Investigation and analysis of daily diet and living habits of Hashimoto's thyroiditis patients / 中华地方病学杂志

Objective:To investigate the daily diet and living habits of Hashimoto's thyroiditis (HT) patients, and to explore the influencing factors of HT.Methods:The patients admitted to the Thyroid Surgery Clinic of Cancer Hospital Affiliated to Harbin Medical University from March to December 2021 were selected as the investigation subjects and were divided into observation group (106 patients with HT) and control group (63 healthy people). Questionnaire was used to collect the information of daily diet and living habits of the two groups, and physical examination was used to collect the information of height and weight. The levels of serum thyroid function indicators thyroid stimulating hormone (TSH), free triiodothyronine (FT 3) and free thyroxin (FT 4) were tested by automatic chemiluminescence immunoassay, and the comparison and analysis were conducted between the two groups. Multivariate logistic regression was used to analyze the influencing factors of HT. Results:The results of univariate analysis showed that there were significant differences in sex ratio and serum TSH levels between the two groups ( P < 0.05); the proportion of people in observation group who slept for less than 6 hours per day, frequently looked at their mobile phones, ate fried food ≥1 time per week, and ate meat ≥1 kg per week was higher than that in control group; however, the proportion of people in observation group who drank tea ≥1 time per week, smoked ≥1 time per week, had a salty daily taste, ate nuts ≥1 time per week, and ate vegetables ≥1 kg per week was lower than that in control group, and the differences were statistically significant ( P < 0.05). The results of multivariate logistic regression analysis showed that female, slept duration < 6 hours/day, weekly meat consumption ≥1 kg, and elevated serum TSH levels were risk factors for the onset of HT [odds ratios ( OR) = 3.37, 4.11, 2.48, 1.14, and 95% confidence intervals ( CI): 1.08 - 10.55, 1.46 - 11.59, 1.00 - 6.51, 1.00 - 1.30]; eating ≥1 kg of vegetables per week was a protective factor for the onset of HT ( OR = 0.36, 95% CI: 0.17 - 0.79). Conclusion:Female, poor diet and lifestyle habits are risk factors for the onset of HT.

Characteristics, Prognostic Factors, and Survival of Patients with NK/T-Cell Lymphoma of Non-upper Aerodigestive Tract: A 17-Year Single-Center Experience / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The extranodal natural killer (NK)/T-cell lymphoma (NKTCL) of non-upper aerodigestive tract (NUAT) was found to have clinical heterogeneity compared with NKTCL of the upper aerodigestive tract (UAT) in small scale studies. We conducted this study in a much larger cohort to analyze the clinical characteristics, prognostic factors, treatment modality, and clinical outcomes of patients with NUAT-NKTCL. MATERIALS AND METHODS: From January 2001 to December 2017, a total of 757 NKTCL patients were identified and included in this study, including 92 NUAT-NKTCL patients (12.2%) and 665 UAT-NKTCLpatients (87.8%). RESULTS: NUAT-NKTCL patients had relatively poorer performance status, more unfavorable prognostic factors, and more advanced stage, compared with UAT-NKTCL patients. The 5-year overall survival (OS) was 34.7% for NUAT-NKTCL, which was significantly worse than UAT-NKTCL (64.2%, p<0.001). The median OS duration was 30.9 months for NUAT-NKTCL. Multivariate analysis showed that presence with B symptoms and elevated serum lactate dehydrogenase independently predicted worse OS. International prognostic index score and prognostic index of natural killer lymphoma score still had prognostic values in NUAT-NKTCL, while the Ann Arbor system could not accurately predict the OS. CONCLUSION: NUAT-NKTCL is a distinctive subtype of NKTCL in many aspects. Patients with NUAT-NKTCL have relatively poorer performance status, more unfavorable prognostic factors, more advanced stage, and poorer prognosis.

