The optimal treatment for liver metastasis from gastric cancer (LMGC) remains uncertain. The relevance of surgical resection is controversial. We conducted a prospective multicenter interventional study of surgical resection for LMGC.

Patients with synchronous or metachronous LMGC who were surgically fit were registered. The primary endpoint was 3-year overall survival (OS) of patients who underwent R0 resection. Secondary endpoints were R0 resection rate, operative morbidity and mortality, 3-year recurrence-free survival (RFS) of R0 patients, and OS in all registered patients.

Seventy patients were registered from 24 institutions between December 2011 and November 2019 and received preoperative chemotherapy. Three patients were ineligible, and 19 patients discontinued treatment, with disease progression in 12, adverse events in 4, and consent withdrawal in 3 before surgery. Of the 48 patients eventually undergoing surgery, R0 resection of the primary and/or metastatic GC was accomplished in 43 patients, while 1 patient discontinued treatment for positive peritoneal lavage cytology and 4 patients were considered ineligible based on postoperative pathological findings other than GC. The R0 resection rate of all eligible patients was 68.3% [95% confidence interval (CI) 55.3-79.4%, 43/63 patients], while that of all resected patients was 89.6% (95% CI 77.3-96.5%, 43/48 patients). Postoperative complications were identified in 12 out of 43 patients (27.9%), and Clavien-Dindo grade III or higher complications occurred in seven patients (16.3%). No hospital mortality was observed.

R0 resection for LMGC could be performed in approximately two-thirds of all eligible patients, with acceptable surgical morbidity and mortality.

In esophageal cancer surgery, it is difficult to perform thorough dissection of lymph nodes along the recurrent laryngeal nerve (RLN-LN). However, there are limited data regarding the necessity of RLN-LN dissection in surgery for superficial esophageal squamous carcinoma (focused on T1b tumor) and its role in locoregional control and accurate nodal staging.

Between 2001 and 2016, 567 patients with pT1N0 and 927 patients with cT1N0 squamous cell carcinoma were identified in a prospectively maintained, single institution esophagectomy registry. Sufficient or insufficient RLN-LN assessment group was defined by receiver operating characteristic curve analysis of the number of RLN-LN harvested. To mitigate bias, inverse probability weighting adjustment and several sensitivity analyses were performed.

