OBJECTIVETo observe the prevention and clinical efficacy of combination of Liuwei Dihuang Pill (LDP) and Ginkgo Leaf Tablet (GLT) for early diabetic retinopathy (DR).

METHODSUsing randomized, double-blind, double simulation, parallel controlled clinical trial, 140 type 2 diabetes mellitus (T2DM) outpatients were recruited and assigned to the treatment group and the control group, 70 in each group. All patients received basic Western medicine treatment (such as blood glucose and pressure control). Patients in the treatment group took LDP (8 pills each time, 3 times per day) and GLT (19.2 mg each time, 3 times per day), while those in the control group took LDP placebos and GLT placebos. All treatment lasted for 24 consecutive months. All subjects were followed-up every month. The general clinical data as sex, age, and metabolic data such as blood glucose, blood pressure, blood lipid, and DR prevalence rate were collected and statistically analyzed.

RESULTSThere was no significant difference in levels of blood glucose, blood pressure, or blood lipid between the two groups (P > 0.05). After treatment the DR incidence rate was significantly lower in the treatment group than in the control group [3.1% (2/64) vs 18.6% (11/59), P < 0.05)]. Meanwhile, the DR prevalence rate of the treatment group was also significantly lower than that of the control group [6.3% (4/64) vs 20.0% (13/59), P < 0.05].

CONCLUSIONCombination of LDP and GLT could effectively prevent and treat the development of DR in T2DM patients.

Objective To check the maneuverability of the nursing safety management indicators for skilled nursing facilities.Methods A hospital based skilled nursing facility in Chongqing was chosen as the main study target while a Red Cross nursing hospital in Shanghai which operated earlier was also included as a comparison object.Combination of files reference,on-the-scene observation,manager interviews,sampling survey and institution's self-assessment,scores of indicators were calculated,and the total scores for both institutions were calculated as well.Results The institution from Chongqing marked 81 points while the other one got 86 points.Conclusions The indicator system had good maneuverability and the weight of indexes was consistent with the practical requirement of safety management.This indicator system could provide reference for standardize skilled nursing facilities' management,but still needed further revision and consummation.

Objective To study the clinicopathologic features and differential diagnosis of deep angiomyxoma(DAM). Methods Seven cases of DAM were collected from 2000 to 2008. All the patients were examined by microscopy and immunohistochemistry. Results 6 patients with DAM were females and 1 was male, with median age of 48.5 years. Median maximum dimension was 5.9cm, with invasive growth pattern. The tumor cells of DAM were infantile, spindle or stellate,diffuse and nodular arrangement. A distinctive histologic feature of DAM was its vascularity. Non-arborizing, thin-wall, ectastic capillaries or more commonly, small thick-wall vessels were dispersed throughout the tumor. Mast cells and extravasated red blood cells were frequently found in the stroma, immunohistochemical study showed that 7 cases were positive for vimentin, desmin, ER and PR, 5 for CD34 and SMA, and negative for S-100 and CK. Conclusion DAM is a rare soft tumor that occurs principally in the vulval and vagina region of woman. Misdiagnosis has happened frequently. Immunohistochemical staining are helpful to diagnosis for DAM, but no significance to distinguish it.

Sleep quality is closely related to human health. It is very important to correctly discriminate the sleep stages for evaluating sleep quality, diagnosing and analyzing the sleep-related disorders. Polysomnography (PSG) signals are commonly used to record and analyze sleep stages. Effective feature extraction and representation is one of the most important steps to improve the performance of sleep stage classification. In this work, a collaborative representation (CR) algorithm was adopted to re-represent the original extracted features from electroencephalogram sig- nal, and then the kernel entropy component analysis (KECA) algorithm was further used to reduce the feature dimension of CR-feature. To evaluate the performance of CR-KECA, we compared the original feature, CR feature and readied CR feature (CR-PCA) after principal component analysis (PCA). The experimental results of sleep stage classification indicated that the CR-KECA method achieved the best performance compared with the original feature, CR feature, and CR-PCA feature with the classification accuracy of 68.74 +/- 0.46%, sensitivity of 68.76 +/- 0.43% and specificity of 92.19 +/- 0.11%. Moreover, CR algorithm had low computational complexity, and the feature dimension after KECA was much smaller, which made CR-KECA algorithm suitable for the analysis of large-scale sleep data.

With constant development and application of new generation information technology such as big data, cloud computing and Internet of Things, traditional management style and thought patterns of TCM are being changed. It is particularly important to introduce information security into budget management of TCM projects. This article discussed security factors in TCM budget monitoring platform, organized key contents of information security construction, built information security model for monitoring platform, and analyzed security strategies for the construction of TCM budget monitoring platform, with a purpose to guarantee effective implementation of budget information management measures of TCM projects.

Objective To investigate the expression level of miRNA-146a (miR-146a) in retinal pigment epithelial (RPE) cells aging and age-related macular degeneration (AMD),and discuss its regulation mechanism of AMD by repressing VEGF-A.Methods The expressions of miR-146 and VEGF-A were examined by qRT-PCR in RPE cells in mice aged 2 months,8 months,12 months,18 months or 24 months,and in RPE cells from 75 years old AMD patients.The protein level of VEGF-A was also detected by Western Blotting.Finally,the effects of overexpression of miR-146a in APRE-19 cell line on expression of VEGF-A was checked.Results MiR-146 was up-regulated to 8 times or 24 times at 18 months or 24 months aged mice,and the expression of VEGFA was down-regulated in aging RPE from 1.5 times to 0.8 times.However,the expression of miR-146 decreased to 14.5 times and VEGF-A increased in RPE cells of AMD.In cultured cells,overexpression of miR-146a inhibited the expression of VEGF-A.Conclusion Up-regulation of miR-146a in aging RPE cells and its down-regulation in AMD suggest a potential of miR-146a as molecular marker.MiR-146a overexpression inhibits the expression of VEGF-A,supporting a potential clinical treatment of miR-146 in AMD.

Currently, bacterial resistance situation in health care settings is very serious in China, and the prevalence of a variety of common multidrug-resistant bacteria and pan-resistant bacteria are relatively high. Drug-resistant bacteria in Gram-positive bacteria are mainly methicillin resistant Staphylococcus aureus ( MRSA ) and macrolide-resistant Streptococcus, while glycopeptide-resistant enterococci are still at a low level.The clonal distribution of MRSA and mechanisms of Streptococcus resistance in China are different from those in European and American countries.Cephalosporins and quinolones resistance are the marked characteristic of Enterobacteriaceae with a high occurrence over 60%. Carbapenem-resistant Klebsiella pneumoniae shows a rapid upward trend, and producing KPC-2 type carbapenemases is the main mechanism of its resistance.Resistance in Pseudomonas aeruginosa is relatively stable, with resistant rates ranging from 20%to 30%.Multi-drug resistant Acinetobacter baumannii is a big problem in clinic.More than 50% Acinetobacter baumannii strains are resistant to carbapenems and cephalosporins, and tigecycline-resistant Acinetobacter baumannii is increasing.This paper systematically reviews the status and characteristics of bacterial resistance in last five years with referring to the surveillance data of antimicrobial resistance and the findings of related mechanisms.
