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.

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.

Accurate classification of the acetabular injuries and appropriate treatment plan are great challenges for orthopedic surgeons because of the irregular anatomical structure of the acetabulum and aggregation of important vessels and nerves around it. Letournel-Judet classification system has been widely applied to classify acetabular fractures. However, there are several limitations, including incomplete inclusion of fracture types, difficulty in understanding and insufficient guidance for surgical treatment, etc. Serious complications such as traumatic arthritis are common due to wrong classification and diagnosis and improper selection of surgical strategy, which brings a heavy burden to the society and families. Three-column classification, based on anatomic characteristics, has advantages of containing more fracture types and being easy to understand, etc. To solve the problems existing in the diagnosis and treatment process based on Letournel-Judet classification, achieve accurate diagnosis and treatment of patients with acetabular fractures, and obtain satisfactory prognosis, the Orthopedic Trauma Emergency Center of Third Hospital of Hebei Medical University and the Trauma Orthopedic Branch of the Chinese Orthopedic Association organized experts from relevant fields to formulate the Expert consensus on the accurate diagnosis and treatment of acetabular fractures based on three-column classification ( version 2023) in terms of principles of evidence-based medicine. Based on the three-column classification, 15 recommendations were proposed, covering the diagnosis, treatment, complication prevention and management, etc, so as to provide reference for accurate diagnosis and treatment of acetabular fractures.

Depression is a mental disorder with high morbidity, disability and relapse rates. Ginkgo biloba extract (GBE), a traditional Chinese medicine, has a long history of clinical application in the treatment of cerebral and mental disorders, but the key mechanism remains incompletely understood. Here we showed that GEB exerted anti-depressant effect in mice through regulating gut microbial metabolism. GBE protected against unpredictable mild stress (UMS)-induced despair, anxiety-like and social avoidance behavior in mice without sufficient brain distribution. Fecal microbiome transplantation transmitted, while antibiotic cocktail abrogated the protective effect of GBE. Spatiotemporal bacterial profiling and metabolomics assay revealed a potential involvement of Parasutterella excrementihominis and the bile acid metabolite ursodeoxycholic acid (UDCA) in the effect of GBE. UDCA administration induced depression-like behavior in mice. Together, these findings suggest that GBE acts on gut microbiome-modulated bile acid metabolism to alleviate stress-induced depression.

Infectious bone defect is bone defect with infection or as a result of treatment of bone infection. It requires surgical intervention, and the treatment processes are complex and long, which include bone infection control,bone defect repair and even complex soft tissue reconstructions in some cases. Failure to achieve the goals in any step may lead to the failure of the overall treatment. Therefore, infectious bone defect has been a worldwide challenge in the field of orthopedics. Conventionally, sequestrectomy, bone grafting, bone transport, and systemic/local antibiotic treatment are standard therapies. Radical debridement remains one of the cornerstones for the management of bone infection. However, the scale of debridement and the timing and method of bone defect reconstruction remain controversial. With the clinical application of induced membrane technique, effective infection control and rapid bone reconstruction have been achieved in the management of infectious bone defect. The induced membrane technique has attracted more interests and attention, but the lack of understanding the basic principles of infection control and technical details may hamper the clinical outcomes of induced membrane technique and complications can possibly occur. Therefore, the Chinese Orthopedic Association organized domestic orthopedic experts to formulate An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique ( version 2023) according to the evidence-based method and put forward recommendations on infectious bone defect from the aspects of precise diagnosis, preoperative evaluation, operation procedure, postoperative management and rehabilitation, so as to provide useful references for the treatment of infectious bone defect with induced membrane technique.

