Objective To investigate the indication, methods and therapeutic effects of breast-conserving surgery in mammary cancer of early stage. Methods A retrospective study on 28 cases of Ⅰ and Ⅱ stage of breast-conserving surgery was underwent. Results Breast-conserving surgery does not destroy the appearance symmetry of breast, and maintains a low baldness rate. The recurrence rate in 5 years after surgery is 5.3%, and the 5 years' survival rate is 100%. Conclusion Breast-conserving surgery combined with the hinese herbal medicine therapy is an effective and safe way to treat mammary cancer in a early stage.

Objective To evaluate brush cytology under endoscopic retrograde cholangiopancreatography (ERCP) for malignant biliary strictures, and to analyze the factors influencing the diagnosis yield.Methods Brush cytology was applied in 144 patients with suspected malignant biliary strictures at ERCP.Brushing in bile duct was performed for 10 times from 2004 to 2006, while at least 20 times of brushing and repeated manipulation were performed at biliary strictures from 2007 to 2009. Cytological samples were processed immediately after brushing and analyzed by the same pathologist. Efficacy of brush diagnosis was evaluated based on reference to histopathology after surgery and/or clinical diagnostic criteria. Results Malignant stricture was finally diagnosed in 96 patients, and benign diseases in other 48. Brush cytology was positive in 78 of 96 patients with malignant stricture ( sensitivity 81.3% ), and negative in all patients without malignancy ( specificity 100. 0% ). Overall accuracy of diagnosis was 87.5%. Positive rate of malignancy by brush between 2007 and 2009 was 87.7% (50/57), while that between 2004 and 2006 was 71.8%, which were significantly different ( P ＜ 0. 05 ). The positive rate was not correlated with stricture location or tumor type. No major complications occurred, except for 4 moderate acute pancreatitis, 3 cholangiolitis and 2 biliary bleeding. Conclusion Brush cytology is of high sensitivity and specificity for malignant biliary stricture.Repeated brushing and manipulation can facilitate diagnosis yield.

Objective To investigate the effect of mitogen-activated protein kinase(MAPK)pathway on the transcriptional expression of mdr1 gene induced by doxorubicin ( DOX)and study the transcription regulation of mdr1 gene.Methods K562 cells were treated with DOX(0.01 μg/ml)with the initial concentration of 0.01 μg/ml for 24 hours,then change the culture media without DOX.K562 cells were cultured until the its status wag recovered.Subsequently the cells were treated with DOX(0.02μg/ml)for 24 hours again.The concentration of DOX was increaged until 0.05 μg/ml by following the protocol above.K562 cells were collected at the concentration of 0.01 μg/ml,0.03μg/ml and 0.05μS/ml DOX.Expression of mdr1 gene were examined by reverse transcription-polymerase chain reaction(RT-PCR).Pglycoprotein(P-gP)wag detected by flow cytometry.Western blot wag performed to detect ERK and P-ERk.K562 cells were pretreated with MAPK inhibitor PD98059 for 1 hour.and then DOX was added.RT-PCR and FCM were used to detect the expression of mdr1 mRNA and P-gp.Results When K562 cells were exposured to DOX.the phosphorylation of ERK wag increaged.the mdr1 gene wag highly expressed as well as its corresponding protein P-gp.When the concentration of DOX was 0.05μg/ml,the expression of mdr1 gene and P-gp were increased over 5 fold.When K562 cells were pretreated with MAPK inhibitor PD98059,the expression of mdr1 gene induced by DOX(the concentration was 0.03 μg/ml and 0.05 μg/m1)was effectively inhibited by(74.1±0.11)%and(70.2±0.14)%respectively.Conclusions DOX could induce the expression of mdr1 gene in K562 cells accompanied by the activation of MAPK/ERK pathway.The block of activation of ERK could inhibit the induced expression of mdr1 gene.

