The mRNA levels of adiponectin in adipose tissue and adiponectin receptor R1 in skeletal muscle of type 2 diabetic rats were examined by semi-quatitative RT-PCR.The expression of adiponectin receptor R1 was not altered in the skeletal muscle of type 2 diabetic rats as compared with normal rats.The serum adiponectin level was decreased in diabetic rats due to the decline of adiponectin mRNA level in adipose tissue and rosiglitazone improved the adiponectin deficiency.

SW872 cells were cultured in vitro with oleic acid and differentiated into mature adipocytes. The role of interleukin-6(IL-6)in the secretion of acylation-stimulating protein(ASP)in mature SW872 adipocytes was observed.The results suggested that IL-6 significantly inhibited ASP secretion into the media in a dose-and time-dependent manner in mature SW872 adipocytes.

SW872 preadipocytes were cultured and induced to differentiate by oleic acid in vitro.The levels of adiponectin and its receptors (AdipoR1 and AdipoR2) mRNA were measured by semiquantitative RT- PCR.The concentration of adiponectin in the culture medium was assayed by ELISA.The results showed that rhIL- 6 could inhibit adiponectin,AdipoR1 mRNA expressions and adiponectin secretion in SW872 adipocytes in a time- and dose-dependent manner,but did not influence adipoR2 mRNA expression.

The level of serum soluble interleukin-2 receptor(sIL-2R)was measured in 103 patientswith hepatitis B and 26 hepatitis B virus(HBV)carriers by enzyme-linked assay.The sIL-2Rconcentration were elevated significantly in each type of hepatitis B patients and HBV carriers,compared with control group(P

·AIM:To investigate the surgical method and efficacy of extraction of deep orbital magnetic foreign bodies by mean of an orbital strong magnet.·METHODS: A retrospective analysis of clinical data of patients with deep orbital magnetic foreign bodies ( OMFB ) in Hebei Eye Hospital from June 2014 to May 2017 was processed. A total of 23 eyes were enrolled, among them, 14 eyes of extraorbital OMFB, 9 eyes of intraorbital OMFB. The rate of extraction of foreign bodies and the postoperative complications were observed.·RESULTS: All eyes of intraorbital foreign bodies were successfully extracted with 100% success rate. Twelve of 14 eyes of extraorbital foreign bodies were extracted with 86% success rate. Mild orbital hemorrhage were found in 2 eyes. There was no other obvious complication such as visual loss, orbital massive hemorrhage or limited ocular movement.·CONCLUSION: It's an ideal surgical method to extract the deep orbital magnetic foreign bodies by mean of an orbital strong magnet, with mini-injury, high success rate, short duration and few complications.

OBJECTIVETo investigate the differently expressed Homeobox genes between adenoid cystic carcinoma of salivary gland and normal gland tissue, and find out the effect of homeobox genes on oncogenesis and differentiation of adenoid cystic carcinoma of salivary gland.

METHODSSix strictly paired specimens including adenoid cystic carcinoma and its surrounding normal gland tissue and two pairs of specimens including cell strain of adenoid cystic carcinoma and its surrounding normal gland tissue were established. Customized Oligo microarray which contains probes of 232 human homeobox genes was used to analyze and conclude two groups of different genes data. RT-PCR technique was used to examine the mRNA expressing level of highly suspected relevant genes of adenoid cystic carcinoma in different specimens. Obvious differently expressed Homeobox genes were found through statistical analyses.

RESULTSIn tissue specimens homeobox genes were found 67 up-regulated and 54 down-regulated, and in cell specimens homeobox genes were found 12 up-regulated and 15 down-regulated. One up-regulated gene and 7 down-regulated genes were found both in tissue and cell specimens, among which EVX1 and PITX1 were the most frequent. RT-PCI showed that there was statistical expressing difference between TGIF, EVX1 and normal gland tissue in ACC-M.

CONCLUSIONAs the key gene to cellular proliferation and differentiation, homeobox genes are closely relevant to the oncogenesis of adenoid cystic carcinoma of salivary gland.

