Objective To investigate the value of serum proteomic profiling in cervical cancer detected pre-surgery and post-surgery. Methods Magnetic bead and matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) were used to detect the serum samples from 54 cases with cervical cancer before and after surgery and 53 serum samples from healthy women. The results of spectra were analyzed by Biomarker Wizard software. Results Significant variation of proteomic profiling between pre-surgery and post-surgery were analyzed. There were 22 proteins with different mass/charge (M/Z) values significantly different (P<0.01) at the M/Z value range from 1500 to 50 000, among of which relative content of proteins with M/Z 3981, 4290, and 28 066 in pre-surgery cervical cancer patients were higher than those in health women [(1.51±1.78)% vs (0.83±0.38)%, (2.70±2.19)% vs (1.72±0.91)%, (1.99±1.70)% vs (0.92±0.95)%; P<0.01], while in the post-surgery patients, relative content of these three proteins significantly decreased to (0.59±0.45)%, (1.01±0.64)%, (0.54±0.37)%, respectively. But the relative content of another three proteins with M/Z 11 487, 11 529, and 11 678 were significantly increased in post-surgery patients [(0.38±1.41)% vs (2.74±3.67)%, (0.16±0.46)% vs (2.00±1.76)%, (1.02±1.67)% vs (7.71±9.46)%; P<0.01]. Conclusion Serum proteomic profiling could screen out the proteins which had significant variation between pre-surgery and post-surgery serum, of which with M/Z 3981, 4290, and 28 066 may be related with tumor burden, while with M/Z 11 487, 11 529, and 11 678 may be response to surgical stress.

Objective To evaluate the characteristics of the CT perfusion for severe acute pancreatitis. Methods We performed CT perfusion scan on three groups of 9, 17and 41 cases with severe,mild and normal pancreatitis respectively, using 16 rows spiral CT, and got the perfusion data of the relevant groups including blood flow (BL), blood volume(BV), mean transit time( MTT), capillary permeability(PS)with perfusion package 3. We analize the data deviation between the groups mentioned above. Furthmore, we still adapt correlation test to compare the clinical biochemical indicators of MAP and SAP, with the variance BF. Results The mean values of BF, BV reduce significally in the groups of MAP, SAP compared to thenormal group(P＜0.01 ), only PS goes higher than that of the normal group(P＜0.05). At the same time,they are obviously higher in MAP group than in SAP group. In MAP group, the level of blood hemodiastase and BF are negatively correlated, on the contray, in SAP group, the level of the blood hemodiastase has no relation to BF. Conclusions CT perfusion techniques are of great significance in early diagnosis in SAP, and in guiding the clinical therapy.

Objective To investigate the value of pulse-indicate continuous cardiac output(PICCO) in septic shock patients.Methods In a retrospective study,58 patients who were diagnosed to be suffering from septic shock in the intensive care unit (ICU) were enrolled,from January 2010 to December 2011,and were divided into two groups:PICCO group(n =28) and the conventional group (n =30).We compared their 6 h-EGDT compliance rate,the level of lactate and central venous pressure (CVP),the oxygenation index,the characteristics of fluid intake and balance within 72 hours,duration of mechanical ventilation,and ICU stay of the two groups.The incidence of MODS after 72 hours in ICU,28-day mortality were recorded and compared.Results (1) Fluid intake((9565 ±1623) ml vs (12245±2253) ml,t=2.673,P=0.021) and balance ((3656 ± 1904) ml vs (5465 ± 2765) ml,t =2.357,P =0.012) were significantly lower in PICCO group compared the conventional group within 72 hours.(2) The oxygenation index ((252.6 ± 87.4) vs (226.8 ± 69.4),P ＜ 0.05) in PICCO group increased significantly and duration of mechanical ventilation ((134.7 ±42.8) h vs (193.3 ± 92.4) h,t =1.356,P =0.023) reduced significantly compared with the conventional group after 72 hours.(3) There was no difference in the 6 h-EGDT compliance rate,the level of lactate and CVP,6 h EGDT,ICU stay,the incidence rate of MODS after 72 hours,28-day mortality in ICU(P ＞0.05).Conclusion In contrast with classic methods as CVP monitoring,PICCO catheter may assess more accurately the volume status and guide early fluid resuscitation in septic shock patients.

