Objective To analyze the factors influencing the early recovery of renal function in patients with sepsis-associated acute kidney injury(SA-AKI).Methods A retrospective analysis was conducted on 86 SA-AKI patients treated in the Intensive Care Unit at Zhongshan Hospital,Fudan University from January 2021 to December 2022,who met both the Sepsis 3.0 diagnostic criteria and the AKI diagnostic standards.Patients were divided into a recovery group and a non-recovery group based on whether their renal function recovered within 7 days after AKI onset.Clinical data and laboratory tests of patients were compared between the two groups.Univariate and multivariate logistic analyses were used to identify risk factors affecting renal function recovery in SA-AKI patients,and ROC curve was utilized to evaluate the predictive value of these factors for early renal function recovery in SA-AKI patients.Results The renal function of 37(43.02％)patients recoveried.Compared with the recovery group,the renal replacement therapy rate,in-hospital mortality and 28-day mortality of patients in the non-recovery group were higher(P＜0.001).The multivariate logistic analysis showed that age,APACHE Ⅱ score,urine output,urine neutrophil gelatinase-associated lipocalin(NGAL),and norepinephrine dose were independent related factors affecting renal function recovery in SA-AKI patients(P＜0.05).The final model logit(P)=-4.091+0.001×urine NGAL-0.001 Xurine volume+0.040 ×age+0.073 × APACHE Ⅱ score+1.906 × norepinephrine dose.The AUC of model predicting early SA-AKI recovery was 0.823,with 73.5％of sensitivity,and 81.1％of specificity.Conclusions In SA-AKI patients,age,APACHE Ⅱ score,urine output,urine NGAL,and the dose of norepinephrine independently affect early renal function recovery,and the combined assessment of these indicators has predictive value for the early renal recovery in these patients.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.

Objective To retrospectively analyze the ultra-fast track anesthesia(UFTA)methods and perioperative anesthesia management experiences of transcatheter mitral valve edge-to-edge repair(TEER)in the treatment of functional mitral regurgitant.Methods In this retrospective study,patients underwent the TEER procedure and received UFTA in Fuwai Yunnan Hospital,from May 2022 to September 2022 for heart failure combined with moderate to severe or severe functional mitral regurgitant were included.Baseline,preoperative complications,cardial function and anesthesia classification,amino-terminal probrain natriuretic peptide(NT-proBNP),ultrasound examination results,surgery time,extubation time,intraoperative anesthetic and vasoactive drug,complications related to TEER and UFTA,perioperative,and postoperative 30-day and one-year follow-up data were collected.All perioperative clinical data were recorded and analyzed.Results A total of 30 patients were enrolled,11 patients(36.7％)were female,mean age was(63.6±6.1)years,NYHA classification IV 14 patients(46.7％),left ventricular ejection fraction(LVEF)(36.0±8.1)％,the end-diastolic volume of the left ventricle(66.0±8.2)mm,mitral regurgitation 4+14 patients(56.7％),3+17 patients(43.3％),NT-proBNP(1 934.1±1 973.5)pg/ml,1 patient(3.3％)used high-dose vasoactive drugs during surgery.All patients did not experience nausea,vomiting,delirium,respiratory depression,perioperative transesophageal echocardiography-related gastrointestinal bleeding,pericardial effusion,cerebrovascular accidents,emergency surgery or secondary intervention,or other serious adverse events within 24 hours after surgery.No 30-day all-cause death occurred;the mean postoperative hospital stay was(7.4±2.8)days.All patients completed one-year follow-up,LVEF(37.6±11.1)％,the end-diastolic volume of the left ventricle(63.2±8.6)mm,mitral regurgitation 2+7 patients(23.3％),1+23 patients(76.7％),NT-proBNP(1 949.2±2 576.6)pg/ml.Conclusions Ultra-fast track anesthesia can be safely applied to TEER in treating functional mitral regurgitant patients.

Aim To investigate the regulatory mecha-nism of butin on the proliferation,migration,cycle blockage and pyroptosis related inflammatory factors in human fibroblast-like synoviocytes of rheumatoid arthri-tis(HFLS-RA).Methods Cell proliferation,migra-tion and invasion were studied using cell migration and invasion assays.Cell cycle was detected by flow cytom-etry,and the expression of the pyroptosis-associated in-flammatory factors IL-1β,IL-18,caspase-1 and caspase-3 was detected by ELISA,RT-qPCR and West-ern blot.Results Migration and invasion experiments showed that the cell proliferation rate of the butin group was lower than that of the blank control group(P＜0.05).Cell cycle analysis demonstrated that in the G0/G1 phase,the DNA expression was elevated in the medium and high-dose groups of butin(P＜0.05),while in the G2 and S phases,the DNA expression was reduced in the medium and high-dose groups of butin(P＜0.05).The results of ELISA,RT-qPCR and Western blot assay revealed that the expression of IL-1β,IL-1 8,caspase-1,and caspase-3 decreased in the butin group compared with the IL-1β+caspase-3 in-hibitor group(P＜0.05).Conclusions Butin inhib-its HFLS-RA proliferation by inhibiting the synthesis of inflammatory vesicles by caspase-1 in the pyroptosis pathway,thereby reducing the production and release of inflammatory factors such as IL-1β and IL-18 down-stream of the pathway,and also inhibits HFLS-RA pro-liferation by exerting a significant blocking effect in the G1 phase,which may be one of the potential mecha-nisms of butin in the treatment of RA.

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.

