ABSTRACT
Objective:To investigate the effect of internet nursing model on female patients who are undergoing in vitro fertilization-embryo transfer, improve the quality of nursing service in reproductive center.Methods:A total of 201 female patients undergoing in vitro fertilization-embryo transfer from April 2018 to December 2018 were divided into the intervention group(102 cases) and the control group(99 cases) by random digits table method. The patients in intervention group were treated with nursing care based on the internet platform, and the control group was given routine care. The duration of intervention was from the patients determined treatment plan to the time pregnancy test 14 days after embryo transfer. The Self-rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS), Fertility Quality of Life(FertiQoL), and Connor-Davidson Resilience Scale(CD-RISC) were used to evaluate the differences in anxiety and depression, quality of life, and psychological resilience before and after intervention. The outcome of in vitro fertilization-embryo transfer was observed in two groups.Results:After intervention, the score of SAS, SDS were 26.03±6.43, 28.79±5.26 in the intervention group, and 40.76±6.81, 36.13±6.27 in the control group, the difference were significant( t values were -15.77, -9.00, all P<0.01). After intervention,the dimensional scores of mental and physical, social relationship, tolerance to treatment in the FertiQoL were 68.21±18.34, 75.56±19.58, 69.14±18.91 in the intervention group, and 58.11±17.42, 67.24±19.27, 58.77±19.86 in the control group, the difference were significant( t values were 4.00, 3.04, 3.79, all P<0.01). After intervention,the dimensional scores of tough, optimistic in CD-RISC were 37.03±10.51, 14.02±3.25 in the intervention group, and 26.73±9.81, 10.13±3.41 in the control group, the difference were significant( t values were 7.17, 8.28, all P<0.01). The average number of high-quality embryos and clinical pregnancy rate were 1.79(0.59, 4.51), 49.02%(50/102) in the intervention group, and 1.22(0.36, 2.86) , 33.33% (33/99) in the control group, the difference were significant ( t value was 2.47, χ2 value was 5.10, all P<0.05). Conclusions:The new nursing model based on internet has positive significance for the treatment of female patients undergoing in vitro fertilization-embryo transfer, which can improve patients' anxiety and depression, improve their quality of life and enhance their psychological resilience.
ABSTRACT
Objective To find the association between follicular output rate and clinical outcome in patients with polycystic ovarian syndrome (PCOS).Methods A total of 285 female patients with PCOS who were undergoing in vitro fertilization-embryo transfer (IVF-ET) for the first time were included in the study and were divided into three groups according to follicular output rate (FORT) values.The general information,the parameters of the controlled ovarian hyperstimulation,and clinical outcomes were compared.Results The concentration of serum E2 on the day of HCG,preovulatory follicle count (PFC),the number of retrieved oocytes,good-quality embryo rates,clinical pregnancy rate decreased sequently in groups with high,mediate and low FORT value.The incidence of moderate and severe ovarian hyper-stimulation syndrome (OHSS) in the group with mediate FORT value was significantly lower than that of groups with high and low FORT value.The incidence of severe OHSS in 3 groups with high,mediate and low FORT value was 20.6％,9％ and 17.8％ respectively and the difference was statistically significant (P =0.037).Conclusions The value of FORT may predict the clinical outcome of IVF/ ICSI-ET in patients with PCOS.Effort should be made to prevent OHSS in PCOS patients with high or low FORT value in their controlled ovarian hyperstimulation cycles.
