OBJECTIVE To exlpore the clinical features and countermeasures of nosocomial infections in cardiovascular patients.METHODS The infection incidence,infection sites,high-risk factors and impacts on prognosis were recorded and analyzed in a retrospective way.RESULTS Nosocomial infection incidence was 10.1% within which respiratory system infection taken the first place;patients over 60 ages and staying in hospital over 30 days,with underlying diseases,chronic heart failure,invasive operation etc were the high-risk factors;the mortality of the infected group was higher than the non-infected group.CONCLUSIONS The infection incidence in cardiovascular patients is related to various factors,with bad prognosis;we need to avoid the high-risk fators based on the active treatment for primary disease,in this way to prevent and control the occurrence of nosocomial infection.

As the incidence of prostate cancer has risen rapidly in China, it is important to optimize the workflow for the prevention and management of prostate cancer. This review analyzed the epidemiological trends of prostate cancer in both the United States and China, the comparison could provide significant evidence on how to improve prevention and management of prostate cancer. The rising incidence of prostate cancer in China is associated with lifestyle changes. The majority of prostate cancer patients have advanced disease. Screening of prostate-specific antigen is helpful in increasing the percentage of early-stage disease and ultimately improves survival.

AIM To investigate the analgesic effect of 1,6 Di (4 phenethyl 1 methyl 1 piperazinyl) hexane dibromide (97 9 G4) and its mechanisms. METHODS The writhing model of mice induced by acetic acid, hot plate test (sc, icv), tail flick test and the model of electrical stimulation induced contraction of guinea pig ileum were used. RESULTS The inhibition of writhing reaction induced by acetic acid was found (ID 50 =8 8 mg?kg -1 ) and the rising of mice pain threshold in hot plate test and in tail flick test was obvious ( P

Objective To discuss the diagnosis and outcome of multilocular cystic renal cell car-cinoma. Methods The clinic data of 1 case of multilocular cystic renal cell carcinoma were reviewed with its clinical manifestation, imaging, pathology and therapy in our hospital. The male patient aged 49 was incidentally found to have a right renal tumor. The CT scan showed a multiloeular cystic tumor in the low pole of the right kidney with a clear outline. The thin septa were found in the tumor, which were enhanced in the enhancement CT scan. The enhancement MRI showed the cystic wall was en-hanced. Results The patient received a partial nephrectomy as his treatment. The pathological char-acteristics were as following: the multilocular cystic tumor was about 3 cm×2 cm×2 cm with clear serosity in it. The cystic wall was smooth with the width of 0.1-0.2 cm. Most of the cystic cavities were covered by monostratified or stratified cubic clear cells, and some were covered by squamous epi-thelium or no epithelium at all. The septum was composed of collagen fiber, and clear cells were found in it. The clear cells form small collections but do not form expansile nodules. The final pathological diagnosis was multilocular cystic renal cell carcinoma. The follow-up was 20 months, without local re-currence or distant metastasis was found. Conclusions Multilocular cystic renal cell carcinoma (MCRCC) is a rare variant of renal cell carcinoma with a good prognosis. MCRCC is an uncommon tumor of the kidney composed of multiple cysts with clear cells in the septa indistinguishable from grade I renal cell carcinoma. Most patients are asymptomatie and the tumors are discovered inciden-tally. The preoperative diagnosis of MCRCC immediately depends on imaging studies. Pathology is the key to diagnosis.

Objective To improve the clinical diagnosis and treatment outcome of primary renal lymphoma.Methods The clinical data of one primary renal lymphoma case were reviewed with its clinical manifestation,imaging,pathological study results and treatment outcome in our institute.This was a 61 yrs female patient presented with progressive left flank pain.The abdominal CT scan revealed enlarged left kidney lost ocortico-medullary differentiation and with a lower kidney pole 9.8 cm × 8.9 cm × 8.8 cm hypodensity mass.Results The patient was diagnosed with B-cell non-Hodgkinˊs lymphoma after radical nephrectomy.Extrarenal origin was ruled out by bone marrow biopsy.The pathological results showed that the tumor was limited to the lower kidney pole.Microscopically,there were large sheets of lymphoma cell infiltration in kidney parenchyma.The lymphoma cells were oval or polygonal.The nuclei of the lymphoma cells were anachromasised and irregular in size.The final pathological diagnosis was diffused large B cell lymphoma.The patient was subsequently given six cycles of CHOP (cyclophosphamide,adriamycin,vincristine and prednisone) in conjunction with rituximab.Twenty months post chemotherapy the patient was diseas-free at follow-up.Conclusions Primary renal lymphoma is rare and the mechanism of its development is unclear.Most of the cases reported showed rapid systemic progression and poor prognosis.The clinical manifestation is similar to renal cell carcinoma.Ultrasound and CT have no distinct characteristic.Diagnosis is established on renal biopsy or radical nephrectomy.Effective post-operative treatment is chemotherapy (CHOP) in conjunction with rituximab.

Objective To discuss the diagnosis and outcome of adult endodermal sinus tumor oftestis.Methods The clinic data of 6 cases of adult endodermal sinus tumor of testis were reviewed.The patients' average age was 28 years.Five patients complained of an asymptomatic scrotal mass and1 patient complained of the pain of cryptorchidism.All patients received radical orchiectomy as initialtreatment.Pathology results suggested 2 patients with stage Ⅰ disease,3 patients with stage Ⅱ diseaseand 1 patient with stage Ⅲ disease.All were treated with chemotherapy or radiotherapy following rad ical orchiectomy.Retroperitoneal lymph node dissection(RPLND)was performed in Ⅰ case with stageⅡ disease.Results Six cases of adult endodermal sinus tumor of testis were confirmed by patholo gy.Five patients were followed up for 1.5 year to 8 years,no local recurrence and distant metastasiswere found.Conclusions Adult endodermal sinus tumor is a rare neoplasm of the germinal cell line.Pathological examination is the key to diagnosis.Postoperative combination chemotherapy and radio therapy are the most common means of this disease.

AIM: To investigate the effect of monascus purpureus fermented rice (MR) on alcohol fatty liver model in quails. METHODS: A fatty liver model was established in quails, then the lipid levels of the models were tested in both plasma and liver, and the examination in the pathological histology of liver was conducted. RESULTS: 1.6 g?kg -1 ?d -1 of MR given orally for 20 d significantly decreased TC, TG and LDL (P

To elucidate the latest progress of proteomics research of central nervous system diseases and drugs. Proteomics , an important discipline in postgenomic era, is the integrated study of protein properties on a large scale. Currently, the best established application of proteomics are in the clinical and biomedical fields. Proteomics will facilitate the elucidation of network mechanism of the development, progress and prognosis of central nervous system diseases. Proteomics offer a unique opportunity to identify disease specific proteins, accelerate the development of target driven drugs, build up molecular pharmacological models, screen and analysis of the efficacy, toxicity and side effects of potential drugs on a large scale. It is predictable that proteomics will play a tremendous role for the diagnosis, detection and pharmaceutical development of central nervous system diseases.
