ObjectiveTo observe the prevention and control effect of processed Polygonatum cyrtonema on depression induced by chronic unpredictable mild stress (CUMS) in female rats. MethodsForty rats were assigned into control, model, and low-, medium-, and high-dose processed P. cyrtonema groups according to the random number table method, with 8 rats in each group. The rat model of depression was established with the CUMS method. The body mass, open field test, forced swimming test, Morris water maze test, levels of neurotransmitters [dopamine (DA), 5-hydroxytryptamine (5-TH), and acetylcholine (ACh)], serum levels of sex hormones [gonadotropin-releasing hormone(GnRH), testosterone (T), and estradiol (E2)] and inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-10], and mRNA and protein levels of factors in the brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TRKB)/cAMP-response element binding protein (CREB) pathway were employed to evaluate the effect of processed P. cyrtonema on the CUMS-induced depression in female rats. ResultsThe body mass, open field test results, and forced swimming test results showed that the rat model of depression was successfully established. The comparison of behaviors, neurotransmitters, sex hormones, inflammatory factors, and neural pathways among groups showed that processed P. cyrtonema had different effects of preventing the development of depression in female rats. SPSS 25 was used for statistical analysis of error and significance. T test was conducted between groups. Each treatment group showed significant therapeutic effect compared with the model group (P<0.05). Processed P. cyrtonema elevated the level of 5-TH (P<0.01) and lowered the levels of DA and ACh (P<0.01) in the brain tissue of female rats. In addition, it reduced the serum levels of GnRH, T, E2, TNF-α, and IL-6 (P<0.05) and up-regulated the mRNA levels of BDNF and TRKB in the rat brain. ConclusionProcessed P. cyrtonema has a non-hyperactive preventive effect on CUMS-induced depression in rats, which provides a theoretical basis for the development of processed P. cyrtonema as a functional food product.

ObjectiveTo observe the clinical effectiveness and potential mechanism of combined tongue three-needle acupuncture and acupoint application on Lianquan (CV 23) for patients with dysphagia after ischemic stroke. MethodsA prospective study was conducted on 160 patients with post-stroke dysphagia, who were randomly divided into a treatment group and a control group, with 80 cases in each group. The control group received conventional rehabilitation training, while the treatment group received tongue three-needle acupuncture combined with acupoint application on Lianquan (CV 23) on the basis of conventional rehabilitation training, for 4 weeks in both groups. We compared the clinical effectivenss of both groups after treatment, and assessed the swallowing function including videofluoroscopic swallowing study (VFSS), standardized swallowing assessment (SSA) and functional oral intake scale (FIOS), swallowing contrast test including hyoid maximum displacement (HmaxD), pharyngeal transit time (PTT), and upper esophageal sphincter (UES) opening, surface electromyography (sEMG) test including maximum amplitude and swallowing duration as well as swallowing quality of life questionnaire (SWAL-QOL) score of the patients in both groups before treatment, after 2 weeks and 4 weeks of treatment, respectively. ResultsThe total effective rate in treatment group was 82.50% (66/80), significantly higher than 66.25% (53/80) in control group (P<0.05). The VFSS, and FOIS scores, UES opening rate and HmaxD, sEMG maximal amplitude values, and SWAL-QOL scores were increased in both groups after 2 weeks and 4 weeks of treatment compared with the values before treatment (P<0.05), while SSA scores, PTT, and swallowing duration were decreased compared within group before treatment (P<0.05). VFSS and FOIS scores, UES opening rate and HmaxD, sEMG maximal amplitude values, and SWAL-QOL scores after 2 and 4 weeks of treatment in the treatment group were higher (P<0.05), while SSA scores, PTT, and swallowing duration were lower (P<0.05) than those in the control group at the same time. ConclusionCombined tongue three-needle acupuncture and acupoint application on Lianquan (CV 23) for patients with dysphagia after ischemic stroke can significantly improve swallowing activities, and its mechanism of action may be related to the improvement of the contraction ability and coordination of swallowing-related muscle groups.

