Objective To evaluate the targeted antimicrobial prophylaxis in men undergoing trans-rectal ultrasound guided prostate biopsy based on rectal swab culture results.Methods From July 2008 to April 2012 we studied differences in infectious complications in men who received targeted vs standard empirical ciprofloxacin prophylaxis before transrectal ultrasound guided prostate biopsy.All 344 patients were divided into 3 groups according to their hospital records,inculding group A:without antimicrobial prophylaxis(105 eases) ;group B:antimicrobial prophylaxis with fluoroquinolone(117 cases) ;group C:targeted prophylaxis used rectal swab cultures results(122eases).All cases received enema with diluted iodophors before biopsy.We identified men with infectious complications within 7 days after transrectal ultrasound guided prostate biopsy using the electronic medical record,following 3 conditions.Results In group A of 105 case,17 cases of fever were recorded,including prostatic abscess of 3 cases and septicemia of 1 case.Three cases of fever were occurred in group B,including 1 case of bacteremia and 1 case of prostatitis.No infectious complications were recorded in group C.Conclusions Targeted antimicrobial prophylaxis was associated with a notable decrease in the incidence of infections complications after transrectal ultrasound guided prostate biopsy,although fiuoroquinolone can provide good protective effets.

Objective:To investigate the clinical characteristics of renal injury caused by Guanxinsuhe pill(冠心苏合丸,including slander dutchanspipe root(青木香)).Methods:The clinical data of 27 patients with renal injury caused by Guanxinsuhe pill were studied.The clinical characteristics of the renal damage caused by Guanxinsuhe pill and the relationships between duration of illness,duration of taking Guanxinsuhe pill,anemia,renal atrophy and the progression of renal injury respectively were also analyzed.Results:Twenty-seven patients all taken Guanxinsuhe pill for suspicious coronary heart disease(CHD) and were diagnosed as chronic tubulointerstitial nephropathy accompanied with renal tubular acidosis,renal glucosuria and hyposthenuria after admission.Anemia was of more severity than renal dysfunction.Atrophic kidney occurred in 26 patients.The main complains were nonspecific symptoms including fatigue,anorexia,nausea,vomiting,etc.and accompanied with different degrees of chronic renal dysfunction.Twentyfour hours urinary protein excretions were 120-900 mg((490?250) mg).There were few red and white cells in uroscopy.Sixteen patients discontinuously took the Guanxinsuhe pill(one capsule,2-3 times a day) according to the pharmacopoeia for a long period.Ten patients took a dosage(two capsules,2-3 times a day) higher than that limited by the pharmacopoeia.Twenty-six patients took Guanxinsuhe pill discontinuously.One patient continuously took Guanxinsuhe pill until got renal dysfunction.The duration of taking Guanxinsuhe pill was 1-120 months(37.38?31.58),and the amount of 50-43 800 pills(4 576.00?8 830.54) were used,but the amount of pills of 3 cases was uncertain.The renal injury occurred within 30-216 months(95.41?56.74) after initiation of the drug taken.The renal injury obviously correlated with the anemia and the duration of taking Guanxinsuhe pill.Conclusion:Taking Guanxinsuhe pill can cause renal injury.The Guanxinsuhe pill dose indicated in pharmacopoeia also causes renal damage.The onset of renal injury is insidious.Most of the patients have the history of CHD and when the chronic nephropathy in most of such patients is detected,it is advanced to stage 5.The renal injury induced by Guanxinsuhe pill usually presents as chronic tubulointerstitial nephropathy,renal tubular dysfunction and anemia.Anemia is of more severity than renal dysfunction.The 24 hours urinary protein excretions of all the patients are lower than 1 000 mg daily.It is suggested to avoid taking Guanxinsuhe pill,adjust the prescription of Guanxinsuhe pill and do not use slander dutchanspipe root as an ingredient.

AIM:To further elaborate the effect of glucocorticoid receptor(GR) decrease on level of inflammatory media in rats after critical scald.METHOD:The changes of phospholipase A 2(PLA 2) activity and concentrations of tumor necrosis factor alpha (TNF?) and malondialdehyde (MDA), the product of lipid peroxidation metabolism in plasma and tissue homogenate have been studied in scalded rats with or without GR blockade by RU38486.RESULTS:The PLA 2 activity and the concentrations of TNF? and MDA in plasma and homogenate of pulmonary and renal tissue in scalded rats were significantly higher than those in the controls( P

