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.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective To compare the clinical outcomes of using elastic intramedullary nail and plate to fix fibular frac-ture.Methods The 60 patients with tibiofibular fractures admitted from January 2015 to December 2022 were divided into two groups:intramedullary nail group and plate group,30 cases each,intramedullary nail group was treated with elastic in-tramedullary nail fixation group,plate group was treated with steel plate and screw fixation group.Intramedullary nail group,there were 18 males and 12 females,aged from 22 to 75 years old with an average of(39.4±9.8)years old,including 24 cases of traffic accidents injury,6 cases of falling injury,23 cases of closed fractures,7 cases of open fractures.Steel plate group,there were 15 males and 15 females,aged from 24 to 78 years old with an average of(38.6±10.2)years old.The 22 cases were injured by traffic accident,8 cases were injured by falling.The 24 cases were closed fractures and 6 cases were open fractures.The operation time,intraoperative bleeding,American Orthopedic Foot and Ankle Society(AOFAS)ankle and hind foot scores,clinical healing time of fibula and the incidence of wound complications were compared between the two groups.Re-sults The patients in both groups were followed up for 6 to 21 months,with an average of(14.0±2.8)months.Compared with plate group,intramedullary nail group had shorter operative time,less bleeding,shorter clinical healing time of fibula,and low-er infection rate of incision,and the difference was statistically significant(P＜0.05).There were 2 cases of delayed healing in intramedullary nail group,1 case of nonunion in plate group,and 2 cases of delayed healing in plate group,and there was no statistically significant difference between the two groups(P＞0.05).In the last follow-up,according to the AOFAS scoring standard,the ankle function in intramedullary nail group was excellent in 17 cases,good in 12 cases,fair in 1 case,with an av-erage of(88.33±4.57)points,while in plate group,excellent in 16 cases,good in 10 cases,fair in 4 cases,with an average of(87.00±4.14)points;There was no statistical difference between the two groups(P＞0.05).Conclusion Elastic intramedullary nail has the advantages of short operation time,less intraoperative bleeding,short fracture healing time and less incision com-plications in the treatment of fibular fracture,which is worthy of clinical application.

Objective To investigate the regulatory effects of activated endoplasmic reticulum stress（ERS） and unfolded protein response（UPR） on the immune behavior of the stressed muscle fibers in inflammatory environments induced by interferon-γ（IFN-γ）. Methods The myogenic precursor cells（MPCs） of C57 BL/6 mice cultured in vitro were differentiated into multinucleated myogenic tubes by horse serum and then to set up: 1. Control group; 2. IFN-γ group; 3. Tunicamycin group; 4. Thapsigargin group; 5. IFN-γ and 4-phenylbutyrate（4-PBA） combined treatment group; 6. IFN-γ, TG and 4-PBA combined treatment group; 7. IFN-γ and 4μ8 c combined treatment group; 8. IFN-γ, TG and 4μ8 c combined treatment group; 9. IFN-γ and GSK2606414 combined treatment group; 10. IFN-γ, TG and GSK2606414 combined treatment group. The level of myokines gene was detected by Real-time PCR. The expression of UPR key molecules including eukaryotic intiatio factor 2α（eIF2α）, inositol requrring enzyme 1α（IRE1α） and activating transcription factor 6（ATF6） in muscle fibers was observed by immunofluorescence. Western blotting was used to detect immune molecules related to muscle cells, myokines and key molecules of UPR. Luminex analyzed the levels of pro-inflammatory myokines in muscle fibers. Results The expression of H-2 Kb, H2-Ea, Toll like receptor 3（TLR3）, p-eIF2α and p-IRE1α were up-regulated in IFN-γ induced inflammatory environment. The expression of H-2 Kb, H2-Ea, TLR3 and myokines in the group with UPR inhibitor 4-PBA was down-regulated compared with IFN-γ group, and the expression of these molecules in the group with IRE1α specific inhibitor 4μ8 c was down-regulated compared with the IFN-γ group. The addition of protein kinase R-like endoplasmic eticulum（PERK） specific inhibitor GSK2606414 showed no significant change. Conclusion In IFN-γ induced inflammatory environment, the UPR-IRE1α pathway activates and inhibits the synthesis of muscle fiber immune-related molecules, which further inhibits the muscle fiber mediated immune response and facilitates muscle regeneration.