Aim To investigate the antitumor and antiangiogenic effects of combined low-dose cyclophosphamide(CTX)and recombined VEGF protein vaccine.Methods In this experiment,H22 hepatocellular carcinoma model was established in BALB/c mice.Mice were randomly divided into four groups: control group,CTX group(CTX),VEGF protein vaccine group(V2)and CTX plus V2 group(CTX+V2).The anti-tumor efficacy and antiangiogenic effect were investigated using a subcutaneous tumor model and an intradermal tumor model.Western blot and ELISAwere further adopted to detect the specific anti-VEGF antibody.Results CTX+V2 group displayed a lower tumor volume and tumor weight than either the single therapy group in the subcutaneous tumor model(P<005 vs V2,P<001 vs CTX).Meanwhile,CTX+V2 was more effective for antagonizing tumor-associated angiogenesis compared with either the single therapy(P<005 vs V2,P<001 vs CTX).After CTX+V2 immunization,high titer of anti-VEGF antibody was detected by ELISA and verified by Western blot.Conclusion The therapy of CTX combined with V2 has significant synergistic effect against H22 hepatocellular carcinoma.

Objective To evaluate the peri-operative and survival outcomes of hepatectomy combined with splenectomy in patients with hepatocellular carcinoma with Barcelona Clinic Liver Cancer Stage A and portal hypertension.Methods We retrospectively analyzed the data on patients with hepatocellular carcinoma with Barcelona Clinic Liver Cancer Stage A and portal hypertension who underwent surgery at the Shengli Oilfield Central Hospital between July 2008 and June 2015.According to the operative method,the patients were classified as the experimental group (hepatectomy combined with splenectomy) and the control group (hepatectomy).We compared and analyzed the clinical data between these two groups,which included the operation time,blood loss,duration of hepatic portal occlusion,width of surgical resection margin,liver function,PLT,HBV reactivation,time to remove drainage tube,complications,upper gastrointestinal hemorrhage rate and survival outcomes.Results (1) The operation time,blood loss,PLT at 1 week and 1 month after surgery in the experimental group were all significantly higher than the control group [(161.4 ± 38.3) min vs.(119.2±36.4) min,(268.7±72.1) vs.(201.3±61.3) ml,(189.2±51.3) ×109/L vs.(81.9±32.2) ×109/L,(327.4±69.1) ×109/L vs.(84.5±28.5) × 109/L (all P＜0.05),respectively].The time to remove drainage tube,duration of hepatic portal occlusion,width of resection surgical margin,TBil,complications and upper gastrointestinal hemorrhage rates of the two groups were not significantly different (all P ＞ 0.05).The HBV reactivation rate,ALT and AST in the experimental group were significantly lower than the control group [3.9％ (2/51) vs.18.2％ (12/66),(45.7 ± 11.4) U/L vs.(58.3±14.7) U/L,(48.1±12.4) U/Lvs.(61.3±15.1) U/L (allP＜0.05),respectively].(2) The 1,3 and 5-year recurrence free survival rates were not significantly different between the experimental and control groups [84.3 ％,34.1％,27.3 ％ vs.78.8 ％,42.1％,9.7 ％ (all P ＞ 0.05),respectively].The 1,3 and 5-year overall survival rates in the experimental Group were significantly higher than the control group [94.1％,66.3 ％,33.5 ％ vs.90.9％,46.7％,16.1％ (all P ＜ 0.05),respectively].Conclusion Combined liver and spleen resection was a safe and efficacious modality to treat patients with BCLC A hepatocellular carcinoma,which reduced the incidence of HBV reactivation and improved the overall survival.

To report a case of imported furuncular cutaneous myiasis,and to analyze the sequence of the mitochondrial cytochrome C oxidase subunit Ⅰ (CO Ⅰ) gene of the pathogenic Cordylobia anthropophaga.A 33-year-old female patient had a travel history to Ghana and Cameroon in Africa 1 month prior to the presentation.No anti-mosquito measures were taken during her stay,and she hung up the laundries outside to dry for several times.Skin examination showed furuncular protuberances with diameters of 1-2 cm on the inner side of the left upper arm as well as on the outer side of the left chest,which were bright red and hard on palpation with irregular borders and a small hole on their central surface.Morphological identification revealed that the larva squeezed from the lesion was suspected as myiasis.After PCR amplification of the CO Ⅰ gene of the larva,an about 650-bp PCR product was acquired.Sequencing and BLAST analysis showed that this product was most closely related to the CO Ⅰ gene (GenBank accession number:FR719158.1) of Cordylobia anthropophaga isolated in Cameroon in 2010 with the sequence similarity being 99.84％,and they were grouped together on the phylogenetic tree.According to the clinical features and travel history of the patient and the sequencing results of the pathogenic Cordylobia anthropophaga,this case was confirmed as imported furuncular cutaneous myiasis caused by Cordylobia anthropophaga.
