging, and photoacoustic imaging, providing more comprehensive detection and imaging of breast cancer. Thus, NW-ICGs are an attractive platform for non-invasive breast cancer diagnosis.

Abstract
Refractor esophageal stenosis after endoscopic submucosal dissection of early esophageal carcinoma is a difficult clinical problem. To verify the effect of endoscopic radial incision combined local triamcinolone injection to treat refractory esophageal stenosis, we retrospectively analyzed 7 patients diagnosed with refractory esophageal stricture after endoscopic mucosal dissection of early esophageal cancer in this study, of whom 4 male and 3 female patients, aged 50-76 years, with the mean age of 63 years. We performed the endoscopic radial incision in the thickness point of the scar stricture and injected the triamcinolone locally. The results showed it was safe and effective. The follow-up showed no esophageal stenosis occured and no adverse reaction such as hemorrhage, perforation, tumor-recurrence and triamcinolone-allergy occured.

Abstract
Bistable liquid crystal (LC) shutters have attracted much interest due to their low energy consumption and fast response time. In this paper, we demonstrate an electrically tunable/switchable biostable LC light shutter in biological optics through a three-step easy-assembly, inexpensive, multi-channel shutter. The liquid crystal exhibits tunable transparency (100% to 10% compared to the initial light intensity) under different voltages (0 V to 90 V), indicating its tunable potential. By using biomedical images, the response time, resolution, and light intensity changes of the LC under different voltages in three common fluorescence wavelengths are displayed intuitively. Particularly, the shutter's performance in tumor images under the near-infrared band shows its application potential in biomedical imaging fields.

Abstract
Integrative neural interfaces combining neurophysiology and optogenetics with neural imaging provide numerous opportunities for neuroscientists to study the structure and function of neural circuits in the brain. Such a comprehensive interface demands miniature electrode arrays with high transparency, mechanical flexibility, electrical conductivity, and biocompatibility. Conventional transparent microelectrodes made of a single material, such as indium tin oxide (ITO), ultrathin metals, graphene and poly-(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS), hardly possess the desired combination of those properties. Herein, ultra-flexible, highly conductive and fully transparent microscale electrocorticogram (μECoG) electrode arrays made of a PEDOT:PSS-ITO-Ag-ITO assembly are constructed on thin parylene C films. The PEDOT:PSS-ITO-Ag-ITO assembly achieves a maximum ∼14% enhancement in light transmission over a broad spectrum (350-650 nm), a significant reduction in electrochemical impedance by 91.25%, and an increase in charge storage capacitance by 1229.78 μC cm-2. Peeling, bending, and Young's modulus tests verify the enhanced mechanical flexibility and robustness of the multilayer assembly. The μECoG electrodes enable electrical recordings with high signal-to-noise ratios (SNRs) (∼35-36 dB) under different color photostimulations, suggesting that the electrodes are resilient to photon-induced artifacts. In vivo animal experiments confirm that our array can successfully record light-evoked ECoG oscillations from the primary visual cortex (V1) of an anesthetized rat.

Abstract
Objective: To Investigate the application strategy and effect of cuffed tracheostomy tube with inner cannula in the treatment of postoperative complications of laryngeal and hypopharyngeal cancer. Methods: A total of 60 patients with laryngeal and hypopharyngeal cancer occurred serious postoperative complications, including 31 cases of severe postoperative neck infection, 8 cases of dyspnea, 5 cases of massive hemorrhage and 16 cases of seriously intractable aspiration. The tracheal cannula with inner cannula and outer cuff was immediately worn on these patients and the cuff was inflated. Different treatments were carried out according to different complications. The outer cuffs were inflated for patients with severe neck infections to prevent a large amount of neck secretions inhaled to the trachea. Patients with dyspnea immediately received ventilator-assisted ventilation. For those with massive hemorrhage on the wound, doctors should prevent bleeding and stop bleeding under general anesthesia. Patients with severely coughing should perform eating training to prevent food aspiration. The inner cannula was regularly replaced once a month for all of these patients. Results: Through targeted treatment, the complications of 60 patients with cuffed tracheostomy tube with inner cannula were effectively controlled. After dressing change, the neck wounds of 31 patients with neck infection were shrunk or healed. Finally, all of the patients were replaced with metal tracheal tubes. Eight cases with dyspnea were rescued with the symptomatic and related special treatment, and finally replace by metal tracheal tube. Five cases with massive bleeding in the neck wound were successfully rescued and replaced with metal tracheal cannula. Thirteen patients among 16 cases with intractable aspiration were removed the tracheal cannula and other 3 cases of old and severely ill were replaced with metal tracheal cannula. Conclusions: The cuffed tracheostomy tube with inner cannula is of great value in the treatment of severe postoperative complications of laryngeal or hypopharyngeal cancer. It is strongly recommended that the operators should fully understand and use it reasonably after the operation of laryngeal or hypopharyngeal cancer.

