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.

AlM: To evaluate the clinical efficacy of canalicular intubation combined with external dacryocystorhinostomy ( ext-DCR ) for treatment of chronic dacryocystitis and upper lacrimal duct stenosis.
METHODS:Thirty-three patients (33 eyes) with chronic dacryocystitis and upper lacrimal duct stenosis who underwent canalicular intubation combined ext-DCR were retrospective analyzed. The silicon tube was indwelt for 6mo. All cases were re-examined 1wk;1, 3, 6, 9mo post-operation, flow of tears, pus excretion and lacrimal duct clearance were observed.
RESULTS: Clear lacrimal duct ratio was 100% in all cases during 1wk~6mo post-operation; Silicon tube was removed 6mo post-operation, 3mo after tube removal, rechecking reported 32 cases with clear lacrimal duct (97%) and 1 case with resistant duct (3%). Two cases ( 6%) with minor lacerations, no other complications were observed.
CONCLUSlON: Canalicular intubation combined ext-DCR is an effective treatment for chronic dacryocystitis and upper lacrimal duct stenosis.

Objective To study whether the measure of consumption of iodized salt to prevent iodine deficiency disorders could lead to residents excessive iodine intake in the coastal areas in China.Methods A large population-based cross-sectional study was carried out in four typical costal provinces along the coastline from north to south,including Liaoning,Shanghai,Zhejiang and Fujian.In addition to survey all of its area of Shanghai,the other three provinces' investigation was carried out at urban and rural levels,respectively,including 5 costal cities,5 costal villages and 3 inland rural areas(as a control point) in each province.In each investigated spot,the local water iodine,residents qualified iodized salt consumption rate,per capita daily intake of salt and urinary iodine levels in different populations were investigated.Results A total of 7552 copies of drinking water samples,7996 salt samples and 9873 urine samples of different populations(adults,lactating women,pregnant women and children) were collected from the 4 provinces.Except the coastal cities and counties of Zhejiang province,the qualified iodized salt consumption rates at household were all greater than 90％ in the investigated spots.The median urinary iodine(MUI) of adults and children investigated in the costal areas were in the range of 100 - 299μg/L.The MUIs of lactating women of all investigated areas were all greater than 100 μg/L.The MUI of pregnant women was at an insufficient iodine level which was lower than 150 μg/L in Shanghai,the costal cities of Zhejiang and the coastal counties of Fujian.Conclusions The overall level of iodine nutrition of coastal residents is appropriate; and it is insufficient among pregnant women in some coastal areas; coastal areas should adhere to the salt iodization measures to control iodine deficiency disorders.

Objective To investigate the effects of simvastatin preconditioning on the pulmonary heme oxygenase-1 (HO-1) expression in rats with lung injury induced by ischemia-reperfusion (I/R) of hind limbs. Methods Forty-eight adult male SD rats weighing 250-300 g were randomly divided into 6 groups ( n = 8 each) : sham operation group (group S) ; I/R group; I/R + simvastatin 1,5, 10 mg/kg groups (S1 , S2, S3 groups) ; simvastatin control group (group SC) . I/R of hind limbs was produced by occlusion of bilateral femoral arteries for 2 h followed by 3 h reperfusion. Croups S1 , S2 , S3 received simvastatin 1, 5, 10 mg/kg respectively via an oro-gastric tube for 3 days before I/R. Group SC received simvastatin 10 mg/kg via an oro-gastric tube for 3 days. Arterial blood samples were taken at 3 h of reperfusion for blood gas analysis and PaO2 and PaCO2 were recorded. The animals were then sacrificed and the lungs removed immediately for pathologic examination and determination of the wet/dry lung weight ratio (W/D ratio), superoxide dismutase (SOD) activity and polymorphonuclear neutrophil (PMN) count . Hie expression of HO-1 mRNA and protein in lung tissues was detected using RT-PCR and Western blot analysis respectively.Results Alveolar edema, localized pulmonary atelectasis and large amount of PMN infiltration were found in I/R group and were ameliorated in S1, S2, S3 groups. Compared with group S, PaO2 and PaCO2 were significantly decreased in I/R group, W/D ratio and PMN count were increased and SOD activity was significantly decreased in I/R, S1 , S2 groups, and expression of HO-1 mRNA and protein was up-regulated in the other five groups ( P ＜ 0.05). PaO2, PaCO2 and SOD activity were significantly increased, W/D ratio and PMN count were significantly decreased, and HO-1 mRNA and protein expression was up-regulated in S1, S2 and S3 groups as compared with I/R group ( P ＜ 0.05 or 0.01). W/D ratio and PMN count were gradually decreased, SOD activity was gradually increased, and HO-1 mRNA and protein expression was gradually up-regulated in S1, S2 and S3 groups. Conclusion Simvastatin preconditioning has protective effect against lung injury induced by I/R of hind limbs in rats through up-regulation of HO-1 expression in the lung tissues and in a dose-dependent manner.

A rarely reported postoperative complication following biliary surgery,and to discuss its possible mechanism.This article summarizes I reported HSB case that developed after laparoscopic cholecystectomy in our department and 9 other cases reported in literature.HSB occurred most frequently after simple cholecystectomy in addition to post operative bile duct exploration with cholecystectomy or endoscopic retrograde cholangiopancreatography.The main clinical presentation of HSB was paroxysmal colic in the upper abdomen early in the postoperative period,which could be induced after a meal.Imaging revealed subcapsular hepatic fluid collection,and successful treatment involved placement of a percutaneous drain in the biloma.The mechanism of HSB still needs to be clarified even though it is a rarely reported postoperative complication following biliary surgery.We hypothesize,after analyzing these 10 cases,that sphincter of Oddi dysfunction after biliary surgery and the subsequent persistence of high biliary system pressure may be the root cause of HSB formation.More awareness should be paid to the changes of the sphincter's motility after biliary surgery and its related complications (biliary colic,HSB etc.).

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 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.
