Abstract
Diagnosis of disorders of consciousness (DOC) remains a formidable challenge. Deep learning methods have been widely applied in general neurological and psychiatry disorders, while limited in DOC domain. Considering the successful use of resting-state functional MRI (rs-fMRI) for evaluating patients with DOC, this study seeks to explore the conjunction of deep learning techniques and rs-fMRI in precisely detecting awareness in DOC. We initiated our research with a benchmark dataset comprising 140 participants, including 76 unresponsive wakefulness syndrome (UWS), 25 minimally conscious state (MCS), and 39 Controls, from three independent sites. We developed a cascade 3D EfficientNet-B3-based deep learning framework tailored for discriminating MCS from UWS patients, referred to as "DeepDOC", and compared its performance against five state-of-the-art machine learning models. We also included an independent dataset consists of 11 DOC patients to test whether our model could identify patients with cognitive motor dissociation (CMD), in which DOC patients were behaviorally diagnosed unconscious but could be detected conscious by brain computer interface (BCI) method. Our results demonstrate that DeepDOC outperforms the five machine learning models, achieving an area under curve (AUC) value of 0.927 and accuracy of 0.861 for distinguishing MCS from UWS patients. More importantly, DeepDOC excels in CMD identification, achieving an AUC of 1 and accuracy of 0.909. Using gradient-weighted class activation mapping algorithm, we found that the posterior cortex, encompassing the visual cortex, posterior middle temporal gyrus, posterior cingulate cortex, precuneus, and cerebellum, as making a more substantial contribution to classification compared to other brain regions. This research offers a convenient and accurate method for detecting covert awareness in patients with MCS and CMD using rs-fMRI data.

Abstract
The potential influence of pituitary-related hormones (including both pituitary gland and target gland hormones) on functional recovery after traumatic brain injury has been observed. However, the relationship between these hormones and the recovery of consciousness in patients with disorders of consciousness (DOC) remains unclear. In this retrospective and observational study, 208 patients with DOC were recruited. According to the Glasgow Outcome Scale (GOS) scores after 6 months, DOC patients were categorized into two subgroups: a favorable prognosis subgroup (n = 38) comprising those who regained consciousness (GOS ≥ 3), and a poor prognosis subgroup (n = 156) comprising those who remained in DOC (GOS < 3). Comparative analyses of pituitary-related hormone levels between the two subgroups were conducted. Furthermore, a binary logistic regression analysis was conducted to assess the predictive value of pituitary-related hormones for the patients' prognosis. The favorable prognosis subgroup showed a significant increase in Adrenocorticotropic hormone (ACTH) levels (p = 0.036). Moreover, higher ACTH levels and shorter days since injury were significantly associated with a better prognosis, with odds ratios of 0.928 (95% CI = 0.873-0.985, p = 0.014) and 1.015 (95% CI = 1.005-1.026, p = 0.005), respectively. A subsequent receiver operating characteristic analysis demonstrated the potential to predict patients' prognosis with an area under the curve value of 0.78, an overall accuracy of 75.5%, a sensitivity of 77.5%, and a specificity of 66.7%. Our findings indicate that ACTH levels could serve as a clinically valuable and convenient predictor for patients' prognosis.

Abstract
Objective: To analyze and evaluate the expressions and clinical value of tuftelin (TUFT1) and Krüppel-like factor 5 (KLF5) in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) tissues. Method: KLF5 mRNA and TUFT1 mRNA transcriptional status in cancer and non-cancer groups were compared according to the Cancer Genome Atlas (TCGA) database. The differences and prognostic value between the groups were analyzed. Postoperative liver cancer and its paired pericancerous tissues, with the approval of the ethics committee, were collected to build tissue chips. The expression of KLF5 and TUFT1 and their intracellular localization were verified by immunohistochemistry. Tissue expression and clinicopathological characteristics were analyzed by immunoblotting. SPSS software was used to analyze the relationship between SPSS and patient prognosis. Results: The transcription level of TUFT1 or KLF5 mRNA was significantly higher in the HCC group than the non-cancer group (P < 0.001), according to TCGA data. Immunohistochemistry and Western blotting examination confirmed the overexpression of TUFT1 and KLF5 in human HCC tissues, which were mainly localized in the cytoplasm and cell membrane. The positivity rates of TUFT1 and KLF5 were 87.1% ( χ(2) = 18.563, P < 0.001) and 95.2% ( χ(2) = 96.435, P < 0.001) in HCC tissues, and both were significantly higher than those in the adjacent group. The expression intensity was higher in stage III-IV than stage I-II of the International Union Against Cancer standard (P < 0.01). The clinicopathological features showed that the abnormalities of the two were significantly related to HBV infection, tumor size, extrahepatic metastasis, TNM stage, and ascites. Univariate analysis was related to tumor size, HBV infection, and survival. Multivariate analysis was an independent prognostic factor for patients with HCC. Conclusion: TUFT1 and KLF5 may both be novel markers possessing clinical value in the diagnosis and prognosis of HBV-related HCC.

Abstract
OBJECTIVE To investigate the effects of sodium fluoride on the ameloblast and reveal the mechanism of dental fluorosis. MATERIALS AND METHODS Mouse ameloblast-like cell line (ALC) cells were treated with various concentrations of NaF, and subjected to Incucyte, fluorescence immunoassay, transmission electron microscopy, reverse transcription quantitative polymerase chain reaction (RT-qPCR), western blot for autophagy examination, alkaline phosphatase and alizarin red staining for mineralization after osteogenic induction. RESULTS NaF exerts a dose-dependent inhibitory effect on ALC cell growth. TEM and fluorescence immunoassay showed that 1.5 mM or higher concentrations of NaF could induce a fusion of lysosome and mitochondria, finally increasing the number of autophagosome. RT-qPCR and western blot showed that the upregulation of autophagy related gene 13 (ATG13), downregulation of phosphorylated Unc-51-like kinase 1 (p-ULK1) were found in NaF-induced autophagy of ALC cells. The knockdown of ATG13 could rescue it as well as the expression of p-ULK1 and LC3B. Besides, alizarin red staining showed that fluoride under these concentrations could promote the mineralization of ALC. CONCLUSIONS The data show that fluoride in higher concentration can induce autophagy via the p-ULk1/ATG13/LC3B pathway of ALCs than lower ones promote mineralization in vitro, which provides insight into the function of NaF in the autophagy and mineralization of ameloblast.

Abstract
Arousal and awareness are two components of consciousness whose neural mechanisms remain unclear. Spontaneous peaks of global (brain-wide) blood-oxygenation-level-dependent (BOLD) signal have been found to be sensitive to changes in arousal. By contrasting BOLD signals at different arousal levels, we find decreased activation of the ventral posterolateral nucleus (VPL) during transient peaks in the global signal in low arousal and awareness states (non-rapid eye movement sleep and anesthesia) compared to wakefulness and in eyes-closed compared to eyes-open conditions in healthy awake individuals. Intriguingly, VPL-global co-activation remains high in patients with unresponsive wakefulness syndrome (UWS), who exhibit high arousal without awareness, while it reduces in rapid eye movement sleep, a state characterized by low arousal but high awareness. Furthermore, lower co-activation is found in individuals during N3 sleep compared to patients with UWS. These results demonstrate that co-activation of VPL and global activity is critical to arousal but not to awareness.

