ObjectiveTo discuss the diagnosis method and management of Gallbladder polypoeid lesions (GPL).MethodA ten-year (2002-2011) retrospective reviews of all patients result underwent in ultrosenography (US) was conducted.ResultsTotal 591 peatients with GPL detected on US were identified,349 patients (59.1％) were women,the age ranges 20 to 93 years.395 patients had abdominal symtoms,of which 39.9％ patients had a single polyp and 9.8％ had gallstones.The specifisity of the diagnosis of GPL in US was 92.5 ％.Laparascopic cholecystectomy (LC) is the treatment of 136 chosen cases.In cases suspicious of malignancy,it is advisable to do cholecystectomy.ConclusionsMost small GPL are benign and remain static for years.Age more than 50 years old and size of polyp more than 10 mm are the two main important risk factors predicting malignancy in GPL.Other risk factors include concurrent gallstones,solitary polyp,and symptomatic polyp.LC is the treatment of unless since the suspicion of malignancy is high.

Objective To investigate the clinical features,surgical treatment and prognosis of female breast cancer patients under 35 years.MethodsThe clinical data of 140 cases of female breast cancer patients in the young group ( ≤ 35 years) and 326 cases of female breast cancer patients in the control group ( 45 - 59years) undergoing surgical treatment from 2002 to 2009 in our hospital were analyzed retrospectively.All the data were analyzed with the statistical software of SPSS13.0.ResultsThe difference between the 2 groups had no statistical significance in tumor size or pathologic types( P ＞0.05).The axillary lymph node metastasis rate was obviously higher in the young group than in the control group ( P ＜ 0.05 ). Modified radical mastectomy and breast-conserving surgery were mainly performed.The proportion of patients in stage Ⅲ and Ⅳ in the young group was higher than that in the control group.The positive rate of ER and PR was lower while the positive rate of HER-2 was higher in the young group than those in the control group( P ＜ 0.05 ).ConclusionsBreast cancer in young women has the features of high clinical stage,high lymph node metastasis rate,low positive rate of ER and PR,high positive rate of HER-2,high recurrence rate and poor prognosis.The treatment principle of the diseaseis comprehensive therapies mainly based on surgical treatment.

A red pigmant, procligiosin, have been isolated from the metabolite of germ pseudomonas sp. collected from the Dayawan Bay. Its structure was established on the basis of the spectral method.

Objective To discuss the standard diagnosis and treatment for thyroid nodule.Methods 2 581 patients with thyroid nodule from 2005 to 2009 were studied.Common methods of examination and treatment were analyzed to avoid over-examination and over-treatment.Results 90%of the patients underwent ultrasound examination with a 92.9%sensitivity and 44.3%specificity when there were two or more risk characters.All patients underwent certain kinds of surgery according to their clinical conditions.The recurrence rate was 4%two and half years after lateral thyroid adenectomy or thyroid surgery without excision of thyroid isthmus.Conclusions There are many approaches to thyroid nodule examination and treatment,in which ultrasound is recommended for preoperative examination because of its higher sensitivity,specificity and lower cost,and surgery is still the most useful and effective treatment.Choosing the proper method for thyroid nodule diagnosis and treatment is the key point to avoid over-examination and over-treatment.

Objective Within human hepatoma cell lines,we aimed to investigate the effects of the down-regulation by RNAi on different fragments of osteopontin (OPN) in order to discover more effective and accurate sites for OPN.Methods Specific small interfering RNA of OPN (OPNi-1) were synthesized and transfected into human hepatoma cell line (HEP-G2).Fluorescent quantitative PCR and immunohistochemical methods were used to test*the OPN expression levels of mRNA and protein before and after RNAi.Results After transfection,the △CT value of the A fragment was greater than B and C fragments of OPN mRNA in HEP-G2.Before RNAi was added to HEP-G2 cells,the three fragments A,B,C had OPN mRNA CT values of 8.31±1.58,8.78±1.49,8.25±1.51 respectively.Once the RNAi were added,the CT values were measured 48h after for the fragments A,B,and C which were 12.14±1.43,10.22±1.97,10.48±1.88 (P＜0.05) respectively.The immunohis tochemical values of A,B,C were down from 6.44±1.67,5.43±2.05,5.45±2.52 to 2.84±1.52,4.43± 1.65,3.95± 1.43 respectively after interference.Conclusions RNAi can inhibit the expression of OPN gene selectively.siRNA targets different segments of OPN,which may have more effects on invasion and metastasis of liver cancer for a more important significance in science and health economics.

Objective To investigate the expression of livin of kidney tissues in rats with acute kidney injury (AKI) induced by endotoxin ,and the role of livin in the cell apoptosis of AKI .Methods The rat models with AKI were induced by endotoxin .The de-gree of kidney injury was observed by hematoxylin and eosin stain ,measuring the levels of the serum creatinine and urea nitrogen . The expression of livin and caspase-3 in kidney tissue at different time points was analyzed by immunohistochemistry assay ,and the relationship between the expression of livin and caspase-3 and kidney injury was analyzed .Results Compared to the control group , the rats injected endotoxin had the performance of AKI ,with obviously pathomorphological damage in the kidney tissues ,signifi-cantly increasing in the serum creatinine and urea nitrogen (P<0 .01) .The livin and caspase-3 of kidney tissues in rats with AKI caused by endotoxin were positive expression (P<0 .01) .With the lapse of time ,the trend of increasing of caspase-3 showed gradu-ally slow after the highest expression of livin .Conclusion The livin involved in the pathogenesis of endotoxin-induced AKI ,it might relieve the kidney injury and protect renal function by inhibiting casepase-3 important apoptotic effector protein .

Recombinant human interferon α2b(rhIFNα2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNα2b is complex.In this study,an anti-rhIFNα2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNα2b.RhIFNα2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNα2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNα2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNα2b detection assay had a limit of detection of 1 μg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other com-mercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.
