ABSTRACT
ObjectiveTo investigate the effect of different levels of physical activity on the risk of Parkinson's disease (PD). MethodsA total of 9 726 subjects from 2018 China Health and Retirement Longitudinal Study (CHARLS) data were analyzed with multivariate Logistic regression analysis. ResultsOf the 9 726 subjects, 188 suffered from PD, with a prevalence of 1.93%. The subjects who aged more than 65 (OR = 2.58, 95%CI 1.74 to 3.96, P < 0.001) and widowed (OR = 1.42, 95%CI 1.01 to 1.99, P = 0.043) were at a higher risk of developing PD. Subjects who engaged in high-intensity physical activities (OR = 0.38, 95%CI 0.27 to 0.54, P < 0.001) were at a lower risk of PD. After adjusting for age and marital status, high-intensity physical activity still reduced the risk of PD (OR = 0.42, 95%CI 0.29 to 0.61, P < 0.001). ConclusionHigh-intensity physical activity (over 3 000 metabolic equivalents a week) may reduce the risk of PD.
ABSTRACT
The detection of early lung adenocarcinoma manifesting as ground glass nodule (GGN) is increasing. The promoting precision targeted therapy arises the need of radiomics (RM) and radiogenomics, a series of noninvasively radiological technology based on multiple modality, to assist the process including determination in diagnosis, treatment and follow-up strategy and release burden in clinical practice. RM, playing an important role in lung adenocarcinoma manifesting as GGN, can provide information towards the different components of the nodules, the analysis of peritumoral areas, the reduction of over diagnosis and treatment, the selection of targeted therapy and follow-up.
ABSTRACT
It is well known that an unhealthy lifestyle is a major risk factor for metabolic diseases, while in recent years, accumulating evidence has demonstrated that the gut microbiome and its metabolites also play a crucial role in the onset and development of many metabolic diseases, including obesity, type 2 diabetes, nonalcoholic fatty liver disease, cardiovascular disease and so on. Numerous microorganisms dwell in the gastrointestinal tract, which is a key interface for energy acquisition and can metabolize dietary nutrients into many bioactive substances, thus acting as a link between the gut microbiome and its host. The gut microbiome is shaped by host genetics, immune responses and dietary factors. The metabolic and immune potential of the gut microbiome determines its significance in host health and diseases. Therefore, targeting the gut microbiome and relevant metabolic pathways would be effective therapeutic treatments for many metabolic diseases in the near future. This review will summarize information about the role of the gut microbiome in organism metabolism and the relationship between gut microbiome-derived metabolites and the pathogenesis of many metabolic diseases. Furthermore, recent advances in improving metabolic diseases by regulating the gut microbiome will be discussed.
ABSTRACT
Objective:To observe whether parathyroid hormone (PTH) 1-34 can block the negative osteogenesis of advanced glycation end products (AGEs) on bone marrow mesenchymal stem cells (BMSCs) in rats and its possible signaling pathways.Methods:BMSCs from 4-week-old SD rats were isolated and cultured with whole bone marrow method. The osteogenic induction fluid, bovine serum albumin(BSA), AGEs, AGEs combined with PTH1-34 were pretreated respectively. After 7 days, realtime fluorescence quantitative PCR (RT-PCR) was used to measure alkaline phosphatase (ALP), collagen-Ⅰ (COL-Ⅰ) mRNA expression level, and the expressions of β-catenin, osterix (OSX), runt-related transcription factor 2 (RUNX2), and receptor for advanced glycation end products protein were examined by Western blotting. Alizarin red staining mineralized nodules and quantitative detection were performed on 21 days. After the addition of Wnt pathway specific blocker Dickkopf-1 (DKK1) (1 μg/ml) to 10 -8 mmol/L of PTH1-34, the protein expression levels of β-catenin, OSX, and RUNX2 were detected again by Western blotting. Results:AGEs significantly inhibited the expression of ALP, COL-Ⅰ mRNA, β-catenin, OSX, and RUNX2 proteins ( P<0.05). PTH1-34 inhibited AGEs after pretreatment, the expression of ALP, COL-Ⅰ mRNA, and β-catenin, OSX, RUNX2 protein were higher than those of AGEs group ( P<0.05). The mineralized nodules stained with alizarin red showed reddish brown and increased OD value was detected quantitatively in PTH1-34 group, which was higher than that of AGEs group ( P<0.05). DKK1(1 μg/ml) reduced the expression of β-catenin, OSX proteins as compared with the BSA group ( P<0.05). Conclusion:PTH1-34 blocks AGEs′ negative osteogenesis to BMSCs through Wnt/β-catenin signaling pathway.
