In recent years, the literature showed that Yiqi Yangyin and Huoxue Huayu method (benefiting qi and nourishing yin, promoting blood circulation to remove blood stasis) in treating diabetic complications has achieved a satisfactory effect. This article made a summary on the method of Yiqi Yangyin and Huoxue Huayu from theoretical, clinical, and laboratory aspects.

Objective To explore the mechanism of Didang Qigui Recipe on preventing diabetes. Methods Ten female rats were set randomly as normal group, and others 70 were injected with STZ (60 mg/kg) to establish the diabetic model. After the model was established, 50 model rats were randomly divided into five groups:the model group, Didang Qigui Recipe group, the gliclazide group, Didang Qigui Recipe high-dose group, Didang Qigui Recipe and gliclazide group, with 10 rats in each group. All groups were given a gavage with related medicine. With treatment being given respectively, eight weeks later, contents of IL-1βand IL–2 in serum were detected by ELISA and structure of pancreatic β cells was observed by immunohistochemistry and microscope. Results Compared with the model group, the contents of IL-1βand IL-2 in serum of rats decreased in treatment groups, especially in Didang Qigui Recipe group and Didang Qigui and gliclazide group (P<0.05). The degree of apoptosis in pancreaticβcells, especially in the above two groups, has been less affected than other groups (P<0.05). Conclusion Didang Qigui Recipe has preventive and therapeutic effects on diabetes by inhibition of inflammatory response and protection structure of pancreaticβcells.

Summary: To determine the biological effects of extracelluar signal regulated kinase (ERK) specific inhibitor PD98059 on pancreatic stellate cells (PSCs) activated by platelet-derived factor-BB (PDGF-BB), cultured rat PSCs were co-incubated at 37 ℃ for 24 h with 25 ng/ml PDGF-BB and different doses of PD98059 (ranging from 5 ng/ml to 40 ng/ml). Expression of pERK1 protein was detected by Western blot and collagen α1 (Ⅰ) mRNA was tested by reverse transcription-polymerase chain reaction (RT-PCR). Our results showed that there were statistical differences in the expression of pERK1 protein in all groups. Expression of pERK1 protein was up-regulated in the group treated by PDGF-BB, and gradually down-regulated in the other groups treated by PD98059 of different doses. An excellent positive correlation was revealed between the inhibitory effect and PD98059 concentrations. It was also observed that the expression of collagen α1 (Ⅰ) mRNA had similar response to pERK1. The level of collagen α1 (Ⅰ) mRNA was the highest in the PDGF-BB group, and gradually reduced in the other groups treated by PD98059 of different doses. It is concluded that expression of pERK1 protein and collagen α1 (Ⅰ) mRNA was up-regulated in rat PSCs activated by PDGF-BB. Meanwhile, PD98059 could inhibit PSCs activation mediated by PDGF. It is suggested that ERK1 protein plays an important role on PSCs activation mediated by PDGF signal pathway.

In handling crises in hospitals caused by natural disasters like earthquake, systemati cpractical measures of crisis management are needed, which include: early contact with top managements for support in counter disaster supplies, immediate organization of temporary first aid stations by hospital staff, logistic support by full time personnel to solve problems such as drugs and medical equipments as well as food and drinking water, and psychological consultation to patients and staff members.

ObjectiveTo systematically sort out the knowledge framework and conceptual logic relationship of "disease-syndrome-treatment-prescription-medicine" in the existing literature on traditional Chinese medicine（TCM） treatment of diabetic peripheral neuropathy（DPN）， to construct of the knowledge map of TCM treatment of DPN， and to promote the explicitation of the implicit knowledge in the literature on the treatment of DPN with TCM. MethodTaking the literature of China National Knowledge Infrastructure about TCM treatment of DPN as the main data source， TCM-related concepts and entities were constructed by manual citation， and the corresponding relationships between the entities were established. Structured data were formed by processing with Python 3.7， and the knowledge graph was constructed based on Neo4j 3.5.34 graph database. ResultThe resulting knowledge graph with TCM diagnosis and treatment logic， defined 12 node labels such as prescriptions， Chinese medicines and syndrome types at the schema layer， as well as 4 types of relationships， such as inclusion， correspondence， selection and composition. It could support the query and discovery of nodes（syndrome elements， syndrome types and treatment methods）， as well as the relationship between each node. ConclusionBased on the literature data， this study constructed a knowledge map for TCM treatment of DPN， which brought together various methods of TCM treatment of DPN， including internal and external treatment. The whole chain knowledge structure of syndrome differentiation and classification for DPN treatment is formed from syndrome element analysis， syndrome type composition to treatment method selection， which can provide new ideas and methods for literature data to serve clinical and scientific research work， as well as reference for visualization of TCM literature knowledge， intellectualization of TCM knowledge services and the standardization of TCM diagnosis and treatment.

Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.
