Uterine papillary serous carcinoma is a special pathological type of endometrial cancer. It is similar to ovarian papillary serous carcinoma in histology and can have distant metastasis when it is still confined to the endometrium. As it is very aggressive and has a rather poor prognosis,complete surgical staging is necessary in the treatment,assisted by radiotherapy and chemotherapy. In this review,the author discussed the recent research advances in uterine papillary serous carcinoma.

Objectives To investigate the expression features and roles of the costimulatory molecules and T lymphocyte subsets from patients with chronic nephritis.Methods The expression of the costimulatory molecules CD 28 and CD 137 on PBMC (peripheral blood mononuclear cells) and T lymphocyte subsets from 52 patients with chronic nephritis were studied by immunophenotyping and flow cytometry analysis.Results The T lymphocyte subsets from patients with chronic nephritis showed an obvious imbalance with reversing CD 4/CD 8 ratio,decreasing CD + 4T cells and increasing CD + 8T cells.The expression of the costimulatory molecule CD 28 on T cells was significantly lower compared with normal controls (P

Objective To analyze the clinico-pathological characteristics, prognostic factors and the rational therapy for the uterine papillary serous carcinoma(UPSC). Methods Thirty-three cases of UPSC were treated in our hospital between January 1996 and December 2005. The clinico-pathologic characteristics, treatment and prognosis were retrospectively analyzed. Results The three-year overall survival for patients with stage Ⅰ, Ⅲ and Ⅳ was 77.4%,53.3% and 12.1%, respectively. Patients with late stages and deep myometrial invasion were associated with a worse prognosis by univariate analysis(P

Objective To evaluate the diagnostic value of 18F-FDG PET-CT in looking for tumor primary lesion with multiple bone metastasis.Methods 84 patients with suspected bone metastases were detected by routine imaging (X -ray,CT,MRI)in our hospital from May 2012 to September 2014 were selected,18F -FDG PET/CT were used to find the primary lesion.The final diagnosis were confirmed by tissue pathology or by clinical imaging follow -up.The diagnostic sensitivity,specificity and accuracy on tumor bone metastasis of 18F -FDG PET/CT were recorded.Results In 84 patients,primary tumor was found in 49 cases,of which 46 cases (54.8%)confirmed pri-mary tumor by operation or pathology,the other 3 cases were false positive;35 patients were diagnosed as non meta-static bone tumor by PET/CT,in which 34 cases were finally confirmed as non metastatic bone tumor by pathology and follow -up;accuracy,sensitivity,specificity of 18F -FDG PET/CT were 54.8%(46 /84),93.9% (46 /49)and 95.2%(80 /84);18 cases of lung cancer,9 cases of prostate cancer,7 cases of breast cancer,5 cases of lymphoma, 4 cases of renal cell carcinoma,2 cases of liver cancer,1 cases of Uterine sarcoma were included in 46 primary tumors.Conclusion 18F -FDG PET/CT has a higher specificity,accuracy as well as higher detection rate in search of multiple bone metastases,thus it is beneficial to the clinical therapy.

Objective To study the effect of different dialysis modalities on pruritus in elderly maintenance hemodialysis patients.Methods Totally 51 patients were randomly divided into hemoperfusion combined with hemodialysis group (HD+ HP),hemodiafiltration group (HDF) and hemodialysis group (HD).Plasma β2-microglobulin(β2-MG) and intact parathyroid hormone (iPTH) were measured by means of radio immunoassay at pre and post dialysis,4 weeks and 8 weeks after dialysis,cutaneous pruritus was scored.The remission rate of itching was calculated at 8 weeks after dialysis.The parameters were compared among different groups.Results The level of plasma β2-MG was lower in HD+HP group after dialysis than pre dialysis [(13.48±3.05)mg/L vs.(16.27±4.73) mg/L,t＝2.044,P＜0.05],at 4 weeks and 8 weeks after dialysis,its levels were decreased to (10.97±3.25)mg/L(t＝3.808,P＝0.002)and (6.47±2.35)mg/L(t＝7.650,P＝0.000),respectively.The levels of iPTH were also found decrease from(887.5 ± 242.7)ng/L to (688.3 ±223.4)ng/L(t＝3.384,P＝0.004)at 4 weeks and (467.2±102.5) ng/L(t＝6.578,P＝0.000) at 8weeks after dialysis in HD+HP group (all P＜0.01).There were differences of the levels of plasma β2-MG and iPTH at 4 weeks and 8 weeks after dialysis in HDF group (all P＜ 0.05),but no differences of the levels of plasma β2-MG and iPTH during every period were found in HD group(all P＞0.05).The scores of cutaneous pruritus were decreased from (21.17± 5.01) scores to (13.37±2.85) scores(t＝ 5.580,P＝0.000)at 4 weeks and (8.52±4.38) scores(t＝7.838,P＝0.000)at 8 weeks after dialysis in HD+ HP group,and also the scores at 4 and 8 weeks after dialysis in HDF group (all P＜0.01),but there were no significant differences of the scores during every period in HD group (all P＞0.05).The remission rate of itching was better in HD+ HP group than in HDF group [88.24％ (15/17 cases) vs.58.82％ (10/17 cases),x2＝14.44,P＝0.000],better in HDF group than in HD group 23.53％ (4/17 cases) (x2 ＝4.37,P＝0.037).Conclusions HD+HP is superior to HDF in efficiently clear β2-MG and iPTH,and relief cutaneous pruritus,but HD can poorly clear β2-MG and iPTH or relief itching.

