Effects of remote team nursing support on patients with brain tumor in release their negative emotions and improve their quality of life / 中国实用护理杂志

Objective To explore the effect of nursing support on negative emotion and quality of life in patients with brain tumor. Methods A total of 139 cases of brain tumor in Shandong Provincial Cancer Hospital of Shandong University from September 2014 to February 2016 by convenient sampling , according to the random number table, they were divided into the control group and the intervention group. The patients in the control group were given routine discharge follow-up, while the patients in the intervention group were given emote team nursing support on the basis of the control group. We used anxiety self rating scale (SAS), depression self rating scale (SDS) and quality of life assessment scale (QLICP-BN) evaluation two groups of patients with anxiety, depression and quality of life level in the patients when they were discharged from hospital and discharged after 1 month, 3 months. Results Comparing the two groups of patients with anxiety and depression level and quality of life in the hospital, there was no statistically significant difference (t=0.187,0.174, P > 0.05);1 month after discharge, the scores of SAS and SDS respectively (62.97 ± 485), (63.83 ± 5.24) points in the intervention group, the scores of SAS and SDS respectively (64.58 ± 5.15), (65.17 ± 5.11) points in the control group, the difference is statistically significant (t=2.753, 2.321, P<0.05);3 month after discharge, the scores of SAS and SDS respectively(61.04±4.13),(62.25±3.95)points in the intervention group, the scores of SAS and SDS respectively(63.91 ± 4.73),(64.83 ± 4.29)points in the control group, the difference is statistically significant (t=4.621,5.196, P < 0.01); 1month, 3 months after discharge, the total quality of life scores respectively (65.28 ± 12.53), (68.71 ± 12.78) points in the intervention group, the total quality of life scores respectively (62.07 ± 11.27), (63.86 ± 12.13) points in the control group, the difference is statistically significant (t=2.439, 3.803, P < 0.01). The intervention effects and time effects of anxiety, depression and quality of life were statistically significant (W Mauchly's were 0.823, 0.782, 0.757, P <0.05). Conclusions Remote team nursing support can effectively reduce the negative emotions of patients with brain tumor, improve the quality of life, can be used in the department to promote the quality of clinical care.

Analysis of endemic status of schistosomiasis in Gaoyou City from 1970 to 2009 / 中国血吸虫病防治杂志

Objective To explore the changing rule of schistosomiasis endemic situation in Gaoyou City,so as to provide the evidences for schistosomiasis control in lake and marshland regions. Methods The endemic data of schistosomiasis of Gaoy?ou City from 1970 to 2009 were collected to analyze the endemic patterns of schistosomiasis in different control stages compre?hensively. Results In the first years of infection control stage(1970-1975),transmission control stage(1976-1994)and transmission interruption stage(1995-2009),the prevalence rates of schistosomiasis were 4.20%,0.80%and 0 in human and 3.00%,0.51%and 0 in cattle respectively. In 1984,the positive rate of crowd stool tests fell to 0.04%,which was reduced by 99.05%compared with that in 1970. From 1970 to 1980,the positive rates of stool tests of people and livestock were positively correlated significantly(r=0.67,P<0.05). After 1985,no local infection patients or cattle were found. No schistosome infect?ed Oncomelania hupensis snails were found from 1970 to 2009. Conclusion The comprehensive control measures have been insisted in Gaoyou City in different prevention and control stages. Although the snail situation is undulate,the prevalence of schistosomiasis steadily declines and the interruption of transmission has achieved.