Abstract
Allergic diseases can notably affect a patient's quality of life. World Health Organization (WHO) has identified these diseases as one of the key areas for research and prevention in the 21st century. Currently, allergen-specific immunotherapy is viewed as a potential treatment approach that could modify the natural progression of allergic diseases, thus being recognized as a crucial tactic in their prevention and treatment. Nonetheless, the broad implementation of allergen-specific immunotherapy in clinical settings continues to confront challenges. One significant issue is the absence of standardized centers for subcutaneous allergen-specific immunotherapy. This article presents several perspectives and recommendations for establishing a standardized subcutaneous allergen-specific immunotherapy center.

Abstract
sn2 Palmitate in human milk plays an important role in the physiological health of infants by reducing mineral loss, improving stool hardness, and relieving constipation. Also, sn-2 palmitate modulates intestinal microbiota. However, it remains unclear whether the effects of sn-2 palmitate on infant gut microbiota are dose-dependent. In this study, we investigated the effects of low, medium, and high doses (600, 1,800, and 5,400 mg/kg body weight, respectively) of sn-2 palmitate on the structure, composition, and metabolic function of intestinal microbes in mice. Our results showed that high doses of sn-2 palmitate significantly modulated α- and β-diversity of the intestinal microbiota. The relative abundance of Lachnospiraceae_NK4A136_group decreased with increasing doses of sn-2 palmitate. In contrast, the abundances of Bacteroidetes phylum, Bacteroides, uncultured_Lachnospiraceae, and uncultured_Muribaculaceae were positively correlated with sn-2 palmitate doses. The number of genes predicted encoding autophagy-yeast, phospholipase D signaling pathway, and pentose and glucuronate interconversion metabolic functions of intestinal microbiota increased with increasing doses of sn-2 palmitate. In addition, low and medium doses of sn-2 palmitate significantly upregulated the arginine and proline metabolic pathways, and high doses of sn-2 palmitate significantly increased purine metabolism. Our results revealed that the effects of sn-2 palmitate intake early in life on the composition and metabolism of the intestinal microbiota of mice showed dose-related differences. The study is expected to provide a scientific basis for the development of infant formulas.

Abstract
Lenvatinib mesylate is an oral receptor tyrosine kinase inhibitor against targets of vascular endothelial growth factor receptors 1-3, fibroblast growth factor receptors 1-4, platelet-derived growth factor receptor α, stem cell growth factor receptor, and rearranged during transfection, et al. Lenvatinib has been approved by the National Medical Products Administration of China on September 4, 2018, for the first-line treatment of patients with unresectable hepatocellular carcinoma who have not received systematic treatment before. Up to February 2023, Lenvatinib has been listed in China for more than 4 years, accumulating a series of post-marketing clinical research evidences. Based on the clinical practice before and after the launch of lenvatinib and referring to the clinical experience of other anti-angiogenesis inhibitors, domestic multidisciplinary experts and scholars adopt the Delphi method to formulate the Chinese Expert Guidance on Overall Application of Lenvatinib in Hepatocellular Carcinoma after repeated discussions and revisions, in order to provide reference for reasonable and effective clinical application of lenvatinib for clinicians.

Abstract
OBJECTIVE This study aimed to investigate the effects of personalized music therapy in combination with medication as a treatment for tinnitus. PATIENTS AND METHODS We retrospectively analyzed a total of 200 patients who were admitted to the Department of Otorhinolaryngology in our hospital from June 2018 to June 2019, with tinnitus as their primary complaint. Patients were divided into four groups based on their individual treatment methods: medication group (patients received medication only, n=40), tinnitus masking (TM) group (patients received medication plus TM, n=38), tinnitus re-training (TRT) group (patients received medication plus TRT, n=35), and personalized group (patients received medication plus personalized music therapy, n=30). The pure-tone audiometry (PTA), loudness visual analogue scale (VAS), and tinnitus handicap inventory (THI) for each patient were analyzed. RESULTS There were statistically significant differences in the THI and VAS scores of all groups before and after treatment (p<0.05). Following nine and twelve months of treatment, the THI and VAS scores of the TRT group and the personalized group were significantly lower than those of the other two groups (p<0.05). The THI and VAS scores of the personalized group were significantly lower than those of the TRT group (p<0.05). Additionally, THI and VAS scores were statistically different at various measurement time points in each group (p<0.05). The clinical effective rate (85.37%) of the personalized group was higher than that of the other three groups (p<0.05). CONCLUSIONS TM, TRT, or personalized music therapy, when combined with medication, are effective in treating patients with tinnitus. Among these methods, personalized music therapy may be the superior treatment after nine months of treatment.

Abstract
Objective: To investigate the incidence rate and risk factors of nonalcoholic fatty liver disease (NAFLD) in patients with schizophrenia (SCZ). Methods: The incidence rate of NAFLD in 115 females with SCZ over 40 years of age with complete clinical data was analyzed with the consent of the Ethics Committee of Nantong Fourth People's Hospital. A physical examination report of healthy subjects (n = 95, female, age 40 years old or older) was taken as the control group. Natural language processing technology was used to extract relevant data from the patient's electronic medical record system. Body mass index, alanine aminotransferase, triglycerides, low-density lipoprotein, leptin, and adiponectin were used to establish a human NAFLD-related model. Logistic regression analysis was used to evaluate the psychiatric symptoms, and physiological and biochemical indexes for the predictive value of NAFLD in female patients with SCZ. Results: The prevalence of NAFLD was significantly higher in the SCZ group (55.7%, 64/115) than that in the control group (26.3%, 25/95) (χ (2) = 18.335, P < 0.001). The prediction model showed that age, alanine aminotransferase, triglycerides, low-density lipoprotein, leptin, adiponectin, and body mass index were significantly correlated with NAFLD in females with SCZ. In the natural language processing search language model, arousal intensity (movements: uncontrolled running behavior) and emotional apathy were strongly linked to female patients with SCZ with NAFLD. Age, alanine aminotransferase, triglycerides, low-density lipoprotein, leptin, and body mass index were risk factors for SCZ to develop NAFLD, and adiponectin levels and uncontrolled running behavior were protective factors. Conclusion: The incidence rate of NAFLD is high in middle-aged and elderly females with SCZ. Natural language processing can help to automatically identify the risk factors for SCZ combined with NAFLD and has predictive and auxiliary diagnostic value.

