ObjectiveTo explore the construction and evaluation methods of a rat model of acute myocardial infarction(AMI) with Qi and Yin deficiency syndrome established by sleep deprivation combined with coronary artery ligation. MethodsThirty-six SD rats were randomly divided into a normal group(n=6), a myocardial infarction group(model A group, n=10), an acute sleep deprivation+myocardial infarction group(model B group, n=10), and a chronic sleep deprivation+myocardial infarction group(model C group, n=10) according to body weight. Rats in the normal group were not treated, rats in the model A group underwent only ligation of the left anterior descending coronary artery, rats in the model B group were sleep deprived for 96 h and then underwent ligation of the left anterior descending coronary artery, and rats in the model C group were sleep deprived for an additional 48 h each week with a 24 h rest period as one cycle for three weeks on the basis of the model B group. After coronary artery ligation in the model C group, the first week was defined as the starting point of the first sleep deprivation cycle, and indexes were tested weekly for rats in each group for 3 weeks. Electrocardiogram was used to determine the ligation of the left anterior descending coronary artery in rats, and small animal echocardiography was used to evaluate the cardiac function. The levels of serum creatine kinase(CK), creatine kinase isoenzyme(CK-MB), lactate dehydrogenase(LDH), cardiac troponin T(cTnT), interleukin-18(IL-18), and tumor necrosis factor-α(TNF-α) were detected by biochemical assays, and hematoxylin-eosin(HE) staining was used to evaluate the pathological changes of myocardial tissue in rats. The syndrome indicators of Qi and Yin deficiency were evaluated by general state and body weight, grip strength, facial temperature, paw temperature, rectal temperature, salivary flow rate, open field test, tongue color[red(R), green(G), and blue(B)] values, pulse amplitude changes, and enzyme-linked immunosorbent assay(ELISA) for the detection of expression levels of cyclic adenosine monophosphate(cAMP), cyclic guanosine monophosphate(cGMP), rat serum corticotropin-releasing factor(CRF), adrenocorticotropic hormone(ACTH), triiodothyronine(T3), tetraiodothyronine(T4), and corticosterone(CORT) in serum. ResultsIn terms of disease indicators, compared with the normal group, the ST segment of the electrocardiogram in each model group was significantly elevated, the echocardiographic parameters were decreased, the contents of myocardial enzymes and inflammatory factors were increased(P<0.01), and the myocardial tissue in the infarcted area was significantly damaged. In terms of syndrome indicators, compared with the normal group, the body weight of rats in the model B and C groups decreased at each time point, the grip strength of each model group decreased, the total distance traveled and the number of entries into the center in the open field test decreased, the immobility time increased, the facial and rectal temperatures of rats in the model B and C groups increased, the salivary flow rate of each model group decreased, the tongue color was bright red or light, the tongue body was dry or smooth like a mirror, lacking of moisture sensation, the R, G and B values of the tongue surface increased, the pulse amplitude changes decreased, and the contents of T3 and T4 increased, while the expressions of cAMP, CRF, ACTH and CORT in the model B and C groups increased(P<0.05, P<0.01). ConclusionContinuous sleep deprivation for 96 h in a multi-platform method combined with coronary artery ligation can construct a rat model of AMI with Qi and Yin deficiency syndrome, and the syndrome manifestations can be maintained for 3 weeks.

ObjectiveTo explore the feasibility, evaluation methods and metabolic differences of high-fat diet(HFD) combined with myocardial ischemia-reperfusion injury(MIRI) to establish a rat model of myocardial ischemia-reperfusion with phlegm and blood stasis blocking collaterals syndrome(PBSBCS). MethodsThirty-two SD rats were randomly divided into the sham operation, HFD, MIRI, and MIRI+HFD groups. Rats in the sham operation and MIRI groups were fed a standard diet(regular chow), while the HFD and MIRI+HFD groups received a HFD for 10 weeks. Rats in the MIRI and MIRI+HFD groups underwent myocardial ischemia-reperfusion surgery, while the sham operation group underwent only thread placement without ligation. Cardiac function was assessed via small-animal echocardiography, including left ventricular ejection fraction(EF), left ventricular fractional shortening(FS), cardiac output(CO), and stroke volume(SV). Serum levels of creatine kinase(CK), CK-MB, triglyceride(TG), total cholesterol(TC), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), lactate dehydrogenase(LDH), endothelin-1(ET-1), endothelial nitric oxide synthase(eNOS), tumor necrosis factor-α(TNF-α), interleukin-18(IL-18), oxidized LDL(ox-LDL), and cardiac troponin T(cTnT) were measured by biochemical assays and enzyme-linked immunosorbent assay(ELISA). Myocardial histopathology was evaluated via hematoxylin-eosin(HE) staining, while myocardial infarction and no-reflow area were assessed using 2,3,5-triphenyltetrazolium chloride(TTC), Evans blue, and thioflavin staining. Changes in syndrome characteristics[body weight, tongue surface red-green-blue [RGB] values, and pulse amplitude] of PBSBCS were recorded. Serum differential metabolites were analyzed by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS). ResultsCompared with the sham operation group, the HFD and MIRI+HFD groups showed significant increases in body weight(P<0.01), RGB values and pulse amplitude decreased in the HFD, MIRI and MIRI+HFD groups, TC, TG, LDL-C and ox-LDL levels increased in the HFD and MIRI+HFD groups, while HDL-C