This paper summarizes professor LI Guolie's clinical experience in treating orthostatic hypotension （OH） based on the theory of "raising the clear and directing the turbid downward". It is considered that the core pathogenesis of OH lies in the body's transition from a supine to an upright position， during which dysfunction of the middle jiao （焦） transformation and transportation， along with impaired pivot function， hinders the ascending of clear yang and the descending of turbid yin. Treatment should follow the general principle of "ascending the clear and directing the turbid downward"， placing emphasis on distinguishing the primary and secondary aspects. For cases where the clear yang fails to ascend， the self-formulated Li's Shengqing Jiangzhuo Decoction （李氏升清降浊汤）is used to supplement qi， raise the clear， and strengthen the middle jiao. For cases where the turbid yin fails to descend， the self-formulated Wuxiang Qingzhuo Beverage（五香清浊饮）with modifications is applied to resolve phlegm， eliminate stasis， harmonize the middle， and descend the turbid.

This paper expounds Professor Li Guolie's academic thought and clinical experience in treating the halitosis of spleen and stomach damp-heat type based on the theory of"lightness removing excess".It is proposed that"lightness"has five meanings:light and clear medicinal properties,light dosage,concise compatibility,light decoction method and light treatment method;"excess"covers the syndromes of external and internal injuries,obstruction of qi mechanism and mixed deficiency and excess.The location of the halitosis of spleen and stomach damp-heat type is centered on the spleen and stomach in the middle energizer,involving the lungs,liver,and kidneys,with syndromes of mixed deficiency and excess;the core pathogenesis is the stagnation of qi mechanism in the mid-dle energizer and the diffusion of damp-heat turbid evil in the triple energizers.The theory of"lightness removing excess"is used to guide the treatment of spleen and stomach diseases of damp-heat type,and the treatment principle of"triple energizers being divided and eliminated,and lightness being able to penetrate and reach the evil"is proposed.The upper energizer is promoted to activate the pivot of qi transformation,the middle energizer is adjusted to restore the mechanism of ascending and descending,and the lower energi-zer is penetrated to guide the turbid evil out.The self-made"Wuxiang Qingzhuo Yin"is used to gargle to quickly remove the turbid e-vil and symptoms,forming an internal and external coordinated diagnosis and treatment method of"light dosage to regulate the pivot,ingenious method to clear the obstruction",which provides new ideas and theoretical basis for the clinical diagnosis and treatment of spleen and stomach diseases of damp-heat type.

Idiopathic pulmonary fibrosis (IPF), a chronic interstitial lung disease, is characterized by aberrant wound healing, excessive scarring and the formation of myofibroblastic foci. Although the role of alternative splicing (AS) in the pathogenesis of organ fibrosis has garnered increasing attention, its specific contribution to pulmonary fibrosis remains incompletely understood. In this study, we identified an up-regulation of serine/arginine-rich splicing factor 7 (SRSF7) in lung fibroblasts derived from IPF patients and a bleomycin (BLM)-induced mouse model, and further characterized its functional role in both human fetal lung fibroblasts and mice. We demonstrated that enhanced expression of Srsf7 in mice spontaneously induced alveolar collagen accumulation. Mechanistically, we investigated alternative splicing events and revealed that SRSF7 modulates the alternative splicing of pyruvate kinase (PKM), leading to metabolic dysregulation and fibroblast activation. In vivo studies showed that fibroblast-specific knockout of Srsf7 in conditional knockout mice conferred resistance to bleomycin-induced pulmonary fibrosis. Importantly, through drug screening, we identified lomitapide as a novel modulator of SRSF7, which effectively mitigated experimental pulmonary fibrosis. Collectively, our findings elucidate a molecular pathway by which SRSF7 drives fibroblast metabolic dysregulation and propose a potential therapeutic strategy for pulmonary fibrosis.

Under the background of breaking the " five only" evaluation criteria, continuously optimizing the scientific research performance evaluation system of hospitals to mobilize the enthusiasm and creativity of scientific researchers and guide the direction of scientific research development plays an important role in enhancing the overall scientific research capability of hospitals. Through literature analysis and expert consultation, a certain hospital has constructed a personal scientific research performance evaluation index system for medical staff in tertiary public hospitals, oriented towards innovation quality and member contributions, and began to implement it throughout the hospital in 2021. This index system included four categories of scientific research performance: vertical scientific research projects, academic influence, science and technology awards, and transformation of achievements, with a total of 20 indicators. The annual scientific research performance score of an individual would serve as the basis for the distribution of year-end scientific research performance and an important reference for applying for key and major projects within the hospital. After the application of this evaluation index system, the enthusiasm of medical staff for scientific research has been effectively stimulated. The average individual scientific research performance score increased from 0.974 in 2020 to 1.220 in 2023. All scientific research indicators involved in the evaluation system have shown growth, with a significant increase in high-quality results. This evaluation system can provide a reference for the scientific research performance evaluation of public hospitals under the background of breaking the " five only" evaluation criteria.

Spinocerebellar ataxia 17 (SCA17) is an autosomal dominant cerebellar ataxia caused by an abnormal expansion of the CAG/CAA sequence in the TATA-box binding protein ( TBP) gene. According to CAG size range, there are 2 clusters: reduced-penetrance in low-range expansions and full-penetrance in larger expansions. Here, a patient genetically diagnosed with SCA17 and with 43 CAG repeats in the TBP gene, presenting symptoms resembling multiple system atrophy (MSA), is reported. Further review of previously reported cases of SCA17 with a small range of expansions shows the clinical manifestations of SCA17 are highly heterogeneous, of which clinicians need to have sufficient awareness. For patients clinically suspected of having MSA, even if their clinical features and imaging manifestations more strongly support the sporadic neurodegenerative disease, SCA17 should still be considered as one of the differential diagnoses.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.