Abstract
Objective:To evaluated the clinical anatomy of the inferior thyroid arteries and veins and the safety of clinical application of the modified tracheotomy. Method:Sixty patients who need partial resection or full resection of thyroid cancer and 50 patients with laryngeal or hypopharyngeal cancer required tracheotomy were enrolled in this study. The distribution of the inferior thyroid arteries and veins closely related to tracheotomy is further dissected. The inverted "U" type of tracheal flap tracheotomy was further improved based on anatomical findings. Finally, the further modified tracheotomy was used for clinical practice and compared with the conventional tracheotomy and the inverted "U" type of tracheal flap tracheotomy. Result:Of the 110 cases, the lowest thyroid artery was found in 11 cases, with a rate of 10%. The inferior thyroid vein has 2-4 branches, which originates from the lower lobe or isthmus of the thyroid lateral lobe, descending in the anterior tracheal space. According to the characteristics of the static reflux of the thyroid gland, the lower thyroid vessels are classified into four types: intravenous dry type (28 cases); intravenous double dry without traffic type (43 cases); intravenous double trunk with traffic (28 cases); mixed type (11 cases). At present, the further modified tracheotomy can effectively avoid the rebleeding of the lower thyroid arteries and veins. There were no bleeding and other complications in all cases. Conclusion:It provides a basis for the further modified of tracheotomy based on the clinical anatomy of the inferior thyroid artery and vein, which is closely related to tracheotomy. The further modified tracheotomy has certain advantages than the conventional tracheotomy and the inverted "U" type of tracheal flap tracheotomy.

Abstract
Objective:To investigate the effect of preoperative airway treatment and postoperative asphyxiation preventive measures in patients with tumors invasion in the cervical tracheal. Method:The clinical date of 35 patients with different degree of tumors invasion in the cervical tracheal were analyzed retrospectively. Anesthesia including normal endotracheal intubation anesthesia, awake intubation anesthesia with visual laryngoscope assisted after topical anesthesia, intubation anesthesia with preoperative tracheotomy, intubation anesthesia after transection of trachea and anesthesia with extracoporeal circulation was selected according to the patient's situation such as whether exist forced position, or the extent of dyspnea, or the range of recurrent tumor. Preventive tracheotomy or fistulization was performed according to the patients' tracheal involvement and the choice of operation and general condition during the operation. Result:All 35 patients were successfully anesthetized, 17 of whom had no dyspnea or forced position, this kind patients were all anesthesia successfully, and 3 of them underwent prophylactic tracheotomy. Sixteen cases of nonrecurrent tumor with forced position, 15 patients were accepted awake anesthesia successfully with visual laryngoscope assisted after topical anesthesia, 1 patient who cannot be intubated or done tracheotomy is completed with extracorporeal circulation; prophylactic tracheotomy or tracheostomy was performed in this group. Of 2 cases of recurrent tumor with forced posture, preoperative tracheal intubation failed, 1 case was intubated after emergency transection of trachea, 1 case was successfully intubated by emergency tracheotomy before operation and 2 cases received postoperative tracheostomy. In this study, no serious complications such as massive bleeding, asphyxia and cardiovascular accident occurred after the operation. Conclusion:The preoperative airway management of patients whose tumors involves the cervical tracheal and whether tracheotomy or ostomy need to prevent asphyxia or not should be based on the nature of the tumor such as whether is recurrent, the extent of trachea involvement and whether to merge the OSAHS. Only by considering the various factors that affect the airway synthetically, an effective method can be adopted to ensure the safety of the operation.

Abstract
For studying the melting point depression of metals, isolated metallic nanoparticles embedded in a matrix are usually prepared by mechanical milling. Al is the main available matrix material. In this work, to explore possible alternative matrices for further investigation of melting, mechanically milled metal-nonmetal systems are developed, namely Sn-LiF, Zn-LiF and Zn-Al2O3. The outcome indicates that different matrices do not have a significantly different influence on the melting of Sn and Zn. Theoretical analyses of both the thermodynamics and kinetics of surface-induced melting may support this experimental finding.

