Biomarkers of cognitive impairment in patients with cerebral small vessel disease / 国际脑血管病杂志

Cerebral small vessel disease (CSVD) is the main cause of vascular cognitive impairment. Its mechanism is not yet fully clear, which may be associated with vascular endothelial dysfunction and the destruction of blood-brain barrier. In recent years, some studies have been conducted on biomarkers of cognitive impairment in patients with CSVD. This article reviews the biomarkers of cognitive impairment in patients with CSVD from the aspects of inflammatory response, oxidative stress, vascular endothelial dysfunction, endocrine, nervous system damage, and microRNAs.

Effect mechanism of blistering moxibustion on visceral hypersensitivity of irritable bowel syndrome in mice based on 5-HT signal pathway / 中国针灸

OBJECTIVE@#To observe the effect of blistering moxibustion on the expression levels of 5-hydroxytyptamine (5-HT) and its receptors of the colon tissue in the mice with visceral hypersensitivity of irritable bowel syndrome (IBS), so as to explore the effect mechanism of blistering moxibustion in treatment of IBS.@*METHODS@#Forty SPF-grade newborn Kunming mice were randomly divided into a normal group, a model group, an antagonist group and a blistering moxibustion group, 10 mice in each one. Before modeling, the injection with 0.2 mL parachlorophenylalanine (PCPA) was given on the lateral ventricle in the antagonist group. The endorectal glacial acetic acid stimulation combined with tail clipping was used to prepare the model of visceral hypersensitivity of IBS in the model group, the antagonist group and the blistering moxibustion group. After modeling, in the blistering moxibustion group, the intervention with blistering moxibustion was exerted at "Zhongwan" (CV 12), "Tianshu" (ST 25) and "Zusanli" (ST 36), once herbal irritant plaster at each acupoint, for 2 h each time, once a week, consecutively for 3 weeks. Abdominal withdrawal reflex (AWR) score and electromyographic (EMG) amplitude of abdominal muscles were adopted to evaluate the visceral hypersensitivity. HE staining was applied to observe the morphological changes in colon tissue, and immunohistochemistry was to determine the expression levels of 5-HT and its receptors.@*RESULTS@#Compared with the normal group, EMG amplitude of abdominal muscles was increased under 20, 40 mm Hg (1 mm Hg=0.133 kPa) in the model group (P<0.05), AWR scores and EMG amplitude of abdominal muscles under 60, 80 mm Hg were all increased in the model group (P<0.05). In comparison with the model group, EMG amplitude of abdominal muscles was reduced under 20 mm Hg in the blistering moxibustion group (P<0.05), AWR scores were increased under 40 mm Hg in both the blistering moxibustion group and the antagonist group (P<0.05); AWR scores and EMG amplitude of abdominal muscles under 60, 80 mm Hg were all reduced in both the blistering moxibustion group and the antagonist group (P<0.05). Compared with the normal group, in the model group, the mucosa was slightly disturbed, while, the moderate inflammatory cells were visible in the submucosa. In comparison with the model group, the inherent glands of mucosa were regular in shape and a small number of inflammatory cells were visible in both the blistering moxibustion group and the antagonist group. In comparison with the normal group, the average positive staining area percentage (APSAP) of 5-HT and 5-HT3R of the colon tissue was increased, while, APSAP of 5-HT4R was reduced in the model group (P<0.05). Compared with the model group, APSAP of 5-HT and 5-HT3R was reduced in both the blistering moxibustion group and the antagonist group (P<0.05).@*CONCLUSION@#Blistering moxibustion can relieve the visceral hypersensitivity of the mice with visceral hypersensitive IBS and the underlying mechanism is related to the regulation of the gut-brain axis mediated by 5-HT signaling pathway.

