Objective To develop a new type of oxygen mask, which has adjustable vent and can be removable. Methods An adjustable and removable vent below the mask was added to the conventional mask, so the problem of taking off the mask for interrupted oxygen inhalation was solved. The change of the passage of the oxygen import and export could add comfort, keep away from the operation area of the neck,chest area, etc. The new mask had a filmy hole in each side which was for gastrointestinal drainage tubes,which increased tighmess. Results The new mask improved the effect of oxygen inhalation, added comfort to patients and was convenient for medical operation. Conclusions The mask is innovative and can be widely used in clinic.

Objective To determine the protein expression level of p-STAT1 and STAT1 in thyroid cancer and its correlation with clinical pathological parameters,especially with lymph node metastasis and relapse-free survival.Methods p-STAT1 and STAT1 protein were measured by immunohistochemical staining in 80 cases of primary thyroid carcinoma and matched normal controls.All samples were selected from the pathological storage in the Jiangdong 22nd Zone,of Zhuji People's Hospital.The correlation between p-STAT1,STAT1 and patients clinical pathological parameters was analyzed.74 out of 80 patients were followed up over 3 years to analyze the potential relationship between expression of p-STAT1 and STAT1 and relapse-free survival.Results The positive expression of p-STAT1 and STAT1 was 28.8％ and 90.0％ in thyroid cancer tissue versus 85.0％ and 50.0％ in normal thyroid tissue.The difference was statistically significant(P ＜ 0.05).The positve expression of p-STAT1 in stage Ⅲ and Ⅳ thyroid cancers was significantly lower than in stage Ⅰ and stage Ⅱ thyroid cancer(P ＜ 0.05).There was negative correlation between the expression of p-STAT1 and tumor stage and lymph node metastasis,while the expression of STAT1 was irrelevant.Furthermore,the relapse-free survival was 100％ in p-STAT1 positive patients,and 92.65％ in STAT1 positive group.Conclusion p-STAT1 protein level,negatively correlating with tumor stage and lymph node metastasis,down regulates in primary thyroid cancers,and may be a novel biomarker for thyroid cancer metatstasis.

Objective:To investigate the serum levels of soluble Fas (sFas) and soluble FasL (sFasL) in elderly patients with skin cancer and its clinical significance.Methods:Eighty-two elderly skin cancer patients who underwent surgical treatment in Zhuji People′s Hospital and Zhejiang Provincial People′s Hospital from January 2014 to December 2017 were selected as the skin cancer group, and 82 healthy elderly patients were selected as the control group. The serum sFas and sFasL levels were determined by double anti sandwich enzyme linked immunosorbent assay (ELISA).Results:The serum levels of sFas and sFasL in the skin cancer group were higher than those in the control group [(21.06 ± 3.23) μg/L vs. (5.64 ± 1.18) μg/L, (14.52 ± 3.42) μg/L vs.(3.27 ± 0.96) μg/L], there were significant differences ( t=40.606, 28.679, P<0.05). The serum sFas and sFasL levels were closely related to pathological grade and lymph node metastasis. The serum levels of sFas and sFasL in patients with pathological grade Ⅲ-Ⅳ were higher than those at grade Ⅰ-Ⅱ [(23.57 ± 3.16) μg/L vs. (16.35 ± 3.62) μg/L, (17.16 ± 3.29) μg/L vs. (12.15 ± 3.58) μg/L], there were significant differences ( t=8.931, 6.173, P<0.05). The serum levels of sFas and sFasL in patients with lymph node metastasis were higher than those without lymph node metastasis [(24.09 ± 3.46) μg/L vs. (14.37 ± 3.19) μg/L, (18.17 ± 3.64) μg/L vs. (11.02 ± 3.27) μg/L], there were significant differences ( t=13.124, 9.306, P<0.05). The serum sFas and sFasL levels were not associated with age, gender, location and type ( P>0.05). The serum sFas and sFasL levels after treatment were lower in patients with skin cancer than before treatment [(7.94 ± 1.21) μg/L vs. (21.06 ± 3.23) μg/L, (5.38 ± 1.02) μg/L vs. (14.52 ± 3.42) μg/L], there were significant differences ( t=34.445, 23.191, P<0.05). Conclusions:Serum sFas and sFasL levels are elevated in elderly skin cancer patients. The serum sFas and sFasL levels are closely related to pathological grade and lymph node metastasis in elderly skin cancer patients, and the clinical efficacy can be evaluated.

