Objective To analyze the etiology of diabetes ketoacidosis(DKA) in children with type 1 diabetes.Methods Totally 850 person-time of type 1 diabetes children in recent 20 years in our hospital were selected as studied subjects. Two hundred and twenty-five person-time of them were hospitalized because of DKA.Fifty-six cases (131 person-time) were due to recurrent DKA.These patients were classified into 2 groups according to onset time: group 1(diagnosed from 1982 to 1991) and group 2(diagnosed from 1992 to 2001).Results The analysis of recurrent DKA suggested that 71.8 % of them was due to infection, 20.4 % of them did not obey diabetic diet and 9.2 % of them discontinued insulin injection. The etiology of DKA showed no difference in two groups. The number of recurrent DKA in two groups was significantly different (P

Objective To observe the therapeutic effect of herbal decoction Kugan Yin for cystic hyperplasia of breast.Methods The 131 cases of cystic hyperplasia of breast in phlegm combining qi stagnation syndrome were randomized into treatment group(68 cases)which was treated by Kugan Yin and control group(63 cases)which was treated by Rupixiao Tablets(Tablets for dissolving breast nodules).The changes of symptoms and signs,level of serum sexual hormone and molybdenum target mammography analysis of two groups were observed for comparison.Results The total effective rate of treatment group was obviously better than that of con- trol group(P

Objective To compare the consistency of thrombelastography (TEG) and light transmittance aggregometry (LTA) in monitoring the antiplatelet therapy of the patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI),and observe the changes of mean platelet volume (MPV) of the patients treated with aspirin and clopidogrel after PCI.Methods A total of 177 patients undergoing PCI and the treatment of aspirin and clopidogrel in Peking University First Hospital during March 2014 and May 2015 were enrolled in the study.Their adenosine diphosphate (ADP) or arachidonic acid (AA) induced platelet inhibition rates determined by TEG,MPV before and after antiplatelet therapy,and the maximum platelet aggregation rates measured by LTA from 99 patients were retrospectively analyzed.Results There was no any correlation between the maximum aggregation rates measured by LTA and the platelet inhibition rates determined by TEG regardless of using ADP or AA as agonist (all P ＞ 0.05).The detection rates of clopidogrel hyporesponsiveness determined by LTA and TEG were 30.3％ and 45.5％,respectively,while those of aspirin hyporesponsiveness were 19.2％ and 31.3％,respectively.The detection rate of hyporesponsiveness determined by LTA was significant lower than that by TEG (P ＜ 0.05).The MPVs after antiplatelet therapy were significant lower than that before treatment (all P ＜ 0.01) regardless of clopidogrel hyporesponsive or sensitive and aspirin hyporesponsive or sensitive.The MPVs in clopidogrel hyporesponsive group before and after treatment were significantly lower than that in clopidogrel sensitive group (all P ＜ 0.05).The PLT counts in clopidogrel or aspirin hyporesponsive groups after treatment were significantly higher than that before treatment (all P ＜ 0.05).Conclusion There is poor correlation between LTA and TEG.It should be noted that the incidence rate of antiplatelet drug hyporesponsiveness is high in clinical practice.The MPVs of the patients significantly decrease after antiplatelet therapy.The patients with a significant increase of PLT after antiplatelet therapy are more likely to become drug hyporesponsiveness,while the patients with lower MPV are more likely to have clopidogrel hyporesponsiveness.

Objective To reveal the self-management status of patients with hypertension in community, and to analyze the influencing factors of self-management behavior so as to provide theoretical basis for the formation and maintenance of self-management. Methods With the method of stratified random cluster sampling, 559 patients with hypertension were selected from twelve communities in six urban districts of Wuhan completed the questionnaire survey to analyze the demographic characteristics, executive condition of self-management behavior and related psychological behavior with hypertension patients. Results The average age was (61.2 ± 8.4) years. The rate of measuring blood pressure regularly was 38.39%, rate of regular medication was 63.83%, rate of low salt diet was 37.72%, and the rate of regular exercise was 50.45%. The score of self-management was 0.60 ± 0.21. Self efficacy was the influencing factor of self-management score (β=0.042 1,P<0.01). Conclusion Self assessed efficacy is closely related to self-management. Intervention should be guided by psychological behavior theory, and emphasized on psychological aspect.