Effect of calcium dobesilate in preventing contrast-induced nephropathy in patients with diabetes and chronic kidney disease

OBJECTIVES: This study assessed the protective effect of calcium dobesilate against contrast-induced nephropathy (CIN) after coronary angiography (CAG) or percutaneous coronary intervention (PCI) in patients with diabetes and chronic kidney disease (CKD). METHODS: A total of 130 patients with diabetes and CKD estimated glomerular filtration rate: 30-90 mL/min/1.73m2 were enrolled and included in the analysis. They were divided into experimental (n=65) and control groups (n=65). Patients in the experimental group were administered oral calcium dobesilate (500 mg) three times daily for 2 days before and 3 days after the procedure. The serum creatinine (SCr), cystatin C (Cys C), and neutrophil gelatinase-associated lipocalin (NGAL) levels were measured before and after the procedure. RESULTS: The mean SCr level at 24h after the procedure was found to be significantly lower in the experimental group than in the control group (79.1±19.6 μmol/L vs. 87.0±19.3 μmol/L, p=0.023). However, the Cys C and NGAL levels were not significantly different between the two groups at all measurement time points (all p>0.05). The incidence of CIN defined by the SCr level was significantly lower in the experimental group than in the control group (3 [4.6%] vs. 13 [20.0%], p=0.017). However, the incidence of CIN defined by the Cys C level was not statistically different between the two groups (7 [10.8%] vs. 7 [10.8%], p=1.000). CONCLUSIONS: This study revealed that calcium dobesilate has no preventive effect against CIN in patients with diabetes and CKD.

Molecular Mechanism of Modified Guizhi Fulingwan Intervention on Uterine Fibroids in Rats Based on micRNA Expression Profiling / 中国实验方剂学杂志

Objective:To explore the molecular mechanism of modified Guizhi Fulingwan in rats with uterine fibroids. Method:Seventy-two female adult SD rats of SPF grade were randomly divided into a model group， a normal group， and a preventive administration group. The model group and preventive administration group were established by estrogen and progestin loading method. After successful modeling， the rats in the model group were randomly divided into a western medicine group （mifepristone）， the high-dose traditional Chinese medicine（TCM） group， and a low-dose TCM group. All the rats were dosing as required once a day for 28 consecutive days. Hematoxylin-eosin（HE）staining was used to observe the morphological changes of the uterus. The micRNA gene chip was used to detect the expression profile of uterine micRNA gene. Differential expressions of micRNA were screened by bioinformatics methods. Gene function enrichment was used to predict the possible signaling pathways in rats with uterine fibroids by modified Guizhi Fulingwan. Result:Compared with the normal group， microRNA of the model group was 1 up-regulated and 9 down-regulated. Compared with the model group， microRNA of the high-dose group of TCM group was 2 up-regulated and 1 down-regulated， in the preventive administration group， 9 was up-regulated and 2 was down-regulated. Gene function enrichment analysis indicated that four signaling pathways were closely related to uterine fibroids. They were mitogen-activated protein kinase （MAPK） signaling pathway， Wnt signaling pathway， mammalian rapamycin target protein （mTOR） signaling pathway and vascular endothelial cell growth factor （VEGF） signaling pathway. Conclusion:Modified Guizhi Fulingwan affected the expression profile of micRNA in rat model of uterine fibroids induced by estrogen and progesterone， suggesting that modified Guizhi Fulingwan may involve in a variety of biological processes such as signal transduction and gene regulation in the treatment of uterine fibroids.

Correlation between DNA Methylation of ZNF772 Promoter Region and Cervical Cancer / 中国医学科学院学报

