Objective To investgate the application of overall hemostasis potential (OHP) experiment in the high-risk population of prethrombotic state (PTS). Methods The change of absorbance in fibrin formation and degradation was measured with a spectrophotometer at 340 nm when the plasma clotting was triggered by the low concentration of TF in the presence of urokinase. The OHP,overall coagulation potential (OCP) and the overall fibrinolysis potential (OFP) were obtained from the coagulation-fibrinolysis curve based on the computer analysis. To evaluate this OHP method,52 cancer patients,31 coronary artery disease patients,27 mid/late-stage pregnancy women and 100 healthy controls were detected. In addition,the plasma fibrinogen was detected and its correlation with OHP was studied. Results The level of OCP and OHP in PTS high-risk population was significantly higher in cancer,coronary heart disease patients and the mid/late-stage pregnancy women than in the healthy controls (P0.05). Conclusion The OHP assay may indicate the hemostatic balance; therefore,it can be used for evaluation of PTS.

Objective To explore the influence on isthmic spondylolisthesis (IS) from lumbar vertebras facet joint orientation (FJO) variation. Methods The lumbar vertebras of 60 patients scanned by 16-slices spiral CT were collected, 30 cases with IS was defined as isthmic group;30 cases with normal lumbar vertebras was defined as control group, the FJO at L3-4, L4-5 and L5-S1 were measured in two groups. The difference between two groups were compared at three levels, the difference between both sides of the facet joint orientation also was compared;the measured data and the data of 60 patients from foreign literature were compared at three levels. Results The FJO in isthmic group were (47.9±6.3)° ,(37.5±7.3)° , (37.9±7.7)° at the right of L3-4, L4-5, L5-S1 levels respectively,the FJO in control group were (53.1 ± 7.3)° , (40.5±6.3)° , (38.5±7.3)° respectively, the FJO in isthmic group were (48.1±6.0)° , (37.9 ± 7.4)° , (37.6 ± 7.6)° at the left of L3-4, L4-5, L5-S1 levels respectively, the FJO in control group were (52.3 ± 7.6)° , (41.6 ± 6.0)° , (38.2 ± 7.2)° respectively. The significant difference was found at L3-4 and L4-5 levels (P < 0.05), the orientation was similar at L5-S1 level (P > 0.05). The difference between the both sides FJO of lumbar vertebras was not found at L3-4,L4-5 and L5-S1 levels (P >0.05). The same as the measured data and the corresponding data from foreign literature(P > 0.05 ). Conclusions It seems possible that the coronal FJO may be the phenotypic representation of the familial etiology of IS. It is helpful for the measurement of lumbar vertebras FJO to find IS early,it is important to reduce and release the IS.

Objective To explore the relationship between ERG4 gene overexpression and azole resistance in clinical Candida albicans strains. Methods The National Committee for Clinical Laboratory Standards (NCCLS)M27-A2 broth microdilution method was conducted to evaluate antifungal susceptibility of 34 clinical Candida albicans isolates in vitro. Total RNA was extracted from these Candida albicans strains and transcribed into cDNA. Real-time fluorescence-based quantitative PCR was performed to determine the mRNA expression of ERG4 gene. Statistical analysis was carried out by a two-sample t-test. Results The expression level of ERG4 mRNA was significantly higher in fluconazole-resistant than in -sensitive Candida albicans strains (4.20 ± 2.56 vs. 1.72 ± 1.33, t = 3.99, P < 0.05), higher in itraconazole-resistant than in -sensitive Candida albicans strains (3.60 ± 2.47 vs. 1.66 ± 1.61, t = 3.71, P < 0.05), and higher in voriconazole-resistant than in -sensitive Candida albicans strains (3.99 ± 2.72 vs. 2.07 ± 1.58, t = 2.91, P <0.05). Further more, increased ERG4 mRNA expression was also observed in isolates cross-resistant to all the three azole antifungal agents compared with those susceptible to all of them (4.49 ± 2.73 vs. 1.69 ± 1.82, t = 3.81, P < 0.05). Conclusions The overexpression of ERG4 gene may be associated with cross resistance to fluconazole, itraconazole and voriconazole in clinical Candida albicans strains, but its exact role is expected to be investigated through downregulation of the ERG4 gene.

Objective To compare the traumatic indicators of complete video-assisted thoracoscopic surgery (c-VATS) with traditional open surgery (TOS) for lung cancer patients, and further explore the minimal invasiveness of c-VATS. Methods From January 2010 to February 2013, 45 cases with complete video-assisted thoracoscopic surgery (c-VATS gurop) and 42 cases with traditional open surgery (TOS group) were compared in operation time, intraoperative blood loss, duration of chest drainage, the perioperative cytokine and immune cells (CRP,WBC,N,L),pain score and shoulder function score. Results There was no significant difference between groups in sex, age, pathological type, stage,operating time and the perioperative cytokine and immune cells (CRP, WBC, N, L) ( >0.05);Compared with TOS group, c-VATS group intraoperative blood loss was significantly reduced [(167.4±68.5) mL vs (288.6±84.0) mL, =0.000];Drainage time of TOS group was significantly longer than that of c-VATS group [(4.64±2.10) days vs (3.20±1.20) days, =0.000];The postoperative pain measurements in c-VATS group were less than that in TOS group, but the difference between groups was not significant on postoperative 1 day ( =0.542) and significant on postoperative 3 day,7 day,30 day ( = 0.034, 0.000, 0.000) . Patients activities of daily living scores at postoperative 7 day and 30 day in c-VATS group were significantly better than those in TOS group, with statistically significant differences ( =0.000,0.000) . Conclusion Whether the short-term effect or the long-term results,the VATS lung resection is better than the traditional open surgery. c-VATS resection of lung cancer is more invasive.

Objective To study the feasibility, safety and clinical application value of LRH, comparing with abdominal radical hysterectomy (ARH) . Methods A total of 80 patients' clinical data were collected to analyze the development of LRH in Yunnan Tumor Hospital while compared with another 40 patients between June 2012 to June 2013 of ARH for some associative indexes. Results The patients were divided into group A and B equally.Compared with Grope A, the time of operation decreased 26.9%, 37.2% has been augment for lymph gland sweeping, the amount of bleeding and intraoperative complication reduced 37.3% and 7.5% in Grope D, respectively, with distinctive difference ( >0.05) .Hospitalization expenses had a small degree reduced but no distinctive difference.The learning curve of LRH was 40 approximately.Comparison between LRH and ARH in the same period showed that LRH was more splendid than ARH in several index.1 case relapsed in 2-48 months follow-up in ARH while no relapse in the other group. Conclusion LRH is safe and feasible and has good prospects in clinical application and deserves clinical generalization because of its advantages such as less trauma,less pains, quick recovery,less scars and aesthetical appearance.
