Objective To explore the correlation between the total burden of cerebral small vessel disease and poor prognosis of branch atheromatous disease(BAD)in elderly patients.Methods A total of 114 BAD patients admitted to Shanghai Eighth People's Hospital between January 2021 and March 2023 were enrolled,and according to mRS score at 90 d after onset,they were divided into a good prognosis group(mRS score ≤2,67 cases)and a poor prognosis group(mRS score＞2,47 cases).The clinical and imaging characteristics were analyzed,and the relationship between total cerebral small vessel disease burden and clinical prognosis of BAD was investigated using lo-gistic regression analysis.ROC curve analysis was used to determine the threshold of the total cere-bral small vessel disease burden for predicting adverse outcomes and to evaluate its sensitivity and specificity.Results The good prognosis group had younger age,smaller proportion of diabetes,lower SBP,NIHSS score at admission and white matter hyperintensities,and reduced ratio of cerebral microbleeds than the poor prognosis group(P＜0.05,P＜0.01).Statistical difference was observed in the total cerebral small vessel disease burden between the two groups(P＜0.01).Binary logistic regression analysis showed that the total cerebral small vessel disease burden score and NIHSS score at admission were independent predicators of poor prognosis in BAD patients(OR=3.350,95％CI:1.439-7.798,P=0.005;OR=2.814,95％CI:1.586-4.993,P=0.001).ROC curve analysis indicated that the total cerebral small vessel disease burden had a cut-off val-ue of 1.5,and the sensitivity and specificity for predicting poor prognosis was 63.8％and 86.6％,respectively,for BAD patients.Conclusion The total cerebral small vessel disease burden is an in-dependent predictor for poor prognosis of BAD patients.

Objective:To explore the clinical, imaging, and genetic characteristics of an adult patient with sporadic Neuronal intranuclear inclusion disease (NIID).Methods:A patient who had visited the First People′s Hospital of Chenzhou on August 6, 2023 was selected as the study subject. Results of clinical examination, neuroimaging, and genetic testing were retrospectively analyzed along with a literature review. The number of GGC trinucleotide repeats in the 5′-untranslated region of the NOTCH2NLC gene was determined by GC-PCR. Results:The patient had presented with episodic encephalopathy, with enhanced magnetic resonance imaging showing enhancement features of the posterior cerebral cortex during the period of acute episode. Genetic testing revealed an increased number of GGC repeats ( n = 97) in the 5′- untranslated region of the NOTCH2NLC gene, which confirmed the diagnosis of NIID. Conclusion:Clinical attention should be paid to the enhanced MRI findings of patients with adult-onset NIID, for whom posterior cortical enhancement may be characteristic manifestation during the acute phase of encephalopathy-like episode.

Objective:To investigate the intelligence status of children aged 10 - 12 in rural areas of Linxia Hui Autonomous Prefecture (referred to as Linxia) in Gansu Province.Methods:From September to November 2019, a cross-sectional study was carried out to investigate the intelligence status of children aged 10 to 12 in 8 counties (cities) of Linxia. Chinese Raven's Progressive Matrices (rural version) was used for intelligence test and children's intelligence quotient (IQ) was calculated by regular mold to evaluate children's intelligence level.Results:A total of 1 721 children in Linxia were tested for intelligence, with an average IQ of 103.2. Among them, low intelligence (≤69) accounted for 1.0% (18/1 721), borderline (70 - 79) accounted for 3.0% (52/1 721), middle and lower (80 - 89) accounted for 8.4% (144/1 721), moderate (90 - 109) accounted for 56.6% (974/1 721), middle and upper (110 - 119) accounted for 21.9% (377/1 721), excellent (120 - 129) accounted for 7.8% (135/1 721), extremely excellent (≥130) accounted for 1.2% (21/1 721). There were 635, 598 and 488 children aged 10, 11 and 12, respectively, with an average IQ of 106.1, 103.3 and 99.2. There were 919 males and 802 females, with an average IQ of 102.9 and 103.4, respectively.Conclusion:In 2019, the intelligence of children aged 10 to 12 in rural areas of Linxia has reached the moderate level.