To investigate the DNA methylation in ZNF772 promoter region and its mRNA and protein expressions and analyze the clinical significance of DNA methylation of ZNF772 gene in cervical cancer. Cervical squamous cell carcinoma (SCC) tissues were harvested from three patients (SCC group),and normal cervical tissues from healthy individuals of the same age were used as the control group. Hyper-methylation and lower transcripts were screened by whole-genome bisulfite sequencing (WGBS) and RNA sequencing. Furthermore,in 40 cervical tissue samples in SCC group and 45 normal cervical tissues in the control group,DNA methylation status and mRNA expression of ZNF772 were measured by using real-time quantitative polymerase chain reaction (RT-qPCR) and bisulfite sequencing polymerase chain reaction (BSP). The protein expression was detected by immunohistochemistry. In the SCC group,the potential relationships of DNA methylation status in ZNF772 promoter and mRNA expression with the clinicopathological parameters of cervical cancer were analyzed. As shown by WGBS and RNA sequencing,the abnormal DNA methylated gene ZNF772 was associated with mRNA expression. RT-qPCR verified that the mRNA expression of ZNF772 was significantly lower in SCC group than in control group (=8.351,=0.016). Immunohistochemistry further confirmed that the positive expression of ZNF772 protein was down-regulated in SCC group (=3.802,=0.005). BSP showed that the DNA methylation rate of ZNF772 promoter region (-420,-422 locus) in SCC group was significantly higher than that in control group (=8.566,=0.038;=6.332,=0.043). Spearman correlation analysis showed that,in SCC group,DNA hypermethylation in ZNF772 promoter was negatively correlated with the mRNA expression (=-0.351,=0.045;=-0.349,=0.032) and was significantly correlated with HPV16/18 infection,tumor size,World Health Organization pathological grade,and International Federation of Gynecology and Obstetrics clinical stage (=0.018,=0.012,=0.009,and =0.035,respectively). The DNA hypermethylation in the promoter region of ZNF772 gene is involved in the occurrence and development of cervical cancer.

Objective To investigate the regulatory role of recombinant Trichinella spiralis cysteine protease inhibitors (rTs-Cys) in induction of polarization of bone marrow-derived macrophages (BMDMs) in vitro. Methods BMDMs were captured and cultured in conditioned medium for 7 days. Then, mature BMDMs were harvested and assigned into four groups. Cells in Group A (negative control) were given 10 ng/mL IFN-γ combined with 100 ng/mL LPS, cells in Group B (positive control) were treated with IL-4 and IL-10 (at 10 ng/mL both), and cells in Group C (recombinant protein alone) were stimulated with 1 μg/mL rTs-Cys, while cells in Group D (protein co-culture) were simultaneously treated with 1 μg/mL rTs-Cys, 10 ng/mL IFN-γ and 100 ng/mL LPS. Cells and culture supernatant were collected 24 hour post-treatment, and the proportions of F4/80+, CD11b+, CD206+ and CD11c+ cells were detected by flow cytometry. The levels of interleukin IL-6 (IL-6), tumor necrosis factor-α (TNF-α), IL-10 and transforming growth factor-β (TGF-β) in the cell culture supernatant were measured by ELISA and the CD86+ and CD206+ phenotypes were identified by immunofluorescent staining. Results Flow cytometry detected no significant difference in the proportion of F4/80+ CD11b+ CD11c+ cells among the four groups (F = 46.184, P < 0.001), and a lower proportion of F4/80+ CD11b+ CD11c+ cells was seen in groups C and D than in group A (all P values < 0.001). There was a significant difference in the proportion of F4/80+ CD11b+ CD206+ cells among the four groups (F = 11.032, P < 0.001), and a greater proportion of F4/80+ CD11b+ CD206+ cells was seen in groups C and D than in group A (all P values < 0.01). Immunofluorescent staining showed higher CD206+ expression and lower CD86+ expression in groups C and D than in Group A. There were significant differences in the IL-6 and (F = 3.950, P < 0.001) and TNF-α (F = 205.827, P < 0.001) levels in the cell culture supernatants among the four groups, and significantly lower IL-6 and TNF-α levels were measured in groups C and D than in Group A (both P < 0.05). There were significant differences in the IL-10 and (F = 8.274, P < 0.001) and TGF-β (F = 13.559, P < 0.01) levels in the cell culture supernatants among the four groups, and greater IL-10 and TGF-β levels were measured in Group C than in Group A (both P values < 0.01). In addition, the TGF-β level was significantly higher in Group D than in Group A (P < 0.05); however, there was no significant difference in the IL-10 level between groups D and A (P > 0.05). Conclusion rTs-Cys may induce the polarization of BMDMs to antiinflammatory M2 macrophages in vitro and inhibit the activation of M1 macrophages.

