ObjectiveTo investigate the mechanisms of Runmu Dihuang decoction （RMDHD） in treating perimenopausal dry eye with liver-kidney Yin deficiency syndrome based on the silent information regulator 3 （SIRT3）/hypoxia-inducible factor-1α （HIF-1α）/nuclear factor-κB （NF-κB） signaling pathway. MethodsSixty female Sprague-Dawley rats were randomly divided into six groups （n=10 per group）： Sham operation group， model group， sodium hyaluronate eye drop group， and low-， medium-， and high-dose RMDHD groups （5.625， 11.25， 22.50 g·kg^-1）. Except for the sham operation group， all rats underwent bilateral ovariectomy and were administered 0.1% benzalkonium chloride eye drops combined with long-term chronic irritation to establish a perimenopausal dry eye model with liver-kidney Yin deficiency syndrome. Drug administration began in the 11th week after modeling and continued for 21 days. General conditions， screen-grip test scores， tear secretion volume， tear film breakup time （TFBUT）， and corneal fluorescein staining were recorded. Serum levels of reactive oxygen species （ROS）， follicle-stimulating hormone （FSH）， estradiol （E₂）， and progesterone （PROG） were measured by enzyme-linked immunosorbent assay （ELISA）. Pathological changes in the lacrimal glands， corneas， and uteri were observed using hematoxylin-eosin （HE） staining. Protein expression levels of SIRT3， HIF-1α， phosphorylated NF-κB p65 （p-NF-κB p65）， and total NF-κB p65 in the lacrimal glands were detected by Western blot. The expression of inflammatory cytokines interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in the lacrimal glands was assessed by immunohistochemistry （IHC）. ResultsAfter model establishment， no significant differences were observed among the groups except the sham operation group. Compared with the sham operation group， the other groups exhibited slowed movement， dull responses， increased irritability， reduced body weight， elevated rectal temperature， decreased screen-grip test scores， reduced tear secretion， and significantly shortened TFBUT （P<0.05）. After treatment， compared with the model group， the sodium hyaluronate eye drop group and all RMDHD groups showed improved general conditions， significantly increased tear secretion （P<0.05）， prolonged TFBUT （P<0.05）， and elevated screen-grip test scores （P<0.05）. Serum ROS and FSH levels were significantly decreased， while E₂ and PROG levels were significantly increased （P<0.05）. Pathological damage to the cornea， lacrimal glands， and uterus was ameliorated. In addition， protein expression levels of SIRT3 and HIF-1α in the lacrimal glands were significantly upregulated （P<0.05）， whereas the expression of p-NF-κB p65， IL-1β， and TNF-α was significantly downregulated （P<0.05）. ConclusionRMDHD increases tear secretion and TFBUT， improves lacrimal gland and corneal injury， and alleviates dry eye symptoms in a perimenopausal dry eye rat model with liver-kidney Yin deficiency syndrome. The underlying mechanism may be related to regulation of the SIRT3/HIF-1α/NF-κB signaling pathway， inhibition of oxidative stress and inflammatory responses， and reduction of ocular surface tissue damage.

The importance of consensus research in medical decision-making has become increasinglyprominent. However, this field has long lacked unified terminology definitions and reporting standards, leading to significant heterogeneity in study design, implementation, and result presentation that affects the credibility and reproducibility of outcomes. The ACCurate COnsensus Reporting Document (ACCORD) in the field of biomedical research provides a structured writing framework for various consensus methods such as the Delphi method and nominal group technique, aiming to enhance the completeness and transparency of study reports. Combined with specific cases, this article interprets the core items of ACCORD, offering references for the design, implementation, and reporting of high-quality consensus research in China.

