Objective To explore the effect of using new Chinese medicine cases on sharp protection in stomatological department. Methods After immersing the packaging paper in traditional Chinese medicine, it was made into a new type of protection case. Totals of 200 patients were randomly divided into the observation group (100 cases) and control group (100 cases). They were given the protection of new Chinese medicine case or traditional protection method, respectively. The incidence of prolapse, rate of satisfaction in doctors and the stress of nurses were compared between the two groups. Results The incidence of sharp prolapse in the observation group during installing and before using were both two cases, and the control group were 26 and 28 cases, there were significant differences between the two groups (χ2 =32. 54,21. 32,respectively;P<0. 01). In the observation group, fifteen doctors were fully satisfied, eighteen doctors were satisfied and 7 doctors were generally satisfied, which were significantly higher than those in the control group (Z=26. 538 5,P<0. 01). In the observation group, thirty nurses were normal, seven nurses had mild pressure, one nurse had moderate pressure, and one nurse had severe pressure, which were significantly higher than those in the control group (Z=7. 233 8,P<0. 05). Conclusions Traditional Chinese medicine protection case can effectively reduce incidence of sharp prolapse, improve doctors′ satisfaction with nursing work, relieve nurses′ psychological pressure, which can better improve the ability of social service.

Objective To evaluate the molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones against of Oncomelania hupensis snails in snail habitats in marshland areas. Methods From September to October, 2022, marshlands were sampled from Dantu District, Zhenjiang City, Jiangsu Province as study areas, and assigned into four groups, of approximately 3 000 m² per group. In Group A, environmental cleaning was performed, followed by spraying 5% niclosamide ethanolamine salt granules with knapsack sprayers at a dose of 40 g/m², and in Group B, 5% niclosamide ethanolamine salt granules were sprayed with knapsack sprayers at a dose of 40 g/m² without environmental cleaning, while in Group C, environmental cleaning was conducted, followed by spraying 5% niclosamide ethanolamine salt granules with drones at a dose of 40 g/m², and in Group D, 5% niclosamide ethanolamine salt granules were sprayed with drones at a dose of 40 g/m² without environmental cleaning. Then, the study areas in each group were equally divided into six blocks, with Block 1 for baseline surveys and blocks 2 to 6 for snail surveys 1, 3, 5, 7, 14 days following chemical treatment. The mortality of snails and the reduction of the density of living snails were calculated. Results A total of 132 frames were surveyed during the period from September to October 2022, and the occurrence of frames with living snails and means density of living snails were 61.36% (81/132) and 1.58 snails/0.1 m², respectively. The overall mortality rates of snails were 43.02% (77/179), 38.69% (77/199), 47.78% (86/180) and 31.02% (58/187) 14 days following chemical treatment in groups A, B, C and D, respectively (χ² = 11.646, P < 0.05), and there were differences detected in the snail mortality between group A and D, and between groups C and D (both P_adjusted values < 0.05). The adjusted mortality rates of snails were 37.42%, 36.07%, 38.85% and 40.40% in groups A, B, C and D 14 days post-treatment, and the density of living snails decreased by 48.10%, 63.29%, 67.09% and 69.62% 14 days post-treatment relative to pre-treatment, respectively. Conclusions Chemical treatment with drones is feasible for O. hupensis snail control in marshland areas; however, the molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones is comparable to spraying chemicals manually in marshland areas regardless of environmental cleaning.
