OBJECTIVE: The self-defined multidisciplinary (endocrinology, vascular surgery, and orthopedics) scoring system (EMO scoring system for short) was designed. The feasibility of the EMO scoring system to guide the proximal tibial transverse transport (TTT) for diabetic foot wounds was preliminarily explored. METHODS: Based on the current commonly used clinical criteria for diabetic foot judgment, expert consensus, guidelines, and related research progress in the treatment of diabetic foot wounds, combined with clinical experience, a set of EMO scoring systems including endocrinology, vascular surgery, and orthopedics was formulated. The criteria for selecting conservative treatment, TTT after baseline improvement, and TTT based on scoring results was proposed. A total of 56 patients with diabetic foot wounds who were admitted between September 2017 and July 2022 and met the selection criteria was taken as the study subjects. Among them, 28 patients were treated with TTT and 28 patients were treated conservatively. The patients were graded according to the EMO scoring system, the corresponding treatment methods were selected, and the actual treatment methods and results of the patients were compared. RESULTS: The EMO scoring system was formed through literature retrieval and clinical experiences. The system included three criteria, namely endocrinology (E), macrovascular disease (M), and orthopedics (O), which were divided into multiple subtypes according to the relevant evaluation items, and finally the diabetic foot wound was divided into 8 types, which correspondingly selected TTT, TTT after baseline improvement, and conservative treatment. All 56 patients were followed up 12 months after treatment. Among them, the wound healing rate of the TTT group was 85.71% (24/28), which was higher than that of the conservative treatment group [53.57% (15/28)]. At 12 week after treatment, CT angiography showed that there were more small blood vessels in the wound and ipsilateral limb in TTT group than in the conservative treatment group. Based on the EMO scoring system, 14 of the 56 patients needed conservative treatment, 29 patients needed TTT, and 13 patients needed TTT after baseline improvement. Compared with the clinical data of the patients, the wound healing rate of the patients judged to be TTT was 75.86% (22/29), of which 21 cases were actually treated with TTT, and the healing rate was 90.48%; 8 patients were treated conservatively, and the healing rate was 37.50%. The wound healing rate of the patients judged to be conservative treatment was 92.86% (13/14), of which 1 case was actually treated with TTT, and the healing rate was 100%; 13 cases were treated conservatively, and the healing rate was 92.31%; 1 case experienced minor amputation. The wound healing rate of the patients judged to TTT after baseline improvement was only 30.77% (4/13), of which 6 cases were actually treated with TTT, and the healing rate was 66.67%; 7 cases were treated conservatively, and the healing rate was 0. CONCLUSION EMO scoring system can comprehensively evaluate the diabetic foot wounds, and make personalized judgment on whether TTT treatment is feasible, so as to improve the level of diabetic foot wound treatment and the prognosis of patients.

OBJECTIVE: To construct an integrated management model for early screening and diagnosis of PCa based on the Innovative Care for Chronic Conditions Framework (ICCC) and the 1+1 contract-based tiered diagnosis and treatment system (TDTS) in China. METHODS: Based on the 1+1 contract-based TDTS platform, we conducted PCa screening for the male residents aged 60 years and above during health check-ups in Pujin Community Health Center from January 1, 2023 to December 31, 2023. For those with abnormal total prostate-specific antigen (tPSA) ≥ 4 μg/L, we promptly referred them to higher-level hospitals for further diagnosis and treatment via the two-way referral green channel platform and information sharing service using the 1+1 contract model. We further analyzed the relevant data on screening and diagnosis. RESULTS: A total of 4 080 males aged 71.39±5.059 years received PCa screening from January to December 2023. PSA screening was performed in 43.96% of the male residents, revealing 654 cases of PSA abnormality, with a PSA positivity rate of 16.03%, which was higher than that found in the previous large-scale PCa screenings in other regions of China. Among the males with PSA abnormality, 292 (44.65%) expressed their willingness for medical referral, while the others did not seek further medical attention for reasons of being asymptomatic, low awareness of the disease, no accompany for medical visits, and concerns about further costs of diagnosis and treatment. Prostate biopsy was recommended to 154 cases after further examinations, which was accepted by 92 (59.74%). Fifty-eight cases were diagnosed with Pa, and thedetection rate reached 63.04%. CONCLUSION The integrated management model for PSA examination-based early screening and diagnosis of PCa using the 1+1 contract-based TDTS platform is plays a significant role in enhancing people's awareness and knowledge of PCa and improving the early detection rate of the malignancy.

Colorectal cancer (CRC) poses a severe global health challenge with high incidence and mortality rates. USP37 has been identified as the bona fide deubiquitinase of SND1, playing a critical role in stabilizing SND1, thereby augmenting its oncogenic potential. The interaction between USP37 and SND1 was confirmed through extensive proteomics, ubiquitinomics, and interactomics, underscoring their synergistic effects on CRC proliferation and metastasis. Additionally, CDK1 has emerged as a pivotal regulator of USP37, phosphorylating it at threonine 631 rather than serine 628, enhancing its deubiquitinase activity, and consequently stabilizing SND1 to drive CRC malignancy further. Histological analyses of human CRC samples linked the upregulation of CDK1 and USP37 with increased SND1 levels and poor patient prognosis. High-throughput virtual screening and subsequent experimental validation identified Dacarbazine as a pharmacological inhibitor of USP37, and its inhibition disrupted SND1 stability, hindering CRC cell proliferation and metastasis. This study reveals a novel and promising molecular mechanism driving CRC progression through the CDK1-USP37-SND1 axis, highlighting the clinical importance of targeting this pathway to improve patient outcomes.

Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 molar ratio, driven by electrostatic interactions, hydrophobic interactions, and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective:To explore the effects of neutrophilic granule protein (NGP) on the expression of lipocalin 2 (LCN2) in inflammatory macrophages and its mechanism.Methods:NGP-high-expressed RAW264.7 cells (NGP/RAW cells) and negative control RAW264.7 cells (NC/RAW cells) were cultured in vitro. Primary peritoneal macrophages of NGP-high-expressed mice and wild-type C57BL/6 mice were extracted, then cultured in vitro. The cell inflammatory model was established by stimulating with 10 mg/L lipopolysaccharide (LPS, LPS group), and the phosphate buffer solution (PBS) control group was set up. Enzyme-linked immunosorbent assay (ELISA) was used to detect the level of LCN2 in different types of cells. The protein expression of phosphorylated signal transduction and activator of transcription 1 (p-STAT1) was detected with Western blotting. Other NGP/RAW cells and NC/RAW cells were treated with 10 mg/L LPS, 5 mg/L STAT1 pathway inhibitor (fludarabine)+10 mg/L LPS, respectively. The PBS control group was set up. ELISA was used to detect the level of LCN2. Results:In different types of cells, the levels of LCN2 were increased significantly after LPS stimulation in the LPS group as compared with those in the PBS control group, and peaked at 24 hours (μmol/L: 25.61±1.02 vs. 0.46±0.02 in NC/RAW cells, 74.51±2.14 vs. 0.25±0.04 in NGP/RAW cells, 10.13±0.22 vs. 0.01±0.01 in primary macrophages of wild-type C57BL/6 mice, 28.35±0.61 vs. 0.08±0.01 in primary macrophages of NGP-high-expressed mice, all P < 0.05), indicating that the expression of LCN2 in macrophages altered during inflammation reaction. The level of LCN2 in NGP/RAW cells was found significantly increased at different time points after LPS stimulation comparing with that in NC/RAW cells (μmol/L: 8.32±0.22 vs. 3.12±0.11 at 6 hours, 23.12±0.86 vs. 8.12±0.32 at 12 hours, 74.51±2.14 vs. 25.61±1.02 at 24 hours, all P < 0.05), along with the expression of p-STAT1 was significantly up-regulated. The level of LCN2 in the primary macrophages of NGP-high-expressed mice was also significantly increased at 24 hours after LPS stimulation comparing with that in the primary macrophages of wild-type C57BL/6 mice (μmol/L: 28.35±0.61 vs. 10.13±0.22, P < 0.05). However, after pretreated with STAT1 pathway inhibitors, the production of LCN2 in NGP/RAW cells was decreased significantly comparing with that in the LPS group (μmol/L: 6.81±0.19 vs. 22.54±0.58, P < 0.05). But the inhibitors had no significant effect on LCN2 production in NC/RAW cells showing no significant difference as compared with LPS group (μmol/L: 8.04±0.20 vs. 7.86±0.15, P > 0.05), indicating that NGP could up-regulate the expression of LCN2 in macrophages stimulated by LPS by promoting STAT1 activation. Conclusion:NGP could positively regulate LCN2 expression in inflammatory macrophages by activating STAT1 pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To compare the characteristics of gait disorders between patients with idiopathic normal pressure hydrocephalus(iNPH)and Parkinson's disease(PD)patients.Methods:General clinical data and gait assessment results of 16 iNPH patients, 20 PD patients, and 23 healthy adults seeking treatment at Tianjin Huanhu Hospital between January 2020 and December 2020 were retrospectively analyzed.Gait analysis was conducted using the Mobility Lab? system with APDM Opal sensors from the US.Results:The 16 patients in the iNPH group had a mean age of(68.81±8.73), the 20 patients in the PD group had a mean age of(65.05±10.15), and the 23 adults in the control group had a mean age of(59.96±6.20).There was no significant difference in age between the iNPH group and the PD group( P>0.05).However, the iNPH group was older than the healthy control group( t=3.71, P<0.05).The disease duration of the iNPH group was(22.94±23.19)months, which was shorter than(92.60±53.70)months in the PD group( t=5.23, P<0.05).The mini-mental state examination(MMSE)score(17.13±7.08)and the Montreal Cognitive Assessment(MoCA)score(11.75±5.43)of the iNPH group were significantly lower than those in the PD group[(24.17±4.73), t=3.45, P<0.05、(21.29±5.82), t=4.86, P<0.05]and the control group[(26.70±1.61), t=5.31, P<0.05、(22.78±3.30), t=7.89, P<0.05].Compared with the PD group, the iNPH group had a significantly lower foot clearance[right: (1.65±0.76)cm vs.(2.56±1.30)cm]and smaller bilateral toe-off angles[left: (20.59±6.11)° vs.(28.43±6.36)°; right: (20.78±6.88)° vs.(28.12±7.49)°, t=3.74、3.02, respectively, all P<0.05].There were statistically significant differences in all gait parameters in iNPH patients compared with the control group( P<0.05). Conclusions:iNPH patients exhibit clear gait disturbance, which is more prominent than in PD patients.The wearable gait analysis system can accurately assess gait disorders in iNPH patients, and can be applied to gait assessment and the development of rehabilitation plans.
