Drawing on evidence-based medicine, this review systematically summarizes major literature published between 2019 and 2025, consolidating various AIS treatment approaches to offer a comprehensive reference for clinical practice.

Objective To understand the nursing practice of prone position ventilation for patients with moderate to severe acute respiratory distress syndrome(ARDS)in intensive care unit(ICU)in Shandong province,so as to provide basis for standardizing the nursing practice process of prone position ventilation and carrying out training for hospitals.Methods A self-made questionnaire was used,and convenience sampling was adopted.From September 15th to November 5th,2023,ICU nurses were selected from various hospital levels in Shandong province to investigate the obstructive factors of prone ventilation implementation,the weak links in nursing practice and status,and the occurrence of complications.Results A total of 1 188 questionnaires were collected,of which 991 were valid.92.8%(920/991)of nurses had performed prone position ventilation.The biggest obstacle to the implementation of prone position ventilation was the complexity of patient treatments and multiple devices involved[74.6%(686/920)].Regarding the status of training,90.5%(897/991)of nurses had received training on prone position ventilation and 77.0%(763/991)of nurses felt that training was needed.As for pre-operation assessment,more than 80.0%of nurses evaluated patients'vital signs,airway and secretions and so on,among which the evaluation awareness of analgesia was the worst[81.6%(751/920)].As for the main points of implementation,only 14.0%(129/920)of nurses chose the opposite side of the most important pipeline as the turning direction;48.6%(447/920)of nurses chose the anti-Trendelenburg position;36.3%(334/920)of nurses chose to ventilate≥12 hours.Facial edema[81.7%(752/920)],skin pressure injury[78.9%(726/920)]and eye complication[75.8%(697/920)]were the top 3 most frequent complications.Conclusions ICU nurses'prone position ventilation practices were generally line with the nursing team standard for prone position of adult mechanically ventilated patients and the best evidence recommendation,and needs to be further standardized in aspects of turning direction,position management,ventilation duration,and enteral nutrition management.It is recommended that nursing managers at all levels of hospitals further improve the quality of nursing practice of prone position ventilation according to relevant evidence-based evidence and the actual situation of hospitals.

Objective:To construct the differential diagnosis model of invasive degree of lung adenocarcinoma manifesting as ground-glass nodules (GGNs) with no or little solid component based on energy spectrum CT features, and to provide reference for the follow-up clinical diagnosis and treatment.Methods:A retrospective study was conducted on 145 patients who underwent surgical treatment for lung adenocarcinoma at the 969th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army and Inner Mongolia Hospital of Peking University Cancer Hospital from January 2019 to December 2022, presenting with CT findings of no or little solid component GGNs. The patients were divided into invasive group (51 cases) and microinvasive group (94 cases) based on the invasive degree. Logistic regression was used to conduct a multivariate analysis of factors affecting the differential diagnosis of invasive degree of lung adenocarcinoma manifesting as GGNs with no or little solid component, and construct a logistic regression model. Receiver operator characteristic (ROC) curve was used to analyze the predictive efficiency of each index.Results:Univariate analysis showed that the maximum diameter of nodules ( t=-6.30, P<0.001) , average CT value of nodules ( t=-5.43, P<0.001) , air bronchial sign ( χ2=23.21, P<0.001) , microvascular CT imaging type ( χ2=27.94, P<0.001) were predictors of invasive degree of lung adenocarcinoma manifesting as GGNs with no or little solid component. Multivariate logistic regression analysis showed that the maximum diameter of nodules ( OR=1.72, 95% CI: 1.33-2.23, P<0.001) , average CT value of nodules ( OR=1.01, 95% CI: 1.01-1.02, P<0.001) , air bronchial sign ( OR=4.92, 95% CI: 1.59-15.21, P=0.006) and microvascular CT imaging type Ⅲ ( OR=14.01, 95% CI: 2.97-66.06, P=0.001) were independent predictors of invasive degree of lung adenocarcinoma manifesting as GGNs with no or little solid component. A logistic regression model was constructed based on the results of the above multiple factor analysis: logit ( P) =0.54×maximum diameter of the nodule+0.01×average CT value of the nodule+1.59×air bronchogram sign+2.64×microvascular CT imaging type (type Ⅲ) -3.33. ROC curve analysis showed that the areas under the curve for differential diagnosis of invasive degree of lung adenocarcinoma manifesting as GGNs with no or little solid component based on the maximum diameter of nodules, average CT value of nodules, air bronchogram sign, microvascular CT imaging type, and logistic regression model P-value were 0.759, 0.751, 0.686, 0.741, and 0.918, respectively. Conclusions:The energy spectrum CT features, including the maximum diameter of nodules, average CT value of nodules, air bronchial sign, and microvascular CT imaging type, can be used for differential diagnosis of invasive degree of lung adenocarcinoma manifesting as GGNs with no or little solid component. The logistic regression model constructed using the above four factors has shown good performance in predicting the invasive degree of patient.

