RESUMO
Post traumatic depression (PTD) is a serious complication after traumatic brain injury, with high incidence rate; PTD seriously affects the rehabilitation, outcome and quality of life of patients. Due to unclear pathogenesis of PTD, effective treatments have not yet been found in clinical practice. Repetitive transcranial magnetic stimulation (rTMS), as a new non-invasive neuroregulatory technique, has been used in major depression disorder (MDD). Few clinical evidence on PTD treated by rTMS is noted and optimal rTMS treatment regimen has not yet been defined.This article reviews the clinical studies of rTMS in PTD in recent years, with a view to provide references for clinical application.
RESUMO
Objective To detect the levels of carotid intima-media thickness(CAIMT),serum homocysteine(HCY),malondialdehyde(MDA) and superoxide dismutase(SOD) activity,in order to investigate the correlation between carotid atherosclerosis(CAS) and serum HCY and oxidative stress in essential hypertension(EH) patients.Methods 50 patients with EH and 266 healthy controls were enrolled in this study.The color Doppler ultrasonography was used to detect CAIMT,and circulating enzyme method was used to detect serum HCY,and MDA levels were detected by TBA and SOD activity was detected by colorimetric assay of and the results of the examination were statistically analyzed.Results The incidence rate of CAS in EH patients was 62.8%(167/266),associated with age,disease and related course,and there was no significant difference in gender.In EH concurrent CAS group,the serum HCY level,MDA level and SOD activity were (28.06±6.94)μmol/L,(13.10±2.75)μmol/L and (69.73±6.51)U/mL,respectively,which of the control group were (11.74±3.62)μmol/L,(4.71±1.18)μmol/L and (136.07±10.16)U/mL,respectively,the levels of serum HCY and MDA in EH complicated CAS group were significantly higher than those in the control group(t=7.118,6.326,all P<0.05),and the activity of SOD was significantly decreased.The serum HCY level was positively correlated with MDA level(r=0.493,t=9.207,P<0.05),and negatively correlated with serum SOD activity(r=-0.562,t=11.040,P<0.05).Conclusion EH patients have high levels of HCY,MDA and SOD activity of low levels.HCY level is significantly increased and oxidative stress is increased in CAS patients.Oxidative stress is associated with serum HCY level.
RESUMO
Objective To provide evidences which are for clinicians to formulate effective prevention and treatment measures by analyzing the perinatal pregnant women vaginal group B streptococcus (GBS)infection and adverse pregnancy outcomes. Methods From January 2013 to February 2015,the vaginal secretions were sampled from 795 cases of perinatal pregnant women for culture identification of GBS,the final results were statistical analyzed.Results In the 795 pregnant women ca-ses,there were 256 GBS carriers cases,the carrier rate was 32.2%.There was statistically significance (χ2 = 19.095,P <0.01)between less than 30 years old group (28.9%)and greater than or equal to 30 years old group (42.3%).The differ-ent incidence rate of clinical symptoms between GBS negative cases and GBS positive cases (18.8% vs 8.0%)was also had statistically significance (χ2 =39.514,P <0.01).The antimicrobial resistant rates of ten kinds of antibacterial drugs (vanco-mycin,linezolid,penicillin,ampicillin,ceftriaxone,nitrofurantoin,levofloxacin,clindamycin,erythromycin and tetracycline) was 0,0,0.6%,3.1%,6.6%,9.6%,21.9%,23.8%,29.9% and 58.1% respectively.The positive rate of D-bacteriostatic ring experiment was 23.9%.Conclusion The carrier rate of perinatal pregnant women GBS was higher in this region,and the elderly were easier to be infected.Perinatal pregnant women infected with GBS to vancomycin and rina thiazole amine and penicillin and ampicillin and ceftriaxone and with nitrofurantoin because of the sensitive rate is high.

