Literatures of study on acupoint functional effect of encephalic region with functional magnetic resonance imaging (fMRI) are collected from the database of China National Knowledge Information (CNKI) and Wan fang database. Analysis and comments are made respectively from the status quo of studies on combination of single acupoint, two acupoints and multiple acupoints under both physiological and pathological conditions. The results show that the corresponding encephalic regions can be specifically activated by acupuncture. And different regions can be activated by different acupoints. However, studies on single acupoint, two acupoints and three acupoints are the major researches carried out at present. It is still lack of observation on effect of commonly-used combinations in clinic. Moreover, the reliability of the research results are also affected by disunity of operations protocol, reinforcing or reducing manipulations, intensity or depth of stimulation and duration of needling retention. Therefore, it is necessary to establish a unified and standard operation protocol to strictly control the bias factors which may affect the result of research in the future, and take patients as the study target as much as possible, so as to further explore the central effect mechanism.

Objective To study the selective tumoricidal effect of adenovirus (Ad)-mediated fusion gene system driven by kinase domain-containing (KDR) promoter on human stomach adenocarcinoma SCG7901 cells, and to observe its apoptosis induction effect. Methods Both the AdEasy-KDR-CDglyTK cells with KDR-expressing SCG7901 cells and non KDR-expressing HepG2 cells were reconstructed, and then they were treated with the pro-drugs 5-FC and/or GCV at different concentrations. The killing effects of the transfection on the cells were evaluated. Flow cytometry was employed to determine the cell cycle distribution, and Hooechest/PI stain and electron microscopy performed to observe the pathological changes of cells. Results The green fluorescent protein (GFP) was observed in 95% of the infected SCG7901 and HepG2 cells when the multiple of infection (MOI) of the Ads was 100. No significant difference on the growth feature was found among the transfected SCG7901, HepG2 and untransfected SCG7901 and HepG2 cells. The infected cells exhibited different sensitivities to the two pro-drugs: SCG7901 cells infected with rAd were highly sensitive to the pro-drugs, while the infected HepG2 cells were not (P

Objective To study clinical features of liver damage in primary Sj(o)gren syndrome (pSS) and its related factors.Methods One hundred and forty-nine patients of confirmed pSS hospitalized at Peking University People's Hospital were analyzed retrospectively.Results Seventeen of 149 patients of pSS (11.4%) showed liver damage,10 diagnosed as autoimmune hepatitis and seven as primary biliary liver cirrhosis.Increased serum levels of IgG,IgM and γ-globulin accounted for 88.2% and 50.8%,35.3% and 5.3%,and 94.1% and 47.7% of those complicated with and without liver damage,respectively,with statistically significant difference (P ＜ 0.05).Positive serum anti-mitochondria antibody subtype M2 (AMA-M2) was 35.3% in pSS patients with liver damage,significantly higher than that in those without liver damage (1.5%) (P ＜ 0.05).Independent risk factors significantly associated with liver damage included age (OR = 1.013,95% CI 0.971-1.058),course of illness (OR = 1.089,95% CI 1.032-1.150),serum level of γ-globulin (OR = 4.021,95% CI 1.246-12.982),positive AMA-M2 (OR = 11.82,95% CI 0.005-0.157),and positive anti-SSA (OR = 101.333,95% CI 12.653-811.560).Conclusions Liver damage occurred rather high in pSS patients and increased serum levels of IgG,IgM,γ-globulin and anti-SSA can be used to predict their complication with liver damage.Age,course of illness,serum level of γ-globulin,positive AMA-M2 and positive anti-SSA are all significantly associated with liver damage in pSS patients.

Objective To measure hepatic blood flow of the normal liver and cirrhotic liver with hepatocellular carcinoma using multi-slice spiral CT(MSCT),and to evaluate the feasibility of the quantitative judgement of classification of liver cirrhosis with CT perfusion imaging.Methods CT dynamic perfusion imaging was performed in 53 subjects,including 32 patients of liver cirrhosis with hepatocellular carcinoma and 21 patients without liver disease(control subjects).The patients of liver cirrhosis with hepatocellular carcinoma were divided into three groups by CT morphologic classification :17 were classified as light liver cirrhosis group,8 as moderate group,7 as severe group.The parameters of CT perfusion included blood flow(BF),blood volume(BV),mean transit time(MTT),hepatic arterial fraction(HAF)and impulse residue function to(IRF To).The parameters were analyzed by the CT perfusion 3 software package(GE)with deconvolution method,and the correlation of the CT morphologic classification of liver cirrhosis with Child-Pugh functional classification was further evaluated.100 g-1,(17.81±6.59)ml/100 g,(9.52±3.08)s,0.20±0.08 and(4.38±2.35)s,respectively,while 0.27±0. 09 and (4. 14±2. 16)s, respectively. The mean BF, BV and HAF between normal livers and liver cirrhosis were statistically significant (P＜0. 05), and there were significant statistical differences in BF, BV and HAF among light, moderate and severe liver cirrhosis (P＜0. 05). The CT morphologic classification of liver cirrhosis was correlated positively with Child-Pugh classification (r=0. 935, P=0. 001 ). Conclusions Hepatic perfusion with MSCT can reflect the change of blood flow of cirrhotic liver, and MSCT perfusion can quantitatively evaluate the liver cirrhosis degree of patients with hepatocellular carcinoma.

