Objective To investigate the similarity and difference in chronic obstructive pulmonary disease ( COPD) evaluation and drug selection that were compared between global initiative for chronic ob-structive lung disease (GOLD) 2011 and GOLD 2006, and to explore treatment adherence by doctors ac-cording to GOLD 2011.M ethods We collected 224 patients with COPD from Department of Respiratory Medicine at the Second Xiangya Hospital to investigate the differences in COPD evaluation and drug selec-tion according to GOLD 2011 and GOLD 2006 with treatment adherence by doctors according to GOLD 2011.Results ⑴According to GOLD 2006, there were 38 patients in the most severe stage, which was different from that (Group D, 147) according to GOLD 2011 ( P <0.01).⑵The risk stratification by u-sing pulmonary function assessment was significantly different from that by using exacerbation history.⑶Symptom assessment by using COPD assessment test ( CAT) was significantly different from that by using modified British medical research council ( mMRC) .The kappa coefficient of these two questionnaires was 0.466, suggesting moderate agreement.⑷ According to GOLD 2011, 224 (100%) patients were recom-mended to use inhaled long-acting bronchodilators, which was higher than that (213, 95.18%) according to GOLD2006 ( P <0.01).⑸The level of appropriated actual prescription was 161 (71.9%) according to GOLD 2011, which was significantly different from that (120,53.1%) according to GOLD 2006 ( P <0.01).Conclusions ⑴ Compared to GOLD 2006, GOLD 2011 categorized more patients into the most severe group.⑵The risk stratification of COPD by airflow limitation severity or exacerbation risk was not i-dentical.Discordance between CAT and mMRC was observed.⑶GOLD 2011 recommends a wider range of using long-acting bronchodilators.⑷The adherence to GOLD guideline in our hospital is still far from satis-faction.

Objective To investiGate the value of procalcitonin( PCT ),C reactive protein( CRP ), white blood cell( WBC)and platelet in the diaGnosis of neonatal infection. Methods The clinical data of 57 cases with neonatal infection in the First Hospital of Hefei were retrospectively analyzed. Select 65 healthy neonates in the same period as control Group. Compared two Groups of serum PCT,CRP,WBC and platelet levels, and diaGnosed of sensitivity,specificity of neonatal infection. Results There were statistical siGnificant differences between infection Group and control Group interms of CRP,WBC and PCT in newborn health neonates ( P<0. 05),but except the platelet( P>0. 05). The sensitivity and specificity of PCT were 54. 4% and 92. 3%, of CRP were 43. 9% and 84. 6%,of WBC was 29. 8% and 90. 8%,and of PLT were 38. 6% and 69. 2%. Conclusion PCT,CRP,WBC are of diaGnostic siGnificance for early diaGnosis of neonatal infection,and PCT has hiGh sensitivity and specificity of diaGnosis of neonatal infectious diseases.

Objective: To study the effect of Xiaoyao Pills (containing Paeoniae Alba Radix) on peripheral blood and hypothalamic- pituitary-adrenocortical (HPA) axis in rats with syndrome of stagnation of liver qi and blood deficiency. Methods: The model of syndrome of stagnation of liver qi and blood deficiency was established by chronic restraint stress combined with radiation, and healthy male rats were randomly divided into four groups such as normal group, model group, Paeoniae Alba Radix group, and Xiaoyao Pills group. The rats in treatment groups and normal group were fed with medicines and pure water from day 1 of the experiment, respectively. The weight, peripheral blood, glucose consumption, and hypothalamic-pituitary-adrenal axis were measured. Results: Compared with the model group, the weight and amount of WBC of model group were decreased significantly (P < 0.001), and the amounts of ACTH, CORT, and CRH were increased significantly (P < 0.01 or 0.001). Glucose consumption test showed that the ability of model group to explore the novel environment was reduced (P < 0.01), Xiaoyao Pills group on the above indicators had a corresponding regulatory role (P < 0.001 or P < 0.01). Conclusion: The effect of Xiaoyao Pill on peripheral blood and HPA axis may be one of the mechanisms of its function of soothing liver to resolve depression and nourishing blood to invigorate the spleen.

Objective: To investigate the nourishing blood and smoothing liver effects of Paeoniae Radix Alba (PRA) based on metabolomics information. Methods: The stagnation of liver qi and blood deficiency syndrome rats model was established by chronic restraint stress combined with radiation. Using LC/MS method as the core technology, the principal component analysis (PCA) and partial least squares discriminate analysis (PLS-DA) as the main data analysis methods, endogenous metabolites were screened in the model rats to study the intervention mechanism of PRA. Results: Through the impact of phosphatidylcholine, lysophosphatidylcholine, ceramide, deoxycytidine, betaine, and other 21 kinds of small molecular metabolites, PRA had a certain callback effect on the disturbance of metabolic trajectory, which can improve the state of stagnation of liver qi and blood deficiency induced by external stimulating factors (such as irradiation, restraint, and loneliness). Conclusion: The nourishing blood and smoothing liver effects of PRA may be related to the sphingolipid metabolism, glycerophospholipid metabolism, linoleic acid metabolism, and alpha-linolenic acid metabolism.

It is important to explore the fundamental medical concepts which can enhance the overall quality of medical students in the department of geriatrics during clinical practice. These funda-mental medical concepts include medical humanistic spirit,holistic medicine,health management and patient-physician communication. Specific measures include improving emotional communication of clini-cal interns in department of geriatrics with elderly patients,training student's thinking as a whole towards multiple system disease in the elderly,training students to assess and manage elderly patients from a vari-ety of perspectives and improving doctor-patient communication skills by routine clinical teaching and teaching ward round. All these concepts will help improve the working ability and medical ethics of clini-cal interns and enable them to adapt to the clinical work quickly. So they can become qualified doctors.
