OBJECTIVE:To establish the quality standards for Qiqilian capsule. METHODS:TLC was used to identify the As-tragali Radix,Phellodendri chinensis,Coptidis rhizom. HPLC was used to determine the contents of ginsenosides Rg1,ginsenosides Rb1 and notoginsenosides R1. The column was Shim-pack VP-ODS C18 with mobile phase of acetonitrile-water(gradient elution) at flow rate of 1.0 ml/min,detection wavelength was 203 nm,column temperature was 20 ℃. RESULTS:TLC of Astragali Radix,P. chinensis,C. rhizom showed cleer sports and good separation. The linear range was 0.9-9.0 μg for ginsenosides Rg1,0.94-9.4 μg for ginsenosides Rb1 and 0.3-3.0 μg for notoginsenosides R1(r≥0.999 5);RSDs of precision,reproducibility and stability test were lower than 3.0%;recoveries were 96.08%-99.75%(RSD=1.52,n=6),97.03%-99.75%(RSD=1.10,n=6)and 96.38%-98.55%(RSD=0.90,n=6),respectively. CONCLUSIONS:The method is simple,good reproducibility,and can be used for the quality control of Qiqilian capsule.

Objective To understand the situation of off-label use of sildenafil, so as to provide reference for developing off-label drug use policy. Methods A stratified random sampling method was used to collect prescription data of sildenafil in Guangdong Women and Children Hospital in 2015. The off-label drug use situation was analyzed according to drug labels. The situations of drug use in all departments were summarized, and off-label drug use occurrences were analyzed.Results A total of 1044 prescriptions with sildenafil were collected and analyzed to discover the occurrence of off-label use was up to 69. 54%. The top 3 departments of off-label use of sildenafil were assisted reproductive center, heart center and neonatal intensive care unit (NICU). The top 3 types of off-label use were non-indication(50. 35%), over drug population(31. 76%) and over drug administration(17. 89%). The top 3 diseases for non-indications were infertility, pulmonary hypertension and congenital heart disease. Conclusion Sildenafil off-label use was common in Guangdong Women and Children Hospital in 2015, especially in assisted reproductive center, heart center, and NICU. The result suggests that more clinical studies about sildenafil on cardiovascular system are expected to provide more evidence for drug use, so as to ensure the safety of drug use in special populations and avoid potential medical risk.

Objective To investigate the state of Th1/Th2 cytokine imbalance in patients with lupus nephritis (LN) and its role in the pathogenesis. Methods Plasma level of interleukin-18 and interleukin-13 in 18 patients with active LN and 16 normal controls were measured by enzyme-linked immunoadsordent assay (ELISA). IL-18 and IL-13 expression in the renal tissues from 18 patients and 6 normal renal tissues were also detected by immunohistochemical assay. The ratio of plasma and renal IL-18/IL-13 was then calculated. Results Plasma levels and renal expression of IL-13 and IL-18 in patients with LN were increased significantly compared to those of normal controls (P0.05). The ratio of renal IL-18/IL-13 was not significantly different among all types of LN and normal controls. The ratio of plasma IL-18/IL-13 was positively correlated with LN renal tissue activity index (AI), but no correlationship could be found in renal IL-18/IL-13 ratio. Conclusion It seems that the immune disturbance in systemic lupus erythematosus (SLE) can not be simply divided into Th1 predominant and Th2 predominant. It seems far complicated than this Th1/Th2 paradigm. It may be affected by the state of disease activity, the lesion location and the type of pathology.

Objective To explore the effect of transitional care model (TCM) on the prevention of complications in patients with severe cerebral infarction. Methods Sixty patients with severe cerebral infarction were randomly divided into the experiment group and the control group, 30 cases in each group. The control group was given conventional nursing and the observation group received TCM. The two groups were compared in terms of the incidence of complications and re-admission rate. Result The incidence of complications and the rate of re-admissions in the experiment group were significantly lower than those of the control group (P<0.05). Conclusion TCM can reduce the incidence of complications in patients with severe cerebral infarction, lower the incidence of hospital admission, relieve the pain of patients and improve the quality of life of patients.

Objective To explore the interactive teaching model for CT imaging based on PACS, and provide the clinician and young radiologist with continued medical education. Methods 100 M trunk net was adopted in PACS and 10 M was exchanged on desktop. Teaching model was installed in browse and diagnosis workstation. Teaching contents were classified according to region and managed according to branch model. Text data derived from authoritative textbooks, monograph , and periodicals. Imaging data derived from cases proved by pathology and clinic. The data were obtained through digital camera and scanner or from PACS. After edited and transformed into standard digital image through DICOM server, they were saved in HD of PACS image server with file form. Results Teaching model for CT imaging provided kinds of cases of CT sign, clinic characteristics, pathology and distinguishing diagnosis. Normal section anatomy, typical image , and its notation could be browsed real time. Teaching model for CT imaging could provide reference to teaching, diagnosis and report. Conclusion PACS based teaching model for CT imaging could provide interactive teaching and scientific research tool and improve work quality and efficiency.
