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 compliance with early Warfarin anticoagulation therapy after cardiac mechanical valve replacement(MHVR)and its related factors in elderly patients.Methods:The convenience sampling method was used to prospectively recruit 210 patients undergone MHVR at the Ningbo Medical Center of Lihuili Hospital from January 2017 to October 2019.Six months after discharge, face-to-face interviews or telephone follow-ups were conducted to assess general information, warfarin anticoagulation knowledge, anticoagulant treatment compliance and social support.Results:The overall compliance of early Warfarin anticoagulation therapy was excellent, with 99.5% of patients compliant with medication and 99.0% compliant with INR monitoring, both higher than the rate of compliance with advised lifestyle adjustment(92.1%). Anticoagulation knowledge and age were the main influencing factors for compliance in elderly patients after MHVR.Conclusions:The compliance with early Warfarin anticoagulation therapy after MHVR is good in elderly patients in the Ningbo area.The correlation analysis suggests that medical professionals need to promote education on anticoagulation knowledge and pay more attention to anticoagulation compliance in elderly people.

Objective:To explore the genetic characteristics and evolution of hantavirus carried by rodents in port area of Ningde in Fujian province in the summer of 2020.Methods:Rodents were captured in the port area of Ningde, the RNA was extracted from rodent lung tissues and detected by using specific kit. The positive samples were used for whole-genome sequencing of the virus. Bioinformatics software was used for the analysis on the similarity and genetic variation of the sequences.Results:A total of 112 rodents were captured, including 5 Rattus norvegicus and 2 Rattus flavipectus, the positive rate of hantavirus was 6.25% (7/112). By virus gene sequencing, two hantavirus complete genome sequences were obtained (named as FJ35 and FJ36, GenBank accession numbers: MW449188-MW449193). The genetic analysis results showed that the hantavirus detected in positive samples were SEOV and shared 99% nucleotide similarity with hantavirus strains LZSF21 and JX20140581 isolated from Shandong province. Phylogenetic analysis using the maximum likelihood method showed that the hantavirus detected in positive samples belonged to S3 subtype, sharing the same subtype with hantavirus strains Z37 from Zhejiang province, LZSF21 from Shandong province, and zy27 and Gongzhuling 415 from northeastern China. Compared with FJ372, the amino acid variation of N259S was observed at sites 251-264 of nucleoprotein, which might be related to antigenicity. Another variation of Q81R was observed in glycoprotein compared with SEOV 80-39 segment of coded amino acid of international reference strain, which might also cause the change in antigenicity. Conclusion:The high positive rate of hantavirus in rodents in the port area of Ningde- would increase the risk of natural human infection and epidemic in local area. The hantavirus positive rodents in this focus might be from an endemic area in Shandong. It is necessary to strengthen the imported rodent control in the port area of Ningde. The virus detected in 2 positive samples belonged to SEOV subtype Ⅲ and shared high homologies of nucleotides and amino acid sequences with the hantavirus strains in surrounding area. However, some slight variations occurred in glycoprotein and nucleoprotein amino acid sequences, which might cause changes in its antigeniity.

With the aging of the Chinese society and the population, the incidence of hip fractures in the elderly is increasing significantly. Elderly patients have various basic diseases and decreased organ compensatory capacity, which increase the risks related to surgery and anesthesia, increase the incidence of postoperative complications and mortality, and affect the recovery process of patients. Malnutrition is one of the main causes of hip fractures in elderly patients, and it is also a major factor predicting the prognosis of patients. Elderly patients with hip fractures are considered at high risk of malnutrition. Malnutrition can lead to adverse clinical outcomes, such as increased mortality and complications, prolonged hospital stays, and increased hospital costs. Elderly patients with hip fracture should be routinely screened for nutritional risk. Those with malnutrition or nutritional risk, should be given nutritional support treatment. And conduct assessments and optimizations of nutritional support treatmentby observing the prognosis indicators such as complication rate, mortality, and rehabilitation status. At present, orthopedic surgeons who are the main body of elderly hip fracture treatment do not pay enough attention to the nutritional status of patients. Many elderly hip fracture patients undergo surgery while their malnutrition status has not improved. Therefore, it is important to improve their prognosis that strengthen the perioperative nutritional management of elderly patients with hip fracture. Domestic research on the nutritional status of elderly hip fracture patients started late. Many medical institutions have not carried out routine nutritional screening and active nutritional support treatment for elderly hip fracture patients, and there is also a lack of relevant clinical research and data statistics in the nutritional support and treatment of elderly patients with hip fractures. This article describes the current research status of nutritional risk screening and nutritional support treatment for elderly patients with hip fracture at home and abroad. However, due to differences in ethnicity, lifestyle, religious culture, and eating habits in various regions, foreign research data may not be suitable for domestic patients. Therefore, this article provides a reference for the research on perioperative nutritional screening and nutritional treatment of elderly hip fracture patients, and establishes a nutritional management plan suitable for elderly hip fracture patients in China.

