Prediabetes is an abnormal condition between normal glucose metabolism and diabetes mellitus. Impaired glucose tolerance (IGT) is an indicator of high-risk state of prediabetes. Positive interventions of IGT, including life style changes and pharmacological intervention, can effectively postpone and reduce the development of prediabetes into type 2 diabetes mellitus, suggesting that IGT is a key point of diabetes prevention. Currently, pharmacological intervention for prediabetes is still at early stage. In this review, we summarizes recent clinical and preclinical studies on pharmacological intervention for prediabetes, and studies in the development of animal models with IGT and the application of new techniques. We also discuss the prospects of drugs for diabetes prevention, especially with the traditional Chinese medicine.

Urinary tract infections remain the most frequent infection in patients with either traumatic or nontraumatic spinal cord inju-ry. The urinary tract infections are closely related to impaired bladder storage, voiding dysfunction, and use of indwelling catheters after spi-nal cord injury. Repeated urinary tract infections can cause upper urinary tract deterioration, and related chronic or repeated exposure to the antibiotics used to treat urinary tract infections increases the risk of multidrug-resistant bacteria colonization. Therefore, it is important to de-termine appropriate urinary tract infections treatment in spinal cord injury patients who are admitted to rehabilitation hospitals. The limita-tions of the usual measures in prevention of urinary tract infections in this population have led the way to explore more innovative modali-ties and approaches. We reviewed the researches of urinary tract infections on spinal cord injury. It is presented to provide reference for clini-cal diagnosis and treatment.

Objective To evaluate the application effect of teaching-picture archiving and communication system (T-PACS) in training image reading ability of eight-year-program students. Methods Sixty students were divided into two groups: control group (applying traditional teaching method) and experimental group (applying traditional teaching method and T-PACS) when doing clinical medical image reading ability training. Making multimedia teaching movie, clinical image reading teaching and establishing image database by T-PACS were used in experiment group. Mean-while, reading room was set up and classroom teaching and problem-oriented assignments were in-creased. Finally objective evaluation of image recognition ability and questionnaire were used to compare the teaching effect. Measurement data were expressed as x±s. Total scores of image reading were am-alyzed by t test. Full score rates were analyzed by X2 test. Results The results showed that the score of medical image reading ability was higher in experimental group (90.08±4.52) than in control group (86.92±4.68) (P=0.010). There were differences in respiratory and orthopedic full score rate (P=0.006;P=0.035). Most students thought that application of T-PACS could effectively improve the teaching and learning quality. Conclusions Application of T-PACS can improve the medical image reading ability of eight-year-program medical students and is worth further promoting.

Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome ( PCOS). The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic (ROC) curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group (both P ＜ 0. 05 ) ; the area under ROC curve ( AUC ) of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.
