How the xerophytic moss Pogonatum inflexum tolerates desiccation.

KEY MESSAGE: Desiccation-tolerant process of xerophytic moss Pogonatum inflexum were identified through de novo transcriptome assembly , morphological structure and physiology analysis. Pogonatum inflexum (Lindb.) Lac. is a typical xerophytic moss and have been widely used in gardening and micro-landscape. However, the mechanisms underlying desiccation tolerance are still unclear. In this study, morphological,  physiological and trancriptomic analyses of P. inflexum to tolerate desiccation were carried out. Our results indicate that P. inflexum increase osmoregulation substances, shut down photosynthesis, and alter the content of membrane lipid fatty acids in response to desiccation, and the genes involved in these biological processes were changes in expression after desiccation. 12 h is the threshold for P. inflexum to tolerate desiccation and its photosynthesis has not been damaged within 12 h of desiccation and can still recover after rewater. We also proved that the gametocyte of P. inflexum has the ability to absorb and transport water, and contains lignin-synthesis genes in response to tolerant desiccation. Our findings not only explain the mechanisms of P. inflexum during desiccation, but also provide some attractive candidate genes for genetic breeding.

Nonalcoholic Fatty Liver Disease as an Emerging Risk Factor and Potential Intervention Target for Atherosclerotic Cardiovascular Diseases.

ABSTRACT: Nonalcoholic fatty liver disease (NAFLD) is an underappreciated independent risk factor for atherosclerotic cardiovascular diseases (ASCVDs). In recent years, the risk of ASCVD has increased along with the prevalence of NAFLD. ASCVD events are highly prevalent and are the main contributor to death in patients with NAFLD. The association between NAFLD and ASCVD has been validated in numerous observational, cohort, and genetic studies. Most of these studies agree that NAFLD significantly increases the risk of developing atherosclerosis and ASCVD. In addition, the underlying proatherosclerotic mechanisms of NAFLD have been gradually revealed; both disorders share several common pathophysiologic mechanisms including insulin resistance, whereas systemic inflammation and dyslipidemia driven by NAFLD directly promote atherosclerosis. Recently, NAFLD, as an emerging risk enhancer for ASCVD, has attracted attention as a potential treatment target for ASCVD. This brief review aims to illustrate the potential mechanistic insights, present recent clinically relevant investigations, and further explore the emerging therapies such as novel antidiabetic and lipid-lowering agents that could improve NAFLD and reduce ASCVD risk.

Elevated postprandial triglyceride-rich lipoproteins in patients with diabetes and stable coronary artery disease correlated with early renal damage and systemic inflammation.

BACKGROUND: Dyslipidaemia is key in the development of coronary heart disease (CHD) in patients with diabetes mellitus (DM). Accumulated evidence supports that diabetic nephropathy increases the mortality risk of patients with CHD, while the influence of diabetic dyslipidaemia on renal damage in patients with DM and CHD remains unknown. Moreover, recent data indicate that postprandial dyslipidaemia has predictive value in terms of CHD prognosis, especially in patients with DM. The study aimed to determine the relationship of triglyceride-rich lipoproteins (TRLs) after daily Chinese breakfast on systemic inflammation and early renal damage in Chinese patients with DM and SCAD. METHODS: Patients with DM diagnosed with SCAD while in the Department of Cardiology of Shengjing Hospital from September 2016 to February 2017 were enrolled in this study. Fasting and 4-h postprandial blood lipids, fasting blood glucose, glycated haemoglobin, urinary albumin-to-creatinine ratio (UACR), serum interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) concentrations, and other parameters were measured. Fasting and postprandial blood lipid profiles and inflammatory cytokines were analysed using a paired t-test. The association between variables was analysed using Pearson or Spearman bivariate analysis. P < 0.05 was considered to be statistically significant. RESULTS: The study enrolled 44 patients in total. Compared with fasting state, postprandial total cholesterol high-density lipoprotein-cholesterol (HDL-C),low-density lipoprotein-cholesterol (LDL-C) and non-high-density lipoprotein-cholesterol (non-HDL-C) all showed no significant change. Postprandial serum triglyceride (TG) concentration increased significantly compared with that at fasting (1.40 ± 0.40 vs. 2.10 ± 0.94 mmol/L, P < 0.001), as did serum remnant lipoprotein-cholesterol (RLP-C) (0.54 ± 0.18 mmol/L vs. 0.64 ± 0.25 mmol/L). Pearson analysis revealed that serum TG and RLP-C positively correlated before and after breakfast. Moreover, during fasting, positive correlations were observed between TG and serum IL-6, TNF-α, and UACR. Positive correlations were observed between RLP-C and IL-6, UACR under fasting condition, while both TG and RLP-C were positively correlated with postprandial serum IL-6, TNF-α, and UACR concentrations. Finally, positive correlations were observed between UACR and IL-6 and TNF-α concentration under both fasting and postprandial conditions. CONCLUSIONS: An increase in postprandial TRLs was observed in Chinese patients with DM and SCAD after daily breakfast, and this increase may be related to early renal injury via the induction of systemic inflammation.

