Objective To investigate the effectiveness of intravenous thrombolytic therapy mode led by fast-track specialist nurses on patients with acute ischemic stroke(AIS).Methods This study involved 124 AIS patients who underwent intravenous thrombolytic therapy in the Department of Emergency of our hospital from March 2021 to February 2023.Among the patients,61 admitted between March 2021 and February 2022 received conventional AIS thrombolytic therapy were assigned to a control group.While the 63 patients who received AIS thrombolytic therapy under the specialist nurse-led intravenous thrombolytic therapy mode between March 2022 and February 2023 were assigned to an observation group.The two groups were compared in terms of the time from admission to completion of CT examination,time for signing the informed consent for thrombolytic therapy,door to needle time and percentage of DTN<60 minutes,as well as the post-thrombolysis scores according to the National Institute of Health Stroke Scale(NIHSS)and satisfaction to medical consultation.Results The observation group exhibited a significantly shorter time from admission to completion of CT examination,a shorter time for signing an informed consent for thrombolytic therapy,a shorter door to needle time and a higher percentage of DTN<60 minutes,all with significant difference in comparison with those in the control group.After thrombolysis,the NIHSS score of the observation group decreased more than that of the control group(P<0.05).The patients and their families in the observation group reported significantly higher satisfaction compared to those in the control group(both P<0.05).Conclusion The fast-track specialist nurse-led intravenous thrombolytic therapy mode demonstrates the superiority in reduction of the time from admission to completion of CT examination,time for signing an informed consent for thrombolytic therapy,door to needle time and the NIHSS scores,higher percentage of DTN<60 minutes as well as improvement of patient satisfaction.

Objective:To analyze the short-term clinical efficacy and safety of arsenic trioxide (ATO) combined with a modified N7 induction regimen in the treatment of children with high-risk neuroblastoma (NB).Methods:This study was a prospective, single-arm, multicenter phase Ⅱ clinical study. Sixty-seven high-risk NB children from eight units of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, Wuhan Children′s Hospital of Tongji Medical College of Huazhong University of Science and Technology, First Affiliated Hospital of Guangxi Medical University, Hainan General Hospital, Affiliated Hospital of Guangdong Medical University, Kunming Children′s Hospital, Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology, and Guangdong Provincial Agricultural Reclamation Center Hospital were enrolled from January 2019 to August 2023 and were treated with ATO combined with a modified N7 induction regimen. The efficacy and adverse effects at the end of induction chemotherapy were assessed and analyzed, and the differences in the clinical characteristics were further compared between the treatment-responsive and treatment-unresponsive groups by using the Fisher′s exact test.Results:Among 67 high-risk NB children, there were 40 males (60%) and 27 females (40%), with the age of disease onset of 3.5 (2.6, 4.8) years. Primary NB sites were mostly in retroperitoneum (including adrenal gland) (56/67, 84%) and the common metastases sites at initial diagnosis were distant lymph node in 25 cases (37%),bone in 48 cases (72%),bone marrow in 56 cases (84%) and intracalvarium in 3 cases (4%). MYCN gene amplification were detected in 28 cases (42%). At the end of induction, 33 cases (49%) achieved complete remission, 29 cases (43%) achieved partial remission, 1 case (1%) with stable disease, and 4 cases (6%) were assessed as progressive disease (PD). The objective remission rate was 93% (62/67) and the disease control rate was 94% (63/67). The percentage of central system metastases at the initial diagnosis was higher in the treatment-unresponsive group than in the treatment-responsive group (2/5 vs. 2% (1/62), P=0.013), whereas the difference in MYCN gene amplification was not statistically significant between two groups (3/5 vs.40% (25/62), P=0.786). Grade Ⅲ or higher adverse reactions during the induction chemotherapy period were myelosuppression occurred in 60 cases (90%), gastrointestinal symptoms occurred in 33 cases (49%), infections occurred in 20 cases (30%), hepatotoxicity occurred in 4 cases (6%), and cardiovascular toxicity occurred in 1 case (2%). There were no chemotherapy-related deaths. Conclusion:ATO combined with N7-modified induction regimen had a superiority in efficacy and safety, which deserved further promotion in clinical practice.

