OBJECTIVE: To explore the main components and potential mechanisms of Sangqi Qingxuan Liquid in the treatment of arterial vascular endothelial cells (AVECs) injury in hypertension through network pharmacology. METHODS: Traditional Chinese Medicine Systems Pharmacology and Analysis Platform (TCMSP) and Traditional Chinese Medicine Integrated Database (TCMID) were used to screen the active components of Sangqi Qingxuan Liquid (SQQX), which met the oral utilization rate and drug similarity criteria. An active component-target network was constructed using Cytoscape 3.6 software. A protein-protein interaction (PPI) network of targets associated with SQQX treatment for hypertension was constructed using the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database. The Metascape database was used to perform enrichment analysis of gene ontology biological functions and MSigDB pathway enrichment analysis of proteins in the PPI network. Further analysis of the main components of SQQX was performed using UPLC-MS. Based on the results of network pharmacology, the mechanism of SQQX to improve the injury of AVECs in hypertension was verified through lentiviral transfection by Wnt/ β -catenin signaling pathway. AVECs induced by angiotensin II (Ang II ) was used to establish a model of endothelial function injury in hypertension. Cell viability, intracellular nitric oxide content, malonaldehyde content, and superoxide dismutase activity were measured to determine the optimal induction conditions. The optimal intervention conditions for SQQX were determined based on cell viability, cellular DNA activity, and the gradient method. The cells were further divided into blank, model, overexpression lentivirus negative control, overexpression lentivirus, overexpression lentivirus + SQQX intervention (2.47 mg/mL, 12 h), inhibition lentivirus negative control, inhibition lentivirus, and inhibition lentivirus + SQQX intervention (2.47 mg/mL, 12 h) groups. Finally, quantitative real-time PCR and Western blotting were performed to analyze the molecular mechanisms of SQQX in the Wnt/ β -catenin signaling pathway. RESULTS: The main SQQX components were betaine, buddleoside, and chlorogenic acid, in descending order. Network pharmacology analysis screened 12 pathways associated with the hypertensive vascular endothelium. The results showed that 1 µ mol/L for 12 h was the optimal condition for Ang II to induce AVECs injury, and 2.47 mg/mL SQQX intervention for 12 h was the optimal condition for treating AVECs injury. In the experimental validation based on the interaction network of the Wnt/ β -catenin signaling pathway, SQQX significantly decreased the expressions of β -catenin, Smad2, peroxisome proliferator-activated receptors (PPARs), endothelial nitric oxide synthase (eNOS), and endothelin-1 (ET-1) caused by the β -catenin overexpression lentivirus (P<0.05 or P<0.01). The function of vascular endothelial cells can be improved by the β -catenin inhibition lentivirus, and no obvious changes were observed after further intervention with SQQX. CONCLUSION SQQX may protect against AVECs injury by regulating the Wnt/β -catenin signaling pathway.

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 compare the clinical efficacy between the combined therapy of fire needling and cupping, and western medication on herpes zoster of acute stage, as well as the effects on Th17 and Treg cells and inflammatory factors, i.e. IL-10 and IL-17 in the peripheral blood. METHODS: Eighty patients with herpes zoster of acute stage were randomly divided into a combined therapy (fire needling plus cupping) group and a western medication group, 40 cases in each one. In the combined therapy group, the pricking and scattering techniques with fire needle were used at ashi points and Jiaji (EX-B 2) corresponding to the affected spinal segments; afterwards, cupping therapy was delivered. The combined treatment was given once daily. In the western medication group, valaciclovir hydrochloride tablet and vitamin B₁ tablet were administered orally. The duration of treatment in each group was 10 days. Before each treatment from day 1 to day 10 and on day 11 , the score of symptoms and physical signs was observed in the two groups separately. Before each treatment from day 1 to day 10 and on day 11, 30, 60, the score of visual analogue scale (VAS) and skin lesion indexes were observed in the two groups. On day 60, the incidence of postherpetic neuralgia was recorded in the two groups. The levels of Th17 and Treg cells, Th17/Treg ratio in the peripheral blood, as well as serum levels of IL-10 and IL-17 were detected before and after treatment in the two groups. The clinical efficacy was compared between the two groups. RESULTS: From day 6 to day 10 during treatment and on day 11, the scores of symptoms and physical signs in the combined therapy group were lower than those of the western medication group (P<0.05, P<0.01). On day 3, day 6 to day 10 during treatment and day 11, day 30, VAS scores in the combined therapy group were lower than those of the western medication group (P<0.05, P<0.01). On day 60, the incidence of postherpetic neuralgia in the combined therapy group was lower compared with that in the western medication group (P<0.05). The blister arresting time and scabbing time in the combined therapy group were shorter than those of the western medication group (P<0.05). After treatment, the level of Th17, and Th17/Treg ratio in the peripheral blood, as well as the serum levels of IL-10 and IL-17 were all lower in comparison with those in the western medication group (P<0.05). The curative and remarkably effective rate was 82.5% (33/40) in the combined therapy group, higher than 62.5% (25/40) in the western medication group (P<0.05). CONCLUSION The early application of fire needling combined with cupping therapy can effectively treat herpes zoster of acute stage, relieve pain, and reduce the incidence of postherpetic neuralgia, which may be related to reducing the levels of Th17 and Treg cells, and Th17/Treg ratio in the peripheral blood, as well as the serum levels of IL-10 and IL-17 so that the cellular immune balance is modulated.

