OBJECTIVETo study the effect of Zhusha Anshen pill, cinnabar, HgS, HgCl2 and MeHg on the gene expression of renal transporters in mice.

METHODHealthy male mice were given equivalent physiological saline, Zhusha Anshen pill (1.8 g · kg(-1), containing 0.17 g · kg(-1) of mercury), cinnabar (0.2 g · kg(-1), containing 1.7 g · kg(-1) of mercury), high dose cinnabar (2 g · kg(-1), containing 1.7 g · kg(-1) of mercury), HgS (0.2 g · kg(-1), containing 0.17 g · kg(-1) of mercury), HgCl2 (0.032 g · kg(-1), containing 0. 024 g · kg(-1) of mercury), MeHg (0.026 g · kg(-1), containing 0.024 g · kg(-1) of mercury), once daily, for 30 d, measuring body mass gain. 30 days later, the mice were sacrificed. The mercury accumulation in kidneys was detected with atomic fluorescence spectrometer. Expressions of Oat1, Oat2, Oat3, Mrp2, Mrp4, Urat1 were detected with RT-PCR.

RESULTCompared with the normal control group, a significant accumulation of Hg in kidney in HgCl2 and MeHg groups was observed (P <0.05), but these changes were not found in other groups. Compared with normal control group, mRNA expressions of Oat1 and Oat2 were evidently lower in HgCl2 and MeHg groups, but mRNA expressions of Mrp2 were apparently higher in HgCl2 group (P <0.05), mRNA expression of Mrp4 was significant higher in HgCl2 and MeHg groups, and mRNA expression of Urat1 was apparently lower in MeHg group.

CONCLUSIONHgCl2 and MeHg groups show significant difference from the normal group in mercury accumulation in kidneys and gene expression of kidney transporters, but with no difference between other groups and the normal group. Compared with HgCl2 and MeHg, cinnabar and its compounds could cause lower renal toxicity to mice.

Objective To investigate whether the release of fibroblast growth factor-1 ( FGF-1 ) was changed after inhibition of S100A13 gene (small hairpin RNA, shRNA)and serum-deprivation in human thyroid cancer cells (TT cells ). Methods The S100A13-shRNA pENTRTM/U6 entry vector was transfected into TT cells. The expression of S100A13 mRNA and protein was detected by immunoflurescence, real-time RT-PCR, and Western blot. Then TT cells were treated with S100A13 gene inhibition and serum-deprivation. The changes in release of FGF-1 were detected by indirect immunoflurescence, RT-PCR, and ELISA. Results S100A13 shRNA transfected TT cells (S100A13 RNAi cells)had a reduction of S100A13 gene and protein expression by 80%.Indirect immunofluorescence indicated FGF-1 was mostly localized in the cytoplasm and nucleus of TT cells in primary culture. When serum-deprivation stress was given to TT cells, FGF-1 in cytoplasm almost disappeared in the cells at 6 h. RT-PCR indicated that when serum-deprivation stress was given to TT cells the mRNA of FGF-1 was reduced. ELISA showed that with inhibition of S100A13, the release of FGF-1 was reduced (P＜0.05).Conclusion S100A13-shRNA pENTRTM/U6 entry vector transfected TT cells may inhibit the expression of S100A13 and reduce the release of FGF-1.

