Objective To understand the distribution of inhaled allergens throughout Hainan province and explore effective preventive measures against allergen by examining the serum allergen of patients with chronic rhinosinusitis (CRS), which will provide evidence for specific immunotherapy for treating CRS. Methods Three hundred and eighteen CRS patients underwent Phadiatop blood test by using the UniCAP 100 , a completely automatic autoanalyser. Allergen-specific IgE of 7 common allergens were tested and the concentration of total immunoglobulin E (TIgE) was collected and evaluated. Results The positive rates of the serum TIgE and inhaled allergens were 64.15% and 37.74% respectively. The incidences of the positive serum SIgE is 33.96%. Among the positive cases, 28.30% of the inhaled allergens were dermatophagoides pteronyssinus, 27.36% for tropical mites, 21.07% for dermatophagoides farinae, 13.52% for cockroach, 11. 64% for house dust, 7. 86% for cat dander and 0.63% for dog dander. The incidences of positive TIgE and SIgE were not significantly different between patients with nasal polyps and sinusitis only. Conclusions Dermatophagoides pteronyssinus, tropical mites and dermatophagoides farinae are the main inhaled allergens for CRS patients in Hainan.

Objective To investigate the relations between microRNA-451 (miR-451) expression and gastric cancer (GC).Methods Expression of miR-451 in tumor and paired non-cancerous tissues was measured by real-time quantitative polymerase chain reaction.The association of miR-451 expression with clinical pathological characteristics and prognosis was statistically analyzed;in addition,slow virus LV-mir-451 was applied to infect human gastric cancer cell line BGC-823 and MKN-45,and construct miR-451 over-expressed stable cell lines.Finally,to detect cell proliferation,migration and invasion.Results miR-451 expression decreased in GC tissues vs.pericarcinous tissues (0.010 ± 0.007 vs.0.014 ± 0.008,t =3.015,P ＜ 0.05),and its down-regulation positively correlated with lymphatic metastasis,clinical staging and shorter overall survival.miR-451 expression in BGC-823 and MKN-45 cells did not impact on cell proliferation,but did reduce migration rates (0.863 ±0.026 vs.1.107 ±0.032,t =9.820,P＜0.05;0.863 ±0.026 vs.1.060±0.054,t =4.369,P＜0.05) and invasion rates (1.040 ± 0.055 vs.1.522 ± 0.001,t =5.84,P ＜ 0.05;1.040 ± 0.055 vs.1.696 ± 0.078,t =10.16,P ＜ 0.05) in BGC-823 cells.Conclusions miR-451 may act as a prognostic marker in GC.

Objective:To investigate the MRI features of the primary sinonasal malignant melanoma (SMM) and evaluate the signal pattern based on T 1WI and T 2WI, in order to improve the diagnostic accuracy of SMM. Methods:The MRI findings of 63 SMM cases confirmed by pathology from April 2007 to November 2018 at Beijing Tongren Hospital, Capital Medical University were analyzed retrospectively. The signal intensity of malignant melanoma was classified into four types(Ⅰ—Ⅳ) according to the proportion of signal areas of the largest slice of the tumor on T 1WI and T 2WI. The classification criteria according to T 1WI: type Ⅰ, the area of hyperintensity was ≥50%; type Ⅱ, the area of hyperintensity was <50%; type Ⅲ, the tumor did not show hyperintensity, and the area of isointensity was ≥50%; type Ⅳ, the tumor did not have high signal area, and the area of low signal was ≥50%. The classification criteria according to T 2WI: type Ⅰ, the area of low signal in the tumor was ≥50%; type Ⅱ, the area of low signal was <50%; type Ⅲ, the tumor did not contain low signal area, and the area of isointensity was ≥50%; type Ⅳ, the tumor did not have low signal area, and the area of high signal intensity was ≥50%. The proportion of each type was calculated. Results:According to T 1WI, typeⅠwas identified in 27 cases (42.9%, 27/63), typeⅡ in 25 cases (39.7%, 25/63), type Ⅲ in 4 cases (6.3%, 4/63), and type Ⅳ in 7 cases (11.1%, 7/63). According to T 2WI, type Ⅰwas demonstrated in 29 cases (46.0%, 29/63), type Ⅱ in 28 cases (44.4%, 28/63), type Ⅲ in 2 cases (3.3%, 2/63), and type Ⅳ in 4 cases (6.3%, 4/63). There were 16 cases classified as type I based on T 1WI and T 2WI. Conclusions:Typical and atypical SMM can be identified according to signal patterns. The typeⅠsignal pattern of SMM cases on T 1WI and T 2WI is typical and can be easily diagnosed, but the proportion was less than 50%. For atypical SMM, malignant melanoma should be strongly suspected if hyperintense on T 1WI or hypointense on T 2WI is found.

