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 explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.

Objective:To explore the relationship between integrin ɑ3(ITGA3)expression and immune cell infiltration in colorectal cancer(CRC).Methods:Bioinformatic methods were used to analyze ITGA3 mRNA expression in pan-cancer and CRC tissues,as well as its associ-ation with CRC prognosis.The correlation between ITGA3 and tumor-infiltrating immune cells was also investigated.In total,233 cases of CRC diagnosed at Shanxi Provincial Cancer Hospital between January and December 2021 were included,and ITGA3,CD8,CD163,FOXP3,PD-L1,CTLA-4,and PD-1 expression in CRC tissues were determined by immunohistochemistry(IHC)to analyze the relationship between ITGA3 and infiltrating immune cells and immune checkpoints.Results:Bioinformatics analysis showed elevated ITGA3 mRNA levels in CRC.High ITGA3 expression was associated with PFS(P＜0.05).Univariate and multifactorial analyses showed that age and stage were significantly cor-related with prognosis(P＜0.05).In addition,ITGA3 upregulation was closely correlated with multiple immune cell infiltration levels in CRC.Furthermore,IHC results showed that ITGA3 expression in CRC tissues was significantly higher than that in adjacent normal tissues(P＜0.05).ITGA3 expression was associated with lymph node metastasis(P＜0.05)and correlated with the expression of immune markers,such as CD8+T-cells,PD-L1,and CTLA-4(P＜0.05).Conclusions:ITGA3 is highly expressed in CRC,which is closely related to immune cell infiltration and may regulate the tumor immune microenvironment,which provides a new idea for clinical treatment and a potential new independent predictive marker.

Objective:To analyse the effect of the exposed bone cement technique combined with pectoralis major muscle flap in the treatment of chronic sternal osteomyelitis after coronary artery bypass surgery(CABS), and to summarise the clinical experience of staged surgery and comprehensive treatment.Methods:A retrospective analysis were carried out on 5 patients who had chronic sternal osteomyelitis and treated with exposed bone cement after the CABS from October 2017 to October 2020. Five patients(4 males and 1 female) met the inclusion criteria with a mean age of 65(range from 54 to 72) years old. Duration of all the chronic sternal osteomyelitis was 3 weeks to 3 months at admission. During the perioperative period, the general condition of the patients was controlled and systemic nutritional support was given. At the first stage, all patients underwent complete debridement. Then all the wounds were treated with exposed bone cement and covered by vacuum sealing drainage(VSD) to control the infection. At the second stage, bone cement was removed, and the dead cavity was packed with pectoralis major advancement muscle flap. Close attention was paid to the tension of wound, the patency of drainage catheter and the drainage after surgery. The wound healing, scar hyperplasia and complications were observed during the follow-up.Results:The suture tension was moderate, the drainage catheter was unobstructed, and a little liquid was drawn without turbid. All patients were clinically cured and entered follow-up for 6 to 15 months. During the follow-up, there was neigher recurrence of osteomyelitis nor sinus tract formation. No significant complication occurred at the last follow-up. The quality of life of the patients was significantly improved and all the patients were satisfactory to the treatment.Conclusion:Exposed bone cement technique combined with pectoralis major muscle flap is an effective method in the treatment of chronic sternal osteomyelitis after CABS. It has a good short-term treatment efficacy and is worthy for further clinical trials.

