ObjectiveTo explore the molecular mechanism implicated in the treatment of primary myelofibrosis (PMF) using Chinese medicinal herbs (CMH) by bioinformatics and molecular dynamics. MethodsData mining was performed to find the high-frequency CMH in treating PMF between the year of 1985 and 2024 by searching CNKI, Chinese Science and Technology Journal Database (CCD), and China Academic Journal Database (CSPD). TCMSP, SwissTargetPrediction and related reports were used to collect the main active ingredients of high-frequency CMH and their targets. The PMF datasets GSE44426 and GSE124281 were downloaded from GEO database, and R software was used for data normalization and differentially expressed genes (DEGs) screening. Key module hub genes were obtained by weighted gene co-expression network analysis (WGCNA) analysis. The common intersection genes of active ingredient targets, DEGs and key module hub genes of CMH were selected, and the target network was generated using Cytoscape 3.9.2 software. The core target network was generated by topological analysis, while key pathways were selected by GO and KEGG pathway enrichment analysis, and protein interaction relationships were obtained from the String database, so as to construct drug-ingredient-target network and protein interaction network (PPI) relationship diagrams. Discovery Studio 2020 software was used to perform molecular docking, and the GROMACS program was used to perform molecular dynamics simulation. ResultsA total of 21 prescriptions were collected involving 121 herbs. There were 9 herbs with a frequency ≥10 times, which were Danshen (Radix et Rhizoma Salviae Miltiorrhizae), Huangqi (Radix Astragali), Baizhu (Rhizoma Atractylodis Macrocephalae), Danggui (Radix Angelicae Sinensis), Dangshen (Radix Codonopsis), Gancao (Radix et Rhizoma Glycyrrhizae), Baishao (Radix Paeoniae Alba), Fuling (Poria) and Shudihuang (Radix Rehmanniae Praeparata) from high- to low-frequency. A total of 98 active ingredients and 1125 potential targets were obtained from 9 high-frequency CMH. GSE44426 and GSE124281 data sets screened out 24 gene samples, including 14 of the healthy control group and 10 of the PMF group, and identified 319 DEGs between the two groups, including 122 up-regulated genes and 197 down-regulated genes. WGCNA screened out 24 co-expression module genes and found that the five modules closely related to the onset of PMF were MEpink, MEdarkred, MEblack, MEgrey, and MEturquoise, involving 7112 key module hub genes. The GO and KEGG enrichment analyses indicated that lipids and the atherosclerosis pathways were mainly involved in the mechanism of above high-frequency CMH in treating PMF, which included six hub protein targets: HSP90AA1, HSP90AB1, SRC, MAPK1, IL1B and IL10. From the drug-ingredient-target network, seven active ingredients of CMH targeting at these six hub targets were found, including verbascoside, verbascos isoflavone, kaempferol, luteolin, naringenin, quercetin and pachymic acid. The molecular docking and molecular dynamics analyses showed that the key CMH were Shudihuang, Huangqi, Baishao, Danshen, Gancao and Fuling, and among the seven active ingredients, calycosin had the highest binding affinity with HSP90AB1. ConclusionThe main CMH for the treatment of PMF may be Shudihuang, Huangqi, Baishao, Danshen, Gancao and Fuling, and the active ingredients include verbascoside, verbascos isoflavones, kaempferol, luteolin, naringenin, quercetin and pachymic acid. The relevant targets are HSP90AA1, HSP90AB1, SRC, MAPK1, IL-10, and IL-1β, and the most critical pathways are lipid and atherosclerosis pathways.

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 observe the effects of electroacupuncture(EA)combined with Western medication on lower-limb motor function and blood circulation in patients with cerebral infarction-induced hemiplegia in the acute stage. Methods:One hundred eligible patients with acute ischemic stroke accompanied by lower-limb motor dysfunction were allocated to an observation group and a control group using the random number table method,with 50 cases in each group.The control group received routine Western medications for treatment,and the observation group received additional EA intervention.After 2-week and 4-week treatments,the improvement of lower-limb motor function was assessed using the Fugl-Meyer assessment scale for lower extremity(FMA-LE),and changes in the peak blood flow velocities of the posterior tibial(PT)and dorsalis pedis(DP)arteries on the affected side were detected using Doppler. Results:Three cases dropped out during the study,so there were 48 cases in the observation group and 49 in the control group collected for statistical analysis.The FMA-LE score and the peak blood flow velocities of PT and DP arteries increased after 2-week and 4-week treatments in both groups compared with the pre-treatment baseline(P<0.05).After 2-week treatments,the FMA-LE score and the peak blood flow velocities of PT and DP arteries showed no significant differences between the two groups(P>0.05).After 4-week treatments,compared with the control group,the FMA-LE score was higher(P<0.05),and the peak blood flow velocities of PT and DP arteries on the affected side were larger in the observation group(P<0.05). Conclusion:EA combined with Western medication can significantly improve the motor function and blood flow velocity of the affected lower limb in patients with acute cerebral infarction accompanied by hemiplegia.

