Objective To establish the CT criteria of quantitative diagnosis for liver steatosis by means of studying the CT features of fatty liver cases proven histologically. Methods Twenty-eight cases of fatty liver were underwent non-enhanced CT scan, and the attenuation of liver parenchyma was measured. To differentiate the degree of fatty liver, the mean CT value and the relative density of hepatic vessels were observed. The quantitative diagnosis was made according to the CT number threshold and the criteria of relative density of hepatic vessels, respectively. Results Among the 28 cases, there were 17 cases of mild steatosis with mean CT number of 46 HU (32-65 HU), 7 cases of middle degree fatty liver with mean CT number of 28 HU (15-38 HU), and 4 cases of sever fatty liver with mean CT number of 0.2 HU (-7-11 HU). For the relative density of hepatic vessels, 16 of the 17 cases of mild fatty liver had a appearance of hepatic vessels immersion and 1 mild case had reverse hepatic vessels display, 6 of 7 middle degree cases had reverse hepatic vessels display with 1 case having the appearance of hepatic vessels immersion, and all the 4 case of sever steatosis had the appearance of reverse hepatic vessels display with sharp contrast between vessels and the liver parenchyma. The accuracy of quantitative diagnosis was 65.9% and 93.1% by means of criteria of CT number threshold and relative density of hepatic vessels, respectively (? 2=7.153,P

OBJECTIVETo determine the recognition of healthy medical students on deqi after acupuncture, reveal the qualitative and quantitative rules of deqi and understand whether these rules are the factors of the clinical application of acupuncture therapy.

METHODSThe class questionnaires were used for the investigation study on the understanding of deqi after acupuncture at Hegu (LI 4) or Zusanli (ST 36) in 86 healthy students in the clinical medicine class.

RESULTS(1) Deqi was a kind of complicated compound feelings, with many sensation qualities such as distending pain, distension and pain. (2) Deqi was a kind of mild and moderate sensations. In 10-score credit sys tem of Massachusetts General Hospital acupuncture sensation scale (MASS), the scores of distending pain (4.69 +/- 2.83), distension (4.39 +/- 2.91) and soreness and distension (3.93 +/- 2.93) were around 5 (moderate degree), the scores of stabbing pain (1.89 +/- 2.02) were around 2 (mild degree). (3) The differences in the quantitative scores were significant for stabbing pain, distending pain, distention, soreness and distention and the others before and after treatment (all P<0.05).

CONCLUSIONDeqi of acupuncture is the mild and moderate complicated sensations manifested as distension, soreness, pain and numbness. As the invasive therapy, the filiform needle puncture will bring a certain psychological impacts on the receptors. The subjective sensation is possibly the factor for the patients' selection of acupuncture treatment.

OBJECTIVE To find out the status about detection and drug resistance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) of urogenital tract infection in Shaoxing area of Zhejiang Province.METHODS The detections and drug sensitive tests of Uu and Mh adopting the reagent boxes produced by bioMerieux Company in France were made.RESULTS In 2678 samples of suspicious urogenital tract infection patients,980 samples cultured of mycoplasma were positive,and the positive rate was 36.6%.Among these cases,763 samples(28.5%) were Uu positive;116 samples(4.3%) were Mh positive.In the drug sensitive test,Uu and Mh were most sensitive to PRI,JOS,DOX and TET.To CFLX,OFL,ERY,CM and AM,they had the highest level of drug resistance.CONCLUSIONS The clinical therapy of mycoplasma infection ought to choose the appropriate antibiotics based on the results of the drug sensitive test of the laboratory.

Sixteen compounds including daphnoretin (1), isofraxidin (2), scopoletin (3), kaempferol (4), quercetin (5), guaijaverin (6), astragalin (7), quercetin-3-O-β-D-glucopyranoside (8), naringenin-7-O-β-D-glucopyranoside (9), 5-O-methylapi- genin-7-O-β-D-glucopyranoside (10), methyl gallate (11), prionitiside A (12), (2S)-2,3-dihydroxypropyl-1,6,8-trihydroxy-3- methyl-9,10- dioxoanthracene-2-carboxylate (13), 3,3'-di-O-methyl ellagic acid (14), 3'-O-methyl-3,4-O,O-metheneellagic acid-4'-O-β-D- glucopyranoside (15) and 3,4-methylenedioxy-3'-O-methylellagic acid (16), were isolated from the 70% acetone extract of Euphorbia dracunculoides Lam. Among them, compounds 1-3, 6-9, 11, and 14 were isolated from E. dracunculoides for the first time, and compounds 10, 12, 13, 15, and 16 were firstly obtained from the genus Euphorbia. Their structures were elucidated by spectroscopic analysis, including 1H-NMR, 13C-NMR, and ESI-MS.

