RESUMO
Objective:To investigate the clinical efficacy of neuroendoscopic hematoma removal versus soft channel drainage in the treatment of chronic subdural hematoma. Methods:The clinical data of 102 patients with chronic subdural hematoma who received treatment in Jincheng People's Hospital from May 2018 to May 2020 were retrospectively analyzed. They were divided into the neuroendoscopy group ( n = 50) and the soft channel group ( n = 52) according to different surgical methods. Perioperative indexes, hematoma clearance rate, China Stroke Scale score, the activity of daily living score, and oxidative stress indexes were compared between the two groups. All patients were followed up for 3 months. The incidence of complications during the follow-up period was calculated. Results:The retention time of the drainage tube in the neuroendoscopy group was shorter than that in the soft channel group [(2.45 ± 0.63) days vs. (3.30 ± 0.78) days, t = 6.06, P < 0.001]. The length of hospital stay in the neuroendoscopy group was shorter than that in the soft channel group [(7.14 ± 1.65) days vs. (9.07 ± 2.11) days, t = 5.15, P < 0.001]. The hematoma clearance rate at postoperative 7 days in the neuroendoscopy group was higher than that in the soft channel group [(93.45 ± 5.50)% vs. (81.86 ± 7.24)%, χ2 = 9.12, P < 0.001]. There were no significant differences in operation time and intraoperative blood loss between the two groups (both P > 0.05). At postoperative 30 days, the China Stroke Scale score in the neuroendoscopy group was lower than that in the soft channel group [(12.74 ± 2.23) points vs. (18.67 ± 2.45) points, t = 12.79, P < 0.001]. The activity of daily life score in the neuroendoscopy group was significantly higher than that in the soft channel group [(77.69 ± 7.11) points vs. (91.35 ± 7.25) points, t = 9.60, P < 0.001]. At postoperative 7 days, glutathione peroxidase level in the neuroendoscopy group was significantly lower than that in the soft channel group [(130.75 ± 13.66) U/L vs. (148.60 ± 14.64) U/L, t = 6.37, P < 0.001]. Malondialdehyde level in the neuroendoscopy group was significantly lower than that in the soft channel group [(5.11 ± 0.65) nmol/L vs. (6.19 ± 0.74) nmol/L, t = 7.83, P < 0.001]. Superoxide dismutase level in the neuroendoscopy group was significantly higher than that in the soft channel group [(275.60 ± 22.33) U/L vs. (254.60 ± 18.55) U/L, t = 5.15, P < 0.001]. There was no significant difference in the incidence of complications between the two groups ( P > 0.05). Conclusion:Compared with soft channel drainage, neuroendoscopic hematoma removal can obtain better short-term curative effects and less oxidative stress response in the treatment of chronic subdural hematoma. Neuroendoscopic hematoma removal does not increase the incidence of postoperative complications and is highly safe.
RESUMO
<p><b>OBJECTIVE</b>To study the periodontal health status of Hui and Han adults in Ningxia Hui autonomous region, thus to provide scientific basis for the establishment of oral health care policies in this region.</p><p><b>METHODS</b>2 628 adults in Ningxia Hui autonomous region were investigated in this study according to the criterion issued by World Health Organization on the basic methods of oral health investigation and China oral health third epidemiological survey protocol. The inspection item included gingival bleeding (bleeding on probing, BOP), dental calculus, probing depth (PD) and attachment loss (AL). SPSS 15.0 statistical software was applied to analyze the results.</p><p><b>RESULTS</b>1) The positive rate of BOP sites, detection rate of calculus and PD were peaked in 36-45 and 46-59 years old, but in the > or = 60 age group rather lower. The prevalence of periodontitis and the percentage of AL > or = 4 mm sites were increased with the adults' age. 2) In addition to the percentage of AL > or = 4 mm sites, the differences of the other indicators between the genders were not statistically significant. 3) The positive rate of BOP sites, detection rate of calculus, PD, the prevalence of periodontitis and the percentage of AL > or = 4 mm sites were higher for the mountain areas than the plain areas. 4) Hui population's positive rate of BOP sites, detection rate of calculus, PD, the prevalence of periodontitis and the percentage of AL > or = 4 mm sites were significantly lower than the Han population in Ningxia.</p><p><b>CONCLUSION</b>The periodontal health status of adults in Ningxia Hui autonomous region is associated with age, gender, nationality and region.</p>
