In order to remove invasive plasmids from Shigella flexneri 2a 2457T and Shigella sonnei S7 based on the principle of plasmid incompatibility Ori and inc genes were amplified by PCR from S. flexneri 2a invasive plasmids, and then they were cloned into plasmid pMD18 T, resulting recombinant plasmids pMDori and pMDinc After S flexneri 2a 2457T and S sonnei S7 were transformed with pMDori or pMDinc respectively Invasive plasmids were removed from S flexneri 2a 2457T and S sonnei S7

OBJECTIVETo investigate the association between the polymorphism of vitamin D receptor (VDR) gene start codon (Fok I) and bone mass accrual, and assessing if such an association could be modified by physical activity in Chinese adolescent girls.

METHODSA total of 228 premenrche Chinese girls (9-11.5-years-old) were recruited for 2-year study. Bone mineral densities (BMD) at the total body, total left hip (including femoral neck, trochanter, intertrochanteric and Ward's triangle area) and lumbar spine (L1-L4) were measured by dual energy X-ray absorptiometry. The Fok I polymorphism of VDR gene was detected with PCR-RFLP.

RESULTSThere remained 176 available subjects in our cohort when 2-year study was completed. No significant association was observed between Fok I polymorphism of VDR gene and percentage change in BMD at all sites. Girls with FF genotype had lower percentage change in total left hip BMD (THBMD) and femoral neck BMD (FNBMD) than girls with Ff + ff genotype only in low physical activity(< 1197 kJ/d), and physical activity was associated with percentage change in THBMD and FNBMD only in FF genotype group.

CONCLUSIONThe Fok I polymorphism of VDR gene should have significant interaction effect with physical activity on bone mass accrual in Chinese adolescent girls. Girls with FF genotype in low physical activity would be the potential risk population for low bone mass accrual, and high physical activity would be of benefit to gain higher bone mass accrual for girls with FF genotype.

OBJECTIVE: To investigate the diagnostic significance of basophil activation test (BAT) in anaphylaxis to non-ionic contrast media through testing the content of CD63, mast cell-carboxypeptidase A3 (MC-CPA3), and terminal complement complex SC5b-9 of the individuals by testing their levels in the normal immune group and the anaphylaxis groups to β-lactam drugs and non -ionic contrast media. METHODS: The CD63 expression of basophilic granulocyte in blood was detected by flow cytometry. The levels of MC-CPA3 in blood serum and SC5b-9 in blood plasma were detected by ELISA. RESULTS: The CD63 expression of basophilic granulocyte in blood, the levels of MC-CPA3 and SC5b-9 of anaphylaxis to non-ionic contrast media and β-lactam drugs were significantly higher than that in normal immune group (P < 0.05). CONCLUSION There is activation of basophilic granulocytes, mast cells and complement system in anaphylaxis to non-ionic contrast media. BAT can be used to diagnose the anaphylaxis to non-ionic contrast media.

OBJECTIVETo explore the possible factors causing the increase of rabies cases and to provide references for the development of related prevention and control strategy in Hunan.

METHODSData was collected and analyzed on epidemic situation of rabies in the past ten years, and studies were carried in some counties.

RESULTSFrom 1994 to 1999, the annual cases sustained between 17 and 78. However, the number of cases has continued to increase since 2000. The annual reported cases in 2001 and 2002 were 311 and 313, and accounted for 34.8% and 30.0% of the total cases in the whole country respectively. The epidemic areas were mainly located in the south and middle parts of Hunan. Furthermore, the epidemic areas had been expanding. In 1997, human rabies cases were only reported in 7 cities but increased to 12 cities in 2004.

CONCLUSIONFactors as increasing number but low inoculating rate to dogs, and incorrect treatment on the wounds etc. might have served important roles for the recurrence of rabies. Hence, it is necessary to take comprehensive preventive measures to control and prevent the epidemics of rabies in Hunan.

OBJECTIVETo investigate the effect of interleukin-6 (IL-6) and calcium sensing receptor (CASR) gene polymorphisms on bone mass accrual in Chinese adolescent girls.

