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.

Background The incidence of Legionnaires' disease is increasing globally and artificial water environment is becoming a common source of outbreaks. Molecular typing techniques can help prevent and control Legionella. Objective To understand the molecular epidemiological characteristics of Legionella pneumophila in artificial water environment of Shanghai hospitals, and provide a scientific basis for the prevention and control of Legionnaires' disease. Methods Water samples were collected from artificial water environment in 14 hospitals from May to October each year from 2019 to 2020 in Shanghai. A total of 984 water samples were collected from 8 Grade-A tertiary hospitals and 6 non-Grade-A tertiary hospitals, including 312 samples of cooling water, 72 samples of chilled water, and 600 samples of tap water. The water samples were isolated and serotyped for Legionella pneumophila and preserved, and the positive rate of Legionella pneumophila in the samples was used as an indicator of contamination. The preserved strains were resuscitated and 81 surviving strains were obtained for pulsed field gel electrophoresis (PFGE) typing analysis. Results A total of 124 Legionella pneumophila positive water samples were detected, with a positive rate of 12.60%. The positive rate was higher in the Grade-A tertiary hospitals (16.54%, 87/526) than in the non-Grade-A tertiary hospitals (8.08%, 37/458) (χ²=15.91, P<0.001). The positive rate of cooling water (23.40%) was the highest among different types of water samples, and the difference was statistically significant (χ²=61.19, P<0.001). The difference in positive rate of tap water was statistically significant among different hospital departments (χ²=11.37, P<0.05). The positive rate in 2019 (15.06%) was higher than that in 2020 (9.84%) (χ²=6.23, P<0.05). From May to October, August had the highest annual average positive rate (16.46%) and October had the lowest (8.54%), but the difference in positive rates among months was not statistically significant (χ²=5.39, P=0.37). The difference in positive rate among districts was statistically significant (χ²=24.88, P<0.001). A total of 131 strains of Legionella pneumophila were isolated, with serotype 1 (80.15%, 105/131) predominating. Among the 81 surviving strains of Legionella pneumophila subjected to PFGE typing, the band-based similarity coefficients ranged from 41.30% to 100%. Among the 29 PFGE band types (S1-S29) recorded, each band type included 1-10 strains, and S28 was the dominant band type. Four clusters (I-IV) of PFGE band types were identified, accounting for 66.67% (54/81) of all strains and containing 13 band types. Conclusion Legionella pneumophila contamination is present in the artificial water environment of hospitals in Shanghai from 2019 to 2020, and the contamination in tap water deserves attention. The detected serotype of Legionella pneumophila is predominantly type 1, and PFGE typing reveals the presence of genetic polymorphism. Therefore, the monitoring and control of Legionella pneumophila in hospital artificial water environment should be strengthened.

Objective:To analyze potential roles of mechanical stress in the formation of plantar melanoma.Methods:A retrospective analysis was conducted on 129 cases of plantar melanoma in Xiangya Hospital, Central South University between 2014 and 2021, and the distribution and clinical characteristics of plantar melanoma were analyzed. The goodness-of-fit test was used to compare the distribution of plantar melanoma between weight-bearing areas (the toes, forefoot, lateral midfoot, heel) and non-weight-bearing areas of the foot (the arch) , while t test, Fisher′s exact test and Wilcoxon rank sum test were used to analyze differences in clinicopathological characteristics of plantar melanoma between weight-bearing areas and non-weight-bearing areas of the foot. Results:Among the 129 patients with plantar melanoma, 66 (51.2%) were males and 63 (48.8%) were females, and their age at onset was 60.6 ± 13.1 years. Plantar melanoma mostly occurred on the heel (65 lesions, 1.31 lesions per square centimeter) , followed by the forefoot (31 lesions, 0.41 lesions per square centimeter) , the bottom of the toes (15 lesions, 0.43 lesions per square centimeter) , lateral midfoot (11 lesions, 0.38 lesions per square centimeter) and the arch of foot (7 lesions, 0.16 lesions per square centimeter) . The goodness-of-fit test showed that melanoma was more prone to occur in the weight-bearing areas than in the non-weight-bearing areas ( χ2 = 66.59, P < 0.001) ; compared with the arch of foot, a higher incidence density was observed in the heel and forefoot ( χ2 = 38.29, 5.23, P < 0.001, = 0.022, respectively) . There were no significant differences in the gender ratio, age and occupation of patients, prevalence rates of left/right foot involvement, Breslow thickness, ulceration status, Clark grades, lymph node metastasis rate, and stages between melanomas in the weight-bearing areas and those in non-weight-bearing areas (all P > 0.05) . Conclusion:Plantar melanoma was more prone to occur in the weight-bearing areas than in the non-weight-bearing areas, suggesting that mechanical stress may be related to the occurrence and development of melanoma.

Objective:To investigate the clinical effect of spousal kidney transplantation , and to explore the significance in today's society.Methods:We retrospectively collected the relevant clinical data from the transplantation department of the first hospital of jilin university, from October 2009 to December 2018. Receptors who accepted spousal, parental and compatriot donor kidney is respectively obtained.Then the postoperative efficacy of the three groups were compared.Results:The graft survival rates of spousal kidney transplantation were 94.1% at 3 years and 83.7% at 5 years, which were not significantly different from other types of living kidney transplantation ( P=0.260). There was no significant difference in creatinine at each time point within 3 years after operation between three groups. At 3 years and 5 years after operation, there was no significant difference in creatinine between spouse group and sibling group.But the creatinine of spouse group was lower compared with parent group ( P=0.014, 0.038). The incidence of rejection within 1 years after spousal renal transplantation was 25%, which was significantly higher than parent group and sibling group ( P=0.029). Age of donor, gender of recipient, D/R BMI and incidence of AR or not in recipient were independent predictors for 1-year creatinine in living kidney transplantation (correlation coefficient: 0.048、-26.03、-15.95、10.23; P=0.003、<0.001、0.021、0.013). Conclusions:Spousal kidney transplantation has same clinical efficacy compared with other types of living kidney transplantation, which can greatly improve the donor kidney resource.So it worth being further promotion, but compared with other types of living kidney transplantation, we should be more alert to the incidence of rejection reaction, so as to obtain better curative effect.
