Objective To compare the sensitivity and specificity of NMP 22 test with voided urine cytology in detection of bladder cancer and to evaluate their clinical values. Methods For 155 patients suspected with bladder cancer NMP 22 and cytology were conducted in the same voided urine samples.Of them 95 patients with bladder transitional cell carcinoma were confirmed histologically.The sensitivity and specificity of NMP 22 and urine cytology were analyzed.60 patients without bladder cancer were selected as control. Results The overall sensitivity and specificity of NMP 22 test were 65.3% and 70.0%,respectively,those of urine cytology were 43.2% and 83.3%,respectively.There was no significant difference between the specificity of urine cytology and that of NMP 22 test;however,NMP 22 was significantly more sensitive than urine cytology in detection of any stages and grades of bladder cancer(P

OBJECTIVETo observe the clinical effect of Guilu Erxian Glue Cataplasm (GEGC) on carcinoma of the large intestine patients with myelosuppression after chemotherapy, and further to confirm its efficiency and safety.
METHODSTotally 60 patients with carcinoma of the large intestine were randomly assigned to two groups. Meanwhile, they all accepted FOLFIRI chemotherapy. Patients in the treatment group were additionally applied at Shenque (RN8), exchanging once per every other day, for 14 successive days. Patients in the control group took placebos with the same dose and dosage as the treatment group. The blood cell counts (WBC, NE, and PLT) were detected before chemotherapy, at day 7, 10, and 14. The TCM symptoms integrals, Karnofsky performance score (KPS), liver and kidney functions were observed before chemotherapy, at day 7 and day 14. Adverse skin reactions were observed each day. And the usage of hematopoietic growth factors was recorded.
RESULTS(1) The KPS score at day 7 was more stable in the treatment group than in the control group; the WBC and NE counts in the peripheral blood at day 14 were higher in the treatment group than in the control group; and TCM symptoms integrals at day 14 was lower in the treatment group than in the control group, all with statistical difference (P < 0.05). (2) Compared with the control group, the PLT count was higher in the treatment group than in the control group, the usage of rhG-CSF and antibiotics was less in the treatment group than in the control group, all with no statistical difference (P > 0.05). (3) No obvious adverse reactions such as liver injury, renal injury, or skin allergy were observed.
CONCLUSIONSAdjuvant treatment of GEGC could improve carcinoma of the large intestine patients with myelosuppression to some extent. No relevant adverse reactions were found.

Objective To prepare a kind of superparamagnetic iron oxide (SPIO) and doxorubicin loaded multifunctional polymer microbubbles (MPMBs),and to explore its potential application as an ultrasound(US)/magnetic resonance (MR) imaging contrast agent in vitro.Methods The MPMBs and normal polymer microbubbles (PMBs) were made by double emulsion and freeze-drying methods.The physical property,drug encapsulation efficiency and the drug-loading efficiency of MPMBs were determined,and the release property and US/MR imaging enhancement of MPMBs were observed.Results The MPMBs had a regular shape and narrow size distribution.The drug encapsulation efficiency was (60.20±2.69) %,and the drug-loading efficiency was (6.02 ± 0.27) %.The in vitro release experiment showed that ultrasound can promote the release of doxorubicin in MPMBs.US imaging in vitro showed that the enhancement of MPMBs was better than PMBs,and MR imaging in vitro conformed that MPMBs could well enhance MR imaging.Conclusions The MPMBs is a multifunctional contrast agent with the treatment function as well as US/MR dual-mode imaging enhancement effect.

Objective To prepare polyclactic-co-glycolic acid(PLGA) polymer ultrasound contrast agent loading sudan black dye (SB-PLGA) and study the enhancement effect of it on rabbit lymph nodes imaging and as a sentinel lymph node (SLN) biopsy in the feasibility and value of the indicator.Methods SB-PLGA ultrasound contrast agent was made by double emulsion and freeze-drying methods.Thigh subcutaneous rabbit VX2 tumor model of eight lymph nodes were set up with the foot pad subcutaneous injection of contrast agents to get contrast-enhanced ultrasound imaging of the popliteal lymph node and the second inguinal lymph node stations.Then the blue stained lymph nodes were resected by popliteal lymph node dissection and the second station lymph nodes were also observed after 30 mins respectively,lymph nodes were examined by frozen sections HE staining in parallel.Results SB-PLGA microbubbles had a tight size distribution.Ultrasound imaging can be significantly enhanced lymph node imaging,the second station lymph node imaging was not obvious.Popliteal lymph node dissection for lymph node staining,30minutes later,frozen sections HE staining were seen within the lymph node contrast agent present in the lymphatic sinus and a large entry of macrophages.Inguinal lymph node dissection showed the second station of lymph nodes no blue staining.Conclusions SB-PLGA ultrasound contrast agent is good for sentinel lymph node imaging and biopsy indicator.Contrast agent retention and accumulation in the lymph nodes by the uptake of macrophages may be associated with the mechanisms of lymph node enhanced imaging.

A novel method for the simultaneous quantification of seven metabolites of polycyclic aromatic hydrocarbon in human urine was developed using online solid phase extraction-HPLC with double ternary liquid chromatography system combined with fluorescence detector. The target compounds were online concentrated on the Turboflow Cyclone solid phase extraction column at first, then transferred by the six-way valve to the Hypersil Green PAH column for separation with acetonitrile and water as mobile phase at a flow rate of 1. 0 mL/min and at 35 ℃. A single sample analysis cycle took only 20 min. Under the optimized chromatographic conditions, the method showed good linear relationship ( r≥0. 999 ) in the range of 5-2000 ng/L or 50-20000 ng/L. The LODs were 0. 5-15 ng/L, and the recoveries were 80. 7%-110. 7%. The proposed method was successfully applied in the detection of metabolites of polycyclic aromatic hydrocarbons in urine from several smokers and non-smokers. The concentrations of 2-hydroxynaphthalene, 1-hydroxynaphthalene, 2-hydroxyfluorene, 2-hydroxyphenanthrene, 4-hydroxyphenanthrene and 6-hydroxychrysene in the smokers urine were much higher than that in non-smokers.

Objective:
To explore the association of hypertriglyceridemic waist phenotype ( HTGW ) with impaired fasting glucose ( IFG ) and diabetes, so as to provide reference for the early prevention and control of diabetes.
Methods:
The survey was conducted among 35 to 75-year-old residents in 8 project sites in Jiangsu Province from 2015 to 2019. The information about demography and lifestyle was collected by the general information questionnaire and the primary screening questionnaire from the National Center for Cardiovascular Diseases; waist circumference, height, weight, triglyceride, high-density lipoprotein cholesterol, total cholesterol and fasting plasma glucose were measured. The multinomial logistic regression model was employed to analyze the association of HTGW with IFG and diabetes.
Results:
A total of 118 383 subjects were included, among whom 21 851 cases of HTGW, 27 245 cases of IFG and 22 899 cases of diabetes were identified, with the prevalence of 18.46%, 23.01% and 19.34%. The multinomial logistic regression analysis showed HTGW was statistically associated with IFG ( OR=1.414, 95%CI: 1.343-1.489 ) and diabetes ( OR=2.216, 95%CI: 2.098-2.341 ).
Conclusion
HTGW is associated with IFG and diabetes, which make it possible to be an indicator for screening and assessment of glucose abnormality in middle-aged and elderly population.
