Iliac vein compression syndrome is one of the most common lower extremity venous backflow obstruction disorders,which often causes lower limb swelling,venous stasis dermatitis,lower extremity deep venous thrombosis,lower extremity venous valvular insufficiency,etc.At present the commonly used imaging diagnostic means include ultrasonography,multi-slice computed tomography,magnetic resonance and digital subtraction angiography.This paper aims to review the recent progresses in the imaging diagnosis of iliac vein compression syndrome.

Objective To implement active screening measures for patients in intensive care unit (ICU),early de-tect patients with multidrug-resistant organism (MDRO)colonization,implement contact isolation measures,pre-vent and control MDRO cross transmission.Methods The nasal and rectal swabs of 240 patients who were admit-ted to ICU from September 2012 to May 2013 were performed bacterial culture,patients with colonization of methi-cillin-resistant Staphylococcus aureus (MRSA),extended-spectrum β-lactamases (ESBLs)-producing Escherichia coli ,and ESBLs-producing Klebsiella pneumoniae were conducted contact isolation.Clinically isolated MDROs from ICU patients in September 2011-August 2012 (before active screening)and September 2012-August 2013 (after active screening)were collected and performed antimicrobial resistance analysis.Results Of 240 patients, nasal swabs screening test showed that there were 56(23.33%)patients who were colonized with MRSA,including 22(39.29%)were colonized at the admission to ICU and 34(60.71%)during the ICU stay.Rectal swabs screening test showed that there were 105(43.75%)patients who were colonized with ESBLs-producing Escherichia coli and Klebsiella pneumoniae ,72(68.57%)were colonized at the admission to ICU,and 33(31.43%)were colonized dur-ing the period of ICU stay.The incidence density of MDROs before and after implementing active screening were 28.56‰ and 13.71‰ respectively,difference was significant (P < 0.05;RR,2.08 [95%CI ,1.582 - 2.743]). Conclusion MDRO colonization rate is high among ICU inpatients,implementation of comprehensive prevention and control measures against MDROs based on active screening can reduce the spread of MDROs in ICU.

AlM:To explore the efficacy and safety of mitomycin C used in trabeculectomy by analyzing intraocular pressure and blood flow.METHODS:A total of 103 patients with glaucoma were divided into 2 groups randomly, and all patients were treated with trabeculectomy, while patients in the observation group were given mitomycin C extra. At 6~12mo follow-up were completed after operation, and the clinical efficacy, complications and hemodynamic characteristics of central retinal artery were compared between groups.RESULTS: The clinical efficacy of the observation group was higher than that of the controls (P<0. 05). There was no significant difference in complication rate between groups (P>0. 05), but the complication type was differentiate to some extent. Low intraocular pressure and photophobia symptoms occurred mostly in the observation group, while cicatricial obstruction occurred mostly in the controls. Before treatment, there was no significant difference in hemodynamic characteristics between groups (P>0. 05). One month after treatment, the peak systolic velocity ( PSV) and end diastolic velocity ( EDV ) of the observation group were obviously lower, while resistance index ( Rl ) and pulsatility index ( Pl ) were higher than those of the controls, the difference was statistically significant ( P<0. 05). Six months after treatment, the PSV and EDV of the observation group were obviously higher, while Rl and Pl were lower than those of the controls, the difference was statistically significant (P<0. 05).CONCLUSlON:Mitomycin C has a short-term harmful effect on glaucoma patients after trabeculectomy, but its long-term effect is safe and reliable.

