Objective To look for a better way to assay vascular endothelial growth factor(VEGF) and explore the correlation of serum VEGF levels with platelet and leucocyte count in breast cancer by comparison of peripheral blood plasma, serum and P-APR. Methods Blood samples were obtained from 42 patients with breast cancer and 20 healthy volunteers. Serum, plasma and P-APR samples were analyzed for VEGF using a commercially available sandwich ELISA, and assayed for semiquantitative measurement using microplatereader. At the same time, samples were analyzed by hematology analyzer. Results The level of VEGF in peripheral blood positively correlated to platelet (health control group: r=0.424, P=0.063) and leucocyte (health control group: r=0.443, P=0.050). The difference in VEGF values of P-APR between the localized breast cancer group and the health control group was statistically significant. Conclusion The level of VEGF in peripheral blood positively correlates to platelet and leucocyte. Platelet and leucocyte possibly secrete VEGF in vitro. Compared with serum and plasma, P-APR is the best section assaying VEGF in peripheral blood.

ObjectiveTo investigate the significance of clinical feature in the source localization of epileptogenic zone in children with frontal lobe epilepsy.MethodsThirty children who were diagnosed frontal lobe epilepsy consecutively admitted to the pediatric department of Shengjing hospital from Oct 2010 to Jun 2011 were recruited for retrospective study.All the cases were subject to video-electroencephalogram monitoring.Results Seventy-six episodes with clear origins of the electroencephalogram were monitored in 30 cases,including orbital frontal attack 11 times (14.5％),dorsolateral frontal attack 33 times (43.4％),mesial frontal attack 32 times (42.1％ ).The correlation analysis showed that the head and eye deviation (47 times,61.8％ ),asymmetric tonic seizures (32 times,42.1％ ) and parakinesia seizures (29 times,38.2％ ) prompted the focus was located in the dorsolateral frontal and mesial frontal.But there was no significant difference between the two areas ( x2 =10.58,9.67,11.55,P ＞0.05).The vocalization,manual pedal automatism and emotional seizure prompted the focus was located in the dorsolateral frontal and orbitofrontal;and the emotional seizure was significant differences between the two areas(x2 =38.68,P ＜0.001 ).Emotional seizure was the characteristic of orbitofrontal attack.Conclusion The clinical features have important significance in the judgment of the source localization of epileptogenic zone in children with frontal lobe epilepsy.The emotional seizure could be considered as the characteristic attack of orbitofrontal.

Objective To investigate surgical techniques of minimally invasive management for multiple calculi in the kidney and ureter. Methods Combined use of ureteroscopic lithotripsy(URSL) and minimally invasive percutaneous nephrolithotomy(MPCNL) was carried out in 21 patients with multiple calculi in homolateral kidney and ureter between January and October 2005 in this hospital.Results Percutaneous nephrostomy was required before the stone removal in 2 patients with pyonephrosis.Of the remaining 19 patients,all the ureteral calculi were completely removed on one session.And the renal calculi were removed by single session in 13 patients,by secondary percutaneous nephrolithotomy in 3 patients,and by tertiary nephrolithotomy in 2 patients.The combination treatment failed in 1 patient because of stricture of uretero-vesical orifice and a conversion to open surgery was needed.Conclusions Combination use of ureteroscopic lithotripsy and minimally invasive percutaneous nephrolithotomy is effective for the treatment of multiple calculi in homolateral kidney and ureter,offering advantages of minimal invasion,rapid recovery,and few complications.

Objective To compare the surgical outcomes between laparoscopic and open surgeries in treatment of ectopic oviduct pregnancy, and investigate the clinical value of laparoscopic surgery. Methods Two hundred and forty-six patients with ectopic oviduct pregnancy in our hospital from June 2009 to March 2013 were retrospectively analyzed. 134 cases were treated with laparoscopic operation and 112 with open surgery. Some parameters such as operative time, blood loss, usage of pain-killer, hospital stay were compared between both groups. Results All operations were successful. Laparoscopic surgery was shown to be superior to open operation in the parameters of operative time, blood loss, usage of pain-killer and hospital stay ( < 0.05) . Conclusion Compared with open operation, laparoscopic surgery has the advantages of less trauma and rapid postoperative rehabilitation. It may become the first line treatment for ectopic oviduct pregnancy.

