Objective To investigate the clinical and pathological characteristics as well as immunophenotypes of subcutaneous panniculitis-like T-cell lymphoma for its differential diagnosis with other similar diseases.MethodsThe clinical、histological and immunophenotypic features of 6 cases were described in detail and related literatures were reviewed.Results All of 6 patients presented with subcutaneous nodules or /and erythematous plaques without lymph nodes swelling and with 5 cases had fever,one case developed to ulcer from its nodules.All of 6 patient presented typical histological changes and 2 of them associated with prominent hemophagocytic syndrome.The neoplastic cells were of T-cell phenotype.Two patients under went an aggressive clinical course with short survival period of 9～16 months and four patients who treated with chemotherapy have an improved survival state,but two of them had recurrence.Conclusion SPTCL is a uncommon type of T-cell lymphoma with clinical and pathological characteristics,and it needs to be differentiated from benign panniculitis or other lymphomas of the skin.

Objective To compare the therapeutic effect of anatomic plate (AP)and locking compression plate(LCP) in treatment of fermoral intertrochanteric fracture in elderly patients. Methods Nineteen and three patients with fermoral intertrochanteric fracture were treated with anatomic plate (AP) and locking compression plate (LCP). The therapeutic effects were compared in the study. Results All operations were done successfully. Of all cases,72 patients were followed up for 5-24 months. Excellence rate: AP was 66. 7% and LCP was 88. 2%.Conclusions AP had significantly low excellence rate with more complications when compared with LCP. LCP could be the first choice in treatment of fermoral intertrochanteric fractures with high excellence rates and few complications.

Objective To investigate the change of CD8+T lymphocyte non-cytotoxic antivirus response(CNAR)in slow progressors infected by HIV.Methods Applying with density gradient and immunomagnetic beads methods to purify the CD4+T lymphocyte from the healthy person and CD8+T lymphocyte from HIV-infected individuals.The CD4+T cell was infected by HIV(SF-33)virus and cocuhured with CD8+T cell.The culture supernatant was collected and the p24 value was detected by ELISA method.Results Our study showed that the CNAR function decreased by turns of slow progressors(SP),typical progressors(TP),health control group and AIDS group.There was significant difference between groups(P<0.01).We found a significant positive correlation between the CIM+T cell ture count and the CNAR function.The virus load didn't statistically correlate with the CNAR function.Conclusion The CNAR function possibly protected the HIV-infected individuals from progression.

Objective To evaluate the effects of low dose intravenous minocycline postconditioning on myocardial ischemia-reperfusion injury in rat,and to investigate the possible mechanisms. Methods Forty-eight male wistar rats were randomly divided into four groups:sham-operation (SO)group,ischemia-reperfusion(IR)group,low-dose minocycline(3 mg/kg,LM)group and high-dose minocycline(10 mg/kg,HM)group. The rat model of myocardial IR was established by occlusion of the left anterior descending coronary artery for 45 minutes and reperfusion for 120 minutes.After the reperfusion,the parameters of haemodynamics were recorded;creatine kinase MB(CK-MB),cardiac troponin-I(cTn-I),malond-ialdehyde(MDA),superoxide dismutase(SOD)in serum and myocardium,myocardial apoptosis index(AI)and the myocardial tissue morphology were determined. Results Compared with IR group,LM and HM treatment significantly reduced the levels of CK-MB form,cTn-I,AI and MDA, lowered LVEDP,enhanced LVSP and ±dp/dtmax,elevated the activity of SOD in serum and myocardium(P<0.05). The effect of HM is stronger than LM on these above mentioned indicators,but the difference was not statistical significance(P>0.05). Conclusion LM postconditioning can protect against myocardial IR injury,and the protective effect may be related to the scavenging of oxide free radical,which further restrain the reac-tion of lipid peroxidation and apoptosis.