Enhanced Adjacency Matrix-Based Lightweight Graph Convolution Network for Action Recognition.

Graph convolutional networks (GCNs), which extend convolutional neural networks (CNNs) to non-Euclidean structures, have been utilized to promote skeleton-based human action recognition research and have made substantial progress in doing so. However, there are still some challenges in the construction of recognition models based on GCNs. In this paper, we propose an enhanced adjacency matrix-based graph convolutional network with a combinatorial attention mechanism (CA-EAMGCN) for skeleton-based action recognition. Firstly, an enhanced adjacency matrix is constructed to expand the model's perceptive field of global node features. Secondly, a feature selection fusion module (FSFM) is designed to provide an optimal fusion ratio for multiple input features of the model. Finally, a combinatorial attention mechanism is devised. Specifically, our spatial-temporal (ST) attention module and limb attention module (LAM) are integrated into a multi-input branch and a mainstream network of the proposed model, respectively. Extensive experiments on three large-scale datasets, namely the NTU RGB+D 60, NTU RGB+D 120 and UAV-Human datasets, show that the proposed model takes into account both requirements of light weight and recognition accuracy. This demonstrates the effectiveness of our method.

WiMonitor: Continuous Long-Term Human Vitality Monitoring Using Commodity Wi-Fi Devices.

For a large population of elderly who live alone, a continuous long-term daily monitoring system is critical and imminently needed to enhance the quality of their lives. Continuous monitoring of vitality information (i.e., which area the elder is staying in, the motion state and activity intensity of an elder) is essential for elderly care. In this paper, we use existing commodity Wi-Fi devices to design and implement a long-term device-free human daily vitality system, WiMonitor. Our system can continuously capture the target's vitality information in a multi-room home environment without compromising the privacy of the target. In a continuous 22-day experiment, WiMonitor successfully captures the human vitality information accurately. We believe our system can provide valuable long-term monitoring data for both researchers and health care personnel.

ZnO Composite Graphene Coating Micro-Fiber Interferometer for Ultraviolet Detection.

A simple and reliable ultraviolet sensing method with high sensitivity is proposed. ZnO and ZnO composite graphene are successfully prepared by the hydrothermal method. The optical fiber sensor is fabricated by coating the single-mode-taper multimode-single-mode (STMS) with different shapes of ZnO. The effects of the sensitivity of ultraviolet sensors are further investigated. The results show that the sensor with ZnO nanosheets exhibits a higher sensitivity of 357.85 pm/nW·cm-2 for ultraviolet sensing ranging from 0 to 4 nW/cm2. The ultraviolet characteristic of STMS coated flake ZnO composite graphene has been demonstrated with a sensitivity of 427.76 pm/nW·cm-2. The combination of sensitive materials and optical fiber sensing technology provides a novel and convenient platform for ultraviolet detection technology.

Chronic Kidney Disease Induces Inflammatory CD40+ Monocyte Differentiation via Homocysteine Elevation and DNA Hypomethylation.

