Angiographic uterine artery embolization followed by immediate curettage: an efficient treatment for controlling heavy bleeding and avoiding recurrent bleeding in cervical pregnancy

Two cases of cervical pregnancy with heavy bleeding successfully treated by uterine artery embolization (UAE) followed by immediate curettage are described in this report. Case 1 demonstrated intermittent bleeding after serious bleeding was successfully controlled by UAE. Serum beta human chorionic gonadotropin (beta-hCG) level rose remarkably after a short time decline. Transvaginal sonography consistently revealed a heterogeneous mass in the cervix. Repeated UAE followed by immediate curettage was performed and complete resolution was achieved. Case 2 was also successfully managed by UAE followed by immediate curettage after failure of medical treatment. This report suggests that UAE followed by immediate curettage is a safe and efficient procedure for controlling heavy bleeding and avoiding recurrent bleeding when fertility capacity is desired in cases of cervical pregnancy with fetal cardiac activity and high beta-hCG concentration.     

Myocardial mechanics and energetics in experimental iron-deficiency anemia.

The effect of iron-deficiency anemia on myocardial mechanics and energetics was studied in 10 anesthetized bealge puppies. Nine littermates served as controls. Left ventricular/body weight ratio was increased 14.2% (P less than 0.05) and cardiac index 36.5% (P less than 0.02) in the anemic puppies. Heart rate, mean systolic pressure, myocardial lactate extraction coefficient, and lactic dehydrogenase isozymes were similar in both groups. Contractile state measured in vivo (pressure-velocity curves) and in isolated muscles (isotonic force-velocity curves) was virtually identical in the littermate groups. Despite markedly increased coronary blood flow in the anemia animals, oxygen consumption per unit weight of myocardium was the same in both groups. Contractile element efficiency averaged 18.3% in 10 adult mongrel dogs studied in a similar fashion and was 27.1% and 39.8% in the normal puppies and anemic puppies, respectively. The oxygen cost of internal or force-generating work was similar among the three groups of dogs. It is concluded that the volume load produced by iron-deficiency anemia was associated with a normal contractile state, normal unit myocardial oxygen consumption, no evidence of chronic anaerobiosis, and a high contractile element efficiency, perhaps as a consequence of increased diastolic fiber stretch.

血清抑制素A在预测孕早期先兆流产孕妇妊娠结局中的应用

目的探讨抑制素A在预测孕早期先兆流产孕妇妊娠结局中的价值。方法选择孕6～13周稽留流产孕妇18例及B超检查示活胎的先兆流产孕妇27例（妊娠继续组17例和难免流产组10例）,同孕龄正常孕妇40例。采用ELISA法测定各组孕妇血清抑制素A水平。结果正常孕妇血清抑制素A在孕早期随孕龄增加而增加,孕10～11周达高峰,孕12～13周逐渐降低。难免流产组血清抑制素A水平明显低于妊娠继续组（P〈0.01）;当抑制素A〈0.3 MoM时可筛查出90%的难免流产,敏感性为90%,特异性为94.1%。结论孕早期血清抑制素A的检测有助于预测先兆流产孕妇不良妊娠结局,当血清抑制素A〈0.3 MoM时对预测难免流产有较高的敏感性和特异性。

Predictors of post coronary artery bypass grafting atrial fibrillation

Objective: To investigate the incidence and relative risk factors of post coronary artery bypass grafting(post-CABG) atrial fibrillation (AF). Methods: 312 patients with CABG were reviewed and divided into an AF group and a non-AF group. Statistical analysis was used to compare the data between the two groups and screen for risk factors of post-CABG AF. Results: 103/312(33.01%) patients developed post-CABG AF. Univariate analysis showed that patients in AF group compared with those in non-AF group were more likely to have advanced age (≥ 70 years), early postoperative withdrawal of β-blockers, hypertension, left atrial enlargement ( ≥40 mm), a history of AF, prolonged p-wave duration ( ≥ 120 ms) and increased number of grafts (≥3). Multivariate logistic regression analysis showed that advanced age (≥70 years), early postoperative withdrawal of β-blockers, hypertension, left atrial enlargement (≥40 mm) and a history of AF were highly related to post-CABG AF. Conclusion: The incidence of AF in patients following CABG was 33.01% in this study. Advanced age, early postoperative withdrawal of β-blockers,hypertension, left atrial enlargement and a history of AF were independent risk factors of post-CABG AF.     

Expansion of CD3+CD8+PD1+ T lymphocytes and TCR repertoire diversity predict clinical responses to adoptive cell therapy in advanced gastric cancer

The adoptive cell therapy (ACT) and delivery of ex vivo activated cellular products, such as dendritic cells (DCs), NK cells, and T cells, have shown promise for the treatment of gastric cancer (GC). However, it is unknown which cells can improve patient survival. This study was focused on the antitumour activity of a subset of these cellular products and their relationships with clinical outcomes. Nineteen patients were enrolled at the Capital Medical University Cancer Center, Beijing Shijitan Hospital, from June 1, 2013, to May 30, 2016. CD8⁺PD1⁺ T-cell sorting was carried out using flow cytometry, and the T-cell receptor (TCR) repertoire during ex vivo expansion for 15 days was analyzed by next-generation sequencing. After 15 days of culture, the number of CD8⁺ T cells had increased significantly, and the number of CD4⁺ T cells had increased correspondingly. After ex vivo expansion, CD8⁺ T cells exhibited significantly enhanced expression of PD-1, LAG-3, and TIM-3 but not 4-1BB. Survival analysis showed that patients with a pro/pre value of CD8⁺PD-1⁺ T cells >2.4 had significantly favorable overall survival (OS) (median OS time, 248 days versus 96 days, P=0.02) and progression-free survival (PFS) (median PFS time, 183 days vs. 77 days, P=0.002). The sorted CD8⁺PD-1⁺ T cells displayed enhanced antitumor activity and increased IFN-γ secretion after coculture with autologous tumor cell lines. TCR repertoire diversity was decreased after ex vivo expansion, which decreased the Shannon index and increased the clonality value. The prognosis of patients was significantly improved and was associated with the extent of CD8⁺PD-1⁺ T-cell expansion. In summary, this study showed that after ex vivo expansion for 15 days, CD8⁺PD-1⁺ T cells could be identified as tumor-reactive cells in patients treated for GC. Changing TCR species can predict the extent of CD3⁺CD8⁺PD1⁺ T-cell growth and the effect of ACT treatment.
