Aim To study the effect of G protein-coupled estrogen receptor(GPER)inhibitor G15 on the sensitivity of breast cancer tamoxifen-resistant cells to T-47DTR. Methods Experiments were carried out with 4-hydroxytamoxifen(4-OHT),the active form of tamoxifen in vivo. The sensitivity of tamoxifen-resistant breast cancer cell line T-47DTR and its parental cell line T-47D to tamoxifen was detected by MTT assay; the expression of GPER protein was analyzed by plasma separation of inhibitor G15; the effect of 4-OHT combined with G15 on the apoptosis of T-47DTR cells was analyzed by flow cytometry AnnexinV-FITC/PI double staining; the expression levels of apoptosis-related proteins Bax,Bcl-2,caspase-3,cleaved caspase-3,caspase-9,cleaved caspase-9 were analysed by Western blot. Results(1)Compared with the parental cell T-47D,the resistance of T-47DTR-resistant cells to 4-OHT was significantly enhanced.(2)When 4-OHT(2 μmol·L-1)was administered,the membrane distribution of GPER increased,indicating that GPER was activated in T-47DTR-resistant cells compared with the control group; Compared with OHT,the use of G15(5 μmol·L-1)and OHT significantly reduced the expression of GPER.(3)GPER inhibitor G15 could increase the apoptotic rate of T-47DTR-resistant cells while down-regulating the anti-apoptotic protein Bcl-2 and up-regulating the expression of pro-apoptotic proteins Bax,cleaved caspase-3,cleaved caspase-9. Conclusions The GPER inhibitor G15 increases the apoptosis of T-47DTR cells and restores the sensitivity of drug-resistant cells to tamoxifen.

Objective: To analyze the survival of newly diagnosed malignant tumors in cancer registration areas of Hubei Province from 2013 to 2015. Methods: From January 1, 2013 to December 31, 2015, all newly diagnosed malignant tumors were collected from cancer registration areas in Hubei Province, and patients were followed up using a combination of active and passive methods. Cancer survival was analyzed using the strs package in Stata software. Observed and expected survival were calculated using the life table and Ederer Ⅱ methods, and the difference in survival rate of patients with different sex, age, urban and rural areas and different cancer species was compared. Results: From 2013 to 2015, 83 987 new malignant tumors were diagnosed in cancer registration areas in Hubei Province, including 45 742 males (54.46%) and 38245 females (45.54%). The overall 5-year relative survival rate was 41.46%, 34.43% for men and 49.63% for women. With the increase of age, the observed survival rate and relative survival rate of patients of different genders showed a decreasing trend. The 5-year relative survival rate of patients with malignant tumors was 47.58% in urban areas and 26.58% in rural areas. The observed survival rate and relative survival rate in rural areas were significantly lower than those in urban areas. The overall 5-year relative survival rates for common malignancies were 20.61% for lung cancer, 15.36% for liver cancer, 22.89% for esophageal cancer, 34.92% for gastric cancer, and 54.87% for colorectal cancer. In addition, the 5-year relative survival rates of common malignant tumors in women were 78.65% for breast cancer and 52.55% for cervical cancer. Conclusions: In Hubei Province, the survival rate of malignant tumors is different among different genders, regions, age groups and cancer species. Prevention and treatment and health education should be strengthened for malignant tumor patients in rural areas and those with high incidence and low survival rate such as liver cancer and lung cancer, and relevant strategies should be formulated according to the gender and age distribution characteristics of different cancer species.

