ABSTRACT
@#Objective To explore the anticoagulant strategy of adjusting the dose of warfarin at different stages after mechanical valve replacement of mitral valve. Methods Clinical data of a total of 302 patients, including 76 males and 226 females, with an average age of 50.1±10.1 years, who underwent mechanical mitral valve replacement in the Chinese adult cardiac surgery database from 2013 to 2017 were retrospectively analyzed. According to the dose adjustment strategy of taking warfarin, the patients were divided into a D group (adjusting warfarin dose in days) and a W group (adjusting warfarin dose in weeks) to evaluate the anti-coagulation effect of warfarin. Results The total follow-up time was 423 277 d (1 159.7 years). There was no significant difference in the overall anticoagulant strength, and the warfarin dose adjusted in days was better in the early postoperative period (P<0.05), especially in patients over 60 years. It was better to adjust warfarin dose in weeks in the middle and long periods (P<0.05), especially in patients ≤40 years. In terms of the stability of anticoagulation, it was better to adjust the dosage of warfarin in weeks (P<0.05). It was better to adjust the dosage of warfarin in weeks for early, middle- and long-term anticoagulant therapy after operation (P<0.05), especially in the females aged >40 and ≤50 years. Conclusion Within the target range of international normalized ratio (1.5-2.5), the anticoagulant strategy of adjusting warfarin dose in days after mechanical valve replacement of mitral valve can achieve a better anticoagulant strength, and adjusting the dosage of warfarin in weeks is better in the middle- and long-term after operation. In general, the anticoagulant effect is more stable in the short term when warfarin dose is adjusted on a weekly basis.
ABSTRACT
OBJECTIVES@#To explore the significance of coagulation and immune function indicators in clinical diagnosis and treatment of coronavirus disease 2019 (COVID-19).@*METHODS@#All patients with COVID-19 diagnosed and treated in First People's Hospital of Yueyang from January to March 2020 were enrolled. The general data of patients were collected. The patients were assigned into a light group (=20), an ordinary group (=33), a severe group (=23), and a critically severe group (=7) according to the severity of the disease. Coagulation and immune function indicators of each group were compared, and the relevance of coagulation and immune function indicators was analyzed.@*RESULTS@#The age of COVID-19 patients in Yueyang City was mainly between 45 and 65 years old. There was a significant difference in the coagulation function and immune-related indicators in each group of patients (all <0.05).@*CONCLUSIONS@#There are some abnormalities in coagulation and immune function in patients with COVID-19, which possess significance for clinical diagnosis and treatment of the disease.

OBJECTIVE@#To explore the effect of mmu-circRNA_016901 on the regulation of radiation injury of bone marrow stem cells and its mechanism.@*METHODS@#Bone marrow stem cells were exposed to different dose of X-ray, then the expression level of mmu-circRNA_016901 in bone marrow cells treated with different doses of X-ray was detected. The luciferase reporter gene assay was used to confirm that miRNA1249-5p is the target of mmu-circRNA_016901, and RNA Binding Protein Immunoprecipitation was used to confirm that TGF-β3 is the targeted on miRNA1249-5p，the expression of TGF-β3 and cell proliferation were detected after the expression of mmu-circRNA_01690 was regulated.@*RESULTS@#When the irradiation dose＜6 Gy, there were significant difference in the expression of mmn-circRNA-016901 after the bone marrow mesenchymal stem cells were treated by different doses of irradiation, which showed a statistically significant (P＜0.05). The luciferase reporter gene detection and co-immunoprecipitation experiments confirmed that Mmu-circRNA_016901 could binds to miRNA1249-5p specifically, and overexpression of mmu-circRNA_016901 could regulate miRNA1249-5p negatively, which resulted in a significant increase in TGF-β3 expression and promoting of cell proliferation.@*CONCLUSION@#mmu-circRNA_016901 affects the expression of TGF-β3 through miRNA1249-5p, and thus participates in the regulation of the radiation damage mechanism of bone marrow mesenchymal stem cells.

Objective@#To understand the situation of school medical staff in Guangzhou after adopting multichannel medical model, and to provide reference for school medical team construction.@*Methods@#A total of 1 099 primary and secondary schools in Guangzhou participated in this study through questionnaire survey regarding school medical personnel, basic situation of school medical personnel and work situation.@*Results@#Among the 1 099 primary and secondary schools surveyed, 638(58.05%) of them consisted of 707 full-time school doctors, the eligible rate was 28.20%. The recruitment of school doctors was still based on independent recruitment(55.87%), and 44.13% of the purchase service modes (community deployment, hospital purchase services, and school clinic custody) were deployed. Most of school medical professionals majored in nursing(56.86%), followed by clinical medicine (26.03%) and preventive medicine (9.76%); In terms of professional titles, junior, intermediate and senior certificates accounted for 52.47%, 37.34%, and 1.27%, respectively; More than 68.74% of school doctors worked for less than 5 years; On average, 68.60% of training were provided every six months. About 33.95% of the school doctor were satisfied with salary, 20.79% were not satisfied. Compared with the year 2016, no significant changes were noticed in academic qualifications, professional titles, and working conditions of school medical team, however, increased proportion of staffs with nursing certificate instead of clinical medicine certificate increased, workload and satisfaction towards salary decreased(P<0.01).@*Conclusion@#After adopting the multi-channel deployment model, the construction of school health workforce in Guangzhou has made breakthrough progress. It is proposed to improve the guidelines for the standardization of school doctors, to strengthen the professional skills training of school doctors, and to better improve the overall level of school health work in the city.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the difference in the clinical therapeutic effects on anal fissure at Ⅰ and Ⅱ stages between the acupoint catgut embedding therapy and western medication.</p><p><b>METHODS</b>Sixty patients of anal fissure at Ⅰ and Ⅱ stages were randomized into an embedding therapy group and a western medication group, 30 cases in each one. In the embedding therapy group, the acupoint catgut embedding therapy was applied at bilateral Tianshu (ST 25), Changqiang (GV 1), bilateral Chengshan (BL 57) and Tigangxue (Extra), once a week. In the western medication group, the external inunctum on the wound was given with 0.2% nitroglycerin ointment, once every morning and evening a day. The treatment lasted for 4 weeks continuously in the two groups. The follow-up visit was done for 3 months after treatment. The visual analogue scale (VAS) and anal pain duration were observed and recorded before treatment and on the 3rd day and the 7th day of treatment separately. The clinical therapeutic effects were compared between the two groups.</p><p><b>RESULTS</b>After treatment, on the 3rd day and the 7th day of treatment, VAS score and anal pain duration were all reduced significantly as compared with those before treatment in the patients of the two groups (all<0.01). The differences in the embedding therapy gruop were better than those in the western medication group before and after treatment (<0.01,<0.05). In the 2nd and 4th weeks after treatment, the clinical therapeutic effects in the embedding therapy group were better than those in the western medication group (both<0.05). In 3-month follow-up, the recurrent case in the embedding therapy group was one, and the recurrent case in the western medication group was six.</p><p><b>CONCLUSIONS</b>The acupoint catgut embedding therapy is safe and effective in the treatment of anal fissure at Ⅰ and Ⅱ stages and its recurrent case is lower as compared with the treatment of western medication.</p>
