Background and purpose: Primary intracranial epithelioid haemangioendothelioma (EH) was rare. This study was to discuss the clinical pathological features, radiographic findings, treatment and prognosis of primary intracranial EH combined with literature review. Methods: We reviewed a case of EH reported from our hospital, and comprehensively analyzed the related literature. Results: Based on our report and review of the literature, EH is rare and with borderline or uncertain behavior. The original tumors demonstrated specific image features. The tumor usually appeared as a small nest or cords composed of eosinophilic epithlioid or spindled cells.Immunohistochemical assay were positive for endothelial markers CD31, CD34 and FⅧ. EH may be treated with complete surgical resection whenever possible and is sensitive to radiation. The EH has a favorable prognosis. Conclusion: EH has variable malignant potential, and should be differentiated from meningioma. Total resection and close follow-up is recommended. Additional radiotherapy is advised for residual tumors.

Objective To evaluate the efficacy of DSA-guided percutaneous transhepatic gallbladder catheter drainage (PTGCD) in treating aged patients with acute cholecystitis complicated by severe diseases. Methods The clinical data of 15 aged patients with acute cholecystitis or complicated by severe diseases, who were encountered at authors’ hospital in the past three years and were treated with PTGCD, were retrospectively analyzed. The clinical results were discussed. Results PTGCD was successfully accomplished with single procedure in all 15 patients. Abdominal pain was relieved within one to three days, and the abdominal symptoms and signs subsided or disappeared. Reexamination of routine blood test showed that the white blood cell count decreased to normal range in 1 - 2 weeks, and complete cure was achieved in some patients. Secondary surgery was carried out in some patients after the clinical condition was improved. During the follow-up period no complications occurred in all patients except one who developed biliary leakage after the catheter was retrieved two weeks after the treatment. Conclusion For the treatment of complicated acute cholecystitis in aged patients who are not suitable to receive surgery, DSA-guided percutaneous transhepatic gallbladder catheter drainage is an ideal therapeutic means as it can significantly relieve clinical symptoms.

The latest findings of our laboratory showed that Angelica sinensis polysaccharide (ASP) showed a definite effect in regulating the aging of hematopoietic stem cells. Leukemia is a type of malignant hematopoietic tumor in hematopoietic stem cells. There have been no relevant reports about ASP's effect in regulating the aging of leukemia cells. In this study, human acute myeloid leukemia (AML) KG1alpha cell lines in logarithmic growth phase were taken as the study object, and were divided into the ASP group, the cytarabine (Ara-C) group, the ASP + Ara-C group and the control group. The groups were respectively treated with different concentration of ASP, Ara-C and ASP + Ara-C for different periods, with the aim to study the effect of ASP combined with Ara-C in regulating the aging of human acute myeloid leukemia KG1alpha cell lines and its relevant mechanism. The results showed that ASP, Ara-C and ASP + Ara-C could obviously inhibit KG1alpha cell proliferation in vitro, block the cells in G0/G1 phase. The cells showed the aging morphological feature. The percentage of positive stained aging cells was dramatically increased, and could significantly up-regulate the expression of aging-related proteins P16 and RB, which were more obvious in the ASP + Ara-C group. In conclusion, the aging mechanism of KG1alpha cell induced by ASP and Ara-C may be related to the regulation of the expression of aging-related proteins, suggesting that the combined administration of ASP and anticancer drugs plays a better role in the treatment of leukemia .

5.Pacing sites and modes in cardiac resynchronization therapy.
Journal of Zhejiang University. Medical sciences 2009;38(1):107-112
There are many differences between cardiac resynchronization therapy (CRT) and conventional pacing therapy in terms of indications and implant techniques. Generally speaking, CRT requires implanting 3 pacing leads in heart failure patients with ventricular dysynchrony. A left ventricular lead is implanted via intravenous coronary sinus. The pacing site of left ventricle has important influence on therapy response. Sometimes open chest implant or other pacing modes are adopted to compensate the anatomical limitation of coronary sinus and its branches. In addition, the pacing sites and modes of right atrium and right ventricle are also under research to further improve CRT response.

Objective To study the significance of DNA of Toxoplasma gondii in peripheral blood. Methods DNA of T.gondii in peripheral blood of 50 infected rats was detected by polymerase chain reaction. A pair of primers was designed, according to the sequence P30 gene specific to T.gondii, to amplify DNA from T.gondii by PCR. Results The primers amplified DNA specifically from T.gondii and could not amplify DNA from humans, uninfected rat and mouse and from Trichomonas vaginalis and Entamoeba histolytica. DNA of two Toxoplasma parasites was detected by 35 cycles of amplification, indicating a fair sensitivity of the PCR system. Conclusion PCR may have a value for early diagnosis of T.gondii infection in rat.

Objective To study the dynamic changes of cytokines including tumor necrosis factor-alpha (TNF-?),interleukin-6 (IL-6),IL-8 in serum and cerebrospinal fluid (CSF) of asphyxia neonates,and to analyze the relationship between cytokines levels and severity of brain damage and neurological outcome. Methods The concentrations of TNF-?,IL-6,IL-8 in serum and CSF were measured by radioimmunoassay in 63 asphyxia neonates. Neurological development was evaluated at 12 months by children′s developmental scale of china.Results The serum concentrations of TNF-?, IL-6,IL-8 were significantly higher in asphyxiated neonates than those in the controls,and they were correlated with the degree of encephalopathy. The level of serum TNF-? was hig-(hest) at the first day and IL-6 was highest at the third day. There was no marked dynamic changes within 5 days in serum IL-8 level. The concentrations of TNF-?,IL-8 in CSF were higher at the first and the third day.The dynamic changes of IL-6 in CSF were similar in serum and they were positively correlated. The serum concentration of IL-6 in severe brain injury group was much higher than those of normal and mild group.The CSF concentration of IL-6 in severe brain injury group was much higher than that of normal group. The CSF concentration of IL-8 in severe brain injury group was much higher than those of the normal and mild group. Conclusions The concentrations of TNF-?,IL-6 and IL-8 are increased both in serum and CSF in asphyxiated neonates which are correlated with severity of hypoxic-ischemic encephalopathy. Cytokine-mediated inflammatory reactions may participate in the mechanism of hypoxic-ischemic brain injury after asphyxiaion.The concentration of IL-6 in serum and IL-6, IL-8 in CSF are correlated with the neurological outcome.

Objective:
To explore the application of penile base staggered flap in the operation of severe hypospadias with penoscrotal transposition.
Methods:
Twenty-three cases with severe hypospadias with penoscrotal transposition were corrected by urethroplasty and staggered flap plasty in our department from May 2013 to June 2016. After urethroplasty, the skin at the junction of the penile base and scrotum was transversely cut by 1.5-2.0 cm, and then sutured with Z-plasty to reconstruct the angle of the penis and scrotum.
Results:
After the operation, infection and cracking at the suture of the staggered flap occurred in one child and was cured after dressing change and symptomatic treatment. Two cases suffered from urine leakage at the suture of the staggered flap. One of the cases realized self-healing and the other received a repair operation for urinary fistula. Three children suffered coronary sulcus fistula and was cured by urethroplasty. All the patients were followed up from 10 to 30 months with normal penis scrotal position and satisfactory appearance.
Conclusions
The application of penile base staggered flap can be used for severe hypospadias in one stage with penoscrotal transposition surgery. It is a simple and satisfactory method for the treatment of hypospadias with penoscrotal transposition.
