OBJECTIVETo observe the effects of electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) com- bined with granisetron on nausea and vomiting as well as serum levels of 5-hydroxy tryptamine (5-HT) and dopamine (DA) in chemotherapy patients.

METHODSSeventy-two chemotherapy patients who met the inclusive criteria were randomly divided into an observation group (38 cases) and a control group (34 cases). The patients in the observation group were treated with electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron injection; the patients in the control group were treated with electroacupuncture at sham-point 1 and sham- point 2, and the rest treatment was identical to the observation group. After 3-day treatment, the clinical indices including times of vomiting and severity of nausea, etc. were observed in the two groups.

RESULTS(1) At the acute stage within 24 h, the times of vomiting in the two groups were not significantly different (P>0.05); at the delay stage, the severity of nausea was significantly higher in the control group (P<0.05). (2) As for the comprehensive efficacy and rate of complete control, there was no obvious difference between the two groups at the acute stage (P>0.05); while in the delay stage, the rate of complete control in the observation group was superior to that in the control group (P<0.01). (3) Compared before and after the treatment, serum levels of 5-HT and DA were evidently reduced in the observation group (both P<0.05), while those in the control group were not significantly changed after treatment (both P>0.05).

CONCLUSIONElectroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron could obviously relieve the nausea in chemotherapy patients at the delay stage. The effect mechanism is possibly related to reducing the content of 5-HIT nndl nA

Objective To explore the association between type 2 diabetes mellitus (T2DM)combined with non -alcoholic fatty liver disease (NAFLD)and serum adiponectin (APN)and its clinical significance.Methods A total of 76 patients who were initially diagnosed with T2DM or had been diagnosed with T2DM for less than three years and admitted to the endocrine department and its outpatient clinic of the Affiliated Hospital of Medical School of Ningbo University from August 2011 to July 2013 were selected as the subjects,and were assigned to group A or B,each consisting of 38 patients,based on the presence or absence of associated NAFLD.Another 30 healthy subjects receiving physical examination were assigned to the control group (NC group).The indicators including body mass index (BMI),blood lipids,blood glucose,liver function,insulin resistance index (HOMA -IR)and serum APN,were measured and compared among the groups. Results In group A ,the indicators including BMI,triglyceride (TG),total cholesterol (TC),low density lipoprotein -cholesterol (LDL -C),alanine aminotransferase (ALT),fasting insulin (FINS)and HOMA -IR were significantly higher than those in group B and NC group,and the APN level was significantly lower than that in group B and NC group (P <0.05).Pearson correlation analysis indicated that APN was negatively correlated with BMI,TG,high density lipoprotein -cholesterol(HDL -C),and HOMA -IR,and positively correlated with TC,LDL -C and ALT(P <0.05).Multiple linear regression analysis suggested that HDL -C and HOMA -IR was the independent influencing factors for APN (P <0.05).Conclusion Severe insulin resistance and glucose and lipid metabolic disorders are present in T2DM patients combined with NAFLD,and adiponectin level is of vital significance for the development and progression of NAFLD.

Objective:To observe the clinical effect of acupoint sticking of Chinese medicine at Shenque (CV 8) for preventing spleenstomach disharmony caused by venous analgesia pump.Methods:A total of 120 post-surgery patients using venous analgesia pump and also conforming to the inclusion criteria were randomized into 2 groups by the random number table.There were 58 patients in the control group who received conventional post-surgery nursing care,and there were 62 patients in the treatment group who received acupoint sticking at Shenque (CV 8) on the basis of conventional nursing care.After treatment,the incidences of postoperative nausea and vomiting,and abdominal bloating were measured.Results:The total incidence of nausea,vomiting and abdominal bloating in the treatment group was 11.3％,versus 39.7％ in the control group,and the difference of the incidence between the two groups showed a statistical significance (P＜0.05).In comparison of the severity of spleen-stomach dishormony which happened during 72 h after surgery,cases in the treatment group showed lower severity than those in the control group (P＜0.05).Conclusion:Acupoint sticking at Shenque (CV 8) can effectively prevent spleen-stomach disharmony caused by venous analgesia pump,which will alleviate sufferings of the patients.