Objective To investigate the protective effects and possible mechanisms of sofalcone on small intestinal mucosal damage induced by nonsteroidal anti-inflammatory drugs(NSAIDs)in rats.Methods In the first group of animal experiments,rats were randomly divided into five groups:normal control group,diclofenac group(diclofenac 7.5 mg·kg-1),and sofalcone high-doses groups(sofalcone 10 mg·kg-1+diclofenac 7.5 mg·kg-1),sofalcone medium-doses groups(sofalcone 5 mg·kg-1+diclofenac 7.5 mg·kg-1),and sofalcone low-doses groups(sofalcone 2 mg·kg-1+diclofenac 7.5 mg·kg-1).Each group received daily gavage for seven days.Serum D-lactate levels were measured,and histological damage to the small intestine was assessed through HE staining and pathological scoring.In the second group,rats were separated into three groups:normal control group,diclofenac group(diclofenac 7.5 mg·kg-1),and sofalcone group(sofalcone 2 mg·kg-1+diclofenac 7.5 mg·kg-1).Concurrently,the rats'body mass,24-hour diet,and water intake were monitored.Additionally,serum levels of pro-inflammatory cytokines such as IL-6,IFN-γ,TNF-α,inflammatory markers CRP and D-lactate,as well as measurements of tissue reactive oxygen species(ROS),lactate dehydrogenase(LDH),and mitochondrial membrane potential were conducted using appropriate kits.Western blotting was applied to assess the expression levels of intercellular junction proteins(Occludin,Claudin-1,α-Catenin),programmed necrosis pathway-associated proteins including receptor-interacting protein kinase 1(RIPK1),RIPK3,and mixed lineage kinase domain-like pseudokinase(MLKL)along with p-MLKL.Results In the first experiment,the diclofenac group exhibited significant histological damage to the small intestine,with elevated levels of D-lactic acid and pathological scores compared to the normal control group(P<0.01).Following intervention with sofalcone,both the histological damage and the levels of D-lactic acid and pathological scores in the small intestine were notably reduced(P<0.05 or P<0.01).However,there was no substantial difference in pathological scores among different doses of sofaclone groups(P>0.05).In the second experiment,compared with normal control group,rats in the diclofenac group showed decreased body mass,24-hour average diet and water intake,along with elevated levels of IL-6,IFN-γ,TNF-α,CRP,D-lactic acid,tissue ROS,LDH activity,RIPK1,RIPK3,and p-MLKL/MLKL protein expression levels,as well as mitochondrial membrane potential(P<0.05 or P<0.01).Moreover,Occludin,Claudin-1,and α-Catenin protein expression levels were reduced(P<0.05 or P<0.01).Following sofalcone intervention,the previously mentioned parameters were reversed(P<0.05 or P<0.01).Notably,there was no statistically significant difference observed in the reduction of RIPK1 protein expression(P>0.05).Conclusions Sofalcone reduces NSAID-induced small intestinal mucosal injury in rats by inhibiting the RIPK1/RIPK3/MLKL-dependent programmed necrosis pathway.

Objective:To summarize and analyze the clinical characteristics and treatment outcomes of patients with recurrent pericarditis.Methods:This observational study consecutively recruited patients with recurrent pericarditis who were hospitalized at Peking University People′s Hospital between January 2017 and February 2024. Clinical characteristics and treatment outcomes were collected and summarized during follow-up.Results:A total of 8 recurrent pericarditis patients including 3 males were included, with an age of 34.0 (22.0, 39.5) years. In terms of clinical features, all patients presented with acute-onset severe chest pain, accompanied by fever in 7 and an audible pericardial friction rub in 2 patients. Electrocardiogram showed no diffuse ST-segment elevation or PR-segment depression in any patient. Echocardiography revealed pericardial effusion in all cases, with extensive fibrinous exudate and transient pericardial thickening observed in 6 patients. CT identified concurrent pleural and/or peritoneal effusions in 6 patients. All patients exhibited marked elevations in C-reactive protein, erythrocyte sedimentation rate and D-dimer levels. Whole-exome sequencing identified MEFV gene mutations associated with familial Mediterranean fever in 3 cases. Two patients developed cardiac tamponade requiring pericardiocentesis, which revealed hemorrhagic effusion. In the aspect of treatment outcomes, the time from recurrence to first confirmed diagnosis of recurrent pericarditis of this cohort was 14.5 (13.3, 19.5) d. Upon diagnosis, all patients promptly received standard anti-inflammatory therapy with ibuprofen and colchicine, achieving rapid relief. However, during a follow-up of 12.0 (6.0, 25.3) months, 3 patients experienced recurrence, and 2 developed transient constrictive pericarditis.Conclusion:Patients with recurrent pericarditis typically exhibit characteristic clinical presentations, laboratory abnormalities, imaging findings and potential genetic associations. Although standard anti-inflammatory therapy demonstrates favorable short-term efficacy, long-term management remains challenging due to the risks of recurrence and progression to constrictive pericarditis.

Objective:To determine the clinical issues in the Clinical practice guidelines for postoperative pain management in adults (2024 edition). Methods:A preliminary list of clinical issues for the guidelines was developed through literature review, clinical surveys, and expert interviews.