This study aims to investigate the intervention effect of the aqueous extract of Epimedium sagittatum Maxim on the mouse model of bleomycin(BLM)-induced pulmonary fibrosis, so as to provide data support for the clinical treatment of pulmonary fibrosis. Ninety male C57BL/6N mice were randomized into normal(n=10), model(BLM, n=20), pirfenidone(PFD, 270 mg·kg~(-1), n=15), and low-, medium-, and high-dose E. sagittatum extract(1.67 g·kg~(-1), n=15; 3.33 g·kg~(-1), n=15; 6.67 g·kg~(-1), n=15) groups. The model of pulmonary fibrosis was established by intratracheal instillation of BLM(5 mg·kg~(-1)) in the other five groups except the normal group, which was treated with an equal amount of normal saline. On the day following the modeling, each group was treated with the corresponding drug by gavage for 21 days. During this period, the survival rate of the mice was counted. After gavage, the lung index was calculated, and the morphology and collagen deposition of the lung tissue were observed by hematoxylin-eosin(HE) and Masson staining, respectively. The levels of reactive oxygen species(ROS) in lung cell suspensions were measured by flow cytometry. The levels of glutathione peroxidase(GSH-Px), total superoxide dismutase(T-SOD), and malondialdehyde(MDA) the in lung tissue were measured. Terminal-deoxynucleoitidyl transferase-mediated nick-end labeling(TUNEL) was employed to examine the apoptosis of lung tissue cells. The content of interleukin-6(IL-6), chemokine C-C motif ligand 2(CCL-2), matrix metalloproteinase-8(MMP-8), transforming growth factor-beta 1(TGF-β1), alpha-smooth muscle actin(α-SMA), E-cadherin, collagen Ⅰ, and fibronectin in the lung tissue was measured by enzyme-linked immunosorbent assay(ELISA). The expression levels of F4/80, Ly-6G, TGF-β1, and collagen Ⅰ in the lung tissue were determined by immunohistochemistry. The mRNA levels of CCL-2, IL-6, and MMP-7 in the lung tissue were determined by qRT-PCR. The content of hydroxyproline(HYP) in the lung tissue was determined by alkaline hydrolysation. The expression of α-SMA and E-cadherin was detected by immunofluorescence, and the protein levels of α-SMA, vimentin, E-cadherin in the lung tissue were determined by Western blot. The results showed the aqueous extract of E. sagittatum increased the survival rate, decreased the lung index, alleviated the pathological injury, collagen deposition, and oxidative stress in the lung tissue, and reduced the apoptotic cells. Furthermore, the aqueous extract of E. sagittatum down-regulated the protein levels of F4/80 and Ly-6G and the mRNA levels of CCL-2, IL-6, and MMP-7 in the lung tissue, reduced the content of IL-6, CCL-2, and MMP-8 in the alveolar lavage fluid. In addition, it lowered the levels of HYP, TGF-β1, α-SMA, collagen Ⅰ, fibronectin, and vimentin, and elevated the levels of E-cadherin in the lung tissue. The aqueous extract of E. sagittatum can inhibit collagen deposition, alleviate oxidative stress, and reduce inflammatory response by regulating the expression of the molecules associated with epithelial-mesenchymal transition, thus alleviating the symptoms of bleomycin-induced pulmonary fibrosis in mice.

The present study investigated the effect of active components of Descurainia sophia on allergic asthma and explored the underlying mechanism. SD male rats were randomly divided into a normal group(NC), a model group(M), a D. sophia decoction group(DS), a D. sophia fatty oil group(FO), a D. sophia flavonoid glycoside group(FG), a D. sophia oligosaccharide group(Oli), and a positive drug dexamethasone group(Y). The allergic asthma model was induced in rats by intraperitoneal injection of ovalbumin(OVA) and aluminum hydroxide gel adjuvant(sensitization) and atomization of OVA solution(excitation). After modeling, asthma-related indicators, tracheal phenol red excretion, inflammatory cell levels in the peripheral blood, lung permeability index(LPI), and oxygenation index(OI) of rats were detected. The pathological changes of lung tissues were observed by HE staining. Enzyme-linked immunosorbent assay(ELISA) was used to detect the content of inflammatory factors immunoglobulin E(IgE), interleukin-4(IL-4), and interferon-γ(IFN-γ) in the bronchoalveolar lavage fluid(BALF) and the content of endothelin-1(ET-1) and angiotensin-converting enzyme(ACE) in lung tissue homogenate. The serum content of nitric oxide(NO) was detected by colorimetry. Western blot was employed to determine the protein expression of Toll-like receptor 4(TLR4), nuclear factor κB-p65(NF-κB-p65), phosphorylated NF-κB-p65(p-NF-κB-p65), myosin light chain kinase(MLCK), vascular endothelial cadherin(VE cadherin), connexin 43, and claudin 5, and the mechanism of active components of D. sophia on allergic asthma was explored. As revealed by the results, the M group showed extensive infiltration of inflammatory cells around the bronchus of the lung tissues of the allergic asthma rats, thickened bronchial wall, severely deformed alveolar structure, increased number of wheezes, the content of IgE, IL-4, ET-1, and ACE, inflammatory cells, and LPI, and reduced latency of asthma, tracheal phenol red excretion, IFN-γ, NO content, and OI. After the intervention of the active components of D. sophia, the DS, FO, FG, Oli, and Y groups showed improved asthma-related indicators, tracheal phenol red excretion, and lung tissue lesions in allergic asthma rats, and the effects in the FO and Oli groups were superior. The content of inflammatory factors in BALF was recovered in the DS, FO, and Y groups and the FG and Oli groups. The number of inflammatory cells in rats was reduced in the DS and FO groups, and the FG, Oli, and Y groups to varying degrees, and the effect in the FO group was superior. DS, FO, Oli, and Y reduced ET-1, ACE, and LPI and increased NO and OI. FG recovered NO, ET-1, ACE, LPI, and OI to improve lung epithelial damage and permeability. Further investigation of inflammation-related TLR4/NF-κB pathways, MLCK, and related skeleton protein levels showed that TLR4, NF-κB-p65, p-NF-κB-p65, and MLCK levels were increased, and VE cadherin, connexin 43, and claudin 5 were reduced in the M group. DS, FO, FG, Oli, and Y could reduce the protein expression related to the TLR4 pathway to varying degrees, and regulate the protein expression of MLCK, VE cadherin, connexin 43, and claudin 5. It is inferred that the active components of D. sophia improve lung permeability in rats with allergic asthma presumedly by regulating the TLR4/NF-κB signaling pathway to improve airway inflammation, mediating MLCK and connexin, and regulating epithelial damage.

