Methods: 82 patients with functional constipation who entered a hospital in Qingyang City from October 2020 to February 2021 were selected by convenient sampling for nursing intervention. The experimental group was given Chinese medicine food therapy combined with Baduanjin, and the control group was given general nursing. The intervention lasted 14 days. The scores of symptom checklist 90 (SCL-90) and quality of life analysis of constipation patients were recorded. Results: compared with the control group, the experimental group can significantly reduce the scores of symptom checklist 90 and quality of life analysis of constipation patients, indicating that the experimental group is better than the control group in improving the symptoms of constipation patients (P < 0.05). Conclusion: the experimental group can significantly reduce the scores of SCL-90 and QOL analysis of constipation patients, and the intervention results are better than the control group.展开更多

However, the effects of drugs on the expression of Nogo-A in cervical spinal cord are still unclear. OBJECTIVE： To observe the effect of Fujian tablet on the expression of Nogo-A mRNA in cervical spinal cords of middle cerebral artery occlusion （MCAO） rats, and to investigate the possible regulatory effect of Fujian tablet on the regenerated microenvironment of spinal conduction bundle. DESIGN： A randomized and controlled trial taking Wistar rats as experimental animals. SETTING： Department of Neurology, Affiliated Hospital of Shandong University of Traditional Chinese Medicine. MATERIALS： This experiment was carried out in the laboratory of Shandong Academy of Medical Science between June 2005 and July 2006. A total of 40 healthy male Wistar rats, aged 12 weeks, weighing 250 - 300 g, were provided by the Experimental Animal Center of Shandong University. Fujian tablets （main components： Heshouwu, Yinyanghuo, etc） were provided by office of Pharmaceutics of Shandong University of traditional Chinese medicine. Nogo-A detection kit was provided by Wuhan Boster Biotechnology Co.,Ltd., and batch number was 040309009. This experiment was approved by Local Animal Ethics Committee. METHODS： Forty male rats were randomly divided into 4 groups, with 10 in each： normal group, sham-operation group, model group and administration group. Rats in the administration group and model group were subjected to MCAO. Rats in the sham-operation group underwent the same craniotomy, and their middle cerebral arteries （MCA） were not occluded. Rats in the normal group were untouched. Rats in administration group were intragastrically administrated with the solution of Fujian tablet at a dose of 9 g/kg and others were given equal dosage of normal saline two days later. The treatments were done once a day and the course totaled 2 weeks. MAIN OUTCOME MEASURES： The expression of Nogo-A mRNA in slices of cervical spinal cords. RESULTS： Forty rats were involved in the final analysis. The expression of Nogo-A mRNA in the cervical spinal cord of rats in the administration group and model group was significantly decreased as compared with that in the normal group （P 〈 0.01 and P 〈 0.05, respectively）. The expression of Nogo-A mRNA in the administration group was also significantly weaker than that in the model group （P 〈 0.05 ） . CONCLUSION： Fujian tablet can inhibit the expression of Nogo-A mRNA in cervical spinal cords of MCAO rats, which facilitates regeneration and remodeling of cervical spinal cords.展开更多

In order to reduce this series of risks, Ji'nan Blood Supply and Insurance Center conducted laboratory tests for anti-HIV primary screening for unpaid blood donors from January 2015 to September 2021.Methods: a total of 259 blood samples were collected and sent to the laboratory of Ji'nan Center for Disease Control and Prevention for confirmation for 100% anti-HIV testing. In addition, the distribution of their blood donation times, age, gender, occupation, education, transmission route and native origin were summarized and analyzed. Results: 40 positive, 26 to 40 (47.5%), male blood donors (97.5%), college degree or above (55%), same-sex group (77.5%) were the majority;Most infections were initial blood donation (92.5%);HIV infection was relatively high in all occupations (10%).Conclusion: the blood safety and quality is especially important to establish a fixed and volunteer team of low-risk unpaid blood donors. Medical staff should strengthen the HIV screening of blood donors, improve the blood safety and quality, in order to do a good job of AIDS, high-risk behavior, confidential blood abandonment, and safe blood donation related knowledge publicity, do a good job of communication with blood donors and the evaluation of blood donors.展开更多
