Objective To explore the event-related potentials (ERPs) P300 is changeable or not before and after treatment. Methods 99 cases of patients with first onset of depression diagnosed by DSM-Ⅳ as case group,and 100 cases matched with patients as control group were collected. P300 of two groups were obtained before and after treatment for 6 weeks,12 weeks,24 weeks. T test was used to analysis the difference of indicators of P300 among groups; repeated measure analysis of variance was used to analysis the longitudinal changes. Results shorter latency of N2-P3 ( (P ＜ 0.01 ); and lower amplitude of N2, P3, N2-P3 (P ＜ 0. 05 ), higher amplitude of P2-tency and a upward one in N2-P3 latency in the four periods; a upward trend could also be found in P3, N2-P3 amplitude, but there were no statistical differences(P ＞ 0. 05 ). The results of paired-samples t test: P3, N2-P3 amplitude in case group were higher after treatment for 6 weeks than before, the difference was significant (P ＜ 0.01 ); no significant results were found in P300 latency or amplitude between the 62 cases of depression after treatment for 24 weeks and the 65 normal controls selected (P ＞ 0. 05 ). Conclusion P300 latencies and amplitudes tend to be partly recovered after the acute treatment in patients with depression, but after the long-term therapy not clear.

[Objective]To explore SUN Congtian,a bibliophile,library scientist and proofreader in the Qing Dynasty,his achievements in collecting and reviewing ancient books of Chinese medicine and his academic thoughts on medicine.[Methods]Using the method of literature research,it summarized the medical bibliographies in SUN Congtian's Shangshantang Bibliograph,and studied Huoren Jinglun,Shizhi Medical Talk.[Results]In terms of ancient medical books,SUN Congtian collected and reviewed many ancient medical books,and put forward the idea of purchasing and collecting ancient medical books and editions.In terms of medical theory,he enlightened the student YE Tianshi's"collateral disease"theory and SHEN Jin'ao's"depression disease"diagnosis and treatment thought,and put forward the medical theory of"spleen and stomach construction".[Conclusion]SUN Congtian's Shangshantang Bibliography records 28 ancient Chinese medicine books,including many rare and precious editions.Huoren Jinglun and Shizhi Medical Talk have innovated medical theory and promoted the development of medical academia.His medical academic thought needs to be further explored and sorted out.

Objective To observe the curative effect of nursing intervention in the treatment of children with bronchial pneumonia and its effects on pulmonary function.Methods 100 children with bronchial pneumonia were selected as the research subjects,they were randomly divided into control group (50 cases) and observation group (50 cases) according to the digital table.The control group received routine nursing,the observation group received high quality nursing.The pulmonary function indicators (FVC,FEV1,PEF),the adverse reactions and the clinical curative effect were observed in the two groups after treatment.Results After treatment,the FVC,FEV1,PEF of the observation group were (3.96 ± 0.80) L,(3.15 ± 0.80) L,(6.32 ± 2.01) L/s,respectively,which were better than those of the control group [(2.85 ±0.91)L,(2.43 ±0.63)L,(4.90 ± 1.35)L/s] (t =6.478,P=0.000;t =5.000,P =0.000;t =4.147,P =0.000).The incidence rate of adverse reactions of the observation group was 14.00％ (7/50),which was lower than 38.00％ (19/50) of the control group (x2 =7.484,P =0.006).The total effective rate of the observation group was 98.00％ (49/50),which was higher than 80.00％ (40/50) of the control group (x2 =8.274,P =0.004).Conclusion To give children symptomatic treatment of infantile bronchial pneumonia at the same time,take the high quality nursing intervention can effectively improve lung function in children,reduce the incidence of complications,it is conducive to prognosis and can improve the therapeutic efficacy.

Sha （痧） is an acute infectious disease characterised by the appearance of rashes on the skin， caused by exposure to epidemic toxin and pestilent qi. Sha Zhang Yu Heng （《痧胀玉衡》） discussed the treatment principles and methods， and listed collateral bloodletting as one of the main treatments. Through organizing the articles and proved cases， we found that the author believes Sha （痧） is caused by epidemic pathogen， belonging to heat toxin with rapid changes， so timely treatment for qi and blood simultaneously could achieve the effect of transforming qi into defensive qi. Sha Zhang Yu Heng focuses on patient's position during treatmet， the material of the needle， the site of treatment， the quantum of stimulation and the operation of the contraindications and other essentials. According to the depth of the disease location， use traditional Chinese herbal medicine， scraping together to identify the root of the disease. In addition， diet suggestions for the prevention of the recrudescence of disease are also described in detail.