Abstract
PURPOSE Severe traumatic brain injury (TBI) leads to acute coma and may result in prolonged disorder of consciousness (pDOC). We aimed to determine whether right median nerve electrical stimulation is a safe and effective treatment for accelerating emergence from coma after TBI. METHODS This randomised controlled trial was performed in 22 centres in China. Participants with acute coma at 7-14 days after TBI were randomly assigned (1:1) to either routine therapy and right median nerve electrical stimulation (RMNS group) or routine treatment (control group). The RMNS group received 20 mA, 300 μs, 40 Hz stimulation pulses, lasting 20 s per minutes, 8 h per day, for 2 weeks. The primary outcome was the proportion of patients who regained consciousness 6 months post-injury. The secondary endpoints were Glasgow Coma Scale (GCS), Full Outline of Unresponsiveness scale (FOUR), Coma Recovery Scale-Revised (CRS-R), Disability Rating Scale (DRS) and Glasgow Outcome Scale Extended (GOSE) scores reported as medians on day 28, 3 months and 6 months after injury, and GCS and FOUR scores on day 1 and day 7 during stimulation. Primary analyses were based on the intention-to-treat set. RESULTS Between March 26, 2016, and October 18, 2020, 329 participants were recruited, of whom 167 were randomised to the RMNS group and 162 to the control group. At 6 months post-injury, a higher proportion of patients in the RMNS group regained consciousness compared with the control group (72.5%, n = 121, 95% confidence interval (CI) 65.2-78.7% vs. 56.8%, n = 92, 95% CI 49.1-64.2%, p = 0.004). GOSE at 3 months and 6 months (5 [interquartile range (IQR) 3-7] vs. 4 [IQR 2-6], p = 0.002; 6 [IQR 3-7] vs. 4 [IQR 2-7], p = 0.0005) and FOUR at 28 days (15 [IQR 13-16] vs. 13 [interquartile range (IQR) 11-16], p = 0.002) were significantly increased in the RMNS group compared with the control group. Trajectory analysis showed that significantly more patients in the RMNS group had faster GCS, CRS-R and DRS improvement (p = 0.01, 0.004 and 0.04, respectively). Adverse events were similar in both groups. No serious adverse events were associated with the stimulation device. CONCLUSION Right median nerve electrical stimulation is a possible effective treatment for patients with acute traumatic coma, that will require validation in a confirmatory trial.

Abstract
Objective This study aimed to explore whether olfactory response can be a sign of consciousness and represent higher cognitive processing in patients with disorders of consciousness (DoC) using clinical and electroencephalogram data. Methods Twenty-eight patients with DoC [13 vegetative states (VS)/unresponsive wakefulness syndrome (UWS) and 15 minimally conscious states (MCS)] were divided into two groups: the presence of olfactory response (ORES) group and the absence of olfactory response (N-ORES) group according to behavioral signs from different odors, i.e., vanillin, decanoic acid, and blank stimuli. We recorded an olfactory task-related electroencephalogram (EEG) and analyzed the relative power and functional connectivity at the whole-brain level in patients with DoC and healthy controls (HCs). After three months, the outcomes of DoC patients were followed up using the coma recovery scale-revised (CRS-R). Results A significant relationship was found between olfactory responses and the level of consciousness (χ2(1) = 6.892, p = 0.020). For olfactory EEG, N-ORES patients showed higher theta functional connectivity than ORES patients after stimulation with vanillin (p = 0.029; p = 0.027). Patients with N-ORES showed lower alpha and beta relative powers than HCs at the group level (p = 0.019; p = 0.033). After three months, 62.5% (10/16) of the ORES patients recovered consciousness compared to 16.7% (2/12) in the N-ORES group. The presence of olfactory response was significantly associated with an improvement in consciousness (χ2(1) = 5.882, p = 0.023). Conclusion Olfactory responses should be considered signs of consciousness. The differences in olfactory processing between DoC patients with and without olfactory responses may be a way to explore the neural correlates of olfactory consciousness in these patients. The olfactory response may help in the assessment of consciousness and may contribute to therapeutic orientation.

Abstract
BACKGROUND Repetitive transcranial magnetic stimulation (rTMS), as a non-invasive brain stimulation technique, has shown potentials for consciousness recovery of patients with disorders of consciousness (DoC), as, to a certain extent, it is effective in regulating the excitability of central nervous system. However, it is difficult to achieve satisfactory effect with "one size fits all" rTMS treatment due to different clinical conditions of patients. There is an urgent need to develop individualized strategy to improve the effectiveness of rTMS on patients with DoC. METHODS Our protocol is a randomized double-blind sham-controlled crossover trial that includes 30 DoC patients. Each patient will received 20 sessions, in which 10 sessions will be rTMS-active stimulus, and the other 10 sessions will be sham stimulus, separated by no less than 10 days' washout period. The rTMS-active will include 10 Hz rTMS over the individualized-targeted selection area for each patient according to the different insult regions of the brain. Coma Recovery Scale-Revised (CRS-R) will be used as primary outcome at baseline, after the first stage of stimulation, at the end of the washout period, and after the second stage of stimulation. Secondary outcomes will be measured at the same time, including efficiency, relative spectral power, and functional connectivity of high-density electroencephalograph (EEG). Adverse events will be recorded during the study. DISCUSSION rTMS has obtained grade A evidence in treating patients with several central nervous system diseases, and there has been some evidence showing partial improvement on level of consciousness in DoC patients. However, the effectiveness of rTMS in DoC is only 30~36%, mostly due to the non-specific target selection. In this protocol, we present a double-blind crossover randomized sham-controlled trial based on the individualized-targeted selection strategy that aims to study the effectiveness of rTMS therapy for DoC, and the result may provide new insights to non-invasive brain stimulation.

Abstract
Abstract
Disorders of consciousness are impaired states of consciousness caused by severe brain injuries. Previous resting-state functional magnetic resonance imaging studies have reported abnormal brain network properties at different topological scales in patients with disorders of consciousness by using graph theoretical analysis. However, it is still unclear how inter-regional directed propagation activities affect the topological organization of functional brain networks in patients with disorders of consciousness. To reveal the altered topological organization in patients with disorders of consciousness, we constructed whole-brain directed functional networks by combining functional connectivity analysis and time delay estimation. Then we performed graph theoretical analysis based on the directed functional brain networks at three topological scales, from the nodal scale, the resting-state network scale to the global scale. Finally, the canonical correlation analysis was used to determine the correlations between altered topological properties and clinical scores in the patients with disorders of consciousness. At the nodal scale, we observed decreased in-degree and increased out-degree in the precuneus in the patients with disorders of consciousness. At the resting-state network scale, the patients with disorders of consciousness showed reorganized motif patterns within the default mode network and between the default mode network and other resting-state networks. At the global scale, we found a lower global clustering coefficient in the patients with disorders of consciousness than in the controls. The results of the canonical correlation analysis showed that the abnormal degree and the disrupted motif were significantly correlated with the clinical scores of the patients with disorders of consciousness. Our findings showed that consciousness impairment can be revealed by abnormal directed connection patterns at multiple topological scales in the whole brain, and the disrupted directed connection patterns may serve as clinical biomarkers to assess the dysfunction of patients with disorders of consciousness.

