Establishing a novel lens opacities classification system based on ultrasound biomicroscopy (UBM) for pediatric cataracts: reliability and availability.

Background: This study sought to develop and validate a lens opacities classification system based on ultrasound biomicroscopy (UBM) imaging to grade pediatric cataracts.

Methods: The study was conducted at Guangzhou Children's Hospital, Guangzhou Women and Children's Medical Center. UBM images of patients at the hospital from September 2013 to November 2014 were used in this study.

Ultrasound Biomicroscopy Detects Peters' Anomaly and Rieger's Anomaly in Infants.

Aim: Congenital corneal opacities (CCOs) are the major causes of early visual deprivation in infants. Balloon ultrasound biomicroscopy (UBM) examination is an effective method to diagnose CCO. However, whether it is suitable for children examination is still unknown.

[Effects of Semen Ziziphi Spinosae extracts on body temperature and weight gain of chickens in hot environment].

Objective: To validate the decreasing body temperature effect of Semen Ziziphi Spinosae extracts (SZSE) on chickens in hot environment and study its functions of sunstroke and hot-stress prevention.

Methods: Ninety 1-day-old San-huang chickens were randomly divided into air-conditioning group, hot-treatment group,and SZSE group. The feed for SZSE group was added SZSE as 1 g/kg.

[CpG oligodeoxynucleotide enhances humoral and cellular immune responses against HBsAg in mice].

Objective: To induce stronger humoral and cell mediated immune response against HBsAg and seek more effective methods to treat hepatitis B virus infection.

Methods: 21-mer phosphorothioate oligodeoxynucleotide (ODN) and its control ODN were synthesized and used as an adjuvant of HBsAg and commercial hepatitis B vaccine to enhance their immune responses against HBsAg. Four groups of 33 mice received 2 doses of the mixtures (1.

[Reciprocal priming-boosting role of HBsAg and DNA vaccines].

Objective: To evoke more effective humoral and cell-mediated immunization against hepatitis B virus (HBV) infection.

Methods: HBsAg-primed mice were boosted with HBs-DNA vaccine, and HBs-DNA-primed mice were boosted with HBsAg vaccine. Anti-HBs level was assayed by ELISA and cytotoxic T lymphocyte (CTL) response was tested by lactic acid dehydrogenase (LDH) releasing method two weeks after the boosted immunization.