Objective: To investigate the clinical characteristics and diagnosis and treatment strategies of patients with severe traumatic aortic injury (TAI). Methods: A total of 25 patients with TAI, who hospitalized in our hospital between August 2005 to March 2021 and underwent thoracic aortic endovascular repair (TEVAR), were included in this retrospective study. According to the time from admission to TEVAR, the patients were divided into emergency TEVAR group (14 cases, TEVAR within 24 h of admission) and elective TEVAR group (11 cases, patients underwent surgery or fracture reduction and fixation first for serious injuries and then underwent TEVAR more than 24 h after admission). The general clinical data of patients, injury severity score (ISS), time from admission to intervention, total hospital stay, the proportion of closed chest drainage and the proportion of abdominal organ repair were obtained and compared. Clinical follow-up and 1-year postoperative aortic computed tomography angiography (CTA) were performed on the patients. Death, the occurrence of aortic adverse events and injury recovery were followed up and recorded. Results: The mean age of these 25 TAI patients was (41.4±14.4) years, 20 patients were males (80.0%). 21 patients (84.0%) had persistent chest and back pain, 17 (68.0%) had pleural effusion and 5 (20.0%) had mediastinal hematoma. The injury severity score (ISS) was significantly higher in the elective TEVAR group than in the emergency TEVAR group (24.9±14.4 vs. 35.5±9.3, P=0.044). The time from admission to intervention ((1.0±0.0) d vs. (3.4±0.9) d, P<0.001], the time from admission to TEVAR ((1.0±0.0) d vs. (11.5±13.8) d, P=0.030) and total hospital stay ((6.1±2.3) d vs. (26.8±7.7) d, P<0.001) were significantly longer in elective TEVAR group than in emergency TEVAR group. The proportion of thoracic closed drainage was significantly lower in the elective TEVAR group than in the emergency TEVAR group (9 (64.3%) vs. 2 (18.2%), P=0.042). The proportion of abdominal organ repair was significantly higher than in the emergency TEVAR group (0 vs. 4 (36.4%), P=0.026). All of 25 patients were discharged alive and followed up for (84.0±30.5) months. All patients survived and completed 1-year postoperation CTA. There were no aortic adverse events occurred, and no complications after surgery, and the fractures and organ injuries healed well. Conclusions: The clinical characteristics of severe TAI are acute multi-injuries combined with persistent chest and/or back pain, pleural effusion, and mediastinal hematoma. Timely diagnosis and treatment are important factors for the outcome. The treatment strategy for multi-injuries should give priority to dealing with life-threatening injuries. TEVAR is the primary treatment strategy for severe TAI and is related to satisfactory outcomes.

Objective:To investigate the preparation methods and quality control of 177Lu-labeled radiopharmaceuticals, and conduct preliminary clinical application research. Methods:177Lu-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)- D-Phe1-Tyr3-octreotide (TOC) and 177Lu-prostate specific membrane antigen (PSMA)-I&T were labeled by manual labeling and automatic labeling, respectively. Factors such as the amount of precursor and nuclide, reaction temperature, pH value, reaction time, labeling yield and specific activity were investigated. Quality control of the products were carried out, such as clarity, pH value, sterility, bacterial endotoxin and stability in vitro. 177Lu-PSMA-I&T was applied to the treatment of prostate cancer patients, and the efficacy was evaluated by SPECT/CT imaging. Paired t test was used to analyze the data. Results:The amount of precursor and nuclide, reaction temperature, pH value and reaction time of the two methods were basically the same, both with high yield and specific activity. The yield of 177Lu-DOTA-TOC automatic labeling was significantly higher than that of manual labeling (99.2±0.4)% vs (95.3±1.5)% ( t=7.17, P<0.001), and the specific activity were (91.6±13.7) vs (89.1±13.2) GBq/μmol. The yield of 177Lu-PSMA-I&T automatic labeling was also significantly higher than that of manual labeling (99.6±0.3)% vs (95.7±1.3)% ( t=8.24, P<0.001), and the specific activity were (96.1±14.3) vs (93.2±13.8) GBq/μmol. The labeled products were colorless clear solution with pH value of 6.5-7.0. The sterility and bacterial endotoxin met the requirements. The radiochemical purity of the labeled products was more than 95% after 48 h, which showed good stability. The clinical application of 177Lu-PSMA-I&T in patients with prostate cancer showed that both primary and metastatic lesions had good uptake. Conclusions:The labeling of 177Lu radiopharmaceuticals is simple and has high yield and stability. The application of automatic labeling can simplify the process, improve the yield and reduce irradiation.

