Objective To investigate the situation of subjective well-being feeling of type 2 diabetes patients and its influential factors.Methods One hundred and twenty-seven patients with type 2 diabetes were recruited as our subjects and all of them were performed the questionnaire investigation about well-being feeling.Influential factors were analyzed through several statistic methods.Results The index of subject wellbeing ranged from 3.70 to 13.70 and the average was 10.67 ± 2.10 of all type 2 diabetes patients.Of which The index of total affectation was 5.11 ± 0.92 and the range was from 2.63 to 6.63.The score of life satisfaction was 5.58 ± 1.22,and the range was from 1.10 to 7.70.Index of subjective well-being significantly associated with education,family income,therapy approach,HbA1 c level,complication,medicine burden.However there was no correlation with gender,age,diabetes duration.Conclusion The main types of subjective well-being feeling of patients with type 2 diabetes were positive effect and positive experience.Many factors could be the influence factor to well-being.Measures should be taken to improve Subjective well-being of type 2 diabetes patients.

Objective To establish experimental autoimmune cerebral spinal cord inflammation ( EAE) model rats, and observe the pathological changes and effect of oxymatrine on EAE model.Methods 30 rats were randomly divided into control group,EAE ( model group) group and oxymatrine group.The EAE symptom score was used to evaluate the rats after the model, and to observe the changes of its behavior.By HE staining and Kluver &Barrera myelin dyeing to observe the inflammation of the brain and spinal cord demyelinating changes.Results The animals in control group had no change in behavior and pathological.In model group, all animals occured behavioral changes, accompanied by varying degrees of demyelination and inflammatory infiltration of the brain and spinal cord.In oxymatrine group,6 rats did not appear EAE clinical manifestations and behavioral change, and the myelin structure was intact.Conclusion Oxymatrine can extend the incubation period experimental autoimmune encephalomyelitis in rats of the disease, relieve symptoms and protect nerve.

cholesterol 7α-hydroxylase gene ( CYP7A 1 ) plays a key role in the catabolism of cholesterol into bile acids. To investigate whether the A-204C polymorphism in CYP7A1 gene affects the gene expression,using luciferase as the reporter gene, four recombinants were constructed by inserting forward or reverse sequence with A or C allele at the polymorphism site into the promoter-less vector pGL3-basic. The constructs were then transfected into four cell lines and the luciferase activity of each expression vector was examined by dual luciferase reporter gene assay system. The results showed that activities of the forward sequence of both genotypes were higher than that of reverse sequence. Promoter activity of the recombinants with A allele was about one third lower than that with C allele. According to the analysis with TRANSFAC database, there may exist a Zic3 binding site when there is the C allele at -204. Our study indicates that the A-204 C polymorphism in CYP7A1 promoter region decreases its promoter activity and thus represses the gene expression, possibly due to the lack of a potential Zic3 binding site.

A 28-year-old female patient presented with indurated erythema and nodules on the right lower limb for 2 years,with mild itching and pain.Skin examination showed a well-circumscribed irregular dark red patch measuring about 10 cm × 5 cm in size on the extensor aspect of the right thigh.On the patch,there were scattered or densely distributed mung bean-to soybean-sized quasi-circular violaceous nodules with a smooth surface,which were hard on palpation.Subcutaneous nodules with medium hardness were found on palpation,and hyperpigmentation was observed on the surface of some nodules.Local skin temperature was increased,with tenderness on palpation.Histopathologically,mononuclear cells showed nodular or sheet-like distribution in the middle and upper dermis,some of which had pale-staining cytoplasm.Moreover,plenty of plasma cells were observed.Immunohistochemistry revealed that histiocytes were stained strongly positive for S100.The number of IgG4-positive plasma cells increased obviously,and was more than 50 per high-power field (× 200).The proportion of IgG4-positive plasma cells in IgG-positive plasma cells was 45％.Finally,the patient was diagnosed with cutaneous Rosai-Dorfman disease with increased IgG4-positive plasma cells.

