[Clinical Significance of Screening Thalassemia with High- Throughput Sequencing].

Objective: To evaluate the diagnostic value of high-throughput sequencing (NGS) in screening the thalassemia genes.

Methods: The peripheral blood of 2 858 cases of pre-pregnancy and pregnancy from October 2014 to October 2016 randomly were collected in department of obstetrics, the third people's hospital in Dongguan city. Peripheral blood was used for the blood routine examination, hemoglobin electrophoresis, traditional thalassaemia gene screening and NGS.

Bacillus vanillea sp. nov., Isolated from the Cured Vanilla Bean.

A Gram-positive bacterium, designated strain XY18(T), was isolated from a cured vanilla bean in Hainan province, China. Cells were rod-shaped, endospore producing, and peritrichous flagella. Strain XY18(T) grew at salinities of 0-8 % (w/v) NaCl (optimally 1-4 %), pH 4.

Volatile organic compound emissions from different stages of Cananga odorata flower development.

Headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) was used to identify the volatile organic compounds (VOCs) of the different flower development stages of Cananga odorata for the evaluation of floral volatile polymorphism as a basis to determine the best time of harvest. Electronic nose results, coupled with discriminant factor analysis, suggested that emitted odors varied in different C. odorata flower development stages, including the bud, display-petal, initial-flowering, full-flowering, end-flowering, wilted-flower, and dried flower stages.

[A preliminary study on the occlusal contact changes during retention in adolescent patients].

Objective: To evaluate the changes of the occlusal contact characteristics in adolescent patients during 12 months after active orthodontic treatment.

Methods: Twenty adolescent patients with Hawley retainers after active orthodontic treatment were divided into none occlusal interference group and occlusal interference group. The occlusion of the patients was examined with T-Scan II system directly after the appliance removal (T1) and after an average retention period of 12 months (T2).

[Influence of interventional radiotherapy for severe postpartum hemorrhage on postpartum menorrhea].

Objective: To discuss the influence of interventional radiotherapy for treating severe postpartum hemorrhage on postpartum menorrhea.

Methods: From Mar. 1995 to Feb.