RATIONALE: Patients with chronic kidney disease (CKD) develop hyperhomocysteinemia and have a higher cardiovascular mortality than those without hyperhomocysteinemia by 10-fold. OBJECTIVE: We investigated monocyte differentiation in human CKD and cardiovascular disease (CVD). METHODS AND RESULTS: We identified CD40 as a CKD-related monocyte activation gene using CKD-monocyte -mRNA array analysis and classified CD40 monocyte (CD40+CD14+) as a stronger inflammatory subset than the intermediate monocyte (CD14++CD16+) subset. We recruited 27 patients with CVD/CKD and 14 healthy subjects and found that CD40/CD40 classical/CD40 intermediate monocyte (CD40+CD14+/CD40+CD14++CD16-/CD40+CD14++CD16+), plasma homocysteine, S-adenosylhomocysteine, and S-adenosylmethionine levels were higher in CVD and further elevated in CVD+CKD. CD40 and CD40 intermediate subsets were positively correlated with plasma/cellular homocysteine levels, S-adenosylhomocysteine and S-adenosylmethionine but negatively correlated with estimated glomerular filtration rate. Hyperhomocysteinemia was established as a likely mediator for CKD-induced CD40 intermediate monocyte, and reduced S-adenosylhomocysteine/S-adenosylmethionine was established for CKD-induced CD40/CD40 intermediate monocyte. Soluble CD40 ligand, tumor necrosis factor (TNF)-α/interleukin (IL)-6/interferon (IFN)-γ levels were elevated in CVD/CKD. CKD serum/homocysteine/CD40L/increased TNF-α/IL-6/IFN-γ-induced CD40/CD40 intermediate monocyte in peripheral blood monocyte. Homocysteine and CKD serum-induced CD40 monocyte were prevented by neutralizing antibodies against CD40L/TNF-α/IL-6. DNA hypomethylation was found on nuclear factor-κB consensus element in CD40 promoter in white blood cells from patients with CKD with lower S-adenosylmethionine / S-adenosylhomocysteine ratios. Finally, homocysteine inhibited DNA methyltransferase-1 activity and promoted CD40 intermediate monocyte differentiation, which was reversed by folic acid in peripheral blood monocyte. CONCLUSIONS: CD40 monocyte is a novel inflammatory monocyte subset that appears to be a biomarker for CKD severity. Hyperhomocysteinemia mediates CD40 monocyte differentiation via soluble CD40 ligand induction and CD40 DNA hypomethylation in CKD.

Acute myocardial infarction after blunt chest wall trauma with underlying coronary aneurysm: a case report.

BACKGROUND: Kawasaki disease is an acute febrile disease with mucocutaneous and cardiovascular involvement affecting infants and young children. Though coronary artery abnormalities are common in Kawasaki disease, no consensus has been reached regarding the treatment of acute coronary artery diseases in this population. CASE PRESENTATION: We described a case of myocardial infarction triggered by blunt chest wall trauma in a 20 years old girl. She presented with chest pain and breathlessness with brief syncope, lab results and electrocardiogram findings were consistent with acute myocardial infarction. Chest computer tomography (CT) demonstrated coronary artery calcifications and echocardiography revealed multiple giant left anterior descending aneurysms, suggestive of Kawasaki disease. Subsequent contrast enhanced 3 dimensional coronary computer tomography angiography (CTA) confirmed these findings. We managed this young patient with a conservative strategy. The patient remained symptom free during 2-years follow-ups. CONCLUSIONS: Prompt medical treatment for traumatic myocardial infarction even with underlying giant coronary artery aneurysms can successfully preserve left ventricular function and prevent remodeling with good short term prognosis.

Combination therapy analysis of ezetimibe and statins in Chinese patients with acute coronary syndrome and type 2 diabetes.

BACKGROUND: Dyslipidemia management situation in Chinese patients with high risk and very high risk has been demonstrated very low, despite the wide use of statins. The effects and safety of the combined treatment of ezetimibe (EZ) and statins in Chinese patients with acute coronary syndrome (ACS) and type 2 diabetes mellitus (T2DM) remain unknown. METHODS: Chinese Patients with ACS and T2DM were divided into the statins group (n=40) and the combination group of EZ and statins (n=44). In order to evaluate the clinical effects on lipids-lowering, systemic inflammation response and clinical safety, the follow-up of all patients was carried out at day 7th and 30th after treatment. RESULTS: The level of low-density lipoprotein cholesterol (LDL-C) in combination group and statins group was 1.87±0.42 and 2.18±0.58 mmol/L at day 7th, 1.51±0.29 and 1.94±0.49 mmol/L at day 30th, respectively. The control rates of LDL-C level in the combination group and the statins group were 77% and 45% at day 30(th), respectively. There was no significant improvement on high-density lipoprotein cholesterol (HDL-C) level during follow-up. The triglyceride (TG) levels were significantly reduced in both groups, while no obvious difference was observed between two groups. No significant difference on serum high-sensitivity C-reactive protein (hs-CRP) level between two groups was observed. Moreover, we did not observe any significant correlation between serum lipids levels and serum hs-CRP level during follow-up. The liver dysfunction and muscle related side effects (MRSE), creatine kinase (CK) and myopathy were not observed in both groups. CONCLUSION: Our study demonstrated that it is feasible to initiate combination therapy during acute phase for Chinese patients with ACS and T2DM, which can bring more significant effect on LDL-C-lowering and improve the control rate of LDL-C level with good safety.

