OBJECTIVE: To investigate the clinical efficacy of thoracoscopic minimally invasive surgery with nickel-titanium shape memory alloy wrap bone plate versus rib periosteal internal fixation in patients with multiple rib fractures (MRF) and flail chest. METHODS: A retrospective analysis was performed on 100 patients with MRF and flail chest treated with thoracoscopic minimally invasive surgery and internal fixation with rib fracture preservation between January 2019 and December 2022, including 54 males and 46 females, aged from 20 to 65 years old, with an average age of (38.0±18.0)years old. The duration of the disease ranged from 8 to 21 days. According to the different surgical methods, the patients were divided into control group and study group, with 50 patients in each group. The control group consisted of 23 males and 27 females, with an average age of (38.35±18.05) years old, who underwent rib preservation periosteal internal fixation. In the study group, there were 31 males and 19 females, with an average age of (38.15±17.99) years old, treated with thoracoscopic nickel-titanium shape memory alloy circumferential bone plate. The pulmonary function indices, electrocardiographic monitoring indices, pain severity, levels of inflammatory factors, complications, rehabilitation indices, and therapeutic efficacy were compared between the two groups before and after treatment. RESULTS: All patients were followed up for 6 months. After 3 days of treatment, the heart rate of both groups was (102.43±13.74) beats per minute vs (86.26±8.06) beats per minute, respiratory rate (28.45±3.40) breaths per minute vs (22.05±2.85) breaths per minute, blood oxygen saturation (89.68±3.66)% vs (98.46±4.84)%, rest pain (3.5±0.5) points vs (2.6±0.6) points, movement pain (3.6±0.5) points vs (2.5±0.5) points, and these differences were statistically significant(P<0.05). The levels of Interleukin-6 (IL-6) (102.30±17.00) pg·ml^-1 vs (85.68±21.20) pg·ml^-1 and tumor necrosis factor-alpha (TNF-α)(33.44±4.85) pg·ml^-1 vs (18.14±4.28) pg·ml^-1 in both groups exhibited an increase post-treatment, while the C-reactive protein (CRP) (75.51±10.54) mg·L^-1 vs (60.75±9.84) mg·L^-1 demonstrated a decrease compared to pre-treatment levels. Furthermore, the study group displayed significantly lower levels than the control group (P<0.05). After 10 days of treatment, the peak expiratory flow rate (3.31±0.52) L·s^-1 vs (5.69±0.74) L·s^-1, forced expiratory volume (1.46±0.29) L vs (2.06±0.38) L, and forced vital capacity (2.68±0.95) L vs (4.26±1.05) L of both groups exhibited significant improvements compared to pre-treatment levels. Moreover, the study group demonstrated significantly higher values than the control group (P<0.05). The incidence of postoperative complications in the study group was significantly lower compared to the control group (6 cases vs 14 cases, P<0.05). Additionally, the duration of bone callus formation(9.50±1.40) days and fracture healing (72.20±8.32) days in the study group was significantly shorter compared to the control group(11.35±2.15) days, (93.70±9.90) days (P<0.001). CONCLUSION Compared with traditional rib-preserving internal fixation, patients with MRF and flail chest treated with minimally invasive internal fixation with thoracoscopic nickel-titanium shape memory alloy surround bone plate have better therapeutic effect, because of less surgical trauma, less pain and inflammatory reaction, fewer postoperative pulmonary complications, faster and better recovery of lung function, and thus promote the recovery of patients.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

Objective:This study aims to initially establish a scoring system for comprehensively reflecting the severity of intracranial atherosclerotic lesions and to explore the correlation between this score and atherosclerotic risk factors as well as stroke events.Methods:This study retrospectively analyzed patients who underwent head and neck computer tomography angiography(CTA)examinations and had head MRI examinations within one month before or after the CTA examination from January 2021 to August 2024 in Beijing Hospital.An intracranial atherosclerosis disease score(ICADS)system was constructed based on the degree and number of vascular stenosis.The relationship between ICADS and atherosclerotic risk factors was explored by grouping patients according to the quartile of ICADS.Patients were divided into acute stroke group and non-acute stroke group to compare differences in ICADS and cerebrovascular disease risk factors between the two groups, and to investigate the correlation between stroke events and ICADS.Results:There were statistically significant differences in the proportions of patients with hypertension and diabetes among different ICADS groups.Multiple linear regression analysis showed that hypertension( B=1.17, 95% CI: 0.20-2.14, P<0.05)and diabetes( B=2.75, 95% CI: 1.85-3.64, P<0.001)were risk factors for higher ICADS.The ICADS was higher in the acute stroke group than in the non-acute stroke group(9 vs.6, P<0.001), and a higher ICADS was identified as a risk factor for stroke( OR=1.10, 95% CI: 1.07-1.14, P<0.001). Conclusions:ICADS can comprehensively reflect the severity of intracranial atherosclerotic lesions and is correlated with stroke events, making it useful for clinical screening of high-risk patients for stroke.

