Objective To explore the clinical characteristics and treatment of nodular panniculitis disease in children. Methods Clinical data of 13 cases with nodular panniculitis disease were reviewed retrospectively. Their etiology,clinical manifestation,misdiagnosis cause,pathologic characteristics, treatment and outcome were analyzed. Results Its clinical manifestation was multiform and showed mainly as fever and hypodermic nodule. Concomitant damages to digestive, respiratory, circulatory and renal system might occur in those children with the system type of this disorder. Conclusion Pediatric nodular panniculitis disease can be easily misdiagnosed and lack of specificity in the early stage, and complicates multiple organs damage.

OBJECTIVETo study the effect of oxymatrine on serum cytokines and hepatic fibrotic indexes in patients with chronic hepatitis B (CHB).

METHODSEighty-two CHB patients were randomly assigned to the control group treated with Western routine therapy and the treated group treated by Western routine therapy plus oxymatrine. The treatment course was 24 weeks. Another group with 20 healthy subjects was set as the normal control group. The serum levels of transforming growth factor-beta1 (TGF-beta1), interleukin-6 (IL-6), hyaline acid (HA), collagen type IV (C-IV) and laminin (LN) were measured by ELISA and RIA before and after treatment.

RESULTSThe serum levels of TGF-beta1, IL-6, HA, C-IV and LN in CHB patients were significantly higher than those in the normal control group (P < 0.01). After 24-week treatment with oxymatrine, these abnormal indexes in the treated group were significantly lowered, as compared with those before treatment and in the control group, the differences were significant (all P < 0.01).

CONCLUSIONOxymatrine could lower the levels of cytokines, including TGF-beta1, IL-6, etc. in patients with CHB, which might be one of the mechanisms of its action in reversing liver fibrosis.

OBJECTIVETo discuss the optimal immunization dose by observing the immunoprotective effects of different doses of recombinant Schistosoma japonicum (Chinese strain) signaling protein 14-3-3 (rSj14-3-3).

METHODSSj14-3-3 gene was amplified by reverse transcriptase PCR (RT-PCR), subcloned into prokaryotic expression vector pET28a, then transformed into E.coli to express by inducing. Purified rSj14-3-3 was prepared through SDS polyacrylamide gel electrophoresis (SDS-PAGE), electroelution, dialysis, then BALB/c mice were divided into 5 groups and immunized in rSj14-3-3 protein followed by challenging infection (the 1st, 2nd, and 3rd groups were immunized in 50 microg, 100 microg and 300 microg antigen, respectively. The 4th, 5th groups were immunized in Freund's adjuvant and normal saline controls). After 6 weeks of challenging infection, the mice were killed and the worm and egg reduction rates were calculated. And the mice sera in different time were taken to examine the specific anti-Sj14-3-3 IgG.

RESULTSrSj14-3-3 protein was expressed successfully. After immunizing and challenging, worm reduction was found to be 28.20% in the 1st group, 43.10% in the 2nd group, 40.00% in the 3rd group, respectively. Number of eggs in liver tissue was reduced by 41.80%, 57.50%, 55.70%, respectively. Compared the results of the tested groups to the controls, the differences were of significance by t-test (worm reduction rate: t = 6.8 in the 1st group, t = 8.7 in the 2nd group, t = 7.3 in the 3rd group, P < 0.01 in all tested groups. Egg reduction rate at the group's number above: t = 11.23, t = 11.54, t = 7.99, P < 0.01 in all tested groups). As compared the results between the tested groups by chi(2), the differences were of significance between the 1st and the 2nd groups (worm reduction rate: chi(2) = 8.96, P < 0.05; egg reduction rate: chi(2) = 15.69, P < 0.05), between the 1st and the 3rd groups, the differences were also of significance (worm reduction rate: chi(2) = 6.52, P < 0.05; egg reduction rate: chi(2) = 12.52, P < 0.05). The difference was not of significance between the 2nd and the 3rd groups (worm reduction rate: chi(2) = 1.20, P > 0.05; egg reduction rate: chi(2) = 0.93, P > 0.05). In all tested groups, total anti-Sj14-3-3 specific IgG rose markedly. IgG(1) and IgG(2a) subtypes were high, but IgG(2b) and IgG(3) were near the background in four subtypes tested.

