Objective To investigate the therapeutic effect of different methods of dressing on the wound after local debridement of dia-betic foot. Methods A total of 53 patients which underwent local debridement of diabetic foot were divided into control group and treatment group. Patients in control group were dressed on traditional measurement,while patients in the treatment group were dressed on the external medicinal wine for the diabetic foot basic on the traditional treatment. The local transcutaneous oxygen partial pressure,ulcer healing rate,av-erage healing time and the amputation rate were observed. Results The healing rate and percutaneous oxygen partial pressure of the treat-ment group were significantly increased than those in the control group (P<0. 05). The average healing time and amputation rate of the treat-ment group were significantly less than those in the control group (P<0. 05). Conclusion Dressing on external medicinal wine after local debridement of diabetic foot can improve the wound healing in the diabetic foot.

Objective To explore the value of two-dimensional ultrasound speckle-tracking imaging (STI) in assessing the left ventricular torsion (LVtor) in patients with apical hypertrophic cardiomyopathy (AHCM). Methods Thirty-four patients with AHCM and 21 healthy volunteers underwent two-dimensional echocardiography. High frame rate two-dimensional images of left ventricular short-axis views at the levels of mitral annulus and apex were obtained. Peak rotation (Prot) and the time to Prot, peak rotation velocity on basal and apical plane in left ventricular short-axis views, the peak twist (Ptw) and time to peak twist, half time of untwisting (HTU) were measured using two-dimensional strain software while twisting rate (Untw R) was calculated. All the above indices were compared between patients and healthy volunteers. Correlation was analyzed between HTU and E, A, E/A ratio. Results Compare with healthy volunteers, Prot and time to Prot and peak rotation velocity on apical plane in AHCM significantly increased, so did Ptw and peak rotation velocity of left ventricular (all P<0.05). HTU delayed with the Untw R and peak untwisting velocity decreased in the AHCM group (all P<0.05). There was negative correlation between HTU and E/A ratio in patients with AHCM. Conclusion When the left ventricular systolic function maintained normal in patients with AHCM, the peak rotation on apical plane and the LVtor increased with Untw R decreased. STI can sensitively evaluate the function alteration of myocardium in patients with AHCM.

Objective:To explore the application effect of parent-child emotional regulation and resilience group training in adolescent depression patients.Methods:From August 2020 to September 2021, a total of 118 adolescent depression patients were enrolled and randomly divided into the intervention group(66 cases) and the control group(66 cases) by a random number table method.The intervention group received medication therapy and parent-child group emotional regulation and psychological resilience training, while the control group received medication therapy and commonly used individual, family or group therapy in clinical practice.The Hamilton Depression rating scale(HAMD-24 version), Herth hope scale(HHS), Connor-Davidson resilience scale(CD-RISC), and family adaptability and cohesion evaluation scale, second edition Chinese version(FACES-Ⅱ-CV) were adopted to investigate participants at baseline, 12-week, 24-week, and 36-week after intervention.SPSS 26.0 statistical software was used to perform repeated measurement analysis of variance on the data.Results:(1)The interaction effect between two groups of HAMD scores( F=54.0, P<0.001), group main effect( F=401.4, P<0.001), and time main effect( F=116.6, P<0.001) were all significant.Further simple effect analysis showed that there were statistically significant differences in HAMD scores at various time points after intervention between the intervention group(26.2±6.5, 19.3±5.9, 11.3±5.6) and the control group(33.1±9.1, 30.3±7.9, 25.0±8.4)(all P<0.05). Intragroup comparison showed the HAMD scores of the intervention group and control group at each time point after intervention were lower than those before intervention (all P<0.05). (2)The interaction effect of CD-RISC scores between two groups of patients( F=72.1, P<0.001), group main effect( F=48.9, P<0.001), and time main effect( F=174.9, P<0.001) were significant.Further simple effect analysis showed that the CD-RISC score of the intervention group at each time point after intervention were higher than those of the control group(all P<0.05). Intragroup comparison showed the scores of CD-RISC at each time point after intervention in the intervention group and the control group were higher than those before intervention(all P<0.05). (3)The interaction effect of HHS scores( F=121.6, P<0.001), group main effect( F=57.4, P<0.001), and time main effect( F=208.1, P<0.001) of the two groups of patients were significant.Further simple effect analysis showed that the HHS scores of the intervention group were higher than those of the control group at all time points after intervention(all P<0.05). Intragroup comparison showed the HHS scores of the intervention group and the control group at each time point after intervention were higher than those before intervention(all P<0.05). (4)The interaction effect of FACES-Ⅱ-CV scores( F=45.0, P<0.001), group main effect( F=20.3, P<0.001), and time main effect( F=154.5, P<0.001) of the two groups of patients were significant.Further simple effect analysis showed that the FACES-Ⅱ-CV scores of the intervention group were higher than those of the control group at all time points after intervention(all P<0.05). Intragroup comparison showed the FACES-Ⅱ-CV scores of the intervention group and the control group at each time point after intervention were higher than those before intervention(all P<0.05). (5)The total effective rate of the intervention group was higher than that of the control group(95.1%, 87.7%)( P<0.001). Conclusion:In adolescents with depression, parent-child group emotional regulation and resilience training can effectively reduce depression emotion, increase the level of hope and resilience of patients and enhance family intimacy and adaptability.

