Objective To investigate the effect of acupuncture at Sanyinjiao with functional magnetic reso- nance imaging(fMRI),analyse the regulating effect of the acupoint Sanyinjiao on various brain areas,explore the mechanisms of Sanyinjiao(SP.6) acupuncture in treating diseases.Methods Eight right-handed healthy volun- teers were scanned at 1.5 Tesla magnetic resonance imaging scanner while they were aeupunctured at the right Sany- injiao acupoint.Image data were co-registered to correct head motion,spatial normalization and deconverlution analy- sis were conducted.Functional activation maps were generated.Results There observed certain activation in both sides of medial frontal gyrus,right middle frontal gyrus,left inferior frontal gyrus,both sides of paracentral lobule, precentral gyrus and postcentral gyrus,left inferior parietal lobule,both sides of preeuneus,right middle temporal gy- rus,right cingulated gyrus,posterior cingulated gyrus,both sides of superior temporal gyrus,transverse temporal gy- rus,insula and thalamus.Conclusion Acupuncturing the Sanyinjiao can lead to the functional changes in parietal lobe,frontal lobe,temporal lobe and insula,precuneus,cingulated gyrus,thalamus,which are closely related to the therapeutical effects of Sanyinjiao.The phenomenon that needling Sanyinjiao can activate certain brain areas proved the correlation between acupoint and corresponding brain cortices.

In this paper, the number of rhizosphere and non-rhizosphere microbial organisms of fusarium wilt resistant and susceptible watermelon under soil culture and soilless substrate culture was studied by traditional culture methods. The results showed that, the number of rhizoshpere microorganisms was significantly higher than non-rhizosphere, and the number was changed with the stage of watermelon grow, the number was the lowest in seedling stage and increased with the watermelon grow, and achieved highest at the flowering and fruiting stage, decreased with the watermelon ageing. The fusarium wilt resistant of watermelon was correspondence with number of rhizosphere bacteria; the number of rhizosphere bacteria of resistant watermelon was higher than that of susceptible watermelon in each stage under soil culture and soilless culture. The fusarium wilt resistant of watermelon is no correspondence with number of rhizosphere fungi and actinomycete. The number of non-rhizosphere microbial organisms was changed in a small range in the whole growing stage. The non-rhizosphere bacteria have no significant change in the whole stage under soil culture and increased quickly under soilless substrate culture and decreased at the later stage. The non-rhizosphere fungi and actinomycete reached highest at the later stage under soil culture or soilless sub-strate culture.

The traditional culture methods and the molecular biology methods were used to study the rhizosphere bacterial diversity between fusarium wilt resistant and susceptible watermelon. The results showed that the diversity and the equality of cultured rhizosphere bacteria of resistant watermelon were higher than those of the susceptible watermelon. The reason was that the cultured rhizosphere bacterial di- versity index H′ and 1/D of the resistant watermelon were higher than those of the susceptible watermelon and that the cultured rhizosphere bacterial equality index E of the resistant watermelon were higher than those of the susceptible watermelon. The dominant cultured bacterial genotypes were different between re- sistant and susceptible watermelon. The genotype 1 is the dominant genotype of resistant watermelon, con- sists 51.1%. The genotype 7 is the dominant genotype of susceptible watermelon, consists 58.7%.