Objective To observe the effects of long-chain non-coding RNA XLOC009038 on the proliferation, apoptosis, migration and invasion of esophageal squamous cell carcinoma EC 109 and EC9706 cells and explore its mechanism. Methods XLOC009038 interfering plasmid was constructed and transfected into EC 109 and EC9706 cells to down-regulate the expression of XLOC009038 gene. MTT colorimetry and clonogenic assay were used to observe the changes of cell proliferation and cloning ability before and after gene down-regulation.Flow cytometry was used to detect apoptosis. Transwell was used to measure the changes of cell migration and invasion ability before and after transfection. Western blot was used to detect the expression of procaspase 3 protein in cells before and after transfection. Results The expression of XLOC009038 gene in the two cells was significantly lower than that in the control group (P < 0.001). After down-regulation of XLOC009038 gene expression, the cloning and proliferation ability of EC 109 and EC9706 cells decreased significantly (P< 0.05). Compared with the control group, the migration and invasion ability of EC 109 and EC9706 cells decreased significantly (P < 0.001).Flow cytometry showed that the apoptosis rate of EC 109 and EC9706 cells increased after down-regulation of XLOC009038 (P <0.001). The expression of procaspase 3 increased in the experimental group after interfering with XLOC009038 (P = 0.013; P < 0.001). Conclusions Over-expression of XLOC009038 might be closely related to occurrence and development of the esophageal cancer. Over-expression of XLOC009038 can enhance the proliferation, apoptosis, migration and invasion of esophageal cancer cells in vitro through the procaspase3 pathway.

Clinical Characteristics of Sleep Disorders in Patients with Parkinson's Disease / 华中科技大学学报（医学）（英德文版）

In order to investigate the sleep quality and influencing factors in patients with Parkinson's disease (PD),201 PD patients were enrolled and underwent extensive clinical evaluations.Subjective sleep evaluation was assessed using the Pittsburgh Sleep Quality Index (PSQI),and the Epworth Sleepiness Scale (ESS).It was found that poor sleep quality (77.11％) and excessive daytime sleepiness (32.34％) were commonly seen in PD patients and positively correlated with disease severity.Then 70 out of the 201 PD patients and 70 age-and sex-matched controls underwent a polysomnographic recording.The parameters were compared between PD group and control group and the influencing factors of sleep in PD patients were analyzed.The results showed that sleep efficiency (SE) was significantly decreased (P＜0.01),and sleep latency (SL) and the arousal index (AI) were increased (P＜0.05) in the PD group as compared with those in the control group.SE and total sleep time (TST) were positively correlated with the Hoehn and Yahr (H&Y) stage.There was significant difference in the extent of hypopnea and hypoxemia between the PD group and the control group (P＜0.05).Our results indicate that PD patients have an overall poor sleep quality and a high prevalence of sleep disorder,which may be correlated with the disease severity.Respiratory function and oxygen supply are also affected to a certain degree in PD patients.

Effects of Different Concentrations of 4 Traditional Chinese Medicine Injections on Insoluble Particles / 中国药师

Objective:To investigate the change of insoluble particles in 4 traditional Chinese medicine injections at different con-centrations in 0. 9% NaCl injection. Methods:Fufang Kushen injection, Shuxuetong injection, Lugua Duotai injection and Honghua Huangsesu injection were diluted by 0. 9% sodium chloride injection to obtain low concentration and high concentration solutions. The insoluble particles number of initial injections and dilutions at different time points(0,2,4,and 5 h) was detected according to the in-soluble particles test described in the fourth principle 0903 of China Pharmacopoeia (2015 edition). Results:The number of insoluble particles in 4 traditional Chinese medicine injections and 0. 9% sodium chloride injection met the requirements. The insoluble particles (≥25 μm) in 4 traditional Chinese medicine injections at different concentrations were few and almost stable with time, the insoluble particles(≥10 μm) showed an increasing trend in a concentration-dependent manner and varied with time. Conclusion:The insoluble particles(≥10 μm) in traditional Chinese medicine injections at high concentration are more than those at low concentration, which suggests that the concentration of traditional Chinese medicine injections should be restricted strictly according to the prescriptions and used up as soon as possible.

