Objective To compare the impact of patient controlled epidural analgesia with patient controlled intravenous analgesia on postoperative recovery and complications in patients undergoing laparotomy pancreatic surgeries.Methods Forty patients undergoing pancreatic surgeries, 27 males and 13 females, aged 18-70 years, ASA physical status Ⅰ or Ⅱ, were randomly divided into two groups (n=20 each).Patients in group E received T8-9 or T9-10 epidural block, 2% lidocaine test dose was given to ensure the location of epidural catheter, after that, each patient in group E was given 0.375% ropivacaine 5 ml into epidural space before skin incising and incision closures.Meanwhile, patients in groups E and V received propofol-sevoflurane combined intravenous inhalation anesthesia.After surgery, patients in group E received patient controlled epidural analgesia while patients in group V received patient controlled vein analgesia.Length of hospital stay, time to ambulation and exhaust defecation were recorded.Other complications were compared.Results Compared to group V, patients in group E showed earlier ambulation [(50.4±4.2) h vs (64.2±5.0) h, P<0.01], shorter hospital stays [(18.5±8.5) d vs (21.5±6.8) d, P<0.05].There was no statistically significant difference in flatus time between the two groups [(39.7±4.1) h vs (39.5±8.4) h].There was no significant difference in complications between the two groups.Conclusion The present study shows that for patients undergoing pancreatic surgeries, patient controlled epidural analgesia could effectively release post-operative pain, shorten the ambulation time and length of hospital stay with no extra complications.

Objective To evaluate the risk of cardiovascular adverse events using nonsteroidal anti-inflammatory drugs during the perioperative period.Methods A systematic review of formally published in English and Chinese literature was conducted by using computerized database on PubMed, Web of Science, Medline, Cochrane Library, CNKI and Wanfang database.The literature about controlled clinical study of nonsteroidal anti-inflammatory drugs in perioperative use, a prospective cohort study and a retrospective review were collected.The cardiovascular risk was evaluated by the number of adverse cardiovascular events cases (myocardial infarction, angina, myocardial ischemia, arrhythmia) occurred during the period of drug use.The relevant data was extracted and their heterogeneity was tested.Results A total of 8 articles including 15 623 patients met the inclusion criteria, including 5 articles (n=13 019) on non-selective nonsteroidal anti-inflammatory drugs, and 3 articles (n=2 604) about selective (cyclooxygenase 2) COX-2 inhibitors.Nonsteroidal anti-inflammatory drugs used in the perioperative or a short term would reduce the risk of adverse cardiovascular events (OR=0.59, 95%CI 0.45-0.77, P=0.000 1), non-selective nonsteroidal anti-inflammatory drugs using in the perioperative or a short term would reduce the risk of adverse cardiovascular events, the difference being statistically significant (OR=0.42, 95%CI 0.31-0.58, P＜0.001).A selective COX-2 inhibitor using in the perioperative or short-term might increase cardiovascular adverse events (OR=2.53, 95%CI 1.26-5.09, P=0.009).Conclusion Non-selective nonsteroidal anti-inflammatory drugs should be chosen for patients at high risk of adverse cardiovascular events during the perioperative period.

Objective To investigate the Influence of FOXC1 downregulating on biological behavior of nasopharyngeal carcinoma (NPC) 5-8F cell lines. Methods Western blotting was used to detect the protein levels of FOXC1 in human immortalized nasopharyngeal cell lines NP69, nasopharyngeal carcinoma cell lines 6-10B with lower metastasis potential and nasopharyngeal carcinoma cell lines 5-8F with higher metastasis potential. siRNA was used to downregulate the expression of FOXC1 in 5-8F cell lines, and then ability of migration and invasion were observed. Results FOXC1 protein expression level in NP69 cell lines, 6-10B cell lines and 5-8F cell lines were (0.27 ± 0.04), (0.7 ± 20.06), (1.08 ± 0.05) respectively, and the difference was statistically significant (P < 0.05). Also ability of cell migration and invasion significantly weakened after FOXC1 depletion in 5-8F cell lines (P < 0.05). Conclusion FOXC1 might regulate invasion and metastasis of nasopharyngeal carcinoma through changing expression of Fibronectin and Vimentin, and FOXC1 may be an available target for molecular target therapy of nasopharyngeal carcinoma.

Objective To evaluate the clinical application value of active carbon nanoparticles to guide breast cancer tiny lymphadenectomy.Methods 50 patients with breast cancer were enrolled in the study and were divided into two groups by random number table.Active carbon particle was injected locally to guide the regional lymph nodes dissection in 25 cases as study group,and the traditional method was performed in 25 cases as observation group.Numbers of dissected lymph nodes were compared between two groups.Results The average number of eliminated small lymph nodes in the study group was dramatically more than that in the observation group[(23.60 ±4.61)vs. (14.60 ±5.16),t =3.47,P <0.05].There was significant difference between the study group and the observation group in the small ambulant lymph nodes[(5.80 ±1.49)vs.(2.89 ±1.66),t =2.91,P <0.05)].Conclusion Active carbon injected locally can eliminate not only more small lymph nodes,but also more small ambulant lymph nodes.

The particularities of oil suspension formulation can raise the invasive rate of Hirsutella sinensis to host of Hepialidae for the commercialization of artificial cultivation of Cordyceps sinensis. So it is important to develop a high cell viability oil suspension formulation of C. sinensis spawn. According to the characteristics of the oil suspension formulation, MTT assay is adapted and optimized.

Objective To detect the binding ability of the molecular probe of neuropilin-1( NRP-1) to mouse ectopic glioma by magnetic resonance imaging ( MRI) . Methods Glioma model mice were pre-pared by glioma tissue transplantation.Thirty tumor bearing mice were randomly selected for tissue anatomy(n=12) and other 18 mice were randomly divided into 3 groups:the control group ( group A) ,the probe con-trol group (group B) and the probe group (group C),which were given 20 μl saline,20 μl USPIO-PEG, 20μl USPIO-PEG-tLyP-1 through the tail vein of the mice respectively.And at 0h,6h,12h,24h after admin-istration,T2WI and T2MAPPING sequences were detected by MRI. Then the tumor bearing mice were killed immediately and the glioma tissue was used to detect the iron content by Prussian blue staining to detect the binding ability of the glioma tissue with the new molecular probe. The biological toxicity of the new molecular probe was detected by pathological staining. Results The expression of NRP-1 in glioma tissues was signifi-cantly higher than that in the liver,kidney and brain(P<0.05).The 24h relaxation time ((14.19±0.87)ms) of the glioma tissue in the C group was significantly lower than that in the B group ((25.94±0.77)ms) (P<0.05) ,and the blue staining particles in the C group were more than those in the B group(P<0.05) . Conclu-sion In the animal experiment,the molecular probe with NRP-1 as the target has obvious targeting effect and good biocompatibility,which provides a clinical basis of glioma for further clinical diagnosis.
