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 study the effect of macrophage mediator 1 (MED1) deficiency on atherosclerosis in female mice. 【Methods】 ApoE knockout (ApoE^-/-), LDLR knockout (LDLR^-/-), MED1^fl/fl, and macrophage MED1 knockout (MED1^△Mac) mice were recruited in the study. Two types of mouse model were constructed:ApoE and macrophage MED1 double knockout (MED1^△Mac/ApoE^-/-) mice and their littermate controls (MED1^fl/fl/ApoE^-/-). ② LDLR knockout (LDLR^-/-) mice receiving bone marrow from MED1^△Mac (MED1^△Mac→LDLR^-/-) or MED1^fl/fl (MED1^fl/fl→LDLR^-/-) mice. Female mice from these two models were fed a Western diet (21% fat and 0.15% cholesterol) for 12 weeks to promote the development of atherosclerosis. Body weight, total cholesterol (TC), and total triglyceride (TG) content in plasma were measured dynamically. After Western diet feeding for 12 weeks, aortic tree and aortic root were collected and hematoxylin-eosin (H&E) and oil red O staining were performed. 【Results】 Plasma TC and TG did not significantly differ between MED1^fl/fl/ApoE^-/- control group and MED1^△Mac/ApoE^-/-experimental group. However, the plaque area in aortic tree and aortic root was significantly increased in MED1^△Mac/ApoE^-/-mice. Moreover, compared with that in MED1^fl/fl→LDLR^-/- control group, the plaque area of aortic tree and aortic root had an increasing trend in MED1^△Mac→LDLR^-/- mice group. 【Conclusion】 MED1 deficiency in macrophages promotes the development of atherosclerosis in female ApoE or LDLR knockout mice.

Objective:To investigate the therapeutic effect of bidirectional-traction, Steinmann pin poking reduction,anatomic plate and raft technique in the treatment of hyperextension tibial plateau fractures.Methods:The data of 25 patients with hyperextension tibial plateau fractures admitted to Qilu Hospital of Shandong University (Qingdao) from July 2017 to June 2022 were retrospectively analyzed. According to the treatment methods, they were divided into bidirectional-traction group (treated with bidirectional-traction, Steinmann pin poking reduction, anatomic plate and raft technique) and open reduction group (treated with open reduction, bone grafting and two plates fixation). The bidirectional-traction group included 14 patients, with 8 males and 6 females; the age was 50.29±9.23 years (range, 38-61 years). The cause of the injury was a traffic accident in 4 patients, a fall from height in 7 patients and a fall from standing height in 3 patients. According to Schatzker classification, there were 5 Schatzker type V and 9 type VI fractures. The open reduction group included 11 patients (7 males and 4 females); with a mean age of 58.00±10.58 years (range, 48-69 years). 3 cases were injured by traffic accident, 6 cases by falling from height, and 2 cases by falling from standing height. According to Schatzker classification, there were 4 type V and 7 type VI. Preoperative waiting time, operative time, blood loss and percentage of blood loss, incision length, fracture healing time, tibial posterior inclination, medial proximal tibial angle, visual analogue scale (VAS) on the first day after surgery, Hospital for Special Surgery (HSS) score 6 months after surgery were compared between the two groups.Results:Patients in both groups were followed up for more than 6 months. The follow-up time was 7 to 48 months with an average of 22.76 months. There were significant differences in the preoperative waiting time [6 (4, 8) d vs. 8 (7, 11) d, W=114.00, P=0.043], the incision length [15.0 (12.5, 16.0) cm vs. 30.0 (28.0, 31.0) cm, W=154.00, P<0.001], postoperative VAS [4 (3, 4) points vs. 5 (5, 6) points, W=143.00, P<0.001], blood loss [147 (107, 206) ml vs. 267 (191, 362) ml, W=116.00, P=0.033], blood loss percentage [2.95% (2.58%, 5.20%) vs. 6.40% (4.05%, 7.00%), W=118.00, P=0.027] between the bidirectional-traction group and open reduction group. There were not significant differences in the operation time [120 (118, 120) min vs. 119 (101, 154) min, W=68.50, P=0.656], fracture healing time (8.18±1.03 weeks vs. 8.86±1.27 weeks, t=1.49, P=0.149), HSS score (8.43±3.72 vs. 85.18±7.73, t=1.28, P=0.221) and medial proximal tibial angle 6 months after surgery (87.66°±1.53° vs. 86.47°±2.24°, t=1.57, P=0.130) between the two groups. Postoperative tibial posterior inclination was improved in both groups. There was no significant difference in the tibial posterior inclination before surgery, immediately after surgery and 6 months after surgery (-14.96°±6.44°, 5.55°±1.02°, 5.61°±0.82°) in the bidirectional-traction group and -12.26°±2.93°, 7.07°±3.21° and 7.14°±3.17° in the open reduction group, P>0.05). There were no postoperative complications such as acute compartment syndrome or knee stiffness in both groups. Conclusion:The treatment of hyperextension tibial plateau fracture with bidirectional-traction, Steinmann pin poking reduction, anatomic plate and raft technique can shorten preoperative waiting time, reduce incision length, decrease blood loss and lower VAS. It is a minimally invasive, rapid and effective method, which has achieved good clinical results and is worth promoting.

