Acute ischemic stroke (AIS) is one of the leading causes of death and disability in the global population, and its pathological mechanism is closely associated with inflammation and coagulation-nutrient imbalance. The C-reactive protein/albumin ratio (CAR) and fibrinogen/albumin ratio (FAR), as novel composite inflammatory markers, provide more comprehensive outcome prediction tools in patients with AIS by integrating information on systemic inflammation severity and nutritional status. This article reviews the clinical value of CAR and FAR in predicting early neurological deterioration, hemorrhagic transformation, stroke associated pneumonia, and poor outcome in patients with AIS, providing a scientific basis for optimizing early risk stratification and clinical intervention in patients with AIS.

Objective To explore the humidification effects between the humidifiers Venturi high-flow oxygen therapy(HVHF)and the high-flow humidified oxygen therapy in the treatment of patients with tracheotomy after the withdrawal of ventilator,and analyse the humidification performance and effect of airway humidification on the two oxygen therapies hence to provide an objective basis for selection of a humidified oxygen therapy.Methods A total of 146 ICU patients who had tracheotomy and completely withdrawal of ventilator in a general hospital in Shenzhen from July 2020 to December 2021 were randomly divided into trial group(n=73)and control group(n=73).With identical speed of airflow,patients in the trial groups were treated with HVHF and the patients of control group were offered with high-flow humidified oxygen therapy via AIRVOTM2.Data of the two groups were compared at the time points of days 0,2,7 and 14 in terms of absolute humidity(AH),relative humidity(RH),temperature(T)),sputum viscosity,arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2),oxygenation index(PaO2/FIO2)and the incidence of pulmonary infection.Results In the study,total of 61 patients in the control group and 72 patients in the trial group completed the high-flow humidified oxygen therapies,due to tubing detachments in 12 and 1 patients in the two groups,respectively.Repeated-Measures ANOVA analysis showed that,in both groups,there was a time effect(P<0.05)between the absolute humidity,relative humidity,temperature of the gas,PaO2,PaCO2,and PaO2/FiO2 at different time points.PaO2 and PaO2/FiO2 in both groups showed interactions at different time points(P<0.05).PaO2 and PaO2/FiO2 in the trial group were better than those in the control group at the time points of days 2,7 and 14(P<0.05).On days 2,7 and 14,the viscosity of sputum in the intervention group was better than that in the control group,and the incidence of pulmonary infection in the trial group was significantly lower than that in the control group(P<0.05).Conclusions HVHF and AIRVOTM2 both exhibit no obvious difference in gas humidification via high-flow humidification oxygen therapy in the patients with tracheotomy after withdrawal of ventilator.However,HVHF is superior to AIRVOTM2 in terms of improving airway humidification and oxygenation as well as reducing lung infection.Therefore,it is suggested that an HVHF is preferable for high-flow humidified oxygen therapy in treating the patients with tracheotomy after the withdrawal of ventilator.

Objective:To investigate the application value of auricular point pressing with beans combined with Chinese medicine for rehabilitation in older adults after total hip arthroplasty.Methods:This is a prospective case-control study. A total of 80 older adult patients with femoral neck fractures who underwent total hip arthroplasty at Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from September 2020 to January 2022 were included in this study. These patients were randomly divided into a control group and an observation group, with 40 patients per group. The control group underwent conventional interventions, while the observation group underwent auricular point pressing with beans combined with Chinese medicine. Clinical efficacy was compared between the two groups.Results:The overall response rate in the observation group was 85.00% (34/40), which was significantly higher than 65.0% (26/40) in the control group ( χ2 = 4.27, P = 0.036). Before surgery, there were no significant differences in various indicators between the two groups (all P > 0.05). At 2 weeks after surgery, the hemoglobin level and Harris scores in the observation group were higher than those in the control group ( t = -7.11, -5.81, both P < 0.05). At 1 and 3 days and 2 weeks after surgery, the D-dimer level, prothrombin time, activated partial thrombin time, thrombin time, Visual Analogue Scale score, and Pittsburgh Sleep Quality Index (PSQI) in the observation group were significantly lower than those in the control group (all P < 0.05). At 3 days and 2 weeks after surgery, C-reactive protein, thigh and calf circumference of the affected limb in the observation group were significantly lower than those in the control group ( t = 2.34, 6.85, 4.47, 3.89, 6.63, 4.35, all P < 0.05). After surgery, the time to get off the bed and the length of hospital stay in the observation group were (3.58 ± 2.43) days and (7.14 ± 2.18) days, respectively, which were significantly shorter than (5.47 ± 2.35) days and (9.13 ± 2.14) days in the control group ( t = 3.54, 4.12, both P < 0.001). The incidence of postoperative deep vein thrombosis in the observation group was 5.00% (2/40), which was significantly lower than 10.00% (4/40) in the control group ( χ2 = 0.72, P = 0.396). Conclusion:Auricular point pressing with beans combined with Chinese medicine can promote rapid rehabilitation of older adult patients with femoral neck fractures after total hip arthroplasty.

