ABSTRACT
Background: Thyroid hormones (THs) have been found that it is closely associated with the onset and progression of non-alcoholic fatty liver disease (NAFLD). However, the current study could not verify the intrinsic relationship between thyroid hormones and NAFLD, which requires further research. Methods: The searches of studies reported both TH level in serum and NAFLD were performed in PubMed, Web of Science, Cochrane Library, and Embase databases. We combined an overall meta-analysis with a dose-response meta-analysis to assess the correlation and dose-response relationship between thyroid function levels and the risk of NAFLD. Results: Overall, 10 studies were included with a total of 38,425 individuals. We found that the non-linear dose-response model showed that for every 1 ng/dL increase in FT4, the risk of NAFLD was reduced by 10.56% (p=0.003). The odds ratios (ORs) for NAFLD with high free triiodothyronine (FT3) exposure compared to those with low FT3 were 1.580 (95% CI 1.370 to 1.830, I2 = 0.0%, p<0.001) in the overall meta-analysis. The continuous variable meta-analysis indicated that individuals with high levels of TSH (SMD=1.32, 95% CI 0.660 to 1.970, p<0.001) had significantly higher levels of liver fibrosis than those with low levels. Conclusions: Our findings only validate that there is a correlation between the occurrence of NAFLD and abnormal levels of THs, and it is expected that more observational studies will still be conducted in the future to further demonstrate the relationship between thyroid hormones and NAFLD. Trial registration: Registered number in PROSPERO: CRD42023405052.

Objective:To investigate the relationship between intestinal flora and acute respiratory distress syndrome in patients with severe acute pancreatitis.Methods:One hundred and six patients with severe acute pancreatitis admitted to a hospital from March 2019 to February 2021 were selected as the observation group for prospective analysis. They were divided into concurrent group (52 cases) and non-concurrent group (54 cases) according to whether they were complicated with acute respiratory distress syndrome. In addition, 100 healthy people in the same period were selected as the control group to analyze the relationship between intestinal flora and acute respiratory distress syndrome in patients with severe acute pancreatitis.Results:There were significant differences in the number of intestinal flora ( Lactobacillus, Bifidobacterium, Escherichia coli) between the observation group and the control group ( t = 49.69, 73.28 and 46.32; P<0.05). There were significant differences in the number of intestinal flora ( Lactobacillus, Bifidobacterium, Escherichia coli) between the concurrent group and the non-concurrent group ( t = 34.85, 39.71 and 23.47; P<0.05). The levels of serum endotoxin, diamine oxidase and D-lactic acid in the concurrent group were significantly higher than those in the non-concurrent group: (0.63 ± 0.16) EU/ml vs. (0.45 ± 0.08) EU/ml, (6.29 ± 1.18) U/ml vs. (4.89 ± 0.91) U/ml, (11.63 ± 2.84) mmol/L vs. (9.33 ± 2.61) mmol/L ( t = 7.37, 6.85 and 4.34, P<0.05). Spearman analysis showed that severe acute pancreatitis complicated with acute respiratory distress syndrome was negatively correlated with the number of intestinal Lactobacillus and Bifidobacterium ( r = - 0.342 and - 0.291, P = 0.011 and 0.021), which was positively correlated with the number of intestinal Escherichia coli flora ( r = 0.263, P = 0.033). Conclusions:Intestinal colony imbalance is common in patients with severe acute pancreatitis, and the imbalance of intestinal colony and the impairment of intestinal mucosal barrier function are more serious in patients with acute respiratory distress syndrome. There is a significant correlation between severe acute pancreatitis complicated with acute respiratory distress syndrome and its intestinal colony.
