Objective:To investigate the interpersonal attribution style,self-efficacy of the baccalaureate female nurs-ing students(BFNS) and to explore the relationship between attribution style and self-efficacy.Methods:113 BFNS from Hainan Medical College were investigated by the Interpersonal Relationship Subscale of Multidimensional-Multiattribu-tional Causality Scale by Lefcourt et al and the General Self-Efficacy Scale(GSES) by Ralf Sehwarzer.Results:The Inter-personal Relationship Attribution Score(IRAS) of BFNS was 41.02?11.38.There was no statistical difference in IRAS be-tween two grades(t=0.899,P=0.371).The BFNS's attribution sequence was ranked as effort,fortune,ability,and back-ground under the condition of interpersonal communication success;while it was fortune,ability,effort,background under the condition of failure.There was statistically significant difference between scores of GSES and the normal(t=-10.212,P= 0.000).Pearson correlation analysis showed that there were positive correlations between the self-efficacy and interperson-al attribution style.Conclusion:When the female nursing students' behavior is successful,there is show more tendency to internal attribution.On the contrary,when they fail,there is more tendency to external attribution.Self-efficacy interacts with interpersonal attribution style.

Objective: To establish a female SPF BALB/c mouse model of antibiotic-associated intestinal microflora disturbance and analyze the effect of lactobacillus acidophilus.Methods: Female SPF BALB/c mice were treated with ceftriaxone in drinking water for five days,and followed by oral gavage of sodium chloride as natural recovery group or lactobacillus acidophilus(108CFU/mL) as therapeutic group.After seven days the intestinal microflora of the cecum content was abstracted and computed by plate counts and 16S rDNA-based PCR-DGGE method.Results: Plate counts indicated that the number of original bacterium lacticum and bacillus bifidus decreased significantly and enterococci proliferated abnormally after antibiotic treatment.After lactobacillus acidophilus treatment,the number of physiological bacteria and enterococci go back to normal levels.DGGE profile clearly indicated that the dominant bacteria changed and the bacterial diversity of intestinal microbiota was obviously decreased in the antibiotics treated group. Conclusion: Oral gavage of lactobacillus acidophilus has adjustment effect on Ceftriaxone induced intestinal microbiota disturbance.PCR-DGGE is a rapid、effective molecule method to reveal the whole microbiota status.

Objective To explore the symptoms of anxiety,family structure,and the distribution features of family about in-patients.And to find out the influence of the family structure on in-patients' symptoms of anxiety.The results would provide evidentiary support and suggestions for in-patients to improve quality of life and for prevention and intervention of anxiety.Methods Family table was used to register the family structure which was classified as the nuclear family,stem/expended family and other classification.The anxiety of in-patients was measured by self-rating anxiety scale.Results A total of 512 cases of in-patients completed the survey,there were 483 valid questionnaires.The rate of effective questionnaire was 94.34％.In family structure of in-patients,core family accounted for 48.65％,stem/expended family was 36.85％.The sex of family structure showed significant difference,the female proportion of the nuclear family was significantly higher than male.Among all in-patients,78.05％ did not have anxiety,low-level,medium-level,and severe anxiety showed no significant differences.The effects of anxiety on family structure had significant differences.The anxiety level of stem family was relatively higher.Conclusions Economic development and the population flow due to industrialization and globalization changed family structure of our country,especially in coastal de-velopment cities with fast economic development,fast-paced and stressful work,and it may affect the influ-ence of Chinese traditional family structure on anxiety of the in-patients.

The expressions of NF-κB and PPARγ were increased in adipose tissue of insulin resistant rats.The angiotensin receptor blocker decreased NF-κB protein expression by 21%,increased PPARγ protein expression by 28%and diminished adipocyte size,suggesting that these findings may be involved in the improvement of obesity-induced inflammation and insulin resisitance.

