Background Non-optimal temperatures pose significant threats to public health. Analyzing the association between temperature exposure and the number of emergency cases of acute alcohol intoxication can provide evidence for optimizing emergency resource allocation and response strategies. Objective To analyze the overall impact and lag effects of non-optimal temperatures on the number of 120 emergency calls for acute alcohol intoxication in Wuxi, and to assess the attributable risk, in order to provide empirical evidence for formulating climate-adaptive public health strategies. Methods Call records of acute alcohol intoxication from Wuxi's 120 emergency service, concurrent air pollutant data, and meteorological data (including daily mean temperature) were collected from January 1, 2014 to December 31, 2020. Distributed lag nonlinear modeling was used for time-series analysis, with cross-basis functions to capture the nonlinear relationship and lag effects between temperature and emergency volume. Confounding factors such as long-term trends, humidity, pollutants [ultimately including ozone (O₃) and fine particulate matter (PM_2.5)], day of the week, and holidays were controlled. The maximum lag period was set to 14 days. Single-day lag and cumulative lag effects of extreme temperatures were analyzed, followed by sensitivity analysis. Effects were quantified using relative risk (RR) and 95% confidence intervals (95%CI), and attributable fractions and numbers for different temperature ranges were calculated. Results A total of 10705 emergency cases of acute alcohol intoxication were included during the study period, with males accounting for 89.5% and individuals aged 18–50 years accounting for 83.4%. A non-linear "U-shaped" association was observed between daily mean temperature and the number of emergency calls, with an optimal temperature of 13.3 ℃. The effect of the extreme low temperature (1.88 ℃) was statistically significant from lag1 to lag3 after exposure (P<0.05), with the maximum effect at lag1 (RR=1.063, 95%CI: 1.002, 1.129). The extreme high temperature (32.3 ℃) showed an immediate effect, with maximum effect at lag0 (RR=1.374, 95%CI: 1.248, 1.512). The cumulative effect analysis showed that the risk associated with high temperature was the highest at lag0–3 (RR=2.000, 95%CI: 1.667, 2.399), while the risk associated with low temperature was the highest at lag0–14 (RR=1.462, 95%CI: 1.042, 2.051). The attribution analysis indicated that the mild heat (>24.7–30.8 ℃) and heat (>30.8–33.5 ℃) contributed the largest numbers of attributable cases, with 591 cases (95%CI: 56, 1032) and 190 cases (95%CI: 51, 309), respectively. The corresponding attributable fractions were 5.81% (95%CI: 0.80%, 9.94%) and 1.87% (95%CI: 0.49%, 2.96%), respectively. Conclusion Both extreme high and low temperatures significantly increase the number of 120 emergency calls for acute alcohol intoxication in Wuxi. High temperature exhibit an acute effect, while low temperature show a delayed effect. Mild heat have a significant impact on the emergency burden. It is recommended that emergency departments optimize resource allocation according to climatic characteristics and strengthen emergency responses during extreme weather to reduce alcohol-related health burden.

