ABSTRACT
Objective To analyze and compare the values of applying color Doppler ultrasound in the diag -nosis of testicular torsio and acute epididymo -orchitis.Methods 90 males in our hospital were selected and divided into the testicular torsion group and acute epididymo -orchitis group ,color Doppler ultrasound was applied in the two groups.Results After examination by color Doppler ultrasound ,it showed that there were significant differences in blood supply of testicle ,epididymis between the two groups ,the diagnostic result was accurate with statistical signifi-cance(χ2 =11.408,11.944,P<0.05).Conclusion It can highlight the images and blood supply features of testic-ular torsion and acute epididymo -orchitis that applying color Doppler ultrasound ,and as an economic ,practical ,accu-rate and non-invasive examination ,it can diagnose testicular torsion and acute epididymo -orchitis accurately ,so it's the preference for testicular torsio and acute epididymo -orchitis.
ABSTRACT
Objective To investigate the application value of plasma D-dimer and coagulation indicators in the patients with o-varian cancer by detecting the routine coagulation indicators and plasma D-dimer level.Methods The plasma D-dimer and coagula-tion indicators levels were measured in 84 patients with ovarian cancer and 25 patients with benign ovarian tumor.The application value of preoperative plasma D-dimer level in monitoring the disease course of ovarian cancer was evaluated.Results The plasma levels of D-dimer and FBG in the ovarian cancer group were significantly higher than those in the ovarian benign tumor control group(P <0.01);moreover the plasma levels of D-dimer and FBG in the patients with the stage Ⅲ~Ⅳ ovarian cancer were signifi-cantly higher than those in the patients with the stageⅠ~Ⅱ ovarian cancer,the differences had statistical significance(P <0.05), which prompting that the coagulation and fibrinolysis dysfunction in the patients with ovarian cancer exhibited the aggravating trend with the disease condition progression.Conclusion D-dimer may reflect the excessive activation of fibrinolysis function in ovarian tumor,which prompting the survival period and prognosis in the patients with advanced ovarian cancer.The plasma D-dimer level has the important significance to early prevention,early diagnosis,early treatment and improve the prognosis in the thrombosis oc-currence in ovarian cancer.
ABSTRACT
[Objective]This study was designed to investigate capability of the conditioned media that originated from Renca cells to convert CIM~+ CD25~- T cells into CD4~+ CD25~+ T cells,which can exert immunosuppressive effect on effector T cells in vitro and in vivo.[Methods]The common media were mixed with the conditioned media at different ratios,and fresh enriched CD4~+ CD25~- T cells with MACS were cultured in mixed media for 7 days.At end-point of culture,the cells were collected and detected phenotypes in flow cytometer.Moreover,we detected immunosuppressive effect of converted CD4~+ CD25~+ T cells on effeetor T cells proliferation in one-way mixed lymphocytes reaction by using CCK-8,and we observed survival time and histology of grafts.The delayed type hypersensitivity was determined 14 days after transplantation.[Results]The mixed media could increase ratio of CD4~+ CD25~+ Foxp3~+ T cells in conditioned media ratio-dependent(P＜0.05),compared with control groups,when the mixed media contained no mote than 75% of conditioned media.The converted CD4~+ CD25~+ T cells significantly suppress proliferation of effector T cells in vitro,and prolong survival time of grafts,which were(29.6±1.4)d in converted CD4~+ CD25~+ T cells treated groups(P＜0.05),compared with that in untreated groups(9.8±0.6 d)or PBS treated groups(10.9±0.6 d).Moreover,delayed-type hypersensitivity reaction were conducted at day 14 after transplantation in the recipients,and the results showed that less pad swelling in the group treated with converted CD4~+ CD25~+ T cells than other control groups was found,according to measurement of pad swelling.In addition,progressed to complete necrosis of grafts were exhibited in the mice treated with PBS and untreated mice,whereas better healing of grafts and less lymphocytes infiltration were displayed in the mice treated with converted CD4~+ CD25~+ T cells,which were similar to the mice treated with natural regulatory T cells.[Conclusion]The converted CD4~+ CD25~+ T cells with Renca conditioned media play suppressive role in vitro and in vivo.
ABSTRACT
Forty-three cases of malignant tumors with metastases to serous cavites were treated by interventional chemotherapy under ultrasound guidance and monitoring. 43 cases (83 injections) were all successfully operated and followed up. After peritoneoclysis, besides the common side effects of chemotherapyie nausea and vomiting, 3. 8% of the patients had abdominal pain and 75. 5% had abdominal distention. No complication of hemorrhage, infection, drug leakage or organ injury oceurred. It is suggested the method is safe easily to be used especially for the intracavitary chemotherapy of malignaant tumors and deserves to be widely employed.