METHODSA total of 228 premenarche Chinese girls (9-11.5 years) were recruited for a 2-year study. Bone mineral densities (BMD) and Bone mineral contents (BMC) in the total body, total left hip including femoral neck, trochanter, intertrochanter and Ward's triangle area, and lumbar spine (L1-L4) were measured by DEXA. The -634C/G polymorphism of IL-6 gene was detected by PCR-restriction fragment length polymorphism and A986S polymorphism of CASR gene was detected by allele-special mutagenically separated amplication-PCR.

RESULTSThere were 176 available subjects when the 2-year study was completed. The -634C/G polymorphism of IL-6 gene and A986S polymorphism of CASR gene were significantly associated with bone mass accrual after adjusting the potential confounding factors. Girls with CC genotype of IL-6 -634G/C gene had higher percentage of increase in BMD of total body (P= 0.027) and femoral trochanter (P= 0.028) than those with CG+ GG genotypes. Girls with AA genotype of CASR gene had greater percentage of increase in L1-L4 lumbar spine BMC (P= 0.022) and Ward's triangle area BMD (P= 0.049) than their AS+ SS counterparts. Subjects with G allele of IL-6 gene in combination with S allele of CASR gene had less increase in BMC of femoral neck and L1-L4 lumbar spine.

CONCLUSIONAdolescent girls carrying the G allele of IL-6 gene at -634C/G and S allele of CASR gene at A986S could potentially be the risk population of lower bone mass accrual.

OBJECTIVETo observe the effect of acupuncture at the whole points of Hand Jueyin pericardium meridian on the amplitude of low frequency fluctuations (ALFF) of healthy people in resting state (R1) functional magnetic resonance imaging (fMRI).

METHODSTotally 16 healthy subjects received structure scan of T1 and T2. Then two fMRI scans were conducted for each participant. fMRI included the resting-state scan (R1; the scanning time was 8 min 6 s), the stimulating-acupoint scan (AP; the scanning time was 8 min 6 s). fMRI data acquisition from structure scanning and function scanning were processed with format conversion and statistical analysis.

RESULTSUnder R1 state, brain regions with activated ALFF signals included bilateral superior frontal gyrus, medial frontal gyrus, middle occipital gyrus, precuneus, superior temporal gyrus, and cingulate gyrus. Under the AP state, brain regions with activated ALFF signals were bilateral superior frontal gyrus, medial frontal gyrus, middle temporal gyrus, left fusiform gyrus, precuneus, posterior cingulate, and declivis. Compared with R1 state, obvious difference of ALFF signal areas of the brain caused by acupuncture at pericardium were: bilateral cuneus, precuneus, left posterior cingulate gyrus, right middle occipital gyrus, and right occipital lingual gyrus.

CONCLUSIONAcupuncture at the whole points of Hand Jueyin pericardium meridian could significantly change inherent activity states of the cerebral cortex, especially in bilateral superior frontal gyrus, medial frontal gyrus, and precuneus.

OBJECTIVETo observe amplitude changes of low frequency fluctuation in brain spontaneous nervous activities induced by needling at Hand Taiyin Lung Channel, and to preliminarily explore the possible brain function network of Hand Taiyin Lung Channel.

METHODSBy using functional magnetic resonance imaging (fMRI), 16 healthy volunteers underwent resting-state scanning (R1) and scanning with retained acupuncture at Hand Taiyin Lung Channel (acupuncture, AP). Data of fMRI collected were statistically calculated using amplitude of low frequency fluctuations (ALFF).

RESULTSUnder R1 significantly enhanced ALFF occurred in right precuneus, left inferior parietal lobule, bilateral superior temporal gyrus, bilateral middle frontal gyrus, left superior frontal gyrus, left inferior frontal gyrus, left medial frontal gyrus. Under AP significantly enhanced ALFF occurred in right precuneus, bilateral superior frontal gyrus, cerebellum, bilateral middle frontal gyrus, right medial frontal gyrus, and so on. Compared with R1, needing at Hand Taiyin Lung Channel could significantly enhance ALFF in right gyrus subcallosum and right inferior frontal gyrus. Significant decreased ALFF appeared in right postcentral gyrus, left precuneus, left superior temporal gyrus, left middle temporal gyrus, and so on.

CONCLUSIONNeeding at Hand Taiyin Lung Channel could significantly change fixed activities of cerebral cortex, especially in right subcallosal gyrus, right inferior frontal gyrus, and so on.
