Objective To compare the clinical curative effect of partial hepatectomy combined with biliary intestinal anastomosis and T tube drainage in the treatment of intrahepatic stones.Methods 72 patients with intrahe-patic stones were selected and randomly divided into observation group and control group.The observation group received lobectomy of liver +bile duct jejunum anastomosis,the control group received lobectomy of liver +T tube drainage treatment.The operation time,intraoperative blood loss,functional exercise time,length of hospital stay, recurrence rate,clinical efficacy and complications were observed.Results The patients were followed up for 6 -12months.The operative time,blood loss,ambulation exercise time,length of hospital stay in the observation group were (158.29 ±32.53)min,(161.42 ±11.75)mL,(3.61 ±0.28)d,(5.31 ±1.17)d,which were significantly more than those in the control group[(127.57 ±26.38)min,(78.29 ±8.36)mL,(2.25 ±0.56)d,(4.86 ± 2.39)d].The recurrence rate of stone of the observation group during the postoperative follow -up was 5.56%, which was significantly lower than 16.67% of the control group (t =4.328,7.196,2.174,2.259,1.862,all P <0.05).The excellent and good rate of the observation group was 94.44%,which was higher than 83.33% of the control group,the difference was statistically significant (χ2 =1.257,P <0.05).6 cases in the observation group had complications (16.67%),including 1 case of incision infection,subphrenic infection in 2 cases,bile leakage in 2 cases,1 case of pulmonary infection.15 cases in the control group had postoperative complications (41.67%), including 3 cases of wound infection,bile leakage in 4 cases,3 cases of biliary tract bleeding,abdominal bleeding in 1 case,2 cases of pulmonary infection,subphrenic infection in 1 case,pleural effusion in 1 case,the difference between the two groups was significant (χ2 =2.291,P <0.05).Conclusion Liver resection is an effective method for treatment of intrahepatic bile duct stones,on the basis of liver resection by intestinal anastomosis in the treatment of intrahepatic bile duct stone long -term effect is better,which can effectively prevent recurrence of the intrahepatic bile duct stone and bile duct cancer,widely used in patients with indications for clinical physicians.

Objective To study the mechanism of multicellular drug resistance of pulmonary adenocarcinoma cell line A549 mediated by cell-cell adhesion. Methods We compared the sensitivity of monolayer cells (MCs) to adriamycin (ADM) with that of multicellular spheroids (MCSs) which was employed as a three dimensional cell culture model. Transmission electron microscopy was applied to observe the cellular ultrastructure. Bcl-2, Bcl-xL, and Bax expression levels were detected by flow cytometry and indirect immunofluorescent staining. Results Compared with MCs, MCSs had more than two layers of cells, more extensive and compact cell adhesion, and inlay junctions were found within them. MCSs were more resistant to ADM. At the same time, Bcl-2 and Bcl-xL expressions in MCSs were much higher. After treatment with ADM, expressions Bcl-2 and Bcl-xL increased markedly in MCSs. Conclusion MCSs could simulate the solid tumors in vivo and has multicellular drug resistance mediated by cell-cell adhesion. The possible mechanisms may be associated with the upregulation of Bcl-2 and Bcl-xL.

Purpose To investigate the value of 3.0T MR T1ρquantitative analysis in early detection of disc degeneration. Materials and Methods Conventional T2WI and T1ρwere collected in 35 healthy volunteers (male 16, female 19) on 3.0T MRI, and the classification of disc nucleus was performed by Pfirrmann classification. T1ρvalue of nucleus pulposus was measured and analyzed for the relationship among Pfirrmann classification, segmental and gender. Results There was a significant negative correlation between T1ρvalue and Pfirrmann grade (r=-0.542, P<0.001). T1ρvalue in L5/S1 segment (94.80±26.60) ms was significantly lower than that in L2/L3 (117.18±25.64) ms and L3/L4 (115.52±28.53) ms (P<0.01), and there was no significant difference among other segments (P>0.05);there was no gender differences among the T1ρvalue of each segment (t=0.006, 0.042, 0.797, 1.022, 0.038, P>0.05). Conclusion T1ρ value is closely related to the degree of disc degeneration, and T1ρimaging can be used as an objective, sensitive and effective tool for early detection of disc degeneration.

OBJECTIVE:To standardize periooperative prophylactic application of antibiotics. METHODS:According to the characteristics of orthopaedic and parenchyma surgery,classifying evaluation table of typeⅠincision infection risk was designed sci-entifically and rationally. The individual application of antibiotics in surgery patients had been achieved through infection risk evalua-tion. High risk typeⅠincision patients used antibiotics rationally and low risk patients seldom used or didn’t use at all. RESULTS:Through using infection risks classifying table,the rate of antibiotics prophylactic application in typeⅠincision drops from 74.10%to 28.68%,and and the per capita duration of antibiotics prophylactic application shortened from 4.23 d to 2.21 d. The postopera-tive infection rate remained the same. CONCLUSIONS:Through infection risk classifying evaluation,individual application of anti-biotics can be achieved in surgery patients,so as to promote rational use of antibiotics for prophylactic use,reduce antibiotics dos-age and antibiotics abuse under the condition of controllable surgery infection.

Objective To explore an optimal model of three dimensional in vitro cell culture for simulating solid tumors in vivo . Methods The model of three dimensional cell culture was constructed under the conditions of inhibiting the cell wall attachment and stirring the medium. Multicellular spheroids (MCS) were cultured using microcarriers (CutiSpher). Drug sensitivity of monolayer cells (MC) and MCS was tested by MTT staining and cytometry, respectively. Ultrastructures of the MC and MCS were observed by transmission electron microscopy. Results Cells in three dimensional cell culture model without microcarriers were compacted into mass at 4 d while cells in MCS were found to attach to the microcarriers at 0.5 h. MCS had more than two layers of cells growing within it at 5 d. Compared with MC, MCS was more resistant to the anticancer drug, and had more plenty of organell and microvilli with more extensive and compact cell adhesion. Conclusion MCS has strong developmental properties and can simulate the cell cell interactions in vivo , especially cell adhesion, which may contribute to the drug resistance of MCS.

Objective To observe the effects of psychological supportive therapy on the activities of daily living (ADL) and depression after cerebral hemorrhage. Methods 60 cases with mild or medium depression according to 17 items Hamilton Rating Scale for Depression (HAMD-17) after cerebral hemorrhage were divided into treatment group (n=30) and control group (n=30). All of them accepted physical exercise, and those in the treatment group accepted psychological supportive therapy in addition. They were assessed with Functional Independence Measure (FIM) and HAMD-17 before and after the treatment. Results After 2 months of treatment, the score of FIM increased more in the treatment group than in the control group (P<0.001), and the score of HAMD-17 decreased (P<0.001). Conclusion Psychological supportive therapy may promote the recovery of ADL and depression for patients post cerebral hemorrhage.
