OBJECTIVETo observe metabolomic changes in urine of chronic superficial gastritis (CSG) patients with Pi-qi deficiency syndrome (PQDS) or Pi-Wei dampness-heat syndrome (PWDHS), thereby providing scientific evidence for syndrome typing of them.

METHODSUrine samples were collected from CSG patients with PQDS/PWDHS and healthy volunteers, 10 in each group. Proton nuclear magnetic resonance spectroscopy (1H-NMR) based metabonomic analysis was performed on urine samples. Contents of related biomarkers were analyzed by principal component analysis (PCA), partial least square discriminant analysis (PLS-DA), and urivariate statistical analysis.

RESULTSPLS-DA analysis showed that metabolites among CSG patients with PQDS/PWDHS and healthy volunteers could be mutually distinguished. Seven differentially identified metabolites were screened from urines of CSG patients with PQDS and healthy volunteers included glutamate, methionine, α-oxoglutarate, dimethylglycine, creatinine, taurine, and glucose. Four differentially identified metabolites were screened from urines of CSG patients with PWDHS and healthy volunteers included 2-hydroxybutyric acid, trimethylamine oxide, taurine, and hippuric acid. Eleven differentially identified metabolites were screened from urines of CSG patients with PQDS and PWDHS included fucose, β-hydroxybutyric acid, alanine, glutamate, methionine, succinic acid, citric acid, creatinine, glucose, hippuric acid, and lactic acid.

CONCLUSIONThe metabolic differences of CSG patients PQDS and PWDHS mainly manifested in glycometabolism, lipid metabolism, and amino acids catabolism, and 1H-NMR based metabonomics may be used in classified study of Chinese medical syndrome typing.

OBJECTIVETo assess the expression of HER-2 and leptin in gastric cancer and evaluate their relationship with VEGF expression and clinicopathological features, and their prognostic value for gastric cancer patients.

METHODSOne hundred and ten gastric cancer specimens and the corresponding metastatic lymph nodes were detected for HER-2 by immunohistochemistry (IHC). All primary cancer tissues were detected for leptin, OB-Rb and VEGF. Ninty-six specimens of normal gastric mucosa served as the control.

RESULTSThe expression level of HER-2, leptin and OB-Rb in gastric cancer tissues were significantly higher than those in normal tissues (19.1% vs. 8.0%, 49.1% vs. 34.0%, and 60.9% vs. 46.0%, P < 0.05). HER-2 overexpression was moderately homogenous in primary gastric cancer and matastatic lymph nodes (P = 0.607, Kappa = 0.581). There was a correlation between the expression of HER-2 and leptin, both of which were significantly correlated with tumor invasion depth, metastatic lymph nodes ratio (NR), distal metastasis, TNM stage and VEGF expression. However, there was no significant correlation between OB-Rb expression and the clinicopathological features evaluated. Cox regression multivariate analysis showed that tumor size, histological grade, NR, stage, chemotherapy and HER-2 expression were independent prognostic factors.

CONCLUSIONSHER-2 is stably expressed in primary gastric cancer and metastatic lymph nodes. HER-2 and leptin play an important role in the progression and angiogenesis of gastric cancer. High expression of HER-2 is a prognostic factor for poor outcome.

The prevalence of elderly dementia patients in our country is high, the course is long and the cost is high, the visiting rate is low and it is difficult to cure. The implementation of humanistic care to them is the essen-tial demands of medical spirits, also is a necessary supplement to the poor medical treatment and can also give more psychological support to patients and their families. Therefore, it should establish a sound service system, strength-en health education and cultivate professional accompanying staff, in order to enhance the quality of life of elderly dementia patients and improve the living conditions.

Drug allergy and pseudoallergic reactions are main adverse drug reactions. Allergy is mainly induced by the immunogenicity of drug, drug metabolic products or drug additive. Pseudoallergic reactions may result from the irritation or activation of inflammatory material release. Pre-clinical evaluation of drug allergy and pseudoallergic reactions is included in immunotoxicity evaluation. Now there is no in vivo or in vitro method that could predict all kinds of allergy or pseudoallergic reactions due to the different mechanisms. In the past few years, FDA, SFDA OECD, ICH and WHO have published several guidelines on per-clinical immunotoxicity evaluation, however, no agreement has been reached on allergy and pseudoallergic reactions evaluation. This article reviews the requirements of allergy and pseudoallergic reactions in pre-clinical evaluation.

INTRODUCTIONHuman immunodeficiency virus type 1 (HIV-1) genotyping resistance test (GRT) is essential for monitoring HIV-1 drug resistance mutations (DRMs). High cost and HIV-1 genetic variability are challenges to assay availability in Singapore. An in-house Sanger sequencing-based GRT method was developed at the Communicable Disease Centre (CDC), Singapore's HIV national treatment reference centre for both subtype B and non-subtype B HIV-1.