Curcuma kwangsiensis root tuber is a widely used genuine medicinal material in Guangxi, with the main active components of terpenoids and curcumins. It has the effects of promoting blood circulation to relieve pain, moving Qi to relieve depression, clearing heart and cooling blood, promoting gallbladder function and anti-icterus. Modern research has proved its functions in liver protection, anti-tumor, anti-oxidation, blood lipid reduction and immunosuppression. Considering the research progress of C. kwangsiensis root tubers and the core concept of quality marker(Q-marker), we predicted the Q-markers of C. kwangsiensis root tubers from plant phylogeny, chemical component specificity, traditional pharmacodynamic properties, new pharmacodynamic uses, chemical component measurability, processing methods, compatibility, and components migrating to blood. Curcumin, curcumol, curcumadiol, curcumenol, curdione, germacrone, and β-elemene may be the possible Q-markers. Based on the predicted Q-markers, the mechanisms of the liver-protecting and anti-tumor activities of C. kwangsiensis root tubers were analyzed. AKT1, IL6, EGFR, and STAT3 were identified as the key targets, and neuroactive ligand-receptor interaction signaling pathway, nitrogen metabolism pathway, cancer pathway, and hepatitis B pathway were the major involved pathways. This review provides a basis for the quality evaluation and product development of C. kwangsiensis root tubers and gives insights into the research on Chinese medicinal materials.

Golgi protein 73 (GP73) is a transmembrane protein on the Golgi apparatus and can be cut and released into the blood. In recent years, an increasing number of clinical studies have shown that the elevated serum GP73 level is closely related to liver diseases. And thus GP73 is expected to be used as a new serum marker for assessing progress of chronic liver diseases. Herein, the clinical application of serum GP73 in chronic hepatitis, liver fibrosis, liver cirrhosis and hepatocellular carcinoma with different etiologies was reviewed based on available literatures; and a research outlook in this field is made.

At T 1-T 5, BIS in group A was (94.16 ± 2.07), (55.34 ± 1.93), (56.61 ± 1.84), (76.29 ± 1.94) and (93.84 ± 2.39) respectively, and it was (94.51 ± 2.25), (52.39 ± 1.58), (52.45 ± 1.94), (73.58 ± 2.19), (93.28 ± 2.52) respectively in group B and (93.97 ± 2.16), (50.57 ± 1.96), (51.60 ± 2.03), (69.51 ± 2.12), (93.57 ± 2.66) respectively in group C. BIS values measured at T 2 ( t = 24.49, 48.60, both P < 0.05), T 3 ( t = 28.34, 54.28, both P < 0.05), and T 4 ( t = 7.61, 15.91, both P < 0.05) in groups B and C were significantly lower than those in group A. BIS measured at T 2 ( t = 24.11, P < 0.05), T 3 ( t = 25.93, P < 0.05), and T 4 ( t = 8.30, P < 0.05) in group C were significantly lower than those in group B. Correlation analysis showed that 95% SEF measured at T 2 ( r = 0.65, P < 0.05), T 3 ( r = 0.68, P < 0.05) and T 4 ( r = 0.49, P < 0.05) were positively correlated with BIS measured at corresponding time points. There were no significant differences in duration of electrical stimulation [(61.25 ± 4.32) seconds, (45.19 ± 3.68) seconds, and (27.54 ± 2.54) seconds, F = 1 434.14, P < 0.05], post-onset inhibition index [(87.68 ± 5.82)%, (81.59 ± 5.35)%, (75.27 ± 4.87)%, F = 87.09, P < 0.05], and average seizure energy index [(5 668.38 ± 1 264.01) μV2, (4 555.61 ± 1 058.96) μV2, (3 642.25 ± 792.68) μV2, F = 59.97, P < 0.05] among the three groups. Duration of electrical stimulation ( t = 36.07, 75.71, both P < 0.05), post-onset inhibition index ( t = 9.15, 18.66, both P < 0.05), and average seizure energy index ( t = 8.49, 15.46, both P < 0.05) in groups B and C were significantly lower than those in group A. Duration of electrical stimulation, post-onset inhibition index and average seizure energy index in group C were significantly lower than those in group B ( t = 39.64, 9.50, 6.97, all P < 0.05). BIS was positively correlated with duration of electrical stimulation ( r = 0.68, P < 0.05), post-onset inhibition index ( r = 0.55, P < 0.05) and average seizure energy index ( r = 0.42, P < 0.05). There were no significant differences in the incidences of headache, myalgia, nausea and vomiting among the three groups ( P > 0.05). Conclusion:95% SEF was positively correlated with BIS in patients with schizophrenia. BIS measured at T 2 was positively correlated with effect of modified electroconvulsive therapy center.
