BACKGROUND:Bladder acellular matrix graft (BAMG) is frequently used for domains of tissue engineering scaffold due to its great biocompatibility and cell adhesion. OBJECTIVE:To verify the biological characteristics of BAMG after frozen and lyophilized processing. DESIGN,TIME AND SETTING:A biocompatibility experiment was performed at Shanghai Tissue Engineering Research and Development Center and Experimental Animal Department of the Sixth People's Hospital of Shanghai between May and November 2008. MATERIALS:Two New Zealand rabbits were used in this study for BAMG preparation. METHODS:After midsection of rabbit bladder,mucous membrane of urinary bladder was isolated and dipped in three-distilled water for 24 hours. Thereafter,the samples were incubated with acellular solution containing 0.1% Triton X-100 and 0.15% aqueous ammonia for 14 days. The culture medium was changed regularly. The samples in the control group were stored in 75% ethanol,while samples in the experimental group were frozen for 24 hours at -80 ℃,vacuum-dried for 24 hours,and stored in 75% ethanol. MAIN OUTCOME MEASURES:Biological characteristics of BAMG were detected using hematoxylin and eosin staining,Masson staining,and scanning electron microscopy; biological characteristics were compared between the two groups using cell adhesion test,MTT assay,and subcutaneously embedding test. RESULTS:Hematoxylin and eosin staining and Masson staining revealed that no residual cells were detected in the BAMG,and collagen was intact. Scanning electron microscopy demonstrated that cells exhibited a slit-shaped structure mainly containing collagen which was beneficial for cell adhesion. Mechanical test revealed that the BAMG after frozen and lyophilized processing not only reserved the mechanical properties of the raw BAMG,but also had a great elongation. MTT assay confirmed that cytotoxicity was grade 0,and BAMG had a good compatibility to smooth muscle cells. After subcutaneously embedding for one month,BAMGs had good adhesions to subcutaneous tissues,and muscular adhesion and vascular proliferation were observed. CONCLUSION:BAMG after frozen and lyophilized processing reserves original biocompatibility and has great elongation; therefore,it will become a useful and ideal biomaterial for tissue engineering scaffold.

Objective To investigate the relationship between acute biliary pancreatitis (ABP) and anomalous pancreaticobiliary duetal union (APBDU). Methods 131 patients with ABP were enrolled to test the serum total bilirubin (TB), alanine amintransferase (ALT), aspartate amintransferase (AST), alkaline phosphates (ALP), γ-glutamyl transferase (γ-GT). All the patients received medical treatment, and then these tests were performed again. Thereafter, all the patients underwent selective surgery and intra-operative cholangiography was performed to observe the pancreaticobiliary duetal union. Results 27 patients (20.6%) with APBDU were found in 131 patients. Among them, 8 cases (29.6%) was B-P subtype (TypeⅠ), 16 cases (59.3%) was P-B subtype (TypeⅡ) , and the remaining 3 cases was mixed subtype (TypeⅢ). A significant decrease of ALT, AST, ALP, γ-GT after non-surgical treatment in both group of APBDU and NAPBDU was noted (P<0.05). The serum levels of ALT, AST,γ-GT in APBDU patients were (71.81± 23.19) U/L, (47.85±27.87) U/L, (52.86±31.49) U/L, respectively; and in NAPBDU patients were (51.96±15.40) U/L, (40.77±16.58) U/L, (34.86±26.47) U/L. The difference was statistically significant (P<0.05). Condusions APBDU is an important etiology of ABP.

Purpose To establish rabbit VX2 tumor model and to explore the relation between perfusion parameters and the expression of the VEGF in the portal vein VX2 implanting tumor emboli. Materials and Methods VX2 tumor was implanted in the portal vein of eight experimental rabbits. Multi-slice CT (MSCT) perfusion scan was performed after tumor formation to measure and compare portal vein tumor thrombus, hepatic blood lfow (HBF) near tumor foci and far away from tumor foci, hepatic blood volume (HBV), probability of surface area product (PS) and mean transit time (MTT). The VX2 tumor emboli were then resected to analyze the relationship between the liver perfusion parameters and VEGF expression using immunohistochemical method. Results MSCT liver perfusion parameters were not statistically signiifcant between foci close to or far away from the tumor (P>0.05). The HBF, HBV and PS within the tumor emboli were higher than that in hepatic parenchyma (P<0.05) and the MTT was higher (P<0.05). There was positive correlation (r=0.711, 0.646 and 0.626, P<0.05) between the HBF, HBV and PS of portal vein VX2 tumor emboli and VEGF expression, and there was negative correlation between MTT and VEGF expression (r=-0.565, P<0.05). Conclusion MSCT perfusion parameters in the portal vein VX2 implanting tumor emboli and the expression of VEGF are positively related. MSCT can evaluate the angiogenesis of portal vein VX2 implanting tumor emboli.

OBJECTIVETo compare the clinical therapeutic effects on intractable facial paralysis among acupuncture, acupoint catgut embedding and PDS embedding.
METHODSTwo hundred and seventy-nine patients of intractable facial paralysis were randomized into an acupuncture group, a catgut embedding group and a PDS embedding group, 93 cases in each one. Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Xuanlu (GB 5), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Qianzheng (Extra), Xiaguan (ST 7) and Fengchi (GB 20) on the affected side and bilateral Hegu (LI 4) and Zusanli (ST 36) were selected in the three groups. In the acupuncture group, acupuncture was applied to those acupoints, once every two days; 10 treatments made one session; the successive three sessions were required. In the catgut embedding group and the PDS embedding group, catgut and PDS were embedded separately, once every 10 days; 3 treatments made one session and the successive two sessions were required. The therapeutic cycle was 2 months in the three groups. The therapeutic results were analyzed statistically 2 months later. The scores of Sunnybrook facial nerve grading system and the facial nerve electroneurography (ENoG) were used for the efficacy assessment before and after treatment in the three groups.
RESULTSAfter treatment, the score of Sunnybrook facial nerve grading system was improved apparently after treatment as compared with that before treatment in any of the three groups (all P < 0.05). The score in either of the embedding groups was better than that in the acupuncture group (both P < 0.05). The difference was not significant between the catgut embedding group and the PDS embedding group (P > 0.05). After treatment, ENoG wave ampli tude values in the frontal muscle and orbicularisoris muscle on the affected side were improved as compared with those before treatment in the three groups (all P < 0.05). Those in the catgut embedding group and the PDS embedding group were better than those in the acupuncture group (all P < 0.05), and had no significant difference as compared with those on the healthy side (P > 0.05). In the acupuncture group, ENoG wave amplitudes on the affected side were lower than those on the healthy side (both P < 0.05).
CONCLUSIONAcupuncture, catgut embedding and PDS embedding at acupoints all achieve the therapeutic effects on intractable facial paralysis. However, the acupoint embedding therapy presents more advantages on the recovery of facial nerve function. The efficacy is similar between the catgut embedding and the PDS embedding.
