Objective To investigate the application of serum soluble interleukin-2 receptor(sIL-2R)and soluble tumor necrosis factor receptor Ⅱ (sTNFR Ⅱ) in extrapulmonary organ involvement sarcoidosis.Methods Of 28 cases with sarcoidosis which were in active period,12 cases were in extrapulmonary organ involvement subgroup,16 cases were in pure pulmonary lesions subgroup.Serum sIL-2R and sTNFR Ⅱ of the two groups were detected by enzyme linked immunosorbent assay and compared.Results The expression level of sIL-2R in extrapulmonary organ involvement subgroup was (1.60 ± 0.80) μg/L,significantly higher than that of pure pulmonary lesions group,and there was significant difference((1.00±0.29)μg/L,t =2.764,P＜0.05);and the expression level of sTNFR Ⅱ in extrapulmonary organ involvement subgroup was (1.09 ± 0.24) μg/L,significantly higher than that of pure pulmonary lesions group,and the difference between the two groups was statistically significant((0.85±0.29) μg/L,t =2.183,P＜0.05).Conclusion The expression level of peripheral blood serum sIL-2R and sTNFR Ⅱ may serve as the important indexes to judge the extrapulmonary organ involvement sarcoidosis.

ObjectiveTo explore the application of conceive-design-implement-operate (CDIP) teaching modein the training for neurosurgical specialist nurses' core competence. MethodsA total of 76 trainees of neurosurgery specialist nurses in the Second Affiliated Hospital of Soochow University from October 2014 to August 2018 were selected as the research objects. The goal and content of core competence training were formulated by CDIO teaching mode, and the training program was designed and implemented. The results of core competence, general self-efficacy, theoretical assessment and nursing practice assessment before and after training were compared. ResultsThe total score of general self-efficacy of trainees after training was (29.54±5.02), higher than that before training (27.43±4.73), with statistical difference (P＜0.01); the core competencies of trainees after training included critical thinking and scientific research (CR), clinical care (CC), leadership (LD), interpersonal relationship (IR), law and ethics (LE), professional development (PD) and teaching consultation (TC) were (31.29±5.52), (29.11±4.73), (32.08±5.35), (25.78±4.97), (25.72±5.10), (20.13±3.25), (22.37±4.42) respectively, higher than those before training[ (27.33±6.08),(26.93±5.84), (29.32±6.51),(23.13±5.38),(22.92±5.75),(18.87±4.33),(20.72±5.19)]with statistical significance (P＜0.05). The scores of theoretical and nursing practice assessment of trainees after training were (91.96±3.58), (95.17±2.34) respectively, higher than those before training [(78.87±4.96), (83.21±3.98)] with statistical difference (P＜0.01). ConclusionsThe application of CDIO teaching model in the training of neurosurgical specialist nurses can improve students' core competence and general self-efficacy,and provide useful reference for the training of neurosurgical specialist nurses' core competence.

Objective Toinvestigatetheexpressionofsuppressorofcytokinesignaling1(SOCS1)inoverloaded ventricle papillary muscle, so as to understand its expression characteristics in structural remodeling after the overloading and the biomechanical properties of the muscle under cubic jellyfish toxin-1(CfTX-1) pretreatment that can affect cell signal transduction. Methods Abdominal aortic-venous fistula (AVF) were operated in Kunming mice (n=5), and the cardiac left ventricles were harvested after two weeks of fistulation. The mice in normal group were sham operated as a control (n=5). In vitro culture, the left ventricular papillary muscle of normal mice was used (n=20). In the stretching group, the isolated papillary muscles were double-ratio stretched and fixed on silicone plate. In the relaxation group, the muscles were not stretched. A separated subgroup that transfected with SOCS1 plasmids were set in each group of stretching and relaxation. The papillary muscle samples of each group were cultured in culture medium for 3 days at 37 ℃, and then homogenized for extracting total protein. The total protein was separated by 10％ sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The 23 ku band with SOCS1 was used as the target band, and the integrated optical density (IOD) value was measured by computer image analysis method. The expression of SOCS1 protein was detected by Western Blot and the imprinted IOD value was also measured. The papillary muscle in the stretching group was stretched by micro-positioned stretching method, and the initial load was 1 g. After stabilization, the papillary muscle was stretched by 15 mm for continuously 5 times, and the passive tension characteristic curves during the first and fifth stretching were observed and recorded. The peak passive tension (PTmax) and its deceleration velocity (DV) of the papillary muscle were calculated based on the curves. Results Comparing with the AVF group, the normal group had higher IOD values of 23 ku band and SOCS1 blot in total protein of the papillary muscle, and the differences were statistically significant (all P<0.01). The IOD value of 23 ku band in the SOCS1 transfected stretching group was significantly higher than those of the two relaxation groups, and the differences were statistically significant (all P<0.01). However, the difference of this value was not statistically significant between the two relaxation groups. The average IOD value of SOCS1 blot in the SOCS1 transfected stretching group was higher than those of the normal stretching group and the SOCS1 transfected relaxation group, and the differences were statistically significant (all P<0.01). Comparing with the normal group, the AVF group had higher PTmax and ultimate PTmax of the papillary muscles, and had a lower DV values, and the differences were statistically significant (all P<0.01). Conclusions The expression of SOCS1 is sensitive to tension load, and has a positive effect as an overload-sensitive signal in improving myocardial adaptability, protecting myocardial structure and maintaining systolic and diastolic function. CfTX-1 also has a positive effect on improving the compliance of ventricular papillary muscles.

OBJECTIVE: To evaluate the efficacy and safety of autohemotherapy at acupoint for acne. METHODS: Randomized controlled trials (RCTs) regarding autohemotherapy at acupoint for acne were searched in CNKI, WanFang, VIP database and PubMed. According to the inclusion and exclusion criteria, two investigators performed the literature screening, data extraction and basis evaluation, independently. Meta analysis was performed by using Review Manager 5.3 software. RESULTS: Eight RCTs were included, involving 573 patients. The combined effect of effective rate was 1.21 (95% : 1.12, 1.30); the combined effect of skin lesions improvement was -1.00 (95%: -2.14, -0.14, ＝1.73, =0.08); the combined effect of recurrence rate was 0.44 (95%: 0.09, 2.15, ＝1.01, =0.31). CONCLUSION The autohemotherapy at acupoint has better efficacy and skin lesions improvement for acne than control treatment, and autohemotherapy is safer.