Objective To study the effects of iodine deficiency and hypothyroidism on protein expression of extracellular signal-regulate kinase(ERK1/2) in the cerebellum of rots. Methods Twenty-eight healthy Wistar rots, female, 60 days old, were randomly divided according to their body weight into control group, iodine deficient group and hypothyroidism groups. Hypothyroidism groups in accordance with drinking water containing propylthiouracil(PTU) were divided into doses of 5 mg/L and 15 mg/L groups, 7 rats in each group. Rats after pregnancy, iodine deficient rats were administered with iodine-deficient diet and hypothyroid rats were administered with PTU in drinking water. Pup's cerebellum in each group were weighed on day 14,21,28 and 42. Cerebellum tissue was observed for cerebellar morphology using silver staining and detected for ERK1/2 protein using immunohistochemistry on day 7,14,21,28 and 42. Results On day 14,21,28 and 42, cerebellum weight of pups from iodine-deficient[(0.0945±0.0233), (0.1347±0.0046), (0.1542±0.0094), (0.1949±0.0048)g]were significantly lighter than control[(0.1856±0.0123), (0.2049±0.0098), (0.2268±0.0065), (0.2606±0.0086)g, all P < 0.05]and hypothyroidism groups [for 5 mg/L group: (0.1741±0.0172), (0.1927±0.0103), (0.2181±0.0064), (0.2583±0.0054)g, all P<0.05; for 15 mg/L group: (0.1604±0.0083), (0.1682±0.0103), (0.1996±0.0073) and (0.2579±0.0067)g, all P< 0.05]the difference had statistical significance(F=6.325,8.870, 16.191 and 21.574, all P<0.05). Compared to the controls on day 7, iodine-deficient group didn't have clear layers; on day 21, disappearance of external granule cells from iodine-deficient and 15 mg/L groups was delayed, still two or three layer external granule cells remained; on day 28 and 42, molecular layer from 5, 15 mg/L and iodine-deficient groups and became thinner. Immunohistochemistry showed that on day 7, there was no statistical difference of integrated optical density average of ERK1/2, in all the groups(F=1.102, P>0.05); on day 14,21,28 and 42, integrated optical density average of ERK1/2 in iodine-deficient group[(7.3245±0.5070), (8.3606±1.0683), (9.1217±1.0402), (12.1587±0.7581), all P<0.01]and hypothyroidism groups [for 5 mg/L group: (11.4307±1.5200), (14.919±0.8497), (16.0082±1.1130), (15.7721±0.8293), all P< 0.01; for 15 mg/L group: (7.8538±0.9775), (11.2461±0.8138),(12.78±1.3783), (13.0871±1.1450), all P < 0.01]was significantly lower than those of controls [(16.2831±0.5143), (20.2653±0.9551), (22.7485±1.0267), (22.1725±0.9939), all P < 0.01], the difference having a statistical signifieance(F=16.131,13.543,26.953,41.583, all P<0.01). Conclusions Iodine deficiency and hypothyroidism during critical periods of brain development may change eerebellar morphology and down regulate the protein expression of ERK1/2, which may result in damage of cerebellum development.

Objective To investigate the effect of kinesio taping on upper crossed syndrome (UCS). Methods From December, 2016 to March, 2017, 52 patients with UCS were randomly divided into control group (n=26) and observation group (n=26). The control group re-ceived exercise therapy, and the observation group received kinesio taping in addition, for four weeks. They were assessed with Visual Ana-logue Scale (VAS), forward head angle (FHA) and forward shoulder angle (FSA). Results There was no significant difference in the score of VAS, FHA and FSA between two groups before treatment (P>0.05). After treatment, the scores of VAS, FHA and FSA significantly de-creased (t>2.804, P<0.05), and they were less in the observation group than in the control group (t>2.632, P<0.05). Conclusion Exercise therapy could relieve pain and correct abnormal posture of UCS, which is more effective combined with kinesio taping.