Objective To compare the efficiency of laparoscopic cholecystectomy (LC) and radical cholecystectomy (RC) in the patients with early gallbladder carcinoma. Methods From January 2001 to December 2008, 63 patients who had underwent LC(28 cases) or RC(35 cases) were analyzed retrospectively. The survival and recurrence rate after operation and complication were compared. Results After treatment, the complication in the LC group was less than that in the RC group (7. 1% vs. 48. 6%, χ2 = 12. 675 ,P ＜0.01). In the RC group,the 1,3,5 year overall cumulative survival rate of Nevein phase Ⅰ were all 100%, and 76. 2%, 42. 9%, and 23. 8% respectively in the phase Ⅱ. The overall cumulative survival rate of LC cases were 81.8%, 54. 5%,27.3% in phase Ⅰ and 17.6% ,5.9% ,0.0% in phase Ⅱ, respectively. The survival curves between the two groups were significantly diffierent(phase Ⅰ χ2 =20.74,P＜0.001; phase Ⅱ χ2 = 11.35,P＜0.001) and the survival rate in the RC group was higher than that in the LC group. The 1,3,5 year cumulative recurrence rates in the RC were 20.0%, 48. 6%, 68. 6%, respectively, which is significantly lower than those in the LC group (60.7%,85.7% and92.9%, respectively)(χ2 =10.30,P=0.0013).Conclusions RC is one of the first choices for early gallbladder carcinoma treatment, and will decrease the recurrence rate and improve the long-term life quality.

Objective To investigate the influence of atorvastatin (Lipitor) on the expression of programmed cell death 4 (PDCD4) in human CD4+T lymphocytes in vitro. Methods Human CD4+T cells obtained from healthy individuals were activated with PHA and treated with atorvastatin. The mRNA and protein expression levels of PDCD4 were detected by real-time PCR and western-blot respectively. Results The stimulation of PHA obviously increased the mRNA and protein expression of PDCD4 and the secretion of those serum cytokines. The expression of PDCD4 and the production of serum TNF-α were significantly decreased, whereas the serum levels of IL-10 were significantly increased after treated by different concentration of atorvastatin. The serum secretion of TNF-α was positive correlation with the expression of PDCD4 through the linear related analysis (r=0.782, P<0.01), and the secretion of IL-10 was negative correlation with the expression of PDCD4 (r=-0.653, P<0.05). Conclusion The anti-inflammatory effects of atorvastatin are mediated by down regulating the expression of PDCD4 in CD4+T cells.

Objective: To observe the clinical efficacy of application in canicular days plus enteral nutrition in treating cough variant asthma (CVA) in kids, and to explore its action mechanism. Methods:Following a randomized controlled single-blind parallel-group design, 138 eligible kids with CVA were randomized into an observation group, a canicular-day application group, and an enteral nutrition group, 46 kids in each group. The canicular-day application group was intervened by application in canicular days, the enteral nutrition group was by enteral feeding, and the observation group was by both canicular-day application and enteral feeding. The therapeutic efficacies were evaluated after a treatment course. Results: The recovery rate and total effective rate were respectively 50.0% and 98.0% in the observation group, versus 23.9% and 91.3% in the canicular-day application group, and 13.0% and 78.6% in the enteral nutrition group. The observation group was significantly superior to the other two groups (bothP<0.05). In comparing the global symptom score, peak expiratory flow (PEF), forced expiratory volume in one second (FEV1), CD3+, CD4+, CD4+/CD8+, CD8+, hemoglobin (Hb), total protein (TP), albumin (ALB), eosinophil cationic protein (ECP), lipid peroxide (LPO), leukotriene (LT), body weight (BW), triceps skin-fold (TSF), and arm muscle circumference (AMC), the observation group was significantly better than the other two groups (bothP<0.05). Conclusion:Application in canicular days plus enteral nutrition can significantly improve the pulmonary function and symptoms in children’s CVA, and the effect is possibly produced by regulating cellular immune system, enhancing Hb, TP, ALB, BW, TSF, AMC, and inhibiting the production of ECP, LPO, and LT.
