Objective To evaluate the relationship between children interleukin-1 receptor antagonist gene(IL-1RN) polymorphisms and susceptibility to febrile seizures(FS).Methods Matching case-control study was carried out,blood samples from 52 patients with FS and 53 healthy children were collected.Genomic DNA was extracted and examined by polymerase chain reaction(PCR) amplification for judging IL-1RN genetype.Results Only Ⅰ/Ⅰ,Ⅰ/Ⅱ,Ⅱ/Ⅳ genetypes of IL-1RN were found in the surveyed Chinese population of Han nationality in Guangdong Province.No significant differences of these genotypes were observed in patients and controls.But the allele frequencise of Ⅰ,Ⅱand Ⅳ in patients were 95.2%,3.8% and 1.0%,respectively,while these frequencise in controls were 84.9%,10.4% and 4.7%,respectively.The allele frequency of IL-1RNⅠin patients was obviously higher than that in controls(P

OBJECTIVE:
To investigate Insertion/Deletion (InDel) polymorphism on the X chromosome and to screen 18 InDel loci for the Chinese Han population as a forensic DNA typing system auxiliary.
METHODS:
Eighteen X-InDel markers were selected using the Human Genome Browser and dbSNP database. Multiplex PCR primer pairs of selected X-InDel markers were designed using Primer 3 software and divided into 3 groups according to the amplified fragment length, labeled by FAM, HEX and TAMRA fluorescence dye, respectively. The population genetics research and comparative analysis of Chinese Han nationality and 4 main minorities, the Hui, Wei, Mongol, and Tibetan nationalities, were investigated with the system.
RESULTS:
A new multiplex genotyping system, named InDel X-18PLEX, was successfully developed and validated, consisted of 18 X-InDel markers on the X chromosome and 1 Amelogenin gender marker. No deviation from Hardy-Weinberg equilibrium expectations was detected in the distribution of genotypes in the 5 investigated ethnic groups. However, there was significant difference between their distributions. From the investigation of Han nationality, high female (0.9999994) and male (0.999 88) overall discrimination power values were obtained, as well as high overall mean exclusion chance values in trios (0.999 992) and in duos (0.99).
CONCLUSION
InDel X-18PLEX meets the requirements as a forensic DNA complementary kit, providing effective supplementary analytical tools for difficult cases.

5.The association of hippocampal glutamate with depression and the effects on gastric mobility.
Chinese Journal of Applied Physiology 2009;25(2):196-201
AIMTo explore the relationship between the pathology of depression and glutamate (Glu) in hippocampus, and the effect on gastric mobility.
METHODSDepression model was established by using the chronic unpredicted mild stress (CUMS). And stereotaxic and intra-hippocampal microinjection were also used in this experiment. Rat emotion and behaviors were observed by the change in body weight, sucrose preference-test, open field-test and forced swimming-test. Intragastric pressure and mobility were recorded with the instrument of Powerlab/8sp.
RESULTSCompared with the control, 21-day CUMS significantly reduced the increase in body weight, rat sucrose preference, locomotor activity and rearing in open field test, while it significantly increased duration of immobility time in forced swimming test. Meanwhile, magnitudes of intragastric pressure and mobility were significantly declined after 21 days CUMS. Microinjection of Glu into hippocampus mimics the behaviors which were produced in CUMS. The down-rang of gastric mobility in the group of Glu injection was smaller than CUMS, but was much larger than the control. Intrahippocampal microinjection of MK-801 attenuated depression-like behaviors induced by stress, weakened stress-induced inhibition of intragastric pressure, and augmented the magnitudes of gastric contraction.
CONCLUSIONGlu and NMDA receptor in hippocampus are to do much with the etiology of stress- induced depression. They are not only concerned with behavioral changes induced by stress, but also with the variation of gastric activities, nevertheless, differences exist between the effects of behaviors and gastric activities.

The paper is about the systematic studies of biological characteristics of 15 stains rhizobia isolated purified from Acacia confusa grew in Guangxi karst environment.The results showed that there were typical characteristics of rhizobia.there were negative reaction about use of 3-ketolactose and beef extract peptone nutrient agar medium,and positive reaction about use of starch and citrate medium,and produce acid in reaction of BTB and litmus milk medium,(NH4)2HPO4 was used as nitrogen sources and both four monosaccharides and three disaccharides could be utilized as carbon sources in 15 strains rhizobia isolated Acacia confuse.Among the 15 strains for the tests,11 strains could deoxidize the nitrate of medium into nitrite,14 strains could grow well on NaCl solution concentration 3.0 %~4.0 %,14 strains could grow at 39℃,13 strains may grow on highest pH12 and 4 strains on lowest pH4 cultrue medium.15 strains can grow in 10% and 11 strains in 10%~30% of CaCO3 solution concentration.

pH, affects of different alkaline materials KOH, K 2CO 3, NaOH, Na 2CO 3 on the growth, and NaCl, KCl tolerance of 29 isolates from the saline and alkaline soils in Xinjiang and Qinghai Provinces of China and 1 type strain were studied. Results showed that only a few alkaliphilic actinomycetes were Na +-obligately dependent, and K +-sensitive. Some alkaliphilic actinomycetes were CO 3 2- -sensitive, and NaCl, KCl could inhibit their growth. 4 kinds of alkaline materials had no affect on growth of alkaliphilic Nocardiopsis, and these strains showed high tolerance to NaCl, KCl. So it was presumed that only K + and CO 3 2- obligately dependent alkaliphilic Actinomycetes maybe exist in alkaline environments.

Objective To investigate the expression and significance of Caspase-3 and Survivin at different stages of human hemangioma in children.Methods Fifty-five specimens of hemangioma tissue excised in operation and 8 normal skins removed in operation were harvested from People's Hospital of Gansu Province between Jan.2000 and Dec.2005.The pathologic diagnosis was divided into 3 groups according to Mulliken's standard under microscope:proliferated phase group(n=31),degenerated phase group(n=24),and control group(n=8).All these specimens were examined by immunohisto for Caspase-3 and Survivin expression.Results Caspase-3 positive rate in the proliferative phase and involuting phase were 35.5% and 79.2%,respectively.The positive rate in involuting phase was higher than that that in proliferative phase,the difference between the 2 groups was significant(P=0.045 9).A significant difference was not found between the proliferative phase and normal skin tissue(P=0.057 3).Survivin positive rate in the proliferating and involuting phase were 77.4% and 45.8%,respectively.The positive rate in proliferative phase was higher than that in involuting phase,the difference between the 2 groups was significant(P=0.008 5),the difference in involuting phase and normal skin tissue was not significant(P=0.059 3).Conclusions High level of Caspase-3 expression in vascular endothelial cells in involuting phase in contrast to that in proliferative phase,which indicates that Caspase-3 may play a positive role in the apoptosis of vascular endothelial cells.Survivin may inhibit the apoptosis of vascular endothelial cells in proliferative phase due to it's high expression.Caspase-3 and Surivivin involved in the hemangioma in the regulation of apoptosis.J Appl Clin Pediatr,2009,24(1):51-52
