ABSTRACT
@#With the rapid development of the nuclear industry, the uranium-exposed population is rapidly expanding. Kidney injury is a major health concern for uranium-exposed population because uranium is initially retained in the kidneys and induces chemical toxicity. However, the commonly used clinical markers of kidney injury usually show significant changes in the late stages of such damage, making it difficult to monitor the occupational health of uranium-exposed population. In recent years, a number of biomarkers that can reflect early kidney injury caused by uranium have been identified and investigated by enzyme-linked immunosorbent assay and protein blotting. This article will review the studies in this area, with the aim of providing a basis for the diagnosis and understanding the development and prognosis of uranium-induced kidney injury.
ABSTRACT
Objective:To investigate the relationship and intrinsic mechanism between disease uncertainty, coping style, social support and caregiver burden of primary caregivers of stroke, in order to provide a theoretical basis for reducing the burden of care and improving the quality of care for stroke caregivers.Methods:In this study, the main caregivers of 314 stroke patients hospitalized in Xinjiang Uygur Autonomous Region People's Hospital from December 2021 to May 2022 were selected by convenience sampling method, and cross-sectional surveys were conducted using the general data questionnaire, the Family Scale of Disease Uncertainty, the Simple Coping Style Questionnaire, the Social Support Rating Scale, and the Caregiver Burden Scale. Model 4 in Hayes′ SPSS-Process program was used to test the mediation effect, and Model 15 was used to test the mediation effect of social support.Results:The positive predictive effect of disease uncertainty in the primary caregiver of stroke patients on the burden of caregivers was significant ( β=0.665, P<0.01). Active coping played a partial mediating role between disease uncertainty and caregiver burden, with a mediating effect of 0.306 and a mediating effect of 31.8%. The interaction between disease uncertainty and social support had a significant predictive effect on caregiver burden ( β=-0.033, P<0.05), and the interaction item between active response and social support had a significant predictive effect on caregiver burden ( β=-0.019, P<0.05). Conclusions:Positive coping is an important psychological mechanism between disease uncertainty and caregiver burden, and social support can alleviate the influence of disease uncertainty on caregiver′s burden, and can also strengthen the weakening effect of positive coping on caregiver′s burden.
ABSTRACT
The processing of traditional Chinese medicine(TCM) is a traditional pharmaceutical technology,which meets the development demand of the treatment based on syndrome differentiation of TCM. It is one of the important means to guarantee the quality of Chinese medicine and improve the clinical efficacy of TCM. Medical institutions of traditional Chinese medicine should take the advantages and characteristics of traditional Chinese medicine as the foundation, vigorously carry out processing technology for traditional Chinese medicine, rich clinical drug varieties of traditional Chinese medicine, and develop such characteristics of TCM as treatment based on syndrome differentiation and individualized drug treatment. The processing of temporary prescriptions is one of the important means to reflect the characteristics of TCM, and it is of great significance to improve the curative effect of TCM. Based on working practice, this paper summarized the development current status, significance, technical standards and samples of processing variety and methods etc in order to provide thoughts for the processing technology of temporary prescriptions in medical institutions.