Severe hyperhomocysteinemia promotes bone marrow-derived and resident inflammatory monocyte differentiation and atherosclerosis in LDLr/CBS-deficient mice.

RATIONALE: Hyperhomocysteinemia (HHcy) accelerates atherosclerosis and increases inflammatory monocytes (MC) in peripheral tissues. However, its causative role in atherosclerosis is not well established and its effect on vascular inflammation has not been studied. The underlying mechanism is unknown. OBJECTIVE: This study examined the causative role of HHcy in atherogenesis and its effect on inflammatory MC differentiation. METHODS AND RESULTS: We generated a novel HHcy and hyperlipidemia mouse model, in which cystathionine ß-synthase (CBS) and low-density lipoprotein receptor (LDLr) genes were deficient (Ldlr(-/-) Cbs(-/+)). Severe HHcy (plasma homocysteine (Hcy)=275 µmol/L) was induced by a high methionine diet containing sufficient basal levels of B vitamins. Plasma Hcy levels were lowered to 46 µmol/L from 244 µmol/L by vitamin supplementation, which elevated plasma folate levels. Bone marrow (BM)-derived cells were traced by the transplantation of BM cells from enhanced green fluorescent protein (EGFP) transgenic mice after sublethal irradiation of the recipient. HHcy accelerated atherosclerosis and promoted Ly6C(high) inflammatory MC differentiation of both BM and tissue origins in the aortas and peripheral tissues. It also elevated plasma levels of TNF-α, IL-6, and MCP-1; increased vessel wall MC accumulation; and increased macrophage maturation. Hcy-lowering therapy reversed HHcy-induced lesion formation, plasma cytokine increase, and blood and vessel inflammatory MC (Ly6C(high+middle)) accumulation. Plasma Hcy levels were positively correlated with plasma levels of proinflammatory cytokines. In primary mouse splenocytes, L-Hcy promoted rIFNγ-induced inflammatory MC differentiation, as well as increased TNF-α, IL-6, and superoxide anion production in inflammatory MC subsets. Antioxidants and folic acid reversed L-Hcy-induced inflammatory MC differentiation and oxidative stress in inflammatory MC subsets. CONCLUSIONS: HHcy causes vessel wall inflammatory MC differentiation and macrophage maturation of both BM and tissue origins, leading to atherosclerosis via an oxidative stress-related mechanism.

Clear cell renal cell carcinoma associated microRNA expression signatures identified by an integrated bioinformatics analysis.

BACKGROUND: Clear cell renal cell carcinoma (ccRCC) represents the most invasive and common adult kidney neoplasm. Mounting evidence suggests that microRNAs (miRNAs) are important regulators of gene expression. But their function in tumourigenesis in this tumour type remains elusive. With the development of high throughput technologies such as microarrays and NGS, aberrant miRNA expression has been widely observed in ccRCC. Systematic and integrative analysis of multiple microRNA expression datasets may reveal potential mechanisms by which microRNAs contribute to ccRCC pathogenesis. METHODS: We collected 5 public microRNA expression datasets in ccRCC versus non-matching normal renal tissues from GEO database and published literatures. We analyzed these data sets with an integrated bioinformatics framework to identify expression signatures. The framework incorporates a novel statistic method for abnormal gene expression detection and an in-house developed predictor to assess the regulatory activity of microRNAs. We then mapped target genes of DE-miRNAs to different databases, such as GO, KEGG, GeneGo etc, for functional enrichment analysis. RESULTS: Using this framework we identified a consistent panel of eleven deregulated miRNAs shared by five independent datasets that can distinguish normal kidney tissues from ccRCC. After comparison with 3 RNA-seq based microRNA profiling studies, we found that our data correlated well with the results of next generation sequencing. We also discovered 14 novel molecular pathways that are likely to play a role in the tumourigenesis of ccRCC. CONCLUSIONS: The integrative framework described in this paper greatly improves the inter-dataset consistency of microRNA expression signatures. Consensus expression profile should be identified at pathway or network level to address the heterogeneity of cancer. The DE-miRNA signature and novel pathways identified herein could provide potential biomarkers for ccRCC that await further validation.

