Objective To investigate the changes of the pulmonary surfactant protein-D (SP-D) in serum and cerebrospi-nal lfuid in children with viral encephalitis (VE). Methods The levels of SP-D in serum and cerebrospinal lfuid were detected by a double-antibody sandwich enzyme-linked immunosorbent assay and compared in thirty children with VE in acute and con-valescent phases and in 12 children without VE. Results The levels of SP-D in serum and cerebrospinal lfuid between groups of VE acute phase and convalescent phase and no VE were statistically signiifcant (F=103.58,118.15, all P<0.01). The levels of SP-D in serum and cerebrospinal lfuid in children with VE in acute phase and in convalescent phase were signiifcantly lower than children without VE (P<0.01). The levels of SP-D in serum and cerebrospinal lfuid in children with VE in convalescent phase were all signiifcantly higher than those in acute phase (P<0.01). In children with VE, the level of SP-D in cerebrospinal lfuid was weakly correlated negatively with the count of nucleated cells. Conclusions SP-D might be involved in the pathogenesis in VE. The detection of SP-D in serum and cerebrospinal lfuid has a certain value for diagnosis of VE.

Objective To investigate the renoprotective effect of irbesartan on tubulointerstitial fibrosis in rats with adriamycin-induced nephropathy and its possible mechanism. Methods Rats received twice-intravenous injections of adriamycin(ADR) after the right kidney was removed. Those rats were randomly assigned to irbesartan treatment group and nephropathy group. Treatment group received 50 mg? kg-1 ? d-1 irbesartan for 4 weeks. Rats with sham operation served as normal control. Proteinuria and serum creatinine of were measured after 4 weeks. Renal histopathological changes were evaluated as well. Immunohistochemistry was used to examine the protein expression of TGF-?1, MMP-9 and TIMP-1. The mRNA levels of MMP-9 and TIMP-1 were detected by in situ hybridization. Results Proteinuria of treatment group decreased significantly as compared to nephropathy group. TGF-?1, TIMP-1 and MMP-9 were significantly lower than that of nephropathy group in tubulointerstitium and consistently associated with tubular degeneration and interstitial fibrosis progressed. Conclusion Irbesartan has a renoprotective effect on tubulointerstitial fibrosis by modulating the ECM degradation.

The article aims to introduce a creative desensitization therapy to enrich modem clinic psychological treatment. The imaginary desensitization in the static state of Qigong is one method of the systemic Chinese medicine psychological treatments (SPT). It is suitable for the Chinese cultural background and the psychological characteristics of Chinese people.

The hemorrhage during laparoscopic cholecystectomy (LC) in operating field is a significant puzzle worries the surgeon. Besides disrupting the cystic artery hemorrhage originating from the gallbladder bed also plays a frequent role in the cause of bleeding in LC. The gallbladder bed bleeding which results from the disrupt of the branches of the middle hepatic vein is a ticklish problem in the operation. It will complicate the surgical operation, confuse the anatomic structttre, cause serious complications and is a main reason for conversion. Thus, we compose this review to expound the topographic anatomy of the branches of the middle hepatic vein as well as the prevention and treatment to the injure of the branches of the middle hepatic vein.

Objective To introduce an interpersonal relationship regulating technique in the static state of Qigong to enrich modern clinical psychotherapies. Methods Based on previous therapeutic experience, we introduce one specific technique of the Systematic Psychotherapy of TCM (SPT): Interpersonal relationship regulating technique in the static state of Qigong. Results Interpersonal relationship regulating technique in the static state of Qigong is a specific and practical technique of SPT, which has been gradually standardized and been mature with more than two decades of innovation and accumulation. Conclusion Interpersonal relationship regulating technique in the static state of Qigong has great clinical value.

Objective To establish a method for quantitative determination of 17 kinds of organophosphates pesticides in vegeta‐bles by gas chromatography and mass spectrometry (GC‐MS) .Methods The sample was extracted by acetonitrile ,purified by the a‐mino solid phase extraction small column ,concentrated ,detected by GC‐MS .Then the ion scanning (SIM ) mode was selected to mo‐nitor the specific iron in target compound for conducting the quantitative analysis .Results 17 kinds of compound had good linearity in the limit of detection (LOD) of 0 .001 - 0 .02 mg /kg (S/N = 3) with a relative standard deviation of 1 .05% - 6 .81% ,and the re‐covery rate was 66 .4% - 99 .3% when with cap at 004 ,008 ,0 .40 mg/kg .Conclusion This method has good selection and high sensitivity ,and is suitable for the rapid determination of organophosphates pesticide residues in vegetables .

Objective To develop a rat model of type 2 diabetes, and to investigate the effect of AT1 receptor antagonist-irbesartan on activation of renal NF-?B in type 2 diabetic rat. Methods The rats of model groups were intraperitoneally given low-dose streptozotocin (STZ, 30 mg/kg) after having the sucrose-and fat-enriched diets(20% sucrose, 10% pig fat, 2. 5% cholesterol) for one month. Immuohistochemistry and computer image-pattern analysis system were used to analyze activation of NF-?B and expression of monocyte/macrophage (ED-1) in renal tissues. Results (1) Insulin resistance was induced by feeding diets enriched in sucrose and fat, and hyperglycemia was induced with a dose of STZ that did not cause diabetes in chow-fed rats. After 6 weeks, rats of model group presented itself early changes of diabetic nephropathy (DN). (2) Compared to normal group, the activation of NF-?B and expression of ED-1 increased in glomeruli of experimental type 2 diabetic rat. Irbesartan inhibited significantly the activation of NF-?B, ameliorated monocyte/macrophage infiltration, partly improved the renal function and matrix accumulation. Conclusions (1) A rat model of type 2 diabetes mellitus is developed successfully by combination of dietary-induced insulin resistance and low-dose STZ-induced hyperglycemia. (2) Renal NF-?B activation is greatly increased in experimental type 2 diabetic rat. The protection of irbesartan against kidney is associated, at least in part, with down-regulating NF-?B activation and monocyte/macrophage recruitment in renal tissue.

AIM To establish radioligand binding assay of PAF (platelet activating factor) receptors in mouse peritoneal macrophages and observe the characteristics of PAF receptors. METHODS PAF receptor radioligand binding was studied in intact adherent mouse peritoneal macrophages by -PAF. The radioactivity was counted with an LS6500 scintillation system. RESULTS The PAF receptor binding was shown to be saturable with an equilibrium K D of 3.2 nmol?L -1 and a B max of 100.2 fmol?1?10 6 cells -1. The competitive analysis showed that such specific binding could be inhibited by BN52021. CONCLUSION Utilizing the adherent character of macrophages, the binding ligands could be separated from non-binding ligands without negative pressure filtration, then cells could reserve fine activity, and PAF receptors could be near to physiological properties for screening of PAF antagonist.

Objective To investigate whether the signaling pathway of PI3K-AKT is involved in Ang II-induced apoptosis in rat renal tubular epithelial cells (NRK-52E).Methods Cultured cells were incubated in media containing either buffer (control) or different concentrations of Ang II (10-9 to 10-6 mol/L) for 24 h. Cells were stained by Annexin V-F1TC/PI Kit and apoptosis was evaluated by flow cytometer. Western blotting was performed to assess the levels of PI3K, total- and phosphor-AKT. Results Ang II induced tubular epithelial cell apoplosis in a dose dependent manner. Ang II significantly inhibited the phosphorylation of AKT. The level of AKT phosphorylation was negatively correlated with apoptosis in Ang II-stimulated cells(r=-0.90 ,P