Abstract
Several previous studies indicated that genetic polymorphisms in inflammatory factor genes were associated with glioma risk. However, the relationship between the prostaglandin-endoperoxide synthase 2 (PTGS2) genetic polymorphism and glioma remains unclear in the Chinese population. We selected 199 histologically confirmed adult glioma patients and 199 cancer-free controls for the present study and analyzed the distribution of the PTGS2 genotypes and haplotypes. We found that the CC+CT genotype of rs5275 was common in the control group but not in the glioma group (P = 0.033). In addition, we found that the frequency of the C allele was higher in the control group than in the glioma group (P = 0.014). For rs6681231, although we found no significant difference between the 2 groups in genotype distribution, we found that the frequency of the C allele was lower in glioma patients than in control subjects (P = 0.044). We found no significant difference between these 2 groups in the rs689466 genotype and allele distributions. Haplotype analysis suggested that the frequency of the C-A-C haplotype was significantly lower in glioma patients than in control subjects [P = 0.028, odds ratio (OR) = 0.628, 95% confidence interval (CI) = 0.413-0.955]. However, the frequency of the T-A-G haplotype was higher in glioma patients than in control subjects (P = 0.036, OR = 1.418, 95%CI = 1.022-1.967). Therefore, polymorphisms in the PTGS2 gene may be associated with glioma susceptibility in the Chinese population.

Abstract
In the present work, we studied the effect of laetispicine, an amide alkaloid isolated from the stems of Piper laetispicum (Piperaceae), in forced swimming, open field, acetic acid writhing and formalin tests in KM mice to assess antidepressant and antinociceptive effects. A significant and dose-dependent decrease in the immobility time, as evaluated by the forced swimming test, was observed after laetispicine administration (38.18, 39.79, 58.77 and 67.28% decreased at the doses of 5, 10, 20, 40mg/kg, respectively), suggesting an antidepressant effect. Furthermore, in the open field test, laetispicine at the given doses did not alter the number of crossings and rearing, as compared to controls. Results from writhing and formalin tests showed that laetispicine reduced the number of writhing in mice in a dose-dependent manner, attenuated the licking and spiting time of the injected paw in the first phase of formalin test. The antinociceptive effect of laetispicine was not affected by pre-treatment (i.p.) with naloxone (2mg/kg). In conclusion, we showed that laetispicine possessed significant antidepressant and antinociceptive properties, making this drug potentially useful in depression and pain.

Abstract
Single crystalline ZnO nanowires were synthesized by hydrothermal process and then formed nano-tubes by acidic etching these nanowires in acetic solution at 85 degrees C. The nanotube diameter can be easily controlled by dividing the nanowires growth and etching process. The ZnO nanotubes remain single crystalline hexagonal structure after the etching process. The defects existed in the nanowires and the dangling bonds of the nanowires' surface play the important roles for the etching process. An etching model for forming ZnO nanotubes is proposed, which can be proved by our experimental results.

Abstract
The effects of thyroxine (subcutaneous injection) and methimazolum (intubation feeding) on thermosensitive neurons (TSN) in the preoptic/anterior hypothalamic (PO/AH) area in rats were observed. The ratio of warm-sensitive neurons (WSN) to cold-sensitive neurons (CSN) was 1.86:1 and thermo-insensitive neurons (TIN) to thermosensitive neurons (TSN) 1:1.43 in the control group. The ratio of WSN to CSN decreased to 1.20:1 and the ratio of TIN to 1:2.36 in the thyroxine group, while the former increased to 2.40:1 and the latter decreased to 1:1.29 in the methimazolum group. There was significant difference among three groups, (X2 = 9.64, P less than 0.05). Thirty-two percent of neurons (11/34) showed higher firing rates (greater than 15Hz) in the control group, only 8% (3/37) in the thyroxine group and 9% (3/32) in the methimazolum group. In addition, the tolerance of TSN to warming stimulation was obviously lower in both pathological groups, as compared with the control group. The results suggest that a rise or fall of body temperature in rats with subcutaneous injecting thyroxine and intubation feeding methimazolum may be related to the changes of proportion and excitability of PO/AH neurons, and that the disturbance of thyroxine synthesis, release and metabolism may interfere temperature regulation at the level of hypothalamus.
