Drug therapy and surgical treatment are the two primary methods for treating renal tuberculosis.With the increase in drug-resistant strains,some novel anti-tuberculosis drugs,such as Delamanid and Bedaquiline,are being developed and gradually applied in clinical practice.Surgical treatment is suitable for patients with poor re-sponses to drug therapy and those who develop complications.Surgical methods include nephrectomy and partial nephrectomy.As the goal of preserving renal function as much as possible becomes more important,minimally in-vasive treatments have been adopted,with significant contributions from percutaneous nephrostomy and ureteral stent placement.Additionally,immunotherapy has emerged as a new direction,with immunomodulators such as interferons and interleukins under investigation.This article discusses the status and research progress in the treat-ment of renal tuberculosis,aiming to provide a theoretical basis for future treatments.

Objective:To investigate the role of reactive astrocytes expressing aromatase(ARO)in the penumbra during ischemic stroke.Methods:A mouse model of middle cerebral artery occlusion(MCAO/R)was prepared using the suture method.Western blot and immunofluorescence staining were used to observe the expression of ARO in the penumbra after ischemia reperfusion.We generated a glial fibrillary acidic protein promoter-driven aromatase knock-out(GFAP-ARO-KO)mouse model in vivo.Neurologic impairment scores,rotarod test,grip strength test and adhesive removal test on the plantar surface of the paw were performed after MCAO/R modeling.Results:In wild type mice,the expression of ARO was significantly increased in astrocytes in the penumbra after MCAO/R(P<0.01).Compared to the control group,the expression of ARO in the GFAP-ARO-KO group was significantly reduced in astrocytes in the penumbra after MCAO/R.And loss of ARO increased cerebral infarction volume and aggravated sensorimotor impair-ment.Conclusion:After ischemic stroke,reactive astrocytes in the penumbra highly express ARO and play a protective role in post-ischemia reperfusion injury.

Objective:To investigate the molecular mechanisms of bexarotene in treating double hit lymphoma(DHL)based on Weighted Gene Co-expression Network Analysis(WGCNA),thereby providing potential targets and experimental evidence for DHL treatment.Methods:The gene expression datasets GSE44164 and GSE43677 were downloaded from the Gene Expression Omnibus(GEO)database,and differentially expressed genes(DEGs)were identified.WGCNA was employed to identify gene modules associated with DHL.A protein-protein interaction(PPI)network was constructed to screen for key hub genes.Drug-gene association analysis was conducted using the EpiMed platform to identify potential targeted drugs for DHL.The effects of bexarotene on DHL cell proliferation and key protein expression were evaluated using the CCK-8 assay and Western blotting(WB),and its effects on cell apoptosis was evaluated using flow cytometry.Results:WGCNA identified a turquoise module highly associated with DHL,and 10 hub genes(COL1A2,COL3A1,MMP2,COL5A2,DCN,BGN,FN1,MMP9,FBN1,and LUM)were screened from the PPI network.Drug association analysis nominated bexarotene as a potential therapeutic agent.In vitro validation demonstrated that bexarotene significantly inhibited U2932 cell viability(P<0.05),promoted cell apoptosis(P<0.001),and downregulated c-Myc and COL1A2 expression(P<0.05).Conclusion:Bexarotene may exert anti-DHL effects by suppressing the c-Myc signaling pathway and modulating extracellular matrix-related genes.Further studies are warranted to validate its in vivo efficacy and potential for combination therapy.

