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 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 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.

ObjectiveTo observe the efficiency of hematopoietic stem cell transplantation to the treatment of hematological malignancies and explore prevention and treatment of the complications correlated with HSCT. Methods110 patients with hematological malignancies which were treated by HSCT were recruited. 61 patients were treated with autologous peripheral blood hematopoietic stem cell transplantation (auto-PBSCT), 49 patients were treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT).Among them,there were 28 patients were used by all HLA-identical sibling allo-PBSCT,20 patients were used by haploid allogeneic bone marrow and peripheral blood stem cell transplantation, one case of acute lymphoblastic leukemia in children were treated with cord blood stem cell transplantation.Results109(99.1％) patients acquired hemopoietic reconstruction. The median time of neutrophils≥0.5×109/L, and platelets≥20×109/L were 10 days and 12 days in auto-PBSCT,and were 12 days and 15 days in allo-PBSCT.The incidence of Ⅰ-Ⅲ degree of acute GVHD (aGVHD) in allogeneic transplantation was 28.6 ％(14/49),however,the incidence of chronic GVHD (cGVHD) was 32.6 ％(16/49).The median follow-up time was 36 (1～60) months.84 patients (76.4 ％) were disease-free.Among them,73.8 ％(45/61) were in auto-PBSCT group,(79.6 ％)39/49 were in allo-HSCT group.26 patients (23.6 ％) were died.There were 26.2 ％(16/61) who were in auto-PBSCT group died of disease relapse,3.3 ％(2/61) had disease relapse.There was no transplant-related deaths.18.4 ％(9/49) who were in allo-HSCT group died of disease relapse, 6.1％(3/49)had disease relapse, 2.0 ％(1/49)died of transplant-related deaths. ConclusionHematopoietic stem cell transplantation is a safe and effective way for the treatment of malignant hematopathy patients,also an important mean for treatment of blood diseases.

Purpose To investigate the corre1ation of the epiderma1 growth factor receptor( EGFR)gene mutation and amp1ification and protein expression with occurrence and deve1opment of non-sma11 ce11 1ung cancer( NSCLC),and to exp1ore the re1ationship be-tween the mutation and amp1ification of EGFR gene and other c1inica1 patho1ogica1 parameters. Methods qRT-PCR,FISH and immu-nohistochemistry were used to detect EGFR gene(exons 18,19,20 and 21)mutation,amp1ification and protein expression in paraf-fin-embedded tissues of NSCLC. Results EGFR gene(exons 18,19,20 and 21)mutation rate was 58. 18%(32/55)in NSCLC with qRT-PCR techno1ogy,in which the occurrence rate of exon 19 de1etions and exon 21 mutation of L858R was 87. 50%(28/32). EGFR gene mutation rate was significant1y different in gender,smoking history and patho1ogica1 type(P<0. 01),but no statistica1 sig-nificance in age,1ymph node metastasis and TNM staging(P>0. 05). EGFR gene amp1ification rate was 23. 64%(13/55)and its protein expression rate was 70. 91%(39/55). Both EGFR gene mutation and amp1ification was c1ose1y corre1ated(P<0. 05),but the two states of EGFR gene and its protein expression had no corre1ation(P>0. 05). Conclusion EGFR gene mutation with high pro-tein expression of NSCLC is common1y found in fema1e,no-smoking and adenocarinoma patients,who are main candidates of a tyrosine kinase inhibitor( TKI)screening. EGFR gene mutation and amp1ification is typica11y corre1ated,but their consequence is unknown, which needs to be further investigated. EGFR gene mutation and amp1ification is not consistent with protein expression,its under1ying machanism is to be determined.

Objective To improve the understanding of pulmonary mucormycosis by analyzing the clinical manifestations,imaging features,diagnosis,treatment and prognosis of this disease.Methods The clinical data of eight patients diagnosed as pulmonary mucormycosis by histopathologic examination were retrospectively analyzed.Results Eight patients included six males and two females with age from 36 days to 66 years.Underlying conditions covered diabetes (n =4),renal transplantation (n =3),premature (n =1) and long-term corticosteroid treatment in two cases.Imaging manifestations revealed multiple irregular lumps or nodules in three cases,multiple cavities with thick wall in three cases,diffuse lung infiltrate in one case and lung opacities in one case.The diagnoses of seven patients were confirmed by percutaneous needle lung biopsy and the remaining one was diagnosed with fiberoptic bronchoscopy biopsy.Surgery combined with amphotericin B liposome(60 mg/d for three weeks)was applied to one patient who was cured with no recurrence after a 22 month follow-up.Three cases were given amphotericin B liposome (a newborn with 7mg/d for 62 days,the other two 60 mg/d for 31 days and 70 mg/d for 71 days respectively).All had achieved marked response with follow up from 8 to 29 months,but one patient relapsed and died of recurrent lung mucormycosis.The other three patients were treated with itraconazole 400-200 mg/d from 21 days to 1 year with duration of follow up from 1 month to 20 months.One patient was not evaluable due to missing.Two patients relapsed and one died.Conclusion Pulmonary mucormycosis is difficult to diagnose and treat with a high mortality.Percutaneous tranthoracic lung biopsy is a useful diagnostic method.Amphotericin B liposome or itraconazole may be active against mucus.Early control of causes is essential to improve the prognosis and reduce the recurrence in patients with pulmonary mucormycosis.

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
