This study aimed to investigate viral infections and the prevalence of influenza-like illness (ILI) in Shijiazhuang, China, in 2011 and to provide a scientific basis for the diagnosis and control of respiratory tract infections. Throat swab specimens were collected from 483 cases of ILI who were outpatients in the influenza surveillance sentinel hospitals in Shijiazhuang between January and December 2011. All specimens were examined by multiplex RT-PCR for the following 15 respiratory tract viruses: adenovirus (ADV), human rhinovirus (HRV), human parainfluenza virus (PIV types 1-4), influenza virus A (FluA), influenza virus B (FluB), human enterovirus (HEV), respiratory syncytial virus (RSV-A and -B), human metapneumovirus (HMPV), human coronavirus (HCoV-229E/NL63 and -OC43/HKU1), and human bocavirus (HBoV). Among the 483 cases of ILI, 214 (44.31%) were positive for viruses, including ADV (8.7%), HEV (8.7%), RSV-A (8.07%), HRV (7.45%), FluA (5.38%), HCoV-OC43/ HKU1 (2.9%), PIV-3 (2.9%), HMPV (1.86%), PIV-1 (1.24%), HCoV-229E/NL63 (1.04%), PIV-2 (1.04%), HBoV (0.83%), and FluB (0.41%). Twenty-six (5.38%) of all cases were co-infected with two or more viruses, most commonly HEV/HRV with other viruses. Cases of viral infection were detected throughout the year, with peaks in January and February. ADV and HRV were detected throughout almost the whole year without obvious seasonality. HEV was detected between April and November, with a peak of prevalence in summer and autumn. FluA and FluB reached epidemic levels mainly in winter and spring. All cases of RSV were identified to be subtype A. PIV infection was mainly caused by PIV-3. The positive rate of HCoV-OC43/HKU1 infection was significantly higher than that of HCoV-229E/NL63. The leading five viruses that resulted in ILI Shijiazhuang in 2011 were HEV, ADV, RSV-A, HRV, and FluA, and these viruses have different epidemiological features.

Objective To evaluate the image quality of 64-multi detector computed tomography (MDCT)and the clinical accuracy in detecting coronary artery lesions.Methods One hundred and five patients were studied by MDCT.The results were compared with invasive coronary angiography(ICA). Patients were excluded for atrial fibrillation,but not for high heart rate,coronary calcification,or obesity. MDCT was analyzed with regard to image quality and presence of coronary artery lesions.Results The data evaluation of the image quality was based on a total of 1365 segments(13 coronary segments for each patient),of which 1144 segments were considered to have diagnostic image quality,but 221 segments (16.2%)could not be sufficiently evaluated because of severe calcifications(153 segments)and motion artifacts(68 segments).The median calcium score[Agatston score equivalent(ASE)]was 154(range 0—1983).87 of the 105 patients had an ASE of less than 1,000[median 105(range 0—994)],and 18 patients had an ASE greater than 1000[median 1477(range 1115—1983)].For detecting lesions with 50% or greater narrowing(without any exclusion criteria),the overall sensitivity,specificity,positive predictive value,and negative predictive value were 85.7%,97.9%,93.0%,and 95.5%,respectively. When limiting the number of patients to those with a calcium score of less than 1000 ASE,the threshold- corrected sensitivity for lesions with 50% or greater narrowing was 96.0%;specificity,98.9%;positive predictive value,95.3%;and negative predictive value,99.0%.Conclusion Our results indicate high quantitative and qualitative diagnostic accuracy of 64-slice MSCT in comparison to QCA in a broad spectrum of patients.