Objective: To understand the serum levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine (T3), and thyroxine (T4) and identify the related influencing factors of thyroid dysfunction in drug users. Methods: From June to August 2018, a face-to-face questionnaire survey was conducted in 788 male drug users in a drug rehabilitation center in Jiangsu province to collect their socio-demographic information. Then, venous blood sample was collected from each participant for the detection of various hematological indicators, such as thyroid hormones. Results: The abnormal rates of T3, T4, FT3, FT4 and TSH were 4.57%, 1.27%, 0.51%, 0.38% and 0.89%, respectively, in the male drug users. HCV infection was an influencing factor for abnormal T3 level in the male drug users (OR=8.52, 95%CI: 2.36-30.74, P=0.001). And serum T3 (P<0.001) and T4 (P=0.048) levels increased with increasing HCV viral load. Conclusions HCV infection was an influencing factor for the abnormality of serum T3 level in drug users. Therefore, thyroid-related knowledge should be added in the health education for drug users, and the monitoring of thyroid function should be strengthened for drug users infected with HCV.

Objective: To explore the relationship between the tumor necrosis factor receptor superfamily members 11A (TNFRSF11A) and 11B (TNFRSF11B) gene polymorphisms and the outcome of hepatitis C virus (HCV) infection. Methods: In this case-control study, 749 cases of persistent HCV infection, 494 cases of spontaneous clearance and 1 486 control subjects were included from 2008 to 2016. TaqMan-MGB probe method was used to detect the genotype of TNFRSF11A rs1805034 and TNFRSF11B rs2073617. The genotypes distribution of the two single nucleotide polymorphisms (SNP) were analyzed in different populations. Results: Co-dominant model showed that individuals carrying the rs2073617 CC genotype were prone to have chronic HCV infection, compared with individuals carrying the rs2073617 TT genotype (OR=1.517, 95%CI: 1.055-2.181, P=0.024). Recessive model results showed that individuals carrying rs2073617 CC genotype were more likely to develop chronic HCV infection compared with individuals carrying rs2073617 TT or TC genotype (OR=1.435, 95%CI: 1.033-1.996, P=0.032). Additive model showed that the risk for chronic HCV infection increased with the increase of the number of rs2073617 C alleles (OR=1.204, 95%CI: 1.013-1.431, P=0.035). Conclusion The genetic polymorphism of TNFRSF11B rs2073617 might be related with the chronicity of HCV infection.

Curriculum integration and problem based learning (PBL) is the development trend of medical education all over the world,and it is an effective mode to train high-quality medical talents to meet the needs of the times and national medical and health services.However,PBL is difficult to popularize in an all-round way at present due to the large enrollment of clinical medicine major in medical colleges and universities in China.Aiming at integrating knowledge and focusing on ability,Nanjing Medical University implemented a problem-based two-way integrated case teaching after top-level design,careful trial and steady promotion and has achieved initial results and improved the clinical competency of medical students.

