The purpose of this study was to explore the changes in blood pressure in patients with concurrent gastric cancer and hypertension after gastrectomy, and to identify the factors that affect the changes in blood pressure.

Patients with concurrent gastric cancer and hypertension who underwent gastrectomy were retrospectively analyzed from January 2013 to December 2018. The pre- and 6-month postoperative medical records were compared. Predictors for the remission of hypertension were analyzed.

A total of 143 patients with concurrent gastric cancer and hypertension were included in this study. The number of patients with complete remission, partial remission and no remission were 67 (46.9%), 12 (8.4%) and 64 (44.7%), respectively. The average of weight and BMI (body mass index) before gastrectomy were 63.0 ± 9.7 kg and 23.4 ± 2.9 kg/m

, respectively, which were significantly higher than those 6-month postgastrectomy 54.8 ± 9.8 kg and 20.4 ± 3.1 kg/m

, respectively (p<0.001). The average number of antihssion of hypertension 6 months after gastrectomy.

The presence of circulating plasma cells (cPCs) was associated with a worse prognosis in multiple myeloma patients. However, the underlying mechanisms involved in the migration and invasion of bone marrow myeloma cells (BMMCs) to cPCs remains unclear. Here, we investigate the possible factors related to hematogenous myeloma cell dissemination and potential regulatory mechanisms.

BMMCs and cPCs of five extramedullary plasmacytoma (EMP) patients were selected for single cell RNA sequencing, We found that the expression level of sphingosine-1-phosphate receptor 2 (

) was lower in cPCs compared with that in BMMCs. Then, we investigated the effect of S1PR2 in cell migration and invasion through pharmacologic inhibition with a

-selective antagonist JTE-013 or knockdown of

expression in MM cell line U266.

The results showed that

inhibition with JTE-013 or

-shRNA significantly promoted cell migration and invasion in U266 cells. We measured the expression of invasion-related proteins by Western blot and found that knockdown of

could reduce MMP-9 expression in U266 cells. Furthermore, we found NF-κB pathway may mediate the inhibition effects of

on cell migration and invasion in MM cells.

Our findings demonstrated that

downregulation may contribute to the initial extramedullary translocation by promoting cell migration and invasion through NF-κB pathway activation.

Chordoma, a rare bone tumor, occurs most commonly at the sacrococcygeal and skull base region. To date, chemotherapy is used to treat patients with advanced-stage chordoma. However, multidrug resistance (MDR) greatly hinders the effect of chemotherapy in chordoma. Here, we studied the correlation between KCNQ1OT1 and chemotherapy resistance.

RT-PCR assay was used to examine KCNQ1OT1, miR-27b-3p, and ATF2 mRNA expression. CCK8 assay was exercised to detect IC

values of cisplatin in chordoma cells. ATF2 protein expression was detected by Western blot.

KCNQ1OT1 was increased in chemotherapy-resistant patients and cisplatin-resistant cells, and downregulation of KCNQ1OT1 expression weakened MDR in chordoma. In addition, KCNQ1OT1 promoted MDR in chordoma by sponging miR-27b-3p and subsequently increasing ATF2 expression.

KCNQ1OT1 is proved to be strikingly raised in the chemotherapy-resistant group and to promote MDR in chordoma. Our findings demonstrated the role of the KCNQ1OT1/miR-27b-3p/ATF2 axis in MDR of chordoma, which provides new insight into the molecular mechanism of chordoma MDR, and may determine the effect of therapy after receiving chemotherapy by detecting the expression of KCNQ1OT1 in serum.

Gastric cancer (GC), one of the most prevalent malignancies, is the third-leading cause of cancer-related deaths globally. The aim of this study is to investigate the involvement of non-structural maintenance of chromosomes condensin I complex subunit G (NCAPG) in the prognosis of GC.

Western blotting and immunostaining were employed to measure the NCAPG level in gastric tissues and cells. Kaplan-Meier analysis was applied to analyze the prognostic value of NCAPG in GC. RNA interference was applied to investigate the influence of the NCAPG silencing on GC cell growth and spread.

NCAPG overexpression was associated with several clinicopathologic characteristics, including nodal status (P = 0.0378), distant metastasis (P = 0.0088), staging (P = 0.0230), vascular invasion (P = 0.0012), and disease-free survival (P = 0.004). Kaplan-Meier analysis revealed that NCAPG overexpression was positively correlated to poor GC patients disease-free and overall survival (P = 0.004 and P < 0.001, respectively). Tegatrabetan Univariate Cox regression analysis showed that the overexpression of NCAPG was a prognostic biomarker of GC (P = 0.005). In cultured GC cells, the knockdown of NCAPG suppressed cell proliferation, migration and invasion. Meanwhile, further studies revealed that the NCAPG silencing induces the G0/G1 cell cycle arrest and accordingly represses cell division. Finally, Western blotting showed that NCPAG knockdown dysregulated cell cycle- and epithelial-mesenchymal transition-related molecules.

Overall, the results reveal that NCAPG overexpression is a candidate prognostic biomarker and potential therapeutic target in GC.

The efficacy of surgery as the primary treatment modality for nasopharyngeal carcinoma (NPC) is yet to be clarified. Therefore, we aimed to explore the short- and long-term efficacy of surgery for early-stage NPC.

We retrospectively evaluated 341 patients diagnosed with early-stage NPC between September 2010 and December 2015. Among them, 58 patients underwent endoscopic nasopharyngectomy combined with chemoradiotherapy, whereas 283 patients underwent conventional chemoradiotherapy. The patients who underwent concurrent chemoradiotherapy or radiotherapy alone were matched to patients who underwent surgery in a 12 ratio using propensity score matching to analyze the clinical efficacy of each therapeutic modality. The primary endpoint was survival, and the secondary endpoints were tumor regression rate and reduction in Epstein-Barr virus (EBV)-DNA levels.

After matching, 156 patients were enrolled (58 patients in the surgery group; 98 patients in the non-surgery group). The baseline data of the matched patients had good inter-group comparability (All P>0.
