ObjectiveThis paper aims to investigate the differential mechanisms underlying the staged therapeutic effects of Qijia Rougan formula on liver fibrosis using proteomic technology. MethodsThe staged rat model of liver fibrosis was established by subcutaneous injection of carbon tetrachloride (CCl4) and olive oil. One hundred and four SD rats were randomized into thirteen groups:a normal group,a two-week model group,a four-week model group,a six-week model group,an eight-week model group,a two-week Qijia Rougan formula group,a four-week Qijia Rougan formula group,a six-week Qijia Rougan formula group,an eight-week Qijia Rougan formula group,a two-week compound Biejia Ruangan tablet group,a four-week Compound Biejia Ruangan Tablet group,a six-week Compound Biejia Ruangan Tablet group,and an eight-week compound Biejia Ruangan tablet group. After two weeks of drug intervention,liver tissue and abdominal aortic blood samples were collected from the rats for testing. Hematoxylin-eosin (HE) staining,Masson staining,and Picro Sirius red staining were used to observe pathological damage and collagen fiber deposition in liver tissues. Immunohistochemistry (IHC) was employed to detect the contents of fibrosis markers in liver tissues. The contents of liver function indicators in the serum were measured using a fully automated biochemical analyzer,and the levels of liver fibrosis indicators in the serum were assessed by enzyme-linked immunosorbent assay (ELISA). Liver tissues from the normal group,each model group,and each Qijia Rougan formula group were subjected to label-free quantitative proteomic analysis to identify differential proteins among the groups,with key proteins validated by Western blot. Finally,bioinformatics analysis was performed on the differential proteins. Results(1) The staged rat model of liver fibrosis constructed with CCl4 and olive oil showed pathological results at the 2nd,4th,6th,and 8th weeks of modeling that were consistent with the Metavir standards for the F1,F2,F3,and F4 stages. Compared with those in the normal control group,the protein expressions of α-smooth muscle actin (α-SMA) and Collagen Ⅰ were significantly increased in each stage (P<0.05). The levels of liver function indicators in the serum,including alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),direct bilirubin (DBIL),and total bilirubin (TBil) in each model group,were significantly elevated in each stage (P<0.01). The levels of liver fibrosis indicators in the serum,including procollagen Ⅲ peptide (PⅢP),type Ⅳ collagen(Ⅳ-C),hyaluronic acid (HA),and laminin (LN) in each model group,were significantly increased in each stage (P<0.05,P<0.01). This study successfully established a staged rat model of liver fibrosis. (2) Compared with the model groups at each stage,the administration groups showed a reduction in hepatocyte ballooning degeneration,a more orderly arrangement of hepatocytes,and a decrease of inflammatory cell infiltration. The blue-stained collagen fibers became significantly thinner and finer,with reduced and narrowed fibrous septa. The areas of collagen fibers and Picro Sirius red staining were reduced (P<0.05). The positive areas of α-SMA and Collagen Ⅰ expression were significantly decreased (P<0.05). The levels of ALT,AST,ALP,DBIL,and TBil in the rats of the model groups at each stage were significantly reduced (P<0.05,P<0.01). The levels of PⅢP,Ⅳ-C,HA,and LN in the rats of the model groups at each stage were significantly decreased (P<0.05). Among these,the improvements in all indicators were most significant in the F3 stage (P<0.01).(3) The proteomic results show that a total of 165 differential proteins exhibit a callback trend when comparing the model groups at four stages with the normal group,and when comparing the Qijia Rougan formula group with the model group. Western blot analysis reveals that the levels of NAD(P)H:quinone oxidoreductase 1 (NQO1),mitogen-activated protein kinase 1 (MAPK1),arginase 1 (Arg1),and glutathione S-transferase α1 (GSTA1) were consistent with the proteomic results. Bioinformatics results reveal that 165 differentially expressed proteins are enriched in multiple signaling pathways. Notably,signaling pathways such as drug metabolism-cytochrome P450,arginine biosynthesis,and the peroxisome proliferator-activated receptor (PPAR) signaling pathway were found to be closely associated with liver fibrosis,suggesting that the Qijia Rougan formula may exert its staged regulatory effects on liver fibrosis by regulating these pathways. ConclusionThe Qijia Rougan formula may achieve staged regulation of liver fibrosis by regulating drug metabolism-cytochrome P450,arginine biosynthesis,and the PPAR signaling pathway.