Objective: To investigate the association between dietary pattern and cognitive performance in local residents aged ≥50 years in Shanghai. Methods: Data were obtained from the second round of Study of Global Ageing and Adult Health (SAGE) survey in Shanghai. Dietary patterns were surveyed by factor analysis. Cognitive tests were conducted to assess subjects' cognitive performance, including verbal recall, verbal fluency and digit test. Multiple linear regression analysis was used to evaluate the relationship between dietary patterns and cognition performance. Results: A total of 4 132 subjects with complete dietary and cognitive performance test data were included. Factor analysis was used to obtain three dietary patterns: including plant-based pattern, high animal-food pattern, high salt-oil pattern. After controlling for gender, age, education level and other factors, it was found that plant-based pattern (β=0.26,95%CI: 0.17-0.36) and high animal-food pattern (β=0.18, 95%CI:0.06-0.29) were positively associated with total cognitive test score while high salt-oil pattern (β=-0.28, 95%CI:-0.85--0.07) was negatively associated with verbal fluency test score. Conclusion: A dietary pattern with high intake of plant food and appropriate intake of animal food might be associated with better cognitive function of residents aged ≥50 years.

Objective: To examine the independent and combined effects of pre-pregnancy BMI and gestational diabetes (GDM) on early adiposity rebound (AR) timing in children. Methods: Based on the "Ma'anshan Birth Cohort Study", 2 896 eligible maternal and infant pairs were recruited. In the cohort, we collected pre-pregnancy height, weight, 24 to 28 weeks GDM diagnosis, follow-up at 42 days, three months, six months, nine months of age, and every six months after one year of age, and continuously followed up to 6 years old, and obtained the child's length/height, weight, and other data. The intensity of the association between pre-pregnancy BMI, GDM, and early AR timing was analyzed by the multivariate logistic regression model. Multiplication and additive models were used to analyze how pre-pregnancy BMI and GDM influenced early AR timing in children. Results: The prevalence of underweight, average weight, overweight, and obesity before pregnancy were 23.2% (672), 66.4% (1 923), 8.7% (251), and 1.7% (50). The prevalence of GDM was 12.4%. We found that 39.3% of children had AR, and the average age at AR was (4.38±1.08). The results of multifactorial logistic regression analysis showed that pre-pregnancy overweight (OR=1.67,95%CI:1.27-2.19), pre-pregnancy obesity (OR=3.05,95%CI:1.66-5.56), and maternal GDM (OR=1.40,95%CI:1.11-1.76) were risk factors for early AR timing in children. In contrast, pre-pregnancy underweight (OR=0.60,95%CI:0.49-0.73) was a protective factor for early AR timing in children. Compared with the different effects of pre-pregnancy overweight/obesity and maternal GDM alone, the combined effect caused a higher risk of early AR timing in children, with OR values (95%CI) were 2.03 (1.20-3.44), 3.43 (1.06-11.12), respectively. The multiplication and additive models showed no interaction between pre-pregnancy BMI and GDM-influenced early AR timing in children. Conclusion: Higher pre-pregnancy BMI and maternal GDM are the independent risk factors for the early AR timing in children, and the co-occurrence of the two is higher risks, but there was no statistical interaction.

Circular RNAs (circRNAs) are a class of endogenous, covalently closed, single-stranded RNA without 3'-poly(A) and 5'-cap structures. CircRNAs are characterized by universality, diversity, stability and conservation, and have been found to regulate mammalian transcription and be translated into proteins. In this review, we summarized the biogenesis, classification, expression, distribution, biological functions and regulation of circRNAs. In addition, we discussed the association of circRNAs with diseases and the methods for identification and characterization of circRNAs. Finally, we speculated the application prospect and research direction of circRNAs.

