Objective To investigate the correlation between serum levels of 25 hydroxyvitamin D and immunoglobulin E(IgE)in adults.Methods There were 1 969 participants over the age of 19 were enrolled in this studied,serum total IgE,dermatophagoides farinae(Df)-specific IgE,and serum 25(OH)D levels were analyzed.Other variables included sex,age,body mass index,smoking history,and economic status were collected.Adjusted regression analysis was used to examine the independent association of 25(OH)D with serum IgE levels.Results The average serum 25(OH)D level of 1 969 patients was(18.0±6.5)μg/L,the prevalence of asthma,allergic rhinitis,and atopic dermatitis were 15.2％(299/1 969),2.8％(63/1 969)and 3.0％(68/1 969)respectively,however,there was no significant difference in serum 25(OH)D levels in patients with allergic rhinitis.All subjects were divided into four groups according to the serum 25(OH)D level: Q1:less than and equal to 13.4 μg/L,Q2:more then and equal to 13.4 μg/L but less then and equal to 17.0 μg/L,Q3: more then and equal to 17.0 μg/L but less then and equal to 21.7 μg/L,and Q4: more than and equal to 21.8 μg/L.The median TIgE level increased with higher quartiles in the Kruskal-Wallis test.The prevalence of Df in Q1,Q2,Q3,Q4 group were 39.8％,33.2％,38.7％and 43.1％,respectively.Linear regression analysis indicated that 25(OH)D levels were positively correlated with lgTIgE(regression coefficient:0.011,95％CI 0.001-0.021),25(OH)D in male patients with dust mite allergy was positively correlated with lgTIgE(regression coefficient:0.026,95％CI 0.010-0.043).There was no significant correlation between 25(OH)D and lgTIgE in the other groups.Conclusion Adult serum 25(OH)D levels is positively correlated with total IgE levels.

Objective To analyze a rare genotype with β-thalassemia intermadia.Methods Phenotypic analysis was performed using routine hematological tests to measure red blood cell parameters and high performance liquid chromatography (HPLC)was used to measure hemoglobin fractions.The β-globin gene mutations were conducted using reverse-dot-blot and DNA sequencing of the breakpoint region were characterized with gap-PCR.Results The proband had a trait of thalassemia intermedia with reduced hemoglobin (86 g/L).The proband's father had a trait of microcytic hypochromic with reduced mean corpuscular volume(MCV),mean corpuscular hemoglobin (MCH) (63.7 fl and 20.4 pg,respectively) and an elevated level of HbA2.He had the phenotype of heterozygosity for β-thalassemia.The preband's mother,grandmother and sister had a trait of heterezygote for hereditary persistence of fetal hemoglobin (HPFH) with elevated level of HbF,which were 28.3%,21.1% and 33.7%,respectively.After molecular characterization of the family members,the proband was identified as a patient with β-thalassemia intermedia caused by co-existence of β-thalassemia(β41-42) and HPFH-6.The father was heterozygoas for β-thaiassemia (β41-42/βN) and the mother,grandmother and sister were all heterozygons for HPFH-6.Condusions A rare β-thalassemia intermedia case resulting from compound heterezygote of β41-42 with HPFH-6 is found.This study may provide clinical experiences for antenatal diagnosis.

Objective To observe the effect of pentylenetetrazole(PTZ)-kindled epliepsy on rat's learning and memory and the expression of calmodulin dependent protein kinaseⅡ(CaMKⅡ)in hippocampal neurons.Methods The rats were injected intraperitoneally with PTZ to establish the kindled models.The changes of behavior were evaluated through Morris water maze and the expression of ?-CaMKⅡ in hippocampal neurons was observed by immunohistochemistry technique.Results The Morris water maze test showed that the escape latency and the swimming distance in PTZ-kindled rats increased significantly(P

Objective To investigate clinical characteristics,diagnosis,treatment and prognosis of mucormycosis in patients with renal failure. Methods We reported a 65-year old case of mucormycosis with chronic renal failure. The patient was successfully treated with amphotericin B. Mucormycosis complicated with renal failure were reviewed excluding mucormycosis peritonitis associated with peritoneal dialysis and desferrioxamine-related mucormycosis. Results Fifteen cases including our case were involved with mean age of 49.87?15.84 years old. Rhinocerebral,pulmonary,and disseminated forms accounted for 46.7%,33.3% and 20% respectively. Autopsy was made in 46.7% of patients. Mortality was 73.3% in all of them and 42.9% in seven patients who received antifungal therapy. All patients without treatments died. Conclusion Mucormycosis is a lethal invasive infection in patients with renal failure. The management to improve prognosis are early diagnosis,surgical debridement,drainage and aggressive antifungal chemo-therapy.

