Objective To investigate the origin of prostatic blood-supply by digital subtraction angiography (DSA) and provide references for the arterial embolization of prostatic hyperplasia. Methods A total of 72 male patients with successful selective and super-selective prostatic arterial catheterization angiographies were observed and recorded the original arterial blood-supply of the prostate, number of the prostatic arteries and the predominant blood supply. Results The blood-supply of prostate is very complicated including the original prostatic arterial supply from the inferior vesicle arteries (69); the internal iliac arteries (63); the internal pudendal arteries (52); the inferior rectum arteries (29); the superior vesicle arteries (14). The predominant arterial supply include the internal iliac arteries (37); the inferior vesicle arteries (20); the internal pudendal arteries (6) and the inferior rectum arteries (2). Conclusion Arterial contrast medium angiography can correctly demonstrate and assess the original arterial supply of prostate, providing significant guidance for further interventional embolization.

OBJECTIVE To report the investigation on validating clinical moist sterilizer by applying wireless thermo-loggers in accordance with the advanced Euro and British standards.METHODS The validation had been implemented with microbiological tests and thermometric tests to measure the temperature distribution of the chamber of sterilizer,the temperature and time relation inside the tested package of small and challenge loads,the pressure of the chamber and the temperature beside the drainage.RESULTS The measurements presented the relation between temperature and time measurements of the spots inside the chamber of the tested sterilization loads.CONCLUSIONS The measurement results indicate directly the operation condition and the temperature-time relation inside sterilization loads.These measurements are helpful for controlling sterilization quality.The results of microbiological tests are negative,which are consistent with that of thermomeric tests.

Objective To detect the independently designed synthetic peptide adsorbed to the titanium surface and its inhibitory effect on streptococcus gordonii, and to provide a new means for antibiosis reseach on oral implants. Methods The physical and chemical properties of the synthetic peptide and antimicrobial peptide were measured by ExPASy Prot?Param tool, ProtScale analysis, circular dichroism and Zeta potential instrument. The synthetic peptide was anchored on the surface of the titanium specimen through incubation at room temperature. The adsorption of the synthetic peptide to the titani?um surface was examined by X-ray photoelectron spectroscopy (XPS) and the atomic force microscope (AFM). The inhibitory effect on streptococcus gordonii of the synthetic peptide fixed on the titanium surface was viewed by confocal laser scanning microscopy (CLSM). The destructive effects of the synthetic peptide and the antimicrobial peptide on streptococcus gordonii were observed through the transmission electron microscope (TEM). Results The independently designed synthetic peptide still had the physical and chemical properties that the antimicrobial peptide desired. The synthetic peptide had already been detected on the titanium surface after incubated in a 5 g/L synthetic peptide solution. The titanium specimen fixed with the synthetic peptide inhibited the survival and adhesion of streptococcus gordonii. Conclusion It suggests that the indepen?dently designed synthetic peptide might have reached the goal of bacterial inhibition on the titanium surface.

Abstract: Objective　To analyze the impact of the flood disaster on the distribution of Oncomelania snails in 2020 in Wuhu City, to provide scientific basis for formulating the "14th Five-Year Plan" for schistosomiasis control and precise prevention and control measures in Wuhu City. Methods　Systematic sampling combined with environmental spot check was used to investigate the distribution of snails in the historical snail's environment, existing snail's environment and suspected snail's environment in Wuhu City. The collected snails were crushed and examined by microscope to understand the death and life of snails and the infection of Schistosoma japonicum, and the density of live snails and other indicators were counted. Results　The historical area of snails was 14 475.24 hm2 in Wuhu City, and the existing area of snails was 4 588.72 hm2, including 4 210.32 hm2 for lake type and 378.40 hm2 for hill type snails. The average occurrence rate of live snails was 14.59%, and the average density of live snails was 0.50 snails/0.1 m2 in Wuhu City. There were 2 745 snail breeding environments, of which 491 were lake type and 2 254 are hill type, accounting for 17.89% and 82.11% respectively. The existing snail area was mainly distributed in the beaches and ditches, accounting for 92.51% and 6.29% of the existing snail area respectively. Some snails were distributed in ponds, paddy fields and other environments. Among all the historical snail habitats, the majority were class Ⅱ and class Ⅲ environments (which still have the basic conditions for snail breeding at present), with a total of 1 739 sites (blocks), accounting for 63.35% of the total environment. No schistosomiasis infected snails have been found, and the newly discovered and recovered snails cover an area of 268.21 hm2 in Wuhu City. Conclusions　The distribution of snails is extensive in Wuhu City, and snails are mostly distributed in beaches, which are vulnerable to the impact of flood disasters. The spread of Oncomelania snails is found in 30 marshlands in 3 counties in this survey. It is necessary to continue to strengthen snail monitoring after disasters, and take class Ⅱ and class Ⅲ environments as key areas for snail monitoring, so as to find, identify and evaluate the risk of schistosomiasis transmission as soon as possible, to avoid or reduce the impact of flood disasters on the process of schistosomiasis control, and promote the process of schistosomiasis elimination.

Objective To observe the effect of power-assisted functional electrical stimulation (PAFES)therapy on ankle joint function recovery in stroke patients.Methods Ninety hemiplegic stroke patients were randomly and evenly divided into a control group,a PAFES group,and a neuromuscular electrical stimulation (NMES)group.All groups received conventional rehabilitation training.PAFES group adopted PAFES treatment on affected lower extremities and NMES group was given the NMES therapy on the tibialis anterior of the affected lower limbs,in addition to conventional rehabilitation training.The active range of motion (AROM) of ankle dorsiflexion,FuglMeyer motor assessment (FMA),Barthel index (BI) and Ankle flexion and extension movement (AFEM) in 10 seconds were evaluated before the trial and after 4 weeks treatment.Results After treatment,there were significant differences in the AROM of ankle dorsiflexion,FMA,BI and AFEM (P ＜ 0.05) compared with before treatment within each group.The improvement of AROM of ankle dorsiflexion in PAFES group (8.19 ± 3.39) ° and the values in NMES group (8.96 ± 3.68) ° were to a significantly greater extend than control group (3.88 ± 4.10) ° (P ＜0.05) ; the improvement of FMA and BI in PAFES group was also superior to those in NMES group and control group (P ＜ 0.05).Conclusion The intelligent PAFES therapy could help improve AROM of ankle dorsiflexion,the motor function of the affected lower extremity and the ability of the activities of daily living in stroke patients.
