Objective:To evaluate the therapeutic effect of ultrasound-guided sphenopalatine ganglion block on allergic rhinitis.Methods:A total of 719 patients with allergic rhinitis admitted to Changsha Hospital of Traditional Chinese Medicine (Changsha Eighth Hospital) from January 2022 to December 2023 were selected as the study subjects. Among them, 483 patients who received sublingual desensitization treatment in the otolaryngology outpatient department were selected as the control group, and 236 patients who received ultrasound-guided sphenopalatine ganglion block treatment in the pain outpatient department were selected as the observation group. All patients underwent Nasal Provocation Test (NPT) scores and Quality of Life Scale (QLS) scores before and after treatment to evaluate the treatment efficacy of both groups and record adverse reactions.Results:The NPT scores of both groups of patients improved after treatment at 1, 3, and 6 months compared to before treatment (all P<0.05); After 1 and 3 months of treatment, the NPT score of the observation group was lower than that of the control group, and the difference was statistically significant (all P<0.05); After 6 months of treatment, there was no statistically significant difference in NPT scores and treatment efficacy between the two groups of patients (all P>0.05). The QLSscores of both groups of patients improved after treatment at 1, 3, and 6 months compared to before treatment (all P<0.05); After 1 and 3 months of treatment, the QLS score of the observation group was lower than that of the control group, and the difference was statistically significant (all P<0.05); After 6 months of treatment, there was no statistically significant difference in QLS scores between the two groups of patients ( P>0.05). During the treatment process, some patients experienced brief facial numbness, pain, and other discomforts, which all resolved on their own within a short period of time. Conclusions:Ultrasound guided sphenopalatine ganglion block has a good therapeutic effect on allergic rhinitis and can quickly improve the quality of life of patients.

Objective:To investigate the risk factors of pathological complete response(pCR)after neoadjuvant therapy for locally advanced gastric cancer(LAGC)and assess the value of gastric tumor markers for predicting pCR in LAGC patients.Methods:We retrospectively ana-lyzed the clinical and pathological characteristics of 213 patients who underwent radical gastrectomy and gastric tumor marker analysis after neoadjuvant therapy at The Chinse PLA General Hospital First Medical Center,between January 2020 and April 2024(20 and 193 cases in the pCR and non-pCR groups,respectively).The interrelationships among pCR,tumor markers,and clinicopathological features were compared,and independent risk factors for pCR were analyzed.A nomogram was constructed to predict the pCR.Results:Among 213 patients,20(9.4% )achieved pCR.Univariate analysis showed that age(P=0.067),tumor bed diameter(P<0.001),gastrin-17 levels(P=0.005),CA72-4 levels(P=0.073),pepsinogen ratio(P=0.024),and neoadjuvant immunotherapy(P=0.022)were strongly associated with pCR in LAGC pa-tients.Multivariate analysis showed that neoadjuvant immunotherapy,CA72-4 levels<2.5 U/mL,gastrin-17 levels<1.48 pmol/L,and tumor bed diameter<2.85 cm were independent predictive factors for pCR in LAGC patients(P<0.05).These indicators were incorporated into a nomogram prediction model;an receiver operating characteristic curve(ROC)was plotted with an AUC(95% CI)of 0.863(0.785-0.942).The calibration and decision curves suggested that the nomogram was well calibrated and had a good net benefit.Conclusions:Gastric tumor markers can effectively predict pCR after neoadjuvant therapy in LAGC patients.Our nomogram showed a good predictive ability for pCR.Thus,our findings can serve as a useful reference for clinical decision making for LAGC patients.

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 investigate the relationship between cognitive impairment and sleep parameters in acute ischemic stroke patients with obstructive sleep apnea(OSA).Methods A total of 343 patients with acute ischemic stroke and OSA were selected.The cognitive function was assessed using the simple mental state examination scale(MMSE).Patients were divided into the stroke with OSA and cognitive impairment group(MMSE＜27 points,n=119)and the stroke with OSA without cognitive impairment group(MMSE≥27 points,n=224).General data,TOAST etiological classification and distribution of cerebral infarction lesions were collected.The intelligent sleep monitoring system was used to calculate apnea hypopnea index(AHI)and evaluate OSA.Objective sleep monitoring parameters were collected at night.Sleep monitoring was conducted within 24 h of admission and continuous monitoring for≥3 nights.Continuous monitoring duration≥7 h every night to obtain night sleep structure parameters.Multifactor Logistics regression was used to analyze the relationship between cognitive impairment and sleep parameters in stroke patients with OSA.Results Compared with the stroke with OSA without cognitive impairment group,the proportion of age,diabetes history and HHcy history,the proportion of patients with infarct lesions located in frontal,temporal,parietal,occipital,thalamus,basal ganglia,brainstem and hemioval center increased in the stroke with OSA and cognitive impairment group,and the number of years of education decreased,the number of waking times,the proportion of light sleep and AHI increased,the nighttime sleep efficiency and deep sleep period decreased(P＜0.05).Logistics regression analysis showed that after controlling for years of education,age and other interference factors,nighttime sleep efficiency and AHI were strongly associated with cognitive impairment in acute ischemic stroke patients with OSA(P＜0.05).The increased nighttime sleep efficiency was protective factor for cognitive impairment,and increased AHI was risk factor for cognitive impairment.Conclusion Cognitive impairment in acute ischemic stroke patients with OSA is closely related to sleep parameters,in which the increased sleep efficiency at night is a protective factor for cognitive impairment,and the increased AHI is a risk factor.

GI (GIGANTEA) is one of the output key genes for circadian clock in the plant. The JrGI gene was cloned and its expression in different tissues was analyzed to facilitate the functional research of JrGI. RT-PCR (reverse transcription-polymerase chain reaction) was used to clone JrGI gene in present study. This gene was then analyzed by bioinformatics, subcellular localization and gene expression. The coding sequence (CDS) full length of JrGI gene was 3 516 bp, encoding 1 171 amino acids with a molecular mass of 128.60 kDa and a theoretical isoelectric point of 6.13. It was a hydrophilic protein. Phylogenetic analysis showed that JrGI of 'Xinxin 2' was highly homologous to GI of Populus euphratica. The result of subcellular localization showed that JrGI protein was located in nucleus. The JrGI, JrCO and JrFT genes in female flower buds undifferentiated and early differentiated of 'Xinxin 2' were analyzed by RT-qPCR (real-time quantitative PCR). The results showed that the expression of JrGI, JrCO and JrFT genes were the highest on morphological differentiation, implying the temporal and special regulation of JrGI in the differential process of female flower buds of'Xinxin 2'. In addition, RT-qPCR analysis showed that JrGI gene was expressed in all tissues examined, whereas the expression level in leaves was the highest. It is suggested that JrGI gene plays a key role in the development of walnut leaves.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.
