Background: Extracorporeal membrane oxygenation (ECMO) is performed as an acceptable life-saving bridging procedure in patients with severe acute respiratory distress syndrome (ARDS).To patients with avian influenza A (H7N9)-associated ARDS, ECMO could be adopted as a feasible therapeutic solution. We present our successful experience with ECMO utilized in a respiratory failure patient with H7N9 infection. Case presentation: A 44 years-old female with H7N9-induced ARDS was admitted to intensive care unit (ICU) and was treated with veno-venous ECMO for six days, antiviral therapy, prolonged corticosteroid infusion and other therapies. She suffered significant hemorrhage requiring transfusion of platelets and multidrug-resistant Acinetobacter Baumannii infection during ECMO support. Bleeding and infection almost killed the patient's life. Fortunately, she was alive at last and completly recovered after 38 days of ICU stay. Conclusions: ECMO was effective in this H7N9 patient with a fatal respiratory failure. Mechanical circulatory support was the only chance for our patient with H7N9-associated ARDS to survive until respiratory function recovery. Early detection and rapid response are essential to these serious ECMO-associated complications such as hemorrhage, thrombosis and infection. © 2017 The Author(s).

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Increasing evidence suggests that microRNAs (miRNAs) are associated with HCC tumorigenesis. The present study was designed to define the role of miR-141 in HCC. The expression of miR- 141 was significantly decreased in four HCC cell lines. Overexpression of miR-141 suppressed both the growth and the motility of HCC cells. Furthermore, we identified zinc finger E-box binding homeobox 2 (ZEB2) as a target of miR- 141 and miR-141 functioned as a tumor suppressor via ZEB2 targeting in HCC. These data provide a novel potential therapeutic target for HCC treatment. © International Society of Oncology and BioMarkers (ISOBM) 2014.

The major surface lipoglycan of Mycobacterium tuberculosis (M. tb), mannose-capped lipoarabinomannan (ManLAM), is an immunosuppressive epitope of M. tb. We used systematic evolution of ligands by exponential enrichment (SELEX) to generate an aptamer (ZXL1) that specifically bound to ManLAM from the virulent M. tb strain H37Rv. Aptamer ZXL1 had the highest binding affinity, with an equilibrium dissociation constant (K d) of 436.3 ± 37.84 nmol/l, and competed with the mannose receptor for binding to ManLAM and M. tb H37Rv. ZXL1 significantly inhibited the ManLAM-induced immunosuppression of CD11c + dendritic cells (DCs) and enhanced the M. tb antigen-presenting activity of DCs for naive CD4 + Th1 cell activation. More importantly, we demonstrated that injection of aptamer ZXL1 significantly reduced the progression of M. tb H37Rv infections and bacterial loads in lungs of mice and rhesus monkeys. These results suggest that the aptamer ZXL1 is a new potential antimycobacterial agent and tuberculosis vaccine immune adjuvant. © 2014 The American Society of Gene and Cell Therapy.

To evaluate the epidemiological features and control status of hypertension in rural area of The Three Gorges. A cross-sectional survey was carried out in rural area of Yiling District, Yichang City, which was located north-west bank of Xiling Gorges in 2007. A standard structure questionnaire was used to collect data on the hypertension history and treatment, social-economic status and life-styles, and so on. Blood pressure was measured by trained observers using standardized mercury sphygmomanometer. Hypertension was defined as systolic blood pressure ≥ 140 mm Hg (1 mm Hg = 0.133 kPa) and/or diastolic ≥ 90 mm Hg, or current treatment with antihypertensive medications. Hypertension control was defined as blood pressure levels of less than 140/90 mm Hg. A total of 9618 residents aged 35 years and above were included (response rate: 81.3%), and 19.7% residents were the Three Gorges migrants. The age-adjusted prevalence of hypertension was 37.3% for all, and 21.3%, 39.8%, 58.0% for aged 35 - 44, 45 - 59, ≥ 60 years, respectively. The age-adjusted rate was higher in men for all (39.1%) and aged 35 - 44 years (27.0%) than in women (36.3% for all and 17.8% for aged 35 - 44 years, P < 0.01). The age-adjusted rate of awareness, treatment and control rates of hypertension were lower in men (18.5%, 9.0%, 0.9%, respectively) than in women (23.5%, 13.6%, 2.0%, respectively, all P < 0.01). Among the participants with treated hypertension, the control rate of hypertension was only 17.0%. Prevalence and rate of awareness, treatment and control of hypertension were similar between migrants and non-migrants. The prevalence of hypertension is high, but the awareness, treatment, control rates were low in rural area of Yiling District. Efforts should be made to reduce the prevalence rate and to improve the control rate of hypertension in this area.

