Objective To explore the effects of different sevoflurane elution methods on awakening quality and cognitive function of elderly obese patients undergoing hip joint replacement.Methods A total of 90 elderly obese patients underwent hip joint replacement under intravenous inhalation combined with general anesthesia and maintained anesthesia with sevoflurane during surgery were selected as the research subjects,and randomly divided into group A and group B,and sevoflurane was eluted by closed elution method and decreasing concentration elution method,respectively.The concentration of sevoflurane exhaled and cognitive function scores at different time points of patients between the two groups were compared,and the awakening quality and the occurrence of adverse reactions during the awakening period of patients between the two groups were compared.Results At the end of the surgery,the concentration of sevoflurane exhaled by patients in group B was significantly lower than that in group A(P<0.05),and the recovery time,awakening time,tracheal extubation time,and anesthesia recovery room stay time of patients in group B were significantly shorter than those in group A(P<0.05).The incidence of agitation during the awakening period of patients in group B was significantly lower than that in group A(P<0.05),and the cognitive function score at the time of 2 hours after awakening of patients in group A was significantly lower than that in group B(P<0.05).Conclusion For elderly obese patients undergoing hip joint replacement with intravenous inhalation combined with general anesthesia,sevoflurane can be eluted by decreasing concentration elution method before the end of surgery,and the patient wakes up smoothly and in a shorter time,with fewer adverse reactions and less impact on postoperative cognitive function.

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 explore the efficacy of Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction on adult chronic insomnia and its effect on hypnotic withdrawal.METHODS 187 patients with chronic insomnia were included for anal-ysis,including 102 in the traditional Chinese medicine(TCM)group and 85 in the western medicine group.The TCM group was trea-ted with Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction,while the western medicine group was treated with benzodiazepine under the consideration of doctor.The intervention period was 1 month,with assessments using the Pittsburgh Sleep Quality Index(PSQI)conducted before and after the intervention.Follow-up evaluations were performed at 3 months and 6 months re-spectively after the intervention.RESULTS There was no significant difference between the two groups at baseline.After the inter-vention,the PSQI scores of patients in both groups were significantly improved(P<0.01).Among them,the TCM group was better than the western medicine group in the improvement of sleep quality and sleeping pills,total PSQI score reduction(P<0.01).The re-sults of linear regression analysis showed that after controlling for confounding factors,the regression coefficients of the TCM group in two different models were1.821 and 1.922 respectively,and the former was statistically significant(P<0.05).By screening patients who took hypnotics at baseline in the TCM group and comparing them with those in the western medicine group,the influencing factors of hypnotic withdrawal were analyzed.During the 3-month follow-up,25 out of 39 patients in the TCM group and 17 out of 80 patients in the western medicine group had hypnotic withdrawal(χ2= 19.25,P<0.001);during the 6-month follow-up,23 of the 39 patients in the TCM group and 18 of the 79 patients in the western medicine group had hypnotic withdrawal(χ2= 13.53,P<0.001),the with-drawal rate of patients in the TCM group was significantly higher than that in the western medicine group.Further regression analysis showed that after adjusting for confounding factors,the results showed that the western medicine group had a significantly higher rate of not withdrawal than the TCM group at 3 months(OR=5.50,95%CI:2.30～13.72)and 6 months(OR=6.43,95%CI:2.54～17.77),and the results were statistically different(P<0.05).CONCLUSION Sour Jujube Seed Decoction combined with Huangli-an Wendan Decoction is effective in treating adult chronic insomnia and assisting in hypnotic withdrawal.

