Objective To explore the value of color doppler ultrasonography by bed side in the early diagnosis of HIE in full term neonates.Methods The changes of cerebral parenchymal and cerebral arterial blood stream parameter on 35 cases of neonates clinically diagnosed HIE of mild and moderate degree and 40 cases of normal newborns on the 24,48 and 72 hours after birth were observed by color doppler ultrasonography by bed side.Results 1.The cerebral parenchyma was even echo in normal newborns,but it was maldistributed and reinforced in mild asphyxia neonates and it was more serious in moderate degree.The echo of cerebral parenchyma in mild degree was near normal in 48 hours after birth,while the echo of cerebral parenchyma in moderate degree was still maldistributed and reinforced in 48 and 72 hours after birth.2.There was obvious changes in the cerebral arterial blood stream parameter and hemodynamics of the asphyxia newborns compared with normals.The systolic peak velocity(Vs)and end diastolic velocity(Vd)of the cerebral arteries in mild and moderate degree were obviously lower than that of control group in 24,48 hours after birth(Pa0.05).3.Resistance index(RI)of the cerebral arteries in mild and moderate degree were higher than that of control group in 24,48 hours after birth(Pa0.05).Conclusion Color doppler ultrasonography by bed side is a convenient,noninvasive method for diagnosing HIE.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

OBJECTIVETo explore the influence on AM fungi infection rate and medicine quality of Pinellia ternate in the condition of three soil impact factors.

METHODSet the orthogonal test of three factors and levels. Determinate the AM fungi infection rate in early stage of mature & stage of mature of P. ternata, and the water content, water soluble extract, butanedioic acid content and alkaloid content of P. ternata tuber that be harvested also had be determinated.

RESULT AND CONCLUSIONWith the P levels to 30 mg x kg(-1) and 90 mg x kg(-1), AM fungi infection was the best when mixed inoculated of EM. Microbial agent inoculated played a decisive role in P. ternata growth and physiological activity, secondary influenced factor was P concentration, and the water stress was the minimal impact. Mixed inoculated of AM fungi and EM treatment with the low P levels (30, 90 mg x kg(-1)) proved better effect on enhancing the water extract content, anedioic acid and alkaloid content, while decreasing the water contents of P. ternata tuber.

BACKGROUNDAllergic asthma is associated with airway inflammation and hyperresponsiveness caused by dysregulated production of cytokines secreted by allergen-specific helper T-type 2 (Th2) cells. The linker for activation of T cells (LAT) is a membrane-associated adaptor protein, which has been shown to take part in regulating T cell receptor (TCR) signaling and T cell homeostasis. In this study, we established an asthmatic mouse model to examine the changes in LAT levels during allergic airway disease and the effects of LAT transgenic expression on airway inflammation.

METHODST cells from mouse lung tissues were isolated from allergen challenged (ovalbumin (OVA)) and control mice, and the purity of these isolated T cells was examined by fluorescence-activated cell sorter (FACS). Semi-quantitative RT-PCR and Western blotting were used to detect the expression of the LAT gene and LAT protein, respectively. After an intranasally administered mixture of pCMV-HA-LAT plasmid and Lipofectamine 2000, 24 hours before and 72 hours after allergen challenge, the BALF cell count and the differential cytologies were studied. In addition, IL-4 and IFN-γ levels in the BALF were determined by ELISA, and pathological changes in lung tissues were observed.

RESULTSLAT protein and mRNA expression were decreased in lung T cells in a mouse model of allergen-induced airway disease. After intranasal administration of pCMV-HA-LAT, histopathological examination of the lungs showed that intervention with LAT overexpression prevented mice from developing airway inflammation, and the number of total cells, eosinophils, neutrophils, and lymphocytes in the BALF was reduced significantly compared with the OVA sensitized and challenged group. In addition, the Th2 cytokine IL-4 decreased, while the Th1 cytokine IFN-γ increased compared to the OVA sensitized and challenged group or the OVA sensitized group plus pCMV-HA treatment.

CONCLUSIONThis study demonstrates that LAT might effectively diminish Th2 cytokine responses, lung histopathological changes and lung inflammation to allergen challenge in a model of experimentally induced asthma.

AIMTo investigate the spatial and temporal expression of germ cell nuclear factor (GCNF) in mouse and rat epididymis during postnatal period.

METHODSThe epididymal sections from different postnatal days were stained for GCNF by the indirect immunofluorescence technique and digital photographs were taken by a Carl Zeiss confocal microscope.

RESULTSGCNF was first detected on day 12 in mouse epididymis and day 14 in rat epididymis. The highest expression of GCNF was observed on day 35 in both mouse and rat epididymis. In adults, GCNF exhibited a region-specific expression pattern, i.e., it was expressed predominantly in the initial segment, caput and proximal corpus of rat epididymis and was abundant in the proximal corpus of mouse epididymis. GCNF could be found in the nuclei of the principal, apical, narrow, clear and halo cells.

CONCLUSIONGCNF may play an important role in epididymal differentiation and development and in sperm maturation.

OBJECTIVE: To explore the clinical efficacy of intrathecally administered low dose sufentanil-bupivacaine in transurethral resection of the prostate (TURP). METHODS. Ninety patient (ASA I - III) undergoing TURP were randomly divided into 3 groups (n = 30); Group A, B and C. Group A received 7.5 mg bupivacaine + 5 microg sufentanil + 10% glucose; Group B received 7.5 mg bupivacaine + 7.5 microg sufentanil + 10% glucose; Group C received 15 mg bupivacaine + 10% glucose. The volume was 3 mL in every group. SP, DP, HR, SpO2, the degree of motor and sensory blockade and the side effect were observed. RESULTS: SP/DP was significantly decreased in Group C than that in Group and Group B (p<0.05), HR and SpO2 in group B were decreased to different degrees 15 min after the injection (p<0.05). The complete recovery time of motor nerve blockade and the regression time of sensory blockade were obviously prolonged in Group C (p<0.05). There were no significant differences in analgesic effect among the three groups during the operation, but the incidence of pruritus was higher in both group A and Group B than that in Group C during the first 24 hours after the injection. CONCLUSION Spinal anesthesia with low dose sufentanil-bupivacaine possesses relatively steady hemodynamics. The blockade degree of motor and sensory blockade in this spinal anesthesia is lower than that in standard spinal bupivacaine in TURP.