Objective To study the clinical and CT findings of bronchiolar adenoma. Methods Patients diagnosed with bronchiolar adenoma confirmed by surgical pathology at Linyi People's Hospital and Yantai Yuhuangding Hospital from 2016 to 2021 were collected. Their clinical and CT imaging features were retrospectively analyzed. Results Finally, 25 patients were collected, including 6 males and 19 females, aged 32-73 (58.6±10.1) years. The immunohistochemical Ki-67 (MIB1) of all lesions was <5%. The lesions were located in the upper and middle lobe of both lungs in 9 patients, lower lobes in 16 patients, extrapulmonary zone in 22 patients, intrapulmonary middle zone in 3 patients, round in 11 patients, irregular in 14 patients, well-defined in 22 patients, pure ground-glass/mixed ground-glass nodules in 6 patients, solid nodules in 19 patients. There were 11 patients with central small cavity, 18 patients with single bronchioles sign, 19 patients without adhesion with adjacent pleura, and 24 patients without mediastinal lymph node enlargement. Conclusion Bronchiolar adenomas usually occur in the middle-aged and elderly, mostly in the lower lobe of both lungs and the distribution of the peripheral lung field, most of the patients do not have any clinical symptoms, and the postoperative prognosis is good. CT may show large nodules or masses, pure ground-glass/mixed ground-glass nodules, irregular solid nodules and central small cavities. Irregular stellate nodules, central small cavity shadow, and single bronchiolar vascular bundle connected with the lesions are relatively specific imaging findings of bronchiolar adenoma.

Microplastics(MPs)have attracted growing attention worldwide as an increasingly prevalent environmental pollutant.In addition,chicken meat is currently the most widely consumed kind of poultry in the global market.Consumer demand for chicken is on the rise both at home and abroad.As a result,the safety of chicken raising has also received significant attention.The lungs play an essential role in the physiological activities of chickens,and they are also the most vulnerable organs.Lung injury is difficult to repair after the accumulation of contaminants,and the mortality rate is high,which brings huge economic losses to farmers.The research on the toxicity of MPs has mainly focused on the marine ecosystem,while the mechanisms of toxicity and lung damage in chickens have been poorly studied.Thus,this study explored the effects of exposure to polystyrene microplastics(PS-MPs)at various concentrations for 42 d on chicken lungs.PS-MPs could cause lung pathologies and ultrastructural abnormalities,such as endoplasmic reticulum(ER)swelling,inflammatory cell infiltration,chromatin agglutination,and plasma membrane rupture.Simultaneously,PS-MPs increased the expression of genes related to the heat shock protein family(Hsp60,Hsp70,and Hsp90),ER stress signaling(activating transcription factor 6(ATF6),ATF4,protein kinase RNA-like ER kinase(PERK),and eukaryotic translation initiation factor 2 subunit α(eIF2α)),pyroptosis-related genes(NOD-,LRR-and pyrin domain-containing protein 3(NLRP3),apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),interleukin-1β(IL-1β),cysteinyl aspartate-specific proteinase 1(Caspase1),and gasdermin-D(GSDMD)),and the inflammatory signaling pathway(nuclear factor-κB(NF-κB),inducible nitric oxide synthase(iNOS),and cyclooxygenase-2(COX-2)).The above results showed that PS-MP exposure could result in lung stress,ER stress,pyroptosis,and inflammation in broilers.Our findings provide new scientific clues for further research on the mechanisms of physical health and toxicology regarding MPs.

Intestinal flora and bile acid metabolism regulate and influence each other,and an imbalance in the"intestinal flora-bile acid"pathway is closely related to atherosclerosis.Based on TCM theory and clinical practice,it is found that"earth congestion and wood depression"is the key mechanism of atherosclerosis,but its biological connotation needs to be further elucidated.Combined with the results of modern research,it is believed that intestinal flora imbalance is an important foundation of"earth congestion",and bile acid metabolism abnormality is an important manifestation of"wood depression".In the process of atherosclerosis,the imbalance of the"intestinal flora-bile acid"pathway is closely related to the"earth congestion and wood depression"pathogenesis of TCM in atherosclerosis.Exploring the biological connotation of the pathogenesis of"earth congestion and wood depression"of atherosclerosis from the"intestinal flora-bile acids"pathway is of far-reaching significance for clarifying the scientific connotation of TCM theory and guiding the TCM prevention and treatment of atherosclerosis.