ObjectiveTo investigate the possible mechanism of Bushen Zhuyun prescription （BSZYP） to reduce the level of ovarian apoptosis in Brown Norway （BN） rats with luteal phase deficiency （LPD）. MethodFifty SPF female BN rats were randomly divided into a model group， a dydrogesterone group （0.002 g·kg^-1）， and a low （4.5 g·kg^-1）， a medium （9 g·kg^-1）， and a high-dose （18 g·kg^-1） BSZYP groups， with ten rats in each group. The rats were administrated with corresponding drugs by gavage， once a day for three estrus cycle. Western blot was used to detected the protein expression levels of c-Jun NH2 terminal kinase （JNK）， extracellular signal-regulated kinase （ERK）， phosphorylated-ERK （p-ERK）， phosphorylated-JNK （p-JNK）， p38 mitogen-activated protein kinase （p38 MAPK）， phosphorylated-p38 MAPK （p-p38 MAPK ）， B-cell lymphoma （Bcl-2）， and Bcl-2 associated X protein （Bax） in ovary. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression levels of ERK， JNK， p38 MAPK， Bax， and Bcl-2 in ovary. Enzyme-linked immunosorbent assay （ELISA） was used to detect the serum progesterone （P） and estradiol （E₂） levels. Hematoxylin-eosin （HE） staining was used to observe the ovarian tissue morphology. ResultCompared with the model group， the recovery of estrus cycle of rats in all BSZYP groups had statistical significance after 1-circle administration （P<0.05）. The ovarian tissue morphology in the low-dose BSZYP group was improved， and that in the medium and high-dose BSZYP groups was significantly improved with clear follicle， less vesicular follicle and atretic follicle， and more granular layers. The number of luteum， especially the fresh luteum， in the medium and high-dose groups was increased with smooth edge and large volume. The mRNA expression level of Bcl-2 was increased in all-dose BSZYP groups， while the mRNA expression level of Bax was significantly decreased in all-dose BSZYP group （P<0.05， P<0.01）. The mRNA expression levels of JNK and p38 MAPK were significantly decreased in the high-dose BSZYP group （P<0.01）， and the mRNA expression levels of ERK were increased in the low and medium-dose BSZYP groups （P<0.05）. The protein expression level of Bcl-2 was significantly increased in the medium and high-dose BSZYP groups （P<0.01）， and the protein expression level of Bax was significantly decreased in the all-dose BSZYP groups （P<0.01）. No significant difference was observed in the protein expressions of JNK， ERK， and p38 MAPK in the BSZYP groups. The protein expression levels of p-ERK in the ovarian tissues of rats were significantly inoreased in the medium and high-dose BSZYP group （P<0.01）， p-JNK， and p-p38 MAPK in the ovarian tissues of rats were significantly decreased in the medium and high-dose BSZYP group （P<0.01）. The level of E₂ was increased in all-dose BSZYP groups （P<0.05， P<0.01）， and the level of P in the medium-dose BSZYP group was increased （P<0.05）. ConclusionBSZYP improved the serum sex hormones， restored the estrous cycle， reduced atretic follicle and vesiculation， and maintained luteal morphology and function of BN rats， so as to improve luteal function and treat luteal phase deficiency. The mechanism of BSZYP may be related to reduce the level of ovarian tissue apoptosis in BN rats by regulating MAPKs signaling pathway.

Clinical staging, Gleason score, and prostate-specific antigen (PSA) have been accepted as factors for evaluating the prognosis of prostate cancer (PCa). With the in-depth study of iron metabolism and the development of multiparametric magnetic resonance imaging technology, we used q-Dixon magnetic resonance imaging (MRI) to measure the iron content of the PCa patients' lesions, and used enzyme-linked immunosorbent assay (ELISA) to measure the iron metabolism indicators in the patients' serum samples, combined with the patients' postoperative clinical data for analysis. We found that the serum indexes were correlated with the T2 star values, International Society of Urological Pathology (ISUP) grade, and pathological classification in PCa patients (all P < 0.001) but not in benign prostatic hyperplasia (BPH) patients (all P > 0.05). The utilization of q-Dixon-based MRI and serum indexes allows the noninvasive measurement of iron content in prostate lesions and the assessment of differential iron metabolism between PCa and BPH, which may be helpful for evaluating the prognosis of PCa.

To overview the systematic reviews of Panax notoginseng saponins in the treatment of acute cerebral infarction. CNKI, CBM, Wanfang, VIP, PubMed, Cochrane Library and EMbase databases were retrieved to collect the systematic reviews of the efficacy of P. notoginseng saponins in the treatment of acute cerebral infarction. The retrieval time was from the time of database establishment to January 2021. After two researchers independently screened out the literature and extracted the data, AMSTAR-2 scale was used to evaluate the methodological quality of the included systematic reviews, GRADE system was used to grade the quality of evidences of the outcome indicators, and the efficacy evaluation was summarized. A total of 5 systematic reviews were included. AMSTAR-2 evaluation results showed that 3 items were relatively complete, while 4 items had a poor overall quality. P. notoginseng saponins combined with conventional Western medicine therapy was superior to single conventional therapy in the recovery of neurological function, enhancement of the total effective rate in clinic, and improvement of activities of daily living. GRADE evaluation results showed that the quality of evidence was from low quality to very low quality. In conclusion, in the treatment of acute cerebral infarction, P. notoginseng saponins can improve the clinical efficacy, with a good safety but a not high methodological quality and a low evidence quality. It is suggested that high-quality clinical studies shall be further carried out to provide evidence-based basis for the application of P. notoginseng saponins in the treatment of acute cerebral infarction.