Objective:To provide reference for the development of a more intelligent and systematic nursing clinical decision support system based on the concept of precision nursing and data sharing, the nursing plan module of clinical decision support system.Methods:An evidence-based knowledge base was constructed based on the nursing process and the standardized nursing terminologies; the nursing plan module was designed according to clinical needs, and the logical reasoning rules were formulated from the generation, sequencing and stopping of nursing problems, objectives, measures and activities, and finally the nursing plan module of clinical decision support system was formed.Results:The nursing plan module of clinical decision support system included the basic information of patients, positive evaluation items and weight values, nursing problems, objectives, measures and activities, etc. the module could automatically deduce the nursing plan according to the patient's individual characteristic index (positive evaluation item), and sort the nursing problems and corresponding measures and activities according to the generation time, weight value and correlation degree. It could automatically distinguish nursing problems, goals, measures and the time of activity stop, and realize intelligent decision-making.Conclusion:The interface of nursing plan module of this system is clear and logical reasoning rules are rigorous. It breaks through the bottleneck of nursing decision-making based on personal professional knowledge and experience in clinical situation for a long time, which can ensure the homogeneity of nursing plan and improve the correctness of decision-making.

Objective:Iron accumulation is related to the occurrence of postmenopausal osteoporosis. Meanwhile, autophagy abnormality of bone marrow hematopoietic cells is observed in hip osteoporotic fracture. This study is performed to investigate correlation between iron accumulation induced bone loss and hematopoietic autophagy dysfunction to explore the new risk factor of osteoporosis.Methods:Male iron accumulation mice model was established by intraperitoneally injecting ferric ammonium citrate. Serum ferritin and osteogenic indicator P1NP were tested by ELISA. Bone mineral density was measured by micro-CT. Femur and tibia bone marrows were collected for hematopoietic stem and progenitor cells proportion and cell apoptosis analysis. Autolysosome formation was measured by image flow cytometry. We used conditional mouse model Atg7 flox/flox; Vav-Cre(Atg7 -/-) in which Atg7 had been genetically deleted in the hematopoietic system. Bone marrow hematopoietic stem and progenitor cells were collected for RNA sequence. micro-CT scan was conducted for Atg7 -/- femur. Results:Ferritin level of iron accumulation mice was significantly higher than control group( P<0.05). Iron accumulation inhibited P1NP and induced decreased bone mineral density( P<0.05). Iron accumulation bone marrow displayed enhanced hematopoietic stem and progenitor cells proportion( P<0.05), with more cell apoptosis( P<0.05). Hematopoietic autophagy was deteriorated in iron accumulation bone marrow. Transcriptomic profiling showed up-regulation of iron activity in Atg7 -/- mice, with increased iron homeostasis and iron membrane transporter genes, including Lcn2, Tfr2, Slc40a1(Fpn1), Steap3, and Cpox. micro-CT revealed severe bone loss and decreased bone mineral density in Atg7 -/- mice( P<0.05). Conclusion:Iron accumulation induced bone loss is related to inhibition of hematopoietic cells. Hematopoietic autophagy dysfunction is associated with bone loss.

Respiratory infectious disease has become ahead of all the children′s diseases, with the trend of continuously increasing global incidence, antimicrobial resistance and simultaneous infection with multiple pathogens. Diagnosis of this disease is mainly based on clinical symptoms and pathogenic detection. However, there are some differences in clinical manifestations, progression and prognosis between pediatric patients and adults, which prompting clinical diagnosis mainly depending on clinical laboratory test. Therefore, fast, convenient and accurate methods are urgently needed to clarify the type of infectious pathogen and carry out differentiated treatment, and reduce the burden on families and public health-care systems in schools. This article aims to elaborate the laboratory methods of children′s respiratory infectious diseases and explore the opportunities and challenges, which can provide ideas for prevention, early screening and diagnosis, prognosis and treatment monitoring.
