Background: Gastric cancer (GC) is a malignant tumor with seriously poor outcomes. Studies have shown that microRNAs (miRNAs) play an omnifarious regulatory effect in GC. However, the role of miR-3650 in the progression of GC is not well known.

Background: A recent study has reported that miR-3650 expression was significant reduced in hepatocellular carcinoma and predicted poor prognosis. However, the role of miR-3650 in nasopharyngeal carcinoma (NPC) remains indefinite.

Methods: Total 140 cases of NPCs were included in this study.

Objective: Organoids have recently been used as models to screen chemotherapy drugs in combination with hyperthermia treatment in colorectal cancer. Our research aimed to establish a library of patient-derived colorectal cancer organoids to evaluate synergism between chemotherapy drugs and hyperthermia; validate an index of the hyperthermia chemotherapy sensitization enhancement ratio (HCSER) to identify the chemotherapeutics most enhanced by hyperthermia; and recommend chemotherapy drugs for hyperthermic intraperitoneal treatment.

Methods: Organoids were grown from cells extracted from colorectal cancer patient samples or colorectal cancer cell lines.

Objective: To compare the efficacy and safety of hyperthermic intravesical chemotherapy (HIVEC) and intravesical chemotherapy (IVEC) in patients with intermediate and high risk nonmuscle-invasive bladder cancer (NMIBC) after transurethral resection.

Methods: We included 560 patients diagnosed with primary or recurrent NMIBC between April 2009 and December 2015 at 1 of 6 tertiary centers. We matched 364 intermediate or high risk cases and divided them into 2 groups: the HIVEC+IVEC group [chemohyperthermia (CHT) composed of 3 consecutive sessions followed by intravesical instillation without hyperthermia] and the IVEC group (intravesical instillation without hyperthermia).

Objective: Systemic chemotherapy has limited efficacy in the treatment of peritoneal metastasis (PM) in gastric cancer (GC). Hyperthermic intraperitoneal chemotherapy (HIPEC) combined with complete cytoreductive surgery (CRS) has shown promising outcomes but remains controversial. The present study aimed to evaluate the safety and efficacy of HIPEC without CRS in GC patients with PM.

Chemical investigations of the 75% EtOH extract of the leaves of Tripterygium wilfordii obtained five undescribed naturally occurring sesquiterpenes with dihydro-β-agarofuran skeleton, tripteresters A-E (1-5), along with eight known analogues (6-13). Their chemical structures were elucidated by a combination of spectroscopic the comprehensive spectroscopic analyses, electronic circular dichroism (ECD) exciton chirality, and quantum chemical calculations ECD. In the bioactivity assay, their neuroprotective properties against hydrogen peroxide (HO)-induced oxidative damage in human neuroblastoma SH-SY5Y cells were investigated, and compounds 4, 8, and 12 revealed moderate protective activity at a concentration of 12.

Importance: Interval cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) showed promising oncologic outcomes for patients with advanced ovarian cancer, but a large-scale, multicenter study to evaluate the efficacy of HIPEC combined with primary cytoreductive surgery (PCS) has yet to be conducted.

Objective: To compare survival outcomes between PCS with HIPEC vs PCS alone for patients with stage III epithelial ovarian cancer.

Design, Setting, And Participants: This cohort study was conducted from January 2010 to May 2017 at 5 high-volume institutions in China.

Introduction: The role of reproductive factors in the development of chronic hepatitis B (CHB) remains unknown. We assessed the potential contributions of gender, menopausal status, and menarche age to liver fibrosis in CHB.

Methods: A cross-sectional prospective study included 716 women and 716 age-matched men with CHB who were not currently receiving antiviral therapy.

Triptersinoids A-E (1-5), five undescribed highly oxygenated dihydro-β-agarofuran type sesquiterpenoid polyesters, along with three known analogues were isolated from the aqueous EtOH extracts of the dried leaves of Tripterygium wilfordii. Spectroscopic techniques were used for the elucidation of their chemical structures, and the absolute configurations determined by means of electron circular dichroism (ECD) studies, including octant rule of saturated cyclohexanone and comparison between the experimental and calculated ECD data. These compounds were evaluated for the anti-inflammatory activities against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW 264.

Fifteen new dihydro-β-agarofuran-type sesquiterpenoids, tripterfordins A-O, were obtained from the aqueous EtOH extracts of the leaves of . These constituted a class of highly oxygenated tricyclic sesquiterpenoid polyesters with a cinnamoyloxy group at C-1. The assignments of their structures were conducted via extensive analyses of the spectroscopic data and comparison of experimental and calculated ECD data.

Background & Aims: The role of cigarette smoking in the development of chronic hepatitis B (CHB) remains poorly understood. We assessed the potential contributions of cigarette smoking to liver fibrosis and its regression after starting antiviral therapy in CHB patients.

Methods: In this cohort study, 2144 consecutive male CHB patients under no antiviral therapy were evaluated and 206 patients with significant liver fibrosis (≥F2) initiating antiviral therapy had longitudinal follow-up.

Background/aims: The development of multidrug resistance (MDR), which results in disease recurrence and metastasis, is a crucial obstacle to successful chemotherapy for patients with gastric cancer (GC). Long non-coding RNAs (lncRNAs) have been found to play various roles in cancer. This study aimed to investigate the effect of XLOC_006753 on the development of MDR in GC cells.

Background: Gastric cancer (GC) is a common malignancy and frequent cause of cancer-related death. Long non-coding RNAs (lncRNAs) have emerged as important regulators and tissue-specific biomarkers of multiple cancers, including GC. Recent evidence has indicated that the novel lncRNA LINC01133 plays an important role in cancer progression and metastasis.

Background/aims: Considerable evidence indicates that long noncoding RNAs (lncRNAs) exert importantly regulatory functions during human cancer initiation and progression and are promising biotargets in the flight against cancer.

Methods: In this study, we evaluated the role of the lncRNA LINC01133 in esophageal squamous cell carcinoma (ESCC). LINC01133 expression in ESCC was examined by quantitative real-time PCR.

Four new compounds (1, 2, 7 and 8) and twenty known compounds were isolated from the flower buds of Lonicera japonica. Their structures were determined by extensive NMR and HR-ESIMS spectroscopic data analyses. Among them, compounds 1 and 2 are a pair of diastereoisomers possessing a rare chemical structure, and their absolute configurations were determined by comparing their experimental and calculated ECD spectra.