A total of 1844 patients with hand, foot, and mouth disease (HFMD), most of them were children of age 1-3-year-old, in Central China were hospitalized from 2011 to 2012. Among them, 422 were infected with coxsackievirus A16 (CVA16), 334 were infected with enterovirus 71 (EV71), 38 were co-infected with EV71 and CVA16, and 35 were infected with other enteroviruses. Molecular epidemiology analysis revealed that EV71 and CVA16 were detected year-round, but EV71 circulated mainly in July and CVA16 circulated predominantly in November, and incidence of HFMD was reduced in January and February and increased in March. Clinical data showed that hyperglycemia and neurologic complications were significantly higher in EV71-infected patients, while upper respiratory tract infection and C-reactive protein were significantly higher in CVA16-associated patients. 124 EV71 and 80 CVA16 strains were isolated, among them 56 and 68 EV71 strains were C4a and C4b, while 25 and 55 CVA16 strains were B1a and B1b, respectively. Similarity plots and bootscan analyses based on entire genomic sequences revealed that the three C4a sub-genotype EV71 strains were recombinant with C4b sub-genotype EV71 in 2B-2C region, and the three CVA16 strains were recombinant with EV71 in 2A-2B region. Thus, CVA16 and EV71 were the major causative agents in a large HFMD outbreak in Central China. HFMD incidence was high for children among household contact and was detected year-round, but outbreak was seasonal dependent. CVA16 B1b and EV71 C4b reemerged and caused a large epidemic in China after a quiet period of many years. Moreover, EV71 and CVA16 were co-circulated during the outbreak, which may have contributed to the genomic recombination between the pathogens. It should gain more attention as there may be an upward trend in co-circulation of the two pathogens globally and the new role recombination plays in the emergence of new enterovirus variants. © 2014 Liu et al.

A new self-microemulsifying mouth dissolving film (SMMDF) for poorly water-soluble drugs such as indomethacin was developed by incorporating self-microemulsifying components with solid carriers mainly containing microcrystalline cellulose, low-substituted hydroxypropyl cellulose and hypromellose. The uniformity of dosage units of the preparation was acceptable according to the criteria of Chinese Pharmacopoeia 2010. The SMMDF was disintegrated within 20 s after immersion into water, released completely at 5min in the dissolution medium and achieved microemulsion particle size of 28.81±3.26nm, which was similar to that of liquid self- microemulsifying drug delivery system (SMEDDS). Solid state characterization of the SMMDF was performed by SEM, DSC and X-ray powder diffraction. Results demonstrated that indomethacin in the SMMDF was in the amorphous state, which might be due to self-microemulsifying ingredients. Pharmacokinetic parameters in rats including Tmax, Cmax, AUC were similar between the SMMDF and liquid SMEDDS. AUC and Cmax from the SMMDF were significantly higher than those from the common mouth dissolving film or the conventional tablet, and Tmax from SMMDF group was also significantly decreased. These findings suggest that the SMMDF is a new promising dosage form, showing notable characteristics of convenience, quick onset of action and enhanced oral bioavailability of poorly water-soluble drugs. © 2013 Informa Healthcare USA, Inc.

