Objective The purpose of this study was to edit and psychometrically equate a set of Mandarin bisyllabic word lists. Methods 964 bisyllabjc words were recorded by male talker of standard Mandarin,352 words were selected to compose 10 lists. Percentage of correct word recognition was measured for each word at four intensity levels using 20 normal hearing subjects. The order of the presentation of the lists was randomized for each subject. U-sing Statistica7.0 Performance-Intensity function for each word was plotted,slopes and thresholds of them were calculated. 242 words were chosen after that, The thresholds and slopes of these words were in Guassian distribution. These words were ligitally adjusted and included in six Mandarin bisyllabic word lists of 40 words each. Two of them were for practice, four of them for test. 36 subjects with normal hearing served in our equivalent test. The orders of the presentation of the lists were randomized far each subject and results were expressed as thresholds. Results Two-factor ANO-VA was used to compare the thresholds of the 4 lists, F=1.978,P = 0.209. Conclusion These lists were considered to be primarily equivalent with each other.

Objective To investigate whether antiseptic central venous catheters (CVC) modified with chlorhexidine acetate and silver sulfadiazine can be beneficial in reducing bacterial colonization and catheter-related infection. Methods Prospective controlled non-blinded randomized clinical trial was conducted. Seventy adult inpatients with CVC from intensive care unit of General Hospital of Chinese People's Armed Police Force during June 2007-June 2009 were enrolled. Their baseline characteristics, APACHE Ⅱ score and therapeutic interventions were comparable. Patients were randomly received either an antiseptic CVC ( antiseptic group, n = 28) or a standard two-lumen CVC ( control group, n = 42 ). Microbiological evaluation was done after CVC removal. A catheter bacterial colonization ( CBC) was considered if bacterial growth of > 15 CFU was found by semi-quantitative roll-plate technique from a proximal or distal catheter segment. A catheter-related infection ( CRI) was defined as a colonized catheter with local signs of inflammation. A catheter-related bloodstream infection ( CR-BSI) was defined as a colonized catheter with isolation of the same organism from the patient' s blood with accompanying clinical signs of infection. SPSS 11.5 software was used for statistical analysis. Kaplan Meier curve was used to evaluate the association between CVC retention time and bacterial colonization or infection, and Log-rank test was performed to compare between the groups. Results CVC was removed from 3.6% (1/28) patients of antiseptic group and 21.4% (9/42) patients of control group because of infection (x2 = 5. 143, P <0. 05). Colonization of CVC was observed in 7. 1% (2/28) patients from antiseptic group and 35. 7% ( 15/42) from control group (x2 =7.458, P<0.01). CBC or CRI was not observed in antiseptic group until day 19, while CRI occurred at day 6 in the control group. CVC colonization and infection were developed in 31.4% and 14. 3% patients of antiseptic group during day 14-day 28 respectively, while the rates in the control group were 90% and 70% ( u = 27.5 and 14.31, P < 0.01). Conclusions Antiseptic CVC modified with chlorhexidine acetate and silver sulfadiazine can significantly lower the risks of CBC and CRI. But more than 50% patients would develop infection when colonization occured, no matter patients receive standard or antiseptic CVC. After CVCs have been inserted for > 2 weeks, the colonization and infection will increase significantly in both standard or antiseptic CVC, so to shorten the insertion time is an effective measure to decrease the CVC-related infection.

Objective:To evaluate the quality of the current foreign clinical practice guidelines (CPG) on obstetric venous thromboembolism (VTE), providing reference for standardizing the prevention and treatment of domestic VTE clinical practice.Methods:The GPGs for the management of obstetric VTE published abroad from inception to July 2020 were electronically searched. Two researchers independently evaluated the quality of the included guidelines in accordance with the internationally recognized guideline evaluation tool, AGREE Ⅱ.Results:A total of 12 guidelines, 2 recommendations and 1 consensus for obstetric VTE were included, covering 3 continents and 9 countries, and the published time span was 2009-2020. The standardized scores of the six domain (scope & purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability and editorial independence) included in the guidelines were: 99.44%, 62.78%, 70.35%, 95.74%, 68.80% and 76.94% respectively, and the scores in each domain were ≥ 50.00%, indicating that the included CPGs were of good quality. Except for the domain scope & purpose, the ranges of the other five domains were ≥ 50.00%, suggesting that the quality of the CPGs differed significantly. Among the 15 included CPGs, 4 CPGs were level A (recommended), 11 CPGs were level B (recommended after being revised), and there was no CPG in level C (not recommended). The difference in the recommended content of obstetric VTE management mainly focused on the risk assessment, drug type, dosage and period.Conclusions:The overall quality of the CPGs for obstetric VTE management is high, while the quality of the CPGs varies greatly. In addition, there are differences in the recommended content of obstetric VTE management. More high-quality researches are required to provide evidence-based support for the improvement of the CPGs.

Objective To study spiral CT features and pathological basis of nodular goiter ,so that to improve the diagnostic accuracy of nodular goiter.Methods CT findings in 34 patients with nodular goiter confirmed by pathology were retrospectively analyzed and compared with pathological findings. Results Thyroid density in the patients with NG was lower than that in the normal. There was no statistically significant difference in the density between single and multi-NG. Most lesions(28/34) were multiple, round or oval, with different size and smooth edges. The density of majority lesions was lower than nearby normal tissue. Most lesions (27/34) were uniform in density. Central necrosis(5/34)often appeared in the bigger lesions(diameter>3.0 cm). The CT value of the lesions was increased (47.1±42.2) HU after enhancement,but lower than surrounding thyroid tissue. Calcifications in the lesions(6/34)were puncticular,plaque or crustiform. Single or multiple cystic-solid or solid nodules could be seen in pathology, without a continuous capsule in the majority. Some patients (5/13) with single NG shown on imaging study were multi-NG in the pathology. Three cases of diffuse NG showed by CT were malignant in pathology. Conclusion There are certain characteristics for NG on spiral CT. Comprehensive evaluation may improve the accuracy of CT diagnosis.