ABSTRACT
Human milk oligosaccharides (HMOs) are the third largest solid component in human milk,followed by lactose and lipids.The importance of HMOs to infants has attracted more and more attention.The core structure of HMOs consists of galactose (Gal),glucose (Glc),N-acetylglucosamine (GlcAc),fucose (Fuc) and sialic acid (Sia) derived N-acetylneuraminic acid (Neu5Ac),which link with different groups that have different effects.HMOs could be used as prebiotics to regulate intestinal flora,as antiadhesives to resist pathogen adhesion,and as modulators of cell responses to regulate cellular inflammation.Through the mechanisms above,HMOs can affect many aspects of infant growth and development,such as relieving diarrhea,preventing respiratory infections,alleviating allergies,interfering with obesity,and even affecting the acquired immunodeficiency syndrome.This article will explain the structure of HMOs,the metabolism inside human body and the definite mechanism of action in process of infantile development and describe some related diseases.
ABSTRACT
Efforts to preserve β-cell mass in the preclinical stages of type 1 diabetes (T1D) are limited by few blood-derived biomarkers of β-cell destruction. Platelets are proposed to be the sources of blood-derived biomarkers for a variety of diseases, and they show distinct proteomic changes in T1D. Thus, studying these proteomic changes may provide us with biomarkers of β-cell destruction. This paper is the Chinese translation of " Exocytosis protein DOC2B as a biomarker of type 1 diabetes" , published on " The Journal of Clinical Endocrinology & Metabolism" in May 2018 [Aslamy A, Oh E, Ahn M, et al. J Clin Endocrinol Metab, 2018, 103(5): 1966-1976] after obtaining the copyright from the original journal. This study aimed to investigate the changes in the exocytosis protein double C2 domain protein-β (DOC2B) in platelets and islets from T1D humans, pre-diabetic NOD mice, and from T1D patients after islet transplantation. The results showed that the DOC2B protein abundances were substantially reduced in platelets of prediabetic NOD mouse and new-onset T1D patients, while platelet DOC2B levels were increased after islet transplantation in T1D patients. Thus, reduction of DOC2B is an early feature of T1D, and DOC2B abundance may serve as a valuable in vivo indicator of β-cell mass as well as an earlier biomarker of T1D.

ABSTRACT
One-hour post-load glucose concentration (1hPG) ≥155 mg/dl (8.6 mmol/L) in individuals with normal glucose tolerance (NGT) was correlated with increased risk for type 2 diabetes mellitus. This paper is the Chinese translation " One-hour post-load hyperglycemia: implications for prediction and prevention of type 2 diabetes" , published on " The Journal of Clinical Endocrinology & Metabolism" [ Fiorentino TV, Marini MA, Succurro E, et al. J Clin Endocrinol Metab, 2018,103(9):3131-3143] after obtaining the copyright of the original journal. In this review, the authors analyzed the role of 1hPG measurement in prediction of type 2 diabetes and cardiovascular disease. They used MEDLINE and included all English studies published up to February 2018 in peer-reviewed journals that examined the relationship between 1hPG and diabetes, cardio-metabolic alterations, organ damage, and cardiovascular disease. The results showed that although 1hPG was not adopted by American Diabetes Association for identifying high-risk individuals, the available evidence indicated that, among subjects with NGT, a value of 1hPG≥155 mg/dl is helpful to identify those at increased risk of type 2 diabetes and cardiovascular disease.
