Objective:To investigate the effect of atosiban on hemodynamic parameters of uterine arteries and clinical effect evaluation in patients with previous implantation failure undergoing frozen-thawed embryo transfer.Methods:A retrospective cohort study was conducted to analyze 298 cycles of FET in the Department of Reproductive Medicine of the Second Affiliated Hospital of Zhengzhou University from January 2021 to June 2023. Patients were categorized into atosiban group ( n=149) and control group ( n=149) according to whether administered atosiban or not. The related indicators and clinical outcomes were compared between the two groups. Hemodynamic parameters of the uterine arteries, including bilateral uterine artery peak systolic velocity/diastolic velocity (S/D), pulsatility index (PI), resistance index (RI), and serum levels of prostaglandin F2α (PGF2α) and oxytocin were compared before and after atosiban treatment. Univariate and multivariate logistic regression analysis were applied to assess the effect of atosiban on pregnancy outcomes. The effect of atosiban on live birth rate was analyzed by age stratification. Results:The implantation rate [51.92% (135/260)], the clinical pregnancy rate [67.11% (100/149)] and the live birth rate [59.06% (88/149)] in atosiban group were significantly higher than those in control group [41.13% (102/248), P=0.015; 51.01% (76/149), P=0.005; 40.27% (60/149), P=0.001]; and the early miscarriage rate [9.00% (9/100)] was lower than that of control group [19.74% (15/76), P=0.040]. Multivariate logistic regression analysis showed that atosiban was an independent influencing factor of live birth rate ( OR=2.236, 95% CI: 1.371-3.646, P=0.001). The post-treatment right uterine artery blood flow S/D [4.61 (4.00, 5.36)], PI [1.81 (1.58, 2.05)], RI [0.79 (0.75, 0.82)], and left uterine artery blood flow S/D [4.62 (3.83, 5.61)], PI (1.84±0.38), RI [0.79 (0.74, 0.82)] were all lower than those before treatment [right S/D 4.93 (4.06, 6.04), P<0.001; PI 1.93 (1.60, 2.17), P=0.001; RI 0.80 (0.76, 0.83), P<0.001; left S/D 5.05 (4.20, 6.32), P<0.001; PI 1.95±0.43, P<0.001; RI 0.81 (0.76, 0.84), P<0.001]. Besides, the levels of PGF2α [97.01 (85.15, 109.93) ng/L] and oxytocin [41.18 (37.16, 46.78) ng/L] after treatment in atosiban group were significantly lower than those before treatment [119.71 (108.85, 129.99) ng/L, P<0.001; 51.87 (46.44, 55.54) ng/L, P<0.001). Moreover, the endometrial peristalsis waves in atosiban group were significantly less after treatment [1.00 (0.00, 2.00) times/min] than before treatment [2.00 (1.00, 3.00) times/min], and the difference was statistically significant ( P<0.001). Conclusion:Atosiban can improve uterine artery blood flow and reduce endometrial peristalsis waves in women with previous implantation failure, which increases endometrial blood perfusion. Additionally, it can also reduce the levels of PGF2α and oxytocin, and optimize the pregnancy outcome of the frozen-thawed embryo transfer.

Objective:To investigate the effect of sanguinarine(SAG)on the intestinal epithelial barrier in septic rats and to explore the potential mechanism initially.Methods:Rats were divided into Sham group,CLP group,low-dose SAG group(L-SAG group),medium-dose SAG group(M-SAG group)and high-dose SAG group(H-SAG group)according to the random number table method,10 rats in each group.The rat model of sepsis was induced by cecum ligation puncture(CLP)method.HE staining was used to observe the pathological damage of intestinal epithelium.Serum DAO activity was detected by diamine oxidase(DAO)kit.Detec-tion of urinary lactose/mannitol(L/M)ratio by high performance liquid chromatography.Detection of serum TNF-α,IL-6 and IL-1β levels by ELISA.Protein expression levels in intestinal epithelial tissues were detected by Western blot.Results:The intestinal mucosa was intact and the intestinal villi were neatly arranged of rats in the Sham group;the intestinal mucosa of CLP group showed congestion and edema,inflammatory cell infiltration,irregular arrangement of intestinal villi,and enlarged villi gap;the pathological damage of intestinal mucosa in M-SAG group and H-SAG group were reduced to different degrees compared with the CLP group.Chiu's score,se-rum DAO activity and urinary L/M ratio were significantly higher in the CLP group compared with the Sham group;Chiu's score,se-rum DAO activity and urinary L/M ratio were significantly lower in the M-SAG and H-SAG groups compared with the CLP group(P<0.05).The serum TNF-α,IL-6 and IL-1β levels were significantly lower in the CLP group than in the Sham group,while the serum TNF-α,IL-6 and IL-1β levels were significantly higher in the M-SAG and H-SAG groups than in the CLP group(P<0.05).Claudin-3,ZO-1 and ocludin protein expressions were significantly lower in the intestinal epithelium of rats in the CLP group compared with the Sham group,while MLCK,MLC and p-MLC protein expressions were significantly increased.Compared with the CLP group,Claudin-3,ZO-1 and occludin protein expressions were significantly increased in the intestinal epithelium of rats in the M-SAG and H-SAG groups,while MLCK,MLC and p-MLC protein expressions were significantly decreased(P<0.05).Conclusion:SAG can reduce in-testinal barrier damage,inhibit intestinal barrier permeability,and protect intestinal barrier integrity in septic rats,which is at least partially achieved by inhibiting MLCK-MLC signaling pathway activation.

