Objective To investigate the hypothesis that food allergy in infants may be associated with variation in their intestinal microflora. The formation of intestinal microflora in healthy infants and changes in food allergic infants were detected.Methods 16S rRNA gene sequences specific for bifidobacterium, lactobacillus and escherichia coli in fecal were quantitatively detected by real-time PCR. The three fecal floras were assessed in 71 healthy infants and 100 infants with food allergy. Results After birth,there were bifidobacteria colonized in infantile intestine,then the number increased rapidly up to 5 times at the sixth month, which was always the preponderant flora. Lactobacilli was also presented in infantile intestine 1 month after birth and augment gradually. The number of Escherichia coli was less than bifidobacteria and lactobacilli and appeared to decline during the early infants. The number of bifidobacteria and lactobacilli in the infants with food allergy were markedly less than that in the healthy infants, but escherichia coli was significantly more than that in the healthy infants.Conclusions During the first year of life,the intestinal microflora in infants is in a developing process. Compared with the healthy infants,bifidobacteria and lactobacilli decrease, but escherichia coli increase in the food allergic infants.These results indicate that the probiotics may be benefit to the prevention and treatment of food allergy.

This paper briefly analyzed and discussed the current status and major scientific challenges of traditional Chinese medicine (TCM) formulaology research. To promote formulaology research, a new strategy and corresponding technology, network formulaology, were proposed to reveal the complex interaction between functional chemome and biological responses network. The research framework and directions of network formulaology were also summarized and prospected.

Objective To study the distribution of IL-10 and TNF gene polymorphisms in patients with gastroduodenal diseases in Hubei Han ethnic and their association with Helicobacter pylori (Hp) infection. Methods Six hundred and five patients with gastroduedenal diseases (196 chronic gastritis, 189 gastroduodenal ulcer and 220 gastric cancer) as well as 624 healthy controls were genotyped with PCR-RFLP method for IL-10-1082,-819,-592 and TNFα-308, lymphotoxin-α (LTα) Nco Ⅰ and AspH Ⅰ gene polymorphisms. Hp infection status was determined with ELLS& Results (1) There was significant difference of IL-10-1082 AG + GG genotype among the gastric cancer group with the non-malignant gastric diseases groups and healthy control group (P <0. 05). There was no significant difference of IL-10-592 and -819 gene polymorphisms among gastric cancer patients,non-malignant gastric disease patients and healthy controls (P>0. 05). The genotype frequencies of IL-10-819 were the same as those of IL-10-592. (2) Frequency of IL-10-1082 AG + GG genotype in gastric cancer patients with positive Hp was significantly higher than that in the other three groups (P < 0. 05). (3) Frequency of LTα Nco I AG genotype in gastric cancer patients with Hp infection was signiilcandy higher than that in Hp positive healthy controls (P < 0. 05). There were no other associations between TNFα-308, LTα Nco Ⅰ and AspH Ⅰ gene polymorphisms and Hp infection in gastroduodenal diseases. Conclusions (1) Allele AG + GG of IL-10-1082 was associated with gastric cancer in Han nationality of Hubei province. (2) IL-10-1082 AG + GG,LTct Nco ⅠAG heterozygous genotype may be associated with Hp infection in patients with gastric cancer in Han nationality of Hubei province.

Objective To investigate the gene-expression profile in kidney of rats during late sepsis (24hours) by using microarray technology in order to offer some clue to revealing the pathogenetic mechanism of sepsis at gene level. Method A total of 30 Wistar rats were selected and divided into model group and control group randomly(random number). The rats of control group were sham operated and the rats of model group received cecal ligature and puncture (CLP) operation. The biomarkers of renal function were assayed and the histopathological changes of kidney in rats were observed under transmission electron microscope 24 hours after operation. Gene chips containing 22 107 rat-genes cDNA were used to exmine gene-expression in kidney of septic rats to sieve the genes with different expressions with software. Data were analyzed by using SPSS version 11.0 software package.Statistical analyses of two independent samples carried out by using t -test. Results Compared with the control group, the levels of blood urea nitrogen (BUN) and creatinine (Cr) of sepsis group were higher (P < 0.01 ). The histopathological changes in kidney of rats demonstrated the establishment of sepsis model successful 24 hours later.Compared with the control group, there were 325 genes with differential expression in model group. Among the known-functional genes, there were 100 up-regulated and 64 down-regulated. Sorted by biological function, the genes were mainly related to metabolism, immunoresponse, cellular signal transduction, apoptosis, ion channel,growth factor and so on. Conclusions A sequence of genes expressed differentially in kidney of rats with late sepsis. Microarray technology played an important role in the research into sepsis mechanisms.

AIM: To observe the role of confocal microscopy in infectious keratitis management.
METHODS:Totally 466 patients (467 eyes) diagnosed as infectious keratitis from January 2010 to December 2013 were retrospectively studied. the corneas were examined early by in vivo confocal microscopy. The characteristics of their images and clinical features were studied and summarized.
RESULTS:All patients were recorded, the average age was 54. 4±13. 0 years, in which 264 cases (56. 7%) were male, and 202 cases ( 43. 3%) were female. In the 466 patients, 190 (40. 8%) were fungal keratitis, 148 (31. 8%) were viral keratitis, 125 (26. 8%) were bacterial keratitis and 3 ( 0.6%) were acanthamoeba keratitis. There were fungal hyphae in the images of fungal keratitis. Amebic cysts were found in acanthamoeba keratitis.
CONCLUSION:Confocal microscope can help the early diagnose and treatment of infectious keratitis. It is a noninvasive imaging technique that provides high resolution images of ocular structures at a cellular level and infectious keratitis represents one of its most important clinical uses.

Objective To investigate the expression of paired box2(Pax2),proliferation cell nuclear antigen(PCNA) and cell apoptosis in steroid-sensitive and steroid-resistant groups with primary nephrotic syndrome(PNS) and to find out the action of Pax2 expression in PNS with steroid-resistance.Method The expressions of Pax2,PCNA were evaluated by immunohistochemistry and cell apoptosis by fluorescence micoscope.Results Pax2 expression in renal tubule had a positive correlation with PCNA expression in steroid-sensitive group.In steroid-resistant group,Pax2 expression had no correlation with PCNA.Pax2 had a negative correlation with cell apoptosis.Conclusions Pax2 proper expression facilitate PCNA expression and repair tubulointerstitial lesions in steroid-sensitive group.Renal tubular epithelial cell proliferation coordinated with cell apoptosis.Pax2 overexpression in steroid-resistant group lead to the decrease of cell proliferation and cell apoptosis and lead to the severe tubule lesions,which made to glucocorticoid resistance.
