Association between red cell distribution width-to-platelet ratio and short-term and long-term mortality risk in patients with acute ischemic stroke.

BACKGROUND: The objective of this study was to evaluate the association between red cell distribution width/platelet ratio (RPR) and 30-day and 1-year mortality in acute ischemic stroke (AIS). METHODS: Data for the retrospective cohort study were collected from the Medical Information Mart for Intensive Care (MIMIC) III database. RPR was divided into two groups: RPR ≤ 0.11 and RPR > 0.11. The study outcomes were 30-day mortality and 1-year mortality from AIS. Cox proportional hazard models were utilized to assess the association between RPR and mortality. Subgroup analyses were applied based on age, tissue-type plasminogen activator (IV-tPA), endovascular treatment, and myocardial infarction. RESULTS: A total of 1,358 patients were included in the study. Short- and long-term mortality occurred in 375 (27.61%) and 560 (41.24%) AIS patients, respectively. A high RPR was significantly associated with increased 30-day [hazard ratio (HR): 1.45, 95% confidence interval (CI): 1.10 to 1.92, P = 0.009] and 1-year mortality (HR: 1.54, 95%CI: 1.23 to 1.93, P < 0.001) in AIS patients. Meanwhile, RPR was found to be significantly related to 30-day mortality in AIS patients aged < 65 years (HR: 2.19, 95% CI: 1.17 to 4.10, P = 0.014), without IV-tPA use (HR: 1.42, 95% CI: 1.05 to 1.90, P = 0.021), without using endovascular treatment (HR: 1.45, 95% CI: 1.08 to 1.94, P = 0.012), and without myocardial infarction (HR: 1.54, 95% CI: 1.13 to 2.10, P = 0.006). Additionally, RPR was associated with 1-year mortality in AIS patients aged < 65 years (HR: 2.54, 95% CI: 1.56 to 4.14, P < 0.001), aged ≥ 65 years (HR: 1.38, 95% CI: 1.06 to 1.19, P = 0.015), with (HR: 1.46, 95% CI: 1.15 to 1.85, P = 0.002) and without using IV-tPA (HR: 2.30, 95% CI: 1.03 to 5.11, P = 0.041), without using endovascular treatment (HR: 1.56, 95% CI: 1.23 to 1.96, P < 0.001), and without myocardial infarction (HR: 1.68, 95% CI: 1.31 to 2.15, P < 0.001). CONCLUSION: Elevated RPR is associated with a high risk of short-term and long-term mortality in AIS.

Effects of menthol on thirst during surgery patients fasting: A systematic review and meta-analysis of randomized controlled studies.

AIMS: We aim to analyse the effect of menthol on thirst intensity and thirst comfort in surgical patients. BACKGROUND: Menthol has achieved good results in quenching thirst in patients in intensive care units, but its safety and reliability in perioperative fasting patients are unknown. DESIGN: A systematic review with meta-analysis of intervention studies was performed. DATA SOURCES: We used Chinese and English databases from their dates of inception to May 2022. Literature was retrieved from PubMed, Web of Science, Cochrane Library, Embase, CINHAL, SinoMed, CNKI, Wanfang and VIP database. REVIEW METHODS: Two reviewers independently examined the records according to the eligibility criteria and extracted the data of each included study. RESULTS: A total of seven studies were identified in this review, which included 537 surgical patients. Overall, menthol reduced thirst intensity in surgical patients and decreased thirst discomfort. Further subgroup analysis revealed that the menthol intervention significantly improved thirst intensity in surgical patients during preoperative and postoperative fasting periods. The Egger's tests showed no significant bias (p = 0.113 and 0.553, thirst intensity and thirst discomfort, respectively). CONCLUSION: Menthol intervention effectively improved thirst intensity and thirst discomfort during fasting in surgical patients, but more large-scale, multicentre randomized controlled trials are required to confirm these findings further.

Effect of elevated fasting blood glucose level on the 1-year mortality and sequelae in hospitalized COVID-19 patients: A bidirectional cohort study.

