Bullous pemphigoid (BP) antigens are of molecular heterogeneity. To find out the relationship between the antigenic molecular heterogeneity and clinical features, treatment and prognosis in BP, 122 sera of BP patients were tested with immunoblotting technique. The results showed that 94 sera reacted with BP antigens extracted from normal human epidermis. Among them, 54 sera (57.4%) had BP 230kD antibody and 83 sera (88.3%) had 180kD antibody. Based on the results of immunoblotting assay, these 94 BP patients who had the positive antibodies were divided into three groups, including group I patients with 230kD protein antibody only, group Ⅱ patients with 180kD protein antibody and other minor protein antibodies, and group Ⅲ patients with both 230kD and 180kD antibodies. The pattern of clinical presentations (mucosal involvement, scarring and milia), disease severity, the largest dose of prednisone per day and duration of hospitalization were compared in these three groups. The results of comparison showed that there was no statistically significant difference among three groups in above mentioned items, except the difference of the largest dose of prednisone between the group Ⅰ and group Ⅱ (t=2.22, P

In recent years,along with the deepening study of bone marrow mesenchymal stem cells (BMSCs),the repair effect of BMSCs in various tissue injury have been gradually revealed.And in recent years,except the ability of differentiate to the target cells,its paracrine effect,for example,a variety of cyto-kines secreted by BMSCs,also plays an important role in the process of repairing.

Objective To investigate the effect of hyperoxia on the expressions of cysteinyl aspartate specific proteinase -3(Caspase -3)and proliferating cell nuclear antigen (PCNA)in bone marrow mesenchymal stem cells (BMSCs).Methods Primary BMSCs from SD rats were cultured in vitro,BMSCs grew to 70% -80% degrees of fu-sion and then were randomly divided into room air group and hyperoxia exposure group.Each group was divided into 5 sub -groups,and cultured for 0,3,6,1 2,and 24 h respectively.Morphology investigation with inverted phase contrast microscope was adopted.The expressions of Caspase -3 and PCNA protein levels were detected by Western blot. Results (1 )As time wenty by,compared with room air group,the gap between cells increased,some of the cells be-came circular,and cell detachment and floating appeared in the hyperoxia -exposure group (>1 2 h)compared with room air group.(2)As time went on,compared with the room air group,the expression levels of Caspase -3 protein in the hyperoxia -exposure group were increased,and the difference was significant after 6 hours of culture (0.27 ± 0.04 vs 0.1 4 ±0.02,t =5.03,P =0.007).(3)Compared with room air group,the PCNA levels of the hyperoxiaexpo-sure group(6 h)decreased,and the difference in PCNA protein expression levels was significant after 6 hours of culture (0.27 ±0.04 vs 0.38 ±0.04,t =3.37,P =0.028).Conclusions Hyperoxia exposure increases Caspase -3 expres-sion levels and decreases PCNA expression,which may affect the proliferation and apoptosis of BMSCs.

Primovist is a newly developed hepatocytespecific agent that is transported into the hepatocyte through organic anion transporting polypeptides (OATPs) and excre ted into bile through canalicular multiorganic anion trans porters.Primovist uptake is usually reduced in HCC cells that present hypointensity on the hepatobiliary phase,there fore this agent may help differentiate HCC from other neoplasms and improve histological grading.This article will further explore the use of Primovist in liver cirrhosis and small hepatocellular carcinoma.

Objective To study the effect of motor imagery therapy combined with conventional physical training on hemiplegia lower extremity function in stroke patients with hemiplegia.Methods Thirty hemiplegic patients meeting the eligible criterions were randomly divided into two groups: a treatment group (n = 13 ) and a control group ( n = 17).All subjects accepted conventional rehabilitative treatment.Patients in treatment group were treated with motor imagery therapy after physical training, while the patients in control group were treated with physical training only.Motor function was measured by the percentages of changes in maximum loading on affected lower limb (PL%), Barthel index (BI), 5m maximum back and forth walking speed (5m MBFWS), Berg balance scale ( BBS), Fugl-Meyer motor assessment ( lower limb) (FMA-L) before the beginning of training and at the end of sixweek training.Results In both groups, all measurements at the end of training improved significantly ( P < 0.01 )compared to that at the beginning of training.After the whole training course, PL% and 5m MBFWS (m/s) in treatment group were significantly better compared to those in control group( P < 0.05 ), and the other measurements were not statistically significant between two groups( P > 0.05 ).Conclusion Motor imagery therapy had positive effect on hemiplegia lower extremity function of sub-acute stroke patients.

Objective To explore the effect of collaborative health education by both doctors and nurses on parturition?Methods One hundred and sixty primiparas at uterogestation undergoing analgesic parturition were assigned equally into the control and observation groups according to their admission sequence? The control group received routine nursing intervention and the observation group the collaborative health education by both doctors and nurses? The two groups were compared in terms of analgesic effect,vaginal delivery and post-partum hemorrhage? Result The rates of analgesic delivery and vaginal delivery in the observation group were significantly higher and the volume of postpartum hemorrhage was significantly smaller than those of the control group(all P < 0?05)?Conclusion The collaborative health education may be effective in alleviating mental stress of the preimiparas,enhancing the analgesic effect,increasing the rate of vaginal delivery and decreasing the volume of postpartum hemorrhage?
