By consulting the ancient and moderm literature， this paper makes a textual research on the name， origin， quality evaluation， harvesting and processing of Olibanum， so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research， the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu（《名医别录》）， until Ruxiang had been used as the correct name since Bencao Shiyi（《本草拾遗》） in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia， while the modern producing areas are Somalia， Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark， which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow， granular， translucent， no impurities such as sand and bark， sticky powder and aromatic smell. There were many processing methods in ancient times， including cleansing（water flying， removing impurities）， grinding（wine grinding， rush grinding）， frying（stir-frying， rush frying， wine frying）， degreasing， vinegar processing， decoction. In modern times， the main processing methods are simplified to cleansing， stir-frying and vinegar processing. Nowadays， the commonly used specifications include raw， fried and vinegar-processed products. Among the three specifications， raw products is the Olibanum after cleansing， fried products is a kind of Olibanum processed by frying method， vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results， it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum， processing method should be carried out in accordance with the processing requirements of the formulas， otherwise used the raw products if the formulas without clear processing requirements.

Objective To investigate the effects of cynomorium songaricum extract on cognitive dysfunction of Alzheimer disease (AD) model mice based on network pharmacology and animal experiments.Methods Network pharmacology was used to predict the related targets and signal pathways of the extract of cynomorium songaricum to improve AD.Senescence accelerated mice P8 (SAMP8) were selected as the model of AD.Based on the results of the preliminary experiment, 0.17 g/(kg·d) was selected as the optimal dosage for the extract of cynomorium son-garicum.The extract of cynomorium songaricum [0.17 g/(kg·d) , Donepezil hydrochloride [2.0 mg/(kg·d) ] and normal saline were given orally for 28 days according to the groups.Morris water maze evaluated the learning and cognitive function of animals.The number of neurons in cornu ammonis 1 (CA1) of hippocampus was observed by Nissl staining.The expression of recombinant Beclin 1(Beclin-1), Sequestosome 1 (p62), light chain 3 (LC-3) protein was detected by immunohistochemical method.The protein expression levels of phosphoinositide 3-ki-nase (PI3K), protein kinase B (AKT) and glycogen synthase kinase3β(GSK-3β) in the hippocampus of mice in each group were detected by Western blot.Results Based on the network pharmacology study, it was predicted that the biological mechanism of cynomorium songaricum to improve AD might be the regulation of autophagy, and the possible signaling pathway was PI3 K/AKT/GSK-3β.The results of animal experiments showed that the extract of cynomorium songaricum could improve the spatial memory learning ability of AD model mice, improve the dam-age of hippocampal neurons, significantly increase the number of neurons, and increase the expression levels of PI3K, p-AKT/AKT, p-GSK-3β/GSK-3β, Beclin-1 and LC3 in the hippocampus of mice.The expression level of p62 decreased.There was no significant difference between male and female mice during the experiment.Conclu-sion The extract may improve the cognitive dysfunction of male and female AD models by activating autophagy mediated by PI3K-AKT-GSK-3β signaling pathway, and there is no significant gender difference in the effect.

Cerebral ischemia-reperfusion injury(CIRI)is a serious complication caused by the recovery of blood flow in the affected brain tissue of patients with ischemic stroke.CIRI patients are often accompanied by neurological dysfunction,cognitive impairment,emotional disorders and other symptoms,which have a serious impact on daily life.At present,CIRI is easy to be diagnosed early,but there are relatively few related specific treatments.In this paper,the correlation between cyclic adenylate-activated exchange protein 1/RAS-related protein 1(Epac1/Rap1)signaling pathway and CIRI is reviewed,in order to provide new ideas for clinical treatment of CIRI patients.