To observe the predictive effect of fasting blood glucose (FBG) level on the prognosis, clinical sequelae, and pulmonary absorption in hospitalized coronavirus disease 2019 (COVID-19) patients with and without a history of diabetes, respectively, and to evaluate the correlation between the dynamic changes of FBG and poor prognosis. In this bidirectional cohort study, we enrolled 2545 hospitalized COVID-19 patients (439 diabetics and 2106 without a diabetic history) and followed up for 1 year. The patients were divided according to the level of admission FBG. The dynamic changes of FBG were compared between the survival and the death cases. The prediction effect of FBG on 1-year mortality and sequelae was analyzed. The 1-year all cause mortality rate and in-hospital mortality rate of COVID-19 patients were J-curve correlated with FBG (p < 0.001 for both in the nondiabetic history group, p = 0.004 and p = 0.01 in the diabetic history group). FBG ≥ 7.0 mmol/L had a higher risk of developing sequelae (p = 0.025) and have slower recovery of abnormal lung scans (p < 0.001) in patients who denied a history of diabetes. Multivariable Cox regression analysis showed that FBG ≥ 7.0 mmol/L was an independent risk factor for the mortality of COVID-19 regardless of the presence or deny a history of diabetes (hazard atio [HR] = 10.63, 95% confidence interval [CI]: 7.15-15.83, p < 0.001; HR = 3.9, 95% CI: 1.56-9.77, p = 0.004, respectively). Our study shows that FBG ≥ 7.0 mmol/L can be a predictive factor of 1-year all-cause mortality in COVID-19 patients, independent of diabetes history. FBG ≥ 7.0 mmol/L has an advantage in predicting the severity, clinical sequelae, and pulmonary absorption in COVID-19 patients without a history of diabetes. Early detection, timely treatment, and strict control of blood glucose when finding hyperglycemia in COVID-19 patients (with or without diabetes) are critical for their prognosis.

Deep learning algorithms for magnetic resonance imaging of inflammatory sacroiliitis in axial spondyloarthritis.

OBJECTIVE: The aim of this study was to develop a deep learning algorithm for detection of active inflammatory sacroiliitis in short tau inversion recovery (STIR) sequence MRI. METHODS: A total of 326 participants with axial SpA, and 63 participants with non-specific back pain (NSBP) were recruited. STIR MRI of the SI joints was performed and clinical data were collected. Region of interests (ROIs) were drawn outlining bone marrow oedema, a reliable marker of active inflammation, which formed the ground truth masks from which 'fake-colour' images were derived. Both the original and fake-colour images were randomly allocated into either the training and validation dataset or the testing dataset. Attention U-net was used for the development of deep learning algorithms. As a comparison, an independent radiologist and rheumatologist, blinded to the ground truth masks, were tasked with identifying bone marrow oedema in the MRI scans. RESULTS: Inflammatory sacroiliitis was identified in 1398 MR images from 228 participants. No inflammation was found in 3944 MRI scans from 161 participants. The mean sensitivity of the algorithms derived from the original dataset and fake-colour image dataset were 0.86 (0.02) and 0.90 (0.01), respectively. The mean specificity of the algorithms derived from the original and the fake-colour image datasets were 0.92 (0.02) and 0.93 (0.01), respectively. The mean testing dice coefficients were 0.48 (0.27) for the original dataset and 0.51 (0.25) for the fake-colour image dataset. The area under the curve of the receiver operating characteristic (AUC-ROC) curve of the algorithms using the original dataset and the fake-colour image dataset were 0.92 and 0.96, respectively. The sensitivity and specificity of the algorithms were comparable with the interpretation by a radiologist, but outperformed that of the rheumatologist. CONCLUSION: An MRI deep learning algorithm was developed for detection of inflammatory sacroiliitis in axial SpA.

Tailoring Dirac Fermions by In-Situ Tunable High-Order Moiré Pattern in Graphene-Monolayer Xenon Heterostructure.

We report an experimental study of a high-order moiré pattern formed in graphene-monolayer xenon heterostructure. The moiré period is in situ tuned from few nanometers to +∞, by adjusting the lattice constant of the xenon monolayer through annealing. Using angle-resolved photoemission spectroscopy, we observe that Dirac node replicas move closer and finally overlap with a gap opening, as the moiré pattern expands to +∞ and evolves into a Kekulé distortion. A moiré Hamiltonian coupling Dirac fermions from different valleys explains experimental results and indicates narrow moiré band. Our Letter demonstrates a platform to study continuous evolution of the moiré pattern, and provides an unprecedented approach for tailoring Dirac fermions with tunable intervalley coupling.

