BACKGROUND: Biomarkers-based prediction of long-term risk of acute coronary syndrome (ACS) is scarce. We aim to develop a risk score integrating clinical routine information (C) and plasma biomarkers (B) for predicting long-term risk of ACS patients. METHODS: We included 2729 ACS patients from the OCEA (Observation of cardiovascular events in ACS patients). The earlier admitted 1910 patients were enrolled as development cohort; and the subsequently admitted 819 subjects were treated as validation cohort. We investigated 10-year risk of cardiovascular (CV) death, myocardial infarction (MI) and all cause death in these patients. Potential variables contributing to risk of clinical events were assessed using Cox regression models and a score was derived using main part of these variables. RESULTS: During 16,110 person-years of follow-up, there were 238 CV death/MI in the development cohort. The 7 most important predictors including in the final model were NT-proBNP, D-dimer, GDF-15, peripheral artery disease (PAD), Fibrinogen, ST-segment elevated MI (STEMI), left ventricular ejection fraction (LVEF), termed as CB-ACS score. C-index of the score for predication of cardiovascular events was 0.79 (95% CI: 0.76-0.82) in development cohort and 0.77 (95% CI: 0.76-0.78) in the validation cohort (5832 person-years of follow-up), which outperformed GRACE 2.0 and ABC-ACS risk score. The CB-ACS score was also well calibrated in development and validation cohort (Greenwood-Nam-D'Agostino: P = 0.70 and P = 0.07, respectively). CONCLUSIONS CB-ACS risk score provides a useful tool for long-term prediction of CV events in patients with ACS. This model outperforms GRACE 2.0 and ABC-ACS ischemic risk score.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To investigate the cosmetic effect of biplane fixed technique for double-eyelid plasty.Methods:From September 2019 to June 2021, 80 patients, including 6 males and 74 females, aged 18-45 years with an average age of 31 years, were treated with single eyelid cosmetic surgery at the Medical Aesthetics Department of Northern Jiangsu People′s Hospital Affiliated to Yangzhou University. All the cases were performed by the " biplane fixed technique", and the key point of the surgery was to fix the orbicularis labii muscle in biplane (hard fixation plus soft suspension). A questionnaire survey was conducted and preoperative and postoperative photos were collected for statistical analysis to evaluate postoperative outcomes. The patients were follow up for 6-12 months after surgery, and the incidence of postoperative complications were calculated.Results:The incisions of 80 patients all healed by first intention. 79 patients were satisfied, accounting for 98.75%. Physicians evaluated 78 cases as satisfactory, accounting for 97.50%. The Vancouver Scar Scale score was 2.31±1.80, and the Edema and Eczema Visual Simulation Scale score was 3.58±2.15. After surgery, there were no significant abnormalities when eyes opening or closing, and the shape of the double eyelid remained intact without shedding. The scar on the closed eye incision was mild and there was no obvious depression.Conclusions:The " biplane fixed technique" blepharoplasty can form a firm double eyelid line, which is not easy to fall off and has slight scars. The postoperative effect is stable and worthy of clinical application.

AIM: To investigate the differences in visual recovery, corneal astigmatism, and rotation stability of Toric intraocular lens(TIOL)implantation in cataract patients with different axial lengths.METHODS: Retrospective analysis. A total of 132 patients(132 eyes)with age-related cataract and corneal astigmatism who underwent phacoemulsification cataract extraction combined with TIOL implantation in our hospital's ophthalmology department from February 2021 to September 2022 were selected. They were divided into two groups based on the axial length: the group with axial length ≤24mm(79 cases, 79 eyes)and the group with axial length >24mm(53 cases, 53 eyes). Compare the best corrected distance visual acuity(BCDVA), corneal astigmatism, and TIOL rotation between the two groups of patients at 3mo after surgery.RESULT: After 3mo of surgery, both groups of patients had improved BCDVA and significantly decreased corneal astigmatism compared to those before surgery(P<0.001). However, there was no difference in BCDVA and corneal astigmatism between the two groups(P>0.05), and there was no significant difference in TIOL rotation between the two groups [(5.24±3.72)° vs.(6.36±4.21)°, P=0.110].CONCLUSION: There is no significant difference in visual recovery, corneal astigmatism, and TIOL rotational stability after TIOL implantation in cataract patients with different axial lengths.

In acute lung injury, two subsets of lung macrophages exist in the alveoli: tissue-resident alveolar macrophages (AMs) and monocyte-derived alveolar macrophages (MDMs).However, it is unclear whether these 2 subsets of macrophages have different functions and characteristics during the recovery phase. RNA-sequencing of AMs and MDMs from the recovery period of LPS-induced lung injury mice revealed their differences in proliferation, cell death, phagocytosis, inflammation and tissue repair. Using flow cytometry, we found that AMs showed a higher ability to proliferate, whereas MDMs expressed a larger amount of cell death. We also compared the ability of phagocytosing apoptotic cells and activating adaptive immunity and found that AMs have a stronger ability to phagocytose, while MDMs are the cells that activate lymphocytes during the resolving phase. By testing surface markers, we found that MDMs were more prone to the M1 phenotype, but expressed a higher level of pro-repairing genes. Finally, analysis of a publicly available set of single-cell RNA-sequencing data on bronchoalveolar lavage cells from patients with SARS-CoV-2 infection validated the double-sided role of MDMs. Blockade of inflammatory MDM recruitment using CCR2 −/− mice effectively attenuates lung injury. Therefore, AMs and MDMs exhibited large differences during recovery. AMs are long-lived M2-like tissue-resident macrophages that have a strong ability to proliferate and phagocytose. MDMs are a paradoxical group of macrophages that promote the repair of tissue damage despite being strongly pro-inflammatory early in infection, and they may undergo cell death as inflammation fades. Preventing the massive recruitment of inflammatory MDMs or promoting their transition to pro-repairing phenotype may be a new direction for the treatment of acute lung injury.

