Objective To investigate the iodine nutritional status of targeted population in the high-risk areas of iodine deficiency disorders in Chongqing, so as to provide scientific evidence for establishing prevention and remedial measures. Methods Six towns were selected in Chengkou and Wuxi Counties to found suspected dementia patients born after first Jan, 1997. Two hundred children aged 8-10 years were investigated in every town. The thyroid volume, intelligence quotient(IQ) and urinary iodine of the children were examined. Forty women (pregnant and nursing women) were investigated in every town. The iodine content of salt from their home was measured. The thyroid volume was examined by palpation and B-uhrasound. IQ was measured by combined Raven Test in China(CRT-RC2). Urinary iodine was determined using the acid digest arsenic-cerium contacting method, and iodined salt was detected using direct titration method. Results Six suspected dementia patients were found in the local town hospital. Five eases were excluded. There was 1 case born in other place. The rates of goiter by palpation and B-ultrasound were 9.58%(92/960) and 8.89%(65/731), respectively. The median of urinary iodine of children and women was 319.15 μg/L and 248.42 μg/L, respectively. The mean of IQ of the children was 103.32. The coverage rate of iodine salt from residents was 98.82%(336/340). Conclusions The iodine nutrition of children was good and there is no newly occurred cretinism in Chengkou and Wuxi Counties. Goiter rate and median of urinary iodine aged 8-10 years and of women, coverage rate of iodine salt from resident has meet the standard set for basical elimination iodine deficiency disorders.

We predicted the anti-hepatitis B virus (HBV) active components and mechanism of Salvia miltiorrhiza based on network pharmacology. The active components of S. miltiorrhiza were obtained through TCMSP, PubChem database and literature research. The potential targets of the active components and HBV infection were predicted by SwissTargetPrediction and GeneCards databases, respectively. The protein-protein interaction (PPI) network was constructed by String database. Cytoscape software was adopted to construct a visual network of active component-disease target and perform topological analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using DAVID platform. The molecular docking of key components and core targets was carried out by AutoDock Vina software. We screened out a total of 38 active components and 178 disease-component overlapping targets. Enrichment analyses obtained 405 related GO items and 68 signaling pathways, such as T/B cell receptor signaling pathways, PI3K/AKT signaling pathway, and mTOR signaling pathway. According to the results of molecular docking, most characteristic components of S. miltiorrhiza (miltionone Ⅱ, miltirone, protocatechuic acid, lithospermic acid, protocatechualdehyde) showed good affinity with the key targets (PIK3CA, APP, STAT3,AKT1 and mTOR). Furthermore, the anti-HBV activity of lithospermic acid, the representative active component of S. miltiorrhiza, and its regulation on PI3K/AKT and mTOR signaling pathways were investigated in an HBV replicating mouse model. Animal welfare and experimental procedures follow the regulations of the Animal Ethics and Welfare Committee of Hubei University. The results showed that lithospermic acid significantly inhibited HBV DNA replication, reduced serum HBsAg and HBeAg levels, and decreased the phosphorylation protein expression levels of AKT and mTOR in liver, indicating that lithospermic acid might exert the anti-HBV activity by regulating PI3K/AKT and mTOR signaling pathways.

OBJECTIVETo study differential expression profiles of ribosomal protein (RP) genes in healthy subjects and ulcerative colitis (UC) patients of Pi-asthenic syndrome (PAS) and of dampness-heat syndrome (DHS), thus providing experimental bases for " Pi as the source of qi and blood" theory from the view of protein synthesis.

METHODSRP genes arrays were made. The mucous membrane of colon was detected in four UC patients of PAS (UC-PAS), four UC patients of DHS (UC-DHS), and four healthy subjects (N), and data analyzed using BRB-TOOL Software Package (3.9). Bioinformatics analyses were conducted in differential genes.

