RESUMO
Objective:To investigate the level of death anxiety and its related factors in patients with newly diagnosed cancer at different stages.Methods:A total of 266 cancer patients in a tertiary oncology hospital were se-lected and investigated at admission(Tl),discharge(T2),and 1 month after discharge(T3).They were assessed with the self-compiled general information questionnaire,Templer's Death Anxiety Scale(T-DAS),Acceptance and Action Questionnaire Second Edition(AAQ-Ⅱ.),and the Chinese version of the Meaning in Life Questionnaire(C-MLQ).The Kruskal-Wallis H test and generalized estimating equation were used to analyze the level of death anxi-ety and its influencing factors in cancer patients at different time points.Results:The Kruskal-Wallis H test showed that the total T-DAS scores and the difference in the scores of the four dimensions were statistically significant at three time points(Ps<0.01),with the highest T1 score and the lowest T3 score.The results of generalized estima-ting equation showed that male gender(β=1.25),junior high school education(β=2.59),worker(β=1.46),farmer(β=1.67),respiratory(β=1.74),digestive system tumor(β=2.51),and AAQ-Ⅱ score(β=0.23)posi-tively predicted death anxiety in patients with cancer.Head and neck(β=-1.73),breast tumors(β=-1.84),stage Ⅰ(β=-2.58)and stage Ⅱ tumors(β=-2.11),and C-MLQ score(β=-0.15)negatively predicted death anxiety in patients with cancer.Conclusion:Death anxiety in patients with newly diagnosed cancer is highest on ad-mission and gradually relieves after discharge.
RESUMO
【Objective】 To explore the current status of positive psychological qualities among college students who had participated in voluntary blood donation in Changsha area, so as to demonstrate that scientific blood donation can promote mental health. 【Methods】 From May to June 2022, 1 440 college students in Changsha was selected as the research subjects by stratified random sampling method. They were divided into groups based on their experience of blood donation. A questionnaire survey was conducted using the General Information Questionnaire, the Chinese College Student Positive Psychological Product Quality Scale, and the Repeated Blood Donation Behavior Survey Scale. 【Results】 There were differences in the six dimensions of positive psychological quality among different family and friends in terms of their support for blood donation, blood donation status among different family members, understanding of voluntary blood donation knowledge (P<0.05). There were differences in positive psychological qualities among different levels of blood reimbursement experiences (cognitive dimension, moderation dimension, transcendence dimension), different blood donation times (moderation dimension, interpersonal dimension), different blood donation volumes (moderation dimension, fairness dimension), different comprehensive blood donation experiences (moderation dimension, transcendence dimension, interpersonal dimension, emotional dimension) and reasons for blood donation (cognitive dimension, moderation dimension, interpresonal dimension, emotional dimension, fairness dimension)(P<0.05). The positive psychological quality of college students was positively correlated with their intention to repeat blood donation behavior (P<0.01), and the difference was statistically significant. 【Conclusion】 The positive psychological quality of college students with blood donation experience in Changsha surpassed those without blood donation experience, and their positive psychological quality was positively correlated to their intention to repeated blood donation. Therefore, it is recommended to encourage voluntary blood donation among college students.
RESUMO
Objective To evaluate the therapeutic effect of Xiao'er Zhixie Paste (XZP) by using the young rat model of chronic diarrhea,and to explore its mechanism.Methods Chronic diarrhea model in young rats was induced by ig senna.Rats were ig with Montmorillonite powder of 1.62 g/kg,XZP of low,medium,and high dose (2.03,4.05,and 8.10 g/kg) for treatment.Loose stools rate,loose stool grade and diarrhea index were determined 1 and 3 d after treatment respectively.The water content of small intestine was measured and blood was collected for testing serum succinate dehydrogenase (SDH),amylase,D-xylose by colorimetric determination,testing serum D-lactic acid,IL-1 β,and TNF-α by Elisa after administration.Results The rate of loose stools in XZP 4.05 and 8.10 g/kg dose group,and diarrhea index in 8.10 g/kg dose group significantly reduced after the first treatment.The loose stools rate of XZP 2.03,4.05,and 8.10 g/kg dose group,diarrhea index,serum D-lactic acid level in 4.05,8.10 g/kg group significantly reduced,and serum D-xylose level in 8.10 g/kg dose group significantly increased 3 d after treatment.However,XZP had no significant effect on SDH,amylase activity and IL-1β,TNF-α levels.Conclusion XZP has obvious therapeutic effect on chronic diarrhea in young rats,the mechanism is to increase improve the absorptive function and permeability of intestinal tract.