Safety Issues Associated With the Clinical Application of PCSK9 Inhibitors: Current Findings.

Reduction in low-density lipoprotein cholesterol levels is the cornerstone of treatment and prevention of atherosclerotic cardiovascular diseases. Currently, high-intensity statins are being used as the first-line therapy to lower low-density lipoprotein cholesterol levels, as they improve the prognosis of patients with atherosclerotic cardiovascular disease and those in high-risk groups. However, in some patients, the expected reduction in cholesterol is not achieved despite aggressive treatment with statins. Moreover, some patients cannot tolerate the dosage or show poor response or compliance to statins. Therefore, combination therapies with statins and other medications should be considered. Recently, several clinical trials have shown that the use of proprotein convertase subtilisin/kexin type 9 inhibitors with or without statins and/or other lipid-lowering drugs can significantly reduce low-density lipoprotein cholesterol levels, sometimes to extremely low levels. Therefore, to facilitate appropriate prescription of these new lipid-lowering drugs, we systemically evaluated the safety issues associated with these inhibitors and extremely low low-density lipoprotein cholesterol levels.

Research progress on the effects of novel hypoglycemic drugs in diabetes combined with myocardial ischemia/reperfusion injury.

Acute myocardial infarction (AMI) reperfusion is associated with ischemia/reperfusion (I/R) injury, which leads to enlarged myocardial infarction size, poor healing of the infarcted myocardium, and poor left ventricular remodeling, thus increasing the risk of major adverse cardiovascular events (MACEs). Diabetes increases myocardial susceptibility to I/R injury, decreases myocardial responsiveness to cardioprotective strategies, exacerbates myocardial I/R injury, and expands the infarct size of AMI, thereby increasing the incidence of malignant arrhythmias and heart failure. Currently, evidence regarding pharmacological interventions for diabetes combined with AMI and I/R injury is lacking. Traditional hypoglycemic drugs have a limited role in the prevention and treatment of diabetes combined with I/R injury. Current evidence suggests that novel hypoglycemic drugs may exert a preventive effect on diabetes combined with myocardial I/R injury, especially glucagon-like peptide-1 receptor agonists (GLP-1 RA) and sodium-dependent glucose transporter protein 2 inhibitors (SGLT2i), which may increase coronary blood flow, reduce acute thrombosis, attenuate I/R injury, decrease myocardial infarction size, inhibit structural and functional remodeling of the ischemic heart, improve cardiac function, and reduce the occurrence of MACEs of diabetes patients combined with AMI via mechanisms such as reduction of inflammatory response, inhibition of oxidative stress, and improvement of vascular endothelial function. This paper will systematically elaborate the protective role and molecular mechanisms of GLP-1 RA and SGLT2i in diabetes combined with myocardial I/R injury, aiming to provide clinical assistance.

Highly Solvent Resistant Small-Molecule Hole-Transporting Materials for Efficient Perovskite Quantum Dot Light-Emitting Diodes.

Perovskite quantum dot light-emitting diodes (Pe-QLEDs) have been shown as promising candidates for next-generation displays and lightings due to their unique feature of wide color gamut and high color saturation. Hole-transporting materials (HTMs) play crucial roles in the device performance and stability of Pe-QLEDs. However, small-molecule HTMs have been less studied in Pe-QLEDs due to their poor solvent resistance and low hole mobility. In this work, three novel small-molecule HTMs employing benzimidazole as the center core, named X4, X5, and X6, were designed and synthesized for application in Pe-QLEDs. One of the tailored HTM-X6 exhibits excellent solvent resistant ability to the perovskite quantum dot (QD) inks due to its proper solubility and low surface energy. Our result clearly demonstrated that the synergistic effect of poor solubility and low surface energy facilitates the achievement of good solvent resistance to perovskite QD inks. As a result, a promising maximal external quantum efficiency (EQE) of 14.1% is achieved in X6-based CsPbBr3 Pe-QLEDs, which is much higher than that of X4 (9.16%) and X5 (6.60%)-based devices, which is comparable to the PTAA reference (EQE ∼ 15.8%) under the same conditions. To the best of our knowledge, this is the first example that a benzimidazole-based small-molecule HTM demonstrated a good application in Pe-QLEDs. Our work provides new guidance for the rational design of small-molecule HTMs with high solvent resistance for efficient Pe-QLEDs and other photoelectronic devices.