A new variant of concern for SARS-CoV-2,Omicron(B.1.1.529),was designated by the World Health Organization on November 26,2021.This study analyzed the viral genome sequenc-ing data of 108 samples collected from patients infected with Omicron.First,we found that the enrichment efficiency of viral nucleic acids was reduced due to mutations in the region where the primers anneal to.Second,the Omicron variant possesses an excessive number of mutations compared to other variants circulating at the same time(median:62 vs.45),especially in the Spike gene.Mutations in the Spike gene confer alterations in 32 amino acid residues,more than those observed in other SARS-CoV-2 variants.Moreover,a large number of nonsynonymous mutations occur in the codons for the amino acid residues located on the surface of the Spike protein,which could potentially affect the replication,infectivity,and antigenicity of SARS-CoV-2.Third,there are 53 mutations between the Omicron variant and its closest sequences available in public databases.Many of these mutations were rarely observed in public databases and had a low muta-tion rate.In addition,the linkage disequilibrium between these mutations was low,with a limited number of mutations concurrently observed in the same genome,suggesting that the Omicron vari-ant would be in a different evolutionary branch from the currently prevalent variants.To improve our ability to detect and track the source of new variants rapidly,it is imperative to further strengthen genomic surveillance and data sharing globally in a timely manner.

SARS-CoV-2 is a new RNA virus affecting humans and spreads extensively throughout the world since its first outbreak in December,2019.Whether the transmissibility and pathogenicity of SARS-CoV-2 in humans after zoonotic transfer are actively evolving,and driven by adaptation to the new host and environments is still under debate.Understanding the evolutionary mechanism underlying epidemiological and pathological characteristics of COVID-19 is essential for predicting the epidemic trend,and providing guidance for disease control and treatments.Interrogating novel strategies for identifying natural selection using within-species polymorphisms and 3,674,076 SARS-CoV-2 genome sequences of 169 countries as of December 30,2021,we demonstrate with popula-tion genetic evidence that during the course of SARS-CoV-2 pandemic in humans,1)SARS-CoV-2 genomes are overall conserved under purifying selection,especially for the 14 genes related to viral RNA replication,transcription,and assembly;2)ongoing positive selection is actively driving the evolution of 6 genes(e.g.,S,ORF3a,and N)that play critical roles in molecular processes involving pathogen-host interactions,including viral invasion into and egress from host cells,and viral inhi-bition and evasion of host immune response,possibly leading to high transmissibility and mild symptom in SARS-CoV-2 evolution.According to an established haplotype phylogenetic relation-ship of 138 viral clusters,a spatial and temporal landscape of 556 critical mutations is constructed based on their divergence among viral haplotype clusters or repeatedly increase in frequency within at least 2 clusters,of which multiple mutations potentially conferring alterations in viral transmis-sibility,pathogenicity,and virulence of SARS-CoV-2 are highlighted,warranting attention.

