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.

The chemical constituents from the fruits of Morinda citrifolia were systematically explored by chromatographic fractionation methods including silica gel, octadecylsilyl(ODS) gel, Sephadex LH-20 gel, and preparative high performance liquid chromatography(pre-HPLC).

Objective To study the effect of atmospheric particulate exposure on the expression of key molecules of Nrf2 signaling pathway involved in oxidative stress and inflammatory response factors in myocardium of rats fed with high-fat and high-glucose diet. Methods A total of 48 SD male rats were randomly divided into control group (CC group), high-fat and high-glucose diet group (HC group), atmospheric particulates group (CP group) and atmospheric particulates plus high-fat and high-glucose diet group (HP group), with 12 rats in each group.Rats were fed in individual ventilated cages (IVC).The CC and HC groups were placed in IVCs equipped with the atmospheric particulate filter, however, the CP and HP groups without the atmospheric particulate filter to make the air composition similar to the outdoor.A total of 24 rats were sacrificed for acquiring myocardial tissue after 3 and 6 months of exposure.The mRNA expression of Nrf2, HO-1, NQO1, VCAM-1 and MCP-1 were measured using RT-qPCR and the protein expression of VCAM-1, MCP-1 detected using western blot. Results The mRNA expression levels of Nrf2, HO-1, NQO1, VCAM-1 and MCP-1 and the protein expression levels of VCAM-1 and MCP-1 in HC, CP and HP groups were higher than CC group (P < 0.05).The mRNA expression levels of Nrf2, HO-1, NQO1, VCAM-1, MCP-1 and the protein expression levels of VCAM-1, MCP-1 in the HP group were higher than HC and CP groups (P < 0.05).The mRNA expression levels of Nrf2 in CP and HP groups after 6 months of exposure were lower than that at 3 months (P < 0.05). Conclusion The exposure of atmospheric particles, high-fat and high-glucose and their combination diets could cause myocardial tissue inflammatory responses, and activate Nrf2 signaling pathways to protect against myocardial damage.

Osteosarcoma is a rare primary malignancy of bone that is prone to early metastasis. Resection surgery and chemotherapeutic regimens are current standard treatments for osteosarcoma. However, the long-term survival rate of patients with osteosarcoma is low due to a high risk of metastasis. Hence, a new approach is urgently needed to improve the treatment of osteosarcoma. Compared with chemotherapy, natural active constituents isolated from herbs exhibit less adverse effects and better anti-tumor effects. This study aimed to summarize the anticancer effects of constituents of herbs on the progression and metastasis of osteosarcoma cells. It showed that many constituents of herbs inhibited osteosarcoma by targeting proliferation, matrix metalloproteinases, integrin and cadherin, and angiogenesis. The findings might be beneficial for the development of new drugs and treatment strategies.

We investigated the microRNA172 (miR172)-mediated regulatory network for the perception of changes in external and endogenous signals to identify a universally applicable floral regulation system in ornamental plants, manipulation of which could be economically beneficial. Transgenic gloxinia plants, in which miR172 was either overexpressed or suppressed, were generated using Agrobacterium-mediated transformation. They were used to study the effect of altering the expression of this miRNA on time of flowering and to identify its mRNA target. Early or late flowering was observed in transgenic plants in which miR172 was overexpressed or suppressed, respectively. A full-length complementary DNA (cDNA) of gloxinia (Sinningia speciosa) APETALA2-like (SsAP2-like) was identified as a target of miR172. The altered expression levels of miR172 caused up- or down-regulation of SsAP2-like during flower development, which affected the time of flowering. Quantitative real-time reverse transcription PCR analysis of different gloxinia tissues revealed that the accumulation of SsAP2-like was negatively correlated with the expression of miR172a, whereas the expression pattern of miR172a was negatively correlated with that of miR156a. Our results suggest that transgenic manipulation of miR172 could be used as a universal strategy for regulating time of flowering in ornamental plants.