The global COVID-19 coronavirus pandemic has infected over 109 million people, leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment. Here, we screened about 1.8 million small molecules against the main protease (M^pro) and papain like protease (PL^pro), two major proteases in severe acute respiratory syndrome-coronavirus 2 genome, and identified 1851M^pro inhibitors and 205 PL^pro inhibitors with low nmol/l activity of the best hits. Among these inhibitors, eight small molecules showed dual inhibition effects on both M^pro and PL^pro, exhibiting potential as better candidates for COVID-19 treatment. The best inhibitors of each protease were tested in antiviral assay, with over 40% of M^pro inhibitors and over 20% of PL^pro inhibitors showing high potency in viral inhibition with low cytotoxicity. The X-ray crystal structure of SARS-CoV-2 M^pro in complex with its potent inhibitor 4a was determined at 1.8 Å resolution. Together with docking assays, our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development.

The differences in dryness between raw Aurantii Fructus Immaturus(AFI) and bran-fried products were investigated based on a slow-transit constipation(STC) model. Seventy healthy SPF-grade rats were randomly divided into a blank group(K), a positive drug group(Y), a model group(M), low-and high-dose raw AFI groups(SD and SG), and low-and high-dose bran-fried AFI groups(FD and FG). During the experiment, it was found that compared with the K group, the groups with drug treatment had little effect on the daily body weight of the STC rats. The first defecation time of black stool in the M group was significantly higher than that in the K group, and the 24-hour fecal output significantly decreased starting from the 13th day, indicating successful modeling. The SG group showed a significant increase in the first defecation time, fecal water content, urine output, and water intake than other groups with drug treatment. The FG group had the highest fecal output than other groups with drug treatment. The FD group had the highest salivary secretion than other groups with drug treatment. The levels of cAMP/cGMP, VIP, 5-HT, AQP1, and AQP5 were measured in each group with drug treatment, and the expression of c-Kit and SCF mRNA in gastric antrum tissue and AQP3 mRNA in the kidney and colon were detected by RT-PCR. The results showed that the SD and SG groups had a more significant impact on AQP1, AQP5, and other water channel indexes in STC rats than the FD and FG groups. The FD and FG groups had a more significant impact on c-Kit, SCF, VIP, 5-HT, and other gastrointestinal motility indicators than the SD and SG groups. This study, through in vitro biological observations, immunological detection, and gene expression analysis, found that raw AFI had strong dryness property, while bran-fried AFI could alleviate its dryness property.

The lung is one of the most common sites for cancer metastasis. Collagens in the lung provide a permissive microenvironment that supports the colonization and outgrowth of disseminated tumor cells. Therefore, down-regulating the production of collagens may contribute to the inhibition of lung metastasis. It has been suggested that miR-29 exhibits effective anti-fibrotic activity by negatively regulating the expression of collagens. Indeed, our clinical lung tumor data shows that miR-29a-3p expression negatively correlates with collagen I expression in lung tumors and positively correlates with patients' outcomes. However, suitable carriers need to be selected to deliver this therapeutic miRNA to the lungs. In this study, we found that the chemotherapy drug cisplatin facilitated miR-29a-3p accumulation in the exosomes of lung tumor cells, and this type of exosomes exhibited a specific lung-targeting effect and promising collagen down-regulation. To scale up the preparation and simplify the delivery system, we designed a lung-targeting liposomal nanovesicle (by adjusting the molar ratio of DOTAP/cholesterol-miRNAs to 4:1) to carry miR-29a-3p and mimic the exosomes. This liposomal nanovesicle delivery system significantly down-regulated collagen I secretion by lung fibroblasts in vivo, thus alleviating the establishment of a pro-metastatic environment for circulating lung tumor cells.

This study was designed to assess the clinical efficacy of oral blood-activating and stasis-removing Chinese patent medicines in treating hypertensive left ventricular hypertrophy(LVH) based on network Meta-analysis. The clinical randomized controlled trials(RCTs) concerning the treatment of hypertensive LVH with oral blood-activating and stasis-removing Chinese patent medicines were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, and Cochrane Library from their inception to September 2021. Two researchers independently completed the literature screening, data extraction, and quality evaluation. The data were then analyzed by RevMan 5.3, Stata 15.1, and ADDIS 1.16.8. Finally, a total of 31 RCTs were included, involving 3 001 patients and four oral blood-activating and stasis-removing Chinese patent medicines. In terms of the alleviation of heart damage, the Chinese patent medicines combined with conventional western medicine groups were superior to the conventional western medicine groups in lo-wering the left ventricular mass index(LVMI). There was no significant difference in LVMI, left ventricular ejection fraction(LVEF), or the ratio of early diastolic peak flow velocity to late diastolic peak flow velocity(E/A) between different Chinese patent medicines combined with conventional western medicine groups. Xinnao Shutong Capsules/Tablets combined with conventional western medicine had the best efficacy in reducing LVMI and elevating LVEF, while Xinkeshu Capsules/Tablets combined with conventional western medicine had the best effect in improving E/A. In the control of blood pressure, when all Chinese patent medicines except for Xinnao Shutong Capsules/Tablets were combined with conventional western medicine, the resulting systolic blood pressure(SBP) and diastolic blood pressure(DBP) were significantly lower than those in the conventional western medicine group. Xinkeshu Capsules/Tablets combined with conventional western medicine produced the best effect in reducing SBP and DBP, followed by Xinnao Shutong Capsules/Tablets. In terms of safety, no serious adverse reactions occurred in all trials. The four oral blood-activating and stasis-removing Chinese patent medicines included in this study exhibited obvious advantages in the treatment of hypertensive LVH when they were combined with conventional western medicine, with the best effects observed in the Xinnao Shutong Capsules/Tablets combined with conventional western medicine group. However, due to the limitation of the quantity and quality of the included articles, the conclusion of this study still needs to be verified by more high-quality, multi-center, and large-sample RCTs.
