Objective:To investigate the effect of saikosaponin A on depressive-like behaviors and hippocampal cyclic adenosine monophosphate response element-binding(CREB) protein expression in olfactory bulbectomized mice.Methods:Totally thirty male SPF-grade C57BL/6J mice, six weeks old, were randomly divided into 3 groups ( n=10 in each group): the control group, the olfactory bulbectomy group, and the saikosaponin A group.Olfactory bulbectomy was performed to damage the olfactory bulbs in the mice of bulbectomy group and saikosaponin A group, while the mice of control group only had a cranial drill hole at the same coordinates without damaging the olfactory bulbs. Mice in saikosaponin A group were administered saikosaponin A solution (dose: 5 mg/kg) via gavage, while mice in the control and olfactory bulbectomy groups were given the same volume of 0.9% NaCl solution once a day for 21 days. The depressive-related behavioral changes of mice in each group were evaluated by open field test, tail suspension test, forced swimming test, and weight measurement. The expression of CREB in the hippocampus of mice were detected by Western blot. Graphpad prism 5 software was used for data analysis.The data comparison among the multiple groups was conducted by one-way ANOVA and further pairwise comparisons were conducted by Tukey test. Results:(1) The results of weight measurement showed that there was no significant difference in body weight among the three groups( F=0.468, P=0.631) on the day of the olfactory bulbectomy surgery, but there was a statistically significant difference in body weight among the three groups ( F=37.340, P<0.001) on the 28th day after the olfactory bulbectomy.The body weight of mice in the olfactory bulbectomy group was lower than that of the control group ((24.09±1.01) g, (27.22±0.58)g)( P<0.05). The body weight of mice in the saikosaponin A group((26.23±0.83)g) was higher than that of the olfactory bulbectomy group( P<0.05). There was a statistically significant difference in body weight differences among the three groups of mice ( F=48.180, P<0.001). The body weight difference of mice in the olfactory bulbectomy group was lower than that of the control group ((2.34±0.96) g, (5.57±0.72) g) ( P<0.05). The body weight difference of mice in the saikosaponin A group was higher than that of the olfactory bulbectomy group ((4.74±0.56) g, (2.34±0.96) g) ( P<0.05).(2) The results of the open field test showed that there were statistically significant differences in the central area residence time and total activity distance in mice among the three groups ( F=27.03, 10.98, both P<0.001). The central area residence time ((13.87±4.59) s) and total activity distance ((35.67±4.88) m) of mice in the olfactory bulbectomy group were both less than those of the control group ((27.44±2.76) s, (59.02±16.21) m) (both P<0.05).The central area residence time ((21.77±4.78) s) and total activity distance ((52.33±10.41) m) of mice in the saikosaponin A group were both higher than those of the olfactory bulbectomy group(both P<0.05).(3) The results of tail suspension test showed that there was a statistically significant difference in immobility time among the three groups ( F=74.57, P<0.001). The immobility time of mice in the olfactory bulbectomy group was longer than that of the control group ((148.20±8.84)s, (97.89±8.64)s) ( P<0.05). The immobility time of mice in the saikosaponin A group((135.70±11.09)s) was less than that of the olfactory bulbectomy group( P<0.05). (4) The results of forced swimming test showed that there was a significant difference in immobility time among the three groups ( F=51.73, P<0.001). The immobility time of mice in the olfactory bulbectomy group was longer than that of the control group ((61.39±5.20) s, (40.80±4.30) s) ( P<0.05).The immobility time of mice in the saikosaponin A group((53.52±4.13)s) was less than that of the olfactory bulbectomy group( P<0.05). (5) The results of Western blot showed that there was a significant difference in hippocampal CREB protein expression among the three groups ( F=13.32, P<0.001).Compared with the control group, hippocampal CREB protein expression of mice in the olfactory bulbectomy group was significantly down-regulated(0.51±0.15, 1.45±0.61) ( P<0.05).Compared with the olfactory bulbectomy group, hippocampal CREB protein expression in the saikosaponin A group(0.97±0.09) was up-regulated( P<0.05). Conclusion:Saikosaponin A can significantly alleviate the depressive-like behaviors in olfactory bulbectomized mice, and its mechanism may be related to the up-regulation of CREB protein expression in the hippocampus.

Objective:To explore the occupational adaptability of psychiatric medical caregivers from the perspective of a composite ecosystem.Methods:Using purposive sampling combining with snowball sampling and based on ecosystem theory, an interview outline was set up to conduct semi-structured interviews with psychiatric medical caregivers from October to December 2023. The Colaizzi 7-step analysis method was used to extract the themes.Results:Totally 15 psychiatric medical caregivers aged 44-61 years, 4 males and 11 females. There were three themes in the study: microsystems-changes in cognition, emotion, and physical and mental health; mid-level system-support and difficulties for families, hospitals, and nursing staff institutions; the macro system-social psychological support system was lacking.Conclusions:Psychiatric medical caregivers lack professional knowledge, have more negative emotions in their emotional experiences, and have a serious lack of mental health support systems. There are biases and misunderstandings towards them in society. It is recommended that managers pay attention to the physical and mental health of psychiatric caregivers and improve their work adaptability.

