Objective To investigate the relationship between serum albumin, bilirubin and cognitive impairment in patients with mild cognitive impairment (MCI). Methods Serum albumin, total bilirubin, direct bilirubin, indirect bilirubin were analyzed in 89 cases of MCI and 82 cases of cognitively normal control. All of the cases underwent neuropsychological testing by Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). The risk factors of MCI were subject to Logistic regression analysis. Results The serum level of total bilirubin in MCI group were significantly lower than that in controls (P < 0.05). There was no significant difference in albumin between MCI and control group (P > 0.05). The bilirubin level was positively correlated with MMSE scores and MoCA scores (including attention, delayed recall and abstract) (P < 0.05), while no significant correlation between serum albumin level and scores of MMSE and MoCA (P > 0.05) by using Spearman correlation analysis. Logistic regression analysis showed that age, education level, diabetes and serum bilirubin levels were independent risk factors for MCI. Conclusion Our data show that decreased serum level of bilirubin is positively related to cognitive impairment.

Objective To investigate Aβ42 and P-tau levels in cerebrospinal fluid (CSF) of patients with mild cognitive impairment (MCI). Methods CSF of 25 cases of MCI and 14 cases of cognitively normal (CN) were investigated. The CSF levels of Aβ42 and P-tau were detected by ELISA method. Correlation analysis was used to analyze the correlation between P-tau level and MMSE score in MCI. Results The CSF level of Aβ 42 was higher and P-tau was lower in MCI than CN group(P<0.05). P-tau level in MCI was also negatively correlated with MMSE score (P<0.05). Conclusion Aβ42 and P-tau levels in CSF may be valuable biological markers in the diagnosis of MCI. P-tau level in CSF of MCI may be related to the severity of cognitive impairment.

Objective:To explore the intervention effect of cognitive-walking dual-task training on executive and walking function in patients with cerebral apoplexy.Methods:A total of 70 stroke patients who were hospitalized in the Department of Rehabilitation Medicine of Baoding Taihe Rehabilitation Hospital from June 2020 to October 2020 were selected as the study subjects.All 70 hemiplegic patients with stroke were randomly divided into control group ( n=35) and test group ( n=35) by random number table method, and a prospective study was conducted.The control group was given routine walking training, and the test group was given cognitive-walking dual-task training at the same time and frequency as the control group.E-Prime software was used to evaluate the executive function of patients before and 4 weeks after intervention, including three sub-tests of Flanker, 1-back and More-odd shifting, and the reaction time of each test was recorded.The score changes of Mini-Mental Status Examination (MMSE) and Modified Rankin Scale (MRS) were recorded.The single-task walking time, dual-task walking time and dual-task walking time cost during 10 m Walk Test were calculated.Finally, 33 cases in the experimental group and 31 cases in the control group completed the study.Finally, 33 cases in the experimental group and 31 cases in the control group completed the study. Results:After 4 weeks of intervention, the MMSE scores of the experimental group and the control group were improved compared with those before intervention (the experimental group (26.39±1.90) and (24.42±2.69), t=10.824, P<0.001; the control group (25.45±1.77) and (24.61±2.16), t=7.325, P<0.001), and the experimental group was significantly better than the control group ( t=2.049, P=0.045)). The duration of three tests of executive function in the experimental group and the control group was significantly shorter than that before the intervention (Flanker task: the experimental group (752.38±178.28) ms and (939.42±260.11) ms, t=10.467, P<0.001; the control group (863.40±227.86) ms and (951.67±265.93) ms, t=8.140, P<0.001.1-back task: the experimental group (983.31±314.16) ms and (1 242.10±444.77) ms, t=10.386, P<0.001; the control group (1 186.89±293.80) ms and (1 238.27±305.95) ms, t=9.569, P<0.001.More odd shifting task: the experimental group (1 121.29±260.17) ms and (1 362.32±352.80) ms, t=13.084, P<0.001; the control group (1 255.81±269.41) ms and (1 351.37±287.46) ms, t=8.550, P<0.001), and the experimental group was significantly better than the control group (Flanker task: t=2.198, P=0.032; 1-back task: t=2.691, P=0.009; more odd shifting task: t=2.044, P=0.045). The results of 10 m walking test in the experimental group and the control group were improved compared with those before the intervention (single task walking time: the experimental group (20.71±9.61) s and (26.10±13.88) s, t=6.312, P<0.001; the control group (22.42±9.60) s and (25.62±10.97) s, t=13.009, P<0.001). The duration of dual task walking: the experimental group (22.73±10.28) s and (31.64±16.07) s, t=7.931, P<0.001; the control group (28.30±11.72) s and (31.89±13.65) s, t=9.348, P<0.001.The cost of dual task walking: the experimental group (10.32±6.87)% and (23.26±11.40)%, t=10.602, P<0.001; the control group (27.39±7.38)% and (24.94±7.48)%, t=2.719, P=0.011). The 10 m walking test time of the experimental group was shorter than that of the control group ( t=2.027, P=0.047), and the walking time cost of the experimental group was lower than that of the control group ( t=9.583, P<0.001). Conclusion:Cognitive walking dual task training can improve the walking function of patients, which is more conducive to the recovery of executive function than conventional walking training.