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.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To investigate the effects of Longmu Anshen prescription on microglia(MG)polarization in the medial prefrontal cortex(mPFC)and anxiety behavior of chronic restraint stress(CRS)mice.Methods:Forty-eight healthy male KM mice were randomly divided into normal group,paroxetine hydrochloride group and Longmu Anshen prescription high,middle and low dose groups.From the 15th day,after 30 minutes of CRS every day,the normal group and the model were given distilled water by gavage,the paroxetine hydrochloride group was given paroxetine hydrochloride(2.6 mg/kg)by gavage,and the traditional Chinese medicine group was given Longmu Anshen prescription at high,medium and low doses(4.16,2.08,1.04 g/kg)by gavage for 21 days.The changes of anxiety behavior in mice were evaluated by light-dark boxes experiment and elevated plus maze;ELISA was used to detect IL-1β,IL-6,TNF-α and IL-10 levels;protein expression of inducible nitric oxide synthase(iNOS)and arginase-1(Arg-1)in mice mPFC tissue were detected by Western blot;mRNA expression of ionized calcium binding adaptor molecule-1(Iba-1),iNOS and Arg-1 in mice mPFC tissue were detected by RT-PCR;the protein expression of Iba-1 in mice hippocampal tissue was detected by immuno-histochemistry(IHC).Results:Compared with normal group,the residence time in the light boxes,the number of times of shuttle between the light-dark boxes,the percentage of times of entering the open arm(OE%)and the percentage of time spent in the open arm(OT%)of mice in model group were significantly reduced(P<0.01);moreover,in the mPFC tissue of the model group mice,the protein and mRNA expressions of Iba-1 and iNOS were significantly increased(P<0.01),and the levels of IL-1β,IL-6 and TNF-α were significantly increased(P<0.01),while the protein and mRNA expressions of Arg-1 were significantly decreased(P<0.01),and the level of IL-10 was significantly decreased(P<0.01).Compared with model group,the residence time in the light boxes,the number of shuttles between the light-dark boxes,the OE%and OT%of mice in the paroxetine hydrochloride group and the high and medium dose groups of Longmu Anshen prescription were significantly increased(P<0.01);the expression levels of Iba-1 and iNOS protein and mRNA in mPFC tissue were significantly decreased(P<0.05,P<0.01),and the levels of IL-1β,IL-6 and TNF-α were significantly decreased(P<0.01),while the expression levels of Arg-1 protein and mRNA were significantly increased(P<0.01).IL-10 level was significantly increased(P<0.01).Conclusion:Longmu Anshen prescription can inhibit the activation of MG in mPFC tissues of CRS mice and may reduce nerve inflammation and increase the level of anti-inflammatory cytokines by regulating the polarization phenotype of M1/M2,thereby ameliorate CRS-induced anxiety behavior.

Objective To investigate the relationship between the changes of serum human surfactant pro-tein D(SP-D)and vascular cell adhesion molecule-1(sVCAM-1)levels and postoperative fracture healing and short-term prognosis in patients with traumatic rib fractures.Methods A total of 102 patients with traumatic rib fractures who were treated in Banan Hospital Affiliated to Chongqing Medical University from January 2020 to December 2021 were selected as the research objects.After 8 months of treatment,the healing status of the patients was analyzed and divided into non-healing group(21 cases)and healing group(81 cases).Ac-cording to the pulmonary contusion,the patients were divided into pulmonary contusion group(19 cases)and non-pulmonary contusion group(83 cases).The serum levels of SP-D and sVCAM-1 were compared between the healing group and the non-healing group,and between the pulmonary contusion group and the non-pulmo-nary contusion group.The relationship between the changes of serum SP-D and sVCAM-1 levels and postop-erative fracture healing and short-term prognosis in patients with traumatic rib fractures were studied.Results The levels of SP-D and sVCAM-1 in the healing group were lower than those in the non-healing group(P＜0.05).The levels of SP-D and sVCAM-1 in the non-pulmonary contusion group were lower than those in the pulmonary contusion group(P＜0.05).Serum SP-D and sVCAM-1 levels were independent risk factors for postoperative fracture healing and short-term prognosis.Conclusion The changes of serum SP-D and sVCAM-1 levels in patients with traumatic rib fractures are related to fracture healing and short-term prognosis,which can be used as an important reference for prognosis evaluation.

