Objective To study the effect of the toothpaste containing FE enzyme on oral care to for critically ill patients with stroke. Methods Sixty cases of critically ill stroke patients were randomly divided into the experiment group and the control group with 30 cases in each group.The toothpaste containing FE enzyme was used in experiment group for oral care,and the routine oral care was used in the control group.The two groups were compared in terms of the oral cleaning effect,dental plaque and costs for the oral care.Results The incidences of bad breath,oral uncleanness and oral infection were significantly lower than those of the control group(P<0.01 or P<0.05). The dental plaque index after oral care was significantly lower in the experiment group than that in the control group(P<0.001).The cost in the experiment group was significantly lower than that in the control group(P<0.01).Conclusion Oral care using toothpaste containing FE enzymecan not only achieve an effective oral cleaning purpose,but also reduce the cost of oral care.

Objective To explore the value of echocardiography in evaluation of pulmonary venous in total anomalous pulmonary venous connection (TAPVC).Methods Fifty-five children with TAPVC were enrolled in the study.The data of echocardiography and CT angiography were retrospectively analyzed and compared with intraoperative findings.Results Totally 55 patients with TAPVC were classified into supra-cardiac type (n=24),cardiac type (n=20),infra-cardiac type (n=7) and mixed type (n=4) according to the sites of drainage of pulmonary venous in echocardiography.In 15 patients with obstruction of pulmonary vertical vein,the sites of obstruction in the supra-cardiac type mostly presented between vertical vein and superior vena cava or innominate vein,and the sites of obstruction in the infra-cardiac presented all between vertical vein and hepatic or portal vein.In 4 patients with pulmonary vein stenosis,3 cases with local pulmonary vein stenosis were all cardiac type,which presented between individual pulmonary vein and common confluence or right atrium;1 patient with diffuse pulmonary vein stenosis was infra-cardiac type.In 9 patients of abnormal individual pulmonary vein,8 cases were not detected by echocardiography,but all were detected by CT angiography.Conclusion Echocardiography is able to make more comprehensive evaluation for the pulmonary venous drainage,obstruction,and proximal stenosis of individual pulmonary vein in TAPVC.CT angiography is superior in evaluation of abnormalities of connection and amount of individual pulmonary vein,and imaging of distal pulmonary vein.

Objective To study the surface electromyographic signal characteristics of submental and infrahyoid muscles when swallowing in patients with nasopharyngeal carcinoma (NPC) following radiotherapy.Methods Fifteen post-radiotherapy NPC patients with pharyngeal dysphagia confirmed by videofluoroscopie swallowing study (VFSS) were selected into the patient group,while another 15 healthy subjects were recruited into the healthy group.Surface electomyography (sEMG) was used to collect sEMG signals from submental muscles and infrahyoid muscles during both dry and 3 ml thick liquid swallowing,and sEMG duration,average amplitude and peak amplitude parameters were compared between the two groups.Results Compared with healthy subjects,the patient group showed significantly longer sEMG duration of submental muscles and infrahyoid muscles during dry swallowing and 3 ml thick liquid swallowing (P＜0.05).Moreover,significantly longer sEMG duration of submental muscles and infrahyoid muscles was observed when swallowing 3 ml thick liquid,compared with dry swallowing (P＜0.05).The average sEMG amplitude and peak amplitude of submental muscles and infrahyoid muscles of patients when dry swallowing and 3 ml thick liquid swallowing were both significantly higher than those of healthy subjects (P＜0.05).Conclusion Submental muscles and infrahyoid muscles manifested enhanced contractions during swallowing in NPC patients with dysphagia,which played a compensatory role after radiotherapy.

Triple positive breast cancer overexpress ER (estrogen receptor), PR and HER2 (human epidermal growth factor receptor 2, HER2), accounting for about 50%-60% of the HER2 positive breast cancer patients. Based on the data from clinical trials, the crosstalk between the ER signaling pathway and the HER2 signaling pathway in triple-positive breast cancer may weaken the efficacy of anti-HER2 therapy and endocrine therapy, and this feature has attracted widespread attention. Emerging evidence shows that while blocking HER2 signaling pathway, together with enhancing blocking of ER signaling pathway, such as anti-HER2 dual-targeting + endocrine therapy ± CDK4 / 6 inhibitors, could effectively overcome drug resistance, and improve the efficacy. Predictive biomarkers including Ki67, intrinsic subtypes, and multi-gene assay, which have the potential benefit for personalized treatment.

