OBJECTIVE: To investigate the therapeutic effect of nasal continuous positive airways pressure (nCPAP) combined with antireflux medicine on obstructive sleep apnea hypopnea syndrome (OSAHS) with gastroesophageal reflux (GER). METHOD: Sixty patients with moderate to severe OSAHS with GER were simultaneously received PSG and esophageal pH monitoring and randomly divided into control group and treatment group with each group 30 patients. The control group were simply received nCPAP for every night. The treatment group were received the same treatment and combined antireflux medicine, with esomeprazole 40 mg/d and mosapride citrate 5 mg, 3 times a day,oral. Both the groups symptomatic status of OSAHS and GER were observed on the third day and the 14th day during therapy, and then the same tests above were repeated on the 14th day. RESULT: Compared with the control group, the symptomatic improvement rate of OSAHS on the third day and 14th day during therapy,the symptomatic improvement rate of GER on the third day during therapy were increased with statistical significance in the treatment group (P<0.05), however, the difference of symptomatic improvement rate of GER between the two groups on the 14th day during therapy did not have statistical significance (P>0.05). Compared with those of the control group on the 14th therapeutic night, AHI, LSaO2, the percentage of time with pH<4, the longest reflux duration,reflux episodes and DeMeester scoring did not have statistical significance in the treatment group (P>0.05). CONCLUSION nCPAP is the most effective method for patients suffering OSAHS associated with GER, but nCPAP used in conjunction with anti-reflux drugs do not improve efficacy.

Combining with the currently applied psychology teaching mode of medical colleges and universities, regarding the core curriculum, abnormal psychology, as the object, we have explored the new teaching mode of graduate students majoring in applied psychology based on massive open online courses (MOOC), and promoted the fusion of classroom theory teaching, hospital practice, and MOOC course, so as to guide teaching reform of applied psychology and improve the quality of personnel training.

Phytoremediation plays an important role in the treatment of heavy metal pollution in soil. In order to elucidate the mechanism of salicylic acid (SA) on copper absorption, seedlings from Xuzhou (with strong Cu-tolerance) and Weifang Helianthus tuberosus cultivars (with weak Cu-tolerance) were selected for pot culture experiments. 1 mmol/L SA was sprayed upon 300 mg/kg soil copper stress, and the photosynthesis, leaf antioxidant system, several essential mineral nutrients and the changes of root upon copper stress were analyzed to explore the mechanism of copper resistance. The results showed that Pn, Tr, Gs and Ci upon copper stress decreased significantly compared to the control group. Meanwhile, chlorophyll a, chlorophyll b and carotenoid decreased with significant increase in initial fluorescence (F₀), maximum photochemical quantum yield of PSⅡ (Fv/Fm), electron transfer rate (ETR) and photochemical quenching coefficient (qP) content all decreased. The ascorbic acid (AsA) content was decreased, the glutathione (GSH) value was increased, the superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) activity in the leaves were decreased, and the peroxidase (POD) activity was significantly increased. SA increased the Cu content in the ground and root system, and weakened the nutrient uptake capacity of K, Ca, Mg, and Zn in the root stem and leaves. Spray of exogenous SA can maintain the opening of leaf stomata, improve the adverse effect of copper on photosynthetic pigment and PSⅡ reaction center. Mediating the SOD and APX activity started the AsA-GSH cycle process, effectively regulated the antioxidant enzyme system in chrysanthemum taro, significantly reduced the copper content of all parts of the plant, and improved the ion exchange capacity in the body. External SA increased the content of the negative electric group on the root by changing the proportion of components in the root, promoted the absorption of mineral nutrient elements and the accumulation of osmoregulatory substances, strengthened the fixation effect of the root on metal copper, and avoided its massive accumulation in the H. tuberosus body, so as to alleviate the inhibitory effect of copper on plant growth. The study revealed the physiological regulation of SA upon copper stress, and provided a theoretical basis for planting H. tuberosus to repair soil copper pollution.