To investigate the effect of Polygonum multiflorum-Andrographis paniculata intercropping system on rhizosphere soil actinomycetes of P. multiflorum, the community structure and diversity of soil actinomycetes were studied by using the original soil as the control group and the rhizosphere soil actinomycetes communities of P. multiflorum under monoculture and intercropping systems as the experimental group. In this study 655 221 effective sequences were obtained with an average length of 408 bp. OTU coverage and rarefaction curve showed that the sequencing could represent the real situation of soil actinomycetes. According to the results of alpha diversity analysis, the diversity soil actinomycetes varied as follows: original soil>intercropping soil>monoculture soil. The soil actinomycetes community structure and the relative abundance of dominant genera were significantly changed by both monoculture and intercropping, especially monoculture. OTU clustering and PCA analysis of soil samples showed that all the soil samples were divided into three distinct groups and the original soil was more similar to intercropping soil. In addition, intercropping increased the relative abundance of some beneficial actinomyces, such as Kitasatospora and Mycobacterium, which was beneficial to maintain soil health and reduce the occurrence of soil-borne diseases. The results show that, P. multiflorum-A. paniculata intercropping reduced the change of community structure and the decrease of diversity of soil actinomycetes caused by P. multiflorum monoculture, and made the actinomycete community in rhizosphere soil of P. multiflorum close to the original soil.

Objective: To search for an optimal strategy for the treatment of penile and scrotal gangrene by analyzing the clinical effect of vacuum sealing drainage (VSD) as an adjuvant treatment on this disease. METHODS: We retrospectively analyzed the clinical data about 4 cases of penile and scrotal gangrene treated by VSD as an adjuvant treatment from January 2015 to June 2016. The 4 patients all underwent early extensive and radical debridement of gangrene of the scrotum and penis and received intravenous injection of two broad-spectrum antibiotics, followed by VSD for wound drainage and irrigation. RESULTS: Adequate wound drainage was achieved in all the 4 cases, the gangrene range rapidly localized and testicular necrosis avoided. The wound surface healed satisfactorily after cleansing and suturing. The patients were followed up for 3 months after discharged from the hospital and none experienced recurrence. CONCLUSIONS VSD combined with early adequate debridement can effectively localize the gangrene range, significantly reduce the frequency of changing dressings and shorten the hospitalization time of the patient, and therefore is a very effective adjuvant treatment of penile and scrotal gangrene.

It is of vital significance to conduct active post-marketing surveillance of Chinese medicine, as an active response to laws, rules and guidelines issued by the China food and drug administration. The standards for technological specifications based on expert consensus have been drafted. These will provide technological support in evaluating adverse drug reactions (ADRs) or adverse drug events (ADEs). The technological specifications for post-marketing surveillance focus on two surveillance designs; one is a large sample registry study to explore general population ADR/ADE characteristics, the other is a nested case-control study to explore the characteristic and mechanisms of ADRs.

UNLABELLEDThis study is conducted to explore an effective culture method for supporting the embryo development. The cattle fetal ear fibroblasts and the goat fetal ear fibroblasts are transplanted into the enucleated cattle oocytes separately by oocyte intraplasmic nuclear injection method to construct bovine cloned embryos and goat-bovine cloned embryos. The embryos are first cultivated in modified charles rosenkrans 2 amino acid medium (mCR2aa) and modified synthetic oviduct fluid medium (mSOF) separately. Then BSA (8 mg/mL) or FBS (10%) can be added to mSOF according to the different culture period. The supplements and orders, added during the first three days and after three days are as follow: BSA and BSA, BSA and FBS, FBS and BSA, FBS and FBS. On the basis of the cleavage rate, 8/16-cell rate, blastocysts rate and total cell number of blastocysts, the best culture way can be screened out.

RESULTFirst, cleavage rate, 8/16-cell rate, blastocysts rate and total cell number of blastocysts, cultivated in mSOF solution are all higher than those cultivated in mCR2aa( P < 0.05). Second, the cleavage rate and 8/16-cell rate, adding BSA and FBS into mSOF, are in turn 79.8% +/- 7.1%, 49.7% +/- 3.5%, 21.5% +/- 1.8%, and 115.2 +/- 4.3 in bovine cloned embryo, and 40.1% +/- 6.3%, 29.2% +/- 2.0%, 13.4% +/- 2.1% and 100.1 +/- 3.0 in goat-bovine cloned embryo, which are significant higher than other culture groups (P < 0.05).

CONCLUSIONThe goat-bovine cloned embryo can be cultivated by the optimized culture measure of bovine cloned embryo. The best culture ways of bovine cloned embryo and goat-bovine cloned embryo are all to use mSOF supplemented BSA in the first three days and then use mSOF supplemented FBS in the next five days.
