OBJECTIVETo study the prevalence rate of upper respiratory tract group A Streptococcus (GAS) carriage in school-age children from Xinjiang Province.

METHODSA total of 478 children at age of 9-12 years from Tulufan City and Buerjin County of Xinjiang Province were enrolled by random cluster sampling. Throat swab cultures were performed once each season for the determination of presence of GAS.

RESULTSIn the 1 827 samples, 196 GAS strains were isolated, with a GAS carrier rate of 10.7%. The prevalence rate of GAS carrier in Tulufan City ranged from 3.7%-16.5% compared with 4.7%-21.4% in Buerjin County (P < 0.05). The prevalence rate of GAS carrier in winter is the highest, followed by in autumn, spring and summer in both regions. There were significant differences in the GAS carriage rate in autumn between the two regions. There were no significant differences in the GAS carriage rate between boys and girls. Of the 196 GAS strains, 133 from Han, 22 from Uygur and 41 from Hazakh children. There were significant differences in the prevalence rate of GAS carriage among children with different ethic groups.

CONCLUSIONSThe prevalence rate of GAS carriage is high in school-age children from Tulufan and Buerjin of Xinjiang Province. The GAS carrier rate is associated with the season and ethic group. The children from Buerjin County present a higher GAS carrier rate than those from Tulufan City.

A possible role of hepatocyte nuclear factor 1 (HNF1) or HNF3, a predominant trans-acting factors of hepatic or pancreatic beta-cells, was examined on the tissue specific interdependent expression of glucokinase (GK) in liver, H4IIE, HepG2, HIT-T15 and MIN6 cell line. The tissues or cell lines known to express GK showed abundant levels of HNF1 and HNF3 mRNA as observed in liver, H4IIE, HepG2, HIT-T15 and MIN6 cells, whereas they were not detected in brain, heart, NIH 3T3, HeLa cells. The promoter of glucokinase contains several HNF3 consensus sequences and are well conserved in human, mouse and rat. Transfection of the glucokinase promotor linked with luciferase reporter to liver or pancreatic beta cell lines showed high interacting activities with HNF1 and HNF3, whereas minimal activities were detected in the cells expressing very low levels of HNFs. The binding of HNF1 or HNF3 to the GK promoter genes was confirmed by electrophoretic mobility shift assay (EMSA). From these data, we propose that the expression of HNF1 and/or HNF3 may, in part, contribute to the tissue specific expression of GK.

Most ingested foreign bodies pass readily throughout intestinal tract if they reach the stomach. In some cases, foreign bodies may be impacted behind a luminal constriction but are rare in colon. Here, we report the case of a 59-year-old man who did laparoscopic anterior resection due to sigmoid colon cancer 2 years ago and ischemic colitis was repeated on the anastomosis site. He initially presented with symptoms of abdominal pain 3 months before and melena 1 day before admission. Abdomen computerized tomography showed a 3.2 cm segment of luminal narrowing of the proximal colon involving upstream foreign material stasis. Sigmoidoscopic approaches revealed near complete obstruction on the anal verge of 20 cm and scope passing failed. Balloon dilatations were done on the obstruction site four times all and a foreign body impacted above the obstruction site was removed by an alligator without any complications. The foreign body removed looks like plastic or a shell, about 20 mm in size.

This study aims to establish quality standards of Aleuritopteris Herba (AH), which could supply scientific evidence for the quality control of AH. The morphological and microscopic identification characters were reformulated. The tests of water content, total ash, acid-insoluble ash and ethanol-soluble extractives of AH were carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition, volume 1). The TLC method was established by using aleuritopesis A [2,19-diol（2β,4α）-16-enekaureniod] and reference herb as references. With preparation of aleuritopesis A[2,19-diol（2β,4α）-16-enekaureniod] reference substance, the content of aleuritopesis A in AH was determined by HPLC. As a result, the macroscopic identification, microscopic features and TLC methods were specific and simple. The water content, total ash, acid-insoluble ash and ethanol-soluble extractive and the content of aleuritopesis A of all samples varied in the ranges of 8.8%-10.9%, 7.6%-11.4%, 2.5%-4.2%, 9.3%-10.2% and 0.56%-0.71%, respectively. The improved quality standard can be used to evaluate and guarantee the quality of AH comprehensively.

PURPOSE: A previous study has demonstrated that colchicine abrogated intercellular adhesion molecule (ICAM)-1 and fibronectin expression in renal cells exposed to high glucose media, but the underlying mechanism was not clarified. This study was undertaken to elucidate whether it was attributed to the inhibitory effect of colchicine on locally-produced angiotensin II (AII) under diabetic conditions. METHODS: Rat mesangial cells and NRK-52E cells were cultured in media containing 5.6 mM glucose (NG), NG+10(-7) M AII (NG+AII), or 30 mM glucose (HG) with or without 10(-8) M colchicine (Col) and/or 10(-6) M L-158,809, an AII type 1 receptor blocker (ARB). ICAM-1 and fibronectin mRNA and protein expressions were determined by real-time PCR (RT-PCR) and Western blot, respectively. AII levels in conditioned media were determined by ELISA. RESULTS: AII levels in conditioned media were significantly higher in HG-stimulated mesangial cells and NRK-52E cells compared to NG cells (p<0.05). ICAM-1 and fibronectin mRNA and protein expression were significantly increased in renal cells exposed to HG media (p<0.05 or p<0.01), and these increases were significantly ameliorated by colchicine or ARB treatment (p<0.05). Colchicine and ARB also significantly attenuated AII-induced ICAM-1 and fibronectin expression (p<0.05). However, there was no additive inhibitory effect of colchicine and ARB on the increases in ICAM-1 and fibronectin expression. CONCLUSION: Colchicine abrogated increased ICAM-1 and fibronectin expression in renal cells under diabetic conditions, which is partly mediated by inhibiting HG-induced locally-produced AII. These findings provide a new renoprotective mechanism of colchicine in diabetic nephropathy in addition to its impact on leukocyte functions.

OBJECTIVETo investigate the distribution of abnormal hilit syndromes in traditional Uighur medicine (TUM) among human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) patients, and to find out the clinical characteristics of abnormal savda syndrome type HIV/AIDS patients.

METHODSBetween June and July in 2012, 307 eligible HIV/AIDS patients from in-patient department and out-patient clinics of Xinjiang Uighur Autonomous Region the Sixth People's Hospital in Urumqi were investigated. TUM syndrome differentiation was performed by a senior TUM physician. Each participant completed a Sign and Symptom Check-List for Persons Living with HIV/AIDS (SSC-HIV) questionnaire. Depression was evaluated by using Hamilton Rating Scale for Depression Questionnaire. Blood specimen was collected from each participant to test the levels of blood chemicals.

RESULTSOf 307 HIV/AIDS patients, 189 (61.6%) were abnormal savda syndrome type, 118 (38.4%) were non-abnormal-savda syndrome type. Mean CD4 counts of abnormal savda syndrome type patients was (227.61±192.93) cells/µL, and the prevalence of anemia, thrombocytopenia, and elevated cystatin C were 49.7%, 28.6%, and 44.7%, which were significantly higher than those in the non-abnormal-savda syndrome type patients (26.3%, 16.0% and 25.0%,P<0.05). In addition, depression (79.9%) and HIV/AIDS-related symptoms such as fatigue (42.3%), back aches (40.7%), lack of appetite (33.9%), night sweats (31.7%) were more common among abnormal savda syndrome patients (P<0.05).

CONCLUSIONAbnormal savda syndrome is the dominant syndrome among HIV/AIDS patients, and they present a more sever clinical manifestation.