Using task-dependent neuroimaging techniques, recent studies discovered a fraction of patients with disorders of consciousness (DOC) who had no command-following behaviors but showed a clear sign of awareness as healthy controls, which was defined as cognitive motor dissociation (CMD). However, existing task-dependent approaches might fail when CMD patients have cognitive function (e.g., attention, memory) impairments, in which patients with covert awareness cannot perform a specific task accurately and are thus wrongly considered unconscious, which leads to false-negative findings. Recent studies have suggested that sustaining a stable functional organization over time, i.e., high temporal stability, is crucial for supporting consciousness. Thus, temporal stability could be a powerful tool to detect the patient's cognitive functions (e.g., consciousness), while its alteration in the DOC and its capacity for identifying CMD were unclear. The resting-state fMRI (rs-fMRI) study included 119 participants from three independent research sites. A sliding-window approach was used to investigate global and regional temporal stability, which measured how stable the brain's functional architecture was across time. The temporal stability was compared in the first dataset (36/16 DOC/controls), and then a Support Vector Machine (SVM) classifier was built to discriminate DOC from controls. Furthermore, the generalizability of the SVM classifier was tested in the second independent dataset (35/21 DOC/controls). Finally, the SVM classifier was applied to the third independent dataset, where patients underwent rs-fMRI and brain-computer interface assessment (4/7 CMD/potential non-CMD), to test its performance in identifying CMD. Our results showed that global and regional temporal stability was impaired in DOC patients, especially in regions of the cingulo-opercular task control network, default-mode network, fronto-parietal task control network, and salience network. Using temporal stability as the feature, the SVM model not only showed good performance in the first dataset (accuracy = 90%), but also good generalizability in the second dataset (accuracy = 84%). Most importantly, the SVM model generalized well in identifying CMD in the third dataset (accuracy = 91%). Our preliminary findings suggested that temporal stability could be a potential tool to assist in diagnosing CMD. Furthermore, the temporal stability investigated in this study also contributed to a deeper understanding of the neural mechanism of consciousness.

Abstract
The diagnosis and treatment rates of hepatitis B virus (HBV) infection in China in 2020 were 22.1% and 15.0%, respectively, according to the Polaris Observatory HBV Collaborators report. This is still far below the World Health Organization's 2030 hepatitis B elimination target (90% and 80%, respectively, for the diagnosis and treatment rates). Although China has promulgated and implemented a series of policies to eliminate the hepatitis B virus, there are still many HBV infected patients who need to be detected and treated. It has been contoversial whether HBeAg-positive chronic HBV infected-patients with high viral load and normal alanine aminotransferase (ALT), also known as the "immune-tolerant phase," should receive anti-HBV therapy. Hepatologists should pay attention to the patient population known as "immune tolerant," as well as the continuous accumulation of evidence-based medical evidence for early antiviral therapy response. The current focus is on discussing the pros and cons of receiving and recommending anti-HBV therapy at this time for the management of these patients.

Abstract
Background Recent studies have shown that patients with disorders of consciousness (DoC) can benefit from repetitive transcranial magnetic stimulation (rTMS) therapy. The posterior parietal cortex (PPC) is becoming increasingly important in neuroscience research and clinical treatment for DoC as it plays a crucial role in the formation of human consciousness. However, the effect of rTMS on the PPC in improving consciousness recovery remains to be studied. Method We conducted a crossover, randomized, double-blind, sham-controlled clinical study to assess the efficacy and safety of 10 Hz rTMS over the left PPC in unresponsive patients. Twenty patients with unresponsive wakefulness syndrome were recruited. The participants were randomly divided into two groups: one group received active rTMS treatment for 10 consecutive days (n = 10) and the other group received sham treatment for the same period (n = 10). After a 10-day washout period, the groups crossed over and received the opposite treatment. The rTMS protocol involved the delivery of 2000 pulses/day at a frequency of 10 Hz, targeting the left PPC (P3 electrode sites) at 90% of the resting motor threshold. The primary outcome measure was the JFK Coma Recovery Scele-Revised (CRS-R), and evaluations were conducted blindly. EEG power spectrum assessments were also conducted simultaneously before and after each stage of the intervention. Result rTMS-active treatment resulted in a significant improvement in the CRS-R total score (F = 8.443, p = 0.009) and the relative alpha power (F = 11.166, p = 0.004) compared to sham treatment. Furthermore, 8 out of 20 patients classified as rTMS responders showed improvement and evolved to a minimally conscious state (MCS) as a result of active rTMS. The relative alpha power also significantly improved in responders (F = 26.372, p = 0.002) but not in non-responders (F = 0.704, p = 0.421). No adverse effects related to rTMS were reported in the study. Conclusions This study suggests that 10 Hz rTMS over the left PPC can significantly improve functional recovery in unresponsive patients with DoC, with no reported side effects.

Abstract
Nonalcoholic fatty liver disease (nonalcoholic fatty liver disease, NAFLD) or metabolic-associated fatty liver disease, has become the most common chronic liver disease worldwide. In recent years, the relationship between NAFLD and non-coding RNA (ncRNA) has attracted the attention of basic and clinical researchers. Circular RNA (circRNA) is a lipid metabolism-related non-coding RNA (ncRNA) that is highly conserved in eukaryotic cells and resembles but differs from linear ncRNAs at their 5'- and 3'-terminal ends. With tissue-specific and steady expression of endogenous ncRNA, miRNA binding sites are contained on closed and circular nucleoside chains, forming the circRNA-miR-mRNA axis or network with proteins, competing with endogenous RNA sponge-like mechanisms, playing a role in inhibiting or promoting the expression of related target genes, and participating in the progression of NAFLD. This paper reviews the circRNA regulatory mechanism, detection technology, and potential clinical value in NAFLD.

Abstract
For patients with disorders of consciousness, such as unresponsive wakefulness syndrome (UWS) patients and minimally conscious state (MCS) patients, their long treatment cycle and high cost commonly put a heavy burden on the patient's family and society. Therefore, it is vital to accurately diagnose and predict consciousness recovery for such patients. In this paper, we explored the role of the P300 signal based on an audiovisual BCI in the classification and prognosis prediction of patients with disorders of consciousness. This experiment included 18 patients: 10 UWS patients and 8 MCS- patients. At the three-month follow-up, we defined patients with an improved prognosis (from UWS to MCS-, from UWS to MCS+, or from MCS- to MCS+) as "improved patients" and those who stayed in UWS/MCS as "not improved patients". First, we compared and analyzed different types of patients, and the results showed that the P300 detection accuracy rate of "improved" patients was significantly higher than that of "not improved" patients. Furthermore, the P300 detection accuracy of traumatic brain injury (TBI) patients was significantly higher than that of non-traumatic brain injury (NTBI, including acquired brain injury and cerebrovascular disease) patients. We also found that there was a positive linear correlation between P300 detection accuracy and CRS-R score, and patients with higher P300 detection accuracy were likely to achieve higher CRS-R scores. In addition, we found that the patients with higher P300 detection accuracies tend to have better prognosis in this audiovisual BCI. These findings indicate that the detection accuracy of P300 is significantly correlated with the level of consciousness, etiology, and prognosis of patients. P300 can be used to represent the preservation level of consciousness in clinical neurophysiology and predict the possibility of recovery in patients with disorders of consciousness.

