Objective To investigate the routes and MR imaging manifestations of meningeal involvement by nasopharyngeal carcinoma (NPC) with pathological correlation. Methods Twenty five NPC patients with involvement of meninges were included into the study. All patients underwent both unenhanced and Gd DTPA enhanced MR imaging examinations. Surgical and pathological findings were correlated with MR imaging manifestations in 9 patients. Positive cytology was found in only 1 of the 25 patients. Results There were three main routes for meningeal involvement in NPC patients: (1).through the natural bony channels (foramens) of the skull base; (2).through direct bony erosion of the skull base; and (3).Through hematogenous spread. Dura mater was very frequently involved, being seen in 24 patients; pia mater was involved in only one patient. Irregular, patchy thickening in the form of “necklace”, nodules, or mass with obvious enhancement was the major MR feature of meningeal involvement by NPC. In one patient with choroid plexus involvement, dilatation of the lateral ventricles, subependymal nodules with patchy thickening were observed. Conclusion MR imaging with Gd DTPA enhancement was very useful to demonstrate the presence, location and extent of meningeal involvement in NPC patients.

Objective:To investigate the content rationality of antimicrobial agent thimerosal in chloramphenicol eye drops. Meth-ods:Chloramphenicol eye drops with thimerosal at different concentrations were prepared, and the antimicrobial activity was studied. Results:When the test solution contained 0. 02 mg·ml-1 thimerosal, the antimicrobial activity could achieve the requirement in the pharmacopoeia. Conclusion:Thimerosal at different concentrations in the commercial chloramphenicol eye drops all can reach the anti-microbial effect. However, the thimerosal concentration in some eye drops is unreasonably high, which should be reduced.

Objective: To study whether domestic chloramphenicol eye drops with different ethylparabenin content meet the re-quirements in Chinese Pharmacopoeia. Methods:Antimicrobial effect test was used to examine the antimicrobial effect of the different eye drops. Results:The antimicrobial effect of the eye drops was in compliance with the requirements in the pharmacopoeia. Conclu-sion:The ethylparabenin concentration in the eye drops is higher than necessary. Boric acid and borax not only can adjust pH, but also show antimicrobial effect.

Objective To explore the value of fascial tail sign at MR images in the detection of nodular fasciitis (NF). Methods A retrospective analysis of MR images was performed in 19 patients with pathologically proven NF of the soft tissue and 53 patients with a variety of other fibrous-predominant tumors. MR manifestations of all cases were reviewed by two experienced musculoskeletal radiologists using a single blind method. The presence of fascial tail on MR images were evaluated. ROC was used to assess the value of fascial tail sign in the detection of NF. Sensitivity, specificity, Youden index and area under ROC curve were calculated. The association between the presence of fascial tail sign on MRI and pathological classification of NF was analyzed by Pearson chi-square test for independence . Results Fascial tail was present in 17 cases (89.5%) of the study group and in 6 cases (11.3%) of the control group, respectively, yielding a sensitivity of 89.5%, a specificity of 88.7%, a Youden index of 0.782 and an area under ROC curve of 0.891. The fascial tail sign was significantly associated with NF (c2=39.294,P<0.05,r=0.594). Conclusions Fascial tail sign at MRI is a moderately specific and sensitive for the diagnosis of NF relative to fibrous-predominant tumors. It can be used in differentiate between NF and aggressive soft tissue tumors.

ObjectiveTo investigate the value of ABCR clinical scoring system in guiding repeated transcatheter arterial chemoembolization (TACE) therapy for patients with hepatocellular carcinoma (HCC) and the treatment strategies for patients with an ABCR score of 1-3. MethodsThe patients with HCC who underwent TACE in The First Affiliated Hospital of Soochow University from January 2008 to December 2017 were enrolled. In order to investigate the effect of repeated TACE in patients with different ABCR scores, 229 patients who underwent repeated TACE consecutively (at least twice, without systemic therapy) were enrolled as group A, which was further divided into group A1 with 92 patients (an ABCR score of ≤0), group A2 with 78 patients (an ABCR score of 1-3), and group A3 with 59 patients (an ABCR score of ≥4). In order to investigate the survival time of patients with an ABCR score of 1-3 who received different regimens after first TACE therapy, 118 patients with an ABCR score of 1-3 who received TACE for the first time were enrolled as group B, which was further divided into group B1 with 78 patients (treated with TACE after first TACE therapy), group B2 with 21 patients (treated with TACE combined with sorafenib), and group B3 with 19 patients (treated with sorafenib alone). The survival of the above groups of patients were analyzed. The Fisher’s exact test was used for comparison of categorical data between groups, the Kaplan-Meier method was used to plot survival curves, and the log-rank test was used for comparison of survival time between groups. ResultsThe median survival time was 320 months (95% confidence interval ［CI］: 27.7-36.3) in group A1, 10.3 months (95%CI: 8.4-12.2) in group A2, and 4.6 months (95%CI: 3.7-5.5) in group A3. Group A1 had a better survival time than group A2 (χ2=106.99, P＜0.01), and group A2 had a better survival time than group A3 (χ2=49.66, P＜0.01). The median survival time was 10.3 months (95%CI: 8.4-12.2) in group B1, 14.8 months (95%CI: 7.8-21.8) in group B2, and 6.0 months (95%CI: 4.6-7.4) in group B3, and group B2 had a better survival time than group B1 (χ2=6.80, P＜0.01) and group B3 (χ2=29.89, P＜0.01). ConclusionThe ABCR score has a certain guiding significance for the treatment of HCC patients. Repeated TACE may be considered for patients with an ABCR score of ≤0, while patients with an ABCR score of ≥4 may not benefit from further TACE therapy, and TACE combined with sorafenib might bring maximum benefits to patients with an ABCR score of 1-3.

【Objective】 To study the status and conduct effect evaluation of blood donation recruitment of blood services in Chongqing, and explore its influencing factors, so as to provide reference for the regional homogenization of blood services in Chongqing. 【Methods】 19 blood services in Chongqing were investigated by questionnaire in terms of the input in human resources and funds, recruitment methods, document construction and effect evaluation. The statistical analysis was conducted. 【Results】 The average number of blood donors per 1 000 population in 19 blood services in Chongqing was 9.35±3.35. Among the 19 blood services, blood inventory warning occurred in 18, 6 of them reached Level 2 and 1 of them was Level 1. The number of blood donations per 1 000 population in blood banks with no more than 5 recruits or with less than 100 000 yuan/year recruitment fund was significantly lower than that in blood banks with more than 5 recruits or with more than 100 000 yuan/year recruitment fund(P<0.05). SMS and telephone recruitment were most commonly used in blood donation recruitment. Most blood banks have established corresponding system documents, but only one has established the method to evaluate the effect of blood donation recruitment. 【Conclusion】 The number of blood donations per 1 000 population in 19 blood services in Chongqing varies greatly, and the pressure of blood inventory warning is widespread. The input of human resources and financial fund have a certain impact on the number of blood donations per 1000 population, but not the alone factor. The recruitment method is a little bit more on the traditional side, and the blood donation recruitment and efficacy evaluation is in lack of documentary supporting. Regional homogenization should be achieved by integrating the resources of blood services, establishing the document framework of blood donation recruitment and effect evaluation, clarifying the evaluation content and unifying the evaluation standard.