Objective To compare the cardiac structure and function between diabetic and non-diabetic with different peritoneal transport type.Methods A total of 84 patients with continuous ambulatory peritoneal dialysis (CAPD) in our center for 6 months were enrolled in this study.Forty-six patients of subjects were diabetic,another 38 were non-diabetic.Patients were divided into four groups according to the results of peritoneal equilibration test (PET) and the ratio of creatinine concentration in dialysate solution and plasma (D/P creatinine concentration).Patients with D/P creatinine concentration ＞ 0.65 were with high permeability and otherwise were low permeability.The four groups were diabetic-H (high permeability) group,diabetic-L(low permeability) group,non-diabetic-H (high permeability) group,non-diabetic-L (low permeability) group.The levels of left atrial diameter (LAD),left ventricular diameter(LVD),interventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),left ventricular ejection fraction(LVEF) were measured before and after 6-month peritoneal dialysis by ultrasonic doppler.Results Before peritoneal dialysis,there were no significant difference in the terms of all parameters among four groups(P ＞0.05).After 6 months of peritoneal dialysis,the albumin levels,IVST,LVPWT and LVEF in diabetic-L group,non-diabetic-L,diabetic-H group and non-diabetic-H group were ((36.57 ± 3.34),(37.21 ± 4.12),(34.19 ± 3.98),(34.51 ± 4.52) g/L respectively;F =9.034),((10.45 ± 1.12),(10.17 ± 1.35),(11.32 ± 1.09),(11.46 ± 1.38) mm respectively;F =7.525),((9.58 ± 1.42),(9.47 ± 1.31),(10.71 ± 1.40),(10.15 ± 1.41) mm respectively; F =4.963) and ((63.98 ± 4.73) ％,(63.92 ± 5.17) ％,(60.12 ± 5.12) ％,(61.43 ± 5.57) ％respectively ;F =6.984),and the differences were statistic significant (P ＜ 0.05).Compared to diabetic-H group and non-diabetic-H group,there were significant difference in the terms of all above indexes between diabetic-L group,non-diabetic-L (P ＜ O.05).Conclusion The peritoneal transport.type of diabetic patients is high permeability,which might be an important factor affecting cardiac complications in patients.

Objective To study the effect of mixed purified autogenic and allogeneic hematopoietic stem cell transplantation for the treatment of systemic lupus erythematosus. Methods Thirty-six MRL/lpr mice were randomly divided into the control group, the study group,the mixed group ( the ratio of autogenic to hematopoietic stem cells, mixed in different proportions were infused intravenously after 60Co irradiation. The study group were treated with daily intraperitoneal infusion of dexamethasone 1 mg·kg-1·d-1, while the control group were treated with intraperitoneal infusion of equivalent volume of saline daily. The changes of serum creatinine level, the urine protein excretion of the mice and blood WBC count were compared. Repeat measures ANOVA was used for data analysis. ELISA was used for anti-nuclear antibody detection Light microscopy, electronic micros-copy, immunofluorescence were applied to detect the pathological changes in renal tissue. Results Serum creatinine and urine protein excretion levels increased with time in the ontrol group, while those of the transplant group and the study group decreased. The reduction in mixed transplantation group and the study group was more evident compared with that of the allogeneic group. The difference was statistically significant (P＜0.05), but there was no significant difference between the mixed transplantation groups and the study group (P＞0.05). The histopathologic damage was most serious in the control group as pathological injury score of most mice were in grade 3 or 4. The majority of the histopathologic damage of the allogeneic group was in grade 2. Most f pathological damage of the study drug group and the mixed transplantation group were grade 1 or 2. Conclusion Mixed hematoopoietic stem cell transplantation for the treatment of murine systemic lupus erythematosus can effectively correct heavy proteinuria in murine systemic lupus erythematosus so improve the renal damage. It is a safe and effectively way to treat murine systemic lupus erythematosus.

Objective To investigate the value of clinical parameters in predicting the initiation of renal replacement therapy(RRT) in acute kidney injury (AKI) patients with cardiorenal syndrome (CRS).Methods A total of 75 AKI patients hospitalized with CRS were enrolled.All patients received pharmacologic therapy on the beginning 3 days.The patients whose heart function improved were divided into control group (n=39),and the patients whose heart function worsened were divided into RRT group (n=36).Clinical and laboratory data on the first day and the fourth day were collected and analyzed.The factors on the first day were labeled asⅠ ,and those on the fourth day were labeled asⅡ. The ratio of some parameters calculated were labeled asⅡ/Ⅰ .Area under curve (AUC) of receiver operating characteristic curve (ROC) of these factors was used to evaluate the sensitivity and specificity in predicting the initiation of RRT.Results The patients in RRT group had significantly higher levels of BNP-Ⅱ,BNP Ⅱ / Ⅰ and creatinine Ⅱ / Ⅰ (P ＜ 0.01),and lower levels of 24 hours urine volume-Ⅰ and 24 hours urine volume-Ⅱ (P ＜ 0.01).From ROC curve analysis,the AUC of 24 hours urine volume-Ⅰ,24 hours urine volume-Ⅱ,creatinine Ⅱ / Ⅰ,BNP-Ⅱ levels and BNP Ⅱ/Ⅰ to predict RRT were 0.736,0.875,0.747,0.779 and 0.894 respectively.When the cutoff values of 24 hours urine volume-Ⅰ,24 hours urine volume-Ⅱ,BNP-Ⅱ levels,BNP Ⅱ / Ⅰ and creatinine Ⅱ / Ⅰ were 905 ml (sensitivity 75％,specificity 94.9％),1450 ml (sensitivity 75％,specificity 100％),3360 ng/L (sensitivity 72.2％,specificity 100％),1.37 (sensitivity 75％,specificity 100％) and 1.25 (sensitivity 72.2％,specificity 94.4％) respectively,the value of the parameters to predict RRT was high.Conclusions The 24 hours urine volume,BNP levels after treatment and the dynamic changes of BNP levels and creatinine levels can be used as predictors of the initiation of RRT in the AKI patients with CRS.

