Objective To investigate the relationship between children history of asthma and family history of asthma.Methods Three thousand and five hundred outpatients of asthma children were selected as investigation subjects.Family history of asthma was investigated in the form of questionnaire,and analyzed them from whether or not having family history of asthma,the first and second degree relative having family history of asthma.Results There was no family history of asthma in 1 659 cases(47.4%) and while 1 841 cases had family history of asthma(52.6%).The children who had family history of asthma were slightly more than those who had no family history of asthma.Among the 1 841 cases with family history of asthma,the first degree relatives with family history of asthma were more than those second degree relatives with fa-mily history of asthma.The incidence rate of relatives with family history of asthma on mother′s side was 59.9%,and the incidence rate of the father′s relatives was 40.1%.The incidence rate of mother′s relatives was higher than that of father′s relatives(P

Objective To explore the occurrence of diaphragmatic muscle fatigue(DMF) in children with pneumonia and its relationship with respiratory failure.Methods One hundred and twenty-six cases of pneumonia(pneumonia group) and 60 healthy children(healthy control group) were selected,and 2K-V1 type intelligence electric impedance respirograph was used to measure diaphragmatic function of the children in both groups to find if the ribcage-abdomen motion was synchronic and to calculate M levels.The abdomen impedance values as X-axis were calculated,which were regarded,and the chest impedance values as Y-axis were calcaulated,which described two-dimensional chart of ribcage-abdomen motion curve and the ? angle which was between connection of maximum X value to the smallest X value and the X-axis were calculated.According to the changes of chest-abdominal curve in one-dimensional chart and the changes of M value and ? angle,the degree of the diaphragmatic muscle fatigue was judged.Results There were 98 cases of DMF in the 126 children with pneumonia,and 68 cases of which were type Ⅰ DMF,and 30 cases were type Ⅱ DMF.One-dimensional chart showed contradictory chest-abdominal respiratory motional curve,and two-dimensional chart moved in a clockwise direction.M value was(46.1?8.4)%,? angle was(136.7?12.0) degrees in children with type Ⅰ DMF;One-dimensional chart showed that the peak value of chest-abdominal respiratory motional curve dislocates,and two-dimensional chart moved in a counter-clockwise direction.M value was(17.2 ? 3.2)%,? angle was(48.2 ? 9.5) degrees in children with type Ⅱ DMF;the control group had M value(4.3 ? 1.0)%,? angle was(31.7 ? 5.2) degree.There were significant differences in M value and ? angle between type Ⅰ DMF children,type Ⅱ DMF children and healthy children(Pa

Objective To explore the expressions of transforming growth factor(TGF)-?1 and connective tissue growth factor(CTGF) in viral myocarditis(VM) and the intervention effect of valsarta on them.Methods Fifty-four male Balb/c mice were randomly divided into 3 groups:control group,treatment group and model group.Model group and treatment group established VM model by intraperitoned injecting 0.1 ml CVB3.They were killed on days 7,14 and 28,respectively.Histological cross sections of heart were stained with hematoxylin-eosin and myocardial histopathplogic scores were counted under optical microscope.The expressions of typeⅠand Ⅲ myocardial collagen,TGF-?1 and CTGF were examined by immunohistochemical method and analyzed by using SPSS 11.5 software.Results Compared with control group,histopathplogic scores,the expressions of type Ⅰand Ⅲ myocardial collagen,TGF-?1 and CTGF increased markedly in model group (Pa

AIM:To evaluate the efficacy and safety of Sub-tenon's anesthesia for compound trabeculectomy with high intraocular pressure.
METHODS: Forty - six eyes ( 46 cases ) of primary glaucoma received compound trabeculectomy under Sub-tenon's anesthesia, whose preoperative intraocular pressure were higher than normal after 24 to 48h of combined medication. Both efficacy and complication of the anesthesia were studied.
RESULTS: One minute after anesthetic injection, all cases were able to achieve the effect of analgesia and eye brake. During the operation, 0 level of anesthesia effect included 35 eyes ( 76%) , 1 level of anesthesia effect included 10 eyes ( 22%) , 2 level of anesthesia effect included 1 eye(2%). Only 1 case of these patients needed to add the surface anesthetic once, and other cases were successfully operatedunder Sub-tenon's anesthesia. The total effective rate was 98%. No anesthesia complications occurred in all cases.
CONCLUSION: Sub - Tenon's anesthesia is safe, effective, simple and quick for compound trabeculectomy with high intraocular pressure.

Objective To explore the effects of PSE on hemodynamics and Liver function in LCPH. Methods 30 patients with LCPH are treated by PSE. The hemodynamics changes of patients with LCPH are evaluated with color Doppler diasonograph. The changes of main clinical features which is related to LCPH , serum ALT and albumn were investigated . Results The hemodynamics indexs of LCPH are all changed significantly (P0. 05) between four and two weeks after PSE. But the main symptoms, signs of LCPH and liver function are improved after PSE . Conclutions PSE plays an important role in hemdynamics and liver function of LCPH. After PSE, Portal hypertension decreases effectively and liver function is improved.

Objective:To study the function of tumor necrosis factor r eceptor-associated factor 6(TRAF6) in the development of rat dental germ. Methods:After specimen preparation of every stage of rat developing d ental germs, immunohistochemical staining of TRAF6 was carried out. Resu lts:Positive expression of TRAF 6 was observed in thickening stage of de ntal lamina, peripheral dental lamina of bud stage, outer and inner enamal epith elium, stellate reticulum,dental papilla cells and dentinoblasts in early bell s tage, ameloblasts, dentinoblast,intermediate layer, stellate reticulum and denta l papilla cells in late bell stage, and dentinoblasts and ameloblasts in the ger m 7 days after birth. Conclusions:TRAF6 may be a signal transduc tion factor which modulates the proliferation and differentiation of developing epithelial and mesenchymal cells in the development of the dental germ.
