Objective To investigate the safety of thyroid gland resection and primary resection in the treatment of thyroid nodule and its influence to thyroid function.Methods 86 patients with thyroid nodules were selected as the research subjects.The patients were randomly divided into two groups.43 cases in the observation group implemented the thyroid gland resection treatment.43 cases in the control group received thyroid gland subtotal resection.The curative effect,safety,thyroid function and other indicators were compared between the two groups.Results The operation time and hospitalization time in the observation group after operation[(105.65 ± 12.54)min;(6.35 ± 2.01)d]were shorter than those in the control group[(149.41 ± 13.68)min;(9.62 ± 2.45)d].The amount of bleeding during operation in the control group [(134.51 ± 9.64) mL] was significantly higher than the observation group [(84.62 ± 6.35) mL],there was significant difference between the two groups (P ＜ 0.05).The total effective rate of the observation group was 95.55％,which was significantly higher than 72.09％ in the control group,the difference was statistically significant (P ＜ 0.05).Before operation,the between the two groups had no significant difference (P ＞ 0.05).After surgical treatment,serum FT3 and serum FT4 levels in two groups were decreased,but those in the observation group[(11.62 ± 3.02),(51.24 ± 7.25)pmol/L] were significantly lower than the control group [(14.14 ± 5.11) pmoL/L;(60.52 ± 6.35) pmol/L],there were obvious differences (P ＜ 0.05).The incidence rate of complications such as throat edema,hemorrhage,postoperative hoarseness in the observation group was 9.30％,which in the control group was 23.26％,the difference was statistically significant (P ＜ 0.05).Conclusion The thyroid gland resection therapy for thyroid nodules has high safety and significant curative effect,it can quickly improve the thyroid function,reduce relapse rate,has higher application value in benign and malignant tumors indistinguishable after surgery.It can reduce the length of stay in hospital,is conducive to the recovery of patients,it is worthy of clinical promotion.

Objective To investigate the antitumor effect of special promoter-controlled Gibbon ape leukemia virus membrane fusion glycoprotein (GALV.fus) mediated by type Ⅰ herpes simplex virus (HSV-Ⅰ) on lung adenocarcinoma. Methods Recombinant HSV-Ⅰ plasmids encoding GALV.fus was introduced into green monkey kidney cells(Vero)by liposome to amplify the virus, and then the virus was transfected into lung adenocarcinoma (A549), human fetal fibroblasts (HFL-Ⅰ GNHu 5) and human lung adenocarcinoma xenografts which were established in nude mice subcutaneously to observe antitumor and cytotoxic effect in vitro and in vivo; Recombined cytomegalovirus (CMV) containing GALV.fus or enhanced green fluorescence protein were served as control. Results Recombinant HSV-Ⅰ virus were packed successfully. Heterotransplantative tumourigenicity of the tumour was 100% in nude mice after A549 cells were inoculated. Recombinant HSV-Ⅰvirus exerted obvious antitumor effects in vitro, with relative survival rate of 23%, while for CMV virus containing GALV. fus, the rate was 20%, and for CMV virus encoding EGFP, the rate was 68%. Recombinant HSV-Ⅰvirus also showed striking antitumor effect on the implanted tumor. Conclusion GALV.fus has powerful effect against lung cancer in vitro and in vivo and maybe a promising candidate for gene therapy.
