OBJECTIVETo study the anxiety state of family members of newborns admitted to the neonatal intensive care unit (NICU) and investigate the influencing factors of their anxiety state.

METHODSThe self-designed questionnaire was used to collect the associated family information of 200 newborns who were admitted to the NICU. A self-rating anxiety scale was applied to investigate the anxiety state of the newborns' family members.

RESULTSThe anxiety score of the newborns' family members averaged 44.86+/-7.59, which was significantly higher than that of domestic norm of adult (37.23+/-0.58; P<0.05). The differences of the family members' anxiety score were related to the severity of baby's diseases, their educational level and family's economic condition as well as the locality of the family (countryside or city). The more severe the baby's illness, the higher anxiety score of the family members had. The family members with higher educational levels or poorer economic conditions had higher anxiety scores. The anxiety score of the family members from the countryside was higher than that of the family members from city.

CONCLUSIONSThe family members of NICU newborns have obvious anxiety. The degree of anxiety is associated with the severity of baby's illness, educational level of the family member, family's economic condition and the family locality (countryside or city). These results remind the medical staff working in the NICU should pay more attention to communicating with the family members in a compassionate way and help them to cope with this stressful situation.

Objective The aim of this study was to investigate the characteristic of regional cerebral glucose metabolism in patients with Wilson's disease (WD) using 18F-fluorodeoxyglucose (FDG) PET.Methods Thirteen WD patients and 12 normal controls were studied by brain 18F-FDG PET, and the data were analyzed by visual analysis, semi-quantification and statistical parametric mapping (SPM). The radioactivity ratios of lenticular nuclei, caudate, thalamus and cerebellum to cerebral cortex and the ratio of lenticular nuclei to caudate were calculated, respectively. SPSS 11.0 software for statistics was also used to analyze the data. Results In WD patients, radioactivity of lenticular nuclei and candate was significantly decreased compared with controls. The radioactivity ratios of lenticular nuclei and caudate to cerebral cortex in WD patients were both significantly lower than that in normal controls (0.95±0.05 vs 1.26±0.05, t =15, P < 0.05 ; 1.02±0.06 vs 1.17±0.05, t = 8, P < 0.05), and the ratio of lenticular nuclei to caudate in WD patients was significantly higher than that in normal controls (0.93±0.06 vs 1.09±0.06, t =9, P< 0.05). Conclusion As compared with normal controls, patients with WD had significantly decreased glucose utilization in the basal ganglia, especially in the lenticullar nuclei.

Objective:To analyze the activities of human NKG2D ligand MICA/B promoter induced by 5-Fu.Methods:The 5'-end flanking regions of MICA /B promoter and their different truncated fragments were amplified from A549 genome by PCR. The resulting amplicons were cloned into pGL3-Basic vector to generate the MICA/B luciferase reporter plasmids. All the constructs were transiently transfected A549 cells. The promoter region activities were determined by dual-luciferase reporter assays. The effect of 5-Fu on the promoter activities of MICA/B was also tested.Results and Conclusion:The 5'-end flanking regions of MICA /B promoter and five of their different truncated fragments were successfully obtained. The normalized luciferase reporter gene activities driven by the above promoters and fragments were 3.61,2.26,1.63,0.313,0.711 and 0.663 for MICA and 17.49,10.11,7.398,0.822,0.997 and 0.49 for MICB,respectively. Promoter activities in transiently transfected A549 cells treated by 20,40,80,160 and 320 μg/m of 5-Fu increased 1.69,1.48,1.62,1.55 and 1.78 fold for MICA and 1.44,1.87,1.38,1.19 and 1.25 fold for MICB. Our results suggest that 5-FU can significantly up-regulate the promoter activity of both MICA and MICB.

OBJECTIVETo explore the effect of moxibustion at Sanyinjiao (SP 6) on normal process of childbirth and safety of mothers and infants.

METHODSOne hundred and seventy-four cases of singleton primiparas, fetal head position were selected as the subjects and divided into three groups by single-blind randomized method: an acupoint group (n = 59), a non-acupoint group (n = 57) and a blank group (n = 58). When the cervix was dilated by 2 to 3 cm, DAJ-23 type multi-function moxibustion apparatus was used at Sanyinjiao (SP 6) in acupoint group, and at non-acupoint spot (the midpoint from the radial arterial pulse throbbing place on the radial side of the transverse crease of the wrist to the radial end of biceps tendon of the elbow) in non-acupoint group, 30 min for each one. The conventional labor care was adopted in blank group. The differences were observed in the first active stage, the second stage and the third stage of the labor as well as the safety of mothers and infants among three groups.

RESULTSThe durations of the first active stage of labor [(123.05 +/- 96.401) min] and the second stage [(37.407 +/- 22.390) min] in acupoint group were shorter than those [(171.40 +/- 94.339) min, (49.517 +/- 25.373) min] in non-acupoint group, as well as those [(178.79 +/- 97.231) min, (53.684 +/- 20.087) min] in blank group separately (all P < 0.05). It was discovered that the progressions of the first active stage and the second stage of labor were accelerated in acupoint group, and there was no statistically significant difference in the third stage of labor among the three groups (all P > 0.05). Bleeding amount after childbirth in acupoint group was less than those in non-acupoint group and blank group (both P < 0.05), and Apgar scores of newborns in acupoint group and non-acupoint group were higher than that in blank group (both P < 0.05).

CONCLUSIONMoxibustion at Sanyinjiao (SP 6) can shorten the process of childbirth, reduce postpartum bleeding and has no harmful impact on mothers and infants.

Objective Effectiveness of two kinds of thermochemotherapy infusion from intraarterial approach were studied in the grafted liver VX2 tumors of rabbit.Methods VX2 tumor model was established in 30 Newzland rabbit's livers.Percutaneous transfemoral hepatic arterial catheterization with fixation of the cathether tip inside the feeding vessel was carried out under DSA guidance.All 30 rabbits were divided into three groups(n=10 in each group),normal temperature 100 ml saline+Adriamycin(ADM)infusion(group 1),60℃100 ml saline+ADM continuous perfusion(group 2)and 60℃100 ml saline+ADM intermittent perfusion(group 3).After the perfusion,the lasting time periods of 43-45℃for tumor tissue of group 2 and 3 together with the concentrations of ADM within tumor's tissue were measured.Results Concentrations of ADM were shown as(12.013?2.237)?g/ml,(17.622?1.368)?g/ml,and(11.519?1.225)?g/ml for group 2, group 3 and group 1 respectively.60℃intermittent perfusion vs 60℃continuous perfusion showed P＜0.05, 60℃continuous pefusion vs normal temperature perfusion also showed P＞0.05. 43-45℃period lasting time (min)for 60℃continuous pefusion vs 60℃intermittent pefusion were(4.1?2.7)min and(11.3?3.3)min respectively,the latter was three times more than the former.There were no differences shown betwen the temperature,respiration and heart rate of group 2 and group 3.Conclusion Intermittent intraarterial perfusion thermochemotherapy is a more effective interventional management among all thermochemotherapies.