ABSTRACT
OBJECTIVE@#To investigate the involvement of endothelial cells (ECs)-derived exosomes in the anti-apoptotic effect of Danhong Injection (DHI) and the mechanism of DHI-induced exosomal protection against postinfarction myocardial apoptosis.@*METHODS@#A mouse permanent myocardial infarction (MI) model was established, followed by a 14-day daily treatment with DHI, DHI plus GW4869 (an exosomal inhibitor), or saline. Phosphate-buffered saline (PBS)-induced ECs-derived exosomes were isolated, analyzed by miRNA microarray and validated by droplet digital polymerase chain reaction (ddPCR). The exosomes induced by DHI (DHI-exo), PBS (PBS-exo), or DHI+GW4869 (GW-exo) were isolated and injected into the peri-infarct zone following MI. The protective effects of DHI and DHI-exo on MI hearts were measured by echocardiography, Masson's trichrome staining, and TUNEL apoptosis assay. The Western blotting and quantitative reverse transcription PCR (qRT-PCR) were used to evaluate the expression levels of miR-125b/p53-mediated pathway components, including miR-125b, p53, Bak, Bax, and caspase-3 activities.@*RESULTS@#DHI significantly improved cardiac function and reduced infarct size in MI mice (P<0.01), which was abolished by the GW4869 intervention. DHI promoted the exosomal secretion in ECs (P<0.01). According to the results of exosomal miRNA microarray assay, 30 differentially expressed miRNAs in the DHI-exo were identified (28 up-regulated miRNAs and 2 down-regulated miRNAs). Among them, DHI significantly elevated miR-125b level in DHI-exo and DHI-treated ECs, a recognized apoptotic inhibitor impeding p53 signaling (P<0.05). Remarkably, treatment with DHI and DHI-exo attenuated apoptosis, elevated miR-125b expression level, inhibited capsase-3 activity, and down-regulated the expression levels of proapoptotic effectors (p53, Bak, and Bax) in post-MI hearts, whereas these effects were blocked by GW4869 (P<0.05 or P<0.01).@*CONCLUSION@#DHI and DHI-induced exosomes inhibited apoptosis, promoted the miR-125b expression level, and regulated the p53 apoptotic pathway in post-infarction myocardium.

Objective:At present,the doctor-patient relationship is tense.The prevalence of negative emotions,such as depression and anxiety,among healthcare workers is increasing every year.Negative attitudes of medical workers toward mental problems may aggravate the doctor-patient conflict and psychological problems of medical workers.This study aims to explore the complex network relationships between outpatient medical workers'attitudes toward mental problems,doctor-patient relationships,and their depression/anxiety levels. Methods:A total of 578 outpatient medical staff from the Second Xiangya Hospital of Central South University(167 males,411 females)completed questionnaires on their attitudes toward mental problems,doctor-patient relationships,and depression/anxiety symptoms.Network analysis was conducted separately to construct the"attitude towards mental problems-doctor-patient relationship network"and"depression-anxiety related network". Results:The edge between"M15(insulting words)"and"D8(waste time)"showed the strongest strength in the"attitude towards mental problems-doctor-patient relationship network",and"M15(insulting words)"had the highest bridge strength in the network.For the analysis of emotional variables,"P1(anhedonia)"showed the most obvious association with"D10(communication difficulties)"in the doctor-patient relationship and"M2(poor quality of life)"in the psychiatric attitudes,and"P1(anhedonia)"was the key bridge symptom in the network. Conclusion:The"insulting words"may be an intervention target for medical workers'attitudes toward mental problems.The"anhedonia"in depression is the potential symptom that needs to be treated.Intervention targeting these variables may be beneficial to improve the mental health level of medical workers and the doctor-patient relationship.

OBJECTIVE@#To explore the application of extended reality (XR) technology in clinical surgeries for improving the success rate of surgeries.@*METHODS@#To assist the surgeons to better understand the location, size and geometric shape of the lesions and reduce potential radiation exposure in minimally invasive surgical navigation based on two-dimensional images, we constructed three-dimensional models based on CT data and used XR technology to achieve intraoperative navigation. An improved quaternion method was used to improve the accuracy of electromagnetic positioning, with which the system error of positioning accuracy was reduced to below 2 mm. A 5G network was used to optimize the server GPU programming algorithm, and real-time video stream coding strategy and network design were adopted to reduce data transmission jam and delay in the remote surgery network, which achieved an average delay of less than 60 ms. A Gaussian distribution deformation model was used to simulate collision detection and stress deformation of the tissues to achieve a tactile perception effect.@*RESULTS AND CONCLUSION@#The intraoperative navigation system based on XR technology allowed more accurate determination of the location of the lesions, effectively reduced the surgical risk, and avoided the risk of intraoperative radiation exposure. The low latency and high fidelity of 5G network achieved real-time interaction during the surgery to provide a technical basis for multi-terminal remote cooperative surgery. The combination of force feedback technology and XR technology enables the surgeons to conduct deep immersion preoperative planning and virtual surgery to improve the success rate of surgery and shorten the learning curve.