Purpose:
This study aimed to evaluate the safety and efficacy of gemcitabine and cisplatin (GP) regimen in combination with immune checkpoint inhibitor sintilimab as neoadjuvant therapy for muscle-invasive bladder cancer (MIBC) patients and the feasibility of the following selective bladder sparing surgery.
Materials and Methods:
Patients with histopathologically confirmed urothelial carcinoma without distant metastases (T2-4a, N ≤ 1, M0, American Joint Committee of Cancer 8th) and with adequate organ function will be enrolled. The therapeutic regimen was sintilimab 200 mg once on day 8, gemcitabine 1,000 mg/m2 and cisplatin 35 mg/m2 once on days 1 and 8, every 21 days for four cycles. The primary endpoint was pathologic complete response (pCR, pT0N0) rate. The secondary end points were ypT < 2 rate, R0 resection rate, event-free survival, and safety.
Results:
From May 4, 2020, to May 20, 2023, 55 patients were enrolled. Forty-six patients were evaluated for efficacy. Among the 42 patients who underwent surgery, 16 patients (38.0%) achieved pCR. Thirty-three patients (78.6%) achieved pT < 2. With a median follow-up of 15.7 months, the 1-year event-free survival was 91.3%. Notwithstanding the poor pathological baseline characteristic of a high T3-T4a proportion (39.1%), a promising bladder preservation (including 22 patients transurethral resection of bladder tumor, 5 patients partial cystectomy, and 4 surveillances) rate was achieved (67.4%). The most common grade ≥ 3 treatment-related adverse events was neutropenia (n=15, 27.3%), which was related to chemotherapy. There were no grade 3 immune-related adverse events.
Conclusion
Neoadjuvant GP plus sintilimab is a promising regimen for MIBC patients, with relatively high pT < 2 rate and triggering the emerging roles for the multi-disciplinary team decision-making for bladder sparing surgery.

Objective To understand mosquito density, species composition, and seasonal variations around the Beijing Capital International Airport(BCIA)and provide scientific evidence for mosquito-borne disease prevention and control. Methods Meteorological data were collected from 2016 to 2022, and mosquito density was monitored at seven surveillance sites around the BCIA from May to October each year using CO2-baited mosquito traps to analyze the relationship between mosquito density and meteorological factors. Results In total,68 518 female mosquitoes were captured, with a mosquito density of 10.20 per light · hour. The dominant species was Culex pipiens pallens(73.90%), followed by Aedes albopictus(9.71%)and Ae. vexans(9.29%);the mosquito density was highest in 2016(14.8 per light·hour)and lowest in 2022(4.46 per light·hour). Significant statistical differences were observed in mosquito density among different species(F=18.118, P<0.05). The density of Cx. pipiens pallens and other mosquito species showed a mutually exclusive trend; the peak of mosquito density varied based on years and habitats, with significant statistical differences in mosquito density among different habitats(F=8.504, P<0.05). The highest mosquito density was observed near the Wenyu River(21.50 per light·hour), whereas the lowest was recorded at the BCIA construction site(2.44 per light· hour). The monthly average temperature(r=0.595), monthly average highest temperature(r=0.575), and monthly average lowest temperature(r=0.624)showed moderate positive correlations, whereas the monthly average air pressure(r=-0.484)showed a moderate negative correlation. The monthly average minimum temperature was included in the regression model(F=25.575, P<0.000), and the equation Y=1.029X4-8.181 was used. The monthly average air pressure 2 months prior(b=-2.418, β=-1.619, P<0.05)and the monthly average relative humidity(b=-0.739, β=-1.201, P<0.05)significantly negatively predicted the mosquito density. Notably, the regression equation used was y=2526.170+(-2.418)X9+(-0.739)X13. The exposure-response analysis revealed that the density of mosquitoes was not linearly related to the average monthly air pressure, rainfall, and duration of sunshine. Conclusions The dominant mosquito species around the BCIA was Cx. pipiens pallens, Ae. albopictus, and Ae. vexans. During the control of Cx. pipiens pallens, the impact on other mosquito species must also be considered. Environmental management, breeding sites, and scientific use of pesticides should be prioritized based on the activity periods of mosquitoes. Further studies on mosquitoes and meteorological factors should be conducted to provide references and novel avenues for mosquito control.

