Objective To investigate the NAT(nucleic acid amplification technique)-HBV/HCV results among single ALT(+)blood donors,in order to provide theoretical basis of optimizing strategy for blood screening.Methods A total of 28 800 samples,from December 2006 to December 2007,were studied retrospectively.ALT was tested by rate method.HBV-DNA and HCV-RNA in single ALT(+) samples were detected via NAT-HBV/HCV.The relationship between positive ALT values and ELSIA-HBV/HCV OD values was analyzed.Results A total of 2 516 ALT(+) cases were found in 28 800 samples.Of these ALT(+)cases,8 positive cases were found via NAT-HBV/HCV,including 5 HBV-DNA(+) and 3 HCV-RNA(+) cases.The positive rates of NAT-HBV/HCV for the donors with ALT values ≤80 U/L were significant lower than those with ALT values≥81 U/L(P

OBJECTIVE To analyze the correlation between number of tissue eosinophils(Eos) and blood Eos levels in patients with chronic rhinosinusitis with nasal polyps(CRSwNP), and to investigate if tissue and blood eosinophilia predicts disease severity and prognosis in CRSwNP. METHODS A retrospective analysis of 102 patients, who diagnosed with CRSwNP was carried out in this study. Surgical specimens were evaluated for degree of tissue Eos, which was compared with blood Eos. Patients were divided into two groups according to the results of endoscopy one year after surgery: recurrent and non-recurrent group. Statistical analysis was performed to compare tissue and blood Eos and CT Lund-Mackay scores. RESULTS Blood and tissue Eos in recurrent group was significantly higher than that in non-recurrent group(P=0.032, 0.033, 0.017). There was not a statistical difference of CT scores between two groups(P =0.089). There was a significant correlation between tissue Eos and absolute number of blood Eos(r=0.637, P=0.000) as well as between tissue Eos and percentage of blood Eos(r=0.542, P=0.000). However Eos and CT scores were not correlated statistically(P>0.05). CONCLUSION Blood Eos levels can predict the degree of Eos infiltration in nasal polyps. Blood and tissue Eos correlate with prognosis.

Objective To identify the differences inneuropsychological characteristics between amnestic(AMCI)and vascular mild cognitive impairment(VMCI).Methods Totally 297 old community residents with mild cognitive impairment(MCI)were divided into amnestic MCI(AMCI)and vascular MCI(VMCI)subgroup from Guangzhou MCI prevalence survey.The elderly with MCI were interviewed and tested with the Chinese version of Montreal Cognitive Assessment(MoCA),the Mini-Mental state examination(MMSE),Auditory Verbal Learning Test(AVLT),the Clinical Dementia Rating scale(CDR),Functional Activity Questionnaire(FAQ),the Modified Hachinski Ischemic Scale(M-HIS),Center for Epidemiologic Studies(CES-DC)to evaluate neuropsychological characteristics.Results AMCI versus VMCI group showed that the total scores of MoCA were(9.63±5.17 vs.9.98±6.02),total scores of MMSE were(16.90±4.84 vs.16.90±6.19),AVLT immediate memory was(2.35±1.39 vs.2.91±1.84),AVLT delayed recall was(2.23±2.09 vs.2.47±2.20),AVLT delayed recognition was(7.33±3.98 vs.6.85±4.02)and total scores of CDR(0.5 vs.0.5),with no differences between the 2 groups(all P>0.05).Based on MoCA survey,AMCI versus VMCI group showed statistically significant differences(all P<0.05)in parameters of visual space and execution(0.71±1.02 vs.0.92±1.26),language function(0.34±0.56 vs.0.50±0.80)and abstract thinking(0.25±0.49 vs.0.15±0.43),but based on MMSE survey,no difference was found in the various cognitive domains between the two groups.The AMCI versus VMCI group showed statistically significant differences(all P<0.05)in parameters of CES-DC scale(1.75±4.27 vs.2.76±6.72),FAQ scale(4.42±4.66 vs.8.71±7.03),M-HIS scale(0.40±0.64 vs.7.59±3.53).Conclusions There is no significant difference in general cognitive impairment between AMCI and VMCI,but the visual space and execution,language function are more impaired in AMCI than VMCI,and the abstract thinking,social function are more impaired with more depressive symptoms in VMCI than in AMCI.

Objective: To investigate the clinical effect of one-stage revision combined with intra-articular injection of antifungal agents in the treatment of chronic periprosthetic fungal infection. Methods: A retrospective analysis of 11 patients(4 hips, 7 knees) admitted with chronic periprosthetic fungal infection at Department of Orthopaedics, First Affiliated Hospital of Xinjiang Medical University from January 2004 to April 2016.There were males and females with an age of 67 years (range:47-77 years). Each patient underwent single-stage revision including aggressive soft-tissue debridement. Liquid samples and tissue samples were immediately sent to the microbiology laboratory for drug sensitivity testing and histological analysis. Removed the infected components and cement thoroughly, pouring powdered vancomycin into the medullary cavity and direct intra-articular injection of fungussensitive antibiotics. The patients with infected hips received an uncemented prosthesis and 0.5 g of gentamicin loaded commercial cement was received by the patients with infected knee.After that, a new prosthesis was implanted.Long-term combination therapy of antibacterial agents and antifungal agents were given after operation. Recurrence of infection and clinical outcomes were evaluated. The follow-up period was 5 years (range: 2-12 years). Results: One patient died of acute heart failure on the eighth postoperative day.Three infection cases were recurred.Eight cases had satisfactory outcomes and required no additional surgical or medical treatment for recurrence of infection. The Harris hip score assessed preoperatively and at latest follow-up was increased from 39.25±5.12 to 79.50±4.79, the difference was statistically significant (t=-11.356, P=0.001).The Hospital for Special Surgery knee score was improved from preoperative 46.25±5.61 to final follow-up 80.50±5.06, and the difference was statistically significant (t=-9.930, P=0.002). Conclusion Treatment of chronic fungal periprosthetic joint infection with single-stage revision can be fairly effective for achieving acceptable functional outcomes.

Objective To investigate the difference in behavioral and psychological symptoms among Al-zheimer's disease(AD)patients with different severity of white matter hyperintensity(WMH). Methods A total of 37 AD patients were enrolled and were followed-up for 4 weeks. They were checked by 3.0 T MRI at baseline, including T1,T2-weighted phase and fluid-attenuated inversion recovery sequence(FLAIR phase).The image pro-fessionals analyzed the images and process data.The Fazekas scale was used for WMH rating.Assessment tools in-cluded the Neuropsychiatric Inventory(NPI)、MMSE and ADAS-cog. Results There were 14 patients in none-mild WMH group and 23 patients in moderate-severe WMH group. The age of two groups were 71.3 ± 12.5 and 78.7 ± 6.1 years old respectively(P<0.05).The comparison of NPI,MMSE and ADAS-cog assessment results be-tween two groups show that there is significance difference in NPI baseline scoring and 4-week scoring.The score in moderate-severe group w is higher than that in the none-mild group(P < 0.05). However,the changed value of baseline-4-week NPI is not statistically significant. There is no significant difference between MMSE and ADAS -cog score and changed value.Conclusion Taken together,the severity of WMH may be related to behavioral and psychological symptoms of patients with Alzheimer's disease.