Objective To study the influence of isoniazid on lymphocyte factor expression and macrophage function of rats.Methods Healthy male SD rats were randomly divided into three groups,which was treated for one month,three months and withdrawal for one month after treated for three months,and each group was randomly divided into isoniazid group and control group.The isoniazid groups were ig with isoniazid at dose of 120 mg/kg every other day and control groups were fed on normal saline.At the corresponding time points,the level of interleukin-12 (IL-12) and interferon-γ (IFN-γ) was detected with ELISA method,detected serum lysozyme content by agar plate method,and Comori method was used for the detection of acid phosphatase levels in peritoneal fluid.Results At all the time points,levels of IL-12,IFN-γ and lysozyme in isoniazid group were not significantly different compared with control group.There were statistically significant differences in acid phosphatase between isoniazid group and control group after treated for one month (P ＜ 0.05),but the significant differences disappeared at the next two time points.Conclusion Isoniazid of 120 mg/kg may have no obvious influence on the immune function of rat.We don't detect the immune injury.

OBJECTIVETo survey the reporting quality of traditional Chinese medicine (TCM) case reports published in recent years and understand the common problems. The assessment results would lay the foundation for the development of recommendations for case report in Chinese medicine.

METHODSThis survey determined the reporting quality of cases with Chinese herbal decoction, Chinese proprietary medicine, acupuncture, moxibustion and other traditional therapies published in 20 core medical journals of China by searching the China Academic Journals Full-text Database from 2006 to 2010. Fifty survey items in 16 domains were used to determine the reporting quality. One point was assigned to each item (Yes=1 point; No=0 point), and total score was 50 points. The domain of treatment was assessed independently, ranging from 2 to 9 items for different TCM interventions.

RESULTSThe total of 1,858 case reports, covering 3,417 cases were included to analyze from 13 out of 20 core medical journals of China. There were 74.8% of them did not identify the nature of study in title, while 73.9% did not comprise an abstract. Incomplete reporting was found in discussions/ comment, and only 38.9% had made recommendations or take-away messages. Figures and tables were infrequently used. Three cases cited the full names of patients, but without declaring that any consent was obtained. Over 90% reported the symptoms and signs of TCM, and characteristics on tongue and pulse, but less than 50% did mention other medical history and diagnostic rationale. More than 90% treatments of the included cases were herbal decoction, with clear reporting on the ingredients and dosages. However, the reporting rate of the dosages of each ingredient was just 48.4%. Almost none reported the quality control of crude herbs, manufacturers and lot numbers of herbal proprietary medicine. Besides, advices and precautions on diet, emotions and living were rare to be illustrated.

CONCLUSIONSystematic reporting recommendations are urged to develop for improving the contents and format of case reports in TCM.

Case reports are valuable clinical evidence in traditional Chinese medicine (TCM). However, the general reporting quality is suboptimal. A working group comprising 20 members was set up to develop systematic recommendations on case report in Chinese medicine (CARC). The working group (CARC group) developed a primary checklist based on reviewing the general reporting quality of case reports in TCM and thorough internal discussion. Two-round consensus process had been carried out among clinical experts, evidence-based medicine methodologists, medical journal editors and clinical practitioners with designated questionnaire embedded with the primary checklist. In total, 118 participants from 17 provinces of China and Korea completed the questionnaires. Their feedback was analyzed and discussed by the CARC group. The checklist was amended accordingly, and the final version, comprising 16-item, is presented here. Under the framework of CARC recommendations, the reporting quality of case reports in TCM can be improved.

The effects of diclazuril on the bursa of Fabricius (BF) structure and secretory IgA (SIgA) expression in chickens infected with Eimeria tenella were examined. The morphology of the BF was observed by hematoxylin and eosin staining, while ultrastructural changes were monitored by transmission electron microscopy. E. tenella infection caused the BF cell volumes to decrease, irregularly arranged, as well as, enlargement of the intercellular space. Diclazuril treatment alleviated the physical signs of damages associated with E. tenella infection. The SIgA expression in BF was analyzed by immunohistochemistry technique. The SIgA expression increased significantly by 350.4% (P<0.01) after E. tenella infection compared to the normal control group. With the treatment of diclazuril, the SIgA was relatively fewer in the cortex, and the expression level was significantly decreased by 46.7% (P<0.01) compared with the infected and untreated group. In conclusion, E. tenella infection in chickens induced obvious harmful changes in BF morphological structure and stimulated the expression of SIgA in the BF. Diclazuril treatment effectively alleviated the morphological changes. This result demonstrates a method to develop an immunological strategy in coccidiosis control.