OBJECTIVETo explore the risk factors of ventilator-associated pneumonia (VAP) in patients admitted in an intensive care unit (ICU) for pulmonary tuberculosis (TB).

METHODSThe clinical data of 143 patients admitted in the ICU at our center between January, 2014 and June, 2015 were reviewed. The patients with VAP and those without VAP were analyzed for risk factors of VAP in the setting of an ICU for pulmonary TB and compared for the duration of ventilation and hospital stay.

RESULTSThe patients with pulmonary TB showed a significantly higher incidence of VAP in the ICU than those without TB. Univariate analysis suggested that the occurrence of VAP was significantly correlated with the duration of mechanical ventilation, invasive examination, pulmonary tuberculosis, lung structure changes, use of multiple antibiotics, diabetes, tracheal incision, indwelling gastric tube, APACHE II score, and coma (P<0.05). Multivariate logistic regression analysis showed that pulmonary TB, duration of mechanical ventilation, APACHE II score, invasive operation, and use of multiple antibiotics were independent risk factors for VAP (P<0.05). The patients who developed VAP had a prolonged duration of mechanical ventilation and ICU stay (P<0.05).

CONCLUSIONPatients admitted in tuberculosis ICU are exposed to a high risk of VAP with a high mortality rate as the result of multiple interacting risk factors. Pulmonary TB, prolonged mechanical ventilation, an APACHE II score >15, invasive operation, and use of multiple antibiotics are all independent risk factors for VAP in tuberculosis ICU.

OBJECTIVETo observe the therapeutic effects of Qinggan Huatan Huoxue Recipe (QHHR) on patients with non-alcoholic steatohepatitis (NASH).

METHODSOne hundred and fifty NASH patients were randomly assigned to the treatment group (78 cases) and the control group (72 cases). QHHR was given to patients in the treatment groups, while Danning Tablet was given to those in the control group. The therapeutic course for all was three months. Before and after treatment changes of clinical symptoms and physical signs, liver imageology, liver functions, blood lipids, and insulin resistance index (IRI) were observed.

RESULTSCompared with before treatment, obvious improvement of clinical symptoms, weight, body mass index (BMI), liver functions, blood lipids, and integral of liver ultrasound B was obtained in the two groups (P < 0.05). The IRI of the treatment group was significantly reduced after treatment (P < 0.05). Better effects were obtained in lowering the body weight, BMI, alanine aminotransferase (ALT), gamma glutamyltransferase (gamma-GT), triglyceride (TG), total cholesterol (TC), integral of liver ultrasound B, and the total effective rate (P < 0.05).

CONCLUSIONSQHHR had definite effects on NASH. Its therapeutic effects were better than Danning Tablet.

OBJECTIVEThe Chinese Children's Leukemia Group (CCLG)-acute lymphoblastic leukemia (ALL) 08 protocol for childhood ALL was established in 2008. This study aims to evaluate the drug-related toxicities of CCLG-ALL 08 protocol in the treatment of childhood ALL.

METHODSA total of 114 children with newly diagnosed ALL were treated with the CCLG-ALL 08 protocol. The protocol was divided into five phases: remission induction (VDLD), early reinforcement (CAM), consolidation therapy, delayed reinforcement (DIa & DIb) and maintenance treatment. Drug-related toxicities in each phase were evaluated according to the Common Terminology Criteria for Adverse Events version 4.0.

RESULTSToxicities were more frequent in phase VDLD than other treatment phases, including hepatotoxicity (87.7%), dental ulcer (20.2%), hyperglycemia (20.2%), prolonged activated partial thromboplastin time (21.1%) and decreased fibrinogen (34.2%), with the incidence rates of severe adverse events at 7%, 0, 1.3%, 0.8% and 2.7% respectively. The incidence of allergic reaction to L-ASP was significantly higher in phase DIa than in phase VDLD (28.0% vs 7.9%; P<0.01), and there were no longer any allergic reactions in 15 patients who received continuing treatment with pegaspargase instead. There was no severe arrhythmia, myocardial ischemia, decreased left ventricular function, osteonecrosis, myopathy, organ failure or treatment-related mortality.

CONCLUSIONSThe drug-related toxicities of CCLG-ALL 08 protocol are common in phase VDLD, but they are mild and reversible. There is no treatment-related mortality. The CCLG-ALL 08 protocol for childhood ALL is safe.