Objective: Total neoadjuvant therapy has been used to improve tumor responses and prevent distant metastases in patients with locally advanced rectal cancer (LARC). Patients with complete clinical responses (cCR) then have the option of choosing a watch and wait (W&W) strategy and organ preservation. It has recently been shown that hypofractionated radiotherapy has better synergistic effects with PD-1/PD-L1 inhibitors than does conventionally fractionated radiotherapy, increasing the sensitivity of microsatellite stable (MSS) colorectal cancer to immunotherapy. Thus, in this trial we aimed to determine whether total neoadjuvant therapy comprising short-course radiotherapy (SCRT) combined with a PD-1 inhibitor improves the degree of tumor regression in patients with LARC. Methods: TORCH is a prospective, multicenter, randomized, phase II trial (TORCH Registration No. NCT04518280). Patients with LARC (T3-4/N+M0, distance from anus ≤10 cm) are eligible and are randomly assigned to consolidation or induction arms. Those in the consolidation arm receive SCRT (25Gy/5 Fx), followed by six cycles of toripalimab plus capecitabine and oxaliplatin (ToriCAPOX). Those in the induction arm receive two cycles of ToriCAPOX, then undergo SCRT, followed by four cycles of ToriCAPOX. Patients in both groups undergo total mesorectal excision (TME) or can choose a W&W strategy if cCR has been achieved. The primary endpoint is the complete response rate (CR, pathological complete response [pCR] plus continuous cCR for more than 1 year). The secondary endpoints include rates of Grade 3-4 acute adverse effects (AEs) etc. Results: Up to 30 September 2022, 62 patients attending our center were enrolled (Consolidation arm: 34, Induction arm:28). Their median age was 53 (27-69) years. Fifty-nine of them had MSS/pMMR type cancer (95.2%), and only three MSI-H/dMMR. Additionally, 55 patients (88.7%) had Stage III disease. The following important characteristics were distributed as follows: lower location (≤5 cm from anus, 48/62, 77.4%), deeper invasion by primary lesion (cT4 7/62, 11.3%; mesorectal fascia involved 17/62, 27.4%), and high risk of distant metastasis (cN2 26/62, 41.9%; EMVI+ 11/62, 17.7%). All 62 patients completed the SCRT and at least five cycles of ToriCAPOX, 52/62 (83.9%) completing six cycles of ToriCAPOX. Finally, 29 patients achieved cCR (46.8%, 29/62), 18 of whom decided to adopt a W&W strategy. TME was performed on 32 patients. Pathological examination showed 18 had achieved pCR, four TRG 1, and 10 TRG 2-3. The three patients with MSI-H disease all achieved cCR. One of these patients was found to have pCR after surgery whereas the other two adopted a W&W strategy. Thus, the pCR and CR rates were 56.2% (18/32) and 58.1% (36/62), respectively. The TRG 0-1 rate was 68.8% (22/32). The most common non-hematologic AEs were poor appetite (49/60, 81.7%), numbness (49/60, 81.7%), nausea (47/60, 78.3%) and asthenia (43/60, 71.7%); two patients did not complete this survey. The most common hematologic AEs were thrombocytopenia (48/62, 77.4%), anemia (47/62, 75.8%), leukopenia/neutropenia (44/62, 71.0%) and high transaminase (39/62, 62.9%). The main Grade III-IV AE was thrombocytopenia (22/62, 35.5%), with three patients (3/62, 4.8%) having Grade IV thrombocytopenia. No Grade V AEs were noted. Conclusions: SCRT-based total neoadjuvant therapy combined with toripalimab can achieve a surprisingly good CR rate in patients with LARC and thus has the potential to offer new treatment options for organ preservation in patients with MSS and lower-location rectal cancer. Meanwhile, the preliminary findings of a single center show good tolerability, the main Grade III-IV AE being thrombocytopenia. The significant efficacy and long-term prognostic benefit need to be determined by further follow-up.

