Objective:To explore the quality of life and its influencing factors in patients with hyperthyroidism.Methods:From June 2017 to June 2019, patients with hyperthyroidism who were first diagnosed in the First Affiliated Hospital of Hainan Medical College were selected as the research objects, and the quality of life of the patients was assessed by the Chinese version of World Health Organization Quality of Life Brief Scale (WHOQOL-BREF). Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were used to evaluate the psychological status of the patients. Univariate analysis was used to compare the differences of general information (age, gender, course of disease, marital status, education level, occupation, monthly family income, family relationship, thyroid ophthalmopathy, laboratory examination, thyroid crisis, anxiety level, and depression level) among patients with different quality of life. Multivariate logistic regression analysis was used to analyze the related factors affecting the quality of life of patients with hyperthyroidism.Results:There were 120 patients, aged (45.42 ± 6.38) years old, including 42 males and 78 females. The WHOQOL-BREF score was (76.58 ± 10.42) points, ranging from 25 to 106 points. Among them, 49 cases (40.83%) had high scores (≥80 points) and 71 cases (59.17%) had low scores (<80 points). Univariate analysis showed that there were differences in the quality of life among different marital status, education level, monthly family income, family relationship, thyroid ophthalmopathy, FT 3, FT 4, anxiety level and depression level ( P < 0.05). Multivariate analysis showed that thyroid ophthalmopathy, divorce or widowhood, monthly family income < 2 000 yuan, family disharmony, depression or anxiety, abnormal FT 4 and FT 3 were the risk factors affecting the quality of life of patients with hyperthyroidism ( P < 0.05). Conclusion:The overall quality of life of patients with hyperthyroidism is low, especially those with thyroid ophthalmopathy, divorce or widowhood, monthly family income < 2 000 yuan, family disharmony, depression, anxiety, FT 4 or FT 3 abnormalities.

AIM: To observe the effect of osthole on tricalcium phosphate (TCP) particles-induced calvarial osteolysis in vivo.METHODS:Male ICR mice were randomly divided into sham group , TCP group and osthole group .A mouse calvarial model of osteolysis was established by TCP particles .On the second postoperative day , osthole (20 mg/kg) was locally injected into the calvarium under the periosteum 3 times a week.Two weeks after osthole treatment , blood and calvaria were collected to determine the level of bone turnover markers such as alkaline phosphatase ( ALP) , osteocalcin and tartrate-resistant acid phosphatase ( TRACP) .The periosteum was performed to examine the release of tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6) and IL-1βby ELISA.The calvaria was obtained for histological and molecular analyses.RESULTS:Data from HE and TRACP staining revealed that osthole prevented TCP particles-induced obvious increase in osteoclastogenesis and resorption area in the metaphysis of mouse calvaria .Osthole treatment increased ALP ac-tivity and osteocalcin level , and dncreased the activity of TRACP in the mouse serum compared with TCP group .Further-more, TCP particles-induced the releases of TNF-α, IL-6 and IL-1βwere significantly suppressed by osthole treatment .In addition, Western blot demonstrated that endoplasmic reticulum ( ER) stress markers such as glucose-regulated protein 78 (GRP78) and CAAT/enhancer binding protein homologous protein (CHOP) were significantly up-regulated in TCP parti-cles-implanted calvarial mice , indicating that TCP particles triggered an ER stress response in the mouse calvarial osteolysis model , which obviously attenuated by osthole .CONCLUSION:Osthole inhibits TCP particles-induced calvarial osteolysis in mice, which is mediated by inhibition of ER stress signaling pathway .

Objective:To study the drug resistance patterns of Bordetella pertussis in vitro, and to know the clinical characteristics of pediatric pertussis and evaluation the treatment outcomes, which may provide references for experiential diagnosis and treatment of this disease. Methods:Nasopharyngeal swabs of the hospitalized children with suspected pertussis in Children′s Hospital, Zhejiang University School of Medicine in 2017 were collected for culture. And the clinical data of the children were collected. The strains were identified by pertussis-specific antiserum agglutination and finally confirmed by mass spectrometry. The drug sensitivity test was performed using the E-test method. The efficacy of therapy with antibiotic was evaluated after two weeks of treatment. Statistical analysis was performed with Mann-Whitney U test and chi-square test. Results:Of 1 029 children, 211 (20.5%) nasopharyngeal swabs were positive for Bordetella pertussis culture, and the isolation rate of the specimens was highest (31.2%, 45/144) in July. Of the 211 pertussis patients, 105 (49.8%) were male and the age were 3.8 (2.2, 6.9) months, 114 (54.0%) were not vaccinated with pertussis diphtheria tetanus mixed vaccine and 192 (91.0%) were prescribed with previous antibiotics. There were 142 (67.3%) children from families with two or more than two children, and 136 (95.8%) of which were the youngest siblings. One hundred and fifty-nine (75.4%) patients had paroxysmal cough and 61 (28.9%) had whooping. The white blood cell counts were higher than 20×10 9/L in 94 (44.5%) patients, and the lymphocyte counts were higher than 10×10 9/L in 97 (46.0%) of patients. The drug susceptibility results showed that 138 (65.4%) strains were against erythromycin, azithromycin and clindamycin with minimum inhibitory concentration (MIC)>256.000 mg/L. The MIC 90 of the isolates to ampicillin, ceftriaxone, cefoperazone/sulbactam, meropenem and trimethoprim/sulfamethoxazole were 0.190 mg/L, 0.190 mg/L, 0.094 mg/L, 0.094 mg/L and 0.750 mg/L, respectively. All strains had a MIC of <0.016 mg/L for piperacillin/tazobactam. After treatment, symptoms were improved in 195(92.4%) patients when they were discharged from hospital. Seventy-six (57.1%) children whose symptoms did not improve after seven-day treatment with macrolides, were prescribed with other antibiotics or other antibiotic with macrolides in combination. Compared with the patients treated with macrolides, more patients treated with cefoperazone/sulbactam or piperacillin/tazobactam had negative nasopharyngeal culture results after two weeks of therapy (46/48(95.8%) vs 46/57(80.7%)), or on day seven (45/46(97.8%) vs 39/47(83.0%)) and on day 14 (45/45(100.0%) vs 41/47(87.2%)) since discharged. The differences were all statistically significant ( χ2=5.50, 5.86 and 6.15, respectively, P=0.019, 0.015 and 0.013, respectively). Conclusions:The majority of children with pertussis do not have whooping, and the resistant rate of Bordetella pertussis to macrolides is high. Further study is needed to evaluate the feasibility and reasonability of cefoperazone/sulbactam and piperacillin/tazobactam in treating pediatric pertussis caused by macrolides-resistant Bordetella pertussis.