decreased. Blood perfusion peak time and myocardial no-reflow area increased, serum eNOS level decreased, and CK-MB, LDH, and cTnT activities increased in the HFD, MIRI and MIRI+HFD groups(P<0.05, P<0.01). Whole blood viscosity was increased in the HFD group at medium shear rate, and in the MIRI and MIRI+HFD groups at low, medium and high shear rates(P<0.05, P<0.01). Platelet aggregation rate increased in the MIRI and MIRI+HFD groups, accompanied by elevated ET-1, TNF-α, and IL-18 levels, reduced cardiac function indices, expanded myocardial no-reflow and infarction areas, and increased serum CK, CK-MB, LDH, and cTnT activities(P<0.05, P<0.01). Compared with the MIRI group, the HFD and MIRI+HFD groups showed significant increase in body weight, TC, TG, LDL-C and ox-LDL levels, and significant decrease in HDL-C content(P<0.01). The MIRI+HFD group showed decrease in RGB values and pulse amplitude, and an increase in whole blood viscosity, platelet aggregation, blood perfusion peak time, myocardial no-reflow and infarction areas, elevated ET-1, TNF-α and IL-18 levels, decreased eNOS content, EF and SV, increased serum CK, CK-MB and cTnT activities, and worsened myocardial pathology(P<0.05). Compared with the HFD group, the MIRI+HFD group showed similar aggravated trends(P<0.05, P<0.01). Metabolomics results showed that 34 potential biomarkers involving 13 common metabolic pathways were identified in the MIRI+HFD group compared with the sham operation group. ConclusionThe MIRI group resembles blood stasis syndrome in hemodynamics and myocardial injury, and the HFD group mirrors phlegm-turbidity syndrome in lipid profiles and tongue characteristics. While the MIRI+HFD group aligns with PBSBCS in comprehensive indices, effectively simulating clinical features of coronary heart disease(CHD), which can be used for the evaluation of the pathological mechanism and pharmacodynamics of CHD with PBSBCS.

ObjectiveTo investigate the preparation method of a mouse model of cerebral infarction with Qi and Yin deficiency syndrome induced by streptozotocin(STZ) combined with the photochemical method, and to evaluate the biological basis of the established model. MethodsForty C57B6/J mice were randomly divided into the normal and model groups, with 20 mice in each group. The normal group received no treatment, while the model group was injected intraperitoneally with 55 mg·kg-1 of STZ once a day for 5 days. Fourteen days post-STZ induction, 10 mice from the normal group were randomly taken into the photochemical group, while 10 mice from the model group were randomly taken into the STZ+photochemical group. Rose Bengal solution injection combined with 520 nm laser irradiation was used to cause thrombosis and induce cerebral infarction in mice. Syndrome indexes for Qi and Yin deficiency were assessed by general state observation, body weight, grip strength, rectal temperature, behavioral experiments, energy metabolism, tongue color[red(R), green(G), blue(B)] values, adenosine triphosphate(ATP) content, corticotropin-releasing factor(CRF) and triiodothyronine(T3) levels. The pathological changes of cerebral infarction in mice were evaluated by detecting serum superoxide dismutase(SOD), interleukin-1β(IL-1β), IL-6, and tumor necrosis factor-α(TNF-α) levels in combination with Bederson score. Finally, the endogenous metabolites in mice were detected by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS), and multivariate statistical analysis was performed by partial least squares-discriminant analysis(PLS-DA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). The data filtering criteria were set as variable importance in the projection(VIP) value> 1, fold change(FC)<0.8 or FC>1.2, P<0.05, to obtain differential metabolites. Then MetaboAnalyst 3.0 was utilized for pathway enrichment analysis of the differential metabolites, aiming to explore the metabolic profile changes and biological basis of mice with Qi and Yin deficiency syndrome of cerebral infarction. ResultsRegarding the syndrome indicators, compared with the normal group, the mice in the model group had lower body weight, higher rectal temperature, lower limb motor ability and energy metabolism efficiency, lower ATP content, lower R, G and B values of the tongue surface, and lower speed of blood glucose regression(P<0.05, P<0.01). As for the disease indicators, compared with the normal group, the Bederson scores of the photochemical group and the STZ+photochemical group increased, the grip strength decreased, the SOD level decreased, and the levels of inflammatory factors increased(P<0.05). The results of metabolomics showed that a good separation pattern of components was observed among mice in each group, with significant differences in components. Identification of MS data revealed a total of 44 differential metabolites in mice with Qi and Yin deficiency syndrome of cerebral infarction. Among them, 32 metabolites were up-regulated, mainly including triglycerides, diglycerides, phospholipids, and ceramides. And 12 metabolites were down-regulated, mainly including amino acid and phosphate metabolites. Pathway enrichment analysis of the above differential metabolites indicated that the metabolic pathways were mainly enriched in folate biosynthesis, terpenoid skeleton biosynthesis, glycerophospholipid metabolism, vitamin B6 metabolism, glycerolipid metabolism and sphingolipid metabolism. These pathways were involved in multiple processes such as lipid transport, insulin resistance, and energy metabolism. ConclusionThe method of STZ injection combined with photochemical induction can successfully establish a mouse model of cerebral infarction with Qi and Yin deficiency syndrome, and intervene in vivo processes such as folate biosynthesis, glycerophospholipid metabolism, and glycerolipid metabolism.

