OBJECTIVE To explore the antidepressant effect and potential mechanism of icariside Ⅱ （ICSⅡ） based on the GABAergic nervous system. METHODS The male Kunming mice were randomly divided into a control group （group C， 10 mice） and a modeling group （50 mice）. The depression model was induced by chronic unpredictable mild stress （CUMS） method in the modeling group. After 21 days of stimulation， the rats of modeling group were randomly divided into depression model group （NS group）， positive control group [ECS group， oxalate escitalopram 15 mg/（kg·d）] and ICSⅡ low-dose， medium-dose and high-dose groups [ICSⅡ-L group， ICSⅡ-M group， ICSⅡ-H group； ICSⅡ 10， 20， 30 mg/（kg·d）]， with 10 mice in each group. Administration groups were given relevant medicine intragastrically， once a day， for 14 consecutive days. The sugar water preference rate， total exercise distance， immobility time in tail suspension and forced swimming experiments were detected in each group. The morphology of neurons and Nissl bodies in the hippocampal CA3 region were observed； the contents of γ-aminobutyric acid （GABA） and glutamic acid （Glu）， GABA/Glu ratio， and the expressions of GABAergic nervous system-related proteins （GABA A receptor α1， GABA B receptor 1， vesicular GABA transporter， glutamate decarboxylase 67， GABA membranal transporter 3） were detected in hippocampus. RESULTS Compared with group C， the sugar water preference rate and the total exercise distance significantly reduced in NS group， while the values of immobility time in the tail suspension test and forced swimming test were significantly prolonged （P＜0.05）. The morphology of neurons in the CA3 area of the hippocampus was irregular and the Nissl bodies were reduced， with a significant decrease in the number of structurally intact neurons （P＜0.05）； the content of Glu was significantly increased， while the content of GABA， GABA/Glu ratio， and the expressions of GABAergic nervous system-related proteins were significantly decreased （P＜0.05）. Compared with NS group， depression behavior in each administration group was improved， and the above indexes were mostly reversed （P＜0.05）. CONCLUSIONS ICSⅡ can improve depression behavior of depression model mice. The mechanisms may be associated with regulating the balance of GABA and Glu， increasing the synthesis， transport and release of GABA， and regulating the expressions of GABA-related receptors， so as to improve GABAergic nervous system.

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 discuss the effects of walking function-guided interactive Tuina(Chinese therapeutic massage)on spatiotemporal gait parameters in children with spastic cerebral palsy(CP). Methods:Fifty children with spastic diplegic CP were divided into an observation group and a control group following a paired design and random number principle,with 25 cases in each group.The observation group was treated with the walking function-guided interactive Tuina,and the control group was offered the"six methods of spine and back"Tuina,20 min for each session and 5 sessions weekly for 3 consecutive months.The children's changes were assessed using the percentage of dimension E(walking,running,and jumping)of the gross motor function measure-88(GMFM-88)and three-dimensional gait analysis. Results:After treatment,the percentage of GMFM-88 dimension of dimension E(walking,running,and jumping)changed significantly in both groups(P<0.05),and the between-group difference was also statistically significant(P<0.05).After treatment,the step length,walking speed,and step frequency changed markedly in the observation group(P<0.05)and were significantly different from those in the control group(P<0.05).After the intervention,the stance phase and double support extended,and the swing phase became shorter in the observation group(P<0.05);the between-group differences were statistically significant(P<0.05).The maximal knee flexion angle and maximal posterior pelvic tilt angle decreased After treatment in the observation group,and the maximal anterior pelvic tilt angle increased,all showing statistical significance(P<0.05);the between-group differences were statistically significant(P<0.05). Conclusion:Compared with the passive Tuina manipulations,the"six methods of the spine and back",walking function-guided interactive Tuina has its advantage in improving walking function in children with spastic CP,manifesting as better lower-limb force line and walking efficiency.

