Insulin-like growth factor receptor type 1 (IGF-1 R) is the receptor cascade effect molecules of IGF signaling pathways in the hypothalamus-pituitary-growth hormone axis.In recent years,IGF-1R gene mutation of short stature case reports increased year by year,now the progress of IGF-1R gene defects in short stature for clinicians was summarized.

Antimutagenic effect of p-aminobenzoic acid (PABA) and sodium bisulfite (NaHSO_3)on the mutagenicity of N-methyl-N-nitro-N-nitrosoguanidine (MNNG) was detected by the mehod of human lymphocytes unscheduled DNA Sythesis (LIDS). The results showed that when the concentration of PABA and NaHSO_3 was varied in presence of a constant concentration of MNNG, 5 ?10~(-5) mol/L concentration of PABA, 3 ? 10~(-4) mol/L concentration of NaHSO_3 were the most effective, while the concentration of MNNG varied in the presence of a constant concentration of PABA and NaHSO_3, antimutagenicity was the most effective at high concentration of MNNG. The results indicated that the PABA and NaHSO_3 exhibited antimutagenic activity towards MNNG-induced mutagenicity in LIDS and the extents of antimutagenicity were related with the concentration of MNNG.

Objective To study the effect of FSH on the secretion of gastrin in the rat stomach,offering experimental evidence for reproductive endocrine hormone regulating digestive function. Methods The FSH was directly injected into the stomach of rats to observe the change of density of gastrin immunoreactive positive cells in the stomach by immunohistochemical SABC method and the gastrin level in circulating blood and gastric liquid by ELISA. Results Compared with the control group,which was injected with saline into the stomach,the density of immunoreactive positive cells was significantly increased in the stomach with FSH treatment group(P

Objective To explore the effect of early systemic phased exercise post mastectomy on the recovery of activities of daily living. Methods 100 patients who received modified radical mastectomy were assigned to the experimental group and control group with 50 patients in each group. They all accepted routine nursing, and the experimental group accepted early systemic phased exercise in addition. They were assessed with range of motion (ROM) of shoulder and modified Barthel Index (MBI). Results ROM of shoulder improved in 90% of the experimental group and 70% of the control group (P<0.05). MBI was (84.5±18.2) in the experimental group and (51.8±16.6) in control group (P<0.05) . Conclusion Early systemic phased exercises may promote the recovery of the affected arm for the patients post mastectomy.

Objective To evaluate the clinical outcomes of treating Freiberg's disease with dorsal wedge osteotomy and Charlotte breakage screw fixation.Methods From June 2010 to June 2014,11 patients with Freiberg's disease were treated at our department.They were 5 males and 6 females at an average age of 32 years(range,from 15 to 52 years).X-ray revealed osteosclerosis and collapse of the metatarsal head.According to Smillie classification system,there were 5 cases of stage Ⅱ and 6 ones of stage Ⅲ.The duration of symptoms was from 7 to 48 months (average,23 months).The metatarsal heads were rotated to reconstruct the joint surface.After dorsal closed V-shaped osteotomy,Charlotte breakage screws were implanted.Results All wounds healed with no complications in the early postoperative period.The 11 patients were followed up for 14 to 48 months (average,19 months),showing obvious pain relief.X-ray showed that the osteotomy sites got solid union in all patients at an average time of 10 weeks (range,from 8 to 13 weeks) after operation.Average shortening of the metatarsal was 1.5 mm (range,from 1.1 to 1.8 mm).The American Orthopaedic Foot and Ankle Society(AOFAS) score,Lesser Metatarsophalangeal-Interphalangeal Scale(LMIS) score,and range of motion at one day,one month and one year after operation were significantly improved compared with the preoperative ones (P ＜ 0.05).Significant differences were also observed between all postoperative time points (P ＜ 0.05).No such complications happened as referred pain from the adjacent metatarsophalangeal joint,displacement,nonunion,necrosis or infection.All patients returned to sports and recreational activities at 6 months after operation,except one case of stage Ⅲ who had constant swelling in the metatarsophalangeal joint but eventually recovered at 10 months after operation.According to patients' satisfaction at the last follow-ups,including 7 cases were excellent,3 good and one poor.Conclusion Dorsal closed V-shaped osteotomy with Charlotte breakage screw fixation is an effective procedure for Freiberg' s disease of stages Ⅱ and Ⅲ,because it leads to effective reconstruction of the metatarsophalangeal joint,allows early joint motion and avoids a second operation.

Objective To observe the localization and distribution of follicle stimulating hormone receptor(FSHR) in the rat submandibular gland and stomach. Methods Immunohistochemical SABC method was used in the experiment. Results The serous glandular cells,granular convoluted epithelial cells and all other duct epithelial cells in the submandibular gland and the parietal cells of gastric gland showed FSHR positive immunoreactivity.The positive substance was distributed in the cytoplasm with negative nuclei.Conclusion The function of rat submandibular gland and gastric gland might be regulated by follicle stimulating hormone(FSH) through FSHR.