OBJECTIVES:
To evaluate the efficacy of molecular targeted agents in children with progressive pediatric low-grade gliomas (pLGG).
METHODS:
A retrospective analysis was conducted on pLGG patients treated with oral targeted therapies at the Department of Pediatrics, Beijing Shijitan Hospital, Capital Medical University, from July 2021. Treatment responses and safety profiles were assessed.
RESULTS:
Among the 20 enrolled patients, the trametinib group (n=12, including 11 cases with BRAF fusions and 1 case with BRAF V600E mutation) demonstrated 4 partial responses (33%) and 2 minor responses (17%), with a median time to response of 3.0 months. In the vemurafenib group (n=6, all with BRAF V600E mutation), 5 patients achieved partial responses (83%), showing a median time to response of 1.0 month. Comparative analysis revealed no statistically significant difference in progression-free survival rates between the two treatment groups (P>0.05). The median duration of clinical benefit (defined as partial response + minor response + stable disease) was 11.0 months for vemurafenib and 18.0 months for trametinib. Two additional cases, one with ATM mutation treated with olaparib for 24 months and one with NF1 mutation receiving everolimus for 21 months, discontinued treatment due to sustained disease stability. No severe adverse events were observed in any treatment group.
CONCLUSIONS
Molecular targeted therapy demonstrates clinical efficacy with favorable tolerability in pLGG. Vemurafenib achieves high response rates and induces early tumor shrinkage in patients with BRAF V600E mutations, supporting its utility as a first-line therapy.

Objective:To explore the prognosis of patients with gastric cancer peritoneal metastasis (PM) receiving programmed cell death-1 (PD-1) antibody therapy, and investigate the biomarkers that affect the prognosis of anti-PD-1 therapy.Methods:This restrospecific study collected the clinic-pathological data of 56 patients with peritoneal metastasis of gastric cancer who received first-line treatment in the Nanjing Drum Town Hospital from March 2020 to September 2023, among which 41 had received anti-PD-1 immunotherapy and 15 hadn't. The relationship between overall survival (OS) and anti-PD-1 immunotherapy was evaluated by Kaplan-Meier analysis. The relationship between baseline peripheral blood indicators and treatment response of patients with anti-PD-1 treatment was analyzed using unpaired t-test. Subsequently, the Cox proportional risk regression model was used to explore the clinical prognostic factors that may affect anti-PD-1 immunotherapy by univariate and multivariate analysis. The clinical prognostic factors included baseline data and baseline peripheral blood indexes such as anti-PD-1 treatment lines, Eastern Cooperative Oncology Group performance status (ECOG PS), combined positive score (CPS), expression of human epidermal growth factor receptor 2 (Her-2), EBER status, pathological types, other metastatic lesions, ascites content before immunotherapy, with or without abdominal drainage during anti-PD-1 treatment, blood lipid indicators, inflammatory indicators, and tumor indicators. Results:Kaplan-Meier survival statistics showed similar OS (15.9 vs. 15.2 months, P=0.600) in patients with anti-PD-1 therapy compared to those without anti-PD-1 therapy. Patients with baseline high-density lipoprotein (HDL) ≥0.97 mmol/L ( n=22) demonstrated a significantly longer median OS compared to those with HDL<0.97 mmol/L (15.2 vs. 13.5 months; P=0.018). Similarly, the cohort with apolipoprotein A1 (ApoA1) levels ≥0.86 g/L ( n=21) showed superior survival outcomes, with a median OS of 17.7 months versus 12.3 months in the ApoA1<0.86 g/L group ( n=20; P=0.006). In contrast, elevated baseline alpha-fetoprotein (AFP) levels ( n=2) were associated with markedly reduced survival (median OS: 5.7 vs. 15.2 months in normal AFP group, n=37; P=0.005). Notably, elevated pretreatment ApoA1 levels correlated with enhanced immunotherapy response ( P=0.017). Multivariate Cox regression analysis revealed that ApoA1 deficiency (≥0.86 g/L) independently predicted better OS following PD-1 antibody therapy ( HR=0.35, 95% CI: 0.12-0.98, P=0.046) in gastric cancer patients with PM. Conclusions:In our study, it is first proposed that ApoA1 could be a significant predictor of the survival advantages of immunotherapy in gastric cancer patients with PM.
