Developmental expression of calretinin in the mouse cochlea.

This study investigated the expression of calretinin (CR) in the mouse cochlea from embryonic day 17 (E17) to adulthood through immunofluorescence. At E17, CR immunoreactivity was only detected in the inner hair cells (IHCs). At E19, the IHCs and spiral ganglion neurons (SGNs) begin to express CR.

[Association of the H770H of PR gene polymorphism with susceptibility to endometriosis].

Objective: To investigate the association of PR gene exon 5 region H770H (rs1042839) single nucleotide polymorphism (SNP) with the genetic susceptibility to endometriosis (EM) in southern Han Chinese women.

Methods: Totally 431 EM patients and 499 non-EM women were collected and separated into EM group and control group, that all cases were confirmed by operation and pathology. A case-control study was performed in EM and control groups to evaluate the association of these SNP with the susceptibility to EM by using a fluorescent quantitative PCR-based high resolution melting (HRM) method.

[Survey of health status and healthcare service demand of perimenopausal women in Guangdong].

Objective: To understand the health status and healthcare service demand of perimenopausal women in Guangdong Province so as to explore the mode and methods for implementing climacteric and senectitude healthcare.

Method: Using the method of stratified and cluster sampling and according to the geographical features of Guangdong Province, we selected 4 500 perimenopausal women aged 40-65 years from 5 relatively small cities (representatives of the urban areas) and 4 counties (representatives of the rural areas) for this survey.

Results: The average age of natural menopause was 48.
