Objective To evaluate ascending venography in the diagnosis of iliac vein compression syndrome.Methods From April 2011 to April 2013,we have had 556 patients with varicose veins suspected of Cockett syndrome.The degree of varicose veins by the International Union of Venous Clinical Classification (CEAP classification) was as following[1]:shallow varicose veins of lower limb (C2) in 190;varicose veins with limb swelling (C3) in 149 cases ; with body skin changes,such as pigmentation,eczema or lipid hard skin disease (C4) in 130; with healed ulcers (C5) in 17; with active ulcer(C6) in 70.Deep vein anterograde contrast and femoral venous cannula angiography were performed on 760 times.Results Iliac vein compression syndrome (Cockett) was detected by ascending venography in 154 patients,the diagnosis was established by following femoral venous cannula angiography.In the other 48 patients in whom Cockett syndrome was suspected by ascending venography,final diagnosis was reached by femoral venous cannula angiography.Altogether there were 202 iliac vein compression syndrome cases,with a positive rate 38.19％ (202/529).The narrowness was larger than 50％ in 173 cases.In 145 cases there were visible collateral vessels.Conclusions Deep vein ascending angiography is a useful screening method in the diagnosis and treatment of Cockett syndrome.

Objective To investigate the effect of proteasome inhibitor MG132 on the proliferation of human lens epithelial cells SRA01/04. Methods The SRA01/04 cells were treated with MG132 by different concentrations (0, 0. 1, 0. 5, 1. 0, 2. 5, 5.0, 10. 0μmol/L) for 36 hours. The cell viability in all groups was determined using methylthiazoltetrazolium (MTT) test. The effect of MG132 on the apoptosis and regulation of cell cycle about SRA01/04 cells were detected by flow cytometry (FCM). The SRA01/04 cells treated with MG132 were observed after Annexin V/FITC-PI staining by fluorescence microscope. Results The inhibitory effect of MG132 on SRA01/04 cells proliferation was enhanced with the increase of MG132 concentration. The 50% inhibiting concentration ( IC50 ) of MG132 was 2. 50μmol/L after SRA01/04 cells were treated with MG132 for 36 hours. The apoptosis index of the cells treated by MG132 at 2. 5μmol/L and 5 μmol/L for 36 hours was 6. 55 ± 0. 35% and 13.75 ± 3.18%, and 0. 75 ± 0. 21% for 5.0μmol/L for 36 hours in control group. After cells were treated with MG132 for 48h, the percentages of cells at G0/G1 phase were (42. 57 ± 0. 64) %, (73.42 ± 3.10) %, ( 80. 95 ± 3.83 ) % 0, 2. 5,5.0 μmol/Lgroups respectively, and those at S phase were (49. 44±1.36)%, ( 17. 40 ± 1.50)%, ( 19. 57 ± 1.29)%.Annexin V/FITC-PI staining was used, and MG132 was found to result to apoptosis. Conclusions MG132 could inhibit the proliferation of SRA01/04 cells by the effect of inducing apoptosis and regulation of cell cycle. The proteasome inhibitor-might play a key role in the prevention of posterior capsular opacification.

Objective: To observe the clinical efficacy of umbilicus application with Chinese medicine in treating children’s chronic diarrhea due to food intolerance and the value of healthy diet education. Methods:Eighty kids with chronic diarrhea due to food intolerance were recruited from multiple centers and divided by using the random number table into a treatment group of 40 cases and a control group of 40 cases. For both groups, based on the level of serum food-specific immunoglobulin G (Ig-G), the patients were given unified diet following the healthy diet guidance: safe, alternate, and forbidden, while the treatment group was additionally given umbilicus application with Chinese medicine. The therapeutic efficacy and symptom score of traditional Chinese medicine (TCM) were observed and compared respectively after 1-week, 2-week, 4-week, and 12-week treatment. Results:The diarrhea symptoms and coupled symptoms scores dropped significantly in the two groups after treatment ( all P<0.05), and the inter-group comparisons also showed statistical significances (P<0.05). The total effective rate was 97.5% in the treatment group versus 77.5% in the control group, and the inter-group difference was statistically significant (P<0.05). Conclusion:The healthy diet guidance based on the food intolerance test is effective in helping treat diarrhea, while umbilicus application with Chinese medicine works better in treating diarrhea for kids with chronic diarrhea due to food intolerance and can significantly enhance the therapeutic efficacy.

