Objective To explore and evaluate the effect of 32P and pinyangmycin injected in combination for the treatment of maxillofacial hemangioma. Methods The patients were randomly divided into three groups. The first group of patients was treated with 32P; 100 patients were enrolled in this group, of which 37 were male and 63 female. 32P dosage between 0.37 and 0. 74 MBq per cm3 was prepared together with 0.5 ml of 2 %lidocaine, and appropriate normal saline, and then the mixture was injected into hemangioma every two weeks. The second group was given pinyangmycin, and the third group received both 32P and pinyangmycin. The second group included 30 male and 60 female, and the third group 64 male and 136 female. The dose and frequency were given as the same to the first group. Results 88.5 % of patients were cured using both 32P and pinyangmycin, and the cure rate was 77.0 % and 71.7 % with either 32P or pinyangmycin. Conclusion These results prove that 32P and pinyangmycin injected in combination for the treatment of maxillofacial hemangioma is more effective than either 32P or pinyangmycin alone, and furthermore, the method is easy, safe and has less complications.

Objective Invasive candidiasis is associated with a significant mortality clinically.The purpose of this study was to observe the T cells immune response to fructose bisphosphate aldolase (Fba), an immunodominant antigen of Candida albicans, and determine whether the antigen has the possibility of priming cellular immune protection in invasive candiasis.Methods Using ELISPOT assay, we determined the frequencies of positive spot-forming cells (SFCs) of Fba antigen-specific T cells secreting IFN-γ, IL-4 and IL-17A in the peripheral blood mononuclear cells (PBMCs) of 26 healthy individuals.Results After Fba stimulation, the frequencies of positive SFCs of IFN-γ, IL-4 and IL-17A in the 26 healthy subjects were 23 (9.75, 42.50), 0 (0, 0.25) and 1.5 (0.75, 8.25), respectively, with statistically significant differences among the three (P<0.01).The response rates of IFN-γ (100% [26/26]) and IL-17A (76.92% [20/26]) were significantly higher than that of IL-4 (15.38% [4/26]) (P<0.01).Fba-induced strong response (SCFs ≥20) for IFN-γ was observed in 57.69% (15/26) of the healthy individuals, that for IL-17A in only 1, while that for IL-4 in none.Responses of both Th1 and Th17 cells to Fba were found in 65.38% (17/26) of the subjects, that of Th1 cells in 19.23% (5/26), but that of Th2 cells in none.Conclusion Fba of Candida albicans can induce immunodominant responses of Th1 and Th17 cells and is a potential vaccine against invasive candiasis.

Objective: To evaluate the efficacy of 3LL/GM-CSF tumor vaccine combined with pacilitaxel chemotherapy in treatment of mice bearing transplanted Lewis lung carcinoma. Methods: The tumor vaccine 3LL/GM-CSF was prepared by infecting Lewis lung carcinoma cell line 3LL with adenovirus encoding GM-GSF. Mice model of Lewis lung carcinoma was established by subcutaneous injection of 2?104 3LL cells into C57BL/6(H-2b)mice. The sensitivity of Lewis lung carcinoma cell line-3LL to the treatment of pacilitaxel was detected in vivo and in vitro. The mice tumor model was first treated with pacilitaxel chemotherapy and then with 3LL/GM-CSF, or first with 3LL/GM-CSF and then with pacilitaxel. Tumor growth and the long-term survival of mice were observed after treatment. The immune memory and cytotoxicity against target cells were studied in the mice. Results: Pacilitaxel at 100 nmol/L killed 32.10% 3LL cells after 24 hour in vitro; but pacilitaxel at 5-25 mg/kg only had a poor effect on growth of 3LL cells in vivo. The tumors rebated in 70% of mice treated with pacilitaxel chemotherapy and 3LL/GM-CSF vaccination successively, and the survival of these mice was obviously longer than that of pure pacilitaxel chemotherapy group (70.0 days vs 27.5 days). The killing rate of 3LL/GM-CSF after pacilitaxel chemotherapy was 41.35% on day 3. Meanwhile, the survival mice could resist the re-attack of 3LL cells (2?104). We also noticed that first treatment with 3LL/GM-CSF and then pacilitaxel chemotherapy had no effect on tumors. Conclusion: Application of tumor vaccine shortly after pacilitaxel chemotherapy can induce specific immune responses and prolong the survival of experimental mice, which provide a basis for future clinical practice.

