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.

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 compare the efficiency and safety of aspirin-dipyridamole and warfarin in the prevention of thromboembolism in patients with nonvalvular atrial fibrillation(NVAF)and high risk factors.Methods One hundred and forty NVAF patients with high risk factors were randomly divided into two groups.Warfarin group[78 cases international normalized ratio(INR)2.0-3.0,for the patients older than 75 years,INR ranging from 1.6 to 2.5]and combination group(62 cases received aspirin 160 mg once every day plus dipyridamole 160 mg 3 times every day).The incidence of death,thromboembolism(including stroke and peripheral arteries embolism)and hemorrhage events were observed.Results Followed-up 12-28 months.In warfarin group,3 cases lost,2 cages had stroke,2 cases suffered from serious bleeding events,6 cases had minor bleeding events.In combination group,2 cases lost,6 cases had stroke,and 2 cases suffered from peripheral arteries embolism events,3 cases had minor bleeding events,but no serious bleeding events occurred.The incidence of thromboembolism in warfarin group wag,lower than that in combination group[2.7%(2/75)vs 13.3%(8/60),P<0.05].There was no significant difference of the bleeding rate between the two groups[10.7%(8/75)vs 5.0%(3/60),P>0.05].Conclusions Warfarin anticoagulative therapy is more effective than aspirin and dipyridamole antiplatelet dual therapy for the prevention of thromboembolism events in patients with NVAF and high risk factors.The major bleeding events in warfarin group occurs in patients with INR>3.0,so under intensive monitoring(INR 2.0-3.0),warfarin therapy is effective and safety.

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.

OBJECTIVETo evaluate the efficacy and safety of electroacupuncture at Tianshu (ST25) for patients with functional constipation (FC).

METHODSNinety-six patients with FC were randomized to receive deep needling on bilateral ST25 (group A, 48 cases) or shallow needling on bilateral ST25 (group B, 48 cases) with electroacupuncture once daily for 4 weeks. The proportion of patients with four or more complete spontaneous bowel movements (CSBMs) per week, and scores of constipation symptoms and satisfaction with treatment were compared between two groups. Safety was also assessed.

RESULTSThe proportion of patients with four or more CSBMs per week was 52.1% in group A, significantly higher than 25.0% in group B during the 4-week treatment (P<0.05). The constipation symptom score of patients were significantly improved in group A as compared with group B at week 2-4 (P<0.05). Patients in group A were more satisfied with their treatment compared with those in group B at week 1-4 (P<0.05). Five patients in group A felt significant pain and discomfort. No other adverse reaction was observed in both groups.

CONCLUSIONUsing electroacupuncture at ST25 to treat patients with FC is effectively, and deep needling had more stable effect than shallow needling.

OBJECTIVETo observe the intervention of liuwei dihuang pill (LDP) on therapeutic effectiveness and adverse reaction of hormonotherapy in treating nephrotic syndrome.

METHODSPatients allocated in two groups were medicated with initial dose of prednisone 1 mg/kg once a day at 8 am in the morning. After being medicated for 8 to 12 weeks, the dose of prednisone was decreased by 5.0 mg every 2 weeks till 0.5 mg/kg per day. Then the medication was changed to that two days' dosage orally take once a day with the daily dose reduced by 5.0 mg/kg every 2 to 3 weeks, and maintained at 0.4 mg/kg once every two days. At same time, necessary symptomatic treatment was given. To the treated group oral administration of LDP 8 capsules was given additionally, 3 times per day until prednisone decreased to maintenance dose.

RESULTSTherapeutic effect in the treated group was significant better than that in the control group (P < 0.05). Urinary protein, plasma albumin, triglyceride (TG) and total cholesterol (TC) in both groups were obviously improved (P < 0.05 or P < 0.01). However, as compared with the control group, the improvement was better, and the recurrent rate was lower (P < 0.05) in the treated group. Scores of Yin-deficiency caused excessive Fire syndrome and incidence rate of adverse reaction in the treated group were lower than those in the control group (P < 0.05 or P < 0.01).

CONCLUSIONLDP can markedly improve the therapeutic effectiveness and counteract the adverse reaction of hormonotherapy in treating nephrotic syndrome, and reduce the recurrence of the disease.