In the context of continuously deepening medical and health system reforms and comprehensively promoting the "Healthy China" strategy, Henan Provincial People's Hospital has established a regional collaborative and vertically integrated critical care service structure and network. This initiative aims to enhance information empowerment, strengthen regional collaboration, improve the insufficient primary medical services, and ensure timely and effective treatment for critically ill patients. By establishing a comprehensive dispatch service platform for regional collaborative critical care, building a "top-down" remote medical collaboration network, and forming a cross-regional specialty alliance for critical care, the hospital has improved the efficiency of medical services and enhanced regional capabilities for treating critically ill patients. Simultaneously, for critically serious patients and those with complex diseases at primary medical institutions, a one-stop consultation and referral service has been implemented. This service adopts a "three specialists" approach and a multidisciplinary consultation mechanism within the hospital, constructs a multi-dimensional critical care transfer mode integrating air, ground, and the internet, creates a regional collaborative rescue mode, and implements full-cycle treatment for critically serious patients. The comprehensive, flexible, and efficient service pathway for regional collaborative critical care established by this system ensures timely and safe treatment for critically ill patients, promotes the distribution of high-quality medical resources, and effectively addresses issues such as uneven distribution of high-quality medical resources and varying levels of critical care capabilities. It has facilitated the formation of a new tiered diagnosis and treatment order characterized by "first diagnosis at the primary level, two-way referral, separate treatment for acute and chronic diseases, and vertical integration". This approach has enhanced the diagnostic and comprehensive service capabilities of primary medical institutions. Currently, by strengthening information empowerment and sharing, creating a full-process critical care diagnosis and treatment model, providing medical assistance and cultivating primary-level critical care talent, and promoting appropriate technologies, the hospital has gradually overcome challenges such as barriers to information exchange and sharing between hospitals, overloaded critical care teams, high pressure on patient reception and transfer, and limited critical care capabilities at primary medical institutions. This article summarizes the construction and practical application of this regionally coordinated critical care system, aiming to provide a reference for the management of critical care treatment.

Myocardial fibrosis （MF） is a prevalent pathological process in a spectrum of cardiac conditions， including myocardial infarction， hypertensive heart disease， and dilated cardiomyopathy. It is marked by an overabundance of extracellular matrix deposition， diminished myocardial compliance， and impaired cardiac function， which can lead to arrhythmias and sudden cardiac death. The current therapeutic approach primarily aims to suppress the progression of fibrosis， yet the therapeutic outcomes are poor. The pathogenesis of MF involves multiple signaling pathways， including the transforming growth factor-beta （TGF-β）/Smads signaling pathway， nuclear factor-kappa B （NF-κB） signaling pathway， phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， and mitogen-activated protein kinase （MAPK） signaling pathway. Traditional Chinese medicine （TCM） boasts a rich history in the treatment of cardiovascular diseases， offering distinctive benefits such as minimal side effects and high safety， and it has demonstrated promising therapeutic effects in the treatment of MF. In recent years， research has turned its attention to the application of TCM in modulating the signaling pathways associated with MF. It has been demonstrated that TCM can modulate the MF-related signaling pathways to exert anti-inflammatory effects， regulate cellular autophagy， cell proliferation， and apoptosis， reduce myocardial oxidative stress and damage， and inhibit the activation of fibroblasts and collagen synthesis， thereby exhibiting the potential to mitigate or even reverse the progression of MF. Experimental research and clinical observations indicate that TCM formulas such as Yixin Futing decoction， Luhong prescription， Zhilong Huoxue Tongyu capsules， and Kangjian Yixin prescription can effectively ameliorate MF and enhance cardiac function through the multi-component regulation of multiple cellular pathways. Specific TCM constituents， including isoliquiritigenin and astragaloside， have been shown to inhibit the expression of TGF-β₁， thereby disrupting the Smad signaling pathway. Compounds like glycyrrhizic acid and allicin can suppress the NF-κB signaling pathway and curtail collagen synthesis in myocardial cells， and forsythoside can activate the PI3K/Akt signaling pathway， contributing to its anti-fibrotic effects.

