Objective To explore the mechanism of blood-stage treatment in patients with psoriasis vulgaris through studying the level change of IFN-?, IL-4, IL-10 and IL-17 in patients with blood-stage treatment during activity and quiescence period separately. Methods 20 patients with psoriasis vulgaris in active stage(blood heat syndrome)and 20 patients with psoriasis vulgaris in resting stage(blood stasis syndrome) were recruitedto observe the treatment effects by the PASI score,and to observe thechange of IFN-?, IL-4, IL-10, IL-17 before and after treatment in the serum by ELISA. Results The PASI scores of two groups were both significantly decreased after treatment (blood heat syndrome group t=6.685, P<0.01;blood stasis syndrome group t=4.959, P<0.01). The levels of cytokines were significantly different between patients in the periods of activity and quiescence. Onvarying degrees, the levels of cytokines of two groups were improved after treatment. The levels of cytokines IFN-?, IL-17 in blood heat group significantly decreased(t=3.024, P<0.01;t=2.543, P<0.05). The levels of cytokines IL-17 drop but the levels of cytokines IL-4 raised in blood stasis group,that were significantly differentwith the levels before treatment(t=2.417, P<0.05; t=2.547, P<0.05). Conclusion The levels of INF-?, IL-4, IL-10 and IL-17 could be effectively modulated with blood-stage treatment in treating psoriasis vulgaris.

Objective:The topographical mapping technique of cortical evoked potential was used to observe the changes of the functional activities in the primary somatosensory area of cortex (SI) during external stimulation,the immanent relation between external stimulation and topographical mapping of cortical somatosensory evoked potential (CSEP). Methods:33 healthy adult volunteers were under observation. Cerebral electric signal processing system was used to lead CSEP on the scalp. The external stimulation was applied as following:①A soft paintbrush was used to slightly brush the face only. ②Paintbrush was used to slightly brush the lower limb only. ③Paintbrush was used to slightly brush the trunk only. ④Paintbrush was used to slightly brush the lower limb or the trunk or the Gallbladder Meridian (GBM) and passing the upper arm by imitating the speed of meridian transmission phenomenon respectively. Results:①Evoking responses appeared in the foot areas in SI,without meridian transmission phenomenon when brushing the face,lower limb or trunk only. ②Healthy volunteers were offered imitation of sensation conduction along the GBM as well as brushing through the upper arm in addition,while,the results showed that the evoking responses appeared in the foot,the upper arm and the face representation area of SI simultaneously. Conclusion:The external stimulation along the meridian course was able to change the distribution of evoking responses in SI during stimulating acupoint. But the local stimulating on face,lower limb or trunk can not change the distribution of CSEP. The results provided experimental evidence for the supposition that 'activation in sequence in periphery'was the decisive factor for the formation of meridian transmission phenomenon.

Objective To explore the feasibility and clinical value of free-of-puncture positioning in three-dimension-guided anatomical segmentectomy for ground-glass nodule (GGN) compared with percutaneous positioning. Methods Clinical data of 268 enrolled patients undergoing anatomical pulmonary segmentectomy from October 2018 to June 2019 were retrospectively collected, including 75 males and 193 females with an average age of 56.55±12.10 years. The patients were divided into two groups, including a percutaneous positioning group (n=89) and a free-of-puncture positioning group (n=179). Perioperative data of the two groups were compared. Results The average CT scan times of the percutaneous positioning group was 3.01±0.98 times, and the numerical rating scale (NRS) score of puncture pain was 3.98±1.61 points. Pulmonary compression pneumothorax (≥30%) occurred in 7 (7.87%) patients and intercostal vascular hemorrhage occurred in 8 (8.99%) patients after puncture. Lung nodules were successfully found and removed in both groups. There was no statistically significant difference between the two groups in the location of nodules (P=0.466), operation time (151.83±39.23 min vs. 154.35±33.19 min, P=0.585), margin width (2.07±0.35 cm vs. 1.98±0.28 cm, P=0.750), or the number of excised subsegments (2.83±1.13 vs. 2.73±1.16, P=0.530). Conclusion Anatomical segmentectomy with three-dimensional navigation avoids the adverse consequences of puncture, which has the same clinical efficacy and meets the requirements of oncology compared with percutaneous positioning. The free-of-puncture positioning method can be used for GGN located in the central region of pulmonary segment/subsegment or adjacent to intersegment veins instead of percutaneous positioning.
