A revolving drum, about 40cm in diameter, with vertical stripes on its surface, was used in examination. The drum was held 50cm in front of the eyes of aircrew receiving examination. The horizontal optokinetic nystagmus was elicited by vertical black stripes moving horizontally. The examinee was instructed to gaze straight ahead at the black stripes, without deliberate fixation. The drum speed was kept constant at 20?, 40?,60?,80?,100?,120?/s. The velocity of the slow component of nystagmus, its frequency, amplitude and symmetry were recorded when the reaction reached its peak.The slow component velocity and the frequency were increased with the drum speed, but the amplitude was decreased with the drum speed. The wave forms of optokinetic nystagmus were usually of five types.

Objective To explore the effect of Taijiquan on motor function and depression in patients with post-stroke depression. Meth-ods From January to October, 2015, 60 stroke patients with depression were randomly divided into control group (n=30) and Taijiquan group (n=30). Both groups accepted routine rehabilitation, while Taijiquan group accepted another training of six actions from simplified Taijiquan. They were assessed with Fugl-Meyer Assessment (FMA), Barthel Index (BI) and Hamilton Depression Rating Scale (HAMD) be-fore, and four and eight weeks after treatment. Results The scores of FMA and BI increased more in Taijiquan group than in the control group after treatment (t>2.351, P<0.05), while the score of HAMD decreased more (t>2.169, P<0.05). Conclusion Taijiquan can relieve the depression and improve the motor and activities of daily living in patients with post-stroke depression.

Objective:To investigate the association between metabolic factors,such as obesity,blood pressure,blood glucose,serum lipid profile,and the histopathological characteristics of renal cell carci-noma.Methods:The medical records of 382 consecutive renal cell carcinoma patients who underwent radical or partial nephrectomy at Peking University People’s Hospital from January 2009 to January 2015 were retrospectively reviewed.Metabolic factors were collected from the records,including weight,body mass index,waist circumstance,blood pressure,fasting blood glucose,serum total triglyceride,serum total cholesterol,serum low-density lipoprotein-cholesterol and serum high-density lipoprotein-cholesterol. The patients were divided into different groups according to tumor grade,stage and diameter.Statistics analysis,such as t test,Mann-Whitney U test and Logistic analysis,were performed to investigate the as-sociation between metabolic factors and grade,stage and tumor diameter of renal cell carcinoma.Re-sults:A total of 80 (20.94%)of the tumors were classified as high grade disease,63 (16.49%)were classified as advanced disease and 153 (40.05%)tumor diameter more than 4 cm.The patients in high grade group were found to have lower high-density lipoprotein-cholesterol level than in low grade group (P =0.015),body mass index,total cholesterol and high-density lipoprotein-cholesterol were found to be lower in advanced disease than in localized disease (P =0.022,P =0.005 and P =0.006,respec-tively),and low-density lipoprotein-cholesterol was found to be lower in larger tumors (P =0.030). Other factors were comparable between the different groups.The results of Logistic analyses showed that, body mass index (OR =0.906,95%CI:0.852 -0.986,P =0.023)and total cholesterol (OR =0.660,95%CI:0.492 -0.884,P =0.005)were associated with the tumor stage,high-density lipopro-tein-cholesterol level was significantly associated with tumor grade (OR =0.293,95% CI:0.108 -0.797,P =0.016)and stage (OR =0.204,95%CI:0.065 -0.635,P =0.006),and low-density lipoprotein-cholesterol level was significantly associated with tumor diameter (OR =0.756,95% CI:0.586 -0.975,P =0.031).Conclusion:The results of our study indicate that metabolic factors,espe-cially obesity and serum lipid profile,are closely related with the histopathological characteristics of renal cell carcinoma.

Objective To study and analyze the nursing intervention of integrated traditional Chinese and western medicine in the treatment of diabetes mellitus complicated with nephrolithiasis. Methods A total of 84 patients with diabetes complicated with nephrolithiasis who were treated from July 2014 to July 2015 were selected as the main study subjects, and they were divided into study group and control group according random number table method, with 42 cases in each group. The control group was given percutaneous nephrolithotomy for western medicine alone, and was given routine nursing care. The observation group was given integrated Chinese and western Medicine and was given comprehensive nursing intervention according to the treatment methods. The changes of blood glucose, 24 h Pro, ALB and incidence rates of complications were compared between the two groups. Results The levels of FBG and 24 h urine, Pr and other indicators in the study group after nursing were significantly better than those in the control group; the incidence rate of complications was also significantly lower than that in the control group, and the difference was statistically significant(P＜0. 05). Conclusion The scientific and effective nursing intervention in integrated traditional Chinese and western medicine in the treatment of diabetes complicated with nephrolithiasis can adjust the blood sugar level and reduce the occurrence of patients' complications.

