Preliminary study on the psychological status of male patients with infertility / 中国实用妇科与产科杂志

OBJECTIVE: To evaluate mental status of the infertile men and explore the risk factors for the mental disorders.METHODS: Men with perceived male infertility were divided into two groups(mild or severe)according to their severity of semen quality from Aug. 2015 to Feb. 2016 in Shengjing Hospital of China Medical University.Their mental health was assessed with the symptom check list(SCL-90).Multiple Logistic regression analysis was performed to identify risk factors of the mental disorders.RESULTS: The SCL-90 total score,somatization factor score,depression factor score,anxiety factor score and psychoticism factor score of the poor semen quality group were significantly higher than those of the group with better semen quality(P<0.05).RESULTS: of the Logistic regression analysis showed that the general risk factors for mental disorders in infertile men were irregular daily life,irregular meals,lack of regular exercise,recent experience of significant adverse events and poor semen quality.Among them,poor semen quality was the risk factor for the anxiety factor,while the risk factors for depression were irregular daily life,lack of regular exercise and recent experience of significant adverse events.CONCLUSION: Men with perceived male infertility tend to have more severe psychological disorders when their semen quality is poor.Men who do not have regular daily life,meals or exercise,or who have recently experienced significant adverse events or who have poorer semen quality are more prone to mental disorders.

Effects of bacterial lipopolysaccharide on the mineralization and differentiation of periodontal ligament stem cells / 医学研究生学报

Objective Periodontal tissue engineering has shown a highlight prospect in the treatment of periodontitis,but the related clinical experiments have not achieved the predetermined goal. In this study,we analyzed the reasons for the limited clinical efficacy of periodontal tissue engineering. Methods We primarily cultured the periodontal tissue from the young permanent teeth extracted for or-thodontic treatment,isolated periodontal ligament stem cells (PDLSCs),and transplanted the well-grown third-generation PDLSCs onto the fluorapatite-polycaprolactone (FA-PCL) nanofiber scaffolds and PCL nanofiber scaffolds. We randomly divided the cells into groups A (cultured with 10 ng/mL porphyromonas gingivalis lipopo-lysaccharide (Pg-LPS)+FA-PCL),B (cultured with 10 ng/mL PG-LPS+PCL),C (cultured with 10 μg/mL PG-LPS+FA-PCL),D (cultured with 10 μg/mL PG-LPS+PCL),E (cultured with FA-PCL),and F (cultured with PCL),and observed their proliferation,differentiation and mineralization. Results The PDLSCs adhered and grew well after transplanted onto the nanofiber scaffolds and their proliferation significantly increased in groups A and B but decreased in C and D as compared with E and F. At 7 days,the expres-sions of ALP and mineralization-related genes runx2 and SPP1 in the PDLSCs were significantly higher in group E than in the other five groups (P<0.05),but higher groups A and C than in B and D as well as in A than in C. At 28 days,alizarin red and Von Kossa stai-ning showed a higher positivity in group E than in the other five groups,but higher groups A and C than in B and D as well as in A than in C. Conclusion The inflammatory environment not only affects the proliferation of PDLSCs,but also inhibits their differentiation and mineralization. The FA-PCL scaffold can reduce the cytotoxic effect of PG-LPS.

Different methods for the diagnosis of endometrial histological comparative study / 中华妇产科杂志

Objective To evaluate the feasibility of endometrial sampler Pipelle for endometrial histologic diagnosis.Methods Using prospective and self-control methods,200 patients with endometrial biopsy firstly used Pipelle endometrial sampler for endometrial tissue,then followed by diagnostic curettage,the same pathologist evaluated the specimen quality and made the histologic diagnosis.Results Totally 200patients completed the observation,the specimen satisfaction of Pipelle was 93.0％ (in this 200 cases,186cases were satisfactory),its pathological accuracy was 85.0％ (in this 200 cases,170 cases' pathological results are highly consistent with diagnostic curettage).There was no significant difference between two kinds of endometrial sampling (P＞0.05).There was no pain for patients during the Pipelle using process.Conclusion Pipelle could obtain satisfactory samples used for histological diagnosis in normal endometrium,simple hyperplasia,complex hyperplasia,atypical hyperplasia and endometrial cancer disease,because its pathological accuracy is so close to the diagnostic curettage,which may be used as a routine screening tool of endometrial diseases.
