This paper systematically reviews the core concepts and lines of theoretical inheritance of major spleen-stomach theories in traditional Chinese medicine （TCM）， including spleen deficiency theory， spleen-stomach damp-heat theory， and liver-spleen disharmony theory. It is found that these theories have all undergone a developmental trajectory characterized by classical foundation， refinement of therapeutic methods， systematization of pathogenesis， and modern innovation. The evolution of spleen-stomach theory has achieved a shift from a singular focus on tonifying the spleen to regulating dynamic middle-jiao （焦） balance， and from localized spleen-stomach regulation to the circular movement of qi involving all five zang organs. In terms of modern disease-syndrome integrative research， spleen deficiency syndrome is shown to be closely associated with impairment of the gastrointestinal mucosal barrier， metabolic disorders， and gene polymorphisms related to Helicobacter pylori-associated gastric diseases. Spleen-stomach damp-heat syndrome is closely linked to hyperactive energy metabolism， inflammatory cytokines， and abnormal expression of aquaporins. Liver-spleen disharmony syndrome is mainly associated with dysregulation of the brain-gut axis and microbiota-related metabolic disorders. It is proposed that future research on spleen-stomach diseases and syndromes should further elucidate their potential multidimensional differential biological characteristics， thereby promoting the modernization of the TCM discipline of spleen-stomach studies.

OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland （HMG）. METHODS Female SD rats were divided into control group and HMG group according to body weight， with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling， two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid （calculated by crude drug） intragastrically， once a day， for 7 consecutive days. Blood samples were collected before the first administration （0 h）， and at 5， 15， 30 minutes and 1， 2， 4， 8， 12， 24 hours after the last administration， respectively. Using chlorzoxazone as the internal standard， the plasma concentrations of ferulic acid， paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve （AUC0－24 h， AUC0－∞）， mean residence time （MRT0－∞）， half-life （t1/2）， peak time （tmax）， peak concentration （cmax）] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group， the AUC0－24 h， AUC0－∞ and cmax of ferulic acid in the HMG group were significantly increased （P＜0.05）； the AUC0－24 h， AUC0－∞ ， MRT0－∞ ， t1/2 and cmax of paeoniflorin increased， but there was no significant difference between 2 groups （P＞0.05）； the AUC0－24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged （P＜0.05）. C ONCLUSIONS In HMG model rats， the exposure of ferulic acid， paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase， and the retention time of rosmarinic acid is significantly prolonged.

Objective: To analyze the factors associated with high level fear of negative evaluation (FNE) among junior high school students and to construct a nomogram risk prediction model, so as to provide scientific tools for psychological health intervention for junior high school students. Methods: A convenience sampling combined with cluster random sampling method was used to select 5 485 junior high school students from 4 cities (Wuhan, Huanggang, Xianning and Xiaogan) for an online questionnaire survey in March 2025. The total sample was randomly split into a training set ( n =3 839) and a validation set ( n =1 646). Univariate analysis was performed in the training set using Chi-square test and t-test. Variables with statistical significance were subsequently included in multivariate Logistic regression to identify independent predictors and to construct a nomogram based risk prediction model. The discriminative ability and clinical utility of the model were evaluated in the validation set using the area under the receiver operating characteristic curve (AUC), calibration curve, and decision curve analysis (DCA). Results: There were 1 649 junior high school students with low level FNE and 2 190 with high level FNE in the training set. The self control ability of junior high school students with lowlevel and high level FNE showed a statistically significant difference (23.96±3.96, 21.48±3.37, t=25.15, P < 0.01 ). Statistically significant differences in the detection rate of high level FNE were observed among junior high school students with different genders, family types, parenting styles, academic rankings, psychological flexibility, mobile phone addiction tendencies, emotional management training, exercise frequency, left behind experiences, and places of origin ( χ 2=82.01- 1 126.68 , all P <0.01). The results of Logistic regression analysis revealed that, the following factors were identified as significant factors influencing high level FNE among junior high school students:exercise frequency ( OR=0.21, 95%CI =0.17-0.26); parenting style ( OR=0.48, 95%CI =0.40-0.58); left behind experience ( OR=3.88, 95%CI =3.27-4.61); smartphone addiction proneness ( OR=2.19, 95%CI =0.89-0.93); self-control ability ( OR=0.91, 95%CI =0.89-0.93); and psychological flexibility ( OR=0.16, 95%CI =0.10-0.28) (all P <0.05). The AUC for the training and validation set were 0.88 (95% CI =0.87-0.89) and 0.87 (95% CI =0.85-0.89), respectively. The Hosmer-Lemeshow goodness of fit test yielded χ 2=8.57, 15.20 (both P >0.05). Conclusion The risk prediction model with high level FNE demonstrates good accuracy and can assist educators and parents in timely screening of junior high school students with high level FNE, thereby providing a basis for implementing targeted interventions.

