Objective: To explore the therapeutic efficacy and mechanism of transcutaneous electrical acupoint stimulation (TEAS) for menopausal insomnia. Methods: A total of 80 patients with menopausal insomnia were randomly divided into a control group and an observation group, with 40 cases in each group. The patients in the control group received conventional Western medication treatment, and the patients in the observation group received TEAS on the basis of conventional Western medication treatment. The treatment for both groups lasted for 4 weeks. Before and after treatment, Pittsburgh sleep quality index (PSQI) and modified Kupperman scale were evaluated, and the serum levels of estradiol (E2) and follicular stimulating hormone (FSH) were measured. The therapeutic efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05); in the control group, the improvement of PSQI score was significant (P<0.05), while the change of modified Kupperman score was insignificant (P>0.05); the PSQI and Kupperman scores in the observation group were significantly improved after treatment (both P<0.05), and there were significant differences between the observation group and the control group in PSQI and Kupperman scores (both P<0.05). After treatment, the serum E2 and FSH levels in the control group were not statistically different from those before treatment (both P>0.05); the serum E2 level was significantly increased (P<0.05), and the FSH level was decreased (P<0.05) in the observation group after treatment, and the between- group differences in serum levels of E2 and FSH were significant (both P<0.05).Conclusion: TEAS plus conventional Western medication in treating menopausal insomnia is effective, and can significantly improve the symptoms of insomnia and menopause, which may be related to the regulation of serum E2 and FSH levels.

BACKGROUND: Zein has excel ent solubility, heat resistance and biodegradability, but its biocompatibility and effect on periodontal defects repair are under discussion. OBJECTIVE: To analyze biocompatibility of zein and its effect on periodontal defect repair. METHODS: Zein scaffold was prepared by solvent casting/particulate leaching. In vitro test: Human periodontal ligament cel s were co-cultured with zein scaffold for 18 days, and cel growth was observed by scanning electron microscope. In vivo test: Eight Beagle dogs were enrol ed to establish periodontal defect models, which were randomly assigned to receive zein scaffold implantation as experimental group, or interrupted suture as control group. Afterwards, the defect region was observed by scanning electron microscope at 3 months. RESULTS AND CONCLUSION: In vitro results: Human periodontal ligament cel s adhered wel and tightly on the scaffold with a fusiform, and could grow around pores. In vivo results: In the experimental group the scaffold dissolved completely, bone trabecular arranged regularly, and mature tissues appeared, to be integrated with the surrounding tissues; in the control group, the defect region almost healed, but there were irregular fibers and obvious lacunae. Moreover, compared with the control group, the height of new alveolar bone and bone defect, as wel as the length of junctional epithelium were significantly decreased, and new cementum was significantly increased in the experimental group (P < 0.05). To conclude, zein scaffold has good biocompatibility and can promote periodontal defect repair.

Objective To enrich pancreatic cancer stem cells through culturing mammospheres, and to detect the expressions of epidermal growth factor receptor(EGFR) and a disintegrin and metalloprotease 9 (ADAM9) and investigate their significance. Methods PANC1 cells were cultured in serum-free conditioned medium to continuously generate mammospheres, and parts of mammospheres were cultured on a collagen substratum to induce differentiation. Mammospheres cells and differentiated cells were collected, flow cytometry was used to detect the proportion of side population (SP) cells, and the expressions of EGFR, ADAM9 mRNA and protein were detected by real-time PCR and Western blotting. Results PANC1 cells mammospheres were successfully generated and could be passed continuously. After differentiation, mammospheres cells could regain the ability of adherent growth. The proportion SP cells in mammospheres cells and differentiated cells were ( 5.40 ± 0.38 ) % and (2.80 ± 0.42 ) %, and the difference was statistically significant ( P ＜ 0. 05 ).Compared with differentiated cells, the expression of EGFR and ADAM9 mRNA of mammospheres cells upregulated 2.5 and 3.0 folds ( P ＜ 0. 05 ). The expressions of EGFR and ADAM9 protein of mammospheres cells were 0.90 ± 0. 09 and 0.64 ± 0.07, which were significantly higher than those in differentiated cells (0.62 ±0.11 and 0.48 ±0.09, P ＜0.05). Conclusions Mammosphere cells contained higher proportion of pancreatic cancer stem cells. ADAM 9 may play an important role in the occurrence and development of pancreatic cancer through the EGFR signaling pathway.
