Mechanism of Qingfei Huatan Zhuyu Decoction in Treatment of COPD Based on "Lung and Intestinal Co-treatment" / 中国实验方剂学杂志

ObjectiveTo observe the effect of Qingfei Huatan Zhuyu decoction on the lung and intestinal function of rats with chronic obstructive pulmonary diseases （COPD） and explore the deep-seated mechanism of its embodiment of lung and intestinal co-treatment. MethodA total of 60 Wistar rats were randomly divided into six groups， with 10 rats in each group， and the groups were control group， model group， acute syrup group （10 g·kg-1·d-1）， and low， medium， and high-dose groups （10， 15， 20 g·kg-1·d-1） of Qingfei Huatan Zhuyu decoction. The COPD rat model was established by lipopolysaccharide tracheal drip combined with the smoke inhalation method， and the acute syrup group and the Qingfei Huatan Zhuyu decoction group were administered by gavage with corresponding dose concentrations respectively， while the rest groups were controlled by saline gavage， and the lung function and blood gas indexes of rats were monitored after the last administration. The histopathological changes in the lung and intestine were observed microscopically. The expression of serum interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， and secretory immunoglobulin A （IgA） in colon tissue were measured by enzyme-linked immunosorbent assay （ELISA）. The biochemical indexes such as serum diamine oxidase （DAO）， D-lactic acid， and malondialdehyde （MDA） were measured. Immunohistochemistry was used to detect the expression of tight junction protein （Occludin） in rat colon tissue. The expression of F4/80 positive alveolar macrophages in rat lung tissue， and the expression of α-actin （α-SMA） and colonic atresia small band protein-1 （ZO-1） were determined by immunofluorescence. The protein expression of p-NF-κB p65， NF-κB p65， p-p38 MAPK， and p-p38 MAPK and the expression of Occludin and ZO-1 in colon tissue were detected in rat lung tissue by Western blot. ResultCompared with the normal group， the model group had pulmonary dysfunction， reduced forced vital capacity （FVC）， arterial partial oxygen pressure （PaO2）， arterial oxygen saturation （SaO2）， and dynamic lung compliance （Cdyn） （P<0.01）， and the pathological changes in the lung and intestine were obvious. The expressions of IL-6， TNF-α， DAO， D-lactic acid， and MDA in serum were increased （P<0.05，P<0.01）， and the protein expression ratio of p-NF-κB p65/NF-κB p65 and p-p38 MAPK/p38 MAPK in lung tissue was increased. The expression of F4/80 positive macrophages in lung tissue was enhanced. The expression of IgA， Occludin， and ZO-1 in colon tissue decreased （P<0.05，P<0.01）. Compared with the model group， the pulmonary function of the rats in the acute syrup group and groups of Qingfei Huatan Zhuyu decoction was significantly improved， and the FVC， PaO2， SaO2， and Cdyn were increased （P<0.05， P<0.01）. The pathological changes in the lung and intestine were significant. The expressions of IL-6， TNF-α， DAO， D-lactic acid， and MDA in serum were decreased （P<0.05，P<0.01）， and the expressions of F4/80 positive macrophages in lung tissue were decreased （P<0.01）. The protein expression ratio of p-NF-κB p65/NF-κB p65 and p-p38 MAPK/p38 MAPK in lung tissue decreased （P<0.01）， and the expression of IgA， Occludin， and ZO-1 in colon tissue increased （P<0.01）. ConclusionQingfei Huatan Zhuyu decoction can effectively reduce the symptoms of COPD rats， and its mechanism of action is related to inhibiting the inflammatory response of lung tissue and improving the barrier function of the intestinal mucosa.

Relationship between BRAF V600E, TERT promoter mutations and the clinicopathological features of papillary thyroid carcinoma / 中国肿瘤临床

Objective: To explore the relationship between TERT promoter mutations and BRAF V600E as well as their coexistence with the clinicopathological features of papillary thyroid cancer (PTC). Methods: A total of 728 patients enrolled in Shanxi Cancer Hospital from December 2014 to December 2016 with PTC were retrospectively analyzed. We reviewed and analyzed the clinical results, pathology records, ultrasound results, and BRAF V600E and TERT status. Results: BRAF V600E mutations were found in 42.3% (308 of 728) of patients, and TERT C228T and C250T promoter mutations were found in 10.7% (78 of 728) and 0.5% (4 of 728) of patients, respectively. The TERT promoter mutation was significantly associated with old age (P=0.034), extrathyroidal invasion (P=0.026), large tumor size (P=0.028), cervical lymph node metastasis (P=0.012), distant metastasis (P=0.001), advanced disease stages (P<0.001), histological type (P=0.003) and recurrence (P=0.002). The BRAF V600E mutation was significantly associated with extrathyroidal invasion (P= 0.001), large tumor size (P<0.001), Hashimoto thyroiditis (P<0.001), distant metastasis (P=0.010), advanced disease stages (P=0.009) and recurrence (P=0.001). The coexistence of BRAF V600E and TERT promoter mutations was particularly associated with high-risk clinicopathological features, such as old age (P=0.024), extrathyroidal invasion (P=0.022), Hashimoto thyroiditis (P=0.005), the cervical lymph node (P=0.018), and advanced disease stages (P=0.002). Conclusions: Our study demonstrates that BRAF V600E and TERT promoter mutations play a significant role in the aggressiveness of PTC, particularly when the two mutations coexist. The results reveal the significant role of these mutations in the treatment and prognosis prediction of PTC.
