Objective:To explore the effect of the developmental stages and quality on pregnancy outcome and birth outcome, and provide evidence for single blastocyst selection in frozen-thawed cycles.Methods:A retrospective cohort study analysis was performed on the data of patients with a total of 893 cycles who underwent single blastocyst transfer in frozen-thawed cycles in the Center for Reproductive Medicine, Qingyuan People's Hospital from January 2013 to June 2021. The cycles were divided into day 5 (D5) and day 6 (D6) groups according to the time of blastocyst formation. Then the two groups were divided into four subgroups according to the quality of blastocyst, namely, D5 good-quality embryo subgroup, D5 non-good-quality embryo subgroup, D6 good-quality embryo subgroup and D6 non-good-quality embryo subgroup. The general data, clinical outcomes and neonatal outcomes of each group were compared.Results:1) The clinical pregnancy rate [60.14% (332/552)], the implantation rate [60.14% (332/552)] and the live birth rate [47.64% (263/552)] in D5 group were significantly higher than those in D6 group [45.75% (156/341), 45.75% (156/341), 36.36% (124/341), all P<0.001], but there were no significant differences in body mass index, duration of infertility, intimal thickness of transplantation day and miscarriage rate between the two groups (all P>0.05). In addition, there were also no significant differences in birth weight, low birth weight rate, fetal macrosomia rate and male/female ratio (all P>0.05). 2) There were significant differences in clinical pregnancy rate [61.00% (294/482), 54.29% (38/70), 51.00% (127/249), 31.52% (29/92)] and live birth rate [48.96% (236/482), 38.57% (27/70), 41.37% (103/249), 22.83% (21/92)] among D5 good-quality embryo subgroup, D5 non-good-quality embryo subgroup, D6 good-quality embryo subgroup and D6 non-good-quality embryo subgroup (all P<0.001). D5 good-quality embryo subgroup had the highest clinical pregnancy rate and live birth rate, while D6 non-good-quality embryo subgroup had the lowest clinical pregnancy rate and live birth rate. There were also no significant differences in birth weight, fetal macrosomia rate and male/female ratio among the four subgroups (all P>0.05), while there was a significant difference in low birth weight rate [5.08% (12/236), 0 (0/27), 4.85% (5/103), 23.81% (5/21)] among the four subgroups ( P=0.014). 3) There were no significant differences in clinical pregnancy rate and live birth rate between D5 non-good-quality embryo subgroup and D6 good-quality embryo subgroup (all P>0.05). The clinical pregnancy rate and the live birth rate of 4BC in D5 were lower than those of 4AA, 4AB and 4BA in D6, while the miscarriage rate of 4BC in D5 was higher than that of 4AA, 4AB and 4BA in D6, but there were no significant differences (all P>0.05).The clinical pregnancy rate and the live birth rate of 4BC in D5 were higher than those of 4BB in D6, but there were no significant differences (all P>0.05). Conclusion:In the frozen-thawed cycle of single blastocyst transplantation, D5 good-quality blastocysts are preferred. When faced with D5 non-good-quality embryos and D6 good-quality embryos, the optimal choice was D6 4AA>D6 4BA>D6 4AB>D5 4BC>D6 4BB.

Liver cancer is one of the most common cancers in China. In recent years, liver cancer tends to be treated with comprehensive therapies, including surgery, ablation, interventional embolization, radiotherapy, chemotherapy, targeted therapy, immunotherapy, and liver transplantation. At present, the low surgical resectionrate is one of the main factors affecting the prognosis of liver cancer patients. Preoperative neoadjuvant therapy or conversion therapy for liver cancer can maximize the rate of surgical resection and improve the prognosis. With the rapid development of radiotherapy and immunotherapy in the comprehensive treatment of liver cancer, it has been gradually confirmed that the unique effects of preoperative radiotherapy and immune therapy for liver cancer can improve the prognosis of the patients. Therefore, this paper reviewed the research progress in the preoperative radiotherapy and immunotherapy for liver cancer by searching relevant literature and reports at home and abroad.

