Journal of Zhejiang Chinese Medical University 2013;(8):960-961,966
Today's society, many people are plagued by tinnitus and deafness. Chinese medicine on tinnitus and deafness disease and its therapies and for-mulas have discussed quite wel . It is believed that according to the features of the organs, treating tinnitus and deafness from the five internal organs is much better .The virtual is mostly related to the heart, spleen and kidney, but the real mostly related to the heart, liver and lungs. In the treatment of tin-nitus and deafness from the perspective of the kidney, attention should be paid to nourishing the kidneys and strengthening the essence. Treating from the spleen, attaches great importance to the spleen and replenishing qi, clearing material. Treatment from the aspects of liver, the first is to make qi run unob-structed, to prevent generating phlegm and fire. From pulmonary vessels, great importance should be attached to the recovery of dispersing the descending lung. Treated from heart, benefiting qi and nourishing blood should be given much attention not only to make up for its deficiency, but also attach great importance to the qi, send a fire on its reduction. Sick of longer time, compatibility on the basis of syndrome differentiation and treatment to invigorate the flux pulse, aromatic resuscitation of Chinese herbal medicine shal be used.

Methods One hundred and forty - two neonates selected from February 2009 to June 2013 in Shangqiu First People's Hospital according to the different gestational age and birth weight were divided into 3 groups. Group A included 44 cases(small for gestational age,birth weight below the average weight of the 10th percentile at the same gestational age),23 boy cases,21 girl cases;group B included 56 cases(appropriate for gestational age,birth weight at the average weight of the 10th to 90th percentile at the same gestational age),30 boy cases,26 girl cases;group C included 42 cases(large for gestational age,birth weight above the average weight of the 90th percentile at the same gestational age),22 boy cases,20 girl cases. Neonatal body mass index,birth weight,placenta weight and umbilical lep-tin levels of three groups were compared. Results Neonatal birth weight,neonatal body length,body mass index and the placenta weight leptin levels in group A were significantly lower than those of group B,having statistically significant difference(all P ﹤ 0. 001);Neonatal birth weight,neonatal body length,body mass index and the placenta weight leptin levels in group C were significantly higher than those in group B,with statistically significant difference( all P ﹤0. 001). Neonatal birth weight in the boy group was obviously higher than that of the girl group,and the difference was statistically significant(P ﹤ 0. 001). Neonatal leptin levels in the boy group were significantly lower than that of the girl group,and the difference was statistically significant(P ﹤ 0. 001). There were positive correlations between the umbili-cal cord leptin levels and the neonatal birth weight,neonatal length,neonatal weight index and the placenta weight(r =0. 382,0. 276,0. 358,0. 412,all P ﹤ 0. 01). Conclusions The umbilical cord leptin levels are closely associated with neonatal birth weight and intrauterine growth retardation,and it can be used as one of the important indicators for reflec-ting neonatal birth weight and fetal growth.
