Objective:To investigate the effects of recombinant human growth hormone on bone metabolism, insulin-like growth factor-1 (IGF-1) and vitamin D3 in dwarfism children at different ages.Methods:Sixty children with dwarfism who received treatment in Shaoxing Women's and Children's Health Care Hospital from January 2018 to January 2019 were included in this study. They were divided into group A (age at 4-9 years, n = 32) and group B (age at >9-13 years, n = 28) according to different ages. Two groups of children were treated with recombinant human growth hormone for 6 months. Total effective rate in two groups was recorded. Before and after treatment, bone metabolism index, serum IGF-1 and 25-hydroxyvitamin D3 levels were measured in each group. Results:Total effective rate in the group A was significantly higher than that in the group B [90.62% (29/32) vs. 67.85% (19/28), χ2 = 4.838, P < 0.05]. Before treatment, there were no significant differences in serum levels of calcium, phosphorus, zinc, IGF-1 and 25 hydroxyvitamin D3 between groups A and B (all P > 0.05). After treatment, serum levels of calcium, phosphorus, zinc, IGF-1 and 25 hydroxyvitamin D3 in the group A were (1.99 ± 0.53) mmol/L, (1.76 ± 0.14 ) mmol/L, (88.97 ± 6.89) μmol/L, (325.57 ± 15.29) ng/L, (89.47 ± 15.58) ng/L, respectively,which were significantly higher than those in the group B [(1.71 ± 0.55) mmol/L, (1.65 ± 0.15) mmol/L, (85.22 ± 6.76) μmol/L, (312.29 ± 13.88) ng/L, (80.11 ± 15.31) ng/L, t = 2.005, 2.936, 2.121, 3.502, 2.340, all P < 0.05]. Conclusion:Recombinant human growth hormone has better curative effect on dwarfism in children at 4-9 years old than in children at 9-13 years old, and it can effectively improve bone metabolism, IGF-1, vitamin D3 and other indicators.

This paper presents the experience of surgical treatment of 32 patients with esophageal stricture caused by corrosive burn. The modes of surgical treatment in this series included: instrumental dilatation in 11 cases, reconstruction with resection of strictured esophagus in 19 (pharyngogas-trostomy in 6, cervical esophagogastrostomy in 12 and colon interposition in 1) and reoperation for esophageal restenosis in 2, There was no operative morality. All patients were fol- lowed-up and 94% of them resumed their normal diet post-operatively. The author recommend that dilatation can be applied to patients with localized esophageal stricture or slight annular stricture, and should done early. Resection of the esophageal stricture and esophagal reconstruction can be used in patients with extensive or severe stricture. There are many ways to esophageal reconstruction. The optimal one should meet the following requirements: isoperistaltic segment without tension and rich in blood supply, it should be easy to perform and result in no restenosis.

Objective To investigate the pathologic characteristics of skip metastases of mediastinal lymph node in lung cancer. Methods Of 398 lung cancer patients who underwent radical resection and extensive lymph node dissection. 47 patients were diagnosed as with skip N 2 metastases, and their mediastinal lymph nodes were analyzed. Results The skip N 2 metastases of lung cancer appeared as single group or multi-group. The commonest metastatic site was the 7th group lymph node (28.4%), then the 4th, 3rd and 5th group, rating 24.2%, 15.8% and 10.5%, respectively. For cases with squamous cell carcinoma or adenocarcinoma, no any skip N 2 metastasis occurred for the tumor less than 1 cm in diameter, for tumor greater than 1 cm in diameter, the skip N 2 metastasis increased with tumor size. The incidence skip N 2 metastasis of low-grade differentiated adenocarcinoma was significantly higher than high-grade differentiated adenocarcinoma (P