Polyetheretherketone (PEEK) as a new type of thermoplastic engineering plastic, has good biological activity, elastic modulus close to human cortical bone and radiation permeability, and has been widely used in medical field. This study aims to explore the safety and clinical efficacy of using 3D printing personalized PEEK materials to repaire scapular bone defects after bone tumor resection. A total of 6 patients who underwent the implantation of 3D printed PEEK scapular prosthesis from January 2020 to December 2021 in Yunnan Cancer Hospital were retrospectively analyzed. There were 3 males and 3 females, with age ranged from 14 to 52 years. There were 1 case of synovial sarcoma, 1 of Ewing's sarcoma, and 4 of chondrosarcoma. PEEK prosthesis was designed and fabricated based on CT data before surgery. Tumor resection and prosthesis replacement were performed under the premise of ensuring safe surgical boundaries, including 2 cases of total scapular prosthesis replacement and 4 cases of partial scapular prosthesis replacement. The operation time was 90-170 min, and the intraoperative blood loss was 100-400 ml. All 6 patients received satisfactory follow-up, with a tumor progression free survival time of 16-28 months. No tumor recurrence or metastasis was observed, and all patients survived tumor free. At last follow-up, the Constant-Murley shoulder joint score was a minimum of 62 points and a maximum of 68 points. The Japanese Orthopaedic Association's shoulder joint score was 63 points minimum and 78 points maximum. Computer-aided design 3D printing PEEK material prosthesis has certain advantages in the treatment of scapular tumor limb salvage. It has light weight, well adapted, relatively simple installation, good histocompatibility, and can obtain a better appearance and function of the shoulder joint after operation. It can become one of the options for limb salvage treatment of scapular tumor.

Objective:To explore the value of adrenocorticotrophic hormone (ACTH) stimulation in adrenal vein sampling (AVS) with its effect on the sampling success rate and lateralization determination.Methods:The clinical data of 54 patients with primary aldosteronism (PA) who underwent AVS in Nanjing Drum Tower Hospital from July 2018 to June 2020 were collected retrospectively. Blood samples from bilateral adrenal veins were collected simultaneously at baseline and after ACTH stimulation. The selectivity index (SI), lateralization index (LI), and relative aldosterone secretion index (RASI) were examined.Results:The concentration of serum cortisol level in left and right adrenal vein and peripheral vein increased significantly after ACTH stimulation ( P<0.001). SI of left adrenal vein increased from 18.00 (2.29, 20.29) to 34.76 (12.10, 46.86) , and the SI of right adrenal vein increased from 26.61(5.24, 31.85) to 28.40 (27.65, 56.05, P<0.001). The bilateral vein sampling success rate increased from 80%(43/54) to 93%(50/54). LI decreased from 2.85(1.78, 6.20) at baseline to 2.45(1.40, 6.10) after ACTH stimulation without significant difference( P>0.05). Eleven patients who identified unilateral secretion at baseline demonstrated bilateral after ACTH stimulation, and the RASI of these patients decreased from 0.50 (0.38, 1.25 ) to 0.37 (0.22, 0.84, P=0.019). Conclusion:ACTH stimulation significantly increased SI and the AVS success rate in patients with PA: ACTH stimulation decreased the relative aldosterone secretion in the dominant side of some patients with aldosterone producing adenoma, thus reduced the proportion of identified unilateral PA.
