ObjectiveTo explore the therapeutic effect of continuous veno-venous hemofiltration (CVVH) on the treatment of severe acute pancreatitis (SAP).MethodsAll data about forty-five patients with SAP admitted to the intensive care unit (ICU) from June 2005 through June 2010 were reviewed.These 45 patients were randomly (random number ) divided into routine treatment group (n =22 )and comprehensive treatment group ( n =23 ).In control group,patients were rapidly given with a suffficient liquid support,vasoactive drug to increase organ perfusion,trypsin secretion inhibitor,broad-spectrum antibiotics,enteral nutrition with intestine membrane protective agent in early stage.In the comprehensive treatment group,patients received CVVH integrated with routine treatment.On admission and 72 h posttreatment,the scores of acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) and multiple organ dysfunction syndrome (MODS),and the results of standard bettery of biochemistry tests indcluding blood urea nitrogen (BUN),serum cratinine (Scr),total bilirubin (TBIL),alanine aminotransferase (ALT),amylase (AMS),C-reactive protein (CRP),TNF-α,IL-6,IL-8 were observed.Time of mechanical ventilation support,length of ICU stay,and survival rate were compared between two groups.ResultsOn admission between the two groups,no statistical significance was seen in the APACHE Ⅱ and MODS score,BUN,Scr,TBIL,ALT,AMS,CRP,TNF-α,IL-6,IL-8 (P ＞ 0.05).But APACHE Ⅱ and MODS score were decreased significantly in comprehensive treatment group than in the routine treatment group,as well as the the level of BUN,Scr,TBIL,ALT,AMS,TNF-α,IL-6,IL-8 and CRP after 72h post-treatment (P＜0.05 ).In routine treatment group and comprehensive treatment group,the time of respirator intervention and length of stay in ICU were (7.6±3.4) d vs.(11.5±4.7) d,(12.3±7.8) dvs.(17.6±9.2) d respectively,the statistical significance was shown ( P ＜ 0.05 ).Compared to the comprehensive treatment group ( 86.96％ ),the survival rate ( 59.09％ ) were lower in routine treatment group ( P ＜ 0.05 ).ConclusionsCVVH combined with routine treatment,which can remove inflammatory agents and toxins,maintain homoeostasis,and improve oxygenation,is effective in treatment of SAP and can improve patient survival rate.

0.05).The concentration of urinary KYNA,metabolite of the KYN,was significantly lower in SHRs compared to WKYs(7.8?1.8 vs 19.9?3.5 ?mol/24 h P=0.013).Both KAT activity in renal cortex and KYNA content in urine were negatively correlated to blood pressure(r=-0.418,P=0.023;r=-0.723,P=0.001).Conclusion The declined activity of KAT in renal cortex and the deficiency of KYNA concentration in urinary may affect blood pressure regulation in SHR by renal metabolite of the KYN.

Objective To explore the most effective route of mesenchymal stem cell transplantation (MSCs) in D-galactosamine (D-gal) induced porcine model with acute liver failure (ALF) and the potential mechanism.Methods BA-MA mini-pigs with D-gal-induced ALF were transplanted with porcine mesenchymal stem cells (MSCs) through four routes:intraportal injection (InP),peripheral intravenous injection (PV),hepatic intra-arterial injection (AH) and intrahepatic injection (IH).The survival time was recorded.The blood samples before and after MSC transplantation were collected for detecting liver function.Liver histology was interpreted and scored.Hepatic apoptosis and regeneration were detected by Terminal Deoxynucleotidyl Transferase dUTP Nick End Labeling (TUNEL) assay and Ki-67 assay.The protein expression of cleaved caspase-3,survivin,AKT and ERK were analyzed by Western blot.Results The average survival time in each group was (10.7 ±1.6) days (InP),(6.0 ±0.9) days (AH),(4.7 ±1.4) days (PV),(4.3 ± 0.8) days (IH) when compared with D-gal group [(3.8 ± 0.8) days].The histopathological scores revealed a significantly decrease in InP group (3.17 ± 1.04,P ＜0.05) and AH group (8.17 ± 0.76,P ＜ 0.05) when compared with that in D-gal group (11.50 ± 1.32).The apoptosis rate in InP group (25.0 ± 3.4％,P ＜ 0.05) and AH group (40.5 ± 1.0％,P ＜ 0.05) was lower than that in D-gal group (70.6 ± 8.5％).The expression of active caspase-3 was inhibited,while the expression of survivin,AKT and ERK was elevated in InP group.Conclusions The intraportal injection was superior to other pathways for MSCs transplantation.Intraportal MSC transplantation could improve liver function,inhibit cell apoptosis,promote cell proliferation and prolong the survival in porcine ALF model.