Objective The study aims to investigate the immunological functions of the nucleocapsid (N) protein of the novel coronavirus Omicron (BA.1, BA.2) and evaluate the differences among different N proteins of mutant strains in immunogenicity. Methods By aligning sequences, the mutation sites of the Omicron (BA.1, BA.2) N protein relative to prototype strain of the novel coronavirus (Wuhan-Hu-1) were determined. The pET-28a-N-Wuhan-Hu-1 plasmid was used as template to construct pET-28a-BA.1/BA.2-N through single point mutation or homologous recombination. The three kinds of N protein were expressed in prokaryotic system, purified through Ni-NTA affinity chromatography, and then immunized into mice. The titer and reactivity of the polyclonal antibody, as well as the expression level of IL-1β and IFN-γ in mouse spleen cells, were detected using indirect ELISA and Western blot assay. Results The constructed prokaryotic expression plasmids were successfully used to express the Wuhan-Hu-1 N, BA.1 N, and BA.2 N proteins in E.coli BL21(DE3) at 37 DegreesCelsius for 4 hours. The indirect ELISA test showed that the titers of polyclonal antibody prepared by three N proteins were all 1:51 200. All three N proteins can increase the expression of IFN-γ and IL-1β cytokines, but the effect of Omicron N protein in activing two cytokines was more obvious than that of Wuhan-Hu-1 N protein. Conclusion The study obtained three new coronavirus N proteins and polyclonal antibodies, and confirmed that mutations in the amino acid sites of the N protein can affect its immunogenicity. This provides a basis for developing rapid diagnostic methods targeting N protein of different novel coronavirus variants.

PURPOSE: Traumatic brain injury (TBI) is a significant public health issue that impacts individuals all over the world and is one of the main causes of mortality and morbidity. Decompressive craniectomy is the usual course of treatment. Basal cisternostomy has been shown to be highly effective as an alternative procedure to decompressive craniectomy. METHODS: We conducted a retrospective cohort of patients who received surgery for severe TBI between January 2019 and March 2023. Inclusion criterias were patients between the ages of 18 and 70 years who met the diagnostic criteria for severe TBI at first presentation and who underwent surgical intervention. The exclusion criteria were patients who have severe multiple injuries at the time of admission; preoperative intracranial pressure > 60 mmHg; cognitive impairment before the onset of the disease; hematologic disorders; or impaired functioning of the heart, liver, kidneys, or other visceral organs. Depending on the surgical approach, the patients were categorized into decompressive craniectomy group as well as basal cisternostomy group. General data and postoperative indicators, including Glasgow coma scale, intracranial pressure, etc., were recorded for both groups of patients. Among them, the Glasgow outcome scale extended assessment at 6 months served as the primary outcome. After that, the data were statistically analyzed using SPSS software. RESULTS: The trial enrolled 41 patients (32 men and 9 women) who met the inclusion criteria. Among them, 25 patients received decompressive decompressive craniectomy, and 16 patients received basal cisternostomy. Three days postoperative intracranial pressure levels were 10.07 ± 2.94 mmHg and 17.15 ± 14.65 mmHg (p = 0.013), respectively. The 6 months following discharge Glasgow outcome scale extended of patients was 4.73 ± 2.28 and 3.14 ± 2.15 (p = 0.027), respectively. CONCLUSION Our study reveals that basal cisternostomy in patients with surgically treated severe TBI has demonstrated significant efficacy in reducing intracranial pressure as well as patient prognosis follow-up and avoids removal of the bone flap. The efficacy of cisternostomy has to be studied in larger, multi-clinical center randomized trials.

