BACKGROUND: Intestinal and lymphoid tissues constitute an important part of intestinal immunity, which plays an important regulatory role in spleen deficiency and hydronephrosis. OBJECTIVE: To observe the effect of acupuncture on T lymphocyte subsets in lymph nodes of rats with spleen deficiency, and to investigate the correlation of spleen deficiency with intestinal immunity and the mechanism of acupuncture for spleen deficiency syndrome. METHODS: Thirty-six female Sprague-Dawley rats were randomly divided into three groups: model, acupuncture and blank control groups. The rat model of spleen deficiency was established by fatigue-induced spleen injury plus abnormal diet for 31 days. Afterwards, the rats in the acupuncture group received acupuncture at Zusanli(ST 36).Urine D-xylose excretion rate was detected during modeling and treatment.Then, the mesenteric lymph nodes were removed, and the changes in T lymphocyte subsets in the mesentericlymph nodes were observed by immunohistochemistry. RESULTS AND CONCLUSION: Urine D-xylose excretion rate under spleen deficiency in the modeling and acupuncture groups was significantly lower than that in the blank control group (P < 0.05 or P < 0.01); after acupuncture, the urine D-xylose excretion rate was significantly increased compared with the modeling group (P < 0.01), but still lower than that in the blank control group (P < 0.05). The count of CD4+T lymphocytes, count of CD8+T lymphocytes and ratio of CD4+/CD8+T lymphocytes were ranked as follows: blank control group >acupuncture group>modeling group(P<0.01 or P<0.05).These results suggest that acupuncture at Zusanli can improve the urine D-xylose excretion rate, regulate the balance of T lymphocyte subsets in mesenteric lymph node of rats with spleen deficiency, thus improving the intestinal immune function, spleen deficiency systems, disorder of intestinal digestive function, intestinal digestion and absorption, as well as anorexia, loose stool, diarrhea and other symptoms of the digestive system.

Alzheimer's disease （AD） is a neurodegenerative disease that leads to progressive memory and cognitive impairment and behavioral disorders， which has seriously threatened the health of the majority of middle-aged and elderly people. Traditional Chinese medicine （TCM） believes that the basic pathogenesis of AD is deficiency of kidney-essence， blood stasis and meridian stagnation. In recent years， many studies have shown that TCM has obvious value and advantages in the prevention and treatment of AD by multi-target mechanism. Therefore， it is of great significance to screen out effective anti-AD drugs from TCM compound prescriptions. Huangjingwan， also known as Jiuzhuan Huangjingwan， has the effects in tonifying kidney-essence， activating blood and removing stasis， with a potential effect in preventing AD. In this article， the feasibility of Huangjingwan in the prevention and treatment of AD was analyzed and discussed from the perspective of TCM theory， the study results of Huangjingwan in the prevention and treatment of AD were summarized， and the mechanism of its action was analyzed from the perspective of pharmacological mechanism. Based on TCM theory， Huangjingwan has the effect of anti-AD. According to relevant findings， Huangjingwan has many targets， such as anti-oxidation， anti-inflammatory， decrease of the level of oxidative stress in brain， activation of Wnt/β-catenin signal transduction in brain， regulation of glycogen synthase kinase-3β （GSK-3β）， protein phosphatase 2A （PP2A） activity balance， reduction of amyloid β （Aβ） content and tau protein hyperphosphorylation in brain， so as to exert effects in improving neurological symptoms and increasing learning and memory ability， with an anti-AD neuroprotective function. This will provide new ideas for in-depth studies and clinical applications of Huangjingwan against AD.

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.
