Objective To explore the changes of plasma brain natriuretic peptide(BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)of sepsis combined with myocardial injury in newborns.Methods According to neonatal sepsis treatment program,45 cases of sepsis newborns in NICU of the Second Hospital in Lanzhou University from Jul.2007 to Jun.2008 were collected.According to the myocardial injury diagnostic criteria,45 cases neonatal sepsis were divided into myocardial injury group(n=22) and non-myocardial injury group(n=23).Myocardial injury group was also divided into congenital heart disease group and non-congenital heart disease group accor-ding to echocardiography.At the same time,30 healthy newborns were collected as healthy control group.Every newborns were tested the level of plasma BNP,NT-proBNP,creatine kinase-MB(CK-MB) and cardiac-troponin I (cTnI).Results There were significant difference between myocardial injury group,non-myocardial injury group and healthy control group in the levels of plasma BNP,NT-proBNP,CK-MB and cTnI,those in congenital heart disease group were higher than those in non-myocardial injury group and the healthy control group(Pa0.05).Conclusions BNP and NT-proBNP can be early used to diagnose myocardial injury and heart failure of neonatal sepsis associated with CK-MB and cTnI.In NICU,infants with sepsis should normally test BNP and NT-proBNP in order to early diagnose myocardial injury of neonatal sepsis.

12-18 years old).In each age group,children were classified according to their genders.Diffusion tensor imaging(DTI)was performed in all the children's heads.Then the angles formed by splenium corporis callosi and occipital forceps were measured in fractional anisotropy maps.All the data were analyzed statistically.Results 1.The females in infant group had the larger angles formed by splenium corporis callosi and occipital forceps.With the age increasing,the average values of angles tended to decrease gradually.But in some age groups,the average values in some cases tended to increase before it decreased.2.A statistically significant sex difference was found in infant group.In young child group,pre-school age group and adolescence group,such difference was found in angles formed by occipital forceps.Only in young child group,difference in the maximum angles of splenium corporis callosi was found.3.There was a significant difference between age groups in the angles formed by sides of occipital forceps and the minimum angles of splenium corporis callosi through one-way analysis of variance.4.The angles of occipital forceps and the minimum angles of splenium corporis callosi both had a negative correlation with ages.They both had a linear regression to ages.But,there was no correlation between the maximum angles of splenium corporis callosi and ages.Conclusions Sex differences might exist in the angles formed by both sides of occipital forceps and splenium corporis callosi.The angles formed by sides of occipital forceps and parts of angles of splenium corporis callosi might decrease when the age increases.Diffusion-weighted technology can be used to study the age and sex difference in angles formed by splenium corporis callosi and occipital forceps in children.

A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

In 1999, the nomenclature and case definitions for neuropsychiatric lupus syndromes were published by American College of Rheumatology (ACR), and the cognition of neuropsychiatric damage of systemic lupus erythematosus (SLE) was gradually unified and standardized. Lupus headache is an intractable problem in SLE, especially in SLE patients complicated with multiple organ injury. In general, vascular headache is common in most SLE patients, and a small number of SLE patients complicated with nervous headache are found in clinic. Moreover, its pathophysiological mechanism is far from being understood. Although early diagnosis is essential for good outcomes, the diagnosis method is rather confused in the world. There still exist some limitations in the proposal of clinical classification of headache from ACR and International Headache Society (IHS), and the proposal does not mention the classification of headache related to psychiatric damage. Current therapeutic regimens are almost exclusively based on empirical evidence. Treatment approaches include symptomatic treatment, immunosuppressive, anticoagulant and anti-aggregant therapies. It provides enormous and hopeful space in research of combined therapy strategy, especially in the field of traditional Chinese medicine. The authors discussed the relationship between lupus headache and headache due to internal injury in the view of integrated traditional Chinese and Western medicine, and suggested that the treatment strategy for lupus headache should be made in argument with the headache due to internal injury. Syndrome differentiation treatment according to deficiency in the root and excess in the branch and the therapy for activating blood to dredge collaterals maybe have great advantages in treatment of the headache in SLE.

Objective To observe and analyze the MRI manifestations of Klippel-Trenaunay syndrome(KTS).Methods Thirty-one cases with diagnosed KTS underwent MRI on a 1.5 T MR system. MRI,MR venography(MRV),MR angiography(MRA)and X-ray venography(XRV)were performed.The pathological changes of the limbs and their veins were observed.Results MRI found soft tissue hemangiomas in 12 cases,soft tissue swelling of the extremities in 27 cases,superficial varicosities in 21 cases,and malformation of the veins in 27 cases.In twenty patients who underwent both MRV and XRV, superficial varicosities in 17 cases and persistent sciatic veins in 11 cases were found with both techniques. The increase of tributary veins was found in 10 cases with XRV,while found in 15 cases with MRV.The erratic venous course was found in 4 cases with MRV.The abnormalities of deep veins were found in 8 cases with MRV,while found in 7 cases with XRV.Conclusion MRI is an efficient and reliable imaging method for diagnosis of KTS.

