Objective To explore the risk factors for urinary tract infections in type 2 diabetes mellitus(T2DM )by analyzing the pathogens distribution characteristics and drug sensitivity. Methods A total of 3 ,065 T2DM patients were retrospectively analyzed for the clinical and etiological characteristics of urinary tract infections in T2DM. All patients enrolled in the study were divided into two groups :T2DM with urinary tract infection group (n= 210) and simple T2DM group (n= 132). Data harvested were analyzed by SPSS 19.0. Results Of 3 ,065 patients with T2DM the incidence of urinary tract infection was 6.85%. Compared with T2DM group ,patients in T2DM+ urinary tract infection group were older , with longer duration of diabetes ,higher levels of FPG ,urea nitrogen ,creatinine and 24 hUAlb ,and lower levels of serum albumin ( P< 0.05 ). Logistic regression analysis showed that age ,gender ,duration of diabetes and 24 hUAlb were risk factors and albumin was protective factor for urinary tract infection in T2DM. 84.2% was gram-negative bacteria among the 210 isolated strains of pathogenic bacteria. The top three pathogens were Escherichia coli (65.2% ) ,Enterococcus faecalis (6.2% ) and Klebsiella pneumoniae (5.2% ). Gram-negative bacteria had high sensitivity to Imipenem (100% ) ,Cefoperazone sulbactam (99.2% ) and Amikacin (99.2% ) but low sensitivity to cephalothin (38.1% ) ,piperacillin (35.7% ) and amoxicillin (28.2% ). Conclusion T2DM patients who have the factors including female ,advanced age , long course of diabetes and renal insufficiency are prone to suffer from urinary tract infection. Gram-negative bacteria are the most common pathogens in T 2DM patients with urinary tract infection but bacteria spectrum has changed with percentage of multiple resistant bacteria rising dramatically.

OBJECTIVETo evaluate the therapeutic effects of transcatheter arterial chemoembolization (TACE) with or without radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) patients based on propensity score matching.

METHODSA logistic regression model was established with the treatment assignment as the dependent variable and the covariates as the independent variables. For each HCC patient, the propensity score was calculated from the model for caliper matching, and a survival analysis of the matched data were carried out.

RESULTSThe covariates between the groups were balanced after caliper matching based on the propensity scores. Before matching, the one-, two-, and three-year survival rates of TACE and TACE+RFA were 52.07% and 59.08%, 32.24% and 36.43%, and 316.54% and 19.39%, with the median survival time of 1.20 and 1.40 years, respectively, showing no significant differences in the overall survival rate between the two groups. After matching, the 1-year, 2-year, and 3-year survival rates of TACE and TACE+RFA groups were 54.39% and 62.28%, 23.15% and 40.08%, and 10.20% and 18.52%, with the median survival time of 1.10 years and 1.50 years, respectively, showing significant differences in the overall survival between the two groups. The survival rate in TACE+RFA group was higher than that of TACE only group.

CONCLUSIONPropensity score matching can effectively reduce the confounding bias of non-randomized clinical observational data for a more accurate evaluation of the therapeutic effect in HCC patients.

Based on HRP (Hospital Resource Planning) system's device management module, A new online information management system is proposed and realized to meet the new challenge of medical devices' repairing and maintenance. the traditional telephone report or online report can all be deal. the repair progress can be visualized in real time PM planning and it's early warning are added.

PURPOSE: This cone-beam computed tomography (CBCT) study aimed to analyze the anatomical characteristics of alveolar bone at mandibular first molar (MFM) and their implications for immediate implant placement surgery. MATERIALS AND METHODS: 100 patients with 140 MFMs were reviewed retrospectively. We first performed a 3D reconstruction of the patient’s CBCT data to determine a reference plane with ideal implant placement and orientation. The following parameters of MFM region were analyzed: mesial-distal socket size (MDSS), buccal-lingual socket size (BL-SS), root furcation fornix to inferior alveolar nerve (IAN) distance (RF-I), interradicular bone thickness (IRB), mesial/distal root apex to the IAN distance (MRA-I/DRA-I), thickness of the buccal/lingual bone of the mesial root (MR-B/MR-L), thickness of the buccal/lingual bone of the distal root (DR-B/DR-L). RESULTS: The MD-SS of MFM was 8.74 ± 0.76 mm, and the BLSS was 8.26 ± 0.72 mm. The MR-B, DR-B was 1.01 ± 0.40 mm and 1.14 ± 0.50 mm, and the difference was statistically significant (P = .001). The values of the MR-L, DR-L were 2.71 ± 0.78 mm and 3.09 ± 0.73 mm, and the difference was also statistically significant (P < .001). The mean distance of RF-I was 15.68 ± 2.13mm, and the MRA-I was 7.06 ± 2.22 mm, which was greater than that of DRA-I (6.48 ± 2.30 mm, P < .001). The IRB at 2 mm, 4 mm apical from the furcation fornix, and at apex level was 2.81 ± 0.50 mm, 3.30 ± 0.62 mm, and 4.44 ± 1.02 mm, respectively. CONCLUSION There is relatively sufficient bone mass in interradicular bone in height, but an adequate width is lacking for the bone between the mesial and distal root after the extraction of the MFM for immediate implantation. The thickness of the MFM buccal bone is relative thin, especially for the mesial root.