AIM: To investigate the effects and mechanism of enalapril on nephritis of diabetic mice. METHODS: Diabetes was induced by injection of streptozotocin after uninephrectomy. Rats were randomly divided into three groups: control, diabetes, diabetes treated with enalapril (10 mg?kg~-1 ?d~-1 by gavage). 8 weeks after STZ injection, urine albumin excretion rate (AER) were measured, and glomerular morphology were observed by light microscopy. The levels of malonyldialdehyde (MDA) in renal tissue and urine as well as activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-PX) in renal tissue were determined. Immunohistochemistry for ED-1 (macrophage marker), monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1) were performed by streptavidin-biotin complex (SABC) technique. RESULTS: Increased kidney weight, ratio of kidney weight to body weight, AER and expansion of mesangial as well as tuft areas on histological examination of the kidney were significantly attenuated by the treatment of enalapril (P

Objective To discuss training of the nurses in outpatient blood collection room with the digital training modular of blood sample collection to improve the quality of blood sample collection.

Objective To investigate the safety and feasibility of intraluminal brachytherapy using iodine-125 seed strand for locally advanced pancreatic ductal adenocarcinoma with obstructive jaundice.Methods Clinical data of 17 consecutive patients,from January 2010 to February 2015,diagnosed with pancreatic ductal adenocarcinoma (4 cases of T4 N0 M0 and 13 of T4 N1M0) with obstructive jaundice and received intraluminal brachytherapy using iodine-125 seed strand were collected and analyzed retrospectively.Liver function was evaluated using paired-samples t test.The iodine-125 seed strand radiation doses were calculated using iodine-125 radiation field distribution calculation software (version 0.1,Institute of Radiation Medicine,Fudan University,Shanghai,China) based on the American Association of Physicists in Medicine TG43U1 brachytherapy formula.Obstruction free survival and overall survival were calculated using the Kaplan-Meier method.Complications were assessed according to the CTCAE 4.0 criteria.Results The estimated mean accumulating dose (r =5 mm,240 days) was 167.2Gy,from 164.19Gy to 170.05Gy.The mean and median obstruction free survival time were (9.62 ± 1.47) months (95％CI:6.73-12.50) and (7.26 ± 1.71) months (95 ％CI:3.90-10.62).The mean and median overall survival time were (9.89 ± 1.59) months (95％CI:6.78-13.00) and (7.26 ± 1.71) months (95 ％ CI:3.90-10.62),retrospectively.Total bilirubin and conjugated bilirubin decreased significantly after the therapy.Two patients had adverse event of Grade 3,one of Grade 4.Stent dysfunction occurred in 1/17 (5.9 ％) patients.Conclusions Intraluminal brachytherapy using iodine-125 seed strand might be considered as a safe treatment option for the locally advanced pancreatic duct adenocarcinoma complicated by obstructive jaundice.

Objective:To analyze the drug resistance of Pseudomonas aeruginosa( PA) isolated from clinical specimen to provide the guidance for the clinical treatment. Methods:The infection status of PA from January 2012 to December 2012 was reviewed retro-spectively, and the results of susceptibility test for 448 PA strains were analyzed. Results:The antibiotic susceptibility of the PA strains to cefoperazone sodium and sulbac, ampicillin aodium and aulbacta,aiprofloxacin,cefepime,piperacillin/ sulbactam,amikacin, ceftazi-dime,meropenem, imipenem, minocycline, selectrin and aefuroxime was 100%, 76%, 72. 8%, 69. 4%, 66. 3%, 65. 6%, 64. 8%, 59. 9%,28. 9%,2. 4% and 0%,respectively. Conclusion:PA is one of the main pathogenic bacteria for nosocomial infection. It is necessary to strengthen the drug resistance test and standardize the application of antibiotics in order to provide the reference for clinical rational use of antibacterial drugs.