Objective:To explore the expressions of miRNAs related to accelerating senescence in serum of the patients with amnestic mild cognitive impairment (aMCI), and to clarify their effects in the pathogenesis of aMIC.Methods:The levels of miRNAs related to accelerating senescence (miR-132, miR-193b, miR-130b, miR-20a, miR-296, miR-329 and miR-206) were measured in the serum of the patients with aMCI (aMCI group,n=66) and healthy controls(control group,n=76) using quantitative real-time PCR(qRT-PCR).The genes targeted by the altered miRNAs were predicted by TargetScan 6.0.DAVID was used to analyze the function of miRNA target genes.The serum levels of brain derived neurotrophic factor (BDNF) and silent in formation regulator 1(SIRT1) were measured by enzyme-linked immunosorbent assay (ELISA) method.Results:The expression levels of miR-206 and miR-132 in serum of the patients in aMCI group were significantly higher than those in control group (P<0.05).BDNF and SIRT1 were both target genes of miR-206 and miR-132.The levels of BDNF (29.50 μg·L-1± 3.13 μg·L-1) and SIRT1 (1.86 μg·L-1± 0.25 μg·L-1) in serum of the patients in aMCI group were both obviously lower than those in control group (BDNF: 32.29 μg·L-1±3.66 μg·L-1;SIRT1: 2.10 μg·L-1± 0.29 μg·L-1, P<0.05).Conclusion:The expression levels of miR-206 and miR-132 in serum of the aMCI patients are significantly up-regulated.Both of them might be involved in the pathogenesis of aMCI through inhibiting the BDNF and SIRT1 expressions.

Objective To investigate the prevalence of the depression and the activities of daily living in the elderly population in Hebei province.Methods In this cross-sectional study,3 176 subjects aged over 60 were selected from 4 urban communities in Hebei Province.The demographic data was collected,and the Center for Epidemiological Survey,Depression Scale,(CES-D) and the activities of daily living Scale (ADL) were used to assess their depression status and activities of daily living.Results Among the 3 176 subjects,268 cases (8.4％) got the CES-D scores of over 15 and 232 cases (7.3％) got the ADL scores of over 26.14.2％ of depression group needed life care,27.9％ of depression group had absence of daily living activities.Multivariate logistic results showed that gender (OR=2.142),diseases situation (OR=2.214),marriage (OR=0.484),and life abilities like shower (OR =1.333),walk around home (OR=1.275),wear clothes(OR=2.129),moving on a wheelchair(OR=1.118) had significant effect on depression.Conclusion Elder people population who have characteristics like female,single,illness,can't take shower by themselves,life care depended,more likely get higher CES-D scores and depression.

Objective To investigate the effect of Tangshan earthquake stress on the executive and memory func?tion in adults. Methods The objects were recruited from Tangshan Kailuan Mining Group. The exposed group included 251 subjects whose mothers exposed to the Tangshan earthquake during pregnancy in 1976. The control group included 341 subjects whose mothers was pregnant the year after the Tangshan earthquake. According to mother's pregnancy time relative to the earthquake exposed group was divided into 3 subgroups:the late pregnancy of earthquake exposed group, the second trimester of earthquake exposed group and the early pregnancy of earthquake exposed group. Wisconsin Card Sorting Test (WCST) was used to evaluate executive function, Brief Visuospatial Memory Test-Revised (BVMT-R) was used to evaluate memory function. Results The index of WCST were not different between two groups (P>0.05). Com?pared with control group, BVMT-R total scores were lower in earthquake exposed group [(25.54 ± 7.45) vs. (27.28 ± 7.10), P<0.01]. In the earthquake exposed group, pregnancy and sex had interaction effect on the nonpreservative errors (nRpe) of WCST (P<0.05). In the late pregnancy earthquake exposed group, male had higher nRpe than female (P<0.01). Preg?nancy time had main effect on offsprings' BVMT-R scores (P<0.05). The BVMT-R total scores were lower in late trimes?ter pregnancy and in second trimester pregnancy than in the early pregnancy (P<0.05). Conclusion The Tangshan earth?quake has potential effect on the memory function of the offsprings. The second trimester (4-to 6-month) and the third trimester (7-to 9-month) may be the sensitive pregnancy window of the stress during the pregnancy. The male offspring from late pregnancy of exposed earthquake have poorer executive function than female.

Objective:To explore the association between polymorphism of Histone Deacetylase 2 (HDAC2) gene and alcohol use disorder (AUD) in male people of Han nationality for seeking suitable single nucleotide loci(SNP), and provide reference for early diagnosis and intervention of alcohol use disorder(AUD).Methods:A total of 194 male AUD patients of Han nationality (case group) and 310 normal men of Han nationality (control group) were selected for the study. The genomic DNA of peripheral blood of the subjects in the two groups was extracted, and 13 SNP loci of HDAC2 gene were obtained from HapMap database. The subjects in the two groups were genotyped by Agena MassARRAY SNP genotyping method.SPSS 25.0 was used to statistically analyze the differences of genotype frequency and allele frequency between the two groups, and Haploview 4.2 software was used for linkage disequilibrium and haploid analysis. The multiple test correction was carried out by the replacement test with 50 000 replacement times.Results:The genotype frequency of the 3 SNP loci(rs9481408, rs6568819, rs9488289) of HDAC2 gene were statistically significant different between the case group and the control group (all P<0.05). Further analysis found that the three loci were significantly correlated with AUD in the recessive genetic model between case group and control group(T/T vs C/C-C/T: OR=1.78, 95% CI: 1.05-3.03, P=0.033; T/T vs C/C-C/T: OR=1.79, 95% CI: 1.05-3.03, P=0.032; G/G vs C/C-C/G: OR=1.85, 95% CI: 1.09-3.13, P=0.022). Seven SNP haplotypes were constructed and the association odds ratio of GATCTGCAATAA between the case group and control group was 2.44, and the difference was statistically significant ( P<0.05). Conclusion:The SNP loci rs9481408, rs6568819, rs9488289 in the HDAC2 gene and haplotype GATCTGCCAATAA are associate with AUD in male people of Han nationality. These results indicated that the HDAC2 gene is one of the susceptibility genes of AUD.