Objective:To assess the association between warm ischemia time (WIT) and renal function in patients undergoing laparoscopic partial nephrectomy.Methods:A total of 344 patients treated with laparoscopic partial nephrectomy in Peking University People’s Hospital were included. There were 240 males (69.8%) and 104 females (30.2%) with a median age of 57 (23-89) years.The median BMI was 25.6 (16.7-36.0) kg/m 2.213 cases (61.9%) were associated with hypertension.There were 66 (19.2%) patients with diabetes mellitus. There were 92 cases (26.7%) with smoking history. The median preoperative creatinine was 73 (32-170) μmol/L. The median preoperative estimated glomerular filtration rate (eGFR) was 95 (33-142) ml/(min·1.73m 2). The maximum diameter of the tumor was 2.5 (7-9) cm.314 (91.3%) patients with renal cancer stage T 1. All patients underwent warm ischemia during the operation. The patients were divided into three groups for analysis. Restricted cubic spline regression analysis was used to assess the association between WIT as a continuous variable and percentage change of eGFR. Analysis of covariance was used to compare postoperative eGFR among the three groups, and to adjust for preoperative eGFR and tumor diameter. Results:There were statistically significant differences in the percentage change of postoperative eGFR ( P=0.009) and tumor diameter ( P<0.001) among the three groups. Restricted cubic spline regression analysis showed that with the prolongation of WIT, the percentage change of postoperative eGFR gradually decreased, and the curve began to stabilize after 30 minutes (R 2=0.044, P=0.015). The results of covariance analysis showed that after adjusting for baseline preoperative eGFR and tumor size, the effect of WIT on postoperative eGFR was significantly different among the three groups ( F=3.864, P=0.022). The postoperative eGFR in the WIT<20 min group was significantly higher than that in 20 min≤WIT<30 min group( P=0.009) and WIT≥30 min group( P=0.017). There was no significant difference in postoperative eGFR between the two groups with longer WIT( P=0.806). Conclusions:In partial nephrectomy, patients with WIT less than 20 minutes had higher postoperative eGFR levels than those with WIT greater than 20 minutes. However, when WIT exceeded 20 minutes, prolonged ischemia time did not lead to further decline in renal function.

Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

Objective:To investigate the thyroid volume of adults in Lanzhou City, and analyze its influencing factors.Methods:In June 2016, according to the principle of multi-stage stratified cluster sampling, Han residents aged 18 and above in Chengguan, Xigu and Qilihe districts of Lanzhou City who had lived there for more than 5 years were selected as research subjects, and a portable B-ultrasound machine was used for thyroid examination. Morning urine samples of the subjects were collected to test urinary iodine; fasting venous blood samples of the subjects were collected to test serum thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), anti-thyroglobulin antibody (TgAb), blood lipids [triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL)] and blood uric acid (Ua) levels. At the same time, body indexes systolic blood pressure (SP), diastolic blood pressure (DP), waist circumference, height and weight were measured, and the body mass index (BMI) was calculated. Multiple linear regression was used to analyze the influencing factors of thyroid volume.Results:A total of 1 009 subjects were included, aged (43.50 ± 15.16) years, and the thyroid volume was (8.74 ± 3.39) ml. Among them, 534 males had a thyroid volume of (9.46 ± 3.43) ml; 475 females had a thyroid volume of (7.93 ± 3.15) ml, the thyroid volume of males was larger than that of females ( t = 7.36, P < 0.01). Thyroid volume was positively correlated with age, height, weight, BMI, SP, waist circumference, LDL, Ua and TgAb ( r = 0.07, 0.23, 0.33, 0.27, 0.10, 0.27, 0.10, 0.08, 0.07, P < 0.05), and it was negatively correlated with thyroid nodules, TPOAb, TSH and urinary iodine ( r = - 0.16, - 0.07, - 0.10, - 0.08, P < 0.05). After multiple linear regression analysis, TSH, TPOAb, TgAb and thyroid nodules were included in the regression equation, and the standardized B values were - 0.135, - 0.065, 0.123 and - 0.197, respectively. Conclusions:The thyroid volume of males is larger than that of females in Lanzhou City. TSH, TPOAb, TgAb and thyroid nodules are influencing factors of thyroid volume.

Objective:To analysis effectiveness of the "14 plus 7 day quarantine" and "nucleic acid plus total antibody testing" strategy (combined screening strategy) for screenin the imported patients with COVID-19 in Xiamen.Methods:The study populations were overseas travelers arriving in Xiamen from March 17 to December 31, 2020, and overseas travelers who had quarantine outside Xiamen for less than 21 days from July 18 to December 31, 2020. Data were collected and analyzed on the timing of detection, pathways, and test results of the imported patients with COVID-19 after implementing combined screening strategy.Results:A total of 304 imported patients with COVID-19 were found from 174 628 overseas travelers and 943 overseas travelers from other cities. A total of 163 cases (53.6%) were diagnosed by multitime, multisite intensive nucleic acid testing after positive finding in total antibody testing. Among them, 27 (8.9%) were first positive for nucleic acid in 14 plus 7 day quarantine and 136 were first positive for nucleic acid in 14-day quarantine. Only 8 of these individuals were tested positive for nucleic acid after positive total antibody testing. The other 128 individuals were tested positive for nucleic acid after being negative for average 2.3 times (maximum of 6 times). Aditional 155 cases might be detected by using the combined "14 plus 7 day quarantine" and " nucleic acid plus total antibody testing" strategy compared with "14-day quarantine and nucleic acid testing" strategy, accounting for 51.0% of the total inbound infections. So the combined screening strategy doubled the detection rate for imported patients with COVID-19. No second-generation case caused by overseas travelers had been reported in Xiamen as of February 26, 2021.Conclusions:Xiamen's combined screening strategy can effectively screen the imported patients with COVID-19 who were first positive for nucleic acid after 14 day quarantine. Compared with "14 day quarantine and nucleic acid testing", the combined screening strategy improved detection rate and further reduced the risk of the secondary transmission caused by the imported patients with COVID-19.