Fusion variations of neurotrophic receptor tyrosine kinase (NTRK) are oncogenic drivers in various solid tumors such as breast cancer, salivary gland carcinoma, infant fibrosarcoma, etc. Gene rearrangements involving NTRK1/2/3 lead to constitutive activation of the tropomyosin receptor kinase (TRK) domain, and the expressed fusion proteins drive tumor growth and survival. NTRK fusions are estimated to occur at a frequency of approximately 0.1% to 1% in non-small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) mutations are prevalent in NSCLC, but the frequency of EGFR G719A mutation is relatively low (about 2%), and EGFR mutations are typically mutually exclusive with NTRK fusion variants. The study presented the first documented case of lung adenocarcinoma harboring both EGFR G719A mutation and LMNA-NTRK1 fusion. A review of the literature was conducted to elucidate the role of NTRK fusion mutations in NSCLC and their relationship with EGFR mutations, aiming to enhance the understanding of NTRK fusion mutations in NSCLC.

Sepsis is a life-threatening organ dysfunction syndrome caused by a dysregulated host response to infection. Septic acute kidney injury (SAKI) is one of the most common complications of sepsis, and the occurrence of acute kidney injury (AKI) indicates that the patient's condition is critical with a poor prognosis. The traditional view holds that the main mechanism of SAKI is the reduction of renal blood flow, inadequate renal perfusion, inflammatory response, and microcirculatory dysfunction caused by sepsis, which subsequently leads to ischemia and necrosis of renal tubular cells. Recent research findings indicate that processes such as autophagy and other forms of programmed cell death play an increasingly important role. Autophagy is a programmed intracellular degradation process and is a form of programmed cell death. Cells degrade their cytoplasmic components via lysosomes, breaking down and recycling intracellular constituents to meet their metabolic needs, maintain intracellular homeostasis, and renew organelles. During SAKI, autophagy plays a crucial protective role through various mechanisms, including regulating inflammation and immune responses, clearing damaged organelles, and maintaining stability in the intracellular environment. In recent years, the role of autophagy in the pathogenesis and treatment of SAKI has received widespread attention. Research has confirmed that various intracellular signaling pathways and signaling molecules targeting autophagy [such as mammalian target of rapamycin (mTOR) signaling pathway, AMP-activated protein kinase (AMPK) signaling pathway, nuclear factor-κB (NF-κB) signaling pathway, and Sirtuins (SIRT), autophagy associated factor Beclin-1, and Toll-like receptor (TLR)] are involved in the development of SAKI. Due to the complex pathogenesis of SAKI, current treatment strategies include fluid management, infection control, maintenance of internal environment balance, and renal replacement therapy; however, the mortality remains high. In recent years, it has been found that autophagy plays a critical protective role in sepsis-mediated AKI. As a result, an increasing number of drugs are being developed to alleviate SAKI by regulating autophagy. This article reviews the latest advances in the role of autophagy in the pathogenesis and treatment of SAKI, with the aim of providing insights for the development of new drugs for SAKI patients.

【Objective】 To review the scientific research advances in the field of preschool children′s nutrition from 2012 to 2022, in order to provide reference for relevant policy formulation and further scientific exploration in this area. 【Methods】 High-quality literature published both domestically and internationally between 2012 and 2022 was retrieved through Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) database. Excel and CiteSpace software were applied to visualize the research hotspots and frontier trends. 【Results】 A total of 1 816 English articles and 110 Chinese articles were included in the analysis. The cooperation network density of research institutions and authors was found to be low. Excluding the search terms, the top three English keywords were vitamin A (0.74), intervention (0.67), obesity prevention (0.55); the top three Chinese keywords were "anemia" (0.41), "obesity" (0.38), and "nutritional status" (0.18). In Chinese and English clusters, "anemia" and "physical activity" ranked first, respectively. The latest burst words identified were "dietary pattern" and "diet quality". 【Conclusions】 The number of English literature published in the field of preschool children′s nutrition is increasing, but it has shown a downward trend in the past three years in China. There are few studies in this field in China. The research hotspots primarily focus on the nutritional status of preschool children, with less attention paid to intervention research and methodological exploration. Further research in the field of preschool children′s nutrition in China may need to focus on the external determinants of preschool children′s nutrition, such as parental education, diet and food supply.

