Objective To explore the application of monitored anesthesia care (MAC) under the guidance of bispectral index in surgical treatment of chronic subdural hematoma in elderly patients.Methods Sixty patients (33 males, 27 females, aged 65-85 years, ASA physical status Ⅱ-Ⅳ) undergoing sphenotresia drainage of chronic subdural hematoma from March, 2014 to May, 2015 were randomly divided into BIS-guided monitored care anesthesia group (group M) and local anesthesia group (group C).Propofol and remifentanil were intravenously infused into patients from group M to maintain BIS index 65-75, vital signs stability and no movement.Local anesthesia was performed before skin incision for each patient.The frequency of medication, the incidence of adverse events were record.The satisfied degree of sedation and analgesia were also evaluated.Results The frequency of movement, local anesthesia drug and additional use of esmolol, were significantly less in group M than those in group C.The satisfaction degree of sedation and analgesia were significantly higher in group M than those in group C (P<0.05).There was no significant difference of respiratory depression and airway obstruction between the two groups.No nausea vomiting reflex and respiration occurred in all groups.Conclusion Bispectral index guidance can be safely applied in surgical treatment of chronic subdural hematoma in elderly patients, which can supply more sedative and analgesic satisfaction than local anesthesia.

Objective To predict the prognosis after acute cerebral infarction using a combination of indicators. Methods Two hundred and seventeen patients with acute cerebral infarction admitted from October 2005 to December 2008 were studied. Logistic regression analysis of the data from 112 of the patients admitted from October 2005 to March 2007 was used to select 20 indicators for study. The indicators were combined into prognostic indexes using a multi-layer perception (MLP) neural network (NN) model. Data on the subsequent 105 patients were usedto appraise the model. Results The agreement of the prediction results of the NN model with the real recovery observations was rated as "excellent" in 39 cases, "OK" in 27 and "bad" in 32. The sensitivities were 95.1%,87.1% and 96.9% respectively. On average, the differences between the predicted results with the NN model andthe real recovery were not significant. Conclusion The NN model delivered good precision in predicting the outcome of acute cerebral infarction and it is worthy of further investigation.

AIM: To investigate the effects of globular adiponectin (gAd) on the expression of adiponectin receptor 1 (AdipoR1) in human umbilical vein endothelial cells (HUVECs), and on the apoptosis induced by advanced glycation end products (AGEs). METHODS: HUVECs were treated with the indicated concentrations of AGEs for 24 h or 48 h in vitro. The cells in gAd treatment group were pretreated with gAd for 24 h, and then were treated with AGEs for another 24 h or 48 h. Cell variability was quantified by MTT assay. Apoptotic cells were detected by flow cytometry with Annexin-FITC/PI double staining. AdipoR1 mRNA in the cells was determined by quantitative real time reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: The viability of HUVECs treated with AGEs decreased significantly as compared to the cells treated with HSA (control, P<0.05). Under the same condition of AGEs exposure, the viability of the cells treated with gAd was greatly higher than that of the cells without gAd treatment (P<0.01). The apoptotic rate of HUVECs was significantly elevated by AGEs treatment vs HSA treatment observed by Annexin V-FITC/PI double staining analysis with flow cytometry (P<0.05). Under the condition of AGEs stimulation, the apoptosis of HUVECs was decreased by pretreatment with gAd as compared to that of the cells without gAd treatment (P<0.01). Measured by quantitative real time PCR, AGEs decreased the expression level of AdipoR1 mRNA and gAd increased the expression of AdipoR1 mRNA contrarily (P<0.05). CONCLUSION: AGEs increase the apoptotic rate of HUVECs in a concentration dependent manner and gAd promotes the AdipoR1 mRNA expression.

Objective To evaluate the safety and efficacy of Voriconazole on invasive fungal infections in very elderly patients.Methods Clinical data of 24 very elderly patients with invasive fungal infections who had sought treatment at the Department of Geriatrics of our hospital from April 2013 to April 2014 were retrospectively investigated.The classifications and quantities of fungi,accompanying symptoms,adverse reactions,blood tests,and liver and kidney function indicators were recorded and analyzed before and after treatment.Results Each of the 24 cases was found to have been infected with one or more of 17 fungal strains belonging to the genus of Candida.The rate of complete fungal elimination after treatment was 70％ (12/17).Of the 24 cases,5 achieved a full recovery(20.8 ％),10 (41.7 ％) had significant improvement,5 (20.8 ％) had some improvement,and 4 cases(16.7％)showed no therapeutic benefits,with a total effectiveness rate of 62.5 ％.There was no significant difference in liver and kidney function before and after treatment(P＞0.05).A transient increase in serum creatinine occurred in 1 case and defective vision in another patient during Voriconazole treatment.Conclusions The incidence of invasive fungal infections is high in very elderly patients,with Candida as the main pathogen.Voriconazole is effective in treating invasive fungal infections in very elderly patients,and close monitoring of liver and kidney function is required during voriconazole treatment.

