Sepsis-induced liver injury (SILI) is an important cause of septicemia deaths. BaWeiBaiDuSan (BWBDS) was extracted from a formula of Panax ginseng C. A. Meyer, Lilium brownie F. E. Brown ex Miellez var. viridulum Baker, Polygonatum sibiricum Delar. ex Redoute, Lonicera japonica Thunb., Hippophae rhamnoides Linn., Amygdalus Communis Vas, Platycodon grandiflorus (Jacq.) A. DC., and Cortex Phelloderdri. Herein, we investigated whether the BWBDS treatment could reverse SILI by the mechanism of modulating gut microbiota. BWBDS protected mice against SILI, which was associated with promoting macrophage anti-inflammatory activity and enhancing intestinal integrity. BWBDS selectively promoted the growth of Lactobacillus johnsonii (L. johnsonii) in cecal ligation and puncture treated mice. Fecal microbiota transplantation treatment indicated that gut bacteria correlated with sepsis and was required for BWBDS anti-sepsis effects. Notably, L. johnsonii significantly reduced SILI by promoting macrophage anti-inflammatory activity, increasing interleukin-10+ M2 macrophage production and enhancing intestinal integrity. Furthermore, heat inactivation L. johnsonii (HI-L. johnsonii) treatment promoted macrophage anti-inflammatory activity and alleviated SILI. Our findings revealed BWBDS and gut microbiota L. johnsonii as novel prebiotic and probiotic that may be used to treat SILI. The potential underlying mechanism was at least in part, via L. johnsonii-dependent immune regulation and interleukin-10+ M2 macrophage production.

BACKGROUND:
Idiopathic pulmonary fibrosis (IPF) is an idiopathic chronic, progressive interstitial lung disease with a diagnosed median survival of 3-5 years. IPF is associated with an increased risk of lung cancer. Therefore, exploring the shared pathogenic genes and molecular pathways between IPF and lung adenocarcinoma (LUAD) holds significant importance for the development of novel therapeutic approaches and personalized precision treatment strategies for IPF combined with lung cancer.
METHODS:
Bioinformatics analysis was conducted using publicly available gene expression datasets of IPF and LUAD from the Gene Expression Omnibus (GEO) database. Weighted gene co-expression network analysis was employed to identify common genes involved in the progression of both diseases, followed by functional enrichment analysis. Subsequently, additional datasets were used to pinpoint the core shared genes between the two diseases. The relationship between core shared genes and prognosis, as well as their expression patterns, clinical relevance, genetic characteristics, and immune-related functions in LUAD, were analyzed using The Cancer Genome Atlas (TCGA) database and single-cell RNA sequencing datasets. Finally, potential therapeutic drugs related to the identified genes were screened through drug databases.
RESULTS:
A total of 529 shared genes between IPF and LUAD were identified. Among them, SULF1 emerged as a core shared gene associated with poor prognosis. It exhibited significantly elevated expression levels in LUAD tissues, concomitant with high mutation rates, genomic heterogeneity, and an immunosuppressive microenvironment. Subsequent single-cell RNA-seq analysis revealed that the high expression of SULF1 primarily originated from tumor-associated fibroblasts. This study further demonstrated an association between SULF1 expression and tumor drug sensitivity, and it identified potential small-molecule drugs targeting SULF1 highly expressed fibroblasts.
CONCLUSIONS
This study identified a set of shared molecular pathways and core genes between IPF and LUAD. Notably, SULF1 may serve as a potential immune-related biomarker and therapeutic target for both diseases.

