Objective To present the distinction on clinical features,laboratory features,treatment schemes between the patients with and without brucellar epididymo-orchitis,and to provide a theoretical basis for clinical diagnosis and treatment.Methods A retrospective analysis of 223 male patients with brucellosis in the First Hospital of Jilin University from June 2010 to November 2016 was carried out.A comparative analysis of the clinical and laboratory features of 22 patients with epididymo-orchitis and 201 cases without epididymo-orchitis was done.The SPSS 23.0 software was used to analyze the statistical results,P ＜ 0.05 was defined as statistically significant.Results Epididymo-orchitis occurred in 9.87％ (22/223) of all male patients with brucellosis.The median ages of patients with and without epididymo-orchitis were 35.5 and 42.0 years old,respectively,the difference was not statistically significant (Z =1.323,P ＞ 0.05).Cases with and without epididymo-orchitis of brucellosis with fever [90.9％ (20/22) vs 69.2％ (139/201)],chills [54.4％ (12/22) vs 28.9％ (58/201)],hepatomegaly [22.7％ (5/22) vs 3.5％ (7/201)],abdominal symptoms [59.1％ (13/22) vs 17.4％ (35/201)],and urinary tract infection symptoms [31.8％ (7/22) vs 3.5％ (7/201)],the differences were statistically significant (x2 =4.586,6.076,14.424,20.392,27.059,all P ＜ 0.05).The medians of white blood cell (WBC) count (7.9 × 109/L),erythrocyte sedimentation value (ESR,38.0 mm/h),and aspartate aminotransferase (AST,110.0 U/L) in brucellosis with epididymo-orchitis were higher than those without epididymo-orchitis (5.1 × 109/L, 30.0 mm/h,73.8 U/L),the differences were statistically significant (Z =2.239,2.064,2.762,all P ＜ 0.05).All brucellosis patients with epididymis-orchitis were treated with antibiotics for 8 weeks.The defervescence time was 4.5 days,the time of pain relief was 3.9 days,21 patients were cured,and only Ⅰ patient relapsed.Conclusions Epididymo-orchitis is a common complication of brucellosis.Brucellar epididymo-orchitis is usually characterized with a severe acute clinical presentation,which needs timely diagnosis.Combination of antibiotics treatment for 8 weeks in brucellosis patients with epididymis-orchitis is effective.

Objective To study the relationship between renal morphology and renal function,and to assess the value of CT as a criterion to grade renal function.Methods Enhancement CT were performed in 89 patients with no local renal disease whose split renal glomerular filtration rates(GFR)were measured by renal dynamic imaging with ~(99)Tc~m-DTPA.The 178 kidneys were divided into normal renal function,mild and severe renal impairment groups according to renal function.Differences between three groups respect to the mean thickness of renal cortex and parenchyma were assessed by ANOVA.Using Pearson's correlation test,the correlation between the renal cortex,parenchyma thicknesses and renal GFR were examined.The value of CT in predicting renal function was assessed by using ROC analysis.Results The renal cortex thicknesses of normal renal function,mild and severe renal impairment groups were(5.9?1.1),(4.6? 1.1),and(3.3?1.0)mm respectively,and the renal parenchyma thicknesses were(26.3?4.2), (21.3?4.6),(16.2?4.6)mm.There were significant differences of renal cortex,parenchyma thicknesses between 3 groups(cortex F=54.78,P

OBJECTIVETo systematically assess the efficacy and safety of Rhodiola in treating chronic stable angina pectoris.

METHODSOur group searched the Cochrane library, PubMed, Embase, Chinese biomedical literature database (CBM), VIP database (VIP), Chinese Journal Full-text Database (CNKI) for the literature published in English and Chinese till April 2013. Randomized controlled trials (RCTs) were included on the therapeutic effect of Rhodiola or Rhodiola plus conventional Western medicine in comparison with the conventional Western medicine treatment on stable angina. Data were extracted according the data extraction form. The literature methodological quality was assessed by using the Cochrane handbook, and data analyzed by Rev-Man 5.2 Software for Meta-analysis. The effect indicators of outcomes was expressed by odds ratio (OR) and 95% CI.

RESULTSA total of 7 randomized controlled trials, 662 cases of stable angina pectoris patients met the inclusion criteria and all published in Chinese, without one scientific design and high quality literature. Compared with the conventional Western medicine treatment, combined with oral administration of Rhodiola could improve the efficiency of anti-angina (OR = 2.49, 95% CI: 1.02 - 6.09). Combined with intravenous infusion of Rhodiola could also improve the efficacy of angina pectoris (OR = 4.86, 95% CI: 2.4 - 9.82). Oral administration of Rhodiola couldn't improve ECG efficacy (OR = 1.25, 95% CI: 0.67 - 2.34). Intravenous infusion of Rhodiola could improve the clinical efficacy (OR = 2.94, 95% CI: 1.61 - 5.35). Combined with the conventional treatment, intravenous infusion of Rhodiola could improve the whole blood viscosity (low and high shear rates) and inverse variance (IV) (-1.36 and -0.99, 95% CI: -1.65 - 1.07 and -1.26 - 0.71), but could not reduce serum fibrinogen and D-dimer level. The incidence rate of adverse reactions was higher than that of the conventional treatment combined with Rhodiola (OR = 0.1, 95% CI: 0.02 - 0.51).