Objective To investigate the clinical value of virtual touch tissues quantification in the evaluation of kidney stiffness in patients of diabetic nephropathy .Methods A total of 90 cases of diabetic nephropathy were divided into 3 groups:infinitesimal albuminuria ,microalbuminuria and massive proteinuria groups.And other 30 health subjects were taken as control group.The shears wave velocity ( Vs) which reflected the tissue elasticity was measured.The Vs values were compared among different groups.Results In all groups,the highest Vs was present in renal cortex .And compared with the renal cortex ,the Vs of the renal medulla and renal sinus have statistically significant differences [ the normal control group:( 3.65 ± 0.26)m/s,(2.72 ±0.35) m/s,(1.83 ±0.54) m/s,t =9.30,18.20,both P <0.05;Infinitesimal albuminuria group:(2.98 ±0.28)m/s,(2.47 ±0.33)m/s,(1.65 ±0.31)m/s,t=5.97,15.57,both P<0.05;microalbuminuria group:(2.55 ±0.22) m/s,(2.22 ±0.28) m/s,(1.54 ±0.21) m/s,t =3.86, 11.83,both P<0.05;massive proteinuria group:(1.99 ±0.28)m/s,(1.49 ±0.30)m/s,(1.01 ±0.39)m/s, t=5.85,11.48,both P<0.05].The renal cortex Vs of Infinitesimal albumonuria group ,microalbuminuria group and massive proteinuria group show a gradually decreasing trend .And the renal cortex Vs of microalbuminuria group and massive proteinuria group have statistically significant differences compared with the normal control group(t=11.79,17.79,both P<0.05).Conclusions Virtual touch tissues quantification technique can reflect the renal tissue elasticity .It will contribute to the assessment of renal function in patients with early diabetic nephropathy .

OBJECTIVETo investigate occupational health status of female workers in pharmaceutical industries and to propose the protective measures for the occupational health.

METHODA total of 2816 female workers from 19 pharmaceutical industries in Shandong and Gansu provinces were investigated by a questionnaire.

RESULTS73.1% of female workers exposed to occupational hazards, mainly to toxic chemicals. 63.2% of them suffered from dysmenorrhea; 38.5% of them have reproductive system diseases, i.e. mammary gland hyperplasia (44.1%), cervical erosion (26.5%), uterine annex inflammation (24.2%); 17.1% of them suffered from accidental work injuries; 34.7% of them complained about low back pain, and 29.7% of them perceived hearing loss. 94.9% of female workers hoped to get the occupational health and labor protection knowledge and skills.

CONCLUSIONStrengthening the supervision of labor protection for female workers, including technical measures occupational hazards control and health-related knowledge, and improving the occupational health status of female workers should be conducted.

Objective:To detect the expression of six miRNAs for miR-146a,miR-224,miR-34c,miR-200a,miR-148b,miR-375 level in primary hepatocellular carcinoma patients tissues and serum,and to explore the correlation between the expression of miRNA and inflammatory factors,in the hope of verification whether circulating miRNA could be used as an ideal blood borne biomarker for early detection of primary liver cancer.Methods:Venous blood samples were collected from patients with primary liver cancer,hepatitis,cirrhosis and healthy controls,cancer tissues and para cancerous tissues were collected from patients with cancer.After the total RNA was extracted,the relative expression levels of miRNA were detected by real-time quantitative PCR,and the relationship between the expression level of miRNA and the expression of serum tumor markers AFP,CEA,CA19-9 and CA125 was detected.The correlation between the expression level of miRNAs and the expression of HBsAg,anti-HBs,HBeAg,anti-HBe,anti-HBc and inflammatory factors IL-12,IL-4,IL-6,IL-10,IFN-γ,TNF-α was detected as well.Results:Compared with the healthy group,the expression of miR-34c,miR-224 and miR-146a in serum and tissues of PHC group was significantly up-regulated,and the expression of miR-200a,miR-148b and miR-375 in serum and tissues of PHC group was significantly down regulated.The difference was statistically significant.There was a regression relationship between HBsAg and serum miR-375 and miR-146a,and miR-375 decreased with the increase of HBsAg expression,while miR-146a increased with the increase of HBsAg.There was a regression relationship between IFN-γ and miR-146a,miR-146a increased with the decrease of IFN-γ expression.The diagnostic ability of miR-375 and miR-146a was greater than that of CA19-9 and AFP.Conclusion:MiR-146a,miR-224,miR-34c,miR-200a,miR-148b,miR-375 in serum and tissue of primary hepatocellular carcinoma are differentially express,among them,the diagnostic ability of miR-375 and miR-146a is better than that of AFP and CA19-9,and serum miR-375 and miR-146a may be the new markers for early diagnosis of PHC.
