Objective To investigate the associations between levels of perioperative biochemical markers of the liver,kidney,lung and heart and death within 3 months postoperatively in the senile patients with femoral intertrochanteric fracture.Methods A retrospective study was conducted on the 153 senile patients with femoral intertrochanteric fracture who had been treated at Nanfang Hospital from January 2010 to January 2012.They were 71 men and 82 women,with an average age of 83.1 years.There were 70 stable and 83 unstable fractures.At preoperation (within 24 h after admission),and 24 h,25 to 48 h and 72 h postoperation,all the patients had blood examinations of biochemical markers of the liver [alanine aminotransaminase (ALT)],kidney (creatinine and urea nitrogen),lung (PaO2) and heart [brain natriuretic peptide (BNP)].The levels of biochemical markers at all time points and clinical data were compared between the living patients and those who died within 3 months postoperatively.Univariate and multivariate logistic regression analyses were conducted to estimate the independent risk factors for mortality within 3 months postoperatively.Results Of the 153 patients,32 (20.9％) died within 3 months postoperatively,including 10 men and 22 women.In the dead and surviving patients,there were respectively 25 and 17 cases who were rated as level Ⅲ or Ⅳ by ASA (American Society of Anesthesiologists).The levels of ALT,creatinine,urea nitrogen,and BNP increased to different extents while the level of PaO2 decreased postoperatively in both the dead and surviving patients.The differences between the dead and surviving patients were statistically significant (P ＜ 0.05).Multivariate logistic regression analysis showed poor preoperative physical condition (ASA level Ⅲ or Ⅳ),increased creatinine level at 25 to 48 h postoperation,decreased PaO2 at 72 h postoperation,and increased BNP level at 24 h postoperation were independent risk factors for early mortality in senile patients with femoral intertrochanteric fracture.Conclusions Femoral intertrochanteric fracture in senile patients may lead to changes in the liver,kidney,lung and heart.Prompt and dynamic monitoring of the levels of PaO2,creatinine and BNP may provide timely prediction of the poor prognosis.

Objective To evaluate the efficacy of preoperative regional intra-arterial chemotherapy (RIAC) in the treatment of resectable pancreatic head carcinoma. Methods The clinical data of 50 patients with resectable pancreatic head carcinoma who had been admitted to the Research Institute of Pancreatic Diseases of Fudan University from December 2006 to July 2007 were retrospectively analyzed. Patients were randomly divided into2 groups (n =25 in each group): patients in group A were treated with preoperative RIAC followed by regional pancreaticoduodenectomy, and patients in group B were treated with surgical procedure routinely. The lymphatic metastases in the 50 specimens of pancreatic head carcinoma were detected by histological examination with hematoxylin and eosin (HE) staining, and lymphatic micrometastases were detected by immunohistochemical method with staining of cytokeratin AE1/AE3 in 10 specimens with negative HE staining of the lymph nodes in each group. Results There was no significant difference in the incidence of complications, the length of hospital stay and the 1-, 2-year survival rates between the 2 groups (χ2 = 0.12, 2.88, P > 0.05). The incidence of positive lymph node metastasis in group A was 7.1% (52/734), which was significantly higher than 22.1% (118/532) in group B (χ2 = 60.01, P < 0.05). The incidence of lymphatic micrometastasis was 9.4% (30/319) in group A, and 9.1% (23/252) in group B, with no statistical difference between the 2 groups (χ2= 0.01, P > 0.05). Conclusions Preoperative RIAC is helpful in improving the prognosis of patients with resectable pancreatic head carcinoma by reducing the incidence of lymphatic metastasis and decreasing tumor stage.

