Objective To evaluate the effect of LCVP applied during the operation of hepatectomy.Methods Sixty patients underwent hepatectomy were enrolled in the study from March 2010 to March 2012 in our hospital which were randomized into LCVP group and normal CVP (NCVP) group by the sealed envelope method. CVP was kept<0.5 kPa during entire procedure of hepatectomy in LCVP group, and the value of CVP and blood pressure were controlled within 10% of the baseline. The same anesthesia, incision and hepatectomy technique and indications of blood transfusion in LCVP group were undertaken as those in NCVP group. Intraoperative CVP, blood pressure, HR and blood routine were recorded. The time of operation, the amount of bleeding, the extent of removed hepatic tissue, the amount of transfused blood products,liver and renal function index, and coagulation function index were detected on the 1st, 3rd and 7th day after operation. Also the supplement of albumin, the rate of postoperation complications and the length of hospital stay and the expense in hospital were recorded.Results ① The general clinical data of patients were similar in the two group (P>0.05). ② The operation time, total bleeding volume, bleeding volume and RBC infusion volume in LCVP group were significantly lower than those in group NCVP (P<0.05). ③ There were no significant difference of postoperative liver and renal function index between the two groups (P>0.05). But the supplement of albumin in LCVP group after operation was significant less than that in NCVP group (P<0.05). ④ There were no significant difference of the postoperative complication, the length of hospital stay and the expense in hospital between the two groups (P>0.05).Conclusions The application of LCVP in hepatectomy cause less blood loss, shorten the length of hospital stay and decrease the expense in hospital, which is beneficial for the postoperative recovery.

Objective By discussing the accuracy of A-scan and IOL Master in intraocular lens power measurement, to offer Objective clinical data for cataract surgery.Methods Three hundred patients(300 eyes)with age-related cataract were included in the study. Before surgery,axial length was measured by A-scan and IOL Master respectively and corneal curvature was measured by auto refractometer. A-scan group used the corneal curvature data of the auto refractometer. IOL Master group used the corneal curvature data from the instrument. Intraocular lens power was calculated according to the SRK-T formula.We observed the refractive state of 3m after operation, detected and analyzed the patient's refractive data by the auto refractometer.Results All patients who were included in the study were randomly divided into A-scan group and IOL Master group.The mean axial length was (23.21±0.59) mm measured by A-scan, the mean axial length was (23.22±0.59) mm measured by IOL Master. There was no significant difference between them (P>0.05). The preoperative mean corneal curvature measured by the auto refractometer was (44.01±1.79)D. The preoperative mean corneal curvature measured by IOL Master was (44.13±1.62)D. There was no statistically significant difference between them (P＞0.05). The mean absolute refractive error ( MAE) in A－scan group was (0.43±0.26)D and in IOL Master group was (0.42±0.17)D. There was no statistically significant difference between them (P＞0. 05).Conclusion IOL Master group operated slightly better than A-scan group, but we did not find a significant advantage in intraocular lens power measurement with A-scan group. IOL Master may not completely replace A-scan. The combination of the two ensures the accuracy of the measurement in intraocular lens power.

Objective Few studies has been conducted concerned Glomerular Filtration Rate(GFR) estimationequations about Cockcroft-Gault equation(CG equation)and Chinese Modification of Diet in Renal Disease equation(c-MDRD equation)in systemic lupus erythematosus(SLE). Our study aims to assess performance of two equations for renal function evaluation in patients with SLE.Methods 193 participants were enrolled in this study. Measured GFR was obtained by renal dynamic imaging method and Serum Creatinine (SCr)was determined for each participant. eGFR was gained by CG equation and c-MDRD equation respectively. Performance of equations were compared from different aspects.Results mGFR(median), eGFR-CG(median), eGFR-cMDRD(median)of the 193 participants were 75.01,70.22,70.67 mL/(min·1.73 m²)respectively. The participants were divided into two groups including mGFR≥60 (n=108)as well as mGFR<60 mL/(min·1.73 m²)(n=85). For overall participants, bias for CG equation and c-MDRD equation were 0.64, 3.91 mL/(min·1.73 m²) respectively. In terms of precision and accuracy, CG equation was better than c-MDRD equation. In subgroup, CG equation was still superior to c-MDRD equation except for bias in CG equation which is higher than c-MDRD equation in mGFR<60 ml(min·1.73 m²).Conclusion Compared with c-MDRD equation, CG performed better in GFR estimation in patients with SLE.

Objective To investigate the effects of alprostadil combined with epalrestat on the expression of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) in granulation tissue in patients with diabetic foot patients.Methods Totally 90 cases with diabetic foot were randomly divided into study group (45 cases)and control group(45 cases). The control group received conventional treatment for 4 weeks and the study group additionally received combination of alprostadil and epalatone for 4 weeks. The curative rate of wound healing, limb dorsal hemodynamics, peroneal nerve conduction velocity and the levels of TNF-α, IL-6 and VEGF in the granulation tissue of the wound were monitored in the two groups.Results The wound healing rate of the study group was significantly higher than that of the control group at the 2nd and 4th week after treatment (P<0.05). After treatment, the hemodynamics and peroneal nerve conduction velocity were improved (P<0.05). The contents and expressions of TNF-α and IL-6 in the granulation tissue of the treatment group were significantly lower than that of the control group, and the content of VEGF and gene expression were significantly increased in the study group (P<0.05).Conclusion The combination therapy of alprostadil and epalrestat may improve the hemodynamics of dorsalis pedis artery in patients with diabetic foot and promote the recovery of damaged nerve function.Also it may reduce the expression of TNF-α and IL-6 in the granulation tissue of diabetic patients and reduce the immune injury. It promotes angiogenesis and accelerates wound healing by increasing VEGF gene expression.
