PurposeTo compare the pregnancy outcome of emergency cerclage performed in twin and singleton pregnancies.MethodsA retrospective trial was carried out in the Department of Obstetrics and Gynecology, Sir Run Run Shaw Hospital in Zhejiang, China, from January 2013 to December 2018. A total of 89 women with acute cervical incompetence underwent the emergency cerclage. Main outcome measures were gestational age at delivery and the fetal outcome.ResultsThere were 31 twin and 58 singleton pregnancies that underwent emergency cerclage. In singleton pregnancies, gestational age at delivery (31.57 ± 6.11 vs 28.81 ± 4.34, p = 0.016), and prolongation of pregnancy (8.69 ± 6.13 vs 5.41 ± 3.72, p < 0.001) were greater, and the preterm delivery rate before 34 weeks was lower (53.4% vs 80.6%, p = 0.011) compared with twin pregnancies. Fetal weight was greater in singletons than in twins (2377.3 ± 862.1 vs 1630.3 ± 557.6, p < 0.001), but the fetal survival rate was similar. The proportion of twin gestations was significantly higher in the group with preterm delivery before 34 weeks (44.6% vs 18.2%, p = 0.011) and the proportion of previous term delivery was higher in the group with delivery at or after 34 weeks (30.3% vs 12.5%, p = 0.039). The group with preterm delivery before 34 weeks had a significantly larger size of visible membranes at cerclage than the group with delivery at or after 34 weeks (2.23 ± 0.86 vs 1.64 ± 0.80, p = 0.001). In binary logistic regression analysis, twin gestations and a larger size of visible membranes were associated with an increased risk of preterm delivery.ConclusionThe pregnancy outcome of emergency cerclage appears to have a better prognosis in singleton pregnancies than in twin pregnancies, and twin pregnancy is a risk factor for preterm delivery.

PurposeTo compare the pregnancy outcome of the modified transvaginal cerclage performed preconception and during pregnancy.MethodsA retrospective trial was carried out in the Department of Obstetrics and Gynecology, Sir Run Run Shaw Hospital in Zhejiang, China. A total of 604 women with cervical incompetence underwent the cerclage, and the time of the operation was decided by the patients or depended on when the patient presented. Main outcome measures were the gestational age and the fetal outcome.ResultsAfter the cerclage, the mean gestational age at delivery and the term delivery rate were significantly higher in history-indicated conception cerclage compared to preconception cerclage (36.8 ± 3.7 vs 35.8 ± 4.7, p < 0.01; 76.1 vs 66.9%, p < 0.05). The mean gestational age at delivery and the term delivery rate were significantly higher in ultrasound-indicated compared to physical examination-indicated conception cerclage (35.0 ± 5.7 vs 31.0 ± 5.5, p < 0.01; 63.2 vs 23.3%, p < 0.001). The fetal survival rate had no difference in these two comparisons, respectively.ConclusionsThe modified transvaginal cervicoisthmic cerclage is a promising and safe technique to improve obstetric outcomes in women with cervical incompetence in different cerclage indications, and history-indicated conception cerclage appears to have better pregnancy outcome.

PurposeThe purpose of this study is to determine whether intrauterine infusion of autologous platelet-rich plasma (PRP) gel increases endometrial thickness (EMT) and improves the outcomes of frozen-thawed embryo transfer (FET) in women with thin endometrium.MethodsThis study included 111 women (aged 25–44 years) who had thin endometrium. All patients had at least one previous cycle canceled because of thin endometrium or previous embryo transfer cycles and an EMT < 7 mm. Forty-seven women underwent intrauterine infusion of autologous PRP gel on three occasions during endometrial preparation and the remaining women served as controls. The final EMT was measured by ultrasound before the start of the luteal phase, and FET-related outcome parameters were monitored.ResultsMean EMT was greater in women who received PRP gel than in those who did not (6.7 mm vs. 6.3 mm, respectively, p < 0.05). FET was attempted in all women. The 47 women who underwent infusion of PRP had a significantly higher pregnancy rate (18 pregnancies (38.3%), with 17 (36.2%) ongoing) compared with 64 control women (ten pregnancies (18.5%), nine (16.7%) ongoing). However, there was no significant reduction in the miscarriage rate.ConclusionIntrauterine infusion of autologous PRP gel during endometrial preparation for FET cycles can improve the EMT, clinical pregnancy rate, and ongoing pregnancy rate in women with thin endometrium.

Mikania micrantha is one of the top 100 worst invasive species that can cause serious damage to natural ecosystems and substantial economic losses. Here, we present its 1.79 Gb chromosome-scale reference genome. Half of the genome is composed of long terminal repeat retrotransposons, 80% of which have been derived from a significant expansion in the past one million years. We identify a whole genome duplication event and recent segmental duplications, which may be responsible for its rapid environmental adaptation. Additionally, we show that M. micrantha achieves higher photosynthetic capacity by CO 2 absorption at night to supplement the carbon fixation during the day, as well as enhanced stem photosynthesis efficiency. Furthermore, the metabolites of M. micrantha can increase the availability of nitrogen by enriching the microbes that participate in nitrogen cycling pathways. These findings collectively provide insights into the rapid growth and invasive adaptation. Mikania micrantha is an extremely fast-growing invasive plant species that can cause serious damage to natural ecosystems. Here, the authors assemble its chromosome-scale reference genome and explore possible mechanisms that contribute to its rapid growth.