ObjectiveTo study the characteristics of imprinting template of flavonoid clusters in four Chinese medicines attributed to the lung meridian, and to establish an in vitro experimental approach for the study of the attribution of Chinese medicines to the lung meridian. MethodBased on 13 Chinese medicines, including Xanthii Fructus, Houttuyniae Herba, Fagopyri Dibotryis Rhizoma, Belamcandae Rhizoma and so on, which only belong to the lung meridian in Chinese Materia Medica(the 13th Five-Year planning textbook of general higher education), we identified four representative Chinese medicines, namely Houttuyniae Herba, Fagopyri Dibotryis Rhizoma, Belamcandae Rhizoma and Mori Cortex, and set up their fingerprints by high performance liquid chromatography(HPLC) and calculated the molecular connectivity indices of various components in the four Chinese medicines, the similarity to their mean value was calculated by included angle cosine method, so as to establish the quantitative relationship of construction versus imprinting ability, and to determine the order of each component in the lung meridian. A total of 7 reference substances, including chlorogenic acid, rutin, quercetin, isoquercitrin, hyperoside, epicatechin, and iridin, were selected to validate the overall conformational relationships of flavonoids of the model, as well as its predictive ability. ResultHouttuyniae Herba, Fagopyri Dibotryis Rhizoma, Belamcandae Rhizoma and Mori Cortex contained a total of 437 chemical components with an average molecular connectivity index similarity of 0.995 6. The four Chinese medicines contained a total of 204 flavonoids with an average molecular connectivity index similarity of 0.978 0, which was second only to the alkaloids with 0.985 1. The retention time(tR) of the 7 reference substances showed a good conformational relationship with the similarity of the molecular connectivity index(tR=831.4×S-790.3, r=0.861 4, P<0.01), which was applicable to the in vitro attribution study of the position, similarity, and relative similarity with tR of the cluster of 98.04% of flavonoids. Accordingly, the 1st position was kuwanon D, with a similarity of molecular connectivity index of 0.987 7 and a tR of 30.88 min, the 200th position was chlorogenic acid, with a similarity of molecular connectivity index of 0.958 2 and a tR of 6.36 min. The total first-order moment of the four Chinese medicines calculated by total statistical moment method of fingerprint was 24.26 min, ranked 21, which could characterize 99.19% of the whole, and the total first-order moment of the total peak area of the 7 reference substances in the four Chinese medicines was 20.00 min, with a rank of 46, which could characterize 98.68% of the whole. ConclusionFlavonoid clusters are suitable probes for the characterization of imprinting template for the study of the lung meridian, which can be established a quantitative imprinting method for meridian tropism of Chinese medicines in vitro.

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 study the effect of long non⁃coding RNA (LncRNA) HAGLR on the expression of NODlike receptor pyrin domain⁃associated protein 3 ( NLRP3 ) inflammasome and fracture healing in tibial fracture (TF) mice and to explore the mechanism .
Methods :
First , HAGLR in osteoblast MC3T3 ⁃E1 was silenced by in vitro . Cell viability was detected by CCK⁃8 assay , cell apoptosis was detected by TUNEL assay , and the expressions of bone alkaline phosphatase (BALP) and osteocalcin were detected by qPCR . Western blot assay was used to detect the expressions of RUNX2 , phosphorylated RUNX2 ( p ⁃RUNX2 ) , NLRP3 , cysteine aspartic protease 1 (Caspase1) , apoptosis⁃associated spot⁃like protein ( ASC) and interleukin⁃1β . TF mouse models were established by tibial fracture operation in mice . HAGLR was overexpressed in the model mice , and RUNX2 was silenced or an inflammatory body inhibitor MCC950 was added on the basis of overexpression of HAGLR . The expressions of HAGLR and RUNX2 were detected by qPCR , and the expressions of insulin⁃like growth factor (IGF⁃1) were detected by Western blot . microCT was used to measure the volume of mouse callus (MBV) and the total tibial wet weight .
Results :
The apoptosis rate of MC3T3 ⁃E1 cells increased and the expression levels of RUNX2 ,p⁃RUNX2 , BALP and osteocalcin decreased ( P < 0. 05 ) . The expressions of NLRP3 , Caspase1 , ASC and IL⁃1β increased ( P <0. 05) . Compared with healthy tissue , the expressions of HAGLR and RUNX2 in TF mice decreased . Overexpression of HAGLR promoted the expressions of HAGLR and RUNX2 in TF mice , and increased the expression of MBV and tibia wet weight and IGF⁃1 (P < 0. 05) . Silencing RUNX2 on the basis of overexpression of HAGLR resulted in decreased expression of MBV , tibial wet weight and IGF⁃1 in TF mice (P < 0. 05) . However , the addition of NLRP3 inflammasome inhibitor MCC950 on top of the overexpression of HAGLR resulted in increased expressions of MBV , full⁃length tibia wet weight and IGF⁃1 (P < 0. 05) .
Conclusion
LncRNA HAGLR promotes the healing of tibial fractures by activating RUNX2 and inhibiting NLRP3 inflammasome .
