Objective To investigate the role of transcranial magnetic stimulation(TMS)in the modulation of abnormal functional status and damage characteristics of key brain regions in adult patients with anisometropic amblyopia via the resting-state functional magnetic resonance imaging(rs-fMRI)technique.Methods Single(left)eyes of 20 adult refractive amblyopia patients were included in this study and randomly divided into a surgical group[Implantable Collamer Lens(ICL)surgery]and a TMS combined group(TMS treatment on top of the surgical group),with 10 patients in each group.In both groups,the visual a-cuity of patients was examined before and after treatment via international standard visual acuity charts to evaluate the therapeu-tic effect.Moreover,patients in both groups underwent an fMRI examination once before and after treatment,and local coher-ence(ReHo),amplitude at low frequency(ALFF),and ratio amplitude at low frequency(fALFF)algorithms were used to char-acterize the functional state and response characteristics of the brain regions in the acquired f MRI images.Results Compared with that before treatment,the visual acuity of patients in both groups significantly improved after treatment and was signifi-cantly greater than the pretreatment corrected visual acuity(P＜0.05).Compared with that in the two groups after treatment,the improvement in visual acuity in the TMS combined group was greater than that in the surgical group(P＜0.05).There was no difference in the ReHo or fALFF values before and after treatment between the TMS combined group and surgical group.Compared with those before treatment,the ipsilateral frontal ALFF values were increased in the surgical group after treatment,and the ipsilateral cerebellar ALFF values were decreased in the TMS combined group.Compared with those in the surgical group,the ipsilateral frontal lobe and superior frontal gyrus ReHo values decreased,the contralateral temporal lobe and superior temporal gyrus ALFF values decreased,and the contralateral occipital lobe and cuneiform lobe fALFF values increased after treatment in the TMS combined group(all P＜0.05).Conclusion The improvement in spontaneous brain activity in pa-tients with anisometropic amblyopia in the surgical group and in the TMS combined group was significant.ICL implantation may act by activating the ipsilateral frontal lobe,ICL implantation in combination with TMS may act by improving cerebellar func-tion,increasing the excitability of the contralateral occipital and cuneate lobes,modulating neuronal activity in the adjacent cor-tex of the occipital lobe and in the other visually related cortices(ipsilateral frontal and contralateral temporal lobes),and correc-ting the difference in excitability between the two eyes of the patients.and correcting the excitability differences between the pa-tient's two eyes.

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 allergen map of patients with allergic diseases in northwest China, to investigate the distribution characteristics of serum specific Immunoglobulin E (sIgE) in different ages, genders, diseases and the sensitization patterns of allergens. Methods: This study is a cross-sectional study, a total of 1 161 patients with confirmed respiratory allergic diseases were selected retrospectively from outpatient or inpatient department of Gansu Provincial People's Hospital, Gansu Provincial Maternity and Child Care Hospital, General Hospital of Ningxia Medical University, Yinchuan Maternal and Child Health Care Hospital, Xijing Hospital, Air Force Military Medical University and Tumor Hospital of Inner Mongolia Autonomous Region from June 2019 to October 2022. HAIKE ALLEOS 2000 fluorescent magnetic particle chemiluminescence method was used to quantify their serum for 12 inhaled allergen-specific IgE. Chi square test or Fisher's exact test were used for comparison between count data groups (Bonferroni correction was used for further pairwise comparison in multiple groups, two-sided P<0.05/3=0.017 considered that the difference was statistically significant). Pearson correlation analysis was used for correlation of continuous numerical