Objective:To observe the clinical characteristics of adult patients with ocular toxoplasmosis (OT).Methods:This study was a retrospective clinical trial. Among the 83 consecutive OT patients diagnosed in the Zhongshan Eye Center of Sun Yat-Sen University, 14 patients (16.9%, adult group) aged ≥18 years were included in the study from January 2017 to December 2019. A total of 14 OT patients (children group) aged less than 18 years who had consecutive visits from July to December 2019 were selected as controls. All patients underwent BCVA, slit lamp microscope, fundus color photography, and B-mode ultrasound examination. Eighteen cases underwent UBM examination, including 6 and 12 cases in the adult group and child group respectively; 23 cases underwent FFA examination, including 12 and 11 cases in the adult group and child group respectively. Snellen visual acuity chart was used for BCVA examination, which was converted into logMAR visual acuity in statistics. We compared the two groups of patients' residence (urban or rural), history of contact with dogs and cats, main symptoms, reasons for treatment, course of disease, and clinical and imaging characteristics and so on. For measurement data conforming to normal distribution, t-test was performed for comparison between groups; for Skewness distribution measurement data, rank sum test was performed for comparison between groups. Results:Compared with the adult group and the child group, there was no significant difference in the canine-cat contact history ( Z=2.661, P=0.257) and the time from first diagnosis to diagnosis ( t=-0.186, P=0.351); compared with the children group and the adult group, the patient's living environment was mainly urban, and the course of disease was significantly shorter ( Z=-2.005), and the difference was statistically significant ( P=0.047). The logMAR BCVA of the adult group and the child group were 0.81±1.08 and 2.08±1.30, respectively, and the difference was statistically significant ( Z=-2.811, P=0.004); compared with the child group, the adult group had lighter vitreous opacities, but the difference was statistical significance ( Z=7.847, P=0.048). FFA examination revealed 20 cases of "fern-like" leakage of retinal capillaries. Among them, the adult group and child group were 10 (83.3%, 10/12) and 10 (90.9%, 10/11) cases respectively. Conclusions:Adult patients account for 16.9% of OT patients. Compared with children, adult patients mostly live in towns or cities, have a short course of disease, good vision at first diagnosis, and mild inflammation or hyperplasia of the vitreous cavity. FFA is helpful for the diagnosis of adult OT.

Objective　To investigate the relationship between the level of Lp-PLA2 and the condition as well as prognosis of patients with acute ischemic stroke.Methods　The general data of 120 patients with acute ischemic stroke and 92 healthy persons were collected.The serum Lp-PLA2 levels were detected by ELISA.NIHSS scale was used to assess the severity of the disease at admission.mRS was used to evaluate the prognosis 3 months after discharge.The correlation between serum Lp-PLA2 level and the severity of the disease was analyzed.The risk factors of prognosis were analyzed.Results　The proportion of hypertension and the level of serum Lp-PLA2 in patients with acute ischemic stroke were significantly higher than those in control group (P<0.05).Among 120 patients with acute ischemic stroke,47 cases were mild,38 cases were moderate,and 35 cases were severe.There was significant difference in serum Lp-PLA2 level among the three groups (P<0.05).Pearson correlation analysis showed that serum Lp-PLA2 levels were positively correlated with NIHSS score (P<0.05).Among 120 patients with acute ischemic stroke,81 cases had good prognosis and 39 cases had poor prognosis.The age of patients in poor prognosis group was significantly longer than that in good prognosis group (P<0.05),the time from onset to admission was significantly longer than that in good prognosis group (P<0.05),and serum Lp-PLA2 levels were significantly higher than that in good prognosis group (P<0.05).Multivariate logistic regression analysis showed that age and Lp-PLA2 were risk factors for prognosis of patients with acute ischemic stroke(P<0.05).Conclusion　The higher the level of Lp-PLA2,the more serious the disease is.Lp-PLA2 is a risk factor of prognosis in patients with acute ischemic stroke.

