Objective In order to verify an alternative method for the skin corrosion test by using transcutaneous electrical resistance ( TER) test, and to optimize the implementation criteria in OECD TG 430 procedure. Methods According to the OECD TG 430 procedure, Wistar rat skin was used to test the TER values of 16 reference chemicals, and selected the most optimal standard via different implementation criteria. The program B was chosen to make inter-laboratory comparison between 5 laboratories by testing 11 chemicals, which were identified as the optimal standard. Results After the TER test, the result of corrosion test of 16 chemicals were accordant with the reference data ( Kappa value＝0. 64). The program B was the most optimal implementation criteria, and the specificity was 66. 7% and sensitivity was 100%. There were no significant differences between the corrosion estimations of 5 laboratories, and the concordance rate of the 5 laboratories was 72. 7%. Conclusions Transcutaneous electrical resistance (TER) test is an feasible and efficient tool for skin corrosion testing, and may become a good interim test to replace the in vivo test with this ex vivo test in cosmetics chemical safety assessment, thus, to reduce the animal usage in our country.

Objective:To investigate the efficacy of minimally invasive puncture and drainage versus small bone window craniotomy in the treatment of hypertensive basal ganglia hemorrhage. Methods:Seventy-three patients with hypertensive basal ganglia hemorrhage who received treatment in Hequ County People's Hospital from April 2018 to December 2020 were included in this study. They were divided into a minimally invasive puncture and drainage group ( n = 38) and a small bone window craniotomy group ( n = 35) according to surgical methods. Clinical efficacy and postoperative complications were compared between the two groups. Results:At 3 months post-surgery, the National Institutes of Health Stroke Scale score in the minimally invasive puncture and drainage group was significantly lower than that in the small bone window craniotomy group [(3.58 ± 1.23) points vs. (6.87 ± 0.97) points, t = 12.62, P < 0.001]. Barthel index in the minimally invasive puncture and drainage group was significantly higher than that in the small bone window craniotomy group [(62.15 ± 6.78) points vs. (43.15 ± 7.15) points, t = 11.65, P < 0.001]. The total response rate in the minimally invasive puncture and drainage group was significantly higher than that in the small bone window craniotomy group [92.11% (35/38) vs. 74.3% (26/35), χ2 = 4.21, P < 0.05]. The incidence of complications in the minimally invasive puncture and drainage group was significantly lower than that in the small bone window craniotomy group [5.2% (2/38) vs. 25.7% (9/35), χ2 = 6.18, P < 0.05]. Conclusion:Minimally invasive puncture and drainage have better clinical efficacy and fewer postoperative complications in the treatment of hypertensive basal ganglia hemorrhage than small bone window craniotomy. Therefore, minimally invasive puncture and drainage for the treatment of hypertensive basal ganglia hemorrhage are worthy of clinical promotion.

Cognitive dysfunction is one of the serious sequelae of stroke. Brain-computer interface technology, as a rehabilitation technology to promote the neural function recovery, has been gradually applied to the assessment and rehabilitation of cognitive dysfunction after stroke. Brain computer interface establishs connection between the human brain and the machine, conducts closed-loop feedback training, helps patients improve brain functional activities, and finally achieves cognitive rehabilitation. This article introduces the current clinical application of brain-computer interface in rehabilitation of cognitive function after stroke and its possible neurophysiological mechanism, aiming to provide a new idea for rehabilitation of stroke patients.

Objective:To explore the construction and implementation effect of clinical-thinking patterned curriculum for parallel graduate students with "running through clinical diagnosis and treatment process."Methods:In this study, 94 Batch 2016-2017 graduate students with clinical medical professional degree in Shanxi Provincial People's Hospital were selected as the research subjects. Among them, 48 Batch 2017 parallel graduate students were selected as the experimental group. The curriculum of clinical-thinking patterned training of "running through the clinical diagnosis and treatment process" was used. In addition to participating in the degree courses and residency courses, a series of training to improve the clinical-thinking ability were introduced. And 46 Batch 2016 parallel graduate students were divided in the control group, using a traditional curriculum and only participating in degree courses and residency courses. The differences among mini-clinical evaluation exercise (Mini-CEX) scores, direct observation of procedural skills (DOPS) scores, objective structured clinical examination (OSCE) scores and students' satisfaction were compared by t test, chi-square test and repeated measures analysis of variance. Results:The Mini-CEX scores showed the average scores of other aspects except humanistic care were higher than those of the control group, and the score of communication skills was significantly higher than that of the control group [(6.55±0.98) vs. (5.77 ±1.12)], with significant differences ( t=3.62, P<0.001). In the DOPS scores, except for the skills of communication with patients, ability to consider patient's feelings and practice of occupational literacy, the average scores of other aspects of the experimental group were higher than those of the control group, and the real operation-ability score of clinical skills was significantly higher than that of the control group [(6.38 ± 1.38) vs. (5.53±1.23)], with a significant difference ( t=3.12, P=0.002). In terms of the outpatient receiving station, the emergency treatment station, the clinical thinking station①, the clinical thinking station②, the specialist skill station, the auxiliary examination station and the case writing station, their OSCE scores at different stages in the experimental group were higher than those in the control group, and in terms of clinical thinking station①, the score of the experimental group was significantly higher than that of the control group, with a significant difference ( F=6.51, P=0.012). The satisfaction rate of the experimental group in terms of curriculum was higher than that in the control group except for the future career development, and in improving logical-thinking ability, the score of the experimental group was significantly higher than that of the control group, with a significant difference ( χ2=19.18, P<0.001). Conclusion:The curriculum of clinical-thinking ability with "running through the clinical diagnosis and treatment process" can enhance the clinical practical ability of parallel graduate students, making them meet the residential academic standards as soon as possible and effectively promoting the training quality of the students.

Objective To investigate the status quo of fear of disease progression(FoP)in patients after pituitary neuroendocrine tumour surgery and analyse the medication effects of positive coping style on disease perception and FoP.Methods Convenient sampling method was used to select 345 patients with pituitary neuroendocrine tumours who underwent surgical operations in the neurosurgery department of a Grade IIIA hospital in Shanxi Province from January 2022 to January 2023 as the research objects.A general data questionnaire,disease perception questionnaire,medical coping style questionnaire and fear of progression questionnaire-short form(FoP-Q-SF)were used in the investigation.Pearson correlation was employed to analyse the correlations of the disease perception,active coping style and FoP among the patients.Structural equation models were used to analyse the mediating effects of positive coping styles on disease perception and FoP.Results The FoP score of patients after pituitary neuroendocrine tumour surgery was found at(35.02±4.92).FoP was positively correlated with the disease perception(r=0.672,P<0.01),and negatively with the active coping style(r=-0.679,P<0.01).Positive coping styles were positively correlated with disease perception(r=-0.610,P<0.01).Disease perception not only had a direct effect on FoP,but also had an indirect effect on FoP via active coping style,with an intermediate effect value of 0.202(P<0.001),accounting for 25.5%of total effect.Conclusion Postoperative positive coping style in patients with pituitary neuroendocrine tumour is a mediating variable between the disease perception and FoP.Medical staff should dynamically assess and early identify coping styles of patients and adopt personalised guidance programs,therefore to guide the patients to actively cope with the disease,so as to reduce the negative disease perception and alleviate the fear of disease progression of the patients.