In modern society, the comorbidity of insomnia with amnesia has shown a significantly increasing incidence and become increasingly severe, emerging as a public health issue that endangers people's physical and mental health and quality of life. Anmei Dan (AMD), originally recorded in the Shishi Milu by CHEN Shiduo in the Qing Dynasty, possesses profound theoretical foundations and distinct clinical advantages in ameliorating insomnia with amnesia. Basic research has unequivocally confirmed its definite therapeutic effects on insomnia with amnesia and revealed partial mechanisms. AMD is therefore a veritable classic prescription embodying the principle of treating different diseases with the same method for insomnia and amnesia. However, few researchers have reviewed the related research progress. This article systematically summarized the theoretical connotations of traditional Chinese medicine in treating insomnia with amnesia, delineated the multi-component material basis of AMD in ameliorating insomnia with amnesia (including various chemical components such as ginsenosides, jujubosides, and salvianolic acids), and evaluate its multi-dimensional clinical efficacy (e.g., prolonging total sleep time, improving sleep efficiency, and enhancing memory). Moreover, it systematically summarizes the multi-pathway mechanisms of action. The results indicate that AMD has a clear material basis, definite clinical efficacy, and a favorable safety profile in ameliorating insomnia and amnesia. AMD may exert the therapeutic effect by regulating sleep-wake rhythms, enhancing synaptic plasticity, inhibiting neuroimmune inflammation, and modulating autophagy, oxidative stress, and energy metabolism. In conclusion, AMD exerts synergistic effects through multi-component, multi-dimensional, and multi-pathway approaches, serving as an important prescription for enriching and developing the theory of treating different diseases with the same method for insomnia with amnesia.

ObjectiveTo investigate the therapeutic effect of wall-broken ganoderma lucidum spore powder (GLS) on a mouse model of hepatocellular carcinoma and to explore its underlying mechanism. MethodsFifty 2-week-old C57BL/6J mice were divided into a control group, a model group and low, medium and high-dose GLS groups(0.25, 0.5, 1.0 g/kg ), with 10 mice in each group. A DEN/CCL4 mouse hepatocellular carcinoma model was established, and GLS was administered by gavage starting from the 8th week, once a day for 14 weeks. At the end of the final administration, the number of liver nodules was observed , and the serum alpha-fetoprotein (AFP) was detected using enzyme-linked immunosorbent assay. The content of catalase (CAT) in serum and liver tissue was determined by ammonium molybdate method. The content of reduced glutathione (GSH) in serum and liver tissue was measured by microplate assay. The content of glutathione peroxidase (GSH-PX) in serum and liver tissue was detected by colorimetric method. Immunohistochemistry (IHC-P) was employed to detect the protein expression of proliferating cell nuclear antigen (PCNA). R eal-time fluorescence quantitative polymerase chain reaction was utilized to detect the relative expression of nuclear factor E2-related factor 2 (Nrf2), Kelch-like epichlorohydrin-associated protein 1 (Keap1), NAD(P)H quinone oxidoreductase 1 (Nqo1), heme oxygenase-1 (Ho-1) and glutamate cysteine ligase catalytic subunit (Gclc) mRNA. ResultsCompared with the control group, the content of serum AFP were significantly higher in the model group (P<0.01), while the contents of CAT, GSH and GSH-PX in liver and serum were significantly lower in the model group (P<0.01). The relative expression of Keap1 and Nqo1 mRNA was significantly higher (P<0.01), the relative expression of Nrf2, Ho-1, Gclc mRNA relative expression was significantly lower (P<0.01), and the positive expression rate of PCNA was significantly higher (P<0.01). Compared with the model group, the total number of liver nodules and content of serum AFP in the administered group were significantly lower (P<0.01), and the contents of CAT, GSH, and GSH-PX in the liver and serum of mice significantly increased (P<0.05 or P<0.01). The expression of Keap1 and Nqo1 mRNA significantly decreased (P<0.05). The expression of Nrf2, Ho-1 and Gclc mRNA significantly increased (P<0.05), and positive expression rate of PCNA significantly decreased (P<0.01). ConclusionGLS has a significant protective effect on DEN/CCL4 -induced mouse hepatocellular carcinoma model, and the mechanism of action is related to the regulation of oxidative stress in mouse liver.