Objective:To observe the therapeutic effect of acupuncture-moxibustion at different intervals on persistent allergic rhinitis. Methods: A total of 90 patients conforming to the inclusion criteria were randomized into three groups named A, B and C by randomized block method. Patients in all three groups received the same treatment of acupuncture and herbal cake-partitioned moxibustion at the same acupoints, while the treatment frequency was different. Patients in group A received the treatment once a week, group B twice a week and group C three times a week, and all the treatment lasted for 4 weeks. The total nasal symptom score (TNSS), total ocular symptom score (TOSS) and Sino-nasal outcome test-20 (SNOT-20) were evaluated before and after treatment. The self-rating score of symptoms was evaluated during treatment and 2 weeks after treatment. Results: The total effective rate was 80.0% in group A, 93.3% in group B, and 100.0% in group C. The total effective rate in group A was statistically different from that in group B and group C (both P＜0.05), but there was no significant inter-group difference in total effective rate between group B and group C (P＞0.05). After treatment, scores of TNSS, TOSS and SNOT-20 in all three groups dropped significantly, and statistically different from those before treatment (all P＜0.05); between-group comparison showed group B and group C decreased more obvious than group A (all P＜0.05). In self-rating score of symptoms, there were no inter-group statistically significant differences in the first 3-week treatment (all P＞0.05); after 4-week treatment, the score in group A was higher than that in group B and group C, and showed statistical significant (both P＜0.05); at 2 weeks after treatment, the score in group A was higher than that in group B and group C based on an everyday record, showing statistical significance (both P＜0.05). At the 11th day after treatment, the score in group B was higher than that in group C (P＜0.05). There were no significant differences between group B and group C at other time points (all P＞0.05). Conclusion: All three protocols are effective for allergic rhinitis. With the increase of treatment frequency, the therapeutic efficacy with a treatment frequency of twice a week and three times a week is superior to that of once a week. Frequency of three times a week has a better long-term effect than once and twice a week, together with the least fluctuation of symptoms.

OBJECTIVETo investigate effects of biejiajian pill (BP) on the proliferation, adhesion, and invasion of hepatoma carcinoma cells (HepG2), and to primarily explore the mechanisms for fighting against metastasis and invasion.

METHODSUsing sero-pharmacological methods, HepG2 cells were respectively cultured by high and middle dose BP containing serums and the vehicle serum. Using MTT colorimetry, cell adhesion test, and Transwell invasion test, effects of BP on the proliferation, adhesion, and invasion of HepG2 cells were detected, thus further exploring the mechanisms for fighting against the metastasis and invasion of HepG2 cells.

RESULTSHigh and middle dose BP containing serums could significantly prohibit the growth and proliferation, the adhesion and invasion of HepG2 cells on the basilar membrane. Besides, these effects were correlated with the concentrations of BP.

CONCLUSIONBP could effectively inhibit the growth and proliferation, adhesion and invasion of HepG2 cells.

OBJECTIVETo assess the association between matrix metalloproteinase-3 (MM-3) gene polymorphisms and subtypes of ischemic stroke (IS) in northern Han Chinese population.

METHODSA total of 289 patients with acute IS (within 3 days after the onset, including 185 with large artery atherosclerosis (LAA) and 104 for small artery occlusion (SAO)) and 175 matched healthy controls were recruited for this case-control study. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) or sequenc-based typing (SBT) was carried out to analyze 3 SNPs of the MMP-3 gene.

RESULTSAn incomplete linkage disequilibrium (LD) block was constructed with the 3 SNPs, and the distribution of genotypes of the 3 SNPs differed between the LAA group and controls in a dominant model: Carriers of 5A allele (5A5A+5A6A) of the rs3025058 locus were 1.72 times more susceptible to LAA stroke compared with carriers of 6A6A alleles (P=0.017, OR=1.72, 95% CI: 1.10-2.69), carriers of G alleles (GG+AG) of the rs522616 locus were 0.52 times more susceptible to LAA stroke compared with carriers of AA alleles (P=0.005, OR=0.52, 95% CI: 0.33-0.82), whilst carriers of A allele of the rs679620 locus were 1.55 times more susceptible to LAA stroke compared with carriers of GG alleles (P=0.042, OR=1.55, 95% CI: 1.01-2.37). However, no significant difference has been found between particular genotypes of such SNPs between SAO patients and controls (P> 0.05). Furthermore, 5A-A-A and 6A-A-A haplotypes were significantly more common in LAA group than the controls (P< 0.05), whilst 6A-G-G haplotype has been the opposite (P< 0.01).

CONCLUSIONOur study has demonstrated that serum MMP-3 level is significantly increased at acute stage of LAA as well as SAO type strokes. There may be an association of rs3025058, rs522616 and rs679620 of MMP-3 gene with susceptibility to LAA stoke in northern Han Chinese population.
