Chinese Journal of Primary Medicine and Pharmacy 2014;21(8):1187-1188
Objective Comparison of the effects of erythromycin or azithromycin in the treatment of children bronchial pneumonia.Methods 87 cases of bronchial pneumonia were randomly divided into two groups.The observation group had 46 cases treated with azithromycin.The control group had 41 cases treated with erythromycin.The clinical curative effect and adverse reaction of two groups were compared.Results Total effective rate in the observation group(93.5%) was significantly higher than that of the control group (60.9%) (x2 =13.42,P < 0.01) ; the incidence of adverse reactions in the observation group (10.9%) was significantly lower than that of the control group (60.9%) (x2 =24.09,P < 0.01).Conclusion The curative effect of azithromycin is better than erythromycin on children bronchial pneumonia,and less adverse reaction.

Chinese Pharmacological Bulletin 2014;(9):1325-1328
Aim To establish and evaluate a mouse model of my-ocardial fibrosis by hypodermic injection of isoprenaline. Meth-ods Kunming mice were randomly divided into 2 groups, namely, the myocardial fibrosis model group and the control group, 10 mice in each group. The mice in the model group were given isoprenaline 5 mg · kg-1 by hypodermic injection. From the following day, the dose of isoprenaline was reduced to 2. 5 mg·kg-1 , and lasted for 30 days. The mice in the control group were treated with the physiological saline in the same way. Final-ly, heart weight was then weighed and the cardiac weight index (CWI) was calculated. Hydroxyproline (Hydro) level in myo-cardium was determined by a colorimetric method. HE and Mas-son’s trichrome staining were used to estimate the extent of myo-cardial fibrosis and calculate the collagen volume fraction ( CVF) . RT-PCR was used to measure the myocardial Collagen I mRNA expression. Results Compared with the control group, the CWI and Hydro content in the myocardial tissues in the model group were increased(P<0.01). The content of col-lagen in the myocardial tissues and the CVF were increased obvi-ously(P<0.01). The RT-PCR results showed that the left ven-tricle Collagen I mRNA expression in the model group increased obviously( P<0.01 ) . Conclusion Isoprenaline-induced myo-cardial fibrosis model has been established and the method is very simple, economic and reliable.
3.Advance in Imaging in Vascular Cognitive Impairment(review)
Chinese Journal of Rehabilitation Theory and Practice 2009;15(10):945-947
Vascular cognitive impairment is the most common type of cognitive dysfunction. Imaging of nervous system presents important references for the research of cognitive impairment and helps to identify different types of dementia, detect symptoms of dementia early or timely, and make a follow-up study on patient's condition progress so as to assess brain function in patients before and after treatment. Therefore, imaging of nervous system will make ever greater contributions to the study of vascular cognitive impairment.
4.Effects of Early Goal-directed Therapy Combined with Yiqi Fumai Lyophilized Powder on P(cv-a) CO2 and S(cv)O2 in Patients with Septic Shock.
Chinese Journal of Integrated Traditional and Western Medicine 2016;36(3):306-309
OBJECTIVETo explore the effect of early goal-directed therapy (EGDT) combined with Yiqi Fumai Lyophilized Powder (YFLP) on central venous-arterial carbon dioxide difference [P(cv-a)CO2] and central venous oxygen saturation (S(cv)O2) in patients with septic shock.
METHODSTotally 50 patients with septic shock were assigned to the control group and the treatment group according to random digit table, 25 cases in each group. Patients in the control group received treatment according to EGDT principle. Those in the treatment group were intravenously injected with YFLP (5.2 g adding in 500 mL normal saline) additionally. Changes of P(cv-a)CO2, S(cv)O2, lactic acid, central venous pressure (CVP), mean arterial pressure (MAP), and APACHE II score were observed in the two groups before and after treatment. The 6-h success rate and 28-day mortality were also observed.
RESULTSCompared with before treatment in the same group, lactic acid and APACHE II score decreased, levels of S(cv)O2, MAP, CVP increased in the two groups after treatment (P < 0.01). P(cv-a)CO2 decreased more obviously after treatment in the treatment group, and lower than that in the control group after treatment (P < 0. 05, P < 0. 01). The 6-h success rate was 48% (12/25) in the control group and 76% (19/25) in the treatment group (P < 0.05). The 28-day mortality was 36% (9/25) in the control group and 12% (3/25) in the treatment group (P < 0.05).
CONCLUSIONEGDT combined with YFLP could significantly elevate S(cv)O2, decrease P(cv-a)CO2 and mortality in patients with septic shock, and obviously improve the clinical effect.

5.Application of Positron Emission Computed Tomography in Treatment of Cerebral Infarction (review)
Chinese Journal of Rehabilitation Theory and Practice 2014;(4):340-343
Cerebral infarction is caused by cerebral blood supply disturbance, and then results in cerebral hypoxic ischemic lesions, with the manifestation of neurofunction deficit. This article summarized the application of positron emission computed tomography in treat-ment of cerebral infarction.
6.Epilepsy in children:the impact on cognitive function
International Journal of Pediatrics 2014;(5):473-475
Cognitive function has become a hot spot in the field of epilepsy. However,the relationship between cognitive function and epilepsy has not been clearly demonstrated. Clinical trials have showed that epi-lepsy and epileptic relevant factors are both associated with cognitive function in children. Children with cogni-tive impairment are often caused by those two factors. This article focuses on cognitive function in children with epilepsy age below 6 years,and mainly reviews the characteristics of cognitive function in these children with epilepsy.

In this paper, basic characteristics of group purchasing organizations ( GPOs) and its implications for US health care system are analyzed using a literature research method. The main contents include the development process, type, basic functions, drug procurement processes, fee sources, characteristics and influence for the hospi-tals, supplies, regulators of GPOs. We suggest that GPOs have helped US health care providers save a lot of money and played an important role in the healthcare supply chain. We also suggest that market mechanisms should be intro-duced widely concerning the model innovation and improvement of domestic drug procurement. At the same time, government and the market should be coordinated properly. Moreover, scientific evaluation methods should be set in consideration of drug quality, prices and its economic practicality.