Abstract
Clostridium perfringens can produce many kinds of toxins and hydrolase, causing gas gangrene, enteritis and enterotoxemia in both human and animals. It is known that C. perfringens can produce more than 20 toxins and hydrolases. The different toxin types are associated with specific disease types. At present, molecular toxin-typing method by PCR has replaced the traditional serological typing method. In this study, we systematically summarize the types, basic characteristics, pathogenic mechanism and the relationship with disease of C. perfringens toxins to provide evidence for the establishment of rapid detection method, immune antigen screening, antibody preparation and research of related pathogenic mechanism.

Abstract
Objective When regaining consciousness, patients who emerge from a minimally conscious state (EMCS) present with different levels of functional disability, which pose great challenges for treatment. This study investigated the frontoparietal activity in EMCS patients and its effects on functional disability. Materials and methods In this preliminary study, 12 EMCS patients and 12 healthy controls were recruited. We recorded a resting-state scalp electroencephalogram (EEG) for at least 5 min for each participant. Each patient was assessed using the disability rating scale (DRS) to determine the level of functional disability. We analyzed the EEG power spectral density and sensor-level functional connectivity in relation to the patient’s functional disability. Results In the frontoparietal region, EMCS patients demonstrated lower relative beta power (P < 0.01) and higher weighted phase lag index (wPLI) values in the theta (P < 0.01) and gamma (P < 0.01) bands than healthy controls. The frontoparietal theta wPLI values of EMCS patients were positively correlated with the DRS scores (rs = 0.629, P = 0.029). At the whole-brain level, EMCS patients only had higher wPLI values in the theta band (P < 0.01) than healthy controls. The whole-brain theta wPLI values of EMCS patients were also positively correlated with the DRS scores (rs = 0.650, P = 0.022). No significant difference in the power and connectivity between the frontoparietal region and the whole brain in EMCS patients was observed. Conclusion EMCS patients still experience neural dysfunction, especially in the frontoparietal region. However, the theta connectivity in the frontoparietal region did not increase specifically. At the level of the whole brain, the same shift could also be seen. Theta functional connectivity in the whole brain may underlie different levels of functional disability.

Abstract
Objective: To investigate the morphological characteristics of upper airway and laryngopharyngeal reflux in obese patients with obstructive sleep apnea (OSA). Methods: A retrospective analysis was performed on the clinical data of 284 adult patients who underwent polysomnography (PSG) from April 2020 to April 2021 in the Department of Otorhinolaryngology, Head and Neck Surgery, Zhongnan Hospital of Wuhan University, including 83 males and 201 females, aged (32.70±7.74) years. Patients were divided into obese group (n=234) and non-obese group (n=50) according to body mass index (BMI). Patients were divided into mild OSA group, moderate OSA group, severe OSA group and extremely severe OSA group by PSG.The results of sleepiness and laryngopharyngeal reflux questionnaire, nasolaryngoscopy and polysomnography were compared in each group. SPSS (version 22.0) software was used in data analysis. Results: Compared with the non-obese OSA group, the lymphoid hyperplasia of tongue root was more heavy in the obese OSA group, and Mueller's maneuver showed that the left-right lateral collapse of the velopharyngeal plane was more serious. Meanwhile, the scores of reflux symtom index (RSI) and reflux finding score (RFS) in the obese OSA group were significantly increased, and the scores of RSI and RFS increased with the increase of OSA severity. The main respiratory events in obese patients with OSA were obstructive hypopnea, their apnea-hypopnea indices(AHI) during REM (AHIREM) was significantly higher than non-REM (AHINREM), and they had lower average blood oxygen saturation. Yet, there was no significant difference in the lowest blood oxygen saturation between the two groups. Conclusions: Our study suggests that lateral pharyngeal wall stenosis in velopharyngeal plane and the lymphoid hyperplasia of tongue root in glossopharyngeal plane occurs more frequently in obese patients with OSA. Laryngopharyngeal reflux is significantly increased in obese patients, and OSA increases laryngopharyngeal reflux in obese patients.

Abstract
Behavioral assessment of sound localization in the Coma Recovery Scale-Revised (CRS-R) poses a significant challenge due to motor disability in patients with disorders of consciousness (DOC). Brain-computer interfaces (BCIs), which can directly detect brain activities related to external stimuli, may thus provide an approach to assess DOC patients without the need for any physical behavior. In this study, a novel audiovisual BCI system was developed to simulate sound localization evaluation in CRS-R. Specifically, there were two alternatively flashed buttons on the left and right sides of the graphical user interface, one of which was randomly chosen as the target. The auditory stimuli of bell sounds were simultaneously presented by the ipsilateral loudspeaker during the flashing of the target button, which prompted patients to selectively attend to the target button. The recorded electroencephalography data were analyzed in real time to detect event-related potentials evoked by the target and further to determine whether the target was attended to or not. A significant BCI accuracy for a patient implied that he/she had sound localization. Among eighteen patients, eleven and four showed sound localization in the BCI and CRS-R, respectively. Furthermore, all patients showing sound localization in the CRS-R were among those detected by our BCI. The other seven patients who had no sound localization behavior in CRS-R were identified by the BCI assessment, and three of them showed improvements in the second CRS-R assessment after the BCI experiment. Thus, the proposed BCI system is promising for assisting the assessment of sound localization and improving the clinical diagnosis of DOC patients.

Abstract
Music can effectively improve people's emotions, and has now become an effective auxiliary treatment method in modern medicine. With the rapid development of neuroimaging, the relationship between music and brain function has attracted much attention. In this study, we proposed an integrated framework of multi-modal electroencephalogram (EEG) and functional near infrared spectroscopy (fNIRS) from data collection to data analysis to explore the effects of music (especially personal preferred music) on brain activity. During the experiment, each subject was listening to two different kinds of music, namely personal preferred music and neutral music. In analyzing the synchronization signals of EEG and fNIRS, we found that music promotes the activity of the brain (especially the prefrontal lobe), and the activation induced by preferred music is stronger than that of neutral music. For the multi-modal features of EEG and fNIRS, we proposed an improved Normalized-ReliefF method to fuse and optimize them and found that it can effectively improve the accuracy of distinguishing between the brain activity evoked by preferred music and neutral music (up to 98.38%). Our work provides an objective reference based on neuroimaging for the research and application of personalized music therapy.