Potential Mechanism of Jiaotaiwan for Diabetes Based on Integrative Pharmacology Method / 中国实验方剂学杂志

Objective: Jiaotaiwan is a classic prescription in traditional Chinese medicine for insomnia. Modern clinical research has proved its anti-diabetes effect by "the same treatment for different diseases" theory, so it is necessary to study its pharmacological mechanism for anti-diabetes effect. Method: In this study, the integrative pharmacology platform of traditional Chinese medicine (TCMIP) was used to explore the potential target and mechanism of Jiaotaiwan, and construct its core target network for diabetes. Then the enrich analysis of GO and KEGG on key targets was conducted to build the visual multilayer association network of "Jiaotaiwan-active composition-core target-key pathway". Result:28 active ingredients were obtained from Jiaotaiwan in this study. Its anti-diabetes effect was relevant to 187 core targets,including 15 known disease targets such as vasopressin V2 receptor (AVPR2), receptor activity-modifying protein 1 (RAMP1), receptor activity-modifying protein 3 (RAMP3), insulin receptor (INSR), and insulin-like growth factor 1 receptor (IGF1R); as well as 71 predictive drug targets such as cyclin-dependent kinase 9 (CDK9), glucokinase (GCK), NF-kappa-B inhibitor alpha (NFKBIA), NF-kappa-B p100 subunit (NFKB2), and hypoxia inducible factor-1 alpha (HIF1A). Conclusion:The anti-diabetes mechanism of Jiaotaiwan may be associated with activation of adenylate cyclase activity, cellular response to glucagon stimulus, activation of mitogen-activated protein kinase (MAPK) activity, endocrine system, gonadotropin-releasing hormone (GnRH) signaling pathway, Chemokine signaling pathway, phosphatidylinositol 3-kinase-serine/threonine kinases (PI3K-Akt) signaling pathway and other related biological processes and pathways. This study provides a scientific evidence for further study of the anti-diabetes mechanism of Jiaotaiwan.

Rebamipide repairs injury of small intestinal epithelial barrier induced by aspirin in mice / 中国病理生理杂志

AIM:To investigate whether rebamipide repairs the small intestinal epithelial barrier in aspirin-induced small intestinal injury (SII) in mice and its mechanism.METHODS:Small intestinal injury was induced by aspirin (200 mg · kg-1 · d-1 for 5 d) in BALB/c mice.Based on the treatment with aspirin and/or rebamipide (320 mg ·kg-1 · d-1),the mice were divided into 4 groups (n =18 in each group).The living mice in each group (n =6) were sacrificed via cervical dislocation method at day 0,day 5,and day 10.The structure and function of intestinal barrier and the levels of the signaling pathway factors were measured by transmission electron microscopy,immunohistochemistry,qPCR,and Western blot.RESULTS:Tight junctions between intestinal epithelial cells improved significantly after rebamipide treatment.The expression of ZO-1 and occludin in the injured small intestine showed a gradually increasing trend after rebamipide administration (P ＜ 0.05).There was a decreased trend of D-lactate level in rebamipide-treated SII mice (P ＜ 0.05).The expression of cyolooxygenase-2 (COX-2),β-catenin,and c-Myc,and prostaglandin E2 concentration in small intestinal tissues were significantly increased in rebamipide treatment group (P ＜ 0.05).However,down-regulated COX-1 expression in the SII mice was sustained at a low level after rebamipide administration.CONCLUSION:Rebamipide repairs the injury of small intestinal mucosa and improves the structure and function of small intestinal barrier in aspirininduced SII mice by up-regulating the expression of COX-2.

Synthesis and structure-activity relationship of cycloberberine as anti-cancer agent / 药学学报

A series of cycloberberine derivatives were designed, synthesized and evaluated for their anti-cancer activities in vitro. Among these analogs, compounds 6c, 6e and 6g showed strong inhibition on human HepG2 cells. They afforded a potent effect against DOX-resistant MCF-7 breast cells as well. The primary mechanism showed that cell cycle was blocked at G2/M phase of HepG2 cells treated with 6g using flow cytometry assay. It significantly inhibited the activity of DNA Top I at the concentration of 0.1 mg mL-1. Our results provided a basis for the development of this kind of compounds as novel anti-cancer agents.