AIM:To investigate peripapillary vessel density and its relationship with other ocular parameters in highly myopic eyes with peripapillary intrachoroidal cavitation (PICC), and to analyze risk factors for PICC.METHODS:Cross-sectional study.A total of 35 highly myopic eyes with PICC, 40 highly myopic eyes without PICC and 35 normal eyes were included in this study.All participants underwent fundus photography and spectral-domain optical coherence tomography (SD-OCT).OCT angiography was also performed to image the retinal vasculature in the peripapillary areas of different sectors, including the radial peripapillary capillaries (RPC) and optic nerve head (ONH) layer.The difference of morphology changes in optic disc and peripapillary vessel density between these three groups were compared.Correlations between peripapillary vessel density and PICC and risk factors for the presence of PICC were analyzed.RESULTS: Significant differences were found among the three groups in spherical equivalent refraction (SER), best-corrected visual acuity (BCVA), axial length, peripapillary atrophy β-zone (β-PPA) area, retinal nerve fiber layer (RNFL) thickness and the presence of tilted optic disc, posterior staphyloma and myopic maculopathy (MMD) (P<0.05).There were significant differences among the three groups in the peripapillary vessel density both in RPC (54.34±5.58, 57.54±7.44, 64.42±3.50) and ONH (51.24±7.43, 52.75±9.96, 61.25±4.15) layers (P<0.001).In highly myopic eyes, vessel density was significantly lower in eyes with PICC than in those without in inferotemporal area both in the RPC (56.76±6.62,63.84±6.02,67.52±4.78) and ONH (56.47±5.79,60.38±4.72,64.18±4.37) layers.The vessel density was significantly correlated with the presence of MMD, β-PPA area and RNFL thickness in the RPC layer, whereas correlated with the presence of MMD, PICC and RNFL thickness in the ONH layer (P<0.05).Tilted optic disc and posterior staphyloma were independent risk factors for the presence of PICC (OR=8.007, 95%CI: 2.045-31.348;OR=7.558, 95%CI: 1.398-50.026).CONCLUSION:Highly myopic eyes with PICC had relatively lower peripapillary vessel densities, especially in the temporal area, than those without.Tilted optic disc and posterior staphyloma were independent risk factors for the presence of PICC.

Objective To explore clinical significence of soluble vascular cell adhesion molecular(SVCAM - 1),immunoglobulin A (IgA) anti- endothelial cells antibodies(AECA) in Henoch-Schonlein purpura(HSP) and their relationships. Methods SVCAM-1 were detected by ELISA between 55 cases with HSP (40 cases in acute stage and 15 cases in recovery) and 20 controls. Results The levels of serum SVCAM - 1 of the HSPN cases were significantly increased compared with the other HSP. In addition, the serum level of SVCAM - 1 in acute stage HSP children was significantly higher than that in recovery stage and normal controls. IgA AECA positive rate in HSPN was higher than that of without nephritis group. The level of serum SVCAM - 1 in IgA AECA positive children was higher than that of IgA AECA negative children. Conclusion SVCAM - 1 and IgA AECA may participate in the pathogegesis of HSP, and the level of molecule is correlated with the progress of HSP.

Objective To observe the behavior changes and synaptic reconstruction of brain and the impact of gastrodin in rats with epilepysy induced by pentylenetetrazole.Methods Fifty Wistar rats in growth(50-70 g) were randomly divided into 5 groups:control group,Pentylenetetrazole (PTZ) group,gastrodin high dose group,gastrodin low dose group and sodium valproate group,each group had 10 rats.According to Racine classification,the behavior changes of rats and the frequency were recorded.Conventional method was adopt to perfuse cordis, fix and extract the brain,and the immunohistochemistry was used to detect synaptophysin(P38) expression in the temporal lobe and hippocampus of the brain after 4 weeks.Results 1.Four weeks after pentylenetetrazole ignited the growth period rats,the attack-level of each experimental group through comparison with each other,there was statistically significant difference(?2=35.83 P0.05).Conclusions There are mossy fiber sprouting and the formation of synaptic reconstruction in temporal lobe and hippocampus of the growth period rats repea-tedly ignited by pentylenetetrazole.Gastrodin may play a role in the formation of antiepileptic obviously,and through decreasing the expression of P38,which can inhibit the formation of synaptic reconstruction,as control seizures indirectly.