In the pT1N0 cohort, patients with sufficient (≥ 4) harvested RLN-LNs showed significantly superior 5-year recurrence-free survival (89.1% versus 74.8%, log-rank P < 0.001). Patients with insufficient RLN-LN esults show the significance of adequate bilateral RLN LN in the surgery for early stage ESCC (particularly those with T1b)T1b), in terms of accurate nodal staging, effective nodal clearance, and reduced regional.The aim of this study is to compare patient-reported cosmesis and satisfaction outcomes between lateral retroperitoneoscopic adrenalectomy (LRA), laparoendoscopic single site and reduced port adrenalectomy (LESS/RP-A) and lateral transperitoneal laparoscopic adrenalectomy (LTA). A total of 26, 86 and 50 patients who underwent LRA, LESS/RP-A and LTA were included in the study. All LESS/RP-A cases were performed taking the transumbilical approach. We mailed a questionnaire to all patients 1, 3, 6, 9 and 12 months after operation. Questionnaires inquiring about cosmesis (0 very ugly, 10 very beautiful) on the basis of a visual analogue scale were administered. The mean scores of cosmesis at postoperative months 1, 3, 6, 9 and 12 were 7.11, 7.00, 6.57, 5.25 and 5.46 for the LRA group, 8.43, 8.86, 8.95, 8.46 and 9.09 for the LESS/RP-A group and 7.18, 7.74, 7.58, 7.44 and 8.09 for the LTA group. The difference in cosmesis score between the LRA and LESS/RP-A groups gradually increased after surgery, and the cosmesis score for the LRA group was significantly lower at every postoperative point. The difference in cosmesis score between the LRA and LTA groups gradually increased after surgery, and the cosmesis score for the LRA group was significantly lower at postoperative months 9 (p = 0.015) and 12 (p = 0.002). This study is the first comprehensive longitudinal analysis of patient-reported cosmesis outcomes between LRA, LESS/RP-A and LTA. LRA was the surgical procedure that resulted in lower cosmesis scores when compared with those following the LESS/RP-A and LTA procedures.Cervical cancer is one of the leading female malignancy tumors worldwide. Structural maintenance of chromosomes 4 (SMC4), a member of the SMC family, is associated with cancer pathogenesis and progression. However, the role of SMC4 in cervical cancer is still unclear. In the study, SMC4 was increased in cervical cancer tissues compared with adjacent normal tissues. The SMC4 knockdown and overexpression were performed in cervical cancer cells. SMC4 knockdown inhibited cell proliferation, colony formation, cell migration and invasion, and suppressed epithelial-mesenchymal transition (EMT). Conversely, SMC4 overexpression exerted opposite effects. Moreover, SMC4 knockdown down-regulated stem cell markers, reduced the capacity of spheroid formation and inactivated NF-κB pathway. SMC4 overexpression contributed to stem cell markers, and stimulated spheroid formation and NF-κB pathway activation. Additionally, BAY11-7082 (an NF-κB inhibitor) alleviated the SMC4-mediated the effects in cervical cancer cells. In conclusion, these findings demonstrated that SMC4 overexpression facilitated the development of cervical cancer cells by activating NF-κBpathway, which provides a new therapeutic target for patients with cervical cancer.The objective of this study was to investigate the effects of replacing antibiotics with Kudzu-leaf flavonoids (KLF) on the growth performances, gut epithelial development, and gastrointestinal bacteria diversities of Yellow-feathered broilers. For this purpose, total of 216 1-day-old male Yellow-feathered chickens with the similar birth weight (31.0  ±  1.0 g) were randomly divided into 3 treatments the control treatment (CON), the kudzu-leaf flavonoids supplement treatment (KLF), and the antibiotics supplement treatment (AGP). All birds were provided with a 56 d-feeding procedure, followed by the measurement of production performances, immune organs, blood anti-oxidant parameters, intestine epithelium development, and cecal microbiota. Results showed the feed conversion ratio significantly decreased after KLF supplement compared with CON (P   less then  0.05). KLF supplement partly promoted the anti-oxidant capacity on account of the increased activity of Superoxide dismutase (SOD) and the decrease content of malondialdehyde (MDA). Further, as referred to the gastrointestinal development and bacteria, ratio of villus/crypt significantly increased of ileum in KLF treatment (P  less then   0.05) while a significant promition of bacterial diversity and partial representative probiotic bacteria (P   less then  0.05) after KLF supplementation. Moreover, correlation analysis indicated that probitics including Bifidobacterium, Butyricimonas, Lactobacillus and Streptococcus positively correlated with production performances. In conclusion, KLF supplement may promote feed efficiency and benefit the gastrointestinal health through improving gut bacterial diversity and probiotic bacteria. The KLF might be applied as a proper antibiotic alternative.In addition to causing the nondisjunction of maize B and normal A chromosomes at the second megaspore division during embryo sac development, the r-X1 deletion results in terminal deficiencies (TDs) in various A chromosomal arms, but whether the r-X1 deletion also induces TDs of the maize B chromosome remains unknown. To answer this question, the chromosomal composition in the r-X1-containing progeny of r-X1/R-r female parents carrying two standard B chromosomes was determined. Nine of 104 (8.7%) examined kernels contained a smaller telocentric B chromosome, and one of these (designated Bdef-1) was further identified as a TD with a breakpoint in the third distal heterochromatic region of the B chromosome. Thus, the results indicated that the r-X1 deletion could also induce TDs of the maize B chromosome during megaspore divisions. The Bdef-1 chromosome lacked nondisjunctional behavior, and this behavior was restored by the presence of the B chromosome in the cell. A transmission analysis of the Bdef-1 chromosome revealed that loss of the distal portion of the B chromosome reduced female but not male transmission of the B chromosome. Furthermore, the Bdef-1 chromosome was used to more finely map B-derived miRNA genes on the B chromosome. Our results indicate that the r-X1 deletion results in TDs of the B chromosome in maize, and the r-X1 deletion system can thus be used to generate a series of terminally truncated B chromosomes that may be used to map features of the B chromosome, including genes and properties related to B chromosome functions.Age is an important risk factor for different diseases. The same mechanisms that promote aging are involved in the development and progression of age-associated diseases. Polyphenols are organic compounds found in fruits and vegetables. Due to their beneficial properties (e.g. antioxidant and anti-inflammatory), polyphenols have been extensively used for treating chronic diseases. To exert their functions, polyphenols target various molecular mechanisms and signaling pathways, such as mTOR, NF-κB, and Wnt/β-catenin. Wnt signaling is a critical pathway for developmental processes. Besides, dysregulation of this signaling pathway has been observed in various diseases. Several investigations have been conducted on Wnt inhibitors at pre-clinical stages, showing promising results. Herein, we review the studies dealing with the role of polyphenols in targeting the Wnt signaling pathways in aging processes and age-associated diseases, including cancer, diabetes, Alzheimer's disease, osteoporosis, and Parkinson's disease.Carpal scaphoid fracture is rare in children and is important to recognize early because of an increased risk for serious complications including non-union, avascular necrosis, and osteoarthritis. In the skeletally immature patient, a scaphoid fracture can easily escape detection due to clinical and diagnostic imaging interpretation errors. selleck products We report complete healing of a pediatric scaphoid non-union fracture after a remarkable delay in diagnosis and emphasize the considerable biological potential of the immature skeleton, coupled with proper stabilization, for good clinical outcomes.

Tibetan hulless barley (Hordeum vulgare var. nudum), adjusting to the harsh environment on Qinghai-Tibet Plateau, is a good subject for analyzing drought tolerance mechanism. Several unannotated differentially expressed genes (DEGs) were identified through our previous RNA-Seq study using two hulless barley accessions with contrasting drought tolerance. One of these DEGs, HVU010048.2, showed up-regulated pattern under dehydration stress in both drought tolerant (DT) and drought susceptible (DS) accessions, while its function in drought resistance remains unknown. This new gene was named as HvLRX (light responsive X), because its expression was induced under high light intensity while suppressed under dark.

To provide preliminary bioinformatics prediction, expression pattern, and drought resistance function of this new gene.

Bioinformatics analysis of HvLRX were conducted by MEGA, PlantCARE, ProtParam, CELLO et al. The expression pattern of HvLRX under different light intensity, dehydration shock, gradual drought stress, NaCl stress, polyethylene glycol (PEG) 6000 stress and abscisic acid (ABA) treatment was investigated by quantitative reverse transcription-polymerase chain reaction (RT-qPCR).
