Abstract
Objective: To observe the clinical effect of free posterior interosseous artery perforator flap carrying superficial vein for reconstructing severe perioral scar hyperplasia and contracture. Methods: The retrospective observational study method was used. From August 2019 to March 2023, 11 patients with severe perioral scar hyperplasia and contracture after severe facial burns who met the inclusion criteria were admitted to General Hospital of TISCO (the Sixth Hospital of Shanxi Medical University). All patients were male and aged 23 to 56 years, with an average age of 31.3 years. After the perioral scar was removed and released, the wound area was 3.0 cm×2.0 cm to 10.5 cm×2.0 cm. The free posterior interosseous artery perforator flap carrying superficial vein was used to repair the wound, and the flap incision area was 3.5 cm×2.5 cm to 11.0 cm×2.5 cm. Among them, 6 patients required repair of wounds after resecting scar around ipsilateral upper and lower lips, and the lobular treatment of the flap was conducted. The wound in the flap donor area was directly sutured. After surgery, the survival of the flap and the occurrence of vascular crisis were observed. During follow-up after surgery, the appearance, texture, and color of the flap, the appearance of the flap donor area, and improvements of crooked mouth, drooling, limited mouth opening, and lip valgus in patients were observed. Results: All the flaps in patients completely survived after surgery, with no occurrence of vascular crisis. During follow-up of 6 to 36 months after surgery, the flap was not significantly bloated, was soft in texture, and had a similar color to that of the normal facial skin. Only linear scars were left in the flap donor area, and crooked mouth, drooling, limited mouth opening, and lip valgus in patients were significantly improved. Conclusions: The free posterior interosseous artery perforator flap carrying superficial vein can reconstruct severe perioral scar hyperplasia and contracture, with low incidence of postoperative flap vascular crisis, and the lobular treatment of flaps can repair wounds around unilateral upper and lower lips at the same time. After surgery, the appearance and function of the perioral area are significantly improved. The flap is a good choice for repairing small area of severe perioral scar hyperplasia and contracture.

Abstract
We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Abstract
BACKGROUND Most of hepatocellular carcinoma (HCC) arises on the background of chronic inflammation. The presence of infiltrating inflammatory cells is associated with tumour initiation, progression and clinical response to treatment. The influence of white blood cell (WBC) subtype counts on HCC progression remains unclear. METHODS In this study, we performed a Mendelian randomization (MR) study with the validation of two datasets. The summary data for WBC counts were extracted from a recent large GWAS of individuals of European ancestry. The GWAS data related to HCC were obtained from the UK Biobank (UKB). Univariable and multivariable MR analyses were used to identify risk factors genetically associated with HCC risks. RESULTS In the discovery dataset, multivariable MR analysis revealed that sum basophil neutrophil counts had an independent causal effect on the occurrence of HCC, with the sum basophil neutrophil counts as follows: (OR = 0.437, P = 0.003, CI 0.252-0.757). Similarly, in the validation dataset, total basophil neutrophil counts were also been identified as an independent risk factor for HCC. The sum basophil neutrophil counts were as follows: (OR = 0.574, P = 0.021, CI 0.358-0.920). CONCLUSION In the European population, genetically predicted lower total basophil neutrophil counts might be an independent risk factor for HCC.

Abstract
Background Exosomes derived from cancer cells encapsulate various kinds of tumor-specific molecules and thus can interact with adjacent or distant cells to mediate information exchange. Long non-coding RNAs (lncRNAs) in exosomes have the potential as diagnostic and prognostic biomarkers in different types of cancers. The current study was aimed to identify circulating exosomal lncRNAs for the diagnosis of colorectal cancer (CRC). Methods Exosomes were isolated from the serum by ultracentrifugation and verified by transmission electron microscope (TEM), qNano, and immunoblotting. Exosomal lncRNAs FOXD2-AS1, NRIR, and XLOC_009459 were selected by lncRNA microarray and validated by qPCR in 203 CRC patients and 201 healthy donors. The receiver operating characteristic curve (ROC) was used to assess the diagnostic efficiency of serum exosomal lncRNAs. Results Exosomal FOXD2-AS1, NRIR, and XLOC_009459 (TCONS_00020073) levels were significantly upregulated in 203 CRC patients and 80 early-stage CRC patients compared to 201 healthy donors, possessing the area under the curve (AUC) of 0.728, 0.660, and 0.682 for CRC, as well as 0.743, 0.660, and 0.689 for early-stage CRC, respectively. Notably, their combination demonstrated the markedly elevated AUC of 0.736 for CRC and 0.758 for early-stage CRC, indicating their potential as diagnostic biomarkers for CRC. Conclusions Our data suggested that exosomal lncRNAs FOXD2-AS1, NRIR, and XLOC_009459 act as the promising biomarkers for the diagnostics of CRC and early-stage CRC.

