Totally 80 rats were randomly divided into the control group, the model group, low, middle and high dose (25, 50, 100 mg x kg(-1)) scutellarin( SC) groups and the colchicine ( Col) group. Apart from the blank group, all of the remaining groups were intraperitoneally injected with 0.5 mL pig serum twice every week for consecutively 13 weeks and orally administered with the corresponding drugs since the 9th week. The blank group and the model group were orally given equal volume of normal saline once every for consecutively four weeks. After the experiment, efforts were made to detect the contents of alanine aminotransferase (ALT), aspertate aminotransferase (AST), albumin (ALB), total protein (TP), total bilirubin (TBIL), hyaluronic acid (HA), laminin (LN) and collagen type IV (CIV), collect liver tissues of fixed positions, observe the pathological changes through hematoxylin-eosin (HE) staining, conduct the pathological grading for liver fibrosis, determine the expressions of hepatic collagen type I and III (C I, C III) and calculate their color rendering index. Compared with the model group, low, middle and high dose (25, 50, 100 mg x kg(-1)) SC groups could decrease the contents of ALT, AST, TBIL, HA, LN, CIV, increase the contents of ALB, TP in serum and reduce the contents of C I, C III in liver tissues. In conclusion, scutellarin has a certain therapeutic effect on immune liver fibrosis in rats induced by pig serum.

Objective To explore the function of scavenger receptor class B type I(SR-BI)in the human peripheral blood monocyte expression of proinflammatory cytokines mRNA induced by oxidized low density lipoprotein(OxLDL). Methods With the digoxenin-labeled oligonucleotide-probes in situ hybridization, we investigated the effects of OxLDL, fucoidin and 17?-estradiol on the primarily-cultured human peripheral blood monocyte mRNA expression of SR-BI and relationship between its expression and the mRNA expressions of MCP-1, bFGF, PDGF and IL-10. Results The mRNA expression of SR-BI was significantly increased in a dose-dependent manner after incubating with OxLDL (10～30 mg?L -1)(P

This paper collected and analysed the materials concernig constitution and the nutritional level of the diets of inhabitants in Dandong city from 1959 to 1985. The results showed 1) Nutrients level of the diets increased with years and became rational. Intakes of energy and protein were over 110% and 97.1% of the RDA:the protein provided 10.5%, fat 30% and carbohydrate 58% of total energy intake; and 13.2% of protein originated from animal sources. 2) The weight of new-borns and children was less than that in developed countries. 3) The weight of children at age 8 and 14 increased 0.11 (boy), 0.06 (girl) and 0.33, 0.2lkg respectively. The height of the boys increased 0.37, 0.51 cm and the girls 0.28, 0.30 cm respectively. The increased rate is quicker. 4) At the age 0-7, the incidence of the des-eases caused by malnutrition declined yearly but incidence of rickets dropped down less. This may concern less sunning and less VD of the diets.

BACKGROUND: Inflammatory mediators-induced neurodocitis in the nucleus pulposus is a main factor for backleg pain. Receptor pathway studies confirmed that the nervous system had self-circulation. Administration by receptors has the same effect as targeting drug delivery. OBJECTIVE: To evaluate the therapeutic efficacy of drug injection on synovium of lumbar zygapophyseal joints and muscular attachment point of neural scute in 1 236 patients with discogenic low back pain. DESIGN,TIME AND SETTING: The case analysis experiment was performed at the First People’s Hospital from March 2002 to March 2007. PARTICIPANTS: 1 236 patients with discogenic low back pain were selected at the Department of Pain,including 370 males and 866 females,aged from 20 to 80 years. The patients accompanied with bulging of lumbar intervertebral disc and protrusions less than 1/3 vertebral canal. METHODS: Drugs were injected on bulges of lumbar intervertebral disc,protuberate zygapophysis and neural scute. General pharmaceutical formulation: Betamethason copound injection 5 mg+ levofloxacin 0.1 g+20 g/L lidocaine 5 mL+sacine metered to 20 mL+ sodium hyaluronate 20 mg. The administration was once a week and one course of treatment had three administrations. There was no overweight loading during one month. MAIN OUTCOME MEASURES: Therapeutic efficacy; relapse rate. RESULTS: In 1 236 patients with one course of treatment,there were healing in 1 142 cases (94%),improvement in 89 cases (7.2%),inefficacy in 5 cases (0.4%). In 322 patients with one year consummate data,there were no relapse in 250 cases (77.6%),relapse in 72 cases (22.4%). In 206 patients with two year consummate data,there were no relapse in 155 cases (75.2%),relapse in 51 cases (24.8%). In 91 patients with three year consummate data,there were no relapse in 74 cases (81.3%),relapse in 17 cases (18.7%). In 62 patients with four year consummate data,there were no relapse in 52 cases (83.8%),relapse in 10 cases (16.2%). In 32 patients with five year consummate data,there were no relapse in 27 cases (84.3%) and relapse in 5 cases (15.6%). CONCLUSION: Drug injection on synovium of lumbar zygapophyseal joints and muscular attachment point of neural scute through receptor-mediated pathway is simple and available in patients with discogenic low back pain.