CONCLUSIONImmunoprotection of rSj14-3-3 should have some relations with immunization dose, and the protection obtained from immunizing mice by using 100 microg antigen was the best.

Fingerprint technology is the key technology in modern Chinese medicine research, while spectrum-effect relationship research is the advanced stage of fingerprint research. Spectrum-effect relationship research can reveal the relationship between fingerprint and pharmacological effect through multiple statistical analyses, which can be used in Chinese medicine research. Spectrum-effect relationship has been used in many areas of Chinese medicine research, such as effective basis of single and compound Chinese medicine research, component compatibility research, processing mechanism research, pharmacological effect forecast research, technology optimization research, and so on. This paper systematically reviewed the application of spectrum-effect relationship in Chinese medicine research, and indicated some problems in spectrum-effect relationship research. At last, the authors give an outlook of the future of spectrum-effect relationship research.

OBJECTIVESalmonella isolates recovered from retail meats that were collected in supermarkets and free markets in Xi'an and Yangling areas of Shaanxi province were studied to determine antibiotic susceptibility.

METHODAntimicrobial susceptibility to 14 antibiotics of 193 salmonella isolates were determined by using agar dilution method, which was recommended by National Committee of Clinical Laboratory Standard (NCCLS), and E.coli ATCC25922 and E.faecalis ATCC29212 as standard control strains.

RESULTSThe 44.6% of the salmonella isolates were resistant to sulfamethoxazole, followed by resistance to kanamycin (40.9%), tetracycline (37.8%), amoxicillin (26.9%), ampicillin (25.4%), gentamicin (23.3%) and chloramphenicol (21.8%). Some isolates also showed resistance to fluoroquinolones, the rates for ciprofloxacin, enrofloxacin, levofloxacin and gatifloxacin were 22.3%, 21.8%, 20.8% and 21.2%, respectively. 55 isolates (28.5%) were multidrug resistant (MDR) strains, 28 of 193 isolates (14.5%) could resist at least 13 antibiotics, 24 isolates (12.4%) were resistant to from 4 to 12 antibiotics.

CONCLUSIONSalmonella isolates recovered from retail meats in Xi'an district of Shaanxi province were seriously resistant to antimicrobials commonly used as human and veterinary medicine.

OBJECTIVETo investigate the differential gene expression of ependymomas.

METHODSFour fresh samples of ependymomas and 1 of normal brain tissue were collected during operation. The extracted total RNAs were converted as (32)P tagged cDNA probes, which were then hybridized with the Atlas Human Cancer Array, producing the array based hybridization maps following the protocol provided with the kit. A set of special software was applied to the analysis and RT-PCR was performed to test the result.

RESULTIn comparison with the normal brain tissue, there were 31 upregulated gene and 1 downregulated gene in ependymomas, most of which were firstly found to be differentially expressed in this kind of tumor.

CONCLUSIONThe discrepancy of gene expression profiles between ependymomas and normal brain tissues is highly put through and effectively detected with cDNA array, which provides new information for the further research on the molecular mechanisms of this lesion.

OBJECTIVETo explore the molecular genesis of medulloblastomas with cDNA array.

METHODSFour samples of medulloblastomas and 1 sample of normal brain tissue were collected freshly. After total RNA extraction, the (32)P targeted cDNA probes were converted and then hybridized with Atlas Human Cancer Array 1.2. The gene expression profiles were acquired through autoradiography. The discrepancy between the tumor and the normal brain tissue was analyzed with Atlas Image 1.01a.

RESULTSIn comparison with the genes in the normal brain tissue, 6 down-regulated and 35 up-regulated genes in the medulloblastomas were revealed by means of the microarrays and autoradiography, and were verified by reverse transcriptase-PCR. The regulatory trends of most differential expression genes were in compliance with the biological features of this tumor.

CONCLUSIONMedulloblastomas are diseases involving multiple genes with some molecular pathological mechanisms different from the astrocytic gliomas. There are complex interrelationships between these genes, which need to be further researched.