To evaluate whether the polygenic profile modifies the development of sporadic Alzheimer's disease (sAD) and pathological biomarkers in cerebrospinal fluid (CSF), 462 sAD patients and 463 age-matched cognitively normal (CN) controls were genotyped for 35 single-nucleotide polymorphisms (SNPs) that are significantly associated with sAD. Then, the alleles found to be associated with sAD were used to build polygenic risk score (PRS) models to represent the genetic risk. Receiver operating characteristic (ROC) analyses and the Cox proportional hazards model were used to evaluate the predictive value of PRS for the sAD risk and age at onset. We measured the CSF levels of Aβ42, Aβ42/Aβ40, total tau (T-tau), and phosphorylated tau (P-tau) in a subgroup (60 sAD and 200 CN participants), and analyzed their relationships with the PRSs. We found that 14 SNPs, including SNPs in the APOE, BIN1, CD33, EPHA1, SORL1, and TOMM40 genes, were associated with sAD risk in our cohort. The PRS models built with these SNPs showed potential for discriminating sAD patients from CN controls, and were able to predict the incidence rate of sAD and age at onset. Furthermore, the PRSs were correlated with the CSF levels of Aβ42, Aβ42/Aβ40, T-tau, and P-tau. Our study suggests that PRS models hold promise for assessing the genetic risk and development of AD. As genetic risk profiles vary among populations, large-scale genome-wide sequencing studies are urgently needed to identify the genetic risk loci of sAD in Chinese populations to build accurate PRS models for clinical practice.

This paper explores Mongolian medicine processing methods and the use regularity of excipient by text mining techniques. Relevant books of Mongolian medicine processing were consulted to collect data on Mongolian medicine processing methods and excipient, and select data based on processing methods and excipient noun frequency statistics. Microsoft Excel 2010 software was used for statistical analysis and mining for the usage regularity of different types of Mongolian medicinal materials in different periods. And Cytoscape 3.6.1 software was used for visual presentation. The topological analysis showed the top five processing methods were net production, development, frying, calcining and cooking, and the top five processing excipient were fresh milk, wine, urine, cream and mineral borax. Frequency analysis showed that the plant medicinal materials were mostly recorded in the 18~(th) and 21~(st) centuries, especially in the 21 st century; the processing methods mostly contained water processing, repair processing and other methods. The mineral medicinal materials were mostly recorded in the 18~(th), 19~(th) and 21~(st) centuries; most of the processing methods were the fire processing method. The animal medicinal materials were recorded in the 18~(th), 19~(th) and 21~(st) century; the fire processing method occupied a major position, and the repair processing and the grinding processing were markedly increased in the 21~(st) century. In the use of excipient, liquid excipient were mostly used in plant medicines. Solid excipient were most commonly used in the 18~(th) century. Animal excipient were mostly used during the processing in the 18~(th) century. The use of liquid excipient gradually increased in the 19~(th) and 21~(st) centuries. This study summarizes the traditional processing methods of Mongolian medicine and the usage regularity of excipient, defines the characteristics of Mongolian medicine processing methods and excipient, and the characteristics of the combination of medicinal materials and excipient, so as to provide reference for the clinical use of Mongolian medicine.

AIM:To investigate the effect of salvianolic acid B (Sal B) on high glucose-induced phenotypic transition and extracellular matrix (ECM) secretion in human glomerular mesangial cells (HGMCs) and the underlying mechanisms.METHODS:HGMCs were randomly divided into control group, high glucose group and high glucose plus high dose, medium dose and low dose of Sal B groups.The HGMCs except those in control group were exposed to high glucose (33.3 mmol/L) for 72 h, while those in Sal B groups were co-incubated with indicated concentrations of Sal B.The protein levels ofα-smooth muscle actin (α-SMA) , transforming growth () and phosphorylated Smad2 and p38 mitogen-activated protein kinase (MAPK) were determined by Western blot.The secretion levels of collagen type I (Col I) , collagen type III (Col III) , fibronectin (FN) and laminin (LN) were measured by ELISA.RESULTS:Exposure to high glucose markedly increased the protein expression ofI, Col III, FN and LN in the HG-MCs (P<0.01).The phosphorylation levels of Smad2 and p38 MAPK were also significantly increased (P<0.01).Coincubation with Sal B evidently decreased the protein expression ofI, Col III, FN and LN in the HGMCs induced by high glucose (P<0.05 or P<0.01).The phosphorylated levels of Smad2 and p38 MAPK were also reduced noticeably (P<0.05 or P<0.01).CONCLUSION:Sal B significantly suppresses high glucose-induced phenotypic transition and ECM secretion in the HGMCs, which might be attributed, at least partly, to inhibition ofSmad signaling pathway and p38 MAPK activation.
