Objective To explore the incidence and risk factors of perioperative ischemic stroke in non-cardiac and non-neurosurgical surgeries and its correlation with preoperative risk assessment of cerebrovascular events,so as to guide perioperative risk management.Methods A retrospective study was conducted on 40 patients aged≥18 years who underwent non-cardiac and non-neurosurgical surgeries and experienced perioperative ischemic stroke in the First Affiliated Hospital of Henan University of Science and Technology from January 2015 to January 2022,forming the stroke group.A control group of 160 patients without perioperative ischemic stroke was selected in a 1:4 case-control ratio,matched for gender,age,date of operation,and the surgeon.Clinical data and preoperative risk assessment of cerebrovascular events(including the single or combined application of head CT/MRI,transcranial Doppler ultrasound,carotid ultrasound,and neurological consultation)of the two groups of patients were collected and statistically analyzed.Multiple logistic regression analysis was used to identify risk factors associated with perioperative ischemic stroke.Results The incidence of perioperative ischemic stroke was 0.042%.Multiple logistic analysis results showed that hypertension(OR=7.858,95%CI 2.175-28.388,P=0.002),hyperlipidemia(OR=4.457,95%CI 1.320-15.049,P=0.016),renal insufficiency(OR=8.277,95%CI 1.480-46.282,P=0.016),and intraoperative hypotension(OR=3.862,95%CI 1.211-12.317,P=0.022)were independent risk factors for perioperative ischemic stroke in non-cardiac and non-neurological surgeries;preoperative cerebrovascular risk assessment(OR=0.130,95%CI 0.031-0.542,P=0.005)was a protective factor against it.Conclusions The incidence of perioperative ischemic stroke in non-cardiac and non-neurosurgical surgery is low but has a poor prognosis.Hypertension,hyperlipidemia,renal insufficiency,and postoperative hypotension are risk factors for perioperative ischemic stroke,while preoperative cerebrovascular event risk assessment is beneficial to reducing its incidence.

Objective To evaluate the characteristics of different antigen-specific T cell immune responses to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)after inoculation with 2 doses of SARS-CoV-2 inactivated vaccine for 12 months.Methods Fifteen healthy adults were enrolled in this study and blood samples collected at 12 months after receiving two doses of SARS-CoV-2 inactivated vaccine.The level and phenotypic characteristics of SARS-CoV-2 antigen-specific T lymphocytes were detected by activation-induced markers(AIM)based on polychromatic flow cytometry.Results After 12 months of inoculation with 2 doses of SARS-CoV-2 inactivated vaccine,more than 90%of adults had detectable Spike and Non-spike antigen-specific CD4+ T cells immune responses(Spike:14/15,P=0.0001;Non-spike:15/15,P<0.0001).80%of adults had detectable Spike and Non-spike antigen-specific CD8+ T cells immune responses(Spike:12/15,P=0.0463;Non-spike:12/15,P=0.0806).Antigen-specific CD4+ T cells induced by SARS-CoV-2 inactivated vaccination after 12 months were composed of predominantly central memory(CM)and effector memory 1(EM1)cells.On the other hand,in terms of helper subsets,antigen-specific CD4+ T cells mainly showed T helper 1/17(Th1/17)and T helper 2(Th2)phenotypes.Conclusions SARS-CoV-2 inactivated vaccination generates durable and extensive antigen-specific CD4+ T cell memory responses,which may be the key factor for the low proportion of severe coronavirus disease 2019(COVID-19)infection in China.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Objective:To review the categories of physical activities and rehabilitation exercise for aging people based on the theory and method of the International Classification of Functioning, Disability, and Health (ICF). Methods:From the framework and coding of ICF, physical activities, rehabilitation exercise and functional improvement for the aging people were reviewed. Results:There were three typical physical activities: physical fitness, skills and sports, mainly including regular exercises, cognitive amusements, leisure sports activities, recreational sports activities, rehabilitation exercises, etc. Physical activities promoted the functioning of the aging people, including mental function (b1), pain and sensory dysfunction (b2), cardiovascular, blood, the function of the immune system and respiratory system (b4), digestion, metabolism and function of the endocrine system (b5), nerve musculoskeletal function related to movement (b7), the function of skin and related structures (b8), activity (d4), and community, social and civic life (d9), etc., especially body mass index, cardiovascular, physical fitness (muscular strength and endurance, aerobic endurance), balance, flexibility, upper and lower extremities strength, sleep, metabolic capability, cognitive function and anti-aging ability. There were more gains at individual levels, including promotion of subjective happiness, quality of life, reducing depression, risk of sarcopenia, dementia and falling, etc. The environmental and personal factors related to activity and participation in physical activities included the products and technologies (e1), natural environment and man-made changes to the environment (e3), support and interpersonal relationships (e3), attitude, service system and policy (e5), such as urban environment, building environment, street pavement behavior, weather, caregivers, accompany of family and friends, etc. Conclusion:The physical activities and rehabilitation exercise the aged joined include physical fitness activities, skills activities, and sports activities. The physical activities had effects on the rehabilitation of the aged including the function of the body(mental function, pain and sensory dysfunction, cardiovascular, blood, the function of the immune system and respiratory system, digestion, metabolism, and function of the endocrine system, nerve musculoskeletal function related to movement, the function of skin and related structures) and the participation in activities (activities, community, society and civic life). The function of the body works for the health of the aged to promote physical health, mental health, functional health, social adjustment and social well-being.

