[Soil Carbon Pool Allocation Dynamics During Soil Development in the Lower Yangtze River Alluvial Plain].

The allocation dynamics of soil carbon pools during soil development and land use are the key to revealing the carbon cycle process. To clarify the distribution of the soil carbon pool and its change trend, a soil reclamation chronosequence (0 a, 60 a, 160 a, 280 a, 1 000 a, and 1 500 a reclamation) was established in a typical alluvial plain in the Lower Yangtze River, and the content and density of soil organic carbon (SOC), soil inorganic carbon (SIC), particulate organic carbon (POC), and mineral-associated organic carbon (MAOC), along with carbon sequestration potential (CSP) indicators of topsoil under different land use types were measured and analyzed. The results showed that after approximately 1 500 a reclamation, the SOC content developed from the Yangtze River alluvial deposits generally increased by 4.

[Analysis on the distribution of pressure- and heat-sensitive acupoints in patients with allergic rhinitis].

Objective: To explore the distribution of pressure- and heat-sensitive acupoints of the Large Intestine of Hand-Yangming, Stomach Meridian of Foot-Yangming and the Lung Meridian of Hand-Taiyin below the elbow and knee joints in patients with allergic rhinitis, so as to explore the positive reaction points at the body surface of allergic rhinitis.

Methods: Thirty variant rhinitis volunteer subjects and 30 healthy subjects were recruited in the present study. The subcutaneous induration, reaction points of emptiness-like feeling or pressing pain below the elbow- and knee-joints along the Large Intestine Meridian, Stomach Meridian and the Lung Meridian were inspected first, then re-examined by using heat-sensitized moxibustion method and a hand-held pain threshold tester (mechanical pressure), respectively.
