Objective To understand the impact of the clinic-pharmacy separation reform on a tertiary hospital in Beijing.Methods In a comparative analysis,data in the HIS of the hospital were analyzed in descriptive statistics,covering such data as the number of visits,expense per visit,medical income and income structure change in the period between June and December in 2016 and 2017,and were analyzed by the methods of t test and descriptive statistics as well.Results Compared with the same period between June and December in 2016,the number of visits at its outpatient department reduced by 12.06％,expense per visit increased by 31.42 yuan (P ＜ 0.05),while the expense per visit of patients with medical insurance increased by 28.51 yuan (P ＜ 0.05) between June and December in 2017.The number of hospitalizations at the inpatient department increased by 2.94％,expense per hospitalization increased by 877.71 yuan,and that of patients with medical insurance decreased by 42.87 yuan (P ＞ 0.05)between the abovementioned periods.The case mixed index of inpatients rose by 0.01,and patient satisfaction rose by 4.22 percentage points.Conclusions This reform has reduced outpatient visits at hospitals,increased the coefficient of difficulty of hospital inpatients,and improved patients' experiences for medical services.Hospitals are recommended to further their internal management in a fine manner,and curb unreasonable growth of medical expenses.

Objective To explore the influence factors of recurrence after a first unprovoked seizure in adults within 1 year. Methods One hundred fifty-nine adult patients with first unprovoked seizure were recruited in the study. Patients were then divided into the relapse group (n=54) and the relapse group (n=105). Statistic analysis was performed on the clinical data including gender, age, history of traumatic brain injury, electroencephalogram (EEG) and brain imaging, the form of attack time, seizures, diabetes mellitus, hypertension, coronary heart disease, hyperlipidemia disease. Results Multiariable Logistic regression analysis found that history of brain injury (P=0.033, OR=5.547), period (P=0.001, OR=33.660) in the evening, cortical lesions (P=0.004, OR=14.865) were independent risk factors for recurrence. Conclusions Adult patients with first unprovoked seizure have a high risk of one-year recurrence if the patients have a history of traumatic brain injury, the radiographic abnormalities, cortical lesions and sleep attacks.

Objective To study the cyclic peptides from sponge Reniochalina sp. under the guidance of mass spectrometry. Methods Mass spectrometry-guided procedural separation methods were used to track and isolate the cyclic peptides from the sponge genus Reniochalina. The structures of compounds were elucidated by the determination of physicochemical parameters and comparison of spectroscopic data. The preliminary cytotoxic activity of compounds was assessed by the Cell Counting Kit-8 (CCK-8) method. Results Three cyclic peptides were isolated from the sponge Reniochalina sp. and identified as stylopeptide 1 (1), hymenamide D (2) and axinastatin 2 (3). Compound 1 exhibited cytotoxicity against six human cancer cell lines with IC₅₀ values ranging from 6.09 to 17.26 μmol/L. Conclusion Compound 1 - 3 were isolated from Reniochalina sp. for the first time, and compound 1 was a cytotoxic cyclic heptapeptide.
