Objective To investigate the risk factors for leukoaraiosis (LA). Methods The clinical and imaging data in patients with stroke were collected retrospectively. LA was divided into periventricular LA and subcortical LA according to the findings of MRI, and they were scored and classified. Results A total of 113 patients with stroke were included. There were 39 women and 74 men (mean age 61.33 ± 1.32 years). The age (65.52 ± 12. 56 vs.47. 96 ±9. 23 years, t =5. 634, P =0. 000), hypertension (68. 60% vs. 29. 63% ,x2 = 12. 932,P =0. 000), diabetes (30. 23% vs. 3.70%, x2 = 7. 953, P = 0. 005), systolic blood pressure (SBP) (147. 42 ± 2. 78 mm Hg vs. 134. 00 ± 22. 45 mm Hg,t = 2. 862, P = 0. 004), glucose (6. 54 ± 3. 48 mmol/L vs. 5. 35 ± 1.37 mmol/L, t = 2. 808, P = 0. 005), and total cholesterol (TC) level (5. 17±0.89 mmol/L vs. 4.59±0.61 mmol/L, t=3. 152, P=0. 002) in patients with periventricular LA (n = 86) were significantly higher than those without periventricular LA (n =27). The age (66. 44 ± 11.33 vs. 47. 96 ±9. 23 years, t =4. 768, P =0. 000), hypertension (74. 29% vs. 34. 88%, x2 = 17. 134, P = 0. 000), SBP (85.46 ± 9. 80 mm Hg vs. 69. 81 ±8. 74 mm Hg, t =2. 999, P=0. 003), diastolic blood pressure (DBP) (85.46 ±9. 80 mm Hg vs.69. 81 ±8.74 mm Hg, t =2. 999, P =0. 003), and TC level (5.22±0.99 mmol/L vs. 4.91 ±0. 75 mmol/L, t =3. 330, P =0. 001) in patients with subcortical LA (n =70) were significantly higher than those without subcortical LA (n =43). Spearman correlation analysis showed that the periventricular LA classification was significantly correlated with the age (rs = 0. 606, P =0. 000), drinking (rs = -0. 257, P = 0. 006), hypertension (rs = 0. 428, P = 0. 000), diabetes (rs =0. 236, P =0. 012), SBP (rs =0. 382, P =0. 000), and DBP (rs =0. 258, P =0. 006). The subcortical LA classification was significantly correlated with the age (rs = 0.488, P = 0. 000),hypertension (rs = 0. 416, P = 0. 000), SBP (rs = 0. 386, P = 0. 000), DBP (rs = 0. 326, P =0. 006), and TC level (rs =0. 231, P =0. 014). Multivariate logistic regression analysis showed that the age (odds ratio[OR] = 1.071, 95% confidence interval [CI] 1.009-1. 137; P=O. 024), hypertension (OR =4. 106, 95% CI 1. 657-10. 174; P =0. 002), and SBP (OR =1. 049,95% CI 1. 162-7. 013; P = 0. 022) were independently correlated with LA. Conclusions The age, hypertension, and SBP are the independent risk factors for LA, in which the age is an uncontrollable factor, and the aggressive prevention and treatment of hypertension may reduce the occurrence of LA.

Objective To analyse the effect of endoscopic thoracic sympathectomy of palma-plantar hyperhidrosis. Methods Between January 2006 and January 2009,77 cases with palma-plantar hyperhidrosis were operated by thoracoscope. Fifty-two cases of palma-axillary-plantar hyperhidrosis were performed sympathectomy of T2-T4 and 25 cases of palma-plantar were performed sympathectomy of T2-T3.Bilateral procedures were completed in the same position. Results After operation palmar hyperhidrosis and armpits hyperhidrosis all were cured. Of soles, 7 cases were completely dry, 34 cases nearly dry, 32 cases unchanged and 4 cases worse. There was no significant difference in the change of plantar hyperhidrosis between sympathectomy of T2-T3 and T2-T4 (P ＞ 0.05). Conclusions Bilateral single port for endoscopic thoracic sympathectomy produces slighter trauma and patients easily accept it. Plantar sweating can be relieved or nearly relieved in partial patients after thoracic sympathectomy. There is no difference in the effect of plantar hyperhidrosis between sympathectomy of T2-T3 and T2-T4.