One-year mortality and consequences of COVID-19 in cancer patients: A cohort study.

The 1-year mortality and health consequences of COVID-19 in cancer patients are relatively underexplored. In this multicenter cohort study, 166 COVID-19 patients with cancer were compared with 498 non-cancer COVID-19 patients and 498 non-COVID cancer patients. The 1-year all-cause mortality and hospital mortality rates in Cancer COVID-19 Cohort (30% and 20%) were significantly higher than those in COVID-19 Cohort (9% and 8%, both P < .001) and Cancer Cohort (16% and 2%, both P < 0.001). The 12-month all-cause post-discharge mortality rate in survival discharged Cancer COVID-19 Cohort (8%) was higher than that in COVID-19 Cohort (0.4%, P < .001) but similar to that in Cancer Cohort (15%, P = .084). The incidence of sequelae in Cancer COVID-19 Cohort (23%, 26/114) is similar to that in COVID-19 Cohort (30%, 130/432, P = .13). The 1-year all-cause mortality was high among patients with hematologic malignancies (59%), followed by those who have nasopharyngeal, brain, and skin tumors (45%), digestive system neoplasm (43%), and lung cancers (32%). The rate was moderate among patients with genitourinary (14%), female genital (13%), breast (11%), and thyroid tumors (0). COVID-19 patients with cancer showed a high rate of in-hospital mortality and 1-year all-cause mortality, but the 12-month all-cause post-discharge mortality rate in survival discharged cancer COVID-19 patients was similar to that in Cancer Cohort. Comparing to COVID-19 Cohort, risk stratification showed that hematologic, nasopharyngeal, brain, digestive system, and lung tumors were high risk (44% vs 9%, P < 0.001), while genitourinary, female genital, breast, and thyroid tumors had moderate risk (10% vs 9%, P = .85) in COVID-19 Cancer Cohort. Different tumor subtypes had different effects on COVID-19. But if cancer patients with COVID-19 manage to survive their COVID-19 infections, then long-term mortality appears to be similar to the cancer patients without COVID-19, and their long-term clinical sequelae were similar to the COVID-19 patients without cancer.

Comparative study of hospitalized children with acute respiratory distress syndrome caused by SARS-CoV-2 and influenza virus.

BACKGROUND: Since the outbreak of coronavirus disease 2019 in December 2019, more than 8 million cases have occurred worldwide as of June 16, 2020. However, it is important to distinguish COVID-19 from other respiratory infectious diseases, such as influenza. Here, we comparatively described the clinical characteristics of children with COVID-19 and paediatric patients with influenza. METHODS: In this retrospective, single-centre study, we reviewed the electronic medical records of 585 paediatric patients with COVID-19 or influenza in Wuhan Children's Hospital, China. Clinical and epidemiological characteristics, laboratory findings, and clinical outcomes were comparatively analysed. RESULTS: The median ages were 6.96 years (IQR, 2-10.81) for children with confirmed COVID-19, 2.67 years (IQR, 1.03-15.25) for those with influenza A and 3.67 years (IQR, 1.62-5.54) for those with influenza B. Fever was a symptom in 84 (34.7%) COVID-19 cases, 132 (70.21%) influenza A cases and 111 (74.50%) influenza B cases. The median length of stay (LOS) was 11 (8-15) days for paediatric COVID-19 patients, 4 (3-6) days for influenza A patients and 5 (3-6) days for influenza B patients. Twenty-six (13.98%) influenza A patients and 18 (12.59%) influenza B patients presented with decreased white blood cell counts, while 13 (5.33%) COVID-19 patients presented with decreased white blood cell counts. Eight (3.28%) COVID-19 patients, 23 (12.71%) influenza A patients and 21 (14.79%) influenza B patients experienced lymphocytopenia. Acute cardiac injury occurred in 18 (7.29%) COVID-19 patients, while 37 (19.68%) influenza A and 27 (18.12%) influenza B patients had acute cardiac injury. CONCLUSION: In this study, the illnesses of children with COVID-19 were demonstrated to be less severe than those of paediatric patients with influenza, and COVID-19 patients had milder illness and fewer complications.

