With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.

Objective: To explore the efficacy of focal radiofrequency ablation (RFA) in the treatment of low-to-intermediate risk localized prostate cancer and its impact on postoperative urinary control and sexual function recovery，in order to explore the feasibility of minimally invasive methods for the treatment of localized prostate cancer. Methods: Clinical data of 28 patients with low-to-intermediate risk localized prostate cancer who underwent RFA in Nanjing Drum Tower Hospital，Affiliated Hospital of Medical School during Jun.2017 and Feb.2021 were retrospectively analyzed.The 5-year failure-free survival (FFS) rate，surgery related complications，postoperative urinary control and sexual function were collected.The differences between the survival curves of patients in the low-risk and intermediate-risk subgroups were assessed with log-rank test and Breslow test. Results: All surgeries were successfully completed under local anesthesia.During the median follow-up of 43 (40-49) months，the 5-year FFS rate predicted by Kaplan-Meier method was 78.57%; 25 patients (89.29%) did not experience surgery-related complications; 27 patients (96.43%) were able to control urination; 1 patient developed new-onset sexual dysfunction.There was no significant difference in the survival curves between patients in the low-risk and intermediate-risk groups (P>0.05). Conclusion: RFA for patients with low-to-intermediate risk localized prostate cancer has good clinical efficacy，little impact on urinary control and sexual function recovery，and few postoperative complications，which can be used as one of the treatment options for these patients.

Continuous manufacturing, as an innovative pharmaceutical production model, offers advantages such as high production efficiency and ease of control compared to traditional batch production, aligning with the future trend of drug production moving toward greater efficiency and intelligence. However, the development of continuous manufacturing technology in wet granulation has been slow. On one hand, this is closely related to its high technical complexity, substantial equipment investment costs, and stringent process control requirements. On the other hand, the long-term use of the traditional batch production model has created strong path dependence, and the lack of mature standardized processes further increases the difficulty of technological transformation. To promote the deep integration of wet granulation technology with continuous manufacturing, this review systematically outlines the current application of wet granulation in continuous manufacturing. It focuses on the development of key technologies such as online detection, process modeling, and process scale-up, with the aim of providing a reference for process innovation and application in wet granulation.

This study aims to explore the impact of host plants on the quality of Taxilli Herba and provide a theoretical basis for the quality control of Taxilli Herba. The components of Taxilli Herba from three different host plants(Morus alba, Salix babylonica, and Cinnamomum cassia) and its 3 hosts(mulberry branch, willow branch, and cinnamon branch) were detected by widely targeted metabolomics based on ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS). Principal component analysis(PCA), orthogonal partial least squares discriminant analysis(OPLS-DA), and Venn diagram were employed for analysis. A total of 717 metabolites were detected in Taxilli Herba from the three host plants and the branches of these host plants by UPLC-MS/MS. The results of PCA and OPLS-DA of Taxilli Herba from the three different host plants showed an obvious separation trend due to the different effects of host plants. The Venn diagram showed that there were 32, 8, and 26 characteristic metabolites in samples of Taxilli Herba from M. alba host, S. babylonica host, and C. cassia host, respectively. It was found by comparing the characteristic metabolites of Taxilli Herba and its hosts that each host transmits its characteristic components to Taxilli Herba, so that the Taxilli Herba contains the characteristic components of the host. The Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis showed that the differential metabolites of Taxilli Herba from the three hosts were mainly enriched in flavonoid biosynthesis, arginine and proline metabolism, and glycolysis/gluconeogenesis pathways. Furthermore, the differential metabolites enriching pathways of Taxilli Herba from the three hosts were different depending on the host. In a word, host plants have a significant impact on the metabolites of Taxilli Herba, and it may be an important factor for the quality of Taxilli Herba.

