Objective Based on the structure-activity relationships on the reported antifungal agents bearing quinoline or thiophene moieties ,novel compounds bearing both quinoline and thiophene were designed ,synthesized ,and evaluated for in vitro antifungal activity against Candida albicans .Methods With 5-cyanothiophene-2-carbaldehyde or 5-cyanothiophene-3-car-baldehyde as starting materials ,13 compounds were synthesized via reductive amination ,reduction of cyano group and amida-tion of quinoline-or isoquinoline-carboxylic acid .Their chemical structures were characterized by 1 H NMR and MS . In vitro antifungal screening against Candida albicans SC5314 was performed with the microbroth dilution method .Results All the compounds exhibited potent antifungal activities against Candida albicans .Among them ,compound 6k showed the highest an-tifungal activity with MIC80 value of 0 .5 μg/ml ,which is same potent as fluconazole .Conclusion The designed compounds bearing both quinoline and thiophene exhibited potent antifungal activities ,and deserve further research .

Sinusitis is a prevalent nasal disease in children, characterized by chronic and difficult-to-treat symptoms. Its onset is related to nasal stagnation, gallbladder and lung dysfunctions. This article explores the root cause based on Huangdi Neijing by considering the physiological and pathological characteristics of children. The core pathogenesis of pediatric sinusitis is the transmission of heat from the gallbladder and lung to the brain and nose, disrupting normal nasal function. Wind and heat pathogens often persist, accumulate, and transform into turbid qi, which are common triggers of the disease. Evil qi retention and yin depletion are internal factors that cause the prolonged and unhealed condition of the disease. This article emphasizes individualized treatment approaches based on disease duration and the severity of pathogenic factors. If external pathogens remain uncleared, treatment should focus on dispelling wind, clearing heat, dispersing with pungent medicinals, and dredging nasal orifices. If internal fire is exuberant, clearing lung qi, inhibiting hyperactive liver yang, and clearing exuberant fire should be used to relieve stagnation. In chronic cases with residual pathogens and liver-kidney yin deficiency, nourishing yin, clearing fire, and moistening the nasal orifices are essential. When exuberant heat has subsided, but the symptom of a persistent runny nose continues, leading to the loss of healthy qi and damage to the lung and spleen, treatments that tonify the spleen, benefit the lung, and reinforce healthy qi should be adopted to relieve stagnation. These treatments aim to restore the balance of the body′s vital qi by addressing both the lingering symptoms and the underlying weakness of the lung and spleen. The diagnosis and treatment of pediatric sinusitis based on the theory of "the transmission of heat from gallbladder and lung" can help reduce the recurrence of sinusitis and alleviate symptoms, with the aim of broadening the approach of traditional Chinese medicine in treating this condition.

The main pathogenesis of chronic cough in children is the disorder of ascending and descending of qi movement caused by healthy qi deficiency and pathogenic qi retention. The deficiency of lung, spleen, and kidney is the root of the disease, and the retention of phlegm-fluid, food accumulation, and fire from constraint is the branch pathogenesis of the disease. In the treatment, we should reinforce and tonify healthy qi, dispel pathogen and regulate qi, with Yupingfeng Powder (玉屏风散) as the basic prescription. For lung qi deficiency syndrome, modified Yupingfeng Powder could be used for supplementing lung to consolidate the exterior; for lung and spleen qi deficiency syndrome, modified Yupingfeng Powder plus Shenling Baizhu Powder (参苓白术散) could be used for supplementing lung and fortifying the spleen, treating with both supplementation and transformation; for lung kidney qi deficiency syndrome, modified Yupingfeng Powder combined with Suzi Jiangqi Decoction (苏子降气汤) could be used for supplementing lung and replenishing kidneys, absorbing qi to the root. All the above prescriptions could combine the method of dispelling phlegm, promoting digestion and guiding out food stagnation, soothing the liver and draining fire to remove the solid pathogens, in order to treat the root and branch simultaneously, and the cough will stop if the ascending and descending of qi movement recover as usual.
