Objective To find out the associated effect of intrauterine infection and interuterine asphyxia to fetal rat′s brain damage,cell apoptosis,and expression of glial fibrillary acidic protein(GFAP).Methods Pregnant rats of gestation 18 days were randomly divided into four groups:1.NS plus sham operation,2.intrauterine infection,3.intrauterine asphyxia,4.intrauterine infection plus intrauterine asphyxia.The fetal rats′ brains were taken out 72 h after different disposal and given HE coloration,immunohistochemistry of TUNEL and GFAP,respectively.Results The level of brain cell edema and tissue disorganization of group intrauterine infection plus intrauterine asphyxia were more serious than those of group intrauterine infection or group intrauterine asphyxia.TUNEL and GFAP had the same results:The number of positive cells in group intrauterine infection plus intrauterine asphyxia more than that in group intrauterine infection,and which in group intrauterine asphyxia more than that in group NS plus sham operation.There was significant difference between the first three groups and the group NS plus sham operation(P=0).There was also significant difference between group intrauterine infection plus intrauterine asphyxia and group intrauterine infection or group intrauterine asphyxia(P=0).Conclusions Both intrauterine infection and intrauterine asphyxia may induce premature rat brain damage,the association of intrauterine infection and intrauterine asphyxia may aggravate the degree of fetal rat brain damage,also increase the number of apoptosis cell and the expression of GFAP.

Objective:To investigate the effect of Na + , K + -ATPase on the increase of cytosolic Ca 2+ level induced by hypoxia in rat cortical neurons. Methods: Using confocal laser scanning microscope and video based motion edge detection system, we measured the intracellular Ca 2+ concentration (\ i ) and Na + concentration (\ i ) in cortical neurons exposed to hypoxia for different time periods and at presence of different concentrations of dihydroouabain (DHO, an inhibitor of Na + , K + -ATPase). We also observed the effect of Na + , K + -ATPase on the increase of cytosolic Ca 2+ level induced by hypoxia in rat cortical neurons. Results: DHO (10 -9 -10 -3 mol/L) dose-dependently and hypoxia(4-20 min) time-dependently increased the levels of \ i and \ i in cultured cortical neurons. \ i and \ i increased significantly 4 min after cortical neurons were exposed to hypoxia, and addition of DHO (10 -3 mol/L) further increased their concentrations. While 15 min after hypoxia exposure, different concentrations of DHO did not further increase \ i and \ i. We also found that hypoxia exposure did not enhance DHO pretreatment-induced \ i increase. Conclusion: Inhibition of Na + , K + -ATPase activity is one of the mechanisms responsible for hypoxia-induced elevation of \ i in cortical neurons.

Objective To investigate the influence of preterm premature rupture of membranes (PPROM) on neurological development of preterm infants.Methods The preterm infants were classified into 2 groups( PPROM group and control group).The neonatal behavioral neurological assessment (NBNA) and CDCC of infants in two groups were measured and compared after retrieved:gestational age 40 weeks,3 months and 6 months.Results Psycho-moter developmental index(PDI) of PPROM group after retrieved gestational age 3,6 months was significantly lower than that of control group(Pa

OBJECTIVE:To understand the proportion of university faculty suffering from hypertension,and the regularity,ratio-nality and affordability of antihypertensive drugs under closed medical environment. METHODS:Empirical research and research methods were adopted to collect indicators during 2011-2014,such as average daily wage in Wuhan,the total number of staff in Wuhan University,the number of staff with hypertension,antihypertensive drugs amount/DDDs ranking ratio,affordability ratio,relative av-erage affordability, etc. The rationality and affordability of antihypertensive drug prices were evaluated. RESULTS:During 2011-2014,the prevalence rate of hypertension in the staff were about 23%,and the proportion increased year by year;the annual in-crease of antihypertensive drug amount was larger than that of the number of patients;the type of antihypertensive drugs with affordabil-ity ratio>1 in 4 years was ARB varieties,and affordability ratio of other drugs was less than 1. CONCLUSIONS:More than half of drugs is high in price,that result in heavy burden of patients receiving ARB;on the whole,antihypertensive drugs are affordable of the teaching staff of Wuhan University.

Objective To investigate the sniff nasal inspiratory pressure (SNIP) of Chinese boys. Methods 299 healthy boys aged 5-12 years were measured with SNIP. Their height, weight, and age were recorded. Results The SNIP averaged (76.9±22.6) cmH2O, and was (59.1±14.2) cmH2O, (76.9±19.5) cmH2O, (85.3±23.5) cmH2O and (83.0±22.6) cmH2O in the boys of 5-6 years old, 7-8 years old, 9-10 years old and 11-12 years old, respectively. It was significantly different among boys of 5-6 years old, 7-8 years old and 9-10 years old (P<0.05), but no significant difference between 9-10 years old and 11-12 years old (P=0.55). Regression analysis indicated significant relations of SNIP with age, height, weight and Body Mass Index (P<0.01). Conclusion The SNIP of Chinese healthy boys are different from abroad. It is necessary to establish the Chinese children SNIP reference range.

Objective To screen the clinical factors affecting the malignant probability of solitary pulmonary nodule (SPN) with univariate and multivariate Logistic regression analysis,and to establish a clinical prediction model,evaluate its test effectiveness in the differential diagnosis in SPN.Methods A retrospective cohort study included 182 patients with diagnosis of SPN (group A).Clinical data included gender,age,smoking history,quitting smoking,history of tumor,serum carcinoembryonic antigen (CEA),location,diameter,density,vacuole sign,cavity,airbronchogram,calcifcation,lobulation,spiculate sign,spiculation,pleural indentation sign,vascular convergence sign,enhanced CT value,the maximum standard uptake value (SUV~x) of positron-emission tomography (PET),pathological diagnosis were collected.The independent predictors of malignancy were estimated with univariate and multivariate analysis,then the clinical prediction model to identify malignant was established.Other 45 SPN patients (group B) were used to tested value of the model.Results Univariate analysis showed that gender,age,no lower lobe location,diameter,density,airbronchogram,calcification,lobulation,spiculation,pleural indentation sign,enhanced CT value ≥ 15 HU,SUVm,≥ 2.5 of PET significantly affected judgment of SPN of benign or maligant (P ＜ 0.05).Multivariate analysis revealed that female,age,lobulation,short spiculation,pleural indentation sign was the independent predictors of malignancy in patient with SPN,solid nodule suggested benign.The clinical prediction model to identify malignant was established:P =ex/ (1 + ex),x =-3.399 +1.382 × gender + 0.056 × age + 1.377 × lobulation + 1.498 × spiculation-2.096 × solid + 1.005 × pleural indentation sign,e was natural logarithm.P =0.663 was as cut-off point,group B was used to test value of the model:the sensitivity was 86.5％,the specificity was 62.5％,the positive predictive value was 91.4％,the negative predictive value was 50.0％,the accuracy was 82.2％.Conclusions As for SPN,female,age,lobulation,short spiculation and pleural indentation sign is the independent predictor of malignancy in patient with SPN,solid nodule suggests benign.The prediction model is sufficient to estimate the malignancy of patient with SPN.