Objective: To investigate the prevalence and influencing factors of menopausal syndrome among postmenopausal women in Pan'an County, Zhejiang Province, so as to provide the basis for guiding the health management of postmenopausal women. Methods: From May 2023 to April 2024, the postmenopausal women aged 40 to 69 years in Pan'an County were selected using the random cluster sampling method. Demographic information, lifestyle and prevalence of gynecological diseases were collected through questionnaire surveys. The prevalence of menopausal syndrome was assessed by modified Kupperman Score Scale. Factors affecting menopausal syndrome were analyzed by a multivariable logistic regression model. Results: A total of 816 postmenopausal women were surveyed, with an mean age of (57.63±2.92) years and a mean natural menopause age of (49.85±2.13) years. There were 574 cases with menopausal syndrome, with a prevalence of 70.34%. Flashes and sweating, insomnia and irritability were common symptoms, accounting for 62.87%, 47.43% and 41.18%, respectively. Multivariable logistic regression analysis showed that monthly personal income of ≤5 000 yuan (<3 000 yuan, OR=3.124, 95%CI: 1.829-5.335; 3 000-5 000 yuan, OR=2.399, 95%CI: 1.370-4.201) and having gynecological diseases (OR=1.970, 95%CI: 1.292-3.004) were associated with a higher risk of menopausal syndrome, while average (OR=0.141, 95%CI: 0.072-0.276) or sufficient sleep quality (OR=0.095, 95%CI: 0.049-0.185) were associated with a lower risk of menopausal syndrome. Conclusion The prevalence of menopausal syndrome among postmenopausal women in Pan'an County is relatively high, and is mainly influenced by personal economic status, sleep quality and the presence of gynecological diseases.

Studies have found that obesity is not only closely related with the occurrence and development of breast cancer,but also can significantly increase the risk of breast cancer recurrence and death,especially the occurrence of postmenopausal estrogen receptor positive breast cancer.Therefore,it is of great importance to understand the influence of obesity on the prognosis of breast cancer.The intervene of diet and lifestyle,metformin and other drags,and other obesity targeted therapies have provided direction for future research on these influence.

OBJECTIVE: To study the molecular pathogenesis of SLC26A4 mutations associated with inner ear malformations including large vestibular aqueduct syndrome (LVAS), Mondini dysplasia and inner ear malformations but not accompanied with LVAS. METHOD: DNA sample and clinical material were obtained from 14 sporadic LVAS probands, six Mondini dysplasia probands and seven inner ear malformations excluding IVAS probands. SLC26A4 gene mutation was analyzed by direct sequencing for its 20 coding exons. GJB2 gene and also mt12SrRNA were analyzed by direct sequencing. RESULT: In 14 cases of LVAS, two mutations were detected in 12 patients (85.7%, either homozygous or compound heterozygous mutations), and one mutation was found in two patients (14.3%). In six cases of Mondini dysplasia, two mutations were detected in all of patients (100%). No mutation could be found in the seven cases of other inner ear abnormalities not accompanied with LVAS. No pathogenic mutation was detected in all of these 27 probands in GJB2 gene and mt12SrRNA 1555/1494T. CONCLUSION We have shown that LVAS and Mondini dysplasia closely correlate with SLC26A4 gene. No mutation was detected in seven probands of inner ear malformations not accompanied with LVAS. We should study the molecular pathogenesis of this disease in depth.

OBJECTIVETo identify the mutation of the autoimmune regulator gene (AIRE) in a Chinese family with autoimmune polyendocrinopathy syndrome type I (APS-I).

METHODSThe AIRE gene mutations were detected using PCR and direct DNA sequencing. Restriction enzyme analysis was used to confirm the mutations and bioinformatic methods were used to predict the possible impact of the mutations on the structure and function of the AIRE protein.

RESULTSA compound heterozygous mutation of A19T/R257X was detected in the proband. Her father had the A19T mutation in exon 1, but this mutation was not detected in 100 unrelated healthy individuals. Her mother had the R257X mutation in exon 6.

CONCLUSIONThis is the first report about AIRE mutations in Chinese APS-I kindred. The A19T mutation identified in this study has not been reported in the human gene mutation database (HGMD); the R257X has not been reported in Asians.
