Objective To summarize the clinical experience of treatment of recurred urinary stone.Methods The patients who needed to be treated again from 1998 to 2002 were reviewed.Results Patients with recurred urinary stone were differentiated by symptom,the causation of recurred stone and operation.Conclusion The pointed step must be adopted based on the clinical character of recurred urinary stone.Preventing against recurred and choosing appropriate method can improve the treatment effect.

The symptoms of pulmonary nodules are insidious,with inflammatory nodules,inflammatory granuloma,early invasive cancer and lung cancer,and the clinical differential diagnosis is still difficult.Regular CT follow-up observation of most pulmonary nodules provides a"window period"for TCM Intervention in pulmonary nodules.From the aspects of external cold attacking the lung,dense cold and humid geographical environment,cold diet,summer air conditioning,etc.,this paper considers that the soaking of cold pathogenic factors is the basic cause of the formation of pulmonary nodules,and cold phlegm are the basic pathogenesis of pulmonary nodules.The clinical manifestations of cold phlegm in pulmonary nodules are summarized from the two actual situations that can be distinguished from clinical symptoms and no symptoms.It is proposed that Mahuang Fuzi Xixin Decoction and Sanzi Yangqin decoction are the basic formulas,Discussion on the treatment of pulmonary nodules by warming yang and dispelling cold to cure the root cause,eliminating phlegm and softening hard mass to treat the symptoms;Improve the ability of TCM diagnosis and treatment of pulmonary nodules.

N ⁶-methyladenosine (m⁶A) modification is critical for mRNA splicing, nuclear export, stability and translation. Fat mass and obesity-associated protein (FTO), the first identified m⁶A demethylase, is critical for cancer progression. Herein, we developed small-molecule inhibitors of FTO by virtual screening, structural optimization, and bioassay. As a result, two FTO inhibitors namely 18077 and 18097 were identified, which can selectively inhibit demethylase activity of FTO. Specifically, 18097 bound to the active site of FTO and then inhibited cell cycle process and migration of cancer cells. In addition, 18097 reprogrammed the epi-transcriptome of breast cancer cells, particularly for genes related to P53 pathway. 18097 increased the abundance of m⁶A modification of suppressor of cytokine signaling 1 (SOCS1) mRNA, which recruited IGF2BP1 to increase mRNA stability of SOCS1 and subsequently activated the P53 signaling pathway. Further, 18097 suppressed cellular lipogenesis via downregulation of peroxisome proliferator-activated receptor gamma (PPARγ), CCAAT/enhancer-binding protein alpha (C/EBPα), and C/EBPβ. Animal studies confirmed that 18097 can significantly suppress in vivo growth and lung colonization of breast cancer cells. Collectively, we identified that FTO can work as a potential drug target and the small-molecule inhibitor 18097 can serve as a potential agent against breast cancer.