ObjectiveTo observe the effects of Xiere Xingpi Yin (XRXPY) on the body mass and body fat distribution in patients with simple obesity, and to preliminarily explore whether the mechanism involves the regulation of specific obesity-related microRNAs (miRNAs). MethodsA randomized controlled trial design was employed to recruit patients with simple obesity diagnosed with the traditional Chinese medicine (TCM) syndrome of dampness-heat accumulating in the spleen. Using a randomized controlled trial design, 95 patients with simple obesity of dampness-heat encumbering the Spleen syndrome were recruited, after 3 were excluded, 92 were randomly assigned in a 1∶1 ratio by means of a random number table. On the basis of lifestyle intervention, the observation group received XRXPY granules, while the control group received a placebo. Serum samples and TCM symptom scores were collected before and after the 12-week observation period. Differences in body mass loss, body composition, lipid metabolism, and TCM symptom scores were compared between the groups. An obesity-related miRNA dataset was constructed by searching the Human MicroRNA Disease Database. Library construction, sequencing, and quality control were performed on 6 selected patients from each group to screen the differentially expressed miRNAs. The intersection of these miRNAs with the obesity-related miRNAs was verified by bioinformatics and correlation analysis. ResultsBaseline characteristics were comparable between the two groups before treatment. A total of 86 patients completed the study (42 cases in the observation group and 44 cases in the control group). The proportion of patients achieving ≥5% body weight reduction was significantly higher in the observation group than in the control group 81.0% (34/42) vs. 43.2% (19/44) (χ2=12.963, P<0.01). Compared with baseline within the observation group, body weight, waist circumference, and TCM syndrome score were significantly decreased (P<0.01), as were body fat percentage (P<0.01) and serum triglyceride level (P<0.05). Compared with the control group after treatment, waist circumference and TCM syndrome score were significantly lower in the observation group (P<0.01), and body weight showed a trend toward reduction. When changes from baseline were compared between the two groups, the magnitudes of decrease in body weight, waist circumference, and TCM syndrome score were all significantly greater in the observation group than in the control group (P<0.01). With respect to safety, no serious adverse events occurred in either group and no participant discontinued the study because of adverse events. Compared with baseline, alanine aminotransferase levels decreased significantly in both the control and observation groups (P<0.01), and urea decreased significantly in the observation group (P<0.01), indicating a favorable safety profile. Sequencing identified nine differentially expressed miRNAs. After intersecting with the obesity-related miRNA dataset (187 miRNAs), 3 miRNAs were identified: miR-221 (log2FC=-6.62, P=0.009), miR-29a (log2FC=6.33, P=0.016), and miR-10b (log2FC=-5.91, P=0.029). A total of 262 target genes of the 3 miRNAs were identified, which were significantly enriched in 67 pathways, including the lysine degradation pathway (P=0.001). Correlation analysis revealed a positive correlation between miR-221 and triglycerides (r=0.46, P=0.027), a negative correlation between miR-29a and waist-to-hip ratio (r=-0.41, P=0.047), and positive correlations of miR-10b with body fat percentage (r=0.49, P=0.014) and waist circumference (r=0.44, P=0.032). ConclusionXRXPY combined with lifestyle intervention can effectively reduce the body mass and improve body composition. The underlying mechanism may involve the regulation of the lysine degradation pathway via miR-221, miR-29a, and miR-10b, though further verification is required.

ObjectiveBased on ultra-high performance liquid chromatography-quadrupole-electrostatic field orbital trap-linear ion-trap mass spectrometry(UPLC-Orbitrap Fusion Lumos Tribrid-MS), the plasma concentration of ziyuglycoside Ⅰ was determined at different time points after oral administration, and its pharmacokinetic characteristics in normal rats and rats with acute kidney injury were compared. MethodsRats were randomly divided into normal group and model group, the model group received intraperitoneal cisplatin(10 mg·kg-1) to establish the acute kidney injury model, the normal group was given the same volume of saline. After successful modeling, rats in the normal and model groups were randomly divided into the normal low, medium and high dose groups(2.5, 5, 7.5 mg·kg-1) and the model low, medium and high dose groups(2.5, 5, 7.5 mg·kg-1), 6 rats in each group, and the plasma was collected at different time points after receiving the corresponding dose of ziyuglycoside Ⅰ. Then, the concentration of ziyuglycoside Ⅰ in rat plasma was determined by UPLC-Orbitrap Fusion Lumos Tribrid-MS, and the drug-time curve was poltted. The pharmacokinetic parameters were calculated by Kinetica 5.1 software, and the differences in pharmacokinetic parameters between different administration groups were compared by independent sample t-test with SPSS 22.0. ResultsThe pharmacokinetic results showed that after receiving the different doses of ziyuglycoside Ⅰ, its concentration increased first and then decreased, and all of them reached the maximum plasma concentration at about 0.5 h. The area under the curve(AUC0-t) and mean retention time(MRT0-t) of normal and model rats increased with the increased dose, and the clearance(CL) decreased with the increasing dose. Compared with the normal group, the AUC0-t was significantly increased(P<0.01), peak concentration(Cmax) and CL decreased in model rats at different doses, indicating that the physiological state of the rats could affect the absorption and elimination of ziyuglycoside Ⅰ in vivo. ConclusionThe pharmacokinetic characteristics of ziyuglycoside Ⅰ are quite different in normal rats and acute kidney injury model rats, which may be due to the change of the body environment in the pathological state, then lead to changes in absorption and metabolic processes.

