Objective To assess the value of emergency interventional embolization in treating traumatic spleen rupture. Methods A total of 74 patients with traumatic spleen rupture, who were encountered at authors’ hospital during the period from July 2007 to July 2013, were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into embolization group (n = 38) and surgery group (n = 36). Interventional splenic artery embolization was carried out in the patients of the embolization group, and surgical repair was employed in the patients of the surgery group. The operation time, the amount of blood loss during the procedure, the hospitalization days, the preservation rate of the spleen and the occurrence of procedure- related adverse events were recorded, and the results were compared between the two groups. Results No significant difference in the operation time existed between the two groups (P = 0.061). The amount of blood loss during the procedure, the hospitalization days and the occurrence of procedure- related adverse events in the embolization group were significantly lower than those in the surgery group (P < 0.05), while the preservation rate of the spleen of the embolization group was significantly higher than that of the surgery group (P = 0.026). Conclusion Emergency interventional embolization is a safe procedure for the treatment of traumatic spleen rupture, this technique can improve the preservation rate of the spleen when compared with traditional surgical repair treatment.

Objective To analyze the changes in the protein expression profile of peripheral blood mononuclear cells in systemic lupus erythematosus patients. Methods Peripheral blood was obtained from SLE patients and healthy controls, then mononuclear cells were isolated and the total protein was extracted by one-step method. Two-dimensional gel electrophoresis was performed and then stained with silver. Protein maps were analyzed and differentially expressed protein spots were detected using ImageMaster 2D Platinum 5.0 software. Results Match rates of (71±4)% and (72±4)% was obtained from gels from controls and pati-ents respectively. 791±17 spots were detected from control gels and 781±17 from patient gels. Eleven protein spots were up-regulated and 9 were down-regulated in SLE patients. Five proteins were identified by MS analysis, some of which had previously been shown to play a potential role in the pathogenesis of SLE. Conclusion There are significant changes in the protein expression of peripheral blood mononuclear cells in systemic lupus erythematosus patients. This study could be used as a preliminary work for better understanding of the pathogenesis and immune regulation pathways of SLE from an integrated lymphocyte protein profile perspective.

Objective To study laparoscopic pelvic lymphyectomy combined with vaginal hystectomy in the treatment of patients with stage Ⅰ endometrial carcinoma.Methods The data of 77 patients with stage Ⅰ endometrial carcinoma were reviewed retrospectively. These patients divided into the laparoscopic group and abdominal group according to the operation style. The operation time, blood loss, postoperation complication, rehabilition of the digestion tract, satisfaction degree to the operation of two groups were compared.Results There was no serious complications in the both groups. In the laparoscopic group, the operation time was longer than the abdominal group ( P<0.01), but so far as to the blood loss, the time of rehabilition of the digestion tract, the number of lymphyectomy, the postoperation pain alleviation and the degree of postoperation depression were superior to the abdominal group ( P<0.01).Conclusion Though the Laparoscopic operation takes longer time than the abdominal operation, it has much more advantage: mimimal blood loss, minimal abdominal scar, rapid postoperation rehabilition, much better pain alleviate, less urine retention.

3 cases with esophageal fistula following anterior cervical fixation were reported. The diagnosis, treatment, nursing and prevention were summarized with literature.

The immune system is a complex system involving multiple organs,and it is vulnerable to age,gender,environment and other factors.For a variation normal physiological range,it is a great challenge to evaluate drug-induced immunotoxicity in preclinical safety study.Histomorphologic assessment of the immune system is a recognized cornerstone in the identification of immunotoxicity at present.In this paper,the principles of pathological evaluation for immune system,and pathological evaluation for important immune organs including thymus,spleen,lymph nodes are discussed briefly,so that it is intended to assist toxicity pathologists in the accurate and consistent characterization of intended and unintended drug-induced alterations of the immune system.

Objective To explore the clinical significance of second transurethral resection (TUR) in patients with T1 urothelial cell carcinoma of the bladder.Methods The 142 cases with urothelial carcinoma were recruited.All patients underwent transurethral resection of bladder tumor (TURBT) and were diagnosed as stage T1 urothelial carcinoma of the bladder.The 68 of 142 cases underwent second TUR after the initial surgery.Tumor recurrence rate,progression rate and recurrence-free survival were compared.Results There were no statistical differences in age,gender,follow-up time,number of tumors,size of tumors or grade of tumors between patients with and without second TUR.Of the 68 cases that underwent second TUR,25 cases (36.8%) had residual tumor and 6 of them (8.8%) had muscle-invasive bladder cancer.After an average observation for 26.8 months,patients who underwent second TUR showed lower recurrence rate,higher recurrence-free rate and longer recurrence-free survival than patients without second TUR [37.1% vs.58.1%,x2=5.962,P=0.015;41% vs.35.1%,x2=8.502,P=0.004;21 months vs.12 months,U= 1584,P= 0.002].While the progression rate showed no statistical difference between them (14.5% vs.25.7%,x2 =2.570,P=0.109).Conclusions Second TUR provides an effective way to completely excise tumor.Second TUR is beneficial to the decrease of recurrence rate and improvement of recurrence-free survival.However,its effect on tumor progression needs further discussion.

Objective To initially understand the condition of quality of life (QOL) and depression as well as the correlation between them in the stroke inpatients. Methods 56 stroke patients from September 2014 to January 2015 in our hospital were included. Their QOL and depression status were evaluated with Stroke-Specific Quality of Life Scale (SS-QOL) and Self-rating Depression Scale (SDS). The de-pression was as the dependent variable, the score of SS-QOL, gender, age, education background, and the duration of stroke were as the inde-pendent variables, and analyzed with Logistic regression. Results Depression correlated with SS-QOL score (OR=0.955, P<0.05), but not with gender, age, education background, and the duration of stroke (P>0.05). Conclusion The depression status correlated with the QOL of stroke patients, but did not with gender, age, education background and the duration of stroke.

Toxicological pathology is a morphological elucidatet ion of tissue damage caused by drug toxicity,including damage type,location,severity grade and prognosis.It provides objective and accurate data to support preclinical drug safety evaluation.Therefore,toxicological pathology plays an important role in drug safety evaluation,and the pathologic data or conclusion often determines the termination or continuation in many drug development projects.In this paper,the characteristic of toxicological pathology,standardized management,the development of new techniques including in situ hybridization,laser scanning cytometry and laser capture microdissection,and related problems in pathology are discussed briefly.
