Objective To study the clinicopathological characteristics of complicated Kaposi's sarcoma after renal transplantation.Methods Five cases of complicated Kaposi's sarcoma after kidney transplantation were studied by histopathological immunohistochemical and ultrastructural observations.Results Of the 5 Kaposi's sarcoma patients,2 had multiple amaranthine dermal plaques starting on the legs,one had lymph node hypertrophy all over the body,and others had inguinal lymph node and adenoid hypertrophy. Histopathologically,these angiomatous lesions had characteristic areas of spindle cells within which erythrocytes were enmeshed.Admixed in these lesions were hyaline bodies and hemosider-laden,phagocytic cells.Immunohistochemical and ultrastructural studies revealed that this tumor was derived from vasofomative mesenchyme with multipotential capabilities.It was found that the epithelia and spindle cells were positive for Vimentin,CD-31,CD-34 and Ⅷ-RAg.Conclusion Complicated Kaposi's sarcoma after kidney transplantation can be diagnosed by combination of clinical manifestations and histopathological examinations with immunohistochemical and ultrastructural observations.

ObjectiveTo study the clinicopathologic features of post-transplant lymphoproliferative disorders (PTLD).Methods Three cases of PTLD in renal transplant recipients were studied.The clinical data,diagnosis and differential diagnosis,and relevant literatures were also reviewed.Results All the 3 cases studied had received cyclosporine A or Tac after transplantation.The duration between organ transplantation and diagnosis of PTLD was 10 years,4 years and 2 months respectively.Two cases were suffered from monomorphic PTLD and 1 from plasmacytic hyperplasialike PTLD in morphology.Two cases of monomorphic PTLD died within one year after diagnosis.Conclusion PTLD is a lymphoproliferative disease with distinctive morphologic and clinical characteristics.The main treatments included the dosage reduction of immunosuppressive agents,radiotherapy and chemotherapy.The prognosis of monomorphic PTLD was poor.

Objective To investigate the correlation between clinical presentations and the findings of video fluoroscopic swallowing study (VFSS)in patients with post-stroke dysphagia. Methods A total of 56 consecutive patients with post-stroke dysphagia admitted to Wenzhou Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University from June 2012 to May 2014 were enrolled. Four different kinds of food were selectively used to complete clinical assessment of swallowing function and VFSS respectively. The SPSS 20. 0 statistical software was used to perform univariate and multivariate Logistic regression analyses for all observed indexes of the 2 methods. Results there were significant correlations in the point correspondence relation among the clinical manifestations and VFSS in food residue in the mouth and abnormal closure of lips in the oral phase (95%CI 1. 430-101. 468;P=0. 022);poor soft palate elevation and food residue in the mouth (95%CI 1. 476-102. 033;P=0. 020);graded swallowing and piecemeal deglutition with delayed oral transit (95% CI 2. 616 -182. 897;P = 0. 004);tongue movement disorders,poor soft palate elevation and tongue dyskinesia with poor bolus formation (95%CI 1. 468-50. 795,1. 220-13. 825;P=0. 017,0. 023);food leak from the corner of mouth,dysphagia,bolus falling to the epiglottis from the base of tongue or trachea (95%CI 1. 146-125. 459,1. 657-174. 400;P=0.038,0. 017). The weakened pharyngeal reflex with weak laryngeal elevation in the pharyngeal phase (95%CI 1. 150-92. 815;P =0. 037);dysphagia and delayed swallowing with prolonged triggering of swallowing reflex (95%CI 2. 123-37. 770,1. 233-114. 176;P=0. 003,0. 032);graded swallowing,hard swallowing, choking sensation,and poor laryngeal elevation with prolonged pharyngeal transit (95%CI 1. 619-223. 316,1. 061-31. 445,2. 834 -132. 707;P =0. 019,0. 042,and 0. 003);dysphagia and the opening of cricopharyngeal muscle insufficiency (95%CI 1. 037 -24. 115;P =0. 045);weak laryngeal elevation,foreign body sensation in the throat,and choking after swallowing with food retention or residual in vallecula or pyriform sinus (95%CI 1. 046 -13. 685,1. 116 -87. 741;P =0. 043, 0.040);and coughing during swallowing and eating choking or aspiration (95%CI 0. 010-0. 921,0. 037-0. 826;P=0. 042,0. 028). Conclusion Some clinical manifestations are closely correlated with the swallowing dysfunction revealed by VFSS. With the help of this law,it may more simply and safely determine the degree and type of dysphagia in patients,and provide guidance for patients with dysphagia after stroke who can not accept VFSS in the rehabilitation treatment.

