Objective To treat facial telangiectasia with long-pulse 1 064 nm laser combined with AFT 540 nm photons and to observe the effect.Methods The disease was treated with composite vascular therapeutic apparatus of Alma laser.According to skin type and treatment response,the different energy density and pulse width were chosen in the treatment.Results After 4-6 times of treatment,the totally effective rate in 60 cases was as high as 100%without scar formation and pigmentation.Conclusion Treatment of facial telangiectasia with long-pulse 1 064 nm laser plus AFT540nm photons is safe and effective.

Objective To evaluate the correlation between sonographic features of papillary thyroid microcarcinoma(PTMC) and cervical lymph node metastasis.Methods Preoperative sonographic features of 379 papillary thyroid microcarcinoma in 341 patients were retrospectively reviewed,and were divided into two groups,lymph node metastasis and lymph node non-metastasis according to pathology.Univariate and multivariate analyses were performed to analyze the sonographic features relevant to lymph node metastasis.Results Univariate analysis revealed that unclear border,microcalcification and multifocal PTMC were statistically significant(all P ＜0.05).Multivariate analysis revealed that microcalcification and multifocal PTMC were statistically significant (both P ＜0.05).Conclusions Microcalcification and multifocal PTMC are closely relevant to cervical lymph node metastasis.

Objective:To design an assisted lip retraction breathing exercise tool and observe its application in home-based pulmonary rehabilitation of patients with chronic obstructive pulmonary disease(COPD). Method:A total of 116 COPD patients treated at our hospital from January 2020 to January 2021 were select-ed as study subjects and divided into the control group(n=58)and the observation group(n=58)using a ran-dom number table method.The control group was given conventional inhalation medication and lip retraction breathing training instruction,and the observation group was given an assisted lip retraction breathing exercise tool to assist lip retraction training on the basis of the control group.The pulmonary function,arterial blood gas,6-minute walk distance(6MWD),modified British medical research council(mMRC),body mass in-dex,obstruction,dyspnea,exercise capacity index(BODE index)and patient satisfaction were compared be-tween the two groups at l month,3 months,and 6 months after discharge from the hospital. Result:After 3 and 6 months of exercise,the pulmonary function(FVC,FEV1)of the observation group were better than those of the control group(t=2.196,2.613,3.022,4.200 P＜0.05),and arterial blood gas(PaCO2,PaO2)were better than the control group(t=5.223、11.536、2.086、2.223 P＜0.05),6MWD was higher than the control group(t=10.725,11.620 P＜0.05),mMRC was lower than the control group(t=10.110,22.567 P＜0.05),BODE index grade 1(17.24％,34.48％)and grade 2 rates(37.93％,48.28％)were higher than the control group(10.34％,6.90％,25.86％,27.59％),and grade 3(25.86％,17.24％)and grade 4 rates(18.97％,0)were lower than the control group(31.03％,34.48％,32.76％,31.03％)(Z=-2.060,35.273 P＜0.05),the satisfaction rate of patients in the observation group was 91.38％(53/58)at 1 month of exercise,96.55％(56/58)at 3 months,and 100％(58/58)at 6 months. Conclusion:The assisted lip retraction breathing exercise tool can improve the home-based pulmonary rehabilita-tion,enhance exercise endurance,reduce the severity of dyspnea,and improve patient satisfaction.

Objective:To observe the application effect of a self-designed assisted abdominal breathing rehabilitation device in elderly patients undergoing postoperative chemotherapy for lung cancer.Methods:Self-designed an assisted abdominal breathing rehabilitation device. Used the convenience sampling method, 116 elderly patients admitted to the First Affiliated Hospital of Anhui Medical University from April 2021 to April 2022 undergoing postoperative chemotherapy for lung cancer were selected as study subjects, and they were divided into control and observation groups by the random number table method, with 58 cases in each group. The control group received routine abdominal breathing training, and the observation group used auxiliary abdominal breathing rehabilitation device for abdominal breathing training, and compared the training compliance rate, lung function indexes and six minutes-walk test scores of the two groups before and after 2 weeks of training.Results:After 2 weeks of training, the training compliance rate of patients in the observation group was 100.00% (58/58), which was higher than 87.93% (51/58) in the control group, and the difference was statistically significant ( χ 2=7.45, P<0.05). After 2 weeks of training, FEV 1, FVC, FEV 1/FVC were (1.81 ± 0.29) L, (1.98 ± 0.32) L, (91.91 ± 5.98) % respectively in the observation group, and (1.49 ± 0.31) L, (1.73 ± 0.41) L, (87.11 ± 9.44) % respectively in the control group, there were statistically significant differences between the two groups ( t=-4.13, -2.60, -2.36, all P<0.05). After 2 weeks of training, the six minutes-walk test score was (0.86 ± 0.71) points in the observation group and (1.02 ± 0.74) points in the control group, and the difference was statistically significant ( t=2.05, P<0.05). Conclusions:An assisted abdominal breathing rehabilitation device helps to improve the training compliance rate, enhance lung function recovery and improve exercise endurance in elderly patients undergoing chemotherapy after lung cancer surgery.
