BACKGROUND:Insulin-like growth factor-1(IGF-1), a main active factor in growth hormone (GH), plays various biological functions, such as improving cognitive ability and anti-apoptotic action.
OBJECTIVE:To detect the expressions of GH and IGF-1 in the temporal cortex of Lewis dwarf rats, and to explore the effect of different concentrations of GH on the differentiation of hippocampal nerve stem cels (NSCs).
METHODS:Lewis dwarf rats aged 11(adult) and 20 (senile) month olds and normal wild-type rats were euthanized by decapitation, underwent the craniotomy quickly, and the temporal cortex in the cold saline was extracted. GH and IGF-1 levels were detected using western blotting. After isolation, purification and identification of the rat hippocampal NSCs, the effect of GH in different concentrations (10, 30, 90μg/L) on the NSCs differentiation was determined at 96 hours after culture.
RESULTS AND CONCLUSION:The GH level in the temporal cortex did not differ significantly among rats (P > 0.05). While the IGF-I level in the temporal cortex of Lewis dwarf rats was significantly higher than that of the wild-type rats (P < 0.05). The GH level in the temporal cortex of adult female Lewis dwarf rats was significantly lower than that of the male rats (P < 0.05). Immunofluorescence showed that the proportion ofβ III-tubulin-positive neurons was significantly higher than that in the control group (P < 0.05) after the hippocampal NSCs and precursor cels cultured for 96 hours with GH (30μg/L), but there was no significant difference between the control group and treatment group with GH of 10 or 90μg/L. These results suggest that GH and IGF-I are expressed in the temporal cortex of both Lewis dwarf and wild-type rats which are independent from pituitary GH and the peripheral circulating IGF-1. Additionaly, GH can promote the differentiation of hippocampal NSCs and precursor cels into neurons.

Objective: To investigate the current status and influencing factors of sleep disorders among pregnant women, so as to provide insights into health management during pregnancy. Methods: Pregnant women who underwent prenatal checkups at Hangzhou Obstetrics and Gynecology Hospital from January to October 2023 were selected as subjects, and general data including age, pregnancy period and exercise were collected through questionnaire surveys. Sleep quality, pregnancy stress, anxiety and depression were evaluated using Pittsburgh Sleep Quality Index, Pregnancy Stress Rating Scale, Pregnancy-related Anxiety Scale and Edinburgh Postnatal Depression Scale, respectively. Factors affecting sleep disorders among pregnant women were analyzed using a multivariable logistic regression model. Results: A total of 386 pregnant women was surveyed, with a mean age of (30.28±4.65) years, including 20.47% in the first trimester, 47.93% in the second trimester and 31.61% in the third trimester. Women with anxiety and depression accounted for 14.51% and 21.76%, respectively. Pregnancy stress was mainly moderate, accounting for 51.04%. There were 106 pregnant women with sleep disorders, accounting for 27.46%. Mutivariable logistic regression analysis showed that age (≥35 years, OR=1.656, 95%CI: 1.094-2.503), pregnancy period (third pregnancy, OR=2.097, 95%CI: 1.213-3.621), regular exercise in the past 6 months (OR=0.376, 95%CI: 0.210-0.670), anxiety (OR=2.794, 95%CI: 1.545-5.048), depression (OR=3.501, 95%CI: 1.877-6.529) and pregnancy stress (moderate, OR=1.355, 95%CI: 1.018-1.801; severe, OR=2.538, 95%CI: 1.417-4.540) were the factors affecting sleep disorders among pregnant women. Conclusions Sleep disorders of pregnant women is influenced by age, pregnancy period, pregnancy stress, anxiety, depression and exercise. It is necessary to identify high-risk individuals with sleep disorders early, and to provide psychological intervention and prenatal health guidance.

Objective To investigate the changes of serum gastrin level in patients with colon cancer and the relationship between serum gastrin level and colon cancer occurrence and development.Methods Data of 35 patients underwent colon cancer surgery from January 2010 to January 2012 in our hospital were collected,at the same time data of 28 patients with colonic polyps and 30 cases of normal were collected as normal control.Serum gastrin levels were tested by radioimmunoassay in patients with colon cancer before surgery,1,3,7 d after surgery and they were analyzed.Results The serum gastrin level of patients with colon cancer was significantly increased compared with colon polyps and healthy controls((92.45 ± 12.98) ng/L vs (49.66 ±10.34) ng/L vs (30.12 ±6.39) ng/L;F =9.455,P ＜0.001)).Serum gastrin level in patients with obstructive colon cancer was significantly higher than that in non-obstructive cancer((129.84 ± 15.32) ng/L vs (75.34 ±11.45) ng/L,t =12.181,P ＜0.001) ;Serum gastrin levels in patients who cut off colon tumor was signifcanfly lower than before surgery((43.02 ±8.34) ng/L,(40.74 ±6.78) rig/L,(38.12 ±7.09) ng/L vs (89.45 ±12.98) ng/L;P ＜0.05).But no significant change of serum gastrin levels in patients with the colon tumor compared with the preoperative((97.34 +8.30) ng/L vs (95.82 ±7.20) ng/L vs (94.44 ±7.74) ng/L vs (100.23 ± 10.82) ng/L; P ＞ 0.05).But there was significant difference on serum gastrin levels between patients who cut off colon tumor and patients with the colon tumor(within groups:F =8.341,P =0.012 ;between groups:F =7.871,P =0.024).Conchusion Serum gastrin levels in patients with colon cancer were significantly higher than that of patients with colon polyps and normal controls.There was also a significant reduction of serum gastrin in tumor resection,and therefore gastrin may be involved in the development of colon cancer.

Objective To investigate the effect of metformin on the growth of human anaplastic thyroid cancer cell HTh74Rdox which is doxorubicin resistant. Methods The HTh74Rdox was treated with different concentrations of metformin for 48 h. Cell morphology was observed by microscope, cell viability was tested by methylthiazoletetrazolium (MTT), cell apoptosis by annexin Ⅴ and propidium iodide double staining, the anti-oncogenic miRNA was assayed by realtime fluorescence quantitative PCR (RT-PCR), and the adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signaling pathway tested by western blot. Furthermore, the anti-oncogenic miRNAs were knockdown by miRNA inhibitors (miR-34a, miR-101, miR-125b, and miR-138 inhibitors) and the cells were treated by metformin for 48 h, after that, cell apoptosis was detected by annexin Ⅴ and propidium iodide double staining, the expression of protein related to AMPK/mTOR signaling pathway was detected by western blot. Results Metformin inhibited the growth of human anaplastic thyroid cancer cell HTh74Rdox in a concentration-dependent manner, the cell apoptosis was induced by metformin, and there was a significantly lower expression of miR-34a, miR-101, miR-125b, and miR-138 in the HTh74Rdox. However, the four above miRNAs were upregulated by metformin, and AMPK/mTOR pathway was also activated by metformin. When these miRNAs were suppressed by miR-inhibitors (miR-34a, miR-101, miR-125b, miR-138 inhibitors), the stimulating effect of apoptosis and AMPK/mTOR pathway by metformin were reversed. Conclusion Metformin significantly suppresses cell viability of human anaplastic thyroid cancer cell HTh74Rdox, and stimulates AMPK/mTOR pathway and apoptosis by upregulating the expressions of miR-34a, miR-101, miR-125b, miR-138 in HTh74Rdox cell.