Objective To investigate the effects of extended care on the treatment compliance and the quality of life on discharged elderly patients with chronic heart failure. Methods One hundred and eight patients were randomly assigned to the experimental group and the control group with 54 patients in each, the experimental group received extended care for 1 year, including regular telephone and visit follow-up, supporting medical care, diet care, rehabilitation exercises and supervision of self-care. The control group underwent routine health education before discharge. Medical compliance and self-management ability were compared three months, six months and 1 year after discharge, evaluation score of life quality were also compared at discharge and one year after discharge between the two groups. Results There were no significant differences in medication, diet and regular follow-up visits between the two groups. However, the patients in the experimental group showed better compliance than the control group in the self-testing of urine, body weight,and recording of symptoms, body signs and required exercises. Additionally, the patients in the experimental group had higher scores than the control group in the daily life-skills, happiness and the quality of life. Conclusions The extended care significantly improved the treatment compliance and the quality of life in the elderly patients with chronic heart failure.

Objective To investigate the cause of an outbreak of tinea capitis in a primary school.Methods All of the exposed children were surveyed by physical examinations and mycological examina-tions,including KOH preparation and fungal culture.The environment was also investigated in the school.With molecular typing of M.canis isolated from the patients and the environment,random primer amplifica-tion polymorphic DNA(RAPD)method,specific amplification of subrepeat elements in ribosomal DNA non-transcribed spacer(NTS),and DNA sequencing in intertranscribed spacer(ITS)of rDNA were performed.Results The total number of exposed children was seventy-one,among which fourty-two were suffered from tinea capitis.The ratio between boys and girls was13∶1.The age of the patients ranged from3.5-10years old.Four patients bred cats or dogs as pets.Fourty-one patients had noninflammatory type of tinea capitis and one had inflammatory type.Under microscopy all affected hairs showed ectothrix infection.M.canis was isolated from the patients,as well as from carpets in gymnasium and pillowcases in the school.The patterns of all strains of M.canis were identical in both RAPD and PCR amplification of rDNA NTS region.The same DNA sequence was found in the ITS region of isolates from the patients and the environment.Conclusion The outbreak of tinea capitis was caused by M.canis.M.canis strains isolated from the patients and from the environment were probably the same origin.

Objective To explore the characteristic of intelligence, personality and mentality of patients with intractable epilepsy and analyzethe related factors on intelligence. Methods 68 patients with intractable epilepsy and 60 healthy persons were assessed with Raven'sstandard progressive matrices (SPM), Eysenck personality questionnaire (EPQ) and 90 symptoms checklist (SCL-90). The related factors onintelligence were analyzed. Results Compared with controls, the total score and IQ of SPM of the patients decreased significantly (P<0.05).There were 51.4% of intellectual deficiency in patients with intractable epilepsy, which was higher than that of controls (1.7%) (P<0.05).There was no significant difference in score of EPQ and the proportion of personality type between 2 groups (P>0.05). The total score ofSCL-90 and the factor score, such as somatization, interpersonal sensitivity, depression, anxiety and hostility in patients were higher thanthose in controls(P<0.05). Various factors, including the onset age, course of disease, seizure types, frequency, duration, number of drug, thescores of SCL-90 were correlated with the intelligence of epileptic patients (P<0.05). Conclusion The intelligence of many patients with intractableepilepsy were damaged, and many patients were with various psychological barriers. The onset age, course of disease, seizuretypes, frequency, duration and number of drug were important factors related with intellectual disorders in patients with intractable epilepsy.