OBJECTIVETo evaluate whether intraoperative autologous donation (IAD) can reduce perioperative blood transfusion for patients underwent mitral valve replacement (MVR).

METHODSA total of 318 patients received implementation of IAD from January 2011 to December 2013 were analyzed retrospectively, and compared with 517 patients of the previous 36-month period (from January 2008 to December 2012). The method of small-volume retrograde autologous priming, strict blood transfusion standard along with IAD together constituted a progressive blood-saving strategy. Statistical methods including Students' t-test, Pearson's χ(2) test, Kruskal-Wallis analysis and multivariate Logistic regression model were used for comparisons of the data.

RESULTSThere were no significant difference between IAD group and non-IAD group considering preoperative patient demographics, characteristics and preoperative comorbidities. However, IAD group significantly reduced number of patients transfused with intra/post-operative packed red-blood cell (PRBC) (55(17.0%) vs. 215 (42.1%), χ(2)=53.0, P=0.000), and had significantly reduced postoperative chest tube output (150(380) ml vs. 700(660) ml, H=195.648, P=0.000), length of stay ((16±6) d vs. (20±8)d, t=9.60, P=0.000). But hematocrit were lower in IAD group (30%±5% vs.33%±4% at end of operation, t=7.76, P=0.000; 30%±4% vs. 32%±5% at discharge, P=0.000, t=3.86). Multivariate logistic aggression analysis revealed that age, IAD and smoking history were factors influencing the probability of intra or postoperative blood transfusion.

CONCLUSIONImplementation of blood conservation strategies based on intraoperative autologous donation in mitral valve replacement surgery can significantly reduce intra/postoperative blood transfusion as well as postoperative complications.

Purpose: Real-time detection and intervention can be used as potential measures to markedly decrease breast cancer mortality. Assessment of circulating tumor DNA (ctDNA) may offer great benefits for the management of breast cancer over time. However, the use of ctDNA to predict the effectiveness of neoadjuvant treatment and recurrence of breast cancer has rarely been studied. Methods: We prospectively recruited 31 breast cancer patients with 4 subtypes. Three time points were set in this study, including before any therapy (C1), during surgery (T), and six months after surgery (C2). We collected peripheral blood samples from all 31 patients at C1, tumor tissue from all 31 patients at T, and peripheral blood samples from 25 patients at C2. Targeted 727-gene panel sequencing was performed on ctDNA from all blood samples and tissue DNA from all tissue samples. Somatic mutations were detected and analyzed using a reference standard pipeline. Statistical analysis was performed to identify possible associations between ctDNA profiles and clinical outcomes. Results: In total, we detected 159, 271, and 70 somatic mutations in 30 C1 samples, 31 T samples, and 12 C2 samples, respectively. We identified specific genes, such as PIK3CA, TP53, and KMT2C, which were highly mutated in the tissue samples. Furthermore, mutated KMT2C observed in ctDNA of the C2 samples may be an indicator of breast cancer recurrence. Conclusion Our study highlights the potential of ctDNA analysis at different timepoints for assessing tumor progression and treatment effectiveness, as well as prediction of breast cancer recurrence.

Male breast cancer (MBC) is rare and accounts for approximately 1% of all breast cancer cases worldwide. Previous studies have suggested that several factors significantly increase the risk of MBC. Prolactinoma has the highest incidence rate among patients with functional pituitary tumors. However, whether prolactinoma is involved in the onset and progression of breast cancer remains unclear. To date, there are only five case reports globally on MBC with concurrent prolactinoma. We hereby describe the first case of MBC with prolactinoma in China. We also explored the patient's genetic profile using whole exome sequencing. Our findings may help advance our understanding of the molecular pathogenesis of MBC. Further molecular analyses of such cases are warranted to improve auxiliary molecular diagnostic methods and targeted therapy for MBC.