Objective To probe the value of 3.0T MRI in the preoperative assessment of rectal carcinoma.Methods The study recruited 41 patients who were confirmed by biopsy of rectal carcinoma and underwent conventional MRI, high-resolution MRI and diffusion weighted imaging(DWI), the distance from the inferior part of tumor to transitional skin and the percentage of circumferential invasion were measured, the tumor's T staging, N staging,and the status of circumferential resection margin(CRM) and extramural vascular invasion(EMVI) were assessed.MRI findings were compared with endoscope and postoperative pathological results.Results MRI could accurately show the distance from the inferior part of tumor to transitional skin(P>0.05);The mean percentage of circumferential invasion for the tumor with T1-T2 and T3 were 61%,83% respectively (P>0.05);The total accuracy of T,N staging diagnose were 80.5%,75.6% respectively, which had a better consistent with pathological T,N staging(Kappa=0.564,0.634);The total accuracy of CRM and EMVI diagnose were 90.2%,73.2% respectively,which had a better or moderate consistent with pathological diagnose(Kappa=0.765,0.461).Conclusion 3.0T MRI has the unique application in the preoperative assessment of rectal carcinoma, which can provide more comprehensive information for clinic.

Acupuncture and moxibustion for treatment of neurogenic bladder dysfunction after spinal cord injuries at home and abroad in recent years is introduced. The acupuncture and moxibustion methods for treatment of this kind of disease are classified and analyzed from body acupuncture, electroacupuncture, acupoint pressure and massage, acupoint-injection, acupoint sticking and so on. Acupuncture and moxibustion are widely applied to treatment of neurogenic bladder dysfunction after spinal cord injuries, with definite therapeutic effect and good safety. The effectiveness of other evaluation indexes of acupuncture and moxibustion for treatment of neurogenic bladder dysfunction after spinal cord injuries needs to be proved by more randomized and controlled trials of high quality with strict design and scientific methods.

Objective : To investigate the willingness to receive HIV testing in primary health service institutions (PHSIs) among young students in Wuhan City, so as to provide the evidence for improving the detection of HIV testing among young students. Methods: Fifteen PHSIs were sampled using a stratified random sampling method in 14 districts of Wuhan City, and school students at ages of 15 to 24 years were sampled from each district using a convenience sampling method. Participants' demographics, awareness of AIDS-related knowledge, HIV testing and willingness to receive HIV testing were collected using questionnaires, and factors affecting the willingness to receive HIV testing in PHSIs were identified among school students using a multivariable logistic regression model. Results : A total of 301 questionnaires were allocated, and 299 valid questionnaires were recovered, with an effective recovery rate of 99.34%. The respondents included 143 men (47.83%) and 156 women (52.17%), and had a mean age of (19.36±2.40) years; there were 223 respondents with an educational level of diploma and above (74.58%). The awareness of AIDS-related knowledge was 71.57% among the respondents, and 144 respondents had received AIDS-related health education in PHSIs (48.16%). There were 34 respondents that had received HIV testing (11.37%) and 203 respondents that were willing to receive HIV testing in PHSIs (67.89%). The respondents that were unwilling to receive HIV testing in PHSIs were mainly attributed to considering to be unlikely to get HIV infections (82.29%). Multivariable logistic regression analysis showed that school students who knew AIDS-related knowledge (OR=2.797, 95%CI: 1.583-4.941), knew free HIV counseling and testing services in PHSIs (OR=2.070, 95%CI: 1.123-3.814), and had received AIDS-related health education in PHSIs (OR=2.814, 95%CI: 1.573-5.032) were more willing to receive HIV testing in PHSIs. Conclusions There were 67.89% of school students that were willing to receive HIV testing in PHSIs in Wuhan City, and the willingness to receive HIV testing was correlated with the awareness of risk of HIV infections, and awareness and experience of AIDS control services in PHSIs.

Alzheimer's disease (AD) has become one of the most important and most interesting focuses in the field of medical and scientific research. Up to now, the pathogenesis of AD has not been completely clarified. However, the high-density of amyloid β-protein (Aβ) in senile plaques of AD brain and the neurotoxicity of Aβ have been indisputable facts. The mechanisms underlying Aβ neurotoxicity are very complicated, involving calcium overload, inflammation, ion channel dysfunction, oxidative stress and so on. Among all of those, the mechanism of oxidative stress in Aβ neurotoxicity and the experimental progress of antioxidants in AD treatment have been widely reported in recent years. This review mainly discussed current research progresses on the oxidative stress of Aβ, so as to provide readers with some clues to the antioxidant therapy of AD.
