Objective To evaluate the value of peripheral blood neutrophil CD_(64) level for early diagnosis of neonatal septicemia.Methods Thirty-six cases of neonatal septicemia were recruited into the study according to diagnostic criteria for neonatal septicemia:white blood cell count,C-reactive protein(CRP),platelet count,micro-erythrocyte sedimentatio rate(mESR) and blood culture;26 cases of hospitalized neonates with non-infectious diseases were enrolled as controls.The level of peripheral blood neutrophil CD_(64) was measured by flow cytometry.Results The level of peripheral blood neutrophil CD_(64) in septicemia patients were(60.37?22.70)mean fluorescence intensity(MFI),which were significantly higher than that of control group(23.14?5.10)MFI(P

Objective To explore the puberty and height development in childern with congenital adrenal hyperplasia(CAH) due to 21-hydroxylase deficiency(21-OHD) with the simple virilizing(SV) form.Methods Patients of SV 21-OHD,diagnosed and treated in Tianjin Children's Hospital from Jan.1970 to Jan.2008,were treated with cortisone acetate or hydrocortisone after diagnosed,and blood investigations were performed as part of monitoring,and dosages were adjusted accordingly to obtain normal growth velocity and slow bone age(BA) development.Gonadotropin-releasing hormone agonist(Gn-RHa) was given after the appearance of central precocious puberty(CPP).Forty-one patients(18 females,23 males) had achieved final height before Dec.31st 2008,and their puberty and height development were analyzed in this longitudinal study by contrast the ages and statures of obtaining final height(FH),chronological age(CA) and BA of G2/B2 stage,duration from G2/B2 stage to obtain FH and stature development of different gender during this period and the influences of compliancy on the ages and statures of obtaining FH were contrasted.Results With regarding to the age of testicular volume ≥4 mL,78.26% boys were before 9 years old.As far as the age of breast development was concerned,38.89% girls were before 8 year old and 66.67% menarche occurred before 10 year old.The differences between the duration and stature development of the period from the state of G2/B2 to skeletal maturation of different gender were significant (Pa

Objective To analyze rate of and reasons for not undertaking insulin pump therapy in children with type 1 diabetes(T1DM) and explore potential countermeasures.Methods Two hundred and seventy-eight persons of T1DM,diagnosed in Tianjin Children′s Hospital from Jan.2000 to Dec.2008,were assigned to fill in a questionnaire on T1DM and insulin pump therapy.Reasons for different compliances were analyzed and strategies were explored.Results Eighty-five point twenty-five percent of the children(237 persons) undertook the therapy and 14.75%(41 persons) refused.In the group of younger than 3 years,58.33%(21 persons)accepted the therapy,while in the group of older than 3 years,89.26%(216 persons) undertook it,consequently there was statistically significant difference(?2=23.83,P

Objective Aliginic sodium diester(ASD) liposome was prepared and its aggregation stability was evaluated.Methods ASD liposome was made by reverse phase evaporating method from egg yolk lecithin,compared with blank liposome,the size distributions and mean particle diameters of ASD liposome and blank liposome were measured respectively before and after 40 hours heating under 37℃.Results Under the condition of n(PC)∶n(CHOL) = 1∶1,the mean size diameter of ASD liposome was 4.24?m.The mean size diameter of ASD liposome changed only 0.26?m after cultivation,however,the value of blank liposome was 1.35?m.Conclusion ASD loaded in the liposome enhanced the physical stability of the liposome.

Sjögren's syndrome is a chronic autoimmune disease with unclear etiology. From the point of etiology, Chinese medicine (CM) theory holds that pathological products like dry toxin, blood stasis are produced in the pathological process. They are both pathologic results and pathogenic factors for its further development. So pathological products are also named as second pathogenic factors. In this article, the concept of second pathogenic factors was sorted and defined. Main second pathogenic factors of Sjögren's syndrome were pinpointed, and their modern medical bases were analyzed. Authors came to a conclusion that clearing away second pathogenic factors is a key point in treating Sjögren's syndrome.

BACKGROUND:The condyle is one of important areas of lower mandible growth, and has growth remodeling capacity lifetime. The in vivo functional research fails to obtain satisfactory outcome due to the complexity of physiological environment, nondirectiveness of stimulating factor transduction, and difficulty to control experimental conditions. Further studies wil explore the effect of stress on condyle chondrocytes in vitro.
OBJECTIVE:To observe the effect of cyclic stress on the proliferation of rabbit condyle chondrocytes cultured in vitro.
METHODS:Rabbit condyle chondrocytes were separated and cultured in vitro. Passage 3 chondrocytes were subject to cyclic tensile stress (10%surface elongation, 6 cycles/min) for 1, 6, 12, 24 hours. While those cells without stress served as the control group. The cellcycle changes were detected with flow cytometry analysis, and the cellproliferation were analyzed by MTT assay.
RESULTS AND CONCLUSION:The flow cytometry analysis showed that S-phase promoting factor exhibited significant differences at 6 and 12 hours compared with control group, and got the maximum value at 24 hours (P<0.01). MTT assay results showed that the cells proliferation at 6 and 12 hours exhibited significant differences compared with the control group, and got the maximum value at 24 hours (P<0.01). The cyclic stress can obviously promote the proliferation of condyle chondrocytes, and the stimulative effect can be sustained 24 hours.

Objective To study the clinical application of the peak expiratory flow rate( PEFR) in children with asthma.Methods The PEFRs of 43 cases of asthma at the acute stage were measured to guide the clinical grading and therapy by the optimum individual PEFR of the patients at the remission stage, and the descending rate and warning value of individual PEFR were determined to investigate the relationship between the individual PEFR descending rate and the asthma attack conditions in the standard and nonstandard monitoring groups.Results At the asthma attack stage, the clinical symptoms became severe with PEFR declining; at the remission stage, the preventive application of drugs was based on the changes of the individual PEEF descending rate . The case number and frequency of asthma attack and the cases subjected to moderate or severe attacks in the standard group were 15 %,23.5 % and 25 % respectively; while those in the nonstandard group were 43.5 %, 75.5 % and 76.9 % respectively, which showed a significant difference( P

AIM: To assess the relative agreement of GAT and NCT in IOP measurement by comparing the differences between Goldmann applanation tonometer (GAT) and non-contact tonometer (NCT) in intraocular pressure (IOP) detection.METHODS: IOP of 529 eyes of 265 volunteers were measured with both NCT and GAT, respectively.RESULTS: The measurement results of NCT were lower than that of GAT, there was significant difference between the IOP measured with NCT and GAT (19.13 vs23.43, t=22.644, P＜0.05). With the increasing of IOP values, the difference magnitude was greater, especially in IOP group that was more than 30mmHg, but the correlation coefficient became lower.CONCLUSION: The measurement results with NCT are lower than that of GAT. When the IOP with the NCT is in borderline value, it need be corrected with GAT, in order to discover the pathologically elevated IOP and avoid the misdiagnosis and mistreatment of glaucoma.