Objective To investigate the predictive efficiency of combined uterine artery hemodynamic parameters and oxidative stress indicators in early pregnancy on hypertensive diseases in pregnancy (HDP). Methods A total of 90 HDP patients (case group) and 30 healthy pregnant women (control group) as research subjects. The case group included 30 patients with pregnancy-induced hypertension, 30 patients with preeclampsia, and 30 patients with severe preeclampsia, respectively, and were divided into pregnancy-induced hypertension group, preeclampsia group, and severe preeclampsia group. Serum levels of reactive oxygen species (ROS), superoxide dismutase (SOD), heme oxygenase-1 (HO-1), glutathione peroxidase (GSH-PX), malondialdehyde (MDA), and uterine artery hemodynamic parameters were compared between the two groups in early pregnancy (8 weeks to 13 weeks plus 6 days). The receiver operating characteristic (ROC) curve was used to evaluate the predictive efficiency of relevant indicators for HDP. Results The serum levels of SOD and GSH-PX were lower in the case group than that in the control group, and the serum level of MDA and the uterine artery pulsatility index (PI) were higher in the case group than that in the control group (P < 0.05). The serum levels of SOD and GSH-PX gradually decreased, and the serum levels of MDA and PI gradually increased in the pregnancy-induced hypertension group, the preeclampsia group, and the severe preeclampsia group (P < 0.05). The ROC curve showed that the combination of SOD, GSH-PX, MDA, and PI in early pregnancy had a higher predictive efficiency for HDP, with an area under the curve of 0.824, a sensitivity of 81.1%, and a specificity of 76.7%. Conclusion Patients with HDP have changes in oxidative stress indicators and uterine artery hemodynamic parameters in early pregnancy, and there are differences among patients with different disease severities. The combined detection of SOD, GSH-PX, MDA, and PI in early pregnancy can help predict HDP.

A novel technology is proposed for non-contact and real-time detection of atrial fibrillation using millimeter-wave radar.A 60 GHz PCR millimeter wave radar is used to continuously detect the chest echo signal of the subject.After signal acquisition,I-Q signal is generated through I-Q demodulation,and the signal phase information is extracted using effective points phase trend evaluation for obtaining the signals from oscillations in the chest wall,from which the respiratory signals and cardiac signals are extracted through digital filtering for the analysis of cardiac movement.Whether the atrial fibrillation occurs or not is determined by the characteristics of atrial fibrillation wave in the time domain.The effective points phase trend evaluation for extracting more accurate signal phase information and the time-domain method for real-time atrial fibrillation detection are the innovations of the study.The experimental results show that the proposed method achieves a detection accuracy of 99.2%in clinic.

Objective:To investigate the diagnosis, treatment and prognosis of ovarian yolk sac tumor (OYST).Methods:The clinicopathological data and follow-up data of 12 patients with OYST admitted to the Affiliated Hospital of Qingdao University from January 2013 to December 2020 were retrospectively analyzed, and the diagnosis, treatment and prognosis of OYST patients were summarized.Results:(1) The age of 12 patients with OYST ranged from 11 to 37 years, with a median age of 20 years. At the first visit, all 12 patients had pelvic masses. Reasons for seeing a doctor: 6 cases of abdominal distension and abdominal pain, 4 cases of mass in the lower abdomen, 1 case of vaginal bleeding, and 1 case of appendicitis. International Federation of Obstetrics and Gynecology (FIGO) 2014 staging: 4 cases in stage Ⅰa, 2 cases in stage Ⅰc, 1 case in stage Ⅱc, 4 cases in stage Ⅲc, and 1 case in stage Ⅳb. (2) All 12 patients were examined by color Doppler ultrasound before operation, among which 10 cases showed unilateral adnexal masses and 2 cases bilateral adnexal masses. The median maximum diameter of tumor was 16.5 cm (range: 6.0-28.0 cm). The preoperative levels of alpha fetoprotein (AFP) in 12 patients (all >1 210 μg/L) were significantly higher than normal (<25 μg/L). Among the 11 patients with cancer antigen 125 (CA 125) detection results, 9 patients showed elevated serum CA 125 levels. (3) Among the 12 patients, 8 young infertile patients who needed to preserve their reproductive function underwent appendectomy, 3 infertile patients underwent staged surgery for ovarian malignant germ cell tumor, and only one bilateral lesion and infertile patient underwent unsatisfactory staged surgery for ovarian malignant germ cell tumor. Of the 12 patients, 11 patients were given combined chemotherapy regimen of bleomycin, cisplatin, and etoposide (BEP) after operation. One patient without chemotherapy developed metastasis 3 months after operation, and was given BEP chemotherapy, and her condition was controlled. (4) The deadline for follow-up was December 31st, 2022, and the median follow-up time was 60 months (range: 25-115 months). All the 12 patients survived without tumor during the follow-up period, and the median disease-free survival time was 84.5 months (range: 25-115 months). Conclusions:OYST mostly occurs in children and young women. Color Doppler ultrasound examination and serum AFP and CA 125 detection have diagnostic value for OYST. Surgical treatment after diagnosis of OYST includes surgery to preserve reproductive function and timely and standardized chemotherapy after operation. The prognosis of patients is good regardless of stage.