Mouse model of plasma cell mastitis.

BACKGROUND: Plasma cell mastitis is distinct from the common form of mastitis and clinically resembles breast carcinoma. The lesion occurs in non-lactating young women, and the incidence rate is rising. Surgical resection is the main treatment, but cannot prevent recurrence of the disease. Disfigurement or removal of breast after the operations can cause marked physical and psychological distress. The etiology of plasma cell mastitis is unclear up till now. It is therefore necessary to investigate further the underlying immunological changes of the disease. METHODS: The lesions of plasma cell mastitis removed from patients through aseptic operation were mixed with normal saline into homogenate tube machine (homogenate tubes were disinfected and sterilized prior to treatment). The mixture was homogenized at medium speed and grinded in ultrasonic cell disruptor. The homogenate obtained was made into oil emulsion with Freund's adjuvant. Thirty female BALB/c mice (6 weeks after sexual maturity) were divided into five groups A-E: group A was blank control; group B was normal saline control; group C was inoculated with 0.02 ml water-in-oil emulsion; group D was inoculated with 0.04 ml water-in-oil emulsion; group E was complete Freund's adjuvant control. RESULTS: Pathology results showed that mouse mammary gland acinar cells remained integral without any abnormal changes observed in control groups A and B. Experimental groups C and D showed dilation of mouse mammary ductal tissue with a large number of epithelial cells and debris in the lumen, and fibrosis around ducts accompanied by large duct cells, neutrophils, lymphocytes, and especially plasma cell infiltration. Pathological changes were observed in 3 (50%) mice and 5 (83.3%) mice in group C and D respectively. In group E, neutrophil infiltration in mammary gland was observed in 5 mice, but neither infiltration of plasma cells nor other abnormal pathological changes were observed. CONCLUSIONS: The lesions of patient with plasma cell mastitis could make the female BALB/c mice experience the similar clinical and pathological manifestation. High-dose group can successfully establish a mouse model of plasma cell mastitis.

Minimally invasive video-assisted thyroidectomy for the early-stage differential thyroid carcinoma.

BACKGROUND: Minimally invasive video-assisted thyroidectomy (MIVAT), the modified Miccoli's thyroid surgery, is the most widespread minimally invasive technique and has been widely used for treatment of thyroid disease. This study aimed to verify the potential benefits of the modified Miccoli's thyroid surgery, determine the feasibility of the MIVAT for early-stage differential thyroid carcinoma and evaluate the likelihood of the surgical method as a standard operation for early malignant thyroid carcinoma. METHODS: A total of 135 patients were retrospectively compared which included two groups of patients: the first group underwent the conventional thyroidectomy; the other group underwent MIVAT. Patients with thyroid nodule smaller than 20 mm and without previous neck surgery were included while those with wide-ranging and distant metastases of cervical tissues, or any suspected thyroid nodal metastases were excluded for analysis. MIVAT and the central compartment (level VI) lymph nodes dissection (LND) were considered as a new treatment method for this retrospective study. In addition to the comparison of surgical outcomes between the new treatment and the conventional thyroid surgery, other surgical parameters including operative time, operative volume of hemorrhage, incisional length, postoperative volume of drainage, length of hospitalization, accidence of hoarse voice, accidence of bucking, accidence of hypocalcemia and peak angle of cervical axial rotation were also compared. RESULTS: Out of 135 patients, 111 patients underwent conventional thyroid surgery and 24 patients underwent MIVAT plus level VI LND for treatment of early-stage differential malignant carcinoma. Patients who received the new surgical treatment had significantly shorter incisional length (3.1 cm vs. 6.9 cm, p < 0.0001), shorter operative time (109 min vs. 139 min, p = 0.014) and fewer operative hemorrhage (29.5 ml vs. 69.7 ml, p < 0.0001) when compared to the conventional treatment. Postoperative peak angle of cervical axial rotation of patients treated with MIVAT was less than those treated with conventional surgery (L: 31.5° vs. 39.0°, p < 0.0001; R: 31.5° vs. 38.0°, p < 0.0001). Incisional wound infection, postoperative hoarse voice, bucking and hypocalcemia were not observed in all patients. Postoperative analgetica was not required as well. CONCLUSIONS: Compared with conventional thyroid surgery for early-stage differential thyroid carcinoma, the new surgical treatment could be considered as an alternative surgical method for treatment of early-stage thyroid carcinoma since it was feasible, safe and clinically effective with better surgical and cosmetic outcomes.

