The incidence of pediatric adenoid hypertrophy increases year by year. However, the treatment methods are limited. By now TCM treatment has showed significant clinical efficacy in treating pediatric adenoid hypertrophy. And phlegm could be one of the main pathogenic factors. By collecting relevant literature about TCM treatment for pediatric adenoid hypertrophy, this article summarized the thoughts of treating from phlegm based on the collection and analysis of classification of syndrome and treatment methods guided by the thoughts of treating from phlegm.

Objective To evaluate the effects of inhaled iloprost on pulmonary hypertension after cardiopulmonary bypass in patients with congenital heart disease undergoing surgical correction of anomaly. Methods Fifty-eight patients with congenital heart disease aged 14-60 yr undergoing surgical correction of anomaly under cardiopulmonary bypass (CPB) were enrolled in this study. Radial artery was cannulated before induction of anesthesia. A 6-lumen pulmonary catheter was placed via right internal jugular vein after tracheal intubation. Their mean pulmonary arterial pressure was still > 25 mm Hg after operation. ECG, HR, BP, CO, PAP and SpO_2 were continuously monitored. Aerosolized iloprost 10 fig was inhaled via nebulizer after CPB. Hemodynamics were measured before iloprost inhalation (baseline) and at 0, 5, 15, 30 and 60 min after the end of iloprost inhalation. Results There were 28 patients with pulmonary hypertension after CPB among the 58 patients with congenital heart disease. Inhalation of iloprost 10μg significantly decreased mPAP, pulmonary vascular resistance and intrapulmonary shunt as compared with the baseline. Iloprost inhalation could also improve significantly CO and the mixed venous oxygen saturation (SvO_2 ). Conclusion Iloprost inhaled after CPB can effectively reduce pulmonary arterial pressure and pulmonary vascular resistance in patients with congenital heart disease undergoing surgical correction of anomaly and help them wean from CPB.

Objective To analyze the characteristics of TCM syndromes of children abnormal sweating;To investigate the correlation between diseases and primary and secondary syndromes. Methods Through a multi-center epidemiology investigation, 400 cases were collected to statistically analyze the five TCM syndromes of children abnormal sweating, and characteristics of each syndrome were analyzed. Results In the 400 cases of children abnormal sweating, there were 129 cases (32.25%) of dysfunction of lung-wei pattern, 50 cases (12.50%) of nutrient qi and defensive qi discordance, 84 cases (21.00%) of qi and yin deficiency pattern, 57 cases (14.25%) of dampness heat forced steamed pattern, and 80 cases (20.00%) of qi and yang deficiency pattern. Spontaneous sweating and night sweating were found in the four patterns besides qi and yin deficiency pattern, and night sweating can be mainly found in qi and yin deficiency. Each type is consistent in the syndrome differentiation and cluster analysis. Conclusion Spontaneous sweating and night sweating, each has the certification of yin and yang. Spontaneous sweating can be caused by yin deficiency while night sweating can be caused by yang deficiency. Each pattern of children abnormal sweating has its own syndrome characteristic, which can provide the basis for clinical diagnosis and treatment.

Objective: To investigate the characteristics of attentional bias in emotional faces of policemen with different trait anxiety levels. Methods: By using the State-Trait Anxiety Inventory (STAI), 44 policemen (23 males and 21 females) were included in the higher trait anxiety level group and 44 policemen (25 males and 19 females) were included in the lower trait anxiety level group. The 2 anxiety style ((higher trait anxiety level, lower trait anxiety level) × 2 emotional type (positive, negative) × 2 clue type (identical side, opposite side) hybrid design was used to investigate the attentional bias of the response time differences between the two groups of policemen on keystroke responses of different emotional types and different types of clues by using a dot probe. Results: The positive emotional face reaction of the higher trait anxiety level group was less than that of the negative emotional face reaction[ (638. 0 ± 12. 4) ms vs. (651. 7 ± 13. 1) ms, P ＜ 0. 01], while the lower trait anxiety level police had no statistical significance on the reaction of positive emotional face and negative emotional face (P＞ 0. 05). The clue types in the higher trait anxiety level group were identical side less than opposite side response time [ (640. 3 ± 12. 6) ms vs. (649. 5 ± 13. 0) ms, P ＜ 0. 05], and there was no statistical significance in the lower trait anxiety level group about identical side and opposite side response time (P＞ 0. 05). The clue type in identical side, there was no significant difference in the response of two groups to positive emotional faces and negative emotional faces (P＞ 0. 05); while the clue type in opposite side, the response of higher trait anxiety level group to negative emotional faces was higher than that of positive emotional faces [ (663. 1 ± 9. 8) ms vs. (651. 4 ± 8. 9) ms, P ＜ 0. 05]. Conclusion: It suggests that the policemen with higher level of trait anxiety have selective attentional bias to negative emotional faces, which induced by impaired attentional disengagement.

OBJECTIVETo observe autophagy induced by starvation in non-small cell lung cancer A459 and 95D cells.

METHODSA549 and 95D cells in logarithmic growth in 1640 medium were cultured in Earle's balanced salt solution (EBSS) for 0, 1, 2, 3, 4 or 5 h. Autophagosome formation in the cell culture was observed by MDC fluorescent staining, and the expression of microtubule-associated protein 1 light chain 3 (LC3) and Beclin1 in the cells were detected using Western blotting.

RESULTSCompared with the control cells, the cells with prolonged starvation showed increased MDC-positive cells and autophagosome formation. The expression of Beclin-1 and the LC3-II/LC3-I ratio also increased as the starvation prolonged, reaching the peak levels at 3 h and 4 h, respectively.

CONCLUSIONAutophagy can be induced by starvation in A549 and 95D cells in correlation with the expression of autophagy-related proteins LC3 and Beclin-1. These cell models of nutritional deficiency-induced autophagy may allow for a better understanding of the role of autophagy in the development of non-small cell lung cancer.

To identify novel inhibitors targeting the polo-box domain of polo-like kinase 1 (Plk1 PBD), a series of new peptidomimetics (7a-7u) without phosphate group were designed and synthesized, where the phosphate group in the structure of the selective Plk1 PBD inhibitor PLHSpT was replaced by the carboxyl group, and the unnatural amino acids were applied for further modification and optimization. The 21 peptidomimetic compounds designed and synthesized had a strong inhibitory effect on Plk1 PBD, of which compound 7l highly selectively inhibited Plk1 PBD with IC50 of 0.285 μmol/L. The growth inhibition effect of HeLa tumor cell lines in vitro was better than that of compounds containing phosphate group. Moreover, the stability of the compound in rat plasma was improved by unnatural amino acids. Thus it is proved that selective Plk1 PBD inhibitor with improved characters can be obtained by replacing the phosphate group with a carboxyl group and restructuring the peptide chain.
