Objective To investigate the status and clinical and epidemiological characteristics of human metapneumovirus (hMPV) and human bocavirus (HBoV) infections in children with acute respiratory tract infections (ARTIs) in Taiyuan. Methods A total of 549 children with ARTIs from November 2012 to May 2013 and November 2013 to May 2014 were recruited. The pharyngeal swab specimens were collected. The hMPV and HBoV were detected by using real-time PCR. Results In 549 children, 56 children (10.2%) were hMPV positive on swab specimens, 15 children (2.7%) were HBoV positive on swab specimens. The detection rates of hMPV and HBoV in November 2012 to May 2013 were 12.3%and 2.0%, respectively, and in November 2013 to May 2014 were 6.5%and 4.0%, respectively. The detection rate of hMPV was signiifcantly different between two periods (P<0.05), while the detection rate of HBoV has no signiifcant difference between two periods. In different months, the detection rate of hMPV and HBoV showed no signiifcant difference. The highest detection rates of hMPV and HBoV were all in children younger than two years old. The highest detection rate of hMPV was in children with asthmatic bronchitis or bronchiolitis. Conclusion In Taiyuan, during the monitoring periods, the ARITS are associated with childhood hMPV and HBoV infection especially in infants and toddlers. hMPV is one of the most important pathogens in infants and toddlers with wheezing.

OBJECTIVE: To study the influence of the number and position of anchor nails on the Bankart repair by the finite element analysis. METHODS: The 3D CT data of shoulder joints including normal adult volunteers were imported into Mimics 10.0 and Geomagic 2012 software to reconstruct the related tissues, and then meshed in Hypermesh 13.0 software to give material attributes. The position and number of MPC constraints were adjusted in Abaqus 6.14 to establish finite element model of shoulder joint under 6 working conditions including A model(normal control model), B model (Bankart damage control model), C model (1 anchor), D model (2 anchors), E model (3 anchors), F model (4 anchors). The humerus external rotation and forward load were added to simulate the fear test of the shoulder joint forward instability. RESULTS: (1)Normally, the inferior glenohumeral ligament complex accompanied by the external rotation of the humerus head has a wrinkle and a significant stress concentration around its anterior and posterior bundle terminations.(2)The stress of the anterior bundle and posterior bundle of the inferior glenohumeral ligament were increased by 52.33% and 45.67% respectively after Bankart's injury.(3)In each model of anchor repair, the stress concentration was obvious at the anchor site, and the stress of anterior and posterior bundle ligaments could be reduced; there were no obvious differences between C, D models and B model(>0.05), and there were significant differences between E, F models and B model(<0.05). CONCLUSIONS One or two anchors can reduce the stress of the anterior and posterior bundles of the inferior glenohumeral ligament in the repair of Bankart's injury, but when the angle of rotation is large, the stress concentration in the anchor position increases significantly, leading to the increases of the risk of failure. The application of three or four anchors can enhance the constraints on the inferior glenohumeral ligament and reduce the stress of the anchor itself through the "load sharing" effect between anchors, so as to ensure the stability of the shoulder joint and provide a mechanical environment for the early rehabilitation of patients.

Objective: To explore the key points of diagnosis and treatment of familial Mediterranean fever(FMF). Method: The clinical data of 3 cases with FMF misdiagnosed as Juvenile idiopathic arthritis(JIA)seen from January 2014 to June 2016 in Peking Union Medical College Hospital were retrospectively collected. The clinical manifestations, gene mutation characteristics, treatment and prognosis were also evaluated. Result: Two cases were male and 1 was female. The mean age of onset was 17 months (3 months to 36 months), while the average age of diagnosis was 6 years and 8 months (24 months to 11 years). All the 3 cases presented with periodic fever, red rash and arthritis.Two of them suffered from anemia, 2 of them showed lymphadenopathy, and 1 of them presented with hepatosplenomegaly. All of the 3 cases were diagnosed as JIA by excluding infectious diseases and neoplastic diseases and respondiug poorly to anti-infection treatment, but they benefitted little from glucocorticoids and a variety of immunosuppressive therapy. The mutations of MEFV gene were found in 3 cases by gene detection, and all of them were complex heterozygous mutations. Four reported pathogenic mutations were found: R202Q, E148Q, L110P, P369S. All the 3 cases are currently receiving oral colchicine (in accordance with the initial dose of children under the age of 5 recommended ≤ 0.5 mg/d, 5 to 10 years old children 0.5-1.0 mg/d, 10 years old children and older children 1.0-1.5 mg / d) , and the symptoms were significantly improved. Conclusion The familial Mediterranean fever can be characterized by repeated remittent fever, red rash, arthritis, and is easy to be confused with JIA in clinical manifestation.In this paper, 3 cases were diagnosed as complex heterozygous MEFV gene mutation by gene analysis.During the 6 months follow-up, all of the 3 patients responded well to colchicine.

