Objective To explore the methods and clinical application of percutaneous pediculoplasty in the treatment of vertebral pedicular osteolytic metastases.Methods Percutaneous pediculoplasty was performed in 18 patients with (23 Vertebral pedicles ) osteolytic metastases,3 cases localized in thoracic vertebral pedicles and 15 cases in lumbar vertebral pedicles,and two vertebral pedicles involved in 5 cases . Under Multislice helical CT guidance ,2.5~5ml of polymethylmethacrylate ( PMMA ) mixture (ratio of polymer,moner,ultrafluid iodinated oil was 20g:10ml:3ml) was injected into pathologic pedicles in step by step after successful puncture using 11-13G needles. All cases had been followed for 1~18 months.Results All cases were successful punctured. Pain relieved in all cases after percutaneous pediculoplasty.7 cases had cement leakage,among them,cement leaked into tumor tissue in 5 cases(2 cases with leakage into intervertebral foremen),nerve radicular pain occurred in one case,the pain disappeared 3 days later after intravenous mannitol and lower dose dexamethasone drips;the cement leaked into vertebral canal a little without clinical symptom in one case.Conclusion CT-guided percutaneous pediculoplasty is a minimally effective and safe method for osteolytic vertebral pedicular metastases in treatment of pain and enhancement of spinal stability.

OBJECTIVE:To prepare aspirin phospholipid complex (ASP-PC) and conduct the characterization. METHODS:Using the combination rate of ASP and PC as index,single factor test was used to screen the preparation method of ASP-PC,PC type,solvent type,reaction time,reaction temperature,solvent volume and drug-lipid ratio. The verification test was conducted. UV spectrophotometry,Thermogravimetric analysis,X-ray diffraction and Fourier transform infrared spectroscopy were used for the characterization of ASP-PC. RESULTS:Magnetic stirring-condensing reflux method was adopted,drug-soybean phospholipids ratio was 1:3 (mol/mol),solvent was tetrahydrofuran,reacting for 3 h under 58 ℃. The average combination rate of prepared ASP-PC was 83.52%(RSD=1.16%,n=3). Compared with ASP,physical mixture of ASP and PC,UV spectrum showed that ASP-PC had no new absorption peak. Thermogravimetric analysis,X-ray diffraction and Fourier transform infrared spectroscopy showed the ASP and PC in ASP-PC were interacted;and ASP-PC changed little in quality within 0-300 ℃. CONCLUSIONS:ASP-PC can be successfully prepared,in which,ASP and PC were combined successfully;while there are still trace amounts of ASP in the form of crystals.

Purpose:
Elder self-neglect is a global public health issue and should be taken seriously at large. Nurses,usually working directly with elderly patients, have a better understanding of what factors may causeelder self-neglect. In this qualitative study, we explored the influencing factors of elder self-neglect fromthe perception of nurses in the context of Chinese culture.
Methods:
Face-to-face, in-depth interviews were conducted from November 2018 to December 2018.Purposive sampling was used. Twenty one participants recruited from eight geriatric wards of a generalhospital located in Wuhan were interviewed. A content analysis of qualitative nature was performed toanalyze the data.
Results:
Our conceptual model illustrated the findings based on the three themes of the conflict betweenpersonal recognition and social judgment, the choice between current needs and individual beliefs, aswell as the compromise between insufficient abilities and limited resources.
Conclusion
Nurses together with family members and social workers can help older adults improvetheir awareness of self-neglect to bridge the gap with social judgment, learn to focus on their own needs,as well as seek as much support as possible. Nurses should also respect the autonomy and selfdeterminationof elder self-neglecters because self-neglect is related to older adults' values. Furthermore,larger studies are needed to quantitatively test and refine the model.

