Analysis of matching degree between drug consumption in Wuhan Huoshenshan Hospital and medicine prepared by medical team / 医学研究生学报

Based on the rapid development of COVID-19 epidemic, China has built Huoshenshan Hospital in Wuhan. This paper analyzes the matching degree between drug consumption in Huoshenshan Hospital and medicine prepared by the medical team in the early stage and the use of medicine in the first week after receiving the patients in Huoshenshan Hospital, and compares it with medicine carried by the medical team. With the novel coronavirus infection developing rapidly, the superior group has a tight schedule and a heavy task, and the preparation time before setting out is only 3 days, the matching degree of pharmaceutical supply can reach 60% within a short period of time, which can already meet the general clinical treatment needs. This paper analyzes the situation of preparing medicine in medical teams in the early stage, and provides experience for future medical teams to carry out the law again.

Curative effect observation of two kinds of root canal preparation for root canal filling on posterior teeth / 重庆医学

Objective To evaluate the influence of ProTaper rotary nickel-titanium files root preparation on root canal filling . Methods 30 cases of molars pulpitis and 20 cases of premolars pulpitis or periapical periodontitis were equally divided into two groups .The group A(30 cases) used the ProTaper rotary nickel-titanium files in root canal preparation and the group B (30 cases) adopted the common K files modified step-back technique for root canal preparation .The influence of the root preparation by 2 sets of apparatus on the effect of root canal filling ,and the several aspects of the root canal filling time ,the matching degree of main root canal file and master gutta-percha ,proper filling rate ,postoperative reaction of root canal filling were compared for conducting the e-valuation .Results In the mean root canal filling time of the group A ,average premolar time was 4 min 25 s and molar was 1 min 30 s ,however in the group B ,average premolar was 5 min 30 s and molar was 11 min 41 s ,the time in the group A was greatly short-ened with statistical difference(P0 .05);the postoperative pain reaction of root canal filling in both groups were very low and weak without statistical difference .Conclusion The ProTaper rotary nickel-titanium files root preparation can accelerate the root canal filling speed ,improve the matching degree of main root canal files and master gutta-percha and simplify the root-filling therapy procedure .
