Objective:To examine the relationship between brain natriuretic peptide (BNP) and the recurrence of atrial fibrillation (AF) after successful electrical cardioversion (EC) by a meta analysis approach.Methods:Based on PubMed,Medline and China National Knowledge Infrastructure (CNKI) databases,related literatures,published from 1980-2008,were searched; a manual search was also performed.The included trials were analyzed by RevMan4.2 software for meta analysis.Results:Totally seven studies were finally included.The analysis revealed that the baseline BNP level were greater in patients with AF recurrence than those without AF recurrence,with the standardized mean difference in the BNP levels being 0.82 units (95% confidence interval 0.12 to 1.52).The test for overall effect Z-score was 2.30,with a P value of 0.02; there was significant difference.Conclusion:It is suggested that the higher BNP level after successful electrical cardioversion is associated with greater risk of AF recurrence.The level of BNP may serve as an indicator for AF recurrence after successful EC.

BACKGROUND: Hydroxyapatite/chitosan (HA/CS) complex may act as a drug carrier for drug release, but little is reported about the release amount and antibacterial effect of minocycline-HA/CS (Mino-HA/CS) complex. OBJECTIVE: To investigate the in vitro release and antibacterial property of Mino-HA/CS complex. METHODS: HA/CS and Mino-HA/CS were prepared using co-precipitation method. The surface and cross-section features of the complexes were observed under scanning electron microscopy. The porosities were measured according to Archimedes Principle. The release of minocycline hydrochloride was measured by high performance liquid chromatography with the simulated saliva as drug release media. In vitro antibacterial effect on Porphyromonas gingivalis and Staphylococcus aureus were measured by bacteria-inhibiting ring method. Biological toxicities were evaluated via cel counting kit-8cel proliferation assay. RESULTS AND CONCLUSION: The porosity of Mino-HA/CS was larger than that of HA/CS, with the average porosity of 53.99%. Single-day release amount of Mino-HA/CS could maintain at the level of 0.5-1 μg per day for a long-term. Bacteriostatic rings of Porphyromonas gingivalis and Staphylococcus aureus stil existed clearly after 7 days. Cel proliferation assays showed that Mino-HA/CS extract had the significant effect on promoting cel proliferation. These findings indicate that the Mino-HA/CS sustains the release of minocycline at a relatively stable level within a longer period, shows good inhibitory effect on Porphyromonas gingivalis and Staphylococcus aureus and promotes the proliferation of periodontal ligament cel s.

Objective To observe the clinical efficacy of auricular point sticking with magnetic bead in treating insomnia in hepatocirrhosis patients. Method Ninety patients with hepatocirrhosis complicated with insomnia were randomized into a treatment group and a control group, 45 in each group. The treatment group was intervened by auricular point sticking with magnetic bead, while the control group was by auricular point sticking with medical adhesive tape. After successive 2-week treatments, the Insomnia Severity Index (ISI) and the Evaluation Criteria of Therapeutic Efficacy for Mental Disorders were observed for evaluating the treatment result. Result The ISI was significantly improved in the treatment group after intervention (P<0.05), and the improvement was significantly different from that in the control group (P<0.05). The total effective rate was 86.7% in the treatment group versus 60.0% in the control group, and the difference was statistically significant (P<0.01). Conclusion Auricular point sticking with magnetic bead is easy-to-operate and can produce a satisfactory efficacy in treating insomnia of hepatocirrhosis patients.

Objective To approach the effects of full Marathon on striated muscle and renal function of Marathon amateurs without complaints. Methods A prospective self-paired design study was conducted. The amateurs without body discomfort, hematuria, brown urine, or persistent muscle pain within 1 week after the 2012 Xiamen International Marathon Race were enrolled voluntarily. The peripheral blood and random urine specimens of all subjects under static status 1 week before the race and after the race instantly (within 10 minutes after finishing the race) were collected to detect markers of renal function and striated muscle injury. Results Sixty-one subjects were included in the final analysis of the study with full Marathon of 42.195 km and mean race time of (297.05± 55.60) minutes. Compared with those under static status before the race, the markers of renal function including the levels of urinary N-acetyl-beta-D-glucusamidase [NAG (U/L): 64.00 (54.50, 85.50) vs. 9.50 (8.10, 11.50)], urinary β2-microspheres protein [β2-MG (μg/L): 261.00 (128.50, 1 608.00) vs. 66.60 (33.75, 123.00)], random urinary creatinine [UCr (μmol/L): 19 066.56±10 938.31 vs. 5 872.52±4 363.20] and serum creatinine [SCr (μmol/L): 129.97±25.84 vs. 97.39±14.51] immediately after the race were significantly increased (all P < 0.01); the markers of muscle injury including the levels of serum creatine kinase [CK (U/L): 864.00 (504.00, 1 644.00) vs. 164.00 (128.00, 256.00)], lactic dehydrogenase [LDH (U/L): 383.26±141.69 vs. 182.23±41.12], myoglobin [Mb (mg/L): 1 880.00 (1 080.00, 3 300.00) vs. 42.00 (36.00, 54.50)], alanine aminotransferase [ALT (U/L): 27.0 (19.5, 38.0) vs. 24.0 (15.0, 29.5)] and aspartate transaminase [AST (U/L): 52.07±25.13 vs. 28.28±11.86] were also significantly increased (all P < 0.01), and the increase in CK, Mb, and LDH were more significant. It was shown by correlation analysis that CK after race was negatively correlated with age (r = -0.352, P = 0.005) and body mass index (r = -0.271, P = 0.035), and it was positively correlated with racing time (r = 0.387, P = 0.002) and urinary β2-MG after the race instantly (r = 0.364, P = 0.004). Mb after race was negatively correlated with body mass index (r = -0.331, P = 0.009), and it was positively correlated with urinary β2-MG after the race instantly (r = 0.315, P = 0.013). LDH after race was negatively correlated with age (r = -0.275, P = 0.032) and body mass index (r = -0.377, P = 0.003), and it was positively correlated with urinary β2-MG after the race instantly (r = 0.424, P = 0.001). Conclusion Full Marathon could significantly impact striated muscle and renal function of Marathon amateurs without complaints.

