Objective The incidence rate of complication during central venous catheterization through internal jugular vein (IJV) and subclavian vein (SV) puncture. Methods Clinical controlled trials about IJV and SV puncture were collected and related literatures were screened according to the criteria of inclusion. The literatures underwent Meta analysis and subsequent analysis of sensitivity. Results A total of 18 literatures were included. Meta analysis indicated that statistical difference existed in the related infection rate [RR=1.74, 95%CI (1.32, 2.30)] and arterial puncture [RR=3.19, 95%CI (1.70, 5.99)], but not in the one-time-puncture success rate [RR=1.06, 95%CI (0.90, 1.24)] between IJV and SV puncture. Conclusions The rate of related infection and arterial puncture was higher by IJV than by SV puncture. But we could not confirm if any difference existed in the one-time-puncture success rate between the two methods. The results still needs evaluation by high-quality randomly controlled experiments.

Objective To find the liver cancer specific peptide for serological screen of liver cancer patients via screening phage-display peptide library. Methods Fifteen sera from liver cancer patients and physical examinates were collected for the four-round screening with Ph. D. 12TM phage display peptide kit. Highly specific phage monoclones were selected based on the ELISA results of the serological assay. The peptide labeled with FITC was synthesized according to the DNA sequencing of the optimal monoclone and tested with serum via fluorescent imagery. Results Nine highly specific monoclones were found among 50 selected ones after 4 rounds of screenings. The positive rate of the optimal monoclone,ZH-3, reached 46.7 %. The peptide sequence of ZH-3 was concluded by DNA sequencing as SAHGTSTGVPWP. Desirable specificity and affinity were also shown in the serum of liver cancer patients. Conclusion The peptide ZH-3 can be used as a diagnostic reagent for liver cancer.

Objective To eompare the dose distribution of three-dimension conformal radiation therapy(3DCRT) and common radiation therapy (CRT) of the planning target volume(PTV) and organ at risk (OAR) in recurred cervical cancer treatment planning. Methods Thirteen patients,who had cervical cancer recurred in pelvis treated with 3DCRT in Shanxi Cancer Hospital from May to August 2007, were selected. After CT simulation, the CT images were transferred into Topslane treatment system. The same physicist designed 3DCRT plan and common radiation therapy plan for every patient,total dose 50 Gy, 90 % is dose covered PTV, then compared the dose distribution of PTV and OAR.Results At the same prescribed dose of 50Gy,there were no significant differences on OAR maximum dose between 3DCRT plans and common radiation therapy plans(P >0.05), however, there was significant differences on PTV maximum dose(P <0.01). The difference of PTV uniformity were significant between 3DCRT plans and common radiation therapy plans (P <0.001). Compared the high dose region of OAR(V40), the difference was significant (P <0.001). Between 3DCRT plans and common radiation therapy plans, they showed 53.31 ml (90.69 %), 124.00 ml (79.47 %), 655.16 m1(92.22 %) median reduction in the V40 of rectum, bladder, intestine, respectively. Conclusion At the same PTV coverage of the prescribed dose, 3DCRT plans showed worse dose uniformity, however, the radiation volume to organs at risk in 3DCRT plans were smaller than common radiation therapy plans. So patients with cervical cancer recurred in pelvis received 3DCRT may be potentially diminish the Normal Tissue Complications Probability(NTCP).

Objective To study the CT and MR characteristic features of the respiratory epithelial adenomatoid hamartoma of olfactory clefts. Methods (1)The CT and MRI findings of 29 patients with histologically proved respiratory epithelial adenomatoid hamartoma in the olfactory clefts were retrospectively reviewed.All patients underwent CT and 8 of them underwent MRI. Location, CT and MRI features, and associated findings of the disease were reviewed;(2)The CT findings, olfactory clefts width, total nasal distance, and the ratio of OC to the total nasal distance of the case patients (29 cases) and the control patients (33 patients with sinusitis) were compared to investigate the correlation of the olfactory clefts distance and the incidence of respiratory epithelial adenomatoid hamartoma in olfactory clefts. Results All patients were associated with sinusitis, and 23 had sinonasal polyps, 1 had papilloma. On nonenhanced CT, the OC lesions with the OC widening were isodense to gray matter in all cases, and the lesions caused the adjacent bony expansion and absorption rather than erosion; 15 cases were bilateral diseases and 14 were unilateral;The olfactory clefts width of the case patients and the control patients were (1.03±0.24) cm, (0.71± 0.17) cm, respectively. There was statistically significant difference (t=4.963, P<0.01) for the olfactory clefts width between the case patients and the control patients, and there was no significant difference (t=1.640, P>0.05) for the total nasal distance, and was significant difference(t=6.029,P<0.01)in the ratio of OC to the total nasal distance between the two groups. On T1WI, the disease appeared isointense in 6 patients and slightly hypointense in 2 patients compared with gray matter. On T2WI, the lesions revealed heterogeneous isointense in all patients. Regular cribriform pattern was found on MR T2WI and enhanced TlWI. Conclusions The unilateral or bilateral olfactory cleft opacification in chronic sinusitis patients with or without sinonasal polyposis, with involved OC widening and the adjacent bony walls compressed and remodeled may highly suggests the presence of REAH in the OC. The lesions showed inhomogeneous isointense signal on T2WI images, regular cribriform pattern enhancement are typical imaging feature of this entity.

Objective To investigate the various occasions of invasive mechanical ventilation in patients with acute left heart failure. Methods Thirty-two patients with acute severe left heart failure were divided into two groups:17 patients were treated with non-invasive mechanical ventilation (non-invasive mechanical ventilation group) and 15 patients were treated with invasive mechanical ventilation (invasive mechanical ventilation group). The respiratory rate (RR), arterial oxy-gen partial pressure p(O2), heart rate (HR) and mean arterial pressure (MAP) were observed after treatment for 0.5 h,1 h and 3 h in two groups of patients. The in-hospital mortality was compared between two groups. Results Ten patients of non-in-vasive mechanical ventilation group were in remission after 0.5 h, 7 cases without remission switched to endotracheal intuba-tion for invasive mechanical. And 3 of them were in remission in 0.5~1 h, 4 of them dead. Fourteen patients in invasive me-chanical ventilation group were in remission after 0.5 h, one case was in remission after 0.5~1 h and no dead in this group. There were more patients in remission after 0.5 h in invasive mechanical ventilation group than those of non-invasive me-chanical ventilation group (P=0.041). There were no significant differences in the number of patients in clinical remission af-ter 0.5~1 h and mortality between two groups. The values of RR and HR were decreased with the increasing treatment time in two groups. The values of p(O2) and MAP were increased with the increasing treatment time in two groups. There was a sig-nificantly lower RR at 0.5 h and 1 h in invasive mechanical ventilation group than that of non-invasive mechanical ventila-tion group (P < 0.05). The values of p(O2) and MAP were significantly higher at 0.5 h in invasive mechanical ventilation group than those of non-invasive mechanical ventilation group (P<0.05). The levels of HR at 0.5 h and 3 h were significant-ly lower in invasive mechanical ventilation group than those of non-invasive mechanical ventilation group ( P<0.05). Con-clusion Invasive mechanical ventilation should be used as soon as possible if non-invasive mechanical ventilation can not alleviate the symptoms in patients more than 0.5 hours.