Objective: To explore the epidemiological status and risk factors of hyperuricemia in rural area of the Three Gorges. Methods: A cross-sectional survey was carried out in rural area of Yiling District, Yichang City, which was located north-west bank of Xiling Gorge in 2007. A standard structure questionnaire was used to collect demographic data, social-economic status and life-style features. Fasting venous blood was collected and serum uric acid (SUA) was determined. Hyperuricemia was defined as SUA levels ≥417 μmol/L (70 mg/L) in men and ≥357 μmol/L (60 mg/L) in women. Multiple logistic regression analysis was used to analysed the risk factors of hyperuricemia. Results: A total of 9354 participants aged 35 and above were included, 19.9% (1866/9354) participants were the Three Gorges migrants. Serum uric: acid level in men was significantly higher than that in women [(285.1 ± 80.2) μmol/L vs. (210.3 ± 65.0) μmol/L, P < 0.01]. Serum uric acid level increased significantly in both genders in proportion to increase of age, and was higher in men than in women in all age groups (all P <0.01). The age-adjusted prevalence was significantly higher in men than in women (5.6% vs. 3.3%, P <0.01), and was also higher in men aged 35-44 and aged 45-54 than in women (both P < 0.01). There was no significance in prevalence of hyperuricemia in both men and women aged 55-64 and aged ≥65. After adjusting age, gender, educational level, migration and occupation, the multiple logistic regression analysis showed that the prevalence of hyperuricemia was higher in alcohol drinking participants than that of non-alcohol drinking participants (OR = 2.06, 95% CI: 1.59-2.67, P < 0.01), and in participants used to consume less green vegetables and fruits than in participants consuming more green vegetables and fruits (OR = 1.77, 95% CI: 1.27-2.47, P < 0.01). Conclusions: The prevalence of hyperuricemia is relatively low in rural area of the Three Gorges. Alcohol drinking and low intake of green vegetables and fruits are the risk factors of hyperuricemia in this population. Copyright © 2013 by the Chinese Medical Association.

The development of effective Mycobacterial antigen diagnostic reagents remains a high priority. The 6-kDa early secreted antigenic target (ESAT6) and 10-kDa culture filtrate protein (CFP10) are secreted early by virulent Mycobacterium tuberculosis (M. tb) and are not present in the non-virulent Bacillus Calmette-Guerin (BCG). In this study, we used a Systematic Evolution of Ligands by Exponential Enrichment (SELEX) technique to screen for a functional ssDNA aptamer "antibody" that specifically bound to ESAT6-CFP10 (CE) protein. The selected single ssDNA aptamers (CE24 and CE15) demonstrated the highest specificity and binding affinity to CFP10 (CE24: Kd=3.75×10-7M) and ESAT6 (CE15: Kd=1.6×10-7M). We further detected CFP10 and ESAT6 proteins in serum samples from active pulmonary tuberculosis (TB) patients, extrapulmonary TB patients and healthy donors by using an enzyme-linked oligonucleotide assay (ELONA). The results showed that the sensitivity and specificity were 100% and 94.1% (using CE24 aptamer-based ELONA) and 89.6% and 94.1% (using CE15 aptamer-based ELONA), respectively. A good correlation was observed between aptamer-based ELONA and T-SPOT TB assay. Thus, our study suggests that CE24 and CE15 have potentially broad applications as early antigen diagnostic agents not only for active pulmonary TB, extrapulmonary TB, but also possibly for latent TB infection and TB with immune-deficiency. © 2014 The British Infection Association.

Background:Many studies have investigated the associations between the signal transducer and activator of transcription 3 (STAT3) in the susceptibility to ulcerative colitis (UC) and Crohn's disease (CD). However, the results remain inconsistent. This meta-analysis determined the risk of STAT3 rs744166 polymorphism-conferred UC and CD susceptibility.Materials and Methods: Electronic databases, including PubMed, EMBASE and the Cochrane Library, were searched for all eligible studies that evaluated the association between STAT3 rs744166 polymorphisms with UC and CD risk up to August 21, 2014. The pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated using fixed- or randomeffects models.Results: Twelve studies containing 10298 patients with CD, 4244 patients with UC and 11191 controls were included in this meta-analysis. The results indicated that the STAT3 rs744166 polymorphism was associated with CD and UC susceptibility (CD: GA+AA vs. GG, OR = 1.20, 95%CI, 1.11 -1.30, /2 = 0%, Punadjusted<0.00001, PBonferroni<0.00005, PFDR< 0.00001 ; UC: GA+AA vs. GG, OR = 1.21, 95%CI, 1.08-1.36, /2=1%, Punadjusted = 0.001, PBonferroni = 0.005, PFDR = 0.00125). In subgroup analyses by ethnicity, the significant association was found only among Caucasians. However, when grouped by age of onset, positive associations were found both among adults and children. In addition, when stratified by study design and genotyping methods, the risk of CD was significantly associated with the STAT3 rs744166 polymorphism in hospital-based and population-based groups and in SNP Array and SNPlex groups. For UC, significant associations were also found in population-based, PCR-RFLP and SNPlex groups. Moreover, these findings were sufficiently robust to withstand the Bonferroni correction and false discovery rate (FDR).Conclusion: This meta-analysis indicates that carriers of the STAT3 rs744166 'A' allele have a significantly greater risk of CD and UC, especially among Caucasians. © 2014 Zhang et al.
