Objective The current study aims to explore the establishment of the patient-derived tumor xenograft (PDTX) model. Materials and Methods Twenty patients with gastric cancer, 10 males and 10 females, were enrolled in the current study. Firstly, the volume, invasion and metastasis of the xenografts were observed. Subsequently, the correlation between tumor tissues of the PDTX mouse model and the patients' primary tumor tissues was evaluated by pathological H&E staining and immunohistochemistry. Results The results showed that the PDTX models corresponding to 15 of the 20 patients were successfully established, and the success rate of PDTX model establishment was 75%. Furthermore, the PDTX models maintained the differentiation degree, morphological characteristics and structural characteristics of tumor cells. Conclusion A PDTX model can be used as a substitute for cancer patients in clinical practice and may be suitable for clinical pharmacodynamic screening and new drug development. © 2020 Liu et al.The development of CDK 4/6 inhibitors has dramatically changed the therapeutic management of hormone receptor-positive (HR+) and HER2 negative metastatic breast cancer (MBC). In combination with fulvestrant, palbociclib, ribociclib and abemaciclib have each been approved for HR+/HER2- MBC following the results of randomized Phase III studies (PALOMA-3, MONALEESA-3, MONARCH-2) and shown a significant advantage in PFS. Data from clinical trials support the combination with aromatase inhibitors in the first line setting and with fulvestrant in the second line. Each agent is well tolerated, and most of the toxicities observed with this class of drugs are generally easily manageable and free from particular complications. The latest evidence from MONARCH-2 and MONALEESA-3 trials shows benefits in terms of overall survival (OS), suggesting an option of using fulvestrant in combination with CDK 4/6 inhibitors in the first line setting. Additional research is needed to determine optimal treatment sequencing, understand the mechanisms of resistance, and develop novel therapeutic strategies to overcome clinical resistance and further improve the outcomes of patients with HR+/HER- MBC. Key questions in the field include the further impact on progression-free survival, overall survival, and the role of continuing CDK 4/6 blockade beyond progression. The purpose of this review is to describe the clinical relevance of fulvestrant in combination with CDK 4/6 inhibitors in HR+/HER2- MBC patients, as well as to discuss the current controversies and evolving research areas. © 2020 Iorfida et al.Objective Chronic shoulder pain (CSP) is a common health problem associated with shoulder dysfunction and persistent pain for many different reasons. However, the studies of pain-related functional brain regions in CSP have been poorly investigated. The main purpose of our study was to observe whether there are abnormal functional changes in brain regions in patients with CSP by using functional magnetic resonance imaging (fMRI). Patients and Methods We compared the differences of brain regions between 37 patients with CSP and 24 healthy controls (HC) using regional homogeneity (ReHo) method. The patients with chronic shoulder pain and healthy controls were matched for age and gender. Brain regions which had abnormal ReHo values were defined as seed region of interests. The approach of seed-based functional connectivity (FC) was further performed to analyze the connectivity between the seeds and whole brain regions. The relationship between abnormal regions and current clinical pain was also evaluated. selleck kinase inhibitor Results Compared to healthy controls, the patients with CSP showed increased ReHo values in the left middle temporal gyrus and decreased ReHo values in right orbitofrontal cortex (OFC). The seed-based analyses demonstrated decreased connectivity between the right OFC and right rectus, superior frontal gyrus in patients with chronic shoulder pain. However, a correlation between ReHo values and clinical characteristics in CSP patients was not found. Conclusion The observed results indicate that there are abnormal ReHo values in brain regions of patients with CSP, especially in the OFC and middle temporal gyrus. Our findings demonstrate that the experience of CSP patients may be mainly associated with cognitive-affective pain processing, rather than nociception. © 2020 Li et al.Background Although ultrasound-guided transversus abdominis plane block (TAPB) is widely used in multimodal analgesia after cesarean delivery (CD), the complications of TAPB during analgesia after CD have rarely been reported. Methods A total of 84 cases of CD were randomly assigned to either a ropivacaine group (R group) or ropivacaine + dexamethasone group (RD group) in this double-blind trial. The pain site and pain degree at rest and during activity at 2 h, 6 h, 10 h, 12 h, 14 h, 16 h, 20 h, and 24 h after maternal surgery were recorded. The consumption of opioids at 24h, postoperative nausea, vomiting, exhaustion, and other adverse reactions were recorded. Results A total of 80 patients were included in the analysis of results. A total of 19 patients developed ISP, 14 in the R group and 5 in the RD group. The incidence of ISP in the R and RD groups was 35% and 12.5%, respectively. The results described above showed that combining dexamethasone with ropivacaine reduced the incidence of ISP, and the difference was statistically significant (P less then 0.05). Two groups of women with positive ISP had higher values of opioid consumption than women with negative ISP, but the difference was not significant. Conclusion Dexamethasone as an adjuvant for ropivacaine can effectively relieve the ISP of ultrasound-guided TAPB after CD, and can enhance the analgesic effect of ropivacaine. © 2020 Liu et al.Purpose This study aimed to compare the analgesic outcomes between primary and repeated cesarean delivery. Patients and Methods We performed a retrospective analysis based on the medical records of a teaching hospital in China from January 2018 to March 2019. We collected data on demographic characteristics, perioperative complications, anesthesia, and surgical factors for cesarean delivery patients. We also recorded the postoperative analgesic strategy, pain intensity (assessed by the number rating scale) during the first 48 hrs after surgery, hospital cost, and hospital stay. Postoperative inadequate analgesia was defined by a score of ≥ 4 in the number rating scale. Analgesic outcomes after cesarean delivery between primiparas and multiparas were compared using propensity score matching analysis. Moreover, subgroup logistic analysis for different age groups (≥ 35 and less then 35 years) was performed to investigate the effect of the maternal category on postoperative inadequate analgesia. Results A total of 1543 patients were included in the analysis and 571 pairs (1142 patients) were matched in the primiparas and multiparaparas group according to their propensity score.