ABSTRACT
Objective To treat hydrosalpinx by using interventional embolization of fallopian tube or laparoscopic salpingectomy before the performance of auxiliary reproductive technology,i.e.in vitro fertilization and embryo transplant (IVF-ET),and to compare the clinical effect,technical advantages and disadvamages between the two methods.Methods A total of 170 patients with tubal infertility who had received IVF-ET were selected,the clinical data were retrospectively analyzed.The patients were divided into three groups:(1) interventional embolization group (n=65),using interventional embolization for hydrosalpinx;(2) laparoscopic salpingectomy group (n=55),adopting laparoscopic salpingectomy for hydrosalpinx;and (3) control group (n=50):for these patients bilateral proximal fallopian tube obstruction was performed,and IVF-ET was directly carried out if the patient had no hydrosalpinx.Results No statistically significant differences in the used dosage of gonadotropin (Gn),E2 level on HCG-injection day,the number of follicles on HCG-injection day,the number of retrieved oocytes,the fertilization rate,cleavage rate,clinical pregnancy rate,abortion rate,and ectopic pregnancy rate existed between each other among the three groups (P＞0.05).The technical success rate in both interventional embolization group and laparoscopic salpingectomy group was 100％.No severe complications occurred.The interventional embolization procedure had some advantages,it could be completed at clinic room,the operation time was short,no anesthesia was needed,the medical cost was low,etc.Conclusion Interventional embolization of fallopian tube and laparoscopic resection are equally effective in treating hydrosalpinx before IVF-ET is conducted.Both methods can improve pregnancy outcome,but interventional embolization method is more simple,safe,economical and effective,which deserves to be the preferred method of treatment.
ABSTRACT
Objective To investigate the serum IL-33 level and its association with TH1,TH2,TH17 and Treg cells in patients with unexplained recurrent spontaneous abortion(URSA).Methods Forty-six URSA patients and 40 healthy controls were enrolled.The proportions of TH1,TH2,TH17 and Treg cells in peripheral blood samples were determined by flow cytometry,and serum IL-33 levels by ELISA.Results The levels of serum IL-33 in URSA patients were significantly lower than that in healthy controls.The proportions of TH2 and Treg cells in URSA patients were significantly lower than that in healthy controls (P ＜ 0.05),while the proportions of TH 1 and TH 17 cells in URSA patients were significantly higher than that in healthy controls.Serum IL-33 levels were negatively correlated with the proportions of TH 1 and TH17 cells,and positively with that of TH2 cells,while no correlation with Treg cells.Conclusion Serum IL-33 levels decrease significantly in URSA patients,and are correlated with the proportions of TH1,TH2 and TH17 cells,indicating that IL-33 may be associated with TH1,TH2 and TH17 cells in URSA patients.
ABSTRACT
Objective To investigate the inhibition of pathogenic viral gene expression in HPV6bE6-positive cell line by specific siRNA, which might have great potential for clinical use. Methods B16 cells were transfected with recombinant plasmid pcDNA3.1(+)-GFP/HPV6bE6, and the positive cell clones were selected by fluorescence protein observation and RT-PCR. Four specific siRNAs, none of which shares homology with exons of known human genes, were designed and synthesized to target HPV6bE6 mRNA. Quantitative real-time PCR was performed to measure the inhibition rates of target gene expression by comparing HPV6bE6 mRNA concentrations before siRNA transfection with those after transfection. The inhibition rates of target gene expression with different siRNA concentrations of 0.2 nmol/L, 1 nmol/L, 10 nmol/L, 50 nmol/L, 150 nmol/L and with different treatment time at 24 h, 48 h, 72 h and 96 h after transfection were measured respectively. Results More than 90% reduction of HPV6bE6 mRNA was observed following treatment with HPV6bE6-siRNA, and HPV-negative cells were apparently unaffected by HPV6bE6-siRNA. The decrease of HPV6bE6 mRNA was maximal at 24 h after siRNA treatment and sustained for at least 4 days. The minimal level of siRNA to efficiently silence the homogeneous target gene HPV6bE6 was 1 nmol/L. Conclusion HPV6bE6-siRNA can efficiently and specifically silence target genes and may be developed as a potential therapeutic approach for HPV infection.

ABSTRACT
AIM: To study the effects of cripto antisense oligodeoxynucleotide (ASODN) on telomerase activity in colon cancer LS-174T cells. METHODS: Colon cancer LS-174T cells were treated with cripto ASODN. The expression of cripto mRNA was studied using real-time PCR. The telomerase activity was detected by telomeric repeat amplification protocol enzyme-linked immunoabsordent assay (TRAP-ELISA). The growth of LS-174T cells was observed with soft agar. RESULTS: Cripto ASODN inhibited the growth of LS-174T cells in a dose-dependent manner in soft agar. Cripto ASODN decreased the telomerase activity in colon cancer LS-174T cells, and the effects of repression were time-and dose-dependent. CONCLUSION: Cripto may contribute to the activation of telomerase in colon cancer.