BACKGROUND:Intervertebral disc degeneration is caused by damage and degeneration of the nucleus pulposus and annulus fibrosus tissues inside the intervertebral disc,resulting in structural and functional changes of the intervertebral disc.However,there is yet no effective drug treatment for intervertebral disc degeneration. OBJECTIVE:To investigate the inhibitory effect of syringin on intervertebral disc degeneration. METHODS:A total of 10 male Sprague-Dawley rats were selected,and the coccygeal intervertebral disc(Co4/Co5)of each rat was set as model group,Co5/Co6 intervertebral disc as syringin group,and Co6/Co7 intervertebral disc as control group.The control group did not receive any treatment.In the model group and syringin group,a miniature puncture needle was used to puncture the annulus fibrosus to establish an intervertebral disc degeneration model.Immediately after modeling,2.5 μL of normal saline and syringin solution(5 μmol/L)were given in the model and syringin groups,respectively.Four weeks after injection,the samples were taken.The degree of intervertebral disc degeneration in rats was observed by hematoxylin-eosin and safranine O-fast green staining.The expressions of type Ⅱ collagen,aggrecan and matrix metalloproteinases 3 and 13 in intervertebral disc tissue were analyzed by immunohistochemical staining. RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that in the model group,the height of intervertebral disc decreased,the cartilage endplate became thinner and cracked,the fibrous ring structure was disordered and cracked,and the nucleus pulposus disappeared;in the syringin group,the height of intervertebral disc was normal or slightly lower than that in the control group,the degree of cartilage endplate degeneration was lighter than that in the model group,the fiber circle permutation was relatively regular with no cracks,and the nucleus pulposus was partially shrunk.Safranine O-fast green staining showed that in the model group,the cartilage endplate of the intervertebral disc was defective and the calcified layer of cartilage became thinner,showing obvious degeneration.The structure and morphology of intervertebral disc cartilage endplate in the syringin group recovered to some extent.Immunohistochemical staining showed that,compared with the control group,the expressions of type Ⅱ collagen and aggrecan in the intervertebral disc cartilage were decreased in the model group(P<0.000 1),while the expressions of matrix metalloproteinases 3 and 13 increased(P<0.000 1).Compared with the model group,the expressions of type Ⅱ collagen and aggrecan in the intervertebral disc cartilage tissue were increased in the syringin group(P<0.001,P<0.000 1),while the expressions of matrix metalloproteinases 3 and 13 decreased(P<0.001,P<0.000 1).These results showed that syringin could improve the structure and function of intervertebral disc by inhibiting the expression of matrix metalloproteinases 3 and 13 and increasing the expression of type Ⅱ collagen and aggrecan,thus preventing and slowing down the procession of intervertebral disc degeneration.

Literature analysis,expert consultation,case analysis and other methods were used to establish a public hospital specialty operation evaluation system suitable for high-quality development,including 2 first-level indicators of medical ability and economic operation and 13 second-level indicators.Urology surgery in the pilot hospital was taken as an example to carry out surgical operation effect evaluation.To strengthen the evaluation of public hospital specialized operation,it should pay attention to the evaluation of medical capacity,strengthen the cooperation of functional departments,and improve the supporting policies of operation,for better promoting the development of high-quality operation of hospitals.

Objective:To explore the diagnosis and treatment of lymphoepithelioma-like intrahepatic cholangiocarcinoma(LEL-ICC).Methods:The retrospective and descriptive study was conducted. The data of 7 patients with pathological diagnosis of LEL-ICC after hepatectomy who were treated in Lishui Central Hospital in Zhejiang Province from December 1, 2009 to January 30, 2024 were collected. There were 2 males and 5 females. The age range was from 40 to 64 years old, with a median age of 52 years old. All 7 patients showed no obvious clinical symptoms.We analysed the imaging manifestations, pathological features, treatmentsand prognoses of patients.Postoperative follow-upswere conducted via telephone, with a focus on whether the patient had relapsed. The deadline was February 20, 2024.Results:Five cases underwent ultrasound examination, of which 4 cases showed hypoechogenicity and 1 case showed hyperechogenicity. 7 cases underwent MRI examination, showing low signal on T1WI, high signal on T2WI, and high signal on diffusion-weighted imaging. 2 cases had type A enhancement, 2 cases had type B enhancement, and 3 cases had type C enhancement. All 7 cases received surgical treatment, 2 cases were received prophylactic transarterial chemoembolization (TACE) after surgery, and 3 cases were received systemic chemotherapy after surgery; All 7 cases underwent postoperative follow-up, with a follow-up time of 1-166 months and a median follow-up time of 56 months. One case developed hilar and retroperitoneal lymph node metastasis after surgery for 6 months, and underwent surgical treatment. After surgery, chemotherapy was performed. 25 months later, right adrenal gland metastasis reappeared, and after combined treatment, the metastatic lesion was reduced and the patient received surgical treatment and chemotherapy, and there is currently no recurrence. The remaining 6 cases showed no recurrence.Conclusions:LEL-ICC lacks specific clinical symptoms and imaging manifestations, diagnosis relies on histopathological and immunohistochemical examinations. Comprehensive treatment with surgical intervention as the main approach can lead to better prognosis for patients.

