Objective To investigate the relationship of benign prostatic hyperplasia(BPH) with abnormal glucose and lipid metabolism in the elderly. Methods A total of 152 elderly patients with BPH were selected as study subjects. The levels of fasting plasma glucose (FPG), 2-hour postprandial glucose (2 hPG), fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), blood uric acid (UA), and prostate-specific antigen (PSA) were measured. Their systolic blood pressure (SBP) and diastolic blood pressure (DBP) were also measured. Prostate volume (PV) and annual prostate growth rate were calculated, and the International Prostate Symptom Score (IPSS) was assessed. Based on blood glucose, blood lipids, and IPSS, the patients were divided into normal blood glucose group(99 cases) and hyperglycemia group(53 cases), normal blood lipid group(112 cases) and dyslipidemia group(40 cases), and moderate symptom group(91 cases) and severe symptom group(61 cases). The clinical characteristics of patients in each group were compared, and the relationships of abnormal glucose and lipid metabolism with the severity of lower urinary tract symptoms in patients with BPH were analyzed. Results Compared with the normal blood glucose group, patients in the hyperglycemia group had higher age, SBP, annual prostate growth rate, IPSS, and levels of FPG, 2 hPG, FINS, and PSA, larger PV, and lower HDL-C level (P < 0.05). Compared with the normal blood lipid group, patients with BPH in the dyslipidemia group had higher age, SBP, annual prostate growth rate, IPSS, and levels of FPG, FINS, TC, TG, LDL-C, and UA, larger waist circumference and PV, and lower HDL-C level (P < 0.05). Compared with the moderate symptom group, patients in the severe symptom group had higher age, BMI, SBP, annual prostate growth rate, and FPG levels, higher incidence rates of hyperglycemia and dyslipidemia, larger PV, and lower HDL-C levels (P < 0.05). Multivariate Logistic regression analysis indicated that age ≥70 years, SBP ≥140 mmHg, hyperglycemia, dyslipidemia, increased PV, and elevated annual prostate growth rate were all independent risk factors for the occurrence of severe lower urinary tract symptoms in patients with BPH (P < 0.05). Conclusion Elderly BPH is closely related to abnormal glucose and lipid metabolism, and abnormal glucose and lipid metabolism are risk factors for the exacerbation of lower urinary tract symptoms.

This study analyzed the anemia status and change trend of 219 835 pregnant women in eight provinces from 2016 to 2020 in the Maternal and Newborn Health Monitoring Program(MNHMP). The results showed that from 2016 to 2020, the anemia rate of pregnant women in eight provinces was 41.27%, and the rates of mild, moderate and severe anemia were 28.56%, 12.59% and 0.12% respectively; the anemia rates in eastern, central and western regions were 41.87%, 36.09% and 44.63% respectively, and the anemia rates in urban and rural areas were 39.87% and 42.23%. From 2016 to 2020, the anemia rate of pregnant women decreased from 44.93% to 38.22%, with an average annual decline of 3.86% (95%CI:-5.84%, -1.85%). The anemia rate among pregnant women of the eastern region (AAPC=-6.16%, 95%CI:-9.79%, -2.38%) fell faster than that among pregnant women of the central region (AAPC=0.71%, 95%CI:-6.59%, 8.57%) and western region (AAPC=-1.53%, 95%CI:-5.19%, 2.28%). From 2016 to 2020, the moderate anemia rate in pregnant women decreased from 14.98% to 10.74%, with an average annual decline of 8.72% (95%CI:-12.90%, -4.34%), with a statistically significant difference (P<0.05); AAPC for mild and severe anemia in pregnant women was 1.56% (95%CI: 3.44%, 0.36%) and 18.86% (95%CI: 39.88%, 9.52%), respectively, without statistically significant difference (P>0.05).

Both anti-glomerular basement membrane (GBM) disease and the anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are common causes of pulmonary-renal syndrome. Organizing pneumonia (OP), a special pattern of interstitial lung disease, is extremely rare either in AAV or anti-GBM disease. We report an old woman presented with OP on a background of co-presentation with both ANCA and anti-GBM antibodies.

This study aims to explore the electrophysiological properties and changes in gene expression of basket cells, a unique population of GABAergic interneurons expressing parvalbumin (PV), during the postnatal development of mouse prefrontal cortex (PFC). Toward this goal, we took use of the G42 transgenic mouse line which specifically expresses enhanced green fluorescent protein (EGFP) in basket cells. The brain slices of PFC were prepared from the postnatal 7 (P7), 14 (P14) and 21 days (P42) G42 mice and whole-cell patch clamp recording was performed in basket cells. In addition, we sorted the basket cells by flow cytometry and analyzed their transcription profiling on P7, P14, and P21 using RNA-seq technology. The results showed that the resting membrane potential and membrane input resistance decreased gradually from P7 to P21. The amplitude and duration of action potential of basket cells increased and decreased from P7 to P21, respectively. In contrast, the threshold of action potential of basket cells did not have a significant change from P7 to P21. The frequency of spontaneous excitatory postsynaptic currents (sEPSCs) of basket cells increased gradually, while the amplitudes of sEPSCs of basket cells remained constant from P7 to P21. RNA sequencing from basket cells revealed that the expression of 22 and 660 genes was upregulated and downregulated from P7 to P14, respectively. By contrast, the expression of 107 and 69 genes was upregulated and downregulated from P14 to P21, respectively. The differentially expressed genes in basket cells from P7 to P21 were significantly enriched in pathways such as neuron apoptotic process, mRNA processing, Golgi vesicle transport and axon guidance. Altogether, we characterized electrophysiological properties and changes in gene expression of basket cells during the postnatal development in mouse PFC. These results provide insight into the mechanisms underlying the development of basket cells in mouse cortex.