OBJECTIVE: To explore the correlation between clinical phenotypes and pathogenic variants in two patients with familial hypercholesterolemia. METHODS: Both patients were subjected to whole exome sequencing (WES) with a focus on the analysis of genes associated with dyslipidemia. Candidate variants were verified by Sanger sequencing of the patients and their family members. RESULTS: WES revealed that the proband 1 has harbored two heterozygous variants of the LDLR gene, namely c.1360G>A (p.D454N) and c.292G>A (p.G98S), whilst proband 2 has harbored a heterozygous c.321T>G (p.C107W) variant of the LDLR gene. Based on the guidelines from the American College of Medical Genetic and Genomics (ACMG), the above variants were respectively predicted to be likely pathogenic (PM1+PM2+PP2+PP3+PP4+PP5), variant of unknown significance (PM1+PP2+PP3), and likely pathogenic (PM1+PM2+PP2+PP4+PP5). Treatment with PCSK9 inhibitor has attained a significant effect in proband 1 but no apparent effect in proband 2. CONCLUSION Variants of the LDLR gene probably underlay the familial hypercholesterolemia in the two pedigrees. The difference in the severity of the clinical phenotypes and response to PCSK9 inhibitor treatment between the two probands may be attributed to the different genotypes of the LDLR gene. Genetic testing not only can provide a basis for clinical diagnosis, but also facilitate the choice of lipid-lowering drugs.

During the coronavirus disease (COVID-19) epidemic, there have been concerns about the impact of vaccines on people's fertility, including the fertility of those who are currently preparing for pregnancy and those who might become pregnant in future. However, there is still a lack of research on the effect of the COVID-19 vaccine on male fertility, and it is not surprising that couples and donors have concerns regarding vaccination. In this study, a retrospective cohort study was conducted to examine semen quality before and after receipt of the inactivated COVID-19 vaccine. There were no statistically significant changes in semen parameters (volume, sperm concentration, progressive motility, and total progressive motile count) after two doses of vaccine (all P > 0.05). In summary, our study updates the most recent studies on the effects of the COVID-19 vaccine on male fertility, and the information from this study could be used to guide fertility recommendations for assisted reproductive technology (ART) patients and donors.

OBJECTIVE: To evaluate whether the efficacy of Getong Tongluo Capsule (, GTC, consisted of total flavone of Radix Puerariae) on improving patients' quality of life and lowering blood pressure are superior to the extract of Ginkgo biloba (EGB) for patients with convalescent-phase ischemic stroke and primary hypertension. METHODS: This randomized, positive-drug- and placebo-controlled, double-blind trial was conducted from September 2015 to October 2017. Totally 477 eligible patients from 18 hospitals in China were randomly assigned in a 2:1:1 ratio to the following interventions, twice a day for 12 weeks: (1) GTC 250 mg plus EGB-matching placebo 40 mg (237 cases, GTC group), (2) EGB 40 mg plus GTC-matching placebo 250 mg (120 cases, EGB group) or (3) GTC-matching placebo 250 mg plus EGB-matching placebo 40 mg (120 cases, placebo group). Moreover, all patients were orally administered aspirin enteric-coated tablets 100 mg, once a day for 12 weeks. The primary outcome was the Barthel Index (BI). The secondary outcomes included the control rate of blood pressure and National Institutes of Health Stroke Scale (NIHSS) scores. The incidence and severity of adverse events (AEs) were calculated and assessed. RESULTS: The BI relative independence rates, the clinical recovery rates of NIHSS, and the total effective rates of NIHSS in the GTC and EGB groups were significantly higher than the placebo group at 12 weeks after treatment (P<0.05), and no statistical significance was found between the GTC and EGB groups (P>0.05). The control rate of blood pressure in the GTC group was significantly higher than the EGB and placebo groups at 12, 18 and 24 weeks after treatment (P<0.01). There were no statistically significant differences in the incidences of AEs, adverse drug reactions, or serious AEs among the 3 groups (P>0.05). CONCLUSION GTC exhibited significant efficacy in improving patients' quality of life as well as neurological function and controlling hypertension. (Registration No. ChiCTR1800016667).