Although indigenous malaria has been eliminated in Wuhan since 2013,imported malaria remains a potential threat as an infectious source of local malaria transmission.The epidemiological and clinical characteristics of imported malaria are particularly important in areas where local malaria has been eliminated.This study was aimed at analyzing the epidemiological and clinical characteristics of imported malaria in Wuhan from 2012 to 2019,to provide a basis for further improving the preven-tion and control of imported malaria.Patients in Wuhan diagnosed with imported malaria from January 1,2012,to December 31,2019,were included in this study.A case-control study was con-ducted to analyze the features of patients with severe malaria.Uni-variate and multivariate logistic regression was used to identify risk factors for prolonged hospital length of stay(LOS).Among 229 imported malaria cases,212(92.6％)were in Chinese citizens,and most cases were in men(96.5％).The gender ratio is 28:1,and the age of cases is mainly concertrated between 18 and 50 years old(89.1％).More than 80％of patients were mi-grant workers,and most cases were infections from African countries(92.6％).Plasmodium falciparum(80.8％)was the dominant species.Fifty-three severe malaria cases were identified during the study period.Compared with uncomplicated cases,severe cases tended to occur in patients with no history of malaria(P=0.008),patients infected with Plasmodium falciparum(P=0.009),and patients who were initially misdiagnosed(P＜0.001).The median LOS was 6 days,and the species of infec-tion(Plasmodium falciparum),the use of antimalarial drugs(group B),antipyretic time(longer than 3 days),and the turn-around time of blood smear microscopy(longer than 3 days)were significantly associated with longer LOS(all P＜0.05).Al-though malaria has been eradicated in Wuhan for many years,imported cases continue to pose a threat.Efforts should be made to strengthen malaria knowledge education for outbound personnel.Additionally,medical institutions must enhance diagnosis and treatment capabilities for malaria,and adhere to standardized treatment processes,and the development of drug resistance and occurrence of severe malaria must be prevented.

This study aims to investigate the effect of Linggui Zhugan Decoction(LGZGD) on autophagy in the mouse model of chronic heart failure(CHF) induced by myocardial infarction(MI), as well as the regulatory effect of LGZGD on the hypoxia-inducible factor-1α(HIF-1α)/heme oxygenase-1(HO-1) signaling pathway, based on bioinformatics and animal experiments. The active ingredients and corresponding targets of LGZGD were retrieved from the Traditional Chinese Medicine Systems Pharmacology and Analysis Database, and GEO, GeneCards, and DisGeNET were searched for the disease targets. Cytoscape was used to establish a "drug-component-target" network. The protein-protein interaction(PPI) network analysis was performed on STRING. R language was used for Gene Ontology(GO) and Kyoto Encycloperfia of Genes and Genomes(KEGG) enrichment analyses. Molecular docking was adopted to validate the core targets. The mouse model of MI-induced CHF was established by surgical ligation of the left anterior descending coronary artery. The modeled mice were assigned into the sham, model, low-, medium-, and high-dose(2.34, 4.68, and 9.36 g·kg~(-1), respectively) LGZGD, and captopril(3.25 mg·kg~(-1)) groups. After continuous administration for 6 weeks, a Doppler ultrasound imaging system was used to examine the heart function indicators: left ventricular ejection fraction(LVEF), left ventricular fractional shortening(LVFS), left ventricular end-systolic dimension(LVIDs), and left ventricular end-diastolic dimension(LVIDd). The myocardial tissue was stained with hematoxylin-eosin for the observation of morphological changes. The mRNA levels of microtubule-associated protein 1 light chain 3 beta(LC3B), Beclin1, p62, HIF-1α, and HO-1 in the myocardial tissue were determined by RT-qPCR. The protein levels of LC3B, beclin1, p62, autophagy-related protein 5(ATG5), HIF-1α, and HO-1 were determined by Western blot. The results showed that 103 active components of LGZGD, corresponding to 224 targets, were obtained. A total of 3 485 and 6 165 targets related to MI and CHF, respectively, were retrieved. The GSE16499 dataset obtained 3 263 differentially expressed genes. There were 31 common targets. The top 3 core active components were quercetin, naringenin, and 1-methoxyphaseollidin. The topology analysis results showed that the core targets were MAPK3, HMOX1(HO-1), MYC, ADRB2, PPARD, and HIF1A(HIF-1α). The molecular docking results showed strong binding between the core targets and the main active components of LGZGD. LGZGD significantly improved the heart function and alleviated the pathological changes in the myocardial tissue of mice. Western blot and RT-qPCR results showed that the HIF-1α/HO-1 signaling pathway and autophagy were activated in the model group. LGZGD up-regulated the levels of LC3B, Beclin1, ATG5, HIF-1α, and HO-1 while down-regulating the mRNA and protein levels of p62. In summary, LGZGD can enhance autophagy and improve the heart function in the mouse model of CHF after MI by upregulating the HIF-1α/HO-1 signaling pathway.
