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.

Objective: To explore the development of the pancreatic surgeon technique in a high-volume center. Methods: A total of 284 cases receiving pancreatic surgery by a single surgeon from June 2015 to December 2020 were retrospectively included in this study. The clinical characteristics and perioperative medical history were extracted from the medical record system of Zhongshan Hospital,Fudan University. Among these patients,there were 140 males and 144 females with an age (M (IQR)) of 61.0 (16.8) years(range: 15 to 85 years). The "back-to-back" pancreatic- jejunal anastomosis procedure was used to anastomose the end of the pancreas stump and the jejunal wall. Thirty days after discharge,the patients were followed by outpatient follow-up or telephone interviews. The difference between categorical variables was analyzed by the Chi-square test or the CMH chi-square test. The statistical differences for the quantitative data were analyzed using one-way analysis of variance or Kruskal-Wallis H test and further analyzed using the LSD test or the Nemenyi test,respectively. Results: Intraoperative blood loss in pancreaticoduodenectomy between 2015 and 2020 were 300,100(100),100(100),100(0),100(200) and 150 (200) ml,respectively. Intraoperative blood loss in distal pancreatectomy was 250 (375),100 (50),50 (65), 50 (80),50 (50),and 50 (100) ml,respectively. Intraoperative blood loss did not show statistical differences in the same operative procedure between each year. The operative time for pancreaticoduodenectomy was respectively 4.5,5.0(2.0),5.5(0.8),5.0(1.3),5.0(3.3) and 5.0(1.0) hours in each year from 2015 to 2020,no statistical differences were found between each group. The operating time of the distal pancreatectomy was 3.8 (0.9),3.0 (1.5),3.0 (1.8),2.0 (1.1),2.0 (1.5) and 3.0(2.0) hours in each year,the operating time was obviously shorter in 2018 compared to 2015 (P=0.026) and 2020 (P=0.041). The median hospital stay in 2020 for distal pancreatectomy was 3 days shorter than that in 2019. The overall incidence of postoperative pancreatic fistula gradually decreased,with a incident rate of 50.0%,36.8%,31.0%,25.9%,21.1% and 14.8% in each year. During this period,in a total of 3,6,4,2,0 and 20 cases received laparoscopic operations in each year. The incidence of clinically relevant pancreatic fistula (grade B and C) gradually decreased,the incident rates were 0,4.8%,7.1%,3.4%,4.3% and 1.4%,respectively. Two cases had postoperative abdominal bleeding and received unscheduled reoperation. The overall rate of unscheduled reoperation was 0.7%. A patient died within 30 days after the operation and the overall perioperative mortality was 0.4%. Conclusion: The surgical training of a high-volume center can ensure a high starting point in the initial stage and steady progress of pancreatic surgeons,to ensure the safety of pancreatic surgery.

Licorzine granules are common preparations for children zinc deficiency. Considering the long course of treatment, the taste of licorzine granules may become a main factor affecting medication adherence. To date there have been no taste evaluation research into licorzine granules yet. In this study, both sensory evaluation and electronic tongue method were utilized to optimize licorzine granules formulations, evaluate the tastes of licorzine, excipients, optimized formulation in vivo and in vitro. As the results show, bitterness and astringency are the main unpleasant tastes generating from licorzine. Xanthan gum is the main taste-masking excipient, lowering down the bitterness and astringency of licorzine by at least one grade. Good correlation exists between the results of sensory evaluation and electronic tongue method, and an integrated combination of the two helps to obtain objective and rational research conclusions. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.

In order to observe the effect of 0.3% deltamethrin long-lasting insecticidal mosquito nets on mosquitoes,laboratory and simulated field efficacy tests were carried out according to NY/T 1151.4-2012 standard.The results showed that the average knockdown rates of 0.3% deltamethrin long-lasting insecticidal mosquito nets against Culex pipiens pallens were 100%,96.49% and 93.94% in 1 h before washing,after 10 washes and 20 washes respectively.In the simulated field test,after 20 washes of 0.3% deltamethrin long-lasting insecticidal mosquito nets,the average knockdown rate of Cx.pipiens pallens was 93.68% at 12 hours and 93.68% at 24 hours.The results showed that 0.3% deltamethrin long-lasting insecticidal mosquito nets have an anti-mosquito effect in long periods.

Objective::Many studies have shown that blood glucose fluctuations (GFs) are more harmful to patients with diabetes mellitus (DM) than sustained hyperglycemia. However, the effect of GF on electrocardiogram (ECG) parameters and vulnerability to ventricular tachycardia/fibrillation (VT/VF) remains poorly characterized. This study aimed to assess the effect of GF on ECG parameters and induction of VT/VF in streptozotocin (STZ)-induced diabetic Sprague-Dawley rats.Methods::Male Sprague-Dawley rats were injected with STZ and randomly divided into 3 treatment groups: controlled STZ-induced diabetic rats (C-STZ) ( n = 10); uncontrolled STZ-induced diabetic rats (U-STZ) ( n = 10); and STZ-induced diabetic rats with glucose fluctuations (GF-STZ) ( n = 10). After 12 weeks, baseline ECG recordings were taken and a VT/VF test was performed with the administration of caffeine and dobutamine. Hematoxylin & eosin and masson staining were used to evaluate pathological cardiac changes after intervention. Results::No significant difference in heart rate, RR interval, P wave (duration and height), PR segment, PR interval, QRS wave duration, and T wave height was observed among the 3 groups ( P > 0.05). Compared with the C-STZ group, the U-STZ and GF-STZ groups both had a longer T wave duration ((62.41 ± 2.38) ms vs. (78.37 ± 4.64) ms and (96.06 ± 4.60) ms, P < 0.05), QT interval ((83.66 ± 2.31) ms vs. (101.75 ± 4.56) ms and (119.14 ± 4.88) ms, P < 0.05), and QTc interval ((77.45 ± 1.36) ms vs. (91.36 ± 3.49) ms and (104.55 ± 3.01) ms, P < 0.05), all of which were longest in the GF-STZ group ( P < 0.05). Additionally, the GF-STZ group had the highest VT/VF occurrence and duration and the highest arrhythmia score. Conclusion::This study revealed GF can significantly prolong the QT interval, QTc interval, and T wave duration, as well as increase vulnerability to VT/VF in rats, which may be an important electrophysiological mechanism of GF-related ventricular arrhythmia.

Objective: To trace and characterize the whole genome of SARS-CoV-2 of confirmed cases in the outbreak of COVID-19 on July 31, 2021 in Henan Province. Method: Genome-wide sequencing and comparative analysis were performed on positive nucleic acid samples of SARS-CoV-2 from 167 local cases related to the epidemic on July 31, 2021, to analyze the consistency and evolution of the whole genome sequence of virus. Results: Through high-throughput sequencing, a total of 106 cases of SARS-CoV-2 whole genome sequences were obtained. The results of genome analysis showed that the whole genome sequences of 106 cases belonged to the VOC/Delta variant strain (B.1.617.2 clade), and the whole genome sequences of 106 cases were shared with the genomes of 3 imported cases from Myanmar admitted to a hospital in Zhengzhou. On the basis of 45 nucleotide sites, 1-5 nucleotide variation sites were added, and the genome sequence was highly homologous. Conclusion: Combined with the comprehensive analysis of viral genomics, transmission path simulation experiments and epidemiology, it is determined that the local new epidemic in Henan Province is caused by imported cases in the nosocomial area, and the spillover has caused localized infection in the community. At the same time, it spills over to some provincial cities and results in localized clustered epidemics.