Aim To explore the potential mechanism of ulinastatin’s antioxidant effect by examining the Nrf2 /HO-1 pathway.Methods OVA-induced asthma of mice was cured by intraperitoneal injection of ulinas-tatin (1 00 kU·kg -1 ·d -1 ).Control mice were given the same volume of PBS (pH 7.4).To investigate the effect of ulinastatin on airway hyperresponsiveness, levels of interleukin IL-4,IFN-γand OVA specific IgE in bronchoalveolar lavage fluid (BALF)were measured using enzyme-linked immunosorbent assays (ELISAs). The content of ROS from BALF of mice was tested in double hydrogen rhodamine (DHR)-1 23 method.The level of protein carbonyl and MDA from lung tissue of mice was detected with Protein carbonyl content assay kit and MDA kit.And antioxidative enzyme in mice BALF was tested by antioxidant enzyme kit.The levels of HO-1 in lung tissue from mice were detected by Western blot and Real-time PCR.Nuclear transfer and binding activity of Nrf2 were tested respectively by Western blot,IF and EMSA.Results Ulinastatin could alleviate the airway hyperresponsiveness,dis-tinctly reduce the content of IL-4,OVA specific IgE, ROS,protein carbonyl and MDA,but upraise the ex-pression of IFN-γand antioxidative enzyme such as SOD,GSH and TAOC. Moreover, the antioxidant effect of ulinastatin could be reversed by Znpp,which was the inhibitor of HO-1 .Ulinastatin could obviously induce the expression of HO-1 in protein level in a dose-and time-dependent manner.Ulinastatin could also induce the nuclear transfer of Nrf2 and increase the binding activity of Nrf2 as well as the expression of HO-1 in gene level;Conclusion Ulinastatin could induce the activation of Nrf2 /HO-1 pathway,which may contribute to the protective effects of ulinastatin a-gainst OVA-induced oxidative stress.

Objective:To study the inhibitory and apoptosisinducing effect of vitamin E succinate(VES) on androgen-independent prostate cancer cell line PC-3 in vitro.Methods: VES was dissolved with ethanol to obtain VES solution.PC-3 cells of logarithmic growth phase were treated with various concentrations of VES solution(25,50,75,100,and 125mg/L);cells in control group were treated with 1.25% ethanol.MTT method was used to measure the viability and inhibitory rate of cells in each group 24h,48h and 72h after VES treatment;flow cytometry was employed to determine the apoptosis rate of the PC-3 cells.Results: The viability of cells in the experimental groups was significantly lower than that in the control group(P

Objective To investigate the clinical features,radiology,diagnosis and treatment of postkidney-transplant pulmonary mucormycosis.Method Three cases of post-kidney-transplant pulmonary mucormycosis were successfully diagnosed by histopathologic examinations.The clinical features of the cases were analyzed.The patients consisted of 2 males and 1 female,aged 39 to 54 yearn All patients were subjected to renal transplantation due to uremia,one was complicated with with diabetes,and pulmonary mucormycosis occurred 6 months,2 years and 6 years after kidney transplant respectively.Fever,cough,bloody sputum and chest pain were the main clinical manifestations.Multiple irregular massive or diffuse infiltrates in the lungs were the early CT findings.In a shoot time,multiple thick-walled cavities occurred in the pulmonary lesions.Pleural effusion was found in one patient.The lung specimens of patients were obtained by CT-guided percutaneous biopsy.Result The first patiem was cured after one year therapy by hraconazole,but recurred after 8 months.The second patient had a marked effect after a 21-day therapy by Itraconazole,but died of disseminated mucor for excessive immunosuppressant against the renal transplantation rejection.The third patient also had a marked effect,and was still in follow up.Condusion The post-kidney-transplant pulmonary mucormycosis is difficult in diagnosis and treatment.CT-guided percutaneous biopsy is one of effective ways for diagnosis.Itraconazole appears to be effective in treatment of pulmonary mucormycosis.Early diagnosis and an appropriate immune ftmction are the keys to improve prognosis and reduce recurrence