Immune checkpoint inhibitors (ICIs) are currently used in the treatment of various tumors and play an important role in tumor treatment, resulting in many adverse reactions related to the immune system. Type 1 diabetes (T1DM) is a rare endocrine system complication, which is rarely reported at present. We report a case of T1DM after using ICIs to treat gastric cancer. The patient was a 34 year old male who developed diabetes ketoacidosis after 206 days of sintilimab monoclonal antibody use, with fasting blood glucose of 15.78 mmol/L and glycosylated hemoglobin of 8.6%. Islet related antibody: Glutamate decarboxylase antibody: 119.2 IU/mL; Insulin antibody:<2 IU/L. Fasting insulin: 0.21 mU/L; Fasting C-peptide: 0.12 μg/L. Through the analysis of patients' clinical data, it aims to improve clinicians' understanding of immune related type 1 diabetes and provide ideas for correct diagnosis and treatment.

Objective To investigate the distribution of age at onset and its influence on clinical characteristics in synovitis,acne,pustulosis,hyperostosis,and osteitis (SAPHO) syndrome.Methods We recruited 164 patients with SAPHO syndrome who presented to Peking Union Medical College Hospital from Jan 2004 to Mar 2015.All the patients were assessed for medical history,laboratory tests and imaging presentations.The distribution of age at onset was analyzed using Shapiro-Wilknormality test and Kolmogorov-Smimov test for mixed normal distribution.The influence of age at onset on clinical features was analyzed using Mann-Whitney U test and x2 test.Results A double-peak mixed normal distribution of age at onset of skin lesions was found in female patients with SAPHO syndrome,with means and standard deviations of (30±6) years (early-onset) and (51 ±7) years (late-onset) for each mixed normal distribution.The cut-off point was determined to be 42 years old.Nonetheless,a typical single-peak normal distribution of age at onset of skin lesions was observed in male patients.A significantly higher frequency of thoracic region pain [14/36 (38.9％) vs 6/70 (8.6％),x2=14.28,P＜0.01,spinal lesions revealed by bone scintigraphy [23/35 (65.7％) vs 23/66(34.8％),x2=8.79,P=0.003],and peripheral skeletal lesions revealed by bone scintigraphy [17/35 (48.6％) vs 17/66(25.8％),x2=5.33,P=0.021] were found in late-onset female patients compared with early-onset ones.Moreover,female patients with late onset had significantly higher hs-CRP level [(12±12) mg/L vs (9±11) mg/L;U=911.5,P=-0.042)],pain VAS (4.8±1.8 vs 4.0±2.1;U=948,P=0.036),and BASFI (3.0±2.2 vs 1.8±2.0;U=822.5,P=0.003) at baseline than those with early onset.Conclusion Female patients with SAPHO syndrome have a double-peak distribution of age at onset of skin lesions.Female patients with early and late onset of skin lesions exhibit distinct clinical characteristics.

In the past decades, people's work and life styles have dramatically changed during the rapid economic development and urbanization in China. A national survey reported that Chinese adults spend an average of 81% of daily time in indoor environment. Exposure to indoor air pollution plays key roles for human health but is likely to be neglected due on the relatively lower concentration levels and lower awareness among common people. Till now, published studies focus more on the pollution levels or the toxicological effects of indoor air pollutants but there is a lack of disease burden assessment attributable to indoor air pollution. In this review, several international studies were introduced on the disease burden estimation attributable to indoor air pollution, as well as the estimation methods. The current situation of national study was also reviewed. The strengths and limitations of the representative international studies were discussed. This review is helpful in providing data to guide the research on disease burden assessment attributable to indoor air pollution in China, and further helps to prioritize the indoor air pollution control based on disease burden ranking among pollutants and motivate public policies to protect the public health.

OBJECTIVETo investigate the clinical value of multiplex nested reverse transcription PCR (RT-nPCR) in screening acute myeloid leukemia(AML)fusion genes.

METHODSA novel multiplex RT-nPCR assay was developed to detect 16 AML-related fusion genes (AML1-EVI1, AML1-ETO, AML1-MDS1, AML1-MTG16, MLL-AF9, MLL-AF6, MLL-AF10, MLL-ENL, MLL-MLL, PML-RARα, PLZFRARα, NPM1-RARα, CBFB-MYH11, DEK-CAN, SET-CAN and TLS-ERG) according to 2008 WHO classification of AML. The chromosome reciprocal translocations of 356 AML cases were detected by multiplex RT-nPCR and karyotyping. The positive samples were further confirmed by split- out PCR and FISH.

RESULTSThe fusion genes were detected in 172 patients with the positive detection rate of 48.31%(172/356), which was higher than that of karyotyping (31.46%) (χ²=70.314, P<0.01). Multiplex RT-nPCR is superior to karyotyping and FISH in identifying the rare, cryptic chromosome translocation (χ²=96.074, P<0.01).

CONCLUSIONThe multiplex RT-nPCR used in this study can quickly, effectively and accurately screen the fusion genes in AML patients, which can provide important evidence for assessing diagnosis and treatment, and also provide necessary information for minimal residual disease (MRD) and prognosis.
