Objective To study the effect of acupuncture Zusanli on brain functional magnetic resonance imaging.Methods 96 healthy volunteers were randomly divided into acupoint group and non-acupoint group.The acupoint group received acupuncture Zusanli,and the non-acupoint group received manipulation,acupuncture and sham acupuncture.The functional brain imaging was determined by MRI,the brain functional images were compared between two groups.Results All subjects were matched with the end of the experiment,the acupoint group received acupoint stimulation,had obvious needling sensation,the non-acupoint group had mild needling sensation.The acupoint group activated 13 brain regions,non-acupoint group in 10 brain regions,the thalamus,pons,supramarginal gyrus in non-acupoint group without the activation.In the basal ganglia (28 cases vs.5cases) and temporal lobe (38cases vs.21cases) between the two groups were activated,the difference was statistically significant(x2 =36.250,P ＜ 0.05).In the temporal lobe,the left hemisphere response rate(73.68％) was significantly higher than the right hemisphere (36.84％),the difference was statistically significant (x2 =8.265,P ＜ 0.05).In the basal ganglia,left hemisphere activation (67.86％) was higher than that of the right hemisphere(42.86％),but the difference was not statistically significant (x2 =0.724,P ＞ 0.05).Conclusion The research of acupuncture by brain functional magnetic resonance imaging showed that Zusanli acupoint can activate the brain function area through brain regulation and treatment of body organs,so as to prove the existence of its own and meridian sensing characteristics.

To investigate the changes of plasma adrenomedullin(ADM) and adrenotensin(ADT) levels and their clinical significance in the pathological process of congestive heart failure(CHF), plasma levels of ADM and ADT in 45 patients with CHF before and after treatment were measured by specific radioimmunoassay. The results indicated that before treatment, plasma levels of ADM in class Ⅱ and Ⅲ CHF patients were 51.46?4.52pg/ml, 70.39?3.22pg/ml and plasma levels of ADT in class Ⅱ and Ⅲ CHF patients were 29.98?1.13pg/ml, 33.45?0.91pg/ml, respectively,which were higher than those of the control subjects(24.12?1.59pg/ml and 24.89?2.19pg/ml, respectively)(P

Objective To learn quality of life of acute upper respiratory tract infection patients and their influence factors.Methods We conducted questionnaire investigation on acute upper respiratory tract infection patients from five hospitals,respectively located in Wuhan,Hefei and Jinhua.The scale we used is EQ-5D.We calculated EQ-5D score through three different integration systems,which are from China,Korea and the UK,in order to compare difference among different countries' integration systems.Then econometric model was used to carry out regression analysis on factors affected EQ-5D score.Results 659 samples was included,with 319 from Wuhan,235 from Hefei and 105 from Jinhua.Among EQ-5D five dimensions,the first three dimensions do not have problems.However,81.94％ of the patients have problems in pain/discomfort and 47.8％ of them have problems in anxiety/depression.In regression analysis,location,severity level of disease and whether accompanied by chronic diseases or not have influence on EQ-5D score.Compared with utilities of patients who are suffered from other diseases,utilities of acute upper respiratory tract infection patients are lower than that of cerebral apoplexy,hypertension,coronary heart diseaseand diabetes patients;but are higher than that of Chronic lymphatic filariasis,chronic obstructive pneumonia and rheumatoid arthritis patients.Conclusion Chinese acute upper respiratory tract infection patients mainly have problems in the dimension of pain/discomfort and anxiety/depression.Compared to British integration system,Korean's is more applicable to Chinese population.Acute upper respiratory tract infection patients' utilities are lower than that of healthy population and chronic invalids with no obvious symptoms,and higher than that of chronic invalids with obvious symptoms.