Objective To evaluate the diagnostic value of fluorescent quantitative polymerase chain reaction(PCR) for Mycoplasma pneumoniae (MP) in children with MP pneumonia(MPP).Methods From Jun.2008 to Jan.2009,153 cases hospitalized with pneumonia were enrolled,and 30 cases without respiratory infection were enrolled as control group.Their respiratory secretion (including nasopharyngeal secretion,sputum,bronchialalveolar lavage fluid or pharyngeal swab) samples were collected for fluorescent quantitative PCR for MP.And their single or paired serums were collected for specific MP antibody detection.Results There were 123 cases confirmed with MPP by serology,among whom 114 cases were MP PCR positive.The quantitation of MP DNA was among 1.20?106-3.66?1010 gene copys/L. There were 30 cases with pneumonia negative with MP by the paired serum serology,among whom 2 cases were MP PCR positive,and the quantitation of MP DNA was (1.08-3.02)?107gene copys/L.All cases of control group were MP PCR negative.During the first and second weeks of the MPP onset,the sensitivity of MP-IgM from the first single blood samples were 66.7% and 83.9%,respectively.While the sensitivity and specificity of MP PCR were 92.7% and 93.3%,respectively.From the third week of the disease onset,the sensitivity of MP-IgM from the first single blood samples increased to 90.9%-100%.The clinical manifestations of MPP were nonspecific.Conclusions PCR is superior to serology for early diagnosis on MP infection.Combination of the 2 methods may be helpful to early and accurate diagnosis on MP infection.

Objective To explore the clinical characteristics,diagnosis,treatment and misdiagnosis matter of children with idiopathic pulmonary hemosiderosis(IPH).Methods The data of clinical characteristics,laboratory examination,treatment and follow-up of 21 children admitted from Jun.1993 to May 2007 were retrospectively analyzed,included 9 males,12 females,aged 1-14 years old,course of di-sease were 1-6 months.Twenty-one patients were diagnosed as IPH by chest X-ray radiography,CT scan,bone marrow biopsy,hemosiderin-laden macrophages in either sputum or gastric juice or bronchoalveolar lavage fluid.Then,therapy and prognosis of IPH were analyzed.Results All patients had varied degrees of anemia,11(52.38%) children had cough,9 (42.86%) children had fever,6(28.50%) cases had shortage of orexia,4( 19.05%) children had hemoptysis.Chest X-ray radiography and CT scan demonstrated diffuse patchy,nodular,reticulate pattern.Eighteen children received bone marrow biopsy and presented hyperplastic erythropoiesis,4(22.2%) cases were accompanied iron deficiency anemia.Nineteen (90.80%) cases shown the presence of hemosiderin-laden macrophages in either sputum or gastric juice or bronchoalveolar lavage fluid.Twenty-one misdiagnosed patients consisted of bronchopneumonia combined anemia(8 cases),lung tuberculosis combined anemia(5 cases),nulli-iron anemia(4 cases),hemolytic anemia(3 cases),myelodysplastic syndrome(1 case)and received corticosteroid therapy.Four cases of all patients were associatated with large-dose human-?-globulin and 3 cases were associatated with vincristine therapy.The therapeutic effect was significant.Eighteen patients were followed-up,3 patients were of which cured and had stopped treatment for over 2 years,11 patients presented clinically persistent remission,4 patients were recurred and aggravated.Conclusions Early diagnosis and long-term therapy of corticosteroid are very important for controlling acute onset,lessening the frequency of IPH recurrence and improving prognosis of the disease.

AIMTo study the protective action of ulinastatin against lipopolysaccharide (LPS)-induced acute lung injury in mice and the mechanism of its action.

METHODSMice were intraperitoneally injected with ulinastatin (50 and 100 ku x kg(-1)) or saline at a period of 12 h, separately, 30 min after the last injection of ulinastatin, except normal control, all mice of other groups were injected a dose of LPS 15 mg x kg(-1) via tail vein. The levels of TNFalpha in serum and lung were measured by ELISA. The expression of TNFalpha mRNA and iNOS mRNA in lung was assayed by RT-PCR. The expression of c-Fos and c-Jun protein in lung was measured by Western blotting method. And the NO2- / NO3- level in serum and MDA in lung were measured with kits.

RESULTSThe levels of NO2- / NO3- and TNFalpha in serum, MDA and TNFa in lung all increased after iv injection of LPS. The expressions of TNFa mRNA, iNOS mRNA, c-Fos and c-Jun in lung of LPS-injected mice were enhanced. Pretreatment with ulinastatin 100 ku x kg(-1) decreased the levels of NO2- / NO3- in serum and lung, reduced the index of lung, and inhibited the expressions of iNOS mRNA and c-Jun in lung induced by LPS in mice, while ulinastatin showed no effect on TNFa level in serum and lung.

CONCLUSIONUlinastatin protected mice from acute lung injury induced by lipopolysaccharides via inhibiting the activation of c-Jun and iNOS mRNA expression.
