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.

Aiming at status of training the rural order directed free medical educational talents, we should improve the understanding of training the free medical students, perfect the relevant management system, strengthen medical ethics education of students, pay attention to humanistic care of students,strengthen the continuing education of students, standardize the access system of students, reform the medical distribution system, to ensure the quality of training free medical students.

A total of 120 patients with Ⅲ/Ⅳ degree hemorrhoids were randomly divided into 3 groups.Self-made drainage(A group),traditional device(B group)and stuffing(C group) were used at the end of operation.The patient postoperative complications and satisfaction were observed and compared.The results showed that postoperative abdominal distension,pain,medical dressing dampness and satisfaction were better in A group than those in B and C groups(all P ＜0.01).Postoperative abdominal distention in B group was lighter than that in C group and medical dressing dampness less in C group than that in B group (all P ＜ 0.01).Thus the self-made drainage device may reduce the levels of postoperative abdominal distension,pain and medical dressing dampness and increase postoperative patient satisfaction.

Objective To explore the clinical diagnosis and treatment of cyclic vomiting syndrome in children.Methods Thirty children proved with cyclic vomiting syndrome admitted from January,1998 to January,2003 were analyzed retrospectively.Results Cyclic vomiting syndrome was most likely to occur in 3-12 years old.The male to female ratio was 3∶2.The clinical manifestations were recurrent vomiting.Twenty-one cases had inducements,while 9 cases had not inducements.It was safe and efficient that curing cyclic vomiting syndrome with cyprohetadine and amitriptyline.Conclusions If these children with cyclic vomiting syndrome are inefficient to treatment,excluding metabolizable diseases,gastrointestinal,neurological diseases,they may be diagnosed cyclic vomiting syndrome,and cured with cyprohetadine and amitriptyline.
