Method ELISA was used to test cord blood EPO and ET-1 in 54 high risk neonates as subjects and 14 healthy neonates as controls.Results The cord blood EPO levels in amniotic fluids turbid Ⅲ degree group and group eclampsia/pre - eclampsia were higher than those in control group (t= 4.0842,3 680 allP

Objective To analyze the correlation between clinical features and renal dysfunction in patients of acute lacunar infarction with progressive cerebral microbleeds (CMBs). Methods Two hundred and sixty-five patients with first-episode acute lacunar infarction were selected. The serum creatinine was measured within 24 h of admission and the estimated glomerular filtration rate (eGFR) was calculated. The brain MRI (including gradient-echo images) was examined within 2 d of admission and after 1 years of follow-up, respectively. The progressive CMBs was assessed with microbleeds anatomical rating scale (MARS), and the patients were divided into progressive CMBs group (progressive group, 42 cases) and non progressive CMBs group (non progressive group, 223 cases). The clinical features of 2 groups were compared and the correlation between progressive CMBs and renal dysfunction was analyzed. Results The age, 24 h pulse pressure, incidences of renal dysfunction and CMBs in progressive group were significantly higher than those in non progressive group: (69.8 ± 5.8) years vs. (61.5 ± 4.9) years, (63.3 ± 3.1) mmHg (1 mmHg=0.133 kPa) vs. (51.8 ± 4.2) mmHg, 69.0％(29/42) vs. 39.9％(89/223) and 57.1％(24/42) vs. 25.1％(56/223), and the platelet was significantly lower than that in non-progression group:(168 ± 35) ×109/L vs. (189 ± 40) ×109/L, and there were statistical differences (P<0.05 or<0.01). The Logistic regression analysis result showed that renal dysfunction and CMBs were Independent risk factors of progressive CMBs (OR = 1.571 and 1.054, 95％ CI 1.042 - 2.493 and 1.010 - 1.142, P<0.05). Conclusions The rate of renal dysfunction is higher in patients of acute lacunar infarction with progressive CMBs, and progressive CMBs are associated with renal dysfunction.

Objective To investigate the relationship between different topographic locations and neurological deteriorations (ND) in patients with acute new isolated pontine infarction.Methods One hundred sixty-eight patients with acute new isolated pontine infarction during arch 2012 to March 2016 were identified by diffusion weighted imaging (DWI) for retrospective review.Patients were divided into two groups according to their clinical symptoms:patients with ND and patients without ND.According to neuroimaging of DWI,the topographic location of pontine infarction was divided into three types:The upper,middle,and lower ones,and the correlations of ND with risk factors,laboratory examination results,clinical manifestations and different topographic locations were explored by statistical tests.Results Of 168 patients,26.8％ (45/168) were diagnosed with ND,and 73.2％ (123/168) were diagnosed without ND.Univariate analysis showed that there were differences in female ratio [62.2％ (28/45) vs 41.5％ (51/ 123)],smoking ratio [13.3％ (6/45) vs 26.0％ (32/123)],mean length of hospital stay [(22.83 ± 7.12)d vs (19.31 ± 7.65)d],ratio of worse short-term clinical outcomes [77.8％ (35/45) vs 33.3％ (41/123)],and ratio of lower pontine infarction [55.6％ (25/45) vs 26.0％ (32/123)] between two groups (P ＜ 0.05).Logistic regression analysis showed that lower pontine infarction was the independent risk factor of ND (OR =1.953,95％ CI:1.092-3.535,P =0.029).Conclusions Topographic location of lower pons lesions may be reliable predictor of ND in acute new isolated pontine infarction.

OBJECTIVETo investigate the clinical characteristics and therapeutic outcomes of non-Hodgkin lymphoma (NHL) occurring after renal transplantation.

METHODSWe reviewed a total population of 2045 adult kidney recipients between January 1998 and October 2012, 12 of which developed NHL. Their clinical features and outcomes were analyzed.

RESULTS12 patients with a median age of 52.5 (range: 30-68) years old, including 5 males and 7 females, were diagnosed as diffuse large B-cell lymphoma (DLBCL) at a median interval of 84 (range: 12-253) months after transplantation. The incidences of developing NHL at 2-year, 5-year and 10-year were 0.10%, 0.15% and 0.44%, respectively. The locations of lymphoma were diverse, including central nervous system, stomach, liver, kidney, pancreas, uterus, ribs, sKin, soft palate and Waldeyer ring. After reduction of immunosuppression intensity, 3 cases received surgical therapy, 6 cases with chemotherapy, 1 case with surgery combined with chemotherapy, 1 case with chemotherapy combined with irradiation and 1 case without treatment. The overall response rate was 81.8%, including 8 cases with CR, 1 with PR and 2 with progression. During a median of 11.5 (range: 1 to 130) months follow-up, 3 patients died.

CONCLUSIONNHL was a rare but serious complication after renal transplantation occurred with bimodal distribution, which was symptomatic diversity and non- specificity. The most histopathological type was DLBCL. Reduction of immunosuppression intensity was not enough to get efficacy, and CHOP with or without rituximab was effective in the treatment of NHL after renal transplantation.

