0.05).Conclusions Neither the new nor old SIRS diagnostic criteria had a high conforning rate with neonatal critical illnesses;There was no significant difference between them in each clinical item.It shows that the new SIRS diagnostic criteria is not superior to the old one,therefore we should improve the neonatal SIRS diagnostic criteria in the future.

Objective To investigate the expression and significance of Smad4 in peripheral hepatocytes of lesions in mice with hepatic alveolar echinococcosis.Methods Eight mice in the test group were inoculated with alveolar echinococcosis and 8 mice in the control group were injected with normal saline.The expression of Smad4 protein in the hepatic tissue of the mice was detected by immunohistochemistry method,and the data were analyzed by chi-square test.The effect of alveolar echinocoeeosis on the expression of Smad4 protein was investigated.Results Smad4 was detected in cell nuclei and partly in the cytoplasm.Six months after the establishment of the mice model for alveolar echinococeosis,the expression of Smad4 in the hepatic tissue in the test group was significantly higher than in the control group(x2=19.869,P＜0.05).The number of Smad4 with positive expression in the hepatocytes in the test group was slightly higher than in the control group,and the expression intensity of Smad4 in the test group was greater than in the control group(x2=58.3 10,P＜0.05).Conclusions The increase of the expression of Smad4 protein in the periphery hepatocytes and tissues of hepatic alveolar echinococcosis lesions may play a role in hepatic cirrhosis and immune evasion.

Objective To explore change of peripheral blood CD5+B cells in the systemic lupus ery- thematosus(SLE)patients and the association of this change with the disease activity,Methods The percent- age of CD5~+B ceils in peripheral blood in 57 patients with SLE and 35 healthy controls was determined by flow eytometry.Levels of anti-dsDNA,complement C3 and C4,anti-nuclear antibody(ANA),anticardiolipin anti- body(ACL),were also measured.Results The percentage of CD5~+B cell in SLE patients(2.1?0.4)% was high- er than that in normal controls [(1.5?0.4)%](P＜0.05).In active disease group,the percentage of CD5~+B cells [(2.5?0.5)%] was significantly higher than that in inactive SLE patients [(1.4?0.5)% ](P＜0.01).The percent- age of CD5~+B cell associated with anti-dsDNA,ANA,ALA positively,with C3 negatively and had no associa- tion with C4.Conclusion The percentage of CD5~+B cells in the SLE is significantly high and has correlation and some relationship with the SLE.

Objective To prospectively assess the predictive power of centralization phenomenon in the curative effect of automated PLD.Methods The survey population was consisted of 109 patients with inclusion heraiation demonstrated by CT/MRI,74 men and 35 women with average age of 43.1 years(17～75 years). All were complained of low back pain,with varying degrees of lower extremity pain and altered sensation, lasting for more than 2 months;including one symptomatic disc in 99 patients and two symptomatic discs in 10 patients.Patients were undergone dynamic mechanical spinal test and reported whether the test would aggravate their pain.The assessment included forward flexion,extension,rotation of the trunk to the right and left, rotation to the left with fight extension,rotation to the fight with left extension,and whether straight leg raising in the supine position would aggravate back pain or leg pain.Symptom resposes were categorized into three groups:centralization group(CG),partial-centralization group(PCG)and noncentralization group(NCG). Centralization of pain is the progressive retreat of the most distal extent of the referred or radicular pain toward or to the lumbar midline.Noncentralization of pain is the peripheralization of pain in one or more directions, and no change in the distal-most pain location or intensity.All patients received a single therapy with PLD. Results A follow-up of 109 patients for 3 to 6 months,including 46 cases with 24 as exellent and 22 as good reaching 100% of excellent good rate in CG by MacNab standards;43 cases with 5 as exellent,29 as good,9 as fair and poor,with total effective rate of 79.1% in PCG.Twenty cases of NCG symptoms showed no improvement and therefore surgery was considered.Conclusions Centralization phenomenon occurrence during initial mechanical evaluation is a very accurate predictor for successful PLD outcome.Nonoccurrence of centralization would accurately predict poor PLD outcome and thus helpful as early predictor of the need for surgical treatment.

OBJECTIVE: To estimate the application of prognosis evaluation of ulnar nerve injury by 1H-magnetic resonance spectroscopy (1H-MRS). METHODS: The metabolites of first dorsal interossei (FDI) of two hands from 12 healthy volunteers and 1 volunteer with complete ulnar nerve injury were detected by 1H-MRS and the data were statistically analyzed. RESULTS: For the FDI of healthy adults, the female peaks area of extra-myocellular lipids (EMCL) was higher than the male (P < 0.05); There was no significant difference in Cho, Cr and intra-myocellular lipids (IMCL) between male and female (P > 0.05); There was no significant difference in all the peaks area between the left and right hand (P > 0.05). The EMCL peak of the injury side was higher than that of the healthy side, and the area of FDI was reduced in the volunteer with ulnar nerve injury. CONCLUSION Noninvasive and quantitative detection of 1H-MRS may be valuable for prognosis evaluation of peripheral nerve injury.

To discover novel fluoroquinolone lead compounds as possible anti-infective or/and antitumor chemotherapies, combination principle of pharmacophore-based drug design, a series of novel tricyclic fluoroquinolone title compounds, [1,2,4]triazino[3,4-h][1,8]naphthyridine-8-one-7-carboxylic acid derivatives ( 5a-5p), were designed and synthesized with a fused [1,2,4]-triazine ring unit. Their structures were characterized by spectral data and elemental analysis and the in vitro antibacterial and anti-cell proliferation activities were also evaluated. The results showed that the titled compounds exhibited more significant inhibitory activities against drug-resistant bacteria (Methicillin-resistant Staphylococcus aureus and multi drug-resistant Escherichia coli strains) and three tested cancer cell lines (human hepatoma SMMC-7721, murine leukemia L1210 and human murine leukemia HL60 cells). Interestingly, SAR showed that compounds with electron-donating groups attached to benzene ring had stronger antibacterial activity than antitumor activity, but electron-withdrawing compounds displayed more potential antitumor activity than antibacterial activity, especially antitumor activity of nitro compounds was comparable to comparison doxorubicin. Thus, novel triazine-fused tricyclic fluoroquinolones as potent anti-infective or/and antitumor lead compounds are valuable to pay attention and for further development.

BACKGROUNDTo investigate epidemiology and HLA typing of highly exposed to HIV but persistently seronegative subjects (HEPS) in commercial blood donors in China.

METHODSThis was a cohort study for epidemiologic characteristics of highly exposed but persistently seronegative subjects. PCR with sequence-specific primer and PCR-SSP for HLA typing were applied.

RESULTSEight HEPS were identified. Compared HLA typing with seropositive couple, high frequency of HLA-a24, HLA-B40 genotyping was observed.

CONCLUSIONHighly exposed to HIV but persistently seronegative subjects in commercial blood donors in China had high frequency of HLA-A24 and HLA-B40 genotype.

OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).

METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.

RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.

CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.