Effects of recent upper respiratory-tract infections on incidence of the perioperative respiratory adverse events in children: a prospective cohort study / 北京大学学报(医学版)

Objective:To investigate the effects of the recent upper respiratory tract infections (URI) on the incidence of perioperative respiratory adverse events in children scheduled to undergo general anesthesia and elective surgery.Methods:In the study,232 children undergoing general anesthesia with laryngeal mask airway (LMA) for elective ophthalmic surgeries at Peking University First Hospital,Beijing,China,from Nov.1,2015 to May 10,2016 were enrolled.On the day of the surgery,the parents of the children were preoperatively asked to fill out a questionnaire regarding the baseline characteristics and medical history of the children,including gender,age,height,weight,history of URI within the last 2 weeks before anesthesia,history of premature,long-term passive smoking exposure,habitual sleep snoring,and history of asthma.In addition,all adverse respiratory events throughout the perioperative periods (oxygen desaturation,cough,copious secretions,laryngospasm and bronchospasm) as well as perioperative variables (number of attempts to insert the LMA successfully,anesthesia duration and so on) were recorded.Multivariate Logistic regression analysis was applied to identify independent risk factors of perioperative respiratory adverse events.Results:Among the 232 children included in the study,28.0％ (65/232) presented with a history of a recent URI within the last 2 weeks before anesthesia.The presence of the recent URI increased the incidence of oxygen desaturation (23.1％ vs.12.0％,P =0.034),copious secretions (15.4％ vs.6.6％,P =0.036) and any of all the adverse respiratory events (32.3％ vs.18.6％,P =0.024).Multivariate Logistic regression analysis identified two independent risk factors of perioperative adverse respiratory events:a history of URI within the last 2 weeks before general anesthesia (OR =2.021,95％ CI:1.023-3.994,P =0.043) and habitual sleep snoring (OR =3.660,95％ CI:1.517-8.832,P =0.004).Conclusion:A history of a recent URI within 2 weeks before general anesthesia was associated with a higher incidence of oxygen desaturation,copious secretions and the overall respiratory adverse events.For the children with recent URI,we recommend the general anesthesia and elective surgery should be postponed for at least 2 weeks after the URI.

Association Between Dentin Matrix Protein 1 (rs10019009) Polymorphism and Ankylosing Spondylitis in a Chinese Han Population from Shandong Province / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Ankylosing spondylitis (AS) is the most common rheumatic condition that is slowly progressive and predominantly affects adolescents. Pathological bone formation associated with AS is an important cause of disability. The aim of the study was to investigate the possible involvement of the genes related to endochondral ossification and ectopia ossification in genetic susceptibility to AS in a Chinese Han population.</p><p><b>METHODS</b>Sixty-eight single nucleotide polymorphisms (SNPs) from 13 genes were genotyped in discovery cohorts including 300 AS patients and 180 healthy controls. The rs10019009 in dentin matrix protein 1 (DMP1) gene shown as association with AS after multiple testing corrections in discovery cohorts was replicated in a validation independent cohort of 620 AS patients and 683 healthy controls. The rs10019009 was assessed with bioinformatics including phylogenetic context, F-SNP and FastSNP functional predictions, secondary structure prediction, and molecular modeling. We performed a functional analysis of rs10019009 via reverse transcription-polymerase chain reaction, alkaline phosphatase (ALP) activity in human osteosarcoma U 2 OS cells.</p><p><b>RESULTS</b>Interestingly, the SNP rs10019009 was associated with AS in both the discovery cohort (P = 0.0012) and validation cohort (P = 0.0349), as well as overall (P = 0.0004) in genetic case-control association analysis. After a multivariate logistic regression analysis, the effect of this genetic variant was observed to be independent of linkage disequilibrium. Via bioinformatics analysis, it was found that the amino acid change of the rs10019009 led to changes of SNP function, secondary structure, tertiary conformation, and splice mode. Finally, functional analysis of rs10019009 in U 2 OS cells demonstrated that the risk T allele of the rs10019009 increased enzymatic activity of ALP, compared to that of the nonrisk allele (P = 0.0080).</p><p><b>CONCLUSIONS</b>These results suggested that the DMP1 gene seems to be involved in genetic predisposition to AS, which may contribute to the ectopic mineralization or ossification in AS. In addition, DMP1 gene may be a promising intervention target for AS in the future.</p>
