Objective To investigate the association of Galectin-3 ( lectin, galactoside-binding soluble , LGALS3)gene-191(rs4644)polymorphism and breast cancer in Chinese female population .Methods Galectin-3 gene rs4644 polymorphisms was genotyped by polymerase chain reaction-restriction fragment length polymor-phism(PCR-RFLP)in 172 breast cancer patients and 17 controls.The experimental results of PCR-RFLP were verified and sample of 10 cases were sequenced randomly .Results The frequency of CC ,CA and AA genotype in breast cancer group and normal control group was 72.7%, 25.0%, 2.3% and 52.9%, 41.2%, 5.9%, respectively .The frequency of C and A allele in breast cancer group and normal control group was 85.2%, 14.8%and 73.5%, 26.5% respectively .The genotype and frequency of allele had no statistical difference between breast cancer patients and the control group .rs4644C allele was more likely to occur in breast cancer patients with T>2 cm (χ2 =8.295,P=0.004) and Ki67<14%(χ2 =3.917,P=0.048).Conclusions There is no significant association between Galectin-3 gene 191 polymorphism rs4644 and susceptibility of breast cancer in Chinese female population .It is closely associated with the size of tumor and Ki 67.

Objective:To investigate the current situation of coping styles in Crohn's disease patients and its related influencing factors.Methods:A total of 80 patients with Crohn's disease admitted to our hospital from Apri 2021 to Dec 2022 were selected to evaluate their coping styles with a simple coping style questionnaire,and relevant data were collected.The factors affecting the coping styles of Crohn's disease were analyzed by multivariable logistic regression.Results:Among the 80 patients,29 cases were negative coping,the incidence was 36.25% .There were 51 patients with positive coping(63.75% ).Educational level,simplified Crohn's disease activity index(CDAI)score,adverse psychology,social support and type D personality were associated with negative coping(P＜0.05).Gender,age,family history,working status,monthly family income,place of residence,and marital status were not associated with negative coping in patients with Crohn's disease(P＞0.05).Multivariable logistic regression analysis showed that education level of high school or below(OR=2.945,95% CI:1.139-7.614),higher CDAI score(OR=11.999,95% CI:4.387-32.815),poor psychology(OR=5.950,95% CI:2.180-16.239),low social support(OR=3.598,95% CI:1.370-9.448)and type D personality(OR=3.208,95% CI:1.118-8.904)were risk factors for negative coping in patients with Crohn's disease(P＜0.05).Conclusions:The incidence of negative coping in patients with Crohn's disease is higher,which is related to high school education or below,high CDAI score,poor psychology,low social support,and type D personality.Therefore,clinical measures can be taken to promote patients to actively cope with the disease.