Objective The purpose of this study was to evaluate gene amplification by chromogenic in situ hybridization (CISH) and the protein expression of Her-2/neu gene in patients with uterine papillary serous carcinoma ( UPSC) and to determine its prognostic value.Methods Thirty-six patients with confirmed pathologic diagnosis of UPSC in Cancer Hospital of Fudan University from Jan.1996 to Jan.2006,were analysed retrospectively.CISH was performed to assess Her-2/neu gene amplification,and protein expression was evaluated by immunohistochemistry (IHC).The prognostic factors were analyzed by log-rank test or Cox proportional hazard model.Results Among 36 cases with UPSC,13 patients (36.1% ) showed moderate staining (++) to strong staining (+++) for Her-2/neu protein,while amplification of the Her-2/neu gene by CISH was observed in 4 of the 36 (11.1% ) cases.Her-2/neu protein over-expression was significantly associated with advanced surgical stage and worse prognosis by univariate analysis ( P = 0.030 and P = 0.002,respectively),while the multivariate analysis shown that only Her-2/neu protein over-expression and deep myometrial invasion were associated with a poor prognosis ( P < 0.05 ).In 13patients with Her-2/neu protein over-expression,the mean survival period with chemotherapy was shorter than those without chemotherapy (20 vs.42 months,P = 0.370 ).Conclusion Her-2/neu protein over-expression is significantly associated with advanced surgical stage UPSC and poor survival outcome,and might reduce the chemotherapy sensitivity.

Objective To assess the efficacy of fish oil in the treatment of IgA nephropathy using the method of Meta-analysis. Methods Randomized controlled trials of fish oil in the treatment of IgA nephropathy were searched in the database of Cochrane library,PubMed, EMBASE and CNKI. Data extracted from the literatures were analyzed with Revman software (version 5.0). Results In comparison with the controlled group, proteinuria in the fish oil group was significantly decreased [SMD=-0.27, 95%CI (-0.52 to -0.03), P=0.03], while the renal function deteriorated [SMD=0.30,95%CI(0.05 to 0.55), P=0.02]. Conclusion Fish oil can decrease the proteinuria of IgA nephropathy, but can not prevent renal function from deterioration.

The disease of critically ill patients was with rapid changes, and at any time faced the risk of emergency. The current commonly used rescue vehicles were larger and bulky implementation, which were not conducive to the operation, therefore the design of a portable rescue vehicle was needed. This new type of rescue vehicle is multi-layer folding structure, with small footprint, large storage space, so a variety of first aid things can be classified and put, easy to be cleaned and disinfected. In the rescue process, the portable rescue vehicles can be placed in the required position; box of various emergency items can be found at a glance with easy access; the height of the infusion stand can adjust freely according to the user height; the rescue vehicle handle can be easy to pull and adjust accord with human body mechanics principle. The portable rescue vehicle facilitates the operation of medical staff, and is worthy of clinical application.

Objective To reproduce a stable animal model of brain death in pigs, observe the change regularity of cerebral oxygen metabolism during the process of brain death, and to evaluate the significance and value of cerebral oxygen metabolism parameters for the diagnosis of brain death. Methods Twelve landrace pigs were used to create the brain death models using modified method of increasing epidural intracranial pressure (ICP). The mean arterial pressure (MAP) and ICP were monitored continuously during the process. The pigs were divided into four groups according to cerebral perfusion pressure (CPP) decreasing degree during brain death, namely CPP normal group and CPP decreasing 0%-30%, 30%-70%, and 70%-100% groups. Blood gas analysis of the external carotid artery and internal jugular vein were monitored discontinuously. The changes in cerebral oxygen metabolism parameters, including external carotid artery-internal jugular vein bulb oxygen content difference (AJDO2), internal jugular bulb-external carotid artery carbon dioxide partial pressure difference (DPCO2) and DPCO2/AJDO2 ratio, were observed. Results Brain death model were successfully reproduced in 12 experimental pigs. With MAP and ICP monitoring, the models at different stages of CPP could be repeatedly induced. The levels of AJDO2 and DPCO2 were increased gradually and then decreased, while the ratio of DPCO2/AJDO2 was constantly increased with the decrease of CPP. The level of AJDO2 in CPP decreasing 0%-30%group was significantly higher than that in CPP normal group [(5.86±1.21)% vs. (3.92±0.64)%], the levels of DPCO2 in CPP decreasing 0%-30% and CPP decreasing 30%-70% groups were significantly higher than those in CPP normal group [mmHg (1 mmHg = 0.133 kPa): 10.33±1.83, 11.48±2.32 vs. 6.11±1.43], and the ratios of DPCO2/AJDO2 in CPP decreasing 30%-70% and CPP decreasing 70%-100% groups were significantly higher than those in CPP normal group and CPP decreasing 0%-30% group (2.81±0.53, 4.12±1.07 vs. 1.57±0.64, 1.62±0.81). All the differences above were statistically significant (all P < 0.05). Conclusions With the decrease of CPP, cerebral oxygen metabolism showed a regular change during brain death. DPCO2 combined with DPCO2/AJDO2 is a reliable blood gas analysis index indicating intracranial hypoperfusion, which has certain reference value for the determination of brain death.