Recent population studies have significantly advanced our understanding of how age shapes the gut microbiota.However,the actual role of age could be inevitably confounded due to the complex and variable environmental factors in human populations.A well-controlled envi-ronment is thus necessary to reduce undesirable confounding effects,and recapitulate age-dependent changes in the gut microbiota of healthy primates.Herein we performed 16S rRNA gene sequenc-ing,characterized the age-associated gut microbial profiles from infant to elderly crab-eating maca-ques reared in captivity,and systemically revealed the lifelong dynamic changes of the primate gut microbiota.While the most significant age-associated taxa were mainly found as commensals such as Faecalibacterium,the abundance of a group of suspicious pathogens such as Helicobacter was exclusively increased in infants,underlining their potential role in host development.Importantly,topology analysis indicated that the network connectivity of gut microbiota was even more age-dependent than taxonomic diversity,and its tremendous decline with age could probably be linked to healthy aging.Moreover,we identified key driver microbes responsible for such age-dependent network changes,which were further linked to altered metabolic functions of lipids,carbohydrates,and amino acids,as well as phenotypes in the microbial community.The current study thus demon-strates the lifelong age-dependent changes and their driver microbes in the primate gut microbiota,and provides new insights into their roles in the development and healthy aging of their hosts.

Reversible post-translational modification of proteins is an important process in the physiological regulation of all tissues, including the heart. Lysine acetylation occurs in all organisms, including prokaryotes, and is regulated by a balance between lysine acetyltransferase (adding acetyl to the ε-amino group of lysine) and deacetylase (acetyl group that removes lysine ε-amino group). The heart is an organ rich in acetylated lysine, but the role of acetylated lysine in the heart remains to be elucidated. Therefore, in this paper, we systematically reviewed the gene list of acetyltransferase and deacetylase in mammalian genome and indicated their mRNA expression. The purpose of this study is to discover the research progress of dynamic regulation of lysine acetylation in heart disease and to provide a theoretical basis for the discovery of molecular targets.

Objective: To explore the effect of herb-partitioned moxibustion (HPM) on tight junctions (TJs) of intestinal epithelial cells in Crohn disease (CD) mediated by tumor necrosis factor-α (TNF-α)-nuclear factor kappa B (NF-κB)-myosin-light- chain kinase (MLCK) pathway. Methods: Forty-eight male Sprague-Dawley rats were randomly divided into a normal control (NC) group, a model control (MC) group, an HPM group and a mesalazine (MESA) group, with 12 rats in each group. Trinitrobenzene sulfonic acid (TNBS) was administered to establish CD models. When the model was confirmed a success, the HPM group rats were treated with HPM at Tianshu (ST 25) and Qihai (CV 6), while the MESA group rats were given MESA solution by lavage. When the intervention finished, the colonic epithelial tissues were separated, purified and cultured in each group to establish the intestinal epithelial barrier model in vitro, and TNF-α was added (100 ng/mL) in the culture medium and maintained for 24 h to establish an increased epithelial permeability model. Transepithelial electrical resistance (TEER) was used to examine the permeability of the barrier; Western blot was used to observe the expressions of the proteins related to TJs of intestinal epithelial cells mediated by TNF-α-NF-κB-MLCK pathway; immunofluorescence staining was used to observe the expressions and distributions of tight junction proteins in the intestinal epithelium. Results: After TNF-α induction, compared with the MC+TNF-α group, the TEER value increased significantly in the HPM+TNF-α and MESA+TNF-α groups (both P<0.001); the expressions of nuclear factor kappa B (NF-κB) p65, MLCK, myosin light chain (MLC), tumor necrosis factor receptor-associated factor 6 (TRAF6) and receptor interaction protein-1 (RIP1) decreased significantly (P<0.01 or P<0.05), and the expression of zinc finger protein A20 (A20) increased significantly (P<0.01); the expressions of occludin, claudin-1, zonula occludens protein 1 (ZO-1) and F-actin also increased significantly (all P<0.01). Compared with the MESA+TNF-α group, the expressions of MLC, occludin, claudin-1, ZO-1 and F-actin increased significantly in the HPM+TNF-α group (P<0.01 or P<0.05). Conclusion: HPM can protect or repair the damage of intestinal epithelial barrier in CD rats, which may be achieved through modulating the abnormal TJs in intestinal epithelium mediated by TNF-α-NF-κB-MLCK pathway.