Objective To learn the prevalence and trends of Brucella disease in Ningxia, in order to provide scientific basis for effective control of the disease. Methods Data of Brucella cases reported through city network from 2004 to 2009 in Yinchuan city, Shizuishan city, Wuzhong city, Guyuan city and Zhongwei city of Ningxia were reviewed and retrospectively analyzed. The data included demographic characteristics, treatment conditions and medical history so on related information. Analytical indicators include reported incidence;with patients' gender, age, regional distribution, urban and rural distribution;become chronic and associated factors;distribution of the cases reporting unit and so on. Results From 2004 to 2009, Ningxia had reported 349 cases of Brucellosis, no deaths, the annual incidence rates reported were 0.017/10 million, 0.543/10 million, 0.151/101 (295/54);The proportion of 34- to 40-year-old age group was higher than other age groups(27.5%, 96/349);Occupational distribution of patients was mainly farmers and herdsmen(70.2% ,245/349), in regional distribution of the patients, the highest percentage was Wuzhong city(61.9%,216/349), followed by Yinchuan city(22.9%,80/349);The proportion of patients in rural areas(97.4% ,340/349) was higher than urban(2.6% ,9/349);the proportion of patients converted to chronic was 11.2% (39/349). With age, the chance of patients converted to chronic was in a decreasing trend(odds ratio was 0.966);cases reported by Centre for Disease Control and Prevention accounted for 74.8%(261/349), by hospital accounted for 25.2%(88/349). Conclusions The reported incidence of Brucellosis in Ningxia is in a rapid upward trend year by year, the patients is mainly young men, the rate of converted to chronic is higher and the ability of hospital in founding and reporting of the cases is weaker.Comprehensive measures should be taken to increase funding, strengthen monitoring, and continuously improve the level of awareness and diagnosis of medical personnel for further strengthen the prevention and control of Brucellosis.

Objective To summarize the epidemiological feature of plague cases oceuwed in China.Methods The epidemiological and clinical data from 1981 to 2006 year in China were analyzed with descriptive study method.Result Nine hundred and seveneteen human plague cases were diagnosed in 9 provinces(regions) from 1981 to 2006 years,105 cases died,the mortality rate being 11.45%,and they distributed in 69 counties (cities or banners).In Qinghai Province 108 cases were diagnosed,the mortality rate was 46.30%(50/108),the cases distributed in 17 counties(cities);137 cans in Guizhou,distributing in 2 counties(cities);517 cases in Yunnan,distributing in 26 counties(cities).Plague cases peaked separately in 1983,1990,1996 and 2000 years,they were 25,75,98 and 254 separately.The principal spreading ways were breathing flying particles,touching,skinning and eating marmot in Qinghai;750 cases were of bubonic plague,among whom 4 cases in Tibet died,the fatality rate was 0.53(4/750);121 cases were of pneumonic prague,among whom 65 cases died,was accounting for 53.72%(65/121);31 cases were of septieaemic plague,and 30 cases died(one cases was cured in Inner Mongolia),accounting for 96.77%(30/31).Others were brain plague,intestinal plague,tonsil plague and plague cellulites,which were cured.Conclusion From 1990,human plague epidemical scope and intensity is enlarging continuously compared with 1980-1990 and there is a trend of going up gradually in China.

Objective:To observe the effects of acupuncture on the characteristics of neuro-electrophysiological activity in hippocampal CA1 and CA3 areas of rats with post-traumatic stress disorder (PTSD).Methods:Fifty Sprague-Dawley (SD) rats were randomly divided into a blank group,a model group,a grasping group,a Western medicine group and an acupuncture group,with 10 rats in each group.Except for the blank group,rats in the other 4 groups all received the combined stress modeling method.Rats in the Western medicine group were intragastrically administrated with paroxetine hydrochloride,those in the acupuncture group received acupuncture intervention,those in the grasping group received grasping fixation,and those in the model group and the blank group did not receive any interventions.After 14 d of intervention,the interspike interval (ISI) and power spectral densities (PSD) were analyzed and mapped by in vivo multiple channels to record the neuron clusters discharge in the hippocampal CA1 and CA3 areas.Results:Compared with the blank group,ISI was prolonged in the CA1 and CA3 areas of the model group and the grasping group,and the concentrated PSD distribution area moved down (P＜0.05 or P＜0.01).Compared with the grasping group,the ISI of the CA1 and CA3 areas in the Western medicine group and the acupuncture group was shortened,and the concentrated PSD distribution area moved up (P＜0.05 or P＜0.01).The ISI and PSD distributions in the CA1 and CA3 areas of the acupuncture group were not statistically different from those in the Western medicine group (both P＞0.05).Conclusion:Both acupuncture and paroxetine hydrochloride can significantly regulate the neuro-electrophysiology activity of hippocampal CA1 and CA3 areas in PTSD rats,which may be one of the mechanisms of acupuncture intervention to promote PTSD recovery.
