Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.

Objective:To compare the efficacy and safety differences between direct mechanical thrombectomy (abbreviated as direct thrombectomy) and bridging therapy in patients with acute anterior circulation large vessel occlusion and atrial fibrillation.Methods:A retrospective collection of data was conducted for hospitalized patients who underwent mechanical thrombectomy due to acute anterior circulation large vessel occlusion with atrial fibrillation at the First Affiliated Hospital of Soochow University and Suzhou Kowloon Hospital, Shanghai Jiao Tong University School of Medicine from January 1, 2018 to December 31, 2022. Patients were divided into direct thrombectomy and bridging therapy groups based on whether intravenous thrombolysis was used, and the clinical outcomes and safety indicators of the two groups were compared. The primary clinical outcomes included the modified Rankin Scale (mRS) score at 90 days and the proportion of patients with neurological independence at 90 days (the proportion of patients with mRS scores of 0-2). Safety indicators included 90-day mortality rate, intracranial hemorrhage rate, symptomatic intracranial hemorrhage [deterioration of neurological function and an increase of ≥4 points in the National Institutes of Health Stroke Scale (NIHSS) score] rate, and pneumonia incidence. Using the 90-day prognosis as a dependent variable, a binary Logistic regression analysis was conducted to investigate the factors influencing poor prognosis in patients at 90 days.Results:Among the 534 screened patients, 125 were included in the study, with 74 in the direct thrombectomy group and 51 in the bridging therapy group. The difference in the mRS scores at 90 days between the direct thrombectomy group and the bridging therapy group was not statistically significant [2 (0, 3) vs 3 (1, 3), Z=-1.444, P=0.149]. The difference in the proportion of patients with independent neurological function at 90 days [66.2% (49/74) vs 47.1% (24/51), χ2=4.561, P=0.033] was statistically significant between the 2 groups. The 90-day mortality rate [5.4% (4/74) vs 9.8% (5/51), χ 2=0.936, P=0.483], the intracranial hemorrhage rate [17.6% (13/74) vs 29.4% (15/51), χ 2=2.437, P=0.119], the symptomatic intracranial hemorrhage rate [12.2% (9/74) vs 23.5% (12/51), χ 2=2.791, P=0.095], and the pneumonia incidence [59.5% (44/74) vs 56.9% (29/51), χ 2=0.084, P=0.772] between the 2 groups showed no statistically significant differences (all P>0.05). The time from admission to puncture was 97 (74, 122) min and 150 (127, 168) min for the direct thrombectomy and bridging therapy groups, respectively, with a statistically significant difference ( Z=-5.846, P<0.001). Binary Logistic regression analysis showed that venous thrombolysis (adjusted OR=3.004, 95% CI 1.057-8.539, P=0.039), NIHSS score at onset (adjusted OR=1.096, 95% CI 1.009-1.191, P=0.030), and pneumonia (adjusted OR=12.814, 95% CI 3.775-43.499, P<0.001) were associated with poor prognosis at 90 days. Conclusion:For patients with acute anterior circulation large vessel occlusion and atrial fibrillation, direct thrombectomy can increase the proportion of neurological independence at 90 days compared to bridging therapy, with no statistically significant differences in safety indicators, which may be related to the shorter time from admission to puncture in the direct thrombectomy group.

AIM To investigate the therapeutic mechanism of tanshinone ⅡA in a mouse model of chronic colitis induced by trinitrobenzene sulfonic acid(TNBS).METHODS The BALB/c mice were randomly divided into the control group,the model group,and the low-dose and high-dose tanshinone ⅡA groups(10,20 mg/kg).Chronic inflammatory bowel disease(IBD)was induced in the model and tanshinone ⅡA groups by epicutaneous application of 3.75 mg TNBS(dissolved in 48％ethanol),followed by intrarectal administration of TNBS(0.75,1.5 and 2.25 mg in 40％ethanol)on days 7,14 and 21.Starting on day 7 post-modeling,the mice underwent their 14-day consecutive dosing of corresponding drugs by gavage.The mice had their disease activity index(DAI)assessed;their colon length and weight measured;and their levels of inflammatory factors IFN-γ and TNF-α in the colon mucosa detected by ELISA.The wild-type and PXR-/-mice were randomly divided into the control group,the model group,and the tanshinone ⅡA group(20 mg/kg).After modeling and drug administration using the aforementioned method,Masson staining was used to assess the intestinal fibrosis;immunohistochemistry was employed to detect the colon expression of ZO-1 and Occludin proteins;and immunofluorescence was used to detect the colon expression of NF-κB p65.RESULTS Tanshinone ⅡA(20 mg/kg)reduced DAI scores,colon weight/length ratio,and the colon levels of IFN-γ and TNF-α of the mouse models(P＜0.05,P＜0.01).Compared with the WT control group,the WT model group and PXR-/-control group exhibited increased colon histopathological scores and fibrosis areas(P＜0.01),decreased protein expressions of ZO-1 and Occludin(P＜0.01),and increased expression of p-NF-κB p65(P＜0.01).Compared with the WT model group,the WT tanshinone ⅡA group showed reduced colon weight/length ratio,histopathological scores,and fibrosis areas(P＜0.01);increased protein expressions of ZO-1 and Occludin(P＜0.05,P＜0.01);and decreased expression of p-NF-κB p65(P＜0.01).However,tanshinone ⅡA showed no significant therapeutic effect upon PXR-/-model mice(P＞0.05).CONCLUSION Tanshinone ⅡA(20 mg/kg)can effectively alleviate TNBS-induced chronic colitis in mice,and this protective effect may be exerted by the modulation of PXR/NF-κB signaling pathway.

Suppressor of cytokine signaling 3(SOCS3),a member of SOCS family,plays a major role in cell signaling trans-duction.SOCS3 is important in regulation of immune homeostasis and also involved in the control of energy metabolism,mainly through regulating JAK/STAT pathway.Recent studies have shown that SOCS3 was closely associated with glycolipid metabolic diseases like diabetes and obesity,and can be used as a new target for treatment of these glycolipid metabolic diseases.This review focuses on the latest research progress of the role and mechanism of SOCS3 in glycolipid metabolic diseases,and discusses the possibility of SOCS3 as a therapeutic target for glycolipid metabolic diseases.

Aim To explore the effects of sirolimus on the growth and development of motor,vascular,nerv-ous,and immune systems through zebrafish models.Methods After 3 hours of fertilization of zebrafish embryos,different concentrations of sirolimus were add-ed to the growth environment,and the growth and de-velopment of the embryos was recorded.Transgenic ze-brafish models labeled with blood vessels,nerves or im-mune cells were used to compare the drug effects on the growth and development of those systems.Results At the concentration of 0.5 μmol·L-1,the hatching rate and the body length(P＜0.01)were significantly smaller than those of the control group,and movement was also significantly slowed down.Meanwhile,the length of axons of the nervous system,the development of intersegmental vessels,and the growth of immune cells were significantly delayed by drug treatment.But when the concentration was below 0.1 μmol·L-1,there was no statistically difference between the control group and the sirolimus group.Conclusions When the concentration of sirolimus exceeds a certain level,it can significantly slow down the growth and development of movement,blood vessels,nervous system and im-mune system of zebrafish.Therefore,in clinical prac-tice,it is important to monitor the blood concentration of sirolimus in children on time.

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.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.