Objective:To explore the nutritional risk status and related factors of elderly inpatients.Methods:Using the convenient sampling method, 321 elderly stroke patients who were hospitalized in the neurology department of a ClassⅢ Grade A hospital from April to October 2018 were selected as the research objects for nutritional risk screening. Serum albumin (ALB) , serum prealbumin (PA) and other related nutritional indexes were recorded, and ADL, tooth, cognition, psychology and sleep of the patients were evaluated.Results:A total of 31.5% (101/321) of elderly stroke patients had nutritional risk. Among elderly stroke patients over 70 years old, 13.39% (43/321) had NRS-2002 ≥ 3 points. There were statistically significant differences in the incidence of nutritional risk among elderly stroke patients of different ages and degrees of dysphagia ( P<0.01) . Correlation analysis showed that the nutritional risk of elderly stroke patients was related to swallowing disorder, activity of daily living, intelligent mental state, and depression state ( P<0.05) . Conclusions:The older the elderly stroke patients, the higher the incidence of nutritional risk. Age, dysphagia, activity of daily living, BMI, intelligent mental state and depression are related to nutritional status, which should be paid attention to by medical staff and timely nutritional intervention should be given.

Objective To explore the relationship between blood lipid levels and cerebrovascular hemodynamic indices (CVHI) in a young and middle?aged population, and to identify reference values for early warning of stroke. Method Between June 2015 and June 2016, a total of 6 252 young and middle?aged patients were assessed for cerebrovascular function in The Health Management Center of Affiliated Hospital of Guizhou Medical University. Patients were divided into abnormal and normal blood lipid groups. Differences in CVHI indicators and scores between the groups were determined, and factors influencing CVHI indices were compared using multivariate logistic regression analysis. Results Mean (Vmean), maximum (Vmax), and minimum blood flow velocity (Vmin) and cumulative scores for CVHI indices in the abnormal blood lipid group were significantly lower than in the normal blood lipid group (P<0.001). However, pulse wave velocity, characteristic impedance, peripheral vascular resistance, dynamic resistance, critical pressure, and differences between diastolic blood pressure and critical pressure were greater than those in the normal blood lipid group (P<0.001). Multivariate logistic regression analysis indicated that a high triglyceride level, overweight or obesity, high systolic blood pressure, high diastolic blood pressure, and age were risk factors for low CVHI scores, with odds ratios (95% confidence intervals) of 1.455 (1.195- 1.771), 2.271 (1.782-2.895), 5.967 (4.557-7.815), 4.251 (3.349-5.396), 2.560 (1.993-3.287), and 1.448 (1.189-1.763). Conclusion Abnormal blood lipid levels can lead to abnormal cerebrovascular function in young and middle?aged population; elevated triglyceride level was an independent risk factor for impaired cerebrovascular function.

Objective To explore the detection trend of vaginal intraepithelial neoplasia(VaIN)of lower genital tract from 2013 to 2015. Methods A retrospective analysis was undertaken of colposcopy-directed biopsy of cervical, vaginal and vulvar intraepithelial neoplasia lesions include cervical intraepithelial neoplasia (CIN), VaIN and vulvar intraepithelial neoplasia (VIN) in Obstetrics and Gynecology Hospital of Fudan University from January 2013 to December 2015. Results (1) Overall data of CIN, VaIN and VIN:a total of 16732 cases were diagnosed of lower genital intraepithelial neoplasia in 3 years, accounting for 23.20% (16732/72128) of total colposcopy-directed biopsy cases. Among them, CIN, VaIN and VIN accounted for 19.48%(14053/72128), 2.67%(1923/72128), 1.05%(756/72128) of total colposcopy-directed biopsy cases of the lower genital tract, 83.99%(14053/16732), 11.49%(1923/16732), 4.52%(756/16732) of total lower genital intraepithelial neoplasia, respectively. (2) Annual data of CIN, VaIN and VIN from 2013 to 2015. The annual proportion of CIN in all intraepithelial neoplasia of lower gential tract was basically stable, consisting of 86.02%(3955/4598),83.25%(4795/5760) and 83.20%(5303/6374), respectively. The annual proportion of VaIN was gradually increasing, consisting of 8.09% (372/4598), 12.45%(717/5760) and 13.08%(834/6374), respectively. The annual proportion of VIN was gradually decreasing, consisting of 5.89% (271/4598), 4.31% (248/5760) and 3.72% (237/6374), respectively. Conclusion The increasing detection of VaIN from 2013 to 2015 might correlate with the increasing attention to inspection of the entire vaginal wall.

