Background: Salvia miltiorrhiza Bunge, commonly known as “Danshen” in China due to the distinctive red color of its roots, is one of the most widely used traditional Chinese medicines. It is cultivated in various regions across China, and environmental differences among these regions can affect the secondary metabolites of plants, thereby influencing the quality of S. miltiorrhiza. In recent years, increasing demand for S. miltiorrhiza has exacerbated the problem of origin fraud. Therefore, ensuring the authenticity of its geographical origin is crucial for the sustainable development of the industry. Objective: The red coloration of S. miltiorrhiza is closely associated with the content of its primary active compounds, particularly tanshinones. Therefore, both its internal chemical composition and external color characteristics serve as key indicators for quality assessment. This study utilized hyperspectral imaging technology to evaluate its potential in classifying the geographical origin of S. miltiorrhiza. Methods: Spectral data reflecting the internal chemical properties of S. miltiorrhiza were integrated with color information representing its external features through 3 levels of data fusion. These fused datasets were then combined with deep learning algorithms to achieve accurate origin classification. Results: The results demonstrated that the Transformer model combined with soft-voting decision-level fusion achieved the highest classification accuracy of 98.72% by integrating image color and short-wave infrared spectral data. Conclusion: This study demonstrates that integrating hyperspectral imaging spectral data with color information provides a reliable and innovative approach for verifying the authenticity and traceability of S. miltiorrhiza.

Chronic obstructive pulmonary disease （COPD） is one of the most common chronic diseases of the respiratory system in the clinic. The disease has a long course and is difficult to cure， which seriously threatens human health. Airway mucus hypersecretion （AMH） is an independent risk factor for COPD and has a significant impact on the development and prognosis of the disease. The review finds that the abnormal proliferation of goblet cells and the excessive secretion of mucin are the direct causes of AMH. The pathogenesis of AMH may be closely related to the inhalation of heterogeneous particles， airway inflammation， the imbalance of mucin/water salt ratio， and the regulation of related signaling pathways. Traditional Chinese medicine （TCM） believes that AMH of COPD belongs to the category of lung distension with phlegm-fluid retention syndrome， and the disease is mainly treated from phlegm on the basis of lung distension. This article summarizes the relevant research in the field of TCM in recent years and finds that the single TCM that effectively intervened AMH of COPD is mainly phlegm-resolving TCM， and the main active ingredients of TCM are flavonoids， terpenoids， phenols， and alkaloids. The main TCM compounds are mainly designed to remove heat-phlegm， warmly resolve cold-phlegm， dry dampness to eliminate phlegm， invigorate Qi， promote blood circulation and dispel phlegm， and invigorate lung， spleen， and kidney. Its mechanism of action may be direct inhibition or indirect inhibition of airway epithelial goblet cell metaplasia and mucin expression by inhibiting airway inflammation， regulating aquaporins to correct the imbalance of mucin/water salt ratio， and regulating signaling pathways， so as to reduce mucus oversecretion in COPD. However， there are still some problems. For example， the research mainly focuses on TCM compounds instead of the single TCM or its effective components. The research on the mechanism of action is not thorough enough， and the research results are not interoperable. The clinical transformation rate of basic research is insufficient. This article systematically reviews the research status of AMH in the treatment of COPD with TCM and puts forward some thoughts on the existing problems， so as to provide a reference for clinical rational medication and in-depth research.

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 evaluate the effect of sonication, repeated freeze-thaw cycles, calcium salt solution and their combination on the content of related growth factors (GFs) released by platelet rich plasma (PRP). METHODS: Twenty PRPs from healthy blood donors were divided into 9 groups, including sonication group, freeze-thaw group, calcium gluconate group, calcium chloride group, sonication + calcium gluconate group, sonication + calcium chloride group, freeze-thaw + calcium gluconate group, freeze-thaw + calcium chloride group, and sonication + freeze-thaw group. After PRP activated by above 9 methods, the content of transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), and platelet-derived growth factor-BB (PDGF-BB) were detected by ELISA. RESULTS: The platelet concentration of the samples was (966.7±202.6)×10⁹/L. The content of TGF-β1 in sonication + freeze-thaw group was the highest, while the lowest was in freeze-thaw group. The content of VEGF in freeze-thaw + calcium chloride group was the highest, while the lowest was in calcium gluconate group. The content of PDGF-BB in sonication + freeze-thaw group was the highest, while the lowest was in calcium gluconate group. There was no significant differences in the three GFs between calcium gluconate group and calcium chloride group. CONCLUSION Among the 9 activated methods of PRP, there is no difference between two calcium salt solutions. And the combination of repeated freeze-thaw cycles and sonication may be the best treatment method to promote PRP to release GFs, while calcium gluconate is the weakest way.

OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

Objective To investigate the genetic variation and epidemiological characteristics of influenza B virus in Xinxiang to provide policy basis for local influenza vaccination. Methods The influenza surveillance data in Xinxiang from January 2012 to February 2019 was analyzed. 23 isolated influenza B virus were randomly selected for hemagglutinin (HA) and neuraminidase (NA) gene sequencing. Sequence alignment was conducted by using DNAman software and phylogenetic tree analysis was conducted using Neighbor-Joining method. Results Yamagata (BY) and Victoria (BV) strains of influenza B virus circulated alternately every other year in Xinxiang, mainly among people aged 0-15 years (91.4%). The dominant influenza B lineages from 2015 to 2016 and from 2017 to 2018 did not match the corresponding trivalent vaccine strain of the year. The HA phylogenetic tree revealed that 87.5% (7/8) of BV strains coexisted with the vaccine strain in one branch, while 88.98% (8/9) of BY strains from 2013 to 2015 were not in the same branch as the corresponding vaccine strain, with 5 epitope site mutions N116K, S150L, N165Y, D196N and N202S. No drug-resistant site mutation was identified in the NA gene. A total of 6 intra-lineage reassortants were identified. Conclusions The influenza B lineage in the trivalent vaccine recommended by WHO did not match the dominant circulating B lineage of Xinxiang in some epidemic year. Therefore, quadrivalent vaccines are recommended to use in susceptible population, especially under the age of 15. In addition, there are large variations in HA gene of the epidemic BY strain compared with the corresponding vaccine. Then, a vaccine more sutable for the epidemic strains in China is expected to be developed.

Objective To illustrate the semiological characteristics of the three sub-types within the broad bilateral asymmetric tonic seizures (BATS),summarize their predictive values on lateralization and localization of seizure onset zone (SOZ),and analyze the difference between BATS and asymmetrical tonic limb posturing (ATLP).Methods A retrospective review of 385 patients who underwent stereotactic electrode implantation in the Sanbo Brain Hospital,Capital Medical University from September 2011 to May 2018 was performed.As long as there was a clinical epileptic seizure in the presence of BATS or ATLP,the patients were classified into the corresponding groups.Postoperative prognosis was assessed using Engel's grading criteria for a follow-up of no less than six months.Seizure descriptions were based on the classification of epileptic seizures introduced by Lüiders,which used arrows to connect the symptoms in chronological order.Results There was no statistically significant difference between the classic BATS and bilateral proximal tonic seizure in terms of whether it could be an independent seizure,as the onset and end of the seizure,with version and generalized tonic-clonic seizure (P＞0.05).Compared with the ATLP,except for whether it could be an independent seizure (P=1.000) and onset before versive seizure (P=0.068),the BATS showed significantly different semiological features (P＜0.05).The classic BATS and secondary motor area epilepsy had a 100.0％ predictive accuracy on the lateralization of SOZ.In the patients with broad BATS,the SOZ distribution was more extensive,but it was rare in the orbitofrontal gyrus,frontal pole and mesial temporal lobe.Compared with the bilateral proximal tonic seizures from the other regions,those originated from supplementary somatosensory motor area and its adjacent areas were rare and showed no statistically significant difference (0/8 vs 40.0％ (18/45),x2=3.226,P=0.072) but a low trend.The predictive value of BATS on lateralization of SOZ was higher than that of ATLP (84.9％ (45/53) vs 57.1％ (24/42),x2=9.086,P=0.003),and BATS was less originated from temporal lobe than ATLP (3.8％ (2/53) vs 23.8％ (10/42),x2=8.523,P=0.004).Conclusion Different from ATLP,the broad BATS are characterized by tonic proximal upper limb posturing,and have a higher predictive value on lateralization and localization of SOZ.

AIM:To investigate the expression of fatty-acid amide hydrolase(FAAH)in paraventricular nu-cleus(PVN)and its contribution to renal sympathetic nerve activity in rats with chronic heart failure(CHF).METH-ODS:A rat model of CHF was established by ligation of the left coronary artery to induce acute myocardial infarction. Eight weeks after ischemia,the rat model of CHF was identified by echocardiogram and histopathological observation.The plasma level of norepinephrine(NE)was detected by ELISA.The protein expression levels of FAAH in the PVN were de-termined by Western blot.The N-arachidonoylethanolamide(AEA)generation in PVN was analyzed by high-performance liquid chromatography.After microinjection of AEA,PF3845(an FAAH inhibitor)or rAAV2-FAAH shRNA virus in PVN, the sympathetic drive indexes were recorded in different experiment groups.RESULTS: Compared with the rats in sham group,the cardiac function and AEA concentration in PVN were significantly reduced, while the plasma NE level and FAAH expression in PVN were obviously increased in the CHF rats(P<0.05).After microinjecion of PF3845, AEA or rAAV2-FAAH shRNA virus in PVN, the sympathetic drive indexes were decreased significantly and the cardiac function were improved in the CHF rats.CONCLUSION:Upregulated FAAH expression in PVN may result in sympathoexcitation in the rat with CHF.