To assess the variations of soil quality among land use types and with altitude in the rocky mountain area of northern Hebei Province is critical for preventing further human-induced degradation of land and vegetation, and for formulating a strategic plan on vegetation restoration after the Beijing Winter Olympics. Taking Betula platyphylla natural forest, Larix gmelinii plantation, natural grassland and abandoned cropland as research objects, 13 soil physicochemical indices (e.g., soil bulk density, porosity and soil nutrient content) were measured to compare soil quality among land use types. The results showed that soil quality presented the trend as B. platyphylla natural forest > natural grassland > L. gmelinii plantation > abandoned cropland. B. platyphylla natural forest had the best soil quality due to high total nitrogen (3.24 ±1.42 g·kg-1) and phosphorus (0.59±0.10 g·kg-1) contents, suggesting that long-term soil nutrient accumulation played an important role in preventing soil degradation. Soil quality in natural grassland was lower than that in B. platyphylla natural forest, due to topographic factors and coarse soil fraction. Soil physical properties in L. gmelinii plantation had been substantially improved after 40 years restoration, as indicated by significant reductions in soil gravel fraction, while soil nutrient contents changed little. The low soil quality in abandoned cropland was attributable to low vegetation coverage and intense human activities in the low-altitude area. Driven by soil total nitrogen, soil quality under the four land use types increased with altitude, and peaked at about 1700 m. We suggested that enclosure and ecological restoration measures should be strengthened in ecologically-fragile, low-altitude areas, taking sustainable development into consideration for high-density stands and promoting plantations to adapt to environmental change.

Plant invasion is one of the most serious global problems, destroying ecosystem structure and function. With the severity of plant invasion, it is particularly important to understand the mechanisms of plant invasion in order to control and solve the problem. We summarized different mechanisms of plant invasion and the synergy among them, expounded the allelopathy, the plant-soil feedbacks, the reciprocal symbiosis, the effects of plant functional traits and phenotype plasticity in the process of plant invasion, and comprehensively analyzed the synergy of multiple mechanisms on plant invasion trajectory. According to the results, the invasion trajectory of alien plants in the invasive site was divided into four stages: introduction, colonization, establishment, and invasion. Integrating all kinds of obstacles and promoting factors encountered into it and putting forward the invasion curve of plants would contribute to the future research and management of invasive plants. We further highlighted the current research deficiencies and future research directions and objectives based on analyzing current research methods of plant invasion.

INTRODUCTION: Spinal ganglioneuroma (GN) is the most benign neoplasm of neuroblastic origin. There is little knowledge about spinal GN because of sporadic cases reported. The objective of this study is to describe the clinical manifestations and long-term follow-up outcomes of spinal GN after consecutive treatment. METHODS: The clinical and follow-up data of 31 patients with spinal GN receiving consecutive treatment in our institute are retrospectively analyzed. RESULTS: The mean age of the 31 patients was 40.39 ± 14.8 years. They were diagnosed with spinal GN and received surgical treatment in our institution between February 2012 and August 2019. Of them, 22 (71%) patients presented preoperative neurological symptoms. The mean duration from symptom onset to surgery was 19.76 ± 49.59 months. Eighteen patients received complete surgical resection and 13 patients received subtotal excision. In addition, radicotomy was performed simultaneously after sophisticated consideration in 19 patients. The follow-up period averaged 64.13 ± 22.67 months. The preoperative neurological dysfunction was improved significantly during the follow-up period in all cases. No local recurrence or malignant transformation has occurred so far. CONCLUSION: Spinal GN is a rare but benign neoplasm, and the origin of spinal GN remains controversial. With our experience, we propose that the origin of spinal GN from dorsal root ganglion should be equally considered as its counterpart of sympathetic ganglion. Complete resection is the preferred surgical strategy to avoid malignant events and recurrence. And the close postoperative follow-up observations are warranted.

