目的 分析乳腺恶性肿瘤患者的诊断和治疗方法的动态变化,了解该疾病的患者诊治相关行为方式的变化。方法 抽取我院1999年—2014年收治的所有乳腺恶性肿瘤患者,比较不同初诊时间和初诊年龄分组间,患病部位、肿瘤大小、手术方式、治疗方式的差异。结果 比较1999年—2004年组、2005—2009年组,近年诊断的肿瘤最大直径有所下降,经过卡方比较,构成比有差异(χ²=14.2,P=0.007)。近年诊断的患者更愿意选择积极的改良根治术作为手术治疗方式(χ²=38.8,P<0.001)。就不同年龄而言,年轻的患者选择改良根治术和化疗的比例也较年老的患者高,而年龄大的患者则选择姑息治疗的比例较高(χ²=154.9,P<0.001)和(χ²=129.8,P<0.001)。结论 乳腺恶性肿瘤的认知的加强,诊治技术的提高,乳腺恶性肿瘤能够更早的被发现诊断,治疗方式的选择也更加积极。

Objective To analyze the dynamic changes of breast cancer diagnosis and treatment. and to understand the changes of related behaviors of the patients. Methods From 1999 to 2014, breast cancer patients were chosen, the differences of tumor size, operation and treatment were not compared. Results The results were compared within different groups of diagnosis years, such as 1999-2004,2005-2009, and 2010-2015. The maximum diameter of the tumor diagnosed in recent years was decreased, χ²=14.2,P= 0.007. At the same time, patients that were diagnosed in recent years were more likely to choose radical surgery as surgical treatment, χ²=38.8,P<0.001. Comparing within groups of different ages, more patients chose radical surgery and chemotherapy in younger patients than older ones, we found that the older patients chose a higher proportion of palliative care, χ²=154.9,P<0.001 and χ²=129.8,P<0.001. Conclusion Understan-ding of breast cancer malignancies was enhanced. Breast cancer may be diagnosed earlier and the choice of treatment is more positive with the development of technology.

Objective To investigate the distribution and drug resistance of pathogenic bacteria in diabetic foot wounds in Guangdong area. Methods Patients with diagnosis of diabetic foot between group A (from Jan 2010~Dec 2014 ) and group B (from Jan 2015 to Jan 2018) were retrospectively analyzed. We studied the bacteria distribution and drug resistance of pathogenic changes of group A and group B. Results In group B, both G+ and G- bacteria had a decreased trend while G- bacteria decreased rapidly, but the species of bacteria increased obviously just as fungi and mixed infection increased obviously. Bacteria infection in group A were mainly about Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli wihle group B were Staphylococcus aureus, Proteus mirabilis, Aeruginosa and Fungal infection; the resistance of group B to A was lower. Conclusion In recent years, kinds of pathogenic bacteria of diabetic foot were significantly increased and the mixed infection and increased fungal infection as well as its drug resistance increased, so the early experience of medication choice of antibiotics based on drug sensitivity and treatment are the key to the treatment of diabetic foot infection.

Results Compared with healthy control group,TSH、FT4、TT4、FTS、TT3 level in non-ARDS group has no statistical difference(P＞0.05),while compared with the rest of the two groups,all indexes in ARDS group were lower (P＜0.05). And TSH、FT4、TT4、FT3、TT3 levels in moderate ARDS group decreased compared with those in relatively mild ARDS (P＜0.05). The level of each index in severe ARDS group decreased compared with the moderate ARDS group (P＜0.05). There was statistical difference in detection index level in three groups. Conclusion The serum thyroid hormone level of ARDS patients is positively correlated with hypoxemia. As the pathological severity changes ,the level of hypoxemia changes are more apparent. Dynamic monitoring of serum thyroid hormone is of great significance in severity judgement and prognosis evaluation.

Objective To establish a model of acute inhalation injury in dogs, and to investigate the changes of vital signs in the early stage of acute inhalation injury and the correlation between cardiac output (CCO), cardiac output index CI), stroke volume variability (SVV) and other core hemodynamic variables. Methods The animal models of inhaled lung injury were established. The animals were randomly divided into four groups: control group (no injury); Lung edema group: according to the observation time of lung injury after lung injury, they were divided into B1 group: 1 h; B2 group: 2 h and B3 group: 4 h. The hemodynamic indexes such as ABP, SVV and CO were monitored. Results The changes of circulatory kinetics occurred in the early stage of the injury after aspiration of canine vapor inhalation, which was most obvious in 30 minutes to 1 hour after injury. The levels of ABP, HR, CO were decreased and SVV was increased. Conclusion Inhalation of lung injury in dogs after inhalation, early changes in the occurrence of circulatory dynamics occured, resulting in animal oxygenation and metabolic disorders, and these can quickly lead to pulmonary edema, so that 30 minutes to 1 hour after injury, hemodynamic chcnge were the most obvious.