OBJECTIVE: To analyze the rate of 235delC mutation in GJB2 gene in patients with idiopathic sudden hearing loss, and to explore its possible correlation with pathogenesis of idiopathic sudden hearing loss. METHOD: Two hundred and thirty-four patients with diagnosis of idiopathic sudden hearing loss in otolaryngology department were recruited as experimental group. Eighty people with normal hearing level were enrolled as control group. Their peripheral blood samples were obtained and genomic DNA was extracted. Using polymerase chain reaction, the coding region of GJB2 gene was amplified, and 235delC mutation is screened for in GJB2 gene by restriction endonuclease. At same time the clinical data of 234 patients was collected to analyze. RESULT: In 234 cases of idiopathic sudden hearing loss, 5 cases were found to have heterozygous 235delC mutation, none of them harbored homozygous 235delC mutation, the 235delC mutation rate was 2.1% (5/234). No 235delC mutation was found in control group. The rate of 235delC mutation in two group showed no statistically significant difference (P > 0.05). CONCLUSION This research shows that the rate of 235delC mutation in GJB2 is low in patients with idiopathic sudden hearing loss, and suggest that 235delC mutation possible has no correlation with idiopathic sudden hearing loss.

Objective To explore the factors related to vasovagal syncope (VVS) in children. Methods The clinical data of 125 children with conifrmed VVS were collected. According to the frequency of syncope during the ifve years from ifrst episode to the time of head-up tilt test, the children with 2 or 3 episodes of syncope were assigned into the low episode group, and the children with 4 or more episodes of syncope were assigned into the high episode group. The two groups were analyzed and compared. Results Among the 125 children, 84 children (67.2%) were in the low episode group and 41 children (32.8%) were in the high episode group. The single factor analysis showed that the age at head-up tilt test, onset of syncopal, causes of syncope, history of carsickness, and positive family history were associated with high attack frequency. The results of non-conditional logistic regression analysis showed that causes of syncope (OR?=?3.723, 95%CI:1.163-11.918, P?=?0.027), history of carsickness (OR?=?5.929, 95%CI:2.066-17.015, P?=?0.001), and positive family history (OR?=?6.794, 95%CI:2.006-23.013, P?=?0.002) were the independent risk factors of high attack frequency. Conclusions The causes of syncope (excluding persistent standing), history of carsickness, and positive family history have important clinical signiifcance in predicting high attack frequency of VVS in children.

Objective To lay the foundation for further exploration on parasitifer's defence reaction to pneumolysin through constructing ply gene-deletion strain of Streptococcus pneumoniae and researching on its virulence change. Methods A linker fragment with erm gene in middle and homologous upstream and downstream fragment of ply gene at both sides was prepared by long flanking homology-polymerase chain reaction(LFH-PCR). The linker fragment was transformed into Streptococcus pneumoniae. ply-deficient strain was then screened out from blood plate which contains erythromycin and identified by PCR. ply-deficient strain growth in vitro was observed and virulence change was observed through infecting mouse model. Results PCR results showed that ply gene was replaced completely by erm gene. The ply deficient strain was successfully constructed. The growth of single strain culture medium showed that ply genetic defect made no influence on bacterial's external growth. While in the mice nasal cavity infecting experiment, deficient strain enter into blood after 6 h from infecting which obviously slower than that did wild-type(2 h). And the number of bacteria at each point was much smaller than that of wild-type(P ＜0. 01 ). The mice peritonaeum infecting experiment showed that median lethal time of wild-type was 3 d, while that of deficient strain was 18 d(P＜0. 01). Conclusion It is a good way to completely substitute ply gene using LFH-PCR. ply deletion made no influence on baterial's growth in vitro, but it resulting in reduction of bacterial virulence in vivo.