Objective To investigate the value of endorectal ultrasonography (ERUS) inpreoperative assessment of rectal cancer post neoadjuvant chemoradiation therapy.Methods From Jan.2016 to Dec.2016,90 rectal cancer patients who underwent preoperative neoadjuvant chemoradiation therapy and total mesorectal excision surgery in the Sixth Affiliated Hospital of Sun Yat-Sen University were retrospectively analyzed,and all patients underwent ERUS examination post neoadjuvant chemoradiation therapy.Of these,64 patients were evaluated by ERUS pre and post neoadjuvant chemoradiation therapy and 26 patients were evaluated only post neoadjuvant chemoradiation therapy.Wilcoxon rank sum test for paired sample was performed to compare the distance from inferior margin of tumor to anal margin,the length and thickness of the tumor pre and post neoadjuvant chemoradiation therapy respectively in rectal cancer.Taken pathologic findings as golden standard,the accuracy of T staging assessed by ERUS post neoadjuvant chemoradiation therapy was evaluated.Results Compared with pre neoadjuvant chemoradiation therapy,the distance from inferior margin of tumor to anal margin significantly increased after neoadjuvant chemoradiation therapy [(58.63±21.71) mm vs (51.68± 19.81) mm],and the length [(26.10± 10.07) mm vs (40.82±9.18) mm] and thickness [(9.73±2.50) mm vs (14.92±5.30) mm] of tumor also evidently decreased post neoadjuvant chemoradiation therapy,respectively (Z were 4.996,6.153 and 6.076,all P ＜ 0.01).The final pathological T stage was pathologic complete response (pCR) or pT0 in 15 patients,pT1 in 3 patients,pT2 in 30 patients and pT3 in 42 patients.The diagnostic accuracy of T staging of rectal cancer post neoadjuvant chemoradiation therapy for ERUS was uT0 82.2％ (74/90),uT1 96.7％ (87/90),uT2 66.7％ (60/90),uT3 67.8％ (61/90) and uT4 96.7％ (87/90),and the overall accuracy was 82.2％ (74/90).Conclusion ERUS could effectively record the morphological changes of rectal cancer pre and post neoadjuvant chemoradiation therapy,which may contribute to the re-evaluation of the distance from inferior tumor margin to anal margin and the range and depth of tumor involvement pre surgical resection.

Objective To investigate the assessment and influencing factors of the cerebrovascular function in 40-60 years old women in Guiyang city,and to provide information for the prevention of stroke in menopausal women.Methods Self-designed questionnaire was used among randomly selected healthy women aged 40-60 years who received health checkup from April 2016 to April 2017 in the Medical Examination Center of Affiliated Hospital of Guizhou Medical University.Levels of height,weight,blood pressure,blood lipid,blood glucose,blood uric acid and the cerebral hemodynamics were checked,comparing the influence of different factors for cerebrovascular function integral value differences,and assess the risk of stroke.Results A total of 439 cases were included in the study,the number of cases with abnormal cerebro vascular function (the score of cerebro vascular function score ＜75) accounted for 13.2％ (58/439).Increased age,being ethnic minorities,menopause,obesity,high blood pressure,high blood sugar,high blood uric acid,increased high-density lipoprotein cholesterol (HDL-C),total cholesterol and triglycerides were related to the abnormal scores of brain function,and the difference was statistically significant (P＜0.05).Logistic regression analysis indicated that minority,High HDL-C [OR(95％CI):0.38 (0.25-0.58),P=0.036],obesity [OR(95％CI):11.62 (5.17-26.14),P=0.001] and hypertension [OR(95％CI):14.87(2.46-89.75),P=0.001] are the factors influencing the cerebro vascular function.Conclusion The proportion of abnormal cerebrovascular function was 13.2％.Increased HDL-C is the protective factor for perimenopausal cerebro vascular function.Minority,obesity and high blood pressure are risk factors for cerebro vascular function,of which,the association between hypertension and cerebro vascular function worsens with elevated blood pressure.