Light adaptation enables the vertebrate visual system to operate over a wide range of ambient illumination. Regulation of phototransduction in photoreceptors is considered a major mechanism underlying light adaptation. However, various types of neurons and glial cells exist in the retina, and whether and how all retinal cells interact to adapt to light/dark conditions at the cellular and molecular levels requires systematic investigation. Therefore, we utilized single-cell RNA sequencing to dissect retinal cell-type-specific transcriptomes during light/dark adaptation in mice. The results demonstrated that, in addition to photoreceptors, other retinal cell types also showed dynamic molecular changes and specifically enriched signaling pathways under light/dark adaptation. Importantly, Müller glial cells (MGs) were identified as hub cells for intercellular interactions, displaying complex cell‒cell communication with other retinal cells. Furthermore, light increased the transcription of the deiodinase Dio2 in MGs, which converted thyroxine (T4) to active triiodothyronine (T3). Subsequently, light increased T3 levels and regulated mitochondrial respiration in retinal cells in response to light conditions. As cones specifically express the thyroid hormone receptor Thrb, they responded to the increase in T3 by adjusting light responsiveness. Loss of the expression of Dio2 specifically in MGs decreased the light responsive ability of cones. These results suggest that retinal cells display global transcriptional changes under light/dark adaptation and that MGs coordinate intercellular communication during light/dark adaptation via thyroid hormone signaling.

Objective:To explore the risk factors for 30-day death in emergency department patients, and then construct a prediction model and validate it using nomogram.Methods:A retrospective cohort study was conducted. The clinical data of 1 091 patients admitted to the emergency department of the First People's Hospital of Changde from January 1 to June 30, 2021 was collected, including 741 patients from January 1 to March 31 in the development group and 350 patients from April 1 to June 30 in the validation group. General information, first vital signs admitted to the emergency department, and laboratory results were collected, the modified early warning score (MEWS) was calculated, and 30-day outcomes were recorded. Univariate and multivariate Logistic regression analysis was used to screen out the risk factors of 30-day death. According to the results of multivariate analysis, the nomogram was used to construct a 30-day death prediction model. The receiver operator characteristic curve (ROC curve) was used to evaluate the consistency of the prediction model, the calibration of the prediction model was evaluated by the Hosmer-Lemeshow goodness of fit test.Results:A total of 1 091 patients were enrolled. There were 741 patients in the development group, including 356 males and 385 females, aged (51.42±17.33) years old, and the 30-day mortality was 28.88%. There were 350 patients in the validation group, including 188 males and 162 females, aged (52.88±16.11) years old, and the 30-day mortality was 24.00%. The results of the univariate analysis showed that age, primary diagnosis on admission, consciousness, respiratory rate (RR), systolic blood pressure (SBP), heart rate (HR), pulse oxygen saturation (SpO 2), MEWS score, erythrocyte sedimentation rate (ESR), procalcitonin (PCT) and body mass index (BMI) might be the risk factors for 30-day death in patients in the emergency department. The results of the multivariate analysis showed that the MEWS score [odds ratio ( OR) = 14.22, 95% confidence interval (95% CI) was 1.46-138.12], ESR ( OR = 46.71, 95% CI was 20.48-106.53), PCT ( OR = 4.97, 95% CI was 2.46-10.02), BMI (24.0-27.9 kg/m 2: OR = 37.82, 95% CI was 14.69-97.36; ≥28.0 kg/m 2: OR = 62.11, 95% CI was 25.77-149.72) were independent risk factors for 30-day death in the emergency department (all P < 0.05). Using the four variables with the results of multivariate analysis to construct a nomogram prediction model, the area under the ROC curve (AUC) was 0.974 (95% CI was 0.753-0.983) for the development group, and the AUC was 0.963 (95% CI was 0.740-0.975) for the validation group. The Hosmer-Lemeshow test showed no statistically significant difference between the predicted outcome of the nomogram prediction model and the actual occurrence ( χ2 = 1.216, P = 1.270). Conclusion:The prediction model developed by the MEWS score combined with BMI, ESR and PCT can scientifically and effectively predict the 30-day outcome of emergency department patients.

The incidence of prostate cancer is increasing year by year in China. People with BRCA mutation are at high risk of prostate cancer. However, there is no clear and effective treatment for mHSPC with high metastatic load carrying BRCA mutation. In this study, we report a mHSPC patient with high metastatic burden and germline BRCA1 gene mutation who rapidly progressed to mCRPC after traditional CAB therapy and then received ADT combined with abiraterone and achieved significant PSA response, suggesting that ADT combined with abiraterone may be an effective therapy for mHSPC patients with BRCA1 germline mutation.