The History of the Introduction of the Concept of Depression Into China.

This is a thematic historical study on the historical construction of the concept of depression in early modern China. Using an external historical research method, through the analysis of newspaper stories, drug advertisements, and medical texts (textbooks and reference books), it presents the sociocultural context of depression in the late Qing Dynasty and early Republican period and depicts the germination and evolution of the depression from a hazy and ambiguous concept in the late Qing Dynasty to a clear and complete disease entity of Western medicine, at least in the Chinese pharmaceutical market in the 1920s. This article examines the three internal logical clues in the localization of depression in China, namely, (1) the transformation of the disease from a symptom (the symptom of a disease) to a disease (an independent disease entity); (2) the pathological mechanism of depression was first made from the perspective of Traditional Chinese Medicine-"caused by stagnation of liver qi," which was joined later by the pathological mechanism of Western medicine-"caused by brain dysfunction"; (3) the introduction of the knowledge of "depression" presents a pattern of "cross-fertilization" between the West and the East. This study also examines the cultural imagery of depression during its early introduction to China and finds the three stereotypes of the manifestation of depression among the then Chinese public, namely, a feminized disease, a disease that afflicted the intellectual youth who were worried about the country, and the association between the disease and the morbid and distorted state of life of the upper-class literary youth.

De novo transcriptome assembly and analysis of genes involved in desiccation tolerance in Grimmia pilifera.

The anatomically simple plants that transition from the aquatic to the terrestrial have a certain mechanism to deal with the damage caused by the changing living environment. Grimmia pilifera is a type of resurrection plants that can survive a long period of desiccation. To understand the molecular mechanisms of desiccation tolerance, nine cDNA libraries were constructed in triplicate from mRNA obtained from G. pilifera for the 0 h, 6 h and 18 h desiccation treatment. RNA-Seq generated âˆ¼ 666 million reads which were assembled into 135,850 unigenes. The differentially expressed genes (DEGs) were identified between different period of time of desiccation. Gene ontology analysis showed that a significant number of genes involved in water deprivation, chloroplast organization, xyloglucan metabolic process, regulation of signaling pathway. In addition, genes involved in osmotic stress, oxidative stress, accumulation of soluble matter, such as gene encoding antioxidant enzymes, trehalose synthase and channel protein, were up-regulated in response to drought stress. These results will be helpful for further studying on the molecular mechanisms of desiccation responses in G. pilifera.

Fatigue and Sleep Assessment using Digital Sleep Trackers: Insights from a Multi-Device Pilot Study.

For the patient community with neurodegenerative disorders (NDD) and immune-mediated inflammatory diseases (IMID), fatigue and sleep disturbances stand out as two of the most common and disabling symptoms, which mightily impair patient's quality of life. Traditional questionnaire-oriented approaches to reflect such symptoms suffer from recall bias and poor sensitivity to change. By virtue of multiple sensing modalities at home, IDEA-FAST project aims to identify novel digital endpoints of fatigue and sleep disturbances, that are objective, reliable and sensitive to change. This article presents and discusses results from a pilot study of IDEA-FAST to evaluate the feasibility of capturing sleep and fatigue measures from three sleep trackers. Data collected from 143 participants (age range: 21-82) across 6 disease groups and healthy cohort for a period of 9 months, were investigated using our proposed sensor analytical pipeline. The overall performance reveals that the median coverage rate of sleep trackers ranged from 48.3% to 76.9%. Furthermore, the digital measures obtained from each device, indicated a higher association with sleep related patient reported outcomes (PROs) than fatigue related ones, when taking all participants into account.