RESULTSLow-density RP gene chips were successfully produced, including 77 RP genes and two RP like genes (RPL26-like1 and RPL7-like1). There were twelve differential genes between UC (PAS+DHS) and N, all of which were down-regulated genes. There were nineteen differential genes between UC-DHS and N, all of which showed down-regulating tendency. There were three differential genes between UC-PAS and N, all of which were down-regulated genes. There were six differential genes between UC-PAS and UC-DHS, all of which were up-regulated genes. Cluster analysis showed that normal and UC samples of this chip can be classified according to gene expression profiles, and UC-PAS and UC-DHS can be classified by clustering. Various differential genes had a common transcription regulatory factor.

CONCLUSIONSRP genes arrays were successfully produced. RP gene expressions were down-regulated in UC-PAS and UC-DHS. Corresponding gene expression profiles were shown in N, UC-PAS and UC-DHS.

Objective To investigate the effects of different standard cross sections and angles on the measurement accuracy of induced postnatal fetal long bones. Methods Fetal long bones (femori and humeri) in 30 cases with induced abortion were measured utilizing ultrasound from different angles and /or at different directions. The values measured from different sections and angles with vernier calipers were compared prenatally and postnatally. Results There was no apparent difference between the pre-induced abortion and those of the post-induced abortion. The results in the 30 cases showed that: (1) the values measured from anterior 90 degree, the long bone length would best match with the bare long bone length up to 96.7%, the match rate of other angles and/or directions was up to 80%; (2) no apparent statistical difference was between the length of left and right bone and no difference was found using 4 different directions and 3 different angles; (3)there was no difference between the left and right femuri and humeri.Conclusions Though the measured value from anterior 90 degree direction was the most accurate one, the statistical analtical results showed no difference among 12 values measured from 3 different angles and/or 4 different directions.

BACKGROUND:The intestine is not only the main target attacked by sepsis but also the vital organ which mediated sepsis. The recovery of the damaged intestinal barrier structure and function is related to the occurrence and outcome of multiple organ dysfunction syndrome (MODS). How to protect and reduce the damage of the intestinal mucosa and how to promote the reconstruction of the intestinal mucosa have been the important topics in sepsis for many years. This study aimed to investigate the influential factors of intestinal mucosal reconstruction after intestinal epithelial injuryin vivo in a mouse model of sepsis.METHODS:Mice were subjected to cecal ligation and puncture (CLP) for induction of sepsis to assess intestinal mucosal damage, epithelial cell apoptosis, and transformed number of goblet cells, and to detect the concentration of TNF-α, IL-1 and TGF-β1 and TFF3 (trefoil factor 3) expression in the small intestinal mucosa. All above were performed by HE staining, western blot, ELISA and immunohistochemistry respectively. The experimental animals were divided into a sepsis group and a sham-operation group. The animals with sepsis were separately killed at 6 (7 animals), 24 (7 animals) and 48 hours (7 animals) after CLP.RESULTS:Injured intestinal mucosa was observed in the 3 groups under a light microscope, in which damage scores in the 24-hour and 48-hour groups were higher than in the 6-hour group and no difference was found between the two groups. Moreover, less of goblet cells or other epithelial cells adjacent to the injured surface migrated into the wound to cover the denuded area. The number of goblet cells was substantially decreased in the three CLP groups compared with the sham-operation group. Protein levels of IL-1 and TNF-α were significantly increased by 3-4 fold at all time points when compared with the sham-operation group, and cleaved caspase-3 by 4 fold. Although TFF3 expression was modestly increased for 6 hours after the onset of CLP, it appeared to decline at 24 hours and 48 hours as shown by Western blot. A similar tendency was observed upon TGF-β1, i.e. the protein level was not elevated at 24 hours and 48 hours, but increased modestly at 6 hours.CONCLUSIONS:Sepsis from CLP shows less restitution on the surface of injured intestinal mucosa. There is evidence that both constant inflammatory reaction and epithelial cell apoptosis may affect mucosal reestablishment of the intestine at the onset of sepsis. Mucosa after severe sepsis showed the state of high inflammation, and declined goblet cell function and mucosal reconstruction, which affected the repair of damaged intestinal barrier. Constant inflammatory reaction, and declined goblet cell function and mucosal reconstruction ability may affect the reestablishment of intestinal mucosa at the onset of sepsis.