Clinical and Epidemiological Features of 46 Children <1 Year Old With Coronavirus Disease 2019 in Wuhan, China: A Descriptive Study.

The number of coronavirus disease 2019 (COVID-19) cases has exceeded 10 million. However, little is known about the epidemiology and clinical characteristics of COVID-19 infants. We collected medical information of 46 confirmed patients (<1 year old) and retrospectively analyzed epidemiological history, clinical symptoms, and laboratory test results. The median age was 5 (interquartile range, 2-7) months. Sixteen cases had fever and 27 cases had cough. Moderate disease was present in 40 cases and cardiac injury occurred in 38 cases, following by liver dysfunction in 20 cases and lymphocytosis in no cases. Of all infant patients, 2 received invasive mechanical ventilation and 1 died with multiple organ dysfunction syndrome.

Characteristics of Household Transmission of COVID-19.

BACKGROUND: Since December 2019, SARS-CoV-2 has extended to most parts of China with >80 000 cases and to at least 100 countries with >60 000 international cases as of 15 March 2020. Here we used a household cohort study to determine the features of household transmission of COVID-19. METHODS: A total of 105 index patients and 392 household contacts were enrolled. Both index patients and household members were tested by SARS-CoV-2 RT-PCR. Information on all recruited individuals was extracted from medical records and confirmed or supplemented by telephone interviews. The baseline characteristics of index cases and contact patients were described. Secondary attack rates of SARS-CoV-2 to contact members were computed and the risk factors for transmission within the household were estimated. RESULTS: Secondary transmission of SARS-CoV-2 developed in 64 of 392 household contacts (16.3%). The secondary attack rate to children was 4% compared with 17.1% for adults. The secondary attack rate to the contacts within the households with index patients quarantined by themselves since onset of symptoms was 0% compared with 16.9% for contacts without quarantined index patients. The secondary attack rate to contacts who were spouses of index cases was 27.8% compared with 17.3% for other adult members in the households. CONCLUSIONS: The secondary attack rate of SARS-CoV-2 in household is 16.3%. Age of household contacts and spousal relationship to the index case are risk factors for transmission of SARS-CoV-2 within a household. Quarantine of index patients at home since onset of symptoms is useful to prevent the transmission of SARS-Co-2 within a household.

Clinical outcomes of anterior correction and reconstruction for neurofibromatosis-associated severe cervical kyphotic deformity.

PURPOSE: To assess the clinical outcome of anterior correction and reconstruction for severe cervical kyphotic deformity due to neurofibromatosis type 1 (NF-1). METHODS: In this study, we reviewed a series of seven patients who underwent anterior procedures for correction of NF-1-associated cervical kyphotic deformity. After continuous preoperative skull traction, all patients received anterior corpectomy and fusion (ACCF), anterior discectomy and fusion (ACDF), or combined ACCF and ACDF for surgical correction and reconstruction. Pre- and postoperative local and global Cobb angles, correction rate, sagittal vertical axis (SVA), and T1-slope were assessed by X-ray. Japanese Orthopaedic Association (JOA) score, JOA recovery rate, visual analog scale (VAS), and Neck Disability Index (NDI) scores were recorded to assess the outcome. RESULTS: Kyphosis was corrected successfully in all patients in terms of local and global Cobb angles (P < 0.05), with a correction rates of 83.1% (range, 66.0 to 115.5%) and 88.6% (range, 61.1 to 125.0%), respectively. JOA scores of patients were improved from preoperative 10.4 (range, 6 to 14) to postoperative 15.4 (range, 14 to 17), with a recovery rate as 77.6% (range, 66.7 to 100%). NDI scores were reduced from preoperative 25.1 (range, 13 to 35) to postoperative 8.7 (range, 5 to 12). VAS scores were reduced from preoperative 7.0 (range, 4 to 9) to postoperative 2.3 (range, 1 to 3). CONCLUSION: This study has demonstrated that anterior correction and reconstruction is an alternative option for the treatment of NF-1-associated severe cervical kyphosis when deformity is localized, flexible, or fixed.

