Responses of mouse lymphocytes to the soybean paste fermented by Korean traditional fashion was examined to clarify its effects in cytokine production in vitro. A fraction of the soybean paste (KFSP-100) was prepared by precipitation with ammonium sulfate and by filtration through ultrafiltration membrane. KFSP-100 were added into cultures of fresh mouse splenic cells in vitro. KFSP-100 significantly enhanced the amount of IL-6 and TNF-a produced by macrophages and IL-6 and IFN-r produced by lymphocytes. Production of IL-12 by macrophages was not much affected by KFSP-100 treatments. The most noticeable finding was the fact that lymphocytes treated with KFSP-100 proliferated to an exceeding numbers (more than 10 times to the control) in 72 hours. The KFSP-100-induced proliferative response was specific to B cells since almost all of the KFSP-100-induced cells in the cultures of splenic cells were B cells. Furthermore, such a proliferative responses were equally observed only in cultures of purified B cells but not in cultures of T cells. In thermostability test, the biologically active components of the KFSP-100 is assumed to be either linear protein or glycoprotein. KFSP-100 did not induce agglutination of lymphocytes demonstrated by lectins in the same cells. These observations suggest that KFSP-100 may be a novel mitogen for B lymphocytes. The component (s) responsible for the B cell proliferation in KFSP-100 might be a factor gained by natural fermentation. None of the fractions of not fermented soybean paste prepared by the same methods demonstrate the same effect.

Three SNaPshot multiplex assays were developed to test 23 coding region single nucleotide polymorphisms (SNPs) and one control region SNP outside hypervariable regions (HVR)I and II, which was aimed at increasing the discrimination power of the mitochondrial DNA (mtDNA) typing in forensic casework, and confirming haplogroup assignments of mtDNA profiles in both human population studies and medical research. The selected SNPs targeted the East Asian phylogeny. These multiplex assays were validated by comparing with the sequencing analysis of samples chosen randomly. The mtDNA variations of 100 unrelated individuals from the Wuhan population in China were examined and classified into 31 haplotypes, and the haplotype diversity was estimated to be 0.952. The multiplex SNaPshot method is rapid and robust, and suitable for large-scale screening studies of mtDNA variability.

Objective To evaluate the value of echocardiography in diagnosing infective endocarditis (IE) in children. Methods The shape, size, echogenicity, distribution of vegetations and valvular function of the heart were observed by transthoracic echocardiography (TTE) in 30 patients with suspected IE. We correlated TTE ifndings with the results of hemoculture and serologic test. Results Vegetations were observed in all patients by echocardiography:seven patients with tricuspid valve vegetations, two with mitral valve vegetations, three with pulmonary valve vegetations, three with main pulmonary artery vegetations, three with aortic valve vegetations, two with aortic valve abscess, and two with vegetations in right atrium. After anti-infection therapy, the size of vegetations in iffteen patients became smaller and the less echogenic than before. Vegetations disappeared in two patients. Vegetation was recurrent repeatedly in one case. Ten patients recovered after operation. Two severe cases died. Five patients underwent TTE again one week after the previous negative TTE. Of them, echocardiography demonstrated vegetations in three cases. However, no vegetations were found in rest two cases because antibiotics had been used at early stage. In addition, echocardiography demonstrated one patient with mitral valve vegetation. But the lesion was ifnally conifrmed to be operating suture. The sensitivity and specificity of TTE in detecting vegetations were 88.0% and 80.0%, respectively. Blood cultures were positive in twenty-seven cases and were negative in three cases. Conclusions The early diagnosis of IE is important to improve patient′s prognosis. It takes a long time in organism cultivation before achieving the clinical diagnosis. TTE can help obtain an early diagnosis stage of IE, and provide the assessment of size and location of vegetation. It plays an important role in treatment and prognosis prediction.

Objective To analyze the associations between particulate air pollution (PM10,PM25) and stroke daily attack or mortality. Methods Meta-analysis method was used to polysynthetically analyze 16 quantitative studies about the associations between particulate air pollution and stroke daily attack or mortality. The relative odds ratio(OR) of stroke attack or mortality associated with per 10 μg/m3 increase of particulate matter concentration was used as effective value,taking a sensitivity analysis for the results. Results A 10 μg/m3 increase in PM10was associated with a 1.09% (95%CI: 0.10%-2.08% ) increase in stroke daily attack (OR=1.011,95%CI: 1.001-1.021)and 0.70% (95%CI: 0.60%-0.80% ) increase in stroke daily mortality (OR= 1.007, 95%CI: 1.006-1.008). The results of sensitivity analysis supported above results. As for PM2.5 OR appeared to be 1.001 (95%CI: 0.992-1.010) with a 10 μg/m3 increase in stroke daily attack and 1.052 (95%CI:0.958-1.154) for daily mortality. Conclusion There are positive associations between PM10 and stroke daily attack and mortality, increase of PM25 was not associated with stroke attack and mortality.

