This review analyzes and discusses these controversies in order to provide a meaningful reference for the diagnosis and treatment of atopic dermatitis.

Objective To investigate the regulatory effects of icariin (ICA) combined with the Panax notoginseng saponins (PNS) on immunological function in mice and provide some experimental evidences for the combination mechanism improving the spatial learning and memory abilities of Alzheimer's disease (AD) animal model. Methods Based on serum pharmacological method, the ICR mice were individually ig administrated with ICA+PNS [(40+320), (80+640), and (160+ 1 280 ) mg/kg] or ICA (80 mg/kg), and PNS (640 mg/kg) only for 7 d. Drug-containing serum was prepared and effects on spleen lymphocyte proliferation of Bable/c mice induced by concanavalin-A (ConA) or lipopolysaccharide (LPS) and on interleukin-2 (IL-2) secretion were observed in vitro. Meanwhile, the immunological organ indexes of treated mice were evaluated. Results Drug-containing serum of ICA+PNS [(80+640) and (160+ 1 280 ) mg/kg] could improve the spleen lymphocyte proliferation induced by ConA (P0.05). Drug-containing serum of ICA+PNS [(80+640) and (160+ 1 280) mg/kg] could improve IL-2 production (P0.05), respectively. Conclusion ICA combined with PNS could improve immunological function selectively and promote T cell function in mice.

Objective To study the morphological structure and the hemodynamics of peribiliary vascular plexus(PVP) of hepatic portal bile duct in rat in vivo,so as to provide an experimental method and accumulate data for further study on the bile duct complications occuring after liver transplantation,operations for bile duct stenosis and other hepatobiliary diseases.Methods Forty SD rats were randomly and equally divided into 2 groups: the control group and the ink-injection group(n=20),microcirculation laser scan confocal microscopy was used to observe the morphological structure and the hemodynamic features of PVP on rat′s hepatic portal bile duct after the bile duct was stained with indocyanine green and the hepatic artery was perfused with ink.Results Morphologically it was showed that PVP were comprised of three layers: the spatial structure of PVP appeared dentriform from outer layer to intermediate layer,and then transformed into a network from intermediate layer to inner layer.The outer layer vessels seemed to be dendritic and located within the ductal wall at 0-60?m scanning from the adventitia,and the branches appeared sparse and straight.The diameter of artery and vein was very different.The vessels of intermediate layer showed as an intricate network and located within the ductal wall in the depth of 40-80?m,and the ranification was rich and tortuous.Inner layer vessels adjacent to the intima appeared to be a plenus in hexagons with 120? intersect angles and uniform diameter.Hemodynamics showed that the flow rate in the artery was higher than that in the vein of PVP.Conclusion The technique,employing microcirculation laser scan confocalmicroscopy,to observe the morphological structure and the hemodynamic features of PVP,may reveal the morphological structure and hemodynamic features limpidly,both macroscopically and dynamically.It can be used as an important tool for the study of bile duct complications after liver transplantation,bile duct stenosis or other hepatobiliary diseases.

Objective To investigate the residual functions in the hepatic lobe with deprivation of bile duct by observation of histomorphological and functional changes in the hepatic cells in a rat model. Methods The right hepatic bile ducts of rats were obstructed with cyanoacrylate and then ligated two weeks after the left and caudate lobes were removed. The lobus quadratus hepatis served as self-control with or without portal vein ligation. The venous blood from individualized liver lobe was examined and histological observation was done to examine the histomorphological and functional changes in the hepatic cells. Results Compared to the controls of both sham operation and untreated lobe, the hepatic lobe with bile ducts deprived did not undergo atrophy significantly with few ultrastructural changes. The hepatocytes of the hepatic lobe with bile duct deprived contained plenty of mitochondria, ribosomes and rough endoplasmic reticulum when observed under transmission electron microscope (TEM). The results of periodic acid-Schiff staining revealed normal glycogen metabolism in the hepatic cells. No significant decrease was detected in the serum albumin and fibrinogen concentrations by examination of blood collected from vein of this liver lobe with deprivation of bile ducts. Conclusions The liver lobes with bile ducts deprived retain most of the liver functions such as protein synthesis and nutrition metabolism, and show no atrophy during the observation period. It is suggested that the hepatic lobes with bile duct deprived still possess the value of preservation. The present study has founded a theoretic basis for remaining the remaining liver lobes with bile duct deprived or ligated in some emergency and specific clinical situations.

Objective To investigate the correlation of clinical stage and treatment plan with prognosis in incidental prostatic carcinoma.Methods From 2004 to 2010,a total of 1076 patients diagnosed as BPH underwent transurethral plasma kinetic enucleation of prostate (TUPKEP) in our hospital,and their clinical data were respectively analyzed.Among them,42 cases were found to have incidental prostatic carcinoma.The correlation of clinical stage and treatment plan with prognosis in incidental prostatic carcinoma were observed.Results Among 1076 BPH patients undergoing TUPKEP operation,42 cases (3.9％) aged 56-88 years were found to have incidental prostatic carcinoma,which all displayed as prostatic adenocarcinoma including 18 cases at T1 a stage and 24 cases at T1b stage.10 cases received endocrinal therapy,14 cases received bilateral orchiectomy,14 cases underwent radical prostectomy and 4 cases were treated with watchful waiting.Patients were followed up for 24 to 96 months.The survival rates were 100.0％ and the rates of progression were 0.0％,20.0％,0.0％ in T1 a patients received watchful waiting,androgen-deprivation therapy and radical prostectomy,respectively.Total survival rate was 100.0％ and total rate of progression was 11.1％ in T1a patients.The survival rates were 71.4％,100.0％ and the rates of progression were 42.9％,0.0％ in T1 b patients received androgen-deprivation therapy and radical prostectomy,respectively.Total survival rate was 83.3 ％ and total rate of progression was 25.0 ％ in T1 b patients.Compared with T1 b patients,the total survival rate was higher (x2=18.19,P＜0.01) and the rate of progression was lower in T1 a patients (x2 =6.52,P＜0.05).Conclusions The survival rate in T1 a patients accepted androgen-deprivation therapy is similar to that in T1 a patients with watchful waiting.Compared with T1a patients,the survival rate is lower but the rate of progression is higher in T1 b patients received active androgen-deprivation therapy.The survival rate is higher in T1 b patients treated with radical prostectomy than in those received other treatments.Watchful waiting is acceptable for T1 a patients.T1 b patients should be treated with radical prostectomy for a better effect.