Abstract
BACKGROUND Tumor mutational burden (TMB) measurements aid in identifying patients who are likely to benefit from immunotherapy; however, there is empirical variability across panel assays and factors contributing to this variability have not been comprehensively investigated. Identifying sources of variability can help facilitate comparability across different panel assays, which may aid in broader adoption of panel assays and development of clinical applications. MATERIALS AND METHODS Twenty-nine tumor samples and 10 human-derived cell lines were processed and distributed to 16 laboratories; each used their own bioinformatics pipelines to calculate TMB and compare to whole exome results. Additionally, theoretical positive percent agreement (PPA) and negative percent agreement (NPA) of TMB were estimated. The impact of filtering pathogenic and germline variants on TMB estimates was assessed. Calibration curves specific to each panel assay were developed to facilitate translation of panel TMB values to whole exome sequencing (WES) TMB values. RESULTS Panel sizes >667 Kb are necessary to maintain adequate PPA and NPA for calling TMB high versus TMB low across the range of cut-offs used in practice. Failure to filter out pathogenic variants when estimating panel TMB resulted in overestimating TMB relative to WES for all assays. Filtering out potential germline variants at >0% population minor allele frequency resulted in the strongest correlation to WES TMB. Application of a calibration approach derived from The Cancer Genome Atlas data, tailored to each panel assay, reduced the spread of panel TMB values around the WES TMB as reflected in lower root mean squared error (RMSE) for 26/29 (90%) of the clinical samples. CONCLUSIONS Estimation of TMB varies across different panels, with panel size, gene content, and bioinformatics pipelines contributing to empirical variability. Statistical calibration can achieve more consistent results across panels and allows for comparison of TMB values across various panel assays. To promote reproducibility and comparability across assays, a software tool was developed and made publicly available.

Abstract
Objective: To improve the diagnosis and treatment of pulmonary epithelioid hemangioendothelioma (P-EHE). Methods: Sixteen patients diagnosed with P-EHE in Fuzhou Pulmonary Hospital of Fujian Province from January 2009 to July 2020 were collected. Their gender, age, imaging findings, pathological characteristics, treatment protocols, survival and other clinical data were summarized and analyzed. Results: The ratio of male to female among the 16 patients was 1∶1; and the average age of onset was 47.75 years. Most cases of PEHE (9/16) were found by physical examination, while some cases developed respiratory symptoms such as cough, sputum, shortness of breath, hemoptysis, chest pain, etc. (7/16). In most patients the lesions were localized to the lungs (11/16), while bone metastasis (1/16), lymph node metastasis (1/16), and pleural metastasis (4/16) also occurred. The pathological tissues were obtained mainly through surgical thoracoscopy. Chest CT images showed multiple nodules in both lungs, with most of the nodules less than 2.0 cm in diameter, and calcifications were seen, while solitary nodules and masses were rare, and pleural metastases could be manifested as pleural thickening and pleural effusion. The pathological findings were well-defined eosinophilic nodules with irregularly arranged nest-like structures. Those eosinophilic nodules had few central cells and abundant peripheral cells, which extended into the alveolar cavity like papillae. The tumor cells were epithelioid with small atypia, and vacuoles and red blood cells could be seen in the cytoplasm of individual tumor cells. Immunohistochemically, the tumor cells were positive to CD34, CD31, Factor Ⅷ andvimentin (VIM). Follow-up of 0.5 to 11 years showed that four patients died, two lost to follow-up, and the rest of the patients were in good condition, with a median overall survival (OS) of 4.58 years. Conclusions: PEHE is a rare low-grade lung tumor with no specific clinical manifestations. It can be diagnosed with chest imaging and pathological immunohistochemistry. Moreover, there is currently no standard treatment for PEHE, and most patients have a good prognosis.

Abstract
Heterotrimeric G proteins act as molecular switches to participate in transmitting various stimuli signals from outside of cells. G proteins have three subunits, Gα, Gβ and Gγ, which function mutually to modulate many biological processes in plants, including plant growth and development, as well as biotic and abiotic stress responses. In plants, the number of Gγ subunits is larger than that of the α and β subunits. Based on recent breakthroughs in studies of plant G protein signal perception, transduction and downstream effectors, this review summarizes and analyses the connections between different subunits and the interactions of G proteins with other signalling pathways, especially in plant biotic and abiotic stress responses. Based on current progress and unresolved questions in the field, we also suggest future research directions on G proteins in plants.

Abstract
Oral mucositis and taste dysfunction are frequently complained by patients with head and neck cancer receiving radiotherapy, challenging the clinical outcome of cancer treatment. Recent studies have indicated the protective role of Wnt/β-catenin signaling in radiation-induced oral mucositis (RIOM) and its pivotal role in the development and self-renewal of taste buds. The current study hypothesizes that lithium chloride (LiCl), a potent activator of the Wnt/β-catenin signaling pathway, can promote the postirradiation restoration of oral mucosa integrity and taste function. To validate this hypothesis, we established a RIOM mouse model and evaluated the treatment efficacy of LiCl on oral mucositis and taste dysfunction in comparison with keratinocyte growth factor (KGF), an agent approved by the US Food and Drug Administration for oral mucositis. The results showed that LiCl alleviated the weight loss and tongue ulceration of RIOM mice, promoted proliferation of basal epithelial cells, and inhibited epithelial-mesenchymal transition in tongue mucosa. More important, elevated taste bud renewal and dysgeusia recovery toward sweetness were observed in RIOM mice treated with LiCl as compared to those treated by KGF. Collectively, our data demonstrate that LiCl can mitigate oral mucositis and rescue taste alteration induced by irradiation, and activation of Wnt/β-catenin signaling may represent a promising therapy to improve the quality of life of patients receiving radiotherapy.

Abstract
Precise quantitative delineation of tumor hypoxia is essential in radiation therapy treatment planning to improve the treatment efficacy by targeting hypoxic sub-volumes. We developed a combined imaging system of positron emission tomography (PET) and electron para-magnetic resonance imaging (EPRI) of molecular oxygen to investigate the accuracy of PET imaging in assessing tumor hypoxia. The PET/EPRI combined imaging system aims to use EPRI to precisely measure the oxygen partial pressure in tissues. This will evaluate the validity of PET hypoxic tumor imaging by (near) simultaneously acquired EPRI as ground truth. The combined imaging system was constructed by integrating a small animal PET scanner (inner ring diameter 62 mm and axial field of view 25.6 mm) and an EPRI subsystem (field strength 25 mT and resonant frequency 700 MHz). The compatibility between the PET and EPRI subsystems were tested with both phantom and animal imaging. Hypoxic imaging on a tumor mouse model using 18F-fluoromisonidazole radio-tracer was conducted with the developed PET/EPRI system. We report the development and initial imaging results obtained from the PET/EPRI combined imaging system.

