Objective To investigate the effect of stroke volume variability (SVV)-guided intraoperative fluid restriction on liver and renal function in patients undergoing hepatic lobectomy. Methods Forty ASA Ⅰ - Ⅲpatients of both sexes aged 33-60 yr weighing 52-80 kg undergoing elective hepatic lobectomy were randomly divided into 2 groups ( n = 20 each): group A routine fluid administration and group B restricted fluid administration.Anesthesia was induced with iv lidocaine, fentanyl and TCI of propofol (target plasma concentration 3-4 μg/ml).Tracheal intubation was facilitated with cisatracurium 0.2 mg/kg. The patients were mechanically ventilated.PETCO2 was maintained at 32-38 mm Hg. Anesthesia was maintained with 1%-2% sevoflurane inhalation and intermittent iv boluses of fentanyl and cisatracurium. BIS value was maintained at 40-60. Radial artery was cannulated and connected to continuous cardiac output monitor (Edwards Lifeaciences, USA). ECG, MAP, CVP and SVVtained at 5-7 in group A and 11-13 in group B. Blood loss, urine output and the amount of RBC and plasma infused during operation were recorded. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein (TP), albumin (ALB), total bilirubin ( TBIL), direct bilirubin ( DBIL), blood urea nitrogen (BUN), creatinine (Cr) and lactate and Hb, Hct were measured the day before surgery (baseline) and at day 1,3 and 5 after operation. Results The hemodynamic parameters were maintained within normal limits during operation in both groups. The blood loss, the amount of RBC and plasma infused and urine output during operation were significantly less, while the serum TP and ALB concentrations were higher on the 1st postoperative day in group B than in group A. The serum levels of ALT, AST, TBIL and DBIL were significantly increased and serum concentrations of TP and ALB and Hb,Hct decreased, but there was no significant change in serum BUN and Cr concentrations and lactate after operation as compared with the baseline values before operation in both groups. There were no significant differences in serum levels of ALT, AST, TBIL, DBIL, BUN, Cr, lactate,Hb and Hct after operation between the 2 groups. Conclusion SVV can guide effectively intraoperative fluid restriction in patients undergoing hepatic lobectomy.

Chinese herbal formulas can well present the characteristics of traditional Chinese medicine (TCM) with their simple, convenient, inexpensive and effective uses. However, due to the high cost of production, manufacturing pharmacies inside the hospital closed down one after another, which rendered the difficult situation of developing preparation of Chinese herbal formulas. The Pudong New Area of Shanghai, as a pilot region for comprehensive reforms on national development of TCM, vigorously explores the standardized research on and application of hospital-made Chinese herbal formulas. The Health Bureau of the Pudong New Area, based on the Shuguang Hospital, has established a clinical evaluation center for hospital-made Chinese herbal formulas. Through screening, manufacturing, quality control, unified allocation, and standardized clinical evaluation, the clinical evaluation center has summarized its experience on these processes.

Objective To clarify the role of pentraxin 3 (PTX3) in the development of peripheral arterial disease (PAD) in maintenance hemodialysis (MHD) patients. Methods One hundred and sixteen patients undergone MHD therapy in our center for more than 3 months were enrolled in the study. Clinical data were collected for analysis. Ankle-brachial index (ABI) was used to estimate the presence of PAD. Patients were divided into PAD group (ABI<0.9) and nonestimate the association of PAD with PTX3 as well as other potential risk factors. Results The incidence of PAD was 18.1% (21/116). Plasma level of PTX3 was significantly higher in PAD patients than that in non-PAD patients [(5.55 ±2.63) μg/L vs (2.32 ±1.29)μg/L, P<0.01].Univariate analysis showed ABI values were negatively correlated with plasma PTX3 levels (r =-0.548, P<0.01), high-sensitivity C-reactive protein (hsCRP), age, blood glucose and triglyceride. ROC curve of PAD revealed that area under curve (AUC) of PTX3 was 0.901 (P<0.01). With the cut-off value of PTX3 as 4.06 μg/L, the diagnostic sensitivity and specificity in PAD were 81.0% and 91.5%. ROC curve of PAD showed that AUC of hsCRP was 0.640 (P<0.05). With the cut-off value of hsCRP as 3.33 mg/L, the diagnostic sensitivity and specificity in PAD were 57.1% and 56.8%. Using Logistic regression, plasma PTX3 was found to be associated with PAD (0R=9.755, 95%CI:2.359-19.354, P=0.001). Conclusions The PAD incidence of MHD patients in our center is 18.1%. Plasma PTX3 level is significantly correlated with the presence of PAD in MHD patients. The sensitivity and specificity of PTX3 are higher than those of hsCRP for PAD diagnosis.

Objective To investigate the effect of high glucose on the expression of liver X receptors (LXRs) and ATP-binding cassette transporter A1 (ABCA1) in human macrophages (THP-1 cell line). Methods THP-1 monocytes were differentiated into macrophages by induction of phorbol 12, 13-dibutyrate (PMA). Surface markers of macrophages were identified by CD68 immunohistochemistry. The macrophages were cultured with different concentration (5.6, 11.1, 22.2 and 33.3 mmol/L) of glucose and different time (0, 0.5, 2, 6, 12, 24, 48, 72 h). Real time PCR and Western blotting methods were used to examine the mRNA and protein expression of LXRs and ABCA1. Results As compared to 5.6 mmol/L glucose, macrophage LXRβ and ABCA1 were decreased significantly at both mRNA and protein levels in dose-and time-dependent manner (P<0.05). Conclusion Hyperglycemia may play a role in the pathogenesis of arteriosclerosis through the inhibition of LXRs and ABCA1 expression in diabetic patients.

Objective:
To investigate the effects and related mechanism of bivalirudin on the survival of random skin flap on the back of rat.
Methods:
Thirty SD rats were divided into bivalirudin group and normal saline group according to the random number table, with 15 rats in each group. The random flap model with size of 9 cm×3 cm was reproduced on the back of rats in two groups. Immediately post injury, rats in bivalirudin group were intraperitoneally injected with 5 mg/mL bivalirudin (0.8 mL/kg), while rats in normal saline group were intraperitoneally injected with normal saline (0.8 mL/kg) once a day. The continuous injection lasted for 7 days. The flap was divided into distal area, middle area and proximal area averagely based on the flap blood supply. On post injury day (PID) 1, 3, and 7, the overall survival of each area of flap was observed with naked eyes. On PID 7, the survival rate of flap was calculated, and then the morphology of skin tissue at the center of the three areas of flap was observed by HE staining, the microvessel density (MVD) of the middle area of flap was calculated, and the expression of vascular endothelial growth factor (VEGF) of the middle area of flap was detected with immunohistochemical staining. Data were processed with