BACKGROUND:At present,osteoarthritis has become a major disease affecting the quality of life of the elderly,and the therapeutic effect is poor,often focusing on preventing the disease process,and the pathogenesis of osteoarthritis is still not fully understood.Bioinformatics analysis was carried out to explore the main pathogenesis of osteoarthritis and related mechanisms of gene coding regulation. OBJECTIVE:To screen core differential genes with a major role in osteoarthritis by gene expression profiling. METHODS:Datasets were downloaded from the Gene Expression Omnibus(GEO):GSE114007,GSE117999,and GSE129147.Differential genes in the GSE114007 and GSE117999 data collections were screened using R software,performing differential genes to weighted gene co-expression network analysis.The module genes most relevant to osteoarthritis were selected to perform protein interaction analysis.Candidate core genes were selected using the cytocape software.The candidate core genes were subsequently subjected to least absolute shrinkage and selection operator regression and COX analysis to identify the core genes with a key role in osteoarthritis.The accuracy of the core genes was validated using an external dataset,GSE129147. RESULTS AND CONCLUSION:(1)A total of 477 differential genes were identified,265 differential genes associated with osteoarthritis were obtained by weighted gene co-expression network analysis,and 8 candidate core genes were identified.The least absolute shrinkage and selection operator regression analysis finally yielded a differential gene ASPM with core value that was externally validated.(2)It is concluded that abnormal gene ASPM expression screened by bioinformatics plays a key central role in osteoarthritis.

Objective:To evaluate the safety and clinical efficacy of enteral nutrition (EN) initiated within 24 h after heart transplantation in pediatric patients.Methods:A retrospective cohort study was conducted. Clinical data from 16 pediatric heart transplant recipients at the Seventh Medical Center of the Chinese People′s Liberation Army General Hospital between October 2022 and October 2024 were collected, including demographics, anthropometric measurements, biochemical markers, cytokine levels, and clinical outcomes. Based on the timing of EN initiation, the patients were divided into EN-initiated within 24 h and EN-initiated after 24 h 2 groups. Demographic data, preoperative extracorporeal membrane oxygenation (ECMO) support, physical examination indicators, laboratory parameters, and cytokine levels were compared between groups using independent samples t-test, Mann-Whitney U test, Fisher′s exact probability test. Results:The cohort comprised 16 patients (10 males and 6 females) with an age of (12.5±1.9) years. The EN-initiated within 24 h group comprised 6 cases, and the EN-initiated after 24 h group comprised 10 cases. No significant difference was observed between the two groups in age, preoperative body mass index Z-score, preoperative ECMO support, physical examination indicators, laboratory parameters (total protein, albumin, hemoglobin), or cytokine levels (all P>0.05). Compared to the EN-initiated after 24 h group, the EN-initiated within 24 h group exhibited a shorter intensive care unit stay ( t=2.65, P<0.05) and shorter mechanical ventilation duration ( t=2.23, P<0.05) than EN-initiated after 24 h group. Total hospitalization length had no significant difference ( P>0.05). At 72 h post-transplant, the EN-initiated within 24 h group had a lower interleukin-12 P70 ( t=2.46, P<0.05) and interferon-γ levels ( t=2.55, P<0.05) than EN-initiated after 24 h group. Prior to discharge, the EN-initiated within 24 h group has a lower mean skinfold thickness ( t=2.49, P<0.05) and lower mid-upper arm circumference ( t=2.36, P<0.05) compared with the EN-initiated after 24 h group. Conclusions:Initiating EN within 24 h postoperatively is safe and feasible in pediatric heart transplant recipients. Early EN may shorten the length of intensive care unit stay and mechanical ventilation while attenuating postoperative release of inflammatory cytokine.
