Sepsis remains a significant challenge for healthcare systems worldwide,despite advancements in diagnostic and therapeutic approaches that have mitigated its impact.The underlying pathophysiological mechanisms of sepsis are not yet fully understood.Autophagy,a cellular stress response,has been shown to play a critical role in the de-velopment of sepsis.Golgiphagy,a specific autophagic process targeting the Golgi apparatus,has been identified as a key factor influencing sepsis pathophysiology.This process operates through autophagy-related receptors and contributes to or-gan damage during sepsis.This review will explore the receptors associated with Golgiphagy,its role in sepsis progres-sion,and its effects on various organs,with the goal of informing treatment strategies for sepsis.

Objective To investigate the inhibitory effect of bromfenac sodium hydrate ophthalmic solution on corneal neovascularization (CNV) induced by alkali burn.Methods A total of 192 specific pathogen free (SPF) degree adult male Sprague-Dawley (SD) rats were used in this study.One hundred and seventy-two rats were chosen to establish CNV model with alkali burn in the right eyes.Following alkali burn,rats were randomly divided into CNV group,model control group,bromfenac sodium group and fluorometholone group,with 43 rats (43 eyes) in each group.Another 20 rats (40 eyes) served as normal control group.One day after modeling,the model control group,bromfenac sodium group and fluorometholone group received phosphate buffer saline (PBS),bromfenac sodium hydrate ophthalmic solution and 0.1％ fluorometholone eye drops,respectively.The state of cornea and anterior chamber and the growth of CNV of rats in each group were observed by slit-lamp microscope every day after modeling.At 1,3,7,14,21 and 28 days after modeling,the anterior segment photos of the experimental eyes were captured,and the percent of cornea areas covered by CNV was calculated.At 7,14 and 28 days after modeling,the eye tissue sections were stained with hematoxylin and eosin staining and immunohistochemistry staining to evaluate the expressions of CD45 and VEGF-A.Real-time quantitative PCR and enzyme-linked immunosorbent assay (ELISA)were used to detect the expression of COX-2 and VEGF mRNA and protein level.The use and care of the animals complied with the Statement of the Association for Research in Vision and Ophthalmology(ARVO).Results Each model group showed corneal edema and opacification 1 day after modeling.The corneal edema was aggravated 7 days after modeling.On the 14th day after modeling,the degree of corneal opacity and edema decreased gradually.On the 28th day after modeling,leucoma was observed in CNV group and model control group,and nebula was observed in bromfenac sodium group and fluorometholone group.At 7,14,21 and 28 days after modeling,the percentages of CNV areas in bromfenac sodium group and fluorometholone group were significantly lower than those in CNV group and model control group (all at P＜0.05).No significant difference was found in the percentage of CNV areas between bromfenac sodium group and fluorometholone group at various time points (all at P＞0.05).On the 7th day after modeling,the thinning of corneal epithelial layer,edema and arrangement disorder of stroma layer were observed,and the expression of VEGF-A was positive in all model groups;a small amount of CD45 positive inflammatory cell infiltrations were observed in CNV group and model control group.On the 14th and 28th day after modeling,CNV was seen in the center of cornea in CNV group and model control group;the epithelial keratosis and reduction of corneal edema were seen in each group,and no inflammatory cell infiltration was observed in each group.On the 7th day after modeling,the expressions of COX-2 and VEGF mRNA in CNV group and model control group were significantly higher than those in normal control group,bromfenac sodium group and fluorometholone group (all at P ＜ 0.05),the expressions of COX-2 and VEGF protein in bromfenac sodium group were significantly lower than those in CNV group (all at P＜0.05).The corneal peroration rate in model control group and bromfenac sodium group was 10％ (1 case in 10 rats).The corneal perforation rate in fluorometholone group was 30％ (3 cases in 10 rats).In each model group,10％ to 30％ rats had hyphema.Conclusions Bromfenac sodium hydrate ophthalmic solution can inhibit the formation and growth of CNV after alkali burn in rats.This effect may be mediated by regulating COX-2 expression,reducing inflammation and inhibiting VEGF production.

Objective To study the rat pulmonary irritant of aerosol inhaled Tanreqing and Reduning injection .Methods Rats were devided into two groups for each medicine (low concentration group and high concentration group ) ,nebulized drug administration for seven days ,with the control group irrigated with saline ,and were sacrificed .Through bronchoalveolar lav-age ,excurrent bronchoalveolar lavage fluid (BALF) was used for total protein determination and LDH vitality test to evaluate pulmonary toxicity of two medicines .Results The protein concentrations of two groups in low and high concentrations of Tan-reqing and Reduning respectively are (193 .78 ± 27 .74) ,(235.33 ± 50.41)μg/ml;(174 .02 ± 17 .82) ,(227 .27 ± 66 .03)μg/ml;LDH vitalities respectively are 1065 .21 ± 181 .76 ,1467 .33 ± 101 .87;307 .97 ± 47 .56 ,1377 .29 ± 566 .48 .By t-test ,compared with normal saline ,there was no significant effect among these five groups on protein concentration ,but these two medicine were able to improve LDH activity (P<0 .05) which was more obvious in high concentration group .When two medicines were in low concentration ,LDH activity was higher in Tanreqing group with statistical significance (P<0 .05) .Conclusion Aero-sol inhaled Tanreqing and Reduning injection in rats have some pulmonary irritation and potential safety hazard in this delivery w ay .

OBJECTIVETo study pharmacokinetic of puerarin in rats following different methods of administration of Tongqiao Sanyu prescription.

METHODTongqiao Sanyu prescription was administered to rats by caudal vein injection, nasal administration and oral administration. Plasma samples were extracted with methanol and the plasma concentration of puerarin was analyzed by RP-HPLC. The pharmacokinetic parameters and bioavailability were calculated with Kinetica software.

RESULTThe main pharmacokinetic parameters were as follows: AUC(0-infinity) of caudal vein injection was (787.99 +/- 70.44) mg x min x L(-1); AUC(0-infinity) of nasal administration was (376.56 +/- 93.93) mg x min x L(-1); AUC(0-infinity) and oral administration (The dose was decuple higher than that of caudal vein injection and nasal administration) was (491.18 +/- 110.64) mg x min x L(-1). The absolute bioavailability of puerarin was 47.78% by nasal administration and 6.23% by oral administration.

CONCLUSIONThe bioavailability of nasal administration is higher than oral administration significantly, this result can provide some scientific foundantion for the method of administration and the reform of dosage form of Tongqiao Sanyu prescription.
