Objective:To investigate the inhibition control characteristics in college students with mobile phone addiction,then to design tactics to enhance their inhibition control ability.Methods:Totally 150 college students were surveyed with the Mobile Phone Addiction Index (MPAI)to filter out the high and low mobile phone addiction.Thirty students with more than eight affirmative answers to the seventeen MPAI items were selected as the mobile phone addiction group while another 30 students with less than eight affirmative answers were selected as non addicts group of MPAI.All participants were asked to complete task of stop signal.Results:In college students with mobile phone addiction,the stop-signal reaction times were longer than that in the students without mobile phone addiction [(292.0 ±89.4)ms vs.(241.1 ±95.7)ms,P <0.05],while the non-signal reaction times were shorter than that in those without mobile phone addiction [(494.2 ±103.8)ms vs.(597.6 ±108.9 )ms,P<0.01].Conclusion:It suggests that the college students with mobile phone addiction may have poorer inhibitory control.

ObjectiveTo study the clinical feature, diagnosis, treatment and prognosis of hepatic angiomyolipoma.Methods The clinical materials of eight surgically treated patients with hepatic AML were retrospectively analyzed.ResultsThere were five females and three males, with age ranging from 25 to 59 years (mean 39 6 years). Tumors were located in the right lobe of the liver in 5 cases, and in the left lobe in 3 cases. Ultrasonography and computed tomography were performed in all cases. Magnetic resonance imaging and angiography were done in two each cases. The myoid cells in all tumors showed over expression of HMB 45. One patient died of postoperative heart failure, seven were followed up for 9 mos to 12 years without tumor recurrence. Conclusions Comprehensive imaging features can reveal the characteristic components of hepatic angiomyolipoma. HMB 45 immunostaining can be used to confirm the diagnosis. Surgical resection is an effective treatment of hepatic AML.

Objective To explore the brain changes of electroacupuncturing (EA) different acupoints of peripheral facial paralysis (PFP) with functional magnetic resonance imaging (fMRI). Methods Eighteen patients with left PFP were randomly divided into three groups. Six of them received electroacupuncturing left Dicang, 6 received electroacupuncturing left Hegu, and 6 received electroacupuncturing left Houxi. fMRI data were obtained from scanning of the whole brain. Functional data were processed by SPM99 software and functional responses were established with t-test analysis (P<0.05). Results Electroacupuncturing Dicang and Hegu on the left induced decreasing of signal in bilateral middle frontal gyrus, left cingulate gyrus, signal increased of right precentral gyrus, bilateral postcentral gyrus, left superior temporal gyrus and right insular, while electroacupuncturing Houxi on the left induced decrease of signal in bilateral inferior frontal gyrus, left lentiform nucleus, right middle temporal gyrus, right cerebellar tonsil, signal increased of right caudate head, right cingulate gyrus, brainstem, cerebellar vermis and right parahippocampal gyrus. Conclusion Electroacupunctuing Hegu and Dicang can cause corresponding functional activation in cerebrum, while electroacupuncturing Houxi can not, suggesting that there is association between cerebral and acupoint of owned meridian.

ObjectiveTo investigate the correlation between electro-acupunctured point Houxi(SI3)and activated brain function areas, contrast the images produced with electroacupuncture at left and right points Houxi and make a comparison with electroacupuncture at point Hegu(LI4)in patients with peripheral facial paralysis.MethodPatients with peripheral facial paralysis, six on the left side and six on the right side, were enrolled as subjects. A scan of the whole brain was taken using fMRI during electroacupuncture stimulation. The images were processed using SPM software. An analysis using at-test (P<0.01) showed differences in brain functional images produced with electroacupuncture at different points.ResultElectroacupuncture at left point Houxi increased the signals of brain regions: rightcaudate nucleus, right cingulate gyrus, right parahippocampal gyrus, right superior temporal gyrus, the brainstem and the cerebellar vermis. Electroacupuncture at right point Houxi increased the signals of brain regions: right medial frontal gyrus, left middle frontal gyrus, left anterior cingulate gyrus, rightcingulate gyrus and right superior temporal gyrus.ConclusionThere is a difference in the image between electroacupuncture at point Houxi and at point Hegu or Dicang(ST4). There is also a larger difference in the image between bilateral points Houxi. The brain regions with high-frequency or low-frequency signals are not consistent. The results further prove the scientificalness of “Point Hegu is indicated for diseasesin the face and mouth” and also show that the cognominal acupoints on the two sides ofthe human body may have some differences, e.g. the conduction pathways are not completely the same and the therapeutic effects are not completely consistent.