Objective:To explore the relationship between marital status and mild cognitive impairment in older adults.Methods:This study is a cluster random sampling.From January to December 2020, a questionnaire survey was conducted among older adults aged 60 years and over in four cities of Hebei Province.Finally, 2690 older adults with mild cognitive impairment and normal cognitive function were enrolled.The older adults were divided into 2 groups according to their marital status: married and living with their spouses(group E1), divorced or living alone(group E2). The mini-mental state examination(MMSE)scores of older adults in the two groups were compared.Moreover, the cognitive differences of older adults between the two groups and the interaction of marital status, social activities and life events on cognitive outcomes were analyzed.Results:The married older adults with partners had better cognitive preservation( P<0.01). The more life events were more likely to cause cognitive impairment( P<0.01), and the interaction of marital status, social activities and life events had a significant impact on cognition( P<0.01). Older men who were married and lived with spouse had better cognition than older women who were married and lived with spouse( P<0.05 in Model 3). The cognition of widowed elderly women was better than those of widowed elderly men( P<0.1 in Model 1; P<0.1 in Model 2). Among elderly men, the cognition of those married and living with spouse was better than that those of widowed( P<0.01 in models 1 and 2, P<0.1 in model 3). Among elderly women, those married and living with spouse had better cognitive outcomes than those widowed( P<0.01 in Model 1, P<0.01 in Model 2). Conclusions:Marital companionship is a protective factor for the cognition of older adults, and there are gender differences in the impact of marital status on cognition in late life.

ObjectiveTo observe the effect of brain-computer interface (BCI) training based on motor imagery on hand function in hemiplegic patients with subacute stroke. MethodsFrom June, 2020 to December, 2021, 40 patients with hemiplegia in subacute stroke from Department of Rehabilitation Medicine, Fifth Affiliated Hospital of Zhengzhou University were divided into control group (n = 20) and experimental group (n = 20) using random number table. Both groups accepted medication and routine comprehensive rehabilitation, while the control group accepted hand rehabilitation robot training, and the experimental group accepted the robot training using motor imagery-based BCI, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index, modified Ashworth scale, and measured integrated electromyogram of the superficial finger flexors, finger extensors and short thumb extensors of the affected forearm during maximum isometric voluntary contraction with surface electromyography. ResultsTwo patients in the control group and one in the experimental group dropped off. All the indexes improved in both groups after treatment (t > 2.322, Z > 2.631, P < 0.05), and they were better in the experimental group than in the control group (t > 2.227, Z > 2.078, P < 0.05), except the FMA-UE score of wrist. ConclusionMotor imagery-based BCI training is more effective on hand function and activities of daily living in hemiplegic patients with subacute stroke.

ObjectiveTo conduct a visualized analysis of the research related to the use of brain-computer interface technology for stroke rehabilitation in the past ten years, and identify and predict the hot spots and hot trends in order to promote the further development of this field. MethodsThe Web of Science Core Collection database was searched for literature related to brain-computer interface technology for stroke rehabilitation from January, 2011 to October, 2022. CiteSpace 5.8.R3 was used to analyze the number of publications, countries, institutions, authors, keywords, co-citations, and grant support. Results and ConclusionA total of 592 papers were included, and the annual number of publications in this field of research showed a rapid growth trend, and the research enthusiasm continued to increase. The United States was in the leading position in this field, with the highest number of cooperative publications and the highest intermediary centrality; China had certain advantages in this field, but still needed to strengthen the exchange and cooperation with other countries/regions. Foreign institutions and authors had formed a network of close cooperative relationships, and formed a high-impact team represented by Niels Birbaumer, Cuntai Guan, Kai Keng Ang, etc.; there were poor cooperative relationships among domestic authors and institutions, and there were geographical restrictions and lack of high-impact academic groups. The keywords "motor imagery" and "recovery" formed ten major clusters and 15 prominent words with high variation rates, showing a trend of diversification in research directions. The study of the efficacy of upper limb motor rehabilitation and central mechanisms has been the hot topics in this field and will continue for some time in the future; the use of lower limb brain-computer interface systems for improving foot drop, gait and balance in stroke patients and the application of multimodal brain-computer interfaces will probably become a hot topic in the future. Finally, the use of brain-computer interface-guided neurofeedback training for cognitive and language rehabilitation in stroke also needs attention.
