Objective To study clinical effects of lavage treatment for inflammatory breast diseases guided by color Doppler sonography.Methods The lesions of 63 patients with inflammatory breast diseases (30 of breast abscess,20 of plasma cell mastitis,13 of breast chronic sinus)were positioned by color Doppler sonography.Surgical debridement and lavage catheter treatment were performed under general anesthesia.Results 54 patients were healed by first intention,and they were satisfied with their breast shapes.4cases of mammary abscess,3cases of plasma cell mastitis and 2 cases of breast chronic sinus had relapse within half a month.Conclusions Color Doppler sonography guided lavage treatment of inflammatory breast diseases is simple with significant healing effect,fast recovery speed,less recurrence and high cure rate.The operation had little pain to patients and small hidden postoperative scar.The breast shapes are nice-looking.

OBJECTIVETo investigate the therapeutic effect of reconstruction of facial defects with frontal expanded flaps bipedicled by superficial temple vessels and supraorbital/supratrochlear neurovascular bundles.

METHODSFrom June 2006 to Mar. 2013, the patients with mostly unilateral facial defects which affected temple area and crossed the facial midline, were treated with frontal expanded flaps. The expanders were implanted at first stage and the expanded frontal flaps were transferred at second stage. At third stage, pedicle division was performed and the pedicle skin tissue was used to repair the residue defect.

RESULTAll the 18 flaps survived completely with satisfactory color and texture. Good results were achieved during the follow-up period of one year.

CONCLUSIONThe bipedicled frontal expanded flap has a reliable blood supply which is very suitable for large facial defect.

OBJECTIVE: In order provide important evidences for epidemiologic survey, clinical diagnosis, treatment and preservation of allergic diseases in this area, we investigate the distribution of the common allergens in allergic rhinitis and allergic asthma in Jingmen area and the sensitization condition of the major allergen house dust mite. METHOD: Four hundred and twenty-five patients with suspected allergic rhinitis and asthma in our area accepted skin prick tests of 10 standard allergen agents and specificity IgE detection. The different positivity ratios of allergens in different age groups were compared and the correlation between the two different technique methods testing the dust mite allergen was analyzed. RESULT: Among 425 patients with suspected allergic rhinitis and asthma in our area, 298 patients were positive and 89 patients suffered a combined allergic asthma. House dust mite (292 cases) and dermatophagoides farinae (289 cases) were the commonest allergens. The other common allergens were mugwort (45), ragweed (31), fungus I (19), fungus II (15), spring-pollen II (14), poly-animal hair (14), spring-pollen I (9), poly-feather (3). There was a correlation between skin test and sIgE test for house dust mite, dermatophagoides farinae in children group, and the positivity ratios were significantly higher than the adults group. CONCLUSION Dust mite is the most important allergen in allergic rhinitis and asthma in Jingmen.

OBJECTIVE: To investigate the profiles of inhaled allergens in allergic rhinitis patients in district of Jingmen, and to provide basic epidemiologic information for the prevention and treatment of allergic rhinitis in this area. METHOD: Retrospectively analyze 10 allergens skin prick test results of 1800 allergic rhinitis patients recruited. RESULT: The most common inhaled allergens in allergic rhinitis patients in our area were house dust mite (76.83%), dermatophagoides farinae (75.50%), mugwort (10.50%), ragweed (7. 39%), fungus II (6.28%), fungus I (5.83%), spring-pollen I (4.44%), spring pollen II (3.72%), poly-animal hair (3.56%), poly-feather (1.89%). Moreover, the positivity frequencies of house dust mite and dermatophagoides farinae were decreased with age increasing. CONCLUSION House dust mite and dermatophagoides farinae were the most common allergens in allergic rhinitis patients in Jingmen area.

Objective: To understand the current situation and differences in physical activity among children and adolescents in different regions of China, so as to provide a scientific reference for promoting the level of overall physical activity promotion among children and adolescents in China. Methods: From June to December 2023, the student satisfaction assessment questionnaire for the national children and adolescents theme fitness activity "Run, Youth!" was conducted, which was administered via a combined online and offline questionnaire survey to explore 397 013 students participation in the "Run, Youth!" activity in 2023. Descriptive statistics, Logistic regression, and other approaches were utilized for data analysis. Results: There were notable disparities in the rates of children and adolescents meeting the physical activity standards among northeast China, northwest China, north China, east China, central China and southwest China (10.27%, 11.79%, 9.32%, 8.48%, 8.81%, 7.30%) ( χ 2=33.48, P <0.05). The results of multivariate Logistic regression analysis showed that rate of recommended level of physical activity among children in northwest China, boys, children aged 16-18, children in urban areas were relatively high ( OR =1.12, 1.68, 0.60, 1.88, P < 0.05 ). After adjusting for confounding factors, the results of binary Logistic regression analysis showed that there was an interactive effect relationship between the interaction of region, age, gender, and urban-rural distribution and physical activity among children and adolescents ( OR=0.51, P <0.01). Based on gender analysis, weekly physical activity duration of boys in each region surpassed that of girls; based on age analysis, except for the central and southwestern regions, weekly physical activity duration of children and adolescents gradually increased with age in other regions; based on the proportion of urban and rural areas, weekly physical activity duration of children and adolescents in urban areas across all regions exceeded that in rural areas. Conclusions The attainment rate of sufficient physical activity among children and adolescents in northwest China is the highest, and the differences between regions are not significant. The participation and level of physical activity of male students in each region surpass those of females and the attainment rate of physical activity of physical activity of urban children and adolescents is higher than that of those in rural areas.

OBJECTIVE: To screen the differentially expressed proteins at the early stage of K562 cells treated with meisoindigo by using tandem mass tags (TMT)-based proteomics technology, and to explore the mechanism for meisoindigo-inducing apoptosis. METHODS: The half inhibitory concentration (IC) of mesoindigo on K562 cells was determined by CCK8. The flow cytometry was used to assay the apoptosis of K562 cells treated by meisoindigo or DMSO. Total proteins were extracted from the cells treated with 0.2% DMSO (control) or 20 μmol/L meisoindigo (Test) for 2 hours. Then, the TMT-labeling HPLC-MS/MS was used to identify and quantify the peptides and their abundance, all the tests were repeated for 3 times. The Mascot software was used to identify the proteins; the GO annotations, enrichment and cluster analysis were used to analyze the differentially expressed proteins. RESULTS: Meisoindigo-induced K562 cell apoptosis in a dose-dependent manner (r=0.98), 5 544 proteins were identified, 4792 of which were quantified. The protein with expression difference>1.5-folds in Test group accoanted for 8, out of which the expression of 4 proteins were up-regulated and 4 were down-regulated. The differentially expressed proteins mainly associated with reactive oxygen species (ROS). CONCLUSION Several proteins including DDIT4 were found to have dramatic changes in the early stage of K562 cells treated with meisoindigo by using quantitative proteomics technology. The ROS metabolic process may play important roles in meisoindigo-inducing apoptosis of K562 cells.