Objective To investigate the effects of acute sleep deprivation on the behavior and synaptic protein expression of rats.Methods Seventy healthy male Wistar rats were randomly divided into seven groups,a Control group and sleep deprivation groups(24,48,72,96,120 and 144 hours).The sleep deprivation rat model was established by the modified multiplatform water environment sleep deprivation method.Spatial learning and memory were assessed by the Morris water maze.Anxiety was assessed by the open field test.The morphology and quantity of hippocampal neurons were observed by Nissl staining.Western blot and Real-time PCR were used to determine the expression of synaptophysin(SYN),post-synaptic density protein-95(PSD-95),and brain-derived neurotrophic factor(BDNF)in rats.Results Compared with the Control group,the numbers of standing and modification were significantly increased by prolongation of the sleep deprivation time(P＜0.05).The escape latency and path length were significantly increased in 120 and 144 h groups(P＜0.05),whereas the number of platform crossings and the percentage of the target quadrant time were significantly decreased(P＜0.01)and negatively correlated to the sleep deprivation time.The expression levels of BDNF,SYN,and PSD-95 were significantly decreased with the prolongation of sleep deprivation time(P＜0.01).Conclusions With the increase in sleep deprivation time,cognitive dysfunction and anxiety gradually deteriorated,which may be related to decreases in the expression of synaptic biomarkers.

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.

In order to provide the basis for the development of famous classical formulas， the name， origin， quality evaluation， harvesting and processing of Eucommiae Cortex were systematically researched by consulting the ancient herbal and medical books， combining with the modern literature. According to the textual research， materia medica in the past dynasties used Eucommiae Cortex as the correct name. Combined with characteristics， origin and efficacy， Eucommiae Cortex in ancient times to the present is the dry bark of Eucommia ulmoides from family Eucommiaceae. The earliest producing areas of Eucommiae Cortex are Henan， Shanxi， Shaanxi and Sichuan. Since the Ming dynasty， the producing areas have expanded to most of the regions in the country， and Sichuan， Shaanxi， Chongqing， Guizhou and Hubei are regarded as the authentic producing areas. It has been concluded that the quality of Eucommiae Cortex is best if the bark has thick body， large block， scraped rough skin， multi silk section and dark purple internal surface. In ancient times， the processing methods of Eucommiae Cortex were mainly included removing rough bark and cutting for raw use， processing with auxiliary materials such as honey， ginger juice， salt water， wine， and so on. While in modern times， the processing methods have become increasingly simplified which are mainly cutting raw materials after cleansing and salt processing. It is need to excavate the connotation of different processed products and restore the traditional main processing methods through standards. Based on the requirement of Eucommiae Cortex in Sanbitang， it is suggested to use ginger-processed products according to the research results， which is used ginger juice as auxiliary material and processed with stir frying method according to the 2020 edition of Chinese Pharmacopoeia.

【Objective】 To evaluate the effect of one-beat acquisition with wide detector CT on the image quality and diagnostic efficiency of coronary CT angiography (CCTA) in patients with atrial fibrillation. 【Methods】 A total of 52 consecutive patients with atrial fibrillation, including 31 males, (67.32±11.45) years old, who underwent CCTA from July 2022 to February 2023, were analyzed retrospectively. All patients underwent one-beat acquisition CCTA. The subjective and objective image quality of the coronary arteries was evaluated, and using invasive coronary catheter angiography as the gold standard, the diagnostic efficacy of stenosis degrees above moderate and severe degrees was calculated, respectively. 【Results】 Subjective evaluation results: 92.31% (384/416) of the vascular segments were rated as excellent or good, and the diagnosable rate reached 98.08% (408/416, subjective score ≥3 points). Objective evaluation results: The CT value of the right coronary artery, anterior descending branch, and circumflex branch was (433.41±95.17)HU, (422.69±92.81)HU and (420.27±95.43)HU, respectively; the contrast-to-noise ratio was 38.46±7.54, 32.46±13.78 and 37.74±8.89, respectively. The total diagnostic accuracy, sensitivity, and specificity was 94.71%, 87.9% and 96.62%, respectively, for moderate stenosis and 96.15%, 83.64% and 98.06% for severe stenosis. 【Conclusion】 One-beat acquisition with wide detector CT can obtain high-quality coronary artery images and high diagnostic accuracy for patients with atrial fibrillation without radiation dose increase to patients. It has good clinical application value for patients with atrial fibrillation.