One influenza H3N2 virus, A/swine/Shandong/3/2005 (Sw/SD/3/2005), was isolated from pigs with respiratory disease on a farm in eastern China. Genetic analysis revealed that Sw/SD/3/2005 was a triple-reassortant virus with a PB2 gene from human-like HIN1, NS from classical swine H1NI, and the remaining genes from human-like H3N2 virus. These findings further support the concept that swine can serve as reservoir or mixing vessels of influenza virus strains and maintain genetic and antigenic stability of viruses. Furthermore, we have successfully established a reverse genetics system based on eight plasmids and rescued Sw/SD/3/2005 through cell transfection. HI tests and RT-PCR confirmed that the rescued virus maintained the biological properties of the wild type Sw/SD/3/2005. The successful establishment of the reverse genetics system of Sw/SD/3/2005 will enable us to conduct extensive studies of the molecular evolution of H3N2 influenza viruses in swine.

Objective To investigate the efficacy of percutaneous transhepatic variceal embolization (PTVE) with Cyanoacrylate (TH glue) in treating large gastric fundal variceal bleeding.Methods PTVE was performed on 24 patients with TH glue injected into the main stem of left gastric vein and its fundic branches.The degree of varices in gastric fundus,rebleeding rate and survival rate after the procedure were compared with those before.Results Varices in gastric fundus were all embolized successfully with TH glue.The diameter of varices was reduced to below 5mm or disappeared in 20 patients (83.3％),and reduced to 5-10mm in the other 4 ( 16.7％ ) During the follow-up period of 3-36 months(mean 16.6 months),the rebleeding rate and mortality were 12.5 ％ ( 3/24 ),and 12.5 ％ (3/24),respectively.One patient died of liver cancer,and two others died of chronic liver failure.Conclusion PTVE with TH glue is of ideal therapeutic effect to block the feeding veins of large gastric fundal varices.

AIM: To explore whether tumor necrosis factor-α (TNF-α) induces necroptosis in murine long bone osteocyte-like cell line MLO-Y4 and the possible mechanism.METHODS: The MLO-Y4 cells were divided into control group, TNF-α group, TNF-α+necrostatin-1 (Nec-1) group, TNF-α+Z-VAD group and TNF-α+receptor-interacting protein 3 (RIP3)-siRNA group.The death rate of MLO-Y4 cells was assessed by flow cytometry with Annexin V-FITC/PI staining.The morphological features of the cells were observed under transmission electron microscope (TEM).The protein levels of RIP1, RIP3 and cleaved caspase-3 were determined by Western blot.Finally, the numbers of total cells and RIP1-RIP3-positive cells were observed under laser scanning confocal microscope.The production of reactive oxygen species (ROS) in the cells was measured by DCFH-DA staining.RESULTS: Compared with control group, the apoptotic or necroptotic rate of the cells induced by TNF-α was increased significantly (P<0.01).The increased apoptotic or necroptotic rate was dramatically reduced by treating with Nec-1, Z-VAD or RIP3-siRNA transfection (P<0.01).In TNF-α group and TNF-α+Z-VAD group, a lot of MLO-Y4 cells with typical necroptotic morphological features were observed under TEM.However, obvious necroptotic cells were not found in Nec-1 or RIP3-siRNA treatment group.The protein level of RIP1 in the cells treated with Nec-1 was sharply lower than that in TNF-α group (P<0.01).However, Z-VAD did not reduce the elevated levels of RIP1 and RIP3.RIP3-siRNA effectively down-regulated the protein level of RIP3 compared with TNF-α group (P<0.01).Nec-1 effectively down-regulated the protein levels of RIP1 colocalized with RIP3 compared with TNF-α group (P<0.01).However, Z-VAD did not reduce the levels of RIP1 colocalized with RIP3.Nec-1, Z-VAD and RIP3 siRNA significantly decreased the ROS levels (P<0.01).CONCLUSION: TNF-α induces the necroptosis of MLO-Y4 cells.RIP3 play vital roles in the cell necroptotic signal pathway.ROS may be the executor of necroptosis of MLO-Y4 cells.