We reported a case of polyglandular syndrome induced by programmed death-1(PD-1) inhibitors. The patient was a 51-years-old male with non-small cell lung cancer, treated with PD-1 inhibitor nivolumab/pembrolizumab because of postoperative subcarinal lymph node metastasis indicated by PET-CT. During 14 cycles of PD-1 inhibitor treatment, the patient successively developed primary hypothyroidism, and type 1 diabetes mellitus(T1DM). More than five months after the withdrawal of pembrolizumab, the patient experienced recurrentce. Laboratory examinations showed mild hyponatremia and hypopituitarism including ACTH and growth hormone(GH)/insulin-like growth factor-1(IGF-1) insufficiency. This is the first report of a patient diagnosed as polyglandular syndrome caused by PD-1 inhibitor. In particularly, the hypothyroidism and T1DM did not improve after drug withdrawal, while hypopituitarism was further aggravated. This case reminds us that we should pay more attention to the changes of endocrine function during and after the treatment of PD-1 inhibitor, so that we can make the correct diagnosis and take proper medical measures timely, to avoide missed diagnosis, and improper treatment.

The Genome Sequence Archive (GSA) is a data repository for archiving raw sequence data, which provides data storage and sharing services for worldwide scientific communities. Considering explosive data growth with diverse data types, here we present the GSA family by expanding into a set of resources for raw data archive with different purposes, namely, GSA (https://ngdc.cncb.ac.cn/gsa/), GSA for Human (GSA-Human, https://ngdc.cncb.ac.cn/gsa-human/), and Open Archive for Miscellaneous Data (OMIX, https://ngdc.cncb.ac.cn/omix/). Compared with the 2017 version, GSA has been significantly updated in data model, online functionalities, and web interfaces. GSA-Human, as a new partner of GSA, is a data repository specialized in human genetics-related data with controlled access and security. OMIX, as a critical complement to the two resources mentioned above, is an open archive for miscellaneous data. Together, all these resources form a family of resources dedicated to archiving explosive data with diverse types, accepting data submissions from all over the world, and providing free open access to all publicly available data in support of worldwide research activities.

The Genome Warehouse (GWH) is a public repository housing genome assembly data for a wide range of species and delivering a series of web services for genome data submission, storage, release, and sharing. As one of the core resources in the National Genomics Data Center (NGDC), part of the China National Center for Bioinformation (CNCB;https://ngdc.cncb.ac.cn), GWH accepts both full and partial (chloroplast, mitochondrion, and plasmid) genome sequences with different assembly levels, as well as an update of existing genome assemblies. For each assembly, GWH collects detailed genome-related metadata of biological project, biological sample, and genome assembly, in addition to genome sequence and annotation. To archive high-quality genome sequences and annotations, GWH is equipped with a uniform and standardized procedure for quality control. Besides basic browse and search functionalities, all released genome sequences and annotations can be visualized with JBrowse. By May 21, 2021, GWH has received 19,124 direct submissions covering a diversity of 1108 species and has released 8772 of them. Collectively, GWH serves as an important resource for genome-scale data management and provides free and publicly accessible data to support research activities throughout the world. GWH is publicly accessible at https://ngdc.cncb.ac.cn/gwh.

COVID-19 has swept globally and Pakistan is no exception.To investigate the initial introductions and transmissions of the SARS-CoV-2 in Pakistan,we performed the largest genomic epidemiology study of COVID-19 in Pakistan and generated 150 complete SARS-CoV-2 genome sequences from samples collected from March 16 to June 1,2020.We identified a total of 347 mutated positions,31 of which were over-represented in Pakistan.Meanwhile,we found over 1000 intra-host single-nucleotide variants(iSNVs).Several of them occurred concurrently,indicating possible interactions among them or coevolution.Some of the high-frequency iSNVs in Pakistan were not observed in the global population,suggesting strong purifying selections.The genomic epidemiology revealed five distinctive spreading clusters.The largest cluster consisted of 74 viruses which were derived from different geographic locations of Pakistan and formed a deep hierarchical structure,indicating an extensive and persistent nation-wide transmission of the virus that was probably attributed to a signature mutation(G8371T in ORF 1ab)of this cluster.Further-more,28 putative international introductions were identified,several of which are consistent with the epidemiological investigations.In all,this study has inferred the possible pathways of introduc-tions and transmissions of SARS-CoV-2 in Pakistan,which could aid ongoing and future viral surveillance and COVID-19 control.
