Objective To evaluate the clinical effect and safety of Huangzi Zhike granule for acute bronchitis with the syndrome of wind-cold attacking the lung.Methods A multi-center,randomized,double-blinded,double-simulation and positive drug parallel controlled trial was adopted.Three hundred and nine cases in the treatment group were treated with Huangzi Zhike granule,and 103 cases in the control group were treated with Tongxuan Lifei oral liquid.Results Huangzi Zhike granule had a total effective rate of 95.15 %and significantly relieved the symptoms of cough,spitting thin clear white sputum and throat itching.Compared with Tongxuan Lifei liquid,Huangzi Zhike granule showed a better clinical effect(P

Objective To investigate the regulatory effect of calcitonin gene-related peptide (CGRP) on the mRNA and protein expression of neuronal nitric oxide synthase (NOS), as well as the release of nitric oxide (NO) in cultured human keratinocyte line HaCaT. Methods NO level in the supernatant of cell culture medium was detected with an enzymatic NO detecting kit, the mRNA expression of neuronal NOS was studied with reverse transcription polymerase chain reaction(RT-PCR), and the protein expression of neuronal NOS was studied with immunochemical technique(SP). Results Compared with that in normal culture condition, the mRNA and protein expression of neuronal NOS and the release of NO was significantly upregulated by CGRP in HaCaT cells. Whereas, the expression of neuronal NOS and the release of NO in HaCaT cells induced by CGRP was inhibited by CGRP-8-37, an inhibitor of CGRP receptor. Conclusion The expression of neuronal NOS in keratinocytes and the release of NO from keratinocytes could be upregulated by CGRP.

This paper discussed the treatment of chronic cough of phlegm-dampness type based on the theory of “removing the earth stagnation”. It is believed that stagnation of qi in the middle energizer caused malfunction of water metabolism in the human body， which is the key pathogenetic mechanism leading to phlegm-dampness cough. Pathogenesis like cold and dampness attacking the spleen， dampness-heat obstruction， weakness of the middle energizer， failure to ascend clear yang， and internal blazing of yin fire may lead to “earth stagnation”， which triggered phlegm-dampness cough. The treatment advocated “removing the stagnation” to improve qi transformation in the middle energizer， eliminate stagnation， and use different treatment methods such as warming the middle， circulating qi， transforming phlegm and dampness based on different disease cause and mechanism to calm cough. As for prescriptions， Jiangling Banxia Decoction （姜苓半夏汤） could be used for cold-dampness syndrome， Banxia Xiexin Decoction （半夏泻心汤） plus Xiangsu Powder （香苏散） used for damp-heat syndrome， and Buzhong Yiqi Decoction （补中益气汤）， Tiaozhong Yiqi Decoction （调中益气汤）， Shengyang Yiwei Decoction （升阳益胃汤） and Bupiwei Xieyinhuo Shengyang Decoction （补脾胃泻阴火升阳汤） could be selected for spleen-stomach weakness syndrome according to different characteristics and pathogenesis.

Bronchiectasis is a refractory chronic airway disease characterized by chronic cough and phlegm production. Airway mucus hypersecretion is one of the important causative factors for acute exacerbation of bronchiectasis. Thus， reducing airway mucus secretion during the stable phase of bronchiectasis is the key to the treatment. Phlegm-dispelling therapy is commonly used in modern medicine， which， however， fails to radically reduce mucus secretion. At the moment， it is difficult and urgent to find an intervention that can improve the quality of life of patients and reduce the recurrence of disease during the stable phase of bronchiectasis. Chinese medicine shows remarkable efficacy in reducing airway mucus secretion. Nonetheless， there is a lack of research on the airway mucus hypersecretion of bronchiectasis， and no registered research outcome is available. Traditional Chinese medicine boasts a lot of experience in the treatment of phlegm. It combines clearing and tonifying methods and identifies Yin and Yang and internal organs， thus being advantageous in the treatment of airway mucus hypersecretion of bronchiectasis. Therefore， it is an important topic to improve the effectiveness of Chinese medicine on airway mucus hypersecretion of bronchiectasis by focusing on the "generation"， "transformation" and "excretion" of phlegm.

It is believed that the fundamental pathogenesis of the connective tissue diseases-associated interstitial lung disease （CTD-ILD） is kidney essence deficiency， with lung collateral obstruction throughout the disease， and environmental toxin pathogen is the important causative factors for the development of CTD-ILD. This article proposed to restore origin and alleviate bi （痹） for CTD-ILD， for which restoring origin means tonifying the lungs， spleen and kidneys to bank up the roots and consolidate the original qi， with modified Erxian Decoction （二仙汤） plus Liu Junzi Decoction （六君子汤）； alleviating bi means expelling wind and dredging collaterals， and eliminating the mass to restore the smoothness of the lung collaterals， with paired medicines of Chuanshanlong （Dioscorea nipponica）-Dilong （Kalanchoe pinnata）， Vinegar-processed Sanleng （Sparganium stoloniferum）-Vinegar-processed Ezhu （Curcuma zedoaria）， and stem-type medicines， and emphasized on removing the environmental toxin pathogens to facilitate the recovery of healthy qi.