Abstract
Idiopathic condylar resorption (ICR) is an aggressive form of temporomandibular joint disease that most frequently presents in adolescent girls during the pubertal growth spurt. Although numerous studies have indicated that the etiopathogenesis of ICR may be related to estrogen deficiency, the decisive role of estrogens remains controversial, and other sex hormone disturbances have not yet been investigated in this regard. Therefore, the aim of this study was to ascertain the role of serum estrogen levels and also the roles of other sex hormones in the pathogenesis of ICR. Ninety-four ICR patients and 324 disc displacement (DD) patients, of both sexes, were enrolled. Information on menstruation and serum levels of follicle-stimulating hormone, luteinizing hormone, prolactin, 17β-estradiol (E2), testosterone, and progesterone were recorded and analyzed. The results showed that female ICR patients had normal puberty onset, within the average age range. Use of oral contraceptives and other menstruation-regulating pharmaceuticals was similar in the two groups. Of note, neither serum E2 levels nor those of the other sex hormones differed significantly between female ICR and DD patients. However, male ICR patients had significantly increased serum testosterone levels (P=0.002) and relatively higher E2 levels (P=0.095) compared to DD patients. This study found that reduced serum E2 did not contribute to ICR; instead, systemic testosterone disturbances were found to be related to ICR.

Abstract
Whether to initiate antiviral therapy in chronic hepatitis B virus (HBV) infected population with normal alanine aminotransferase (ALT) is hot and difficult issue. Improvements in drug availability and affordability have paved the way for more data, which may become a medium for confirming whether this population needs antiviral treatment. Regardless of whether HBeAg is positive or negative, there are still a considerable number of patients with chronic HBV infection with normal ALT, who have obvious liver inflammation, fibrosis or cirrhosis and need to start antiviral therapy. Liver biopsy or non-invasive techniques can be used as diagnostic tools to begin an early treatment in population with liver fibrosis and inflammation.

Abstract
OBJECTIVE To investigate the effects of ET-1 and TNF-α levels on cardiac function and prognosis in rats with chronic heart failure (CHF), to provide reference for clinical practice. MATERIALS AND METHODS 120 SD rats were randomly divided into healthy group (n=60) and heart failure group (n=60). Rats from heart failure group were made into CHF models by an intraperitoneal injection of adriamycin. According to the average serum levels of ET-1 and TNF-α, 30 rats with higher level were enrolled in high expression subgroup, while 30 rats with lower level were enrolled in low expression subgroup. The sandwich enzyme-linked immunosorbent assay (ELISA) was employed to determine the ET-1 and TNF-α in rats from healthy group and heart failure group. Doppler echocardiography was used to measure the left ventricular ejection fraction, heart rate, and aortic diameter. After the death of heart failure rats, the total heart mass and left ventricle mass were measured and compared with those of the healthy rats. The serum levels of ET-1 and TNF-α were monitored to explore the influence of ET-1 and TNF-α levels on the prognosis of rats from study group. RESULTS The total heart mass and left ventricle mass of the heart failure group were higher than those of healthy group (p<0.05). The total heart mass and left ventricle mass of the low expression subgroup were lower than those of high expression subgroup (p<0.05). CONCLUSIONS The serum levels of ET-1 and TNF-α are higher than those in healthy rats. CHF rats with higher serum levels of ET-1 and TNF-α have a worse heart function and survival. Serum levels of ET-1 and TNF-α can be used as predictors of cardiac function and prognosis in CHF rats, providing references for clinical practice.

Abstract
Chronic hepatitis B virus (HBV) infection remains a major world public health problem. Current guidelines of chronic hepatitis B (CHB) suggest the clinical cure as the ideal thearapeutic goal. Although the optimization of the existing antiviral treatment can make some patients achieve clinical cure, but for most patients with chronic hepatitis B, it is difficult to achieve clinical cure according to the existing antiviral treatment plan. The medical community has begun to work together to seek new treatment strategies, especially the immune intervention measures aimed at restoring the immune response in the liver microenvironment. Notably, immune antiviral response plays a crucial role in HBV clearance, and the clinical cure of chronic hepatitis B is finally achieved through the optimized combination of antiviral and immunomodulatory drugs.

Abstract
BACKGROUND: Acupuncture can effectively alleviate the nasal symptoms of allergic rhinitis (AR); however, the mechanism is unclear. Previous studies suggested it may be related to improve hypothalamus-pituitary-adrenal (HPA) axis dysfunction. MATERIALS and METHODS: The study was a randomised controlled trial including ninety patients with moderate to severe persis- tent AR. Subjects were randomised 1:1:1 to the 8-weeks treatment with mind-regulating acupuncture combined with intranasal glucocorticosteroids (INGC), conventional acupuncture combined with INGC and INGC alone (MA, CA, GC respectively). The primary outcome was the change from baseline in the Visual Analogue Scale (VAS) score of nasal symptoms. Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) score was a key secondary outcome. The levels of corticotrophin releasing hormone (CRH), cortisol (COR) and adrenocorticotropic hormone (ACTH) were also analysed. RESULTS: MA, CA and GC reduced VAS score and total RQLQ by a similar degree, but the sleep domain of RQLQ significantly impro- ved in MA and CA compared to GC. Meanwhile, the COR and ACTH level increased, and CRH level decreased after treatment in MA and CA, but the changes showed no difference among the three groups after Bonferroni correction. CONCLUSIONS: Although acupuncture combined with INGC may have potential effect on sleep quality, the combination therapy cannot further improve nasal symptoms or RQLQ compared to INGC alone in AR patients. The influence of acupuncture on HPA axis needs to be further explored.

Abstract
Abstract
Introduction/Objective
A liposarcoma is a tumor derived from primitive mesenchymal cells undergoing adipose differentiation. Liposarcomas are uncommon in childhood, representing only about 2% of childhood sarcomas. Among liposarcomas, is a very rare subtype, the so-called ‘pleomorphic myxoid liposarcoma’ which has extensive myxoid changes and scattered pleomorphic cells. Here we report an autopsy case of an extensively metastatic pleomorphic myxoid liposarcoma.
Methods
A 12 year-old, African-American boy presented in the ED with ascites and shortness of breath, who later expired despite resuscitation. Autopsy finding showed a primary lesion in the left superior orbital fissure with diffuse metastasis to liver, replacing most of the liver parenchyma (liver weigh 8500 g). Metastatic foci are also present in gallbladder, pancreas, large intestine, bilateral lungs, and inner and outer surfaces of cranium. Histologically, tumor at all sites shows similar morphology, revealing scattered pleomorphic lipoblasts and a myxoid background with arborizing vasculature. Lipoblasts show indented and distorted nuclei and cytoplasmic vacuoles.
Immunohistochemically the tumor cells are immunoreactive for p16 (diffusely and strongly) (Figure, D) and S100 (weakly) and negative for AE1/AE3, myogenin, synaptophysin, GFAP, EMA, and CD34. FISH was negative for MDM2 and t(12;16)(q13;p11.2) FUS-DDIT3 rearrangement, ruling out conventional myxoid liposarcoma.
Conclusion
This case shows the aggressive nature of a poorly studied entity in an uncommon age group and emphasize the need to study childhood liposarcomas in more detail.