Objective:To investigate the wear resistance of four low-shrinkage commercial composite resins and two traditional composite resins in vitro and discuss the relative influencing factors, and to illustrate the inner relationship of the wear resistance of resins and material composition.Methods:Four low-shrinkage commercial composite resins including CLEARFIL MAJESTY Posterior(CMP), Filtek LS(LS), Admira(AD), Kalore(KA) and two traditional composite resins including Filtek Z350XT (Z350), Solitaire2(S2) were chosen.The bar-shaped specimens were fabricated and mounted in a UMT-2 wear testing machine and abraded with the two-body media (distilled water) with a Si3N4 ball as antagonist.The maximum wear depth was determined after 14 400 cycles.The friction coefficient was determined during the test.The worn surfaces were examined with SEM.Results:CMP showed the lowest maximum wear depth and KA presented the highest maximum wear depth.The maximum wear depth ranked as follows: CMP

To confirm the etiology of a dead case for a 6 year-old female Ailurus fulgens,one strain of the predominant bacteria from pathologic tissues(heart,liver,spleen,lung and other samples) of the dead Ailurus fulgens were examined and isolated.The isolate was named R1 and no other bacteria were isolated.The bacterial etiological examination(morphological characteristics,biochemical characteristics and 16S rDNA gene detection)of R1 showed that it was identifed as K.peneumoniae.Artificial infection to mice about R1 was also conducted in this study.R1 had strong pathogenicity to mice and the LD50 is 6.5 × 104 CFU/mL.Moreover,the clinical and pathological features of the dead mice were consistent with that of the Ailurus fulgens.To find effective therapeutic drugs of curing other Ailurus fulgens,antibiotic sensitivity test of R1 was conducted,and the results revealed that R1 was highly sensitive to cefotaxime et al,moderately sensitive to amikacin and resistant to penicillin.These data showed that K.peneumoniae was bacterial pathogen leading to death of the Ailurus fulgens and it had strong resistance to penicillins,macrolides and virginiamycin and it had broad drug resistance spectrum.However,R1 is sensitive to cephalosporins and aminoglycoside antibiotics.

Objective To evaluate the efficacy of systemic glucocorticoids and intravenous immunoglobulin (IVIG)for the treatment of toxic epidermal necrolysis (TEN). Methods Clinical data on TEN inpatients treated with systemic glucocorticoids alone or in combination with IVIG were collected from the Department of Dermatology, First Affiliated Hospital of Nanjing Medical University from January 2006 to December 2012. Therapeutic outcomes were evaluated in these patients. Statistical analysis was carried out by using a multiple linear regression analysis, binary logistic regression analysis and Cox regression analysis with the SPSS 16.0 software. Results A total of 48 inpatients with TEN were included in this study. Multiple linear regression analysis showed that the maximum daily dose of glucocorticoids for disease control was decreased gradually over years (β=-0.461, P=0.004). However, binary logistic regression analysis revealed no obvious changes in the frequency of administration of IVIG over years. Cox regression analysis showed that both hospitalization duration (RR=0.351, 95.0%CI:0.150-0.825)and the time required for the control of skin lesions (RR=0.492, 95.0%CI:0.245-0.986)decreased with the increase in the frequency of IVIG administration. In addition, with the increase in the maximum daily dose of glucocorticoids for disease control, the time required for the control of skin lesions was also shortened (RR=0.997, 95.0%CI:0.994 -1.000), while no obvious changes were observed in hospitalization duration. Conclusions IVIG shows superiority in controlling lesions, reducing complications and improving the prognosis of TEN. Compared with systemic glucocorticoids, IVIG shows better therapeutic efficacy and less adverse effects, and may be preferentially selected.