This article reviews the research progress of intervention strategies for dysphagia after radiotherapy in patients with nasopharyngeal carcinoma, aiming to improve the prognosis of patients with nasopharyngeal carcinoma.

[Objective] To evaluate the clinical efficacy and safety of propranolol in treating infantile hemangiomas.[Methods] Ninety children with hemangioma collected from July 2010 to November 2011 were recruited in this study.Oral propranolol was given at a dose of 1.5-2.0 mg/kg per day,and the dose was adjusted according to the growth of body weight.Patients were revisited every month for the observation of appearance of hemangioma.The following parameters,including blood glucose,alanine transarninase,aspartate aminotransferase,urea nitrogen,creatinine,creatine kinase,heart rate,blood pressure,electrocardiogram and ultrasound image of hemangioma,were monitored before and after the administration of propranolol.[Results] A rapid halt in haemangioma proliferation was seen in 91.1％ (82/91) of the patients within 24-48 hours after the administration of popranolol.After 1-10 months of treatment,haemangioma shrunk by 0-25％ with a lightening of lesional color in 8.0％ (7/88) of the patients,by 26％-50％ with an obvious lightening of lesional color in 39.8％ (35/88),by 51％-75％ with a marked lightening of lesional color in 26.1％ (23/88),and 26.1％ (23/88)of the patients achieved a shrinkage of more than 75％ or fading of lesional color.The 7-8 months of treatment leaded to the best outcome,followed by 5-6 months,3-4 months,and 1-2 months,of treatrnent.No rebound was observed in patients who stopped the treatment at 10 months to l year and 4 months of age.Usually during early stage of the therapy,some of the patients suffered from reduced diastolic blood pressure,sleep disorder,loose stools,hypoglycemia,cold extremities,bronchial hyperreactivity,elevated alanine transaminase/aspartate aminotransferase or creatine kinase isoenzyme,most of which were tolerable and relieved with or without symptomatic treatment.[Conclusion]s Propranolol can suppress the growth and accelerate the regression of hemangiomas in proliferative phase,and also can promote the subsidence of hemangiomas in regressive phase.The side effects of propranolol are usually mild,but still need close monitoring.

Objective: To assess the effectiveness in optimizing resources and shortening critical children′s waiting time in pediatric emergency department (PED) with five-level pediatric emergency triage system (PETS). Methods: This retrospective study was conducted in the First Affiliated Hospital of Xiamen University after PETS was applied. The data of patients who visited the pediatric emergency department from January 2015 to December 2017 were collected and analyzed, including age, sex, diseases, visiting time, triage rate and destination. Results: A total of 375 985 patients were included, among whom males were 225 308 (59.9%) and females were 150 677 (40.1%), all younger than 14 years of age. The number of critical cases (level Ⅰ, level Ⅱ and level Ⅲ) was increased from 4 719 (3.7%) in 2015, 12 209 (10.2%) in 2016 to 16 188 (12.7%) in 2017. The number of non-critical patients (level Ⅴ) decreased year by year, as from 98 213 (76.8%) in 2015 to 75 210 (62.6%) in 2016 and 78 857 (61.7%) in 2017. The patients who classified as level Ⅰ or levelⅡaccording to the PETS were seen immediately by physician (n=1855, 0.5%). Overall, 119 738 patients (98.3%) who were classified as level Ⅲ or level Ⅳ could be seen by physician in a timely manner according to triage guidelines, while 2 112 patients (1.7%) could not. The mean waiting time was 9.09 min in level Ⅲ, 17.7 min in level Ⅳ, and 55.76 min in level Ⅴ patients, respectively. The critical cases admitted to the intensive care units were 175 (36.2%) in 2015, 350 (62.8%) in 2016 and 374 (66.2%) in 2017. The etiologies were respiratory diseases (73.3%), gastrointestinal diseases (15.8%) and infectious diseases (3.1%). Conclusion The application of PETS could optimize emergency resources and shorten the waiting time of critically ill children.