Abstract
Toxoplasma gondii is a world-widely spread zoonotic parasite. However, scarce knowledge is known about the prevalence of T. gondii infection in people in Hubei province, China. This study herein was to perform epidemiological investigation of T. gondii infection in people in this region. A total 12527 blood samples were obtained during 2015-2018, and were assayed for T. gondii antibodies of IgG and IgM, respectively by employing an indirect hemagglutination test (IHA). The results discovered that the prevalence of T. gondii in people was 2.44% and 6.1%, respectively based on antibodies of IgG and IgM, respectively. The prevalence was ranged from 0.3% to 5.4% during 2015-2018 based on IgM antibodies. For genders, the prevalence was 0.7% and 2.6% in males and females, respectively based on IgM antibodies. In different years, the prevalence was ranged from 4.9% to 14.0% based on IgG antibodies. The prevalence of T. gondii was 4.9% and 6.6% in males and femalesy based on IgG antibodies. The current results may be helpful for the implementation of preventive measures against Toxoplasma infection among people living in this region.

Abstract
Objective:To study the effects of postauricular injection of methylprednisolone on medium-high frequency sudden hearing loss.Method:The data of 45 patients with invalid treatment who were diagnosed as medium-high frequency sudden hearing loss were retrospectively studied. They were divided into postauricular injection group and non-postauricular injection group. The treatment efficiency and hearing improvement at each frequency were compared between the two groups.Result:The improvements of hearing threshold in the non-postauricular injection group were(6.30±5.00)dB HL,(3.80±5.52)dB HL,(5.35±5.50)dB HL,(15.60±11.84)dB HL,(19.60±13.46)dB HL,(15.40±12.90)dB HL at 250, 500, 1000, 2000, 4000 and 8000Hz, respectively. The hearing improvements of the postauricular injection group were (5.35±6.22)dB HL,(2.50±3.00)dB HL,(4.65±6.60)dB HL,(23.75±10.75)dB HL,(25.75±11.73)dB HL,(30.50±14.50)dB HL at 250, 500,1000,2000,4000 and 8000Hz, respectively. There were significant differences between the two groups in hearing improvements at 2000-8000Hz. The treatment effective rates were 44% and 80% for the non-postauricular injection group and postauricular injection group respectively, which showed a significant difference(χ²=8.385P<0.05).Conclusion:Postauricular injection of methylprednisolone as a remedy treatment is safe and effective for sudden hearing loss in middle and high frequency.

Abstract
Objective:To investigate the expression of RhoA, Ezrin and CD44 proteins in laryngeal squamous cell carcinoma (LSCC), and analyze their roles and mutual relations in invasion and metastasis.Method:The expressions of RhoA, Ezrin and CD44 in 68 specimens of LSCC and 35 specimens of normal laryngeal mucosa tissues were detected by immunohistochemical SABC staining. The results were correlated with clinicopathological parameters.Result:The positive expression rates of RhoA, Ezrin and CD44 in LSCC were 80.9%,82,4% and 70.6%, and the positive expression rates of RhoA, Ezrin and CD44 in normal laryngeal mucosa tissues were 28.5%, 25.7% and 20%, respectively. The expressions of RhoA, Ezrin and CD44 were significantly correlated to depth of invasion (T), lymph node metastasis (N), clinical TNM stage, tumor grade respectively (P< 0.05), but not to age, gender, smoking, tumor location (P> 0.05). The expression of RhoA was positively correlated to that of Ezrin in LSCC, and the expression of Ezrin was positively correlated to that of CD44 in LSCC too (P< 0.05).Conclusion:Our findings suggested that high expressions of RhoA, Ezrin and CD44 might play an important role in the malignant progression of invasion and metastasis of LSCC, which indicated that they might have played synergistic effects in the process.