Association of dietary antioxidant intake with depression risk and all-cause mortality in people with prediabetes.

People with diabetes has an elevated risk of depression, and depression contributes to a worse prognosis for people with diabetes. Dietary antioxidants have been shown to reduce the risk of depression in the general population. Therefore, we hypothesized that dietary antioxidants would also help to reduce the risk of depression and all-cause mortality in people with prediabetes. A total of 8789 participants aged 20 years and older from the 2005-2018 National Health and Nutrition Examination Surveys who met the diagnostic criteria for prediabetes were included in our study. The associations between six dietary antioxidant intakes and the composite dietary antioxidant index (CDAI) with depression risk and all-cause mortality were assessed using weighted logistic and Cox regression. Possible nonlinear associations were further explored using restricted cubic spline. To ensure the reliability of the findings, the multiple imputations by chained equation were applied to missing covariates to avoid potential bias. Our study found that moderate dietary antioxidant intake prevents depression and improves prognosis in people with prediabetes. Moreover, a CDAI score near three allows for maximum benefit. Our findings could provide clues for early intervention in people with diabetes.

Advanced Strategies of CAR-T Cell Therapy in Solid Tumors and Hematological Malignancies.

Chimeric antigen receptor T-cells, known as CAR-T cells, represent a promising breakthrough in the realm of adoptive cell therapy. These T-cells are genetically engineered to carry chimeric antigen receptors that specifically target tumors. They have achieved notable success in the treatment of blood-related cancers, breathing new life into this field of medical research. However, numerous obstacles limit chimeric antigen receptors T-cell therapy's efficacy, such as it cannot survive in the body long. It is prone to fatigue and exhaustion, leading to difficult tumor elimination and repeated recurrence, affecting solid tumors and hematological malignancies. The challenges posed by solid tumors, especially in the context of the complex solid-tumor microenvironment, require specific strategies. This review outlines recent advancements in improving chimeric antigen receptors T-cell therapy by focusing on the chimeric antigen receptors protein, modifying T-cells, and optimizing the interaction between T-cells and other components within the tumor microenvironment. This article aims to provide an extensive summary of the latest discoveries regarding CAR-T cell therapy, encompassing its application across various types of human cancers. Moreover, it will delve into the obstacles that have emerged in recent times, offering insights into the challenges faced by this innovative approach. Finally, it highlights novel therapeutic options in treating hematological and solid malignancies with chimeric antigen receptors T-cell therapies.

Recent Advancement in Inhaled Nano-drug Delivery for Pulmonary, Nasal, and Nose-to-brain Diseases.

Pulmonary, nasal, and nose-to-brain diseases involve clinical approaches, such as bronchodilators, inhaled steroids, oxygen therapy, antibiotics, antihistamines, nasal steroids, decongestants, intranasal drug delivery, neurostimulation, and surgery to treat patients. However, systemic medicines have serious adverse effects, necessitating the development of inhaled formulations that allow precise drug delivery to the airways with minimum systemic drug exposure. Particle size, surface charge, biocompatibility, drug capacity, and mucoadhesive are unique chemical and physical features that must be considered for pulmonary and nasal delivery routes due to anatomical and permeability considerations. The traditional management of numerous chronic diseases has a variety of drawbacks. As a result, targeted medicine delivery systems that employ nanotechnology enhancer drug efficiency and optimize the overall outcome are created. The pulmonary route is one of the most essential targeted drug delivery systems because it allows the administering of drugs locally and systemically to the lungs, nasal cavity, and brain. Furthermore, the lungs' beneficial characteristics, such as their ability to inhibit first-pass metabolism and their thin epithelial layer, help treat several health complications. The potential to serve as noninvasive self-administration delivery sites of the lung and nasal routes is discussed in this script. New methods for treating respiratory and some systemic diseases with inhalation have been explored and highlight particular attention to using specialized nanocarriers for delivering various drugs via the nasal and pulmonary pathways. The design and development of inhaled nanomedicine for pulmonary, nasal, and respiratory medicine applications is a potential approach for clinical translation.

Research on the relation between hydro-chemical and geological characteristics in karst area: Case study in Zhong Liang Mountain, Southwest China.