【Objective】 To identify the risk factors for recurrence and malignant transformation (MT) in patients with low-grade glioma (LGG) after surgery. 【Methods】 The data of 163 patients who underwent LGG resection and subsequent follow-up from March 2009 to April 2019 were retrospectively collected. Patients who did not experience recurrence or MT after surgery were included in the control group (85 cases), those who experienced recurrence after surgery were included in the observation 1 group (44 cases), and those who experienced MT after surgery were included in the observation 2 group (34 cases). Based on the clinical data of the three groups of patients, their clinical characteristics were analyzed, and the risk factors and predictive value for recurrence and MT were explored using Logistic regression model and receiver operating characteristic (ROC) curve. 【Results】 There were significant differences between the control group and the observation 1 group in preoperative seizure, preoperative Karnofsky performance status (KPS) score, and surgical approach (P<0.05). There were significant differences between the control group and the observation 2 group in gender, preoperative KPS score, tumor size, and surgical approach (P<0.05). There were significant differences between the control group and the observation 1 group in isocitrate dehydrogenase (IDH) mutation, proliferating cell nuclear antigen (PCNA), matrix metalloproteinase-9 (MMP-9), cancer-testis antigen OY-TES-1, OY-TES-1 mRNA protein, tumor suppressor protein p53, mouse double minute 2 (MDM2), vascular endothelial growth factor (VEGF), or epidermal growth factor receptor (EGFR) (P<0.05). There were significant differences between the control group and the observation 2 group in PCNA, MMP-9, cancer-testis antigen OY-TES-1, OY-TES-1 mRNA protein, or VEGF (P<0.05). Logistic regression analysis showed that IDH mutation, MMP-9, and PCNA were independent risk factors for LGG recurrence (P<0.05), while VEGF, MMP-9, and PCNA were independent risk factors for LGG MT (P<0.05). The area under curve (AUC) of PCNA, MMP-9 and IDH mutation for predicting LGG MT after surgery was 0.744, 0.790, and 0.799, respectively. The AUC of PCNA, MMP-9, and VEGF for predicting LGG recurrence after surgery was 0.729, 0.750, and 0.900, respectively. 【Conclusion】 This study found that IDH mutation, MMP-9 and PCNA were independent risk factors for LGG recurrence, while VEGF, MMP-9 and PCNA were independent risk factors for LGG MT by retrospectively analyzing the clinical data and protein expression of 163 patients with LGG after surgery. These proteins have high accuracy in predicting LGG recurrence and MT after surgery. Therefore, the proteins may play an important role in the biological behavior and treatment effect of LGG, and can be used as reference indicators for prognosis evaluation and individualized treatment of LGG patients after surgery.

Objective:To evaluate and compare dermoscopic features of toenail psoriasis and fingernail psoriasis.Methods:Between June 2020 and January 2022, 61 patients with confirmed toenail psoriasis and 80 with confirmed fingernail psoriasis were enrolled from the Department of Dermatology of Peking University First Hospital. Dermoscopy was performed on 139 affected toenails and 158 affected fingernails among the psoriasis patients, and dermoscopic characteristics were analyzed between the two groups by using the chi-square test.Results:The most common dermoscopic feature of nail psoriasis was pitting (223/297, 75.08%), followed by splinter haemorrhages (164/297, 55.22%), subungual hyperkeratosis (133/297, 44.78%), oil drop sign (126/297, 42.42%), complete onycholysis (121/297, 40.74%), linear margin of the proximal onycholysis (107/297, 36.03%) and linear erythema at the margin of the onycholysis (77/297, 25.93%). Compared with the patients with fingernail psoriasis, those with toenail psoriasis more commonly presented with subungual hyperkeratosis (81[58.27%] vs. 52[32.91%], P < 0.001), punctate/blocky haemorrhages (22[15.83%] vs. 11[6.96%], P < 0.05), longitudinal striae (34[24.46%] vs. 10[6.33%], P < 0.001), longitudinal nail splitting (24[17.27%] vs. 9[5.70%], P < 0.01), brown discoloration (14[10.07%] vs. 2[1.27%], P < 0.01), transverse grooves (17[12.23%] vs. 1[0.63%], P < 0.001) and leukonychia (10[7.19%] vs. 1[0.63%], P < 0.01) ; compared with the patients with toenail psoriasis, those with fingernail psoriasis more commonly presented with splinter haemorrhages (100[63.29%] vs. 64[46.04%], P < 0.01), oil drop sign (81[51.27%] vs. 45[32.37%], P < 0.01), linear erythema at the margin of the onycholysis (55[34.81%] vs. 22[15.83%], P < 0.001), partial onycholysis (50[31.65%] vs. 19[13.67%], P < 0.001) and red spots in the lunula (36[22.78%] vs. 12[8.63%], P < 0.01) . Conclusion:The dermoscopic features of toenail psoriasis were quite different from those of fingernail psoriasis, and features such as subungual hyperkeratosis, longitudinal streaks, and brown discoloration were more commonly presented in patients with toenail psoriasis.