To investigate the effectiveness and safety of ultrasound-guided microwave ablation (MWA) in treatment of primary hyperparathyroidism (PHPT). A total of 12 PHPT patients with parathyroid adenoma were treated with MWA in Nanjing University of Chinese Medicine Affiliated Hospital of Integrated Traditional Chinese and Western Medicine from May 2019 to February 2021. The patients were followed up once every 3 months for 3-12 months. Levels of serum parathyroid hormone (PTH), calcium and phosphorus were detected before and 20 min, 4h and 1day after ablation, and during follow-up period. The volume and volume reduction rate of parathyroid lesion were compared before the treatment and at the end of follow-up. The technical and clinical success of MWA were assessed as well. At the end of follow-up, median serum PTH [66.60 (42.21,80.03) ng/L vs.169.90 (89.01,396.50) ng/L] and calcium [2.39 (2.32,2.49) mmol/L vs. 2.75 (2.57,2.96) mmol/L] levels in 12 patients decreased significantly (all P<0.05). A complete response in terms of PTH and calcium levels was achieved in 6 of the 12 patients, while 4 of the patients had slightly elevated PTH levels just above the upper limit of normal reference range, and 2 of the patients remained abnormal PTH and calcium levels. The clinical cure rate was 50%. The volumes of all lesion after ablation were significantly decreased ( P<0.05), with the technical success rate reaching 92.3%. No serious complications were observed. Ultrasound-guided MWA, thus, is safe and effective in the treatment of PHPT.

As the backbone force of China's social and economic construction, the health status of workers is closely related to the nation's productivity and social development. Currently, cancers have become one of the major diseases threatening the health of workers. However, there are still many shortcomings in the cancer screening services for the workers. To standardize cancer screening services for workers, ensure the quality of screening services, and improve the overall screening effectiveness, 19 institutions, including Peking Union Medical College Hospital of the Chinese Academy of Medical Sciences, have jointly formulated the Group Standard "Specification for service of cancer screening for workers (T/CHAA 023-2023)". This standard follows the principles of "legality, scientific rigor, advancement, and feasibility" and combines the frontier scientific advances in cancer screening. It clarifies the relevant requirements for service principles, service design, service delivery, service management, service evaluation, and improving worker cancer screening. Implementing this group standard will help connect the common screening needs of workers, employers, and cancer screening service providers, standardize the screening process, improve screening quality, and ultimately increase the early diagnosis rate and survival rate of cancer patients. Consequently, this group standard will help safeguard workers' health rights and interests, ensure the labor force resources, promote the comprehensive coordinated and sustainable development of society, and contribute to realizing the "Healthy China 2030" strategic policy.

【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.

【Objective】 Dyslipidemia has shown to be associated with cardiovascular, metabolic and renal diseases. This study aimed to investigate the association between residual cholesterol and the risk of subclinical renal damage (SRD). 【Methods】 A total of 2 342 participants were recruited from the previously established Hanzhong Adolescent Hypertension Study cohort. According to estimated glomerular filtration rate(eGFR) and urinary albumin-to-creatine ratio(uACR), the subjects were divided into SRD group and non-SRD group. The associations of residual cholesterol with eGFR, uACR, and the risk of SRD were analyzed by multiple linear and Logistic regression analyses. 【Results】 Residual cholesterol was positively correlated with uACR(r=0.081, P<0.001) but negatively correlated with eGFR (r=-0.091, P<0.001). Multiple linear regression analysis revealed that residual cholesterol was an influencing factor of uACR (β=0.075, P<0.001) and eGFR (β=-0.027, P<0.001) after adjustment for gender, age, smoke, alcohol, exercise, BMI, hypertension, diabetes and serum uric acid. In addition, Logistic regression analysis revealed that residual cholesterol was significantly associated with the risk of SRD independently of potential confounders [OR(95% CI)=1.387 (1.113-1.728), P<0.001]. Further subgroup analysis showed that residual cholesterol was significantly associated with the risk of SRD in women but not in men. 【Conclusion】 Residual cholesterol is a contributing factor in the risk of subclinical renal damage with gender-specific association.