【Objective】 To compare the enhancement effects of lean body weight （LBW） and total body weight （TBW） as indexes to calculate the contrast agent dosage under the condition of energy spectrum CT scanning. 【Methods】 A total of 218 patients who received liver enhancement CT from November 2018 to January 2019 were enrolled in this study. There were 101 patients in LBW group and 117 patients in TBW group. Both groups were scanned by energy spectrum CT， and the parameters of scanning and reconstruction were identical. The contrast agent dose was 500 mgI/kg （LBW） in LBW group and 450 mgI/kg （TBW） in TBW group， and the injection rate was 2.8 mL/s. Images were transferred to a GE AW4.7 workstation and the 50 keV monochromatic images were analyzed. We compared the dosage of contrast medium， CT value of aorta in arterial phase （HU-aorta）， hepatic enhancement CT value in venous phase （-liver）， the rate of reaching the enhancement standard and variability in the two groups. 【Results】 Compared with TBW group， LBW group had lower contrast agent dosage， HU-aorta and ∆-liver （P<0.05）， LBW and TBW group had no statistically different enhanced rate of HU-aorta as （91.09% vs. 90.60%） or ∆-liver （92.08% vs. 88.89%） （P>0.05）. The variation rate of HU-aorta and ∆-liver in LBW group was lower than that in TBW group. Using LBW as an index to calculate the dosage of liver enhanced CT also made the enhancement of liver parenchyma more consistent in different patients. 【Conclusion】 Even on the premise of energy spectrum CT scanning， using LBW-based contrast injection in liver enhanced CT can not only reduce contrast dose， but also make the enhancement in liver parenchyma more consistent among different patients.

【Objective】 To investigate the effects of 80 kVp combined with multi-model adaptive statistical iterative reconstruction algorithm （ASiR-V） on the image quality of CT angiography （CTA） of iliac artery in kidney transplantation candidates before operation. 【Methods】 Totally 50 kidney transplantation candidates underwent “one-stop” scanning combined CTA for coronary and iliac arteries were recruited consecutively. After the scanning， images were reconstructed with different ASiR-V levels on the iliac artery from 50% to 100% at a 10% interval， and 6 groups of images were obtained. We evaluated and compared all image qualities， DLP and CTDI in the patients’ examination were recorded， and the effective dose （ED） was calculated. 【Results】 All of the image quality objective scores of different ASiR-V levels on the iliac artery were above 3 points （3.32±0.24）， and the average CT value was （344.30±74.53）HU. The ED received by the patient throughout the examination was （2.71±0.42)mSv. The image noise decreased while SNR and CNR increased monotonically as the ASiR-V levels increased， among which 80% ASiR-V image quality score was the highest with 3.41±0.26. 【Conclusion】 For patients who need to have both coronary and iliac arteries evaluated before kidney transplantation operation， low tube voltage （80 kVp） combined with 80% ASiR-V can obtain high-quality iliac artery images under the premise of reducing the ED dose， which can provide practical basis for further reducing the dose in personalized scanning scheme for such patients. It has good feasibility and clinical application value.

Objective: To observe the anesthesia and hemodynamic effect of etomidate compound remifentanyl in laparoscopic surgery. Methods: From January 2016 to May 2016, 160 patients with gynecologic laparoscopic surgery in the Second Hospital of Shanxi Medical University were selected and randomly divided into observation group and control group according to the digital table, with 80 cases in each group.The observation group received the etomidate compound remifentanyl anesthesia, while the control group received the propofol compound remifentanyl anesthesia.the The anesthesia effect, awakening time, extubation time, pain relief time and systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) before and after extubation of the two groups were observed and recorded. Results: The excellent and good rate in the observation group was 98.0%, which was significantly higher than 86.0% in the control group (χ²=4.444, P<0.05). The waking time, extubation time, analgesic time in the observation group were shorter than those in the control group, the differences were no statistically significant(t=1.875, 1.631, 1.761, all P>0.05). At tracheal intubation, the SBP, DBP, HR and other indicators between the two groups had no statistically significant differences(t=1.301, 1.093, 1.097, all P>0.05). After induction of anesthesia, the SBP, DBP in the observation group were higher than those in the control group, the differences were statistically significant(t=6.182, 7.388, all P<0.05), but HR between the two groups had no statistically significant difference(t=1.428, P>0.05). After laparoscopic placement and tracheal extubation, the SBP and DBP in the observation group were significantly higher than those in the control group, the differences were statistically significant (t=5.781, 5.028, all P<0.05), and the SBP in the observation group was higher than that in the control group after tracheal extubation(t=1.203, 1.039, all P<0.05). Conclusion The anesthesia effect of etomidate compound remifentanyl is superior to propofol compound remifentanyl, the hemodynamic parameters of SBP, DBP, HR are more stable during the period of anesthesia, the curative effect is clear.