ABSTRACT
Objective To investigate the hemostasis effect of alginate dressing for puncture point bleeding after peripherally inserted central catheter (PICC) by ultrasound-guided modified Seldinger technique (MST).Methods Between November 2013 and May 2016, 538 cases of cancer in our department underwent PICC, including 270 cases from November 2013 to February 2015 selected as control group (after PICC was successfully placed, sterile gauze and 3M transparent film were used to fix the puncture point) and 268 cases from March 2015 to May 2016 selected as observation group (after PICC was successfully placed, alginate dressing, sterile gauze and 3M transparent film were used to fix the puncture point).The patients in both groups were given 20 minutes of pressure for puncture point and elastic bandage compression fixation for 24 h.The degree of puncture point bleeding and times of dressing change in 24 h and 24-72 h between the two groups were compared.Results In the observation group, mild, moderate, and severe bleeding was seen in 232 cases, 34 cases, and 2 cases within 24 h, and in 242 cases, 25 cases, and 1 case between 24-72 h, respectively.In the control group, mild, moderate, and severe bleeding was seen in 12 cases, 196 cases, and 62 cases within 24 h, and in 21 cases, 212 cases, and 37 cases between 24-72 h, respectively, with significant differences (Z=-18.647, P=0.000;Z=-18.768, P=0.000).In the observation group, there were zero, once, twice, and ≥3 times of puncture point dressing change in 232 cases, 33 cases, 3 cases, and 0 case within 24 h and in 242 cases, 25 cases, 1 case, and 0 case between 24-72 h, respectively.In the control group, there were zero, once, twice, and ≥3 times of puncture point dressing change in 12 cases, 196 cases, 51 cases, and 11 cases within 24 h and in 21 cases, 209 cases, 37 cases, and 3 cases between 24-72 h, respectively, with significant differences (Z=-18.560, P=0.000;Z=-18.755, P=0.000).Conclusion The hemostasis effect of alginate dressing for puncture point bleeding after ultrasound-guided PICC by MST is satisfactory.
ABSTRACT
Objective:To find out the transformation reasons of the processing methods for Matrii sultas Exsiccatus through the bencaological study and the modern experimental researches.Methods:The different processing methods for Matrii sultas Exsiccatus in different periods were collected through the researches on the ancient agrostology and the modern processing standards.Furthermore,different processed products were prepared and analyzed by Raman spectroscopy.Results:There were significant differences in the processing methods for Matrii sultas Exsiccatus in the ancient herbal documents while tending to be the same in the modern processing standards.No difference was shown in the Raman spectrogram between Matrii sultas Exsiccatus and Weathered mirabilite produced by the processing methods in the ancient agrostology.The Raman characteristic peaks of the two processed products were as follows:1 153,1 132,1 102,992,648,632,621,466,450 cm-1,which were in line with the Raman spectrogram of the products produced by the modern processing methods.Conclusion:The change of processing methods for Matrii sultas Exsiccatus has certain reasons,which is worthy of further studies.
ABSTRACT
Objective:To determine the release and in vitro transdermal rate of tetrahydropalmatine in Xiaoji Aitong cataplasmas in rats. Methods:Using the self-made drug release determination devices and the modified Franz diffusion cells, and the skin of rats as the barrier, the release and in vitro transdermal rate of tetrahydropalmatine in Xiaoji Aitong cataplasmas were detected by HPLC. Re-sults:Tetraydropalmatine within the range of 0. 51-10. 22 μg showed a good linearity (r=0. 999 7), and the average recovery was 98. 49%(RSD=0. 84%,n =9). The release of tetrahydropalmatine in 80 min was 63. 60%, and the skin permeation rate was 23. 15% in 24h. Conclusion:Xiaoji Aitong cataplasmas have good drug release and transdermal performance.
ABSTRACT
<p><b>OBJECTIVE</b>The skeletal Class III malocclusion often occurs in ethnic Asia population, and it is difficult to obtain an ideal results if only treated with protraction headgear (PH). However, the combined rapid palatal expansion (RPE), Edgewise Technique and PH can reach it, so the authors investigated the methods and characteristics of combined RPE, Edgewise Technique and PH in the treatment of skeletal Class III malocclusion.</p><p><b>METHODS</b>Fifteen patients, aged 8.5-12 years, including six males and 9 females, with skeletal Class III malocclusion and maxillary retrusion were selected for this study. Radiographs of left hand and wrist showed that all patients were at the pre-pubertal stage. The duration of treatment was nine months on average.</p><p><b>RESULTS</b>The SNA and A-ptm increased with a mean of cephalometric analysis, which showed significant difference (P < 0.05).</p><p><b>CONCLUSION</b>Obvious skeletal and profile changes can be achieved with combined RPE, Edgewise Technique and PH in the treatment of early skeletal Class III malocclusion.</p>
