Objective:The paper aims to provide recommendations for improving the essential medicines’ cen-tralized bidding procurement and quantity-based pricing policy. Methods: Based on the documents and literature on essential medicines’ centralized bidding procurement, we analyzed the factors which have a great impact on implemen-tation of the quantity-based pricing in essential medicines’ centralized procurement using the text research, semi-structured interview questionnaire and on-phone interviews. Results:The quantity-based pricing needs to define a ge-neric name and specific dosage form of drugs in the essential medicines’ centralized procurement. Its implementation was mainly influenced by the following factors:the procurement area accessibility, the pharmaceuticals category, dis-ease and drug alternative procurement methods and cycle, the payment and settlement time, and irregularities in the procurement process. Suggestions:During this implementation, we also need to clearly predict the quantity and pro-curement method, set up a proper policy environment for a quantity-based pricing, cancel the price linkage mecha-nism, strictly put into practice the payment deadline, employ a unique billing method and strengthen the information construction for the provincial centralized procurement platform. Some medicines’ quantity-based pricing should be carried out in the chosen pilots for laying a good foundation for its promotion.

Objective To compare the consistency between interstitial fluid glucose and arterial blood glucose in septic shock patients with different tissue perfusion levels.Methods A prospective investigative study was conducted. Sixty-one septic shock patients with ages above 18 years old admitted to the Department of Critical Care Medicine of Peking Union Medical College Hospital, Chinese Academy of Medical Sciences from April 2013 to December 2013 were enrolled. The real-time continuous glucose monitoring system (RTCGMS) and arterial blood gas analyzer were used to measure the patients' interstitial fluid glucose and arterial blood glucose, and according to the criteria of International Organization for Standardization (ISO) and the median of relative absolute difference (Median RAD), the consistency between interstitial fluid glucose and arterial blood glucose was calculated. Based on the lactate (Lac) level and pulse oxygen perfusion index (PI), the septic shock patients were divided into groups with different degrees of tissue perfusion, the consistency between the interstitial fluid glucose and arterial blood glucose among septic shock patients with different degrees of tissue perfusion was compared by using Bootstrap re-sampling technique.Results Negative correlation existed between PI and Lac (r= -0.272,P < 0.001), which showed the opposite change tendency of organism tissue perfusion. In patients with Lac > 8 mmol/L, their consistency between interstitial fluid glucose and arterial blood glucose was better than that in those with Lac > 2-4 mmol/L, and the 95% credibility intervals (CI) of ISO standardized deviation value was 0.026-38.710 (P < 0.05). In patients with PI ≤ 0.7%, their consistency between interstitial fluid glucose and arterial blood glucose was better than that in those with PI > 0.7%-1.4%, the 95%CI of median RAD difference value was 0.002-0.076, and the 95%CI of ISO standardized deviation value was -27.000 to -0.583 (allP < 0.05); in patients with PI > 3.0%, their consistency between interstitial fluid glucose and arterial glucose was better than that in those with PI ≤ 0.7%, PI > 0.7%-1.4% and PI > 1.4%-3.0%, and the 95%CI of ISO standardized deviation values were 3.322-28.302, 11.988-40.265 and 5.170-33.333 respectively (allP < 0.05).Conclusions When septic shock patients were under low tissue perfusion (Lac > 8 mmol/L or PI ≤ 0.7%), the worse the tissue perfusion, the better the consistency between interstitial fluid glucose and arterial blood glucose; when septic shock patients were under normal local tissue perfusion (PI > 3.0%), the better the local tissue perfusion, the better the consistency between interstitial fluid glucose and arterial blood glucose.

Chinese Journal of School Health 2020;41(6):859-862
Objective:
To explore the intervention effect of health education combined with aerobic exercise on adolescent depression,and to provide a reference for depression prevention of adolescents.
Methods:
A total of 84 adolescent patients with depression in Wuhan Mental Health Center were selected by convenient sampling method. They were divided into two groups according to the order of patients visits (n=42). The control group received routine health education. The experimental group received group health education of emotional intelligence, and cooperated with moderate intensity aerobic exercise. The changes of depression, emotional intelligence and serotonin (5-HT), cortisol and norepinephrine (NE) levels before and after intervention were compared between the two groups.
Results:
Before intervention, there was no significant difference in scores of Hamilton Depression Scale (HAMD) and Social Disability Screening Schedule (SDSS) between the two groups (t=0.62,1.02,P>0.05). The scores of HAMD and SDSS in the experimental group were significantly lower than those before intervention (t=9.62, 10.05, P<0.05). The scores of HAMD and SDSS in the experimental group were significantly lower than those in the control group (t=-6.95,-7.32,P<0.05). The scores and total scores of emotional perception, self-management and other management in the experimental group after intervention were significantly higher than those before intervention (t=6.54, 7.21, 5.33 ,6.60, P<0.05). The scores of emotion perception, self-management, others’ management and total scores in the experimental group were significantly higher than those in the control group(P<0.05). compared with before intervention, the levels of 5-HT and NE in the experimental group after intervention were significantly higher, the levels of cortisol were significantly lower (t=4.62, 5.36,-16.54, P<0.05),and the level of 5-HT and NE in the experimental group was significantly higher than that in the control group, and the level of cortisol was significantly lower than that in the control group (t=15.25,8.74,-26.54,P<0.05).
Conclusion
The implementation of emotional intelligence group health education and aerobic exercise can effectively reduce the level of 5-HT, improve the level of cortisol, enhance the emotional intelligence of adolescents with depression, and alleviate their depressive mood.