Objective:To study the role of angiopoietin-2(Ang-2) in angiogenesis in oral squamous cell cacinoma(OSCC). Methods:Expression of angiopoietin-2 and CD_34 in 41 cases of OSCC(13 cases with lymph node metastasis)and 10 cases of normal oral mucosa was detected by immunohistochemical SABC method. Microvessel density(MVD) in the samples was counted under microscope. Results:Ang-2 was detected in 28 out of 41(68.29%) cases of OSCC and 2 out of 10(20%) of normal oral mucosa(P

BACKGROUND: Liver fibrosis has higher morbidity and mortality. Activation and proliferation of hepatic stellate cells is a key link in the progression of liver fibrosis. At present, there are still no effective anti-fibrosis agents targeting single links or targets. OBJECTIVE: To analyze the effect of human adipose stem cells derived exosomes on rats with liver fibrosis induced by carbon tetrachloride. METHODS: Human adipose stem cells were obtained from healthy people by enzyme dissolution method. After in vitro culture, human adipose stem cells derived exosomes were obtained by multiple ultrafiltration. Different concentrations of exosomes were used to treat the hepatic stellate cells activated by transforming growth factor β1. The human adipose stem cells activated by transforming growth factor β1 were treated with different concentrations of exosomes. The expression of α-smooth actin in the cells was detected by quantitative PCR, and the growth and apoptosis of activated hepatic stellate cells were detected by CCK-8 and flow cytometry respectively. Rat models of liver fibrosis were established by intraperitoneal injection of carbon tetrachloride and treated by tail vein injection of exosomes. Rat liver function, serum levels of type III procollagen and type IV collagen, and Ishak score were determined. Semi-quantitative analysis of liver fibrosis was performed. The expression levels of tissue inhibitor of matrix metalloproteinase-1, matrix metalloproteinase 9 and α-smooth actin in liver tissue were measured by immunofluorescence method. The study protocol was approved by the Animal Ethics Committee and Medical Ethics Committee, Tongji University, China in January, 2017. RESULTS AND CONCLUSION: Human adipose stem cells derived exosomes inhibited the proliferation of activated hepatic stellate cells. The possible mechanism is to inhibit the proliferation of activated macrophages, reduce the production of collagen fibers, α-smooth actin actin, and tissue inhibitor of matrix metalloproteinase-1, and to increase the expression of matrix metalloproteinase 9. These findings suggest that exosomes can be used to treat carbon tetrachloride induced liver fibrosis.

Objectives To study the changes of plasma levels of proadrenomedullin N terminal peptide(PAMP) in patients with congestive heart faillure(CHF) before and after drug treatment and its significance.Methods Plasma PAMP levels in 45 patients with CHF and 7 heathy control subjects were measured by specific radioimmunoassy.Results The plasma PAMP levels in patients with CHF were significantly decreased with the deterioration of cardiac function.Plasma PAMP levels in 45 patients in NYHA class Ⅳ(2 79?0 89pg/mL) were significantly lower than those in class Ⅱ(6 24?1 71pg/mL)?class Ⅲ(7 38?1 28pg/mL) and control subjects(8 56?2 44pg/mL)(P

Objective: To investigate the correlation of thrombospondin-1(TSP-1) expression and angiogenesis and clinical pathologic factors in breast cancer. Methods:Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expression of TSP-1 mRNA in the primary breast cancer tissues and the tissues set apart 5 cm from the tumor. Im-munohistochemistry was used to detect the expressions of vascular endothelial growth factor (VEGF), c-erbB2, estrogen receptor (ER), progesterone receptor (PR) and microvessel density (MVD). All data were statistically analyzed. Results: The positive rate of TSP-1 was significantly higher in breast cancer than that in tissues set apart 5 cm from tumor (P < 0.05). The expression of TSP-1 was positively correlated with tumor size only (P < 0.05). MVD was lower in TSP-1 positive group than that of negative group (P< 0.05). Conclusion: The MVD was decreased with up-regulation of TSP-1 expression. Thrombospondin-1 may repress the angiogenesis in breast cancer.