ObjectiveTo evaluate the relationship between the proliferation of parathyroid cell in rabbit with primary hyperparathyroidism (PHPT) and the bone mineral density (BMD). MethodsEighty adult Chinese rabbits were randomly and equally divided into two groups. The contrast group was fed with normal diet ( Ca ∶ P, 1.0 ∶ 0. 7 ) and the experimental group was fed with high phosphate diet ( Ca ∶ P,1.0∶7.0) to establish the animal model of PHPT. At 3, 4, 5, and 6 months after the diet, bone mineral density of the rabbits was measured by the quantity CT (QCT). Then, the parathyroid and bone of the rabbits were removed for pathological examination. The number of parathyroid cell in PHPT was calculated.Proliferation was determined by immunohistochemistry of proliferation cell nuclear antigen ( PCNA ) and Bcl-2. The t test and Logistic regression was used to analyze the difference of data of two groups. ResultThe number of parathyroid cell in PHPT group was 1.61 times than that in the contrast group[ (673 ± 151 ) HP,(418 ± 25 ) HP,P ＜0. 01]. The rate of PCNA positive-cell was significantly increased in PHPT group than that in contrast group [(50.52 ± 11.62)％o, (26.70 ± 2. 78 )％, P ＜ 0.01], and so was Bcl-2[ (460. 37 ± 190. 05 )‰, (67. 02 ±:4. 38 )％‰,P ＜0. 05]. The value of BMD was significantly decreased in PHPT group than that in contrast group [ ( 152. 5 ± 34. 3 ), ( 188.6 ± 12. 2 ) g/cm3, P ＜ 0. 05]. There was a negative correlation between BMD and PCNA (r ＝ -0. 749, P ＜ 0. 05 ) and between BMD and Bcl-2 (r ＝-0.800, P ＜ 0. 05 ) in PHPT group. ConclusionThe BMD of PHPT is related to the parathyroid cells proliferation which provide a reliable method for early diagnosis of PHPT.

Objective To explore the diagnostic merits of the average apparent diffusion coefficient(ADCav) for leukoencephalopathy in neonates and children.Methods One hundred and fifty-six neonates and children with central nervous system signs or symptoms were classified into 6 groups according to their ages(1 d-0.05).Contrast to the normal,the ADCav of leukoencephalopathy in neonates and children decreased.With increasing age,there showed a linear downtrend in each group.Conclusions The ADCav rises in neonates and children with leukoencephalopathy.The ADCav variation precedes changes in routine MRI.

Objective To compare the efficacy of elective nodal prophylactic irradiation ( ENI) and involved?field irradiation ( IFI) in radical radiotherapy for early?stage esophageal cancer and to determine the appropriate irradiation range for early?stage esophageal cancer. Methods The clinical data of 121 patients with early?stage esophageal cancer receiving radical radiotherapy in our hospital from January 2006 to December 2011 were collected and respectively analyzed. Sixty?one patients received ENI, and the other 60 patients received IFI. The Kaplan?Meier method was used to calculate local control ( LC) and overall survival ( OS) rates;the log?rank test was used for survival difference analysis and univariate prognostic analysis;the Cox regression model was used for multivariate prognostic analysis. Results The 1?, 3?, and 5?year LC rates in ENI group and IFI group were 81. 1%, 60. 1%, and 57. 5% vs. 64. 5%, 43. 9%, and 27. 2%, respectively ( P=0. 003 ) . The 1?, 3?, and 5?year OS rates in ENI group and IFI group were 86. 9%, 56. 8%, and 34. 8% vs. 86. 7%, 34. 3%, and 19. 1%, respectively ( P=0. 019) . The 1?, 3?,and 5?year overall failure rates in ENI group and IFI group were 22. 3%, 53. 8%, and 63. 2% vs. 43. 3%, 65. 8%, and 78. 8%, respectively ( P=0. 023) . Multivariate analysis showed that irradiation range was the influencing factor for LC and OS. Conclusions As for the radical radiotherapy for early?stage esophageal cancer, ENI can significantly increase LC and reduce locoregional failure, and therefore improve long?term OS.

Objective To compare the failure pattern between esophageal cancer patients receiving definitive elective nodal irradiation (ENI) and involved-field irradiation (IFI) and to investigate the reasons and influential factors for locoregional recurrence and metastasis.Methods A retrospective analysis was performed on the clinical data of 245 patients with esophageal cancer who received definitive radiotherapy in our hospital from January 2006 to December 2012.One hundred and twenty-six patients received ENI,and the other 119 patients received IFI.Failure patterns were analyzed after treatment.Locoregional failures included local esophageal lesion uncontrol or recurrence and regional lymph node recurrence or metastasis.Distant metastases included distant organ metastasis and distant lymph node metastasis.Comparison of failure pattern between the two therapies was made by chi-square test.Results One hundred and sixty-three patients had failure after treatment.Locoregional failure was observed in 92 patients,distant metastasis in 36 patients,and locoregional failure plus distant metastasis in 35 patients.The 1-,3-,and 5-year overall failure rate for the ENI group were 35.4％,62.5％,and 69.0％,respectively,versus 46.5％,71.5％,and 81.5％ for the IFI group (P =0.036).The 1-,3-,and 5-year locoregional failure rates for the ENI group were 29.9％,48.4％,and 50.0％,respectively,versus 39.6％,62.1％,and 71.4％ for the IFI group (P =0.003).Conclusions For esophageal cancer patients receiving definitive radiotherapy,ENI can significantly reduce locoregional failures and increase locoregional control,thus improving the long-term survival.