ObjectiveTo observe the expression of nephrin in hepatitis B virus-associated membranous nephropathy (HBV-MN),and investigate the impairment and significance of podocyte in HBV-MN.MethodsThe protein expression of nephrin in renal biopsy specimens in 35 patients,who were diagnosed as HBV-MN by renal biopsy,was determined by immunohistochemistry and tested by semiquantitative method.The relationship between the expression of nephrin and clinicopathological data was analyzed.Results Among the 35 cases with HBV-MN,6 were in MN phase Ⅰ,20 in MN phase Ⅱ and 9 in MN phase Ⅲ.A strong intensity expression of nephrin in normal glomerulus was found along capillary loop of glomerulus,while its expression in HBV-MN patients decreased obviously.There was no significantly difference in the expression of nephrin among the different stages of HBV-MN ( P ＞ 0.05 ).The expression of nephrin in different clinical types was significantly different ( P ＜ 0.05 ).The expression of nephrin in patients with nephrotic syndrome was significantly lower than that in patients without nephrotic syndrome (P ＜0.01 ).The expression of nephrin in different grades of 24-hour urinary protein excretion quantity was significantly different( P ＜ 0.05 ).There was negative correlation between the expression of nephrin and 24-hour urinary protein excretion quantity(r = -0.378,P ＜ 0.05).In the patients with HBV-MN phase Ⅱ,the expression of nephrin in patients with nephrotic syndrome was also significantly lower than that in patients without nephrotic syndrome( P ＜ 0.01 ).Conclusions The damage of podocytes emerge in the early stage of HBV-MN and the expression of nephrin in HBV-MN patients,especially in patients with nephrotic syndrome,are significantly down regulated.The descended expression of nephrin in HBV-MN patients may promote the production of proteinuria.

ObjectiveTo study the amplification and expression of HER-2 gene and protein in breast cancer and to investigate the relationship between HER-2 gene and Ki-67 、P53 、ER、PR、lymph node metastasisandTNMstaging.MethodsFluorescenceinsituhybridization(FISH) and immunohistochemistry(IHC) method were used to detect the amplification and expression of HER-2 and the expression of Ki-67、P53、ER、PR in 150 cases of breast cancer. Results49 out of 150 cases were amplificated,positive rate of HER-2 gene was 32.68％.In the 32 patients whose expression of HER-2 protein was ( + + + ),HER-2 gene was expressed in 28 cases.In The 46 patients whose expression of HER-2 protein was ( + + ),HER-2 was expressed in 16 cases.In the 26 patients whose expression of HER-2 protein was ( + ),HER-2 was expressed in 3 cases.In the 47 cases that the expression of HER-2 protein was negative,there were 45 cases that the expression HER-2 gene was negative.The expression of HER-2 was correlated with ER,PR expression and TNM staging,but not significantly related with age,Ki-67,P53 and lymph node metastasis.ConclusionsFISH and IHC correlate well with each other in the determination of HER-2 gene amplication and protein expression in cases of invasive breast cancer.

Objective To investigate the diagnosis and treatment of hepatic metastasis from gastrointestinal stromal turnor(GIST).Methods The clinical data of 16 patients with GIST who had been admitted to our hospitalfrom December 1993 to May 2007 were retrospectively analyzed.Results Of all patients,14 underwent radical resection and 2 underwent palliative operation.Two patients with palliative operation and 3 with radical resection were administered with imatinib postoperatively. All patients were followed up for 3-161 months,and GIST metastasis and invasion was observed in 8 of the 14 patients who received radical resection.Of the 7 patients with hepatic metastasis.3 were treated with hepatic artery chemoembolization,1 was administered with imatinib,2 received reoperation and 1 did not receive any treatment. Reoperation was carried out on 1 patient who had abdominal wall metastasis.The 1-and 3-year survival rates of the 16 patients were 92%and 74%,respectively.Conclusions The recurrence rate of GIST after hepatectomy is high.Complete surgical resection is the best curative treatment for hepatic metastasis from GIST and GIST recurrence.The combination of surgical resection and imatinib administration may help to improve the prognosis of patients with hepatic metastasis from GIST.