Objective:To explore the behavior and influencing factors of mobile health (m-Health) information searching among patients with cancer, aiming to provide evidence for the provision of medical health information.Methods:A cross-sectional survey was conducted.A total of 535 patients with cancer were recruited from a cancer hospital in Zhejiang Province from September to December 2017.Measurement tools included the demographic information questionnaire, mobile health information search behavior questionnaire, mobile health information search environment questionnaire, cancer needs questionnaires-short form and ehealth literacy scale.SPSS 26.0 was used for descriptive statistical analysis, one-way analysis of variance, Pearson correlation analysis and multiple linear regression analysis.Results:The total score of mobile health information search behavior of cancer patients was (60.84±9.60), and 66.5% of participants reported that they "never" or "occasionally" searched health information via mobile.The total score of information needs was (80.99±27.86), electronic health literacy was (26.54±7.85), mobile health information search environment was (8.00±2.86). m-Health information search behavior was positively correlated with information needs ( r=0.251, P<0.01), ehealth literacy ( r=0.538, P<0.01), and m-Health information search environment ( r=0.267, P<0.01). The stepwise regression analysis revealed that the place of residence, working status, income level, ehealth literacy, mobile health information search environment and information needs were statistically significant associated with the m-Health information searching behavior among cancer patients, which accounted for 39.3% of the total variance ( F=12.151, P<0.01). Compared with patients living in the central cities, those living in the small and medium-sized cities( β=0.092, P=0.031) had higher score in m-Health information behavior.Compared with patients working on normal schedule, those took sick days ( β=0.156, P=0.017) and working fewer hours ( β=0.138, P=0.002) had higher score m-Health information behavior.Compared with patients with monthly income of 1 000-3 000 yuan ( β=-0.194, P=0.002), those with monthly income less than 1 000 yuan had higher score in m-Health information behavior.The ehealth literacy ( β=0.425, P=0.000), mobile health information search environment ( β=0.179, P=0.000) and information needs ( β=0.091, P=0.027) were positive influencing factors of m-Health information search behavior. Conclusion:Patients with cancer did not report high m-Health information search behavior.Place of residence, working status, income level, ehealth literacy, m-Health information search environment and information demand were the influencing factors of m-Health information search behavior among patients with cancer.

ABSTRACT
The emergence of coronavirus disease 2019 (COVID-19) pandemic led to an urgent need to develop therapeutic interventions. Among them, neutralizing antibodies play crucial roles for preventing viral infections and contribute to resolution of infection. Here, we describe the generation of antibody libraries from 17 different COVID-19 recovered patients and screening of neutralizing antibodies to SARS-CoV-2. After 3 rounds of panning, 456 positive phage clones were obtained with high affinity to RBD (receptor binding domain). Then the positive clones were sequenced and reconstituted into whole human IgG for epitope binning assays. After that, all 19 IgG were classified into 6 different epitope groups or Bins. Although all these antibodies were shown to have ability to bind RBD, the antibodies in Bin2 have more superiority to inhibit the interaction between spike protein and angiotensin converting enzyme 2 receptor (ACE2). Most importantly, the antibodies from Bin2 can also strongly bind with mutant RBDs (W463R, R408I, N354D, V367F and N354D/D364Y) derived from SARS-CoV-2 strain with increased infectivity, suggesting the great potential of these antibodies in preventing infection of SARS-CoV-2 and its mutations. Furthermore, these neutralizing antibodies strongly restrict the binding of RBD to hACE2 overexpressed 293T cells. Consistently, these antibodies effectively neutralized pseudovirus entry into hACE2 overexpressed 293T cells. In Vero-E6 cells, these antibodies can even block the entry of live SARS-CoV-2 into cells at only 12.5 nM. These results suggest that these neutralizing human antibodies from the patient-derived antibody libraries have the potential to become therapeutic agents against SARS-CoV-2 and its mutants in this global pandemic.