Aim To study the application status of odds ratio for medical animal experiments.Methods Odds ratio and seven kinds of animal models were used as retrieval strategy to search medical animal experiment related papers in several Chinese and English databases.Papers relating to each kind of animal model and using odds ratio in abstract and text were counted. Data from different databases were compared. Calculation of odds ratio was exemplified and the significance of different odds ratio values was illustrated in this paper.Results Few medical animal experiments cited odds ratio as statistics.Conclusions The importance of odds ratio has not been fully recognized in Chinese references.

Objective To study the proper desiccation and the expiry date for humidifier after disinfection, and then decline the incidence rate of infection in hospital. Methods Divided 84 humidifiers into the A and B groups randomly after disinfection, there were 42 humidifiers in the each group. The natural desiccation was used in the A group, the oxygen desiccation was used in the B group. Monitored the humidifiers of the two groups respectively lasted 7 days, and then compare the datum between them. Results The expiry date of the humidifiers which have dried by natural desiccation was longer than that of humidifiers which have dried by oxygen desiccation. Conclusion We should set down the expiry date for humidifier according to the different desiccation and the different seasons.

Objective To investigate the effects of serum from patients receiving isoflurane and sevoflurane on the invasion and migration ability of human lung adenocarcinoma cell line A549. Methods Twenty ASAⅠorⅡ lung cancer patients aged 40 ~ 68 yr undergoing radical surgery were randomly divided into sevoflurane group (SEV group, n = 10) and isoflurane group (ISO group, n = 10). The concentration of sevoflurane or isoflurane maintained 1.5 MAC during anesthesia. Ten healthy volunteers were selected as control group. Serum was separated from blood sample taken at the end of surgery. A549 cells were randomly divided into sevoflurane group (group SEV, n = 10), isoflurane group (group ISO, n = 10) and control group (group C, n = 10). Cells of SEV group and ISO group were treated with 10% serum as respect to anesthetics for 24 hours. Cells of group C were treated with serum of control group. The invasion ability of cells was evaluated by Transwell assay. The migration ability of cells was determined by wound healing assay. The expressions of MMP-2 and MMP-9 in A549 cells were detected by ELISA. Results Compared with group C and ISO group,the number of invasive cells in group SEV was reduced significantly (P < 0.05). The levels of MMP-2 and MMP-9 in group SEV were significantly decreased compared with those of group C and ISO group (P<0.05). Conclusion The serum of patients receiving sevoflurane anesthesia can attenuate the metastatic ability of A549 cells through inhibiting the expression of MMP-2 and MMP-9.

Objective To observe the effect of midazolam plus propofol administered for colonoscopy on cognitive function in middle-aged and aged patients. Methods One hundred and thirty six patients, ASA I and II, aged 40~75 years and undergoing colonoscopy were randomized to propofol group (group P, n=68) and propofol plus midazolam group (group PM, n=68). Baseline cognitive function was measured using Mini mental state exami-nation (MMSE) before anesthesia and the cognitive testing was repeated 10 minutes after emerging from anesthesia. BP, HR, SpO2, analgesic effect and sedative drug doses in both groups were recorded. Procedure time, recovery time and Rasmay sedation score were both recorded. Results Recovery time was significantly longer in group PM than that in group P (P<0.05). The total dose of propofol was significantly smaller in group PM than that in group P (P<0.05). MMSE score of both groups decreased, but the incidence of cognitive decline and the level of cognition in group PM were more notable than those of group P (P<0.05). Conclusions Midazolam plus propofol and propo-fol alone administered for colonoscopy could both increase the incidence of cognitive decline, and the effect of the former is more notable, but midazolam added to propofol could reduce the dosage of propofol.

Diabetic retinopathy is a major cause of blindness all over the world, and it is one of the most serious and common microvascular complications of diabetes. Breakdown of the endothelial blood - retinal barrier ( BRB ) , as occurs in diabetic retinopathy, result in vasogenic edema and neural tissue damage, causing loss of vision. The inner BRB is created by complex tight juctions of retinal capillary endothelial cells, this barrier prevents the free diffusion of substances between the circulating blood and the neural retinal, the inner BRB efficiently supplies nutrients to the retinal and removes endobiotics and xenobiotics from the retina to maintain a constant milieu in the neural retina. The central mechanism of altered inner BRB function is a change in the permeability characteristics of retinal endothelial cells caused by elevated levels of cytokines, growth factors, advanced glycation end products, inflammation, hyperglycema and loss of pericytes. This article reviews the relationship between diabetes and the ultrastructure changes of BRB.
