Objective To evaluate the prognostic factors of elderly patients with noscomial Candidemia in intensive care unit. Methods A retrospective study was carried out in 75 elderly patients with noscomial Candidemia from 2001 to 2008. Multivariate logistic regression analysis was performed to find the correlations of prognosis with clinical and biochemical parameters. Results A total of 75 Candida strains were isolated from blood. The proportion of non-albicans species reached to 70.7%. Fluconazole-resistant candidiasis was increased. Overall mortality rate was 48.0%.Multivariate logistic regression analysis showed that septic shock, comorbid bacteremia, higher serum creatinine and sequential organ failure assessment (SOFA) score more than 10 were independent predictors for in-hospital mortality (Ward=6.34, 5.15, 8.04, 6.82, all P>0.05). Conclusions Noscomical Candidemia in elderly critical illness patients leads a high mortality, the proportion of nonalbicans species and fluconazole-resistant candidiasis increase. The blood culture and drug sensitive test should be performed routinely to provide proper evidence for antifungal therapy. Monitoring the high risk factors, effective and reasonable therapeutics are the guarantee for reducing the mortality induced by Candidemia.

OBJECTIVEThis study aims to construct a long-term, osteogenesis-targeting HU-308 drug delivery implant by the layer-by-layer electrostatic self-assembly (LBL) technique, and observe the features of its delayed release in vitro.
METHODSA heparin (Hep) and chitosan (Chi) multilayer was coated on pure titanium using the LBL technique, and the titanium implants were dipped into the solution to load HU-308. The amount of loaded drug and release rates were measured using a UV-Vis spectrophotometer. The relationships between the loading efficiency, release time, and multilayer films were evaluated. The morphology of all the multilayers was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM).
RESULTSThe results showed that the Hep/Chi self-assembly multilayer was gradually fabricated on the titanium surface. HU-308 was successfully loaded on the titanium implants. The amount of loaded drug increased with the amount of multilayer films, except in the T20 group. In vitro drug release study showed that drug release was more difficult in the system with thicker films, and large amounts of multilayer films decreased the release speed. Both SEM and AFM measurements showed typical LBL deposition of Hep and Chi.
CONCLUSIONThe HU-308 drug delivery implant is successfully fabricated via LBL technology. It could provide sustained release of HU-308 over 30 d. This type of implant may provide a new possi- bility of promoting implant-bone osseointegration for osteoporotic patients.

Objective To assess the pubvaginal fascia sling cystourethropexy (PV sling) technique and outcomes of the treatment of female type Ⅲ stress urinary incontinence. Methods From October 2005 to January 2008, 9 women presenting with type Ⅲ stress urinary incontinence were treated with Pubvaginal fascia sling cystourethropexy. All the patients underwent 1 h pad test before discharge and were tested with maximum uroflow rate, volume of postal residual urine, maximum urethral close pressure (MUCP) and abdominal leak point pressure (ALPP) after 3 months. Results The operative time ranged from 60 to 90 min (mean, 75 min). Estimated blood loss ranged from 60 to 100 ml (mean, 76 ml). Intraoperative unilateral bladder perforation occurred in 2 cases. One patient with infection of abdominal incision was cured by changed dressings. The urinary catheter was removed 5 days post-operation. 4 patients had normal urination and 1 patient had urine retention. The recovery following intermittent catheterization was 3-12 days. 8 patients got 3-28 months' follow up. 7 patients were cured with 1 h pad test decreased from preoperative 58 g (45-75 g) to postoperative 1 g (0-2 g), mean residual urine was less 65 ml (0-80 ml). The values of Qmax (ml/s),MUCP (cm H2O) and ALPP (cm H2O) were 10. 5±2. 7, 15. 5±3. 4 and 40. 4±8.2 pre-opreative,and 26.5±3.9, 49.8±6.7 and 98.6± 12.2 3 months post-operative. There were significant differences of these parameters between pre-and post-operation (p<0.01). Conclusions PV sling could be a safe and effective surgical procedure fortreatment of type Ⅲ female stress urinary incontinence.

Objective To summarize the laboratory, pathologic and imaging characteristics of patients with autoimmune pancreatitis (AIP) retrospectively for early diagnosis and treatment. Methods Eleven AIP patients were selected in our hospital from 2007 to 2009. Laboratory parameters including complete blood count, tumor markers, hemodiastase and autoantibodies were tested. Abdominal ultrasonography and computerized tomography (CT) scanning were also performed. Results Five patients had elevated hemodiastase and liver enzymes, four patients had hyperbilirubinemia and three patients had hyperglobulinemia. Increased serum CA199 levels (mean 78.4 U/ml) were found in six patients. All of the 11 patients had enlarged pancreas on imaging. Four cases were treated with three months of drug therapy. After the treatment, the pancreas volumereturned to normal size, pancreatic duct and bile duct became normal in size. Seven cases received surgical operation. Pathology examination showed fibrous tissue and folliculus lymphaticus formation in the pancreas,with a large number of lymphocytes and plasma cells infiltration. Two of seven cases were diagnosed with Sj(o)gren's syndrome and rheumatoid arthritis after being followed-up for six to twelve months post-operation.Their symptoms relieved after corticosteroid and immunosuppressive therapy. Conclusion AIP is a special type of chronic pancreatitiswith characteristic laboratory, imaging and histological features. Glucocorticoid and immunosuppressive agents therapy are effective for AIP.

Objective To prepare follicle stimulating hormone (FSH) polypeptide modified nanoparticles (NP) in order to achieve specific ovarian tumor targeting. Methods Expression of FSH receptor protein in human liver cancer and ovarian cancer cell lines BEL-7402, SKOV-3 and Caov-3 was detected by immunocytochemistry. The polypeptide fragment of FSH β 81 -95 amino acids (FSHL81-95)was synthesized and covalently coupled to NP. The specific binding of FSHL81-95 and FSHL81-95-NP was examined by fluorescence microscopy and flow cytometry. Results BEL-7402 and SKOV-3 cells were negative for FSH receptor staining, while Caov-3 celia were positive. The diameters of NP were about 100 nm, with a Zeta potential of -25 mV or so. Caov-3 cells showed a more specific interaction with FSHL81-95-NP than SKOV-3 cells (4. 17 ± 0. 86 and 2. 30 ± 0. 21 ; P < 0. 05). The uptake of FSHL81-95-NP was more than NP in Caov-3 cells (4. 17 ± 0. 86 and 0. 41 ± 0. 32 ; P < 0. 05 ). FSHL81-95-NP showed a selective targeting at Caov-3 cells compared with control NP. Conclusion FSH polypeptide modified NP could selectively target ovarian cancer cells expressing FSH receptor, which might contribute to specific endocytosis mediated by FSH receptor.

Objective:To study the anti-inflammatory effect of immune milk. Method:Twenty four strains of pathogenic bacteria (including 12 strains of pathogenic E.coli, 8 strains of Salmonella, 3 strains of Shigella and 1 strain of Yersinia enterocolitica) originated from human intestinal tract were selected as antigens, and dairy cows were immunized. Results:Vaccination could not increase the concentration of IgG in the immune milk, but significantly highten the specificity of milk antibodies. The antibody titers against 24 pathogenic bacteria in immune milk was 128, 64 folds of control regular milk. Conclusion:Feeding of immune milk could inhibit edema of rat footpad induced by carrageenin and formaldehyde and the formation of acestoma of mice caused by cotton embedded hypophloedally. Meanwhile, the PGE2 level in inflammatory footpad of rat fed with immune milk was remarkably lower than that of rat fed with regular milk. These results indicate that immune milk has anti-inflammatory property.
