ObjectiveTo explore the clinical application of ultrasound guided percutaneous right internal jugular vein catheterization in hemodialysis,and to analyze the methods,precautions and prevention of complications of puncture.MethodsTotally 297 patients of chronic renal insufficiency with uremia underwent ultrasound guided percutaneous right internal jugular vein catheterization according to technical points of increasing the success rate of puncture.ResultsThe total successful rate of puncture was 100％.The first puncture succeeded in 244 patients (244/297,82.15 ％),the second in 30 (30/297,10.10％) and the third in 23 (23/297,7.74％) patients.The complication rate was 15.15％ (45/297).Poor adherence of catheter led to cited blood difficultly and inadequate flow in 31 patients.ConclusionUltrasound guidance can greatly improve the success rate of puncture in percutaneous right internal jugular vein catheterization,while reduce the incidence of complications.

Objective To observe the effect of ear acupuncture point treatment for insomnia patients of kidney deficiency. Methods A total of 91 cases of insomnia patients with kidney deficiency were randomly divided into two groups: 46 cases of treatment group and 45 cases of control group. Patients in treatment group underwent ear acupuncture point treatment for 1 months, two ears in turn, three days changed. While patients in control group only used warm water treatment. Results The effective rate of treatment group was significantly higher than that in control group ( P < 0. 01). Except for sleeping efficiency and daytime function factor of PSQI factor score, the other score in treatment group was significantly lower than that in control group (P < 0. 05). The SAS score of treatment group had significant difference, (P <0. 01). There was no significant difference in terms of the rate of adverse effect between groups (P >0. 05); The positive symptom of anxiety and depression in treatment group was significantly lower than that in control group. Conclusions The effect of ear acupuncture point treatment can improve sleep quality and psychological health of patients of kidney deficiency, its uncomfortable rates has no significant difference compared with that in hot water footbath therapy.

To determine cancer pathway activities in nine types of primary tumors and NCI60 cell lines, we applied an in silico approach by examining gene signatures reflective of consequent pathway activation using gene expression data. Supervised learning approaches predicted that the Ras pathway is active in ～70% of lung adenocarcinomas but inactive in most squamous cell carcinomas, pulmonary carcinoids, and small cell lung carcinomas. In contrast, the TGF-β, TNF-α, Src, Myc, E2F3, and β-catenin pathways are inactive in lung adenocarcinomas. We predicted an active Ras, Myc, Src, and/or E2F3 pathway in significant percentages of breast cancer, colorectal carcinoma, and gliomas. Our results also suggest that Ras may be the most prevailing oncogenic pathway. Additionally, many NCI60 cell lines exhibited a gene signature indicative of an active Ras, Myc, and/or Src, but not E2F3, β-catenin, TNF-α, or TGF-β pathway. To our knowledge, this is the first comprehensive survey of cancer pathway activities in nine major tumor types and the most widely used NCI60 cell lines. The "gene expression pathway signatures" we have defined could facilitate the understanding of molecular mechanisms in cancer development and provide guidance to the selection of appropriate cell lines for cancer research and pharmaceutical compound screening.

In order to analyze the expression of genes involved in steroidal saponin biosynthesis pathway in Polygonatum cyrtonema tubers, it is very important to select internal reference genes that are stably expressed at different development stages and in response to abiotic stress. According to the previously established P. cyrtonema transcriptome database and reported internal reference genes in plant, this study systematically analyzed eight candidate internal reference genes including histone H2 A, glyceraldehyde-3-phosphate dehydrogenase, ACTIN, β-tubulin, ubiquitin-conjugating enzyme-E2-10, elongation factor 1-alpha isoform, 18 S rRNA and α-tubulin 4 for expression stability in P. cyrtonema tubers at different development stages and in response to methyl jasmonate(MeJA) stress by using Real time fluorescence quantitative PCR(qPCR). Based on the statistical analysis of qPCR results by using GeNorm, NormFinder and BestKeeper softwares, the expression of ubiquitin-conjugating enzyme-E2-10 and elongation factor 1-alpha isoform are the most stable in P. cyrtonema tubes at different development stages and in response to MeJA stress. The two internal reference genes were further validated by analyzing the expression of 4 genes involved in steroidal saponin biosynthesis pathways. In conclusion, ubiquitin-conjugating enzyme-E2-10 and elongation factor 1-alpha isoform can be used as the most appropriate internal reference genes for qPCR analysis in P. cyrtonema. This study also provide a foundation for future investigate the molecular mechanism of steroidal saponin biosynthesis pathways in P. cyrtonema.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.
