ObjectiveTo evaluate the efficacy of modified ultrafiltration (MUF) combined with conventional ultrafiltration (CUF) for cardiac valve replacement in patients with severe valve disease.MethodsOne hundred and eight NYHA Ⅲ or Ⅳ patients with severe valve disease,aged≥ 18 yr,weighing 50-80 kg,scheduled for elective cardiac valve replacement under cardiopulmonary bypass (CPB) were randomized into CUF group ( n =56) and CUF combined with MUF group (CMUF group,n =52).MUF was performed at the end of CPB,and the flow and time was 400 ml/min and 15-20 min respectively.Arterial blood samples were taken for blood gas analysis and for measurement of the plasma IL-6 and IL-8 concentrations after induction of anesthesia (T1),at the beginning of CUF (T2),at the end of GUF (T3),at the beginning of MUF (T4),at the end of MUF (T5),and at 2,8 and 24 h after the termination of CPB (T5-8).The oxygenation index was calculated and the airway pressure was recorded at T5 8.The amount of urine output during operation,the amount of urine output and volume of chest tube drainage within 24 h after operation,extubation time,packed red blood cell (PRBC) transfusion and duration of stay in ICU were recorded.ResultsCompared with CUF group,the hematocrit at T5,6 and oxygenation index at T7,8 were significantly increased,extuhation time was significantly shortened,and the amount of urine output and volume of chest tube drainage within 24 h after operation and PRBC transfusion were significantly reduced ( P ＜0.05),and no significant change was found in the plasma IL-6 and IL-8 concentrations,airway pressurc,amount of urine output during operation,and the duration of stay in ICU in group CMUF ( P ＞ 0.05).ConclusionCombination of MUF and CUF during CPB can be used for cardiac valve replacement in patients with severe valve disease,improve the function of organs after operation and reduce homologous blood transfusion.

Objective To investigate the clinical effect of superselective arterial infusion chemotherapy(SACT) and embolization in advanced cervical carcinoma patients before surgery. Methods 26 previously untreated patients with stage ⅡA-Ⅳ cervical carcinoma admitted from January 2004 to March 2008 were enrolled into the study, patients underwent SACT of the internal iliac artery(dose of the drug: CBP 80 rag, VCR 2 rag, MMC 16 mg) by Seldinger technique in the surveillance of DSA, the obvious branches of the tumor blood supply were embolized by gelfoam particles. Size of tumor before and after chemotherapy was measured by gynecological examination combined with B ultrasonic examination and CT, then calculated the percentage of tumor regression. Radical hysterectomy was administered one month after chemotherapy. Results 24 patients were evaluated as PR, the reaction rate of chemotherapy was 92.3 %. Conclusion SACT before surgery can effectively reduce tumor volume, decrease lymphatic metastasis and subclinical dissemination and enhance the opportunity of radical hysterectomy, and to improve the quality of life and OS of the advanced cervical carcinoma patients.

Objective To investigate the effect and mechanisms of the Berberine on the human breast adenocarci-noma cell line MCF-7 . Methods MTT method was used to evaluate the proliferation effect of MCF-7 and the per-centage of apoptotic cells were determined by flow cytometric analysis. The expressions of JAK2, p-JAK2, p-STAT3, STAT3, Bax, Bcl-2, Cleavage-PARP and Cleavage-Caspase3 were detected by Western blotting. Results The results showed that BBR treatment decreased the activation of JAK2/STAT3 signal pathway and up-regulated the expression of Bax, Caspase3 and PARP activation with the decrease of the expression of Bcl-2. Wherefore, ex-pression of the constitutively active form of STAT3 could attenuate the effect of BBR on the MCF-7 cell. Conclusion Berberine can induces apoptosis and proliferation inhibition of breast adenocarcinoma cell lines of MCF-7 through inhibition of the JAK2/STAT3 signaling pathway.

Objective To explore the relation between thyroid nodular and thyroid calcification .Methods The clinical data of 430 cases with nodular goiter admitted from January 2011 to December 2013 were reviewed.All cases were performed ultrasonography and pathologic examination .Results Of 430 cases,there was thyroid carcinoma in 49 cases(11.4%),including microcalcification in 30 cases(61.2%) and macrocalcification in 3 cases(6.1%);benign lesion in 381 cases(88.6%),including microcalcification in 24 cases(6.3%) and macrocalcification in 39 cases(10.2%).The difference was remarkable (P=0.000).There was remarkable difference in malignant calci-fied nodules ratio between the patients with microcalcification and macrocalcification (55.6%vs 7.1%,P=0.000), between the patients aged 45 years below and above(48.8%vs 22.6%,P=0.007),between the patients with solita-ry and multiple nodules(45.0%vs 16.7%,P=0.005).But there was no statistic difference in malignant calcified nodules ratio between the male and female groups (24.2% vs.39.7%,P=0.130).Conclusion Microcalcification is a highly specific sign to predict thyroid carcinoma in ultrasonography exam .Positive intervention will be performed immediately when calcification appears in thyroid nodules .