Objective:To explore the clinical manifestations, diagnosis and treatment methods, and prognosis of hepatic portal venous gas (HPVG).Methods:Retrospective case analysis was used in the case data of 7 patients with HPVG, who were treated in Lishui Central Hospital from January 2017 to July 2024, including 5 males and 2 females. Age ranged from 46 to 90 years, with an average age of 69 years. Abdominal pain was the first manifestation in 6 cases, and septic shock occurred in 2 cases. The initial symptoms, primary diseases, comorbidities, laboratory results, imaging examinations, treatment plans, and prognosis were analyzed. Prognostic follow-up was conducted by telephone, with the focus on whether the patient had experienced HPVG recurrence and postoperative complications. The deadline for follow-up was July 31, 2024.Results:All patients had elevated white blood cells and C-reactive protein (CRP), and prothrombin time was prolonged in 4 patients. pH and base excess decreased in 4 cases, and lactic acid increased in 5 cases. Alanine aminotransferase increased in 2 cases, and total bilirubin increased in 3 cases. Blood culture was positive in 3 cases. Contrast-enhanced abdominal CT showed clear gas shadows in the portal vein and its branches in all 7 cases, which were confined to the left liver in 4 cases and distributed in both sides of the liver in 3 cases. The primary diseases were intestinal obstruction and necrosis in 4 cases, intestinal perforation and necrosis in 1 case, inflammatory bowel disease in 1 case, and acute pancreatitis in 1 case. Five patients were complicated with hypertension, diabetes and other diseases. Two patients received surgical treatment, and the average time from surgery to diagnosis was 6.8 h. Five cases received conservative treatment, 2 cases were cured and 3 cases died, with an average time from onset to death of 21.2 h.Conclusions:Contrast-enhanced abdominal CT should be the preferred method for the diagnosis of HPVG. The primary disease and its severity should be fully evaluated in the treatment of HPVG. Patients with intestinal necrosis should undergo laparotomy as soon as possible, and enterostomy should be performed during the operation. Clinicians should strengthen the awareness of HPVG in order to improve the prognosis of patients.

Gastric cancer(GC)is one of the most common gastrointestinal tumors.As a newly discovered type of non-coding RNAs,transfer RNA(tRNA)-derived small RNAs(tsRNAs)play a dual biological role in cancer.Our previous studies have demonstrated the potential of tRF-23-Q99P9P9NDD as a diagnostic and prognostic biomarker for GC.In this work,we confirmed for the first time that tRF-23-Q99P9P9NDD can promote the proliferation,migration,and invasion of GC cells in vitro.The dual luciferase reporter gene assay confirmed that tRF-23-Q99P9P9NDD could bind to the 3'untranslated region(UTR)site of acyl-coenzyme A dehydrogenase short/branched chain(ACADSB).In addition,ACADSB could rescue the effect of tRF-23-Q99P9P9NDD on GC cells.Next,we used Gene Ontology(GO),the Kyoto Encyclopedia of Genes and Genomes(KEGG),and Gene Set Enrichment Analysis(GSEA)to find that downregulated ACADSB in GC may promote lipid accumulation by inhibiting fatty acid catabolism and ferroptosis.Finally,we verified the correlation between ACADSB and 12 ferroptosis genes at the transcriptional level,as well as the changes in reactive oxygen species(ROS)levels by flow cytometry.In summary,this study proposes that tRF-23-Q99P9P9NDD may affect GC lipid metabolism and ferroptosis by targeting ACADSB,thereby promoting GC progression.It provides a theoretical basis for the diagnostic and prognostic monitoring value of GC and opens up new possibilities for treatment.

