Objective To observe the clinical efficacy of Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine in treatment of chronic urticaria (CU). Methods Totally 108 CU patients were randomly divided into treatment group and control group, 54 cases in each group. The treatment group was given Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine (10 mg, 1 time per day) according to symptom controlling situation, and control group with the decreasing amount of loratadine only. Both groups were treated for 4 treatment courses (2 weeks as a treatment course). Symptom score reduce index was used to calculate the effective rate after 8 weeks of treatment. And the taking antihistamine medicine score was recorded 4, 6, 8 weeks of treatment. The follow-up visits were made to observe long-term efficacy of the cured patients 1 month, 3 months and 6 months after discontinuing the medication. Results Totally 27 cases from the treatment group were cured, with a total short-term effective rate of 96.30%;13 cases from the control group were cured, with a total short-term effective rate of 65.38%, with statistical significance (P<0.05). The taking antihistamine medicine score in treatment group (0.553 ± 0.239) was lower than that in control group (0.721 ± 0.245), namely the symptom improvement in treatment group was better than that in control group by taking less antihistamine medicine. Long-term clinical efficacy showed that the treatment group was also distinctively better than the control group. Conclusion Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine is more effective for CU, and with better short-term and long-term clinical efficacy than the control group.

Objective To understand the dietary intake of pregnant women, and try to give a reasonable sug-gestion to promote fetal development. Methods 400 pregnant women in Fushan city were enrolled in this study and their dietary intake were investigated, then the software of Analysis of pregnancy nutrition guidance system was used to make nutrition analysis. Results The ratio of the energy in each pregnancy provided by dietary protein, carbohy-drate and fat were relatively appropriate. But the intake of dietary calcium, ferrum, zinc, vitamin B1 and vitamin B2 in early pregnancy were very low, the intake were respectively 764.51 mg, 26.94 mg, 15.71 mg, 1.12 g, 1.13 g. Each pregnancy the ratio of high-quallty protein in total protein intake were more than 50%, an average protein RNI% was 48.50%. Conclusion The dietary style of pregnant women is relatively reasonable. But they should strengthened nutritional guide to intake more calciuro,ferrum, zinc,vitamin B1 and vitamin B2.

Objective To investigate the alternation of left ventricular systolic function in patients underwent transcatheter aortic valve implantation operation(TAVI) by three-dimensional speckle tracking technology (3D-STI).Methods Totally 20 patients with severe aortic stenosis were enrolled.All the subjects underwent successful TAVI operation.The real-time 3D full volume datasets on apical four-chamber view were acquired on before,7 days and 1 month after TAVI.Left ventricular global longitudinal strain(GLS),regional peak systolic longitudinal strain(LS),regional peak systolic circumferential strain(CS) and regional peak systolic radial strain(RS),were analysed using off-line TomTec software,the differences among the three groups were compared.Results Compared with the preoperation,aortic valve blood flow velocity (AV),mean aortic valve pressure gradient(mPAG) of 7 days after operation decreased significantly.Threedimensional left ventricular ejecation fraction(3D-LVEF) among the patients whose 3D-LVEF under 50％had a remarkable increase and whose 3D-LVEF exceed 50％ before operation had no significant change,while 1 month after operation the 3D-LVEF had a significant improvement compared with the preoperational data regardless of 3D-LVEF under 50％ or not.The GLS and LS of all segments of 7 days after TAVI were higher than pre-operation(all P ＜0.05),and it had a further improvement 1 month after TAVI.Conclusions LV systolic function had improvement early after TAVI.3D-STI is a new,convenient way to detect the global and regional left ventricular systolic function of TAVI patients.

Objective To investigate if anodal transcranial direct current stimulation (atDCS) of the right cerebellum improves verbal working memory in amnesic persons with mild cognitive impairment (aMCI).Methods Thirty-nine aMCI were randomly divided into an observation and a control group using a random number table.The observation group was given atDCS at 1.2 mA for 20 minutes every day for 5 days,while the control group was provid ed with fake atDCS in the same way.Before and after the treatment,both groups were tested using forward and back ward digit spans,word reading,visually cued sensorimotor tests and finger tapping.Results After the treatment,the forward and backward digit spans of the observation group had improved significantly compared with before the treatment and with the control group's improvements.Significant improvement was observed in the average backward digit span of the control group,but not in their forward digit span after the treatment.No significant differences be tween the two groups were observed in the other measurements before or after the treatment.Conclusion Direct current stimulation of the cerebellum may improve the verbal working memory deficits of aMCI.Further research should be conducted to find the mechanism.

Objective:To establish a three-dimensional visualization model of craniofacial hard and soft tissues with data based on CT. It could be used in clinic as diagnosis and operation simulation. Methods:Original data of patients' craniofacial hard and soft tissues by CT scanning was transferred into the system. After 2-D and 3-D image preprocessing, advanced Marching Cubes Algorithm (Marching Tetrahedron Algorithm) was used for surface fitting;3-D volume rendering was accomplished by footprint method. Results: The whole craniofacial frame and its surface could be observed clearly in reconstructed 3-D Model. Furthermore, the 3-D Model could be seen from any sight angle and sectioned in any direction and place. Doctors could observe the characters of craniofacial deformity for more details. Conclusion: The problems of X-ray reflection of metal brackets, control of X-ray dosage and time spending in 3-dimensional visualization model reconstruction were solved. This model could be used in clinic for diagnosis and operation simulation.

AIM To study the effect of desipramine (DMI ) on proliferation inhibition and apoptosis induction of rat glioma C6 cells. METH ODS Cell proliferation was measured by MTT col- orimetric assay and cells undergoing apoptosis were determined by electron microscope and flow cytometry. The expression of hcf-2 was evaluated by immunohistochemistry. RESULTS DMI could result in the concentration- dependent inhibition of C6 cell proliferation and lead to arrest in GO - G1 phase of cell cycle. The value of Ica and 95% confidence limits were 20.7(17 .3~24 .2) ?mol?L~ 1. DMI(40 ?mol? L-l )-induced apoptosis showed classical apoptotic morphology and the hypodiploid peak appeared on the histogram of FCM in a concentration- dependent man ner, which could be abrogated by cycloheximide(1. 8 ?mol? L- １ ). Meanwhile, DMI (10 ?mol? L- 1 ) could down-regulate the expression of apoptosis associated gene hcl-2. CONCLUSION DMI could inhibit cell proliferation in a concentration dependent manner and induce typical apoptosis of C6 cells.