Study on the Quality Standard of Flemingia philippinensis / 中国药房

OBJECTIVE:To establish the quality standard of Flemingia philippinensis. METHODS:The properties and micro-scopic characteristics were observed;TLC was adopted for qualitative identification of genistin and genistein;the moisture,total ash and extract were detected;HPLC was adopted for contents determination of genistin and genistein:the column was Thermo BE-TASIL C18 with mobile phase of Acetonitrile-0.5% glacial acetic acid(gradient elution)at a flow rate of 1.0 ml/min,the detection wavelength was 261 nm,column temperature was 25℃,and the injection volume was 10μl. RESULTS:The properties and micro-scopic characteristics of F. philippinensis and F. macrophylla showed strong specificity. TLC spots of genistin and genistein we- re clear and well separated,with no interference in negative control. The moisture was 3.69%-8.37%,total ash was 1.72%-6.74%,and extract was 5.89%-19.65%. The linear range was 0.012 9-2.588 μg for genistin(r=0.999 9)and 0.004 6-0.923 2 μg for genistein (r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 3.0%;recoveries were 99.63%-101.87%(RSD=0.82%,n=6)and 97.19%-100.34%(RSD=1.23%,n=6). CONCLUSIONS:The method is simple,accurate and specif-ic,and can be used for the quality control of F. philippinensis.

Detection of single unit spikes during orthodromic-high frequency stimulation in rat hippocampus.

Deep brain stimulation (DBS) has been used as a treatment of brain diseases such as Parkinson's disease and is a promising therapy for epilepsy. But the mechanisms of high frequency stimulation (HFS) used by DBS are still uncertain. In order to investigate the changes of action penitential firings of individual neurons (single unit activity, SUA) during the period of HFS, a new algorithm based on window detection was designed to detect spikes in broadband-frequency recording signals. The results show that orthodromic-HFS (O-HFS) could excite the neurons in CA1 regions, and the firing rate of interneurons and pyramidal neurons increased significantly. In particular, a decrease in spike amplitude for both interneurons and pyramidal neurons was observed during the period of O-HFS. The amplitude decrease of unit spikes was most remarkable with the presence of HFS-induced population spike (PS). These results suggest that the stimulation pulses of O-HFS could activate the downstream neurons continuously, leading to the downstream neurons being unable to repolarize completely. The results are important for tracking individual neuron activity during HFS and for further understanding of DBS mechanisms.

3D-printed dimethyloxallyl glycine delivery scaffolds to improve angiogenesis and osteogenesis.

Angiogenesis-osteogenesis coupling processes are vital in bone tissue engineering. Normal biomaterials implanted in bone defects have issues in the sufficient formation of blood vessels, especially in the central part. Single delivery of vascular endothelial growth factors (VEGF) to foci in previous studies did not show satisfactory results due to low loading doses, a short protein half-life and low efficiency. Development of a hypoxia-mimicking microenvironment for cells by local prolyl-4-hydroxylase inhibitor release, which can stabilize hypoxia-inducible factor 1α (HIF-1α) expression, is an alternative method. The aim of this study was to design a dimethyloxallyl glycine (DMOG) delivering scaffold composed of mesoporous bioactive glasses and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) polymers (MPHS scaffolds), so as to investigate whether the sustained release of DMOG promotes local angiogenesis and bone healing. The morphology and microstructure of composite scaffolds were characterized. The DMOG release patterns from scaffolds loaded with different DMOG dosages were evaluated, and the effects of DMOG delivery on human bone marrow stromal cell (hBMSC) adhesion, viability, proliferation, osteogenic differentiation and angiogenic-relative gene expressions with scaffolds were also investigated. In vivo studies were carried out to observe vascular formations and new bone ingrowth with DMOG-loaded scaffolds. The results showed that DMOG could be released in a sustained manner over 4 weeks from MPHS scaffolds and obviously enhance the angiogenesis and osteogenesis in the defects. Microfil perfusion showed a significantly increased formation of vessels in the defects with DMOG delivery. Furthermore, micro-CT imaging and fluorescence labeling indicated larger areas of bone formation for DMOG-loaded scaffolds. It is concluded that MPHS-DMOG scaffolds are promising for enhancing bone healing of osseous defects.

HYPERGA STRINEMIA IN HYPERTHYROIDISM / 中华内分泌代谢杂志

Fasting plasma gastrin levels were found to be elevated in 35 cases of hyperthyroidism (265.17?143.17 pg / ml) as-compared with the normal controls (68.30?28.00 pg / ml). The elevated gastrin levels were obviously lowered after the thyroid function was normalized by treatment (115.54?45.86 pg / ml, P