OBJECTIVE: To explore the effects of veno-venous extra corporeal carbon dioxide removal (V-V ECCO₂R) on local mechanical power and gas distribution in the lungs of patients with mild to moderate acute respiratory distress syndrome (ARDS) receiving non-invasive ventilation. METHODS: Retrospective research methods were conducted. Sixty patients with mild to moderate ARDS complicated with renal insufficiency who were transferred to the respiratory intensive care unit (RICU) through the 96195 platform critical care transport green channel from January 2018 to January 2020 at the collaborative hospitals of Henan Provincial People's Hospital were enrolled. According to different treatment methods, they were divided into a conventional treatment group and an ECCO₂R group, with 30 patients in each group. Both groups received standard treatments including primary disease treatment, airway management, and non-invasive ventilation. The conventional treatment group received bedside continuous renal replacement therapy (CRRT), and the ECCO₂R group received V-V ECCO₂R treatment. General information of patient such as gender, age, cause of disease, and acute physiology and chronic health evaluation II (APACHE II) were recorded; arterial blood gas analysis was performed before treatment and at 12 hours and 24 hours during treatment, recording arterial partial pressure of oxygen (PaO₂), arterial partial pressure of carbon dioxide (PaCO₂), and oxygenation index (PaO₂/FiO₂). Respiratory mechanics parameters [tidal volume, respiratory rate, maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP)] were recorded, and the rapid shallow breathing index (RSBI) was calculated; electrical impedance tomography (EIT) was used to measure regional of interest (ROI) values in different lung areas at 12 hours and 24 hours of treatment, and the pulmonary mechanical energy was calculated. RESULTS: The arterial blood gas analysis indicators, respiratory mechanics parameters, and pulmonary mechanical energy of patients in the conventional treatment group and ECCO₂R group improved significantly after 24 hours of treatment compared to 12 hours of treatment (all P < 0.05). The levels of PaCO₂, RSBI, total mechanical power, and non-dependent zone mechanical power in the ECCO₂R group were significantly lower than those in the conventional treatment group at both 12 hours and 24 hours during the treatment [PaCO₂ (mmHg, 1 mmHg ≈ 0.133 kPa): 44.03±2.96 vs. 49.96±2.50 at 12 hours, 41.65±3.21 vs. 48.53±2.33 at 24 hours; RSBI (times×min^-1×L^-1): 88.67±4.05 vs. 92.35±4.03 at 12 hours, 77.66±4.64 vs. 90.98±4.21 at 24 hours; total mechanical power (mJ): 10.40±1.15 vs. 12.93±1.68 at 12 hours, 11.13±1.18 vs. 14.05±1.69 at 24 hours; non-dependent zone mechanical power (mJ): 7.15±0.84 vs. 7.98±0.75 at 12 hours, 7.77±0.93 vs. 9.13±1.10 at 24 hours], and MEP and MIP in the ECCO₂R group were significantly higher than those in the conventional treatment group at both 12 hours and 24 hours during the treatment [MEP (cmH₂O, 1 cmH₂O ≈ 0.098 kPa): 89.88±5.04 vs. 86.09±5.57 at 12 hours, 96.57±2.59 vs. 88.66±2.98 at 24 hours; MIP (cmH₂O): 47.64±2.82 vs. 41.93±2.44 at 12 hours, 60.11±6.53 vs. 43.63±2.80 at 24 hours], the differences were statistically significant (all P < 0.05). CONCLUSIONS V-V ECCO₂R combined with non-invasive ventilation can effectively reduce the regional tidal volume, mechanical power, and respiratory rate in the non-gravitational dependent zones of patients with mild to moderate ARDS, and improve respiratory distress and oxygenation status.