Objective:To explore the current status of HBV infection before pregnancy among rural childbearing age people in Yunnan province, find out the population at high risk and areas with high incidence and provide evidence for promoting pre-pregnancy aristogenesis and medical interventions for prevention of HBV infection.Methods:The subjects in the study were rural childbearing age people aged 18-49 who received the national free pre pregnancy eugenic health examination in Yunnan province during 2013-2017. Descriptive analysis was conducted for HBsAg positive rate and its difference among various characteristics. The SPSS 22.0 software was used for statistical analysis.Results:A total of 2 180 841 rural childbearing age people were surveyed, the HBsAg positive rate before pregnancy was 3.13%(68 314/2 180 841) in Yunnan. And the HBsAg positive rate was 3.56% (37 694/1 057 376) in men, higher than that in women (2.73%, 30 620/1 123 465). The HBsAg positive rate was highest in age group 41-49 years (3.77%, 3 126/82 931). The HBsAg positive rate was higher in minority ethnic group (3.77%, 27 974/742 518) than in Han ethnicity group (2.81%, 40 024/1 425 870). Moreover, the highest HBsAg positive rate of was 8.20%(851/10 378) in Yao ethnic group. The people with education level of primary education had the highest HBsAg positive rate (3.97%, 17 294/435 219). The HBsAg positive rate was highest in Xishuangbanna Dai autonomous prefecture (6.65%, 3 875/58 232) in Yunnan. Moreover, the HBsAg positive population in severe poor area (3.32%, 19 755/595 665) was higher than those in less poor area (3.17%, 29 750/939 101) or normal areas (2.91%, 18 809/646 075). There was significant difference in HBsAg positive rate among populations in different age groups, ethnic groups, education level groups, areas and economic level groups ( P<0.001). Conclusions:The HBsAg positive rate in rural childbearing age people in Yunnan was related to multi factors, including sex, age, ethnic group, education level, area and economic development level. The HBsAg positive rate was higher in men, older age and lower education level, minority ethnic group (especially in Yao ethnic group), from Xishuangbanna prefecture and the poor living conditions in childbearing age population.

Objective:To determine the prevalence, epidemiological characteristics, and related factors of syphilis infection among rural childbearing age people to promote medical interventions on pre-pregnancy aristogenesis and syphilis infection in Yunnan province.Methods:The subjects in this study were 18-49-year-old rural couples of childbearing age from the National Free Preconception Health Examination Project in Yunnan province during 2013-2017. The descriptive study was carried out to determine the positive rate of Treponema pallidum specific antibody (TPsAb) and related sociodemographic characteristics. Results:The overall positive rate of TPsAb was 0.38% (8 204/2 160 455) in 2 160 455 rural childbearing age people in Yunnan. The positive rate of TPsAb was 0.39% (4 019/1 040 981) in men,higher than that in women (0.37%,4 185/1 119 474). The positive rate of TPsAb was highest in the age group 45-49 years (0.70%,158/22 511). The positive rate of TP antibody in the minority ethnic groups and Han ethnic groups appeared the same (0.38%). However,the highest positive rate of TPsAb was 0.77% (461/60 153) in Hani ethnic group among all the 17 minority ethnic groups. People with education level of primary education had the highest anti-TP positive rate (0.54%,2 327/431 275). The positive rate of TPsAb appeared the highest in Zhaotong (0.73%, 2 049/281 614) area among all the 16 prefectures of the province. The positive rate of TPsAb in the population from the impoverished regions (0.50%,2 963/590 039) was higher than in other disadvantaged areas (0.34%, 3 115/929 368) or areas with average income (0.33%,2 126/641 048). Significant differences appeared in the positive rate of TPsAb among populations of different ages, ethnic, education level, and economic level groups (trend χ2 test, P<0.001). Conclusions:The positive rate of TP antibody in rural childbearing age people in Yunnan was related to multi factors,including sex,age,ethnic group,education level,area, residence, and local economic situation. The positive rate of TPsAb was higher in men than in women. And people with elder age, lower education level, being Hani or Lahu ethnic group, and Zhaotong areas had higher TPsAb positive rates and higher syphilis infection risk.
