Twenty two patients with outlet obstructive constipation (OOC) underwent pelvic fourcontrast defecography preoperatively and postoperatively. Functional outcome and the findings on defecography were analyzed. The inconsistent signs between preoperative and postoperative defecography findings were shown in all patients. Some new abnormal findings, including 5 cases with pelvic floor hernia, 4 with cystocele, 4 with vagina prolapse, 3 with uterine prolapse,2 with rectal prolapsed and 1 with spastic pelvic floor syndrome were present in 5 patients with ineffective surgical treatment and 9 patients with effective surgical treatment. Reduced abnormal signs were showed in the 9 effective patients, but other new abnormalities appeared. The abnormal signs were reduced or disappeared in 8 obviously effective patients and there were no new abnormalities present in those patients. Results indicate that pelvic four-contrast defecography can provide valuable information for patients with OOC postoperatively.

Objective To study the imaging features and adequate interventional therapy of the diffuse type hepatic cellular carcinoma(HCC).Methods Fourteen patients with the diffuse type HCC underwent hepatic angiography and the adequate interventional therapy by TAI or TAE according to imaging appearances,blood supply and function of liver.Results ①Imaging appearances:the most common appearances of fourteen patients with the diffuse type HCC on DSA and CT included:tumor blood vessel was extensive and increased,tumor stain was extensive in left and right liver leaf(such as grain,small spot ,nodule shadows or low density area),liver enlarged obviously with liver cirrhosis,portal vein tumor thrombus,arteriopotal shunt and widespreadly scattered iodized oil,et al.②Therapeutic effect:the mean survival time of fourteen patients was 3 months,the longest survival period was 10 months and the shortest one was olny 15 days.Conclusion ①The specific appearances of the diffuse type HCC are diffuse small spot-like,frosted glass-like,double orbit-like and big liver-like.②The interventional therapeutic effect and prognosis of the diffuse type HCC are the worst than that of other type primary hepatic carcinoma.Selecting adequate interventional therapeutical plan can obviously prolong survival time of the patient.

Objective To explore DSA findings curative measures and effects of bronchial arterial embolization(BAE)of bronchiectasis with massive hemoptysis. Methods 35 patients with massive hemoptysis due to bronchiectasis were performed selective bronchial arterial DSA and BAE referring to image data of chest plain film and CT. Embolic materials were polyvinyl alcohol(PVA)and/or gelatinum sponge particles. Curative effects were followed-up for 3 months to 3 years. Results ①DSA revealed bronchial artery as being the only abnormal vessel accounted for 74.3%,bronchial artry combined with nonbronchial systemic artery as 22.9% and only non-bronchial artery involved 2.9%. Abnormal vessel number was 1 -5(mean 1.8) per case. Direct and indirect bleeding sign was displayed as 25.7% and 100% respectively. ②Curative and embolization effects were shown as 61 target vessels of 34 patients being embolized and total effective rate reaching 85.3%; of which 16 cases were adopted super-selective technique,1 case was failure of stopping bleeding for two times within 3 days,4 cases recurred within 3 months and 2 cases recurred over 3 months; with recurrent rate of 20.6%,but no serious complications such as spinal cord injury. Conclusions DSA examination and selective BAE of bronchiectasis with massive hemoptysis could provide high positive angiographic features and reliable curative effect.

OBJECTIVE:To prepare anhydrous iodine-containing or iodine-free hand-cleaning agents for use at field or water-deficient area.METHODS:An adhesive paste was made with PVA as vehicle and PVP-I as disinfector.Iodine value was taken as parameter of quality control.The adhesive-eliminating test was carried out on Escherichia coli and HBV elimi?nating and skin irritation tests were performed in rabbits.RESULTS:This preparation could eliminate bacteria by its adhesive action and had considerable disinfective action because of the ingredient iodine,however it could not eliminate HBV.No irrita?tion to skin was found.CONCLUSION:The preparation can effectively remove the dust,bacteria and viruses from the hands and is suitable for cleaning hands in conditions of wartime,training and water-deficient area.

Objective To investigate the expression of Fascin mRNA and its protein in human pancreatic carcinoma cell line and pancreatic cancer tissues and to explore the relationship between the expression of Fascin protein and the clinicopathologic parameters. Methods The expression of Fascin mRNA in pancreatic cancer cell lines (SW1990, Patu8988, BxPC3, cfPAC1) were measured by RT-PCR and the expression of Fascin protein in 54 samples of pancreatic career tissues and 42 adjacent normal pancreatic tissues was detected by immunohistochemical method. Results The expression of Fascin mRNA was confirmed in 3 of 4 pancreatic cancer cell lines (SW1990, Patu8988, cfPAC1), but not in the cell line of BxPC3; the rate of positive expression of Fascin protein in pancreatic cancer tissues was 64.81% (35/54) and there was no positive expression in adjacent normal pancreas tissues; the expression of Fascin protein correlated with the differentiation degree (P < 0.01) and with the lymphatic metastasis of the carcinoma (P <0.05), but not with the size and distant metastasis of the carcinoma (P > 0. 05). Conclusions Fascin protein was highly positively expressed in pancreatic cancer tissues, and the expression of Fascin protein may help diagnose pancreatic, carcinoma and predict the malignant degree.

ObjectiveTo study the reasons and mechanism of cardiomyocyte apoptosis in chronic heart failure by using Losartan and to provide a theoretical basis for the treatment of chronic heart failure. Methods The models of chronic heart failure were produced by injecting Adriamycin and Losartan as intervention agents, the expression of apoptotic protein Bax, Bcl-2 and channel protein ERK1, JNK1 and P38MAPK were detected by immunohistochemistry and RT-PCR.Cardiomyocyte apoptosis and myocardial ultrastructure are detected by transmission electron microscopy and TUNEL staining.Results Compared with the model group of heart failure, after Losartan treatment, the ultra structure of myocardial cells were significantly improved, Apoptosis index was decreased significantly (P <0.01), The level of Bax and JNK1 decreased (Bax χ~2=6.6149, P=0.0078; JNK1 q=22.0156,P<0.01). However, the expressions of ERK1 and Bcl-2 were significantly increased (ERK1 q=15.3514,P<0.01;Bcl-2 χ~2=6.81,P=0.0074).Conclusion The effect of Losartan on chronic heart failure is related closely with the pathway of ERK1 and JNK1, and no p38 MAPK pathway.

Skeletal muscle possesses a remarkable ability for its regeneration and injured tissue repair. This ability depends on the activity and contributions of muscle satellite cells. Proliferating satellite cells, termed myogenic precursor cells or myoblasts, are activated and driven out of their quiescent state upon muscle injury. In this summary, we present a review to summarize the molecular regulation in skeletal satellite cells to light on the satellite cells' self-renewal mechanism.

AIM To study oridonin induced apoptosis in human leukemia HL 60 cells. METHODS Cell morphology, agarose gel electrophoresis and flow cytometry were used. RESULTS Oridonin had significant apoptotic inductive effect on HL 60 cells in both concentration and time dependent fashion. The marked morphological changes including condensed chromatin, nuclear fragmentation and apoptotic body were observed. Typical DNA ladder in agarose gel electrophoresis and pre G 1 peak in flow clytometric analysis were also observed in the cells exposed to Ori. CONCLUSION Oridonin can induce apoptosis in human leukemia HL 60 cells.