RESUMO
Objective: To observe the effects of Guanxinkang injection, a compound traditional Chinese herbal medicine, on ATP-sensitive potassium (K(ATP)) channel subunits in ischemic myocardial cells of rats, and to explore the mechanism of Guanxinkang in protecting myocardial ischemic reperfusion injuries. Methods: Forty-eight Wistar rats were randomly divided into normal group, untreated group, glibenclamide group, pinacidil group, Guanxinkang group and Guanxinkang plus glibenclamide group. The ventricular myocytes were prepared from hearts of normal rats by enzymatic dissociation method. The ischemic ventricular myocytes underwent perfusion with normal Tyrode solution for 10 min, then stopping perfusion 30 min, and followed by 45 min of reperfusion. The glibenclamide, pinacidil and Guanxinkang were added into ventricular myocytes solution directly. Then the solutions were placed at 4 degrees centigrade. After 24-hour freezing at -80 degrees centigrade, mRNA and protein expressions of KATP subunits Kir6.1, Kir6.2, SUR2A and SUR2B were measured by real-time quantitative polymerase chain reaction and Western blotting respectively. Results: In normal rat myocardial cells, there were SUR2A, Kir6.1, and Kir6.2 protein and gene expressions but no expression of SUR2B protein. In the untreated group, all subunit mRNA and protein expressions of KATP increased to some extent as compared with the normal group. Pinacidil, a potassium channel opener, significantly increased mRNA and protein expressions of KATP subunits, while the blocker glibenclamide had a reverse effect. Meanwhile, Guanxinkang injection significantly increased mRNA and protein expressions of K(ATP) subunits but with no significant difference as compared with pinacidil. Conclusion: Guanxinkang injection can obviously enhance the open of KATP channel and thus play a role in cardiovascular protection.
RESUMO
Objective To investigate the effects of atorvastutin on the levels of plasm imflammation markers (hs - CRP, MMP - 3, TNF - α) and intima - media thickness(ITM) of the common carotid artery in patient with hyperlipidemic and atherosclerosis. Methods Fifty patient with hyperlipidemic and atherosclerosis were treated with atorvastatin (10mg qd) for 12 weeks. The levels of TC, TG, LDL -C, HDL -C, hs -CRP, TNF -α and MMP -3 were detected with radioimmmuneassay and eolorimetric methods. Color Doppler echo-cardiography was used to measure intima -media thickness(ITM) of the common carotid artery after 6 weeks and 12 weeks. Results TC, TG, LDL -C, hs -CRP, TNF -α and MMP -3 were decreased significantly(P < 0.01)after 12 weeks. IMT was decreased signifi-cantly(P < 0.05) and HDL - C was increased significantly (P < 0.05) after 12 weeks. Conclusion Atorvastatin could be effective in re-ducing blood - fat and anti - inflammatory action , regulating blood vessel endothelium (BVE) function and reversing structural chan-ges in IMT of the common carotid artery.
RESUMO
Objective This study aimed to discuss the different assessment of pain among medical and nursing staff and cancer patients and supply reference for proper analgesic precept for clinical application and nursing measures. Methods We collected the assessment of psychological pain and physiological pain by 55 hospitalization cancer patients, 40 physicians in-charge and 55 nurses in-charge in one week by Johnson inventory. The assessment results were compared and at the same time the relevant problems of the attitude to cancer pain by patients was also investigated. Results Improper recognition existed in cancer pain treatment by most cancer patients. The physiological pain was higher than the psychological pain assessed by both patients and nurses (P<0.05). But the pain assessment by patients was higher than that by the nurses (P<0.05). The assessment of psychological pain was higher than the physiological pain by doctors and both aspects were lower than those by patients, but no statistical difference was seen (P>0.05). The assessment by doctors was more accurate than that by nurses. Conclusions Routine establishment of pain assessment inventory for patients could instruct patients how to record the degree of their pain. We should strengthen the standard training about pain management knowledge and give timely communication with patients' cancer pain.