Abstract
Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound, the examiner and interpreter of the image are critical care medicine physicians. The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes. With the idea of critical care medicine as the soul, it can integrate the above information and clinical information, bedside real-time diagnosis and titration treatment, and evaluate the therapeutic effect so as to improve the outcome. CUS is a traditional technique which is applied as a new application method. The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept, implementation and application of CUS. It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure. At the same time, the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications, and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS. Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group, based on the rich experience of clinical practice in critical care and research, combined with the essence of CUS, to learn the traditional ultrasonic essence, established the clinical application technical specifications of CUS, including in five parts: basic view and relevant indicators to obtain in CUS; basic norms for viscera organ assessment and special assessment; standardized processes and systematic inspection programs; examples of CUS applications; CUS training and the application of qualification certification. The establishment of applied technology standard is helpful for standardized training and clinical correct implementation. It is helpful for clinical evaluation and correct guidance treatment, and is also helpful for quality control and continuous improvement of CUS application.

Abstract
Parkinson's disease (PD) is one of the most common neurodegenerative diseases and mainly manifests with decreasing numbers of dopaminergic neurons. Rapid eye movement (REM) sleep behavior disorder (RBD) has an incidence of 15-47% in all PD patients. Prion proteins (PrPs), which are expressed in both neurons and glial cells of the brain, are believed to be correlated with abnormal neurological functions, although their role in PD-related sleeping disorders remains unclear. We therefore investigated the expressional profiles of PrP in PD patients with RBD. Quantitative real-time polymerase chain reaction and western blotting were used to detect the mRNA and protein levels of PrP, respectively, in the cerebrospinal fluid (CSF) of PD patients with RBD, PD patients without sleeping disorder, and healthy people (N = 23 each). We investigated the correlation between the CSF PrP level and sleeping behavior in PD patients. Patients with PD complicated with RBD had significantly elevated CSF PrP expression levels (both mRNA and protein) compared with either PD patients without sleeping disorder or healthy individuals (P < 0.05 in both cases). There is elevated expression of PrP in the CSF of PD patients with RBD. This may benefit the diagnosis of PD-related RBD.

Abstract
As a ubiquitous reaction, glucosylation controls the bioactivity of cytokinins in plant growth and development. Here we show that genetic manipulation of zeatin-O-glucosylation regulates the formation of important agronomic traits in rice by manipulating the expression of OscZOG1 gene, encoding a putative zeatin O-glucosyltransferase. We found that OscZOG1 was preferentially expressed in shoot and root meristematic tissues and nascent organs. The growth of lateral roots was stimulated in the overexpression lines, but inhibited in RNA interference lines. In shoots, knockdown of OscZOG1 expression by RNA interference significantly improved tillering, panicle branching, grain number per panicle and seed size, which are important agronomic traits for grain yield. In contrast, constitutive expression of OscZOG1 leads to negative effects on the formation of the grain-yielding traits with a marked increase in the accumulation levels of cis-zeatin O-glucoside (cZOG) in the transgenic rice plants. In this study, our findings demonstrate the feasibility of improving the critical yield-determinant agronomic traits, including tiller number, panicle branches, total grain number per panicle and grain weight by downregulating the expression level of OscZOG1. Our results suggest that modulating the levels of cytokinin glucosylation can function as a fine-tuning switch in regulating the formation of agronomic traits in rice.

Abstract
Objective:Since nasopharyngeal carcinoma is easy to develop resistance during cisplatin-based chemotherapy,CXCR4 expression levels were elevated in mang tumors,and the factor to do with tumor metastasis and chemotherapy drug resistance,and so on has a very important link.We established cisplatin-resistant nasopharyngeal carcinoma cell line, named as CNE2/DDP, and investigated the function of CXCR4 in molecular mechanism behind this resistance.Method:CNE2/DDP was firstly build up by increasing concentration of cisplatin. And then afterwards,MTT assay, RNA interference techniques, microRNA overexpresion techniques, quantative PCR and western blotting were applied to analyze the function of CXCR4 and its downstream effectors.Result:①the expression of CXCR4 was increased in CNE2/DDP and downregulation of CXCR4 with CXCR4 siRNA was able to decrease the resistance of CNE/DDP to cisplatin; ②the expression of let-7a was decrease in CNE2/DDP, while the expression of bcl-2 was increased. Upregulation of let-7a via transfection of let-7a mimics could downregulate the expression of bcl-2 and damage the resistance of CNE2/DDP to cisplation;③downregulation of CXCR4 through CXCR4 siRNA transfection was capable of improving the expression of let-7a. Conclusion:We were the first to found that CXCR4 was related to chemoresistance of CNE2/DPP to cisplatin. Meanwhile, we confirmed that CXCR4 affected the expression of bcl-2 through regulating the expression of let-7a to modulate the chemoresistance of CNE2/DPP to cisplatin.