Karst groundwater, which is one of most important drinking water sources, is vulnerable to be polluted as its closed hydraulic relation with surface water. Thus, it is very important to identify the groundwater source to control groundwater pollution. The Pearson correlation coefficient among major ions (Na + K+, Ca2+, Mg2+, HCO3 -, SO4 2-, and Cl-) was employed to deduce the groundwater types in Zhong Liang Mountain, Southwest China. Then, the combined method of principal component analysis and cluster analysis were employed to identify the groundwater sources in a typical karst region of southwest China. The results shown that (1) the high positive correlation between cations and anions indicated the water-rock reaction of Ca-HCO3, Ca-SO4, (Na + K)-Cl, and Mg-SO4. (2) The major two principal components that would represent water-rock reaction of CaSO4 and Ca-HCO3 would, respectively, explain 60.41% and 31.80% of groundwater information. (3) Based on the two principal components, 33 groundwater samples were clustered into eight groups through hierarchical clustering, each group has similar water-rock reaction. The findings would be employed to forecast the surge water, that was an important work for tunnel construction and operation. PRACTITIONER POINTS: The components of groundwater was highly correlated with water-rock reaction. The principal component analysis screens the types of groundwater. The cluster analysis identifies the groundwater sources.

Construction and application of prone position ventilation management scheme for severe COVID-19 patients.

Background: Prone position ventilation (PPV) can significantly improve oxygenation index and blood oxygen saturation in most (70%-80%) patients with acute respiratory distress syndrome. However, although PPV is not an invasive procedure, there are many potential PPV-related complications, such as nerve compression, crush injury, venous stasis (e.g., facial oedema), pressure sores, retinal damage, vomiting, and arrhythmia, with an incidence of up to 56.9%. Nursing managers have focused on reducing the occurrence of PPV-related complications and improving safety. Objective: To construct a prone ventilation management scheme for patients with severe coronavirus disease 2019 (COVID-19) and analyse its application effect. Methods: Based on a previous evidence-based study combined with the COVID-19 Diagnosis and Treatment Protocol (Trial Edition 9), a prone ventilation management protocol for severe COVID-19 was formulated and applied to COVID-19 patients in the intensive care unit of a designated hospital. A prospective self-control study was used to compare changes in the oxygenation index and other outcome indicators before and after the intervention. Results: The oxygenation index of patients after intervention (321.22 ± 19.77 mmHg) was significantly higher (p < 0.05) than before intervention (151.59 ± 35.49 mmHg). The difference in oxygenation index in different prone position ventilation durations was statistically significant (p < 0.05). Nursing quality evaluation indicators showed that the implementation rate of gastric residual volume assessment was 100% and the incidence of occupational exposure and cross-infection was 0%; the incidences of pressure ulcers, drug extravasation, and facial oedema were 13.64% (3/22), 4.54% (1/22), and 4.54% (1/22), respectively. The incidence of unplanned extubation, aspiration, and falls/falls was 0%.

LncRNA GASL1 inhibits tumor growth in gastric carcinoma by inactivating the Wnt/ß-catenin signaling pathway.

Growth arrest associated lncRNA 1 (GASL1) is a newly discovered tumor suppressor long non-coding RNA (lncRNA) in osteosarcoma; however its role in other malignancies remains unknown. The aim of the present study was to investigate the involvement of GASL1 in gastric cancer. In the current study, gastric cancer tissue and adjacent healthy tissue samples were collected from patients with gastric carcinoma, and blood samples were collected from patients with gastric carcinoma and healthy controls to detect the expression of serum GASL1. All patients were followed up for 5 years and the diagnostic and prognostic value of GASL1 for gastric carcinoma was evaluated by ROC and survival curve analyses, respectively. The chi-square test was used to analyze the correlation between serum levels of GASL1 and the clinicopathological features of patients with gastric carcinoma. A GASL1 expression vector and GASL1 small interfering RNA were transfected into gastric cancer cell lines and the effects on ß-catenin expression and cell proliferation were examined by western blot and cell proliferation assays, respectively. The expression level of lncRNA GASL1 was significantly downregulated in gastric cancer tissues compared with adjacent normal tissues from patients with gastric carcinoma. In addition, serum levels of GASL1 were significantly decreased in patients with gastric carcinoma when compared with healthy controls. Serum GASL1 levels distinguished patients with gastric carcinoma from healthy controls, and low expression levels of GASL1 were associated with decreased postoperative survival time. GASL1 overexpression downregulated, while GASL1 knockdown upregulated ß-catenin expression. GASL1 overexpression inhibited, and GASL1 knockdown promoted gastric cancer cell proliferation. In addition, treatment with a Wnt agonist demonstrated no significant effect on GASL1 expression, however the inhibitory effect of GASL1 overexpression on cell proliferation was reduced following treatment with the Wnt agonist. In conclusion, the GASL1 lncRNA may inhibit tumor growth in patients with gastric carcinoma by inactivating the Wnt/ß-catenin signaling pathway.