Objective:To observe the clinical efficacy of acupuncture plus point application in managing pain after thoracoscopic radical lung cancer surgery(TRLCS). Methods:A total of 120 patients undergoing TRLCS were randomized into a treatment group and a control group,with 60 cases in each group.Both groups received patient-controlled intravenous analgesia(PCIA)to relieve postoperative wound pain.The control group did not receive any other interventions.The treatment group started acupuncture treatments 4 h after the surgery with point application between two acupuncture sessions;the acupuncture treatment was conducted 4,24,48,and 72 h after the surgery.At the above 4 time points,the visual analog scale(VAS)score and additional PCIA drug consumption were recorded.The 5-hydroxytryptamine(5-HT)content in the peripheral blood was determined 4 h and 72 h after the surgery. Results:The treatment group was superior to the control group in comparing the total effective rate(P<0.05).After the intervention,the VAS score decreased in both groups(P<0.05);the VAS score presented different decreasing patterns at each time point in the two groups,and the score dropped more significantly in the treatment group than in the control group(P<0.05).The total PICA drug consumption varied in the two groups after the surgery;the additional analgesic consumption was notably smaller in the treatment group than in the control group(P<0.05).The decrease in the 5-HT content in the peripheral blood also varied in the two groups;the peripheral blood 5-HT content was significantly lower in the treatment group than in the control group(P<0.05). Conclusion:Acupuncture plus point application can significantly relieve wound pain after TRLCS.

ObjectiveTo explore the molecular mechanism of "transmission between the lung and brain" of influenza based on Janus kinase 1/signal transducer and activator of transcription 1(JAK1/STAT1) signaling pathway and further investigate the intervention effect of Maxing Shigantang (MXSGT). MethodA total of 100 SPF BALB/c mice were randomly divided into a normal group,a model group,an oseltamivir group (21.63 mg·kg-1·d-1),an antiviral granules group(3.9 g·kg-1·d-1), and an MXSGT group(6.05 g·kg-1·d-1), with 20 mice in each group. The pneumonia model was induced in mice except for those in the normal group by intranasal infection of influenza A virus(IAV). Twenty-four hours after modeling,mice were treated with corresponding drugs, while those in the normal group and the model group received the same amount of normal saline by gavage, once a day for 3 and 7 days. The pathological changes in the lung and brain were observed by hematoxylin-eosin(HE)staining. The mRNA expression of IAV nucleoprotein(NP),JAK1, and STAT1 in the lung and brain was detected by real-time quantitative polymerase chain reaction(Real-time PCR), and the protein expression of JAK1 and STAT1 in the lung and brain was detected by Western blot. Immunohistochemical method was used to detect the expression of phosphorylated(p)-STAT1 in the lung and brain tissues, and enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of interleukin-1β(IL-1β) and interleukin-10(IL-10). ResultCompared with the normal group, the model group showed obvious pathological changes in the lung tissues and cerebral cortex, increased relative mRNA expression of IAV NP in the lung (P<0.01), elevated mRNA and protein expression of JAK1 and STAT1 in the lung and brain tissues (P<0.05,P<0.01),up-regulated expression level of p-STAT1 in lung tissues and cerebral cortex (P<0.05,P<0.01), and increased serum level of IL-1β (P<0.05). Compared with the model group, the MXSGT group showed alleviated pathological damage to lung tissues and cerebral cortex, decreased relative mRNA expression of IAV NP in lung tissues(P<0.01),reduced mRNA and protein expression levels of JAK1 and STAT1 in lung tissues and brain tissues(P<0.05,P<0.01), and increased serum level of IL-10(P<0.01). ConclusionThe abnormal activation of the JAK1-STAT1 signaling pathway may be one of the molecular mechanisms of "transmission between the lung and brain" of influenza. As an effective compound prescription against the influenza virus,MXSGT can alleviate the pathological damage of brain tissues in mice infected with IAV by regulating the level of cytokines mediated by this pathway.