Abstract
Abstract
Introduction/Objective
Duodenal epithelial polyps are reported in up to 3% of patients referred for upper endoscopy. Most include non-neoplastic lesions such as Brunner gland nodule/polyp and pancreatic or gastric heterotopia.
Neoplastic lesions such as pyloric gland adenomas (PGA) are less frequently encountered and have the propensity to progress to adenocarcinoma. Herein we report a duodenal submucosal glandular lesion that has a morphologic resemblance to PGA, but very different in several aspects. We compare and contrast the characteristics of these two lesions.
Methods
This was a 63-year-old man referred for an upper GI endoscopy for complaints of indigestion, dyspepsia, and weight fluctuation. Endoscopy showed a 13 mm polypoid lesion in the second portion of the duodenum, opposite to and separate from the ampulla. An en-bloc hot snare was used to resect the polyp. Histopathologic examination showed features reminiscent of PGA, namely a complex submucosal proliferation of tightly packed variably dilated glands and villous fronds lined by a monolayer of columnar cells with basally located round nuclei and prominent nucleoli. In contrast, however, the columnar cells in most of the lesion contained abundant mucinous cytoplasm resembling Brunner’s glands as well as areas of prominent paneth cell differentiation. The characteristic amphophilic ground glass cytoplasm of PGAs was only noted in a minor component of the lesion. MUC6 and MUC5AC, immunostains that are typically expressed in PGA, were negative. Additionally, p53 showed a wild-type pattern, beta- catenin showed normal membranous staining, and the Ki-67 index was low.
Results
After review of the literature and expert consultation, we were not able to fully classify this lesion under any documented entity, however, we believe that it could be akin to PGA. Authors hypothesized that PGAs may originate from stem cells within Brunner glands as a response to chronic injury. These cells may then differentiate upwards, forming gastric foveolar metaplasia or downwards giving rise to Brunner gland hyperplasia.
Conclusion
Based on this hypothesis, the proliferating cells are prone to mutations resulting in a hyperplasia/metaplasia to dysplasia sequence that leads to the formation of PGAs or lesions such as the one demonstrated here.

Abstract
Objective: China adopted an unprecedented province-scale quarantine since January 23rd 2020, after the novel coronavirus (COVID-19) broke out in Wuhan in December 2019. Responding to the challenge of limited testing capacity, large-scale (>20 000 tests per day) standardized and fully-automated laboratory (Huo-Yan) was built as an ad-hoc measure. There is so far no empirical data or mathematical model to reveal the impact of the testing capacity improvement since quarantine. Methods: Based on the suspected case data released by the Health Commission of Hubei Province and the daily testing data of Huo-Yan Laboratory, the impact of detection capabilities on the realization of "clearing" and "clearing the day" of supected cases was simulated by establishing a novel non-linear and competitive compartments differential model. Results: Without the establishment of Huo-Yan, the suspected cases would increase by 47% to 33 700, the corresponding cost of quarantine would be doubled, the turning point of the increment of suspected cases and the achievement of "daily settlement" (all newly discovered suspected cases are diagnosed according to the nucleic acid testing result) would be delayed for a whole week and 11 days. If the Huo-Yan Laboratory could ran at its full capacity, the number of suspected cases could start to decrease at least a week earlier, the peak of suspected cases would be reduced by at least 44%, and the quarantine cost could be reduced by more than 72%. Ideally, if a daily testing capacity of 10 500 tests was achieved immediately after the Hubei lockdown, "daily settlement" for all suspected cases could be achieved. Conclusions: Large-scale, standardized clinical testing platform, with nucleic acid testing, high-throughput sequencing, and immunoprotein assessment capabilities, need to be implemented simultaneously in order to maximize the effect of quarantine and minimize the duration and cost of the quarantine. Such infrastructure, for both common times and emergencies, is of great significance for the early prevention and control of infectious diseases.

Abstract
Objective: To explore the clinical characteristics and establish a corresponding prognostic scoring model in patients with early-stage clinical features of hepatitis B-induced acute-on-chronic liver failure (HBV-ACLF). Methods: Clinical characteristics of 725 cases with hepatitis B-related acute-on-chronic hepatic dysfunction (HBV-ACHD) were retrospectively analyzed using Chinese group on the study of severe hepatitis B (COSSH). The independent risk factors associated with 90-day prognosis to establish a prognostic scoring model was analyzed by multivariate Cox regression, and was validated by 500 internal and 390 external HBV-ACHD patients. Results: Among 725 cases with HBV-ACHD, 76.8% were male, 96.8% had cirrhosis base,66.5% had complications of ascites, 4.1% had coagulation failure in respect to organ failure, and 9.2% had 90-day mortality rate. Multivariate Cox regression analysis showed that TBil, WBC and ALP were the best predictors of 90-day mortality rate in HBV-ACHD patients. The established scoring model was COSS-HACHADs = 0.75 × ln(WBC) + 0.57 × ln(TBil)-0.94 × ln(ALP) +10. The area under the receiver operating characteristic curve (AUROC) of subjects was significantly higher than MELD, MELD-Na, CTP and CLIF-C ADs(P < 0.05). An analysis of 500 and 390 cases of internal random selection group and external group had similar verified results. Conclusion: HBV-ACHD patients are a group of people with decompensated cirrhosis combined with small number of organ failure, and the 90-day mortality rate is 9.2%. COSSH-ACHDs have a higher predictive effect on HBV-ACHD patients' 90-day prognosis, and thus provide evidence-based medicine for early clinical diagnosis and treatment.

Abstract
Cognitive motor dissociation describes a subset of patients with disorders of consciousness who show neuroimaging evidence of consciousness but no detectable command-following behaviours. Although essential for family counselling, decision-making, and the design of rehabilitation programmes, the prognosis for patients with cognitive motor dissociation remains under-investigated. The current study included 78 patients with disorders of consciousness who showed no detectable command-following behaviours. These patients included 45 patients with unresponsive wakefulness syndrome and 33 patients in a minimally conscious state, as diagnosed using the Coma Recovery Scale-Revised. Each patient underwent an EEG-based brain-computer interface experiment, in which he or she was instructed to perform an item-selection task (i.e. select a photograph or a number from two candidates). Patients who achieved statistically significant brain-computer interface accuracies were identified as cognitive motor dissociation. Two evaluations using the Coma Recovery Scale-Revised, one before the experiment and the other 3 months later, were carried out to measure the patients’ behavioural improvements. Among the 78 patients with disorders of consciousness, our results showed that within the unresponsive wakefulness syndrome patient group, 15 of 18 patients with cognitive motor dissociation (83.33%) regained consciousness, while only five of the other 27 unresponsive wakefulness syndrome patients without significant brain-computer interface accuracies (18.52%) regained consciousness. Furthermore, within the minimally conscious state patient group, 14 of 16 patients with cognitive motor dissociation (87.5%) showed improvements in their Coma Recovery Scale-Revised scores, whereas only four of the other 17 minimally conscious state patients without significant brain-computer interface accuracies (23.53%) had improved Coma Recovery Scale-Revised scores. Our results suggest that patients with cognitive motor dissociation have a better outcome than other patients. Our findings extend current knowledge of the prognosis for patients with cognitive motor dissociation and have important implications for brain-computer interface-based clinical diagnosis and prognosis for patients with disorders of consciousness.