Objective To investigate the expression of DNA methyltransferase 1,3a,3b (DNMT1,DNMT3a,DNMT3b) in human hepatocellular carcinoma (HCC) and to determine their clinical significance.Methods The expression of DNMT1,3a,3b proteins was detected in 47 HCC tumor specimens and 42 HCC paracarcinoma liver tissues by immunohistochemistry.12 normal liver tissues were used as control.The results and clinicopathological parameters were analyzed.Results The positive expression rates of DNMT1,3a and 3b in HCC tissues were 80.9％,68.1％ and 78.7％ respectively.The positive expression rates of DNMT1,DNMT3a and DNMT3b in paracarcinoma tissues were 50.0％,52.4％ and 57.1％ respectively.The expression rates of DNMT1,3a and 3b in both HCC tissues and paracarcinoma tissues were significantly higher than normal liver tissues.The expression of DNMT1,DNMT3a,DNMT3b was correlated with tumor differentiation (P＜0.05) and hepatitis B surface antigen (HBsAg) positivity.Conclusions DNMT1,3a and 3b play important roles in carcinog(c)n(c)sis and development of HCC.

Methods UV spectrum of the absolute alcoholic extract of F. walujewii was determined and compared with that of four other similarly treated Fritillaria species. Results The UV spectrum of F. walujewii was consistently different with that of the other four species. Conclusion UV spectrum can be used to differentiate F. walujewii from other species of Fritillaria.

AIM: To observe the effect of phagotrophic ability of macrophage on pseudomonas aeruginosa which was cocultured with low concentration of erythromycin. METHODS: The pseudomonas aeruginosa ATCC 27853 was cultured in LB both with low concentration of erythromycin (Group A) and without erythromycin (Group B) for 18 h separately, then incubated with macrophage from murine abdominal cavity for 2 h. The ratio of phagocytosis of macrophage was determined by microscope detection. RESULTS: The ratio of phagocytosis of group A in which erythromycin was added was higher than the group B, and the pseudopodia of macrophage were increased in the group A under electron microscope. CONCLUSION: Low concentration of erythromycin may enhance the phagocytosis ability of macrophage in vitro by influencing the virulent factors of PA.

As one of endocrine dysfunction related diseases among children,precocious puberty has trend for increased rates in recent years.Widespread children exposure to known or suspected endocrine disrupting chemicals has been documented in worldwide,in which exogenous estrogen chemicals trigger precocious puberty onset have been attracting more and more attentions.Zearalenone widely contaminates foods such as grain,milk,meat and eggs,which displayed its estrogen effect to disrupt organism development.In this review,Zearalenone is suspected as triggering factor for precocious pubertal to be discussed,will lead to people pay more attentions to food safety and the prevention of precocious puberty.

OBJECTIVETo observe the efficacy difference in the treatment of breast hyperplasia between the combined therapy of auricular point sticking and Xiaopijian and the simple application of Xiaopijian.

METHODSNinety-one patients were randomized into an observation group (46 cases) and a control group (45 cases). In the observation group, the sticking therapy on the auricular points was applied in combination with the oral medication of Chinese herbal medicine, Xiaopijian. Auricular points included Ruxian, Neifenmi (CO18), Luanchan, Shenmen (TF4), Gan (CO2), Pi (CO13). The auricular point sticking therapy was applied once a week on the auricular points of one side alternatively. Xiaopijian was the self-prepared decoction. The main ingredients are radix bupleuri Bupleurum chinense, spica prunellae prunella vulgaris and radix peoniae alba Paeonia lactiflora, 30 mL each time, three times a day. In the control group, Xiaopijian was simply prescribed for oral administration, 30 mL each time, 3 times a day. The treatment was discontinued during menstruation in the two groups. The menstrual cycle of one month made one session of treatment. The treatments for 3 sessions were observed. The scores of symptoms and physical signs, including the degree of breast pain, hardness and size of breast masses as well as the scores of general and supplementary symptoms were compared before and after treatment in the patients of the two groups. The clinical efficacy was compared between the two groups.

RESULTSAfter treatment, the scores of symptoms and physical signs were reduced apparently as compared with those before treatment in the patients of the two groups (both P<0. 05). The score reduction in the observation group was much more than that in the control group (11.02±1. 78 vs 9.82±1. 53, P<0. 05). The total effective rate was 95.7% (44/46) in the observation group, higher apparently than 80. 0% (36/45, P<0. 05).

CONCLUSIONThe combined therapy of auricular point sticking and Xiaopijian achieves the superior efficacy on breast hyperplasia as compared with the simple application of Xiaopijian.
