Objective To study the clinical significance of partial splenic embolization (PSE) for the treatment of hypersplenism and the relationship between the therapeutic effect and the area of embolization. Methods Sixteen patients with hypersplenism were divided randomly into two groups: Group 1 (n=5) and Group 2 (n=11). The embolization area in Group 1 was 40%-59% and that in Group 2 was 60%-80%. A follow-up for 1 year was conducted in all patients. Results The short-term effective rates (CR+PR) of thrombocyte count were 81.3% in Group 1 and 93.8% in Group 2, respectively, whereas the long-term effective rates were 62.5% and 87.5%, respectively, and the corresponding one-year recurrence rates were 23.1% and 6.7%. The long-term effective rates of WBC count were 71.4% and 82.2% in groups 1 and 2, respectively, and the one-year recurrence rates were 28.6% and 17.8%, respectively. The long-term effective rates of RBC count were 70% in Group 1 and 83.3% in Group 2, respectively, and the one-year recurrence rates were 22.2% and 11.8 %, respectively. Conclusion PSE, resulting in a low recurrence rate, is effective in treating hypersplenism.

Objective To study the phosphatidylinositol 3-kinase (PI3K) and protein kinase B (Akt) expression and clinical significance in the tissue of epithelial ovarian cancer (EOC).Methods Western Blot and immunohistochemical staining were applied to investigate the expression of PI3K and Akt in specimens of 41 patients with EOC (EOC group),20 patients with normal ovary (NO,NO group) and 20 patients with benign epithelial ovarian tumor (BEOT,BEOT group).Results The positive expression rate of PI3K in EOC group [70.7％(29/41)] was significantly higher than that in NO group and BEOT group [10.0％ (2/20),20.0％ (4/20)] (P ＜0.01).The positive expression rate of Akt in EOC group [73.2％ (30/41)] was significantly higher than that in NO group and BEOT group [10.0％ (2/20),30.0％ (6/20)] (P＜ 0.01).There was significant difference in the expression of PI3K and Akt between Ⅰ-1Ⅱ stage and Ⅲ-Ⅳ stage in EOC patients (P ＜ 0.05).There was no significant difference in the expression of PI3K and Akt between serous cystadenocarcinoma and mucous cystadenocarcinoma (P ＞ 0.05).Conclusions The expression of PI3K and Akt increases obvioualy in the tissue of EOC.PI3K and Akt may play important roles in carcinogenesis and metastasis of EOC.PI3K/Akt pathway may be served as a potential target for anticancer therapy.

Objective To explore the value of prenatal ultrasound in diagnosis of fetal anomalies of the inferior vena cava (IVC) and to improve the prenatal detection rate.Methods Fourteen cases of fetal anomalies of IVC examined by prenatal ultrasound from June 2013 to April 2016 in our hospital were analyzed,the prenatal ultrasonographic characteristics through abdominal transverse,coronal and IVC long axis were summarized,and were compared with the autopsy results.Results In 14 cases of anomalies of IVC,12 cases were isolated IVC interruption,and 2 cases were high confluence of IVC.In 12 cases of isolated IVC interruption,9 cases compicated by left isomerism,1 case complicated by sistus inversus viscerum,1 case complicated by isolated IVC interruption;2 cases of high confluence of IVC were combined with multiple malformations,including 1 case of chromosome 18-trisomy syndrome.Thirteen cases were confirmed by pathology,and 1 case of the high confluence of IVC lost follow-up.Conclusions Fetal anomalies of IVC have characteristic manifestations in prenatal ultrasonographic.When detecting the IVC interruption,left isomerism should be highly suspected.

Objective To observe the food intolerance of irritable bowel syndrome with diarrhoea(IBS-D) patients and healthy physical examinees and the clinical effect of the treatment of IBS-D food rejectingtrend.Methods Sixty-eight cases IBS-D patients meeting the diagnostic criteria of RomeⅢ were selected and 40 cases of healthy as control group,tested 14 kinds of food specific IgG antibody by enzyme-linked immunosorbent assay,treated the IBS-D patients with food intolerance for 12 weeks by the application of food rejectingtrend and observed the change of main symptoms.Results Among the 68 cases of IBS-D patients,55 cases had at least one of food intolerance,the positive rate was 80.88%;the control group had 13 cases of food intolerance,the positive rate was 32.50%,the difference between the two groups was statistically significant(χ2=25.28,P<0.01).The food with the highest positive rates of two groups were both wheat,egg white/egg yolk,milk and soybean.After 12 weeks of diet treatment,the total score of the symptoms of IBS-D patients decreased from (8.25±2.97) points to (3.13±3.52) points(t=11.107,P<0.01),self scores of the degree 0and frequency of abdominal pain,frequency of diarrhea,degree of abdominal distension,stool shape and general feelings of distress were significantly improved compared with that before treatment(t=12.429,11.016,5.685,5.558,7.681,11.065,P<0.01).Among 54 cases IBS-D patients(1 patient lost to follow-up),61.11%(33/54) significantly improved,24.07%(13/54) improved,14.81%(8/54) invalid,the total effective rate was 85.19%(46/54).Conclusion There is correlation between food intolerance and IBS-D.According to the Results of the detection of food specific IgG antibody,food rejectingtrend treatment can effectively improve the symptoms of IBS-D.