The antidepressant activity and molecular mechanisms of Yueju Wan volatile oil were investigated. The Yueju Wan volatile oil was extracted by using supercritical CO_2. Gas chromatography-mass spectrometry(GC-MS) combined with network pharmacology identified 28 chemical constituents in Yueju Wan volatile oil, primarily terpenes and lactones. A total of 123 overlapping targets were associated with depression, including core targets of interleukin-1β(IL-1β), signal transducer and activator of transcription 3(STAT3), and caspase-3(CASP3). These targets were mainly involved in the prolactin, advanced glycation end products/receptor(AGE/RAGE), and phosphoinositide 3-kinase/protein kinase B(PI3K/Akt) signaling pathways. A reserpine-induced depression mouse model was established to evaluate the therapeutic effects and mechanisms of Yueju Wan volatile oil. The effects of Yueju Wan volatile oil on depression-like behavior in mice were evaluated by analyzing body mass, body temperature index, tail suspension immobility time, forced swimming immobility time, and sucrose preference. Hematoxylin-eosin(HE) staining revealed neuronal protection of Yueju Wan volatile oil in the brain of mice. Enzyme-linked immunosorbent assay(ELISA) and Western blot were employed to detect the protein expression of AGEs, IL-1β, phosphorylated PI3K(p-PI3K), Akt, phosphorylated Akt(p-Akt), nuclear factor κB(NF-κB), and brain-derived neurotrophic factor(BDNF). Behavioral evaluation showed that Yueju Wan volatile oil could effectively control the decline of body mass and body temperature of depressed mice, reduce tail suspension and swimming immobility time, and enhance their preference for sucrose. Histopathological examination showed that Yueju Wan volatile oil could alleviate the neuronal damage in CA1 and dentate gyrus(DG) of the hippocampus of mice. ELISA and Western blot results showed that Yueju Wan volatile oil could significantly increase the protein expression levels of PI3K, Akt, and BDNF and significantly decrease the protein expression levels of AGEs, IL-1β, p-PI3K, p-Akt, and NF-κB in the hippocampus of mice. Furthermore, the p-PI3K/PI3K and p-Akt/Akt ratios were significantly decreased at medium and high doses. These findings suggest that the aromatherapy of Yueju Wan volatile oil can significantly improve reserpine-induced depression-like behavior in mice, which may be related to reducing the expression of neuronal membrane protein AGEs, reducing the phosphorylation levels of PI3K and Akt, inhibiting NF-κB entry into the nucleus, and alleviating the release of pro-inflammatory factors and nerve injury.

OBJECTIVE: To investigate the clinical characteristics and prognosis of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). METHODS: Clinical data of 10 patients with PTCL-NOS in Gansu Provincial Hospital from May 2016 to June 2023 were collected. The treatment outcomes were evaluated, and the factors affecting prognosis were analyzed. RESULTS: The median age of onset for the 10 patients was 60.7 (47-75) years, with 7 males and 3 females. Nine cases received chemotherapy, while one case died suddenly after diagnosis, and the median course of chemotherapy was 6.9 (1-13) courses. Assessing the efficacy, 3 patients achieved complete remission (CR) while 7 patients showed progression. Age, sex, lactate dehydrogenase (LDH) level, Ki-67 and the presence of hemophagocytic lymphohistocytosis (HLH) were not statistically correlated with CR rate ( P >0.05). Patients with IPI score 3-5, and Ann Arbor stage III-IV had statistically lower CR rates (both P <0.05). Age, B symptoms, LDH level ,hemoglobin, Ki-67 index and PLR value were not statistically correlated with overall survival (OS) time ( P >0.05). Male, platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, presence of HLH, NLR≥4.05, and LMR <2.81 were statistically correlated with shorter OS (all P <0.05). Among the 10 patients, 3 cases have survived and are still in CR status, while 7 cases have died, with a median survival time of 7.5 (1-85) months. CONCLUSIONS Patients with IPI score 3-5 and Ann Arbor stage III-IV have low CR rate and poor prognosis. The OS of patients who are male, with platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, complication of HLH, NLR≥4.05, and LMR <2.81 is short, and prognosis is poor.