ABSTRACT
Objective To investigate the possible causes of surgical site infection(SSI)in neurosurgical patients in a hospital during a short period of time.Methods Medical data of 135 neurosurgical operative patients from February 1 to March 15,2013 were reviewed,the possible risk factors for SSI were analyzed retrospectively with case-control study.Results Of 135 operative neurosurgical patients,5 (3.70%)developed SSI.Case-control study showed that the ratio of the run of the fifth operating room and undergoing of secondary operation was 4.07 (95%CI :0.52 -36.65)and 18.00(95%CI :2.00 -180.00)respectively.The difference between each surgeon special SSI rate and the average SSI rate in 2012 (2.54%[17/669])was not significantly different (P >0.05).Bacterial detection of en-vironmental specimens of the fifth operating room showed that except anesthetic cuff exceeded standard,the others were met the national requirements,and the isolated bacteria from anesthetic cuff was coagulase negative Staphylo-coccus ,which was not related with pathogens in infection.Conclusion “The secondary surgery”is the key risk fac-tor for SSI of neurosurgical patients.
ABSTRACT
ObjectiveTo explore the influencing factors of mechanical ventilation time in esophageal cancer patients with lung infection after operation.Methods55 esophageal cancer patients with lung infection after operation requiring endotracheal intubation or tracheostomy and mechanical ventilation were included.According to duration of mechanical ventilation time, ＜ 7 days for early weaned from ventilator group, ＞ 7 days for late weaning group.60 esophageal cancer patients with lung infection after operation without mechanical ventilation served as controls.Various factors on the impact of mechanical ventilation were compared.ResultsEarly and late weaning patients were older than control group(P ＜ 0.05), particularly in late weaning patients(P ＜ 0.01).Compared with the control, FEV1 and MVV decreased significantly in early weaning patients(P ＜ 0.05).NFGNB infection in late weaning patients significantly increased than in early weaning patients and the control(all P ＜ 0.01).Logistic multivariate analysis showed that FEV1 was independent factors affecting early weaning (P ＜ 0.01), age (P ＜ 0.05) and NFGNB infection (P ＜0.01) affecting late weaning.ConclusionThe influencing factors of mechanical ventilation time in esophageal cancer patiens with lung infection after operation were FEV1 decreasing,age and NFGNB infection.
ABSTRACT
Objective The patient started from St. Louis (U. S.), and reached Chengdu (China) after 3 days of flight(St. Louis- Tokyo- Beijing - Chengdu). The patient felt unwell, so he and the two relatives took a taxi to the Emergency Center of Sichuan Provincial People' s Hospital for treatment. The epidemiological survey showed that, the patient had been living in the University of Missouri in the United States, no pigs died locally, there were no markets for the living pigs, farmers markets, farms, and slaughterhouses, and he hadn't contact with pigs. But 4 days before the onset, he closely contacted with a schoolmate, who had cold symptoms. The pa-tient had never been to virus laboratory 7 days before the onset. Clinical examinations showed that, the patient had a fever (37.8 ～ 38.8℃), WBC 7.9×10-9 L-1, N 5.475 × 10-9 L-1, L 19.5% ;the chest X-ray shewed that texture increased and the heart shadow augmented on both lungs; the result of throat swab culture was negative. The result of virus nucleic aeid detected by Sichnan Provincial Center for Disease Control showed H1N1 influenza virus, suspected. Sichuan Province Health organization organized experts on the prevention and control of H1N1 influenza for consultation, and the patient was diagnosed as the first suspected H1N1 influenza case in mainland China based on the epidemiological investigation, symptoms and signs of the patient, the results of laboratory ex-amination, and the result of virus test. Confirmed by the experts from Chinese center for disease control and pre-vention and The Ministry of Health of the People's Republic of China, the patient was diagnosed as the first H1N1 influenza case in mainland China.
ABSTRACT
Wound secretion from 20 patients with gaseous gangrene was collected for Gram staining,bacterial culture and drug sensitivity tests.The results indicated that gaseous gangrene was caused by the co-infection of both aerobic and anaerobic bacteria.Gram-negative bacilli were slishtly more common than other aerobic bacteria in gageous gangrene wound,which was different from the findings of ordinary gaseous gangrene.