The programmed cell death protein 1 (PD-1) is an inhibitory receptor on T cells and plays an important role in promoting cancer immune evasion. While ubiquitin E3 ligases regulating PD-1 stability have been reported, deubiquitinases governing PD-1 homeostasis to modulate tumor immunotherapy remain unknown. Here, we identify the ubiquitin-specific protease 5 (USP5) as a bona fide deubiquitinase for PD-1. Mechanistically, USP5 interacts with PD-1, leading to deubiquitination and stabilization of PD-1. Moreover, extracellular signal-regulated kinase (ERK) phosphorylates PD-1 at Thr234 and promotes PD-1 interaction with USP5. Conditional knockout of Usp5 in T cells increases the production of effector cytokines and retards tumor growth in mice. USP5 inhibition in combination with Trametinib or anti-CTLA-4 has an additive effect on suppressing tumor growth in mice. Together, this study describes a molecular mechanism of ERK/USP5-mediated regulation of PD-1 and identifies potential combinatorial therapeutic strategies for enhancing anti-tumor efficacy. Ubiquitination and deubiquitination processes regulate the stability of PD-1, affecting T cell biology. Here the authors identify the ubiquitin-specific protease 5 (USP5) as a deubiquitinase for PD-1 and show that USP5 inhibition in combination with a MEK inhibitor or anti-CTLA-4 could promote anti-tumor immune responses in preclinical models.

Background  Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide, and is characterized by insidious onset, rapid progression, and poor prognosis. Immunotherapy is a first-line treatment for advanced HCC. The identification of immune-related prognostic markers may be an effective strategy to predict and improve clinical response rate of immunotherapy. Methods  The DESeq2, edgeR, and limma R packages were used to compare the transcriptomes of HCC with different prognoses. Cancer-related databases such as UALCAN, TNMplot, GEPIA, muttarget and Human Protein Atlas (HPA), and the Kaplan–Meier Plotter platform were used to analyze the relationship between CLDN18 and the clinical characteristics, as well as prognosis of HCC. The co-expressed genes of CLDN18 were obtained from LinkedOmics platform, and GO functional enrichment and KEGG pathway analysis were performed. The CIBERSORT, TIMER, Timer 2.0 and TISIDB algorithms were used to analyze immune infiltration. Results  CLDN18 was differentially expressed in HCC patients with different prognoses, and its expression level in PBMC was positively correlated with the stage of BCLC. In addition, CLDN18 was significantly overexpressed in HCC tumor tissues compared to adjacent non-tumor tissues, which was consistent with PBMC sequencing results and immunohistochemical data from human protein profiles. CLDN18 was also positively correlated with HCC staging and grading, and high expression levels of CLDN18 predicted shorter overall survival. Functional annotation of CLDN18 in HCC revealed enrichment of the cellular senescence and protein activation cascade, along with biological processes such as cell cycle, inflammatory response, and cellular ketone metabolism. In addition, CLDN18 was also associated with tumor infiltrating immune cells, suppressive immune cell markers, T lymphocyte depletion and activation of HCC, and low expression of CLDN18 was associated with higher CD8 + T cell infiltration and better survival rates. Conclusions CLDN18 is a potential prognostic marker and immunotherapeutic target for HCC.

Marchiafava-Bignami disease (MBD) is a metabolic disease of the nervous system. It mainly involves the Corpus callosum, but the handknob area is rarely involved. This article reports a MBD case involving the bilateral handknob area. The involvement of the bilateral handknob area contributes to the clinical presentation of convulsions of both hands. Through this case, more clinicians realize the bilateral handknob area involvement in MBD, which is helpful for the identification and diagnosis of MBD. To our knowledge, this is the first report on MBD involving the bilateral handknob area.

Hepatocellular carcinoma (HCC) is a lethal malignancy. Although considerable efforts have been made in recent years regarding treatments, effective therapeutic drugs for HCC remain insufficient. In the present study, polyphyllin VI was identified as a potential therapeutic drug for HCC by screening natural herbal compounds. The therapeutic effects of polyphyllin VI were assessed using Cell Counting Kit-8, lactate dehydrogenase release and colony formation assays. The occurrence of ferroptosis was determined by assessing lipid peroxidation by reactive oxygen species, malondialdehyde levels, intracellular ferrous iron levels, and the mRNA and protein levels of glutathione peroxidase 4 (GPX4). The migratory and invasive abilities of HCC cells were examined using wound healing and Transwell assays. The results revealed that polyphyllin VI inhibited the proliferation, invasion and metastasis of HCC cells (HCCLM3 and Huh7 cells) by inducing ferroptosis. In addition, through a network pharmacology-based approach and molecular docking analyses, it was found that polyphyllin VI may target the signal transducer and activator of transcription 3 (STAT3). HCC cells were treated with polyphyllin VI or a STAT3 inhibitor (Stattic), both of which exerted similar inhibitory effects on protein expression. Furthermore, immunofluorescence staining revealed that polyphyllin VI significantly inhibited the nuclear translocation of p-STAT3 in HCC cells. Mechanistically, by the overexpression of STAT3, it was confirmed that STAT3 binds to GPX4 and promotes its protein expression and transcription, whereas polyphyllin VI induces ferroptosis by inhibiting the STAT3/GPX4 axis. Subsequently, in vivo experiments revealed that polyphyllin VI inhibited the growth of subcutaneously transplanted tumors. On the whole, findings of the present study suggest that polyphyllin VI inhibits STAT3 phosphorylation, which inhibits GPX4 expression and induces the ferroptosis of HCC cells, eventually inhibiting their invasion and metastasis. These data suggest that polyphyllin VI may be a candidate for the prevention and treatment of HCC.