Objective:We compare the consistency, similarities and differences of operating procedures, data and conclusions of air-charged catheters(ACC) and water-filled catheters(WFC), as simultaneously using ACC and WFC in pressure-flow study(PFS).Methods:This study was a prospective, synchronously controlled study, including eligible patients who underwent PFS in the Department of Urology, Beijing Chaoyang Hospital from January 2021 to March 2021. Inclusion criteria: ① Patients need PFS for lower urinary tract symptoms like frequency of urination, urgent urination, urinary incontinence and dysuria; ② Age over 18 years old. Exclusion criteria: ① Unable to complete or cooperate during the urodynamic test; ② Patients with severe urethral stricture or acute stage urinary tract infection; ③ Pregnant women. The bladder pressure was measured continuously by using a 7FDR T-DOC ?AC three-chamber bladder pressure tube, which linked to ACC sensor and improved WFC pressure conduction module. At the same time, 7FA T-DOC ?AC single-lumen rectal pressure tube and 7F Labori-CAT411 double-lumen water sac abdominal pressure tube was used to measure the ACC and WFC rectum pressure, respectively. We recorded the Pdet, Pves and Pabd measured by ACC and WFC, at the point of initial sitting position, bladder filling at 100 ml, 150 ml, 200 ml, cough, Q max, maximum Pdet and the end of urination, and compared the mean values, differences, and consistencies of our data. Result:A total of 63 patients (26 female, 37 male) were included in this study, with an average age of 59.19 years (25-86 years old). During bladder filling phase, the mean values of Pves measured by ACC and WFC were 30.78/24.67cmH 2O (initial sitting position), 29.79/25.13cmH 2O (100 ml), 30.87/25.90cmH 2O (150 ml) and 30.95/26.17cmH 2O(200 ml), respectively, the mean value of Pabd were 30.03/24.17cmH 2O (initial sitting position), 28.81/21.78cmH 2O (100ml), 28.89/21.38cmH 2O (150ml), 28.44/21.60cmH 2O (200ml), respectively, and were significantly different at each sampling point ( P<0.01). During urination period, no significant differences were found in data( P>0.05), and the data measured with ACC and WFC system have good consistency. There were significant differences in Pves(mean 57.30/49.95 cmH 2O, respectively) and Pdet(mean 54.21/43.10 cmH 2O, respectively) between ACC and WFC in cough ( P<0.01), but there was a strong linear correlation between these data between two systems(R 2=0.792 in Pves and 0.756 in Pabd). Bland-Altman analysis showed that detrusor pressure at the maximum urine flow rate maintained good consistency between ACC and WFC, which 95% CI was -13.9 cmH 2O to 15.8 cmH 2O. Conclusions:In PFS, although the ACC measurement values (Pves and Pabd) during the filling phase are higher than those WFC readings, but the absolute measurement difference is small, so there is no practical meaning in clinical practice. There was no significant difference in detrusor pressure measured during voiding phase, which indicated that the urodynamic judgment and clinical conclusions of the two systems are highly consistent in judgment of the detrusor contractility and the bladder outlet obstruction.

BACKGROUND/OBJECTIVES:
Tibetan tea is a kind of dark tea, due to the inherent complexity of natural products, the chemical composition and beneficial effects of Tibetan tea are not fully understood. The objective of this study was to unravel the composition of Tibetan tea using knowledge-guided multilayer network (KGMN) techniques and explore its potential antioxidant and hypolipidemic mechanisms in mice.MATERIALS/METHODS: The C57BL/6J mice were continuously gavaged with Tibetan tea extract (T group), green tea extract (G group) and ddH 2 O (H group) for 15 days. The activity of total antioxidant capacity (T-AOC) and superoxide dismutase (SOD) in mice was detected.Transcriptome sequencing technology was used to investigate the molecular mechanisms underlying the antioxidant and lipid-lowering effects of Tibetan tea in mice. Furthermore, the expression levels of liver antioxidant and lipid metabolism related genes in various groups were detected by the real-time quantitative polymerase chain reaction (qPCR) method.
RESULTS:
The results showed that a total of 42 flavonoids are provisionally annotated in Tibetan tea using KGMN strategies. Tibetan tea significantly reduced body weight gain and increased T-AOC and SOD activities in mice compared with the H group. Based on the results of transcriptome and qPCR, it was confirmed that Tibetan tea could play a key role in antioxidant and lipid lowering by regulating oxidative stress and lipid metabolism related pathways such as insulin resistance, P53 signaling pathway, insulin signaling pathway, fatty acid elongation and fatty acid metabolism.
CONCLUSIONS
This study was the first to use computational tools to deeply explore the composition of Tibetan tea and revealed its potential antioxidant and hypolipidemic mechanisms, and it provides new insights into the composition and bioactivity of Tibetan tea.