OBJECTIVE: To evaluate the inhibitory role of a novel oncolytic adenovirus (OA), GP73-SphK1sR-Ad5, on the growth of hepatocellular carcinoma (HCC). METHODS: GP73-SphK1sR-Ad5 was constructed by integrating Golgi protein 73 (GP73) promoter and sphingosine kinase 1 (SphK1)-short hairpin RNA (shRNA) into adenovirus serotype 5 (Ad5), and transfecting into HCC Huh7 cells and normal human liver HL-7702 cells. The expression of SphK1 and adenovirus early region 1 (E1A) was detected by quantitative real-time PCR (qRT-PCR) and western blot, respectively. Cell viability was detected by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay, and apoptotic rate was determined by flow cytometry. An Huh7 xenograft model was established in mice injected intratumorally with GP73-SphK1sR-Ad5. Twenty days after injection, the tumor volume and weight, and the survival time of the mice were recorded. The histopathological changes in tumor tissues were observed by hematoxylin-eosin (HE) staining and transmission electron microscopy (TEM). RESULTS: Transfection of GP73-SphK1sR-Ad5 significantly upregulated E1A and downregulated SphK1 in Huh7 cells, but not in HL7702 cells. GP73-SphK1sR-Ad5 transfection significantly decreased the viability and increased the apoptotic rate of Huh7 cells, but had no effect on HL7702 cells. Intratumoral injection of GP73-SphK1sR-Ad5 into the Huh7 xenograft mouse model significantly decreased tumor volume and weight, and prolonged survival time. It also significantly decreased the tumor infiltration area and blood vessel density, and increased the percentages of cells with nucleus deformation and cells with condensed chromatin in tumor tissues. CONCLUSIONS GP73-SphK1sR-Ad5 serves as a novel OA and can inhibit HCC progression with high specificity and efficacy.

This study aimed to evaluate the cost-effectiveness of Chaiyin Granules compared with Oseltamivir Phosphate Capsules in the treatment of influenza(exogenous wind-heat syndrome). Based on a randomized, double-blind, positive drug parallel control clinical trial, this study evaluated the pharmacoeconomics of Chaiyin Granules with cost-effectiveness analysis method. A total of 116 patients with influenza from eight hospitals(grade Ⅱ level A above) in 6 cities were selected in this study, including 78 cases in the experimental group with Chaiyin Granules and Oseltamivir Phosphate Capsules placebo, and 38 cases in the control group with Oseltamivir Phosphate Capsules and Chaiyin Granules placebo. The total cost of this study included direct medical cost, direct non-medical cost, and indirect cost. The remission time of clinical symptoms, cure time/cure rate, antipyretic onset time/complete antipyretic time, viral nucleic acid negative rate, and traditional Chinese medicine(TCM) syndrome curative effect were selected as the effect indicators for cost-effectiveness analysis. Four-quadrant diagram was used to estimate the incremental cost-effectiveness ratio. The results showed that Chaiyin Granules were not inferior to Oseltamivir Phosphate Capsules in the remission time of clinical symptoms of influenza(3.1 d vs 2.9 d, P=0.360, non-inferiority margin was 0.5 d). Compared with Oseltamivir Phosphate Capsules, Chaiyin Granules would delay the remission time of clinic symptoms of influenza for 1 d, but could save 213.9 yuan. 1 d delay in cure time could save 149.3 yuan; 1% reduction in the cure rate could save 8.2 yuan; 1 d delay in antipyretic onset time could save 295.4 yuan; 1 d delay in complete antipyretic time could save 114.3 yuan; 1% reduction in the 5-day cure rate of TCM syndrome could save 19.2 yuan. Different from other indicators, there was no statistically significant difference between two groups in the effect of negative conversion rate of viral nucleic acid, but the cost was lower and the effect was superior, and the pharmacoeconomics was not different from that of Oseltamivir Phosphate Capsules in the field of influenza treatment.