Growth suitability as assessment indicators for medicinal plants cultivation was proposed based on chemical quality determination and ecological factors analysis by Maxent and ArcGIS model. Notopterygium incisum, an endangered Chinese medicinal plant, was analyzed as a case, its potential distribution areas at different suitability grade and regionalization map were formulated based on growth suitability theory. The results showed that the most suitable habitats is Sichuan province, and more than 60% of the most suitable areawas located in the western Sichuan such as Aba and Ganzi prefectures for N. incisum. The results indicated that habitat altitude, average air temperature in September, and vegetation types were the dominant factors contributing to the grade of plant growth, precipitation and slope were the major factors contributing to notopterol accumulation in its underground parts, while isoimperatorin in its underground parts was negatively corelated with precipitation and slope of its habitat. However, slope as a factor influencing chemical components seemed to be a pseudo corelationship. Therefore, there were distinguishing differences between growth suitability and quality suitability for medicinal plants, which was helpful to further research and practice of cultivation regionalization, wild resource monitoring and large-scale cultivation of traditional Chinese medicine plants.

BACKGROUNDSpinocerebellar ataxia type 7 (SCA7) is known as an autosomal dominant cerebellar ataxia; patients with genetically confirmed diagnoses of SCA7 have increased rapidly in recent years. However, SCA7 is a rare subtype of SCA, and most data available about SCA7 are those of white people. The aim of the present study was to systematically review the prevalence and clinical and genetic aspects of SCA7 patients in East Asian population.

METHODSA search for publications on SCA7 was performed by using the "PubMed" database with the published language limited in English. Publications mainly focusing on the prevalence of SCA7 in patients with SCA and the clinical and genetic features of SCA7 patients were fully reviewed and analyzed.

RESULTSThe prevalence of SCA7 in SCA patients ranged from 0 to 7.7%, which was similar to those reported previously. The clinical manifestations were typically present at the 30's of its victims (median, 29 years; interquartile range (IQR), 19.5-36.5 years), and the symptoms appeared 15 years ((15.17+/-4.22) years) earlier on average in the offspring than in the parents. Gait ataxia and visual impairment were both found in all patients of whom the clinical features were described. Mutant SCA7 alleles contained 40-100 CAG repeats, with a median of 47 repeats (IQR, 44.5-50.0); and the offspring had 13 more repeats on average compared with their parents (12.62+/-19.03). A strong negative correlation was found between CAG repeat size and the onset age of patients (r=-0.739, P=0.000). In addition, no significant difference was found in CAG repeat sizes between patients with visual impairment as the initial symptom and those with gait disturbance as their initial symptom (P=0.476).

CONCLUSIONSThe prevalence of SCA7 in SCA patients, the age at onset and CAG repeats of SCA7 patients in East Asia are consistent with those of white people. However, larger population study is needed to assess the correlation between the CAG repeat size and initial symptoms of SCA7 patients in East Asia.

OBJECTIVETo study the role of serum from asphyxiated neonates in the inducement of human renal proximal tubular epithelial cells (HK-2) adhesion to neutrophils and possible mechanisms.

METHODSHK-2 cells were cultured randomly with 20% serum from neonates (1, 3, and 7 days after asphyxia), pyrrolidine dithiocarbamate (PDTC) or placebo. The activity of myeloperoxidase (MPO), an indicator of adhesion ability of HK-2 cells to neutrophils in suspensions, was detected by the biochemistry assay. Intercellular adhesion molecule-1 (ICAM-1) and nuclear factor-kappaB (NF-kappaB) of HK-2 cells were examined with the immunohistochemical staining.

RESULTSThe expression of MPO in the post-asphyxial 1-day serum treatment group were significantly higher than that in the PDTC treatment and the control groups as well as the post-asphyxial 3 and 7-day serum treatment groups (P<0.01). The expression of ICAM-1 and NF-kappaB in the post-asphyxial 1-day serum treatment group was also significantly higher than that in the other groups (P<0.01).

CONCLUSIONSSerum from asphyxiated neonates can induce HK-2 cell adhesion to neutrophils, possibly through activating NF-kappaB and increasing the synthesis and expression of ICAM-1 on the surface of renal tubular epithelial cells.
