Objective To investigate the clinical values of next-generation sequencing (NGS) technology in diagnosis of miscarried chorionic villi genetic disorders. Methods Patients who underwent miscarriage (n=87) were enrolled in this study. Among all patients, 32 cases were of recurrent miscarrage and 55 cases were of sporadic miscarriage. In all collected patients, 35 women were 35 years or older while other 52 women were less than 35 years old. Positive detection rate and the abnormal detection rate were compared between these two methods. Chromosomes abnormal rates were also compared among different types of miscarrage and different ages. All aborted villi tissue were analyzed by NGS of whole genome and G-band?ing karyotype. Results The successful detection rate of chorionic villi by NGS (100.00%) was higher than that of G-band?ing karyotype (74.71%), and the detection rate of abnormal chorionic villi by NGS (58.62%) was also higher than that of G-banding karyotype (50.77%). Three cases of chromosome structure anomaly were found in those 51 chromosome anomalies (5.88%). Other 48 cases of chromosome anomalies were aneuploidy anomalies (94.12%) include 39 cases of trisomy, 2 cases of double trisomy and 1 case of triple trisomy and 6 cases of monomer. On the other hand, 32 cases of chromosome aneuploi?dy anomalies were found in 33 chromosome anomalies by G-banding karyotype, which include 24 cases of trisomy, 2 cases of double trisomy, 1 case of triple trisomy, 5 cases of monomer and 1 case of chromosome structure anomaly. Most NGS re?sults (n=64) were in agreement with G-banding karyotype but with 1 case of discrepancy. Chromosomal abnormality rate de?tected by NGS in sporadic miscarrage group and recurrent spontaneous miscarrage group were 60.00%and 56.25%respective?ly. There was no significant difference (P>0.05). Chromosomal abnormality rate picked by NGS in women aged≥35 years old (71.43%) was higher than that in women<35 years old (50.00%) with statistically significant difference (P<0.05). Conclu?sion NGS technology showed highly accuracy in detecting chromosomal abnomality from villi tissue. Therefore, it could help to detect genetic disorders of miscarrage. It is useful to determine the reasons of miscarrage and guide the next pregnancy.

Objective:To investigate the effective method to avoid the ovarian hyperstimulation syndrome(OHSS)in infertile patients underwent in vitro fertilization-embryo transfer(IVF-ET)and whole embryo freezing and thawing 2-3 cycles after egg retrieval.Methods:The controlled ovarian hyperstimulation(COH),the number of retrieved oocytes,the number of embryo freezing,and clinical pregnancy rate were compared between 239 patients with the ET cycle(group A)and 164 patients with whole embryo freezing and thawing(group B).Results:The levels of initial dosage of gonadotropins(Gn)and total dosage of Gn were higher in group A compared with those of group B(P ＜ 0.01).The level of estradiol(E2)on day of human chorinonic gonadotrophin(hCG),the number of retrieved oocytes and the number of embryo freezing were lower in group A compared with those of group B(P＜ 0.01).There were no differences in patient age,COH,rate of OHSS and clinical pregnancy rate between group A and group B.Conclusion:Freezing the whole embryos and thawing ET 2-3 cycles after egg retrieval didn't influence the treatment results in infertile patients.

Objective To build the index about the training effect of oncology specialist nurse and test the reliability and validity.Methods By consulting literature and the methods of Delphi,which was consulted by the 9 experts and the two rounds of 35 experts,the original index was estabhshed.The correlation coefficient and validity of the index was evaluated.Results A total of the index was consist of 106 first-l,second-land third-llevel items.Questionnaire recovery rate was 100％ (35/35).The level of authority was 0.816.Expert opinion concentration in various purposes mean variation coefficient was less than 0.244 2.The coordination level of expertise was 0.302.The overall reliability Cronbach α was 0.963.Adopting the method of double variable Spearman calculated the correlation coefficient was above 0.428.Cronbach a of second-and third-level indexes were 0.512-0.895.The second-land third-level indexes correlation coefficient were 0.428-0.931.Conclusions The index about the training effect of oncology specialist nurse has the high authority and representative.The reliability and validity of the index are better,which can be used to evaluate the efficacy of the evaluation about the training of oncology specialist nurse.

To explore the biological effects of light on trabecular cells, cultured bovine trabecular cells were exposed to visible light of different wavelength with different energy. Cellular morphology, structure, proliferation, and phagocytosis were observed. The cells showed no remarkable changes when the energy was low. When the exposure energy reached 1.12 mW/cm2, the cytoplasm showed a rough appearance, and cell proliferation and phagocytosis decreased. This phototoxicity was strong with white light (compound chromatic light), moderate with violet light or yellow light, and mild with red light.