OBJECTIVE: To observe the effects of Jianpi Huoxue Decoction, a compound Chinese herbal medicine, on Kupffer cell signal pathway activation in rats with liver injury induced by Lieber-Decarli liquid diet and lipopolysaccharide (LPS). METHODS: SD rats were divided into normal, control liquid diet, ethanol liquid diet and ethanol liquid diet plus Jianpi Huoxue Decoction group. Rats were administrated with Jianpi Huoxue Decoction or distilled water via gastrogavage for 4 weeks after administration with ethanol or control liquid diet for 2 weeks respectively. After that, rats in each group were stimulated with LPS via gastrogavage for 3.5 h and harvested. Alanine aminotransferase (ALT) in serum and triglyceride (TG) in liver were analyzed. Pathological changes in liver tissues were observed in HE staining section. Tumor necrosis factor-alpha(TNF-alpha) in portal vein plasma was assayed by ELISA. The protein expressions of CD68, Toll-like receptor 4 (TLR4), phosphorylation-I kappa B (P-I kappa B) and TNF-alpha in liver were evaluated with Western-blotting. RESULTS: After the treatment with Jianpi Huoxue Decoction, the pathologic changes in liver tissue were lightened, levels of ALT in serum, TG in liver and TNF-alpha in portal vein plasma were decreased, and the protein expressions of CD68, TLR4, P-IkappaB and TNF-alpha in liver were reduced. CONCLUSION: Jianpi Huoxue Decoction can inhibit Kupffer cell signal pathway activation in rats with liver injury induced by Lieber-Decarli liquid diet and LPS.

AIM: To study the role of injury and phenotype shift of liver sinusoidal endothelial cells in the development of portal hypertension of liver cirrhosis in rats. METHODS: The rat liver cirrhosis model was established by peritoneal injection of dimethylnitrosamine (DMN) (at a dose of 10 mg?kg~(-1), 3 times a week, for 4 weeks). The dynamic changes of liver cirrhosis were observed at different time points (1 day, 2 days, 3 days, 1 week, 2 weeks, 4 weeks, 6 weeks and 8 weeks). The pressure of portal vein (Ppv), the expression of CD44, von Willebrand factor (vWF), endothelin-1 (ET-1) mRNA and endothelial nitric oxide synthase (eNOS) mRNA, the serum hyaluronic acid (HA) content and liver ET-1 content were measured. RESULTS: Compared with the normal control rats, CD44 positive staining was weak in the 1 day model rats, and the numbers of fenestrae of sinusoidal endothelial cells (SECs) rapidly decreased, but serum HA content rapidly increased (P

BACKGROUND:Hepatic fibrosis in chronic liver disease can be reversed. Studies have shown that Periplaneta americana extract has anti-fibrosis effect, and has protective effect on the experimental hepatic fibrosis rats.
OBJECTIVE:To observe the effect of Periplaneta americana extract sticky sugar amino acid on hepatic fibrosis, and to primarily explore the mechanism of sticky sugar amino acid against hepatic fibrosis.
METHODS:Rat models of immune hepatic fibrosis were induced by pig serum and intragastricaly administered 0.5, 0.25, 0.10 g/kg sticky sugar amino acid. Four indexes of hepatic fibrosis were detected by radioimmunoassay. Immunohistochemical staining wasused to measure transforming growth factor beta 1, tissue inhibitor of metaloproteinase protein expression intensity and positive cel rate, to determine the correlation of different concentrations of sticky sugar amino acid, transformation growth factorbeta 1 and tissue inhibitor of metaloproteinase.
RESULTS AND CONCLUSION:(1) The Periplaneta americana extract sticky sugar amino acid reduced the levels of laminin, type III procolagen, type IV colagen and hyaluronidase (P< 0.01) and reduced the expression of transformation growth factor beta 1 and tissue inhibitor of metaloproteinase 1 in liver tissue (P< 0.01). (2) Sticky sugar amino acid concentration and transformation growth factor beta 1 and tissue inhibitor of metaloproteinase 1 protein expression showed a significant negative correlation (|r| > 0.9). (3) Results confirmed that the Periplaneta americana extract sticky sugar amino acid can change the reversal of hepatic fibrosis. Its mechanism of action is associated with expression of transforming growth factor beta 1 and tissue inhibitor of metaloproteinase 1 inhibited by sticky sugar amino acids.

Objective To observe the effects of acupuncture therapy on triglyceride (TG) content of quadriceps femoris in the high fat diet feeding-induced insulin resistance rats; To discuss acupuncture mechanisms to improve the insulin sensitivity. Methods Thirty-two Wistar rats at the age of eight weeks were randomly divided into normal group, model group, electro-acupuncture group, and sham electro-acupuncture group. The normal group was given basic diet, and model group, electro-acupuncture group and sham electro-acupuncture group were given high fat diet for 8 weeks, after which, the model of insulin resistance was successfully obtained. Electro-acupuncture group was given acupuncture therapy with “Guanyuan (GV4)”, “Zhognwan (GV12)”, “Zusanli (ST36)”, and “Fenglong (ST40)” for 8 weeks. Sham electro-acupuncture group was given stimulation at non-acupuncture points which were not on the meridians and near the acupoints but not at the area of the acupoints. In addition, food intake and body weight of each group were recorded, blood glucose was tested, TG content of quadriceps femoris was measured by enzymatic method after the treatment. Results The weight of the rats and TG levels of quadriceps femoris in electro-acupuncture group and sham electro-acupuncture group were significantly lower than those in model group, with significant statistical difference (P<0.05), especially in electro-acupuncture group. Conclusion Acupuncture therapy could improve insulin sensitivity to prevent and its related diseases.
