Assessment of Prognostic Factors of Racial Disparities in Testicular Germ Cell Tumor Survival in the United States (1992-2015).

Objective: Testicular germ cell tumors (TGCT) are the most common cancer among men aged 15 to 39 years. Previous studies have considered factors related to TGCT survival rate and race/ethnicity, but histological type of the diagnosed cancer has not yet been thoroughly assessed.

Methods: The data came from 42,854 eligible patients from 1992 to 2015 in the Surveillance Epidemiology and End Results 18.

The nationwide impact of injury-related deaths on average life expectancy in China.

To expand the evidence base to inform future public policy aimed at accident prevention, we investigated the impact of different categories of injury on average life expectancy in China. We used data from the National Death Cause Registration Information System and National Maternity and Children Health Surveillance databases, as well as 2010 population data from the National Bureau of Statistics. We then calculated the average life expectancy of the Chinese population, in addition to life expectancy after eliminating injury-related mortality.

[Exploratory development of automated coding software on the underlying causes of death].

To develop an automated coding software related to the underlying causes of death, based on the National Registration Information System on deaths, which could improve the quality of coding on the underlying causes of death in the conventional death surveillance system. Following the coding rules of the underlying death cause of ICD-10 and the design on principles of software of underlying death cause automated coding from some other countries, as well as in accordance with the coding strategy table from the USA, we implemented the automatization of the underlying death cause coding. Based on national registration information system on cause of death, an automated coding software of underlying death cause was developed with the coding correction rate closed to 85%.

Sequential uniform designs for fingerprints development of Ginkgo biloba extracts by capillary electrophoresis.

A sequential procedure for the method of development of fingerprints based on a uniform design approach has been described in this paper. The sequential uniform design is used to reach the global optimum for a separation. The procedure is illustrated through developing the fingerprint of a Ginkgo biloba extract by capillary electrophoresis (CE) with diode array detection (DAD).

Development, optimization and validation of a fingerprint of Ginkgo biloba extracts by high-performance liquid chromatography.

A four-step development, optimization and validation strategy for high-performance liquid chromatography (HPLC) fingerprints of Ginkgo biloba extract is described. A suitable chromatographic system was selected first. The following step was performing a screening design to select important parameters.