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with hemophagocytic lymphohistiocytosis (HLH). METHODS: Clinical data of 78 patients with HLH admitted to Gansu Provincial People's Hospital from January 2014 to May 2023 were collected, and the correlation between relevant indicators and patient prognosis was analyzed. RESULTS: Among the 78 HLH patients, there were 48 males and 30 females, with a median age of onset of 48 (1-84) years old; 26 patients were treated with chemotherapy, 44 patients were treated with glucocorticoids, immunoglobulin or cyclosporine, 5 patients received symptomatic treatment, 1 patient received plasma exchange, and 2 patients refused treatment. By the end of the follow-up, there were 39 survivors, 35 deaths, and 4 patients lost to follow-up. There was no significant correlation between sex, ferritin, triglycerides, hemophagocytosis, bone marrow cellularity, Epstein-Barr virus (EBV) infection, SUV value of PET-CT, alanine aminotransferase (ALT), interleukin-6 (IL-6), platelet-to-lymphocyte ratio (PLR) and overall survival (OS) of the patients (P >0.05). Patients with age≥60 years, neutrophil-to-lymphocyte ratio (NLR) >0.59, red cell distribution width-to-platelet ratio (RPR) >0.30, lymphocyte-to-monocyte ratio (LMR)≤2.74, red blood cell distribution width (RDW)>16.45%, tumor-associated HLH, aspartate aminotransferase (AST)≥148 U/L, procalcitonin (PCT)≥0.66 ng/ml, neutrophils (NEU) <2×10⁹/L, fibrinogen (FIB)<1.85 g/L, lactate dehydrogenase (LDH)≥1 740 U/L, hemoglobin (Hb)<85 g/L, platelet (PLT)<57×10⁹/L had significantly shorter OS, with statistical significance (P < 0.05). Multivariate analysis showed that LMR≤2.74, RDW>16.45%, LDH≥1 740 U/L, and NEU<2×10⁹/L were independent risk factors affecting OS in HLH patients (P < 0.05). CONCLUSION Some blood-based inflammatory markers are significantly associated with OS in patients with HLH. NLR, RPR, LMR, RDW and PCT can be used to assess the prognosis of HLH patients, and RDW and LMR are independent factors affecting OS of HLH patients, which provide greater predictive value for prognosis. Hypercellular bone marrow in HLH patients may indicate a poor prognosis.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

OBJECTIVE To investigate the effect of bs-5-YHEDA iron chelating peptide combined with semaglutide on the cognitive ability and pathological characteristics of D-Gal-induced Alzheimer's disease(AD) model mice. METHODS Forty mice were randomly divided into 5 groups, namely the healthy control group, PBS group, bs-5-YHEDA iron chelating peptide group, combined treatment group and positive control group, with 8 mice in each group, half of each sex. Except for the healthy control group, D-galactose was injected to induce the AD mice model for 6 weeks. For 3 consecutive weeks starting from the 4th week, the bs-5-YHEDA iron chelating peptide group was injected with bs-5-YHEDA(1 mg·mL–1) once every other day at 200 µL in the tail vein; the bs-5-YHEDA iron chelating peptide(1 mg·mL–1) and semaglutide(25 nmol·kg–1·d–1) were given alternately once a day in the combination treatment group; the positive control group was given memantine(3.3 mg·kg–1·d–1) by gavage every other day. The healthy control group and PBS group were injected with the equal dose of PBS. At the end of treatment, the learning memory ability of mice was detected by the Morris water maze method, whole brain and whole blood were dissected, and pathological changes in hippocampal region were observed by HE staining, and Aβ expression and Tau protein phosphorylation levels were detected by immunohistochemistry, enzyme-linked immunosorbent assay and immunoblotting. RESULTS In the Morris water maze spatial exploration experiment, the differences in the number of times the mice traversed the platform, the ratio of swimming distance to the target quadrant, and the time ratio were statistically significant in each group(P<0.05); compared with the PBS group, the ratio of swimming distance to the target quadrant increased in the combined treatment group, and the differences were statistically significant(P<0.05). The results of HE staining showed that compared with the healthy control mice, the hippocampal area in the PBS group showed reduced levels of pyramidal cells, disorganized arrangement, cell edema, and deep staining of nuclei consolidation. Cellular disorganization, deep staining of nuclei and apoptosis in the hippocampus were significantly improved in each treatment group after drug treatment. Immunohistochemistry and Western blotting results showed that the Aβ expression levels and Tau protein phosphorylation levels were significantly higher in the PBS-administered mice compared with the healthy control mice, and the Aβ expression levels and Tau protein phosphorylation levels were reduced in each group after drug treatment, with statistically significant differences(P<0.01 or P<0.001 ). CONCLUSION The combination of bs-5-YHEDA iron chelating peptide and semaglutide can effectively improve the learning and memory ability and pathological characteristics of AD mice, but from the results of immunohistochemistry and immunoblotting experiments, the improvement of pathological characteristics of AD mice in the combination treatment group is not obvious compared with the single bs-5-YHEDA iron chelating peptide group, suggesting that there may be a threshold effect of our designed dual-target combination treatment on the cognitive improvement of AD mice, and the optimization and validation of the effect of multi-target combination treatment need further study.
