Objective To explore the effect of Bailing capsule on epithelial-mesenchymal transition( EMT) in rats with adenine-in-duced tubulointerstitial fibrosis. Methods Tubulointerstitial fibrosis animal models were established and SD rats were divided into mo-del group ( n = 30), treatment group ( n = 30) and control group( n = 30), randomly. Experimental rats were harvested at 7 w, 12 w,17 w after onset of experiment and functional evaluations were performed. Histology, immunohistology were examined to investigateboth histolopathology changes and the expression of bone morphogenic protein-7 (BMP-7), transforming growth factor-β1 (TGF-β1 )and a-smooth muscle actin (α-SMA) in kidneys at three time points mentioned above, respectively. Results Compared with controlgroup, 24 h urinary protein in model group lost increasingly and significantly difference appeared at three time points relative to controlgroup ( P ＜ 0.01 ). Urinary NAG in model group was markedly higher than that in control group from 7 w after onset (P ＜ 0.01 ) andwas increasingly raised at 12 w and 17 w (P＜0.01). The value of blood BUN and Cr in model group increased at 7 w (P＞0.05) rel-ative to control group. There was significant difference at 12 w and 17.w (P ＜ 0.01 ). Histologically, kidneys in model group, at 7 w,exhibited tubular casts and gently tubular dilation, granuloma in cortex, mononuclear cells infiltration in tubulointerstitial areas, andmild interstitial fibrosis. At 12 w, the degree of tubular injury and tubulointerstitial fibrosis gradually aggravated. Up to 17 w, diffusetubular dilation or atrophy was observed and focal tubules disappear. Diffuse interstitial fibrosis was exhibited. In normal kidneys, im-munohistochemistry suggested that the light expression of BMP-7 was detected in proximal renal tubular epithelial cells and marked ex-pression was identified in distal tubule, collecting duct, and renal tubular epithelial in junction area between cortex and medulla. How-ever, the expression of BMP-7 in kidneys of model group significantly decreased with increasing tubulointerstitial fibrosis and was nega-tive correlation with the expression of TGF-β1(r = -0. 981 P＜0.01) and α-SMA (r= -0.975 P＜0.01). Bailing capsule ad-ministration protected the expression of BMP-7 and reduced TGF-β1 and α-SMA expression before 12 w(P＜ 0.01 ). Conclusions Ourstudy shows an anti-fibrotic reno-protective function of Bailing capsule in rats with tubulointerstitial fibrosis via prevention of epithelial-mesenchymal transition at early stage. However, the beneficial effect lost with increasing tubulointerstitial fibrosis.

OBJECTIVETo evaluate the feasibility of a valved stent on closure patent ductus arteriosus in a Chinese miniswine model.

METHODSSelf-expandable nitinol stents were made of Ni-Ti shape memory alloy (9 mm in diameter). Bovine pericardium was shaped and sutured onto the stents. Fluid passing test, pre-releasing test and static test of pressure in tube were performed in all devices before use. In eight Chinese miniswine, vascular grafts (PTFE vascular prosthesis) were surgically inserted between the descending thoracic aorta and pulmonary artery for establishment of patent ductus arteriosus model. Valved stents were deployed to occlude the patent ductus arteriosus. Echocardiography was performed two hours post operation. Aortic angiography was made 30 days post operation in survived animals. Animals were then sacrificed for autopsy and electron microscopy examinations.

RESULTSIn vitro testing showed that the closure of the valved stent leaflets was satisfactory and fluid flows were not restricted in the opposite direction. The valved stents could be released through catheter, expanded completely, rapidly fixed in the tube. Closure of patent ductus arteriosus was succeeded in 6 out of 8 animals. One animal died of respiratory failure 2 hours post operation, another one died of pulmonary embolism due to valved stent displacement. Resident shunt was not evidenced by echocardiography, aortic angiography and dissection examinations in the remaining 6 animals. The new endothelial tissue fully covered the pulmonary and aortic sides of patent ductus arteriosus in 4 and 3 animals respectively. The electron microscopic observation revealed endothelial coverage of dives.

CONCLUSIONThe valved stent could effectively close artificial patent ductus arteriosus in vivo with satisfactory new intima covering on both sides of patent ductus arteriosus.

OBJECTIVETo investigate clinical and imaging features of a patient with adult-onset Krabbe disease and to detect the underlying genetic mutations.

METHODSClinical and cranial MRI features of the patient were analyzed. Pathogenesis, clinical manifestation, cranial MRI features and diagnostic criteria for the disease were discussed.

RESULTSThe patient had presented asymmetric limb weakness and difficulty in walking. Electromyography suggested peripheral nerve demyelination. Cranial MRI showed increased signal intensity in white matter with involvement of the corticospinal tracts. Screening of GALC gene mutation has found the patient to be heterozygous for T1685C (Ile562Thr) and homozygous for A1921G (Thr641Ala), both of which were considered to be polymorphisms. In addition, he was heterozygous for G136T (Asp46Tyr), which had not been described previously.

CONCLUSIONClinical manifestations of adult-onset Krabbe disease may be atypical. Cranial MRI and galactocerebroside activity assay should be carried out for patients featuring chronic progressive corticospinal tract injury. An Asp46Tyr mutation probably underlies the disease in the current case.

The aqueous phase oxidation of gaseous elemental mercury (Hg(0)) by potassium persulfate (KPS) catalyzed by Ag(+) was investigated using a glass bubble column reactor. Concentration of gaseous mercury and potassium persulfate were measured by cold vapor atom absorption (CVAA) and ion chromatograph (IC), respectively. The effects of pH value, concentration of potassium persulfate and silver nitrate (SN), temperature, Hg(0) concentration in the reactor inlet and tertiary butanol (TBA), free radical scavenger, on the removal efficiency of Hg(0) were studied. The results showed that the removal efficiency of Hg(0) increased with increasing concentration of potassium persulfate and silver nitrate, while temperature and TBA were negatively effective. Furthermore, the removal efficiency of Hg(0) was much better in neutral solution than in both acidic and alkaline solution. But the influence of pH was almost eliminated by adding AgNO(3). High Hg(0) concentration has positive effect. The possible reaction mechanism of gaseous mercury was also discussed.

Chinese medicine pair (CMP) was frequently applied in traditional Chinese medicine (TCM) clinic, and its significance was shown in long-term clinical practices and many accumulated experiences. It is the unique combination of two relatively fixed Chinese medicines in TCM clinic with the basic feature and principle of TCM compatibility, is the most fundamental and the simplest form of TCM formulae with certain theory basis and combinatory reason, which is proven effective. And the unique combination is frequently used for achieving mutual reinforcement or detoxication. CMP is an intermediate point between single herb and many TCM formulae, reflecting the regularity of TCM formulae compatibility and connotation of differential treatment. This paper analyzed and summarized the basic characteristics, development process and research significance of CMP, which aims to lead the modern basic and applied research on compatibility theory of CMP.