Objective:To analyze the characteristics of respiratory pathogen spectrum in adult patients with acute exacerbation of bronchiectasis and its correlation with the severity of disease.Methods:A total of 108 patients with stable bronchiectasis from January 2014 to May 2018 in the Third People′s Hospital of Haikou City were enrolled. Sputum bacteria were cultured and common respiratory viruses in sputum and nasal swabs were detected by fluorescence quantitative polymerase chain reaction(PCR). All bronchiectasis patients were followed up for 1 year. Sputum bacteria culture and PCR virus detection were performed again in patients with acute exacerbation, and the differences of respiratory pathogen spectrum in patients with different severity of acute exacerbation were compared.Results:During the follow-up period, there were 53 cases of acute exacerbation events and a total of 91 case-times (up to 5 times per patient). The positive rates of sputum virus and nasal swab virus in patients with acute exacerbation were significantly higher than those in patients with stable period [39.6% (36/91) vs. 15.1% (8/53) , 45.1% (41/91) vs. 9.4% (5/53) ], and there were significant differences ( χ2=8.460, 13.621, P<0.05). However, the total positive rate of sputum bacterial culture in acute exacerbation and stable period had no significant difference ( P>0.05). The positive rate of Pseudomonas aeruginosa [0, 34.6% (9/26) ,52.4% (22/42) ] and rhinovirus [8.7% (2/23) ,3.8% (1/26) ,23.8% (10/42) ] in sputum among mild patients (16 cases, 23 case-times), moderate patients (16 cases, 26 case-times) and severe patients (21 cases, 42 case-times) in acute exacerbation stage were significant differences ( P<0.05). The levels of C-reactive protein (CRP) and interleukin (IL)-8 in patients in mixed infection of bacteria and viruses group in acute exacerbation stage were significantly higher than those in negative group, bacteria group and viruses group [CRP: (45.6 ± 23.0) mg/L vs. (11.2 ± 2.7) , (32.3 ± 10.2) , (21.3 ± 8.0) mg/L; IL-8: (9.0 ± 2.5) ng/L vs. (1.5 ± 0.9) , (1.8 ± 1.1) , (2.0 ± 1.3) ng/L], and there were significant differences ( F=23.012, 9.926, P<0.05). The hospitalization rate of patients in mixed infection of bacteria and viruses group was significantly higher than that in negative group, bacteria group and viruses group [29.6% (8/27) vs. 0, 16.7% (4/24) , 1/18] , and there were significant differences ( χ2=7.691, P<0.05). Conclusions:The positive rate of respiratory viruses in acute exacerbation of bronchiectasis in adults is significantly higher than that in stable stage. Pseudomonas aeruginosa and rhinovirus are the main infections in moderate and severe patients, Haemophilus parainfluenzae and influenza A virus are the main infections in mild patients, and the patients with mixed infection of bacteria and viruses have severe systemic inflammatory reaction and high hospitalization rate.

This study was aimed to investigate the genetic characteristics, identification method and transfusion strategy of rare blood type B(A). The rare blood group B(A) was typed by serological technique, PCR-SSP genotyping and sequencing of exon 6, 7 of ABO blood group. The genetic characteristics and molecular mechanism of B(A) blood group were also analyzed. Blood group compatibility test was conducted between blood donors of B(A) and recipients by clinical transfusion. The results showed that both forward and reverse grouping did not match the 3 cases of serological result in their family survey, while all of the 3 cases were grouped as AB blood group by forward grouping, B blood group by reverse grouping with serological result and B(A)04/001 group were genotyped by ABO genotyping. The patient of B blood group was transfused by 1 bag of washed red blood cells of donor of B(A) under closely monitoring, the patient's condition changed, and a mild adverse transfusion reaction was appeared. Washed red blood cell of O blood group was transfused into B(A) patient without blood transfusion reaction. It is concluded that the forward ABO serological grouping and reverse ABO serological grouping are not compatible, that may be verified by family survey and molecular biological methods. If in some cases transfusion therapy was applied, and group B(A) can not be transfused to the patient with group B or AB. Thus, transfusion compatibility or autologous transfusion can be adopted to transfuse to the patient from group B(A).

The prevalence of asthma and allergic disease has increased worldwide over the last few decades. Many common environmental factors are associated with this increase. Several theories have been proposed to account for this trend, especially those concerning the impact of environmental toxicants. The development of the immune system, particularly in the prenatal period, has far-reaching consequences for health during early childhood, and throughout adult life. One underlying mechanism for the increased levels of allergic responses, secondary to exposure, appears to be an imbalance in the T-helper function caused by exposure to the toxicants. Exposure to environmental endocrine-disrupting chemicals can result in dramatic changes in cytokine production, the activity of the immune system, the overall Th1 and Th2 balance, and in mediators of type 1 hypersensitivity mediators, such as IgE. Passive exposure to tobacco smoke is a common risk factor for wheezing and asthma in children. People living in urban areas and close to roads with a high volume of traffic, and high levels of diesel exhaust fumes, have the highest exposure to environmental compounds, and these people are strongly linked with type 1 hypersensitivity disorders and enhanced Th2 responses. These data are consistent with epidemiological research that has consistently detected increased incidences of allergies and asthma in people living in these locations. During recent decades more than 100,000 new chemicals have been used in common consumer products and are released into the everyday environment. Therefore, in this review, we discuss the environmental effects on allergies of indoor and outside exposure.