Objective:To explore the effects of nurse as standardized patient (NSP) in clinical apprenticeship and objective structured clinical examination (OSCE) of psychiatric nursing.Methods:Totally 260 undergraduate nursing students admitted to the School of Nursing of a medical university in 2017 were selected into experimental group, who were taught in combination of real patients and NSP, and received assessment of clinical apprenticeship skills through OSCE involving NSP. Totally 286 undergraduate nursing students admitted in 2016 were selected into control group, who received conventional clinical apprenticeship teaching and assessment. The discrimination and difficulty of the assessment of the experimental group was considered, and the test scores, the degree of recognition of the assessment form by the nursing students, and the ability of critical thinking were compared between the two groups.Results:Totally 247 nursing students in the experimental group and 280 in the control group completed the study. The degree of difficulty and discrimination met the assessment requirements. There was a statistically significant difference in apprenticeship performance between the two groups ( P<0.01) . After OSCE, the recognition scores of the two groups for OSCE were (3.22±0.64) and (4.17±0.58) , respectively, and the difference was statistically significant ( P<0.01) . The total scores of Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV) of the two groups were (278.29±25.66) and (289.53±35.43) , respectively, and the difference was statistically significant ( P<0.01) . There were statistically significant differences in the scores of CTDI-CV in 4 dimensions between the two groups, they are open-mindedness, analytical ability, systematic ability and self-confidence ( P<0.05) . Conclusions:The NSP-based clinical apprenticeship and OSCE for psychiatric nursing is feasible and practical, which can improve students' critical thinking ability, and is worth referencing and promoting.

Objective To evaluate the rehabilitation efficacy of music training in pediatric cochlear implants (CIs).Methods The 14 subjects were divided into the training and control groups.The age of the training group was 5 to 8 years old,with an average of 6.12±1.46.The age of the control group was 5 to 7 years old,with the average of 5.86±0.90.The subjects in the training group received speech rehabilitation training together with music training,while those in the control group only received speech rehabilitation training.We performed an analysis to compare the music perception,speech perception,mental state,and the quality of life between the two groups before and after training.Results For training group,the score of social anxiety scale for children(SASC) was 11± 3.27 before training,and 15.71±1.89 after training;the score of note discriminate test was 30.86±13.61 before training,and 42.29± 13.24 after training.For control group,the scores of SASC was 12.71±2.93 before training,and 14.57±3.51 after training;the pre-training score of note discriminate test was 33.14±11.48,and post-training score was 36.57± 10.44.After training,the scores of the two test items in training group were significantly higher than those in control group (P＜0.05).Conclusion Not only does music training promote music and speech perception in pediatric CIs,it also has proved to be an effective psychological construct for the hearing-impaired children that helps develop self-confidence and improve social status.Moreover,children's improvement in hearing and emotional well-being helps alleviate the psychological stress and anxiety experienced by the children's parents.

Objective To observe the effect of two different chemotherapy regimens, including irinotecan, folinic acid and FU chemotherapy regimen (FOLFIRI) versus folinic acid, FU and oxaliplatin chemotherapy regimen (mFOLFOX6) on nutritional status in patients with advanced colon cancer. Methods A total of 110 patients with advanced colon cancer in Shanxi Cancer Hospital were divided into FOLFIRI (group A) and mFOLFOX6 (group B). To investigate the effect of two different regimens on the patients with advanced colon cancer by toxicity, the traditional methods of nutritional assessment, scored patient-generated subjective global assessment (PG-SGA), nutrition risk screening-2002 (NRS-2002). Shapiro-Wilk was used to detect the normality of small samples, t test was used to analyze measurement data conformed to the normal distribution, Wilcoxon non-parametric test was used to analyze the abnormal distribution data, and enumeration data was detected by using chi-square test. Results The incidence of vomiting, diarrhea and alopecia in group A and group B was respectively 53.8 % (28/52) vs. 29.3 % (17/58), 65.4 % (34/52) vs. 43.1 %(25/58),46.2 %(24/52)vs.20.7 %(12/58)respectively,and there was a significant difference(all P <0.05). The albumin, body mass index, NRS-2002 score, PG-SGA score after chemotherapy were significantly lower than those before chemotherapy in both groups (all P < 0.05). PG-SGA scores after chemotherapy in group A and group B were respectively 7.0 and 5.5 (Z= -2.026, P< 0.05). There were no statistically significant differences between the two groups in the albumin, body mass index, triceps skin fold (TSF), arm muscle weeks diameter(MAMC)and NRS-2002 score(all P >0.05).Conclusions FOLFIRI and mFOLFOX6 scheme can reduce the patient's nutritional status. The probability of gastrointestinal adverse reaction of FOLFIRI regimen is high, which may have an obvious impact on nutritional status of patients compared with mFOLFOX6 scheme.

Objective To discuss differentiated thyroid carcinoma (DTC)postoperative lymph node metas-tasis and clinical use and the effect of 131 I treatment.Methods to185 patients with lymph node metastasis of DTC were selected by random sampling method.The standard 131 I treatment was administrated,ultrasound,CT and Tg chan-ges and imaging characteristics of 131 I treatment were evaluated the clinical curative effect was determined.Results Imaging changes:the whole group of patients,153 patients (82.7%)were effective.153 patients with effective treat-ment,105 cases examined LMDTC completely eliminate (56.8%),48 cases examination revealed narrowing (25.9%).Mere lymph node metastasis after treatment was better than that of patients with viscera metastasis,imaging examination results were statistically significant differences (χ2 =2.57,P =0.02).After treatment,imaging examina-tion result in patients with smaller lymph node was superior to that in the patients with relatively large diameter lymph nodes (P >0.05).Tg level changes:there was a significant reduction in the Tg 97 cases of 185 patients (51.1%), and general decline in 54 patients (29.2%).Tg improvement effect of patients with mere lymphatic metastasis after treatment was better than other viscera metastasis in patients with statistically significant differences (χ2 =3.41,P =0.01).Lymph node Tg improved after treatment in patients with small diameter,which was better than that with other viscera metastasis patients with statistically significant differences(χ2 =6.34,P =0.02).Conclusion Comprehensive curative effect of 131 I treatment of lymph node metastasis postoperatively in patients with DTC is distinct,and is worth popularizing in clinical use of DTC.