An exploratory randomized controlled study on early application of Shenfu injection to prevent septic cardiomyopathy / 中华急诊医学杂志

Objective:To observe the clinical effect of Shenfu injection in preventing septic cardiomyopathy (SIC) in septic patients.Methods:From June 2022 to January 2023, patients with sepsis or septic shock who did not develop SIC were randomly divided into treatment group and control group according to the ratio of 1:1. In the treatment group, Shenfu injection (50 mL) was pumped intravenously once every 12 hours for 5 days. In the control group, 50 mL of normal saline was pumped intravenously once every 12 hours, and the course of treatment was 5 days. The primary end point was the incidence of SIC in the first 5 days. The secondary end points were the application time of vasoactive drugs, fluid balance in the previous week, hospitalization time in ICU, total ventilation time and 28-day mortality.Results:112 patients were randomly divided into two groups. Seven patients in the treatment group were excluded twice, and finally 49 patients were included in the analysis, while six patients in the control group were excluded twice and 50 patients included in the analysis. The total incidence of SIC in the treatment group within 5 days was significantly lower than that in the control group (42.9% vs. 64.0%, P = 0.035). Among them, the left ventricular systolic dysfunction in the treatment group was significantly lower than that in the control group (24.5% vs 52.0%, P=0.005), and there was no significant difference in the incidence of left ventricular diastolic dysfunction between the two groups. The incidence of right ventricular dysfunction in the control group was 28.0%, which was significantly higher than 10.2% in the treatment group ( P = 0.025). The duration of using vasoconstrictors in the treatment group was 75(48, 97) hours, which was significantly lower than 97(66, 28) hours in the control group ( P = 0.039). The duration of inotropic drugs use in the treatment group was 32(18, 49) h, which was also significantly shorter than 44(25, 61) h in the control group ( P=0.046). The fluid balance of the control group in the first week was (1 260±850) mL, which was significantly higher than (450±520) mL in the treatment group ( P=0.008). There was no statistical difference in ICU stay, total ventilation time and 28-day mortality between the two groups (all P > 0.05). Conclusion:Early application of Shenfu injection can significantly reduce the incidence of SIC, accompanied by less use of vasoactive drugs and positive fluid balance, which has a good clinical application prospect.

Neural Mechanisms Underlying the Coughing Reflex / 神经科学通报·英文版

Breathing is an intrinsic natural behavior and physiological process that maintains life. The rhythmic exchange of gases regulates the delicate balance of chemical constituents within an organism throughout its lifespan. However, chronic airway diseases, including asthma and chronic obstructive pulmonary disease, affect millions of people worldwide. Pathological airway conditions can disrupt respiration, causing asphyxia, cardiac arrest, and potential death. The innervation of the respiratory tract and the action of the immune system confer robust airway surveillance and protection against environmental irritants and pathogens. However, aberrant activation of the immune system or sensitization of the nervous system can contribute to the development of autoimmune airway disorders. Transient receptor potential ion channels and voltage-gated Na+ channels play critical roles in sensing noxious stimuli within the respiratory tract and interacting with the immune system to generate neurogenic inflammation and airway hypersensitivity. Although recent studies have revealed the involvement of nociceptor neurons in airway diseases, the further neural circuitry underlying airway protection remains elusive. Unraveling the mechanism underpinning neural circuit regulation in the airway may provide precise therapeutic strategies and valuable insights into the management of airway diseases.