Objective To explore the influence factors for femoral head necrosis after treatment of femoral neck fractures with dynamic hip screw (DHS) and anti-rotation screw.Methods A retrospective case series analysis was made on the clinical data of 106 cases of femoral neck fractures who had undergone fixation with DHS and anti-rotation screw between May 2010 and May 2015.There were 59 males and 47 females,with an average age of 57.0 years (range,27-76 years).By Garden classification,there were 27 cases of type Ⅱ,51 cases of type Ⅲ and 28 cases of type Ⅳ.All cases were divided into femoral head necrosis group (18 cases) and none-necrosis group (88 cases) according to the radiographs of the fractured hip at the follow-up.Univariate analyses and a multivariate logistic regression analysis were made to test whether the following factors were significantly associated with femoral neck necrosis:sex,age,Garden classification,Pauwels classification,Singh index,injury-to-surgery time interval,reduction methods,reduction quality,complete weight-bearing time,implant removal and the time cost of implant removal surgery.Results All the 106 patients obtained a mean follow-up of 49 months (range,26-76 months).Femoral head necrosis occurred in 18 cases (17.0％).In univariate analyses,Garden classification,reduction quality,implant removal and long time of the implant removal surgery were significantly associated with femoral head necrosis (P ＜ 0.01).In multivariate logistic regression analysis,high level of Garden classification(95％ CI 0.008,0.998,P ＜ 0.05),implant removal and long time of the implant removal surgery (95％ CI 0.000,0.143,P ＜ 0.01) were found to have a significant effect on femoral head necrosis development.Conclusions Fracture displacement,removal of internal fixation and broadening the screw canal,which cand hinder the blood supply of femoral head,will enhance the rate of femoral head necrosis.As a result,it needs prudent consideration to remove internal fixation after internal fixation with DHS combined with anti-rotation screw for femoral neck fractures.When it is difficult to remove the anti-rotation screw,it is better to give up,rather than to force a removal.

Objective The incidence of liver fibrosis in patients with chronic hepatitis C is high.Without effective treatment,it would lead to liver cirrhosis.This study is to identify the related factors for the incidence of liver fibrosis in patients with chronic hepatitis C in order to make early intervention treatment and reduce the case fatality rate.Methods This cross-sectional survey was conducted in adults aged ≥50 years with local residence for more than 5 years in Jurong of Jiangsu province from March to May in 2015,the patients infected with hepatitis C virus through remunerated blood donation were screened and included in the analysis.Descriptive statistical analysis was done to compare the differences in the incidence of liver fibrosis among the patients with different age,sex and education level or co-infected with hepatitis B virus or not.The risk factors for severe liver fibrosis were identified with univariate and multivariate logistic regression analysis.Liver fibrosis was diagnosed by using FIB-4 index method.Results A total of 719 patients with chronic hepatitis C were surveyed.Severe liver fibrosis developed in 285 of the 719 patients,in whom 21.84％ was males.Multivariate logistic regression analysis showed that the patients with higher education level (OR=0.65,95％CI:0.47-0.90) and with access of antiviral therapy (OR=0.33,95％ CI:0.22-0.49) had lower risk for severe liver fibrosis,the patients with high fasting blood glucose level (OR=1.80,95％CI:1.19-2.77) and abnormal white blood cell count (OR=2.77,95％CI:1.95-3.90) had higher risk for severe liver fibrosis.Conclusions The incidence of severe liver fibrosis in patients with hepatitis C was affected by many factors.Higher education level and antiviral therapy were the protective factors,but high fasting blood glucose level and abnormal white blood cell count were the risk factors.

Objective To compare the efficacy and the risk of adverse effect of drug susceptibility test guided therapy and novel empirical quadruple therapy for Helicobacter (H.) pylori infection.Methods Literature retrieval was conducted by using major databases.Related papers published up to June 2015 were considered eligible if they were randomized control trials comparing different pharmacological formulations for H.pylori infection and used in a network Meta-analysis and a single rate Meta-analysis to evaluate the relative and absolute rates of H.pylori eradication and the risk of adverse effect.The Jadad score was used to evaluate the methodological quality.Funnel plot was constructed to evaluate the risk of publication bias.Begg's rank correlation test or Egger's regression intercept test was done for the asymmetry of funnel plot.Results Twenty randomized control trials for the treatment of 6 753 initial treated patients with H.pylori infection were included.Drug susceptibility test guided therapy was significantly superior to concomitant therapy,hybrid therapy,sequential therapy and bismuth quadruple therapy.The culture-based therapy had the highest likelihood of improving clinical efficacy,with lowest risk of adverse effect.Concomitant therapy had the highest probability of causing adverse effect despite its effectiveness.Hybrid therapy and bismuth quadruple therapy were associated with lower risk of adverse effect and higher effectiveness.Conclusion Drug susceptibility test guided therapy showed superiority to other 4 interventions for H.pylori eradication mentioned above.Hybrid therapy and bismuth quadruple therapy might be applied in the settings where the culture-based strategy is not available.