Cyclin-dependent kinase 9 (CDK9) activity is correlated with worse outcomes of triple-negative breast cancer (TNBC) patients. The heterodimer between CDK9 with cyclin T1 is essential for maintaining the active state of the kinase and targeting this protein-protein interaction (PPI) may offer promising avenues for selective CDK9 inhibition. Herein, we designed and generated a library of metal complexes bearing the 7-chloro-2-phenylquinoline CˆN ligand and tested their activity against the CDK9-cyclin T1 PPI. Complex 1 bound to CDK9 via an enthalpically-driven binding mode, leading to disruption of the CDK9-cyclin T1 interaction in vitro and in cellulo. Importantly, complex 1 showed promising anti-metastatic activity against TNBC allografts in mice and was comparably active compared to cisplatin. To our knowledge, 1 is the first CDK9-cyclin T1 PPI inhibitor with anti-metastatic activity against TNBC. Complex 1 could serve as a new platform for the future design of more efficacious kinase inhibitors against cancer, including TNBC.

With the allocation in funding for research, there has been growing interest in studying evidence-based policy formulation and decision-making to account for the funding allocation. By employing a narrative review, this paper focuses on the successes, failures, and challenges in the adoption of the MPOWER strategies in implementing the Tobacco Control Policy in Malaysia. The main objective of this paper is to narrate on the translations of research evidence in the design and implementation of the Tobacco Control Policy in Malaysia. Comparisons are made with developed and developing countries. Literature on tobacco control acts and policies were retrieved from online databases using keywords such as “smoking, tobacco, cigarette, and policy control”. Malaysia has adopted both local and global research evidence in implementing the Tobacco Control Policy and has seen steady progress in reduced prevalence of smoking through the years. Nevertheless, some challenges, including shortage of manpower for the enforcement and innovation of tobacco products, prevail, and more efforts are warranted.

Ovitrap surveillance was conducted to determine the infestation patterns of dengue
vectors in fourteen study sites across eight provinces located in the Sunda Islands, Indonesia.
High ovitrap indices up to 70% and 90% were obtained from indoor and outdoor areas,
respectively. Mean numbers of Ae. aegypti and Ae. albopictus larvae ranged from 0.13 to
14.50 and 0.10 to 18.60, respectively. Mixed infestation (<10%) and interchange of breeding
habitat preferences of Ae. albopictus and Ae. aegypti were also observed in the present study.

OBJECTIVETo investigate the prognostic significance of Follicular Lymphoma International Prognostic Index 2 (FLIPI2) in FL patients treated with rituximab maintenance.
METHODSA tatol of 140 newly diagnosed FL patients who received Rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) chemotherapy in our department were retrospectively analyzed from December 2002 to December 2014. Among 140 patients with FL 122 patients achieved response, from them 56 patients received R maintenance (RM) every 2 months for median 8 times (RM group) while the rest 66 patients did not receive further anti-lymphoma treatment (non-RM group).
RESULTSThere was no statistical difference in age, sex, pathologic grading, staging, FLIPI or FLIPI2 between RM and non-RM groups. The 2-year progression-free survival (PFS) of RM and non-RM groups were 89.7% and 77.6% (P=0.043) while the 2-year overall survival were 100% and 98.6% (P=0.131). FLIPI2 is a significant prognostic model either in the total cohort, RM or non-RM groups (P<0.001 all). In subgroup analysis, RM was able to decrease disease progression in low and intermediate-risk group of FLIPI2, while the 2-year PFS of RM and non-RM groups in high-risk group were similar (55.6% vs 46.9%)(P=0.920).
CONCLUSIONFLIPI2 presents robust prognostic significance either in RM or OBS patients, the patients in FLIPI2 low and intermediate-risk group may benefite from RM, but the role of RM in high-risk patients should be further to investigate.

Platelet-enriched plasma (PRP) contains high concentration of platelets and abundant growth factors, which is made by centrifuging of blood and separating of blood elements. PRP promotes tendon repair by releasing various cytokines to enhance cell proliferation, tenogenic differentiation, formation and secretion of matrix; meantime, it can reduce pain by inhibiting the expression of pain-associated molecules. A number of clinical studies demonstrated that PRP was effective in treatment of tendinopathy, including patellar tendinopathy, lateral epicondylitis and plantar fasciopathy. However, some studies did not support this conclusion, because of disparity of PRP types, therapeutic courses and injections protocols in clinical application. Based on its safety, PRP can be a choice of treatment for tendinopathy, in case other non-surgical therapies are of no effect.