Abstract
Objective:To investigate the role of oxidative stress in smoking-related laryngeal squamous carcinoma through detecting the expression of antioxidant enzymes in smoking patients. Method:A total of 138 cases with laryngeal squamous cell carcinoma enrolled in the first hospital affiliated the northern he bei college from 2012 to 2015 and forty five volunteers were conducted. All participants were divided into three groups according to smoking index: group A(heavy smoking, 88 cases of laryngeal cancer patients) and group B(no smoking 50 cases of laryngeal cancer patients) and C group(45 heavy smoking volunteers).Catalase(CAT), glutathione peroxidase(GSH-px) and malondialdehyde(MDA) and the expression of NRF2 in serum, tissue adjacent to carcinoma, and carcinoma tissues from each groups were measured, respectively. Result:①the expression of the CAT and GSH-px in group A were significantly lower than that of group B(P <0.05), but higher than that of group C(P <0.05); ②the MDA level of group A is significantly higher than group B(P <0.05) and C group(P <0.01);③NRF2 was highly expressed in carcinoma tissues, and the expression level was negatively correlated with degree of carcinoma differentiation (P <0.05). Conclusion:Compared with nonsmoking patients, heavy smoking patients with laryngeal cancer were under more severe oxidative stress. NRF2 expression level in patients with laryngeal squamous cell carcinomas was associated with pathological stage.

Abstract
Time-domain electromagnetic system can implement great depth detection. As for the electromagnetic system, the receiver utilized an air coil sensor, and the matching mode of the sensor employed the resistance matching method. By using the resistance matching method, the vibration of the coil in the time domain can be effectively controlled. However, the noise of the sensor, especially the noise at the resonance frequency, will be increased as well. In this paper, a novel design of a low noise induction coil sensor is proposed, and the experimental data and noise characteristics are provided. The sensor is designed based on the principle that the amplified voltage will be converted to current under the influence of the feedback resistance of the coil. The feedback loop around the induction coil exerts a magnetic field and sends the negative feedback signal to the sensor. The paper analyses the influence of the closed magnetic feedback loop on both the bandwidth and the noise of the sensor. The signal-to-noise ratio is improved dramatically.

Abstract
Astrocytes provide structural, metabolic and trophic supports for neurons. However, there are no direct evidences whether astrocytes involve in the regulation of synaptic proteins expression and tau phosphorylation until now. Here, we injected 1 nmol fluorocitrate (FC), which preferentially taken up by astrocytes and results in reversible inhibition of the astrocytic tricarboxylic acid cycle, into the left lateral ventricle of the brain in the SD rats for 1h, and found that FC treatment decreased several memory-related proteins levels, such as AMPA receptor GluR1/2, postsynaptic density protein 93/95, Arc and phosphorylated cAMP response element binding proteins, while increased synaptophysin and synapsin I levels in the hippocampus. FC treatment also increased the levels of phosphorylated tau at multiple Alzheimer-related phosphorylation sites, as well as activation of glycogen synthase kinase-3β and inactivation of protein phosphatase-2A. Similar effects were also observed in the primary hippocampal neurons, which were cultured with the conditioned media from FC-treatment primary astrocytes. Our data suggest that astrocytes regulate neuronal tau phosphorylation and several synaptic proteins expression.

Abstract
Dendritic myxofibrolipoma is a newly described benign soft tissue tumor that could be easily mistaken for sarcoma. It develops primarily in the subcutis or muscular fascia of the head and neck, shoulders, etc. Histologically, the tumor is characterized by an admixture of mature adipose tissue, spindle and stellate cells, and abundant myxoid stroma with prominent collagenization. These neoplasms typically show positive immunoreactivity for CD-34, vimentin and Bcl-2. Herein, we described a rare case presenting with a papule on the nasal tip in a 69-year old patient. Histopathology and immunohistochemical staining confirmed the diagnosis. In short, it brings the attention of clinicians to the importance of proper identification and characterization of this tumor.