Objective To compare the effect of three methods in diagnosis of plague by detecting of Yersina pestis F1 antigen. Methods In natural foci of plague, wild animal samples, such as blood, liver, spleen,and lymphoid tissue were collected, and the three methods of enzyme linked immunosorbent assay (ELISA),reverse indirect hemagglutination assay(RIHA) and gold-immunochromatography assay(GICA) were employed to detect F1 antigen of Yersina pestis. Results Total of 414 infused organ samples of natural death and captured wild animals in natural foci of plague were determined. Positive samples detected by GICA and ELISA were the same,the positive rates were 5.31%(22/414), both positive and negative coincidence rates were consistently 100%. Only 18 samples were positive by retrial in 186 samples with more than 2 holes aggregation by preliminary examination of RIHA, with nonspecific agglutination rate of 40.6% (168/414) and positive rate of 4.35% (18/414). The positive coincidence rate was 81.82% (18/22) between RIHA with GICA and ELISA, and negative coincidence rate was statistically significant(t = 4.379, P ＜ 0.01). Conclusions ELISA, RIHA and GICA can be used for early diagnosis of plague by detecting F1 antigen. The results of RIHA have quantitative significance, with higher non-specific agglutination rate, and heavy workload of re-examination; GICA and ELISA has the same specificity and sensitivity, but the results of GICA is only qualitative. ELISA excluded the defect of RIHA and GICA, and combines the advantages of both methods.

OBJECTIVETo verify the efficacy on Parkinson's disease combined with depression treated with electroacupuncture and medication and to explore the therapeutic mechanism.

METHODSSixty cases of Parkinson's disease combined with depression were randomized into an acupuncture + medication group and a medication group, 30 cases in each one. The conventional therapeutic program of oral administration of madopar and fluoxetine was applied in both groups. In the acupuncture + medication group, on the basic treatment as the above, electroacupuncture was applied to Baihui (GV 20), Yintang (EX-HN 3), Sishencong (EX-HN 1), Taichong (LR 3) and Sanyinjiao (SP 6), etc. The level of the serum brain-derived neurotrophic factor (BDNF) and the score of Hamilton depression scale (HAMD) were observed and compared before treatment and after 3 months of treatment. The efficacy was assessed in two groups.

RESULTSThe level of BDFN was improved significantly after treatment as compared with that before treatment in two groups (both P < 0.05) and the result in the acupuncture + medication group was superior to the medication group (P < 0.05). HAMD scores were reduced significantly after treatment as compared with those before treatment in two groups (both P < 0.05) and the result in the acupuncture + medication group was superior to the medication group (P < 0.05). The total effective rate was 90.0% (27/30) in the acupuncture + medication group, which was better than 83.3% (25/30) in the medication group (P < 0.05).

CONCLUSIONThe combined therapy of electroacupuncture and medication achieves the significant efficacy on Parkinson's disease combined with depression. This therapy regulates effectively serum BDNF level, relieves depression symptoms of the patients. The efficacy of electroacupuncture combined with medication is superior to the simple medication.

Objective To analyze the clinical features, treatment outcomes and prognosis of patients with urinary tract lymphoma. Methods The clinical data of 16 patients in Tongji Hospital of Tongji University from January 2009 to April 2016 were collected and retrospectively analyzed. Results The median age of these patients was 68 years. The onset symptoms of 14 cases were related to urinary system and imaging studies of 10 cases showed masses in the urinary system. The onset regions of lymphoma included:4 cases were renal lymphoma, 5 cases were adrenal lymphoma, 5 cases were testicular lymphoma, 1 case was prostate lymphoma and 1 case was from urethral mouth. The histological type of 12 cases was diffuse large B-cell lymphoma and 10 patients were non-germinal center B cell-like (non-GCB) molecular profiling. Twelve cases belonged to Ann Arbor stages ⅢE- ⅣE, 10 cases had international prognostic index scores ≥3, and 7 cases had B symptoms. 10 patients were confirmed by surgery. Fourteen cases accepted rituximab-containing regimen chemotherapy. Five cases achieved complete response and 3 were partial response. Conclusions The clinical manifestations and imagine examination of patients with urinary tract lymphoma are lack of specificity. The clinical features are highly aggressive and most of the patients are diagnosed at advanced stage. The main histological type is diffuse large B-cell lymphoma and non-GCB molecular profiling. Treatment regimens include surgery combined with chemotherapy and radiotherapy. Earlier diagnosis and treatment may improve the survival of patients.

OBJECTIVETo investigate the effect of the basic fibroblast growth factor (b-FGF) to regenerate an autologous tissue-engineered cartilage in vitro.

METHODSThe Cells were harvested from the elastic auricular cartilage of swine,and were plated at the concentration of 1 x 10(4) cells/cm2 , studied in vitro at two different media enviroments: Group I contained Ham's F-12 with supplements and b-FGF, Group II contained Ham's F-12 only with supplements. The passage 2 cells (after 12.75 +/- 1.26 days) were harvested and mixed with 30% pluronic F-127/Ham's F-12 at the concentration of 50 x 10(6) cells/ml. It was injected subcutaneously at 0.5 ml per implant. The implants were harvested 8 weeks after the vivo culture and examined with the histological stains.

RESULTSThe chondrocytes displayed morphologically similar to the fibroblasts in the media containing basic-FGF. The number of cell doublings (after 12.75 +/- 1.26 days) in vitro culture was as the following: Group I, 70; Group II, 5.4. Eight 8 weeks after the vivo autologous implantation, the average weight (g) and volume (cm3) in each group was as the following: Group I, 0.371 g/0.370 cm3 Group II, 0.179 g/0.173 cm3 (P < 0.01). With the b-FGF in vitro culture, the cells were expanded by 70 times after 2 weeks. Histologically, all of the engineered cartilage in the two groups were similar to the native elastic cartilage.

CONCLUSIONThese results indicate that the basic-FGF could be used positively to enhance the quality and quantity of the seeding cells for the generation of the well-engineered cartilage.