Xuanfu Daizhe Decoction, first seen in Zhang Zhongjing's Treatise on Cold Damage Diseases, was composed of seven medicinal materials: Inulae Flos, Glycyrrhizae Radix, Ginseng Radix, Zingiberis Rhizoma Recens, Haematitum, Pinelliae Rhizoma and Jujubae Fructus. It was used to treat gastric fullness and hardness and belching due to the wrong treatment of typhoid fever and sweating. With detailed records and description in ancient medical books, Xuanfu Daizhe Decoction was widely adopted in clinical practice by physicians of later generations, which expanded its main therapeutic functions. By comprehensive collation of ancient and modern literature on Xuanfu Daizhe Decoction, this paper systematically explored the historical evolution of the prescription from the source, composition, dosage, processing, clinical application, function interpretation and decocting method. It was found that the composition and processing method of the prescription in the past dynasties were relatively consistent, and there was a gradual decrease in dosage in clinical application. In ancient times, Xuanfu Daizhe Decoction was mainly used to treat nausea, vomiting, hiccups, constipation, etc., while modern clinicians mainly used it for digestive diseases such as reflux esophagitis and gastritis. Through the analysis and textual research, the composition, dosage, processing, function evolution and decocting method of this prescription were determined, which provided reference for the research and development of compound preparations of Xuanfu Daizhe Decoction.

OBJECTIVE: Through showing the full picture of double-arm controlled clinical research and systematic review evidence in the field of orally administrated Chinese herbal medicine (CHM) for treatment of lung cancer, to provide a reference for future clinical research and to indicate a direction for future systematic reviews. METHODS: A comprehensive search of clinical controlled studies was performed regarding orally administered CHM treatment for lung cancer published from January 1970 to September 2020. The language was restricted to Chinese and English. Relevant data were extracted, the quality of systematic reviews was evaluated, and the research evidence was visually displayed. RESULTS: Randomized controlled trials were the most common type of research design. The research sample sizes were typically small. Oral CHM showed certain curative advantages in treating lung cancer. The key stages in oral CHM intervention for lung cancer are chemotherapy, radiotherapy, and late palliative treatment. The advantageous outcomes of oral CHM treatment of lung cancer are the short-term efficacy, quality of life, and adverse reactions. The perioperative stage, overall survival, pharmacoeconomic evaluation, and Chinese medicine decoctions are weak research areas. CONCLUSIONS CHM has staged and therapeutic advantages in treating lung cancer. The overall methodological quality is poor, and the level of evidence requires improvement. It is necessary to carry out large-scale, standardized, and higher-quality research in the superior and weak areas of CHM treatment of lung cancer.

ObjectiveTo explore the effect and mechanism of Xiaojindan extract （XJD） on macrophage polarization. MethodLipopolysaccharide （LPS） and interleukin-4 （IL-4） were used to induce M1 and M2 polarization of RAW264.7 cells. The influence of 10-80 mg·L^-1 XJD on cell proliferation was detected by Cell Counting Kit-8 （CCK-8） assay. Nitric oxide （NO） and interleukin-6 （IL-6） release was explored by Griess assay and enzyme-linked immunosorbent assay （ELISA）， respectively. The mRNA expression of M1 and M2 macrophage markers was measured by real-time quantitative polymerase chain reaction （Real-time PCR）， and the CD206⁺ expression was determined by flow cytometry. The activation of phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） pathway was analyzed by western blot. Result10-80 mg·L^-1 XJD showed no marked cytotoxicity in LPS （0.5 mg·L^-1）- or IL-4 （20 μg·L^-1）-induced RAW264.7 cells. Compared with the control group， LPS significantly promoted the expression of M1 macrophage markers （P<0.01）， including increased NO and IL-6 release （P<0.01） and upregulated mRNA expression of interleukin-1β （IL-1β）， inducible nitric oxide synthase （iNOS）， cyclooxygenase-2 （COX-2） and tumor necrosis factor-α （TNF-α） （P<0.01）. Compared with LPS-induced group， 20-80 mg·L^-1 XJD decreased the release of NO and IL-6 in a dose-dependent manner （P<0.01）， and similarly 10-80 mg·L^-1 XJD suppressed the mRNA expression of IL-1β， iNOS， COX-2 and TNF-α （P<0.01）. Compared with the control group， IL-4 obviously increased the expression of M2 macrophage markers （P<0.01）， including increased CD206⁺ cell population and upregulated mRNA expression of arginine-1 （Arg-1）， interleukin-10 （IL-10）， interleukin-13 （IL-13） and transforming growth factor-β₁ （TGF-β₁）. Compared with IL-4-induced group， 10-80 mg·L^-1 XJD dose-dependently decreased CD206⁺ cell population （P<0.01） and inhibited the mRNA expression of Arg-1， IL-10， IL-13 and TGF-β₁ （P<0.01）. Western blot showed that XJD significantly downregulated the activation of PI3K/Akt pathway as compared to LPS- and IL-4-induced groups （P<0.05， P<0.01）. ConclusionXJD significantly inhibited the macrophage polarization in the LPS- and IL-4-induced RAW264.7 cells by targeting PI3K/Akt pathway.
