Gastric cancer (GC) is characterized by high morbidity and mortality rates. Chinese agarwood comprises the resin-containing wood of Aquilaria sinensis (Lour.) Gilg., traditionally utilized for treating asthma, cardiac ischemia, and tumors. However, comprehensive research regarding its anti-GC effects and underlying mechanisms remains limited. In this study, Chinese agarwood petroleum ether extract (CAPEE) demonstrated potent cytotoxicity against human GC cells, with half maximal inhibitory concentration (IC50) values for AGS, HGC27, and MGC803 cells of 2.89, 2.46, and 2.37 μg·mL-1, respectively, at 48 h. CAPEE significantly induced apoptosis in these GC cells, with B-cell lymphoma-2 (BCL-2) associated X protein (BAX)/BCL-2 antagonist killer 1 (BAK) likely mediating CAPEE-induced apoptosis. Furthermore, CAPEE induced G0/G1 phase cell cycle arrest in human GC cells via activation of the deoxyribonucleic acid (DNA) damage-p21-cyclin D1/cyclin-dependent kinase 4 (CDK4) signaling axis, and increased Fe2+, lipid peroxides and reactive oxygen species (ROS) levels, thereby inducing ferroptosis. Ribonucleic acid (RNA) sequencing, real-time quantitative polymerase chain reaction (RT-qPCR), and Western blotting analyses revealed CAPEE-mediated upregulation of heme oxygenase-1 (HO-1) in human GC cells. RNA interference studies demonstrated that HO-1 knockdown reduced CAPEE sensitivity and inhibited CAPEE-induced ferroptosis in human GC cells. Additionally, CAPEE administration exhibited robust in vivo anti-GC activity without significant toxicity in nude mice while inhibiting tumor cell growth and promoting apoptosis in tumor tissues. These findings indicate that CAPEE suppresses human GC cell growth through upregulation of the DNA damage-p21-cyclin D1/CDK4 signaling axis and HO-1-mediated ferroptosis, suggesting its potential as a candidate drug for GC treatment.

Objective:To explore the relationship between gallbladder polyps and colorectal polyps, providing insights into whether the presence of gallbladder polyps can serve as an indicator for colonoscopy screening.Methods:Clinical data from 2 542 patients who underwent colonoscopy and abdominal ultrasound at the First Affiliated Hospital of Shihezi University between January and December 2022 were retrospectively analyzed. Patients were divided into colorectal polyp group ( n=1 266) and non-colorectal polyp group ( n=1 276) based on colonoscopy findings. Univariate and multivariate Logistic regression models were used to analyze the relationship between gallbladder polyps and colorectal polyps. Results:The prevalence rates of gallbladder polyp in colorectal polyp group and non-colorectal polyp group were 16.67% (211/1 266) and 11.21% (143/1 276). Multivariate Logistic regression analysis showed a lower risk of colorectal polyps in women ( P<0.001, OR=0.523, 95% CI: 0.440-0.622). Age ( P<0.001, OR=1.059, 95% CI: 1.050-1.068), and hypertriglyceridemia ( P=0.013, OR=1.350, 95% CI: 1.066-1.709), low level of high-density lipoprotein ( P<0.001, OR=1.588, 95% CI: 1.280-1.969), and gallbladder polyp ( P<0.001, OR=1.712, 95% CI: 1.344-2.180) were independent risk factors for colorectal polyp. There was no significant difference in hypercholesterolemia, elevated low-density lipoprotein, hyperuricemia, or cholecystectomy between colorectal polyp group and non-colorectal polyp group ( P>0.05). Conclusion:The identification of gallbladder polyps via abdominal ultrasound may indicate a higher likelihood of colorectal polyps in patients, underscoring the need for further colonoscopy screening in individuals with gallbladder polyps.

ObjectiveThe antitumor activity of sesquiterpenoid M36 isolated from Myrrha against human hepatoma HepG2 cells was investigated in this study. MethodHepG2 cells were treated with M36 at different concentrations (0, 2, 4, 6, 8, 10 μmol·L-1). Firstly, the effects of M36 on the proliferation of human hepatoma HepG2 cells were detected by methyl thiazolyl tetrazolium (MTT), colony formation assay, and EdU proliferation assay. Hoechst staining, flow cytometry analysis, and Western blot were used to explore the effect of M36 on the apoptosis of human hepatoma HepG2 cells. Acridine orange staining and western blotting were used to examine the effect of M36 on autophagy in HepG2 cells. Finally, Western blot was used to detect protein expression of cancer-related signaling pathways. ResultCompared with the blank group, M36 treatment significantly inhibited the proliferation of human hepatoma HepG2 cells (P<0.01), and the half inhibitory concentration (IC50) value of M36 for 48 h was 5.03 μmol·L-1, in a dose- and time-dependent manner. M36 was also able to induce apoptosis and autophagy in human hepatoma HepG2 cells. After treatment with 8 μmol·L-1 M36 for 48 hours, the apoptosis rate of HepG2 cells was (42.03±9.65)% (P<0.01). Compared with the blank group, HepG2 cells treated with 4 and 8 μmol·L-1 M36 for 48 h had a significant increase in cleaved poly ADP-ribose polymerase (cleaved-PARP) protein levels (P<0.01). Acridine orange staining showed that autophagy was significantly activated in HepG2 cells treated with 4 and 8 μmol·L-1 M36 for 48 h compared with the blank group (P<0.01), which was further verified by the up-regulation of microtubule-associated protein 1 light chain 3 Ⅱ (LC3 Ⅱ). Western blot results showed that compared with the blank group, the levels of phosphorylated extracellular regulated protein kinase (p-ERK), phosphorylated p38 mitogen-activated protein kinase (p-p38 MAPK), phosphorylated c-Jun N-terminal kinase (p-JNK), and its downstream nuclear transcription factors c-Jun and p-c-Jun protein were significantly increased in M36 group (P<0.05, P<0.01). The mechanism may be related to the up-regulation of MAPK signaling pathway. ConclusionThe sesquiterpenoid M36 isolated from Myrrha inhibits the proliferation of human hepatoma HepG2 cells and promotes apoptosis and autophagy, which may be related to the activation of the MAPK signaling pathway.