Objective To investigate the effect of amiloride pretreatment on the acute lung injury (ALI)induced by lipopolysaccharide (LPS) in rats. Methods Thirty-two pathogen-free male SD rats weighing 200-250 g were randomly divided into 4 groups (n = 8 each); group Ⅰ received iv normal saline (group C); group Ⅱ ALI received iv LPS 6 mg/kg (group ALI); group Ⅲ received iv amiloride 10 mg/kg (group A) and group Ⅳ received amiloride 10 mg/kg iv 30 min before iv LPS ( group AL). The animals were killed by exsanguination at 6 h after iv LPS infusion. The lungs were immediately removed. Microscopic examination of lung tissue was performed. The left lung was lavaged. The total protein (TP), TNF-α and macrophage inflammatory protein-2 (MIP-2)concentrations in broncho-alveolar lavage fluid (BALF) were measured. The W/D weight ratio and the myeloperoxidase (MPO) activity and expression of Na-H exchanger-1 ( NHE1 ), p38MAPK and extracellular signal-regulated kinase (ERK) in lung tissue were determined. Results LPS significantly increased ALI score (0 = slightest, 4 = severest), W/D lung weight ratio, TP, TNF-α and MIP-2 concentrations in BALF and MPO activity and the expression of NHE1, p38MAPK and ERK in the lung as compared with. control group. Amiloride pretreatment significantly attenuated LPS-induced changes except p38MAPK expression. Conclusion Pretreatment with amiloride can attenuate LPS-induced ALI by inhibition of ERK activation.

Objective To investigate the risk factors of ICU delirium in critically ill patients. Methods A total of 1 74 critically ill patients in ICU who were older than 18 yrs and stayed in ICU exceeding 24 hs from January 201 5 to June 201 5 were enrolled.Patients were divided into delirium group and non delirium group.Delirium was assessed twice daily with the Confusion Assessment Method for the ICU (CAM-ICU)during the first 7 days.The factors such as history of alcoholism and other 12 factors were analyzed by univariate and multivariate logistic regression analysis to identify those risk factors associated with delirium.Results With 22 cases of delirium in 1 74 patients,the in-cidence of delirium was 12.64% (delirium group).Variables associated with delirium were coronary heart history,operation,tracheal intubation,clinical use of mechanical ventilation,hypoxemia and Benzodiazepine.Multivariate logistic regression analysis showed that coronary heart disease (OR 3.932,95%CI 1.225-12.61 7),surgery(OR 9.691,95%CI 2.103-44.657),hypoxemia(OR 6.595, 95%CI 1.377-31.585),Benzodiazepine use (OR 7.620,95%CI 1.713-33.899)was independent risk factors of delirium in critically ill patients (P < 0.05 or P < 0.01 ).Conclusion Coronary heart disease,surgery,hypoxemia and Benzodiazepine are independent risk factors of ICU delirium in criti-cally ill patients.Early screening and prevention of delirium should be given to reduce the occurrence of delirium for patients in ICU.

Abstract?AlM: To compare the in- the- bag lOL stability of different size of continuous curvilinear capsulorhexis ( CCC) in super high myopic eyes with cataract underwent phacoemulsification.?METHODS: A total of fourteen cataract patients with bilateral super high myopia were included, Phaco+lOL implantation were performed on both eyes, one eye was randomly classified into 5mm diameter CCC observation group, the fellow eye was 6mm diameter CCC observation group. Cataract extraction combined with in-the-bag intraocular lens implantation ( lOL ) with the type of hydrophilic acrylic aspheric intraocular lens ( MCX11 ) by well experienced surgeon. The operation was running smoothly, the next day after operation, all patients were confirmed by lmage-pro plus6. 0 image analysis software for the measurement of main meridian sac diameter with target capsulorhexis diameter no more than ±0. 2mm. Slit lamp examination of lOL shape and position, changes of anterior capculorhexis edge, refraction, anterior chamber depth was measured and observed of all eyes after operation 1wk;1, 3, 6mo.? RESULTS: Compared with postoperation 1wk, the former sac diameter of two groups were slightly smaller at postoperation 1mo, with no statistically significant difference between two groups. 5mm diameter CCC observation group had slightly hyperopic shift in follow-up 1-3mo, 6mm diameter CCC observation group had hyperopic shift in follow-up 1mo, and getting stable after 1mo. Refraction change was related to anterior chamber depth changes. 5mm diameter CCC observation group had 3 minor loop folding in follw-up 3mo.?CONCLUSlON:Relatively smaller continuous curvilinear capsulorhexis in super high myopic eyes underwent cataract surgery may cause a tendency of uneven construction or effective lens position change of in-the-bag lOL. Unusual refraction change or shift after operation 1mo could suggest instability of lOL, early noticing or interruption could prevent further complications.