Objective To investigate the correlation between change characteristics of pregnant genital tract flora and adverse pregnancy outcomes. Methods 90 pregnant women received routine obstetric examination in our obstetrics and gynecology of hospital from January 2015 to September 2015 were selected as research object. According to duration of pregnancy, they were divided into 28 cases of early pregnancy group (gestational weeks<14 weeks), 29 cases of middle pregnancy group (14~28 weeks) and 33 cases of late pregnancy group (29~42 weeks). The vaginal or cervical secretions were collected, and genital tract flora was detected. The genital tract flora distribution of three groups were compared. According to bacteria detection results, patients were divided into 44 cases of positive group and 46 cases of negative group. The adverse pregnancy outcomes of two groups were observed, and the correlation between change characteristics of pregnant genital tract flora and adverse pregnancy outcomes was analyzed. Results Among 90 pregnant women, there were 44 cases of positive bacteria (48.89%), which included 20 cases of ureaplasma urealyticum(45.45%), 9 cases of Candida (20.45%), 8 cases of enterobacter (18.18%), 3 cases of staphylococcus (6.82%), 2 cases of vaginal gardnerella (4.55%) and 2 cases of chlamydia (4.55%); There was no statistical difference in the genital tract flora distribution among early, middle, late pregnancy group (P>0.05); The incidence of premature rupture of membrane, puerperal infection, neonatal infection and premature birth in patients with positive bacteria was higher than that in patients with negative bacteria (P<0.05); There was no statistical difference in the adverse pregnancy outcomes in patients with different types of bacterial genus (P>0.05). Conclusion Pregnant genital tract flora are mainly ureaplasma urealyticum, candida and enterobacter, and the incidence of adverse pregnancy outcomes in patients with positive bacteria is higher, but different types of bacterial genus has no correlation with adverse pregnancy outcomes.

目的 探讨系统性红斑狼疮(SLE)患者外周血中25-羟基维生素D(25-OH-D)和白介素-17(IL-17)水平的变化及其临床意义。方法 选取40例SLE患者作为研究对象, 20例健康体检人员为健康对照组。运用电化学发光法检测25-OH-D水平,酶联免疫吸附法检测IL-17水平。结果 SLE患者25-OH-D水平明显低于健康对照组(P<0.01),活动期SLE患者25-OH-D水平明显低于缓解期患者(P<0.01)。SLE患者IL-17水平明显升高(P<0.01)。低25-OH-D水平与肾损害(P<0.01)相关,与疾病活动度评分(SLEDAI评分)(r=-0.844,P<0.01)及IL-17水平(r=-0.596,P<0.01)负相关。结论 SLE患者25-OH-D水平降低,低25-OH-D水平与肾损害、病情活动及高IL-17水平相关,25-OH-D可能参与了SLE的炎症进程。

Objective To assess the 25-hydroxyvitamin D (25-OH-D) and interleukin-17(IL-17) status in patients with systemic lupus erythematosus(SLE) and its clinical significance. Methods 40 SLE patients along with 20 matched controls were collected. Chemilumineseent immunoassay (CLIA) was used to detect the levers of serum 25-OH-D. The levels of serum IL-17 were evaluated using enzyme-linked immunosorbent assay (ELISA). Results Serum 25-OH-D level in SLE patients was significantly lower than in healthy controls (P<0.01). Serum 25-OH-D level in active SLE patients was significantly lower than in inactive SLE patients (P<0.01). Lever of IL-17 was significantly higher in SLE patients than in healthy controls (P<0.01). Insufficiency of 25-OH-D was related to renal disorders. Serum 25-OH-D level was negatively correlated with systemic lupus erythematosus disease activity index (SLEDAI) scores(r=-0.844, P<0.01)and serum levels of IL-17(r=-0.596, P<0.01). Conclusion Insufficiency of 25-OH-D is prevalent in SLE patients. It is associated with nephritis, disease activity and high serum levels of IL-17, thus it may play an important part in the inflammatory process in SLE.