Objective To discuss the safety and efficacy of retroperitoneal laparoscopic partial nephrectomy in the treatment of unilateral multifocal renal tumors.Methods The data of 12 patients with unilateral multifocal renal tumors managed with retroperitoneal laparoscopic partial nephrectomy between 2009 and 2012 were reviewed retrospectively.The 12 patients had a mean age of 42 years (28 to 62) and body mass index of 23.5 kg/m2 (18.6 to 29.3),including 4 males and 8 females.Four cases were in the left side,7 cases were in the right side,and 1 case had bilateral renal tumors.The diameter of renal tumors ranged from 0.5 cm to 4.7 cm,and all tumors were projected on the surface of kidney.Nine cases were diagnosed as renal cell carcinoma,and 3 cases were diagnosed as angiomyolipoma before operation.All patients underwent retroperitoneal laparoscopic partial nephrectomy under general anesthesia,while 1 patient with bilateral renal tumors experienced radical nephrectomy of the contralateral renal tumor 3 months after the first operation.Results All the oprations were successful without conversion to open surgery.The mean renal artery cut off time,operative time,estimated blood loss and hospital stay were 36 min (26-60),126 min (75-184),142 ml (50-300) and 5 d (3-9),respectively.No complication occurred and 1-week postoperative serum creatinine was (78.1 ±8.1)μmol/L.Histopathological study revealed 9 cases of renal cell carcinomaand 3 cases of angiomyolipoma.During the follow-up for 33 months (13-51),1 patient with yon Hippel-Lindau syndrome was operated with ipsilateral radical nephrectomy for a local recurrence while the remains had no local recurrence or metastasis.Conclusions For localized and exogenous unilateral multifocal renal tumors,retroperitoneal laparoscopic partial nephrectomy is feasible and safe.Those who have hereditary and/or malignant renal tumors should be monitored closely.

Objective To compare the safety and efficiency of retroperitoneal laparoscopic and transperitoneal laparoscopic radical nephrectomy by meta-analysis.Methods A systematic review of the literature about laparoscopic radical nephrectomy was performed,searching Medline,Embase,Cochrane library,CBM,CNKI,VIP and Wan Fang database from January 2000 to October 2012.The key words were transperitoneal,retroperitoneal,laparoscopy,radical nephrectomy.Two researchers evaluated the quality of included studies.A meta-analysis was conducted using Review Manager 5.0 software.Results Nine controlled clinical studies were concluded,including 1 306 patients (520 in retroperitoneal group and 786 in transperitoneal group).The extracted data were comparable.Meta-analysis results showed that significant difference existed in operative time and complication rate (OR =16.23,95％ CI 1.62,30.84; OR =2.44,95％CI 1.35,4.41) (P＜0.05).It seemed that the retroperitioneal laparoscopic radical nephrectomy was prior to the transperitoneal laparoscopic radical nephrectomy in those items.There was no significant difference between transperitoneal and retroperitioneal laparoscopic radical nephrectomy in incision length,estimated blood loss,stay-in hospital,conversion rate,5-year disease-free survival and 5-year overall survival (P＞ 0.05).Conclusions Retroperitoneal laparoscopic radical nephrectomy demonstrated significant lower operative time and complication rate than those in transperitoneal laparoscopic radical nephrectomy.However,there is no significant difference in efficacy.Each center can choose a modality according to their convention.

Objective To investigate the efficiency of transduction of recombinant adenovirus-mediated human endothelial nitric oxide synthase (eNOS) into lung tissue by repeated intratracheal transfection in rats.Methods Sixty 3-4 month old male Wistar rats weighing 220-280 g were randomly divided into 2 groups:control group (group C,n =10) and eNOS gene transduction group (group T,n =50).The animals were anesthetized with intraperitoneal 10％ chloral hydrate 35 mg/kg,tracheally intubated and mechanically ventilated (VT 2.5 ml,RR 60 bpm,FiO2 1.0).Recombinant adenovirus carrying human eNOS gene was given as gift by Professor Gerard from Texas University,Southwest Medical Center.In group T 50 μl of the recombinant adenovirus in concentration of 5 × 109 PFU/ml was instilled into trachea every 5 minutes for 12 times,while in group C equal volume of vector conservation solution was instilled instead.Pulmonary arterial blood samples were obtained at 2,5,7,14 and 21 d after intratracheal transfection (n =10 at each time point) for determination of serum NO concentration.The animals were immediately sacrificed after blood sample collection for determination of expression of eNOS protein in the lung tissue and RNA.The eNOS expression in the trachea,bronchus,lung,liver,spleen and kidney was detected by immuno-histochemistry.Results The serum NO concentrations were significantly higher at all time points in group T than in group C.The eNOS expression was detected in the epithelial cells of trachea and bronchi,and endothelial cells of alveoli and pulmonary blood vessels in group T but not in group C.eNOS expression was not detected in liver,spleen and kidney at 7 d after intratracheal transfection in group T.Conclusion Human eNOS gene mediated by recombinant adenovirus was transducted into rat lung tissue with normal enzyme activity by repeated intratracheal administration without being detected in distant organs.