ABSTRACT
BackgroundEffective antiviral drugs for COVID-19 are still lacking. This study aims to evaluate the clinical outcomes and plasma concentrations of baloxavir marboxil and favipiravir in COVID-19 patients. MethodsFavipiravir and baloxavir acid were evaluated for their antiviral activity against SARS-CoV-2 in vitro before the trial initiation. We conducted an exploratory trial with 3 arms involving hospitalized adult patients with COVID-19. Patients were randomized assigned in a 1:1:1 ratio into baloxavir marboxil group, favipiravir group, and control group. The primary outcome was the percentage of subjects with viral negative by Day 14 and the time from randomization to clinical improvement. Virus load reduction, blood drug concentration and clinical presentation were also observed. The trial was registered with Chinese Clinical Trial Registry (ChiCTR 2000029544). ResultsBaloxavir showed antiviral activity in vitro with the half-maximal effective concentration (EC50) of 5.48 {micro}M comparable to arbidol and lopinavir, but favipiravir didnt demonstrate significant antiviral activity up to 100 {micro}M. Thirty patients were enrolled. The percentage of patients who turned viral negative after 14-day treatment was 70%, 77%, and 100% in the baloxavir, favipiravir, and control group respectively, with the medians of time from randomization to clinical improvement was 14, 14 and 15 days, respectively. One reason for the lack of virological effect and clinical benefits may be due to insufficient concentrations of these drugs relative to their antiviral activities. ConclusionsOur findings do not support that adding either baloxavir or favipiravir under the trial dosages to the existing standard treatment.
ABSTRACT
Stenting for iliac vein stenosis or compression has become a common therapeutic approach in recent years. The antithrombotic therapy after the stent deployment, however, reaches no consensus. Medications strategies and patients' prognoses differ in non-thrombotic, acute thrombotic and chronic thrombotic these three circumstances. Non-thrombotic patients usually possess satisfactory stent patency whatever antithrombotic therapy is used. Anticoagulant is the basic medication for acute thrombotic patients, benefits from additional antiplatelet drug remains to be clarified. In terms of chronic thrombotic patients, their prognoses are unsatisfactory under all antithrombotic therapies. In this review, we outlined the recent progress of antithrombotic therapy after iliac vein stenting, aiming to provide feasible medication plans for each circumstance.

Stellera chamaejasme L. is a traditional Chinese medicine with a long history to treat stubborn skin ulcer, and it also has antiviral and antitumor effects. Neochamaejasmine B (NCB), Neochamaejasmine A (NCA) and Chamaechromone (CMC) are the major components in dried roots of Stellera chamaejasme L.. Our studies suggested that NCB, NCA and CMC are inhibitors of Organic anion transporter 1 (OAT1). OAT1 is encoded by solute carrier family 22 member 6 gene (SLC22A6) in humans and plays a critical role in the organic anion drug uptake and excretion in the kidney. Lamivudine is the typical substrate of OAT1 and is frequently used in combination with other antiviral drugs in clinical antiviral treatments. The aim of this study is to investigate the interaction and its mechanism between these bi-flavone components in Stellera chamaejasme L. and lamivudine via OAT1 both in vitro and in vivo. In vitro, the uptake studies in Madin-Darby canine kidney (MDCK) cells overexpressing OAT1 suggested that NCB inhibited the uptake of 6-CFL and lamivudine.Similar results were obtained for NCA and CMC. NCB was a noncompetitive and competitive inhibitor interaction with OAT1. IC values of NCB, NCA and CMC for inhibiting OAT1-mediated lamivudine transport were 2.46, 8.35 and 0.61 μmol·L, respectively. In vivo, the pharmacokinetic results of lamivudine in rats showed that the mean area under the plasma concentration-time curve (AUC) and maximal plasma concentration (C) of lamivudine after co-administration is increased 2.94-fold and 1.87-fold, respectively, compared to lamivudine administration alone. The results of interactions between lamivudine and these bi-flavone components in Stellera chamaejasme L. extracts via OAT1 in vivo are consistent with studies in vitro. The inhibition of OAT1-mediated uptake of lamivudine by NCB, NCA and CMC is the possible mechanism for Stellera chamaejasme L. extracts improving the oral bioavailability of lamivudine in rats.