RESUMO
Objective To explore the method of rapid diagnosis preterm premature rupture of membrane (PPROM)and prognosis factors of residual amniotic fluid in mother and infant through monitoring nonphosphorylated insulin -like growth factor binding protein -1 (IGFBP -1)and the residual amniotic fluid index (AFI)of the cervi-covaginal secretions from PPROM women.Methods 96 cases of PPROM were tested IGFBP -1 of cervicovaginal secretions,AFI were tested by abdominal ultrasound through fast chromatography methods,and the cause was ana-lyzed.The pregnancy outcome and neonatal prognosis were compared.Results 92 cases positive of IGFBP -1 were diagnosed with PPROM.The risk factors of PPROMwere mainly reproductive tract infections,abortion,induced labor history and unknown causes (including no evidence of infection,fetal membrane dysplasia unclear or other factors), the twins,multiplets,macrosomia,breech or cephalopelvic disproportion,gestational hypertension disease,uterine fibroids or deformity,malnutrition and polyhydramnios.In the 92 patients with PPROM pregnant women,the duration from premature rupture of membrane to delivery was (105.7 ±13.9)h,cesarean section rate was 51.1%,fever rate of pregnant women was 7.6%,the rate of placental abruption was 4.3%,the rate of fetal distress was14.1%,perinatal infection rate was 21.7%,and neonatal asphyxia rate was 7.6%,the neonatal mortality was 7.6%.To compare the AFI≤40mm group with AFI >40 mm group,the duration from premature rupture of membrane to delivery was short-ened remarkably (t =10.904,P <0.05),the neonatal mortality rate was significantly increased (χ2 =4.359,P <0.05).Conclusion Measurement of IGFBP -1 and AFI in cervicovaginal secretions can rapid diagnosis PPROMand evaluate the results of pregnancy and neonatal prognosis,and can guide clinical improvement of pregnancy safety and reduce neonatal mortality.
RESUMO
Objective To study the correlation of carotid artery atherosclerosis (CAS) and helicobacter pylori (Hp) infection in patients with essential hypertension (EH) by observing the carotid intima-media thickness (CAIMT),helicobacter pylori (Hp)-IgG antibody,blood lipid,high sensitive C-reactive protein (hs-CRP),and homocysteine(HCY).Methods To measure CAIMT,blood lipid,serum Hp-IgG antibody,hs-CRP,and HCY were measured by color doppler ultrasound instrument,and Hp-IgG antibody by colloidal gold method.Results A total of 150 EH patients were randomly divided into CAIMT and Hp-IgG-antibody groups,and were taken statistical analysis.Results There were 89 patients with EH CAIMT > 1.0 mm(59.3%) as the intimal thickening,and 67 cases of Hp-IgG antibody(+) (44.7%) for Hp infection.CAIMT thickening (73.1%) in the Hp infection group was significantly higher than that of Hp infection group (48.2%) (P <0.05).In the thickened CAIMT group,Hp infection (55.1%) was significantly higher than that of CAIMT non thickening (29.5%) (P <0.05).EH patients complicated with CAIMT thickening and Hp infection had significant correlation (r =0.179,t =2.213,P <0.05).In the Hp infection group,the levels of serum triglyceride (TG),total cholesterol(TC),low density lipoprotein cholesterol (LDL-C),HCY,and hs-CRP were significantly higher than those of Hp infection group (P < 0.05).Serum high density lipoprotein cholesterol (HDL-C) were significantly lower than those of the Hp infection group (P < 0.05).Conclusions The study proved the correlation of CAS and Hp infection in patients with EH,and promoted the development of CAS probably by influencing the blood lipid metabolism,inflammatory reaction and HCY levels.It would be one of the treatment of EH with CAS by removing or prevention of Hp infection.
RESUMO
Objective To observe the effects of intensive insulin therapy on IL-10 level and NF-ΚB activity in peripheral blood mononuclear cells in patients undergoing cardiopulmonary bypass.Methods The non-diabetic patients undergoing cardiopulmonary bypass in our department were selected and assigned to intensive therapy group (group A,n=40) and received strict glycemic control after the initiation of surgery.And those who undergoing cardiac surgery but without strict glycemic control were assigned to routine therapy group (group B,n=40) as controls.The blood glucose in group A was maintained at 4.4~8.3mmol/L,whereas the glucose in group B was below 11.lmmol/L.The concentration of serum IL-10 and NF-ΚB activity in peripheral blood mononuclear cells was measured at different time points.Results There were no significant differences in general data between two groups.The concentration of IL-10 in group B was significantly lower than that in group A(P<0.05).compared with group B,strict glycemic control markedly suppressed NF-KB activation (P<0.05).Conclusion Intensive insulin therapy could reduce the activity of NF-ΚB and then reduce the expression of IL-10.Strict glycemic control could significantly mitigate the systemic inflammatory response.