Objective:To explore the influencing factors for compliance to colonoscopy screening for colorectal cancer in outpatients.Methods:Patients aged 40-74 years who visited the outpatient gastroenterology department of 7 tertiary hospitals in 7 regions of Xinjiang from January 2022 to June 2022 were enrolled. Recommendations for colonoscopy screening were made according to the patient's medical conditions, and the questionnaire was used to collect information. The Chi-square test was used to compare the differences of compliant and non-compliant patients. Multivariate logistic regression was used to analyze the influencing factors of compliance to colonoscopy screening.Results:A total of 463 valid questionnaires were obtained from 7 centers, in which, 427 outpatients (92.2%) followed the recommendation for colonoscopy screening, and 36 (7.8%) did not. Chi-square test results showed that there were statistically significant differences between the two groups in gender, age, education, subjective cognition of intestinal polyps, personal history of colorectal polyps, family history of colorectal cancer, family history of colorectal polyps, abdominal pain or distension, and defecation habit or stool changes ( P<0.05). The results of multivariate regression analysis showed that the screening compliance of patients aged 40-49 years ( P=0.005, OR=0.141, 95% CI: 0.036-0.549) and 50-59 years ( P=0.039, OR=0.257, 95% CI: 0.071-0.932) was lower than that of patients aged 60-74 years. The screening compliance of patients with high school education ( P=0.011, OR=3.121, 95% CI: 1.304-7.473) and college education or above ( P=0.016, OR=3.544, 95% CI: 1.270-9.890) was higher than those with primary school education and below. Patients with personal history of colorectal polyps ( P=0.015, OR=12.288, 95% CI: 1.629-92.719), family history of colorectal cancer ( P=0.038, OR=8.506, 95% CI: 1.124-64.351) and changes in defecation habit or stool trait ( P=0.039, OR=4.794, 95% CI: 1.085-21.192) also had higher compliance. Conclusion:Age, educational level, personal history of colorectal polyps, and family history of colorectal cancer are related to colonoscopy screening compliance in outpatients of 7 tertiary hospitals in 7 regions of Xinjiang. The independent risk factors affecting compliance to colorectal cancer screening in outpatients are age of 40-59 years, lower educational level, no previous history of polyps or family history of colorectal cancer, and no defecation habit or stool changes.

OBJECTIVE To standardize the English translations of the current Chinese patent medicine (CPM) instructions in order to increase its English translation quality and improve its readability. METHODS In an attempt to standardize its English translation, 64 CPM instructions were collected as samples for translation projects in Trados, using its two core functions of translation memory and terminology, combined with pre-editing (PRE) and post-editing (PE) skills. RESULTS The results showed that translation projects had up to 21.65% perfect match. Based on translation project practice, it is proposed to use the free translation or transcreation plus transliteration method to translate product names of CPM, and apply two human-computer interaction translation modes:“ machine translation (MT)+computer-assisted translation (CAT)+PE” and “PRE+MT+CAT+PE”, which are adopted in the translation of weak literary sections and strong literary sections, respectively. CONCLUSIONS The application of CAT not only improves the translation quality and the translation mode, reduces the translation cost, and maintains the consistency and style of the translation, but also accumulates language assets for future use, providing a novel reference for translating traditional Chinese medicine literature.

Objective:To clarify the risk factors for post-operative central nervous system infection (PCNSI) to provide references for prevention and treatment of PCNSI.Methods:A total of 397 patients with neurosurgery diseases, admitted to and accepted 403 surgeries in our hospital from February 1 st, 2015 to December 30 th, 2015, were chosen in our study; their clinical data were collected. The incidence of PCNSI was analyzed. Risk factors for PCNSI were analyzed by univariate analysis and multivariate Logistic regression analysis. The ajusted specific infection rate of PCNSI was calculated in 12 chief surgeons who performed≥8 operations during the study period to assess the influence of surgeons in PCNSI incidence. Results:The PCNSI incidence in these 397 patients was 9.2% (37/403). The cerebrospinal fluid (CSF) culture positive rate was 29.7% (11/37), including 6 (54.6%) with positive gram staining. Univariate analysis showed that as compared with the non-infected group (366 surgeries), patients in the PCSNI group (37 surgeries) had significantly higher National Nosocomial Infections Surveillance (NNIS) scale, significantly higher proportion of patients with preoperative stay>6 d, significantly longer operative duration, and statistically higher proportion of involvement of scrub nurses with experience in fewer than 8 procedures ( P<0.05). Multivariate Logistic regression analysis showed operative duration ( OR=1.389, 95%CI: 1.202-1.606, P=0.000) and involvement of scrub nurses with experience in fewer than 8 procedures ( OR=2.860, 95%CI: 1.276-6.412, P=0.011) were independent risk factors for PCNSI. After adjustment by NNIS scale, the ajusted specific infection rate of PCNSI in 12 chief surgeons was 20.0%, 23.0%, 17.3%, 18.2%, 13.4%, 12.5%, 6.3%, 8.0%, 5.2%, 4.0%, 0.0%, and 0.0%, respectively, enjoying obvious differences. Conclusion:Specialized infection control training should give to surgeons with high adjusted specific infection rate of PCNSI; this training, shortening operative duration, and training of neurosurgery specialist nurses will be important measures to reduce PCNSI incidence.