Objective To evaluate the clinical efficacy of Shengqing Jiangzhuo(lifting lucid yang and lowering turbid yin)Acupuncture Method,based on the"turbidity-clearness interaction"theory,combined with western medicine in treating gouty nephropathy(GN)patients with damp-heat accumulation syndrome.Methods A total of 117 patients diagnosed with GN from September 2023 to September 2024 at the First Affiliated Hospital of Guangzhou University of Chinese Medicine Chongqing Hospital were enrolled and randomly divided into three groups,with 39 cases in each group.The western medicine group received Febuxostat Tablets,the control group was given western medicine+conventional acupuncture,and observation group was given western medicine+Shengqing Jiangzhuo Acupuncture Method.All groups received 4 weeks of treatment.Clinical efficacy,traditional Chinese medicine(TCM)syndrome scores,visual analogue scale(VAS)of pain scores,and laboratory parameters—including serum uric acid(UA),blood urea nitrogen(BUN),creatinine(Scr),estimated glomerular filtration rate(eGFR),β2-microglobulin(β2-MG),24-hour urinary protein(24h-UTP),cystatin C(CysC)were assessed.The erythrocyte sedimentation rate(ESR),and C-reactive protein(CRP)were compared before and after treatment.Results(1)The total effective rate was 71.79%(28/39)in the western medicine group,84.62%(33/39)in the control group,and 92.31%(36/39)in the observation group.The observation group demonstrated statistically significant superiority over the western medicine group(P＜0.05),while showing marginally better efficacy than the control group without statistical significance(P＞0.05).(2)After treatment,all three groups exhibited significant improvements in ESR,CRP,and UA levels(P＜0.05).The observation group significantly outperformed the other two groups in reducing ESR and CRP levels(P＜0.05),and was statistically superior to the western medicine group in lowering UA levels(P＜0.05),though no significant difference was observed versus the control group for UA improvement(P＞0.05).The control group showed significantly greater reductions in ESR,CRP,and UA levels than the western medicine group(P＜0.05).(3)After treatment,Scr,BUN,and eGFR levels were significantly improved in all groups(P＜0.05).The observation group achieved significantly better improvements in Scr and eGFR than the other two groups(P＜0.05).However,no statistical difference existed between the control and western medicine groups for Scr or eGFR enhancement(P＞0.05).No intergroup differences were detected in BUN improvement(P＞0.05).(4)Significant differences emerged in β2-MG and CysC levels among all groups after treatment(P＜0.05).Both observation and control groups demonstrated statistically significant improvements in 24-hour 24h-UTP(P＜0.05),whereas the western medicine group showed no significant change(P＞0.05).The observation group significantly outperformed the other groups in reducing 24h-UTP and β2-MG levels(P＜0.05),and was superior to the western medicine group in lowering CysC(P＜0.05),though no difference versus the control group was observed for CysC reduction(P＞0.05).The control group showed no statistical advantage over the western medicine group in improving 24h-UTP,β 2-MG,or CysC(P＞0.05).(5)After treatment,TCM syndrome scores and VAS scores were significantly improved in all groups(P＜0.05).The observation group achieved significantly greater reductions in TCM syndrome scores and VAS scores than the western medicine group(P＜0.05).The control group showed statistically superior VAS score improvement versus the western medicine group(P＜0.05),but no significant differences emerged in TCM syndrome score improvement compared to either group(P＞0.05).No statistical difference existed between observation and control groups for VAS score reduction(P＞0.05).Conclusion Shengqing Jiangzhuo Acupuncture Method,grounded in the"turbidity-clearness interaction"theory,effectively reduces serum UA,controls inflammation,and preserves renal function in damp-heat accumulation type of GN,demonstrating significant therapeutic benefits.

Objective To investigate the inhibitory effect and molecular mechanism of Huaier granule on the growth of sorafenib resistant hepatocellular carcinoma (HCC) cells. Methods The gradient concentration of Huaier granule was used to treat HCC cells, and the effect of Huaier granule on the proliferation, migration and invasion of sorafenib resistant HCC cells was analyzed. Bioinformatics methods were used to analyze the possible interaction between microRNA-31-5p (miR-31-5p) and sprouty-related proteins with an EVH1 domain 1 (SPRED1). The expression levels of miR-31-5p and SPRED1 in HCC cells were detected by real time fluorescence quantitative polymerase chain reaction (qRT-PCR); cell viability, proliferation, migration, invasion and apoptosis were detected by CCK-8, colony formation, scratch healing, Transwell and flow cytometry; RNA immunoprecipitation (RIP) assay and dual luciferase assay were used to verify the binding relationship between miR-31-5p and SPRED1. Results Huaier granule could significantly inhibit the proliferation, migration and invasion of sorafenib resistant HCC cells, and induce apoptosis. Bioinformatics analysis showed that miR-31-5p was highly expressed in HCC, and Huaier granule was able to down-regulate the expression of miR-31-5p, inhibit the proliferation and metastasis of sorafenib resistant HCC cells, and induce apoptosis; miR-31-5p showed a targeted inhibition effect on the expression of SPRED1. SPRED1 was down-regulated in HCC, and overexpression of SPRED1 was able to reverse the promoting effect of overexpression of miR-31-5p on proliferation and metastasis of sorafenib resistant HCC. Conclusion Huaier granule can inhibit sorafenib resistant HCC metastasis through the miR-31-5p/SPRED1 axis, indicating that Huaier granule has the potential to be used as a novel drug for HCC treatment.
