RESUMEN
@#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.

Objective This study applied " modified inflation-deflation" to identify the intersegmental plane and explored a method to remove pulmonary segments from the lobe on the basis of cone-shaped principle."Cone-shaped" Segmentectomy includes anatomical separation of the hilum(conical tip) and the intersegmental plane(undissociative conical surface).The feasibility was evaluated.Methods We retrospectively reviewed 146 patients with peripheric pulmonary nodules who underwent cone-shaped segmentectomy between September 2013 and August 2016.Under the guidance of preoperative 3D-CTBA (three-dimensional computed tomography bronchography and angiography)the targeted bronchi and arteries were dissected.The intersegmental plane was identified by " modified inflation-deflation" method.The inflation-deflation interface was anatomically separated from hilum to distal region along the intersegmental veins,while leaving 1-2 cm in thickness from far end.The residual intersegmental parenchyma was then dissected using endo staplers.Mean folhow-up was 20.4 months.Results Sixty two single segmentectomies,38 combined segmentectomies,43 subsegmentectomies and 3 subsubsegmentectonies were performed.Twelve diagnoses of benign nodule,15 diagnoses of atypical adenomatous hyperplasia,6 diagnoses of metastatic carcinona and 113 diagnosis of primary puhmonary cancer were confirmed pathologically." Modified inflation-deflation" spent (12.5 ±6.4)minutes to show the clear inflation-deflation line.All the targeted bronchi and arteries were dissected precisely and the intersegmental veins were preserved.All the preserved adjacent segments kept approximately original shape after inflated.The tumor size was(1.4 ±0.7)cm,the surgical margin width was(2.5 ± 1.6)cm.The depth of the separated intersegmental plane was(4.2 ±1.7)cm,and the width of the plane was(6.5 ± 2.2)cm.The operative time was(158.5 ± 42.6)min,the volume of hemorrhage was(25.2 ± 15.7) ml,the postoperative hospital stay was (5.2 ± 2.2) days.The total incidence of complications was 5.5％ (8/146).No death within 30 days occurred.Among 113 primary pulmonary cancers,there were 35 T0 N0M0(adenocarcinoma in situ) and 78 T1a No M0 non-small-cell lung cancers.One patient had local recurrence,and no death occurred during follow-up period.Conclusion Modified inflation-deflation can show clear inflation-deflation line to identify the intersegmental plane.Thoracscopic cone-shaped segmentectomy can achieve a complete anatomical segmentectomy.

RESUMEN
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.
RESUMEN
ObjectiveTo observe the clinical effect of treating pigmentation after acne with Babai dection mask.MethodsBilateral contrasts was adopted.30 patients who had pigmentation after acnes were randomly recruited into a treatment group and a control group.The treatment group was applied with improved Babai dection mask,while the control group was addminated with honey mask.After 8 weeks of treatment,the therapeutic effects were evaluated.ResultsThe total effective rate of the treatment group was 63.33％,while the control group was 26.67％,showing significant difference (P=0.004).The subjective satisfaction rate of the treatment group was higher than the control group (P=0.002).The melanin value of normal skin and pigmentation after the treatment[the treatment group:(156.18±30.68)、(186.44±41.98); the control group:(158.95± 26.64)、(182.25 ± 44.03)]was dramatically reduced than before the treatment[the treatment group:(180.90±33.09)、(202.37±41.14) ; the control group:(179.92±32.51)、(205.37±43.31)]( P＜0.01).TEWL value of both groups[(13.97 ± 4.78)g/m2h、 (13.57 ± 3.68)g/m2h]were higher than those before treatment[(9.64± 3.01) g/m2h、(10.55± 3.39) g/m2h](P＜0.01).The treatment group (33.72± 9.89) ％ had no change in water capacity than before(35.26± 11.41)(P＞0.05),while the control group decreased[after the treatment:(32.05±10.34)％,before the treatment (37.21±12.24)％].Uv / Ue value of skin elasticity decreased in the treatment group (0.63± 0.05) while no change in the control group (0.64± 0.05).Conclusion Improved Babai dection mask had obvious effects in whitening,accelerating regression of post-inflammatory pigmentation,maintaining the water capacity,and increasing skin elasticity.
