OBJECTIVE To explore the improvement effect and mechanism of salidroside on radiation-induced parotid gland injury in rats. METHODS Rats were randomly assigned into normal group， radiation group， salidroside low-dose （salidroside-L， 50 mg/kg） group， salidroside high-dose （salidroside-H， 100 mg/kg） group， and salidroside-H+inhibitor （100 mg/kg salidroside+0.1 µmol/kg H-89） group， with 10 rats in each group. Except for the normal group， rats in the other groups were subjected to radiation exposure to establish a model of radiation-induced parotid gland injury. Rats in each group were intraperitoneally injected with the corresponding drug or normal saline， once a day， for 40 consecutive days. After the last administration， the levels of reactive oxygen species （ROS）， cyclic adenosine monophosphate （cAMP）， superoxide dismutase （SOD）， and amylase in serum were detected； the pathological changes of parotid gland tissue were observed； the apoptosis rate of parotid gland tissue cells， the expression levels of B-cell lymphoma-2 （Bcl-2） and its associated X protein （Bax）， mRNA expression levels of interleukin-6 （IL- 6） and tumor necrosis factor-α （TNF-α）， the protein expression levels of type Ⅲ collagen （Col Ⅲ）， vasoactive intestinal peptide （VIP）， and the phosphorylation level of protein kinase A （PKA） in parotid gland tissue were determined. RESULTS Compared with normal group， the levels of ROS， amylase， apoptosis rate， Bax expression level， mRNA expression levels of IL-6 and TNF- α， and protein expression level of Col Ⅲ in the radiation group were significantly increased， while the levels of cAMP， SOD， Bcl-2 expression level， VIP protein expression level and PKA phosphorylation level were significantly decreased （P＜0.05）. Compared with radiation group， the above indicators in the salidroside-L group and salidroside-H group were significantly improved （P＜0.05）， and the improvement in the salidroside-H group was more significant （P＜0.05）； inhibitor H-89 significantly reversed the changes in the above indicators of the salidroside-H group （P＜0.05）. CONCLUSIONS Salidroside can effectively alleviate radiation-induced parotid gland injury in rats， and its mechanism may be related to the activation of the VIP-cAMP pathway.

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 evaluate the efficacy and safety of albumin bound paclitaxel(nab-PTX)and solvent based paclitaxel(sb-PTX)in neoadjuvant chemotherapy(NACT)for advanced epithelial ovarian cancer(EOC).Methods:A retrospective analysis was conducted on the clinical data of 107 patients with advanced EOC who un-derwent preoperative NACT in the First Affiliated Hospital of Xi'an Jiaotong University from June 11,2018 to Sep-tember 19,2023.Among them,52 patients were treated with nab-PTX combined with carboplatin intravenous chemotherapy(nab-PTX group),and 55 with sb-PTX combined with carboplatin intravenous chemotherapy(sb-PTX group).The clinical indicators after NACT,intraoperative conditions of cytoreductive surgery and ad-verse events during the NACT were compared in two groups.Results:The maximum tumor diameter(3.7 cm vs.3.8 cm),CA125(28.9 U/ml vs.31.6 U/ml)and HE4(102.5 U/ml vs.119.0 U/ml)levels in the nab PTX group after NACT were significantly lower than those in the sb-PTX group,and the differences were statistically significant(P＜0.001).After NACT,the total input(2580 ml vs.2100 ml),the proportion of surgical complexity score(36.54％vs.18.18％),and lymph node resection rate(57.69％vs.29.09％)in the nab-PTX group were significantly higher than those in the sb-PTX group(P＜0.05).There was no statistically significant difference(P＞0.05)in the amount of ascites,clinical efficacy evaluation,ORR,DCR,surgical time,intraoperative bleeding,total output,postoperative hospital stays,surgical satisfaction,pathological complete response rate(pCR),transfu-sion of blood products,lymph node metastasis and adverse effects during NACT between the two groups.Con-clusions:Nab-PTX has a better clinical disease control effect than sb-PTX in NACT,in order to achieve better cy-toreductive surgery,but it has no significant effect on pathological remission.The safety of the two drugs is similar.