Objective To evaluate the efficacy of port catheter system(PCS)placement in pulmonary artery via percutaneous subclavicle vein treatment for multiple metastatic tumor in the two lungs and discuss the PCS technique.Methods Fifteen multiple metastatic tumor patients(13 hepatocellular carcinomas,one mandible grand adenocarcinoma,one oral bottom squamous carcinoma)were carried out with pulmonary artery PCS placement by way of percutaneous subclavicle vein.FPA/FPM/GP chemotherapy scheme were introduced every 4～6 weeks.Results The success rate of PCS placement technique was 93.3%(14/15).One case failed.Percutaneous subclavicle veins were performed 14 cases in right side and 1 in left one.Following up 2～43 months,2～7 chemotherapy cycles(mean 5 cycles)were accomplished,and the clinical CR and PR were achieved in 1 and 3 cases respectively with clinical efficacy rate 28.6%(4/14).Major side reaction was late wound healing in 1 case.Conclusion PCS placement in pulmonary artery treatment for multiple metastatic tumor in the two lungs is effective,and mastering operation technique is the key for increasing operation suc- cess rate.

Background Recent studies have demonstrated that epicardial flow in nonculprit arteries,which has been assumed to be normal,was slowed in the setting of ST-elevation myocardial infarction (STEMI).However,the impact of primary percutaneous coronary intervention (PCI) on blood perfusion in nonculprit arteries in patients with STEMI has not been clarified.The purpose of this study was to investigate the impact of primary PCI on blood perfusion in nonculprit arteries in patients with STEMI and correlated clinical factors.Methods A total of 117 patients with anterior wall STEMI,the culprit artery being the left anterior descending artery (LAD),undergoing primary PCI (the study group) and 100 patients with normal coronary angiography (the control group) were enrolled.To observe the differences of corrected TIMI frame count (cTFC) and myocardial blush grade (MBG) before and after primary PCI in both culprit and nonculprit arteries,the left circumflex coronary artery (LCX),cTFC and MBG in the LAD and LCX were measured in the study group and control group.The study group was divided into three groups; reflow in the culprit artery group (the R group),no reflow in culprit artery group (the NR group),and no reflow in both the culprit artery and nonculprit artery group (the NRB group) according to MBG grade.The level of serum C-reactive protein (CRP),catecholamine,and fibroblast growth factor-21 (FGF21) were assayed.The clinical and angiographic characteristics were also analyzed.Results cTFC (28.1±24.3 vs.20.3±19.3,P ＜0.05) and MBG in the LCX were different in the study group compared to the control group before primary PCI.cTFC (25.2±22.3 vs.28.1±24.3,P ＜0.05) and the MBG level in the LCX were improved after successful primary PCI,but were not recovered to the normal level.Patients with no reflow in the culprit artery had a higher incidence of no-reflow in the nonculprit artery (78％ vs.19％,P ＜0.0001),and the levels of CRP ((3.29±1.31) mg/dl vs.(2.51±1.14) mg/dl vs.(2.93±1.07) mg/dl,P ＜0.05,respectively),catecholamine ((epinephrine (693.48±89.78) pg/ml vs.(398.12±93.28) pg/ml vs.(562.54±96.22) pg/ml,P ＜0.0001,respectively),and norepinephrine ((7012.43±932.47) pg/ml vs.(4012.34±814.16) pg/ml vs.(5549.03±912.65) pg/ml,P ＜0.0001,respectively)) in the NRB group were higher than those in the R group and NR group.The level of FGF21 ((0.299±0.093) ng/ml vs.(0.612±0.071)ng/ml vs.(0.428±0.074) ng/ml,P ＜0.0001 respectively) in the NRB group was lower than that in the R group and NR group.Conclusions The blood perfusion in the nonculprit artery may be impaired in patients with STEMI.Although nonculprit artery perfusion may be improved after successful primary PCI,it is still lower than that in the control group,and may be involved in inflammation and spasms.