Probiotics are natural systems bridging synthetic biology, physical biotechnology, and immunology, initiating innate and adaptive anti-tumor immune activity. We previously constructed an all-in-one engineered food-grade probiotic Lactococcus lactis (FOLactis) which could boost the crosstalk among different immune cells such as dendritic cells (DCs), natural killer cells, and T cells. Herein, considering the limited clinical efficacy of naked personalized neoantigen peptide vaccines, we decorate FOLactis with tumor antigens by employing a Plug-and-Display system comprising membrane-inserted peptides. Intranodal injection of FOLactis coated with neoantigen peptides (Ag-FOLactis) induces robust DCs presentation and neoantigen-specific cellular immunity. Notably, Ag-FOLactis not only triggers a 45-fold rise in the quantity of locally reactive neoantigen-specific T cells but also induces epitope spreading in both subcutaneous and metastatic tumor-bearing models, leading to potent inhibition of tumor growth. These findings imply that Ag-FOLactis represents a powerful platform to rapidly and easily display antigens, facilitating the development of a bio-activated platform for personalized therapy.

Pulmonary complications， the most common postoperative complications of lung cancer， not only affect the quality of life of the patients after surgery but also increase the prognostic risks of postoperative recurrence and metastasis， threatening the life safety. At present， a multidisciplinary model of diagnosis and rehabilitation with integrated traditional Chinese medicine （TCM） and Western medicine has been initially formed under the guidance of the concept of rapid rehabilitation post operation for lung cancer. However， the treatment that only aims at shortening hospital stay and reducing the incidence of postoperative complications does not pay enough attention to the postoperative functional rehabilitation of the lung and the impact of follow-up adjuvant therapy， which affects the completeness of rehabilitation. This paper classifies the typical postoperative symptoms and manifestations of lung cancer into five groups： Lung system， emotion， digestive tract， pain， and nerve. On this basis， this paper summarizes the three core pathogeneses of postoperative complications of lung cancer as failure of Qi to ascend and descend leading to insecurity of defensive exterior， vessel block leading to Qi stagnation and fluid retention， and lung Qi deficiency leading to spleen and kidney deficiency. Accordingly， this paper proposes the treatment principle of protecting healthy Qi and treating Qi with the core of descending-tonifying-ascending-dispersing Qi and puts forward three treatment methods. The first is replenishing Qi and consolidating exterior， and expelling phlegm and regulating lung. The second is replenishing Qi and promoting blood flow to resolve stasis and relieving pain. The third is replenishing Qi and tonifying lung， and invigorating spleen and tonifying kidney. Furthermore， this paper elaborates on the pathogenesis and treatment principles of four common postoperative complications： Lung infection， pleural effusion， atelectasis， and bronchopleural fistula. On the basis of Western medical treatment， the TCM treatment characteristics of treating symptoms in the acute phase and eradicating the root cause in the chronic phase should be played. While dispelling the pathogen， measures should be taken to protect the healthy Qi， including tonifying lung Qi， regulating spleen Qi， and replenishing kidney Qi. This study summarizes the pathogenesis and treatment strategy of common postoperative complications of lung cancer according to the principle of protecting healthy Qi and treating Qi， aiming to provide guidance for the future treatment of postoperative complications of lung cancer.