Objective To investigate the application value of multiple audiological testing methods in the audi-ological diagnosis of children with no response at maximum output intensity of auditory brainstem response(ABR).Methods We retrospectively studied the clinical data of 69 cases(138 ears)of children with no ABR response with maximum intensity,aged 42 days to 5 years old,with an average of 1 year and 6 months.The tympanogram showed type-A or positive single peak,and acoustic reflex was absent.Imaging examination showed no malformation of the inner ear.All 69 children underwent ABR,cochlear microphonic potential(CM),distortion product otoacoustic e-missions(DPOAE),and auditory steady-state response(ASSR)tests.Results Among 69 cases(138 ears),8 ca-ses(11.59％)recorded CM in 16 ears,of which 10 ears(7.25％)recorded DPOAE.The ASSR response thresh-olds at 0.5,1,2,and 4 kHz were 83.2±13.1,82.9±13.0,75.3±12.4,and 63.1±9.1 dB nHL,respectively.Combined with other examination results,these subjects were diagnosed with auditory neuropathy.The CM and DPOAE responses of the remaining 61 cases(122 ears)were absent,and the extraction rates of ASSR at 0.5,1,2,and 4 kHz were 82.3％,81.9％,76.9％,and 60.2％,respectively.Among them,20 ears of ASSR were absent at all frequencies,and 102 ears had responses in at least one frequency.The response thresholds of ASSR at 0.5,1,2,and 4 kHz were 93.2±6.1,99.8±7.0,105.4±5.4,108.2±9.8 dB nHL,respectively.These subjects were diagnosed with profound sensorineural hearing loss.Conclusion For children with no ABR response at maximum output intensity,while CM and/or DPOAE responses are present and ASSR frequency response thresholds are low-er than those with sensorineural hearing loss are helpful in the diagnosis of auditory neuropathy.Neither CM nor DPOAE response is helpful in the diagnosis of profound sensorineural hearing loss,and ASSR testing is helpful in e-valuating residual hearing.

Objective:To investigate the characteristics and differences in clinical efficacy of proprioceptive neuromuscular facilitation(PNF)and lower limb robotics in improving lower limb motor function,walking speed,and auto-matic balance function in stroke patients. Method:Seventy-two stroke patients with hemiplegia who met the criteria were randomly assigned to the con-ventional group(n=25),PNF group(n=24),and lower limb robotics group(n=23).The treatment lasted for 4 weeks.Before and after treatment,the Fugl-Meyer assessment lower extremity scale(FMA-LE),10m maxi-mum walking speed test(MWS),and neuro com balance manager system were used to evaluate lower limb movement function,walking speed and automatic balance function. Result:After 4 weeks of treatment,the FMA-LE score of PNF group was significantly better than that of conventional group(P＜0.05)and lower limb robotics group(P-0.001),the MWS score in the lower limb ro-botics group was significantly better than that in the conventional group(P＜0.05)and the PNF group(P=0.001),and the MWS score in the PNF group was significantly better than that in the conventional group(P＜0.05).The lower limb robotics group showed significantly better scores in the reaction time,movement veloci-ty,endpoint travel distance,maximum excursions and directional control index score than the conventional group(P＜0.05)and the PNF group(P＜0.05),while the directional control index score in the PNF group was significantly better than that in the conventional group(P=0.049). Conclusion:Manual PNF therapy and lower limb robotics training have their own clinical efficacy in stroke patients,with PNF technique being more effective in improving lower limb motor function,while lower limb robotics have an advantage in automatic balance function and walking speed.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.