variables. Results: The positive detection rate of sIgE in 1 161 patients was 66.8%(776/1 161). The three highest positive rate of inhaled allergen were mugwort(599/1 161, 51.6%), French chrysanthemum(565/1 161, 48.7%) and dandelion(412/1 161, 35.5%). In different age groups, the highest positive rate of sIgE was 7-18 age group(379/513, 73.9%) while the lowest positive rate was 4-6 age group(222/370, 60.0%), the difference between groups was statistically significant(χ²=21.177, P<0.001). The sensitization peak of mugwort, French chrysanthemum, plantain, timothy, birch, dermatophagoides pteronyssinus, dermatophagoides farinae, cat epithelium, dog epithelium and German cockroach appeared in 7-18 age group. In different disease groups, the highest positive rate of sIgE was allergic rhinitis with asthma group (500/717, 69.7%) while the lowest positive rate was asthma group (76/144, 52.8%), the difference between groups was statistically significant(χ²=15.563, P<0.001). In different gender groups, the positive rate of sIgE in male (503/711, 70.7%) was higher than in female (273/450, 60.7%), the difference between groups was statistically significant(χ²=12.630, P<0.001). The multiple-sensitization rate was 86.9%(674/776) and the double-sensitization rate was 16.8%(130/776) in sIgE positive patients. Pearson correlation results showed that there was an extremely strong correlation between dandelion and French chrysanthemum(r=0.93,P<0.001). There was a strong correlation between mugwort and French chrysanthemum(r=0.64,P<0.001). In the co-sensitization analysis, the number of patients sensitized by mugwort, French chrysanthemum, dandelion, plantain and timothy accounted for 25.2%(170/674)of the total number of multiple sensitization. The number of patients sensitized by mugwort, French chrysanthemum and dandelion accounted for 58.3%(393/674)of the total number of multiple sensitization. The number of patients sensitized by mugwort, French chrysanthemum, dandelion and plantain accounted for 35.6%(240/674) of the total number of multiple sensitization. Conclusion: Mugwort, French chrysanthemum, dandelion are the major inhaled allergens in northwest China. The positive rate of sIgE was different in different ages, diseases and genders. The multiple-sensitization rate of allergen was high and there was a certain positive correlation between pollen allergen-specific IgE pairwise, suggesting that there may exist co-sensitization or cross-reactions among allergens.

Objective:To study the effect and mechanism of mitochondria-targeted antioxidant peptide SS-31 on sepsis-induced acute kidney injury (AKI).Methods:Sixty adult male C57BL/6 mice were randomly divided into four groups according to the random number table method: sham group (10 mice), positive control group (10 mice), sepsis model group (20 mice), and SS-31 peptide group (20 mice). The sepsis-induced AKI mouse model was reproduced by cecal ligation and puncture (CLP). The sham group only received laparotomy. SS-31 peptide (5 mg/kg) was intraperitoneally injected in SS-31 peptide group and positive control group 30 minutes after the operation, while an equivalent amount of normal saline was given in sham group and sepsis model group for 7 days. The blood samples were collected 24 hours after the operation from orbit, and the serum was collected to test the serum creatinine (SCr) and blood urea nitrogen (BUN). The mice were sacrificed 7 days after surgery. The kidney tissues were collected to observe the pathologic structure changes under the hematoxylin-eosin (HE) staining by light microscope. And the mitochondrial ultrastructure was checked under the transmission electron microscope. Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method (TUNEL). The expression level of peroxisome proliferator-activated receptorγ coactivator-1α (PGC-1α), adenosine monophosphate-activated protein kinase (AMPK), and cleaved caspase-3 protein were tested by Western blotting.Results:Compared with sham group, the levels of SCr and BUN were significantly increased in sepsis model group [SCr (μmol/L): 93.12±11.80 vs. 32.94±3.37, BUN (mmol/L): 41.36±6.48 vs. 9.49±3.58, both P<0.05]. The expression levels of AMPK, PGC-1α and cleaved caspase-3 protein increased (AMPK/β-actin: 0.30±0.02 vs. 0.12±0.01, PGC-1α/β-actin: 0.38±0.03 vs. 0.16±0.02, cleaved caspase-3/β-actin: 0.20±0.01 vs. 0.11±0.02, all P<0.05). HE staining showed that inflammatory cell was infiltrated, glomerular basement membrane was exposed and vacuole-like transparent casts were found in the lumen. Mitochondria were damaged under electron microscope with swelling, ridge disappearance and ruptured membranes, with increasing of apoptotic cells [cells: 24.00 (18.75, 31.00) vs. 2.00 (0.72, 3.25) , P<0.05]. Meanwhile, compared with sepsis model group, the levels of SCr, BUN and the expressions of AMPK, PGC-1α, cleaved caspase-3 protein were significantly decreased in the SS-31 peptide group [SCr (μmol/L): 71.33±10.14 vs. 93.12±11.80, BUN (mmol/L): 27.00±5.52 vs. 41.36±6.48, AMPK/β-actin: 0.23±0.01 vs. 0.30±0.02, PGC-1α/β-actin: 0.27±0.02 vs. 0.38±0.03, cleaved caspase-3/β-actin: 0.13±0.01 vs. 0.20±0.01, all P < 0.05]. HE staining showed that cell swelling reduced, the mitochondrial structure was intact, the ridge swelling was also reduced, and the membrane structure was relatively intact, the number of apoptotic cells was significantly reduced [cells: 13.00 (9.00, 16.50) vs. 24.00 (18.75, 31.00) , P<0.05]. Conclusion:The protective effect of SS-31 peptide on organ dysfunction induced by sepsis-induced AKI is related to maintaining mitochondrial homeostasis and inhibiting cell apoptosis.

Objective: “Same treatment for different diseases” is a unique treatment strategy in traditional Chinese medicine. Two kinds of malignant respiratory diseases endanger human health-chronic obstructive pulmonary disease (COPD) and lung cancer. Citrus Grandis Exocarpium (Huajuhong in Chinese, HJH), a famous herbal, is always applied by Chinese medicine practitioners to dispersion the lung to resolve phlegm based on “syndrome differentiation and treatment” theory. However, the common mechanism for HJH's treatment of COPD and lung cancer is not clear. Methods: In this study, based on network pharmacology and molecular docking technology, the common mechanism of HJH in the treatment of COPD and lung cancer was studied. The active ingredients and related targets of HJH were integrated from TCMSP, BATMAN-TAM, STP, and Pubchem databases. The standard names of these targets were united by UniProt database. Targets of COPD and lung cancer were enriched through GeneCards, NCBI (Gene), Therapeutic Target Database, and DisGeNET (v7.0) databases. Then the intersection targets of HJH and diseases were obtained. The STRING network and the Cytoscape 3.7.2 were used to construct PPI network, the DAVID database was used to perform GO and KEGG analysis. Then Cytoscape 3.6.1 was used to build “ingredient-target-signal pathway” network. Finally, AutoDock 1.5.6 software was used to perform molecular docking of key proteins and molecules. Results: Eleven active ingredients in HJH were obtained by searching the database, corresponding to 184 HJH-COPD-lung cancer targets intersection. The results of biological network analysis showed that naringenin, the active component in HJH, could mainly act on target proteins such as AKT1, EGFR. Then through positive regulation of vasoconstriction and other biological processes, naringenin could regulate estrogen signaling pathway, VEGF signaling pathway, HIF-1 signaling pathway, ErbB signaling pathway, PI3K-Akt signaling pathway to play an important role in the treatment of both COPD and lung cancer. Conclusion: Network pharmacology was employed to systematically investigate the active ingredients and targets of HJH in treatment of COPD and lung cancer. And then, the common pharmacodynamic network of HJH for the two malignant respiratory diseases was firstly described. Furthermore, naringenin was proved to strongly bind with AKT1 and EGFR. It may provide the scientific basis for understanding the “Same treatment for different diseases” strategy in traditional Chinese medicine and inspirit subsequent drug discovery for COPD, lung cancer and other malignant lung diseases.