ABSTRACT
Objective To investigate the effect of dexmedetomidine on early postoperative cognitive func-tion in elderly patients undergoing liver resection. Method Fifty-four ASAⅡ~Ⅲelderly patients scheduled for liver resection were divided into 3 groups(18 in each group):the control group(group C),group D1 and group D2. The levels of serum 8-iso-PGF2α,IL-6,TNF-α and S100β protein were measured,and Da-jvO2,CjvO2and CERO2were calculated at the time before operation and at the end of operation,respectively.Incidence of postoper-ative cognitive dysfunction(POCD)were recorded within seven days after operation. Results Compared with the time before operation,levels of serum 8-iso-PGF2α,IL-6,TNF-α,S100β protein and Da-jvO2,CERO2of patients in 3 groups significantly increased at the end of operation(P < 0.05,respectively). The levels of serum 8-iso-PGF2α,IL-6,TNF-α,S100β protein and Da-jvO2,CERO2of patients decreased in group D1 and D2 than those in group C at the end of operation(P<0.05).Incidence of POCD in group D1 and D2 was lower than that of group C (P<0.05).Conclusion Dexmedetomidine can decrease the incidence of POCD for the elderly patients undergo-ing liver resection,the potential mechanism is that dexmedetomidine can reduce oxidative stress response,inhibit inflammatory response in patients and improve the cerebral oxygen metabolism during the operation.
ABSTRACT
Differences of the individual toxic effects of antitumor drugs have been a concern in clinical treatment of cancers. The drug toxicity was not only related to the age, sex, and drug interactions, but also to the expression of protein involved in the metabolism, targets and transporters of drugs. Drug transporter mediates the absorption, distribution and elimination of some drugs, which exhibits a great significance in pharmacology and clinical practice. The purpose of this review is to provide information regarding trans-porter-medicated toxic effects of antitumor drugs in order to reduce or avoid the transporter-medicated toxic effects, and to promote reasonable drug use and individualized application of antitumor drugs in clinics.

ABSTRACT
Objective To study the effect of cholecalciterol cholesterol emulsion(CCE)in the zymosan(Z)-induced acute hepatic injury. Meth-ods A total of 36 C57 BL/6 mice were randomly divided into 4 groups,namely negative control(CON)group,CCE group,Z group and CCE+Z group,respectively. There were 9 mice in each group. Mice from CON group and Z group were fed with pure water. Mice from CCE group and CCE+Z group were fed with cholecalciterol cholesterol emulsion 20μL dissolved in 200 mL pure water which was kept in darkness. After 14 days, Z group and CCE+Z group were injected with zymosan at a dose of 500 mg/kg. After 18 hours,all the mice in each group were sacrificed. The liver tissues were harvested for histopathological examination. The serum ALT levels were determined. The molecular expression of IL-6 and IL-18 in liv-er tissue of mice were evaluated by Western blotting and real-time quantitative PCR method. Results The results of histopathological examination showed that liver tissue damage in CCE+Z group was lighter than that of Z group ,and heavier than that of the CON group. Compared to the CON group,Z group had the highest serum ALT level,followed by CCE+Z group,while in Z group was significantly lower than that in CON group(all P<0.05). The expression of IL-6 and IL-18 protein and mRNA showed level of Z group was apparently higher than those of CON group and CCE+Z group(all P<0.05). Conclusion Cholecalciterol cholesterol emulsion can play certain protective effect on zymosan-induced liver injury in mice.