MATERIALS AND METHODSThe in-house GRT sequenced the fi rst 99 codons of protease (PR) and 244 codons of reverse transcriptase (RT) in the pol gene. The results were compared with the Food and Drug Administration (FDA)-approved ViroSeq™ HIV-1 Genotyping System.

RESULTSSubtype assignment for the 46 samples were as follows: 31 (67.4%) CRF01_AE, 14 (30.5%) subtype B and 1 (2.1%) subtype C. All 46 samples had viral load of ≥500 copies/mL, and were successfully amplified by the in-house primer sets. Compared to the ViroSeq™ test, our in-house assay showed drug-resistance conferring codon concordance of 99.9% at PR and 98.9% at RT, and partial concordance of 0.1% at PR and 1.1% at RT. No discordant result was observed.

CONCLUSIONThe assay successfully identified DRMs in both subtype AE and B, making it suitable for the efficient treatment monitoring in genetically diverse population. At less than half of the running cost compared to the ViroSeq™ assay, the broadly sensitive in-house assay could serve as a useful addition to the currently limited HIV genotyping assay options for resource-limited settings, thereby enhancing the DRM surveillance and monitoring in the region.

OBJECTIVETo investigate the clinical efficacy of glucocorticoid combined with ulinastatin in the treatment of Kawasaki disease (KD) in children.

METHODSA total of 104 children who were admitted and diagnosed with typical KD between January 2011 and December 2013 were assigned to ulinastatin group (methylprednisolone+ulinastatin; n=46) and intravenous immunoglobulin (IVIG) group (n=58) according to the severity of KD and the willingness of their parents. Observations for the two groups were performed to compare the changes in coronary artery diameter before and at 1 week, 3 months, and 6 months after treatment, fever clearance time, retreatment condition, changes in white blood cells (WBC), platelets (PLT), hemoglobin (HB), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) at 1 week and 3 weeks after treatment, and total in-hospital cost.

RESYLTSThere was no significant difference in the coronary artery diameter between the two groups before or at 1 week, 3 months or 6 months after treatment (P>0.05). All the patients (100%) in the ulinastatin group vs 83% in the IVIG group had a normal body temperature after 48 hours of treatment (P<0.01). Two patients (4%) in the ulinastatin group and 10 patients (17%) in the IVIG group received retreatment. Significant differences were observed in ESR, WBC, and HB between them (P<0.01). The total in-hospital cost in the ulinastatin group was significantly lower than that in the IVIG group (P<0.01).

CONCLUSIONSFor children with KD, methylprednisolone combined with ulinastatin does not increase the risk of coronary artery aneurysm, decreases in-hospital costs, is superior in controlling laboratory markers and shortening the duration of fever during the acute phase compared with the IVIG therapy.

OBJECTIVETo investigate the relationship of interleukin-10 gene (IL-10) polymorphism and the serum IL-10 level with restenosis after percutaneous coronary intervention (PCI) in Tianjin Chinese Han population and study the effect of IL-10 gene polymorphism on serum IL-10 level.

METHODSFour hundred and thirty-seven patients who successfully underwent PCI with a follow-up angiography were divided into a restenosis group (n = 166) and non-restenosis group (n = 271). The IL-10 gene promoter polymorphism at position -592 was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Meanwhile their serum IL-10 level before and 24 h after PCI was determined by enzyme-linked immunosorbent assay (ELISA).

RESULTS(1) There was no significant difference in frequencies of -592 genotypes and alleles between the two groups (P > 0.05); (2) The 24 h post-PCI IL-10 serum level of restenosis group was significantly lower than that of the non-restenosis group [(82.67 ± 35.02) ng/L vs. (95.08 ± 32.26) ng/L, P < 0.05]; (3) The serum level of the A allele carriers (AA+AC) was significantly lower than that of the CC carriers [(86.13 ± 34.77) ng/L vs. (102.50 ± 27.52) ng/L, P < 0.05]; (4) In the restenosis group, the 24 h post-PCI serum level of IL-10 in the A allele carriers was also significantly lower than that in those without the A allele [(78.51 ± 34.09) ng/L vs. (102.19 ± 33.66) ng/L, P < 0.05]; (5) Logistic regression analysis revealed positive correlations between acute coronary syndrome patients, pre-PCI degree of stenosis, length of target stenosis lesion and restenosis (OR = 5.90, 1.86, 2.83 respectively); and there were negative correlations between 24 h post-PCI serum level of IL-10, the stent diameter, the diameter of reference vessel before stent implantation and restenosis(OR = 0.99, 0.70, 0.46 respectively).

CONCLUSION(1) The IL-10 gene -592 C/A polymorphism was not associated with restenosis in the Tianjin Chinese Han population; (2) IL-10 is an early post-PCI inflammatory cytokine, 24 h post-PCI serum IL-10 level was an independent predictive factor for restenosis, the IL-10 A allele carriers may have increased incidence of in-stent restenosis (ISR) by reducing the serum IL-10 levels.