OBJECTIVE To investigate the pharmacological effect of ursolic acid (UA) on colitis-associated colorec?tal cancer (CAC) and its underlying mechanism based on the Wnt signaling pathway. METHODS The CAC model in mice was established by azoxymethane (AOM) combined and dextran sulfate sodium salt (DSS), accompanied by treat?ment with various dosages of UA and concomitant appraisal of body weight, stool and physical state of the mice. After the sacrifice of the mice, the tumor and length of the colorectum were measured, followed by retrieval of the liver, spleen, thymus and tumor tissue for downstream assays. The levels of inflammatory factors interleukin-6 (IL-6), IL-1βand C-reactive protein (CRP) in the tumor and serum were examined by enzyme-linked immunosorbent assay (ELISA). The pathological changes of colorectal tissues were observed by HE staining. The levels in tumors of Wnt/β-catenin sig?naling pathway-related proteins Wnt4, GSK-3β, β-catenin, TCF4, LEF1, c-Myc, cyclin D1 and apoptosis-related protein Bcl-2 were assayed by immunohistochemistry (IHC). The mRNA expressions of Wnt4, GSK-3β,β-catenin, TCF4, LEF1, c-Myc, cyclin D1, Bcl-2, Bax, caspase-9 and caspase-3 in tumors were detected by real-time quantitative RT-PCR (RT-qPCR). The protein levels of Wnt4, GSK-3β, β-catenin, TCF4, LEF1, c-Myc, cyclin D1, phospho-β-catenin, phospho-GSK-3β, Bcl-2 and Bax in tumors were probed by analyzed by Western blotting (WB). Also, RNA-seq was employed to assess the gut microbiota in the mice. RESULTS UA significantly ameliorated the symptoms of AOM/DSS-induced mouse CAC, evidenced by improved physical state, body weight, survival rate, colorectal length, the mass of liver, thy?mus, spleen, and decreased CAC load and colorectal mass. UA attenuated the levels of IL-6, IL-1β and CRP in the mouse serum and colorectal tumor in a dose-dependent manner. HE staining showed that UA lessened carcinogenesis in the colorectum, with lower infiltration of lymphocytes, versus the control. IHC indicated that UA mitigated the expres?sion of Wnt4,β-catenin, TCF4, LEF1, c-Myc, cyclin D1, Bcl-2, and promoted the GSK-3βexpression, compared with the control. Furthermore, UA diminished the mRNA expressions of Wnt4, β-catenin, TCF4, LEF1, c-Myc, cyclin D1, Bcl-2, and heightened the mRNA levels of GSK-3β, caspase-3, capase-9 and Bax in CAC. The results of mRNA expressions were verified by WB analysis, which revealed that UA impeded the protein expression of Wnt4,β-catenin, c-Myc, cyclin D1, Bcl-2, TCF4, LEF1, and elevated the protein levels of GSK-3βand Bax, phospho-β-catenin in mouse CAC. In addi?tion, UA substantially ameliorated the gut microbiota to store the metabolic function in the mice with CAC. CONCLU?SION Ursolic acid may protect against CAC, potentially by downregulation of Wnt/β-catenin signaling pathway activity and restoration of gut microbiota.