Objective:To analyze the categories and its relations of recreational physical activities and rehabilitation exercise for adult with disabilities based on the theory and method of International Classification of Functioning, Disability and Health (ICF). Methods:An evidence-based scoping review had been implemented. We had developed the framework and coding approaches for recreational physical activities, rehabilitation exercise and functional improvement for the adults with disabilities based on evidence-based literature review. The literature related to recreational physical activities and rehabilitation exercise of adult with disabilities was searched by subject retrieval method. The retrieval database in Chinese included CNKI and Wanfang database, and the retrieval database in English included PubMed and Web of Science. The retrieval time was from establishment to July 31, 2020. The authors, countries, published time, published journals, research objectives, object of the study and their ages, data collection tool, and the key findings were extracted. Results:A total of 2476 literatures were returned, and 18 of them were enrolled, which were published in 14 countries, and most were published in journals on topics related to medicine, public health, exercise and people with disabilities. They were mainly published from 2010 to 2020, and mainly used questionnaire survey, measurement and interviewing method. There were three typical recreational physical activities: physical fitness activities, skills activities and sports activities, mainly including Taiji Quan, wheelchair basketball, leisure outdoor activities, community recreational sports activities and rehabilitation exercises, etc. According to the framework of ICF, recreational physical activities promote functional rehabilitation for adults with disabilities, including physical functions (b1 mental function; b4 cardiovascular, blood, the function of the immune system and respiratory system; b5 digestion, metabolism and function of the endocrine system; and b7 nerve musculoskeletal function related to movement), and activities and participation (d1 study and application of knowledge; d2 the general tasks and requirements; d4 activity; d5 self-care; d7 interpersonal communication and interpersonal relationship; and d9 community, social and civic life). The evidences showed benefits of improvement in the fields of body mass index, body index, athletic ability, balance ability, and cognitive function. There were more gains at individual levels, including support, coping with stress, self-concept development, life satisfaction, happiness, exercise self-efficacy, health perception, etc. The environmental and personal factors had effects on the performance of activity and participation in recreational physical activities, including e1 products and technologies, e4 attitude, e3 support and interpersonal relationships, e5 service system and policy, as well as attitudes and support of family members and colleagues, interpersonal relationships, social support, transportation, equipment and facilities, and policies. Conclusion:Rehabilitation exercise is an important part of health-related services. We scoped the recreational physical activities and its functional effects for adults with disabilities. The categories and structure of recreational physical activities and rehabilitation exercises were constructed based on ICF. Aligning rehabilitation exercises and relevant factors to ICF, the recreational activities and rehabilitation exercises had been reviewed and discussed and several recommendations for further studies had been drawn.

