Objective:To analyse the clinical significance of selective single embryo transfer by time-lapse mo-nitoring(TLM)or conventional morphology assessment(CMA)in vitro fertilization/intracytoplasmic sperm in-jection and embryo transfer(IVF/ICSI-ET),and to initially explore the predictive value of Raman spectral analy-sis of embryo culture medium for clinical pregnancy rate.Methods:The study is a prospective randomized con-trolled clinical trial.We assigned 139 patients treated with IVF/ICSI-ET in Reproductive and Genetics Center of Suzhou Municipal Hospital from April 2019 to July 2020,which were randomly assigned to either the CMA or the TLM group.We performed selective single-embryo transfer(fresh cycle and FET)after selecting the optimal em-bryos with TLM or CMA respectively.If the patient's first embryo transfer was unsuccessful,a second one would be performed to compare the differences in the cumulative live birth rate of embryo transfer and other pregnancy outcomes between the two groups.Meanwhile,we collected 15 μl of embryo culture medium at day 3 after IVF/ISCI fertilization for Raman spectroscopy analysis.Results:There were no differences in cumulative live birth,cu-mulative clinical pregnancy,cumulative premature birth,cumulative early spontaneous abortion,cumulative ectopic pregnancy and LGA or SGA between TLM and CMA groups(P＞0.05).The Neonatal sex ratio in the TLM group was lower than that in the CMA group,but the difference was not significant(P＞0.05).Raman spectros-copy analysis of embryo culture medium predicted the clinical pregnancy rate with 67.21％accuracy.Conclu-sions:In young women with a good ovarian reserve,the advantage of using TLM to evaluate embryos is not obvi-ous,so we should remain vigilant that embryo selection based on morphokinetic parameters may affect the sex ratio.Raman spectroscopic analysis of embryo culture medium is not yet able to effectively predict the planting ability of embryos.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Background and purpose: Docetaxel plus prednisone chemotherapy can improve the patients' survival for castrate-resistant prostate cancer. Angiogenesis inhibitors can also inhibit the growth of tumor. The curative effect of combined treatment is still not clear. This study aimed to evaluate the efficacy of docetaxel plus prednisone combined with thalidomide in treating castrate-resistant prostate cancer (CRPC) patients with bone metastasis. Methods:A total number of 78 CRPC patients were selected in Fuzhou General Hospital from Dec. 2008 to Jun. 2015. Seventy-eight patients were divided into two groups: 40 patients in chemotherapy group (docetaxel plus prednisone) and 38 patients in combined treatment group (docetaxel plus prednisone combined with thalidomide). A total number of 78 subjects were evaluated by the effective rate, the remission rate of bone pain, the prostate specific antigen (PSA) progression-free surviv-al, the overall survival and adverse effect. Results: The response rate (65.79%) and the remission rate of bone pain (86.84%) in combined treatment group were both higher than those in chemotherapy group (40.00% and 60.00%, P<0.05). The PSA progression-free survival (4.13 months), progression-free survival (4.25 months) and the overall survival (18.06 months) in combined treatment group were all longer than those in chemotherapy group (3.54, 3.75 and 16.26 months). The PSA pro-gression-free survival was significantly longer in combined treatment group (P<0.05). There was no significant difference in the overall survival between two groups (P>0.05). The rates of adverse effects including peripheral neuritis and lethargy in combined treatment group (26.32% and 55.26%) were higher than those in chemotherapy group (5.00% and 17.50%, P<0.05). Conclusion: Thalidomide combined with docetaxel plus prednisone in CRPC patients with bone metastasis can prolong the PSA progression-free survival and overall survival. The adverse effects are mild. It may become a new choice of treatment for CRPC.

Background and objectiveIt has been proven that tumor necrosis factor receptor-associated factor 6 (TARF6) was a commonly ampliifed oncogene in lung cancer. However, the precise role of TARF6 protein in lung cancer has not been extensively investigated. hTis study analyzed the effects of TARF6 on the proliferation, apoptosis, cell cycle, migration, and invasion capability of lung cancer cell lines, as well as the potential molecular mechanisms involved.MethodsTo address the expression of TARF6 in lung cancer cells, four lung cancer cell lines (A549, H1650, SPC-A-1 and Calu-3) were assayed to determine the expression of TARF6 protein by Western blot and TARF6 mRNA via qRT-PCR. Moreover, siRNA targeting TARF6 was introduced into SPC-A-1 and Calu-3 cells. Nuclear factor-?B (NF-?B) DNA-binding activity, apoptosis rates, cell proliferation, cell cycle, migration, and invasion were determined by electrophoretic mobility shitf assay, lfow cytometry, MTS assay, lfow cytometry, scratch test, and transwell chamber assay, respectively. Western blot analysis was also performed to evalu-ate the expression of the following proteins through K63-ubiquitination: P65, CD24 and CXCR4. Whole-genome sequencing analysis was conducted using a second-generation sequencer in SPC-A-1 cells.Results TARF6 was highly up-expressed in SPC-A-1 and Calu-3 cell lines than the other two cells, which also showed K63-ubiquitinization in TARF6. However, consti-tutive activation of NF-?B was observed only in SPC-A-1 lung cancer cells. Downregulation of TARF6 suppressed the NF-κB activation, cell migration, and invasion but promoted the cell apoptosis of SPC-A-1 cells. Markedly decreased expression of CD24 and CXCR4 was observed in SPC-A-1 cells transfected by TARF6 siRNA. Nevertheless, TARF6 downregulation did not affect the proliferation and cell cycle of SPC-A-1 cells. Additionally, TARF6 regulation did not affect the proliferation, apoptosis, cell cycle, migration, and invasion of Calu-3 cells. No mutations and no changes in gene copy numbers of TARF6 were found by whole-exome sequencing of SPC-A-1 cells.ConclusionTARF6 may be involved in cell migration, invasion, and apoptosis of SPC-A-1 cells, possibly through regulating the NF-?B-CD24/CXCR4 pathway.
