OBJECTIVETo investigate the frequency and type of PHEX gene mutations in children with X-linked hypophosphatemic rickets (XLH), the possible presence of mutational hot spots, and the relationship between genotype and clinical phenotype.
METHODSClinical data of 10 children with XLH was retrospectively reviewed. The relationship between gene mutation type and severity of XLH was evaluated.
RESULTSPHEX gene mutations were detected in all 10 children with XLH, including 6 cases of missense mutation, 2 cases of splice site mutation, 1 case of frameshift mutation, and 1 case of nonsense mutation. Two new mutations, c.2048T>C and IVS14+1delAG, were found. The type of PHEX gene mutation was not associated with the degree of short stature and leg deformity (P=0.571 and 0.467), and the mutation site was also not associated with the degree of short stature and leg deformity (P=0.400 and 1.000).
CONCLUSIONSMissense mutation is the most common type of PHEX gene mutation in children with XLH, and c.2048T>C and IVS14+1delAG are two new PHEX gene mutations. The type and site of PHEX gene mutation are not associated with the severity of XLH.

OBJECTIVETo evaluate the value of high mobility group box 1(HMGB1) in the diagnosis of pediatric acute appendicitis.
METHODSThe children with acute abdomen who had a diagnosis of suspected acute appendicitis between January and July 2013 and 25 healthy children were enrolled in this study. Serum HMGB1 levels were measured using ELISA on admission. The patients were classified into 2 groups according to surgery confirmation or pathological results: appendicitis (n=28) and non-appendicitis (n=35).
RESULTSSerum HMGB1 levels and WBC in the appendicitis and non-appendicitis groups were significantly higher than in the healthy children group (P<0.01). The appendicitis group showed more increased serum HMGB1 levels compared with the non-appendicitis group (median: 32.9 ng/mL vs 22.0 ng/mL; P<0.01). For a diagnosis of acute appendicitis, the sensitivity and specificity of serum HMGB1 was 71.4% and 82.9% respectively at the best cutoff of 28.0 ng/mL, with the accuracy of 77.8% and the area under the curve of 0.765 (95%CI 0.638-0.893).
CONCLUSIONSHMGB1 may play a role in the diagnosis of pediatric acute appendicitis.

To prepare the derivatives of salicylic acid-g-chitosan and study their synergistic and complementary actions, the synergism of anti-inflammatory action of the derivatives was investigated with the experiments of xylene-induces mice ear edema, the analgesic activities by the tartaric emetic-induced mice twist test and the hot-plate test, and the complementary effects between salicylic acid and chitosan through morphological changes of stomach mucous membrane of rat, separately. The anti-inflammatory activities of salicylic acid-g-chitosan derivatives for anti-inflammatory activities were more potent than that of salicylic acid and chitosan and dexamethasone cream in external use, and more potent than that of aspirin orally. However, immediate analgesic activity of the derivatives was lower than that of aspirin and persistent activity was similar as that of aspirin. And the stomach mucous membrane morphology change of the derivatives was much milder than that of aspirin. The salicylic acid grafted chitosan derivatives showed synergistic and complementary effect on the anti-inflammatory and analgesic activities and so on.

AIM: To investigate the protective effect of huoxuehuayu decoction on macula after phacoemulsification. Into A, B groups. The 80 eyes of A group were treated by conventional phacoemulsification; the patients (60 eyes) of B group were given huoxuehuayu decoction orally for two courses after phacoemulsification. Best-corrected visual acuity(BCVA), corneal and aqueous conditions ,thickness of macular central fovea and changes of macular retinal tissue in A, B groups were observed before surgery, 1 day; 1 week,2,4,6,8 weeks and 3 months after surgery. Was significantly higher than that of group A. One week after surgery the ratio of mild aqueous flare in group B was significantly lower than that of group A. The thickness of central fixation was significantly increased in both groups 1 week, 2, 4, 6, 8 weeks and 3 months after phacoemulsification; the difference between 2 to 8 weeks after surgery and pre-operation showed statistical significance in both groups. 11 eyes in A group had macular edema during 2 to 6 weeks after surgery, including 9 eyes with fovea thickened and 2 eyes with cystoid macular edema, and seven eyes' edema disappeared in 3 months. 2 eyes in B group had macular edema, including 1 eye fovea thickened and 1 eye cystoid macular edema, during 4 to 6 weeks after surgery, and the two eyes' edema disappeared 3 months after surgery. The fovea thickness in group B during 2 to 8 weeks after surgery was statistically lower than group A. Phacoemulsification.

OBJECTIVETo explore the impact of environmental factors, daily lifestyle, psycho-social factors and the interactions between environmental factors and chemokines genes on systemic lupus erythematosus (SLE).
METHODSCase-control study was carried out and environmental factors for SLE were analyzed by univariate and multivariate unconditional logistic regression. Interactions between environmental factors and chemokines polymorphism contributing to systemic lupus erythematosus were also analyzed by logistic regression model.
RESULTSThere were nineteen factors associated with SLE when univariate unconditional logistic regression was used. However, when multivariate unconditional logistic regression was used, only five factors showed having impacts on the disease, in which drinking well water (OR=0.099) was protective factor for SLE, and multiple drug allergy (OR=8.174), over-exposure to sunshine (OR=18.339), taking antibiotics (OR=9.630) and oral contraceptives were risk factors for SLE. When unconditional logistic regression model was used, results showed that there was interaction between eating irritable food and -2518MCP-1G/G genotype (OR=4.387). No interaction between environmental factors was found that contributing to SLE in this study.
CONCLUSIONMany environmental factors were related to SLE, and there was an interaction between -2518MCP-1G/G genotype and eating irritable food.

OBJECTIVETo explore the effect of recombinant human erythropoietin (rhEPO) on expression of brain-derived neurotrophic factor (BDNF) in different brain regions of aging rats.
METHODSForty male SD rats were randomized equally into negative control group, D-galactose group, EPO treatment group, and positive control group. Rat models of subacute aging were established by continuous subcutaneous injection of 5% D-galactose. Immunohistochemical staining was used to analyze the variation of BDNF expressions in different brain regions of the aging rats with different treatments.
RESULTSSignificant brain region-specific differences in BDNF expression were found among the rats in different groups. Compared with those in the negative control group, the numbers of BDNF-positive cells in the hippocampal CA1 region, CA3 region, dentate gyrus (DG) and frontal cortex were all decreased obviously in D-galactose group (P<0.05) but increased in both EPO group and the positive control group (P<0.05) without significant differences between the latter two groups. In the rats in the same group, the number of BDNF-positive cells varied markedly in different brain regions (P<0.05), and the expression level of BDNF was the highest in the frontal cortex followed by the hippocampal CA3 region and the dentate gyrus, and was the lowest in the hippocampal CA1 region.
CONCLUSIONTreatment with rhEPO enhances the expression of BDNF in rat neural cells, suggesting that rhEPO may protect the nervous system from aging by regulating the BDNF pathway.
