Forty-eight patients with subclinical Cushing's syndrome(SCS)were evaluated.Eleven of them underwent adrenalectomy(Group 1)and the other 37 cases did not(Group 2).Serum and urine corticosol, plasma ACTH and parameters related to metabolic syndrome(such as waist circumference,blood pressure,blood lipids and fasting plasma glucose)were measured.The data at diagnosis were compared with those during the survey.The results indicated that patients with SCS had a significantly high prevalence of metabolic syndrome.The symptoms and signs of metabolic syndrome could be improved after removing the tumor.Otherwise there is no improvement,some patients will even develop into overt Cushing's syndrome.

Objective To investigate pulmonary infect flora distribution characteristics of stroke patients with tracheotomy in Intensive care unit (ICU) and analyze the risk factors.Methods A total of 792 cases of ICU stroke patients was selected,including 426 cases of tracheotomy patients,and 366 cases of non-tracheotomy patients.The incidence of lung infections was compared.Bacteriological examination was used for tracheotomy bacteriological studies for lung infected stroke patients with tracheotomy.Bacteria infection's characteristics was observed.The risk factors were analyzed.Results (1) The tracheotomy patient 's lung infection rate was 23.00％,higher than 9.56％ of the non-tracheotomy patients,the difference was statistically significant (X2 =19.125,P ＜0.05);(2) For lung infection-occurred patients with tracheotomy of ICU,gram-negative bacteria infection rate was 63.97％,significantly higher than 19.85％ of gram-positive bacteria and 16.18％ of fungi,the difference was statistically significant (x2 =18.255,17.042,P ＜ 0.01);(3) Lung infection rate of ICU stroke tracheotomy patients with unconscious,dysphagia,hospitalization time ＞ 14 d,blood glucose levels ≥≥7.8 mmol/L,and based diseases was significantly higher than that of patients with conscious,non-dysphagia,hospitalization time ≤＜14 d,blood sugar level ＜7.8 mmol/L,and no based diseases (P ＜ 0.05);(4) Consciousness,dysphagia,hospitalization,blood sugar levels,and the underlying disease were the independent risk factors of lung infection in ICU stroke tracheotomy patients (OR1 =11.528,OR2 =8.046,OR3 =15.174,OR4 =7.795,ORs =10.784,P ＜0.05).Conclusions Gram-negative bacteria is the main reason for pulmonary infections in ICU stroke tracheotomypatients patients with stroke.State of consciousness,invasive treatment,hospitalization,blood sugar levels,and the underlying disease are the independent risk factors.

Objective To observe the effect of Ti-6AL-4V particles on morphological and func- tional changes of osteoclast in vitro.Methods Mature osteoclasts separated from New Zealand Rabbits were cultured on glass slices and cortical bone slices.The experimental group was stimulated by Ti-6AL- 4V particles at concentration of 0.1 mg/ml.The cells were stained with TRAP at different culture time to observe the morphological variety.The bone resorption pits on bone slices were stained by toluidine blue and the resorption areas analyzed by computer image analysis software.Results Osteoclasts phagocy- tosed the particles,with irregular shapes,deeper TRAP stain and earlier apoptosis.Stimulation by Ti- 6AL-4V particles brought about larger area of bone absorption lacuna.Conclusion Osteoclasts have the ability to phagocytose Ti-6AL-4V particles,which leads to morphological and functional changes and enhances bone resorption.

This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.

OBJECTIVETo investigate the levels of lipopolysaccharide binding protein (LBP) in serum and ascites of cirrhotic patients, and determine their diagnostic value for spontaneous bacterial peritonitis (SBP).

METHODSCirrhotic patients were divided into groups according to diagnosis of SBP, ascites without SBP, no ascites. To explore the significance of LBP in clinically suspect SBP cases, the ascites without SBP group was sub-divided into two groups according to the symptoms of abdominal pain or elevated white blood cell (WBC) count, and abdominal pain combined with elevated WBC count. Two control groups were composed of patients with intraperitoneal pus and a group of healthy, non-cirrhotic individuals. The LBP levels in serum and ascites were determined by enzyme-linked immunosorbent assay (ELISA). The ascites routine, ascites culture and albumin assay were carried out in the Second Affiliated Hospital of Chongqing Medical University. Data between the two groups were compared using the t-test or nonparametric test of independent samples, and the areas under the curve were compared using the Z test. Results The levels of LBP in serum and pus were significantly higher in the intraperitoneal pus group than in the cirrhosis group with ascites (P less than 0.01).

RESULTSThe level of serum LBP was significantly higher in the cirrhosis group with SBP than in the cirrhosis group without SBP but with ascites and the cirrhosis group with no ascites (P less than 0.01). There was no significant difference in the level of ascites LBP in the cirrhosis group with SBP and the cirrhosis group without SBP but with ascites (P more than 0.05). In the clinically suspect cases with SBP, the levels of LBP in serum and ascites were significantly higher than those in the cirrhosis group without SBP but with ascites (228.00 mug/ml vs. 80.95 mug/ml and 22.50 mug/ml vs. 11.45 mug/ml, P less than 0.05). Determination of serum LBP had a higher sensitivity than the determination of ascites LBP or ascites WBC.

CONCLUSIONGram-negative bacteria infection in the intra-abdominal cavity causes serum and body fluid levels of LBP to increase significantly. Patients with cirrhosis complicated with SBP have significantly elevated levels of serum LBP. The serum and ascites LBP levels are significantly elevated in SBP patients with suspected clinical diagnosis. Measurements of both the serum LBP and ascites LBP may have diagnostic value for SBP.

Human tissue kallikrein-binding protein (Kallistatin, KAL), a secretory protein that participates in the regulation of multiple signaling pathways by binding to the extracellular receptor, however, at present has not been reported about the intracellular activity, and whether it has the similar biological activity with extracellular activity. Here we constructed no signal peptide KAL (NSK) into the adeno-associated virus vector to explore the intracellular activity of KAL. Both the endothelial cell and lung cancer cells could express KAL, but not secreted after rAAV2-NSK transfection. The proliferation and migration of human umbilical vein endothelial cells (HUVECs) were inhibited, but the apoptosis rate was not affected. The proliferation rates, mobility and tubule formation of all the three tested lung cancer cells, such as NCI-H446, NCI-H460 and A549, were inhibited to different extents. This cellular study not only confirmed the intracellular activity, but also suggested it may serve as a kind of "balance factor" in multi-targeted controlling, which may provide a new train of thoughts to explain the regulatory contradiction in PI3K-Akt signaling pathways by KAL.