Objective To investigate the effect of continuous veno-venous hemofiltration (CVVH) on pulmonary vascular permeability in the early stage of septic shock.Methods Fifty-one patients of septic shock admitted in intensive care unit of the First Affiliated Hopsital of Medical College,Zhejiang University between June 2010 and December 2011 were randomized into two groups by simple random method.Routine treatment was carried out to patients in group A,and routine treatment plus CVVH to patients in group B in the first 72 hours.Repeated respiratory mechanic hemodynamic measurements were done at baseline (Tb) before treatment,at 48 hours (T48) and 72 hours (T72) after the treatment.Pulmonary compliance (Cst),platform pressure (Pplat),oxygenation index (PaO2/FiO2),extravascular lung water index (EVLWI) and E-selectin determined at each time point were recorded in two groups.Results (1) Pplat were decreased significantly after treatment in two groups,and the Pplat in group B were all lower than those in group A at T48 and T72 (t =2.215,P ＜ 0.05 ; t =4.266,P ＜ 0.01).Cst were elevated after treatment in two groups,and Cst in group B were all higher than those in group A at T48 and T72 (t =2.516,P ＜0.05 ; t =3.052,P ＜ 0.01).(2) Compared to before treatment,PaO2/FiO2 increased significantly after treatment in two groups,and PaO2/FiO2 in group B were all higher than those in group A at T48 and T72 (t =2.732,P ＜0.01 ; t =3.511,P ＜0.01).(3) EVLWI were decreased significantly after treatment in two groups,and the EVLWI in group B were all lower than those in group A at T48 and T72 (t =2.597,P ＜0.05; t =2.125,P ＜ 0.05).ITBVI,CI,SVRI and MAP did not change over time in two groups compared with those at Tb (all P ＞ 0.05).(4) E-selectin were decreased significantly after treatment in two groups,and the E-selectin in group B were all lower than those in group A at T48 and T72 (t =2.154,P ＜0.05 ; t =3.581,P ＜ 0.01).Conclusion CVVH in early stage of septic shock can improve pulmonary vascular permeability and oxygenation,increase Cst,and decline EVLWI,with neither increased hemodynamics.

Objective To investigate the clinical and pathological features,diagnosis,differential diagnosis,treatment and prognosis of secondary Hodgkin's lymphoma of ureter.Methods We retrospectively analyzed one case with retroperitoneal Hodgkin's lymphoma involving right ureter.A 63-year-old male patient was referred to our hospital on January 22th,2013 with right hydronephrosis for 15 days,detected by abdominal color Doppler ultrasound due to constipation and difficult defecation without any urinary symptoms.Urinary CT scan revealed that there were dilation and hydrops of right pelvic and ureter in the middle and upper segment.The distal portion of ureteral wall was thick with a stenosis lumen.There was multiple larged lymph nodes surrounding the abdominal aorta.So,it was clinically diagnosed as right ureteral carcinoma with lymphadenopathy and right hydronephrosis.The patient was then performed ureteroscopic inspection under general anesthesia.There was too narrow to go through smoothly the proximal ureter when the ureteroscope ascended 15 cm.Then,the exploratory surgery of right ureter was subsequently undergone.During operation,periureteral nodular mass and thickened wall were seen in the distal segment of ureter.Then the ureter lesion was partially excised with 1 cm and fast frozen pathology was undergone during operation.The result suggested chronic inflammation of ureteral.A 6Fr double J stent was left in the ureter.Then,the ureter was closed by 3-0 monocryl suture.Results The final pathological diagnosis was retroperitoneal Hodgkin's lymphoma with the lymph node involving the right ureter.After 40 days,the patient manifested high fever,night sweat,general lymphoadenomegalies.So,the clinical stage was classified as stage Ⅱ EB and poor prognosis group.Then,the patient received regular chemotherapy according to the ABVD (pirarubicin 20 mg/m2,bleomycin 10 mg/m2,vinblastine 1.4 mg/m2,dacarbazine 375 mg/m2) regimen over 8 cycles.Finally the symptomatology and diagnostic reassessment (hemato-chemical examinations and PET/CT) showed a clinical complete recovery after the follow-up period of 3 months.The follow-up plan is ongoing.Conclusions Because secondary Hodgkin's lymphoma of ureter is rare with concealed onset feature,lacking of characteristic clinical manifestations,it is relatively difficult to achieve the diagnosis and differential diagnosis.Therefore,pathology and immunohistochemistry should be assigned to confirm the diagnosis.It is stressed that physicians should be aware of the possibility of malignant lymphoma when unexplained hydronephrosis and thickness of the ureteral wall are found clinically.Generally it has a good prognosis and combination therapy for the treatment is given priority to with chemotherapy.