CONCLUSIONSOn the basis of routine treatment, Rhodiola could further improve patients' symptoms. Combined with intravenous medication, Rhodiola could increase the ECG improvement rate, and reduce adverse reactions. But the methodological quality of included studies was poor, the number of samples was small, and influence factors such as the intervention period was short. This conclusion needs scientific and rational design in a larger sample, multicenter clinical trial to verify.

Background Researches determined that the alteration of A69S locus of age-related maculopathy susceptibility 2 ( ARMS2 ) gene is closely associated with the pathogenesis and progression of age-related maculopathy ( AM D ).However,the location of ARMS2 protein in normal eye tissue is still in controversy,therefore,its function is below understanding up to now.Objective The goal of this laboratory work was to investigate the distribution,expression and location of ARMS2 protein in normal adult retina and choroid as well as in retinal pigment epithelial (RPE) cells and lay a basis for exploring further its function in the protein level.Methods Ten donor eyeballs of normal adult male with the age from 28-42 years were collected in eye bank of Qingdao Eye Hospital.The frozen sections of the retina and choroid were prepared for the detection and location of ARMS2 in 3 eyes by immunofluorescence under the confocal laser microscope.The retina was isolated for the primary culture of RPE cells using explant culture method.The cells were then identified by CK32 antibody by immunofluorescence.The distribution and expression of the ARMS2 protein in retina,ehoroid and RPE cells were determined by immunofluorescence technique.Results ARMS2 protein was strongly expressed in retinal vessel,RPE cell layer,Bruch membrane and choroidal vessel,but weak expression was in retinal ganglion cell layer,inner nuclear layer,outer plexiform layer,outer nuclear layer and inner plexiform layer in the normal eyes.The primarily cultured cells appeared the polygon shape with the abundant pigment in cytoplasm.The immunofluorescence of the cells showed the positive response for CK32,exhibiting the green fluorescence granules in the cytoplasm.The positive expression of ARMS2 protein also was seen in the cytoplasm of RPE cells,appearing the red fluorescence.Conclusions ARMS2 protein mainly distribute and locate retinal and choroidal vessels,RPE cells and Bruch membrane in normal eye.

Objective To investigate the imaging features of the nigrosomes-1 region in the substantia nigra at 3.0 T with enhanced gradient echo T2 star weighted angiography(ESWAN), and to explore its clinical value in the evaluation of Parkinson disease (PD). Methods Fifty-four patients diagnosed with PD (PD group), and 51 non-PD volunteers (N-PD group) were scanned with 3.0 T ESWAN, who had selected randomly. The widths of the typical high signal correspondence with the nigrosomes-1 region (a), the width at the middle of the substantia nigra (b) and the width of the banded high signal of which the oval structure were not displayed (c) were measured and collected. The result of reclassification performed by 2 physicians were compared with clinical gold standard. Specificity and sensitivity were calculated; Eleven outpatients with clinically suspected PD but undiagnosed (UD group) were continusouly selected. They received the same scanning and were performed with imaging diagnosis according to the conclusions of previous studies, then compared the imaging diagnosis with the final clinical diagnosis. Results In non PD group, hyperintensity of nigrosomes-1 were shown in 49 cases (96.1%) in bilateral or unilateral of the SN, the hyperintensity were shaped as“drop”, wedge or oval and the average size (a/b) was (0.31 ± 0.07)mm approximately; PD group, all 54 cases (100.0%) of the oval rear the“drop”were completely disappeared. The sensitivity of the loss of the hyperintensity of nigrosomes-1 for the diagnosis of PD was about 100.0%(54/54)and the specificity of it was about 96.08%(49/51). In UD group, 7 cases with the“drop”completely missed and 1 case with smaller“c”were clinically proven to PD, 2 cases with the typical hyperintensity and 2 case with larger“c”were proven to Parkinson plus syndrome. Conclusions The nigrosomes-1 typical hyperintensity in PD patients' substantia nigra on the 3.0 T ESWAN are disappeared. There may be an effective method for PD and Parkinson's plus syndrome identification that by analyzing of the presence or absence of the typical hyperintensity and its size in the patients with symptoms of PD.

This article proposes the "Efficacy Theory" hypothesis of the traditional Chinese medicines (TCMs): TCMs take effects and weaken toxicities through the additive effects of numerous effective forms (including their constituents or/and metabolites) on a same target, the synergistic effects based on the overall action of the additive effects on individual targets and their toxicities scattering effects. A TCM may include approximately 1000 constituents and each constituent may produce about 100 metabolites in vivo after oral administration. Numerous effective forms of incalculable constituents and their metabolites could work like a "army group" together. When the quantity of a specific target molecule is larger than the pharmaceutical molecules, the molecules of different kinds of effective forms could combine with the target molecules successively, to exert the additive effects. When the target molecules are mostly occupied ("target most spaces occupied"), this TCM begins to work. The additive effects maybe exert not only in concentration but also in a time order way, which gives a sustained efficacy of TCM. The additive effects and the toxicities scattering effects are resulted from the same effective groups and not identical toxic groups among different effective form molecules. The "toxicities scattering effect" can be used to explain the non-toxic TCMs, but not fit for toxic TCMs. The efficacy theory showed that the variety of constituents and metabolites may participate in the process of pharmacodynamic actions, including the additive effects, synergy effects and toxicities scattering effects, which may be useful for explaining and developing the characteristic advantage of the TCMs. The questions we need to study or confirm are as follows: What are the TCMs' pharmacodynamic substance basis and mechanism made up of Why are toxicities of most TCMs' smaller How is the TCMs' "Efficacy Theory" which reflects characteristic advantage of TCMs applied in the research and development of new drugs.