OBJECTIVES: To explore the effect mechanism of electroacupuncture (EA) on functional constipation (FC) at the combined lower he-sea and front-mu points of large intestine based on enteric neuronal autophagy. METHODS: A total of 40 SPF Kunming mice were randomly divided into 5 groups (n = 8), i.e. a control group, a model group, an acupuncture group, a 3-methyl adenine (3-MA) group, and a 3-MA + acupuncture group. Except the control group, the FC model was established by gavage with compound diphenoxylate suspension for 14 days in the other 4 groups. After successful modeling, the mice of the acupuncture group and the 3-MA + acupuncture group received EA at bilateral "Tianshu" (ST 25) and "Shangjuxu" (ST 37), stimulated for 30 min with disperse-dense wave, 2 Hz/15 Hz of frequency, 1 mA of intensity. EA was delivered once daily. One course of treatment was composed of 5 days and 2 courses were needed, with an interval of 2 days. An intraperitoneal injection of 3-MA (15 mg/kg) was administered 30 min before EA in the mice of the 3-MA group and the 3-MA + acupuncture group, once daily. Before and after intervention, the time of the first black stool defecation and defecation behaviors in 6 h were observed in each group. After intervention, in every group, the small intestine propulsion rate was calculated, the colon tissue morphology was observed using HE staining, the ultrastructure of enteric neuronal autophagy was observed under transmission electron microscope, and the expressions of microtubule-associated protein 1 light chain 3 (LC3), Beclin-1 and neuronal nuclear antigen protein (NeuN) in neurons of colonic muscularis were determined by immunohistochemistry. RESULTS: Before intervention, when compared with those in the control group, the time of the first black stool defecation was prolonged (P<0.01, P<0.05), and numbers (P<0.01), wet weight (P<0.01, P<0.05) and water content (P<0.05, P<0.01) of stool in 6 h were reduced in the model, acupuncture, 3-MA and 3-MA + acupuncture groups. After intervention, compared with those in the control group, the time of the first black stool defecation was longer (P<0.05), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were decreased in the model group. The time of the first black stool defecation was shortened (P<0.01), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were increased in the acupuncture group when compared with those in the model group. The time of the first black stool defecation was extended (P<0.01), and numbers (P<0.01), wet weight (P<0.01) and water content (P<0.01) of stool in 6 h were declined in the 3-MA + acupuncture group in comparison with those in the acupuncture group. All layers of colon tissue were normal and intact in each group. When compared with the control group, the small intestine propulsion rate and the average optical density (OD) values of LC3, Beclin-1 and NeuN in neurons of colonic muscularis were decreased (P<0.01), and autophagosomes were dropped in the model group. In the acupuncture group, the small intestine propulsion rate and the average OD values of NeuN, LC3 and Beclin-1 in neurons of colonic muscularis increased (P<0.01,P<0.05), and autophagosomes were elevated when compared with those in the model group. The small intestine propulsion rate and the average OD values of NeuN, LC3 and Beclin-1 in neurons of colonic muscularis were dropped (P<0.05,P<0.01) in the 3-MA + acupuncture group in comparison with those in the acupuncture group. CONCLUSIONS Electroacupuncture may promote enteric neuronal autophagy and increase the number of neurons so that the intestinal motility can be improved and constipation symptoms can be relieved in FC mice.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective:To observe the effect of Ba Duan Jin(Eight-brocade Exercise)plus Tuina(Chinese therapeutic massage)in treating primary dysmenorrhea due to cold-induced blood stasis in female college students and on the score of fatigue scale-14(FS-14). Methods:Seventy-two female college students with primary dysmenorrhea due to cold-induced blood stasis were randomized into a Tuina group and a joint group,with 36 cases in each group.The Tuina group only received Tuina manipulations.In the joint group,besides the same Tuina manipulations,patients practiced Ba Duan Jin.For both groups,the once-daily intervention was conducted from 6 d before the menstrual period until menstrual day 1 for 3 menstrual cycles.Changes in the scores of COX menstrual symptom scale(CMSS),visual analog scale(VAS),and FS-14 after the intervention were observed.Clinical efficacy was also estimated. Results:During the process,1 case dropped out in the Tuina group,and 35 cases completed the intervention;2 cases dropped out in the joint group,and 34 cases completed the intervention.The total effective rate was 94.1%in the joint group,higher than 88.6%in the Tuina group(P<0.05).After treatment,the symptom duration and intensity scores in the scores of CMSS,VAS,and FS-14 declined in both groups(P<0.05 or P<0.01);the CMSS symptom duration score and FS-14 score were lower in the joint group than in the Tuina group(P<0.05). Conclusion:Tuina manipulations alone or combined with Ba Duan Jin practice can effectively treat primary dysmenorrhea due to cold-induced blood stasis in female college students;when combined with Ba Duan Jin practice,Tuina manipulations can more significantly improve pain duration and fatigue,suggesting the advantages of combining Tuina Gongfa and manipulations.