BACKGROUND: Insomnia is a common complaint that is closely related to gastrointestinal symptoms, which is consistent with the traditional Chinese medicine classical theory of "stomach disharmony leading to restless sleep." Acupuncture is an effective complementary and alternative medicine therapy to improve gastrointestinal function and restore the normal sleep-wake cycle. However, studies on the effectiveness of acupuncture for insomnia due to spleen-stomach disharmony syndrome are limited to case reports and few randomized controlled trials; deeper research on its mechanism is still lacking. This randomized controlled trial aims to assess the treatment efficacy of "harmonizing stomach to tranquilize mind" acupuncture for insomnia and its influence on the intestinal microbiome. METHODS/DESIGN: This is a randomized, single-blind, parallel-group study. Sixty eligible patients with insomnia due to spleen-stomach disharmony syndrome will be randomly divided into two groups (1:1 allocation ratio). The intervention group will use "harmonizing stomach to tranquilize mind" acupuncture, and the control group will receive sham acupuncture. Participants will receive 5 acupuncture treatment sessions per week for 4 consecutive weeks. The Pittsburgh Sleep Quality Index will be used to evaluate the clinical efficacy of acupuncture treatment by making assessments at baseline, the end of treatment and the end of the follow-up. High-throughput 16S ribosomal ribonucleic acid gene sequencing will be performed to detect changes in the intestinal microbial composition before and after treatment. DISCUSSION: The results of this trial are expected to confirm that "harmonizing stomach to tranquilize mind" acupuncture can effectively relieve insomnia and alter the intestinal microbiome.

OBJECTIVE: To establish a novel method to isolate endothelial progenitor cells（EPC） from cryopreserved umbilical cord blood (cryoUCB), to investigate the biological characteristics of EPC and to improve the rate of EPC obtained from cryoUCB. METHODS: Twelve cryoUCB samples during 2000 to 2001 years were collected from allogeneic cord blood bank, cryoUCB was thawed rapidly in a water bath at 37 ℃, total nucleated cells (TNCs) were washed by phosphate-buffered saline (PBS). TNCs were seeded onto fibronectin-coated dishes to isolate EPC. Flow cytometry and immunofluorescence were used to identify EPC. The function of EPC was identified in vitro, such as the incorporation of Dil-Ac-LDL and FITC-UEA-I, the formation of capillary-like structure in matrigel, and the release of VEGF by ELISA. RESULTS: One to five cluster of cobble stone-like cells appeared at 2-3 weeks after seeding. Flow cytometric analysis showed that positive rates of CD31, CD34, CD144, and VEGFR (CD309) were（92.91±5.20）%, （30.0±23.27）%, （88.55±3.83）% and （67.21±12.12）% in passage 1 to passage 3 of EPC. EPC could uptake Dil-Ac-LDL and FITC-UEA-I, form capillary-like network on Matriget and release VEGF. CONCLUSION EPC had been successfully isolated from cryopreserved umbilical cord blood by this method with high stability and reproducibility. EPC can be obtained in 85% frozen umbilical cord blood. This method may lay a foundation to supply abundant EPC for clinical application.

OBJECTIVE: To investigate the clinical significance of bone marrow unclassifiable cells in diagnosis of fever of unknown origin(FUO). METHODS: The clinical data of 60 patients with FUO admitted in the first affiliated hospital of Xi'an Jiaotong university from June 2014 to May 2016 were collected, and 60 patients with FUO were divided into 2 group: group A(30 cases) in which the unclassifiable cells in bone marrow were observed by bone marrow examination, and group B(30 cases) in which the unclassifiable cells in bone marrow not were found by bone marrow examination. The clinical characteristics, bone marrow features, immunophenotypes of bone marrow cells and prognosis of patients in 2 groups were analyzed retrospectively. RESULTS: Out of 30 patients in group A, 18 were diagnosed as malignant tumors including 12 cases of lymphoma, while out of 30 patients in group B, 5 cases were diagnosed as malignant tumor, including 3 cases of lymphoma. For the patients with non-tumor diseases, the bone marrow unclassifiable cells disappeared after the patients condition was improved. CONCLUSION The bone marrow examination including the smear and biopsy shonld be performed routinely for the patients with FUO. If the unclassifiable cells are observed morphologically in bone marrow of patients with FUO, the disease of patients should be considered as malignant tumor, especially, lymphoma.
