ABSTRACT
Objective To learn the changes of blood lead levels and serum biochemical parameters of the school agechildren from different areas. Methods All research objects, the school age children, were from three different areasrespectively, including a mountainous area (L area), an island area (H area) where there is not history of Pb pollution,and an industry area (N area) in relation to Pb pollution. The morning urine and peripheral venous blood samples werecollected from the school age children. Pb in blood (PbB), δ-aminoaevulinic acid in urine (ALA), Ca2+, BUN, Cr inserum, and Thyroid Stimulating Hormone (TSH), thyroxin (T4), free thyroxin (FT4) levels were detected. ResultsPbB levels [M was 36.0 ppb] of the school age children from N area were significantly higher than that of L area [22.0 ppb] andH area [23.8 ppb]. On the contrary, serum Ca2+ levels of the school age children from N area were significantly lower than thatof L area and H area. Serum T4 of N area was significantly lower than that of L area and H area. Serum FT4 of H area wassignificantly higher than that of L area and N area. And TSH of N area and H area were both obviously lower than that of L area.But all of these thyroxin indexes were in the range of normal values. Conclusion It should be widely concerned that thesignificant elevation of PbB levels may have a negative impact on school age children in the future.
ABSTRACT
<p><b>OBJECTIVE</b>To observe acupuncture at Jiquan (HT 1) with different manipulations for improvement of abnormal sensation of the upper limb induced by cervical spondylosis of nerve root type.</p><p><b>METHODS</b>One hundred and seven cases were randomly divided into 3 groups. The lifting-thrusting group (n = 37) were treated with acupuncture at Jiquan (HT 1) with lifting-thrusting manipulation, the twirling group (n = 36) with acupuncture at Jiquan (HT 1) with twirling manipulation and the routine needling group (n = 34) with acupuncture at C4 - T1 Jiaji (EX-B 2), Quchi (LI 11).</p><p><b>RESULTS</b>The total effective rate of 91.9% in the lifting-thrusting group was significantly better than 58.3% in the twirling group (P < 0.005) and 76.5% in the routine needling group (P < 0.05), and the therapeutic effect of the twirling group was similar to that in the routine needling group CP > 0.05).</p><p><b>CONCLUSION</b>Acupuncture at Jiquan (HT 1) with lifting-thrusting manipulation can obviously improve abnormal sensation of the upper limb induced by cervical spondylosis of nerve root type.</p>
