Background: Developmental dysplasia of the hip (DDH) is a common osteoarticular deformity in pediatric orthopedics. A patient with bilateral DDH was diagnosed and treated using our improved technique "(powerful overturning acetabuloplasty)" combined with femoral rotational shortening osteotomy.

Case Summary: A 4-year-old girl who was diagnosed with bilateral DDH could not stand normally, and sought surgical treatment to solve the problem of double hip extension and standing.

Article Synopsis
  • A scientific evaluation of ecosystem service value (ESV) highlights the benefits of using cover crops in maize cultivation in Northeast China, specifically comparing different intercropping systems to maize monoculture.
  • The study found that cover crop intercropping resulted in significantly higher ESVs, particularly in nutrient cycling and product supply, suggesting these practices enhance ecosystem benefits.
  • Intercropping with leguminous cover crops like alfalfa and hairy vetch showed the most potential for increased ESV, especially in nutrient cycling and product supply, compared to gramineous cover crops like ryegrass.

The aim of the present study was to investigate whether curcumin (CUR) can ameliorate cadmium-induced reproductive toxicity and its mechanism. A total of 48 male mice were equally divided into 4 groups: control, CdCl (2 mg/kg, intraperitoneally inject) curcumin (50 mg/kg, intraperitoneally inject), co-treatment with curcumin (50 mg/kg), and CdCl (2 mg/kg) for 10 days. The results demonstrated that CdCl reduces sperm motility, decreases the sperm density and serum testosterone content, and significantly improves the rate of sperm deformity.

Cadmium (Cd) is harmful for humans and animals, especially for the reproductive system. However, the mechanism of its toxicity has not been elucidated, and how to alleviate its toxicity is very important. This study aimed to explore the role and mechanism of action of sulforaphane (SFN) in protecting mouse Leydigs (TM3) cells from cadmium (Cd)-induced damage.

Sulforaphane (SFN) is a natural and highly effective antioxidant. Studies suggest that SFN protects cells and tissues against cadmium (Cd) toxicity. This study investigated the protective effect of SFN against oxidative damage in the testes of Kunming mice exposed to cadmium, and explored the possible molecular mechanisms involved.