Objective:To investigate the significance and mechanism of ten-eleven translocation (Tet1) against Mycobacterium marinum ( Mm) infection in mice. Methods:SPF wild-type C57BL/6 and Tet1-knockout (Tet1KO) mice were injected intravenously with Mm. All mice were monitored and the abscesses formed in tail were observed and quantified. Pathological changes in mouse tail tissues were observed using hematoxylin and eosin (HE) staining and transmission electron microscopy and the differences between the two groups were analyzed. Immunohistochemistry staining was used to detect the expression and distribution of TNF-α and TGF-β in mouse tail tissues. Moreover, mouse tail tissues were cultured on 7H10 plates for bacterial counting. The expression of NF-κBp65 and TGF-β was detected by Western blot. Results:Obvious lesions including abscesses and ulcers were formed in the Mm-infected C57BL/6, but only scattered small abscesses were observed in Mm-infected Tet1KO mice. During Mm infection, the bacterial load was gradually increased in C57BL/6 mice, but decreased in Tet1KO mice. Histopathological examination showed that obvious inflammatory cell infiltration and typical granulomatous lesions were found in Mm-infected C57BL/6 mice, while no significant inflammatory cell infiltration was detected in Mm-infected Tet1KO mice. Immunohistochemistry staining demonstrated that the expression of TNF-α and TGF-β was lower in Mm-infected Tet1KO mice than in Mm-infected C57BL/6 mice. Moreover, the expression of phosphorylated NF-κBp65 and TGF-β was significantly reduced in Mm-infected Tet1KO mice as compared with that in Mm-infected C57BL/6 mice. Conclusions:Deletion of Tet1 could alleviate the inflammatory damage mediated by Mm and enhance the host immune response to bacteria.

AIM: To study the effect of ligustrazine on the cardiacmyocyte lesion in rats with type 2 diabetes mellitus.METHODS: Male Wistar rats were injected with STZ via tail vein under high-glucose and high-fat feeding for 4 weeks to establish the animal model of type 2 diabetes mellitus.Ligustrazine at different doses was used to treat the diabetic rats.The body weight, blood glucose and the morphology of heart tissues were observed.The myocardial levels of IL-1β, IL-6 and TNF-α were detected by ELISA, and the protein expression of IKKβ and NF-κB in the myocardium was determined by Westeren blotting.RESULTS: Ligustrazine at high dose alleviated the body weight reduction and blood glucose elevation cause by diabetes, and reduced pro-inflammatory factors IL-1β, TNF-α and IL-6.Moreover, the protein expression of IKKβ and NF-κB was significant decreased by ligustrazine.CONCLUSION: Ligustrazine inhibits the myocardial inflammation caused by diabetes through anti-inflammatory pathway.

Objective To compare the dosimetric difference among plans designed by 4-field,6-field TomoDirect and TomoHelical techniques in Tomotherapy system for left-breast cancer patients with radiotherapy after breast-conserving surgery.Method A total of 16 patients with left-breast cancer following breast-conserving surgery and intensity-modulated radiation therapy were enrolled in this retrospective study.The 4-field TomoDirect (TD4),6-field TomoDirect (TD6),and TomoHelical (TH) techniques were applied to design simulation plans in tomotherapy system for each patient,respectively.The differences of dose distribution and treatment parameters were analyzed in this study.Results Three plans all met the clinical requirement.Thereinto,TD4 was superior to TH in the dose limitation of organs at risk (OARs),especially the max dose of cord and right-breast,thc 5 Gy radiation volume of lung,and the mean dose of heart(F =595.60,129.24,60.44,65.37,P ＜ 0.05),but inferior to TH in dose homogeneity (HI) and conformity (CI) (F =2.78,60.93,P ＜ 0.05).However,TD6 improved TD4's HI and CI when delivered the lower OARs dose compared to TH.Meanwhile,the number of monitor units was less in TD technique and reduced the treatment times (F =24.89,3.75,P ＜ O.05).Conclusions For the radiotherapy of left-breast cancer patients after breast-conserving surgery,TD6 technique appeared to be superior,with the lower radiation dose of OARs compared to TH technique,and the better target's HI and CI in comparison with TD4 technique,especially in patients with early stage breast cancer.

Objective To investigate the effects of ovarian induction with raloxifene(RAL)versus clomi-phene citrate(CC)on the endometrial receptivity in mouse endometrium during perimplantation period. Methods 48 female Kun-ming mouse were randomly divided into four groups in equal number:RAL 240 mg group,RAL 180 mg group,CC group,natural conception group(NC),all treated with ovulation induction after drug administration.Successfully mated female mouse were killed,and uterus samples were collected for HE stain-ing and immunohistochemistry. Results HE staining showed that the endometrial morphology in the RAL 180 mg group and RAL 240 mg group and NC group were better than that of CC group.The expressions of COX-2 and LP-AR3 in the RAL 180 mg group and RAL 240 mg group were similar to NC group,without significant difference among the three groups(P > 0.05). But in the CC group,it was statistically significantly lower than other three groups(P<0.05),indicating ovarian induction with RAL did not decrease the expressions of COX-2 and LPAR3 in endometrium. Conclusion The mechanism of ovulation induction with RAL is similar to CC,but RAL has fewer adverse effects on the endometrial receptivity compared with CC.