Objective To investigate the pathogen-related genes of atmospheric polluting disease so as to clarify the biology mechanism and provide the scientific basis.Methods By using the technique of dot blot hybridization,we analyzed genes’differential expression with cloning by exposure to ≥75 μg/m3 PM2.5 in heating season and < 75 μg/m3 PM2.5 in un-heating season in WI-38 human embryo lung cells.The levels of cytokines TNF-α,IL-2, IL-6 and IL-8 were determined by radio immunity assay. Results After 24h of treatment, compared with control group,more than 100μg/mL PM2.5 significantly increased TNF-α,IL-6 and IL-8 levels,and decreased IL-2 in WI-38 human embryo lung cells (P < 0.05 ).The clear stripe was found in 350 bp in 48 gene samples with segment with differential expression of genes exposed to different concentrations of PM2.5 in WI-38 human embryo lung cells.Through the dot blot hybridization,black brown spots were found in 41 samples in Tester cDNA hybridization,and no similar spots were found in all of the same samples in Driver cDNA hybridization. Conclusion PM2.5 exposure may induce the inflammatory damage of WI-38 human embryo lung cells.Obvious genetic damage was observed in those cells exposed to ≥75 μg/m3 PM2.5 in heating season.

BACKGROUND:Dysphagia is one of common early complications after anterior cervical fusion. Medium and severe dysphagia often causes serious influence on the patients. A variety of factors have been shown to have a correlation with the postoperative dysphagia, but specific mechanism is stil unclear. OBJECTIVE:To explore the risk factors for dysphagia after single-level anterior cervical fusion. METHODS:From January 2011 to June 2013, data of 44 patients with dysphagia and 213 patients without dysphagia after single-level anterior cervical fusion were compared. The baseline data (age, gender, ethnicity, body mass index, smoking history, drinking history, hypertension, diabetes, course length, and type of cervical spondylosis) and perioperative data (intraoperative blood loss, internal fixation, the location of the operated level, operation time, and the side of operation approach) between two groups were compared by Logistic regression analysis to determine risk factors for postoperative dysphagia.RESULTS AND CONCLUSION:A total of 257 patients were included with a fol ow-up for 6 to 24 months postoperatively and 44 of them suffered from dysphagia after single-level anterior cervical fusion. The overal prevalence for postoperative dysphagia was 17.1%. Univariate analysis indicated that age, gender, the location of the operated level, and course length were associated with postoperative dysphagia. Logistic regression analysis of multivariate analysis demonstrated that independent predictors for postoperative dysphagia included gender (female), age (>60 years), the location of the operated level (C 4-5 , C 5-6 ), and course length (>12 months). Clinicians should give appropriate recognition and take corresponding measures to avoid it.

Background and purpose:Cancer-related pain is one of the most important symptoms of patients with advanced cancer. Chemotherapy sometimes induces peripheral neuropathy and pain. These symptoms seriously affect patients’ quality of life. Cancer pain assessment is now achieved by the subjective scales of patients, but lacking objective measurement. In this study, we used the neurotic electrophysiological method by way of PainVision system (PV system) to evaluate cancer pain quantitatively to detect and analyze degree of chemotherapy-induced neuropathy. Methods:We obtained numerical rating scale (NRS) scores from patients receiving analgesics and calculated the PainRatio from PV system at the same time. Then we analyzed the relationship between NRS and PainRatio scores. We detected current perception threshold (CPT) levels of patients receiving chemotherapy to ifnd the correlation between chemotherapy and CPT level, and attempt to evaluate chemotherapy-induced neuropathy.Results:PainRatio scores were linearly associated with NRS scores (Pearson correlation coeffcient=0.849,P<0.001). Patients with neuropathy symptoms got higher CPTs. However, no statistically signiifcant difference was observed between patients treated with oxaliplatin, paclitaxel and other agents.Conclusion:PainVision system can be used in cancer pain assessment quan-titatively, and be helpful in cancer pain assessment objectively. Patients with deifned neuropathy showed higher CPTs, indicating the potential clinical value of PV system in detecting and evaluating chemotherapy-induced neuropathy.