OBJECTIVE: To analyze the literature knowledge structure and acupoint matching rules of acupuncture for depression. METHODS: The articles regarding acupuncture for depression published from January 1 of 1984 to October 19 of 2020 were searched in CNKI database. CiteSpace5.7.R2 software was used to import the literature data, and the keyword cluster analysis, emergence analysis and time-zone analysis of articles and acupoints were conducted, and the map of scientific knowledge was draw. RESULTS: A total of 3524 articles were included to the knowledge structure analysis, while 601 articles into the acupoint matching rules analysis. There were 13 keyword clusters of acupuncture for depression, with "post-stroke depression" and "electroacupuncture treatment" as high-frequency keywords, and "electroacupuncture treatment" and "Hamilton depression scale" had high centrality, and "electroacupuncture treatment" had the highest emergence intensity. The keywords such as "electroacupuncture treatment" and "Hamilton depression scale", etc. appeared the earliest, followed by "post-stroke depression", "fluoxetine" and "auricular point therapy", etc. According to traditional Chinese medicine theory, acupoint keywords were divided into four clusters: ①core acupoint, ②replenishing-spleen and dispelling phlegm, dispersing-liver and relieving depression, reinforcing CONCLUSION The main knowledge structure of acupuncture for depression includes five parts: treatment method, depression type, TCM-related diseases, literature type and curative effect index. Clinical acupoint matching should adhere to the principle of "focusing the disease before syndrome" and "combination of disease and syndrome", and treatment should be modified for the syndromes of phlegm stagnation blocking, liver-stagnation and

Colchicine plays an important role in the treatment of gout and some other diseases. Besides gastrointestinal symptoms, myopathy has been reported as a rare side effect of colchicine in some patients. We report a case of myopathy in a patient with chronic kidney disease caused by high-dose colchicine, and then review literature on colchicine-induced myopathy, so as to provide some experience for the clinical diagnosis, treatment and medication safety. A 51-year-old male patient with 10 years of gout and 5 years of chronic kidney disease history and irregular treatment was admitted to the hospital with complaint of recurrent left wrist arthralgia and emerging lower extremities myalgia after intake of 40-50 mg colchicine in total within 20 days. Laboratory examinations showed significantly increased creatine kinase (CK) and then colchicine-induced myopathy was diagnosed preliminarily. After withdrawl of colchicine and implementation of hydration, alkalization and intramuscular injection of compound betamethasone, the symptoms of arthralgia and myalgia were relieved within 3 days and CK decreased to normal range gradually. According to literature reports, colchicine related myopathy was mostly characterized by proximal myasthenia and myalgia, accompanied by elevated CK level, which usually occurred days to weeks after initial administration of colchicine at the usual dosage in patients with renal impairment or a change in the underlying disease state in those receiving long-term therapy, and the features might remit within three to four weeks after the drug was discontinued. Electromyography of proximal muscles showed myopathy marked by abnormal spontaneous activity and muscle pathology waa marked by accumulation of lysosomes and autophagic vacuoles. Chronic kidney disease, liver cirrhosis, higher colchicine dose and concomitant cytochrome P450 3A4 (CYP3A4) inhibitors were associated with increased risk of myo-pathy. Based on the similar efficacy and lower adverse reaction rate compared with larger dosage, small dose of colchicine was recommended by many important current guidelines and recommendations in the treatment of gout. In consideration of potential risks, colchicine should be used with caution in patients with kidney or liver impairment, and in those taking CYP3A4 or P-glycoprotein inhibitors. For those patients, the drug dose should be adjusted and the latent adverse reactions should be monitored carefully.