Objective To investigate the correlation between plasma homocysteine (Hcy) level and cerebral microbleeds (CMBs) band leukoaraiosis (LA) in patients with acute stroke.Methods The clinical and imaging data of patients with acute stroke were analyzed retrospectively.The numbers of CMBs were counted and the severity of LA was graded according to the results of MRI.Fasting venous samples were obtained and the plasma Hey concentration was measured the next day after admission.Results A total of 139 patients with acute stroke were enrolled,67 of them were females and 72 were males (mean age 70.1 ± 10.2 years); 24 had hemorrhagic stroke and 115 had ischemic stroke.The age (76.23 ± 8.74 years vs.64.58 ± 7.42 years;t =4.621,P =0.012) hypertension ratio (89.13％ vs.67.74％ ;x2 =8.324,P =0.0 370) and plasma Hey level (14.53 ± 4.31 mmol/L vs.11.31 ±3.16 mmol/L;t =6.538,P=0.008| in a severe LA group (n=46) were significantly higher than those in a non-severe LA group (n =93).Spearman correlation analysis showed that there was significant correlation between the plasma Hcy level and the severity of LA (rs =0.365,P =0.002).Multivariate logistic regression analysis showed that the increased Hey level (odds ratio [ OR ],1.366,95％confidence interval [ CI] 1.141 - 1.526; P =0.010) and age (OR 1.093,95％ CI 1.031 - 1.162; P =0.016)were the independent risk factors for severe LA.The age (74.37 ± 6.35 years vs.67.56 ± 8.52 years; t =6.628,P =0.038) and hypertension ratio (94.74％ vs.62.20％;x2 =8.773,P =0.002) in a CBM group were significantly higher than those in a non-CMB group (n =82).Spearman correlation analysis showed that there was no significant correlation between the plasma Hcy level and the numbers of CBMs (rs =0.038,P =0.813).Multivariate logistic regression analysis showed that hypertension was an independent risk factor for CBMs.Conclusions The elevated plasma Hcy level was associated with LA,but it was not associated with CBMs.

Objective:To explore the evolution of CT characteristics of the "reversed halo sign" of pulmonary tuberculosis, and to further improve the recognition of its CT signs.Methods:Clinical and CT data of 12 patients with pulmonary tuberculosis who were clinically and pathologically confirmed and accompanied with CT manifestation of "reversed halo sign" in First Affiliated Hospital of Henan University of Science and Technology from August 2013 to April 2020 were analyzed retrospectively. Pathological and imaging contrastl analysis was performed on 1 patient undergoing surgical treatment.Results:Among 12 cases with "reversed halo sign", there were 2 cases with single lesion in unilateral lung, 2 cases with multiple lesions in unilateral lung, and 8 cases with multiple lesions in bilateral lungs. Three cases showed only "reversed halo sign", 9 cases showed both halo-like sign and uniform fireworks sign. "Tree-in-bud "sign was found in all 12 patients in the outer ring of the "reversed halo sign". Eight patients received three or more CT examinations, and six of them showed reduction of density and volume of the "reversed halo sign" after standardized anti-tuberculosis treatment. Under the natural course of the disease in two cases, the overall enlargement of the lesion was observed in 1 case, and the overall density of the lesion was reduced and the outer ring wall of the "reversed halo sign" was thinned in 1 case. The pathology of one case after surgical lobectomy showed granulomatous inflammatory nodules of varying sizes containing Langerhans nodule giant cells in the lung parenchyma. The typical caseous necrotic granulomatous nodules were rare here. The "reversed halo sign" showed dense Langerhans nodules in the outer ring, sparse central areas with fibrous hyperplasia and alveolar wall thickening.Conclusions:The outer ring of "reversed halo sign" of pulmonary tuberculosis shows as "tree-in-bud" sign, and its center shows as the fine reticulation pattern. After effective anti-tuberculosis treatment, both the overall density of "reversed halo sign" and the lesion size reduced. Finally, the lesions mostly present as as fine grid shadows for a long time.
